Device for collecting material at bottom of prilling tower

Abstract

The invention discloses a device for collecting a material at the bottom of a prilling tower, and relates to a raw material prilling device. The device comprises a material collecting disc, a discharge tube, a drive motor and a fixing base installed at the bottom of the prilling tower; the discharge tube is arranged in the fixing base, the material collecting disc is arranged on the fixing base and is rotationally connected with the fixing base, the drive motor is installed on the fixing base, the drive motor drives the material collecting disc to rotate, the material collecting disc is provided with a material leakage hole formed radially along the material collecting disc, a C-shaped material conveying groove fixed with the material collecting disc is formed below the material leakage hole, one end of the C-shaped material conveying groove extends into the discharge tube, the C-shaped material conveying groove is internally provided with a spiral material conveying shaft driven by the drive motor and rotationally connected with the material collecting disc, a material scraping plate connected onto the side wall of the prilling tower is arranged above the material collecting disc, a water circulation channel is arranged in the material scraping plate, and the lower end of the material scraping plate is in contact with the material collecting disc. Due to the device, the material is gathered around the spiral material conveying shaft, the material conveying efficiency is improved, and moreover, the material scraping efficiency is also improved, and the material is cooled.

Description

technical field [0001] The invention relates to a device for granulating raw materials, in particular to a material collecting device at the bottom of a granulation tower. Background technique [0002] In the prior art, the discharge equipment at the bottom of the compound fertilizer granulation tower is often transported by a belt conveyor. Due to the large diameter of the tower, in order to output all the falling materials, multiple belt conveyors are required for conveying. Although this conveying method can transport materials out, there are many disadvantages; the high cost of the belt conveyor increases the production cost, and the parts need to be replaced frequently, the service life is short, and the maintenance process is extremely cumbersome; moreover, the material is falling The dust generated in the process will fly out through the gap of the belt conveyor at the bottom of the tower, and the sealing effect is poor, making the production environment of the worksh...

Problems solved by technology

[0004] Because the screw feeder in this device cannot be in contact with the surface of the receiving disc, the scraping effect is not good; and because the screw feeder is in an open space, the materials cannot be gathered around the screw feeder, so the screw feeder's The delivery effect is not good

In addition, because the temperature of the material is still high when it falls on the receiving disc, the conveyor belt is easy to age quickly after the material is put into the conveyor belt without cooling down.
