Description

Technical Field

[0001] The utility model relates to the technical field of wet screening equipment, in particular to a feeding device for wet screening equipment. Background Technique

[0002] As an advanced solid particle screening and grading equipment, wet screening equipment plays a crucial role in industries such as mining, metallurgy, chemical engineering, and building materials. Compared with traditional dry screening equipment, wet screening equipment is gradually becoming the mainstream choice in the market due to its unique advantages. The wet screening equipment generates vibration force through a vibration motor to make the screen surface vibrate, and at the same time, combined with the action of a liquid medium, the material is efficiently screened and graded on the screen. During the screening process, the material is suspended in the liquid, and the particles are separated through the vibration of the screen and the impact of the liquid. This working method not only effectively reduces the friction between the particles and the screen, reduces the blockage phenomenon, but also significantly improves the screening efficiency. When using wet screening equipment, feeding is required. The feeding device of traditional wet screening equipment is inconvenient for quantitative conveying of materials, and the materials are prone to blockage during transportation, so there are certain drawbacks.

[0003] In summary, the utility model solves the existing problems by designing a feeding device for wet screening equipment. Content of the Utility Model

[0027] For the embodiments, please refer to Figures 1-7 , the present utility model provides a technical solution:

[0028] A feeding device for a wet screening device, comprising a belt conveyor 1. A first guide plate 2 is installed at the outer end of the belt conveyor 1. A support plate 3 is installed outside the belt conveyor 1 and below the first guide plate 2. Support columns 4 are installed at the four corners of the bottom of the support plate 3. A through groove 301 is opened at the center position of the top of the support plate 3. T-shaped grooves 302 are symmetrically opened on both sides of the through groove 301 at the top of the support plate 3. A vertical plate 5 is installed at one end of the wider side surface of the support plate 3. A control panel 6 is installed at the top of the vertical plate 5. A support frame 7 is installed below the through groove 301 at the bottom of the support plate 3. A driving motor 8 is installed at the top of the support frame 7. An elliptical block 9 is installed on the output shaft of the driving motor 8;

[0029] At one end of a shorter edge at the top of the support plate 3, a fixed plate 10 is installed. At both ends of the outer side of the fixed plate 10, reset springs 11 are symmetrically installed. At one end of the reset springs 11 away from the fixed plate 10 and on the top of the support plate 3, a feeding frame 12 is installed. At one end of the relatively wide inner side walls of the feeding frame 12, arc-shaped grooves 1201 are symmetrically opened. At the bottom of the feeding frame 12 and inside the through groove 301, a fixed block 13 is installed. At both ends of the bottom of the feeding frame 12 and inside the two T-shaped grooves 302, T-shaped sliders 14 are installed. At one end of the feeding frame 12 away from the reset spring 11 on the outside, a second guide plate 15 is installed. At the inner bottom of the feeding frame 12, an inclined plate 16 is installed. On the top of the inclined plate 16, a weighing platform 17 is installed. At one end of the two longer edges at the top of the feeding frame 12, limit blocks 18 are symmetrically installed. Inside the limit blocks 18, rotating shafts 19 are installed. Between the outer ends of the rotating shafts 19 and inside the feeding frame 12, a baffle 20 is installed. At the bottom edges of both ends of the outside of the baffle 20 and inside the arc-shaped groove 1201, cylindrical blocks 21 are installed. Above the second guide plate 15 on the outside of the feeding frame 12, a U-shaped frame 22 is installed. On the inner side wall of the U-shaped frame 22, an electric telescopic rod 23 is installed.

[0030] Specifically, referring to Figure 2 、 Figure 4 and Figure 6 , the elliptical block 9 is located inside the through groove 301, and the elliptical block 9 rotates and presses the fixed block 13 to move the feeding frame 12 on the top of the support plate 3, so as to ensure that the driving motor 8 drives the elliptical block 9 to rotate. The elliptical block 9 rotates and presses the fixed block 13 to move the feeding frame 12 on the top of the support plate 3 and presses the two reset springs 11. As the elliptical block 9 continuously rotates and presses the fixed block 13 in a cycle, the feeding frame 12 reciprocates on the top of the support plate 3 to generate vibration, which is convenient for feeding the materials on the weighing platform 17.

[0031] Furthermore, the outer side dimension of the T-shaped slider 14 matches the inner side wall dimension of the T-shaped groove 302, and the outer side of the T-shaped slider 14 is slidably connected to the inner side wall of the T-shaped groove 302, so as to increase the stability of the movement of the feeding frame 12 on the top of the support plate 3 by the sliding of the T-shaped slider 14 inside the T-shaped groove 302.

[0032] Furthermore, the outer ring surface of the rotating shaft 19 is rotatably connected to the inside of the limit block 18, and the bottom of the baffle 20 is in contact with the inclined plate 16 when the baffle 20 is in the vertical state, so as to ensure that the rotating shaft 19 rotates outside the limit block 18 by adjusting the angle of the baffle 20, which is convenient for feeding the materials on the weighing platform 17 through the second guide plate 15.

[0033] Further, a sliding connection is provided between the outer circumferential surface of the cylindrical block 21 and the inner side wall of the arc-shaped groove 1201, so as to ensure that when the electric telescopic rod 23 contracts to drive the two rotating shafts 19 on the baffle 20 to rotate inside the limiting block 18 for angle adjustment of the baffle 20, the cylindrical block 21 slides synchronously inside the arc-shaped groove 1201, thereby increasing the stability of the angle adjustment of the baffle 20.

[0034] Specifically, referring to Figure 7 , a rotating connection is provided between the top end of the electric telescopic rod 23 and the inner side wall of the U-shaped frame 22, and a rotating connection is provided between the end of the electric telescopic rod 23 away from the U-shaped frame 22 and the bottom end of the outer side surface of the baffle 20, so as to ensure that the baffle 20 is driven to perform angle adjustment by the contraction of the electric telescopic rod 23, facilitating the discharge of the weighed material on the weighing platform 17.

[0035] The working process of the present utility model: When using a feeding device for a wet screening device designed by this solution to feed the wet screening device, during the feeding process, first, the material is conveyed by the belt conveyor 1 through the first guide plate 2 to the weighing platform 17 of the feeding frame 12. The weighing platform 17 is electrically connected to the control panel 6 (the control panel is preferably a plc controller, with the model: CTSC-100 type, and the weighing platform model is XR-130). The weighing platform 17 can weigh the weight of the material conveyed by the belt conveyor 1. The weighing platform 17 weighs the material and the weight data is displayed through the control panel 6. When the weighing platform 17 weighs the weight of the material required as set by the control panel 6, the control panel 6 can control the belt conveyor 1 to pause the conveying, facilitating the weighing of the required material for conveying, realizing quantitative conveying into the wet screening device. The baffle 20 is driven to perform angle adjustment by the contraction of the electric telescopic rod 23, so that the baffle 20 no longer blocks the material. When the electric telescopic rod 23 contracts to drive the two rotating shafts 19 on the baffle 20 to rotate inside the limiting block 18 for angle adjustment of the baffle 20, the cylindrical block 21 slides synchronously inside the arc-shaped groove 1201, thereby increasing the stability of the angle adjustment of the baffle 20. Finally, the driving motor 8 drives the elliptical block 9 to rotate, and the elliptical block 9 rotates to squeeze the fixed block 13, causing the feeding frame 12 to move on the top of the support plate 3 and squeezing the two return springs 11. As the elliptical block 9 rotates in a cycle and continuously squeezes the fixed block 13, the feeding frame 12 reciprocates on the top of the support plate 3 to generate vibration, facilitating the feeding of the material on the weighing platform 17 without causing blockage. Since the inclined plate 16 and the weighing platform 17 are inclined, the vibration of the material facilitates feeding through the second guide plate 15.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
