Detailed Implementation

The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0055] Example 1:

[0056] A banana vibrating screen includes: a screen body 1, a vibrator 2, an intermediate shaft 3, a drive shaft 4, a motor 5, a belt drive 6, and a secondary shaft pair 7. The vibrator 2 is mounted on the screen body 1, the intermediate shaft 3 is inserted into the inner side of the vibrator 2, the drive shaft 4 is inserted into the vibrator 2, the secondary shaft pair 7 is inserted into the vibrator 2, the belt drive 6 is mounted on the motor 5 and the secondary shaft pair 7, and a screening structure is installed on the screen body 1.

[0057] The screen body 1 includes: a pair of side plates, several crossbeams, several excitation beams, several lifting beams, and a back plate; the pair of side plates are respectively installed on both sides of the several crossbeams and several excitation beams, the several lifting beams are installed on the pair of side plates, and the back plate is installed on the pair of side plates; each component is made of high-quality structural steel with precision manufacturing; the crossbeams, excitation beams, and lifting beams are all heat-treated after welding and machined using advanced CNC machine tools; then, high-quality ring groove rivets are selected, and the screen body 1 is riveted using advanced clean sealing assembly technology; the side plates are seamless; the crossbeams and excitation beams have large section moduli and high rigidity; the surface of the crossbeams is coated with wear-resistant grease; the surface treatment of the screen body 1 reaches Sa2.5 level and is then sprayed with polyester protective paint; each process of manufacturing and assembling the screen body 1 undergoes strict inspection and control; the structure of the screen body 1 is optimized and lightweight; the screen body 1 can avoid cracking and wear of various components under high load and high frequency vibration working conditions, and has higher fatigue resistance, reliability, and service life;

[0058] Among them, the vibrator 2 adopts the latest special vibration bearing developed by SKF in Germany. The gearbox body has high machining precision, light structure, good sealing, fast heat dissipation, no oil leakage, low noise, convenient maintenance, and is durable and reliable. The swing block is equipped with multiple plug filling methods to meet different vibration indices and usage requirements for large variable eccentric torque or excitation force. Magnetic oil plugs are used to adsorb iron filings in the gear lubricating oil in a timely manner to improve the quality of the grease. Splash lubrication is adopted, and high-grade lubricating oil from world-renowned brands is selected to greatly improve the machine's performance and lifespan. The vibrator 2 can work normally in temperatures ranging from -30℃ to +80℃.

[0059] Among them, intermediate shaft 3: an intermediate shaft 3 is used to connect the two vibrators 2 so that the left and right vibrators 2 can rotate synchronously. The two ends of the intermediate shaft 3 are connected to the swing blocks of the vibrator 2 by unique elastic rubber disc couplings. The intermediate shaft 3 is a rigid shaft, which is maintenance-free and requires no lubrication.

[0060] Among them, drive shaft 4 is a universal locomotive shaft that connects the statically fixed drive mechanism and the dynamic vibrating screen body, with a long service life and low maintenance.

[0061] Among them, motor 5: The drive mechanism adopts the latest type of motor 5, which has a large starting torque and fast acceleration, enabling the screening machine to quickly pass through the resonance zone. Motor 5 is installed on the guide rail seat to make the belt tensioning. Motor 5 has reliable performance, which can ensure the continuity of user production, with less downtime and more output.

[0062] Among them, belt drive 6: the drive mechanism adopts SPB belt drive 6 for speed regulation and deceleration, and transmits power. The guide rail seat screw tensioning motor 5 is used to adjust the belt tension, so that the belt is used reasonably and has a long service life.

[0063] Among them, the secondary shaft 7: The secondary shaft 7 of the drive mechanism consists of a secondary shaft, SKF bearings, a locking sleeve, a labyrinth seal and an open bearing housing. It is durable, reliable and easy to install and maintain.

[0064] In use, the screening structure includes: a plurality of buffer springs 8 and a pair of screen plates 9; the plurality of buffer springs 8 are evenly installed on the outer side of the screen body 1, and the pair of screen plates 9 are installed in parallel on the inner side of the screen body 1.

[0065] Among them, buffer spring 8: The vibrating screen body and the mounting base are isolated and buffered by steel spiral compression springs. Rubber pads are added to both ends of the spring to reduce the wear and friction noise between the spring and the steel spring seat plate. The spring stiffness is small, which reduces the dynamic load on the foundation. The vibration reduction efficiency is over 98%. The spring wire diameter is sufficient to make the spring more fatigue-resistant and less prone to breakage.

[0066] Among them, the screen plate 9 is a standard modulus polyurethane composite screen plate 9 with patent number ZL200620150160.5 produced by Tianjin Weide Mining Equipment Co., Ltd. The screen plate 9 system has internationally leading technology, large opening ratio, screen gap is not easy to block, high screening efficiency, high strength is not easy to deform, wear-resistant and long service life, easy to disassemble and assemble, and sufficient supply.

[0067] The working principle is as follows: The drive mechanism motor 5 is powered on and rotates. The speed is adjusted by the belt drive mechanism 6. The driving force is transmitted to the drive shaft 4 through the auxiliary shaft 7, which drives the vibrator 2 to operate and generate linear vibration force. The linear vibration force acts on the screen body 1 in a cyclic and continuous manner, causing the screen body 1 to vibrate on the buffer spring 8. At the same time, the buffer spring 8 reduces the dynamic load of the screen body 1 on the screen machine support foundation. The screen body 1 drives the screen surface to vibrate synchronously, and transmits the force to the feed material on the screen. The impact feed material is thrown up and forward on the screen surface, compacted and layered, and screened and graded according to the specified particle size. The feed material is continuously fed from the feed chute to the receiving plate and buffered. It is screened through the screen surface. The undersize material is discharged into the undersize chute, and the oversize material is discharged into the discharge chute.

[0068] The performance of this embodiment is primarily demonstrated by its equal-thickness screening principle. For example, it employs a 5-angle, 5-segment zigzag screen surface. The screen surface inclination angle decreases progressively from the feed end to the discharge end at 25°, 20°, 15°, 10°, and 5° respectively. Under the action of the excitation force, the material is continuously thrown forward on the screen surface towards the discharge end, forming a material flow. The larger the screen surface inclination angle, the faster the material flow speed. While the feed end receives more material, the larger the screen surface inclination angle also accelerates the material movement speed, causing the material layer to thin rapidly and quickly stratify, allowing easily screened particles to pass through. The screen processes the material group after a portion has already passed through the previous section, with each section and the discharge end processing it sequentially. The feed rate and flow velocity gradually decrease. Since the thickness of the material layer on the screen surface is proportional to the feed rate and flow velocity, the material layer thickness is essentially uniform across all sections of the screen surface from the feed end to the discharge end. This appropriate and reasonable distribution of the material layer facilitates screening and increases the opportunity for fine particles to contact the screen surface, thus improving throughput compared to ordinary screening methods.

[0069] This embodiment undergoes rigorous testing and continuous 24-hour trial operation in the factory. A high-end FFT professional analyzer imported from Germany is used for frequency response and dynamic analysis to ensure reliable operation and high product quality. Its operating system is S1, guaranteeing stable continuous operation for 24 hours with low noise (below 75 decibels) and smooth operation. Improvements have been made based on long-term production practice and finite element stress analysis. The design and manufacturing comply with GB mechanical design standards, IEC international electrical standards, JB / T9022-1999 [Vibrating Screen Design Specification], JB / T5496-2004 [General Technical Conditions for Vibrating Screen Manufacturing], and relevant coal preparation machinery industry standards.

[0070] Example 2:

[0071] In use, the screening structure includes: a plurality of buffer springs 8 and a pair of screen plates 9; the plurality of buffer springs 8 are evenly installed on the outer side of the screen body 1, and the pair of screen plates 9 are installed in parallel on the inner side of the screen body 1.

[0072] The working principle of this embodiment is as follows: the drive mechanism motor 5 is powered on and rotates, and the speed is adjusted by the belt transmission mechanism 6. The driving force is transmitted to the drive shaft 4 through the auxiliary shaft 7 and drives the vibrator 2 to operate and generate linear vibration force. The linear vibration force acts on the screen body 1 in a continuous cycle, causing the screen body 1 to vibrate on the buffer spring 8. At the same time, the buffer spring 8 reduces the dynamic load of the screen body 1 on the screen machine support foundation. The screen body 1 drives the screen surface to vibrate synchronously, and transmits the force to the feed material on the screen. The impact feed material is thrown up and forward on the screen surface, compacted and layered, and screened and graded according to the specified particle size. The feed material is continuously fed from the feed chute to the receiving plate and buffered. It is screened through the double-layer screen surface. The undersize material is discharged into the undersize chute, and the oversize material is discharged into the discharge chute.

[0073] The high efficiency of this embodiment is mainly reflected in the principle of equal thickness screening. It adopts a multi-angle, multi-segment zigzag screen surface, with the screen surface inclination angle decreasing gradually from the feed end to the discharge end. Under the action of excitation force, the material is continuously thrown forward on the screen surface towards the discharge end to form a material flow. The larger the screen surface inclination angle, the faster the material flow speed. The feed end has more material, but the large screen surface inclination angle makes the material movement speed faster, the material layer becomes thinner rapidly, and it quickly stratifies, allowing easy-to-screen particles to pass through the screen. The screen surfaces in the middle sections and at the discharge end process the material group after a portion of the material has passed through the previous section. The feed gradually decreases, and the inclination angle and flow velocity gradually decrease. Since the thickness of the material layer on the screen surface is proportional to the feed rate and the material flow velocity, the material layer thickness is basically equal in each section of the screen surface from the feed end to the discharge end. The material layer thickness is appropriately and reasonably distributed on the screen surface, which facilitates screening and increases the opportunity for fine particles to come into contact with the screen surface, making it easier to pass through the screen. Therefore, compared with ordinary screening methods, equal thickness screening can significantly improve the screen's throughput and screening efficiency.

[0074] This embodiment undergoes rigorous testing and continuous 24-hour trial operation in the factory. A high-end FFT professional analyzer imported from Germany is used for frequency response and dynamic analysis to ensure reliable operation and high product quality. Its operating system is S1, guaranteeing stable continuous operation for 24 hours with low noise (below 75 decibels) and smooth operation. Improvements have been made based on long-term production practice and finite element stress analysis. The design and manufacturing comply with GB mechanical design standards, IEC international electrical standards, JB / T9022-1999 [Vibrating Screen Design Specification], JB / T5496-2004 [General Technical Conditions for Vibrating Screen Manufacturing], and relevant coal preparation machinery industry standards.

[0075] Example 3:

[0076] In use, the screening structure includes: several buffer springs 8 and three screen plates 9; the several buffer springs 8 are evenly installed on the outside of the screen body 1, and the three screen plates 9 are installed in parallel on the inside of the screen body 1.

[0077] The working principle of this embodiment is as follows: the drive mechanism motor 5 is powered on and rotates, and the speed is adjusted by the belt transmission mechanism 6. The driving force is transmitted to the drive shaft 4 through the auxiliary shaft 7, which drives the vibrator 2 to operate and generate linear vibration force. The linear vibration force acts on the screen body 1 in a continuous cycle, causing the screen body 1 to vibrate on the buffer spring 8. At the same time, the buffer spring 8 reduces the dynamic load of the screen body 1 on the screen machine support foundation. The screen body 1 drives the screen surface to vibrate synchronously, and transmits the force to the feed material on the screen. The impact feed material is thrown up and forward on the screen surface, compacted and layered, and screened and graded according to the specified particle size. The feed material is continuously fed from the feed chute to the receiving plate and buffered. It is screened through three layers of screen surface. The undersize material is discharged into the undersize chute, and the oversize material is discharged into the discharge chute.

[0078] Example 4:

[0079] In use, the crossbeam includes a vibrating screen circular tube crossbeam A1, a vibrating screen support bracket A2, a vibrating screen washer A3, and a vibrating screen rivet A4. The vibrating screen support bracket A2 is installed above the vibrating screen circular tube crossbeam A1, the vibrating screen washer A3 is installed on the upper wall of the vibrating screen support bracket A2, and the vibrating screen rivet A4 fixes the vibrating screen support bracket A2, the vibrating screen washer A3, and the vibrating screen circular tube crossbeam A1 together. A protective structure is provided above the vibrating screen circular tube crossbeam A1.

[0080] It should be noted that the crossbeam adopts the circular tube crossbeam A1 of the vibrating screen. The circular tube design facilitates material passage and prevents the accumulation of sticky materials. The circular tube has no weld seams and is fixed by riveting with vibrating screen rivets 2. The structure has high rigidity, high strength, reasonable and balanced stress distribution, high safety factor, and compact structure. The mating surfaces of the vibrating screen circular tube crossbeam A1 are all precision machined by CNC machine tools before assembly, effectively ensuring the overall assembly quality of the screen machine. The vibrating screen support bracket A2 adopts a casting structure design and undergoes annealing treatment after casting. The vibrating screen rivets A4 are high-quality vibrating screen rivets, and the screen body is riveted using an advanced clean and sealed assembly process. This can prevent cracking and wear under high load and high frequency vibration working conditions, and has higher fatigue resistance, reliability, and service life.

[0081] The protective structure includes: a vibrating screen connecting block A5, a vibrating screen spring A6, a vibrating screen locking block A7, and a protective plate A8;

[0082] Vibrating screen connecting blocks A5 are fixedly installed above vibrating screen round tube beam A1. Vibrating screen springs A6 are fixedly installed in the grooves inside vibrating screen connecting blocks A5. Vibrating screen locking blocks A7 are fixedly installed on vibrating screen springs A6. Protective plates A8 are locked onto vibrating screen support brackets A2 through elongated holes. Protective plates A8 have locking holes at their bottom ends, and vibrating screen locking blocks A7 are locked onto the locking holes.

[0083] It should be noted that the protective plate A8 can provide some protection for the vibrating screen support bracket A2, preventing it from being deformed due to excessive force. Furthermore, the vibrating screen spring A6 allows the vibrating screen locking block A7 to be easily locked into the locking hole at the bottom of the protective plate A8, making the installation of the protective plate A8 and the vibrating screen connecting block A5 more convenient and facilitating the installation and fixation of the protective plate A8.

[0090] In use, the excitation beam includes: excitation beam top plate C1, excitation beam bottom plate C2, a pair of excitation beam side plates C3, a pair of excitation beam flanges C4, two pairs of excitation beam cylindrical fixed shafts C7, four pairs of excitation beam damping spring columns C8, two pairs of excitation beam damping springs C9, four pairs of excitation beam connecting columns C10, two pairs of excitation beam scissor type brackets C11, and four pairs of excitation beam scissor type auxiliary springs C12;

[0091] Specifically, a pair of excitation beam side plates C3 are horizontally and parallelly welded to a pair of excitation beam flanges C4. The excitation beam top plate C1 and the excitation beam bottom plate C2 are also welded to the pair of excitation beam flanges C4, with the top plate C1 and bottom plate C2 connected to the pair of excitation beam side plates C3 at right angles. Two pairs of excitation beam cylindrical fixed shafts C7 are respectively inserted into a pair of excitation beam side plates C3. Four pairs of excitation beam damping spring columns C8 are respectively installed on two pairs of excitation beam cylindrical fixed shafts C7. 8. The other end is respectively installed on the top plate C1 of the excitation beam. The two pairs of excitation beam damping springs C9 are respectively fitted on the two pairs of excitation beam cylindrical fixed shafts C7. The four pairs of excitation beam connecting columns C10 are respectively installed on the two pairs of excitation beam damping springs C9, and the other end of the four pairs of excitation beam connecting columns C10 is respectively installed on the top plate C1 of the excitation beam. The two pairs of excitation beam scissor brackets C11 are installed on the two pairs of excitation beam cylindrical fixed shafts C7. The four pairs of excitation beam scissor auxiliary springs C12 are respectively installed on the two pairs of excitation beam scissor brackets C11.

[0092] In use, a box structure is assembled from one excitation beam top plate C1, one excitation beam bottom plate C2, two excitation beam side plates C3, and two excitation beam flanges C4. Two excitation beam double plates C6 are fixed on each side of the excitation beam top plate C1. Excitation beam stiffening plates C5 are welded to the outer sides of the box excitation beam side plates C3 at corresponding positions with the excitation beam double plates C6 and at the middle position of the box. All major welds are fully fused and subjected to first-level UT flaw detection and magnetic particle flaw detection. Heat treatment is then performed to eliminate welding stress. The structure has high rigidity, high strength, reasonable and balanced stress distribution, and a large safety factor. The excitation beam bottom plate C2 adopts a beveled edge design to prevent material accumulation and extend service life. The mating surfaces of the excitation beams are precision machined using CNC machine tools before assembly, effectively ensuring the overall assembly quality of the screening machine. High-quality bolts are selected, and advanced clean sealing assembly technology is used to tighten the screen body 1 to the specified tightening torque. It can avoid cracking and wear under high-load, high-frequency vibration conditions, exhibiting higher fatigue resistance, reliability, and service life. Based on long-term production practice and improvements made through finite element stress analysis, the design and manufacturing conform to GB mechanical design standards, JB / T9022-1999 [Vibrating Screen Design Specification], JB / T5496-2004 [General Technical Conditions for Vibrating Screen Manufacturing], and relevant coal preparation machinery industry standards. When the top plate C1 of the excitation beam and a pair of excitation beam side plates C3 are subjected to external forces, the external forces are transmitted to the four pairs of excitation beam damping spring columns C8 and the four pairs of excitation beam connecting columns C10, and then the external forces are transmitted to the two pairs of... The vibration damping spring C9, made of elastic material, deforms under external force and returns to its original shape after the external force is removed. It converts the external force into the elastic deformation of the four pairs of vibration damping spring columns C8 and the two pairs of vibration damping springs C9. The external force is consumed by the elastic deformation. After the external force is consumed, the external force absorbed by the deformation of the four pairs of vibration damping spring columns C8 and the two pairs of vibration damping springs C9 is released through elastic deformation, thus preventing the vibration top plate C1 and the pair of vibration side plates C3 from deforming under external force.
