Description

Technical Field

[0001] This application relates to the field of surge arrester manufacturing equipment technology, and in particular to a high-temperature vulcanization device for surge arrester insulating jackets. Background Technology

[0002] Rubber vulcanizing machines are commonly used equipment in the production of outer rubber protective sleeves for zinc oxide surge arresters. During the high-temperature vulcanization process of the surge arrester's insulating jacket, common vulcanizing equipment can easily produce gases with irritating odors, which can irritate the respiratory tract of operators. Prolonged inhalation of these gases can have a certain impact on the operator's health.

[0003] For example, Chinese patent application number CN201920198578.0 discloses a vulcanizing machine for producing zinc oxide surge arresters, including a vulcanizing machine body, an upper fixed plate, a lower fixed plate, an upper heating plate and a lower heating plate, as well as a first fixed plate, a suction fan, an absorption box, a first connecting pipe, a three-way pipe, a second connecting pipe and a first suction flare. An exhaust port is provided at the top of the absorption box, and an activated carbon adsorption layer is provided inside the absorption box. It also includes a second fixed plate, a third fixed plate, a first hydraulic rod, a second hydraulic rod, a third hydraulic rod and a fourth hydraulic rod, as well as a second suction flare. A switching valve is provided at the bottom output end of the three-way pipe.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] Because the upper and lower heating plates generate a large amount of pungent odor gas between them during the heating process, and the gas spreads immediately, simply adding a few suction vents near the vulcanizing machine can only remove a small portion of the pungent odor gas. Most of the pungent odor gas will still spread into the production workshop, and the treatment of the pungent odor gas is not thorough enough. Utility Model Content

[0006] This application provides a high-temperature vulcanization device for the insulating jacket of a surge arrester to improve the following technical problems:

[0007] Adding only a few suction vents near the main body of the vulcanizing machine can only remove a small portion of the irritating odor gas. Most of the irritating odor gas will still diffuse into the production workshop, and the treatment of the irritating odor gas is not thorough enough.

[0008] This application provides a high-temperature vulcanization device for the insulating jacket of a surge arrester, which adopts the following technical solution:

[0009] A high-temperature vulcanization device for a surge arrester insulating jacket includes a base, a gantry frame, a lifting mechanism, an upper heating plate, and a lower heating plate. The gantry frame is mounted on the base, the lower heating plate is fixed to the upper surface of the base, the lifting mechanism is mounted on the top of the gantry frame, and the upper heating plate is fixed to the bottom of the lifting mechanism. The lifting mechanism is used to drive the upper heating plate to rise and fall. A horizontally arranged sealing ring plate is fixed around the periphery of the upper heating plate. A retractable elastic sealing cover is provided at the bottom of the sealing ring plate. The bottom of the retractable elastic sealing cover cooperates with the upper surface of the base to form a sealed chamber. The lower half of the upper heating plate and the lower heating plate are located in the sealed chamber. An exhaust pipe is provided on the base to exhaust irritating gases from the sealed chamber. The outer end of the exhaust pipe is also connected to a waste gas treatment mechanism.

[0010] In one feasible technical solution of this application, a vertically arranged fixing plate is provided on the inner side of the sealing ring plate. The fixing plate surrounds and fits around the periphery of the upper heating plate, and the fixing plate is fixed to the side of the upper heating plate by bolts.

[0011] In one feasible technical solution of this application, a detachable connecting assembly is provided between the bottom of the retractable elastic sealing cover and the base, and the detachable connecting assembly is used to seal the bottom of the retractable elastic sealing cover with the upper surface of the base.

[0012] In one feasible technical solution of this application, the detachable connection assembly includes a connecting ring and multiple sets of spaced electromagnets. The connecting ring is horizontally arranged and connected to the bottom of the retractable elastic sealing cover. The electromagnets are embedded and fixed in the base. Each side of the lower heating plate has 2-5 sets of electromagnets. The connecting ring is made of ferromagnetic material and the electromagnets are used to magnetically fix the connecting ring.

[0013] In one feasible technical solution of this application, a sealing ring is sandwiched between the lower surface of the connecting ring and the upper surface of the base.

[0014] In one feasible technical solution of this application, the retractable elastic sealing cover is a transparent polyurethane steel wire corrugated hose.

The exhaust gas pipeline is connected to the bottom of the exhaust pipe, and the exhaust fan and the integrated exhaust gas treatment machine are installed on the exhaust gas pipeline.

[0016] In one feasible technical solution of this application, the lifting mechanism includes two sets of lifting cylinders, the lifting cylinders are arranged vertically, and the bottom of the output shaft of the lifting cylinder is connected to a horizontally arranged flange connecting plate. The flange connecting plate is attached to the upper surface of the upper heating plate and is fixedly connected by bolts.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] When the upper and lower heating plates are undergoing vulcanization, the addition of a retractable elastic sealing cover ensures that all irritating gases generated between them are collected in the sealed chamber. Almost all of the irritating gases then enter the exhaust gas treatment system through the exhaust pipe for processing. This prevents a large amount of irritating gases from entering the production workshop, resulting in more thorough treatment of irritating odors, which is beneficial to the health of workers and more environmentally friendly and safe.
