Detailed description of the invention
The invention provides a kind of particle drying equipment, improve the efficiency of particle drying.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on embodiments of the invention, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope of protection of the invention.
Please refer to Fig. 2, the structure rough schematic view of a kind of particle drying equipment that Fig. 2 provides for the embodiment of the present invention.
Embodiments provide a kind of particle drying equipment, as shown in Figure 2, comprising: dry cylindrical shell 11, the antetheca 111 of dry cylindrical shell 11 offers blowing mouth 112; Radiating tube 12, it is inner that radiating tube 12 is arranged on dry cylindrical shell 11; High temperature tracheae 14, it is outside that high temperature tracheae 14 is arranged on dry cylindrical shell 11, and be communicated with radiating tube 12; Air blast 16, number is at least one; Ventilation duct 13, the number of ventilation duct 13 is identical with the number of air blast 16, and each ventilation duct 13 correspondence connects an air blast 16, and is communicated with the blowing mouth 112 of respective number, forms at least one air blasting passage; Heater 15, heater 15 is arranged at least one ventilation duct 13, and is communicated with this ventilation duct 13.
The course of work of the particle drying equipment that the embodiment of the present invention provides is: it is inner that wood shavings enter dry cylindrical shell 11, high temperature tracheae 14 passes into high-temperature gas to radiating tube 12, radiating tube 12 generates heat and to dry cylindrical shell 11 internal heat dissipating, meanwhile, wood shavings with the rotation of dry cylindrical shell 11 at dry cylindrical shell 11 interior overturn, wood shavings constantly and radiating tube 12 and hot air, and then realize the drying of wood shavings, on the basis of this drying effect, from air blast 16 air out, heater 15 was flowed through before entering dry cylindrical shell 11, air is heated, enter dry cylindrical shell 11 afterwards, improve the temperature in dry cylindrical shell 11 further, thus improve the drying efficiency of wood shavings, through being compared with the prior art, find under identical pressure condition, temperature in dry cylindrical shell 11 is than front improve general 15 DEG C, and ensureing on the basis that wood shavings water content meets the demands, drying efficiency improves general 25%, and then improve the working (machining) efficiency of particieboard.
Embodiments provide a kind of concrete heater 15, heater 15 is heating clamber, and heating clamber is arranged on the air ventilation passage of ventilation duct 13, must through heating clamber when air flows through ventilation duct 13, and heating chamber is provided with high temperature tracheae 14; During work, the air in air blast 16, after ventilation duct 13 enters heating clamber, is heated by the heat that the high temperature tracheae 14 in heating clamber distributes, and enters in dry cylindrical shell 11 by ventilation duct 13, improves dry cylindrical shell 11 internal temperature, realizes the raising of drying efficiency.
In order to ensure the exothermic temperature of the high temperature tracheae 14 in radiating tube 12 and heating clamber, the high temperature tracheae 14 be communicated with radiating tube 12 arranges valve, and object controls the pressure in radiating tube 12 and high temperature tracheae 14, when pressure reaches 6KPa-8KPa, valve open, release high-temperature gas.
Arrange except the mode of high temperature tracheae 14 except adopting in heating clamber, heating clamber can also be set to the chamber with sandwich, such as, the locular wall of heating clamber is double-decker, high temperature tracheae is communicated with interlayer, high-temperature gas is passed in interlayer, by interlayer to heating clamber distribute heat, thus the air heat that will flow through.
Heater 15 in the embodiment of the present invention or employing electric heater unit, the pipe that electric heater unit can be arranged on ventilation duct 13 is inner, or ventilation duct 13 runs through in electric heater unit, and is communicated with it, heating after electric heater unit energising, thus by the air heat of process.
Except adopting above heater 15, other device that can realize air function in heating ventilation pipe 13 all belongs to protection scope of the present invention, is not specifically limited at this.
In the present invention's specific embodiment, the number of air blast 16, ventilation duct 13 and blowing mouth 112 is two, each air blast 16 is communicated with a blowing mouth 112 by a ventilation duct 13, form two air blasting passage, and a heater 15 is arranged in any one in two ventilation ducts 13; Not only increase drying efficiency like this, dried in dry cylindrical shell 11 by two air blasts 16 simultaneously, make dry wood shavings can be blowed to the exit of dry cylindrical shell 11 in time by the air flowed, be beneficial to the carrying out of next step operation.
Certainly, the number of the air blasting passage formed by air blast 16 can be one or more, for multiple air blasting passage, only can arrange heater 15 in wherein one, also can arrange heater 15 on multiple air blasting passage, specific design requires to determine according to actual production.
The position of blowing mouth 112 is optimized, blowing mouth 112 is arranged on the peripheral part of the antetheca 111 of dry cylindrical shell 11, object is the probability being blown dry cylindrical shell 11 in order to reduce not dried wood shavings, simultaneously, at the more convenient layout blowing mouth 112 of the peripheral part of antetheca 111, not easily interfere with other pipeline.
The embodiment of the present invention is optimized ventilation duct 13, two port ones 31 be connected with heater 15 on ventilation duct 13 are set to horn mouth, bell-mouthed larger one end is connected with heater 15, namely before air flows through heater, the caliber of ventilation duct 13 increases gradually, to reduce the flow velocity of air, ensure that the air flowing through heater 15 has the longer heat time, when being flowed out heater 15 by the air heated, caliber reduces gradually, to increase the flow velocity of air, the air entered in dry cylindrical shell 11 is made to have larger speed, conveniently wood shavings are blown out dry cylindrical shell, be non-circular ventilation duct 13 for cross section, then comparatively large near the sectional area of one end of heater on ventilation duct 13, the object reducing wind speed and increase wind speed can be realized equally.
High temperature tracheae 14 in the embodiment of the present invention adopts steam pipe, logical high-temperature steam in steam pipe, and steam resource is commonplace, is easy to get; Certainly, can also be other high-temperature gas.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
