Description

Technical Field

[0001] This utility model relates to the field of pulse aerator technology, and in particular to an adaptive MBR curtain membrane module matching gas collection pulse aerator. Background Technology

[0002] A conventional pulse aerator has a rectangular structure. Air is compressed by a blower, enters the air inlet, and flows into the air collection box, where it rises and accumulates.

[0003] However, conventional pulse aerator equipment has a single-flow pulse distributor at the top, and the air volume distribution varies between air outlets at different distances. This results in inconsistent aeration volume between air outlets at different distances, causing a decrease in aeration uniformity and thus affecting the aeration effect. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an adaptive MBR curtain membrane module matching gas collection pulse aerator, which can solve the problem that the pulse distributor at the top of the conventional pulse aerator equipment is a single flow, and there are differences in the air volume distribution of the air outlets at different distances. This results in inconsistent aeration volume at different distances of the air outlets during aeration, causing a decrease in the uniformity of aeration, thereby affecting the aeration effect.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adaptive MBR curtain membrane module with a matching gas-collecting pulse aerator, including a gas collection box, with multiple sludge discharge holes communicating with the gas collection box on both the left and right sides.

[0008] Among them, by setting multiple sludge discharge holes, when the equipment is stopped and restarted, the sludge that has flowed back into the air box can be blown out through the sludge discharge holes to ensure that the air passage is unobstructed.

[0009] The upper surface of the gas collection box is fixedly equipped with a detachable top plate, and three pulse distributors are fixedly connected to the upper surface of the detachable top plate.

[0010] Preferably, the lower surfaces of the three pulse distributors all penetrate the lower surface of the detachable top plate, the upper surfaces of the three pulse distributors are provided with four pulse air outlets, and the air inlets on the lower surfaces of the three pulse distributors are all fixedly connected to a first connecting pipe.

[0011] Preferably, the inner walls of the three first connecting tubes are slidably fitted with second connecting tubes.

[0012] Preferably, the bottom of the gas collection box is provided with a gas collection silicone rubber air passage, and the front surface of the gas collection silicone rubber air passage is fixedly connected to an air inlet pipe communicating with it, with the front end of the air inlet pipe extending through the front surface of the gas collection box.

[0013] Preferably, the front end of the air inlet pipe is fixedly connected to an air inlet communicating with it, and the upper surface of the air collecting silicone rubber air passage is fixedly connected to three mounting pipes communicating with it.

[0014] Preferably, the three second connecting pipes are fixedly connected to the corresponding mounting pipes, and the three second connecting pipes communicate with the corresponding mounting pipes.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The adaptive MBR curtain membrane module is equipped with a gas-collecting pulse aerator. The pulse distributor at the top of the detachable top plate is arranged in a matrix of three chambers in parallel. The air inlet chamber is relatively independent and closed. The pulse outlet is set as an arc-shaped air path strip-shaped air hole, which can ensure effective air collection and uniform pulse air output, thereby improving the aeration effect.

[0018] (2) The adaptive MBR curtain membrane module is equipped with a gas-collecting pulse aerator. When the gas pressure in the gas-collecting silicone rubber air channel reaches a certain value, the three pressure valves will automatically open, and the gas in the gas-collecting silicone rubber air channel will escape, forming a pulse aeration effect. When a certain amount of gas escapes, the pressure decreases and the three pressure valves will automatically close, and the gas-collecting silicone rubber air channel will continue to be filled with gas. This process is repeated to form a pulse aeration. This structural design does not require precise horizontal calibration of the entire membrane frame and has very strong applicability.

[0019] (3) The adaptive MBR curtain membrane module is equipped with a gas-collecting pulse aerator. By setting multiple sludge discharge holes, when the equipment is stopped and restarted, the sludge backflowing in the air box can be blown out through the sludge discharge holes, ensuring smooth air passage and improving the practicality of the gas-collecting pulse aerator.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Please see Figure 1-4 This utility model provides a technical solution: an adaptive MBR curtain membrane module with a gas collection pulse aerator, including a gas collection box 1, and multiple sludge discharge holes 2 communicating with the gas collection box 1 on both the left and right sides.

[0031] Among them, by setting multiple sludge discharge holes 2, when the equipment is stopped and restarted, the sludge that flows back into the air box can be blown out through the sludge discharge holes to ensure that the air passage is unobstructed.

[0032] Among them, a detachable top plate 6 is fixedly installed on the upper surface of the gas collection box 1, and three pulse distributors 4 are fixedly connected to the upper surface of the detachable top plate 6.

[0033] Furthermore, the lower surfaces of the three pulse distributors 4 all penetrate the lower surface of the detachable top plate 6, the upper surfaces of the three pulse distributors 4 are provided with four pulse air outlets 5, and the air inlets of the lower surfaces of the three pulse distributors 4 are all fixedly connected to the first connecting pipe 11.

[0034] Furthermore, the inner walls of the three first connecting pipes 11 are all slidably fitted with second connecting pipes 12.

[0035] Furthermore, the bottom of the gas collection box 1 is provided with a gas collection silicone rubber air passage 13, and the front surface of the gas collection silicone rubber air passage 13 is fixedly connected with an air inlet pipe 9 communicating with it. The front end of the air inlet pipe 9 extends through the front surface of the gas collection box 1.

[0036] Furthermore, the front end of the air intake pipe 9 is fixedly connected to an air inlet 8 that communicates with it, and the upper surface of the air collecting silicone rubber air passage 13 is fixedly connected to three mounting pipes 14 that communicate with it.

[0037] Furthermore, the three second connecting pipes 12 are fixedly connected to the corresponding mounting pipes 14, and the three second connecting pipes 12 are in communication with the corresponding mounting pipes 14.

[0038] Furthermore, when using an adaptive MBR curtain membrane module with a gas-collecting pulse aerator, it is first fixed in the designated position using strap bolts through the fixing holes 7 on the three fixing plates 3, and then connected to the outside through the air inlet 8. When gas enters the interior of the gas-collecting silicone rubber air passage 13 through the air inlet 8 and the air inlet pipe 9, the gas-collecting silicone rubber air passage 13 is in a soft, collapsed state when the gas pressure is low (e.g., Figure 3 As shown), when the gas collecting silicone rubber air passage 13 is slowly inflated, the air pressure increases, and the gas collecting silicone rubber air passage 13 gradually fills and expands (as shown). Figure 4As shown, when the gas collecting silicone rubber air passage 13 gradually fills and expands, it pushes the three mounting pipes 14 upwards. As the three mounting pipes 14 move upwards, they push the three second connecting pipes 12 into the inner wall of the three first connecting pipes 11. When the gas pressure inside the gas collecting silicone rubber air passage 13 reaches a certain value, the three pressure valves 10 automatically open, and the gas inside the gas collecting silicone rubber air passage 13 escapes, creating a pulse aeration effect. The gas then enters the interior of the three pulse distributors 4 through the second connecting pipes 12 and the first connecting pipes 11, and then through the three... The pulse air is discharged through the pulse outlet 5 on the pulse distributor 4. The pulse distributor 3 at the top of the detachable top plate 6 is arranged in a matrix of three parallel chambers. The air inlet chamber is relatively independent and closed. The pulse outlet 5 is set as an arc-shaped air path strip-shaped air hole, which can ensure effective air intake and collection and uniform pulse air output, thereby improving the aeration effect. When a certain amount of gas escapes, the pressure decreases and the three air pressure valves 10 will automatically close. The air collection silicone rubber air channel 13 continues to be filled with air. This process is repeated to form a pulse aeration. This structural design does not require precise horizontal calibration of the entire membrane frame and has very strong applicability.

[0039] Working principle: When using an adaptive MBR curtain membrane module with a gas-collecting pulse aerator, it is first fixed in the designated position through the fixing holes 7 on the three fixing plates 3 using strap bolts. Then, it is connected to the outside through the air inlet 8. When gas enters the interior of the gas-collecting silicone rubber air passage 13 through the air inlet 8 and the air inlet pipe 9, the gas-collecting silicone rubber air passage 13 is in a soft, collapsed state when the gas pressure is low (e.g., Figure 3 As shown), when the gas collecting silicone rubber air passage 13 is slowly inflated, the air pressure increases, and the gas collecting silicone rubber air passage 13 gradually fills and expands (as shown). Figure 4 As shown, when the gas collecting silicone rubber air passage 13 gradually fills and expands, it will push the three mounting pipes 14 upward. When the three mounting pipes 14 move upward, they will push the three second connecting pipes 12 into the inner wall of the three first connecting pipes 11. When the gas pressure in the gas collecting silicone rubber air passage 13 reaches a certain value, the three pressure valves 10 will automatically open, and the gas in the gas collecting silicone rubber air passage 13 will escape, forming a pulse aeration effect. The gas enters the interior of the three pulse distributors 4 through the second connecting pipes 12 and the first connecting pipes 11, and then is discharged through the pulse outlet holes 5 on the three pulse distributors 4. When a certain amount of gas escapes, the pressure decreases and the three pressure valves 10 will automatically close, and the gas collecting silicone rubber air passage 13 will continue to be filled with gas.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
