Description

Technical Field

[0001] The invention relates to the technical field of sodium pyroantimonate particle production, and in particular to a high-efficiency and environmentally friendly drying device for sodium pyroantimonate particle production. Background Art

[0002] Sodium pyroantimonate granules are inorganic salt compounds of antimony. They are produced by using antimony products such as antimony oxide through alkali and hydrogen peroxide. They appear as white powder and have two types: granular crystals and equiaxed crystals. They have a melting point of 1200°C and a boiling point of 1400°C. They are soluble in tartaric acid, sodium sulfide solution, and concentrated sulfuric acid, slightly soluble in alcohol and silver salts, insoluble in acetic acid, dilute alkali and dilute inorganic acids, insoluble in cold water, and have good chemical stability.

[0003] Sodium pyroantimonate particles are mainly used as clarifiers and defoamers for photovoltaic solar glass, black and white, and color display screen kinescope glass. The process flow is as follows: antimony trioxide, water, and sodium hydroxide are added to a reactor to perform a constant temperature slurry reaction; after sufficient slurrying, hydrogen peroxide is added dropwise to perform an oxidation reaction; after the oxidation reaction is completed, stirring is stopped, the jacket circulating water valve is opened, the mixture is allowed to stand, and the mixture is cooled to 60°C for crystallization and granulation; finally, the mixture is dried until the moisture content is less than 0.3%, thereby obtaining a finished sodium antimonate product.

[0004] At present, when drying the crystal particles of sodium antimonate pyrophosphate, stirring drying is generally adopted, which is similar to an environmentally friendly quartz sand drying device with application publication number CN113390248 A, including a drying box, a four-pronged air guide pipe is connected to the right side of the drying box, and a combustion furnace is connected to the end of the four-pronged air guide pipe, and a four-pronged exhaust pipe is connected to the left side of the drying box, and an induced draft fan is connected to the end of the four-pronged exhaust pipe. The crystal particles of sodium antimonate pyrophosphate are placed in the drying box, the particles in the drying box are stirred, and hot air is added during the stirring process to achieve drying. In this drying method, first, during the stirring process of the crystal particles of sodium antimonate pyrophosphate, it is easy for the inside of the particles that are adhered together to be difficult to be stirred, so that the speed of internal drying is slow, the efficiency is low, and the problem of incomplete drying is also prone to occur.

[0005] At the same time, the existing devices have a certain heating and drying efficiency for the internal sodium antimonate pyrophosphate particles. However, due to the different drying degrees of the sodium antimonate pyrophosphate particles, the drying time and drying degree required for subsequent drying are different. Therefore, the existing devices are unable to adaptively adjust their subsequent heating efficiency according to the drying degree of the sodium antimonate pyrophosphate particles, which easily causes some sodium antimonate pyrophosphate particles to not be dried thoroughly, increases the number of drying cycles, increases energy consumption losses, and reduces drying efficiency.

[0006] Moreover, as the angle of the material guiding and drying plate changes, the length of the mixing brush plate cannot change adaptively, which results in the mixing brush plate and the top of the material guiding and drying plate being unable to always maintain mutual extrusion, contact and stirring, or the degree of extrusion between the mixing brush plate and the top of the material guiding and drying plate is too great, causing damage to the mixing brush plate, thereby reducing the stirring and drying effect of the sodium antimonate pyrophosphate particles flowing on the top of the material guiding and drying plate.

A controller is provided on one side of the drying box 1. The controller electrically controls various electrical components. A first motor 2 is provided on one side of the top of the drying box 1. A material opening is opened in the middle of the top of the drying box 1, and a box cover 3 is hinged at the material opening. A handle is provided on the box cover 3. The handle is provided to facilitate opening the box cover 3 and pouring the sodium antimonate pyrophosphate particles into the drying box 1 along the material opening.

[0039] The interior of the drying box 1 is set as a drying chamber 6 and a lifting chamber 7 from left to right. The volume of the drying chamber 6 is much larger than that of the lifting chamber 7. The inner walls on both sides of the drying chamber 6 are rotatably connected with a plurality of groups of material guiding drying plates 10 arranged in a staggered and inclined manner through a rotating shaft. The inclination direction of the material guiding drying plates 10 is downward from the inner wall of the drying chamber 6 to the middle of the drying chamber 6, so as to realize that the sodium antimonate pyrophosphate particles roll from one end of the material guiding drying plate 10 to the other end, and finally roll onto the next material guiding drying plate 10. The lower end of the interior of the drying chamber 6 is provided with a material guiding bottom slope 12 for separation. A lifting assembly connected to the first motor 2 is provided in the lifting chamber 7. The first motor 2 drives the lifting assembly to rotate and lift the sodium antimonate pyrophosphate particles to realize the cyclic drying of the sodium antimonate pyrophosphate particles. A lifting discharge port 8 and a lifting feed port 9 connected to the drying chamber 6 are respectively provided at the upper and lower ends of one side of the lifting chamber 7, so as to facilitate the particles to enter from the lifting feed port 9 and roll out from the lifting discharge port 8.

[0040] The lower end of the lifting chamber 7 is through-set and used for unloading. A pull-out material baffle plate 5 is provided at the opening of the lifting chamber 7. The pull-out material baffle plate 5 is slidably installed on the legs at the bottom end of the drying box 1, and a handle is provided to facilitate opening the bottom end of the lifting chamber 7.

[0041] The lower part of the guide bottom slope 12 is set as an equipment cavity 13. The upper end of the guide bottom slope 12 is inclined to facilitate the rolling of the sodium antimonate pyrophosphate particles. Two groups of mixing components 11 are arranged above each guide drying plate 10 and the guide bottom slope 12. The mixing components 11 stir the sodium antimonate pyrophosphate particles being dried during rolling to accelerate the progress of drying. The guide drying plate 10 and the guide bottom slope 12 are both provided with an inner cavity 24. The equipment cavity 13 is provided with a blast heating box 14. The blast heating box 14 is composed of a blower and a heating pipe. The heating pipe is installed at the air outlet of the blower. The blast heating box 14 heats the blown air to enter the air outlet. Hot air is sent into the drying box 1 to dry the sodium antimonate particles. A second motor 15 is provided in the equipment cavity 13. A first transmission member 18 is connected between the output shaft of the second motor 15 and multiple groups of mixing components 11 on the same side. A second transmission member 19 is connected between the two mixing components 11 above each material guiding drying plate 10. The first transmission member 18 and the second transmission member 19 enable the second motor 15 to drive all the mixing components 11 to work together. The air outlet of the blast heating box 14 is connected to the air outlet pipe 17 in the inner cavity 24 and the drying cavity 6, thereby realizing the delivery of hot air into the drying box 1.

[0042] The lifting component includes a lifting shaft fixedly connected to the output shaft of the first motor 2, and a lifting auger 16 is provided on the outer surface of the lifting shaft. The lifting chamber 7 is a columnar structure, and the outer side of the lifting auger 16 is in close contact with the inner wall of the lifting chamber 7. When the first motor 2 drives the lifting auger 16 to rotate forward, the lifting auger 16 can lift the sodium antimonate pyrophosphate particles from the bottom to the top, and when reversing, it can accelerate the discharge of the sodium antimonate pyrophosphate particles.

[0043] A bearing seat is provided at the bottom of the lifting auger 16, and a connecting rod is provided on the peripheral side of the bearing seat. The other end of the connecting rod is fixedly connected to the inner wall of the lifting chamber 7. The lifting feed port 9 is connected to the bottom end of the top surface of the material guide bottom slope 12. When discharging is required, it is only necessary to open the pull-out baffle plate 5, and the material in the lifting chamber 7 is discharged along the bottom. The lifting feed port 9 is located above the bottom end of the lifting auger 16 in the lifting chamber 7 to prevent the sodium antimonate particles entering the lifting chamber 7 from directly flowing out from the bottom end of the lifting chamber 7, so that the lifting effect is better.

[0044] A first heat-conducting hose 20 is connected between the inner cavities 24 of two adjacent material-conducting drying plates 10 and between the inner cavities 24 of the material-conducting drying plate 10 located at the bottom and the material-conducting bottom slope 12. The length of the first heat-conducting hose 20 can be appropriately changed, so that when the material-conducting drying plate 10 rotates inside the drying chamber 6, its heat-conducting performance will not be affected. The interiors of several material-conducting drying plates 10 and the material-conducting bottom slope 12 are connected, and a second heat-conducting hose 20 is connected between the top of the material-conducting drying plate 10 located at the top and the drying chamber 6. The heat-conducting hose 22 connects the material-conducting drying plate 10 with the drying chamber 6. A return pipe 21 is connected between the lower end of the drying chamber 6 and the air inlet of the blast heating box 14, so that the dried air can be refluxed through the return pipe 21 to accelerate the flow rate of the air in the drying box 1, thereby improving the drying effect. Specifically, the first heat-conducting hose 20 is connected between the bottom end of the inner cavity 24 of the material-conducting drying plate 10 and the top end of the inner cavity 24 of the material-conducting bottom slope 12, as well as between the head and tail of two adjacent material-conducting drying plates 10, to achieve head-to-tail connection.

[0045] The outer covers of the first transmission member 18, the second transmission member 19, the first heat-conducting hose 20, the second heat-conducting hose 22 and the return pipe 21 have a protective cover 4 fixed to the outer side of the drying box 1, and the protective cover 4 can protect the first transmission member 18, the second transmission member 19, the first heat-conducting hose 20, the second heat-conducting hose 22 and the return pipe 21.

[0046] The first transmission member 18 includes multiple groups of first sprockets, a first chain connecting the multiple groups of first sprockets and a guide shaft, the guide shaft is fixed on one side of the output shaft of the second motor 15, and the multiple groups of first sprockets are respectively installed on the ends of the multiple groups of mixing components 11 on the same side extending out of the drying box 1, the outside of the guide shaft and the output shaft of the second motor 15. As shown in the figure, when the first chain rotates, since the connection direction of the first chain and the two adjacent first sprockets is opposite, the two adjacent mixing components 11 are driven to rotate in the opposite direction, so that the mixing component 11 located in the drying box 1 can keep the sodium antimonate particles evenly transported to the center of the drying chamber 6. The second transmission member 19 includes two second sprockets and a second chain connecting the two second sprockets. The two second sprockets are respectively fixed on the ends of the two groups of mixing components 11 above the same material guiding drying plate 10, so that the two groups of mixing components 11 on the same material guiding drying plate 10 can rotate simultaneously.

[0047] The mixing assembly 11 includes a mixing roller 1101 rotatably mounted on the inner wall of the drying chamber 6 and a mixing brush plate 1102 mounted on the outside of the mixing roller 1101 . The first sprocket and the second sprocket are both fixed to the end of the mixing roller 1101 extending to the outside of the drying box 1 .

[0048] A plurality of air outlet nozzles 23 are fixedly provided on the inner wall of one end of the drying chamber 6 away from the lifting chamber 7. Each air outlet nozzle 23 is connected to the air outlet pipe 17, and a filter screen is provided at the air outlet of the air outlet nozzle 23 to prevent the sodium antimonate pyrophosphate particles from entering the air outlet nozzle 23 when being stirred.

[0049] During use: when drying the sodium antimonate pyrophosphate particles, first open the box cover 3, pour the sodium antimonate pyrophosphate particles into the drying box 1, and start the first motor 2 and the second motor 15. The sodium antimonate pyrophosphate particles first roll on the material guide drying plate 10, complete multiple groups of flips through multiple groups of material guide drying plates 10, and finally roll down to the material guide bottom slope 12, and finally enter the lifting chamber 7 from the bottom end of the material guide bottom slope 12 through the lifting feed port 9. In the lifting chamber 7, the first motor 2 drives the lifting shaft and the lifting auger 16 to rotate, and lifts the sodium antimonate pyrophosphate particles to the top of the drying box 1, and enters the material guide drying plate 10 again from the lifting discharge port 8 to roll, realizing cyclic rolling.

[0050] During the circulation and rolling process, the blast heating box 14 blows out hot air, and the hot air passes through the air outlet pipe 17 into the air outlet nozzle 23 and the inner cavity 24 of the material guiding bottom slope 12. The hot air passes through the first heat conducting hose 20 and the second heat conducting hose 22 in the inner cavity 24 and enters the material guiding drying plate 10 to heat the surface of the material guiding drying plate 10. At the same time, the hot air in the air outlet pipe 17 is discharged along the air outlet nozzle 23 to the drying chamber 6 to heat the sodium antimonate pyrophosphate particles, so that the sodium antimonate pyrophosphate particles on the material guiding drying plate 10 and the material guiding bottom slope 12 are heated both inside and outside. Heat drying is performed, and at this time the second motor 15 rotates, and the first transmission member 18 drives the mixing rollers 1101 and the mixing brush plates 1102 of the multiple groups of sheet material assemblies on the same side to rotate, and the mixing rollers 1101 and the mixing brush plates 1102 are opposite to the flow direction of the sodium antimonate pyrophosphate particles on the top of the material guiding drying plate 10, thereby facilitating the rotation and stirring of the sodium antimonate pyrophosphate particles, and coordinating the process of the sodium antimonate pyrophosphate particles rolling down from the material guiding drying plate 10 to another material guiding drying plate 10, the inner and outer parts of the sodium antimonate pyrophosphate particles are replaced back and forth multiple times.

[0051] After drying is completed, start the first motor 2 and the second motor 15 to reverse, and pull the pull-out baffle plate 5 out of the drying box 1. At this time, the first motor 2 drives the lifting shaft and the lifting auger 16 to reverse, and the sodium antimonate pyrophosphate particles are discharged from the bottom of the lifting chamber 7. At the same time, the second motor 15 drives the mixing roller 1101 and the mixing brush plate 1102 of the mixing component 11 to reverse, accelerating the rapid discharge of the sodium antimonate pyrophosphate particles on the material guide drying plate 10 and the material guide bottom slope 12, and finally the sodium antimonate pyrophosphate particles are discharged from the bottom end of the lifting chamber 7.

[0052] The device has high heating and drying efficiency for the sodium antimonate pyroate particles, good heating and drying effect, uniform and dispersed drying, and at the same time cooperates with the stirring process to ensure that the sodium antimonate pyroate particles can be fully spread and dried, and the processing is repeated in a cycle, which saves energy and reduces emissions, is stable and efficient, and is green and environmentally friendly.

[0053] Second embodiment

[0054] Reference Figure 7 and Figure 8 In the actual drying of the sodium antimonate pyrophosphate particles, due to the different drying degrees of the sodium antimonate pyrophosphate particles, the drying time and drying degree of the sodium antimonate pyrophosphate particles are different in the subsequent drying. However, the inclination angle of the material guiding drying plate 10 in the existing device is constant, so the speed at which the sodium antimonate pyrophosphate particles slide up and down on the material guiding drying plate 10 is constant, and the drying time and drying efficiency of the sodium antimonate pyrophosphate particles on the top of the material guiding drying plate 10 cannot be adjusted, which will increase the number of drying cycles, increase energy consumption, and reduce drying efficiency; and when the inclination angle of the material guiding drying plate 10 is adjusted, the distance between the material guiding drying plate 10 and the end of the mixing brush plate 1102 will change, so that the mixing brush plate 1102 cannot contact with the top of the material guiding drying plate 10, further reducing the stirring and drying effect of the sodium antimonate pyrophosphate particles on the top of the material guiding drying plate 10. In order to solve the above problems, the material guiding drying plate 10 is realized. The angle of the drying plate 10 can be adjusted to achieve the adjustment of the drying efficiency; and when the angle of the material guiding drying plate 10 changes, the distance between the mixing brush plate 1102 and the top of the material guiding drying plate 10 can be adaptively adjusted. The high-efficiency and environmentally friendly drying device for the production of sodium antimonate pyrophosphate particles also includes: a plurality of groups of fixed plates 26 are evenly arrayed in the middle of the inner walls on both sides of the drying chamber 6, and the fixed plates 26 are mainly located in the middle of the inner wall of the drying chamber 6 away from the rotating shaft end, and match the two side walls of the material guiding drying plate 10 away from the rotating shaft end. The other end of the fixed plate 26 is in sealing and sliding contact with the material guiding drying plate 10, thereby effectively improving the stability and sealing of the movement of the material guiding drying plate 10. Vertical blocks 25 are provided on both sides of the top of the material guiding drying plate 10. The setting of the vertical blocks 25 further improves the limiting and orderliness of the movement of the sodium antimonate pyrophosphate particles on the top of the material guiding drying plate 10, and avoids the loss of part of the sodium antimonate pyrophosphate particles by rolling to both sides to the top of the fixed plate 26.

[0055] A compression elastic tube 27 is provided at the bottom of the fixed plate 26, and a heat expansion gas is provided inside the compression elastic tube 27. Therefore, when the temperature of the drying chamber 6 or the top of the material guiding drying plate 10 rises, the heat expansion gas in the compression elastic tube 27 expands under the principle of thermal expansion and contraction, and the volume of the compression elastic tube 27 increases. A connecting plate 29 is provided at the bottom of the compression elastic tube 27. A return spring 28 is provided at the bottom of the fixed plate 26 and inside the compression elastic tube 27. The bottom of the other end of the return spring 28 is fixedly connected to the top of the connecting plate 29. When the temperature of the drying chamber 6 or the top of the material guiding drying plate 10 drops, the heat expansion gas in the compression elastic tube 27 expands. When the volume of the gas decreases, the elastic force of the return spring 28 drives the connecting plate 29 to move toward the end of the fixed plate 26. One end of the connecting plate 29 is fixedly connected to the bottom of the two side ends of the material guiding and drying plate 10 away from the inner wall of the drying chamber 6. Therefore, when the connecting plate 29 moves, it also drives the middle material guiding and drying plate 10 to move. Then, the inclination angle of the material guiding and drying plate 10 changes, and the discharge rate and drying rate of the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10 change. A distance sensor is provided on the top of the connecting plate 29. When the connecting plate 29 drives the middle material guiding and drying plate 10 to move, the distance value detected by the distance sensor changes synchronously.

[0056] The mixing assembly 11 located on the top of the material guiding drying plate 10 includes a mixing roller 1101. The peripheral side of the mixing roller 1101 is uniformly arranged with a plurality of inner grooves 1103. The inner bottom of the inner groove 1103 is provided with an electromagnet 1104. The magnetic magnitude of the electromagnet 1104 is changed by controlling the magnitude of the current flowing through the electromagnet 1104. A magnetic slider 1106 is slidably connected inside the inner groove 1103. The magnetism of the end faces facing each other of the electromagnet 1104 and the magnetic slider 1106 are different. A mixing brush plate 1102 is provided at the end of the slider 1106 away from the electromagnet 1104. When the magnetism of the electromagnet 1104 changes, the magnetic repulsion between the electromagnet 1104 and the magnetic slider 1106 changes, causing the sliding distance of the magnetic slider 1106 in the inner groove 1103 to change. The magnetic slider 1106 drives the mixing brush plate 1102 at the end to slide synchronously in the inner groove 1103, and the distance between the end of the mixing brush plate 1102 and the material guiding and drying plate 10 changes synchronously.

[0057] The electromagnet 1104 is provided with a connecting spring 1105 near the end of the magnetic slider 1106, and the other end of the connecting spring 1105 is fixedly connected to the side wall of the magnetic slider 1106. The other end of the mixing brush plate 1102 extends out of the inner groove 1103 and reaches the top of the material guiding and drying plate 10. Therefore, when the magnetic slider 1106 moves toward the end of the electromagnet 1104 in the inner groove 1103, the connecting spring 1105 will be stretched synchronously. Correspondingly, when the current flowing through the electromagnet 1104 decreases, the magnetic slider 1106 is driven to move away from the end of the electromagnet 1104 under the action of the elastic force of the connecting spring 1105.

[0058] When in use, it can be known from the first embodiment that the box cover 3 is opened and the sodium antimonate pyrophosphate particles are poured into the drying chamber 6 along the material opening, and at the same time, the controller controls the air blast heating box 14 to start and introduce hot air into the inner cavity 24 in the material guide bottom slope 12 through the air outlet pipe 17, and the hot air enters the inner cavity 24 inside the multiple groups of material guide drying plates 10 along the first heat-conducting hose 20 for transmission, and the hot air in the inner cavity 24 between the multiple groups of material guide drying plates 10 is transmitted through the first heat-conducting hose 20, and another part of the hot air in the air outlet pipe 17 is discharged into the drying chamber 6 along the air outlet nozzle 23 and heats and dries the surface of the sodium antimonate pyrophosphate particles on the top of the material guide drying plate 10, and at the same time The controller controls the first motor 2 to start, and the first motor 2 drives the lifting auger 16 to rotate forward in the lifting chamber 7, so that the sodium antimonate pyrophosphate particles in the lifting chamber 7 are transferred from the bottom to the top, and finally are re-discharged into the drying chamber 6 along the lifting outlet 8 for drying. The controller controls the second motor 15 to start, and rotates through the first transmission member 18 and the second transmission member 19. When the first transmission member 18 and the second transmission member 19 rotate, the mixing component 11 is driven to rotate, and the sodium antimonate pyrophosphate particles on the top of the material guiding drying plate 10 are rotated and stirred with the help of the mixing brush plate 1102, so as to further improve the drying efficiency of the sodium antimonate pyrophosphate particles on the top of the material guiding drying plate 10.

[0059] When the sodium antimonate pyrophosphate particles on the top of the material-guiding drying plate 10 are dried, the hot air flowing in the inner cavity 24 of the material-guiding drying plate 10 and the hot air discharged along the air outlet 23 are mainly used to dry the sodium antimonate pyrophosphate particles. Since the temperature of the sodium antimonate pyrophosphate particles on the top of the material-guiding drying plate 10 is relatively low, the heat exchange efficiency of the sodium antimonate pyrophosphate particles is high. The hot air in the inner cavity 24 and the hot air in the drying cavity 6 have a strong cooling effect on the sodium antimonate pyrophosphate particles after drying. The temperature around the corresponding material-guiding drying plate 10 is reduced, and the hot expansion gas in the compressed elastic tube 27 is compressed due to the heat. The principle of expansion and contraction causes its volume to decrease, and the connecting plate 29 is driven to move upward under the elastic force of the compressed elastic tube 27 and the internal return spring 28. When the connecting plate 29 moves upward, it drives one end of the middle material guiding and drying plate 10 to move upward, so that the inclination angle of the material guiding and drying plate 10 is reduced, and the rate at which the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10 slide downward under the action of their own weight is reduced, thereby improving the drying time and drying efficiency of the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10, ensuring that the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10 can be thoroughly and effectively heated and dried.

[0060] When the connecting plate 29 moves upward, the distance value detected by the distance sensor decreases, and the controller controls the second motor 15 to increase its rotation speed. The second motor 15 drives the mixing component 11 to increase its rotation speed through the first transmission member 18 and the second transmission member 19. Specifically, the rotation direction of the mixing component 11 is opposite to the flow direction of the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10. Therefore, when the mixing component 11 rotates, it will increase the reverse stirring and flow resistance of the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10, which can not only further reduce the flow speed of the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10, thereby increasing the heating and drying time of the sodium antimonate particles, but also stir and turn over the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10, thereby improving the drying uniformity and thoroughness of the sodium antimonate particles, and avoiding incomplete drying at some positions, which reduces the product quality of the sodium antimonate particles.

[0061] At the same time, when the distance value detected by the distance sensor decreases and the rotation speed of the mixing component 11 increases, the controller controls the current of the electromagnet 1104 inside the mixing component 11 to increase, and the magnetic attraction of the electromagnet 1104 on the magnetic slider 1106 drives the magnetic slider 1106 to squeeze the connecting spring 1105 and move toward the end close to the electromagnet 1104. When the magnetic slider 1106 moves, it simultaneously drives the mixing brush plate 1102 at the end to move along the inner groove 1103 toward the end close to the electromagnet 1104, and the distance that the mixing brush plate 1102 extends out of the inner groove 1103 is reduced, thereby ensuring that the end of the mixing brush plate 1102 is in contact with the top of the material guiding and drying plate 10 at all times, avoiding the mixing brush plate 1102 from colliding with the top of the material guiding and drying plate 10 when the mixing brush plate 1102 extends out too long, thereby reducing the stirring and drying effect of the mixing brush plate 1102 on the sodium antimonate particles on the top of the material guiding and drying plate 10.

[0062] At the same time, as the rotation speed of the mixing component 11 increases, the stirring and flow-blocking effect of the mixing component 11 on the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10 is increased, thereby further improving the drying time and drying efficiency of the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10, ensuring that the sodium antimonate pyrophosphate particles can be fully and thoroughly heated and dried inside the drying chamber 6.

[0063] When the sodium antimonate pyrophosphate particles on the top of the material guiding drying plate 10 continuously flow in sequence and finally fall to the top of the material guiding bottom slope 12, at the same time, they enter the bottom of the lifting chamber 7 along the lifting feed port 9 along the top of the material guiding bottom slope 12, and under the rotation of the lifting auger 16 inside the lifting chamber 7, the sodium antimonate pyrophosphate particles are transported back to the top of the lifting chamber 7 and discharged along the lifting discharge port 8.

[0064] The temperature of the sodium antimonate pyroxene particles that are re-discharged into the drying chamber 6 along the lifting outlet 8 has increased. Therefore, when flowing on the top of the material guiding drying plate 10, the heat exchange efficiency between the hot air in the inner cavity 24 and the hot air discharged from the air outlet 23 and the sodium antimonate pyroxene particles decreases, and the temperature around the material guiding drying plate 10 continues to rise, and the volume of the compressed elastic tube 27 increases. The compressed elastic tube 27 drives the bottom connecting plate 29 to stretch the reset spring 28 and move downward. When the connecting plate 29 moves downward, it simultaneously drives the material guiding drying plate 10 to move downward away from the inner wall end of the drying chamber 6, the downward tilt angle of the material guiding drying plate 10 increases, and the distance value detected by the distance sensor increases.

[0065] The corresponding controller controls the second motor 15 to decrease its rotation speed, and the second motor 15 drives the mixing component 11 to decrease its rotation speed through the first transmission member 18 and the second transmission member 19. At the same time, the controller controls the current of the electromagnet 1104 in the inner groove 1103 to decrease, and drives the magnetic slider 1106 to move away from the end of the electromagnet 1104 under the elastic force of the connecting spring 1105. The magnetic slider 1106 simultaneously drives the mixing brush plate 1102 at the end to move away from the end of the electromagnet 1104, and the distance that the mixing brush plate 1102 extends out of the inner groove 1103 increases. The end of the mixing brush plate 1102 can still ensure contact with the top of the material guiding and drying plate 10, and cooperates with the rotation of the mixing roller 1101 to achieve the stirring and drying effect of the mixing brush plate 1102 on the sodium antimonate pyrophosphate particles on the top of the material guiding and drying plate 10.

[0066] As the heating and drying of the sodium antimonate pyrophosphate particles inside the drying chamber 6 is continuously carried out, and the sodium antimonate pyrophosphate particles inside the lifting chamber 7 are continuously circulated and discharged, the temperature of the sodium antimonate pyrophosphate particles continues to rise and reaches the set drying temperature. Then, when inside the drying chamber 6, the heat exchange efficiency with the hot air in the inner cavity 24 and the hot air discharged into the drying chamber 6 from the air outlet nozzle 23 continues to decrease, the temperature around the material guiding drying plate 10 continues to rise, the volume of the compressed elastic tube 27 continues to increase, and the distance value detected by the distance sensor continues to increase. When the distance values ​​detected by the distance sensor are all greater than the preset distance values, it means that the sodium antimonate pyrophosphate particles in the drying chamber 6 have been heated and dried. Then, it is only necessary to open the pull-out baffle plate 5 and control the first motor 2 to rotate in the opposite direction. The first motor 2 drives the lifting auger 16 to rotate in the opposite direction, and cooperates with the material guiding bottom slope 12 to discharge the sodium antimonate pyrophosphate particles along the bottom of the lifting chamber 7 to complete the heating and drying of the sodium antimonate pyrophosphate particles.

[0067] The device has high heating and drying efficiency and good heating and drying effect. At the same time, it can also adaptively adjust the inclination degree of the material guiding and drying plate 10 according to the heating and drying degree of the sodium antimonate pyroxene particles, thereby adjusting the heating time and drying degree of the sodium antimonate pyroxene particles. It has higher stability and better adaptability. It can also adaptively adjust the rotation speed of the mixing component 11 and the extension length of the mixing brush plate 1102 according to the inclination angle of the material guiding and drying plate 10, further ensuring that the mixing brush plate 1102 and the top of the material guiding and drying plate 10 are in contact with each other for stirring, resulting in better stirring effect, more uniform and thorough stirring, simple operation, energy saving and emission reduction, and green environmental protection.
