Description

Technical field:

[0002] The invention relates to the field of water collection tank treatment in waterworks, and mainly relates to a device for cleaning the outer surface of a water collection tank in a horizontal flow sedimentation tank in the water supply industry. Background technology:

[0004] Moss and algae are prone to grow on the surface and inside of the water collection tank of the water plant's horizontal flow sedimentation tank, blocking the overflow hole. At the same time, the death of the algae and moss has a certain impact on the water quality. It is also very unsightly. A large number of manpower must be organized every year to clean the algae and moss. When there is moss and algae inside the water collection tank, it is very slippery and people cannot stand steadily, which poses a certain safety risk. It is too cold to clean the water in the winter. In the summer, when the water temperature and light are suitable, the algae and moss grow very rapidly. The surface that has just been cleaned will often grow again after a few days. In this case, it is particularly urgent to develop a cleaning equipment to replace manpower. Summary of the invention:

[0006] The purpose of the present invention is to make up for the defects of the existing technology and provide a device for cleaning the outer surface of the water collection tank of the horizontal flow sedimentation tank in the water supply industry. It utilizes the existing mud discharge machine facilities for embedded development to save money, can realize the cleaning of the two outer sides of the water collection tank, and the design mechanism is simple and firm and can be reused for a long time.

[0007] The present invention is achieved through the following technical solutions:

[0008] A device for cleaning the outer surface of a water collection tank in a horizontal flow sedimentation tank in the water supply industry, comprising a cleaning mechanism fixedly installed at intervals on a sludge discharger bracket and cooperating with two outer side surfaces of the water collection tank, the cleaning mechanism comprising a vertically arranged main body bracket, the upper and lower ends of the main body bracket being respectively provided with mounting and fixing frames for mounting and fixing, a brush roller mechanism being provided parallel to the main body bracket on one side of the main body bracket, the brush roller mechanism comprising a rotating shaft, a brush roller being fixedly installed on the rotating shaft, bristles being distributed on the brush roller, the two ends of the rotating shaft being respectively connected to the main body bracket via a connecting frame, and the rotation of the rotating shaft being driven by a motor at its upper end.

[0009] The main body bracket, installation and fixing frame, and connecting frame are all made of aluminum alloy profiles.

[0010] The main support is a square aluminum alloy column, and T-shaped slots are respectively provided on the four sides of the square aluminum alloy column. The positions of the mounting bracket and the connecting bracket on the main support are adjustable.

[0011] The mounting bracket includes a fixing beam, which has the same structure as the main bracket. The fixing beam is horizontally arranged in the front-to-back direction. The upper end face and both sides of the inner side of the fixing beam are respectively connected and fixed to the outer side face of the main bracket through aluminum alloy fixing connectors. A guide fixing bolt that cooperates with the T-slot of the main bracket is installed in the fixing hole of the aluminum alloy fixing connector and is locked and fixed by a nut.

[0012] The two ends of the rotating shaft are fixedly mounted on the connecting frame through fixed sleeves, and the ends of the rotating shaft and the fixed sleeves rotate through bearings. The connecting frame is a rod structure arranged horizontally on the left and right, and the profile structure it adopts is the same as that of the main bracket.

[0013] The front and rear sides of the connecting end of the rod body are respectively connected and fixed to the main bracket through a horizontal T-shaped connecting plate, and the horizontal section and vertical section of the T-shaped connecting plate are respectively provided with mounting holes, and guide fixing bolts that cooperate with the T-shaped slots of the main bracket are installed in the mounting holes and are locked and fixed by nuts.

[0014] Angle connectors are respectively installed on the upper and lower end surfaces of the connecting end of the rod body. The corner connectors are provided with mounting holes. Gaskets and guide fixing bolts that match the T-slots of the main bracket are installed in the mounting holes and are locked and fixed by nuts.

[0015] The guide fixing bolt is a T-shaped structure, the horizontal section of the T-shaped structure is a guide block, and the end of the vertical section is provided with a threaded section.

[0016] The power supply AC contactor coil of the driving motor is connected to the normally open contact of the mud discharger travel motor contactor through a wire, and an inductive proximity switch is connected in series between them. The inductive proximity switch senses the position of the mud discharger travel to control whether the roller brush is working.

[0017] The principle is: using the existing mud discharger facilities for embedded development to save money, the cleaning mechanism is fixedly installed on the bracket of the mud discharger at intervals, and the specific installation method is: the upper end of the cleaning mechanism is fixed to the bracket of the mud discharger by installing U-shaped clips at both ends of the fixed mounting frame, and the bottom end is connected and fixed to the bottom end of the support rod of the mud discharger through the fixed mounting frame at the lower end.

This design mechanism is simple, firm and can be reused for a long time. Without increasing power and facilities, it can realize the cleaning of both sides of the water collection tank as the mud discharger is running, saving manpower and having obvious scrubbing effect. Compared with the static brush roller, the rotating brush is not easy to adhere to algae and alum flowers, and no aquatic animals will gather. The floating objects on the pool surface can be driven to one end of the guide trough and filtered by the filter tank.

[0027] See attached figure.

[0028] A device for cleaning the outer surface of a water collection tank in a horizontal flow sedimentation tank in the water supply industry includes a cleaning mechanism fixedly installed at intervals on a sludge discharger bracket and cooperating with two outer side surfaces of the water collection tank. The cleaning mechanism includes a vertically arranged main body bracket 1, and the upper and lower ends of the main body bracket 1 are respectively equipped with mounting brackets 2 for mounting and fixing. A brush roller mechanism is provided on one side of the main body bracket 1 in parallel therewith, and the brush roller mechanism includes a rotating shaft 3, on which a brush roller 4 is fixedly installed, and bristles are distributed. The two ends of the rotating shaft 3 are respectively connected to the main body bracket 1 through a connecting frame 5, and the rotation of the rotating shaft 3 is driven by a driving motor 6 at its upper end. The output shaft end of the motor 6 is transmission-connected to the rotating shaft 3 through a plum blossom-shaped coupling, and the plum blossom-shaped coupling eliminates rotational vibration and improves stability.

[0029] Furthermore, the main frame 1, the mounting bracket 2, and the connecting bracket 5 are all made of aluminum alloy profiles.

[0030] Furthermore, the main support 1 is a square aluminum alloy column, and T-shaped slots 7 are respectively provided on the four sides of the square aluminum alloy column. The positions of the mounting bracket 2 and the connecting bracket 5 on the main support 1 are adjustable.

[0031] Furthermore, the mounting bracket 2 includes a fixing beam 2-1, which has the same structure as the main bracket 1. The fixing beam 2-1 is horizontally arranged along the front-to-back direction. The upper end face and both sides of the inner side face of the fixing beam 2-1 are respectively connected and fixed to the outer side face of the main bracket 1 through aluminum alloy fixing connectors 2-2. A guide fixing bolt that cooperates with the T-slot of the main bracket is installed in the fixing hole of the aluminum alloy fixing connector 2-2 and is locked and fixed by a nut.

[0032] Furthermore, the two ends of the rotating shaft 3 are fixedly mounted on the connecting frame 5 through fixed sleeves 8, and the ends of the rotating shaft 3 and the fixed sleeves 8 rotate through bearings. The connecting frame 5 is a rod structure arranged horizontally on the left and right, and the profile structure it adopts is the same as that of the main bracket 1.

[0033] Furthermore, the front and rear side surfaces of the connecting end of the rod body are respectively connected and fixed to the main bracket 1 through a horizontal T-shaped connecting plate 9. The horizontal section and vertical section of the T-shaped connecting plate 9 are respectively provided with mounting holes. Guide fixing bolts that cooperate with the T-slot of the main bracket are installed in the mounting holes and are locked and fixed by nuts.

[0034] Furthermore, corner connectors 10 are respectively installed on the upper and lower end surfaces of the connecting end of the rod body. The corner connectors 10 are provided with mounting holes. Gaskets and guide fixing bolts that match the T-slots of the main bracket are installed on the mounting holes and are locked and fixed by nuts.

[0035] Furthermore, the guide fixing bolt is a T-shaped structure, the horizontal section of the T-shaped structure is a guide block, and the end of the vertical section is provided with a threaded section.

[0036] Furthermore, the power supply AC contactor coil of the driving motor 6 is connected to the normally open contact of the mud discharger travel motor contactor through a wire, and an inductive proximity switch is connected in series between them. The inductive proximity switch senses the position of the mud discharger travel and controls whether the roller brush is working. The driving power supply AC contactor coil power supply circuit of the cleaning equipment is connected to the normally open contact of the mud discharger travel motor contactor in parallel and then connected in series with the inductive proximity switch. When the mud discharger travel contactor is energized, it changes from normally open to normally closed. When the mud discharger travels to one end of the water collection tank, the inductive proximity switch is blocked by the water collection tank and changes from normally open to normally closed. The power supply contactor coil of the cleaning equipment is energized, the contactor is closed, and the cleaning equipment is energized to rotate. After the mud discharger stops, the contactor coil loses power, the power supply circuit is disconnected, and the inductive proximity switch will not be energized if it does not sense the index groove. There is no need to manually turn on the switch, and it automatically starts and stops.

[0037] When the above structure is used:

[0038] Embedded development leverages existing equipment and facilities, saving money. The design is simple, robust, and reusable. A desludging machine is used daily to remove mud from the bottom of the horizontal flow sedimentation tank. The distance between the desludging machine and the surface of the sump remains constant, making it suitable for installing cleaning equipment. The desludging machine's upper and lower angle steels facilitate secure mounting.

[0039] The main equipment can be divided into three types: bracket structure, drive motor, and brush roller. Considering the assembly combination movement and overall weight issues, it is assembled with industrial aluminum alloy profile parts.

[0040] The aluminum alloy profile assembly features a structure that allows for easy distance adjustment. This is because the left and right end surfaces of the sump are not aligned, resulting in a large error in the distance. The assembly distance needs to be adjusted according to actual conditions. The uneven surface is caused by a recessed rib in the row groove, which results in the sump being convex at the top and bottom, and concave near the rib. This error is approximately 5 cm. Furthermore, the front-to-back distance of the sump also has an error, which poses a significant challenge to the compatibility of the bracket structure and the roller brush. During installation, the cement at the bottom also poses a risk of scratching the bracket, requiring length adjustment. Furthermore, aluminum alloy profiles are lightweight and less prone to rust, but they can produce pitting on the surface. References show that pitting prevents further internal reactions, has no effect on water quality, and has a negligible impact on bracket strength.

[0041] During use: The selected torque of the drive motor must be able to drive a 90cm long brush for cleaning, and it must be easy to assemble. The selection of the motor is synchronized with the model and size of the bearing. First, select the bearing model supc204, and then select the reduction motor model with similar assembly dimensions, power 120w, speed 70, speed ratio 20:1. The computer calculates that the assembly distance has an error of 1.7 mm, and the motor bracket needs to be ground off 1.7 mm. Later, grinding is too time-consuming, so the bearing is raised by adding a gasket.

[0042] Through experiments, the torque of the motor was tested. When the power remained unchanged at 120W and the speed ratio was 15:1 and the speed was 100 and the torque was 8.5 N*M, the motor was blocked and overheated seriously. The reduction ratio was increased again and the torque of the reduction gearbox with 20:1 was 11.5 N*m. There was no obvious heating and no motor blocking. The deformation of the roller brush in the water was reduced due to the reduction in speed, and the torque consumed by friction with water was reduced, so the brushing effect was significantly improved.

[0043] The selection of the roller brush is particularly important and is the core of whether the equipment can work normally. It must be able to adapt to the non-ideal brush surface. First, a roller brush with a bristle length of 100cm and a single-side bristle length of 8cm was selected. However, after assembly, it was found that the brush wire could not reach the place with large errors. Later, the single-side bristle length was lengthened to 13cm, and the assembly distance from the brush surface was 45mm, which solved this problem.

[0044] The filaments of the roller brush were selected to be nylon, primarily based on considerations such as wear resistance, deformation, water reactivity, and longevity. Nylon offers significant advantages over plastic in these areas. Filament diameters between 0.4 mm and 0.8 mm are suitable for normal use. Because the motor speed is low, the friction between the brush and the water causes minimal deformation. Increasing the speed requires a larger diameter to resist deformation caused by friction. The internal metal shaft of the roller brush is made of 304 stainless steel, with a 6 cm excess at the end of the shaft and a 27 cm excess at the motor connection end. This allows for a safe distance from the water surface to prevent water from splashing onto the motor, ensuring a safe installation position.

[0045] In summary: it saves manpower and has obvious scrubbing effect. Compared with the static brush, the rotating brush of the roller is not easy to attach algae and blooms, and there will be no gathering of aquatic animals. The floating objects on the pool surface can be driven to one end of the guiding trough and filtered by the filter tank. The equipment on the diversion wall can clean the diversion wall.
