Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen with easy-to-assemble and disassemble screening components. Background Art

[0002] Vibrating screens are widely used in industrial production, primarily for screening and grading materials. They are widely used in industries such as coal, electricity, metallurgy, building materials, and chemicals. Their primary operating principle is to utilize the reciprocating vibrations generated by the vibrator's excitation to cause the material to be thrown onto the screen and move along a specific trajectory, thereby achieving the purpose of screening.

[0003] A vibrating screen usually consists of a screen and a vibrator. The coarseness of the screen is expressed in mesh, and screens of different coarseness can meet different screening needs. The vibrator screen frame vibrates. When the material flows onto the screen surface, the coarser solid particles will remain on the screen surface and be discharged from one end along the slope, while the finer solid particles and mud liquid flow through the screen holes to the lower layer. The coarseness of the screen is divided into different meshes, and different screening requires the replacement of different screens. Therefore, the screen needs to be replaced as needed during the screening process. During the use of traditional vibrating screens, the disassembly and installation of screening components is cumbersome and time-consuming. Therefore, a vibrating screen that is easy to disassemble and assemble the screening component is proposed, which is convenient for replacing the screen while improving the screening efficiency and stability.

[0023] See also Figure 1-3In this embodiment, a vibrating screen with easy disassembly and assembly of screening components includes a base 1, a screening component 2 movably connected to the top of the base 1, a fixing component 3 arranged inside the screening component 2, a vibrating component 4 arranged on the top of the base 1, and a supporting component 5 arranged on the outside of the base 1.

[0024] In this embodiment, the screening assembly 2 includes a screening box 21 movably connected to the top of the base 1, a positioning groove 22 opened on the inner wall of the screening box 21, a left fixed frame 23 movably connected inside the positioning groove 22, a through-hole slot 24 opened on the side wall of the screening box 21, a right fixed frame 25 movably connected inside the through-hole slot 24, and a screening net 26 movably connected inside the left fixed frame 23.

[0025] The left fixing frame 23 is supported by the positioning slot 22, and the right fixing frame 25 is supported by the through-slot 24. The left fixing frame 23 and the right fixing frame 25 fix and limit the two sides of the screening net 26, so that the screening net 26 can be smoothly fixedly installed inside the screening box 21.

[0026] In this embodiment, T-shaped slots are provided inside the left fixing frame 23 and the right fixing frame 25 to cooperate with and limit the screening net 26. T-shaped plates are fixedly installed at both ends of the screening net 26. The T-shaped plates on the left and right sides of the screening net 26 are longitudinally embedded in the T-shaped slots of the left fixing frame 23 and the right fixing frame 25 respectively and are slidably connected to the left fixing frame 23 and the right fixing frame 25.

[0027] By arranging T-shaped plates at both ends of the screening net 26 and embedding them into the T-shaped slots inside the left fixing frame 23 and the right fixing frame 25 , the left fixing frame 23 and the right fixing frame 25 can respectively fix the two ends of the screening net 26 .

[0028] It should be noted that a support frame is provided on the outside of the screening net 26 to prevent the surrounding of the screening net 26 from deformation.

[0029] In this embodiment, the fixing assembly 3 includes a positioning groove 31 opened on the right side wall of the screening box 21, a positioning wedge 32 slidably connected to the inside of the positioning groove 31, and an arc-shaped positioning wedge 33 movably connected to the bottom of the left fixing frame 23 and the right fixing frame 25.

[0030] The right fixing frame 25 is fixed by providing a positioning groove 31 and cooperating with the positioning wedge 32 , and the arc-shaped positioning wedge 33 is responsible for fixing the two ends of the screening net 26 inside the left fixing frame 23 and the right fixing frame 25 respectively.

[0031] In this embodiment, a guide plate 27 is fixedly installed on the inner bottom wall of the screening box 21, and discharge slots 28 are provided on both side walls of the screening box 21. The left fixing frame 23 is embedded in the interior of the positioning slot 22 and is slidably connected to the inner side wall of the positioning slot 22. The right fixing frame 25 is embedded in the interior of the through-slot 24 and is slidably connected to the inner side wall of the through-slot 24. A through hole is provided in the interior of the right fixing frame 25 for cooperating with the positioning wedge 32, and the positioning wedge 32 passes through the through hole and is slidably connected to the right fixing frame 25.

[0032] By setting the guide plate 27, the screened material is guided to the outlet, and the left fixing frame 23 is embedded in the positioning slot 22 so that the left side of the screening net 26 is fixed at the specified position of the screening box 21. The right fixing frame 25 is embedded in the through-slot 24 so that the right end of the screening net 26 is fixed at the specified position of the screening box 21. The positioning wedge 32 is inserted into the positioning slot 31 and the right fixing frame 25 at the same time, so that the right fixing frame 25 is fixed inside the through-slot 24, thereby achieving the fixation of the screening net 26.

[0033] In this embodiment, a buckle is provided on the side of the arc-shaped locking wedge 33. The arc-shaped locking wedge 33 is embedded in the T-slot inside the left fixing frame 23 and the right fixing frame 25 through the buckle and is fixed to the left fixing frame 23 and the right fixing frame 25 respectively. The arc-shaped locking wedge 33 at the bottom of the left fixing frame 23 and the right fixing frame 25 is slidably connected to the inner side walls of the locking slot 22 and the through-slot 24 respectively.

[0034] By setting the arc-shaped locking wedge 33 to be embedded in the left fixing frame 23 and the right fixing frame 25 through the buckle, the arc-shaped locking wedge 33 can fix the screening net 26 embedded in the left fixing frame 23 and the right fixing frame 25. At the same time, the arc-shaped locking wedge 33 is embedded in the locking groove 22 and the through-slot 24 to prevent the arc-shaped locking wedge 33 from falling from the bottom of the left fixing frame 23 and the right fixing frame 25 during vibration, thereby further ensuring the stability of the screening net 26 in the left fixing frame 23 and the right fixing frame 25.

[0035] In this embodiment, the vibration assembly 4 includes a vibration motor 42 fixedly mounted on a support plate 41, fixedly mounted on the side of the support plate 41, a rotating seat 43 rotatably connected to the side of the screening box 21, and a vibration ring 44 fixedly mounted on the side of the rotating axis of the rotating seat 43.

[0036] The vibration motor 42 is fixed by the support plate 41 , and the rotating seat 43 allows the vibration ring 44 to rotate to reduce internal friction loss, while transmitting the vibration of the vibration ring 44 to the screening box 21 .

[0037] It should be noted that the rotation of the rotating base 43 is damped, which prevents the vibration ring 44 from rotating synchronously with the vibration shaft 45 .

[0038] In this embodiment, a through hole is opened inside the support plate 41, and the output shaft of the vibration motor 42 passes through the through hole horizontally. A vibration shaft 45 is fixedly installed on the outside of the output shaft of the vibration motor 42, and a feed rack 46 is fixedly installed on the top of the support plate 41.

[0039] While the vibration motor 42 is fixed by the support plate 41, a perforation is provided to cooperate with the vibration motor 42 for power output, and the feed rack 46 smoothly guides the material into the interior of the screening box 21 for screening.

[0040] In this embodiment, a plurality of evenly distributed vibration bumps are provided on the outer side of the vibration shaft 45 . The vibration shaft 45 is laterally embedded in the interior of the vibration ring 44 , and the inner side wall of the vibration ring 44 is provided with vibration teeth used in conjunction with the vibration shaft 45 .

[0041] By using the vibrating teeth inside the vibrating ring 44 in conjunction with the vibrating protrusions of the vibrating shaft 45, the vibration motor 42 drives the vibrating shaft 45 to continuously hit the vibrating ring 44 to generate vibration. The vibration of the vibrating ring 44 drives the rotating seat 43 to drive the screening box 21 to vibrate, so that the vibrating screen can produce an efficient vibration effect when working.

[0042] In this embodiment, the support assembly 5 includes several supporting feet 51 fixedly installed on the side of the base 1, several anti-slip rubber pads 52 fixedly installed on the bottom of the supporting feet 51, several supporting springs 53 fixedly installed on the top of the base 1, and a damper 54 fixedly installed on the bottom of the supporting spring 53. The tops of the supporting springs 53 and the dampers 54 are fixedly installed on the bottom of the screening box 21.

[0043] The support feet 51 and the anti-slip rubber pads 52 ensure the stability and safety of the vibrating screen in complex terrain conditions. The support springs 53 and the damper 54 enable the screening box 21 to quickly return to its initial position after vibration.

[0044] The working principle of the above embodiment is:

[0045] By starting the vibration motor 42, the output shaft of the vibration motor 42 rotates and drives the protrusion on the outside of the vibration shaft 45 to continuously hit the vibration teeth inside the vibration ring 44, thereby driving the vibration ring 44 to continuously vibrate. The vibration of the vibration ring 44 drives the rotating seat 43 to drive the vibration of the screening box 21. The vibration of the screening box 21 drives the left fixing frame 23 inside the positioning slot 22 and the right fixing frame 25 inside the through slot 24 to vibrate, thereby driving the screening net 26 to vibrate and screen the material above. At the same time, the support spring 53 and the damper 54 at the bottom of the screening box 21 enable the screening box 21 to quickly return to its initial position after vibration.

[0046] In addition, by pulling out the positioning wedge 32 inside the positioning slot 31, the right fixing frame 25, the screening mesh 26 and the left fixing frame 23 can be pulled out from the inside of the screening box 21 along the through slot 24. Then, the arc-shaped positioning wedge 33 at the bottom of the left fixing frame 23 and the right fixing frame 25 is removed, and the screening mesh 26 can be taken out and replaced as a whole from the inside of the left fixing frame 23 and the right fixing frame 25, thereby solving the problem that the disassembly and installation of the screening components of the traditional vibrating screen during use is cumbersome and time-consuming.
