[0024] As shown in the attached Figure 1 to the attached Figure 4 figure:

[0025] Embodiment:

[0026] The present invention provides a technical solution: a double-draft and double-recovery plastic powder room, including a box body 1 for processing plastic powder, a processing chamber 2 installed at both ends of the box body 1, and an air outlet 3 installed at one end of the processing chamber 2; an inlet 6 installed at the top of the box body 1, and support frames 5 are respectively installed on both sides of the lower end of the box body 1, and the volume of the box body 1 is greater than the volume of the inlet 6. The processing chamber 2 is used for screening and processing plastic powder; the air outlet 3 is used for exhausting air; through grooves communicating with the processing chamber 2 are provided on both sides of the box body 1.

[0027] More specifically:

[0028] I. Feeding: Plastic powder enters the interior of the box body 1 through the inlet 6 at the top of the box body 1.

[0029] II. Screening and processing: Plastic powder is sent into the processing chamber 2 inside the box body 1. There is a screening device inside the processing chamber 2 for separating powders of different particle sizes or components in the plastic powder.

[0030] III. Double exhaust system: Air outlets 3 are provided at both ends of the processing chamber 2, and exhaust systems are installed at both ends of the processing chamber 2. This design can improve the processing efficiency because exhausting air from both ends simultaneously can remove the processed plastic powder from the processing chamber 2 more quickly.

[0031] IV. Recycling: The processed plastic powder is discharged through the air outlet 3. Due to the double exhaust design, there are two recycling systems working simultaneously, corresponding to the air outlets 3 at both ends of the processing chamber 2 respectively, so that plastic powders with different particle sizes or compositions can be collected separately at the same time.

[0032] V. Through slot design: Through slots communicating with the processing chamber 2 are provided on both sides of the box body 1 to ensure that the plastic powder can flow smoothly from the box body 1 to the processing chamber 2.

[0033] VI. Support: Support frames 5 are respectively installed on both sides at the lower end of the box body 1 to support the weight of the entire box body 1 and ensure the structural stability.

[0034] VII. Volume design: The volume of the box body 1 is larger than that of the feed inlet 6. There is enough space inside the box body 1 to accommodate the plastic powder, and a certain amount of powder can be accommodated during the processing to ensure the continuity and efficiency of the processing process.

[0035] The design of this double exhaust and double recycling plastic powder house aims to achieve the rapid processing and effective recycling of plastic powder through efficient screening processing and a double exhaust system.

[0036] During implementation: The processing chamber 2 further includes a blower 21 fixedly installed inside it, a screening device, and a recycling pipeline 4 installed at the lower end. The blower 21 is fixedly installed at one end of the processing chamber 2 through a bracket. The screening device is located on one side of the blower 21. The screening device includes several groups of filters installed at intervals, and movable slots 28 for installing the filters are provided on the inner wall of the processing chamber 2. Sliders 29 are slidably connected in the movable slots 28, and both ends of the filter are respectively fixedly connected to the sliders 29. The lower end of the processing chamber 2 is provided with discharge openings 26 at equal intervals. The discharge openings 26 are respectively corresponding to one side of the lower end of the filters, and the upper end of the recycling pipeline 4 is communicated with the discharge openings 26.

[0037] More specifically: There are at least three groups of filter screens, namely the first filter screen 22, the second filter screen 23, and the third filter screen 24. The three groups of filter screens are movably connected by a guide shaft 27 in the middle. The other end of the guide shaft 27 is connected to the central shaft of the fan 21 through a bearing. The filter screen apertures of the first filter screen 22, the second filter screen 23, and the third filter screen 24 gradually become smaller. The fan 21 is used to provide power to help the plastic powder flow and be screened in the processing chamber 2. The slider 29 can slide in the movable groove 28. Such a design enables the first filter screen 22, the second filter screen 23, and the third filter screen 24 to move or vibrate within a small range under the action of the fan 21 within the range of the movable groove 28. In this way, the residual powder on the filter screen will be vibrated off and fall into the lower material discharge port 26. The filter screen apertures of the first filter screen 22, the second filter screen 23, and the third filter screen 24 gradually become smaller. This means that the plastic powder is first screened by the first filter screen 22 with the largest aperture, and then further screened by the second filter screen 23 and the third filter screen 24 with smaller apertures, achieving the collection effect of step-by-step screening. The screened plastic powder can be collected through the material discharge port 26. The screened plastic powder can directly enter the recovery pipeline 4 through the material discharge port 26 to realize the recovery of the plastic powder. Driven by the fan 21, the plastic powder is gradually screened through the filter screen of the screening device. According to different particle sizes, the screened plastic powder falls into the recovery pipeline 4 through the corresponding material discharge port 26. By arranging an external recovery box at the lower end of the recovery pipeline 4, plastic powders with different particle sizes can be separately collected and recovered to realize the effective utilization of resources, and the recovery box is convenient for storage.

[0038] During implementation: The fan 21 is installed near one end of the air outlet 3, and the air outlet 3 further includes an air outlet grille 31 installed at one of its ends.

[0039] More specifically: The function of the air outlet grille 31 is to prevent powder from being discharged at the air outlet 3.

[0040] During implementation: The apertures of several groups of the filter screens gradually become smaller, and the inner diameter of the air outlet 3 gradually becomes smaller.

[0041] More specifically: This enables the powder to be fully screened and filtered within the filter screen and the air outlet 3.

[0042] During implementation: The number of the material discharge ports 26 is the same as that of the filter screens and the recovery pipeline 4.

[0043] More specifically: This can enable the dust screened step by step to enter the corresponding recovery pipeline 4 for discharging and being collected one by one.

[0044] Working principle: Plastic powder enters the interior of the box body 1 through the top feed port 6 of the box body 1 and is sent into the processing chamber 2 inside the box body 1. Inside the processing chamber 2, there is a screening device composed of several groups of filters installed at intervals (at least three groups, such as the first filter screen 22, the second filter screen 23, and the third filter screen 24). The filter screens slide in the movable groove 28 through the sliders 29 and can move or vibrate within a small range under the action of the fan 21 to help the residual powder fall off. The fan 21 is installed at one end of the processing chamber 2 to provide power for the flow and screening of the plastic powder. The plastic powder is first screened by the first filter screen 22 with the largest aperture, and then further screened by the second filter screen 23 and the third filter screen 24 with smaller apertures in sequence. Air outlets 3 are respectively arranged at both ends of the processing chamber 2, and there is an air extraction system at both ends, which can simultaneously remove the processed plastic powder from the processing chamber 2. The powder discharged through the air outlet 3 passes through the air outlet grille 31 to prevent the powder from escaping. The through grooves on both sides of the box body 1 ensure that the plastic powder can smoothly flow from the box body 1 to the processing chamber 2. The processed plastic powder falls into the recovery pipeline 4 through the corresponding discharge ports 26 according to different particle sizes. The plastic powder with different particle sizes is separately collected and recycled, and the lower end of the recovery pipeline 4 is connected to an external recovery box.
