Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to an aeration device for wastewater treatment ponds. Background Technology

[0002] In the wastewater treatment process, air is forcibly introduced into the wastewater through aeration devices, allowing the wastewater in the pool to come into contact with the air and be oxygenated, thus achieving aeration. The principle is that the organic pollutants in the wastewater mainly rely on aerobic microorganisms for degradation. Aeration introduces air into the wastewater through mechanical or natural means, increasing the oxygen content in the water body to ensure that microorganisms can reproduce healthily in an aerobic environment.

[0003] When aeration devices are used in sewage treatment ponds, their aeration heads are generally located at the bottom of the pond and always facing upwards. When the device is stopped, dirt in the sewage may fall into the aeration heads, causing them to become clogged and affecting subsequent use. Utility Model Content

[0004] This invention addresses the technical problem that dirt and grime in wastewater can enter the aeration heads and cause blockages when the system is shut down, by providing an aeration device for wastewater treatment ponds.

[0007] In this technical solution, the protective mechanism is driven to rotate by the drive mechanism, so that the protective mechanism can switch between a horizontal state and a non-horizontal state. After the aeration component stops, the protective mechanism is adjusted to a horizontal state, which can cover the top outlet of the aeration head to protect it and prevent dirt from entering. During normal aeration, the protective mechanism is adjusted to a vertical state, that is, a non-horizontal state, so as not to block the aeration head.

[0008] Preferably, the aeration assembly includes an aerator and a horizontal pipe laid on the inner wall of the bottom of the sewage treatment tank; the aerator is fixedly installed on one side of the sewage treatment tank, and the output port of the aerator is connected to a delivery pipe, the delivery pipe is connected to a diversion pipe, the diversion pipe is connected to the horizontal pipe, and the horizontal pipe is connected to the aeration head.

The input end of the transmission part is connected to a rocker arm, and the output end of the transmission part is connected to one end of a flipping rod.

[0013] Preferably, the transmission part includes a rotating shaft and a worm gear, both of which are rotatably mounted in the protective box. A worm wheel is fixedly sleeved on the rotating shaft, and the worm wheel meshes with the worm gear. One end of the rotating shaft is fixedly connected to the end of the flipping rod, and one end of the rocker arm is fixedly connected to one end of the worm gear.

[0014] Preferably, the rocker arm is rotatably mounted to one side of the protective box, and a plastic sleeve is fixedly fitted onto the rocker arm.

[0015] In this technical solution, a drive mechanism is used to drive the protective mechanism to rotate, adjust the position of the baffle, so that the baffle covers the aeration head or removes the obstruction of the aeration head.

[0016] Preferably, the cleaning mechanism includes a plurality of scraper sleeves, which are slidably fitted onto a plurality of baffles, and the scraper sleeves are connected to a linear drive assembly.

[0017] Preferably, a connecting frame is fixedly installed between each pair of adjacent scraper sleeves, and a scraper blade is provided on the inner bottom side of the scraper sleeve, the scraper blade abutting against the bottom surface of the baffle.

[0023] The aforementioned aeration device for wastewater treatment ponds, by incorporating a reversible and adjustable protective mechanism and a drive mechanism that powers the protective mechanism, ensures that under normal aeration conditions, the protective mechanism does not contact the top outlet of the aeration head, thus not affecting the use of the aeration head. When the system is off, the drive mechanism rotates the protective mechanism to a horizontal position, covering the top outlet of the aeration head with its bottom surface, preventing contaminants from entering the wastewater and thus preventing blockages. Furthermore, a cleaning mechanism is installed on the protective mechanism to scrape off any contaminants adhering to its bottom surface, preventing the protective mechanism from further obstructing the aeration head.

[0037] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0038] like Figure 1-7 As shown, the aeration device for the wastewater treatment tank includes a wastewater treatment tank 1; it also includes:

[0039] Aeration component 2 is installed in the sewage treatment tank 1. The aeration component 2 is provided with a plurality of aeration heads 205 evenly distributed to the bottom of the sewage treatment tank 1, and the top of the aeration head 205 is provided with an outlet.

[0040] The protective mechanism 3 is rotatably installed inside the sewage treatment tank 1, and the bottom surface of the protective mechanism 3 covers the outlet of the aeration head 205.

[0041] Drive mechanism 4 provides rotation drive for protective mechanism 3, enabling protective mechanism 3 to switch between horizontal and non-horizontal states;

[0042] Cleaning mechanism 5 is mounted on protective mechanism 3.

[0043] like Figure 3 and 6 As shown, as a specific technical solution, the aeration component 2 includes an aerator 201 and a horizontal pipe 204 laid on the inner wall of the bottom of the sewage treatment tank 1; the aerator 201 is fixedly installed on one side of the sewage treatment tank 1, and the output port of the aerator 201 is connected to a conveying pipe 202, the conveying pipe 202 is connected to a diversion pipe 203, the diversion pipe 203 is connected to the horizontal pipe 204, and the horizontal pipe 204 is connected to the aeration head 205.

[0044] The conveying pipe 202 penetrates the side wall of the sewage treatment tank 1, extending into the sewage treatment tank 1 and connecting with the diversion pipe 203 inside the sewage treatment tank 1. Both ends of the diversion pipe 203 are sealed, and a portion of the diversion pipe 203 along its length is connected to multiple horizontal pipes 204. The end of the horizontal pipe 204 away from the diversion pipe 203 is closed, and several aeration heads 205 are evenly distributed and installed on multiple horizontal pipes 204.

[0045] When aerating the sewage in sewage treatment pond 1, the gas generated by aerator 201 passes through conveying pipe 202, diversion pipe 203 and horizontal pipe 204 in sequence, and is then sprayed out through the top outlet of aeration head 205 into the sewage to aerate it; after aeration, aerator 201 is turned off.

[0046] In the above, when aeration is performed, the protective mechanism 3 is in a vertical state, that is, the baffle 302 in the protective mechanism 3 is vertical and the baffle 302 does not block the outlet of the aeration head 205.

[0047] like Figure 4 and Figure 6 As shown, as a specific technical solution, the protective mechanism 3 includes a flipping rod 301; the flipping rod 301 is rotatably installed inside one side of the sewage treatment tank 1, and multiple baffles 302 are fixedly connected to the flipping rod 301 at equal intervals.

[0048] like Figure 2 As shown, as a specific technical solution, the drive mechanism 4 includes a protective box 401; the protective box 401 is fixedly installed on the outer wall of the sewage treatment tank 1, and a transmission part is provided inside the protective box 401. The input end of the transmission part is connected to a rocker arm 405, and the output end of the transmission part is connected to one end of the flipping rod 301.

[0049] The transmission unit includes a rotating shaft 402 and a worm gear 403. Both the rotating shaft 402 and the worm gear 403 are rotatably mounted in the protective box 401. A worm wheel 404 is fixedly sleeved on the rotating shaft 402. The worm wheel 404 meshes with the worm gear 403. One end of the rotating shaft 402 is fixedly connected to the end of the flipping rod 301, and one end of the rocker arm 405 is fixedly connected to one end of the worm gear 403.

[0050] The rocker arm 405 is rotatably mounted to one side of the protective box 401, and a plastic sleeve is fixedly fitted onto the rocker arm 405. The plastic sleeve is for the user's hand to grip.

[0051] After the aerator 201 is turned off, the top outlet of the aerator head 205 stops emitting air, which can lead to dirt entering. To prevent dirt from entering, the drive mechanism 4 is used to adjust the protective mechanism 3 to a horizontal position, causing the baffle 302 to cover the top outlet of the aerator head 205. Figure 6 As shown.

[0052] The specific operation is as follows: by shaking the rocker arm 405, the worm gear 403 is rotated. Through the meshing of the worm gear 403 and the worm wheel 404, the rotating shaft 402 is rotated. The rotating shaft 402 drives the flipping rod 301 to rotate. The baffle 302 on the flipping rod 301 rotates together, so that the baffle 302 is adjusted to a horizontal state. The baffle 302 blocks and seals the outlet at the top of the aeration head 205 to prevent dirt from entering.

[0053] Before the next aeration, by rotating the rocker arm 405 in the opposite direction, the transmission unit drives the flipping rod 301 to rotate the baffle 302, adjusting the baffle 302 to be vertical, so that the baffle 302 does not block the top outlet of the aeration head 205.

[0054] It should be noted that the top outlets of several aeration heads 205 are aligned and at the same height. When the baffle 302 is adjusted to be horizontal, the top surface of the aeration head 205 is exactly in contact with the baffle 302.

[0055] like Figure 4-7 As shown, as a specific technical solution, the cleaning mechanism 5 includes a scraper sleeve 505, and the number of scraper sleeves 505 is multiple, and the multiple scraper sleeves 505 are respectively slidably sleeved on multiple baffles 302, and the scraper sleeves 505 are connected to a linear drive assembly.

[0056] A connecting bracket 506 is fixedly installed between each pair of adjacent scraper sleeves 505, and a scraper blade 5051 is provided on the inner bottom side of the scraper sleeve 505, the scraper blade 5051 abutting against the bottom surface of the stop bar 302.

[0057] The linear drive assembly includes a screw 501, with end brackets 502 rotatably mounted at both ends of the screw 501. The end brackets 502 are fixedly mounted on the top surface of the stop bar 302. A nut seat 504 is threadedly connected to the screw 501, and the nut seat 504 is fixedly connected to the scraper sleeve 505.

[0058] The screw 501 is parallel to the stop bar 302, and a grip 503 is fixedly connected to the end of the screw 501 away from the flip bar 301. The grip 503 has anti-slip texture on its circumferential surface.

[0059] Without covering the top opening of the aeration head 205, part of the baffle 302 is located inside the sewage treatment tank 1, and dirt from the sewage may adhere to it.

[0060] If the bottom surface of the baffle 302 is dirty, the cleaning mechanism 5 is used to clean the bottom surface of the baffle 302 to keep the bottom surface of the baffle 302 clean and prevent the bottom surface of the baffle 302 from sticking to the top surface of the aeration head 205 when it is dirty, so that the dirt on it can enter the aeration head 205.

[0061] The specific cleaning of the baffle 302 is as follows: The protective mechanism 3 is rotated by the drive mechanism 4, causing the baffle 302 to flip and move to a state between vertical and horizontal, i.e., the baffle 302 has an angle of less than 90° with the horizontal, and the end of the baffle 302 away from the flipping rod 301 just moves to the top of the sewage treatment tank 1. Adjusting it to this state prevents the end of the baffle 302 from being adjusted too high, facilitating manual gripping of the handle 503. Next, rotating the handle 503 causes the screw 501 to rotate, and the screw 501 screws into the nut seat 504, driving the nut seat 504 and the scraper sleeve 505 to move together. Initially, the scraper sleeve 505 is in the position shown in the image. Figure 6-7 In the state shown, by driving the scraper sleeve 505 to move, the scraper sleeve 505 moves towards the end of the baffle 302 away from the flipping rod 301, and the dirt on the baffle 302 is scraped off by the scraper blade 5051 to achieve cleaning.

[0062] After cleaning, reverse the rotation of the handle 503 to return the scraper sleeve 505 to its original position. Figure 6-7 The state shown.

[0063] During the cleaning of the bottom surface of the baffle 302, one worker operates the handle 503, while another worker uses a tool to catch the dirt that falls from the bottom surface of the baffle 302 during cleaning. The tool can be a basin.

The protection scope of this utility model is defined by the appended claims.
