Abstract
The utility model relates to an emergence shutdown device for detecting fracture and leakage of a filter bag of purification equipment, which belongs to the technical field of dust cleaning equipment and comprises a rapidly-closed shelf communicated with a flow channel. One side of the rapid closed shelf is hinged with a door frame pole which is fixedly connected with a rapidly-closed door tending to close the flow channel under the action of an elastic piece; an electromagnet is arranged at one end of the door frame pole, far away from the rapidly-closed door; and when an iron core of the electromagnet pushes against the door frame pole, the rapidly-closed door overcomes the elastic piece, and is located at a position for opening the flow channel. When a filter bag is fractured, the filtering resistance of the filter bag is reduced, the flow rate is increased, and a detecting element drives the electromagnet to act by a control circuit, so that the rapidly-closed door is closed in emergency under the action of the elastic piece, and an air flow passage leading to the fractured filter bag is cut off, thereby keeping a dust catcher to still work normally, preventing accidents from happening, and avoiding economic loss due to emergency shutdown. During shutdown for maintenance, the filter bag is replaced.
Description
Technical field
The utility model relates to a kind of protector, and the run-down detection emergency shutdown device of especially a kind of cleaning equipment filter bag belongs to the cleaner technical field.
Background technology
When the coal gas of raw coke oven gas pipe input gets into the raw coke oven gas chamber, the dust natural subsidence that particle is bigger and get into ash bucket, the less dust of particle rises with coal gas.When filter bag, dust is surperficial in filter bag by detention, thereby coal gas is purified.
Because the filtration, purification of this type of cleaning equipment is accomplished by many filter bags; Therefore when one of them bag breakage or when coming off, a large amount of raw coke oven gas will directly get into clean room, make the deduster operational failure; The result causes must stopping production to shut down implementing maintenance, causes bigger economic loss.
The utility model content
The purpose of the utility model is: to the deficiency that above-mentioned prior art exists, propose a kind of can working as and the run-down detection emergency shutdown device of cleaning equipment filter bag that filter bag in time plays the security protection effect when run-down occurs.
In order to reach above purpose, the run-down detection emergency shutdown device of the cleaning equipment filter bag of the utility model comprises the fast closed shelves that is communicated with gas channel, the hinged door frame bar of a side of said fast closed shelves; Be fixed with on the said door frame bar under the elastic component effect, be tending towards sealing gas channel close door soon; Said door frame bar is equipped with electromagnet away from an end that closes door soon; When the iron core of said electromagnet pushed against the door frame bar, the said door that closes soon overcame elastic component, is in and opens the gas channel position.
Therefore, when the deduster operate as normal, because each filter bag filtration resistance of deduster is consistent, the air-flow output speed is consistent, and electromagnet is in maintenance and closes an enable possition state soon.When a certain filter bag broke, the filtration resistance of this bag reduced, and flow velocity increases; Detection means is ordered about the electromagnet action through control circuit; Close door emergency cut-off under the effect of elastic component soon thereby make, cut off to lead to the current path of this damaged filter bag, thereby keep the deduster still can operate as normal; Avoid accident to take place, avoided because the economic loss that emergency cutoff causes.When treating shutdown maintenance, again this filter bag is changed.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Embodiment one
The run-down detection emergency shutdown device of the cleaning equipment filter bag of present embodiment is as depicted in figs. 1 and 2; Comprise the fast closed shelves 3 that is communicated with gas channel; The hinged door frame bar 7 of one side of fast closed shelves 3; Be fixed with on the door frame bar 7 what spring 5 effect was tending towards sealing gas channel down and close door 4 soon, an end hook of this spring hangs over and closes a middle part of 4 soon, and the other end is hooked on the fast closed shelves 3.Door frame bar 7 is equipped with electromagnet 2 away from an end that closes door soon, and fast closed shelves 3 is equipped with signal generator 1 with the gas channel place of connection.6 is deduster winding-up mouths among the figure.
Under the normal condition, the iron core of electromagnet 2 is in shown position, and the lower end of pushing and pressing door frame bar 7 is closed door 4 soon and overcome acting force of the spring, is in and opens the gas channel position.Finding the y bag when the signal generator that with the flowing gas is rotary power descends because of the gas-flow resistance of breaking; Gas flow rate increases; The signal generator rotating speed increases the signal increment control electromagnet of output to be return, and closes door quick closedown under the effect of spring soon, cuts off y bag gas channel; Thereby the maintenance system continues operate as normal, avoids breaking down.
When treating the entire equipment overhaul, this bag changed get final product, can avoid like this because the economic loss that emergency cutoff causes.
Claims (3)
1. the run-down detection emergency shutdown device of cleaning equipment filter bag is characterized in that: comprise the fast closed shelves that is communicated with gas channel, the hinged door frame bar of a side of said fast closed shelves; Be fixed with on the said door frame bar under the elastic component effect, be tending towards sealing gas channel close door soon; Said door frame bar is equipped with electromagnet away from an end that closes door soon; When the iron core of said electromagnet pushed against the door frame bar, the said door that closes soon overcame elastic component, is in and opens the gas channel position.
