Description

Technical Field

[0001] This utility model relates to a constant temperature stirring device for caprolactam processing, belonging to the technical field of stirring devices. Background Technology

[0002] Caprolactam is an important organic chemical raw material. Its main use is to produce polyamide chips through polymerization, which can be further processed into nylon fibers, engineering plastics, and plastic films, with different focus areas of application.

[0003] Chinese Patent Publication No. CN 211871834 U discloses a preheating device for caprolactam polymerization raw materials, relating to the technical field of caprolactam production equipment. Addressing the problem of poor performance in existing preheating devices, the following solution is proposed: A base is included, with vertically arranged support blocks welded to both ends of the top of the base. A horizontally arranged preheating chamber is located between the two support blocks. Horizontally arranged mounting cavities are opened on both sides of the preheating chamber. Heating wires are installed inside the mounting cavities. A horizontally arranged drive motor is screwed to the support block located at the right end of the base. The output end of the drive motor is connected to a horizontally arranged rotating shaft. This invention can quickly and effectively preheat caprolactam polymerization raw materials, uniformly stir the raw materials, and ensure sufficient contact between the caprolactam polymerization raw materials and the components inside the preheating device, thereby effectively improving the preheating progress of the caprolactam polymerization raw materials.

[0004] High-powered mixers are typically equipped with high-speed mixing rotors and mixing blades. These rotors and blades generate strong shear and centrifugal forces when rotating. Under normal circumstances, the strong shear force generated by the high-speed rotating impeller and its jet core with the surrounding fluid is sufficient to mix the materials evenly. However, if the rotor and mixing blades rotate at too high a speed or the material viscosity is too high, it may increase the risk of the equipment tipping over, thereby affecting the normal mixing operation of the equipment and making it inconvenient for operators to use.

[0005] Therefore, a constant-temperature stirring device for caprolactam processing is proposed. Utility Model Content

[0006] In view of this, the present invention provides a constant temperature stirring device for caprolactam processing to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: a constant temperature stirring device for caprolactam processing includes a stirring tank, a tank cover is provided on the top of the stirring tank, a feeding end is installed on the top of the tank cover, a discharging end is installed on the right side of the stirring tank, a stirring motor is installed on the top of the tank cover, a stirring rod is fixedly connected to the output end of the stirring motor, and a fixing plate is installed in the middle of the stirring tank.

[0008] The surface of the fixed plate is provided with a stabilizing mechanism, which includes a servo motor, driven gears, and first connecting rods. The servo motor is installed at the bottom of the fixed plate. The four driven gears are movably connected to the top of the fixed plate around the perimeter. The four first connecting rods are located around the perimeter of the mixing tank. The outer sides of the four first connecting rods are movably connected to U-shaped plates. The inner sides of the four U-shaped plates are movably connected to second connecting rods. The other ends of the four second connecting rods are movably connected to mounting plates. The four mounting plates are installed around the perimeter of the mixing tank.

[0009] More preferably, the output end of the servo motor is fixedly connected to a drive gear, and a gear ring is provided on the top of the fixed plate. The surface of the drive gear meshes with the surface of the gear ring, and the surface of the gear ring meshes with the surfaces of the four driven gears.

[0010] More preferably, each of the four driven gears is fixedly connected to a lead screw at its bottom, and each of the four lead screws is threadedly connected to a screw block on its surface. The outer sides of each of the four screw blocks are movably connected to the inner sides of the four first connecting rods.

[0011] More preferably, each of the four U-shaped plates has a shock-absorbing block installed at its bottom, and all four shock-absorbing blocks are made of rubber.

[0012] More preferably, limit rods are installed around the bottom of the fixing plate, and the four limit rods are slidably connected to the inner surfaces of the four screw blocks.

[0013] More preferably, the top of the fixing plate is provided with a circular groove, and the bottom of each of the toothed rings is provided with a support block, and the bottom of each of the six support blocks is slidably connected to the inner cavity of the circular groove.

[0014] More preferably, the top of the box cover is threaded with mounting bolts on all four sides, and the bottom of each of the six mounting bolts is threaded to the inner surface of the mixing box.

[0015] More preferably, the inner surface of the mixing tank is provided with a cavity, and a heating plate is installed in the inner cavity of the cavity.

[0016] The present invention has the following advantages due to the adoption of the above technical solution:

[0017] I. This utility model, through the setting of a stabilizing mechanism, uses the output of a servo motor to drive the gear ring to rotate via the drive gear. At this time, the gear ring, in cooperation with the driven gear, causes the screw block to move downwards, causing the first connecting rod to flip and the U-shaped plate to flip synchronously. The U-shaped plate then drives the second connecting rod to flip synchronously. At this time, the bottom of the shock absorber block contacts the ground. Through the contact between the shock absorber block and the ground, and the triangular support formed by the lead screw, the first connecting rod, the second connecting rod, and the mounting plate, the mixing tank can be supported synchronously from all sides. This effectively avoids the possibility of the mixing tank shaking and tipping over due to centrifugal force deviation caused by the excessive speed of the stirring rod during equipment operation. This improves the overall stability of the equipment during operation and makes it easier for operators to use.

[0018] II. This utility model incorporates shock-absorbing blocks, whose material properties effectively buffer vibrations generated during mixing. Limiting rods restrict the movement of the screw block, preventing it from shifting and affecting the stability of the mixing chamber. Circular grooves and support blocks limit the movement of the toothed ring, preventing it from shifting during rotation and affecting its support. Mounting bolts allow for the installation and removal of the chamber cover, facilitating maintenance and repair of the connected components. A heating plate allows for temperature control within the mixing chamber, enabling constant-temperature mixing of materials.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-5 As shown, this utility model embodiment provides a constant temperature stirring device for caprolactam processing, including a stirring tank 1, a tank cover 4 on the top of the stirring tank 1, a feeding end 5 installed on the top of the tank cover 4, a discharging end 6 installed on the right side of the stirring tank 1, a stirring motor 7 installed on the top of the tank cover 4, a stirring rod 8 fixedly connected to the output end of the stirring motor 7, and a fixing plate 3 installed in the middle of the stirring tank 1.

[0031] A stabilizing mechanism 2 is provided on the surface of the fixed plate 3. The stabilizing mechanism 2 includes a servo motor 201, driven gears 204, and first connecting rods 207. The servo motor 201 is installed at the bottom of the fixed plate 3. The four driven gears 204 are movably connected to the top of the fixed plate 3 around the perimeter. The four first connecting rods 207 are located around the mixing tank 1. U-shaped plates 208 are movably connected to the outer sides of the four first connecting rods 207. Second connecting rods 209 are movably connected to the inner sides of the four U-shaped plates 208. The other ends of the four second connecting rods 209 are movably connected to mounting plates 21. 0. Four mounting plates 210 are installed around the mixing tank 1. The output end of the servo motor 201 is fixedly connected to the drive gear 202. The top of the fixed plate 3 is provided with a gear ring 203. The surface of the drive gear 202 meshes with the surface of the gear ring 203. The surface of the gear ring 203 meshes with the surfaces of the four driven gears 204. The bottom of each of the four driven gears 204 is fixedly connected with a lead screw 205. The surface of each of the four lead screws 205 is threaded with a screw block 206. The outer sides of each of the four screw blocks 206 are movably connected to the inner sides of the four first connecting rods 207.

[0032] By setting a stabilizing mechanism 2, the output of the servo motor 201 drives the active gear 202 to rotate the gear ring 203. At this time, the gear ring 203 cooperates with the driven gear 204, the screw block 206 moves downward, and the first connecting rod 207 flips, and the U-shaped plate 208 flips synchronously. The U-shaped plate 208 drives the second connecting rod 209 to flip synchronously. At this time, the bottom of the shock absorber 211 contacts the ground. Through the contact between the shock absorber 211 and the ground, and the triangular support formed by the screw 205, the first connecting rod 207, the second connecting rod 209 and the mounting plate 210, the mixing tank 1 can be supported synchronously around its perimeter. This effectively avoids the possibility of the mixing tank 1 tilting and falling due to centrifugal force deviation caused by the excessive speed of the stirring rod 8 stirring the material during equipment operation. This improves the overall stability of the equipment during operation and makes it easier for operators to use.

[0033] Example 2

[0034] like Figure 1-5As shown, in one embodiment, shock-absorbing blocks 211 are installed at the bottom of each of the four U-shaped plates 208. The four shock-absorbing blocks 211 are all made of rubber. Limiting rods 212 are installed around the bottom of the fixed plate 3. The four limiting rods 212 are slidably connected to the inner surface of the four screw blocks 206. A circular groove 213 is opened at the top of the fixed plate 3. Support blocks 214 are installed at the bottom of each of the toothed rings 203. The bottoms of the six support blocks 214 are slidably connected to the inner cavity of the circular groove 213. Mounting bolts 9 are threaded around the top of the box cover 4. The bottoms of the six mounting bolts 9 are threaded to the inner surface of the mixing box 1. A cavity 10 is opened on the inner surface of the mixing box 1. A heating plate 11 is installed in the inner cavity of the cavity 10.

[0035] By setting up shock-absorbing blocks 211, the vibration generated during stirring can be buffered due to the characteristics of their material. By setting up limiting rods 212, the movement of screw blocks 206 can be limited to prevent them from shifting and affecting the stability of the mixing tank 1. By setting up circular grooves 213 and support blocks 214, the movement of toothed rings 203 can be limited to prevent them from shifting during rotation and affecting the support of the mixing tank 1. By setting up mounting bolts 9, the tank cover 4 can be installed or removed, facilitating maintenance and repair of the components connected to the tank cover 4. By setting up heating plates 11, the temperature inside the mixing tank 1 can be easily raised, thus facilitating constant-temperature stirring of the materials inside the mixing tank 1.

[0036] In use: Material is injected into the inner cavity of the mixing tank 1 through the feed end 5. Then, through the output of the servo motor 201, the drive gear 202 rotates. At this time, the drive gear 202 drives the gear ring 203 to rotate synchronously, and causes the driven gear 204 to rotate. At this time, the driven gear 204 drives the lead screw 205 to rotate, thereby driving the screw block 206 to move downward. At this time, the first connecting rod 207 flips and pushes the U-shaped plate 208 to flip. At this time, the U-shaped plate 208 synchronously drives the second connecting rod 209 to flip, so that the bottom of the shock absorber 211 contacts the ground, completing the support and stabilization of the mixing tank 1. Then, through the output of the stirring motor 7, the stirring rod 8 rotates and stirs the material in the inner cavity of the mixing tank 1. Finally, the stirred material is discharged through the discharge end 6, completing the stirring work.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
