Description
Technical Field
The invention relates to a loading device for dry quenching, in particular to a double-hopper loading device with lifting sleeves sealed at two sides and a working method thereof.
Background
The charging device is an indispensable component in dry quenching, and has the main functions of opening and closing a furnace cover and uniformly introducing the incandescent coke in the coke tank into the dry quenching furnace for quenching through a distributor. The conventional coke dry quenching loading device is shown in figure 1 and is arranged on a platform 1-1 at the top of the coke dry quenching furnace and mainly comprises a hopper 1-2, a dustproof cover plate 1-3, a bell 1-4, a furnace cover 1-5, a hopper trolley 1-6, a furnace cover trolley 1-7, a transmission mechanism 1-8, a track frame 1-9, a sliding support 1-10, a fixed support 1-18, a guide template 1-11 and the like.
The hopper 1-2 is arranged on the hopper trolley 1-6, the furnace cover 1-5 is arranged on the furnace cover trolley 1-7, the furnace cover trolley 1-7 and the hopper trolley 1-6 are connected together through a pin shaft and walk on a track together, and the actions of opening the furnace cover 1-5, aligning the hopper 1-2 with a dry quenching furnace mouth, removing the hopper 1-2 and closing the furnace cover 1-5 are sequentially completed under the auxiliary limit of the guide template 1-11 through driving of the electric cylinder 1-12.
Normally (in standby), the furnace cover 1-5 is covered on the dry quenching furnace mouth, and the water seal cover 1-13 on the furnace cover 1-5 is inserted into the water seal groove 1-14 of the furnace mouth to keep the pressure in the dry quenching furnace. When the elevator sends out a loading instruction, the electric cylinder 1-12 starts traction action, and the processes of lifting the furnace cover 1-5, moving the trolley (1-6 and 1-7) and aligning the hopper 1-2 with the dry quenching furnace mouth are sequentially completed. The water seal cover 1-15 arranged at the discharging opening of the hopper 1-2 falls into the water seal tank 1-14 at a low speed, so that dust at the dry quenching furnace opening is prevented from leaking to the outside during charging. When the furnace cover 1-5 is opened by starting the loading device, the butterfly valve on the dust collecting pipeline 1-16 is also automatically opened to start dust collection.
After the hopper 1-2 of the loading device is aligned with the dry quenching furnace mouth, the lifting machine starts to roll down the coke tank 1-17, the coke tank 1-17 is seated on the sliding support 1-10 on the hopper, then falls onto the fixed support 1-18 supported on the dry quenching furnace platform together with the sliding support 1-10, and the sealing skirt edge at the bottom of the coke tank 1-17 contacts with the upper mouth of the hopper 1-2 to prevent dust generated during loading from leaking to the outside. The lifting machine continues to roll down, the gate at the bottom of the coke tank starts to open coke, the limit switch arranged on the coke tank support acts when the gate at the bottom of the coke tank is completely opened, a signal for opening the gate at the bottom of the coke tank is sent out, and the time for charging and settling is determined by the timer; after the charging and settling are completed, the elevator starts to roll up the empty coke drums 1-17 in a reverse motion to that described above. When the empty coke tank 11-7 is coiled to the upper limit, the loading device starts to act reversely, the hopper 1-2 is removed, the furnace cover 1-5 is covered on the dry quenching furnace mouth, and the loading operation is completed once. After the furnace cover 1-5 is closed by the loading device, the butterfly valve on the dust collecting pipeline 1-16 is also automatically closed to stop dust collection.
The furnace cover 1-5 is opened for a short time, the influence time of the upper space pressure of the cooling chamber on the loading device is also short, and during the period, the micro negative pressure operation of the dry quenching furnace mouth can be realized by adjusting the top pressure of the pre-storing chamber, and the furnace top dust collecting system is matched, so that a large amount of dust at the furnace mouth can be basically prevented from escaping.
However, the conventional loading device has the following disadvantages:
1) The loading device is only suitable for intermittent operation of centralizing a large amount of feed materials in a short time, but is not suitable for continuous and small-amount dispersed feed materials (such as a chain bucket conveyor and the like) in a long time. Because the charging device is not provided with the pre-stored hopper, on one hand, the furnace cover and the charging hopper can not be switched in the long-time continuous feeding period, which is equivalent to the state that the dry quenching furnace is in the uncapped charging state, and the pressure system in the dry quenching furnace can be adversely affected; on the other hand, when the material quantity is small, the material cannot be layered when the material is fed in a dispersed manner through the bell, so that the randomness of the distribution is large due to the ejection effect among particles, and even distribution is difficult to realize.
2) The hopper of the loading device is only used as a material circulation channel during loading operation, and does not have the functions of pre-storing and sealing. The hopper and the furnace cover are required to be switched by using an electric cylinder (or a hydraulic cylinder, etc.) frequently so as to realize the loading or sealing working state of the furnace mouth, thereby increasing the equipment cost and the running cost.
3) The bell in the loading hopper is extremely fragile under the working condition that the abrasion is strong and the high-temperature impact is large because of long-term use, and even if the bell is integrally replaced after being damaged, the work intensity is also large, the operation time consumption is long, the requirement cannot be met by the conventional overhaul time, and the continuity of production operation is difficult to guarantee.

The working method of the double-hopper loading device with the double-side sealing of the lifting sleeve comprises the following steps:
one trolley of the double-hopper loading device is positioned at the loading position in the center of the furnace mouth, and the other trolley is positioned at the overhauling position at one side; the 2 trolley locks the position through wheel blocks, car blocks and trolley stop seats arranged on the track respectively; the initial positions of the water sealing covers in the 2 charging units are all in a lifting state, and the charging process only adjusts the charging units at the charging positions, and the specific adjustment steps are as follows:
1) The corresponding water seal cover is fallen into the water seal groove by adjusting the water seal cover lifting mechanism, and the enough water seal height is maintained;
2) The dust collecting cover is connected with the upper hopper through the soft connecting sleeve, so that dust is prevented from escaping from the dust collecting cover;
3) When no material is put into the dry quenching furnace in a standby state, the sealing surface at the lower edge of the lifting sleeve is tightly attached to the sealing surface correspondingly arranged at the outer side of the bell body of the bell, and the sealing formed by columnar materials in the upper hopper, the discharging pipe and the lower hopper is used for isolating the pre-storage chamber of the dry quenching furnace from the atmosphere;
4) When the chain bucket conveyor starts to start, the dust removing fans of the dust removing ground station connected with the dust collecting pipeline start and run at high speed at the same time, and dust collection is prepared through the dust collecting pipeline; the material enters the dust hood from the discharge opening of the chain bucket conveyor and falls into the upper hopper, the material gradually accumulates in the upper hopper due to the matched sealing effect of the lifting sleeve and the material bell, when the material level in the upper hopper reaches the material level meter, the actuating mechanism of the lifting sleeve is started, the lifting sleeve is lifted until the sealing surface at the upper edge of the lifting sleeve is tightly attached to the sealing surface of the upper sealing body of the material bell to realize the upper sealing, meanwhile, the lower sealing formed by the lower edge of the lifting sleeve and the sealing surface of the bell body of the material bell is opened, and the material in the lifting sleeve and the material discharge pipe starts to enter the lower hopper and enters the dry quenching furnace after being distributed by the material bell;
5) Calibrating the time for which the lifting sleeve and the material in the discharging pipe are completely discharged after the lower seal is opened on site, and taking the time as the delay time set by the re-action of the actuating mechanism of the lifting sleeve, namely, the actuating mechanism of the lifting sleeve acts again after the material is completely discharged, and the lifting sleeve is lowered to enable the sealing surface at the lower edge of the lifting sleeve to be closely attached to the sealing surface on the bell body of the material, so that the material in the upper hopper enters the discharging pipe and the lifting sleeve again; repeating the above actions;
6) When the upper hopper discharges materials, the height of the lifting sleeve is controlled by adjusting the stroke of the actuating mechanism of the lifting sleeve, so that the discharging speed of the upper hopper is slower than the feeding speed of the chain bucket conveyor; under the working condition, the material level in the upper hopper continues to rise until the feeding of the chain conveyor is finished, and at the moment, the dust removing fan of the ground dust removing station starts to be turned into low-speed operation;
7) After the feeding of the chain bucket conveyor is finished, the materials in the upper hopper are intermittently loaded into the dry quenching furnace along with the lifting sleeve and the discharging pipe, the material level in the upper hopper starts to slowly descend, and when the material level is lowered to the position of the material level indicator, the actuating mechanism of the lifting sleeve acts again to realize the lower sealing of the lifting sleeve; meanwhile, the dust removing fan of the dust removing ground station stops running, so that one loading working cycle is completed;
when the charging unit in the charging position needs to be overhauled, firstly, the soft connecting sleeve fastened at the top of the hopper at the upper part of the charging unit is removed, then the wheel block, the car block and the trolley stop seat are removed, and the water sealing cover is lifted by the water sealing cover lifting mechanism; and then the trolley at the loading position is moved to one side of the maintenance position by the manual trolley moving mechanism, at the moment, the other standby trolley synchronously moves to the loading position, and the moving unit entering the loading position is adjusted according to the steps 1) -7), so that a new loading working cycle is realized.
Compared with the prior art, the invention has the beneficial effects that:
1) Each charging unit has the functions of pre-storing and sealing, and a furnace cover and an electric cylinder for switching a charging hopper and the furnace cover are not needed, so that the equipment cost and the running cost are greatly reduced;
2) The upper hopper, the discharging pipe and the lower hopper are lined with heat insulation materials, so that the heat loss is reduced compared with the hopper of the conventional dry quenching loading device, and the heat efficiency of the dry quenching furnace is improved;
3) The dust hood and the upper hopper are sealed by adopting an integral soft connecting sleeve, so that the skirt edge between the dust hood and the upper hopper is sealed more tightly than the skirt edge between the conventional coke dry quenching tank and the conventional coke dry quenching hopper, and the dust escape at the dust hood is thoroughly eliminated;
4) When the dry quenching furnace is charged, the upper part between the upper edge of the lifting sleeve and the sealing body is sealed completely to isolate the influence of the material in the upper hopper on the material to be charged into the dry quenching furnace, the material to be charged into the dry quenching furnace is basically equal each time, the bottom material flow can be uniformly and controllably realized by adjusting the height of the lifting sleeve through the actuating mechanism during charging, the combination of the three factors is more beneficial to realizing uniform feeding and uniform distribution, the kinetic energy of the material falling into the dry quenching furnace is effectively buffered, the segregation of the material is reduced, and the possibility of fragmentation of the material is reduced;
5) Under the working condition of loading or non-loading, a mechanical sealing surface and a section of sealing formed by a higher material column are always arranged between the furnace mouth and the external atmosphere, so that the furnace mouth and the external atmosphere are completely isolated, the leakage resistance between the pre-chamber of the dry quenching furnace and the atmosphere is increased, and the influence of the top pressure of the pre-chamber on loading is eliminated to a great extent;
6) The sectional area of the discharging pipe is far smaller than the average sectional area of the upper hopper, so that the material level in the upper hopper descends more slowly under the condition of the same material flow, secondary dust in the descending process is greatly reduced, and the load of the dust removing ground station is reduced; the blanking height of the head part of the chain bucket conveyor is gradually reduced as the material level in the upper hopper is gradually increased, so that dust and cloth segregation of the conveyor in the discharging process are also gradually reduced;
7) According to the invention, 2 independent charging units are arranged, so that the on-line standby and switching are realized, the rapid switching can be completed by utilizing the feeding gap, and the operation is simple and feasible, thereby ensuring the continuity of production operation; the equipment does not need to be maintained on line but enters a maintenance position on one side for maintenance, so that the labor intensity of maintenance personnel is reduced, and the working environment is improved;
8) Besides the automatic control of the lifting function of the lifting sleeve, other lifting mechanisms such as a water seal cover lifting mechanism and a manual vehicle moving mechanism are simple manual operation, the power source is reduced to the maximum bearing degree, the failure rate of the mechanism is reduced, the running reliability of the device is improved, and meanwhile, the equipment cost and the running cost of the device are reduced.
