Circulating water multifunctional solid dirt separator for fishpond

Abstract

The invention provides a multifunctional solid contaminant separator of the circulating water in a fishpond, which is composed of a case body, a mesh screen, a low-speed motor and a drainage system; the mesh screen is fixed in the center position inside the case body and consists of a cylindrical frame and a filter screen, the cylindrical frame is composed of a long plate bar and round rings that are welded together, the filter screen is inlaid and fixed outside the cylindrical frame; the low speed motor and the flushing device, the ozonizer pipeline and the suction pipe of the drainage system are arranged outside the case body; the ozonizer pipeline is connected with a shower pipe that is arranged in the case body and above the mesh screen; the suction pipe is accessed into the lower part inside the case body; the axial direction of the drainage pipe is at the central shaft of the mesh screen in the case body, a drainage bag is arranged above the drainage pipe in the mesh screen; the device is simple in structural design, low in cost and water-consuming rate, stable in mechanical property and is convenient for production management and maintenance, which is a practical device for the water treatment of plant-mode industrial culturing and can solve the solid contaminants in the circulating water so as to keep the clean water quality of the circulating water and lead the circulating water to be recycled.

Description

Technical field: [0001] The invention belongs to the industrial culture water treatment technology, and is a multifunctional solid dirt separator for circulating water in fish ponds. Background technique: [0002] Before the present invention was made, the separation method of the solid dirt particles in the water body of industrial farms at home and abroad: mainly rely on filter bags, sand filters and sedimentation methods; The larger particles (0.1um to 3.3μm) in the water body, the fine particles in the water body are difficult to absorb, and the filter bag has to be cleaned and replaced manually every day; the sand filter is equipped with a filter sand layer in the tank, and by retaining a certain amount of particles The diameter of the particles can achieve the purpose of removing particles. Since the flow rate of the water flow is in a state of gradually decreasing with the increase of the intercepted matter, it is necessary to adjust the flow rate valve at any time to...
