Description

Technical Field

[0001] This utility model relates to the field of ceramic machinery, specifically to a novel ceramic clay wastewater recycling device. Background Technology

[0002] Ceramic production and post-processing involve large water consumption. Industrial water use in ceramic factories consists of two parts: one is the floor washing water in the large grinding, powder making, and powder conveying workshops, and the other is the water used for polishing and edge grinding. Each of these processes generates a large amount of wastewater. Currently, the main method for wastewater treatment is to introduce the wastewater into a sedimentation tank for sedimentation. However, this method has a slow sedimentation rate, and bacteria easily grow at the bottom of the tank, producing odors. It is not conducive to clean production and small-scale production, and it cannot achieve water recycling and conservation.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0004] The purpose of this invention is to provide a novel ceramic clay wastewater recycling device that is highly efficient and saves water.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A novel ceramic clay wastewater recycling device includes a wastewater tank and a filtration mechanism for filtering the wastewater. The filtration mechanism has an inlet and an outlet, with the inlet connected to the wastewater tank. It also includes a water storage tank connected to the outlet and storing clean water. The filtration mechanism includes a spiral extrusion cylinder, a spiral extrusion rod coaxially located inside the spiral extrusion cylinder, and a motor for driving the spiral extrusion rod. The spiral extrusion rod includes a rotating shaft and a spiral housing fitted outside the rotating shaft. The spiral housing is provided with filter holes, and a water passage gap is formed between the spiral housing and the rotating shaft for the filtered clean water to pass through. Multiple spaced support rods are connected between the spiral housing and the rotating shaft, and the outlet is connected to the water passage gap.

[0007] The spiral extrusion cylinder is gradually inclined downward from the inlet to the outlet. There is a filter gap between the spiral shell and the spiral extrusion cylinder. The inlet is connected to the filter gap and is connected to the wastewater tank by an inlet pipe. The inlet pipe is equipped with a water pump. The outlet is connected to the water passage gap and is connected to the water storage tank by an outlet pipe.

[0008] It also includes a mud outlet located on the spiral shell for the filtered ceramic mud to flow out. The mud outlet is located at the lower end of the spiral extrusion cylinder and is connected to the filtration gap.

[0009] The spiral housing includes a spiral protruding filter section in a spiral shape and a fine-diameter filter section connected between the spiral protruding filter sections; a support rod is connected to the inner surface of at least one of the fine-diameter filter section and the spiral protruding filter section.

[0010] The circumferential surface of the rotating shaft has a positioning groove for inserting and positioning the support rod.

[0011] The positioning groove is a strip-shaped groove that extends along the axis of the rotating shaft and passes through to the end of the rotating shaft.

[0012] The filtration mechanism is equipped with a bracket; the bracket has a first support part supporting the upper end of the spiral extrusion cylinder and a second support part supporting the lower end of the spiral extrusion cylinder; the motor is located in the first support part and connected to the upper end of the rotating shaft.

[0013] The upper end of the spiral extruder is connected to the first support part through a first connecting pipe. The diameter of the first connecting pipe is the same as the diameter of the fine diameter filter part. The upper end of the first connecting pipe is fixedly connected to the first support part through a flange. The lower end of the spiral extruder is connected to the second support part through a second connecting pipe. The diameter of the second connecting pipe is the same as the diameter of the fine diameter filter part. The lower end of the second connecting pipe is fixedly connected to the second support part through a flange.

[0014] The flange includes an inner ring portion on the inner ring and an outer ring portion on the outer ring; the inner ring portion is connected to the rotating shaft via a bearing, the outer ring portion is sealed to the spiral extrusion cylinder, and the outer ring portion is locked to the bracket with bolts; there is an annular gap between the inner ring portion and the outer ring portion that corresponds to the water passage gap, and an annular support rod is connected between the inner ring portion and the outer ring portion, and the annular gap is connected to the water outlet pipe.

[0015] By adopting the above technical solution, the novel ceramic clay wastewater recycling device of this utility model breaks through the traditional wastewater treatment device structure. In actual operation, the water pump transports the wastewater in the wastewater pool to the inlet through the inlet pipe and enters the space between the spiral extrusion cylinder and the spiral shell. The wastewater is filtered by the filter holes of the spiral shell. The clean water enters the water passage gap and flows out from the outlet to the storage tank for recycling. The filtered clay particles remain outside the spiral shell to form ceramic mud, which is spirally transported by the spiral shell. Specifically, the motor drives the rotating shaft to rotate the spiral shell. The three-dimensional spiral shape of the spiral shell agitates the wastewater, allowing the wastewater to fully and efficiently contact the large spiral surface area of ​​the spiral shell. At the same time, the high-speed flushing of the relative water flow can also avoid clogging of the holes, ensuring full and efficient filtration. Moreover, the rotation speed and rotation direction of the spiral shell can be adjusted to adapt to the wastewater concentration and filtration requirements. For example, if the wastewater concentration is high, the rotation speed can be reduced, the reverse direction can be reversed, or the forward and reverse rotation can be alternated. If the concentration is low, the rotation speed can be increased. The ceramic clay can be continuously discharged and collected, or the outlet can be temporarily closed. Once the clay has accumulated to a certain consistency and quantity in the filtration gap, the outlet can be reopened to obtain ceramic clay of the appropriate consistency. The filtered clay can also be collected and reused, making it environmentally friendly, resource-saving, and cost-effective. Compared with existing technologies, this novel ceramic clay wastewater recycling device has advantages such as high-efficiency recycling and water conservation. Attached Figure Description

[0026] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0027] This utility model discloses a novel ceramic clay wastewater recycling device, such as... Figure 1-6As shown, the system includes a wastewater tank 1 and a filtration mechanism 2 for filtering wastewater. The filtration mechanism 2 has an inlet 21 and an outlet 22, with the inlet 21 connected to the wastewater tank 1. It also includes a water storage tank 3 connected to the outlet 22 and storing clean water. The filtration mechanism 2 includes a spiral extrusion cylinder 23, a spiral extrusion rod 24 coaxially located inside the spiral extrusion cylinder 23, and a motor 25 for driving the spiral extrusion rod 24. The spiral extrusion rod 24 includes a rotating shaft 241 and a spiral housing 242 fitted outside the rotating shaft 241. The spiral housing 242 is provided with filter holes. A water passage gap 2421 is formed between the spiral housing 242 and the rotating shaft 241 for filtered clean water to pass through. Multiple spaced support rods 2422 are connected between the spiral housing 242 and the rotating shaft 241. The outlet 22 is connected to the water passage gap 2421, and the gaps between the support rods 2422 allow clean water to pass through. In actual operation, the water pump 271 transports wastewater from the wastewater pool 1 to the inlet 21 through the inlet pipe 27, and the wastewater enters between the spiral extrusion cylinder 23 and the spiral shell 242. The wastewater is filtered by the filter holes of the spiral shell 242, and the clean water enters the water passage gap 2421 and flows out from the outlet 22 to the storage tank 3 for recycling. The filtered porcelain clay particles remain outside the spiral shell 242 to form porcelain mud, which is spirally transported by the spiral shell 242. Specifically, the motor 25 drives the rotating shaft 241 to rotate the spiral shell 242. The three-dimensional spiral shape of the spiral shell 242 agitates the wastewater, allowing the wastewater to fully and efficiently contact the large spiral surface area of ​​the spiral shell 242. At the same time, the high-speed flushing of the relative water flow can also avoid clogging of the holes, ensuring full and efficient filtration. Moreover, the rotation speed and rotation direction of the spiral shell 242 can be adjusted to adapt to the wastewater concentration and filtration requirements. For example, if the concentration of porcelain clay in the wastewater is high, the rotation speed can be reduced, the rotation can be reversed, or the forward and reverse rotation can be alternated. If the concentration is low, the rotation speed can be increased. The porcelain clay can be continuously discharged and collected, or the clay outlet 2423 can be opened temporarily. When the porcelain clay accumulates a certain consistency and amount in the filtration gap 26, the clay outlet 2423 can be opened again to obtain porcelain clay of the corresponding consistency. The filtered porcelain clay can also be collected and reused, which is environmentally friendly, saves resources and reduces costs. The specific structure can be as follows: the spiral extrusion cylinder 23 is gradually inclined downward from the inlet 21 to the outlet 22, and the wastewater can flow naturally from top to bottom through the spiral shell 242 for filtration. There is a filtration gap 26 between the spiral shell 242 and the spiral extrusion cylinder 23. The inlet 21 is connected to the filtration gap 26 and is connected to the wastewater pool 1 by an inlet pipe 27. The inlet pipe 27 is equipped with a water pump 271, which pumps the wastewater out and transports it to the inlet 21 through the inlet pipe 27. The outlet 22 is connected to the water passage gap 2421 and is connected to the water storage tank 3 by an outlet pipe 28. The filtered clean water enters the water storage tank 3 through the outlet pipe 28 from the outlet 22 for storage and subsequent reuse.A further specific structure includes a mud outlet 2423 located on the spiral shell 242 for the filtered porcelain mud to flow out. The mud outlet 2423 is positioned downwards at the lower end of the spiral extrusion cylinder 23 and communicates with the filtration gap 26. The filtered porcelain mud is gradually conveyed downwards by the spiral shell 242 and extruded and collected from the mud outlet 2423. A further specific structure includes a spiral protruding filter section 2424 in a spiral shape, and a fine-diameter filter section 2425 connected between the spiral protruding filter sections 2424. A support rod 2422 is connected to the inner surface of at least one of the fine-diameter filter section 2425 and the spiral protruding filter section 2424, meaning that the interior of the fine-diameter filter section 2425 and at least one of the spiral protruding filter section 2424 are supported by the support rod 2422, ensuring the stability of the spiral shell 242 structure. The spiral protruding filter section 2424 and the fine-diameter filter section 2425 are integrally pressed from hard steel plates, or welded from hard steel plates. A mud collection cart is installed below the mud outlet 2423. The mud collection cart has rollers, and the rollers are equipped with tracks. The fine-diameter filter section 2425 at the upper end of the spiral shell 242 has a sealing part corresponding to the cavity of the first connecting pipe 231 to prevent clean water from flowing upward. The sealing part has a first sealing protrusion corresponding to the inner end of the first connecting pipe 231 to prevent wastewater from flowing upward. The fine-diameter filter section 2425 at the lower end of the spiral shell 242 has a second sealing protrusion corresponding to the inner end of the second connecting pipe 232 to prevent wastewater and porcelain mud from entering the second connecting pipe 232 and contaminating the clean water. A first glass fiber pad is placed between the first sealing protrusion and the inner end of the first connecting pipe 231, and a second glass fiber pad is placed between the second sealing protrusion and the inner end of the second connecting pipe 232. The glass fiber pads have the function of reducing friction and blocking porcelain mud particles.

[0028] More preferably, the circumferential surface of the rotating shaft 241 is formed with a positioning groove 2411 for inserting and positioning the support rod 2422. The positioning groove 2411 allows the support rod 2422 to be inserted and positioned, so that the spiral shell 242 rotates synchronously with the rotating shaft 241, and facilitates installation. Specifically, the positioning groove 2411 can be a strip-shaped groove extending along the axial direction of the rotating shaft 241 and penetrating to the end of the rotating shaft 241. This allows the rotating shaft 241 to be directly fitted into the spiral shell 242, while simultaneously aligning the support rod 2422 with the positioning groove 2411, directly achieving the insertion of the support rod 2422 into the positioning groove 2411 to ensure synchronous rotation and positioning, without having to connect each support rod 2422 to the rotating shaft 241 individually; during disassembly, the rotating shaft 241 can be directly pulled out, without having to disassemble each support rod 2422 to the rotating shaft 241 individually, making it convenient and practical.

[0029] To further preferably support the main components of the spiral mechanism, the filter mechanism 2 is equipped with a bracket 4; the bracket 4 has a first support portion 41 supporting the upper end of the spiral extrusion cylinder 23 and a second support portion 42 supporting the lower end of the spiral extrusion cylinder 23; the motor 25 is located on the first support portion 41 and connected to the upper end of the rotating shaft 241. The motor 25 is positioned at the upper end, making it less likely to come into contact with the water flow, thus ensuring stable and continuous operation of the motor 25. To achieve the specific connection between the spiral extrusion cylinder 23 and the support 4, the specific structure can be as follows: the upper end of the spiral extrusion cylinder 23 is connected to the first support part 41 through the first connecting pipe 231, the diameter of the first connecting pipe 231 is the same as the diameter of the fine diameter filter part 2425, and the upper end of the first connecting pipe 231 is fixedly connected to the first support part 41 through the flange 233; the lower end of the spiral extrusion cylinder 23 is connected to the second support part 42 through the second connecting pipe 232, the diameter of the second connecting pipe 232 is the same as the diameter of the fine diameter filter part 2425, and the lower end of the second connecting pipe 232 is fixedly connected to the second support part 42 through the flange 233. To achieve end positioning connection of the rotating shaft 241 and facilitate the direct flow of clean water from the water passage gap 2421 into the second connecting pipe 232 and out through the annular gap 2333 to the outlet pipe 28, the specific structure can be as follows: the flange 233 includes an inner ring portion 2331 on the inner ring and an outer ring portion 2332 on the outer ring; the inner ring portion 2331 is connected to the rotating shaft 241 via a bearing, the outer ring portion 2332 is sealed to the spiral extrusion cylinder 23, and the outer ring portion 2332 is bolted to the bracket 4; there is an annular gap 2333 between the inner ring portion 2331 and the outer ring portion 2332, corresponding to and communicating with the water passage gap 2421; an annular support rod 2334 connects the inner ring portion 2331 and the outer ring portion 2332, and the annular gap 2333 communicates with the outlet pipe 28. The gap between the annular support rods 2334 allows clean water to pass through. Specifically, the second connecting pipe 232 is connected to the main body of the spiral extrusion cylinder 23 via a flange 233. That is, the lower end of the spiral extrusion cylinder 23 has a disassembly cover, through which the internal structure can be disassembled and assembled.
