[0029] To better understand the purpose, structure, and function of this utility model, a continuous activated sand filter device of this utility model will be described in further detail below with reference to the accompanying drawings.
[0030] like Figure 1-6As shown, this utility model discloses a continuous activated sand filter device, including a filter device body 1, a fixing frame 5 mounted on the surface of the filter device body 1, a collar 6 welded to one end of the fixing frame 5, a sleeve 9 fitted onto the surface of the collar 6, and a first fixing block 8 fixedly connected to the surface of the sleeve 9. By installing the sleeve 9 and the collar 6, a ladder 7 can be moved using the sleeve 9 and the collar 6, allowing the ladder 7 to be moved to a position convenient for maintenance. This allows the ladder 7 to be adjusted as needed, making it very convenient to use. The ladder 7 is welded to the first fixing block 8, and an internal threaded sleeve 10 is welded to the surface of the sleeve 9. A screw rod 11 is fitted inside the internal threaded sleeve 10, a rotating plate 12 is welded to one end of the screw rod 11, and the other end of the screw rod 11 is attached to the surface of the collar 6. By installing the screw rod 11, when the ladder 7 moves to a suitable position, the screw rod 11 can be rotated, and under the action of the internal threaded sleeve 10, the screw rod 11 can be pressed against the collar 6, thereby providing a fixed position for the ladder 7, resulting in strong stability during use.
[0031] Support legs 16 are welded to the surface of the filter device body 1, and a frame 17 is welded to the surface of the support legs 16. A groove 19 is opened on the surface of the frame 17, and a base plate 18 is provided inside the frame 17. A second external threaded rod 20 is welded to the top of the base plate 18. The second external threaded rod 20 is located inside the groove 19, and a pressing turntable 21 is sleeved on the surface of the second external threaded rod 20. One end of the pressing turntable 21 is attached to the surface of the frame 17. By installing the base plate 18, the contact area between the device and the ground can be expanded, thereby increasing the friction between the device and the ground and thus improving the stability of the device after placement.
[0032] A support block 2 is welded to the surface of the filter device body 1. A first external threaded rod 3 is welded to the top of the support block 2. The first external threaded rod 3 passes through the fixing frame 5. A nut 4 is sleeved on the surface of the first external threaded rod 3. One end of the nut 4 is attached to the surface of the fixing frame 5. By installing the first external threaded rod 3, when the ladder 7 needs to be used, the fixing frame 5 can be installed on the support block 2. When installing the fixing frame 5, the first external threaded rod 3 can pass through the fixing frame 5. Then, the nut 4 is sleeved on the surface of the first external threaded rod 3 until one end of the nut 4 is attached to the surface of the fixing frame 5. This provides the ladder 7 with the effect of being able to be installed and removed.
[0033] The collars 6 are symmetrically distributed. A second fixing block 13 is welded to the surface of the ladder 7. A limiting sleeve 14 is fixedly connected to the surface of the second fixing block 13. The collars 6 are sleeved inside the limiting sleeve 14. By installing the limiting sleeve 14, the limiting sleeve 14 can provide a limiting effect for the ladder 7, so that the ladder 7 will not easily detach from the collars 6, thus improving the stability of the ladder 7 during use.
[0034] A groove 22 is provided at the bottom of the base plate 18, and an anti-slip pad 23 is glued to the bottom of the base plate 18. The anti-slip pad 23 is located inside the groove 22. By installing the anti-slip pad 23, the friction between the base plate 18 and the ground can be increased, thereby further improving the stability of the device after it is placed.
[0035] The base plate 18 is symmetrically distributed. The other end of the second external thread rod 20 is welded with a ball head 24. The surface of the support leg 16 is welded with a reinforcing strip 15. By installing the ball head 24, when it is necessary to move the base plate 18, the ball head 24 can be used as the force point. The base plate 18 can be moved directly through the ball head 24, which is very convenient to use.
[0036] The working principle of this continuous activated sand filter is as follows: When using this device, the fixed frame 5 should first be installed on the support block 2. At this time, the first external threaded rod 3 passes through the fixed frame 5, and then the nut 4 is sleeved on the surface of the first external threaded rod 3 until one end of the nut 4 is attached to the surface of the fixed frame 5. Then, the bottom plate 18 is moved to a suitable position. At this time, the support leg 16 is welded to the surface of the filter body 1, and the frame 17 is welded to the surface of the support leg 16. At the same time, the sliding groove 19 is opened on the surface of the frame 17, and the bottom plate 18 is provided inside the frame 17. A second external threaded rod 20 is welded to the top of plate 18. At this time, the second external threaded rod 20 is located inside the slide groove 19, and a pressing turntable 21 is sleeved on the surface of the second external threaded rod 20. One end of the pressing turntable 21 is attached to the surface of the frame 17. After the device is placed in a suitable position, the base plate 18 can be moved through the slide groove 19 until the base plate 18 is moved to its outermost position. Then, the pressing turntable 21 is rotated to increase the friction between the base plate 18 and the frame 17, thereby providing a fixing effect for the base plate 18. The base plate 18 can be expanded... The increased contact area between the device and the ground improves the friction between them, thus enhancing the stability of the device after placement. The device can then be used. When maintenance is required during use, a mounting bracket 5 is installed on the surface of the filter body 1, with a collar 6 welded to one end. A sleeve 9 is fitted onto the collar 6, and a first fixing block 8 is fixedly connected to the sleeve 9. A ladder 7 is welded to the first fixing block 8, and an internally threaded sleeve 10 is welded to the sleeve 9. A threaded rod 11 is connected to the sleeve, and a turntable is welded to one end of the threaded rod 11. At this time, the other end of the threaded rod 11 is attached to the surface of the collar 6. When the ladder 7 is far from the position to be repaired during the maintenance of the device, the ladder 7 can be moved by the sleeve 9 and the collar 6 until the ladder 7 is in a convenient position for maintenance. Then, by rotating the threaded rod 11, the threaded rod 11 can be squeezed by the internal threaded sleeve 10, thereby providing a fixed position for the ladder 7. At this time, the position of the ladder 7 can be adjusted as needed, which is very convenient to use.
