Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device. Background Technology

[0002] Currently, commonly used wastewater treatment equipment in the field of wastewater treatment technology meets the needs of some users to a certain extent, and the market response has been positive. However, in practical applications, there are still many shortcomings.

[0003] First, after the equipment has been running for a period of time, sedimentation will occur in the inlet jacket of the flocculation chamber. Impurities and suspended solids in the sewage gradually accumulate in the inlet jacket, which not only affects the stability of the inlet water flow, causing changes in the flow velocity and direction, but also further affects the stability of the suspended layer, reducing the sewage treatment effect.

[0004] Secondly, sludge deposition in the collector within the flocculation chamber is also a significant problem. Sludge buildup hinders normal wastewater discharge, preventing the collector from effectively collecting and discharging sludge, thus affecting the overall operating efficiency of the equipment.

[0005] Currently, to solve the above problems, users usually need to regularly drain and backwash the equipment. However, this operation is quite cumbersome and requires the on-site installation of infrastructure such as raw water collection tanks, product water collection tanks, and sludge collection tanks, which greatly increases the operating cost and floor space required for the equipment.

[0006] In addition, after long-term operation, existing wastewater treatment equipment will have flocs adsorbed on the sight glass, making it difficult for users to clearly observe the flocculation and sedimentation in the flocculation chamber. This makes it difficult for users to adjust equipment operating parameters in a timely manner and discover potential problems. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of existing sewage treatment equipment, such as the tendency for sediment to accumulate in the inlet jacket and collector, requiring regular backwashing, and the tendency for dirt to adhere to the sight glass surface, affecting observation, and to provide a sewage treatment device.

[0008] This utility model is achieved through the following technical solution: a sewage treatment device includes a tank body, an annular overflow trough is provided on the inner top of the tank body, the overflow trough and the tank body are integrally formed, a plurality of overflow ports are provided on the inner side wall of the overflow trough, and a water outlet pipe connected to the overflow trough is provided on the upper part of the tank body; a conical vortex bucket is provided inside the tank body, the bottom of the vortex bucket faces upward, and the diameter of the bottom of the vortex bucket is smaller than the inner diameter of the overflow trough, and the vortex bucket is fixed inside the tank body by a support frame; a water inlet pipe is provided at the lower part of the tank body, one end of the water inlet pipe is located on the outside of the tank body, and the other end of the water inlet pipe passes through the tank body and is connected to the lower part of the vortex bucket, and a sewage discharge pipe is provided at the lower part of the tank body below the vortex bucket.

[0009] During operation, wastewater flows into the tank through the inlet pipe at the bottom and enters the vortex bucket under the pump's thrust. Inside the vortex bucket, the wastewater moves upward at a constant speed in a swirling motion. As the wastewater rises, impurities gradually settle towards the outer wall and bottom of the vortex bucket under the influence of centrifugal force and gravity, achieving initial solid-liquid separation. The treated clean water rises to the overflow tank and flows into the overflow tank through the overflow port on the inner wall, then exits the tank through the outlet pipe connected to the overflow tank. Sludge and other impurities that settle below the vortex bucket are discharged through the drain pipe.

[0010] A further improvement of this utility model is that the overflow channel includes an annular support base plate and a cylindrical water-retaining weir. The support base plate is located at the top of the tank body, and the outer side wall of the support base plate is connected to the inner side wall of the tank body. The inner diameter of the water-retaining weir corresponds to the inner diameter of the support base plate, and the bottom side of the water-retaining weir is connected to the inner circular side of the support base plate. The overflow port is located at the upper edge of the water-retaining weir. The support base plate and the water-retaining weir cooperate with the inner side wall of the tank body to form a complete overflow channel.

[0011] A further improvement of this utility model is that the overflow port is triangular, and several overflow ports are arranged evenly in sequence along the circumference to form a sawtooth structure.

[0012] A further improvement of this utility model is that the support frame includes several connecting rods, which are evenly spaced along the circumference, and one end of the connecting rod is connected to the inner wall of the tank body, while the other end of the connecting rod is connected to the outer wall of the vortex bucket.

[0013] A further improvement of this utility model is that a conical sludge hopper is provided at the bottom of the tank body, and the lower part of the sludge hopper is connected to the sludge pipe.

[0014] A further improvement of this utility model is that a guide plate is provided at the inner bottom of the sewage hopper, the guide plate is arranged at an angle, and the lower end of the guide plate corresponds to the inner bottom side of the sewage pipe.

[0015] A further improvement of this invention is that the top of the tank body and the top of the overflow trough are both open.

[0016] A further improvement of this utility model is that the bottom of the sewage hopper is provided with support legs.

[0017] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0018] 1. This wastewater treatment device uses a cyclone bucket to treat wastewater through swirling, utilizing centrifugal force and gravity to cause impurities to settle. Combined with an annular overflow trough and a specially designed overflow port, it can efficiently achieve solid-liquid separation, steadily improve the quality of produced water, and reduce the impact of impurities on subsequent processes. Simultaneously, the design of the discharge hopper and guide plates ensures that sludge and other impurities are smoothly discharged, preventing them from remaining inside the equipment and affecting the treatment effect.

[0019] 2. The components of this wastewater treatment unit are rationally designed. For example, the support frame stabilizes the vortex bucket, ensuring stable vortex treatment; the inner diameter of the outlet pipe is larger than that of the inlet pipe, ensuring rapid and smooth discharge of clean water, maintaining a stable water level in the tank, avoiding water flow turbulence, improving treatment efficiency, and reducing equipment failures caused by water flow problems. Furthermore, the open top design allows operators to easily observe the equipment's operating status and adjust operating parameters in a timely manner, further ensuring stable operation.

[0020] 3. The overall structural design of this wastewater treatment device allows it to operate well in various scenarios. The support legs at the bottom of the discharge hopper enhance the stability of the equipment in special installation environments, improving its applicability. Furthermore, the optimized structure of this wastewater treatment device reduces energy consumption, minimizes equipment failures and maintenance costs, and improves economic efficiency.

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] Please refer to the attached document. Figure 1 and Figure 2 The following is a description of a specific embodiment: The wastewater treatment device of this utility model includes a tank body 1. An annular overflow trough 2 is provided at the top inner part of the tank body 1. The overflow trough 2 and the tank body 1 are integrally formed. Several overflow ports 201 are provided on the inner sidewall of the overflow trough 2. A water outlet pipe 3 connected to the overflow trough 2 is provided at the upper part of the tank body 1. A conical vortex bucket 4 is provided inside the tank body 1. The bottom of the vortex bucket 4 faces upwards, and the diameter of the bottom is smaller than the inner diameter of the overflow trough 2. The vortex bucket 4 is fixed inside the tank body 1 by a support frame 5. A water inlet pipe 6 is provided at the lower part of the tank body 1. One end of the water inlet pipe 6 is located outside the tank body 1, and the other end of the water inlet pipe 6 passes through the tank body 1 and connects to the lower part of the vortex bucket 4. A sewage discharge pipe 7 located below the vortex bucket 4 is provided at the lower part of the tank body 1.

[0030] In operation, wastewater flows into the tank body 1 through the inlet pipe 6 at the bottom and enters the vortex bucket 4 with the help of a pump. Inside the vortex bucket 4, the wastewater moves upward at a constant speed in a swirling motion. As the wastewater rises, impurities gradually settle towards the outer wall and bottom of the vortex bucket 4 under the influence of centrifugal force and gravity, achieving initial solid-liquid separation. The treated clean water rises to the overflow tank 2 and flows into the overflow tank 2 through the overflow port 201 on the inner wall of the overflow tank 2. It then exits the tank body 1 through the outlet pipe 3, which is connected to the overflow tank 2. Sludge and other impurities that settle below the vortex bucket 4 are discharged through the drain pipe 7.

[0031] The aforementioned structural design utilizes swirling motion to enhance the separation of impurities from clean water in wastewater, thereby improving wastewater treatment efficiency. Simultaneously, the overflow trough 2 and outlet pipe 3 ensure a stable discharge of treated clean water, enhancing the stability of equipment operation. Compared to existing wastewater treatment equipment, this design avoids the problem of influent layer sedimentation affecting water flow stability and reduces interference with the suspended layer, thus improving the quality of the produced water.

[0032] For details, please refer to the appendix. Figure 5 The overflow trough 2 includes an annular support base plate 202 and a cylindrical water-retaining weir 203. The support base plate 202 is located at the top inside the tank body 1. The outer side wall of the support base plate 202 is connected to the inner side wall of the tank body 1. The inner diameter of the water-retaining weir 203 corresponds to the inner diameter of the support base plate 202. The bottom side of the water-retaining weir 203 is connected to the inner circular side of the support base plate 202. The overflow port 201 is located at the upper edge of the water-retaining weir 203. The support base plate 202 and the water-retaining weir 203 cooperate with the inner side wall of the tank body 1 to form a complete overflow trough 2.

[0033] The overflow trough 2, consisting of an annular support base plate 202 and an annular weir 203, forms a complete overflow space in conjunction with the inner wall of the tank body 1. When the treated clean water rises to the overflow trough 2, the weir 203 acts as a barrier, ensuring that the clean water can only flow into the overflow trough 2 from the overflow port 201 set on the weir 203, and then be discharged through the outlet pipe 3.

[0034] Through the specific structural design of the overflow tank 2, this wastewater treatment device ensures a more standardized and orderly overflow process for clean water, preventing disorderly flow of clean water within the tank and further guaranteeing the stability and quality of the effluent. Unlike the situation where sludge deposition in the flocculation chamber collector affects wastewater discharge, this structure effectively avoids such problems and significantly improves the overall operating efficiency of the equipment.

[0035] For details, please refer to the appendix. Figure 1 and 3 The bottom of the tank body 1 is provided with a conical sewage hopper 8, and the lower part of the sewage hopper 8 is connected to the sewage pipe 7.

[0036] The sludge and other impurities that settle below the vortex bucket 4 are collected along the slope of the sludge discharge bucket 8 by gravity and discharged into the sludge discharge pipe 7, and then discharged out of the tank through the sludge discharge pipe 7.

[0037] The specific structural design of the above-mentioned sewage discharge hopper 8 utilizes the principle of gravity, which allows sludge and other impurities to be collected and discharged more smoothly, enhancing the sewage discharge capacity, reducing sludge deposition at the bottom of the tank, avoiding the problem of sludge accumulation affecting the operation of this sewage treatment device, and further improving the operating efficiency and stability of the equipment.

[0038] For details, please refer to the appendix. Figure 1 , 2 Both the top of the tank body 1 and the top of the overflow trough 2 are open.

[0039] This wastewater treatment device, through its open structure, allows operators to directly observe the wastewater treatment process inside the tank, such as the swirling state of the wastewater in the vortex bucket 4 and the overflow of clean water.

[0040] This structural design solves the problem of obstructed observation caused by dirt adhering to the sight glass surface in existing sewage treatment equipment. It allows operators to promptly detect abnormalities in equipment operation, facilitate timely adjustment of equipment operating parameters, ensure normal equipment operation, and improve the maintainability and ease of use of the equipment.

[0041] Specifically, the inner diameter of the outlet pipe 3 is larger than that of the inlet pipe 6. Because the outlet pipe 3 has a larger inner diameter than the inlet pipe 6, according to fluid mechanics principles, under the same flow rate, a larger pipe diameter results in lower resistance to fluid flow. Therefore, clean water can flow more smoothly within the outlet pipe 3, without experiencing significant resistance due to a smaller pipe diameter, ensuring that clean water can be discharged from the device quickly and stably from the outlet pipe 3.

[0042] For details, please refer to the appendix. Figure 1 and 3 The bottom of the sewage hopper 8 is equipped with support legs 10. Through the specific structural design of the support legs 10, the sewage treatment device ensures the stability of the equipment. Especially in some special installation scenarios, such as when it is placed under water-using equipment and in environments with large height differences, it can ensure that the equipment is placed stably, avoiding the impact of equipment shaking on the sewage treatment effect and normal operation of the equipment, thus improving the applicability and safety of the equipment.

[0043] In one embodiment, refer to the appendix Figure 5 The overflow port 201 is triangular, and several overflow ports 201 are arranged evenly in sequence along the circumference to form a sawtooth structure.

[0044] Through the specific structural design of the overflow outlet 201, this wastewater treatment device allows clean water to flow into the overflow tank 2 through these specially shaped and arranged overflow outlets 201 when it rises to the overflow tank 2. Due to the special shape and distribution of the overflow outlets 201, the clean water can enter the overflow tank more evenly, avoiding excessive or insufficient local water flow.

[0045] Compared to traditional overflow outlet shapes, the triangular and serrated overflow outlet 201 design optimizes the water flow into the overflow tank 2, ensuring uniform water flow within the tank and contributing to improved stability of the treated water quality. Simultaneously, the uniform water flow distribution also helps reduce turbulence within the equipment, further enhancing its operational stability and reliability.

[0046] In one embodiment, the support frame 5 includes a plurality of connecting rods 501, which are evenly spaced circumferentially, with one end of each connecting rod 501 connected to the inner wall of the tank body 1 and the other end of each connecting rod 501 connected to the outer wall of the vortex bucket 4.

[0047] Through the specific structural design of the support frame 5, the vortex bucket 4 is securely fixed inside the tank body 1. When sewage enters the vortex bucket 4 for vortex treatment, the support frame 5 ensures that the vortex bucket 4 remains stable under the impact of the sewage, maintaining the normal operation of the vortex motion.

[0048] The support frame 5 has a simple and stable structural design, effectively ensuring the stability of the vortex bucket 4. This allows the vortex treatment process of wastewater within the vortex bucket 4 to proceed undisturbed, improving the efficiency and sustainability of wastewater treatment. Simultaneously, it reduces fluctuations in wastewater treatment performance caused by unstable equipment components, further enhancing the equipment's operational efficiency.

[0049] In one embodiment, refer to the appendix Figure 3 A guide plate 9 is provided at the bottom of the sewage hopper 8. The guide plate 9 is arranged at an angle, and the lower end of the guide plate 9 corresponds to the bottom side of the sewage pipe 7.

[0050] When sludge and other impurities accumulate at the bottom of the sludge hopper 8, the guide plate 9 guides the impurities to flow along the inclined surface to the sludge pipe 7, ensuring that the impurities can enter the sludge pipe 7 and be discharged more efficiently.

[0051] This wastewater treatment device further optimizes the sewage discharge process through the specific structural design of the guide plate 9, reduces the residue of impurities at the bottom of the sewage discharge hopper 8, improves the thoroughness of sewage discharge, effectively avoids the problem of sludge deposition affecting normal sewage discharge, and enhances the sewage discharge performance and overall operating effect of the equipment.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
