Description

Technical Field

[0001] This utility model relates to the field of oil mist treatment technology, specifically to an oil mist classification and collection treatment device for CNC machine tools used in pump processing. Background Technology

[0002] During the machining process of CNC machine tools, the cutting fluid (or lubricating oil) comes into contact with the high-speed rotating tool and workpiece, and a large amount of oil mist is formed due to the high temperature and high pressure. This oil mist not only affects the workshop environment and harms the health of operators, but may also cause equipment failure or safety hazards. Therefore, mechanical separation, filtration separation and electrostatic separation methods are usually used to treat the oil mist. When using the filtration separation method, in order to prevent the filter screen from being adsorbed by oil and impurities and causing filter screen blockage, it is usually necessary to manually remove the filter screen from the treatment equipment for cleaning frequently. This increases the workload of the staff. Secondly, although the authorized publication number "CN221474426U" adds solvent into the chamber to achieve further purification of the filtered oil mist and reduce the environmental impact of oil mist emission, when the solvent is discharged after use, some solvent will remain at the bottom of the chamber. This can easily cause the newly added solvent to mix with the used solvent, destroying the purity of the solvent and causing a decrease in oil mist purification efficiency. Utility Model Content

[0021] Example: Figures 1-10 As shown, this utility model provides an oil mist classification and collection treatment device for CNC machine tools used in pump processing, including a treatment box 1. A mist inlet 11 is fixedly installed on the left side of the treatment box 1. A fan 12 is provided on the side of the treatment box 1 away from the mist inlet 11. The fan pipe of the fan 12 is fixedly connected to the treatment box 1. A purification box 13 is fixedly installed at the end of the fan 12 away from the treatment box 1 via the fan pipe. An air outlet pipe 14 is fixedly installed at the end of the purification box 13 away from the fan 12. The front end of the purification box 13 is fixed... The treatment box 1 is equipped with an inlet 15. Inside the treatment box 1 are a filter screen 16, a filter screen 17, and an activated carbon adsorption screen 18. The mesh size of the filter screen 16 is larger than that of the filter screen 17. An oil outlet pipe 19 is fixedly installed at the bottom of the treatment box 1. A control valve 1 is installed at the bottom of the oil outlet pipe 19. A door 10 is hinged to the front of the treatment box 1. A fixing mechanism 4 is provided between the treatment box 1 and the door 10. A reciprocating cleaning mechanism 2 is provided at the top of the treatment box 1. A drainage mechanism 3 is provided inside the purification box 13. The reciprocating cleaning mechanism 2 includes two symmetrically distributed drive shafts 21. Connecting rods 22 are fixedly installed at opposite ends of the drive shafts 21. Two symmetrically distributed moving blocks 24 are provided at the top of the treatment box 1. A through groove 25, which mates with the connecting rod 22, is opened through the middle of each moving block 24. Support rods 26 are fixedly installed on the inner sides of both moving blocks 24 via mounting blocks. The support rods 26 are slidably connected to the treatment box 1. A connecting pipe 27 is fixedly installed at the bottom end of the support rod 26. Two sets of symmetrically distributed nozzles 28 are fixedly installed at the bottom end of the connecting pipe 27. A water pump 29 is fixedly installed on the upper surface of the treatment box 1. The outlet pipe of the water pump 29 passes through the treatment box 1 and connects to the connecting pipe 27. The outlet pipe is telescopic. A water tank 20 is fixedly installed at the rear end of the treatment box 1. The water pump 29 pumps water... The pipe is connected to the water tank 20; by setting a reciprocating cleaning mechanism 2, the linkage design of the drive shaft 21, the connecting rod 22 and the moving block 24 can drive the support rod 26 and the nozzle 28 to reciprocate, so that the cleaning agent is evenly sprayed on the filter screen 16 and the filter screen 27 through the nozzle 28, thereby realizing the automatic cleaning of the filter screen 16 and the filter screen 27 without the need for frequent manual disassembly and cleaning, reducing the labor intensity of the staff, and facilitating the deep cleaning of the filter screen 16 and the filter screen 27 in the later stage. The drive shaft 21 is driven by a dual-axis motor, the connecting rod 22 is composed of a connecting plate and a round rod, a sealing gasket is provided between the treatment box 1 and the box door 10, the top of the water tank 20 is provided with a cleaning agent feeding pipe, and the top of the feeding pipe is threaded to a pipe cap, and a valve is provided on the water inlet 15.

[0022] The drainage mechanism 3 includes an inclined guide plate 31, which is V-shaped. One end of the guide plate 31 has a drain outlet 32. The bottom end of the guide plate 31 is fixedly installed with a drain pipe 33 at the bottom end of the drain outlet 32. The drain pipe 33 passes through the purification box 13, and a control valve is provided at the bottom of the drain pipe 33. By setting the drainage mechanism 3, the inclined V-shaped guide plate 31 can guide the solvent in the purification box 13 to the drain outlet 32 ​​and then discharge it from the drain pipe 33. This avoids the solvent residue after use from mixing with the newly added solvent at the bottom of the purification box 13, which would affect the purity of the solvent during each purification and improve the oil mist purification efficiency. The bottom end of the drain pipe 33 is trapezoidal.

[0023] Each of the filter screen 16, filter screen 17, and activated carbon adsorption screen 18 has a locking block 5 fixedly installed at its top. The lower inner wall of the treatment box 1 has a mounting base 51 that works with the locking block 5. By setting the locking block 5 and the mounting base 51, when installing the filter screen 16, filter screen 17, and activated carbon adsorption screen 18, the locking block 5 is inserted into the mounting base 51, thereby realizing the installation of the filter screen 16, filter screen 17, and activated carbon adsorption screen 18. The operation is simple, and it is convenient to install and disassemble, making it easy to replace and deeply clean the filter screen 16, filter screen 17, and activated carbon adsorption screen 18.

[0024] The reciprocating cleaning mechanism 2 also includes two sets of symmetrically distributed guide rods 241. The guide rods 241 are fixedly connected to the treatment box 1 and slidably connected to the moving block 24. By setting the guide rods 241, the moving block 24 will slide outside the guide rods 241 when it moves, thereby increasing the stability of the moving block 24 when it moves.

[0025] The fixing mechanism 4 includes two symmetrically distributed fixing plates 41 and two symmetrically distributed fixing blocks 42. The fixing plates 41 are fixedly connected to the door 10. A rod 43 is slidably installed in the middle of the fixing block 42. A spring 44 is fixedly installed on the lower inner surface of the fixing block 42. The spring 44 is fixedly connected to the rod 43. A lifting handle 45 is rotatably installed on the top of the rod 43. A slot for cooperating with the rod 43 is opened at the top of the fixing plate 41. By setting the fixing mechanism 4, the combination of fixing plates 41, fixing blocks 42, rod 43 and spring 44 can quickly realize the fixing or separation of the door 10 and the processing box 1, preventing the leakage of untreated oil mist, and preventing external impurities from entering the interior of the processing box 1, thus maintaining the cleanliness of the equipment operating environment.

[0026] The bottom of the treatment tank 1 is trapezoidal, and the oil outlet pipe 19 is connected to the pipeline by a frustum; this facilitates the discharge and collection of the filtered oil, and avoids the oil remaining at the bottom of the treatment tank 1, which would result in oil waste.

[0027] The nozzle 28 is inclined, which increases the contact area between the cleaning agent and the filter screen 16 and the filter screen 27, making it easier to spray the cleaning agent onto the filter screen 16 and the filter screen 27.

[0028] A support frame is fixedly installed at the bottom of the fan 12. The support frame is L-shaped. By setting up the support frame, the fan 12 is supported, and the stability of the fan 12 during operation is improved.

[0029] Working principle: In actual use, first place an oil collection box at the bottom of the treatment chamber 1, then start the fan 12. The oil mist generated by the CNC machine tool will enter the treatment chamber 1 through the mist inlet 11 under the action of the fan 12. After entering, the oil mist will pass through filter screen 16, filter screen 17 and activated carbon adsorption screen 18 for graded filtration. Filter screen 16 and filter screen 17 intercept oil mist particles of different sizes, and the larger oil droplets are intercepted on the surface of filter screen 16 and filter screen 17 and gradually condense into larger droplets. As the oil droplets accumulate, they flow downwards along filter screen 16 and filter screen 17 under the action of gravity and are discharged from the oil outlet pipe 19. The activated carbon adsorption screen 18 further adsorbs the residual tiny oil mist and odor. The filtered gas enters the purification box 13 under the action of the fan 12. Purification solvent is added into the purification box 13 through the water inlet 15 to further purify the residual oil mist in the gas. During filtration, control valve 1 is closed. When a certain amount of oil remains at the bottom of the treatment box 1, control valve 1 is opened. After each oil mist collection is completed, the oil collection box is removed and replaced with a collection cylinder or other container for collecting solvent. Then, the dual-axis motor is started to drive the drive shaft 21 to rotate, which in turn drives the connecting rod 22 to rotate. The round rod in the connecting rod 22 moves in the through groove 25, causing the moving block 24 to move vertically back and forth along the guide rod 241. At the same time, the water pump 29 is started to draw the cleaning agent in the water tank 20 into the connecting pipe 27, and then sprays it evenly on the filter screen 16 and filter screen 27 through the inclined nozzle 28, thereby achieving automatic cleaning of the filter screen 16 and filter screen 27. During the cleaning process, the oil stains are collected at the bottom of the treatment box 1 under the action of gravity, and then discharged from the oil outlet pipe 19 into the collection cylinder. When it is necessary to discharge the solvent inside the purification box 13, open the control valve 2. Under the action of the V-shaped guide plate 31, the used solvent will be collected along the guide plate 31 to the drain outlet 32, and then completely discharged through the drain pipe 33 with a trapezoidal bottom. When it is necessary to replace or deeply clean the filter screen inside the treatment box 1, turn the handle 45 in the opposite direction of the door 10. During the rotation of the handle 45, the insertion rod 43 slides in the fixing block 42, and the spring 44 contracts. When the handle 45 rotates to form a T-shape with the fixing block 42, it indicates that the insertion rod 43 has completely disengaged from the slot. Then the door 10 can be opened, and the locking blocks 5 of filter screen 16, filter screen 2 17, and activated carbon adsorption screen 18 can be removed from the mounting base 51. Then, filter screen 16 and filter screen 2 17 can be deeply cleaned.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
