Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a hydrogen peroxide sewage pretreatment device. Background Art

[0002] In the process of hydrogen peroxide production, wastewater containing hydrogen peroxide and other organic substances will be generated. These wastewaters need to be treated before being discharged or reused. During the treatment process, a reaction solution is first added to precipitate the particulate matter in the wastewater to remove suspended solids and other harmful substances in the wastewater.

[0003] To accelerate the reaction rate between the wastewater and the reaction solution, stirring is usually used for treatment. However, the generated precipitate will move with the stirring and will not precipitate at the bottom of the reaction kettle, and the precipitation treatment operation can only be carried out after standing still. Summary of the Utility Model

[0004] In view of the problem that the generated precipitate in the prior art moves with the stirring and is not convenient for treatment, the utility model proposes the following technical solutions:

[0005] A hydrogen peroxide sewage pretreatment device, comprising: a reaction kettle and a discharge pipe. The top of the discharge pipe is communicated with the bottom of the reaction kettle. A liquid inlet pipe and a feed pipe are arranged at the top of the reaction kettle. A moving ring is movably inserted into the discharge pipe and is hermetically arranged on the inner wall surface of the discharge pipe. An isolation net is arranged inside the moving ring. A cylinder is arranged at the bottom of the discharge pipe, and the moving ring is fixedly connected to the output end of the cylinder.

[0006] Preferably, as the above technical solution, a sealing plug is arranged at the bottom of the moving ring, a connecting plate is arranged at the bottom of the sealing plug, and the connecting plate is fixedly connected to the inner wall of the discharge pipe.

[0007] Preferably, as the above technical solution, a telescopic pipe is fixedly connected between the moving ring and the inner wall of the discharge pipe, and the telescopic pipe is sleeved on the surface of the cylinder connecting rod.

[0008] Preferably, as the above technical solution, a motor is arranged at the top of the reaction kettle, a stirring frame is rotatably inserted into the reaction kettle, and the stirring frame is fixedly connected to the output end of the motor.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. By moving the moving ring, the vortex-shaped rotating precipitate is moved from the top of the discharge pipe to the bottom. The precipitate will not continue to rotate with the sewage. After filtering out the liquid by using the isolation net, the precipitate is collected in the discharge pipe, which is convenient for treating the precipitate;

[0011] 2. The movable isolation net can extrude the sediment to drain the water in the sediment. After the sealing plug enters the bottom of the movable ring, it closes the discharge pipe, thus isolating the bottom of the discharge pipe from the sewage above, facilitating the opening of the bottom of the discharge pipe to process the compressed and dehydrated sediment.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings of the description.

[0017] Embodiment

[0018] Figures 1-3 In the hydrogen peroxide sewage pretreatment device, it includes: a reaction kettle 10 and a discharge pipe 20. The top of the discharge pipe 20 is connected to the bottom of the reaction kettle 10 in a communicating manner. The top of the reaction kettle 10 is provided with a liquid inlet pipe 11 and a feed pipe 12. It is characterized in that a movable ring 31 is movably inserted inside the discharge pipe 20 and is hermetically arranged on the inner wall surface of the discharge pipe 20. An isolation net 32 is arranged inside the movable ring 31. A cylinder 33 is arranged at the bottom of the discharge pipe 20. The movable ring 31 is fixedly connected to the output end of the cylinder 33.

[0019] When it is necessary to treat hydrogen peroxide sewage, it is injected into the reaction kettle 10 through the liquid inlet pipe 11. Subsequently, a reaction solution is added from the feed pipe 12 and stirred. During the stirring process, the generated sediment rotates in a vortex shape at the bottom of the discharge pipe 20. Subsequently, the cylinder 33 is started to move the movable ring 31 through a connecting rod. The movable ring 31 gradually moves downward and moves the vortex-shaped rotating sediment from the top to the bottom of the discharge pipe 20. Since the isolation net 32 is arranged inside the movable ring 31, the liquid leaves through the isolation net 32 and isolates the sediment, thereby treating the sediment.

[0020] By moving the moving ring 31, the precipitates rotating in a vortex shape are moved from the top to the bottom of the discharge pipe 20. The precipitates will not continue to rotate with the sewage. After filtering out the liquid by using the isolation net 32, the precipitates are collected in the discharge pipe 20, which facilitates the treatment of the precipitates.

[0021] Figures 2-3 In [description], a sealing plug 34 is arranged at the bottom of the moving ring 31, a connecting plate 35 is arranged at the bottom of the sealing plug 34, and the connecting plate 35 is fixedly connected to the inner wall of the discharge pipe 20.

[0022] During the movement of the moving ring 31, the isolation net 32 squeezes the precipitates to drain the water in the precipitates. When the sealing plug 34 enters the bottom of the moving ring 31, the moving ring 31 and the sealing plug 34 seal the bottom of the discharge pipe 20, thus facilitating the opening of the bottom of the discharge pipe 20 to treat the precipitates.

[0023] The moving isolation net 32 can squeeze the precipitates to drain the water in the precipitates, and after the sealing plug 34 enters the bottom of the moving ring 31, the discharge pipe 20 is sealed, thereby isolating the bottom of the discharge pipe 20 from the sewage above, which facilitates the opening of the bottom of the discharge pipe 20 to treat the compressed and dehydrated precipitates.

[0024] Figures 2-3 In [description], a telescopic pipe 36 is fixedly connected between the moving ring 31 and the inner wall of the discharge pipe 20, and the telescopic pipe 36 is sleeved on the surface of the connecting rod of the air cylinder 33.

[0025] The telescopic pipe 36 can extend or contract as the moving ring 31 moves. By using the deformation of the telescopic pipe 36, the moving path of the connecting rod of the air cylinder 33 is sealed to prevent sewage from flowing out of the bottom of the discharge pipe 20.

[0026] Figure 2 In [description], a motor 40 is arranged at the top of the reaction kettle 10, a stirring frame 50 is rotatably inserted into the reaction kettle 10, and the stirring frame 50 is fixedly connected to the output end of the motor 40.

[0027] When the motor 40 works, it drives the stirring frame 50 to rotate. The stirring frame 50 rotates rapidly to stir the sewage so that it is quickly mixed with the reaction solution. At the same time, due to the stirring of the stirring frame 50, the precipitates generate a vortex-like rotation in the discharge pipe 20, thus facilitating the subsequent treatment of the precipitates.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
