Description

Air conveying chute with improved structure Technical Field The utility model belongs to the technical field of air conveying chutes, and particularly relates to an air conveying chute with an improved structure. Background The air conveying chute is a special equipment for conveying easily fluidized powdery materials such as cement, fly ash and the like, and generally uses a high-pressure centrifugal fan as a power source to enable the materials in the closed air conveying chute to slowly flow towards an inclined end under fluidization. The working principle is that the kinetic energy of the air flow is utilized to enable the particulate materials to be in a suspension state and conveyed along the pipeline along with the air flow. The air conveying chute generally comprises an upper shell, a lower shell and a ventilation layer arranged between the upper shell and the lower shell, and the existing air conveying chute is clamped at the connecting position of the upper shell and the lower shell due to the fact that the strength of the ventilation layer is insufficient, powder materials can be attached to the ventilation layer frequently in the conveying process, the powder materials are more tired, the middle of the ventilation layer is stressed excessively due to the gravity effect of the powder materials, if the powder materials accumulate for a long time, the ventilation layer with a platy structure is cracked from the middle, so that the powder materials infiltrate into the lower shell, and great inconvenience is brought to conveying operation. The above problems are particularly evident in the case of fly ash materials. Disclosure of utility model (1) Technical problem to be solved Aiming at the defects of the prior art, the utility model aims to provide an air conveying chute with an improved structure, which aims to solve the technical problems that the gravity action of powdery materials in the prior art often causes the middle part of a breathable layer to be stressed too much, and the breathable layer with a platy structure is easy to split from the middle part, so that the powdery materials infiltrate into a lower shell, and the conveying operation is greatly disadvantageous. (2) Technical proposal In order to solve the technical problems, the utility model provides the air conveying chute with the improved structure, which comprises an upper shell, a lower shell and a ventilation layer detachably fixed at the bottom end of the upper shell, wherein second protruding parts are fixed at two sides of the inner wall of the lower shell, second connecting plates are fixed at two ends of the lower shell, a positioning plate is fixed between the two second protruding parts, holding grooves are formed in the top ends of the two second connecting plates at equal intervals, a supporting plate for supporting the ventilation layer is detachably fixed in the holding grooves at the same side, and rib plates are fixed at two sides of the bottom end surface of the supporting plate. When the technical scheme is used, the ventilation layer is arranged between the upper shell and the lower shell, the first protruding part and the second protruding part are respectively and tightly connected with the upper side and the lower side of the ventilation layer, meanwhile, the mounting plates at the two ends of the ventilation layer are fixed with the positioning plates through the mounting bolts, the ventilation layer is kept fixed between the upper shell and the lower shell, the support plates used for supporting the ventilation layer are detachably fixed in the accommodating grooves at the top ends of the second connecting plates, the ventilation layer is supported by the support plates, the strength of the ventilation layer is improved, the situation that the ventilation layer is stressed too much and breaks is reduced, the rib plates are fixed at the bottom ends of the support plates, the strength of the support plates is improved, meanwhile, the support plates are kept stable through the through holes when the first connecting plates and the second connecting plates are fixed, the support plates are enabled to slide and detach from the accommodating grooves through the protruding plates after the connecting bolts are detached, the support plates can be detached and detached from the support plates only, and the support plates can be detached and replaced only by the connecting bolts at the two sides of the support plates, and convenience of the support plate detachment and replacement is improved. Preferably, the two ends of the upper shell and the lower shell are both fixed with mounting parts, and a plurality of mounting holes are formed in the mounting parts. Further, the bottom end face both sides of going up the casing all are fixed with first connecting plate, the through-hole that runs through backup pad and second connecting plate has been seted up to the top equidistance of first connecting plate.
