Description

Technical Field

[0001] The utility model relates to the technical field of grain dryers, in particular to a mixed-flow dryer with a grain escape prevention structure. Background Art

[0002] There are two main drying processes for batch grain dryers: cross-flow and mixed-flow. In mixed-flow drying processes, a horn-shaped box structure is usually used as the main structure in the drying layer.

[0003] The so-called corner box structure is actually a rectangular triangle with open ends. When multiple corner boxes are combined with the front and rear panels, they form a drying layer, half of which is the hot air inlet and the other half is the moisture outlet for the heated grain. The hot air blower can be placed at the hot air inlet (called a push-in type) or the moisture outlet (called a suction type).

[0004] Due to the pressure (positive pressure) and suction (negative pressure) of the fan, the grain will inevitably be affected during its movement in the drying layer. If the structural design is unreasonable, the grain will often be discharged from the dryer body under the influence of the fan, causing losses.

[0005] The problem of grain leakage from the angular box in the mixed flow dryer exists more or less in the current dryer manufacturing, and it is a difficult problem that must be solved in the mixed flow dryer manufacturing. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 2 , the utility model provides a technical solution:

[0023] A mixed flow dryer with a grain escape prevention structure, comprising:

[0024] A angular box is provided in the mixed flow dryer 1, which includes an air inlet angular box and an air outlet angular box 2. The air inlet angular box and the air outlet angular box 2 are staggered and arranged opposite to each other in the mixed flow dryer 1, so that on two opposite surfaces of the mixed flow dryer 1, one surface is the air inlet of the air inlet angular box, and the opposite surface is the air outlet 3 of the air outlet angular box 2.

[0025] The air outlet 3 of the air outlet horn box 2 is provided with an horn box baffle.

[0026] The angular box baffle includes a fixed bottom plate 6, a fixed hole 7, a leak-proof plate 4 and a side baffle 5. The fixed hole 7 is opened on the fixed bottom plate 6. The fixed hole 7 is opened on the fixed bottom plate 6. The fixed hole 7 is symmetrically opened on the fixed bottom plate 6. Several fixed holes 7 can be reasonably selected according to the size of the air outlet 3 of the air outlet angular box 2. The leak-proof plate 4 is set on the fixed bottom plate 6. The leak-proof plate 4 is fixedly connected to the fixed bottom plate 6 by welding or the like. The leak-proof plate 4 is tilted on the fixed bottom plate 6. By tilting the leak-proof plate 4, it does not affect the air outlet. The angle box 2 discharges moisture and prevents grain from escaping. The side baffle 5 is arranged on the leak-proof plate 4. There are two side baffles 5, which are respectively arranged on both sides of the leak-proof plate 4. The side baffle 5 is fixed to the leak-proof plate 4 by welding or the like. During installation, the fixing holes 7 on the fixed base plate 6 are aligned with the mounting holes of the air outlet angle box 2. Bolts are inserted into the fixing holes 7 and the mounting holes. While connecting the air outlet 3 of the angle box baffle and the air outlet angle box 2, the angle box baffle and the air outlet angle box 2 are installed on the mixed flow dryer 1.

[0027] Angular half boxes 8 are provided on both sides of the mixed flow dryer 1. The shape of the angular half boxes 8 is the shape of the air outlet angular box 2 cut along the symmetry plane. The angular half boxes 8 are also provided with angular box baffles, which are smaller in size than the angular box baffles on the air outlet angular box 2. There are 16 air inlet angular boxes, 12 air outlet angular boxes 2, and 8 angular half boxes 8.

[0028] Working principle: When in use, dry hot air is introduced into the air inlet angle box, so that the hot air enters the mixed flow dryer 1 to dry the grain, and the moisture in the grain enters the air outlet angle box 2 along with the air flow, and the moisture is discharged through the air outlet angle box 2. By setting the angle box baffle at the air outlet 3 of the air outlet angle box 2, the leak-proof plate 4 and the side baffle 5 surround the air outlet 3 of the air outlet angle box 2 to prevent the grain from being blown out of the mixed flow dryer 1 when the moisture is discharged.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
