Description

Technical Field

[0001] This utility model relates to a resin vacuum material dust removal hopper. Background Technology

[0002] Vacuum feeders are widely used in the conveying and processing of granular materials such as resins. However, existing vacuum feeders have several problems: on the one hand, resin particles easily generate a large amount of static electricity during conveying, and electrostatic adsorption makes it difficult to separate dust, reducing dust removal efficiency; on the other hand, if the resin feeding speed is too fast, dust and resin particles cannot be fully separated, further affecting the dust removal effect. In addition, traditional equipment requires a separate offline ion dust collector for pre-treatment of the resin, which increases equipment costs and floor space, and the process is cumbersome.

[0003] CN213864394U discloses a plastic particle dust collection and feeding machine, which includes a suction component, a suction component, and a dust collection component. The suction component has a suction chamber inside, an air outlet at the top, an air inlet tangentially arranged in the suction component, and a discharge port at the bottom. The air outlet, air inlet, and discharge port are all connected to the suction chamber. The suction component is connected to the suction chamber through the air outlet and can generate a suction airflow to create a negative pressure in the suction chamber, thereby drawing plastic particles into the chamber through the air inlet. The dust collection component is located at the bottom of the suction component and is connected to the discharge port. The dust collection component includes a dust collection sleeve and a corona wire. The dust collection sleeve is coaxially arranged below the discharge port, and the corona wire is coaxially arranged inside the dust collection sleeve. An electrostatic field can be generated between the corona wire and the dust collection sleeve, so that the dust collection sleeve can adsorb dust passing through the space between the corona wire and the dust collection sleeve.

[0004] This utility model aims to remove dust from plastic particles while feeding by setting a corona wire and a dust collection sleeve at the feeding port of the suction machine. However, its efficiency in eliminating static electricity and removing dust is extremely low when facing the conveying of large quantities of plastic particles (resin).

[0005] Therefore, a resin vacuum material dust collector hopper is proposed to address the above problems. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a resin vacuum material dust collector hopper, comprising a shell, an annular ion air knife, a vibrating screen assembly, and a dust collection assembly;

[0008] The upper end of the outer shell is provided with a feed inlet and the lower end is provided with a discharge outlet. The annular ion air knife is connected to the outer wall of the feed inlet. The vibrating screen assembly is located inside the outer shell, and the dust collection assembly is connected to the inside of the outer shell.

[0010] The second screen is disposed at the lower end of the inner shell, and the second screen is connected to a vibration motor via a vibration source.

[0011] Preferably, the dust collection assembly includes a dust collection bin disposed on the outside of the housing, one end of the dust collection bin is connected to the vacuum cleaner unit, and the other end is connected to the vacuum suction pipe, which extends into the inside of the housing.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This resin vacuum material dust collector hopper effectively solves the dust removal problem caused by high static electricity in resin by setting an annular ion air knife to eliminate static electricity, thus improving dust removal efficiency. By setting a curved second screen and combining it with high-frequency vibration, the resin feeding speed is effectively controlled, and at the same time, the dust and resin particles are fully separated, further improving the dust removal effect.

[0016] This resin vacuum material dust collector integrates electrostatic elimination, screening dust removal, and material suction functions, eliminating the need for a separate offline ion dust collector, simplifying the process, and reducing equipment costs and floor space. Its rational structural design and convenient operation enable stable and efficient vacuum material suction and dust removal of resin particles, demonstrating excellent practicality and potential for widespread application.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1 A resin vacuum material dust collector includes a shell 1, an annular ion air knife 2, a vibrating screen assembly, and a dust collection assembly; the upper end of the shell 1 is provided with a feed inlet 3 and the lower end is provided with a discharge outlet 4, and the annular ion air knife 2 is connected to the outer wall of the feed inlet 3; the vibrating screen assembly is located inside the shell 1, and the dust collection assembly is connected to the inside of the shell 1.

[0022] Specifically, an annular ion air knife 2 is installed above the hopper. Before the resin enters the hopper, it passes through the annular ion air knife 2. The ion air flow generated by the ion air knife neutralizes the static electricity on the surface of the resin particles, eliminates electrostatic adsorption, and provides good conditions for subsequent dust removal.

[0023] Specifically, during installation, the annular ion air knife 2 should be fixedly installed at a suitable position above the feed inlet 3 to ensure that the resin can completely pass through the effective area of ​​the ion air knife when entering the hopper. Connect the power supply and control system of the annular ion air knife to ensure its normal operation.

[0024] Specifically, the vibrating screen assembly includes a first screen 5 and a second screen 6; the first screen 5 is connected to the upper part of the inner casing 1; the second screen 6 is disposed at the lower part of the inner casing 1, and the second screen 6 is connected to the vibrating motor 8 through a vibration source 7. The second screen 6 has a curved shape. It also includes a power supply 13, which is located on the outside of the casing 1 and connected to the vibrating motor 8 via wiring.

[0025] Specifically, the first screen 5 has an aperture of 5-7mm. After the resin passes through the first screen 5 to initially filter out larger impurities, it enters the ultrasonic vibration chamber. A second screen 6 is installed below the ultrasonic vibration chamber. This screen has a curved shape, higher in the center and lower around the edges, with apertures of 5-7mm around the edges and 1-2mm in the center. An ultrasonic vibration motor and vibration source 7 are located below the second screen 6. Under external power control, the vibration motor 8 and vibration source 7 drive the second screen 6 to vibrate at high frequency. Under the high-frequency vibration of the second screen 6, resin particles fall downwards along the perimeter of the vibrating screen to the discharge port 4, while dust on the surface of the resin particles is drawn into the dust collection bin 9 from the central area of ​​the second screen 6 under the action of vibration and negative pressure, achieving efficient separation of resin and dust.

[0026] Specifically, the dust collection component includes a dust collection bin 9, which is located on the outside of the outer casing 1. One end of the dust collection bin 9 is connected to the vacuum cleaner unit 10, and the other end is connected to the suction pipe 12, which extends into the interior of the outer casing 1. By combining vibration with suction, the dust separation effect is enhanced, and the dust removal efficiency is improved.

[0027] Specifically, it also includes an upper limit sensor 14, a lower limit sensor 15, and a suction machine 16; the upper limit sensor 14 and the lower limit sensor 15 are respectively connected to the upper end of the inner wall of the housing 1; the suction machine 16 is connected to the upper end of the inner wall of the housing 1 through the suction pipe 17.

[0028] Specifically, when the resin height inside the housing reaches the upper limit, the sensor triggers a signal to control the feeder to stop feeding; when the resin height is below the lower limit, the sensor triggers a signal to control the feeder 16 to start feeding, thus achieving automatic and precise feeding control and ensuring a stable resin level in the storage chamber.

[0029] During operation, after the resin enters the storage chamber, the suction machine 16 automatically performs suction operation according to the resin height in the storage chamber. After the resin is initially filtered by the first screen 5, it enters the ultrasonic vibration chamber. Under the high-frequency vibration of the second screen 6, the resin particles fall along the perimeter of the second screen 6 to the discharge port 4, while the dust is sucked into the dust collection bin 9 from the central area, achieving efficient dust removal and material conveying.

[0030] This resin vacuum material dust collector hopper effectively solves the dust removal problem caused by high static electricity in resin by eliminating static electricity through the installation of annular ion air knives, thus improving dust removal efficiency. The curved second screen 6, combined with high-frequency vibration, effectively controls the resin feeding speed and achieves thorough separation of dust and resin particles, further enhancing the dust removal effect.

[0031] This resin vacuum material dust collector integrates electrostatic elimination, screening dust removal, and material suction functions, eliminating the need for a separate offline ion dust collector, simplifying the process, and reducing equipment costs and floor space. Its rational structural design and convenient operation enable stable and efficient vacuum material suction and dust removal of resin particles, demonstrating excellent practicality and potential for widespread application.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
