Description
Technical Field
The utility model relates to a water mixing tank.
Background
As disclosed in patent No. 201420617289.7, the existing water mixing tank has a tank body wrapped in an EPS heat-insulating layer, a water inlet and at least one water outlet are provided on a side wall of the tank body, a filter member located between the water inlet and the water outlet is provided inside the tank body, an upper end and a lower end of the tank body are gradually closed to form a gas collection chamber and a slag removal chamber, respectively, the gas collection chamber is connected with the outside through an automatic exhaust valve, and the slag removal chamber is connected with the outside through a blow-down valve; the lateral wall of the tank body is also provided with a by-pass port which is positioned at the same side of the filter piece with the water inlet. In the structure, the filtering piece has a larger water resistance effect between the primary pipeline and the secondary pipeline, so that the water circulation effect inside the primary pipeline and the secondary pipeline is enhanced, and the heat transfer effect of the water mixing tank is reduced; and in fact, because filter vertical setting, the rivers direction between primary pipeline, the secondary pipeline does not keep invariable constantly, consequently filters the attached filth of filter both sides and can be washed away when different rivers directions to continue to participate in hydrologic cycle, make the filter effect in fact relatively poor.
Disclosure of Invention
The utility model aims to solve the above problem, provide a better and muddy water pitcher that has filtering capability of heat transfer effect between primary pipeline and the secondary pipeline, specifically realized by following technical scheme:
a water mixing tank comprises a tank body, a first filter screen, a second filter screen, a filter element, a water pump and a three-way valve, wherein a primary water inlet pipe and a primary water return pipe which are positioned on one side, and a secondary water return pipe and a secondary water inlet pipe which are positioned on the other side of the side wall of the tank body are arranged on the side wall of the tank body; a cleaning pipe is longitudinally inserted in the middle of the tank body, the upper end of the cleaning pipe extends to the outside of the tank body, a water inlet of the water pump is connected with the upper part of the cleaning pipe through a pipeline, the filter element is inserted in the cleaning pipe from the upper end of the cleaning pipe, a water outlet of the water pump is connected with the three-way valve, and the three-way valve is respectively connected with the primary water return pipe and the secondary water return pipe through pipelines; the first filter screen and the second filter screen are respectively arranged at the pipe orifices of the primary water return pipe and the secondary water return pipe in the tank body.
The water mixing tank is further designed in that the diameter of the middle part of the inner wall of the cleaning pipe is shrunk to form a flow limiting part, the cleaning pipe is inserted in the flow limiting part, and the inner diameter of the flow limiting part is equal to the diameter of the filter element.
The water mixing tank is further designed in that the filter element is a cylindrical body with a honeycomb structure.
The utility model has the advantages that:
the utility model discloses utilize first filter screen, second filter screen setting at a wet return, secondary wet return, in the long-term circulating water filterable in to two pipelines, utilize the filter core to carry out the back flush circulation and intercept the filtrations at mixing water tank off state to first filter screen, second filter screen, realize the filter effect to the circulating water.

Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
the water mixing tank comprises a tank body 1, a first filter screen 2, a second filter screen 3, a filter element 4, a water pump 5 and a three-way valve 6, wherein a primary water inlet pipe 11 and a primary water return pipe 12 which are positioned on one side, and a secondary water return pipe 13 and a secondary water inlet pipe 14 which are positioned on the other side of the side wall of the tank body are arranged on the side wall of the tank body; a cleaning pipe 7 is longitudinally inserted in the middle of the tank body, the upper end of the cleaning pipe extends to the outside of the tank body, a water inlet of the water pump is connected with the upper part of the cleaning pipe through a pipeline, the filter element is inserted in the cleaning pipe from the upper end of the cleaning pipe, a water outlet of the water pump is connected with the three-way valve 6, and the three-way valve is respectively connected with the primary water return pipe and the secondary water return pipe through pipelines; the first filter screen and the second filter screen are respectively arranged at the pipe orifices of the primary water return pipe and the secondary water return pipe in the tank body.
In the embodiment, the first filter screen and the second filter screen are arranged on the primary water return pipe and the secondary water return pipe, when circulating water in two pipelines is filtered for a long time, the three-way valve is communicated with the cleaning pipe and the primary water return pipe or the secondary water return pipe under the stop state of the water mixing tank, the water pump is started, and the filter element is used for performing back flush circulation on the first filter screen and the second filter screen and intercepting filter matters in the stop state of the water mixing tank, so that the filtering effect on the circulating water is realized; during the normal operation of water mixing tank, because the filter core setting is inside the scavenge pipe, the filth in the filter core can not participate in hydrologic cycle, uses a period after at the filter core, extracts the filter core from the scavenge pipe, washs or changes the filter core.
Specifically, the diameter of the middle part of the inner wall of the cleaning pipe 7 is contracted to form a flow limiting part 71, the cleaning pipe is inserted in the flow limiting part, and the inner diameter of the flow limiting part is equal to the diameter of the filter element. The filter element is a cylindrical body with a honeycomb structure.
