This utility model discloses a cleaning device for metal product processing, including a cleaning table. A placement ring is rotatably mounted on the cleaning table via a bearing. A box is fixedly mounted on the cleaning table, and a door is hinged to one side of the box. A protective shell is fixedly mounted at the lower end of the cleaning table. A first motor is fixedly mounted inside the protective shell. A limiting shell is fixedly mounted on the cleaning table, and a bidirectional lead screw is rotatably mounted inside the limiting shell. The drive end of the first motor extends into the limiting shell and is fixedly connected to the bidirectional lead screw. Two drive seats are threaded onto the bidirectional lead screw. Two first cleaning brushes are movably mounted on both sides of the limiting shell. Support rods are hinged between the two drive seats and the two first cleaning brushes. This device can spray water and brush the interior of metal products used as containers during cleaning, thereby ensuring the cleaning effect and preventing impurities from remaining inside the metal products.

This utility model discloses a temperature control device suitable for semiconductor equipment, including a temperature-controlled mixing mechanism and a heating device installed at the bottom of the temperature-controlled mixing mechanism. A circulating mixing mechanism is provided on the outside of the temperature-controlled mixing mechanism, and a circulating pump is located on the outside of the circulating mixing mechanism. The temperature-controlled mixing mechanism includes a meshing gear ring, and a mixing rotating disk is rotatably connected to the bottom of the meshing gear ring. Several meshing gears are meshed on the inner side of the meshing gear ring, wherein the number of meshing gears is three. A rotating motor is provided on the top of the meshing gear ring, wherein a drive gear is fixedly connected to the output end of the rotating motor. The drive gear meshes with the meshing gears, so that the meshing gears drive the mixing rotating disk and three vertical stirring rods to revolve, and at the same time, the vertical stirring rods drive the vertical auger to rotate, thereby realizing the up-and-down stirring of the cleaning liquid, which can not only improve the mixing efficiency of the cleaning liquid, but also achieve uniform heating of the cleaning liquid.
