Furthermore, based on testing standards such as GB / T 4208, the number of times the dust used in the test can be used should not exceed 20 times. Therefore, when switching to a different type of dust, the disposal of dust that has not yet reached its usage limit becomes a major challenge, easily leading to a waste of testing resources and increased testing costs.
[0004] This application provides a dustproof test chamber device that can reuse dust, and adopts the following technical solution:
[0005] A dustproof test chamber device for reusable dust includes a test chamber, a collection funnel, a first tube, a blower, a dust return pipe, a transfer box, a movable box, and a dust collection assembly.

[0013] In summary, this application includes at least one of the following beneficial technical effects:
[0014] This device uses two sets of switchable movable chambers to store different types of dust. When switching tests is required, the dust can be temporarily stored in one chamber while the other chamber is filled with new dust for the next test, avoiding the direct disposal of unused dust, reducing dust waste, and lowering testing costs. Through the closed-loop operation of the blower, dust return pipe, and transfer chamber, the dust after testing can be collected back into the transfer chamber and then sorted and stored in the movable chambers, enabling multiple reuses of the same type of dust. Furthermore, a stepper motor drives a sliding bracket to move the movable chambers laterally, allowing for rapid switching between different dust chambers. A folded corrugated pipe is installed at the bottom of the movable chamber to compensate for pipe displacement during movement and prevent dust leakage. An electric telescopic rod pushes a dust-pushing plate to thoroughly clean residual dust in the transfer chamber, ensuring no cross-contamination between different dust types. It should be noted that if the number of times the dust has been used in the dustproof test reaches the usage limit specified in the testing standard, the test dust in the corresponding dust chamber must be replaced; it cannot be reused.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0028] This application discloses a dustproof test chamber device that can reuse dust. (Refer to...) Figures 1 to 5 The dustproof test chamber device for reusable dust includes a test chamber 1, a collection funnel 2, a first tube 3, a blower 4, a dust return pipe 5, a transfer box 6, a movable box 7, and a dust collection assembly 8.

The transfer box 6 is fixedly connected to the bottom of the first tube 3. The movable box 7 is slidably connected to the bottom of the discharge port of the transfer box 6. The dust collection assembly 8 is installed on the outer side of the movable box 7. The two sides of the dust return pipe 5 pass through the inner walls of the test chamber 1 and the transfer box 6 respectively and are tightly fitted to the inner walls of the test chamber 1 and the transfer box 6. The blower 4 is installed on the outer side of the dust return pipe 5.
[0029] Two sets of movable boxes 7 are provided, and the two sets of movable boxes 7 are movably connected to the bottom of the transfer box 6 and are used to store different types of dust separately.
[0030] The dust collection assembly 8 includes an inner grooved support plate 81, a sliding bracket 82, a connecting frame 83, a stepper motor 84, and a locking gear 85. The inner grooved support plate 81 is fixedly connected to the bottom inner side of the test chamber 1. The sliding bracket 82 is slidably connected to the outer side of the inner grooved support plate 81. The connecting frame 83 is fixedly connected to the outer side of the sliding bracket 82, and the top of the connecting frame 83 is fixedly connected to the surface of the movable box 7. The stepper motor 84 is installed on the top of the sliding bracket 82, and the locking gear 85 is fixedly connected to the lower part of the motor shaft of the stepper motor 84.
[0031] The inner side of the groove of the inner grooved support plate 81 is also provided with a transverse rack 9 that meshes with the external teeth of the locking gear 85.
[0032] The bottom outer side of the movable box 7 is also provided with a movable tube 10, a second tube 11 and a folded corrugated pipe 12. The folded corrugated pipe 12 is snapped onto the outside of the opening of the movable tube 10 and the second tube 11 and is used to compensate for the displacement of the movable box 7 in the sliding state. The output end of the second tube 11 is welded to the inner surface of the dust return pipe 5.
[0033] The outer side of the second pipe 11 is also fitted with a discharge valve 13 for discharging dust.
[0034] The outer side of the transfer box 6 is also provided with a flared bracket 14, an electric telescopic rod 15 and a ash pusher 16. The flared bracket 14 is fixedly connected to the outer side of the transfer box 6, the electric telescopic rod 15 is installed in the middle of the flared bracket 14, and the ash pusher 16 is fixedly connected to the outer side of the output end of the electric telescopic rod 15, and the ash pusher 16 is slidably connected to the inside of the transfer box 6.
[0035] A control panel 17 is also installed on the outside of the test chamber 1.
[0036] The usage process of the dustproof test chamber device for reusable dust according to the embodiments of this application is roughly as follows:
[0037] During the experiment, dust diffuses within the test chamber 1 and settles downwards through the collection funnel 2 at the top under gravity. The dust then enters the transfer box 6 via the first pipe 3 for temporary storage. The transfer box 6 has two sets of movable boxes 7 at its bottom, used to store different types of dust. When a type of dust has not reached its usage limit but a different test is needed, the corresponding movable box 7 can be controlled via the dust collection assembly 8 to store it, preventing mixed contamination.
[0038] When switching dust, the control panel 17 issues a command to start the stepper motor 84, which drives the locking gear 85 to mesh with the transverse rack 9. The sliding bracket 82 moves laterally along the inner grooved support plate 81, which drives the connecting frame 83 and the corresponding movable box 7 to switch to the bottom of the transfer box 6, thus completing the adjustment of the dust storage position. The folded corrugated pipe 12 automatically extends and retracts when the movable box 7 moves, ensuring the connection and sealing between the movable pipe 10 and the second pipe 11 to prevent dust leakage.
[0039] When a certain type of dust needs to be reused, the blower 4 starts, drawing the dust from the movable chamber 7 back to the test chamber 1 through the dust return pipe 5, thus achieving dust recycling. The electric telescopic rod 15 pushes the dust pusher 16 to reciprocate within the transfer box 6, ensuring that residual dust completely enters the movable chamber 7 and avoids cross-contamination. It should be noted that if the number of times the dust has been used in the dustproof test has reached the upper limit specified in the test standard, the test dust in the corresponding dust chamber must be replaced and cannot be reused.
[0040] The beneficial technical effects of the dustproof test chamber device for reusable dust according to the embodiments of this application are roughly as follows:
[0041] This device uses two sets of switchable movable boxes 7 to store different types of dust. When switching tests is required, the dust can be temporarily stored in one box while the other box is filled with new dust for the next test, avoiding the direct disposal of unused dust, reducing dust waste, and lowering testing costs. Through the closed-loop operation of the blower 4, dust return pipe 5, and transfer box 6, the dust after testing can be collected back into the transfer box 6 and then sorted and stored in the movable boxes 7, enabling multiple reuses of the same type of dust. On the other hand, the stepper motor 84 drives the sliding bracket 82 to move the movable box 7 laterally, enabling rapid switching between different dust boxes. A folded corrugated pipe 12 is installed at the bottom of the movable box 7 to compensate for pipe displacement during box movement and prevent dust leakage. The electric telescopic rod 15 pushes the dust pusher 16 to thoroughly clean the residual dust in the transfer box 6, ensuring no cross-contamination between different dust types. Please note that if the number of times dust is used in the dustproof test has reached the upper limit specified in the test standard, the test dust in the corresponding dust chamber must be replaced and cannot be reused.
[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
