Abstract
The utility model relates to a regulating valve for hot and cold wind in a drying apparatus for cereal, mainly composed of an electric motor, a gear wheel, gear racks, and inside and outside valve pipes which exist in the same shaft. The vent holes of the inside and outside valve pipes are mutually dislocated and sheathed. During using, the optimal mixing of the hot and cold wind in optimum temperature which is required for drying cereal can be obtained when the sizes of the axial vent holes (namely hot wind can enter) and the radial vent holes (namely cold wind can enter) are regulated. The utility model has the advantages of reasonable design, and simple structure. The effect of wind distributing is good.
Description
Relate to a kind of valve, a kind of cold and hot wind modulating valve in the particularly relevant grain-drying equipment.
Cereal must remove moisture content before storage.Method one commonly used is that nature teds, and another is artificial drying-promptly use drying plant to evaporate its moisture content.How this method blows the hot blast of uniform temperature and takes away its contained moisture content with this to cereal with a covering device.In order to control the temperature that blows hot blast, generally use valve to regulate.Existing a kind of butterfly valve, because of it mainly is to utilize to reduce the airduct caliber and reach the temperature control purpose, this valve is owed rationally easily to produce the blower fan flutter and influence total blast volume because of its structure.For this reason, the purpose of this utility model is to overcome aforesaid defective and design a kind of adjusting respond well valve of air distribution freely.
This valve mainly contains formations such as inside and outside valve pipe, motor, axle, gear, tooth bar and tailstock.Inside and outside valve pipe has been the end and has been nested with mutually and totally one, is the temperature of regulating air-supply, the axle of inside and outside valve pipe, radially all has the hole, also promptly in upward perforate of pipe bottom surface (axially) tube wall (radially).Wherein, the outer tube bottom surface equates with the number of aperture of its tube wall and is cophasing that the hole count with its wall at the bottom of the interior pipe should be equal to the phase angle but the hole of the Kong Yuqi bottom surface on the tube wall interlaces with the outer tube hole count.Two the pipe bottom center porose and place its end support in cross tailstock axis hole the axle.Said cross tailstock is the part in addition that is shaped on four bars or sheet support outside a guide pipe or bushed bearing admittedly, and the outer end of four supports of this cross tailstock is individually fixed in the inwall of outer valve pipe.In like manner, for making internal valve pipe stable rotation on axle, its internal valve pipe beginning inwall is fixed with the interior cross tailstock that passes axle.For inside and outside valve pipe is relatively rotated, in that it axially installs a motor near the outer valve pipe outer wall upper edge at the pipe end, this machine output terminal is put a gear that is meshed with a tooth bar, and this tooth bar passes on the outer valve tube wall at the groove of its relevant position and is fixed on the internal valve tube wall.During use, this valve joins with its bottom and warm-air pipe, and then hot blast enters in the pipe through the hole of pipe bottom surface, and the hole on the tube wall communicates with atmosphere.When needing the hot blast of different temperatures, can handle motor rotation tooth bar rotates the internal valve pipe, or open (closing) pipe end the hot blast through hole time or close cold wind through hole on (opening) tube wall, regulate the purpose that cold and hot wind mixes appropriateness to reach the oven dry desired temperature of cereal.
The utility model is reasonable in design, and is simple in structure, easy to use and air distribution is respond well.As use reversible motor and temperature sensing device can realize the automatic control that air quantity is constant.
For realizing above-mentioned design, a kind of preferable scheme is proposed in conjunction with the accompanying drawings.Fig. 1 is this valve vertical section structure schematic representation, welds after outer valve pipe 1 usefulness roll of steel plate is made D812 * 800MM, L1000MM, wherein manages the bottom surface towards six fan shaped boreholes are arranged, and tube wall dashes six rectangular openings.In like manner, internal valve pipe 11 is also by the pipe that is processed into D804 * 800MM, L896MM on the method, and the hole of the relative bottom surface, hole on its tube wall is staggered 60 °.Inside and outside cross tailstock all can constitute with four sheets supports of pipe fitting welding that axle is done movingly with one section, rivets it with inside and outside valve inner tube wall respectively behind its outer end flanging.Axle passes the inside and outside valve Guan Houqi tail end pin pinning that is nested with.Motor is selected the reversible model of JW6324 for use and is fixed on the outer valve pipe outer wall with screw, passes the outer effective screw of holding groove in advance successfully with the tooth bar of gear engagement and is fixed in the internal valve tube wall.During use, getting final product of connecing twisted through screw and warm-air pipe in the outer of valve pipe bottom surface in addition.Each title is as follows in the accompanying drawing, and Fig. 2 is that A is to view.
The outer valve pipe 2--tooth bar of 1--
3--gear 4--motor
The outer cross tailstock 6--axle of 5--
Pipe vent hole in the 7--outer tube fan shaped borehole 8--
Cross tailstock in the 9--outer tube vent hole 10--
Pipe fan shaped borehole in the 11--internal valve pipe 12--
Claims (2)
1, relates to a kind of cold and hot wind modulating valve in the grain-drying equipment, comprise inside and outside valve pipe, motor, axle, gear and a tooth bar and a tailstock etc., it is characterized in that managing inside and outside valve pipe that the end and tube wall all have vent hole and be nested with and totally one, equate and cophasing with the number of tube wall perforate at the bottom of its outer valve pipe, should be equal to mutually with the former with the number of aperture of tube wall at the bottom of the internal valve pipe but should wrong mutually phase angle, the motor that its output terminal is equipped with gear is fixed in outer valve tube wall vertically, passes the outer valve pipe that circumferentially has groove with the tooth bar of gear engagement and is fixed in the internal valve tube wall.
2, modulating valve as claimed in claim 1, the inwall at outer valve pipe beginning is fixed in the outer end that it is characterized in that being used for the outer cross tailstock of back shaft, and internal valve pipe beginning inwall is fixed the interior cross tailstock that axle is passed at its center.
