Description

Technical Field

[0001] The utility model relates to the technical field of rotary drum cooling, in particular to a rotary drum spray cooling device. Background Art

[0002] The rotary drum dryer is a cylindrical body with a slightly inclined main body and adjustable speed within a certain range. The wet material is fed into the drum by the feeder. Under the rotation of the evenly distributed scrapers in the inner drum, the material is evenly distributed and dispersed in the dryer and fully contacts with the hot air (co-current or counter-current) passing through the drum, which accelerates the heat transfer and mass transfer during drying.

[0003] The existing method for cooling the outer surface of the rotary drum is to place a water pipe on the upper surface of the rotary drum and then directly spray through an aperture opened at the bottom of the water pipe. This spraying method will result in a large water flow at the initial end of the water pipe spraying, while a small water flow at the die end of the water pipe spraying, resulting in uneven cooling. In addition, the water flow at the initial end of the water pipe spraying is often relatively fast, and it is more likely to splash and disperse when it hits the outer surface of the rotary drum, resulting in uneven cooling. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing cooling method for the outer surface of the rotary drum is to place a water pipe on the upper surface of the rotary drum and then directly spray from the bottom of the water pipe. This spraying method will cause the water flow at the initial end of the water pipe spraying to be large, while the water flow at the die end of the water pipe spraying is small, resulting in uneven cooling. In addition, the water flow at the initial end of the water pipe spraying is often relatively fast, and it is more likely to splash and disperse when it hits the outer surface of the rotary drum, resulting in uneven cooling.

[0005] Therefore, based on the above-mentioned problem, the present invention proposes a rotary drum spray cooling device, which includes a mounting platform, a rotary drum is fixedly mounted on the upper portion of the mounting platform, a water trough is provided on the outer side of the mounting platform, water is poured into the water trough, and a water distribution mechanism is installed on the water trough, which distributes the water in the water trough evenly to the upper surface of the rotary drum for spray cooling.

[0006] Preferably: the water equalization mechanism includes: a water pump, a water pump is fixedly installed on one side of the water tank, one end of the water pump is connected to the water in the water tank, and the other end is connected to a delivery pipe, the delivery pipe is connected to the overflow tank, the overflow tank is connected to one side of other overflow tanks, and the overflow tank is located on the upper part of the rotary drum.

[0007] Preferably: the overflow trough is box-shaped, and multiple spouts are provided on the left and right sides of the overflow trough, with larger openings along the inside of the overflow trough and smaller openings along the outside of the overflow trough. The lower outer side of the spout is connected to multiple water distribution troughs, which are opened on the side of the overflow trough and have a stump structure.

[0008] Beneficial effect: Start the water pump, which will drive the water in the water tank to be pumped upwards, and the water will be transported to the delivery pipe, and then transported to the overflow trough by the delivery tank. The overflow trough and other overflow troughs are interconnected, thus forming a communicating vessel principle, and the water is evenly placed on the overflow trough. Since the spout is connected to multiple water balancing troughs, and the water balancing trough is set as a stump structure, the bag water will flow back evenly into the rotary drum, and the water will be evenly sprinkled in the rotary drum for cooling.

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0013] Reference Figures 1 to 2 The rotary drum spray cooling device includes a mounting platform 1, on the upper part of which a rotary drum 2 is fixedly mounted. The device is characterized in that a water trough 3 is provided on the outer side of the mounting platform 1, water is poured into the water trough 3, and a water distribution mechanism is installed on the water trough 3. The water distribution mechanism evenly distributes the water on the water trough 3 to the upper surface of the rotary drum 2 for spray cooling.

[0014] Preferably: the water equalization mechanism includes: a water pump 4, a water pump 4 is fixedly installed on one side of the water tank 3, one end of the water pump 4 is connected to the water in the water tank 3, and the other end is connected to the delivery pipe 5, the delivery pipe 5 is connected to the overflow tank 6, the overflow tank 6 is connected to one side of other overflow tanks 6, the overflow tank 6 is located on the upper part of the rotary drum 2, when in use, start the water pump 4, the start of the water pump 4 will drive the water in the water tank 3 to be pumped upwards, the water is transported to the delivery pipe 5, and then transported to the overflow tank 6 by the delivery tank, and the overflow tank 6 and other overflow tanks 6 are connected to each other, thus forming a communicating vessel principle.

[0015] Preferably: the overflow trough 6 is box-shaped, and the left and right sides of the overflow trough 6 are provided with multiple spouts 7 with larger openings along the inside of the overflow trough 6 and smaller openings along the outside of the overflow trough 6. The lower outer side of the spout 7 is connected with multiple water distribution troughs 8, and the water distribution troughs 8 are opened on the side of the overflow trough 6. The water distribution troughs 8 are in a stump structure, which evenly places water on the overflow trough 6. Since there are multiple spouts 7 on the side of the overflow trough 6, the water in the overflow trough 6 will first spread out from the spout 7. Because there are multiple water distribution troughs 8 connected in the spout 7, and the water distribution troughs 8 are set as a stump structure, the bag water will evenly flow back into the rotary drum 2, and the water will be evenly sprinkled in the rotary drum 2 for cooling.

[0016] Working principle:

[0017] When in use, start the water pump 4. The start of the water pump 4 will drive the water in the water tank 3 to be pumped upwards, and the water will be transported to the delivery pipe 5, and then transported to the overflow tank 6 by the delivery tank. The overflow tank 6 and other overflow tanks 6 are interconnected, thus forming a communicating vessel principle, and the water is evenly placed on the overflow tank 6. Since there are multiple spouts 7 on the side of the overflow tank 6, the water in the overflow tank 6 will first spread out from the spout 7. Because there are multiple water balancing tanks 8 connected to the spout 7, and the water balancing tank 8 is set as a stump structure, the bag water will be evenly backflowed into the rotary drum 2, and the water will be evenly sprinkled in the rotary drum 2 for cooling.
