Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a conversion-free bidirectional flushing and disassembly-free filter. Background Art

[0002] Filters, as a device for purifying water, are very popular and recognized in the market. The purification method is that raw water enters the filter from the water inlet, passes through the filter element inside the filter, and the filter element filters the solid particle impurities in the raw water on the outside of the filter element. The water enters the inside of the filter element and is finally discharged from the outlet of the filter, thereby purifying the water quality. The filter element inside the filter that has been used for a long time needs to be removed for cleaning, which is very inconvenient.

[0003] In order to reduce the difficulty of cleaning the filter element, filters that can clean the internal filter element without removing the outer shell are introduced on the market. The Chinese utility model patent with the authorization announcement number CN208561785U discloses a filter, which has a wastewater port at the bottom. When cleaning the internal filter element, water enters from the water inlet on the upper side of the outer shell, enters from the upper pipe port of the ultrafiltration membrane wire tube of the filter element, and then flows out from the lower pipe port of the ultrafiltration membrane wire tube, thereby flushing out the impurity particles from the ultrafiltration membrane wire tube. Although this structural design can flush out the impurity particles in the ultrafiltration membrane wire tube and achieve the cleaning effect inside the ultrafiltration membrane wire tube; however, since the ultrafiltration membrane wire tube has a long pipeline and the ultrafiltration membrane wire tube itself has a certain elasticity, the impurity particles in the ultrafiltration membrane wire tube are prone to clogging. For this reason, we propose a conversion-free two-way flushing and disassembly-free filter. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a conversion-free, bidirectional flushing and disassembly-free filter.

[0005] To achieve the above object, the utility model adopts the following technical solution: a conversion-free two-way flushing and disassembly-free filter, comprising a shell and a shell cover, wherein the shell cover is sealed on the cavity of the shell, and a cavity for accommodating a filter element is formed between the shell cover and the shell.

[0006] The filter is provided with a first raw water inlet, a second raw water inlet, and a purified water outlet disposed between the first raw water inlet and the second raw water inlet;

[0007] The filter element is provided with a first filter part and a second filter part at both ends, and the first filter part and the second filter part are provided with a plurality of ultrafiltration membrane wire tubes. The filter is also provided with a first sewage outlet at the first filter part, and the filter is also provided with a second sewage outlet at the second filter part;

[0008] An intermediate connecting portion for connecting the first filter portion and the second filter portion is provided between the first filter portion and the second filter portion, and the intermediate connecting portion is provided with an intermediate opening for connecting to the purified water outlet. The first raw water inlet is located at the first filter portion, and the second raw water inlet is located at the second filter portion.

[0009] It is further explained that the ultrafiltration membrane wire tubes at the first filter part and the second filter part are both U-shaped.

[0010] It is further explained that the filter element is provided with a first sealing ring between the first filter part and the middle opening, and the filter element is provided with a second sealing ring between the second filter part and the middle opening, and the first sealing ring and the second sealing ring are H-shaped or O-shaped.

[0011] It is further explained that the shell is provided with a shoulder portion for supporting the filter element, a limiting cylinder is provided between the upper end of the filter element and the shell cover, the upper end of the limiting cylinder is in conflict with the shell cover, the lower end of the limiting cylinder is in conflict with the filter element, the limiting cylinder is sleeved on the first filter portion of the filter element, and the limiting cylinder is provided with a water outlet.

[0012] It is further explained that the shell is provided with a shoulder portion for supporting the filter element, and the filter element is provided with a limiting rod portion at the first filter portion, and the upper end of the limiting rod portion is in conflict with the shell cover.

[0013] The beneficial effects of the utility model are as follows: the utility model adopts a filter element in which the first filter part and the second filter part are independently arranged. Since the impurity particles of the raw water are blocked on the outside of the first filter part and the outside of the second filter part of the filter element during water filtering, the impurity particles of the raw water do not enter the tube of the ultrafiltration membrane wire tube. The first raw water inlet, the second raw water inlet, the clean water outlet, the first sewage outlet and the second sewage outlet are independent of each other, and there is no need to use a conversion joint. The entire filter does not need to remove the filter element inside it to achieve cleaning of the filter element, and the operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
