Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening technology, specifically a balanced elliptical vibrating screen. Background Technology
[0002] Screening technology has evolved gradually with the development of industrial production. Early screening mainly relied on simple manual screens, such as hand sieves, which were inefficient and had poor screening accuracy. With the acceleration of industrialization, mechanical vibrating screens began to appear. The earliest vibrating screens were mostly simple linear vibrating screens and circular vibrating screens. Linear vibrating screens had a strong material conveying capacity, but the screening efficiency was not ideal in some cases. Circular vibrating screens had high screening efficiency, but the conveying capacity was relatively weak.
[0003] Over time, fine particles in the material will gradually clog the screen mesh. During the screening of fine sand, sticky components such as mud in the sand may adhere to the screen mesh walls, preventing fine sand particles from passing through normally. Existing technologies that use mechanically driven brush plates to clean the screen have certain drawbacks. If the brush bristles are not of suitable hardness and coarseness, they will not be effective in cleaning blockages in some small mesh openings. Coarser bristles may not be able to penetrate the small openings, while bristles that are not hard enough will be unable to remove stubborn blockages. Therefore, we propose a balanced elliptical vibrating screen. Utility Model Content
[0004] The purpose of this invention is to provide a balanced elliptical vibrating screen to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a balanced elliptical vibrating screen, comprising:
[0006] The base plate, the supporting legs at the bottom of the base plate, and the sieve box at the top of the base plate;
[0007] A cleaning assembly is placed on top of a screen box. The cleaning assembly includes a rotating shaft rotatably connected to the top of the screen box, a torsion spring mounted on the rotating shaft, a fixed rod rotatably connected to the top of the torsion spring, a first connecting rope connected to the fixed rod near the top, a bouncing ball fixedly connected to the end of the first connecting rope away from the fixed rod, the bouncing ball being located inside the screen box, and an opening provided on the top of the screen box near the first connecting rope, the first connecting rope sliding within the opening.
[0008] A power assembly is located on the top of the screen box. The power assembly includes a fixed shaft rotatably connected to the top of the screen box. A take-up roller is provided on the top of the fixed shaft. A second connecting rope is sleeved on the take-up roller. The end of the second connecting rope away from the take-up roller is connected to a fixed rod. A second housing is provided on the top of the take-up roller. A first motor is provided inside the second housing. The take-up roller is fixedly connected to the output end of the first motor.
[0009] Furthermore, a screening assembly is provided inside the screen box. The screening assembly includes a vibrator body, a first housing is provided on the vibrator body, a second motor is provided inside the first housing, an eccentric shaft is provided inside the vibrator body, and a screen is provided inside the screen box, with the screen connected to the eccentric shaft.
[0010] The above technical solution is adopted: by setting up a screening component, the eccentric shaft is rotated by a second motor to generate an unbalanced force, thereby driving the screen to make elliptical motion.
[0011] Furthermore, the screen box has an inclination angle of 30 degrees, and a support rod is fixedly connected between the screen box and the base plate.
[0012] The above technical solution involves setting an inclined screen box to facilitate the discharge of the screened material due to gravity.
[0013] Furthermore, a feed pipe is provided at the top of the screen box, and a discharge assembly is provided on the side of the screen box away from the feed pipe. The discharge assembly includes a slide rail, and a discharge port is provided on the side of the screen box near the slide rail.
[0014] The above technical solution facilitates material feeding by setting up a feed pipe and facilitates material discharge by setting up a discharge port.
[0015] Furthermore, a slider is slidably connected to the slide rail, and a baffle is connected to the slider. The size of the baffle is the same as that of the discharge port.
[0016] The above technical solution involves setting up baffles to block materials that have not yet finished screening. Once the screening is complete, opening the baffles allows the materials to be discharged through the outlet.
[0017] Furthermore, a shock-absorbing component is provided between the screen box and the bottom plate. The shock-absorbing component includes a spring, the two ends of which are fixedly connected to the bottom of the screen box and the top of the bottom plate, respectively. The spring is equipped with damping.
[0018] The above technical solution involves installing shock-absorbing components between the screen box and the base plate to support the screen box, buffer vibrations, and reduce the impact on the foundation.
[0019] Furthermore, a collection box is provided on the top side of the screen box near the discharge port.
[0020] The above technical solution involves setting up a collection bin to collect the discharged material, facilitating subsequent processing.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by incorporating a cleaning component, the bouncy ball, being relatively soft, effectively removes blockages when impacting the screen without causing significant scratches or wear, thus extending the screen's lifespan and reducing equipment maintenance costs. This solves the problem of fine particles in the material gradually clogging the screen mesh over time. During the screening of fine sand, sticky components such as mud may adhere to the screen mesh walls, preventing normally passable sand particles from passing through. Existing technologies using mechanically driven brush plates for screen cleaning have drawbacks. If the brush bristles' hardness and coarseness are unsuitable, they are ineffective at cleaning blockages in small mesh openings. Coarser bristles may not penetrate the small holes, while bristles with insufficient hardness may fail to remove stubborn blockages. Attached Figure Description

[0035] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] like Figures 1-4 As shown, this utility model provides a technical solution: a balanced elliptical vibrating screen, comprising:
[0037] The base plate 1, the support legs 2 at the bottom of the base plate 1, and the sieve box 3 at the top of the base plate 1;
[0038] Cleaning component 4 is placed on top of screen box 3. Cleaning component 4 includes a rotating shaft 41 rotatably connected to the top of screen box 3. A torsion spring 42 is provided on the rotating shaft 41. A fixed rod 43 is rotatably connected to the top of the torsion spring 42. A first connecting rope 44 is connected to the side of the fixed rod 43 near the top. A bouncing ball 45 is fixedly connected to the end of the first connecting rope 44 away from the fixed rod 43. The bouncing ball 45 is located inside screen box 3. An opening 46 is opened on the side of the top of screen box 3 near the first connecting rope 44. The first connecting rope 44 slides in the opening 46.
[0039] The power assembly 6 is located on the top of the screen box 3. The power assembly 6 includes a fixed shaft 61 rotatably connected to the top of the screen box 3. A take-up roller 62 is provided on the top of the fixed shaft 61. A second connecting rope 63 is sleeved on the take-up roller 62. The end of the second connecting rope 63 away from the take-up roller 62 is connected to the fixed rod 43. A second housing 64 is provided on the top of the take-up roller 62. A first motor is provided inside the second housing 64. The take-up roller 62 is fixedly connected to the output end of the first motor.
[0040] Specifically, when long-term screening causes residual material on the screen 53 to clog it, the first motor is turned on to drive the take-up roller 62 to rotate through the fixed shaft 61. The take-up roller 62 will drive the second connecting rope 63 to retract. The second connecting rope 63 will drive the fixed rod 43 to rotate through the set rotating shaft 41 and torsion spring 42. The fixed rod 43 will drive the first connecting rope 44 to slide and rise and fall in the opening 46, thereby causing the bouncing ball 45 in the screen box 3 to bounce on the screen 53, hit the surface of the screen 53, and shake off the blockage.
[0041] Furthermore, such as Figure 1 and Figure 3 As shown: The screen box 3 is equipped with a screening component 5, which includes a vibrator body 51, a first housing 52 on the vibrator body 51, a second motor inside the first housing 52, an eccentric shaft inside the vibrator body 51, and a screen 53 inside the screen box 3. The screen 53 is connected to the eccentric shaft. When the second motor is turned on, it drives the eccentric shaft to rotate, generating an unbalanced force, which drives the screen 53 to make an elliptical motion. The material on the screen 53 is thrown up by the upward force of the screen surface, and after moving forward a certain distance, it falls back onto the screen 53. This process is repeated to complete the screening.
[0042] The above solutions also have the problem that the screened material is inconvenient to discharge and collect, such as... Figure 1 and Figure 2 As shown: The screen box 3 is tilted at an angle of 30 degrees. A support rod 10 is fixedly connected between the screen box 3 and the bottom plate 1. A feed pipe 9 is provided on the top of the screen box 3. A discharge assembly 7 is provided on the side of the screen box 3 away from the feed pipe 9. The discharge assembly 7 includes a slide rail 71. A discharge port 74 is opened on the side of the screen box 3 near the slide rail 71. By setting the screen box 3 at an inclination, the screened material can be discharged from the discharge port 74 due to gravity.
[0043] The above solution also has the problem that the screen box 3 will vibrate during the screening process. Long-term vibration can lead to loosening of internal parts, such as... Figure 3 As shown: A shock-absorbing component 8 is provided between the screen box 3 and the base plate 1. The shock-absorbing component 8 includes a spring 81. The two ends of the spring 81 are fixedly connected to the bottom of the screen box 3 and the top of the base plate 1, respectively. A damper 82 is provided inside the spring 81. By setting the shock-absorbing component 8 and installing it between the screen box 3 and the base plate 1, it plays the role of supporting the screen box 3, buffering vibration and reducing the impact force on the foundation.
[0044] Furthermore, such as Figure 2As shown: A slider 72 is slidably connected to the slide rail 71, and a baffle 73 is connected to the slider 72. The size of the baffle 73 is the same as that of the discharge port 74. A collection box 75 is set on the top of the screen box 3 near the discharge port 74. By setting the baffle 73, it is convenient to block the material that has not been screened. When the material screening is completed, the baffle 73 can be opened to discharge the material through the discharge port 74 and then fall into the collection box 75 for collection.
[0045] The working principle of this utility model is as follows: First, the material is fed from the feed pipe 9 onto the screen 53 inside the screen box 3. Then, the second motor is turned on to drive the eccentric shaft to rotate, generating an unbalanced force, which drives the screen 53 to make an elliptical motion. The material on the screen 53 is thrown up by the upward force of the screen surface, and after moving forward a certain distance, it falls back onto the screen 53. This process is repeated to complete the screening. Due to the inclination angle of the screen box 3, the screened material slides towards the discharge port 74. Then, the baffle 73 is raised on the slide rail 71 by the slider 72, thereby opening the discharge port 74. The material then slides from the discharge port 74 into the collection box 75 for collection. During the screening process, the vibration generated by the spring 81 and the internal damper 82 is absorbed to reduce the impact on the screen box 3. When the residual material on the screen 53 causes blockage due to long-term screening, the first motor is turned on to drive the winding roller 62 to rotate through the fixed shaft 61. The winding roller 62 will drive the second connecting rope 63 to retract. The second connecting rope 63 will drive the fixed rod 43 to rotate through the set rotating shaft 41 and torsion spring 42. The fixed rod 43 will drive the first connecting rope 44 to slide and rise and fall in the opening 46, thereby causing the bouncing ball 45 in the screen box 3 to bounce on the screen 53 and hit the surface of the screen 53, shaking off the blockage.
[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced.
