Description

Technical Field

[0001] The utility model relates to the technical field of sampling pump anti-blocking, in particular to a sampling pump anti-blocking device. Background Technique

[0002] A sampling pump is a pump product used for sampling and collecting gases or liquids. The sampling pump is mainly used for sampling and collecting gases or liquids. Thus, it can be divided into a gas sampling pump and a liquid sampling pump according to the working medium.

[0003] Research shows that the existing sampling pumps still have the following defects:

[0004] When the existing sampling pump collects gas, due to the lack of a filtering device, dust enters the collection pump and causes the collection pump to be blocked. Although setting a filter screen can prevent dust from entering the interior of the collection pump, after the filter screen is used for a period of time, dust will adhere to it, thereby causing the filter screen to be blocked. Therefore, through technological innovation and design optimization, it is necessary to optimize the sampling pump anti-blocking device. Summary of the Utility Model

[0005] When the existing sampling pump collects gas, due to the lack of a filtering device, dust enters the collection pump and causes the collection pump to be blocked. Although setting a filter screen can prevent dust from entering the interior of the collection pump, after the filter screen is used for a period of time, dust will adhere to it, thereby causing the filter screen to be blocked. To solve the above problems, the embodiment of the present application provides a sampling pump anti-blocking device. By setting a filter screen, the blockage of the sampling pump body can be avoided. At the same time, through a moving mechanism, a brush plate can be driven to clean the filter screen to avoid the blockage of the filter screen. By setting a moving block and a through hole, the dust inside the cleaning cavity can be quickly discharged to avoid dust accumulation inside the cleaning cavity.

[0006] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0007] A sampling pump anti-blocking device, comprising:

[0008] A sampling pump body, on one side of which a rectangular block is fixed. An air inlet hole and an exhaust hole are opened on the rectangular block. A cleaning cavity is opened inside the rectangular block. The cleaning cavity is communicated with the air inlet hole. A filter screen is fixed at the position of the exhaust hole corresponding to the cleaning cavity. A brush plate is arranged inside the cleaning cavity. A moving mechanism capable of driving the brush plate to move is arranged on the top of the rectangular block. A dust discharging mechanism capable of discharging dust is also arranged at the bottom inside the cleaning cavity.

[0009] In a possible implementation, the moving mechanism includes a U-shaped plate fixed to the top of a rectangular block. A guiding column passes through the U-shaped plate. The bottom end of the guiding column passes through the rectangular block and is fixedly connected to a brush plate. Pushing the guiding column downward, the guiding column drives the brush plate to clean the dust on the filter screen. The dust swept down will fall onto the moving block, preventing the dust from adhering to the filter screen and causing blockage of the filter screen.

[0010] In a possible implementation, a pressing plate is fixed to the top of the guiding column. A spring is sleeved between the U-shaped plate and the rectangular block on the outer part of the guiding column. A baffle is fixed between the spring and the U-shaped plate on the outer part of the guiding column. When the guiding column drives the baffle to move downward, the spring will be compressed. After releasing the hand, under the action of the spring, the guiding column will drive the brush plate to automatically reset, without the need for the staff to lift the guiding column upward.

[0011] In a possible implementation, the dust discharging mechanism includes a through hole opened at the bottom of the rectangular block. The through hole is communicated with the cleaning cavity. A moving block is arranged inside the cleaning cavity. The moving block can move inside the cleaning cavity. One end of the moving block passes through the rectangular block and is fixed with a fixed block. By pulling the moving block through the fixed block, the dust on the moving block is pushed down and falls through the through hole, thereby completing the rapid cleaning of the dust.

[0012] In a possible implementation, sliding grooves two are opened on both sides of the inner wall of the cleaning cavity. Sliding blocks two are arranged inside the sliding grooves two. The sliding blocks two are fixedly connected to the moving block. The moving block will drive the sliding blocks two to slide inside the sliding grooves two, preventing the moving block from falling off and ensuring the stability of the moving block during movement at the same time.

[0013] In a possible implementation, a fixing plate is fixed to the outside of the rectangular block. A limiting plate is arranged on the side of the fixing plate away from the rectangular block. A sliding groove one is opened on the fixing plate. A sliding block one is arranged inside the sliding groove one. The sliding block one is fixedly connected to the limiting plate. Due to the action of gravity, the limiting plate will drive the sliding block one to slide inside the sliding groove one. The limiting plate will block the moving block to prevent the moving block from moving inside the cleaning cavity.

[0014] In a possible implementation, a limiting groove is opened at the bottom end of the limiting plate. The limiting groove can accommodate the fixed block, which is convenient for blocking the moving block.

[0015] In a possible implementation, the bristles on the brush plate face the side of the filter screen, which is convenient for cleaning the filter screen.

[0016] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0017] 1. By pushing the guide post downward, the guide post drives the brush plate to clean the dust on the filter screen. The dust swept down will fall onto the moving block, preventing the dust from adhering to the filter screen and causing blockage. When the guide post drives the baffle to move downward, the spring will be compressed. After releasing the hand, under the action of the spring, the guide post will drive the brush plate to automatically reset, without the need for the staff to lift the guide post upward;

[0018] 2. By pulling the moving block through the fixed block, the dust on the moving block is pushed down and falls through the through hole, thereby completing the rapid cleaning of the dust. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] When the air intake volume of the filter screen 17 becomes small, the moving mechanism includes a U-shaped plate 4 fixed on the top of the rectangular block 3. A guiding column 11 penetrates through the U-shaped plate 4. The bottom end of the guiding column 11 penetrates through the rectangular block 3 and is fixedly connected to the brush plate 12. By pushing the guiding column 11 downward, the guiding column 11 drives the brush plate 12 to clean the dust on the filter screen 17. The cleaned dust will fall onto the moving block 14, preventing the dust from adhering to the filter screen 17 and causing blockage of the filter screen 17.

[0029] In addition, a pressing plate 5 is fixed on the top of the guiding column 11. A spring 18 is sleeved between the U-shaped plate 4 and the rectangular block 3 on the outside of the guiding column 11. A baffle 19 is fixed between the spring 18 and the U-shaped plate 4 on the outside of the guiding column 11. When the guiding column 11 drives the baffle 19 to move downward, the spring 18 will be compressed. After letting go, under the action of the spring 18, the guiding column 11 will drive the brush plate 12 to automatically reset, without the need for the staff to pull the guiding column 11 upward.

[0030] When it is necessary to clean the dust in the cleaning chamber 16, the dust discharging mechanism includes a through hole 15 opened at the bottom of the rectangular block 3.

The limiting plate 8 will block the moving block 14 to prevent the moving block 14 from moving inside the cleaning chamber 16.

[0033] Meanwhile, a limiting groove 22 is formed at the bottom end of the limiting plate 8. The limiting groove 22 can accommodate the fixing block 9, which is convenient for blocking the moving block 14.

[0034] When the brush plate 12 moves, the bristles on the brush plate 12 face the side of the filter screen 17, which is convenient for cleaning the filter screen 17.

[0035] The model of the sampling pump body 6 is a CEMS gas sampling pump.

[0036] When the staff needs to clean the filter screen 17, push the guide post 11 downward. The guide post 11 drives the brush plate 12 to clean the dust on the filter screen 17. The cleaned dust will fall on the moving block 14, avoiding the dust adhering to the filter screen 17 and causing blockage to the filter screen 17. When the guide post 11 drives the baffle 19 to move downward, the spring 18 will be compressed. After releasing the hand, under the action of the spring 18, the guide post 11 will drive the brush plate 12 to automatically reset, without the staff having to lift the guide post 11 upward. When it is necessary to clean the dust inside the cleaning cavity 16 after a period of time, pull the moving block 14 through the fixing block 9, so that the dust on the moving block 14 is pushed off and falls from the through hole 15, thereby completing the rapid cleaning of the dust.
