Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and particularly relates to a Y-type filter which is easy to clean. Background Art

[0002] Y-type filter is a commonly used pipeline filter, which is shaped like the letter "Y". It usually consists of an inlet and two outlets, where the inlet and one outlet are connected to the pipeline, and the other outlet is closed. Y-type filter is mainly used to filter solid particles, impurities and other unwanted substances in the pipeline to ensure the cleanliness of the fluid and the normal operation of the system.

[0003] The design of the Y-type filter makes the cleaning process relatively complicated and difficult. The existing Y-type filter generally needs to open the sealing cover to remove the internal filter element structure for cleaning. If the cleaning frequency is high, it is often necessary to close the corresponding connected pipeline before disassembly and cleaning, which is inconvenient and easily affects normal pipeline transportation. Therefore, we hope to design a Y-type filter with a new structure to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model aims to provide a Y-type filter that is easy to clean and solve the problems raised in the above background technology.

[0005] The utility model is realized by the following technical scheme: a Y-type filter which is easy to clean, comprising: a filter body, a filter assembly, a filter assembly is movably installed on the right side of the filter body, and the filter body comprises an inlet pipe, an outlet pipe and an installation inclined pipe;

[0006] An outlet pipe is integrally provided at the upper end of the inlet pipe, and an installation inclined pipe is integrally provided on the right side between the inlet pipe and the outlet pipe;

[0007] The filter assembly includes a docking tube, a fixed tube and a switch valve. A filter cartridge is clamped inside the docking tube. The upper end of the docking tube abuts against the lower end of the fixed tube. The lower end of the fixed tube is threadedly sealed with the upper end of the mounting inclined tube. The upper end of the fixed tube is fixed with a switch valve, and the upper end of the switch valve is installed with a drainage pipe.

[0008] As a preferred embodiment, a docking port is provided at the inner end of the inlet pipe, the inclination of the docking port is the same as the inclination of the installation inclined pipe, and the docking port is connected with the inner side of the outlet pipe through the installation inclined pipe.

[0009] As a preferred embodiment, the lower end of the docking tube is designed to be open, and a sealing ring is fixed on the edge of the lower end of the docking tube. The size of the sealing ring matches the size of the cross-section of the docking port. The docking port cooperates with the sealing ring at the lower end of the docking tube, so that all the fluid in the inlet pipe can be introduced into the filter cartridge and then enter the outlet pipe through the outlet after filtration, without some unfiltered fluid directly entering the outlet pipe through the docking port and the lower end of the docking tube, thereby ensuring the filtering effect of the entire device.

[0010] As a preferred embodiment, an outlet is opened on the upper left side of the docking tube, an annular boss is arranged inside the lower end of the docking tube, the lower end of the filter cartridge is clamped on the lower end of the docking tube through the boss, and the lower end of the filter cartridge is designed to be open.

[0011] As a preferred embodiment, the fixed tube includes a sealing head, a prism tube and a connecting tube. A ring-shaped boss 2 is arranged inside the lower end of the sealing head. The upper end of the docking tube is inserted into the upper end of the sealing head, and the upper end of the docking tube is abutted against the lower end of the boss 2. The upper end of the docking tube is open, and the upper end of the filter cartridge extends to the lower end of the sealing head.

[0012] As a preferred embodiment, four elastic rubber sheets are equally divided on the upper end of the filter cartridge, and the elastic rubber sheets are all of a fan-shaped structure. A reserved movable cavity is provided between the upper end of the filter cartridge and the inside of the sealing head. The four equally divided elastic rubber sheets enable the upper end of the filter cartridge to be in an active and open state, so that impurities in the filter cartridge can directly enter the fixed pipe under the flushing of the fluid, and then be directly discharged through the switch valve and the discharge pipe, thereby reducing the frequency of cleaning the filter cartridge due to flow interruption.

[0013] As a preferred embodiment, the upper end of the sealing head is integrally provided with a ridge tube, the upper end of the ridge tube is integrally provided with a connecting tube, and the upper end of the sealing head is connected with the ridge tube and the connecting tube.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are: by setting the filter assembly, the cleaning efficiency is greatly improved, and the operation difficulty of the user is reduced. When the filter cartridge needs to be thoroughly cleaned or replaced, the sealing head can be opened and the filter cartridge can be taken out for cleaning or replacement;

[0015] By arranging four equally divided elastic rubber sheets at the upper end of the filter cartridge, when the switch valve is not opened, the four equally divided elastic rubber sheets are subjected to less impact force, and the four equally divided elastic rubber sheets may not open or may have a smaller opening, which causes impurities located at the upper end of the filter cartridge to gather inside the upper end of the filter cartridge. When the switch valve is opened, the four equally divided elastic rubber sheets are subjected to greater impact force, and at this time the opening of the four equally divided elastic rubber sheets is larger, and the impurities located at the upper end of the filter cartridge can be discharged along with the fluid, thereby achieving the purpose of rapid impurity cleaning.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments 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.

[0025] See also Figures 1 to 5The utility model provides a technical solution: a Y-type filter that is easy to clean, comprising: a filter body 100, a filter assembly 200, the filter assembly 200 is movably installed on the right side of the filter body 100, and the filter body 100 comprises an inlet pipe 110, an outlet pipe 120 and an installation inclined pipe 130;

[0026] An outlet pipe 120 is integrally provided at the upper end of the inlet pipe 110, and an installation inclined pipe 130 is integrally provided on the right side between the inlet pipe 110 and the outlet pipe 120;

[0027] The filter assembly 200 includes a docking tube 210, a fixed tube 220 and a switch valve 230. A filter cartridge 250 is clamped inside the docking tube 210. The upper end of the docking tube 210 abuts against the lower end of the fixed tube 220. The lower end of the fixed tube 220 is threadedly sealed with the upper end of the mounting inclined tube 130. The switch valve 230 is fixed to the upper end of the fixed tube 220. The upper end of the switch valve 230 is installed with a waste pipe 240.

[0028] See also Figures 1 to 5 A docking port 111 is provided at the inner end of the inlet pipe 110 , and the inclination of the docking port 111 is the same as the inclination of the installation inclined pipe 130 . The docking port 111 is connected to the inner side of the outlet pipe 120 through the installation inclined pipe 130 .

[0029] The lower end of the docking tube 210 is designed to be open, and a sealing ring 212 is fixed on the lower edge of the docking tube 210. The size of the sealing ring 212 matches the size of the cross-section of the docking port 111. The docking port 111 cooperates with the sealing ring 212 at the lower end of the docking tube 210, so that all the fluid in the inlet pipe 110 can be introduced into the filter cartridge 250 and then enter the outlet pipe 120 through the outlet 211 after filtration, without some unfiltered fluid directly entering the outlet pipe 120 through the docking port 111 and the lower end of the docking tube 210, thereby ensuring the filtering effect of the entire device.

[0030] An outlet 211 is provided on the upper left side of the docking tube 210, and an annular boss 1 is provided inside the lower end of the docking tube 210. The lower end of the filter cartridge 250 is clamped on the lower end of the docking tube 210 through the boss 1, and the lower end of the filter cartridge 250 is designed to be open.

[0031] The fixed tube 220 includes a sealing head 221, a prism tube 222 and a connecting tube 223. An annular boss 2 is arranged inside the lower end of the sealing head 221. The upper end of the docking tube 210 is inserted into the upper end of the sealing head 221, and the upper end of the docking tube 210 abuts against the lower end of the boss 2. The upper end of the docking tube 210 is designed to be open, and the upper end of the filter cartridge 250 extends to the lower end of the sealing head 221.

[0032] As the first embodiment of the utility model, in actual use, if there are more impurities inside the upper end of the filter cartridge 250, the user can directly open the switch valve 230, and the fluid part located in the filter cartridge 250 will surge into the fixed pipe 220, thereby flushing the four elastic rubber sheets 251, and the impurities located at the upper end of the filter cartridge 250 will directly enter the fixed pipe 220 along with the fluid, and finally be discharged through the switch valve 230 and the discharge pipe 240. When there are fewer impurities in the discharged fluid, the switch valve 230 is closed. At this time, the filter cartridge 25 0 no longer enters the fixed tube 220. At this time, the four elastic rubber sheets 251 lose the impact of the fluid and merge together under the action of their own elastic recovery potential energy, thereby intercepting impurities at the upper end of the filter cartridge 250. The filter cartridge 250 can be cleaned without opening the sealing head 221 on the fixed tube 220, which greatly improves the cleaning efficiency and reduces the operating difficulty of the user. When the filter cartridge 250 needs to be thoroughly cleaned or replaced, the sealing head 221 can be opened and the filter cartridge 250 can be taken out for cleaning or replacement.

[0033] See also Figure 3 , Figure 5 Four elastic rubber sheets 251 are equally divided at the upper end of the filter cartridge 250, and the elastic rubber sheets 251 are all of a fan-shaped structure. A reserved movable cavity is provided between the upper end of the filter cartridge 250 and the inside of the sealing head 221. The four equally divided elastic rubber sheets 251 make the upper end of the filter cartridge 250 in an active and open state, so that the impurities in the filter cartridge 250 can directly enter the fixed pipe 220 under the flushing of the fluid, and then be directly discharged through the switch valve 230 and the exhaust pipe 240, thereby reducing the frequency of cleaning the filter cartridge 250 due to flow interruption.

[0034] The upper end of the sealing head 221 is integrally provided with a prism tube 222 , and the upper end of the prism tube 222 is integrally provided with a connecting tube 223 . The upper end of the sealing head 221 is in communication with the prism tube 222 and the connecting tube 223 .

[0035] As a second embodiment of the utility model, four equally divided elastic rubber sheets 251 are arranged at the upper end of the filter cartridge 250. When the switch valve 230 is not opened, the four equally divided elastic rubber sheets 251 are subjected to a smaller impact force, and the four equally divided elastic rubber sheets 251 may not open or may have a smaller opening, which causes the impurities located at the upper end of the filter cartridge 250 to gather inside the upper end of the filter cartridge 250. When the switch valve 230 is opened, the four equally divided elastic rubber sheets 251 are subjected to a larger impact force. At this time, the opening of the four equally divided elastic rubber sheets 251 is larger, and the impurities located at the upper end of the filter cartridge 250 can be discharged along with the fluid, thereby achieving the purpose of rapid impurity cleaning.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
