Description

Technical Field

[0001] This utility model relates to the technical field of sand and dust test chambers, specifically an anti-clogging sand and dust test chamber. Background Technology

[0002] A dust test chamber is a testing device that simulates a natural dust environment. By controlling parameters such as dust concentration and wind speed, it evaluates the dustproof performance and durability of products (such as automotive parts and electronic equipment). It is widely used in the automotive and electronics industries to ensure product reliability in dusty environments.

[0003] Existing dust test chambers simulate dust by using airflow through the inlet and outlet. However, a significant problem with these chambers is that dust easily gets clogged at the inlet, outlet, and internal circulation channels. This clog not only affects the normal flow and uniform distribution of dust, leading to inaccurate test results, but can also damage the chamber's power system, such as the fan, increasing maintenance costs and downtime, and reducing test efficiency. Therefore, optimization and improvement are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-clogging dust test chamber to solve the problem mentioned in the background art that dust can easily cause blockage of the air inlet and outlet during dust tests, affecting the experimental results and reducing the service life of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging sand and dust test chamber, comprising: a sand and dust test chamber body, a sealing door panel connected to the front end of the sand and dust test chamber body, a control panel fixedly installed on one side of the front wall of the sand and dust test chamber body, and further comprising a ventilation anti-clogging component and an air intake anti-clogging component:

[0006] The ventilation anti-clogging component is installed inside the top wall of the sand and dust test chamber. The ventilation anti-clogging component includes a filter pipe, an inner filter plate connected to the inner side of the filter pipe, and a filter baffle fixedly connected to the bottom end of the filter pipe. The ventilation anti-clogging component is used to prevent clogging at the ventilation point during sand and dust tests. The air intake anti-clogging component is installed inside the sand and dust test chamber. The air intake anti-clogging component includes a collection hopper, an inclined pipe fixedly connected to one side of the collection hopper, and a connecting pipe provided at the top end of the inclined pipe. The air intake anti-clogging component is used to prevent clogging at the air intake point during sand and dust tests.

[0007] Preferably, a sealing partition is fixedly connected to the middle of the inner side of the dust test chamber, and a mounting frame is fixedly connected to the top of the sealing partition.

[0008] Preferably, a blower is fixedly connected to one end of the outer side of the dust test chamber, and the inclined pipe is fixedly connected to the inner side of the blower.

[0009] Preferably, a blower two is fixedly installed on one side of the top of the dust test chamber, and the connecting pipe is fixedly connected to one end of the blower two.

[0010] Preferably, the filter pipe is connected to the inside of the top wall of the sand and dust test chamber, a sealing gasket is connected to the bottom of the outer side of the filter pipe, and a fastening ring is threaded to the top of the outer side of the filter pipe.

[0011] Preferably, an inner filter plate is connected to the inner side of the filter pipe, and a handle is fixedly connected to the top of the inner filter plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention facilitates air circulation inside and outside the testing equipment by setting an air outlet on the inner side of the sand and dust test chamber. By controlling the wind force to stir up sand and dust, a sand and dust test is simulated. During the sand and dust diffusion process, the air outlet is prevented from being blocked. A filter baffle and an inner filter plate are set to filter and adjust the outlet. The filter baffle and inner filter plate are also easy to remove, avoiding long-term blockage that affects the test results and ensuring the service life of the equipment.

[0016] During air intake, the upward-sloping pipe blows air into the collection hopper. The sloping design prevents the sand from clogging the end of the pipe due to gravity. The connecting pipe at the top is also sloping, which can limit the direction of flow and prevent sand and dust from accumulating at the air intake and causing blockage, thus improving the efficiency of the test chamber.

[0025] Specifically, such as Figure 2 As shown, a sealing partition 4 is fixedly connected to the middle of the inner side of the dust test chamber 1, and a mounting frame 5 is fixedly connected to the top of the sealing partition 4. The mounting frame 5 is used to place the products for the dust test.

[0026] The ventilation anti-clogging component is installed inside the top wall of the sand and dust test chamber 1. The ventilation anti-clogging component includes a filter pipe 11, an inner filter plate 16 is connected to the inner side of the filter pipe 11, and a filter baffle 12 is fixedly connected to the bottom end of the filter pipe 11. The ventilation anti-clogging component is used to prevent clogging at the ventilation point during the sand and dust test.

[0027] Specifically, such as Figure 3 As shown, the filter pipe 11 is connected to the inside of the top wall of the sand and dust test chamber 1. A sealing gasket 14 is connected to the bottom of the outer side of the filter pipe 11. The sealing gasket 14 is attached to the top inner wall of the sand and dust test chamber 1 to achieve the effect of protection and sealing. A fastening ring 15 is threaded to the top of the outer side of the filter pipe 11. The fastening ring 15 is connected to the outer side of the filter pipe 11 and is used to fix the filter pipe 11.

[0028] Specifically, such as Figure 3 As shown, an inner filter plate 16 is connected to the inner side of the filter pipe 11, and a handle 17 is fixedly connected to the top of the inner filter plate 16. The inner filter plate 16 performs secondary filtration on the filter pipe 11, and the handle 17 facilitates the movement of the inner filter plate 16.

[0029] Specifically, such as Figure 3 As shown, the inner side of the filter pipe 11 is provided with a docking groove 13 that is slidably connected to the inner filter plate 16. The inner filter plate 16 slides inside the docking groove 13 and then rotates to engage.

[0030] The air intake anti-blocking component is located inside the sand and dust test chamber 1. The air intake anti-blocking component includes a collection hopper 6, a slanted pipe 8 is fixedly connected to one side of the collection hopper 6, and a connecting pipe 10 is provided at the top of the slanted pipe 8. The air intake anti-blocking component is used to prevent blockage at the air intake during the sand and dust test.

[0031] Specifically, such as Figure 1 As shown, a blower 7 is fixedly connected to one end of the outer side of the dust test chamber 1, and an inclined pipe 8 is fixedly connected to the inner side of the blower 7. The inclined pipe 8 is inclinedly connected to the bottom of the collection hopper 6 to facilitate the agitation of dust.

[0032] Specifically, such as Figure 1 As shown, a blower 2 9 is fixedly installed on one side of the top of the dust test chamber 1. A connecting pipe 10 is fixedly connected to one end of the blower 2 9. Two branch pipes are provided at the contact position between the connecting pipe 10 and the top wall of the dust test chamber 1. The pipes are in an inclined state.

[0033] Specifically, such as Figure 4 As shown, the collecting hopper 6 is fixedly connected to the bottom of the sealing partition 4. The inner bottom of the collecting hopper 6 is connected to a rotating block 18, and the top of the rotating block 18 is connected to a plug 19. The rotating block 18 drives the plug 19 to seal the bottom of the collecting hopper 6, which facilitates the collection of sand and dust.

[0034] In this embodiment: an air outlet is provided inside the sand and dust test chamber 1 to allow air circulation inside and outside the test equipment. By controlling the wind force to stir the sand and dust, a sand and dust test is simulated. During the sand and dust diffusion process, to avoid the air outlet from being blocked, a filter baffle 12 and an inner filter plate 16 are set to filter and adjust the outlet. The filter baffle 12 and the inner filter plate 16 are also easy to remove. When the air is inlet, the collection hopper 6 is blown by the inclined pipe 8 set upward. The inclined setting will not cause the end of the inclined pipe 8 to be blocked due to the gravity of the sand and soil. The connecting pipe 10 set at the top is also inclined, which can limit the direction of flow to a certain extent and prevent sand and dust from accumulating at the air inlet and causing blockage.

[0035] Specifically, this solution involves installing an inclined pipe 8 and a filter pipe 11 inside the dust test chamber 1 for air intake. The filter pipe 11 then exits through the top wall of the dust test chamber 1, increasing airflow between the inside and outside of the chamber and facilitating the adjustment of internal dust agitation. Different levels of dust test simulation are achieved by controlling the wind speed of blower 7 and blower 9. The upwardly inclined pipe 8 blows air into the collection hopper 6. The inclined design prevents blockage at the end of the pipe 8 due to the weight of the sand. The connecting pipe 10 at the top is also inclined. The placement of the filter baffle 12 and inner filter plate 16 can restrict the direction of airflow to a certain extent, preventing the outlet from becoming blocked during sandstorms. The filter baffle 12 and inner filter plate 16 are set up to filter and adjust the outlet, avoiding environmental impact. After long-term use, if the inner side of the filter baffle 12 and inner filter plate 16 becomes blocked, the inner filter plate 16 can be rotated to pull it out of the filter pipe 11 for cleaning. The filter baffle 12 can be removed by rotating the fastening ring 15 and then moving the filter pipe 11 down, which facilitates the removal and cleaning of the filter baffle 12. This greatly reduces the blockage of the inner pipe of the sandstorm test chamber 1 during sandstorm tests and improves the service life of the equipment.
