Description

Technical Field

[0001] This utility model belongs to the field of coolant recovery technology, specifically, it relates to a machining coolant recovery and filtration device. Background Technology

[0002] In machining, coolant serves as a key auxiliary material for improving machining efficiency and quality, and its application covers various machining processes such as turning, milling, and grinding. During operation, these coolants significantly enhance the overall efficiency of machining by reducing cutting temperature, minimizing tool wear, and improving workpiece surface finish. After a single use, coolant can be recycled and reused to reduce operating costs. The recycling process requires filtration to remove impurities such as metal shavings and abrasive particles.

[0003] When filtering coolant, most existing equipment uses a filter screen. However, the filter screen is in a static state, and impurities such as metal shavings and abrasive particles in the coolant accumulate on the filter screen to form a "filter cake layer". During static filtration, the pores of the filter cake will be gradually blocked by fine particles, resulting in an exponential decrease in filtration throughput.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the technical problem of metal shavings, abrasive particles, and other impurities accumulating on the filter screen in the coolant to form a "filter cake layer," which gradually clogs the pores of the filter cake during static filtration, leading to a decrease in filtration throughput, the basic concept of this utility model is as follows:

[0006] A machining coolant recovery and filtration device includes a filter box and support legs disposed at the bottom of the filter box. The filter box is equipped with a filtration mechanism and a cleaning mechanism. The filtration mechanism includes a vibration component and a filter plate disposed inside the filter box. The filter plate has first sliders disposed on both outer walls. The filter plate is used to filter coolant. The first sliders can drive the filter plate to move up and down through the vibration component. The cleaning mechanism includes a push frame disposed on the top surface of the filter plate. The push frame can move laterally along the filter plate.

[0007] According to the aforementioned machining coolant recovery and filtration device, the vibration assembly includes a support plate disposed on the outer wall of the filter box, a motor disposed on the support plate, a rotating shaft disposed at the output end of the motor, a rotating push rod disposed on the outer wall of the rotating shaft, a groove being formed in the inner wall of the filter box, a first sliding rod disposed on the inner wall of the groove, a first slider being slidably disposed on the outer wall of the first sliding rod, a first spring being disposed at the bottom end of the first slider, and the end of the first spring away from the first slider being disposed at the bottom end of the inner wall of the groove.

[0008] According to the aforementioned machining coolant recovery and filtration device, the cleaning mechanism further includes a slid groove formed on the top surface of the filter plate. A second slide rod is provided on the inner wall of the slid groove, and a second slider is slidably provided on the outer wall of the second slide rod. A second spring is provided on one side of the outer wall of the second slider, and the end of the second spring away from the second slider is provided on the inner wall of the slid groove. The bottom end of the push frame is provided on the top surface of the second slider.

[0009] According to the aforementioned machining coolant recovery and filtration device, there are two rotating push rods, which are distributed symmetrically on the outer walls of the left and right sides of the rotating shaft.

[0010] According to the aforementioned machining coolant recovery and filtration device, the number of the first sliders is two, and the first sliders are distributed in a left-right symmetrical structure on the left and right outer walls of the filter plate.

[0011] According to the aforementioned machining coolant recovery and filtration device, a force-bearing block is provided on the top surface of the push frame, an extrusion block is provided on the inner wall of the filter box, and a storage groove is provided on the top surface of the filter plate.

[0012] According to the aforementioned machining coolant recovery and filtration device, the force-bearing block and the extrusion block are respectively provided with inclined surfaces, and the inclined surfaces of the force-bearing block and the extrusion block are appropriately matched.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention uses a vibration assembly and a first slider to drive the filter plate to perform dynamic vibration filtration. This mechanical force breaks down the filter cake's accumulation structure, transforming the dense filter cake layer into a loose state, thereby preventing the filter plate from clogging during the filtration process and improving the filtration effect.

[0015] This invention utilizes the downward movement of the force-bearing block, which is then squeezed by the extrusion block, thereby causing the push frame to move to the left. This pushes and frictionally cleans the filter plate, pushing the loosened filter cake impurities to the storage tank for collection and storage. This further improves the cleaning effect and facilitates subsequent centralized cleaning by staff.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0024] like Figures 1 to 4 As shown, a machining coolant recovery and filtration device includes a filter box 1 and a support leg 2 disposed at the bottom of the filter box 1. The filter box 1 is provided with a filtration mechanism 31 and a cleaning mechanism 32. The filtration mechanism 31 includes a vibration component and a filter plate 318 disposed inside the filter box 1. The outer walls on both sides of the filter plate 318 are provided with first sliders 316. The filter plate 318 is used to filter the coolant. The first sliders 316 can drive the filter plate 318 to move up and down through the vibration component to prevent static filtration. The cleaning mechanism 32 includes a push frame 324 disposed on the top surface of the filter plate 318. The push frame 324 can move laterally along the filter plate 318 to clean the filter cake impurities that are pushed and loosened by vibration.

[0025] Furthermore, the vibration assembly includes a support plate 311 disposed on the outer wall of the filter box 1, a motor 312 disposed on the support plate 311, a rotating shaft 313 disposed at the output end of the motor 312, a rotating push rod 314 disposed on the outer wall of the rotating shaft 313, a groove is provided on the inner wall of the filter box 1, a first sliding rod 315 is disposed on the inner wall of the groove, a first slider 316 is slidably disposed on the outer wall of the first sliding rod 315, a first spring 317 is disposed at the bottom end of the first slider 316, and the end of the first spring 317 away from the first slider 316 is disposed at the bottom end of the inner wall of the groove.

[0026] Furthermore, there are two rotating push rods 314, which are distributed symmetrically on the left and right outer walls of the rotating shaft 313. This allows force to be applied simultaneously to the top surfaces of the left and right sides of the filter plate 318, thus ensuring that the filter plate 318 does not tilt during movement.

[0027] Furthermore, there are two first sliders 316, which are distributed symmetrically on the left and right outer walls of the filter plate 318. This allows the filter plate 318 to be supported and moved from the left and right sides, thereby improving the stability of the filter plate 318 during movement.

[0028] The cleaning mechanism 32 also includes a groove formed on the top surface of the filter plate 318. A second slide rod 321 is provided on the inner wall of the groove. A second slider 322 is slidably provided on the outer wall of the second slide rod 321. A second spring 323 is provided on one side of the outer wall of the second slider 322. The end of the second spring 323 away from the second slider 322 is provided on the inner wall of the groove. The bottom end of the push frame 324 is provided on the top surface of the second slider 322.

[0029] Furthermore, a force-bearing block 325 is provided on the top surface of the push frame 324, an extrusion block 326 is provided on the inner wall of the filter box 1, and a storage groove 327 is provided on the top surface of the filter plate 18.

[0030] Furthermore, the force-bearing block 325 and the compression block 326 are respectively provided with inclined surfaces. The inclined surfaces of the force-bearing block 325 and the compression block 326 are fitted together, which allows them to better receive and apply force.

[0031] The implementation principle of the machining coolant recovery and filtration device in this embodiment is as follows: During filtration, coolant is first introduced into the filter box 1 through the through hole at the top. The coolant will then pass through the filter plate 318 for filtration. Simultaneously, the motor 312 is started during the filtration process, and its output end will drive the rotating shaft 313 to rotate. The rotation of the rotating shaft 313 will drive the rotating push rod 314 to rotate. The rotation of the rotating push rod 314 will contact and squeeze the filter plate 318. The squeezed filter plate 318 will generate a downward force, thereby driving the first slider 316 to move downward on the outer wall of the first slide rod 315. Simultaneously, during the movement of the first slider 316, it will compress the first spring 317. As the rotating push rod 314 continues to rotate and no longer contacts the filter plate 318, the first spring 317 will rebound upward, thereby pushing the first slider 316 to move upward. The reset sliding of the first slider 316 can drive the filter plate 318 to reset upward. By repeating this process, the filter plate 318 can be driven to vibrate up and down. This prevents the filter plate 318 from being in a static filtration state, thereby breaking the accumulation structure of the filter cake through mechanical force, turning the dense filter cake layer into a loose state, thus preventing the filter plate 318 from clogging during the filtration process, thereby improving the filtration effect.

[0032] When the filter plate 318 moves downward, it will cause the force block 325 to move downward. At this time, the force block 325 can contact and be squeezed by the squeezing block 326. The squeezed force block 325 can generate a force to move to the left, thereby driving the push frame 324 to move through the sliding connection between the second slider 322 and the second slide rod 321. At the same time, during the movement of the second slider 322, the second spring 323 can be stretched. Through the movement of the push frame 324, the filter plate 318 can be pushed and rubbed to clean it, thereby cleaning the filter cake loosened by vibration. Then, the cleaned filter cake impurities are pushed to the storage tank 327 for centralized collection, thereby further improving the filtration effect and facilitating the subsequent centralized collection of impurities by the staff. Afterward, when the filter plate 318 moves upward and the force block 325 is no longer squeezed by the squeezing block, the second spring can rebound and drive the push frame to reset.
