Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a water inlet tank for increasing the suction head of a sewage treatment device. Background Technology

[0002] The AO+MBR membrane process is a highly efficient wastewater treatment process that combines AO (anaerobic-aerobic) biological treatment with MBR (membrane bioreactor) membrane separation technology. Because the installation distance between the integrated wastewater treatment equipment tank and the equipment room exceeds the suction range of the self-priming pump itself, a priming tank needs to be installed in the equipment room at the inlet position of the self-priming pump. This priming tank stores a certain amount of water, with the water level higher than the inlet of the self-priming pump. When the self-priming pump starts, the water in the priming tank can quickly enter the pump under gravity, helping the pump to expel air more quickly, creating an effective vacuum, enabling the self-priming pump to draw water normally, and ensuring the smooth operation of the entire wastewater treatment system's influent process.

[0003] Traditional equipment does not fully consider the spatial layout differences of different wastewater treatment sites. In some underground wastewater treatment sites with limited space, or industrial plants with special requirements for equipment layout, existing water tanks and related auxiliary equipment are often difficult to find suitable installation locations due to their single installation method. At the same time, traditional equipment often lacks a complete flow and water quality monitoring system, and cannot accurately grasp the flow rate of wastewater entering and leaving the water tank as well as the specific indicators of the output water quality.

[0004] Therefore, there is an urgent need to design a wastewater treatment device with an increased suction head, which can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a water inlet tank for increasing the suction head of a sewage treatment device, so as to solve the problem that traditional devices do not fully consider the spatial layout differences of different sewage treatment sites. In some underground sewage treatment sites with limited space, or industrial plants with special requirements for equipment layout, existing water inlet tanks and related auxiliary equipment are often difficult to find suitable installation locations due to the single installation method. At the same time, traditional devices often lack a complete flow and water quality monitoring system, and cannot accurately grasp the sewage flow rate entering and leaving the water inlet tank and the specific indicators of the output water quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A priming tank for increasing the suction head of a wastewater treatment device includes a priming tank, an inlet located near the top of the priming tank, an outlet located at the bottom of the priming tank, an installation assembly on the priming tank, a float sensor located inside the priming tank, an exhaust valve located at the top of the priming tank, and a cover plate located at the top of the priming tank connected by a flange. The inlet is connected to a filter assembly, the priming tank is connected to a membrane assembly, and the priming tank is connected to a self-priming pump.

[0008] Furthermore, the installation assembly includes an L-shaped fixing plate disposed at the bottom of the water tank, the bottom surface of the L-shaped fixing plate is provided with several fixing tubes, the inside of the fixing tubes is connected to the support feet by bolts, the L-shaped fixing plate is provided with several mounting holes, and four sets of mounting blocks are provided at equal intervals along the perimeter of the water tank near its center, and the four sets of mounting blocks are provided with through holes.

[0009] The above technical solution provides two installation methods: wall mounting and ceiling mounting. This allows the installation of the water tank to be unrestricted by the available space, increasing the flexibility and adaptability of the installation. The appropriate installation method can be selected according to different site conditions, saving space and improving the versatility of the equipment.

[0010] Furthermore, the filter assembly includes a filter box connected to the inlet via a flange. The filter box has several limiting grooves inside, and each limiting groove has a filter plate inside. The top of the filter plate has a stepped pull plate. The top of the filter box has a groove that matches the stepped pull plate. The filter box and the stepped pull plate are fixed in position by bolts.

[0011] The filter plates are arranged in three groups, and the three groups of filter plates are respectively provided with filter holes of different pore sizes;

[0012] The above technical solution, through multi-stage filter plates with different pore sizes, can more effectively filter impurities in wastewater and improve the filtration effect. The stepped pull plate and limiting groove design facilitate the installation, disassembly and replacement of the filter plates.

[0013] Furthermore, the other end of the filter box is connected to a connecting pipe, and a first flow meter is provided on the outside of the connecting pipe. The inlet of the connecting pipe is connected to the outlet of the membrane module through a flange.

[0014] By accurately controlling the wastewater flow rate, the wastewater treatment process can be effectively controlled and regulated, ensuring the stability of the treatment effect.

[0015] Furthermore, a second flow meter is provided outside the output port, a water quality sensor is provided inside the output port, and a scale is provided outside the water tank;

[0016] Through the above technical solution, the second flow meter monitors the flow rate of sewage at the outlet, the water quality sensor detects the quality of the output sewage, and the scale displays the liquid level of sewage in the water tank.

[0017] Furthermore, a controller is provided on one side of the water tank, and the controller is connected to a float sensor, a first flow meter, a second flow meter, a water quality sensor, and an air vent valve via signal lines.

[0018] The above technical solution receives signals from various sensors and flow meters, and controls equipment such as self-priming pumps and exhaust valves according to preset programs, thereby realizing the automated operation of the sewage treatment process.

The installation components allow for both wall-mounted and suspended installation, overcoming space limitations. Users can flexibly choose the appropriate installation method based on their actual usage scenarios and needs. Whether in a space-constrained underground location or an environment with specific equipment layout requirements, the priming tank can be easily installed, greatly improving the applicability and versatility of the equipment; 2. The priming tank is equipped with a float-type sensor that monitors the liquid level in real time and transmits the signal to the controller. This allows for timely monitoring of the water volume within the priming tank, enabling appropriate operations and adjustments. Simultaneously, a first flow meter outside the pipe continuously monitors the water flow entering the priming tank after passing through the filtration components, while a second flow meter outside the output port monitors the water flow output from the priming tank. A water quality sensor inside the output port continuously detects the quality indicators of the output water, such as turbidity, pH, and dissolved oxygen, and transmits this flow and water quality data to the controller. The controller analyzes and processes the received signals, enabling real-time monitoring of the wastewater treatment system's operating status and timely adjustment of treatment parameters to ensure that the wastewater treatment effect meets the required standards.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0029] Please see Figure 1-5 This embodiment provides a priming tank for increasing the suction lift of a wastewater treatment device, including a priming tank 1, an inlet 101 located near the top of the priming tank 1, an outlet 102 located at the bottom of the priming tank 1, a mounting assembly 2 on the priming tank 1, a float sensor 103 located inside the priming tank 1, an exhaust valve 104 located at the top of the priming tank 1, and a cover plate 105 located at the top of the priming tank 1 connected by a flange. The inlet 101 is connected to a filter assembly 3, the priming tank 1 is connected to a membrane assembly 106, and the priming tank 1 is connected to a self-priming pump 107.

[0030] When the membrane module 106 experiences temporary fluctuations due to various reasons, the water inlet tank 1 can replenish the water volume in a timely manner, ensuring that the self-priming pump 107 can continuously and stably pump out sewage according to the set flow rate. As the core container, the water inlet tank 1 provides space for liquid storage and transmission for the entire water treatment process. The inlet port 101 is used to receive water resources, the outlet port 102 is used for output, the float sensor 103 monitors the liquid level in the tank, the vent valve 104 discharges gas from the tank, and the cover plate 105 facilitates inspection and maintenance of the tank. The water inlet tank 1 connects the filter module 3, the membrane module 106, and the self-priming pump 107, realizing a complete process of water resources from input, treatment to output.

[0031] Meanwhile, in order to ensure that the installation of the water tank 1 is not limited by the space occupied, two installation methods are set through the installation component 2: wall mounting and hanging.

[0032] Mounting assembly 2 includes an L-shaped fixing plate 201 located at the bottom of the water tank 1. The bottom surface of the L-shaped fixing plate 201 has several fixing tubes 202. Support legs 203 are bolted to the inside of each fixing tube 202. The L-shaped fixing plate 201 has several mounting holes 204. Four sets of mounting blocks 205 are evenly spaced along the circumference of the water tank 1 near its center. Openings 206 penetrate the interior of each of the four sets of mounting blocks 205.

[0033] In practice, two installation methods are provided: wall-mounted and ceiling-mounted. The material of the pull rope is not specified as it depends on the specific circumstances.

[0034] Wall-mounted installation: First, fix the L-shaped fixing plate 201 to the wall through the mounting hole 204. Then, pass the pull rope through the opening 206 on the mounting block 205, lock one end to the water tank, and connect the other end to the wall with bolts to complete the wall-mounted installation.

[0035] Hoisting and installation: Use a rope to pass through the opening 206 and connect the other end to the ceiling to hoist the water tank. At the same time, the support feet 203 on the bottom of the L-shaped fixing plate can be moved along the fixing pipe 202 to support the support feet to the ground. Alternatively, holes can be made in the support feet 203 and bolts can be used to fix the position to enhance the stability of the installation.

[0036] like Figure 3 As shown, the filter assembly 3 includes a filter box 301 connected to the inlet 101 via a flange. The filter box 301 has several limiting grooves 302 inside, and each limiting groove 302 has a filter plate 303 inside. The top of each filter plate 303 has a stepped pull plate 304. The top of the filter box 301 has a groove that matches the stepped pull plate 304. The filter box 301 and the stepped pull plate 304 are fixed in position by bolts. Three sets of filter plates 303 are arranged, and each set of filter plates 303 has filter holes of different diameters.

[0037] Water enters the filter box 301 through the inlet 101 and passes through three sets of filter plates 303 with different pore sizes. Impurities of different particle sizes are intercepted on the corresponding filter plates 303. The filtered water enters the water tank 1. When the filter plates 303 need to be replaced or cleaned, the bolts are loosened and the filter plates 303 are removed from the limiting grooves 302 through the stepped pull plates 304.

[0038] like Figure 4 As shown, the other end of the filter box 301 is connected to a connecting pipe 305. A first flow meter 306 is installed on the outside of the connecting pipe 305. The inlet of the connecting pipe 305 is connected to the outlet of the membrane module 106 through a flange.

[0039] The water treated by the membrane module 106 is filtered again by the filter box 301 and flows into the water tank 1. The first flow meter 306 continuously monitors the flow rate of the water in the pipe 305 and transmits the flow data to the controller.

[0040] A second flow meter 108 is installed outside the output port 102, a water quality sensor 109 is installed inside the output port 102, and a scale is installed outside the water tank 1.

[0041] The self-priming pump 107 draws the treated water from the water tank 1 out of the outlet 102. The second flow meter 108 monitors the flow rate of the output water. The water quality sensor 109 detects the quality indicators of the output water and transmits the data to the controller. At the same time, the water level in the tank can be seen directly through the scale on the outside of the water tank 1.

[0042] A controller is provided on one side of the water tank 1. The controller is connected to the float sensor 103, the first flow meter 306, the second flow meter 108, the water quality sensor 109, and the air vent valve 104 via signal lines.

[0043] The working process of this utility model is as follows: When using this cultural dissemination and display device, firstly...

[0044] S1, Installation Phase

[0045] Determine the installation method: Based on the actual usage scenario and needs, choose either wall-mounted or ceiling-mounted installation.

[0046] Wall-mounted installation: First, fix the L-shaped fixing plate 201 to the wall through the mounting holes 204. Then, pass the pull rope through the opening 206 on the mounting block 205 near the center of the outside of the water tank 1 and fix it by bolts or other means. The other end of the pull rope is connected to the wall by bolts to complete the wall-mounted installation.

[0047] Hoisting and installation: Use a rope to pass through the opening 206 on the mounting block 205 and connect the other end to the ceiling to hoist the water tank 1. At the same time, the support feet 203 on the bottom of the L-shaped fixing plate can be moved along the fixing pipe 202 to support the support feet to the ground. Alternatively, holes can be made in the support feet 203 and bolts can be used to fix the position to enhance the stability of the installation.

[0048] S2, Wastewater Introduction and Preliminary Treatment Stage

[0049] Wastewater first enters membrane module 106, where the AO+MBR membrane process is used to remove suspended solids, colloids, bacteria, viruses, and some dissolved substances from the wastewater, allowing freshwater to permeate through the membrane, thus purifying the wastewater.

[0050] Water treated by membrane module 106 enters filter box 301 through inlet pipe 305. After entering the filter box from inlet 101, the water passes through three sets of filter plates 303 with different pore sizes to further remove impurities and prevent clogging of self-priming pump 107. When it is necessary to replace or clean filter plates 303, loosen the bolts between the top of filter box 301 and stepped pull plate 304, and remove the filter plate from limiting groove 302 through stepped pull plate.

[0051] Filter component 3 can be set or not depending on the actual situation.

[0052] S3, Water Tank Storage and Monitoring Phase

[0053] After secondary filtration by the filtration components, the water enters the water inlet tank 1. Water inlet tank 1 serves as the core container, providing space for temporary liquid storage and transport throughout the entire water treatment process.

[0054] The float sensor 103 inside the water tank floats up and down with the change of liquid level in the tank. When the liquid level rises or falls, the float triggers the sensor, which transmits the liquid level signal to the controller through a signal line.

[0055] During the process of water entering the water intake tank, air may be introduced or gas may be generated inside the tank. When the gas inside the water intake tank accumulates to a certain level, the exhaust valve 104 at the top automatically opens to discharge the gas outside the tank, preventing the gas accumulation inside the tank from affecting the normal operation of the self-priming pump 107. After the gas is discharged, the pressure inside the tank returns to normal, and the exhaust valve 104 automatically closes.

[0056] A first flow meter 306 outside the flow pipe 305 continuously monitors the flow rate of water entering the water tank after passing through the filter assembly and transmits the flow data to the controller. Similarly, a second flow meter 108 outside the output port 102 monitors the flow rate of water exiting the water tank and also transmits the data to the controller.

[0057] The water quality sensor 109 inside the output port 102 detects the quality indicators of the output water resources in real time, such as turbidity, pH, dissolved oxygen, etc., and transmits the water quality signal to the controller.

[0058] S4, Water Resource Output Stage

[0059] The self-priming pump 107 starts, creating a negative pressure in the water tank 1, which draws the treated water from the outlet 102 and transports it through pipelines to subsequent treatment stages such as the clear water tank.

[0060] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is through a controller. The control circuit of the controller can be realized by a person skilled in the art through simple circuit connection. It is common knowledge in the field. Therefore, this application will not explain the control method and circuit connection in detail.

[0061] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
