Description

Technical Field

[0001] This utility model relates to the field of powder feeding equipment, and in particular to a feeding device for cyanuric acid powder. Background Technology

[0002] Cyanuric acid is a weakly acidic white crystalline powder and a key raw material in the synthesis of TGIC (triglycidyl isocyanurate). During the synthesis reaction, ton bags containing cyanuric acid powder are moved above a hopper, and then the powder is unloaded into the hopper through the discharge channel at the bottom of the ton bags. Finally, it is conveyed into the synthesis reactor through a screw conveyor at the bottom of the hopper for the synthesis reaction. However, the process of unloading the powder into the hopper generates a large amount of dust, which diffuses throughout the workshop environment, resulting in some waste of cyanuric acid powder. Exposure to this dust can also harm the health of workers, potentially damaging their skin and respiratory system. Furthermore, the discharge channel at the bottom of the ton bags is prone to blockage during unloading, typically requiring manual tapping with a stick to clear the blockage and ensure smooth powder flow, which is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a feeding device for cyanuric acid powder to solve the related problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a feeding device for cyanuric acid powder, including a frame, a feeding hopper set on the frame and an auger feeding pipe set at the discharge end of the feeding hopper. A dust cover is set at the upper end of the feeding hopper, the bottom of the dust cover is adapted to the opening of the feeding hopper, and a feeding port adapted to the bottom unloading channel of the ton bag is opened at the top of the dust cover. A first ventilation gap is left between the inner wall of the feeding port and the outer wall of the bottom unloading channel of the ton bag. An auxiliary feeding cylinder is set on the feeding port. The inner diameter of the auxiliary feeding cylinder is adapted to the inner diameter of the feeding port. A second ventilation gap is left between the inner wall of the auxiliary feeding cylinder and the outer wall of the bottom unloading channel of the ton bag. A beating device is set inside the auxiliary feeding cylinder. A dust suction port is set on the dust cover. A dust suction pipe is connected to the dust suction port. A dust suction device is connected to the dust suction pipe.

[0005] Furthermore, the patting device includes a set of patting plates, patting plate support rods disposed on the patting plates, and a patting cylinder connected to the other end of the patting plate support rods. The auxiliary feeding cylinder has support rod through holes on its cylinder wall that are adapted to the patting plate support rods.

[0006] To facilitate the feeding of the ton bag into the bottom unloading channel, a funnel-shaped feeding hopper is provided at the upper end of the auxiliary feeding cylinder.

[0007] To facilitate maintenance and repair of the feeding hopper by opening the dust cover, the dust cover is closable and is installed on the feeding hopper. A hinge is provided between the dust cover and the feeding hopper, and the dust cover can be opened by rotating around the hinge.

[0008] Preferably, the dust cover is provided with a flipping arm, one end of which is fixed to the dust cover, and the other end is hinged to a flipping cylinder, the other end of which is hinged to the frame.

[0009] To facilitate observation of the inside of the dust cover, a transparent observation window is also provided on the dust cover.

[0010] To achieve dust collection, the dust collection device includes a dust collection chamber, a partition disposed within the dust collection chamber, the partition dividing the dust collection chamber into a first chamber and a second chamber, an air inlet disposed on the side wall of the second chamber, a set of filter elements fixed to the partition disposed within the second chamber, an exhaust port disposed on the partition connecting to the filter elements, a fan disposed above the exhaust port in the first chamber, an air outlet disposed on the first chamber, and a powder receiving box disposed at the lower end of the second chamber.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a dust cover to enclose the feeding hopper. The bottom unloading channel of the ton bag extends from the auxiliary feeding cylinder into the dust cover for unloading. The dust generated during unloading is contained by the dust cover to prevent its spread. Then, a dust suction device sucks the dust from inside the dust cover through a suction pipe and filters it for recycling. This not only saves costs and prevents material waste but also prevents dust from spreading throughout the factory workshop and coming into contact with operators, thus ensuring their health. Simultaneously, a clapping cylinder drives a clapping plate to clap the outer wall of the bottom unloading channel of the ton bag, ensuring that the material slides smoothly onto the feeding hopper, preventing blockages, saving time and effort, and eliminating the need for manual clapping. A funnel-shaped guide hopper is installed at the top of the auxiliary feeding cylinder to facilitate the entry of the bottom unloading channel of the ton bag into the auxiliary feeding cylinder. The retraction of the telescopic part of the tilting cylinder causes the dust cover to rotate and open around the hinge, facilitating the maintenance of the feeding hopper.

[0019] like Figures 1 to 6 As shown, a feeding device for cyanuric acid powder includes a frame 1, a feeding hopper 2 mounted on the frame 1, and an auger feed pipe 3 mounted on the discharge end of the feeding hopper 2. A dust cover 4 is provided at the upper end of the feeding hopper 2, the bottom of the dust cover 4 is adapted to the opening of the feeding hopper 2, and a feeding port 5 is provided at the top of the dust cover 4, which is adapted to the bottom unloading channel of the ton bag. A first ventilation gap 10 is left between the inner wall of the feeding port 5 and the outer wall of the bottom unloading channel of the ton bag. An auxiliary feeding cylinder 6 is provided on the feeding port 5. The inner diameter of the auxiliary feeding cylinder 6 is the same as the inner diameter of the feeding port 5, and a second ventilation gap 20 is left between the inner wall of the auxiliary feeding cylinder 6 and the outer wall of the bottom unloading channel of the ton bag. A trumpet-shaped guide hopper 8 is connected to the upper end of the auxiliary feeding cylinder 6. The dust cover 4 is equipped with a dust suction port 41, which is connected to a dust suction pipe 42, and the dust suction pipe 42 is connected to a dust suction device 7. In actual operation, the ton bag is hoisted above the funnel-shaped guide hopper 8 using a hoisting device, and then the bottom unloading channel of the ton bag is lowered. The bottom unloading channel of the ton bag is guided into the auxiliary feeding cylinder 6 along the funnel-shaped guide hopper 8, and then through the feeding port 5 so that the opening of the bottom unloading channel of the ton bag enters the dust cover 4. A large amount of dust raised during feeding is absorbed by the dust suction device 7. When the dust suction device 7 generates negative pressure, air from outside the dust cover 4 enters the dust cover 4 through the second vent gap 20 and the first vent gap 10, thereby achieving dust suction. At the same time, under the action of negative pressure, air flows into the dust cover 4 through the second vent gap 20 and the first vent gap 10, which also prevents dust from escaping from the second vent gap 20 and the first vent gap 10.

[0020] To prevent material blockage in the bottom unloading channel of the ton bag, a tapping device 61 is provided inside the auxiliary feeding cylinder 6. The tapping device 61 includes a set of tapping plates 611, a tapping plate support rod 612 set on the tapping plates 611, and a tapping cylinder 613 connected to the other end of the tapping plate support rod 612. The tapping cylinder 613 is fixed on the outer wall of the auxiliary feeding cylinder 6, and a support rod through hole 62 adapted to the tapping plate support rod 612 is provided on the cylinder wall of the auxiliary feeding cylinder 6. The dispersing cylinder 613 drives the dispersing plate support rod 612 to move back and forth, which in turn drives the dispersing plate 611 to move back and forth, striking the outer surface of the bottom unloading channel of the ton bag. The automatic striking device 61 allows the powder to slide smoothly out of the bottom unloading channel of the ton bag, avoiding blockage. It eliminates the need for operators to manually strike the material next to the feeding hopper, saving time and effort, and also preventing operators from coming into contact with the dust. To prevent the dispersing plate 611 from scraping against the bottom unloading channel of the ton bag during its up and down movement, the inner wall of the feeding cylinder 6 is provided with a relief groove 63 that matches the dispersing plate 611. In the initial state, the dispersing plate 611 is located in the relief groove 63.

[0021] To facilitate maintenance and repair of the inside of the feeding hopper 2, the dust cover 4 is closable and hinged to the feeding hopper 2. A hinge 43 connects the dust cover 4 to the feeding hopper 2, allowing the dust cover 4 to rotate and open. For easy opening of the dust cover 4, a tilting arm 44 is provided. One end of the tilting arm 44 is fixed to the dust cover 4, and the other end is hinged to a tilting cylinder 45, the other end of which is hinged to the frame 1. The dust cover 4 is opened by the retraction of the telescopic part of the tilting cylinder 45, which, through the tilting arm 44, causes the dust cover 4 to tilt outward via the hinge 43. It should be noted that the suction pipe 42 is a flexible hose that can twist and bend as the dust cover 4 tilts. For easy observation, the dust cover 4 is also provided with a transparent observation window 46. The transparent observation window 46 includes a fixed frame 461 and a transparent glass 462 disposed on the fixed frame 461. The dust cover 4 is provided with mounting holes 47 for mounting the fixed frame 461.

[0022] The vacuuming device 7 includes a vacuuming chamber 71. A partition 72 is horizontally arranged inside the vacuuming chamber 71, dividing it into a first chamber 73 and a second chamber 74. An air inlet 78, which connects to the vacuuming pipe 42, is located on the side wall of the second chamber 74. A set of filter elements 75 fixed to the partition 72 is located inside the second chamber 74. An exhaust port 721, which connects to the filter elements 75, is located on the partition 72. A fan 79 is located above the exhaust port 721 in the first chamber 73, and an air outlet 76 is located on the first chamber 73. A powder receiving box 77 is located at the lower end of the second chamber 74. Suction generated by the fan 79 draws the powder raised inside the dust cover 4 out through the vacuum inlet 41, along the vacuuming pipe 42, into the second chamber 74, where it is filtered out by the filter elements 75. The filtered powder is then collected by the powder receiving box 77. The dust collection chamber 71 is equipped with an openable door 711, which allows the powder receiving box 77 to be removed. It should be noted that the filter element 75 is existing technology and will not be described in detail here.
