Description

Technical Field

[0001] The utility model relates to the technical field of matting agent centrifugation, in particular to a centrifugal device for producing matting agent. Background Technique

[0002] Patent Publication No. CN219615811 U provides a crystal dehydration centrifuge for producing whitening agent, including a bracket and a housing. The housing is installed at the top of the bracket. A centrifugal tank is arranged at the center inside the housing. One side of the centrifugal tank is fixedly connected with a connecting shaft, and the other end of the connecting shaft is fixedly connected with a driving shaft. The driving shaft is installed on the main shaft of a motor, and the motor is installed on the surface of a connecting platform. In this utility model, by manually rotating a turning handle, the gear disc at one end of the turning handle rotates. When the gear disc rotates, the gear connection between the gear disc and the connecting gear is such that the connecting gear drives the centrifugal tank to rotate, so as to manually dehydrate the centrifugal tank. This solution has both manual and electric functions. At the same time, the dehydrated crystals can be stirred by a rotating shaft fan. When the rotating shaft fan rotates counterclockwise, the crystals can flow along the blades on the rotating shaft fan to the feeding port, so that the dehydrated crystals flow out from the feeding port, and then the crystals can be quickly discharged.

[0003] Crystals of different batches or types usually require different centrifugal forces to achieve the best separation effect. To change the centrifugal force in the above technology, the rotation speed of the motor needs to be frequently changed. Although technologies such as frequency converters can achieve the adjustment of the motor rotation speed, it will also increase the power consumption, thus increasing the use cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a centrifugal device for producing matting agent.

[0005] The technical problem solved by the utility model is: to change the way of adjusting the centrifugal force and reduce the power consumption.

[0006] The utility model can be realized by the following technical solutions: including a sealed box fixedly installed at the top of an installation frame, a centrifugal tank is rotatably installed inside the sealed box. A driven rotating rod is rotatably installed between the installation frame and the sealed box. One end of the driven rotating rod is fixedly connected with one side of the centrifugal tank. A driving rotating rod parallel to the driven rotating rod is rotatably installed on the installation frame. A speed change mechanism for adjusting the rotation speed of the driven rotating rod is arranged between the driving rotating rod and the driven rotating rod.

[0007] A further technical improvement of the utility model lies in that: one end of the centrifugal tank is fixedly communicated with a feeding port that penetrates and is rotatably connected with one side of the sealed box. A guide vane is fixedly installed inside the cavity of the centrifugal tank, and the guiding end of the guide vane is fixedly connected with the inlet of the feeding port.

[0008] Further, a threaded plug is threadedly connected to the inner peripheral wall of the feeding port.

[0009] Further, a liquid outlet pipe is fixedly connected to the bottom of the sealed box, and a valve is installed on the liquid outlet pipe.

[0010] Further, the speed change mechanism includes a first fixed frustum fixedly installed on the outer peripheral wall of the driven rotating rod. A first sliding frustum symmetrical to the first fixed frustum is also slidably installed on the outer peripheral wall of the driven rotating rod. A spring sleeved on the outer peripheral wall of the driven rotating rod is fixedly installed between the first sliding frustum and the mounting frame. A second fixed frustum is fixedly installed at a position corresponding to the first fixed frustum on the outer peripheral wall of the driving rotating rod. A second sliding frustum is slidably installed at a position corresponding to the first sliding frustum on the outer peripheral wall of the driving rotating rod. A transmission belt is provided between the driving rotating rod and the driven rotating rod. One end of the transmission belt is sleeved between the first fixed frustum and the first sliding frustum, and the other end of the transmission belt is sleeved between the second fixed frustum and the second sliding frustum.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation manners, structures, features, and their effects of the present utility model as follows.

[0020] Please refer to Figures 1-3 As shown, this embodiment provides a centrifugal device for producing matting agent, including a mounting frame 1. A sealed box 2 is fixedly installed on the top of the mounting frame 1. A centrifugal tank 3 is rotatably installed in the sealed box 2. One end of the centrifugal tank 3 is fixedly communicated with a feeding port 4 that is rotatably connected through one side of the sealed box 2. A threaded plug 5 is threadedly connected to the inner peripheral wall of the feeding port 4. A guiding vane 6 is fixedly installed in the inner cavity of the centrifugal tank 3. The guiding end of the guiding vane 6 is fixedly connected to the entrance of the feeding port 4. A liquid outlet pipe 7 is fixedly communicated with the bottom of the sealed box 2. A valve is installed on the liquid outlet pipe 7;

[0021] When the threaded plug 5 is rotated clockwise, the threaded plug 5 will gradually move outward from the feeding port 4 until it completely moves out of the feeding port 4, so that the feeding port 4 is in an open state. On the contrary, it will gradually move inward to the feeding port 4 until it is completely inserted into the feeding port 4, so that the feeding port 4 is in a closed state. Open the feeding port 4 to introduce the matting agent into the centrifugal tank 3, rotate the centrifugal tank 3 clockwise to centrifuge the matting agent, so that the crystals in the matting agent are retained in the centrifugal tank 3, and the liquid in the matting agent is separated into the sealed box 2. When the separation of the matting agent crystals is completed, open the feeding port 4 again, rotate the centrifugal tank 3 counterclockwise, so that the centrifugal tank 3 drives the guiding vane 6 to guide the matting agent crystals in the centrifugal tank 3 to the feeding port 4, and the matting agent crystals are exported from the centrifugal tank 3 through the feeding port 4. Then open the liquid outlet pipe 7 to discharge the waste liquid separated in the sealed box 2;

[0022] A driven rotating rod 8 is rotatably installed between the mounting frame 1 and the sealed box 2. The end of the driven rotating rod 8 away from the mounting frame 1 is fixedly connected to one side of the centrifugal tank 3. A fixed frustum 9 is fixedly connected to the outer peripheral wall of the driven rotating rod 8. A sliding frustum 10 symmetric to the fixed frustum 9 is also slidably installed on the outer peripheral wall of the driven rotating rod 8. A spring 11 sleeved on the outer peripheral wall of the driven rotating rod 8 is fixedly installed between the sliding frustum 10 and the mounting frame 1;

[0023] A driving rod 12 parallel to the driven rod 8 is rotatably installed on the mounting bracket 1. A driving motor for driving the driving rod 12 to rotate is installed on the mounting bracket 1. A second fixed frustum 13 is fixedly installed on the outer peripheral wall of the driving rod 12 corresponding to the position of the first fixed frustum 9. A second sliding frustum 14 is slidably installed on the outer peripheral wall of the driving rod 12 corresponding to the position of the first sliding frustum 10. A transmission belt 15 is provided between the driving rod 12 and the driven rod 8. One end of the transmission belt 15 is sleeved between the first fixed frustum 9 and the first sliding frustum 10, and the other end of the transmission belt 15 is sleeved between the second fixed frustum 13 and the second sliding frustum 14;

[0024] A rack plate 16 which is fixedly installed on the side of the second sliding frustum 14 away from the second fixed frustum 13 and is slidably connected through the mounting bracket 1. A gear 17 meshing with the rack plate 16 is rotatably installed on the mounting bracket 1 corresponding to the position of the rack plate 16. One end of the rotating shaft of the gear 17 is fixedly installed with a turning handle 18. The turning handle 18 is provided for facilitating the rotation of the gear 17;

[0025] Rotate the turning handle 18 in the clockwise direction, so that the gear 17 drives the second sliding frustum 14 to approach the second fixed frustum 13 through the rack plate 16. At this time, the inner peripheral wall size of the transmission belt 15 sleeved between the second fixed frustum 13 and the second sliding frustum 14 gradually becomes larger. Since the length of the transmission belt 15 is fixed, the inner peripheral wall size of the transmission belt 15 sleeved on the outer peripheral walls of the first fixed frustum 9 and the first sliding frustum 10 will gradually become smaller. The gradually smaller inner peripheral wall of the transmission belt 15 will squeeze the second sliding frustum 14, so that the second sliding frustum 14 squeezes the spring 11, so that the spring 11 is in a stressed state. Since the inner peripheral wall of the transmission belt 15 sleeved on the driven rod 8 becomes smaller, the rotation speed of the driven rod 8 becomes faster, so that the rotation speed of the centrifugal tank 3 becomes faster. On the contrary, the inner peripheral wall size of the transmission belt 15 sleeved on the outer peripheral walls of the first fixed frustum 9 and the first sliding frustum 10 will gradually become larger, the extrusion force of the transmission belt 15 on the first sliding frustum 10 is gradually released, the stressed spring 11 gradually rebounds, the inner peripheral wall size of the transmission belt 15 sleeved on the driven rod 8 becomes larger, so the rotation speed of the driven rod 8 becomes slower, and then the rotation speed of the centrifugal tank 3 becomes slower.

[0026] When the utility model is in use, first open the material input port 4, import the matting agent to be processed into the centrifugal tank 3, then close the material input port 4, and then make the centrifugal tank 3 rotate clockwise to separate the matting agent crystals in the matting agent. According to the processing amount of matting agents in different batches, change the rotation speed of the centrifugal tank 3 to achieve the best separation effect for matting agent crystals with different total amounts. When the separation of matting agent crystals is completed, open the material input port 4 again, and then make the centrifugal tank 3 rotate counterclockwise, so that the centrifugal tank 3 guides the matting agent crystals in the centrifugal tank 3 to the material input port 4 through the guide vane 6, so that the matting agent crystals separated in the centrifugal tank 3 are discharged through the material input port 4. Then open the liquid outlet pipe 7 to discharge the liquid discharged from the matting agent into the closed box 2 from the closed box 2. Repeat the above steps to separate the next batch of matting agents.

[0027] The above is only a preferred embodiment of the present utility model, and it is not a limitation to the present utility model in any form. Although the present utility model has been disclosed as above with the preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form an equivalent embodiment within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
