Description

Technical Field

[0001] The utility model relates to the technical field of shuttle kilns, in particular to a sealing mechanism for shuttle kilns. Background Art

[0002] A shuttle kiln is an intermittent firing kiln. Its structure is similar to the firing zone of a tunnel kiln, consisting primarily of a kiln chamber and a kiln cart. The blanks are stacked on the kiln cart's scaffolding and pushed into the kiln chamber for firing. After firing and cooling, the kiln cart and the finished product are pulled out of the kiln chamber.

[0003] During the firing process of the shuttle kiln, the kiln door needs to be closed to prevent the internal heat from overflowing and affecting the temperature in the sintering chamber;

[0004] The kiln doors of existing shuttle kilns may deform, carbonize, or burn through under high-temperature conditions, resulting in a decrease in sealing performance. Furthermore, improperly designed sealing of the kiln door, such as poor fit between the door and frame, or aging or damage to the sealing strip, will affect the sealing performance of the kiln door. Poor sealing can lead to a large amount of heat loss in the kiln, increasing energy consumption and reducing thermal efficiency. Furthermore, poor sealing of the kiln door can cause temperature fluctuations in the kiln, affecting the firing quality of the finished product. Therefore, a sealing mechanism for a shuttle kiln is proposed to address the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides a sealing mechanism for a shuttle kiln, which has the advantages of good sealing performance and solves the problem that the traditional shuttle kiln door is prone to heat overflow from the kiln due to loose sealing during use.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a sealing mechanism for a shuttle kiln, comprising a kiln, wherein a mounting seat is provided at the mouth of the kiln, a connecting port is fixedly connected to the mounting seat, a connecting plate is further provided on the mounting seat, a sealing assembly is rotatably connected to the connecting plate for sealing, and two locking assemblies are further provided on the mounting seat for fixing the sealing assembly;

[0007] The sealing assembly includes a sealing door for sealing the kiln, a connecting platform is fixedly connected to the top of the sealing door, and the connecting platform is rotatably connected to the connecting plate. A sealing plate for support is also provided in the sealing door, and a thermal expansion tube for sealing the connecting port is provided between the sealing door and the sealing plate. A pressure relief valve for relieving pressure on the thermal expansion tube is provided on the sealing door, and the pressure relief valve remains in communication with the connecting plate.

[0008] Furthermore, the two locking assemblies include a support seat, a connecting shaft is fixedly connected inside the support seat, the connecting shaft is rotatably connected to a connecting rod, and the other end of the connecting rod is fixedly connected to a mounting rod.

[0009] Furthermore, a threaded platform is fixedly connected to the mounting rod, and a threaded rod is internally threadedly connected to the threaded platform.

[0010] Furthermore, one end of the threaded rod is fixedly connected to a pressing platform for limiting the sealing door.

[0011] Furthermore, the other end of the threaded rod is fixedly connected to an adjustment handle for easy adjustment by staff.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] 1. The sealing mechanism for the shuttle kiln is equipped with a thermal expansion tube so that it can effectively seal the sealing plate during use, thereby preventing the sealing door and the sealing plate from deforming after long-term use, which may lead to a loose fit with the connecting plate. This increases its stability during use and avoids heat overflow due to loose sealing, which may cause energy waste and affect the quality of fired products.

[0014] Second, the sealing mechanism for the shuttle kiln is provided with a threaded rod and a pressing table, which enables it to effectively control the sealing door and the connecting plate to form a tight fit during use, effectively avoiding the situation in which a large amount of heat is lost in the kiln due to heat overflow during use, thereby increasing energy consumption and reducing thermal efficiency.

[0020] 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.

[0021] Example 1:

[0022] See also Figure 1-3 In this embodiment, a sealing mechanism for a shuttle kiln includes a kiln 1, which is characterized in that: a mounting seat 11 is provided at the mouth of the kiln 1, a connecting port 12 is fixedly connected to the mounting seat 11, a connecting plate 13 is further provided on the mounting seat 11, a sealing assembly 2 for sealing is rotatably connected to the connecting plate 13, and two locking assemblies 3 for fixing the sealing assembly 2 are further provided on the mounting seat 11; the sealing assembly 2 includes a sealing door 21 for sealing the kiln 1, a connecting platform 24 is fixedly connected to the top of the sealing door 21, the connecting platform 24 is rotatably connected to the connecting plate 13, a sealing plate 22 for support is further provided in the sealing door 21, a thermal expansion tube 23 for sealing the connecting port 12 is provided between the sealing door 21 and the sealing plate 22, a pressure relief valve 25 for relieving pressure on the thermal expansion tube 23 is provided on the sealing door 21, and the pressure relief valve 25 is kept in communication with the connecting plate 13.

[0023] As a preferred technical solution in this embodiment: during actual use, when the kiln 1 is working, the staff can close the sealing door 21 to form a sealing effect on the kiln 1. During the closing of the sealing door 21, the connecting plate 13 is just located between the thermal expansion tube 23 and the sealing plate 22. The staff can then heat up the kiln 1. After the kiln 1 is heated, the heat will be transferred to the sealing door 21 and the thermal expansion tube 23. When the thermal expansion tube 23 is heated, it will expand. After the thermal expansion tube 23 expands, it will achieve a tight fit effect on the four sides of the connecting plate 13, thereby effectively reducing heat overflow. When the sintering is completed, the staff needs to open the sealing door 21. The pressure relief valve 25 can be controlled to discharge the hot air inside the thermal expansion tube 23. At this time, the thermal expansion tube 23 returns to its normal size. At this time, the staff can easily open the sealing door 21, avoiding the difficulty in opening and closing the sealing door 21 due to the expansion of the thermal expansion tube 23.

[0024] The technical effects brought about by the above embodiment are: by providing a thermal expansion tube 23, the sealing plate 22 can be effectively sealed during use, thereby avoiding deformation of the sealing door 21 and the sealing plate 22 after long-term use, resulting in a loose fit between the connecting plate 13, increasing its stability during use, and avoiding heat overflow due to loose sealing, resulting in energy waste and affecting the quality of fired products.

[0025] Example 2:

[0026] See also Figure 4 To further enhance the sealing effect of the sealing door 21, the two locking assemblies 3 in this embodiment include a support base 31. A connecting shaft 32 is fixedly connected to the support base 31. A connecting rod 33 is rotatably connected to the connecting shaft 32. The other end of the connecting rod 33 is fixedly connected to a mounting rod 34. A threaded block 35 is fixedly connected to the mounting rod 34. A threaded rod 36 is internally threadedly connected to the threaded block 35. One end of the threaded rod 36 is fixedly connected to a pressing block 37 for limiting the position of the sealing door 21. The other end of the threaded rod 36 is fixedly connected to an adjustment handle 38 for easy adjustment by the operator.

[0027] As a preferred technical solution in this embodiment: during actual use, the staff can control the connecting rod 33 to drive the threaded table 35 and the pressing table 37 to rotate until the pressing table 37 contacts the upper surface of the sealing door 21. At this time, the connecting rod 33 and the sealing door 21 are in a vertical state. Then the staff can control the adjusting handle 38 to drive the threaded rod 36 to rotate. During the rotation of the threaded rod 36, the pressing table 37 can be driven to move, thereby driving the sealing door 21 to move, so that the sealing door 21 can be tightly fitted with the connecting plate 13, avoiding heat overflow during use.

[0028] The technical effects brought about by the above embodiment are as follows: by providing the threaded rod 36 and the pressing platform 37, it is possible to effectively control the sealing door 21 and the connecting plate 13 to form a tight fit during use, effectively avoiding the situation in which a large amount of heat is lost in the kiln due to heat overflow during use, increasing energy consumption and reducing thermal efficiency.

[0029] The working principle of the above embodiment is:

[0030] 1. During actual use, when the kiln 1 is working, the staff can close the sealing door 21 to form a sealing effect on the kiln 1. When the sealing door 21 is closed, the connecting plate 13 is just located between the thermal expansion tube 23 and the sealing plate 22. Then the staff can heat up the kiln 1. After the kiln 1 is heated, the heat will be transferred to the sealing door 21 and the thermal expansion tube 23. When the thermal expansion tube 23 is heated, it will expand. After the thermal expansion tube 23 expands, it will achieve a tight fit effect on the four sides of the connecting plate 13, thereby effectively reducing heat overflow. When the sintering is completed, when the staff needs to open the sealing door 21, the pressure relief valve 25 can be controlled to discharge the hot air inside the thermal expansion tube 23. At this time, the thermal expansion tube 23 returns to its normal size. At this time, the staff can easily open the sealing door 21, avoiding the difficulty in opening and closing the sealing door 21 due to the expansion of the thermal expansion tube 23.

[0031] 2. During actual use, the staff can control the connecting rod 33 to drive the threaded table 35 and the pressing table 37 to rotate until the pressing table 37 contacts the upper surface of the sealing door 21. At this time, the connecting rod 33 and the sealing door 21 are in a vertical state. Then, the staff can control the adjustment handle 38 to drive the threaded rod 36 to rotate. During the rotation of the threaded rod 36, the pressing table 37 can be displaced, thereby driving the sealing door 21 to be displaced, so that the sealing door 21 can be tightly fitted with the connecting plate 13, avoiding the occurrence of heat overflow during use.

[0032] 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.
