It has excellent chemical stability, lubricity, and insulating properties. It is not easily oxidized or volatile, and is non-irritating to human skin.

[0003] At present, in the existing light liquid paraffin processing process, due to the differences in its raw material quality and purification process, the oil body contains certain impurities, especially the content of embryotoxic substances. The traditional processing technology has a relatively low efficiency in removing trace amounts of water-soluble impurities with embryotoxicity in the raw material light liquid paraffin. Therefore, there is an urgent need for a device for cleaning light liquid paraffin. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3A device for cleaning light liquid paraffin comprises a liquid dispensing tank body 1, a discharge pipe 6 is provided at the bottom of the liquid dispensing tank body 1, a middle side of the discharge pipe 6 is connected to a water phase circulation pipe 3, and the other end of the water phase circulation pipe 3 has a liquid outlet 31 extending into the top of the liquid dispensing tank body 1 and is fixed by a mounting bracket 8, a limiting cylinder 9 is provided in the middle of the mounting bracket 8, a filter cover 10 is clamped and installed at the bottom of the limiting cylinder 9, and a water phase circulation pipe 3 is passed through the limiting cylinder 9.

[0021] Furthermore, a plurality of electric stirring paddles 2 are installed at the bottom of the liquid preparation tank body 1 .

[0022] Furthermore, the middle portion of the water phase circulation pipe 3 is connected to the peristaltic pump 4 , and the material in the liquid preparation tank body 1 is pumped by the peristaltic pump 4 and circulated into the liquid preparation tank body 1 .

[0023] Furthermore, one end of the water phase circulation pipeline 3 and the discharge pipe 6 are respectively provided with an opening and closing valve 1 5 and an opening and closing valve 2 7.

[0024] Furthermore, a mounting bracket 8 is provided on the top of the liquid dispensing tank body 1, a groove is provided in the middle of the mounting bracket 8, a mounting cover 91 is embedded in the groove, the bottom of the mounting cover 91 is connected to a limiting cylinder 9, and a plurality of limiting grooves 92 are provided on the outer side of the bottom of the limiting cylinder 9, and a filter cover 10 is installed on one side of the limiting groove 92 by a convex limiting column 11.

[0025] Furthermore, a plurality of convex head limiting posts 11 are provided at the upper end of the filter cover 10 , and a convex head is provided at the top end of the convex head limiting posts 11 .

[0026] In this embodiment, the water phase liquid for cleaning is poured into the liquid preparation tank body 1, and then light liquid paraffin is added. The upper layer in the tank body is the oil phase 13, and the lower layer is the water phase 14. At this time, the liquid outlet 31 of the water phase circulation pipe 3 is immersed 1-2 cm below the liquid level of the oil phase 13. Manually close the opening and closing valve 2 7 at the discharge pipe 6 at the bottom of the tank, open the opening and closing valve 1 5, turn on the electric stirring paddle 2 and the peristaltic pump 4. At this time, the water phase 14 in the lower layer of the liquid preparation tank body 1 is in a circulation state, and the material enters the water phase circulation pipe 3 connected to the discharge pipe 6 and under the action of the peristaltic pump 4, passes through the outlet The liquid port 31 continuously outputs the water phase 14 into the tank body. At this time, with the help of the electric stirring paddle 2, the liquid in the tank is in a slightly rotating state. The water phase 14 liquid enters the rotating oil phase 13 to increase the contact with the oil phase 13. The precursor water phase 14 sinks to the bottom and starts a new cycle. After stirring for a certain period of time, it is allowed to stand. After the oil phase 13 and the water phase 14 are completely separated, the bottom water phase 14 is discharged through the discharge port 12 of the liquid outlet pipe. Then, the on-off valve 1 5 at the water phase circulation pipeline 3 is closed, and the on-off valve 2 7 is opened. The cleaned oil phase 13 is led out through the discharge pipe 6 by compressed air.

[0027] Among them, during actual use, when the water phase circulation pipe 3 circulates the liquid through the liquid outlet 31, the material contacts the filter cover 10 set at the bottom of the limiting cylinder 9 and is preliminarily filtered, and common compound impurities in the material are preliminarily filtered. After long-term use, by rotating the filter cover 10, the convex head limiting column 11 on the filter cover 10 is disengaged from the limiting groove 92 set at the bottom of the limiting cylinder 9.

[0028] Among them, a circular through hole is opened at one end of the slot of the limiting groove 92, which fits with the convex head limiting column 11. When the convex head limiting column 11 is inserted into the through hole through its convex head, the limiting column completes the initial connection with the limiting groove 92. At this time, the filter cover 10 is rotated so that the convex head limiting column 11 is completely stuck in the limiting groove 92, and due to the setting of the convex head to prevent it from detaching from the limiting groove 92, this is easy to understand intuitively and will not be elaborated here.

[0029] In the utility model, a plurality of electric stirring paddles 2 arranged in the liquid preparation tank body 1 can keep the light liquid paraffin and the water phase 14 liquid rotating at a slow speed, and circulate the water phase 14 under the action of the water phase circulation pipe 3 and pass through the rotating oil phase 13 to increase the contact between the water phase 14 and the oil phase 13. After sufficient circulation, the oil phase 13 and the water phase 14 are completely separated by standing. After the water phase 14 is emptied, the cleaned light liquid paraffin is sent out through the discharge pipe 6. In the circulation process, the filter cover 10 arranged at the bottom of the limiting cylinder 9 can effectively screen out the compound impurities in the material, effectively improve the cleaning effect of the material, and ensure the processing efficiency.

[0030] At the same time, after long-term use, the filter cover 10 can be disassembled into the limiting cylinder 9 by rotating it. The process is convenient and fast, and the processing efficiency is effectively guaranteed.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
