Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors for sand and gravel aggregate processing, and particularly relates to an automatic dust removal device for a sand and gravel aggregate production line. Background Technique

[0002] Sand and gravel aggregates mainly refer to materials such as sand, gravel, and crushed gravel used in construction and civil engineering. These are usually the basic components of concrete, asphalt, and other building materials. Sand and gravel aggregates are one of the most used raw materials in the construction industry, and their quality directly affects the strength and durability of buildings. During production, if dust and impurities in sand and gravel aggregates are not removed, they will affect the quality of concrete and other building materials. Dust will reduce the bonding force between cement and aggregates in concrete, thus affecting its structural strength and durability.

[0003] The commonly used automatic dust removal devices in traditional sand and gravel aggregate production lines mainly include bag filters and cyclone dust collectors. In a cyclone dust collector, sand and gravel aggregates enter the device in a high-speed rotating manner, and the centrifugal force is used to separate dust particles from the gas. The heavier dust particles are thrown towards the wall of the device due to the centrifugal force and then fall into the dust collection bucket below, while the clean air is discharged from the outlet at the top. Cyclone dust collectors are particularly suitable for removing larger particle dust, and the trapping efficiency for fine dust is relatively low. For this reason, an automatic dust removal device for a sand and gravel aggregate production line is proposed to solve the above problems. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an automatic dust removal device for a sand and gravel aggregate production line, aiming to improve the problem of insufficient dust cleaning caused by the relatively single structure in the prior art.

[0011] As a further description of the above technical solution:

[0012] The fixing component includes an L-shaped frame. The side wall of the L-shaped frame is fixedly connected to the side wall of the box body. A fixing pin is slidably connected inside the L-shaped frame. A limiting hole is formed inside the filter screen;

[0013] As a further description of the above technical solution:

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 - Figure 2 , an embodiment provided by the present invention: an automatic dust removal device for a sand and gravel aggregate production line, including a box body 1, a rotating shaft 2 is rotatably connected inside the box body 1, a pushing plate 3 is fixedly connected to the side wall of the rotating shaft 2, a crank 4 is rotatably connected inside the box body 1, the crank 4 is arranged at the bottom of the pushing plate 3, a rotating column 5 is fixedly connected to the side wall of the crank 4, the side wall of the rotating column 5 is rotatably connected inside the box body 1, a runner 6 is fixedly connected to the side wall of the rotating column 5, a belt 7 is arranged between the runners 6, a fixed frame 8 is fixedly connected to the rear side wall of the box body 1, a motor 9 is fixedly connected to the side wall of the fixed frame 8, the output end of the motor 9 is fixedly connected to the side wall of one of the runners 6, a connecting plate 10 is rotatably connected to the side wall of the crank 4, a fixed seat 11 is fixedly connected inside the box body 1, a sleeve 12 is fixedly connected inside the fixed seat 11, a slide bar 13 is slidably connected inside the sleeve 12, a pulley 14 is rotatably connected inside the slide bar 13, one side of the connecting plate 10 is rotatably connected to the lower surface of the slide bar 13, a first spring 15 is sleeved on the side wall of the slide bar 13, one end of the first spring 15 is fixedly connected to the lower surface of the sleeve 12, and the other end of the first spring 15 is fixedly connected to the side wall of the slide bar 13. A collection assembly is arranged inside the box body 1, and the collection assembly includes a guide plate 16 and a collection box 17. The side wall of the guide plate 16 is fixedly connected inside the box body 1, the guide plate 16 is arranged at the bottom of the pushing plate 3, and the side wall of the collection box 17 is slidably connected inside the box body 1;

[0032] Sand and gravel aggregates are introduced into the internal space of the box body 1 through the top feed pipe of the box body 1. During this process, the motor 9 is started simultaneously to drive the rotating wheel 6 on one side to start rotating. As the motor 9 operates, under the driving action of the belt 7, it drives the rotating wheel 6 on the other side to rotate synchronously, further driving the two-sided crank 4 to rotate continuously. During the rotation of the crank 4, it will cause one side of the connecting plate 10 to move. At the same time, the other side of the connecting plate 10 rotates and rises under the support of the sliding rod 13. This action enables the pulley 14 to slide on the lower surface of the push plate 3. As the pulley 14 moves, the push plate 3 tilts around the rotating shaft 2. This action throws the sand and gravel aggregates upward, so that the dust inside the aggregates can be released and diffused upward. The connecting plate 10 will move back and forth within a certain range as the crank 4 continues to rotate. Such an action enables the sliding rod 13 to move up and down reciprocally. Through this reciprocating motion, the sand and gravel aggregates are continuously jolted up, achieving the purpose of effective dust removal. After a series of treatment processes, the sand and gravel aggregates will finally be guided along the direction of the guiding plate 16 and evenly fall into the interior of the collection box 17, completing the entire sand and gravel aggregate treatment process.

[0033] Refer to Figure 3 - Figure 4 , a concave hole 18 is provided inside the box body 1, a filter frame 19 is slidably connected inside the box body 1, a filter screen 20 is fixedly connected inside the filter frame 19, a fixed cover 21 is fixedly connected to the side wall of the box body 1, a fan 22 is arranged inside the fixed cover 21, a fixing component is arranged on the side wall of the box body 1, the fixing component includes an L-shaped frame 23, the side wall of the L-shaped frame 23 is fixedly connected to the side wall of the box body 1, a fixing pin 24 is slidably connected inside the L-shaped frame 23, a limiting hole 28 is provided inside the filter screen 20, a limiting ring 25 is fixedly connected to the side wall of the fixing pin 24, a pull ring 27 is fixedly connected to the side wall of the fixing pin 24, a second spring 26 is sleeved on the side wall of the fixing pin 24, one end of the second spring 26 is fixedly connected to the side wall of the limiting ring 25, the other end of the second spring 26 is fixedly connected to the side wall of the L-shaped frame 23, the side wall of the fixing pin 24 penetrates through the side wall of the box body 1 and is slidably connected inside the limiting hole 28, there are two filter screens 20, and the filter screens 20 are arranged between the fan 22 and the concave hole 18.

[0034] Start the fan 22 to generate a strong suction force. This suction force acts on the surrounding air through the concave holes 18, thereby sucking away the dust particles suspended in the air. Under the action of the fan 22, these dusts will be effectively sucked and finally deposited on the filter screen 20. The filter screen 20 plays a role in filtering dust. After the entire working process is completed, the operator can pull the fixing pin 24 by the pull ring 27. The fixing pin 24 slides inside the L-shaped frame 23. This sliding process will cause the second spring 26 to deform, thus facilitating the removal of the filter frame 19. Once the fixing pin 24 is completely removed from the inside of the limit hole 28, the filter frame 19 can be completely pulled out from the inside of the box body 1. At this time, the operator can thoroughly clean the dust on the filter screen 20, effectively avoiding the performance degradation of the equipment caused by dust accumulation, and ensuring the stable operation and efficiency of the equipment.

[0035] Working principle: When using this equipment for work, send the sand and gravel aggregate into the inside of the box body 1 through the feed pipe at the top of the box body 1, and at the same time start the motor 9 to drive the rotating wheel 6 on one side to rotate. Under the action of the belt 7, the rotating wheel 6 on the other side is synchronously driven to rotate, and then the crank 4 on both sides rotates. When the crank 4 rotates, it will cause one side of the connecting plate 10 to move. At this time, the other side of the connecting plate 10 will rotate on the sliding rod 13 and lift it up at the same time, so that the pulley 14 slides on the lower surface of the push plate 3, and the push plate 3 deflects around the rotating shaft 2, thereby lifting the sand and gravel aggregate upward, causing the dust inside the sand and gravel aggregate to rise. The connecting plate 10 will move reciprocally with the rotation of the crank 4, and then the sliding rod 13 will move up and down reciprocally, achieving the effect of continuously lifting the sand and gravel aggregate. At this time, start the fan 22 again. The fan 22 will generate a suction force and suck the dust through the concave holes 18. The dust will finally be adsorbed on the filter screen 20. The sand and gravel aggregate after cleaning will finally fall on the inside of the collection box 17 along the guide plate 16. After the work is completed, pull out the collection box 17 from the inside of the box body 1 to perform subsequent processing on the collected sand and gravel aggregate. At this time, pull the fixing pin 24 to slide inside the L-shaped frame 23 through the pull ring 27, and make the second spring 26 deform. When the fixing pin 24 is removed from the inside of the limit hole 28, pull out the filter frame 19 from the inside of the box body 1 to clean the dust on the filter screen 20, avoiding the situation that excessive dust affects the use of the equipment.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
