Abstract
The utility model relates to a water cooling nitrogen sealing single-cylinder cooling machine, comprising a cooling machine body, wherein the upper surface and the lower surface of the outer side of the cooling machine body are provided with a cooling water sprinkling device and a cooling water recovery device respectively; an inlet and an outlet of the cooling machine body are connected with a nitrogen sealing device respectively. When the utility model works, materials enter the cooling machine body and are driven to ceaselessly roll by a rotary cylinder body, which dissipates the heat to the cylinder wall; the cooling water sprinkling device cools the cylinder wall, and the cooling water flowing down from the cylinder body is recovered in the cooling water sprinkling device by the cooling water recovery device. The advantages of the water cooling nitrogen sealing single-cylinder cooling machine are as follows: (1) the cooling effect is good, and the equipment is short in length, small in size, light in weight and low in cost; (2) the inert gas 'nitrogen' with a certain pressure forms 'gas curtains' on the inlet and the outlet, which makes the inner side of the rotary cylinder body separate from the outside and further prevents the appearance of the oxidation; (3) dusts in materials are not discarded, and the manufacturing cost and the using cost of the equipment are lower than those of an air cooling type equipment.
Description
Technical field
The utility model relates to a kind of single cylinder cooling machine, particularly a kind of single cylinder cooling machine of water cool nitrogen sealing.
Background technology
We know, in the pellet sintering process, need the pelletizing that sintering comes out be cooled off, and the widespread usage cooler cools off it at present.Traditional cooler is the mode that adopts the cooling of ventilating, and there are many shortcomings in this cold-zone mode; At first, when the pelletizing iron-holder surpasses 80%, airborne oxygen very easily with agglomerates of sintered pellets generation oxidation, cause material loss serious, formed huge waste.The second, because the specific heat capacity of wind is little, thus need the air quantity of cooling air very big, so the power height of blower fan, energy consumption is very big; The 3rd, in order to reach cooling effect, the length of equipment is generally all very long, causes overall dimension, tonnage, the cost of equipment all very high.The 4th, the dust in the material is kicked up, and also needs a cover dust collection system.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of efficient, low consumption, good cooling results, water cooling nitrogen-sealed single cylinder cooling machine that automaticity is high are provided.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of water cooling nitrogen-sealed single cylinder cooling machine, comprise the cooler body, cooler body exterior top and below be respectively equipped with cooling water flusher and cooling water retracting device, the entrance and exit of cooler body connects nitrogen gas seal equipment respectively.
Described cooling water flusher comprises cold water pipe and connected shower nozzle.
Described cooling water retracting device comprises cistern, is provided with in the cistern to add new water device and screen pack, and screen pack has water-delivery pump, and water-delivery pump is connected by the cold water pipe of pipeline with the cooling water flusher.
Described nitrogen gas seal equipment comprises gas pipeline and control valve, and control valve is located on the gas pipeline, and the appendix road junction is located at respectively in the entrance and exit of cooler body.
Described cooler body is installed on the ground, and cooler body left end inserts materials device, and right-hand member picks out materials device, and the cooler body comprises rotating cylinder and power set, and power set are connected with rotating cylinder.
During work, after material entered the cooler body, that does not stop under the drive of rotary barrel rolled, and heat is dispersed on the barrel, the cooling water flusher is implemented cooling to barrel, flows down cooling water from cylindrical shell and is recovered to the cooling water flusher again through the cooling water retracting device.
The beneficial effects of the utility model are:
(1) it is air-cooled to adopt the mode of water spray cooling to replace, big because specific heat of water holds, and good cooling results is so weak point, size, tonnage, cost are little for the length of equipment.
(2) form " gas curtain " with inert gas " nitrogen " at the place, gateway, rotating cylinder inside is isolated from the outside, stop oxygen to enter, the generation of anti-oxidation with certain pressure.
(3) dust in the material is not sublated, and gathering system can be done very for a short time, and the manufacturing of equipment, use cost " air-cooled " are low.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, feeding device, 2, the cooler body, 3, the cooling water flusher, 4, nitrogen gas seal equipment, 5, drawing mechanism, 6, cistern, 7, add new water device, 8, the cooling water retracting device, 9, cold water pipe, 10, shower nozzle, 11, gas pipeline, 12, control valve, 13, cylindrical shell.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, cooler body 2 comprises rotating cylinder 13 and power set, and power set are connected with rotating cylinder 13.Cooler body 2 links to each other with the basis, and its cylindrical shell 13 can be around self axis revolution, so that the heat of inner steel ball quickens to be distributed on the barrel.The cooler left end inserts materials device 1, and right-hand member picks out materials device 5.
Nitrogen gas seal equipment 4 comprises gas pipeline 11 and control valve 12, and control valve 12 is located on the gas pipeline 11, and the appendix road junction is located at respectively in the entrance and exit of cooler body 2.The inlet and the outlet of 4 pairs of cooler bodies 2 of nitrogen gas seal equipment seal; nitrogen with certain pressure; be transported to the sealing precalculated position through gas pipeline 11 and form gas curtain; material is not subjected to gas curtain to influence normal conveying; and air is isolated in the cylindrical shell outside by gas curtain, and then the protection material is not oxidated.
Cistern 6 is used to store the cooling water that is not evaporated that flows down from cylindrical shell 13, holds the cooling water that certain water level is arranged in the cistern, to guarantee the periodic duty of cooling water system 3.
After material enters cooler body 2 through feeding device 1, that does not stop under the drive of rotary barrel rolls, be dispersed into heat on the barrel rapidly, 3 pairs of barrels of cooling water flusher are implemented cooling, guarantee that the barrel temperature constant is in allowed band, the length of cylindrical shell is calculated through strict, when material when left end enters the right-hand member discharging, temperature drops to 300 ℃ from 1100 ℃.
