Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to an ultrasonic vibrating screen. Background Art

[0002] An ultrasonic vibrating screen is a screening device that combines traditional vibrating screens and ultrasonic technology. By the high-frequency vibration of ultrasonic waves, it prevents fine particulate materials from adhering to and clogging the screen mesh, thereby improving the screening efficiency and accuracy. It is particularly suitable for screening fine and difficult-to-process materials and is widely used in industries such as pharmaceuticals, food, and chemicals.

[0003] When an ultrasonic vibrating screen is in use, materials need to be fed from the top feeding port. However, the materials can only be fed at a fixed angle, resulting in the accumulation of materials on the surface of the screen mesh. This not only affects the screening efficiency but also causes uneven stress on the screen mesh, easily reducing its service life. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an ultrasonic vibrating screen that can evenly distribute materials on the screen mesh, improve the screening effect, and extend the service life of the screen mesh.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] An ultrasonic vibrating screen includes a screen box. Inside the screen box, a plurality of screen meshes are arranged. On the upper surface of the top feeding port of the screen mesh, a disc is rotatably installed. Inside the disc, a feeding pipe is penetrated. At the bottom of the feeding pipe, a hose is installed. At the bottom of the hose, a discharging pipe is installed. On the outer surfaces of both sides of the feeding pipe, side plates are installed. Both side plates are rotatably connected to the discharging pipe through connecting shafts. On the outside of one of the side plates, a swinging mechanism is provided that can drive the discharging pipe to swing reciprocally. On the outer surface of the screen box, a rotating mechanism is provided that can drive the disc to rotate.

[0007] Thus, due to the good deformation ability of the hose, the discharging pipe can change its angle. Therefore, the discharging pipe can be driven to swing reciprocally by the swinging mechanism and, in combination with the setting of the rotating mechanism, drive the disc to rotate. As a result, when feeding materials into the feeding pipe, the materials can be evenly distributed on the entire surface of the screen mesh, avoiding local accumulation. This not only improves the screening efficiency but also makes the stress on the screen mesh surface uniform, avoiding excessive fatigue in certain areas, thereby extending the service life of the screen mesh. Moreover, the uniform stress on the screen mesh can optimize the vibration transmission effect, reduce energy waste, and improve the overall operating energy efficiency.

[0008] Further, the rotating mechanism includes a first bevel gear installed at the end of the connecting shaft. A rotating shaft penetrates through and is rotatably connected to the inside of the disc. A second bevel gear is installed at the bottom of the rotating shaft. The second bevel gear is meshed with the first bevel gear. A rotating gear is installed at the top of the rotating shaft. An electric push rod is installed on the upper surface of the disc. A toothed plate is installed at the end of the telescopic end of the electric push rod. The toothed plate is meshed with the rotating gear.

[0009] When the electric push rod is started to make its telescopic end reciprocate telescopically, it can drive the toothed plate to reciprocate telescopically. Since the toothed plate is meshed with the rotating gear, the rotating shaft can be driven to rotate back and forth, and through the meshing relationship between the second bevel gear and the first bevel gear, the connecting shaft can drive the blanking pipe to achieve the purpose of reciprocating swing.

[0010] Further, the rotating mechanism includes a motor installed on the outer surface of the screening box. A driving gear is installed at the end of the output shaft of the motor. A toothed ring is sleeved on the outer surface of the disc. The toothed ring is meshed with the driving gear.

[0011] When the motor is started, its output shaft drives the driving gear to rotate. Since the driving gear is meshed with the toothed ring, the purpose of driving the disc to rotate is achieved.

[0012] Further, four first convex blocks are coaxially and arrayedly installed at the bottom of the screening box. Universal wheels are installed at the bottoms of the first convex blocks.

[0013] Through the setting of the universal wheels, the device can be easily pushed to move, which is convenient for adjusting and repositioning the device in the production workshop, thereby improving the operation flexibility.

[0014] Further, four second convex blocks are coaxially and arrayedly installed at the bottom of the screening box. A screw rod penetrates through and is threadedly connected to the inside of the second convex block. A support pad is installed at the bottom of the screw rod. A hand wheel is installed at the top of the screw rod.

[0015] When the device is moved to the designated position, the hand wheel can be rotated to drive the screw rod to rotate, so that the support pad can descend and support the ground, thereby enabling the device to obtain good stability.

[0016] Further, a housing is installed on the outer surface of one of the side plates. The housing is arranged outside the first bevel gear and the second bevel gear.

[0017] Through the setting of the housing, the meshing part of the first bevel gear and the second bevel gear can be protected, avoiding materials from adhering to the first bevel gear and the second bevel gear and affecting their meshing transmission. Description of the Drawings

Specific embodiments

[0023] The present utility model will be described in detail below with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, an ultrasonic vibrating sieve includes a sieve box 100. A plurality of sieve meshes 101 are arranged inside the sieve box 100. A disc 102 is rotatably installed on the upper surface of the feeding port at the top of the sieve mesh 101. A feeding pipe 103 penetrates through the inside of the disc 102. A hose 104 is installed at the bottom of the feeding pipe 103. A blanking pipe 105 is installed at the bottom of the hose 104. Side plates 106 are installed on the outer surfaces of both sides of the feeding pipe 103. Both side plates 106 are rotatably connected to the blanking pipe 105 through a connecting shaft 107. A swinging mechanism 200 capable of driving the blanking pipe 105 to swing reciprocally is arranged outside one of the side plates 106. A rotating mechanism 300 capable of driving the disc 102 to rotate is arranged on the outer surface of the sieve box 100.

[0025] In use, the swinging mechanism 200 and the rotating mechanism 300 are started simultaneously. The swinging mechanism 200 drives the material discharge pipe 105 to swing reciprocally, and the rotating mechanism 300 drives the disc 102 to rotate, so that the material discharge pipe 105 rotates during the reciprocating swing. Then, the material is put into the feeding pipe 103. The material passes through the flexible pipe 104 and the material discharge pipe 105 and then falls on the screen 101. Since the angle of the material discharge pipe 105 is constantly changing, the material can be evenly distributed on the entire surface of the screen 101, avoiding local accumulation. This not only improves the screening efficiency, but also makes the force on the surface of the screen 101 uniform, avoiding excessive fatigue in some areas, thereby prolonging the service life of the screen 101. And the uniform force on the screen 101 can optimize the vibration transmission effect, reduce energy waste, and improve the energy efficiency of the overall operation.

[0026] Specifically, the rotating mechanism 300 includes a first bevel gear 201 installed at the end of the connecting shaft 107. A rotating shaft 202 penetrates and is rotatably connected to the inside of the disc 102. A second bevel gear 203 is installed at the bottom of the rotating shaft 202. The second bevel gear 203 is meshed with the first bevel gear 201. A rotating gear 204 is installed at the top of the rotating shaft 202. An electric push rod 205 is installed on the upper surface of the disc 102. A toothed plate 206 is installed at the end of the telescopic end of the electric push rod 205. The toothed plate 206 is meshed with the rotating gear 204. When the electric push rod 205 is started to make its telescopic end reciprocate, it can drive the toothed plate 206 to reciprocate. Since the toothed plate 206 is meshed with the rotating gear 204, the rotating shaft 202 can be driven to rotate back and forth, and through the meshing relationship between the second bevel gear 203 and the first bevel gear 201, the connecting shaft 107 can drive the material discharge pipe 105 to achieve the purpose of reciprocating swing.

[0027] Specifically, the rotating mechanism 300 includes a motor 301 installed on the outer surface of the screening box 100. A driving gear 302 is installed at the end of the output shaft of the motor 301. A toothed ring 303 is sleeved on the outer surface of the disc 102. The toothed ring 303 is meshed with the driving gear 302. When the motor 301 is started, its output shaft drives the driving gear 302 to rotate. Since the driving gear 302 is meshed with the toothed ring 303, the purpose of driving the disc 102 to rotate is achieved.

[0028] Specifically, four first convex blocks 400 are coaxially arranged and installed at the bottom of the screening box 100. A universal wheel 401 is installed at the bottom of the first convex block 400. Through the setting of the universal wheel 401, the device can be easily pushed to move, which is convenient for adjusting and repositioning the device in the production workshop, thereby improving the operation flexibility.

[0029] Specifically, four second bumps 500 are coaxially and arrayedly installed at the bottom of the screening box 100. A screw rod 501 penetrates through and is threadedly connected to the inside of the second bump 500. A support pad 502 is installed at the bottom of the screw rod 501, and a hand wheel 503 is installed at the top of the screw rod 501. After the device is moved to a designated position, the hand wheel 503 can be rotated to drive the screw rod 501 to rotate, so that the support pad 502 can descend and support on the ground, thereby enabling the device to obtain good stability.

[0030] Specifically, a housing 600 is installed on the outer surface of one of the side plates 106. The housing 600 is arranged outside the first bevel gear 201 and the second bevel gear 203. Through the arrangement of the housing 600, the meshing part of the first bevel gear 201 and the second bevel gear 203 can be protected, preventing materials from adhering to the first bevel gear 201 and the second bevel gear 203 and affecting their meshing transmission.

It cannot be determined that the specific implementation manners of the present utility model are only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several equivalent substitutions or obvious variations are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted for the present utility model.
