Description

Technical Field

[0001] The utility model relates to the technical field of cloth processing equipment, and more specifically to an improved drying drum drying machine. Background Art

[0002] The cylinder dryer is a dryer that transfers heat by contact with the cylinder surface. It is mainly used for drying cotton and polyester-cotton blended fabrics. It can also be used for drying warp yarn after continuous pad dyeing and washing. The most commonly used cylinder dryer is vertical, while horizontal and bridge types are relatively rare.

[0003] As shown in the existing drum dryer (such as application number: CN202220266487.8, a drum dryer), the "circumferential wall of the drum is evenly penetrated with a number of heat transfer holes for connecting the interior of the drum and the surface of the fabric" to discharge heat to the surface of the fabric through the heat transfer holes. However, since the drum is cylindrical and the fabric surface is not annularly wrapped, at this time, the heat on the drum surface that is not in contact with the fabric will be discharged through the heat transfer holes, resulting in a large waste of heat.

The cover cavity of the collecting cover is expanded in the direction of the through pipe toward the cylinder, and the surrounding edge surface covered toward the cylinder is the same as the surrounding edge surface of the cloth layer that fits the cylinder.

[0009] As a preferred technical solution of the utility model, the hollow ring plate is composed of a ring plate and one plate end thereof evenly provided with multiple groups of third through holes respectively connected to the other plate end thereof, and the hole ends of the third through holes face the cylinder.

[0010] As a preferred technical solution of the utility model, the shaft end of the cylinder is provided with a close-rotating component which rotates in sealing engagement with the through pipe and is fixed to the frame.

[0011] As an optimal technical solution of the utility model, the close rotating component includes a rotating ring which is arranged outside the through pipe and fixed to the cylinder body, a ring groove which surrounds the through pipe is provided inside the rotating ring, a sealing ring is fitted in the ring groove, a pressure ring groove which fits and presses the sealing ring is provided outside the through pipe, the outside of the rotating ring is rotatably connected to a bearing seat provided with a bearing, and the bearing seat is fixedly mounted on the outside of the frame.

[0022] Embodiment 1:

[0023] like Figures 1 to 3 As shown, this embodiment proposes: an improved drum drying machine, comprising a frame 1;

[0024] A plurality of cylinders 2 (such as Figure 1 As shown, multiple groups of cylinders 2) are arranged in sequence from top to bottom;

[0025] Each group of cylinders 2 is provided with a through pipe 3 (such as Figure 2 As shown, a through pipe 3 is inserted in the center of the left end of the cylinder 2, and a component for passing heat flow into the through pipe 3 outside the cylinder 2 is provided outside the through pipe 3, and the component for passing heat flow can be a pipe for discharging hot steam at the "vent" in the background technology, etc., which is the prior art);

[0026] The outer periphery of the cylinder 2 is evenly provided with a plurality of first through holes 5 (such as Figure 2 , 3 As shown: a cylinder cavity is provided in the cylinder 2, and a first through hole 5 communicating with the inside of the cylinder 2 is provided on the outer side of the annular periphery of the cylinder 2, and multiple groups are reasonably arranged to improve ventilation uniformity;

[0027] The outer periphery of the multiple groups of cylinders 2 is provided with a non-loop-closed bonding transmission cloth layer 6 (the bonding surface can be as follows Figure 3 shown);

[0028] The cylinder 2 is provided with a heat conducting component 7 for directing the heat flow of the through tube 3 placed in the cylinder 2 to flow toward the end where the cylinder 2 and the cloth layer 6 are fitted (i.e., the heat flow of the through tube 3 placed in the cylinder 2 is directed toward the position where the cylinder 2 and the cloth layer 6 are fitted, thereby concentrating the heat flow to the fitting end and improving the utilization rate of the heat flow).

[0029] In order to implement the above-mentioned heat-conducting component 7, it is proposed that Figure 2 , 3 As shown, the specific structure and composition of the heat conducting component 7 can be as follows: the heat conducting component 7 includes a collecting cover 71 (such as Figure 2 , 3 As shown, a cover end is fixed with a through pipe 3 and is located inside the cylinder cavity);

[0030] The collecting cover 71 is provided with a cover cavity (i.e., the inner side space of the collecting cover 71 is the cover cavity, such as Figure 3 The cover cavity shown is the inner wall position where the hollow ring plate 72 is provided in the collecting cover 71. Figure 2 The cover cavity shown is the front inner wall position of the collection cover 71);

[0031] The heat flow from the tube 3 out of the cylinder 2 flows into the cover cavity (such as Figure 2 As shown, the heat flow is concentrated in the hood cavity when it flows forward.

[0032] At least one set of hollow ring plates 72 is fixedly installed inside the collecting cover 71 for the heat flow to flow evenly toward the cylinder 2 (the heat flow entering the cover cavity is evenly distributed through the hollow ring plates 72 to improve the balance).

[0033] The outer side of the through-tube 3 is evenly provided with a plurality of groups of second through holes for heat flow to communicate with the inner side of the collecting cover 71 respectively, and the plurality of groups of second through holes are all located inside the collecting cover 71 (according to the above, the heat flow enters the cover cavity through the plurality of groups of second through holes to communicate the inside of the through-tube 3 with the inside of the collecting cover 71, and the plurality of groups of second through holes are evenly arranged to provide uniformity for the initial entry into the inner side of the collecting cover 71);

[0040] The swivel ring 41 is rotatably connected to a bearing seat 44 provided with a bearing (such as Figure 2 As shown, the swivel 41 rotates outside the bearing inside the bearing seat 44. According to the above, the swivel 41 can rotate in a sealed manner on the outside of the through pipe 3 by the sealing ring 43 (as shown in FIG. Figure 2 As shown, a swivel 41 with a closed loop opening is fixed in the center of the right end of the cylinder 2, and a bearing seat 44 provided with a bearing in the same communication mode as the swivel 41 is rotatably connected);

[0041] The bearing seat 44 is fixedly mounted on the outside of the frame 1 to fix the position of the cylinder 2 support.

[0042] The ring grooves 42 are provided in multiple groups and are evenly distributed on the inner side of the rotating ring 41.
