Description

Technical Field

[0001] The utility model relates to the technical field of an aerator height adjustment device for sewage treatment. Background Technique

[0002] Aeration refers to the process of forcibly transferring oxygen in the air into the liquid. Its purpose is to obtain sufficient dissolved oxygen. In addition, aeration also aims to prevent the suspension in the pool from sinking and strengthen the contact between the organic matter, microorganisms and dissolved oxygen in the pool, so as to ensure that the microorganisms in the pool oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. According to different principles and uses, submersible aerators can be divided into two types: submersible jet aerators and submersible centrifugal aerators. Submersible aerators are used for aeration and agitation in the aeration tank and aerated grit chamber of sewage treatment plants, oxygenation and mixing of the mixed liquid of sewage sludge, biochemical treatment of sewage, aquaculture oxygenation and landscape water maintenance.

[0003] The structure of the aeration system is simple, and the aeration height cannot be adjusted. Especially for the aeration operation by submersible aerators, the height of the aeration distance from the liquid surface is also judged only by the experience of the operators, which causes difficulties for the automation transformation and intelligent transformation of old equipment. In order to achieve low-cost transformation and cooperate with old equipment to improve the automation and intelligent levels of the system, this application is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an aeration stirring lifting and adjusting device to solve the problems put forward in the above background technique.

A winch mechanism is installed on the bracket, and a tensioning wheel is fixed at the bottom of the pool. The submersible aerator is installed between the winch mechanism and the tensioning wheel through a steel wire. The winch mechanism rotates to drive the steel wire to transmit and adjust the height of the submersible aerator.

[0007] As a further scheme of the utility model: The steel wire is installed between the submersible aerator through a connector;

Detailed implementation mode

[0022] Please refer to Figures 1 to 4 In the embodiment of the present utility model, an aeration stirring lifting and adjusting device includes a bracket 1 and a submersible aerator 6. A winch mechanism 2 is installed on the bracket 1, and a tensioning wheel 3 is fixed at the bottom of the pool. A submersible aerator 6 is installed between the winch mechanism 2 and the tensioning wheel 3 through a steel wire 4. The rotation of the winch mechanism 2 drives the transmission of the steel wire 4 to adjust the height of the submersible aerator 6. By rotating and stopping the winch mechanism 2, the steel wire 4 is conveyed to move cyclically. The submersible aerator 6 is fixed on the steel wire 4. While the winch mechanism 2 rotates, the submersible aerator 6 moves up and down accordingly to adjust the height, achieving the height adjustment effect of the submersible aerator 6.

[0023] In a preferred implementation mode, the steel wire 4 and the submersible aerator 6 are installed through a connector 5;

[0024] The connector 5 includes a connection body 501, a sleeve part 502, a fixing plate 503 and a clamping plate 504. The sleeve part 502 and the fixing plate 503 are respectively installed on both sides of the connection body 501. The fixing plate 503 installs the clamping plate 504 through bolts. The two ends of the steel wire 4 are connected end to end and tightened by the winch mechanism 2 and the tensioning wheel 3. The fixing plate 503 and the clamping plate 504 are clamped and fixed on the steel wire 4 through bolts. The sleeve part 502 is located outside the steel wire 4 on the other side and can slide outside the steel wire 4. The steel wire 4 is connected end to end to form a closed loop. Under the tensioning action of the winch mechanism 2 and the tensioning wheel 3, the steel wire 4 is tensioned and straightened. The sleeve part 502 slides on the steel wire, and the fixing plate 503 is fixed to the steel wire 4. Under the installation action of the sleeve part 502 and the fixing plate 503 on the steel wire 4, a limit is formed on the submersible aerator 6, so that the submersible aerator 6 maintains a certain angle for aeration operation.

[0025] In a preferred implementation mode, an aerator mounting seat 505 is provided on one side of the clamping plate 504, and the submersible aerator 6 is fixed on the aerator mounting seat 505 through bolts.

[0026] In a preferred implementation mode, the winch mechanism 2 includes a wire frame 201, a wire wheel 202, a worm gear 204, a worm 205 and a hand crank 206. A rotatable wire wheel 202 is arranged inside the wire frame 201. A worm gear 204 that rotates together is fixed on one side of the wire wheel 202. A worm 205 that meshes with the worm gear 204 is installed on the wire frame 201. A hand crank 206 is installed at one end of the worm 205. The winch mechanism 2 has two driving methods for selection according to needs. The hand crank 206 is a manual driving method. Replace the hand crank 206 with a stepping motor, and the worm 205 is rotated by the stepping motor without manual driving.

[0027] In a preferred embodiment, a protective housing 203 located outside the worm gear 204 and the worm 205 is installed on the wire rack 201. The worm 205 penetrates through the protective housing 203 and extends to the outside. The worm gear 204 and the worm 205 are driven by meshing. Therefore, the installation of the protective housing 203 prevents foreign objects from entering the teeth or rusting.

[0028] In a preferred embodiment, the outside of the worm 205 is fixedly connected to the wire rack 201 through a bearing 209. An encoder 207 is also installed on the wire wheel 202. The encoder 207 is configured with a display 208. By recording the number of rotations of the wire wheel 202, the height of the submersible aerator 6 can be calculated, and the value can be displayed through the display 208. In cooperation with the use of the terminal and the stepping motor, the adjustment of the aeration height can be controlled through the system and remotely.

[0029] It should be noted that the above embodiments all belong to the same inventive concept of the utility model. The descriptions of the embodiments have their own emphases. For the parts not described in detail in individual embodiments, reference can be made to the descriptions in other embodiments.
