Anti-corrosion treatment device and method for interior of shell of liquid turbine flowmeter

Abstract

The invention discloses an anti-corrosion treatment device and method for the interior of a shell of a liquid turbine flowmeter, and belongs to the technical field of chemical instruments. The anti-corrosion treatment device comprises a base, wherein a treatment table is fixedly connected to the top of the base, a fixing frame is fixedly connected to the inner wall of the top of the treatment table, and bearing seats are fixedly connected to the two sides of the bottom of the fixing frame; a lead screw is transversely arranged at the opposite sides of the two sets of bearing seats, threads opposite in rotating direction are arranged on the outer walls of the two sides of the lead screw respectively, supporting blocks are connected to the outer walls of the two sides of the lead screw in athreaded manner respectively, and during air exhaust, a disc is driven by a motor to rotate, an air intake cover can move up and down in a reciprocating manner, so that the waste gas suction range ofthe air intake cover can be enlarged, and therefore the waste gas treatment efficiency is improved; and meanwhile, a blade can be driven to rotate while the air intake cover moves in a reciprocating manner, and air flowing around the motor can be accelerated through rotation of the blade below the motor, so that the effect of assisting in cooling of the motor can be achieved, and the service lifeof the motor is prolonged.

Description

Technical field[0001]The invention relates to the technical field of chemical instrumentation, in particular to an anticorrosive treatment device and method inside a housing of a liquid turbine flowmeter.Background technique[0002]Liquid turbine flowmeter is a precision flow measuring instrument, which can be used to measure the flow and total amount of liquid when matched with the corresponding flow totalizer. Liquid turbine flowmeters are widely used in metering and control systems in the fields of petroleum, chemical industry, metallurgy, scientific research, etc. The liquid turbine flowmeter equipped with sanitary joints can be used in the pharmaceutical industry. The housing of the liquid turbine flowmeter includes a straight pipe. Both ends of the straight pipe are integrally formed with flanges, and the middle of the straight pipe is cast with radial protrusions. In order to improve the service life of the liquid turbine flowmeter, the inside of the shell needs to be treated w...

Problems solved by technology

[0003] The purpose of the present invention is to provide an anti-corrosion treatment device and method for the interior of the liquid turbine flowmeter housing, so as to solve the problem in the above-mentioned background technology that at present, the interior of the housing is usually sprayed with manual hand-held spray guns, and the anti-corrosion treatment of the interior of the housing is solved. The treatment efficiency is low, and the painting effect is not good, and the exhaust gas generated during painting will also cause great damage to the respiratory tract of the person holding the spray gun
