Problems solved by technology

[0002] At present, the domestic material interception device adopts a rigid sealing structure. Due to the ventilation effect of the breathable layer, the powdery material is cut off when it is fluidized, and the air continues to blow to the breathable layer. There is a gap between the breathable layer and the upper baffle, resulting in Material leakage is serious

Embodiment Construction

[0011] Such as figure 1 -shown in 4, comprising upper groove 1, lower groove 2 and material intercepting device 3, described upper groove 1 is a material groove, and lower groove 2 is an air groove, is provided with air-permeable layer 7 between upper groove 1 and lower groove 2 , A perforated plate 10 is also arranged above the air-permeable layer 7 .

[0012] The material intercepting device 3 includes a gate 4, a gate support frame 5 and a cylinder 6. The gate support frame 5 is placed on the upper end of the upper tank 1, and the gate 4 is installed in the gate support frame 5 so that it can move up and down. The cylinder 6 is used to drive the shutter 4 to move up and down to realize the opening and closing of the upper groove 1 .

[0013] The air-permeable layer 7 on the same vertical plane as the flashboard 4 is provided with a transverse through groove, the upper end surface of the through groove is covered with a rubber layer 8 , and the lower end surface of the thro...

Abstract

The invention discloses an air chute, relating to material conveying equipment. The air chute comprises an upper chute, a lower chute and a material cut-off device, wherein the upper chute is a trough, the lower chute is an air drain, a ventilation layer is arranged between the upper chute and the lower chute, the material cut-off device comprises a cut-off plate, a cut-off plate supporting frame and an air cylinder, the cut-off plate supporting frame is arranged at the upper end of the upper chute, the cut-off plate is arranged in the cut-off plate supporting frame in a vertical moving way, and the air cylinder is used for driving the cut-off plate to vertically move to open and close the upper chute; and a horizontal through chute is arranged on the ventilation layer on the same vertical plane with the cut-off plate, a rubber layer is covered on the upper end surface of the through chute, and the lower end surface of the through chute is provided with a baffle. The air chute is provided with the rubber layer and the baffle for double sealing, and flexible sealing and rigid sealing are combined, so that the leakage rate of products in a cut-off state is lower than 1%; and the air chute is simple in structure and lower in cost.

Description

technical field [0001] The invention relates to a material conveying device, specifically an air chute. Background technique [0002] At present, the domestic material interception device adopts a rigid sealing structure. Due to the ventilation effect of the breathable layer, the powdery material is cut off when it is fluidized, and the air continues to blow to the breathable layer. There is a gap between the breathable layer and the upper baffle, resulting in Material leakage is serious. Contents of the invention [0003] The object of the present invention is to provide an air chute, the air chute is provided with a material intercepting device with good sealing performance, and the material throttling device is simple in structure and low in price. [0004] The technical solution for achieving the above object is: an air chute, comprising an upper trough, a lower trough and a material intercepting device, the upper trough is a material trough, the lower trough is an ai...
