Description
Technical Field
[0001] This utility model relates to the field of magnesium sulfate production technology, specifically a dehydration device for magnesium sulfate production. Background Technology
[0002] Magnesium sulfate is an important inorganic chemical product. Its industrial production mainly adopts the acid-base neutralization method, in which dilute sulfuric acid with a concentration of 20-30% is added to a reaction vessel, and magnesium hydroxide powder is slowly added under stirring conditions. After the reaction is completed, an aqueous solution of magnesium sulfate is obtained. In order to obtain solid magnesium sulfate product, the water in the magnesium sulfate solution needs to be removed.
[0003] Existing technologies typically involve concentration and crystallization followed by centrifugal separation. During the use of the centrifugal dehydration device, the magnesium sulfate solid-liquid mixture adheres to the inner wall of the cylinder. This adhesion layer hinders liquid flow, affects the solid-liquid separation effect, and leads to an increase in the water content of the separated solid, resulting in excessive water content in the product and affecting subsequent drying processes and the quality of the final product. In view of this, we propose a dehydration device for magnesium sulfate production. Utility Model Content
[0004] The purpose of this invention is to provide a dehydration device for magnesium sulfate production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dehydration device for magnesium sulfate production, comprising a shell, an air outlet on the side wall of the shell, a baffle hinged to the side wall of the shell, and a drying assembly disposed inside the shell, the drying assembly comprising:
[0006] A drying tube is fixedly connected to the inner wall of the housing. A filter plate is fixedly connected to the inner wall of the housing. An inclined tube is fixedly connected to the side wall of the drying tube. An atomizing tube is fixedly connected to the inner wall of the inclined tube. A groove is opened on the inner wall of the drying tube. A heating tube is fixedly connected to the inner wall of the drying tube.
[0007] The motor has a rotating rod fixedly connected to its output end, a fan blade fixedly connected to the side wall of the rotating rod, a scraper fixedly connected to the side wall of the rotating rod, and a brush fixedly connected to the side wall of the rotating rod.
[0008] Preferably, an atomizing nozzle is fixedly connected to one end of the atomizing tube near the drying tube, and a filter screen is fixedly connected to the other end of the drying tube away from the filter plate. The filter screen purifies the air entering the drying tube to prevent excessive impurities from entering.
[0009] Preferably, the drying tube is fixedly connected to the inner wall of the housing, and a bracket is fixedly connected to the inner wall of the drying tube, and the bracket is fixedly connected to the motor.
[0010] Preferably, the scraper is movably connected to the inner wall of the drying tube, and the heating tube is located on the side of the fan blades near the filter plate. The heating tube heats the air to accelerate the evaporation of water in the magnesium sulfate solution.
[0011] Preferably, the brush is movably connected to the filter plate, which is located on the side of the air outlet near the drying tube. The rotating rod rotates to drive the brush to rotate, thereby cleaning the surface of the filter plate.
[0012] Preferably, the brush is hinged to the brush plate, and an elastic element is fixedly connected to the outer wall of the brush plate. The end of the elastic element away from the brush plate is fixedly connected to the brush. The elastic element pushes the brush to fit against the filter plate, and the movement of the brush plate cleans the surface of the filter plate, sweeping the magnesium sulfate powder onto the inner bottom surface of the housing.
[0013] Preferably, a trapezoidal block is fixedly connected to one end of the filter plate near the filter plate, and the trapezoidal block is movably connected to the brush plate.
[0014] Compared with the prior art, this utility model provides a dehydration device for magnesium sulfate production, which has the following beneficial effects:
[0015] 1. This dehydration device for magnesium sulfate production uses a drying component to spray atomized magnesium sulfate solution in the form of tiny droplets. Heated air directly contacts the atomized magnesium sulfate solution, and with the help of high-speed airflow, the water in the magnesium sulfate solution is evaporated, preventing crystal agglomeration and resulting in a magnesium sulfate product with uniform particle size. During the dehydration process, the atomizing tube atomizes the solution into fine droplets, preventing the magnesium sulfate solution from contacting the inner surface of the device. This reduces the adhesion of the solution to the inner wall of the equipment and lowers the risk of equipment blockage. The cleaning action of the scraper and brush ensures that magnesium sulfate crystals are promptly removed from the surface of the drying tube and filter plate, preventing crystals from adhering for a long time and causing agglomeration or deterioration. At the same time, it avoids increased airflow resistance due to blockage. The unobstructed airflow channel allows the hot air to fully contact the magnesium sulfate solution, improving heat exchange efficiency and accelerating water evaporation.
[0016] 2. This dehydration device for magnesium sulfate production uses trapezoidal blocks and brush plates. The movement of the brush plates cleans the surface of the filter plates. The brush plates can create a knocking force on the filter plates, which can effectively shake off stubborn magnesium sulfate powder, improve cleaning efficiency, and the dynamic contact and knocking action of the brushes can promptly clean the magnesium sulfate powder on the surface of the filter plates, prevent the powder from accumulating and clogging the filter plate pores, and ensure smooth airflow.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a dehydration device for magnesium sulfate production, including a shell 1, an air outlet 2 on the side wall of the shell 1, a baffle 3 hinged to the side wall of the shell 1, and a drying assembly 4 inside the shell 1. The drying assembly 4 includes a drying tube 401, an inclined tube 402, an atomizing tube 403, a support 404, a motor 405, a rotating rod 406, a fan blade 407, a heating tube 408, a scraper 409, a groove 410, a filter plate 411, and a brush 412.
[0024] In one embodiment of this utility model, a drying tube 401 is fixedly connected to the inner wall of the housing 1, a filter plate 411 is fixedly connected to the inner wall of the housing 1, a filter screen 5 is fixedly connected to the end of the drying tube 401 away from the filter plate 411, the filter screen 5 purifies the air entering the drying tube 401 to prevent excessive impurities from being mixed in, an inclined tube 402 is fixedly connected to the side wall of the drying tube 401, an atomizing tube 403 is fixedly connected to the inner wall of the inclined tube 402, an atomizing nozzle is fixedly connected to the end of the atomizing tube 403 near the drying tube 401, a slot 410 is opened on the inner wall of the drying tube 401, and a heating tube 408 is fixedly connected to the inner wall of the drying tube 401.
[0025] The drying tube 401 is fixedly connected to the inner wall of the housing 1. A bracket 404 is fixedly connected to the inner wall of the drying tube 401. The bracket 404 is fixedly connected to the motor 405. A rotating rod 406 is fixedly connected to the output end of the motor 405. A fan blade 407 is fixedly connected to the side wall of the rotating rod 406. A scraper 409 is fixedly connected to the side wall of the rotating rod 406. The scraper 409 is movably connected to the inner wall of the drying tube 401. A heating tube 408 is located on the side of the fan blade 407 near the filter plate 411. The heating tube 408 heats the air to accelerate the evaporation of water in the magnesium sulfate solution. A brush 412 is fixedly connected to the side wall of the rotating rod 406. The brush 412 is movably connected to the filter plate 411. The filter plate 411 is located on the side of the air outlet 2 near the drying tube 401. The rotation of the rotating rod 406 drives the brush 412 to rotate, thereby cleaning the surface of the filter plate 411.
[0026] Motor 405 drives rotor 406 and fan blade 407 to rotate, thereby blowing external air toward filter plate 411. Heating tube 408 heats the incoming air. The atomized magnesium sulfate solution is sprayed out in the form of tiny droplets. The heated air comes into direct contact with the atomized magnesium sulfate solution. Combined with the high-speed airflow, the water in the magnesium sulfate solution is evaporated, preventing crystal agglomeration and obtaining a magnesium sulfate product with uniform particle size. During the dehydration process, atomizing tube 403 atomizes the solution into fine droplets. The magnesium sulfate solution does not come into contact with the inner surface of the device, reducing the adhesion of the solution to the inner wall of the equipment and reducing the risk of equipment blockage.
[0027] The rotation of the rotating rod 406 drives the scraper 409 and the brush 412 to rotate. The rotation of the scraper 409 removes the magnesium sulfate crystals adhering to the inner surface of the drying tube 401, allowing the magnesium sulfate crystals to fall into the interior of the housing 1 through the slot 410. The brush 412 removes the magnesium sulfate crystals from the surface of the filter plate 411, allowing the airflow carrying moisture to pass through the filter plate 411 and the air outlet 2 and be discharged from the housing 1. The cleaning action of the scraper 409 and the brush 412 ensures that the magnesium sulfate crystals are promptly removed from the surface of the drying tube 401 and the filter plate 411, preventing the crystals from adhering for a long time and causing clumping or deterioration. At the same time, it avoids increased airflow resistance due to blockage. The unobstructed airflow channel allows the hot air to fully contact the magnesium sulfate solution, improving heat exchange efficiency and accelerating moisture evaporation.
[0028] In addition, the brush 412 is hinged to the brush plate 6, and an elastic element 7 is fixedly connected to the outer wall of the brush plate 6. The end of the elastic element 7 away from the brush plate 6 is fixedly connected to the brush 412. The elastic element 7 pushes the brush 412 to fit against the filter plate 411. The movement of the brush plate 6 cleans the surface of the filter plate 411 and sweeps the magnesium sulfate powder onto the inner bottom surface of the housing 1. A trapezoidal block 8 is fixedly connected to the end of the filter plate 411 near the filter plate 411. The trapezoidal block 8 is movably connected to the brush plate 6. The trapezoidal block 8 lifts the brush plate 6. When the brush plate 6 passes the trapezoidal block 8, it re-contacts the filter plate 411 under the elastic action of the elastic element 7, forming a knocking force on the filter plate 411, which can effectively shake off the stubborn magnesium sulfate powder and improve the cleaning efficiency. The dynamic fitting and knocking action of the brush 412 can clean the magnesium sulfate powder on the surface of the filter plate 411 in time, prevent the powder from accumulating and clogging the pores of the filter plate 411, and ensure smooth airflow.
[0029] In this invention, during use, the motor 405 drives the rotating rod 406 and the fan blade 407 to rotate, thereby blowing external air towards the filter plate 411. The heating tube 408 heats the incoming air, and the atomized magnesium sulfate solution is sprayed out in the form of tiny droplets. The heated air directly contacts the atomized magnesium sulfate solution, and with the high-speed airflow, the water in the magnesium sulfate solution is evaporated, preventing crystal agglomeration and obtaining a magnesium sulfate product with uniform particle size. During the dehydration process, the atomizing tube 403 atomizes the solution into fine droplets, and the magnesium sulfate solution does not come into contact with the inner surface of the device, reducing the adhesion of the solution to the inner wall of the equipment and lowering the risk of equipment blockage. The rotation of the rotating rod 406 drives the scraper 40... 9. The brush 412 rotates, and the scraper 409 rotates to remove the magnesium sulfate crystals attached to the inner surface of the drying tube 401, allowing the magnesium sulfate crystals to fall into the interior of the housing 1 through the slot 410. The brush 412 removes the magnesium sulfate crystals from the surface of the filter plate 411, allowing the airflow to carry moisture through the filter plate 411 and the air outlet 2 to be discharged from the housing 1. The cleaning action of the scraper 409 and the brush 412 ensures that the magnesium sulfate crystals are removed from the surface of the drying tube 401 and the filter plate 411 in a timely manner, preventing the crystals from adhering for a long time and causing clumping or deterioration. At the same time, it avoids the increase in airflow resistance due to blockage. The unobstructed airflow channel allows the hot air to fully contact the magnesium sulfate solution, improves the heat exchange efficiency, and accelerates the evaporation of moisture.
[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
