[0006] To achieve the above objectives, the present invention provides the following technical solution: a filtration and impurity removal device for the preparation of nonwoven fabrics, comprising a pressure chamber, wherein a pressure filtration mechanism is provided on the pressure chamber;

[0007] The pressurized filtration mechanism includes a booster pump fixedly installed on the upper surface of the pressurized chamber.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 4 This embodiment of a filtration and impurity removal device for nonwoven fabric preparation includes a pressure chamber 1. A feed pipe 14 is fixedly installed on the top of the pressure chamber 1. The inside of the feed pipe 14 is connected to the inner cavity of the pressure chamber 1, which facilitates the injection of materials into the pressure chamber 1. The outer shape of the pressure chamber 1 is cylindrical, and the bottom surface of the pressure chamber 1 is conical. The minimum diameter of the bottom of the pressure chamber 1 is the same as the diameter of the discharge pipe 6, which facilitates the entry of materials in the pressure chamber 1 into the discharge pipe 6 and helps to prevent materials from remaining in the corners of the pressure chamber 1.

[0031] The pressurization chamber 1 is equipped with a pressurization and filtration mechanism, which includes a booster pump 2 fixedly installed on the upper surface of the pressurization chamber 1. An air inlet bend 3 connected to the inside of the pressurization chamber 1 is fixedly installed at the air outlet end of the booster pump 2. A one-way air outlet valve 4 is fixedly installed at the end of the air inlet bend 3 away from the booster pump 2. A controller 5 is fixedly installed on the surface of the pressurization chamber 1. A discharge pipe 6 is fixedly installed at the bottom of the pressurization chamber 1. A first filter discharge pipe 7 is threadedly connected to the bottom of the discharge pipe 6. A first conical mesh filter bucket 8 is fixedly installed inside the first filter discharge pipe 7. A second filter discharge pipe 9 is threadedly connected to the bottom of the first filter discharge pipe 7. A second conical mesh filter bucket 10 is fixedly installed inside the second filter discharge pipe 9. A third filter discharge pipe 11 is threadedly connected to the bottom of the second filter discharge pipe 9. A third conical mesh filter bucket 12 is fixedly installed inside the third filter discharge pipe 11. Pressure sensors 13 are fixedly installed inside the first conical mesh filter bucket 8, the second conical mesh filter bucket 10, and the third conical mesh filter bucket 12.

[0032] The output of controller 5 is electrically connected to the input of booster pump 2, facilitating control of the working power of booster pump 2 and the pressure input into pressurization chamber 1. The input of controller 5 is also electrically connected to the output of pressure sensor 13. This allows pressure sensor 13 to transmit the monitored internal pressures of the first filter outlet pipe 7, the second filter outlet pipe 9, and the third filter outlet pipe 11 to controller 5, enabling staff to promptly monitor changes in the internal pressures of these pipes. These changes allow for the determination of the amount of impurities accumulated inside the first conical mesh filter hopper 8, the second conical mesh filter hopper 10, and the third conical mesh filter hopper 12, thus reminding staff to clean these impurities in a timely manner.

[0033] The mesh diameter of the first conical mesh filter bucket 8 is larger than that of the second conical mesh filter bucket 10, and the mesh diameter of the second conical mesh filter bucket 10 is larger than that of the third conical mesh filter bucket 12. By using conical mesh filter buckets with different mesh diameters, impurities of different diameters can be filtered in layers, which can prevent impurities of different sizes from accumulating and causing rapid clogging of the filter bucket.

[0034] The output terminal of the controller 5 is electrically connected to the input terminal of the heating wire 15, and the heating temperature of the heating wire 15 can be easily controlled through the controller 5.

[0035] The working principle of the above embodiments is as follows:

[0036] In use, material is injected into the pressurizing chamber 1 through the feed pipe 14. The booster pump 2 is started by the controller 5, and the pressurizing chamber 1 is pressurized through the air inlet bend 3 and the one-way air outlet valve 4. This causes the material in the pressurizing chamber 1 to flow sequentially into the first filter discharge pipe 7, the second filter discharge pipe 9, and the third filter discharge pipe 11 through the discharge pipe 6. The material is then filtered sequentially through the first conical mesh filter bucket 8, the second conical mesh filter bucket 10, and the third conical mesh filter bucket 12. The pressure sensor 13 monitors the pressure inside the first filter discharge pipe 7, the second filter discharge pipe 9, and the third filter discharge pipe 11. When the pressure sensor 13 detects a pressure reading in the first filter discharge pipe 7, the second filter discharge pipe 9, and the third filter discharge pipe 11, the pressure sensor detects a pressure reading in the third filter discharge pipe 11. If the pressure inside the first filter outlet pipe 7, the second filter outlet pipe 9, or the third filter outlet pipe 11 is too high, it indicates that the material flow rate inside the first filter outlet pipe 7, the second filter outlet pipe 9, or the third filter outlet pipe 11 is too slow. This can reflect that there are more impurities inside the first conical mesh filter bucket 8, the second conical mesh filter bucket 10, or the third conical mesh filter bucket 12. The first filter outlet pipe 7, the second filter outlet pipe 9, the third filter outlet pipe 11, the first conical mesh filter bucket 8, the second conical mesh filter bucket 10, and the third conical mesh filter bucket 12 can be heated by the heating wire 15 to prevent the material from cooling and solidifying inside the first filter outlet pipe 7, the second filter outlet pipe 9, and the third filter outlet pipe 11.
