[0054] Industrial coating is an indispensable and important part of the industrial production process. During the spraying operation, a large amount of paint mist, volatile organic compounds (VOCs) and other air pollutants will be generated. Such pollutants pose a great threat to human health, working environment and living environment. At the same time, they will also generate harmful gases that destroy the ozone layer, so they need to be recycled and processed.

[0055] In the prior art, a dry paint mist filter box is usually used to separate paint mist from volatile organic compounds (VOCs). After the paint mist and volatile organic compounds (VOCs) are separated by multiple layers of filter materials in the dry paint mist filter box, the volatile organic compounds (VOCs) are adsorbed by activated carbon or incinerated, thereby reducing pollutant emissions.

[0056] However, the filters in the current dry paint mist filter box need to be cleaned and replaced regularly to ensure filtration efficiency. The cleaning and replacement process usually requires workers to enter the paint mist filter box and complete it manually, which has low work efficiency and poses a safety risk in working in a confined space.

[0057] In view of this, the dry paint mist filtering device provided by the present application controls the flow rate of gas entering and exiting the box by respectively setting a first control valve and a second control valve at the two ports of the box, and installing a paint mist capture member, a first filter system, a filter replacement detection system and a second filter system in the box, and the first filter system has a plurality of first filters, and the second filter system has a plurality of second filters. In this way, multi-stage filtration of paint mist is achieved. At the same time, the first filter and the second filter are detected and replaced by the filter replacement detection system, and a vibration component is provided to achieve the cleaning of the paint mist capture member. Such a design solves the problem that the cleaning and replacement process of the filter in the existing dry paint mist filter box requires the staff to enter the paint mist filter box to complete it manually, the work efficiency is low, and there is a safety risk of working in a confined space.

[0058] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] Figure 1 A schematic diagram of the structure of a dry paint mist filtering device provided in an embodiment of the present application; Figure 2 for Figure 1 A partial enlarged view of the middle A; Figure 3 for Figure 1 A schematic diagram of the structure of the second filtering system; Figure 4 A schematic diagram of the structure of a filter replacement detection system in a dry paint mist filtering device provided in an embodiment of the present application; Figure 5 for Figure 4 A partial enlarged view of point B in the middle.

[0060] See also Figures 1 to 5The present application provides a dry paint mist filtering device, including a housing 100, a vibration assembly 200, a first filter system 300, a second filter system 400, a filter replacement detection system 500 and at least one paint mist capture member 600. The two ports of the housing 100 are respectively provided with a first control valve 110 and a second control valve 120. The first control valve 110 and the second control valve 120 are respectively used to control the flow rate of gas in and out. The paint mist capture member 600 is slidably installed in the housing 100 and is arranged close to the first control valve 110. The paint mist capture member 600 is used to For capturing paint mist particles; part of the vibration component 200 is located in the housing 100 and in contact with the paint mist capture component 600, and the vibration component 200 is used to vibrate and clean the paint mist capture component 600; the first filter system 300, the filter replacement detection system 500 and the second filter system 400 are sequentially installed in the housing 100, the first filter system 300 has a plurality of first filters 310, the second filter system 400 has a plurality of second filters 410, and the filter replacement detection system 500 is used to detect and replace the first filter 310 and the second filter 410.

[0061] In some embodiments, the box 100 is used for the installation of the vibration assembly 200, the first filter system 300, the second filter system 400, the filter replacement detection system 500 and at least one paint mist capture element 600. At the same time, the box 100 also acts as a filtering channel. It can be understood that the box 100 can adopt a pyramidal structure design with small ends and a large middle. Such a design reduces the wind speed of the paint mist particles when passing through the first filter system 300, the second filter system 400, and the filter replacement detection system 500, increases the residence time of the paint mist particles, and thus improves the filtration efficiency.

[0062] In a specific implementation, a first control valve 110 and a second control valve 120 are respectively provided at the two ports of the box body 100, and the first control valve 110 and the second control valve 120 are respectively located at the inlet and the outlet. During use, the first control valve 110 and the second control valve 120 can be adjusted by the control system, thereby controlling the flow rate of gas entering and exiting the box body 100 to reduce uneven airflow and box body vibration caused by filtration resistance. At the same time, the first control valve 110 and the second control valve 120 are provided at the two ports of the box body 100 to have a safety isolation function during fire, equipment maintenance, etc.

[0063] In order to capture the paint mist particles in the gas to be filtered, at least one paint mist capture member 600 is arranged in the box body 100, and a push-pull slide rail is provided on the paint mist capture member 600, which is detachably connected to the box body 100. Therefore, while the paint mist capture member 600 realizes the primary filtering effect, the detachable connection method also makes it convenient for the staff to check and replace the paint mist capture member 600, thereby ensuring the filtering effect of the paint mist capture member 600 on the paint mist particles.

[0064] It can be understood that the number and layout of the paint mist capture element 600 are given for exemplary purposes only and can be specifically set according to actual needs. That is to say, in a specific implementation, a plurality of paint mist capture elements 600 can be provided, and the mesh density of the capture net on the paint mist capture element 600 can be increased successively to achieve multi-stage filtration of paint mist particles.

[0065] Among them, part of the vibration component 200 is located in the box body 100 and is in contact with the paint mist capture component 600. When the vibration component 200 is started, part of the vibration component 200 can present regular mechanical vibration, and then transmit the vibration power to the paint mist capture component 600, so that the paint mist capture component 600 is shaken under the drive of the vibration component 200. As a result, the paint mist particles attached to the paint mist capture component 600 are fallen off by the shaking of the paint mist capture component 600, thereby ensuring the filtration efficiency of the paint mist capture component 600 and improving the service life of the paint mist capture component 600. At the same time, it ensures smooth ventilation inside the box body 100 and improves the operating stability of the device.

[0066] In the present application, the first filter system 300 and the second filter system 400 are installed in the box 100 in sequence. The first filter system 300 has a first filter 310, which can be a flat filter. The flat filter has a simple structure and high filtration efficiency. The second filter system 400 has a second filter 410, which can be a bag filter. The bag filter has the advantages of high filtration efficiency and low cost. Therefore, the paint mist particles in the gas are further filtered by the first filter 310 and the second filter 410, thereby further improving the filtration efficiency of the device.

[0067] It can be understood that both the first filter system 300 and the second filter system 400 adopt a modular structural design, that is, a plurality of first filters 310 of the same specifications are arranged in sequence on the first filter system 300, and a plurality of second filters 410 of the same specifications are arranged in sequence on the second filter system 400, thereby improving the versatility of the first filter 310 and the second filter 410.

[0068] In specific implementation, a filter replacement detection system 500 is provided between the first filter system 300 and the second filter system 400, and the filter replacement detection system 500 is detachably connected to the housing 100, thereby facilitating the filter replacement detection system 500 to detect the blockage condition of the first filter system 300 or the second filter system 400 respectively. The filter replacement detection system 500 checks the first filter 310 and the second filter 410 one by one, and accurately replaces the blocked first filter 310 and the second filter 410 according to the inspection results. Such a design greatly reduces the number of replacements and reduces the cost of paint mist filtering consumables.

[0069] It is understandable that the frames of the first filter 310 and the second filter 410 can be set to the same size. Such a design makes it easier for the filter replacement detection system 500 to grab the first filter 310 and the second filter 410 for replacement, thereby improving the replacement efficiency of the filter replacement detection system 500. At the same time, the modular structure design of the first filter system 300 and the second filter system 400 can improve the positioning accuracy of the automatic detection and replacement process of the filter replacement detection system 500. The filter replacement detection system 500 can realize automatic detection and replacement of the first filter 310 and the second filter 410, thereby replacing traditional manual detection and replacement, improving replacement efficiency and safety, and improving device automation.

[0070] In the present application, before the device is started, the paint mist generated by the spraying is first connected to the first control valve 110 through a pipeline, and the staff moves the paint mist capture member 600 out of the box 100 to check whether the paint mist capture member 600 is damaged. If it is damaged, a new paint mist capture member 600 is replaced. If it is not damaged, the paint mist capture member 600 is moved into the box 100, and then the device is powered on, and the first control valve 110 and the second control valve 120 are opened to allow the gas containing a large amount of paint mist generated during the spraying operation to enter the box 100 through the first control valve 110, and then the gas passes through the paint mist capture member 600, the first filter system 120, and the second filter system 120. 300 and the second filter system 400 are used to achieve step-by-step filtration of paint mist particles. The filtered gas enters the terminal treatment facility through the second control valve 120, and then the first filter 310 and the second filter 410 are detected and replaced through the filter replacement detection system 500. By setting a vibration component 200 and contacting with the paint mist capture component 600, the paint mist capture component 600 can be cleaned. This design solves the problem that the cleaning and replacement process of the filter in the existing dry paint mist filter box requires the staff to enter the paint mist filter box manually to complete it, the work efficiency is low, and there is a safety risk of working in a confined space.

[0071] See also Figure 2 , Figure 4 and Figure 5 In an embodiment of the present application, the filter replacement detection system 500 includes a replacement component 510, and the replacement component 510 includes a frame 511 and a storage rack 512 connected to the frame 511, the frame 511 is detachably connected to the box body 100, and the storage rack 512 is used to store each first filter 310 and each second filter 410.

[0072] Among them, the filter replacement detection system 500 includes a replacement component 510, which is used to realize the disassembly and installation of the first filter 310 and the second filter 410. The replacement component 510 includes a frame 511 and a storage rack 512 for storing each first filter 310 and each second filter 410, and the frame 511 has a slide so that the filter replacement detection system 500 can slide into or out of the box 100 through the slide. Such a design makes it easy for the staff to put the first filters 310 and the second filters 410 to be replaced into the storage rack 512 and take out the scrapped first filters 310 and the second filters 410 from the storage rack 512.

[0073] See also Figures 1 to 5 In the embodiment of the present application, the first filter system 300 also includes a first mounting frame 320 and a plurality of first connecting members 330, and the first filter 310 is installed on the first mounting frame 320 through the first connecting member 330; the second filter system 400 also includes a second mounting frame 420 and a plurality of second connecting members 430, and the second filter 410 is installed on the second mounting frame 420 through the second connecting member 430; a moving member 513 is slidably arranged on the frame 511, and a filter grabbing member 514 is installed on the moving member 513, and the filter grabbing member 514 is provided with at least two telescopic claws 515, and the telescopic claws 515 are used to install and disassemble the first connecting member 330 and the second connecting member 430, and grab the first filter 310 and the second filter 410 to store them in the storage rack 512.

[0074] In some embodiments, the first connecting member 330 and the second connecting member 430 can both use fixing bolts, whereby the first filter 310 and the second filter 410 are respectively installed on the first mounting frame 320 and the second mounting frame 420 by fixing bolts, and the fixing bolts are used instead of the traditional snap-in structure to prevent loosening.

[0075] It can be understood that the number and layout of the first connecting members 330 and the second connecting members 430 are only given for example, and can be specifically set according to actual needs, and this embodiment is not limited here.

[0076] Exemplarily, when it is necessary to inspect or replace the first filter 310, the staff sets the filter replacement detection system 500 toward the first filter system 300. When it is necessary to inspect or replace the second filter 410, the filter replacement detection system 500 is moved out of the box 100, the direction of the filter replacement detection system 500 is changed, and then it is moved back into the box 100 so that the filter replacement detection system 500 is set toward the second filter system 400. This facilitates the filter replacement detection system 500 to inspect or replace the first filter system 300 and the second filter system 400.

[0077] In order to install and disassemble the first connecting member 330 and the second connecting member 430 and grasp the first filter 310 and the second filter 410, a filter grasping member 514 is provided, and a telescopic claw 515 is provided on the filter grasping member 514. At the same time, the filter grasping member 514 is slidably set on the frame 511 through the moving member 513.

[0078] When the first filter 310 needs to be replaced, the filter grabbing member 514 is first moved to the position of the first filter 310 to be replaced through the control system through the moving member 513, and then the telescopic claw 515 is controlled to extend to the outside of the filter grabbing member 514, the first connecting member 330 is disassembled, and then the first filter 310 is removed from the first mounting frame 320, and the filter grabbing member 514 is rotated to place the first filter 310 on the storage rack 512, and then a new first filter 310 is grabbed from the storage rack 512 and placed in the corresponding position, and then the first connecting member 330 is installed to fix the first filter 310, and the replacement of the first filter 310 is completed. When the work is completed, the telescopic claw 515 can be retracted into the filter grabbing member 514.

[0079] Similarly, if the second filter 410 needs to be inspected or replaced, the filter replacement detection system 500 is reversed so that the filter grabbing member 514 is disposed toward the second filter 410, and then the above steps are repeated.

[0080] It is understandable that the number and layout of the telescopic claws 515 are only given for example, and can be specifically set according to actual needs, and this embodiment is not limited thereto.

[0081] See also Figure 1 , Figure 2 and Figure 5 In an embodiment of the present application, the filter replacement detection system 500 also includes a detection component 520, and the detection component 520 includes a blockage visual detection component 521, which is installed on the filter grabbing component 514, and the blockage visual detection component 521 is used to detect the blockage status of the first filter 310 and the second filter 410.

[0082] In the present application, in order to detect the blockage of the first filter 310 and the second filter 410, a blockage visual detection component 521 is provided. The blockage visual detection component 521 is installed on the filter grabbing component 514. When it is necessary to detect the first filter 310, the filter grabbing component 514 is set toward the first filter 310, and the first filter 310 is checked one by one by the blockage visual detection component 521. When blockage is found during the inspection, feedback is sent to the control system for recording, and then the first filter 310 is replaced by the replacement component 510 to improve the filtering effect of the first filtering system 300.

[0083] Similarly, if it is necessary to inspect the second filter 410, the filter replacement detection system 500 is reversed so that the filter grabbing member 514 is set toward the second filter 410, and the first filter 310 is inspected one by one through the blocked visual detection member 521. If any abnormality is found during the inspection, it is fed back to the control system for recording.

[0084] See also Figure 1 , Figure 2 and Figure 5 In the embodiment of the present application, the detection component 520 also includes a blowing member 522, a pressure sensor 523 and a sealing member. The sealing member is installed on the side of the filter grabbing member 514 facing away from the storage rack 512. The sealing member is used for the close contact between the filter grabbing member 514 and the second filter 410 to ensure the seal; the blowing member 522 is used to blow air into the second filter 410, and the pressure sensor 523 is used to detect the internal pressure of the second filter 410.

[0085] In specific implementation, after the inspection of the blockage visual detection component 521 is completed, the second filter 410 with an abnormal condition is further inspected, and the filter grabbing component 514 is moved to the abnormal second filter 410 by controlling the moving component 513, and the filter grabbing component 514 is tightly attached to the frame of the second filter 410, and a sealing component is provided on the filter grabbing component 514 to improve the sealing performance between the filter grabbing component 514 and the frame of the second filter 410, and then the blowing component 522 is started to blow air into the second filter 410 through the blowing component 522, and then the pressure in the second filter 410 is detected by the pressure sensor 523. If the pressure in the second filter 410 is too high, it means that the second filter 410 is blocked, and the blockage information is fed back to the control system for recording, and then the second filter 410 is replaced by the replacement component 510.

[0086] See also Figure 1 In the embodiment of the present application, a pressure detector 700 is provided between the first control valve 110 and the paint mist capture element 600, between the paint mist capture element 600 and the first filter system 300, between the first filter system 300 and the second filter system 400, and between the second filter system 400 and the second control valve 120. The pressure detector 700 is used to detect the pressure difference change of the gas after filtering by the paint mist capture element 600, the first filter system 300 and the second filter system 400.

[0087] It is understandable that, in order to facilitate real-time monitoring of the filtering effects of the paint mist capture member 600, the first filter system 300 and the second filter system 400, pressure detectors 700 are provided between the first control valve 110, the paint mist capture member 600, the first filter system 300, the second filter system 400 and the second control valve 120. Thus, the pressure detector 700 can be used to detect the pressure between the first control valve 110, the paint mist capture member 600, the first filter system 300, the second filter system 400 and the second control valve 120 in real time, and then calculate the pressure difference change. Thus, the filter status of the paint mist capture member 600, the first filter system 300 and the second filter system 400 can be detected in real time by the pressure detector 700, thereby avoiding the failure of the paint mist filtering device and the pollution to the environment caused by the filtering failure.

[0088] In some embodiments, the pressure detectors 700 between the paint mist capture element 600 and the first filter system 300, between the first filter system 300 and the second filter system 400, and between the second filter system 400 and the second control valve 120 monitor in real time the changes in the pressure difference before and after the first filter system 300 and before and after the second filter system 400. When the pressure difference is too large, the control system will control the first control valve 110 and the second control valve 120 to automatically close, and the first filter system 300 and the second filter system 400 will be detected by the filter replacement detection system 500. The abnormal conditions of the first filter system 300 and the second filter system 400 will be fed back to the control system through the filter replacement detection system 500 for recording, and the replacement of the first filter 310 and the second filter 410 will be achieved through the filter replacement detection system 500.

[0089] At the same time, during actual operation, the pressure detection gauge 700 between the first control valve 110 and the paint mist capture element 600 and between the second filter system 400 and the second control valve 120 can detect the pressure difference changes at both ends of the box 100 in real time, and the control system is used to adjust the flow rate of the first control valve 110 and the second control valve 120 to reduce the uneven airflow and box vibration caused by the filtration resistance, thereby improving the operation stability.

[0090] See also Figure 1 In the embodiment of the present application, the vibration assembly 200 includes a vibrator 210 and a vibration rod 220. The vibrator 210 is located at the top of the box 100, and the vibration rod 220 is located inside the box 100. One end of the vibration rod 220 is fixedly connected to the vibrator 210, and the other end is in contact with the paint mist capture member 600. The vibrator 210 drives the vibration rod 220 to vibrate, and the vibration rod 220 is used to vibrate and clean the paint mist particles on the paint mist capture member 600.

[0091] In the present application, in order to remove the paint mist particles attached to the paint mist capture member 600, avoid affecting the filtering effect of the paint mist capture member 600, and improve the service life of the paint mist capture member 600, a vibration assembly 200 is provided. The vibration assembly 200 includes a vibrator 210 and a vibration rod 220. The vibrator 210 is installed on the top of the box body 100, and the vibration rod 220 is located inside the box body 100. At the same time, one end of the vibration rod 220 is fixedly connected to the vibrator 210 to receive the vibration power from the vibrator 210, and the other end of the vibration rod 220 is in contact with the paint mist capture member 600, so that the paint mist capture member 600 can receive the vibration power from the vibration rod 220.

[0092] When the pressure detector 700 located between the first control valve 110 and the paint mist capture member 600 and between the paint mist capture member 600 and the first filter system 300 detects that the pressure difference before and after the paint mist capture member 600 is too large, it means that too many paint mist particles are attached to the paint mist capture member 600, causing the paint mist capture member 600 to be blocked. When it is detected that the paint mist capture member 600 is blocked or the set paint mist particle cleaning cycle is reached, the vibrator 210 is started through the control system, and the vibration rod 220 receives the vibration power transmitted by the vibrator 210 and performs regular mechanical vibration to drive the paint mist capture member 600 to shake, thereby shaking off the paint mist particles attached to the paint mist capture member 600, ensuring that the filtering effect of the paint mist capture member 600 is good and the gas flows smoothly in the box 100.

[0093] See also Figure 1 In the embodiment of the present application, a timing controller 211 is provided on the vibrator 210 , and the timing controller 211 is used to control the timing opening and closing of the vibrator 210 .

[0094] In a specific implementation, the timing controller 211 is fixedly installed on the vibrator 210. By using the timing controller 211, the vibration duration of the vibration component 200 and the interval of the vibration operation time can be set in advance to realize the timed start and stop of the vibrator 210, thereby improving the convenience of using the vibration component 200.

[0095] See also Figure 1 In the embodiment of the present application, a collecting component 800 is also included. The collecting component 800 is provided with a collecting pipe 810, a collecting bucket 820 and a sealing plate 830. The collecting pipe 810 is located at the bottom of the box body 100 and is connected to the box body 100. The paint mist particles enter the collecting bucket 820 through the collecting pipe 810 to collect the paint mist particles; the sealing plate 830 is slidably installed at the bottom of the box body 100, and the sealing plate 830 is used to control the airtightness of the box body 100 and the connection with the outside world.

[0096] In the present application, in order to centrally collect and process the paint mist particles shaken off the paint mist capture element 600 and avoid environmental pollution caused by the manual cleaning process of the paint mist particles, a collecting pipe 810 is arranged at the bottom of the box 100, and the collecting pipe 810 is connected to the box 100. The paint mist particles shaken off by the paint mist capture element 600 during vibration enter the collecting pipe 810 along the inner wall of the box 100. At the same time, a collecting bucket 820 is connected to the end of the collecting pipe 810. The paint mist particles enter the collecting bucket 820 via the collecting pipe 810, and thus the paint mist particles are collected by the collecting bucket 820.

[0097] It can be understood that a sealing plate 830 is slidably installed at the bottom of the box 100. When it is necessary to vibrate and separate the paint mist particles attached to the paint mist capture member 600, the sealing plate 830 needs to be opened while starting the vibration component 200. In this way, smooth circulation inside the box 100 can be ensured, and the resistance inside the box 100 can be reduced, so that the vibration can be more effectively transmitted to the paint mist capture member 600, thereby promoting the shedding of the paint mist particles. When the cleaning is completed, the sealing plate 830 is closed to ensure the sealing of the box 100, and then the collection bucket 820 is removed, and the paint mist particles in the collection bucket 820 are transferred to the hazardous waste temporary storage room for treatment.

[0098] See also Figure 1 In the embodiment of the present application, a paint mist detector 130 is installed in the box 100. The paint mist detector 130 is located at the front end of the second control valve 120. The paint mist detector 130 is used to detect the paint mist particle content in the filtered gas.

[0099] Among them, a paint mist detector 130 is arranged at the front end of the second control valve 120. The filtered gas enters the terminal treatment facility through the second control valve 120 after being detected as qualified by the paint mist detector 130. When the paint mist detector 130 detects that the paint mist particle content in the filtered gas is unqualified, the control system controls the first control valve 110 and the second control valve 120 to close in sequence, suspends the paint mist filtering, and inspects the paint mist filtering device to prevent the emission of substandard gas from polluting the environment.

[0100] In summary, the dry paint mist filtering device provided by the present application is provided with a first control valve 110 and a second control valve 120 at two ports of the box 100 to control the flow rate of gas entering and exiting the box 100, and a paint mist capture member 600, a first filter system 300, a filter replacement detection system 500, and a second filter system 400 are installed in the box 100, and the first filter system 300 has a plurality of first filters 310, and the second filter system 400 has a plurality of second filters 410. Thus, multi-stage filtration of paint mist is achieved. At the same time, the first filter 310 and the second filter 410 are detected and replaced by the filter replacement detection system 500, and the paint mist capture member 600 is cleaned by setting a vibration assembly 200. Such a design solves the problem that the cleaning and replacement process of the filter in the existing dry paint mist filter box requires the staff to enter the paint mist filter box to complete it manually, the work efficiency is low, and there is a safety risk of working in a confined space.
