Detailed Description
The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.
As shown in fig. 1, the invention discloses a rolling blind wind-closing device, which is characterized in that: the roller shutter air-blocking device comprises an air-blocking shutter 1, a scroll 2, a gravity shaft 3, a motor reducer 4, a material level position detection device 5, an air-blocking shutter position detection device 6 and a small reel 8; the roller shutter air-blocking device is arranged at a hot air inlet of the dryer, an air-blocking plate 7 is arranged at a position, needing wind shielding, of an air inlet at the upper end of the drying section, a plurality of observation windows 10 are arranged on the drying section to observe the height of a grain layer, a plane is added to the original part at the front end of the air inlet, air inlet holes are formed in the positions, corresponding to the air inlet channels, of the plane, a partition plate is arranged between every two adjacent rows of air inlet holes horizontally, and airflow cannot be formed; one end of an air-tight curtain 1 is fixed at the upper part of an air inlet of a drying section, the other end of the air-tight curtain 1 is fixed on a scroll 2, a gravity shaft 3 is placed on the air-tight curtain between a fixed end and the scroll, the gravity shaft 3 falls down to enable the air-tight curtain to be in a U shape, the scroll 2 is fixed on the inner side of the top of a front fan cover through a bearing, one end of the scroll 2 is connected with a motor reducer 4, a small reel 8 is installed at the other end, a string is wound on the small reel 8, a heavy object 9 is hung at the lower end of the string, the position of the heavy object 9 always keeps the same height with the gravity shaft to be used as a gravity shaft position indication mark, and limiting devices 11 are installed at the.
The working principle of the roller shutter air-blocking device is as follows: the reel 2 is driven to rotate forward and backward through the motor to achieve the purposes of folding and unfolding the closed air curtain 1, the upper position and the lower position of the gravity shaft 3 are changed, the gravity shaft 3 plays a tensioning role for the closed air curtain 1 through self weight and enables the closed air curtain 1 to be flat, the closed air curtain 1 is tightly attached to an air inlet hole under the pressure of air, and therefore the effect of isolating hot air is achieved, the purpose of efficiently utilizing hot air is achieved, and the loss of heat energy is avoided.
