Description

Technical Field

[0001] This utility model relates to the field of ultrasonic vibrating screen technology, and specifically to an ultrasonic vibrating screen with a long service life. Background Technology

[0002] An ultrasonic vibrating screen is a fine screening device that uses high-frequency ultrasonic vibration technology to improve screening efficiency. It generates high-frequency micro-amplitude vibrations through ultrasonic transducers attached to the screen mesh, which effectively decomposes material agglomeration and reduces screen hole clogging. It is especially suitable for screening high-viscosity, static-prone, or ultrafine powders.

[0003] Before materials are fed into the ultrasonic vibrating screen, the storage environment may cause them to become damp. During the screening process, damp materials are prone to clumping due to moisture, adhering to the screen surface and gradually clogging the screen holes. As the effective screening area of ​​the screen plate decreases, the material throughput rate drops significantly, leading to a decrease in screening efficiency and even forcing a shutdown for cleaning, affecting the continuity of production. Furthermore, long-term residual damp materials may breed microorganisms or undergo deterioration reactions after mixing with other materials, affecting product purity. If the cleaning is not handled properly during shutdown, the residue may also contaminate the next batch of materials. Therefore, an ultrasonic vibrating screen with a long service life is proposed to solve the above problems. Utility Model Content

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-6As shown, a long-life ultrasonic vibrating screen includes an ultrasonic vibrating screen body 1, with a feeding mechanism 2 at the upper end of the ultrasonic vibrating screen body 1. The ultrasonic vibrating screen body 1 includes a shell 101, with a screen plate 102 disposed in the middle of the inner wall of the shell 101, and a discharge pipe 103 passing through and fixedly connected to the side of the shell 101. The feeding mechanism 2 includes a storage box 201, with the middle of the outer wall of the storage box 201 abutting against the top surface of the shell 101. Support rods 203 are symmetrically fixedly connected to the lower inner side of the storage box 201, and a vertical cylinder 206 is fixedly connected between the two support rods 203. A support block 202 is fixedly connected to the inner wall of the storage bin 201 and above the support rod 203; several air supply pipes 207 are fixedly and continuously connected to the upper end of the outer wall of the vertical cylinder 206, and several upper exhaust ports 208 are opened on the bottom surface of each air supply pipe 207, and the upper exhaust ports 208 are equidistantly arranged along the length of the air supply pipe 207, and a cover 209 is fixedly connected to the top of each air supply pipe 207; several lower exhaust ports 210 are opened at the lower end of the outer wall of the vertical cylinder 206, and the lower exhaust ports 210 are equidistantly arranged around the surface of the vertical cylinder 206, such as Figure 3 As shown, the width of the canopy 209 is greater than the diameter of the gas pipe 207, so that when the material is fed, the material slides down to both sides along the upper surface of the canopy 209, avoiding the material from contacting the lower exhaust port 210.

[0025] A rotating ring 212 is movably contacted on the top surface of the vertical cylinder 206. An air inlet pipe 213 is rotatably connected to the middle of the rotating ring 212. A hollow pipe 214 is fixedly and continuously connected to the bottom of the rotating ring 212. A sealing ring 218 is fixedly connected to the bottom surface of the hollow pipe 214. The bottom surface of the sealing ring 218 abuts against the bottom surface of the inner wall of the vertical cylinder 206. Figure 5 As shown, the sealing ring 218 is made of silicone, which can reduce the connection gap between the hollow tube 214 and the bottom of the inner wall of the vertical cylinder 206, thereby preventing airflow from leaking out through the lower exhaust port 210.

[0026] The upper end of the outer wall of the hollow tube 214 is provided with a thread 215, and an annular groove 216 is formed in the middle of the outer wall of the hollow tube 214. Several through holes 217 are formed on the surface of the hollow tube 214 and inside the annular groove 216. The outer wall of the hollow tube 214 is threaded to the inner side of the vertical cylinder 206 through the thread 215, and the annular groove 216 and each gas pipe 207 are located on the same horizontal plane. An inner support plate 211 is also fixedly installed in the middle of the outer wall of the vertical cylinder 206. Figure 2 As shown, the annular groove 216 accommodates the airflow between the gas pipe 207 and the through hole 217, thereby preventing the annular groove 216 from being misaligned with the gas pipe 207 and thus causing airflow blockage.

[0027] A top cover 204 is movably installed on the top surface of the storage bin 201. An outer support plate 205 is fixedly installed on the outer side of the bottom surface of the top cover 204. A bin door 219 is rotatably connected to one side of the top surface of the top cover 204. Figure 2 As shown, when the door 219 is closed, it can prevent material dust from floating upwards;

[0028] The bottom surface of the outer support plate 205 abuts against the support block 202, the inner side of the outer support plate 205 abuts against the inner support plate 211, the outer wall of the outer support plate 205 is slidably fitted with the inner wall of the storage box 201, the middle part of the top cover 204 penetrates and is slidably connected to the surface of the vertical cylinder 206, and the lower end of the vertical cylinder 206 extends to below the bottom surface of the storage box 201. Figure 1 As shown, there is a gap between the bottom of the vertical cylinder 206 and the sieve plate 102 to prevent the sieve plate 102 from colliding with the vertical cylinder 206.

[0029] The working principle of this utility model:

[0030] When using the device, flip open the box door 219 and put the material into the storage box 201. At this time, the material is supported by the inner support plate 211 and the outer support plate 205. Then, connect the output pipe of the electric hot air blower to the air inlet pipe 213. Hot air enters the hollow pipe 214 and is discharged through the through hole 217, so the hot air enters the air delivery pipe 207. Finally, it is blown down onto the material through the upper exhaust port 208, thereby assisting the material to be dried. After drying for a period of time, the top cover 204 can be lifted, so that the outer support plate 205 is moved to the inner side to be misaligned with the inner support plate 211. The material falls through the gap onto the screen plate 102 inside the ultrasonic vibrating screen body 1. At this time, the external control device of the ultrasonic vibrating screen body 1 can be started and the screen plate 102 can be driven to vibrate. When there is a blockage on the surface of the screen plate 102, the hollow tube 214 is rotated by the rotating ring 212 and pushed by the screw 215, which drives the hollow tube 214 to rise along the inner side of the vertical cylinder 206. Thus, each through hole 217 is misaligned with the air supply pipe 207, and a gap is formed between the bottom of the hollow tube 214 and the bottom of the inner wall of the vertical cylinder 206. Then, hot air can enter the hollow tube 214 through the bottom of the hollow tube 214 and finally be discharged through the lower exhaust port 210. At this time, the hot air blows the material above the screen plate 102 to prevent the material from staying in a certain area for a long time.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
