Description

Technical Field

[0001] The utility model belongs to the field of kilns, and specifically relates to a material pushing / pulling device, a kiln and a kiln heat insulation system thereof. Background Art

[0002] Kiln is a widely used ceramic sintering equipment, which can be used to produce daily-use porcelain, sanitary porcelain, bricks and tiles, electrode materials and other products. Taking the atmosphere protection roller kiln as an example, its basic working principle is: using a motor to drive multiple rows of rollers to rotate, the powder material in the graphite sagger is continuously sent into the closed furnace body of tens of meters, and after high-temperature sintering at about 850℃, it is taken out of the furnace and enters the next process.

[0003] The roller kiln body is generally divided into a preheating section, a constant temperature section and a cooling section. The constant temperature section is directly connected to the cooling section, which causes the heat of the constant temperature section to flow into the cooling section, resulting in energy waste. For this reason, a kiln insulation system is proposed. However, the configuration of the insulation system inevitably requires the design of a material pulling or pushing mechanism. However, since the direction of the material on the roller conveyor mechanism is always consistent, the currently designed material pulling or pushing mechanism requires at least two or more driving mechanisms, which leads to a relatively complex structure, increased failure rate and increased energy consumption.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] As attached Figure 1 -Attached Fig.10 As shown, the utility model provides a material pushing / pulling device 1, comprising a linear driving mechanism 11 and a pulling block 12, wherein the pulling block 12 is hingedly arranged at the output end of the linear driving mechanism 11, the linear driving mechanism 11 is used to drive the pulling block 12 to move linearly, and the pulling block 12 can rotate at the output end of the linear driving mechanism 11, and the rotation angle of the pulling block 12 relative to the push / pull output stroke direction of the linear driving mechanism 11 is between 0° and 90°, refer to the attached Figure 6 and attached Figure 7 , that is, when the material push / pull device 1 is used as a material pulling device, the rotation angle of the material pulling block 12 is between 0° and 90° relative to the material pulling output stroke direction of the linear drive mechanism 11 (the reset stroke direction of the linear drive mechanism 11); refer to the attached Figure 8 When the material push / pull device 1 is used as a material pushing device, the rotation angle of the material pulling block 12 is between 0° and 90° relative to the material pushing output stroke direction of the linear drive mechanism 11 (the extension stroke direction of the linear drive mechanism 11);

[0035] Preferably, a rotation limiting structure is provided on the hinge structure between the pulling block 12 and the output end of the linear drive mechanism 11 for limiting the pulling block 12 from further rotating in a direction greater than 90°. When at 90°, the pulling block 12 is perpendicular to the output end of the linear drive mechanism 11. Restricted by the rotation limiting structure, the pulling block 12 cannot rotate to an angle greater than 90°. When the material pushing / pulling device 1 is used as a pulling device, when the pulling block 12 is at 0°, the pulling block 12 is tightly attached to the output end of the linear drive mechanism 11, and the pulling block 12 will not rotate to an angle less than 0°. When the material pushing / pulling device 1 is used as a pushing device, the material will push the pulling block 12 to rotate to a minimum of 0° and will not rotate to an angle less than 0°.

[0036] When the material pushing / pulling device 1 is performing material pulling work, the material pulling output stroke direction of the linear drive mechanism 11 is the same as the moving direction of the material. The linear drive mechanism 11 is arranged at the downstream end, and the material pulling block 12 is arranged at the upstream end. The linear drive mechanism 11 drives the material pulling block 12 to move to the downstream end of the material. Before the material pulling block 12 contacts the material, the material pulling block 12 is in a 90° state, and during the extension process of the linear drive mechanism 11, the material pulling block 12 will contact the upstream end of the material. At this time, the material pulling block 12 will rotate due to touching the material, and the material pulling block 12 will continue to move in line with the side wall of the material until the material pulling block 12 passes the downstream end of the material. At this time, the elastic member 13 will drive the material pulling block 12 to be in a 90° state, and then the linear drive mechanism 11 is reset, the material pulling block 12 will abut the downstream end of the material and be restricted by the rotation limit structure and cannot rotate. During the resetting process of the linear drive mechanism 11, the material is pulled to move, thereby completing the material pulling work.

[0037] When the material push / pull device 1 is in the material pushing operation, the pushing output stroke direction of the linear drive mechanism 11 is the same as the moving direction of the material. Figure 8 At this time, the linear drive mechanism 11 is set at the upstream end, and the pulling block 12 is set at the downstream end. The material is transported through the material conveying device 4, and the material pushing / pulling device 1 remains stationary. During the movement of the material, the upstream end of the material will contact the pulling block 12. At this time, the pulling block 12 will rotate in the 0° direction due to contacting the material, and the pulling block 12 will continue to move in line with the side wall of the material until the pulling block 12 passes the downstream end of the material and leaves the material. At this time, the elastic member 13 will drive the pulling block 12 to be in a 90° state, and then the linear drive mechanism 11 will extend, and the pulling block 12 will abut the downstream end of the material and be restricted by the rotation limit structure and cannot rotate. In the process of the linear drive mechanism 11 extending, the material is pushed to move, thereby completing the material pushing work.

[0038] It should be noted that the material push / pull device 1 needs to work in coordination with the material conveying direction, that is, the material conveying direction is consistent with the telescopic direction of the linear drive mechanism 11, and the material pulling block 12 will be within the moving range of the material.

[0039] The material pulling device provided by the utility model only needs a linear drive mechanism 11 to complete the pushing / pulling work of the material, and no interlocking structure is required on the material. The material pushing / pulling adaptability is strong, and the entire material pushing / pulling device 1 has a simple overall structure, is convenient and fast to operate, and has low energy consumption. At the same time, it is also suitable for pushing or pulling materials and is suitable for different working conditions.

[0040] In one of the embodiments, a bevel 121 is provided on the side of the pulling block 12 away from the push / pull output stroke direction of the linear drive mechanism and away from the hinge. In this embodiment, when the pulling block 12 touches the upstream of the material, the bevel 121 first contacts the material. At this time, in the relative movement between the pulling block 12 and the material, the material will move along the bevel 121, thereby driving the pulling block 12 to rotate, thereby improving the smoothness of the rotation of the pulling block 12.

[0041] In one embodiment, the material push / pull device 1 further includes an isolation cover 14 isolated from the furnace body 2, the body of the linear drive mechanism 11 is arranged on the isolation cover 14, a sliding hole 141 is arranged on the isolation cover 14, and the output end of the linear drive mechanism 11 passes through the sliding hole 141 to hinge the material pulling block 12. In this embodiment, the isolation cover 14 can isolate the dust and temperature in the furnace body 2. When the furnace body 2 is in a high temperature environment, the high temperature can be prevented from acting on the linear drive mechanism 11, reducing the performance requirements of the linear drive mechanism 11 and increasing the service life of the linear drive mechanism 11. Preferably, the isolation cover 14 is arranged on the inner side wall of the furnace body 2, so that its output end can directly act on the inside of the furnace body 2.

[0042] In one embodiment, the linear drive mechanism 11 includes a linear module 111 and a pull rod 112 arranged on the output end of the linear module 111. The pull rod 112 passes through the sliding hole 141 to hinge the pulling block 12. In this embodiment, the pull rod 112 is used as the output end of the linear drive mechanism 11, so that the output end of the linear drive mechanism 11 can be conveniently extended out of the isolation cover 14. The linear module 111 has the advantages of high control accuracy and strong load capacity, and can drive heavy materials to move with high precision.

[0043] In one of the embodiments, a guide sleeve 142 is provided inside the isolation cover 14 on the outside of the sliding hole 141, and the pull rod 112 is slidably provided inside the guide sleeve 142. By providing the guide sleeve 142, on the one hand, the contact area between the isolation cover 14 and the pull rod 112 can be increased, thereby improving the sliding effect; on the other hand, the connection path between the isolation cover 14 and the furnace body 2 can be increased, thereby reducing the possibility of dust and high temperature entering the isolation cover 14 from the sliding hole 141. Preferably, a sealing ring 143 is also provided between the guide sleeve 142 and the pull rod 112. At this time, the pull rod 112 is slidably sealed on the isolation cover 14, thereby further improving the isolation effect.

[0044] In one embodiment, the elastic member 13 is a torsion spring, one torsion arm of the torsion spring abuts against the output end of the linear drive mechanism 11, and the other torsion arm abuts against the pulling block 12. Using a torsion spring as the elastic member 13 has the advantages of simple structure and easy installation.

[0045] The utility model also provides a kiln, comprising a furnace body 2 and the material pushing / pulling device 1 mentioned above.

[0046] The utility model also provides a kiln heat insulation system, comprising a temperature-insulating furnace door 3, a material conveying device 4 and the kiln;

[0047] The insulation furnace door 3 is arranged in the furnace body 2. When the insulation furnace door 3 is closed, the furnace body 2 is divided into two independent first furnace chambers 21 and second furnace chambers 22. When the second insulation furnace door 3 is opened, the first furnace chamber 21 and the second furnace chamber 22 are connected. Preferably, the insulation furnace door 3 is an upper and lower opening furnace door, that is, the furnace door enters or leaves the furnace body 2 vertically from the upper end of the furnace body 2, so that the conveying space in the furnace body 2 can be not affected during the opening and closing process;

[0048] The material conveying device 4 is disposed in the furnace body 2 and communicates with the first furnace cavity 21 and the second furnace cavity 22. The material conveying device 4 is used to carry and convey materials, and the materials can be conveyed from the second furnace cavity 22 to the first furnace cavity 21 through the material conveying device 4.

[0049] The material pushing / pulling device 1 is arranged in the second furnace chamber 22, and is used to pull the material in the first furnace chamber 21 into the second furnace chamber 22 when the insulation furnace door 3 is opened; at this time, the material pushing / pulling device 1 is used as a material pulling device, and can pull the material from the second furnace chamber 22 into the first furnace chamber 21 at a conveying speed faster than the material conveying device 4, thereby improving the material transfer efficiency. When the atmosphere or temperature conditions in the first furnace chamber 21 and the second furnace chamber 22 are inconsistent, the opening time of the insulation furnace door 3 can be shortened, thereby reducing the mutual interference between the two furnace chambers.

[0050] Alternatively, the material pushing / pulling device 1 is arranged in the first furnace chamber 21, and is used to push the material in the first furnace chamber 21 into the second furnace chamber 2 when the insulation furnace door 3 is opened; at this time, the material pushing / pulling device 1 is used as a material pushing device, and can push the material from the second furnace chamber 22 into the first furnace chamber 21 at a conveying speed faster than the material conveying device 4, thereby improving the material transfer efficiency. When the atmosphere or temperature conditions in the first furnace chamber 21 and the second furnace chamber 22 are inconsistent, the opening time of the insulation furnace door 3 can be shortened, thereby reducing the mutual interference between the two furnace chambers.

[0051] This heat insulation system is particularly suitable for application scenarios where the temperatures of the first furnace chamber 21 and the second furnace chamber 22 are inconsistent. For example, the first furnace chamber 21 is a cooling section, and the second furnace chamber 22 is a heating section. The material is transported from the heating section to the cooling section. If the insulation furnace door 3 is not provided, the first furnace chamber 21 and the second furnace chamber 22 are connected, and the different temperature environments of the two will affect each other, thereby increasing energy consumption. If the material push / pull device 1 is not provided, the material sintering and cooling process takes a long time, and the conveying speed of the material conveying device 4 is generally very slow. Therefore, it takes a long time for the material to be transferred from the second furnace chamber 22 to the first furnace chamber 21 through the material conveying device 4, and there will also be a problem of large mutual interference between the first furnace chamber 21 and the second furnace chamber 22. By providing the insulation furnace door 3 and the material push / pull device 1, the efficiency of the material entering the heating section from the cooling section can be greatly improved without affecting the sintering and cooling of other materials, thereby reducing energy consumption. It should be noted that the furnace body 2 can be one furnace body, in which case the first furnace cavity 21 and the second furnace cavity 22 are both internal cavities of the furnace body; the furnace body 2 can also be two interconnected furnace bodies, in which case the first furnace cavity 21 and the second furnace cavity 22 are respectively internal cavities of two furnace bodies.

[0052] In one of the embodiments, a group of material pushing / pulling devices 1 are provided at each end in the width direction of the furnace body 2, and the two groups of material pushing / pulling devices 1 operate synchronously. In this embodiment, the two groups of material pushing / pulling devices 1 respectively pull the two sides of the downstream end of the material or push the two sides of the downstream end of the material to improve the stability and carrying capacity of the pushed / pulled material.

[0053] In one embodiment, the material conveying device 4 is a roller conveying device. Preferably, the rollers of the roller conveying device in the heating section have high temperature resistance, while the rollers of the roller conveying device in the cooling section are water-cooled rollers, which can cool the material and improve the cooling effect of the cooling section.

[0054] The above is only an embodiment and does not limit the present invention in any way. Any person skilled in the art can make many possible changes, modifications or modifications to the present invention without departing from the scope of the present invention by using the above disclosed technical contents. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the present invention should fall within the scope of protection of the present invention.
