Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a dust removal device for concrete production. Background Technology

[0002] Concrete production refers to the process of metering and feeding raw materials such as sand, gravel, cement, and fly ash according to the construction mix ratio, and then mixing them to form concrete products. During the feeding and mixing process, a large amount of particulate dust is generated, which seriously pollutes the outside air. Therefore, a dust removal device for concrete production is needed.

[0003] Existing dust removal equipment typically involves setting up mobile dust collectors within the factory area to focus on dust removal in contaminated areas. This type of dust removal covers a large area, and the dust is dispersed in all directions by the airflow, resulting in low efficiency of the dust removal equipment.

[0004] According to CN218459053U, this utility model discloses a dust removal device for concrete production, including a base, a dust collection box, and a dust collection box mounted on the base. Symmetrical longitudinal columns are arranged at one end of the base, and a lifting mechanism is provided between the two columns. The lifting mechanism includes a lifting drive mounted on the base, a placement plate mounted on the top of the lifting drive, and sliders at both ends of the placement plate. The sliders can slide up and down within grooves formed on the columns. A placement groove is provided on the top surface of the placement plate, and a clamp is provided on the placement groove to fix the dust inlet hose within the placement groove. This utility model, through the setting of the lifting mechanism, allows the dust collection hood to be aligned with the upper port of the concrete mixing drum, effectively preventing dust from flying out during mixing and greatly reducing dust pollution.

[0005] According to the dust removal device for concrete production described above, the dust suction hood can be aligned with the upper end of the concrete mixing drum through the setting of the lifting mechanism, thereby achieving the effect of treating the dust generated during mixing. However, the overall operation is complicated and not conducive to the operation of workers. Therefore, we need to propose a dust removal device for concrete production. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-4 This utility model provides a dust removal device for concrete production, including a tank assembly 1, a filter assembly 2 installed on the top of the tank assembly 1, a water supply assembly 3 connected to the outside of the tank assembly 1, and a dust-reducing mixing assembly 4 installed inside the tank assembly 1. The tank assembly 1 includes a tank body 11, and a feed hopper 12 is installed through the top of the tank body 11. The filter assembly 2 includes a blower 21 fixedly installed on the top of the tank body 11. The air inlet end of the blower 21 is connected to a first exhaust pipe 22. The air inlet end of the first exhaust pipe 22 is connected to a filter box 23. One end of the filter box 23 is connected to a second exhaust pipe 26. The air inlet end of the second exhaust pipe 26 is connected to a dust collection hood 27. The opening end of the dust collection hood 27 is close to the left side of the feed hopper 12.

[0024] In use, by setting the filter assembly 2, the blower 21 is started, and the airflow carries the dust from the feed hopper 12 into the dust collection hood 27, and then into the filter box 23 through the second exhaust pipe 26. The dust is finally adsorbed by the filter plate 25 inside the filter box 23, and the filtered gas is discharged from the exhaust end of the blower 21 through the first exhaust pipe 22, achieving the effect of filtering and treating dust from the source. With the setting of the water supply assembly 3, the water supply for concrete production is met while reducing the dust generated by mixing.

[0025] The bottom of the tank 11 is conical to achieve rapid discharge of concrete. The bottom of the tank 11 is equipped with an automatic discharge port 13, which allows the produced concrete to be discharged as required.

[0026] The top of the filter box 23 has several sets of concave grooves 24, and a set of filter plates 25 are inserted inside each set of concave grooves 24. The connection between the filter plates 25 and the concave grooves 24 makes it convenient to replace or clean the filter plates 25.

[0027] The water supply assembly 3 includes a water tank 31, one end of which is connected to a booster pump 32. The drain end of the booster pump 32 is connected to a water supply pipe 33. The drain end of the water supply pipe 33 is connected to the top of the outer side of the tank body 11. Through the connection between the water tank 31, the booster pump 32, and the water supply pipe 33, the water supply to the inside of the tank body 11 is achieved, thus meeting the requirements of concrete production.

[0028] The water supply pipe 33 is located inside the tank 11 and is connected to a circular pipe 34 at one end. Several sets of spray holes 35 are opened on one side of the circular pipe 34. By utilizing the connection between the circular pipe 34 and the water supply pipe 33, the water flows out through the circular pipe 34, making the water flow more uniform.

[0029] The outer side of the circular tube 34 is fixedly connected to the inner wall of the tank body 11. The water spraying direction of several sets of spray holes 35 is all towards the center. Through the setting of several sets of spray holes 35, a water curtain net will be formed above the concrete, thereby achieving the effect of dust suppression and avoiding a large amount of dust rising.

[0030] The stirring assembly 4 includes a servo motor 41 fixedly installed on the top of the tank 11. The output shaft of the servo motor 41 is keyed to a rotating rod 42. The outer arc surface of the rotating rod 42 is rotatably connected to the top of the tank 11. Several sets of blades 43 are fixedly installed on the outer arc surface of the rotating rod 42 inside the tank 11. When the servo motor 41 is started, the rotating rod 42 is driven to rotate, and the rotating rod 42 drives the blades 43 to rotate, thereby achieving the effect of stirring the raw materials inside the tank 11.

[0031] In practical use: Various raw materials for concrete production are fed into the tank 11 through the feed hopper 12. At this time, a large amount of dust will be generated. The blower 21 of the filter assembly 2 is started. The airflow carries the dust from the feed hopper 12 into the dust collection hood 27, and then into the filter box 23 through the second exhaust pipe 26. The dust is finally adsorbed by the filter plate 25 inside the filter box 23. The filtered gas is discharged from the exhaust end of the blower 21 through the first exhaust pipe 22, achieving the effect of filtering and treating dust from the source. The water supply assembly 3 and the mixing assembly 4 are started at the same time. The water curtain is used to reduce the dust generated during mixing and meet the water supply requirements during concrete production. When the water supply ratio meets the requirements, the water supply assembly 3 is turned off. At this time, no more dust will be generated when mixing concrete. The above device improves the dust removal efficiency and is easy to operate.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
