Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a precise aeration control system for a sewage plant. Background Art

[0002] Aeration refers to the process of forcibly transferring oxygen from the air to the liquid, with the purpose of obtaining sufficient dissolved oxygen. In addition, aeration also prevents the suspended matter in the pool from sinking and strengthens the contact between the organic matter in the pool and the microorganisms and dissolved oxygen. This ensures that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen.

[0003] Usually, the biochemical pool in the sewage treatment plant needs to be aerated to ensure that there is sufficient dissolved oxygen inside the biochemical pool. During the aeration process, the staff needs to cooperate with the aeration control structure to adaptively adjust the aeration volume. At present, the aeration control mechanism is often manually adjusted by the relevant staff based on experience. For those who lack experience, it is difficult to ensure accurate control of the aeration volume, and it lacks a certain convenience. Utility Model Content

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, the utility model provides an aeration precision control system for a sewage treatment plant, comprising: an aeration tank 1, a main air supply pipe 2, a branch air supply pipe 3, an aeration pipe 4 and a sealing sleeve 5. The aeration tank 1 is in a square structure as a whole, and an aeration tank 11 is arranged in the aeration tank 1; the main air supply pipe 2 is arranged close to both ends of the bottom of the aeration tank 11, and a plurality of branch air supply pipes 3 are evenly arranged on the side of the main air supply pipe 2, and an aeration pipe 4 is vertically installed on each branch air supply pipe 3; aeration holes 41 are arranged on the surface of the aeration pipe 4, the sealing sleeve 5 has an opening at the bottom, and the sealing sleeve 5 is fitted on the aeration pipe 4 through the lower opening; an electric push rod is arranged on the top of the aeration pipe 4, the sealing sleeve 5 is connected to the output end of the electric push rod, and the electric push rod is connected to a controller.

[0019] Among them, an air inlet pipe 21 is arranged in the middle of the main air supply pipe 2, an air inlet 15 is arranged on the wall of the aeration tank 11, and the air inlet pipe 21 and the air inlet 15 are connected to each other; an accessory box 12 is arranged outside the aeration tank 1. The accessory box 12 is used to store accessories for generating gas, and gas is supplied to the air inlet pipe 21 through the air inlet 15, so that the main air supply pipe 2 can supply gas to the branch air supply pipe 3 and the aeration pipe 4 for aeration work.

[0020] Among them, a sealing head 31 is provided at one end of the branch air supply pipe 3 away from the main air supply pipe 2, and the aeration holes 41 are set as circular through holes. The aeration holes 41 are arranged in a circular array at the same height of the aeration pipe 4, and are arranged in a rectangular array along the length direction of the aeration pipe 4. The sealing head 31 can block the branch air supply pipe 3 to allow the gas to flow to the aeration pipe 4 and flow out from the aeration holes 41; the circular through hole-shaped aeration holes 41 are convenient for the discharge of gas, and the evenly arranged aeration holes 41 have a higher aeration efficiency. By changing the height of the sealing sleeve 5, the upper aeration holes 41 are covered, thereby adjusting the aeration efficiency.

[0021] Among them, an annular guide seat 51 is arranged at the top of the sealing sleeve 5, and a guide rod 42 is arranged at the top of the aeration tube 4. The guide rod 42 passes through the guide seat 51 in cooperation, and the guide rod 42 and the electric push rod at the top of the aeration tube 4 are arranged staggered with each other. The guide seat 51 is arranged on the guide rod 42, which can support the movement of the sealing sleeve 5, limit its moving direction, and prevent it from deflecting during the movement.

[0022] A limit block 43 is disposed at the top of the guide rod 42, and the limit block 43 is mutually locked with the guide seat 51. The setting of the limit block 43 prevents the sealing sleeve 5 from being separated from the guide rod 42.

[0023] Among them, a support base 13 is provided at the bottom of the aeration tank 11. The support base 13 is correspondingly arranged below the branch air supply pipe 3, and a U-shaped card slot 14 is provided on the support base 13, and the branch air supply pipe 3 is fitted and clamped in the card slot 14; not less than three groups of support bases 13 are provided at the lower part of each branch air supply pipe 3. Due to the working nature of the main air supply pipe 2 and the branch air supply pipe 3, they have different diameters. The diameter of the main air supply pipe 2 is larger than that of the branch air supply pipe 3. Therefore, when the main air supply pipe 2 is placed in the aeration tank 11, the bottom of the branch air supply pipe 3 is most likely in a suspended state during setting; therefore, the support base 13 is provided for support to play a role of support and protection, and the branch air supply pipe 3 is clamped by the U-shaped card slot 14 to prevent it from shifting.
