AI Technical Summary
In existing dust removal devices, dust adheres to particles and falls rapidly, causing the negative pressure suction of the fan to be unable to effectively and thoroughly absorb the dust.
An air purification particulate dust removal device was designed, including a support frame, a dust collection box, an air intake pipe and a negative pressure fan. The device uses an inclined slide, a baffle chamber and a bent baffle plate to reduce the falling speed of particles, and the dust is drawn away through the air intake pipe. The separation of particles and dust is achieved by combining a wave-shaped deceleration strip and a uniformly distributed toothed plate.
By reducing the falling velocity of particles and utilizing the difference in specific gravity, dust mixed in with material particles is efficiently removed, achieving the separation and purification of dust-free materials.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust particle removal technology, specifically to an air purification particulate dust removal device. Background Technology
[0002] Material granules (such as activated carbon granules, activated manganese granules, etc.) contain a large amount of ash, which causes serious dust pollution during packaging, endangering workers' health. Dust accumulation can also create various safety hazards.
[0003] Currently, there are also some dust removal devices on the market, such as a fine particle screening bin with Chinese patent publication number CN104438080A. The screening bin consists of a back-blowing fan, a screening plate, a hopper, a primary back-blowing pipe, a secondary back-blowing pipe, a hopper inlet, a hopper outlet, a powder outlet, and a powder collection pipe. The back-blowing fan separates fine particles into the hopper through the primary back-blowing pipe and the secondary back-blowing pipe.
[0004] The dust removal devices mentioned above have the following shortcomings: the particles fall vertically and at a fast speed, and the dust will adhere to the particles and fall rapidly with them, causing the negative pressure suction of the fan to be unable to effectively and thoroughly absorb the dust. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this invention provides an air purification particulate dust removal device that can efficiently remove dust mixed in with material particles.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: an air purification particulate dust removal device, comprising a support frame, a dust collection box mounted on the support frame, and an air suction pipe connected to the dust collection box. A negative pressure fan is mounted on the air suction pipe. The dust collection box contains, in sequence along the material flow direction, a feeding chamber, a separation chamber, and a baffle chamber. The bottom of the feeding chamber and the separation chamber are downwardly inclined slides. A bent baffle plate is mounted on the inner wall of the baffle chamber. The inlet of the feeding chamber is a feeding port, and the outlet of the baffle chamber is a discharging port. The inlet end of the air suction pipe is vertically connected to the separation chamber and vertically corresponds to the baffle chamber.
[0009] Preferably, the feeding chamber and the separation chamber are separated by a base plate, and several through holes are provided at the lateral spacing of the connection between the base plate and the slide.
[0010] Preferably, a uniformly distributed toothed plate is provided at the junction of the slide end and the baffle cavity, and the tooth shape of the uniformly distributed toothed plate is a transversely arrayed triangular tooth.
[0011] Preferably, the slide rail is provided with several wave-shaped deceleration bars, each of which corresponds to a tooth of the evenly distributed toothed plate.
[0012] (III) Beneficial Effects
[0013] This invention provides an air purification particulate dust removal device. It has the following beneficial effects:
[0014] 1. This air purification particulate dust removal device reduces the falling speed of material particles by setting an inclined slide and a baffle chamber. Utilizing the difference in specific gravity between material particles and dust, the dust mixed in with the particles is drawn away by the exhaust during the falling process, resulting in dust-free material particles. The dust that is raised is intercepted by the dust collector, thereby efficiently removing the dust mixed in with the material particles. Attached Figure Description

[0019] This utility model provides an air purification particulate dust removal device, such as... Figure 1-3 As shown, it includes a bracket 2, a dust collection box 1 set on the bracket 2, and an air suction pipe 3. The air suction pipe 3 is connected to the dust collection box 1, and a negative pressure fan is installed on the air suction pipe 3 to suck out the dust.
[0020] like Figure 2 and Figure 3 As shown, inside the dust collector 1, along the material flow direction, are the feeding chamber 14, the separation chamber 15, and the baffle chamber 17. The bottom of the feeding chamber 14 and the separation chamber 15 is a downward-sloping slide 18, and the optimal angle between the horizontal plane of the slide 18 and the horizontal plane is about 20°-45°. The relatively flat inclined slide 18 is more conducive to reducing the falling speed of the particulate material.
[0021] The feeding chamber 14 and the separation chamber 15 are separated by a base plate 13. Several through holes 19 are provided at the lateral spacing of the connection between the base plate 13 and the slide rail 18. The material in the feeding chamber 14 enters the separation chamber 15 through a row of through holes 19. The flow rate of the material entering the separation chamber 15 is limited by setting the size of the through holes 19.
[0022] A uniformly distributed toothed plate 4 is provided at the junction of the end of the slide 18 and the baffle cavity 17. The tooth shape of the uniformly distributed toothed plate 4 is a transverse array of triangular teeth. The material flowing out of the slide 18 will leak out through the gaps between the adjacent teeth of the uniformly distributed toothed plate 4, which can make the material fall evenly into the baffle cavity 17. The uniform distribution of material particles is more conducive to the separation of particles and dust.
[0023] A bent baffle plate 16 is provided on the inner wall of the baffle chamber 17. The tip of the baffle plate 16 is laterally facing the horizontal direction of the feed, so that the material sliding down from the slide 18 is decelerated after landing on the baffle plate 16 and is deflected back into the baffle chamber 17 in the opposite direction. The inlet of the feed chamber 14 is the feeding port 11, through which material is added. The outlet of the baffle chamber 17 is the discharge port 12, through which material is discharged. The inlet end of the suction pipe 3 is vertically connected to the separation chamber 15 and vertically corresponds to the baffle chamber 17.
[0024] To reduce the falling speed of the particles, several wavy deceleration strips 5 are arranged laterally on the slide 18. The deceleration strip inlet formed between every two adjacent deceleration strips 5 corresponds to a through hole 19, and the several deceleration strips 5 correspond one-to-one with the teeth of the evenly distributed toothed plate 4. By setting the wavy deceleration strips 5, the flow rate of the passing material is made slower.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
