Abstract
Description
Technical Field
[0001] This utility model belongs to the field of slurry pump technology, specifically relating to a slurry pump short circuit. Background Technology
[0002] Slurry pumps are large centrifugal pumps primarily used to transport media containing abrasive solid particles. They are indispensable general-purpose equipment in industries such as mining, chemical, coal, and metal smelting. A slurry pump connector is a short pipe installed between the pump's inlet and outlet. As a crucial component connecting the pump body and the connector itself, it ensures a smoother and more natural transition between the two, preventing rapid fluid changes and thus improving flow stability and throughput, ultimately increasing pump efficiency and reducing energy consumption.
[0003] Because the slurry pump transports a lot of solid particles, some of which are large in diameter, and because the slurry generally has strong coagulation properties, these particles can easily cause short circuits to become blocked, which in turn can lead to the slurry pump not discharging or discharging poorly during operation. Utility Model Content
[0004] This utility model provides a short-circuit for a slurry pump to solve the technical problem of easy clogging in existing slurry pump short-circuit connections.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A slurry pump short circuit includes a short circuit body, on which a blockage removal mechanism is provided. The blockage removal mechanism includes a plurality of mounting slots axially arranged around the outside of the short circuit body. An ultrasonic transmitter is provided on the inner side of each mounting slot, and the signal transmitting end of the ultrasonic transmitter faces the inner side of the short circuit body.
[0007] Preferably, the inner side of the shorting body is provided with a particle concentration monitoring mechanism electrically connected to the ultrasonic transmitter. The particle concentration monitoring mechanism includes a plurality of capacitive phase concentration sensors arranged axially around the inner side of the shorting body. The particle concentration detection mechanism is located between the outlet of the shorting body and the blockage removal mechanism.
[0008] Preferably, there are two particle concentration detection mechanisms, one of which is located between the inlet of the short-circuit body and the blockage removal mechanism, and the other is located between the outlet of the short-circuit body and the blockage removal mechanism.
[0009] Preferably, the particle concentration monitoring mechanism further includes a mounting groove disposed on the inner annular surface of the shorting body and near the end of the shorting body. A mounting ring coaxial with the shorting body is installed inside the mounting groove, and the capacitive phase concentration sensor is evenly distributed and installed around the inner side of the mounting ring. A clamping plate is also installed inside the mounting groove, and the clamping plate is detachably connected to the mounting ring by a first bolt.
[0010] Preferably, a gasket is provided between the clamping plate and the mounting ring.
[0011] Preferably, the inner ring surface of the short-circuit body is covered with a wear-resistant lining.
[0012] Preferably, an end cap is detachably connected to the end of the mounting groove via a second bolt.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0014] 1. This device emits a predetermined ultrasonic wave through an ultrasonic transmitter. The ultrasonic transmitter provides uniform ultrasonic vibration to the short-circuit body, clearing the short-circuit body or preventing it from becoming blocked. This prevents the short-circuit from becoming blocked due to large-diameter solid particles in the fluid being transported by the pump, which have strong coagulation properties.
[0015] 2. This device can determine the blockage situation. Specifically, when the particle concentration monitoring mechanism at the outlet of the short-circuit body detects a blockage signal, it proves that a blockage has occurred inside the short-circuit body. At this time, the signal is fed back to the ultrasonic transmitter inside the short-circuit body, and the ultrasonic transmitter emits ultrasonic waves to clean the blockage. When the particle concentration monitoring mechanism at the inlet of the short-circuit body detects a blockage signal, it proves that a blockage has occurred inside the slurry pump body. At this time, the operator needs to perform a blockage clearing operation inside the slurry pump. Attached Figure Description

In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] The following is combined Figures 1-2 This utility model will be described in detail.
[0023] A slurry pump short circuit, in some embodiments, such as Figures 1-2 As shown, it includes a shorting body 1, which is provided with three blockage removal mechanisms. Each blockage removal mechanism includes four mounting slots 2 axially arranged around the outside of the shorting body 1. An ultrasonic transmitter 3 is provided on the inner side of each mounting slot 2, and the signal transmitting end of the ultrasonic transmitter 3 faces the inner side of the shorting body 1.
[0024] In practical use, the ultrasonic transmitter 3 emits a predetermined ultrasonic wave, which provides uniform ultrasonic vibration to the short-circuit body 1 to clear the short-circuit body 1 or prevent the short-circuit body 1 from becoming blocked, and to prevent the short-circuit from becoming blocked due to the large diameter of solid particles contained in the fluid transported by the pump body having strong coagulation properties.
[0025] In some embodiments, such as Figures 1-2As shown, the inner side of the shorting body 1 is provided with a particle concentration monitoring mechanism electrically connected to the ultrasonic transmitter 3. The particle concentration monitoring mechanism includes a plurality of capacitive phase concentration sensors 4 arranged axially around the inner side of the shorting body 1. The particle concentration detection mechanism is located between the outlet 6 of the shorting body 1 and the blockage removal mechanism.
[0026] In practical use, the capacitance output value changes with the flow of fluid within the short-circuit body 1. Due to the different dielectric constants of solid particles and fluid, when solid particles flow through the detection field formed by the capacitive phase concentration sensor 4, the composition of the fluid within the short-circuit body 1 begins to change, and the equivalent dielectric constant of the fluid also changes accordingly, thus causing the capacitance output value to change. The capacitance value output by the capacitive phase concentration sensor 4 is used as a measure of particle concentration within the short-circuit body 1. The capacitive phase concentration sensor 4 measures the solid phase volume fraction within the short-circuit body 1 and feeds the information back to the ultrasonic transmitter 3. The ultrasonic transmitter 3 emits a predetermined ultrasonic wave, and the ultrasonic sensor provides uniform ultrasonic vibration to the short-circuit body 1, clearing blockages or preventing blockages in the short-circuit body 1.
[0027] In some embodiments, such as Figures 1-2 As shown, there are two particle concentration detection mechanisms, one of which is located between the inlet 5 of the short-circuit body 1 and the blockage removal mechanism, and the other is located between the outlet 6 of the short-circuit body 1 and the blockage removal mechanism.
[0028] When the particle concentration monitoring mechanism at the outlet of the short-circuit body 1 detects a blockage signal, it proves that a blockage has occurred inside the short-circuit body 1. At this time, the signal is fed back to the ultrasonic transmitter 3 inside the short-circuit body 1, and the ultrasonic transmitter 3 emits ultrasonic waves to clean the blockage. When the particle concentration monitoring mechanism at the inlet of the short-circuit body 1 detects a blockage signal, it proves that a blockage has occurred inside the slurry pump body. At this time, the staff needs to perform a blockage clearing operation inside the slurry pump.
[0029] In some embodiments, such as Figures 1-2 As shown, the particle concentration monitoring mechanism further includes a mounting groove 7 disposed on the inner annular surface of the shorting body 1 and near the end of the shorting body 1. A mounting ring 8 coaxial with the shorting body 1 is installed inside the mounting groove 7. The capacitive phase concentration sensor 4 is evenly distributed and installed around the inner side of the mounting ring 8. A clamping plate 9 is also installed inside the mounting groove 7. The clamping plate 9 and the mounting ring 8 are detachably connected by a first bolt 10.
[0030] When the capacitive phase concentration sensor 4 needs to be repaired, the first bolt 10 is removed to remove the clamping plate 9, and then the mounting ring 8 is removed from the mounting groove 7 to facilitate the repair of the capacitive phase concentration sensor 4.
[0031] In some embodiments, such as Figures 1-2 As shown, an elastic pad 11 is provided between the clamping plate 9 and the mounting ring 8.
[0032] This avoids a rigid contact between the clamping plate 9 and the mounting ring 8, which would reduce the stability of the installation.
[0033] In some embodiments, such as Figures 1-2 As shown, the inner ring surface of the short-connector body 1 is covered with a wear-resistant inner lining 12.
[0034] The wear-resistant liner 12 is welded on the inner ring surface of the short-joint body 1 using YD888(Q) welding wire. The weld thickness is 5mm, and the hardness after welding is HRC60-65, thereby increasing the wear resistance of the inner ring surface of the short-joint body 1 and improving the service life of the short-joint body 1.
[0035] In some embodiments, such as Figures 1-2 As shown, the end of the mounting groove 2 is detachably connected to an end cap 14 via a second bolt 13.
[0036] Remove the second bolt 13, and then remove the end cap 14. At this point, the ultrasonic transmitter 3 can be removed from the mounting slot 2 for inspection.
[0037] In some other embodiments, such as Figures 1-2 As shown, unlike the above embodiment, the inner ring surface of the pressing plate 9 is also covered with a wear-resistant inner lining 12.
[0038] The operating principle of this device is as follows:
[0039] When the particle concentration monitoring mechanism at the outlet of the short-circuit body 1 detects a blockage signal, it proves that a blockage has occurred inside the short-circuit body 1. At this time, the signal is fed back to the ultrasonic transmitter 3 inside the short-circuit body 1, and the ultrasonic transmitter 3 emits ultrasonic waves to clean the blockage. When the particle concentration monitoring mechanism at the inlet of the short-circuit body 1 detects a blockage signal, it proves that a blockage has occurred inside the slurry pump body. At this time, the staff needs to perform a blockage clearing operation inside the slurry pump.
[0040] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
