The zipper machine is a commonly used conveying equipment in the cement industry. For the zipper machine, there are single-point feeding and single-point discharging; there are also multi-point feeding and multi-point unloading. Multi-point unloading often accompanies the problem of carrying materials, such as cement storage. Due to the different types and locations of cement in each warehouse, carrying materials not only affects the quality of cement, but also has the risk of overflowing. Let’s talk about the reasons and treatment methods of carrying materials. .

　　 One, the reason for the material. In fact, the reason for carrying material is very simple, that is, the material stagnating on the track and the upper part of the chain is transported to the halfway or the end of the chain as the chain moves. As time goes by, the material that is scattered on the way may fall into other parts. In the warehouse, it will cause mixed warehouses and affect the quality of cement. The same is true for the materials that are pulled to the rear. If the warehouse is full, it may also cause shells to be exploded. At the same time, it will increase the resistance of the zipper machine and cause waste of energy.

　　 Second, the method of processing strips. The feeding form of the zipper machine is divided into side feeding and upper feeding. When the material is fed from the upper part, the material falling on the chain and the rail will be taken away, and the carried material will be scattered in the middle of the machine, and it will also be carried to the rear of the machine. The treatment method is to change to side feeding or double side feeding to avoid materials falling on the rails and chains. If the upper part of the material must be fed, the upper rail can be cut after 500mm away from the inlet. The rail is cut at two places, the distance is about 1000mm, and the length of the cut is about 150mm. The end is folded down at about 30 degrees to prevent the chain from colliding with the track, so that the chain will jitter and force the material to fall.

　Cut off the track at the feed opening. When the chain pulls the material to the unloading port, most of the material falls into the warehouse, but there is still some material stagnant on the track and chain, and will be pulled back if it is not processed. At this time, the track rail at the unloading port can be cut by 200mm to force the chain to shake there, so that the material on the track loses support here and falls completely. At the same time, because there is no track here, the chain will inevitably tremble here. , The material on the chain will fall down.

　　 Lengthen and widen the discharge chute. If the width of the discharging chute is smaller than the width of the casing, the steps generated by it must aggregate, and the material will be brought to the back when the chain travels, causing mixing; if the discharging chute is too short, part of the material will easily pass through the discharging opening. Even if the track is cut at this location, the vibration amplitude will be small, making the material loading chain continue to move forward.

　　No steps are left at the final discharge end. Some zipper machines are inconsistent with the process, and the final unloading place is still a certain distance from the machine head, and a little material is often brought to the machine head. Although some unloading openings are at the bottom of the machine head, the opening of the lower shell is not opened in the sprocket wheel. The outside of the turning radius also causes aggregates at the steps. Therefore, the location and size of the discharge chute are also critical and must be paid attention to.

　　 Ensure the negative pressure of the case. Ensuring the negative pressure inside the machine looks like an environmental problem, but it is actually closely related to the problem of loading materials. If there is a certain negative pressure in the case, dust will not easily fall on the chain or track, and the problem of loading materials will be relieved to a certain extent.

The belt material of the zipper machine is a small problem, but it is very harmful. It not only involves the quality, but also involves the wear and tear of the parts, and it will increase the power consumption. There is no benefit. The author has encountered the FU410*40000 zipper machine because of The discomfort of the head and tail discharge ports caused aggregates and increased resistance, which affected the transmission. The foot of the reducer was broken. I have also encountered muddy bins due to inadequate valve closure and zipper belt material, so it should cause enough Pay attention.
