Description

Technical Field

[0001] This utility model relates to the technical field of refractory material production equipment, specifically a dust prevention device for conveying refractory brick powder. Background Technology

[0002] In the production of refractory bricks, the conveying of powdered raw materials is a crucial step in the entire process. These powders are typically lightweight and extremely fine, exhibiting significant flowability and suspension characteristics. Due to material drops, shaking, impacts, and airflow, a large number of fine particles are dispersed into the air. This not only causes invisible losses of raw materials, directly affecting the product's proportioning accuracy and final cost, but more seriously, the flying dust permeates the entire workplace, deteriorating the production environment and posing a potential threat to the health of operators, as well as certain safety hazards. Therefore, effectively controlling dust during the powder conveying process is one of the core issues for ensuring production safety, improving product quality, and protecting the environment. Existing open or semi-closed conveying equipment is difficult to effectively suppress dust emission, resulting in a harsh working environment. This not only endangers the health of operators and causes waste of raw materials, but also poses a safety hazard of dust explosion. Furthermore, the amount of cleaning and maintenance required after the emitted dust settles is enormous. Therefore, we propose a new dust control device for conveying refractory brick powder.

Detailed Implementation

[0014] 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.

[0015] This utility model embodiment provides a dust-prevention device for conveying refractory brick powder. Please refer to [link / reference]. Figures 1-4 A dust-prevention device for conveying refractory brick powder includes a conveying device 1, which is used to carry and continuously convey powder. A dust-prevention component 2 is provided on the top of the conveying device 1, and a dust removal component 3 is provided on the outer side wall of the dust-prevention component 2, which is used to actively collect and filter the dust generated during the conveying process.

[0016] The dust prevention component 2 includes a sealing cover 201, which is disposed on the top of the conveying device 1 to form the main physical isolation space. A dust removal channel 202 is fixedly connected to the top of the sealing cover 201. This channel serves as a path for dust collection and airflow guidance. A feed inlet 203 is fixedly connected to the top of the dust removal channel 202.

[0017] Furthermore, the conveying device 1 includes a fixed frame 101, which provides structural support and stability for the entire device. A conveyor belt 102 is provided on the top of the fixed frame 101 as the core moving part for powder conveying. A guardrail 103 is also fixedly connected to the top of the fixed frame 101 to prevent powder from spilling from both sides during the conveying process.

[0018] Furthermore, the bottom of the sealing cover 201 is provided with an opening, and a flexible sealing curtain 205 is provided at the opening. The bottom of the flexible sealing curtain 205 is attached to the top of the conveyor belt 102 to achieve dynamic sealing and effectively prevent dust from escaping from the bottom of the cover.

[0019] Furthermore, the inner wall of the dust removal channel 202 is also fixedly connected to a discharge port 204, which is used to guide the powder to the conveyor belt 102 below. Both the discharge port 204 and the inlet 203 are set in a funnel shape to reduce the impact and splashing during feeding and dropping.

[0020] Furthermore, the dust removal assembly 3 includes a dust removal box 301, which is fixedly connected to the outer wall of the dust removal channel 202 and constitutes the main body of the filtration system. Multiple filter cartridges 302 are provided inside the dust removal box 301 for capturing and filtering dust particles in the dusty air.

[0021] Furthermore, multiple filter cartridges 302 are fixedly connected to the side wall of the dust collection box 301, and the inlets of multiple filter cartridges 302 face the inside of the dust collection channel 202 to efficiently draw in dust-laden air. A fan 303 is installed at the bottom of the dust collection box 301 to provide suction power for the entire dust collection system and maintain the internal negative pressure environment.

[0022] Furthermore, the outer wall of the dust collector 301 is provided with an inspection door 304 to facilitate the maintenance and replacement of the filter cartridge 302, and the outer wall of the dust collection channel 202 is provided with an observation window 4 for real-time monitoring of the internal material conveying and dust conditions.

[0023] It should be noted that the multiple filter cartridges 302 are all bolted to the side wall of the dust collector 301. After the dust removal work is completed, the multiple filter cartridges 302 can be disassembled through the inspection door 304, so that the powder inside can be reused and the economic benefits can be improved.

[0024] It should be noted that the diameter of the discharge port 204 is slightly smaller than that of the inlet port 203. This design can balance the airflow inside the sealing cover 201. When the discharge port 204 and the inlet port 203 are of equal size, the negative pressure may be more concentrated in the section near the dust collection box 301, resulting in insufficient suction at the far end of the sealing cover 201. The appropriate narrowing can adjust the pressure distribution of the entire system, making the suction from the inlet port 203 to the discharge port 204 more uniform, ensuring that the dust in the entire dust collection channel 202 can be effectively captured.

[0025] Working principle: This refractory brick powder conveying dust prevention equipment is based on the combination of closed conveying and negative pressure dust removal. During operation, refractory brick powder is fed into the dust removal channel 202 through the funnel-shaped inlet 203 at the top, and then falls onto the conveyor belt 102 through the funnel-shaped outlet 204 at the bottom of the channel. The conveyor belt 102 is completely covered by a sealing cover 201, and a flexible sealing curtain 205 is installed at the bottom of the cover. The sealing curtain is tightly attached to the surface of the conveyor belt 102, forming a relatively closed conveying space, thereby physically preventing the dust from escaping.

[0026] Meanwhile, after the equipment is started, the fan 303 installed outside the dust collection box 301 starts to work, generating a continuous micro negative pressure inside the sealing cover 201 and the dust collection channel 202. Under this negative pressure, even if dust is raised during the material falling and conveying process, it will be carried by the airflow and sucked into the dust collection box 301. The dust collection box 301 is equipped with multiple filter cartridges 302 with inlets facing inward. When the dust-laden air passes through the filter cartridges 302, the dust is captured and filtered by the surface of the filter cartridges 302, and the clean air passes through the filter cartridges 302 and is discharged by the fan 303. The captured dust accumulates on the outer surface of the filter cartridges 302 and can be cleaned or replaced by periodically opening the maintenance door 304. By combining airtight protection with negative pressure dust collection, the equipment effectively solves the dust problem of refractory brick powder during the conveying process.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
