Description

Technical Field

[0001] The utility model belongs to the technical field of solid waste resource treatment and processing, and particularly relates to a sorting and impurity removing device for waste refractory materials. Background Technique

[0002] During the use of existing high-temperature industrial equipment, a relatively large amount of waste refractory materials are generated every year. Waste refractory materials are a kind of industrial waste with a large quantity, extremely difficult to handle, and extremely unfriendly to the environment, having problems of difficult treatment and environmental pollution. With the increasing depletion of natural resources and the increasing amount of waste refractory materials, the resource recycling and reuse of waste refractory materials has also become a current energy-saving and emission-reduction disposal measure. After several years of technical research and development, the production process of using waste refractory materials as raw materials to produce high-quality refractory bricks mainly includes raw material pretreatment, batching, mixing, mulling, forming, firing, etc. Since the recycled waste refractory materials are mixed with impurities such as metals and plastics, the raw material pretreatment is mainly to crush, sort and remove impurities from the recycled waste refractory materials to reduce the impurity content rate of the waste refractory materials. In the existing technology, the sorting and impurity removing device for waste and refractory materials mainly sets a feeding cone above the multi-layer sorting sieve plates, and a magnet is arranged on the feeding cone. When in use, after the waste refractory materials pass through the powder cone, the magnet can perform magnetic separation on the waste refractory materials to separate the metal impurities in the waste refractory materials. However, this device has the following deficiencies during use: First, the waste refractory materials are subjected to impurity removal treatment through the powder cone. Since the falling speed of the waste refractory materials is relatively fast, the magnet cannot perform comprehensive magnetic absorption on the waste refractory materials, and the impurity removal effect is very poor; Second, the existing sorting sieve plates use a vibration mechanism to generate vibration to achieve sorting. The vibration amplitude of the vibration mechanism is relatively large, not only generating a large amount of noise, but also seriously affecting the service life of the device due to the large vibration amplitude. Therefore, it is objectively necessary to develop a sorting and impurity removing device for waste refractory materials with reasonable structure, remarkable sorting and impurity removing effect, and durability. Summary of the Invention

[0003] The purpose of the utility model is to provide a sorting and impurity removing device for waste refractory materials with reasonable structure, remarkable sorting and impurity removing effect, and durability.

[0004] The object of the present utility model is achieved as follows. It includes a feed inlet and a sorting box. An intermediate partition is inclinedly arranged in the sorting box. A impurity removal mechanism is arranged in the sorting box above the intermediate partition. A blanking hopper is arranged at the higher end of the intermediate partition. A waste material outlet is arranged on the sorting box at the upper side of the lower end of the intermediate partition. 2 to 3 layers of sorting mechanisms are arranged in the sorting box below the intermediate partition. The sorting mechanism includes a sorting plate and a lifting drive. The lifting drives are symmetrically installed on both sides of the inner wall of the sorting box. The sorting plate is installed above the lifting drive. A plurality of sorting holes are processed on the sorting plate. The apertures of the sorting holes on the multi-layer sorting plates decrease successively from top to bottom. Material outlets are correspondingly arranged on the sorting box above each layer of sorting mechanism, and a discharge port is arranged at the bottom of the sorting box.

[0005] Compared with the existing technology, the advantages of this device are as follows: An intermediate partition is arranged in the sorting box, and the impurity removal mechanism is arranged above the intermediate partition. During the process of conveying the waste refractory materials by the impurity removal mechanism, magnetic separation and impurity removal treatment can be carried out on the waste refractory materials, separating the magnetic metal materials in the waste refractory materials. The arranged impurity removal mechanism can extend the contact time with the waste refractory materials, ensuring the thoroughness and high efficiency of the magnetic separation of the waste refractory materials. Second, the lifting drive is used to drive the sorting plate to vibrate up and down to achieve the sorting of the waste refractory materials. The lifting drive drives the sorting plate to vibrate up and down, with a small vibration amplitude and low noise. It can solve the problems of small noise and large vibration while achieving high-efficiency sorting, effectively extending the service life of the equipment and the usage time of the equipment. It has the characteristics of simple structure, good sorting and impurity removal effect, and durability, and is easy to promote and use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0009] The following further describes the present utility model in conjunction with the accompanying drawings, but does not limit the present utility model in any way. Any changes or improvements made based on the teachings of the present utility model fall within the protection scope of the present utility model.

[0010] As Figures 1-2 shown, the present utility model includes a feed inlet 1 and a sorting box 2. An intermediate partition 3 is inclined in the sorting box 2. A impurity removal mechanism is arranged in the sorting box 2 above the intermediate partition 3. A blanking hopper 4 is arranged at the higher end of the intermediate partition 3. A waste material outlet 5 is arranged on the sorting box 2 above the lower end of the intermediate partition 3. 2 to 3 layers of sorting mechanisms are arranged in the sorting box 2 below the intermediate partition 3. The sorting mechanism includes a sorting plate 6 and a lifting driver. The lifting drivers are symmetrically installed on both sides of the inner wall of the sorting box 2. The sorting plate 6 is installed above the lifting driver. A plurality of sorting holes are processed on the sorting plate 6. The aperture of the sorting holes on the multi-layer sorting plates 6 decreases sequentially from top to bottom. A material outlet 7 is correspondingly arranged on the sorting box 2 above each layer of sorting mechanism. A discharge port 8 is arranged at the bottom of the sorting box 2.

[0011] The working process of this device is as follows: The recycled waste refractory materials enter the sorting box 2 through the feed inlet 1. The impurity removal mechanism can convey the waste refractory materials. During the conveying process, the impurity removal mechanism can perform magnetic separation on the magnetic metals in the waste refractory materials. The magnetic metals separated by magnetic separation are discharged through the waste material outlet 5. The waste refractory materials enter the top-layer sorting mechanism through the blanking hopper 4. The top-layer lifting driver drives the sorting plate 6 to vibrate up and down. During the up-and-down vibration process, the top-layer sorting plate 6 can perform the first sorting on the waste refractory materials. The large-particle waste refractory materials sorted out are discharged from the top-layer material outlet 7. The waste refractory materials with relatively finer particle sizes fall onto the next-layer sorting plate 6 and are sorted again according to the above sorting method until the waste refractory materials with finer particle sizes fall from the bottom-layer sorting plate 6 and are finally discharged from the discharge port 8. The impurity removal mechanism provided in this device can extend the contact time with the waste refractory materials, ensuring the thoroughness and high efficiency of the magnetic separation of the waste refractory materials; at the same time, the lifting driver is used to drive the sorting plate 6 to vibrate up and down to achieve the sorting of the waste refractory materials. The lifting driver drives the sorting plate 6 to vibrate up and down with a small amplitude and low noise, which can solve the problems of high noise and large vibration while achieving high-efficiency sorting, and can effectively extend the service life of the equipment.

[0012] Further, the impurity removal mechanism includes a driving magnetic roller 9, an intermediate roller 10 and a driven roller 11. The driving magnetic roller 9 adopts the structure used in the prior art. The driving magnetic roller 9 mainly includes a roller shaft, an inner shaft sleeve and an outer shaft sleeve arranged coaxially. Sealing plates are detachably installed at both ends of the inner shaft sleeve and the outer shaft sleeve. A number of series of permanent magnets are installed between the inner shaft sleeve and the outer shaft sleeve. The driving magnetic roller 9 of this structure can not only make the roller shaft rotate stably without shaking, that is, the permanent magnets will not shake and their magnetism can play a role. The driving magnetic roller 9 and the driven roller 11 are symmetrically installed at intervals in the sorting box 2. The intermediate roller 10 is installed in the sorting box 2 under the middle of the driving magnetic roller 9 and the driven roller 11. A conveyor belt 12 is wound around the driving magnetic roller 9, the intermediate roller 10 and the driven roller 11. One end of the driving magnetic roller 9 is installed with a driving motor, and the driving motor is not drawn. The driving motor is a prior art, and it can be directly purchased as a finished product according to the power used. Iron-absorbing plates 13 are installed up and down in the conveyor belt 12 on the side close to the driving magnetic roller 9. The iron-absorbing plates 13 are fixedly installed on the inner wall of the sorting box 2 and are in movable contact with the surface of the conveyor belt 12. The feed inlet 1 is arranged at the top of the sorting box 2 on the side close to the driven roller 11. The iron-absorbing plates 13 can adopt neodymium iron boron magnets used in the prior art. During use, the waste refractory materials fall onto the surface of the conveyor belt 12 from the feed inlet 1. During the movement of the conveyor belt 12, the upper iron-absorbing plates 13 can adsorb the magnetic metals in the waste refractory materials on the upper surface of the conveyor belt 12. Then the conveyor belt 12 transports the waste refractory materials and the magnetic metals to the driving magnetic roller 11. Under the adsorption of the driving magnetic roller 11 and the lower iron-absorbing plates 13, the magnetic metals continue to move with the conveyor belt 12 to a non-magnetic position. After the magnetic metals lose the adsorption of the iron-absorbing plates 13, they fall into the blanking hopper 4, while the waste refractory materials fall from the discharge end of the conveyor belt 12 onto the intermediate partition 3 and finally are discharged from the miscellaneous material outlet 5.

[0013] Further, in order to improve the impurity removal effect of the impurity removal mechanism and ensure the uniform feeding amount of the waste refractory materials falling onto the conveyor belt 12, a guide cone 14 extending into the sorting box 2 is arranged at the lower end of the feed inlet 1. The guide cone 14 is a conical structure with a large upper end and a small lower end. A material leveling roller 15 is rotatably installed at the bottom conical opening of the guide cone 14. A plurality of material leveling plates are uniformly arranged on the outer wall of the material leveling roller 15 along its axial direction. A power mechanism for driving its rotation is installed at the end of the material leveling roller 15. The material leveling roller 15 is driven to rotate by the power mechanism. That is, the rotating material leveling plates can evenly discharge the waste refractory materials onto the conveyor belt 12, realizing the uniform feeding of the waste refractory materials, eliminating the need for manual quantitative feeding and effectively reducing the labor intensity.

[0014] Further, a material raking mechanism 16 is provided above the conveyor belt 12 on the side close to the driven roller 11. The material raking mechanism 16 includes a lifting cylinder and a positioning plate. The lifting cylinder is a structure used in the prior art, and finished products can be directly purchased according to the used stroke and pressure. The cylinder block of the lifting cylinder is installed on the top inside the sorting box 2, and the positioning plate is installed on the piston rod of the lifting cylinder. A plurality of material raking teeth are evenly arranged at the bottom of the positioning plate. During use, the lifting cylinder drives the positioning plate to move downward, so that the material raking teeth contact the waste refractory materials on the conveyor belt 12. During the process of the waste refractory materials moving with the conveyor belt 12, the material raking teeth can level the waste refractory materials, improving the effect of magnetic separation and impurity removal of the waste refractory materials.

[0015] Further, the jacking driver includes a protective housing 17, a support rod 18, a toothed plate 19 and a movable slider 20. The protective housing 17 is fixedly installed on the inner wall of the sorting box 2. The support rod 18 is vertically installed on one side inside the protective housing 17. An activity through hole is provided at the top of the protective housing 17. The toothed plate 19 passes through the through hole. The upper end of the toothed plate 19 is connected to the bottom of the sorting plate 6. The lower end of the toothed plate 19 is located inside the protective housing 17 and then contacts one end of the movable slider 20. The other end of the movable slider 20 is slidably installed on the support rod 18. Springs 21 are provided on the support rod 18 on the upper side and the lower side of the movable slider 20. A first motor 22 is installed inside the protective housing 17. The first motor 22 is a structure used in the prior art, and finished products can be directly purchased according to the used power. A turntable is installed on the output shaft of the first motor 22. A half gear 23 is coaxially installed on the turntable. The half gear 23 meshes with the toothed plate 19. During use, the turntable is driven to rotate by the first motor 22, and the half gear 23 rotates synchronously therewith. When the tooth part on the half gear 23 meshes with the toothed plate 19, it will drive the toothed plate 19 to rise. Then, when the half gear 23 rotates and the tooth part disengages from the toothed plate 19, the toothed plate 19 will reset downward due to the loss of driving force. The toothed plate 19 repeatedly rises and falls, enabling the sorting plate 6 to shake up and down. When the toothed plate 19 moves up and down, the movable slider 20 moves up and down synchronously on the support rod 18, and the springs 21 on the support rod 18 are compressed correspondingly synchronously, ensuring the smoothness of the up and down shaking of the sorting plate 6, and better ensuring that the waste refractory materials can achieve a higher sorting effect during the shaking of the sorting plate 6.

[0016] Further, in order to make the impurity content of the sorted waste refractory materials lower, an electromagnet is installed inside the sorting plate 6, and the sorting holes penetrate through the electromagnet 24. During the process of the sorting plate 6 jitter-sorting the waste refractory materials, after the electromagnet 24 is powered on, it can adsorb the magnetic metals mixed in the waste refractory materials again to achieve the effect of complete separation. Preferably, in order to improve the sorting efficiency, a scraping component is arranged in the sorting box 2 on the upper side of the sorting plate 6. The scraping component includes a transmission lead screw 25, a second motor 26 and a scraping plate 27. The second motor 26 is a prior art and can be directly purchased as a finished product according to the power used. The transmission lead screw 25 is installed in the sorting box 2 in a transmission manner. The second motor 26 is installed outside the sorting box 2 and is in transmission connection with the transmission lead screw 25. A threaded sleeve 28 is screwed on the transmission lead screw 25. An electric telescopic rod 29 is installed at the bottom of the threaded sleeve 28. The scraping plate 27 is installed at the bottom of the electric telescopic rod 29. After the device finishes sorting the waste refractory materials, the electromagnet 24 is powered off and the electromagnet 24 loses its magnetism. At this time, the second motor 26 drives the transmission lead screw 25 to rotate. During the rotation of the transmission lead screw 25, it can drive the threaded sleeve 28, the electric telescopic rod 29 and the scraping plate 27 to move. At the same time, the electric telescopic rod 29 is used to drive the scraping plate 27 to move downwards to contact the sorting plate 6. During the movement of the scraping plate 27, it can scrape up the magnetic metals on the sorting plate 6 and discharge them from the material outlet 5, so that the sorting box 2 can maintain a high magnetic separation and sorting effect during the next use.
