Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying device for granules. Background Technology

[0002] A granule dryer is a device used to dry granular drugs. Its working principle is mainly to heat the drying chamber through a heating structure and stir the granular drugs through a stirring structure, so that the granular drugs come into contact with the inner wall of the drying chamber, thereby achieving the purpose of drying the granular drugs. A granule drying device with publication number CN208952600U includes a drying chamber, several supporting columns are provided at the bottom of the drying chamber, a vibration box is provided in the drying chamber, several shock-absorbing pads are provided at the bottom of the drying chamber, the vibration box is placed on the shock-absorbing pads, and a motor box is installed on the upper surface of the drying chamber.

[0003] Existing granule dryers still have some problems during use. For example, during the drying process, a large amount of granules needs to be poured into the drying chamber and stirred, causing the granules to clump together inside the chamber. This prevents the granules from fully contacting the inner wall of the drying chamber, which may lead to uneven heating of the granules and thus affect the drying effect. Therefore, we propose a granule drying device to solve the above problems. Utility Model Content

[0036] In practical use, the second motor 601 can drive the crossbar 603 to rotate, and the crossbar 603 can drive the cross plate 604 to rotate, so that the cross plate 604 can block the inside of the feed box 6, thereby blocking the granules and preventing them from falling down. Each time the cross plate 604 rotates 90°, the cross plate 604 can carry the granules down, thereby controlling the amount of granules falling into the feed port 605. Moreover, the feed port 605 is set with a conical structure, so that the granules can flow into the surface of the conveyor belt 206 in sequence through the feed port 605, thereby preventing the granules from piling up and flowing into the surface of the conveyor belt 206.

[0037] In this embodiment, the baffle 705 is adapted to the interior of the slot 703, and the slider 706 and the groove 701 are sliding structures.

[0038] In practical use, by rotating the threaded rod 704, the threaded rod 704 moves up and down inside the threaded tube 702, which can simultaneously drive the baffle 705 to move. This allows for adjustment of the length of the baffle 705 extending out of the slot 703, thereby pushing the granules that are piled up on the conveyor belt 206 flat, preventing the granules from piling up and affecting the drying effect. At the same time, the distance between the bottom of the baffle 705 and the conveyor belt 206 can be adjusted according to the size of the granules, making it suitable for granules of different sizes and improving its practicality.

[0039] Meanwhile, the slider 706 moves inside the slide groove 701, thereby limiting the vertical position of the baffle 705 and improving the stability of the movement of the baffle 705.

[0040] In this embodiment, the electric heating rods 803 are arranged in an array structure.

[0041] In practical use, the granules conveyed on the conveyor belt 206 can be heated and dried by the electric heating rod 803.

[0042] In this embodiment, both first mounting plates 606 correspond to the two fixing plates 201, and the third threaded hole 607 corresponds to the first threaded hole 207. The first bolts 608 are threadedly connected to the third threaded hole 607 and the first threaded hole 207.

[0043] In practical use, the two first mounting plates 606 correspond to the two fixed plates 201, so that the unloading box 6 can be installed on the fixed plate 201. The unloading box 6 can be fixed by tightening the first bolt 608 into the third threaded hole 607 and the first threaded hole 207, making the unloading box 6 easy to disassemble and transport.

[0044] In this embodiment, the two second mounting plates 804 correspond to the two fixing plates 201, the fourth threaded hole 805 corresponds to the second threaded hole 208, and the second bolts 806 are threadedly connected to the fourth threaded hole 805 and the second threaded hole 208.

[0045] In practical use, the two second mounting plates 804 correspond to the two fixed plates 201, so that the drying box 8 can be installed on the fixed plate 201. The second bolts 806 are tightened into the fourth threaded hole 805 and the second threaded hole 208, thereby fixing the drying box 8, making it easy to disassemble and transport.

[0046] In this embodiment, the inside of the discharge hopper 3 gradually narrows from left to right, and the discharge hopper 3 gradually tilts downward from left to right.

[0047] In practical use, the dried granules on the conveyor belt 206 can flow into the discharge hopper 3 in sequence, and then flow out in sequence through the discharge hopper 3.

[0048] In this embodiment, the controller 5 is electrically connected to the first motor 202, the second motor 601, and the temperature sensor 801.

[0049] In practical use, the controller 5 can control the working status of the first motor 202, the second motor 601, and the temperature sensor 801, and the temperature sensor 801 can monitor the temperature inside the drying oven 8 in real time; and the controller 5 is equipped with a display, which can display the temperature monitored by the temperature sensor 801 in real time.

[0050] The working principle of the granule drying device mentioned in this utility model is as follows:

[0051] First, connect the controller 5, the first motor 202, the second motor 601, and the temperature sensor 801 to an external power supply. The controller 5 can control the working status of the first motor 202, the second motor 601, and the temperature sensor 801, and the temperature sensor 801 can monitor the temperature inside the drying oven 8 in real time. The controller 5 is equipped with a display, which can display the temperature monitored by the temperature sensor 801 in real time.

[0052] In use, the granules can be put into the feeding box 1 through the feeding hopper 602; then the second motor 601 can drive the crossbar 603 to rotate, and the crossbar 603 can drive the cross plate 604 to rotate, so that the cross plate 604 can block the granules inside the feeding box 6, thereby blocking them and preventing them from falling down. Each time the cross plate 604 rotates 90°, the cross plate 604 can carry the granules down, thereby controlling the amount of granules falling into the feeding port 605. The feeding port 605 is set with a conical structure, so that the granules can flow into the surface of the conveyor belt 206 through the feeding port 605 in sequence.

[0053] Then, the first motor 202 can drive the rollers 203 to rotate, so that the two rollers 203 can drive the conveyor belt 206 to rotate, thereby enabling the conveyor belt 206 to transport the granules;

[0054] Then, by rotating the threaded rod 704, the threaded rod 704 moves up and down inside the threaded tube 702, which simultaneously drives the baffle 705 to move. This allows adjustment of the length of the baffle 705 extending out of the slot 703, thus flattening the granules piled on the conveyor belt 206 and preventing them from affecting the drying effect. The distance between the bottom of the baffle 705 and the conveyor belt 206 can be adjusted according to the size of the granules, making it suitable for different sizes of granules and improving practicality. Furthermore, by moving the slider 706 inside the chute 701, the vertical position of the baffle 705 can be limited, improving the stability of its movement.

[0055] Then, the granules conveyed on the conveyor belt 206 can be heated and dried by the electric heating rod 803 inside the drying chamber 8;

[0056] Then the dried granules on the conveyor belt 206 can flow into the discharge hopper 3 in sequence, and then flow out through the discharge hopper 3 in sequence to complete the drying work;

[0057] Meanwhile, since both first mounting plates 606 correspond to the two fixed plates 201, the unloading box 6 can be installed on the fixed plate 201, and is tightened to the third threaded hole 607 and the first threaded hole 207 by the first bolt 608, thereby fixing the unloading box 6, making the unloading box 6 easy to disassemble and transport.

[0058] Meanwhile, the two second mounting plates 804 correspond to the two fixed plates 201, so that the drying box 8 can be installed on the fixed plate 201, and the second bolts 806 are tightened into the fourth threaded hole 805 and the second threaded hole 208, thereby fixing the drying box 8, making the drying box 8 easy to disassemble and transport.
