Description

Technical Field

[0001] The utility model relates to the technical field of kiln structures, in particular to an adjustable kiln door inlet structure. Background Art

[0002] The kiln is mainly used to sinter ceramic or tile blanks. The kiln consists of a kiln body, combustion equipment (device), ventilation equipment, conveying equipment and a control system. The blanks enter from one end in sequence, are preheated, fired, and cooled, and then exit from the other end to be fired into products. The kiln door is the main component of the kiln structure, and the inlet size of the kiln door at the kiln head of the existing kiln exhaust is basically fixed. When the kiln produces ceramic tiles with large thickness and small width, because the kiln inlet size is fixed, when the product passes through the kiln door inlet, the kiln door inlet will cause the product to enter due to the small width. There are large gaps on the left and right sides of the inlet. This is because the flue gas temperature inside the kiln body will be higher than the external gas temperature, resulting in a large negative pressure at the inlet of the kiln door. The larger the gaps on the left and right sides of the inlet, the more external cold air will be sucked into the kiln body by the inlet, which will reduce the exhaust flue gas temperature inside the kiln, thereby reducing the stability of the inside of the kiln. Therefore, it is necessary to increase the combustion temperature of the burner inside the kiln to ensure the normal operation of the kiln, so as to ensure the normal operation of the kiln. At that time, adopting this method would increase energy consumption during product production and increase production costs. Utility Model Content

[0003] In order to overcome the defects of the prior art, the utility model provides an adjustable kiln door inlet structure.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an adjustable kiln door inlet structure, comprising a kiln body, a cavity is opened inside the kiln body, a kiln door is arranged at the inlet end of the cavity, a feed port is opened at the center of the kiln door, the feed port is connected to the cavity, a conveying roller group is arranged inside the kiln body, one end of the conveying roller group extends outward through the feed port, a first blocking module and a second blocking module are arranged on both sides of the feed port, and the adjustment ends of the first blocking module and the second blocking module are both facing the feed port.

[0005] Further description of this solution: the first blocking module and the second blocking module have the same structure, and the first blocking module and the second blocking module are mirror-imaged with the center line of the feed port as the axis of symmetry.

[0006] Specifically, the first blocking module includes a locking stud, a first baffle and a butterfly nut. The locking stud is arranged on one side of the feed port. The first baffle is movably installed on one side of the locking stud. A strip hole is opened inside the first baffle. One end of the locking stud passes through the first baffle through the strip hole. The end of the locking stud that passes through the first baffle is threadedly connected with a butterfly nut.

[0007] More specifically, the diameter of the locking stud is smaller than the diameter of the strip hole, and the width of the first baffle is greater than the height of the feed port.

[0008] Further description of this solution: a flip cover module is provided inside the feed port, and the flip cover module includes a hinge and a second baffle. The fixed end of the hinge is provided at the upper part of the feed port and is fixedly connected to the kiln door. The movable end of the hinge faces the feed port and is provided with a second baffle.

[0009] Further description of this solution: the bottom surface of the second baffle is lower than the bottom surface of the strip-shaped hole.

[0010] The beneficial effect of the present invention is that when the kiln needs to produce ceramic tile products with large thickness and small width, the first blocking module and the second blocking module on both sides of the feed port can be adjusted. By adjusting the positions of the first blocking module and the second blocking module, the gaps on the left and right sides of the feed port can be reduced when the kiln is producing ceramic tile products with large thickness and small width, thereby reducing the amount of external cold air sucked into the kiln body by the feed port, thereby increasing the temperature of the kiln exhaust gas and the temperature of the drying air, thereby ensuring the temperature inside the kiln is stable, without increasing the combustion temperature of the burner inside the kiln, and ensuring the normal operation of the kiln, further reducing energy consumption during product production and reducing production costs.

[0019] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0020] As attached Figure 1 、 2 As shown in Figures 3, 4, 5, 6 and 7, the utility model provides an adjustable kiln door inlet structure, including a kiln body 1, a cavity 2 is opened inside the kiln body 1, a kiln door 3 is arranged at the inlet end of the cavity 2, a feed port 5 is opened at the center of the kiln door 3, the feed port 5 is communicated with the cavity 2, a conveying roller group 4 is provided inside the kiln body 1, one end of the conveying roller group 4 extends outward through the feed port 5, and a first blocking module 6 and a second blocking module 7 are provided on both sides of the feed port 5, and the adjustment ends of the first blocking module 6 and the second blocking module 7 are both facing the feed port 5.

[0021] When the kiln needs to process ceramic tile products with large thickness and small width: first, place the products on the upper surface of the conveyor roller group 4, and connect the conveyor roller group 4 to the external driving member to drive the conveyor roller group 4 to rotate. When the conveyor roller group 4 rotates, it can drive the products placed on the upper surface of the conveyor roller group 4 to move, so that the products can be moved to the feed port 5;

[0022] Subsequently, when the product moves to the feed port 5, the first blocking module 6 and the second blocking module 7 on both sides of the feed port 5 can be adjusted. By adjusting the positions of the first blocking module 6 and the second blocking module 7, the first blocking module 6 and the second blocking module 7 can be made closer to the product, thereby reducing the gaps on the left and right sides of the feed port 5 when the kiln is producing ceramic tile products with large thickness and small width, thereby reducing the amount of external cold air sucked into the kiln body 1 by the feed port 5, thereby increasing the exhaust gas temperature and the drying air temperature of the kiln, thereby ensuring the temperature inside the kiln stable, without increasing the combustion temperature of the burner inside the kiln, and ensuring the normal operation of the kiln, further reducing energy consumption during product production and reducing production costs.

[0023] It should be noted that the first blocking module 6 and the second blocking module 7 are mirror-imaged with the center line of the feed port 5 as the axis of symmetry.

[0024] As attached Figure 1 、 2 As shown in Figures 3, 4, 5, 6 and 7, the first blocking module 6 includes a locking stud 61, a first baffle 62 and a butterfly nut 63. The locking stud 61 is arranged on one side of the feed port 5. The first baffle 62 is movably installed on one side of the locking stud 61. A bar hole 621 is provided inside the first baffle 62. One end of the locking stud 61 passes through the first baffle 62 through the bar hole 621, so that the first baffle 62 can move left and right through the cooperation of the locking stud 61 and the bar hole 621. One end of the locking stud 61 that passes through the first baffle 62 is threadedly connected with a butterfly nut 63.

[0025] When the position of the first baffle 62 needs to be adjusted: first rotate the butterfly nut 63 counterclockwise to enable the butterfly nut 63 to fit through the thread of the locking stud 61, thereby releasing the pressure on the first baffle 62. After the release is completed, the first baffle 62 is manually moved. The first baffle 62 can move toward the product through the cooperation between the locking stud 61 and the strip hole 621, so that the first baffle 62 can be closer to the product, thereby reducing the gap between the feed port 5 and the product and reducing the amount of external cold air sucked into the kiln body 1 by the feed port 5.

[0026] When the first baffle 62 is adjusted, the butterfly nut 63 is rotated clockwise so that the butterfly nut 63 can press the first baffle 62 by cooperating with the thread of the locking stud 61, thereby fixing the first baffle 62.

[0027] It should be noted that the diameter of the locking stud 61 is smaller than the diameter of the strip hole 621, so as to ensure that the locking stud 61 can move in the strip hole 621, and the width of the first baffle 62 is greater than the height of the feed port 5, so as to ensure that the first baffle 62 can block the feed port 5.

[0028] It should be noted that the first blocking module 6 and the second blocking module 7 have the same structure, and thus the working principles of the second blocking module 7 and the first blocking module 6 are consistent, and thus detailed description is omitted.

[0029] As attached Figure 1 、 2 , 3, 4, 5, 6 and 7, a flip cover module 8 is subsequently provided inside the feed port 5, and the flip cover module 8 includes a hinge 81 and a second baffle 82. The fixed end of the hinge 81 is provided at the upper part of the feed port 5 and is fixedly connected to the kiln door 3. The movable end of the hinge 81 faces the feed port 5 and is provided with a second baffle 82.

[0030] When it is necessary to clean the upper surface of the conveying roller group 4 in the cavity 2: first move the first blocking module 6 and the second blocking module 7 to a position away from the feed port 5 to avoid obstruction when the flip module 8 is working, and then lift the second baffle 82 upward so that the second baffle 82 can be flipped by cooperating with the hinge 81, so as to further open the feed port 5. By opening the feed port 5, it is convenient for the cleaning tool to reach into the upper surface of the conveying roller group 4 in the cavity 2, so as to facilitate the cleaning of the upper surface of the conveying roller group 4 in the cavity 2.

[0031] The bottom surface of the second baffle 82 is lower than the bottom surface of the strip hole 621 , so that the second baffle 82 can block the strip hole 621 from communicating with the cavity 2 , thereby preventing external air from entering the cavity 2 through the strip hole 621 .

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
