Description

Technical Field

[0001] This utility model relates to the field of corrugated pulp production technology, specifically to a mixer for corrugated pulp production. Background Technology

[0002] Corrugated pulp refers to the pulp used to produce corrugated board and corrugated paper. It is typically made from recycled waste paper or virgin wood pulp through processes such as pulping, screening, washing, deinking, and concentration. Its main characteristics are long fibers, high strength, and strong plasticity, providing excellent cushioning and compressive strength to meet the requirements of corrugated board for stiffness, bursting strength, and compressive strength. Based on production processes and raw material sources, corrugated pulp can be classified into waste paper pulp, chemical pulp, and mechanical pulp, and is widely used in packaging, transportation, and industrial manufacturing.

[0003] Chinese patent CN215877725U discloses a pulp mixing device for corrugated paper production. The device includes a pulp mixer, hinges, and a cover plate. The cover plate is located at the top of the pulp mixer, and the hinges are located behind the pulp mixer and the cover plate.

The sealing mechanism 2 is provided on one side of the surface of the tank 1, and the stirring mechanism 3 is provided at one end of the tank 1.

[0028] The sealing mechanism 2 includes a feed inlet 201, a threaded groove 202, a sealing ring 203, a cover plate 204, a threaded water inlet groove 205, a water inlet pipe 206, and a sealing cover 207. A feed inlet 201 is provided on one side of the surface of the tank body 1. A threaded groove 202 is also provided on one side of the surface of the tank body 1. A sealing ring 203 is installed at the inner edge of the feed inlet 201. A cover plate 204 is fitted onto the surface of the feed inlet 201. A threaded water inlet groove 205 is provided on one side of the surface of the cover plate 204. A water inlet pipe 206 is threadedly connected to the inside of the threaded water inlet groove 205. A sealing cover 207 is also threadedly connected to the inside of the threaded water inlet groove 205. Through the arrangement of the feed inlet 201, threaded groove 202, sealing ring 203, cover plate 204, threaded water inlet groove 205, water inlet pipe 206, and sealing cover 207, material passes through the feed inlet 201. The feed inlet 201 is fitted with a sealing ring 203 on its inner edge to ensure a tight seal during feeding. The cover plate 204 is fitted onto the feed inlet 201 and threaded onto the tank 1 via the threaded groove 202 to ensure a secure seal. The threaded water inlet groove 205 is threaded with a water inlet pipe 206 for adding liquid into the tank 1. The sealing cap 207 is used to seal the water inlet pipe 206 to prevent external contamination or liquid leakage.

[0029] Furthermore, two sets of sealing caps 207 are provided, and sealing rings 203 are also installed at the outer edge of the tank body 1.

[0030] The other side of 203 is tightly fitted to the cover plate 204. With the setting of the sealing ring 203, when the cover plate 204 is fitted on the feed port 201, the sealing ring 203 can prevent internal material leakage, prevent dust or liquid seepage, avoid external impurities from entering the tank 1, and ensure the sealing of the internal environment.

[0031] Furthermore, one side of the cover plate 204 is threaded into the inside of the threaded groove 202, which is located on the outside of the feed inlet 201. Through the setting of the threaded groove 202, one side of the cover plate 204 is embedded into the threaded groove 202 by threaded connection, so that it is firmly installed in the feed inlet 201 of the tank body 1. This threaded installation method avoids the loosening or non-sealing problems that may be caused by welding or snap-fit ​​connection.

[0032] Furthermore, two sets of threaded water inlet grooves 205 are provided, symmetrically distributed on the cover plate 204. Through the threaded water inlet grooves 205, the water inlet pipe 206 is screwed into the grooves, ensuring its stability and preventing loosening or leakage during water intake. This also facilitates the disassembly and replacement of water inlet pipes 206 of different specifications, improving equipment compatibility.

[0033] When water is not required, the sealing cap 207 can be screwed into the threaded water inlet groove 205 to completely seal the water inlet and prevent dust or air from entering the tank 1.

[0034] Furthermore, the stirring mechanism 3 includes a fixed frame 301, a support plate 302, a mounting groove 303, a discharge hopper 304, a motor 305, a one-way valve 306, a connecting hopper 307, a rotating rod 308, a connecting pipe 309, a stirring fan assembly 310, and a scraper assembly 311. The fixed frame 301 is connected to the inner wall of the tank body 1, and the support plate 302 is connected to the flange on the other side of the tank body 1. The mounting groove 303 is opened inside the fixed frame 301. The discharge hopper 304 is fixedly connected to one side of the support plate 302. The interior of the mounting groove 303 is fitted with the output end of the motor 305. The one-way valve 306 is installed on one side of the surface of the discharge hopper 304, and the connecting hopper 307 is connected to the other side of the discharge hopper 304. The rotating rod 308 is connected to the output end of the motor 305. One end of the connecting hopper 307 is threadedly connected to a connecting pipe 309. A stirring fan assembly 310 is connected to the surface of the rotating rod 308, and a scraper assembly 311 is also connected to the surface of the rotating rod 308. Through the arrangement of the fixing frame 301, support plate 302, mounting groove 303, discharge hopper 304, motor 305, one-way valve 306, connecting hopper 307, rotating rod 308, connecting pipe 309, stirring fan assembly 310, and scraper assembly 311, when material is added to tank 1, the motor 305 is started. The drive rod 308 rotates, causing the stirring fan assembly 310 and scraper assembly 311 to move. There are four sets of stirring fan assemblies 310, which are evenly distributed inside the scraper assembly 311. During rotation, they can effectively stir the material in the tank 1, making it fully mixed. The scraper assembly 311 is close to the inner wall of the tank 1. During rotation, it can scrape off the material adhering to the tank wall, avoiding residue and improving stirring efficiency. After stirring, the material is discharged through the discharge hopper 304. A one-way valve 306 is installed at the outlet of the discharge hopper 304 to prevent material backflow and ensure smooth discharge. The material flows out through the connecting hopper 307 and the connecting pipe 309 for subsequent processing or collection.

[0035] Furthermore, the two sides of the rotating rod 308 are set in the fixed frame 301. The rotating rod 308 and the fixed frame 301 form a mutual sliding structure through the motor 305. The fixed frame 301 plays a guiding role to ensure that the rotating rod 308 keeps its axis stable during rotation and does not deviate or wobble. In cooperation with the motor 305, the rotating rod 308 and the fixed frame 301 form a mutual sliding structure, reducing friction, improving stirring efficiency, and thus preventing the rotating rod 308 from deviating due to uneven force, thereby improving the accuracy of the stirring motion.

[0036] Furthermore, the main body of the motor 305 is supported in the fixed frame 301, and the main body of the motor 305 is set in the central area of ​​the tank 1. The main body of the motor 305 runs through the tank 1. Through the setting of the motor 305, the motor 305 drives the rotating rod 308 to rotate, thereby driving the stirring fan assembly 310 and the scraper assembly 311 to rotate, so as to achieve full mixing of materials. Through the continuous operation of the motor 305, the materials can be evenly mixed, avoiding sedimentation or agglomeration, and improving the mixing quality.

[0037] Furthermore, two sets of scraper groups 311 are provided, which are evenly distributed on the rotating rod 308. The other side of the scraper group 311 is in contact with the inner wall of the tank 1. Through the arrangement of the scraper group 311, during the stirring process, the scraper group 311 rotates with the rotating rod 308 to scrape the inner wall of the tank 1, preventing the material from adhering to the tank wall, effectively reducing scale and residue on the tank wall, and keeping the tank 1 clean.

[0038] Furthermore, four sets of stirring fan assemblies 310 are provided. These assemblies are located inside the scraper assembly 311. The stirring fan assemblies 310 rotate with the rotating rod 308, creating a strong stirring flow field that ensures uniform material flow within the tank 1. The four sets of stirring fan assemblies 310 are evenly spaced, covering the entire interior of the tank 1 for more uniform mixing.

[0039] It prevents incomplete mixing in certain areas and is particularly suitable for mixing liquids, suspensions, or slurries, ensuring uniform distribution of different components and improving product quality.

[0040] In this embodiment, during use, the material enters the tank 1 through the feed inlet 201. A sealing ring 203 is installed on the inner edge of the feed inlet 201 to ensure sealing during feeding. The cover plate 204 is fitted onto the feed inlet 201 and threadedly connected to the tank 1 through the threaded groove 202 to ensure a stable seal. A water inlet pipe 206 is threadedly connected to the threaded water inlet groove 205 for adding liquid into the tank 1. The sealing cover 207 is used to seal the water inlet pipe 206 to prevent external contamination or liquid leakage. When the material is added to the tank 1, the motor 305 is started. The motor 305 drives the rotating rod 308 to rotate, which drives the stirring fan assembly 310 and the scraper assembly 311 to move. There are four stirring fan assemblies 310, which are evenly distributed inside the scraper assembly 311. During rotation, they can effectively stir the material in the tank 1 to ensure thorough mixing. The scraper assembly 311... Closely attached to the inner wall of tank 1, it can scrape off the material adhering to the tank wall during rotation, avoiding residue and improving stirring efficiency. After stirring, the material is discharged through discharge hopper 304. A one-way valve 306 is installed at the outlet of discharge hopper 304 to prevent material backflow and ensure smooth discharge. The material flows out through connecting hopper 307 and connecting pipe 309 for subsequent processing or collection.
