Description

Technical Field

[0001] This utility model relates to the field of zinc oxide production equipment, and more particularly to a dust collection device used in zinc oxide production. Background Technology

[0002] Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints, ointments, flame retardants, and other products. In the zinc oxide production process, the raw material is generally derived from zinc ore. Since zinc ore raw materials vary in size, a crushing process is required before actual production. Dust is inevitably generated during the crushing process. Therefore, dust collection equipment is usually installed next to the production equipment to reduce on-site dust pollution. For example, a zinc oxide dust collection device for zinc oxide production (publication number CN222220650U) disclosed on the China Patent Network uses an absorption mechanism to suck dust into a collection tank and onto a filter screen. A scraping component scrapes the dust accumulated on the filter screen, achieving an automatic scraping effect. The screened zinc oxide powder falls into the hopper through the gaps in the filter screen, facilitating material discharge.

[0003] However, the aforementioned disclosed patents and existing zinc oxide dust collection devices in the market still have some shortcomings: While existing methods using scraping components to clean and discharge dust accumulated on the filter screen have good dust collection characteristics, they are limited by their upper-layer scraping cleaning capabilities. Dust often adheres to the filter screen under gravity, failing to achieve thorough cleaning and easily becoming trapped and clogged, thus compromising the filter's dust collection performance. Therefore, those skilled in the art have provided a dust collection device for zinc oxide production to address the problems mentioned in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dust collection device for zinc oxide production, which solves the problem that the dust collection performance of existing zinc oxide dust collection devices mentioned in the background art cannot be guaranteed for a long time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust collection device for zinc oxide production, comprising: a filter tank containing a filter screen; an air inlet box located above the filter tank, the air inlet box having an exhaust pipe connected to the filter screen; a collection tank located below the filter tank, the collection tank containing at least one set of baffles; and a brake shaft extending through the filter tank and the air inlet box into the collection tank, the brake shaft having an air intake fan with a built-in air inlet box, a cleaning brush with a built-in filter screen, and a material-pushing rod for pressing the baffles.

[0006] As a further technical solution of this utility model: the filter cylinder is a conical cylinder structure.

[0007] As a further technical solution of this utility model: the brake shaft is provided with at least one set of support arms along its axial direction, the support arms support the cleaning brush plate, and the cleaning brush plate is provided with soft bristles that fit against the filter screen cylinder.

[0008] As a further technical solution of this utility model: the baffle is provided in multiple groups, and the two adjacent groups of baffles are arranged in an alternating manner.

[0009] As a further technical solution of this utility model: the number of the material-pulling rods is the same as the number of the material-blocking plates, and the material-pulling rods are symmetrically arranged and flatly pressed onto the surface of the material-blocking plates.

[0010] As a further technical solution of this utility model: the brake shaft is provided with a stirring paddle along its axial direction, which is directly opposite the bottom of the collection tank.

[0011] As a further technical solution of this utility model: the body of the filter tank is provided with an exhaust pipe directly above the filter screen cylinder.

[0012] As a further technical solution of this utility model: the air intake box is provided with a brake motor that drives the brake shaft.

[0013] As a further technical solution of this utility model: the air inlet of the air inlet box is connected to an air inlet pipe, the other end of the air inlet pipe is connected to a telescopic pipe, and the other end of the telescopic pipe is connected to an air suction pipe.

[0014] As a further technical solution of this utility model: the telescopic tube includes a telescopic flexible tube disposed between the air inlet pipe and the air intake pipe, and the telescopic flexible tube is provided with a long screw bolted to the air inlet pipe and the air intake pipe along its circumference.

[0015] This invention provides a dust collection device for zinc oxide production, which has the following advantages compared with the prior art:

[0016] 1. The zinc oxide dust collection device designed in this paper uses a combination of a brake motor and a brake shaft as the driving source. On the one hand, it drives the intake fan to operate, drawing dusty air from the outside through the intake box into the filter canister. The filter screen inside the filter canister filters the dusty air in a reverse filtration manner, allowing the filtered dust to accumulate in the collection canister under gravity. On the other hand, it drives the combination of the support arm and the cleaning brush to rotate, brushing away the residual dust on the filter screen. It has good dust self-collection characteristics, ensuring efficient dust collection performance while avoiding dust blockage and accumulation.

[0017] 2. The zinc oxide dust collection device designed in this paper is based on the staggered arrangement of baffles inside the collection tank to carry the dust. Driven by a combination of a brake motor and a brake shaft, the material-pushing rod rotates, sequentially and staggeredly pushing the dust on the baffles to the bottom of the collection tank. This achieves a stepped collection of dust, while the staggered baffles prevent dust from splashing back and scattering under wind force, ensuring the stability of dust collection.

[0018] 3. The zinc oxide dust collection device designed in this paper is based on a drive source formed by the combination of a brake motor and a brake shaft. It has good integrated drive characteristics and can perform integrated adsorption, dust removal filtration, and collection of zinc oxide dust. Its equipment structure is compact, more practical, and more efficient and timely in collecting dust. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example 1:

[0027] Please see Figure 1-5 This utility model provides a technical solution for a dust collection device used in zinc oxide production: The dust collection device for zinc oxide production includes a filter tank 1, inside which is a filter screen cylinder 11. The filter screen cylinder 11 has a conical structure and is located above an air inlet box 2. The exhaust port of the air inlet box 2 is equipped with an exhaust pipe 10 that is conductively connected to the filter screen cylinder 11. A brake motor 7 driving a brake shaft 14 is mounted on the air inlet box 2. The brake shaft 14 passes through the filter tank 1 and the air inlet box 2, extending into the interior of a collection tank 3. An intake fan 9 with an internal air inlet box 2 is mounted on the brake shaft 14. A cleaning brush 16 with an internal filter screen cylinder 11 is also mounted on the brake shaft 14. The device is controlled by the brake motor... When the machine 7 is working, it drives the brake shaft 14 to rotate. On one hand, it drives the intake fan 9 to work, drawing dusty air from the outside into the intake box 2 and guiding it to the filter canister 1 through the exhaust pipe 10. When the dusty air flows in the filter canister 1, the inner cylinder of the filter screen 11 filters the dusty air, filtering the dusty air in a reverse filtration manner. The filtered dust accumulates in the collection canister 3 under the action of gravity. On the other hand, it drives the cleaning brush plate 16 to rotate, brushing and cleaning the residual dust on the inner cylinder of the filter screen 11, ensuring its efficient filtration and insect removal characteristics. It has good dust self-collection characteristics, while avoiding dust blockage and accumulation.

[0028] As a further embodiment of this invention, the filter tank 1 is provided with an exhaust pipe 8 directly above the filter screen cylinder 11. The exhaust pipe 8 allows the dusty air to be circulated and discharged to the outside after being filtered by the filter screen cylinder 11.

[0029] Furthermore, the brake shaft 14 is provided with at least one set of support arms 15 along its axial direction. The support arms 15 support the cleaning brush plate 16. The cleaning brush plate 16 is provided with soft bristles that fit against the filter screen cylinder 11. By using the arm force of the support arms 15 to support the cleaning brush plate 16, it rotates synchronously with the brake shaft 14. The soft bristles on the brush plate are used to brush and clean the inner cylinder of the filter screen cylinder 11 to ensure the high-efficiency filtration and dust removal characteristics of the filter screen cylinder 11. Example 2:

[0030] Please see Figure 2-5This embodiment further explains Example 1. The collection tank 3 is located below the filter tank 1. The collection tank 3 is equipped with at least one set of baffle plates 12. Multiple sets of baffle plates 12 are provided, with adjacent sets of baffle plates 12 arranged in an alternating pattern. The brake shaft 14 is equipped with a push rod 17 that flattens the baffle plates 12. The number of push rods 17 is the same as the number of baffle plates 12, and the push rods 17 are symmetrically arranged, flattening the surface of the baffle plates 12. Through the alternating arrangement of the baffle plates 12, the filtered zinc oxide dust is collected in a step-like manner. At the same time, the brake shaft 14 drives the rotation of the push rods 17 to push the dust on the baffle plates 12 to the bottom of the collection tank 3 for unified collection. The alternating action of the baffle plates 12 can also prevent the dust from splashing back and scattering under the action of wind, ensuring the stability of dust collection.

[0031] It should be noted that the brake shaft 14 is provided with an agitator 13 facing the bottom of the collection tank 3 along its axial direction. By setting the agitator 13 at the bottom of the collection tank 3, the agitator 13 is driven to rotate in real time when the brake shaft 14 rotates, so as to dynamically dispose of the zinc oxide dust in the collection tank 3, thereby avoiding the accumulation and caking of dust and the subsequent inability to unload the material. Example 3:

[0032] Please see Figure 1-6 This embodiment further explains other embodiments: the air inlet of the air inlet box 2 is connected to an air inlet pipe 4, the other end of the air inlet pipe 4 is connected to a telescopic pipe 5, and the other end of the telescopic pipe 5 is connected to an air intake pipe 6. By utilizing the telescopic pipe 5's telescopic characteristics, the orientation of the air intake of the air intake pipe 6 can be adjusted to adapt to the dust-laden environment on site. Specifically:

[0033] The telescopic tube 5 includes a telescopic flexible hose 51 located between the air inlet pipe 4 and the air intake pipe 6. The telescopic flexible hose 51 is provided with a long screw 52 along its circumference, which is bolted to the air inlet pipe 4 and the air intake pipe 6. The screw support of the long screw 52 serves two purposes: firstly, it provides arm support and limits and fixes the combination of the air inlet pipe 4, the telescopic tube 5, and the air intake pipe 6; secondly, it serves as a telescopic adjustment function. By adjusting the position of the bolt on the screw, the telescopic length of the telescopic flexible hose 51 can be adjusted.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
