Description

Technical Field

[0001] The invention relates to the technical field of high-temperature furnace preparation, in particular to a high-temperature furnace lining structure for refractory hollow balls. Background Art

[0002] High temperature furnace, also called muffle furnace, is a national standard energy-saving cycle operation electric furnace, mainly used for normalizing, quenching, annealing and other heat treatment of alloy steel products and various metal parts. It is a manufacturing tool for various mechanical equipment in the industrial society.

[0003] The refractory hollow ball is a hollow spherical bulk refractory material. Common ones include alumina hollow balls and zirconia hollow balls. They are not only hard in material but also resistant to high temperatures. They can be used as raw materials for making thermal insulation products or directly used as the thermal insulation layer of high-temperature kilns in bulk. In modern industry, the use of refractory hollow balls is increasing day by day, and the manufacturing environment of refractory hollow balls requires a high temperature state, so the use of high-temperature furnaces meets the needs of refractory hollow balls.

[0004] The Chinese patent authorization announcement number is CN210773436U, and the authorization announcement date is June 16, 2020. It discloses a high-temperature plate for the lining of an ultra-high temperature furnace that is easy to disassemble, including a furnace shell, the side wall of the furnace shell is fixedly connected with a fixed track, the top of the fixed track is slidably connected with an inner lining plate, the side wall of the inner lining plate is fixedly connected with a handle, the top of the inner lining plate is slidably connected with a locking box body, the locking box body is fixedly connected to the side wall of the furnace shell, the interior of the locking box body is provided with a rectangular groove, a locking device is provided in the rectangular groove, a card slot matching the locking device is provided on the inner lining plate, the side wall of the fixed track is provided with a cylindrical groove, and a bolt is threadedly connected in the cylindrical groove, the bolt passes through the fixed track and the side wall of the furnace shell and is threadedly connected with the furnace shell, and the nut of the bolt is against the inner wall of the cylindrical groove. The disadvantage of this technical solution is that when it is used, the inner lining plate is quickly clamped by the locking mechanism and the fixed track, and then production work can be carried out. However, the ultra-high temperature furnace here is not equipped with a structure that allows the objects in the furnace shell to roll smoothly. That is, when high-temperature manufacturing is carried out in the furnace shell, the objects are often in a stationary state, which affects the balanced heating of the objects. One end of the objects may be heated and melted in a high-temperature state, while the other end is not processed in a high-temperature state. Especially for spherical structures, the unbalanced heating state will directly affect the shape of the structure.

[0005] In summary, a design can be set up to allow high temperature manufactured structures to perform evenly heated work. Summary of the invention

[0006] The present invention aims to overcome the drawback of the prior art that workpieces remain stationary at high temperatures, and provides a high-temperature furnace lining structure for refractory hollow balls that allows workpieces to be manufactured at high temperatures while rotating.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A high-temperature furnace lining structure for refractory hollow balls comprises a high-temperature furnace body, a top cover and a bottom plate, wherein the top cover is placed at the top end of the high-temperature furnace body, and the top cover is detachably connected to the high-temperature furnace body, the bottom plate is placed at the bottom end of the high-temperature furnace body, and the bottom plate is connected to the high-temperature furnace body, a roller, an air pump and a plurality of rolling shafts are installed on the high-temperature furnace body, the roller is sleeved in the high-temperature furnace body, and the plurality of rolling shafts are distributed in a ring shape with the roller as the center, the top end of the roller and the top end of the rolling shaft are both detachably connected to the top cover, the bottom end of the roller and the bottom end of the rolling shaft are both detachably connected to the bottom plate, a plurality of through holes are provided on the rolling shaft, and the plurality of through holes are evenly distributed from the top end to the bottom end of the rolling shaft, an air outlet pipe is installed on the air pump, one end of the air outlet pipe is connected to the air pump, and the other end of the air outlet pipe is connected to the through hole.

[0008] This design can be installed into a high-temperature furnace structure through the high-temperature furnace body, the top cover and the bottom plate, so that the top cover is placed on the top of the high-temperature furnace body, and the bottom plate is placed on the bottom of the high-temperature furnace body. The bottom plate is connected to the high-temperature furnace body, and the top cover is detachably connected to the high-temperature furnace body. Then, the bottom plate can have a sealing effect on the bottom of the high-temperature furnace body, thereby preventing objects (generally referring to refractory hollow balls) and components in the high-temperature furnace body from falling out through the bottom of the high-temperature furnace body. The bottom of the high-temperature furnace body can be smoothly opened and closed through the installation and disassembly of the top cover, which facilitates the placement of foreign objects and prevents objects in the high-temperature furnace body from falling out. Of course, the high-temperature furnace body is equipped with a roller, an air pump and several rolling shafts.

Of course, the rolling shaft needs to be distributed on the insulating cylinder, so that the rotation of the roller can contact the rolling shaft, which not only drives the rolling shaft to rotate, so as to avoid the insulating cylinder being damaged by the rotation of the roller, but also allows the roller to rotate stably under the support effect, that is, the object in the roller is subjected to high-temperature processing in a stable rotating state.

[0014] Preferably, the insulation cylinder is provided with a plurality of limit grooves, which are distributed in a ring shape with the center of the insulation cylinder as the base point, the rolling shaft corresponds to the limit grooves one by one, and the exhaust holes are placed at the limit grooves.

Not only that, a mounting groove is provided on the chassis, a motor is installed in the mounting groove, and a motor shaft is installed on the motor, so the bottom of the closed drum can be connected to the motor shaft, so the work of the motor is to make the motor shaft rotate, and the drum will rotate under the drive of the motor shaft, and the object in the drum is driven to rotate, that is, high temperature processing is performed in a rotating state.

[0016] Preferably, a switch assembly is installed on the chassis, and the air pump and the motor are electrically connected to the switch assembly.

Of course, the position of the bottom of the rotating plate here needs to correspond to the position of the block, and the block is placed between the rotating plate and the exhaust hole, so that the outside gas cannot automatically blow into the exhaust hole through the vent when the rotating plate is blocked, and then blow into the through hole through the exhaust hole. Of course, when the air pump is working, the gas generated can be placed in the outlet pipe, cavity and exhaust hole (it goes without saying that there is gas in the drum). When the gas is excessive, the air pressure will exert pressure on the turn plate, and the turn plate will flip under the force to open the vent, so that the gas can be smoothly sprayed out from the vent. There will be not only room temperature gas generated by the air pump, but also high temperature gas in the environment where the object is heated. This can prevent the high-temperature furnace body from exploding under the influence of air pressure because the gas cannot be discharged smoothly.

The high-temperature furnace body 1 is provided with a plurality of vents 22, and the vents 22 correspond to the exhaust holes 21 one by one. A rotating plate 23 and a stopper 24 are installed at the vents 22, and the top of the rotating plate 23 is placed at the top of the vent 22, and the stopper 24 is placed at the bottom of the vent 22. The top of the rotating plate 23 is detachably connected to the high-temperature furnace body 1, and the stopper 24 is connected to the high-temperature furnace body 1. The position of the bottom of the rotating plate 23 corresponds to the position of the stopper 24, and the stopper 24 is placed between the rotating plate 23 and the exhaust hole 21.

[0025] First, the high-temperature furnace required for the preparation of refractory hollow balls is installed and adjusted, that is, the top cover 2 needs to be placed on the top of the high-temperature furnace body 1, the chassis 3 needs to be placed on the bottom of the high-temperature furnace body 1, the insulation tube 4 is sleeved in the high-temperature furnace body 1, the roller 5 is sleeved in the insulation tube 4, and the air pump 7 is installed at the outer end of the high-temperature furnace body 1, and one end of the air outlet pipe 19 on the air pump 7 is connected to the air pump 7, and the other end passes through the pipe hole 20 of the high-temperature furnace body 1 and the outer end of the insulation tube 4 cavity and is placed in the cavity. In this way, the installation of the high-temperature furnace is stably completed. Of course, the switch assembly 8 installed on the chassis 3 needs to be electrically connected to the external power supply, so that the air pump 7 and the motor 13 installed on the high-temperature furnace can be smoothly opened or closed under the control of the electrically connected switch assembly 8.

[0026] To prepare the refractory hollow balls, the chassis 3 needs to be placed on a plane. Since the chassis 3 is connected to the high-temperature furnace body 1, the high-temperature furnace body 1 is not only firmly connected and can be welded on the chassis 3, but also can be placed on a plane, so that the work of the high-temperature furnace body 1 can be carried out stably. The top cover 2 is provided with an annular groove 9, and the top of the high-temperature furnace body 1 matches the annular groove 9, that is, the top of the high-temperature furnace body 1 is inserted into the annular groove 9, and the top of the roller 5 is open and the bottom is closed, that is, when the top cover 2 is covered, the top of the roller 5 is sealed. For tightness and firmness, the top of the top cover 2 and the top of the high-temperature furnace body 1 can also be connected by screws and screw holes.

[0027] It is time to start working. The first step is to disassemble the top cover 2 from the top of the high-temperature furnace body 1 by controlling the screws and screw holes. Then the refractory hollow ball can be put in through the top of the high-temperature furnace body 1, naturally through the top of the open roller 5, so that the refractory hollow ball is smoothly placed in the roller 5, then it is necessary to control the top cover 2 to cover the top of the high-temperature furnace body 1, and do a good job of connection by means of screws and screw holes.

[0028] The second step is to control the switch assembly 8. Since the refractory hollow ball needs to be processed and prepared at high temperature, a high-temperature device is required in the drum 5. Generally, the heating device of the high-temperature furnace is a resistance wire, a silicon carbon rod and a silicon-molybdenum rod. Then, the current of the external power supply is passed into the resistance wire, the silicon carbon rod and the silicon-molybdenum rod, and the electrical energy is converted into heat energy, so that the drum 5 is placed in a high-temperature environment. In this way, the refractory hollow ball in the drum 5 is in a high-temperature environment, and the switch assembly 8 can still control the installation groove 12 of the chassis 3. The motor 13 is working, and the work of this motor 13 is to rotate the installed motor shaft 14, and the detachable connection between the bottom end of the closed drum 5 and the motor shaft 14 can be selected as a threaded connection, so the rotation of the motor shaft 14 can smoothly drive the drum 5 to rotate, that is, the refractory hollow balls in the drum 5 are driven to roll, which not only can balance the heating work of the refractory hollow balls, but also the rolling refractory hollow balls can reduce the probability of melting on the drum 5 due to heat, so that the spherical retention rate of the refractory hollow balls is higher.

[0029] The third step is that when the refractory hollow ball that needs to be heated at high temperature needs to be cooled, the air pump 7 can be turned on by the control of the switch assembly 8. A plurality of vents 22 are provided on the high-temperature furnace body 1. The vents 22 correspond to the exhaust holes 21 one by one, and the exhaust holes 21 correspond to the through holes 18 one by one. Then the gas generated by the operation of the air pump 7 is blown into the cavity through the outlet pipe 19, and then sprayed into the drum 5 through the exhaust holes 21 and the through holes 18 on the rolling shaft 6, that is, sprayed toward the refractory hollow ball rolling in the drum 5. Of course, some gas will remain in the exhaust holes 21 and the cavity. When cooling, whether the heating work of the resistance wire, silicon carbon rod and silicon molybdenum rod should be carried out depends on the actual situation, that is, the switch can be selected by the control of the switch assembly 8.

[0030] It is worth mentioning that a rotating plate 23 and a stopper 24 are installed at the vent hole 22, the top of the rotating plate 23 is placed at the top of the vent hole 22, and the stopper 24 is placed at the bottom of the vent hole 22. The top of the rotating plate 23 is detachably connected to the high-temperature furnace body 1, and the stopper 24 is connected to the high-temperature furnace body 1. The position of the bottom end of the rotating plate 23 corresponds to the position of the stopper 24. The stopper 24 is placed between the rotating plate 23 and the exhaust hole 21, that is, the distance between the stopper 24 and the bottom end of the rotating plate 23 is smaller than the distance between the top and bottom ends of the vent hole 22. In this way, when the high-temperature furnace is not working, the vent hole 22 is blocked by the rotating plate 23, and the outside gas cannot smoothly enter the vent hole 22, and the gas in the drum 5 cannot be automatically discharged through the vent hole 22. When the gas generated by the air pump 7 is filled, there is no external spray point in the drum 5, so there will be a state of gas surplus, and the surplus gas can rush to the vent 22 through the through hole 18 and the exhaust hole 21, and apply air pressure to the rotating plate 23 installed in the vent 22, so that the rotating plate 23 will rotate, thereby opening the vent 22, and the surplus gas will be discharged through the vent 22. The exhaust hole 21 here is both an inflation channel and an exhaust channel. In order to avoid that one of the inflation and exhaust work cannot be implemented, the air pump 7 can be selected in several ways, and it is not necessary to inflate each exhaust hole 21. The top of the rotating plate 23 can be optionally installed with a micro shaft, and the two ends of the micro shaft can be connected to the high-temperature furnace body 1 through micro rolling bearings, so that the rotation of the rotating plate 23 can be carried out smoothly.

[0031] Finally, the work of the air pump 7 and the motor 13 can be stopped, and after a period of time, the top of the drum 5 is opened to take out the refractory hollow balls prepared at high temperature in the drum 5.

[0032] In the preparation of the refractory hollow ball, the drum 5 is controlled to drive the refractory hollow ball inside the drum 5 to rotate, so as to achieve the purpose of installing a work component that allows the processing component to be manufactured at high temperature during rotation, and the top cover 2 is provided with a plurality of rotating grooves 10, which are distributed in a ring shape with the center of the top cover 2 as the base point, and a rolling bearing 11 is installed at the rotating groove 10, the outer ring 1 of the rolling bearing 11 is connected to the top cover 2, and the top end of the rolling shaft 6 is connected to the inner ring 1. The chassis 3 is provided with a plurality of rotating grooves 2 15, which are distributed in a ring shape with the center of the chassis 3 as the base point, and a rolling bearing 2 16 is installed at the rotating groove 2 15, the outer ring 2 of the rolling bearing 2 16 is connected to the chassis 3, and the bottom end of the rolling shaft 6 is connected to the inner ring 2. The insulation tube 4 is provided with a plurality of limit grooves 17, which are distributed in a ring shape with the center of the insulation tube 4 as the base point, and the exhaust hole 21 is placed at the limit groove 17.
