Description

Technical Field

[0001] The invention belongs to the technical field of classification and cleaning mechanisms, and in particular relates to a classification and cleaning mechanism for industrial solid waste. Background Art

[0002] Industrial solid waste refers to solid waste generated in industrial production activities, a type of solid waste, referred to as industrial waste. Metallurgical solid waste, such as blast furnace slag, steel slag, ferroalloy slag, etc., is mainly generated in the metal smelting process. These industrial solid wastes will be classified by screening. The materials with smaller particle sizes will be used to produce cement, concrete aggregate and other building materials after screening and classification, and the materials with larger particle sizes can be used for road base materials after screening and classification. At the same time, the above-mentioned industrial solid wastes also contain many magnetic substances, which can further play their value after screening.

[0003] The Chinese patent application number 2023233106336 discloses an industrial solid waste classification and collection device, including a cleaning mechanism and a sorting device. The cleaning mechanism includes a first conveyor belt, a spraying mechanism and a water circulation mechanism. The first conveyor belt includes a horizontally arranged front section and an inclined upward conveying rear section. The belt body of the first conveyor belt is a filter cloth. The spraying mechanism includes a water spraying pipe and a nozzle arranged above the rear section of the first conveyor belt. The water spraying pipe is connected to a water inlet pipe. The water circulation mechanism includes a collection tank arranged below the first conveyor belt, a circulating water pipe connected to the water spraying pipe, and a water pump arranged on the circulating water pipe. The collection tank includes a sludge tank, a water storage tank and a filter plate. The circulating water pipe is connected to the water storage tank. The sorting device is arranged at the rear side of the cleaning mechanism. The sorting device includes a second conveyor belt, a sorting mechanism arranged above the second conveyor belt, and an ironware collection box arranged on one side of the second conveyor belt.

[0004] The above scheme cleans the industrial solid waste before sorting, removes dust and dirt and other impurities on the surface of the industrial solid waste, and sets a magnet above the conveyor belt to adsorb and sort metals such as iron, cobalt, and nickel in the industrial solid waste. However, the above scheme has the following defects: 1. Cleaning is performed before sorting. During the cleaning process, impurities such as oil, rust, and sand on the surface of the metallurgical solid waste will be removed, but at the same time, some valuable magnetic substances (such as iron oxides, metallic iron, etc.) may be washed away, especially when these magnetic substances exist in the form of tiny particles, which will lead to a decrease in the content of magnetic substances in the material; 2. The magnet is set above the conveyor belt and does not contact the material, which results in its limited magnetic adsorption force on the magnetic substances in the material, making it difficult to fully adsorb the magnetic substances in the solid waste.

[0038] Embodiment 1, combination Figure 1-3 , an industrial solid waste classification and cleaning mechanism, comprising a processing machine base 1, a rotary reciprocating conveying mechanism, a classification screen drum 2 and a cleaning mechanism, wherein a classification chamber 3 is provided inside the processing machine base 1, and a cleaning chamber 4 is connected to the bottom of the classification chamber 3, the classification screen drum 2 is fixedly arranged in the classification chamber 3, and the cleaning mechanism is arranged in the cleaning chamber 4. The classification screen drum 2 in the classification chamber 3 is used to screen industrial solid waste of different particle sizes, and a large sieve hole area 5 and a small sieve hole area 6 are provided on the surface of the classification screen drum 2, and a plurality of large sieve holes are provided on the large sieve hole area 5, and the diameter of the large sieve hole ranges from 20 to 100 mm, and is specifically 50 mm in this embodiment, while the diameter of the small sieve hole ranges from 1 to 10 mm, and is specifically 5 mm in this embodiment. A feed pipe 7 is connected to the top of the processing machine base 1 above the small sieve hole area 6, and a feed port 8 connected to the feed pipe 7 is provided above the small sieve hole area 6. Industrial solid waste as material first enters the small sieve hole area 6 in the classification screen drum 2 from the feed pipe 7, and then the rotary reciprocating conveying mechanism drives the material to reciprocate in the small sieve hole area 6, so that the small-sized material is continuously screened out from the small sieve hole area 6, and then the rotary reciprocating conveying mechanism drives the remaining material into the large sieve hole area 5, and the large sieve hole area 5 screens out the large-sized material.

[0039] The rotary reciprocating conveying mechanism includes a rotary reciprocating drive device 9 and a spiral conveying plate 10. The rotary reciprocating drive device 9 is arranged on one side of the processing machine base 1, and the spiral conveying plate 10 is arranged on the inner side of the classification screen cylinder 2. The output end of the rotary reciprocating drive device 9 extends into the classification screen cylinder 2 and is connected to the spiral conveying plate 10. The rotary reciprocating drive device 9 drives the spiral conveying plate 10 to reciprocate and rotate. The rotary reciprocating drive device 9 is composed of a stepping motor and a rotary motor. A support plate for support is provided below the two motors. A combination of a slide plate and a slide rail is provided at the bottom of the rotary motor, so that the rotary motor can reciprocate along the slide rail on the support plate. The output end of the rotary motor is connected to one end of the spiral conveying plate 10 to drive the spiral conveying plate 10 to rotate. The output end of the stepping motor is connected to the tail of the rotary motor, and the stepping motor drives the rotary motor and the spiral conveying plate 10 to reciprocate. The spiral conveying plate 10 stirs and moves the material in the continuous reciprocating and rotating motion, so that the material completes the screening work. After the material is screened, it falls into the cleaning chamber 4 below to complete the cleaning work. In addition to the above structure, any motor on the market that can perform rotation and linear reciprocating motion can be used in the rotary reciprocating drive device 9.

[0040] Combination Figure 4-5 A magnetic separation chamber 11 is provided on the side of the processing machine base 1. The upper part of the magnetic separation chamber 11 is connected to the classification chamber 3. A collecting device is provided at the bottom of the magnetic separation chamber 11. The magnetic separation chamber 11 is used to collect magnetic substances. The magnetic substances are transported by the spiral conveying plate 10. An electromagnet (not shown in the figure) is provided inside the spiral conveying plate 10. When the spiral conveying plate 10 is in continuous contact with the material, the electromagnet inside the spiral conveying plate 10 will generate magnetic force to adsorb the magnetic substances in the material. When the material is screened, the spiral conveying plate 10 adsorbed with the magnetic substances is moved to the upper part of the magnetic separation chamber 11, and the electromagnet inside the spiral conveying plate 10 is stopped from being powered, and the magnetic adsorption force is released, and the magnetic substances fall from the spiral conveying plate 10 to the lower part of the magnetic separation chamber 11.

[0041] In this embodiment, a first control switch 12 is provided on the right side above the magnetic separation chamber 11, and the first control switch 12 is electrically connected to the electromagnet inside the spiral conveying plate 10. A moving plate 13 is provided at the front end of the first control switch 12, and a first spring 14 is connected between the moving plate 13 and the side wall of the magnetic separation chamber 11. After the screening is completed, the rotary reciprocating drive device 9 drives the spiral conveying plate 10 with the magnetic material adhered to it to the magnetic separation chamber 11. After the spiral conveying plate 10 and the moving plate 13 are against each other, the moving plate 13 is driven to press the first control switch 12, so that the electromagnet inside the spiral conveying plate 10 is disconnected from the current. At this time, the magnetic material on the spiral conveying plate 10 will fall to the bottom of the magnetic separation chamber 11. After the magnetic material falls, the spiral conveying plate 10 is reset, and the moving plate 13 will also be reset under the action of the first spring 14. The spring inside the first control switch 12 will also drive the first control switch 12 to reset, and the control electromagnet power supply circuit will resume power supply. Through the cooperation of the first control switch 12 and the moving plate 13, the intelligent control of the electromagnet power supply circuit is realized. When the spiral conveyor plate 10 is completely moved to the top of the magnetic separation chamber 11, the current of the electromagnet can be automatically disconnected to allow the magnetic material to fall smoothly. When the spiral conveyor plate 10 is reset, the power supply of the electromagnet can be automatically restored to prepare for the next screening.

[0042] In order to further ensure that the magnetic material can fall from the spiral conveyor plate 10, a fan 52 is provided on the top of the magnetic separation chamber 11, and the fan 52 is also electrically connected to the first control switch 12. When the first control switch 12 controls the electromagnet to be powered off, the fan 52 is controlled to start, so as to ensure that the magnetic material falls smoothly. In addition to the above structure, this embodiment also provides another alternative solution, such as Figure 6 As shown, a plurality of air nozzles 53 are provided on the top of the magnetic separation chamber 11, an air duct 54 is fixedly provided on the outer side above the magnetic separation chamber 11, a sliding rod 55 is connected to one side of the movable plate 13, the sliding rod 55 is connected to an elastic air bag 56, the interior of the elastic air bag 56 is connected to the air duct 54, and one end of the air duct 54 is connected to a plurality of air nozzles 53. Whenever the spiral conveying plate 10 moves to the right to squeeze the movable plate 13, not only will the electromagnet in the spiral conveying plate 10 be disconnected, but the movable plate 13 will also drive the sliding rod 55 to squeeze the elastic air bag 56, and the elastic air bag 56 squeezes the air from the air duct 54 to the air nozzle 53, and the air is ejected from the air nozzle 53 onto the spiral conveying plate 10. When the spiral conveying plate 10 moves to a specific position, the jet function can be automatically triggered without manual intervention to ensure that the magnetic material falls smoothly. Compared with the way in which the fan 52 needs to consume energy, this alternative can have obvious advantages in energy saving.

[0043] A separation device is provided in the middle of the magnetic separation chamber 11, and the separation device includes a guide plate, a hollow rotating roller 27, a fixed magnet 28 and a partition plate 29. The guide plate includes a first guide plate 30 and a second guide plate 31. The hollow rotating roller 27 is rotatably arranged in the middle position of the magnetic separation chamber 11. One end of the first guide plate 30 is fixed to the left side of the magnetic separation chamber 11, and the other end of the first guide plate 30 extends to the top of the hollow rotating roller 27. One end of the second guide plate 31 is fixed to the right side of the magnetic separation chamber 11, and the other end of the second guide plate 31 extends to the top of the first guide plate 30. The function of the first guide plate 30 and the second guide plate 31 is to guide the fallen magnetic material and partially mixed non-magnetic material to the top of the hollow rotating roller 27.

[0044] The cross section of the fixed magnet 28 is a semi-circular structure, the end of the fixed magnet 28 is fixedly connected to the side wall of the magnetic separation chamber 11 and the opening of the fixed magnet 28 is set to the left, and one end of the hollow rotating roller 27 is connected to the corresponding rotating drive device, so as to realize clockwise rotation. The other end of the hollow rotating roller 27 is an open structure, so that the fixed magnet 28 is fixedly connected to the side wall of the magnetic separation chamber 11. The magnetic material will fall onto the surface of the hollow rotating roller 27 together with part of the mixed non-magnetic material. Since the hollow rotating roller 27 keeps turning clockwise to the right, part of the mixed non-magnetic material will fall to the lower right side of the magnetic separation chamber 11, and the magnetic material will continue to be adsorbed on the surface of the hollow rotating roller 27 due to the presence of the fixed magnet 28. As the hollow rotating roller 27 rotates to the left, it will be separated from the magnetic adsorption of the fixed magnet 28 and then fall to the lower left side of the magnetic separation chamber 11. The partition plate 29 is fixed in the middle position of the collecting device, and the upper part of the partition plate 29 extends to the bottom of the hollow rotating roller 27, and a gap 32 is formed between the partition plate 29 and the bottom of the hollow rotating roller 27. The gap 32 is used for the magnetic material to pass through, and the partition plate 29 is used to prevent the magnetic material on the left side from falling to the lower right side of the magnetic separation chamber 11, thereby avoiding the re-mixing of the magnetic material and the non-magnetic material. By combining the design of the guide plate, the hollow rotating roller 27 and the fixed magnet part 28, this embodiment can further efficiently separate the magnetic material and the non-magnetic material. The magnetic material is firmly adsorbed on the hollow rotating roller 27 under the magnetic force of the fixed magnet part 28, and falls after it rotates to the area without magnetic force, thereby realizing the accurate collection of the magnetic material.

[0045] In the process of conveying materials by the spiral conveyor plate 10 in this embodiment, since the spiral conveyor plate 10 is in direct contact with the materials, this contact adsorption method greatly shortens the distance of magnetic force, thereby significantly enhancing the attraction of magnetic force to magnetic substances in the materials. Even tiny or deeply buried magnetic particles can be effectively adsorbed under the action of strong magnetic force. The spiral conveyor plate 10 is not only responsible for the conveying of materials, but also stirs and turns the materials through its rotation and reciprocating motion. This dynamic process ensures that the electromagnet can fully contact and adsorb every magnetic particle in the material, greatly improving the adsorption coverage rate of magnetic substances. A blocking rod 33 is provided at the upper left of the hollow rotating roller 27, and bristles 34 are provided on the blocking rod 33. The bristles 34 are arranged close to the surface of the hollow rotating roller 27. The blocking rod 33 and the bristles 34 are used to brush off the magnetic substances that have not fallen off the surface of the hollow rotating roller 27, and at the same time prevent non-magnetic substances from falling from the top to the lower left of the magnetic separation chamber 11.

[0046] Combination Fig.13 , below the magnetic separation chamber 11 is a collecting device, which includes a box body 44, the middle of the box body 44 is divided into a magnetic material collecting chamber 45 and a non-magnetic material collecting chamber 46 by a partition plate 29, the magnetic material collecting chamber 45 is used to collect magnetic materials, and the non-magnetic material collecting chamber 46 is used to collect non-magnetic mixtures. An automatic discharging device is provided in the magnetic material collecting chamber 45, and the automatic discharging device includes a linear motor 47, the output end of the linear motor 47 is connected to an L-shaped plate 48, a weighing plate 49 is provided above the bottom of the L-shaped plate 48, and a weighing sensor 50 is provided at the bottom of the weighing plate 49, and the weighing sensor 50 can sense the weight of the magnetic material on the weighing plate 49. When the mass of the magnetic material reaches the specified target, the linear motor 47 pushes the L-shaped plate 48 outward to complete the collection of the magnetic material. The top of the L-shaped plate 48 is also connected to a baffle plate 51, which extends to the top of the non-magnetic material collection chamber 46. When the L-shaped plate 48 is pushed outward, the baffle plate 51 on its top will also move to the left with the movement of the L-shaped plate 48. Its purpose is to prevent subsequent magnetic materials from falling between the L-shaped plate 48 and the linear motor 47 when the L-shaped plate 48 moves to the left, so that they cannot be stuck in the dead corner, which is not only difficult to collect but also easily affects the resetting of the L-shaped plate 48.

[0047] Embodiment 2, combined Figure 7-10, this embodiment has the same parts as embodiment 1, except that in this embodiment, the spiral conveying plate 10 includes a first spiral plate 15 and a second spiral plate 16, the electromagnet is arranged in the second spiral plate 16, a slot 17 is provided at one end of the second spiral plate 16, an insertion portion 18 is provided at one end of the first spiral plate 15, the insertion portion 18 is inserted into the slot 17, limiting slideways 19 are provided on both sides of the inner side of the slot 17, sliders 20 are provided on both sides of the insertion portion 18, the sliders 20 are slidably arranged in the limiting slideways 19, a first groove 21 is provided in the middle of the bottom end of the slot 17, second grooves 22 are provided on both sides of the first groove 21, a second control switch 23 is provided in the first groove 21, a second spring 24 is provided in the second groove 22, the other end of the second spring 24 is connected to the insertion portion 18, and an abutment block 25 is provided at the end of the insertion portion 18. The second control switch 23 is used to control the power on and off of the electromagnet inside the second spiral plate 16. The electromagnet inside the second spiral plate 16 can be powered by a built-in power supply or an external power supply. In this solution, the power cord is sent from the first spiral plate 15 to the second spiral plate 16 by an external power supply, so as to ensure the power supply of the electromagnet inside the second spiral plate 16. The electromagnet is arranged in the second spiral plate 16 to reduce the length of the adsorption part of the entire spiral conveying plate 10. Since the space above the magnetic separation chamber 11 is limited and the entire spiral conveying plate 10 cannot be fully accommodated, it is necessary to reduce the length of the adsorption part of the entire spiral conveying plate 10 to prevent the magnetic material adsorbed on the spiral conveying plate 10 from falling below the magnetic separation chamber 11. The first spiral plate 15 and the second spiral plate 16 are connected together by sliding through the insertion portion 18 and the slot 17. A second spring 24 is also connected between the bottom of the slot 17 and the insertion portion 18. The second spring 24 can make the first spiral plate 15 drive the second spiral plate 16 to rotate, while the abutment block 25 on the end of the insertion portion 18 will not directly press the second control switch 23. Only when the second spiral plate 16 moves to the magnetic separation chamber 11 and abuts against the abutment plate 26 on the upper side wall of the magnetic separation chamber 11, and the second spiral plate 16 cannot rotate, the insertion portion 18 will further compress the spring, so that the abutment block 25 can press the second control switch 23 in the first groove 21, thereby disconnecting the current of the electromagnet in the second spiral plate 16.

[0048] The electromagnet in the second spiral plate 16 is in an energized adsorption state in the initial stage. When the material screening work is completed and it moves to the top of the magnetic separation chamber 11, the end of the second spiral plate 16 abuts against the abutment plate 26, so that the abutment block 25 can press the second control switch 23 in the first groove 21, thereby disconnecting the current of the electromagnet in the second spiral plate 16, releasing the adsorption force on the magnetic material, and causing the magnetic material to fall to the bottom of the magnetic separation chamber 11. After the second spiral plate 16 moves away from the abutment plate 26, under the action of the second spring 24, the abutment block 25 moves away from the second control switch 23, and the second spiral plate 16 can resume the adsorption effect on the magnetic material. Through the coordinated use of the second control switch 23 and the second spring 24, the automatic on and off control of the electromagnet power supply is realized, the automation degree of the equipment is improved, and the accuracy and efficiency of material screening are ensured.

[0049] Embodiment 3, combined Figure 11-12 This embodiment is a further description of the cleaning mechanism. The cleaning mechanism includes a rotating tube 35, which is rotatably arranged in the cleaning chamber 4. A first partition 36 is provided in the middle of the cleaning chamber 4. The first partition 36 divides the cleaning chamber 4 into a first cleaning chamber 37 and a second cleaning chamber 38. The two cleaning chambers 4 are used to clean materials of different particle sizes. A plurality of water pipes 39 are fixed around the rotating tube 35. The end of each water pipe 39 is vertically connected to a water spray pipe 40. The water spray pipe 40 passes through the rotating tube 35 and extends into the cleaning chamber 4. A water spray hole 41 is opened on the water spray pipe 40. The end of the rotating tube 35 is connected to a rotating mechanism. The rotating mechanism drives the rotating tube 35 to rotate, so that the water spray pipe 40 rotates and stirs while spraying water. The plurality of water pipes 39 in the rotating tube 35 and the water spray pipes 40 connected thereto can form multi-point water spraying in the cleaning chamber 4, thereby increasing the cleaning area and cleaning strength, thereby improving the cleaning efficiency. The water spray pipes 40 rotate and stir while spraying water. This design can break the bubbles and dirt in the cleaning liquid and make it easier for them to be taken away by the cleaning liquid. The stirring effect can also promote the chemical components in the cleaning liquid to be more evenly distributed on the surface of the object to be cleaned, thereby improving the chemical reaction speed and the cleaning effect.

[0050] A circular connecting portion 42 is provided at intervals 32 on the plurality of water pipes 39, and a diversion cavity 43 is provided inside the circular connecting portion 42. The diversion cavity 43 is connected to the plurality of water pipes 39. The circular connecting portion 42 is used to prevent a single water pipe 39 from being blocked and unable to supply water. If a node of a single water pipe 39 is blocked, water in other water pipes 39 will flow back into the water pipe 39 through the next circular connecting portion 42 of the blocked node, so as to ensure that the water in the water pipe 39 can be continuously discharged.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
