Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a water circulation device for a sewage treatment tank. Background Art

[0002] At present, sewage treatment tanks are a technical field used for sewage treatment. They clean and filter the impurities contained in sewage to achieve the first level of sewage purification. Generally, there are many types of sewage treatment tanks, but most of them use the addition of flocculants to combine with impurities in the water, and then filter the flocculent sediment to achieve the purpose of removing impurities in the water.

[0003] The existing sewage treatment tanks have poor ability to remove flocculent sediments, so that the discharged water still contains a portion of flocculent sediments and the filtration is not thorough. Summary of the Invention

[0004] The object of the present invention is to provide a water circulation device for a sewage treatment tank to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A water circulation device for a sewage treatment tank comprises a base, a support column is provided on the base, a tank body is fixedly connected to the support column, a motor is provided on the top of the tank body, the motor is connected to a cam via an output shaft, the cam is installed in contact with a top plate, the top plate is connected to a push rod, a first spring is provided between the push rod and the tank body, a first water hole is provided at the end of the push rod, a socket is provided in the push rod, a plug rod is installed in the socket, a second spring is provided between the plug rod and the socket, a second water hole is provided at the end of the plug rod, the first water hole and the second water hole are staggered, the push rod and the plug rod are installed in a filter cartridge, a filter layer is provided at the bottom of the filter cartridge, the bottom of the water outlet pipe is connected to the tank body, a circulation hole is provided at the bottom of the filter cartridge, an upper opening is provided at the top of the filter cartridge, the filter cartridge is fixedly connected to the tank body via a connecting rod, the upper side of the filter cartridge is connected to the water inlet pipe, a water outlet pipe is provided in the tank body, and the height of the water outlet pipe is higher than the position of the upper opening of the filter cartridge.

[0007] As a further solution of the present invention: the push rod is connected to the tank body through a bearing.

[0008] As a further solution of the present invention: both ends of the second spring are fixedly connected to the push rod and the plug rod respectively.

[0009] As a further solution of the present invention: the filter layer is fixed on the inner side of the circulation hole.

[0010] As a further solution of the present invention: grease is applied between the cam and the top plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention introduces sewage that has been precipitated with a flocculant into the filter cartridge, and with the help of a motor, a cam, and a top plate, the push rod is repeatedly pressed down, and the pressed push rod and the plug-in rod are displaced from each other, so that the first water through hole and the second water through hole are misaligned, so that the water at the lower part of the plug-in rod is squeezed out of the filter cartridge, thereby filtering the flocculent sediment. When the push rod returns to its original position and moves upward under the action of the first spring, the second spring separates the push rod and the plug-in rod from each other, and at the same time allows the sewage containing the flocculant to re-enter the filter cartridge through the first water through hole and the second water through hole for filtration again. By arranging a water outlet pipe with a height higher than the upper opening and cooperating with the circulation hole, the filtered sewage can re-enter the filter cartridge for filtration again, thereby improving the filtration effect. The above structure effectively reduces the content of flocculent sediment in the sewage. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0019] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] Example 1:

[0022] See also Figure 1-3 , a sewage treatment tank water circulation device, including a base 1, a support column 2 is provided on the base 1, a tank body 3 is fixedly connected to the support column 2, a motor 4 is provided on the top of the tank body 3, the motor 4 is connected to the cam 6 through the output shaft 5, the cam 6 is installed in contact with the top plate 7, the top plate 7 is connected to the top rod 8, a first spring 70 is provided between the top rod 8 and the tank body 3, a first water hole 100 is provided at the end of the top rod 8, a socket 9 is provided in the top rod 8, a plug rod 11 is installed in the socket 9, a second spring 90 is provided between the plug rod 11 and the socket 9, and a A second water hole 110 is provided, and the first water hole 100 and the second water hole 110 are staggered. The top rod 8 and the plug-in rod 11 are installed in the filter cartridge 10. The bottom of the filter cartridge 10 is provided with a filter layer 15. The bottom of the water outlet pipe 14 is connected to the tank body 3. The bottom of the filter cartridge 10 is provided with a circulation hole 16. The top of the filter cartridge 10 is provided with an upper opening 13. The filter cartridge 10 is fixedly connected to the tank body 3 through a connecting rod 12. The upper side of the filter cartridge 10 is connected to the water inlet pipe 101. The tank body 3 is provided with a water outlet pipe 14, and the height of the water outlet pipe 14 is higher than the position of the upper opening 13 of the filter cartridge 10.

[0023] Specifically, after adding flocculants to sewage, impurities and flocculants combine with each other to form flocculent precipitation. Clean water can be obtained by simply separating the flocculent precipitation from water.

[0024] More specifically, sewage containing flocculent sediment is introduced into the filter cartridge 10 through the water inlet pipe 101. When the push rod 8 is at the highest position, there is a gap between the first water hole 100 and the second water hole 110, and the sewage containing flocculent sediment enters the filter cartridge 10. Under the action of the rotating cam 6, the push rod 8 moves downward, and the first water hole 100 and the second water hole 110 are misaligned, so that the upper side of the filter cartridge 10 is closed. The push rod 8 drives the connecting rod 11 to continue to move downward, squeezing and filtering the sewage. The flocculent remains on the filter layer 15 of the filter cartridge 10, and the clean water leaves the filter cartridge 10 through the circulation hole 16 and reaches the tank body 3.

[0025] More specifically, when the water level inside the tank body 3 rises to the position of the upper opening 13, continuous circulation filtration of the sewage is achieved. When the water level continues to rise to the highest position of the outlet pipe 14, the circulated filtered water can leave the tank body 3 from the outlet hole 17, completing the filtration.

[0026] Furthermore, the push rod 8 is connected to the tank body 3 through a bearing.

[0027] Specifically, in order to ensure the sliding of the push rod 8 and the tank body 3, a bearing is used for connection.

[0028] Furthermore, both ends of the second spring 90 are fixedly connected to the push rod 8 and the plug rod 11 respectively.

[0029] Specifically, in order to ensure that the connecting rod 11 can move upward after being positioned upward, the push rod 8 and the connecting rod 11 are connected to each other by the second spring 90 to simplify the structure.

[0030] Furthermore, the filter layer 15 is fixed inside the circulation hole 16 .

[0031] Furthermore, grease is applied between the cam 6 and the top plate 7 .

[0032] Specifically, applying grease is to reduce the wear between the cam 6 and the top plate 7 .

[0033] Example 2:

[0034] This embodiment describes the specific working principle of a sewage treatment tank water circulation device shown in Example 1 on the basis of Example 1.

[0035] A sewage treatment tank water circulation device, such as Figure 1-3As shown, sewage containing flocculent sediment is introduced into the filter cartridge 10 through the water inlet pipe 101. When the push rod 8 is at the highest position, there is a gap between the first water hole 100 and the second water hole 110, and the sewage containing flocculent sediment enters the filter cartridge 10. Under the action of the rotating cam 6, the push rod 8 moves downward, and the first water hole 100 and the second water hole 110 are misaligned, so that the upper side of the filter cartridge 10 is closed. The push rod 8 drives the connecting rod 11 to continue to move downward, squeezing and filtering the sewage. The flocculent remains on the filter layer 15 of the filter cartridge 10, and the clean water leaves the filter cartridge 10 through the circulation hole 16 and reaches the tank body 3.

[0036] When the water level inside the tank body 3 rises to the position of the upper opening 13, continuous circulation filtration of the sewage is achieved. When the water level continues to rise to the highest position of the outlet pipe 14, the circulated filtered water can leave the tank body 3 from the outlet hole 17, completing the filtration.

[0037] It should be noted that the present invention introduces sewage that has been precipitated with a flocculant into the filter cartridge, and uses a motor, a cam, and a top plate to repeatedly press the top rod downward. The pressed top rod and the plug-in rod are displaced from each other, causing the first water hole and the second water hole to be misaligned, so that the water at the bottom of the plug-in rod is squeezed out of the filter cartridge, thereby filtering the flocculent sediment. When the top rod returns to its original position and moves upward under the action of the first spring, the second spring separates the top rod and the plug-in rod from each other, and at the same time allows the sewage containing flocculant to re-enter the filter cartridge through the first water hole and the second water hole for filtration again; by setting a water outlet pipe with a height higher than the upper opening and cooperating with the circulation hole, the filtered sewage can re-enter the filter cartridge for filtration again, thereby improving the filtration effect. The above structure effectively reduces the content of flocculent sediment in the sewage. The above is the innovation of the present invention.

[0038] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. Any reference numerals in the claims shall not be construed as limiting the claims involved.

[0039] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
