Abstract

The utility model discloses an air inlet filter device for a vacuum pump. The air inlet filter device comprises an air inlet pipe, a first nipple, a first female flange, a filter pipe, a filter bead, a second female flange, a second nipple, an air outlet pipe and sealing gaskets. The first female flange and the second female flange are embedded in the two ends of the filter pipe respectively, wherein the diameter of the concave surface of the first female flange and the diameter of the concave surface of the second female flange are matched with the diameter of the filter pipe. The sealing gaskets are arranged between the filter pipe and the first flange and between the filter pipe and the second flange respectively. The filter bead is further arranged in the filter pipe. The first nipple is welded at the other end of the first female flange. The second nipple is welded at the other end of the second female flange. The first nipple and the second nipple are connected with the air inlet pipe and the air outlet pipe respectively. The filter device is arranged on the air inlet, therefore, the filter effect can be greatly improved, impurities and the like can be left in the filter pipe, then the vacuum pump can not be polluted, the service life is prolonged, efficiency is improved, and the air inlet filter device is simple in structure, low in cost and easy to clean and replace.

Description

A kind of vacuum pump air intake filter
Technical field
The utility model relates to a kind of filtrating equipment of air-inlet of vacuum pump.
Background technique
Current TPEE(thermoplastic polyester elastomer) while synthesizing polycondensation reaction, need micro-vacuum, in operating process, be all at vacuum pump suction tude place, filter screen to be set to filter, but the filtering effect of filter screen does not all reach good effect, in gas, unfiltered moisture, impurity etc. are easy to vacuum pump is polluted and affect working efficiency, if pumping fluid is polluted, so just reduce greatly the power of vacuum pump.
The model utility content
In order to overcome the problems referred to above, the utility model proposes a kind of vacuum pump air intake filter, in the past simple filter screen replaced to the better filtrating equipment of filtering effect, solved filtering effect in the prior art bad and affect the problem of vacuum pump power.
The technical solution of the utility model specifically is achieved through the following technical solutions:
A kind of vacuum pump air intake filter, comprise suction tude, the first nipple, the first female flange, screen pipe, filtration pearl, the second female flange, the second nipple, steam outlet pipe and sealing gasket, the two ends of described screen pipe are embedded with respectively the first female flange and the second female flange that concave surface diameter and described screen pipe diameter match, between described screen pipe and described the first flange, described screen pipe and described the second flange, be respectively equipped with sealing gasket, in the pipe of described screen pipe, also be provided with the filtration pearl; The other end welding first nipple of described the first female flange, the other end welding second nipple of described the second female flange; Described the first nipple, the second nipple connect respectively suction tude, steam outlet pipe;
Preferably, between the first nipple and suction tude, between the second nipple and steam outlet pipe for being threaded;
Preferably, the diameter of described filtration pearl is greater than respectively the internal diameter of described the first female flange, the second female flange;
Preferably, described filtration pearl is glass bead;
Preferably, described screen pipe is withstand voltage glass tube with vacuum.
The beneficial effect that the utility model produces is: by filtrating equipment of the present utility model is set at suction port, in air inlet, can promote greatly filtering effect during by filtrating equipment, impurity etc. is stayed in screen pipe, thereby can not pollute vacuum pump, life-saving is raised the efficiency, the utility model is simple in structure simultaneously, cost is low, and easily cleaned and changed.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment who obtains, and all belong to the scope of the utility model protection.
Be illustrated in figure 1 a preferred embodiment structural representation of the present utility model, comprise suction tude 5, the first nipple 7, the first female flange 1, screen pipe 3, filter pearl 4, the second female flange 2, the second nipple 8, steam outlet pipe 6 and sealing gasket (not indicating in figure), the two ends of screen pipe 3 are embedded with respectively the first female flange 1 and the second female flange 2, the first above-mentioned female flange 1 and the concave surface diameter of the second female flange 2 and described screen pipe 3 diameters match, described screen pipe 3 and described the first flange 1, between described screen pipe 3 and described the second flange 2, be respectively equipped with sealing gasket.Above-mentionedly installation is set can guarantees between the first female flange 1, the second female flange 2 and screen pipe 3 that sealing is and airtight, gas can not be leaked to beyond screen pipe 3.
As preferred embodiment, in the pipe of above-mentioned screen pipe 3, be provided with and filter pearl 4, wherein the pearl that filters 4 can be the pearl of glass bead or other filtering functions, screen pipe 4 is withstand voltage glass tube with vacuum; The other end welding first nipple 7 of described the first female flange 1, the other end welding second nipple 8 of described the second female flange 2; Described the first nipple 7, the second nipple 8 connect respectively suction tude 5, steam outlet pipe 6; Between the first nipple 7 and suction tude 5, between the second nipple 8 and steam outlet pipe 6 for being threaded.Dismountable being threaded or other Placements, when the filtration pearl 4 filtering effect variation of screen pipe inside or maintenance, only need to unclamp the first female flange 1, the second female flange 2 and screen pipe 3 and just can change or clean.Due to fully airtight between screen pipe 3 and the first female flange 1, the second female flange 2, gas just can, fully by filtering pearl 4 by screen pipe 3 time, reach great filtering effect like this.
Preferably, the diameter of described filtration pearl 4 is greater than respectively the internal diameter of described the first female flange 1, the second female flange 2, filtering effect can further be improved fully by gas contact filtration pearl 4 in the suction port and the air outlet that are filtrating equipment, promotes filtering effect.
When the filtration pearl 4 filtering effect variation in screen pipe 3 or other failure problems need to be dismantled, can be by dismantling between a nipple 7 and suction tude 5, change filtrating equipment between the second nipple 8 and steam outlet pipe 6, perhaps dismantle screen pipe 3 and change filtration pearl 4 etc., very convenient and practical.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
