Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic vibrating screens, in particular to an ultrasonic large-particle screening structure. Background Art

[0002] An ultrasonic vibrating screen converts 220V, 50HZ or 110V, 60HZ electrical energy into 38KHZ high-frequency electrical energy, inputs it into an ultrasonic transducer, and converts it into 38KHZ mechanical vibration, so as to achieve the purpose of efficient screening and screen cleaning. On the basis of the traditional vibrating screen, this system introduces a low-amplitude and high-frequency ultrasonic vibration wave (mechanical wave) on the screen mesh, and superimposes a high-frequency and low-amplitude ultrasonic vibrator on the screen mesh. The ultra-fine powder receives a huge ultrasonic acceleration, so that the materials on the screen surface always remain in a suspended state, thereby suppressing factors such as adhesion, friction, and flat drop that cause screen clogging, solving screening problems such as strong adsorption, easy agglomeration, high static electricity, high fineness, high density, and light specific gravity, making the screening of ultra-fine powder no longer difficult, and is especially suitable for users of high-quality and fine powders.

[0003] Patent No. CN202222271187.1 discloses an ultrasonic vibrating screen device. The above ultrasonic vibrating screen device includes a feed pipe, an ultrasonic vibrating screen, a first powder flow meter, a feeding butterfly valve, a second powder flow meter, and an output material buffer bin; the ultrasonic vibrating screen includes a dust-proof cover and a middle frame assembly. The middle frame assembly forms a screening cavity and a discharge port. The dust-proof cover is covered on the screening cavity, and the dust-proof cover is provided with a feed port. The screening cavity is respectively communicated with the feed port and the discharge port. One end of the first powder flow meter is communicated with the feed port, and the feeding butterfly valve is respectively communicated with the feed pipe and the other end of the first powder flow meter; one end of the second powder flow meter is communicated with the discharge port; the output material buffer bin is communicated with the other end of the second powder flow meter; since both ends of the second powder flow meter are respectively communicated with the discharge port and the output material buffer bin, the abnormality or blockage of the ultrasonic vibrating screen can be quickly and timely detected, avoiding the problem of screen bursting. However, this device has the following problems: First, this device cannot remove the static electricity carried on the materials, which easily blocks the screening mesh and causes incomplete screening. Secondly, when this device vibrates during screening, it cannot buffer and play a stabilizing role. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problem that static electricity carried on the materials easily blocks the screening mesh and causes incomplete screening by setting up an electrostatic metal wire frame, and solve the technical problem that the device cannot buffer and play a stabilizing role when vibrating during screening by setting up shock-absorbing blocks.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An ultrasonic large-particle screening structure, characterized in that: it includes a base, an ultrasonic power supply box is provided on the lower side of the right end of the base, shock-absorbing blocks are evenly arranged around the outer side of the upper end of the base, a feeding frame is provided on the upper end of the shock-absorbing blocks, a screening wire frame is provided on the upper end of the feeding frame, an anti-static metal wire frame is provided on the upper end of the screening wire frame, an extremely fine screening net is provided at the lower end of the screening wire frame, and a transducer tube is provided at the right end of the screening wire frame.

[0007] As a preference, a groove tube is provided at the center of the right end of the ultrasonic power supply box, a connecting wire is provided at the center of the outer side of the groove tube, and the connecting wire is electrically connected to the transducer tube.

[0008] As a preference, a housing is provided on the outermost circle of the feeding frame, a feeding port is provided on the left side of the housing, an inclination angle is provided inside the feeding port, and the inclination angle inclines downward from the right side to the left side. A rotating chassis is provided at the center inside the housing, the rotating chassis is in a conical shape as a whole, and a fixing ring is provided on the outer circle of the rotating chassis.

[0009] As a preference, a rotating motor is provided at the lower end of the rotating chassis, and the rotating motor is located inside the base.

[0010] As a preference, a mounting plate is provided at the lower end of the shock-absorbing block, a mounting seat is provided at the center of the upper end of the mounting plate, a connecting column is provided at the center of the inside of the mounting seat, and a high-polymer internal damping layer is provided on the inner surface of the mounting seat.

[0011] As another preference, an activated carbon moisture absorption ring is provided on the inner wall circle of the screening wire frame.

[0012] The beneficial effects of the present utility model:

[0013] (1) In the present utility model, the static electricity carried on the material is eliminated by setting an anti-static metal wire frame to ensure the screening effect. When screening by ultrasonic vibration, the material will carry negative charges due to friction and stick together, resulting in blocked mesh. After the anti-static metal wire frame is connected to the power supply, it will release positive charges, and the positive charges will attract the negative charges of the lower-end material, so that the static electricity on the surface of the material is neutralized, achieving the purpose of eliminating the static electricity on the material, preventing blocked mesh during the screening process, and making the screening process smoother and more thorough.

[0014] (2) In the present utility model, the shock-absorbing block can play a shock-absorbing and stabilizing function during ultrasonic vibration. When screening by ultrasonic vibration, the entire device will generate vibration. The high-polymer internal damping layer inside the shock-absorbing block has excellent damping performance and can effectively absorb the vibration at the upper end, achieving the effects of reducing the amplitude and decreasing the amplitude, and ensuring the stability of the entire device.

[0015] (3) In the present utility model, an activated carbon moisture absorption ring is provided around the inner wall of the screening wire mesh frame. When the material generates moisture due to weather conditions and is prone to sticking together, resulting in unsmooth screening, the activated carbon moisture absorption ring around the inner wall of the screening wire mesh frame will adsorb the moisture of the material on the screening mesh through the property of activated carbon to absorb moisture, keeping the material dry and enabling the entire ultrasonic vibration screening process to be smoother without causing blockage.

[0016] In summary, the device has the advantages of enhancing the screening effect and performance and maintaining the stability of the device, and is particularly applicable to the technical field of ultrasonic vibrating screens. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following clearly and completely describes the technical solutions in the embodiments of the present utility model with reference to the drawings.

[0024] Embodiment 1

[0025] As Figures 1 to 5 shown, a large-sized ultrasonic particle screening structure of the present utility model is characterized in that it includes a base 1, an ultrasonic power supply box 2 is provided on the lower side of the right end of the base 1, shock-absorbing blocks 3 are evenly provided around the outer side of the upper end of the base 1, a blanking frame 4 is provided on the upper ends of the shock-absorbing blocks 3, a screening wire mesh frame 5 is provided on the upper end of the blanking frame 4, an electrostatic-removing metal mesh frame 6 is provided on the upper end of the screening wire mesh frame 5, an extremely fine screening mesh 52 is provided on the lower end of the screening wire mesh frame 5, and a transducer tube 51 is provided on the right end of the screening wire mesh frame 5.

[0026] Furthermore, a groove tube 21 is provided at the center of the right end of the ultrasonic power supply box 2. A connecting wire 22 is provided at the center of the outer side of the groove tube 21. The connecting wire 22 is electrically connected to the transducer tube 51, and the transducer tube 51 transmits the ultrasonic waves generated by the ultrasonic power supply box 2 to the ultra-fine screening mesh 52.

[0027] Furthermore, an outer shell 42 is provided on the outermost circle of the blanking frame 4. A blanking port 41 is provided on the left side of the outer shell 42. An inclination angle is provided inside the blanking port 41, and the inclination angle inclines downward from the right side to the left side to ensure the smoothness of material blanking. A rotating chassis 44 is provided at the center inside the outer shell 42, and the rotating chassis 44 is in a conical shape as a whole. When the screened material falls onto the blanking frame 4, the conical rotating chassis 44 will slide the material to the lower end through its shape to ensure that there is no residue of the material. A fixing ring 43 is provided on the outer circle of the rotating chassis 44 to increase stability.

[0028] Furthermore, a rotating motor 441 is provided at the lower end of the rotating chassis 44. When the rotating motor 441 works, it will drive the rotating chassis 44 to rotate at a high speed. While the rotating chassis 44 rotates at a high speed, it will transmit the material to the blanking port 41 through the rotational force for blanking. The rotating motor 441 is located inside the base 1.

[0029] Furthermore, a mounting plate 31 is provided at the lower end of the shock-absorbing block 3. A mounting seat 32 is provided at the center of the upper end of the mounting plate 31. A connecting column 321 is provided at the center inside the mounting seat 32. A high-polymer inner damping layer 322 is provided on the inner surface of the mounting seat 32. The high-polymer inner damping layer 322 has excellent damping performance and can effectively absorb the vibration from the upper end, achieving the effects of reducing the amplitude and ensuring the stability of the entire device.

[0030] Furthermore, an activated carbon moisture-absorbing ring 53 is provided in a circle on the inner wall of the screening wire frame 5. When the material becomes damp due to weather conditions and is likely to stick together, resulting in unsmooth screening, the activated carbon moisture-absorbing ring 53 on the inner wall of the screening wire frame 5 will absorb the moisture of the material on the ultra-fine screening mesh 52 through the moisture-absorbing property of activated carbon, keeping the material dry and ensuring that the entire ultrasonic vibration screening process can proceed smoothly without causing blockages.

[0031] Working process: First, place the material on the extremely fine screening mesh 52 at the lower end inside the screening wire mesh frame 5. Then, the ultrasonic power supply box 2 generates ultrasonic waves. At the same time, the transducer tube 51 transmits the ultrasonic waves generated by the ultrasonic power supply box 2 to the extremely fine screening mesh 52, causing the extremely fine screening mesh 52 to generate high-frequency vibrations, thereby driving the material to also undergo tiny vibrations to achieve the purpose of screening. The material vibrates and falls onto the blanking rack 4 through the extremely fine screening mesh 52. When the screened material falls onto the blanking rack 4, the conical rotating chassis 44 slides the material to the lower end through its conical shape to ensure that there is no residue of the material. Then, when the rotating motor 441 works, it drives the rotating chassis 44 to rotate at a high speed. While the rotating chassis 44 rotates at a high speed, it transmits the material to the blanking port 41 through the rotational force for blanking. The material may carry negative charges due to friction and stick together, resulting in mesh blockage. After the static electricity metal wire mesh frame 6 is connected to the power supply, it releases positive charges, and the positive charges attract the negative charges on the lower-end material, thereby neutralizing the static electricity on the surface of the material to achieve the purpose of eliminating the static electricity on the material, preventing mesh blockage during the screening process, and making the screening process smoother and more thorough. When the material is prone to sticking together due to moisture caused by weather conditions, resulting in unsmooth screening, the activated carbon moisture-absorbing ring 53 around the inner wall of the screening wire mesh frame 5 absorbs the moisture of the material on the extremely fine screening mesh 52 through the moisture-absorbing property of activated carbon, keeping the material dry, so that the entire ultrasonic vibration screening process can be smooth without causing blockage.

[0032] Secondly, when screening is performed through ultrasonic vibration, the entire device will generate vibrations. The high-polymer internal damping layer 322 inside the shock-absorbing block 3 has excellent damping performance and can effectively absorb the vibrations from the upper end, achieving the effects of reducing the amplitude and decreasing the amplitude, thus ensuring the stability of the entire device.
