Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more particularly to a bidirectional ultrasonic vibration plate, an explosion-proof device and a filter. Background Art

[0002] Hydration to produce cyclohexanol is a chemical production method primarily used to synthesize cyclohexanol from cyclohexane. Cyclohexanol is an important organic chemical raw material widely used in the production of nylon fibers, engineering plastics (such as polyamide), plasticizers, solvents, and other products. The catalyst filter is the primary equipment for the hydration reaction.

[0003] Chinese patent application number 201820475879.9 discloses a catalyst filter, which includes a cylinder, an upper head disposed at the upper end of the cylinder, a lower head disposed at the lower end of the cylinder, and a sealing flange for connecting the upper head and the cylinder. A row pipe is provided between the cylinder and the lower head, and the row pipe is composed of interconnected horizontal and vertical pipes. A plurality of microporous filter elements with one end closed are vertically mounted on the row pipe, and the microporous filter elements are connected to the row pipe. A connected cavity is formed between the upper head, the cylinder, and the lower head. A mother liquor inlet and a slag outlet are provided at the lower end of the lower head. The outlet of the row pipe extends out of the cylinder to form a filtered liquid outlet. A nitrogen inlet is provided on the upper head. This catalyst filter flushes the adhesions on the surface of the filter element through a spray device, thereby flushing them off the surface of the filter element to ensure the cleanliness of the filter element. However, the following problems still exist:

[0004] 1. The spray device relies entirely on the impact of water flow to clean the adhesions. The water flow has a certain impact effect only when it first contacts the adhesions. After that, it can only flow downward along the filter element. The ability to remove adhesions during flow is limited, so the adhesions at the bottom cannot be effectively cleaned. At the same time, the spray angle of the water flow is limited, and there will be dead corners, which cannot play a good cleaning role.

[0005] 2. Some filters are equipped with ultrasonic cleaning devices, etc. However, due to the state inside the filter, it is easy to cause leakage at the pipe connection outside the cable. At the same time, when the filter device is filled with high-temperature flammable and explosive media, there is a lack of devices that can detect it, which is not conducive to the safety of the equipment.

[0006] Therefore, it is necessary to propose a bidirectional ultrasonic vibration plate, an explosion-proof device and a filter to solve the above problems. Utility Model Content

[0007] In response to the above problems, the utility model provides a bidirectional ultrasonic vibration plate, an explosion-proof device and a filter; it has the function of efficiently cleaning the filter element, and at the same time can increase the sealing of the connection between the bidirectional ultrasonic vibration plate and the connecting pipe through a three-sealing structure.

The bidirectional ultrasonic vibration plates can emit ultrasonic waves to both sides, thereby cleaning the filter elements on both sides. Moreover, the ultrasonic waves emitted by two adjacent bidirectional ultrasonic vibration plates will come into contact, which can further enhance the cleaning effect. When the ultrasonic waves come into contact with the tank wall, they will rebound and continue to act on the filter element.

[0017] 2. This device is equipped with three sealing structures at the connection between the bidirectional ultrasonic vibration plate and the connecting pipe, which can effectively prevent liquid from leaking into the bidirectional ultrasonic vibration plate. At the same time, the extension at the bottom of the upper flange also improves the convenience of installation, making it easy to align it with the lower flange for installation.
