Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and more specifically to a dust removal equipment for production workshops. Background Technology

[0002] Most production workshops use exhaust fans and corresponding filters to remove most of the dust in the air, thereby improving the air quality in the workshop.

[0003] According to patent publication number CN212419032U, published on January 29, 2021, a dust removal device for an injection molding workshop is disclosed, including an exhaust fan for installation on a wall and a dust filter for blocking the exhaust fan. An exhaust pipe is provided on one side of the exhaust fan, and an installation port for the dust filter to enter the exhaust pipe is opened on the exhaust pipe. The installation port communicates with the hollow part of the exhaust pipe. The dust filter is slidably connected to the exhaust pipe and to the installation port. A first slot is opened on the inner wall of the exhaust pipe, and a first elastic locking component is provided on the dust filter for locking with the first slot to restrict the sliding of the dust filter.

[0004] In the prior art, including the aforementioned patent, although effective filtration can be achieved through exhaust fans and dust filters, most of the dust will be directly blocked by the dust filters, which will result in a heavy burden on the dust filters and require frequent replacement and maintenance over a period of time. Utility Model Content

[0005] The purpose of this utility model is to provide a dust removal device for production workshops, which achieves a certain dust filtration effect by settling and blocking dust, and by combining it with components such as dust filter screens to achieve the dust removal effect, thereby reducing the burden on the dust filter screens and reducing the frequency of dust filter screen replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for a production workshop, comprising a dust removal cylinder and a support plate fixedly installed therein. The outer wall of the dust removal cylinder is provided with air inlets arranged in a circular array. An air guide pipe is fixedly installed on the support plate. A filter cartridge is provided at the top of the air guide pipe. An air outlet pipe communicating with the air guide pipe is fixedly installed at the bottom of the support plate, and an exhaust fan is fixedly installed inside the air outlet pipe.

[0007] Preferably, the outer wall of the air duct is fixedly installed with dust-proof spiral blades.

[0008] Preferably, the top of the dust collector is provided with a slot, and a sealing cover is snapped onto the slot.

[0009] Preferably, an installation plate is fixedly installed on the outer wall of the air outlet duct, and ash collection boxes are symmetrically arranged on the top of the installation plate, and ash drop grooves are opened on the top of the tray.

[0010] Preferably, the inner wall of the air duct is fixedly equipped with drive spiral blades arranged in a circular array.

[0011] Preferably, the bottom of the mounting plate is fixedly equipped with multiple casters.

[0012] Preferably, bearing components are provided at both ends of the air duct.

[0013] Preferably, the air duct is made of aluminum alloy.

[0014] Preferably, the ash collection box is an aluminum alloy box.

[0015] In the above technical solution, the dust removal equipment for production workshops provided by this utility model has the following beneficial effects: It achieves all-round air suction and dust removal through the circular array of air inlets on the outer wall of the dust collector. The space above the support plate and around the filter cartridge forms a pre-treatment settling zone. Dust-laden air must first pass through the pre-treatment zone before reaching the filter cartridge. The exhaust fan provides suction. During use, dust-laden air enters the large pre-treatment space inside the dust collector evenly from the air inlet. In this space, the airflow velocity naturally decreases, and some heavier and larger dust particles naturally settle under gravity. Subsequently, the pre-purified air is drawn into the air duct and passes through the filter cartridge for fine filtration, thereby reducing the burden on the filter cartridge and decreasing the frequency of dust filter replacement.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, a dust removal device for a production workshop includes a dust collection cylinder 1 and a support plate 12 fixedly installed inside it. The outer wall of the dust collection cylinder 1 has air inlets 13 arranged in a circular array. A guide pipe 3 is fixedly installed on the support plate 12. A filter cartridge 4 is installed on the top of the guide pipe 3. An air outlet pipe 15 connected to the guide pipe 3 is fixedly installed at the bottom of the support plate 12, and an exhaust fan 5 is fixedly installed inside the air outlet pipe 15. The circular array of air inlets 13 on the outer wall of the dust collection cylinder 1 enables all-round suction and dust removal. The space above the support plate 12 and around the filter cartridge 4 forms a pretreatment settling zone. Dust-laden air must pass through the pretreatment zone before reaching the filter cartridge 4. The exhaust fan 5 provides suction. In use, dust-laden air enters the large pretreatment space inside the dust collection cylinder 1 evenly from the air inlets 13. In this space, the airflow velocity naturally decreases, and some heavier and larger dust particles settle naturally under gravity. Subsequently, the preliminarily purified air is drawn into the air duct 3 and passes through the filter cartridge 4 for fine filtration, which can reduce the burden on the filter cartridge 4 and reduce the frequency of dust filter replacement.

[0021] As a further technical solution provided by this utility model, a dust-proof spiral blade 31 is fixedly installed on the outer wall of the air duct 3.

[0022] Specifically, through multiple dust-proof spiral blades 31, dust is further blocked and isolated from depositing when it passes through the dust-proof spiral blades 31, and some dust can be adsorbed on the dust-proof spiral blades 31, thereby reducing the burden of dust on the filter cartridge 4.

[0023] Furthermore, a slot 11 is provided at the top of the dust collector 1, and a sealing cover 22 is snapped onto the slot 11.

[0024] Specifically, the slot 11 facilitates the removal and placement of the filter cartridge 4 for cleaning and replacement, while the sealing cover 22 can be used to seal it, preventing air from being drawn in along the slot 11 and affecting the dust filtration effect.

[0025] Furthermore, an installation plate 16 is fixedly installed on the outer wall of the air outlet duct 15, and ash collection boxes 2 are symmetrically arranged on the top of the installation plate 16, and ash drop grooves 14 are opened on the top of the support plate 12.

[0026] Specifically, the dust drop channel 14 allows the dust continuing to fall from the tray 12 to the dust collection boxes 2 symmetrically arranged on the top of the mounting plate 16. The two dust collection boxes 2 can surround the air outlet duct 15 and be interlocked and fixed to each other, thus facilitating quick disassembly and cleaning.

[0027] Furthermore, the inner wall of the air duct 3 is fixedly equipped with drive spiral blades 32 arranged in a circular array.

[0028] Specifically, the air duct 3 is rotatably mounted on the top of the tray 12. When the flowing air passes through the dust-proof spiral blades 31 and then through the filter cartridge 4 and enters the air duct 3, the airflow then flows through the drive spiral blades 32 again. Under the double-layer agitation of the airflow on the dust-proof spiral blades 31 and the drive spiral blades 32, the air duct 3 is driven to rotate. When the air duct 3 rotates, the dust-proof spiral blades 31 agitate the dust on the top of the tray 12 and send it into the dust collection trough 14, thereby achieving a certain degree of cleaning. The rotating air duct 3 can also accelerate the dust on the dust-proof spiral blades 31 to fall to the top of the tray 12 for collection.

[0029] Furthermore, multiple casters 21 are fixedly installed on the bottom of the mounting plate 16.

[0030] Specifically, multiple casters 21 are used to facilitate the transfer and use of the dust collection cylinder 1.

[0031] Furthermore, bearing components 6 are respectively installed at both ends of the air duct 3.

[0032] Specifically, the friction between the air duct 3 and the support plate 12 and the filter cartridge 4 is reduced by using the bearing component 6.

[0033] Furthermore, the air duct 3 is made of aluminum alloy.

[0034] Furthermore, the ash receiving box 2 is an aluminum alloy box.

[0035] Working Principle: Dust-laden air first enters the dust collector 1 evenly through the circular array of air inlets 13 on the outer wall of the dust collector 1. Due to the omnidirectional distribution of the air inlets 13, the airflow naturally slows down in the large pre-treatment space inside the dust collector 1, forming a pre-treatment settling zone. Some heavier and larger dust particles settle naturally under gravity. Subsequently, the preliminarily purified air is drawn into the air guide duct 3. The dust-proof spiral blades 31 fixedly installed on the outer wall of the air guide duct 3 further block and isolate dust, with some dust adsorbed on the blade surface, reducing the burden on subsequent filtration. At the same time, the airflow drives the dust-proof spiral blades 31 on the outer wall of the air guide duct 3 and the drive spiral blades 32 on the inner wall, causing the air guide duct 3 to rotate on the support plate 12 supported by the bearing 6. The rotating dust-proof spiral blades 31 sweep the accumulated dust on the top of the support plate 12 into the dust collection groove 14, achieving dynamic self-cleaning. The air then passes through the filter cylinder 4 for fine filtration. The filtered clean air enters the interior of the air guide duct 3 and is discharged by the exhaust fan 5 through the outlet duct 15. Settled dust falls through the dust collection trough 14 into the symmetrically arranged dust collection boxes 2 on the top of the mounting plate 16. The dust collection boxes 2 surround the exhaust duct 15 and are detachable for easy cleaning. The slot 11 at the top of the dust collector 1 is sealed by the sealing cover 22, facilitating the replacement and maintenance of the filter cartridge 4. The casters 21 at the bottom of the equipment support flexible movement. Through the synergy of pre-treatment settling, spiral blade blocking, fine filtration by the filter cartridge 4, and multi-stage dust collection, the overall system significantly reduces the load on the filter cartridge 4, decreases maintenance frequency, and improves dust removal efficiency and automation level.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
