Description

Technical Field

[0001] This application relates to the field of hot plate insulation technology, and more specifically, to an electromagnetic heating insulation ring for a capsule vulcanizing machine applied to a circular hot plate. Background Technology

[0002] The electromagnetic heating insulation ring of the capsule vulcanizing machine is suitable for circular hot plates. With the electromagnetic heating system, the electromagnetic coil generates oscillating eddy currents through frequency conversion technology, which heats up the hot plate. It is used by companies that produce rubber products such as rubber tires, seals, and miscellaneous rubber parts using capsule vulcanizing machines.

[0003] The following drawbacks exist in traditional electromagnetic heating processes:

[0004] 1. Low thermal efficiency: Traditional resistance wire heating suffers from high thermal inertia and slow response, and significant radial heat loss (heat loss > 30%). The heating method is outdated, and the resistance wire winding heating coil heats up slowly (> 10 minutes), resulting in high energy consumption.

[0005] 2. Poor temperature uniformity: The temperature difference between the edge and center of the hot plate often exceeds ±15℃, resulting in uneven vulcanization of the capsule;

[0006] 3. Risk of thermal insulation failure: Conventional ceramic fiber thermal insulation layers are prone to pulverization when used for a long time above 500℃, and may generate eddy current heating under electromagnetic fields. In addition, the thermal insulation performance of single-layer thermal insulation degrades quickly and has a short lifespan in electromagnetic environments.

[0007] 4. High maintenance costs: The entire insulation jacket needs to be replaced when it is damaged. Even if there is partial damage, the entire insulation jacket needs to be disassembled. Replacement takes ≥8 hours. The downtime for maintenance is long. The integral metal bracket is prone to deformation due to heat, which can squeeze the coil and cause a short circuit.

[0008] In view of this, we propose an electromagnetic heating type heat preservation ring for a capsule vulcanizing machine with a circular hot plate. Utility Model Content

[0009] The purpose of this application is to provide an electromagnetic heating insulation ring for a capsule vulcanizing machine with a circular hot plate, which can effectively solve the problems of low thermal efficiency, poor temperature uniformity, risk of insulation failure, and high maintenance costs in the prior art.

[0010] This application provides an electromagnetic heating insulation ring for a capsule vulcanizing machine with a circular hot plate, comprising two end plates. An inner insert plate is arranged in a ring array between the two end plates on the side closer to the hot plate, and an outer insert plate is arranged in a ring array between the two end plates on the side away from the inner insert plate. Nickel-plated electromagnetic wires are wound around the outer side of the inner insert plate, and an inorganic heat insulation plate is arranged in a ring array on the side of the inner insert plate away from the nickel-plated electromagnetic wires.

[0011] As an optional solution to the technical solution of this application, the end plate has a mortise corresponding to the inner insert plate, and the top and bottom of the inner insert plate are fixedly provided with tenons, and the mortise and tenon are connected by a tenon joint.

[0012] As an optional solution to the technical solution of this application, the outer side of the end plate is provided with a mounting groove corresponding to the outer insert plate, and the top and bottom of the outer insert plate are fixedly provided with extension plates, which are fixedly set with the corresponding mounting groove by countersunk screws.

[0013] As an optional solution to the technical solution in this application, the inner annular array of the nickel-plated electromagnetic wire and the inorganic heat insulation board is provided with aerogel sheets, which are used to cooperate with the inorganic heat insulation board to achieve directional thermal barrier.

[0014] As an optional solution to the technical solution in this application, the end plate is made of resin to prevent the outer side from getting too hot.

[0015] As an optional solution to the technical solution of this application, the end plate has a rod hole inside, and a rod is provided on the inner side of the rod hole for connecting to the hot plate.

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0017] (1) This application uses nickel-plated electromagnetic wire, which is resistant to high temperature. The nickel-plated electromagnetic wire is tightly wound on the outside of the inner plate with a turn spacing of ≤1mm, directly forming a heating induction ring. This effectively solves the problems of large thermal inertia and slow response of traditional resistance wire heating, as well as serious radial heat loss, backward heating method, slow temperature rise of resistance wire winding heating coil, high energy consumption, large temperature difference between the edge and center of the hot plate, and uneven sulphurization of capsule.

[0018] (2) This application sets an inorganic heat insulation board on the side of the inner insert plate close to the hot plate, so that the inorganic heat insulation board is spliced ​​into a ring and attached to the hot plate. It is resistant to 500℃ and has electromagnetic inertness. This solves the problems that conventional ceramic fiber heat insulation layers are easy to pulverize after long-term use above 500℃, may generate eddy current heating under electromagnetic field, and the heat insulation performance of single-layer heat insulation decays quickly and has a short lifespan under electromagnetic environment.

[0019] (3) This application uses tenons and mortises to install the inner insert plate, so that the inner insert plate is assembled into a ring. The outer insert plate is installed and fixed by countersunk screws, which plays a protective and support role. This solves the problem that the entire insulation sleeve needs to be replaced after it is damaged, and even if it is partially damaged, the entire insulation sleeve needs to be disassembled. The replacement time is long and the maintenance downtime is long.

[0020] (4) This application solves the problem in the prior art that the integral metal bracket is prone to deformation when heated, which can easily squeeze the coil and cause a short circuit by setting up a double-layer heat insulation of resin end plate, inorganic heat insulation plate and aerogel sheet.

[0021] (5) This application adopts a directional thermal barrier sequence of “aerogel layer (on the side of the hot plate) → inorganic heat insulation plate layer (on the side of the electromagnetic wire)”. By setting a double-layer non-metallic heat insulation barrier between all metal parts and the hot plate, electromagnetic coupling is blocked. By setting an inorganic heat insulation plate, eddy current heating is eliminated, and the working stability of the electromagnetic coil is improved. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-4This application discloses an electromagnetic heating insulation ring for a capsule vulcanizing machine with a circular hot plate. It includes two end plates 1. An inner insert plate 2 is arranged in a ring array on the side of the two end plates 1 closest to the hot plate, and an outer insert plate 3 is arranged in a ring array on the side of the two end plates 1 furthest from the inner insert plate 2. Nickel-plated electromagnetic wires 4 are wound around the outer side of the inner insert plate 2. An inorganic heat insulation plate 5 is arranged in a ring array on the side of the inner insert plate 2 furthest from the nickel-plated electromagnetic wires 4. Aerogel sheets 6 are arranged in a ring array inside the nickel-plated electromagnetic wires 4 and the inorganic heat insulation plate 5 to cooperate with the inorganic heat insulation plate 5 for directional thermal insulation. The end plates 1 are made of resin to prevent excessively high temperatures on the outer side. A hanging rod hole 13 is opened inside the end plate 1, and a hanging rod 7 is arranged inside the hanging rod hole 13 for connecting to the hot plate.

[0029] The insulation ring is connected to the hot plate by the hanging rod 7, so that the inorganic heat insulation board 5 is attached to the hot plate. The double-layer heat insulation, which is achieved by the resin end plate 1, inorganic heat insulation board 5, and aerogel sheet 6, controls the temperature on the outside of the insulation ring to <80℃. This solves the problem in the prior art where the integral metal bracket is easily deformed by heat and squeezes the coil, causing a short circuit.

[0030] By setting up nickel-plated electromagnetic wire 4, the nickel-plated electromagnetic wire 4 is tightly wound around the outside of the inner insert plate 2 to form a heating induction ring, which effectively solves the problems of large thermal inertia and slow response of traditional resistance wire heating, as well as serious radial heat loss, outdated heating method, slow temperature rise of resistance wire winding heating coil, high energy consumption, large temperature difference between the edge and center of the hot plate, resulting in uneven capsule vulcanization.

[0031] By setting up inorganic heat insulation board 5, the inorganic heat insulation board 5 is spliced ​​into a ring and attached to the heat plate. It can withstand a temperature of 500℃ and has electromagnetic inertness. This solves the problems of conventional ceramic fiber heat insulation layer being prone to pulverization when used for a long time above 500℃, and possibly generating eddy current heating under electromagnetic field. It also solves the problems of single-layer heat insulation having rapid heat insulation performance decay and short lifespan under electromagnetic environment.

[0032] By forming a directional thermal barrier sequence through inorganic heat insulation board 5 and aerogel sheet 6, and by setting a double-layer non-metallic heat insulation barrier composed of inorganic heat insulation board 5 and aerogel sheet 6 between all metal parts and the hot plate, electromagnetic coupling is blocked. By setting inorganic heat insulation board 5, eddy current heating is eliminated, and the working stability of nickel-plated electromagnetic wire 4 is improved.

[0033] Reference Figure 2 , Figure 3 and Figure 4 The end plate 1 has a mortise 11 inside corresponding to the inner insert plate 2. The top and bottom of the inner insert plate 2 are fixedly provided with tenons 21. The mortise 11 and the tenon 21 are connected by mortise and tenon joints. The outer side of the end plate 1 has a mounting groove 12 corresponding to the outer insert plate 3. The top and bottom of the outer insert plate 3 are fixedly provided with extension plates 31. The extension plates 31 are fixedly provided with the corresponding mounting grooves 12 by countersunk screws 311.

[0034] The inner insert plate 2 is installed by using the tenon 21 and mortise 11 to assemble the inner insert plate 2 into a ring. The outer insert plate 3 is installed and fixed inside the mounting groove 12 by the countersunk screw 311, which plays a protective and support role. This solves the problem that the entire insulation sleeve needs to be replaced after it is damaged, and even if there is partial damage, the entire insulation sleeve needs to be disassembled, which is time-consuming and causes long downtime for maintenance.

[0035] In summary, the electromagnetic heating insulation ring for a capsule vulcanizing machine with a circular hot plate disclosed in this application is used by connecting the insulation ring to the hot plate via a hanger 7. The inner insert plate 2 is installed by using tenons 21 and mortises 11 to assemble the inner insert plate 2 into a ring. The outer insert plate 3 is installed and fixed inside the mounting groove 12 by countersunk screws 311, which provides protection and support. The nickel-plated electromagnetic wire 4 is tightly wound around the outside of the inner insert plate 2 to form a heating induction ring. The inorganic heat insulation plate 5 is spliced ​​into a ring and attached to the hot plate. The inorganic heat insulation plate 5 and the aerogel sheet 6 form a directional heat barrier sequence.
