Description

Air-inducing pretreatment device for roller drying kiln

Technical Field

The utility model relates to a lithium carbonate drying equipment technical field, concretely relates to cylinder drying kiln induced air preprocessing device.

Background

A disc dryer is often used as a lithium carbonate drying device. However, the disc dryer has the defects that a large number of fasteners are easy to fall off, rake teeth are easy to generate magnetic substances due to abrasion, and the like.

As shown in fig. 1, the drum drying kiln has many advantages such as large handling capacity, high heat transfer efficiency, and small steam consumption. Lithium carbonate 1 enters from a spiral inlet 2 and is conveyed into the roller drying kiln through a double spiral 3. The dried tail gas is discharged from a tail gas outlet 5 through an induced draft tube 4. When the pretreatment device is not added, lithium carbonate 1 falling from the steam array pipe is sucked into the air inducing pipe, and is slowly accumulated at dead angles or elbows of the air inducing pipe to cause the air inducing pipe to be blocked and tail gas to be discharged smoothly, so that materials cannot be dried, and the quality of lithium carbonate products and the smoothness of production flow are seriously influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to prior art's defect and not enough, provide a simple structure, reasonable in design, convenient to use's cylinder drying kiln induced air preprocessing device, at cylinder drying kiln induced air pipe entrance point welding preprocessing device, block the lithium carbonate powder that falls along with the cylinder drying kiln rotation for it can not inhale in the tail gas induced air pipe.

In order to achieve the above object, the utility model adopts the following technical scheme: it is welded at the inlet end of the induced draft tube of the roller drying kiln; it comprises an arc plate, a guide plate and a support plate; the arc angle of the arc plate is 110-130 degrees and covers the upper part of the inlet end of the induced draft pipe of the roller drying kiln; the guide plates are symmetrically arranged on two sides of the arc plate; the support plate is fixed at the lower part of the guide plate and is welded and fixed with the induced draft tube of the roller drying kiln;

further, the width L1 of the circular arc plate is 400 mm;

further, the arc angle alpha of the arc plate is 120 degrees;

further, the length L2 of the baffle is 300 mm.

After the structure is adopted, the utility model discloses beneficial effect does: a cylinder drying kiln induced air preprocessing device, can greatly reduce the lithium carbonate and be inhaled the probability in the induced air pipe to make tail gas effectively discharge, guaranteed the dry effect of lithium carbonate, and have simple structure, set up reasonable, cost of manufacture low grade advantage.

Description of reference numerals:

1. lithium carbonate; 2. a spiral inlet; 3. double helix; 4. an induced draft pipe; 5. a tail gas outlet; 6. a circular arc plate; 7. a baffle; 8. and a support plate.

Detailed Description

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

Referring to fig. 1 to 3, the technical solution adopted by the present embodiment is: it is welded at the inlet end of the induced draft tube 4 of the roller drying kiln; it comprises an arc plate 6, a guide plate 7 and a support plate 8; the width L1 of the arc plate 6 is 400 mm; the arc angle of the arc plate 6 is 120 degrees, and the arc plate covers the upper part of the inlet end of the induced draft tube 4 of the roller drying kiln; the distance between the arc plate 6 and the top of the roller is 300 mm; the guide plates 7 are symmetrically arranged at two sides of the arc plate 6, and the length L2 of the guide plates 7 is 300 mm; the support plate 8 is fixed at the lower part of the guide plate 7 and is welded and fixed with the induced draft tube 4 of the roller drying kiln;

lithium carbonate 1 enters from a spiral inlet 2 and is conveyed into the roller drying kiln through a double spiral 3. The dried tail gas is discharged from a tail gas outlet 5 through an induced draft pipe 4; after the mouth of pipe of induced duct 4 adds preprocessing device, the lithium carbonate 1 that drops is sheltered from and drops along guide plate 7 by preprocessing device circular arc board 6, avoids the lithium carbonate to pile up in a large number and greatly reduced lithium carbonate gets into the probability of induced duct 4 in preprocessing device top. The utility model discloses can greatly reduce lithium carbonate 1 and be inhaled the probability in induced duct 5 to make tail gas effectively discharge, and then guaranteed lithium carbonate 1's drying effect.

The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
