Description

Technical Field

[0001] This utility model relates to the field of household paper recycling technology, and in particular to a recycling device for high-moisture-strength damaged household paper. Background Technology

[0002] Wet-strength paper is a special type of paper that retains a certain strength after being exposed to moisture or soaked in water by adding a wet-strength agent during the papermaking process. The waste paper generated during the production process is high-wet-strength waste paper.

[0003] In existing technologies, the recycling of high wet strength paper usually requires a combination of methods to break the network structure formed by wet strength agents and redisperse the fibers. Especially during the thermal decomposition process, high wet strength paper is sent to a pulping and recycling device and mixed with hot water and chemical additives at a certain temperature. Under heating and stirring, the chemical additives can effectively separate the fibers from the wet strength resin.

[0004] Specifically, during the thermochemical decomposition process, high wet strength paper is fed into a pulping device and mixed with heated hot water and chemical additives. At a certain temperature, through stirring, the chemical additives effectively decompose the paper fibers and wet strength resin.

[0005] However, some traditional recycling devices still rely solely on mechanical stirring. Although they can complete basic shredding and separation operations, their processing efficiency is low, making it difficult to completely separate highly wet and damaged paper, and thus the recycling quality and efficiency cannot be guaranteed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a recycling device for high-moisture-strength damaged household paper.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A recycling device for high-wet-strength waste paper for household use includes a machine body. A processing chamber is provided on one side of the machine body. The bottom outlet of the processing chamber is connected to the upper input port of the conveying coil. An output pipe is connected to one side of the bottom of the conveying coil and is connected to the pulp tank inside the machine body. An air jet mechanism is connected to the bottom end of the conveying coil, and the output end of the air jet mechanism is connected to the inside of the conveying coil. The outlet of the output pipe is provided with a rectangular drain nozzle. The connection between the rectangular drain nozzle and the inside of the output pipe forms a conical converging cavity. The inner walls of the conical converging cavity are symmetrically provided with arc-shaped guide grooves on both sides. A crushing roller is installed between adjacent arc-shaped guide grooves. The crushing roller is driven by a motor to rotate. The inner wall of the conveying coil is equipped with multiple cutting blades.

[0008] In addition, a preferred structure is that a motor is installed on the upper part of the processing chamber, and the output end of the motor extends into the interior of the processing chamber and is connected to a stirring shaft.

[0009] In addition, a preferred configuration is that an electrically controlled valve is provided between the processing chamber and the conveying coil, and the electrically controlled valve is opened and closed by the machine body.

[0010] In addition, a preferred structure is that a slurry tank is provided on one side of the machine body, and the highest slurry level in the slurry tank is lower than the position of the outlet at the end of the output pipe.

[0011] In addition, a preferred structure is that a second motor is installed on the upper part of the output tube, and the output end of the second motor extends into the inside of the output tube and is connected to a crushing roller.

[0012] The beneficial effects of this utility model are as follows: In this invention, the conveying coil is equipped with an air jet mechanism to accelerate the flow rate of the slurry inside. After the slurry has completed the initial stirring and separation, the cutting blades inside the conveying coil achieve a secondary crushing effect. A rectangular discharge nozzle and a crushing roller mechanism are set at the output pipe to accelerate the slurry outlet flow rate while crushing it. This significantly improves the crushing and separation effect on the basis of traditional mechanical stirring, ensuring the quality and efficiency of recycling. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4A recycling device for high-wet-strength damaged household paper includes a machine body 1. A processing chamber 2 is provided on one side of the machine body 1. The bottom outlet of the processing chamber 2 is connected to the upper input port of the conveying coil 4. An output pipe 41 is connected to one side of the bottom of the conveying coil 4. The output pipe 41 is connected to the pulp tank 11 inside the machine body 1. An air jet mechanism 3 is connected to the bottom end of the conveying coil 4, and the output end of the air jet mechanism 3 is connected to the inside of the conveying coil 4. The outlet of the output pipe 41 is provided with a rectangular drain nozzle 8. The rectangular drain nozzle 8 and the internal connection of the output pipe 41 form a conical converging cavity. When the slurry enters the rectangular drain nozzle 8 through the output pipe 41, the flow rate increases. Among them, the inner wall of the conical gathering cavity is symmetrically provided with arc-shaped guide grooves 7 on both sides, and a crushing roller 51 is installed between adjacent arc-shaped guide grooves 7. The crushing roller 51 is driven to rotate by motor 5, and a certain gap is left between the crushing roller 51 and the arc-shaped guide groove 7 for the slurry to pass through.

[0017] The inner wall of the conveying coil 4 is provided with multiple cutting blades 42. When the pulp flows through the conveying coil 4 at an accelerated speed, the cutting blades 42 come into contact with and crush the paper damage in the pulp.

[0018] A motor 21 is installed on the upper part of the processing chamber 2. The output end of the motor 21 extends into the interior of the processing chamber 2 and is connected to a stirring shaft 22.

[0019] An electric control valve 6 is installed between the processing chamber 2 and the conveying coil 4. The electric control valve 6 is electrically controlled to open and close by the body 1. This is a conventional configuration in the field and will not be explained further.

[0020] A slurry tank 11 is provided on one side inside the machine body 1. The highest slurry level in the slurry tank 11 is lower than the position of the outlet at the end of the output pipe 41.

[0021] A second motor 5 is installed on the upper part of the output pipe 41. The output end of the second motor 5 extends into the inside of the output pipe 41 and is connected to a crushing roller 51.

[0022] In this embodiment, after the slurry is initially stirred and broken by the stirring shaft 22 in the treatment chamber 2, the electric control valve 6 is opened by the machine body 1 to introduce the slurry into the conveying coil 4 below.

[0023] At the same time, the jetting mechanism 3 located at the bottom of the conveying coil 4 injects inert gas at high speed into the pipe at the end of the coil, using airflow to accelerate the flow rate of the slurry at the output pipe 41, causing it to flow faster in the spiral pipe. During this process, the slurry collides and shears violently with multiple cutting blades 42 set on the inner wall of the pipe, further enhancing the crushing effect.

[0024] Subsequently, the slurry is discharged through the output pipe 41 and guided by the rectangular discharge nozzle 8 at its end, and comes into contact with the crushing roller 51 at the position of the arc-shaped guide groove 7. The crushing roller 51 is driven by the motor 5, and its rotation direction is opposite to the slurry flow direction, thereby forming a reverse shearing effect on the discharged slurry and realizing efficient secondary crushing.

[0025] Finally, the thoroughly crushed slurry is discharged into slurry tank 11, completing the entire processing procedure.

[0026] The jetting mechanism 3 includes an external inert gas source and a gas booster. The output end of the gas booster is connected to the delivery coil 4 to output gas. This is easy to understand intuitively and will not be explained further.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
