Description

Technical Field

[0001] This utility model relates to the field of resource recycling and environmental protection equipment, specifically to a metal waste dehydration and recycling device. Background Technology

[0002] In the metal processing and related industries, the treatment of metal scrap has always been a crucial step. Metal scrap typically contains a large amount of attached moisture. If it is not effectively dehydrated and recycled, it will not only increase subsequent transportation and storage costs, but may also cause further corrosion of the metal due to the moisture, reducing the recycling value of the metal scrap. Therefore, efficient metal scrap dehydration and recycling technology is of paramount importance.

[0003] Currently, centrifugal dewatering is a common technology for dehydrating metal scrap. This method involves placing a container of metal scrap inside a centrifuge, where high-speed rotation generates strong centrifugal force. This force separates the water from the metal scrap, throwing it to the edge of the container and discharging it. The principle is based on the difference between centrifugal force and the material's gravity, which causes the water to overcome its adhesion to the metal scrap and detach.

[0004] However, this centrifugal dewatering technology has significant drawbacks. The high-speed rotation generated during centrifugation can easily cause mechanical damage to metal waste, especially some softer or oddly shaped metal waste, which may deform or break under centrifugal force, affecting subsequent recycling and processing. On the other hand, centrifugal dewatering equipment has a complex structure, high energy consumption, and high operating costs. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a metal waste dewatering and recycling device. By setting a boss with a groove and a drain outlet in the water tank and a filter box with filter holes on the side, and equipping a dewatering component mounted on the outer edge of the boss groove that can drive the pressure block to press down the metal waste, the device adopts the extrusion method instead of the centrifugal method, thereby realizing a high-efficiency, low-consumption and non-damaging metal waste dewatering and recycling process.

[0006] Technical Solution: This utility model provides a metal waste dewatering and recycling device, comprising: a water tank, the inside of which is provided with a boss, and the top of the boss is provided with a downward-facing groove, the groove wall is provided with multiple drain outlets, a filter box with an upward opening is placed inside the tank, the metal waste is placed inside the filter box, and each side of the filter box is provided with multiple filter holes; a dewatering component, the dewatering component is mounted on the outer edge of the groove at the top of the boss, the dewatering component includes a pressing block, the pressing block is directly opposite the filter box opening, the dewatering component drives the pressing block to move downward into the filter box, squeezing the metal waste, and the squeezed water flows into the water tank through the drain outlet. The filter box provides space for metal scrap, and its numerous filter holes on the side allow the water seeping out of the metal scrap during the extrusion process to be discharged in time, achieving initial solid-liquid separation and facilitating subsequent dewatering operations. The drain outlets on the raised and recessed walls can guide the water squeezed out of the filter box into the water tank, which is conducive to the centralized collection of wastewater and facilitates subsequent treatment. Under the power drive, the pressing block of the dewatering component can apply vertical downward pressure to the metal scrap in the filter box, squeezing out the water contained in the metal scrap to the maximum extent, completing the dewatering operation and improving dewatering efficiency.

[0007] Furthermore, in this application, a metal scrap dewatering and recycling device includes a dewatering assembly comprising a frame, a moving platform, a motor, and a pressing mechanism. The frame is mounted on the outer edge of a groove and includes a top plate, a pair of guide rails, and a set of guide pillars. The lower ends of the guide rails and guide pillars are mounted on the outer edge of the groove, and the upper ends are connected to the top plate. The moving platform is located between the groove and the top plate and is slidably connected to the guide pillars via pulleys on both sides. The motor is connected to the guide rails via a slider. The pressing block is detachably mounted below the moving platform. The pressing mechanism is located between the top plate and the moving platform, and the motor drives the pressing mechanism to apply downward pressure to the moving platform. The top plate, guide rails, and guide pillars of the frame form a stable structure, providing solid support for the entire dewatering assembly. The guide rails and guide pillars not only connect the top plate to the outer edge of the groove but also play a crucial guiding role during the operation of the moving platform, ensuring its vertical and stable movement and allowing the pressing block to accurately apply pressure to the metal scrap. The moving platform achieves smooth vertical displacement by sliding connection between the pulleys on both sides and the guide pillars, and the power generated by the motor is efficiently transmitted to the pressing mechanism. Driven by a motor, the extrusion mechanism pushes the moving table downwards with the pressure block, applying extrusion pressure to the metal scrap to complete the dehydration process. The pressure block is detachably installed under the moving table, allowing for quick and convenient operation when the pressure block wears out or when a special pressure block needs to be replaced for different types of metal scrap, without affecting the overall operation of the equipment.

[0008] Furthermore, in this application, a metal waste dewatering and recycling device includes an extrusion mechanism comprising an upper plate, a lower plate, a screw, a coupling, and four arms. The upper plate is mounted on the underside of a top plate, and the lower plate is mounted on the upper side of a moving platform. One end of the screw is connected to a motor via a coupling, and the other end is connected to a slider away from the motor. The four arms are hinged in pairs to form a scissor structure, with their upper and lower ends hinged to the upper and lower plates respectively, and their middle sections hinged to nuts on the screw. When the motor drives the screw to rotate, the nuts move along the screw, causing the arms to extend or retract, thereby moving the moving platform upwards or downwards. The motor also moves relative to the guide rail. During the process of the motor driving the screw to rotate, the movement of the nuts causes the arms to move, and the motor moves relative to the guide rail. This linkage mechanism makes the entire extrusion process more coordinated and stable.

[0009] Furthermore, in this application, a metal scrap dewatering and recycling device includes a rectangular groove and a baffle. A notch is provided on one side of the groove, and the baffle is adapted to the notch and rotatably connected to the bottom of the groove via a hinge. A first handle is provided on the side of the baffle away from the hinge. When the baffle is flat, the filter box is pushed into and pushed out of the groove along the notch. The notch on one side of the groove and the corresponding baffle form a channel when the baffle is flat, allowing the filter box to be easily pushed into or pushed out of the groove along the notch. This makes the operation simpler and faster when placing or removing dewatered metal scrap, improving work efficiency. When dewatering the metal scrap is required, the baffle can be rotated to stand upright, forming a relatively enclosed space with the groove, blocking water and scrap that may splash out during the squeezing process. The first handle on the side of the baffle away from the hinge provides a convenient point of leverage for the operator, making the operation of rotating the baffle more effortless and convenient, further enhancing the user-friendliness of the equipment operation.

[0010] Furthermore, in the metal waste dewatering and recycling device of this application, a pair of second handles are provided along the upper edge of the filter box. The pair of second handles along the upper edge of the filter box provide a stable and convenient gripping point for the operator.

[0011] Furthermore, in a metal scrap dewatering and recycling device of this application, a ball valve is provided on the water tank for draining the filtered water in the tank. The ball valve allows the operator to flexibly control the drainage time and speed according to the actual situation.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0013] 1. The metal waste dewatering and recycling device of this utility model has a reasonable dewatering component structure, including a frame, a moving platform, a motor, and an extrusion mechanism. The frame provides stable support, and the guide rails and guide columns ensure that the moving platform moves vertically and smoothly, so that the pressure block can accurately apply pressure to the metal waste. The pressure block is detachable and easy to replace. At the same time, the scissor structure and linkage mechanism of the extrusion mechanism can efficiently convert the motor power into the extrusion force on the metal waste. Compared with centrifugal dewatering equipment, the structure is simpler, the energy consumption is lower, and the operating cost is reduced.

[0014] 2. The metal waste dewatering and recycling device of this utility model improves work efficiency by setting baffles and notches in the groove to facilitate the loading and unloading of the filter box. At the same time, when the baffles are erected during dewatering, they can form a relatively closed space to prevent water and waste from splashing out, keep the working area clean, and optimize the working environment.
