Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a sludge removal mechanism for sedimentation tanks used in sewage treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life for ordinary people. A large amount of sludge is generated during wastewater treatment, and to ensure the efficiency and effectiveness of the treatment, the sludge needs to be discharged promptly.

[0003] In practice, existing sludge removal devices are easily limited by the application scenarios and cannot meet the sludge removal needs of different scenarios. This results in the need for manual sludge removal, which reduces the overall flexibility of the equipment. In addition, the equipment requires a large amount of power for auxiliary operation, which increases the overall operating cost.

[0004] Therefore, this utility model provides a sludge removal mechanism for sedimentation tanks used in sewage treatment. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a sludge removal mechanism for sedimentation tanks in sewage treatment.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a sludge removal mechanism for sedimentation tanks in sewage treatment, comprising a mobile platform.

[0007] The top of the mobile platform is provided with an installation slot, and a water storage tank is fixedly connected to one side of the installation slot.

[0008] The installation slot houses a pulverizing and processing box, which in turn houses a sludge recovery box. A conveyor belt is installed above the sludge recovery box, and a recovery base plate is installed on one side of the conveyor belt. Two symmetrically distributed installation partitions are installed on the top of the recovery base plate, and a rotating frame is installed on the top of each of the two installation partitions. A rotating shaft is rotatably connected inside the two installation partitions, and equidistantly distributed stirring blades are installed on the outer side of the rotating shaft. Rotating discs are installed at both ends of the rotating shaft, and equidistantly distributed fixing rods are installed between the two rotating discs. Equidistantly distributed stirring rods are installed on the outer side of the fixing rods. When cleaning sludge from the normal sedimentation tank, no auxiliary sludge discharge mechanism is required. The second drive motor rotates the rotating shaft, which in turn synchronously rotates the rotating discs at both ends and the outer stirring blades, thus recovering the sludge.

[0009] The mobile platform is equipped with an auxiliary sludge removal mechanism at its bottom. The auxiliary sludge removal mechanism includes a mounting top plate, which is fixedly connected to the bottom of the mobile platform. A fixed frame is installed at the bottom of the mounting top plate, and symmetrically distributed fixed columns are installed inside the fixed frame. Two equally spaced sliding mounting plates are installed on the outer sides of the fixed columns. Sludge removal and dispersing plates are slidably installed between the two sliding mounting plates on the same side. Each sludge removal and dispersing plate has equally spaced limiting grooves inside. When sludge removal is required in low-lying areas, the auxiliary sludge removal mechanism is installed on the mobile platform. It is suitable for sludge removal in ditch-like scenarios, using the multi-directionally installed sludge removal and dispersing plates to scrape and clean the sludge.

[0010] In a preferred embodiment, the top of the fixed frame is fixedly connected with symmetrically distributed fixed blocks, and a reinforcing connecting rod is installed between two fixed blocks on the same side. The bottom of the fixed frame is equipped with equidistantly distributed fixed insert rods extending into the mounting top plate. These fixed insert rods reinforce the connection between the fixed frame and the mounting top plate, thereby ensuring proper connection between the auxiliary sludge discharge mechanism and the moving platform for convenient operation. The crushing and processing box contains two rotatably connected crushing rollers. Two third drive motors are installed on one side of the crushing and processing box to cooperate with the crushing rollers. The operation of these third drive motors drives the corresponding crushing rollers to rotate, thus crushing the recovered sludge for convenient subsequent unified cleaning.

[0011] The technical effect of adopting the above-mentioned further solution is that the fixed frame and the mounting top plate are reinforced and connected by the fixed insertion rod, thereby enabling normal connection between the auxiliary sludge discharge mechanism and the mobile platform, facilitating normal operation and use.

[0012] In a preferred embodiment, a rotating column is rotatably connected inside the sludge recovery box and located on one side of the rotating shaft. A first drive motor is fixedly connected to one side of the sludge recovery box, and the output end of the first drive motor extends into the sludge recovery box and is fixedly connected to the rotating column. The rotation of the first drive motor drives the rotating column to rotate inside the sludge recovery box, which facilitates fine-tuning of the installation angle of the conveyor belt, improves the flexibility of equipment use, reduces sludge falling, and facilitates manual cleaning later. An electrical control box is installed on the top of the mobile platform and located on one side of the water storage tank. A conveying channel is installed between the water storage tank and the crushing and processing box. A valve is fixedly connected to the outside of the conveying channel. A water pump is installed inside the water storage tank. When the water pump operates, the valve is opened, and water is conveyed into the crushing and processing box through the conveying channel to assist in cleaning the crushing and processing box.

[0013] The technical effect of adopting the above-mentioned further solution is that the first drive motor drives the rotating column to rotate inside the sludge recovery box, which facilitates the fine adjustment of the installation angle of the conveyor belt, improves the flexibility of equipment use, and reduces sludge falling, making it easier for manual cleaning later.

[0014] In a preferred embodiment, the mobile platform is equipped with casters on all four sides of its bottom. The casters are used to drive the entire mobile platform to move normally, facilitating mud removal operations while moving.

[0015] The technical effect of adopting the above-mentioned further solution is that the casters are used to drive the entire mobile platform to move normally, which facilitates the mud removal operation while moving.

[0016] In a preferred embodiment, a dust cover is installed on the top of the electrical control box, and a control panel is installed inside the electrical control box. The control panel is located at the bottom of the electrical control box, and both the first drive motor and the second drive motor are electrically connected to the control panel. The control panel is used to control the operation of the first drive motor and the second drive motor, thereby realizing unified management of the power equipment.

[0017] The technical effect of adopting the above-mentioned further solution is that the control panel is used to control the operation of the first drive motor and the second drive motor, realizing unified management of power equipment.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] By setting up a mobile platform, water storage tank, sludge recovery tank, and auxiliary sludge discharge mechanism, during use, the control panel is opened, and the fixed frame and mounting top plate are reinforced and connected via fixing rods, thus ensuring normal connection between the auxiliary sludge discharge mechanism and the mobile platform for convenient operation. This facilitates cleaning of the crushing and processing tank. The casters drive the entire mobile platform, allowing for simultaneous sludge discharge. The first drive motor rotates the rotating column inside the sludge recovery tank, facilitating fine-tuning of the conveyor belt's installation angle, improving the equipment's flexibility, reducing sludge spillage, and simplifying subsequent manual cleaning. When the normal sedimentation tank is leveled... During sludge cleaning, no auxiliary sludge discharge mechanism is required. The second drive motor rotates the rotating shaft, which in turn rotates the rotating discs at both ends and the outer stirring blades, thus recycling the sludge. The sludge discharge and dispersing plates are equipped with equidistantly distributed limiting grooves. When sludge discharge is required in low-lying areas, the auxiliary sludge discharge mechanism is installed on the mobile platform. This design is suitable for sludge discharge in ditch-like environments. The multi-directionally installed sludge discharge and dispersing plates scrape and clean the sludge, facilitating easy switching of equipment operation modes and improving the overall flexibility of the equipment to meet the needs of different scenarios.

[0031] 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.

[0032] like Figures 1-4 As shown, this embodiment provides a technical solution: a sludge removal mechanism for a sedimentation tank in sewage treatment, including a mobile platform 1, an installation groove 24 on the top of the mobile platform 1, and a water storage tank 2 fixedly connected to one side of the installation groove 24.

[0033] The crushing and processing box 22 is installed inside the installation slot 24. The sludge recovery box 3 is installed inside the crushing and processing box 22. A conveyor belt 25 is installed above the sludge recovery box 3. A recovery base plate 46 is installed on one side of the conveyor belt 25. Two symmetrically distributed installation partitions 5 are installed on the top of the recovery base plate 46. A rotating frame 4 is installed on the top of each of the two installation partitions 5. A rotating shaft 41 is rotatably connected inside the two installation partitions 5. Equally spaced stirring blades 47 are installed on the outside of the rotating shaft 41. Rotating discs 43 are installed at both ends of the rotating shaft 41. Equally spaced fixing rods 44 are installed between the two rotating discs 43. Equally spaced stirring rods 45 are installed on the outside of the fixing rods 44. The conveying channel 23 is located on the side of the crushing and processing box 22 away from the water storage tank 2.

[0034] In this solution, when cleaning the sludge in the normal sedimentation tank, there is no need to install the auxiliary sludge discharge mechanism 6. The second drive motor 42 drives the rotating shaft 41 to rotate. When the rotating shaft 41 rotates, it will synchronously drive the rotating disks 43 at both ends to rotate and drive the outer stirring blades 47 to rotate, so as to recycle the sludge.

[0035] An auxiliary sludge removal mechanism 6 is installed at the bottom of the mobile platform 1. The auxiliary sludge removal mechanism 6 includes a mounting top plate 61. The mounting top plate 61 is fixedly connected to the bottom of the mobile platform 1. A fixed frame 62 is installed at the bottom of the mounting top plate 61. A symmetrically distributed fixed column 64 is installed inside the fixed frame 62. Two equally spaced sliding mounting plates 65 are installed on the outside of the fixed column 64. A sludge removal and dispersing plate 66 is slidably installed between the two sliding mounting plates 65 on the same side.

[0036] In this solution, the sludge dispersing plate 66 is provided with equidistantly distributed limiting grooves 67. When sludge is to be discharged in a low-lying area, the auxiliary sludge discharge mechanism 6 is installed on the mobile platform 1. It is suitable for sludge discharge in ditch-like scenarios. The sludge is scraped and cleaned by the multi-directionally installed sludge dispersing plate 66.

[0037] Going a step further, such as Figures 2-3 As shown: The top of the fixed frame 62 is fixedly connected with symmetrically distributed fixed blocks 68, and a reinforcing connecting rod 69 is installed between two fixed blocks 68 on the same side. The bottom of the fixed frame 62 is equipped with fixed insert rods 63 that are evenly distributed and extend into the installation top plate 61.

[0038] In this solution, the fixed frame 62 and the mounting top plate 61 are reinforced and connected by the fixed insertion rod 63, thereby enabling normal connection between the auxiliary sludge discharge mechanism 6 and the mobile platform 1 for convenient normal operation.

[0039] Going a step further, such as Figure 4 As shown: In this scheme, two crushing rollers are rotatably connected inside the crushing and processing box 22;

[0040] In this solution, two third drive motors are installed on one side of the crushing and processing box 22 to work with the crushing rollers. The operation of the third drive motors drives the corresponding crushing rollers to rotate, thereby crushing the recovered sludge and facilitating subsequent unified cleaning.

[0041] An electrical control box 21 is installed on the top of the mobile platform 1 and on one side of the water storage tank 2. A conveying channel 23 is installed between the water storage tank 2 and the crushing and processing box 22.

[0042] In this scheme, a valve is fixedly connected to the outside of the conveying channel 23, and a water pump is installed inside the water storage tank 2. When the water pump is running, the valve is opened, and water is conveyed into the crushing and processing box 22 through the conveying channel 23 to clean the crushing and processing box 22.

[0043] The bottom of the mobile platform 1 is equipped with casters 26 on all four sides;

[0044] In this solution, the casters 26 are used to drive the mobile platform 1 to move normally, making it convenient to perform mud removal operations while moving.

[0045] Going a step further, such as Figure 4 As shown, in this scheme, a rotating column 32 is rotatably connected inside the sludge recovery box 3 and on one side of the rotating shaft 41. A first drive motor 31 is fixedly connected to one side of the sludge recovery box 3. The output end of the first drive motor 31 extends into the sludge recovery box 3 and is fixedly connected to the rotating column 32.

[0046] In this scheme, the first drive motor 31 operates, driving the rotating column 32 to rotate inside the sludge recovery box 3, which facilitates fine adjustment of the installation angle of the conveyor belt 25, improves the flexibility of equipment use, and reduces sludge falling, making it easier for manual cleaning later.

[0047] Going a step further, such as Figure 4 As shown, in this scheme, a dust cover is installed on the top of the electrical control box 21, and a control panel is installed inside the electrical control box 21. The control panel is located below the electrical control box 21, and the first drive motor 31 and the second drive motor 42 are both electrically connected to the control panel.

[0048] In this solution, the control panel is used to control the operation of the first drive motor 31 and the second drive motor 42, realizing unified management of power equipment.

[0049] Working principle:

[0050] like Figure 1-4 As shown:

[0051] By setting up a mobile platform 1, a water storage tank 2, a sludge recovery tank 3, and an auxiliary sludge discharge mechanism 6, when in use, the control panel is opened, and the fixed frame 62 and the mounting top plate 61 are reinforced and connected by the fixed rod 63, thereby connecting the auxiliary sludge discharge mechanism 6 and the mobile platform 1 normally for convenient normal operation. Two third drive motors are installed on one side of the crushing and processing box 22 to work with the crushing rollers. The operation of the third drive motors drives the corresponding crushing rollers to rotate, thereby crushing the recovered sludge for convenient unified cleaning later.

[0052] A valve is fixedly connected to the outside of the conveying channel 23. A water pump is installed inside the water storage tank 2. When the water pump is running, the valve is opened, and water is delivered into the crushing and processing box 22 through the conveying channel 23 to clean the crushing and processing box 22. The casters 26 are used to drive the mobile platform 1 to move normally, which facilitates the sludge discharge operation while moving. The first drive motor 31 drives the rotating column 32 to rotate inside the sludge recovery box 3, which facilitates the fine adjustment of the installation angle of the conveyor belt 25, improves the flexibility of equipment use, reduces sludge falling, and facilitates manual cleaning later.

[0053] The control panel is used to control the operation of the first drive motor 31 and the second drive motor 42, realizing unified management of electrical equipment.

[0054] When cleaning sludge from a normal sedimentation tank on flat ground, the auxiliary sludge discharge mechanism 6 is not required. The second drive motor 42 rotates, driving the rotating shaft 41 to rotate. When the rotating shaft 41 rotates, it simultaneously drives the rotating discs 43 at both ends to rotate and the outer stirring blades 47 to rotate, thus recycling the sludge. The sludge discharge and dispersing plates 66 are equipped with equidistantly distributed limiting grooves 67. When sludge discharge is required in low-lying areas, the auxiliary sludge discharge mechanism 6 is installed on the mobile platform 1. This is suitable for sludge discharge in ditch-like scenarios. The sludge is scraped and cleaned by the multi-directionally installed sludge discharge and dispersing plates 66, which facilitates switching between equipment operation modes during actual use, improves the overall flexibility of the equipment during operation, and meets the needs of different scenarios.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
