[0002] Graded processing of manufactured sand helps improve the quality of aggregates and meets the needs of different projects. The production process of manufactured sand generates a large amount of dust, which not only pollutes the environment but may also affect the normal operation of equipment. Therefore, dust removal devices are needed to effectively reduce dust emissions and ensure production safety and environmental protection.

[0003] However, existing dust removal devices for manufactured sand grading have shortcomings. First, existing dust removal devices often use filters to filter the sand and dust drawn in, but after long-term operation, the surface of the filters is easily clogged by sand and dust particles, affecting the normal operation of the dust removal device. Second, the sand and dust filtered out by the dust removal device is not easy to clean and discharge. Therefore, a dust removal device for manufactured sand grading is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dust removal device for graded treatment of manufactured sand. It aims to improve the existing dust removal devices that often use filters to filter the sand and dust that are drawn in. However, after long-term operation, the surface of the filter screen is easily blocked by sand and dust particles, which affects the normal operation of the dust removal device and makes it difficult to clean and discharge the sand and dust filtered out of the dust removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dust removal device for graded processing of manufactured sand, comprising a cylinder, an air inlet pipe fixedly connected to the bottom of one side of the cylinder, a fan fixedly installed at the top of the other side of the cylinder, an annular seat installed at the top of the inner wall of the cylinder, a mesh frame installed inside the annular seat, a filter screen fixedly connected to the bottom of the mesh frame, a vibration motor fixedly installed at the top of both sides of the inner wall of the mesh frame, a support assembly installed on the inner wall of the annular seat, a spray assembly installed in the middle of the inner wall of the cylinder, and a cleaning assembly installed at the top of the cylinder;

[0006] The support assembly includes a slip ring and several springs. The slip ring is fixedly sleeved on the side wall of the mesh frame and slidably connected to the inner wall of the annular seat. Several springs are fixedly connected to the top and bottom of the slip ring, and one end of each spring is fixedly connected to the upper and lower ends of the inner wall of the annular seat.

[0007] As a further description of the above technical solution:

[0008] The spray assembly includes an annular pipe and several atomizing nozzles. The annular pipe is fixedly connected to the middle of the inner wall of the cylinder, and several atomizing nozzles are uniformly fixedly connected to the bottom of the annular pipe.

[0009] As a further description of the above technical solution:

[0010] The cleaning assembly includes a geared motor, a vertical shaft, and two scraper frames. The geared motor is fixedly installed in the middle of the top of the cylinder. The output end of the geared motor passes through the cylinder and is fixedly connected to the vertical shaft. A through hole is opened in the middle of the filter screen. The bottom end of the vertical shaft passes through the through hole and is fixedly connected to two scraper frames.

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

[0012] One end of the air intake pipe is fixedly connected to a dust suction hood, and the input end of the fan is connected to the inside of the cylinder.

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

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, a spray assembly is installed in the dust removal equipment to transport water into the annular pipe and spray it out from several atomizing nozzles. This causes larger sand and dust particles to combine with water and form a settling effect, which can reduce the filtration pressure of the subsequent filter screen. By periodically starting the vibration motor, with the support of the slip ring and spring, the filter screen can be driven to vibrate at a large amplitude, thereby shaking off the sand and dust particles attached to its bottom surface and playing a clearing role. This can prevent the filter screen from clogging and affecting the normal operation of the dust removal device.

[0023] 2. In this utility model, the sand and dust particles and spray water that fall during dust suppression will fall to the bottom of the cylinder. Similarly, the sand and dust particles shaken off when the filter screen vibrates will also fall to the bottom of the cylinder. By opening the butterfly valve, sewage and filtered materials can be quickly discharged from the drain pipe. During this process, the reduction motor on the cleaning component is started, which drives the scraper at the bottom of the vertical shaft to rotate, which can scrape off the sand and dust adhering to the bottom of the inner wall of the cylinder, thus improving the cleaning effect.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-4An embodiment of this utility model provides a dust removal device for graded processing of manufactured sand, comprising a cylinder 1, an air inlet pipe 2 fixedly connected to the bottom of one side of the cylinder 1 for inputting gas containing sand and dust, a fan 4 fixedly installed on the top of the other side of the cylinder 1 to attract dust from the grading equipment using negative pressure, an annular seat 7 installed on the top of the inner wall of the cylinder 1, a mesh frame 9 installed inside the annular seat 7, a filter screen 11 fixedly connected to the bottom of the mesh frame 9 for filtering sand and dust particles in the gas, a vibration motor 12 fixedly installed on the top of both sides of the inner wall of the mesh frame 9 to drive the filter screen 11 to vibrate and play a role in unblocking, a support component installed on the inner wall of the annular seat 7 to support the mesh frame 9, a spray component installed in the middle of the inner wall of the cylinder 1 to play a role in spraying and dust suppression, and a cleaning component installed at the top of the cylinder 1 to clean the sand and dust particles adhering to the bottom of the inner wall of the cylinder 1.

[0032] Reference Figure 3 The support assembly includes a slip ring 8 and several springs 10. The slip ring 8 is fixedly sleeved on the side wall of the mesh frame 9 and slidably connected to the inner wall of the annular seat 7, so that the mesh frame 9 can slide up and down relative to the annular seat 7. Several springs 10 are fixedly connected to the top and bottom of the slip ring 8, and one end of each spring 10 is fixedly connected to the upper and lower ends of the inner wall of the annular seat 7, respectively, to provide support. This allows the vibrating motor 12 to drive the filter screen 11 to vibrate at a large amplitude after it is started, thereby shaking off the sand and dust particles attached to its bottom surface.

[0033] Reference Figure 2 The spray assembly includes an annular pipe 14 and several atomizing nozzles 15. The annular pipe 14 is fixedly connected to the middle of the inner wall of the cylinder 1. Several atomizing nozzles 15 are uniformly fixedly connected to the bottom of the annular pipe 14, so that water is transported into the annular pipe 14 and sprayed out from the several atomizing nozzles 15, so that larger sand and dust particles combine with water to form a settling effect.

[0034] Reference Figure 2 and Figure 4 The cleaning assembly includes a geared motor 17, a vertical shaft 18, and two scraper frames 19. The geared motor 17 is fixedly installed in the middle of the top of the cylinder 1 and serves as a drive. The output end of the geared motor 17 passes through the cylinder 1 and is fixedly connected to the vertical shaft 18. A through hole 20 is opened in the middle of the filter screen 11. The bottom end of the vertical shaft 18 passes through the through hole 20 and is fixedly connected to two scraper frames 19. The geared motor 17 drives the scraper frames 19 at the bottom of the vertical shaft 18 to rotate, which can scrape off the sand and dust adhering to the bottom of the inner wall of the cylinder 1 and improve the cleaning effect.

[0035] Reference Figure 1One end of the air inlet pipe 2 is fixedly connected to a dust suction hood 3. The input end of the fan 4 is connected to the inside of the cylinder 1. The dust suction hood 3 is connected to the crushing or screening equipment for the graded processing of manufactured sand. By starting the fan 4, the dust generated during the operation of the equipment can be sucked into the cylinder 1. The sand and gravel particles will be dusted and filtered, while the sucked-in gas will be discharged from the output end of the fan 4.

[0036] Reference Figure 2 A drain pipe 5 is fixedly connected to the middle of the bottom end of the cylinder 1. A butterfly valve 6 is installed in the middle of the drain pipe 5. After opening the butterfly valve 6, the sewage and filter material at the bottom of the cylinder can be quickly discharged from the drain pipe 5.

[0037] Reference Figure 1 and Figure 2 A water inlet connector 16 is fixedly connected to the middle of the front side of the cylinder 1, and one end of the water inlet connector 16 is connected to the inside of the annular pipe 14. The water inlet connector 16 can be connected to an external water supply pipe to deliver the spray water to the annular pipe 14.

[0038] Reference Figure 2 The bottom of the scraper 19 is in contact with the bottom of the inner wall of the cylinder 1. When the scraper 19 rotates, it can scrape the sand and dust particles attached to the bottom of the inner wall of the cylinder 1 to prevent them from being unable to be discharged with the water flow.

[0039] Reference Figure 1 Both ends of the bottom of the cylinder 1 are fixedly connected to the brackets 13, which support and elevate the cylinder 1 to facilitate the operation of the dust removal device.

[0040] Working principle: The dust collection hood 3 of this dust removal device is connected to the crushing or screening equipment for graded manufactured sand. By starting the fan 4, the dust generated during the operation of the equipment is sucked into the cylinder 1 through the air inlet pipe 2. A spray assembly is installed inside the dust removal device, and a water supply pipe is connected to the water inlet connector 16 to deliver water to the annular pipe 14 and spray it out from several atomizing nozzles 15. This causes larger sand and dust particles to combine with water and form a settling effect, which reduces the filtration pressure of the subsequent filter screen 11. The filter screen 11 then further filters the fine sand and dust particles, while the sucked-in air is discharged from the output end of the fan 4. This process is repeated periodically. The vibrating motor 12, supported by the slip ring 8 and the spring 10, can drive the filter screen 11 to vibrate at a large amplitude, thereby shaking off the sand and dust particles attached to its bottom surface and playing a role in unblocking. This can prevent the filter screen 11 from becoming clogged and affecting the normal operation of the dust removal device. The sand and dust particles and spray water that fall during dust suppression will fall to the bottom of the cylinder. Similarly, the sand and dust particles shaken off by the filter screen 11 will also fall to the bottom of the cylinder. By opening the butterfly valve 6, sewage and filtered materials can be quickly discharged from the drain pipe 5. During this period, the reduction motor 17 on the cleaning and scraping assembly is started, which drives the scraper 19 at the bottom of the vertical shaft 18 to rotate, which can scrape off the sand and dust adhering to the bottom of the inner wall of the cylinder 1 and improve the cleaning effect.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
