Description

Technical Field

[0001] The utility model relates to the technical field of triethylene glycol cleaning furnaces, in particular to an automatic decompression type triethylene glycol cleaning furnace. Background Art

[0002] Triethylene glycol is a chemical substance that is miscible with water, ethanol, benzene, and toluene, but poorly soluble in ethers, insoluble in petroleum ether, and hygroscopic. It has an oxygen atom and a hydroxyl group attached to an alkyl group, thus possessing the properties of both alcohol and ether.

[0003] When cleaning workpieces with polyester contaminants, the existing triethylene glycol cleaning furnace needs to first heat the triethylene glycol solution in the furnace to boiling. After the triethylene glycol solution boils, a large amount of steam is generated, and the accumulation of steam will form high pressure in the cleaning furnace. Although the cleaning furnace has a pressure relief function, it is all manual pressure relief. Therefore, the operator needs to perform manual pressure relief treatment at regular intervals, which is not only time-consuming and labor-intensive, but also may cause production accidents if the operator is negligent. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an automatic decompression type triethylene glycol cleaning furnace, which solves the problem that in the existing triethylene glycol cleaning furnace, when cleaning workpieces with polyester dirt adhered to them, the triethylene glycol solution in the furnace needs to be heated to boiling first. After the triethylene glycol solution boils, a large amount of steam will be generated, and the accumulation of steam will form high pressure in the cleaning furnace. Although the cleaning furnace has a pressure relief function, the pressure relief is all done manually, so the operator needs to perform manual pressure relief at regular intervals, which is not only time-consuming and labor-intensive, but also may cause production accidents if the operator is negligent.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The top of the cleaning chamber is provided with a bottom plate, and the top of the cleaning chamber is provided with a top cover, and the top of the top cover is provided with a pressure relief device, and the pressure relief device and the top cover are connected. The pressure relief device includes a pressure relief cylinder, a conical pressure relief port is opened at the center of the bottom end of the pressure relief cylinder, an exhaust hole is opened at the center of the top end of the pressure relief cylinder, an inner cylinder is provided inside the pressure relief cylinder, an air inlet is opened at the center of the bottom end of the inner cylinder, and an air outlet is opened at the center of the top end of the inner cylinder, a slide groove is opened on both sides of the inner cylinder, symmetrical mounting plates are provided on both sides of the inner cylinder, a sliding rod is provided between the symmetrical mounting plates, a sliding rod is slidably connected to the sliding rod, a spring is provided on the sliding rod and located on one side of the sliding rod, a connecting plate is provided on one side of the sliding rod, a limiting block is provided on one side of the connecting plate, the connecting plate and the slide groove are movably connected, and a conical blocking block is provided at the bottom end of the limiting block.

[0007] Preferably, the limiting block and the air inlet are movably connected, and the conical blocking block and the conical pressure relief port are cooperatively connected.

[0008] Preferably, the inner top end of the pressure relief cylinder and the top end of the inner cylinder are connected via a damper, and a damping spring is provided on the periphery of the damper.

[0009] Preferably, a symmetrical fixing block is provided at the inner bottom end of the pressure relief cylinder, a slot is provided at the top end of the fixing block, and a clamping block corresponding to the slot is provided at the bottom end of the inner cylinder, and the clamping block and the slot are fitted and connected.

[0010] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0011] The utility model provides an automatic decompression type triethylene glycol cleaning furnace by setting a pressure relief device. When the temperature in the cleaning furnace body rises and the pressure increases, the pressure acts on the conical blocking block. When the thrust generated by the pressure is greater than the damper, the damping spring and the force of the spring contraction, the conical blocking block is pushed up by the pressure and leaves the conical pressure relief port. At the same time, it also drives the slider to move on the slide rod and squeezes the spring, so that the pressure can be relieved through the conical pressure relief port, the air outlet and the exhaust hole. At the same time, the inner cylinder exerts pressure on the damper and the damping spring. At this time, the block leaves the fixed block. The slot opened allows pressure relief through the gap between the inner wall of the pressure relief cylinder and the outer wall of the inner cylinder, thereby greatly increasing the pressure relief space and accelerating the pressure relief process. After the pressure relief is completed, due to the action of the damper and the damping spring, the inner cylinder will return to its initial position, and the card block will cooperate and connect with the slot on the fixed block. At the same time, due to the elastic potential energy of the spring, the slider moves downward on the slide rod until the conical barrier block and the conical pressure relief port are cooperated and connected, ensuring that the gas will not be discharged, thereby realizing automatic pressure relief processing, saving time and effort, and avoiding production accidents.

[0020] Example 2:

[0021] As shown in the attached figure of the instruction manual Figure 1 、 Figure 2 and Figure 3As shown, an automatic decompression type triethylene glycol cleaning furnace is used. When the temperature inside the cleaning furnace body 1 rises and eventually reaches the boiling point, steam is generated. When the pressure value generated by the steam inside the cleaning furnace body 1 becomes larger and larger, the pressure will act on the conical barrier block 19. When the thrust generated by the pressure is greater than the force when the damper 6, the damping spring 7 and the spring 14 contract, the conical barrier block 19 is pushed upward by the pressure and leaves the conical pressure relief port 23.

At the same time, the inner cylinder 8 will apply pressure to the damper 6 and the damping spring 7. At this time, the block 20 leaves the slot 22 opened on the fixed block 21, so that the pressure can be relieved through the gap between the inner wall of the pressure relief cylinder 5 and the outer wall of the inner cylinder 8, thereby greatly increasing the pressure relief space and accelerating the pressure relief process.
