Description

Technical Field

[0001] This utility model relates to the technical field of quality preservation devices for feed processing, and in particular to a quality preservation device with a scraping function. Background Technology

[0002] Conditioning units are generally used in the conditioning section of feed processing to keep materials warm for extended periods to improve maturation, especially for powdered feeds, as this directly affects the quality of the finished product. Traditional conditioning units use steam jackets for auxiliary heating, which involves numerous piping lines, long preparation times, and low efficiency. Furthermore, their single-cylinder, single-shaft structure results in a low filling coefficient and poor material kneading. The single-side door design also makes cleaning inconvenient. Utility Model Content

[0003] The technical problem to be solved by this utility model is: In order to overcome the above-mentioned technical problems, this utility model provides a quality preservation device with scraping function, which can effectively shorten the preparation time and improve the production efficiency; improve the conditioning time, the kneading effect of the material, improve the gelatinization degree, and facilitate granulation; for materials with high hygiene requirements, the double-sided large opening door can effectively solve the problem of difficult cleaning of dead corners.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a quality retainer with scraping function, comprising a cylinder and a conditioning shaft. The cylinder has an inlet and an outlet. Two conditioning shafts are provided inside the cylinder, arranged side by side in parallel. Each conditioning shaft has helical blades on its outer circumference, and the helical blades of the two conditioning shafts are staggered. The cylinder is a double-cylinder structure that is interconnected. The two cylinders are arranged side by side in parallel, and the two cylinders partially overlap. The two conditioning shafts are located on two circles of the double-cylinder structure. Inside the cylinder, the tempering shaft is coaxial with the cylinder itself. A scraping device is located near the discharge port on the tempering shaft. This scraping device includes multiple scraping blades, each blade comprising a scraping disc and a screw. The screw is fixed to the tempering shaft. One end of the scraping disc is fixed to the screw, and the other end abuts against the side wall of the cylinder. One side of the scraping disc abuts against the bottom surface of the cylinder. The cylinder is cylindrical; the side wall and bottom surface refer to the curved side and circular bottom surface of the cylinder, not their specific positions. The side of the scraping disc abutting against the bottom surface of the cylinder has an inclined surface 's'. The scraping disc and screw are perpendicular to the tempering shaft, and the plane containing the scraping disc is inclined relative to the bottom surface of the cylinder.

[0005] Preferably, the outer edge of the scraper blade that abuts against the side wall of the cylinder is arc-shaped, fitting snugly against the side wall of the cylinder. This arc-shaped outer edge allows for better fit against the arc-shaped side wall of the cylinder.

[0006] Preferably, the angle α between the plane of the scraper and the bottom surface of the cylinder is 45°.

[0007] Preferably, the inclination angle of the inclined surface s relative to the plane where the scraper is located is 30°-50°.

[0008] Preferably, the two conditioning shafts have the same rotation direction and outer diameter. The material conveying direction of the two shafts is the same, ensuring first-in, first-out material flow, and the material will be biased to one side, achieving material extrusion and better gelatinization. Matching the outer diameter of the two shafts with the inner diameter of the cylinder improves the filling coefficient.

[0009] Preferably, the cylinder is provided with an electrically heated heating element, and the electrically heated heating element contains a temperature sensor.

[0010] Preferably, the cylinder is provided with an inspection door, which is located on the side of the cylinder, and the cylinder is provided with an upper gas spring connected to the inspection door.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a quality retainer with a scraping function. The two conditioning shafts rotate in the same direction, ensuring the material is evenly kneaded during its forward movement, resulting in good conditioning effect and gelatinization. The double-cylinder structure, combined with the double conditioning shaft structure, allows the cylinder to match the stirring range of the conditioning shafts as closely as possible, thereby improving the filling coefficient. The scraping device prevents material residue on the cylinder wall. The inclined surface of the scraper blade can achieve surface contact with the bottom surface of the cylinder, improving the cleaning effect. The outer edge of the scraper blade against the side wall of the cylinder is arc-shaped, allowing for better contact with the arc-shaped side wall of the cylinder. The cylinder is insulated with thermal insulation, effectively improving the heating efficiency of the cylinder. A double-opening, large-angle inspection door facilitates cleaning of materials in hard-to-reach areas. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] like Figure 1-2 As shown, this utility model discloses a material-scraping preservative device, comprising a cylinder 1 and conditioning shafts 2. The cylinder 1 has an inlet 1-1 and an outlet 1-2. Two conditioning shafts 2 are arranged parallel to each other inside the cylinder 1, and each shaft 2 has spiral blades 3 on its outer circumference. The spiral blades 3 of the two conditioning shafts 2 are staggered. The cylinder 1 is a double-cylinder structure with interconnected sections. The two cylinders are arranged parallel to each other, with some overlap in space. The two conditioning shafts 2 are located within the two cylinders of the double-cylinder structure, and are coaxial with their respective cylinders. The co-rotation of the two conditioning shafts 2 ensures more uniform mixing of the material during its forward movement, resulting in better conditioning and gelatinization. The double-cylinder structure of this utility model, combined with the double conditioning shafts 2, allows the cylinder 1 to match the mixing range of the conditioning shafts 2 as closely as possible, thereby improving the filling coefficient, resulting in a high filling coefficient.

[0022] A scraping device is provided on the tempering shaft 2 near the discharge port 1-2 to prevent material residue on the cylinder wall. The scraping device includes multiple scraping blades 4, each of which includes a scraping blade 4-1 and a screw 4-2. The screw 4-2 is fixed to the tempering shaft 2 and can be secured to the tempering shaft by a nut. One end of the scraping blade 4-1 is fixed to the screw 4-2, and the other end of the scraping blade 4-1 abuts against the side wall 1-3 of the cylinder 1. The scraping blade 4-1 has one side abutting against the bottom surface 1-4 of the cylinder 1. The cylinder is cylindrical. Here, the side wall 1-3 and bottom surface 1-4 of the cylinder refer to the cylindrical arc-shaped side surface and the circular bottom surface, and are not limited to their specific positions. The scraper blade 4-1 has an inclined surface s on its side abutting the bottom surface 1-4 of the cylinder 1. The scraper blade 4-1 and the screw 4-2 are set perpendicular to the conditioning shaft 2. The plane of the scraper blade 4-1 is inclined relative to the bottom surface 1-4 of the cylinder 1. During installation, the angle between the scraper blade 4-1 and the conditioning shaft 2 can be adjusted so that the plane of the scraper blade 4-1 is inclined relative to the bottom surface 1-4 of the cylinder 1. This allows the inclined surface s of the scraper blade 4-1 to make surface contact with the bottom surface 1-4 of the cylinder 1, improving the cleaning effect.

[0023] like Figure 4-5 As shown, the angle α between the plane of the scraper blade 4-1 and the bottom surface 1-4 of the cylinder 1 is 45°. Combined with the inclination angle of the inclined surface s, this allows the inclined surface s of the scraper blade 4-1 to achieve surface contact with the bottom surface 1-4 of the cylinder 1, improving the cleaning effect. Since the scraper blade 4-1 is generally made of a material with a certain degree of elasticity to better conform to the inner wall for scraping, the inclination angle of the inclined surface s relative to the plane of the scraper blade 4-1 can be selected between 30° and 50°, with the inclination surface s conforming to the bottom surface 1-4 of the cylinder 1. The outer edge of the scraper blade 4-1 that abuts against the side wall 1-3 of the cylinder 1 is arc-shaped, conforming to and abutting against the side wall 1-3 of the cylinder 1. This arc-shaped outer edge allows for better conformation to the arc-shaped side wall 1-3 of the cylinder 1.

[0024] like Figure 3 As shown, the two conditioning shafts 2 have the same rotation direction and outer diameter. The material conveying direction of the two conditioning shafts 2 is the same, ensuring first-in, first-out material flow, and the material tends to be biased to one side, achieving material extrusion and better gelatinization. The outer diameter of the two conditioning shafts 2 matches the inner diameter of the cylinder 1, which improves the filling coefficient.

[0025] The cylinder 1 is insulated with an electric heating element. The electric heating element is equipped with a temperature sensor inside, which can detect temperature changes in real time. When the temperature reaches the set temperature, the electric heating element stops heating. The temperature fluctuation value can be set according to the requirements. When the temperature is lower than the set temperature range, the heating is cyclical to keep the temperature inside the cylinder 1 at the set temperature, maintain the stability of the material temperature inside the cylinder 1, and avoid the generation of condensate.

[0026] The cylinder 1 is equipped with an inspection door 5, which is located on the side of the cylinder 1. An upper gas spring 6 is connected to the inspection door 5, and the upper gas spring 6 can drive the inspection door 5 to open and close, saving manpower. The inspection door 5 opens to the side, which can realize a large-angle opening on both sides for convenient maintenance and cleaning. Figure 6 This is a diagram showing the opening of inspection door 5. A limit switch is located below inspection door 5 to detect its opening and closing status, ensuring safety.

[0027] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
