Abstract
Description
Technical Field
[0001] This utility model relates to an automated descumming device for a centralized cutting fluid water supply system, and belongs to the field of machining equipment technology. Background Technology
[0002] In the machining industry, such as turning, milling, and grinding, cutting fluid (or coolant) plays a crucial role. It not only effectively reduces the temperature of the cutting zone, decreases tool wear, and improves machining accuracy and surface finish, but also flushes away chips and prevents workpiece corrosion. To improve utilization efficiency and management, modern workshops widely adopt centralized fluid supply systems. These systems include large circulating filtration tanks (collection tanks, return tanks, etc.) for recycling, storing, filtering, and re-pumping to various processing equipment.
[0003] During the circulation process, cutting fluid mixes with machine tool lubricating oil, metal shavings, fine dust, and impurities (such as graphite and ceramic particles) detached from workpieces and cutting tools. These accumulate on the surface of the fluid, forming a viscous scum layer (or scum) composed of foam, oil, and fine suspended matter. This scum layer not only hinders normal heat exchange between the cutting fluid and air, leading to reduced heat dissipation efficiency and exacerbating fluid deterioration and foul odor, but it also traps impurities, making it difficult for them to settle and enter the filtration system. The continuously accumulating scum layer can even corrode the circulating filter tank and piping system, and affect the accuracy of fluid level detection.
[0004] Currently, most centralized liquid supply systems rely primarily on sedimentation and filtration systems located on the sides or bottom of the tank (such as paper tape filters, magnetic separators, and vortex separators) to remove impurities from their circulating filtration tanks. However, the main function of these filtration systems is to remove solid particles that have settled or are suspended deep within the liquid. Their effectiveness in removing light foam, grease, and fine impurities adhering to the liquid surface is very limited. This foam layer can float on the surface of the circulating filtration tank for extended periods, becoming a cleaning dead zone that is difficult to remove by the filtration system alone. This severely affects the performance stability and lifespan of the cutting fluid, increasing maintenance costs and environmental impact. Therefore, there is an urgent need to develop a specialized device that can efficiently and automatically remove the foam impurity layer from the surface of the circulating filtration tank to compensate for the shortcomings of existing filtration technologies and improve the overall operational efficiency and environmental hygiene of centralized liquid supply systems.

[0024] See Figure 1-5 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a mounting base plate 1, a lifting mechanism at the front end of the mounting base plate 1, and a moving mechanism at the rear end of the mounting base plate 1. The moving mechanism includes a guide rail 6 and a moving motor 12. The guide rail 6 is mounted on the circulating filter tank, and the mounting base plate 1 is located above the guide rail 6. A rack 14 is provided on the top of the guide rail 6. The moving motor 12 is fixed on the mounting base plate 1, and a drive gear 13 is provided at the output shaft end of the moving motor 12 to mesh with the rack 14. A collection pusher 4 is provided at the front end of the lifting mechanism. In this embodiment, a dual-axis moving device is used to remove foam by mounting it on the circulating filter tank. Specifically, the guide rail is set on the circulating filter tank, and the mounting base plate is set on the guide rail. The moving motor drives the drive gear at the front end to mesh with the rack 14. The rack and pinion mechanism enables the equipment to reciprocate on the circulating filter tank. Descum removal is primarily achieved through a collection bucket. During this reciprocating motion, descum enters the collection bucket and, after reaching the front of the tank, is lifted by a lifting mechanism to pour the descum into an external collection device. In practice, the collection bucket is first moved to the end of the circulating filter tank, and then lowered by the lifting mechanism, with half of the bucket submerged in the coolant. This ensures maximum descum movement towards the front, achieving descum removal. Automated operation effectively collects and removes descum from the coolant in the circulating filter tank, significantly improving subsequent coolant filtration efficiency and thus enhancing the coolant's performance during processing, ensuring processing quality.
[0025] More specifically, the lifting mechanism includes a lifting bracket 2, a guide platform 3, and a lifting platform 10. The lifting bracket 2 is located at the front end of the mounting base plate 1, the guide platform 3 is located at the top of the lifting bracket 2, and the lifting platform 10 is provided with two guide columns 5, the tops of which pass through the guide platform 3. The lifting mechanism also includes a lifting motor 7, a fixed pulley group 8, and a movable pulley group 9. The fixed pulley group 8 is located at the bottom center of the guide platform 3, the movable pulley group 9 is located at the middle of the surface of the lifting platform 10, and the lifting motor 7 is located at the rear center of the mounting base plate 1. The output end of the lifting motor 7 is provided with a traction rope 11 connected to the fixed pulley group 8 and the movable pulley group 9. The guide platform 3 is provided with two guide grooves 301 that are clearance-fitted with the guide columns 5. In this embodiment, the lifting mechanism mainly controls the lifting platform through the cooperation of the drive motor, the fixed pulley group, and the movable pulley group. During the lifting process, the guide columns are constrained by the guide platform, thus achieving smooth lifting.
[0026] More specifically, the upper and lower parts of the rear end of the collecting push bucket 4 are provided with two sets of connecting seats 401. The bottom connecting seat 401 is hinged to the mating seat provided at the bottom front end of the lifting platform 10. The middle part of the surface of the lifting platform 10 is provided with an electric push rod 15. The electric push rod 15 is located below the movable pulley group 9, and the front end of the electric push rod 15 is hinged to the connecting seat 401 on the upper part of the collecting push bucket 4. In order to remove the foam, the collecting push bucket is a movable structure in this embodiment. With the setting of the two connecting seats, when it moves to the front collection point of the circulating filter pool, the collecting push bucket moves upward, the electric push rod is activated to push the upper part of the collecting push bucket out, and the collecting push bucket rotates around the lower connecting seat, thereby realizing the pouring of the foam collected inside into the external collection device.
[0027] More specifically, the fixed pulley group 8 includes three sets of parallel fixed pulleys, all fixed on the same fixed shaft. The middle fixed pulley is connected to the lifting motor 7 via a traction rope 11, and the two side fixed pulleys are connected to the movable pulley group 9. The movable pulley group 9 includes two sets of parallel pulleys, both fixed on the same fixed shaft, and connected to the two side fixed pulleys in the fixed pulley group 8 via traction ropes 11. There are three sets of traction ropes 11: one set connects the lifting motor 7 to the middle fixed pulley in the fixed pulley group 8, and the other two sets are used to connect the two side fixed pulleys in the fixed pulley group 8 to the fixed pulleys in the fixed pulley group 8. In this embodiment, to ensure smooth lifting of the lifting platform, a double-pulley lifting structure is set up in the two sets of pulleys in the movable pulley group 9. The upper fixed pulley group has three sets of fixed pulleys. The middle fixed pulley works with the lifting motor, while the two sets of fixed pulleys on both sides work with the two sets of pulleys in the lower movable pulley group. At the same time, the traction rope is also divided into three sections. One section is used for the lifting motor to drive the fixed pulley group to rotate, thereby driving the other two sections of traction rope to be wound onto the fixed pulleys on both sides, which in turn drives the lower movable pulley group to rise. When driven in the opposite direction, it descends. The double-pulley design makes the lifting process more stable.
[0028] More specifically, the mounting base plate 1 is bent upwards in a Z-shape on both sides to form a movable mating plate 101. The movable mating plate 101 has four gear slots 102, one of which meshes with the drive gear 13. A guide rail mating plate 104 is vertically arranged on the inner top of the movable mating plate 101. The bottom of the guide rail mating plate 104 is bent inwards to form an outer guide block 105. An inner guide plate 103 is arranged opposite to the outer guide block 105 on the inner vertical section of the movable mating plate 101. Both the outer guide block 105 and the inner guide plate 103 have rounded chamfered ends. The movable mating plate 101... Three mating gears 16 are also provided at the top. The three mating gears 16 are mounted on the movable mating plate 101 by a bracket, and the mating gears pass through the gear groove 102 and mesh with the rack 14. The lower middle part of both sides of the guide rail 6 is provided with guide rail grooves 601, which cooperate with the outer guide block 105 and the inner guide plate 103. In this embodiment, in order to fix the mounting base plate, guide rail mating plates are provided on both sides, and the guide rail mating plates are also guide structures. Through the cooperation with the guide rail groove, not only is the connection and fixation between the mounting base plate and the guide rail realized, but also the mounting base plate can drive the various components on it to move on the guide rail.
[0029] The working principle of this utility model is as follows: During equipment installation, first, two guide rails 6 are fixed to the side frame along the length of the circulating filter tank. Then, the mounting base plate 1 is installed on the guide rails 6 through the cooperation of the outer guide block 105 and the inner guide plate 103 with the guide rails 6. Finally, the lifting mechanism and the moving mechanism are installed. After the equipment is started, the moving motor 12 drives the drive gear 13 to rotate, which moves the mounting base plate 1 through meshing with the rack 14. The meshing of the three mating gears 16 with the rack 14 not only enables the movement but also supports the mounting base plate 1. During operation, the mounting base plate 1 is at the end of the circulating filter tank, and the lifting mechanism... The lifting platform 10 is raised and lowered by the lifting motor 7 driving the traction rope 11, so that half of the main body of the collecting bucket 4 is immersed in the coolant. It starts to move from the end of the circulating filter pool and begins to collect the foam on the surface of the circulating filter pool. When it moves to the front of the circulating filter pool, where a foam collection device is set, the lifting mechanism raises the collecting bucket 4. After it is higher than the circulating filter pool, the electric push rod 15 is activated, and the collecting bucket 4 tilts forward, thereby pouring the collected foam into the collection device. This circulation method can effectively collect and remove foam impurities on the surface of the coolant in the circulating filter pool.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
