DETAILED DESCRIPTION

[0026] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model.

[0027] As Figures 1-3 shown, one embodiment of the utility model proposes a branch-like feeding structure, which comprises:

[0028] The tank body 1 comprises the bottom tank 101, the intermediate tank 102 and the top tank 103, the bottom tank 101, the intermediate tank 102 and the top tank 103 are connected with each other through flanges, the lower feeding pipe 104 is constructed on the bottom tank 101, the upper feeding pipe 105 is constructed on the top tank 103, the aeration pipe 2 is installed through the bottom tank 101, the bottom tank 101, the intermediate tank 102 and the top tank 103 are connected through the flange plate and the bolt, which can conveniently split the tank body 1 into three parts, so that the interior of the equipment can be cleaned regularly, and the convenience of the device is increased;

[0029] The heat exchange part 3 comprises a top plate 301 and a bottom plate 302 installed in the intermediate tank 102, a heating cavity 303 is arranged between the top plate 301 and the bottom plate 302, a plurality of heat exchange pipes 304 located in the heating cavity 303 are arranged in array between the top plate 301 and the bottom plate 302, and two water passing pipes 305 are arranged outside the intermediate tank 102 and communicated with the heating cavity 303. The heat exchange part 3 is arranged in the intermediate tank 102, and the heat exchange pipes 304 are vertically arranged, so that the liquid material flows from the top tank 103 into the bottom tank 101 through the heat exchange pipes 304. The liquid material can be preliminarily heated in this process, and then heated and evaporated by the temperature in the bottom tank 101, so as to realize evaporation and separation of impurities. The liquid level of the liquid material is always in the middle part of the heat exchange pipes 304, so as to be heated better.

[0030] The feeding mechanism 4 comprises a partition plate 401 arranged in the top tank 103, a feeding cavity 402 is arranged between the partition plate 401 and the top tank 103, a plurality of discharge vertical pipes 403 are arranged in array at the bottom of the partition plate 401 and communicated with the feeding cavity 402, and a pressure telescopic pipe 404 is arranged on each discharge vertical pipe 403 and used for spraying the liquid material into the heat exchange pipe 304. It should be noted that the pressure telescopic pipe 404 can move up and down on the discharge vertical pipe 403, and can also store and release pressure. The pressure telescopic pipe 404 is inserted into the heat exchange pipe 304 by telescopic movement, and then the pressure is released, so that the liquid material directly passes through the inlet end of the heat exchange pipe 304 without contacting the heat exchange pipe 304, thereby avoiding the scaling phenomenon of the inlet end of the heat exchange pipe 304 and preventing the heat exchange pipe 304 from being blocked. The telescopic movement of the pressure telescopic pipe 404 can also move the inlet end of the heat exchange pipe 304 in and out, so as to remove the accidentally scaled part of the inlet end of the heat exchange pipe 304 and further avoid the blockage. The regular feeding of the feeding mechanism 4 can effectively automatically clean the scaling of the inlet end of the heat exchange pipe 304, ensure the smooth flow of the liquid material, and increase the safety.

[0031] As shown in Figures 1-3 some embodiments, an upper ring plate 1021 and a lower ring plate 1022 are arranged on the inner wall of the intermediate tank 102, the inner diameter of the upper ring plate 1021 is greater than the inner diameter of the lower ring plate 1022, the outer diameter of the top plate 301 is greater than the outer diameter of the bottom plate 302, and the top plate 301 and the bottom plate 302 abut on the upper ring plate 1021 and the lower ring plate 1022, respectively. When it is necessary to clean the inner wall of the tank body 1, the bottom tank 101, the intermediate tank 102 and the top tank 103 need to be separated, and the top plate 301 and the bottom plate 302 are sequentially installed on the upper ring plate 1021 and the lower ring plate 1022. The top plate 301, the bottom plate 302 and the heat exchange pipes 304 can be pulled out from the upper side of the upper ring plate 1021, so as to clean the heat exchange pipes 304 and the top plate 301 and the bottom plate 302. The disassembly is more scattered, the personnel operation is facilitated, and the convenience of the device is increased.

[0032] AsFigure 5 As shown, in some embodiments, the aeration pipe 2 includes a main flow pipe 201 that penetrates and is installed inside the bottom tank 101. Multiple branch pipes 202 are arrayed on both sides of the main flow pipe 201, and multiple jet holes 203 are arrayed on the upper side of the branch pipes 202. By installing the aeration pipe 2 inside the bottom tank 101 and configuring it as a main flow pipe 201 and multiple branch pipes 202, gas can be dispersed and sprayed into the liquid, thereby ensuring the crystal precipitation efficiency in the liquid. Figure 6 As shown, in some embodiments, the pressure telescopic tube 404 includes an extension tube 4041 slidably inserted into the discharge vertical tube 403. A support spring 4042 sleeved on the extension tube 4041 is connected between the upper end of the extension tube 4041 and the bottom end of the discharge vertical tube 403. A piston ring 4043 is connected to the upper end of the extension tube 4041, and a pressure valve plate 4044 is constructed inside the piston ring 4043. It should be noted that the pressure valve plate 4044 is used as a valve body. When the pressure in the feed chamber 402 does not reach the critical point, the pressure valve plate 4044 closes. At this time, the pressure of the liquid will push the piston ring 4043 downward, thereby pushing the extension tube 4041 to extend inside the discharge vertical pipe 403, so that the extension tube 4041 is gradually inserted into the heat exchange tube 304, cleaning the inlet end of the heat exchange tube 304 to avoid blockage. When the pressure is greater than the critical point, the pressure valve plate 4044 opens, and the liquid will quickly rush into the heat exchange tube 304, preventing the liquid from being in contact with the inlet end of the heat exchange tube 304 for a long time, reducing the possibility of scaling, further reducing the possibility of blockage, and increasing safety.

[0033] like Figure 6 As shown, in some embodiments, the pressure valve plate 4044 includes four sector-shaped plates 40441 constructed on the inner wall of the piston ring 4043, and a cross gap 40442 is constructed between the four sector-shaped plates 40441. When the pressure in the feed chamber 402 is insufficient, the cross gap 40442 is closed, and the four sector-shaped plates 40441 abut against each other to form a blockage. When the pressure is sufficient, the cross gap 40442 opens, and the four sector-shaped plates 40441 flip over, thereby allowing the liquid to flow out.

[0034] like Figure 6 As shown, in some embodiments, the bottom end of the extension tube 4041 is constructed with an expanding conical ring 40411. The diameter of the expanding conical ring 40411 is smaller than the inner diameter of the heat exchange tube 304. The lower end of the expanding conical ring 40411 is constructed with an angled surface, which allows it to be better inserted into the heat exchange tube 304. This allows for impact cleaning of scale at the port of the heat exchange tube 304. At the same time, when the extension tube 4041 contracts, the conical surface can be used to rub and clean the inner wall of the heat exchange tube 304, thereby improving the cleaning effect.

[0035] like Figures 3-4As shown in the drawings, in some embodiments, the gas collection jet 5 is also included, which comprises a hollow circular frame 501 mounted on the top plate 301, and a plurality of insertion pipes 502 inserted into the heat exchange pipe 304 are arranged at the bottom side of the hollow circular frame 501, and a jet cavity 503 in communication with the hollow circular frame 501 is arranged in the inner wall of the insertion pipe 502, and a plurality of jet pipes 504 located in the heat exchange pipe 304 are arranged at the bottom end of the insertion pipe 502. By injecting gas into the hollow circular frame 501, the insertion pipe 502 can be used to jet the inner wall of the heat exchange pipe 304, and in cooperation with the high temperature of the heat exchange pipe 304 itself, the scale on the inner wall of the heat exchange pipe 304 can be softened and cleaned to some extent, thereby reducing the wall thickness of the heat exchange pipe 304 and ensuring the heat exchange efficiency.

[0036] As shown in the drawings, Figure 3 In some embodiments, the bottom side of the hollow circular frame 501 is provided with an air inlet pipe 505 penetrating through the top plate 301 and the bottom plate 302, and the diameter of the air inlet pipe 505 is much larger than the diameter of the heat exchange pipe 304. The air inlet pipe 505 is connected in the bottom tank 101, so that the gas can be collected when the aeration pipe 2 is working, and the gas is re-pressurized into the heat exchange pipe 304 by pressure, thereby realizing the cleaning of the inner wall of the heat exchange pipe 304, without the need for additional air pressure supplement, thereby saving resources.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
