Technical Field

[0001] The utility model relates to the technical field of hollow ball bricks, in particular to a blank making device for alumina hollow ball bricks. Background Art

[0002] Hollow ball bricks are lightweight refractory materials made from hollow refractory balls. Hollow ball bricks have low apparent porosity, low thermal conductivity, good thermal shock resistance, and high high-temperature structural strength. They can be directly laid in the lining of high-temperature kilns in contact with flames, and can also be used to manufacture high-temperature furnace tubes, trays, protective covers, etc.

[0003] When making hollow ball bricks, mud raw materials are usually injected into the corresponding mold for molding. However, during the injection process, the mud cannot be evenly distributed in the mold, resulting in more mud in some areas and less mud in some areas, which will affect the subsequent blank forming effect.

[0015] 1. The utility model is provided with a knocking mechanism, which can start the motor while the slurry is injected from the injection pipe. The motor will drive the driving rod and the extrusion block to rotate. When the raised part of the extrusion block is squeezed to the inner wall of the extrusion ring, the extrusion ring and the movable plate will move downward and compress the spring at the same time. When the raised part of the extrusion block is not in contact with the inner wall of the extrusion ring, it is affected by the reaction force of the spring and drives the movable plate and the knocking rod to move upward.

The second push rod will drive the second piston to move downward, compressing the body in the compression cylinder into the transmission pipe and then entering the air collecting cylinder. Under the influence of air pressure, the first piston and the first push rod will move upward, and at the same time drive the support block to move upward to compress the spring. When the extrusion ring moves upward, it drives the second push rod and the second piston to move upward. At this time, the compression cylinder is under negative pressure, and gas will enter through the air intake pipe. In this way, the spring is squeezed by the intermittent upward movement of the support block, and the elastic coefficient of the spring is gradually increased, thereby increasing the knocking force of the knocking mechanism, so that the mud can be evenly distributed when sufficient vibration force is generated, further improving the blank forming effect.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 - Figure 5 , the utility model provides a technical solution:

[0025] Example 1:

[0026] A device for making a hollow alumina ball brick comprises a base 1, a fixed mold 2, a movable mold 3 and an injection pipe 4, the fixed mold 2 is fixedly mounted on the top of the base 1, the movable mold 3 is located on the top of the fixed mold 2, the injection pipe 4 is fixedly connected to the top of the movable mold 3, a placement groove 5 is provided inside the base 1, a movable plate 6 is provided inside the placement groove 5, a knocking rod 7 is fixedly connected to the top of the movable plate 6, a gas collecting cylinder 8 is fixedly connected to the inner wall of the placement groove 5, a first piston 9 is provided inside the gas collecting cylinder 8, a first push rod 10 is fixedly connected to the top of the first piston 9, the top of the first push rod 10 passes through the top of the gas collecting cylinder 8 and is fixedly connected to a support block 11, a spring 12 is fixedly connected to the top of the support block 11, the top of the spring 12 is fixedly connected to the bottom of the movable plate 6, a knocking mechanism is provided on one side of the base 1, and a gas collecting mechanism is provided at the bottom of the knocking mechanism;

[0027] The knocking mechanism includes a motor 13 fixedly mounted on one side of the base 1, the output end of the motor 13 is fixedly connected to a driving rod 14, one end of the driving rod 14 passes through the interior of the placement groove 5 and is fixedly connected to an extrusion block 15, and the bottom of the movable plate 6 is fixedly connected to an extrusion ring 16, and the extrusion block 15 is located inside the extrusion ring 16.

[0028] In this embodiment, it is considered that when making hollow spherical bricks, the slurry raw materials are usually injected into the corresponding mold for molding. However, during the injection process, the slurry cannot be evenly distributed in the mold, resulting in more slurry in some areas and less slurry in some areas, which will affect the subsequent molding effect. Therefore, by setting a knocking mechanism, the motor 13 can be started while the slurry is injected from the injection pipe 4. The motor 13 drives the driving rod 14 and the extrusion block 15 to rotate. When the convex part of the extrusion block 15 is squeezed to the inner wall of the extrusion ring 16, as shown in FIG. Figure 5 As shown, the extrusion ring 16 and the movable plate 6 will move downward, compressing the spring 12 at the same time. When the raised portion of the extrusion block 15 is not in contact with the inner wall of the extrusion ring 16, the movable plate 6 and the knocking rod 7 are driven upward by the reaction force of the spring 12. In this cycle, the knocking rod 7 intermittently knocks on the bottom of the fixed mold 2, generating vibration, so that the slurry inside the fixed mold 2 can be evenly distributed, thereby improving the effect of subsequent blank forming;

[0029] The invention solves the problem that when making hollow ball bricks, mud raw materials are usually injected into the corresponding mold for molding. However, during the injection process, the mud cannot be evenly distributed in the mold, resulting in more mud in some areas and less mud in some areas, which will affect the subsequent blank molding effect.

[0030] Sliding blocks 27 are fixedly connected to both sides of the movable plate 6 , and a sliding groove 28 for use with the sliding blocks 27 is formed on the inner wall of the placement groove 5 .

[0031] In this embodiment, by providing a sliding block 27 and a sliding groove 28, when the raised end of the extrusion block 15 squeezes the inner wall of the extrusion ring 16, the movable plate 6 and other structures are restricted to move downward along the track of the sliding block 27 and the sliding groove 28, while improving its stability during movement.

[0032] The top of the knock rod 7 is spherical and contacts the bottom of the fixed mold 2 .

[0033] In this embodiment, the top of the knocking rod 7 is set to be spherical, which can prevent the knocking rod 7 from causing damage to the bottom of the fixed mold 2 when knocking. At the same time, the spherical design can increase the vibration force generated during knocking.

[0034] Example 2:

[0035] On the basis of Example 1, the knocking mechanism in this embodiment can generate vibration force by knocking, so that the mud can be evenly distributed in the fixed mold 2. However, considering that as the mud continues to be injected, the vibration force generated by the knocking mechanism is difficult to meet the demand for uniform distribution of the mud, the air collecting mechanism in this application includes a second push rod 17 fixedly connected to the bottom of the extrusion ring 16, and the inner wall of the mounting groove 5 is fixedly connected to the compression cylinder 18. The bottom of the second push rod 17 passes through the interior of the compression cylinder 18 and is fixedly connected to the second piston 19. One side of the compression cylinder 18 is fixedly connected to the air intake pipe 20, and the other side of the compression cylinder 18 is fixedly connected to the transmission pipe 21. One end of the transmission pipe 21 is fixedly connected to one side of the air collecting cylinder 8.

[0036] In this embodiment, it is considered that as the mud is continuously injected, the vibration force generated by the knocking mechanism is difficult to meet the demand for uniform distribution of the mud. Therefore, by setting an air collecting mechanism, when the extrusion ring 16 moves downward, it drives the second push rod 17 to move downward, and the second push rod 17 will drive the second piston 19 to move downward, compressing the body in the compression cylinder 18 into the transmission pipe 21, and then enters the air collecting cylinder 8. Under the influence of air pressure, the first piston 9 and the first push rod 10 will move upward, and at the same time drive the support block 11 to move upward, compressing the spring 12. When the extrusion ring 16 moves upward, it drives the second push rod 17 and the second piston 19 to move upward. At this time, the compression cylinder 18 is under negative pressure, and gas will enter through the air inlet pipe 20. In this cycle, the support block 11 intermittently moves upward to squeeze the spring 12, gradually increasing the elastic coefficient of the spring 12, and then increasing the knocking force of the knocking mechanism, so that it can generate enough vibration force to make the mud evenly distributed, further improving the effect of blank forming;

[0037] The problem that as the mud is continuously injected, the vibration force generated by the knocking mechanism is difficult to meet the requirement of evenly distributing the mud is solved.

[0038] A solenoid valve 22 is fixedly mounted on one end of the gas collecting cylinder 8 , and a controller 23 is fixedly mounted on one side of the base 1 . The controller 23 is signal-connected to the solenoid valve 22 .

[0039] In this embodiment, by providing the solenoid valve 22 and the controller 23 , the solenoid valve 22 can be activated by the built-in PLC module of the controller 23 to discharge the gas in the gas cylinder 8 so that the knocking mechanism can restore the initial vibration force.

[0040] A pressure sensor 24 is provided inside the gas collecting cylinder 8 , and the pressure sensor 24 is connected to the controller 23 for signal communication.

[0041] In this embodiment, by setting a pressure sensor 24, when the first piston 9 moves to the limit, the pressure sensor 24 will receive a signal that the air pressure in the air collecting cylinder 8 is too high, and transmit it to the controller 23. The built-in PLC module of the controller 23 will also start the solenoid valve 22 to open, which will avoid the phenomenon of jamming between the structures.

[0042] A first one-way valve 25 is fixedly mounted on the surface of the air intake pipe 20 , and a second one-way valve 26 is fixedly mounted on one end of the transmission pipe 21 .

[0043] In this embodiment, a first one-way valve 25 and a second one-way valve 26 are provided. The first one-way valve 25 is a valve that can only intake air into the compression cylinder 18, and the second one-way valve 26 is a valve that can only intake air into the gas collecting cylinder 8. Therefore, when the gas in the compression cylinder 18 is under pressure, the gas will enter the gas collecting cylinder 8 through the transmission pipe 21. When the compression cylinder 18 is under negative pressure, the gas will enter the compression cylinder 18 through the air intake pipe 20.

[0044] Working principle: When the slurry is injected from the injection pipe 4, the motor 13 is started, and the motor 13 drives the driving rod 14 and the extrusion block 15 to rotate. When the convex part of the extrusion block 15 is squeezed to the inner wall of the extrusion ring 16, Figure 5 As shown, the extrusion ring 16 and the movable plate 6 will move downward, compressing the spring 12 at the same time. When the raised portion of the extrusion block 15 is not in contact with the inner wall of the extrusion ring 16, the movable plate 6 and the knocking rod 7 are driven upward by the reaction force of the spring 12. In this cycle, the knocking rod 7 intermittently knocks on the bottom of the fixed mold 2, generating vibration, so that the slurry inside the fixed mold 2 can be evenly distributed, thereby improving the effect of subsequent blank forming;

[0045] When the extrusion ring 16 moves downward, it drives the second push rod 17 downward, and the second push rod 17 drives the second piston 19 downward, compressing the body in the compression cylinder 18 into the transmission pipe 21, and then into the gas collecting cylinder 8. Affected by the air pressure, the first piston 9 and the first push rod 10 will move upward, and at the same time drive the support block 11 to move upward to compress the spring 12. When the extrusion ring 16 moves upward, it drives the second push rod 17 and the second piston 19 to move upward. At this time, there is negative pressure in the compression cylinder 18, and gas will enter through the air intake pipe 20. In this way, the support block 11 moves upward intermittently to squeeze the spring 12, gradually increasing the elastic coefficient of the spring 12, and then increasing the force of the knocking mechanism, so that it can generate enough vibration force to evenly distribute the mud, further improving the effect of blank forming.

[0046] It should be noted that the motor 13, solenoid valve 22, controller 23 and pressure sensor 24 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the motor 13, solenoid valve 22, controller 23 and pressure sensor 24 are clear to those skilled in the art, so they will not be described in detail.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
