Description

Technical Field

[0001] This invention relates to the field of hazardous waste treatment, and more particularly to a viscous waste liquid feeding system. Background Technology

[0002] Viscous waste liquid feeding systems often employ simple manual or semi-automatic methods. For example, materials are manually poured into a pit and then fed to a solid material feeding system via a grab bucket. This method carries significant safety risks, easily leading to pit combustion and fires. Alternatively, after the supernatant is extracted, the residue in the tonne container is crushed along with the container and fed into the pit, then grabbed and fed. This crushing process can easily ignite, causing a fire. These systems are cumbersome to operate, labor-intensive, and difficult to precisely control the feed rate and volume of waste liquid, resulting in low processing efficiency, high safety risks, uneven equipment load, and waste liquid overflow pollution. This poses a serious threat to workers, equipment, and the environment. Existing feeding systems are inadequate in fire prevention, explosion protection, and emergency response, and their safety protection capabilities need improvement. Particulate matter and gel-like substances in viscous waste liquid easily deposit in feed pipes and processing devices, causing equipment blockages and affecting the normal operation of the system.

[0003] In addition, due to its high viscosity and low fluidity, viscous waste liquid is prone to causing blockages in the feeding system, which are difficult to clean. This places high demands on the conveying capacity, anti-blocking performance, and precise control of the feeding amount and speed of the feeding system. Summary of the Invention

[0093] In one preferred embodiment, the viscous waste liquid feeding system can be controlled locally by a PLC and remotely controlled by a host computer in the central control room.

[0094] The working methods of Examples 1 and 2 are as follows:

[0095] In use, the feed bucket 12 to be processed is placed into the elevator 11. The elevator 11 can lift the feed bucket 12 to the upper part of the hopper 22 and rotate the feed bucket 12 to a greater than 135° angle to facilitate the pouring of the viscous waste liquid remaining at the bottom of the bucket into the hopper 22. After the viscous waste liquid is poured out, the conveyor motor 1113 rotates in the opposite direction, rotates the feed bucket 12 in the opposite direction and lowers it to the initial position. After the feed bucket 12 is removed, the next feed bucket 12 can be put into the elevator 11 for the next cycle operation. The viscous waste liquid passes through the upper filter screen of the silo filter 23 with a pore size of 30mm, which intercepts large solid particles in the viscous waste liquid. It then passes through the lower filter screen with a pore size of 10mm, which intercepts solid particles larger than 10mm. After passing through the silo filter 23, the viscous waste liquid enters the double-helix blade mixer 24. The double-helix blades stir the viscous waste liquid, ensuring it is evenly mixed, preventing solidification and clumping. The mixture is then propelled by the blades through the silo filter 23 and the double-helix blade mixer 24. The helical blades of the mixer 24 transport the viscous waste liquid to the press 34. The press 34, through the reciprocating motion of the piston rod of the hydraulic cylinder, squeezes the viscous waste liquid into the cavity of the waste liquid pump 35. Through the reciprocating pushing action of the cylinder inside the waste liquid pump 35, the waste liquid is pumped through the pipeline into the waste liquid spray gun 4, and then enters the rotary kiln for incineration through the waste liquid spray gun 4. An automatic shut-off valve is installed between the pipeline 36 and the feed inlet 41 to perform emergency shut-off in case of backfire.

[0096] The mixing system for viscous waste liquid feed utilizes a mixer design to generate pressure that helps overcome the problems of high viscosity and poor flowability of the waste liquid. This enhances mixing, reduces the risk of blockage, ensures smooth entry of the waste liquid into the pump, lowers equipment failure rates, extends equipment lifespan, and guarantees stable system operation. The waste liquid spray gun design, with its cleaning hydraulic cylinder, effectively removes residue from the spray gun's feed channel, preventing backfire. It also enables refined feeding and multi-frequency feeding modes, reducing idle time, lowering energy consumption, maximizing equipment processing capacity, and improving both resource utilization efficiency and safety in waste liquid treatment. The addition of a shut-off valve allows for rapid closure after feeding stops, effectively preventing backflow, leakage, or accidental combustion during non-operational periods, reducing safety hazards. It also facilitates equipment maintenance, cleaning, and component replacement, improving maintenance efficiency. This invention effectively solves the problems of difficult feeding control, high safety risks, and easy blockage in traditional viscous waste liquid treatment, significantly improving waste liquid treatment efficiency, equipment stability, and safety. It provides strong support for achieving resource recovery, volume reduction, and harmless treatment of waste liquid.
