Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and particularly relates to a wastewater recycling treatment device for chemical production. Background Technology

[0002] In the field of chemical production wastewater recycling treatment, cartridge filter equipment is widely used due to its simple structure and convenient operation. Its core requirement is to achieve efficient filtration, cleaning and recycling of solid impurities in wastewater to ensure production continuity and environmental compliance. However, existing chemical wastewater filtration equipment has many specific drawbacks and is difficult to adapt to the demand for efficient treatment.

[0003] When using a cartridge filter, impurities tend to accumulate and clog in certain areas. Existing equipment often uses a spray mechanism to spray impurities from the outside onto the cartridge, causing the impurities attached to the inner wall of the cartridge to detach and thus separate the impurities from the wastewater. However, when faced with some sticky residues or residues stuck in the gaps of the cartridge, the spray method cannot effectively clean the impurities on the surface of the cartridge. After long-term use, this will cause the cartridge to clog, thereby affecting the filtration efficiency of the equipment.

[0004] Wastewater discharged after chemical production contains various solid residues. When these solid residues enter the equipment, they settle at the bottom. During the rotation of the filter cartridge, the solid residues cannot rotate along with the filter cartridge's inner wall, causing them to remain and roll inside the equipment. This can easily cause friction and damage to the inner wall of the filter cartridge, and also increases the risk of blockage in localized areas of the filter cartridge. Summary of the Invention

[0005] The purpose of this invention is to provide a wastewater recycling treatment device for chemical production, aiming to solve the technical problems existing in the prior art mentioned in the background.

[0006] The present invention is implemented as follows: a wastewater recycling treatment device for chemical production includes a housing, a support, and rollers. The support is mounted on the surface of the housing, and the rollers are mounted on the support. The device also includes: The frame is installed inside the housing and slides with the rollers. The filter cartridge is mounted on the frame; A differential rotation assembly, located inside the housing, is used to periodically rotate the frame and filter cartridge in a staggered manner. The differential rotation assembly includes a reciprocating lead screw rotatably connected inside the housing. A first gear is fixedly connected to the end of the reciprocating lead screw. A first toothed ring fixedly connected to the surface of the filter cartridge meshes with the first gear. A second gear is fixedly connected to the surface of the reciprocating lead screw. A second toothed ring fixedly connected to the surface of the frame meshes with the second gear. The scraping assembly, located inside the housing, is used to scrape the filter residue on the inner wall of the filter cartridge; The crushing component, located inside the housing, is used to crush particulate matter in wastewater; The spray module, installed inside the housing, is used to rinse the filter residue adhering to the filter cartridge.

[0007] As a preferred technical solution of the present invention: the scraping assembly includes a magnetic slide block that slides in cooperation with a reciprocating lead screw. Universal wheels are symmetrically rotatably connected to the surface of the magnetic slide block, and both universal wheels roll in contact with the surface of the filter cartridge. A sludge collection tray is fixedly connected to the bracket, and a drain port is provided at the end of the sludge collection tray. A toothed rod is fixedly connected to the top of the sludge collection tray, and a slide frame is slidably connected to the toothed rod. A first transmission shaft rotatably connected to the side wall of the slide frame meshes with the toothed rod. A toothed shaft is rotatably connected inside the slide frame, meshing with the surface of the first transmission shaft. A roller brush is fixedly connected to the end side of the toothed shaft.

[0008] As another preferred technical solution of the present invention: magnetic plates with opposite magnetic poles are installed on the adjacent sides of the magnetic slide and the slide frame, the scraper on the surface of the roller brush is bent, and the scraper on the surface of the roller brush abuts against the inner wall of the filter cartridge.

[0009] As another preferred technical solution of the present invention: the spray modules are symmetrically distributed inside the outer shell, and multiple spray nozzles are installed on the surface of the spray modules, all of which face the sludge collection tray.

[0010] As another preferred technical solution of the present invention: the crushing component includes a round rod located inside the outer shell and rotatably connected to a support. A transmission gear is fixedly connected to the surface of the round rod. A main gear plate fixedly connected to the inner wall of the frame meshes with the transmission gear. A limiting ring fixedly connected to the inner wall of the frame slides with the outer wall of the round rod. A protrusion fixedly connected to the inner wall of the frame abuts against the end side of the round rod. A turntable is rotatably connected to the support. A first spring is fixedly connected between the end of the round rod and the turntable. A transmission gear plate is rotatably connected to the support. A first gear plate fixedly connected to the surface of the round rod meshes with the transmission gear plate. A second gear plate is rotatably connected to the round rod and meshes with the transmission gear plate.

[0011] As another preferred technical solution of the present invention: a first grinding disc is fixedly connected to the side of the second gear disc near the second grinding disc, a sleeve is rotatably connected to the surface of the first grinding disc, an eccentric pump is installed at the bottom of the sleeve, a second drive shaft is rotatably connected to the middle of the eccentric pump, the end of the second drive shaft away from the eccentric pump is rotatably connected to the outer wall of the bracket, a drive belt is connected between the round rod and the second drive shaft, a suction cup is fixedly connected to the bottom of the eccentric pump, and a spiral guide plate is fixedly connected to the inner wall of the frame.

[0012] As another preferred technical solution of the present invention: when the end of the round rod abuts against the protrusion, the adjacent sides of the first grinding disc and the second grinding disc are in contact, the edges of the first grinding disc and the second grinding disc are chamfered, and the outer wall of the sleeve is uniformly provided with water permeable holes.

[0013] The beneficial effects of the embodiments of the present invention are as follows: 1. When the filter cartridge rotates, it drives the reciprocating screw and the first gear to rotate together through the first gear ring, so that the second gear is always in a rotating state. When the second gear ring of the frame meshes with the second gear, the difference in gear ratio will cause the frame and the filter cartridge to rotate at different speeds. The frame will rotate relatively inside the filter cartridge, so that the frame scrapes the inner wall of the filter cartridge, and the frame and the filter cartridge will produce a self-cleaning effect through friction.

[0014] 2. When the slide is sliding, the first drive shaft on its side wall will mesh with the upper surface of the slide and rotate. During the rotation, the first drive shaft will drive the roller brush to rotate together by meshing with the gear shaft. During the rotation, the roller brush will scrape the inner wall of the filter cartridge and clean the gaps of the frame, so as to prevent residue from adhering to the gaps of the frame and being unable to fall off, which would reduce the filtration effect of the equipment.

[0015] 3. The round rod will slide towards the side closer to the support, the first spring will be compressed and elastically contracted, the distance between the first grinding disc and the second grinding disc will be shortened, so that the solid residue between the first grinding disc and the second grinding disc will be ground and crushed. The crushed residue will fall back into the filter cartridge through the water inlet of the sleeve, so that the solid residue will not always remain inside the frame, reducing the wear caused by the solid residue rolling inside the filter cartridge when the filter cartridge rotates, and preventing the residue from clogging inside the filter cartridge and affecting the filter cartridge filtration efficiency.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0020] like Figures 1 to 6 As shown, in one embodiment, a wastewater recycling treatment device for chemical production is proposed, including a housing 1, a support 2, and rollers 3. The support 2 is mounted on the surface of the housing 1, and the rollers 3 are mounted on the support 2. The device also includes: The frame 4 is installed inside the outer casing 1 and slides with the roller 3; Filter cartridge 5 is installed on frame 4; The differential rotation assembly 6 is disposed inside the housing 1 and is used to periodically rotate the frame 4 and the filter cartridge 5 in a staggered manner. The differential rotation assembly 6 includes a reciprocating lead screw 61 rotatably connected inside the housing 1. A first gear 62 is fixedly connected to the end side of the reciprocating lead screw 61. A first toothed ring 63 fixedly connected to the surface of the filter cartridge 5 meshes with the first gear 62. A second gear 64 is fixedly connected to the surface of the reciprocating lead screw 61. A second toothed ring 65 fixedly connected to the surface of the frame 4 meshes with the second gear 64. The scraping assembly 7 is located inside the housing 1 and is used to scrape the filter residue on the inner wall of the filter cartridge 5. The crushing component 8 is located inside the housing 1 and is used to crush particulate matter in wastewater; The spray module 9 is installed inside the housing 1 and is used to rinse the filter residue attached to the filter cartridge 5.

[0021] In practical application, the operator installs the outer casing 1 into the water channel and makes the edge of the outer casing 1 fit tightly against the inner wall of the water channel. The sewage in the water channel is blocked by the outer casing 1 and can only flow through the inside of the outer casing 1.

[0022] After the outer casing 1 is installed, the staff starts the outer casing 1, and the rollers 3 on the bracket 2 begin to rotate. The rotation of the rollers 3 causes the frame 4 and the filter cartridge 5 inside the outer casing 1 to rotate together. The sewage in the water channel is filtered by the filter cartridge 5 and flows to the bottom of the outer casing 1, and then flows back into the water channel from the bottom of the outer casing 1. After the sewage is filtered by the filter cartridge 5, the residue in the sewage will adhere to the inner wall of the filter cartridge 5. Through the rotation of the filter cartridge 5 inside the outer casing 1, the residue filtered out of the sewage will not accumulate in a local area of ​​the filter cartridge 5, thereby ensuring that the outer casing 1 can continuously filter the sewage. When the filter cartridge 5 rotates, it will cause the residue in the sewage to turn over inside the outer casing 1.

[0023] The spray module 9 draws water from the filtered side of the water channel and sprays it onto the surface of the filter cylinder 5. After being sprayed by the spray module 9, the residue adhering to the inner wall of the filter cylinder 5 will fall off due to the impact of the water flow. However, some of the filtered substances in the sewage will adhere to the inner wall of the filter cylinder 5 due to their strong viscosity and are difficult to be washed away by the water flow. At this time, when the frame 4 rotates, the frame 4 drives the filter cylinder 5 to rotate together through the friction between the frame 4 and the filter cylinder 5. When the filter cylinder 5 rotates, it drives the reciprocating screw 61 and the first gear 62 to rotate together through the first gear ring 63, so that the second gear 64 is always rotating. In this state, when the second toothed ring 65 of the frame 4 meshes with the second gear 64, the difference in gear ratio will cause a speed difference in the rotation of the frame 4 and the filter cartridge 5. This will cause the frame 4, which is fixed to the second toothed ring 65, to rotate at a lower speed than the filter cartridge 5, which is fixed to the first toothed ring 63. Originally, the frame 4 and the filter cartridge 5 rotated at the same frequency due to friction. However, after the second toothed ring 65 of the frame 4 meshes with the second gear 64, the speed of the frame 4 will decrease for a short time. The frame 4 will then flip inside the filter cartridge 5, thereby scraping the inner wall of the filter cartridge 5. This will create a self-cleaning effect through friction between the frame 4 and the filter cartridge 5.

[0024] like Figures 6 to 8 , Figure 10 As shown, in a preferred embodiment of the present invention, the scraping assembly 7 includes a magnetic slide 71 that slides with the reciprocating lead screw 61. Universal wheels 72 are symmetrically rotatably connected to the surface of the magnetic slide 71, and both universal wheels 72 roll in contact with the surface of the filter cartridge 5. A sludge collection tray 73 is fixedly connected to the bracket 2, and a drain port is provided at the end of the sludge collection tray 73. A toothed rod 74 is fixedly connected to the top of the sludge collection tray 73, and a slide frame 75 is slidably connected to the toothed rod 74. A first drive shaft 76 rotatably connected to the side wall of the slide frame 75 meshes with the toothed rod 74. A toothed shaft 77 is rotatably connected inside the slide frame 75, meshing with the surface of the first drive shaft 76. A roller brush 78 is fixedly connected to the end side of the toothed shaft 77.

[0025] In practical application, the reciprocating screw 61 rotates, causing the magnetic slide 71 to slide horizontally above the filter cartridge 5. As the magnetic slide 71 slides, it is guided by magnetism to drive the slide 75 located inside the frame 4 to move laterally. When the slide 75 slides, the first drive shaft 76 on its side wall meshes with the upper surface of the slide 75 and rotates. During the rotation, the first drive shaft 76 meshes with the gear shaft 77, driving the roller brush 78 to rotate together. During the rotation, the roller brush 78 scrapes the inner wall of the filter cartridge 5 and cleans the gaps in the frame 4, preventing residue from adhering to the gaps in the frame 4 and failing to fall off, thus reducing the filtration effect of the equipment.

[0026] The residue washed down by the water flow inside the filter cartridge 5, and the residue scraped down by the rotating brush 78, will fall into the sludge collection tray 73 and be discharged to the drain outlet as the water in the sludge collection tray 73 flows.

[0027] like Figure 8 and Figure 10 As shown, in a preferred embodiment of the present invention, magnetic plates with opposite magnetic poles are installed on the adjacent sides of the magnetic slide 71 and the slide 75, and the scraper on the surface of the roller brush 78 is bent, and the scraper on the surface of the roller brush 78 abuts against the inner wall of the filter cartridge 5.

[0028] like Figure 4 As shown, in a preferred embodiment of the present invention, the spray modules 9 are symmetrically distributed inside the housing 1, and multiple spray nozzles are installed on the surface of the spray modules 9, all of which face the sludge collection tray 73.

[0029] like Figures 7 to 11 As shown, in a preferred embodiment of the present invention, the crushing component 8 includes a round rod 81 located inside the outer shell 1 and rotatably connected to the support 2. A transmission gear 82 is fixedly connected to the surface of the round rod 81. A main gear disk 83 fixedly connected to the inner wall of the frame 4 meshes with the transmission gear 82. A limiting ring 84 fixedly connected to the inner wall of the frame 4 slides with the outer wall of the round rod 81. A protrusion 85 fixedly connected to the inner wall of the frame 4 abuts against the end side of the round rod 81. A turntable 86 is rotatably connected to the support 2. A first spring 87 is fixedly connected between the end of the round rod 81 and the turntable 86. A transmission gear disk 89 is rotatably connected to the support 2. A first gear disk 88 fixedly connected to the surface of the round rod 81 meshes with the transmission gear disk 89. A second gear disk 810 is rotatably connected to the round rod 81 and meshes with the transmission gear disk 89.

[0030] like Figures 7 to 11 As shown, in a preferred embodiment of the present invention, a first grinding disc 811 is fixedly connected to the side of the second gear disc 810 near the second grinding disc 812. A sleeve 813 is rotatably connected to the surface of the first grinding disc 811. An eccentric pump 814 is installed at the bottom of the sleeve 813. A second drive shaft 815 is rotatably connected to the middle of the eccentric pump 814. The end of the second drive shaft 815 away from the eccentric pump 814 is rotatably connected to the outer wall of the bracket 2. A drive belt 816 is connected between the round rod 81 and the second drive shaft 815. A suction cup 817 is fixedly connected to the bottom of the eccentric pump 814. A spiral guide plate 818 is fixedly connected to the inner wall of the frame 4.

[0031] In practical application, the skeleton 4 rotates, causing the spiral guide plate 818 to rotate as well. During the rotation, the spiral guide plate 818 pushes the solid residue deposited at the bottom of the skeleton 4 into the skeleton 4, thereby moving the solid residue to below the suction cup 817. The skeleton 4 rotates, causing the main gear disk 83 and the protrusion 85 to rotate as well. When the main gear disk 83 rotates, it drives the transmission gear 82 to rotate through meshing. When the round rod 81 and the transmission gear 82 rotate, they drive the second transmission shaft 815 to rotate through the transmission belt 816. After the second transmission shaft 815 rotates eccentrically inside the eccentric pump 814, it generates an upward suction force, causing the solid residue deposited at the bottom of the skeleton 4 to be sucked into the suction cup 817 and then into the sleeve 813 through the eccentric pump 814. At this time, since the first grinding disc 811 and the second grinding disc 812 are both located inside the sleeve 813, the solid residue will be located between the first grinding disc 811 and the second grinding disc 812 after being sucked into the sleeve 813.

[0032] When the first toothed disc 88 rotates together with the round rod 81, it will drive the second toothed disc 810 to rotate together through the transmission toothed disc 89, so that the first grinding disc 811 and the second grinding disc 812 rotate in opposite directions. When the end side of the round rod 81 is squeezed by the protrusion 85 when the frame 4 rotates, the round rod 81 will slide towards the side closer to the bracket 2. The first spring 87 is compressed and elastically contracts, and the distance between the first grinding disc 811 and the second grinding disc 812 is shortened, so that the solid residue between the first grinding disc 811 and the second grinding disc 812 is ground and crushed. The crushed residue will fall back into the filter cartridge 5 through the water inlet of the sleeve 813, so that the solid residue will not always remain in the frame 4, reducing the wear caused by the solid residue rolling inside the filter cartridge 5 when the filter cartridge 5 rotates, and preventing the residue from clogging inside the filter cartridge 5 and affecting the filtration efficiency of the filter cartridge 5.

[0033] like Figure 11 As shown, in a preferred embodiment of the present invention, when the end side of the round rod 81 abuts against the protrusion 85, the adjacent sides of the first grinding disc 811 and the second grinding disc 812 are in contact, the edges of the first grinding disc 811 and the second grinding disc 812 are chamfered, and the outer wall of the sleeve 813 is uniformly provided with water permeable holes.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
