Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vibrating screening, in particular to the technical field of vibrating screening in mineral processing. BACKGROUND

[0002] With the development of society, vibrating screens have been widely used in many fields. The quality of vibrating screen equipment and the level of operation directly affect the production efficiency, the precision of materials and the degree of energy saving. Therefore, it directly affects the production cost and economic benefit of enterprises.

[0003] The spiral spring commonly used in the current vibrating screen has low stiffness, which leads to insufficient overall stiffness of the vibrating screen, and thus the traditional vibrating screen cannot amplify the amplitude by using the resonance principle, which makes it difficult to improve the screening efficiency and affects the production and economic benefit. If high-stiffness spiral springs are directly used to replace conventional spiral springs as the elastic support of the vibrating screen, the high-stiffness spiral springs are difficult to process and have high production cost, and most importantly, the stiffness is difficult to adjust, which is not conducive to mass production and popular application in equipment.

[0004] At the same time, the screen of the current common vibrating screen is an integral net fixed at four corners by bolts and has the same inclination angle as the vibrating screen box. The design scheme for fixing the inclination angle of the screen is relatively simple, which can be realized by setting a fixed connection bolt interface at the four corners of the screen box. However, the best screening inclination angle of different types, materials and particle sizes of materials is different. If a single inclination angle is used, the screening efficiency and quality will be reduced. Moreover, the traditional vibrating screen is a closed and invisible structure, which is not conducive to real-time observation of the screening state and comparison of the screening effect. If a problem occurs, the vibrating screen cannot be adjusted in time.

[0005] The patent document CN110899109A published on March 24, 2020 discloses an elastic support assembly for an inertial vibrating screen and an inertial vibrating screen thereof, which adopts a single disc spring group as the elastic support assembly. However, the single disc spring group has a small stiffness range in the vertical direction and low stiffness adjustment precision, which is not conducive to mass production and popular application in equipment. SUMMARY

[0027] Further, there is a preferred embodiment that the driving device comprises a motor, a shaft coupling, a transmission shaft, an eccentric block, a rolling bearing and a bearing seat.

[0029] The motor shaft of the motor is connected with the transmission shaft through the shaft coupling.

[0030] The eccentric block is fixed on the transmission shaft.

[0033] Further, there is a preferred embodiment that a sliding groove is arranged on the prism of the main body frame.

[0035] Further, there is a preferred embodiment that the disc spring vibrating screen further comprises a plurality of acrylic plates.

[0036] The main body frame of the vibrating screen is covered through the acrylic plates.

[0037] The beneficial effects of the present application are as follows:

[0038] 1. Existing vibrating screens usually use conventional coil springs as elastic supports. Due to the low vertical stiffness of conventional coil springs, the natural frequency of the vibrating screen supported by the coil springs is much lower than the operating frequency, and the amplitude cannot be amplified by the resonance principle. Therefore, the excitation force required to obtain the corresponding amplitude is relatively large. Excessive excitation force makes important structural components of the vibrating screen, such as the screen, screen box and bearings, extremely prone to fatigue damage, thereby reducing the reliability and service life of the vibrating screen. The present invention provides a disc spring vibrating screen with adjustable inclination angle. The disc spring is used as the elastic support element of the vibrating screen. It can increase the vertical stiffness of the vibrating screen and make the natural frequency of the vibrating screen close to the operating frequency, thereby amplifying the amplitude by the resonance principle and reducing the excitation force required to achieve the required amplitude. This effectively reduces the energy consumption of the vibrating screen and can improve the service life of important components of the vibrating screen, such as the screen, screen box and bearings. At the same time, because the disc spring elastic system is a linear vibration system, the disc spring vibrating screen has a stable vibration state when operating by the resonance principle, avoiding the problem of unstable working state caused by nonlinear vibration when the traditional composite spring resonance screen is working. Furthermore, disc springs are easily assembled, facilitating adjustment of the stiffness of vibrating screen spring elements and meeting the varying operating frequencies required by different vibrating screen models. Furthermore, the mature manufacturing process and low production costs of conventional disc springs lay the foundation for mass production and widespread adoption across various equipment.

[0039] 2. The screen of the existing vibrating screen is an integral mesh, which is an integrally formed mesh. It is fixed at the four corners by bolts and is consistent with the inclination angle of the vibrating screen box, so the screen angle is fixed. However, according to the analysis of the movement of the material on the screen, it is found that as the screening process proceeds, the optimal screening process inclination angle of the material particles in different areas of the screen is constantly changing. The screen angle of the existing vibrating screen cannot be adjusted, resulting in all material particles having to complete the screening work at the same inclination angle, which will reduce the screening efficiency and quality of the material. The present invention provides a disc spring vibrating screen with adjustable inclination angle, the vibrating screen adopts a splicing design of multiple screen sections, and each screen section is connected by a special hinge, so that the angle between each screen section can be adjusted, and the inclination adjustment range of each screen section is 0-15°, which realizes the precise adjustment of the angles of different positions within a screen, and meets the requirements of the optimal screening process inclination angle of logistics particles at different positions.

[0040] 3. The present invention provides a disc spring vibrating screen with adjustable inclination angle. The screen is connected to the screen box body using a slipknot and chute design. The chute and bolt fixation allows for vertical adjustment of the screen, with the height adjustment range covering the entire height of the screen box. The chute and slipknot are used in conjunction to adjust the screen's angles to a wide range, with an inclination adjustment range of 0-60°. This allows for a wide range of angle adjustment for the entire screen, meeting the optimal inclination requirements for particle flow.

[0041] 4. The existing elastic support assembly used for the inertial vibrating screen and the inertial vibrating screen thereof adopts a single disc spring group as the elastic support assembly, but the single disc spring group has a small vertical stiffness adjustment range and low stiffness adjustment precision, which is not conducive to mass production and popular application in equipment. The present invention provides an elastic support assembly that adopts a double disc spring group as the elastic support, and the double disc spring group is built into a double-layer triangular plate frame structure, so that it can ensure that the stiffness adjustment of the elastic element of the double disc spring group is not affected, and meet the requirements of positioning and assembly of the support element. It can also be used as a separate component to complete stiffness adjustment in advance, which is easier to improve production and assembly efficiency. Compared with the elastic support design of the single disc spring group, the elastic system support design of the double disc spring group has a larger vertical stiffness adjustment range and higher adjustable stiffness precision. At the same time, the elastic system support design of the double disc spring group has stronger bending resistance, which can effectively avoid the collision and friction between the internal guide rod of the disc spring group and the inner ring of the disc spring, thereby improving the service life and reliability of the disc spring elastic support system.

[0042] The invention is suitable for vibration screening in mineral processing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples will help those skilled in the art to further understand the present application, but do not limit the present application in any form. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, a number of changes and improvements can be made, which are within the scope of protection of the present application.

[0051] Embodiment one. Referring to Figure 1 In this embodiment, an elastic support assembly is provided, which includes a fixed bottom plate 23, a disc spring group system 22, a double layer triangular plate main frame 20 and a connecting bolt 21;

[0052] The first layer bottom plate of the double layer triangular plate main frame 20 is provided with a through hole;

[0053] The disc spring group system 22 passes through the through hole of the first layer bottom plate of the double layer triangular plate main frame 20 and is arranged on the fixed bottom plate 23;

[0054] The connecting bolt 21 passes through the fixed bottom plate 23, the first layer bottom plate and the second layer bottom plate of the double layer triangular plate main frame 20 in sequence, and is used for fixedly connecting the fixed bottom plate 23 and the double layer triangular plate main frame 20.

[0055] In actual application, as shown in Figure 1 The elastic support assembly is composed of the double layer triangular plate frame 20 and the fixed bottom plate 23 through the connecting bolt 21. Each disc spring group system 22 is positioned by an embedded positioning shaft and the nut of the loose connecting bolt 21 is used for adjusting the pre-tightening force. The elastic support assembly provides elastic support for the vibration screen sample machine, and drives the main part of the vibration screen to complete the vibration screening work under the action of the exciting force.

[0056] The existing elastic support assembly for the inertial vibrating screen and the inertial vibrating screen thereof adopt a single disc spring group as the elastic support assembly, but the single disc spring group has a small vertical stiffness adjustment range and low stiffness precision, which is not conducive to mass production and popular application in equipment. The embodiment provides an elastic support assembly, which adopts a double disc spring group as the elastic support, and embeds the double disc spring group into a double-layer triangular plate frame structure, so that the stiffness adjustment of the double disc spring group elastic element is not affected, the positioning and assembly requirements of the support element are met, and the stiffness adjustment can be completed in advance as a separate part, which is more conducive to improving the production and assembly efficiency. Compared with the single disc spring group elastic support design, the double disc spring group elastic system support design has a larger vertical stiffness adjustment range and higher adjustable stiffness precision. At the same time, the double disc spring group elastic system support design has stronger bending resistance, can effectively avoid the collision and friction between the guide rod inside the disc spring group and the inner ring of the disc spring, and improves the service life and reliability of the disc spring elastic support system.

[0057] Embodiment two. Refer to Figure 1 The embodiment is described, and the embodiment is a disc spring group system 22 in the elastic support assembly described in embodiment one, which is realized by two disc springs.

[0058] In actual application, as shown in Figure 1 The disc spring group system 22 is realized by two disc springs, and compared with the single disc spring group as the elastic support design, the double disc spring group elastic system support design has a larger vertical stiffness adjustment range and higher adjustable stiffness precision. At the same time, the double disc spring group elastic system support design has stronger bending resistance, can effectively avoid the collision and friction between the guide rod inside the disc spring group and the inner ring of the disc spring, and improves the service life and reliability of the disc spring elastic support system.

[0059] Embodiment three. Refer to Figure 1 The embodiment is described, and the embodiment is based on the elastic support assembly described in embodiment one to add a connecting upper plate 24, which is fixed on the top of the double-layer triangular plate main frame 20.

[0060] In actual application, as shown in Figure 1 The connecting upper plate 24 is fixed on the top of the double-layer triangular plate main frame 20, so that the double-layer triangular plate main frame 20 can be fixed on the vibrating screen main frame.

[0061] Embodiment four. Refer to Figure 2To illustrate the present embodiment, the present embodiment provides a disc spring vibrating screen with adjustable inclination, which is realized based on any one of the elastic support assemblies in Embodiments One to Three, and comprises a vibrating screen frame 1, an elastic support assembly 2, an adjustable inclination screen 3, a driving device 4, and a screen inclination external adjustment device 5.

[0062] The vibrating screen frame 1 comprises a main frame 10 and a base 11.

[0063] The main frame 10 is fixed on the base through the elastic support assembly 2.

[0064] The elastic support assembly is used to provide elastic support for the vibrating screen frame 1.

[0065] The driving device 4 is fixed on the main frame 10 and is used to provide inertial excitation force for the vibrating screen frame 1.

[0066] The adjustable inclination screen 3 is fixed inside the main frame 10 and is used to screen materials.

[0067] The screen inclination external adjustment device 5 is fixed on the main frame 10 and is connected with the main frame of the adjustable inclination screen 3, and is used to adjust the angle of the adjustable inclination screen 3.

[0068] In actual application, as shown in Figure 2 The elastic support element 2, the internal adjustable inclination screen 3, the driving device 4, and the screen inclination external adjustment device 5 are all installed on the vibrating screen frame 1. The vibrating screen main frame 10 is a steel truss structure and is in the shape of a cuboid. When the vibrating screen is working, the driving device 4 generates excitation force and transmits the excitation force to the vibrating screen main frame 10. The vibrating screen is composed of four elastic support assemblies 2 and a rigid base 11 to form an elastic support system, and the main frame 10 is fixed on the elastic support system 2, so that the elastic support assembly can provide elastic support for the vibrating screen frame 1. The vibrating screen main frame 10 starts to do periodic reciprocating motion under the support of the elastic support element 2, and in turn drives the internal adjustable screen 3 to vibrate, thereby providing screening power for material particles and completing the screening work. At the same time, different materials have different screening requirements, and in order to ensure the optimization of the screening effect, the screen inclination external adjustment device 5 is connected with the main frame of the adjustable inclination screen 3 and is used to adjust the angle of the adjustable inclination screen 3. The screen is adjusted to different inclination angles to meet the best screening process inclination angle requirements of the material particles on the whole screen.

[0069] The existing vibrating screen usually adopts a conventional coil spring as an elastic support. Since the vertical stiffness of the conventional coil spring is low, the inherent frequency of the vibrating screen supported by the coil spring is far lower than the working frequency, and the amplitude cannot be amplified by using the resonance principle, so a large exciting force is required to obtain the corresponding amplitude. The excessive exciting force can easily cause fatigue failure of important structural elements of the vibrating screen, such as the screen mesh, the screen box and the bearing, thereby reducing the reliability and service life of the vibrating screen. The present embodiment provides a disc spring vibrating screen with adjustable inclination, which adopts a disc spring as an elastic support element of the vibrating screen, can increase the vertical stiffness of the vibrating screen, make the inherent frequency of the vibrating screen close to the working frequency, thereby amplify the amplitude by using the resonance principle, reduce the exciting force required to reach the required amplitude, effectively reduce the working energy consumption of the vibrating screen, and improve the service life of important elements of the vibrating screen, such as the screen mesh, the screen box and the bearing. At the same time, since the disc spring elastic system is a linear vibration system, the disc spring vibrating screen has stable vibration state when working by using the resonance principle, avoiding the problem of unstable working state caused by nonlinear vibration of the traditional composite spring resonance screen. In addition, the disc spring is easy to combine, which is convenient for adjusting the stiffness of the elastic element of the vibrating screen, and can meet the needs of different models of vibrating screens for different working frequencies. Moreover, the manufacturing process of the ordinary disc spring is mature, and the production cost is low, which lays an important foundation for mass production of enterprises and popularization in different equipment.

[0070] Embodiment five. Referring to Figure 3 The present embodiment is to illustrate the screen mesh inclination external adjustment device 5 in the disc spring vibrating screen with adjustable inclination described in embodiment four. The screen mesh inclination external adjustment device 5 includes an L-shaped connecting plate 51, a slip knot nut 52, a support rod 53, a connecting buckle 54 and a connecting nut 55.

[0071] The horizontal plate of the L-shaped connecting plate 51 is provided with a through hole;

[0072] The support rod 53 passes through the through hole in the horizontal plate of the L-shaped connecting plate 51 and is fixed by the connecting nut 55;

[0073] The connecting buckle 54 is fixed to the top end of the support rod 53 by the slip knot nut 52.

[0074] In actual application, the present embodiment is Figure 3As shown, the horizontal plate of the L-shaped connecting plate is punched with a hole, the support rod 53 passes through the hole and is fixed by a positioning nut. The support rod 53 is 180 mm long and has a caliber of 20 mm. The up and down adjustment of the support rod 53 can be realized by the up and down adjustment of the L-shaped connecting plate. The support rod 23 is provided with a connecting buckle 54 at the top. The connecting buckle 54 is connected to the support rod 53 by a slip nut 52 and can be rotated up and down. The connecting buckle 54 is used to connect the screen and the slip bolt, so that the screen and the slip bolt are integrated with the main frame of the vibrating screen to transmit vibration energy.

[0075] When we use the vibrating screen to screen materials, we will find that different materials and different screening requirements are needed to ensure the optimization of the screening effect. We need to adjust the inclination angle of the screen to different angles. In actual work, we can adjust the horizontal height of the four corners of the adjustable screen 3 by adjusting the up and down position of the L-shaped connecting plate 51 in the sliding groove truss 10, so that the horizontal height difference of the longitudinal two sides of the adjustable screen 3 appears, and then the inclination angle of the adjustable screen 3 is formed. At the same time, the connecting buckle 54 connected to the adjustable screen 3 rotates up and down to form an angle consistent with the adjustable screen 3. By manually adjusting the horizontal height of the four corners of the screen 3, the screen can form an inclination angle of 10°-20°.

[0076] The embodiment provides a disc spring vibrating screen with adjustable inclination angle. The screen is connected to the main body of the screen box by using a slip bolt and a sliding groove. The displacement adjustment of the screen in the vertical direction is realized by using the sliding groove and the bolt fixation. The height adjustment range is the entire height of the screen box. The sliding groove and the slip bolt are used together to realize the large-angle adjustment of the screen. The inclination angle adjustment range of the screen is 0-60°. The large-range angle adjustment of the entire screen is realized, and the best screening process inclination angle requirement of the material particles for the entire screen is met.

[0077] Embodiment six. See Figure 4 The embodiment is used to illustrate the adjustable inclination angle screen 3 in the disc spring vibrating screen with adjustable inclination angle described in embodiment four. The adjustable inclination angle screen 3 includes at least two screen main body frames 30 and a special angle adjustment chain 31.

[0078] The two screen main body frames 30 are connected by the special angle adjustment chain 31.

[0079] In actual application, the embodiment is used as Figure 4The screen is a manganese steel screen steel plate punched screen, which bears the materials and vibrates under the driving of the main frame of the vibrating screen to screen the materials. The screen of the vibrating screen is designed by splicing multiple three-section screens, and a special hinge 31 is used to connect the main frame 30 of each screen. The angle between each screen can be adjusted, and the angle adjustment range is 0-30°. The angle of different positions of a screen can be adjusted, which meets the needs of the best screening process angle of the material particles at different positions.

[0080] The screen of the existing vibrating screen is an integral screen, which is integrally formed and fixed at four corners by bolts, and the angle of the screen is consistent with the angle of the screen box of the vibrating screen. Therefore, the angle of the screen is fixed. However, according to the analysis of the movement of the materials on the screen, it is found that the best screening process angle of the material particles in different areas of the screen changes constantly during the screening process. The angle of the screen of the existing vibrating screen cannot be adjusted, which causes all the material particles to be screened at the same angle, which reduces the screening efficiency and quality of the materials. The present embodiment provides a disc spring vibrating screen with adjustable angle, which adopts a splicing design of multiple screens, and each screen is connected by a special hinge. The angle between each screen can be adjusted, and the angle adjustment range of each screen is 0-15°. The angle of different positions in a screen can be accurately adjusted, which meets the needs of the best screening process angle of the material particles at different positions.

[0081] Embodiment seven. Referring to Figure 5 The present embodiment is an example of the drive device 4 of the disc spring vibrating screen with adjustable angle according to the fourth embodiment. The drive device 4 includes a motor 40, a coupling 42, a transmission shaft 43, an eccentric block 45, a rolling bearing 44, and a bearing seat 46.

[0082] The motor shaft 41 of the motor 40 is connected to the transmission shaft 43 through the coupling 42.

[0083] The eccentric block 43 is fixed on the transmission shaft 42.

[0084] The transmission shaft 42 is fixed in the bearing seat 45 through the rolling bearing 44.

[0085] In actual application, the present embodiment is Figure 5As shown, the motor 40 generates a rotating magnetic field by energizing a coil and acts on the rotor to form a magnetic electric power rotating torque, providing rotational power. In application, a Siemens servo motor 1FK7083-2AF71-1CH1 of model 1FK7083-2AF / AC71-1RG01 / RH0 / 1 is used. A shaft coupling 42 is provided on the right side of the motor 40, and the motor shaft 41 of the motor 40 is connected to a transmission shaft 43 through the shaft coupling 42, for transmitting the rotational energy of the motor, realizing the synchronous rotation of the driving shaft and the transmission shaft. In application, the shaft coupling is implemented by using a Xingda CLG double diaphragm elastic coupling with an outer diameter of 40 long 35 holes 12. The transmission shaft 43 passes through a ball bearing 44 and is supported by the ball bearing and the outer support point bearing seat. It is used to change the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing the friction loss. In application, the rolling bearing 44 is implemented by using a BMD stainless steel bearing S6318-2Z / P5 with an inner diameter of 40 mm. The ball bearing is installed in the bearing seat to support the bearing, fix the outer ring of the bearing, and only allow the inner ring to rotate, the outer ring remains stationary, always consistent with the direction of transmission, and keeps balance, and can reduce the pollution of the bearing, ensure the friction coefficient of the bearing, and reduce the friction loss. In application, the bearing seat 45 is implemented by using an SD644 high-speed high-precision imported quality bearing seat bearing. An eccentric block is installed on the transmission shaft between the two rolling bearings, which is a eccentric block, and its function is that when the transmission shaft rotates, the eccentric block rotates with it, generates an inertial excitation force, drives the main frame and screen of the vibrating screen to vibrate, and provides power for screening.

[0086] When the vibrating screen is working, the motor shaft 41 rotates at high speed under the action of the motor 40, drives the transmission shaft 43 to rotate at high speed through the connection of the shaft coupling 42, and makes the eccentric block 45 connected to the transmission shaft 43 rotate at high speed, thereby generating an excitation force. The excitation force is transmitted to the vibrating screen prototype frame 1 through the transmission shaft 43, the ball bearing 44 and the bearing seat 45, and the vibrating screen prototype frame 1 starts to do periodic reciprocating motion under the support of the disc spring elastic support assembly 2, thereby driving other components connected thereto to vibrate, providing power for the material particles, and completing the screening work.
