Description

Technical Field

[0001] The utility model relates to the technical field of installation of a sludge scraper, in particular to an installation structure of a sludge scraper for sewage treatment. Background Art

[0002] The scraper is used in the circular sedimentation tank with a larger diameter in the urban sewage treatment plant, water plant and industrial wastewater treatment to remove the sludge settled at the bottom of the tank and skim the scum on the surface of the tank. The driving device drives the scraper to rotate around the center of the sedimentation tank. The driving device is the motor. After the raw water is precipitated in the sedimentation tank, the supernatant is discharged from the overflow weir plate. The sludge settled at the bottom of the tank, driven by the logarithmic spiral scraper, slowly flows along the bottom of the tank to the central mud collection tank and is discharged through the mud discharge pipe. At the same time, the scum on the surface of the tank is concentrated in the area between the scum scraper and the scum baffle. When the working bridge passes through the scum discharge cylinder floating on the surface of the tank, the scum discharge cylinder is pressed below the liquid surface, and the scum is discharged out of the tank through the discharge cylinder.

[0003] At present, when installing a scraper on a sewage sedimentation tank, it is necessary to first set a main beam above the sedimentation tank, and then set the driving device of the scraper, that is, the motor, on the main beam, and the central transmission shaft of the scraper is installed on the bottom of the sedimentation tank through a bearing;

[0004] Generally, the motor is fixedly connected to the main beam, and the position of the motor on the main beam cannot be adjusted. Once there is an installation error between the motor and the central transmission shaft of the scraper, the motor will not be able to drive the scraper to rotate. Therefore, the applicant has developed a new technical solution in the actual production process to solve the above technical problems. Utility Model Content

[0023] A scraper installation structure for sewage treatment, such as Figure 1 and Figure 2, including a main beam 1 arranged at the upper end of the sewage sedimentation tank 2 and a motor 11 sliding on the main beam 1, the main beam 1 spans the upper pool mouth of the sewage sedimentation tank 2, and a through hole 13 is opened on the main beam 1 for the central transmission shaft 12 of the scraper to pass through. The size of the through hole 13 is larger than the diameter of the central transmission shaft 12 of the scraper, the purpose is to facilitate the installation of the central transmission shaft 12 of the scraper, the central transmission shaft 12 of the scraper is coaxially fixed with a driving column 131 at one end passing through the top of the main beam 1, the motor 11 drives the driving column 131 to rotate through a connecting piece, there is a gap between the lower end face of the driving column 131 and the upper end face of the main beam 1, and the lower end face of the driving column 131 is embedded with a plurality of balls that contact the upper end face of the main beam 1, so as to improve the stability of the rotation of the driving column 131, and it is not affected by the installation accuracy, and the driving column 131 can be installed after the central transmission shaft 12 of the scraper passes through the through hole 13.

[0024] like Figure 1 and Figure 2 The motor 11 drives the driving column 131 to rotate through the connecting piece, and the rotation of the driving column 131 drives the central transmission shaft of the scraper to rotate, thereby facilitating the operation of the scraper. At this time, the motor 11 is arranged on one side of the driving column 131 and can slide, thereby facilitating the adjustment of the position of the motor 11, so that the motor 11 drives the driving column 131 to rotate, so as to facilitate the operation of the scraper.

[0025] like Figure 1 and Figure 2 The connecting member includes two L-shaped fixing rods 14 arranged along the same straight line on the main beam 1, each fixing rod 14 is fixed to the main beam 1 at a distance, and the horizontal end is located above the driving column 131 and the motor 11, and the horizontal end of each fixing rod 14 is connected by a rotating rod 141, and the rotating rod 141 is rotatably connected to each fixing rod 14, and the rotating rod 141 is circumferentially provided with a plurality of driving teeth 142 on the outer wall between the two fixing rods 14, and each driving tooth 142 is distributed along the length direction of the rotating rod 141, and a driving column 143 is coaxially fixed on the rotating shaft of the motor 11, and the upper end surfaces of the driving column 131 and the driving column 143 are circumferentially provided with a plurality of driven teeth 144 meshing with the driving teeth 142.

[0026] like Figure 1 and Figure 2 At this time, the motor 11 drives the driving column 143 to rotate, so that the driven teeth 144 on the driving column 143 engage with the driving teeth 142, thereby driving the rotating rod 141 to rotate, and the rotating rotating rod 141 drives the driven teeth 144 on the driving column 131 to rotate, thereby realizing the rotation of the driving column 131 and the central transmission shaft 12 of the scraper.

[0027] like Figure 1 and Figure 2, the main beam 1 is slidably connected with a vertical moving plate 15 on one side through the hole 13. At this time, the moving plate 15 and the fixed rod 14 are respectively located on both sides of the driving column 131 and the driving column 143. The motor 11 is fixed on the moving plate 15. In order to facilitate the installation of the motor 11, the lower end of the moving plate 15 can have a horizontally distributed plate to fix the motor 11. The main beam 1 is provided with a driving member that drives the moving plate 15 to move. At this time, the driving member drives the motor 11 to move, and then drives the driving column 143 to move, and the moving direction is along the length direction of the rotating rod 141; the position where the driving teeth 142 and the driven teeth 144 are meshed is lower than the lower end surface of the horizontal end of the fixed rod 14, so that the driving column 143 can move out of the driving teeth 142.

The adjustable position of the motor 11 can drive the central transmission shaft 12 of the scraper to rotate, reducing the situation where the motor 11 cannot drive the central transmission shaft 12 of the scraper to rotate due to installation errors.

[0028] like Figure 1 and Figure 2 The driving member includes a fixed block 151 disposed on the main beam 1 and located on one side of the moving plate 15, a screw rod 152 is threadedly connected to the fixed block 151, one end of the screw rod 152 is rotatably connected to the moving plate 15, and the other end passes through the fixed block 151 and is provided with a hand wheel 153. The screw rod 152 is rotated by the hand wheel 153, so that the screw rod 152 drives the moving plate 15 to move.

[0029] like Figure 2 and Figure 3 The upper end surfaces of the driving column 131 and the driving column 143 can be detachably connected with a replacement plate 16, and each driven tooth 144 is evenly arranged on the circumference of the replacement plate 16. At this time, the arrangement of the replacement plate 16 facilitates the replacement of the driven teeth 144.

[0030] like Figure 2 and Figure 3 The upper end surfaces of the driving column 131 and the driving column 143 are provided with a plurality of positioning holes 161, and the replacement plate 16 is provided with positioning columns 162 that enter the positioning holes 161 on the side of the plate away from the driven teeth 144. At this time, it is only necessary to install the positioning columns 162 in the positioning holes 161, so that the replacement plate 16 can be installed on the driving column 143 and the driving column 131, so that the replacement plate 16, the driving column 131 and the driving column 143 can rotate together.

[0031] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
