Nozzles are evenly distributed on the lower end surface of the venturi tube. A support rod is provided below the nozzles, and the left and right sides of the support rod are fixedly connected to the inner wall of the bag filter body.

[0004] Existing dust removal devices in cement production are mostly bag filters, which are equipped with back-blowing components to clean the dust adhering to the outside of the filter bags. In practice, when the filter bags are back-blown, the dust that naturally falls to the bottom of the silo is easily stirred up by the high-pressure gas, which is not conducive to the rapid removal of dust. Therefore, there is an urgent need to propose a corresponding dust removal device for cement production to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a dust removal device for cement production in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dust removal device for cement production includes a bag filter and a buffer chamber integrated at the bottom of the bag filter. A side chamber is fixedly connected to the outside of the buffer chamber, and a sealing component for sealing the inside of the buffer chamber is provided on the inside of the side chamber. A bottom pipe is fixedly connected to the bottom of the buffer chamber, and a valve is provided inside the bottom pipe. A discharge pipe is connected to the bottom of the bottom pipe.

[0007] Preferably, the inner surface of the top of the feed tube is rotatably connected to the outer surface of the bottom of the bottom tube via a bearing, and the top of the bottom tube is fixedly connected to the outer surface of the bottom tube via a locking part.

[0008] Preferably, the locking part includes a top seat fixedly connected to the top of the vertical end of the feed tube, and a positioning rod is screwed onto the inner surface wall of the top seat, with the open end of the positioning rod abutting against the outer surface wall of the bottom tube.

[0009] Preferably, the open end of the positioning rod is covered with an anti-slip silicone pad.

[0010] Preferably, a connecting flange is fixedly connected to the open end of the feed pipe.

[0011] Preferably, the sealing assembly includes a push cylinder fixedly connected to the outer wall of the side compartment, and a sealing plate is fixedly connected to the output end of the push cylinder.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this application, when the bag filter is operating normally, the valve is in the closed state, while the sealing plate is in the open state. The normally falling cement dust will accumulate inside the buffer chamber. When cleaning is required, the push cylinder pushes the sealing plate to close the top of the buffer chamber and open the valve, so that while the bag is being washed, the dust inside the buffer chamber is discharged first, and the washed cement dust will fall onto the top of the sealing plate. After the washing process is completed, the sealing plate is reset, and the dust on the top of the sealing plate continues to be discharged. This improves the efficiency of dust discharge while ensuring the cleaning effect of cement dust.

[0013] 2. In this application, the feeding pipe is rotated to a suitable angle. The bearing with a sealing structure ensures the rotational fit and sealing between the bottom pipe and the feeding pipe. Then, the positioning rod is rotated to engage with the top seat. The axial locking of the feeding pipe is achieved through the contact friction between the positioning rod and the outer wall of the bottom pipe. This allows for convenient adjustment of the axial position of the feeding pipe according to the connection requirements of the outer pipe, thereby improving the applicability of the dust removal device for cement production.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: A dust removal device for cement production includes a bag filter 1 and a buffer chamber 2 integrated at the bottom of the bag filter 1. A side chamber 5 is fixedly connected to the outside of the buffer chamber 2. A sealing component for sealing the inside of the buffer chamber 2 is provided inside the side chamber 5. A bottom pipe 3 is fixedly connected to the bottom of the buffer chamber 2. A valve 10 is provided inside the bottom pipe 3, and a discharge pipe 4 is connected to the bottom of the bottom pipe 3. When the bag filter 1 is operating normally, valve 10 is closed and sealing plate 8 is open. Normally falling cement dust will accumulate inside the buffer chamber 2. When cleaning is required, the push cylinder 6 pushes the sealing plate 8 to close the top of the buffer chamber 2 and the valve 10 opens. This allows the dust inside the buffer chamber 2 to be discharged first while the bag is being washed, and the washed-down cement dust will fall onto the top of the sealing plate 8. After the washing process is completed, the sealing plate 8 is reset, and the dust on the top of the sealing plate 8 continues to be discharged. This improves the efficiency of dust discharge while ensuring the cleaning effect of cement dust.

[0018] Specifically, such as Figure 2 and Figure 4 As shown, the inner surface of the top of the feed pipe 4 is rotatably connected to the outer surface of the bottom of the bottom pipe 3 via a bearing 7, and the top of the bottom pipe 3 is fixedly connected to the outer surface of the bottom pipe 3 via a locking part. The locking part includes a top seat 12 fixedly connected to the top of the vertical end of the feed pipe 4. A positioning rod 11 is screwed onto the inner surface of the top seat 12, and the open end of the positioning rod 11 abuts against the outer surface of the bottom pipe 3. The feed pipe 4 is rotated to deflect to a suitable angle. The bearing 7 with a sealing structure ensures the rotational fit and sealing between the bottom pipe 3 and the feed pipe 4. Then, the positioning rod 11 is rotated to screw onto the top seat 12. The axial locking of the feed pipe 4 is achieved through the contact friction between the positioning rod 11 and the outer surface of the bottom pipe 3. This allows for convenient adjustment of the axial position of the feed pipe 4 according to the external pipe connection requirements, thereby improving the applicability of the dust removal device for cement production. The open end of the positioning rod 11 is wrapped with an anti-slip silicone pad to ensure the stability of the contact between the positioning rod 11 and the outer surface of the bottom pipe 3.

[0019] Specifically, such as Figure 2 and Figure 3As shown, the open end of the feed pipe 4 is fixedly connected to a connecting flange 9, which facilitates the connection of the feed pipe 4 to an external pipe. The sealing assembly includes a push cylinder 6 fixedly connected to the outer wall of the side chamber 5, and a sealing plate 8 is fixedly connected to the output end of the push cylinder 6. The push cylinder 6 pushes the sealing plate 8 to close the top of the buffer chamber 2.

[0020] Working principle: When the bag filter 1 is running normally, valve 10 is closed and sealing plate 8 is open. Normally falling cement dust will accumulate inside the buffer chamber 2. When cleaning is required, the push cylinder 6 pushes the sealing plate 8 to close the top of the buffer chamber 2 and open valve 10. This allows the dust inside the buffer chamber 2 to be discharged first while the bag is being washed, and the washed cement dust will fall onto the top of the sealing plate 8. After the washing process is completed, the sealing plate 8 is reset, and the dust on the top of the sealing plate 8 continues to be discharged. This improves the efficiency of dust discharge and ensures the cleaning effect of cement dust. Rotate the feed pipe 4 to deflect it to a suitable angle. The bearing 7 with a sealing structure ensures the rotational fit and sealing between the bottom pipe 3 and the feed pipe 4. Then rotate the positioning rod 11 to screw it into the top seat 12. The contact friction between the positioning rod 11 and the outer wall of the bottom pipe 3 achieves the axial locking of the feed pipe 4. This allows for convenient adjustment of the axial position of the feed pipe 4 according to the external pipe connection requirements, thereby improving the applicability of the cement production dust removal device.
