Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sludge discharging device for sewage treatment. Background Technique

[0002] In the process of sewage treatment, sedimentation is a key link, and effectively discharging the sludge in the sedimentation tank is an important step to ensure the sewage treatment effect. Traditional sewage treatment sludge discharging devices often have some problems. For example, the sludge discharging efficiency is low, and it is easy to have the situation of sludge accumulation and blockage in the pipeline, which affects the normal progress of sewage treatment. At the same time, some sludge discharging devices may have water leakage problems during operation, which not only wastes water resources but also may pollute the surrounding environment. In addition, the traditional sludge discharging device is not thorough enough in cleaning the sedimentation tank after sludge discharging, and the remaining soil will affect the effective volume and hydraulic conditions of the sedimentation tank, reducing the sewage treatment efficiency. To solve these problems, a new type of sludge discharging device for sewage treatment has emerged. This device improves the sludge discharging efficiency through optimized structural design, avoids sludge accumulation and water leakage, and realizes the recycling of water resources at the same time, which is of great significance for improving the sewage treatment effect, reducing water resource consumption and protecting the environment.

[0024] In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Embodiment 1

[0026] Please refer to the attached Figure 1 - attached Figure 6 , mainly composed of a sedimentation tank 1, a first motor 4 and a flushing assembly 9. Above the sedimentation tank 1, a load-bearing frame 2 is firmly fixed. Above the load-bearing frame 2, a support 3 is steadily fixed. On this fixed support 3, a first motor 4 is installed. On the rotating shaft of the first motor 4, a rotating rod 5 is assembled. At the bottom of the rotating rod 5, a scraper 6 is firmly fixed. At the edge position of the sedimentation tank 1, a water inlet 10 and a water outlet 11 are respectively opened, and valves 12 are installed in these two ports to effectively control the water flow.

[0027] Further below the sedimentation tank 1, a support plate 7 is installed, and below the support plate 7, support feet 8 are installed to provide stable support for the entire device. Above the interior of the sedimentation tank 1, a stabilizing column 18 is installed. An installation frame 17 is installed on the stabilizing column 18. Below the installation frame 17, a hydraulic device 22 is installed. This hydraulic device 22 is connected to a sealing disc 19. Below the sedimentation tank 1, a sludge discharge pipe 20 is installed. Inside the inlet of the sludge discharge pipe 20, a first rotating shaft 23 is installed. Four blades 24 are evenly installed on the first rotating shaft 23. One side of the first rotating shaft 23 is connected to a second motor 13. The second motor 13 is installed on the sedimentation tank 1 through a fixing frame 16. At the corner below the sludge discharge pipe 20, a second rotating shaft 25 is installed. A spiral blade 26 is installed on the second rotating shaft 25. One side of the second rotating shaft 25 is connected to an external transmission wheel 14, and the other side is fixed to a suspension rod 27. The transmission wheel 14 is linked to the first rotating shaft 23 above by a belt 15. At the outlet of the sludge discharge pipe 20, a protective cover plate 21 is installed.

[0028] In summary, a water storage tank 91 is installed on the support plate 7. A water pump 92 is installed inside the water storage tank 91. The water pump 92 is connected to a delivery pipe 93. The delivery pipe 93 communicates with an annular pipe 95. High-pressure nozzles 96 are evenly installed around the annular pipe 95. An inlet pipe 94 is installed on the sedimentation tank 1, and the other end of this pipe extends into the water storage tank 91.

[0029] Working principle:

[0030] (1) Sedimentation process

[0031] Sewage flows into the sedimentation tank 1 through the water inlet 10. In the sedimentation tank 1, due to the action of gravity, the solid particles in the water gradually settle to the bottom of the tank. At this time, the valves 12 at the water inlet 10 and the water outlet 11 can be adjusted as needed to control the water flow rate and flow volume to ensure the sedimentation effect.

[0032] (2) Mud scraping process

[0033] The first motor 4 is started, driving the rotating rod 5 to rotate, so that the bottom scraper 6 rotates inside the sedimentation tank 1. The function of the scraper 6 is to scrape the sludge deposited at the bottom of the tank towards the sludge discharge port for subsequent sludge discharge operations.

[0034] (3) Sludge discharge process

[0035] Sludge suction: When sludge discharge is required, the hydraulic device 22 drives the sealing disk 19 to rise, opening the inlet of the sludge discharge pipe 20. At the same time, the second motor 13 starts, driving the first rotating shaft 23 to rotate. The four blades 24 on the first rotating shaft 23 rotate accordingly, and the rotation of the blades 24 generates suction, quickly sucking the sludge near the sludge discharge port at the bottom of the sedimentation tank 1 into the sludge discharge pipe 20.

[0036] Corner transportation: After the sludge enters the sludge discharge pipe 20 and reaches the lower corner, at this time, the operation of the second motor 13 drives the driving wheel 14 to rotate through the belt 15, and then drives the second rotating shaft 25 to operate. The spiral blade 26 on the second rotating shaft 25 pushes the sludge forward, ensuring that the sludge smoothly passes through the corner and continues to move towards the outlet of the sludge discharge pipe 20.

[0037] Protection and discharge: At the outlet of the sludge discharge pipe 20, a protective cover plate 21 is installed to prevent sludge splashing or causing harm to surrounding personnel during the sludge discharge process. The sludge finally discharges from the outlet of the sludge discharge pipe 20, completing the sludge discharge operation.

[0038] (4) Flushing process

[0039] Water storage: During the sedimentation process, a part of the settled water can be introduced into the water storage tank 91 for storage by turning the valve 12 of the water inlet pipe 94.

[0040] Flushing start: When the sedimentation tank 1 needs to be flushed, the water pump 92 starts, and the water in the water storage tank 91 is transported through the delivery pipe 93 to the annular pipe 95.

[0041] High-pressure flushing: The high-pressure nozzles 96 evenly installed around the annular pipe 95 spray water into the sedimentation tank 1 in the form of high-pressure jets. These high-pressure nozzles 96 can cover all corners of the sedimentation tank 1, flushing the soil that the scraper 6 fails to scrape clean, ensuring the cleanliness of the sedimentation tank 1. The flushing water can enter the sewage treatment system again through the water inlet 10 or other channels for cyclic treatment.

[0042] Embodiment 2

[0043] Please refer to the appendix Figure 4 - Appendix Figure 6, the hydraulic device 22 installed on the mounting frame 17 exerts a driving force to push the sealing disc 19 to move, so that the mud discharge port can be tightly sealed. In this way, the occurrence of water leakage can be effectively prevented, ensuring the sealing and stability of the entire mud discharge system. When the second motor 13 starts to operate, it drives the first rotating shaft 23 to operate efficiently with stable and continuous power. As the first rotating shaft 23 rotates, the blades 24 installed on it also start to rotate rapidly. These blades 24 can generate a strong suction force during rotation, so that the sediment at the hole can be quickly sucked into the pipeline at a relatively fast speed. This process is efficient and accurate, greatly improving the efficiency of sediment suction. At the corner of the mud discharge pipe 20, after the first motor 4 operates to drive the first rotating shaft 23, it is connected to the lower transmission wheel 14 through the durable belt 15, and the power of the first motor 4 can be accurately transmitted to the transmission wheel 14. After the transmission wheel 14 obtains the power, it then drives the second rotating shaft 25 to operate. When the sediment falls from the upper pipeline into the lower pipeline, the spiral blades 26 on the second rotating shaft 25 start to play a key role. These spiral blades 26 can strongly push the sediment out. This design cleverly avoids the situation of sediment accumulation at the corner, ensuring that the sediment can always be discharged smoothly from the pipeline. Through such coordinated operation, the mud discharge efficiency is higher, providing a strong guarantee for the stable operation of the entire sewage treatment system. At the end of the mud discharge pipe 20, a protective cover plate 21 is installed. This protective cover plate 21 can play an important protective role during the operation of the machine. It can effectively prevent sediment from splashing, avoiding adverse effects on the surrounding environment and operators. At the same time, the protective cover plate 21 can also prevent external sundries from entering the mud discharge pipe 20 to a certain extent, ensuring the normal operation of the mud discharge system.

[0044] Working principle: The hydraulic device 22 installed on the mounting bracket 17 is activated, pushing the sealing disc 19 to move to the mud discharge port, tightly sealing the mud discharge port. This can effectively prevent water from leaking through the mud discharge port during the sedimentation process or other situations, ensuring the sealing and stability of the entire system, and creating good conditions for subsequent mud discharge operations. When mud discharge operation is required, the second motor 13 starts to operate. The second motor 13 drives the first rotating shaft 23 to rotate at high speed with continuous power. As the first rotating shaft 23 rotates, the blades 24 installed on it also start to rotate rapidly. These blades 24 generate a strong suction force during rotation, causing the sediment located at the hole to be quickly sucked into the pipeline interior. Due to the design of the blades 24 being able to efficiently generate suction force, the sediment can enter the pipeline at a relatively fast speed, thereby improving the initial efficiency of mud discharge. At the corner of the mud discharge pipe 20, the first motor 4 operates to drive the first rotating shaft 23 to rotate. The first rotating shaft 23 is connected to the transmission wheel 14 below through a sturdy and durable belt 15. During the transmission process of the belt 15, the power of the first motor 4 is accurately transmitted to the transmission wheel 14. After the transmission wheel 14 obtains power, it drives the second rotating shaft 25 to operate. When the sediment falls from the upper pipeline into the lower pipeline, the spiral blades 26 on the second rotating shaft 25 start to play a key role. The spiral blades 26 are designed in a spiral shape and can powerfully push the sediment forward during rotation. This design cleverly avoids the accumulation of sediment at the corner, ensuring that the sediment can always pass through the corner smoothly and continue to move towards the outlet direction of the mud discharge pipe 20. Through the coordinated operation of the first motor 4, the belt 15, the transmission wheel 14, and the second rotating shaft 25, the efficient transportation of sediment in the mud discharge pipe 20 is achieved. A protective cover plate 21 is installed at the end of the mud discharge pipe 20. When the machine is working, the protective cover plate 21 can play an important protective role. On the one hand, it can prevent the sediment from splashing during discharge, avoiding adverse effects on the surrounding environment and operators. On the other hand, the protective cover plate 21 can also prevent external debris from entering the mud discharge pipe 20 to a certain extent, ensuring the normal operation of the mud discharge system and guaranteeing the safety and reliability of the entire device.

[0045] Embodiment 3

[0046] Please refer to the appendix Figure 1 - appendix Figure 3, by turning the valve 12 on the water inlet pipe 94, a part of the sedimented water can flow smoothly into the water storage tank 91 for storage. When sludge discharge operation is required, the powerful water pump 92 is started. At this time, the water pump 92 can transport the water stored in the water storage tank 91 to the annular pipe 95 in a stable and efficient manner. Along the circumference of the annular pipe 95, numerous high-pressure nozzles 96 are evenly distributed. These high-pressure nozzles 96 have a powerful spraying ability and can strongly wash the sedimentation tank 1. The high-speed water flow ejected from the high-pressure nozzles 96 can wash the soil that the scraper 6 fails to completely scrape clean during operation. This method realizes the efficient recycling of water resources. On the one hand, it greatly reduces the dependence on fresh water resources. During the entire sewage treatment process, there is no need to continuously introduce a large amount of new water resources, thus significantly reducing the consumption of water resources. On the other hand, this way of recycling water resources also greatly enhances the sewage treatment effect. Timely cleaning of the soil in the sedimentation tank 1 is of crucial significance. It can effectively maintain the effective volume of the sedimentation tank 1, ensuring that the sedimentation tank 1 always has enough space for sewage sedimentation treatment work. At the same time, good hydraulic conditions can also be continuously maintained, enabling the sewage to flow smoothly in the sedimentation tank 1 according to the predetermined process, thus ensuring the stable progress of the sewage treatment process.

[0047] Working principle: By turning the valve 12 on the water inlet pipe 94, the water flow can be precisely controlled. When the valve 12 is at a specific angle, a part of the sedimented water will flow from the sedimentation tank 1 into the water storage tank 91 for storage under the action of gravity and water flow pressure. This process utilizes the natural flow characteristics of water and the adjustment function of the valve 12 to achieve the collection and storage of the sedimented water resources. When sludge discharge operation is required, the water pump 92 starts to work. The water pump 92 extracts the water from the water storage tank 91 and transports it to the annular pipe 95 at a certain pressure. The water flows in the annular pipe 95 and reaches the high-pressure nozzles 96 evenly distributed along the circumference of the annular pipe 95, and sprays the water into the sedimentation tank 1 in the form of high-speed jets. These high-speed water flows have a powerful impact force and can wash the soil that the scraper 6 fails to completely scrape clean. The even distribution of the high-pressure nozzles 96 ensures the comprehensiveness of the washing and avoids dead corners. In this way, the recycling of water resources is realized. The sedimented water returns to the sewage treatment system again after the processes of storage, transportation and washing. This not only reduces the dependence on fresh water resources and the consumption of water resources during sewage treatment, but also enhances the sewage treatment effect. Timely cleaning of the soil in the sedimentation tank 1 maintains the effective volume of the sedimentation tank 1, enabling the sedimentation tank 1 to continuously and efficiently carry out sewage sedimentation treatment. At the same time, good hydraulic conditions are maintained to ensure the smooth flow of sewage in the sedimentation tank 1 and guarantee the stable progress of the sewage treatment process.

[0048] Example 4

[0049] Please refer to the attached Figure 1 - attached Figure 6 ,

[0050] Above the sedimentation tank 1, a load-bearing frame 2 is installed. Above the load-bearing frame 2, a structurally stable support 3 is installed. On the support 3, the first motor 4 is firmly fixed by a series of secure screws, ensuring that the first motor 4 does not show the slightest looseness or displacement during operation. Below the first motor 4, a rotating rod 5 is precisely fixed on its rotating shaft. It can rotate stably as the first motor 4 operates and accurately transmit power to the scraper 6 below. The precise connection of the rotating rod 5 ensures that the scraper 6 can work efficiently, improving the working efficiency of the entire system. Below the rotating rod 5, a scraper 6 is installed, which can effectively scrape the sediment at the bottom of the sedimentation tank 1, keeping the sedimentation tank 1 clean and unobstructed. The presence of the scraper 6 greatly improves the sedimentation effect of the sedimentation tank 1 and reduces the impact of sediment on the subsequent treatment process. On one side of the sedimentation tank 1, a water inlet 10 and a water outlet 11 are respectively provided. The water inlet 10 is used to introduce the sewage to be treated into the sedimentation tank 1, while the water outlet 11 is used to discharge the clarified water after sedimentation treatment from the sedimentation tank 1, facilitating the inflow of sewage and the discharge of treated water, helping to maintain the water level balance and water flow stability in the sedimentation tank 1, and further promoting the sedimentation process. The presence of the water inlet 10 and the water outlet 11 improves the treatment efficiency of the entire system, making the sewage treatment process smoother. Below the sedimentation tank 1, a support plate 7 is provided. The support plate 7 has good load-bearing capacity and stability. It can provide additional support for the sedimentation tank 1, ensuring that the sedimentation tank 1 does not sink or tilt during operation. The presence of the support plate 7 enhances the stability of the entire system and extends the service life of the equipment. Below the support plate 7, a set of support feet 8 is installed. The support feet 8 have good stability and seismic resistance. They can firmly support the entire system on the ground, preventing the system from shaking or displacing during operation. The height of the support feet 8 can be adjusted according to actual needs to adapt to different working environments and installation requirements.

[0051] Working principle:

[0052] The load-bearing frame 2 is installed above the sedimentation tank 1 to provide stable support for the bracket 3 above. The load-bearing frame 2 is made of strong material and can bear the weight of the bracket 3 and the first motor 4 installed on the bracket 3 and other equipment. The bracket 3 is installed above the load-bearing frame 2, and the first motor 4 is firmly fixed thereon by screws. This fixing method ensures that the first motor 4 will not shake or shift during operation, thereby ensuring the stable operation of the motor. The support plate 7 is located below the sedimentation tank 1 to provide additional support for the sedimentation tank 1. The support tripod 8 is installed below the support plate 7 to stably support the entire device on the ground. After the machine 4 is started, its operating shaft begins to rotate, and the rotating rod 5 fixed on the rotating shaft rotates accordingly, transmitting the power of the motor to the scraper 6 below. The scraper 6 is installed below the rotating rod 5. As the rotating rod 5 rotates, it scrapes at the bottom of the sedimentation tank 1. The function of the scraper 6 is to scrape the sludge and other sediments settled at the bottom of the tank to a specific discharge position for subsequent treatment. The sewage enters the sedimentation tank 1 through the water inlet 10 on one side of the sedimentation tank 1. In the sedimentation tank 1, due to the effect of gravity, the solid particles in the sewage gradually settle to the bottom of the tank, and the clean water after sedimentation treatment flows out from the water outlet 11 on one side of the sedimentation tank 1.

[0053] Workflow:

[0054] First, sewage flows into the sedimentation tank 1 through the water inlet 10 on the side of the sedimentation tank 1. In the sedimentation tank 1, due to the effect of gravity, the solid particles in the sewage gradually settle to the bottom of the tank. After the sedimentation is completed, a part of the settled water is introduced into the water storage tank 91 for storage by twisting the valve 12 of the water inlet pipe 94. The water outlet 11 is opened to discharge the settled water. The first motor 4 is started to drive the rotating rod 5 to rotate, so that the scraper 6 at the bottom is in a waiting state. The scraper 6 rotates in the sedimentation tank 1 driven by the rotating rod 5 to scrape the sludge settled at the bottom of the tank toward the mud discharge port to prepare for subsequent mud discharge. When mud discharge is required, the hydraulic cylinder 22 on the mounting frame 17 pulls up the sealing disk 19 to open the entrance of the mud discharge pipe 20, and the second motor 13 drives the first motor 4 to start the first motor 4 to start the second ... A rotating shaft 23 rotates, causing the blades 24 on the first rotating shaft 23 to rotate, generating suction to quickly suck the mud at the hole into the mud discharge pipe 20. After the first motor 4 drives the first rotating shaft 23, it is connected to the transmission wheel 14 below through the belt 15, and then drives the second rotating shaft 25 to operate. After the mud falls into the pipe below, the spiral blades 26 on the second rotating shaft 25 push the mud out to avoid mud accumulation at the corners, ensuring that the mud is discharged smoothly from the pipe. After the mud discharge operation is performed, the water pump 92 is started to transport the water in the water tank 91 to the annular pipe 95. The high-pressure nozzles 96 evenly distributed around the annular pipe 95 flush the sedimentation tank to flush the mud that the scraper 6 has not scraped clean. At this point, the entire work process ends.
