Description

Technical Field

[0001] The invention relates to the technical field of leakage detection, and in particular to leakage detection equipment for a sintering furnace. Background Art

[0002] Sintering furnace is a kind of furnace that makes the solid particles of ceramic green body bond to each other at high temperature, so that the grain grows, the voids (pores) and grain boundaries gradually decrease, and through the transfer of substances, the total volume shrinks, the density increases, and finally becomes a dense polycrystalline sintered body with a certain microstructure. Sintering furnace is mainly used for the sintering of ceramic powder, ceramic inserts and other zirconia ceramics, the sintering of diamond saw blades, and can also be used for heat treatment such as copper material and plate strip annealing. It can also be used for high temperature sintering and heat treatment of thick film circuits, thick film resistors, electronic component electrodes, LTCC, steel heaters, solar panels and other similar products. It is mainly used in the steel industry, metallurgical industry, new materials industry, etc.

[0003] Since the sintering furnace consumes a lot of power, it also needs to be used with a larger voltage and current. In order to achieve safe production, it is necessary to perform leakage detection on the equipment to protect the normal use of the equipment and the life safety of the staff. The commonly used leakage detection and protection device is the leakage protector, but the traditional leakage protector lacks an anti-overheating component. When the indoor temperature is too high, because the leakage protector itself will generate some energy when working, coupled with the influence of the external environment, the temperature in the leakage protector cabinet will increase sharply. Excessive temperature will cause the leakage protector to burn out and affect its normal operation. In addition, the current leakage protector has poor shock resistance. If it is vibrated, the performance of the device itself may decline, thereby affecting the normal operation of the equipment and even causing accidents. Therefore, we need to propose a leakage detection device for sintering furnaces with overheat protection. Summary of the invention

[0059] The present invention arranges a shockproof mechanism 5 including a fixing plate 501 and a bracket 502 inside the shell 1, and the two ends of the connecting rod 14 slidably inserted on the fixing plate 501 are fixedly connected to the bracket 502 and the pull rod 15 respectively. The bracket 502 is arranged in a U shape to fix and clamp the detection device body 4. A compression spring 16 is sleeved on the connecting rod 14, and a rubber pad 17 is arranged on the contact surface between the bracket 502 and the detection device body 4, so that the detection device body 4 will not shake or fall off easily, and a good protection effect is formed on the detection device body 4, avoiding vibration to cause damage to the detection device body 4 and affect normal operation, and preventing vibration from causing the detection device body 4 and the wire to fall off and lose the leakage detection function.

[0060] The temperature sensor 6 is connected to the cooling fan 702 in the overheating prevention mechanism 7 by signal. In actual use, the detection temperature threshold of the temperature sensor 6 can be set to 40°C so that the detection device body 4 can work better.

[0061] The model of air cooler 702 can be SAC-25D, and its specific parameters are: voltage 220V, cooling capacity 2.5KW, operating current 4.2A, air volume 340m 3 / H, power 0.88KW;

[0062] The rubber pad 17 is made of polyurethane rubber, which has excellent wear resistance, high strength, good elasticity, good cushioning and shock absorption in the hardness range of Shore A60 to Shore A70, the higher the vibration frequency, the greater the energy absorption, good oil resistance and chemical resistance, low affinity with non-polar mineral oil, almost no corrosion in fuel oil and machine oil, high friction coefficient, and can also be replaced with nitrile rubber materials according to actual conditions;

[0063] The absorbent cotton net 23 is made of absorbent resin material, which has a high water absorption function of absorbing water hundreds to thousands times heavier than itself and has excellent water retention performance. Once it absorbs water and swells into hydrogel, it is difficult to separate the water even under pressure, thus preventing the equipment from getting damp.

[0064] When in use, the slide cover 2 is opened, and the pull rod 15 is pulled to increase the distance between the two groups of brackets 502, and the detection device body 4 is fixed between the two groups of brackets 502, so that the brackets 502 clamp and fix the detection device body 4, and the detection device body 4 is installed by fixing screws.

The value is transmitted to the air cooler 702, and the air cooler 702 extracts the outside air and cools it down, and then blows it into the inside of the housing 1 through the air outlet 19, so as to cool down the working environment of the detection device body 4, and form an external air circulation through the ventilation holes 8 on the two side walls of the housing 1, which can effectively prevent the detection device body 4 from overheating, avoid the detection device body 4 from being burned out due to excessive temperature, extend the service life of the device, and provide a good working environment for the sintering device, so that the detection device body 4 can stably and effectively detect the circuit;

When the device is subjected to an accidental collision or the like, the two ends of the detection device body 4 are clamped by two groups of U-shaped brackets 502, and the compression spring 16 can buffer and offset the external force, so that the detection device body 4 will not shake or fall easily, thus forming a good protection for the detection device body 4, avoiding damage to the detection device body 4 caused by vibration and affecting normal operation, and preventing the detection device body 4 and the wire from falling off and losing the leakage detection function due to vibration.

[0067] Three groups of ventilation holes 8 are equidistantly provided on the two side walls of the shell 1, and a sleeve 22 is inserted inside the ventilation hole 8. A dust filter 23 and a water-absorbing cotton net 24 are arranged inside the sleeve 22 in sequence. On the one hand, the dust filter 23 and the water-absorbing cotton net 24 can prevent external water stains and dust from entering the shell 1 and affecting the use of the detection device body 4 when ventilating the inside of the shell 1; on the other hand, when the overheating prevention mechanism 7 is in use, condensed water formed by the cooling of hot air can be absorbed to prevent condensed water from causing equipment failure; and by respectively arranging a limit ring 25 and a locking screw ring 26 at both ends of the sleeve 22, the installation, use, disassembly and replacement of the sleeve 22 can be facilitated, which has high convenience and greatly improves the practicability and use range of the device.

[0068] Mounting seats 20 are arranged at both ends of the shell 1, and mounting holes 21 are arranged on the mounting seats 20.

[0069] The detection device body 4 is connected to the sintering furnace circuit through the terminal 28 and the wire. The temperature sensor 6 detects the temperature inside the box and transmits the detected value to the single-chip microcomputer 31 in the monitoring module 30. When the temperature exceeds the set value, the single-chip microcomputer 31 controls the execution switch 29 to disconnect the circuit and starts the high-decibel speaker 3 to remind the staff to perform maintenance, which has a good protection effect on the equipment; the zero-sequence mutual inductor 32 in the monitoring module 30 can detect abnormal leakage current and send a signal to the amplification link. After receiving the signal, the amplification link amplifies the leakage signal and transmits it to the single-chip microcomputer 31 , and start the execution switch 29, immediately disconnect the main switch of the circuit, and start the high-decibel speaker to warn, to prevent people from getting close to the contact and causing casualties, and wait for the staff to carry out maintenance; the humidity sensor 33 in the monitoring module 30 can detect the humidity inside the equipment.
