Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 3, the present invention includes a vertically through casing 1, an inner cylinder 201 is coaxially fixed in the middle of the casing 1, an enclosure 202 inclined inward is fixed on the upper end of the inner cylinder 201, and a first filter screen 203 is fixed on the upper end of the enclosure 202; the inner cylinder 201, the enclosure 202 and the first filter screen 203 form a filter body 2 with a downward opening; a cross rod 3 positioned above the filter body 2 is arranged on the shell 1, and the cross rod 3 can move up and down along the shell 1; a vertical rod 4 is fixed in the middle of the cross rod 3, a water-stop sheet 5 arranged in the filter body 2 is fixed at the lower end of the vertical rod 4, and the shape of the water-stop sheet 5 is consistent with that of the first filter screen 203; an annular baffle 6 is fixed below the cross rod 3, and the annular baffle 6 can block the interval between the first filter screen 203 and the inner side wall of the shell 1;

the lower part of the shell 1 is in threaded connection with a detachable end socket 7, a water outlet pipe 8 is arranged on the end socket 7, a horizontal second filter screen 9 is arranged in the end socket 7, and the second filter screen 9 can be simultaneously contacted with the lower ends of the inner barrel 201 and the shell 1.

In order to realize the up-and-down movement of the cross rod 3, the side wall of the shell 1 is provided with a left vertical abdicating groove 10 and a right vertical abdicating groove 10, and the cross rod 3 is arranged in the left vertical abdicating groove 10 and the right vertical abdicating groove 10; the left end and the right end of the cross rod 3 are respectively supported by electric telescopic rods.

In order to fix the inner barrel 201, the inner barrel and the shell 1 are connected through a plurality of reinforcing ribs 11.

In order to avoid liquid leakage at the abdicating groove 10, the cross bar 3 is fixed with a left vertical plate 12 and a right vertical plate 12 which block the abdicating groove 10.

In order to better realize sliding and positioning, an annular positioning plate 13 is connected to the outer edge surface of the annular baffle 6, and the positioning plate 13 is attached to the inner wall of the shell 1.

When the utility model is used, firstly, the electric telescopic rod is in a contracted state, namely, the whole device is as shown in the attached figure 2, at the moment, the water-stop sheet 5 is positioned below the first filter screen 203, and due to the design of the annular enclosure 202, when the water-stop sheet 5 is positioned below the first filter screen 203, a gap is reserved between the outer edge surface of the water-stop sheet 5 and the inner side wall of the inner cylinder 201, so that the filtered liquid can flow downwards conveniently; meanwhile, the annular baffle 6 is in a state of blocking the interval between the filter screen and the shell 1; that is, the liquid to be filtered cannot flow out from the space between the filter net and the housing 1, that is, the space between the inner cylinder 201 and the housing 1.

At this moment, after the cutting water to be filtered flows from top to bottom, the cutting fluid flows to the first filter screen 203 under the collecting action of the annular baffle 6, flows into the inside of the filter body 2 after being filtered by the first filter screen 203, flows through the water-stop sheet 5, is filtered by the second filter screen, finally flows into the seal head 7, and flows out through the water outlet pipe 8.

The impurities are mainly remained on the first filter 203, and the second filter 9 has only a few impurities, so that the use is not affected.

After a period of time, the first filter screen 203 is blocked, and at the moment, the two electric telescopic rods are started simultaneously to move upwards, so that the cross rod 3 moves upwards, and after the cross rod 3 moves upwards, the water-stop plate 5 and the annular baffle 6 are driven to move upwards simultaneously; and the water stop plate 5 blocks the first filter 203 and the baffle 6 opens the space between the outer edge surface of the first filter 203 and the inner wall of the housing 1. At this time, the cutting water with filtering cannot pass through the first filter screen 203, and only flows downwards from the space after the first filter screen 203 is washed; and after being filtered by a second filter screen 9, the water flows into the seal head 7 and flows out through a water outlet pipe 8.

Through the scouring of the cutting water, the first filter screen 203 can be dredged without being blocked, and meanwhile, sundries above the first filter screen can be scoured into the space between the inner barrel 201 and the shell 1; so that the sundries are collected; without affecting the primary filtering action of the first screen 203.

Then the cross rod 3 is reset, so that the continuous high-efficiency filtering of the first filter screen 203 can be realized.

When the cleaning is needed, the seal head 7 is opened for cleaning.

The first washing of the first filter screen 203 can be realized by moving the cross rod 3 up and down for one time, and impurities are collected in the interval between the inner barrel 201 and the shell 1, so that the filtering effect of the first filter screen 203 is not influenced.

The device is provided with two passages and is switched by moving up and down; the sundries in the first filter screen 203 are collected into the interval between the inner barrel 201 and the shell 1; therefore, the main filtering effect and efficiency of the first filter screen 203 are not affected, the service time of the filter screen is prolonged, and frequent blockage is avoided.

This device comes to carry out complete shutoff to the filter screen through water-stop sheet 5 to make cutting water can't pass first filter screen 203, consequently can realize washing away of first filter screen 203, can utilize the scouring force of cutting water to make first filter screen 203 obtain abundant washing away, do benefit to subsequent filtration, realized long-time work.

In the device, sundries and cutting water collected between the inner barrel 201 and the side wall of the shell 1 can be slowly filtered by the second filter screen 9 without hindering the high-efficiency filtration of the first filter screen 203; meanwhile, the cutting water with large impurity content can be slowly filtered, and the recovery rate and the efficiency are improved.
