Description

Technical Field

[0001] This utility model belongs to the field of cement production technology, and specifically relates to a dust collector used in cement production. Background Technology

[0002] Cement production is an industrial process that transforms raw materials into cement through a series of physical and chemical changes. It is widely used in the construction industry. Its core steps include raw material collection, raw meal preparation, clinker calcination, cement grinding, and finished product packaging. During this process, a large amount of dust is generated in the production site, so it is usually necessary to equip the site with a dust collector specifically for cement production to control dust pollution.

[0003] Existing dust collectors used in cement production mostly adopt the principle of negative pressure dust collection. The filter surface of the internal filter screen is equipped with cleaning brushes to periodically remove the dust attached to the filter screen surface in order to maintain filtration efficiency. However, in actual use, it has been found that the brushes of this type of dust collector are still exposed to the dusty environment for a long time when not in operation, which easily leads to dust accumulation and wear, resulting in a significant decrease in cleaning effect, shortening the service life of the brush roller, and thus affecting the overall operating efficiency and reliability of the equipment. Utility Model Content

[0004] In view of this, the present invention provides a dust collector for cement production, which avoids the problem of reduced cleaning ability caused by prolonged exposure of the brush roller to a dusty environment through a cleaning mechanism. It can effectively seal and protect the brush roller when not in operation, ensuring the best cleaning effect for each use, while extending the service life of the brush roller and improving the reliability and operating efficiency of the entire equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides a dust collector for cement production, including a dust collection box and a dust collection mechanism disposed therein. The dust collection mechanism includes a filter cylinder rotatably connected to the inner cavity of the dust collection box. The dust collection box is also provided with a cleaning mechanism for cleaning the filter surface of the filter cylinder. The cleaning mechanism includes a U-shaped plate disposed in the dust collection box. A rotating frame is rotatably connected between the two ends of the inner cavity of the U-shaped plate. A brush roller is disposed between the two ends of the inner cavity of the rotating frame. This avoids the problem of the brush roller being exposed to the dusty environment for a long time, which would lead to a decrease in cleaning ability. It can effectively seal and protect the brush roller when it is not in operation, ensuring the best cleaning effect for each use. At the same time, it extends the service life of the brush roller and improves the reliability and operating efficiency of the entire equipment.

[0006] The cleaning mechanism also includes a motor located at one end of the dust collection box. The output shaft of the motor is fixedly connected to one end of the rotating frame, thus providing a drive source for the rotating frame.

[0007] The cleaning mechanism also includes sealing gaskets on both sides of the lower end of the rotating frame. The inner cavity of the U-shaped plate is in contact with the adjacent sealing gasket on the same side, which serves to seal the surface.

[0008] The lower ends of the rotating frame are curved on both sides to ensure smooth rotation.

[0009] The dust collection port at the bottom of the dust collection box is equipped with a cover plate, which makes it easy for relevant personnel to clean the dust collector in cement production.

[0010] The dust collection mechanism also includes dust collection heads installed in the dust inlets on both sides of the dust collection box. A fan is installed at one end of the dust collection box near the opening of the filter cartridge, and a second motor is installed at the other end of the dust collection box. The output shaft of the second motor is fixedly connected to one end of the filter cartridge, which serves to collect dust in the cement production site.

[0011] The brushes of the brush roller make active contact with the filter surface of the filter cartridge, thus ensuring a cleaning effect.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. When the motor starts, its output shaft rotates, driving the rotating frame and brush roller to rotate, thus rotating the brush roller out of the U-shaped plate, ultimately causing the bristles of the brush roller to contact the filter surface of the filter cartridge. During this process, the lower end of the rotating frame is parallel to the opening of the U-shaped plate and is tightly fitted to the inner wall of the U-shaped plate through a sealing gasket, forming a sealed environment to prevent dust intrusion. Simultaneously, the second motor starts, and its output shaft rotates, driving the filter cartridge to rotate, thereby cleaning the filter surface of the filter cartridge. The cleaned dust falls to the bottom of the dust collection box and is periodically discharged through the dust removal port cover. When the brush roller is not in use, the first motor restarts... Upon startup, the output shaft rotates, driving the rotating frame and brush roller to rotate, thus rotating the brush roller into the U-shaped plate. At this time, the lower end of the rotating frame is parallel to the opening of the U-shaped plate, and simultaneously, it is tightly fitted to the inner wall of the U-shaped plate through a sealing gasket, forming a sealed environment to prevent dust intrusion. This protects the cleaning effect of the brush roller and avoids the problem of reduced cleaning ability caused by prolonged exposure of the brush roller to a dusty environment. It can effectively seal and protect the brush roller when it is not in operation, ensuring the best cleaning effect for each use, while extending the service life of the brush roller and improving the reliability and operating efficiency of the entire equipment.

[0014] 2. The swept dust falls to the bottom of the dust collection box and is periodically discharged through the cover of the dust removal port, making it convenient for relevant staff to clean it.

[0015] 3. First, move the dust collection head to the dust collection area. Then, the fan operates to generate negative pressure and draws the flue gas into the dust collection box through the dust collection head. During this process, the dust is filtered through the filter cartridge, and the particulate matter is intercepted on the filter surface. The purified gas is discharged from the outlet.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a dust collector for cement production, such as... Figure 1-4The dust collection system includes a dust collection box 100 and a dust collection mechanism disposed therein. The dust collection mechanism includes a filter cartridge 400 rotatably connected to the inner cavity of the dust collection box 100. One end of the filter cartridge 400 is open. The dust collection mechanism also includes dust collection heads 401 disposed in the dust inlets on both sides of the dust collection box 100. The dust collection heads 401 are corrugated dust collection heads. A fan 402 is provided at one end of the dust collection box 100 near the open end of the filter cartridge 400, and a second motor 403 is provided at the other end of the dust collection box 100. The output shaft of the second motor 403 is fixedly connected to one end of the filter cartridge 400. The dust collection box 100 also contains a filter for... The cleaning mechanism for cleaning the filter surface of the cylinder 400 includes a U-shaped plate 200 disposed inside the dust collection box 100. A rotating frame 201 is rotatably connected between the two ends of the inner cavity of the U-shaped plate 200. A brush roller 202 is disposed between the two ends of the inner cavity of the rotating frame 201. The cleaning mechanism also includes a motor 203 disposed at one end of the dust collection box 100. The output shaft of the motor 203 is fixedly connected to one end of the rotating frame 201. The cleaning mechanism also includes sealing gaskets 204 disposed on both sides of the lower end of the rotating frame 201. Both sides of the inner cavity of the U-shaped plate 200 are in movable contact with the adjacent sealing gaskets 204 on the same side.

[0023] First, the dust collection head 401 is moved to the dust collection area. Then, the fan 402 operates to generate negative pressure, drawing the flue gas into the dust collection box 100 through the dust collection head 401. During this process, dust is filtered by the filter cartridge 400, and particulate matter is intercepted on the filter surface. The purified gas is discharged from the outlet. To maintain filtration efficiency, motor 203 starts, and its output shaft rotates to drive the rotating frame 201 and brush roller 202 to rotate, thereby rotating the brush roller 202 out of the U-shaped plate 200. Finally, the bristles of the brush roller 202 come into contact with the filter surface of the filter cartridge 400. During this process, the lower end of the rotating frame 201 is parallel to the opening of the U-shaped plate 200 and is tightly fitted to the inner wall of the U-shaped plate 200 through the sealing gasket 204, forming a sealed environment to prevent dust intrusion. At the same time, motor 403 starts synchronously, and its output shaft rotates to drive the filter cartridge 400 to rotate. The system cleans the filter surface of the filter cartridge 400, and the cleaned dust falls to the bottom of the dust collection box. When the brush roller 202 is not in use, the motor 203 restarts, and its output shaft rotates to drive the rotating frame 201 and the brush roller 202 to rotate, thereby rotating the brush roller 202 into the U-shaped plate 200. At this time, the lower end of the rotating frame 201 is parallel to the opening of the U-shaped plate 200, and at the same time, it is tightly attached to the inner wall of the U-shaped plate 200 through the sealing gasket 204 to form a sealed environment to prevent dust from entering. This protects the cleaning effect of the brush roller 202 and avoids the problem of the brush roller 202 being exposed to a dusty environment for a long time, which would lead to a decrease in cleaning ability. It can effectively seal and protect it when it is not in use, ensuring the best cleaning effect every time it is used, while extending the service life of the brush roller 202 and improving the reliability and operating efficiency of the entire equipment.

[0024] like Figure 1-4 As shown, the lower ends of the rotating frame 201 have arc-shaped structures on both sides to ensure that the rotating frame 201 can rotate smoothly.

[0025] like Figure 1-4 As shown, the dust collection box 100 has a dust removal port with a cover plate 300 at the lower end. The dust that is swept down falls into the bottom of the dust collection box and is periodically discharged through the dust removal port cover plate 300.

[0026] like Figure 1-4 As shown, the brush of the brush roller 202 is in active contact with the filter surface of the filter cylinder 400, ensuring that the brush bristles can contact the filter surface of the filter cylinder 400 after the brush roller 202 rotates out of the U-shaped plate 200, thus ensuring the cleaning effect.

[0027] The working principle of the dust collector for cement production provided by this utility model is as follows: First, the dust collection head 401 is moved to the dust collection area. Then, the fan 402 operates to generate negative pressure and draws the flue gas into the dust collection box 100 through the dust collection head 401. During this process, the dust is filtered by the filter cylinder 400, and the particulate matter is intercepted on the filter surface. The purified gas is discharged from the outlet. In order to maintain the filtration efficiency, the motor 203 is started, and its output shaft rotates to drive the rotating frame 201 and the brush roller 202 to rotate, thereby rotating the brush roller 202 out of the U-shaped plate 200. Finally, the bristles of the brush roller 202 come into contact with the filter surface of the filter cylinder 400. During this process, the lower end of the rotating frame 201 is parallel to the opening of the U-shaped plate 200 and is tightly fitted to the inner wall of the U-shaped plate 200 through the sealing gasket 204 to form a sealed environment to prevent dust from entering. At the same time, the motor 403 is started synchronously, and its output shaft rotates to drive the filter cylinder 401 to rotate. The motor rotates at 00, thus cleaning the filter surface of the filter cartridge 400. The cleaned dust falls to the bottom of the dust collection box and is periodically discharged through the cover plate 300 of the dust removal port. When the brush roller 202 is not in use, the motor 203 restarts, and its output shaft rotates to drive the rotating frame 201 and the brush roller 202 to rotate, thereby rotating the brush roller 202 into the U-shaped plate 200. At this time, the lower end of the rotating frame 201 is parallel to the opening of the U-shaped plate 200, and at the same time, it is tightly attached to the inner wall of the U-shaped plate 200 through the sealing gasket 204 to form a sealed environment to prevent dust from entering, thereby protecting the cleaning effect of the brush roller 202 and avoiding the problem of the brush roller 202 being exposed to the dusty environment for a long time, which would lead to a decrease in cleaning ability. It can effectively seal and protect it in the non-working state, ensuring the best cleaning effect every time it is used, while extending the service life of the brush roller 202 and improving the reliability and operating efficiency of the entire equipment.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
