[0013] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Potassium chloride and sodium chloride salt separation evaporator flash feeding device, such as Figure 1 As shown, it includes a box body 1 and a preheating box 2. The box body 1 and the preheating box 2 are matched together, and the upper and lower ends of the box body 1 pass through the upper and lower ends of the preheating box 2 respectively. The top of the box body 1 is connected to the feed pipe, and the bottom of the box body 1 is connected to the discharge pipe. A regulating mechanism is movably installed in the box body 1, and a pushing mechanism is movably installed at the bottom of the box body 1. One side of the top of the preheating box 2 is fixedly connected to the air inlet pipe, and the other side of the bottom of the preheating box 2 is fixedly connected to the air outlet pipe. Steam enters the preheating box 2 from the air inlet pipe, and the hot steam stays in the preheating box 2 to preheat the material in the box body 1, so that the material passing through the box body 1 is preheated to improve production efficiency. The material enters the box body 1 from the feed pipe, and the speed or amount of the material falling downward is controlled by the regulating mechanism to avoid accumulation of the material in the next process, and the material at the bottom of the box body 1 can be pushed toward the discharge pipe by the pushing mechanism to avoid accumulation in the corner of the box body 1, and the pushing mechanism also prevents the material from adhering to the inner wall of the bottom end of the box body 1 to prevent residue.

[0015] Specifically, the control mechanism described in this embodiment includes movable plates 3 hingedly installed on the inner walls of both sides of the box body 1, a slide groove 4 is provided at the bottom end of the movable plates 3, a slider 5 which is always moved in the slide groove 4 is slidably installed in the slide groove 4, and first telescopic rods 6 are fixedly installed on the inner walls of both sides of the box body 1, and the movable end of the first telescopic rod 6 is movably connected with the slider. The extension directions of the two first telescopic rods 6 are opposite, and the first telescopic rods 6 are extended or contracted, so that the slider 5 can move in the slide groove 4, and the movable plates 3 are controlled to be folded around the connection point with the inner wall of the box body as the center, and the distance between the opposite ends of the two movable plates 3 is adjusted. The larger the distance between the opposite ends of the two movable plates 3, the more materials can pass through, and the smaller the distance between the opposite ends of the two movable plates 3, the flow rate and quantity of the materials can be controlled, and the adjustment can be made at any time according to the production situation of the next process to meet the production requirements.

[0016] Furthermore, the pushing mechanism described in this embodiment includes second telescopic rods 8 respectively fixedly mounted on the inner walls of both sides of the box body 1, and the opposite ends of the movable ends of the two second telescopic rods 8 are respectively fixedly mounted with vertical plates 9, and the bottom ends of the vertical plates 9 are in contact with the inner wall of the bottom end of the box body 1. The two second telescopic rods 8 are extended to push the two vertical plates 9 to move relative to each other, and the materials at the bottom end of the box body 1 are pushed into the discharge pipe. At the same time, the bottom ends of the vertical plates 9 are in contact with the inner wall of the bottom end of the box body 1, and the materials adhering to the bottom end of the box body 1 can be scraped off. When there is too much material in the next process, the distance between the opposite ends of the two movable plates becomes smaller, so that the amount of material passing through is reduced. At this time, the part of the material at the bottom end of the box body 1 is pushed by the two vertical plates 9 to move the materials remaining in the box body 1 out of the box body, and the material can also be continuously fed. When the material consumption of the next process is about to end, the distance between the opposite ends of the two movable plates in the regulating mechanism begins to adjust the distance according to demand to meet the production needs.

[0017] Furthermore, the top of the vertical plate 9 described in this embodiment is provided with an inclined plate 7. The two inclined plates 7 are inclined in opposite directions, and the two inclined plates 7 can prevent materials from falling into the space between the vertical plate 9 and the inner wall of the side end of the box body, thereby preventing residues from being generated.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
