Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] refer to figure 1 and figure 2 , is a lime production system disclosed in the present invention, which includes a kiln body 1 and an ash unloading device 2 installed on the lower end of the kiln body 1 . The ash unloading device 2 consists of a receiving hopper 3 , an ash discharger 4 , a first ash unloading hopper 5 and a second ash unloading hopper 6 connected in sequence from top to bottom.

[0033] refer to figure 2 and image 3, the upper end of the receiving bucket 3 is fixedly connected with the bottom end of the kiln body 1, and four lower feeding cylinders 31 are welded on the bottom surface of the receiving bucket 3. The cross-section of one end connected is larger than the end away from the bottom surface of the receiving bucket 3 . In the projection of each lower barrel 31 on the horizontal plane, the centers of each projection are l...

Abstract

The invention relates to a lime production system. The lime production system comprises a kiln body and an ash discharging device, wherein the ash discharging device comprises a receiving hopper, a ash discharging machine, a first ash discharging hopper and a second ash discharging hopper which are sequentially connected to one another from top to bottom; the ash discharging device is connected with a blower; the blower is connected with a blower pipe; the first ash discharging hopper is conical, and the axis of the cone is parallel to the horizontal plane; the lower end of the first ash discharging hopper is a conical sharp end, and the upper end of the second ash discharging hopper is connected with a feeding valve; the lower end of the first ash discharging hopper is connected with a feeding valve on the second ash discharging hopper; the end, which is away from the blower, of the blower pipe is connected with a side surface of the first ash discharging hopper; the axis of the end,which is away from the blower, of the blower pipe is tangent to the outer side surface of the first ash discharging hopper; a coal ash discharging box is arranged on one side of the first ash discharging hopper; and the upper end of the coal ash discharging box is connected with a first coal ash discharging pipe and a second coal ash discharging pipe. By the lime production system, the amount of pulverized coal in produced lime can be reduced, and the quality of the lime is improved.

Description

technical field [0001] The invention relates to the technical field of equipment for generating quicklime from limestone, in particular to a lime production system. Background technique [0002] The current quicklime is usually produced by calcination of limestone. The traditional production process is to put limestone and fuel into the lime kiln, decompose after preheating to 850°C, complete the calcination when it reaches 1200°C, and finally cool it, and then discharge it out of the kiln. outside. Lime kiln is mainly composed of kiln body, feeding device, material distributing device, combustion device, ash unloading device, dust removal device and electric control device. Lime shaft kilns are widely used at present. Lime shaft kilns adopt the principle of countercurrent preheating and calcination. Bottom-up and reverse movement of materials, different thermal processes are performed in the above-mentioned areas. Combustion-supporting air enters at the bottom of the kil...
