Description

Vacuum rake dryer clamping sleeve

Technical Field

The utility model relates to a vacuum rake dryer presss from both sides cover belongs to desiccator technical field.

Background

1) The existing vacuum rake dryer jacket is easy to produce accidents because the inner cylinder is vacuum and negative pressure, the jacket is internally filled with heating medium and normally is steam and positive pressure, the inner cylinder wall is easy to deform and even shrink due to outward pushing and inward sucking, and the jacket is easy to produce accidents.

2) In order to prevent deformation, the inner cylinder in the prior art conventionally adopts a thick steel plate to increase the strength, but the heat conduction effect is greatly influenced due to the thick steel plate.

3) The inner cylinder is made into a cylindrical shape, the higher the roundness is, the better the roundness is, the lower the roundness is in the prior art, the clearance between the heat conduction rake matched with the inner cylinder and the inner cylinder wall is large, and thicker material scale is easy to adhere to the inner cylinder wall during operation, thereby greatly reducing heat conduction and influencing heat efficiency.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned defect, the utility model aims to provide a rational in infrastructure, improve a vacuum rake dryer clamp cover of inner tube intensity and performance.

Therefore, the utility model adopts the technical scheme that: a reinforcing rib plate is arranged in the jacket, the inner end of the reinforcing rib plate is arranged on an inner cylinder of the dryer, and a cavity for flowing of a heating medium is formed in the reinforcing rib plate.

Furthermore, the cavity is formed at the joint of the reinforcing rib plate and the inner cylinder, and a part of the cavity is formed on one part of the outer surface of the inner cylinder.

Furthermore, in the axial direction of the jacket, the adjacent reinforcing rib plates are connected through connecting rods.

Furthermore, the reinforcing rib plate forms an arc structural shape form.

Furthermore, the reinforcing rib plates are discontinuously arranged in the circumferential direction of the jacket, and are uniformly distributed on the outer surface of the jacket.

Furthermore, a heat conducting rod tightly attached to the inner wall of the inner barrel is arranged in the inner barrel, a heat conducting rake is arranged on the inner barrel, and the heat conducting rod and the heat conducting rake are arranged in a staggered mode and do not interfere with each other.

The utility model has the advantages that: the structure of the utility model can increase the strength of the inner cylinder, and the wall of the inner cylinder can keep not deforming for a long time; the inner cylinder wall is high in roundness during manufacturing, the gap between the heat conduction rake and the inner cylinder wall is small, the scale is not easy to adhere, the heat efficiency is good, the scale drying object is not easy to generate, the drying quality is good, and the practicability is good.

Detailed Description

A vacuum rake dryer jacket is characterized in that a reinforcing rib plate 2 is arranged in a jacket 1, the inner end of the reinforcing rib plate 2 is arranged on an inner cylinder 3 of a dryer, and a cavity 21 for flowing a heat supply medium is formed in the reinforcing rib plate 2.

Furthermore, the cavity 21 is formed at the joint of the reinforcing rib plate 2 and the inner cylinder 3, and a part of the cavity 21 is formed on one part of the outer surface of the inner cylinder 3.

Furthermore, in the axial direction of the jacket 1, the adjacent reinforcing rib plates 2 are connected through connecting rods 4.

Further, the reinforcing rib plate 2 forms a circular arc structural shape.

Furthermore, the reinforcing rib plates 2 are discontinuously arranged in the circumferential direction of the jacket 1, and the reinforcing rib plates 2 are uniformly distributed on the outer surface of the jacket 1.

Further, a heat conducting rod 5 tightly attached to the inner wall of the inner cylinder 3 is arranged in the inner cylinder 3, a heat conducting rake 6 is arranged on the inner cylinder 3, and the heat conducting rod 5 and the heat conducting rake 6 are arranged in a staggered mode without interference.

The following is a further explanation of the present invention to better understand the present invention: the utility model discloses set up bars formula deep floor 2 in pressing from both sides cover 1, arrange into cylindricly, the 3 wall outsides of vacuum rake dryer inner tube are fixed on bars formula deep floor 2 inner edges, and vacuum rake dryer outer wall is fixed in bars formula deep floor 2 outer fringe. The utility model discloses having add deep floor 2, having strengthened intensity greatly, the utility model discloses 3 walls of inner tube do not warp, and 3 walls of inner tube also do not have the bodiness, and on the contrary still possible attenuation improves heat-conduction, increases thermal efficiency. Furthermore, the reinforcing rib plate 2 of the utility model is provided with a plurality of holes for the flow of heating medium (conventionally steam), and the number of the holes is determined according to the size of the vacuum rake dryer, the reinforcing rib plate 2 and the characteristics of the heating medium; the utility model further adopts the reinforcing rib plate 2 made of metal material, which increases the firmness and also enhances the heat transfer between the reinforcing rib plate and the inner cylinder 3; the utility model discloses a preferential stainless steel that chooses for use of deep floor 2.

The utility model discloses further 2 upper ends of deep floor fix the top cap on the vacuum rake dryer, and 2 lower extremes of deep floor fix chassis under the vacuum rake dryer, easily make cylindricly, easily improve the precision of 3 wall circularity preparations of inner tube, and greatly reduced heat conduction harrow 6 and the clearance of 3 walls of inner tube.

The utility model discloses 2 quantity of deep floor, according to vacuum and heat medium pressure to and 3 wall stainless steel plate thickness of inner tube and decide, do not make specific restrictions here.
