[0030] 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.
[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0032] Please see Figure 1 - Figure 7 As shown, this utility model is a simple water purification device for slimming fish farming, including a purification cylinder 1 and two filter tubes 4, which are symmetrically arranged inside the purification cylinder 1. A rotating plate 2 is rotatably installed inside the purification cylinder 1 and fits against the inner wall of the purification cylinder 1. A filter element 401 is fixed inside the filter tube 4. The upper end and the left side of the lower end of the purification cylinder 1 are connected to the water inlet pipe 18 and the water outlet pipe 19, respectively. The rotation of the rotating plate 2 drives the two filter tubes 4 to change position. A locking seat 5 is fixedly connected to the upper end of the outer wall of the rotating plate 2. The locking seat 5 has a locking groove 501 that is inserted into the locking block 7. The upper outer wall of the filter tube 4 is fixedly connected to the connecting sleeve 6. The top surface of the connecting sleeve 6 is slidably installed with the sliding plate 10 inside. A smooth plate 8 that penetrates the side wall of the fixed shell 9 is fixed between the locking block 7 and the sliding plate 10. The movement of the sliding plate 10 drives the locking block 7 to separate from the locking groove 501 through the smooth plate 8.
[0033] This embodiment provides a simple water purification device for raising slimmer fish. The rotating plate 2 can divide the space inside the purification cylinder 1 into two areas. The inlet pipe 18 and the outlet pipe 19 are equipped with connecting flanges. Water enters the purification cylinder 1 through the inlet pipe 18 and is filtered through the filter pipe 4 on the left. When the filter pipe 4 needs to be cleaned or replaced, rotating the rotating plate 2 will cause the two filter pipes 4 to switch positions without turning off the purification device. The filter pipe 4 is fixed to the rotating plate 2 by inserting the locking block 7 and the locking groove 501 above the connecting sleeve 6. By pulling the sliding plate 10, the smooth plate 8 and the locking block 7 can be moved laterally, so that the locking block 7 is separated from the locking groove 501, realizing the quick unlocking of the filter pipe 4 and making it easy to remove the filter pipe 4.
[0034] The rotating plate 2 has a limiting sleeve 3 fixed on both sides, which fits against the outer wall of the purification cylinder 1. The filter tube 4 passes through the limiting groove 301 opened in the limiting sleeve 3. The limiting groove 301 is fixedly connected to the sealing ring 302, and the sealing ring 302 is interference-fitted with the outer wall of the filter tube 4. When the filter tube 4 is installed, it is automatically positioned by the cooperation between the limiting groove 301 and the filter tube 4. The sealing ring 302 seals the filter tube 4 and the limiting sleeve 3. The sealing ring 302 is made of silicone.
[0035] The rotating plate 2 has a rotating shaft 202 fixed at its top. The rotating shaft 202 passes through the bottom surface of the top plate of the purification cylinder 1 and is rotatably connected to the purification cylinder 1. The bottom of the purification cylinder 1 has a motor 20 whose output end is fixed to the bottom end of the rotating plate 2. The motor 20 drives the rotating plate 2 to rotate, so that the two filter tubes 4 are swapped.
[0036] The sliding plate 10 is provided with a smooth rod 11 that penetrates the side wall of the fixed shell 9 on the side away from the smooth plate 8. The smooth rod 11 is fixedly connected to the actuating plate 12. By pulling the actuating plate 12, the sliding plate 10 can be moved laterally through the smooth rod 11.
[0037] The top surface of the locking seat 5 and the bottom surface of the locking block 7 are both provided with inclined guide surfaces. A spring is fixed between the inner wall of the fixed shell 9 and the sliding plate 10, and the spring is wound around the smooth rod 11. When the filter tube 4 is installed, the filter tube 4 is sleeved together with the limiting sleeve 3. The downward movement of the filter tube 4 will drive the locking block 7 to move downward. The locking block 7 and the guide surface of the locking seat 5 come into contact, pushing the locking block 7 to move laterally. After the locking block 7 is aligned with the locking groove 501, the spring drives the locking block 7 to insert into the locking groove 501, thereby fixing the filter tube 4 and the rotating plate 2.
[0038] The purification cylinder 1 has a retrieval port 101 on the right side of its top end that mates with a cover plate 13. Both sides of the cover plate 13 are rotatably connected to a connecting seat 103, which is fixedly connected to the purification cylinder 1. The upper end of the outer wall of the purification cylinder 1 is fixedly connected to a fixing seat 102 with an insertion slot 1021. The insertion slot 1021 is inserted into an insertion block 15. A connecting plate 1501, rotatably connected to a screw 16, is fixedly mounted on one side of the insertion block 15. The screw 16 is threadedly connected to a vertical plate 14, and the top end of the vertical plate 14 is connected to one side of the cover plate 13 via a connecting block 1401. The screw 16 is fixedly connected to the connecting plate 1501 and the vertical plate 14 at both ends. One end of the screw 16 is provided with a knob. By rotating the knob, the screw 16 is rotated, which in turn drives the plug block 15 to move laterally and separate from the plug slot 1021 through the connecting plate 1501. Then the cover plate 13 can be opened to take out the filter tube 4 on the right side. The telescopic rod 17 guides the movement of the plug block 15 and the connecting plate 1501 to ensure that the connecting plate 1501 and the plug block 15 can move laterally smoothly.
[0039] The connecting sleeve 6 has an avoidance groove 601 on one side, which avoids the locking seat 5 and prevents the locking seat 5 from colliding with the connecting sleeve 6 when the filter tube 4 is placed into the limiting sleeve 3.
[0040] The outer wall of the rotating plate 2 is fixed with two sealing rings 201, and the sealing rings 201 are interference fit with the inner wall of the purification cylinder 1. The sealing rings 201 seal the purification cylinder 1 and the rotating plate 2. The sealing rings 201 are made of silicone.
[0041] The bottom right side of the purification cylinder 1 is connected to the drain pipe 21 with a valve installed on the outer wall. When the filter tube 4 is taken out, impurities may fall off. After opening the cover plate 13 and taking out the filter tube 4, the space on the right side of the purification cylinder 1 can be cleaned with a water pipe or a brush. The sewage can be discharged directly by opening the valve of the drain pipe 21.
[0042] It is understandable that the filter tube 4 can be replaced without stopping the machine, and the filter tube 4 can be quickly disassembled.
[0043] A specific application of the operation process of this embodiment is as follows: water flows in from the inlet pipe 18, is purified by the filter element 401 in the left filter pipe 4, and is discharged from the drain pipe 19. When it is necessary to clean or replace the left filter pipe 4, the rotating plate 2 is rotated 180° by the motor 20, so that the two filter pipes 4 are swapped and the filter pipe 4 that needs to be cleaned or replaced is moved to the right side.
[0044] Then, by rotating the screw 16 through the knob, the plug block 15 is separated from the plug slot 1021. The cover plate 13 is lifted, and the locking block 7 is disengaged from the locking slot 501 by the actuating plate 12, thus releasing the lock of the filter tube 4. Then, the filter tube 4 is taken out from the purification cylinder 1 and cleaned or replaced.
[0045] When installing the filter tube 4, insert the lower end of the filter tube 4 into the limiting sleeve 3 and apply a downward force to the limiting sleeve 3. The filter tube 4 drives the locking block 7 to move down. The locking block 7 and the guide surface of the locking seat 5 come into contact, pushing the locking block 7 to move laterally. After the locking block 7 is aligned with the locking groove 501, the spring drives the locking block 7 to insert into the locking groove 501, thereby fixing the filter tube 4 and the rotating plate 2. Then, cover the cover plate 13 and rotate the screw 16 by turning the knob to insert the plug 15 into the plug groove 1021.
