Description

Technical Field

[0001] This utility model relates to the field of workshop dust removal technology, and more specifically, to a three-stage settling dust removal device. Background Technology

[0002] Some workshops generate a lot of dust during processing, and if this dust is not removed in time, it can seriously affect the health of workers. To solve this problem, dust removal equipment is installed when constructing workshops.

[0003] Existing dust removal equipment used in workshops typically employs the following method: the dust collector first uses an exhaust fan to draw out the dust from the workshop, and then filters the dust using filter cartridges. However, this method has the following drawbacks: the technology only provides simple filtration, dust easily clogs the filter cartridges, requiring weekly manual cleaning, resulting in high maintenance costs; frequent filter cartridge replacements also lead to high spare parts costs; and frequent dust clogging results in poor filtration and ineffective dust removal, failing to meet production requirements.

[0004] Therefore, a three-stage sedimentation dust removal device is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a three-stage sedimentation dust removal device.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A three-stage settling dust removal device includes a coarse particle settling chamber, a medium particle settling chamber, and a fine particle settling chamber connected sequentially by pipes. The coarse particle settling chamber is connected to an air inlet pipe, and the fine particle settling chamber is connected to a filter dust collector. Negative pressure fans are installed in each of the three settling chambers. A dust collection bin is detachably connected to the fine particle settling chamber via a discharge pipe. A valve is installed on the discharge pipe to prevent dust in the dust collection bin from flowing back into the fine particle settling chamber.

[0008] Furthermore, in this utility model, the interior of the discharge pipe is divided into a discharge chamber and an equipment chamber by a partition. Fine particles in the fine particle settling chamber can fall into the dust recovery bin through the discharge chamber. The valve is used to seal the discharge chamber.

[0009] Furthermore, in this utility model, the valve includes several rotating shafts that are rotatably connected to the partition plate. Both ends of any of the rotating shafts extend into the discharge chamber and the equipment chamber, respectively. The rotating shafts are evenly spaced and parallel to each other. Each rotating shaft is provided with a block with the same cross-sectional area. Each block is located within the discharge chamber, and the cross-section of each block is an equilateral triangle. The center of gravity of each block is located on the central axis of the corresponding rotating shaft, and the distance between the central axes of two adjacent rotating shafts is equal to the side length of the block with the equilateral triangle cross-section. One end of each rotating shaft located within the equipment chamber is connected to an intermittent drive mechanism.

[0010] Furthermore, in this utility model, any of the aforementioned rotating shafts is provided with a driven bevel gear at the end located within the aforementioned equipment cavity, a drive shaft is rotatably provided within the aforementioned equipment cavity, and a plurality of driving bevel gears are spaced apart on the aforementioned drive shaft, with the plurality of driving bevel gears meshing one-to-one with the plurality of driven bevel gears; the aforementioned drive shaft is connected to a motor that operates intermittently and is self-locking.

[0011] Furthermore, in this invention, a dust collection bin is provided at the bottom of both the coarse particle settling chamber and the medium particle settling chamber.

[0012] The beneficial effects of this utility model are:

[0013] 1. Excellent dust removal effect: After the workshop dust is processed by this three-stage settling dust removal equipment, it is basically extracted to the outdoor dust collection bin, which can greatly improve the workshop working environment.

[0014] 2. Low maintenance cost: Because the dust is separated in multiple stages, fine dust can be filtered quickly, the filter element of the filter cartridge dust collector is not easy to clog, the cost of purchasing spare parts is reduced and the labor maintenance cost is reduced.

[0015] 3. Dust can be recycled. Workshop dust is separated layer by layer through this three-stage settling dust removal equipment; the dust recovered from the coarse particle settling chamber and the medium particle settling chamber can be sold to generate revenue outside the factory, while the fine dust recovered from the fine particle settling chamber can be recycled and reused.

[0016] 4. The valve installed on the discharge pipe at the bottom of the fine particle settling chamber can prevent the dust in the dust recovery bin below the fine particle settling chamber from flowing back into the fine particle settling chamber during the operation of this three-stage settling dust removal equipment, so as not to affect the service life of the filter dust collector.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A three-stage settling dust removal device includes a coarse particle settling chamber 101, a medium particle settling chamber 102, and a fine particle settling chamber 103 connected sequentially by pipes. The coarse particle settling chamber 101 is connected to an air inlet pipe 104, the other end of which is connected to the interior of the workshop. The fine particle settling chamber 103 is connected to a filter dust collector 105. Negative pressure fans (not shown in the figure) are installed in each of the three chambers. Dust collection bins 107 are installed below each of the three chambers, allowing particles to fall sequentially into their respective dust collection bins 107.

[0025] During processing in the workshop, the negative pressure fan in the coarse particle settling chamber 101 first draws dust-laden air into the chamber through the air inlet duct 104. The denser, coarser dust particles settle naturally into the dust collection bin 107 below under their own gravity. The less dense dust particles are drawn into the medium particle settling chamber 102 by the negative pressure fan, and then settle naturally into the dust collection bin 107 below. The least dense dust particles are drawn into the fine particle settling chamber 103 by the negative pressure fan, and these fine particles in the dust-laden air ultimately settle naturally into the dust collection bin 107 below. The air in the fine particle settling chamber 103 is then filtered again by the cartridge dust collector 105 before being discharged. In this way, the workshop dust is separated layer by layer by the dust removal equipment, and finally all of it falls into the dust collection bin 107.

[0026] However, there is a problem in the above dust removal process: as the dust-laden air flows from the fine particle settling chamber 103 to the filter cartridge dust collector 105, a negative pressure is easily generated in the upper part of the fine particle settling chamber 103. Since the particles in the dust collection bin 107 below the fine particle settling chamber 103 are relatively fine and light, the fine dust particles in this dust collection bin 107 are easily flowed back upward into the fine particle settling chamber 103 under the action of negative pressure. This affects the collection of fine dust particles on the one hand, and on the other hand, if this part of the upward-flowing fine dust particles enters the filter cartridge dust collector 105, it will affect the normal use of the filter cartridge dust collector 105 and its service life over a long period of time.

[0027] Therefore, in order to solve the above problems, the fine particle settling chamber 103 is connected to the dust collection bin 107 located below it through the discharge pipe 106, and a valve is installed on the discharge pipe 106 to prevent the fine particle dust in the dust collection bin 107 below the fine particle settling chamber 103 from flowing back upward into the fine particle settling chamber 103.

[0028] Reference Figure 3 and Figure 4In this embodiment, the interior of the discharge pipe 106 is divided into a discharge chamber 202 and an equipment chamber 203 by a partition 201. Fine particles in the fine particle settling chamber 103 can fall into the dust collection bin 107 through the discharge chamber 202. A valve is used to seal the discharge chamber 202. Specifically, the valve includes three rotating shafts 301, each rotatably connected to the partition 201. Both ends of any rotating shaft 301 extend into the discharge chamber 202 and the equipment chamber 203, respectively. The three rotating shafts 301 are evenly spaced and parallel to each other. A blocking block 302 with the same cross-sectional area is installed on each rotating shaft 301. Each blocking block 302 is located within the discharge chamber 202, has an equilateral triangular cross-section, and its center of gravity is located on the central axis of the corresponding rotating shaft 301. The distance between the central axes of two adjacent rotating shafts 301 is equal to the side length of the block 302 with an equilateral triangular cross-section; a driven bevel gear 303 is installed at one end of any rotating shaft 301 located in the equipment chamber 203; a drive shaft 304 is rotatably installed in the equipment chamber 203; three driving bevel gears 305 are installed at intervals on the drive shaft 304; the three driving bevel gears 305 mesh with the three driven bevel gears 303 in a one-to-one correspondence; and the drive shaft 304 is connected to an intermittently working and self-locking motor 306.

[0029] from Figure 4 From the perspective of normal operation, when the three-stage dust collector is working normally, fine dust particles will gradually accumulate on the upper surfaces of the three blocking blocks 302. During normal operation of the three-stage dust collector, the motor 306 also works, intermittently driving the drive shaft 304, causing the drive shaft 304 to rotate 120° every certain period of time. Under the drive of the bevel gear mechanism, the three blocking blocks 302 rotate 120° clockwise / counterclockwise synchronously. In this way, the surface of the blocking block 302 with accumulated dust will be located below the blocking block 302, and the dust accumulated on it will fall into the dust collection bin 107 below. In this way, after each 120° rotation of the drive shaft 304, the corresponding surfaces of the blocking blocks 302 can combine to block the discharge chamber 202, preventing the dust in the dust collection bin 107 below from flowing back upward into the fine particle settling chamber 103 under the action of negative pressure.

[0030] In other embodiments of this example, the number of block 302 can be increased or decreased as needed.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
