Description

Technical Field

[0001] This utility model relates to the field of sugarcane processing technology, specifically to a device for recycling waste liquid from sugarcane processing. Background Technology

[0002] During the sugarcane processing, a large amount of wastewater is generated from processes such as sugarcane juice extraction, purification, evaporation, crystallization, separation, and drying. This wastewater mainly comes from the condensate of evaporation tanks and sugar boiling tanks, as well as the washing water of various tanks. The waste liquid mainly comes from the sugarcane sugar production process. Although these waste liquids are not very toxic, they are highly organic waste liquids, and direct discharge will pollute water bodies and soil.

[0003] Flocculants play an important role in the treatment of sucrose processing wastewater, mainly by removing suspended solids and colloidal substances from the wastewater through coagulation and sedimentation. In the existing technology, when the wastewater treatment equipment extracts the clear water after the upper sedimentation, it is easy to extract the sediment at the bottom along with the clear water. Therefore, a wastewater recycling device for sucrose processing is proposed. Utility Model Content

[0004] This invention proposes a waste liquid recycling device for sugarcane processing, which solves the problem in related technologies where the sediment at the bottom is easily extracted with clean water.

A lifting assembly and a conveying assembly are respectively installed on the top of the sedimentation tank. The output end of the conveying assembly is connected to the water collection plate through a corrugated pipe.

[0010] Preferably, the conveying assembly includes a housing and a second pump body. The housing is located at the top of the sedimentation tank, and the second pump body is located on one side of the housing. The output end of the second pump body is connected to the water collection plate through a corrugated pipe.

[0011] Preferably, the lifting assembly includes a motor, a worm gear, and a worm wheel. The motor is located at the top of the sedimentation tank, and the output end of the motor is fixedly connected to the worm gear. The worm wheel is rotatably connected to the top of the sedimentation tank, and the worm gear and the worm wheel are meshed together. The worm wheel is threadedly connected to the threaded rod.

[0012] Preferably, a second motor is fixedly installed on the top of the mixing tank, and a stirring shaft is fixedly connected to the output end of the second motor through the mixing tank. Stirring rods are fixedly installed on the outer side wall of the stirring shaft.

[0013] Preferably, an inlet pipe is fixedly installed on the outer wall of the mixing tank, and a valve is installed on the outer wall of the inlet pipe.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. The system consists of a mixing tank, a pump, a sedimentation tank, and a filter plate. Flocculant is added to the mixing tank and mixed with the waste liquid. The pump then pumps the waste liquid from the mixing tank into the sedimentation tank for sedimentation. The clean water is located above the filter plate, and the sediment is located below the filter plate. This prevents the sediment from being drawn out along with the clean water due to the action of the filter plate.

[0018] 2. Through the set conveying component, lifting component, water collection plate and cleaning pipe, the conveying component delivers water to the water collection plate through the corrugated pipe. The water is sprayed out through the cleaning pipe. The lifting component, together with the threaded rod, drives the water collection plate to move downward. The water collection plate drives the cleaning pipe to insert into the filter hole of the filter plate to clean the sediment, thereby avoiding the sediment from clogging the filter plate and making it unusable.
