[0031] See also Figure 1-5 The utility model provides a technical solution: a dust precipitation device for plastic powder, comprising a filter box 1, a connecting pipe 2 connected to the top of the filter box 1 with a flange, and a sealing door 3 hingedly mounted on the side of the filter box 1, wherein the connecting pipe 2 is provided with a valve, and the sealing door 3 is fixedly mounted with a handle 4. A filter assembly 5 is provided inside the filter box 1, and the filter assembly 5 includes a slide rod 51, a slider 52 and a first filter plate 53. The slide rod 51 is divided into two groups and is arranged in an upper and lower position. One end of the slide rod 51 is fixedly mounted on the inner wall of one side of the filter box 1, and the other end is fixedly mounted on the inner wall of the filter box 1. The sealing door 3 is fitted together, and sliders 52 are slidably installed on the two sets of sliding rods 51. The top and bottom of the sliders 52 are both snap-connected with the first filter plate 53. In order to ensure the filtering effect, the first filter plate 53 can be replaced after multiple uses. The specific operation is as follows: first open the sealing door 3, then pull the first filter plate 53, so that the first filter plate 53 drives the slider 52 to slide on the sliding rod 51 until the slider 52 is out of the sliding rod 51, and then take out the first filter plate 53 to achieve cleaning or replacement of the first filter plate 53. The operation is simple and convenient.

[0032] The first filter plate 53 is a HEPA filter layer. The first filter plate 53 can filter the dust for the first time, thereby absorbing impurities such as tiny particles in the dust, thereby achieving a filtering effect.

[0033] The filter assembly 5 also includes multiple sets of sealing gaskets 54 fixedly installed on the inner wall of the filter box 1 and the inner wall of the sealing door 3. The outer wall of the first filter plate 53 and the sealing gasket 54 are fitted together. This setting ensures the sealing effect of the first filter plate 53 in the filter box 1 and prevents dust from not passing through the first filter plate 53.

[0034] The bottom of the filter box 1 is fixedly installed with a support leg 6, and a sedimentation box 7 is fixedly installed between the support legs 6. The bottom flange of the filter box 1 is connected with a connecting pipe 8. The free end of the connecting pipe 8 passes through the sedimentation box 7. A valve is provided on the connecting pipe 8.

[0035] It should be noted that the rear flange of the sedimentation box 7 is installed with a water inlet pipe and a water outlet pipe, which are not drawn in the figure. Liquid is injected into the sedimentation box 7 to facilitate subsequent dust precipitation.

[0036] An exhaust pipe 9 is installed on the outer wall flange of one side of the sedimentation box 7. A processing component 10 is provided on one side of the sedimentation box 7. The processing component 10 includes a shell 101, a spring 102, a connecting block 103 and a second filter plate 104. The shell 101 is fixedly installed on the bottom of the filter box 1, and a reserved door is provided on the rear side of the shell 101 to facilitate the installation of the component, which is not drawn in the figure.

[0037] A spring 102 is fixedly installed on the inner wall of one side of the shell 101, and a connecting block 103 is slidably installed inside the shell 101. The free end of the spring 102 is fixedly connected to the connecting block 103. An opening is provided at the bottom of the shell 101, and a second filter plate 104 is fixedly connected to the bottom of the connecting block 103. The second filter plate 104 is an activated carbon sponge layer. The second filter plate 104 and the exhaust pipe 9 are fitted together. When there is a lot of dust on the second filter plate 104, the connecting block 103 can be pushed so that the connecting block 103 compresses the spring 102, canceling the fitting state of the second filter plate 104 and the exhaust pipe 9, thereby facilitating the cleaning of the positive side of the second filter plate 104, thereby ensuring the filtering effect of the second filter plate 104.

[0038] The processing component 10 also includes a protrusion 105 fixedly installed on the front side of the connecting block 103, which facilitates the adjustment of the connecting block 103 to facilitate the cleaning of the second filter plate 104. The device can effectively absorb and precipitate dust, effectively control the dust in the working environment, improve the cleanliness of the environment, and facilitate use.

[0039] When in use, the connecting pipe 2 is connected to the external dust collection device to absorb the powder dust into the filter box 1, and after being filtered by the first filter plate 53, it enters the sedimentation box 7 through the connecting pipe 8. The first filter plate 53 can filter the dust for the first time, thereby absorbing impurities such as tiny particles in the dust, thereby achieving a filtering effect;

[0040] The first filter plate 53 can be replaced after multiple uses. The specific operation is as follows: first, open the sealing door 3, then pull the first filter plate 53, so that the first filter plate 53 drives the slider 52 to slide on the slide rod 51 until the slider 52 is out of the slide rod 51, and then take out the first filter plate 53 to clean or replace the first filter plate 53;

[0041] The filtered dust enters the sedimentation box 7 for sedimentation, wherein the valve on the exhaust pipe 9 is opened, and the gas passes through the exhaust pipe 9 and is filtered by the second filter plate 104 and then discharged. When there is a lot of dust on the second filter plate 104, the connecting block 103 can be pushed so that the connecting block 103 compresses the spring 102, canceling the fitting state between the second filter plate 104 and the exhaust pipe 9, thereby facilitating the cleaning of the front side of the second filter plate 104, thereby ensuring the filtering effect of the second filter plate 104.
