Throwing machine
●Throwing machine
Throwing machine is a commonly used equipment in the field of non-ferrous metal pyrometallurgy. The throwing machine is installed next to the feeding port of the roasting furnace, so that the materials discharged from the material distributor, such as concentrate powder and other similar fine powder and small granular materials, are thrown into the roasting furnace or other equipment at a high speed, so that the roasting furnace or the Other equipment can roast the material better.
●Working process and working principle:
When the material needs to be transported to the designated position, push the ejector to the corresponding position, and then load the material into the ejector through the feeding port, and the material falls to the driving pinch pulley, which drives the drive under the action of the driving device. The pinch roller rotates, which in turn drives the throwing belt to rotate. The material falls on the throwing belt running at high speed, and the material is transported forward through the throwing belt. When it reaches the end of the conveyor belt, the material will be thrown out of the host under the action of inertia. The shell 3 is finally shot to the position where feeding is required.
By adjusting the tension of the No. 1 tensioning drum, the No. 2 tensioning drum and the driving pinch roller, the tension of the throwing belt and the throwing direction can be adjusted, and the throwing distance can be adjusted at the same time.
●The main structure of the throwing machine:
Including host shell, pallet, steering wheel, collecting hopper, manhole door, pulling arm, throwing device, driving device, tensioning device, walking mechanism, safety cover, switch device, electric control device, etc.
The throwing device includes the No. 1 tensioning drum, the No. 2 tensioning drum and the driving pinch roller. The No. 1 tensioning drum, the No. 2 tensioning drum and the driving pinch wheel are wound with a throwing belt. device is connected.
The main shaft of the No. 1 tensioning roller is installed on the horizontal chute of the main frame to form a sliding fit, and the tensioning degree is adjusted by the screw tensioning device.
The main shaft that drives the pinch pulley is installed on the No. 1 vertical chute of the main frame to form a sliding fit, and the tensioning degree is adjusted by the screw tensioning device.
The main shaft of the No. 2 tensioning drum is installed on the No. 2 vertical chute of the main frame to form a sliding fit, and the tensioning degree is adjusted by the screw tensioning device.
The top of the mainframe casing is provided with a top observation door, and the rear side is provided with a rear observation door.
This machine is provided with a movable steering running mechanism, which requires a light and compact structure to reduce power consumption and be flexible in use. In order to reduce the labor intensity of workers when moving the throwing machine, the machine is equipped with an automatic traveling mechanism and is equipped with a brake.
The annular tape used in this machine is a wear-resistant and strong throwing belt. The material is added from the middle of the driving pinch roller. The annular belt moves at a high speed through the tension roller and the driving pinch wheel. Due to inertia, the material is thrown into the container, such as a container. , incinerators, etc.
In order to achieve the purpose of adjusting the throwing distance and angle, two tensioning rollers and one driving pinch roller on the annular tape can realize the adjustment function.
In order to prevent the material from spilling during the conveying process, a collecting hopper is set under the conveying belt, and a clearing door is set; the collecting hopper can also be connected with the storage conveyor to recover the scattered materials.
