Description

Technical Field

[0001] This invention relates to the field of magnesium sulfate drying technology, specifically to an automatic drying device for purifying magnesium sulfate raw materials and its usage method. Background Technology

[0002] Magnesium sulfate has a wide range of applications in food, medicine and other fields. Currently, there is no unified standard for high-purity magnesium sulfate. As an important inorganic salt, its technical background covers resource distribution, production methods, multi-field applications and technological development trends.

[0003] Existing drying equipment for magnesium sulfate purification makes it easy for magnesium sulfate to come into contact with external water vapor during collection after drying. This causes the dried magnesium sulfate crystals to become damp again, affecting the quality of the produced magnesium sulfate. In severe cases, secondary drying is required, which affects the storage and use of magnesium sulfate. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic drying device for purifying magnesium sulfate raw materials and its method of use. To achieve the above objectives, the present invention provides the following technical solution: an automatic drying device for purifying magnesium sulfate raw materials, comprising a first protective sleeve, a second protective sleeve disposed inside the first protective sleeve, a water absorption mechanism for adsorbing and discharging water vapor disposed at the upper end of the second protective sleeve, and a drying mechanism for driving the material and promoting drying disposed on one side of the second protective sleeve. The water absorption mechanism includes a filter disc disposed on the upper end of the second protective sleeve. Inside the filter disc is a water-absorbing block that can absorb water and increase its weight. The upper end of the water-absorbing block is connected to a first air outlet pipe. A blocker plate that can move up and down is disposed on one side of the first air outlet pipe. A squeezing sleeve is connected to one side of the blocker plate through an air guide pipe. A squeezing plate that can squeeze and dehydrate the water-absorbing block is disposed at the bottom of the squeezing sleeve. A first spring sleeve that controls the resetting of the blocker plate is disposed at the lower end of the blocker plate. A second spring sleeve is also disposed on the filter disc. A second connecting rod that can trigger the opening of the discharge gate is connected to one end of the second spring sleeve. The drying mechanism includes an electric telescopic rod fixedly installed at the bottom of the second protective sleeve. The output end of the electric telescopic rod is provided with a drying plate for bearing and vibrating the material. A piston is connected to the drying plate through a third connecting rod. An exhaust head is correspondingly provided at the upper end of the piston. A rack is also connected to the bottom of the drying plate. The rack meshes with a ratchet, and the ratchet drives a fan to rotate.

[0005] Preferably, the filter disc is provided with a fixing disc inside, the interior of the fixing disc is fixed to the water absorption block, a second air outlet pipe is provided at one end of the first air outlet pipe, the blocking plate is connected to the second air outlet pipe through the blocking plate, a first hole is provided on the blocking plate, an air guide pipe is provided on one side of the second air outlet pipe, one end of the air guide pipe passes through the first air outlet pipe and connects to the compression sleeve, and a one-way valve is provided inside the second air outlet pipe.

[0006] Preferably, a return spring is provided inside the extrusion sleeve. One end of the return spring is connected to the inner wall of the first protective sleeve, and the lower end of the return spring is connected to the extrusion plate. The size of the extrusion plate is adapted to the water-absorbing block.

[0007] Preferably, a water outlet pipe is provided on one side of the filter disc, a water tank is provided on one side of the water outlet pipe, and a water pump is also provided on the water outlet pipe.

[0008] Preferably, the lower end of the filter disc is connected to the exhaust pipe, the lower end of the exhaust pipe is connected to the exhaust head, and the size of the exhaust head is adapted to the piston.

[0009] Preferably, a third connecting rod is provided on both sides of the drying plate, the upper end of the third connecting rod is connected to the piston, a connecting plate is provided at the bottom of the drying plate, one end of the connecting plate is connected to the rack, a connecting disc is provided inside the second protective sleeve, the connecting disc is connected to the ratchet, and telescopic columns are also provided on both sides of the drying plate, with buffer springs provided inside the telescopic columns.

[0010] Preferably, a notch is provided on one side of the second protective sleeve, and a rotating shaft plate is provided on one side of the notch. The bottom of the rotating shaft plate is connected to the rotating door, and one side of the rotating door is in contact with the limiting block. A discharge rail groove is provided inside the notch.

[0011] Preferably, the second spring sleeve is provided with a first connecting rod, one end of the first connecting rod is connected to the second connecting rod, the second connecting rod is provided with a first magnet, and one end of the second connecting rod is also provided with a second magnet, and the first protective sleeve is provided with a feeding port.

[0012] An automatic drying method for purifying magnesium sulfate raw materials includes the following steps: Step 1: Add the purified and crystallized magnesium sulfate crystals into the device through the feed port. Pre-crush the magnesium sulfate crystals to prevent them from clumping. After crushing, add them to the drying plate for drying. Step 2: After adding the magnesium sulfate to the drying plate, start the electric telescopic rod. The electric telescopic rod drives the drying plate to reciprocate, which in turn drives the magnesium sulfate crystals on the water absorption mechanism to dry the magnesium sulfate on the drying plate evenly. Step 3: The reciprocating motion of the electric telescopic rod drives the piston to move, and the water vapor inside the second protective sleeve is absorbed by the water absorption block inside the filter plate. After absorption, the water absorption block becomes heavier and squeezes the first spring sleeve and the second spring sleeve, which drives the block plate and the second connecting rod to move. Step 5: When the blocking plate descends to a certain height, the second air outlet pipe connects with the air guide pipe, driving the squeezing plate to squeeze the first air outlet pipe, so that the water in the water absorption block flows out into the water tank through the water pump. At the same time, the second spring sleeve descends and drives the second connecting rod to control the opening and closing of the rotating door, which facilitates the collection of dried magnesium sulfate on the drying plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the linkage of the second spring sleeve and the second connecting rod, triggers the rotating door to open only when the water-absorbing block reaches a predetermined saturation level, i.e., when the material is basically dry. This ensures that material is discharged only after drying is complete, effectively preventing external moisture from intruding or semi-finished products from being discharged prematurely during the drying process, thus guaranteeing product quality and operational safety.

[0014] This invention drives the drying plate to reciprocate through an electric telescopic rod. On the one hand, it vibrates the material to ensure even heating and prevent clumping. On the other hand, the engagement of the rack and ratchet converts linear motion into unidirectional rotation of the fan, achieving forced circulation of air in the drying chamber without the need for an additional motor. The structure is ingenious and energy-efficient.

[0015] This invention uses the increase in weight of the absorbent block as a control signal. When the absorbent block becomes saturated with water and increases in weight, it will trigger the action of the first spring sleeve and the second spring sleeve in sequence. The action of the first spring sleeve will eventually cause the squeezing plate to squeeze and dehydrate the absorbent block, thus regenerating it. This realizes the automatic cleaning and recycling of the dehumidification unit without manual intervention, ensuring continuous drying efficiency. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] The present invention provides an automatic drying device for purifying magnesium sulfate raw materials, including a first protective sleeve 1, a second protective sleeve 13 disposed inside the first protective sleeve 1, a water absorption mechanism 2 disposed at the upper end of the second protective sleeve 13 for adsorbing and discharging water vapor, and a drying mechanism 3 disposed on one side of the second protective sleeve 13 for driving the material and promoting drying. The water absorption mechanism 2 includes a filter disc 21 set on the upper end of the second protective sleeve 13. The filter disc 21 is equipped with a water absorption block 22 that can absorb water and increase weight. The upper end of the water absorption block 22 is connected to a first air outlet pipe 214. A block plate 232 that can move up and down is set on one side of the first air outlet pipe 214. A squeezing sleeve 235 is connected to one side of the block plate 232 through an air guide pipe 234. A squeezing plate 237 that can squeeze and dehydrate the water absorption block 22 is set at the bottom of the squeezing sleeve 235. A first spring sleeve 23 that controls its reset is set at the lower end of the block plate 232. A second spring sleeve 24 is also set on the filter disc 21. A second connecting rod 242 that can trigger the opening of the discharge gate is connected to one end of the second spring sleeve 24. The drying mechanism 3 includes an electric telescopic rod 31 fixedly installed at the bottom of the second protective sleeve 13. The output end of the electric telescopic rod 31 is provided with a drying plate 32 for bearing and vibrating the material. A piston 34 is connected to the drying plate 32 through a third connecting rod 33. An exhaust head 25 is correspondingly provided at the upper end of the piston 34. A rack 322 is also connected to the bottom of the drying plate 32. The rack 322 meshes with a ratchet 323, and the ratchet 323 drives a fan 324 to rotate.

[0020] Before using this device, the mass of water molecules released is calculated based on the mass of the purified magnesium sulfate heptahydrate added. The springs inside the first spring sleeve 23 and the second spring sleeve 24 are then adjusted accordingly. The purified magnesium sulfate crystals are then added to the device through the feeding port 11. The electric telescopic rod 31 extends and retracts, causing the drying plate 32 to reciprocate, which in turn moves the magnesium sulfate crystals on the drying plate 32 to dry them thoroughly. At the same time, the reciprocating motion of the drying plate 32 causes the connecting plate 321 to reciprocate, which in turn causes the rack 322 to reciprocate. When the rack 322 rises, it causes the ratchet 323 to rotate, which in turn causes the fan 324 to rotate, allowing the hot air inside the second protective sleeve 13 to circulate. This auxiliary device ensures thorough drying and prevents some crystals from being squeezed by other crystals during drying, which could result in incomplete drying and affect the quality of the magnesium sulfate crystals.

[0021] Simultaneously, the reciprocating motion of the drying plate 32 drives the piston 34 to reciprocate, drawing the gas from the second protective sleeve 13 into the water-absorbing block 22 through the telescopic column 35 to absorb water. The moisture generated after the magnesium sulfate crystals are dried is collected. At the same time, the gas that has lost moisture enters the second air outlet pipe 233 through the first air outlet pipe 214. As the weight of the water collected in the water-absorbing block 22 increases, the water-absorbing block 22 descends, causing the fixed plate 213 to descend as well. This causes the first spring sleeve 23 at the bottom of the fixed plate 213 to be squeezed. The first spring sleeve 23 contracts, causing the blocking plate 232 to move. When the blocking plate 232 moves to the first hole and contacts the second air outlet pipe 233, the gas in the second air outlet pipe 233 enters the air guide pipe 234 through the blocking plate 232. By squeezing the squeezing plate 237, the squeezing plate 237 removes the moisture from the water-absorbing block 22, causing the blocking plate 232 to reset and begin the next drying cycle.

[0022] Simultaneously, the fixed plate 213 descends, causing the second spring sleeve 24 to contract. The second spring sleeve 24 descends, causing the first connecting rod 241 to descend. The first connecting rod 241 descends, causing the second connecting rod 242 to descend. When the second connecting rod 242 descends, the second magnet 244 on the second connecting rod 242 attracts the limiting block 245, causing the limiting block 245 to flip, so that the rotating door 26 is not restricted by the limiting block 245. At the same time, when the second connecting rod 242 descends to a certain extent, the first magnet 243 attracts the rotating door 26, causing the rotating door 26 to flip, opening the second protective sleeve 13. This makes it convenient for workers to collect the dry magnesium sulfate inside the second protective sleeve 13. At the same time, due to the reciprocating motion of the piston 34, most of the moisture in the second protective sleeve 13 is removed, preventing the magnesium sulfate inside the second protective sleeve 13 from coming into contact with moisture when the rotating door 26 flips, which would cause dampness and affect the drying effect.

[0023] In an optional embodiment, a fixing plate 213 is provided inside the filter disc 21, and the interior of the fixing plate 213 is fixed to the water absorption block 22. A second air outlet pipe 233 is provided at one end of the first air outlet pipe 214. A blocking plate 232 is connected to the second air outlet pipe 233 through the second air outlet pipe 233. A first hole is provided on the blocking plate 232. An air guide pipe 234 is provided on one side of the second air outlet pipe 233. One end of the air guide pipe 234 passes through the first air outlet pipe 214 and connects to the compression sleeve 235. A one-way valve is provided inside the second air outlet pipe 233.

[0024] It should be noted that the movement of the water-absorbing block 22 causes the fixed plate 213 to move, thereby squeezing the first spring sleeve 23 and the second spring sleeve 24. At the same time, the gas that has absorbed water enters the second air outlet 233 through the first air outlet 214. The gas in the second air outlet 233 is blocked by the blocking plate 232, resulting in a slightly higher air pressure inside the second air outlet 233. At the same time, since a one-way valve is installed inside the second air outlet 233, the gas in the first air outlet 214 continues to fill the second air outlet 233, increasing the air pressure inside the second air outlet 233.

[0025] In an optional embodiment, a return spring 236 is provided inside the extrusion sleeve 235. One end of the return spring 236 is connected to the inner wall of the first protective sleeve 1, and the lower end of the return spring 236 is connected to the extrusion plate 237. The size of the extrusion plate 237 is adapted to the water absorption block 22.

[0026] It should be noted that when a certain amount of water is collected in the water-absorbing block 22, the water-absorbing block 22 descends, causing the fixed plate 213 to descend, which in turn squeezes the first spring sleeve 23, causing the first spring sleeve 23 to contract and causing the blocking plate 232 to descend. After the blocking plate 232 descends to the point where the first hole on the blocking plate 232 connects with the second air outlet pipe 233, gas is injected from the second air outlet pipe 233 into the squeezing sleeve 235, which squeezes the squeezing plate 237. The squeezing plate 237 squeezes the water in the water-absorbing block 22 into the filter plate 21 for easy use next time, while simultaneously causing the first spring sleeve 23 to reset.

[0027] In an optional embodiment, a water outlet pipe 211 is provided on one side of the filter disc 21, a water tank 12 is provided on one side of the water outlet pipe 211, and a water pump 212 is also provided on the water outlet pipe 211.

[0028] It should be noted that the water squeezed by the extrusion plate 237 is inside the filter plate 21, and the water in the filter plate 21 is transported to the water tank 12 through the water outlet pipe 211 by the water pump 212.

[0029] In an optional embodiment, the lower end of the filter disc 21 is connected to the exhaust pipe 251, the lower end of the exhaust pipe 251 is connected to the exhaust head 25, and the size of the exhaust head 25 is adapted to the piston 34.

[0030] It should be noted that the piston 34 reciprocates, introducing the gas containing moisture into the exhaust pipe 251 through the exhaust head 25, and then into the filter plate 21 through the exhaust pipe 251.

[0031] In an optional embodiment, a third connecting rod 33 is provided on both sides of the drying plate 32. The upper end of the third connecting rod 33 is connected to the piston 34. A connecting plate 321 is provided at the bottom of the drying plate 32. One end of the connecting plate 321 is connected to the rack 322. A connecting disc 325 is provided inside the second protective sleeve 13. The inside of the connecting disc 325 is connected to the ratchet 323. Telescopic columns 35 are also provided on both sides of the drying plate 32. A buffer spring 351 is provided inside the telescopic column 35.

[0032] It should be noted that the movement of the drying plate 32 drives the third connecting rod 33 to move, which in turn drives the piston 34 to move. At the same time, the movement of the drying plate 32 drives the rack 322 to move. When it rises, it drives the ratchet 323 to rotate, increasing the airflow inside the second protective sleeve 13. When it falls, the rack 322 does not rotate with the ratchet 323, so it does not affect the internal environment of the second protective sleeve 13. At the same time, the movement of the drying plate 32 adjusts the telescopic column 35 to extend and retract, which drives the buffer spring 351 to extend and retract, reducing the impact of the movement of the drying plate 32 on the device.

[0033] In an optional embodiment, a notch is provided on one side of the second protective sleeve 13, and a rotating shaft plate 261 is provided on one side of the notch. The bottom of the rotating shaft plate 261 is connected to the rotating door 26, and one side of the rotating door 26 is in contact with the limiting block 245. A discharge rail groove 262 is provided inside the notch.

[0034] It should be noted that when the water-absorbing block 22 absorbs a certain amount of water, it causes the second spring sleeve 24 to move a certain distance. Then, the second magnet 244 causes the limiting block 245 to flip, and the first magnet 243 causes the rotating door 26 to flip, exposing the notch so that the magnesium sulfate on the drying plate 32 can be collected from the discharge rail 262.

[0035] In an optional embodiment, a first connecting rod 241 is provided on the second spring sleeve 24, one end of the first connecting rod 241 is connected to the second connecting rod 242, a first magnet 243 is provided on the second connecting rod 242, a second magnet 244 is also provided on one end of the second connecting rod 242, and a feeding port 11 is provided on the first protective sleeve 1.

[0036] It should be noted that the movement of the second spring sleeve 24 first drives the movement of the second magnet 244. After the second magnet 244 moves to the designated position, it drives the limit block 245 to rotate. After rotation, the limit block 245 does not squeeze the revolving door 26. After working for a period of time, the water-absorbing block 22 collects a certain amount of water and drives the second spring sleeve 24 to compress a certain distance, which drives the first magnet 243 to move to the designated position, attracting the revolving door 26 and causing the revolving door 26 to flip.

[0037] An automatic drying method for purifying magnesium sulfate raw materials includes the following steps: Step 1: Add the purified and crystallized magnesium sulfate crystals into the device through the feed port 11. Pre-crush the magnesium sulfate crystals to prevent them from clumping. After crushing, add them to the drying plate 32 for drying. Step 2: After adding to the drying plate 32, start the electric telescopic rod 31. The electric telescopic rod 31 drives the drying plate 32 to reciprocate, which drives the magnesium sulfate crystals on the water absorption mechanism 2 to dry, and evenly dries the magnesium sulfate on the drying plate 32. Step 3: The reciprocating motion of the electric telescopic rod 31 drives the piston 34 to move, and the water vapor inside the second protective sleeve 13 is absorbed by the water absorption block 22 inside the filter plate 21. After absorption, the water absorption block 22 becomes heavier and squeezes the first spring sleeve 23 and the second spring sleeve 24, which drives the block plate 232 and the second connecting rod 242 to move. Step 5: When the blocking plate 232 descends to a certain height, the second vent pipe 233 connects with the air guide pipe 234, driving the squeezing plate 237 to squeeze the first vent pipe 214, so that the water in the water absorption block 22 flows out into the water tank 12 through the water pump 212. At the same time, the second spring sleeve 24 descends and drives the second connecting rod 242 to control the opening and closing of the rotating door 26, so as to facilitate the collection of dried magnesium sulfate on the drying plate 32.

[0038] Working principle: Before using this device, the mass of water molecules emitted is calculated based on the mass of purified magnesium sulfate heptahydrate added. The springs inside the first spring sleeve 23 and the second spring sleeve 24 are then adjusted. The purified magnesium sulfate crystals are added into the device through the feeding port 11. The electric telescopic rod 31 extends and retracts, causing the drying plate 32 to reciprocate, which in turn causes the magnesium sulfate crystals on the drying plate 32 to vibrate, thus fully drying the magnesium sulfate crystals on the drying plate 32. At the same time, the reciprocating motion of the drying plate 32 causes the connecting plate 321 to reciprocate, which in turn causes the rack 322 to reciprocate. When the rack 322 rises, it causes the ratchet 323 to rotate, which in turn causes the fan 324 to rotate, thus circulating the hot air inside the second protective sleeve 13.

[0039] Simultaneously, the reciprocating motion of the drying plate 32 drives the piston 34 to reciprocate, sending the gas in the second protective sleeve 13 into the water-absorbing block 22 through the telescopic column 35 to absorb water, collecting the moisture generated after the magnesium sulfate crystals are dried. Meanwhile, the gas that has lost moisture enters the second air outlet pipe 233 through the first air outlet pipe 214. The increased weight of the water collected in the water-absorbing block 22 causes it to descend, which in turn causes the fixed plate 213 to descend, compressing the first spring sleeve 23 at the bottom of the fixed plate 213. A spring sleeve 23 retracts, causing the blocking plate 232 to move. When the blocking plate 232 moves to the first hole and contacts the second vent pipe 233, the gas in the second vent pipe 233 enters the vent pipe 234 through the blocking plate 232. By squeezing the squeezing plate 237, the squeezing plate 237 removes the water in the water-absorbing block 22, causing the blocking plate 232 to reset, facilitating the next drying operation. At the same time, most of the water inside the second protective sleeve 13 is removed, facilitating the subsequent collection of dried magnesium sulfate crystals.

[0040] Simultaneously, the fixed plate 213 descends, causing the second spring sleeve 24 to contract. The second spring sleeve 24 descends, causing the first connecting rod 241 to descend. The first connecting rod 241 descends, causing the second connecting rod 242 to descend. When the second connecting rod 242 descends, the second magnet 244 on the second connecting rod 242 attracts the limiting block 245, causing the limiting block 245 to flip, so that the rotating door 26 is not restricted by the limiting block 245. At the same time, when the second connecting rod 242 descends to a certain extent, the first magnet 243 attracts the rotating door 26, causing the rotating door 26 to flip, opening the second protective sleeve 13. This makes it convenient for workers to collect the dry magnesium sulfate inside the second protective sleeve 13. At the same time, due to the reciprocating motion of the piston 34, most of the moisture in the second protective sleeve 13 is removed, preventing the magnesium sulfate inside the second protective sleeve 13 from coming into contact with moisture when the rotating door 26 flips, which would cause dampness and affect the drying effect.

[0041] The water squeezed by the extrusion plate 237 is inside the filter disc 21, and the water in the filter disc 21 is transported to the water tank 12 through the water outlet pipe 211 by the water pump 212.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
