Embodiment 1

[0021] Please refer to figure 1 , 2 , 3, 4, the automatic control system of calcium carbide preparation and feeding of acetylene generator is carried out according to the following process:

[0022] 1. Generator small storage hopper for material preparation

[0023] When selecting the generator and metering hopper that need to prepare materials, the program will start the reversible belt (A81009A / B), 2# belt conveyor A81008A / B, vibrating feeder A81007A / B / C / D in sequence according to the set program, The opening of the vibrating feeder changes from 0 to 8% after a delay of 1s, then to 15% after a delay of 1s, and then to 15% after a delay of 2s. At the same time, "A / B line interlock" is automatically put into use. When the weight of the weighing hopper W81001A / B / C / D is low, the vibrating feeder A81007A / B / C / D will stop and delay Finally, the reversible belt (A81009A / B) stops, the "interlock of A / B line" is automatically released, and it prompts "the preparation of the small...

Abstract

The invention discloses a calcium carbide preparing and feeding automatic control system of an acetylene generator. The automatic control system comprises a generator material preparation control module, a generator feeding control module, a first vibrating feeding machine (1), a metering hopper (2), a second vibrating feeding machine (3), a belt conveyer (4), a reversible belt conveyer (5), a generator small feeding storage hopper (6), a generator upper feeding storage hopper (7), a generator lower feeding storage hopper (8), a vibrating feeder (9) and a generator (10). Various interlocks are set during automatic operation, so that heavy material preparation, heavy material adding, replacement overpressure and overtime are avoided, all devices are interlocked when one device goes wrong, the automation level of an acetylene workshop is greatly improved, and the fault rate of a feeding device and the labor intensity of staff in operation are reduced.

Description

technical field [0001] The invention relates to the technical field of chemical equipment and instrument automation, in particular to the technical field of equipment for producing polyvinyl chloride raw material gas acetylene gas by the calcium carbide method and the technical field of chemical instrument automation. Background technique [0002] In recent years, with the rapid development of the national economy, the hard PVC processing market has increased sharply, and the cost of the petroleum ethylene method has risen, which has greatly promoted the unconventional development of the calcium carbide method PVC production device. The total production capacity of domestic PVC devices has reached more than 20 million tons. More than 70% of raw materials for the production of polyvinyl chloride resin come from calcium carbide. The process of producing polyvinyl chloride raw material gas acetylene gas by calcium carbide method has the characteristics of large dust, flammable ...
