Slow agitating magnetic suspension liquid storage box

Abstract

The invention relates to a slow agitating magnetic suspension liquid storage box, which is characterized in that a speed reduction motor is adopted to provide a power for an agitating device; the speed reduction motor is fixed on a cover plate by four supporting pillars; a vertical shaft of an agitator is connected with a power output shaft of the speed reduction motor through a shaft coupler; a long brush made of a soft material is arranged at the lower part of the agitator; brush fur at the lower end of the long brush sticks to the bottom of a liquid storage barrel; a liquid outlet of the liquid storage barrel is arranged at the bottom of the barrel, and the liquid outlet is communicated with a liquid pumping and draining pump through a connecting pipe; a liquid injection valve and a liquid drainage valve are respectively arranged on a drainage outlet branch of the liquid pumping and draining pump; a liquid level sensor is also arranged on a pipeline of the connecting pipe; and a liquid level signal of the liquid level sensor is transmitted to a display screen or an executing electrical appliance through a conducting wire, so that a liquid level quantity value is displayed in real time or an acousto-optic informing signal is sent. Due to adoption of the technical scheme in the invention, uniform and consistent concentration of the magnetic suspension liquid within a period from a starting time to a stopping time in a fault detection process can be guaranteed; a liquid quantity and a consumption quantity of the magnetic suspension liquid can be monitored in real time; and liquid changing is easy and convenient.

Description

technical field [0001] The invention relates to a wet method magnetic powder flaw detection equipment, in particular to a slow stirring magnetic suspension liquid storage tank. Background technique [0002] During the operation of wet magnetic particle flaw detection, it is necessary to apply magnetic particle suspension mixed with magnetic powder and carrier liquid to the parts to be detected. Therefore, the magnetic suspension liquid storage tank is an essential functional part of wet magnetic particle flaw detection equipment, and this part is widely used at present. (1) Uneven stirring of the magnetic suspension, (2) Troublesome operation to replace the expired magnetic suspension, (3) Inaccurate measurement of the magnetic suspension liquid in the storage tank, etc., especially in automatic flaw detection, the above shortcomings are appear more prominent; [0003] Analysis of the reasons for the above shortcomings: [0004] (1) The magnetic suspension is not stirred e...

AI Technical Summary

Problems solved by technology

[0006] Since the specific gravity of the magnetic powder is greater than that of the carrier liquid, it is necessary to continuously stir to produce the magnetic powder suspension. The magnetic suspension liquid storage tanks in the prior art generally adopt methods such as rapid rotation of small blades or reflux stirring of the liquid pump. These stirring methods are all Partial stirring can also make the carrier liquid generate vortex flow, but due to the large area of ​​the bottom of the tank, it is impossible for the flowing carrier liquid to quickly stir all the deposited magnetic powder in a short time, and even a few hours of stirring can not reach the specified magnetic suspension. At this time, the operator often uses the method of adding more magnetic powder to solve the problem of insufficient concentration, which brings about the instability of the concentration of the magnetic suspension. The concentration is very weak at the beginning of stirring, and it will take tens of minutes or even longer , the concentration may be too thick, which will seriously affect the actual use of flaw detection equipment;

[0007] (2) It is troublesome to replace the expired magnetic suspension

[0008] The magnetic suspension liquid storage tanks in the prior art all use a built-in liquid pump to extract the magnetic suspension liquid. Most of the magnetic particle inspection equipment is designed to be beautiful as a whole, and the liquid storage tank is often designed as a built-in type. The entire liquid storage tank is added The weight of the upper magnetic suspension is at least 40kg. In this way, if you need to replace the magnetic suspension, you must move it out, disassemble the pump and the tank cover, and then remove the liquid storage tank for cleaning. It takes time and effort to replace the new magnetic suspension. , the labor intensity is very high;

[0009] (3) The amount of magnetic suspension liquid in the liquid storage tank is not accurately measured

[0010] The magnetic suspension in the liquid storage tank will be consumed after repeated use. The magnetic particle flaw detection equipment in the prior art adopts manual application of the magnetic suspension. When the magnetic suspension is consumed, it can be found in time and added in time; if this If the liquid storage tank is installed on the automatic magnetic particle flaw detection equipment, accidents without magnetic suspension liquid flaw detection may occur; moreover, since there is no liquid volume display, it is difficult to grasp the amount of magnetic powder to be added when adding magnetic powder and carrier liquid in proportion
