Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a carbon source dispensing device for wastewater treatment. Background Technology

[0002] In wastewater treatment, slow-release carbon sources are essential elements for microbial growth, especially for denitrifying bacteria, which require essential nutrients for denitrification. When the influent organic matter is insufficient, an external slow-release carbon source is needed to promote microbial growth and activity, thereby improving the degradation efficiency of organic matter in the wastewater and achieving wastewater treatment goals such as denitrification.

[0003] Existing devices primarily use a feeding assembly to add a slow-release carbon source into the treatment tank. Many existing technologies are similar to a slow-release carbon source addition device for wastewater treatment. The structure of device CN222196830U includes a wastewater treatment tank, a fixed plate fixedly connected to the right side of the tank, a support column fixedly connected to the top of the fixed plate, and a feeding box fixedly connected to the top of the support column. This invention allows the slow-release carbon source to be added into the inner cavity of the wastewater treatment tank, facilitating wastewater treatment. However, there are still areas for improvement in this device.

[0004] Existing devices mainly involve throwing slow-release carbon sources into the treatment tank. However, some devices struggle to evenly distribute the slow-release carbon sources into the treatment tank, resulting in inadequate mixing of wastewater and slow-release carbon sources. Furthermore, some devices have difficulty controlling the number of exposed dispensing holes, making it difficult to control the release rate of the slow-release carbon sources and reducing the device's efficiency and practicality. Therefore, to solve the above problems, a carbon source dispensing device for wastewater treatment is proposed. Utility Model Content

The right end of the transmission screw 22 passes through the left side wall of the support frame 12 and is movably connected to the right side of the inner wall of the support frame 12. This design enables the first motor 21 to drive the transmission screw 22 to rotate in a limited position. A pushing sleeve 23 is threaded onto the middle of the outer wall of the transmission screw 22. The upper part of the outer wall of the pushing sleeve 23 is fixedly connected to the middle of the bottom of the sliding frame 13. This design enables the transmission screw 22 to drive the pushing sleeve 23 and the sliding frame 13 to slide left and right.

[0020] Sliding sleeves 24 are fixedly connected to the four corners of the bottom of the sliding frame 13. Limiting rods 25 are inserted into the inner wall of the sliding sleeves 24. The two ends of the limiting rods 25 are fixedly connected to the two sides of the inner wall of the support frame 12.

This design allows the second motor 31 to drive the movable screw 32 to rotate in a limited position, causing the movable screw 32 to drive the lifting screw 33 and the sleeve 34 to slide up and down, facilitating precise control of the position of the sleeve 34.

[0022] Working principle: When it is necessary to push the sliding frame 13, the first motor 21 is started by the control console 16. The first motor 21 drives the transmission screw 22 to rotate in a limited position. The transmission screw 22 drives the push sleeve 23 to slide left and right. The push sleeve 23 drives the sliding frame 13 to slide left and right. The sliding frame 13 drives the sliding sleeve 24 and the ball 27 to slide along the limit rod 25, thus realizing the pushing operation of the sliding frame 13.

[0023] When it is necessary to adjust the delivery rate, the second motor 31 is first started through the control console 16. The second motor 31 drives the movable screw 32 to slide to the limit, the movable screw 32 drives the lifting screw 33 to slide up and down, and the lifting screw 33 drives the sleeve 34 to slide synchronously, thus realizing the adjustment operation of the delivery rate. The operation ends here.
