Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste oil treatment equipment, in particular to a filter element self-cleaning type industrial waste oil regeneration equipment. Background Art

[0002] Industrial waste oil regeneration refers to the treatment of used industrial oils through a series of physical or chemical methods to remove impurities and deteriorated components, restore their original performance, or convert them into other useful products. This process helps save energy, reduce environmental pollution, and achieve the recycling of resources.

[0003] In the prior art, when the filtering and separation equipment used for industrial waste oil regeneration is in use, the filter screen is very easy to be clogged due to the large amount of impurities contained in the waste oil, and frequent shutdowns are required for filter screen replacement and cleaning, which reduces the filtering and separation efficiency of industrial costs and also limits the development of the industrial waste oil regeneration industry. At the same time, the existing equipment usually uses a single filter element to filter and separate large particle impurities in industrial waste oil, which has a high risk of filter element clogging and is difficult to achieve fine filtration treatment of industrial waste oil.

[0013] Description: By sliding the cleaning plate onto the sliding seat, the cleaning plate can move synchronously when the thickness of the flexible filter on the reel increases; and the setting of the damping spring can keep the cleaning plate always close to the flexible filter, thereby improving the cleaning effect of the flexible filter.

[0014] Furthermore, an air inlet channel is provided inside the reel, and a plurality of air jet holes are evenly distributed on the side wall of the reel and are respectively connected to the air inlet channel; a high-pressure air nozzle is provided on the side wall of the cleaning cylinder and is rotatably connected to the end of the reel and is connected to the air inlet channel;

[0015] Description: When in use, the external high-pressure air source is introduced into the air intake channel through the high-pressure air nozzle, and the high-pressure airflow is sprayed to the flexible filter through the air jet hole, which can realize the high-pressure spray cleaning of the flexible filter, further improving the cleaning effect and use reliability of the flexible filter.

[0016] Furthermore, three filter element assemblies are provided, and the three filter element assemblies are arranged in parallel up and down inside the equipment box, and the mesh diameters of the flexible filter screens of the three filter element assemblies decrease from top to bottom; the number of cleaning assemblies corresponds to the number of filter element assemblies;

[0017] Description: By setting three flexible filter screens with different apertures, the utility model can perform three-stage filtration treatment on industrial waste oil, thereby improving the filtration accuracy of industrial waste oil and reducing the risk of clogging of the flexible filter screen.

[0018] The working principle of the utility model is:

[0019] When in use, industrial waste oil is introduced into the equipment box through the oil inlet pipe. When the waste oil flows through the flexible filter, impurities in the waste oil are filtered, and the filtered waste oil is discharged through the oil discharge pipe; the cleaning motor is used to drive the second sprocket to rotate forward, so that the two first sprockets drive the corresponding reels to rotate forward, so that the flexible filter is rolled up on one of the reels. During the movement of the flexible filter, the cleaning brush head on the cleaning plate inside the corresponding cleaning cylinder is used to clean the pollutants attached to the surface of the flexible filter. The cleaned pollutants fall to the bottom of the cleaning cylinder, and the movable cover is opened for cleaning; the cleaning motor is controlled to drive the second sprocket to reverse, so that the flexible filter is rolled up on another reel, and the cleaning brush head on the cleaning plate inside the corresponding cleaning cylinder is used to clean the pollutants attached to the surface of the flexible filter again; the above operations are repeated until the flexible filter recovers the normal filtering effect.

[0020] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0021] First, the utility model has a reasonable structural design. The cleaning motor is used to drive the flexible filter to move back and forth inside the equipment box, and two cleaning brushes are used to repeatedly clean the pollutants attached to the surface of the flexible filter. This is not only conducive to improving the cleaning efficiency of the flexible filter, but also enables the utility model to achieve the regeneration of industrial waste oil without stopping the machine, thereby improving the treatment efficiency of industrial waste oil.

[0022] Second, the utility model uses three flexible filter screens with different apertures to perform three-stage filtration treatment on industrial waste oil, thereby improving the filtration accuracy of industrial waste oil and thus improving the secondary utilization rate of industrial waste oil; at the same time, compared with a single filter screen, the utility model can effectively reduce the clogging risk of the filter screen and the pressure on the filter screen, and has extremely high reliability in use;

[0023] Third, the utility model utilizes the combined action of the cleaning brush head and high-pressure gas to clean the flexible filter screen, thereby reducing the difficulty of cleaning pollutants on the flexible filter screen and improving the cleaning efficiency and cleaning effect of the flexible filter screen.
