Description

Three-dimensional rotary nozzle for cleaning large-volume cylindrical tanks

technical field

The utility model belongs to the technical field of cleaning devices, and relates to a three-dimensional rotating nozzle for cleaning large-capacity cylindrical tanks used in coal chemical and petroleum enterprises.

Background technique

Methanol storage tanks in coal chemical enterprises and crude oil storage tanks in oil production plants have relatively large volumes, usually between 5000m ³ and 50000m ³ . Drying, anti-corrosion and other processes can be put into use, so as not to affect product quality; in addition, some storage tanks that have been put into use will also produce a lot of rust and scale after several years of use, so they must be cleaned frequently , to ensure product quality. However, due to the large volume of the above-mentioned storage tanks, they were cleaned by filling them with water in the past, which not only wastes chemicals, but also wastes a lot of precious water resources. It has caused great inconvenience, therefore, it is necessary to design an economical and environmentally friendly storage tank cleaning equipment that can save the amount of medicament and water.

Utility model content

The purpose of the utility model is to solve the problems existing in the prior art, to provide a cleaning device for a large-volume (more than 5000m ³ ) cylindrical tank body that is simple in structure, easy to operate, can greatly save medicaments and water resources, and has a good cleaning effect. Three-dimensional rotating nozzle.

The technical solution adopted for the purpose of the above invention is as follows: the provided three-dimensional rotary nozzle for cleaning the large-capacity cylindrical tank has a pair of cylinders consisting of an upper fixed plate, a lower fixed plate and a plurality of connecting screws between the plates. Cage-type fixed bracket, a vertical section of a T-shaped spray boom inside is inserted into the cylindrical cage-type fixed bracket along the center line from the top of the cylindrical cage-type fixed bracket, and the lower end of the vertical section of the T-shaped spray boom Penetrating into a liquid inlet pipe joint, the upper part of the vertical section of the T-shaped spray bar is connected with the upper fixed plate through a tapered bearing. Both ends of the straight section of the T-shaped spray bar are nozzle tubes, and the two nozzle tubes are opposite to each other. The straight rod sections are arranged in a circular arc with an arc of 45°, and the spraying direction is opposite. The lower part of the liquid inlet pipe joint is connected to the lower fixed plate through an interface flange.

The technical scheme adopted by the utility model also includes: a packing gland with a built-in sealing packing is press-fitted on the upper part of the liquid inlet pipe joint through fastening bolts.

The technical solution adopted by the utility model also includes: a fixed sleeve is installed on the upper part of the vertical section of the T-shaped spray rod, and the outer diameter of the fixed sleeve is consistent with the outer diameter of the rotating ring of the tapered bearing.

The technical solution adopted by the utility model also includes: the tapered bearing is a 50° tapered bearing.

In practical application, the three-dimensional rotary nozzle is set on the upper part of the inner space of a cylindrical tank with a size of more than ^5000m3 , and the height of the T-shaped spray bar is adjusted. The cleaning liquid delivery pipe of the high-pressure cleaning pump is connected to each other; after the cleaning pump is turned on, the pressurized cleaning liquid passes through the liquid inlet pipe joint, the vertical section of the T-shaped spray boom in turn, and then splits through the two straight sections of the T-shaped spray boom. The arc-shaped nozzle tube at the end is sprayed out. Since the nozzle tubes at both ends of the straight section of the T-shaped spray bar are arc-shaped with an arc of 45° and the spraying direction is opposite, the resulting reverse force can make the T-shaped spray bar continue to spray. Rotate, so that the cleaning liquid circulates and sprays evenly to the upper tank wall of the cylindrical tank body. The cleaning liquid then flows down from the tank wall and collects at the bottom of the tank, and then is pumped to the top of the tank through high-pressure cleaning. Clean the rust and scale on the inner surface of the storage tank.

The beneficial effects and structural advantages that the utility model has are:

1. The water consumption of cleaning a ^20000m3 storage tank by using the three-dimensional rotating nozzle described in the present invention is only 1% of the water consumption of the previous method of filling the storage tank;

2. The amount of chemicals used to clean a 20,000 m storage tank by using the ^three- dimensional rotary nozzle described in the present invention is only 1% of the amount of chemicals used in the previous way of cleaning the tanks;

3. Using the three-dimensional rotary nozzle described in the present invention to clean the ^20000m3 storage tank, the amount of pharmaceutical waste water is very small, only 1/100 of the original amount;

4. In the structure of the utility model, the nozzle tubes at both ends of the straight section of the T-shaped spray bar are arranged in a circular arc with a radian of 45° and the spraying direction is opposite. The resulting reverse force can make the T-shaped spray bar continuously rotate;

5. The utility model adopts the packing gland to seal the gap between the liquid inlet pipe and the T-shaped spray rod, which can prevent the cleaning liquid from leaking from the gap between the liquid inlet pipe and the T-shaped spray rod;

6. In the structure of the utility model, the resistance between the T-shaped spray bar and the upper fixed plate is reduced during the rotation process through the 50° conical bearing installed in the center of the upper fixed plate;

7. In the structure of the utility model, the outer diameter of the fixed sleeve is the same as the outer diameter of the rotating ring of the 50° tapered bearing, so that the T-shaped spray bar and the 50° tapered bearing rotate together, reducing the T-shape during the rotation process. Resistance during boom rotation with 50° tapered bearing.
