Description

Technical Field

[0001] This application relates to the field of sewage treatment. Specifically, it relates to a sewage treatment tank in a sewage treatment plant. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment methods include physical treatment and chemical treatment. In the chemical treatment process, a sewage treatment plant puts chemical agents into the sewage tank.

[0003] A chemical agent input pipeline is installed in the sewage treatment tank to achieve the input of chemical agents into the sewage tank. However, the chemical agent input pipeline is immersed in sewage for a long time and is easily corroded by the sewage, thus reducing the service life of the chemical agent input pipeline. If the chemical agent input pipeline is set above the sewage tank, a sufficient number of pipelines need to be set so that the chemical agents can cover the sewage tank to ensure the sewage treatment efficiency, resulting in an excessive number of pipelines used. For this reason, we propose a sewage treatment tank in a sewage treatment plant. Utility Model Content

[0004] To make up for the above deficiencies, this application provides a sewage treatment tank in a sewage treatment plant, aiming to improve the problem that the chemical agent input pipeline in the existing sewage treatment tank is easily corroded by sewage.

[0008] In a specific implementation scheme, one end of each of several connecting pipes is communicated with an annular sleeve. The inner wall of the annular sleeve is open and sleeved on the connecting pipe. Several through holes are formed on the outer wall of the connecting pipe, and several through holes are communicated with the annular sleeve.

[0009] In a specific embodiment, two limiting plates are fixedly sleeved on the connecting pipe, and the two limiting plates are respectively in contact with the top and bottom of the annular sleeve.

[0010] In a specific embodiment, a plurality of sealing rings are respectively installed on the top and bottom of the annular sleeve, and a plurality of annular sealing grooves are respectively formed on one surface of the two limiting plates, and the sealing rings are arranged in the corresponding annular sealing grooves.

The plurality of transmission rods are in transmission connection with the plurality of connecting pipes, and the motor is in transmission with one of the transmission rods.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0023] Please refer to Figures 1-6 , the present application provides a sewage treatment pool in a sewage treatment plant, including a pool body 10, a bridge 20 is installed on the top of the pool body 10, several spraying mechanisms 30 are rotatably connected to the bottom of the bridge 20, and a driving mechanism 40 and several chemical agent conveying pipelines 50 are also installed at the bottom thereof. The driving mechanism 40 drives several spraying mechanisms 30 to rotate. Several chemical agent conveying pipelines 50 are respectively sleeved on several spraying mechanisms 30 and communicate with the corresponding spraying mechanisms 30. The side walls at both ends of the bridge 20 are stepped. Specifically, the bridge 20 can be used for people to walk on it. At the same time, guardrails are installed on the bridge 20, and stepped shapes are provided at both ends of the bridge 20 to facilitate people to climb onto the bridge 20. The driving mechanism 40 drives several spraying mechanisms 30 to rotate simultaneously to increase the coverage range of the chemical agent. One end of several chemical agent conveying pipelines 50 communicates with the same main pipe, and the main pipe communicates with the existing chemical agent conveying device.

[0024] Refer to Figure 4 , the spraying mechanism 30 includes a connecting pipe 310 rotatably connected to the bottom of the bridge 20. The bottom of the connecting pipe 310 communicates with a hollow plate 320. The bottom of the hollow plate 320 communicates with several nozzles 330. Several chemical agent conveying pipelines 50 are respectively sleeved on several connecting pipes 310. The driving mechanism 40 drives several connecting pipes 310 to rotate. When setting, the connecting pipe 310 rotates, and at the same time drives the hollow plate 320 to rotate. After the chemical agent is conveyed into the connecting pipe 310, it enters the hollow plate 320 and then sprays out from several nozzles 330. At the same time, the sprayed chemical agent can increase the coverage range of the chemical agent on the pool body 10 under the action of centrifugal force.

[0025] Refer to Figure 4, one end of each of several connecting pipes 310 is communicated with an annular sleeve 60. The inner wall of the annular sleeve 60 is open and sleeved on the connecting pipe 310. A plurality of through holes 340 are formed on the outer wall of the connecting pipe 310, and the plurality of through holes 340 are communicated with the annular sleeve 60. When specifically arranged, the connecting pipe 310 rotates in the annular sleeve 60, and at the same time, the through holes 340 are communicated with the annular sleeve 60, so that the chemical agent in the annular sleeve 60 can enter the connecting pipe 310 through the through holes 340.

[0026] Refer to Figure 4 and 6 , two limiting plates 350 are fixedly sleeved on the connecting pipe 310, and the two limiting plates 350 are respectively in contact with the top and bottom of the annular sleeve 60. A plurality of sealing rings 610 are respectively installed on the top and bottom of the annular sleeve 60. A plurality of annular sealing grooves 360 are respectively formed on one surface of the two limiting plates 350, and the sealing rings 610 are arranged in the corresponding annular sealing grooves 360. It should be noted that the two limiting plates 350 achieve the purpose of limiting the annular sleeve 60 and can play a sealing role at the same time. By setting the sealing rings 610 and the annular sealing grooves 360, the contact area between the limiting plate 350 and the annular sleeve 60 can be increased, thereby improving the sealing performance.

[0027] Refer to Figure 3 and 5 , the driving mechanism 40 includes a motor 410 installed at the bottom of the bridge 20 and several transmission rods 420 rotatably connected to the bottom of the bridge 20. The several transmission rods 420 are in transmission connection with the several connecting pipes 310, and the motor 410 is in transmission with one of the transmission rods 420. Specifically, the same transmission belt is sleeved on the several transmission rods 420 and the several connecting pipes 310 to achieve the purpose of synchronously rotating the several connecting pipes 310. Further, an L-shaped plate is installed at the bottom of the bridge 20, and the motor 410 is installed on the L-shaped plate. The driving shaft of the motor 410 is connected with a first bevel gear, and a second bevel gear is sleeved on one of the transmission rods 420. The first bevel gear is engaged with the second bevel gear to drive one of the transmission rods 420.

[0028] When the sewage treatment tank of this sewage treatment plant is in use: sewage is transported into the tank body 10, and then a chemical agent is added into the tank body 10. The chemical agent is transported into the several chemical agent conveying pipes 50 through the existing chemical agent conveying device, so that the chemical agent enters the connecting pipe 310 through the annular sleeve 60, then enters the hollow plate 320 from the connecting pipe 310, and finally sprays the chemical agent downward from the several nozzles 330. During this process, the motor 410 drives one of the transmission rods 420 to rotate, and the transmission rod 420 makes the several connecting pipes 310 rotate synchronously through the transmission belt, so as to make the several hollow plates 320 rotate synchronously to increase the coverage range of the chemical agent.

[0029] It should be noted that the specific model and specifications of the motor 410 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail here.

[0030] The power supply and principle of the motor 410 are clear to those skilled in the art, so they will not be described in detail here.

For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
