Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a modular mixing device with automatic backflushing function. Background Technology

[0002] The mixing system is the most important production equipment and process in the front end of abrasive manufacturing. It mainly includes a hopper, mixing device, drive device, screening device, dust collection system, and discharge device. A high-quality mixing device can ensure that different materials are mixed in proportion and uniformly, which is crucial for abrasive manufacturing because the uniformity of raw materials directly affects the performance and quality of the abrasive. The screening system can effectively remove impurities to avoid affecting the quality of the final product. The dust collection system effectively reduces dust pollution, protects the health of workers, and meets environmental protection requirements. In order to further improve the life of the mixing equipment, reduce dust pollution, and improve site utilization, a compact modular mixing device with automatic backflushing function is proposed.

[0003] The existing mixing devices suffer from several drawbacks. The modules are not rationally arranged; the bins and mixers cannot be stacked vertically or laid out in a compact horizontal layout, resulting in wasted space. Furthermore, existing mixing devices typically lack automatic backflushing, preventing the cleaning of dust filtered from the PTFE-coated filter cartridges. This can easily lead to excessive airflow damaging the PTFE-coated filter cartridges and compromises the cleaning effect. Additionally, some materials adhere to the inner walls of the mixer during use. Existing mixing devices cannot scrape off this material from the inner walls of the first and second mixing bins, making it difficult to clean and rendering the mixing devices impractical.

The input end of the first blower passes through the first... A mixing bin extends into the interior of a first mixing bin. The output end of the first blower passes through a dust collection bin and extends into the interior of the dust collection bin.

The output end of the second blower passes through a dust collection bin and extends into the interior of the dust collection bin. Both the first and second mixing bins have discharge holes on their inner walls for discharging materials. Valves are fitted on the surfaces of both the first and second mixing bins. The input end of the valve is electrically connected to the output end of a control button.

[0007] Preferably, both the first mixing box and the second mixing box are provided with scraper frames inside. The surfaces of the scraper frames are fixed to the surfaces of the mixers.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the modular mixing device with automatic backflushing function not only enables the mixing device to clean the dust filtered on the surface of the PTFE coated filter cartridge during use, avoiding damage to the PTFE coated filter cartridge by excessive airflow, but also ensures the cleaning effect on the surface of the PTFE coated filter cartridge.

The fan body reverses the airflow and sends it into the surface of the PTFE-coated filter cartridges inside the dust collection box, forcing the dust and impurities adhering to the surface of the PTFE-coated filter cartridges to fall off, thereby restoring dust collection efficiency. An airflow distribution valve distributes compressed air to each back-blowing nozzle as needed. This ensures that the PTFE-coated filter cartridges in different positions are cleaned evenly. A timer controls the controller to operate according to the actual needs of the equipment, and the controller in turn controls the fan body to perform back-blowing.

[0013] 2. By incorporating a scraping and anti-sticking mechanism, when the mixer rotates inside the first and second mixing bins, it drives the scraper frame and scraper plate to rotate inside the first and second mixing bins. At this time, under the elastic force of the spring inside the scraper frame, the scraper plate moves inside the scraper frame and slides inside the guide groove. The guide groove guides the scraper plate, and the spring ensures that the scraper plate always moves until it contacts the inner wall of the first and second mixing bins. Under the combined action of the scraper plate and the scraper frame, the material adhering to the inner wall of the first and second mixing bins can be scraped off. This achieves the function of scraping off the material adhering to the inner wall of the first and second mixing bins, thus preventing the material from sticking to the inner wall of the first and second mixing bins and making it difficult to clean, making the mixing device more practical in use.

The model can be selected from the JO series. The input end of the mixing motor 109 is electrically connected to the output end of the control button 101. The output end of the mixing motor 109 is equipped with a rotating shaft via a coupling. One end of the rotating shaft passes through the first mixing box 106 and the second mixing box 107 respectively and is fixed to the surface of the mixer 110. A dust collection box 117 is installed inside the device housing 1. A coarse dust filter screen 114 for dust filtration is installed inside the dust collection box 117. A PTFE-coated filter cartridge 115 is installed inside the dust collection box 117. The PTFE-coated filter cartridge 115 is made of polyester material and is located below the coarse dust filter screen 114. An activated carbon adsorption layer 116 is installed inside the dust collection box 117. Below the PTFE-coated filter cartridge 115, the inner wall of the dust collection box 117 is provided with through holes 113, which communicate with the interior of the dust collection box 117. A first blower 111 is installed on the surface of the top position of the dust collection box 117. The first blower 111 can be a VFC series model. The input end of the first blower 111 is electrically connected to the output end of the control button 101. The input end of the first blower 111 passes through the first mixing box 106 and extends into the interior of the first mixing box 106. The output end of the first blower 111 passes through the dust collection box 117 and extends into the interior of the dust collection box 117. A second blower 112 is installed on the surface of the top position of the dust collection box 117. The second blower 112 can be a VFC series model.The input terminal of the second blower 112 is electrically connected to the output terminal of the control button 101. The input terminal of the second blower 112 passes through the second mixing box 107 and extends into the interior of the second mixing box 107. The output terminal of the second blower 112 passes through the dust collection box 117 and extends into the interior of the dust collection box 117. Both the inner walls of the first mixing box 106 and the second mixing box 107 have discharge holes 118 for discharging materials. Valves 119 are fitted onto the surfaces of both the first mixing box 106 and the second mixing box 107. The valves 119 can be of the TM series. The input terminal of the valve 119 is electrically connected to the output terminal of the control button 101.

[0022] Furthermore, such as Figure 2 and Figure 4 As shown, the inner walls of the mixer 110, the first mixing box 106, and the second mixing box 107 are all equipped with a scraping and anti-sticking mechanism 3. The scraping and anti-sticking mechanism 3 includes a scraper 31, a guide groove 32, a scraper frame 33, and an elastic device 34. The first mixing box 106 and the second mixing box 107 are both equipped with a scraper frame 33. The surface of the scraper frame 33 is fixed to the surface of the mixer 110. The scraper 31 is installed inside the scraper frame 33. One side of the scraper 31 extends to the outside of the scraper frame 33 and contacts the inner walls of the first mixing box 106 and the second mixing box 107. The inner walls of the scraper frame 33 are all provided with a guide groove 32. The guide groove 32 slides and engages with the surface of the scraper 31. The inner walls of the scraper frame 33 are all equipped with equally spaced elastic devices 34. One end of the elastic device 34 is fixed to the surface of the scraper 31.

[0023] In practice, when the mixer 110 rotates inside the first mixing box 106 and the second mixing box 107, the mixer 110 drives the scraper frame 33 and the scraper plate 31 to rotate inside the first mixing box 106 and the second mixing box 107. At this time, under the elastic force of the elastic device 34 inside the scraper frame 33, the scraper plate 31 moves inside the scraper frame 33. The scraper plate 31 slides inside the guide groove 32. Under the action of the guide groove 32, the scraper plate 31 is guided. Under the action of the elastic device 34, the scraper plate 31 always moves until it contacts the inner wall of the first mixing box 106 and the second mixing box 107. Under the joint action of the scraper plate 31 and the scraper frame 33, the material adhering to the inner wall of the first mixing box 106 and the second mixing box 107 can be scraped off, so as to realize the function of the mixing device scraping off the material adhering to the inner wall of the first mixing box 106 and the second mixing box 107.

[0024] Furthermore, such as Figure 2 and Figure 5As shown, both the device housing 1 and the dust collection box 117 are equipped with an automatic back-blowing mechanism 4. The automatic back-blowing mechanism 4 contains a timer 41, a pressure monitor 42, and an automatic back-blowing component 43. The automatic back-blowing component 43 is located on the surfaces of the device housing 1 and the dust collection box 117. The automatic back-blowing component 43 consists of a back-blowing box 431, a fan body 432, a controller 433, and a flow monitor 434. The back-blowing box 431 is screwed onto the surface of the device housing 1, and the fan body 432 is mounted on the surface of the back-blowing box 431. The fan body 432 can be a Y-series model, and its input end penetrates through the dust collection box 117. The output end of the blower body 432 extends through the backflushing box 431 and into the backflushing box 431. A pressure monitor 42 and a flow monitor 434 are installed inside the backflushing box 431. A timer 41 and a controller 433 are installed inside the backflushing box 431. The output end of the controller 433 is electrically connected to the input end of the blower body 432. An airflow distribution valve is installed on the surface of the blower body 432. The airflow distribution valve can be of the TM series. The input end of the airflow distribution valve is electrically connected to the output end of the control button 101.

[0025] In implementation, the back-blowing box 431 is installed at a designated position on the surface of the device housing 1 using screws. The blower body 432 reverses the airflow and sends it into the surface of the PTFE-coated filter cartridge 115 inside the dust collection box 117, forcing the dust and impurities adhering to the surface of the PTFE-coated filter cartridge 115 to fall off, thereby restoring dust collection efficiency. The compressed air is distributed to each back-blowing nozzle as needed via the airflow distribution valve. This ensures that the PTFE-coated filter cartridges 115 in different positions are cleaned evenly. Under the action of the timer 41, the controller 433 is controlled to operate according to the actual needs of the equipment. The controller 433, in turn, controls the blower body 432 to perform back-blowing. The timer 41 helps the control system to rationally allocate back-blowing time, avoiding over- or under-cleaning. The pressure monitor 42 monitors the pressure inside the dust collection box 117, and the flow monitor 434 monitors the flow rate inside the back-blowing box 431, thus realizing the automatic back-blowing function of the mixing device.

[0026] Working principle: In use, first place the device housing 1 in the designated position. The user introduces the materials to be mixed into the first mixing tank 106 and the second mixing tank 107 through the feed cylinder 105. The user operates the control button 101 on the surface of the device housing 1, which controls the mixing motor 109 to work. Under the action of the mixing motor 109, the mixer 110 rotates inside the first mixing tank 106 and the second mixing tank 107. Under the combined action of the mixing motor 109 and the mixer 110, the contents of the first mixing tank 106 and the second mixing tank 107 are mixed. Subsequently, when When materials are mixed inside the first mixing bin 106 and the second mixing bin 107, some dust is generated. The user then operates the control button 101 on the surface of the device body 1, which controls the first blower 111 and the second blower 112 on the surface of the dust collection bin 117 to operate. Under the combined action of the first blower 111 and the second blower 112, the dust inside the first mixing bin 106 and the second mixing bin 107 is drawn into the dust collection bin 117. Under the action of the coarse dust filter 114, the coarse dust in the dust is filtered, which can quickly remove larger dust particles, such as particles larger than fifty micrometers. This stage mainly reduces the burden on subsequent filter elements and extends the service life of the filter elements. Under the action of the PTFE coated filter cartridge 115, fine dust as small as one micrometer can be removed. This filter cartridge is not easily clogged during the filtration process and has strong high temperature resistance and corrosion resistance, making it suitable for different working environments. With the help of the activated carbon adsorption layer 116, it adsorbs and removes harmful gases such as volatile organic compounds (VOCs) and odors from the air. The first blower 111 and the second blower 112 adjust the airflow rate according to different working conditions. The blower speed is adjusted in real time based on dust concentration feedback to ensure maximum dust capture efficiency and reduce energy consumption. For airflow that cannot be recovered, the backflushing airflow can be discharged outside the dust collection box 117 through the through hole 113. Subsequently, the user operates the control button 101, which controls the valves 119 on the surface of the first mixing box 106 and the second mixing box 107 to operate, allowing the materials inside the first mixing box 106 and the second mixing box 107 to be discharged.

[0027] Subsequently, the back-blowing box 431 is installed at a designated position on the surface of the device housing 1 using screws. The fan body 432 then reverses the airflow and sends it into the surface of the PTFE-coated filter cartridge 115 inside the dust collection box 117, forcing the dust and impurities adhering to the surface of the PTFE-coated filter cartridge 115 to fall off, thereby restoring dust collection efficiency. The compressed air is then distributed to each back-blowing nozzle as needed via the airflow distribution valve. This ensures that the PTFE-coated filter cartridge 115 in different positions is cleaned evenly. Under the action of the timer 41, the controller 433 can be controlled to operate according to the actual needs of the equipment, and the controller 433 controls the fan body 432 to perform back-blowing. Timer 41 helps the control system to allocate backflushing time reasonably, avoiding excessive or insufficient cleaning. Under the action of pressure monitor 42, it can monitor the pressure inside dust collection box 117, and under the action of flow monitor 434, it can monitor the flow inside backflushing box 431, so as to realize the automatic backflushing function of mixing device. This allows the mixing device to clean the dust filtered on the surface of PTFE coated filter cartridge 115 when in use, avoiding damage to PTFE coated filter cartridge 115 by excessive airflow, and ensuring the cleaning effect on the surface of PTFE coated filter cartridge 115.

[0028] Subsequently, when the mixer 110 rotates inside the first mixing box 106 and the second mixing box 107, the mixer 110 drives the scraper frame 33 and the scraper plate 31 to rotate inside the first mixing box 106 and the second mixing box 107. At this time, under the elastic force of the elastic device 34 inside the scraper frame 33, the scraper plate 31 moves inside the scraper frame 33. The scraper plate 31 slides inside the guide groove 32, and is guided by the guide groove 32. Under the action of the elastic device 34, the scraper plate 31 always moves to the first mixing box 106 and the second mixing box 107. The inner walls of the material bin 106 and the second mixing bin 107 are in contact. Under the combined action of the scraper plate 31 and the scraper frame 33, the material adhering to the inner walls of the first mixing bin 106 and the second mixing bin 107 can be scraped off. This realizes the function of the mixing device to scrape off the material adhering to the inner walls of the first mixing bin 106 and the second mixing bin 107. This prevents the material from sticking to the inner walls of the first mixing bin 106 and the second mixing bin 107 and making it difficult to clean. This makes the mixing device more practical to use and finally completes the use of the mixing device.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
