Description

Technical Field

[0001] This utility model belongs to the field of high-frequency track vibrating screen technology, and in particular relates to a grading structure for a high-frequency track vibrating screen. Background Technology

[0002] High-frequency track vibrating screens use high-frequency vibration to screen materials, and different aperture screens are set in different sections of the screen to achieve the purpose of grading and screening. However, in the existing track vibrating screen, the screening effect of materials in different sections of the track vibrating screen cannot be independently adjusted during the screening process. Precise screening and feeding of materials during the screening process is relatively troublesome, and it is also relatively troublesome to change the grading effect later. Utility Model Content

[0003] The purpose of this invention is to provide a grading structure for a high-frequency track vibrating screen. The grading vibrating screen is used to grade and screen the materials that need to be screened. The vibration and screening effect of the grading vibrating screen at each position can be adjusted independently to achieve the best grading and screening effect. The grading vibrating screen can be disassembled and replaced to achieve the desired grading effect. This solves the problems of poor independent controllability of grading and screening at different positions and troublesome adjustment of screening effect in the later stage.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a grading structure for a high-frequency track vibrating screen, comprising a vibrating screen box, a grading vibrating screen, a high-frequency vibrating motor, and a support frame structure. The bottom of the vibrating screen box has multiple discharge square tubes spaced at equal intervals. A grading vibrating screen is installed in the vibrating screen box above each discharge square tube. The output end of the previous grading vibrating screen is located above the input end of the next grading vibrating screen. The grading vibrating screen is mounted on the inner wall of the vibrating screen box via two support rods. A high-frequency vibrating motor is installed on the outer wall of the vibrating screen box at the corresponding position of each grading vibrating screen. The vibration shaft of the high-frequency vibrating motor is connected to the support rod at the output end of the grading vibrating screen. The top of the vibrating screen box is covered with a top cover, and the top cover has a feeding port at the feeding position of the vibrating screen box. A material flow pipe is fitted around the bottom of each discharge square tube. A support frame structure is installed on the side wall of the vibrating screen box.

[0006] The present invention is further configured such that the grading vibrating screen includes a screen plate and side baffles. Side baffles are symmetrically arranged on both sides of the upper surface of the screen plate. The side of the side baffle near the input end of the screen plate is 20-30cm away from the input end. The side of the side baffle near the output end of the screen plate is flush with the output end. The side baffle has an inwardly tapered baffle at the inner side of the output end. Screen holes are evenly distributed in the middle section of the screen plate. Support rod through holes are provided at the bottom of the screen plate near both sides.

[0007] The present invention is further configured such that the screen holes on the upper screen plate of the grading vibrating screen gradually increase in size from the input end to the output end of the vibrating screen box.

[0008] The present invention is further configured such that the vibrating screen box is inclined downward from the input end to the output end, and all the screen plates of the grading vibrating screen are parallel to each other and parallel to the bottom of the vibrating screen box 1.

[0009] The present invention is further configured such that the support frame structure includes a rotating support rod and an angle adjustment assembly, the vibrating screen box has rotating support rods symmetrically installed on the two side walls near the output end, the top inner side of the rotating support rod is rotatably installed on the side wall of the vibrating screen box, the bottom end of the rotating support rod is fixed to the ground, and the angle adjustment assembly includes an adjusting hydraulic cylinder and a mounting column, the bottom end of the adjusting hydraulic cylinder is rotatably installed on the mounting column, and the top end is rotatably installed on the bottom of the input end of the vibrating screen box.

[0010] The present invention is further configured such that the screening material flow pipe includes a feeding pipe and a discharge pipe, wherein the input end of the feeding pipe is sleeved on the output end of the discharge square pipe, and the input end of the discharge pipe is sleeved on the output end of the feeding pipe.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model has multiple graded vibrating screens arranged in a stepped manner inside the vibrating screen box. When the material falls from the first graded vibrating screen, it slides down the graded vibrating screen. Due to the vibration of the graded vibrating screen, the falling speed of the material from the screen holes is accelerated, and at the same time, the material is vibrated to achieve the material flow and tumbling effect, thereby improving the screening efficiency. The material screened at each graded vibrating screen position will fall directly into the corresponding discharge square pipe, and be discharged from the corresponding screening material flow pipe and transported to a specific location, thus achieving a multi-stage screening effect.

[0013] 2. The vibration effect of each grading vibrating screen in this utility model can be independently controlled, which can realize the screening effect at each position. Moreover, the grading vibrating screen is easy to disassemble, and can be easily maintained and the screening grade can be changed later.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-4 This utility model relates to a grading structure for a high-frequency track vibrating screen, comprising a vibrating screen box 1, a grading vibrating screen 7, a high-frequency vibrating motor 3, and a support frame structure. The bottom of the vibrating screen box 1 is provided with multiple discharge square tubes 11 spaced at equal intervals. A grading vibrating screen 7 is installed in the vibrating screen box 1 above each discharge square tube 11. The output end of the previous grading vibrating screen 7 is located above the input end of the next grading vibrating screen 7. The grading vibrating screen 7 is mounted on the inner wall of the vibrating screen box 1 via two support rods. A high-frequency vibrating motor 3 is installed on the outer wall of the vibrating screen box 1 at the corresponding position of each grading vibrating screen 7. The vibration shaft of the high-frequency vibrating motor 3 is connected to the support rod at the output end of the grading vibrating screen 7. The top of the vibrating screen box 1 is covered with a top cover 2, and the top cover 2 has a feeding port at the feeding position of the vibrating screen box 1. A screening material flow pipe is fitted to the bottom of each discharge square tube 11. A support frame structure is installed on the side wall of the vibrating screen box 1.

[0024] A removable top cover 2 is installed on the top of the vibrating screen box 1 to reduce dust. There is only a feeding port at the feeding position. During feeding, the material falls concentrated above the input end of the first grading vibrating screen 7. As the material slides down from the grading vibrating screen 7, it passes through the screening holes, and the vibration effect causes the material to tumble. Fine particles sink faster and contact the screen holes 711, achieving the screening purpose more quickly. After screening by the previous grading vibrating screen 7, the unscreened material slides onto the next grading vibrating screen 7 for further screening. Each grading vibrating screen 7 has a different screening particle size. The screened material falls through the discharge square pipe 11 and is discharged to a designated location through the material flow pipe.

[0025] The grading vibrating screen 7 includes a screen plate 71 and side baffles 72. Side baffles 72 are symmetrically arranged on both sides of the upper surface of the screen plate 71. The side of the side baffle 72 near the input end of the screen plate 71 is 20-30cm away from the input end. The side of the side baffle 72 near the output end of the screen plate 71 is flush with the output end. The side baffle 72 has an inwardly tapered baffle 73 on the inner side of the output end. Screen holes 711 are evenly distributed in the middle section of the screen plate 71. Support rod through holes 74 are provided at the bottom of the screen plate 71 near both sides.

[0026] The side baffle 72 prevents material from flowing to both sides, ensuring that the material only flows at the screen hole 711 during the screening process. The non-perforated position above the screen hole 711 is below the non-perforated position at the output end of the previous screen plate 71. Since the non-perforated position requires the installation of support rods, and the screened material needs to be conveyed separately for separate discharge square tubes 11, the inward-curving baffle 73 narrows the material when it exits from the output end of the screen plate 71. As the material falls, it does not flow to the sides of the input end of the next screen plate 71, but instead enters the side baffle 72, improving material flow and preventing overflow.

[0027] The screen plate 71 of the graded vibrating screen 7 gradually increases in size from the input end to the output end of the vibrating screen box 1.

[0028] The process begins by screening small particles to achieve graded screening. Finally, the largest particles are uniformly conveyed out from the output end. A dedicated output channel or pipe (such as...) can be installed at the output end of vibrating screen box 1. Figure 1 and 2 The output pipe shown is inserted into the port of the output pipe at the output end of the screen plate 71 at the output end of the vibrating screen box 1.

[0029] The vibrating screen box 1 is inclined downward from the input end to the output end, and the screen plates 71 of all the grading vibrating screens 7 are parallel to each other and parallel to the bottom of the vibrating screen box 1.

[0030] The tilting of the vibrating screen box 1 enables the synchronous tilting of the grading vibrating screen 7. When tilted, the material can slide down automatically, and it is also easy to adjust the tilt of all the grading vibrating screens 7 synchronously.

[0031] The support frame structure includes a rotating support rod 5 and an angle adjustment assembly. The rotating support rod 5 is symmetrically installed on the two side walls near the output end of the vibrating screen box 1. The top inner side of the rotating support rod 5 is rotatably installed on the side wall of the vibrating screen box 1, and the bottom end of the rotating support rod 5 is fixed to the ground. The angle adjustment assembly includes an adjusting hydraulic cylinder 6 and a mounting column. The bottom end of the adjusting hydraulic cylinder 6 is rotatably installed on the mounting column, and the top end is rotatably installed on the bottom of the input end of the vibrating screen box 1.

[0032] Rotating the support rod 5 ensures that the front end of the vibrating screen box 1 rotates but the height remains unchanged, while adjusting the hydraulic cylinder 6 can appropriately adjust the bottom height of the vibrating screen box 1 to adjust the tilt of the vibrating screen box 1, thereby adjusting the speed at which the material slides down the screen plate 71.

[0033] The material flow pipe includes a feed pipe 4 and a discharge pipe 41. The input end of the feed pipe 4 is sleeved on the output end of the discharge square pipe 11, and the input end of the discharge pipe 41 is sleeved on the output end of the feed pipe 4.

[0034] The structures of feed pipe 4 and discharge pipe 41 are not limited to Figure 1 and 2 As shown, the structure and orientation can be designed as needed to discharge materials onto the conveyor track at a designated location. When the vibrating screen box 1 is tilted, the displacement distance of the discharge pipe 41 is small and does not affect the conveying of materials.
