Louver-type air and material separating device

Abstract

The invention relates to a louver-type air and material separating device. The louver-type air and material separating device comprises guiding plates, louver blades, louver supporting plates, reinforcing ribs, a shell, upper blocking plates and lower blocking plates; the louver blades are fixed onto the louver supporting plates in an overlapped mode, certain gaps are reserved between the louver blades, the corresponding louver blades are combined to form each separating plate, and the separating plates are symmetrically installed to separate grain channels, cold air channels and hot air channels; the upper ends of the separating plates match the upper blocking plates to form ventilation openings similar to louvers so that grains cannot enter the cold air channels from the upper ends of the louvers; and the lower ends of the separating plates match the lower blocking plates, and are connected with the shell. The technical effects which can be achieved are as follows: the manufacturing cost is reduced; ventilation areas of the separating plates are increased; the louver-type air and material separating device is suitable for drying multiple types of grains, and thus has universality; and a better impurity removal effect can be achieved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a louver-type wind material separation device. Background technique [0002] A large number of existing grain dryers use the cross-flow drying process. The grain dryers using this process are mature and simple in technology, and the overall manufacturing difficulty is low, and the production cost is low. The hot air in the drying section of the dryer using this process is separated from the grain by using a sieve plate for isolation. The grain passes through the gap formed by the two sieve plates to form a grain layer, and the hot air flows into the grain layer from the hole of a sieve plate; After passing through the grain layer, it flows out from the hole of another sieve plate; this kind of sieve plate has the following disadvantages: 1. It is difficult to manufacture and the manufacturing cost is high; 2. In order to ensure the strength of the sieve plate, the opening ar...
