[0016] (III) Beneficial effects Compared with the prior art, the present invention provides a dehydration device for beta gypsum production, which has the following beneficial effects: 1. The dehydration device for β-gypsum production adopts the hydraulic rod, support plate, slide plate, slide frame, rack and other components of the adjustment part to cooperate with the main shaft and gear ring, which can change the processing angle of the reactor, thereby realizing the conversion between the dehydration mode and the cleaning mode. This design makes it easy to switch to the cleaning mode and clean the reactor during the production process without complicated manual operation, thereby improving the use efficiency and convenience of the equipment.

[0017] 2. The dehydration device used for β-gypsum production adopts flexible conversion between dehydration mode and discharging mode. Through the unique design of the conversion part, including the frame, support arm, main shaft, gear ring and other components, the reactor can be installed flexibly at a high position, so that the dehydration mode and discharging mode can be flexibly switched under different work requirements. During the dehydration process, the reactor can be in a suitable position and angle for heating and dehydration operations. When the dehydration is completed, it can be easily converted to the discharging mode to discharge the β-gypsum.

[0018] 3. The dehydration device for β-gypsum production adopts a transmission structure composed of a motor, a rotating shaft, a turntable, a rocker arm, a mounting arm and other components of the frying part, which can drive the reactor to produce a reciprocating swinging motion. During the swinging process of the reactor, the dihydrate gypsum inside is in full contact with the heated frying plate, and the crystal water is removed by direct heating to be converted into β-type hemihydrate gypsum. This frying method can make the gypsum heated more evenly and improve the dehydration efficiency and quality. The dehydration part not only has the function of frying and dehydration, but also can be cleaned by injecting water through the water injection pipe, and the prepared β-gypsum can be discharged through the discharge pipe. This diversified design allows the device to flexibly select different dehydration methods according to actual production needs and process requirements, such as frying first and then cleaning, or directly heating and dehydrating before discharging, etc., thereby improving the adaptability and practicality of the device.

[0019] 4. The dehydration device for β-gypsum production adopts the connecting block, reciprocating screw, screw slider, descaling ring and other components of the cleaning part to form an automated cleaning system. When the reactor is switched to the cleaning mode, the motor of the discharge part, the docking card seat and other components can cooperate to drive the reciprocating screw to rotate, drive the screw slider and the descaling ring to reciprocate on the inner wall of the reactor, and scrape off the residual dirt on the inner wall. This automated cleaning method greatly reduces the pressure of manual cleaning and improves the cleaning efficiency. During the cleaning process, the inner wall of the reactor can be flushed by opening the electric valve of the water injection pipe. The cover plate can slide between the slides to close the pressure relief hole to prevent the gypsum crystals from rolling out and wasting. At the same time, it can also play a role in preventing water leakage, so that the water flow can more effectively cover the area passed by the gypsum crystals, flush away the residual dirt, and avoid scaling in the reactor to cause pollution and corrosion.

[0020] 5. The dehydration device used for β-gypsum production adopts a stir-frying plate that can be detachably installed in the through hole at the bottom of the reactor, which is convenient for loading and unloading and cleaning during regular major maintenance. Electric valves are installed on the discharge pipe and the water injection pipe to facilitate the control of the inflow and outflow of materials and the on and off of water flow. The design of the support beam and the base provides stable support for the entire device, ensuring the stability of the device during operation. The various components of the device are reasonably designed and closely cooperate with each other.

[0021] 6. The dehydration device for β-gypsum production adopts a control panel installed on one of the supporting beams. The control panel can conveniently control the operation of components such as motors, heating plates, hydraulic rods, and electric valves to achieve automatic control of the entire device. This design improves the convenience of operation and reduces the safety risks that may be caused by manual operation. During the flipping and discharging process of the reactor, the control panel can be used to accurately control the actions of each component to avoid equipment damage or safety accidents caused by improper manual operation.

[0029] In order to reduce the pressure of manual cleaning after using the reactor 41, the cleaning part 5 of this case includes two connecting blocks 51, and the two connecting blocks 51 are respectively fixedly connected to the top of the two ends of the reactor 41, and a reciprocating screw 52 is rotatably connected between the two connecting blocks 51.

A control panel 10 is installed on one of the supporting beams 6, and the process of this case can be conveniently controlled through the control panel 10.

[0030] It is worth noting that in order to switch the working mode of the reactor 41 more freely, the adjustment part 8 in this case includes two rod sleeves 81, the two rod sleeves 81 are fixedly installed on one side of the top of the base 7, and the inner walls of the two rod sleeves 81 are installed with hydraulic rods 82, and the inner rod ends of the two hydraulic rods 82 are fixedly connected with support plates 83, and the bottom side of the frame 1 is in contact with the top of the support plate 83, which can limit the excessive rotation of the frame 1 and maintain working balance, and the bottom of the support plate 83 is fixedly connected with a slide plate 84, and the tops of both sides of the support plate 83 are fixedly connected with slide frames 85, and the two slide frames 85 are fixedly connected with racks 86 on the sides away from each other, and the slide plate 84 is in contact with the base 7, and the outer rod ends of the two hydraulic rods 82 extend to the top of the slide plate 84, and the two ends of the main shaft 26 slide through the inner walls of the two slide frames 85 respectively, and the two gear rings 27 are respectively meshed with the two racks 86, and the racks 86 are driven to move by the sliding of the slide frame 85, so that the gear ring 27 drives the main shaft 26 to rotate and change the angle.

[0031] It is worth noting that in order to further promote the automatic cleaning work after the reaction kettle 41 mode is switched, the discharge part 9 of this case includes a second motor 91, which is fixedly installed on the top of the slide 84, and the output shaft of the second motor 91 is fixedly connected to the second shaft 92, and the end of the second shaft 92 is fixedly connected to the docking card seat 93, and the docking card seat 93 is provided with a card slot corresponding to the docking block 55, and the card slot can be directly inserted into the limit position after the docking block 55 is turned over.

The discharge part 9 also includes a bottom block 94, and the bottom block 94 is fixedly connected to the top of the slide plate 84 and aligned with the motor 2 91. Both sides of the bottom block 94 are hinged with hinged plates 95, and the bottom block 94 and the hinged plates 95 have a certain hinge tightness. The tops of the two hinged plates 95 are fixedly connected with a discharge channel 96, and the discharge channel 96 can be flipped and fixed in position with the hinged part of the hinged plate 95 as the axis.

[0032] Working principle: In this case, the control panel 10 is electrically connected to the motor 1 31, the heating plate 47, the motor 2 91, the hydraulic rod 82, and the electric valve, and the encoders of the relevant configuration are preset for program, which is convenient for adapting to the processing needs in different situations. The dihydrate gypsum is added into the reactor 41 by opening the cover on the feeding port 43. After starting the motor 1 31, the rotating disk 33 is driven to rotate through the rotating shaft 1 32, so that the rocker arm 35 performs a curved motion, and at the same time drives the sliding pin 42 on the reactor 41 to slide back and forth in the positioning frame 24, so as to achieve the reciprocating swing effect of the reactor 41. When the reactor 41 is swinging, the dihydrate gypsum contacts the heated stir-frying plate 46 in the reactor for stir-frying. The crystal water in the dihydrate gypsum is removed by direct heating and converted into β-type hemihydrate gypsum. During the frying process, the heat is transferred to the inside of the gypsum crystal, destroying the chemical bonds of the crystal water in the crystal structure, so that the crystal water escapes from the pressure relief hole 48 in the form of water vapor.

[0033] After the frying is completed, the rocker arm 35 on the turntable 33 is driven by the motor 31 to rotate and position to the horizontal position, so that the reactor 41 is kept in a horizontal state and the motor 31 is locked by the brake. At this time, the control panel 10 is used to control the inner rod of the hydraulic rod 82 to contract, and the slide plate 84 is driven to slide through the support plate 83. The slide plate 84 is limited between the hydraulic rod 82 and the base 7 and the two support beams 6 to avoid the risk of shaking and deviation. The support plate 83 drives the two slide frames 85 to slide horizontally and drives the gear ring 27 to rotate through the rack 86, so that the main shaft 26 drives the conversion part 2 and the stir-frying part 3 and the dehydration part 4 on the frame plate 1 to flip synchronously to a vertical state. The β gypsum is concentrated at the bottom of the inner wall of the reactor 41 at this time, and the cover plate 57 is pushed to slide between the slideways 56, so that the cover plate 57 is blocked and covered between the screw slider 53 and the connecting block 51 to cover the pressure relief hole 48, so as to avoid the waste of gypsum crystals rolling out.

[0034] After the reciprocating screw 52 is perpendicular to the base 7, the docking block 55 and the extended end of the reciprocating screw 52 are both inserted into the docking card seat 93 to be fixed, and the discharge pipe 44 is aligned above the discharge channel 96. One side of the discharge channel 96 is pressed down to an inclined state, and a recovery tool is placed at a low position. The electric valves of the discharge pipe 44 and the water injection pipe 45 are opened through the control panel 10, and the β gypsum is discharged from the discharge pipe 44 into the discharge channel 96 and rolls into the recovery tool to complete the discharge. After the β gypsum is discharged, the other end of the discharge channel 96 is pressed down to an inversely inclined state, and a wastewater recovery tool is set at its low position. At this time, the cover plate 57 is slid away from the pressure relief hole 48, and the motor 2 91 works to cause the rotating shaft 2 92 to drive the docking card seat 93 to rotate, so that the reciprocating screw 52 rotates to drive the screw slider 53 to reciprocate on the inner wall of the pressure relief hole 48, thereby scraping off the dirt on the inner wall of the pressure relief hole 48 through the screw slider 53, and at the same time, the descaling ring 54 scrapes The dirt on the inner wall of the reactor 41 is removed, and then the screw slider 53 is reset to the top of the reciprocating screw 52, ​​and the cover plate 57 is slid again to close the pressure relief hole 48. The water pipe can be inserted into the water injection pipe 45 to directly rinse the inner wall of the reactor 41. The water should be mixed with a suitable acidic cleaning agent or alkaline cleaning agent or surfactant according to the actual material of the reactor 41 to ensure that the adhesion of dirt is reduced while reducing the corrosion to the reactor 41. The cover plate 57 closes the pressure relief hole 48 and can also play a role in preventing water leakage, so that the water flow can rinse the inner wall of the reactor 41 as much as possible, and discharge the dirt inside the reactor from the discharge pipe 44 into the discharge channel 96 and guide it to the wastewater recovery tool for discharge. During the cleaning process, the water flow can effectively cover the area passed by the gypsum crystals, wash away the dirt, and avoid scaling in the reactor 41 to cause pollution and corrosion, eliminating the pressure and difficulty of real-time human cleaning, and improving the cleaning efficiency and convenience.
