Description

Technical Field

[0001] This utility model relates to the technical field of chemical discharge devices, specifically a continuous cooling and transfer device for chloroalkanes. Background Technology

[0002] Chlorinated alkanes are indispensable reagents in organic experiments. They can be used as organic solvents, intermediates in pharmaceuticals and pesticides, and raw materials for the production of catalysts in the synthetic rubber industry. They are a product series with a wide range of applications. Industrially, they are obtained by directly chlorinating alcohols and hydrochloric acid. After the reaction is completed, the material is usually transferred intermittently, which has certain instability and safety hazards. Furthermore, the intermittent transfer increases the workload of workers.

[0003] Existing patent document CN220048089U discloses a continuous cooling and transfer device for chloroalkanes, comprising a reactor. A conveying pipe is embedded in the bottom of the reactor, and a control valve is fixedly installed at the other end of the conveying pipe. A fluid input pipe is fixedly installed at the other end of the control valve. The end of the fluid input pipe opposite to the control valve is connected to a hollow heat exchange chamber. A Tesla valve conduit is fixedly installed inside the hollow heat exchange chamber. A fluid output pipe is embedded in the side of the Tesla valve conduit opposite to the fluid input pipe, and the other end of the fluid output pipe is connected to a storage tank. This invention allows the liquid chloroalkanes to undergo multiple sets of repetitive deceleration movements inside the Tesla valve conduit, thereby ensuring that the high-temperature liquid chloroalkanes have sufficient residence time inside the Tesla valve conduit. Since the Tesla valve conduit is located inside the hollow heat exchange chamber, it can exchange heat with the internal heat exchange medium for a longer time, resulting in better heat exchange efficiency.

[0004] Although the device has many beneficial effects, the following problems still exist: When dealing with chloroalkanes that are prone to crystallization or contain impurities, the Tesla valve conduit of the device is prone to scaling and blockage inside the flow channel, especially in dead corners. This not only drastically reduces the heat exchange efficiency, but also makes cleaning and maintenance extremely difficult, often requiring shutdown and disassembly of a large number of parts, affecting the continuity of production.

[0005] Secondly, the pipes and heat exchange units of this device are connected by flange bolts, which makes the disassembly process cumbersome, time-consuming and labor-intensive. In chemical production environments where frequent cleaning or replacement of parts is required, this connection method greatly increases the labor intensity of workers and the downtime of equipment.

[0048] This utility model provides an overall structural schematic diagram of an embodiment of a continuous cooling and transfer device for chloroalkanes, including:

[0049] Please see Figures 1-6 The continuous cooling and transfer device for chloroalkanes according to this embodiment includes: a feed pipe 2 installed on the outer wall of the reaction vessel 1;

[0050] Multiple conveying pipes 3, one end of some conveying pipes 3 is installed on the side wall of the reactor 1, a control valve 4 is installed in the middle section of some conveying pipes 3, and a storage tank 6 is installed at one end of another conveying pipe 3.

[0051] Multiple mounting bases 5, some mounting bases 5 are located at the other end of a portion of the conveying pipe 3, and other mounting bases 5 are located at the other end of another portion of the conveying pipe 3;

[0052] Multiple docking mechanisms 100 are provided, with some docking mechanisms 100 located between a portion of the conveying pipe 3 and a portion of the mounting base 5, and another portion of docking mechanisms 100 located between another portion of the conveying pipe 3 and another portion of the mounting base 5, which can quickly dock the conveying pipe 3 and the mounting base 5.

[0053] The heat exchange mechanism 200 is located between one part of the mounting base 5 and another part of the mounting base 5. It can reduce the temperature while reducing the transport speed of chloroalkanes and protecting the internal structure.

[0054] It is worth noting that, in order to connect the conveying pipe 3 and the mounting base 5, specifically, the connecting mechanism 100 includes: a limiting ring a101 welded to the outer periphery of the conveying pipe 3;

[0055] The sliding collar 102 is slidably connected to the outer periphery of the limiting ring a101. A limiting groove a103 is provided at one end of the inner wall of the sliding collar 102. The limiting ring a101 is slidably connected to the inner wall of the limiting groove a103, and the sliding collar 102 can move and rotate.

[0056] Sealing plate 104 is welded to the side wall of mounting base 5;

[0057] Multiple sliding grooves a105 are formed on the outer periphery of the mounting base 5. Damping spring shock absorbers 106 are welded to the bottom of the multiple sliding grooves a105. Limiting blocks 107 are welded to the outer ends of the multiple damping spring shock absorbers 106. Multiple limiting grooves b108 are formed on the other end of the inner wall of the sliding collar 102. The limiting block 107 and the limiting groove b108 are mortised and tenoned together to fix the sliding collar 102. At this time, the inner wall of the limiting groove a103 contacts the limiting ring a101, which can connect the conveying pipe 3 and the mounting base 5.

[0058] The docking groove 109 is formed on the side wall of the conveying pipe 3. The docking groove 109 and the sealing plate 104 are connected by tenon and tenon joints, which can seal the conveying pipe 3 and the mounting base 5.

[0059] Next, in order to fix the sliding collar 102, specifically, the limiting block 107 is made in the shape of a spherical crown, with the straight surface of the spherical crown opened on the inner side of the limiting block 107, and the outer side of the inner wall of the limiting groove b108 is opened as a straight surface, which can prevent the limiting block 107 and the limiting groove b108 from separating due to the relative sliding of the sliding collar 102 and the mounting base 5.

[0060] Meanwhile, in order to cool down, specifically, the heat exchange mechanism 200 includes: a heat exchange chamber 201 installed between a portion of the mounting base 5 and another portion of the mounting base 5; a water inlet 202 is opened on one side wall of the heat exchange chamber 201; a water outlet 203 is opened on the other side wall of the heat exchange chamber 201; and a heat exchange tube 204 is welded to the inner wall of the heat exchange chamber 201, which can cool down the material inside the heat exchange tube 204.

[0061] The support base 205 is welded to the inner wall of the heat exchange tube 204. The side wall of the support base 205 is rotatably connected to the bearing 206, which can support the rotating shaft 207.

[0062] One end of the rotating shaft 207 is rotatably connected to the side wall of the bearing 206. A spiral blade 208 is welded to the outer circumference of the rotating shaft 207. A toothed groove 209 is opened at the outer end of the spiral blade 208. A turbine blade 210 is welded to the other end of the rotating shaft 207. When the material impacts the turbine blade 210, the kinetic energy of the material can be converted into the rotational kinetic energy of the rotating shaft 207. While decelerating the material, the rotating shaft 207 can be rotated. The toothed groove 209 can make the material flow through the inner wall of the heat exchange tube 204 in a concentrated manner, thus cleaning the inner wall of the heat exchange tube 204.

[0063] Furthermore, in order to clean the inner wall of the heat exchange tube 204, specifically, the outer end of the spiral blade 208 contacts the inner wall of the heat exchange tube 204, which can clean the inner wall of the heat exchange tube 204.

[0064] It is worth noting that, in order to control the material flow rate, specifically, the control valve 4 includes: a baffle a41 installed in the middle section of part of the conveying pipe 3, a groove b42 opened at the top of the baffle a41, a baffle b43 slidably connected to the inner wall of the groove b42, and a handle 44 welded to the top of the baffle b43.

[0065] Finally, in order to connect the mounting base 5 and the heat exchange chamber 201, specifically, the mounting base 5 has a rotating groove 51 on its outer periphery, and the heat exchange chamber 201 has an installation groove 52 on its outer wall. The rotating groove 51 and the installation groove 52 are threaded together. The outer end of the heat exchange tube 204 is welded to the inner wall of the installation groove 52. A limit ring b53 is welded to the outer periphery of the mounting base 5 to prevent excessive threading between the rotating groove 51 and the installation groove 52.

[0066] Combination Figures 1-6The specific operation process of the continuous cooling and transfer device for chloroalkanes in this embodiment is as follows:

[0067] 1. Based on actual usage, connect the mounting bases 5 at both ends of the heat exchange chamber 201 to the corresponding conveying pipes 3. Align the connecting groove 109 at the front end of the conveying pipe 3 with the sealing plate 104 on the mounting base 5 and insert it to achieve initial positioning and sealing. Then, push the sliding collar 102 forward so that it slides along the limiting ring a101 on the conveying pipe 3. When the limiting groove b108 on the sliding collar 102 moves to the position of the limiting block 107 on the mounting base 5, under the thrust of the damping spring shock absorber 106, the limiting block 107 will be locked into the limiting groove b108, forming a firm mechanical interlock, thereby completing a quick and sealed connection between the conveying pipe 3 and the mounting base 5.

[0068] 2: After the chloroalkane reaction is complete, open the control valve 4, and adjust the opening of the baffle b43 in the slide b42 by adjusting the handle 44 to adjust the flow rate of the high-temperature chloroalkane flowing out of the reactor 1.

[0069] 3: High-temperature materials flow into heat exchange tube 204 through conveying pipe 3. During this process, the material flow impacts turbine blade 210, driving the rotating shaft 207 and the spiral blade 208 fixed on the rotating shaft 207 to rotate synchronously. The rotating spiral blade 208 effectively hinders the forward fluid and can actively reduce the material flow rate to the ideal range. At the same time, during the rotation, the outer edge of the spiral blade 208 will rotate closely against the inner wall of the heat exchange tube 204, forming a continuous scraping effect, effectively preventing material crystallization or scaling, and realizing the self-cleaning function during operation. The cooling medium flows in from the inlet 202 of the heat exchange chamber 201 and is discharged through the outlet 203, continuously carrying away heat, thereby achieving efficient and uniform cooling of the material.

[0070] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
