adjusting the pressure in the kiln to be micro-positive pressure;

hoisting the old charging hole brick by using charging hole brick hoisting equipment, moving the old charging hole brick to a set position, and simultaneously placing the flame isolating preheating plate 3 at the original brick hole to plug the charging hole;

hoisting a new charging hole brick by using the charging hole brick hoisting equipment, abutting the new charging hole brick against the flame-isolated preheating plate 3, fixing the new charging hole brick, and preheating the new charging hole brick;

measuring the temperature of the new charging hole brick, preheating the new charging hole brick for a set time after the temperature of the new charging hole brick is raised to the temperature of the old brick, removing the flame isolating preheating plate 3, and hermetically installing the new charging hole brick in the charging hole; and the temperature measuring position of the new charging hole brick corresponds to the temperature measuring position of the old charging hole brick.

According to the invention, the charging hole brick hoisting equipment is used, the old charging hole brick is replaced by the new charging hole brick, and the new charging hole brick and the old charging hole brick respectively correspond to the charging machines with different design parameters, so that the model of the charging machine is replaced under the condition of no shutdown in continuous production, the requirements of production and process stability are met, and the production flexibility is improved.

Generally, a charging hole is formed in the rear wall of the kiln, and a charging hole brick is installed on the charging hole. Specifically, referring to fig. 5, a fixed steel frame 4 is manufactured, an old charging hole brick or a new charging hole brick is embedded in an inner frame of the fixed steel frame 4, and when the charging hole brick is replaced, the fixed steel frame 4 is hoisted by using charging hole brick hoisting equipment, so that the old charging hole brick or the new charging hole brick is moved. Conventionally, a hoisting ring is installed on the fixed steel frame 4, and correspondingly, referring to fig. 3, the charging opening brick hoisting equipment mainly comprises a moving support 71 and a hoisting rod 72, the hoisting rod 72 is erected on the moving support 71, a hook is arranged at the front end of the hoisting rod 72, so that the front end of the hoisting rod 72 is hooked on the hoisting ring on the fixed steel frame 4, and a pulley is arranged at the bottom of the moving support 71, so as to move along with the moving support 71, so as to drive the fixed steel frame 4 to move, and further move an old charging opening brick or a new charging opening brick.

And, be provided with fixed knot on the back wall of kiln constructs, fixed knot constructs and is used for fixing fixed steel frame 4 on the back wall, simultaneously, and the design has the depression bar, and the depression bar is installed on fixed steel frame 4 to support with old charge door brick or new charge door brick and lean on, fasten depression bar and fixed steel frame 4 on fixed knot constructs jointly through the bolt.

In order to ensure the stability of the movement of the new charging hole brick, referring to fig. 4, a fixed guide rod 5 is manufactured, and the fixed guide rod 5 is used to be connected with a fixed steel frame 4. Specifically, a fastener may be disposed at the front end of the fixing guide rod 5, and in the embodiment shown in fig. 4, the front end of the fixing guide rod 5 is a saw-toothed structure and can be engaged with the edge of the fixing steel frame 4. Usually, select two fixed guide bars 5, respectively with the edge joint of fixed steelframe 4 left and right sides, at the in-process that removes new charge door brick, keep two relative positions between the fixed guide bar 5, can remote fixed new charge door brick, remove the in-process at new charge door brick and avoid controlling rocking, improve the security that the in-process was changed to the charge door brick. Furthermore, a connecting rod, for example, a connecting rod with a threaded structure at both ends, may be disposed between the two fixed guide rods 5, so that both ends of the connecting rod are respectively in threaded connection with one fixed guide rod 5, and more than two connecting rods may be used, thereby ensuring the relative position between the two fixed guide rods 5 and enabling the fixed guide rods 5 to have better firmness; alternatively, the connecting rod may be pin-connected to the fixed guide rod 5.

In order to prevent flame in the kiln from being sprayed out, before the old feed inlet brick is removed, the pressure in the kiln can be adjusted to be micro-positive pressure, and the pressure is normally 10-20 Pa.

Further, after demolising old charge door brick, need preheat the board shutoff charge door with isolated flame, on the one hand, can further prevent flame blowout in the kiln, on the other hand, after leaning on new charge door brick on isolated flame preheating plate, can utilize the temperature in the kiln to preheat new charge door brick, make new charge door brick can heat up to the old brick temperature of record before old charge door brick demolishs. For the temperature measurement of the old charging hole brick 1, the temperature measurement position can be selected within the range of 5-10cm away from the edge of the old charging hole brick 1 for temperature measurement; correspondingly, for a new feed block, temperature measurements are also required at the same location corresponding thereto.

The flame-isolating preheating plate can be made of refractory materials such as ceramic fiber plates and the like according to the size of the feed inlet, and is generally larger than the feed inlet; the thickness of the flame-isolating preheating plate can be 10-20 mm, preferably 12.5mm, certain strength is kept at high temperature, and the preheating effect of a new feed opening brick is prevented from being influenced by the fragmentation of a ceramic fiber plate in the preheating process.

When the temperature of the new charging hole brick is raised to the temperature of the old brick, the new charging hole brick needs to be preheated for 5-10 days, then the isolated flame preheating plate 3 can be removed, after the isolated flame preheating plate 3 is removed, the wall heat-insulating material and the charging hole brick seal are manufactured again, for example, heat-insulating refractory mortar is adopted as the heat-insulating material, and glass fiber sealing cotton is adopted as the sealing material. When the flame-isolating preheating plate 3 is dismounted, the time needs to be shortened as much as possible, and the temperature difference before and after mounting is reduced.

In addition, referring to fig. 2, a guide rail 6 is generally arranged on the ground for moving the charging machine, since the central point of the guide rail 6 corresponds to the central point of the old charging hole brick installed in a cold state, after the old charging hole brick is heated by the flame of the kiln, the wall body may deform to some extent due to the non-uniformity of thermal expansion after the kiln is heated, so that the central point of the old charging hole brick may change; therefore, before the old charging hole brick is dismantled, the position of the guide rail 6 needs to be readjusted and set according to the central point of the old charging hole brick at the new position, and then the position of the new charging hole brick is adjusted according to the adjusted position of the guide rail 6, so that the center of the new charging hole brick corresponds to the central point of the guide rail 6, even if the feeding machine port on the new charging hole brick is positioned at the central position. Wherein, can set up position control structure, for example set up structures such as jackscrew or bolt in fixed steelframe 4's side all around, promote fixed steelframe 4 through rotatory jackscrew or bolt and remove to adjust the position of new charge door brick.

For better understanding of the technical solution of the present invention, the following description is made with reference to fig. 1 to 6 and the relatively comprehensive technical features.
