Detailed Description

The present invention will be described in detail with reference to fig. 1 to 3.

The utility model relates to a disassembly-free self-cleaning vacuum pump filter. The device comprises a shell 1, a filter screen 2 and a cleaning device 3, wherein the filter screen 2 is arranged in the shell 1, the shell 1 is cylindrical, an air inlet 11 used for being connected with a workshop is formed in the top of the shell 1, a mounting hole 12 is formed in one side of the air inlet 11, an air outlet 13 used for being connected with a vacuum pump is formed in one side of the shell 1, and a first clamping groove 14 and a second clamping groove 15 are formed in the shell 1; the filter screen 2 is fixedly connected with the first clamping groove 14 and the second clamping groove 15; the cleaning device 3 comprises a shower head 31 and a sewage discharge pipe 32, the shower head 31 is arranged in the filter screen 2, the shower head 31 is connected with a water inlet pipe 33, one end of the water inlet pipe 33 is connected with one end of the shower head 31, penetrates through the mounting hole 12 and extends outwards to form the shell 1, and the sewage discharge pipe 32 is arranged at the bottom of the shell 1 and is communicated with the shell 1. One end of the device is connected with a workshop production end, the other end of the device is connected with a vacuum pump, when the vacuum pumping is needed, gas enters the filter from the gas inlet 11 at the top, passes through the filter screen 2 and then is discharged from the gas outlet 13 at the side. The impurities in the gas are blocked in the filter screen and all stay in the filter screen. The process can effectively prevent the occurrence of abnormal conditions such as dead jamming and collision of the machine head due to the fact that foreign matters enter the vacuum pump. After a period of use, the switch of the inlet pipe 33 and the drain pipe 32 is turned on in case the vacuum pump is turned off. Clear water enters from the water inlet, and through the reposition of redundant personnel of gondola water faucet 31, even spraying is everywhere to the filter screen, and the impurity dirt of filter screen inner wall is along the filter screen down-flow, discharges from blow off pipe 32 of below. After cleaning, the two valves are turned off, the vacuum pump can normally operate without disassembling and manually cleaning the filter, so that the various problems are overcome, and the production cost is reduced.

In the utility model, in order to further prevent the foam particles from blocking the vacuum pump, the filter screen 2 has a three-layer structure, a first layer of filter screen, a second layer of filter screen and a third layer of filter screen are sequentially arranged at intervals from inside to outside, and the pore diameters of the three layers of filter screens are sequentially reduced. The design of three-layer filter screen can not only prevent that the foam granule from blockking up the vacuum pump, can also block up the filtration pore when influencing the evacuation effect at the foam granule, takes out the filter screen fast and changes or clear up, alright resume production, need not to install the filter screen again.

Meanwhile, the three layers of filter screens are uniformly distributed with filter holes 21 for filtering gas, and after the gas passes through the filter screens, foreign matters are blocked on the filter screens, so that the gas purifying effect is achieved.

Similarly, the end of the water inlet pipe 33 extending out of the shell 1 and the sewage discharge pipe 32 are both provided with a first water stop valve 4 and a second water stop valve 5, and the purpose of the water stop valves is to enable the vacuum pump to be used normally.

In the technical scheme, the air inlet 11 and the air outlet 13 are used for installing the vacuum pump filter between a workshop production end and a vacuum pump through the sealing flange 6.

In the present invention, a gap is left between the housing 1 and the filter screen 2. When needs wash the filter screen, first stagnant water valve 4 is opened, and the reposition of redundant personnel that the gondola water faucet 31 was flowed through to the rivers washs filter screen 2, leaves the space between shell 1 and the filter screen 2, can prevent effectively that sewage from flowing into the vacuum pump through gas outlet 13 in, harm the vacuum pump.

Further, in the cleaning process, the shower head 31 is used for dividing water to achieve the purpose of cleaning the filter screen comprehensively, so that the shape of the shower head 31 is generally set to be spherical, cylindrical or square. The shape of the shower head 31 can be changed correspondingly according to actual conditions, and is not limited.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
