Description

Technical Field

[0001] The utility model belongs to the technical field of chemical production, and in particular relates to a chemical production drying device. Background Art

[0002] Chemical engineering is a technology that uses chemical methods to change the composition and structure of substances or synthesize new substances. It belongs to chemical production technology. The products obtained are called chemicals or chemical products. Initially, such products were produced in handicraft workshops, which later evolved into factories and gradually formed a specific production industry, namely the chemical industry. Many different chemical raw materials are used in the chemical production process, and people will dry these chemical raw materials before production to ensure the output quality of chemical products.

[0003] For example, a Chinese patent with publication number CN213363150U discloses a drying device for chemical production, which includes a box body, a drying box is rotatably installed inside the box body, a motor is installed on the lower wall of the box body through a support seat, the upper end of the motor driving end is fixedly connected to the lower wall of the drying box, a drying structure is installed on the lower wall of the box body, a feed inlet is opened on the left side of the upper wall of the box body, a discharge port is opened on the right side of the lower wall of the box body, a discharge pipe is connected to the right side of the lower wall of the drying box, and a valve is arranged on the discharge pipe; the drying device for chemical production has a reasonable structure, a novel design, and is easy to move. The drying structure and the electric heating wire can quickly and evenly dry the chemical raw materials, greatly improve the work efficiency, and are more convenient to use. It effectively solves the problem that the existing drying device has poor drying effect and uneven drying, resulting in severe local heating of the raw materials, thereby affecting the use of the raw materials.

[0004] This patent has some shortcomings when used, such as: the device in this patent is not equipped with a ventilation mechanism. When the raw materials are heated, the water in the raw materials evaporates from liquid to gas under the action of the drying mechanism and accumulates in the inner cavity of the box. When there is a lot of water vapor, the water vapor at the top is liquefied into small water droplets again and falls back into the raw materials below under the action of gravity, so that the raw materials still need to be dried twice, which reduces the drying efficiency of the device; in addition, the device in this patent realizes the contact between the raw materials at different positions in the box and the drying structure by rotating the drying box to achieve the purpose of drying, but during the rotation of the drying box, the water vapor generated by the raw materials at the middle and bottom of the box cavity when evaporating cannot be fully discharged, making it easy for higher water to accumulate in the middle of the box. In view of this, we propose a chemical production drying device. Utility Model Content

The fixing frame 11 is a U-shaped frame structure, and the lower surface of the fixing frame 11 is welded and fixed to the upper surface of the upper cover 5. A fan 12 is installed in the fixing frame 11. A protective mesh plate 13 is fixed to the opening at one end of the fixing frame 11.

[0046] In this embodiment, the stirring assembly includes:

[0047] The motor 14 is fixedly mounted at the center of the upper surface of the upper cover 5. The output shaft of the motor 14 passes through the upper surface of the upper cover 5 and extends to the inner cavity of the heat preservation box 1 and is coaxially connected with a driving wheel 15. A gear ring 16 fixed to the lower surface of the upper cover 5 is arranged on the circumferential side of the driving wheel 15. A plurality of driven wheels 17 equidistantly distributed on the circumference are arranged between the driving wheel 15 and the gear ring 16.

[0048] In this embodiment, the rotating shaft is fixedly mounted on the lower surface of the driving wheel 15 .

[0049] Among them, the working principle of this device is as follows:

[0050] When feeding, the electric hydraulic cylinder 7 is started, the telescopic rod of the electric hydraulic cylinder 7 moves upward, and pushes the upper cover 5 to move upward. At this time, the top opening of the drying box 2 is exposed to the outside world, and then the raw materials to be dried are put into the drying box 2. After the feeding is completed, the electric hydraulic cylinder 7 is started again, so that the telescopic rod of the electric hydraulic cylinder 7 moves downward, and the upper cover 5 is in a closed state;

[0051] At this time, the drying mechanism, the stirring component and the air suction component are started. When the drying mechanism works, the multiple electric heating tubes 4 are started, the multiple electric heating tubes 4 work and generate a lot of heat, and heat the drying box 2. The water in the raw material in the inner cavity of the drying box 2 evaporates due to the heat, and the water evaporates from liquid to gas and moves upward;

[0052] The air suction assembly works, the fan 12 works and generates negative pressure, the fan 12 sucks the air in the inner cavity of the annular cover 9 to the outside, and the high-temperature water vapor accumulated on the top of the inner cavity of the insulated box 1 enters the inner cavity of the annular cover 9 through the multiple exhaust holes 8 and is discharged to the outside at the same time;

[0053] In addition, in order to accelerate the drying of the moisture in the raw materials in the inner cavity of the drying box 2, the stirring component is started, and the motor 14 works at this time, the output shaft of the motor 14 rotates, and drives the driving wheel 15 to rotate, and the driving wheel 15 drives the multiple driven wheels 17 on the peripheral side to rotate. Under the action of the ring gear 16, the multiple driven wheels 17 perform a revolution motion with the driving wheel 15 as the axis. At this time, the multiple stirring rods 20 rotate with the driven wheel 17, and also perform a circular motion in the inner cavity of the drying box 2, so that the raw materials outside the inner cavity of the drying box 2 can be stirred, thereby accelerating the precipitation of water vapor in the raw materials. Furthermore, the rotating shaft drives the spiral blades 21 to rotate, and the spiral blades 21 transport the raw materials at the middle position of the inner cavity of the drying box 2 from the bottom to the top, so that the raw materials in the inner cavity of the drying box 2 are stirred by the multiple stirring rods 20, and the tumbling phenomenon occurs at the same time, so that the raw materials at various locations in the inner cavity of the drying box 2 can be fully stirred and heated, thereby accelerating the drying efficiency of the raw materials by the device.

[0054] By opening a plurality of exhaust holes 8 on the upper cover 5, and arranging an annular cover 9 and an air suction component on the upper cover 5, the air suction component is used to discharge the water vapor generated when the raw material is dried, so as to avoid the phenomenon that the water vapor accumulates on the lower surface of the upper cover 5 and liquefies again to form water droplets, thereby reducing the possibility of needing to perform secondary drying on the raw material; by arranging a material turning mechanism, the stirring component is used to tumble and stir the raw materials at various locations in the drying box 2 and simultaneously drive the rotating shaft and the spiral blade 21 to rotate; by arranging the spiral blade 21, the raw materials in the inner cavity of the drying box 2 are stirred by the plurality of stirring rods 20, and tumble at the same time, so that the raw materials at various locations in the inner cavity of the drying box 2 can be fully stirred and heated, thereby accelerating the drying efficiency of the raw materials by the device.
