Description

Technical Field

[0001] This utility model relates to the field of ceramic technology, specifically a ceramic kiln. Background Technology

[0002] Ceramic kilns are key thermal equipment used for firing ceramic products. Their history can be traced back to the Neolithic Age. Over thousands of years, they have evolved from early updraft kilns and dome kilns to modern tunnel kilns, shuttle kilns, roller kilns, and many other types. By precisely controlling the temperature (which can reach hundreds to thousands of degrees Celsius), firing atmosphere (oxidation, reduction, etc.), and time, the ceramic body undergoes physicochemical changes to form ceramic products with specific properties. Glaze color, texture, hardness, and other characteristics are all closely related to the firing regime of the kiln.

[0003] Chinese patent application number CN202421920942.7 discloses a high-efficiency and energy-saving ceramic craft firing kiln, comprising: a kiln body. The beneficial effects of the above-mentioned utility model are: by setting up a kiln car and a firing rack, the kiln car can be pulled out of the kiln body. The kiln car is assisted by the guide rollers on the top of the guide support plate, and the kiln car and firing rack are pulled out, making it convenient to place the ceramics to be fired on the firing rack. The inner top block on the inside of the kiln door pushes and fixes the position of the kiln car in the kiln body, and the kiln car and firing rack are stably placed in the kiln body, improving the stability of the position during ceramic firing. By setting up a heat preservation box and a heat exchange copper gas pipe, the high-temperature flue gas in the heat preservation box is heated by the gas treated by the oxygen enrichment device in the heat exchange copper gas pipe, and the temperature of the combustion gas is increased. It is mixed with the gas supplied by the gas pipe in the centralized gas box, sprayed out through the ventilation box and combustion nozzle, and ignited by the ignition rod, and the ceramics are fired by the fuel.

[0004] However, existing technology lacks monitoring of thermal expansion and contraction when the temperature inside the kiln changes. The contact between the top block and the kiln car may become loose, and the kiln car is prone to displacement due to vibration or airflow impact, affecting the positional stability during ceramic firing.

[0005] In summary, this utility model provides a ceramic kiln to solve the above-mentioned problems. Utility Model Content

[0006] This invention provides a ceramic kiln that solves the problem in the prior art where the lack of monitoring of thermal expansion and contraction affects the positional stability of ceramic firing by incorporating a component that monitors the thermal expansion and contraction of the kiln.

[0007] The specific technical solution of this utility model is as follows:

[0008] A ceramic kiln includes a kiln body, a support is provided on the side of the kiln body, side plates are rotatably connected to both sides of the support, a spring is fixedly connected to the side plate near the support, an inclined block is fixedly connected to the end of the spring away from the side plate, a sliding column is fixedly connected to one side of the inclined block, and a bonding plate is fixedly connected to the side of the sliding column away from the inclined block.

[0009] In this invention, the kiln body can be a ceramic kiln commonly used in the prior art, and the whole is made of metal shell; the bonding plate is always in close contact with the outer wall of the kiln by spring elasticity to ensure continuous monitoring; the bracket is connected to the kiln body or surrounding components to determine the monitoring position.

[0010] In a preferred embodiment, the side of the inclined block away from the sliding column is triangular in shape, and a limiting plate is rotatably connected to the side of the side plate away from the sliding column. The end of the limiting plate away from the side plate is slidably connected to the inclined surface of the inclined block.

[0011] In a preferred embodiment, a transmission frame is rotatably connected to the top of the side plate, and a pressure groove is formed on the side of the transmission frame away from the side plate.

[0012] In a preferred embodiment, trigger buttons are fixedly connected to both sides of the top of the bracket, and the size of the trigger buttons is adapted to the pressure groove.

[0013] In a preferred embodiment, a prompter is fixedly connected to the top center of the bracket, and the prompter is electrically connected to a trigger button.

[0015] In a preferred embodiment, the bracket has a sliding groove on the side near the trapezoidal plate, and the trapezoidal plate is slidably connected to the sliding groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model ensures detection reliability by combining elastic bonding with mechanical transmission. The bonding plate is always in close contact with the outer wall of the kiln through spring elasticity, ensuring continuous monitoring. Moreover, the displacement of the bonding plate is amplified by multi-stage mechanical transmission, converting the expansion into a perceptible signal, improving detection sensitivity, and avoiding missed detection problems caused by poor contact or small displacement.

[0018] 2. This utility model improves safety response efficiency through an automated early warning mechanism. The trigger button and the indicator are linked by electrical signals, and an alarm is triggered immediately when there is abnormal expansion, without the need for manual intervention, thus shortening the fault detection time. At the same time, through the design of preset thresholds, it can achieve no interference in normal state and accurate alarm in abnormal state, reducing false alarms and improving the reliability of early warning.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] like Figure 1-5 As shown, this utility model provides a ceramic kiln, including a kiln body 12. A support 1 is provided on the side of the kiln body 12. Side plates 2 are rotatably connected to both sides of the support 1. A spring 3 is fixedly connected to the side plate 2 near the support 1. An inclined block 4 is fixedly connected to the end of the spring 3 away from the side plate 2. A sliding column 5 is fixedly connected to one side of the inclined block 4. A bonding plate 6 is fixedly connected to the side of the sliding column 5 away from the inclined block 4.

[0027] The side of the inclined block 4 away from the sliding column 5 is triangular in shape. The side plate 2 away from the sliding column 5 is rotatably connected to the limiting plate 7. The end of the limiting plate 7 away from the side plate 2 is slidably connected to the inclined surface of the inclined block 4.

[0028] A transmission frame 8 is rotatably connected to the top of the side plate 2, and a pressure groove 81 is provided on the side of the transmission frame 8 away from the side plate 2.

[0029] Trigger buttons 9 are fixedly connected to both sides of the top of bracket 1. The size of trigger buttons 9 is adapted to the pressure groove 81.

[0030] A prompter 10 is fixedly connected to the top center of the bracket 1, and the prompter 10 is electrically connected to the trigger button 9.

[0031] A trapezoidal plate 82 is fixedly connected to the bottom of the transmission frame 8.

[0032] A groove 11 is provided on the side of the bracket 1 near the trapezoidal plate 82, and the trapezoidal plate 82 is slidably connected to the groove 11.

[0033] The working principle of this utility model is as follows: when the kiln body 12 expands due to temperature changes, its outer wall will push the bonding plate 6 outward; the bonding plate 6 drives the inclined block 4 to move away from the kiln body 12 through the sliding column 5; the side of the inclined block 4 away from the sliding column 5 is a triangular inclined surface, and its movement will squeeze the end of the limiting plate 7 away from the side plate 2. Since the limiting plate 7 is rotatably connected to the side plate 2, the squeezing action will force the side plate 2 to rotate around the rotation connection point of the support 1.

[0034] When the side plate 2 rotates, its top end drives the transmission frame 8 to move synchronously. The trapezoidal plate 82 at the bottom of the transmission frame 8 slides along the slide groove 11 of the bracket 1, ensuring that the transmission frame 8 moves smoothly and the direction of movement is controlled. The pressure groove 81 on the transmission frame 8 gradually approaches the trigger button 9 at the top of the bracket 1 as the transmission frame 8 moves. Under normal expansion range, the pressure groove 81 and the trigger button 9 remain in a non-contact state. When the expansion exceeds the safety threshold, the pressure groove 81 contacts the trigger button 9 and applies pressure. The trigger button 9 converts the mechanical signal into an electrical signal.

[0035] Spring 3 connects side plate 2 and inclined block 4, providing elastic restoring force when the kiln shrinks or displacement decreases, so that the bonding plate 6 always adheres tightly to the outer wall of the kiln body 12, ensuring continuous monitoring; after the trigger button 9 is triggered, the electrical signal is transmitted to the indicator 10, and the indicator 10 starts the warning, prompting the staff to detect abnormal kiln expansion; the slide 11 limits the trapezoidal plate 82, ensuring that the transmission frame 8 moves only in the preset direction, avoiding false triggering or structural damage caused by shaking.

[0036] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
