Description

Technical Field

[0001] The invention relates to the technical field of reactors, and in particular to a glass-lined reactor. Background Art

[0002] Glass lining is a material that is made by coating a high-silicon dioxide glass glaze on a metal surface and firmly attaching it to the metal surface through high-temperature calcination. This material has the dual advantages of chemical stability similar to glass and metal strength. Glass-lined equipment is mainly used as corrosion-resistant equipment in the fields of chemical, pharmaceutical, pesticide, dye, light industry, food manufacturing and defense industry. For example, a glass-lined reactor is a common application. It lines the inner surface of a steel container with this glass to form a composite material product, which is widely used in various industrial reactions, storage and other processes.

[0003] When the existing glass-lined reactor is mixing and stirring the raw materials, after a certain period of time, the temperature inside the reactor will gradually rise, and the temperature control system of the reactor begins to use the jacket, inner coil and other equipment to adjust the reaction temperature through water circulation, and gradually reach the optimal reaction temperature. The inner coil is usually arranged in a spiral shape inside the reactor along the vertical direction, the inner coil water inlet is located at the top of the reactor, and the inner coil water outlet is located at the bottom of the reactor. When the reactor needs to be cooled, cooling water is usually injected from the inner coil water inlet, and after passing through the inner coil, it is finally discharged from the inner coil water outlet.

[0004] In the above technology, when less raw materials need to be processed, cooling water is injected from the water inlet of the inner coil, and after passing through the inner coil, it is discharged from the water outlet of the inner coil. This will make the cooling water flow path longer, resulting in slower circulation of the cooling water and lower cooling efficiency of the reactor. Summary of the invention

[0005] The present invention provides a glass-lined reactor, aiming to solve the technical problem in the prior art that when a small amount of raw materials needs to be processed, cooling water is injected from the water inlet of the inner coil, and after passing through the inner coil, the cooling water is discharged from the water outlet of the inner coil, which makes the cooling water flow path longer, resulting in slower circulation of the cooling water and low efficiency in cooling the reactor.

[0020] Beneficial effect: By setting up the water return device, the cooling water can be circulated quickly and the used cooling water can be collected efficiently.

[0021] The beneficial effects of the present invention are: In the present invention, through the arrangement of cooling devices, multiple cooling devices are arranged along the height direction of the reactor body. After the material enters the reactor body, the material accumulates in the reactor body and squeezes the load-bearing mechanisms at multiple heights below the material. The load-bearing mechanism drives the cooling component to move. The cooling component is connected to the rotating ring. When the stirring shaft rotates, it can drive the stirring blade to rotate, and drive the load-bearing mechanism, the cooling component and the rotating ring to rotate.

A plurality of cooling blades 442 are provided along the length direction of the connecting pipe 441 . A cooling cavity 443 is provided in the cooling blades 442 . The connecting pipe 441 is connected to the cooling cavities 443 of the plurality of cooling blades 442 .

[0034] Reference Figure 3-Figure 5 A blocking piece 5 for blocking the end of the fixed tube 431 close to the connecting portion 444 is fixedly provided. The blocking piece 5 is provided with a plurality of elastic pieces separately arranged. The elastic pieces are made of elastic rubber material. After the connecting portion 444 of the connecting tube 441 is inserted into the fixed tube 431, the blocking piece 5 can be stretched open. At this time, the fixed tube 431 is opened and the fixed tube 431 is connected with the connecting portion 444. When the connecting portion 444 is located outside the fixed tube 431, the elastic restoring force of the blocking piece 5 can drive the blocking piece 5 to reset, so that the blocking piece 5 blocks the fixed tube 431. At this time, the fixed tube 431 is no longer connected with the connecting portion 444.

[0035] Reference Figure 3-Figure 5After the load-bearing mechanism is squeezed by the material, the cooling assembly 44 is pushed to slide, and the cooling assembly 44 is connected to the water storage chamber 411, and the interior of the reactor body 1 is cooled. A sliding block 6 is fixedly arranged at one end of the connecting pipe 441 away from the fixed pipe 431. The sliding block 6 is a rectangular block, and the sliding block 6 is slidably matched with the stirring blade 21. The end of the sliding block 6 away from the connecting portion 444 is set as a triangular structure. The load-bearing mechanism includes a load-bearing plate 45 for receiving materials, a sliding rod 46 that slides and fits on the stirring blade 21 along the vertical direction, an extrusion block 47 for squeezing the sliding block 6, and a reset assembly 48 for driving the extrusion block 47 and the sliding block 6 to reset. The load-bearing plate 45 is a truncated cone plate, and the top end of the load-bearing plate 45 is a small end, and the bottom end is a large end. One end of the sliding rod 46 is fixedly connected to the bottom end of the load-bearing plate 45, and the other end is fixedly connected to the extrusion block 47.

[0036] Among them, refer to Figure 3-Figure 5 The reset assembly 48 includes an elastic member 481 for driving the extrusion block 47 to reset and an elastic member 482 for driving the sliding block 6 to reset. The elastic member 481 and the elastic member 482 are both springs.

One end of the elastic member 482 is fixedly connected to the stirring blade 21, and the other end is fixedly connected to the sliding block 6. In the initial state, the elastic member 481 drives the extrusion block 47, the sliding rod 46 and the load-bearing plate 45 to rise. At this time, the load-bearing plate 45 is at the highest position in the vertical direction. When the material is added to the reactor body 1, the material at the corresponding height in the reactor body 1 will squeeze the load-bearing plate 45, thereby causing the load-bearing plate 45 at the corresponding height to descend, driving the sliding rod 46 and the extrusion block 47 to descend, and squeezing the sliding block 6.

[0037] Reference Figure 2-Figure 4A water return device 7 is provided on the stirring blade 21, and the water return device 7 is used to collect the cooling water after use. The water return device 7 includes a water return pipe 71 slidably fitted on the stirring blade 21, a water return ring 1 72 provided on the water return pipe 71, a water return ring 2 73 fixedly provided on the reactor body 1, and a drain pipe 74 fixedly provided on the water return ring 2 73. A cavity is provided in the stirring blade 21 located at the water return pipe 71, and the water return pipe 71 is connected with the stirring blade 21, and the water return pipe 71 is connected with the cooling blade 442. The structure of the water return ring 1 72 is the same as that of the rotating ring 43, and the structure of the water return ring 2 73 is the same as that of the water storage ring 41. The return water ring 1 72 is rotatably matched with the return water ring 2 73. A pipeline is arranged between the return water pipe 71 and the return water ring 1 72. A sealing piece 5 (not shown in the figure) is also arranged in the pipeline. The return water pipe 71 is slidably matched with the pipeline. A pipe with the same structure as the connecting part 444 is arranged at one end of the return water pipe 71 close to the pipeline; a valve is arranged on the drain pipe 74, and the cooling water in the cooling blade 442 can enter the return water pipe 71, the cavity of the stirring blade 21 and between the return water ring 1 72 and the return water ring 2 73 to cool the reactor body 1. At this time, the valve is closed; when the cooling water is used, the valve is opened, and the cooling water can be discharged through the drain pipe 74.

[0038] Reference Figure 2 and Figure 3 A temperature sensor 8 is fixedly provided on the stirring blade 21, and the temperature sensor 8 is electrically connected to the controller. The controller is electrically connected to the water supply part of the water supply assembly 42. When the stirring blade 21 is working, the temperature inside the reactor body 1 is high, and the inside of the reactor body 1 needs to be cooled, the temperature sensor 8 transmits an electrical signal to the controller, the controller controls the water supply part to start, and the water supply part transports cooling water to cool the inside of the reactor body 1.

[0039] The implementation principle of a glass-lined reactor of the present invention is as follows: when it is necessary to process materials, the materials are first added into the reactor body 1. At this time, the materials at the corresponding height in the reactor body 1 will squeeze the load-bearing plate 45, thereby causing the load-bearing plate 45 at the corresponding height and the load-bearing plate 45 below to drop. The load-bearing plate 45 drives the sliding rod 46 and the squeezing block 47 to drop, stretches the elastic member 1 481, and squeezes the sliding block 6, so that the sliding block 6 drives the connecting pipe 441 to slide in the direction away from the stirring shaft 2, and stretches the elastic member 2 482. At this time, the connecting pipe 441 drives the connecting part 444, the cooling blade 442 and the return pipe 71 to slide, and the return pipe 71 slides in the stirring blade 21. The connecting part 444 can slide into the fixed pipe 431 and squeeze the blocking piece 5, so that the blocking piece 5 undergoes elastic deformation. At this time, the connecting part 444 is located in the fixed pipe 431, and the connecting part 444 is connected to the fixed pipe 431, and the return pipe 71 is located in the pipeline of the return ring 1 72; Then the stirring shaft 2 rotates, driving the stirring blade 21 to rotate. When the stirring blade 21 rotates, it can drive the connecting pipe 441, the rotating ring 43, the cooling blade 442, the return pipe 71 and the return ring 72 to rotate. During the rotation of the connecting pipe 441, the rotating ring 43, the cooling blade 442, the return pipe 71 and the return ring 72, the stirring effect on the material can be improved, so that the stirring of the material is more uniform; At the same time, when the temperature inside the reactor body 1 is high and the reactor body 1 needs to be cooled, the temperature sensor 8 transmits an electrical signal to the controller, and the controller controls the water supply component to start, and the water supply component transports the cooling water. The cooling water enters the water storage chamber 411 through the water supply pipe 421, and then enters the connection part 444, the connection pipe 441, the cooling blade 442, the return pipe 71 and the cavity of the stirring blade 21 through the fixed pipe 431 in sequence. The connection pipe 441, the cooling blade 442, the return pipe 71 and the stirring blade 21 are in full contact with the material, and the material is efficiently cooled, thereby cooling the inside of the reactor body 1. When the cooling water is in use and the temperature is high, the valve of the drain pipe 74 is opened, and the cooling water can be discharged through the drain pipe 74. Then the water supply component continues to transport the cooling water, thereby realizing the circulation of the cooling water. When cooling is no longer required in the reactor body 1, the water supply parts no longer work, and the drain pipe 74 discharges the cooling water. After the material is processed in the reactor body 1, the material is discharged from the bottom end of the reactor body 1. At this time, the material no longer squeezes the load-bearing plate 45, and the elastic member 481 and the elastic member 482 release the elastic restoring force. The elastic member 481 drives the sliding rod 46, the extrusion block 47 and the load-bearing plate 45 to reset. The elastic member 482 drives the sliding block 6, the connecting pipe 441, the connecting part 444, the cooling blade 442 and the return pipe 71 to slide and reset. The connecting part 444 slides out of the fixed pipe 431, and the return pipe 71 slides out of the pipe of the return ring 72 to reset. At the same time, the sealing piece 5 is elastically deformed and reset to complete the processing of the material.
