Multilayer smelting device for flame-retardant materials

Abstract

This utility model application discloses a multi-layer melting device for flame-retardant materials, including a melting tank mounted on a support frame, and a multi-layer melting module fixedly installed inside the melting tank. The multi-layer melting module includes a partition and a multi-layer melting mechanism, with the partition fixedly installed at the lower part of the melting tank. This multi-layer melting device melts the flame-retardant material by placing it in the innermost second heating cylinder of the multi-layer melting mechanism. The heating plates in each second heating cylinder and the first heating cylinder heat the material, causing it to melt from the innermost second heating cylinder. The melted material then flows sequentially into each second heating cylinder and the first heating cylinder through a guide channel, thus enabling multi-layer melting of the flame-retardant material. Finally, the melted flame-retardant material flows into the discharge chamber from the discharge chute at the partition. This device effectively improves the melting efficiency and uniformity of flame-retardant materials, thereby improving the melting quality of the flame-retardant materials.

Description

Technical Field

[0001] This utility model relates to the field of smelting technology, specifically to a multi-layer smelting device for flame-retardant materials. Background Technology

[0002] Flame retardant materials are materials that can inhibit or delay combustion while not easily igniting themselves. They are widely used in clothing, petroleum, chemical, metallurgical, shipbuilding, fire protection, and national defense industries. Flame retardant materials are generally prepared in granular form for storage, transportation, and subsequent smelting. However, due to their inherent flame-retardant properties, the smelting of existing flame retardant materials is difficult, requiring high melting temperatures, long melting times, and uneven melting results. Existing smelting equipment cannot perform rapid, efficient, and high-quality smelting of flame retardant materials, failing to meet user needs. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: A multi-layer melting device for flame-retardant materials includes a melting tank, which is fixedly installed on a support frame, and a multi-layer melting module, which is fixedly installed inside the melting tank. The multi-layer melting module includes a partition and a multi-layer melting mechanism. The partition is fixedly installed at the lower part of the melting tank, and a discharge cavity is formed between the partition and the inner bottom wall of the melting tank. Several discharge slots are evenly opened at the edge of the partition. The multi-layer melting mechanism is fixedly installed on the partition and includes a first heating cylinder and several second heating cylinders. The first heating cylinder and each second heating cylinder are fixedly installed on the partition. Each second heating cylinder is nested in sequence and is located inside the first heating cylinder.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1 to 2 The present invention provides the following technical solution: A flame-retardant material multi-layer melting device includes a melting tank, which is fixedly installed on a support frame 16. The support frame 16 is used to elevate the melting tank. The device also includes a multi-layer melting module, which is fixedly installed inside the melting tank. The multi-layer melting module can melt the flame-retardant material in multiple layers, thereby improving the melting quality of the material. The multi-layer melting module includes a partition plate 8 and a multi-layer melting mechanism. The partition plate 8 is fixedly installed at the lower part of the melting tank and is used to install the multi-layer melting mechanism. The multi-layer melting mechanism is fixedly installed on the partition plate 8. A discharge chamber 14 is formed between the partition plate 8 and the inner bottom wall of the melting tank. Several discharge grooves 9 are evenly opened at the edge of the partition plate 8. The material melted by the multi-layer melting mechanism flows from the discharge grooves 9 into the discharge chamber 14. The multi-layer melting mechanism includes a first heating cylinder 10 and several second heating cylinders 11. The first heating cylinder 10 and each of the second heating cylinders 11 are fixedly installed on the partition plate 8. The second heating cylinders 11 are nested in sequence, with the second heating cylinders 11 located inside the first heating cylinder 10. The first heating cylinder 10 and the second heating cylinders 11 are separate. The second heating cylinders 11 are separated from each other, and each second heating cylinder 11 is coaxially arranged with the first heating cylinder 10. A corresponding material cavity is formed between each second heating cylinder 11 and the first heating cylinder 10. The flame retardant material is initially placed in the innermost second heating cylinder 11. Several electric heating rods 12 are installed in the second heating cylinder 11 inside the first heating cylinder 10. The electric heating rods 12 can heat the first heating cylinder 10 and the second heating cylinder 11. Several guide ports 13 are evenly opened on the side wall of the second heating cylinder 11, so that the flame retardant material can flow out from the innermost second heating cylinder 11 through the guide ports 13 to the outermost second heating point, until it flows into the first heating cylinder 10, and finally flows into the discharge chamber 14 from the discharge chute 9 at the partition 8.

[0014] The melting tank includes a cover 1 and a tank body 6. The cover 1 is installed at the open end of the tank body 6. The tank body 6 and the cover 1 form a closed structure. A feeding port 2 is provided in the middle of the cover 1. The feeding port 2 is adapted to the innermost second heating cylinder 11 of the multi-layer melting module and is used to feed the flame-retardant material to be melted into the innermost second heating cylinder 11.

[0015] The cover 1 is equipped with a pressure gauge 3, a high-pressure connector 4, and a pressure relief valve 5. The pressure gauge 3 is used to detect the pressure inside the melting tank. The high-pressure connector 4 is used to connect the high-pressure melting gas, which can input the corresponding gas into the melting tank to increase the pressure inside the melting tank and further improve the melting efficiency of the material. The pressure relief valve 5 is used to relieve excessive pressure inside the melting tank.

[0016] The bottom of the tank body 6 is provided with a discharge port 15, which is connected to the discharge chamber 14. A corresponding valve is installed in the discharge port 15 to discharge the smelted flame-retardant material.

[0017] The outer side of the can 6 is wrapped with a heat insulation layer 7, which reduces the heat loss of the can 6 and prevents users from being burned by accidentally touching the can 6.

[0018] The specific implementation process is as follows: When using this multi-layer melting device for flame-retardant materials, firstly, feed the material into the innermost second heating cylinder 11 of the multi-layer melting mechanism through the feeding port 2. Then, close the melting tank to make it sealed. The corresponding high-pressure melting gas can be connected at the high-pressure connector 4 as needed. Then, start the electric heating rod 12 in the first heating cylinder 10 and the second heating cylinder 11. The electric heating rod 12 heats the first heating cylinder 10 and the second heating cylinder 11, and the first heating cylinder 10 and the second heating cylinder 11 can melt the flame-retardant material inside. The second heating cylinder 11 containing the flame-retardant material melts the flame-retardant material. The molten flame-retardant material flows from the guide port 13 on the side of the second heating cylinder 11 into a more outer second heating cylinder 11, until it flows through each second heating cylinder 11 into the first heating cylinder 10. The flame-retardant material is melted through the multi-layer heating of each second heating cylinder 11 and the first heating cylinder 10, and finally flows into the discharge chamber 14 from the discharge chute 9 at the edge of the partition 8, thus completing the melting of the flame-retardant material.

[0019] This multi-layer melting device for flame-retardant materials places the flame-retardant material in the innermost second heating cylinder 11 of the multi-layer melting mechanism. The heating plates in each second heating cylinder 11 and the first heating cylinder 10 heat up to melt the material, so that the material is melted from the innermost second heating cylinder 11 and flows into each second heating cylinder 11 and the first heating cylinder 10 in sequence through the guide channel. This allows the device to perform multi-layer melting of the flame-retardant material. Finally, the melted flame-retardant material flows into the discharge chamber 14 from the discharge chute 9 at the partition 8. This device can effectively improve the melting efficiency and melting uniformity of the flame-retardant material, thereby improving the melting quality of the flame-retardant material.
