Abstract
Description
Technical Field
[0001] This utility model belongs to the field of nylon polymerization processing technology, specifically relating to a cooling structure for a nylon polymerization device. Background Technology
[0002] Nylon is a high-performance synthetic fiber with advantages such as high strength, high abrasion resistance, good elasticity and resilience, and is widely used in textiles, apparel, industrial products, and outdoor products. Nylon polymerization is a key step in nylon production. Its core is the polymerization of monomers into high molecular weight compounds through a chemical reaction. This process is mainly used to remove oligomers and unreacted monomers from the chips, thereby improving the purity and quality of the product. During the operation of the polymerization unit, a cooling system is typically used to ensure the normal operation and service life of the reactor.
[0003] Currently, the cooling devices for existing polymerization plants are either directly installed inside the outer wall of the polymerization plant or fixedly mounted on the outside of the polymerization plant. After installation in either of these ways, when the cooling device malfunctions and needs to be disassembled, the subsequent disassembly process is particularly complicated and cannot be carried out quickly, thus greatly reducing the efficiency of subsequent maintenance.
[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a cooling structure for a nylon polymerization apparatus. Utility Model Content
[0005] The purpose of this invention is to provide a cooling structure for a nylon polymerization device that can solve the problem of inconvenient disassembly and cumbersome assembly and disassembly of the cooling device in existing polymerization devices.
[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:
[0007] A cooling structure for a nylon polymerization apparatus includes: a first cooling shroud and a second cooling shroud, a water circulation mechanism, and a locking mechanism.
[0008] The first cooling cover and the second cooling cover are rotatably connected. The water circulation mechanism is installed on one side of the first cooling cover and the second cooling cover and is connected to the first cooling cover and the second cooling cover. The locking mechanism is installed on the first cooling cover and the second cooling cover. The locking mechanism includes a U-shaped lock head and a fixing seat respectively fixed on the first cooling cover and the second cooling cover. A first locking rod is slidably arranged on the fixing seat. A fixing head is fixed at the end of the first locking rod away from the U-shaped lock head. A locking nut is threaded to the end of the first locking rod that passes through the U-shaped lock head. The locking mechanism also includes a second locking component.
[0009] In one embodiment of this utility model, multiple layers of partitions are provided inside both the first and second cooling covers, which divide the contents of the first and second cooling covers into S-shaped flow channels. Both the first and second cooling covers are provided with inlets and outlets, which are used to connect to a water circulation mechanism. The cooling medium flows into the first or second cooling cover from the inlet and then flows out from the outlet.
[0010] In one embodiment of this utility model, an insulation shell is installed on the outer side of both the first cooling cover and the second cooling cover. The insulation shell plays a role in heat preservation for the first cooling cover and the second cooling cover, preventing the cold energy inside the first cooling cover and the second cooling cover from being consumed from the outside, so that the cooling medium inside the first cooling cover and the second cooling cover mainly absorbs the heat energy inside the polymerization device.
[0011] In one embodiment of the present invention, a hinge for rotatable connection is provided between the first cooling cover and the second cooling cover, and the first cooling cover and the second cooling cover are rotatably connected by the hinge.
[0012] In one embodiment of this utility model, the water circulation mechanism includes: multiple water pipes, a water pump, and a heat exchanger. The multiple water pipes are used to transport the cooling medium. The water pump is located on one side of the first cooling shroud and the second cooling shroud, and is connected to a pair of inlet and outlet water pipes via two pairs of water pipes. The water pump drives the flow of the cooling medium within the first and second cooling shrouds through the two pairs of water pipes. The heat exchanger is located on one side of the water pump and is connected to the water pump via a pair of water pipes. The heat exchanger is used to dissipate heat from the cooling medium.
[0013] In one embodiment of this utility model, the second locking assembly includes: a pair of second locking rods, a pair of fixed shafts, a pair of control members, and a pair of locking members. The pair of second locking rods are fixed to the first cooling cover and are respectively located on the upper and lower sides of the U-shaped lock head. The pair of fixed shafts are fixed to the second cooling cover and are respectively located on the upper and lower sides of the fixing base. The pair of control members are respectively fixed to the upper and lower ends of the fixing head. The pair of locking members rotate on the pair of fixed shafts, with one end hooked onto the second locking rod and the other end sliding on the control member.
[0014] In use, the first locking rod pulls the fixing head, causing the fixing head to move the control component towards the locking component. The control component pushes one end of the locking component, causing the locking component to rotate around the fixed shaft, thereby hooking the other end of the locking component onto the second locking rod, thus achieving a secondary locking between the first and second cooling covers.
[0015] In one embodiment of this utility model, the control component includes: a bearing seat, a locking hook, and an L-shaped fixing rod. The bearing seat rotates on a fixed shaft. The locking hook is fixed to the bearing seat and hooks onto a second locking rod. The L-shaped fixing rod is fixed to the bearing seat, and its end away from the bearing seat slides on the control component. When the control component pushes the L-shaped fixing rod, it causes the bearing seat to rotate, and the rotation of the bearing seat causes the locking hook to hook onto the second locking rod.
[0016] In one embodiment of this utility model, the control component includes: a pair of control levers and a slide groove. The pair of control levers are both fixed to a fixed head. The slide groove is formed in the pair of control levers.
[0017] In one embodiment of this utility model, a slider is fixed at the end of the L-shaped fixing rod away from the shaft seat. The slider slides in the groove, so that when the fixing head drives the control rod to move, it drives the locking member to rotate.
[0018] In one embodiment of this utility model, a spring is installed on the first locking rod between the fixing head and the fixing seat, and the spring force is used to push the fixing head to move in the opposite direction to the fixing seat.
[0019] Compared with the prior art, this utility model, through coherent structural design, can quickly complete the installation and disassembly of the cooling device, thereby effectively improving the installation and disassembly efficiency of the cooling device. Attached Figure Description

Detailed Implementation
[0027] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.
[0028] like Figures 1 to 4 As shown, a cooling structure for a nylon polymerization device according to an embodiment of the present invention includes: a first cooling cover 1 and a second cooling cover 101, a water circulation mechanism, and a locking mechanism 2. The first cooling cover 1 and the second cooling cover 101 are rotatably connected. The water circulation mechanism is installed on one side of the first cooling cover 1 and the second cooling cover 101 and connected to the first cooling cover 1 and the second cooling cover 101. The locking mechanism 2 is installed on the first cooling cover 1 and the second cooling cover 101. The locking mechanism 2 includes a U-shaped lock head 202 and a fixing seat 201 respectively fixed on the first cooling cover 1 and the second cooling cover 101. A first locking rod 203 is slidably arranged on the fixing seat 201. A fixing head 204 is fixed to one end of the first locking rod 203 away from the U-shaped lock head 202. A locking nut 205 is threadedly connected to one end of the first locking rod 203 passing through the U-shaped lock head 202. The locking mechanism 2 also includes a second locking assembly.
[0029] During installation, the first cooling cover 1 and the second cooling cover 101 are first opened by rotating them together. Then, the first and second cooling covers 101 are positioned outside the polymerization device and closed together, so that the inner walls of the first and second cooling covers 101 are in contact with the outer wall of the nylon polymerization device. The first locking rod 203 of the first and second cooling covers 101 is simultaneously engaged in the U-shaped groove of the U-shaped lock head 202. The locking nut 205 is then screwed onto the outside of the U-shaped lock head 202 to secure the first and second cooling covers 101. A second locking assembly is then used to further lock the first and second cooling covers 101 together. In use, the cooling medium inside the first and second cooling covers 101 circulates through a water circulation mechanism, absorbing heat from the nylon polymerization device and thus cooling it.
[0030] like Figure 2 As shown, both the first cooling cover 1 and the second cooling cover 101 are provided with multiple layers of partitions 103, which divide the first cooling cover 1 and the second cooling cover 101 into S-shaped flow channels. Both the first cooling cover 1 and the second cooling cover 101 are provided with inlets 104 and outlets 105, which are used to connect to a water circulation mechanism. The cooling medium flows into the first cooling cover 1 or the second cooling cover 101 from the inlet 104 and then flows out from the outlet 105.
[0031] like Figures 1 to 2 As shown, both the first cooling shroud 1 and the second cooling shroud 101 are equipped with heat-insulating shells 102 on their outer sides. The heat-insulating shells 102 insulate the first cooling shroud 1 and 101, preventing the cold energy inside the first cooling shroud 1 and the second cooling shroud 101 from being consumed from the outside, thus allowing the cooling medium inside the first cooling shroud 1 and the second cooling shroud 101 to mainly absorb the heat energy inside the polymerization device. A hinge 106 is provided between the first cooling shroud 1 and the second cooling shroud 101 for mutual rotational connection, and the first cooling shroud 1 and the second cooling shroud 101 are rotatably connected by the hinge 106.
[0032] like Figure 1 As shown, the water circulation mechanism includes: multiple water pipes 109, a water pump 107, and a heat exchanger 108. The multiple water pipes 109 are used to transport the cooling medium. The water pump 107 is located on one side of the first cooling shroud 1 and the second cooling shroud 101, and is connected to a pair of inlets 104 and outlets 105 via two pairs of water pipes 109. The water pump 107 drives the flow of the cooling medium within the first cooling shroud 1 and the second cooling shroud 101 through the two pairs of water pipes 109. The heat exchanger 108 is located on one side of the water pump 107 and is connected to the water pump 107 via a pair of water pipes 109. The heat exchanger 108 is used to dissipate the heat in the cooling medium.
[0033] like Figures 2 to 4 As shown, the second locking assembly includes: a pair of second locking rods 207, a pair of fixed shafts 208, a pair of control components 210, and a pair of locking components 209. The pair of second locking rods 207 are fixed to the first cooling cover 101 and are respectively located on the upper and lower sides of the U-shaped lock head 202. The pair of fixed shafts 208 are fixed to the second cooling cover 101 and are respectively located on the upper and lower sides of the fixing base 201. The pair of control components 210 are respectively fixed to the upper and lower ends of the fixing head 204. The pair of locking components 209 rotate on the pair of fixed shafts 208, with one end hooked onto the second locking rod 207 and the other end sliding on the control component 210.
[0034] In use, the first locking rod 203 pulls the fixing head 204, causing the fixing head 204 to move the control member 210 towards the locking member 209. The control member 210 pushes one end of the locking member 209, causing the locking member 209 to rotate around the fixing shaft 208, thereby hooking the other end of the locking member 209 onto the second locking rod 207, thus achieving a secondary locking between the first cooling cover 1 and the second cooling cover 101.
[0035] like Figures 3 to 4 As shown, the control component 210 includes: a bearing seat 216, a locking hook 211, and an L-shaped fixing rod 212. The bearing seat 216 rotates on a fixed shaft 208. The locking hook 211 is fixed to the bearing seat 216 and hooks onto a second locking rod 207. The L-shaped fixing rod 212 is fixed to the bearing seat 216, and its end away from the bearing seat 216 slides on the control component 210. When the control component 210 pushes the L-shaped fixing rod 212, it causes the bearing seat 216 to rotate, and the rotation of the bearing seat 216 causes the locking hook 211 to hook onto the second locking rod 207. The control component 210 includes: a pair of control rods 214 and a sliding groove 215. Both of the pair of control rods 214 are fixed to the fixed head 204. The sliding groove 215 is carved into the pair of control rods 214.
[0036] like Figures 3 to 4 As shown, a slider 213 is fixed to the end of the L-shaped fixing rod 212 away from the shaft seat 216. The slider 213 slides in the slide groove 215. By sliding the slider 213 in the slide groove 215, the fixing head 204 drives the control rod 214 to move, thereby driving the locking member 209 to rotate. A spring 206 is installed on the first locking rod 203 between the fixing head 204 and the fixing seat 201. The elastic force of the spring 206 is used to push the fixing head 204 to move in the opposite direction to the fixing seat 201.
[0037] During installation, the first cooling cover 1 and the second cooling cover 101 are first opened by rotating them together. Then, the first cooling cover 1 and the second cooling cover 101 are placed outside the nylon polymerization device, and then the first cooling cover 1 and the second cooling cover 101 are closed together, so that the inner sidewalls of the first cooling cover 1 and the second cooling cover 101 are in contact with the outer sidewall of the nylon polymerization device. When the first cooling cover 1 and the second cooling cover 101 are closed, the first locking rod 203 is also engaged in the U-shaped groove of the U-shaped lock head 202. Then, the locking nut 205 is screwed onto the outside of the U-shaped lock head 202 to fix the first cooling cover 1 and the second cooling cover 101.
[0038] Additionally, when the first locking rod 203 pulls the fixing head 204, the fixing head 204 drives the control rod 214 to move towards the locking member 209. When the control rod 214 pushes the L-shaped fixing rod 212, it causes the bearing seat 216 to rotate. When the bearing seat 216 rotates, it causes the locking hook 211 to hook onto the second locking rod 207, thereby locking the first cooling cover 1 and the second cooling cover 101 a second time.
[0039] Subsequently, the cooling medium inside the first cooling shroud 1 and the second cooling shroud 101 is circulated by the water circulation mechanism, so that the cooling medium absorbs the heat inside the nylon polymerization device, thereby cooling the nylon polymerization device.
[0040] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
