Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, specifically, it relates to a solid-liquid separation device inside a chip conveyor. Background Technology

[0002] Chip conveyors are widely used in CNC machine tools to collect and transport chips from various metal or non-metal machining processes. Since some cutting processes utilize cutting fluid cooling to ensure machining efficiency, a large amount of cutting fluid also enters the chip conveyor along with the chips. Cutting fluid is a scientifically formulated compound of various high-performance additives, and its purchase and disposal costs are relatively high. It requires filtration for reuse, while chips, as a unique type of industrial processing waste, also require separate treatment.

[0003] Chinese patent CN209630722U discloses a filtration device for solid-liquid separation inside a chip conveyor. It includes an inner filter box positioned between two filter support blocks, which are fixed to the inside of the chip conveyor housing. An overflow port is located on the side of the inner filter box and connects to the chip collection box of the chip conveyor. The bottom of the inner filter box has filter mesh holes. Cutting fluid passes from the chip collection box through the inner filter box into a water tank. Waste chips deposited on the inner filter box are cleaned by a brush, and then scraped from the bottom of the chip conveyor to the head of the chip conveyor by a scraper, falling into a chip collection cart from the outlet end of the chip conveyor. A filter box cover is connected to the inner filter box to prevent cutting fluid overflow. While this device can separate the processed metal chips and cutting fluid, some cutting fluid often adheres to the metal chips and cannot be removed, ultimately preventing the recovery of this portion of the cutting fluid and resulting in waste.

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

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a solid-liquid separation device inside a chip conveyor, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A solid-liquid separation device inside a chip conveyor includes: a chip conveyor housing, characterized in that a feeding belt is provided inside the chip conveyor housing, feeding rollers are provided at both ends of the feeding belt, the feeding rollers are located outside the chip conveyor housing and connected by a connecting belt, a feeding motor is provided near the bottom of the outside of the chip conveyor housing, and a separation device is provided on the left side of the chip conveyor housing.

[0008] Optionally, an upper pressure roller is arranged near the top inside the separation device, a lower pressure roller is arranged inside the separation device in conjunction with the feeding belt, a movable frame is arranged outside the separation device in conjunction with the upper pressure roller, a slider is arranged inside the movable frame, a through hole is opened at the center of the slider, a spring column is arranged above the through hole, a spring is arranged around the outer ring of the spring column, a first motor is arranged on the front of the slider, and a second motor is arranged on the lower pressure roller outside the chip conveyor housing.

[0009] Optionally, a screen plate is provided below the lower pressure roller, a waste box one is provided below the screen plate near the left side, and a waste box two is provided below the screen plate near the right side.

[0010] Optionally, a vibration motor is installed on the outside of the separation device near the top of the sieve plate.

[0011] Optionally, a column is provided at the bottom of the chip conveyor housing, and the bottom of the column is horizontal with waste box one and waste box two.

[0012] Optionally, the upper pressure roller is located obliquely above the lower pressure roller.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] 1. The internal solid-liquid separation device of this chip conveyor uses a separation device at the end of the chip conveyor. Two pressure rollers squeeze the metal chips, filter out the residual cutting fluid on the surface of the chips, and let them fall onto the screen plate for further screening by vibration. The cutting fluid passes through the holes of the screen plate and the metal chips into different waste boxes for collection, thus achieving more efficient separation.

[0015] 2. The internal solid-liquid separation device of the chip conveyor reduces the gap by pressing the metal chips together with the pressure rollers, thereby increasing the weight of chips that the waste box can hold, which facilitates recycling. The gap between the pressure rollers can be adjusted to deal with chip clumps of different sizes and avoid chip blockage.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this embodiment provides an internal solid-liquid separation device for a chip conveyor, including: a chip conveyor housing 1.

[0028] like Figure 1-4 As shown, in this embodiment, a feeding belt 2 is provided inside the chip conveyor housing 1, and feeding rollers 3 are provided at both ends of the feeding belt 2. The feeding rollers 3 are located on the outside of the chip conveyor housing 1 and are connected by a connecting belt 4. A feeding motor 15 is provided on the outside of the chip conveyor housing 1 near the bottom, and a separation device 5 is provided on the left side of the chip conveyor housing 1. The feeding belt 2 is set close to the bottom inside the chip conveyor housing 1. The feeding rollers 3 drive the feeding belt 2 to rotate. Multiple sets of feeding belts 2 are combined to transfer the chips generated by the processing equipment from a high place downward. The feeding rollers 3 that are close to each other and connected to each other are connected by a connecting belt 4. The feeding motor 15 at the bottom drives a single feeding roller 3 to rotate. The connection between the feeding belts 2 and the connecting belt 4 finally makes all the feeding belts 2 rotate, completing the metal chip conveying work from high to low and conveying it to the separation device 5.

[0029] like Figure 1 , 2As shown, in this embodiment, an upper pressure roller 6 is arranged near the top inside the separation device 5, and a lower pressure roller 7 is arranged inside the separation device 5 in conjunction with the feeding belt 2. A movable frame 10 is arranged outside the separation device 5 in conjunction with the upper pressure roller 6. A slider 11 is arranged inside the movable frame 10. A through hole 14 is opened through the center of the slider 11. A spring column 12 is arranged above the through hole 14. A spring 13 is arranged around the outer ring of the spring column 12. A first motor 8 is arranged on the front of the slider 11, and a second motor 9 is arranged on the lower pressure roller 7 outside the chip conveyor housing 1. The upper pressure roller 6 and the lower pressure roller 7 rotate in opposite directions, squeezing the metal chips fed from the feeding belt 2, so that the gaps between the metal chips are reduced and the volume is reduced. Some of the cutting fluid attached to the surface of the metal chips is squeezed out and detached. The metal chips fall under gravity and the metal chips are separated. The solid-liquid separation process is completed by the upper pressure roller 6 driven by the first motor 8 and the lower pressure roller 7 driven by the second motor 9. Each roller has a corresponding motor connected to the shaft of the corresponding roller. The shaft of the lower pressure roller 7 is fixed to the separation device 5, while the shaft of the upper pressure roller 6 is mounted on the slider 11 inside the movable frame 10. The slider 11 can move up and down within the movable frame 10. The top spring 13 applies force to press the slider 11 to the bottom. When the metal scraps being transported are large, the upper pressure roller 6 is pushed upward, and the slider 11 compresses the spring 13. The spring post 12 is inserted into the slider 11, which increases the gap between the upper pressure roller 6 and the lower pressure roller 7. The spring 13 applies force to compress the metal scraps. This process can compress metal scraps of different sizes, preventing excessively large scraps from getting stuck at the pressure rollers and causing blockages.

[0030] like Figure 3 , 4 As shown, in this embodiment, a screen plate 16 is provided below the lower pressure roller 7. A waste box 18 is provided below the screen plate 16 near the left side, and a waste box 2 19 is provided below the screen plate 16 near the right side. The compressed metal scraps fall onto the screen plate 16 by gravity. The screen plate 16 has multiple sets of small holes. The cutting fluid separated during pressing also falls onto the screen plate 16 by gravity and falls directly into the waste box 2 19 directly below the screen plate 16 through the small holes to collect the recyclable cutting fluid. The compressed metal scraps that fall onto the screen plate 16 slide down the downward-sloping screen plate 16 and finally fall into the waste box 18 at the front end to collect the recyclable metal scraps, thus completing the solid-liquid separation and recycling work.

[0031] like Figure 3 , 4As shown, a vibration motor 17 is provided on the outside of the separation device 5 near the top of the sieve plate 16 in this embodiment. The vibration motor 17 is connected to the sieve plate 16. The front end shaft of the sieve plate 16 passes through the outside of the separation device 5 and moves inside the arc edge. The rear end shaft is fixed to the separation device 5. The vibration motor 17 strikes the sieve plate 16, causing the sieve plate 16 to vibrate. The metal debris falling on the sieve plate 16 is vibrated and moved downward until it detaches from the sieve plate 16 and falls into the waste box 18. During the vibration process, the residual cutting fluid is further thrown down through the sieve plate 16 and falls into the waste box 2 19.

[0032] like Figure 1 As shown, the bottom of the chip conveyor housing 1 in this embodiment is provided with a column 20, and the bottom of the column 20 is horizontal with the waste box 18 and the waste box 29; wherein, the column 20 raises the entire chip conveyor housing 1 and the separation device 5, so that the waste box 18 and the waste box 29 can be inserted into the bottom of the separation device 5 and removed and transferred at any time.

[0033] like Figure 4 As shown, in this embodiment, the upper pressure roller 6 is located obliquely above the lower pressure roller 7; wherein, the metal scraps conveyed from the feed belt 2 first contact the lower pressure roller 7 and are pushed to the gap between the upper pressure roller 6 and the lower pressure roller 7, and the scraps are output obliquely downward. With the help of gravity and the rotation of the two pressure rollers, the pressing is easier and the possibility of scrap clogging is reduced.

[0034] Working principle: The chips generated by the processing equipment enter the interior from the front end of the chip conveyor housing 1. They are conveyed into the separation device 5 by the feeding belt 2. The upper pressure roller 6 and the lower pressure roller 7 work together to flatten the metal chips and squeeze out the cutting fluid. The two fall onto the screen plate 16 below. The cutting fluid passes through the holes on the screen plate 16 by gravity and falls into the waste box 19 below for collection. The compressed metal chips are vibrated by the vibrating motor 17, causing the chips to slide into the waste box 18 at the front end for collection. This achieves solid-liquid separation of the slanted waste by the separation device 5.
