Abstract

The invention provides a leakage-proof blanking device for a roller press. The leakage-proof blanking device comprises a central blanking pipe, a pneumatic rod valve, a manual rod valve, a nonmetallicexpansion joint and a connecting pipe. The manual rod valve, the nonmetallic expansion joint and the pneumatic rod valve are sequentially arranged on the central blanking pipe from top to bottom. Anupper sealing plate is arranged at the upper part of the side surface of the manual rod valve. A lower sealing plate is arranged at the lower part of the manual rod valve. A cavity between the upper sealing plate and the lower sealing plate is filled with sealing sand. An upper sealing plate is arranged on the upper part of the side surface of the pneumatic rod valve, the lower part of the side surface of the rod valve is connected with one end of the connecting pipe, and the other end of the connecting pipe is connected with a central connecting pipe. By the adoption of the leakage-proof blanking device, on the one hand, the blanking device is prevented against escape and leakage and avoids raising dust; and on the other hand, the leakage-proof blanking device meets more stringent environmental protection requirements and improves the environment.

Description

technical field [0001] The invention relates to the field of cement production machinery, in particular to a leak-proof material discharging device for a roller press. Background technique [0002] For a long time, the dry-process cement production line has used the raw material roller press feeding pipe for feeding, and the lower part of the feeding pipe of the roller press is a manual rod valve and a pneumatic rod valve to control the amount of material passing through. [0003] However, due to the inherent defects of the rod valve equipment, there is a gap of about 1mm between the rod and the rod hole, and the cement input ingredients contain a large amount of dust, which passes through the gap of the rod valve due to gravity during the feeding process. , generating dust, the situation of ash on site is very serious, polluting the environment. With the improvement of environmental protection awareness, people pay more attention to the management of equipment leakage and ...
