Abstract
The utility model relates to an ultrasonic cleaning device of a nuclear power station main pump. The device comprises a pot body, an ultrasonic wave oscillating box, an ultrasonic generator, a recirculating pump, a blower, a spray nozzle ring canal, a sealing ring board and an air duct, and is characterized in that the ultrasonic wave oscillating box is fixed on the pot body and connected with the ultrasonic generator through radio cables, the air duct and the spray nozzle ring canal are fixed in the pot body, the lower end of the air duct is led to the outside part of the pot body and connected with the blower, the inlet of the recirculating pump is communicated with the bottom of the pot body, the outlet of the recirculating pump is communicated with the spray nozzle ring canal, and the sealing ring board is fixed on the pot body through bolts. In the utility model, because the main pump to be cleaned is placed in a sealed space, soaked in the pyrochemistry solution, and circularly washed, the contaminants are further left and dispersed by utilizing the ultrasonic wave, and the pot body is pumped to subpressure, the device can efficiently remove stains, do not damage the surface of the device, and effectively protect the staff.
Description
Technical field
The utility model relates to ultrasonic cleaning equipment, is a kind of nuclear power station main pump ultrasonic cleaning equipment specifically.
Background technology
Before maintenance nuclear power station main pump hydraulic part, need clean it, make it to reach the maintenance safety requirement.Existing cleaning way is such as utilizing high-temperature high pressure water flushing, acid-base solution soaking flushing, or artificial clean etc., not only danger but also bother, and on cleaning performance and scavenging period, all can not satisfy maintenance requirement to the main pump hydraulic part.Therefore, design and a kind ofly can effectively remove main pump hydraulic part surface radioactive pollution, can guarantee that again the nuclear power station main pump ultrasonic cleaning equipment of maintainer's safety is very necessary.
Summary of the invention
The purpose of this utility model provides a kind ofly can effectively remove main pump hydraulic part surface radioactive pollution, can guarantee the nuclear power station main pump ultrasonic cleaning equipment of maintainer's safety again.
For achieving the above object, the utility model adopts following technical scheme: a kind of nuclear power station main pump ultrasonic cleaning equipment, comprise tank body, top cover, ultrasonic wave Vibration Box retaining mechanism, ultrasonic wave side Vibration Box, Vibration Box at the bottom of the ultrasonic wave, supersonic generator, electric heater for pipeline, circulating pump, measuring tank, blower fan, motor-driven valve, switch board, the top nozzle endless tube, following nozzle endless tube, the sealing ring flat-plate, airduct, sample valve, airduct converges mouth, Vibration Box is fixed on the tank body by ultrasonic wave Vibration Box retaining mechanism at the bottom of it is characterized in that ultrasonic wave side Vibration Box and ultrasonic wave, Vibration Box is connected with supersonic generator by high frequency cable at the bottom of ultrasonic wave side Vibration Box and the ultrasonic wave, supersonic generator is connected with switch board by the control cable, airduct and top nozzle endless tube, following nozzle endless tube is fixed in the tank body, the airduct lower end causes the tank body outside and converges a mouthful import with airduct and link to each other, the outlet that airduct converges mouth is connected with blower fan, inlet of circulating pump is communicated with the bottom of tank body by pipeline, outlet of circulating pump is communicated with top nozzle endless tube and following nozzle endless tube respectively by pipeline, on the pipeline of supreme nozzle endless tube of outlet of circulating pump and following nozzle endless tube, sample valve is set, electric heater for pipeline and measuring tank, the sealing ring flat-plate is by being bolted on the tank body, the top of tank body is provided with liquid injection port, and the bottom of tank body is provided with leakage fluid dram.
During the utility model work, hang out top cover, main pump to be cleaned is winched on the tank body, make the main pump hydraulic part be arranged in main pump, sealing ring flat-plate and the formed seal cavity of tank body.Utilize the immersion dissolution of high temeperature chemistry solution to carry out preliminary decontamination earlier, in this process, solution is carried out inner loop with circulating pump, the flushing of realization top nozzle, following nozzle stirs flushing, carrying out the solution concentration sampling by sample valve simultaneously detects, and utilize measuring tank to carry out the Configuration Online dosing, guarantee that solution concentration satisfies cleaning requirement.Airduct, airduct converge mouthful and blower fan will be pumped into negative pressure in the tank body, have guaranteed issuablely in immersion process to contain active steam and do not overflow, and avoid occurring internal irradiation hazard.When solution temperature is reduced to ultrasonic wave proper operation temperature, utilize " cavitation " of ultrasonic wave in solution that the pollutant in main pump surface and the slit is peeled off dispersion again, further decontamination.After cleaning is finished, hang away main pump, cover top cover.The utility model is efficient, low to be arranged, and harmless to equipment surface, and can effectively protect staff's safety.
