[0002] An evaporative heater is a device used to convert a liquid medium (such as water) into steam. It is widely used in the chemical, pharmaceutical, and food processing industries. Currently, most evaporative heaters have a filtering effect, but when disassembling and assembling the filter, most of them are fixed with threads. If the connection is rusted, it is inconvenient to twist. At the same time, the traditional installation method is time-consuming and labor-intensive, and is not convenient for installation, which greatly reduces the disassembly and assembly progress of the staff and also greatly increases the workload of the staff. For this reason, a multi-channel heat exchange structure of an evaporative heater with filtering and stirring functions is proposed. Summary of the Invention

[0012] Furthermore, the stirring assembly includes: a motor, which is arranged at the end face of the evaporator heater body and has the same end face as the electric push rod; a reciprocating screw, which is horizontally arranged in the evaporator heater body and connected to the motor; two support plates, which are fixed on both sides of the evaporator heater body, and the two support plates are connected by a flow channel tube, and the piston is suitable for covering the end opening of the flow channel tube to form a sealing structure of the flow channel tube; a moving ring, which is threadedly engaged with the reciprocating screw; a plurality of connecting rods, whose ends are all connected to the moving rings, and the connecting rods all slide through the support plates; a plurality of stirring plates, which are fixed on the connecting rod along the axial direction of the connecting rod, wherein the flow channel tube passes through the stirring plates.

[0013] The present invention has the following beneficial effects:

[0014] (1) The present invention sets a filter assembly. Specifically, when the limit rod is inserted, the movable bracket needs to be pushed backward and the first spring will be squeezed. After the limit rod is inserted, the limit balls are acted upon by the force to move away from each other and embed into the limit frame. At this time, when the movable bracket is released, the block is reset together and the limit ball is limited. At the same time, the limit ball limits the limit rod. The rapid disassembly and assembly of the filter greatly improves the disassembly and assembly progress of the staff and greatly reduces the workload of the staff. At the same time, the timely replacement of the filter greatly improves the filtering effect of the equipment and greatly improves the heat exchange effect.

[0015] (2) The present invention sets an adjustment component, specifically, the knob is turned to drive the shaft to rotate, and when the shaft rotates, it will also drive the second limit bracket to rotate together. Then, the support rod rotates through the second limit bracket to pull the movable tube body to move. Since a plurality of openings are provided inside the fixed tube body, the opening area increases or decreases when the movable tube body is pulled, thereby adjusting the flow rate of the liquid that needs to be heat exchanged. By adjusting the flow rate of the liquid that needs to be heat exchanged, the pressure of the medium in the heater can be adjusted to a certain extent. In an emergency, the medium supply can be cut off more effectively and quickly, thereby avoiding damage to the equipment due to overload or failure. At the same time, the electric push rod is started to drive the piston to seal and circulate the circulation pipe, and the heating time of the circulating liquid is adjusted, which greatly improves the heat exchange effect. The movable tube body avoids unsatisfactory heat exchange caused by excessive or insufficient liquid flow rate, further improving the heat exchange effect.

[0016] (3) The present invention provides a stirring assembly, specifically, a starting motor drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the moving ring to move back and forth on the outside thereof. When the moving ring moves, it drives the stirring plate to move together through the connecting rod. When the stirring plate moves, it stirs the liquid for heat exchange inside the evaporating heater body, and also scrapes off impurities on the outer surface of the flow channel tube, making the heat exchange effect more uniform. At the same time, it also greatly reduces the adhesion of impurities on the outer wall of the flow channel tube, and greatly reduces the corrosion of the flow channel tube.

When the rotating shaft rotates, the second limit bracket will also be driven to rotate. The support rod will pull the movable tube body to move through the rotation of the second limit bracket. Since a number of openings are provided inside the fixed tube body, the opening area increases or decreases when the movable tube body is pulled, thereby adjusting the flow rate of the liquid to be heat exchanged. At the same time, the electric push rod is started to drive the piston to seal and circulate the circulation pipe, thereby adjusting the heating time of the circulating liquid, greatly improving the heat exchange effect, and the movable tube body avoids unsatisfactory heat exchange caused by excessive or insufficient liquid flow rate, thereby further improving the heat exchange effect.

The outer surface of the sliding rod 323 is slidably connected to the bottom of the right side of the inside of the evaporator heater body 111.

[0039] The stirring assembly 4 includes a motor 411, the left side of the motor 411 is fixedly connected to the right side of the evaporation heater body 111, the right side of the interior of the evaporation heater body 111 is rotatably connected to a reciprocating screw rod 415, the left output end of the motor 411 is fixedly connected to the right side of the reciprocating screw rod 415 through a coupling, the left and right sides of the interior of the evaporation heater body 111 are fixedly connected to support plates 412, a number of flow channel tubes 413 are fixedly connected to the inside of the two support plates 412, a moving ring 416 is provided on the right side of the support plate 412 on the right side, the interior of the moving ring 416 is threadedly connected to the outer surface of the reciprocating screw rod 415, a number of connecting rods 414 are fixedly connected to the left side of the moving ring 416, the outer surfaces of the several connecting rods 414 are slidably connected to the inside of the support plate 412 on the right side, and the several connecting rods 414 are fixedly connected to the left side of the moving ring 416. The left and right sides of the outer surface of the rod 414 are fixedly connected with stirring plates 417, and the interiors of the two stirring plates 417 are slidingly connected to the outer surface of the flow channel tube 413. The starting motor 411 drives the reciprocating screw 415 to rotate. When the reciprocating screw 415 rotates, it drives the moving ring 416 to reciprocate left and right outside it. When the moving ring 416 moves, it drives the stirring plates 417 to move together through the connecting rod 414. When the stirring plates 417 move, they stir the liquid for heat exchange inside the evaporating heater body 111, and also scrape off impurities on the outer surface of the flow channel tube 413, making the heat exchange effect more uniform, and at the same time greatly reducing the adhesion of impurities on the outer wall of the flow channel tube 413, greatly reducing the corrosion of the flow channel tube 413.

[0040] When in use, first add the heated liquid into the interior of the evaporative heater body 111 through the feed port 112, and then add the liquid that needs to be heat exchanged into the interior of the evaporative heater body 111 through the first connecting pipe 115. When the liquid that needs to be heat exchanged flows through the interior of the first connecting pipe 115, it needs to be filtered. The installation of the filter screen 214 is specifically as follows: first pick up the handle 213 and insert the filter screen 214 into the positioning groove 215. The function of the positioning groove 215 is to facilitate the positioning and installation of the filter screen 214, and at the same time position the filter screen 214. The groove 215 is fixedly connected to the first support frame 211, so the positioning groove 215 plays a certain supporting role on the filter 214 through the first support frame 211. When the filter 214 is inserted into the positioning groove 215, the limiting rod 217 is inserted into the limiting frame 218. When the limiting rod 217 is inserted, the movable bracket 222 needs to be pushed backward. When the movable bracket 222 is pushed, the stopper 221 will move together. At the same time, the stopper 221 will be limited by the limiting frame 218 and move toward the movable bracket 222. 22 slides inside and squeezes the second spring 225. When the movable bracket 222 is moved, it slides on the outer surface of the support rod 224. At the same time, when the movable bracket 222 moves, it squeezes the first spring 223. The first spring 223 is limited by the fixed plate 219 and shrinks. At this time, the limiting rod 217 is inserted into the limiting frame 218 to generate a force on the limiting ball 220. The limiting balls 220 are moved away from each other and embedded in the limiting frame 218 under the force. At this time, when the movable bracket 222 is released, At this time, the movable bracket 222 will be reset by the rebound force of the first spring 223. When the movable bracket 222 is reset, it will drive the stopper 221 to move and reset together. When the stopper 221 is reset, it will limit the limiting ball 220. At the same time, the limiting ball 220 limits the limiting rod 217, thereby completing the fixed installation of the filter 214. At the same time, when disassembling, it is only necessary to move the movable bracket 222 to drive the stopper 221 away from the limiting ball 220 to remove the limiting rod 217 and remove the filter 214 at the same time.

[0041] At the same time, the staff can also adjust the flow rate of the hot liquid that needs heat exchange by turning the knob 312. Specifically, turning the knob 312 drives the rotating shaft 313 to rotate. When the rotating shaft 313 rotates, it will rotate inside the second support frame 311, and when the rotating shaft 313 rotates, it will also drive the second limiting bracket 318 to rotate together. Then, the support rod 317 rotates through the second limiting bracket 318 to pull the limiting bracket 316 to move. At this time, the movable tube body 315 will also move together through the movement of the limiting bracket 316 and slide inside the fixed tube body 314. Since a number of openings are opened inside the fixed tube body 314, the opening area is increased or decreased by pulling the movable tube body 315, thereby adjusting the flow rate of the liquid that needs to be heat exchanged.

[0042] At the same time, the electric push rod 319 is started to drive the telescopic rod 320 to move. When the telescopic rod 320 moves, it slides inside the evaporation heater body 111. When the telescopic rod 320 moves, it drives the sealing ring 321 to move together. At this time, the movement of the sealing ring 321 drives the piston 322 to move. At the same time, when the piston 322 moves, the flow channel tube 413 is sealed and circulated. When the sealing ring 321 moves, it drives the sliding rod 323 to slide inside the evaporation heater body 111. When the liquid that needs to be heat exchanged flows into the evaporation heater body 111, the motor 411 is started to drive the reciprocating screw rod 415 to rotate. When the reciprocating screw rod 415 rotates, it drives the moving rod 323 to slide inside the evaporation heater body 111. The moving ring 416 performs reciprocating motion left and right on its outside. When the moving ring 416 moves, it will drive the connecting rod 414 to move together and slide inside the support plate 412 on the right side. When the connecting rod 414 moves, it will drive the stirring plate 417 to move together and slide on the outer surface of the flow channel tube 413. When the stirring plate 417 moves, it will stir the liquid undergoing heat exchange inside the evaporation heater body 111. At the same time, since the stirring plate 417 is slidably set on the flow channel tube 413, the stirring plate 417 will also scrape off impurities on the outer surface of the flow channel tube 413. After the heat exchange is completed, the liquid is discharged from the second connecting pipe 116, and the heated liquid is discharged from the discharge port 114.
