Description

Technical Field

[0001] The present application relates to the technical field of plastic powder production, and in particular to a dust collection device for plastic powder production. Background Art

[0002] Plastic powder is a kind of plastic powder that can be coated on metal or non-metal surface through electrostatic spraying process. It can not only play a decorative and protective role, but also make the surface of objects smoother, flatter and more beautiful. Plastic powder also has good corrosion resistance, weather resistance and wear resistance, and can protect the surface of objects from erosion and damage from the external environment. Dust will be generated in the production process of plastic powder, which needs to be treated.

[0003] Application No. 202121278607.8 discloses a dust suction device for plastic powder production, including a device main body, a filter cloth, a lifting scraper and a nut rod, etc. Suction is generated by the nut rod, and the dust generated by the plastic powder production can be transported to the filter cloth through the device main body through the air inlet pipe. The hydraulic cylinder can drive the lifting scraper, and the lifting scraper can slide on the inner wall of the filter cloth to ensure that the filter cloth can continuously filter the dust, thereby improving the filtration efficiency. The first motor can drive the device shell to rotate, and the rotating device shell can discharge the dust in the annular groove into the recovery pipe through the blades, thereby realizing the automatic recovery of dust and improving work efficiency.

[0004] However, in use, there are the following defects:

[0005] Although a lifting scraper is used to scrape the dust on the surface of the filter cloth so that it falls into the annular groove for recovery, due to the light weight of the dust and the continuous flow of air in the device, part of the scraped dust will be stirred by the air and float around, unable to enter the annular groove, thus affecting the dust recovery efficiency of the device. Utility Model Content

[0006] The purpose of the present application is to provide a dust suction device for plastic powder production, which solves the problem proposed in the background technology that although a lifting scraper is used to scrape the dust on the surface of the filter cloth so that it falls into the annular groove for recovery, due to the light weight of the dust and the continuous flow of air in the device, part of the scraped dust will be stirred by the air and float around, unable to enter the annular groove, thereby affecting the dust recovery efficiency of the device.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a dust suction device for plastic powder production, comprising a box body, an outer filter frame, a scraper block, a cleaning plate and a distribution box, the left side wall of the box body is provided with an air inlet, and the right side wall of the box body is provided with an air outlet, the top of the box body is vertically inserted and connected with the outer filter frame, and the bottom of the outer filter frame is in contact with the inner bottom of the box body, a collecting trough is provided at the inner bottom of the box body on the left side of the outer filter frame, one end of the collecting trough is connected to the outer side wall of the box body, a filter screen is detachably installed on the inner side of the outer filter plate, and a No. 1 electric push rod is fixedly installed on the top surface of the box body on the left side of the outer filter plate, and the bottom of the No. 1 electric push rod is located at the inner side of the box body and is fixedly connected with a scraper block.

[0008] In this technical solution, air containing dust enters the box through the air inlet. The outer filter frame is an insertable design. The filter on the outer filter frame can intercept the dust and is provided with two layers of filters. When one of the filters needs to be pulled out for cleaning, the other filter can continue to work, thereby improving the continuous use efficiency of the device. Dust can be collected through the No. 1 electric push rod, scraper block, atomizing nozzle and collection tank. The water in the water inlet pipe is sprayed through the atomizing nozzle and can combine with the dust in the air to make it easier to collect. The scraper block is driven to move downward after the No. 1 electric push rod is powered on. Since the scraper block fits the surface of the filter, the dust on the surface of the filter is removed during the downward movement. The dust is scraped off, and the dust mixed with water droplets can avoid being scraped again, and finally fall into the collection trough below. In addition, the width of the scraper block is consistent with the collection trough, so the dust in the collection trough can be compacted, which is more convenient for collection, thereby improving the dust collection efficiency of the device. At the same time, the collected dust can be quickly exported through the No. 2 electric push rod, cleaning plate and sealing plug. When the collection trough needs to be cleaned, the sealing plug is pulled out, and then the No. 2 electric push rod is started to drive the cleaning plate to move toward the opening of the collection trough. Since the cleaning plate fits the inner wall of the collection trough, the collection trough can be scraped clean during the movement, so that the compacted dust is discharged from the opening, thereby improving the cleaning efficiency and practicality of the device.

[0009] As an optional solution of the technical solution of the present application, a water inlet pipe is passed through the upper center of the outer wall of the box body, and a plurality of atomizing nozzles are evenly and fixedly installed on the surface of the water inlet pipe located on the inner side of the box body.

[0010] As an optional solution to the technical solution of the present application, a No. 2 electric push rod is fixedly installed on the outer wall of the box body facing the other end of the collecting trough, and the end of the No. 2 electric push rod located on the inner side of the box body is fixedly connected to the cleaning plate, and the cleaning plate is located on the inner side of the collecting trough and fits against the inner wall of the collecting trough.

[0011] As an optional solution of the technical solution of the present application, the collecting tank is movably connected with a sealing plug at the opening of the outer side wall of the box body.

[0012] As an optional solution to the technical solution of the present application, an exhaust fan is fixedly installed on the right side wall of the box body at the air outlet opening.

[0013] As an optional solution to the technical solution of the present application, a distribution box is fixedly installed on the outer wall of the box body between the second electric push rods.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] 1. The present application can collect dust through the No. 1 electric push rod, scraper block, atomizing nozzle and collecting trough. The water in the water inlet pipe is sprayed out along the atomizing nozzle, which can combine with the dust in the air to make it easier to collect. The scraper block is driven to move downward after the No. 1 electric push rod is powered on. Since the scraper block fits the surface of the filter, the dust on the surface of the filter is scraped off during the downward movement. The dust mixed with water droplets can avoid being scraped again and finally fall into the collecting trough below. In addition, the width of the scraper block is consistent with the collecting trough, so the dust in the collecting trough can be compacted, which is more convenient to collect, thereby improving the dust collection efficiency of the device.

[0016] 2. The present application can quickly export the collected dust through the No. 2 electric push rod, the cleaning plate and the sealing plug. When the collection tank needs to be cleaned, the sealing plug is pulled out, and then the No. 2 electric push rod is started to drive the cleaning plate to move toward the opening of the collection tank. Since the cleaning plate fits the inner wall of the collection tank, the collection tank can be scraped clean during the movement, and the compacted dust is discharged from the opening, thereby improving the cleaning efficiency and practicality of the device.

[0022] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0023] like Figure 1 As shown, a dust suction device for plastic powder production includes a box body 1, an outer filter frame 7, a scraper block 10, a cleaning plate 13 and a distribution box 15. The left side wall of the box body 1 is provided with an air inlet 4.

[0024] like Figure 2 As shown, an air outlet 5 is provided on the right side wall of the box body 1, an outer filter frame 7 is vertically inserted and connected to the top of the box body 1, and the bottom of the outer filter frame 7 is in contact with the inner bottom of the box body 1, and a collecting groove 11 is provided on the inner bottom of the box body 1 on the left side of the outer filter frame 7, and one end of the collecting groove 11 is connected to the outer side wall of the box body 1, a filter screen 8 is detachably installed on the inner side of the outer filter plate, and the outer filter frame 7 can be freely inserted, so as to facilitate the replacement and cleaning of the filter screen 8.

[0025] like Figure 2 As shown, a No. 1 electric push rod 9 is fixedly installed on the top surface of the box body 1 on the left side of the outer filter plate. The bottom of the No. 1 electric push rod 9 is located on the inner side of the box body 1 and is fixedly connected with a scraper block 10. The scraper block 10 fits the surface of the filter screen 8 to facilitate scraping.

[0026] like Figure 2 As shown, an exhaust fan 6 is fixedly installed on the right side wall of the box body 1 at the opening of the air outlet 5, and the exhaust fan 6 draws air to the outside of the box body 1, thereby continuously introducing air containing dust.

[0027] like Figure 1 and Figure 2 As shown, a water inlet pipe 2 penetrates the upper center of the outer wall of the box body 1, and a plurality of atomizing nozzles 3 are evenly and fixedly installed on the surface of the water inlet pipe 2 located on the inner side of the box body 1. The atomizing nozzles 3 spray water droplets, thereby facilitating the combination with dust.

[0028] like Figure 3 As shown, a No. 2 electric push rod 12 is fixedly installed on the outer wall of the box body 1 facing the other end of the collecting tank 11, and one end of the No. 2 electric push rod 12 located on the inner side of the box body 1 is fixedly connected to a cleaning plate 13, and the cleaning plate 13 is located on the inner side of the collecting tank 11 and fits against the inner wall of the collecting tank 11, and the collecting tank 11 is movably connected with a sealing plug 14 at the start position of the outer wall of the box body 1, and a distribution box 15 is fixedly installed on the outer wall of the box body 1 between the No. 2 electric push rod 12.

[0029] During actual use, air containing dust enters the box body 1 along the air inlet 4. The outer filter frame 7 is of plug-in design. The filter 8 on the outer filter frame 7 can intercept dust and is provided with two layers of filter screens 8. When one of the filter screens 8 needs to be pulled out for cleaning, the other filter screen 8 can continue to work, thereby improving the continuous use efficiency of the device. Dust can be collected by the No. 1 electric push rod 9, the scraper block 10, the atomizing nozzle 3 and the collecting tank 11. The water in the water inlet pipe 2 is sprayed along the atomizing nozzle 3 and can combine with the dust in the air, making it easier to collect. The scraper block 10 is driven to move downward after the No. 1 electric push rod 9 is powered on and started. Since the scraper block 10 fits the surface of the filter screen 8, the dust on the surface of the filter screen 8 is scraped off during the downward movement. The dust mixed with water droplets can avoid being scraped again and finally fall into the collecting groove 11 below. The width of the scraper block 10 is consistent with that of the collecting groove 11, so the dust in the collecting groove 11 can be compacted, which is more convenient for collection, thereby improving the dust collection efficiency of the device. At the same time, the collected dust can be quickly exported through the No. 2 electric push rod 12, the cleaning plate 13 and the sealing plug 14. When the collecting groove 11 needs to be cleaned, the sealing plug 14 is pulled out, and then the No. 2 electric push rod 12 is started to drive the cleaning plate 13 to move toward the opening of the collecting groove 11. Since the cleaning plate 13 fits the inner wall of the collecting groove 11, the inside of the collecting groove 11 can be scraped clean during the movement, so that the compacted dust is discharged from the opening, thereby improving the cleaning efficiency and practicality of the device.
