Description

Technical Field

[0001] The invention relates to the technical field of chemical pharmacy, in particular to a reaction kettle. Background Art

[0002] Reactors are generally understood as containers for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used in petroleum, chemical industry, rubber, pesticides, dyes, medicines, and food.

[0003] When a reactor is used in the pharmaceutical field, there is no sealing mechanism between the reactor cover and the reactor body. During the reaction process, heat may dissipate to the outside, thereby causing the temperature inside the reactor to drop, seriously affecting the reaction effect. Moreover, most of the current reactors only use a stirring rod to stir and mix, and it is difficult to effectively scrape off the drug residues remaining on the inner wall of the reactor, which can easily cause a waste of resources, a slow reaction rate, and a long time, affecting work efficiency. Therefore, the present application provides a reactor to meet the needs. Summary of the invention

[0008] In a possible implementation, the sealing assembly includes a sealing groove, a mounting seat, a mounting groove, a sealing ring, an air cavity, a piston and a connecting port, the sealing groove is opened on the inner wall of the reactor near the top, the mounting seat is fixedly connected to the bottom of the reactor cover and is adapted to the size of the inner cavity of the reactor, the mounting groove is opened on the outer periphery of the mounting seat, the sealing ring is installed inside the mounting groove, the sealing ring is made of rubber and is hollow inside, the air cavity is opened inside the mounting seat, the piston is slidably connected to the air cavity and is adapted to the size, and the connecting port is opened at the bottom of one end of the air cavity and is communicated with the sealing ring.

[0009] In a possible implementation, the sealing assembly also includes an adjusting groove, an adjusting rod, a connecting rod, a fixing hole, a mounting block, a through groove and a fixing rod. The adjusting groove is opened at the top of the kettle cover and is connected to the air cavity. The adjusting rod is slidably connected to the adjusting groove. Both ends of the connecting rod are respectively fixedly connected to the piston and the adjusting rod. Four groups of fixing holes are provided and are respectively opened on both sides of both ends of the adjusting groove. The through groove runs through the mounting block. The mounting block is slidably connected to the outer periphery of the adjusting rod through the through groove. The fixing rod is fixedly connected to both sides of the bottom of the mounting block and is adapted to the size of the fixing hole.

[0010] In a possible implementation, the sealing assembly also includes a slide groove, a slider and a spring. The slide groove is opened on one side surface of the adjusting rod, the slider is fixedly connected to the inner wall of the through groove and slidably connected to the slide groove, and the spring is installed inside the slide groove and its two ends are respectively fixedly connected to the top of the slider and the inner wall of the top of the slide groove.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: By providing a sealing component, the mounting block is pulled upward to drive the slider to slide upward along the slide groove and squeeze the spring. When the fixing rod moves upward with the mounting block to move out of the fixing hole, the adjusting rod is slid along the adjusting groove to drive the piston to slide synchronously along the air cavity through the connecting rod. During this process, the air in the air cavity is sent to the sealing ring through the connecting port. When the adjusting rod slides from one end of the adjusting groove to the other end, all the air in the air cavity is sent to the sealing ring. At this time, the sealing ring expands to be stuck in the sealing groove, and then the mounting block is released. The spring rebounds and drives the mounting block to move downward through the slider. When the fixing rod moves downward with the mounting block to be inserted into the fixing hole at the current position, the sealing ring can maintain the current state. This design can seal the connection between the reactor and the reactor cover through the sealing ring, effectively preventing heat leakage from affecting the reaction effect. By providing a stirring assembly, the first motor is started to drive the stirring rod to rotate through the driving shaft, and the rotation of the stirring rod drives the limit block to rotate. Since the limit block is fixedly connected to the guide rod, the guide rod will drive the sliding block to rotate during the rotation process, thereby causing the sliding block to rotate. At this time, the support rod and the stirring plate on the surface of the connecting rod rotate to stir the pharmaceutical raw materials in the reactor. At this time, the hydraulic rod is started to push the sliding block, so the sliding block moves up and down on the surface of the stirring rod. At this time, the connecting rod drives the scraper to scrape off the pharmaceutical raw material residue on the inner wall of the reactor to prevent the residue from adhering to the inner wall of the reactor, thereby reducing the waste of resources.

[0014] Start the second motor to drive the gear to rotate. Since the gear is meshed with the latch, the mounting ring will drive the reactor to rotate synchronously with the gear. During this process, the rotating block rotates synchronously along the rotating groove and limits the reactor. This design can make the stirring of the raw materials more thorough by rotating the stirring rod and the reactor body in different directions, thereby effectively improving the reaction rate of the raw materials.

At this time, the connecting rod 42 drives the scraper 47 to scrape off the pharmaceutical raw material residue on the inner wall of the reactor 1 to prevent the residue from adhering to the inner wall of the reactor 1 and to avoid waste of resources.

[0027] In some examples, the sealing assembly 6 includes a sealing groove 61, a mounting seat 62, a mounting groove 63, a sealing ring 64, an air cavity 65, a piston 66 and a connecting port 67. The sealing groove 61 is opened on the inner wall of the reactor 1 near the top, the mounting seat 62 is fixedly connected to the bottom of the reactor cover 2 and is adapted to the size of the inner cavity of the reactor 1.

When the sealing ring 64 expands to fit into the sealing groove 61, the connection between the reactor 1 and the reactor cover 2 can be sealed, effectively preventing the heat leakage in the reactor 1 from affecting the reaction rate. The sealing assembly 6 also includes an adjusting groove 68, an adjusting rod 69, a connecting rod 610, a fixing hole 611, a mounting block 612, a through groove 613 and a fixing rod 614. The adjusting groove 68 is opened at the top of the reactor cover 2 and is connected with the air cavity 65. The adjusting groove 68 is opened at the top of the reactor cover 2 and is connected with the air cavity 65. The rod 69 is slidably connected to the adjusting groove 68, and the two ends of the connecting rod 610 are fixedly connected to the piston 66 and the adjusting rod 69 respectively.

The fixing rod 614 is fixedly connected to both sides of the bottom of the mounting block 612 and is adapted to the size of the fixing hole 611. The position of the adjusting rod 69 can be adjusted by removing the fixing rod 614 from the fixing hole 611, and the adjusting rod 69 can be fixed by inserting the fixing rod 614 into the fixing hole 611.

[0029] In a specific application scenario, the raw materials to be processed are first placed in the reactor 1, or are fed into the reactor 1 from the feed port 5, and then the reactor cover 2 is installed on the top of the reactor 1.

When the fixing rod 614 moves upward with the mounting block 612 and moves out of the fixing hole 611, the adjusting rod 69 is slid along the adjusting groove 68 to drive the piston 66 to slide synchronously along the air cavity 65 through the connecting rod 610. In this process, the air in the air cavity 65 is released through the connecting rod 610. The interface 67 is sent to the sealing ring 64. When the adjusting rod 69 slides from one end of the adjusting groove 68 to the other end, all the air in the air cavity 65 is sent to the sealing ring 64. At this time, the sealing ring 64 expands to be stuck in the sealing groove 61, and then the mounting block 612 is released. The spring 617 rebounds and drives the mounting block 612 to move downward through the slider 616. When the fixing rod 614 moves downward with the mounting block 612 to be inserted into the fixing hole 611 at the current position, the sealing ring 64 can maintain the current state, thereby sealing the connection between the reactor cover 2 and the reactor 1 to prevent heat leakage from affecting the reaction rate. Then the first motor 3 is started to The driving shaft drives the stirring rod 41 to rotate, and the rotation of the stirring rod 41 drives the limit block 49 to rotate. Since the limit block 49 is fixedly connected to the guide rod 48, the guide rod 48 will drive the sliding block 43 to rotate during the rotation, so that the sliding block 43 rotates. At this time, the support rod 44 and the stirring plate 46 on the surface of the connecting rod 42 rotate to stir the pharmaceutical raw materials in the reactor 1. At this time, the hydraulic rod 410 is started to push the sliding block 43, so the sliding block 43 will move up and down on the surface of the stirring rod 41. At this time, the connecting rod 42 drives the scraper 47 to scrape the pharmaceutical raw material residue on the inner wall of the reactor 1. In order to prevent residues from adhering to the inner wall of the reactor 1 and to avoid waste of resources, the second motor 86 is started to drive the gear 87 to rotate. Since the gear 87 is meshed with the latch tooth 84, the mounting ring 82 will drive the reactor 1 to rotate synchronously with the gear 87. During this process, the rotating block 83 rotates synchronously along the rotating groove 81 and limits the reactor 1. By rotating the first motor 3 and the second motor 86 in different directions, the stirring of the raw materials can be more thorough, thereby increasing the reaction rate of the raw materials. After the reaction is completed, the operation of the first step is repeated to pump the air in the sealing ring 64 into the air cavity 65 to remove the reactor cover 2.
