Be the front end preprocessor of explanation about water purification system herein, this preprocessor is to be connected on the water purification system front end, it is made of the built-in filter core of a body, and the body upper and lower side is respectively equipped with water inlet and delivery port, current are flowed out by the delivery port that water inlet enters in the body after the filtration of filter core by body again, and the structure of this unidirectional filtration relies on the saturation degree of the unidirectional filtration of filter core fully and determines life-span of filter core, so the service life of filter core is shorter, increases the use cost of front end preprocessor.And actual filter core to this coarse filtration carries out back flush, the impurity of big grain can be disposed from filter core, filter core after being cleaned still has certain filtering function, and the preprocessor of this structure only is unidirectional filtering function at present, and can't realize reverse washing capacity and effectively utilize filter core.

The utility model content

The purpose of this utility model provides a kind of filter core that increases and locates device in advance with the front end that reduces use cost service time.

Be practical above-mentioned purpose, solution of the present utility model is: a kind of front end preprocessor, and it comprises the body of a built-in filter core; Wherein: this body top forms uncovered, this is uncovered to be sealed and matched by a three-way switch valve, the deduction of the lower end of this transfer valve in the upper end of filter core so that filter core is fixed in the body, a water route of transfer valve is to communicate with the filter core inner chamber, and another water route is to communicate with the chamber that inner body wall forms with filter core.

Be respectively equipped with water inlet, delivery port and sewage draining exit on the described three-way switch valve periphery, whether communicate to switch between each mouthful by the handle rotary spool.

Be equipped with the joint of a tool switch on the described sewage draining exit.

After adopting such scheme, front end preprocessor of the present utility model, on body, connect cooperating of the triple valve established and body and filter core, can make current that forward and reverse variation are arranged on the operating path between body and the filter core by switching this triple valve, thereby to the certain cleaning action of having of filter core, realize prolonging filter core service life with this, reduce the effect of use cost.

The specific embodiment

As shown in Figure 1, front end preprocessor of the present utility model is provided in a side of the front end of water purification system.It is made of a body 1, a filter core 2 and a transfer valve 3;

This body 1 is a cylindrical shell, and its upper end forms uncovered 11; Filter core 2 is a column casing, and it is built on the axis in the body 1, and the lower end leans the lower surface at body 1, and the upper end is by transfer valve 3 deductions, transfer valve 3 be movable sealing be matched with body 1 uncovered 11 on.

This transfer valve 3 is triple valves that periphery is distributed with water inlet 31, delivery port 32 and sewage draining exit 33, whether water route between three mouths communicates and drives valve core rotation by handle 34 and control, the position that corresponding handle 3 switches on the valve body of transfer valve 3 is provided with the work sign, with handled easily; Be about to filter core 2 and be fixed in the body 1 when upper end at filter core 2 of transfer valve 3 lower ends deductions, a water route of transfer valve 3 is to communicate with filter core 2 inner chambers, and another water route is to communicate with the chamber of filter core 2 with the formation of body 1 inwall.Water inlet 31 is to connect water inlet pipe, and delivery port 32 connects outlet pipe and enters down the road purifier, and 33 of sewage draining exits connect one and have the joint 5 of gauge tap 4 to connect sewage-treatment plant.

As shown in Figure 2, when this preprocessor carries out normal filtration work, pull handle 34 and aim at run location, it is communicating state with delivery port 32 that spool switches water inlet 31, the sewage draining exit 3 of this moment can water outlet for closed condition because of gauge tap 4, and then current can be introduced into the inner chamber of filter core 2 from water inlet 31, and immerses in the chamber that filter core 2 and body 1 form, delivery port 32 from body 1 top transfer valve 3 flows out again, so promptly finishes a filter process of water.

After filter core uses a period of time, if when filter core is cleaned, cooperate shown in Figure 3, handle 34 turned to just wash the position, open the gauge tap 4 of sewage draining exit 33, water inlet 31 is a communicating state with sewage draining exit 33, and delivery port 32 is a closed condition, the water route of water inlet 31 is the chambers that lead between filter core 2 and the body 1, flow to the inner chamber of filter core 2 again, and enter transfer valve 3 from filter core 2 tops and flow out from sewage draining exit 33, these current can effectively effectively wash down the part impurity on the filter core 2 and flow out with current the reverse flow of filter core 2.

Again as shown in Figure 4, be the effect that guarantees that filter core 2 cleans, forward cleans it again, be about to handle 34 and turn to the backwash position, open the gauge tap 4 of sewage draining exit 33, water inlet 31 is a communicating state with sewage draining exit 33, delivery port 32 is similarly closed condition, the water route of water inlet 31 of this moment is that the inner chamber that leads to filter core 2 flows to the chamber between filter core 2 and the body 1 again, and enters transfer valve 3 from sewage draining exit 33 outflows, with further cleaning filter core 2 from body.

To sum up, the utility model makes this preprocessor not only have the function that purifies water by to the improvement of front end preprocessor structure and the setting of cooperation three-way switch valve 3, also has the function of cleaning filter core 2, prolong 2 service lifes of filter core to reach, reduce the effect of use cost.
