Abstract

The utility model discloses a vertical type drying kiln with high efficiency. The main body of the utility model adopt a vertical type device; the vertical type drying kiln with high efficiency is mainly composed of a chassis, a barrel body, a combustion chamber, a material storage, a chimney, a discharge hopper, an exhaust fan of an auxiliary device, an electromagnetic vibration feeder, an elevator, a belt conveyer, etc.; material is elevated to the material storage on the top of the drying kiln by the elevator; the material can be guided by a furnace core conical hopper of a cutoff device and an exhaust conical hopper for blocking the material to fall uniformly and be dried; the material can settle naturally depending on gravity; the dried material can be centralized to the bottom of a furnace chamber; the material can be discharged from the discharge hopper through electric vibration of the electromagnetic vibration feeder and carried away by the belt conveyer. The utility model has the advantages of simple and reasonable structure, low energy consumption, high thermal efficiency, and little pollution, and the utility model is suitable for drying slag, clay, and other agglomerate, granular, and powdery material of a cement plant.

Description

The highly effective energy-conserving vertical drying kiln

The utility model discloses a kind of drying plant, particularly a kind of highly effective energy-conserving vertical drying kiln.

Drying materials is one of important step of cement production process, the legacy equipment that is used for drying materials is a rotary drum drying machine, but this dryer floor space is big, the cost height, to material and water content bad adaptability, and heat loss is big, the thermal efficiency is low, hear rate is high, kiln discharge moisture content is difficult to control, seriously polluted.

The purpose of this utility model is exactly that a kind of simple and reasonable, simple to operate, easy to maintenance, less energy consumption, pollution is little, economic benefit is high highly effective energy-conserving vertical drying kiln will be provided.

For achieving the above object, the utility model adopts technical scheme as described below: the highly effective energy-conserving vertical drying kiln is made up of chassis, cylindrical shell, combustion chamber, feed bin, chimney, dump skip and auxiliary equipment air exhauster, electro-vibrating feeder, elevator and belt conveyor etc.Have some blast pipes from the bottom to top to come together in the house steward of cylindrical shell top around the cylindrical shell, the house steward exit is equipped with an air exhauster.Cylindrical shell and dump skip respectively with some uniform bolts be installed on the top of chassis and below.One core stove is arranged on the chassis, and fire door and shutter are arranged at core stove bottom, and the installation direction of fire door can be selected arbitrarily except that the elevator position; Refractory brick, bell become the combustion chamber with the combustion chamber awl bucket that array is superimposed with each other with backgauge exhaust cone bucket shape, and top, combustion chamber is provided with backgauge hood and chimney; The fire bars of furnace bottom adopts ZG45# or heat-resisting cast iron; Inner barrel is welded with reinforcement and the uniform lightweight I-beam of array supports.There is a feed bin cylindrical shell top; Drying kiln one side is equipped with elevator, and electro-vibrating feeder is installed in the lower end of dump skip, and there is a belt conveyor its below.

Adopt the utility model floor space of this structure little, simple in structure, less energy consumption, pollution is little, economic benefit is high, the life-span is long.The utility model is applicable to the oven dry of block, sticking shape such as cement plant slag, clay and granular material.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the structural representation of facing of the present utility model.

Fig. 2 is the A-A schematic diagram of Fig. 1.

With reference to Fig. 1, Fig. 2.The highly effective energy-conserving vertical drying kiln is made up of chassis 5, cylindrical shell 21, combustion chamber 22, feed bin 15, chimney 18, dump skip 4 and auxiliary equipment air exhauster 16, electro-vibrating feeder 3, elevator 17 and belt conveyor 2 etc.Have some blast pipes 6 from the bottom to top to come together in the house steward of cylindrical shell top around the cylindrical shell 21, the house steward exit is equipped with an air exhauster 16, and the steam that produces in the kiln is expelled from kiln.Cylindrical shell and dump skip 4 respectively with some uniform bolts be installed on the top of chassis 5 and below so that the assembling and the maintenance.One core stove is arranged, the coal-fired heat of the big limit land productivity of energy on the chassis.Fire door 8 and shutter 20 are arranged at core stove bottom, and the installation direction of fire door can be selected arbitrarily except that the elevator position; Refractory brick 9, bell 13 form combustion chamber 22 with combustion chamber awl bucket 12 and the backgauge exhaust cone bucket 11 that array is superimposed with each other, and top, combustion chamber is provided with backgauge hood 14 and chimney 18 discharges out of the furnace the flue gas of generation; The fire bars of furnace bottom adopts ZG45# or heat-resisting cast iron; In order to strengthen the intensity of cylindrical shell, inner barrel is welded with reinforcement 19 and the uniform lightweight I-beam of array supports 10.There is a feed bin 15 the cylindrical shell top; Drying kiln one side is equipped with elevator 17, and electro-vibrating feeder 3 is installed in the lower end of dump skip 4, and there is a belt conveyor 2 its below.Material is promoted to drying kiln top feed bin 15 by elevator, evenly fall and oven dry by cut-off equipment backgauge exhaust cone bucket 11 directing materials in the kiln, rely on the gravity natural subsidence, the material after the oven dry is concentrated to burner hearth bottom dump skip 4, by the discharging of shaking of electro-vibrating feeder 3 electricity.
