Description

Technical Field

[0001] This utility model relates to the field of dispersing machine technology, and specifically to a new type of dispersing machine. Background Technology

[0002] Traditional dispersing machines have the following problems:

[0003] 1. Traditional breakers use a motor to drive a small pulley, which in turn drives a large pulley via a belt. The large pulley then drives the drive shaft to rotate, and the breaker is mounted on the drive shaft and rotates with it. This power transmission structure causes the drive shaft to bear not only the rotational load but also the radial traction force generated by the belt drive, making the drive shaft prone to instability and resulting in a shorter service life.

[0004] 2. The traditional dispersing machine has an unreasonable sealing structure design, which makes it easy for dust to enter the bearing, leading to easy damage to the bearing.

[0005] 3. Due to the high temperature in the machine's working area within the material trough, the traditional dispersant's cooling system is poorly designed, resulting in excessively high operating temperature of the drive shaft support bearing, which is prone to damage. Utility Model Content

[0006] In view of this, the present invention aims to provide a new type of dispersing machine that can improve the service life of the drive shaft and can operate stably for a long time in high-temperature environments.

[0007] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0008] This utility model provides a novel dispersing machine, including a permanent magnet motor, a drive shaft, a dispersant, a base plate, a gas purging sealing and cooling device, and a drive shaft support bearing. The drive shaft has a hollow structure and is equipped with a cooling water inlet and a cooling water outlet to allow cooling water to be introduced into the drive shaft for cooling. The drive shaft support bearing is installed inside the gas purging sealing and cooling device. The drive shaft is coaxially connected to the permanent magnet motor, the drive shaft support bearing, and the dispersant in sequence. The gas purging sealing and cooling device is connected to the base plate, and the base plate is connected to an external tank.

[0009] Furthermore, the gas purging sealing and cooling device includes an air inlet, a water inlet, and a water outlet. The gas purging sealing and cooling device is connected to an external air source through the air inlet and to an external cooling water supply device through the water inlet.

[0010] Furthermore, it also includes a cooling water jacket, which is connected to the base plate and installed at one end of the gas purging sealing and cooling device.

[0011] Furthermore, it also includes a mounting base, the gas purging sealing and cooling device and the permanent magnet motor are respectively connected to the mounting base, and the mounting base is connected to the base plate.

[0012] Furthermore, the mounting base is connected to the base plate by bolts.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) This utility model adopts a permanent magnet motor direct drive transmission shaft. The central shaft of the permanent magnet motor and the transmission shaft are located on the same center line, eliminating the radial traction force formed during the transmission process and greatly extending the service life of the transmission shaft.

[0015] (2) The present invention is equipped with a gas purge seal to effectively separate dust from the transmission shaft support bearing, thereby creating a clean working environment for the transmission shaft support bearing.

Detailed Implementation

[0020] To provide a more detailed understanding of the features and technical content of this utility model, the implementation of this utility model will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit this utility model.

[0021] like Figure 1 As shown, a novel dispersing machine includes a permanent magnet motor 2, a drive shaft 6, a dispersing device 7, a base plate 4, a gas purging sealing and cooling device 3, a cooling water jacket 5, a drive shaft support bearing, and a mounting base 8.

[0022] The drive shaft 6 is a hollow structure, and is provided with a cooling water inlet 61 and a cooling water outlet 62. The cooling water inlet 61 is connected to an external cooling water supply device to introduce cooling water into the drive shaft 6 to cool the drive shaft 6, and the cooling water is discharged from the cooling water outlet 62.

[0023] The drive shaft support bearing is installed inside the gas purging sealing and cooling device 3 to achieve a mechanical seal for the drive shaft 6. The drive shaft 6 is coaxially connected to the permanent magnet motor 2, the drive shaft support bearing, and the scatterer 7 in sequence. The gas purging sealing and cooling device 3 and the permanent magnet motor 2 are respectively connected to the mounting base 8. The mounting base 8 is bolted to the base plate 4. The gas purging sealing and cooling device 3 and the permanent magnet motor 2 are fixedly connected to the base plate 4 through the mounting base 8. The mounting base 8 makes the installation and disassembly of the gas purging sealing and cooling device 3 and the permanent magnet motor 2 more convenient.

[0024] The base plate 4 is connected to the external tank 1. The dispersing machine is fixed to the tank 1 through the base plate 4. One end of the dispersing device 7 is located in the material tank, and the other end containing the permanent magnet motor 2 is located outside the material tank.

[0025] The cooling water jacket 5 is connected to the base plate 4. The cooling water jacket is located at one end of the gas purging seal and cooling device 3 located in the material tank, and cools the end of the gas purging seal and cooling device 3 located in the material tank.

[0026] The gas purging sealing and cooling device 3 includes an air inlet, a water inlet, and a water outlet. The gas purging sealing and cooling device 3 is connected to an external air source through the air inlet, performing gas purging to effectively separate dust from the drive shaft support bearing, creating a clean working environment for the drive shaft support bearing and improving its service life. The gas purging sealing and cooling device 3 is connected to an external cooling water supply device through the water inlet, providing cooling water to the internal drive shaft support bearing. The cooling water is discharged through the water outlet, maintaining the operating temperature of the entire transmission sealing system within the allowable temperature range, ensuring the purging machine can operate stably for a long time in high-temperature environments.

[0027] The working process of the novel material breaker in this embodiment is as follows: The material breaker is installed on the tank through the base plate 4. The permanent magnet motor 2 drives the transmission shaft 6, which drives the breaker 7 to rotate, thereby breaking up the blocky material in the material tank. During the operation, cooling water is introduced into the transmission shaft 6 through the cooling water inlet 61 to reduce the temperature of the transmission shaft 6. Gas and cooling water are introduced into the gas blowing sealing and cooling device to blow away the dust at the transmission shaft support bearing and cool the transmission shaft support bearing.

[0028] This utility model adopts a permanent magnet motor 2 to directly drive the transmission shaft 6. The central shaft of the permanent magnet motor 2 and the transmission shaft 6 are located on the same center line, eliminating the radial traction force formed during the transmission process and greatly extending the service life of the transmission shaft. A gas purging sealing and cooling device 3 is set up to effectively separate dust from the transmission shaft support bearing, creating a clean working environment for the transmission shaft support bearing and ensuring that the working temperature of the transmission shaft support bearing is maintained within the allowable temperature range, ensuring that the shredder can operate stably for a long time in a high-temperature environment.
