Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] Example: See Figure 1-5 The utility model provides a technical solution: a dust reduction device for cement product production, comprising a shell 1 and a rotating door 3 rotatably connected to the side thereof, a discharge pipe 2 is connected through the top side of the shell 1, a limiting member 4 is connected to the bottom of the inner wall of the shell 1, and a descending member 5 is connected to the top of the inner wall of the shell 1;

[0025] Furthermore, the limit member 4 is L-shaped, and four limit members 4 are provided at the bottom of the inner wall of the shell 1. The four limit members 4 are symmetrically distributed inside the shell 1. The structure of the shell 1 can wrap the concrete bag inside the shell 1, thereby eliminating the risk of dust overflow. At the same time, the device takes materials through the descending part 5, avoiding the process of dumping concrete powder, and ensuring the stability of the device.

[0026] The descending component 5 is connected with a telescopic tube 6 , the other end of the telescopic tube 6 is connected with a filter component 7 , a side of the filter component 7 is connected with a blast assembly 8 , and the blast assembly 8 is connected with the discharge pipe 2 .

[0027] The descending component 5 includes a telescopic rod 501 connected to the top of the inner wall of the shell 1, a limiting ring 502 is connected to the bottom of the telescopic rod 501, the limiting ring 502 is located directly above the limiting member 4, a lifting groove 503 is provided on the inner wall of the limiting ring 502, the limiting ring 502 is slidably connected to a sliding member 505 through the lifting groove 503, the sliding member 505 is connected to a supporting member 506, the top of the limiting ring 502 is connected to a pipe support 504, and a locking member 507 is provided on the outer side of the limiting ring 502, and the locking member 507 passes through the lifting groove 503 and is connected to the sliding member 505;

[0028] Furthermore, the locking member 507 includes a threaded rod and an anti-slip member. The threaded rod passes through the lifting groove 503 and is threadedly connected to the sliding member 505. The other end of the threaded rod is connected to the anti-slip member. The anti-slip member contacts and squeezes the outer side of the limit ring 502. Through the structure of the descending component 5, the position of the telescopic tube 6 can be lowered as the concrete is used, ensuring that the distance between the telescopic tube 6 and the top of the concrete is always fixed.

[0029] The filter component 7 includes a filter housing 701 connected to the top of the inner wall of the housing 1, a guide member 702 is connected to the top of the inner wall of the filter housing 701, two collecting buckets 703 are connected to the filter housing 701, the two collecting buckets 703 are distributed on both sides of the guide member 702, a filter screen 704 is provided on the side of the collecting bucket 703, the filter screen 704 faces the direction of the air blowing assembly 8, a through hole is provided on the side of the filter housing 701, a connecting pipe is provided on the outside of the through hole, and the filter housing 701 is connected to the air blowing assembly 8 through the connecting pipe;

[0030] Furthermore, the top of the collecting hopper 703 is inclined, and the tops of the two collecting hoppers 703 are inclined toward the direction of the guide member 702. A through hole is provided at the bottom of the filter shell 701, and the telescopic tube 6 is connected through the through hole at the bottom of the filter shell 701. A feed head is provided at the bottom of the telescopic tube 6, and the feed head is connected to the pipe bracket 504. The structure of the filtering component 7 can effectively improve the screening effect of the device, so that the stones in the concrete can be separated into the collecting hopper 703 during the feeding process, thereby avoiding blockage of the blowing assembly 8.

[0031] The device can effectively improve the utilization efficiency of concrete raw materials. Compared with the traditional concrete device with pouring feeding method, the device can avoid concrete splashing by suction and facilitate the control of concrete discharging speed.

[0032] When the device is in working state, the concrete raw material bag can be placed inside the shell 1 through the rotating door 3, and the position of the concrete raw material bag can be limited by the structure of the limiter 4 to ensure that the concrete raw material bag is accurately positioned. At this time, the top of the concrete raw material bag is unsealed and opened, and the top of the concrete raw material bag is placed inside the limit ring 502 and then the rotating door 3 is closed.

[0033] After the concrete raw material bag is placed, the height of the sliding member 505 is adjusted according to different types of concrete raw materials. The locking effect of the locking member 507 is unlocked by rotation, so that the sliding member 505 can slide inside the lifting groove 503, thereby adjusting the height of the abutment member 506. After the adjustment is completed, the limiting ring 502 is loosened, so that the abutment member 506 contacts the top of the concrete raw material bag. At this time, the limiting ring 502 covers the top of the concrete raw material bag.

[0034] By adjusting the height of the sliding member 505, the effect of changing the distance between the bottom of the telescopic tube 6 and the concrete can be achieved. After the adjustment of the sliding member 505 is completed, the blowing assembly 8 is started. At this time, a negative pressure airflow is generated by the blowing assembly 8. Driven by the airflow, the concrete flows upward and enters the interior of the filter shell 701.

[0035] Through the guiding effect of the guide member 702, the concrete can be guided to both sides, so that the concrete enters the collecting bucket 703. The concrete can be screened and filtered through the filter net 704 inside the collecting bucket 703, so that large-diameter particles are retained inside the collecting bucket 703, thereby achieving a screening effect on the concrete.
