Abstract
Description
Technical Field
[0001] This utility model relates to the field of sodium chloride dehumidification technology, and in particular to a powdered sodium chloride electric heating dehumidification device. Background Technology
[0002] In the current dialysis powder production process, the sodium chloride raw material has a high water content, which makes it prone to clumping and inconvenient to produce. Therefore, it needs to be dried.
[0003] However, existing powdered sodium chloride dehumidification devices mostly employ single heating or simple stirring methods, exhibiting significant technical shortcomings: On the one hand, traditional devices lack efficient agglomeration and crushing structures, making it difficult for the internal moisture of agglomerated sodium chloride to fully contact the heat source, resulting in uneven drying; on the other hand, the material is mostly in a static accumulation or slow conveying state, with limited contact area with the heat medium, and water vapor easily forms a saturated humid air layer on the material surface, hindering further moisture discharge and resulting in low drying efficiency. Therefore, in response to the above situation, there is an urgent need to develop an electric heating dehumidification device for powdered sodium chloride that utilizes stirring and crushing mechanisms with stirring blades and triangular crushing blades. This device can ensure uniform heating of sodium chloride and break up agglomerated materials to facilitate moisture discharge. Furthermore, a lifting mechanism drives a reciprocating lifting mechanism to lift sodium chloride to the upper part of the dehumidification chamber, allowing it to disperse and fully contact the hot air as it falls, accelerating moisture discharge and significantly improving the drying efficiency and effect of powdered sodium chloride. This device overcomes the shortcomings in current practical applications and meets current needs. Utility Model Content
[0004] The purpose of this invention is to provide an electrically heated dehumidifying device for powdered sodium chloride to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dehumidification device for powdered sodium chloride using electric heating includes a dehumidification chamber, a stirring and crushing mechanism, a lifting mechanism, an air supply mechanism, a material lifting mechanism, pressure rods, and a heater. The dehumidification chamber is divided into upper and lower halves, with only the lower half used to hold the sodium chloride. The heater is installed in the lower half of the dehumidification chamber. The stirring and crushing mechanism is installed on the top of the dehumidification chamber and extends into its lower half. The lifting mechanism is installed on the top of the dehumidification chamber and extends into its interior. Multiple material lifting mechanisms are fixedly connected to the lower side of the lifting mechanism and inserted into the lower half of the dehumidification chamber. Multiple pressure rods are fixed to the top of the dehumidification chamber, each pressure rod facing one of the material lifting mechanisms. The air supply mechanism is inserted into the dehumidification box. The lifting mechanism includes an electric telescopic rod and an annular plate. There are two electric telescopic rods, which are fixed to the top of the dehumidification box. The telescopic ends of the electric telescopic rods are fixed to the annular plate. The material lifting mechanism includes a storage bin, a base plate, guide rods, springs, a frustum, and a cone. The storage bin is fixed to the bottom of the annular plate. The bottom of the storage bin is movably provided with a base plate. Multiple guide rods inserted into the outer wall of the storage bin are fixed on the base plate. The guide rods are slidably connected to the storage bin. A spring connected to the storage bin is installed at the upper end of each guide rod. A frustum is fixed on the upper side of the base plate, and a cone is fixed on the lower side of the base plate.
[0006] Preferably, the annular plate is provided with multiple through holes for the pressure rod to pass through.
[0007] Preferably, the stirring and crushing mechanism includes a drive motor, a transmission shaft, stirring blades, and triangular crushing blades. The drive motor is fixed on the dehumidification box, and the output shaft of the drive motor is fixed to the transmission shaft via a coupling. The lower half of the transmission shaft is fixed with stirring blades and triangular crushing blades.
[0008] Preferably, the air supply mechanism includes a hot air blower, an annular pipe, and air nozzles. The hot air blower is placed on the ground, and the air outlet of the hot air blower is connected to the annular pipe. Multiple air nozzles that are inserted into the dehumidification box are installed on the annular pipe.
[0009] Preferably, the top of the dehumidification box is provided with an exhaust pipe, and a one-way valve is installed on the exhaust pipe.
[0010] The beneficial effects of this utility model are as follows: When using this powdered sodium chloride electric heating dehumidification device, the sodium chloride to be dried is added to the lower half of the dehumidification chamber. Then, the heater is started for heating and drying. Simultaneously, the drive motor drives the transmission shaft, stirring blades, and triangular crushing blades to rotate. The stirring blades stir the sodium chloride to ensure more even heating, and the triangular crushing blades break up any clumps of sodium chloride, facilitating moisture drainage. After adding sodium chloride to the lower half of the dehumidification chamber, a portion of the sodium chloride enters the storage tank. Then, an electric telescopic rod moves the annular plate upwards, which in turn moves the storage tank to the upper half of the dehumidification chamber. This causes the pressure rod to gradually insert into the storage tank, pressing against the frustum and causing the bottom plate to move downwards to store the sodium chloride. The bottom of the barrel is opened, and the sodium chloride in the storage barrel slides outward along the inclined surface of the truncated cone, thus lifting the sodium chloride into the upper part of the dehumidification chamber for easy moisture discharge. Then, the lifting mechanism drives the lifting mechanism to move down to the lower part of the dehumidification chamber. Under the action of the spring force, the bottom plate blocks the storage barrel again. After moving down to the correct position, the sodium chloride flows back into the storage barrel. Then, the lifting mechanism moves up again, and so on, thus continuously lifting the sodium chloride from the lower part of the dehumidification chamber to the upper part. During the falling process, the sodium chloride disperses and comes into full contact with the hot air. The hot air is delivered to the annular pipe by the hot air blower and blown into the dehumidification chamber through multiple air nozzles. The hot air removes the moisture from the sodium chloride, improving the drying efficiency. In summary, this invention utilizes the stirring blades and triangular crushing blades of the stirring and crushing mechanism to ensure uniform heating of sodium chloride and break up clumps of material to facilitate moisture removal. The lifting mechanism drives the material lifting mechanism to reciprocate, lifting the sodium chloride to the upper part of the dehumidification box, allowing it to disperse and fully contact the hot air as it falls, accelerating the removal of moisture and significantly improving the drying efficiency and effect of powdered sodium chloride.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Specific implementation examples are given below.
[0022] See Figures 1-8 In this embodiment of the present invention, an electric heating dehumidification device for powdered sodium chloride includes a dehumidification box 1, a stirring and crushing mechanism 2, a lifting mechanism 3, an air supply mechanism 4, a material lifting mechanism 5, a pressure rod 6, and a heater 7. The dehumidification box 1 is divided into upper and lower halves, with only the lower half used to hold sodium chloride and the upper half empty. The heater 7 is installed in the lower half of the dehumidification box 1 and is used to heat the sodium chloride. The top of the dehumidification box 1 is provided with a feed inlet 101, and a plug 102 is detachably connected to the feed inlet 101 by a thread. The bottom of the dehumidification box 1 is provided with a discharge port 103, and an end cap 104 is detachably connected to the discharge port 103 by a thread. Sodium chloride is added from the feed inlet 101 and discharged from the discharge port 103.
[0023] The stirring and crushing mechanism 2 is installed on the dehumidification box 1 and extends into the lower half of the dehumidification box 1. The stirring and crushing mechanism 2 is used to stir the sodium chloride to make it heat more evenly. The stirring and crushing mechanism 2 includes: a drive motor 201, a transmission shaft 202, a stirring blade 203, and a triangular crushing blade 204. The drive motor 201 is fixed on the dehumidification box 1. The output shaft of the drive motor 201 is fixed to the transmission shaft 202 through a coupling. The stirring blade 203 and the triangular crushing blade 204 are fixed in the lower half of the transmission shaft 202. In use, the drive motor 201 drives the transmission shaft 202, the stirring blade 203, and the triangular crushing blade 204 to rotate. The stirring blade 203 stirs the sodium chloride to make it heat more evenly, and the triangular crushing blade 204 breaks up the clumps of sodium chloride to facilitate the drainage of water.
[0024] The lifting mechanism 3 is installed on the top of the dehumidification box 1 and extends into its interior. Multiple lifting mechanisms 5 are fixedly connected to the lower side of the lifting mechanism 3. The lifting mechanisms 5 are inserted into the lower half of the dehumidification box 1. Multiple pressure rods 6 are fixed at the top of the interior of the dehumidification box 1. Each pressure rod 6 is directly opposite a lifting mechanism 5. The lifting mechanism 5 is moved up and down by the lifting mechanism 3.
[0025] The lifting mechanism 3 includes: an electric telescopic rod 301 and an annular plate 302. There are two electric telescopic rods 301 and they are fixed to the top of the dehumidification box 1. The telescopic ends of the electric telescopic rods 301 are fixed to the annular plate 302. The annular plate 302 is provided with multiple through holes 3021 for the pressure rod 6 to pass through.
[0026] The material lifting mechanism 5 includes: a storage bin 501, a base plate 502, guide rods 503, springs 504, a frustum 505, and a cone 506. The storage bin 501 is fixed to the bottom of the annular plate 302. The base plate 502 is movably installed at the bottom of the storage bin 501. Multiple guide rods 503 are fixed on the base plate 502 and inserted into the outer wall of the storage bin 501. The guide rods 503 are slidably connected to the storage bin 501. A spring 504 connected to the storage bin 501 is installed at the upper end of each guide rod 503. A frustum 505 is fixed on the upper side of the base plate 502, and a cone 506 is fixed on the lower side of the base plate 502. During normal use, the base plate 502 is attached to the bottom of the storage bin 501 to block it. After sodium chloride is added to the lower half of the dehumidification box 1, a portion of the sodium chloride enters the storage bin 501. Then, it is lifted by the electric telescopic rod 3. 01 drives the annular plate 302 to move upward, which in turn drives the storage bin 501 to move upward into the upper part of the dehumidification box 1. This causes the pressure rod 6 to gradually insert into the storage bin 501. The pressure rod 6 squeezes the frustum 505, causing the bottom plate 502 to move downward and opening the bottom of the storage bin 501. The sodium chloride in the storage bin 501 slides outward along the inclined surface of the frustum 505, thus lifting the sodium chloride into the upper part of the dehumidification box 1 to facilitate the discharge of water vapor. Then, the lifting mechanism 3 drives the lifting mechanism 5 to move downward into the lower part of the dehumidification box 1. Under the elastic force of the spring 504, the bottom plate 502 blocks the storage bin 501 again. The cone 506 can reduce the resistance when inserting sodium chloride. After moving downward into place, the sodium chloride flows back into the storage bin 501. Then, the lifting mechanism 5 is moved upward again, and so on.
[0027] The air supply mechanism 4 is inserted into the dehumidification box 1. The air supply mechanism 4 includes a hot air blower 401, an annular pipe 402, and air nozzles 403. The hot air blower 401 is placed on the ground. The air outlet of the hot air blower 401 is connected to the annular pipe 402. Multiple air nozzles 403 are installed on the annular pipe 402 and inserted into the dehumidification box 1. When in use, the hot air blower 401 delivers hot air into the annular pipe 402 and blows the hot air into the dehumidification box 1 through the multiple air nozzles 403, thereby removing the moisture from the sodium chloride.
[0028] The top of the dehumidification box 1 is equipped with an exhaust pipe 8, and a one-way valve 801 is installed on the exhaust pipe 8. The one-way valve 801 allows the air inside the dehumidification box 1 to be discharged from the exhaust pipe 8, while the outside air cannot enter the dehumidification box 1 from the exhaust pipe 8. During dehumidification, water vapor is discharged from the bottom of the exhaust pipe 8 with the airflow.
[0029] A PLC controller 9 is installed on the ground on one side of the dehumidification box 1. The drive motor 201, electric telescopic rod 301, hot air blower 401, and heater 7 are electrically connected to the PLC controller 9 and are electrically controlled by the PLC controller 9.
[0030] Working Principle: In this powdered sodium chloride electric heating dehumidifier, the sodium chloride to be dried is added to the lower half of the dehumidifier 1 (i.e., only half the capacity of the dehumidifier 1 is filled). Then, the heater 7 is started for heating and drying. Simultaneously, the drive motor 201 drives the transmission shaft 202, stirring blade 203, and triangular crushing blade 204 to rotate. The stirring blade 203 stirs the sodium chloride to ensure more even heating, and the triangular crushing blade 204 breaks up any clumps of sodium chloride, facilitating moisture drainage. After the sodium chloride is added to the lower half of the dehumidifier 1, a portion of it enters the storage tank 501. Then, the electric telescopic rod 301 moves the annular plate 302 upwards, which in turn moves the storage tank 501 to the upper half of the dehumidifier 1. This causes the pressure rod 6 to gradually insert into the storage tank 501, compressing the frustum 505. The bottom of the storage bin 501 is opened when the bottom plate 502 moves down, and the sodium chloride in the storage bin 501 slides outward along the inclined surface of the frustum 505, thus raising the sodium chloride to the upper part of the dehumidification box 1 to facilitate the discharge of water vapor. Then, the lifting mechanism 3 drives the lifting mechanism 5 to move down to the lower part of the dehumidification box 1. Under the elastic force of the spring 504, the bottom plate 502 blocks the storage bin 501 again. After moving down to the position, the sodium chloride flows back into the storage bin 501. Then, the lifting mechanism 5 moves up again, and so on, so that the sodium chloride in the lower part of the dehumidification box 1 is continuously raised to the upper part. During the falling process, the sodium chloride disperses and comes into full contact with the hot air. The hot air is delivered to the annular pipe 402 by the hot air blower 401, and the hot air is blown into the dehumidification box 1 through multiple air nozzles 403. The hot air removes the moisture in the sodium chloride and improves the drying efficiency.
[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
