Description

Technical Field

[0001] The present invention relates to the technical field of reaction kettles, and particularly to a glass-lined reaction kettle. Background Art

[0002] Glass lining is a material obtained by coating a glassy glaze containing high silica on the metal surface and firmly adhering it to the metal surface through high-temperature firing. 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 fields such as chemical industry, medicine, pesticides, dyes, light industry, food manufacturing, and national defense industry. For example, a glass-lined reaction kettle is a common application. It lines the inner surface of a steel container with this glass to form a composite product, which is widely used in various industrial reactions, storage, and other processes.

[0003] In the existing glass-lined reaction kettle during the mixing and stirring of raw materials, after the raw materials are stirred for a certain time, the temperature inside the reaction kettle will gradually rise. The temperature control system of the reaction kettle starts to adjust the reaction temperature through the water circulation method using equipment such as jackets and internal coil pipes, gradually reaching the optimal reaction temperature. The internal coil pipe is usually arranged in a spiral shape along the vertical direction inside the reaction kettle. The water inlet of the internal coil pipe is located at the top of the reaction kettle, and the water outlet of the internal coil pipe is located at the bottom of the reaction kettle. When it is necessary to cool down the reaction kettle, usually, cooling water is injected from the water inlet of the internal coil pipe, and after passing through the internal coil pipe, it finally exits from the water outlet of the internal coil pipe.

[0004] In the above technology, when processing a relatively small amount of raw materials, using the method of injecting cooling water from the water inlet of the internal coil pipe, passing through the internal coil pipe, and then discharging it from the water outlet of the internal coil pipe will result in a longer flow path of the cooling water, slower circulation of the cooling water, and lower cooling and temperature reduction efficiency of the reaction kettle. Summary of the Invention

[0005] The present invention provides a glass-lined reaction kettle, aiming to solve the technical problem in the existing technology that when processing a relatively small amount of raw materials, using the method of injecting cooling water from the water inlet of the internal coil pipe, passing through the internal coil pipe, and then discharging it from the water outlet of the internal coil pipe will result in a longer flow path of the cooling water, slower circulation of the cooling water, and lower cooling and temperature reduction efficiency of the reaction kettle.

[0009] Preferably, the cooling blades are configured as a corrugated structure.

[0010] Beneficial effect: By setting the corrugated structure, the contact area between the cooling blades and the material is increased, thereby improving the cooling efficiency of the cooling blades on the material.

[0015] Beneficial effect: through the setting of the sliding block, the material squeezes the load-bearing plate, which in turn drives the extrusion block to squeeze the sliding block, which can push the connecting pipe to slide. Through the setting of the reset component, the sliding block can be reset when it is not squeezed.

[0016] Preferably, the reset assembly includes an elastic member 1 for driving the extrusion block to reset and an elastic member 2 for driving the sliding block to reset, one end of the elastic member 1 is connected to the stirring blade, and the other end is connected to the extrusion block, one end of the elastic member 2 is connected to the stirring blade, and the other end is connected to the sliding block.

[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:

[0022] In the present invention, through the arrangement of the cooling device, a plurality of cooling devices are arranged along the height direction of the reaction kettle body. After the material enters the reaction kettle body, the material accumulates in the reaction kettle body and presses on the load-bearing mechanisms at multiple heights below the material. The load-bearing mechanism pushes the cooling component to move. The cooling component is communicated with the rotating ring. When the stirring shaft rotates, it can drive the stirring blade to rotate, drive the load-bearing mechanism, the cooling component and the rotating ring to rotate. When it is necessary to cool down the inside of the reaction kettle body, the water supply component is started to supply water into the water storage ring. The cooling water enters the water storage cavity and is conveyed to the cooling component through the rotating ring. The inside of the reaction kettle body is cooled down by the cooling component. The circulation path of the cooling water is short, resulting in a fast circulation of the cooling water, which can improve the efficiency of cooling down the reaction kettle; at the same time, the load-bearing mechanism located above the material does not move, and the cooling component does not move. At this time, when the stirring blade rotates, it will not drive the rotating ring to rotate, which can improve the service life of the rotating ring and the water storage ring.

One end of the water supply pipe 421 is located inside the water storage ring 41. The water supply part directly adopts a water pump, which draws cooling water and transports it to the water storage chamber 411 through the water supply pipe 421 for use.

[0034] Reference Figures 3-5A fixed pipe 431 communicating with the water storage chamber 411 is fixedly provided on the rotating part 433 of the rotating ring 43. The cooling assembly 44 includes a connecting pipe 441 corresponding to the fixed pipe 431 and a cooling blade 442 fixedly provided on the connecting pipe 441 and used to cool the inside of the reactor body 1.

When the connecting portion 444 is located in the fixed pipe 431, the connecting pipe 441 is communicated with the fixed pipe 431 through the connecting portion 444.

[0035] Among them, refer to Figures 3-5 The cooling blades 442 are configured as a corrugated structure. 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 .

[0036] Reference Figures 3-5 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.

[0037] Reference Figures 3-5, after the load-bearing mechanism is squeezed by the material, it pushes the cooling component 44 to slide. The cooling component 44 is communicated with the water storage cavity 411 and cools down the inside of the reactor body 1. 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 is slidably fitted to the stirring blade 21. One end of the sliding block 6 away from the connecting portion 444 is arranged in a triangular structure. The load-bearing mechanism includes a load-bearing plate 45 for receiving the material, a sliding rod 46 slidably fitted to the stirring blade 21 in the vertical direction, a pressing block 47 for pressing the sliding block 6, and a reset assembly 48 for driving the pressing block 47 and the sliding block 6 to reset. The load-bearing plate 45 is a frustum-shaped plate, and the top end of the load-bearing plate 45 is the small end and the bottom end is the 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 pressing block 47. The pressing block 47 is a triangular block and is adapted to one end of the sliding block 6 close to the pressing block 47.

[0038] Among them, referring to Figures 3-5 , the reset assembly 48 includes an elastic member 481 for driving the pressing block 47 to reset and an elastic member 482 for driving the sliding block 6 to reset. Both the elastic member 481 and the elastic member 482 are springs. One end of the elastic member 481 is fixedly connected to the stirring blade 21, and the other end is fixedly connected to the upper surface of the pressing block 47. 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 pressing 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 into 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 pressing block 47 to descend, and pressing the sliding block 6.

[0039] Referring to Figures 2-4, a water return device 7 is provided on the stirring blade 21. The water return device 7 is used to collect the used cooling water. The water return device 7 includes a water return pipe 71 slidably fitted on the stirring blade 21, a first water return ring 72 provided on the water return pipe 71, a second water return ring 73 fixedly provided on the reaction kettle body 1, and a drain pipe 74 fixedly provided on the second water return ring 73. A cavity is formed in the stirring blade 21 where the water return pipe 71 is located. The water return pipe 71 is communicated with the stirring blade 21 and is also communicated with the cooling blade 442. The structure of the first water return ring 72 is the same as that of the rotating ring 43, and the structure of the second water return ring 73 is the same as that of the water storage ring 41. The first water return ring 72 is rotatably fitted in the second water return ring 73. A pipe is provided between the water return pipe 71 and the first water return ring 72, and a blocking piece 5 (not shown in the figure) is also provided in the pipe. The water return pipe 71 is slidably fitted with the pipe. One end of the water return pipe 71 close to the pipe is provided with a pipe having the same structure as the connecting portion 444; a valve is provided on the drain pipe 74. The cooling water in the cooling blade 442 can enter the water return pipe 71, the cavity of the stirring blade 21, and the space between the first water return ring 72 and the second water return ring 73 to cool down the reaction kettle body 1. At this time, the valve is closed; when the cooling water is used up, the valve is opened, and at this time, the cooling water can be discharged through the drain pipe 74.

[0040] Referring to Figure 2 and Figure 3 , a temperature sensor 8 is fixedly provided on the stirring blade 21. The temperature sensor 8 is electrically connected to a controller, and the controller is electrically connected to the water supply member of the water supply assembly 42. When the stirring blade 21 is working and the temperature in the reaction kettle body 1 is relatively high and the inside of the reaction kettle body 1 needs to be cooled down, the temperature sensor 8 transmits an electrical signal to the controller, and the controller controls the water supply member to start, and the water supply member conveys the cooling water to perform a cooling operation on the inside of the reaction kettle body 1.

[0041] The implementation principle of a glass-lined reaction kettle of the present invention is as follows: When it is necessary to process materials, first add the materials into the reaction kettle body 1. At this time, the materials at a corresponding height in the reaction kettle body 1 will squeeze the bearing plate 45, so that the bearing plate 45 at the corresponding height and the bearing plate 45 below will descend. The bearing plate 45 drives the sliding rod 46 and the extrusion block 47 to descend, stretches the first elastic member 481, and squeezes the sliding block 6, so that the sliding block 6 drives the connecting pipe 441 to slide in a direction away from the stirring shaft 2 and stretches the second elastic member 482. At this time, the connecting pipe 441 drives the connecting portion 444, the cooling blade 442, and the water return pipe 71 to slide. The water return pipe 71 slides in the stirring blade 21. The connecting portion 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 portion 444 is located in the fixed pipe 431 and the connecting portion 444 is communicated with the fixed pipe 431, and the water return pipe 71 is located in the pipe of the first water return ring 72;

[0042] Next, the stirring shaft 2 rotates, driving the stirring blades 21 to rotate. When the stirring blades 21 rotate, they can drive the connecting pipe 441, the rotating ring 43, the cooling blades 442, the water return pipe 71 and the first water return ring 72 to rotate. During the rotation of the connecting pipe 441, the rotating ring 43, the cooling blades 442, the water return pipe 71 and the first water return ring 72, the stirring effect on the material can be improved, making the stirring of the material more uniform;

[0043] Meanwhile, when the temperature inside the reaction kettle body 1 is relatively high and cooling is required for the inside of the reaction kettle body 1, the temperature sensor 8 transmits an electrical signal to the controller, and the controller controls the water supply component to start. The water supply component conveys cooling water, and the cooling water enters the water storage cavity 411 through the water supply pipe 421, and then sequentially enters the connecting part 444, the connecting pipe 441, the cooling blades 442, the water return pipe 71 and the cavity of the stirring blade 21 through the fixed pipe 431. The connecting pipe 441, the cooling blades 442, the water return pipe 71 and the stirring blade 21 are in full contact with the material, and efficient cooling operation is carried out on the material, thereby cooling the inside of the reaction kettle body 1. When the temperature of the cooling water is relatively high during use, the valve of the drain pipe 74 is opened, and the cooling water can be discharged through the drain pipe 74. Subsequently, the water supply component continues to convey the cooling water, thereby realizing the circulating operation of the cooling water;

[0044] When cooling is no longer required inside the reaction kettle body 1, the water supply component stops working at this time, and the drain pipe 74 discharges the cooling water. When the material is processed in the reaction kettle body 1 and completed, the material is discharged from the bottom end of the reaction kettle body 1. At this time, the material no longer presses on the bearing plate 45, and the first elastic member 481 and the second elastic member 482 release the elastic restoring force. The first elastic member 481 drives the sliding rod 46, the extrusion block 47 and the bearing plate 45 to reset, and the second elastic member 482 drives the sliding block 6, the connecting pipe 441, the connecting part 444, the cooling blades 442 and the water return pipe 71 to slide and reset. The connecting part 444 slides out of the fixed pipe 431, and the water return pipe 71 slides out of the pipe of the first water return ring 72 to reset. At the same time, the sealing piece 5 undergoes elastic deformation and resets, completing the processing operation of the material.
