Aquaculture wastewater treatment device

Abstract

The invention discloses an aquaculture wastewater treatment device which comprises an auger type solid-liquid separation device. An intelligent power distribution box is fixedly installed on the right end face of the auger type solid-liquid separation device; a speed reducer located at the top of the intelligent power distribution box is fixedly installed on the right side face of the intelligent power distribution box; and a driving motor is fixedly installed at the right end of the speed reducer; Through cooperation of a base, a force storage device and a release device, a pushing device does shear type opening motion, and it is ensured that the pushing device cannot make contact with a small amount of solid matter newly accumulated below an extrusion opening in the reset process. Through cooperation of the intelligent power distribution box, a strain device and a trigger device, transmission between a transmission device and the auger type solid-liquid separation device is cut off. Through cooperation of the base and the force storage device, the pushing device does a shear type closing action and moves rightwards, it is ensured that the pushing device can be reset and make preparation for the next action, and the practicability of the aquaculture wastewater treatment device is improved.

Description

technical field [0001] The invention relates to the field of animal husbandry, and more specifically, relates to a breeding wastewater treatment device. Background technique [0002] With the development of animal husbandry, industrial competition is becoming increasingly fierce, and the large-scale and intensive development of animal husbandry has become an inevitable trend. Large-scale breeding has high feeding technology and unified management, which reduces costs and improves economic benefits. The problem of environmental pollution caused by a large amount of concentrated excrement flushing and sewage discharge is becoming more and more serious. The excrement and waste water of the aquaculture industry contain a large amount of organic matter, nitrogen, phosphorus, suspended solids and pathogenic bacteria and produce foul odors, which are directly discharged into Rivers or surface water will seriously pollute the water source and soil environment, destroy the original f...

[0002] With the development of animal husbandry, industrial competition is becoming increasingly fierce, and the large-scale and intensive development of animal husbandry has become an inevitable trend. Large-scale breeding has high feeding technology and unified management, which reduces costs and improves economic benefits. The problem of environmental pollution caused by a large amount of concentrated excrement flushing and sewage discharge is becoming more and more serious. The excrement and waste water of the aquaculture industry contain a large amount of organic matter, nitrogen, phosphorus, suspended solids and pathogenic bacteria and produce foul odors, which are directly discharged into Rivers or surface water will seriously pollute the water source and soil environment, destroy the original function of the water body, endanger human health and agricultural and fishery production, such as eutrophication, and cause fatal damage to the water quality of the water area. Therefore, comprehensive treatment of wastewater by enterprises is a must This is a far-sighted sustainable development strategy decision, and will make a great contribution to protecting the water environment, reducing pollution, and maintaining ecological balance. The difficulty of wastewater treatment in farms is the treatment of NH3-N and excrement, and the focus is on the pre-biochemical Solid-liquid separation work, which is done by solid-liquid separation equipment

[0003] When the existing solid-liquid separation equipment is in use, firstly, the non-clogging submerged pump supporting the solid-liquid separation equipment lifts the livestock and poultry manure water into the solid-liquid separation equipment, and then the auger gradually pushes the manure water to the bottom of the machine. At the front, at the same time, the pressure at the front edge of the machine is continuously increased, forcing the moisture in the material to squeeze out of the screen under the action of the side pressure belt filter and discharged through the drain pipe, and then the feces are continuously lifted into the body of the solid-liquid separation equipment. The pressure continues to increase, and when the pressure reaches a certain level, the discharge port will be opened, and then the dehydrated solids will be squeezed out of the extrusion port to achieve the purpose of extrusion, but the extruded solid matter will It is directly stacked under the discharge port. With the passage of time, more and more solid objects are accumulated under the discharge port. It is necessary to manually monitor the accumulation of solid materials. Use a shovel to remove the solid matter accumulated under the discharge port, resulting in a large workload for the workers, time-consuming and laborious, so it is urgent to design a breeding wastewater treatment device
