Based on the embodiments in 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.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment of a quick-detachable filter, including a filter barrel 1, which is an existing nylon liquid filter bag installation and use device. The prior art is not described in detail here. The top of the filter barrel 1 is fixedly connected with a fixing block 2, and the inner wall of the right end of the fixing block 2 is elastically connected to a limiting plate 4 through a reset spring 3. The limiting plate 4 is an inclined surface. When squeezed, the limiting plate 4 will slide along the inner wall of the fixing block 2. The outer wall of the limiting plate 4 is provided with a positioning mechanism. The top of the filter barrel 1 contacts with a round cover 6, and the outer wall of the round cover 6 is fixedly connected with a connecting block 7. The inner side wall of the connecting block 7 is provided with a limiting groove 8. The interior of the filter barrel 1 is provided with a mesh cylinder 9, and the mesh cylinder 9 and the nylon liquid filter bag can be installed, so that the nylon liquid filter bag can be fitted on the inner wall of the mesh cylinder 9 for use.

[0031] Reference Figure 1 and Figure 4The top inner wall of the filter barrel 1 is elastically connected with a movable disk 11 through a positioning spring 10. The movable disk 11 mainly plays the role of supporting and connecting the circular ring 12 and the net cylinder 9. The top of the movable disk 11 is fixedly connected with a circular ring 12. The middle part of the circular ring 12 is hollow, so that the middle part of the circular ring 12 can be plugged with the net cylinder 9 to position the net cylinder 9. The inner wall of the circular ring 12 is plugged with the net cylinder 9. The inner wall of the bottom end of the round cover 6 is fixedly connected with a pressing ring 13. The top of the net cylinder 9 matches the corner of the nylon liquid filter bag. The top contact corner of the nylon liquid filter bag is compacted and fixed with the net cylinder 9 by the pressing ring 13 to ensure that the net cylinder 9 and the nylon liquid filter bag will not separate. The bottom end of the pressing ring 13 is provided with a telescopic rod 14. The telescopic rod 14 is an existing three-section telescopic rod 14, and the three-section telescopic rod 14 is connected to an external device. The bottom end of the telescopic rod 14 can be moved downward with the extrusion plate 15 by an electric method. The movable end of the telescopic rod 14 is fixedly connected with an extrusion plate 15. The outer wall of the filter barrel 1 is slidably connected with a bracket 16, and the bracket 16 mainly supports and connects the entire filter barrel 1. The inner side wall of the bracket 16 is fixedly connected with a support plate 18, and the top of the support plate 18 is fixedly connected with an electric push rod 17. The electric push rod 17 is a device for pushing an object to move by electric drive, which can make the filter barrel 1 move vertically to a certain use height. It is a prior art that will not be described in detail here. The inner wall of the top of the filter barrel 1 is fixedly connected with one end of the positioning spring 10. When the movable disk 11 moves downward, the positioning spring 10 is compressed. When resetting, the elastic force of the positioning spring 10 is used to reset the movable disk 11. The other end of the positioning spring 10 is fixedly connected to the bottom end of the movable disk 11, and the movable disk 11 is slidably connected to the inner wall of the filter barrel 1, and the bottom end of the pressure ring 13 contacts the top of the mesh barrel 9.

[0032] Reference Figure 1-Figure 3 The inner wall of the right end of the fixed block 2 is fixedly connected to one end of the return spring 3. When the limit plate 4 moves to the right, the return spring 3 will be compressed. When resetting, the limit plate 4 is reset with the elastic force of the return spring 3. The other end of the return spring 3 is fixedly connected to the right end of the limit plate 4. The limit plate 4 is slidably connected to the inner wall of the fixed block 2. The limit plate 4 is plugged into the inner wall of the limit groove 8. The positioning mechanism includes a moving block 5, which is slidably connected to the outer wall of the limit plate 4. The limit plate 4 is provided with The slot allows the movable block 5 to move vertically along the limit plate 4. The movable block 5 is engaged with the inner wall of the fixed block 2. The fixed block 2 is provided with an L-slot, which allows the movable block 5 to slide in the L-slot. The L-slot has a horizontal opening and a vertical opening. Since the inclined length of the limit plate 4 is certain, the limit plate 4 will slide along the L-slot with the movable block 5, and the movable block 5 will not overlap with the vertical opening of the L-slot. It is necessary to manually move the movable block 5 to the vertical opening of the L-slot, and the fixed block 2 is plugged into the inner wall of the connecting block 7.

[0033] Working principle: First, when installing the round cover 6 and the filter barrel 1, install the mesh tube 9 and the nylon liquid filter bag first, plug the mesh tube 9 and the ring 12, and then splice the round cover 6 with the top of the filter barrel 1, plug the connecting block 7 and the fixed block 2, and use the bottom end of the connecting block 7 to squeeze the inclined surface of the limit plate 4, so that the limit plate 4 moves the moving block 5 to the right and compresses the reset spring 3. When the limit groove 8 coincides with the limit plate 4, use the reverse elastic force of the reset spring 3 to reset the limit plate 4, and plug the limit plate 4 and the limit groove 8 to install the entire round cover 6 in one direction. The operation is simple and convenient.

[0034] When the round cover 6 is installed, the pressure ring 13 will squeeze the top of the mesh tube 9 and compress the positioning spring 10, so that the movable disk 11, the ring 12 and the mesh tube 9 move downward into the filter barrel 1, and the squeezing plate 15 enters the inner wall of the mesh tube 9. The telescopic rod 14 is telescoped through the electronic control device to move the squeezing plate 15 downward to press the nylon liquid filter bag to fit the inner wall of the mesh tube 9. There is no need to manually adjust the nylon liquid filter bag. During use, the device can control the telescopic rod 14 to telescope and move the squeezing plate 15 vertically, so that the liquid in the nylon liquid filter bag is squeezed and quickly filtered.

[0035] When the nylon liquid filter bag on the mesh cylinder 9 needs to be taken out for cleaning, it is only necessary to move the movable block 5 with the limit plate 4 to the right to separate the limit plate 4 and the notch of the limit groove 8. When the movable block 5 and the L groove of the fixed block 2 are vertically overlapped, the movable block 5 is moved downward to make the movable block 5 stuck in the vertical opening of the L groove to ensure that the limit plate 4 continues to be exposed in the fixed block 2 and will not be blocked by disassembly. Subsequently, the round cover 6 and the top of the filter barrel 1 are separated. When installing again, the movable block 5 is separated from the vertical opening of the L groove of the fixed block 2 to allow the limit plate 4 to return to the initial state with the movable block 5. Since the pressure ring 13 no longer squeezes the mesh cylinder 9, the reverse elastic force of the positioning spring 10 will be used to push the movable disk 11, the circular ring 12 and the mesh cylinder 9 upward, so that the staff can replace and clean the nylon liquid filter bag in the mesh cylinder 9.

[0036] Before the whole device is used, the electric push rod 17 can be driven by an external device to drive the filter barrel 1 to rise or fall to a certain height. The height of the filter barrel 1 can be adjusted according to the actual height conditions of the staff, so that the staff can operate the whole filter conveniently.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
