Detailed description of the invention

Referring to figs. 1 through Fig. 3, the utility model filter embodiment is described further.

A kind of filter, comprise chimney filter 1, the filter screen 4 of tubular is provided with in chimney filter 1, filter screen 4 is vertically arranged in chimney filter 1, one end of filter screen 4 is positioned at chimney filter 1 top, be tightly connected with the opening of chimney filter 1, the other end abuts with arrangement cap 5, chimney filter 1 is provided with water inlet pipe 2 and outlet pipe 3, water inlet pipe 2 is arranged on filter screen 4 top, the opening of filter screen 4 aims at water inlet pipe 2, water inlet pipe 2 communicates with the inner chamber of chimney filter 1, because the filter screen 4 of tubular and the opening of chimney filter 1 seal to arrange, when current enter in chimney filter 1 in water inlet pipe 2 time, current all enter in the filter screen 4 of tubular, after entering the filtration of screen pack 4, discharge from the outlet pipe 3 be connected with chimney filter 1, detachably be fixed with bottom chimney filter 1 and settle cap 5, settle cap 5 to adopt with chimney filter 1 to be threaded, chimney filter 1 is provided with external screw thread, arrangement cap 5 is provided with the internal thread coordinated with external screw thread, be threaded connection and realize settling the detachable fixing of cap 5, not only good sealing effect, and convenient disassembly, filter screen 4 is connected in be settled in cap 5, the counterbore 53 equal with filter screen 4 external diameter is provided with in arrangement cap 5, support frame 41 is provided with in filter screen 4 outside, the shape of skeleton is tubular, filter screen 4 is fixedly installed on skeleton, counterbore 53 sidewall is provided with scrobicular ring 531, skeleton is provided with the bulge loop 43 coordinated with scrobicular ring 531, by coordinating of scrobicular ring 531 and bulge loop 43, filter screen 4 is connected to and settles in cap 5, when replacing filter screen 4, arrangement cap 5 is only needed to pull down, filter screen 4 is taken out in arrangement cap 5, achieve the replacing of filter screen 4 very easily, conveniently mounting filter, in the present embodiment, water inlet pipe 2 and outlet pipe 3 conllinear are arranged, outlet pipe 3 is arranged on the sidewall of chimney filter 1.

When the impurity buildups of filter screen 4 is to after certain degree, filter screen 4 is easily caused to block, reduce the strainability of filter screen 4, therefore, mud hole 51 is provided with bottom arrangement cap 5, mud hole 51 communicates with counterbore 53, leak to prevent the current in chimney filter 1, the seal member for closed mud hole 51 is also provided with bottom arrangement cap 5, under normal condition, mud hole 51 is in sealing state, filter filters work normally, when needs carry out deslagging, mud hole 51 is opened, the current of filter screen 4 are now flowed into from water inlet pipe 2, the function of flushing can also be played to the impurity settled in cap 5, promote the outflow of impurity, play very good cleaning effect, and, in the use of reality, even if mud hole 51 is opened, aperture due to mud hole 51 is the aperture being less than water inlet pipe 2, therefore, can also be in running order in chimney filter 1, the flow just flowed out from outlet pipe 3 can reduce, therefore, when deslagging, filter still can be in running order.

In order to make to keep sealing state between filter screen 4 and chimney filter 1, support frame 41 is provided with O-ring seal 42, O-ring seal 42 is arranged on the two ends up and down of the filter screen 4 of tubular, O-ring seal 42 is arranged on the face that support frame 41 contacts with chimney filter 1, O-ring seal 42 is set, the current that prevent of effect first spilt before entering filter screen 4, avoiding foreign material from leaking bottom filter screen 4 in outlet pipe 3, improve the reliability of filter.

Conveniently screwed off by arrangement cap 5, be provided with anti-skidding lines 7 at arrangement cap 5 outer surface, anti-skidding lines 7 can increase hand and settle the frictional force between cap 5, avoid due to settle cap 5 screw after the situation that cannot unscrew occur.

In the present embodiment, be provided with in arrangement cap 5 outside the scum pipe 52 communicated with mud hole 51, scum pipe 52 is wholely set with settling cap 5, and seal member comprises the seal cover 6 be threaded with scum pipe 52, when needs open scum pipe 52 time, seal cover 6 is screwed off.

Conveniently filter is accessed in chimney filter 1, external screw thread is provided with away from one end of chimney filter 1 at water inlet pipe 2 and outlet pipe 3, screw-internal thread fit on external screw thread and exterior line, conveniently water inlet pipe 2 and outlet pipe 3 screw, water inlet pipe 2 with outlet pipe 3 are equipped with the operating block 8 for fastening chimney filter 1, operating block 8 is provided with operating surface 81 parallel to each other, operating surface 81 can exert a force by convenient wrench, for wrench operated provides reliable stress point, realize the dismounting of water inlet pipe 2 very easily and fix.

Below be only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
