Description

Technical Field

[0001] The utility model belongs to the technical field of synthetic resin processing, and relates to a melting furnace device for synthetic resin processing, in particular to a raw material melting furnace device for synthetic resin processing. Background Art

[0002] Synthetic resin is a kind of artificially synthesized high molecular polymer. It is a macromolecular material formed by combining low molecular raw materials such as monomers such as ethylene, propylene, vinyl chloride, etc. through a series of polymerization reactions. It is a viscous liquid or a solid that can be softened by heating. It usually has a melting or softening temperature range when heated. It can be in a plastic flow state under the action of external force. Some properties are similar to those of natural resins. The raw materials for the production of synthetic resins are abundant. In the early days, coal tar products and calcium carbide were the main ones. Now, they are mainly petroleum and natural gas products, such as ethylene, propylene, benzene, formaldehyde and urea.

[0003] After searching, a smelting device for synthetic resin production disclosed in Chinese patent literature [Application number: CN202121848940.8; Announcement number: CN216068190U], this smelting device for synthetic resin production includes: a smelting furnace body and a cover plate; a wall scraper assembly, the wall scraper assembly is arranged inside the smelting furnace body, and is used to scrape and clean the smelting residues on the inner wall of the smelting furnace body, wherein the wall scraper assembly includes: a wall scraper drive assembly, which is used to drive the wall scraper assembly to rotate to perform wall scraping work; a wall scraper adjustment assembly, which is connected to the wall scraper drive assembly to adjust the distance between the wall scraper assembly and the wall body; a wall scraper range adjustment assembly, which is connected to the wall scraper adjustment assembly to adjust the position of the wall scraper.

[0004] Although the smelting device disclosed in the patent can scrape off the deposits on the inner wall of the smelting furnace through the scraping assembly, the scraping assembly of the current smelting device can only scrape the inner wall of the furnace body locally by moving up and down and rotating, and the cleaning range is limited. In addition, the diameter position of the blade is adjusted by the screw, which causes the up and down position of the blade to change, and it is impossible to achieve accurate and large-scale cleaning and scraping of the inner wall of the furnace body. Utility Model Content

[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and to propose a raw material melting furnace device for synthetic resin processing. The technical problem to be solved by the utility model is: how to achieve accurate and large-scale scraping and cleaning of residues on the inner wall of the furnace body.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A raw material melting furnace device for synthetic resin processing, comprising a furnace body, a feed port fixedly installed at the top of the furnace body, a discharge port fixedly installed at the bottom of the furnace body and a bracket connected to the bottom of the furnace body, a fixed column fixedly connected to the inside of the furnace body, the axis of the fixed column coincides with the axis of the furnace body, the upper and lower outer walls of the fixed column are rotatably connected to a turntable, a plurality of rotating grooves are annularly opened inside the turntable, the inner wall of the rotating groove is slidably connected to a sliding column, and the outer wall of the sliding column is fixedly connected to a connecting plate;

[0010] With the above structure, under the meshing action of the gear ring and the gear plate, the gear ring drives the turntable to rotate, and the two turntables are rotated synchronously by fixing the connecting rod between the two turntables. At the same time, under the action of the rotating groove provided inside the turntable, when the turntable rotates, the connecting plate is extended through the sliding column in the rotating groove, so that the connecting plate drives the cleaning blade at the outer end to fit the inner wall of the furnace body, and the inner extension rod and the fixed rod are connected by the inner wall of the cleaning blade to limit the extension path of the connecting plate, thereby ensuring the extension effect of the cleaning blade, and under the continued rotation of the turntable, the turntable is The over-slip column drives the connecting plate to rotate, which in turn drives the outer cleaning blade to rotate, and the rotation connection with the fixed column through the sleeve ring makes multiple cleaning blades rotate stably on the outer wall of the fixed column, thereby realizing efficient cleaning of the inner wall of the furnace body. When the device is in normal melting furnace, by driving the gear plate to rotate in the opposite direction, the meshing action of the gear ring and the gear plate makes the turntable drive the outer cleaning blade to shrink through the rotating groove, thus avoiding the scratching of the cleaning blade and the inner wall of the furnace body, making it convenient for the cleaning blade and the connecting plate to rotate as a whole inside the furnace body, which is beneficial to improving the melting uniformity of the synthetic resin inside the furnace body.

[0016] By adopting the above structure, through the meshing setting of the gear plate and the gear ring, under the driving action of the driving motor, the gear plate can drive the gear ring to rotate on the outer wall of the fixed column, so that the turntable drives the rotating groove to rotate on the outer wall of the fixed column, so that the rotating groove drives the connecting plate to extend and retract through the sliding column, so that the user can adjust the extension and retraction of the peripheral cleaning blade by the rotation of the gear ring.

[0017] The outer wall of the fixed column is rotatably connected to a ring, the ring is located between the two turntables, the outer wall of the ring is fixedly connected to a plurality of fixed rods, the plurality of fixed rods are equidistantly distributed in a ring, and the interior of the fixed rod is slidably and telescopically connected to an inner extension rod, and one end of the inner extension rod away from the fixed rod is fixedly connected to the inner wall of the cleaning blade.

[0018] By adopting the above structure, through the rotational connection between the sleeve and the fixed column, when the turntable is subsequently rotated through the gear ring, after the turntable extends the connecting plate through the rotating groove, the connecting plate drives the cleaning blade to fit and scrape the inner wall of the furnace body, so that when the turntable continues to rotate, the turntable as a whole rotates on the outer wall of the fixed column, and the cleaning blade rotates synchronously on the outer wall of the fixed column through the inner extension rod, the fixed rod and the sleeve in the middle, so that the cleaning blade rotates on the inner wall of the furnace body to clean the residue on the inner wall of the furnace body.

[0019] The interior of the fixed rod is fixedly connected with a telescopic spring, and the other end of the telescopic spring is fixedly connected with an inner extension rod, and the inner extension rod is arranged in parallel with the connecting plate.

[0020] With the above structure, under the sliding action of the inner extension rod and the fixed rod, through the fixed connection between the inner extension rod and the cleaning blade, the inner extension rod can limit the movement of the connecting plate inside the rotating groove through the sliding column, thereby realizing the stable extension and retraction of the cleaning blade inside the furnace body.
