Detailed Description

The technical solutions in the embodiments of the present utility model are clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may be practiced in other ways other than those described herein, and persons skilled in the art will readily appreciate that the present utility model is not limited to the specific embodiments disclosed below.

As shown in fig. 1 to 4, a gypsum cooling device comprises a horizontal rotatable cylinder 1 and a plurality of heat exchange tubes 4, wherein the front end of the cylinder 1 is provided with a fixed air collecting box 11, the fixed air collecting box is connected with the cylinder 1 through a bearing 13, the top of the air collecting box 11 is provided with an air outlet 14, the air outlet 14 is connected with a fan, the heat exchange tubes 4 are parallel to the axis of the cylinder 1, the heat exchange tubes 4 penetrate through the head end and the tail end of the cylinder 1, the head end of the cylinder 1 is discharged, the tail end of the cylinder is provided with a fixed feeding pipe 15, and the feeding pipe 15 is connected with the tail end surface of the cylinder 1 through the bearing 13.

The device also comprises

The filter screen 3 is arranged at the tail end of the cylinder body 1, the filter screen 3 covers the tail end opening of the heat exchange tube 4, specifically, the end face of the tail end of the cylinder body 1 is provided with an inner annular plate 31 and an outer annular plate 32 which are coaxial, the filter screen 3 is annular, the filter screen 3 is erected by two annular plates, and a space is reserved between the filter screen 3 and the tail end opening of the heat exchange tube 4, so that the filter screen 3 and the cylinder body 1 synchronously rotate;

the annular fixing plate 12 is sleeved on the outer side of the tail end of the cylinder body 1, the annular fixing plate 12 is connected with the cylinder body 1 through a bearing 13, and the annular fixing plate 12 is fixedly arranged on the ground through a supporting rod (not shown);

the brush rod 2 is arranged on the inner side wall of the annular fixing plate 12, a brush on the brush rod 2 is positioned on one side of the filter screen 3 away from the heat exchange tube 4 and is adjacent to the filter screen 3, and the brush rod 2 spans across the two annular plates.

The theory of operation of this application is, provides the negative pressure in the collection bellows 11 through exhaust pipe 14 for outside air gets into from heat exchange tube 4 tail end after filtering through filter screen 3, and with gypsum heat transfer after barrel 1 is inside, reentrant collection bellows 11 is followed by the discharge, and rotatory filter screen 3 then is cleaned by rather than adjacent and fixed brush-holder stud 2, keeps heat exchange tube 4 air inlet smooth and easy.

Further, in order to prevent the peeled dust on the filter screen 3 from being adsorbed again, as shown in fig. 1 and 3, a dust collecting cover 51 may be disposed inside the annular fixing plate 12, the dust collecting cover 51 is adjacent to the brush bar 2, the dust collecting cover 51 is communicated with the dust collecting pipe 5, and the dust collecting pipe 5 provides negative pressure for the dust collecting cover 51, for example, an external negative pressure fan.

And the dust collection cover 51 is located at the upstream side of the brush bar 2 in the rotation direction of the filter screen 3, for example, in fig. 3, the filter screen 3 rotates in the counterclockwise direction, and then the dust collection cover 51 is located under the brush bar 2, and the dust collection cover 51 can collect dust or particles brushed down by the brush bar 2.

Alternatively, the dust hood 51 covers the brush bar 2, i.e. as shown in fig. 5, the dust hood 51 covers the brush bar 2 more comprehensively, but the disadvantage is that the replacement of the brush bar 2 is somewhat cumbersome compared to the first one.

Further, the negative pressure of the dust collection cover 51 can be provided by the air collection box 11, for example, the dust collection cover 51 is communicated with the air collection box 11 through the dust collection pipe 5, so that the device only needs to use one fan.

Because the dust collection cover 51 is communicated with the air collection box 11, in order to prevent the suction force from being provided on both sides of the corresponding part of the filter screen 3 when the opening end of the heat exchange tube 4 passes through the dust collection cover 51, and in order to prevent a small amount of dust peeled off from the inside of the filter screen 3 from being sucked by the heat exchange tube 4 when the part of the filter screen 3 is treated by the brush bar 2, the suction of the heat exchange tube 4 can be blocked temporarily at the moment;
