Description
Technical field
A kind of drying tower cone heating and cooling device belong to chemical liquid spray drying device field.
Background technology
The drying tower cone is the bottom at the bottom of the tower of drying tower; It is the visual plant that the workshop granular material is collected; Owing to directly pasting the cone inwall, descends material; The running quality and the product quality of the degree of drying of cone and the cooling protection degree direct influence tower in the production process need heat, cool off when producing when the baking tower for this reason.Workshop drying tower cone only adopts the type of cooling of middle part axial flow blower air-out, cone top and the bottom air intake at present.During cooling, draw natural wind from cone bottom and drying tower top by axial flow blower, the air draft from cone middle part, cooling slowly and poor effect and top air-admitting surface greater than the bottom air-admitting surface, intensity of cooling is not enough, has influenced product quality.Baking during tower air after the air heater heating, deliver in the drying tower and go downwards to the cone middle and upper part after return cone upper, annular road, after air-introduced machine is sent into main evacuated tube emptying through discharge pipe, the cone middle and lower part then mainly is to lean on the radiant heat heating, drying.Because the drying tower air outlet is on cone top, hot blast is difficult to arrive the cone middle and lower part, and the cone oven dry is slower, and thermal energy consumption is bigger.
Summary of the invention
The technical problem that the present invention solved is: it is slower with the cooling device oven dry to have overcome existing drying tower cone heating; Consumed power is bigger; Cooling effect is not good, influences the problem of product quality, provides a kind of drying tower cone more efficient, energy-conservation, good cooling results to heat and cooling device.
The technical scheme that technical solution problem of the present invention is adopted is: this heating of drying tower cone and cooling device; Chuck, main exhaust duct at the bottom of the awl that comprise the cone that is fixed in drying tower bottom, is set in the cone bottom; The air-introduced machine that connects the discharge pipe of main exhaust duct and drying tower and be installed in discharge pipe is characterized in that: the parallel beneath at discharge pipe is provided with a blast pipe, and blast pipe one end links to each other with awl end chuck; The other end connects main exhaust duct, and discharge pipe is connected through pipeline with blast pipe.
On the described blast pipe air blast is installed, is played the effect of air-supply.Between blast pipe and the main exhaust duct second control valve is set, between discharge pipe and the main exhaust duct first control valve is set, the 3rd control valve is set between discharge pipe and the blast pipe, can adjust air quantity size and circulation path through the switching of regulating each control valve.
Compared with prior art, the beneficial effect that the present invention had is:
1. energy-saving and cost-reducing, raising production capacity: because cone adopts the heating of drying tower self waste heat; And quote natural wind and cool off; Oven dry is obviously improved with cooling velocity, drying tower feed intake in advance operation, saved a large amount of electric energy and heat energy, prolonged the cycle of operation, the production capacity of raising drying tower;
2. effectively guaranteed product quality: the type of cooling cooling of air inducing middle part air-out is forced to cool off with air blast and is combined about the cone cooling employing axial flow blower, and good cooling results, cone are protected no longer overheated from bottom to top, have guaranteed the quality of product effectively.
Description of drawings
Fig. 1 is a kind of drying tower cone heating and cooling device structural representation.
Wherein: 1, cone 2, awl end chuck 3, blast pipe 4, air blast 5, second control valve 6, main exhaust duct 7, first control valve 8, the 3rd control valve 9, air-introduced machine 10, discharge pipe 11, drying tower.
Fig. 1 is a most preferred embodiment of the present invention, and 1 couple of the present invention further specifies below in conjunction with accompanying drawing:
The specific embodiment
With reference to accompanying drawing 1:
Chuck 2, main exhaust duct 6 at the bottom of the awl that this a kind of drying tower cone heating and cooling device comprise the cone 1 that is fixed in drying tower 11 bottoms, be set in cone 1 bottom; Connect main exhaust duct 6 and the discharge pipe 10 of drying tower 11 and the air-introduced machine 9 that is installed in discharge pipe 10; Parallel beneath at discharge pipe 10 is provided with a blast pipe 3, and blast pipe 3 one ends link to each other with awl end chuck 2, and the other end connects main exhaust duct 6; Discharge pipe 10 and blast pipe 3 are connected through pipeline, and main exhaust duct 6 is vertically placed.
The operation principle and the course of work are following:
The heating of this drying tower cone and cooling device have made full use of drying tower 11 self waste heat; Through air-introduced machine 9 and air blast 4 hot blast is introduced cone 1 bottom air inlet; Hot blast is directly pounced on the heating of cone 1 outer wall fast; During cooling, utilize air blast 4 that natural wind is introduced 3 pairs of cones 1 of blast pipe and force cooling, and keep the former axial flow blower type of cooling of air inducing middle part air-out up and down.
During cone 1 heating, first control valve 7 is in semi-closed state, second control valve 5 are closed fully, the 3rd control valve 8 is opened fully, the air quantity size is regulated by first control valve 7.Air delivers in the drying tower 11 after the air heater heating; The part hot blast is drawn by discharge pipe 10 through air-introduced machine 9 again; Be incorporated into blast pipe 3, blow to awl chuck 2 bottoms, the end to hot blast through air blast 4 work, and heat by the top discharge; This mode of heating and former mode of heating carry out simultaneously, have accelerated drying rate.During cone 1 cooling; First control valve 7 is opened to guarantee that production is carried out simultaneously, second control valve 5 is opened fully, the 3rd control valve 8 cuts out fully fully; And make air blast 4 work, and natural wind is introduced blast pipe 3 and fed awl end chuck 2 through main exhaust duct 6, it is forced cooling; The former axial flow blower type of cooling is carried out simultaneously, has accelerated cooling velocity.
The above only is preferred embodiment of the present invention, is not to be the restriction of the present invention being made other form, and any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But everyly do not break away from technical scheme content of the present invention, to any simple modification, equivalent variations and remodeling that above embodiment did, still belong to the protection domain of technical scheme of the present invention according to technical spirit of the present invention.
