The stirring blades are additionally arranged in the reduction tank, so that sodium hydrosulfide raw materials in the reduction tank can be stirred, the sodium hydrosulfide raw materials can be uniformly mixed with additionally-added chemical raw materials in the reduction process, full contact and reduction reaction are ensured, the utilization rate of the internal chemical raw materials is further increased, and the production cost is reduced. Meanwhile, in order to avoid caking of the raw materials in the feeding process, the raw materials can be smashed through the smashing rod, and subsequent use is facilitated.

The invention discloses a temperature adjusting device, semiconductor process equipment and a temperature adjusting method, and belongs to the technical field of semiconductor processing. The temperature adjusting device is used for adjusting the temperature of the wafer, the temperature adjusting device comprises a shading assembly, a temperature detection assembly and a driving assembly, and the shading assembly is movably arranged between the heating source and the wafer and is used for shielding the wafer; the temperature detection element is used for detecting the temperature of the central area and the edge area of the wafer; the driving assembly is connected with the shading assembly and used for driving the shading assembly to act according to a detection signal of the temperature detection assembly so as to adjust the shading area of the shading assembly on at least one of the center area and the edge area. In the scheme, the shielding area of the shading assembly on at least one of the central area and the edge area is adjusted according to the temperature difference, detected by the temperature detection assembly, of the central area and the edge area of the wafer, it can be guaranteed that the temperatures of the central area and the edge area are the same, and therefore the wafer is prevented from deforming or jumping up from the supporting ring.

The utility model discloses a binding mouth protection device of stapler, including the hinge setting of protection baffle in the compression box of stapler, protection baffle is located the outside of the nail box of stapler, and protection baffle includes the protection board and the hinge plate of setting at the both ends of protection board, and the one end of hinge plate away from protection board is respectively hinged and set in the both sides of compression box. The hinge end of protection board and hinge plate will naturally hang down and lean on the base of stapler under the action of gravity, and the binding mouth of stapler is shielded and protected, can effectively avoid the user or other people mistake and stretch the hand into the binding mouth of stapler when binding, and because setting protection baffle, the user can also feel the existence of protection baffle when binding, and more attention is paid on the binding mouth, effectively avoid the user in the distraction of binding, cause the consequence of being stapled and being hurt by stapler slightly careless.

The utility model provides a bus station display board, which relates to the technical field of display boards and comprises a mounting frame mounted on the ground, a display board fixedly connected with the mounting frame and a shielding component fixed at the top of the mounting frame. The shielding assembly comprises a storage frame fixed to the top of the mounting frame, a shielding telescopic plate which is arranged in the storage frame and stretches out and draws back in the storage frame, and two telescopic assemblies which are arranged in the storage frame in a left-right spaced mode, so that the shielding telescopic plate stretches out of the storage frame or is contained in the storage frame under the action of the telescopic assemblies. A display component is arranged on the display board so as to display contents; when the passenger flow volume is large or in rainy days, the shielding telescopic plate can extend out of the storage frame. Therefore, the shielding area can be enlarged, so that the shielding in a larger range can be realized. In this way, passengers can watch the display board more conveniently and can have a rest in the area.

This utility model relates to a roller shutter device, belonging to the field of agricultural facility technology, specifically a roller shutter device for agricultural greenhouses. It includes multiple sets of columns, with a truss fixedly installed at the ends of every two adjacent columns, and a glass outer wall fixedly installed between every two adjacent columns and trusses. It also includes a winding assembly. This utility model achieves the desired high-strength roller shutter performance, such as the rolling effect of heavy-duty insulation curtains, while simultaneously solving problems such as motor blocking light, large space occupation, and end-interference. It addresses the shortcomings of existing greenhouse curtain rolling devices, which use built-in tubular motors, resulting in low power and poor durability, making them unsuitable for high-strength roller shutters. Furthermore, external fixed motors, connected to the roller shutter tube via swing arms, occupy a large space, block light, and are unsuitable for confined spaces.
