The utility model discloses a metal processing additive emulsifying device which comprises a base, supports are symmetrically and fixedly connected to the upper surface of the base, round hole blocks are symmetrically and fixedly connected to the outer side wall of a servo motor, a bolt is connected to the center of each round hole block in a sleeved mode, and the bottom of each bolt is in threaded connection with the upper surface of an upper buckling cover. Lifting structures are symmetrically arranged on the two sides of the upper surface of the upper buckle cover, and the bottoms of the lifting structures are connected with the upper surface of the support. When the emulsifying device is used for emulsifying a metal processing aid, the upper buckling cover and the inner tank body can be fully buckled through the lifting structure driven by the hydraulic cylinder, the upper cover and the tank body can be tightly buckled, the tank body is made of martensitic stainless steel or austenitic stainless steel, the excellent anti-corrosion function is achieved, good performance can still be kept after long-time use, and the service life of the emulsifying device is prolonged. Therefore, corrosion and harm to equipment and the environment in the emulsifying process can be effectively reduced, and the safety and the environmental protection property of production are improved.

This application discloses a water pipe rack that is easy to disassemble, comprising: a base plate and a support. Each of the four corners of the base plate is equipped with a bolt. A slot is welded to the side wall of the base plate. An eccentric wheel is installed on the side wall of the base plate. The eccentric wheel includes an inner column and an outer column. The inner column is fixedly installed on the side wall of the base plate, and the outer column is movably sleeved outside the inner column. A plate is provided between the eccentric wheel and the slot. One end of the plate is fixed in the slot, and the other end of the plate has a semi-circular notch that engages with the eccentric wheel. The support is vertically welded to the side wall of the plate. A water pipe is hung on the support. A baffle is vertically welded to the side wall of the support. The plate welded to the water pipe support is secured by the slot and the eccentric wheel. When disassembling the support, the outer column of the eccentric wheel is rotated by the handle, and the plate is disassembled from the base plate. The operation is simple and the disassembly is convenient. No complicated tools are required, saving time and manpower. The water pipe rack uses a semi-circular arched support to facilitate the storage of water pipes, avoiding the accumulation of water pipes and occupying space. The baffle limits the water pipes and prevents them from slipping.
