Description

Material vehicle for tunnel type hot air drying

Technical Field

The utility model belongs to the material drying field, concretely relates to a material car for tunnel type hot air drying.

Background

Tunnel type hot air drying is a common drying mode, and the working principle is as follows: the fan sends the air into the heater heating, and the hot-blast quilt input tunnel after the heating, and hot-blast temperature that can improve the material is with higher speed the evaporation of water in the material, and simultaneously, the vapor around the material is taken away by hot-blast to reach the purpose of dry material. In order to facilitate the transportation of materials, the tunnel type hot air drying generally loads the materials by using a trolley provided with a material tray, but due to the blocking of the trolley and the material tray, the air speed of hot air is rapidly reduced after the hot air enters the trolley. In addition, as shown in fig. 1, air has the property of fluid viscosity, when the hot air drying tunnel works, air on the lee side of the trolley cannot be supplemented completely, so that tail air is relatively thin, negative pressure is generated, and vortex is formed. Due to the reasons, the traditional tunnel type hot air dryer has the advantages that the wind speed of the center of the tunnel is low, the wind speed of the edge of the inner wall of the tunnel is high, hot air does not fully contact with materials and then passes through the tunnel to run off, so that the drying energy consumption is improved, the efficiency is reduced, and the drying is not uniform.

According to the Coanda Effect (Coanda Effect) in fluid mechanics, also known as Coanda Effect or Coanda Effect, the gas flow has a tendency to flow along the surface of a convex object instead of deviating from the original flow direction, and at the same time, according to the bernoulli principle in fluid mechanics, the reduction of the flow velocity causes the fluid to be adsorbed on the surface of the object to flow. I.e., there is a tendency for the convex surface to adsorb if a smoothly flowing fluid passes over the convex surface having a curvature.

In addition, the tray in the existing material trolley is divided into a fixed type tray and a pull type tray, and the two types of trays are not convenient enough for blanking.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in the figure, a material car for tunnel type hot air drying, including the outer cover body 1 that can ventilate, the articulated door body 2 of the front end of the outer cover body 1, door body 2 surface is the plane, the rear end surface of the outer cover body 1 is convex arc surface outwards, a plurality of framework 3 of the internal top-down horizontal sliding connection of outer cover, the outer cover body is publicly known structure with the sliding connection structure of framework 3, set up tray 4 on the framework 3, the front end sliding fit dead lever 5 of framework 3, the rear end and the framework 3 of tray 4 rotate to be connected, the front end of tray 4 sets up couple 400, couple 400 catches on dead lever 5.

As the utility model discloses an optimize structure: the front upper end of the frame body 3 is provided with two sides with sliding grooves 300, and two ends of the fixed rod 5 are in sliding fit with the sliding grooves 300. The above structure allows the fixing lever 5 to slide.

As the utility model discloses an optimize structure: the tray 4 is in a grid shape, and the grid structure is favorable for ventilation.

As the utility model discloses an optimize structure: the tray 4 is a V-shaped structure, and the V-shaped structure is favorable for conducting and reflecting wind, so that the contact area of the material and the wind is larger.

As the utility model discloses an optimize structure: the rear end both sides of tray 4 set up the minor axis, and the shaft hole is seted up to the both sides of framework 3, and the minor axis inserts shaft hole normal running fit, during the unloading, takes framework 3 out earlier, then lifts the couple 400 of tray 4 front end, makes couple 400 break away from dead lever 5, promotes dead lever 5 forward again, and dead lever 5 just can't block tray 4 like this, and tray 4 can rotate downwards smoothly, makes the material pour out smoothly. The advantage of design like this lies in, and convenient to use need not independent dismouting, tray 4 during the unloading.

As the utility model discloses an optimize structure: the dustcoat body 1 includes the skeleton and sets up the screen panel on the skeleton, it is concrete, the skeleton is the cuboid structure generally, the top of skeleton and the rear end of bottom are circular-arcly, the screen panel covers skeleton fretwork part, sliding fit is realized through the shape that matches to framework 3 and skeleton, specifically be there are four crossbeams respectively from top to bottom in the both sides side of skeleton, distance between two adjacent crossbeams about highly coincide with framework 3, control the minimum distance between two mated crossbeams and be less than framework 3's width, it inlays in the rectangle space that four crossbeams enclose to be equivalent to framework 3, framework 3 can be along the crossbeam back-and-forth movement, and can not fall down.

As the utility model discloses an optimize structure: the bottom of the outer cover body 1 is provided with a plurality of universal wheels 6.

During the use, will the utility model discloses a during material car D pushed tunnel type hot air dryer, each material car D blows in the direction in tunnel towards fan B at a distance of 3 ~ 5m, material car D's arc surface. The distance and the placing direction between each material vehicle D are ensured, hot air passes through the arc surface of each material vehicle D, compared with the traditional rectangular surface material vehicle, the loss of hot air is greatly reduced, more hot air remains passing through the arc surface, the distance between the material vehicles is 3-5 m, the former bout of slightly lost hot air energy is converged with the latter bout of newly supplied air, the hot air heat and wind power supplement is realized, the moisture content is reduced, and the full preparation is made for the drying of the next material vehicle D.

When the hot air drying operation is carried out, the flat surface of the material trolley D faces hot air, and the arc-shaped surface faces back to the hot air.
