It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0032] like Figure 1-Figure 5 As shown, the utility model provides a vacuum drying equipment for producing chemical reagent additives, including a drying box 1, a box door 2 is hinged on the side wall of the drying box 1, a heat pipe 3 is fixedly connected to the inner wall of the drying box 1, a plurality of electric heating wires 9 are fixedly connected to the inner wall of the drying box 1, a fan 4 is fixedly connected to the outer wall of the drying box 1, an air inlet end of the fan 4 is fixedly connected and communicated with the heat pipe 3, a temperature sensor 5 is fixedly connected to the inner wall of the drying box 1, a vacuum pump 6 is fixedly connected to the outer wall of the drying box 1 and communicated, an adjustment structure 7 is provided on the inner wall of the drying box 1, and a filtering structure 8 is provided at one end of the heat pipe 3.

[0033] The specific settings and functions of the regulating structure 7 and the filtering structure 8 are described in detail below.

[0034] like Figure 3 and Figure 4As shown, the adjustment structure 7 includes a motor 701, which is fixedly mounted on the outer wall of the drying box 1, and the output end of the motor 701 is fixedly connected to a support rod 702, which is located in the drying box 1, and the arc surface of the support rod 702 is provided with a plurality of slots 703, and the plurality of slots 703 are equally divided into two groups, and the arc surface of the support rod 702 is provided with two connecting slots, which are respectively connected to the two groups of slots 703, and the inner wall of the slot 703 is connected with a block 705, and the surface of the block 705 is fixedly connected with a perforated plate 706, and the perforated plate 706 is slidably connected to the support rod 702, and the size of the block 705 is adapted to the size of the connecting slot 704, and a baffle 707 is slidably connected in the support rod 702, and the baffle 707 passes through the connecting slot 704, and the baffle The upper end of 707 is fixedly connected with a connecting plate 708. When the blocking rod 707 passes through the connecting groove 704, the blocking rod 707 can prevent the block 705 from sliding out from the inner wall of the slot 703, thereby limiting the position of the orifice plate 706. The upper surface of the connecting plate 708 is rotatably connected with a blocking block 709. The blocking block 709 is threadedly connected to the drying box 1. When the blocking block 709 is rotated, the blocking block 709 will move into the drying box 1 with the help of the thread. The blocking block 709 will block the drying box 1 to prevent air from flowing into the drying box 1 through the gap between the connecting plate 708 and the drying box 1. The upper surface of the orifice plate 706 is fixedly connected with a flange 710. The flange 710 can prevent the solid raw material from sliding off the surface of the orifice plate 706 during the rotation of the orifice plate 706.

[0035] like Figure 5 As shown, the filtering structure 8 includes an extension frame 81, which is fixedly connected and communicated with the heat pipe 3. The arc surface of the extension frame 81 is engaged with a ring 82, and the inner wall of the ring 82 is fixedly connected with a filter block 83. The inner thread of the ring 82 is connected with a bolt 84, and the bolt 84 passes through the ring 82 and abuts against the outer wall of the extension frame 81. The bolt 84 is rotated. When the bolt 84 abuts against the arc surface of the extension frame 81, the bolt 84 reaches the function of limiting the position of the ring 82, thereby limiting the position of the filter block 83. The arc surface of the ring 82 is fixedly connected with a U-shaped plate 85, and the U-shaped plate 85 is fixedly connected to the ring 82. The bolt 84 is located in the U-shaped plate 85. The U-shaped plate 85 can limit the moving distance of the bolt 84 to prevent the bolt 84 from being out of contact with the ring 82.

[0036] The overall working principle is that when drying the raw materials of solid chemical reagent additives, the solid raw materials are placed on the orifice plate 706, and then the box door 2 is closed, and then the vacuum pump 6 is turned on, and the vacuum pump 6 will draw the inside of the drying box 1 into a vacuum state, and then the fan 4 and the electric heating wire 9 are turned on, and the electric heating wire 9 will heat the heat pipe 3, so that the inside of the drying box 1 is heated by the heat pipe 3, and then the solid raw materials are dried, and then the motor 701 is turned on, and the output end of the motor 701 will drive the support rod 702 to rotate, and the support rod 702 will drive the card block 705 to rotate, and the card block 705 will rotate. Block 705 will drive the orifice plate 706 to rotate, so as to evenly dry the solid raw materials. The flange 710 can prevent the solid raw materials from sliding off the surface of the orifice plate 706 during the rotation of the orifice plate 706. When it is necessary to dry solid raw materials of different volumes, the blocking block 709 is rotated, and the blocking block 709 moves upward with the help of the thread. The connecting plate 708 follows the movement of the blocking block 709 to drive the blocking rod 707 to move. When the blocking block 709 is out of contact with the drying box 1, the blocking block 709 moves upward to pull the blocking rod 707 out of the support rod 702, and then By rotating the orifice plate 706, the orifice plate 706 will drive the block 705 to slide from the inner wall of the slot 703 into the connecting slot 704, and then the position of the orifice plate 706 can be adjusted in the vertical direction. After the orifice plate 706 is adjusted to a suitable position, the orifice plate 706 is rotated in the opposite direction to make the block 705 slide into the slot 703 again. The slot 703 reaches the position of limiting the block 705, thereby limiting the position of the orifice plate 706. By adjusting the position of the orifice plate 706 according to the volume of the solid raw material, solid raw materials of different sizes can be conveniently placed on the orifice plate 706 for drying. , thereby expanding the application scope of the vacuum drying equipment, and then moving the blocking block 709 again to insert the blocking rod 707 into the support rod 702. When the blocking rod 707 passes through the connecting groove 704, the blocking rod 707 can prevent the block 705 from sliding out of the inner wall of the slot 703, thereby limiting the position of the orifice plate 706. Then the blocking block 709 is rotated, and the blocking block 709 will move into the drying box 1 with the help of threads. The blocking block 709 will block the drying box 1 to prevent air from flowing into the drying box 1 through the gap between the connecting plate 708 and the drying box 1.

[0037] When air needs to be filtered during the process of flowing into the heat conducting pipe 3, the ring 82 is put on the arc surface of the extension frame 81, and then the bolt 84 is rotated. When the bolt 84 is against the arc surface of the extension frame 81, the bolt 84 reaches the position of the limiting ring 82, thereby limiting the position of the filter block 83. At this time, the filter block 83 can filter the air flowing into the heat conducting pipe 3, thereby preventing foreign matter such as dust from adhering to the inner wall of the heat conducting pipe 3 and affecting the normal operation of the heat conducting pipe 3. When the filter block 83 needs to be removed, the bolt 84 is rotated in the opposite direction. When the bolt 84 is out of contact with the extension frame 81, the ring 82 can be removed from the arc surface of the extension frame 81, thereby removing the filter block 83. In this process, the U-shaped plate 85 can limit the moving distance of the bolt 84 to prevent the bolt 84 from being out of contact with the ring 82.
