Description

Technical Field

[0001] This invention relates to the field of refractory material recycling technology, specifically to a raw material recycling and dust suppression mechanism for refractory materials. Background Technology

[0002] The raw materials for refractory materials mainly include corundum and silicon carbide. A large amount of waste is generated during their production and processing. During the recycling of this waste, a significant amount of dust is generated due to collisions between materials and between materials and equipment. To ensure a clean environment in the production workshop, dust suppression mechanisms are needed to control the dust. For example, a dust suppression device for refractory material production, with announcement number CN223010150U, includes a dust collection box. An inclined guide plate is fixed inside the dust collection box, and a hollow gas distribution plate is fixed below the guide plate. The suction end of a high-pressure air pump is connected to the hollow gas distribution plate. The internal cavity is connected, the exhaust end of the high-pressure air pump passes through the guide plate and extends upward. A spray assembly is suspended above the exhaust hood. A drain pipe is fixed on one side of the dust collector. When the high-pressure air pump is started, air can be drawn from different directions of the dust collector through multiple suction heads to expand the suction range of the dust collector. Through multiple connecting hoses, the dust gas can first be collected into the hollow air distribution plate, and then drawn into the exhaust hood together. The spray assembly can treat the dust gas entering the exhaust hood by dust suppression. The dust wastewater flows along the guide plate to the drain pipe. The structure is simple and the dust removal efficiency is high. For example, a dust suppression device for refractory material preparation, with announcement number CN218249175U, includes casters, a shock-absorbing mechanism, an external suction mechanism, a supporting discharge mechanism, and an internal dust-suppressing mechanism. Four casters are located below the shock-absorbing mechanism, the supporting discharge mechanism is located above it, the external suction mechanism is located above the supporting discharge mechanism, and the internal dust-suppressing mechanism is located inside the supporting discharge mechanism. The supporting discharge mechanism collects and discharges dust, while the external suction mechanism and internal dust-suppressing mechanism absorb the dust. The shock-absorbing mechanism dampens the vibrations generated by the supporting discharge mechanism, effectively absorbing and collecting refractory material dust and allowing for recycling, thus reducing resource waste. However, the above-mentioned dust suppression device still has the following drawbacks in actual use: 1. Traditional dust suppression mechanisms have their dust inlets set in fixed positions, making it difficult to adapt to changes in dust under different working conditions. When recovering raw materials for refractory materials, changes in operating height can cause the dust to drift, resulting in a decrease in the adsorption efficiency of existing fixed dust suppression systems. 2. Most existing dust suppression mechanisms have built-in dust filter bags to intercept dust, but cleaning the filter components relies on manual operation or additional drive mechanisms, resulting in low automation and high energy consumption.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on existing dust suppression mechanisms. Summary of the Invention

[0004] The purpose of this invention is to provide a dust suppression mechanism for the recovery of raw materials for refractory materials, in order to solve the problems mentioned in the background art, where the dust suction port of the traditional dust suppression mechanism is mostly set in a fixed position, making it difficult to adapt to changes in dust under different working conditions, and the cleaning of the filter components depends on manual operation or an additional drive mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a raw material recovery and dust suppression mechanism for refractory materials, comprising a dust collection box, a movable box being movably disposed on the top of the dust collection box, and a first dust suppression mechanism being disposed inside the movable box, wherein the first dust suppression mechanism is used to absorb dust from the space above. It also includes: a second dust collection mechanism, which is located at the bottom of the dust collection box. The second dust collection mechanism is used to absorb dust in the space below. A partition plate is fixed to the inner wall of the dust collection box, and a dust filter mechanism is provided below the partition plate. The dust filter mechanism is used to intercept the absorbed dust.

[0006] Preferably, the first dust collection mechanism includes a movable box rotatably disposed on the top of the dust collection box, and a cross-shaped first dust inlet pipe runs through the interior of the movable box. Tooth blocks are fixed at equal angles at the edges of the movable box, and a first gear is meshed with the sides of the tooth blocks.

[0007] Preferably, the first gear is driven by a motor, and both the movable box and the outer side of the first gear are fitted with protective boxes, and the protective boxes and the movable box are rotatably connected. At the same time, the upper end face of the protective box is fixedly installed by a hanging rod.

[0008] Preferably, the dust filtration mechanism includes a fixed tube that is fixedly inserted through the partition plate, and the bottom of the fixed tube and the first dust inlet tube are rotatably connected. A support plate is fixedly sleeved on the bottom of the fixed tube, and a dust removal bag is attached to the lower end face of the support plate.

[0009] Preferably, a toothed ring is fixedly sleeved at the lower end of the fixed tube, and the toothed ring and the second gear are meshed together. The second gear is rotatably mounted on the support plate and is driven by another motor.

[0010] Preferably, the upper end of the toothed ring is fixedly connected to one end of the traction rope, and the other end of the traction rope is fixed to the top of the movable strip, and the movable strip extends through the top of the support plate.

[0011] Preferably, the movable strip and the fixed rod are elastically slidably connected, and the movable strip and the fixed rod are distributed at equal angles, and the inner side of the movable strip is in close contact with the outer wall of the dust collection bag.

[0012] Preferably, the second dust suppression mechanism includes a connecting rod disposed on the side of the movable box, one end of the connecting rod being slidably connected to the movable box, and a sleeve tube being fixedly connected to the bottom of the connecting rod.

[0013] Preferably, the sleeve is fitted onto the bottom of the second dust inlet pipe, the sleeve and the second dust inlet pipe are slidably connected, and the second dust inlet pipe is fixedly inserted through the side of the movable ring plate, and the movable ring plate is rotatably fitted onto the outside of the dust collector box. At the same time, the top of the second dust inlet pipe and the fixed pipe are rotatably connected, and the second dust inlet pipe penetrates through the side wall of the dust collector box.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the raw material recovery and dust suppression mechanism for refractory materials, by setting multiple sets of dust suction structures, can remove flying dust and falling dust. Furthermore, the dust suction structure, through rotation and lifting, can expand the dust suction range, improve the cleanliness of the workshop environment, and can also automatically clean the dust in the filter bag, preventing it from sticking and affecting air exhaust. The specific details are as follows: 1. Through the meshing transmission of the first gear and the tooth block, the movable box is driven to rotate on the top of the dust collection box, so that the movable box can drive the first dust inlet pipe to rotate, realizing all-round dust collection; 2. When the movable box rotates, it drives the movable ring plate to rotate synchronously via the connecting rod, which in turn drives the second dust inlet pipe to rotate, achieving omnidirectional dust suction; Furthermore, when the connecting rod rotates, it causes the support rod to contact the guide groove. The guide groove guides the connecting rod to slide on the movable box and causes the sleeve tube to rise and fall on the second dust inlet pipe. Therefore, while the sleeve tube rotates, it can also increase the dust collection range by rising and falling. 3. The second gear drives the gear ring to rotate, which in turn pulls the traction rope. This allows the upper end of the gear ring to wind up the traction rope, pulling the movable strip to slide on the fixed rod. When the motor drives in the reverse direction, the gear ring releases the pull on the traction rope, and the spring's elasticity causes the movable strip to move in the opposite direction. Therefore, the movable strips, which are evenly distributed, can move closer and further apart simultaneously. During the movement, the dust bag contracts and expands, which shakes off the dust adhering to its inner wall, facilitating subsequent cleaning. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1-9 The present invention provides the following technical solution: Example 1: To address the problems existing in the prior art, this example provides a dust collection and recovery mechanism for refractory materials, comprising a dust collection box 1, a movable box 2 movably mounted on the top of the dust collection box 1, and the bottom of the dust collection box 1 being stably supported on the ground by support legs. The top of the protective box 6 is suspended by a hanging rod 7 to ensure that the movable box 2 can rotate stably. A first dust collection mechanism is provided inside the movable box 2 to absorb dust from the space above. The system also includes a second dust collection mechanism located at the bottom of the dust collection box 1 to absorb dust from the space below. A partition plate 9 is fixed to the inner wall of the dust collection box 1, and a dust filter mechanism is provided below the partition plate 9 to intercept the absorbed dust.

[0019] Existing dust suppression systems typically have their suction inlets fixed in place, making it difficult to adapt to varying dust conditions. When recovering raw materials for refractory materials, changes in operating height can cause a shift in the location of dust dispersion, leading to a decrease in the adsorption efficiency of existing fixed dust suppression systems. Figures 1-3As shown, the first dust removal mechanism includes a movable box 2 rotatably mounted on the top of the dust collection box 1. A cross-shaped first dust inlet pipe 3 runs through the interior of the movable box 2. Tooth blocks 4 are fixed at equal angles on the edge of the movable box 2, and a first gear 5 is meshed with the side of the tooth blocks 4. The first gear 5 is driven by a motor, and protective boxes 6 are fitted on the outside of both the movable box 2 and the first gear 5. The protective boxes 6 and the movable box 2 are rotatably connected, and the upper end of the protective box 6 is fixedly installed by a hanging rod 7. First, the device is pushed to the designated position. When dust removal is needed, the suction fan in the dust collection box 1 runs, sucking the external dust into the dust collection box 1 through the first dust inlet pipe 3, thus completing the dust removal of the upper space. When suctioning, the motor drives the first gear 5 to rotate. Through the meshing transmission between the first gear 5 and the tooth blocks 4, the movable box 2 rotates on the top of the dust collection box 1. In this way, the movable box 2 can drive the first dust inlet pipe 3 to rotate, achieving all-round dust suction. When the first dust inlet pipe 3 rotates, it can rotate on the top of the fixed pipe 8, so it does not affect the entry of dust.

[0020] Example 2: Most existing dust suppression mechanisms have built-in dust filter bags to intercept dust, but cleaning the filter components relies on manual operation or additional drive mechanisms, resulting in low automation and high energy consumption. Therefore, this example uses the following technical solution, such as... Figures 6-8As shown, the dust filtration mechanism includes a fixed pipe 8 that is fixedly inserted through the partition plate 9, and the bottom of the fixed pipe 8 and the first dust inlet pipe 3 are rotatably connected. A support plate 10 is fixedly fitted onto the bottom of the fixed pipe 8, and a dust collection bag 11 is attached to the lower end of the support plate 10. A toothed ring 13 is fixedly fitted onto the lower end of the fixed pipe 8, and the toothed ring 13 and a second gear 12 are meshed together. The second gear 12 is rotatably mounted on the support plate 10 and is driven by another motor. The upper end of the toothed ring 13 is fixedly connected to one end of a traction rope 14, and the other end of the traction rope 14 is fixed to the top of a movable strip 15. The movable strip 15 movably passes through the top of the support plate 10. The movable strip 15 and the fixed rod 16 are elastically slidably connected, and both the movable strip 15 and the fixed rod 16 are equidistantly distributed. The inner side of the dust collector is attached to the outer wall of the dust collector bag 11. The dust sucked into the dust collector box 1 can be transferred to the dust collector bag 11 through the fixed pipe 8, so that the dust is intercepted by the dust collector bag 11 and the gas is discharged. At the same time, another motor drives the second gear 12 to rotate, and the second gear 12 drives the gear ring 13 to rotate, which in turn pulls the traction rope 14. In this way, the upper end of the gear ring 13 can wind up the traction rope 14, pulling the movable strip 15 to slide on the fixed rod 16. When the motor drives in the opposite direction, the gear ring 13 releases the pull on the traction rope 14, and the elasticity of the spring drives the movable strip 15 to move in the opposite direction. Therefore, the movable strips 15, which are distributed at equal angles, can move closer and further away at the same time. During the movement, the dust collector bag 11 is contracted and expanded, which can shake off the dust adhering to its inner wall, ensure smooth gas flow, and facilitate subsequent dust cleaning.

[0021] Example 3: Most existing dust collection mechanisms are relatively simple, only able to remove dust from the same location or height. Therefore, this example uses the following technical solution, such as... Figure 2 and Figures 4-5 As shown, the second dust collection mechanism includes a connecting rod 17 disposed on the side of the movable box 2, with one end of the connecting rod 17 slidably connected to the movable box 2, and a sleeve tube 18 fixedly connected to the bottom of the connecting rod 17; the sleeve tube 18 is sleeved on the bottom of the second dust inlet pipe 19, and the sleeve tube 18 and the second dust inlet pipe 19 are slidably connected, with the second dust inlet pipe 19 fixedly penetrating the side of the movable ring plate 20, and the movable ring plate 20 rotatably sleeved on the outside of the dust collection box 1, while the top of the second dust inlet pipe 19 and the fixed pipe 8 are rotatably connected, as shown. Figure 6As shown, the end of the second dust inlet pipe 19 is rotatably sleeved on the outside of the fixed pipe 8 through a sleeve, so that it does not affect the rotation of the second dust inlet pipe 19 or the gas transmission. The second dust inlet pipe 19 passes through the side wall of the dust collector 1; a support rod 21 is fixed to the side of the connecting rod 17, and the end of the support rod 21 away from the connecting rod 17 is slidably disposed inside the guide groove 23, and the guide groove 23 has a wavy structure. At the same time, the guide groove 23 is opened on the outside of the fixed ring plate 22, and the fixed ring plate 22 is fixed to the outside of the dust collector 1; while vacuuming, the second dust inlet pipe 19 is rotatably sleeved on the outside of the fixed pipe 8 through a sleeve, so that it does not affect the rotation of the second dust inlet pipe 19 or the gas transmission. The second dust inlet pipe 19 can suck the dust from the lower part into the dust collection box 1. When the movable box 2 rotates, it drives the movable ring plate 20 to rotate synchronously through the connecting rod 17, and at the same time drives the second dust inlet pipe 19 to rotate to achieve all-round dust collection. When the connecting rod 17 rotates, it drives the support rod 21 to contact the guide groove 23. Through the guidance of the guide groove 23, the support rod 21 can be guided to slide on the movable box 2, and drive the sleeve tube 18 to rise and fall on the second dust inlet pipe 19. Therefore, while the sleeve tube 18 is rotating, it can also increase the dust collection range by rising and falling.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
