Description

Technical Field

[0001] This utility model relates to the field of dust treatment technology for powder production, and in particular to a dust treatment device for powder production. Background Technology

[0002] Dust control devices for powder production are primarily used to collect and purify dust generated during the production process, ensuring a safe working environment and compliance with environmental protection requirements. Core equipment includes cyclone separators, bag filters, or electrostatic precipitators, which efficiently capture fine particles through physical filtration, centrifugal separation, or electrostatic adsorption, and maintain continuous filtration efficiency in conjunction with pulse-jet or vibration cleaning systems. The devices typically integrate fans, piping systems, and automated control systems to monitor dust concentration in real time and adjust airflow. They are also equipped with closed-loop conveying and centralized emission treatment units to ensure emissions meet standards (such as PM10 and PM2.5 limits), balancing production efficiency and environmental compliance.

[0003] In the prior art, Chinese utility model patent CN216856352U discloses a dust treatment device for polyester powder coating production, including a support frame, a mixing box fixed to the inner bottom surface of the support frame, a motor installed on the side of the mixing box, the shaft end of the motor extending into the mixing box and connected to a stirring device, a removable box cover on the top surface of the mixing box, a liquid tank held in place at the upper part of the support frame, a removable filter assembly disposed between the inner walls of the liquid tank, and a connecting pipe disposed on the box cover and communicating with the inside of the mixing box on the bottom surface of the liquid tank. This allows for convenient filtration of inorganic particles in the polyester powder liquid, facilitating the mixing and discharge of the filtered solution for later use. The entire filtration method is simple, and the filter plate and the whole assembly can be easily disassembled, making it convenient for maintenance and cleaning, thus better meeting the needs of use.

[0004] Problems compared with existing technologies: Some existing dust treatment devices for powder production cannot remove dust particles filtered out by the filter screen in a timely manner during the dust treatment process. Dust particles tend to accumulate on the filter screen, and dust tends to stick to the inner wall of the treatment equipment, affecting the dust treatment efficiency.

[0005] Therefore, there is an urgent need for a dust treatment device for powder production. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dust treatment device for powder production.

[0007] The present invention solves its technical problem through the following technical solution: It includes a dust collection box and a processing mechanism disposed inside the dust collection box for processing dust generated during powder production. The processing mechanism includes a rotating shaft rotatably connected to the middle position of the processing box. A bushing is fixedly installed on the outer side of the rotating shaft, and sieve plates are fixedly installed on both sides of the bushing. Scrapers are fixedly installed at both ends of the sieve plates. A dust collection box is provided at the bottom of the processing box. Multiple ventilation holes are evenly arranged on one side of the processing box. The invention also includes a driving mechanism disposed outside the processing box for driving the rotating shaft to rotate. The driving mechanism includes a support arm fixed to the outer wall of the processing box by bolts. A forward and reverse motor is fixedly installed on one side of the support arm. A worm gear is fixedly installed at the rotating end of the forward and reverse motor. A worm wheel is fixedly installed at one end of the rotating shaft, and the worm wheel is connected to the worm gear via a transmission.

[0008] As a further embodiment of this utility model: the dust collection box is provided with a feeding mechanism for driving the dust in the powder production process to feed. The feeding mechanism includes a servo motor, which is fixed to one end of the dust collection box by bolts. A spiral blade is fixedly installed on the rotating end of the servo motor. A damping hinge is fixedly installed on one end of the dust collection box, and a baffle is fixedly installed on one end of the damping hinge.

[0009] As a further embodiment of this utility model: a dust collection mechanism is provided on one side of the processing box for attracting dust from the powder production process. The dust collection mechanism includes a dust collection pipe, which is welded to one end of the processing box. A bellows is fixedly installed at one end of the dust collection pipe. A drive motor is fixedly installed inside the bellows. Multiple fan blades are fixedly installed at the rotating end of the drive motor. A protective shell is fixedly installed on the outside of the drive motor.

[0010] As a further improvement of this utility model, a transparent window is fixedly installed on one side of the processing box.

[0011] As a further improvement of this utility model, a tapered end is fixedly installed at one end of the protective shell.

[0012] As a further improvement of this utility model: a diffuser cover is fixedly installed on the outside of the vent hole, and a grid plate is fixedly installed on one end of the air box.

[0013] As a further improvement of this utility model: a mounting frame is fixedly installed below the processing box, and a base plate is fixedly installed below the mounting frame.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. The worm gear is driven to rotate by a forward and reverse motor. The worm gear drives the rotating shaft to rotate through the worm wheel. The self-locking property of the worm wheel and worm gear prevents the screen plate from rotating in reverse. This causes the screen plate to rotate back and forth, shaking off the dust particles screened out by the screen plate and preventing the dust particles from accumulating on the screen plate and avoiding clogging of the filter screen.

[0016] 2. The forward and reverse motor can drive the screen plate to rotate through the rotating shaft. The screen plate drives the scraper to scrape along the inner wall of the processing box to clean the dust adhering to the inner wall of the processing box. At the same time, the screen plate can push the collected dust particles into the dust collection box for collection, ensuring the dust treatment efficiency of the dust treatment device for powder production.

[0017] 3. The servo motor drives the spiral blades to rotate, automatically feeding the dust particles collected by the dust treatment device for powder production. The damping hinge automatically closes or opens the dust collection box for feeding, ensuring the automation level of the dust treatment device for powder production. Attached Figure Description

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figure 1-4As shown, a dust handling device for powder production includes a dust collection box and a processing mechanism disposed inside the dust collection box for handling dust generated during the powder production process. A transparent window 110 is bolted to one side of the processing box 100, allowing observation of the dust handling process during powder production. The processing mechanism includes a rotating shaft 101 rotatably connected to the center of the processing box 100. A bushing 102 is bolted to the outer side of the rotating shaft 101. The bushing 102 has a sieve plate 103 bolted to both sides, allowing the bushing 102 to rotate the sieve plate 103. Scrapers 104 are bolted to both ends of the sieve plate 103, scraping along the inner wall of the treatment box 100 while preventing leakage from the gap between the scraper 104 and the inner wall of the treatment box 100. A dust collection box 105 is slidably connected to the bottom of the treatment box 100. Multiple ventilation holes 106 are evenly cut on one side of the treatment box 100, filtering out dust. To depressurize the gas, a diffuser 300 is bolted to the outside of the vent 106, increasing the pressure release area. The system also includes a drive mechanism located outside the processing chamber 100 to drive the rotating shaft 101 to rotate. The drive mechanism includes a support arm 201 bolted to the outer wall of the processing chamber 100. A reversible motor 202 is bolted to one side of the support arm 201, and a worm gear is bolted to the rotating end of the reversible motor 202. The worm gear 203 is driven to rotate by the forward and reverse motor 202. One end of the rotating shaft 101 is fixed with a worm wheel 204 by bolts. The worm wheel 204 is connected to the worm gear 203 for transmission. The worm gear 203 drives the worm wheel 204 to rotate, which in turn drives the screen plate 103 to rotate through the rotating shaft 101. The processing box 100 is fixed to the bottom by bolts with a mounting bracket 500. The processing box 100 is fixed by the mounting bracket 500. The bottom plate 600 is fixed to the bottom of the mounting bracket 500 by bolts.

[0034] In this embodiment, the worm gear 203 is driven to rotate by the reversible motor 202. The worm gear 203 drives the rotating shaft 101 to rotate via the worm wheel 204. The self-locking property of the worm wheel 204 and the worm gear 203 prevents the screen plate 103 from reversing, thereby driving the screen plate 103 to rotate back and forth, shaking off the dust particles screened out by the screen plate 103, preventing the dust particles from accumulating on the screen plate 103 and avoiding the filter screen from clogging. Furthermore, the reversible motor 202 can drive the screen plate 103 to rotate via the rotating shaft 101. The screen plate 103 drives the scraper 104 to scrape along the inner wall of the processing box 100 to clean the dust adhering to the inner wall of the processing box 100. At the same time, the screen plate 103 can push the collected dust particles into the dust collection box 105 for collection, ensuring the dust treatment efficiency of the dust treatment device for powder production.

[0035] Example 2

[0036] like Figure 1-5 As shown, a dust handling device for powder production includes a dust collection box 105 with an internal feeding mechanism for discharging dust generated during powder production. The feeding mechanism includes a servo motor 301, which is bolted to one end of the dust collection box 105. A spiral blade 302 is bolted to the rotating end of the servo motor 301, causing the spiral blade 302 to rotate. A damping hinge 303 is bolted to one end of the dust collection box 105, which uses its elasticity to close a baffle 304. Dust particles requiring discharge push the baffle 304 to open. A suction mechanism is located on one side of the handling box 100 to attract dust generated during powder production. The dust collection mechanism includes a dust collection pipe 401, which is welded to one end of the processing box 100. One end of the dust collection pipe 401 is bolted to a bellows 402, and one end of the bellows 402 is bolted to a grille 400 to prevent other objects from entering the bellows 402. Inside the bellows 402, a drive motor 403 is bolted to the inside. The rotating end of the drive motor 403 is bolted to multiple fan blades 404, which drive the multiple fan blades 404 to rotate and generate negative pressure. A protective shell 405 is bolted to the outside of the drive motor 403 to protect it. One end of the protective shell 405 is bolted to a tapered end 200, which reduces the obstruction of dust particles by the protective shell 405.

[0037] In this embodiment, the servo motor 301 drives the spiral blades 302 to rotate, automatically feeding the dust particles collected by the dust treatment device for powder production. The damping hinge 303 automatically closes or opens the dust collection box 105 to feed the dust, ensuring the automation level of the dust treatment device for powder production. The drive motor 403 drives multiple fan blades 404 to rotate, generating negative pressure to attract the dust from powder production, ensuring the dust processing speed.
