The utility model discloses a wiredrawing heat preservation device for chemical fiber rope net production, which comprises a water tank and inlet and outlet notches, the inlet and outlet notches are respectively arranged above the left side and the right side of the water tank, three groups of upper gears are movably connected above the front end of the inner side of the water tank, and three groups of lower gears are movably connected below the front end of the inner side of the water tank. Guide rollers are transversely welded to the rear portions of the upper gear and the lower gear respectively. According to the wiredrawing heat preservation device for chemical fiber rope net production, guide rollers are transversely welded to the rear portions of an upper gear and a lower gear correspondingly, silk threads can be pressed by a positioning plate controlled by an air cylinder, movement of the silk threads can be stopped, every two vertically-adjacent guide rollers in a water tank form a group, and a main guide gear is rotated after a motor is started; the upper gear opposite to the main guide gear is directly pushed to operate, the lower gear opposite to the main guide gear is pushed to rotate reversely under the limitation of the transmission gear, then the silk threads are transmitted, and the problem that the heat preservation path is short is solved.

The application discloses a liquor tailing acid substance extraction method in liquor brewing and liquor, and comprises the following steps of pretreatment, selective adsorption, gradient desorption, membrane separation and purification and liquor body blending. The chelation precipitation-microfiltration coupling process is adopted in the pretreatment to remove metal ions and colloidal impurities; the acid substances are specifically adsorbed through a hexanoic acid molecular imprinting polymer adsorbent, and step-by-step elution is realized by combining with gradient pH desorption; high-purity acid concentrated solution is obtained through nanofiltration membrane separation and activated carbon adsorption, and after screening, the high-purity acid concentrated solution is blended with a base liquor body to improve the quality of the liquor.

The multifunctional brush comprises a handheld rod, an adjusting cavity is formed in the handheld rod, an electric push rod is installed at one end in the adjusting cavity, a transmission rod is fixed to the output end of the electric push rod, a shaft sleeve is arranged at one end of the transmission rod, a connecting rod is installed at one end of the shaft sleeve, and the connecting rod is connected with the adjusting cavity. A bearing shell is fixed to one end of the connecting rod, a motor is installed in the bearing shell, a rotating disc is fixed to an output shaft of the motor, and a brush head is installed on the rotating disc. The cleaning device has the beneficial effects that by arranging the electric push rod, the motor, the rotating disc and the brush head, in the cleaning process, the motor drives the connecting rod to rotate through the rotating disc, meanwhile, the brush head can automatically clean the sea knife in cooperation with stretching and retracting of the electric push rod, the cleaning efficiency is high, and workers are prevented from bearing unpleasant smells volatilized by cleaning agents for a long time; and the cleaning effect is good.
