Description

Technical Field

[0001] The present invention belongs to the technical field of detection of charging and firing containers for kilns, and particularly relates to a detection device for the sealing performance of saggers. Background Art

[0002] As is known in the industry, the integrity and sealing performance of saggers will directly affect the quality of product firing. By detecting the sealing performance of saggers, potential safety hazards can be discovered in a timely manner, various unfavorable situations caused by sagger rupture or poor sealing can be avoided, and product quality can be improved. In view of this, as a manufacturer using a kiln to fire products, it is usually necessary to detect saggers online, regularly or irregularly. Through detection, production interruptions and maintenance costs caused by sagger damage can be reduced, and production efficiency can be improved.

[0003] Still as is known in the industry, saggers used in kilns are usually opaque. In addition, in many cases, due to the internal micro-cracks in the saggers being concealed and the size of the micro-cracks being relatively small, it is difficult or even impossible to detect them with the naked eye. Using a detection device to detect the sealing performance of saggers can achieve the purpose of replacing manual detection with machines, and it is also the generally accepted detection method in the current industry. However, since this type of detection device belongs to the category of non-standard equipment, it is usually designed and manufactured by sagger users in their own ways, so the degree of technical reference is almost negligible, and the detection methods vary greatly depending on the detection device.

[0004] CN219830214U recommends "a detection mechanism for the sealing performance of saggers". This patent involves buckling two saggers, sealing the buckling part, and performing detection in a water tank. For the specific detection method, please refer to paragraphs 0019 and 0022 of the patent specification. Although this patent can achieve the detection purpose, perhaps due to the special structure of the sagger, such as the existence of a sagger fire groove, not only an installation plate but also an airbag are required. When the electric blower works, air is introduced into the sagger cavity. If bubbles are generated in the water tank, it indicates that there is a sealing problem with the sagger. This wet detection method using a water tank is troublesome in operation, for example, manual operation is required to fix the two saggers face to face. On the other hand, it is not conducive to protecting the environment of the detection site, such as causing the floor to be slippery. Moreover, the detection efficiency is relatively low, for example, each detection requires repeated manual clamping. In addition, after the sagger is detected in the water tank, the detected sagger needs to be dried, which takes a long time and cannot be detected online on a mass production furnace.

[0005] In the prior art, the main confusion in the industrial detection of saggers using compressed air lies in that: since the widths of the fire grooves of saggers such as ceramic saggers and graphite saggers are relatively wide, it is generally considered difficult to achieve good sealing during the detection process, thus affecting the accuracy of the detection. Especially for ceramic saggers, the dimensional error degrees of the respective fire grooves formed thereon (one fire groove each in the front, rear, left, and right directions) in the width direction are much larger than those of graphite saggers, and the dimensional consistency is very poor. Therefore, it is relatively difficult to manufacture 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 detecting the sealing performance of saggers, the seal needs to be covered on the open part of the sagger from top to bottom.

[0006] In view of the above prior art state, the applicant has conducted repeated and beneficial designs and simulation tests, and formed the technical solution to be introduced below. Summary of the Invention

[0023] In order to more clearly understand the technical essence and beneficial effects of the present invention, the applicant will make a detailed description in the following by way of examples. However, the descriptions of the examples are not limitations on the technical solutions of the present invention. Any equivalent transformation that is merely formal rather than substantial based on the concept of the present invention should be regarded as falling within the scope of the technical solutions of the present invention.

[0024] In the following description, all concepts related to directions or orientations such as up, down, left, right, front and back are based on Figure 1 the position state where it is located. Therefore, it cannot be understood as a special limitation on the technical solution provided by the present invention.

[0025] Please refer to Figure 1 , which shows a frame 1. The frame 1 is separately arranged on the floor of the test site in the use state, or can also be supported on the floor at the position of the sagger detection station of the sagger circulation mechanism between the inlet and outlet of the kiln furnace hearth accompanying the kiln furnace automatic production line. An electrical control box 11 is arranged on the lower left or right side of the frame 1. An installation frame 12 for a sagger airtightness detection mechanism is arranged at the upper part of the frame 1 in the height direction, and an installation frame 13 for a to-be-tested sagger conveying mechanism is arranged at a position corresponding to the lower part of the installation frame 12 for the sagger airtightness detection mechanism; it shows a to-be-tested sagger conveying mechanism 2. The to-be-tested sagger conveying mechanism 2 is arranged on the aforementioned installation frame 13 for the to-be-tested sagger conveying mechanism and is electrically connected to the aforementioned electrical control box 11; a sagger airtightness negative pressure detection mechanism 3.

[0026] As can be seen from the above description, there are two selectable settings for the scenario of the present invention. One is to be set independently, i.e., set in the sagger test site in a separate setting manner; the other is to be supported on the floor at the position of the sagger detection station of the sagger transfer machinery located between the inlet and the outlet of the kiln furnace hearth along with the automatic production line of the kiln furnace. Regarding the on-line detection of the latter, that is, regarding the second use scenario, the concept of the automatic production line of the kiln furnace is as follows: A frame group generally in the shape of ⊔ is set between the area of the inlet of the kiln furnace hearth (sagger inlet) at one end of the kiln furnace and the outlet of the kiln furnace hearth (sagger outlet) at the other end of the kiln furnace hearth. The two ends of the longitudinal part of the upper part of the ⊔ shape generally correspond to the inlet and the outlet of the kiln furnace hearth respectively. The sagger 4 after being loaded slowly enters from the inlet of the kiln furnace hearth and slowly moves forward and successively passes through each temperature zone in the hearth, such as the preheating zone, the heating zone, the heat preservation zone, the cooling zone and the cooling area until it exits from the outlet of the kiln furnace hearth, and successively goes through smashing (because many materials are in a stubborn caking state after firing), discharging, cleaning, sagger airtightness detection (the cleaning step can also be located after the sagger airtightness detection. If damaged and / or cracked saggers are found during the detection, they will be removed), sagger loading, leveling (leveling the materials in the sagger 4 to avoid the tower effect), and then enters the hearth from the inlet of the kiln furnace, and so on in a cycle. The foregoing workstations are completed on the frame group in the shape of ⊔, that is, on the automatic production line of the kiln furnace. Therefore, the foregoing second use scenario is to incorporate the present invention into the production line as the sagger detection station of the production line.

[0027] In this embodiment, the electrical control box 11 is set on the lower left side of the frame 1. However, if it is set on the lower right side of the frame 1, it should be regarded as an equivalent technical means and still belongs to the technical connotation scope disclosed by the present invention.

[0028] Continue to see Figure 1, as the technical key point of the technical solution provided by the present invention: the aforementioned crucible sealing negative pressure detection mechanism 3 includes a negative pressure suction device 31, an open-covering and closing device 32 for the crucible to be tested, and a fire groove sealing device 33 for the crucible to be tested.

The open-covering and closing device 32 for the crucible to be tested is connected to the crucible sealing detection mechanism mounting frame 12 at a position below the aforementioned crucible sealing detection mechanism mounting frame 12.

[0032] The applicant needs to explain that: in this embodiment, although the vacuum pressure gauge bracket 3241 together with the vacuum pressure gauge 324 is arranged on the left pipe beam 123, it is also possible to reasonably select a position and arrange it on the right pipe beam 124. Even after extending the air guide pipe 3231, the vacuum pressure gauge bracket 3241 can be arranged at other reasonable positions on the frame 1. Therefore, it cannot be considered that the technical connotation scope disclosed by the present invention is deviated due to the position change of the vacuum pressure gauge bracket 3241.

[0033] In this embodiment, the aforementioned sagger open-end closing gasket 322 is made of an elastomeric material. The aforementioned elastomeric material is rubber, and the aforementioned rubber can be natural rubber, nitrile rubber, asbestos rubber, or other equivalent materials.

[0034] Continue to see Figures 1 to 3, the aforementioned fire trough sealing device 33 for the test crucible includes a set of fire trough fixing block pressing cylinder actuators 331, a set of fire trough fixing block pressing plates 332, and a set of fire trough sealing sheets 333. The number of the set of fire trough fixing block pressing cylinder actuators 331 is four, and they are horizontally fixed on the upward side of the aforementioned crucible open-end closing support plate 321 corresponding to the actuator fixing holes 3212 ( Figure 3 shown) on the crucible open-end closing support plate 321, with one distributed in the front, back, left, and right respectively, and are electrically connected to the aforementioned electrical control box 11. The fire trough fixing block pressing cylinder columns 3311 of the set of fire trough fixing block pressing cylinder actuators 331 each protrude from the edge part of the outward side of the crucible open-end closing support plate 321. The number of the set of fire trough fixing block pressing plates 332 is equal to the number of the set of fire trough fixing block pressing cylinder actuators 331. The upper part of each fire trough fixing block pressing plate 332 faces one side of the fire trough fixing block pressing cylinder actuator 331 and is fixed to the aforementioned fire trough fixing block pressing cylinder column 3311 by a set of fire trough fixing block pressing plate pads 3321 with screws 33211. And on the lower part of the set of fire trough fixing block pressing plates 332 and on the side facing the set of fire trough sealing sheets 333, there is formed a fire trough sealing sheet fixing seat 3322 respectively. The number of the set of fire trough sealing sheets 333 is four, and they are respectively adhesively fixed to the inward side of the fire trough sealing sheet fixing seats 3322. And in the state of testing the aforementioned crucible 4, the fire troughs 42 formed at the front, back, left, and right upper edge parts of the crucible 4 are sealed by the set of fire trough sealing sheets 333 respectively.

[0035] In this embodiment, the aforementioned set of fire trough fixing block pressing cylinder actuators 331 is a pneumatic cylinder; the aforementioned set of fire trough sealing sheets 333 is made of an elastomeric material, and the aforementioned elastomeric material is rubber; the rubber described in this embodiment is natural rubber, but nitrile rubber or asbestos rubber can also be used.

[0036] When the aforementioned test crucible conveying mechanism 2 conveys the crucible 4 to be tested to the position below the test crucible open-end covering and closing device 32 of the structural system of the crucible airtightness negative pressure detection mechanism 3 and the test crucible conveying mechanism 2 lifts the crucible 4 upward (to be described below), that is, jacks it up, the upper open end of the crucible 4, that is, the upper open end of the crucible cavity 41 of the crucible 4, is closely attached to the downward side surface of the crucible open-end closing pad 322. Thus, the aforementioned upper open end of the crucible 4 is closed by the crucible open-end closing pad 322 with a covering effect. At the same time, under the instruction issued by the aforementioned electrical control box 11, the set of fire trough fixing block pressing cylinder actuators 331 work synchronously, causing the fire trough fixing block pressing cylinder columns 3311 to displace into the cylinder body, driving the set of fire trough fixing block pressing plates 332 to move inward accordingly, that is, towards Figure 2The directional displacement of the sagger 4 shown is driven by a set of fire trough fixing block pressing plates 332 due to the fixing of a set of fire trough plugging and sealing pieces 333 to the fire trough fixing block pressing plate pads 3321 at the lower part of the fire trough fixing block pressing plates 332. Thus, the set of fire trough plugging and sealing pieces 333 are driven to displace in the direction of the sagger 4, and then the fire trough 42 of the sagger 4 ( Figure 2 shown) is sealed. Then, under the instruction of the electric control box 11, the motor 3111 operates, driving the negative pressure fan 311. During the operation of the negative pressure fan 311, the air in the sagger cavity 41 is evacuated through the air suction pipe 312, that is, the air in the sagger cavity 41 passes through the sagger open-end sealing gasket hole 3222, the sagger open-end sealing gasket support plate air outlet hole 3211, the air suction pipe 312, the air inlet of the negative pressure fan 311, the air outlet of the negative pressure fan 311, the exhaust pipe 313 and the dust filter 3131 and is discharged to the outside. When the negative pressure in the sagger cavity 41 reaches the set value of the vacuum pressure gauge 324, the motor 3111 stops operating. The sagger cavity 41 is in a pressure-holding state. If there are cracks in the sagger 4 that cause air leakage, the on-site staff can observe the decrease in the reading of the vacuum pressure gauge 324, indicating that the sagger 4 is not suitable for further use and should be removed. Otherwise, it means the sagger 4 is intact and can be continuously used. The time for the above pressure-holding is usually only a few seconds or more than ten seconds. After the detection is completed, the actuating cylinder 331 of the set of fire trough fixing block pressing plates operates in the reverse direction, releasing the sealing of the fire trough 42 of the sagger 4 by the set of fire trough plugging and sealing pieces 333. Then, the structure system of the above-mentioned sagger to be tested conveying mechanism 2 and the sagger to be tested lifting device 27 described below descends, releasing the sagger 4 onto a set of saggers to be tested conveying rollers 21. At the same time, the sagger to be tested travel channel lifting gate roller 285 of the sagger to be tested travel channel opening and closing device 28 descends, so that the sagger 4 that has completed the detection can move out, and the next sagger to be tested 4 is positioned below the sagger open-end covering and sealing device 32. The above process is continuously repeated in this way.

[0040] Taking the second scenario of the foregoing setup scenario as an example, when the sagger 4 to be detected is fed, i.e., sent, to a set of sagger conveying rollers 21 of the sagger conveying mechanism 2 to be tested of the present invention by a sagger feeding mechanism (not shown in the figure), since the sagger conveying roller driving motor 261 of the structural system of the sagger conveying roller driving device 26 to be tested is in a working state at this time, the sagger conveying roller driving motor 261 drives the sagger conveying roller driving reduction gearbox 262. After being decelerated by the sagger conveying roller driving reduction gearbox 262, the final power output shaft 2621 of the sagger conveying roller driving reduction gearbox drives the right shaft head 212 of one of the sagger conveying rollers in a set of sagger conveying rollers 21 that is in transmission connection with it. The right shaft head 212 of the sagger conveying roller drives one of the sagger conveying rollers in a set of sagger conveying rollers 21, and the left shaft head 211 of the sagger conveying roller driven by the driven sagger conveying roller causes all of the set of sagger conveying rollers 21 to enter a rotating state in a chain reaction manner under the combined action of the sagger conveying roller double-row sprocket 214 and the sagger conveying roller double-row sprocket transmission chain 2141. When the sagger 4 is moved by the movement of the set of sagger conveying rollers 21 to the extent that the signal can be collected by the aforementioned sagger in-position signal collector 254, the sagger 4 is exactly below the aforementioned sagger opening sealing pad 322. Then the sagger in-position signal collector 254 feeds the signal back to the electrical control box 11, and the electrical control box 11 issues a working instruction to the sagger travel channel opening and closing device 28. The sagger travel channel lifting gate roller driving cylinder 282 works, and the sagger travel channel lifting gate roller driving cylinder column 2821 that extends out of the cylinder body, i.e., upward, drives the sagger travel channel lifting gate roller seat 284 and the sagger travel channel lifting gate roller 285 to rise from the gap (space) between two adjacent sagger conveying rollers 21 to prevent the sagger 4 from moving forward. At the same time, the electrical control box 11 issues an instruction to the aforementioned sagger conveying roller driving device 26 to stop the sagger conveying roller driving motor 261. Under the working instruction issued by the electrical control box 11, the left and right clamping devices 24 and 25 for centering the sagger to be tested work synchronously. Taking the right clamping device 25 for centering the sagger to be tested as an example, the sagger centering clamping plate driving cylinder 251 works, and the sagger centering clamping plate driving cylinder column 2511 that extends out to the left, i.e., out of the cylinder body, drives the sagger centering clamping plate 252 to move leftward and clamp the sagger in cooperation with the corresponding sagger centering clamping plate of the left clamping device 24 for centering the sagger to be tested. After clamping, i.e., after one clamping action, the centering of the sagger 4 is completed. Then, after a reasonable delay time set by the process, such as 2 to 3 seconds, it is immediately released, that is, the sagger centering clamping plate driving cylinder 251 works in the reverse direction, and the sagger centering clamping plate driving cylinder column 2511 and the sagger centering clamping plate 252 are reset to the right.Meanwhile, under the working instruction issued by the electrical control box 11, the test sagger lifting actuator 272 also enters the working state. The column 2721 of the test sagger lifting actuator extends upward, i.e., outward of the cylinder body, and pushes the test sagger frame fixing plate 275 together with a pair of test sagger lifting frames 276 fixed thereon to rise from the gap between two adjacent test sagger conveying rollers 21, so that the upper edge surface of the open mouth of the sagger 4 is in close contact with the sagger open mouth sealing pad 322 to form a seal. Then, according to the operation process described by the applicant above, it is detected by the sagger sealing negative pressure detection mechanism 3. After the detection is completed, the aforementioned test sagger lifting device 27 works in reverse, causing a pair of test sagger lifting frames 276 to descend, and placing the sagger 4 that has completed the detection on a group of test sagger conveying rollers 21, and conveying the sagger 4 that has completed the detection to the next working station in the state where the test sagger traveling channel lifting gate roller 285 of the test sagger traveling channel opening and closing device 28 descends to open the channel. Of course, if the sagger 4 has cracks and air leakage, it is removed according to what the applicant described above.

[0041] In summary, the technical solution provided by the present invention makes up for the deficiencies in the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the technical effect column above.
