Description

Technical Field

[0001] The present application belongs to the technical field of material powder screening, and specifically relates to a powder screening device. Background Art

[0002] Fly ash is the fine ash in the flue gas after coal combustion, and is also the main solid waste discharged by coal-fired power plants. Its main components are SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2, etc. Since fly ash contains aluminum, fly ash can be used to produce polyaluminium chloride.

[0003] Fly ash has a low bulk density and is prone to dust pollution. Therefore, in order to facilitate the transportation of fly ash from power plants to chemical plants as raw materials for the production of polyaluminium chloride, fly ash is pressed into easy-to-stack cubic blocks. After being transported to the chemical plant, the blocky fly ash is first crushed by a pulveriser, and then the crushed blocky fly ash is transported to a screening machine for screening. In this process, since the blocky fly ash needs to be transferred from the pulveriser to the screening machine after being crushed, it is easy to cause low production efficiency of fly ash. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a fly ash screening device that can solve the problem of low fly ash production efficiency.

[0024] The mounting bracket 100 can provide a mounting base for other mechanisms of the powder screening device, so as to facilitate the installation of other mechanisms.

[0025] The pulverizing device can be used to pulverize materials, such as fly ash. The pulverizing device may include a pulverizing container 210, a pulverizing cutter 220, and a driving mechanism 230. The pulverizing container 210 is disposed on the mounting bracket 100, and the pulverizing container 210 has a material outlet 211 and a material inlet 212. The pulverizing cutter 220 is at least partially disposed in the pulverizing container 210, and the driving mechanism 230 is connected to the pulverizing cutter 220. After the fly ash is placed into the pulverizing container 210 through the material inlet 212, the driving mechanism 230 drives the pulverizing cutter 220 to work, and the pulverizing cutter 220 pulverizes the fly ash, and the fly ash is discharged through the material outlet 211 after being pulverized. The pulverizing cutter 220 may include a connecting piece and a pulverizing blade.

[0026] The screening device 300 can be used to screen materials. The screening device 300 can include a screening mechanism 310 and a vibrating mechanism 320. The screening mechanism 310 is disposed on the mounting bracket 100 and faces the material outlet 211. The vibrating mechanism 320 is connected to the screening mechanism 310. After the fly ash is discharged from the material outlet 211, it enters the screening mechanism 310. The vibrating mechanism 320 drives the screening mechanism 310 to vibrate and screen the crushed fly ash.

[0027] The control device 400 can be used to control the driving mechanism 230 and the vibration mechanism 320, and the control device 400 is respectively connected to the driving mechanism 230 and the vibration mechanism 320. The control device 400 can include a controller and a display screen.

[0028] In an embodiment of the present application, after the fly ash is placed in the crushing container 210, the driving mechanism 230 drives the crushing tool 220 to work, and the crushing tool 220 crushes the fly ash. After the fly ash is crushed, it can directly enter the screening mechanism 310 through the material outlet 211. The vibration mechanism 320 drives the screening mechanism 310 to vibrate to screen the crushed fly ash, thereby improving the production efficiency of the fly ash.

[0029] In an optional embodiment, the pulverizing device may further include a hydraulic telescopic support 240, the hydraulic telescopic support 240 is disposed on the mounting bracket 100, the driving mechanism 230 and the control device 400 are both connected to the hydraulic telescopic support 240, and the control device 400 may control the pulverizing cutter 220 to move in the pulverizing container 210 through the hydraulic telescopic support 240. The control device 400 may control the hydraulic telescopic support 240 to extend and retract, thereby controlling the pulverizing cutter 220 to move in the pulverizing container 210 through the driving mechanism 230 to meet the requirements at different positions.

[0030] When the vibration mechanism 320 drives the screening mechanism 310 to vibrate, it is easy to transfer energy to the crushing device, thereby driving the crushing device to vibrate. In order to reduce this effect, the powder screening device can also include a soft connection structure 500, and the screening mechanism 310 is connected to the crushing device through the soft connection structure 500. The soft connection structure 500 can reduce the transmission of vibration. The soft connection structure 500 can be rubber.

[0031] When fly ash is screened, it is easy to diffuse in the air due to its small particle size, causing dust pollution. In order to solve this problem, the screening device 300 may further include a housing 330, which is connected to the soft connection structure 500, and the screening mechanism 310 is slidably arranged in the housing 330. The vibration mechanism 320 drives the screening mechanism 310 to vibrate in the housing 330, and the housing 330 can reduce the diffusion of fly ash into the air, which is conducive to reducing dust pollution.

[0032] In an optional embodiment, in order to facilitate taking out the screening mechanism 310 from the accommodating shell 330, one of the screening mechanism 310 and the accommodating shell 330 is provided with a slideway and the other is provided with a slide rail, and the slide rail and the slideway are slidably matched.

The driving source 321 can drive the cam 322 to rotate, and when the cam 322 rotates, the accommodating shell 330 is driven to move through the transmission rod 323, so that the accommodating shell 330 vibrates. This structural design is relatively simple.

[0034] In an optional embodiment, the screening mechanism 310 may include a primary screen 311 and a collecting container 312 , and the collecting container 312 is disposed on a side of the primary screen 311 away from the material outlet 211 , thereby facilitating the collection of fly ash.
