Implementation

[0021] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0022] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0023] The connection method can be bonding, welding, bolt connection and other existing methods, depending on actual needs.

[0024] Examples, such as Figures 1 to 4 As shown, a dosing device for sewage treatment equipment includes a crushing box 10 for crushing solid drugs during sewage treatment and a base plate 1 that is easy to install and fix. Four universal wheels 5 for adjusting the moving direction are welded at the bottom of the base plate 1. The four universal wheels 5 are all equipped with a plug for parking. By limiting the universal wheels 5 by the plug, the movement state of the universal wheels 5 can be flexibly adjusted to improve the convenience of the device. Four fixed columns 6 for support are welded on one side of the top of the base plate 1. The tops of the four fixed columns 6 are connected to the bottom of the top plate 7. The setting of the fixed columns 6 makes it easy for the operator to drive the entire device to move by applying force to the fixed columns 6. The top plate 7 is connected to two of the fixed columns 6 through auxiliary support rods. The stability of the triangle is utilized to improve the stability of the overall structure of the device.

[0025] The top of the top plate 7 is fixed to the crushing box 10. A feed hopper 9 for placing solid medicines is provided on the top of the crushing box 10. Two drive motors 8 are screwed to one side of the crushing box 10. The output shaft of the drive motor 8 passes through the crushing box 10 and is connected to one end of a crushing roller 15. The other end of the crushing roller 15 is rotatably connected to the inner wall of the crushing box 10. Under the rotation of the drive motor 8, the crushing roller 15 is driven to crush the solid medicines entering through the feed hopper 9 to prevent the solid granular medicines from being difficult to dissolve in water, thereby increasing the production time of the liquid medicine for sewage treatment, which is not conducive to efficient production.

[0026] A hollow annular tube 14 for flushing is embedded in the inner wall of the crushing box 10, and a plurality of nozzles 17 are arranged on one side of the annular tube 14. The nozzles 17 are connected to the side walls of the annular tube 14 in a downwardly inclined shape. The outer wall of the nozzles 17 penetrates the inner wall of the crushing box 10 and is embedded on its surface. One end of the annular tube 14 is connected to a water pipe 11 penetrating the outer wall of the crushing box 10. A submersible high-pressure water pump is arranged on the inner bottom wall of the mixing barrel 4. A filter screen is arranged at the water inlet end of the high-pressure water pump to prevent blockage. The water outlet end of the high-pressure water pump is connected to the annular tube 14 through the connected water pipe 11. A nozzle 17 connected to the inner wall of the crushing box 10 is arranged on one side of the annular tube 14. The nozzles 17 are arranged at an inclination with the annular tube 14, so that the crushing roller 15 is flushed with water delivered by the high-pressure water pump, and the inner wall of the crushing box 10 is flushed under the action of the high-pressure water column to avoid the crushed and equally divided drug powder from adhering to the inner wall of the crushing box 10, thereby improving the practicability of the device.

[0027] A conduit 16 penetrating the top plate 7 is provided at the bottom of the crushing box 10. The conduit 16 penetrates the top plate 7 and is connected with the top of the stirring barrel 4, so that the crushed medicine powder is mixed with water and enters the interior of the stirring box 4, and the rotating motor 12 arranged on the top of the stirring box 4 is started. The output shaft of the rotating motor 12 drives the stirring shaft 22 connected thereto to rotate, and drives the stirring paddle 20 welded on the outer peripheral side of the stirring shaft 22 to rotate, and the sealing cover of the water injection port 13 is opened, and an appropriate amount of water for making the medicine liquid is injected into the stirring barrel 4. Four sets of fixed plates 18 are welded to the inner wall of the stirring barrel 4, and the opposite side of the fixed plate 18 is rotatably connected with a rotating shaft 21, and the outer peripheral side of the rotating shaft 21 is welded with a paddle 19. The paddle 19 cooperates with the stirring paddle 20 to complete the production of sewage treatment medicine inside the stirring barrel 4, thereby improving the production efficiency of the device.

[0028] A water pump 3 connected to the outer wall of the mixing barrel 4 is arranged on the side of the bottom plate 1 away from the fixed column 6. The water inlet end of the water pump 3 penetrates the side wall of the mixing barrel 4 and extends to the inside thereof without affecting the rotation of the stirring paddle 22 and the paddle 19. The water outlet end of the water pump 3 is connected to the outlet pipe 2 with a valve. Through the connection between the external pipeline and the outlet pipe 2, it is convenient to transport the prepared slurry through the water pump 3 to the inside of the sewage treatment equipment to complete the treatment of the sewage.
