Description

Technical Field

[0001] The utility model specifically relates to a low vacuum pressurized exhaust system device. Background Art

[0002] Vacuum system. It is a complete vacuum system consisting of vacuum pump, PLC program control system, gas storage tank, vacuum pipeline, vacuum valve, external filter assembly, etc. At present, this system is widely used in electronic semiconductor industry, optoelectronic backlight module, mechanical processing and other industries. After the vacuum system is completed, it needs to be exhausted through the exhaust device to reduce the pressure.

[0003] When the exhaust device of the existing vacuum system is exhausting, a large amount of liquefied gas is usually discharged. The discharged liquefied gas may contain some impurities. In order to ensure its environmental protection, a filter component is generally installed at the tail of the exhaust device of the vacuum system. However, the installed filter component will filter the liquid and other impurities in the liquefied gas at one time. This filtering method has low filtering efficiency and poor effect. Moreover, when the filter component is installed in the exhaust device of the vacuum system, it may be difficult to disassemble, so it is not convenient for maintenance. Utility Model Content

[0004] The purpose of the utility model is to provide a low vacuum boosting exhaust system device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a low vacuum booster exhaust system device, comprising a valve body, an air inlet pipe and an air outlet pipe arranged on the valve body, a deliquidator being installed on the air outlet pipe, a gas buffer tube being installed at the outlet end of the deliquidator, and a gas filter being embedded in the outlet end of the gas buffer tube.

[0006] A gas uniform distribution plate is arranged at the gas inlet of the deliquidator.

[0007] The gas buffer tube is an inverted U-shaped tube.

[0008] The gas filter is installed at the outlet of the gas buffer tube in a threaded or magnet-adsorbed manner.

[0009] A grabbing portion is arranged on the outer side of the gas outlet end of the gas filter.

[0010] The air inlet of the gas filter is trumpet-shaped.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: a deliquidator, a gas buffer tube and a gas filter are sequentially installed on the gas outlet pipe of the utility model, which can separate and remove the liquid and other impurities in the liquefied gas, thereby improving the filtering efficiency and effect, and the gas buffer tube can reduce the flow rate of the gas, making the subsequent filtering more sufficient; the deliquidator, the gas buffer tube and the gas filter are respectively detachably installed on the gas outlet pipe, which is convenient for disassembly and therefore convenient for maintenance and repair.

[0012] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. In the accompanying drawings:

[0013] Figure 1 It is a structural schematic diagram of the utility model;

[0014] In the figure: 1 valve body; 2 air inlet pipe; 3 air outlet pipe; 4 deliquidator; 5 gas buffer pipe; 6 gas filter; 7 gas uniform distribution plate; 8 grabbing part. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example 1

[0017] See also Figure 1 The utility model provides a technical solution: a low vacuum boost exhaust system device, including a valve body 1, an air inlet pipe 2 and an air outlet pipe 3 arranged on the valve body 1, a deliquidator 4 is installed on the air outlet pipe 3, a gas buffer tube 5 is installed at the outlet end of the deliquidator 4, and a gas filter 6 is embedded in the outlet end of the gas buffer tube 5.

[0018] A gas distribution plate 7 is provided at the gas inlet of the deliquidator 4 .

[0019] The gas buffer tube 5 is an inverted U-shaped tube, which slows down the flow rate of the gas, making the subsequent filtering more complete.

[0020] The gas filter 6 is installed at the outlet of the gas buffer tube 5 in a threaded manner or a magnet adsorption manner.

[0021] Example 2

[0022] On the basis of the technical solution of Example 1, a gripping portion 8 is provided on the outer side of the gas outlet end of the gas filter 6 to facilitate the disassembly and installation of the gas filter 6 .

[0023] The air inlet of the gas filter 6 is trumpet-shaped, which facilitates the gas to flow into the gas filter 6.

[0024] The working principle of the utility model is as follows: the liquefied gas enters the deliquidator 4 from the gas outlet pipe 3. After the deliquidator 4 removes the liquid, the gas flows into the gas filter 6 after being decelerated by the gas buffer tube 5. Other impurities are removed under the filtration of the gas filter 6. The liquid and other impurities in the liquefied gas can be removed separately, thereby improving the filtration efficiency and effect. The deliquidator 4 and the gas filter 6 are common devices in the market. Their specific structure and model can be determined according to the properties of the liquid and impurities in the liquefied gas, and there is no need to describe them in detail in this copy!
