Description

Technical Field

[0001] This utility model relates to the field of dust collection and treatment technology, specifically a dust collection and treatment device for the production of waterproof membrane. Background Technology

[0002] The dust generated during the production of waterproof membrane mainly comes from the asphalt heating, stirring, and coating processes. This dust contains a large amount of particulate matter and volatile organic compounds, which are extremely harmful to human health. Therefore, the primary purpose of dust collection and treatment is to reduce the emission of these harmful substances and protect the environment and public health. The commonly used dust treatment device is a spray tower, which removes particulate matter and some harmful gases from the dust through spraying.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN220715355U) discloses a flue gas treatment spray device, including a fixed box. A spray housing is mounted on the top outer wall of the fixed box, and a top cover is mounted on the top outer wall of the spray housing. Connectors are integrally formed on the bottom outer wall of both the top cover and the bottom outer wall of the spray housing. Connecting grooves are formed on the top outer wall of both the spray housing and the top outer wall of the fixed box, and the connectors are inserted into these grooves. Fixing grooves are formed on the top outer walls of both the spray housing and the fixed box, and sealing gaskets are adhered to the inside of these grooves. Two spray pipes are inserted into the inside of the spray housing, and several nozzle bodies are threaded onto one side of the outer wall of each spray pipe. This utility model, through its spray housing and connecting heads, facilitates the installation and disassembly of the spray device during use, thereby improving the efficiency of installation and maintenance.

[0004] Although the aforementioned patent can achieve maintenance of the spraying device, the particulate matter removed by the spraying still remains at the bottom of the spraying tower, making it inconvenient to collect and clean the sediment particles at the bottom of the tower, thereby reducing the convenience of subsequent maintenance.

[0005] Therefore, this utility model provides a dust collection and treatment device for the production of waterproof membranes to solve the above problems. Utility Model Content

Detailed Implementation

[0027] 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.

[0028] like Figure 1-4As shown, this utility model provides a dust collection and treatment device for the production of waterproof membrane rolls, including a spray tower body 1, an air inlet 11 penetrating one side of the spray tower body 1, a filter screen 12 fixedly connected to the inner wall of the spray tower body 1, a drain pipe 13 fixedly connected to the bottom of the filter screen 12, a first motor 14 fixedly connected to one end of the drain pipe 13 extending to the outside of the spray tower body 1, an auger 15 fixedly connected to the output end of the first motor 14, and the auger 15 rotatably disposed inside the drain pipe 13; a cleaning assembly 2, for cleaning... The cleaning component 2 is installed inside the spray tower body 1, and the cleaning component 2 is used to clean and scrape the inner wall of the filter screen 12. When the smoke and dust gas mixture enters the spray tower body 1 through the air inlet 11, it reacts with the harmful gases such as particulate matter through the spraying of the liquid inside the spray tower body 1. The particulate matter that falls and settles to the filter screen 12 is guided by the filter screen 12 and collected into the drain pipe 13. The first motor 14 drives the auger 15 to rotate, thereby realizing the discharge of the collected particulate matter.

[0029] Furthermore, the bottom of the filter screen 12 is integrally and fixedly connected to the feed pipe of the drain pipe 13. The filter screen 12 has a conical funnel-shaped structure. The funnel-shaped structure can guide the sedimented particles and improve the convenience of collecting the sedimented particles. The drain pipe 13 has a drain port 16 at the bottom of one end that extends to the outside of the spray tower body 1. The bottom of the drain port 16 is connected to a control ball valve. By installing a ball valve at the bottom of the drain port 16, sealing control can be achieved.

[0030] Furthermore, the cleaning assembly 2 includes a second motor 21, which is fixedly connected to the outer wall of the spray tower body 1. A main shaft 22 is fixedly connected to the output end of the second motor 21, and a first bevel gear 23 is fixedly connected to the other end of the main shaft 22. A second bevel gear 24 meshes with the outer side of the first bevel gear 23. A drive shaft 25 is fixedly connected to the center of the second bevel gear 24. Bearing brackets 29 are connected to both the upper and lower ends of the drive shaft 25, and the bearing brackets 29 are fixedly connected to the inner wall of the filter screen 12. Connecting members 26 are fixedly connected to both the upper and lower ends of the outer wall of the drive shaft 25, and the connecting members 26 are also connected to the outer side of the filter screen 12. A positioning plate 27 is fixedly connected to one end, and a scraper 28 is fixedly connected to the other side of the positioning plate 27. The other side of the scraper 28 is attached to the surface of the filter screen 12. When the second motor 21 is driven, the first bevel gear 23 is driven to rotate through the main shaft 22. Furthermore, the meshing of the first bevel gear 23 and the second bevel gear 24 drives the transmission shaft 25 to rotate. The scraper 28 is driven to rotate through the connection of the connector 26 and the positioning plate 27. While the scraper 28 is rotating, it scrapes off the particles on the surface of the filter screen 12 and guides the particles to the inside of the drain pipe 13.

[0031] Furthermore, the drive shaft 25 and the filter screen 12 are coaxially distributed, and two connecting parts 26 are located between two bearing brackets 29. The outer wall of the drive shaft 25 is fixedly connected with a first guide cone 3 and a second guide cone 31. The upper surfaces of the first guide cone 3 and the second guide cone 31 are both conical. The first guide cone 3 is located above the second bevel gear 24 and the first bevel gear 23, and the diameter of the first guide cone 3 is larger than the distribution diameter of the second bevel gear 24 and the first bevel gear 23. The second guide cone 31 is located above the lower bearing bracket 29. Through the arrangement of the first guide cone 3 and the second guide cone 31, the rotational connection between the bearing bracket 29 and the drive shaft 25 is covered and protected to prevent falling particles from contacting it and to improve the smoothness of the rotation of the drive shaft 25.

[0032] Working principle: When the flue gas enters the spray tower 1 through the air inlet 11, the particulate matter inside the flue gas reacts and settles to the bottom of the spray tower 1 through the spraying of liquid. At the same time, the conical structure of the filter screen 12 guides the settled particulate matter to the drain pipe 13. When it is necessary to clean the sediment, the drain port 16 is opened, and the first motor 14 drives the auger 15 to rotate, which can guide the sediment in the drain pipe 13 and the filter screen 12 to be discharged. At the same time, the second motor 21 drives the scraper 28 to rotate through the transmission of the first bevel gear 23 and the second bevel gear 24, which can scrape the surface of the filter screen 12, improve the smoothness of the sediment flow into the drain pipe 13, and avoid the residue of particulate matter on the surface of the filter screen 12, which may cause blockage.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
