Description

Technical Field

[0001] This utility model belongs to the field of sedimentation tanks, and in particular relates to an integrated inclined plate cleaning device for sedimentation tanks in water plants. Background Technology

[0002] Integrated water treatment plants, due to their relatively small scale, often employ inclined plate sedimentation tanks that require minimal floor space but handle high treatment loads. However, after a period of operation, sludge gradually accumulates on the surface of the inclined plates, affecting the effluent quality. When the influent flow rate changes, the deposited sludge is disturbed, further exacerbating the deterioration in effluent quality. Furthermore, the accumulated sludge shortens the lifespan of the inclined plates. Traditional integrated sedimentation tanks lack a self-cleaning system for the inclined plates, requiring regular manual flushing. This manual flushing of the inclined pipes and plates significantly increases maintenance workload and operating costs. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned technical problems by providing an integrated inclined plate cleaning device for sedimentation tanks in water plants, which enables fully automatic cleaning of both sides of the inclined plates, thus solving the problems of low efficiency and safety hazards associated with traditional manual cleaning.

[0004] In view of this, the present invention provides an integrated inclined plate cleaning device for sedimentation tanks in water plants, comprising:

[0005] The sedimentation tank has connecting blocks fixed at both ends of its inner cavity at an incline, and an inclined plate is detachably connected between the two connecting blocks by bolts.

[0006] A cleaning mechanism, located at both ends of the connecting block, is used to clean the sludge from both ends of the inclined plate. The cleaning mechanism includes:

[0007] Two sets of connecting frames are fixed to both ends of the connecting block, and sliders are slidably connected to their inner cavities.

[0008] Two connecting shafts are rotatably connected between two sets of sliders via sealed bearings, and brush rollers are fixed on their outer sides.

[0009] The actuation component, located at the top of the two connecting frames, is used to drive the brush roller to move autonomously to clean the sludge on both ends of the inclined plate.

[0010] In this technical solution, a mechanical linkage structure of slider, brush roller and electric actuator is used to achieve fully automatic cleaning of the inclined plate on both sides, which solves the problems of low efficiency and safety hazards of traditional manual cleaning.

[0011] Furthermore, the pushing component includes an electric push rod fixedly connected to the top of the connecting frame, and the telescopic end of the electric push rod slides through the connecting frame and is fixedly connected to the slider.

[0012] In this technical solution, precise stroke control can be achieved through an electric actuator drive system.

[0013] Furthermore, an inlet is provided on one side of the sedimentation tank wall. The inlet is L-shaped and communicates with the inner cavity of the sedimentation tank. An outlet is provided on the upper side of the sedimentation tank at the end away from the inlet.

[0014] In this technical solution, the L-shaped inlet design creates a buffered water flow, which, together with the top outlet, forms a stable laminar flow, reducing disturbance to the deposited sludge.

[0015] Furthermore, the bristles of the brush roller are made of nylon material. Nylon bristles have the characteristics of acid and alkali corrosion resistance, high strength and smooth surface, which can effectively reduce sludge adhesion and improve cleaning efficiency.

[0016] In this technical solution, the corrosion resistance of nylon bristles enables the device to operate stably within the pH range of 2-11, and the smooth surface reduces the amount of sludge adhering to it.

[0017] Furthermore, a tooth is fixedly connected to the inner wall of one of the connecting frames in each group, and a gear is fixedly connected to the outer side of the connecting shaft on one side of the tooth, and the gear meshes with the tooth.

[0018] In this technical solution, the brush roller's rotation and translation are combined through a gear and tooth meshing structure, which improves the coverage of a single cleaning cycle and thus enhances the cleaning quality.

[0019] Furthermore, the connecting frame, teeth, and gears are all integrally molded from polytetrafluoroethylene.

[0020] In this technical solution, the use of polytetrafluoroethylene (PTFE) extends the lifespan of transmission components in wastewater environments and eliminates the need for additional lubrication and maintenance.

[0021] Furthermore, each of the connecting frames is fixedly connected to a water guide pipe, and the end of each water guide pipe near the brush roller is fixedly connected to multiple water spray heads, and each of the multiple water spray heads corresponds to the brush roller.

[0022] In this technical solution, the water spray head and the brush roller work together to form a dual cleaning mechanism of mechanical peeling and water rinsing, thereby improving the cleaning effect.

[0023] Furthermore, the bottom of the inner cavity of the sedimentation tank is fixedly connected to multiple V-shaped sludge collection covers, and the bottoms of the multiple sludge collection covers are connected by sludge discharge pipes, with a sludge pump installed at one end of the sludge discharge pipes.

[0024] In this technical solution, a V-shaped sludge collection hood is used in conjunction with a sludge pump to achieve continuous sludge discharge, avoiding the defect that the sedimentation tank must be shut down for sludge discharge every 2-3 days.

[0025] The beneficial effects of this utility model are:

[0026] 1. This utility model drives the component to slide the slider along the connecting frame, which in turn moves the brush roller along both ends of the inclined plate. The brush bristles on the brush roller contact and rub against the two ends of the inclined plate to achieve automatic sludge removal. This eliminates the need for manual entry into the sedimentation tank, solving the problems of traditional manual cleaning which requires downtime and is time-consuming, and reducing maintenance workload.

[0027] 2. In this utility model, when the brush roller moves, the gear meshes with the teeth to drive the connecting shaft to rotate, so that the brush roller can simultaneously achieve a compound motion of translation along the end face of the inclined plate and its own rotation. Thus, the rotating bristles can penetrate into the fine texture of the inclined plate surface, which improves the removal rate of stubborn sludge compared with simple translation cleaning and avoids manual secondary cleaning.

[0028] 3. This utility model connects to an external water source via a water pipe, allowing the spray nozzles to spray water onto the brush roller and the end face of the inclined plate. This softens the hardened sludge beforehand, making it easier for the brush roller to peel off the sludge. The water flow also washes away the sludge adhering to the surface of the brush roller, preventing the sludge from drying on the brush, maintaining the cleaning ability of the bristles, and extending the service life of the brush. Furthermore, the water spray can cover the edges of the inclined plate that are difficult for the brush roller to reach. Combined with the mechanical cleaning of the brush, this forms a composite cleaning of water rinsing and brushing, reducing cleaning dead corners, ensuring that the surface of the inclined plate is completely clean, and reducing the frequency of manual cleaning.

Additionally, features described with reference to certain examples may be combined in other examples.

[0039] Example 1:

[0040] like Figure 1-2 As shown, this utility model provides an integrated water plant sedimentation tank inclined plate cleaning device, including: a sedimentation tank 1, with connecting blocks 21 fixed at both ends of its inner cavity, and an inclined plate 2 detachably connected between the two connecting blocks 21 by bolts; a cleaning mechanism, located at both ends of the connecting blocks 21, for cleaning the sludge on both ends of the inclined plate 2, the cleaning mechanism including: two sets of connecting frames 3, respectively fixed at both ends of the connecting blocks 21, with sliders 35 slidably connected in their inner cavities; two connecting shafts 33, each rotatably connected between the two sets of sliders 35 via sealed bearings, with brush rollers 31 fixed on their outer sides; and a pushing component, located at the top of the two sets of connecting frames 3, for driving the brush rollers 31 to move autonomously to clean the sludge on both ends of the inclined plate 2.

[0041] By pushing the component drive slider 35 to slide along the connecting frame 3, the brush roller 31 is driven to move along both ends of the inclined plate 2. The sludge is automatically removed by the contact friction between the bristles on the brush roller 31 and the two ends of the inclined plate 2. There is no need for manual operation in the sedimentation tank 1, which solves the problem of traditional manual cleaning requiring downtime and long time consumption, and reduces the amount of maintenance work.

[0042] The pushing component includes an electric push rod 32 fixedly connected to the top of the connecting frame 3, and the telescopic end of the electric push rod 32 slides through the connecting frame 3 and is fixedly connected to the slider 35.

[0043] The electric actuator 32 can precisely control the movement speed and stroke of the slider 35. For example, uniform movement ensures that the brush roller 31 cleans evenly, avoiding the force deviation of manual cleaning, such as excessive force in some areas damaging the inclined plate 2, or insufficient force leaving residual sludge, ensuring stable cleaning effect. Moreover, the electric actuator 32 can be driven without interrupting the operation of the sedimentation tank 1, and can be started during water inlet gaps or low loads, solving the problem of traditional manual cleaning requiring machine shutdown, reducing the impact on the continuity of water supply to the water plant, and reducing operational losses caused by downtime.

[0044] An inlet 12 is provided on one side of the sedimentation tank 1. The inlet 12 is L-shaped and communicates with the inner cavity of the sedimentation tank 1. An outlet 11 is provided on the upper side of the sedimentation tank 1 away from the inlet 12.

[0045] The L-shaped inlet 12 can buffer the impact of incoming water, thereby preventing the impact force from directly hitting the inclined plate 2, allowing the water flow to spread smoothly along the pool wall, reducing the amount of sludge re-attached to the surface of the inclined plate 2 due to water flow disturbance, and indirectly reducing the burden on the cleaning mechanism. In addition, the outlet 11 is located on the upper side of the end away from the inlet 12, which can guide the clear water layer to overflow smoothly. Combined with the sedimentation effect of the inclined plate 2, the sludge can be quickly settled to the bottom of the pool, reducing the amount of sludge attached to the surface of the inclined plate 2 and extending the cleaning cycle.

[0046] The bristles of the brush roller 31 are made of nylon material. Nylon bristles have the characteristics of acid and alkali corrosion resistance, high strength and smooth surface, which can effectively reduce sludge adhesion and improve cleaning efficiency.

[0047] The nylon bristles are resistant to acid and alkali corrosion and microbial corrosion, extending their service life. Their smooth surface reduces sludge adhesion, preventing sludge from being transferred to the clean area during cleaning. This ensures that the inclined plate 2 is free of residual impurities after cleaning, maintaining sedimentation efficiency. At the same time, their high strength allows them to withstand long-term friction without shedding or deforming, preventing scratches on the inclined plate 2 due to brush damage, extending the service life of the inclined plate 2, and indirectly reducing the overall maintenance cost of the equipment.

[0048] Example 2:

[0049] like Figure 3-4 As shown, a tooth 34 is fixedly connected to the inner wall of one of the connecting frames 3 in each group, and a gear 36 is fixedly connected to the outer side of the connecting shaft 33 on one side of the tooth 34, and the gear 36 meshes with the tooth 34.

[0050] When the brush roller 31 moves, the gear 36 meshes with the teeth 34, driving the connecting shaft 33 to rotate. This allows the brush roller 31 to simultaneously achieve a compound motion of translation along the end face of the inclined plate 2 and its own rotation. As a result, the rotating bristles can penetrate deep into the fine textures on the surface of the inclined plate 2, improving the removal rate of stubborn sludge compared to simple translation cleaning, avoiding secondary manual cleaning. Furthermore, the kinetic energy of the translation of the slider 35 is converted into the mechanical energy of the rotation of the brush roller 31, eliminating the need for an additional rotation drive device (such as a motor), thus maintaining the advantage of no additional cost. Moreover, the meshing transmission of the gear 36 and the teeth 34 ensures that the rotation speed and translation speed of the brush roller 31 are kept in a constant ratio, ensuring that the force exerted by the bristles on the end face of the inclined plate 2 is uniform, maintaining consistent cleaning results, and reducing fluctuations in the sedimentation efficiency of the inclined plate 2 caused by uneven cleaning.

[0051] The connecting frame 3, teeth 34, and gear 36 are all integrally molded from polytetrafluoroethylene.

[0052] The PTFE (polytetrafluoroethylene) material, resistant to acid and alkali corrosion and microbial adhesion within the sedimentation tank 1, extends the service life compared to traditional metal or ordinary plastic parts. This reduces cleaning mechanism jamming caused by component corrosion. Furthermore, the smooth surface of the material reduces sludge adhesion to the connecting frame 3, teeth 34, and gears 36, minimizing the impact of post-cleaning residue on transmission accuracy and reducing additional cleaning work caused by adhesion.

[0053] Example 3:

[0054] like Figure 1-2 As shown, each of the connecting frames 3 is fixedly connected to a water guide pipe 4, and the end of the water guide pipe 4 near the brush roller 31 is fixedly connected to a plurality of water spray heads 41, and the plurality of water spray heads 41 are all corresponding to the brush roller 31.

[0055] The water supply pipe 4 connects to an external water source, allowing the water spray head 41 to spray water onto the brush roller 31 and the end face of the inclined plate 2. This softens the hardened sludge beforehand, making it easier for the brush roller 31 to peel off the sludge. The water flow also washes away the sludge adhering to the surface of the brush roller 31, preventing the sludge from drying on the brush, maintaining the cleaning ability of the bristles, and extending the service life of the brush. Furthermore, the water spray can cover the edges of the inclined plate 2 that are difficult for the brush roller 31 to reach. Combined with the mechanical cleaning of the brush, this forms a composite cleaning of water rinsing and brushing, reducing cleaning dead corners, ensuring that the surface of the inclined plate 2 is completely clean, and reducing the frequency of manual cleaning.

[0056] Example 4:

[0057] like Figure 1-2 As shown, a plurality of V-shaped sludge collection covers 52 are fixedly connected to the bottom of the inner cavity of the sedimentation tank 1, and a sludge discharge pipe 5 is connected between the bottoms of the plurality of sludge collection covers 52. A sludge pump 51 is installed at one end of the sludge discharge pipe 5.

[0058] The sludge falling from the inclined plate 2 through the V-shaped sludge collection hood 52 is guided to the bottom, reducing the residual area of ​​sludge at the bottom of the tank. Then, the sludge pump 51 is started to pump the sludge out of the sludge collection hood 52 through the sludge discharge pipe 5. It can be operated synchronously with the cleaning mechanism to prevent the sludge from being resuspended and re-attached to the surface of the inclined plate 2, thus maintaining the long-term cleanliness of the sedimentation tank 1.

[0059] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
