Abstract
The utility model discloses a pneumatic heating ore drawing hopper device and belongs to the technical field of mechanized equipment in mining industry. The pneumatic heating ore drawing hopper device consists of an air heater (1), an inlet pipe (2), an ore drawing hopper heating box (3), an ore drawing hopper (4), an air return pipe (5) and an insulating layer (6), and is characterized in that the air heater (1) is connected with the ore drawing hopper heating box (3) in a sealing way through the inlet pipe (2) and the air return pipe (5) to form a circulation path. The insulating layer (6) made of an iron plate is connected on the outside of the ore drawing hopper (4) in a welding way to form a sealed hopper heating box structure (3); the inlet pipe (2) is arranged on the bottom of the ore drawing hopper heating box (3); and the air return pipe (5) is arranged on the upper part of the ore drawing hopper heating box (3). As the insulating layer and the air heater are additionally arranged on the outside of the ore drawing hopper, the temperature of the ore drawing hopper can be kept, and therefore the icing phenomenon of wet ore in the ore drawing hopper can be prevented when the temperature is too low in winter. The device is convenient and practical, simple in structure, and easy to operate, the harm to manual operation caused by low temperature in winter can be reduced, and the lifting capability can be improved.
Description
Technical field:
The utility model relates to a kind of drawing chute device, and particularly a kind of pneumatic heated type drawing chute device that uses suitable cold winter belongs to mining industry mechanized equipment technical field.
Background technology:
At present, the drawing chute that mining is already used always, owing to cold in winter, the ore that temperature is low excessively, the down-hole promotes contains certain moisture, to cause funnel to stop up ore drawing smooth even can't ore drawing and often freeze, and often needs artificial mediation cleaning, influences hoisting capacity, strengthen personnel's labor content, reduced production efficiency.
Summary of the invention:
The purpose of this utility model is exactly will provide that a kind of convenience is suitable, simple in structure, easy operating, operate steadily, effectively improve the freeze device of phenomenon of wet ore deposit in winter in drawing chute.
The purpose of this utility model is achieved in that this pneumatic heated type drawing chute device is made up of the warm case 3 of hot air heating 1, air inlet pipe 2, drawing chute, drawing chute 4, backwind tube 5, heat-insulation layer 6.It is characterized in that the warm case 3 of hot air heating 1 and drawing chute links to each other and forms circulating path by air inlet pipe 2, backwind tube 5 sealings.
Outside the described drawing chute 4 iron plate heat-insulation layer 6 processed is arranged.
Described drawing chute 4 forms the warm box structure 3 of airtight funnel with heat-insulation layer 6.
Described air inlet pipe 2 is arranged on warm case 3 bottoms of drawing chute, and backwind tube 5 is arranged on warm case 3 tops of drawing chute.
The utility model compared with prior art has the following advantages:
Because the drawing chute outside added heat-insulation layer and the device of air that can heat, can make funnel continue insulation, thereby can prevent that winter temperature from crossing when low, the ore that contains moisture freezes at the funnel inwall and causes ore drawing smooth or can not the ore drawing phenomenon.Convenient suitable, simple in structure, the easy operating of this device is effectively avoided the outdoor low temp operation injury of workman, improves hoisting capacity, and very high using value is arranged under cryogenic conditions.Guarantee ordinary production, improved production efficiency.
Description of drawings:
Accompanying drawing is the utility model scheme drawing.
1, hot air heating; 2, air inlet pipe; 3, the warm case of drawing chute; 4, drawing chute; 5, backwind tube; 6, heat-insulation layer.
The specific embodiment:
Hot air heating 1 links to each other and forms circulating path by air inlet pipe 2, backwind tube 5 sealings with the warm case 3 of drawing chute.Iron plate heat-insulation layer 6 processed is arranged outside the drawing chute 4.Drawing chute 4 forms the warm box structure 3 of airtight funnel with heat-insulation layer 6.Air inlet pipe 2 is arranged on warm case 3 bottoms of drawing chute, and backwind tube 5 is arranged on warm case 3 tops of drawing chute.
During use, the hot gas that hot air heating provides enters the warm box structure of funnel by warm case bottom inflow pipe, forms the cycling hot air-flow in airtight warm case, makes funnel continue insulation, returns through backwind tube again.Can use.
