Description

TECHNICAL FIELD

[0002] The vibrating screen is a kind of mechanical equipment for screening and grading granular and powdery materials, which plays a key role in many industries.

[0003] The traditional material processing process often operates screening and crushing as two independent processes. First, the original material is preliminarily screened by using the vibrating screen to screen out the material meeting the specific particle size requirement, and the larger particle material not meeting the screen mesh aperture is separated out and waits for subsequent crushing processing. Then, the larger particle material is conveyed to a dedicated crusher for crushing operation, and the crushed material is returned to the vibrating screen for secondary screening to ensure that the particle size meets the production requirement. This separation type processing method can meet the basic production requirement to some extent, but has the following disadvantages:

[0004] On the one hand, the two independent operation processes not only increase the equipment investment cost and floor area, but also make the whole production process long and complex, and the material transfer process between different equipment consumes a large amount of time and energy, seriously affecting the improvement of production efficiency. On the other hand, due to the lack of effective cooperation between the screening and crushing processes, it is often found that the crushed material still has some particles not meeting the requirement in the secondary screening process, which needs to be crushed and screened again, which undoubtedly further aggravates the waste of energy and the increase of production cost, and also makes it difficult to ensure the uniformity and stability of the product particle size.

[0030] Please refer to Figures 1-7The utility model embodiment provides a kind of auxiliary broken material function's vibrating screen, including mounting frame 1, mounting frame 1 upper end one side is fixedly installed with feeder 7, the both sides of mounting frame 1 are provided with connecting mechanism 3, connecting mechanism 3 bottom is connected with vibration box 4, vibration box 4 bottom is installed with vibration motor 5, vibration box 4 is installed with screen 8, mounting frame 1 upper end other side is installed with adjusting mechanism 2, adjusting mechanism 2 bottom is installed with broken material plate 6.

[0031] In the application, material falls into screen 8 from feeder 7, is driven vibration box 4 and screen 8 vibration by vibration motor 5, so that the material meeting the aperture of screen 8 falls into the discharge channel formed between vibration box 4 and screen 8, slides out along the inclined inner wall of the bottom of vibration box 4, and realizes the screening of the material.

[0032] Broken material plate 6 is fixedly installed on adjusting mechanism 2, and adjusting mechanism 2 is fixedly installed on mounting frame 1. During the vibrating screening process, the position of broken material plate 6 is fixed. The vibration of screen 8 makes the material meeting the aperture of screen 8 pass through screen 8 and fall down. The material larger than the aperture of screen 8 remains on screen 8. With the vibration of screen 8, the material is broken into smaller particles due to the extrusion of screen 8 and broken material plate 6 until it meets the aperture of screen 8.

[0033] Through the above arrangement, the screening efficiency of the material and the uniformity of the finished product can be improved, and the secondary crushing and screening of the material can be avoided, thereby improving the production efficiency.

[0034] One end of vibration box 4 close to feeder 7 is provided with a material guide part 41, and the material guide part 41 is inclinedly arranged below feeder 7.

[0035] In the application, the inclined material guide part 41 is beneficial to preliminarily forming a certain layer distribution of the material before entering screen 8, so that the initial state of the material on screen 8 is more regular. In this way, after the vibrating screen starts to work, the material can more efficiently spread and screen on screen 8, and a large amount of material can be prevented from accumulating on screen 8.

[0036] Connecting mechanism 3 includes a fixed frame 31 and a hook 32, and the fixed frame 31 and the hook 32 are fixedly installed on one side of mounting frame 1 and vibration box 4 respectively.
