Description

Technical Field

[0001] This utility model relates to the field of inclined tube discharge technology, specifically an inclined tube discharge device for sewage treatment sedimentation tanks. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Inclined tubes are water treatment devices made of materials such as polypropylene, polyvinyl chloride, and fiberglass. They mainly achieve sedimentation and sand removal functions through inclined or straight tube packing. Their specifications cover a variety of pipe diameters and are used in scenarios such as sand removal at the inlet of water supply and drainage projects, sedimentation of industrial and domestic sewage, oil separation treatment, and tailings concentration.

[0003] For example, patent document CN 213077596 U discloses a sludge discharge device for inclined tube sedimentation tanks, including a perforated sludge discharge pipe connected to a branch sludge discharge pipe. The branch sludge discharge pipe is equipped with a pneumatic / electric sludge discharge valve and is connected to a main sludge discharge pipe. The device also includes a suspended particle detector, the detection end of which is located inside the sedimentation tank. A liquid concentration detector is installed on the main sludge discharge pipe. The pneumatic / electric sludge discharge valve, suspended particle detector, and liquid concentration detector are all connected to a control system. This sludge discharge device can automatically discharge sludge based on the sludge concentration in the sludge hopper below the inclined tube sedimentation tank, extending the sludge discharge cycle, preventing sludge accumulation, and reducing production losses and the corresponding manpower and material resources required for sludge removal. It can also automatically stop sludge discharge based on the sludge concentration, improving water reuse rate, increasing water supply capacity, and reducing water and energy consumption.

[0004] However, in actual use, due to its own structural limitations, this structure can only be used for fixed installation of inclined tube structures in sewage treatment sedimentation tanks. It is not possible to perform cleaning and maintenance operations on individual inclined tube discharge structures at any time. At the same time, the equipment cannot perform efficient inlet and outlet operations of inclined tubes in sewage treatment sedimentation tanks, which cannot meet the daily use needs. Therefore, it is urgent to design an inclined tube discharge device for sewage treatment sedimentation tanks to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a wastewater treatment sedimentation tank inclined tube discharge device to solve the problem mentioned in the background art. Due to the limitations of its own structure, the existing structure can only be used for fixed installation of the inclined tube structure in the wastewater treatment sedimentation tank. It is not possible to clean and maintain the individual inclined tube discharge structure at any time. At the same time, the equipment cannot perform efficient inlet and outlet operations of the inclined tube in the wastewater treatment sedimentation tank, and cannot meet the daily use needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewage treatment sedimentation tank inclined tube discharge device, including a separation frame, a sealed inner liner provided on the inner wall of the separation frame, a pumping component movably arranged inside the separation frame through the sealed inner liner, and a sedimentation component provided at the bottom end of the separation frame; The pull-out assembly includes a separation seat, which is movably connected inside the separation frame, and a barrier seat is fixedly connected to one end of the separation seat; The sedimentation assembly includes a conical seat, the bottom end of the separation frame is fixedly connected to the conical seat, and the bottom end of the conical seat is fixedly connected to a drain channel.

[0007] Preferably, one end of the sewage channel is provided with a sewage outlet, and the surface of the sewage channel is uniformly provided with sewage inlets.

[0008] Preferably, the conical seat has a conical groove inside, and the inner walls of the conical groove are provided with drainage grooves on both sides.

[0009] Preferably, sealing rings are provided at both ends and between the separating seat and the barrier seat, and sealing baffles are provided at the upper and lower ends of the barrier seat.

[0010] Preferably, the separation seat has a sedimentation seat disposed inside at an offset, and the surface of the sedimentation seat is uniformly provided with sedimentation inclined tubes.

[0011] Preferably, a top cover is fixedly connected to the top of the separation frame, and a drain pipe is fixedly connected to the top of the top cover.

[0012] Preferably, the separation frame is adapted to the separation seat and the barrier seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This inclined tube discharge device for wastewater treatment sedimentation tanks, through its separation frame, sealed inner liner, separation seat, barrier seat, sealing ring, sealing baffle, sedimentation seat, and sedimentation inclined tube, allows for more suitable inclined tube discharge maintenance operations for wastewater treatment sedimentation tanks. In actual use, operators first seal multiple sets of separation seats inside the sealed inner liner of the separation frame. Wastewater flows from top to bottom through the separation frame, working in conjunction with the sedimentation seat and sedimentation inclined tube inside to achieve rapid sludge sedimentation and separation. When one set of separation seats has been used for a period of time, it can be pulled out, causing the barrier seat at one end to seal against the upper and lower ends of the separation frame via the sealing baffles. This allows for quick individual cleaning and maintenance of the separation seat. When switching between separation seats and barrier seats, the sealing rings at both ends and the center can be sealed against the inner wall of the separation frame, ensuring a tight connection and demonstrating the comprehensiveness of the equipment design.

[0014] This inclined tube discharge device for wastewater treatment sedimentation tanks, through its set of separation frames, separation seats, conical seats, discharge channels, discharge outlets, inlets, conical grooves, discharge troughs, top covers, and top drain pipes, further improves the overall efficiency of the equipment. During daily use, operators can install the conical seats and discharge channels at the bottom of all separation frames. Sludge settled inside the separation frames via the separation seats can quickly gather and flow downwards along the discharge channels on both sides of the conical grooves inside the conical seats, ultimately converging at the inlet of the discharge channel and being rapidly discharged from the discharge outlet at one end. Simultaneously, clean water can be quickly discharged from the top through the top cover and top drain pipe at the top of the separation frames, greatly improving the overall discharge efficiency of the inclined tube discharge device for wastewater treatment sedimentation tanks and demonstrating the comprehensiveness of the equipment design.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 One embodiment provided by this utility model: A wastewater treatment sedimentation tank inclined tube discharge device includes a separation frame 1, with a sealed inner liner 2 on the inner wall of the separation frame 1. A pumping component is movably installed inside the separation frame 1 via the sealed inner liner 2. A sedimentation component is installed at the bottom of the separation frame 1. The pumping component includes a separation seat 3, which is movably connected inside the separation frame 1. A barrier seat 4 is fixedly connected to one end of the separation seat 3. A sedimentation seat 13 is staggered inside the separation seat 3. Sedimentation inclined tubes 14 are evenly distributed on the surface of the sedimentation seat 13. A top cover 15 is fixedly connected to the top of the separation frame 1, and a discharge top pipe 16 is fixedly connected to the top of the top cover 15. The separation frame 1 is compatible with the separation seat 3 and the barrier seat 4. After a set of separation seats 3 has been used for a period of time, it can be pulled out so that the barrier seat 4 at one end can be sealed at the upper and lower ends of the separation frame 1 by the sealing baffles 12 at both ends. Then, the separation seat 3 can be cleaned and maintained individually. The conical seat 5 and the sewage channel 6 are installed at the bottom of all separation frames 1. The sludge that has settled inside the separation frame 1 through the separation seat 3 can quickly gather and flow downward along the sewage channels 10 on both sides of the inner wall of the conical groove 9 inside the conical seat 5, and finally collect from the sewage inlet 8 of the sewage channel 6.

[0019] The sedimentation assembly includes a conical seat 5, a conical seat 5 fixedly connected to the bottom end of the separation frame 1, a sewage channel 6 fixedly connected to the bottom end of the conical seat 5, a sewage outlet 7 provided at one end of the sewage channel 6, sewage inlets 8 evenly opened on the surface of the sewage channel 6, a conical groove 9 opened inside the conical seat 5, sewage outlets 10 provided on both sides of the inner wall of the conical groove 9, a sealing ring 11 provided at both ends and between the separation seat 3 and the barrier seat 4, and a sealing baffle 12 provided at the upper and lower ends of the barrier seat 4.

[0020] Working principle: During use, the operator first seals and installs multiple sets of separation seats 3 inside the sealed inner liner 2 of the separation frame 1. Normally, wastewater flows from top to bottom inside the separation frame 1, which, in conjunction with the sedimentation seat 13 and sedimentation inclined tube 14 inside the separation seat 3, allows for rapid sludge sedimentation and separation. After one set of separation seats 3 has been used for a period of time, it can be pulled out, causing the barrier seat 4 at one end to seal against the upper and lower ends of the separation frame 1 via the sealing baffles 12 at both ends. Then, the separation seat 3 can be quickly cleaned and maintained individually. When switching between the separation seat 3 and the barrier seat 4, the sealing rings 11 at both ends and the center can contact the inner wall of the separation frame 1. The sealing and docking operation ensures the connection is airtight. During daily use, the staff can combine the conical seat 5 and the sewage discharge channel 6 at the bottom of all the separation frames 1. The sludge that has settled inside the separation frame 1 after passing through the separation seat 3 can quickly gather and flow downwards along the sewage discharge channels 10 on both sides of the inner wall of the conical groove 9 inside the conical seat 5. Finally, it will be collected at the sewage inlet 8 of the sewage discharge channel 6 and quickly discharged from the sewage outlet 7 at one end. At the same time, clean water can be quickly discharged from the top through the top cover 15 and the top drain pipe 16 at the top of the separation frame 1, which greatly improves the overall sewage treatment sedimentation tank inclined tube discharge efficiency of the equipment. The above is the complete working principle of this utility model.
