Description

Technical Field

[0001] The present invention relates to the technical field of silt clearing devices, in particular to a silt clearing device for a domestic sewage pool. Background Art

[0002] In modern industrial production, power plants, as an important component of energy supply, generate large amounts of domestic sewage during operation. This sewage is typically collected in dedicated domestic sewage pools for treatment. However, over time, a large amount of silt and solid waste accumulates at the bottom of the sewage pool. These sediments not only occupy the effective volume but can also lead to problems such as poor sewage discharge, equipment corrosion, and environmental pollution. Conventional dredging methods involve draining the sewage pool and manually clearing the silt from the bottom, or mechanically using a suction pump. However, manual cleaning is time-consuming and costly, while mechanical suction makes it difficult to observe the pool bottom, making it difficult to completely remove the silt.

[0003] In view of this, the present invention is designed to solve the above problems.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned shortcomings and provide a domestic sewage pool desilting device.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A domestic sewage pool silt removal device comprises a sewage pool body, wherein a silt accumulation pool connected to the silt accumulation pool is provided at the side end of the sewage pool body, and a flap mechanism for opening and closing the silt discharge port is provided between the sewage pool body and the silt accumulation pool; gear ring tracks are provided on both sides of the inner wall of the sewage pool body, a drive chassis is provided in the sewage pool body, and submersible motors are provided on both sides of the drive chassis. The submersible motor is engaged with the gear ring track through the traveling gear installed at the upper end thereof, so that when the submersible motor drives the traveling gear to rotate, the drive chassis circulates on the gear ring track; a silt sweeping plate for sweeping the silt at the bottom of the pool is provided at the lower part of the drive chassis, and a trigger component is provided on the silt sweeping plate so that the silt sweeping plate can be triggered to open when it moves to the flap mechanism.

[0008] Furthermore, a limiting roller is provided on the side of the traveling gear away from the submersible motor, and the side wall of the sewage tank body is also provided with an outer ring track and an inner rail plate located inside the outer ring track. A limiting ring groove for the limiting roller to limit the movement is provided on the side of the outer ring track opposite to the inner rail plate.

[0009] Further, first limiting chutes are formed on two side walls of the sewage tank body perpendicular to the moving direction of the driving machine box. An ear plate is arranged on the driving machine box, and a limiting rod whose two ends are movably inserted through the ear plate and are limited to move up and down in the first limiting chutes is arranged on the ear plate.

[0010] Further, the movable plate mechanism includes a sealing plate assembly for movably closing the silt discharge opening and a limiting assembly for limiting the moving track of the sealing plate assembly.

[0011] Further, the sealing plate assembly includes a vertical sealing plate and a horizontal sealing plate that are mutually combined into a T shape, and connecting rods whose two ends are respectively hinged to the outer surfaces of the two.

[0012] Further, second limiting chutes for limiting the sliding of two ends of the vertical sealing plate are formed on the inner wall of the sewage tank body. The limiting assembly includes a supporting fixed rod fixedly arranged on the bottom wall of the sewage tank body, a lower suspension track arranged on the lower surface of the horizontal sealing plate, a movable connecting piece whose one end is hinged to the supporting fixed rod and the other end is clamped and limited to slide in the lower suspension track, and a first spring whose one end is arranged on the bottom wall of the sewage tank body and the other end is arranged on the lower surface of the horizontal sealing plate.

[0013] Further, the triggering assembly includes a fixed arm rod arranged on the horizontal sealing plate, a horizontal connecting shaft roller arranged between the fixed arm rods, and a lifting and pulling plate arranged on the silt sweeping plate for lifting the horizontal connecting shaft roller.

[0014] Further, a movable opening is formed on the silt sweeping plate. Third limiting chutes are formed on two sides of the movable opening. Limiting sliders that are limited to slide in the third limiting chutes are arranged on two sides of the lifting and pulling plate. A fixed plate is further arranged on the surface of the silt sweeping plate. A second spring is arranged between the lifting and pulling plate and the fixed plate.

[0015] Further, a mud blocking plate for covering the movable opening is arranged on the lower surface of the lifting and pulling plate.

[0016] Compared with the prior art, the beneficial effects of this solution are as follows: By arranging a silt sweeping plate for pushing and sweeping silt in the sewage tank body and limiting it to circularly move on the toothed ring track through the walking gears on both sides, the silt sweeping plate can unidirectionally and circularly push and sweep the silt at the bottom of the sewage tank body and collect all of it into the silt accumulation pool for centralized cleaning, achieving the effect of separating water from silt, reducing labor costs, and at the same time avoiding the problem of incomplete suction by the suction pump.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in combination with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1-5The shown domestic sewage tank silt cleaning device includes a sewage tank body 1. A silt accumulation tank 11 communicated with the sewage tank body 1 is arranged at the side end of the sewage tank body 1. A flap mechanism for opening and closing a silt discharge port 12 is arranged between the sewage tank body 1 and the silt accumulation tank 11. Tooth ring tracks 2 are arranged on both sides of the inner wall of the sewage tank body 1. A driving machine box 21 is arranged inside the sewage tank body 1. Submersible motors 22 are arranged on both sides of the driving machine box 21. The submersible motors 22 are in meshing transmission with the tooth ring tracks 2 through walking gears 23 installed at their upper ends. When the submersible motors 22 drive the walking gears 23 to rotate, the driving machine box 21 makes a cyclic walk on the tooth ring tracks 2. A silt sweeping plate 24 for pushing and sweeping the silt at the bottom of the tank is arranged at the lower part of the driving machine box 21. A triggering component is arranged on the silt sweeping plate 24, so that the silt sweeping plate 24 can trigger the opening of the flap mechanism when it moves to the flap mechanism. When the device is running, the walking gears 23 are driven to rotate by the submersible motors 22 on both sides. The walking gears 23 are in meshing with the tooth ring tracks 2, and then make a cyclic movement inside the tooth ring tracks 2, thereby driving the silt sweeping plate 24 at the bottom of the driving machine box 21 to make a lateral movement at the bottom of the sewage tank body 1, and then pushing and sweeping the silt to the flap mechanism. When the silt is pushed and swept back to the flap mechanism, the flap mechanism is triggered to open by the triggering component on the silt sweeping plate 24, and then the silt enters the silt accumulation tank 11 for collection. Then the silt sweeping plate 24 will continue to walk, move upward, and then disengage from the bottom wall of the sewage tank body 1 and move back to the initial position. Through this one-way pushing and sweeping, the bottom silt can completely enter the silt accumulation tank 11, so that it can be uniformly sucked or manually processed, improving the silt cleaning speed and cleaning thoroughness.

[0035] As Figures 5-7 shown, in an embodiment, a limiting roller 25 is further arranged on the side of the walking gear 23 away from the submersible motor 22. An outer ring track 26 and an inner rail plate 27 located inside the outer ring track 26 are further arranged on the side wall of the sewage tank body 1. A limiting ring groove 28 for the limiting movement of the limiting roller 25 is opened on the opposite side of the outer ring track 26 and the inner rail plate 27. Through the engagement between the limiting roller 25 and the limiting ring groove 28, the walking gear 23 will not disengage from the upper end of the tooth ring track 2 when walking on the tooth ring track 2, ensuring the stability of the walk.

[0036] As Figure 3 shown, in an embodiment, first limiting sliding grooves 3 are opened on both side walls of the sewage tank body 1 perpendicular to the movement direction of the driving machine box 21. Ear plates 31 are arranged on the driving machine box 21. Limiting rods 32 with both ends being limited to move up and down in the first limiting sliding grooves 3 are movably inserted through the ear plates 31. Through the arrangement of the limiting rods 32, when the walking gear 23 moves on the tooth ring track 2, the silt sweeping plate 24 will not rotate, and it will only make a horizontal and vertical lateral movement relative to the bottom wall of the sewage tank body 1.

[0037] As Figures 11-14As shown, in one embodiment, the trapdoor mechanism includes a sealing plate assembly that movably closes the silt discharge opening 12 and a limiting assembly that limits the movement track of the sealing plate assembly. The sealing plate assembly includes a vertical sealing plate 4 and a horizontal sealing plate 41 that are combined into a T shape with each other, and connecting rods 42 whose two ends are respectively hinged to the outer surfaces of the two. Second limiting chutes 5 for limiting the sliding of the two ends of the vertical sealing plate 4 are provided on the inner wall of the sewage tank body 1. The limiting assembly includes a supporting fixed rod 51 fixedly arranged on the bottom wall of the sewage tank body 1, a lower hanging track 52 arranged on the lower surface of the horizontal sealing plate 41, a movable connecting piece 53 whose one end is hinged to the supporting fixed rod 51 and the other end is clamped and slidably limited in the lower hanging track 52, and a first spring 54 whose one end is arranged on the bottom wall of the sewage tank body 1 and the other end is arranged on the lower surface of the horizontal sealing plate 41. The triggering assembly includes a fixed arm rod 6 arranged on the horizontal sealing plate 41, a horizontal connecting shaft roller 61 arranged between the fixed arm rods 6, and a lifting plate 62 arranged on the silt cleaning plate 24 for lifting the horizontal connecting shaft roller 61. When the silt cleaning plate 24 retreats to sweep the silt onto the horizontal sealing plate 41, the lifting plate 62 at its upper end will insert into the bottom space of the horizontal connecting shaft roller 61. Then, under the continuous rotational movement of the traveling gear 23, the silt cleaning plate 24 will move forward and upward. At this time, the lifting plate 62 will continue to extend forward and simultaneously lift the horizontal connecting shaft roller 61, causing the horizontal sealing plate 41 to rotate and slide on the supporting fixed rod 51 through the arrangement of the movable connecting piece 53. While the horizontal sealing plate 41 rotates, it will push the vertical sealing plate 4 upward through the connecting rod 42, completely opening the silt discharge opening 12. At this time, the silt slides onto the silt accumulation pool 11 along the inclined horizontal sealing plate 41 for collection. At the same time, part of the water body in the sewage tank body 1 will pour into the silt accumulation pool 11 through the channel at the bottom of the horizontal sealing plate 41, thereby flushing the space at the bottom of the sewage tank body 1 and preventing the silt from flowing back into the sewage tank body 1. When the silt cleaning plate 24 moves upward to the highest point under the action of the traveling gear 23 and starts to walk back along the tooth ring track 2, the lifting plate 62 at its upper end will be withdrawn from the bottom of the horizontal connecting shaft roller 61. Then, the horizontal sealing plate 41 will move back and reset under the action of the first spring 54, and the vertical sealing plate 4 will be driven by the horizontal sealing plate 41 to move back and reset, thereby closing the silt discharge opening 12, completing the separation and collection of the silt and the water body. Through this reciprocating cycle of actions, the silt in the sewage tank body 1 can be completely cleaned up.

[0038] As Figures 9-10As shown, in one embodiment, a movable opening 63 is formed in the silt sweeping plate 24. Third limiting sliding grooves 64 are formed on both sides of the movable opening 63. Limiting sliding blocks 65 which are limited to slide in the third limiting sliding grooves 64 are arranged on both sides of the lifting plate 62. A fixed plate 66 is further arranged on the surface of the silt sweeping plate 24. A second spring 67 is arranged between the lifting plate 62 and the fixed plate 66. Since when the silt sweeping plate 24 slides onto the transverse sealing plate 41, it is orthogonally abutted against the transverse sealing plate 41, when it moves upward and drives one end of the transverse sealing plate 41 to move, movement resistance will be caused due to the abutment, resulting in jamming. Therefore, the lifting plate 62 is movably arranged to be limited to slide on the silt sweeping plate 24. When the silt sweeping plate 24 moves upward, the lifting plate 62 will be pressed by the transverse connecting shaft roller 61 and cannot move. As a result, the lifting plate 62 slides downward relative to the silt sweeping plate 24. When the lifting plate 62 slides to the bottommost position, at this time, there is a certain distance between the silt sweeping plate 24 and the transverse sealing plate 41. Then, under the continuous movement of the silt sweeping plate 24, the transverse sealing plate 41 can rotate and open.

[0039] As Figures 9-10 shown, in one embodiment, a mud blocking plate 68 for covering the movable opening 63 is arranged on the lower surface of the lifting plate 62. Since the movable opening 63 is formed in the silt sweeping plate 24, in order to prevent some silt from leaking from the movable opening 63 when the silt sweeping plate 24 is pushed horizontally, the mud blocking plate 68 is arranged to block it to a certain extent, reducing the amount of silt leakage.

[0040] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes within the meaning and scope of the equivalent elements of the claims in the present invention.
