Description

Technical Field

[0001] The invention belongs to the technical field of detection of charging and firing containers for kilns, and in particular relates to a sagger sealing detection device. Background Art

[0002] As is known in the industry, the integrity and sealing of the sagger will have a direct impact on the quality of product firing. By testing the sealing of the sagger, potential safety hazards can be discovered in time, and various undesirable adverse situations caused by sagger rupture or poor sealing can be avoided, thereby improving product quality. In view of this, manufacturers who use kiln to fire products usually need to test the sagger online, regularly or irregularly. Through testing, production interruptions and maintenance costs caused by sagger damage can be reduced, and production efficiency can be improved.

[0003] As is known in the industry, kiln saggers are usually opaque. In addition, in many cases, the microcracks in the saggers are hidden inside and the size of the microcracks is relatively small, so it is difficult or even impossible to detect them with the naked eye. Using a detection device to detect the sealing of the sagger can achieve the purpose of replacing people with machines, and it is also the commonly accepted detection method in the industry. However, since this detection device belongs to the category of non-standard equipment, it is usually designed and produced by the sagger manufacturer in a variety of ways, so the degree of reference from a technical perspective is almost negligible, and the detection methods vary greatly with different detection devices.

[0004] CN219830214U recommends "a kind of sagger sealing detection mechanism". The patent is to buckle two saggers, implement sealing at the buckle, and place them in a water tank for detection. The specific detection method can be found in the patent specification paragraph 0019 and paragraph 0022. Although the patent can achieve the detection purpose, it may be due to the particularity of the sagger structure, such as the existence of the sagger fire tank, not only the installation plate is required, but also the air bag, etc., to draw air into the sagger cavity under the operation of the electric blower. If bubbles are generated in the water tank, it indicates that there is a sealing problem in the sagger. This wet detection by means of the water tank is troublesome to operate on the one hand, for example, manual operation is required to fix the two saggers face to face, and on the other hand, it is not conducive to ensuring the environment of the detection site, for example, it is easy to cause the floor to be slippery, and on the other hand, the detection efficiency is relatively low, for example, each detection must be repeatedly clamped by manual operation. In addition, after the water tank detects the sagger, it is necessary to dry the sagger that has completed the detection, which takes a long time, and it is impossible to do online detection on the mass production furnace.

[0005] In the existing technology, the confusion in the industry about the use of pressure air for testing saggers is mainly manifested as follows: since the width of the fire grooves of saggers such as ceramic saggers and graphite saggers is relatively wide, it is generally believed that it is difficult to implement a good seal during the detection process, thereby affecting the accuracy of the detection. In particular, the saggers made of ceramic materials have a much larger dimensional error in the width direction of the fire grooves (one each for the front, rear, left and right) formed thereon than the graphite saggers, and the dimensional consistency is very poor, so it is difficult to make rubber seals or sponge seals, and the sealing effect is not ideal and the seals are easily worn, which affects the sealing effect. Because when testing the sealing of the sagger, it is necessary to cover the open part of the sagger from top to bottom.

[0006] In view of the above-mentioned existing technical status, the applicant has conducted repeated and beneficial design and simulation tests and formed the technical solution to be introduced below. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to more clearly understand the technical essence and beneficial effects of the present invention, the applicant provides a detailed description in the form of embodiments below. However, the description of the embodiments is not a limitation of the present invention. Any equivalent changes made based on the concept of the present invention that are merely formal and not substantial should be regarded as within the scope of the technical solution of the present invention.

[0021] In the following description, all concepts related to up, down, left, right, front and back directions or orientations are based on Figure 1 The position state is taken as an example, and thus it cannot be understood as a special limitation on the technical solution provided by the present invention.

[0022] See also Figure 1 , showing a frame 1, which is separately arranged on the floor of the test site when in use, and can also be supported on the floor at the position of the sagger detection station of the sagger circulation mechanism located between the kiln furnace inlet and the kiln furnace outlet of the kiln automatic production line, an electrical control box 11 is arranged on the left or right side of the lower part of the frame 1, a sagger sealing detection mechanism mounting frame 12 is arranged on the upper part of the frame 1 in the height direction, and a sagger conveying mechanism mounting frame 13 to be tested is arranged at a position corresponding to the position below the sagger sealing detection mechanism mounting frame 12; showing a sagger conveying mechanism 2 to be tested, which is arranged on the aforementioned sagger conveying mechanism mounting frame 13 to be tested and is electrically connected to the aforementioned electrical control box 11; a sagger sealing negative pressure detection mechanism 3.

Relative to the latter online detection, that is, relative to the second usage scenario, the concept of the kiln automation production line is: a frame group roughly in the shape of a letter "⊔" is set between the kiln furnace entrance (sagger entrance) at one end of the kiln and the kiln furnace row exit (sagger row exit) at the other end of the kiln furnace, and the two ends of the upper longitudinal part of the letter "⊔" roughly correspond to the kiln furnace entrance and row exit, respectively. The loaded sagger 4 slowly enters from the furnace entrance of the kiln and moves slowly through the temperature zones in the furnace, such as the preheating zone, the heating zone, the insulation zone, the cooling zone and the cooling zone, until it exits from the furnace exit of the kiln, and is successively crushed (because many materials are in a stubborn agglomerate state after firing), poured, cleaned, and tested for sagger tightness (the cleaning step can also be placed after the sagger tightness test. If the sagger is damaged and / or cracked, it will be removed after the test), sagger loading, leveling (level the material in the sagger 4 to avoid the tower effect), and then enters the furnace from the kiln entrance, and the cycle continues. The aforementioned stations are completed on the ⊔-shaped rack group, i.e., the kiln automatic production line, so the aforementioned second usage scenario is to involve the present invention in the production line as a sagger detection station of the production line.
