Detailed Embodiments

[0019] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present utility model as follows.

[0020] Referring to the above-mentioned attached Figures 1 - 3As shown in the figure, the internal circulation high-efficiency concentrator provided by the utility model includes a tank body 1. The upper end of the tank body 1 is provided with a feed pipe 2 and a steam outlet pipe 3, the lower part is provided with a discharge pipe 4 and a steam inlet pipe 5. The discharge pipe 4 is equipped with a discharge pump 6. Its characteristics are that: a liquid material pipeline is arranged in the tank body 1. The upper end of the liquid material pipeline is provided with a feed inlet 8 aligned with the lower end of the feed pipe 2. A water pump 9 is also arranged in the tank body 1. The outlet of the water pump 9 is connected with a circulation pipe 10 extending to the upper part of the tank body 1. The liquid material pipeline is a spiral pipe 7. The spiral pipe 7 spirals from the bottom of the tank body 1 to the upper part of the tank body 1. The lower end of the spiral pipe 7 is provided with a discharge port. The outer circle of the spiral pipe 7 is fixedly connected with the inner wall of the tank body 1, specifically by welding. The water pump 9 is arranged at the center of the bottom of the tank body 1 and is surrounded by the spiral pipe 7. The circulation pipe 10 extends above the spiral pipe 7, and the upper end of the circulation pipe 10 is provided with a liquid separation structure. The liquid separation structure is a water baffle 11. The water baffle 11 is connected with the upper end of the circulation pipe 10 through a plurality of support feet 12. The vertical section of the spiral pipe 7 is square, and a plurality of through holes 15 are arranged on the upper surface of the spiral pipe 7. The water pump 9 is a submersible pump, and the electric wire 16 of the water pump 9 passes through the tank body 1 and is connected with an external power supply.

[0021] In this embodiment, the liquid material flows into the liquid material pipeline through the feed inlet 8 and gradually flows to the bottom of the tank body 1. The liquid material at the bottom of the tank body 1 is pumped into the circulation pipe 10 by the water pump 9 and sprayed out from the outlet of the circulation pipe 10 at the upper part of the tank body 1, so that the liquid material reaches internal circulation in the tank body 1. The overall structure is simple and compact, and at the same time, the volume is smaller, greatly reducing the occupied space and reducing the production cost at the same time; part of the liquid material sprayed out from the outlet of the circulation pipe 10 flows into the liquid material pipeline through the feed inlet 8, and the other part splashes onto the inner wall of the tank body 1 and the outer surface of the liquid material pipeline and flows down to form a liquid film, with a larger contact area and longer contact time with the steam, improving the concentration efficiency; the liquid material pipeline is a spiral pipe 7, increasing the flow time of the liquid material in the pipeline and having a longer contact time with the steam. The outer circle of the spiral pipe 7 is fixedly connected with the inner wall of the tank body 1, and the structure is more stable and firm; the water pump 9 is arranged at the center of the bottom of the tank body 1 and is surrounded by the spiral pipe 7. When working, it cooperates with the circulation pipe 10 and the water baffle 11 to make the liquid material spray out more dispersedly, further increasing the contact area and contact time between the liquid material and the steam, and being more conducive to the concentration work; when too much initial liquid material enters the liquid material pipeline from the feed pipe 2, the through holes 15 serve as overflow holes. During the subsequent circulation process, when there is not much liquid material in the liquid material pipeline, the liquid material sprayed out from the circulation pipe 10 can flow into the liquid material pipeline through the through holes 15, and the steam can also enter the liquid material pipeline through the through holes 15, and the structure is reasonable and multi-functional.

[0022] Refer to Figure 4 As shown in the figure, it is the second embodiment of the liquid separator in the utility model. The liquid separation structure is a rotary spray head 13 (the rotary spray head 13 belongs to the prior art, and how it rotates specifically will not be elaborated here). A plurality of nozzles 14 are equally divided and arranged on the outer circle of the rotary spray head 13.

[0023] In this embodiment, when the water pump 9 is working, the liquid material enters the circulation pipe 10, the rotary nozzle 13 and is ejected through the nozzle 14. During the ejection process of the liquid material, the rotary nozzle 13 is driven to rotate, so that the liquid material is ejected more dispersedly, increasing the contact area and contact time between the liquid material and the steam, which is more conducive to the concentration work.

[0024] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
