This utility model belongs to the field of sludge filtration technology and discloses a dynamic sludge filtration device, including a housing. A filtration unit and a discharge unit are connected to the outside of the housing via a rotating motor and a discharge motor, respectively. The filtration unit and discharge unit are located inside the housing. A water pumping unit is located at the top of the housing and connected to the water pumping unit via a filtration water pumping pipe. The discharge unit is located at the bottom of the filtration unit and the water pumping unit. This utility model can increase the sludge contact area and filtration area, allowing liquid to penetrate into the filter housing more quickly. Combined with the rotating water pumping component, the liquid is promptly extracted, improving the speed and efficiency of sludge dewatering and shortening the processing cycle. The rotating motor drives a rotating rod, which in turn causes the filter housing to rotate within the sludge. Dewatering is achieved using the principle of free liquid permeation. Compared to traditional methods that rely on strong external force for dewatering, this effectively reduces the moisture content of the filter cake and significantly reduces energy consumption.

This utility model provides a film-pulling assembly for a sealing machine, belonging to the technical field of sealing machine technology. It includes a support frame that can slide linearly on the sealing machine; a clamping structure fixed to the support frame, comprising a hinged movable clamping plate, the rotation of which clamps or releases the material; a reset component connected to the movable clamping plate, used to drive the movable clamping plate to rotate and then push it back to its original position; and an electromagnetic component that indirectly drives the movable clamping plate to rotate via electromagnetic force. This utility model allows the reset component to reset the moment the electromagnetic component stops working, thus enabling the reset component to drive the clamping mechanism to clamp and fix the material. This allows the material end to be pulled during the movement of the film-pulling assembly, thereby indirectly improving material processing efficiency.

This invention discloses a transformer lead fixing device with deformation self-compensation function, relating to the field of transformer technology. The invention includes a fixing plate fixed to the transformer housing, a lead fixing component, a deformation self-compensation mechanism, and a pin mechanism. The deformation self-compensation mechanism includes a clamping component fixed to the end of the lead and multiple stops disposed on the fixing plate. The clamping component has a multi-segmented bent elastic structure, and the stops have inclined abutment surfaces. The pin mechanism adjustably mounts the lead fixing component to the fixing plate. When the lead fixing component is driven to move closer to the transformer housing, the clamping component and the inclined abutment surfaces of the stops abut against each other, generating elastic deformation and achieving electrical contact between the clamping component and the terminal block. This invention, through the multi-segmented bent elastic structure of the clamping component and the unidirectional displacement adjustment of the pin mechanism, achieves adaptive compensation for deformation caused by thermal expansion and contraction and vibration, ensuring long-term stable electrical contact between the terminal block and the lead, and facilitating subsequent maintenance and adjustment.
