[0002] The hydroentanglement reinforcement machine is called a hydroentanglement machine, which is mainly composed of a hydroentanglement head conveying mesh curtain, a drying device and a water circulation treatment system. The fan is one of the important components of the hydroentanglement machine drying device. The hot air transfers heat to the hydroentangled fiber web through the suction action of the fan to evaporate water, so as to fully exchange heat and improve the drying efficiency.

[0003] When the hydroentanglement fan is working, hot air is sucked in through the rotational kinetic energy of the impeller. The general impeller structure is relatively simple, and the blades are usually arranged vertically on the periphery of the impeller. Not only is the working efficiency low, but it is also easy to generate loud noise when rotating and sucking in hot air. Utility Model Content

[0006] Preferably, auxiliary blades are evenly arranged on one side of the auxiliary wheel disc, and the auxiliary blades are distributed in a concentric circle structure around the auxiliary wheel disc, and 12 groups of the auxiliary blades and the blade bodies are arranged.

[0007] Preferably, an annular reinforcement cavity is provided inside the front ring, and reinforcement plates are distributed in a concentric circle structure inside the annular reinforcement cavity.

[0008] Preferably, the blade bodies are all in an arc-shaped structure and are fixed on the rear fixing plate, and a first air duct is formed between the blade bodies, and the opening size of the first air duct gradually decreases from the outside to the inside.

[0009] Preferably, a shaft disc hub is arranged on the outer side of the shaft hole, and balancing ribs are arranged inside the shaft disc hub, and the angles between the balancing ribs are all 90°.

[0010] Preferably, the auxiliary blades have the same rotation direction as the blade body, and second air ducts are formed between the auxiliary blades.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The impeller of the new hydroentanglement fan is installed with an impeller body, which includes a rear fixing plate, a front ring, a blade body and an axial hole. The output end of the motor in the hydroentanglement fan is connected and fixed to the axial hole through a shaft body. When the impeller body is driven to rotate, the hot air is sucked in by the kinetic energy generated by the rotation of the blade body. The blade bodies are all curved in structure, and their bending direction is toward the outer edge of the impeller body. A first air duct is formed between the blade bodies. The opening size of the first air duct gradually decreases from the outside to the inside, so that the blade body can better resist wind force, reduce deformation and damage of the blade body, and improve the reliability and stability of the impeller body.

The auxiliary blades rotate in the same direction as the blade body. The airflow generated by the rotation of the auxiliary blades flows along the second air duct to the first air duct, and moves together with the airflow generated by the rotation of the blade body, thereby increasing the wind pressure and wind force of the entire impeller body, thereby improving the performance of the hydroentanglement blower. This is achieved without increasing the motor power, reducing power consumption and playing a role in energy conservation and emission reduction.

[0014] (3) The impeller of the new hydroentanglement blower is provided with an annular reinforcement cavity inside the front ring, and reinforcement plates are distributed in a concentric circle structure inside the annular reinforcement cavity, so as to improve the structural strength of the front ring and reduce the resonance of the impeller body when it rotates at high speed, thereby further reducing the generation of noise. At the same time, balancing ribs are evenly arranged inside the shaft disc hub to balance the axial force on the shaft disc hub when the impeller body rotates, increase the strength of the shaft disc hub, and make it less likely to deform.

[0024] The axial force on the shaft disc hub 11 is balanced when the impeller body 1 rotates, thereby increasing the strength of the shaft disc hub 11 and making it less likely to deform;

A front ring 3 is provided on the side of the impeller body 1 away from the rear fixing plate 4, and the front ring 3 is connected to one end of the blade body 5.

[0026] When the motor in the spunlaced blower drives the impeller body 1 to rotate, the kinetic energy generated by the rotation of the blade body 5 sucks in the hot air and transfers the heat to the spunlaced fiber web;

[0027] The blade bodies 5 are all fixed on the rear fixing plate 4 in an arc-shaped structure, and a first air duct 8 is formed between the blade bodies 5. The opening size of the first air duct 8 gradually decreases from the outside to the inside;

[0028] The blade body 5 can better resist wind force, reduce deformation and damage of the blade body 5, and thus improve the reliability and stability of the impeller body 1;

[0031] The auxiliary blades 9 rotate in the same direction as the blade body 5, and a second air duct 13 is formed between the auxiliary blades 9;

[0032] The airflow generated by the rotation of the auxiliary blades 9 flows along the second air duct 13 to the first air duct 8, and moves together with the airflow generated by the rotation of the blade body 5, thereby increasing the wind pressure and wind force of the entire impeller body 1, thereby improving the performance of the water jet blower, without increasing the motor power, reducing power consumption, and playing a role in energy saving and emission reduction;

[0033] An annular reinforcement cavity 14 is provided inside the front ring 3, and reinforcement plates 15 are distributed in a concentric circle structure inside the annular reinforcement cavity 14, which improves the structural strength of the front ring 3 and reduces the resonance of the impeller body 1 during high-speed rotation, thereby further reducing the generation of noise.

[0034] Working principle: When the embodiment of the present application is in use, the output end of the motor in the spunlaced blower is connected and fixed to the shaft hole 6 in the central part of the impeller body 1 through the shaft body. A shaft disk hub 11 is arranged outside the shaft hole 6, and balancing ribs 12 are evenly arranged inside the shaft hole 6 to balance the axial force exerted on the shaft disk hub 11 when the impeller body 1 rotates, thereby increasing the strength of the shaft disk hub 11 and making it less likely to deform.

The rotation direction of the auxiliary wheel disc 2 is consistent with that of the blade body 5, so that the airflow generated when the auxiliary blades 9 rotate flows along the second air duct 13 to the first air duct 8, and moves together with the airflow generated by the rotation of the blade body 5, thereby increasing the wind pressure and wind force of the entire impeller body 1, and thus improving the performance of the water spunlace blower, without increasing the motor power to achieve this, reducing power consumption, and playing a role in energy conservation and emission reduction. In addition, an annular reinforcement cavity 14 is opened inside the front ring 3, and reinforcement plates 15 are distributed in a concentric circle structure inside the annular reinforcement cavity 14, which improves the structural strength of the front ring 3 and reduces the resonance of the impeller body 1 when the high-speed rotation occurs, thereby further reducing the generation of noise.
