Description

Technical Field

[0001] This utility model relates to non-contact flow detection, specifically a non-contact flow detection device for oil supply in a flotation machine. Background Technology

[0002] The flotation machine's lubrication pipeline needs to monitor changes in the lubrication volume. Currently, instruments are installed by drilling holes in the pipeline, but this compromises the pipeline's stability. Installing instrument probes inside the pipeline also increases internal pressure and makes them susceptible to corrosion by the pipeline fluid. Utility Model Content

[0003] To address the shortcomings of the existing technology, this invention provides a non-contact flow detection device for oil supply in flotation machines. This invention features an ultrasonic receiver and transmitter, which are mounted on the outer wall of the pipeline using two brackets, forming a non-contact detection method with high accuracy and without affecting the internal conditions of the pipeline.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a non-contact flow detection device for oil supply in a flotation machine, comprising a bracket installed on the oil supply pipeline of the flotation machine, the bracket comprising two sub-brackets, each sub-bracket comprising a semi-circular clamp, the semi-circular clamp being provided with a connecting part and an mounting part, the two sub-brackets being respectively disposed on both sides of the oil supply pipeline of the flotation machine and being fastened together by the connecting part, the mounting parts of the two sub-brackets being respectively equipped with an ultrasonic transmitter and an ultrasonic receiver.

[0005] The connecting part includes a short plate and a long plate. The short plate is fixed to one end of the semi-circular clamp along the axial direction, and the long plate is fixed to the other end of the semi-circular clamp along the axial direction. The short plate of the first sub-support can be fixedly connected to the long plate of the second sub-support.

[0006] The short plate has a first hole, and the long plate has a second hole. The first hole and the second hole are connected by bolts.

[0007] The short plate has the same axial length as the semi-circular clamp, and the length of the long plate is much greater than the length of the short plate.

[0008] The mounting part adopts a mounting base, the semi-circular clamp has a mounting hole, the mounting base is installed in the mounting hole, and the ultrasonic transmitter and the ultrasonic receiver are installed on the mounting base.

[0009] The inner wall of the semi-circular clamp is provided with an anti-slip pad.

[0010] In summary, this utility model achieves the following technical effects:

[0011] This application adds an ultrasonic transmitter and receiver to the oil filling pipeline of the flotation machine. Each is fixedly installed using a sub-support. The two sub-supports can be connected and fixed to each other, thus holding the pipeline tightly to achieve non-contact flow detection. The installation distance between the two sub-supports can be adjusted to adjust the distance between the transmitter and receiver, making it suitable for various situations.

[0012] This invention features an ultrasonic receiver and transmitter, which are mounted on the outer wall of the pipeline using two brackets to form a non-contact detection method with high accuracy and without affecting the internal condition of the pipeline. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Example:

[0023] Figure 1 This is a non-contact flow detection device for oil supply in a flotation machine, comprising a bracket 1 installed on the oil supply pipeline 2 of the flotation machine. The bracket 1 includes two sub-brackets 11, each sub-bracket 11 including a semi-circular clamp 111. The semi-circular clamp 111 is provided with a connecting part and an installation part. The two sub-brackets 11 are respectively located on both sides of the oil supply pipeline 2 of the flotation machine and are fastened together by the connecting part. The installation parts of the two sub-brackets 11 are respectively equipped with an ultrasonic transmitter 3 and an ultrasonic receiver 4.

[0024] This application adds an ultrasonic transmitter 3 and a receiver 4 to the oil filling pipeline 2 of the flotation machine. Each is fixedly installed using a sub-support 11. The two sub-supports can be connected and fixed to each other, thus holding them tightly on the pipeline 2 to achieve non-contact flow detection. The installation distance between the two sub-supports can be adjusted to adjust the distance between the transmitter and receiver, which is suitable for various situations.

[0025] The ultrasonic transmitter 3 and ultrasonic receiver 4 transmit signals to the intelligent controller, which is located in the field control room. The flow sensor transmits dynamic information about the oil supply to the flotation machine. Based on the data detected by the flow sensor, the intelligent controller automatically performs logical calculations to derive the real-time and cumulative flow values. This invention automatically measures the oil supply to the flotation machine, avoiding common problems such as sensor clogging and corrosion caused by direct contact with the oil medium, and is energy-saving and environmentally friendly.

[0026] Figure 2 This is a schematic diagram of a bracket. The connecting part includes a short plate 114 and a long plate 116. The short plate 114 is fixed to one end of the semi-circular clamp 111 along the axial direction, and the long plate 116 is fixed to the other end of the semi-circular clamp 111 along the axial direction. The short plate 114 of the first sub-bracket 11 can be fixedly connected to the long plate 116 of the second sub-bracket 11.

[0027] The short plate 114 has a first hole 115, and the long plate 116 has a second hole 117. The first hole 115 and the second hole 117 are connected by bolts.

[0028] The short plate 114 has the same axial length as the semi-circular clamp 111, while the long plate 116 is much longer than the short plate 114. This allows for adjustment of the installation distance, enabling the change of the distance between the receiver and transmitter, thus facilitating the adjustment of the ultrasonic signal.

[0029] This invention features two identical sub-supports arranged symmetrically at the center, allowing them to securely connect and fasten together after the pipeline is tightly held. The connection part uses a long and short plate structure, enabling adjustment of the installation distance and changing the distance and angle between the transmitter and receiver. When the transmitter or receiver is damaged, the support can be removed without affecting the use of the pipeline.

[0030] The mounting part adopts a mounting base 118, and the semi-circular clamp 111 has a mounting hole 113. The mounting base 118 is installed in the mounting hole 113, and the ultrasonic transmitter 3 and the ultrasonic receiver 4 are installed on the mounting base 118.

[0031] Filler blocks 5 can also be provided on the end faces of the receiver and transmitter. The filler blocks 5 fit together with the pipe 2, so that there are no gaps between the receiver and transmitter and the pipe, and no signal interference such as air.

[0032] The inner wall of the semi-circular clamp 111 is provided with an anti-slip pad 112. The anti-slip pad 112 has a hole aligned with the mounting hole 113 for the transmitting and receiving ends to pass through.

[0033] Figure 3 This is a diagram illustrating the change in installation distance.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
