Abstract

The utility model relates to a filter, which comprises a tank body, a sand collecting tank, a water inlet pipe and a water outlet pipe, wherein the sand collecting tank is just below the tank body and connected with the tank body; the water inlet pipe and the water outlet pipe are connected to the outside surface of the tank body; the tank body comprises a centrifugal tank and a built-in net type filter; the central axial lines of the centrifugal tank and the built-in net type filter are coincident; the net type filter is fixedly connected with the centrifugal tank through at least one steel frame. Because the net type filter is arranged in the centrifugal tank, first-stage filtering and second-stage filtering can be simultaneously completed in the tank body, therefore, the original equipment can be effectively simplified; the mass and the volume of the filter are greatly reduced; the carrying and installing costs of the filter can also be effectively reduced.

Description

A kind of filter

Technical field

The utility model relates to a kind of filter, especially relates to a kind of for purifying the filter of irrigation water.

Background technology

Scarcity day by day along with global freshwater resources, now, irrigate field no matter be in field of agricultural irrigation or gardening, drip irrigation or the sprinkling irrigation mode of saving water resource have more been adopted gradually, these two kinds of irrigation methods are all, by the water outlet at water pipe, mini sprinkler is installed, water yield is reduced, thereby reach, take full advantage of the purpose of utilizing water resource.

Yet, if be mixed with impurity in the water in water pipe, these impurity probably arrive described mini sprinkler place along current so, in the course of time, the impurity that pile up at the mini sprinkler place will stop up mini sprinkler, thereby makes the inefficiency of described drip irrigation or sprinkling irrigation.

For solving the blocked problem of above mini sprinkler, people have expected utilizing filter to filter out the method for impurity in water before current enter water pipe.The existing filter in market is centrifugal net filter, and its main body is comprised of centrifugal tank body and well strainer two parts, during work, at first by centrifugal tank body, the sand grains in water or contaminant filter is fallen, and completes the first order and filters; By well strainer, contaminant filter less in water is fallen, complete the second level and filter, filtered water finally flows to delivery port.

Although described centrifugal net filter can complete the filtration work of water, because it forms complexity, quality and volume are larger, and peasant's cost when carrying and this filter is installed is higher.

Summary of the invention

In view of this, the utility model provides a kind of filter, and to solve, existing centrifugal net filter forms complicated, quality and volume is large, carrying and the higher problem of installation cost.

For achieving the above object, the utility model is by the following technical solutions:

A kind of filter, comprise tank body, be positioned at the positive lower end of tank body connected sand collecting tank, the water inlet pipe that is connected in described tank body outer surface and outlet pipe, it is characterized in that, described tank body comprises tophan box and is built in well strainer wherein, and the two axis overlaps, described well strainer is fixedly connected with tophan box by least one steelframe, with tophan box, forms annular centrifugal chamber.

Preferably, described filter also comprises the Pressure gauge on the pipeline that is positioned at described water inlet pipe.

Preferably, described filter also comprises the Pressure gauge on the pipeline that is positioned at described outlet pipe.

Preferably, described filter also comprises the air bleeding valve on the pipeline that is positioned at described outlet pipe.

Preferably, described filter also comprises the support be fixedly connected with described sand collecting tank.

Preferably, described well strainer is made by 120 order stainless steel wire meshes.

Preferably, the axis of the axis of the axis of described water inlet pipe and described tophan box and well strainer is all non-intersect.

Preferably, described tophan box and well strainer is shaped as a kind of in cylinder or cone.

Because described well strainer is placed in tophan box, can in described tank body, complete first order filtration and the second level simultaneously and filter, therefore, can effectively simplify existing equipment, quality and the volume of described filter are reduced greatly, and its carrying correspondingly with installation cost also effectively reduces.

The specific embodiment

Below in conjunction with Fig. 1 to Fig. 3, the technical scheme in the utility model embodiment is clearly and completely described.

Fig. 1 is the overall structure schematic diagram of the utility model embodiment middle filtrator.As shown in the figure, described filter comprises tank body 10, is positioned at the positive lower end of tank body connected sand collecting tank 40, the support 50 that supports described sand collecting tank, the water inlet pipe 20 that is connected in described tank body outer surface and outlet pipe 30.

For guaranteeing the safe operation of filter, described filter also is included in the Pressure gauge 21 of installing on the pipeline of described water inlet pipe 20 and the Pressure gauge 31 of installing on the pipeline of described outlet pipe 30, is respectively used to monitor the water flow pressure of water inlet pipe 20 and outlet pipe 30; Air bleeding valve 32 also is installed on the pipeline of described outlet pipe 30, for getting rid of the air in pipeline, prevents that air from producing pneumatic hammer, produces compression failure to pipeline.

Fig. 2 is the top view of the utility model embodiment middle filtrator tank body, and Fig. 3 is the cut-away view of the utility model embodiment middle filtrator.As shown in Figure 2, described tank body 10 comprises tophan box 11 and is built in well strainer 12 wherein, the two be shaped as a kind of in cylinder or cone, and the axis L1 of the two and L2 overlap, therefore, formed a centrifugal chamber 13 of annular in the inside of described tank body 10, for water is carried out to first order filtration; Described well strainer 12 is made by 120 order stainless steel wire meshes, and is fixedly connected with tophan box 11 by least one steelframe 121.

Described water inlet pipe 20, outlet pipe 30 all are connected with tophan box 11, as shown in Figure 2, described water inlet pipe 20 is configured to bias, that is, the axis L2 of the axis L3 of described water inlet pipe 20 and the axis L1 of described tophan box 11 and well strainer 12 is all non-intersect, therefore, after current flow into tophan box 11 along water inlet pipe 20 to direction shown in arrow a, can nature along direction spinning shown in arrow c, thereby produce an eddy current, simultaneously, produce the centrifugal force towards described tophan box 11 inwalls; Because the density ratio water of sand is large, in the centrifugal field of same fixed size, sinking speed is also large than water, therefore, under the effect of described centrifugal force, the sand grains be mingled in water is separated on the inwall of described tophan box 11, and simultaneously, sand grains is under the self gravitation effect, inwall along tophan box 11 sinks in sand collecting tank 40, thereby completes the sand separation of first order water.

As shown in Figure 3, after current have separated the sand separation of first order water due to spinning by the sand grains mixed in water, current can be along direction ecto-entad shown in arrow d in figure by described well strainer 12, as mentioned above, described well strainer 12 consists of 120 order stainless steel wire meshes, when current flow through wire netting, the impurity that is greater than wire netting web-roll core aperture will be trapped within on the outer surface of described well strainer 12, complete the second level and filter; Water after filtration flows out along outlet pipe 30 to direction shown in arrow b, thereby, completed that the first order is filtered and second level filtration described tank body 10 is interior simultaneously.

As mentioned above, described well strainer 12 is built in tophan box 11, can complete that the first order is filtered and second level filtration described tank body 10 is interior simultaneously, thereby effectively simplify existing equipment, quality and the volume of described filter are reduced greatly, and its carrying correspondingly with installation cost also effectively reduces.
