The utility model relates to fender mold technical field, concretely is a fender mold, including bottom plate, bottom plate top setting lower mould, upper mould, mounting bracket, hydraulic pressure rod and lift plate, lift plate bottom even fixed mounting has a plurality of fixed links, and fixed link bottom terminal is fixedly connected with upper mould top, still fixed mounting has material box on the lift plate, and material box bottom fixed mounting has the discharge pipe, still fixed mounting has the discharge gate on the discharge pipe, and the discharge gate is fixedly connected with the injection port on the upper mould. The device can stably and evenly convey the raw materials in the material box to the injection port of the upper mould through the auger conveying disc arranged in the discharge pipe, ensures the efficiency of feeding, improves the forming quality of the fender, at the same time, the stirring shaft, stirring rod and stirring blade arranged on the cover plate can fully stir the raw materials in the material box, reduces the occurrence of raw material solidification phenomenon, reduces the raw material waste.

This invention discloses a low-temperature dry dust removal device for phosphorus furnace gas, comprising: two sets of series-connected metal felt filter screens, filter screen electric heaters, a backflushing system, a dust collection funnel, a spiral dust collector, and a fan. The outlet pipe of the yellow phosphorus furnace gas is connected to the inlet of the series-connected metal felt filter screens. Each metal felt filter screen is equipped with an electric heater. The backflushing system achieves dust removal by adjusting the valve switch to reverse the gas flow. The filter cake outlet of the metal felt filter screen is connected to the inlet of the dust collection funnel. The outlet of the metal felt filter screen is connected to the inlet of the fan. The dust outlet at the bottom front side of the metal felt filter screen and the dust collection funnel are sealed and connected to the dust inlet of the closed spiral dust collector. The outlet of the fan is the exhaust port of the device. This device can solve the problem of yellow phosphorus furnace gas condensation clogging and corrosion of equipment, achieve low-temperature and high-efficiency dust removal of yellow phosphorus furnace gas, and improve filtration efficiency and phosphorus yield.
