Description

Technical Field

[0001] The utility model relates to the technical field of bio-based polyester polyol compound synthesis, in particular to a bio-based polyester polyol compound synthesis device. Background Art

[0002] Bio-based polyester polyol compounds are usually hydroxyl-terminated polyesters formed by esterification and polycondensation of polyols and organic dicarboxylic acids (anhydrides) or polymerization of polyols and lactones. The average molecular weight is 1000-4000, and the carboxyl concentration does not exceed 0.02 mol kg. Polyester polyols are mainly used as raw materials for polyurethane synthesis. Compared with polyether polyols, they have better wear resistance, oil resistance and temperature resistance, and high mechanical strength. According to the different dicarboxylic acids used, they can usually be divided into aliphatic polyester polyols, aromatic polyester polyols and mixed acid polyester polyols. Aromatic polyester polyols introduce benzene ring structures into their molecular structures, which increases the benzene ring content in the polyurethane chain, and thus make the rigid polyurethane foam prepared from them have the advantages of low brittleness, good toughness, high strength, low thermal conductivity, good flame retardancy and low price. They are widely used in the fields of insulation, shockproof, sound insulation and packaging materials.

[0003] After searching, in the prior art, a Chinese patent with patent application number CN 214973930 U discloses a synthesis device for bio-based polyester polyol compounds, including a device body, the device body including a shell, a rotating motor is installed on the top of the shell, and the output end of the rotating motor extends to the inside of the shell, a rotating rod is installed inside the shell, and the rotating rod is connected to the output end of the rotating motor extending to the inside of the shell, and a sleeve ring is sleeved and installed on the outer surface of the rotating rod, and the number of the sleeve rings is two, but there are still the following defects:

[0004] (1) In the above patent document, a bonding plate is used to stir the compound. However, due to the large gap between the bonding plate and the bottom of the shell, and the bonding plate cannot move up and down in the shell, the bonding plate cannot fully stir the compound at the bottom of the shell, thereby reducing the production efficiency and production quality of the compound;

[0005] (2) In the above patent document, when the processed compound is unloaded, the compound is discharged from the discharge port only by gravity. Although the discharge port is unblocked by a stirring screw, the outflow speed of the compound with higher viscosity is still relatively slow, which reduces the unloading efficiency of the compound.

[0006] Therefore, we have made improvements on this and proposed a synthesis device for bio-based polyester polyol compounds. Utility Model Content

[0007] The purpose of the utility model is to address the existing use of a bonding plate to stir the compound. Since there is a large gap between the bonding plate and the bottom of the shell, and the bonding plate cannot move up and down in the shell, the bonding plate cannot fully stir the compound at the bottom of the shell, which reduces the production efficiency and production quality of the compound. When the processed compound is unloaded, the compound is discharged from the discharge port only by gravity. Although the discharge port is unblocked by a stirring screw, the outflow speed of the compound with a higher viscosity is still relatively slow, which reduces the unloading efficiency of the compound.

[0012] A discharge assembly, fixedly connected to the bottom wall of the housing, for unloading the processed compound;

[0013] A dredging component, fixedly connected to the bottom wall of the shell, used for dredging the discharge component;

[0014] The feed assembly is fixedly connected to the top wall of the shell and is used for feeding compound raw materials.

[0016] As a preferred technical solution of the utility model, the unloading assembly includes a unloading pipe fixedly connected to the bottom wall of the shell, and the unloading pipe is communicated with the shell.

[0017] As a preferred technical solution of the utility model, the dredging assembly includes a mounting frame fixedly connected to the bottom wall of the shell, a hydraulic cylinder fixedly connected to the bottom wall of the mounting frame, and a sealing head fixedly connected to the telescopic end of the hydraulic cylinder, and the sealing head is tightly fitted to the inner wall of the discharge pipe and is slidably connected.

[0018] As a preferred technical solution of the present utility model, the feed assembly includes a feed pipe fixedly connected to the top wall of the shell, and the feed pipe is communicated with the interior of the shell.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] In the solution of the utility model:

[0021] 1. The stirring column is driven by a stirring motor to drive the stirring plate to rotate, and the cleaning motor drives the spiral scraper to rotate by driving the transmission frame. Since the spiral scraper is closely attached to the inner wall of the shell, the compound in the shell is turned upside down, so that the raw materials of the compound are fully stirred, which solves the problem of using a bonding plate to stir the compound in the prior art. Since there is a large gap between the bonding plate and the bottom of the shell, and the bonding plate cannot move up and down in the shell, the bonding plate cannot fully stir the compound at the bottom of the shell, which reduces the production efficiency and production quality of the compound;

[0022] 2. The cleaning motor is set to drive the spiral scraper to rotate in the opposite direction, and the spiral scraper scrapes the compound attached to the inner wall of the shell off the shell and actively transfers it downward. When the compound is transferred to the bottom of the shell, the spiral scraper drives the compound into the discharge pipe, thereby realizing active cleaning and rapid unloading of the compound. This solves the problem in the prior art that when the processed compound is unloaded, the compound is discharged from the discharge port only by gravity. Although the discharge port is unblocked by a stirring screw, the outflow speed of the compound with higher viscosity is still relatively slow, which reduces the unloading efficiency of the compound.
