Description
Technical Field
[0001] This invention relates to the field of bolt processing technology, specifically to a wastewater recycling treatment device for bolt processing. Background Technology
[0002] In bolt manufacturing processes, common machining operations such as cutting, turning, and grinding generate large amounts of industrial wastewater. This wastewater typically contains a mixture of metal shavings, lubricating oil, coolant, and other suspended solids and dissolved pollutants. Direct discharge of this wastewater not only poses potential environmental hazards but also represents a waste of water resources and an increase in production costs. With increasingly stringent environmental regulations and the urgent need for enterprises to reduce costs and increase efficiency, the development and application of efficient and reliable wastewater recycling equipment has become crucial. Considering the characteristics of bolt processing wastewater, the core of the treatment equipment must possess the ability to effectively separate fine metal powders while appropriately treating complex organic pollutants, ultimately achieving the purification and recycling of the treated water. Bolt processing wastewater recycling equipment typically includes a sand filter tank. During operation, metal debris carried in the wastewater gradually accumulates in the gaps between the filter media particles. Furthermore, grease components from the cutting fluid adhere to the filter media surface, causing adjacent sand particles to clump together. These two problems combined significantly reduce the filtration efficiency of the sand filter tank. Moreover, there is a significant vertical gradient of contamination within the filter media layer; metal debris retention and grease caking are relatively minor in the bottom area, but these problems worsen progressively towards the upper layers. Therefore, this invention provides a bolt processing wastewater recycling equipment. Summary of the Invention
[0003] The purpose of this invention is to provide a wastewater recycling treatment device for bolt processing, so as to solve the problems mentioned in the background art.
[0004] The technical solution of this invention is: a wastewater recycling treatment device for bolt processing, comprising a sand filter tank, wherein the sand filter tank is internally divided into a filtration chamber, a material intake chamber, and a material feeding chamber. Several through-feeding holes are arranged in an array between the material intake chamber and the material feeding chamber. A material intake plate and a material feeding plate are rotatably connected to the inner cavity of the sand filter tank. Two symmetrical material intake slots are opened through the top of the material intake plate, and a material feeding slot is opened at the top of the material feeding plate. Two symmetrical electric telescopic rods are fixedly installed at the bottom of the inner cavity of the material feeding slot. A movable plate is fixedly installed between the top telescopic ends of the two electric telescopic rods. A stirring motor is fixedly installed in the inner cavity of the sand filter tank, and a rotating drum is fixedly installed at the output end of the stirring motor. Several support rods are fixedly installed at equal intervals on the left and right sides of the outer peripheral wall of the rotating drum. This device can sequentially clean the top filter material, which has the greatest impact on the filtration process, without interrupting the filtration operation, thereby improving the filtration effect of the device to a certain extent.
[0005] Preferably, a support frame is fixedly installed on the top of the sand filter tank, a drive motor is fixedly installed on the support frame, a rotating shaft is fixedly installed at the output end of the drive motor, a drive gear one and a drive gear two are fixedly sleeved on the outer peripheral wall of the rotating shaft, and a gear ring one and a gear ring two are respectively fixedly sleeved on the outer peripheral walls of the material receiving plate and the material feeding plate, and the drive gear one and the drive gear two mesh with the gear ring one and the gear ring two respectively. The drive motor drives the drive gear one and the drive gear two to rotate through the rotating shaft, and the drive gear one and the drive gear two drive the gear ring one and the gear ring two respectively. The second gear ring rotates, and the first and second gear rings drive the material-taking plate and the feeding plate to rotate respectively. The feeding trough on the feeding plate is transferred from the feeding chamber to the filtering chamber. Then, the electric telescopic rod drives the movable plate to move upward, so that the filter material on the top of the movable plate enters the bottom of the filtering chamber, thereby increasing the height of the filter material filled in the filtering chamber. The increased part of the filter material enters the material-taking trough on the material-taking plate. Then, the drive motor drives the rotating shaft to reverse, so that the material-taking plate and the feeding plate are reset to the initial state. The material wrapped in the material-taking trough falls into the material-taking chamber under the action of gravity.
[0006] Preferably, the diameter of each feeding hole is larger than the diameter of the filter material, and the gap between each pair of adjacent support rods is larger than the diameter of the filter material. Baffles are welded to the front and rear end walls of the feeding chamber. When the support rods rotate, the filter material can only move through the gap between adjacent support rods. Since the gap between adjacent support rods is slightly larger than the diameter of the filter material particles, the agglomerated filter material clumps will break into individual filter materials when passing through the gap between adjacent support rods. This improves the cleaning efficiency of the washing liquid on grease to a certain extent.
[0007] Preferably, an electromagnetic rod is fixedly installed in the central through hole of each of the support rods. Since the electromagnetic rod is fixedly installed in the middle of the support rod, when a single piece of crushed filter material passes through, the electromagnetic rod can adsorb and clean the metal debris that should not be adhered to it.
[0008] Preferably, the top of the sand filter tank is connected to a water inlet pipe, and the side wall of the sand filter tank is connected to a water outlet pipe.
[0009] Preferably, an electric push rod is fixedly installed on the top of the sand filter tank, and a sealing plate is fixedly installed on the bottom telescopic end of the electric push rod. Several air holes are opened through the top of the sealing plate, and several plug rods inserted into the air holes are welded to one side of the top of the inner cavity of the sand filter tank.
[0010] Preferably, a balancing air groove is provided through the top of the sand filter tank. An electric push rod drives the sealing plate to move downward, causing the plug rod to disengage from the air hole on the sealing plate. Then, washing liquid is added to the material receiving chamber through the water inlet pipe. The washing liquid enters the feeding chamber through the feeding hole. Finally, the liquid level of the washing liquid is maintained at a high level inside the material receiving chamber, so that the washing liquid completely submerges the filter material in the material receiving chamber. Then, the stirring motor drives the support rod to perform forward and reverse reciprocating motion through the rotating drum. Since there are two baffles welded in the filter material pool of the material receiving chamber, and the top of the baffles is provided with a lowered sealing plate, the movement range of the filter material in the material receiving chamber is restricted.
[0011] Preferably, the outer wall of the sand filter tank is connected to a biological treatment unit via a pipe.
[0012] This invention provides an improved wastewater recycling treatment device for bolt processing, which has the following improvements and advantages compared with the prior art:
[0013] 1. When the support rods rotate, the filter media can only move through the gap between two adjacent support rods. Since the gap between two adjacent support rods is slightly larger than the diameter of the filter media particles, the agglomerated filter media clumps will break into individual filter media when passing through the gap between two adjacent support rods. This improves the cleaning efficiency of the washing liquid on grease to a certain extent.
[0014] 2. Due to the small diameter of the feed orifice, the water pressure of the washing liquid passing through the feed orifice is relatively high. The vertically turbulent water flow loosens the filter media during the stirring process of the support rod, preventing jamming. The flowing water flow can also carry the filter media into the feed orifice. Since the diameter of the feed orifice is slightly larger than the diameter of the filter media particles, the incompletely broken filter media clumps are broken up a second time when passing through the feed orifice. The flowing washing liquid has more thorough contact with the filter media, which further improves the washing liquid's cleaning efficiency for grease.
[0015] 3. This device cleans the top filter media, which has the greatest impact on the filtration process, in sequence without interrupting the filtration operation. This improves the filtration effect of the device to a certain extent. Attached Figure Description

[0029] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] This invention provides an improved wastewater recycling treatment device for bolt processing. The technical solution of this invention is as follows:
[0031] like Figures 1-10As shown, a wastewater recycling treatment device for bolt processing includes a sand filter tank 1. A biological treatment unit 31 is connected to the outer wall of the sand filter tank 1 via a pipe. During use, wastewater enters the filter chamber 2 through the inlet at the top of the sand filter tank 1. The filter media inside filters the wastewater. The filtered wastewater then enters the biological treatment unit 31 through the outlet on the side wall, thus achieving a multi-stage filtration effect. The sand filter tank 1 is internally divided into a filter chamber 2, a material intake chamber 3, and a material feeding chamber 4. Several through-feed holes 5 are arranged in an array between the material intake chamber 3 and the material feeding chamber 4. A material intake plate 6 and a material feeding plate 7 are rotatably connected to the inner cavity of the sand filter tank 1. The top of the material receiving plate 6 has two symmetrical material receiving slots 8, and the top of the feeding plate 7 has a feeding slot 9. Two symmetrical electric telescopic rods 10 are fixedly installed at the bottom of the inner cavity of the feeding slot 9. A movable plate 11 is fixedly installed between the telescopic ends of the two electric telescopic rods 10. A stirring motor 12 is fixedly installed inside the sand filter tank 1. A rotating drum 13 is fixedly installed at the output end of the stirring motor 12. Several support rods 14 are fixedly installed at equal intervals on the left and right sides of the outer peripheral wall of the rotating drum 13. A support frame 15 is fixedly installed on the top of the sand filter tank 1. A drive motor 16 is fixedly installed on the support frame 15. A rotating shaft 17 is fixedly installed at the output end of the machine 16. A drive gear 18 and a drive gear 29 are fixedly sleeved on the outer peripheral wall of the rotating shaft 17. A gear ring 20 and a gear ring 21 are fixedly sleeved on the outer peripheral walls of the material receiving plate 6 and the material feeding plate 7, respectively. The drive gear 18 and the drive gear 29 mesh with the gear ring 20 and the gear ring 21, respectively. A water inlet pipe 24 is connected to the top of the sand filter tank 1, and a water outlet pipe 25 is connected to the side wall of the sand filter tank 1. After a period of use, the drive motor 16 drives the drive gear 18 and the drive gear 29 to rotate via the rotating shaft 17. The drive gear 18 and the drive gear 29 respectively drive… Gear ring 1 20 and gear ring 21 rotate, driving the material taking plate 6 and the feeding plate 7 to rotate respectively. The feeding trough 9 on the feeding plate 7 is transferred from the feeding chamber 4 to the filter chamber 2. Then, the electric telescopic rod 10 drives the movable plate 11 to move upward, so that the filter material at the top of the movable plate 11 enters the bottom of the filter chamber 2, thereby increasing the height of the filter material filled in the filter chamber 2. The increased part of the filter material enters the material taking trough 8 on the material taking plate 6. Then, the drive motor 16 drives the rotating shaft 17 to reverse, so that the material taking plate 6 and the feeding plate 7 are reset to the initial state. The material wrapped in the material taking trough 8 falls into the material taking chamber 3 under the action of gravity.
[0032] Furthermore, an electric push rod 26 is fixedly installed on the top of the sand filter tank 1, and a sealing plate 27 is fixedly installed on the bottom telescopic end of the electric push rod 26. Several air holes 28 are opened through the top of the sealing plate 27. Several plug rods 29 inserted into the air holes 28 are welded to one side of the top of the inner cavity of the sand filter tank 1. A balance air groove 30 is opened through the top of the sand filter tank 1. The electric push rod 26 drives the sealing plate 27 to move downwards, causing the plug rods 29 to disengage from the air holes 28 on the sealing plate 27; subsequently... Washing liquid is added to the material collection chamber 3 through the water inlet pipe 24. The washing liquid enters the feeding chamber 4 through the material conveying hole 5. Finally, the liquid level of the washing liquid is maintained at a high level inside the material collection chamber 3, so that the washing liquid completely submerges the filter material inside the material collection chamber 3. Then, the stirring motor 12 drives the support rod 14 to perform forward and reverse reciprocating motion through the rotating drum 13. Since there are two baffles 22 welded in the filter material pool of the material collection chamber 3, and the top of the baffles 22 is provided with a downwardly moved sealing plate 27, the movement range of the filter material in the material collection chamber 3 is restricted.
[0033] Furthermore, the diameter of each of the feeding holes 5 is larger than the diameter of the filter material, and the gap between each pair of adjacent support rods 14 is larger than the diameter of the filter material. Baffles 22 are welded to the front and rear end walls of the feeding chamber 3. When the support rods 14 rotate, the filter material can only move through the gap between adjacent support rods 14. Since the gap between adjacent support rods 14 is slightly larger than the diameter of the filter material particles, the agglomerated filter material clumps will break into individual filter materials when passing through the gap between adjacent support rods 14. This measure enhances the cleaning efficiency of the washing liquid on grease to a certain extent.
[0034] Furthermore, an electromagnetic rod 23 is fixedly installed in the central through hole of each of the support rods 14. Since the electromagnetic rod 23 is fixedly installed in the middle of the support rod 14, when a single filter material after crushing passes through, the electromagnetic rod 23 can adsorb and clean the metal debris that should not be adhered to it.
[0035] Working principle: In the initial state, the filter chamber 2 is filled with filter media, and the top of the movable plate 11 in the feeding chamber 4 carries the filter media, but the height of the material carried does not exceed the top of the feeding plate 7; when in use, wastewater enters the filter chamber 2 through the inlet at the top of the sand filter tank 1, and the filter media inside can filter the wastewater. The filtered wastewater enters the biological treatment unit 31 through the outlet on the side wall, thereby achieving the effect of multi-stage filtration.
[0036] After a period of use, the drive motor 16 drives the drive gear 18 and drive gear 19 to rotate via the rotating shaft 17. The drive gear 18 and drive gear 19 drive the gear ring 20 and gear ring 21 to rotate, respectively. The gear ring 20 and gear ring 21 drive the material-taking plate 6 and the feeding plate 7 to rotate, respectively. The feeding groove 9 on the feeding plate 7 is transferred from the feeding chamber 4 to the filter chamber 2. Then, the electric telescopic rod 10 drives the movable plate 11 to move upward, so that the filter material at the top of the movable plate 11 enters the bottom of the filter chamber 2, thereby increasing the height of the filter material filled in the filter chamber 2. The increased part of the filter material enters the material-taking groove 8 on the material-taking plate 6. Then, the drive motor 16 drives the rotating shaft 17. Reversal causes the material receiving plate 6 and the feeding plate 7 to return to their initial state. The material enclosed in the material receiving trough 8 falls into the material receiving chamber 3 under the action of gravity. Subsequently, the electric push rod 26 drives the sealing plate 27 to move downward, causing the plug rod 29 to disengage from the air hole 28 on the sealing plate 27. Then, washing liquid is added into the material receiving chamber 3 through the water inlet pipe 24. The washing liquid enters the feeding chamber 4 through the conveying hole 5. Finally, the liquid level of the washing liquid is maintained at a high level inside the material receiving chamber 3, so that the washing liquid completely submerges the filter material in the material receiving chamber 3. Then, the stirring motor 12 drives the support rod 14 to perform forward and reverse reciprocating motion through the rotating drum 13. Since there are two baffles 22 welded in the filter material pool of the material receiving chamber 3, and the top of the baffles 22 is provided with a downward movement mechanism. The sealing plate 27 at the rear restricts the movement range of the filter media in the feeding chamber 3. When the support rod 14 rotates, the filter media can only move through the gap between two adjacent support rods 14. Since the gap between two adjacent support rods 14 is slightly larger than the diameter of the filter media particles, the agglomerated filter media clumps will break into individual filter media when passing through the gap between two adjacent support rods 14. This enhances the cleaning efficiency of the washing liquid on grease to a certain extent. In addition, since an electromagnetic rod 23 is fixedly installed in the middle of the support rod 14, when the broken individual filter media pass through, the electromagnetic rod 23 can adsorb and clean the metal debris that should not adhere to it. In addition, during the rotation of the support rod 14, the electric telescopic rod is installed. 10 drives the movable plate 11 to reciprocate up and down. When the movable plate 11 moves upward, it pushes the washing liquid on its top through the feed hole 5 into the feeding chamber 3. Because the diameter of the feed hole 5 is small, the water pressure of the washing liquid through the feed hole 5 is large. The vertical turbulent water flow loosens the filter material during the stirring process of the support rod 14, preventing jamming. At the same time, the flowing water flow can also carry the filter material into the feed hole 5. Because the diameter of the feed hole 5 is slightly larger than the diameter of the filter material particles, the filter material clumps that are not completely broken will be broken a second time when passing through the feed hole 5. In addition, the flowing washing liquid has more sufficient contact with the filter material, which further enhances the washing efficiency of the washing liquid in cleaning grease.
[0037] Subsequently, the electric telescopic rod 10 stops operating, and the broken-up filter media particles fall through the conveying hole 5 onto the top of the movable plate 11 in the feeding chamber 4; then the electric telescopic rod 10 drives the movable plate 11 to move downward, and then the water outlet pipe 25 is opened, allowing the washing liquid in the sand filter tank 1 to be discharged through the water outlet pipe 25; then the sealing plate 27 moves upward, and the plug rod 29 blocks the air hole 28, forming a sealed cavity between the material taking chamber 3 and the feeding chamber 4; then the electric telescopic rod 10 drives the movable plate 11 to move downward, increasing the space in the feeding chamber 4, and the gas in the material taking chamber 3 flows into the feeding chamber 4 through the conveying hole 5, which, in conjunction with the rotating support rod 14, removes the gas trapped in the material taking chamber 3. The filter media particles in the material chamber 3 are conveyed to the feeding chamber 4 through the conveying hole 5; then the drive motor 16 drives the picking plate 6 and the feeding plate 7 to rotate again, thereby transferring the cleaned filter media to the bottom of the filter chamber 2; then the magnetism of the electromagnetic rod 23 is briefly removed, causing the adsorbed metal debris to fall off, and the metal debris is discharged from the inner cavity of the sand filter tank 1 by the flushing of water; then the picking plate 6 and the feeding plate 7 perform the picking, cleaning and feeding operations on the filter media in the filter chamber 2 again; this device cleans the top filter media in the filter chamber 2, which has the greatest impact, without interrupting the filtration operation, which improves the filtration effect of the device to a certain extent.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
