Description
Technical Field
The invention relates to the technical field of anode rapping used on electric dust collectors for cement, power plants and coal mines,
in particular to a pneumatic hammer type anode rapping device.
Background
In order to guarantee the dust removal effect, a plurality of anode plates are used for removing dust in the design of the electric dust remover, the anode plates close to the inlet are attached with more dust, the anode plates far away from the inlet are attached with less dust, the rapping period of the anode plates is different, the rapping period of the anode plates close to the inlet is short, and the rapping period of the anode plates far away from the inlet is long. In the traditional anode rapping device, a plurality of rapping hammers are arranged on a transmission shaft, the transmission shaft is rotated to drive the rapping hammers to rotate, the rapping hammers on an anode plate are knocked by the rapping hammers, and rapping periods are consistent. The invention solves the problem of consistent rapping period and reduces secondary dust.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects of the background technology, and provide a vibrating device which has simple and reasonable structure, changes the traditional thought, solves the problem of consistent vibrating period and reduces secondary dust.
The technical scheme adopted is as follows:
a pneumatic hammer type anode rapping device comprises an anode rapping device consisting of a pneumatic rapping hammer (1) and a rapping anvil (2). The method is characterized in that: the pneumatic knocking hammer (1): is an integral part. The rapping anvil (2): the parts are welded by flanges and round steel and then are subjected to heat treatment.
The pneumatic knocking hammer (1): the working principle is as follows: under the condition that compressed air (more than 3 kg/cm) is not introduced into the pneumatic knocking hammer, the magnetic piston I is tightly attached and fixed on the base plate II by virtue of strong magnetic force. When the three-way electromagnetic valve is electrified, compressed air flows into the pneumatic knocking hammer body, the pressure in the pneumatic knocking hammer body is increased, when the pressure is larger than the magnetic force, the magnetic piston is separated from the substrate at a high speed, and strong counterattack force is generated due to the reaction force of strong magnetic force. The magnetic piston falling at high speed impacts the base plate, the impact force is transmitted to the rapping anvil and the anode plate, the attached dust is knocked down by the strong impact force, compressed air in the pneumatic rapping hammer body is exhausted through the three-way electromagnetic valve when the three-way electromagnetic valve is stopped to be electrified, then the magnetic piston is slowly lifted up and then approaches the base plate by virtue of the return spring, and the magnetic piston is tightly connected to the base plate by magnetic force to return to the initial state.
One end of the rapping anvil (2) is fixed at the rapping part of the anode plate, and the other end is connected with the pneumatic rapping hammer, so that the impact force generated by the pneumatic rapping hammer is transmitted to the anode plate to knock off the attached dust.
1. The installation sequence of the pneumatic hammer type anode rapping device is as follows: the rapping anvil (2) is fixed on the anode plate and then connected with the pneumatic rapping hammer (1) through a bolt.
2. The specific technical scheme of the pneumatic hammer type anode rapping device is as follows:
firstly, a pneumatic hammer type anode rapping device is arranged on each anode plate, pipelines are respectively arranged on the pneumatic rapping hammers, whether the pipelines are leaked or not is checked, and meanwhile, an electric appliance control part is arranged.
Secondly, when the device works, the impact force of the pneumatic knocking hammer is transmitted to the rapping anvil and the anode plate to knock off the attached dust. The time delay unit is adjusted to lead the impact force time of the pneumatic knocking hammer on each anode plate to be different, thus changing the rapping period, solving the problem of consistent rapping period and reducing secondary dust.
