Description

Technical Field

[0001] The utility model belongs to the technical field of thin film evaporators, and in particular relates to a self-flushing and lubricating device for an internal bearing of a thin film evaporator. Background Art

[0002] Thin film evaporator is a commonly used chemical equipment used to concentrate and evaporate solutions or suspensions. During the operation of the thin film evaporator, the material enters the evaporator through the feed port and forms a thin film on the heating surface, which is then evaporated. However, during the evaporation process, impurities and residues in the material may adhere to key components such as bearings, affecting their normal operation and evaporation efficiency. If lubrication and flushing are not performed in time, it may cause problems such as accelerated bearing wear, increased energy consumption, excessive temperature rise, and decreased lubrication effect, thereby increasing the equipment failure rate, increasing maintenance costs, shortening equipment life, and affecting production efficiency and equipment reliability. Traditional bearing lubrication methods usually require manual operation, which is not only inefficient, but also difficult to ensure the uniformity and effectiveness of flushing and lubrication. Therefore, a new type of bearing self-flushing lubrication device is needed to solve these problems. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a self-flushing and lubricating device for the internal bearings of a thin film evaporator, which has a simple structure and is easy to operate. Through ingenious pipeline design and control system, automatic, uniform and efficient flushing and lubrication of the bearings is achieved, which can effectively improve the operating efficiency and stability of the thin film evaporator.

[0004] The utility model is realized by adopting the following technical solutions:

The top of the upper cylinder is provided with a feed port, the bottom of the lower material cone is provided with a discharge port, and the side of the lower material cone is provided with a vacuum degassing port. The discharge port is connected to the inlet of a centrifugal pump through a pipeline, and the outlet of the centrifugal pump is respectively connected to a degassing pipeline, a self-circulation pipeline and a discharge pipeline. The degassing pipeline is connected to a flushing pipeline located inside the upper cylinder through the vacuum degassing port, and the outlet of the flushing pipeline is connected to the bearing located inside the upper cylinder. The flushing and lubricating fluid is transported to the bearing through the flushing pipeline. A pressure gauge and a flow meter are provided on the degassing pipeline to monitor the pressure and flow of the fluid respectively to ensure the stable progress of the flushing and lubrication process. The upper cylinder is also connected to a vacuum pipeline, and a vacuum valve is provided on the pipeline.

[0006] It also includes a bypass line, on which a backup flow meter is provided. When a main flow meter fails, the backup flow meter can be switched to ensure stable operation of the lubrication system.

DETAILED DESCRIPTION

[0015] In order to make the purpose and technical solution of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Example 1

[0017] like Figure 1As shown, the thin film evaporator internal bearing self-flushing and lubricating device comprises a thin film evaporator 1, which comprises an upper cylinder and a lower material cone. A feed port 2 is provided at the top of the upper cylinder, a discharge port 3 is provided at the bottom of the lower material cone, and a vacuum degassing port 4 is provided on the side of the lower material cone. The discharge port 3 is connected to the inlet of a centrifugal pump 5 through a pipeline, and the outlet of the centrifugal pump 5 is respectively connected to a degassing pipeline 7, a self-circulation pipeline 8 and a discharge pipeline 9. The degassing pipeline 7 is connected to a flushing pipeline 10 located inside the upper cylinder through the vacuum degassing port 4, and the outlet of the flushing pipeline 10 is connected to a bearing 11 located inside the upper cylinder. A pressure gauge 12 and a flow meter 13 are provided on the degassing pipeline 7. The upper cylinder is also connected to a vacuum pipeline, and a vacuum valve 6 is provided on the pipeline.

[0018] The bypass pipeline 14 is also included, and a backup flow meter 15 is provided on the bypass pipeline 14.

[0019] The outlet of the flushing pipeline 10 is provided with a nozzle 16 .

[0020] The nozzle 16 is an adjustable nozzle.

[0021] A filter 17 is provided on the inlet pipeline of the centrifugal pump 5 .

[0022] It also includes a control system, which is electrically connected to the centrifugal pump 5 , the vacuum valve 6 , the pressure gauge 12 , the flow meter 13 and the standby flow meter 15 .

[0023] When using, the specific process is as follows:

[0024] First, the material to be evaporated is introduced into the thin film evaporator 1 through the feed port 2 at the top of the upper cylinder, the inlet and outlet valves of the centrifugal pump 5 are opened, so that the centrifugal pump 5 is also filled with material, and then the vacuum valve 6 is opened to evacuate the inside of the thin film evaporator 1 to a vacuum environment, and then the degassing pipeline 7 is opened. After the vacuum value is stable, the centrifugal pump 5 is started, and the centrifugal pump 5 sucks the flushing and lubricating fluid from the discharge port 3 through the pipeline, and then a part of the fluid enters the degassing pipeline 7 through the degassing pipeline 7 and the self-circulating pipeline 8, and enters the flushing pipeline 10 located inside the upper cylinder through the vacuum degassing port 4. The flushing pipeline 10 transports the fluid to the bearing 11, and evenly sprays it on the bearing 11 through the nozzle 16, so as to realize automatic flushing and lubrication of the bearing 11.

[0025] At the same time, the pressure gauge 12 and flow meter 13 on the degassing line 7 monitor the pressure and flow of the fluid respectively to ensure the stable flushing and lubrication process. When the flow meter 13 fails, it can be switched to the backup flow meter 15 on the bypass line 14 to ensure the stable operation of the lubrication system.

[0026] The fluid after flushing and lubrication falls into the discharge cone, participates in the self-circulation through the self-circulation pipeline 8, and is discharged into the next processing unit through the discharge pipeline 9 after a period of self-circulation.

[0027] The entire device is automatically controlled and monitored through a control system. The control system is electrically connected to the centrifugal pump 5, the vacuum valve 6, the pressure gauge 12, the flow meter 13 and the backup flow meter 15. The working conditions of the centrifugal pump 5 and the vacuum valve 6 are adjusted as needed, and the pressure and flow of the fluid are monitored to ensure the safe and stable operation of the device.
