Description

Technical Field

[0001] This invention relates to the field of electronic-grade pneumatic pump technology, specifically to an exhaust port structure for an anti-foreign-object electronic-grade pneumatic pump and its usage method. Background Technology

[0002] The exhaust port structure of the anti-foreign-object electronic-grade pneumatic pump is precisely designed. It mainly reduces noise and prevents foreign objects from entering by installing an exhaust muffler. At the same time, it is equipped with an air filter to purify the intake air and prevent contaminants from affecting the purity.

[0003] In addition, the fluid discharge valve can reduce pressure and prevent toxic fluid backflow when the pipeline is blocked, while the guide-type main air valve and fluid discharge valve further enhance the safety and stability of the system. These components together ensure the cleanliness and reliability of the electronic-grade pneumatic pump during the exhaust process, meeting the needs of high-precision industrial applications.

[0004] During the operation of an electronic-grade pneumatic pump, insufficient air cleanliness can cause diaphragm wear. Damaged diaphragms can produce impurities, which can clog the muffler and affect exhaust efficiency. Therefore, to address the above issues, a foreign object-proof electronic-grade pneumatic pump exhaust port structure and its usage method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a foreign object-proof electronic-grade pneumatic pump exhaust port structure and its usage method, in order to solve the problem that insufficient air source cleanliness during the operation of the electronic-grade pneumatic pump will cause diaphragm wear, and the damage to the diaphragm will produce impurities, which will cause the muffler to be blocked, thus affecting the exhaust efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A structure for the exhaust port of an electronic-grade pneumatic pump designed to prevent foreign objects from entering, and its usage method, includes an exhaust port located at the lower middle end of the electronic-grade pneumatic pump. An exhaust valve is installed inside the exhaust port, and a filter / silencing unit is installed outside the exhaust valve. The filter / silencing unit includes a filter housing with a filter column installed inside. A through hole is provided on the side of the filter housing. One end of the filter housing is fixedly connected to a threaded connecting tube, and a silencing column shell is fixedly connected to the outside of the filter housing via a connecting block. The exhaust valve includes a first threaded connecting tube with a connecting ring plate fixedly connected to one end. The connecting ring plate is fixedly connected to a transparent column shell via connecting screws. An annular adsorption plate is installed inside the transparent column shell, and a guide ring is installed inside the annular adsorption plate. A hexagonal block is welded and fixed to the other end of the transparent column shell, and a second threaded connecting tube is fixedly connected inside the hexagonal block. A spiral guide plate is installed inside one end of the second threaded connecting tube, and a one-way valve is installed inside the other end of the second threaded connecting tube.

[0008] As a further optimization of the present invention, the electronic-grade pneumatic pump has an air inlet at the upper middle part for connecting with an external air pump, and the electronic-grade pneumatic pump has a fixed base welded and fixed on both sides of the bottom end for supporting the entire electronic-grade pneumatic pump.

[0009] As a further optimization of the present invention, the filter shell, the silencer column shell, the filter column and the connecting internal thread column tube are on the same axis, the connecting internal thread column tube and the first external thread column tube are spirally connected, and the silencer column shell has a plurality of silencer holes equidistantly arranged in an annular shape on its outer side.

[0010] As a further optimization of the present invention, the following features are provided: multiple connecting blocks are provided, the connecting blocks are disposed between the filter shell and the sound-absorbing column shell, and a plurality of through holes are provided, the cross-section of the through holes being square.

[0011] As a further optimization of the present invention, the first externally threaded column tube, the connecting ring plate, the transparent column shell, the guide ring, the second externally threaded column tube, the annular adsorption plate, and the one-way valve are on the same axis, and the second externally threaded column tube is spirally connected to the exhaust hole.

[0012] As a further optimization of the present invention, the transparent cylindrical shell has a U-shaped cross-section, the distance between the inner wall of the transparent cylindrical shell and the annular adsorption plate is 0.5 cm, and the transparent cylindrical shell is connected to the interior of the second externally threaded cylindrical tube.

[0013] As a further optimization of the present invention, two guide rings are provided, and the two guide rings are respectively fixedly connected to the transparent cylindrical shell and the connecting ring plate, and the two guide rings are parallel to each other.

[0014] As a further optimization of the present invention, the hexagonal block has a circular hole inside, and the circular hole inside the hexagonal block is welded and fixed to the second external threaded column tube, and the included angle between the hexagonal block and the second external threaded column tube is 90°.

[0015] As a further optimization of the present invention, the annular adsorption plate has adsorption holes inside, and there are multiple adsorption holes, which are distributed in an annular and equidistant manner inside the annular adsorption plate.

[0016] As a further optimization of the present invention, the following steps are included: Step I: Exhaust valve installation: Connect the exhaust valve to the exhaust hole through the second external threaded column tube. During the connection process, use a tool that is compatible with the hexagonal prism to hold the hexagonal block, rotate the entire exhaust valve to connect, and after the connection is completed, the hexagonal block and the electronic-grade pneumatic pump are in close contact.

[0017] Step II: Installation of the filter and silencer unit: The exhaust valve and the filter and silencer unit are connected by connecting the first external threaded column tube to the connecting internal threaded column tube. After the connection is completed, the seal between the first external threaded column tube and the connecting internal threaded column tube is achieved by applying sealant or by wrapping sealing tape around the outside of the first external threaded column tube.

[0018] Step III: The exhaust valve filters the exhaust gas: When the equipment is running, the gas enters the exhaust valve through the exhaust port. When the gas enters the exhaust valve, it first passes through the one-way valve, and then through the spiral guide plate to make the exhaust gas into a cyclone. When the cyclone gas passes through the transparent column shell, if the gas contains particulate impurities, the impurities are thrown onto the annular adsorption plate under the action of centrifugal force. In this process, the guide ring has the effect of centrifuging the impurities. Finally, the gas is discharged through the first external threaded column tube.

[0019] Step IV: The filtration and silencing unit silences the exhaust valve: the gas discharged through the first external threaded column enters the filter housing, is filtered by the filter column, and is discharged through the through hole. The discharged gas is silenced by the silencing column housing and then discharged to the outside.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, by setting an exhaust valve, when the air source is not clean and the internal diaphragm of the electronic-grade pneumatic pump is damaged, the impurities in the air source and the impurities generated by the wear of the diaphragm can be collected, thereby preventing the impurities from entering the filter and silencer unit, ensuring exhaust efficiency, and ensuring the operation of the electronic-grade pneumatic pump.

[0022] 2. In this invention, by using the transparent cylindrical shell and the annular adsorption plate, the cyclone generated by the spiral guide plate and the centrifugal force are used to collect the impurities generated during the exhaust process. At the same time, the collected impurities can be observed to determine the damage to the diaphragm of the electronic-grade pneumatic pump.

[0023] 3. In this invention, the noise generated by the exhaust can be further eliminated by the filter and silencing unit, thereby improving the working environment around the electronic pneumatic pump. At the same time, in practical applications, the filter shell can simply adsorb impurities and water vapor to ensure the stability of the overall operation of the device. Attached Figure Description

[0047] Step III: The exhaust valve 5 filters the exhaust gas: When the equipment is running, the gas enters the exhaust valve 5 through the exhaust port 6. When the gas enters the exhaust valve 5, it first passes through the one-way valve 510, and then passes through the spiral guide plate 59 to make the discharged gas cyclone. When the cyclone gas passes through the transparent column shell 54, if the gas contains particulate impurities, the impurities are thrown onto the annular adsorption plate 58 under the action of centrifugal force. During this process, the guide ring 55 has the function of centrifuging the impurities. Finally, the gas is discharged through the first external threaded column tube 51.

[0048] Step IV: The filter and silencer unit 4 silences the exhaust valve 5: the gas discharged through the first external threaded column tube 51 enters the filter shell 41, and after being filtered by the filter column 45, it is discharged through the through hole 44.
