Description

Technical Field

[0001] The utility model relates to the technical field of dust removal pipes, in particular to a dust removal pipe for a liquid workshop. Background Art

[0002] Dust removal ducts are piping systems used to collect and transport solid waste and dust, and are widely used in industries such as coal, electricity, building materials, metallurgy, and cement. Their primary function is to reduce environmental pollution from dust generated during industrial production and improve production efficiency. Liquid fertilizer dust removal ducts are piping systems used to remove dust particles from dust-laden gases during liquid fertilizer production.

[0003] The aforementioned and existing technologies suffer from the following drawbacks: During the actual liquid fertilizer production process, chemical substances contained in the fertilizer crystallize on the inner walls of the pipe due to temperature. The crystals gradually accumulate on the inner walls of the pipe, reducing the inner diameter of the pipe and obstructing the normal flow of dust-laden gas. This not only increases resistance to gas flow but can also cause localized airflow obstruction, affecting the ventilation effectiveness of the entire dust removal system, thereby reducing dust capture and significantly decreasing dust removal efficiency.

[0004] Therefore, a dust removal pipeline for a liquid workshop is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the problem of chemical substances contained in fertilizers crystallizing on the inner wall of the pipe due to temperature. The crystals gradually accumulate on the inner wall of the pipe, reducing the inner diameter of the pipe and hindering the normal flow of dust-laden gas. This not only increases the resistance to gas flow, but may also cause local airflow obstruction, affecting the ventilation effect of the entire dust removal system, thereby reducing the dust capture ability and significantly reducing dust removal efficiency. The proposed dust removal pipe for liquid workshops is designed to solve the problem of chemical substances contained in fertilizers crystallizing on the inner wall of the pipe due to temperature. The crystals gradually accumulate on the inner wall of the pipe, reducing the inner diameter of the pipe and hindering the normal flow of dust-laden gas. This not only increases the resistance to gas flow, but also may cause local airflow obstruction, affecting the ventilation effect of the entire dust removal system, thereby reducing the dust capture ability and significantly reducing dust removal efficiency.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a dust removal pipe for a liquid workshop, comprising a pipe body, a scraping device provided on the surface of the pipe body, the scraping device comprising two connecting rings, both of which are flange-connected to the pipe body, the arc surface of the connecting ring is rotatably connected to a rotating ring, the surface of the rotating ring is threadedly connected to two screw rods, the arc surfaces of the two screw rods are threadedly connected to positioning plates, the surface of the positioning plate is fixedly connected to a scraper, the scraper abuts against the inner wall of the pipe body, the surface of the rotating ring is fixedly connected to a telescopic rod, the surface of the telescopic rod is fixedly connected to a push rod, and the push rod is clamped with the connecting ring.

[0007] The above components achieve the following effect: by providing a scraping device and utilizing the coordination between the connecting ring, rotating ring, screw, positioning plate, scraper, telescopic rod, and push rod, crystalline materials on the inner wall of the pipe can be scraped off. This prevents the chemical substances contained in the fertilizer from crystallizing on the inner wall of the pipe due to the influence of temperature. The crystalline materials gradually accumulate on the inner wall of the pipe, which reduces the inner diameter of the pipe and hinders the normal flow of dust-laden gas. This not only increases the resistance to gas flow, but may also cause local airflow obstruction, affecting the ventilation effect of the entire dust removal system, thereby reducing the dust capture ability, significantly reducing the dust removal efficiency, and improving the utilization efficiency of the dust removal pipe.

[0008] Preferably, a spring is sleeved on the surface of the telescopic rod, and two ends of the spring are fixedly connected to the rotating ring and the push rod respectively.

[0009] The effect achieved by the above components is: the push rod drives one end of the spring to move, and then the spring itself generates a retraction force, at which time the spring can quickly reset the push rod.

[0010] Preferably, the arc surface of the rotating ring is rotatably connected to a plurality of balls, and the plurality of balls are all slidably connected to the connecting ring.

[0011] The effect achieved by the above components is that the rotating ring drives the balls to slide along the surface of the connecting ring, and at this time the balls can reduce the friction between the contact surface of the connecting ring and the rotating ring.

[0012] Preferably, a sealing gasket is fixedly connected to the surface of the connecting ring, and the sealing gasket abuts against the tube body.

[0013] The effect achieved by the above components is that one end of the tube body will abut against the sealing gasket on the connecting ring, and at this time the sealing gasket can seal the contact surface between the tube body and the connecting ring.

[0014] Preferably, a scraping strip is fixedly connected to the surface of the scraper, and the scraping strip abuts against the inner wall of the tube body.

[0015] The effect achieved by the above components is that the scraper drives the scraper bar to rotate in the same direction, and at this time the scraper bar can better scrape off the crystallized material on the inner wall of the tube body.

[0016] Preferably, a brush plate is fixedly connected to the surface of the scraper, and the brush plate abuts against the inner wall of the tube body.

[0017] The effect achieved by the above components is that the scraper drives the brush plate to brush along the inner wall of the tube body, and the brush plate can clean the crystallized material on the inner wall of the tube body scraped by the scraper.

[0018] Preferably, the arc surface of the screw rod is covered with an anti-slip pad, and the anti-slip pad is a rubber pad.

[0019] The effect achieved by the above components is that the screw rod will drive the anti-slip pad to move with the help of its own thread. At this time, the anti-slip pad made of rubber can increase the friction between the screw rod and the positioning plate to prevent the screw rod from slipping.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are:

[0021] In the present invention, by providing a scraping device and utilizing the coordination among a connecting ring, a rotating ring, a screw, a positioning plate, a scraper, a telescopic rod, and a push rod, crystalline substances on the inner wall of the pipe body can be scraped off. This prevents the chemical substances contained in the fertilizer from crystallizing on the inner wall of the pipe due to the influence of temperature. The crystalline substances gradually accumulate on the inner wall of the pipe, which reduces the inner diameter of the pipe and hinders the normal circulation of dust-laden gas. This not only increases the resistance to gas flow, but may also cause local airflow obstruction, affecting the ventilation effect of the entire dust removal system, thereby reducing the dust capture ability and significantly reducing the dust removal efficiency, thereby improving the utilization efficiency of the dust removal pipe.

[0028] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figure 1-Figure 5 As shown, the utility model provides a dust removal pipe for a liquid workshop, comprising a pipe body 1, and a scraping device 2 is provided on the surface of the pipe body 1.

[0031] The specific configuration and function of the scraping device 2 will be described in detail below.

[0032] like Figure 2-Figure 5As shown, the scraping device 2 includes two connecting rings 201, both of which are flange-connected to the pipe body 1, and the arc surface of the connecting ring 201 is rotatably connected to the rotating ring 202, and the surface of the rotating ring 202 is threadedly connected to two screw rods 203, and the arc surfaces of the two screw rods 203 are threadedly connected to positioning plates 204, and the surface of the positioning plate 204 is fixedly connected to a scraper 205, and the scraper 205 abuts against the inner wall of the pipe body 1, and the surface of the rotating ring 202 is fixedly connected to a telescopic rod 206, and the surface of the telescopic rod 206 is fixedly connected to a push rod 207, and the push rod 207 is snap-fitted to the connecting ring 201. The surface of the telescopic rod 206 is covered with a spring 208, and the two ends of the spring 208 are fixedly connected to the rotating ring 202 and the push rod 207 respectively. The push rod 207 drives one end of the spring 208 to move, and then the spring 208 itself will generate a retraction tension. At this time, the spring 208 can realize the rapid reset of the push rod 207. The arc surface of the rotating ring 202 is connected to a plurality of balls 209, and the plurality of balls 209 are all slidably connected to the connecting ring 201. The rotating ring 202 drives the balls 209 to slide along the surface of the connecting ring 201. At this time, the balls 209 can reduce the connection. The friction between the contact surface of the ring 201 and the rotating ring 202, the surface of the connecting ring 201 is fixedly connected with a sealing gasket 210, the sealing gasket 210 abuts against the tube body 1, and one end of the tube body 1 abuts against the sealing gasket 210 on the connecting ring 201. At this time, the sealing gasket 210 can seal the contact surface between the tube body 1 and the connecting ring 201, and the surface of the scraper 205 is fixedly connected with a scraping strip 211, the scraping strip 211 abuts against the inner wall of the tube body 1, and the scraper 205 drives the scraping strip 211 to rotate in the same direction. At this time, the scraping strip 211 can better scrape off the crystalline material on the inner wall of the tube body 1, and the scraping A brush plate 212 is fixedly connected to the surface of the plate 205, and the brush plate 212 is in contact with the inner wall of the tube body 1. The scraper 205 will drive the brush plate 212 to brush along the inner wall of the tube body 1. At this time, the brush plate 212 can clean the crystalline material on the inner wall of the tube body 1 scraped by the scraper 205. The arc surface of the screw rod 203 is covered with an anti-slip pad 213, and the anti-slip pad 213 is a rubber pad. The screw rod 203 will use its own thread to drive the anti-slip pad 213 to move. At this time, the rubber anti-slip pad 213 can increase the friction between the screw rod 203 and the positioning plate 204 to prevent the screw rod 203 from slipping.

[0033] The overall working principle is that when the inner wall of the tube body 1 needs to be cleaned, the tube body 1 is first flange-connected to the connecting ring 201, and then one end of the tube body 1 will abut against the sealing gasket 210 on the connecting ring 201. At this time, the sealing gasket 210 can seal the contact surface between the tube body 1 and the connecting ring 201, and then the push rod 207 is pulled away from the tube body 1, and then the push rod 207 will drive one end of the telescopic rod 206 to move, and at the same time, the push rod 207 will drive one end of the spring 208 to move, and then the spring 208 itself will generate a retraction force. At this time, the spring 208 can realize the rapid reset of the push rod 207, and then when the push rod 20 When 7 is separated from the connecting ring 201, the push rod 207 is rotated along the arc surface of the connecting ring 201. At this time, the push rod 207 drives the telescopic rod 206 to rotate. At the same time, the telescopic rod 206 drives the rotating ring 202 to rotate along the arc surface of the connecting ring 201. Then, the rotating ring 202 drives the ball 209 to slide along the surface of the connecting ring 201. At this time, the ball 209 can reduce the friction between the contact surface of the connecting ring 201 and the rotating ring 202. Then, the rotating ring 202 drives the screw rod 203 to rotate. At the same time, the screw rod 203 drives the positioning plate 204 to rotate. Then, the positioning plate 204 drives the scraper 205 to slide along the inner surface of the tube body 1. The scraper 205 is scraped off the inner wall of the tube body 1, and then the scraper 205 drives the scraper bar 211 to rotate in the same direction. At this time, the scraper bar 211 can better scrape off the crystalline material on the inner wall of the tube body 1. At the same time, the scraper 205 drives the brush plate 212 to brush along the inner wall of the tube body 1. At this time, the brush plate 212 can clean the crystalline material on the inner wall of the tube body 1 scraped by the scraper 205. When the scraper 205 needs to be replaced, it is only necessary to remove the screw rod 203 from the positioning plate 204 and the rotating ring 202, and then rotate the screw rod 203 to thread the screw rod 203 with the new scraper 205. At the same time, the screw rod 203 will drive the anti-slip pad 213 to move with its own thread. At this time, The rubber anti-skid pad 213 can increase the friction between the screw rod 203 and the positioning plate 204 to prevent the screw rod 203 from slipping. Then, the screw rod 203 is threadedly connected to the connecting ring 201. By setting the scraping device 2, the connection ring 201, the rotating ring 202, the screw rod 203, the positioning plate 204, the scraper 205, the telescopic rod 206 and the push rod 207 are used to scrape the crystalline material on the inner wall of the pipe body 1, thereby preventing the chemical substances contained in the fertilizer from crystallizing on the inner wall of the pipe due to the influence of temperature. The crystalline material gradually accumulates on the inner wall of the pipe, which reduces the inner diameter of the pipe and hinders the normal circulation of dust-laden gas. This not only increases the resistance to gas flow, but also may cause local airflow obstruction, affecting the ventilation effect of the entire dust removal system, thereby reducing the dust capture ability, significantly reducing the dust removal efficiency, and improving the use efficiency of the dust removal pipe.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
