There are many ways to treat sewage, and reaction sedimentation is one of them, which requires the use of a reaction tank for operation.

[0003] In the prior art, the existing sewage treatment reaction tank directly enters the reaction tank through a sewage pipe, and then the electrolytic reaction plate inside the result realizes electrolytic treatment, but the sewage is directly discharged, and there is no specific waterway designed inside the reaction tank, resulting in the sewage flowing too fast and the contact area and time with the electrolytic reaction plate are insufficient, resulting in poor sewage treatment effect; at the same time, in general sewage treatment, it is necessary to make the flocculant and sewage fully mixed and react, and precipitation will be produced after the use of the flocculant, but there is no corresponding sludge discharge structure, which makes cleaning very troublesome and greatly reduces work efficiency.

DETAILED DESCRIPTION

[0025] See also Figure 1-6 As shown, the utility model relates to a sewage treatment reaction tank, including a reaction tank box body 1, the reaction tank box body 1 is connected to a sewage inlet pipe 11 and a sewage outlet pipe 12, a top cover 2 is arranged at an opening position on the surface of the reaction tank box body 1, the top cover 2 is provided with an exhaust pipe 21, and handles 22 are arranged on both sides for convenient opening of the top cover 2; at the same time, an observation window 23 is arranged on the top cover 2, which is opened and closed by a push-pull plate 24, and the observation window 23 can facilitate the later sampling and detection of sewage.

[0026] The exhaust pipe 21 provided on the top cover 2 helps to discharge the gas generated during the reaction process, avoids the accumulation of gas inside the reaction tank, and ensures the safety of operation. The handles 22 on both sides are designed so that the operator can easily lift it when the top cover 2 needs to be opened, which improves the convenience of operation. The observation window 23 provided on the top cover 2 is opened and closed by pushing and pulling, which not only ensures the sealing of the reaction tank, but also facilitates the operator to observe the situation inside the reaction tank without opening the top cover 2, and at the same time facilitates the sampling and testing of sewage, thereby enhancing the practicality of the equipment.

[0027] See also Figure 2As shown, a plurality of reaction zones 10 arranged in sequence and connected are arranged in the reaction tank box 1, and a plurality of electrode plates 3 are arranged in each reaction zone 10, wherein a sewage inlet 105 is arranged at the bottom of each reaction zone 10, for the sewage to pass through the plurality of electrode plates 3 from bottom to top for electrolysis, and a sewage outlet 1022 is arranged on one side of the top of the reaction zone 10, and the sewage outlet 1022 is a transverse tooth-shaped opening, which can realize a more uniform overflow of sewage and control the overflow speed. (For the specific waterway direction, please refer to Figure 2 ).

[0028] The design of multiple reaction zones 10 arranged in sequence and connected allows sewage to pass through multiple reaction zones 10 in sequence, thereby increasing the contact time and area between sewage and electrode plates 3, which helps to improve the efficiency of electrolytic treatment. Each reaction zone 10 can be independently designed according to treatment requirements, such as volume, shape, etc., to adapt to different treatment processes. Several electrode plates 3 are arranged in each reaction zone 10 to achieve electrolytic treatment of sewage. The number and arrangement of electrode plates 3 can be adjusted according to the size of the reaction zone 10 and the treatment requirements to optimize the electrolytic effect.

[0029] The sewage inlet 105 provided at the bottom of each reaction zone 10 enables the sewage to pass through the multiple electrode plates 3 from bottom to top for electrolytic treatment. This design helps to ensure sufficient contact between the sewage and the electrode plates 3, thereby improving the electrolysis efficiency. The transverse toothed sewage outlet 1022 provided on one side of the top of the reaction zone 10 can achieve uniform overflow of the sewage and control the overflow speed. This design helps to prevent the sewage from accumulating or flowing out too quickly in the reaction zone 10, thereby ensuring that the sewage is fully treated in the reaction zone 10. At the same time, the toothed opening structure can also increase the area of ​​the outlet, reduce the resistance of the sewage flow, and improve the water discharge efficiency.

[0030] The reaction zone 10 includes a first partition 101 and a second partition 102, both of which are horizontally placed in the reaction tank, and the two ends of the first partition 101 and the second partition 102 are respectively fixed to the inner walls of the two sides of the reaction tank, and the surface of the first partition 101 is provided with a plurality of equally spaced positioning protrusions 31, and adjacent positioning protrusions 31 form a positioning position extending in the vertical direction. Users can set multiple electrode plates 3 at different positioning positions according to actual needs, and then adjust the spacing between multiple electrode plates 3. In addition, a supporting plate 106 is provided at the bottom to support the bottom of the electrode plate 3.

[0031] The reaction zone 10 is effectively separated by the first partition 101 and the second partition 102 placed horizontally in the reaction tank, ensuring that the sewage can be fully treated in each reaction zone 10. The setting of the partition also helps to maintain the water flow state in the reaction zone 10 and promote the uniform progress of the electrolysis reaction. The two ends of the partition are fixed to the inner walls of the reaction tank on both sides. This design enhances the stability of the partition, prevents it from displacement or deformation during the treatment process, and ensures the stable operation of the reaction zone 10. Several equidistant positioning protrusions 31 set on the first partition 101 and the second partition 102 provide users with a basis for flexibly adjusting the position of the electrode plate 3. The equidistant design of the positioning protrusions 31 ensures that the spacing between the electrode plates 3 is uniform, which is conducive to the uniform progress of the electrolysis reaction. Adjacent positioning protrusions 31 constitute a positioning card extending in the vertical direction, and users can place the electrode plate 3 on different positioning cards according to actual needs. This design makes it simple and convenient to adjust the spacing of the electrode plate 3, and improves the adaptability and flexibility of the equipment.

[0032] Function of the support plate 106: The support plate 106 disposed at the bottom of the reaction zone 10 is used to support the bottom of the electrode plate 3. The existence of the support plate 106 ensures the stability of the electrode plate 3 during installation and use, and prevents it from shifting or tilting due to water flow impact or vibration. The support plate 106 can also protect the electrode plate 3, reduce the possibility of direct contact between the electrode plate 3 and the bottom of the reaction tank, and thus extend the service life of the electrode plate 3.

[0033] At the same time, a sludge chamber 104 is arranged between each reaction zone 10, and an inclined plate 103 inclined toward the sewage inlet 105 is arranged at the bottom of each reaction zone 10. The inclined plate 103 can facilitate the sludge deposited at the bottom to slide from the sewage inlet 105 to the sludge chamber 104, and a sludge discharge pipe 13 aligned with the sludge chamber 104 is arranged on one side of the box.

[0034] The inclined plate 103 provided at the bottom of the reaction zone 10 can make the sludge deposited at the bottom slide from the sewage inlet 105 to the sludge chamber 104. This design utilizes the effect of gravity, so that the sludge can slide automatically, reducing the trouble of manual cleaning. The sludge discharge pipe 13 aligned with the sludge chamber 104 provided on one side of the box body facilitates the discharge of the sludge. By regularly opening the sludge discharge pipe 13, the sludge in the sludge chamber 104 can be discharged to keep the sludge chamber 104 clean and running efficiently.

[0035] It should also be noted that a plurality of cylindrical insulating bumps 1021 (which can be set according to actual needs) are provided on both sides of the electrode plate 3. By providing a plurality of cylindrical insulating bumps 1021 on both sides of the electrode plate 3, the interval between the two electrode plates 3 can be effectively maintained. This design ensures that the electrode plates 3 will not contact each other during installation and use, thereby avoiding the risk of short circuit caused by contact. The use of insulating bumps 1021 completely isolates the electrode plates 3, effectively preventing the occurrence of short circuits and improving the safety of the entire system.

[0036] The electrode plate 3 includes a positive electrode plate 3 or a negative electrode plate 3. In this specific embodiment, the multiple electrode plates 3 in the same reaction zone 10 are actually arranged in a staggered manner of "positive electrode plate 3-negative electrode plate 3-positive electrode plate 3". At the same time, the electrode plates 3 of the same polarity are connected to the copper bracket 4 through bolts 41 and gasket assemblies, and the corresponding copper brackets 4 are connected to the corresponding positive / negative terminals. In addition, the bolts 41, the gasket assemblies and the copper brackets 4 are all coated with a layer of anti-corrosion paint.

[0037] In the same reaction zone 10, multiple electrode plates 3 are arranged in a staggered manner in the form of "positive electrode plate 3-negative electrode plate 3-positive electrode plate 3". This arrangement helps to form a uniform electric field distribution and improve electrolysis efficiency. At the same time, the alternating appearance of positive and negative electrode plates 3 avoids current short circuit or interference caused by adjacent electrode plates 3 of the same polarity. Optimize the current path: The staggered arrangement of electrode plates 3 allows the current to form an effective closed loop between the positive and negative electrodes, thereby improving the utilization rate of the current and reducing energy waste.

[0038] Furthermore, a connecting plate 32 is provided at the top of the electrode plate 3, and the connecting plate 32 is provided with a fixed connecting ear 33, and the fixed connecting ear 33 is connected to the copper bracket 4 through a bolt 41 and a gasket, and the copper bracket 4 is electrically connected to an external power supply. The corresponding copper bracket 4 is respectively connected to the positive terminal and the negative terminal to ensure that the current can be smoothly transmitted from the power supply to the electrode plate 3. The copper bracket 4 has good electrical conductivity, which can ensure the stable transmission of current and reduce energy loss caused by resistance.

[0039] The bolt 41, the gasket assembly and the copper bracket 4 are all coated with a layer of anti-corrosion paint. This measure can effectively prevent these components from being affected by chemical corrosion during the sewage treatment process, thereby extending the service life of the equipment. At the same time, the anti-corrosion paint can also improve the surface smoothness of the components, reduce the adhesion of dirt, and facilitate cleaning and maintenance.

[0040] The reaction tank housing 1 is made of insulating material. The insulating material can effectively isolate the current and prevent the current from leaking or leaking during the electrolysis process. This greatly reduces the risk of electric shock caused by current leakage and ensures the safety of the operator. In the sewage treatment process, the water may contain conductive substances. The use of an insulating material housing can prevent electric shock accidents when the operator touches it.
