Technical Field

The invention relates to a spray dryer, in particular to a rotary air electric heater cover.

Background

A spray dryer is a device that can accomplish both drying and granulation. The pressure, flow and spray hole size of the feed liquid pump can be adjusted according to the technological requirements, and the required spherical particles with a certain size proportion are obtained.

The existing small-sized spray dryer is provided with a heater cover, a heating pipe is arranged in the small-sized spray dryer, the heating pipe is used for heating air, and the heated air moves upwards to perform corresponding drying.

However, since the air is directly upward after entering, the heating time is short, the air is not hot enough, and the drying time is long.

The invention mainly provides a rotary air electric heater cover, which is used for solving the technical problems that the heating time is short because air enters and then directly faces upwards, the air heat is insufficient, and the drying time is longer in the prior art.

The technical scheme adopted by the invention for solving the technical problems is as follows: the rotary air electric heater cover comprises a stainless steel pipe cover, wherein an obliquely inserted air inlet pipe is arranged on one side of the stainless steel pipe cover;

the inner wall of the stainless steel pipe cover is detachably connected with the inner cylinder, and the upper end of the inner cylinder is welded with the upper end of the inner wall of the stainless steel pipe cover;

the stainless steel pipe cover inner wall below is equipped with the fixed disk, fixed disk bolted connection heater, the heater upper end extends to in the inner tube.

Furthermore, the inclined-insertion type air inlet pipe and the stainless steel pipe cover form an included angle of 15-75 degrees, and the inclined-insertion type air inlet pipe inclines downwards by 5-15 degrees.

Further, the inner cylinder is made of stainless steel, and the distance between the inner cylinder and the inner wall of the stainless steel pipe cover is 1cm-5 cm.

Further, the inner cylinder is formed by combining a cylindrical pipeline and a funnel-shaped pipeline, the funnel-shaped pipeline penetrates through the middle of the upper end of the stainless steel pipe cover, and the connecting position is welded and connected.

Further, the heater includes that the plastics dish spare passes through the bolt and can dismantle the connection the fixed disk, plastics dish upper end symmetry is equipped with two heating pipes, two with the heating pipe all is the setting of type "U" style of calligraphy, and two the heating pipe is alternately and is the setting of type "cross".

Furthermore, the stainless steel pipe cover can be dismantled and connect the guide pipe, the guide pipe is the type 90 setting of bending, guide pipe one end welded fastening connecting piece.

Compared with the prior art, the invention has the beneficial effects that:

the invention realizes corresponding rotary air inlet by obliquely connecting the obliquely inserted air inlet pipe with the stainless steel pipe cover, then, the inner cylinder is arranged in the stainless steel pipe cover, the heater heats the inner cylinder when heating air, the preheating of the air is realized by utilizing the heat conductivity of metal, and then the air moves upwards after reaching the bottom, thereby realizing the preheating of the air and the temperature rise under the action of the heater with the same power, further increasing the utilization rate of heat energy, saving more electric energy and saving the drying time.
