The utility model purpose is: overcome the deficiency of prior art, a kind of liquid filter that operating efficiency can be cleaned filter core again automatically of can guaranteeing to filter is provided.
The utility model is achieved in that the liquid filter of automatic cleaning filter core, has vertically disposed filter core cylinder and be used for cleaning automatically the pressure reduction suckion remover of filter core in casing, it is characterized in that:
(1) the pressure reduction suckion remover is absorbed to manage with sealing block by the dirty slag that all is parallel to the filter core cylinder setting and is formed,
(2) absorb infratubal port and join with the atmosphere or the potential source of doing something in a fit of pique, towards the tube wall of filter core cylinder one side have break slot from top to bottom, this break slot edge is a boss,
(3) sealing block places filter core cylinder and absorbs between the pipe, the one side have rectangular groove sliding sleeve on the break slot boss of absorbing pipe, an opposite side replaces on the filter core cylinder outer wall, is a groove cavities between sealing block and filter core cylinder outer wall.
Being covered with the cross section that keeps pitch to twine on the cylindrical tube of rectangular slotted eye and the outer wall thereof on such scheme basis upper filter tube can be by a sidewall vertically is that wedge shaped wires is formed.Peg graft with the locating hole on the casing upper cover in absorption pipe in pressure reduction suckion remover upper end, lower port is crimped on by sealing gasket in casing and leans out on the drainage tube upper port that casing can communicate with atmosphere.
The utility model utilizes in the filter core clean liquid to the recoil of filter core hole and finish to the cleaning of filter core, and this recoil strength then is formed with the pressure differential in the recoil sealing block groove of connecting atmosphere by the pressure of clean liquid in the filter core.The low speed rotation of the doing filter core sealing block that recoils then slides on the gap boss of the absorption pipe that is communicated with atmosphere.The groove surface of recoil sealing block is to filter core, and overleaf under the effect of soiling solution pressure, the recoil sealing block is pressed on the filter core, make groove isolated with soiling solution and only with the filter core inner chamber, absorb tube cavity and be connected, like this, just having created the condition of necessity of recoil cleaning.
The utility model advantage is: simple and reasonable for structure, removed scraper plate of the prior art and counterbalance spring.Saving scraper plate can avoid dwindling seam aperture on the filter core barrel, guarantee to filter operating efficiency; As filter core cylinder and the sealing block of removing connector between the pipe by in the casing with filter core in hydraulic pressure difference and be adjacent to all the time automatically on the filter core barrel, need not the artificial counterbalance spring of constantly adjusting with the application of force.
Fig. 1 is the utility model embodiment general structure schematic diagram.
Fig. 2 is an A-A cross section structure schematic diagram among Fig. 1.
Fig. 3 is a B portion structure for amplifying schematic diagram among Fig. 2.
Below in conjunction with drawings and Examples the utility model is done further narration:
As shown in the figure, the liquid filter among the utility model embodiment is made up of the wedge type steel wire 4 on motor driver 1, loam cake 2, filter core cylinder 3, tube 3 outer walls, support bar 5, base 6, casing 7, drainage tube 8, sealing gasket 9, absorption pipe 10, sealing block 11, torsion spring 12, locating piece 13.
Fig. 1 and Fig. 2 have showed representative instance of the present utility model: filter core 3 is to be covered with slotted hole on the face of cylinder, the hot finished steel pipe that twine by a constant pitch with wedge-section wire 4 outside, and there is shaft extension at steel pipe two ends all welding-on, and following shaft extension cooperates with deep groove ball bearing and is loaded in the base 6; Last shaft extension constitutes by two sections, hypomere is a hollow shaft, and have four slotted holes as clean liquid outlet, its position, assembling back is in the clean sap cavity of loam cake 2, epimere then matches with cylinder roller bearing in the loam cake, and is shaped on hole and the keyway that matches with the shaft extension of motor driver 1 in the upper end.
