Technical Field
[0001] This utility model relates to the technical field of pharmaceutical equipment, and in particular to an automatic blowing and dust removal chamber for the receiving channel of a raw herb warehouse. Background Technology
[0002] The existing method for purging the raw medicinal herb warehouse inlet channel involves an outdoor forklift operator manually opening the front door and using the forklift to transport the pallet containing the raw medicinal herb unpacking boxes from the container truck to the rotating rack in the inlet channel (the rotating rack needs to be manually moved and placed in a designated position beforehand). After the transport is completed, the outdoor forklift exits the inlet channel and the outdoor forklift operator manually closes the front door. The workers inside the inlet channel then manually use a compressed air gun and the rotating rack to blow away any foreign matter that may be attached to the outer surface of the raw medicinal herb unpacking boxes at close range. After the purging is completed, the rear door is manually opened, and the indoor forklift operator transports the purged pallet containing the raw medicinal herb unpacking boxes to the raw medicinal herb inspection area and manually closes the rear door.

Each air shower pipe 22 is provided with multiple nozzles 221, with a spacing of 0.5-1.5m, optionally 0.5-1m or 1-1.5m. In a preferred embodiment, the nozzles 221 are Venturi nozzles, with three nozzles 221 on each air shower pipe 22. Each air shower pipe 22 is also equipped with a damped, fixed-axis mechanism that can freely adjust and fix the nozzles 221, ensuring that the blowing angle does not change throughout the entire dust removal operation. In a preferred embodiment, the three nozzles 221 of the air shower pipe 22 are spaced 0.48m, 1.33m, and 2.43m above the ground, respectively, which can cover all the required blowing surfaces on the double-layered raw material unpacking box and tray with a blowing height of 2.2m, and the Venturi nozzles can deliver 4kg / cm³ of gas. 2 The compressed air is depressurized and increased to form a large flow of low-pressure purging air, which can improve the purging effect while reducing the risk of damage to the raw drug opening box.
[0049] Continue reading Figure 1-2In this embodiment, each air shower pipe 22 is rotatably connected to the inner wall of the dust removal chamber 1 via a universal joint. In a preferred embodiment, the rear end of each air shower pipe 22 is provided with a universal joint that can be rotated and adjusted. Each air shower pipe 22 can be, for example, a wall-mounted rocker arm type air shower pipe. In the working state, the angle between each air shower pipe 22 and the inner wall of the dust removal chamber 1 is 70-80°, which can be selected as 70-75° or 75-80°; in the working state, the distance between two air shower pipes 22 symmetrically arranged on both sides of the inlet channel 13 is 1-3m, which can be selected as 1-2m or 2-3m. In a preferred embodiment, the air shower pipe 22 is set at 1 / 3 of the length of the inlet passage. Before the blowing operation, the air shower pipe 22 is manually rotated to face the front door 11 and form a 75-degree angle with the inner wall of the dust removal chamber 1. The distance between the corresponding nozzles 221 on the two sides of the air shower pipe 22 after rotation is 2m, which can cover the raw material unpacking box and pallet with a blowing width of 1.1m.
[0050] In this embodiment, the radar monitoring device 3 is located below the gas storage device 21. The distance between the radar monitoring device 3 and the bottom of the dust removal chamber 1 is 0.4-0.6m, optionally 0.4-0.5m or 0.5-0.6m. The detection range of the radar monitoring device 3 (the maximum range at which the radar can detect a target and generate a signal response) is 0.3-6m, optionally 0.3-2m, 2-4m or 4-6m. It is used to detect and identify whether the tray 5 containing the raw medicinal herb box, which enters from the outside in, enters the radar detection area 31. In a preferred embodiment, the radar monitoring device 3 is located between the front door 11 and the blowing unit 2, at a distance of 0.5m from the bottom of the dust removal chamber 1, and its detection range is 0.3-6m.
[0051] Please see Figure 1 and Figure 3 The process of using this utility model:
[0052] Step 1) The outdoor forklift operator manually opens the front door 11, adjusts the air shower pipe 22 to the appropriate position, and then adjusts the knob on the first control panel 6 to the automatic blowing position.
[0053] Step 2) The outdoor forklift operator transports the pallet 5 containing the raw medicinal materials to the radar detection area 31. After the radar monitoring device 3 detects the pallet entering from the outside, it outputs a signal to the first control panel 6.
[0054] Step 3) After the outdoor forklift operator exits the loading passage 13, they manually close the front door 11. Upon receiving the door-closed signal, the switch signal feedback unit 4 connected to the front door 11 sends a signal to the second control panel 7. After receiving the door-closed feedback signal, the second control panel 7 transmits the door-closed feedback signal to the first control panel 6. Upon receiving the feedback signal, the first control panel 6 outputs a command signal to the solenoid pneumatic valve 211 and activates it. Compressed air is input into the air storage device 21 through the compressed air supply pipe 24. The compressed air in the air storage device 21 is then transmitted to the air shower pipe 22, and the nozzles 221 on the air shower pipe 22 blow-clean the raw material packaging box and pallet, ensuring the removal of foreign matter adhering to the outer surface.
[0055] After step 4) purging is completed, the second control panel 7 controls the rear door 12 to open after a delay (in a preferred embodiment, this is set to 7 seconds, which can be adjusted according to actual conditions). After the indoor forklift operator removes the purged pallet 5 containing the raw herb opening box from the rear door 12, they manually close the rear door 12. Upon receiving the door closing signal, the switch signal feedback unit 4 connected to the rear door 12 outputs a command signal to the second control panel 7, controlling the front door 11 to open, and begins purging the second pallet 5 containing the raw herb opening box, repeating steps 1)-4) into automatic control mode.
[0056] Step 5) After the dust removal operation is completed, turn the knob on the first control panel 6 to the stop blowing position and turn off the automatic blowing device. Finally, return the air shower pipe 22 to the wall position so as not to obstruct passage or other operations.
[0057] In summary, this utility model transforms the original manual dust removal operation in the raw material warehouse's receiving channel into a completely new automatic dust removal chamber, avoiding the health risks to workers caused by manual dust removal. The delayed opening setting of the rear door 12 helps the purifier fully absorb the floating dust generated during dust removal. The automatic dust removal chamber operation achieves the goals of saving manpower and improving efficiency, avoiding the various impacts of this dust removal operation on the health and efficiency of workers. It provides a good model for enterprises to reduce burdens and increase efficiency, which is conducive to the sustainable development of enterprises.
