Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dustproof test chambers, specifically a dustproof test chamber structure. Background Technology
[0002] Dustproof test chambers are devices used to simulate climatic environments. This equipment helps evaluate the ability of equipment to withstand the effects of dust that can clog openings, seep into cracks, gaps, bearings, and joints, and to maintain performance, efficiency, reliability, and maintainability without being affected by the abrasive or clogging effects of large, sharp-edged sand particles. It is used to evaluate all mechanical, optical, electrical, electronic, electromechanical, and electrochemical devices that may be exposed to dry sandblasting, dusty atmospheres, or dustfall conditions.
[0003] When using existing dustproof test chambers, the dust blown out of the dust outlet pipe tends to concentrate and blow towards the top of the inner chamber, resulting in poor dust diffusion. This affects the dust's ability to fall onto the tested equipment and thus the test results. In addition, when using existing test chambers, the dust suction pipe in the dust collection hopper faces upwards, and dust easily clogs the suction port under gravity, affecting the dust blowing effect. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a dustproof test chamber structure. By setting dust dispersion balls, the dust blown out of the dust outlet pipe will be evenly dispersed and fall when it encounters the dust dispersion balls, so that the dust will fall evenly on the test items, ensuring the test effect and effectively solving the problems in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof test chamber structure, including an outer box, an inner box inside the outer box, a dust-scattering ball on the top side of the inner box, a dust outlet pipe on the inner side of the inner box, the air outlet of the dust outlet pipe aligned with the dust-scattering ball, a dust collection hopper at the bottom of the inner box, a suction pipe extending horizontally through the bottom side of the dust collection hopper, suction ports evenly spaced on the lower side of the suction pipe, and a vibration motor installed on the lower side of the dust collection hopper.
[0006] Furthermore, a door is provided on one side of the outer casing, and a clamping nut is provided on one side of the door, with a threaded rod passing through the center of the clamping nut.
[0007] Furthermore, an operation panel is provided on the side of the outer casing where the door is located, and a vacuum fan is connected to the vacuum pipe.
[0008] Furthermore, a dust supply pipe is connected to the exhaust pipe of the dust extraction fan, and the dust supply pipe is connected to the exhaust pipe via a flange.
[0009] Furthermore, the lower side of the inner box is connected to the outer box via a support frame, and the dust suction pipe is welded to the dust collection hopper.
[0010] Furthermore, the dust outlet pipe is inclined upward at 45 degrees, and the threaded rod is hinged to the outer casing.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the setting of a retaining ring and a rubber ring, allows the retaining ring to be flexibly connected to the retaining ring groove after it is inserted into the retaining ring groove, thereby avoiding friction damage between the retaining ring and the retaining ring groove and ensuring the retaining effect of the retaining ring in the retaining ring groove.
[0013] 2. This utility model, through the setting of a suction pipe, a vibration motor, and a downward-facing suction port, allows the suction port of the suction pipe to be positioned downwards on the bottom side of the dust collection hopper. The vibration motor can vibrate the dust collection hopper, causing the dust inside to be dispersed, thereby allowing the suction port on the lower side of the suction pipe to suck away the dust and preventing dust from clogging the suction port.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3This embodiment provides a technical solution: a dustproof test chamber structure, including an outer box 1, an inner box 6 is provided inside the outer box 1, a dust ball 14 is provided on the top side of the inner box 6, a dust outlet pipe 7 is provided on the inner side of the inner box 6, the air outlet of the dust outlet pipe 7 is aligned with the position of the dust ball 14, a dust collection hopper 9 is provided at the bottom of the inner box 6, a suction pipe 8 is horizontally inserted through the bottom side of the dust collection hopper 9, suction ports 12 are provided at equal intervals on the lower side of the suction pipe 8, and a vibration motor 13 is installed on the lower side of the dust collection hopper 9.
[0020] like Figure 1-3 As shown, during the dustproof test, loosen the clamping nut 4, then rotate the threaded rod 5 off the door 2 to open the door 2, and then place the test equipment into the inner chamber 6 through the test rack. Then close the door 2 and start the equipment through the control panel 3. The dust collector 10 sucks in the test dust collected inside the dust collection hopper 9 through the dust collection pipe 8 and sends it into the dust outlet pipe 7 through the dust delivery pipe 11. The dust outlet pipe 7 blows the dust onto the dust ball 14, so that the dust is evenly diffused and falls, and thus the dust can fall evenly onto the upper side of the equipment to ensure the test effect. The vibration motor 13 can drive the dust collection hopper 9 to vibrate, so that the dust inside the dust collection hopper 9 can be quickly sucked away by the dust suction port 12 on the dust collection pipe 8 to ensure the dust collection effect of the dust collector 10.
[0021] A door 2 is provided on one side of the outer casing 1, and a clamping nut 4 is provided on one side of the door 2. A threaded rod 5 is passed through the center of the clamping nut 4.
[0022] The outer casing 1 has a door 2 and an operation panel 3 on its side. A vacuum cleaner 10 is connected to the vacuum pipe 8.
[0023] The dust extraction fan 10 has a dust delivery pipe 11 connected to its outlet pipe, and the dust delivery pipe 11 is connected to the dust outlet pipe 7 via a flange.
[0024] The lower side of the inner box 6 is connected to the outer box 1 by a support frame, and the dust suction pipe 8 is welded to the dust collection hopper 9.
[0025] The dust outlet pipe 7 is tilted upward at 45 degrees, and the threaded rod 5 is hinged to the outer casing 1.

Then close the door 2 and start the equipment through the control panel 3. The dust collector 10 sucks in the test dust collected inside the dust collection hopper 9 through the dust collection pipe 8 and sends it into the dust outlet pipe 7 through the dust delivery pipe 11. The dust outlet pipe 7 blows the dust onto the dust ball 14, so that the dust is evenly diffused and falls, and thus the dust can fall evenly onto the upper side of the equipment to ensure the test effect. The vibration motor 13 can drive the dust collection hopper 9 to vibrate, so that the dust inside the dust collection hopper 9 can be quickly sucked away by the dust suction port 12 on the dust collection pipe 8 to ensure the dust collection effect of the dust collector 10.
