The utility model discloses solid-liquid separation industrial wastewater auxiliary treatment equipment convenient for replacing a filter plate. The solid-liquid separation industrial wastewater auxiliary treatment equipment comprises a box body, the filter plate and a replacement mechanism, the filter plate is arranged in the box body, and the replacement mechanism is arranged on the outer wall of the box body and assists in replacing the filter plate; the filter plate comprises a mounting frame and a filter screen mounted on the mounting frame, and grooves are formed in the two sides of the mounting frame; an inlet and an outlet are formed in two sides of the box body; the outlet and the inlet are each provided with a blocking mechanism used for blocking the inlet and the outlet. A water outlet pipe and supporting legs are arranged at the bottom of the box body; a supporting groove is formed in the inner wall of the box body and used for inserting the filter plate; a supporting plate is arranged on the side wall of one side of the outlet of the box body and is used for supporting the withdrawn filter plate. The filter plate can be stably, orderly and independently replaced without interfering with normal operation of other mechanisms under the assistance of the replacement mechanism, and the replacement process is efficient and rapid.

The utility model relates to material conveying equipment technical field discloses a double curve shrimp type coal hopper, including the funnel shell, the outer wall fixedly connected with the clamping mechanism of funnel shell, the bottom fixedly connected with the discharging mechanism of funnel shell, the clamping mechanism includes a plurality of clamping bottom plate, a plurality of clamping bottom plate one side fixedly connected in the outer wall of funnel shell, a plurality of clamping bottom plate another side all fixedly connected with right angle support frame, the one side mounting of right angle support frame has hydraulic cylinder no.

This utility model relates to the field of display panel technology, specifically an adjustable-height display panel, including a display frame. An electric telescopic rod is fixedly connected to the bottom of the display frame, and a solar panel is installed on the top of the display frame. A poster mounting mechanism is installed inside the display frame. The advantages are as follows: by cooperating with the display frame and the poster mounting mechanism, the top of the poster is clamped and fixed by several fixing clips. Rotating the handle drives the threaded rod to rotate, causing the threaded rod and the movable block to perform threaded movement, which in turn drives rotating rod one and rotating rod two to rotate. This changes the height of the scissor-type adjusting component one and the connecting component, allowing the movable rod to slide along the inner wall of the display frame to the top, thus unfolding and fixing the poster inside the display frame. This makes poster replacement smoother, reduces installation time and labor costs, and effectively increases safety during the replacement process.
