Description

Technical Field

[0001] This utility model relates to an oil and shavings separation device for metal processing, belonging to the technical field of oil and shavings separation equipment. Background Technology

[0002] During the machining process, machine tools require coolant to cool the cutting tools and the workpieces. This results in metal shavings containing a large amount of coolant. To reduce environmental pollution and costs, and to facilitate the recycling of metal shavings, degreasing is necessary. To achieve continuous operation and improve separation efficiency, existing oil-shaving separators use a drive unit to rotate a drum. Metal shavings and coolant rise along the inner wall of the drum. The cutting fluid passes through a filter into the coolant collection area, while the metal shavings continue to rise and are thrown out through the opening of the drum. Due to the height of the drum... To ensure stable continuous operation, the rotation speed of the drum is also fixed during continuous operation. This results in a fixed separation time for metal shavings within the drum and a fixed time for them to pass through the filter screen. The longer the separation time within the drum, especially the longer the time spent passing through the filter screen, the better the separation effect. Existing oil shaving separators, with a fixed rotation speed, cannot adjust the separation time. Furthermore, since the metal shavings to be separated are fed in from the open end and discharged from the open end after separation, the two are prone to interference, affecting the separation efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an oil shavings separation device for metal processing, which can extend the separation time and reduce the interference between the metal shavings to be separated and the separated metal shavings under a fixed drum speed, thereby improving the separation effect and overcoming the shortcomings of the prior art.

[0004] The technical solution of this utility model is: an oil shavings separation device for metal processing, including a cylinder and a rotating drum driven by a drive mechanism inside the cylinder. A filter screen is installed inside the rotating drum, and a filtrate collection device is provided around the rotating drum. The device includes a lifting mechanism and a feeding device located above the rotating drum. The feeding device is coaxially distributed with the rotating drum. The feeding device has a feeding channel at its center, and its outer side cooperates with the inner wall of the rotating drum to form a discharge channel. The feeding device is driven to lift and adjust the distance between the outer side of the feeding device and the inner wall of the rotating drum by the lifting mechanism, thereby adjusting the size of the discharge channel.

[0005] Furthermore, the filter screen is in the form of a ring and is disposed on the inner wall of the drum, forming an interlayer between the filter screen and the drum. The drum is provided with a drain channel communicating with the interlayer, and the drain channel is connected to the filtrate collection device.

[0006] Furthermore, the drum includes a cooperating upper drum body and a lower drum body, which cooperate to form an annular groove and the drainage channel. The annular groove has a limiting mechanism, and the filter screen is installed in the annular groove in cooperation with the limiting mechanism to form the interlayer.

[0007] Furthermore, the upper drum body and the lower drum body are provided with matching flanges, and the upper drum body and the lower drum body are connected by the flanges, which are located on the outside of the interlayer.

[0008] Furthermore, the feeding device has a blocking member that rotates along its axis. When the feeding device is raised or lowered by a lifting mechanism to the position where the blocking member touches the inner wall of the drum, the discharge channel is closed.

[0009] Furthermore, when the blocking member contacts the inner wall of the drum, it is positioned above the filter screen, blocking the metal shavings to be discharged at the filter screen.

[0010] By implementing this utility model, the metal shavings to be separated fall into the drum from the center of the drum through the feeding channel of the feeding device. The driving mechanism drives the drum to rotate, and the metal shavings and coolant climb up the inner wall of the drum. The coolant is discharged at the filter screen and then enters the filtrate collection device. The separated metal shavings continue to climb and are discharged from the discharge channel formed by the outside of the feeding device and the inner wall of the drum. The feeding device separates the entry area of ​​the metal shavings to be separated from the discharge area of ​​the separated metal shavings, reducing interference. The discharge channel is the distance between the outside of the feeding device and the inner wall of the drum. The feeding device changes position by raising and lowering through the lifting device, so that the width of the distance between the outside of the feeding device and the inner wall of the drum (i.e., the discharge channel) changes. When the distance decreases or there is no distance, the discharge channel decreases or closes, thereby slowing down or blocking the continued climbing of the metal shavings. Without changing the rotation speed, the separation time of the metal shavings is increased, and the separation effect is improved. Attached Figure Description

Detailed Implementation

[0016] Embodiments of this utility model: such as Figures 1 to 4 As shown, a metalworking oil shavings separation device includes a cylinder 1 and a rotating drum 4 driven to rotate inside the cylinder 1 by a motor 3. The motor 3 is the driving mechanism. A filter screen 5 is installed inside the rotating drum 4, and a filtrate collection device is provided around the rotating drum 4. A cylinder 7 and a feeding device 8 driven to rise and fall by the cylinder 7 are provided on the cylinder 1. The feeding device 8 is coaxially distributed with the rotating drum 4. The feeding device 8 has a feeding channel 9 at its center. The distance between the outer side of the feeding device 8 and the inner wall of the rotating drum 4 forms a discharge channel 10 for the metal shavings after separation. The inner wall of the rotating drum 4 is flared, wider at the top and narrower at the bottom. The feeding device 8 is driven to rise and fall by the cylinder 7, which changes the distance between the feeding device 8 and the inner wall of the rotating drum 4, thereby adjusting the size of the discharge channel 10. In use, the metal shavings to be separated fall from the center of the rotating drum 4 through the feeding channel 9 of the feeding device 8. Inside the drum 4, the motor 3 drives the drum 4 to rotate. Metal shavings and coolant climb up the inner wall of the drum 4. After the coolant is discharged at the filter screen 5, it enters the filtrate collection device. The separated metal shavings continue to climb and are discharged from the discharge channel 10 between the outside of the feeding device 8 and the inner wall of the drum 4. After passing through the area between the cylinder 1 and the drum 4, they fall out and are discharged. The bottom of the feeding device 8 is located inside the drum 4, which separates the area where the metal shavings to be separated enter from the area where the separated metal shavings are discharged, reducing interference. The feeding device 8 is raised and lowered by the cylinder 7 to change its position. When the feeding device 8 descends, the distance between the outside of the feeding device 8 and the inner wall of the drum 4 (i.e., the discharge channel) becomes smaller. When the discharge channel is small or even completely closed, it slows down or blocks the continued climbing of the metal shavings, increasing the separation time of the metal shavings without changing the rotation speed, thereby improving the separation effect.

[0017] As a preferred embodiment, the filter screen 5 is in the form of a ring and is disposed on the inner wall of the drum 4, forming a sandwich 11 between the filter screen 5 and the drum 4. The drum 4 is provided with a drain channel 12 that communicates with the sandwich 11 and is connected to a filtrate collection device. If only mesh openings are made in the drum 4 to form a filter screen, the dense mesh openings will reduce the strength of the drum 4 itself in order to achieve better filtration effect. However, the structure of the present invention allows the separated coolant to enter the sandwich 11 through the filter screen 5 and then be discharged through the drain channel 12. Only the drain channel 12 needs to be made in the drum 4, which achieves efficient separation while maintaining good strength of the drum 4.

[0018] As a preferred embodiment, the drum 4 comprises a cooperating upper drum body 13 and a lower drum body 14, i.e., the drum adopts a detachable split structure. The upper drum body 13 and the lower drum body 14 cooperate to form an annular groove and a drainage channel 12. A limiting mechanism is provided within the annular groove, consisting of limiting slots located on the lower side of the upper drum body 13 and the upper side of the lower drum body 14. After the upper drum body 13 and the lower drum body 14 are engaged, the limiting slots are respectively within the annular groove. The filter screen 5 is connected and limited within the annular groove through the limiting slots on the upper and lower sides, and a sandwich 11 is formed between the filter screen 5 and the inner wall of the annular groove. This connection method ensures that the filter screen 5 and the inner wall of the drum 4 remain flat, allowing for... Metal shavings smoothly ascend through the filter screen 5, and can be easily disassembled and cleaned by separating the upper drum body 13 and the lower drum body 14. The upper drum body 13 and the lower drum body 14 are preferably connected by a flange 15. Since the upper drum body 13 and the lower drum body 14 form an annular groove after they are fitted together, the wall thickness at the connection between the upper drum body 13 and the lower drum body 14 becomes thinner. The flange 15 is located at the connection between the upper drum body 13 and the lower drum body 14, which strengthens the wall thickness at the annular groove. While facilitating the disassembly and cleaning of the filter screen 5, the filter screen 5 can remain flat with the inner wall of the rotating drum 4, and does not affect the separation and discharge of coolant or the strength of the rotating drum 4.

[0019] As a preferred embodiment, the feeding device 8 includes a feeding pipe 6 and a blocking member 16 connected to the feeding pipe via bearings. The feeding device adjusts the distance between the blocking member 16 and the inner wall of the drum 4 by raising and lowering the cylinder 7, thereby adjusting the size of the discharge channel 10. When the blocking member 16 is in contact with the inner wall of the drum 4, the discharge channel 10 is closed. At this time, the blocking member 16 is located above the filter screen 5, blocking the metal shavings at the filter screen 5 and preventing them from continuing to rise. The drum 4 drives the blocking member 16 and the blocked metal shavings to rotate together, thus preventing them from rising further. To prevent metal shavings from falling and allow them to rotate and separate at the filter screen 5 for an extended period, thus improving the oil shavings separation effect, the filtrate collection device includes a ring pipe 2 fixedly installed inside the cylinder 1. The ring pipe 2 has an annular opening, and a drain pipe 17 is connected to the bottom of the ring pipe 2. A flange 15 extends into the ring pipe 2 through the annular opening, and a discharge channel 10 is located at the flange 15. The separated coolant enters the ring pipe 2 through the discharge channel 10 and is then discharged through the drain pipe 17. When the cylinder 7 lifts the feeding device 8 to open the discharge channel 10, the separated metal shavings can be discharged.
