A water-saving chip degreasing and cleaning machine

Abstract

The invention relates to a water-saving chip degreasing and cleaning machine; the technical solution is to arrange a feed pipe and an extension pipe on a water tank so that the liquid level is placed at the lower end of the extension pipe without pressurization. After the material to be cleaned is put into the feed pipe, the liquid level rises, and the feed pipe is free of water by pressurization. At this time, the liquid level in the feed pipe reaches its lowermost end, and the cleaned oil floats to the extension pipe at a higher position under the action of oil-water separation, so that there is no or only a thin layer of oil film at the lower end of the feed pipe, and the remaining oil film is destroyed by continuous inflation before pressure relief. At this time, when discharging, the water in the water tank enters the feed pipe, and no oil film is generated in the degreasing pipe, so that the problem of secondary pollution of the oil film will not be caused when discharging.

Description

Technical Field

[0001] The invention relates to the field of machining, in particular to a water-saving cutting chip degreasing and cleaning machine. Background Art

[0002] Machining, especially turning and milling, will generate a large amount of cutting chips. In order to cool and lubricate the tool and prevent the chips from adhering to the tool during machining, it is usually necessary to use coolant, lubricating oil and other grease-based liquid spraying during workpiece processing. Most of these liquids can be directly recycled during processing, but a large part of them still adhere to the cutting chips. Therefore, the cutting chips need to be cleaned and briquetted after collection before they can be returned to the furnace. Uncleaned cutting chips will not only affect the briquetting of the cutting chips, but also produce a large amount of toxic and harmful gases when they are returned to the furnace for recasting, greatly increasing the cost of subsequent environmental protection treatment.

[0003] At present, the chip degreasing and cleaning generally adopts the immersion cleaning method. The chips with oil are poured into a box filled with clean water and a cleaning agent is added. Through the effect of oil-water separation, the grease substances float on the upper layer of the box. Water is continuously injected to allow the grease above the water tank to be washed away with the water flow, and then the cleaned chips are salvaged from the water tank. This method requires a large amount of water to be injected into the water tank during cleaning so that the cleaned chips can be salvaged only after the upper oil is washed away. If the oil is not cleaned on the water surface, directly salvaging the cleaned chips will cause the oil to be re-wrapped on the cleaned chips, causing secondary pollution of the chips. However, continuous water injection, large industrial water consumption and high sewage treatment costs are not conducive to current production needs. In addition, traditional chip cleaning also has the problem of inconvenience in salvaging after cleaning.

[0004] The application number is 202010295780.2, and the patent name is: A device for removing iron chips and removing chip oil stains during lathe turning. It provides a device for cleaning chips by oil-water separation. The device sinks the chips into the water in the water tank to achieve oil-water separation, and moves the chips to the chip storage box in the water and seals them. To remove the chips, the device needs to drain the water in the water tank before the chips in the chip storage box connected to the water tank can be removed. In this process, more water is required to complete a cleaning and material removal, and the water consumption and pollution are more serious. Therefore, at this stage, a new chip cleaning equipment is urgently needed to solve the problem of large water volume. Summary of the invention

[0033] In order to facilitate feedback of the pressure control effect, the feed pipe 2 is provided with a transparent window along its length direction, and the water tank 1 is provided with a window for convenient observation of the feed pipe 2.

[0034] In order to achieve stable operation of the components of the device, the first electric cylinder 10, the second electric cylinder 11 and the third electric cylinder 16 are all waterproof electric cylinders.

[0035] To facilitate the use of the device, a lifting ring is provided at the upper end of the first electric cylinder 10, and water inlet and outlet are provided vertically. A valve is provided on the inlet and outlet pipes. A feed port is provided on the bottom of one of the second filter cartridges 12, and a detachable cartridge cover is provided on the feed port. The corresponding second gear 13 is installed on the cartridge cover. The first filter cartridge 7 and the second filter cartridge 12 are hard filter cartridges, and the filter cartridges filter water through water-permeable holes. The inner wall of the water tank 1, the extension tube 4 and the inner wall of the feed pipe 2 are coated with an oleophobic coating.

[0036] The specific working process of the present invention is as follows: before use, water is poured into the water tank 1, the amount of water poured exceeds the maximum water capacity of the water tank 1, and the liquid level is placed at about a quarter of the position near the bottom of the extension tube 4. At this time, the feed tube 2 and the extension tube 4 are in a U-shaped tube structure, and the second filter cartridge 12 is placed near the sleeve 8. At this time, the first filter cartridge 7 and the second filter cartridge 12 are in a contracted state, and the coil spring 15 is reset so that the U-shaped rod 14 limits the bottom of the second filter cartridge 12. Here, due to the hinged position of the U-shaped rod 14, when the U-shaped rod 14 is pulled by gravity to be parallel to the axis of the first filter cartridge 7, the limiting effect can still be effectively achieved, and the material holding device is lifted by the lifting device and passed through the second The waterproof motor drives the drive chain formed by the first sprocket 19 and the second sprocket 20 to realize the rotation of the sleeve 8. In this process, the second filter cartridge 12 with a removable cartridge cover is facing upward, and the cutting chips to be cleaned are fed into the first filter cartridge 7 and the second filter cartridge 12 in a retracted state through the feeding equipment. When feeding, the second filter cartridge 12 can be kept tilted for easy feeding. After the feeding is completed, the cartridge cover is closed and the drive chain is used to keep the first filter cartridge 7 and the second filter cartridge 12 with vertical axes, the second electric cylinder 11 is controlled to remain retracted, and the material holding equipment is fed from the feeding pipe 2 so that the first filter cartridge 7 and the second filter cartridge 12 are completely placed in the water tank 1. At this time, the fourth electric cylinder 17 in the water tank 1 is in a retracted state.

[0037] After the loading equipment is hoisted into the feed pipe 2, ensure that the first filter cartridge 7 and the second filter cartridge 12 are placed in the water tank 1. At this time, the liquid levels in the extension tube 4 and the feed pipe 2 rise, and the upper end of the first electric cylinder 10 and the second electric cylinder 11 are placed in the feed pipe 2. By controlling the second electric cylinder 11 to extend, the second electric cylinder 11 fixes the first electric cylinder 10 in the feed pipe 2. At this time, the hoisting equipment is removed, and the second waterproof motor controls the drive chain to realize the rotation of the first filter cartridge 7 and the second filter cartridge 12, which were originally in the vertical state of the main line, to the horizontal axis. After completion, the fourth electric cylinder 17 is controlled to extend and drive the vertical rod 5 and the first gear 6 to move closer to the middle until the vertical rod 5 is placed directly below the corresponding pad 18 and the bottom of the second filter cartridge 12. After completion, the first electric cylinder 10 extends to drive the first filter cartridge 7 and the second filter cartridge 12 downward until the second gear 13 is placed on the two first gears 6 and is driven by the first gear 6 The U-shaped rod 14 is driven by the push rod 21 to rotate around its hinged position, and the coil spring 15 is stretched and stressed, so that the bottom rod of the U-shaped rod 14 is away from the bottom of the second filter cartridge 12, and the U-shaped rod 14 no longer restrains the second filter cartridge 12. At this time, the fourth electric cylinder 17 is driven to retract, and the upper end of the vertical rod 5 squeezes the driving pad 18 to pull the second filter cartridge 12 out of the first filter cartridge 7. At this time, the first filter cartridge 7 and the second filter cartridge 12 are extended and kept rotating under the drive of the first gear 6. After completion, the hatch 3 at the upper end of the feed pipe 2 is closed, and the feed pipe 2 is pressurized by the high-pressure air source to drain the water in the feed pipe 2. At this time, the liquid level in the feed pipe 2 is at the lower end surface of the feed pipe 2, and the oil and dirt cleaned in the rotating first filter cartridge 7 and the second filter cartridge 12 float upward through oil-water separation in the water tank 1, and will eventually gather in the upper layer of the extension pipe 4.

[0038] After cleaning is completed, the fourth electric cylinder 17 is driven to retract, and the upper end of the vertical rod 5 squeezes and drives the bottom of the second filter cartridge 12 to make the second filter cartridge 12 slide toward the first filter cartridge 7. During this process, the first gear 6 should be kept to continuously drive the second gear 13 to rotate in order to effectively realize the gathering of cutting chips. When the second filter cartridge 12 is reset, the third electric cylinder 16 is controlled to extend, and under the reset action of the coil spring 15, the bottom rod of the U-shaped rod 14 is again limited with the bottom of the second filter cartridge 12. At this time, the first electric cylinder 10 is controlled to retract, the first filter cartridge 7 and the second filter cartridge 12 are lifted, and the fourth electric cylinder 17 is controlled to reset. At this time, the gas is supplied from the lower end of the feed pipe 2 through the high-pressure gas source so that the gas enters the water tank 1, and a very thin oil film formed at the lower end of the feed pipe 2 under the action of the water tension is broken. After the oil film is broken by the bubbles, it floats to the upper end of the extension tube 4 with the buoyancy. At this time, There is no oil film at the lower end of the feed pipe 2. The second waterproof motor drives the drive chain to drive the first filter cartridge 7 and the second filter cartridge 12 to rotate from horizontal to vertical, and the hatch of the feed pipe 2 is opened, so that the pressure on the upper end of the feed pipe 2 disappears. Under the action of the U-shaped tube structure, the liquid level in the feed pipe 2 rises, and the liquid level in the extension tube 4 drops. At this time, the liquid level in the feed pipe 2 enters from the water tank 1 and does not contain oil. When the liquid level in the extension tube 4 drops, the lower layer of oil-free water flows back into the water tank 1. At this time, the lifting equipment is fixed on the lifting ring, and the second electric cylinder 11 is controlled to retract and release the feed pipe 2, and then the material holding equipment is lifted out of the feed pipe 2. The cleaned chips are poured out by opening the barrel cover, and new chips to be cleaned are filled to repeat the above operation for cleaning. When too much oil accumulates in the extension tube 4, water can be injected into the water tank 1 to achieve the floating of the excess oil layer out of the extension tube 4 for degreasing.

[0039] Compared with traditional equipment, this device has the following advantages:

[0040] 1. The device arranges a feed pipe 2 and an extension pipe 4 on a water tank 1 so that the liquid level is located at the lower end of the extension pipe 4 without pressurization. After the cleaned material is added from the feed pipe 2, the liquid level rises, and the feed pipe 2 is free of water by pressurization. At this time, the liquid level in the feed pipe 2 reaches its lowest end, and the cleaned oil floats to the extension pipe 4 at a higher position under the action of oil-water separation, so that there is no or only a thin layer of oil film at the lower end of the feed pipe 2. Before the pressure is released, the air is continuously inflated to destroy the remaining oil film. At this time, when discharging the material, the water in the water tank 1 enters the feed pipe 2, and no oil film is generated in the feed pipe 2. Therefore, the problem of secondary pollution of the oil film will not be caused when discharging the material.

[0041] 2. When loading, the first filter cartridge 7 and the second filter cartridge 12 of the holding equipment of the device shrink, and the volume of the first filter cartridge 7 and the second filter cartridge 12 is reduced, so more material can be loaded into the cavity with the reduced volume. In the water tank 1, the first filter cartridge 7 and the second filter cartridge 12 are pulled apart, and the material is dispersed in the enlarged cavity. At this time, the rotating first filter cartridge 7 and the second filter cartridge 12 can effectively make the cuttings inside them contact with the cleaning water and be cleaned. The cavity formed by the first filter cartridge 7 and the second filter cartridge 12 can be changed, which can realize convenient operation during feeding. During rotation cleaning, it can be ensured that the cuttings are not loose and have enough rotation cleaning space, so the cleaning is more efficient and thorough, and the transportation of fillers is faster and more efficient.

[0042] 3. The oil layer in the device gathers at the upper end of the extension tube 4. The diameter of the extension tube 4 is smaller than the diameter of the water tank 1. Therefore, when draining the oil, a small amount of water can be injected to increase the liquid level in the extension tube 4, thereby achieving rapid oil drainage, so that the entire oil drainage process saves more water, thereby reducing water consumption and sewage treatment volume.
