[0026] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] In an exemplary embodiment, as shown in Figures 2-6 The embodiment provides a horizontal heat exchange system, which comprises a horizontal heat exchange box 1, a plurality of installation frames 25 are arranged on the top surface of the heat exchange box 1 from one end to the other end in the length direction, each installation frame 25 is installed with a cover plate 2, the cover plate 2 is further fixedly connected with a plurality of heat exchange plates 3 which extend vertically into the heat exchange box 1 and are arranged side by side in sequence, the heat exchange plate 3 is provided with a cavity 4, the cavities 4 of the heat exchange plates 3 connected on the same cover plate 2 are sequentially communicated through a connecting pipe 5, the cover plate 2 is further fixedly connected with a liquid inlet pipe 6 and a liquid outlet pipe 7 which are located outside the heat exchange box 1 and respectively communicate with the heat exchange plates 3 at the head and tail; the heat exchange box 1 is further fixedly connected with a feed pipe 8 and a discharge pipe 9 which are located at both ends of the heat exchange box 1, and all the heat exchange plates 3 are located between the feed pipe 8 and the discharge pipe 9; the heat exchange plate 3 is further provided with a plurality of heat exchange channels 10 which penetrate through both surfaces of the heat exchange plate 3; the heat exchange channel 10 is further provided with a flow resistance member which reduces the flow speed of liquid material passing through the heat exchange channel 10.

[0029] In the above embodiment, a completely different idea from the prior art is adopted, the heat exchange medium is provided to flow through the detachable heat exchange plates 3, the heat exchange medium enters the cavities 4, the liquid material in the heat exchange box 1 exchanges heat with the heat exchange medium in the cavities 4 through the heat exchange plates 3, and the heat exchange purpose is achieved. After a period of time, the heat exchange plates 3 can be directly taken out through the cover plate 2 for targeted cleaning, thereby improving the cleaning efficiency and avoiding the occurrence of cleaning dead angles, solving the problem that the internal components of the heat exchanger in the prior art are not easy to clean thoroughly. Further, the cover plate 2 and the heat exchange box 1 can be connected in a conventional manner, such as bolt connection. More specifically, the cover plate 2 is further fixedly connected with a connecting frame 11 surrounding all the heat exchange plates 3 outside the cover plate 2, the connecting frame 11 abuts against the heat exchange box 1, and a sealing gasket 12 is further arranged between the connecting frame 11 and the heat exchange box 1. Correspondingly, a step abutting against the connecting frame 11 is arranged in the mounting frame 25, the sealing gasket 12 is clamped between the connecting frame 11 and the inner wall of the mounting frame 25, and the sealing effect is achieved. At the same time, this does not affect the smooth disassembly and assembly, and further, the sealing gasket 12 can be arranged in a structure of thin at the bottom and thick at the top. In this way, when the cover plate 2 is installed, the sealing ring is sleeved outside the connecting frame 11, and then placed into the mounting frame 25 downward, and finally fastened by bolts. The sealing gasket 12 arranged can be slightly larger, so that the sealing gasket ring is in a compressed state after fastening, and a better sealing effect is achieved. When disassembled, the bolts are loosened, and then the cover plate 2 is lifted upward. In particular, the step arranged in the present scheme can provide upward lifting for the cover plate 2, which helps to improve the connection stability of the cover plate 2. Further, a plurality of supporting blocks 13 can be arranged at the end of the heat exchange plate 3 away from the cover plate 2. The supporting blocks 13 abut against the inner bottom surface of the heat exchange box 1, and play a positioning role to assist the cover plate 2 to stably arrange the heat exchange plate 3 in the heat exchange box 1. In a more detailed scheme, a positioning head 14 can be fixedly arranged on the inner bottom surface of the heat exchange box 1, and a positioning groove for the positioning head 14 to abut into is correspondingly arranged on the supporting block 13, so that the positioning is more accurate, and the stability of the heat exchange plate 3 in the heat exchange box 1 is further improved, so that the system can operate normally for a long time. The supporting blocks 13 can also be provided for the liquid material to pass through.

[0030] In a further exemplary scheme, as Figures 5-6As shown, the flow blocking member includes a connecting rod 15 connected with the heat exchange channel 10 in an extendable manner, and a flow blocking plate 16 detachably connected with the connecting rod 15 towards one end of the feed pipe 8, and the flow blocking plate 16 is always away from the heat exchange plate 3, that is, there is a gap between the flow blocking plate 16 and the heat exchange channel 10, so that the liquid material can smoothly pass through the heat exchange channel 10, and the flow blocking plate 16 arranged can block the liquid material from directly entering the heat exchange channel 10, so that the liquid material needs to bypass the rear of the flow blocking plate 16 to enter the heat exchange channel 10, and a stagnation area will be generated behind the flow blocking plate 16, that is, the liquid material will backflow to this area, so that the liquid material entering the heat exchange channel 10 passes at a slow speed, and the heat exchange between the liquid material and the heat exchange channel 10 can be relatively more sufficient, the heat exchange efficiency is improved, and more liquid material will flow to the surrounding heat exchange channels 10 after the flow speed is reduced. In the present scheme, the feed pipe 8 is arranged at a lower position, and the heat exchange plate 3 and the flow blocking plate 16 arranged in this way can also guide the flow to make the excess liquid material flow upwards, so that the liquid material can pass through more heat exchange channels 10 at a relatively balanced speed, and it is not easy to pass through a small part of the heat exchange channels 10 at a too fast speed. Therefore, the utilization efficiency of the heat exchange plate 3 can be improved, and the heat exchange effect is better, and finally the liquid material is discharged through the discharge pipe 9 arranged at a higher position; More specifically, the side of the heat exchange plate 3 close to the feed pipe 8 is recessed and provided with a plurality of first grooves 17 corresponding to the heat exchange channels 10, one end of the heat exchange channel 10 is connected with the inner bottom surface of the corresponding first groove 17, and the flow blocking plate 16 is located in the first groove 17. The first groove 17 increases the surface area of the heat exchange plate 3, and the liquid material contacts the outer wall of the heat exchange plate 3 during the process of entering the heat exchange channel 10, and also enters the first groove 17 to contact the inner wall of the first groove 17, and then enters the heat exchange channel 10. Heat exchange can be carried out in the whole process; Further, the end of the connecting rod 15 away from the flow blocking plate 16 is also detachably connected with a flow dividing plate 18 (the flow dividing plate 18 and the flow blocking plate 16 can be threadedly connected, so that the disassembly can be smoothly carried out), and the flow dividing plate 18 is always away from the heat exchange plate 3. The flow dividing plate 18 makes the liquid material flow to the surrounding, and then enters the front of the next heat exchange plate 3, and a stagnation area also exists behind the flow dividing plate 18, so that the liquid material slows down; At the same time, the flow dividing plate 18 can also be arc-shaped, and the side of the heat exchange plate 3 away from the first groove 17 is recessed and provided with a plurality of second grooves 19 corresponding to the first grooves 17, one end of the heat exchange channel 10 away from the first groove 17 is connected with the inner bottom surface of the second groove 19, the flow dividing plate 18 is located in the second groove 19, and the flow dividing plate 18 is arc-shaped and the arc-shaped opening is the same as the opening of the second groove 19. The first groove 17 and the second groove 19 can be arc-shaped, which can increase the overall area of the heat exchange plate 3, and have a flow guiding effect on the liquid material, so that the liquid material smoothly flows through the inner walls of the first groove 17 and the second groove 19;

[0031] Furthermore, the connecting rod 15 is telescopic, and a fixed cylinder 20 is slidably sleeved on the outside of the connecting rod 15. The fixed cylinder 20 is fixedly connected to a threaded sleeve 22 via a fixed rod 21. The threaded sleeve 22 is threadedly connected to the inner wall of the heat exchange channel 10. A spring 23 is also sleeved on the outside of the connecting rod 15, located between the fixed cylinder 20 and the flow divider plate 18. With the assistance of the spring 23, the positions between the flow divider plate 18 and the flow baffle plate 16 can reach a balanced state, so that the flow rate of the liquid material through the heat exchange channel 10 can be kept constant. Specifically, when the flow rate in front of the heat exchange plate 3 increases (i.e., in front of the first groove 17), the pushing force on the flow baffle plate 16 will increase, thereby causing the flow baffle plate 16 to move towards the second groove 19, which in turn pushes the connecting rod 15 to stretch the spring 23, and the flow divider plate 18 moves away from the second groove 19. Thus, the flow rate entering the heat exchange channel 10 is reduced. As the flow rate increases, the flow rate of the liquid material entering the second groove 19 through the outlet channel also increases, meaning the liquid material enters and exits the heat exchange channel 10 faster. Conversely, the pushing force on the baffle plate 16 decreases, the tension of the spring 23 decreases, and the baffle plate 16 and the diverter plate 18 move in opposite directions. Although the distance behind the baffle plate 16 increases, the distance between the diverter plate 18 and the front decreases, so the liquid material enters and exits at a slower speed, thus adapting to liquid materials with various flow rates. Specifically, the fixed cylinder 20 provides a base for the sliding installation of the connecting rod 15, and the telescopic connection of the connecting rod 15 is realized with the assistance of the spring 23. At the same time, the setting of the screw sleeve 22 makes the connecting rod 15 detachable, and both the baffle plate 16 and the diverter plate 18 are detachable. During cleaning, they can be disassembled for more thorough cleaning and to prevent cleaning dead spots.

[0032] like Figure 4 As shown, in a further exemplary embodiment, a row of strip grooves 24 can be provided on both sides of the heat exchange plate 3. Multiple first grooves 17 or multiple second grooves 19 can be provided in a strip groove 24. The strip groove 24 can further increase the area of ​​the heat exchange plate 3 and improve the heat exchange efficiency.

[0033] Furthermore, in this scheme, the heat exchange plates 3 on each cover plate 2 are relatively independent, and independent heat exchange media are introduced and exported respectively. This allows each part of the heat exchange box 1 to circulate relatively independently. Compared with the prior art, where the heat exchange media at the rear is often affected by the front and heats up, this scheme will not. Lower temperature heat exchange media can be introduced to achieve better cooling effect (conversely, introducing higher temperature heat exchange media will achieve better heating effect).

[0034] Finally, it is to be explained that the above embodiments are only used to illustrate the technical solutions of the present application but not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
