Description

A device for ultrasonic cleaning of pipes (hereinafter, also a utility model, technical solution, device) relates to devices for cleaning pipes of various diameters, from internal solid deposits; It can be used in a variety of fields. Deposits on the walls of pipes of water supply and water treatment systems in the form of a hard and hard to remove layer due to the content of mineral salts in the water, mainly magnesium and calcium, are the most common problem encountered in industry and in everyday life. As a result, there is a narrowing of the inner diameter of the pipes. The device is structurally related to products based on the physical (non-reagent) method - the method of ultrasonic cleaning. Designed for continuous sequential cleaning by moving the source of acoustic vibrations relative to the surface being cleaned.

Currently, the prior art utility model is known as "High-frequency ultrasonic emitter for technological cleaning (options)", taken as a prototype (RF patent No. 60791, priority date: 11/7/2006). Among the disadvantages of the prototype can be attributed to the fact that this device is placed on the surface to be cleaned stationary, which makes it impossible to quickly use it as a hand tool for cleaning a large area of the contaminated surface. Also, a certain disadvantage of the prototype is the absence of direct contact between the source of acoustic vibrations and the surface being cleaned, which negatively affects the effectiveness of the cleaning process and entails the need to use additional chemicals (liquids) in the cleaning process. The technical goal (task) of the claimed utility model is to eliminate the above disadvantages, and its technical result is the creation of a mobile device, simplified in design and operation, structurally designed for use as a hand tool, which provides more thorough cleaning without the use of additional chemicals (liquids) .

The task is achieved in that, in the claimed technical solution, which includes a frequency generator, electrically connected to an ultrasonic transducer-nozzle - the latter is structurally equipped with a through hole along its axis, while it is detachable, the frequency generator and the ultrasonic transducer-nozzle are placed in a single housing on which the device’s controls are located, while the device is movable relative to the surface being cleaned (essential signs are marked in bold heat models that distinguish it from the prototype). It is the above set of features that provides the claimed claimed utility model of the specified technical result.

The drawing (Fig.) Shows a schematic diagram of a device.

A device for ultrasonic cleaning of pipes includes the following elements: a housing (not shown conventionally), a frequency generator 1, an ultrasonic transducer-nozzle 2.

The case (conditionally not shown) is a bearing, of complex shape, hollow inside. Contains the controls of the utility model as a whole. Made with the ability to move along the surface to be cleaned.

The frequency generator 1 is stationary mounted inside the housing (not shown conventionally). It is electrically connected to an ultrasonic transducer-nozzle 2. It has a power supply line from an external source of electric energy of 220-240 V. It is structurally designed to convert the energy received from an external power source into periodic electrical oscillations of various shapes and frequencies. It can be represented by any known construction.

The ultrasonic transducer-nozzle 2 is movable, detachable, installed inside the housing (not shown conditionally). Electrically connected to frequency generator 1. Structurally designed to convert electrical vibrations supplied to it into mechanical ones of the same frequency (within 20,000 Hz). It can be represented by any known construction. It is installed around the pipe being cleaned 3, completely covering it from all sides. Allows linear and angular movements along the surface being cleaned.

The inventive utility model works as follows: under the influence of a frequency generator 1 in an ultrasonic transducer-nozzle 2, mechanical vibrations of a given frequency are excited. Due to the continuous contact of the latter with the surface being cleaned (from all its sides), acoustic vibrations are simultaneously excited over the entire surface of the pipe 3 being cleaned and in the water flowing at the place where the ultrasonic transducer-nozzle 2 is installed on the pipe 3. the action of various nonlinear effects (cavitation, etc.) arising in a liquid under the influence of powerful ultrasonic vibrations. It turns out inside the metal pipe 3 and inside the water creates constant micro-oscillations of a given amplitude. For the metal of which the pipe is made, such an amplitude is safe, but the layer of solid deposits does not withstand such an impact. Due to this, the bending vibrations of ultrasound gradually remove solid deposits from the walls of the surface being cleaned, which, under the influence of acoustic waves, gradually begin to exfoliate and to be washed out by the flow of water flowing through the pipe 3.

After a certain time, the device operator, acting on the controls installed on the case (not shown conditionally) moves it to a new place along the surface being cleaned. And so on until the end of the pipe being cleaned 3.

Currently, the applicant, on his own, made a prototype that showed its good performance.
