Description

Technical Field

[0001] The utility model relates to the technical field of radar level gauges, and particularly relates to a cleaning tool for a radar level gauge. Background Art

[0002] A radar level gauge is a measuring instrument based on the time travel principle. The radar wave travels at the speed of light, and the running time can be converted into a level signal by electronic components. The probe emits high-frequency pulses that propagate in space at the speed of light. When the pulse encounters the surface of the material, it is reflected back and received by the receiver in the instrument, and the distance signal is converted into a level signal.

[0003] In the prior art, when a radar level gauge is used in a slag material working condition or a working condition where water mist is easily formed, with the continuous operation of the device process, the signal emission and reception surfaces of the radar level gauge are easily attached with materials or form water droplets on the surface, which affects the signal reception of the radar level gauge. The radar level gauge frequently has abnormalities and alarms. When alarms occur due to signal interference, it cannot be solved online and can only wait for the device to stop to carry out fault and abnormality handling. However, the shutdown process of continuous operation equipment or devices is cumbersome and time-consuming, resulting in a long non-production time and affecting actual production.

[0025] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0026] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection, an electrical connection, or a communication connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication between two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0028] As Figure 1 shown, the present utility model discloses a cleaning tooling for a radar level gauge, which includes an annular fixing ring 1. Three nozzles 2 are provided on the inner wall of the fixing ring 1, and the three nozzles 2 are arranged at equal intervals in the circumferential direction of the inner wall of the fixing ring 1.

[0029] The fixing ring 1 is arranged in the storage tank where the radar level gauge is located. A support rod (not shown in the figure) for connecting with the storage tank is provided on the fixing ring 1. The fixing ring 1 is located below the radar level gauge. The bottom of the radar level gauge is a signal transmitting and receiving surface, which is circular. The fixing ring 1 and the signal transmitting and receiving surface are in a coaxial state. The inner diameter of the fixing ring 1 is larger than the outer diameter of the signal transmitting and receiving surface to prevent the fixing ring 1 from obstructing the signal transmission and reception of the radar level gauge.

[0030] The nozzle 2 is flat, and the water outlet at the end of the nozzle 2 is oblong (a shape with a rectangle in the middle and semi-circles at both ends). The nozzle 2 is arranged obliquely, and the nozzle 2 forms an angle of 45° with the horizontal plane. The cleaning medium sprayed out from the water outlet of the nozzle 2 flushes the signal transmitting and receiving surface at the bottom of the radar level gauge.

[0031] A buffer equalizing pipe 5 is arranged outside the storage tank. Cleaning medium pipelines 3 are respectively communicated between the three nozzles 2 and the buffer equalizing pipe 5, and a cleaning valve 4 is provided on the cleaning medium pipeline 3. A cleaning medium main pipeline 6 and a drain pipe 8 are also communicated with the buffer equalizing pipe 5. A main pipeline valve 7 is provided on the cleaning medium main pipeline 6, and a drain valve 9 is provided on the drain pipe 8.

[0032] When the radar level gauge needs to be cleaned, open the main pipe valve 7. The cleaning medium enters the ring tooth pressure equalizing pipe from the cleaning medium main pipe 6, and then open the cleaning valve 4. The cleaning medium is input into the nozzle 2 from the cleaning medium pipeline 3, and finally sprays out from the water outlet of the nozzle 2 to wash the signal transmitting and receiving surface at the bottom of the radar level gauge, washing the attached materials or dripping liquid. Each nozzle 2 is controlled by a separate cleaning valve 4 for liquid output, and the liquid spraying directions of each valve are different. The cleaning medium is sprayed in different directions through the three nozzles 2 to improve the cleaning effect of the radar level gauge, clean the signal transmitting and receiving surface at its bottom, and avoid the signal transmission and reception of the radar level gauge from being affected. The residual liquid in the tooling can be discharged through the drain valve.

[0033] The utility model realizes the on-line cleaning of the radar level gauge. The signal transmitting and receiving surface of the radar level gauge is washed and cleaned through the nozzle 2, washing the attached materials and dripping liquid, avoiding the signal transmission and reception of the radar level gauge from being affected. The cleaning operation is carried out on-line and there is no need to stop the device, avoiding affecting the production operation.

[0034] The above embodiments are only the preferred embodiments of the utility model, and do not limit the technical solutions of the utility model. As long as the technical solutions that can be realized on the basis of the above embodiments without creative labor shall be regarded as falling within the scope of the patent rights of the utility model.
