Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment devices, and in particular to a soft ceramic sewage treatment device. Background Technology

[0002] Soft ceramics is a flexible building decoration material made primarily from inorganic mineral powders with the addition of appropriate polymer binders. It is formed through a specific molding process and then baked at a relatively low temperature to solidify. The core production process involves mixing and stirring the powdered raw materials and binders to form a plastic blank, which is then pressed or extruded into sheets. Finally, heat is used in the drying tunnel to promote polymer cross-linking and curing, giving the material its final structural strength and flexibility. Products made using this process combine the decorative effects of traditional ceramics with the lightweight, flexible, and easy-to-work characteristics. It can achieve rich surface textures and color imitations (such as imitation stone and leather textures), meeting diverse decorative needs.

[0003] However, in the upstream processes of soft porcelain production, such as raw material processing (crushing, screening, and batching) and molding, a large amount of fine mineral dust particles are inevitably generated. To effectively control dust pollution in the production environment, water spraying or water curtains are commonly used for dust absorption and suppression, resulting in the generation of a large amount of wastewater containing fine mineral powder. To achieve water resource recycling and reduce production costs and environmental pressure, existing technologies usually rely on wastewater treatment systems. The common treatment method is to first introduce the wastewater into a settling tank, where gravity causes the heavier particles to initially settle and separate. The supernatant is then finely filtered through a filter screen (or filter cloth) to remove residual fine suspended solids. Only purified water can be reused. However, due to the fine particle size, irregular shape, and possible stickiness of the particles contained in the wastewater, these microparticles are more likely to adhere to and remain in the pores or surface of the filter screen when entering the filtration stage. As the operating time accumulates, these particles gradually accumulate on the filter screen, eventually leading to a sharp reduction in the effective filtration area of ​​the filter screen, a significant increase in filtration resistance, and even severe clogging. This results in a significant decrease in filtration efficiency, making it impossible to guarantee stable water treatment capacity and reclaimed water quality. This forces frequent cleaning or replacement of the filter screen, which not only increases maintenance costs but also affects the continuity and stability of production. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a soft ceramic wastewater treatment device, which solves the problems of easy clogging of filter screens due to the characteristics of soft ceramic particles, which cannot guarantee stable water treatment capacity and recycled water quality, increases maintenance costs and frequency, and affects the continuity and stability of production.

[0005] According to an embodiment of the present invention, a soft ceramic wastewater treatment device includes:

[0006] A settling tank, wherein an agitator is rotatably mounted inside the settling tank, and a drive source capable of driving the agitator to rotate is fixedly mounted on the top of the settling tank, and a water outlet pipe is connected to the side wall of the settling tank near the top.

[0007] The purification tank is divided into several purification channels by a partition plate. The two outermost purification channels are respectively fixedly provided with inlet and outlet water inlets that connect the inside and outside. The inlet water inlets are connected to the outlet water pipe. The partition plate is provided with a water outlet that can connect to the adjacent purification channels. A filter screen is fixedly provided at the water outlet. A brush plate is rotatably provided inside the purification channel. Several brush bristles are fixedly provided at the end of the brush plate. The brush bristles abut against the filter screen when rotating.

[0008] The technical principle of this utility model is as follows: Soft porcelain wastewater is introduced into a settling tank. After adding flocculant, the drive source is turned on to drive the stirring blades to agitate the wastewater, accelerating the settling of particulate dust in the wastewater. The clear liquid on the upper layer of wastewater overflows into the purification tank through the outlet pipe. The clear liquid will start from the purification channel where the inlet is located, pass through the filter screen step by step, and enter the adjacent purification channel until it finally enters the purification channel where the outlet is located and is discharged from the outlet. When the filter screen becomes clogged, the brush plate is manually rotated so that the bristles on the brush plate can contact and abut against the filter screen to brush and wash the filter screen, thereby brushing off the microparticles adhering to the filter screen, quickly restoring the filter screen's filtration function, significantly extending the frequency of filter screen cleaning or replacement, and ensuring the continuity and stability of production.

[0009] Furthermore, the water inlets are located near the wall of the purification tank, and adjacent water inlets are staggered on both sides of the partition plate.

[0010] Furthermore, the brush plate includes a rotating rod and a plurality of cleaning plates fixedly arranged around the rotating rod. A plurality of bristles are evenly fixedly connected to the outer side of the cleaning plates, and the inner wall of the purification pool is provided with a clearance groove for the cleaning plates to rotate.

[0011] Furthermore, a rotating seat is fixedly installed on the wall of the purification tank on the water inlet side of the filter screen, and the rotating rod is rotatably connected to the bottom of the rotating seat. A stable seat is also fixedly installed at the bottom of the purification channel for the bottom of the rotating rod to be embedded and rotate relative to it.

[0012] Furthermore, the bottom of the purification channel gradually rises from the rotating rod to the distal side, and an inclined guide plate is fixedly installed at the bottom of the purification channel near the rotating rod, with the end of the guide plate pointing towards the cleaning plate.

[0013] Furthermore, the water inlet is fixedly located on the higher side of the purification channel, and the water outlet is fixedly located on the lower side of the purification channel.

[0014] Furthermore, the filter screen is arc-shaped and coaxial with the rotating rod, and fixing strips are fixedly provided on both sides of the filter screen. The partition plate and the inner wall of the purification tank near the water outlet are respectively provided with sliding grooves that allow the fixing strips to be embedded and slide relative to each other.

[0015] Furthermore, the purification channel is provided with a slag collection trough at the bottom of the brush plate, and a slag discharge pipe connecting the inside and outside is fixedly provided on one side of the slag collection trough. A second drain valve that can control its opening and closing is fixedly provided on the slag discharge pipe.

[0016] Furthermore, the lower part of the settling tank is provided with a conical sludge collection section, and a drain pipe is connected to the bottom of the sludge collection section.

[0017] Furthermore, the drive source includes a motor, which is fixedly mounted on the top of the settling tank via a mounting plate, and the output shaft of the motor is fixedly connected to the stirring blade.

[0018] Compared with existing technologies, this utility model has the following advantages: the mechanical stirring of the stirring blades in the settling tank accelerates flocculation and sedimentation, effectively reducing the concentration of suspended particles entering the purification tank. Combined with multi-stage series purification channels and filter screens for step-by-step fine filtration, the solid-liquid separation effect is significantly improved. Furthermore, the rotating brush plate drives the bristles to perform in-situ physical brushing of the clogged filter screen, quickly removing adhesive microparticles from the surface and pores of the filter screen, thereby greatly extending the filter screen cleaning or replacement cycle and ensuring the continuity and stability of production.

Detailed Implementation

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-2 and Figure 4 As shown in the figure, this utility model embodiment proposes a soft ceramic wastewater treatment device, including a settling tank 1. Several supporting legs 16 are fixedly arranged around the bottom of the settling tank 1 for stable support. An inlet pipe 14 connecting the inside and outside is fixedly arranged on the side wall of the settling tank 1 for wastewater introduction. A flocculant inlet pipe 15 connecting the inside and outside is also fixedly arranged on the side wall of the settling tank 1. The flocculant inlet pipe 15 is connected to a flocculant storage tank or tonne container and is equipped with a delivery pump to control the input of flocculant, thereby accelerating the aggregation and settling of particulate matter. A cone-shaped structure is provided at the bottom of the settling tank 1. The sedimentation tank 1 has a narrowed-diameter collection section 11, which facilitates the settling of particulate matter in the wastewater and its accumulation at the bottom center. The inclined surface increases the contact area with the particles, further accelerating settling. A drain pipe 111 is connected to the bottom of the collection section 11, and a first drain valve 112 is fixedly installed on the drain pipe 111 to control its opening and closing. Opening the first drain valve 112 quickly discharges the sludge that has settled in the sedimentation tank 1. Compared to traditional sedimentation tanks that can only passively remove sludge periodically using a pump, the sedimentation tank 1 offers more efficient and convenient sludge removal.

[0027] like Figure 1-2As shown, further, a stirring blade 13 is rotatably arranged inside the settling tank 1. The stirring blade 13 includes a stirring shaft and several stirring rods fixedly arranged around the stirring shaft. The stirring rods can rotate to form a vortex, so that the flocculant and particles can fully contact each other, significantly improving the floc formation efficiency and accelerating the settling speed. A drive source that can drive the stirring blade 13 to rotate is fixedly arranged on the top of the settling tank 1. The drive source includes a motor 131 or a motor and other mechanisms that can drive rotation. In this embodiment, the drive source is a motor 131. The motor 131 is fixedly arranged on the top of the settling tank 1 through a mounting plate 132. The output shaft of the motor 131 is coaxially fixedly connected to the stirring shaft of the stirring blade 13. A water outlet pipe 12 is connected to the side wall of the settling tank 1 near the top. The water outlet pipe 12 is used for the overflow of the upper clear liquid of the sewage for further purification treatment of the sewage.

[0028] like Figure 1-2 As shown in the figure, the soft porcelain wastewater treatment device proposed in this embodiment of the present invention also includes a purification tank 2. The purification tank 2 is divided into several elongated purification channels 24 by a partition plate 23. The two outermost purification channels 24 are respectively fixedly provided with inlet 21 and outlet 22 connecting the inside and outside. The inlet 21 and the outlet pipe 12 are interconnected by a water supply pipe 17. A stop valve 171 that can control its opening and closing is fixedly provided on the water supply pipe 17. The partition plate 23 is provided with a through port 231 that can connect adjacent purification channels 24. A filter screen 3 is fixedly installed at the water inlet 231. After the wastewater enters from the water inlet 21, it will be filtered by the filter screen 3 step by step and enter the next purification channel 24 until it is finally discharged from the water outlet 22 for reuse. A brush plate 4 is rotatably installed in each purification channel 24. The brush plate 4 is located close to the filter screen 3. Several bristles 431 are fixedly installed at the end of the brush plate 4. When rotating, the bristles 431 contact and abut against the filter screen 3. By rotating the brush plate 4, the filter screen 3 can be brushed and washed, thereby quickly brushing off the micro particles adhering to the filter screen 3 and keeping the surface of the filter screen 3 clean.

[0029] The technical principle of this utility model is as follows: Soft porcelain wastewater is introduced into the settling tank 1 through the inlet pipe 14. After flocculant is added through the flocculant inlet pipe 15, the motor 131 is turned on to drive the stirring blades 13 to stir the wastewater, accelerating the settling of particulate dust in the wastewater. The clear liquid on the upper layer of wastewater overflows into the purification tank 2 through the outlet pipe 12. The clear liquid will start from the purification channel 24 where the inlet 21 is located, pass through the filter screen 3 step by step, and enter the next adjacent purification channel 24 until it finally enters the purification channel 24 where the outlet 22 is located and is discharged from the outlet 22. When the filter screen 3 becomes clogged, the brush plate 4 is manually rotated so that the bristles 431 on the brush plate 4 can contact and abut against the mesh surface of the filter screen 3 to brush the filter screen 3, thereby brushing off the microparticles adhering to the filter screen 3, quickly restoring the filtration function of the filter screen 3, greatly extending the cleaning or replacement frequency of the filter screen 3, and ensuring the continuity and stability of production.

[0030] This invention accelerates flocculation and sedimentation through mechanical stirring of the stirring blades 13 in the settling tank 1, effectively reducing the concentration of suspended particles entering the purification tank 2. Combined with multi-stage series purification channels 24 and filter screens 3, it performs step-by-step fine filtration, significantly improving the solid-liquid separation effect. Furthermore, the rotatable brush plate 4 drives the bristles 431 to perform in-situ physical brushing of the clogged filter screen 3, quickly removing adhesive microparticles from the surface and pores of the filter screen 3, thereby greatly extending the cleaning or replacement cycle of the filter screen 3 and ensuring the continuity and stability of production.

[0031] like Figure 1-4 As shown, according to another embodiment, the water outlet 231 is further located near the wall of the purification tank 2, and adjacent water outlets 231 are staggered on both sides of the partition plate 23. Specifically, the water outlet 231 is fixedly installed at the connection between the partition plate 23 and the wall of the purification tank 2, and the water outlets 231 on adjacent partition plates 23 are arranged alternately on the left and right, so that the purification channel 24 can be connected end to end to form an S-shaped water flow path. Through the above arrangement, the sewage flow distance is greatly extended, thereby enhancing the sedimentation effect, achieving a large treatment capacity in a small space, reducing the equipment footprint cost, and increasing the total area of ​​the filter screen 3. The sewage will be filtered through the multi-stage purification channel 24. Each time it passes through the filter screen 3, large particles are intercepted first, and the remaining finer particles enter the next stage, so that the final effluent turbidity is significantly reduced and the quality of the recycled water is more stable.

[0032] like Figure 1-4As shown, in this embodiment, the brush plate 4 further includes a rotating rod 42 and a plurality of cleaning plates 43 fixedly arranged around the rotating rod 42. A plurality of bristles 431 are uniformly fixedly connected to the outer side of the cleaning plates 43. The bristles 431 are made of wear-resistant, corrosion-resistant and elastic materials such as synthetic nylon, polypropylene or polyester PET. The inner wall of the purification pool 2 is provided with a clearance groove 25 for the rotation of the cleaning plates 43 to avoid the rotation path of the cleaning plates 43. Specifically, a rotating seat 41 is fixedly arranged on the water inlet side of the filter screen 3 on the wall of the purification pool 2. The rotating seat 41 is fixedly connected to the top of the purification pool 2 wall by bolts. The rotating rod 42 is rotatably connected to the bottom of the rotating seat 41. A stabilizing seat 44 is also fixedly arranged at the bottom of the purification channel 24 for the bottom of the rotating rod 42 to be embedded and rotate relative to it. Optionally, a motor or electric motor 131 can also be fixedly arranged on the top of the rotating seat 41 to drive the rotating rod 42 to rotate, replacing manual operation and increasing the convenience and automation of the device.

[0033] like Figure 4-5 As shown, in this embodiment, the bottom of the purification channel 24 gradually rises from the rotating rod 42 to the distal side, that is, the bottom surface of the purification channel 24 is set as an inclined surface. The water inlet 21 is fixedly set on the higher side of the purification channel 24, and the water outlet 22 is fixedly set on the lower side of the purification channel 24. An inclined guide plate 26 is fixedly set at the bottom of the purification channel 24 near the rotating rod 42. The guide plate 26 forms an acute angle with the water flow direction, and the end of the guide plate 26 points to the cleaning plate 43. The guide plate 26 can change the water flow direction, so that the water flowing down the inclined surface can directly impact the cleaning plate 43, thereby driving the rotating rod 42 to rotate. The impact generated by the gravity of the water flow replaces the manual or external mechanical drive of the rotating rod 42 to rotate, realizing self-drive without power. The bristles 431 rotate continuously with the water flow, and the particles are brushed away from the filter screen 3 before they are caking. It changes from passive cleaning after clogging to continuous dynamic anti-clogging. The stronger the water flow, the stronger the scouring force. The speed of the brush bristles 431 automatically increases to adapt to the clogging needs. Preferably, the end of the guide plate 26 faces the side where the filter screen 3 is located, and the inclined bottom surface accelerates the flow of sewage. The water flow with enhanced impact drives the cleaning plate 43 to rotate and collide directly with the filter screen 3. The water flow with small particles can directly pass through the filter screen 3 and enter the next stage of purification channel 24. Large particles of dirt will be intercepted by the filter screen 3 and brushed away by the cleaning plate 43 to the side away from the filter screen 3. The subsequent continuous water flow impact will further disperse the particles adhering to the surface of the filter screen 3, prevent the particles from depositing and hardening on the surface of the filter screen 3, maintain the permeability of the filter screen 3, and reduce the cleaning load of the subsequent brush bristles 431. The water flow impact and the rotating brush bristles 431 form a dual effect of "physical scouring + mechanical scraping", which performs three-dimensional cleaning of the pores of the filter screen 3, avoids clogging during the gap period of intermittent cleaning, greatly increases the service life of the filter screen 3, and reduces the frequency of filter screen 3 replacement and cleaning.

[0034] like Figure 4-5 As shown, according to another embodiment, the filter screen 3 is further curved and coaxial with the rotating rod 42, so that the bristles 431 can clean the filter screen 3 more thoroughly when rotating. Preferably, the mesh diameter of the filter screen 3 can be reduced sequentially along the water flow path to improve the filtration accuracy step by step. Fixing strips 31 are fixedly provided on both sides of the filter screen 3. The partition plate 23 and the inner wall of the purification tank 2 near the water outlet 231 are respectively provided with sliding grooves 27 that allow the fixing strips 31 to be embedded and slide relative to each other. The filter screen 3 can be fixed by common fixing structures such as buckles, threads or pins. Those skilled in the art can choose according to actual needs, which will not be elaborated here. The filter screen 3 can be quickly installed and disassembled by sliding up and down, further increasing the convenience of this device.

[0035] like Figure 4-5 As shown, according to another embodiment, further, the purification channel 24 is provided with a slag collection trough 28 at the bottom of the brush plate 4. The slag collection trough 28 is used to collect and settle sludge particles that have not been filtered by the filter screen 3. A slag discharge pipe 29 communicating with the inside and outside is fixedly provided on one side of the slag collection trough 28. A second drain valve 291 that can control its opening and closing is fixedly provided on the slag discharge pipe 29.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
