Technical Field
[0001] This utility model belongs to the field of oil-water separation technology, and in particular relates to an oil-water separation and filtration device for CNC machine tools. Background Technology
[0002] The oil-water separation and filtration device for CNC machine tools is a device used to separate the mixture of cutting fluid and lubricating oil. It aims to solve the problems of coolant failure, microbial growth and environmental pollution caused by oil-water mixing. It can also separate other sewage or wastewater generated during the use of CNC machine tools.
[0003] Traditional oil-water separation devices typically use sedimentation to separate oil and water. Because oil has a lower density, it floats on the water surface, making it easier to remove the surface oil later. However, because oil is quite viscous, it tends to adhere to the drain pipe during discharge, and long-term accumulation can cause blockages, making it difficult to effectively separate oil and water later. Therefore, we propose an oil-water separation and filtration device for CNC machine tools. Utility Model Content

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0036] Please see Figures 1-5 As shown, this utility model is an oil-water separation and filtration device for CNC machine tools, including a separation section 1, which is used to separate the coolant and wastewater generated by the CNC machine tool; and
[0037] Oil discharge section 2 is installed inside the separation section 1 and is used to discharge the oil pollution generated on the surface of the wastewater.
[0038] The separation unit 1 can intercept debris or garbage in the wastewater and coolant before adding wastewater, and the separation unit 1 separates oil and water by sedimentation.
[0039] The separation unit 1 includes a separation box 11, a transparent glass plate 111 is installed on the front of the separation box 11, a base 112 is fixedly connected to the bottom of the separation box 11, a partition 113 is fixedly connected to the inner wall of the separation box 11, and a drain pipe 114 is fixedly connected to the bottom of the separation box 11.
[0040] Interception box 12 is inserted into the top of separation box 11 and is used to intercept garbage in wastewater;
[0041] The deceleration assembly 13 is installed at the bottom of the interception box 12. The deceleration assembly 13 is used to decelerate the waste level so that it slowly enters the separation box 11.
[0042] Drainage assembly 14 is installed inside the separation box 11 and is used to control the opening and closing of the drain pipe 114.
[0043] The bottom of the interception box 12 has several slots, and a positioning block 121 is fixedly connected to the inside of the interception box 12. The positioning block 121 is inserted into the separation box 11 to limit the position of the interception box 12, making the interception box 12 more stable after installation. The interception box 12 can be disassembled by pulling it upward, which is convenient for subsequent cleaning of the interception box 12.
[0044] The deceleration assembly 13 includes a conical deceleration plate 131 disposed at the bottom of the interception box 12, and a vertical rod 132 is fixedly connected to the inner side of the conical deceleration plate 131. The bottom of the vertical rod 132 is fixedly connected to the bottom of the inner wall of the separation box 11.
[0045] After being discharged from the interceptor box 12, the wastewater flows onto the conical deceleration plate 131, where it mixes smoothly with the wastewater in the separation box 11, thereby reducing splashing.
[0046] The drainage assembly 14 includes a slide rod 141, a sealing plug 142 fixedly connected to the bottom of the slide rod 141, the bottom of the sealing plug 142 is tapered and adapted to the top of the drain pipe 114, the top of the slide rod 141 slides through the separation box 11 and extends to the outside, a top plate 143 fixedly connected to the top of the slide rod 141, a pull handle 144 fixedly connected to the top of the top plate 143, a rubber sleeve 145 and a spring 146 fixedly connected to the bottom of the top plate 143 respectively, and the bottom of the rubber sleeve 145 and the bottom of the spring 146 are both fixedly connected to the top of the separation box 11;
[0047] When the handle 144 is pulled upward, it will drive the sealing plug 142 upward through the slide rod 141, opening the drain pipe 114. The rubber sleeve 145 is used to cover and improve the appearance, while also protecting the spring 146.
[0048] The oil discharge section 2 includes a heating base 21 located on the right side of the partition 113. Several electric heating tubes 211 are installed inside the heating base 21. Two support blocks 212 are fixedly connected to the right side of the heating base 21. The right side of the support blocks 212 is fixedly connected to the right side of the inner wall of the separation box 11. Several oil discharge pipes 22 are fixedly connected to the right side of the partition 113. The right side of the oil discharge pipes 22 passes through the separation box 11 and extends to the outside. When the oil reaches the position on the oil discharge pipe 22, it will flow out from the oil discharge pipe 22, thereby treating the oil on the surface of the wastewater. During the process of discharging the oil, the electric heating tubes 211 on the heating base 21 are activated to heat the oil discharge pipe 22, so that the oil inside the oil discharge pipe 22 melts, thereby discharging better, reducing the occurrence of blockage, and preventing the oil from clumping when the weather is cold. The heat can also be transferred to the wastewater discharged by the partition 113, which can prevent clumping again.
[0049] Vibration assembly 23 is installed above heating base 21 and is used to make oil drain pipe 22 vibrate.
[0050] The oil drain pipe 22 passes through the partition 113 and extends to the left side of the partition 113. The oil drain pipe 22 is used to discharge the oil floating on the wastewater. Several annular protrusions 221 are fixedly connected to the outer surface of the oil drain pipe 22.
[0051] The vibration assembly 23 includes a connecting plate 231 disposed above the oil drain pipe 22. Two connecting rods 232 are fixedly connected to the bottom of the connecting plate 231. A lifting block 233 is fixedly connected to the bottom of each of the two connecting rods 232. An inner groove 234 is provided on both the front and back of the lifting block 233. A collision block 235 is slidably connected inside the inner groove 234. A second spring 236 is fixedly connected to the inner wall of the inner groove 234. The side of the second spring 236 facing the collision block 235 is fixedly connected to the inner wall of the collision block 235.
[0052] The top of the separation box 11 is fixedly connected to an electric push rod 24. The bottom output end of the electric push rod 24 is fixedly connected to the top of the connecting plate 231. The electric push rod 24 is used to drive the connecting plate 231 to move up and down reciprocally. When the electric push rod 24 is started to drive the connecting plate 231 to move up and down reciprocally, the connecting rod 232 will drive the lifting block 233 to move together. When the collision block 235 comes into contact with the annular protrusion 221, a collision will occur. This process is repeated, and the collision block 235 will continuously collide with multiple annular protrusions 221, thereby causing the annular protrusions 221 to vibrate, improving the oil discharge effect and preventing blockage.
[0053] The outer side of the annular protrusion 221 is tapered, and the top and bottom of the outer side of the collision block 235 are inclined. After the inclined surface of the collision block 235 contacts the annular protrusion 221, it can smoothly push the collision block 235 into the inner groove 234, so that the lifting block 233 can rise and fall smoothly.
[0054] One specific application of this embodiment is:
[0055] When it is necessary to separate coolant or other wastewater and sewage generated by CNC machine tools, the wastewater or coolant is poured into the interception box 12. The interception box 12 will intercept residual debris and other waste in the coolant, allowing the liquid and oil to smoothly enter the separation box 11 through the trough on the interception box 12. The liquid will first come into contact with the conical speed reducer 131, which slows down the liquid and makes it enter the separation box 11 more smoothly, reducing severe splashing. The liquid settles in the separation box 11, causing the oil to float on the surface of the wastewater. When the oil reaches the oil drain pipe 22, it will flow out from the oil drain pipe 22, thus treating the oil on the surface of the wastewater. Furthermore, staff can observe the liquid level inside the separation tank 11 through the transparent glass plate 111 to determine whether wastewater needs to be drained. When drainage is required, staff pull the handle 144, which drives the slide rod 141 upward through the top plate 143. The slide rod 141 then moves the sealing plug 142 together, opening the top of the drain pipe 114 and draining the wastewater. Simultaneously, the top plate 143 stretches the spring 146. After some wastewater has drained, the handle 144 is released, and the top plate 143 returns to its original position under the elastic action of the spring 146. At this time, the slide rod 141 and the sealing plug 142 return to their original positions, sealing the top of the drain pipe 114 and stopping the drainage.
[0056] During the oil discharge process, the electric heating element 211 on the heating base 21 is activated to heat the oil drain pipe 22. The core of the electric heating element 211 is the heating wire (resistance wire), which is usually made of iron-chromium-aluminum alloy or nickel-chromium alloy. When current passes through the heating wire, electrical energy is converted into heat energy due to resistance. This heating melts the oil inside the oil drain pipe 22, thus facilitating better discharge and reducing blockages. In cold weather, it also prevents oil from clumping, and the heat can be transferred to the wastewater discharged through the baffle 113, further preventing clumping. The electric push rod 24 is activated, which drives the connecting plate 231 to move up and down reciprocally. The connecting rod 232 will drive the lifting block 233 to move together. When the collision block 235 contacts the annular protrusion 221, a collision will occur, and the collision block 235 will be pushed into the inner groove 234. At this time, the spring 236 is squeezed, and then the collision block 235 is reset under the action of elasticity. This process is repeated, and the collision block 235 will continuously collide with multiple annular protrusions 221, thereby causing the annular protrusions 221 to vibrate, improving the oil discharge effect and preventing blockage.
