Abstract

The utility model relates to a hydraulic fire door capable of turning over a furnace lid, which comprises a fire door, a furnace lid, a cantilever, and an oil cylinder. The utility model is characterized in that the oil cylinder is fixedly installed on one side of the fire door; the cantilever is connected with the oil cylinder; the end part of the cantilever is connected with the furnace lid through a leading screw; a positioning rotating device is fixedly installed at the connecting point between the end of the cantilever and the leading screw on the furnace lid. Because a positioning rotating device is additionally arranged at the connecting point between a furnace lid of a fire door and a cantilever existing in the prior art, which leads the furnace lid to rotate along the axial direction of the cantilever after being opened, the utility model has the advantages of simple and compact structure, easy machining, convenient operation, easy maintenance, low labor intensity, high gas yield, and high work efficiency.

Description

The hydraulic pressure fire door of turning bell

The utility model belongs to fertilizer industry producer gas generator parts, specifically is a kind of hydraulic pressure fire door of turning bell.

The bell of the hydraulic pressure fire door of present fertilizer industry producer gas generator, in the outfit of producer gas generator, according to industrial requirements, its stopping property will be got well, therefore lock packing is housed on bell, original filler is after ineffective, need service worker after blowing out, to pull down bell with anchor clamps, again bell is installed on the cantilever of fire door after changing filler, because of filler belongs to attrition component, thus in practical work process, must not stop repeat above-mentioned work, so not only strengthened working strength of workers, and directly influenced the gas yield of gas furnace, increased manufacturing cost.

The purpose of this utility model is to overcome above-mentioned deficiency, existing connecting mode is improved, provide a kind of simple and compact for structure, be easy to processing, easy to operate, easy maintenance reduces labour intensity, increases gas yield, improves the hydraulic pressure fire door of the turning bell of work efficiency.

The utility model is achieved through the following technical solutions:

It is a kind of hydraulic pressure fire door of turning bell, comprise fire door, bell, cantilever and oil cylinder, the side fixed installation oil cylinder of fire door, cantilever connects with oil cylinder, end at cantilever connects bell with leading screw, and the connection place of leading screw fixed installation position rotating dress is wanted on cantilever end and bell.

Described position rotating device comprises steady brace, stage clip, axle sleeve and rotating shaft, shaft set is in axle sleeve, the end of ring rotating shaft is processed with chute, in chute, be processed with pin-and-hole, be processed with through hole on the axle sleeve of respective pin hole, fixedly mount location key seat on the through hole, steady brace is installed in the key seat, suit stage clip on the steady brace, stage clip is located by nut.

Be processed with an above pin-and-hole in the described rotating shaft.

In a certain angle between the pin-and-hole of processing in the described rotating shaft.

The utility model has compared with prior art been adorned the position rotating device owing to increase in the connection place of the bell of fire door and cantilever, makes the bell can be along the cantilever axial rotation, so have the following advantages after unlatching:

1, simple and compact for structure, be easy to processing.

2, easy to operate, easy maintenance.

3, reduce labour intensity, increase gas yield, raising work efficiency.

Describe in further detail below in conjunction with accompanying drawing:

Fig. 1: the utility model embodiment mounting structure synoptic diagram.

Fig. 2: the utility model embodiment position rotating apparatus structure synoptic diagram.

Among the figure: 1 bell, 2 is adjusted handwheel, 3 position rotating devices, 4 cantilevers, 5 hydro-cylinders, 6 fire doors, 7 axle sleeves, 8 rotating shafts, 9 chutes, 10 pin-and-holes, 11 steady braces, 12 stage clips, 13 nuts, 14 key seats

As shown in Figure 1, position rotating device 3 is fixedly mounted on the end of cantilever 4, this moment, steady brace 5 was stuck in the pin-and-hole 4 of rotating shaft 2, bell 1 is located towards the below, the same with common bell schedule of operation by hydro-cylinder 5 and adjust handwheel 2 and carry out the unlatching of bell 1 and fire door 6 or close, when the damage of the lock packing in the bell 1 is bad down to sealing, open bells 1 by hydro-cylinder 5 and adjustment handwheel 2, rotating cantilever 4 then makes bell to fire door one side, with the button that draws of carrying the steady brace 11 that is installed in the key seat on the axle sleeve 7 14 on hand, then steady brace 11 reactive force that overcomes stage clip 12 leaves the pin-and-hole 10 in rotating shaft 8 chutes 9, rotate bell 1 again, the rotating shaft 8 that links with bell 1 is axially rotated down the spacing of steady brace 11 along axle sleeve 7, in a certain angle because of 11 of pin-and-holes in the chute 9, turn to inside-out so work as bell 1, in the time of can conveniently changing the outfit the position of lock packing, the steady brace 11 that slides along chute 9 just in time sticks into another pin-and-hole 10, makes bell 1 location, with the filler that changes the outfit; After filler replacement finishes, use portable the steady brace 11 on the axle sleeve 7 again, rotate bell 1 with hand bell 1 is resetted, get final product according to normal schedule of operation again.

The lock packing that the utility model can be in not blowing out, damage on the bell 1 under changing fast under the situation of bell 1 under needn't dismantling, promptly alleviated the higher labour intensity that is caused because of demolition, installation bell 1, simultaneously because of can under the situation of not blowing out, just carrying out changing the outfit of lock packing fast, saved a large amount of time, so also improved the output of coal gas simultaneously, increased benefit.
