[0002] Concrete mixing plants generate a lot of dust during operation. If the dust is not handled in time, it will not only pollute the environment, but also have a serious impact on the health of workers. In order to solve this problem, dust prevention devices are usually used to adsorb the dust. However, existing dust prevention devices often have problems such as poor adsorption effect and easy clogging of the filter screen, resulting in poor dust prevention effect and even affecting the normal operation of the concrete mixing plant.

[0035] The following is combined with Figure 1-3 This application is described in further detail.

[0036] An embodiment of the present application discloses a dust prevention device for a concrete mixing station.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A dust prevention device for a concrete mixing station includes a base 1, a mounting plate 2 vertically mounted on the base 1, and an exhaust fan 3 mounted on the base 1. A plurality of air suction ports 21 are provided on a side surface of the mounting plate 2. In the present application, the air suction ports 21 provided along the same horizontal direction are a row. The mounting plate 2 is provided with a plurality of rows of air suction ports 21 in a vertical direction. A filter screen 22 is provided at each air suction port 21. The plurality of air suction ports 21 are connected to the exhaust fan 3 through a pipeline.

[0038] The base 1 is placed in an area with much dust in the concrete mixing plant, and a negative pressure is formed at the air inlet 21 through the exhaust fan 3. The dusty air from the outside is filtered through the filter 22 and enters the air inlet 21. The dust in the air is filtered on the filter 22 and collected by personnel, thereby reducing the dust content in the air and improving the air quality in the mixing plant.

[0039] Reference Figure 1 , Figure 2 and Figure 3 In order to clean the filter 22, the dustproof device further includes a cleaning assembly 4, the cleaning assembly 4 includes a wind shield 41 disposed at the air inlet 21, the inner cavity of the wind shield 41 is connected to the air inlet 21, and the opening of the wind shield 41 faces downward;

[0040] A cleaning plate 42 is used to scrape the surface of the filter 22. The cleaning plate 42 is elastically slidably connected in the vertical direction in the wind shield 41. One side of the cleaning plate 42 abuts against the filter 22. The cleaning plate 42 separates the inner cavity of the wind shield 41 into an upper chamber 411 and a lower chamber 412. The lower chamber 412 is connected to the opening of the wind shield 41. When the cleaning plate 42 is in normal state, the upper chamber 411 is connected to the air suction port 21, and the lower chamber 412 is not connected to the air suction port 21. When the exhaust fan 3 is working, the cleaning plate 42 moves upward due to the negative pressure formed in the upper chamber 411, and the upper chamber 411 and the lower chamber 412 are both connected to the air suction port 21.

[0041] After the exhaust fan 3 stops working after a period of time, the cleaning plate 42 will scrape off the dust accumulated on the surface of the filter screen 22 during the process of returning to normal state, thereby ensuring that the filter screen 22 is unblocked.

[0042] Reference Figure 3 Furthermore, in order to facilitate the cleaning of the surface of the filter screen 22 by the cleaning plate 42, a scraper 421 is provided on the side of the lower plate surface of the cleaning plate 42 close to the filter screen 22. The cross-section of the scraper 421 is a right-angled triangle, one right-angled side coincides with the bottom wall of the cleaning plate 42, and the other right-angled side is in contact with the filter screen 22.

[0043] Reference Figure 1 and Figure 3 In order to collect the dust cleaned by the cleaning plate 42, the cleaning assembly 4 also includes a collection box 43 fixed on the mounting plate 2 and located below the wind shield 41. The upper end of the collection box 43 is open, and one collection box 43 corresponds to at least one wind shield 41. In the present application, one collection box 43 is provided below a row of air inlets 21;

[0044] In this way, the dust scraped off by the cleaning plate 42 is collected.

[0045] Refer to 1 and Figure 3 In order to prevent the dust in the collection box 43 from being blown up or scattered by the wind, a blocking plate 431 is elastically hinged at the opening of the collection box 43. In normal state, the blocking plate 431 is horizontal to block the collection opening of the collection box 43;

[0046] When the cleaning plate 42 scrapes the dust on the filter screen 22, the dust falls on the blocking plate 431, pressing the blocking plate 431 to rotate toward the collection box 43, and the dust slides from the blocking plate 431 into the collection box 43. After the dust slides down, the blocking plate 431 returns to a horizontal state.

[0047] Reference Figure 1 and Figure 3 In order to facilitate personnel to clean the collection box 43, a clamping groove 23 for placing the collection box 43 is provided on the mounting plate 2;

[0048] This makes it easy for personnel to disassemble the collection box 43 and process the dust in the collection box 43 .

[0049] Reference Figure 1 In order to facilitate the movement of the dust-proof device, a plurality of universal wheels 5 are provided below the base 1, and a plurality of support rods 6 are provided above the base 1 along its circumference. One end of the support rod 6 passes through the base 1 and slides in the vertical direction. Each support rod 6 slides on the base 1 through a driving member 7. In this application, the driving member 7 is a cylinder, and the cylinder body of the driving member 7 is fixed on the base 1. The output shaft of the driving member 7 is connected to the support rod 6;

[0050] After the personnel push the dustproof device to the desired position, the driving member 7 drives the support rod 6 to slide and contact the ground, so that the universal wheel 5 is separated from the ground, the dustproof device is fixed, and the height distance between the air inlet 21 and the dust generating position is adjusted at the same time.

[0051] Reference Figure 1 , Figure 2 and Figure 3 At the same time, a sound insulation layer 8 made of sound absorbing material is provided on the side of the mounting plate 2 away from the air inlet 21 to reduce noise at the dust generating location.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
