Description

Technical Field

[0001] This utility model relates to the technical field of internal mixer equipment, and in particular to a rapid cooling structure for the mixing tank of an internal mixer. Background Technology

[0002] Internal mixers are used for mixing rubber, plastics, and various rubber compounds and plastics. They melt PVC mixtures in a very short time and promote gelation. Colorants and foaming agents are added and mixed here. An internal mixer includes a mixing chamber and a mixing shaft, which is located inside the mixing chamber. During operation, the mixing chamber generates high temperatures. Currently, cooling is generally achieved by water cooling. A heat exchange chamber is set on the outer wall of the mixing chamber. Water passes through the cooling chamber to cool the mixing chamber. The heat exchange chamber on the outer wall of the mixing chamber usually has a single inlet and outlet. During cooling operations, the water in the heat exchange chamber cannot be discharged quickly, resulting in slow cooling. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 3 As shown, this embodiment provides a rapid cooling structure for a mixing tank of a mixer, including a mixing tank 1. A U-shaped sleeve 2 is installed on the outer wall of the mixing tank 1. A heat exchange space is provided between the U-shaped sleeve 2 and the outer wall of the mixing tank 1. The U-shaped sleeve 2 has an inlet and an outlet at both ends. A partition 3 extending around the axis of the mixing tank 1 is provided on the outer wall of the mixing tank 1. The partition 3 is connected to the outer wall of the mixing tank 1 by welding. The partition 3 divides the heat exchange space into multiple heat exchange channels. The height of the partition 3 is equal to the depth of the heat exchange space, dividing the heat exchange space into three heat exchange channels. A first box 4 and a second box 5 are provided at both ends of the U-shaped sleeve 2. The first box 4 has three liquid inlet chambers that are respectively connected to the inlets of the three heat exchange channels. The second box 5 has three liquid outlet chambers that are respectively connected to the outlets of the three heat exchange channels. The first box 4 has multiple first channels 401 that are respectively connected to the multiple heat exchange channels. The second box 5 has multiple second channels 501 that are respectively connected to the multiple heat exchange channels.

[0016] In this embodiment, each liquid inlet chamber of the first housing 4 is provided with a filter screen 6. The filter screen 6 is detachably installed in the first housing 4. Preferably, the filter screen 6 is installed in the first housing 4 by screws. The filter screen 6 can filter impurities in the cooling water and prevent impurities from clogging the heat exchange channel.

[0017] In this embodiment, both the first box 4 and the second box 5 are provided with a sealing cover 7 that can be opened. By opening the sealing cover 7, the debris inside the first box 4 and the second box 5 can be cleaned.

[0018] In this embodiment, the bottom of the U-shaped sleeve 2 is provided with an openable drain port 8, which is used to drain the cooling water in the heat exchange space during maintenance and cleaning.

[0019] In this embodiment, a round rod 9 is connected to the bottom of the mixing tank 1, and the lower end of the round rod 9 passes through the U-shaped sleeve 2. A through hole communicating with the inside of the mixing tank 1 is opened on the round rod 9, and the through hole is used to install a temperature sensing rod for monitoring the temperature inside the mixing tank 1.

[0020] In this embodiment, the rapid cooling structure for the mixing tank of the internal mixer introduces cooling water into the heat exchange space through the inlet during operation. Since the heat exchange space is divided into multiple heat exchange channels, multiple independent water flows can pass through the heat exchange space. Each independent water flow can be matched with multiple independent water pumps. The multiple independent water pumps inject cooling water into the heat exchange space through multiple first channels 401. After absorbing heat, the cooling water enters the second box 5 through multiple second channels 501 and is discharged. The liquid inlet chamber is connected to an external water tank through an inlet pipe, and the liquid outlet chamber is connected to an external water tank through an outlet pipe. The independent water pumps are installed on the inlet pipe. This embodiment of the rapid cooling structure for the mixing tank of the internal mixer has multiple heat exchange channels, and each heat exchange channel performs heat exchange operations through an independent water flow. After absorbing heat, the cooling water can be quickly discharged from the heat exchange space, improving cooling efficiency.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
