Description

Technical Field

[0001] The utility model relates to the technical field of vibration drying beds, and particularly relates to a drying and screening device for carbide slag and fly ash. Background Technique

[0002] The fluidized bed dryer is an efficient drying equipment, which is widely used in industries such as chemical engineering, pharmacy, food, and minerals. Its working principle is based on the fluidized bed technology, that is, by suspending solid particles in the upward airflow to form a flowing state similar to that of a liquid, so as to achieve efficient heat transfer and material drying, and can uniformly dry a variety of objects, such as carbide slag and fly ash, etc.;

[0003] As shown in the reference case "A Vibration Fluidized Bed Dryer" with the publication number "CN213631192U", it is a vibration fluidized bed dryer. A vibration motor is added outside its lower box body, so that the required amount of air can be reduced. In addition, by controlling the output power of the vibration motor, the drying time of the material in the box can also be adjusted;

[0004] When the existing vibration drying bed vibrates, in order to improve efficiency, a screening plate is usually installed inside to screen the material at the same time. However, during drying and screening, due to the initial humidity of the material, particles with higher humidity are easily adhered to the sieve holes to form blockages, thereby reducing the rate of material passing through the screening plate, resulting in too long residence time of the material in the drying bed and overall drying efficiency.

[0005] Therefore, a drying and screening device for carbide slag and fly ash is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a drying and screening device for carbide slag and fly ash to solve the above problems, improving the problem that when the existing vibration drying bed vibrates, in order to improve efficiency, a screening plate is usually installed inside to screen the material at the same time. However, during drying and screening, due to the initial humidity of the material, particles with higher humidity are easily adhered to the sieve holes to form blockages, thereby reducing the rate of material passing through the screening plate, resulting in too long residence time of the material in the drying bed and overall drying efficiency.

[0007] The present utility model achieves the above object through the following technical solutions. A carbide slag fly ash drying and screening device includes: a support frame, a drying box is slidably installed on the top of the support frame, a plurality of vibrators are fixedly installed at the bottom of the support frame, one side of each of the plurality of vibrators is fixedly connected to the drying box, two screening plates are fixedly installed inside the drying box, a dredging and collecting mechanism for dredging and cleaning the screening plates is arranged on one side of the screening plates. Among them, the dredging and collecting mechanism includes an electric slide rail fixedly installed on one side of the drying box, a dredging component is arranged on one side of the electric slide rail, and a collecting component is arranged on the outer side of the drying box. When pouring materials such as carbide slag or fly ash that need to be dried into the drying box, the vibrators continuously vibrate the drying box to achieve vibratory drying, and the materials can be screened by the screening plates during vibration. When screening, the dredging component can continuously dredge and clean the sieve holes of the screening plates while screening to ensure that the sieve holes are always unobstructed, thereby maintaining the screening efficiency and the normal operation of the drying box. The collecting component can conveniently collect the dried materials and the cleaned impurities separately.

[0008] Preferably, the dredging component includes a movable plate slidably installed inside the drying box. One side of the movable plate is fixedly connected to the electric slide rail.

When dredging, the electric slide rail drives the movable plate to continuously move back and forth between the two screening plates, and the driving plates move accordingly, so that the plurality of cleaning heads fixed on the driving plates pass through the sieve holes of the screening plates for cleaning. These cleaning heads effectively remove the blockages in the sieve holes, such as adhered carbide slag and fly ash particles, by physical contact, keeping the sieve holes unobstructed. The fixed installation between the plurality of springs provides the necessary pressure and elasticity for the cleaning heads to ensure that the cleaning heads can stably clean the blockages.

When the cleaning heads clean the blockages inside the sieve holes, the trumpet-shaped sieve holes can separate the blockages from the sieve holes when the cleaning heads slightly enter the sieve holes, making the cleaning more convenient. The limiting plate can limit the entry distance of the cleaning heads to prevent the cleaning heads from entering the sieve holes too deeply.

[0010] Preferably, two guide rods are fixedly installed on one side of the driving plate. One end of each guide rod penetrates through the movable plate and is fixedly connected to the support plate.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-4 shown, a calcium carbide slag fly ash drying and screening device includes: a support frame 1, a drying oven 11 is slidably installed on the top of the support frame 1, a plurality of vibrators 12 are fixedly installed at the bottom of the support frame 1, one side of each of the plurality of vibrators 12 is fixedly connected to the drying oven 11, two screening plates 13 are fixedly installed in the drying oven 11, and a dredging and collection mechanism 3 for dredging and cleaning the screening plate 13 is arranged on one side of the screening plate 13. Among them, the dredging and collection mechanism 3 includes an electric slide rail 31 fixedly installed on one side of the drying oven 11, a dredging component 32 is arranged on one side of the electric slide rail 31, and a collection component 33 is arranged outside the drying oven 11. When pouring materials such as calcium carbide slag or fly ash that need to be dried into the drying oven 11, the drying oven 11 is continuously vibrated by the vibrator 12 to realize vibration drying, and the materials can be screened by the screening plate 13 during vibration. When screening, the dredging component 32 can continuously dredge and clean the screening holes of the screening plate 13 while screening to ensure that the screening holes are always unobstructed, so as to maintain the screening efficiency and the normal operation of the drying oven 11. The collection component 33 can conveniently collect the dried materials and the cleaned impurities separately.

[0024] As Figure 2 and Figure 3As shown in the figure, the dredging component 32 includes a movable plate 321 slidably installed inside the drying box 11. One side of the movable plate 321 is fixedly connected to the electric slide rail 31. The movable plate 321 has a hollow structure inside. Two support plates 322 are slidably installed inside the movable plate 321. A plurality of springs 323 are fixedly installed between the two support plates 322. On the sides of the two support plates 322 away from each other, there are drive plates 324. The two drive plates 324 are respectively located on one side of the two screening plates 13. A plurality of cleaning heads 325 are fixedly installed on the surface of the drive plate 324. One side of each of the plurality of cleaning heads 325 extends into the sieve holes of the adjacent screening plate 13. When dredging, the electric slide rail 31 drives the movable plate 321 to continuously move back and forth between the two screening plates 13, and the drive plate 324 moves accordingly, so that the plurality of cleaning heads 325 fixed on the drive plate 324 pass through the sieve holes of the screening plate 13 for cleaning. Through physical contact, these cleaning heads 325 effectively remove the blockages in the sieve holes, such as adhered carbide slag and fly ash particles, and keep the sieve holes unobstructed. The fixed installation between the plurality of springs 323 provides the necessary pressure and elasticity for the cleaning heads 325, ensuring that the cleaning heads 325 can stably clean the blockages. The sieve holes of the screening plate 13 are set in a horn shape, and one side of the cleaning head 325 is set in a semi-circular shape. A same limiting plate 326 is fixedly installed on the outside of the plurality of cleaning heads 325 on the same side. The limiting plate 326 is in contact with the surface of the adjacent screening plate 13. The two screening plates 13 are arranged staggeredly, and the sieve holes of the two screening plates 13 are mirror-symmetrically arranged. When the cleaning head 325 cleans the blockages inside the sieve holes, through the horn-shaped sieve holes, the blockages can be separated from the sieve holes when the cleaning head 325 slightly enters the sieve holes, making the cleaning more convenient. The limiting plate 326 can limit the entry distance of the cleaning head 325 to prevent the cleaning head 325 from penetrating too deep into the sieve holes. Two guide rods 327 are fixedly installed on one side of the drive plate 324. One end of the guide rod 327 penetrates through the movable plate 321 and is fixedly connected to the support plate 322. When the drive plate 324 moves, it can be limited and guided by the two guide rods 327, making the support plate 322 more stable when moving the drive plate 324. A drying fan 2 is fixedly installed on one side of the support frame 1. A wind guide plate 21 is fixedly installed on the top of the drying box 11. The drying fan 2 is connected to the wind guide plate 21. When drying, the drying hot air can be evenly poured into the drying box 11 through the cooperation of the wind guide plate 21 and the drying fan 2 to dry the materials.

An inlet plate 333 is provided on one side of the first collection box 331. One side of the inlet plate 333 is connected to the drying box 11. An inlet pipe 334 is fixedly installed on one side of the second collection box 332. The inlet pipe 334 is communicated with the inside of the drying box 11. The dried material can be guided by the two screening plates 13 and enter the inside of the first collection box 331 for collection. Smaller impurities and dust can fall onto the inner bottom wall of the drying box 11 and be conveniently collected into the second collection box 332 through the inlet pipe 334. The collection component 33 further includes a telescopic pipe 335 fixedly installed on the surface of the inlet pipe 334. The inlet plate 333 is arranged in an L shape, and one side of the inlet plate 333 is slidably connected to the top of the first collection box 331. When the second collection box 332 is connected to the drying box 11 through the inlet pipe 334, the telescopic pipe 335 can be deformed synchronously to adapt when the drying box 11 vibrates, so that the inlet pipe 334 is stably connected to the drying box 11. The inlet plate 333 can be stably connected to the first collection box 331 through continuous sliding.

[0026] When the present utility model is in use and during dredging, the electric slide rail 31 drives the movable plate 321 to continuously move back and forth between the two screening plates 13. The driving plate 324 moves accordingly, so that a plurality of cleaning heads 325 fixed on the driving plate 324 pass through the sieve holes of the screening plates 13 for cleaning. These cleaning heads 325 effectively remove the blockages in the sieve holes, such as adhered calcium carbide slag and fly ash particles, through physical contact, keeping the sieve holes unobstructed. The fixed installation between the plurality of springs 323 provides the necessary pressure and elasticity for the cleaning heads 325, ensuring that the cleaning heads 325 can stably clean the blockages. The two screening plates 13 are arranged in an alternating manner, and the sieve holes of the two screening plates 13 are mirror-symmetrically arranged. When the cleaning heads 325 clean the blockages inside the sieve holes, the blockages can be separated from the sieve holes when the cleaning heads 325 slightly enter the sieve holes through the trumpet-shaped sieve holes, making the cleaning more convenient. The limiting plate 326 can limit the entering distance of the cleaning heads 325 to prevent the cleaning heads 325 from entering the sieve holes too deeply. The dried material can be guided by the two screening plates 13 and enter the inside of the first collection box 331 for collection. Smaller impurities and dust can fall onto the inner bottom wall of the drying box 11 and be conveniently collected into the second collection box 332 through the inlet pipe 334. When the second collection box 332 is connected to the drying box 11 through the inlet pipe 334, the telescopic pipe 335 can be deformed synchronously to adapt when the drying box 11 vibrates, so that the inlet pipe 334 is stably connected to the drying box 11. The inlet plate 333 can be stably connected to the first collection box 331 through continuous sliding.
