Description

Technical Field

[0001] This utility model relates to the technical field of modified starch processing equipment, specifically a wastewater sedimentation tank for modified starch processing. Background Technology

[0002] Modified starch is produced by treating starch molecules using physical, chemical, or enzymatic methods. This process improves the properties of natural starch and expands its applications by introducing new functional groups or altering the size and properties of starch granules. The goal is to change the natural characteristics of starch to better suit specific applications. However, the processing of modified starch generates a large amount of wastewater containing starch granules. Indiscriminate discharge of this wastewater can pollute the environment, necessitating the use of wastewater treatment equipment.

[0003] After a period of use, the existing sedimentation tanks need to discharge sludge. However, the discharge of a large amount of sludge can easily cause blockages and affect the discharge efficiency. Therefore, a wastewater sedimentation tank for modified starch processing is needed. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater sedimentation tank for modified starch processing, which solves the problems mentioned in the background art.

[0005] This application provides a wastewater sedimentation tank for modified starch processing, including a tank body. A fixing frame and a discharge pipe are fixedly connected to the bottom end of the tank body. The discharge pipe is located on one side of the fixing frame. A motor is fixedly connected to the horizontal plate of the fixing frame. The motor is located below the discharge pipe. The output shaft of the motor passes through the interior of the discharge pipe and is fixedly connected to an auger. A slot is opened on the outer wall of the vertical tube of the discharge pipe. A sealing block is fitted inside the slot. A disassembly plate is fixedly connected to the outer wall of the sealing block. The disassembly plate abuts against the discharge pipe. A bolt passes through the disassembly plate and is threadedly connected to the discharge pipe. A vibration motor is fixedly connected to the horizontal tube of the discharge pipe.

[0006] In use, wastewater is first discharged into the tank through the wastewater inlet pipe. Then, an appropriate amount of flocculant is added into the tank through the flocculant dosing pipe to promote the reaction between the flocculant and the wastewater, reduce sludge settling time, and improve settling efficiency. When sludge needs to be discharged, the motor is started by the corresponding external power switch. The motor's output shaft drives the auger to rotate. The auger rotates to transport the sludge into the discharge pipe downwards. Because the discharge pipe is a curved design, the sludge transported to the bottom of the discharge pipe automatically slides out. Combined with the vibration motor, this can improve the sludge discharge efficiency. Furthermore, when the discharge pipe is blocked, the disassembly plate can be removed, and the sealing block can be removed from the inside of the tank opening for a quick small-scale cleaning of the inside of the discharge pipe to prevent sludge blockage.

[0007] Optionally, a sewage inlet pipe and a precipitant dosing pipe are fixedly connected to the top of the tank, with the precipitant dosing pipe located on one side of the sewage inlet pipe.

[0008] By adopting the above technical solution, it is beneficial to discharge wastewater and add precipitant.

[0009] Optionally, a guide bucket is fixedly connected inside the tank, and a connecting pipe is fixedly connected to the bottom end of the guide bucket. The connecting pipe is connected to the discharge pipe, and an electric valve is fixedly connected inside the connecting pipe.

[0010] By adopting the above technical solution, the guide bucket can prevent sludge and sewage from accumulating at the bottom of the tank, reducing the difficulty of subsequent cleaning.

[0011] Optionally, the discharge pipe is a bend.

[0012] By adopting the above technical solutions, it is beneficial to discharge sludge.

[0013] Optionally, the sealing block is made of rubber and is adapted to fit the groove.

[0014] By adopting the above technical solution, it is beneficial to improve the sealing effect of the groove.

[0015] Optionally, the spiral blades of the auger are spaced 2 mm apart from the inner wall of the vertical pipe of the discharge pipe.

[0016] By adopting the above technical solution, it is possible to prevent the spiral blades of the auger from colliding with the inner wall of the vertical pipe of the discharge pipe.

[0017] Optionally, the vertical cross-section of the fixing frame is an L-shaped structure.

[0018] By adopting the above technical solution, it is possible to install the motor below the discharge pipe.

[0019] Optionally, a total of four bolts are provided, and the four bolts are located at the four corners of the disassembly plate.

[0020] By adopting the above technical solution, the firmness of the connection between the disassembly plate and the discharge pipe is improved.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application uses the output shaft of the motor to drive the auger to rotate. The auger rotates on its own to transport the sludge into the discharge pipe downwards. Since the discharge pipe is a curved pipe design, the sludge transported to the bottom of the discharge pipe automatically slides out. With the help of the vibration motor, the discharge efficiency of the sludge can be improved. In addition, when the discharge pipe is blocked, the disassembly plate can be removed and the sealing block can be removed from the inside of the groove to quickly clean and unclog the inside of the discharge pipe in a small area, so as to avoid sludge blockage.
