Description

Technical Field

[0001] The invention relates to the technical field of aerators, and in particular to a wastewater stainless steel coarse-pore aerator with airflow vibration cleaning function. Background Art

[0002] The microporous aerator has the advantages of high oxygen transfer efficiency, low energy consumption, and large oxygen contact area. However, it should be noted that when gas is filled into the microporous aerator, there is an obvious pressure difference (water pressure and air pressure) at the local position of the corresponding micropores. Specifically, in order to ensure gas discharge, the gas pressure is greater than the water pressure. When the gas filling is stopped, the local position of the corresponding micropores "instantly loses" air pressure, causing the sewage to quickly flow back and be "sucked" into the aerator. Solid impurities in the sewage simultaneously enter the aerator. During long-term use, as the amount of solid impurities sucked in continues to increase, the fluidity of the air flow channel inside the aerator is reduced, which directly affects the use effect of the aerator.

[0003] It should also be noted that the smaller the aperture of the air outlet in the aerator, the smaller the bubbles produced. The smaller the bubbles, the better the aeration effect. However, the smaller the aperture, the more likely it is to be clogged, and even cause complete blockage of the micropores in local locations.

[0004] This application proposes a solution to this problem. Summary of the invention

[0005] The purpose of the present invention is to provide a stainless steel coarse-pore aerator for wastewater with airflow vibration cleaning function. The conventional structure of the microporous aerator is explained. Because there is a water pressure / air pressure imbalance problem in the aeration process, the solid impurities are accelerated to be sucked into the aerator under the action of water pressure, causing blockage, which directly affects the aeration efficiency of the aerator.

[0006] The purpose of the present invention can be achieved by the following technical scheme: a wastewater stainless steel coarse-pore aerator with airflow vibration cleaning function, comprising an assembly pipe and an air injection port arranged on one side of the upper end of the assembly pipe, wherein an internal pipe is slidably installed inside the assembly pipe along its length direction, and the internal positions of the assembly pipe corresponding to the two ends of the internal pipe are arranged as air limiting bins; An open sleeve is installed at the lower side of the assembly tube and is linearly and equidistantly arranged along its length direction. The built-in tube is provided with built-in microholes corresponding to the open sleeves. An auxiliary guide rod is installed inside the assembly tube. The setting direction of the auxiliary guide rod is parallel to the length direction of the assembly tube, and the auxiliary guide rod is arranged in a circular array along the center point of the assembly tube. A butterfly fin is installed at the position of the auxiliary guide rod corresponding to the inside of the built-in tube. The butterfly fin is in the shape of a curved arc to the left or right. The caliber of the built-in microholes is smaller than the inner diameter of the open sleeve. A primary air vent is opened at one end of the built-in tube corresponding to the gas injection port. The built-in tube and the auxiliary guide rod are slidably connected.

[0007] It is further configured that: a sealing ring corresponding to the inner wall of the assembly pipe is arranged at the outer wall of the built-in pipe.

[0008] It is further configured as follows: a winding electromagnetic coil group, a permanent magnet and a directional ring are arranged inside the air limiting chamber, the winding electromagnetic coil group is installed on one side of the assembly tube, the permanent magnet is installed at both ends of the built-in tube, and the directional ring is located in the middle of the winding electromagnetic coil group and the permanent magnet and is fixedly connected to the assembly tube.

[0009] It is further configured as follows: the auxiliary guide rod is hollow, and a secondary vent hole is provided at a position of the auxiliary guide rod corresponding to the air limiting bin.

[0010] It is further configured as follows: a metal ball sleeve is installed on the directional ring sheet, the number of the metal ball sleeves is equal to the number of the auxiliary guide rods, and the metal ball sleeves are distributed in a ring array along the center point of the built-in tube and are staggered with the auxiliary guide rods.

[0011] It is further configured as follows: a plurality of built-in balls are arranged in the metal ball sleeve, and the diameters of the plurality of built-in balls are not equal.

[0012] It is further configured as follows: directional blocks are installed at both ends of the built-in tube, the directional blocks are slidably connected to the inner wall of the assembly tube, and a ball head rod is installed at the position of the directional block corresponding to the directional ring piece.

[0013] The present invention has the following beneficial effects: 1. The overall structure makes two improvements to the conventional aerator in terms of caliber limitation and vibration. The improvement method of caliber limitation is as follows: the overall structure includes an assembly pipe and an internal pipe. The internal pipe, as the key aeration structure, still adopts the microporous aeration method, but the internal micropores are stored in the assembly pipe, and the open sleeve contacts the wastewater medium, thereby avoiding "excessive" clogging of the micropores by impurities during use; 2. The description of the added vibration method is: the overall structure utilizes the flow process of compressed gas during the aeration process, specifically utilizes the air pressure of the compressed gas itself, to realize the linear motion process of the built-in tube relative to the assembly tube, and installs a permanent magnet and a winding electromagnetic coil group in the air limiting chamber, utilizes the suction / repulsion between the two, and cooperates with the balance / imbalance of air pressure and suction / repulsion to complete the instantaneous aeration action, and in the process of compressed gas flow, the compressed gas directly acts on the butterfly wing, causing each butterfly wing to vibrate irregularly and generate a "vibration sense", and the "vibration sense" acts on the compressed gas, so that under the two-way action of the instantaneous aeration action and the "vibration sense", the cleaning purpose of vibration "removal of impurities" is achieved.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1: For conventional aerators, solid impurities in wastewater can easily cause local blockage of micropores in the aerator during the sedimentation process, and even cause complete blockage of micropores at local locations and "loss" of aeration capacity. In addition, when compressed gas is quickly blown in and stopped, there is an obvious pressure difference in the associated hydraulic / air pressure at the micropores. Under the action of the pressure difference, part of the wastewater or solid impurities are quickly filled into the aerator, which not only pollutes the interior of the aerator, but also further causes micropore blockage. This application proposes a solution.

[0019] Reference Figures 1 to 6 The wastewater stainless steel coarse-pore aerator with airflow vibration cleaning function in this embodiment includes an assembly pipe 1 and an air injection port 3 arranged on one side of the upper end of the assembly pipe 1. An internal pipe 7 is slidably installed inside the assembly pipe 1 along its length direction, and the internal positions of the assembly pipe 1 corresponding to the two ends of the internal pipe 7 are set as air limiting bins; An open sleeve 2 is installed at the lower side of the assembly tube 1 and is linearly and equidistantly arranged along its length direction. Built-in micropores 9 corresponding to the open sleeve 2 are opened on the built-in tube 7. An auxiliary guide rod 10 is installed inside the assembly tube 1. The setting direction of the auxiliary guide rod 10 is parallel to the length direction of the assembly tube 1, and the auxiliary guide rod 10 is arranged in a circular array along the center point of the assembly tube 1. A butterfly fin 11 is installed at the position of the auxiliary guide rod 10 corresponding to the inside of the built-in tube 7. The butterfly fin 11 is in the shape of a curved arc to the left or right. The caliber of the built-in micropore 9 is smaller than the inner diameter of the open sleeve 2. A primary vent is opened at one end of the built-in tube 7 corresponding to the gas injection port 3. The built-in tube 7 and the auxiliary guide rod 10 are in sliding connection. A sealing ring 6 corresponding to the inner wall of the assembly tube 1 is arranged on the outer wall of the built-in tube 7.

[0020] Working principle: First refer to Figure 3 To illustrate, the operation process of the aerator in this embodiment is basically the same as that of the conventional aerator structure, and compressed gas is blown into the interior of the assembly pipe 1 from the gas injection port 3. However, the difference from the conventional aerator structure is that: first, the overall structure is composed of the assembly pipe 1 and the built-in pipe 7, wherein the built-in pipe 7 is a key structure in the aeration process, and it still adopts the microporous aeration method, which is specifically embodied in the built-in micropores 9. When aeration is performed in a small-diameter manner, the smaller the bubbles generated, the better the aeration effect. However, the built-in micropores 9 are not in a continuously "exposed" state, but in a state of being stored inside the assembly pipe 1, and the inner diameter of the opening sleeve 2 on the assembly pipe 1 is much larger than the built-in micropores 9. The purpose of this is to prevent the built-in micropores 9 from being quickly blocked by impurities in the wastewater; A brief explanation is needed for this: further limiting the setting position of the opening sleeve 2, specifically limiting the installation method of the overall aerator by limiting the setting position of the opening sleeve 2. For example, when the aerator is set at the bottom of the wastewater treatment tank, the opening sleeve 2 is in the lower position. This method prevents impurities from directly settling into the opening sleeve 2.

[0021] Embodiment 2: This embodiment explains the gas limiting chamber in Embodiment 1: A winding electromagnetic coil group 8, a permanent magnet 5 and a directional ring piece 4 are arranged inside the air limiting bin. The winding electromagnetic coil group 8 is installed on one side of the assembly tube 1, and the permanent magnet 5 is installed at both ends of the built-in tube 7. The directional ring piece 4 is located in the middle position between the winding electromagnetic coil group 8 and the permanent magnet 5 and is fixedly connected to the assembly tube 1. The auxiliary guide rod 10 is hollow, and a secondary vent is opened at the position of the auxiliary guide rod 10 corresponding to the air limiting bin.

[0022] Referring to the technical content in the first embodiment, when the compressed gas is injected, there are the following movement modes: S1: Reference Figure 3 When the compressed gas is filled into the assembly pipe 1, the air pressure generated by the compressed gas can push the built-in pipe 7 to move to the left relative to the assembly pipe 1 until the built-in micropores 9 on the built-in pipe 7 intersect with the open sleeve 2, and the compressed gas is ejected from the built-in micropores 9 to form tiny bubbles; S2: Combined with the content of S1, the compressed gas mainly generates pressure on the built-in tube 7 toward the left side, and then the winding electromagnetic coil group 8 in the corresponding left position of the air limiting chamber is energized to generate magnetic force, and what needs to be further restricted is: it is necessary to ensure that a repulsive force is formed between the magnetic force generated by the winding electromagnetic coil group 8 and the permanent magnet 5 at the left side of the built-in tube 7, and the repulsive force generated is greater than or equal to the pressure generated by the compressed gas on the built-in tube 7, and then the built-in tube 7 is difficult to maintain the trend of moving to the left side. On the contrary, when the repulsive force in the left air limiting chamber "instantly disappears", the high pressure generated by the compressed gas is used to instantly push the built-in tube 7 to move to the left, thereby achieving the purpose of instant aeration.

[0023] Embodiment 3: This embodiment combines the technical content in Embodiment 1 to explain the injection process of compressed gas as follows: A metal ball sleeve 12 is installed on the directional ring piece 4, and the number of the metal ball sleeves 12 is equal to the number of the auxiliary guide rods 10, and the metal ball sleeves 12 are distributed in a circular array along the center point of the built-in tube 7 and are staggered with the auxiliary guide rods 10. A plurality of built-in balls 15 are arranged in the metal ball sleeve 12, and the diameters of the plurality of built-in balls 15 are not equal. Orientation blocks 13 are installed at both ends of the built-in tube 7, and the orientation blocks 13 are slidably connected to the inner wall of the assembly tube 1, and a ball head rod 14 is installed at the position of the orientation block 13 corresponding to the directional ring piece 4.

[0024] The following supplementary explanations are made for the technical contents in Embodiment 1 and Embodiment 2: S3: First, when the compressed gas is quickly injected into the built-in tube 7, the kinetic energy of the compressed gas during the filling is used to make the butterfly wings 11 at different positions vibrate irregularly and produce a "vibration feeling". It should be briefly explained that the auxiliary guide rod 10 adopts a hollow tube design, the purpose of which is to expand the "range" of air vibration and improve the "vibration feeling". Because the "vibration feeling" mainly acts on the inside of the built-in tube 7, especially when the repulsive force is "instantly lost" in the left air limiting chamber, the built-in tube 7 quickly impacts the left position and aggravates the gas vibration inside the built-in tube 7, so that the compressed gas has a "vibration feeling" of a certain frequency when it is discharged from the built-in micropores 9, and the solid impurities that may be attached to the opening sleeve 2 are shaken off; S4: combined with S2 for explanation: during the aeration process, the winding electromagnetic coil group 8 and the permanent magnet 5 in the right position mainly generate suction, which can be understood as forcing the built-in tube 7 to slide to the right under the action of suction. However, on the basis of achieving the purpose of instant aeration, under the combined action of suction, repulsion and the pressure generated by the compressed gas, there is an unbalanced mode in which the suction + repulsion is greater than or equal to the pressure generated by the compressed gas. Therefore, in order to complete the "instant aeration" action, the suction and repulsion can be reduced at the same time, or even directly "cancelled", and the built-in tube 7 is forced to move to the right only under the pressure condition generated by the compressed gas; However, in the process of stopping aeration, the specific methods include the following: S4-1: The compressed gas is in a continuous charging state, and the winding electromagnetic coil group 8 and the permanent magnet 5 in the two air limiting chambers both generate suction, such as the left air limiting chamber "forces" the built-in tube 7 to move to the left, and the right air limiting chamber "forces" the built-in tube 7 to move to the right. In order to maintain the stability of the position of the built-in tube 7, the suction forces generated at the two positions are equal, and the suction force at the right position is less than the sum of the pressure generated by the compressed gas and the suction force at the left position; S4-2: Then, when it is necessary to stop the aeration process, it is divided into two stages. In the first stage, the compressed gas filling process is maintained, but the suction force generated at the right position needs to be increased to be slightly greater than or equal to the sum of the pressure generated by the compressed gas and the suction force at the left position, so that the built-in tube 7 shows a "trend" of moving to the right, but the built-in micropores 9 and the open sleeve 2 remain connected. In the second stage, at the same time, the compressed gas filling process is directly stopped, resulting in an instantaneous "loss" of the pressure generated by the compressed gas, and the winding electromagnetic coil group 8 at the left position changes the power supply direction, from suction to repulsion, and then under the synchronous action of suction + repulsion, the built-in tube 7 is forced to move quickly to the right, realizing the separation process between the built-in micropores 9 and the open sleeve 2. The overall process is short. Although the pressure generated by the compressed gas is "instantly lost", the built-in micropores 9 have been stored in the assembly tube 1. S5: Combined with S2 again and refer to Figure 5 It is explained that: in the initial state, the directional ring sheet 4 is always arranged between the winding electromagnetic coil group 8 and the permanent magnet 5. For this, refer to S4-1 and S4-2. When the built-in tube 7 moves to the left or right, the ball head rod 14 therein will first hit the metal ball sleeve 12, so that the ball head rod 14 and the metal ball sleeve 12 can serve as a limiting structure for the built-in tube 7. The directional block 13 for mounting the ball head rod 14 can be further configured as a related structure with sliding friction capability, specifically, the sliding friction process between the directional block 13 and the inner wall of the assembly pipe 1 is used to further cause the assembly pipe 1 to vibrate itself, which will not be described in detail. The key point is: Figure 6 To illustrate, when the ball head rod 14 hits the metal ball sleeve 12, according to the force transmission process, the built-in ball 15 inside the metal ball sleeve 12 is irregularly collided, causing the metal ball sleeve 12 to vibrate significantly, and referring to Figure 5 To explain: the compressed gas will also enter the air limiting chamber, so the "vibration" generated by the metal ball sleeve 12 will also act on the compressed gas inside it, but the key is: it is directly transmitted to the assembly pipe 1 through the metal ring piece 4, and its "vibration" is used to shake off the impurities that may be adsorbed on the outside of the assembly pipe 1.

[0025] In summary: two improvements are made to the conventional aerator in terms of caliber limitation and vibration. The improvements are as follows: the built-in tube is used as the key structure in the aeration process, and the microporous aeration method is still used, but the air outlet structure adopts a large-caliber open sleeve, the purpose is to avoid "excessive" clogging of the micropores by impurities, and the flow process of compressed air in the aeration process is used to specifically realize the linear movement of the built-in tube and the irregular vibration of the butterfly wing applied by the compressed gas, and the suction / repulsion force is applied again during the linear movement of the built-in tube, and the instantaneous aeration action is completed by the balance / imbalance of air pressure and suction / repulsion force, so as to avoid the impurities being sucked into the aerator due to the negative pressure suction generated by the imbalance of air pressure / hydraulic pressure, and the "vibration sense" of the butterfly wing acts on the compressed gas to achieve the cleaning purpose of vibration "removal of impurities".
