Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal waste treatment technology, specifically a metal waste spin dryer. Background Technology
[0002] In the machining industry, a lot of metal waste is generated during production, such as iron filings, aluminum filings, and copper filings. These metal wastes are usually compressed into patties using a metal hydraulic baler. However, these metal wastes often contain liquids such as cutting fluid, oil, or water, which cannot be processed by directly feeding them into the metal hydraulic baler and greatly affect the processing effect. Therefore, it is necessary to spin-dry these wastes.
[0003] In existing technologies, common centrifugal drying equipment is mostly a simple vibrating screen device. While these devices can achieve basic solid-liquid separation, they have significant drawbacks when handling adhering oil and water or fine metal scrap: First, their internal structure is usually quite simple, lacking an effective real-time flushing mechanism. This causes oil and metal fragments to easily clump and clog the screen openings and the inner walls of the equipment cavity, reducing dewatering efficiency and significantly increasing maintenance costs and time due to frequent shutdowns for cleaning. Second, most devices use a fixed top cover or a poorly sealed feed inlet design, making feeding and maintenance processes cumbersome and unable to quickly process large quantities or irregularly shaped waste. Furthermore, the drainage system is often poorly designed, resulting in the separated liquid mixing with tiny metal particles during discharge, affecting the purity of the recovered metal and increasing the difficulty of subsequent wastewater treatment. These shortcomings severely restrict the overall efficiency and economic benefits of the metal scrap centrifugal drying process. Utility Model Content
[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a metal scrap dryer, which integrates a real-time rinsing mechanism, an openable and closable sealed feed inlet, and a high-efficiency drainage system. This solves the technical problem in existing technologies where metal scrap containing liquids such as cutting fluid, oil, or moisture during compression and packaging is difficult to handle directly.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal scrap spin dryer, comprising a bottom support, a main unit mounted on the bottom support, a spin dryer chamber installed inside the main unit, and multiple fine holes distributed on the inner wall of the spin dryer chamber for discharging the liquid separated from the material; a feed hopper mounted on the top of the main unit, the outlet of the feed hopper facing the inlet of the spin dryer chamber for feeding metal scrap into the spin dryer chamber; the spin dryer chamber is driven to rotate by a power mechanism mounted on the bottom support; a drain outlet is installed on the other side of the main unit for discharging rinsing liquid and the liquid separated from the material; a discharge hopper is installed at the bottom of the main unit, and the metal scrap after spin drying falls from the upper edge of the spin dryer chamber, then falls along the inner wall of the main unit and the outer wall of the spin dryer chamber, and is finally discharged from the discharge hopper.
[0006] Furthermore, the power mechanism includes a drive motor mounted on the bottom bracket and located on one side of the main unit. A drive wheel is mounted on the output shaft of the drive motor. The power mechanism also includes a rotating shaft mounted on the lower end of the spin-drying chamber. A driven wheel is mounted on the lower end of the rotating shaft. A transmission belt is mounted between the drive wheel and the driven wheel. A bearing is also mounted on the rotating shaft.
[0007] Furthermore, springs are fitted at the four corners of the main unit and the bottom support assembly, and the springs are used to buffer the vibration of the metal waste spun dryer during spun drying.
[0008] Furthermore, the upper end of the host is provided with an openable top cover, and the feed hopper is installed in a mounting hole opened at the center of the top cover; the feed hopper can be opened or closed together with the top cover.
[0009] Furthermore, a rinsing head is installed on one side of the main unit. The rinsing head is connected to a water inlet pipe and is used to rinse the inside of the dryer during operation to prevent metal waste residue from clogging the fine holes and internal channels of the equipment.
[0010] Furthermore, the drain outlet is funnel-shaped, and a metal scrap recycling bin is installed below it.
[0011] Compared with the prior art, this utility model provides a metal waste centrifuge with the following advantages: 1. The drive structure consisting of a drive motor, drive wheel, driven wheel, and transmission belt enables stable high-speed rotation of the spin-drying chamber, significantly improving the spin-drying efficiency and dehydration uniformity of metal waste. The installation of the spring assembly effectively buffers vibration and impact during the spin-drying process, reduces noise levels, and minimizes equipment wear, thereby extending the overall service life and ensuring smooth operation.
[0012] 2. The openable and closable top cover, combined with the integrated installation of the feed hopper, facilitates users to quickly add waste materials and perform internal cleaning and maintenance of the equipment, improving operational convenience and safety.
[0013] 3. The flushing head is connected to the water inlet pipe, which can automatically flush the internal fine holes and channels during operation, effectively preventing the accumulation and blockage of metal residues, and ensuring the continuity of the spin-drying process and the reliability of the equipment.

[0015] 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.
[0016] Please see Figure 1This utility model provides a metal scrap spin dryer, including a bottom support 1. The spin dryer is characterized by: a main unit 2 mounted on the bottom support 1; a spin dryer 3 installed inside the main unit 2; multiple fine holes distributed on the inner wall of the spin dryer 3 for discharging the liquid separated from the material; a feed hopper 4 mounted on the top of the main unit 2, with its outlet facing the inlet of the spin dryer 3 for feeding metal scrap into the spin dryer 3; the spin dryer 3 is driven to rotate by a power mechanism 6 mounted on the bottom support 1; the power mechanism 6 includes a drive motor 601 mounted on the bottom support 1 and located on one side of the main unit 2, with a drive wheel 602 mounted on the output shaft of the drive motor 601; and a rotating shaft 603 mounted at the lower end of the spin dryer 3. A driven wheel 604 is fitted at the lower end of shaft 603, and a transmission belt 605 is fitted between the driving wheel 602 and the driven wheel 604. A bearing 606 is also fitted on the rotating shaft 603. A drain outlet 7 is installed on the other side of the main unit 2 to discharge the rinsing liquid and the liquid separated from the material. The drain outlet 7 is funnel-shaped, and a metal scrap recycling box is installed below it. A discharge hopper 8 is installed at the bottom of the main unit 2. The metal scrap after spin-drying falls from the upper edge of the spin-drying chamber 3, then falls along the inner wall of the main unit 2 and the outer wall of the spin-drying chamber 3, and is finally discharged from the discharge hopper 8. An openable top cover 10 is installed at the upper end of the main unit 2, and a feed hopper 4 is installed in the mounting hole opened at the center of the top cover 10. The feed hopper 4 can be opened or closed together with the top cover 10. Springs 9 are fitted on the four corners of the main unit 2 and the bottom support 1 assembly. The springs are used to buffer the vibration of the metal scrap spin dryer during spin-drying. A rinsing head 11 is installed on one side of the main unit 2. The rinsing head 11 is connected to the water inlet pipe and is used to rinse the inside of the dryer during operation to prevent metal waste residue from clogging the fine holes and internal channels of the equipment.
[0017] The working principle of the above embodiments is as follows: In operation, first open the top cover 10 and feed the metal scrap to be processed into the spin-drying chamber 3 through the feed hopper 4, then close the top cover 10. Start the drive motor 601, and power is transmitted to the driven wheel 604 through the drive wheel 602 and the transmission belt 605, driving the rotating shaft 603 and the spin-drying chamber 3 connected to it to rotate at high speed. Under the action of centrifugal force, cutting fluid, oil, or water in the scrap are forced through the fine holes in the inner wall of the spin-drying chamber 3 and separated from the solid metal scrap. The separated liquid flows downward along the inner wall of the main unit 2 channel and is discharged through the funnel-shaped drain 7 to a designated collection point or treatment system, effectively preventing liquid splashing. At the same time, during operation, an external water source can be connected through the flushing head 11 to continuously or intermittently inject flushing water into the main unit 2 to promptly remove any residue that may adhere to the fine holes of the spin-drying chamber 3 or the inner wall channel of the main unit 2, ensuring separation efficiency and smooth equipment operation.
[0018] Once the aforementioned spin-drying and dehydration process is complete, the dehydrated metal scrap, due to rotational inertia and gravity, is ejected from the top edge of the spin-drying chamber 3, then falls along the channel between the inner wall of the main unit 2 and the outer wall of the spin-drying chamber 3, and finally exits through the bottom discharge hopper 8, falling into the pre-placed metal scrap recycling bin. Throughout the entire spin-drying and unloading process, the springs 9 fitted at the four corners of the connection between the main unit 2 and the bottom support 1 continuously buffer the vibrations caused by the high-speed rotation of the rotating parts and uneven material distribution, significantly improving the stability of the equipment operation, reducing noise, and extending the service life of key components.
