[0002] Sodium bromate is an inorganic compound that is often used as an analytical reagent and oxidant. It plays an important role in chemical experiments, especially in scenarios where oxidation reactions are required. A drying and packaging machine is required to prepare sodium bromate. The drying and packaging machine integrates drying and packaging functions, greatly improving production efficiency and product quality. It can dry and package various chemical materials (such as powders, granules, etc.). The drying and packaging machine usually includes a drying system, a packaging system and a control system. When working, the drying system generates hot air to dry the sodium bromate in the silo, thereby removing moisture. The dried sodium bromate enters the packaging bag through the discharge pipe, is transported by a conveyor belt, and is then packaged by a sealing machine.

[0003] In the prior art, during the drying process of the material, the drying and packaging machine discharges the hot air in the silo through the gas pipeline. The discharged hot air contains particulate matter, and the hot air and particulate matter easily accumulate in the gas pipeline, which can easily cause the pipeline to become blocked, thereby affecting the drying efficiency and packaging quality. In addition, the cleaning and maintenance of the blocked pipeline are relatively troublesome, which increases production costs. Summary of the Invention

[0009] Preferably, a limiting frame is provided on both sides of the gear ring inside the gas transmission pipeline, and a limiting groove is provided on both sides of the gear ring.

[0010] Preferably, the gear ring and the gas pipeline form a rotating structure through a limiting groove and a limiting frame, and the limiting frame is composed of an arc plate and an annular plate.

[0011] Preferably, a through groove is provided at the bottom end of the gas transmission pipeline, and a collecting frame matching the through groove is provided through the interior of the silo.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] The following describes an embodiment of the present invention based on its overall structure.

[0023] A drying and packaging machine with gas pipeline anti-clogging, such as Figure 1 and Figure 2 As shown, it includes a conveyor belt 1, a No. 1 mounting frame 2 and a No. 2 mounting frame 3. The top of the conveyor belt 1 is sequentially provided with the No. 2 mounting frame 3 and the No. 1 mounting frame 2 from right to left. A sealing machine 6 is installed on the inner side of the No. 1 mounting frame 2. A silo 4 is provided on the inner side of the No. 1 mounting frame 2. A drying mechanism 9 is provided on the right side of the silo 4. The drying mechanism 9 is composed of a fan 901, a heater 902 and an air inlet pipe 903. A fan 901 and a heater 902 are sequentially installed on the right side of the silo 4 from bottom to top. The heater 902 is composed of an outer box and an electric heating wire. An air inlet pipe 903 is connected between the heater 902 and the silo 4. A gas pipeline 7 is provided on the left side of the silo 4. A discharge pipe 5 is provided at the bottom end of the silo 4.

[0024] See Figure 1 and Figure 2 It can be seen that the fan 901 sends air into the heater 902, which is heated by the heater 902 to become hot air. At the same time, it is sent into the silo 4 through the air inlet pipe 903 to dry the sodium bromate in the silo 4, thereby removing moisture. The dried sodium bromate enters the packaging bag through the discharge pipe 5, is transported by the conveyor belt 1, and is then packaged by the sealing machine 6.

[0025] See Figure 1 、 Figure 3 and Figure 4It can be seen that a filter screen 10 is provided inside the gas pipeline 7, and an anti-blocking mechanism 8 is provided inside the gas pipeline 7 on one side of the filter screen 10. The anti-blocking mechanism 8 includes a drive motor 801, a gear 802, a gear ring 803 and an anti-blocking brush 804. The gear ring 803 is movably connected to the inner side of the gas pipeline 7, and the anti-blocking brush 804 is arranged on the inner side of the gear ring 803. The drive motor 801 is installed at the top of the gas pipeline 7. The outer surface of the output end of the drive motor 801 is provided with a gear 802 meshing with the gear ring 803. The anti-blocking brush 804 consists of a brush plate and an L-shaped plate, and two L-shaped plates are symmetrically provided about the longitudinal axis of the gear ring 803.

[0026] See Figure 1 、 Figure 3 and Figure 4 As can be seen, the filter 10 can block and filter particulate matter in the hot air, preventing it from entering the gas pipeline 7 and causing blockage. At the same time, because the ring gear 803 is meshed with the gear 802, when the drive motor 801 is in operation, the output end of the drive motor 801 drives the gear 802, the ring gear 803, and the anti-blocking brush 804 to rotate together. Therefore, the anti-blocking brush 804 can regularly clean the filter 10, preventing particulate matter from accumulating on the filter 10 and causing clogging of the filter holes, thereby ensuring smooth discharge of hot air. The present utility model can ensure the smooth flow of the gas pipeline 7, reduce the frequency of cleaning and maintenance of the gas pipeline 7, thereby improving production efficiency and extending the service life.

[0027] See Figure 3 and Figure 4 It can be seen that a limit frame 14 is provided on both sides of the gear ring 803 inside the gas pipeline 7, and a limit groove 13 is provided on both sides of the gear ring 803. The gear ring 803 and the gas pipeline 7 form a rotating structure through the limit groove 13 and the limit frame 14. The limit frame 14 is composed of an arc plate and an annular plate, which supports and limits the gear ring 803, enhances the stability of the gear ring 803 during rotation, and prevents it from tilting and offsetting.

[0028] See Figure 1 、 Figure 3 and Figure 4 It can be seen that a through groove 12 is provided at the bottom end of the gas pipeline 7, and a collecting frame 11 matching the through groove 12 is provided inside the silo 4. The collecting frame 11 is connected to the gas pipeline 7 through a magnetic block. The collecting frame 11 is used to collect the brushed particles for centralized processing, and the collecting frame 11 can be separated from the gas pipeline 7 by pulling the collecting frame 11 outward.

[0029] The working principle of this utility model is:

[0030] When the present invention is in use, the fan 901 sends air into the heater 902, which is heated by the heater 902 to become hot air. At the same time, the air is sent to the hopper 4 through the air inlet pipe 903, so that the sodium bromate in the hopper 4 is dried, thereby removing moisture. The dried sodium bromate enters the packaging bag through the discharge pipe 5, is transported by the conveyor belt 1, and then is packaged by the sealing machine 6. During this process, the moist hot air is discharged through the air pipeline 7, and at the same time, the particulate matter in the hot air is blocked and filtered by the filter 10 to prevent it from entering the inside of the air pipeline 7 and causing blockage; when the filter 10 needs to be cleaned, the drive motor 801 is started, and the output end of the drive motor 801 drives the gear 802, the ring gear 803 and the anti-blocking brush 804 to rotate together, so that the filter 10 can be regularly cleaned by the anti-blocking brush 804 to prevent particulate matter from accumulating on the filter 10 and causing blockage of the filter holes, thereby ensuring smooth discharge of hot air.
