Description

A kind of ash locking device

Technical field

The utility model relates to a kind of grey locking devices, and in particular to a kind of novel ash locking device belongs to coalification construction equipment skill Art field.

Background technique

Ash lock is an equipment being widely used in above coal chemical industry gasification furnace, by outlet valve, inlet valve Door and container composition, main function are the ashes by gasification furnace burning completion to discharge.

Currently, widely used ash locking device, structure is as shown in Figure 1, be divided into upper valve, lower valve and container three parts group At, due to the direction of upper threshold switch and lower threshold switch be all it is vertical, valve rod is vertically to run, the valve rod of upper lower valve and connection All inside ash lock container, executing agency when valve event, needs through connecting shaft, to drive axis outside ash lock Valve rod movement inside ash lock, this structure of ash lock determine that ash locks valve and lower valve and can only use a valve, Stringenter occasion is required to medium cutting, if can be safer using bivalve cutting, but this structure of ash lock be made A valve can only be used at upper lower valve.

The course of work of ash lock is that ash is locked progress pressurising and stops filling when pressure reaches pressure identical with gasification furnace Pressure, then opens upper valve, and ash is packed into ash lock, ash is then shut off and locks valve, to depressurizing in ash lock, when pressure reduction to certain journey After degree, ash lock lower valve is opened, ash is discharged in lower part equipment, after ash is unsnatched, closed ash lock lower valve, just complete a job Period.

It can be seen that ash by the course of work of ash lock and lock the effect that lower valve is responsible for cutting isolation ash, also undertake The effect of cutting separation gas, therefore, ash locks lower valve and allows for the effect for accomplishing thoroughly to separate, and cannot have leakage.

In practical applications, due to the influence of dust, valve is caused to fit badly amount of leakage often, is lacked to make up this It falls into, executing agency, as power, pushes valve core movement, since the force ratio of spool is larger, valve using the hydraulic oil of 7Mpa Door is easy damage.

In addition, the valve rod and transmission mechanism due to above issuing all in ash lock, if there is problem, are needed ash lock disassembly It places under repair, since ash locks the valve rod of lower valve and executes linking axes all operations in ash is locked of structure, and the environment in ash lock Always changing, the drive mechanism for locking lower valve to ash is affected, and be easy to cause these parts damages, adds, if closed not Sternly, ash lock valve or lower valve can repeated multiple times switch, next process could be executed until closing tight not leak.This knot of ash lock Being configured to ash, to lock lower valve failure rate higher.No matter upper valve or lower valve, if necessary to repair when, will by ash lock remove into Row maintenance, this work is cumbersome and time consuming, and maintenance difficulty is very big.

Therefore it provides a kind of more durable, the service life is longer, and easy to maintenance, the low grey locking device of failure rate just becomes this Technical field technical problem urgently to be solved.

Specific embodiment

Comparative example 1

As shown in Figure 1, for the structural schematic diagram of the grey locking device in this comparative example, wherein 1 is ash lock container, and 2 be ash lock Upper valve core, 3 be executing agency, and 4 be valve rod, and 5 be valve seat, and 6 lock lower valve core for ash, and 7 be the transaxle in ash lock, under 8 are Valve valve rod.

Existing ash locking device, including ash lock container 1, ash lock valve core 2, executing agency 3, valve rod 4, valve seat 5, ash lock Lower valve core 6, ash lock in transaxle 7, lower valve valve rod 8；It is made of upper lower valve and container three parts, and ash locks valve core 2, Ash lock lower valve core 3 switch direction be all it is vertical, upper valve valve rod 4 and lower valve valve rod 8 are vertically to run, and upper valve Valve rod 4 and lower valve valve rod 8 are arranged at the inside of ash lock container 1, and there are two executing agencies 3, are respectively positioned on the outside of ash lock, work as valve When door movement, need to drive the rotation of the swing arm of ash lock the inside, the swing arm rotation of ash lock the inside by the transaxle 7 in ash lock Turn to drive moving up and down for upper and lower conical valve stem, the transaxle 7 in ash lock is the tie point that ash locks inside and outside executing agency, the connection Point is a rotary shaft, and to drive the movement of the valve rod inside ash lock, ash locks the upper valve valve rod 4 and lower valve valve rod 8 of upper and lower cone valve Respectively with ash lock in ash lock valve core 2 and ash lock under valve core 6 be connected, the switch direction of upper conical valve and lower cone valve be all to Upper movement is to open valve, and moving downward is to close valve, and the upper surface of upper conical valve is to be connected to gasification furnace, is opened when upper conical valve When, the ash in gasification furnace will lock the gap between valve core 2 and valve seat from ash and enter in ash lock, when ash locks lower valve valve When core 6 is opened, ash can lock lower gap discharge ash lock between valve core 6 and valve seat, the course of work of grey locking device from ash It is when ash locks cone valve and lower cone valve all in closed state, to be locked to ash and carry out pressurising, the pressure and gasification in ash lock It when the pressure of furnace is identical, opens ash and locks cone valve, ash is discharged in ash lock, upper conical valve is then shut off, ash lock is let out Pressure, when pressure drop to a certain extent after, open ash and lock lower cone valve, ash is discharged to ash and is locked in following equipment, lower cone is then shut off Valve just completes a cycle period.

It can be seen that the upper valve of grey locking device by the course of work of grey locking device and lower valve be responsible for cutting isolation ash Effect is also responsible for the effect of cutting separation gas, and therefore, ash locks lower valve and allows for the effect for accomplishing thoroughly to separate, no There can be leakage.In practical applications, since the influence of dust causes valve to have amount of leakage.In order to make up this defect, machine is executed Structure 3, as power, pushes ash to lock valve core 2 and the lower valve core 6 of ash lock and moves, since ash is locked using the hydraulic oil of 7Mpa Valve core 2 and ash are locked lower valve core 6 and are acted under the action of hydraulic than very fast, along with hydraulic coupling is bigger, ash are caused to lock The spool of lower valve clashes with valve seat, therefore valve is easily damaged.Due to valve executing agency some ash lock hold The inside of device 1, needs when repairing to remove on ash lock and repairs, this work is cumbersome and time consuming, and maintenance difficulty is very big.
