Abstract

The utility model discloses a safety interlocked device for a vulcanizing boiler, comprising a vulcanizing boiler body, a boiler cover positioned on the end part of the vulcanizing boiler body, a sealed clamping hoop for plugging the combining site of the vulcanizing boiler body and the boiler cover and an air pressure sealed ring positioned in the combining site of the vulcanizing boiler body and the boiler cover. A first hydraulic cylinder for opening the boiler cover is arranged between the vulcanizing boiler body and the boiler cover. A second hydraulic cylinder for opening the sealed clamping hoop is also arranged on the sealed clamping hoop. A control device for controlling the first hydraulic cylinder and the second hydraulic cylinder moving is arranged. The structure completely replaces the manual operation and effectively controls the safety and reliability of the industrial process of vulcanizing by the control device.

Description

The vulcanizing tank safety interlocking
Affiliated field
The utility model relates to a kind of vulcanizing tank, relates in particular to a kind of safety device of vulcanizing tank.
Background technology
Horizontal vulcanizer is a fast opening type pressure container, and according to " safe technology of pressure vessel procuratorial work rules " requirement, fast opening type pressure container is answered the design safety interlock and had following function: 1. when quick operating valve reaches predetermined closed position can booste operation; 2. work as the pressure vessel internal pressure and discharge fully, safety interlocking can be opened quick operating valve after throwing off; 3. have the warning function synchronous with above-mentioned functions.Traditional vulcanizing tank safety interlocking adopts manually control mostly, and a spanner drives ball valve and latch simultaneously.Close ball valve during admission, latch is lived jar door lock.Open wide ball valve during steam discharge, if jar in have pressure then ball valve report to the police, no longer outwards open a jar door during steam discharge again until ball valve.This apparatus structure is simple, but because by experiential operating (seeing that ball valve emits vapour, Pressure gauge indicated value in zero actual jar pressure to be arranged still), poor stability might cause accident.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of process automation, reduces the vulcanizing tank safety interlocking of human factor influence.
For achieving the above object, the technical solution of the utility model is: the vulcanizing tank safety interlocking comprises the sulfuration tank body, is positioned at the cover of vulcanizing tank end of body, the sealing clip that is used for shutoff sulfuration tank body and cover joint portion, be positioned at the pressurized seal circle of sulfuration tank body and cover joint portion, be provided with first hydraulic cylinder that can be used for opening cover between described sulfuration tank body and the cover, also be provided with second hydraulic cylinder that is used to open the envelope clip on the sealing clip, also have the control device of control first hydraulic cylinder and the motion of second hydraulic cylinder.
As a kind of improvement, described control device comprises switch board, sends the position switch that first hydraulic cylinder opens and closes signal to switch board, sends the position switch that second hydraulic cylinder opens and closes signal to switch board, by the Hydraulic Station and the air pressure station of switch board control.
Owing to adopt technique scheme, the vulcanizing tank safety interlocking comprises the sulfuration tank body, is positioned at the cover of vulcanizing tank end of body, the sealing clip that is used for shutoff sulfuration tank body and cover joint portion, be positioned at the pressurized seal circle of sulfuration tank body and cover joint portion, be provided with first hydraulic cylinder that can be used for opening cover between described sulfuration tank body and the cover, also be provided with second hydraulic cylinder that is used to open the envelope clip on the sealing clip, also have the control device of control first hydraulic cylinder and the motion of second hydraulic cylinder; This structure has substituted manually-operated fully, and the safe and reliable of vulcanization process can be effectively controlled in the control by control device.
Description of drawings
Accompanying drawing 1 is the schematic diagram of the utility model embodiment.
Accompanying drawing 2 is operation principle schematic diagrames of the utility model embodiment.
The specific embodiment
Shown in accompanying drawing 1, accompanying drawing 2, the vulcanizing tank safety interlocking comprises sulfuration tank body 1, is positioned at the cover 2 of sulfuration tank body 1 end, the sealing clip 3 that is used for shutoff sulfuration tank body 1 and cover 2 joint portions, be positioned at the pressurized seal circle of sulfuration tank body 1 and cover 2 joint portions, be provided with first hydraulic cylinder 4 that can be used for opening cover 2 between described sulfuration tank body 1 and the cover 2, also be provided with second hydraulic cylinder 6 that is used to open envelope clip 3 on the sealing clip 3, also have the control device of control first hydraulic cylinder 4 and 6 motions of second hydraulic cylinder.Described control device comprises switch board 8, sends the position switch 41,42 that first hydraulic cylinder 4 opens and closes signal to switch board 8, sends the position switch 61,62 that second hydraulic cylinder 6 opens and closes signal to switch board 8, by the Hydraulic Station 7 and the air pressure station 9 of switch board 8 controls.
Cover 2 and sealing clip 3 open and close to be finished by hydraulic jack, and cover 2 seals and adopts the pressurized seal circles, and travel switch control jar door cover 2 opens and closes with sealing clip 3, and pressure controller detects a jar interior residual pressure.Interlocking principle of the present utility model is as follows: at closing time, when hydraulic jack promoted a jar door and is closed to the precalculated position, travel switch 42 actions were posted a letter, and sealed clip 3 then and screwed and put in place, and the air inlet of pressurized seal circle is posted a letter in travel switch 61 actions.After this close the steam discharge magnetic valve, open the admission magnetic valve, beginning booste operation in jar.When opening the door, steam is discharged earlier in jar.When jar internal pressure during less than 0.01MPa, the pressure controller action is posted a letter, and release in the pressurized seal circle is discharged jar interior steam fully, seals clip 3 and cover 2 unlatchings then.In the course of action, each indicator lamp is corresponding lights indication.Certainly, the travel switch position is adjusted pressure switch and is made its operating pressure less than 0.01MPa in the time of at first should adjusting each travel switch and make cover 2 close, seal clip 3 fully to screw fully.When cover 2 is not closed fully, when sealing clip 3 did not screw fully, travel switch was failure to actuate and is posted a letter, and admission and steam discharge magnetic valve all are failure to actuate, and equipment communicates with atmosphere, jar interior no pressure.Equipment is finished a course of work, in jar pressure (pressure is greater than 0.01MPa) is arranged, and pressure controller is failure to actuate and is posted a letter, and first hydraulic cylinder 4 and second hydraulic cylinder 6 all are failure to actuate.Simultaneously, two contact tandem workings of each travel switch and periodic replacement can not cause accident to take place even travel switch damages yet.This shows that the utility model meets " safe technology of pressure vessel procuratorial work rules " requirement fully, and process automation, has reduced artificial factor, reduce operator's labour intensity, meet the Electromechanical Design principle.
