Description

Technical Field

[0001] This utility model relates to the field of industrial solid waste treatment technology, and in particular to a novel industrial solid waste recycling and treatment device. Background Technology

[0002] Industrial solid waste refers to solid waste generated during industrial production activities. It is a type of solid waste, often referred to as industrial waste. It includes various waste residues, dust, and other wastes discharged into the environment during industrial production processes. It can be divided into general industrial waste (such as blast furnace slag, steel slag, red mud, non-ferrous metal slag, fly ash, coal slag, sulfuric acid slag, waste gypsum, desulfurization ash, carbide slag, salt mud, etc.) and hazardous industrial solid waste. Some industrial solid wastes, such as furnace slag, contain recyclable resources, so industrial solid waste often needs to be recycled and reused.

[0003] A search revealed that CN215277912U discloses a solid waste recycling processing device, which includes a grinding shaft, a grinding motor, a crushing motor, a crushing shaft, crushing blades, grinding blocks, a grinding chamber, a discharge port, and a grinding plate. These components work together to crush slag into small pieces, facilitating subsequent grinding and improving the grinding effect. Furthermore, by using an electromagnet in conjunction with a connecting frame, the device can adsorb and remove metals contained in the filter residue, thereby improving the combustion effect when the slag is recycled and then burned.

[0004] The above scheme uses a combination of crushing and grinding to crush industrial waste. Because the crushing effect is quite thorough, some recyclable materials in the industrial waste are mixed with powdery waste, resulting in a significant reduction in the recycling rate of recyclable materials in the industrial waste.

[0005] To address this, a novel industrial solid waste recycling and treatment device is proposed, which has the advantage of easily processing and classifying recyclable materials from waste, thereby solving the problems mentioned in the background technology. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel industrial solid waste recycling and treatment device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a novel industrial solid waste recycling and treatment device, comprising a workbench, a central square cylinder welded to the center of the workbench, and a feed hopper welded to the top of the central square cylinder. Two shredding blade shafts are rotatably mounted inside the central square cylinder via bearings, and the shredding teeth on the surfaces of the two shredding blade shafts are staggered. A reducer is installed on each of the left and right sides of the top surface of the workbench, and the output shaft of the reducer is fixedly connected to the shredding blade shaft via a coupling. Openings are provided on both the left and right sides inside the workbench. The device has mounting cavities, and each mounting cavity contains a fixed motor. A transmission belt is wound between the output end of the motor and the output shaft of the reducer. A screening plate is welded to the lower inner side of the workbench, and the surface of the screening plate has a first hollow structure welded on it. The screening plate is composed of inclined and horizontal parts. A discharge nozzle connected to the central square cylinder is provided on the front surface of the workbench, and the installation height of the discharge nozzle is adapted to the installation height of the horizontal part of the screening plate. A baffle is welded to the left and right edges of the screening plate, and an electromagnet is embedded in the baffle.

[0008] As a further description of the above technical solution: a water supply pipe is provided on the left and right sides inside the central square tube, and several spray pipes are installed at equal intervals on the surface of the water supply pipes. Several nozzles are installed on the surface of each spray pipe, and a second hollow structure is welded to the surface of the screening plate corresponding to the spray pipes.

[0009] As a further description of the above technical solution: both the first hollow structure and the second hollow structure are made of wire mesh, and both the wire mesh of the first hollow structure and the second hollow structure are provided with inclined ends and horizontal ends.

[0010] As a further description of the above technical solution: two sets of baffles are welded at equal intervals on the inner side of the port of the feed hopper, and the baffles are inclined about the feed hopper.

[0011] As a further description of the above technical solution: two guide plates are provided between the shredding blade shaft and the screening plate, and the two guide plates are welded to the inner wall of the central square cylinder, and the two guide plates are arranged in a trumpet-shaped structure.

[0012] As a further description of the above technical solution: the bottom of the central square tube is provided with a powder and slag outlet, and the bottom of the central square tube extends to the bottom of the workbench.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, by starting two motors on the workbench, the two motors drive the reducer to rotate via transmission belts and pulleys. This causes two shredding blade shafts, connected to the reducer's output shaft by a coupling, to rotate. Industrial waste fed from the hopper is then shredded by the two shredding blade shafts inside the central square cylinder. The shredded industrial waste falls onto a screening plate and is separated by the first perforated structure on the screen plate's surface. Powdered or slag-like materials pass through the screening plate and are discharged from the bottom of the central square cylinder, while metal materials or other fragmented materials are discharged from the outlet under gravity. During this process, the electromagnets built into the baffles on both sides of the screening plate are activated, causing fine metal waste in the shredded industrial waste to be adsorbed. Compared with existing technologies, the shredding blade shaft design facilitates efficient shredding of industrial waste, and the electromagnet-equipped screening plate facilitates online separation of lumpy materials, powdered or slag-like materials, and the recovery of magnetic metal materials.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] According to an embodiment of the present invention, a novel industrial solid waste recycling and treatment device is provided.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a novel industrial solid waste recycling and treatment device according to an embodiment of this utility model includes a workbench 1, a central square cylinder 2 welded to the middle of the workbench 1, and a feed hopper 3 welded to the top of the central square cylinder 2. Two shredding blade shafts 10 are rotatably mounted inside the central square cylinder 2 via bearings, and the shredding blades on the surfaces of the two shredding blade shafts 10 are staggered. A reducer 7 is installed on the left and right sides of the top surface of the workbench 1, and the output shaft of the reducer 7 is fixedly connected to the shredding blade shaft 10 via a coupling. Installation cavities 4 are opened on both the left and right sides inside the workbench 1, and a motor 5 is fixed in each installation cavity 4. A transmission belt 6 is wound between the output end of the motor 5 and the output shaft of the reducer 7. A screening plate 12 is welded to the lower inner side of the workbench 1, and a first hollow structure 17 is welded to the surface of the screening plate 12. The screening plate 12 consists of an inclined portion and a water... The workbench 1 is composed of two flat parts. The front surface of the workbench 1 is provided with a discharge nozzle 8 that is connected to the central square cylinder 2. The installation height of the discharge nozzle 8 is adapted to the installation height of the horizontal part of the screening plate 12. The left and right edges of the screening plate 12 are welded with baffles 13, and electromagnets 16 are embedded in the baffles 13. In order to recover magnetic metal materials, the power supply of electromagnets 16 needs to be cut off after the powder and slag materials are completely discharged from the central square cylinder 2, so that the magnetic metal materials can be discharged from the powder and slag outlet at the bottom of the central square cylinder 2, which is convenient for the collection of magnetic metal materials. The motor 5 and the electromagnet 16 are controlled by manually starting and stopping the switch. The wiring diagram of the power components and the power supply are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0024] In one embodiment, a water supply pipe 9 is provided on the left and right sides inside the central square tube 2, and several spray pipes 14 are installed at equal intervals on the surface of the water supply pipe 9. Several nozzles are installed on the surface of each spray pipe 14. A second hollow structure 18 is welded to the surface of the screening plate 12 corresponding to the spray pipes 14. Clean water is pumped into the water supply pipe 9 by an external booster pump, which causes the several spray pipes 14 connected to the water supply pipe 9 to spray clean water onto the screening plate 12 using the nozzles on their surfaces. This can clean the blocky material on the surface of the screening plate 12, and on the one hand, it can clean the powdery residue attached to the surface of the blocky material, and on the other hand, it provides convenience for the further sorting of the blocky material.

[0025] In one embodiment, both the first perforated structure 17 and the second perforated structure 18 are made of wire mesh. The wire mesh of the first perforated structure 17 and the second perforated structure 18 are provided with inclined ends and horizontal ends. By providing inclined ends and horizontal ends, the first perforated structure 17 and the second perforated structure 18 can adapt to the contours of the screening plate 12 and the baffle 13. Since the composition of different types of solid industrial waste is complex and there are many types of recyclable materials, the wire mesh aperture of the first perforated structure 17 can be flexibly selected according to the actual screening requirements.

[0026] In one embodiment, two sets of baffles 11 are welded at equal intervals on the inner side of the port of the feed hopper 3, and the baffles 11 are inclined about the feed hopper 3. By setting the two sets of baffles 11, the amount of industrial waste ejected during the crushing stage can be reduced.

[0027] In one embodiment, two guide plates 15 are provided between the shredder shaft 10 and the screening plate 12, and the two guide plates 15 are welded to the inner wall of the central square tube 2. The two guide plates 15 are arranged in a trumpet-shaped structure. By setting the two guide plates 15, the crushed material is concentrated and guided to the screening plate 12 on the one hand, and the spray pipe 14 is shielded and protected on the other hand.

[0028] In one embodiment, the bottom of the central square tube 2 is provided with a powder and slag outlet, and the bottom of the central square tube 2 extends to the bottom of the workbench 1. The powder and slag outlet facilitates the discharge of powder and slag materials.

[0029] Working principle:

[0030] In operation, the two motors 5 on the workbench 1 are started, causing them to drive the reducer 7 via the transmission belt 6 and pulley. This causes the two shredding blade shafts 10, connected to the output shaft of the reducer 7 by a coupling, to rotate. The industrial waste fed from the feed hopper 3 is then shredded by the two shredding blade shafts 10 inside the central square cylinder 2. The shredded waste falls onto the screening plate 12 and is separated by the first perforated structure 17 on the surface of the screening plate 12. Powdered or slag-like materials pass through the screening plate 12 and are discharged from the powder / slag outlet at the bottom of the central square cylinder 2, while metal materials or other fragmented materials are separated. Under the action of gravity, the material is discharged from the discharge nozzle 8. During this process, the electromagnets 16 installed inside the baffles 13 on both sides of the screening plate 12 are activated, so that the fine metal waste in the crushed industrial waste is adsorbed. At the same time, the external booster pump pumps clean water into the water supply pipe 9, causing several spray pipes 14 connected to the water supply pipe 9 to spray clean water onto the screening plate 12 with the nozzles on their surfaces. This can clean the blocky material on the surface of the screening plate 12, on the one hand, it can clean the powdery residue attached to the surface of the blocky material, and on the other hand, it can facilitate the further sorting of the blocky material in the later stage.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
