Secondary resettling device for heparin

Abstract

The invention discloses a heparin secondary re-sedimentation device in the field of biopharmaceuticals, which includes a tank body, a mud discharge pipe, a slant plate, a water inlet pipe, a water outlet pipe, a water outlet tank, a sludge return pipe and a mud collecting bucket, and an outlet end of the water inlet pipe. Located in the center of the pool body, the water inlet end of the water inlet pipe is located above the water outlet end, and the water outlet end of the water inlet pipe is connected to a bell mouth, and a horizontally placed reflector is hung just below the bell mouth, and slant plates are installed on both sides of the bottom of the pool body The sewage return pipe is provided at the inner wall of the sloping plate adjacent to one side, and the water inlet end of the water inlet pipe is connected with the water outlet end of the sewage treatment tank arranged outside the pool body; the two sloping plates at the bottom of the pool body are surrounded by A mud collecting hopper is formed, and the mud inlet end of the sludge return pipe is inserted into the mud collecting hopper; a mud discharge port is provided at the bottom of the pool body. The invention has the advantages of simple structure, low investment cost, small floor area and good sedimentation effect, especially can effectively intercept and separate suspended solids in sewage that are not easy to sediment, and is widely applicable to various waste water treatment systems that require high effluent water quality.

Description

technical field [0001] The invention relates to a heparin secondary re-precipitation device in the field of biopharmaceuticals. Background technique [0002] In 1904, Americans Hazen and Camp invented the shallow pond settlement theory. On this basis, they successively developed inclined plate sedimentation tanks, inclined tube sedimentation tanks, interception sedimentation tanks, advection sedimentation tanks, etc., but the current application in the field of water treatment is Sedimentation tanks have certain disadvantages to varying degrees: 1. The design focus on sediment separation and efficient sludge discharge is different, and the function is single. When the water volume and water quality change, the impact resistance is poor; 2. The water flows through the inclined plate or inclined pipe. During the process, because the water flow is rising and the sediment is falling, it will cause relative movement to the settled suspended solids, and the rising water will s...

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a high-efficiency sedimentation tank, which can solve the problems of traditional radial flow sedimentation tanks with large footprint, low impact resistance, and low volume utilization of the sedimentation tank. Disadvantages, it has the advantages of small space occupation and good effluent water quality, especially the effective removal of difficult-to-sediment suspended matter that is difficult to remove in traditional sedimentation tanks
