[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0025] Example 1

[0026] like Figure 1 As shown:

[0027] A scum well lifting device for a primary sedimentation tank comprises a scum well body 1 and a screening box 2 arranged inside the scum well body 1.

[0028] In this embodiment: the existing disclosure (announcement) number: CN209423030U discloses a scum well lifting device for a sewage treatment primary sedimentation tank; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the screen box can be lifted out of the scum well by pulling a rope, but during the lifting process, the scum inside the screening box 2 is easily accumulated at the bottom of the box, blocking the mesh on the screening box 2, causing too much water to accumulate inside the screening box 2, thereby increasing the power loss of the lifting device, affecting the separation effect of the scum, and being inconvenient to use". In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a vibration component 3 and a dumping component 4 are added to the application document.

[0029] More specifically:

[0030] like Figure 1-Figure 4 As shown:

[0031] In combination with the above content, the vibration assembly 3 includes a sliding rod 33 symmetrically arranged inside the slag pit body 1 and a fixed box 34 symmetrically fixedly connected to the surface of the sliding rod 33, a fixed frame plate 39 is arranged inside the fixed box 34, and the fixed frame plate 39 is hinged to the bottom of the screening box 2 through a hinge, a spring 36 is symmetrically fixedly connected between the fixed frame plate 39 and the fixed box 34, and a vibration motor 310 is fixedly connected to the surface of the fixed frame plate 39.

[0032] In this embodiment: when the scum inside the screening box 2 is lifted, the motor can pull the screening box 2 to lift it by pulling the rope, and then start the vibration motor 310 to drive the fixed frame plate 39 to vibrate inside the fixed box 34, and the spring 36 can improve the vibration effect of the fixed frame plate 39, so that the scum inside the screening box 2 oscillates, avoiding the accumulation of scum to block the mesh of the screening box 2, and the accumulated water inside the screening box 2 can be discharged through the mesh, thereby reducing the water content of the scum inside the screening box 2 and reducing the loss of the power device.

[0033] It should be noted that: due to the biochemical treatment in the primary sedimentation tank, the scum produced will be mixed with a large amount of toxic gases such as methane, which can easily cause workers to be poisoned and unconscious, posing a serious safety hazard. By driving the screening box 2 to lift inside the scum well body 1 and flip the scum toward the outside of the scum well, the workload of the workers is greatly reduced. There is no need to go down the well, and gas poisoning when people go down the well is avoided.

[0034] Going further:

[0035] like Figure 1-Figure 4 As shown:

[0036] In order to improve the stability of the movement of the fixed box 34, in an optional embodiment: both ends of the slide rod 33 are T-shaped structures, and a sliding groove matching the slide rod 33 is provided on the side of the slag pit body 1 close to the slide rod 33; a baffle 37 is fixedly connected to the surface of the fixed frame plate 39 close to the fixed box 34, and a sealing groove 38 is provided on the side of the fixed box 34 close to the baffle 37;

[0037] In this embodiment: when the pull rope moves the fixed box 34, it can drive the slide rod 33 to slide in the sliding groove inside the slag pit body 1, thereby improving the stability of the movement of the fixed box 34. During the vibration of the fixed frame plate 39, it can drive the baffle plate 37 to slide inside the sealing groove 38, and the movable groove of the fixed frame plate 39 of the baffle plate 37 is blocked to prevent sewage from seeping through the fixed frame plate 39 and the fixed box 34.

[0038] Going further:

[0039] like Figure 1-Figure 4 As shown:

[0040] In order to facilitate pulling the screening box 2 for lifting, in an optional embodiment: a plurality of cleaning plates 35 are fixedly connected to the top of the side of the screening box 2; a fixing rod 32 is symmetrically fixedly connected to the upper surface of the fixing box 34, and a pull ring 31 is fixedly connected to the top of the fixing rod 32.

[0041] In this embodiment: when it is necessary to lift the scum in the screening box 2, the fixing box 34 is connected to the pull rope through the pull ring 31, and then the pull rope is pulled by the motor to pull the screening box 2 to lift, and the scum on the inner wall of the scum pit body 1 can be cleaned and scraped off through the cleaning plate 35.

[0042] More specifically:

[0043] like Figure 1-Figure 4 As shown:

[0044] In combination with the above content, a dumping assembly 4 is provided on the surface of the fixed frame plate 39, and the dumping assembly 4 includes a support plate 42 fixedly connected to the surface of the fixed frame plate 39 close to the side of the screening box 2 and an electric push rod 41 hinged between the screening box 2 and the support plate 42 through a hinge seat.

[0045] In this embodiment: after the screening box 2 is lifted to the upper side of the slag pit body 1, the screening box 2 can be pushed to flip along the hinge by starting the electric push rod 41, so as to facilitate the dumping and discharge of the slag on the inner wall of the screening box 2, and the support plate 42 can support and limit the screening box 2 placed on the fixed frame plate 39.

[0046] It should be noted that the electric push rod 41 and the vibration motor 310 are both electrically connected to an external power source through a wire, and the electric push rod 41 is waterproof.

[0047] Working principle: When the primary sedimentation tank scum well lifting device is in use, it is connected to the pull rope through the pull ring 31, and then the pull rope is pulled by the motor to pull the screening box 2 to lift it, and then the vibration motor 310 is started to drive the fixed frame plate 39 to vibrate inside the fixed box 34, and the spring 36 can improve the vibration effect of the fixed frame plate 39. The vibration of the fixed frame plate 39 can drive the baffle plate 37 to slide inside the sealing groove 38, and the movable groove of the fixed frame plate 39 of the baffle plate 37 is blocked to prevent sewage from infiltrating through the fixed frame plate 39 and the fixed box 34. At the same time, the fixed frame plate 39 will drive the scum inside the screening box 2 to vibrate to prevent scum accumulation. The mesh holes of the screening box 2 are blocked so that the accumulated water inside the screening box 2 can be discharged through the mesh holes, thereby reducing the water content of the scum inside the screening box 2 and alleviating the loss of the power device. During this period, the slide bar 33 slides in the sliding groove inside the scum pit body 1 to improve the stability of the movement of the fixed box 34. At the same time, the scum on the inner wall of the scum pit body 1 can be cleaned and scraped off by the cleaning plate 35. After the screening box 2 is lifted to the upper side of the scum pit body 1, the screening box 2 can be pushed to flip along the hinge by starting the electric push rod 41, which is convenient for dumping and discharging the scum on the inner wall of the screening box 2, and the support plate 42 can support and limit the screening box 2 placed on the fixed frame plate 39.

[0048] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention to solve the problems raised in the above background technology.
