Description

Technical Field

[0001] This utility model relates to the technical field of screening equipment, specifically a vibration screening device for fused gemstones. Background Technology

[0002] Calcined refractory clay is a high-quality hard refractory clay. Calcined refractory clay is characterized by stable composition, uniform texture, and dense structure. Its main chemical components are Al2O3 and SiO2, with small amounts of Fe2O3 and trace amounts of Na2O and K2O.

[0003] In order to accurately grade and deeply remove impurities, and to provide charred gemstone raw materials with uniform particle size and meeting purity standards for subsequent processing (such as brick making and sintered quartz sand), it is necessary to vibrate and screen the charred gemstone.

[0004] Currently, the vibratory screening of coke requires feeding it into vibrating screens of different grades, allowing the coke to pass through screens of different aperture sizes. This separates the coke into fixed particle size grades such as coarse, medium, and fine (e.g., 5-10mm, 1-5mm, and 200-mesh fine powder) to meet the stringent particle size requirements of downstream products (e.g., coarse particles for brick aggregate, and fine powder for refractory mortar production). However, repeatedly feeding the coke into screens of different aperture sizes reduces the efficiency of coke screening to some extent, and also necessitates the manufacture of screens with different aperture sizes and corresponding vibratory equipment. Utility Model Content

[0005] The purpose of this invention is to provide a vibrating screening device for calcined gemstones, which solves the problem that current screens cannot screen out calcined gemstones of different particle sizes, thereby improving the efficiency and quality of calcined gemstone production.

[0006] To achieve the above objectives, the utility model employs the following technical solution: A vibratory screening device for coke is provided, comprising a base and a screen box movably mounted on the base. The screen box is equipped with a vibrator, and the base is equipped with a motor that drives the vibrator to rotate. The screen box has several horizontal support plates and several vertical support plates mounted on the horizontal support plates. A screen plate is slidably connected to the vertical support plates. One side of the screen plate has an inclined surface, and a screening channel is formed between two adjacent inclined surfaces. The cross-section of the screening channel gradually increases from top to bottom. The screen box has several partitions that divide the screening process into several collection chambers. The bottom of the screen box has several discharge ports that communicate with the collection chambers.

[0007] Furthermore, the transverse support plate is provided with a plurality of transverse grooves, and one side of the sieve plate is provided with a plurality of sliding rods that pass through the vertical support plate and slide in contact with the transverse grooves.

[0008] Furthermore, the end of the slide rod is provided with a roller, and several eccentric wheels are rotatably connected to the transverse support plate. The two sides of the eccentric wheels are respectively provided with arc surfaces that contact the rollers, and a first spring is provided between the sieve plate and the vertical support plate.

[0009] Furthermore, the transverse support plate is provided with a rotating shaft that is rotatably connected to the eccentric wheel. One side of the eccentric wheel is provided with a plurality of first keyways. A limit block is slidably connected on the rotating shaft. One side of the limit block is provided with a plurality of first connecting keys that slide in contact with the first keyways. The limit block is provided with a plurality of second connecting keys. The rotating shaft is provided with a plurality of second keyways that slide in contact with the second connecting keys.

[0010] Furthermore, a fixing nut is provided at the end of the rotating shaft, and a second spring is provided between the fixing nut and the limiting block.

[0011] Furthermore, the vibrator includes a main shaft rotatably mounted on the screen box, and the main shaft is provided with a plurality of eccentric blocks.

[0012] Furthermore, the motor has a first pulley at its movable end, a second pulley rotatably connected to the base, and a belt sleeved on the outside of the first and second pulleys. A coupling is provided between the second pulley and the main shaft.

[0013] Furthermore, several rubber springs and dampers are provided between the screen box and the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. After the coke is fed into the screen box, the vibrator driven by the motor rotates on the screen box, causing the screen box to vibrate. This causes the coke on the screen plates to shake and fall, sequentially falling into the screening channel between the two screen plates. Simultaneously, because the cross-section of the screening channel gradually increases from top to bottom, coke with smaller apertures pass through the screening channel first and fall into the uppermost collection chamber. As the cross-section of the screening channel changes, the particle size of the coke that can pass through the screening channel gradually increases, allowing medium-sized coke and larger apertures to fall into their respective collection chambers in sequence. Then, through the corresponding discharge ports, they enter different subsequent processes, achieving simultaneous screening of coke with various apertures without having to feed them separately onto screens with different apertures. This improves the efficiency of screening coke and the efficiency and quality of producing various coke derivatives. Furthermore, it eliminates the need to manufacture screens with different apertures and the associated vibration equipment, thus reducing the cost of producing coke. 2. When the eccentric wheel is rotated counterclockwise on the horizontal support plate, the arc surface on the side of the eccentric wheel contacts the roller, and the resulting force drives the roller to move to both sides, thereby causing the screen plate to slide inward on the vertical support plate. When the eccentric wheel is rotated clockwise on the horizontal support plate, the arc surface on the side of the eccentric wheel does not contact the roller. Under the action of the first spring's rebound force, the horizontal support plate moves outward on the vertical support plate, thereby changing the distance between the two adjacent inclined planes, adjusting the cross-section of the screening channel, adapting to the screening needs under different conditions in the production of coke gemstones, and further improving the efficiency and quality of coke gemstone production. 3. After adjustment, the rebound force generated by the compression of the second spring causes the limiting block to slide downward on the rotating shaft, allowing the second connecting key to return to the second keyway. The resistance generated by the contact between the second connecting key and the second keyway restricts the rotation of the limiting block relative to the rotating shaft. At the same time, the resistance generated by the first connecting key and the first keyway restricts the rotation of the eccentric wheel relative to the rotating shaft. In addition, the rebound force generated by the compression of the second spring prevents external forces from unintentionally causing the limiting block to slide on the rotating shaft, further preventing external forces from unintentionally moving the sieve plate and causing changes in the cross-section of the screening channel, thereby improving the efficiency and quality of producing coke gemstones.

[0022] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] This utility model provides a vibration screening device for fused gemstones, such as... Figures 1-3As shown, the device includes a base 1 and a screen box 2 movably mounted on the base 1. The screen box 2 is equipped with a vibrator 3, and the base 1 is equipped with a motor 4 that drives the vibrator 3. The screen box 2 has several horizontal support plates 5 that support vertical support plates 6, and several vertical support plates 6 mounted on the horizontal support plates 5. Specifically, the vertical support plates 6 have inclined surfaces to allow the coke to smoothly enter the screening channel 9. A screen plate 7 is slidably connected to the vertical support plate 6, and one side of the screen plate 7 has an inclined surface 8. A screening channel 9 is formed between two adjacent inclined surfaces 8. The cross-section of the screening channel 9 gradually increases from top to bottom. The screen box 2 has several partitions 10 that divide the screening into several collection chambers 11. The bottom of the screen box 2 has several outlets 12 that communicate with the collection chambers 11. After the coke is fed into the screen box 2, the vibrator is driven by the motor 4. 3. The screen box 2 rotates, causing it to vibrate. This causes the charred gemstones on the screen plate 7 to shake and fall, sequentially into the screening channel 9 between the two screen plates 7. Simultaneously, because the cross-section of the screening channel 9 gradually increases from top to bottom, smaller charred gemstones pass through the screening channel 9 first and fall into the uppermost collection chamber 11. As the cross-section of the screening channel 9 changes, the size of the charred gemstones that can pass through the screening channel 9 gradually increases, allowing medium-sized charred gemstones and larger charred gemstones to fall sequentially into their respective collection chambers 11. Then, through their respective discharge ports 12, they enter different subsequent processes, achieving simultaneous screening of charred gemstones of various pore sizes without the need to feed them separately onto screens with different mesh sizes. This improves the efficiency of charred gemstone screening and the efficiency and quality of producing various charred gemstone derivatives. Furthermore, it eliminates the need to manufacture screens with different mesh sizes and associated vibration equipment, thus reducing the cost of producing charred gemstones. In addition, by sliding the sieve plate 7 on the vertical support plate 6, the distance between two adjacent inclined surfaces 8 can be adjusted, thereby adjusting the cross-section of the screening channel 9 to adapt to the screening needs under different conditions in the production of coke gemstones, and further improving the efficiency and quality of coke gemstone production.

[0024] The transverse support plate 5 is provided with several transverse grooves 13, and one side of the sieve plate 7 is provided with several sliding rods 14 that pass through the vertical support plate 6 and slide in contact with the transverse grooves 13. These rods guide the sliding of the sieve plate 7 on the vertical support plate 6, thereby better adjusting the cross-section of the screening channel 9 and further improving the efficiency and quality of producing coke gemstones.

[0025] Preferred, such as Figure 5As shown, the end of the slide rod 14 is provided with a roller 15, and several eccentric wheels 16 are rotatably connected to the transverse support plate 5. The two sides of the eccentric wheels 16 are respectively provided with arc surfaces 17 that contact the rollers 15. A first spring 18 is provided between the screen plate 7 and the vertical support plate 6. When the eccentric wheels 16 are rotated counterclockwise on the transverse support plate 5, the arc surfaces 17 on the side of the eccentric wheels 16 contact the rollers 15, and the resulting force drives the rollers 15 to move to both sides, thereby causing the screen plate 7 to slide inward on the vertical support plate 6. When the eccentric wheels 16 are rotated clockwise on the transverse support plate 5, the arc surfaces 17 on the side of the eccentric wheels 16 do not contact the rollers 15. Under the action of the rebound force of the first spring 18, the transverse support plate 5 is driven to move outward on the vertical support plate 6, thereby realizing the adjustment of the cross-section of the screening channel 9 and further improving the efficiency and quality of producing coke gemstones.

[0026] Preferred, such as Figure 3 , Figure 5 and Figure 6 As shown, the transverse support plate 5 is provided with a rotating shaft 19 rotatably connected to the eccentric wheel 16. One side of the eccentric wheel 16 has several first keyways 20. A limit block 21 is slidably connected to the rotating shaft 19. One side of the limit block 21 has several first connecting keys 22 that slide in contact with the first keyways 20. The limit block 21 has several second connecting keys 23. The rotating shaft 19 has several second keyways 24 that slide in contact with the second connecting keys 23. When the eccentric wheel 16 needs adjustment, the limit block 21 is pulled upwards, causing it to slide on the rotating shaft 19. This allows the second connecting keys 23 on the limit block 21 to slide out of the second keyways 24, thereby releasing the restriction on the rotation of the limit block 21 relative to the rotating shaft 19. Simultaneously, since the first connecting keys 22 are always located within the first keyways 20, the rotation is restricted... When the eccentric wheel 16 is rotated on the rotating shaft 19, the first connecting key 22 contacts the first keyway 20, thereby adjusting the cross-section of the screening channel 9 and further improving the efficiency and quality of producing coke gemstones. After adjustment, the limiting block 21 is pressed down, causing it to slide down on the rotating shaft 19. This allows the second connecting key 23 to return to the second keyway 24. The resistance generated by the contact between the second connecting key 23 and the second keyway 24 restricts the rotation of the limiting block 21 relative to the rotating shaft 19. At the same time, the resistance generated by the first connecting key 22 and the first keyway 20 restricts the rotation of the eccentric wheel 16 relative to the rotating shaft 19. This prevents external forces from unintentionally moving the sieve plate 7, which would cause a change in the cross-section of the screening channel 9, and further improves the efficiency and quality of producing coke gemstones.

[0027] Preferred, such as Figure 3 , Figure 5 and Figure 6As shown, a fixing nut 25 is provided at the end of the rotating shaft 19, and a second spring 26 is provided between the fixing nut 25 and the limiting block 21 to realize the automatic reset of the limiting block 21; in addition, the rebound force generated by the compression of the second spring 26 prevents the external force from unintentionally causing the limiting block 21 to slide on the rotating shaft 19, and further prevents the external force from unintentionally causing the screen plate 7 to move, resulting in a change in the cross-section of the screening channel 9, thereby improving the efficiency and quality of producing coke gemstones.

[0028] Preferred, such as Figure 1 As shown, the vibrator 3 includes a main shaft 27 rotatably mounted on the screen box 2. The main shaft 27 is provided with several eccentric blocks 28. By rotating the main shaft 27 on the screen box 2, the eccentric blocks 28 are driven to rotate on the screen box 2, generating axial excitation force, which causes the screen box 2 to shake on the base 1, and continuously drives the coke stone to move downward.

[0029] Preferred, such as Figure 1 As shown, the motor 4 has a first pulley 29 on its movable end, and a second pulley 30 is rotatably connected to the base 1. It also includes a belt 31 sleeved on the outside of the first pulley 29 and the second pulley 30 to provide power for the rotation of the shaft 19. A coupling 32 is provided between the second pulley 30 and the main shaft 27 to eliminate the eccentricity between the main shaft 27 and the second pulley 30.

[0030] Preferred, such as Figure 1 As shown, several rubber springs 33 and dampers 34 are provided between the screen box 2 and the base 1, so that the screen box 2 vibrates on the base 1 according to the design requirements, while isolating the vibration from external transmission and preventing damage to the foundation and surrounding equipment due to resonance.

[0031] Example 1 This utility model provides a vibration screening device for fused gemstones, such as... Figures 1-3 As shown, after the coke is fed into the screen box 2, the vibrator 3 is driven by the motor 4 to rotate on the screen box 2, causing the screen box 2 to vibrate. This causes the coke on the screen plate 7 to shake and fall, and fall into the screening channel 9 between the two screen plates 7 in sequence. At the same time, since the cross-section of the screening channel 9 gradually increases from top to bottom, the coke with smaller apertures passes through the screening channel 9 first and falls into the uppermost collection chamber 11. As the cross-section of the screening channel 9 changes, the particle size of the coke that can pass through the screening channel 9 gradually increases, allowing medium-sized coke and larger apertures to fall into the corresponding collection chambers 11 in sequence. Then, through the corresponding discharge port 12, they enter different next processes, realizing the simultaneous screening of coke with multiple apertures without having to feed them into screens with different mesh sizes. This improves the efficiency of screening coke and the efficiency and quality of producing various coke derivatives. In addition, there is no need to manufacture screens with different aperture sizes and matching vibration equipment, thereby reducing the cost of producing coke. In addition, by sliding the sieve plate 7 on the vertical support plate 6, the distance between two adjacent inclined surfaces 8 can be adjusted, thereby adjusting the cross-section of the screening channel 9 to adapt to the screening needs under different conditions in the production of coke gemstones, and further improving the efficiency and quality of coke gemstone production.

[0032] Example 2 Based on Example 1, such as Figures 3-6 As shown, when the eccentric wheel 16 needs to be adjusted, the limiting block 21 is pulled upward, causing the limiting block 21 to slide on the rotating shaft 19, allowing the second connecting key 23 on the limiting block 21 to slide out from the second keyway 24, thereby releasing the restriction on the rotation of the limiting block 21 relative to the rotating shaft 19. At the same time, since the first connecting key 22 is always located in the first keyway 20, when the limiting block 21 is rotated, the first connecting key 22 contacts the first keyway 20, causing the eccentric wheel 16 to rotate on the rotating shaft 19. When the eccentric wheel 16 is rotated counterclockwise on the transverse support plate 5, the arc surface 17 on the side of the eccentric wheel 16 contacts the roller 15, and the resulting force drives the roller 15 to move to both sides, thereby causing the screen plate 7 to slide inward on the vertical support plate 6. When the eccentric wheel 16 is rotated clockwise on the transverse support plate 5, the arc surface 17 on the side of the eccentric wheel 16 does not contact the roller 15. Under the action of the rebound force of the first spring 18, the transverse support plate 5 is driven to move outward on the vertical support plate 6, thereby realizing the adjustment of the cross-section of the screening channel 9 and further improving the efficiency and quality of producing coke gemstones. After adjustment, the rebound force generated by the compression of the second spring 26 causes the limiting block 21 to slide downward on the rotating shaft 19, so that the second connecting key 23 returns to the second keyway 24. The resistance generated by the contact between the second connecting key 23 and the second keyway 24 restricts the rotation of the limiting block 21 relative to the rotating shaft 19. At the same time, the resistance generated by the first connecting key 22 and the first keyway 20 restricts the rotation of the eccentric wheel 16 relative to the rotating shaft 19. In addition, the rebound force generated by the compression of the second spring 26 prevents the limiting block 21 from sliding on the rotating shaft 19 unintentionally by external force, and further prevents the screen plate 7 from moving unintentionally by external force, which would cause the cross-section of the screening channel 9 to change, thereby improving the efficiency and quality of producing coke gemstones.
