[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of a filtration mechanism for a heating pipe network, including a pipe 1 with an opening for easy removal of a filter screen 8. A support frame 2 is fixedly connected to the inner wall of the pipe 1, supporting an impeller 3. The impeller 3 is rotatably connected to the inner wall of the support frame 2. The impeller 3 is a component installed in fluid machinery such as pumps, fans, and compressors, or power machinery such as turbines and water turbines, capable of rotating and driving fluid movement or being driven to rotate by fluid to achieve energy conversion. This is prior art and will not be elaborated further. The impeller 3 is rotated by water flow, thereby achieving a cleaning effect. The support frame 2... The width is smaller than the diameter of the impeller 3, so it will not affect the propulsion of the water flow. The bottom end of the impeller 3 is fixedly connected to the fixing plate 4, and the bottom end of the fixing plate 4 is fixedly connected to the fixing column 5. The inner wall of the fixing column 5 is provided with a cleaning mechanism. The inner wall of the pipe 1 is detachably installed with a filter screen 8. The filter screen 8 can intercept impurities in the water to ensure the cleanliness of the water flow. The inner wall of the pipe 1 is provided with a disassembly component. The cleaning mechanism includes a cleaning column 7. The top end of the cleaning column 7 is elastically connected to the fixing column 5 through a movable spring 6. The cleaning column 7 is slidably connected to the inner wall of the fixing column 5. The fixing column 5 has a slot corresponding to the cleaning column 7, allowing the cleaning column 7 to move vertically.
[0034] Reference Figure 1 , Figure 4 and Figure 5 The disassembly assembly includes a handle 9, with a plug 10 inserted into the right side wall of the handle 9. The plug 10 has two sets of protrusions. The handle 9 has slots corresponding to these protrusions. Initially, the first set of protrusions is inserted into the slots of the handle 9. The right side wall of the plug 10 is elastically connected to the pipe 1 via a moving spring 11. The handle 9 is slidably connected to the inner wall of the pipe 1. The pipe 1 has slots corresponding to the handle 9, allowing the handle 9 to move vertically. The handle 9 is inserted into the top of the filter screen 8. The handle 9 has a set of... The rectangular block has a corresponding slot on the filter screen 8. The handle 9 is initially inserted into the slot. The insert 10 is slidably connected to the inner wall of the pipe 1. The pipe 1 has a corresponding slot, allowing the insert 10 to move left and right. The right side wall of the insert 10 is fixedly connected to one end of the moving spring 11, and the other end of the moving spring 11 is fixedly connected to the right inner wall of the pipe 1. When the insert 10 moves to the right, the moving spring 11 is compressed. When resetting, the elastic force of the moving spring 11 is used to reset the insert 10.
[0035] Reference Figure 1 - Figure 3The top of the cleaning column 7 is fixedly connected to one end of the movable spring 6, and the other end of the movable spring 6 is fixedly connected to the inner wall of the bottom end of the fixed column 5. When the cleaning column 7 moves upward, the movable spring 6 is compressed. When it returns to its original position, the elastic force of the movable spring 6 carries the cleaning column 7 into the filter screen 8. The movable spring 6 is initially in a compressed state, and the cleaning column 7 is inserted into the inner wall of the filter screen 8. When the cleaning column 7 is inserted into the slot of the filter screen 8, it can clean out the impurities that are blocked in the filter screen 8. The outer wall of the fixed plate 4 is in contact with the inner wall of the pipe 1. The cleaning column 7 is made of rubber material, and the bottom end of the cleaning column 7 is set as a hemispherical shape. When the slot of the filter screen 8 contacts and squeezes the bottom end of the cleaning column 7, the cleaning column 7 moves upward. The size of the cleaning column 7 is the same as the aperture of the filter screen 8.
[0036] Working principle: When water flows into pipe 1, the water flow will drive impeller 3 to rotate. Impeller 3 will rotate the fixed plate 4, fixed column 5 and cleaning column 7. When the cleaning column 7 coincides with the groove of filter screen 8, under the elastic force of movable spring 6, the cleaning column 7 will be inserted into the groove of filter screen 8. The cleaning column 7 will clean and unclog the filter screen 8. As the impeller 3 rotates, when the edge of the groove of filter screen 8 contacts and squeezes the cleaning column 7, the cleaning column 7 will move upward and compress movable spring 6. When the cleaning column 7 rotates and coincides with the groove of filter screen 8 again, the cleaning column 7 will continue to repeat the above trajectory movement.
[0037] When the filter screen 8 needs to be removed, the operator can move the insert block 10 to the right. The insert block 10 will compress the moving spring 11. When the first protrusion of the insert block 10 separates from the groove of the handle 9, the operator moves the handle 9 upward. When the rectangular block on the handle 9 separates from the groove of the filter screen 8, the second protrusion on the insert block 10 coincides with the groove of the handle 9. The operator then releases the insert block 10, and the elastic force of the moving spring 11 causes the insert block 10 to be inserted into the groove of the handle 9, thus limiting the position of the handle 9. Next, the operator can manually remove the filter screen 8. When installing the filter screen 8, the operator aligns the filter screen 8 with their hand and inserts it into the groove of the pipe 1. The operator moves the insert block 10 to the right. When the insert block 10 separates from the groove of the handle 9, the operator moves the handle 9 downwards so that the handle 9 is inserted into the groove of the filter screen 8. The operator releases the insert block 10 so that the insert block 10 is inserted into the groove of the handle 9, thus completing the positioning of the filter screen 8. When the filter screen 8 needs to be installed or removed again, the above steps can be repeated.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
