Description

Technical Field

[0001] This utility model relates to the technical field of stirring and mixing devices, specifically to a stirring and mixing device used under high temperature and high pressure. Background Technology

[0002] In many industrial fields, such as chemical engineering, materials science, and pharmaceuticals, mixing operations are often required under extreme conditions of high temperature and high pressure. For example, in some chemical reactions, specific reactants need to be thoroughly mixed under high temperature and high pressure to improve the reaction rate and selectivity, thereby obtaining the desired product. Common mixing devices for high temperature and high pressure environments consist of a mixing tank, mixing components, a feed hopper, a heating component, and a compressor. The following drawbacks have been observed during their use:

[0003] 1. After the high temperature and high pressure mixing process is completed, some material often remains inside the mixing tank. Since the mixing tank is usually a sealed structure with small openings, it is difficult to clean, especially for some highly viscous materials. It is also inconvenient to disassemble, resulting in the mixing tank not being cleaned properly.

[0004] 2. In some processes, raw materials need to be added during mixing according to the reaction progress. However, since the mixing tank is under high temperature and pressure, the feed inlet needs to be opened when adding raw materials, which creates a pressure difference between the inside of the mixing tank and the external environment. According to fluid mechanics principles, when a pressure difference exists, gas or liquid will flow from the area of ​​greater pressure difference to the area of ​​lesser pressure difference, resulting in significant pressure leakage inside the mixing tank. Pressure leakage not only affects the stability of the reaction process but may also cause the reaction to deviate from the predetermined parameters, thus affecting product quality. To maintain the pressure inside the mixing tank, it is often necessary to continuously replenish the gas, which not only increases energy consumption and production costs but may also introduce impurities, further affecting product quality.

[0005] Therefore, in view of this, we studied and improved the existing structure and proposed a stirring and mixing device for high temperature and high pressure. Utility Model Content

[0029] Please see Figure 1-3 A mixing device for high temperature and high pressure conditions includes a mixing tank 1, a mixing assembly 2 inside the mixing tank 1, a feed hopper 101 fixedly connected to the top of the mixing tank 1, a heating assembly 3 inside the mixing tank 1, and a compressor 4 fixedly connected to the top of the mixing tank 1. The mixing tank 1 is composed of an inner tank 102 and an outer tank 103, which are fixedly welded together, forming a heat preservation cavity 104 between the inner tank 102 and the outer tank 103 to maintain the temperature inside the mixing tank 1. The heating assembly 3 is disposed in the heat preservation cavity 104 and includes several heating rods 301 fixedly disposed in the heat preservation cavity 104, and several... Heating rods 301 are connected by several heating rings 302. The two ends of each heating rod 301 are fixedly connected to the inner top and bottom of the outer barrel 103, respectively. The arrangement of the heating rods 301 and heating rings 302 ensures uniform heating within the mixing tank 1. A compressor 4 is fixedly installed at the top of the inner barrel 102, controlling the pressure within the inner barrel 102. The mixing assembly 2 is located inside the inner barrel 102. The mixing assembly 2 includes a mixing shaft 201 rotatably mounted at the top of the inner barrel 102. Several mixing blades 202 are evenly distributed around the mixing shaft 201. A motor 203, which drives the mixing shaft 201 to rotate, is fixedly installed at the top of the inner barrel 102. The rotation of the mixing shaft 201 drives the mixing blades 202 to rotate, thereby mixing the raw materials within the inner barrel 102.

[0030] Please see Figure 1-3 The bottom of the inner barrel 102 is hollow, and a bottom cover 105 is threadedly connected to the bottom of the inner barrel 102. A sealing strip is provided on the bottom cover 105 to increase the sealing performance. A discharge port is provided at the bottom cover 105, and a switch valve is provided at the discharge port. Several latches 106 are evenly distributed around the outer barrel 103.

The threaded connection between the bottom cover 105 and the inner barrel 102 facilitates the disassembly and assembly of the bottom cover 105, allowing the interior of the inner barrel 102 to be opened for cleaning.

[0031] Please see Figure 1-3 The outer barrel 103 has support components 5 on both sides, and the support components 5 control the rotation of the mixing barrel 1 on the support components 5. The support components 5 include a base 501 disposed below the mixing barrel 1. Two support plates 502 are fixedly disposed on the top of the base 501. A connecting block 503 is rotatably disposed on the support plate 502, and the outer barrel 103 is fixedly connected between the two connecting blocks 503. A second motor 504 is fixedly disposed on one side of one of the support plates 502 to drive the rotation of one of the connecting blocks 503.

[0032] Please see Figure 3-4 The feed hopper 101 has two opposing baffles 107 hinged inside. A rotating assembly 6 is provided on one side of the feed hopper 101 to control the rotation of the two baffles 107 simultaneously. The rotating assembly 6 includes two synchronous shafts 601 rotatably mounted on one side of the feed hopper 101, and the synchronous shafts 601 drive the corresponding baffles 107 to rotate.

A synchronous shaft 603 is fixedly mounted on one side of the gears 602, and the corresponding synchronous shafts 601 and 603 are connected by a synchronous belt 604. A receiving plate 605 is fixedly mounted on one side of the feed hopper 101, and a motor 606 is fixedly mounted on one side of the receiving plate 605 to drive the rotation of one of the synchronous shafts 603. Two gears 602 are meshed and connected. When one gear 602 rotates, it can drive the other gear 602 to rotate in the opposite direction. Since the timing belt 604 connects the timing shaft 1 601 and the timing shaft 2 603, when the timing shaft 2 603 rotates, it can drive the timing shaft 1 601 to rotate as well, so that both baffles 107 rotate, thereby opening the entrance from the feed bin 101 to the inner barrel 102.

[0033] Please see Figure 3-4The feed hopper 101 is hinged to a cover plate 108 at its top, and a sealing strip is provided on the cover plate 108 to increase sealing.

When the limit lock 702 rotates, it can move on the threaded cylinder 701 to limit the cover plate 108.

[0034] The working principle of this utility model:

[0035] When mixing raw materials is required, the raw materials are first added from the feed hopper 101 into the inner barrel 102, and then the feed hopper 101 is closed. Next, the motor 203 is started, which drives the stirring shaft 201 to rotate, causing several stirring blades 202 to rotate, thereby stirring the raw materials. Simultaneously, the heating rod 301 and heating ring 302 are activated to heat the insulation chamber 104, thus raising the temperature of the inner barrel 102. The compressor 4 is also activated to regulate the pressure in the inner barrel 102, ensuring the raw materials are mixed under high temperature and high pressure. After mixing is complete, the valve can be controlled to open the discharge port, allowing the raw materials to be discharged.

[0036] If other materials need to be added to the mixed raw materials, first rotate the limit lock 702 to move it on the threaded cylinder 701 so that the limit lock 702 does not abut against the cover plate 108. Then, rotate the cover plate 108 to open the top of the feed hopper 101. Then, the raw materials can be added into the feed hopper 101. Next, rotate the cover plate 108 to cover the feed hopper 101. Then rotate the limit lock 702 to move it on the threaded cylinder 701 so that the limit lock 702 abuts against the cover plate 108. Then, start the motor 606 to rotate one of the gears 602 and one of the synchronous shafts 603. This causes the other gear 602 and the other synchronous shaft 603 to rotate in the opposite direction. Then, the synchronous belt 604 drives the two synchronous shafts 601 to rotate, causing the two baffles 107 to rotate, thereby adding the raw materials into the inner barrel 102.

[0037] If it is necessary to clean the inside of the inner tub 102, first start the motor 504, which will drive one of the connecting blocks 503 to rotate, so that the other connecting block 503 and the mixing tub 1 will rotate. After rotating to the appropriate angle, the motor 504 can be turned off. Then the handle on the latch 106 can be rotated so that the latch 106 is not engaged with the bottom cover 105. Then the bottom cover 105 can be rotated to expose the bottom of the inner tub 102 for cleaning.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
