Aiming at the deficiencies of the prior art, the purpose of this utility model is to provide a screening device for cement mill steel ball steel forging, which can avoid equipment damage and production accidents, can not only reduce the labor load of workers, but also shorten the sorting time, greatly improving work efficiency.

In order to achieve the above object, the utility model is achieved through the following technical solutions: a screening device for cement mill steel ball steel forging, including a vibrating screen, a vibrating motor and a first support, the vibrating screen includes a screen, fixedly connected to the The two side baffles on the long side of the screen and the back baffle fixedly connected to the short side of the screen, the side baffles are connected to the adjacent end of the back baffle, and the screen is opposite to the back baffle One end is provided with a finished product outlet, and a guide trough with an upper opening larger than a lower opening is provided under the screen, and a waste ball forging outlet is provided under the guide trough, and the vibration motor is fixedly installed on the outer side of the rear baffle and connected to the The screen is connected, the vibrating screen is suspended on the first bracket by more than 4 springs, the spring near the rear baffle is shorter than the length of the spring near the finished product outlet, and a ring-shaped supporting vibrating screen is arranged below the screen and A second bracket inclined downward along the length of the screen, the end of the second bracket near the screen rear baffle is higher than the end near the outlet of the screen finished product, and the second bracket is fixed on the first bracket by a support rod , the vibrating screen is in contact with the second support before vibrating.

To further illustrate, the acute angle between the second bracket and the horizontal plane is 5°-10°.

To further illustrate, it also includes eccentric blocks, which are installed on both sides of the vibrating screen.

To further illustrate, universal wheels are provided at the bottom end of the first support frame.

Compared with the prior art, the utility model has the following beneficial effects: the vibrating screen is placed at the exit of the cement mill to ensure that the steel balls that need to be screened flow to the vibrating screen, driven by the vibrating motor, so that the entire vibration The sieve swings, the steel balls and steel forgings can move freely, and the steel balls and steel forgings that do not meet the requirements will fall from the screen grid and enter the guide groove, and then lead out from the waste ball forging outlet. Rolls on the net and flows out of the finished product outlet. Due to the inclined setting of the second bracket and the screen, the qualified steel balls and steel forgings can flow out quickly during the vibration process, and it can also prevent the end of the screen near the rear baffle from being lower than the end of the finished product outlet when there are overweight materials. As a result, qualified materials cannot flow out of the finished product outlet, avoiding equipment damage and production accidents, which can not only reduce the labor load of workers, but also shorten the sorting time and greatly improve work efficiency.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail, but does not limit protection scope and application scope of the utility model:

As shown in Figure 1, a screening device for cement mill steel ball steel forging includes a vibrating screen 1, a vibrating motor 2 and a first bracket 3, the vibrating screen 1 includes a screen 11 fixedly connected to the long side of the screen 11 The two side baffles 14 on the top and the back baffle 15 fixedly connected on the short side of the screen 11, the side baffles 14 are connected to the adjacent ends of the back baffle 15, so as to prevent the screening from passing through the side baffles 14 or the rear baffles. The baffle plate 15 falls, and a finished product outlet 12 is provided at the opposite end of the screen 11 to the rear baffle 15, and a material guide 16 with an upper opening larger than a lower opening is arranged below the screen 11, and the material guide 16 The bottom is provided with a waste ball forging outlet 13, and the vibrating motor 2 is fixedly mounted on the outer side of the tailgate 15 and connected with the screen 11. The vibrating screen 1 is suspended on the first support 3 by more than 4 springs 5, close to the The spring 5 of the tailgate 15 is shorter than the length of the spring 5 close to the finished product outlet 12, so that the screen 11 has an acute angle with the horizontal plane of 5 degrees, 8 degrees or 10 degrees, and the preferred screen 11 has an acute angle with the horizontal plane. When the temperature is 5 degrees, the screening efficiency is the best. The bottom of the screen 11 is provided with a circular support vibrating screen 1 and a rectangular second bracket 17 inclined downward along the length direction of the screen 11. The end of the second bracket 17 near the screen 11 rear baffle 15 is higher than One end of the finished product outlet 12 of the screen cloth 11, the acute angle included angle between the second support 17 and the horizontal plane is 5 degrees, 8 degrees or 10 degrees, and when the preferred second support 17 and the acute angle included angle of the horizontal plane are 5 degrees, the screening efficiency is the best. good. Adopting the second support 17 can also avoid that the qualified material cannot flow out of the finished product outlet 12 when there is material at one end of the screen cloth 11 near the tailgate 15 when there is material lower than the finished product outlet 12. The second support 17 is fixed on the On the first support 3, the vibrating screen 1 is in contact with the second support 17 before vibrating.

When using this device, the vibrating screen 1 is placed at the exit of the cement mill to ensure that the steel balls to be screened flow to the vibrating screen 1, driven by the vibrating motor 2, so that the entire vibrating screen 1 swings, and the steel balls and steel The forging can move freely, and the steel balls that do not meet the requirements will fall into the grid of the screen 11, enter the guide groove 16, and then be exported from the waste ball forging outlet 13, and the steel balls that meet the standards are placed on the inclined screen 11 Roll and flow out from finished product outlet 12. Due to the inclined setting of the second bracket 17 and the screen 11, the qualified steel balls and steel forgings can flow out quickly during the vibration process, and at the same time, it can also prevent the end of the screen 11 close to the rear baffle 15 from being lower than the finished product outlet when there are overweight materials. One end of 12 causes qualified materials to not flow out of the finished product outlet 12, avoiding equipment damage and production accidents, which can not only reduce the labor load of workers, but also shorten the sorting time, greatly improving work efficiency.
