Abstract

The utility model discloses a fixed boiling cooling bed, which comprises an air bellow and a blast system connected at back of the air bellow, wherein the air bellow is connected with a boiling chamber; the boiling chamber and the air bellow are spaced via a boiling plate; air blowing holes are formed in the boiling plate; air caps are weld on the air blowing holes; a diffusion chamber is connected and communicated with the boiling chamber, and the diffusion chamber is provided with a dedusting outlet; a sand feeding port is arranged on one side of the boiling chamber, and a sand discharging port is arranged on the other side of the boiling chamber; a cooling water pipeline is further mounted in the boiling chamber, and the water inlet of the cooling water pipeline is formed at the rear position of the boiling chamber on the same side with the sand charging port; and the water outlet is arranged at the front position of the boiling chamber on the same side with the sand feeding port. The fixed boiling cooling bed integrates air cooling and water cooling, utilizes the cold air blasted by the blast system to enable hot sand to be in a boiling state, then utilizes converse water flow to exchange heat with the hot sand and cool the hot sand, the cooling effect is very ideal, and foundry sand temperature demand can be satisfied.

Description

A kind of fixed boiling is cooling bed

Technical field

The utility model relates to a kind of cooling device, and more particularly, it is cooling bed to relate in particular to a kind of fixed boiling.

Background technology

At casting industry, many Foundry Works are that mo(u)lding line does not arrange but equipment of reliable sand cooling in the sand preparing system of sand, perhaps be provided with but equipment of simple sand cooling, but cooling effect is undesirable, causes reaching during the broiling summer too high " hot sand " problem of old sand temperature that has occurred reuse in oepration at full load.The too high meeting of molding sand temperature causes a series of difficulty to moulding production, as the moulding-sand property instability, adheres to template easily, causes casting mold to damage; The adhesion sand hopper makes molding sand add sand and is obstructed; Mo(U)ld face dewaters easily and then causes the rising of casting wasted product rate and working condition deterioration etc.

The utility model content

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of fixed boiling cooling bed, the hot sand after the regeneration is cooled off, to satisfy the requirement of molding sand temperature.

For achieving the above object, fixed boiling provided by the utility model is cooling bed, comprises bellows and the blower system that is connected the bellows rear, be connected with boiling-house on the described bellows, separate by boiling plate between boiling-house and the bellows, be provided with gas hole at boiling plate, be welded with blast cap on the gas hole; Be connected with diffuser casing on the boiling-house, diffuser casing communicates with boiling-house, and diffuser casing is provided with the dedusting outlet; One side of boiling-house is provided with sand inlet, and opposite side is provided with sand export; Cooling water pipeline also is installed in the boiling-house, and the water inlet of this cooling water pipeline is located at the rear position with the boiling-house of sand export homonymy, and delivery port is located at the anterior position with the boiling-house of sand inlet homonymy.

The utility model integrates air-cooled and water-cooled, and the cold wind that utilizes blower system to blast makes hot sand be in fluidized state, and the current that recycling is reverse and hot sand carry out heat exchange, and hot sand is cooled off, and cooling effect is rather desirable, can satisfy the requirement of molding sand temperature.

Description of drawings

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

Fig. 2 is plan structure schematic diagram of the present utility model.

Among the figure: the 1-bellows; The 2-blower system; The 3-boiling-house; The 31-boiling plate; The 32-gas hole; The 33-blast cap; The 4-diffuser casing; 5-dedusting outlet; The 6-sand inlet; The 7-sand export; The 8-water inlet; The 9-delivery port.

The specific embodiment

The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.

Consult illustrated in figures 1 and 2, a kind of fixed boiling provided by the utility model is cooling bed, comprise bellows 1 and the blower system 2 that is connected bellows 1 rear, be connected with boiling-house 3 on the bellows 1, separate by boiling plate 31 between boiling-house 3 and the bellows 1, be provided with gas hole 32 at boiling plate 31, be welded with blast cap 33 on the gas hole 32.Be connected with diffuser casing 4 on the boiling-house 3, diffuser casing 4 communicates with boiling-house 3, and diffuser casing 4 is provided with dedusting outlet 5.One side of boiling-house 3 is provided with sand inlet 6, opposite side is provided with sand export 7, cooling water pipeline also is installed in the boiling-house 3, and the water inlet 8 of this cooling water pipeline is located at the rear position with the boiling-house 3 of sand export 7 homonymies, and delivery port 9 is located at the anterior position with the boiling-house 3 of sand inlet 6 homonymies.

The course of work of the present utility model is: the hot sand after the regeneration enters boiling-house 3 from sand inlet 6, utilize blower system 2 to bellows 1 interior air blast, powerful cold wind impacts by the blast cap 33 thermotropism sand on the boiling plate 31, make hot sand be in fluidized state, and hot sand blown toward sand export 7 directions, cooling water enters cooling water pipeline in the boiling-house 3 from water inlet 8, current and sand flow are reverse, the hot sand that is in fluidized state fully contacts in boiling-house 3 with the cooling water of the cold wind that blasts and adverse current, carry out heat exchange, hot sand is cooled off, and cooled sand material draws off from sand export 7, and cooling water then flows out by delivery port 9.

Diffuser casing 4 is wider spaces of sand grains boiling, when the dust in hot sand sucks deduster from dedusting outlet 5, sand grains can both not guarantee cooling and the dust removing effects of hot sand along with dust is inhaled into deduster together, has solved again that hot sand is siphoned away by deduster and the waste problem that causes.

Claims
