Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a scum skimming device for a sewage treatment plant. Background Art

[0002] In the pretreatment stage of the sewage treatment plant, a large amount of scum will be generated. The scum often gathers and becomes compacted. The original skimmer pushes the scum into the skimmer by the force of the water flow, but the water flow force is small, which makes it difficult for the scum to flow with the water, thus gathering and compacting. Manual auxiliary skimming is required. Manual skimming is laborious and laborious, and the workload is huge. In order to improve the scum treatment efficiency of sewage, a scum skimming device is needed, but the existing scum skimming device still has the following shortcomings:

[0003] For example, the utility model with application number 202321865438.7 discloses a scum skimming device for a sewage treatment plant. The utility model sets a flow-pushing mechanism in the water to ensure that the pushing blade will not leave any residue during the operation, and the time exposed to the air is short, so that the residual foam and scum will not be hardened; at the same time, a swinging jet mechanism is set to spray to the water surface, thereby enhancing the flow of the water surface and ensuring that the scum can continuously move toward the second overflow port; at the same time, two overflow ports are set in the original water pool, which is more conducive to discharging scum. However, similar to the comparative documents of the above-mentioned application, when the existing scum skimming device is used, since most of the skimming devices are not easy to adjust the equipment use height according to the depth of the sewage, the scum treatment effect is poor and requires manual assistance and is time-consuming and labor-intensive, resulting in the problem of reduced practicality and reduced use efficiency of the scum skimming device.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a scum skimming device for sewage treatment plants is proposed. Utility Model Content

[0005] The utility model aims to provide a scum skimming device for a sewage treatment plant to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a scum skimming device for a sewage treatment plant, comprising a raw water tank and a cleaning component, overflow ports are provided at both ends above the raw water tank, a cleaning component is provided on the inner side of the raw water tank, and the cleaning component comprises a pneumatic telescopic rod, a mounting seat, a servo motor, a flow-pushing plate, a filter screen and a receiving bucket, a mounting seat is installed at the front end of the pneumatic telescopic rod, a servo motor is provided outside the mounting seat, and a flow-pushing plate is connected to the front end of the servo motor, and a filter screen is installed at the lower end of the flow-pushing plate, a receiving bucket is additionally provided at the lower end of the filter screen, and moving components are provided on both sides of the upper end of the raw water tank.

[0007] Furthermore, the pneumatic telescopic rod and the mounting seat are distributed vertically, and the pneumatic telescopic rod and the mounting seat are threadedly connected.

[0008] Furthermore, the mounting seat is in a "T" shape, and the mounting seat is symmetrically arranged on both sides of the original water pool.

[0009] Furthermore, the outer side of the flow-pushing plate is flush with the inner side of the raw water pool, and the flow-pushing plate is rotationally connected to the raw water pool via a servo motor.

[0010] Furthermore, the moving assembly includes a limit frame, a limit slot and a driving motor. The limit slot is provided on the inner side of the limit frame, and the driving motor is installed at one end of the limit frame.

[0011] Furthermore, the moving component also includes a rotating shaft, a screw rod and a movable slider, and the front end of the driving motor is connected to the rotating shaft, and the front end of the rotating shaft is connected to the screw rod, and the movable slider is connected to the outside of the screw rod.

[0012] Furthermore, the inner dimensions of the limiting through slot match the outer dimensions of the movable slider, and the movable slider is embeddedly connected to the limiting frame via the limiting through slot.

[0013] Furthermore, the movable slider is embedded in the limiting frame, and the movable slider is slidably connected to the limiting frame via a screw rod.

[0014] The utility model provides a scum skimming device for a sewage treatment plant, which has the following beneficial effects:

[0015] 1. The utility model can use the cleaning component to avoid the problem that most skimming devices are difficult to adjust the height of the equipment according to the depth of sewage when using the scum skimming device in the sewage treatment plant, which results in poor scum treatment effect and requires manual assistance and is time-consuming and labor-intensive, resulting in the problem that the practicability of the scum skimming device is reduced. The pneumatic telescopic rod is fixedly installed at the lower end of the movable slider by using the fastening bolts, and the mounting seat is fixedly installed at the front end of the pneumatic telescopic rod with the fastening bolts. The pneumatic telescopic rod operation drives the mounting seat to move the position, thereby adjusting the overall use height of the push flow plate, and the servo motor is fixedly installed on the outside of the mounting seat. The output shaft of the servo motor is connected to the push flow plate through a coupling. The servo motor operation drives the push flow plate to rotate and adjust, and the push flow plate is used to clean the scum on the water surface, and the filter net is used to intercept the excess scum at the same time. When the push flow plate is rotated for cleaning, the receiving bucket is used to avoid the backflow of the scum, thereby improving the activity of the skimming device during use.

[0016] 2. The utility model can avoid the inconvenience of most skimming devices to move the push flow plate by themselves through the setting of the moving component when the scum skimming device is used in the sewage treatment plant through the moving component set at the upper end of the raw water tank, so that the resistance of the water flow affects the skimming effect, resulting in the situation that the use efficiency of the skimming device is reduced. The limit frame is fixedly installed on both sides of the upper end of the raw water tank through fasteners, and the driving motor is fixedly installed on one side of the limit frame with the fasteners. The output shaft of the driving motor is connected to the rotating shaft through a coupling. The driving motor drives the rotating shaft to rotate so that the screw rod connected to the front end of the rotating shaft rotates inside the limit frame, and then drives the movable slider connected to the outside of the screw rod to rotate inside the limit frame. The internal size of the limiting groove opened on the inner side of the limit frame matches the external size of the movable slider, and then the limiting groove cooperates with the screw rod to make the movable slider slide left and right inside the limit frame, so that the movement of the movable slider drives the push flow plate to move, and then the sewage is skimmed, and the use efficiency of the skimming device is further improved.
