[0002] Concrete solid bricks are made of cement, aggregate, admixtures and additives as needed, which are mixed with water, molded and cured. They are mainly used for wall construction.

[0003] The aggregates and admixtures here are all in powder form, so a large amount of smoke and dust will be generated during mixing, which will affect people's health after inhalation. Therefore, in order to ensure a safe working environment for the staff, a smoke and dust prevention device is required during the mixing process; the smoke and dust prevention devices currently on the market all have a dust cover 2 above the mixer, and then the dust cover 2 is connected to a vacuum pump; when the vacuum pump is working, the smoke and dust in the mixer will be sucked away; but the smoke and dust will adhere to the surface of the dust cover 2, so it needs to be cleaned regularly.

[0004] The Chinese utility model patent with application number CN202122146306.6 provides a self-cleaning dust hood, which controls the electromagnet to be constantly powered on and off through a controller. The electromagnet attracts and releases the magnetic component, and the spring support assembly can make the screen move up and down and generate vibration, thereby causing the tobacco leaf fragments adsorbed on the screen to fall off, thereby achieving self-cleaning;

[0005] However, the screen cannot filter out all the smoke and dust, and some smoke and dust will still adhere to the dust cover 2, so the device provides a new cleaning method to clean the smoke and dust attached to the dust cover 2. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] See also Figure 1-6 This is an embodiment of the utility model of a smoke and dust prevention device for concrete brick making.

[0031] It includes a dust cover 2 arranged on a concrete brick mixer 1; a cleaning device 3 is arranged on the inner wall of the dust cover 2, and the cleaning device 3 includes a cleaning strip 4 and a driving device 5 for driving the cleaning strip 4 to move; the driving device 5 includes a rotating ring 51 installed on the inner wall of the dust cover 2, and a helical gear ring 52 is arranged on the rotating ring 51, and a helical gear 53 is meshed on the helical gear ring 52, and the helical gear 53 is driven by a rotating shaft 54, and a motor 55 is connected to the end of the rotating shaft 54; the cleaning strip 4 is fixed on the helical gear ring 52.

[0032] When preparing concrete bricks, cement, aggregates, and admixtures and additives as needed need to be added to the concrete brick mixer 1, and stirred with water; when adding aggregates, admixtures and other materials, the concrete brick mixer 1 will generate a large amount of dust, so a dust cover 2 is used to cover the top of the concrete brick mixer 1, and then the generated dust is extracted by a vacuum pump.

[0033] When the dust cover 2 is in use, since it is in contact with dust, the dust will likely adhere to the surface of the dust cover 2. Over time, a thick layer of dust will form on the dust cover 2, so the dust cover 2 needs to be cleaned.

[0034] In order to facilitate the cleaning of the dust cover 2, the device is designed with a new cleaning device 3, which includes a cleaning bar 4, which can clean the inner wall of the dust cover 2; at the same time, the device is provided with a driving device 5, through which the cleaning bar 4 can be automatically cleaned;

[0035] The driving device 5 includes a rotating ring 51 mounted on the inner wall of the dust cover 2, a helical gear ring 52 is provided on the rotating ring 51, a helical gear 53 is meshed on the helical gear ring 52, the helical gear 53 is driven by a rotating shaft 54, and a motor 55 is connected to the end of the rotating shaft 54; the cleaning strip 4 is fixed on the helical gear ring 52;

[0036] The process of automatic cleaning is as follows: the motor 55 is started, driving the rotating shaft 54 ​​to rotate, and the rotating shaft 54 ​​drives the bevel gear 53 to rotate; then due to the setting of the rotating ring 51, the bevel gear 53 will drive the meshing bevel gear ring 52 to rotate, and the bevel gear ring 52 can then drive the cleaning strip 4 to rotate, and the rotating cleaning strip 4 can realize automatic cleaning of the dust cover 2; it is very convenient.

[0037] The device takes into account that the size of the concrete brick mixer 1 is large, so the dust cover 2 will also be large, so the length of the cleaning strip 4 needs to be very long, but the very long cleaning strip 4 will generate friction when cleaning the dust. If too much dust accumulates at a certain place on the friction dust cover 2, a bulge will be formed. When the cleaning strip 4 brushes over the bulge, it will cause the cleaning strip 4 to deform. In order to avoid this situation, the device is also provided with a stabilizing device 6 on the inner wall of the dust cover 2;

[0038] The stabilizing device 6 includes a stabilizing ring 61, on which a stabilizing ring groove 62 is provided. One end of the cleaning strip 4 is slidably arranged in the stabilizing ring groove 62. When the cleaning strip 4 rotates, the other end is restricted in the stabilizing ring groove 62. With such a configuration, the cleaning strip 4 can still be closely attached to the inner wall of the dust cover 2 when it is deformed.

[0039] The dust cover 2 of the device is trumpet-shaped as a whole, and the cleaning strip 4 includes a mounting strip 41 and a cleaning brush 42 arranged on the mounting strip 41, and the cleaning brush 42 contacts the dust cover.

[0040] This is the most commonly used shape of dust cover 2 in the field, and the cleaning strip 4 of the device is also arranged based on the shape of the dust cover 2; the cleaning strip 4 includes a mounting strip 41 and a cleaning brush 42 arranged on the mounting strip 41, and the mounting strip 41 is used to install the cleaning brush 42. At the same time, in order to prevent deformation, the mounting strip 41 is made of alloy steel.

[0041] The dust cover 2 includes a mounting portion 21 and a cover body 22 . The mounting portion 21 is provided with a mounting groove 23 . The bevel gear 53 is disposed in the mounting groove 23 . The rotating ring 51 is mounted at the lower end of the mounting portion 21 .

[0042] The function of the mounting portion 21 is to install components that allow the cleaning strip 4 to rotate, among which the bevel gear 53 is one of them. A mounting groove 23 is provided in the device to install the bevel gear 53 and make the bevel gear 53 mesh with the bevel gear ring 52; the rotating ring 51 is to facilitate the rotation of the bevel gear ring 52, thereby driving the cleaning strip 4.

[0043] The dust cover 2 is provided with an air exhaust port 24 at the upper end and an air inlet 25 at the lower end, and the air exhaust port 24 is located in the mounting portion 21, and the air inlet 25 is located in the cover body 22; the air exhaust port 24 is connected to an air exhaust pipe 7, and the air exhaust pipe 7 adopts one of the corrugated pipes.

[0044] The exhaust port 24 is the outlet of the smoke, and the air inlet 25 is the inlet of the smoke. In order to facilitate the entry of the smoke, the diameter of the air inlet 25 is made very large, enough to cover the concrete brick mixer 1, while the exhaust port 24 has a smaller diameter, which is convenient for increasing the speed of the smoke and allowing the smoke to quickly enter the exhaust pipe 7; the exhaust pipe 7 in this device adopts a corrugated pipe, which can facilitate the movement of the entire equipment.

[0045] The stabilizing device 6 is disposed at the air inlet 25 ; this arrangement is to improve the stability of the cleaning strip 4 , while allowing the cleaning strip 4 to clean the entire inner wall of the dust cover 2 .

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
