Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a novel reactor for silicate production. Background Art

[0002] In the modern industrial system, silicate materials are widely used in many fields such as construction, glass, ceramics, and refractory materials, and are indispensable basic materials for the development of the national economy. As the core equipment for silicate production, the performance of the reactor is directly related to the quality of the product, production efficiency, and economic benefits of the enterprise. With the continuous advancement of science and technology and the growing market demand, traditional reactors for silicate production have gradually exposed many problems and are difficult to meet current production requirements.

[0003] Generally speaking, when silicate acid is used to prepare special composite materials, the materials need to be put in with priority. Usually, organic additives are added after the silicate acid has reacted and melted to ensure that they play a specific role. Some large industrial reactors are equipped with a piping system for adding materials during the reaction process, and the organic additives are transported to the reactor using pressure difference or pumping principles.

[0004] According to Chinese patent publication number CN219804644U, the patent provides a reactor for the production of silicate modified stock solution, which includes a reactor body and bottom support legs. A feed port is set at the center of the bottom of the reactor body, a first motor is installed at the center of the top, and a feed port is set on one side of the top. The output shaft of the first motor is connected to the stirring shaft, and an L-shaped stirring rod is fixed on the stirring shaft and an auxiliary stirring device is provided. The surface of the stirring rod is evenly provided with flow holes. During stirring, the auxiliary stirring device stirs the material in different directions, and the spiral blade lifts the bottom material upward to promote material mixing.

[0005] However, organic additives contain impurities and polymers, which makes it difficult to supervise the pipeline insulation measures and easily lead to pipeline blockage. Organic additives are also corrosive and easily cause the risk of pipeline leakage. At the same time, the pressure difference control conveying pressure will change during the reaction due to reaction heat release and material changes, which leads to unstable organic additive delivery speed and affects the reaction process, which brings inconvenience and certain safety risks to the secondary feeding of materials. Therefore, a new reactor for silicate production is proposed to solve the above problems. Summary of the invention

[0008] Preferably, the frame is a cylindrical structure with an opening at the bottom, the outer wall of the frame is surrounded by three notches, and the bottom of the frame is fixedly connected to the top of the top cover of the kettle body and is centrally arranged.

[0009] Preferably, the feeding part includes a motor, which is installed on the top of the frame, and the output shaft of the motor is fixedly connected to a rotating shaft, which movably passes through the top of the frame and extends downward, and a feeding cylinder is fixedly connected to the extended end of the rotating shaft, which movably passes through the top cover of the kettle body and extends to the inside of the kettle body, and the outer wall of the feeding cylinder is connected to a feeding port, and the feeding port is located between the inner walls of the frame.

[0010] Preferably, the centrifugal part includes a thermal insulation tank, which is a conical structure, and the top outer wall of the thermal insulation tank is a conical structure. A through hole is opened on the top of the conical outer wall of the thermal insulation tank, and the inner wall of the through hole is fixedly connected to the outer wall of the extended end of the feed barrel.

[0011] Preferably, six ball holes are opened around the conical outer wall of the insulation tank, and each of the two sides of the ball hole is fixedly connected with a support rod, and each of the support rods is arranged to be inclined downward. The two ends of the support rods on each ball hole are fixedly connected with a support plate, and the inner wall of each ball hole is abutted with a blocking ball, and each blocking ball is slidably connected between two adjacent support rods, and each blocking ball is elastically connected with a spring between the adjacent support plate.

[0012] Preferably, six stirring rods are connected around the conical outer wall of the insulation tank, and the six stirring rods and the six ball holes are arranged alternately.

[0013] Preferably, the oscillation part includes a connecting rod, which is fixedly connected to the conical outer wall of the insulation tank and arranged at an angle, and an insertion rod is fixedly passed through the end of the connecting rod, and a U-shaped piece is arranged on the insertion rod, and two ear ends of the U-shaped piece are respectively rotatably mounted on the two ends of the insertion rod, and torsion springs are elastically connected between the two ear ends of the U-shaped piece and the end of the connecting rod, and the outer wall of the U-shaped piece is fixedly connected to a vibration rod.

[0014] Preferably, there are three oscillating parts, which are installed around the conical outer wall of the temperature-isolating tank and arranged in an array.

[0015] Preferably, the bottom of the kettle body is a conical structure, and there are six protrusions, which are connected to the conical inner wall of the bottom of the kettle body around, and the ends of the three vibration rods in the three oscillation parts are all in contact with the conical inner wall of the bottom of the kettle body.

[0016] Preferably, ear hooks are installed on both sides of the outer wall of the kettle body, a discharge port is connected to the bottom of the kettle body, a loading port is connected to one side of the outer wall of the kettle body, and a pressure relief valve, a pressure gauge and a thermometer are respectively installed on the top cover of the kettle body.

[0017] (III) Beneficial effects: Compared with the prior art, the present invention provides a new type of reactor for silicate production, which has the following beneficial effects: 1. The new reactor used for silicate production adopts a feeding part and a centrifugal part to solve the problems of pipeline blockage and leakage. Traditional reactors use pipelines to transport organic additives. Because the additives contain impurities, polymers and are corrosive, they are easy to cause pipeline blockage and leakage. The reactor in this case adopts a design that combines a feeding part and a centrifugal part. The motor drives the rotating shaft and the feeding cylinder to pre-store the organic additives in the insulation tank. The blocking ball and spring structure of the insulation tank can effectively prevent leakage when the additives do not meet the release conditions. There is no need for long-term pipeline transportation, which avoids the accumulation of impurities and polymers to block the pipeline, fundamentally solving the disadvantages of traditional pipeline transportation and ensuring safe and stable production.

[0018] 2. The new reactor used in silicate production adopts a stable organic additive delivery speed. Traditional reactors rely on pressure difference to control the delivery of organic additives. Pressure changes during the reaction process will make the delivery speed unstable and affect the reaction process. The reactor in this case uses the motor speed control to rotate the insulation tank and uses centrifugal force to release organic additives. During the liquefaction of silicate hydrochloric acid, the motor adjusts the speed according to the reaction time. During liquefaction and molding, the additives are quickly thrown out by high-speed rotation. In the later stage of the reaction, the mixed liquid is prevented from backflowing. The release rhythm of the additives is accurately controlled without being disturbed by changes in reaction pressure, ensuring stable delivery speed and smooth reaction.

[0019] 3. The new reactor used in silicate production adopts the method of enhancing the material mixing effect. The oscillating part cooperates with the convex block at the bottom of the reactor body to oscillate the material. When the vibration rod rotates in the insulation tank, it changes its angle each time it passes through the convex block and resets under the action of the torsion spring, generating high-frequency micro-vibrations on the material deposited at the bottom, intensifying the relative movement of the material particles, breaking the agglomeration state, and making the material more fully dispersed. During the stirring process, the stirring rod, support rod and connecting rod also work together with the oscillation to further enhance the mixing effect and create favorable conditions for full reaction.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-7 The present invention provides a technical solution: a new type of reactor for silicate production, comprising a reactor body 1, a frame 2 in this case is installed on the top cover of the reactor body 1, a feeding part 3 in this case is installed on the frame 2, and is used to put and transport organic additives, a centrifugal part 5 in this case is installed on the feeding part 3, and the organic additives are released from the inside of the reactor body 1 through stirring centrifugal force, an oscillating part 7 in this case is installed on the centrifugal part 5, and the silicic acid in the reaction is oscillated at an adaptive stirring speed, and a protrusion 8 in this case is installed on the inner wall of the bottom of the reactor body 1.

[0024] In this embodiment, the frame 2 of this case is a cylindrical structure and is open at the bottom. Three notches are opened around the outer wall of the frame 2. The bottom of the frame 2 is fixedly connected to the top of the top cover of the kettle body 1 and is centrally arranged. In order to replace the traditional pressure delivery pipeline, reduce the cost of loading organic additives and improve the loading safety, the feeding part 3 of this case includes a motor 31. The motor 31 is installed on the top of the frame 2. The output shaft of the motor 31 is fixedly connected to the rotating shaft 32. The rotating shaft 32 movably passes through the top of the frame 2 and extends downward. A feeding barrel 33 is fixedly connected to the extended end of the rotating shaft 32. The feeding barrel 33 movably passes through the top cover of the kettle body 1 and extends to the inside of the kettle body 1. The outer wall of the feeding barrel 33 is connected to a feeding port 34. The feeding port 34 is located between the inner walls of the frame 2. The feeding port 34 is rotated to the notch position of the frame 2 to load the organic additive.

[0025] It is worth noting that in order to pre-store the organic additives in the reactor, automatically release them through a suitable stirring speed and mix them with the hydrosilicic acid, the centrifugal part 5 of the present case includes an insulation tank 51, and the insulation tank 51 uses an insulation material, such as polycrystalline mullite fiber of ceramic fiber type as an insulation layer of the inner wall of the insulation tank 51, which is used to reduce the temperature change inside the reactor and affect the physical properties of the organic additives in advance. The insulation tank 51 is a conical structure, and the top outer wall of the insulation tank 51 is a conical surface structure. A through hole 52 is opened on the top of the conical outer wall of the insulation tank 51, and the inner wall of the through hole 52 is fixedly connected to the outer wall of the extended end of the feed barrel 33. The conical outer wall of the insulation tank 51 is surrounded by six ball holes 53, each of which is provided with a through hole 52. Both sides of each ball hole 53 are fixedly connected with support rods 54, each support rod 54 is set to be tilted downward, and the ends of the two support rods 54 on each ball hole 53 are fixedly connected with support plates 55. The inner wall of each ball hole 53 is abutted with a blocking ball 56, and the blocking ball 56 is used to seal the ball hole 53 to prevent the organic additive from leaking prematurely and to prevent silicic acid from accidentally entering the insulation tank 51. Each blocking ball 56 is slidably connected between two adjacent support rods 54, and each blocking ball 56 is elastically connected to the adjacent support plates 55 with a spring 57. Six stirring rods 6 are connected around the conical outer wall of the insulation tank 51, and the six stirring rods 6 are staggered with the six ball holes 53.

[0026] It is worth noting that in order to further enhance the mixing effect of silicic acid and organic additives and accelerate the chemical reaction, the oscillating part 7 in this case includes a connecting rod 71, which is fixedly connected to the conical outer wall of the insulation tank 51 and is tilted. The end of the connecting rod 71 is fixedly penetrated by an insertion rod 72, and a U-shaped piece 73 is provided on the insertion rod 72. The two ear ends of the U-shaped piece 73 are respectively rotatably sleeved on the two ends of the insertion rod 72. The two ear ends of the U-shaped piece 73 and the end of the connecting rod 71 are elastically connected with a torsion spring. The outer wall of the U-shaped piece 73 is fixedly connected to a vibration rod 74, and the vibration rod 74 is reset by the torsion spring. There are three oscillating parts 7, which are mounted around the conical outer wall of the insulation tank 51 and arranged in an array. The bottom of the kettle body 1 is a conical structure. There are six protrusions 8, six The convex block 8 is connected to the conical inner wall at the bottom of the kettle body 1, and the ends of the three vibration rods 74 in the three oscillating parts 7 are all in contact with the conical inner wall at the bottom of the kettle body 1. Ear hooks 4 are installed on both sides of the outer wall of the kettle body 1. The bottom of the kettle body 1 is connected to a discharge port 9, and the raw materials are discharged from the discharge port 9 after the reaction is completed. A loading port 10 is connected to one side of the outer wall of the kettle body 1. Pressure relief valves are installed on the top cover of the kettle body 1. When the pressure in the reactor exceeds the set safety value, the pressure relief valve automatically opens to discharge gas or liquid, reduce the pressure, and prevent the reactor from over-pressure explosion. The pressure gauge is used to monitor the pressure in the reactor in real time, and the thermometer is used to measure the temperature of the material in the reactor to ensure that the reaction is carried out within a suitable temperature range to prevent the reaction effect from being affected or a safety accident from being caused by too high or too low temperature.

[0027] Working principle: add a suitable amount of hydrochloric acid from the feed port 10 into the kettle body 1, the height of the hydrochloric acid is lower than the position of the ball hole 53, and the feed port 34 is driven by the motor 31 to rotate the shaft 32, and drive the feed cylinder 33 to rotate to the notch position of the frame 2, and add a suitable amount of organic additives from the feed port 34, so that the organic additives enter the insulation tank 51 for pre-storage, and the motor 31 works slowly, so that the feed cylinder 33 drives the insulation tank 51 to rotate slowly, and the stirring rod 6 cooperates with the support rod 54 and the connecting rod 71 to synchronously perform initial stirring of the hydrochloric acid. The centrifugal force in the insulation tank 51 under slow rotation is weak, and the problem of internal organic additives climbing and overflowing will not be caused.

[0028] The temperature in the kettle body 1 rises to gradually liquefy the silicic acid, and at the same time, the motor 31 increases its speed progressively according to the reaction time. When the liquefied silicic acid is formed, the motor 31 rotates at a high speed. At this time, under the influence of strong centrifugal force, the blocking ball 56 will slide obliquely downward along the support rod 54 and away from the ball hole 53. At the same time, the organic additives in the insulation tank 51 will climb upward along the conical inner wall of the tank body under the influence of strong centrifugal force, and will be ejected from the ball hole 53 into the kettle body 1 to mix with the liquefied silicic acid until the organic additives are completely dried out of the insulation tank 51. After the motor 31 is switched from high speed to slow speed according to the reaction time, the elastic force of the spring 57 pushes the blocking ball 56 to reset and block the ball hole 53 to prevent the silicic acid mixed liquid from accidentally entering the insulation tank 51 during stirring.

[0029] During the rotation of the insulation tank 51, the vibration rod 74 performs a circular motion, and changes its angle each time it passes through the protrusion 8, and resets to fit the bottom inner wall of the kettle body 1 under the elasticity of the torsion spring, so that the vibration rod 74 forms a continuous ups and downs, thereby oscillating the hydrochloric acid and organic additives deposited at the bottom, generating high-frequency micro-vibrations to make the relative movement between the material particles more intense, further breaking the agglomeration state of the materials, allowing the materials to be more fully dispersed and mixed, and cooperating with the stirring effect of the stirring rod 6, the support rod 54 and the connecting rod 71, further accelerating the chemical reaction, promoting mass transfer and heat transfer, improving the product microstructure, and reducing bubbles and impurities.
