Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a wastewater sedimentation reaction structure. Background Technology

[0002] Wastewater settling reaction generally refers to the process in wastewater treatment where suspended solids, particulate matter, or other solid substances in wastewater settle to the bottom using physical or chemical methods. This process mainly utilizes gravity, chemical reactions, or other methods to accelerate the settling of solid substances, thereby achieving the purpose of purifying water quality.

[0003] The existing wastewater settling reaction structure mainly consists of a settling tank and a stirring mechanism installed at the top of the settling tank. When using this wastewater settling reaction structure, the wastewater to be treated and the flocculant are added to the settling tank respectively. Then, under the action of the stirring mechanism, the wastewater and flocculant are fully mixed and reacted, so that the harmful substances in the wastewater are deposited at the bottom of the settling tank through flocculation and sedimentation after the reaction, thereby achieving the removal of harmful substances in the wastewater.

[0004] While existing wastewater settling reaction structures can remove harmful substances from wastewater, they have several drawbacks. First, after mixing wastewater with flocculants, centrifugal force causes the wastewater to rotate around the center of the mixing mechanism, making it difficult for the flocs generated at the end of mixing to settle easily. Second, the assembled precipitates mainly settle by their own weight, which can lead to slow settling speed due to the long settling distance, hindering the rapid settling of flocs in wastewater. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a wastewater sedimentation reaction structure that can both quickly bring stirred wastewater to a static state by obstructing flow and shorten the sedimentation height of flocs, thereby achieving rapid sedimentation of flocs in wastewater.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A wastewater sedimentation reaction structure includes a sedimentation tank. A lifting and flow-blocking mechanism is installed on the upper part of one side wall of the sedimentation tank. A support is installed at the bottom of the sedimentation tank. An auxiliary sedimentation mechanism is installed between the bottom end of the support and the bottom end of the sedimentation tank. The lifting and flow-blocking mechanism includes a motor, a screw, a lifting plate, a bracket, a connecting plate, and a flow-blocking rod. The motor is installed at the middle of the top of the bracket. The screw is connected to the power output end of the motor. The lifting plate is installed on the screw. The connecting plate is installed on one side wall of the lifting plate. The flow-blocking rod is installed at the bottom end of the connecting plate. The auxiliary sedimentation mechanism includes a waterproof electric actuator and a sedimentation screen. The sedimentation screen is located at the bottom end of the sedimentation tank. The telescopic part of the waterproof electric actuator is connected to the middle of the bottom end of the sedimentation screen.

[0008] Optionally, a support plate is installed at the top center of the sedimentation tank, and a stirring mechanism is installed on the support plate. The stirring mechanism includes a motor and a stirring frame.

An auxiliary sedimentation mechanism, consisting of a waterproof electric actuator and sedimentation mesh, is installed at the bottom of the sedimentation tank. During the sedimentation reaction of wastewater, the flow-blocking rod is first inserted into the upper part of the rotating wastewater under the action of the motor, screw, lifting plate, and connecting plate. This increases the resistance to the wastewater's rotation under centrifugal force, allowing the mixed wastewater to quickly settle and facilitating the rapid sedimentation of flocculent matter. After a period of reaction, the sedimentation mesh is raised under the action of the waterproof electric actuator, effectively shortening the settling height of the flocculent matter and thus accelerating the sedimentation rate of the flocculent matter generated after the reaction.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of existing sewage sedimentation reaction structures will first be introduced.

[0024] The existing wastewater settling reaction structure mainly consists of a settling tank and a stirring mechanism installed at the top of the settling tank. When using this wastewater settling reaction structure, the wastewater to be treated and the flocculant are added to the settling tank respectively. Then, under the action of the stirring mechanism, the wastewater and flocculant are fully mixed and reacted, so that the harmful substances in the wastewater are deposited at the bottom of the settling tank through flocculation and sedimentation after the reaction, thereby achieving the removal of harmful substances in the wastewater.

[0025] Please see Figure 1 , Figure 3This application discloses a wastewater sedimentation reaction structure, including a sedimentation tank 3. A lifting and flow-blocking mechanism 7 is installed on the upper part of one side wall of the sedimentation tank 3. A support 4 is installed at the bottom of the sedimentation tank 3. An auxiliary sedimentation mechanism 8 is installed between the bottom of the support 4 and the bottom of the sedimentation tank 3. The lifting and flow-blocking mechanism 7 includes a motor 71, a screw 72, a lifting plate 73, a bracket 74, a connecting plate 75, and a flow-blocking rod 76. The motor 71 is installed at the middle of the top of the bracket 74. The screw 72 is connected to the power output end of the motor 71. The lifting plate 73 is installed on the screw 72. The connecting plate 75 is installed on one side wall of the lifting plate 73. The flow-blocking rod 76 is installed at the bottom of the connecting plate 75. The auxiliary sedimentation mechanism 8 includes a waterproof electric actuator 81 and a sedimentation screen 82. The sedimentation screen 82 is located at the bottom of the sedimentation tank 3. The telescopic part of the waterproof electric actuator 81 is connected to the middle of the bottom of the sedimentation screen 82.

[0026] Specifically, after the wastewater and flocculant in the sedimentation tank 3 are mixed and stirred, the screw 72 is rotated by the motor 71. After the screw 72 rotates, the lifting plate 73 and the connecting plate 75 will move down under the action of the threaded transmission. During the downward movement of the connecting plate 75, the flow-blocking rod 76 is inserted into the wastewater in the sedimentation tank 3. The flow-blocking rod 76 blocks the wastewater, so that the stirred wastewater quickly becomes stable, which facilitates the rapid sedimentation of the flocs generated after the reaction. At the same time, after a period of reaction, the sedimentation screen plate 82 is raised by the action of the waterproof electric actuator 81, which can effectively shorten the settling height of the flocs in the wastewater, thereby making the sedimentation speed of the flocs generated after the reaction in the wastewater faster.

[0027] Please see Figure 1 A support plate 1 is installed at the top center of the sedimentation tank 3. A stirring mechanism 6 is installed on the support plate 1. The stirring mechanism 6 includes a motor 61 and a stirring frame 62.

[0028] As one implementation method, after the motor 61 drives the stirring frame 62 to rotate, the sewage and flocculant in the sedimentation tank 3 will be fully mixed under the action of the stirring frame 62, ensuring that the harmful substances in the sewage are fully flocculated.

[0029] Please see Figure 1 Motor 2 61 is installed at the top center of support plate 1, and stirring rack 62 is connected to the power output end of motor 2 61.

[0030] As one implementation method, the support plate 1 provides a stable mounting base for the second motor 61, and connecting the stirring frame 62 to the power output end of the second motor 61 can ensure convenient rotation and adjustment of the stirring frame 62 under the action of the second motor 61.

[0031] Please see Figures 1-2 A cleaning pump 5 is installed on the lower part of one side wall of the sedimentation tank 3, and a drainage pump 2 is installed on the upper part of the other side wall of the sedimentation tank 3.

[0032] As one implementation method, the cleaning pump 5 is mainly used to conveniently discharge the flocculent material that has settled in the sedimentation tank 3, while the drainage pump 2 is mainly used to conveniently discharge the supernatant in the sewage after settling.

[0033] Please see Figure 1 The screw 72 passes through the lifting plate 73 and is threadedly connected to the lifting plate 73. The lifting plate 73 is slidably engaged with the bracket 74.

[0034] As one implementation method, the screw 72 is threadedly connected to the lifting plate 73, which allows the lifting plate 73 to be easily raised and lowered after the screw 72 rotates. The sliding fit installation method makes the lifting plate 73 more stable in its adjustment relative to the bracket 74.

[0035] Please see Figure 1 There are two connecting plates 75, and the two connecting plates 75 are symmetrically installed on the lifting plate 73.

[0036] In one implementation, the connecting plate 75 is mainly used to provide an installation base for the flow-blocking rod 76, and at the same time can ensure that the flow-blocking rod 76 is adjusted synchronously with the lifting plate 73.

[0037] Please see Figures 1-2 The flow-blocking rod 76 is welded to the connecting plate 75, and the bracket 74 is bolted to the sedimentation tank 3.

[0038] As one implementation method, the welding installation method makes the connection between the flow-blocking rod 76 and the connecting plate 75 more secure, and the bolt connection method makes the installation of the bracket 74 on the sedimentation tank 3 more stable.

[0039] Please see Figures 1-2 The fixed part of the waterproof electric actuator 81 is bolted to the support 4, the telescopic part of the waterproof electric actuator 81 is slidably sealed to the support 4 and the bottom of the sedimentation tank 3, and the telescopic part of the waterproof electric actuator 81 is bolted to the sedimentation mesh plate 82.

[0040] As one implementation method, the support 4 can provide an installation base for the waterproof electric actuator 81. The sliding seal connection method can ensure that the waterproof electric actuator 81 can be easily raised and lowered to the sedimentation screen plate 82, while preventing sewage in the sedimentation tank 3 from leaking out through the waterproof electric actuator 81.

[0041] Please see Figures 1-2 The sedimentation screen plate 82 has a groove reserved on the sludge suction pipe that is attached to the cleaning pump 5.

[0042] As one implementation method, the groove design makes it easier for the sedimentation screen plate 82 to slide relative to the built-in suction pipe on the cleaning pump 5.

[0043] The specific working principle is as follows: When treating wastewater through sedimentation reaction, wastewater and flocculant are first added to sedimentation tank 3. Then, as motor 2 61 drives the stirring frame 62 to rotate, the wastewater and flocculant are quickly mixed. After mixing, motor 1 71 causes screw 72 to rotate. After screw 72 rotates, the lifting plate 73 and connecting plate 75 move down under the action of threaded transmission. During the downward movement of connecting plate 75, the flow-blocking rod 76 is inserted into the wastewater in sedimentation tank 3. Through the flow-blocking effect of the flow-blocking rod 76, the stirred wastewater quickly becomes stable, which facilitates the rapid sedimentation of the flocculants generated after the reaction. At the same time, after a period of reaction, the sedimentation screen plate 82 is raised under the action of waterproof electric push rod 81, which can effectively shorten the sedimentation height of flocculants in wastewater, thereby making the sedimentation speed of flocculants generated after the reaction in wastewater faster.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
