The invention belongs to the technical field of manufacturing high-voltage electric porcelain insulators, in particular to a device and method for manufacturing high-voltage electric porcelain insulators. The following solutions are now proposed, including a fixing seat. Both ends of the top outer wall of the fixing seat are fixedly connected with a fixing plate, and two The outer walls on the opposite side of the fixing plate are fixedly connected with abutting brackets, and the top outer walls of the two abutting brackets are fixedly connected with connecting springs at an equal distance. In the present invention, a blower blanking component is provided, and during the iron removal operation of the raw materials after ball milling, the blower is started, and the blower blows a large amount of gas into the hollow ring frame, and this part of the gas passes through the spiral air supply blades on the air guide tube. The helical gas accelerates the sliding of the raw material from the conical adsorption cover. The helical gas can realize all-round blowing on the outside of the magnet bar, improve the blowing effect, and ensure that the raw material will not be long-term. It is adsorbed on the outer wall of the conical adsorption cover to improve the recovery efficiency of raw materials.

An easily removed surficial coated layer of the metallic product to be cold-extruded is prepared from gypsum, machine oil and lubricating grease in weight ratio of 1:(3-10): (0.1-0.8) through mixing. The thickness of coated layer is 100-250 microns.

The invention relates to a technology for high-efficiently recycling soldering tin of discarded printed circuit boards, and a device. In a sealed system, in which liquid heat conducting medium exists, discarded printed circuit boards to be processed and welded with electronic parts are put in a swivel which is provided with a plurality of filtering holes and immersed in the heat conducting medium, the temperature is risen until the soldering tin is melted, after the temperature is constant, the swivel is rotated to centrifugally separate solid and liquid, the soldering tin leaks from the filtering holes, deposits at the bottom and is cooled into ingot, and the electronic parts are separated from the discarded printed circuit boards correspondingly. The method for recycling the soldering tin of discarded printed circuit boards has no environmental pollution, low energy consumption and high efficiency, and can create good condition for high-efficiently recycling other metals.

The invention discloses a thread scrape filter cleaning method which is designed to solve the problems of incomplete cleaning and easy blocking and the like in the present thread scrape filter. The thread scrape filter cleaning method is as follows: air is blown to a filter shell, so that disturbance is formed to the fluid at a zone, where a filter gauze in a filter is arranged, further, impurities on the filter gauze separate from the filter gauze. According to the thread scrape filter cleaning method, the impurities on the filter gauge of the filter can be removed more completely and the cleanness of the filter is improved; and the method is applicable to various filters for filtering fluid.
