Double Ground Screws_Other Equipment_Products

TONY Double Ground Screws is also called two-axis screw conveyor, is in two seamless steel pipe respectively equipped with a solid spiral, one of which is left, the other is right, to avoid material stuck helix, working two helix through a pair of gear meshing rotation in the shaft extension position, due to the rotation of the helix, so that the material for axial movement, so as to achieve the purpose of conveying.

The structure of the double screw conveyor is similar to that of the single shaft screw conveyor, the main difference between the two is that the travel length of the double screw conveyor is usually shorter, and it has the functions of mixing and stirring.

It is mainly used for conveying materials with poor fluidity, and large or large-size materials that need to be stirred. Typically, they operate in a horizontal direction and are suitable for feeding under silos.

The spiral blade is welded on the rotating shaft of TONY Double Ground Screws, and the surface shape of the blade has solid surface type, belt surface type, blade surface type and other types according to the different conveying materials. The screw shaft of the screw conveyor has a thrust bearing at the end of the direction of material movement to react with the axial force of the material to the screw. When the captain is long, the middle hanging bearing should be added.

TONY Double Ground Screws are mainly composed of the following parts:

1.Guard cover

2.Drive part (motor reducer)

3.Feed port (upper)

4.Screw conveying shaft part

(two-axis spiral blade)

5.Discharge opening

(bottom)

6.Shaft seal

7.Outer shell (U-groove type)

TONY Double Ground Screws is a machine that uses a motor to drive the screw to rotate and push the material to achieve the purpose of conveying. When the spiral shaft rotates, due to the gravity of the material and the friction generated between the material and the tank wall, the material can only move forward along the bottom of the conveyor trough under the push of the blade, which is like a nut that cannot rotate along the rotating screw for translation movement. The migration of the material in the middle bearing depends on the thrust of the material moving forward behind it. Therefore, the transport of materials in the conveyor is completely a sliding movement.In order to make the screw shaft in a more favorable tension state, the drive device and the discharge port are generally placed on the same end of the conveyor, and the feed port is placed near the tail of the other end as far as possible. The rotating spiral blade will push the material and transport it, so that the material does not rotate with the spiral conveyor blade is the material's own weight and the friction resistance of the spiral conveyor shell to the material.

1.The two screws rotate through a pair of gears in the shaft extension position. The flow rate of the blade is larger than that of the single screw blade, and the conveying capacity is 1.5-2 times that of the single shaft screw conveyor.

2.Two seamless steel pipes are equipped with solid screws, two screws turn to different directions, can avoid the screw shaft stuck caused by the blocking phenomenon.

3.Can be any point loading and unloading, the middle feed and multi-point feed can be divided into positions, the upper slot cover can be disassembled, easy to check the running status, timely clean up the remaining material.

4.Due to the double screw shaft design, it is equivalent to a mixer mixing materials at the same time, but the price is lower than the mixer, saving costs.

5.Sealing structure, the material will not overflow, will not be polluted by other dust, can prevent the material from being polluted or spilled.

6.There is a discharge valve at the lower end of the feed port, the screw can reverse the discharge, the discharge and cleaning is very convenient.

7.The working intensity and speed of the two screws can be adjusted according to the needs, so that the resources can be allocated and utilized more reasonably

The double-shaft screw conveyor is mainly used in the conveying of powdery, small-diameter particles in the material industry, generally in the horizontal direction of the operation work, suitable for feeding under the bunker, in the metallurgical industry, building materials industry, chemical industry, grain finishing and other industries have been widely used.

1. Powder Material Conveying: Suitable for horizontal or inclined conveying of powder materials, such as lime powder, cement, metal powder, flour, etc.

2. Granular Material Conveying: Suitable for conveying granular materials, such as feed, fertilizer, ore, etc.

3. Mixing Of Mixed Materials: It can be used to mix and stir different materials, such as mixed fertilizer, building materials, etc.

4. Waste Treatment: Can be used for the transportation and treatment of waste, such as garbage, waste, etc.

1. Dual-axis design, the two spiral axes are opposite to avoid clogging

2. Conveying, mixing, pushing and mixing in one, the conveying capacity is 1.5-2 times of the single axis

3. Low cost of feeding and unloading

4. Low noise, good sealing performance

5. Fine workmanship, durable

6. Strong applicability, can be used for different materials

7. Physical factory, can be customized to meet different requirements and product requirements

8.Improve work efficiency, can complete more work tasks in the same time compared to the single ground winch.

9.Because there are two skeins working together, they can balance each other and reduce the vibration and offset of the equipment during the working process, thereby improving the stability and accuracy of the work

10.Widely used in many fields, such as wood processing, biomass pellet processing, feed processing, construction industry and so on

1.The first case is the cause of the stoppage of the spiral shaft.

There are about three reasons for this:

(1) It may be because there is too much feed and overload, resulting in excessive resistance of the lifting shaft, resulting in overload and shutdown of the motor. This situation is to reduce the throughput, uniform speed transmission.

(2) There is a problem with the bearing seal in the middle of the equipment. When the material is transported, the material enters the shaft and damages the bearing. The treatment method is to repair the damaged position of the sealing shaft.

(3) Material problems, because the material particle size, temperature, viscosity and so on are different. Resulting in equipment shell and blade rotation resistance and motor overload. In this case, if the operation continues, the motor will turn on the automatic protection and stop. In this case, it is necessary to check the particle size of the material and give clearance.

2.The second case is shaking when the casing is rotating.

The reason for this situation is that the shaft center line of the installation screw conveyor is not on a horizontal line, and it grinds against the housing when rotating, resulting in

The fuselage shook. The solution to this problem is to adjust the center line of the shaft and install it after unified correction.

3.The third case is that the suspension bearing temperature is high.

There are generally two reasons for the occurrence of this high temperature, one is that the installation position is incorrect, the material is mixed with hard and too large material and the conveyor trough friction, the treatment of this problem is to give the suspension bearing the correct position, if it is the reason of the material, clean out the abnormal material, start to see whether it is normal, and then use.
