Description

Technical Field

[0001] This utility model belongs to the field of rock wool production technology, and in particular relates to a roller cooling device for rock wool production. Background Technology

[0002] In existing rock wool production, before entering the curing furnace, the rock wool needs to be pleated using multiple rollers on a pleating machine, and then compressed to a standard thickness using pressure rollers on a press. Because the rock wool has adhesives and binders on its surface after centrifugation, these adhesives adhere to the roller surfaces during the pleating process and compression. Since the pleating and press machines are located near the curing furnace inlet at higher temperatures, the adhesives easily solidify, leading to a thick buildup on the roller surfaces. This increases the roller diameter, causing friction and eventually high hardness, making removal difficult and affecting the pleating and pressing effects. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] A typical embodiment of this utility model is as follows: Figure 1 As shown, a roller cooling device for rock wool production includes a roller, which is a roller on a pleating machine or a press, used for rock wool production. The roller includes an upper roller and a lower roller, which are arranged in parallel, and a rock wool moving channel is formed between the upper roller and the lower roller.

[0023] The upper roller conveyor includes multiple upper roller shafts 1 arranged side by side, and the lower roller conveyor includes multiple lower roller shafts 2 arranged side by side. The upper roller shafts 1 and lower roller shafts 2 have the same structure, such as... Figure 2 As shown, the upper roller shaft 1 includes a roller pressing section 101 and connecting sections 102 disposed at both ends of the roller pressing section 101. The roller pressing section 101 and the connecting sections 102 are coaxially arranged. The connecting sections 102 are fixed to the frame by bearing seats 103. The connecting sections 102 are also fitted with a drive sprocket 104 and a driven sprocket 105. The drive sprocket 104 realizes the transmission connection with the power mechanism, and the driven sprocket 105 realizes the transmission connection between the upper roller shafts 1. The roller pressing section 101 is provided with a cavity 106. A through hole 107 is opened at the axis of the connecting section 102. The through hole 107 is connected to the cavity 106.

The rotary joint 108 is also connected to a circulating water box through a water pipe. The circulating water box provides cooling water to multiple roller shafts in the upper and lower roller tracks to cool the roller shafts.

[0024] The circulating water box includes a first circulating water box 3, a second circulating water box 4, a third circulating water box 5, and a fourth circulating water box 6. The first circulating water box 3 and the second circulating water box 4 are symmetrically arranged on both sides of the upper roller conveyor. The lengths of the first circulating water box 3 and the second circulating water box 4 are the same as the length of the upper roller conveyor, and both the first circulating water box 3 and the second circulating water box 4 are arranged along the length direction of the upper roller conveyor.

[0026] The rotary joints 108 at both ends of the upper roller shaft 1 are connected to the first circulating water box 3 and the second circulating water box 4 through pipes respectively. The cooling water in the second circulating water box 4 can enter the upper roller shaft 1 through the pipe and enter the first circulating water box 3 through the other end of the upper roller shaft 1, so that the cooling water flows through the upper roller shaft 1 and cools the upper roller shaft 1. Multiple upper roller shafts 1 in the upper roller channel are connected to the first circulating water box 3 and the second circulating water box 4 to ensure that the temperature of multiple upper roller shafts 1 is constant and to prevent the adhesive on the surface of the upper roller shaft 1 from curing due to heat.

The cooling water in the third circulating water box 5 can enter the lower roller shaft 2 through the pipe and enter the fourth circulating water box 6 from the other end of the lower roller shaft 2 through the pipe, so that the cooling water flows through the lower roller shaft and cools the lower roller shaft 2. Multiple lower roller shafts 2 in the lower roller conveyor 2 are connected to the third circulating water box 5 and the fourth circulating water box 6 to ensure that the temperature of multiple lower roller shafts 2 is constant and to prevent the adhesive on the surface of the lower roller shaft 2 from curing due to heat.

[0028] Ball valves are installed on the pipes between the second circulating water box 4 and the upper roller 1, and the roller water cooling is controlled to be used independently through the ball valves.

The cooling water is circulated between the upper roller conveyor and the lower roller conveyor through the water pump 8.

[0030] A chiller 9 is installed on the pipe between the second circulating water box 4 and the water tank 7. By installing the chiller 9, the temperature of the cooling water in the pipe can be controlled, further ensuring the cooling effect.

[0031] Working principle

[0032] When it is necessary to use a pleating machine to pleat rock wool or a pressurizing machine to pressurize rock wool, open the ball valve on the pipe between the second circulating water box and the upper roller shaft, turn on the water pump, and the cooling water flows through the pipe between the upper and lower roller shafts, so that the surface temperature of the upper and lower roller shafts is kept constant, and the adhesive on the surface of the upper and lower roller shafts during the rock wool production process is prevented from being heated and solidified, which would affect the pleating and pressing effect of the rock wool.
