Description

Technical Field

[0001] The utility model relates to the technical field of chemical cooling devices, in particular to a cooling device for chemical use. Background Art

[0002] Chemical industry involves the process of converting raw materials into more valuable products through chemical reactions or physical treatments. Among them, cooling devices are an indispensable part of the chemical production process. They are mainly used to reduce the temperature of materials during chemical reactions, ensure that reaction conditions are controlled, and improve production efficiency and safety. The cooling devices currently used in the chemical production process include tubular coolers, plate coolers and cooling towers. Tubular coolers are common heat exchange equipment. Fluid flows in the tube, while another fluid passes outside the tube or in the shell to achieve the purpose of heat transfer.

[0003] When the existing tubular cooler is in use, the hot fluid to be exchanged enters the heat exchange tubes through the head. Since there are generally multiple heat exchange tubes, each heat exchange tube is fed with hot fluid from the head, but the external hot fluid is only sent into the head through a single pipeline, and the heat exchange tubes installed in the shell are high and low, so that the hot fluid can only pass through the upper heat exchange tube after the head is filled, which makes the overall heat exchange efficiency low. Secondly, a large amount of hot fluid is at the bottom. If it is a viscous fluid, it will easily produce deposition and solidification. Utility Model Content

[0004] The purpose of the utility model is to provide a cooling device for chemical industry to solve the above-mentioned deficiencies in the technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a cooling device for chemical industry, comprising:

[0007] The stirring assembly includes a stirring hopper and a circular plate. The stirring hopper is attached to the inner wall of the first head. The circular plate is rotatably connected to the inside of the stirring hopper. A plurality of material holes are opened on the circular plate, and a plurality of material guide plates with different directions are connected to one end of the circular plate facing the feed port of the first head.

[0008] Preferably, an annular slide bar is fixed on the outer circumference of the circular plate, an annular slide groove is provided on the inner wall of the mixing hopper, and the annular slide bar is slidably matched with the annular slide groove.

[0009] Preferably, a plurality of balls are rollingly mounted on the outer wall of the annular slide bar, and the balls contact the inner wall of the annular slide groove.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] The utility model sets a stirring component. When the hot fluid enters the stirring hopper, the hot fluid will impact the guide plate on the circular plate. The circular plate can be rotated inside the stirring hopper by sliding the annular slide bar in the annular slide groove.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Figure 1 This is the appearance diagram of the utility model, and combined with Figure 2 As shown, the chemical cooling device includes a cooler body 1, a coolant inlet pipe 6 is connected to one end of the lower end surface of the cooler body 1, and a coolant outlet pipe 7 is connected to the other end of the upper end surface of the cooler body 1, and a heat exchange tube 10 is installed inside the cooler body 1 along the length direction, and a plurality of heat exchange tubes 10 are provided, and the heat exchange tubes 10 are used to pass the hot fluid to be exchanged, and spoilers 11 staggeredly distributed up and down are provided inside the cooler body 1 and outside the heat exchange tubes 10. There are a plurality of spoilers 11, and the spoilers 11 are used to guide the shell-side fluid to flow along a predetermined path to increase the turbulence and improve the heat transfer efficiency, and a first head 2 and a second head 3 are symmetrically installed at both ends of the cooler body 1 through flanges, a feed pipe 4 is connected to the first head 2, and a discharge pipe 5 is connected to the second head 3, and a stirring component is provided inside the first head 2, and the stirring component is used to stir the hot fluid passing into the first head 2.

[0026] Among them, see Figure 3-Figure 4 As shown, the stirring assembly includes a stirring hopper 12 and a circular plate 13. The stirring hopper 12 is attached to the inner wall of the first head 2. The circular plate 13 is rotatably connected to the inside of the stirring hopper 12. A plurality of material holes 17 are opened on the circular plate 13. The material holes 17 are used for the passage of hot fluid. A plurality of guide plates 14 are connected to one end of the circular plate 13 facing the feed port of the first head 2. The orientations of the guide plates 14 are different, which can disrupt the flow direction of the hot fluid and thereby increase the degree of turbulence.

[0027] Second, see Figure 4 As shown, an annular slide bar 15 is fixed on the outer circumference of the circular plate 13 , an annular slide groove 18 is provided on the inner wall of the mixing hopper 12 , and the annular slide bar 15 is slidably matched in the annular slide groove 18 .

[0028] Through the above technical solution:

[0029] During specific use, first ensure that the coolant is passed into the cooler body 1 from the coolant inlet pipe 6, and the coolant after heat exchange flows out from the coolant outlet pipe 7. The coolant enters at a low level and exits at a high level to ensure that the cooler body 1 is filled with coolant. Then, the chemical hot fluid to be cooled can be passed from the feed pipe 4 into the first head 2, and enters the stirring hopper 12, and then enters the heat exchange tube 10. During the flow of the hot fluid in the heat exchange tube 10, heat is exchanged using the coolant filled in the cooler body 1, and the hot fluid after heat exchange and cooling can be discharged from the discharge pipe 5 on the second head 3.

[0030] When the hot fluid passes through the pipeline into the mixing hopper 12, the hot fluid will impact the guide plate 14 with different directions. The circular plate 13 can be rotated inside the mixing hopper 12 by sliding the annular slide bar 15 in the annular slide groove 18, and then the hot fluid inside the mixing hopper 12 can be stirred by the guide plate 14, so that the hot fluid can be turned inside the mixing hopper 12, thereby increasing the occurrence of the hot fluid passing through the upper end heat exchange tube 10, which can effectively improve the low heat exchange efficiency, and through automatic stirring, it can prevent the viscous fluid from being deposited and solidified at the bottom end of the first head 2. Improve fluidity.

[0031] Further, see Figure 4 As shown, a plurality of balls 16 are rollingly mounted on the outer wall of the annular slide bar 15 , and the balls 16 contact the inner wall of the annular slide groove 18 .

[0032] Specifically, the provided balls 16 can change the sliding friction into rolling friction, thereby reducing the friction force, which is beneficial to the rotation of the annular slide bar 15 in the annular slide groove 18 .

[0033] Also, see Figure 1 As shown, at least two mounting collars are sleeved on the outside of the cooler body 1, a support frame 8 is fixed on each mounting collar, a bottom end of the support frame 8 is connected to a mounting base plate 9, and a mounting hole is opened on the mounting base plate 9.

[0034] Through the above, the support frame 8 can be stably fixed by using the mounting base plate 9 with mounting holes, thereby ensuring the stability of the cooling device after installation.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
