The invention belongs to the technical field of plastic granulation and relates to an extrusion filter. The extrusion filter comprises a casing, a feeding connector arranged on the casing, a heating temperature control device and a material extrusion device; a discharging port of the material extrusion device is connected with an impurity filter with a filter screen; an impurity scraping and discharging device for scraping impurities on the filter screen into an impurity storage cavity and discharging the impurities to the outside of the impurity filter is arranged in an inner cavity of the impurity filter; the filter screen formed by a plurality of radially-arranged filtering holes is arranged on the side wall of the inner cavity of the impurity filter; and a discharging connector communicated with a discharging cavity at the outer side of the filter screen is arranged on the outer wall of the impurity filter. The extrusion filter has the benefits that the impurities generated in the granulation and the production of the extrusion filter can be cleared without machine halt; and the extrusion filter has the advantages of easiness in structure manufacture, high strength, uneasiness in blockage, long service life, high production efficiency and low production cost and is suitable for the granulation of waste plastics.

The invention discloses an automatic duck gizzard and duck glandular gastro-esophagus separation device. The automatic duck gizzard and duck glandular gastro-esophagus separation device comprises a duck gizzard bag driven by a chain, and a duck glandular gastro-esophagus and content separation mechanism and a duck gizzard and duck glandular gastro-esophagus separation mechanism, which are arranged on a working table and are connected end to end, wherein the duck glandular gastro-esophagus and content separation mechanism is provided with a blade I with a sharp end part and a food removing pulling sheet with the diameter more than a duck glandular gastro-esophagus, and the blade I is close to the food removing pulling sheet; the duck glandular gastro-esophagus can be cut apart very well, and contents in the duck glandular gastro-esophagus are scraped very well; the duck gizzard and duck glandular gastro-esophagus separation mechanism is provided with a guide platform for forming a gap and the gap is provided with a blade II; after the contents is separated from the duck glandular gastro-esophagus, the a duck gizzard can be separated from the duck glandular gastro-esophagus, without changing a container. The automatic duck gizzard and duck glandular gastro-esophagus separation device has the beneficial effects that according to the description, the automatic duck gizzard and duck glandular gastro-esophagus separation device is simple in structure and reasonable in design; the labor is released, the working efficiency is improved and the production quality is also improved.

The invention relates to treatment equipment for a nonmetal liquid, in particular to a magnetic roller type filter for removing ferreous substances, surface oil dirt and the like of a nonmetal mixed liquid. The magnetic roller type filter comprises an accommodating cavity with a liquid inlet and a liquid outlet; a dustproof cover is arranged on the accommodating cavity; a magnetic roller and an oil removal roller are arranged in the accommodating cavity and both driven by a speed reducer motor to rotate; a slag scrapping device basically clung to the surface of the magnetic roller is arranged at the part, above a liquid level, of the magnetic roller; an oil scrapping device closely lung to the surface of the oil removal roller is arranged at the part, above the liquid level, of the oil removal roller; a flow guide plate for dividing the accommodating cavity into a slag removing cavity and a purification cavity is arranged below the magnetic roller and the oil removal roller. The magnetic roller type filter not only can remove the ferrous substances and the oil dirt, but also has a high filtration effect and a stable structure.

The invention discloses an oil sludge demulsifier and an oil sludge treatment process. The oil sludge demulsifier comprises the following components in parts by weight: 6-30 parts of fatty acid methyl ester ethoxylate, 2-13 parts of lauramidopropyl hydroxy sulfoBetaine, 0.5-1 part of a green accessory ingredient and 56-91 parts of water. The oil sludge treatment process comprises the following steps: enabling oil sludge in a raw material storage sludge tank to enter a sludge mixing tank; adding the oil sludge demulsifier for demulsification treatment; enabling demulsified oil sludge to enter a stacked spiral type sludge dewatering machine for solid-liquid separation to obtain a filter liquor and a sludge cake; enabling the filter liquor to enter a gas-liquid mixing tank to be mixed with air; enabling the mixture to enter a separation tank for three-phase separation of oil, water and sludge. The oil sludge treatment process can reduce the moisture content of oily sludge from 80-98% to about 50%, can further recycle most crude oil in the oily sludge, and greatly reduces the difficulty of sludge follow-up treatment.
