Technical Field

[0001] This utility model relates to the field of waste metal scrap recycling and processing technology, and in particular to an iron scrap crushing and briquetting production line. Background Technology

[0002] Industrial production processes generate a large amount of metal scrap waste. If this metal scrap waste is not treated, it will cause environmental pollution and waste resources. The metal product machining industry usually uses cutting oil or cutting fluid for machining, which causes the metal scrap waste to be contaminated with impurities such as oil / water, hydrocarbon / water mixtures, emulsions, or waste mineral oil during the processing. If the petroleum solvent content in these contaminated impurities is ≥3%, it can be identified as hazardous waste. Not only can it not be recycled, but it also causes environmental pollution.

[0003] Chinese Patent Publication No. CN213261237U discloses a waste metal scrap briquetting production line, which includes two rows of briquetting equipment groups arranged in parallel and spaced apart. Each row of briquetting equipment groups includes a number of waste metal scrap briquetting modules arranged in a straight line at intervals. A collection bin is arranged at the front end of the two rows of briquetting equipment groups, and a stacking device is arranged at the rear end. A number of belt conveyors are arranged on the outside of the two rows of briquetting equipment groups to transport the waste metal scrap in the collection bin to the corresponding waste metal scrap briquetting module. A common briquetting conveyor is arranged in the middle of the two rows of briquetting equipment groups. The discharge port of the waste metal scrap briquetting module is located above the briquetting conveyor, so as to realize the efficient and integrated production of waste metal scrap briquetting.

[0004] However, the existing technology still has the following problems: the design structure is complicated and the footprint is large, which to some extent makes the overall layout of the scrap metal briquetting production line inflexible and wastes space. Utility Model Content

[0005] Therefore, this utility model provides an iron filings crushing and briquetting production line to overcome the problems of complex overall production line structure and large footprint in the prior art.

[0006] To achieve the above objectives, this utility model provides an iron filings crushing and briquetting production line, comprising:

[0015] Furthermore, the third conveying mechanism includes a centralized feeding bin for receiving chips conveyed from the discharge port, and a chain conveyor for conveying the chips in the centralized feeding bin to the horizontal briquetting machine.

[0016] Furthermore, the chain conveyor feeds material to the horizontal briquetting machine according to a preset time and a preset material weight.

[0017] Furthermore, the lifting and tilting machine includes a housing assembly with a lifting and tilting component inside, wherein the lifting and tilting component is driven to tilt based on a hydraulic system to dump the chips into the interior of the single-shaft crusher.

Figure 3 This is a top view of the overall structure of the iron filings crushing and pressing production line of this utility model;

[0033] This utility model provides an iron filings crushing and briquetting production line, comprising:

[0034] The pretreatment unit includes a lifting and turning machine 1 for receiving chip feed, and a single-shaft crusher 2 for receiving and crushing the chips conveyed by the lifting and turning machine 1.

[0035] The intermediate processing unit includes a metal centrifugal dryer 4 for receiving and dehydrating / de-oiling the chips processed by the single-shaft crusher 2, and a storage device 6 for receiving the chips processed by the metal centrifugal dryer 4.

[0036] Tail-end processing mechanism, which includes a horizontal briquetting machine 8 for receiving the chips stored in the storage device 6 and compressing the chips into blocks;

[0037] A connecting mechanism is used to connect the pre-processing unit, the intermediate processing unit, and the tail-end processing unit so that the pre-processing unit, the intermediate processing unit, and the tail-end processing unit are interconnected and form a production line.

[0038] Specifically, the connecting mechanism includes a first conveyor 3 for connecting the single-shaft crusher 2 and the metal centrifugal dryer 4, a second conveyor 5 for connecting the metal centrifugal dryer 4 and the storage device 6, and a third conveyor 7 for connecting the storage device 6 and the horizontal briquetting machine 8.

[0039] In this embodiment, the first conveyor 3, the second conveyor 5, and the third conveyor 7 all have enclosed conveying sections for conveying chips. The third conveyor 7 includes a centralized feeding bin for receiving chips conveyed from the discharge port, and a chain conveyor for conveying chips from the centralized feeding bin to the horizontal briquetting machine 8. The enclosed conveying section of the third conveyor 7 is a sealed chain conveyor. The first conveyor 3, the second conveyor 5, and the third conveyor 7 are all equipped with enclosed conveying sections for conveying chips to prevent metal chip leakage and thus ensure the overall airtightness of this utility model. In addition, the chain conveyor feeds materials to the horizontal briquetting machine 8 according to a preset time and a preset feeding weight. When conveying chips, the third conveyor 7 first conveys them from the discharge port of the storage device 6 to the centralized feeding bin, and then works in conjunction with the chain conveyor to convey them to the briquetting machine according to a preset quantitative and timed method, further ensuring continuous and stable feeding and discharging.

[0040] Please see Figure 4 The diagram shows the structure of the metal centrifugal dryer 4 in the iron scrap crushing and briquetting production line of this utility model. The metal centrifugal dryer 4 includes an inlet 41 for receiving the chips conveyed by the first conveyor 3, an outer shell 42 connected to the inlet 41 and having a centrifugal drum 43 inside, an outlet 44 connected to the outer shell 42 for conveying the chips to the second conveyor 5, and an oil discharge port 45 opened in the outer shell 42 for draining the centrifugal oil from the chips. After the chips are processed by the metal centrifugal dryer 4, the chips remain inside the centrifugal drum 43 for further processing, while the cutting oil and cutting fluid are thrown to the inner wall of the outer shell 42 and conveyed to the outside through the oil discharge port 45, so that the cutting oil can be recycled and reused. This not only saves resources but also reduces environmental pollution, meeting environmental protection requirements. Furthermore, each link adopts an optimized process design, especially the crushing, dehydration, deoiling, and briquetting links, ensuring work efficiency and energy saving. This improvement increases production capacity while reducing energy consumption.

[0041] The centrifugal drum 43 has an adjustable rotation speed, which allows the present invention to use different centrifugal speeds when processing chips of different metal materials, thereby better separating the cutting oil and cutting fluid mixed in the chips and greatly increasing the practicality of the present invention.

[0042] In this embodiment of the present invention, the storage device 6 includes a storage bin with a storage port facing the second conveyor 5, and several spiral blades disposed inside the storage bin for conveying chips from the storage bin to the discharge port. The discharge port is located on the side of the storage bin facing the third conveyor 7 and is used to discharge the chips conveyed by the spiral blades to the third conveyor 7. In the above structure, the chips processed by the metal centrifugal dryer 4 are conveyed through the discharge port 44 to the storage bin of the storage device 6 via the second conveyor 5. This device can not only store chips, but also convey chips to the discharge port through the rotation of the spiral blades, so as to ensure that the chips in the storage device 6 are sent to the next stage, and further ensure continuous and stable feeding.

[0043] In this embodiment, the lifting and tilting machine 1 includes a housing assembly with a lifting and tilting component inside. The lifting and tilting component is driven to tilt by a hydraulic system so that the chips are dumped into the single-shaft crusher 2. An external trolley transports waste chips to the lifting and tilting machine 1. The trolley is an automated control process trolley, so that the process flow and power system of each link of this utility model adopt a high-efficiency and low-energy consumption design scheme.

[0044] The present invention also includes a control component in the iron filings crushing and pressing production line. The control component is connected to the pretreatment mechanism, the intermediate treatment mechanism, the tail section treatment mechanism and the connecting mechanism by signal, and is used to drive and regulate the working status of the pretreatment mechanism, the intermediate treatment mechanism, the tail section treatment mechanism and the connecting mechanism.

[0045] Specifically, the control component can be a PLC control system, through which the entire production line is automatically scheduled and controlled. The system can monitor and adjust each step in real time according to the set workflow, ensuring stable equipment operation and improving work efficiency. This control system is easy to operate, has highly efficient automation capabilities, and can effectively reduce manual intervention.

[0046] The specific embodiments of this utility model will be described in detail below:

[0047] First, before the pre-processing unit starts working, a trolley transports waste chips to the inside of the lifting and tilting machine 1. The protective door is manually closed. The lifting and tilting machine 1, driven by a hydraulic system, lifts and tilts the chips in the chip trolley, accurately feeding them into the single-shaft crusher 2 for subsequent processing. After receiving the chips, the single-shaft crusher 2 crushes large chips into smaller particles through mechanical crushing. This step prepares for the subsequent dehydration, deoiling, and briquetting processes.

[0048] When the intermediate processing unit is working, the crushed chips are fed into the centrifugal drum 43 inside the outer shell 42 of the metal centrifugal dryer 4 through the feed port 41 via the first conveyor 3. The chips are de-oiled and de-fluided by the centrifugal force generated by the high-speed rotating centrifugal drum 43. The cutting oil and cutting fluid are thrown to the inner wall of the outer shell 42 and then transported to the outside through the oil discharge port 45. The solid chips are retained on the inner wall of the centrifugal drum 43. Through this process, the oil content of the chips can be reduced to below 3%, which meets the waste metal processing standards. After being processed by the metal centrifugal dryer 4, the chips are transported to the storage bin of the storage device 6 through the discharge port 44 via the second conveyor 5. This device can not only store chips, but also transport chips to the discharge port through the rotation of the spiral blades to ensure that the chips in the storage device 6 are sent to the next stage, further ensuring a continuous and stable supply.

[0049] Finally, the chips are further compressed into blocks using a small horizontal briquetting machine 8. The briquetting machine features a compact design, enabling efficient compression of the chips while effectively removing residual cutting oil. The briquettinged metal blocks are not only easy to store and transport but also ensure that they are not contaminated during subsequent metal smelting.

[0050] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
