Description

Technical Field

[0001] This invention relates to the field of microwave modification technology, specifically to a microwave modification line device and a microwave modification processing method. Background Technology

[0002] The principle of microwave modification is to activate bentonite by treating it with microwaves in the frequency band between 300Hz and 300GHz. Microwave treatment has the advantages of strong penetration, uniform heating, safe and simple operation, low energy consumption, and high efficiency. It achieves better results when used in combination with traditional acidification and calcination methods.

[0003] Existing microwave modification equipment requires the use of material bins to store the modified materials, and the movement of these bins allows the materials to enter various processing devices. However, the existing material bins result in uneven heating of the materials during material transfer, affecting the efficiency of microwave modification. Furthermore, existing microwave modification production equipment requires lifting mechanisms for transfer operations between components. These mechanisms are typically scissor lifts, which have limited minimum transfer distances, thus restricting their applicability, occupying significant space, and being unsuitable for production needs.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example: Please refer to Figure 1-7 This invention provides a technical solution: a microwave modification line device.

[0037] Example 1:

[0038] The system includes a main frame 1, a feeding mechanism 2, a transfer mechanism, a tray mechanism 4, a lifting mechanism 5, and a microwave chamber 6. Three microwave chambers 6 are located on the outer side of the main frame 1. The feeding mechanism 2 is located on the right side of the main frame 1, and a material box detection mechanism is located on the right side of the feeding mechanism. The material box detection mechanism is electrically connected to the PLC control system. A set of robotic arms is located at the feeding mechanism 2 and the material box detection mechanism. The robotic arms at the feeding mechanism 2 are used to feed materials into the hopper 201. The robotic arms are electrically connected to the PLC control system. Two sets of lifting mechanisms 5 are located on the left side of the main frame 1 and the right side of the feeding mechanism 2, respectively. The feeding mechanism 2 includes a hopper 201, with a support on the top of the hopper 201 and a discharge plate 202 at the discharge port of the hopper 201. The transfer mechanism includes a motor 3 on the left side of the main frame 1, with a main shaft at the output end of the motor 3 and a driven shaft on the right side of the main frame 1. The main frame 1 is divided into upper and lower layers. The upper layer has two shafts parallel to the main shaft and the driven shaft respectively. Gears are fitted around the main shaft, the driven shaft, and the two sets of shafts on the upper part, and a transmission sprocket 7 is fitted around the outside of the gears. The head and tail of the transmission sprocket 7 are engaged to form a closed rectangular circuit. The material tray mechanism 4 is movably mounted on the upper part of the transmission sprocket 7. The motor 3 drives the main shaft to rotate, which in turn drives the transmission sprocket 7 to rotate and transport the material tray mechanism 4.

[0039] Furthermore, a monitoring sensor is installed at the discharge port of the hopper 201, and the lifting mechanism 5 is connected to the main frame 1 through a connecting plate. The discharge plate 202 is parallel to the upper opening of the material box 405, and the upper opening of the material box 405 can be fully connected with the discharge plate 202.

[0040] Furthermore, the material tray mechanism 4 includes a bottom tray 401, a disc 402 on the upper part of the tray 401, a circular hole in the middle of the tray 401, a fixing rod 403 in the middle of the bottom of the disc 402, a toothed ring 404 on the lower part of the outer ring of the fixing rod 403, a track in the middle of the upper and lower sides of the main frame 1, a strip groove 8 in the inner cavity of the track, a locking tooth on one side of the inner wall of the strip groove 8, and the toothed ring 404 engaging in the strip groove 8 and meshing with the locking tooth.

[0041] In this embodiment, the material box is placed on the right side of the upper transmission sprocket 7, and then the material box detection mechanism detects the material box 405 and transmits the status of the material box 405 to the PLC control system. If the material box 405 is damaged, the robot arm removes the damaged material box 405 and picks up a new material box 405 and places it on the disc 402. If the material box 405 is detected as undamaged, the transmission sprocket 7 conveys the material tray mechanism 4 forward. When the monitoring sensor at the discharge port of the hopper 201 detects that the upper opening of the material box 405 is fully connected with the docking discharge plate 202, the valve of the hopper 201 opens to feed the material into the material box. After the feeding is completed, the valve of the hopper 201 automatically closes to wait for the next set of material tray mechanisms 4.

[0042] Example 2:

[0043] A microwave modification line device has three microwave chambers 6 arranged on the outside of the main frame 1. Each microwave chamber 6 consists of a microwave oven and a circulating water cooling system. The microwave chamber 6 is filled with nitrogen gas. A set of robotic arms is also arranged on the left side of the microwave chamber 6, which is located on the side of the main frame 1.

[0044] In this embodiment, the material tray mechanism 4 is conveyed forward by the drive sprocket into the microwave chamber 6. The microwave oven heats the material in the material box 405 to complete the modification, and then cools it down through a circulating water cooling system. The microwave chamber 6 has three identical sections. Continuing to convey the material tray mechanism 4 forward allows for three rounds of modification and cooling of the material in the material box 405. To prevent the material from burning due to overheating, the microwave chamber 6 is filled with nitrogen gas to protect the entire modification process. After modification, a robotic arm lifts the material box 405 and unloads it into the unloading hopper.

[0045] Example 3:

[0046] A microwave modification line device includes a material tray mechanism 4 comprising a bottom carrier tray 401, a disc 402 on the upper part of the carrier tray 401, a circular hole in the middle of the carrier tray 401, a fixing rod 403 at the middle of the bottom of the disc 402, a toothed ring 404 at the lower part of the outer ring of the fixing rod 403, and tracks in the middle of the upper and lower sides of the main frame 1. The inner cavity of the tracks has a strip groove 8, and a retaining tooth is provided on one inner wall of the strip groove 8. The toothed ring 404 engages with the strip groove 8 and meshes with the retaining tooth. Material boxes 405 are evenly distributed on the top of the disc 402, and vertical rods 406 are provided on both sides of the disc. A cover plate is provided on the upper part of the vertical rods 406, and the upper part of the material box 405 passes through the cover plate.

[0047] In this embodiment, when the material tray mechanism 4 is conveyed by the transmission sprocket 7, the toothed ring rolls in the strip groove 8, driving the fixed rod 403 to rotate, and then driving the disc 402 and the material box 405 on its top to rotate, which can make the material inside the material box 405 heat up evenly and better complete the material modification.

[0048] Example 4:

[0049] A microwave modification line device includes a lifting mechanism 5 comprising a main frame 501 and a protective cover 502 disposed outside the main frame 501. Slide rails 503 are symmetrically arranged on both sides of the main frame 501, and a transition seat 504 is disposed between the main frames 501. Slider blocks 505 are symmetrically arranged on the sides of the transition seat 504 and are slidably connected to the slide rails 503. A transmission box is disposed at the rear of the upper part of the main frame 501.

[0050] Furthermore, the inner cavity of the transmission box is symmetrically equipped with an upper pressure cylinder 9, and the lower part of the slide rail 503 is equipped with a lower pressure cylinder 10. The output ends of both the upper pressure cylinder 9 and the lower pressure cylinder 10 are equipped with telescopic rods 11, and the ends of the telescopic rods 11 are equipped with movable contacts 12. The position of the movable contacts 12 corresponds to the position of the slider 505.

[0051] Furthermore, the slide rail 503 has evenly spaced limit holes 506 on the side facing the slider 505, and the slider 505 has a slot on the side facing the slide rail 503. A spring is installed in the inner cavity of the slot, and a limit block is installed at the outer end of the spring. The limit block matches the model of the limit hole 506.

[0052] In this embodiment, when the tray mechanism 4 is driven to the leftmost position by the transmission sprocket 7, the robotic arm clamps the tray mechanism with the empty material box after it has been tilted and places it onto the adapter seat 504. Then, the upper pressure cylinder 9 drives the telescopic rod 11 to extend downward so that the movable contact 12 contacts the slider 505. The slider 505 continues to be pushed downward along the slide rail 503, causing the adapter seat 504 to move downward. At the same time, during the movement, the limiting block is squeezed and retracted into the slot. When the position of the limiting block coincides with the position of the limiting hole 506... The time limit block is pushed out by the spring, allowing the adapter 504 to stop at any position. When the time limit block aligns with the bottommost time limit hole, the top surface of the adapter 504 remains horizontal with the top surface of the lower transmission sprocket 7. At this point, the tray mechanism 4 is moved to the starting position to the right by the lower transmission sprocket, completing the cycle of the tray mechanism 4. Then, the lower pressure cylinder 10 drives the telescopic rod 11 and the movable contact 12 to push the slider 505 upward, returning the adapter 504 to the top, awaiting the lifting and lowering of the next set of tray mechanisms 4.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
