Problems solved by technology

[0002] At present, for the drying of mineral materials, especially for the titanium concentrate selected from the tailings of vanadium-titanium magnetite after iron selection, the drum type is generally used. The main principle is to pass the high-temperature gas formed by combustion in the furnace into the rotary dryer, and at the same time transport the titanium concentrate to the rotary dryer, and the rotation of the rotary dryer drives the titanium The concentrate rotates so that the titanium concentrate is turned over in the dryer, and the titanium concentrate is dried under the action of high-temperature gas. Generally, the titanium concentrate can reach up to 70 degrees after drying. If it is necessary to dry the titanium concentrate If the temperature reaches above 200 degrees, the existing equipment can not meet the requirements, and some high-temperature methods such as converters can be used to roast titanium concentrates at a temperature above 1000 degrees, but due to the complexity of the equipment, the cost is quite high. The roasting method cannot meet its requirements

Embodiment 1

[0021] Such as figure 1 , figure 2 As shown, a high-temperature dryer for mineral materials includes a material bin 1, a support column 2, and a heating chamber 3. The material bin 1 is a box structure with an inlet 4 on the top and an outlet 6 on the bottom. .

[0022] The material bin 1 is provided with 4 sloping plates 5, which are set opposite to each other. The angle between each sloping plate and the horizontal is 15 degrees. The wall 7 is formed with a leak 9, and the bottom of the material bin 1 is provided with a heating plate 10. The heating plate 10 is inclined, and the angle between the heating plate 10 and the horizontal is 15 degrees. The lower end of the heating plate 10 is connected to the discharge port 6.

[0023] A smoke guide plate 8 is arranged in the leak 9 formed by the inclined plate 5 adjacent to the heating plate 10 and the material bin wall 7, the low end of the smoke guide plate 8 is connected with the high end of the heating plate 10, and the hi...

Embodiment 2

[0030] In the case that the high-temperature dryer is different except for the heating chamber and other settings are the same, it is mainly realized by burning natural gas or coal gas in the heating chamber. In this case, the furnace wall of the heating chamber can also use the same Structure, refractory bricks and insulation layer structure can be used as the furnace wall, only nozzles and ignition devices for burning natural gas or gas are installed in the furnace, and the drying temperature is controlled by controlling the size of the natural gas. When this method is adopted, the impact on the environment is small, especially the natural gas basically has no environmental pollution.

Embodiment 3

[0032] Electric heating equipment can also be set in the heating chamber of the high-temperature dryer for heating the heating plate. By arranging resistance wires in the heating chamber, generally several groups of resistance wires are arranged along the bottom of the heating plate, and the size of the load can be controlled by controlling different groups of resistance wires, and the drying temperature can be precisely controlled. When this method is used, there is no impact on the environment, but the electricity cost is relatively high.

Abstract

The invention relates to a high-temperature dryer for mineral material. The high-temperature dryer comprises a material storage bin, a support pillar and a heating cavity, wherein a feeding hole is formed in the top of the material storage bin; an inclined plate is arranged in the material storage bin; a leakage hole is formed by the lower end of the inclined plate and the wall of the material storage bin; the bottom of the material storage bin is provided with a heating plate; the heating plate is arranged in an inclined way; the lower end of the heating plate is connected with a discharge hole; a smoke guide plate is arranged in a leakage hole formed by the inclined plate close to the heating plate and the wall of the material storage bin; a smoke guide hole is formed by the smoke guide plate and the wall of the material storage bin; a material leaking hole is formed by the smoke guide plate and the lower end of the inclined plate close to the heating plate; the material storage bin is supported by the support pillar through a spring; the heating cavity is arranged under the material storage bin; a vibrator is also arranged on the top of the material storage bin. The high-temperature dryer is simple in structure and easy to distinguish, fully utilizes a heat source and hot air, and enables the mineral material to obtain higher temperature.

Description

technical field [0001] The invention relates to a high-temperature dryer for mineral materials, which is particularly suitable for high-temperature drying of titanium concentrate powder or pellets selected from vanadium-titanium magnetite, and can realize roasting of titanium concentrate. Background technique [0002] At present, for the drying of mineral materials, especially for the titanium concentrate selected from the tailings of vanadium-titanium magnetite after iron selection, it is generally completed by drum dryer or rotary dryer. The high-temperature gas formed by burning inside is passed into the rotary dryer, and at the same time, the titanium concentrate is also transported into the rotary dryer. The rotation of the rotary dryer drives the rotation of the titanium concentrate, so that the titanium concentrate turns over in the dryer. Under the action of high-temperature gas, the titanium concentrate is dried. Generally, the titanium concentrate can reach about 7...
