A filter device for aviation fuel oil production. The invention belongs to the field of fuel oil filter devices. Connected through the inner holes of the annular partition, several series of filter holes are evenly opened on the outer periphery of the filter cartridge, and the scraper is installed movable in the filter cartridge, and several through-holes of the sinker are evenly opened on the scraper, and the through-holes of the sinker are hinged and installed by torsion springs The filter screen plate and the tank body are provided with an oil inlet and an oil outlet, and the corresponding rolling gears on the periphery of the filter cartridge are respectively fixedly installed with bar-shaped racks, and the rolling gears mesh with the corresponding bar-shaped racks respectively. The invention can use the ejector rod to block the filter hole when scraping the filter cartridge, so that the inner wall of the filter cartridge can be scraped and cleaned during the filtering process, and at the same time, the scraped filtrate can be gathered in the filter cartridge Top, reduce secondary pollution of unfiltered fuel oil by filtrate.

The invention relates to the technical field of dust removal for cement clinker, in particular to a dust removal device for an automated cement clinker production line, which includes a support seat, a conveying mechanism, a dust cover, a side wall dust removal mechanism and a top dust suction mechanism. The side wall dust removal mechanism and the top dust suction mechanism designed by the present invention can absorb the dust in the dust cover in all directions, and the U-shaped seat in the side wall dust removal mechanism is provided with dust suction holes in multiple directions, so that the side wall dust removal The mechanism can absorb the dust in an all-round way, avoiding the problem of dirty working environment caused by the dust flowing out from the gap. The anti-adhesion dust scraping mechanism and the dust scraping group are respectively set in the side wall dust removal mechanism and the top dust suction mechanism. In order to scrape and clean the adhered dust, prevent the dust from blocking some suction holes and suction holes, resulting in poor dust suction effect.

The invention discloses an injection mold with a water blowing device, which comprises a base. The mold base, the base is provided with a water tank, the water tank is connected with the cooling chamber, the side wall of the cooling chamber is provided with a water blowing chamber, the side wall of the water blowing chamber is provided with a water blowing port connected with the cooling chamber, and the cooling chamber is far away from the water blowing port The side wall of one end of the cooling chamber is communicated with a collection tank, and the end of the collection tank far away from the lower die base is communicated with a first conduit, the first conduit is installed with a first control valve, and the side wall of the cooling chamber is connected with a second conduit , the second control valve is installed on the second conduit, the end of the second conduit away from the lower mold seat is communicated with a third conduit, and the first conduit is communicated with the third conduit. The invention can effectively clean the water remaining in the cooling cavity to prevent the mold from rusting, and in addition, can effectively improve the cooling efficiency of the mold during injection molding.

The invention discloses an anti-clogging valve for petroleum equipment, which relates to the technical field of petroleum. The anti-clogging valve for petroleum equipment includes a valve body. The valve core is connected with a valve core in rotation. The valve core is in the shape of a plunger. A regulating box is provided, the valve stem is fixedly connected to the center of the top of the valve core, and the valve stem rotates through the valve body and extends to the interior of the regulating box, and the valve stem is fixedly sleeved with a first worm gear, and the first worm gear is meshed with a second a worm. In the present invention, by setting the oil cleaning device, after the use of the valve core, the clean water heated and dosed inside the cleaning water tank is flushed from the flow hole of the valve core, and the oil left on the inner wall of the flow hole is scraped off through the oil cleaning device, thereby preventing The oil left inside the flow hole leads to the blockage of the flow hole, so that the valve does not need to be removed and cleaned separately, thereby improving the cleaning efficiency and reducing the loss of manpower and material resources.

The invention discloses an anti-clogging filter press for grease processing which is convenient for scraping inner wall materials. Both are equipped with electric slide rails, and the upper end of the electric slide rails is equipped with a mounting seat. The upper surface of the mounting seat is welded and fixed with a mounting frame. Both ends of the plate are fixedly connected to the base, the front and rear side walls of the filter press plate are integrally provided with support blocks, and the crushing chamber is located at the lower end of the base. The anti-clogging filter press for grease processing, which is convenient for scraping the material on the inner wall, facilitates the scraping and cleaning of the material on the side wall of the isolation membrane, effectively avoids the phenomenon of clogging, and facilitates the next operation. The material can be collected in a centralized manner, which greatly reduces the workload of the staff, improves the practicability of the device, and is easy to use.
