Abstract
The invention discloses a dual-pump circulating stirring dispensing process and belongs to the field of dispensing in sewage treatment. The dual-pump circulating stirring dispensing process is characterized by including the steps that tap water and coagulants used for sewage treatment are simultaneously added into a dispensing tank, and water is added and stopped until the water level is leveled to a level sensor; an electromagnetic valve A is opened, a plastic pump is started, supernatant in the dispensing tank enters an upper suction pipe, solid particles at the bottom of the dispensing tank are sucked into a lower suction pipe, fluid in the upper suction pipe and in the lower suction pipe enters the dispensing tank together by passing through a plastic pump suction pipe, the plastic pump, a stirring pipe and a stirring nozzle, and circulating fluid enters the dispensing tank to enable the fluid in the tank to rotate so as to stir the coagulants; after the coagulants are dissolved sufficiently, the electromagnetic valve A is closed, and an electromagnetic valve B is opened to enable chemical liquor to enter a chemical liquor storage tank for standby; and when a required unit of sewage treatment facilities needs the chemical liquor, a metering pump is started, and the chemical liquor is delivered to the required unit of the sewage treatment facilities through a metering pump outlet pipe. The dual-pump circulating stirring dispensing process has the advantages of less equipment investment, simple structure, less proneness to blockage, pump overload prevention and easiness in maintenance and replacement.
Description
technical field [0001] The double-port parallel pump circulation stirring dispensing process of the present invention relates to the technical field of pump circulation stirring medicine dispensing. Background technique [0002] The mixing and dispensing method of the agitator driven by the variable speed of the motor that is generally sold on the market and is being used in general sewage stations. [0003] The mixing form is mainly composed of a stirring motor, a high transmission ratio reducer, a mixing blade, a dispensing tank, a support stand, etc. The high transmission ratio reducer generally adopts a cycloidal pinwheel reducer, which has a complex structure and high manufacturing precision requirements , high cost, difficult maintenance, and high technical requirements for maintenance workers. Generally, when this kind of reducer fails, it will be replaced with a new one, resulting in high maintenance and repair costs. [0004] For a long time, the rated power of the...
