Description

Technical Field

[0001] The utility model relates to the field of wastewater separation and treatment used in chemical processes, and more specifically, to a wastewater separation and treatment device used in chemical processes. Background Art

[0002] Chemical process, also known as chemical technology or chemical production technology, refers to the method and process of converting raw materials into products mainly through chemical reactions, including all measures to achieve this series of transformations. In order to make the raw materials meet the state and specifications required for chemical reactions, according to specific circumstances, most of the different raw materials in the chemical process need to undergo a variety of different processing treatments such as mixing, concentration, mixing, emulsification or crushing (for solid raw materials). In the treatment of various chemical raw materials, a large amount of wastewater is inevitably generated. If this type of wastewater cannot be treated in a timely and efficient manner, it will easily cause pollution to the surrounding environment and seriously affect people's health;

[0003] However, most of the existing chemical process wastewater separation devices use direct centrifugation to perform simple solid-liquid separation to achieve the purpose of separating solid impurities in the wastewater. This method can only perform primary physical cleaning treatment on the wastewater, and there is no auxiliary component specifically used to evenly mix additives, resulting in a low purification rate of the wastewater and a single overall function. Therefore, it is necessary to improve the above structure to improve the performance of the wastewater separation treatment device;

[0004] Among its prior art patents, such as the authorization announcement number CN219009985U, a wastewater separation and treatment device for chemical processes is disclosed, which is characterized in that: the cyclone main pipe is rotatably installed on the support frame through a rotary seat, and the cyclone main pipe is driven to rotate by a motor installed on the rotary seat, and the reagent mixing mechanism is movably inserted from below inside the overflow pipe and the cyclone main pipe, and the position of the reagent mixing mechanism corresponds to the position of the cyclone main pipe, and additives are added to the wastewater through a mixing pipe installed by the reagent mixing mechanism. In this case, a cyclone main pipe is used to separate the solid and liquid from the wastewater, and the centrifugal stratification of the solid and liquid is achieved, which effectively reduces the convection area between the solid and the liquid, and improves the solid-liquid separation effect and separation efficiency. At the same time, the additives are fully mixed into the wastewater through the mixing pipe of the reagent mixing mechanism, which can increase the contact area between the additives and the wastewater, thereby improving the mixing uniformity of the additives and the wastewater;

[0005] In the above-mentioned patent, a mixing tube is used to introduce additives into the barrel for mixing, but there is no stirring mechanism. The additives and the mixing tube are self-fused, and the mixing efficiency is low. In addition, during the separation cyclone sedimentation, slag may still float to the water surface and be taken out together during the output, resulting in incomplete wastewater separation. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a wastewater separation and treatment device for chemical processes, which feeds water on one side and additives on the other side, adopts an active rotary stirring mechanism to stir the wastewater and additives, which can fully blend and improve efficiency, and is provided with a filter press structure to further filter the wastewater and improve the separation completeness performance.

[0008] A wastewater separation and treatment device for chemical process, comprising a separation cylinder, the separation cylinder adopts a conical cylinder structure and a bottom variable diameter contraction structure, a cover plate is fixed on the upper surface of the separation cylinder, a motor is fixed on the surface of the cover plate, a rotating rod is fixedly connected to the lower surface of the driving shaft of the motor, a curved stirring section is arranged at the lower end of the rotating rod, a stirring blade is fixed on the outer surface of the curved stirring section of the rotating rod, a cylinder is fixed on the upper surface of the cover plate, the end face of the propulsion rod of the cylinder is fixedly connected to the upper surface of the ring frame, a supporting rib is arranged on the inner side of the ring frame, the end face of the propulsion rod of the cylinder is fixed to the upper surface of the supporting rib in the ring frame, a filter screen is fixed in the cavities on both sides of the ring frame, a liquid inlet pipe is arranged on one side of the upper end of the separation cylinder, an additive conduit is arranged on the other side of the upper end of the separation cylinder, a derivation pipe is arranged on the inner surface of the lower end of the separation cylinder, water is introduced on one side and additives are introduced on the other side, an active rotary stirring mechanism is adopted to stir the wastewater and the additives, which can be fully integrated to improve the efficiency, and a filter press structure is arranged to further filter the wastewater to improve the separation completeness performance;

[0009] Furthermore, the separation cylinder is a conical cylinder structure, and a reducing mouth structure is arranged at the bottom.

[0012] Furthermore, the stirring blades are arranged on the left and right outer surfaces of the curved stirring section of the rotating rod to facilitate stirring. During rotation, the curved stirring section rotates, which can drive the stirring blades on both sides to rotate, thereby rotating and stirring the treated liquid, accelerating the integration with additives, and starting solid-liquid separation.
