Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, and particularly to a high-efficiency quick oil-removing cleaning agent for heat exchangers and its processing equipment. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in many industrial productions such as chemical industry, petroleum, power, food and others. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. At present, dirt and impurities often appear when heat exchangers are in use, and cleaning agents need to be used regularly for cleaning to facilitate the better use of heat exchangers.

[0003] At present, stirring devices are often used in the manufacturing process of cleaning agents to mix various raw materials, effectively ensuring the normal performance of the cleaning agent. However, during the stirring process of the current stirring devices, the raw materials often accumulate at the bottom, which will lead to insufficient mixing of the materials, affect the performance of the cleaning agent, and thus reduce the stirring efficiency.

[0004] Therefore, we have proposed a high-efficiency quick oil-removing cleaning agent for heat exchangers and its processing equipment to solve the above problems. Summary of the Invention

[0046] A method for using an apparatus as above, the steps including:

[0047] S1. Add all the raw materials of the cleaning agent to the stirring device in sequence, and turn on the power supply of the stirring device;

[0048] S2. The stirring shaft starts to rotate, driving the stirring rod 1 to stir the raw materials;

[0049] S3. And the delay mechanism 2 is powered on, driving the conductive mechanism 3 to move outward, making the extrusion mechanism 4 intermittently powered on and off, continuously repeating the extrusion of the raw materials at the bottom of the stirring device, so that they roll upward under the action of hydrodynamic force, promoting further mixing of the materials;

[0051] Working principle: When using this stirring device, power on the device. The stirring rod 1 will drive the rotation under the action of the stirring motor. At the same time, since the conductive block 32 and the conductive plate 34 are electrically connected, the electromagnet 25 and the electromagnetic block 41 are both in the powered-on state and generate magnetism at this time. At this time, the conductive block 32 will be subjected to the repulsive force of the magnetism of the electromagnet 25 and the magnetic column 33. Since the magnetic repulsive force is greater than the elastic force of the second spring 31, the conductive block 32 extends downward, maintaining the process that the bottom of the conductive block 32 is always in contact with the top of the conductive plate 34. And the damping block 24 is subjected to the attractive force of the magnetism of the electromagnet 25 and the iron block 21. Since the suction force is greater than the elastic force of the first spring 23, and since the viscosity of the magnetorheological fluid increases under the magnetic action, the difficulty of the magnetorheological fluid passing through the damping hole 26 increases, so the damping block 24 will slowly move inward, effectively extending the power-on time of the electromagnetic block 41 and the electromagnet 25;

[0052] Meanwhile, the electromagnetic block 41 and the magnetic block 46 in the simultaneous extrusion mechanism 4 repel each other, and the acting force is greater than the elastic force of the third spring 44. Therefore, the piston block 45 will move downward to squeeze the liquid downward. According to fluid mechanics, the raw materials at the bottom will be pushed by the extruded raw materials, causing the raw materials at the bottom to roll upward, effectively solving the problem of raw material accumulation at the bottom and improving the mixing efficiency.
