Description

Technical Field

[0001] This invention relates to the field of oil-water separation technology, and more specifically, to a vertical synchronous belt drive type oil-water separation device for machine tools. Background Technology

[0002] Oil-water separation is a technology that uses the density difference or chemical property difference between water and oil to achieve oil-water separation by gravity sedimentation or other physicochemical reactions. The main methods include gravity separation, centrifugal separation, electrostatic separation, adsorption separation and air flotation separation. Gravity separation is based on Stokes' law and improves separation efficiency by increasing the sedimentation area or increasing the sedimentation rate of water.

[0003] Among the common types of oil-water separators, belt-type oil-water separators typically only have an oil scraping structure on one side of the belt. After the belt absorbs the floating oil, it is only scraped once before being re-immersed in the cutting fluid for recycling. The other side of the belt lacks active oil scraping treatment for a long time. Since both sides of the belt come into contact with oil during operation, scraping oil from only one side means that the oil film attached to the other side cannot be effectively removed. This residual grease gradually desorbs as the belt re-enters the cutting fluid, causing the separated oil to mix into the cutting fluid again. This directly reduces the efficiency of oil-water separation and the purity of the recovered oil. At the same time, the long-term accumulation of residual oil film on the belt surface will also accelerate the aging of the belt material. Summary of the Invention

[0004] This invention provides a vertical synchronous belt drive machine tool oil-water separation device. By setting up a diversion device and a cleaning device, it improves the oil recovery efficiency and equipment operation stability. The oil guide plate guides the grease scraped off by the scraper to the grease collection container. The baffle plate prevents oil droplets from splashing during the operation of the conveyor belt and guides the residual grease adhering to the belt surface to the collection plate. The spring set between the baffle plate and the placement block gives it elastic floating ability, which can adapt to the slight vibration or deviation of the conveyor belt. This solves the problems mentioned in the background art, namely: the residual grease gradually desorbs after re-entering the cutting fluid with the belt, causing the separated oil to mix into the cutting fluid again, directly reducing the oil-water separation efficiency and the purity of the recovered oil. At the same time, the long-term accumulation of residual oil film on the belt surface will also accelerate the aging of the belt material.

[0005] To achieve the above objectives, a vertical synchronous belt drive machine tool oil-water separation device includes a housing and a reducer. The reducer is located on one side of the housing, and a motor is fixedly installed on the outside of the reducer. A mounting flange is fixedly installed on one side of the housing, and one side of the mounting flange is detachably connected to the motor. A drive wheel is fixedly connected to the output end of the reducer, and a driven wheel is provided at the bottom of the drive wheel. A conveyor belt is externally connected to the drive wheel and the driven wheel. An oil scraper is fixedly connected inside the housing and is located on one side of the conveyor belt. An oil guide plate is fixedly connected to the outside of the housing near the oil scraper.

[0006] The box is equipped with a diversion device, which includes a storage plate inside the box. Connecting blocks are fixedly connected to both sides inside the storage plate. A placement block is fixedly connected to the top of the connecting blocks. A baffle plate is slidably connected inside the two placement blocks. The baffle plate is located on one side of the conveyor belt.

[0007] In the above technical solution, a sealing frame is fixedly connected inside the box, and the inside of the sealing frame is rotatably engaged with the outside of the drive wheel. A base plate is fixedly installed on the outside of the bottom end of the box. The conveyor belt is made of PU polyurethane material, and the inside of the base plate is rotatably engaged with the outside of the driven wheel. The oil scraper is made of polyurethane board.

[0008] Secondly, a conveyor plate is detachably connected to the outside of the storage plate. Two fixing blocks are fixedly connected to the bottom of the conveyor plate. The two fixing blocks are detachably connected to the housing by bolts. A guide groove is opened inside the storage plate. A diverter plate is fixedly connected inside the storage plate. When the scraped grease flows, the grease flows inside the guide groove and some of the grease will contact the diverter plate. The diverter plate guides the grease to both sides inside the storage plate, so that the grease flows into the conveyor plate. Springs are fixedly connected to both sides inside the placement block and both sides of the baffle plate. The bottom end of the baffle plate near the conveyor belt has an inclined surface for guiding the grease.

[0009] Furthermore, based on the above, a cleaning device is provided inside the box. The cleaning device includes two storage boxes inside the box, which are located on both sides of the conveyor belt. Two support blocks are fixedly connected to the top of the storage boxes. Cleaning rollers are rotatably connected to the ends of the two support blocks that are close to each other. The two cleaning rollers are located on both sides of the conveyor belt. A scraper is fixedly connected to the top of the storage plate. The scraper is a wire brush and is located at the bottom of the cleaning rollers. A collection cavity is provided inside the storage box.

[0010] Meanwhile, a sealing plate is fixedly connected to one side of each of the two storage boxes, and a positioning block is fixedly connected to the outside of the box near the sealing plate. The outside of the positioning block is slidably connected to the inside of the sealing plate, and a threaded post is threadedly connected to the inside of the positioning block. A pressing plate is rotatably connected to one side of the threaded post. The pressing plate is located on one side of the sealing plate, and the outside of the pressing plate is slidably connected to the inside of the positioning block.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] In this vertical synchronous belt drive machine tool oil-water separation device, a diversion device and a cleaning device are installed to improve oil recovery efficiency and equipment operation stability. The oil guide plate guides the grease scraped off by the scraper to the grease collection container. The baffle plate prevents oil droplets from splashing during the operation of the conveyor belt. At the same time, it guides the residual grease adhering to the other side of the belt to the collection plate for discharge, achieving double-sided oil scraping of the conveyor belt. The spring between the baffle plate and the placement block gives it elastic floating ability, which can adapt to the slight vibration or deviation of the conveyor belt. The cleaning roller continuously brushes the surface of the conveyor belt to remove adsorbed floating matter. Fine chips and dust particles mixed in during the oiling process are collected in a collection chamber inside the storage box. A fixed scraper on the top of the storage box can remove dirt adhering to the surface of the cleaning roller. A sealing plate on one side of the storage box slides in conjunction with the positioning block on the outside of the box. The screw column drives the extrusion plate to lock or release laterally, so that the storage box can be pulled out for cleaning without disassembling the box. The PU polyurethane conveyor belt is used to absorb floating oil, and the oil scraper of the same material works in conjunction with it to ensure the oil scraping effect while avoiding excessive wear on the working surface of the conveyor belt and extending the service life of the transmission system.

[0025] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0026] Since most scraper blades are fixed installations, the contact pressure is not adjustable. If the pressure is too low, the oil stains will not be completely removed, and if the pressure is too high, the conveyor belt will wear out.

[0027] Therefore, in view of the above-mentioned problems, the present invention provides a vertical synchronous belt drive type machine tool oil-water separation device, referencing... Figure 1 , Figure 2 and Figure 7As shown, the device includes a housing 1 and a reducer 2. The reducer 2 is located on one side of the housing 1. A motor 3 is fixedly installed on the outside of the reducer 2. A mounting flange 4 is fixedly installed on one side of the housing 1. The mounting flange 4 and the motor 3 are detachably connected on one side, allowing the motor 3 and the reducer 2 to be quickly disassembled and assembled as independent modules. This facilitates maintenance or replacement without disassembling the internal components of the housing 1. A drive wheel 6 is fixedly connected to the output end of the reducer 2. A driven wheel 9 is provided at the bottom of the drive wheel 6. A conveyor belt 11 is externally connected to the drive wheel 6 and the driven wheel 9. An oil scraper 8 is fixedly connected inside the housing 1. The oil scraper 8 is located on one side of the conveyor belt 11. An oil guide plate 7 is fixedly connected to the outside of the housing 1 near the oil scraper 8. This quickly guides the scraped grease to the collection container, preventing the grease from accumulating inside the housing 1 or flowing back into the cutting fluid, ensuring the continuity of the separation process and the cleanliness of the recovered oil.

[0028] A sealing frame 5 is fixedly connected inside the housing 1. The inside of the sealing frame 5 and the outside of the drive wheel 6 rotate in cooperation. A base plate 10 is fixedly installed on the outside of the bottom end of the housing 1. The conveyor belt 11 is made of PU polyurethane material. The inside of the base plate 10 and the outside of the driven wheel 9 rotate in cooperation. The oil scraper 8 is made of polyurethane board. The conveyor belt 11 is made of PU polyurethane material. Its back side has good oleophilic and hydrophobic properties. It can selectively absorb mineral oil floating on the liquid surface when immersed in cutting fluid. The oil scraper 8 is also made of polyurethane board. Its affinity matches the material of the conveyor belt 11. While achieving effective scraping, it avoids scratching or excessive wear on the working surface of the conveyor belt 11 due to excessive hardness, thus maintaining the oil absorption performance of the surface of the conveyor belt 11.

[0029] refer to Figure 3 - Figure 5 As shown, a diversion device 12 is provided inside the housing 1. The diversion device 12 includes a storage plate 121 inside the housing 1. Connecting blocks 122 are fixedly connected to both sides inside the storage plate 121. Placement blocks 123 are fixedly connected to the top of the connecting blocks 122. A baffle plate 124 is slidably connected inside the two placement blocks 123. The baffle plate 124 is located on one side of the conveyor belt 11. A conveyor plate 125 is detachably connected to the outside of the storage plate 121. Two fixing blocks 126 are fixedly connected to the bottom of the conveyor plate 125. The two fixing blocks 126 are detachably connected to the housing 1 by bolts. A guide groove 127 is opened inside the storage plate 121. A diversion plate 128 is fixedly connected inside the storage plate 121.

[0030] When the scraped grease flows, it flows inside the guide channel 127, and some of the grease comes into contact with the diverter plate 128. After the grease scraped off by the scraper plate 8 enters the guide channel 127, some of the grease comes into contact with the diverter plate 128 and is guided to the inside sides of the receiving plate 121, so that the grease is orderly diverted into the conveyor plate 125 for discharge, avoiding the accumulation of a large amount of grease in the middle of the receiving plate 121, forming turbulence or local blockage. Springs 129 are fixedly connected to both sides of the placement block 123 and both sides of the baffle plate 124. The springs 129 give the baffle plate 124 elastic floating ability. When the conveyor belt 11 is affected by load changes or pulley installation errors, When there is radial runout or slight deviation, the baffle plate 124 can adaptively adjust its position to avoid rigid hard contact with the conveyor belt 11, reducing the risk of wear or tooth surface deformation of the working surface of the conveyor belt 11 due to repeated impact. The bottom end of the baffle plate 124 near the conveyor belt 11 has a slope. When the conveyor belt 11 is running, the baffle plate 124 prevents residual oil droplets that have not been scraped off from the conveyor belt 11 from splashing into the housing 1 due to centrifugal force or vibration. At the same time, the slope at the bottom end of the baffle plate 124 near the conveyor belt 11 guides the grease adhering to the belt surface to the collection plate 121, reducing the re-adhesion of grease to the surface of the conveyor belt 11.

[0031] refer to Figure 6 - Figure 10 As shown, a cleaning device 13 is installed inside the housing 1. The cleaning device 13 includes two storage boxes 131 installed inside the housing 1. The two storage boxes 131 are located on both sides of the conveyor belt 11. Two support blocks 132 are fixedly connected to the top of the storage boxes 131. A cleaning roller 133 is rotatably connected to one end of the two support blocks 132 that is close to each other. The two cleaning rollers 133 are located on both sides of the conveyor belt 11. The two cleaning rollers 133 can clean the conveyor belt 11 and remove fine chips, dust and other solid particles that are carried along with the adsorption of floating oil from the surface of the conveyor belt 11, so as to facilitate the next oil-water separation operation. A scraper 134 is fixedly connected to the top of the storage plate 121. The scraper 134 is a wire brush. The scraper 134 is located at the bottom of the cleaning roller 133. The scraper 134 can remove dirt adhering to the surface of the cleaning roller 133 and prevent the cleaning roller 133 from losing its brushing efficiency due to saturation of surface particles.

[0032] The storage box 131 has a collection chamber 135 inside, which is used to collect the impurities after cleaning. A sealing plate 136 is fixedly connected to one side of the two storage boxes 131. A positioning block 137 is fixedly connected to the outside of the box body 1 near the sealing plate 136. The outside of the positioning block 137 is slidably connected to the inside of the sealing plate 136. A threaded post 138 is threadedly connected to the inside of the positioning block 137. A pressing plate 139 is rotatably connected to one side of the threaded post 138. The pressing plate 139 is located on one side of the sealing plate 136. The outside of the pressing plate 139 is slidably connected to the inside of the positioning block 137, so that the storage box 131 is installed inside the box body 1 in a drawer-type structure. It can be pulled out along the direction of the positioning block 137 for cleaning or replacement of the cleaning roller 133 without disassembling the box body 1. The threaded post 138 drives the pressing plate 139 to lock the sealing plate 136 laterally, ensuring the positioning stability of the storage box 131 during operation.

[0033] Working principle of the invention: During operation, after the motor 3 outside the reducer 2 starts, it drives the drive wheel 6 fixedly connected to the output end of the reducer 2 to rotate. The drive wheel 6 drives the driven wheel 9 to rotate synchronously through the conveyor belt 11. The conveyor belt 11 forms a closed loop between the drive wheel 6 and the driven wheel 9 and runs continuously in one direction. The conveyor belt 11 is made of PU polyurethane material. When immersed below the surface of the cutting fluid, it utilizes the good oleophilic and hydrophobic properties of PU material to selectively adsorb the mineral oil floating on the surface of the liquid, carry the oil film away from the liquid surface and transport it upward. When the conveyor belt 11 with the attached oil film runs to the position of the scraper 8, the cutting edge of the polyurethane scraper 8 fixed inside the housing 1 contacts the surface of the conveyor belt 11 and scrapes off the floating oil on the conveyor belt 11. At the same time, the oil guide plate 7 quickly guides the scraped grease to the external collection container to prevent the grease from accumulating or flowing back inside the housing 1.

[0034] When the conveyor belt 11 is in motion, the other side of the conveyor belt 11 moves on the surface of the baffle plate 124. The grease on the other side is guided by the baffle plate 124 to the receiving plate 121. The grease that falls into the receiving plate 121 flows along the guide groove 127 opened inside. After some grease comes into contact with the diverting plate 128, it is guided to both sides inside the receiving plate 121, so that the grease is orderly diverted into the conveyor plate 125 and discharged. The spring 129 between the baffle plate 124 and the placement block 123 adaptively adjusts its position when the conveyor belt 11 causes radial jump or offset, so as to avoid rigid hard contact with the conveyor belt 11 and reduce the risk of wear on the working surface of the conveyor belt 11. The setting of the oil scraper 8 and the baffle plate 124 can scrape off the grease on both sides of the conveyor belt 11 at the same time, thereby increasing the efficiency of oil-water separation.

[0035] After the oil-water separation operation is completed, the entire equipment is removed, and then the motor 3 is started to drive the conveyor belt 11 to move. When the conveyor belt 11 moves, the cleaning roller 133 continuously brushes the surface of the conveyor belt 11, peeling off the fine chips, dust and other solid particles that are carried along with the adsorption of floating oil from the surface of the conveyor belt 11. The peeled particles fall into the collection chamber 135 for centralized collection. The steel wire scraper 134 located at the bottom of the cleaning roller 133 promptly removes the dirt adhering to the surface of the cleaning roller 133, maintaining the brushing ability of the cleaning roller 133. The cleaning roller 133 restores the surface cleanliness of the conveyor belt 11 after the oil is scraped off, making it convenient to be immersed in the cutting fluid for the next cycle of adsorption.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
