[0002] The rotary kiln is equipped with a fan room and a chain plate room. The fan room is located on the top of the chain plate room. Due to safety requirements, a safety passage is set between the two.
[0003] However, in the existing technology, due to the large air volume of the existing rotary kiln fan, a large amount of air enters the fan room from the chain plate room along the safety passage, and the air carries some dust during the circulation process, resulting in poor air quality inside the fan room. In addition, there is a lack of dust collector in the chain plate room, and the dust in the air is difficult to control. Adding a new dust collector requires a lot of money.
[0004] Therefore, we need a new type of ventilation equipment for rotary kiln cooling air, which can effectively solve the problem of poor air environment in the fan room and chain plate room of the existing rotary kiln, and can also realize and reduce the additional cost of dust collector.

[0007] Preferably, the top surface of the cooling chamber contacts the bottom surface of the dust removal bellows, a sealing groove is provided on the top surface of the dust removal bellows, the surface of the sealing groove is clamped to the surface of the sealing plate, a buckle groove is provided on the top surface of the sealing plate, and the bottom surface of the sealing plate is fixedly connected to the filter frame.
[0008] Preferably, an integrally formed isolation plate is provided on the inner surface of the dust removal air box. There are two isolation plates, and the two isolation plates are symmetrically arranged along the center point of the dust removal air box. The distance between the two isolation plates is equal to the width dimension of the filter screen frame, and the surface of the filter screen frame contacts the side surface of the isolation plate.

By arranging a cooling air cap on the surface of the air outlet pipe, the end of the output pipe of the cooling air cap penetrates through the side surface of the dust removal air box, changing the air outlet direction of the air outlet pipe. The dust on the top surface of the sealing plate is blown away through the dust removal air outlets on the surface of the dust removal air box. Thus, the dust removal air box can continuously remove dust from the top surface of the cooling chamber by the power provided by the centrifugal fan. Therefore, when the branch pipe conveys air into the dust removal air box, the air inside the dust removal air box is filtered through the filter screen frame. Therefore, the filter screen frame can filter the dust carried in the air transported by the centrifugal fan into the dust removal air box, and thus the dust removal air box plays a role in collecting dust. The surface of the filter screen frame is abutted against the surface of the isolation plate, so that the isolation plate plays an isolation role inside the dust removal air box, and at the same time, the filter screen frame plays a blocking role in the filtering and dust collection inside the dust removal air box; further solving the problem that the existing rotary kiln effectively solves the problem of poor air environment in the fan room and the chain plate machine room, and can also realize and reduce the new cost of the dust collector.
