Description

A kind of drying plant

Technical field

The utility model relates to a kind of drying plant, in particular for the drying plant of parched food.

Background technology

The old-fashioned roasted seeds and nuts drying pool of tradition adds hot-air by hot-blast stove and sends into drying pool bottom, the hot blast heating, drying melon seeds that make progress, and this baking pond heat scatters and disappears greatly, production cost height, effect instability.

Summary of the invention

The purpose of this utility model provides a kind of hot blast utilization rate height, simple in structure, maneuverable drying plant.

For achieving the above object, the utility model is by the following technical solutions:

A kind of drying plant described in the utility model comprises casing, in the inner chamber of casing, be provided with sieve plate, have sieve aperture on the sieve plate, the wall box of sieve plate below is provided with hot-air mouth, heat exchanger and air blast are installed on the hot-air mouth, it is characterized in that: be installed with a plurality of fixedly bushings in the cabinets cavity above sieve plate, the middle part of described fixedly bushing raises up, a plurality of fixedly bushings are parallel to each other and are provided with at interval, fixedly bushing side is provided with rotating shaft, the two ends of described rotating shaft are installed with movable bushing by interting on the sidewall of casing in the rotating shaft, rotating shaft is in transmission connection by transmission mechanism and drive unit.

Described transmission mechanism comprises the connecting lever that is fixedly connected in the rotating shaft, is hinged on the pull bar on the connecting lever, described drive unit is the piston apparatus that is connected on the pull bar, the pull bar that each hinged level of the two ends of piston apparatus is installed, respectively connect a connecting lever vertical with rotating shaft on the revolution axle, each connecting lever is hinged on the pull bar respectively.

Described piston apparatus is air rammer cylinder or hydraulic piston cylinder.

The cross section of described fixedly bushing is triangle or semicircular arc.

Described heat exchanger is a heat-condutive oil heat exchanger.

This dryer is changed to heat-condutive oil heat exchanger with traditional heat source, thermal efficiency height, temperature stabilization; On tradition baking pond, install the second layer additional, recycle the heat of the loss of lower floor, energy savings about 40%.

The specific embodiment

As shown in drawings, a kind of drying plant described in the utility model comprises casing 1, materials such as casing 1 employing corrosion resistant plate are made sidewall and base plate, in the inner chamber of casing 1, be provided with sieve plate 2, have sieve aperture on the sieve plate 2, weld together with the sidewall of casing 1 around the sieve plate 2, the inner chamber of casing 1 is divided into two parts up and down.The wall box of sieve plate 2 belows is provided with hot-air mouth, and heat exchanger 3 and air blast are installed on the hot-air mouth, and this heat exchanger 3 is a heat-condutive oil heat exchanger, can certainly adopt other forms of heat exchanger.For the ease of the maintenance and the maintenance of feeding and discharging and equipment, openable dodge gate can also be set in the appropriate location of casing 1.These all are the known technologies of this area, be not described in detail at this.

Be installed with a plurality of fixedly bushings 4 in casing 1 inner chamber above sieve plate 2, the middle part of described fixedly bushing 4 raises up, a plurality of fixedly bushings 4 are parallel to each other and are provided with at interval, fixedly bushing 4 side is provided with rotating shaft 5, the two ends of described rotating shaft 5 are by interting on the sidewall of casing 1, be installed with movable bushing 6 in the rotating shaft 5, rotating shaft 5 is in transmission connection by transmission mechanism and drive unit.Fixedly the gap between the bushing 4 is suitable for the width of movable bushing 6 and two, that is to say, just in time can fill up two fixedly gaps between the bushing 4 when movable bushing 6 is in level.Fixedly all be distributed with a plurality of breeder tubes on bushing 4 and the movable bushing 6, so that the hot-air of below upwards flows.

Described transmission mechanism comprises the connecting lever 51 that is fixedly connected in the rotating shaft 5, is hinged on the pull bar 52 on the connecting lever 51, described drive unit is the piston apparatus 53 that is connected on the pull bar 52, the pull bar 52 that each hinged level of the two ends of piston apparatus 53 is installed, respectively connect a connecting lever 51 vertical with rotating shaft on the revolution axle 5, each connecting lever 51 is hinged to respectively on the pull bar 52.Described piston apparatus 53 is air rammer cylinder or hydraulic piston cylinder.

In the present embodiment, fixedly the cross section of bushing 4 is a triangle, also can adopt the fixing bushing of semicircular arc as shown in Figure 4.

During use, at first handle drive unit, make movable bushing 6 be in level, put the materials such as roasted seeds and nuts that need oven dry into from charging aperture or casing 1, dry to hot-air mouth by opening air blast, enter in the inner chamber of sieve plate 2 belows through heat exchanger 3 later hot blasts, rise by the sieve on the sieve plate 2 is empty, again through the breeder tube on fixedly bushing 4 and the movable bushing 6 with material prebake.After prebake is arrived to a certain degree, can start drive unit, horizontal movement drive connecting lever 51 by pull bar 52 rotates a certain angle, thereby make rotating shaft 5 and be connected movable bushing 6 deflection certain angles in the rotating shaft 5, material on the movable bushing 6 is dropped on the fixedly bushing 4 of lower floor, continue oven dry.Movable bushing 6 restores puts material prebake later on on the upper strata.
