Abstract
The utility model relates to the field of a dustproof device of a single polycrystalline vacuum pump system, in particular to a vacuum pump filter screen structure. The filter screen structure is cylindrical. The vacuum pump filter screen structure comprises a cylindrical lateral filter screen around the vacuum pump filter screen structure and an end part filter screen at the bottom. At least one layer of middle filter screen is additionally arranged inside the cylindrical lateral filter screen. Solid particles can be effectively stopped from going into pump oil by a plurality of layers of added filter screens. The cylindrical lateral filter screen is surrounded by the whole filter screen. A seam of the cylindrical lateral filter screen is connected by a detachable connecting structure. The cylindrical lateral filter screen is connected with the end part filter screen through a detachable connecting structure. The middle filter screens are connected with the cylindrical lateral filter screen by detachable connecting structures. By adopting the detachable connecting structures, when the local filter screen is broken, only the local filter screen needs to be replaced, so that the cost consumption caused by the replacement of the integral filter screen due to local damage can be effectively reduced.
Description
Technical field
The utility model relates to single polycrystalline vacuum pump system dust guard field, particularly a kind of vacuum pump filter structure.
Background technique
Existing single polycrystalline table all is equipped with filtrating equipment; The hot air flow of band particle meeting stimulating food matter is in the down last inflow pump oil in filtrating equipment top in the stove; The peripheral filter screen that covers originally of the interior shelf of existing filtrating equipment is individual layer, all-in-one-piece, as shown in Figure 1.
The model utility content
The utility model technical problem to be solved is: a kind of vacuum pump filter structure is provided, prolongs filter screen, pump oil working life.
The utility model solves the technological scheme that its technical problem adopted: a kind of vacuum pump filter structure; Filter screen is a cylindrical shape; The end filter screen of tubular side filter screen around comprising and top, bottom is set up the middle filter screen of one deck at least in filter screen inside, tubular side.The multistorey strainer mesh that adds can stop effectively that solid particle enters in the pump oil.
Tubular side filter screen is surrounded by whole filter screen, and seam crossing connects through the structure that removably connects, and connects through the structure that removably connects between tubular side filter screen and the end filter screen, is connected through the structure that removably connects between middle filter screen and the tubular side filter screen.Through the introducing structure that removably connects, when local filter screen is damaged, only need the independent replacing should the part filter screen, can effectively reduce because the cost loss that the replacing of the whole filter screen that local damage causes brings.
The structure that removably connects is a slide fastener.
The beneficial effect of the utility model is: through increasing the amount that filter screen reduces the solid particle that gets into pump oil in the unit time, prolong filter screen, the working life of pump oil and vacuum pump.Can unload separately when the Where topical filter screen has breakage, replace new a spot of filter screen and get on and just can solve, avoid filter screen to waste problem.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified;
Fig. 1 is the structural representation of existing vacuum pump filter structure;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the sectional drawing of the utility model;
Among the figure, 1. tubular side filter screen, 2. end filter screen, 3. in the middle of filter screen, 4. slide fastener.
Embodiment
Shown in Fig. 2 and 3, a kind of vacuum pump filter structure, filter screen is a cylindrical shape, the tubular side filter screen 1 around comprising and the end filter screen 2 of top, bottom, the middle filter screen 3 of one deck is at least set up in filter screen 1 inside in the tubular side.
Tubular side filter screen 1 is surrounded by whole filter screen; Seam crossing connects through the structure that removably connects; Connect through the structure that removably connects between tubular side filter screen 1 and the end filter screen 2, be connected through the structure that removably connects between middle filter screen 3 and the tubular side filter screen 1.The structure that removably connects is a slide fastener 4.Can unload separately when the Where topical filter screen has breakage, replace new a spot of filter screen and get on just to solve filter screen waste problem.
