Description

Technical Field

[0001] The utility model relates to the field of cooling liquid recovery devices for water mill machine tools, and in particular to a cooling liquid recovery device for water mill machine tools. Background Art

[0002] A water-polished surface typically refers to the smooth, flat surface achieved by a water-based grinding machine. A water-based grinding machine is a water-cooled machine tool that immerses the grinding head in water, utilizing the cooling and lubricating properties of the water to reduce heat and wear during grinding, thereby ensuring precision and efficiency. The water cooling also flushes away metal shavings generated during the grinding process, maintaining a clean and smooth surface.

[0003] When existing water mills recycle waste liquid, they usually adsorb metals through permanent magnets, that is, the wastewater flows through the permanent magnets to adsorb the metals. The metal adsorption effect is affected by factors such as the installation position and water flow. The existing technology directly passes the wastewater to the permanent magnet, which is prone to poor metal adsorption due to excessive and concentrated water flow. It also requires frequent cleaning of the metal adsorbed on the permanent magnet, which is inconvenient to use. Utility Model Content

[0004] In view of this, the utility model provides a coolant recovery device for a water mill machine tool, which can effectively improve the metal debris adsorption rate.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A coolant recovery device for a water grinding machine tool comprises: a collection box, a liquid inlet pipe arranged on the top of the collection box, and a chip removal mechanism arranged inside the collection box; a conical diversion block is provided at the bottom inner side of the liquid inlet pipe, and a liquid outlet extending in a circular arc is provided on the circumferential side of the liquid inlet pipe; the chip removal mechanism comprises a conical magnetic plate located below the liquid inlet pipe, a scraper rotatably arranged on the upper surface of the magnetic plate, and a drive assembly, the central axis of the magnetic plate coincides with the central axis of the diversion block, the magnetic plate is provided with a fan-shaped notch offset from the liquid outlet, and the drive assembly is used to drive the scraper to perform circular motion around the central axis of the magnetic plate.

[0007] In the above technical solution, waste liquid generated during the water milling process flows into the liquid inlet pipe and is evenly dispersed by the diverter block, reducing impact force and turbulence. The dispersed waste liquid then flows evenly from the liquid outlet and falls onto the upper surface of the magnetic plate. As the waste liquid flows over the upper surface of the magnetic plate, metal debris is absorbed by the magnetic plate, significantly reducing the metal content in the waste liquid. In addition, the drive assembly drives the scraper to rotate, allowing it to scrape the metal absorbed on the upper surface of the magnetic plate and concentrate the metal in the fan-shaped notch, thereby completing the collection of metal debris.

[0008] Therefore, the utility model can effectively control the water flow through the design of the conical diverter block and the magnetic plate, so that the water flows through the magnetic plate at a gentle and shallow depth. The magnetic plate can more effectively absorb metal impurities such as iron filings in the coolant, and the scraper moves in a circular motion around the central axis of the magnetic plate under the action of the driving component, ensuring the cleanliness of the surface of the magnetic plate and avoiding the accumulation of impurities, thereby improving the chip removal efficiency and ensuring the quality of the recovered coolant.

[0009] Optionally, in a possible implementation, the driving assembly includes a motor and a shaft block, the motor is located below the magnetic plate, and the output shaft of the motor passes through the magnetic plate and is connected to the shaft block, and the scraper is connected to the shaft block.

[0010] In this technical solution, the motor directly drives the shaft block and scraper, eliminating intermediate transmission links, improving power transmission efficiency, and reducing energy loss, allowing the scraper to respond more stably and quickly to the motor's rotation. Furthermore, placing the motor below the magnetic plate and directly connecting the shaft block and scraper via an output shaft makes the entire drive assembly compact, easily integrating with the collection box and other components, and reducing installation and maintenance complexity.

[0011] Optionally, in a possible implementation, the magnetic plate is installed in the collection box via a bracket, and the driving assembly is installed on the bracket.

[0012] In this technical solution, the magnetic plate is mounted inside the collection box via a bracket, ensuring stability and reliability during chip removal. The drive assembly is also mounted on the bracket, ensuring a secure fit for components like the motor and shaft block, preventing malfunctions caused by vibration or impact.

[0013] Optionally, in a possible implementation, a detachable material storage box is provided on the bracket, and the material storage box is located directly below the fan-shaped notch.

[0014] In the above technical solution, the storage box is located directly below the fan-shaped notch, which can efficiently collect metal debris and other impurities that fall off the magnetic plate, making the waste collection process more convenient, preventing waste from being scattered or left in the collection box, and reducing the workload and time of cleaning. At the same time, the detachable storage box facilitates the centralized processing of waste and facilitates the timely removal of waste from the storage box.

[0015] Optionally, in a possible implementation, the bracket includes a plurality of support rods and a connecting plate fixed on the plurality of support rods, and the driving assembly and the storage box are both mounted on the connecting plate.

[0016] In the above technical solution, the bracket composed of multiple support rods and connecting plates provides sufficient support and stability, ensuring that the magnetic plate, drive assembly and storage box can always remain stable during the operation of the equipment, and the connection method is simple and clear, which is convenient for assembly and disassembly.

[0017] Optionally, in a possible implementation, a rubber strip is provided on the scraper, the rubber strip is located between the scraper and the magnetic plate, and the rubber strip abuts against the upper surface of the magnetic plate.

[0018] In the above technical solution, the rubber strip design reduces the gap between the scraper and the magnetic plate, increasing the contact area and friction between the scraper and the magnetic plate, allowing the scraper to more effectively remove metal debris and other impurities attached to the magnetic plate during rotation. Furthermore, the rubber strip acts as a buffer layer between the scraper and the magnetic plate, reducing direct friction and wear on the magnetic plate surface.

[0019] Optionally, in a possible implementation, the magnetic plate includes a magnetic portion with magnetism and a non-magnetic portion without magnetism, and there are one or two non-magnetic portions. The non-magnetic portions are located on one side or both sides of the edge of the fan-shaped gap and are used to separate the magnetic portion and the fan-shaped gap.

[0020] In the above technical solution, the design of the non-magnetic part can make it easier for the scraper to scrape off the metal debris. When the scraper rotates along the surface of the magnetic plate, it will synchronously scrape the metal debris attached to the surface of the magnetic plate and drive the metal debris to move synchronously until it enters the non-magnetic part. At this time, the metal debris is separated from the magnetic part and will not be affected by its adsorption force. It can fall from the fan-shaped notch more conveniently without being adsorbed on its edge.

[0021] Optionally, in a possible implementation, a slow flow box is further included, which is located at the outer top of the collecting box, is connected to the liquid inlet pipe, and a plurality of liquid inlet holes are provided at the connection between the slow flow box and the liquid inlet pipe, and the slow flow box is also connected to a liquid receiving pipe.

[0022] In the above technical solution, the design of the slow-flow box allows the coolant to pass through a buffer area before entering the collection tank. The coolant enters the slow-flow box through multiple inlet holes in a uniform distribution, slowing the coolant flow rate and streamlining the flow path. This allows the coolant to fall more smoothly onto the magnetic plate, further improving the magnetic plate's adsorption effect on the metal.

[0023] Optionally, in a possible implementation, a liquid outlet pipe is provided at the bottom of the collection box, and a control valve is connected to the liquid outlet pipe.

[0024] In the above technical solution, the arrangement of the outlet pipe and control valve allows for easy drainage and cleaning of the coolant in the collection tank. When the coolant in the collection tank reaches a certain volume or needs to be replaced, the operator simply closes the control valve and disconnects the outlet pipe from the subsequent processing equipment to clean and maintain the collection tank, thereby improving equipment maintenance efficiency and management convenience.

DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0032] Please refer to Figure 1The present embodiment provides a coolant recovery device for a water mill, comprising: a collection box 1, a liquid inlet pipe 2 arranged at the top of the collection box 1, and a chip removal mechanism 3 arranged inside the collection box 1; a conical diversion block 4 is provided at the inner bottom of the liquid inlet pipe 2, and a liquid outlet 21 extending in a circular arc is provided on the circumferential side of the liquid inlet pipe 2; the chip removal mechanism 3 comprises a conical magnetic plate 31 located below the liquid inlet pipe 2, a scraper 32 rotatably arranged on the upper surface of the magnetic plate 31, and a driving component 33, the central axis of the magnetic plate 31 coincides with the central axis of the diversion block 4, the magnetic plate 31 is provided with a fan-shaped notch 34 which is offset from the liquid outlet 21, and the driving component 33 is used to drive the scraper 32 to perform a circular motion around the central axis of the magnetic plate 31. Specifically, the liquid inlet pipe 2 is fixed to the top of the collection box 1, with one end extending outside the collection box 1 and the other end located inside the collection box 1. It is a bottom-sealed structure. The liquid outlet 21 is located on the outer periphery of the liquid inlet pipe 2 and extends along the circumference of the liquid inlet pipe 2. The waste liquid flowing out of the liquid outlet 21 can fall onto the magnetic plate 31 instead of falling into the fan-shaped notch 34.

[0033] The waste liquid generated during the water mill machining process flows into the liquid inlet pipe 2 and is evenly dispersed by the diverter block 4, reducing impact force and turbulence. The dispersed waste liquid flows evenly from the liquid outlet 21 and falls smoothly onto the upper surface of the magnetic plate 31. As the waste liquid flows over the upper surface of the magnetic plate 31, metal debris is absorbed by the magnetic plate 31, thereby greatly reducing the metal content in the waste liquid. In addition, the drive assembly 33 drives the scraper 32 to rotate, so that the scraper 32 can scrape the metal absorbed on the upper surface of the magnetic plate 31 and concentrate the metal in the fan-shaped notch 34, thereby completing the collection of metal debris.

[0034] This embodiment can effectively control the water flow through the design of the conical diverter block 4 and the magnetic plate 31, so that the water flows through the magnetic plate 31 at a gentle and shallow depth. The magnetic plate 31 can more effectively absorb metal impurities such as iron filings in the coolant, and the scraper 32 moves in a circular motion around the central axis of the magnetic plate 31 under the action of the drive component 33, ensuring the cleanliness of the surface of the magnetic plate 31 and avoiding the accumulation of impurities, thereby improving the chip removal efficiency and ensuring the quality of the recovered coolant.

[0035] In this embodiment, the drive assembly 33 includes a motor 331 and a shaft block 332. The motor 331 is located below the magnetic plate 31, and the output shaft of the motor 331 passes through the magnetic plate 31 and is connected to the shaft block 332. The scraper 32 is connected to one side of the shaft block 332. The shaft block 332 is rotatably mounted on the magnetic plate 31 via a bearing or other structure, that is, the shaft block 332 is supported by the bearing.

[0036] The motor 331 directly drives the shaft block 332 and scraper 32 to rotate, eliminating intermediate transmission links, improving power transmission efficiency, and reducing energy loss. This allows the scraper 32 to respond more stably and quickly to the rotation of the motor 331. Furthermore, placing the motor 331 below the magnetic plate 31 and directly connecting the shaft block 332 and scraper 32 via an output shaft makes the entire drive assembly 33 compact, easily integrating with the collection box 1 and other components, and reducing the complexity of installation and maintenance.

[0037] In this embodiment, the magnetic plate 31 is mounted within the collection box 1 via a bracket 5, and the drive assembly 33 is mounted on the bracket 5. The bracket 5 supports the bottom of the magnetic plate 31, ensuring its stability and reliability during the chip removal process. The drive assembly 33 is also mounted on the bracket 5, ensuring the secure mounting of components such as the motor 331 and the shaft block 332, preventing malfunctions due to vibration or impact.

[0038] In this embodiment, a detachable storage box 6 is provided on the bracket 5 and is located directly below the sector-shaped notch 34. The storage box 6 located directly below the sector-shaped notch 34 can efficiently collect metal debris and other impurities that fall off the magnetic plate 31, making the waste collection process more convenient, preventing waste from being scattered or left in the collection box 1, and reducing the workload and time of cleaning. Furthermore, the detachable storage box 6 facilitates centralized waste processing and facilitates timely cleaning of the waste in the storage box 6.

[0039] It should be noted that the bracket 5 includes multiple support rods 51 and a connecting plate 52 fixed to the multiple support rods 51. The drive assembly 33 and the storage box 6 are both mounted on the connecting plate 52. The storage box 6 can be mounted on the bracket 5 by means of a snap connection, adhesive bonding, or screw connection. The bracket 5, consisting of the multiple support rods 51 and the connecting plate 52, provides sufficient support and stability, ensuring that the magnetic plate 31, the drive assembly 33, and the storage box 6 remain stable during operation of the device. The simple and clear connection method facilitates assembly and disassembly.

[0040] In this embodiment, a rubber strip 321 is provided on the scraper 32. The rubber strip 321 is located between the scraper 32 and the magnetic plate 31, and the rubber strip 321 abuts the upper surface of the magnetic plate 31. The design of the rubber strip 321 reduces the gap between the scraper 32 and the magnetic plate 31, thereby increasing the contact area and friction between the scraper 32 and the magnetic plate 31. This allows the scraper 32 to more effectively scrape away metal debris and other impurities adhering to the magnetic plate 31 during rotation. Furthermore, the rubber strip 321 acts as a buffer layer between the scraper 32 and the magnetic plate 31, reducing direct friction and wear on the surface of the magnetic plate 31 caused by the scraper 32.

[0041] The magnetic plate 31 of this embodiment includes a magnetic portion 311 with magnetism and a non-magnetic portion 312 without magnetism. There are one or two non-magnetic portions 312 . The non-magnetic portions 312 are located on one side or both sides of the edge of the fan-shaped notch 34 and are used to separate the magnetic portion 311 and the fan-shaped notch 34 .

[0042] The design of the non-magnetic part 312 can make it easier for the scraper 32 to scrape off the metal debris. When the scraper 32 rotates along the surface of the magnetic plate 31, it will synchronously scrape the metal debris attached to the surface of the magnetic plate 31 and drive the metal debris to move synchronously until it enters the non-magnetic part 312. At this time, the metal debris is separated from the magnetic part and will not be affected by its adsorption force. It can more easily fall from the fan-shaped notch 34 without being adsorbed on its edge.

[0043] The recovery device of this embodiment also includes a slow flow box 7, which is located at the outer top of the collection box 1. The slow flow box 7 is connected to the liquid inlet pipe 2, and a plurality of liquid inlet holes 71 are provided at the connection between the slow flow box 7 and the liquid inlet pipe 2. The slow flow box 7 is also connected to the liquid receiving pipe 8.

[0044] The design of the slow flow box 7 allows the coolant to pass through a buffer area before entering the collection box 1. The coolant enters the slow flow box 7 through multiple liquid inlet holes 71 in a uniform distribution, slowing down the flow rate of the coolant and optimizing the flow path of the coolant, allowing the coolant to fall more smoothly onto the magnetic plate 31, further improving the magnetic plate 31's adsorption effect on the metal.

[0045] In this embodiment, a liquid outlet pipe 9 is provided at the bottom of the collection tank 1, connected to a control valve. This arrangement of the liquid outlet pipe 9 and the control valve facilitates the discharge and cleaning of the coolant within the collection tank 1. When the coolant in the collection tank 1 reaches a certain volume or requires replacement, the operator simply closes the control valve and disconnects the liquid outlet pipe 9 from subsequent processing equipment to clean and maintain the collection tank 1, thereby improving maintenance efficiency and ease of management.
