Description

Technical Field

[0001] This utility model relates to the field of industrial dust removal technology, and in particular to an environmentally friendly dry grinding dust removal chamber. Background Technology

[0002] Traditional dust removal equipment in dust collection rooms suffers from outdated technology, making it difficult to meet the latest environmental emission standards in terms of filtration accuracy and pollutant interception capabilities. Furthermore, achieving the same dust removal effect often requires a significant amount of factory space. Given the rising cost of industrial land and increasingly compact production workshop layouts, this large footprint severely limits its installation and application within limited production spaces, encroaching on valuable production areas and indirectly increasing the company's production and operating costs.

[0003] Traditional dust removal equipment is limited by the arrangement and structural design of the filter material, resulting in a relatively limited filtration area. This leads to a higher filtration velocity, reduced dust deposition efficiency on the filter material surface, and consequently, poor overall dust removal performance.

[0004] In view of this, the present invention is proposed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly dry grinding dust removal room to solve the technical problems of low filtration accuracy and insufficient pollutant interception capacity of existing grinding dust removal rooms.

[0006] The technical solution of this utility model is: an environmentally friendly dry grinding dust removal chamber, comprising: A sanding room, which is equipped with a sanding workbench; The dust collector structure is located outside the grinding chamber. The dust collector structure includes a dust collection box with a dust discharge hopper at the bottom. Multiple filter chambers are arranged along the length of the dust collection box, and each filter chamber is equipped with a filter assembly, which includes a filter cartridge. The lower end of the filter assembly is connected to the dust discharge hopper. A dust suction pipe is located above the grinding workbench. One end of the dust suction pipe, away from the grinding workbench, passes through the grinding chamber and is connected to multiple filter assemblies. An exhaust assembly is located above the dust collection box. One end of the exhaust assembly is connected to the filter chamber, and the other end extends into the grinding chamber.

[0007] Furthermore, a partition is horizontally arranged inside the filter chamber to form a lower dust removal chamber and an upper clean air chamber. The filter assembly is arranged in the lower dust removal chamber, and the upper end of the filter assembly is connected to the partition.

[0008] Furthermore, the filter assembly includes a sealed cylinder vertically disposed in the lower dust removal chamber, the upper end of which is connected to a partition. The filter cartridge is installed inside a sealed cylinder; A dust removal valve is installed at the lower end of the sealing cylinder.

[0009] Furthermore, a sliding pulse valve is installed above the filter cartridge, with the air inlet end of the pulse valve extending out of the upper clean air chamber, and the air inlets of multiple pulse valves are connected through the same compressed air pipe. The outlet of the pulse valve is connected to a venturi tube, the lower end of which extends into the filter cartridge. The diameter of the venturi tube decreases from top to bottom. An electric actuator is installed in the upper air purification chamber, and the output end of the electric actuator is fixedly connected to the upper end of the pulse valve.

[0010] Furthermore, the filter cartridge has a corrugated and pleated structure to increase the filtration area.

[0011] Furthermore, the exhaust assembly includes an exhaust pipe disposed above the dust collection box; Each upper clean air chamber is connected to the exhaust pipe via a connecting pipe; One end of the exhaust pipe is blocked, and the other end is connected to a fan. The air outlet of the fan extends into the grinding chamber.

[0012] Furthermore, a connecting pipe is installed through one side of the ash discharge hopper; One end of the connecting pipe is connected to the dust suction pipe, and the other end of the connecting pipe extends into the dust discharge hopper and is connected to the sealing cylinder.

[0013] Furthermore, a receiving cylinder is installed below the ash discharge hopper.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects: 1. Multiple filter components are used to filter the dust-laden gas in the grinding chamber, increasing the filtration area, improving filtration accuracy and efficiency. The filter cartridges reduce the filtration velocity and increase the deposition efficiency of dust on the surface of the cartridges, thereby improving the dust removal effect. The dust-removed gas is then discharged back into the grinding chamber through the exhaust components to refresh the air and improve the air quality inside the grinding chamber.

[0015] 2. Through the pulse valve and venturi tube, compressed air can be rapidly injected into the filter cartridge in a short time, causing the filter cartridge to expand and deform and vibrate. Under the scouring of the airflow, the dust attached to the outer surface of the filter cartridge is peeled off.

[0016] 3. The filter cartridge has a corrugated and pleated structure, which increases the filtration area and reduces the filtration velocity compared with dust collectors of the same volume, thereby improving filtration efficiency.

[0017] 4. By installing control valves on the connecting pipes and connecting multiple connecting pipes to the dust suction pipe, when cleaning the filter cartridges, the corresponding control valves can be closed for the filter cartridges that need to be cleaned, so that the dust-laden gas passage of the filter cartridge is closed, so as to avoid affecting the cleaning of the filter cartridges and also not interfere with the filtration of other filter cartridges.

Detailed Implementation

[0021] The specific embodiments of this utility model will be described in further detail with reference to the accompanying drawings.

[0022] See Figures 1 to 4As shown in the embodiment of this application, an environmentally friendly dry grinding dust removal room is provided, including: a grinding chamber 1 and a dust collector structure 3. The grinding chamber 1 has a grinding workbench 2. The dust collector structure 3 is located outside the grinding chamber 1 and includes a dust collection box 301. The bottom of the dust collection box 301 has a dust discharge hopper 302. The dust discharge hopper 302 is funnel-shaped, which is conducive to the centralized treatment of dust. Multiple filter chambers are arranged along the length of the dust collection box 301, and each filter chamber is equipped with a filter. The filter assembly includes a filter cartridge 308, the lower end of which is connected to the dust discharge hopper 302. A dust suction pipe 306 is located above the grinding workbench 2. The end of the dust suction pipe 306 near the grinding workbench 2 has a dust suction funnel to increase dust suction efficiency. The end of the dust suction pipe 306 away from the grinding workbench 2 passes through the grinding chamber 1 and is connected to multiple filter assemblies. An exhaust assembly is located above the dust collection box 301. One end of the exhaust assembly is connected to the filter chamber, and the other end extends into the grinding chamber 1.

[0023] In the above scheme, the dust collector structure 3 is set outside the grinding chamber 1. It filters the dust-laden gas in the grinding chamber 1 through multiple filter components, which increases the filtration area of ​​the dust-laden gas, improves the filtration accuracy and filtration efficiency, and reduces the filtration velocity through the filter cartridge 308, thereby increasing the deposition efficiency of dust on the surface of the filter cartridge 308 and thus improving the dust removal effect. The dust-removed gas is discharged back into the grinding chamber 1 through the exhaust component to exchange the air in the grinding chamber 1 and improve the air quality in the grinding chamber 1.

[0024] See some possible implementations. Figure 4 As shown, a partition 310 is horizontally arranged inside the filter chamber to form a lower dust removal chamber and an upper clean air chamber. The filter assembly is arranged in the lower dust removal chamber, and the upper end of the filter assembly is connected to the partition 310. The partition 310 divides the filter chamber into a lower dust removal chamber and an upper clean air chamber to separate the filtered gas from the dust-laden gas, prevent the dust-laden gas from mixing with the filtered gas, and facilitate the discharge of the filtered gas.

[0025] See some possible implementations. Figure 4 As shown, the filter assembly includes a sealing cylinder 307 vertically arranged in the lower dust removal chamber. The upper end of the sealing cylinder 307 is connected to the partition plate 310. The filter cylinder 308 is arranged inside the sealing cylinder 307. The upper end of the filter cylinder 308 is sealed with the inner wall of the sealing cylinder 307, so that the filtered gas enters the upper clean air chamber from the upper end of the filter cylinder 308. A dust removal valve is provided at the lower end of the sealing cylinder 307.

[0026] In the above scheme, the sealing cylinder 307 and the filter cylinder 308 are designed so that after the dust-laden gas enters the sealing cylinder 307, the dust is deposited on the outer surface of the filter cylinder 308. The filtered gas enters the upper clean air chamber through the upper end of the filter cylinder 308. The dust removal valve at the lower end of the sealing cylinder 307 is used to discharge the dust inside the sealing cylinder 307.

[0027] See some possible implementations. Figure 4 As shown, a sliding pulse valve is installed above the filter cartridge 308. The air inlet end of the pulse valve extends out of the upper clean air chamber. The air inlets of multiple pulse valves are connected through the same compressed air pipe 305. The air outlet end of the pulse valve is connected to a venturi tube 309. The lower end of the venturi tube 309 extends into the filter cartridge 308. The diameter of the venturi tube 309 decreases from top to bottom. An electric actuator is installed in the upper clean air chamber. The output end of the electric actuator is fixedly connected to the upper end of the pulse valve. During the dust cleaning process of the filter cartridge 308, the sealing cylinder 307 plays the role of collecting air and increasing the wind speed, thereby improving the dust cleaning effect.

[0028] In the above scheme, when cleaning the dust deposited on the surface of the filter cartridge 308, the electric actuator is activated, causing the output end of the electric actuator to drive the pulse valve and the venturi tube 309 to press down synchronously. This causes the venturi tube 309 to block the air outlet of the filter cartridge 308, open the dust removal valve, and activate the pulse valve, allowing compressed air to rush into the filter cartridge 308 in a short time. This causes the filter cartridge 308 to expand and deform, generating vibration. Under the scouring of the airflow, the dust adhering to the outer surface of the filter cartridge 308 is peeled off, thereby achieving the effect of cleaning the dust.

[0029] See some possible implementations. Figure 4 As shown, the filter cartridge 308 has a corrugated and pleated structure to increase the filtration area. Compared with a dust collector of the same volume, the filtration area is increased and the filtration velocity is reduced, thereby improving the filtration efficiency.

[0030] See some possible implementations. Figure 2 and Figure 3 As shown, the exhaust assembly includes an exhaust pipe 304 located above the dust collection box 301. Each upper clean air chamber is connected to the exhaust pipe 304 via a connecting pipe 311. One end of the exhaust pipe 304 is blocked, and the other end is connected to a fan 4. The air outlet of the fan 4 extends into the grinding chamber 1.

[0031] In the above scheme, the filtered gas enters the exhaust pipe 304 through the connecting pipe 311, and under the action of the fan 4, the filtered gas is extracted and discharged into the grinding chamber 1.

[0032] See some possible implementations. Figure 2 and Figure 3As shown, a connecting pipe 312 is installed through one side of the ash discharge hopper 302. A control valve is installed on the connecting pipe 312. One end of the connecting pipe 312 is connected to the dust suction pipe 306, and the other end of the connecting pipe 312 extends into the ash discharge hopper 302 and is connected to the sealing cylinder 307.

[0033] In the above scheme, the dust-laden gas is drawn out from the grinding chamber 1 through the dust suction pipe 306 and sent into the sealing cylinder 307 through the connecting pipe 312. When cleaning the filter cylinder 308, the corresponding control valve can be closed for the filter cylinder 308 that needs to be cleaned, so that the dust-laden gas passage of the filter cylinder 308 is closed, so as to avoid affecting the cleaning of the filter cylinder 308 and at the same time, it will not interfere with the filtration of other filter cylinders 308.

[0034] See some possible implementations. Figures 2 to 4 As shown, a receiving cylinder 303 is provided below the ash discharge hopper 302 for collecting the filtered dust.

[0035] This specific embodiment is merely an explanation of the utility model and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection of this utility model.
