In the following description, many specific details are provided to provide a full understanding of the embodiments of the present utility model. However, those skilled in the art will appreciate that the technical solution of the present utility model can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those shown or described.

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Some embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] In order to drain the filter without stopping the equipment, an embodiment of the utility model provides a double Y-type filter that can be quickly flushed. The filter is filtered by setting at least two filter components. When one of the filter components is blocked for draining, the other filter components can work normally, thereby not affecting the normal operation of the equipment.

[0030] Specifically, the filter includes: a main pipe and at least two filter components;

[0031] The main pipe is provided with a water inlet and a water outlet;

[0032] The at least two filter assemblies are installed on the main pipe, and the at least two filter assemblies are in communication with the main pipe;

[0033] The filter assembly comprises a filter section and a drain valve, the head of the filter section extends into the interior of the main pipe, and the drain valve is arranged at the tail of the filter section;

[0034] Wherein, the filter segment heads of the at least two filter components are connected to each other.

[0035] It can be understood that, in the embodiment of the utility model, the at least two filter components provided can ensure that when one filter component needs to discharge sewage, there is at least one other filter component that takes on the task of filtering the water supply.

[0036] It is understandable that in the embodiment of the utility model, the filter segment heads of at least two filter components are connected to each other to form a closed filter structure, thereby avoiding the existence of a gap between the two filter segment heads, causing part of the water to flow to the outlet without being filtered.

[0037] It is understandable that in the embodiment of the utility model, when the filter assembly performs filtering work normally, the drain valve is in a closed state. When the filter section is blocked, the drain valve can be opened to achieve sewage treatment of the filter section.

[0038] In some feasible embodiments, based on the aforementioned solution, the at least two filter components include: a first filter component and a second filter component;

[0039] The first filter assembly and the second filter assembly are symmetrically mounted on the main pipe.

[0040] It is understandable that two filter components are the minimum requirement for the present filter. In other embodiments, the present filter may include three filter components, four filter components, and so on. Of course, no matter how many filter components are provided, it should be ensured that the heads of each filter component are connected to each other to form a closed filter structure to ensure that the water flow in the main pipe can be completely filtered.

[0041] In some feasible embodiments, based on the above solution, a first interface and a second interface are symmetrically provided at one end of the main pipe close to the water inlet;

[0042] The first filter assembly is installed on the first interface;

[0043] The second filter assembly is installed on the second interface.

[0044] It is understandable that the number of interfaces varies according to the number of filtering components.

[0045] For example, see Figure 1 , shows a schematic structural diagram of a quickly flushable double Y-type filter according to an embodiment of the utility model.

[0046] like Figure 1As shown, a quick-rinsing double Y-type filter is shown, comprising: a main pipe 1, with a water inlet and a water outlet at both ends; two interfaces are symmetrically opened at one end of the main pipe 1 close to the water inlet, and two filter components are respectively installed on one interface, and are symmetrically arranged on both sides of the main pipe 1.

[0047] like Figure 1 As shown, the filter assembly includes a filter section 2 and a drain valve 3; wherein the head of the filter section 2 extends into the interior of the main pipe 1, and the heads of the two filter sections are connected to each other to form a closed filter structure to prevent the water from flowing to the outlet without being filtered; the drain valve 3 is arranged at the tail of the filter section 2, and the filter section 2 can be drained by opening the drain valve 3.

[0048] In some feasible embodiments, based on the above-mentioned solution, the filter section is made of a filter mesh.

[0049] It can be understood that the filter screen is the simplest and most efficient filtering device, which meets the filtering requirements of the present invention.

[0050] In some feasible embodiments, based on the above-mentioned solution, the drain valve adopts a manual valve or an electric valve.

[0051] It is understandable that manual valves need to be opened and closed manually, which is relatively time-consuming, labor-intensive, and labor-intensive, but their cost is lower. Although electric valves can be opened and closed automatically, they still require a matching control system, which increases costs and system complexity.

[0052] In some feasible embodiments, based on the above scheme, when the drain valve adopts an electric valve, a differential pressure sensor for obtaining the differential pressure between the water inlet and the water outlet is provided on the main pipe, and a controller is connected to the drain valve, and the differential pressure sensor is connected to the controller.

[0053] It can be understood that the pressure difference between the water inlet and the water outlet is obtained by respectively arranged pressure difference sensors, and the controller controls the switch of the sewage valve according to the pressure difference.

[0054] For example, Figure 1 As shown, the two ends of the pressure difference sensor 4 are respectively located at the water inlet and the water outlet, and the pressure difference between the water inlet and the water outlet is obtained. The pressure difference sensor 4 is connected to the controller 5, and the pressure difference information is transmitted to the controller 5. The controller 5 is also connected to the sewage valve 3, and the switch of the sewage valve 3 is controlled according to the pressure difference information; for example, a pressure difference threshold is set, the pressure difference information is compared with the pressure difference threshold, and the sewage valve 3 is controlled according to the comparison result.

[0055] In summary, the filter provided in the embodiment of the utility model adopts a double filter screen or a multi-filter screen structure, which can ensure that the filter screen can be cleaned without stopping the equipment.

[0056] By installing a drain valve at the end of the filter section, the drain function of the equipment is realized, and the structure is simple and practical.

[0057] The drain valve is replaced with an electric valve, and a pressure difference sensor and controller are installed before and after the filter to achieve automatic draining.

[0058] Those skilled in the art will readily come up with other embodiments of the present invention after considering the specification and practicing the embodiments disclosed herein. The present invention is intended to cover any variations, uses or adaptations of the present invention, which follow the general principles of the present invention and include common knowledge or customary technical means in the art that are not disclosed in the present invention. It should be understood that the present invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
