The invention relates to the technical field of wastewater treatment, in particular to an electroplating nickel-chromium wastewater treatment device which comprises a sewage tank, a water suction pump is fixedly connected to the upper surface of the inner wall of the bottom of the sewage tank, one end of the water suction pump is fixedly connected with a door-shaped pipeline, and the other end of the door-shaped pipeline extends into a flocculation tank. Four square columns are fixedly connected to the four corners of the lower surface of the flocculation tank, stirring assemblies are fixedly connected to the upper surfaces of the tank walls of the two sides of the flocculation tank, and one end of the bottom of each stirring assembly is connected with an anti-condensation assembly in a meshed mode. According to the nickel-chromium electroplating wastewater treatment device, the water pump is matched with the flocculation basin, the sedimentation basin and the filter press, metal impurities such as nickel and chromium contained in wastewater are sequentially neutralized, stripped and filtered, the site requirement of the wastewater treatment device can be reduced through flow matching, and the production requirements of many related industries such as chemical engineering, metal or sewage processing plants are met; operation is convenient, and efficiency is high.

This invention discloses a pipe expansion joint reinforcement device and its construction method, comprising: two auxiliary pipe fitting assemblies, detachably fitted onto opposite ends of a pipe expansion joint; a support beam assembly, disposed on one side of the pipe expansion joint, the support beam assembly being arranged along the length direction of the pipe expansion joint, the support beam assembly including a first beam segment, a second beam segment, and an elastic element, the first beam segment forming an axially arranged socket channel, one end of the second beam segment slidingly disposed in the socket channel, and the elastic element connecting the first beam segment and the second beam segment; and a quick-connect assembly, the other ends of the first beam segment and the second beam segment respectively connected to the two auxiliary pipe fitting assemblies. This invention solves the problem that the pressure-bearing capacity of existing HDPE pipe expansion joints is relatively weak and prone to disengagement.

This invention relates to the field of desulfurization technology for reclaimed rubber, specifically a desulfurization treatment device and method for waste tire reclaimed rubber, comprising: a treatment tank, on which a gas guide pipe is installed, the gas guide pipe having an "L"-shaped structure; a support arm, connected to the gas guide pipe, the support arm having multiple pressure relief ports equidistantly arranged on one side facing the bottom of the treatment tank; a pressure sensing component, connected to the gas guide pipe, the pressure sensing component being able to drive the support arm toward or away from the bottom of the treatment tank according to the pressure in the gas guide pipe; a guide plate, disposed in the treatment tank and cooperating with the pressure relief ports, enabling the gas and liquid in the treatment tank to rotate; and a linkage component, connecting the pressure sensing component and the guide plate, the linkage component being able to drive the guide plate to rotate to change its deflection angle when the pressure in the gas guide pipe changes, thereby increasing the retention time of the waste gas in the purification liquid and improving the treatment effect.

The invention discloses mine stone screening equipment which comprises a fixing structure, a screening structure and a dust removal structure, the screening structure is fixedly connected to the inner side surface of the fixing structure, the dust removal structure is fixedly connected to the outer side surface of the fixing structure, and the fixing structure comprises a feeding unit, a door closing unit and a door opening and closing unit. The closing door unit is inserted into the top surface of the feeding unit, the opening and closing door unit is fixedly connected to the outer side surface of the feeding unit, and the screening structure comprises a screening unit, a supporting unit and a motor unit. According to the mine stone screening equipment, the funnel is arranged, clear water can be poured into the water tank through the water inlet pipe, the exhaust fan is arranged on the inner side of the dust suction pipe, dust generated in the device shell is pumped out through the dust suction pipe, the water tank is used for bearing the clear water and can filter the dust, and sewage generated after the clear water is filtered can be discharged through the blow-off pipe; the dust filter can effectively filter dust, and has the advantages of being high in practicability and capable of preventing dust leakage.

This utility model provides a sorting device for water chestnut processing, belonging to the field of agricultural crop processing technology. The device has a simple and ingenious structure, is easy to install, and achieves good sorting results. The filling hopper is fixed on a support frame, and a uniform material plate is slidably installed below the outlet of the filling hopper. The uniform material plate is inclined. Both the conveying component and the sorting component are fixedly installed. The feeding end of the conveying component is connected below the discharging end of the uniform material plate, and the feeding end of the sorting component is connected below the discharging end of the conveying component. Sorting holes are opened on the feeding belt of the sorting component. Multiple sorting components are arranged sequentially along the feeding direction, with the hole diameter of each component increasing progressively. The feeding end receives the previous discharging end. This device has a simple structure, is easy to install, has a large sorting capacity, and can quickly sort water chestnuts. The progressively larger sorting holes allow for precise, step-by-step sorting of water chestnuts, resulting in excellent sorting performance.
