Abstract

The utility model provides a turning-plate type drying drum, which is composed of a hot air supply device, a discharge duct, a hopper, a drum, and an air drafting mechanism, wherein, the drum which is supported by a supporting device is driven by a motor and a driving device to rotate; one end of the drum is connected with the hot air supply device, and the other end is connected with a draft fan; a turning plate is arranged in the drum. The utility model is characterized in that a check ring is arranged in the drum in a radial direction, so the number of times of turning and hoisting of materials is increased under the action of the check ring; the time for baking the materials in the drum is prolonged, water contents of the materials can be dried, and the granular strength of the materials can be enhanced; therefore, the utility model can realize the different baking of materials which meet standards without enhancing baking temperatures and increasing the length of the drum.

Description

A kind of turnover plate type drying roller

The utility model relates to a kind of turnover plate type drying roller, especially a kind ofly can prolong stoving time, guarantees the drying roller of product quality.

The application of drying roller in chemical industry and other industry is comparatively extensive.Its process characteristic is, material is put into secondary balling-up district from the chute of cylinder head, be accompanied by the rotation of cylinder, material is also rotated and rolling downwards thereupon, the particle surface of balling-up is slided in the garden more, made the powder balling-up once more of carrying secretly simultaneously, after material enters the turnover panel district, under the turnover panel effect, material is rolled and kick up, reach and move dry again purpose.But because different materials has different water content requirements, water content as the low concentration complex fertilizer is 5%, and the water content of high concentration compound fertilizer only is 2.5%, in order to reduce water content, guarantee the product quality of complex fertilizer, prior art is solved by raising baking temperature or lengthening drum length, but the former easily causes material to superfuse also slagging scorification and influences ordinary production, especially the heating-up temperature of compound fertilizer of high concentration only allows below 130 ℃, therefore be difficult to remove moisture content with this method, the latter then will increase investment, and occupied ground is unfavorable for reducing production costs.

The purpose of this utility model is to provide a kind of temperature that promptly do not need to improve, and does not need to increase drum length again and just can guarantee baking quality turnover plate type drying roller.

The technical solution of the utility model is: it is by hot air supply device, blanking chute and hopper, cylinder and air exhauster constitute, and its intermediate roll supports by bracing or strutting arrangement, and by motor and its rotation of actuator drives, cylinder one end links to each other with hot air supply device, the other end links to each other with air exhauster, and being used for provides hot blast in cylinder, is provided with turnover panel in the cylinder, it is characterized in that in cylinder, being provided with back-up ring, so that prolong the holdup time of material in cylinder, reduce water content, improve baking quality.Described back-up ring is one circular, radially is located on the inner wall of rotary drum and is arranged on the turnover panel end, and this back-up ring is established one and to be placed on the cylinder postmedian be good at least in cylinder, so that prolong the holdup time of material in cylinder, improve the material baking quality.Being connected to welding or being spirally connected or riveting of back-up ring and inner wall of rotary drum, and can increase or reduce back-up ring quantity according to the different material requirement.

The utility model compared with prior art, have following advantage and effect: owing in cylinder, be provided with back-up ring, make material under the back-up ring effect, increase the number of times that rolls and kick up, the stoving time of prolongation in cylinder, not only can dry the moisture content in the material, but also improve material particles intensity, therefore, not improving baking temperature, increasing under the situation of drum length, can realize the baking of various materials up to standard.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the A place amplification assumption diagram of Fig. 1;

Fig. 3 is the N-N sectional drawing.

Below in conjunction with accompanying drawing the utility model is described further, is not limited only to this but hold within the utility model.

Among the figure, 1 is hot-blast stove, and 2 is warm-air pipe, one end links to each other with hot-blast stove, and the other end is connected with cylinder, and 3 are the blanking chute, 4 is feed hopper, is located at the cylinder top, and 5 is support, 6 is cylinder, 7 is support roller, is supported by

bracing frame

8, and 9 is motor, 10 is transmission device, be used for head roll and rotate, 11 is turnover panel, axially is located on cylinder 6 inwalls, 12 is back-up ring, radially be located at the rearward end of turnover panel 11 in the cylinder by screw 15 and angle steel 16, and can optionally back-up ring be set as required, and use bolted in a plurality of or single turnover panel rear end, 13 is discharging opening, and 14 is suction opeing.

Claims

1, a kind of turnover plate type drying roller, it is by hot air supply device, blanking chute and hopper, cylinder and air exhauster constitute, and its intermediate roll supports by bracing or strutting arrangement, and by motor and its rotation of actuator drives, cylinder one end links to each other with the heat supply device, the other end links to each other with air exhauster, is provided with turnover panel in the cylinder, it is characterized in that radially being provided with in the cylinder back-up ring.

2, cylinder according to claim 1 is characterized in that described back-up ring is one circular, is located on the inner wall of rotary drum and is arranged on the turnover panel end, and this back-up ring is established one and to be placed on the cylinder postmedian be good at least in cylinder.
