Technical Field
[0001] This utility model relates to the field of refractory material production technology, and more specifically, to a refractory material screening device with good screening effect. Background Technology
[0002] Refractory materials refer to inorganic non-metallic materials with a refractoriness of not less than 1580℃. They are used as structural materials for thermal equipment such as high-temperature kilns, as well as materials for industrial high-temperature containers and components. Common refractory materials include high-temperature resistant structural materials made from natural minerals such as bauxite, silica, magnesite, and dolomite. They are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate industry, power industry and other industrial fields.
[0003] In the production of refractory materials, in order to accurately screen raw materials, remove impurities, unevenly sized materials, and substandard products, and ensure that the quality of the produced refractory materials meets the standards, screening devices are usually used to screen the refractory materials. Since different refractory material products have different requirements for the particle size and shape of raw materials, the screening device can adjust the screening parameters according to production needs to ensure that the particle size of the raw materials meets the product requirements. Therefore, the screening device plays an irreplaceable role in the production of refractory materials.
[0004] Currently, when screening refractory materials, the particle size of the materials is usually uneven, so screening is necessary. However, during screening, a large amount of material to be screened accumulates on the screen, causing refractory material to pile up and affecting screening efficiency. Furthermore, the vibration of the material during screening generates a lot of dust, which affects the health of the workers. Therefore, it is necessary to improve and optimize the process.

[0007] The telescopic compartment is equipped with a top baffle, and the control compartment is equipped with a slider. The bottom of the slider is fixedly connected to the bottom feed plate. A connecting rod is fixedly installed on one side of the slider, and the other end of the connecting rod is fixedly connected to the top baffle.

[0010] As a preferred technical solution of this utility model, a guide groove is provided on the left side wall of the control chamber, the slider and the drive rod are fixedly connected, and the drive rod is movably installed inside the guide groove.
[0011] As a preferred embodiment of this utility model, a pusher block is fixedly installed inside the feeding tube, and the pusher block is located at the top of the bottom feeding plate and is in close contact with the bottom feeding plate.
[0012] As a preferred embodiment of this invention, the drive groove is shaped like a Luroxene triangle, and the drive groove is responsible for controlling the displacement of the drive rod along the guide groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model uses a motor to drive a drive disc to rotate, which in turn drives a slider to move via a drive rod. The slider then intermittently moves back and forth. When the slider is in the front position, the bottom feed plate receives the material. When the slider moves backward, it drives the bottom feed plate to move backward as well. A pusher block then pushes the material on top of the bottom feed plate into the screening chamber. Compared to traditional devices, this device allows for batch feeding of materials.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figures 1 to 9 As shown, this utility model provides a refractory material screening device with good screening effect, including a screening chamber 1, a feeding pipe 2 fixedly installed on the top of the screening chamber 1, a discharge port 3 on the right side of the screening chamber 1, a discharge port 4 on the front side of the screening chamber 1, a telescopic chamber 5 fixedly installed on the front side of the feeding pipe 2, and a control chamber 7 fixedly installed on the rear side of the feeding pipe 2.
[0031] The telescopic chamber 5 is equipped with a top baffle 6, and the control chamber 7 is equipped with a slider 14. The bottom of the slider 14 is fixedly connected to the bottom discharge plate 16. A connecting rod 15 is fixedly installed on one side of the slider 14, and the other end of the connecting rod 15 is fixedly connected to the top baffle 6.
[0032] A transmission rod 12 is rotatably installed inside the control compartment 7. A drive disk 9 is rotatably installed on the left side of the control compartment 7. The drive disk 9 and the transmission rod 12 are fixedly connected. A motor 8 is fixedly installed on the right side wall of the control compartment 7. The output shaft of the motor 8 is fixedly connected to the transmission rod 12. A drive groove 10 is opened inside the drive disk 9. A drive rod 13 is movably installed inside the drive groove 10.
[0033] When workers need to screen refractory materials, they first feed the material into the feed pipe 2, where it accumulates on top of the bottom feed plate 16. Then, they start motor 8 and motor 23. Motor 23 drives the vibrating block 24 to rotate, continuously lifting the transmission plate 21. After one revolution, the transmission plate 21 returns to its original position via the elastic potential energy of the spring 22. The transmission plate 21 then vibrates up and down, driving the screening plate 19 to vibrate up and down via the column 20, thus achieving the screening operation. Meanwhile, motor 8 drives the transmission rod 12 to rotate, which rotates synchronously with the drive disc 9. The drive rod 13 is movably mounted inside the drive groove 10, causing the drive groove 10 to drive the slider 14 to move via the drive rod 13. The path is restricted by the guide groove 11, causing the slider 14 to move back and forth intermittently. When the slider 14 is in the front position, the bottom feed plate 16 receives the material. When the slider 14 moves backward, the slider 14 drives the bottom feed plate 16 to move backward. The pusher block 17 pushes the material on the top of the bottom feed plate 16 into the screening chamber 1. The top baffle 6 also moves backward to prevent the material from falling continuously. At this time, the material is fed in batches. After the material falls into the top of the screening plate 19, the material will be vibrated and screened. Some of the material will be discharged from the discharge port 3 along the screening plate 19, while the other part of the material will fall from the screening plate 19 into the top of the guide plate 25. It will be further guided by the guide plate 25 to the discharge port 4 and discharged from the discharge port 4, thus achieving screening. During the screening, the top baffle 6 and the bottom feed plate 16 will isolate the feed pipe 2 and the screening chamber 1 to prevent the material from popping out.
[0034] The operation of motor 8 drives the drive disc 9 to rotate, causing the drive groove 10 to drive the slider 14 to move through the drive rod 13. Furthermore, the slider 14 begins to move back and forth intermittently. When the slider 14 is in the front position, the bottom feed plate 16 receives the material. When the slider 14 moves backward, the slider 14 drives the bottom feed plate 16 to move backward. Furthermore, the pusher block 17 pushes the material on the top of the bottom feed plate 16 into the screening chamber 1. Compared with traditional devices, this device can realize the batch input of materials. Moreover, during material screening, the top baffle 6 and the bottom feed plate 16 will isolate the feed pipe 2 and the screening chamber 1 to prevent materials from popping out, avoid the problem of material accumulation and blockage, and improve screening efficiency.
[0035] The screening chamber 1 has fixed grooves 18 on both the front and rear sides. A screening plate 19 is movably installed inside the screening groove 18. Columns 20 are fixedly installed at the four corners of the bottom of the screening plate 19. The four columns 20 penetrate to the bottom of the screening groove 18 and are fixedly connected to the transmission plate 21. The transmission plate 21 and the screening groove 18 are elastically connected by springs 22.
[0036] The operation of motor 23 drives the vibrating block 24 to rotate. When the vibrating block 24 rotates, it continuously lifts the transmission plate 21 upward. After the vibrating block 24 rotates one revolution, the transmission plate 21 will return to its original position downward through the elastic potential energy of the spring 22. Furthermore, the transmission plate 21 begins to vibrate up and down. The transmission plate 21 drives the screening plate 19 to vibrate up and down through the column 20, thus realizing the screening operation. After the material falls into the top of the screening plate 19, the material will be vibrated and screened. Some of the material will be discharged from the discharge port 3 along the screening plate 19, while the other part of the material will fall from the screening plate 19 into the top of the guide plate 25 and be further guided by the guide plate 25 to the discharge port 4, and discharged from the discharge port 4.
[0037] The vibrating block 24 is driven to rotate by the motor 23, which continuously lifts the transmission plate 21 upward. At the same time, while the vibrating block 24 provides vibration power, the transmission plate 21 will return to its original position downward through the elastic potential energy of the spring 22, so that the transmission plate 21 is always in contact with the vibrating block 24. Compared with the traditional device, this device starts the vibrating screening operation of the screening plate 19 through the operation of the vibrating block 24, so that the material is turned over on the surface of the screening plate 19, which can effectively improve the screening efficiency. At the same time, it is simple to operate, has a simple structure, and is convenient for subsequent maintenance.
[0038] The control compartment 7 has a guide groove 11 on its left side wall, and the slider 14 and the drive rod 13 are fixedly connected, with the drive rod 13 movably installed inside the guide groove 11.
[0039] The guide groove 11 is responsible for guiding the movement path of the drive rod 13 and ensuring that the slider 14 can move back and forth.
[0040] The feeding pipe 2 has a pusher block 17 fixedly installed inside. The pusher block 17 is located on top of the bottom feeding plate 16 and is in close contact with the bottom feeding plate 16.
[0041] As the slider 14 moves backward, it drives the bottom feed plate 16 to move backward, and the pusher block 17 pushes the material on top of the bottom feed plate 16 into the screening chamber 1.
[0042] The drive groove 10 is shaped like a Lurox triangle and is responsible for controlling the displacement of the drive rod 13 along the guide groove 11.
[0043] The shape of the drive groove 10 drives the drive rod 13 to move, thereby indirectly moving the slider 14 back and forth.
[0044] There are four sets of springs 22, all of which are elastically installed on the outer wall of the column 20.
[0045] After the vibrating block 24 rotates one revolution, the transmission plate 21 will return to its original position downwards through the elastic potential energy of the spring 22, ensuring the stable operation of the vibrating screening.
[0046] The screening chamber 1 is equipped with a vibrating block 24, and a motor 23 is fixedly installed on the rear side wall of the screening chamber 1. The output shaft of the motor 23 is fixedly connected to the vibrating block 24, and the bottom of the vibrating block 24 and the transmission plate 21 abut against each other.
[0047] The operation of motor 23 will drive the vibrating block 24 to rotate, and when the vibrating block 24 rotates, it will continuously lift the transmission plate 21 upward.
[0048] The screening chamber 1 is equipped with a guide plate 25, which is located below the screening plate 19.
[0049] With the guide plate 25 in place, the screened material is discharged through outlet 24.
[0050] Working principle and usage process of this utility model:
[0051] When workers need to screen refractory materials, they first feed the material into the feed pipe 2, where it accumulates on top of the bottom feed plate 16. Then, they start motor 8 and motor 23. Motor 23 drives the vibrating block 24 to rotate, continuously lifting the transmission plate 21. After one revolution, the transmission plate 21 returns to its original position via the elastic potential energy of the spring 22. The transmission plate 21 then vibrates up and down, driving the screening plate 19 to vibrate up and down via the column 20, thus achieving the screening operation. Meanwhile, motor 8 drives the transmission rod 12 to rotate, which rotates synchronously with the drive disc 9. The drive rod 13 is movably mounted inside the drive groove 10, causing the drive groove 10 to drive the slider 14 to move via the drive rod 13. The path is restricted by the guide groove 11, causing the slider 14 to move back and forth intermittently. When the slider 14 is in the front position, the bottom feed plate 16 receives the material. When the slider 14 moves backward, the slider 14 drives the bottom feed plate 16 to move backward. The pusher block 17 pushes the material on the top of the bottom feed plate 16 into the screening chamber 1. The top baffle 6 also moves backward to prevent the material from falling continuously. At this time, the material is fed in batches. After the material falls into the top of the screening plate 19, the material will be vibrated and screened. Some of the material will be discharged from the discharge port 3 along the screening plate 19, while the other part of the material will fall from the screening plate 19 into the top of the guide plate 25. It will be further guided by the guide plate 25 to the discharge port 4 and discharged from the discharge port 4, thus achieving screening. During the screening, the top baffle 6 and the bottom feed plate 16 will isolate the feed pipe 2 and the screening chamber 1 to prevent the material from popping out.
