Description

Technical Field

[0001] The invention relates to the technical field of spray drying, in particular to a powdered sodium silicate spray drying device. Background Art

[0002] Powdered sodium silicate, also known as powdered water glass, is a white or slightly light gray powder in the form of small particles. It is soluble in water and has strong adhesion, cold resistance, uniformity, and is extremely convenient to use, transport, and store. Therefore, it is widely used in production. Powdered sodium silicate can be produced by spray drying. Traditional spray drying is to spray the solution in a reactor in a mist form, and then introduce high-temperature water vapor to cause the water vapor and the mist solution to collide, thereby quickly evaporating the water of the product to be produced and obtaining a powdered product to be produced.

[0003] At present, in the process of drying and preparing powdered sodium silicate, the existing technology is to pass the mist sodium silicate raw material into the interior of the kettle, and then pass high-temperature gas into it, and use the high-temperature gas to dry it. The dried crystals will automatically fall to the bottom of the kettle for collection. This method has the following disadvantages; First, during the introduction of the mist sodium silicate raw material, because it is in a straight-through state, the raw material needs a long time to dry in order to evaporate the internal moisture before crystallization can be carried out, and the timeliness is low; Secondly, the misty sodium silicate raw material inside the kettle is in direct contact with the moisture and dust in the high-temperature gas, resulting in a high level of impurities in the final crystallized sodium silicate particles and low purity, which affects the quality of the sodium silicate crystals; Thirdly, the misty sodium silicate raw material crystallizes inside the kettle body. Due to the volume of the kettle body, "fog" may appear and crystallize at the same time, forming blocky crystalline particles. At this time, subsequent processes are required to be processed, resulting in poor crystallized particles. Therefore, a powdered sodium silicate spray drying device is proposed to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-Figure 8A powdered sodium silicate spray drying device comprises a kettle body 1; a feed pipe 2, which is used to provide an input channel for misty sodium silicate particles; a drying component 3, which is used to circulate and dry the misty sodium silicate entering the kettle body 1; a shaking component 4, which is used to shake off the crystallized particles on the drying component 3; and a discharging component 5, which is used to automatically and quantitatively discharge the crystallized sodium silicate particles and to crush, screen and filter the blocky crystal particles.

[0021] In this embodiment, the drying assembly 3 includes an air inlet pipe 301 and an air outlet pipe 302, both of which are installed on the kettle body 1. The bottom of the air inlet pipe 301 is connected to the air box 303, and the air box 303 is arranged inside the kettle body 1. The bottom of the air outlet pipe 302 is connected to the air box 303. A spiral blade 306 with a spiral structure is arranged in the middle of the air box 303. The mist sodium silicate particles pass through the spiral blade 306 and are indirectly dried by the high-temperature airflow inside the air box 303. The high-temperature gas is injected into the air box 303 through the air inlet pipe 301, and the air box 303 is filled with high-temperature gas and heated. Then, the mist sodium silicate raw material enters the interior of the kettle body 1 and passes through the middle of the air box 303. At this time, the radiant heat of the air box 303 is used to dry the raw material, and then the sodium silicate is dried and crystallized. The whole scheme uses the principle of indirect radiation to dry sodium silicate, which directly avoids direct contact between water vapor and impurities in high-temperature gas and mist sodium silicate. The mist sodium silicate does not flow in a straight-through manner in the traditional way, but in a spiral rotation flow, because the spiral blades 306 directly define the flow channel of the airflow, so that the airflow will rotate downward in circles. Through this flow, the path length of the raw material in the flow process can be increased, so that the drying time of the mist sodium silicate can be prolonged in a limited space.

[0022] Furthermore, a plurality of stepped corrugated grooves 304 are provided on the inner side of the air box 303, and a return air cavity 305 is provided inside the kettle body 1, and the top of the return air cavity 305 is connected to the top of the spiral blade 306 through a pipe. The plurality of corrugated grooves 304 can increase the heat radiation area, which is similar to the principle of a "heat sink", and the intensity of heat radiation will be increased accordingly, thereby ultimately improving the drying effect of the misted sodium silicate raw material.

[0023] Furthermore, the shaking assembly 4 includes a driving motor 401, which is installed on the top of the kettle body 1. The output end of the driving motor 401 is connected to a rotating shaft 402, the bottom of the rotating shaft 402 is connected to a rotating seat 403, a pressing wheel 405 is connected to the rotating seat 403, a pressing block 404 is arranged on the rotating path of the pressing wheel 405, the top of the pressing block 404 is connected to a lifting seat 407, the top of the lifting seat 407 is connected to the spiral blade 306, the inside of the spiral blade 306 is slidably connected to a sleeve 406 through a keyway, and the top of the sleeve 406 is fixedly connected to the kettle body 1. There are two pressing blocks 404 and two pressing wheels 405, and the two pressing blocks 404 and the pressing wheels 405 are symmetrically distributed with the center of the lifting seat 407 as the symmetry axis, the bottom of the lifting seat 407 is connected to a support spring 408, and the bottom of the support spring 408 is connected to the rotating seat 403. The rotation of the driving motor 401 will drive the rotation of the rotating shaft 402, and then drive the rotation of the rotating seat 403, and the rotating seat 403 will drive the pressure wheel 405 connected above to rotate, and each rotation of the pressure wheel 405 will contact with the pressure block 404 above, thereby pushing the lifting seat 407 to move up and shake, and the lifting seat 407 will move up and drive the spiral blade 306 to move up, and when the pressure wheel 405 is separated from the pressure block 404, it will be stretched by gravity and the support spring 408, and it will drive the spiral blade 306 to move down, so the whole process of rotation and shaking is realized, and then the particles that have been crystallized in the circulation channel are shaken off to avoid direct attachment to the spiral blade 306.

[0024] In addition, the discharge assembly 5 includes two loading seats 501, and a fixing plate 502 is slidably connected between the two loading seats 501, the fixing plate 502 is fixed to the inner wall of the kettle body 1, the loading seat 501 is slidably connected to the inner wall of the kettle body 1, the bottom of the loading seat 501 is connected to a compression spring 506, the bottom of the compression spring 506 is connected to a connecting seat 507, the connecting seat 507 is fixed on the kettle body 1, and a locking device is provided on the loading seat 501, and a support rod 504 is connected to the loading seat 501 through a bracket 503, and a blocking column 505 is connected to the top of the support rod 504, and the blocking column 505 is slidably connected to the inside of the feed pipe 2. At this time, the influence of gravity will press down the compression spring 506 at the bottom, and the loading seat 501 will be separated from the fixing plate 502 when pressed down, revealing the gap in the middle. At this time, the sodium silicate crystal particles will fall from the gap in the middle to the filter screen 515 at the bottom. In order to avoid the continued intake of misty sodium silicate raw materials during discharge, a support rod 504 is provided. When the loading seat 501 moves downward, the blocking column 505 on the support rod 504 will be driven to move downward through the connection of the bracket 503, and the blocking column 505 will directly block the bottom capillary position of the feed pipe 2 when it moves downward. Therefore, the misty sodium silicate raw material will be directly blocked and cannot enter the interior of the kettle body 1, thereby preventing the misty sodium silicate airflow from entering the bottom accommodation space of the kettle body 1.

[0025] In addition, the positioning device includes a socket 510, one side of which is connected to a clamping spring 512, and the other side of the socket 510 is inserted into a slot 511 provided on the material carrier 501, and the socket 510 is slidably connected to the kettle body 1. As the particles are continuously loaded, the material carrier 501 will be driven downward by gravity, and because the elastic force of the clamping spring 512 cannot support the clamping of the socket 510 at this time, the socket 510 will be squeezed by gravity to slide to the left, thereby squeezing the clamping spring 512 and finally forming a trip. The main purpose of the socket 510 is to limit the unloaded position of the material carrier 501. When a certain weight of crystal particles is loaded, the socket 510 will not be able to be clamped, and the process of automatically pressing down and discharging is realized without the need for manual control by the operator.

[0026] It is worth noting that the connecting seat 507 is rotatably connected to a rotating frame 508 via a rotating shaft, a sphere is connected to the top of the rotating frame 508, a torsion spring is arranged inside the rotating frame 508, one end of the torsion spring is connected to the rotating frame 508, and the other end of the torsion spring is connected to the connecting seat 507, and a push rod 509 is connected to the surface of the rotating seat 403, and the push rod 509 abuts against the push rod 509 during rotation. The rotation of the rotating seat 403 drives the push rod 509 to rotate. At this time, the push rod 509 rotates and contacts and squeezes the bottom of the rotating frame 508, driving the rotating frame 508 to rotate a certain angle. After that, after the push rod 509 detaches from the rotating frame 508, it is reset by the torsion spring, which provides an instantaneous elastic force and drives the ball on the rotating frame 508 to hit the bottom of the loading seat 501, forming a knocking vibration. Therefore, the crystal particles on the loading seat 501 will be continuously subjected to the knocking vibration and fall from the gap between the two loading seats 501 to the filter screen 515, avoiding the situation that the crystal particles on the loading seat 501 have a large adhesion and are not easy to slide.

[0027] It is worth noting that a filter screen 515 is slidably connected inside the kettle body 1, and the filter screen 515 is connected to the lifting seat 407 through a supporting connecting rod 517. A T-shaped slide 513 is provided on the rotating seat 403, and a powder pressing wheel 518 is rotatably connected to the T-shaped slide 513. Considering that block crystals may appear during crystallization, a powder pressing wheel 518 is provided. When the rotating seat 403 rotates, the powder pressing wheel 518 is driven to rotate around the center of the rotating seat 403 through the connection of the T-shaped slide 513. Therefore, at this time, the powder pressing wheel 518 will crush and pulverize the block crystals on the filter screen 515, and the crushed crystal particles will gradually fall from the filter screen 515 to the accommodation space at the bottom of the kettle body 1.

[0028] In addition, a toothed ring 516 is fixedly connected to the filter screen 515, the center of the powder pressing wheel 518 is connected to the rotating gear 514 through a shaft, the surface of the rotating gear 514 is meshed with the toothed ring 516, the T-shaped slide 513 is rotatably connected to the powder pressing wheel 518, and the right end of the T-shaped slide 513 is slidably connected to the rotating seat 403 through a T-shaped groove. When the powder pressing wheel 518 rotates, it also drives the rotating gear 514 to mesh and rotate on the toothed ring 516. When the powder pressing wheel 518 rotates in a circle with the rotating seat 403, it can also rotate with the center of the powder pressing wheel 518 itself, and finally the crystal particles are crushed to ensure the consistency of the crystal particles in the accommodating space.

[0029] In addition, the bottom of the rotating shaft 402 is connected to a stirring rod 6, and the stirring rod 6 is located below the filter 515. Through the setting of the stirring rod 6, the particles in the accommodating space can be stirred at all times to avoid subsequent long-term extrusion and the agglomeration caused again. The setting of the stirring rod 6 can also avoid the situation where the crystal particles are piled up and stuck during discharging, and the material cannot be discharged directly. The setting of the stirring rod 6 can always keep the looseness of the crystal particles.

[0030] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0031] The working principle is that the misty sodium silicate raw material needs to be injected from the inside of the feed pipe 2 through the equipment pipeline, and at the same time, the high-temperature gas is injected into the inside of the air box 303 through the air inlet pipe 301, so that the inside of the air box 303 is filled with high-temperature gas and the air box 303 is heated. Then the misty sodium silicate raw material enters the inside of the kettle body 1 and passes through the middle of the air box 303. At this time, the radiation heat of the air box 303 is used to dry the raw material, and then the sodium silicate is dried and crystallized. The whole scheme uses the principle of indirect radiation to dry the sodium silicate, which directly avoids the direct contact between the water vapor and impurities in the high-temperature gas and the misty sodium silicate. The mist sodium silicate does not flow in a straight-through manner in the traditional way, but in a spiral rotation circulation, because the spiral blades 306 directly define the flow channel of the airflow, so that the airflow will rotate downward in circles. Through this flow, the path length of the raw material in the flow process can be increased, so that in a limited space, the drying time of the mist sodium silicate can be prolonged. Therefore, the entire mist sodium silicate is basically completely dried when it flows to the bottom space, and the formed crystal particles will adhere to the spiral blades 306, or fall on the bottom of the material carrier 501, even if it is not completely dried. The dried sodium silicate mist will flow back to the top of the spiral blade 306 through the return air chamber 305, and form a return channel according to the extrusion of the airflow to achieve the process of drying again. At this time, the driving motor 401 will rotate synchronously, and the rotation of the driving motor 401 will drive the rotation of the rotating shaft 402, and then drive the rotation of the rotating seat 403, and the rotating seat 403 will drive the pressure wheel 405 connected above to rotate, and the pressure wheel 405 will contact with the pressure block 404 above every rotation, thereby pushing the lifting seat 407 to move upward. Because the height of the pressure wheel 405 is unchanged, and the pressure block 404 is fixedly connected to the lifting seat 407, the pressure wheel 405 will contact the pressure block 404 every time it rotates. It can be understood that a pressure block 404 is a "convex point" under the lifting seat 407. When the pressure wheel 405 rotates and contacts the "convex point", it will push up the position of the "convex point", thereby driving the lifting seat 407 to move upward, and the upward movement of the lifting seat 407 will drive the spiral blade 306 to move upward. After the pressure wheel 405 is separated from the pressure block 404, it is stretched by gravity and the support spring 408. The spiral blade 306 will be driven to move downward, so the whole body will realize the process of rotation and shaking. Due to the influence of drying, the misty sodium silicate crystal particles attached to the spiral blade 306 will be continuously shaken up and down, and follow the spiral blade 306 to roll to the bottom of the loading seat 501. The upper surface of the loading seat 501 is a V-shaped centralized structure. Therefore, as the particles are continuously loaded, the loading seat 501 will be driven to move downward under the influence of gravity. At this time, because the elastic force of the clamping spring 512 cannot support the clamping of the socket 510, the socket 510 will be squeezed by gravity to slide to the left.The clamping spring 512 is squeezed and finally released. At this time, the compression spring 506 at the bottom is pressed down by the influence of gravity, and the loading seat 501 is pressed down to disengage from the fixing plate 502, revealing the gap in the middle. At this time, the sodium silicate crystal particles will fall from the gap in the middle to the filter screen 515 at the bottom. In order to avoid the continued intake of the misty sodium silicate raw material during discharge, a support rod 504 is provided. When the loading seat 501 moves downward, the blocking column 505 on the support rod 504 will be driven to move downward through the connection of the bracket 503. The downward movement of the blocking column 505 will directly block the bottom capillary position of the feed pipe 2. Therefore, the misty sodium silicate raw material will be directly blocked and cannot enter the interior of the kettle body 1, thereby preventing the misty sodium silicate airflow from entering the bottom accommodation space of the kettle body 1. The crystal particles on the material carrier 501 are also affected by the rotation of the rotating seat 403, which drives the push rod 509 to rotate. At this time, the push rod 509 rotates and contacts and squeezes the bottom of the rotating frame 508, driving the rotating frame 508 to rotate a certain angle. After that, after the push rod 509 is separated from the rotating frame 508, it is reset by the torsion spring, which provides an instantaneous elastic force and drives the ball on the rotating frame 508 to hit the bottom of the material carrier 501, forming a knocking vibration. Therefore, the crystal particles on the material carrier 501 are constantly affected by the knocking vibration and fall out of the gap between the two material carriers 501. After the crystal particles on the material carrier 501 have fallen off, the gravity decreases. At this time, the compression spring 506 will continue to push the material carrier 501 upward, and then push the slot 511 on the material carrier 501 to engage with the socket 510, thereby providing an automatic discharging process for the next cycle. Therefore, after the material carrier 501 moves up, the blocking column 505 will move up and enter the larger diameter pipeline in the middle of the feed pipe 2. Therefore, the misty sodium silicate raw material will enter the interior of the kettle body 1 from the channel of the feed pipe 2 again for another drying operation. The crystal particles falling on the filter screen 515 will be screened and filtered by the setting of the filter screen 515, and when the lifting seat 407 moves up and down, the filter screen 515 will be driven to shake up and down through the connection of the supporting connecting rod 517, so that the shaking screening process is realized, and finally uniform crystal particles will fall to the bottom accommodation space of the kettle body 1. Considering that block crystals may appear during crystallization, a powder pressing wheel 518 is set. When the rotating seat 403 rotates, it will drive the powder pressing wheel 518 to rotate through the connection of the T-shaped slide 513. The center of the rotating seat 403 rotates, so the powder pressing wheel 518 will crush the block crystals on the filter screen 515. Considering that the filter screen 515 is in a state of shaking up and down, the T-shaped slide 513 slides up and down on the rotating seat 403, and there is no interference between the shaking and the rotating crushing. When the powder pressing wheel 518 rotates, it will also drive the rotating gear 514 to mesh and rotate on the gear ring 516. Therefore, when the powder pressing wheel 518 rotates in a circle with the rotating seat 403, it can also rotate at the center of the powder pressing wheel 518 itself.Finally, the crystal particles are rolled to ensure the consistency of the crystal particles in the accommodation space.
