Abstract

The utility model provides a grain dryer based on a conveying belt, aiming at solving the problems that the existing grain crop drying equipment is large in volume, inconvenient to move, high in investment cost and the like. The structure of the conveying belt type grain dryer consists of two stages of drying layers with the same structure. The drying layers convey the grain by the conveying belt, and the moving speed of the conveying belt can be adjusted according to the humidity of the grain, so that the conveying belt type grain dryer can solve the problem that the drying time of the existing drying equipment can not be adjusted. The conveying belt type grain dryer evenly spreads out the grain by a grain spreading device when in use, wherein the depth of the grain is even. When the conveying belt type grain dryer is in use, the hot wind which is blown from an airheater enters into the drying layers from the lower side of the dryer, and the moist steam is absorbed by the upper side of the dryer. The furnace smoke which is generated by burning the airheater also enters into the drying layers to greatly reduce the energy loss. The conveying belt type grain dryer is good in drying effect, simple in structure, convenient to move, high in efficiency, and low in investment.

Description

A kind of conveyor type grain drier
Technical field
The utility model relates to a kind of automatic equipment that grain is carried out flash baking, belongs to the grain drying technical field.
Background technology
The grain drying of China also mainly relies on the daylight airing, and grain is put on the ground, dries with daylight.If run into rainy weather, grain go mouldy the loss very big, cause tremendous loss to national food production and processing, particularly current people in the countryside shift to the city, and the daylight airing needs a large amount of labours and time, so only depend on daylight airing grain to become unrealistic gradually.Mechanical type drying machine oven dry grain is not subjected to the restriction of weather condition, but the current equipment volume that is used for grain heat-drying is big, is difficult for assembling and moves, and the equipment manufacturing cost height; Grain need fall to drying by deadweight, though adopt hot blast from countercurrent heat exchange principle from bottom to top, energy is not well utilized; The drying time of grain is uncontrollable, causes the very big wasting of resources even causes destroying the nutritional labeling of grain.
Summary of the invention
At the shortcoming that above-mentioned prior art exists, the experience of this area work is engaged in inventor's accumulation for many years, through feasibility study repeatedly, gets generation of the present utility model eventually, and the utility model provides a kind of conveyor type grain drier.
The technical scheme that its technical problem that solves the utility model adopts is as follows: a kind of conveyor type grain drier mainly comprises first order drying layer, second level drying layer.Its described first order drying layer be installed in second level drying layer above, each the layer between separate with dividing plate.In the installed inside of dividing plate the highly identical grain device of taking off is arranged, each takes off between the grain device evenly distributed, and the steel wire conveyer belt is installed below taking off the grain device, and the steel wire conveyer belt is wrapped on the belt wheel, the many holder rods that diameter is identical are installed below the steel wire conveyer belt, and the holder rod is mainly used to the supporting steel wire conveyer belt.
First order drying layer all adopts identical layout with second level drying layer, conveyer belt translational speed in the drying layer is identical, translational speed can be regulated according to the humidity of current grain, can regulate drying time by changing the conveyer belt translational speed, can guarantee the grain homogeneous heating, to reach the drying requirement of grain.Steel wire conveyer belt in the drying layer is made up of the steel wire that can let in air.
Operation principle of the present utility model is: after wet grain crop enters into silo by transmission pipeline, enter in the first order drying layer, and fall on the steel wire conveyer belt of conveyer, grain moves along with conveyer belt moves slowly, grain on the steel wire conveyer belt spreads out thickness and is controlled by the grain device of taking off that is installed on the dividing plate, and take off the grain device and equate from belt heights, be even at drying course thickness in order to guarantee grain, take off the grain device simultaneously and can make grain upset in moving, grain is evenly heated.Wherein the hot blast that blows out from hot-blast stove blows into first order drying layer and the second level drying layer through the hot blast import, and the moisture of extracting out at the upside of drying layer is discharged by hot-blast outlet simultaneously, and each grade drying layer all has a hot blast import and hot-blast outlet.The hot blast import all is placed in the left side of the below of drying layer, and hot-blast outlet is located at the right side of drying layer top, and arrangement can make the interior temperature of drying layer present certain gradient like this.In first order drying layer, from left to right temperature for from height to low variation of successively decreasing, grain enters the drying layer cereal temperature and raises gradually, grain has just begun to enter drying and is unlikely to bear excessive temperature and causes the grain explosion like this.In the drying layer of the second level, present from height to low variation from passage to the temperature of putting out cereal mouthful of putting out cereal of first order drying layer, guarantee that grain temperature when putting out cereal lowers.In order to improve rate of energy, will also enter drying layer from the cigarette that hot-blast stove is discharged by tobacco transmission pipe, the stove cigarette enters stove smoke pipe road through the import of stove cigarette, and aluminium alloy material stove smoke pipe road is provided with many stove smoke pipe roads altogether.Leave the gap between each pipeline, help the circulation of hot blast like this.The whole passage of the turnover drying layer of stove cigarette all is totally enclosed, does not contact with wet grain, and the heat of stove cigarette improves the temperature of drying layer with temperature difference transmission form.Because wet grain only can not reach dry effect through one deck drying layer, the present invention is provided with second level drying layer.Grain enters second level drying layer conveyer belt by the passage of putting out cereal after drying from the ground floor drying layer.The frame for movement of second level drying layer is identical with the first order, and its effect is for to the further precipitation drying of grain, improves the precipitation rate of grain.Grain is after mouthful discharge of putting out cereal.Mobile wheel can the convenient and dry machine move.
The purpose of this utility model is in order to alleviate the problem of above-mentioned existence, to save the energy as much as possible, increase the rate of drying of grain, improve working (machining) efficiency, reducing floor space and equipment cost.It has simple in structure, energy utilization rate is high, drying is effective, can be widely used in the drying of all kinds of graininess crops, has vast market prospect.Reinforcement will effectively promote the update and the production development of product to the research and development of grain drier, to further increasing economic efficiency, improves existing production technology level, and very important practical sense is arranged.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is this utility structure simplified schematic diagram.
Description of reference numerals: 1, hot blast import 2, hot-blast stove cigarette import 3, the passage 4 of putting out cereal, steel wire conveyer belt 5, take off grain device 6, holder rod 7, stove cigarette channel 8, hot-blast outlet 9, advance silo 10, hot-blast stove cigarette outlet 11, belt wheel 12, first order drying layer 13, supporting steel plate 14, second level drying layer 15, put out cereal mouthfuls 16, move wheel 17, stove smoke pipe road.
The specific embodiment
