Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to an overflow-proof microbial sewage treatment pool. Background Art

[0002] In modern industrial production and production life, a large amount of various types of sewage will be generated. At present, sewage treatment plants mostly use microbial treatment methods to harmlessly treat sewage and purify it into reusable domestic or industrial water. Microbial treatment methods usually use activated sludge method or biofilm method for sewage treatment, both of which require the cultivation of a large number of microorganisms in the pool, and the use of microorganisms to degrade organic matter in sewage, degrading it into gases such as ammonia and discharge it. When heavy rain occurs, rainwater entering the pool will change the organic matter content in the pool, affecting the metabolism and degradation efficiency of microorganisms. After heavy rain, the nitrogen and phosphorus concentrations in the water body may rise sharply, affecting the normal metabolism of microorganisms. At the same time, heavy rain may cause the water level in the treatment pool to rise sharply, causing the risk of water overflow.

[0003] For example, a self-defoaming microbial sewage treatment pool with publication number CN110615522A has a structure including a pool body, a plurality of aeration pipes are embedded in the inner bottom of the pool body, a plurality of air outlets connected to the aeration pipes are opened in the inner bottom of the pool body, a first one-way valve is installed in the air outlet, a stainless steel pipe is rotatably connected to the center of the inner bottom of the pool body, a slider is sealingly and slidably connected in the stainless steel pipe, a water inlet is opened at the upper end of the stainless steel pipe, and a second one-way valve is installed in the water inlet, a plurality of spray pipes connected thereto are fixedly connected to the upper end of the stainless steel pipe, and a circular groove connected to the aeration pipe is opened on the side wall of the pool body. The above-mentioned filter tank uses gas to push the slider upward in the stainless steel pipe to spray water, so that high-frequency vibration when the water pump is working will not be generated, so as to improve the defoaming effect. However, it cannot solve the problem of decreased microbial activity and water overflow in the sewage treatment tank during heavy rain. Therefore, this application designs an anti-overflow microbial sewage treatment tank that can seal the upper part of the tank body, use gravity and air pressure difference to divert and collect rainwater, and discharge waste gas.

DETAILED DESCRIPTION

[0027] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0028] like Figures 1 to 9 As shown, the present application proposes an overflow-proof microbial sewage treatment pool, comprising a pool body 1, a gallery bridge 2, an exhaust mechanism 3 and a double-layer folding membrane mechanism 4 for closing the upper part of the pool body 1; the lower part of the gallery bridge 2 is fixedly connected to the upper end of the pool body 1, and the double-layer folding membrane mechanism 4 is rotatably connected to the pool body 1; an upper plate 5 and a lower plate 6 are arranged in the double-layer folding membrane mechanism 4, the exhaust mechanism 3 is rotatably connected to the upper end of the upper plate 5, one end of the lower plate 6 is slidably connected to the inner wall of the pool body 1, and the other end of the lower plate 6 is rotatably connected to the middle part of the pool body 1, the upper plate 5 is fixedly connected to the pool body 1, and the lower plate 6 is positioned at the lower part of the upper plate 5, and the upper plate 5 and the lower plate 6 are both inclined; the lower plate 6 rotates in a circle with the middle part of the pool body 1 as the axis, pulling the double-layer folding membrane mechanism 4 to rotate and unfold, so as to form an inverted cone spiral membrane body to close the upper end of the pool body 1, and the exhaust mechanism 3 is driven by wind and water flow to discharge the waste gas of the pool body 1 at the lower part of the double-layer folding membrane mechanism 4.

[0029] See also Figures 1 to 4 A column 11 is fixedly arranged in the middle of the pool body 1, one end of the corridor bridge 2 is fixedly connected to the upper end of the column 11, and the other end of the corridor bridge 2 is fixedly connected to the side of the pool body 1. A vertical drainage groove 12 is opened in the side wall of the pool body 1. Through the corridor bridge 2, the operator can perform daily inspection and maintenance operations on the inside of the pool body 1 and the double-layer folding membrane mechanism 4. After the double-layer folding membrane mechanism 4 is unfolded, rainwater flows down along the inverted cone spiral membrane to the drainage groove 12 for discharge. The inside of the drainage groove 12 can be connected to the rainwater treatment pool, or the rainwater can be directly discharged.

[0030] As another example, Figures 1 to 5As shown, one end of the upper plate 5 is fixedly connected to the column 11, the other end of the upper plate 5 is fixedly connected to the side wall of the pool body 1, one end of the lower plate 6 is rotatably connected to the column 11, a motor is arranged in the column 11, the output end of the motor is plugged into the lower plate 6, the other end of the lower plate 6 is slidably connected to the side of the pool body 1 through the slide groove 13, and a plurality of slide rails 111 are provided in the middle of the column 11. In the initial state, the double-layer folding membrane mechanism 4 is positioned between the upper plate 5 and the lower plate 6 in a folded and stacked form, and its weight is borne by the lower plate 6; wherein a rain sensing device is arranged on the corridor bridge 2, when rainy weather occurs, the rain sensing device sends an electrical signal to the motor, the motor starts to drive the lower plate 6 to rotate around the column 11, and the far end of the lower plate 6 slides in the slide groove 13 on the inner wall of the pool body 1, driving the double-layer folding membrane mechanism 4 to unfold.

[0031] See also Figure 2 The double-layer folding membrane mechanism 4 and the exhaust mechanism 3 are both positioned under the corridor bridge 2, so that when not in use, the double-layer folding membrane mechanism 4 and the exhaust mechanism 3 do not affect the daily use of the microbial treatment pool and the operators' observation of the inside of the pool body 1, and when rainy weather occurs, the rainwater will not flow into the inside of the pool body 1 through the exhaust mechanism 3 due to the obstruction of the corridor bridge 2.

[0032] As another example, Figures 1 to 4 as well as Figure 7 As shown, the double-layer folding membrane mechanism 4 includes an upper membrane 41, a lower membrane 42, a side plate 43 and an array of folding support rods 44. One end of the upper membrane 41 is connected to the side of the upper plate 5, and the other end of the upper membrane 41 is connected to the side of the lower membrane 42; one end of the lower membrane 42 is connected to the side of the upper plate 5, and the other end of the lower membrane 42 is connected to the side of the lower plate 6. The upper part of the folding support rod 44 is fixedly connected to the lower wall of the upper membrane 41, and the lower part of the folding support rod 44 is fixedly connected to the upper wall of the lower membrane 42. The folding support rod 44 is evenly arranged between the upper plate 5 and the lower plate 6 to form a fan-shaped structure; one end of the folding support rod 44 is slidably connected to the column 11 through the slide rail 111, and the upper end of the side plate 43 is fixedly connected to the end of the upper plate 5 away from the upper membrane 41. The folding support rod 44 is evenly arranged from top to bottom, and is narrower near the end of the column 11 and gradually widens as it extends outward. The connection between the folding support rod 44 and the column 11 can also be a circular rotating connection.

[0033] When the lower plate 6 rotates and moves, the lower plate 6 drives the upper membrane 41 and the lower membrane 42 to move synchronously, thereby driving the folding support rod 44 to move in a circular motion, driving the overall structure to unfold, and when the lower plate 6 moves in the opposite direction, the overall structure is folded and stored back into the space between the upper plate 5 and the lower plate 6.

[0034] The parts of the upper membrane 41 and the lower membrane 42 located on the side wall of the pool body 1 are made of rubber material, which is not easy to wear and tear and prevents rainwater from falling into the pool body 1 through the gap, thereby achieving an effective sealing effect.

[0035] See also Figure 3 and Figure 4 The lower end of the side plate 43 contacts the lower plate 6, a latch 431 is provided at the lower end of the side plate 43, and an arc-shaped latching groove 61 corresponding to the latching groove 431 is provided on the upper surface of the lower plate 6. In the initial state, the side of the lower plate 6 contacts the side plate 43. When the lower plate 6 moves to drive the upper membrane 41 and the lower membrane 42 to unfold, the lower plate 6 moves in a circle and moves to the side of the side plate 43 away from the upper plate 5. The latching groove 61 at the lower end of the side plate 43 is inserted into the arc-shaped latching groove 61 to achieve the connection between the lower plate 6 and the side plate 43. When it rains, the rainwater moves along the inverted cone spiral structure formed by the upper membrane 41, passes through the limit of the side plate 43, and finally flows into the drainage groove 12 along the lower plate 6.

[0036] See also Figure 6 , the upper film 41 and the lower film 42 are both provided with folds for easy folding at the folding support rod 44, and the inner wall of the lower film 42 is provided with a heating wire. After the upper film 41 and the lower film 42 are unfolded, a cover is formed on the upper end of the pool body 1. Due to the design of the double-layer film body, a certain degree of heat preservation is played on the lower part of the lower film 42, and under the influence of heavy rain weather, the air pressure and temperature are reduced, making the air pressure difference between the upper part of the upper film 41 and the lower part of the lower film 42 more obvious; the ammonia and other gases produced by the microorganisms in the pool body 1 are affected by the air pressure and spirally rise along the inverted cone spiral structure formed by the lower film 42, and are finally discharged at the upper plate 5.

[0037] When the amount of gas at the lower end of the lower membrane 42 is large, or the pressure difference is not obvious enough to efficiently discharge the gas, the heating wire 421 can be started to heat the lower membrane 42 and the lower air through the heating wire 421, so that the temperature difference between the upper part of the upper membrane 41 and the lower part of the lower membrane 42 is more obvious, forming a more efficient gas passage.

[0038] As another example, Figures 4 to 9 As shown, the exhaust mechanism 3 includes a wind cup 31, a through slot 32, a vertical rod 33, an arc-shaped connecting rod 34, a turbine 35 and an auxiliary drive assembly 36; the through slot 32 is opened at the upper end of the upper plate 5, the turbine 35 is rotatably connected to the inner wall of the upper plate 5 through the through slot 32, the lower end of the vertical rod 33 is fixedly connected to the middle of the turbine 35, the lower end of the arc-shaped connecting rod 34 is fixedly connected to the vertical rod 33, the upper end of the arc-shaped connecting rod 34 is fixedly connected to the wind cup 31, and the wind cup 31 and the arc-shaped connecting rod 34 are evenly arranged in an array around the circumference; the auxiliary drive assembly 36 is plugged into the lower end of the middle of the turbine 35.

[0039] The wind cups 31 can be arranged in multiple groups, and a corresponding number of arc-shaped connecting rods 34 are arranged. The through grooves 32 are opened at the upper end of the upper plate 5 and the lower end of the corridor bridge 2, so that rainwater will not flow back into the lower part of the upper plate 5 in rainy weather. The side periphery of the through grooves 32 is further arranged to extend upward to prevent water on the surface of the upper plate 5 from entering the through grooves 32.

[0040] After the device is fully deployed, due to the shielding of the corridor bridge 2 above the wind cup 31, the wind direction usually passes through the corridor bridge 2 at an angle close to the horizontal direction, driving the wind cup 31 to rotate. The directions of the multiple groups of wind cups 31 are arranged in a circle, so that the wind cup 31 can only rotate in one direction. The rotation of the wind cup 31 drives the arc-shaped connecting rod 34 and the vertical rod 33 to rotate synchronously, thereby driving the turbine 35 to rotate. The rotation of the turbine 35 extracts the ammonia and other gases gathered under the lower plate 6 to the top of the upper plate 5 for discharge; the gas assists in driving the arc-shaped connecting rod 34 to rotate and displace in the process of rising in the through groove 32. After the gas rises to the outside of the through groove 32, it is scattered and disturbed by the rotating wind cup 31 to prevent it from gathering in a smaller area and causing danger to the workers passing through the corridor bridge 2.

[0041] See also Figure 5 , Figure 8 as well as Fig. 9 The auxiliary drive assembly 36 includes a driving gear 361, a toothless gear 362, an impeller 363, a synchronous belt 364, a first pulley 365 and a second pulley 366; one end of the impeller 363 is rotatably connected to the inner wall of the drainage groove 12, the other end of the impeller 363 is plugged into the first pulley 365 through a connecting rod, the second pulley 366 is rotatably connected to the inner wall of the side plate 43, and the first pulley 365 and the second pulley 366 are connected by a synchronous belt 364; the second pulley 366 is plugged into the toothless gear 362 through a connecting rod, the upper end of the driving gear 361 is plugged into the middle part of the lower end of the turbine 35 through a connecting rod, and the driving gear 361 cooperates with the toothless gear 362.

[0042] After the device is fully unfolded, the water flows downward in a spiral through the upper membrane 41, and enters the drainage groove 12 along the lower plate 6 under the limitation of the side plate 43. When the water flows into the drainage groove 12, the impeller 363 is driven to rotate, and the impeller 363 drives the first pulley 365 to rotate. The first pulley 365 transmits the rotation to the second pulley 366 through the synchronous belt 364. The second pulley 366 drives the toothless gear 362 to rotate. The toothless gear 362 intermittently drives the driving gear 361 to accelerate its rotation during rotation. The driving gear 361 synchronously drives the turbine 35 to rotate with the synchronous belt 364, thereby providing a second power for the turbine 35.

[0043] Among them, the use of the toothless gear 362 allows the toothless gear 362 to stop rotating when the rainwater is relatively thin and the water flow is insufficient to drive the impeller 363 to rotate, or to overcome the friction of the transmission system, and does not mesh with the driving gear 361, and does not affect the force of the wind cup 31 to drive the turbine 35 to rotate, thereby reducing the gas discharge efficiency.

[0044] It should be noted that the side plate 43 is communicated with the interior of the drain groove 12 , the side plate 43 is communicated with the interior of the upper plate 5 , and the driving gear 361 is positioned inside the upper plate 5 .

[0045] Working principle: Under normal conditions, the double-layer folding membrane mechanism 4 is stored under the corridor bridge 2, and the upper membrane 41 and the lower membrane 42 are folded and positioned between the upper plate 5 and the lower plate 6. When the rainfall sensing device senses the set value of rain, the motor starts to drive the lower plate 6 to rotate and unfold the double-layer folding membrane mechanism 4, and the lower plate 6 drives the upper membrane 41 and the lower membrane 42 to move synchronously, thereby driving the folding support rod 44 to move in a circular motion, driving the overall structure to unfold; the rainwater converges downward along the inverted cone spiral structure formed by the upper membrane 41, and finally flows into the drainage trough 12 along the lower plate 6 after passing through the limit of the side plate 43.

[0046] Due to the design of the double-layer membrane body, a certain degree of heat preservation is provided to the lower part of the lower membrane 42, and under the influence of the heavy rain, the air pressure and temperature are reduced, so that the air pressure difference between the upper part of the upper membrane 41 and the lower part of the lower membrane 42 is more obvious; the ammonia and other gases produced by the microorganisms in the pool body 1 are affected by the air pressure and spirally rise along the inverted cone spiral structure formed by the lower membrane 42, and are finally discharged at the upper plate 5; the wind drives the wind cup 31 to rotate, and drives the turbine 35 to rotate through the arc-shaped connecting rod 34 and the vertical rod 33, and the turbine 35 rotates to extract the ammonia and other gases gathered under the lower plate 6 to the upper part of the upper plate 5, and discharge them and disperse and disturb them through the rotating wind cup 31;

[0047] When water flows into the drainage trough 12 , the impeller 363 is driven to rotate, and the impeller 363 drives the first pulley 365 to rotate, which drives the toothless gear 362 to rotate and intermittently drives the driving gear 361 to accelerate the rotation. The driving gear 361 synchronously drives the turbine 35 with the belt 364 to rotate, providing the turbine 35 with a second power.
