Description

Technical Field

[0001] The invention relates to the technical field of gear pumps, in particular to an energy-saving gear pump with an intelligent flow regulation function. Background Art

[0002] A gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport liquid or increase its pressure. Its working principle is that through the rotation of the gears, a closed working cavity is formed in the pump body. As the gears rotate, the volume of the suction chamber and the discharge chamber changes, thereby achieving the effect of suction and discharge.

[0003] The gear pump is very prone to axial and radial movement, which in turn causes wear of the floating side plate. The debris generated by the floating side plate can easily have an adverse effect on subsequent docking equipment. In addition, the liquid inlet of the existing gear pump does not filter impurities, which can easily cause the gear pump to become clogged. Summary of the invention

[0025] A sliding groove is provided on the outer wall of the liquid outlet 114, and a sliding plate 46 is slidably installed in the sliding groove. The sliding plate 46 is sleeved on the liquid outlet 114, and two groups of coils 4 are respectively arranged at both ends of the sliding plate 46, and two groups of electrodes 41 are arranged opposite to each other. The two groups of coils 4 and the electrodes 41 are electrically connected to the control system; a first spring 47 is connected between the sliding plate 46 and the liquid outlet 114, and both ends of the first spring 47 are electrically connected to the control system.

[0026] The sieve plate 42 is a circular plate, and the sieve mesh 421 is arranged in the middle of the sieve plate 42. Intermediate shafts 422 are arranged at both ends of the sieve plate 42. The intermediate shaft 422 at one end of the sieve plate 42 is rotatably mounted on the liquid outlet 114 through a torsion spring. The torsion spring presses the intermediate shaft 422 on the liquid outlet 114, thereby pressing the sieve plate 42 on the liquid outlet 114. The intermediate shaft 422 at the other end of the sieve plate 42 passes through the liquid outlet 114 and is provided with an adjusting gear 423. One side of the adjusting gear 423 is meshed with an adjusting gear. The adjusting rack 424 is arranged on the sliding plate 46; the sieve plate 42 is provided with a limiting groove, in which a limiting plate 43 is slidably installed, and a magnetic material is arranged on the limiting plate 43, and the magnetic material is directly opposite to the coil 4.

[0027] Working principle: Press the start button on the control panel 1, the gear pump starts, the driving motor 2 drives the driving gear 12 to rotate, the driving gear 12 drives the driven gear 13 to rotate, and the liquid is sucked from the liquid inlet 113 through the meshing of the driving gear 12 and the driven gear 13. Then, as the driving gear 12 and the driven gear 13 continue to rotate, the liquid is discharged from the liquid outlet 114; When the liquid enters the liquid inlet 113, the liquid drives the conical disk 31 to rotate through the arc blades 312, and filters the impurities in the liquid through the second filter screen 311. The conical disk 31 throws part of the liquid and impurities into the guide port 302, and part of the liquid and impurities enter the filter cartridge 3 through the guide port 302. The impurities are filtered again by the first filter screen 301 in the filter cartridge 3, and the impurities are deposited in the filter cartridge 3. After passing through the first filter screen 301, part of the liquid returns to the liquid outlet 114 from the guide port 303 again, and merges with most of the liquid after passing through the second filter screen 311. The merged liquid will contact the driving gear 12 and the driven gear 13, and be transported to the liquid outlet 114 through the driving gear 12 and the driven gear 13.

[0028] The floating side plate 115 is inevitably worn during actual use. Therefore, it is necessary to filter the debris generated by the wear of the floating side plate 115 to ensure that there is no interference with the subsequent docking equipment. The liquid and the debris are transported to the liquid outlet 114 through the driving gear 12 and the driven gear 13. The liquid and the debris are filtered by the screen 421. The debris is deposited on the screen 421. After the liquid passes through the screen 421, it is discharged from the liquid outlet 114 to achieve the filtering of the debris. During the liquid delivery process at the liquid outlet 114, the control system energizes the first spring 47, and each turn of the first spring 47 generates a magnetic field that attracts each other. The magnetic field compresses the first spring 47, causing the first spring 47 to shorten as a whole. The first spring 47 pulls the sliding plate 46 to move rightward, and the sliding plate 46 drives the two sets of coils 4 to move rightward, so that the two sets of coils 4 and the two sets of electrodes 41 are close to each other. When the two groups of coils 4 and the two groups of electrodes 41 are close to each other, the displacement sensor on the sliding plate 46 feeds back the displacement data to the control system. The control system connects the two groups of coils 4 to the circuit to generate a stable magnetic field through the two groups of coils 4. The liquid cuts the magnetic flux lines within the magnetic field of the two groups of coils 4, thereby generating an induced electromotive force on the two groups of electrodes 41. The control system processes and calculates the induced electromotive force to obtain flow data. The control system adjusts the flow of the gear pump according to the flow data to realize intelligent flow regulation of the gear pump.

[0029] When the gear pump works for the set time, the screen 421 needs to be cleaned. At this time, the buzzer in the control panel 1 will alarm, and the staff will connect the liquid outlet 114 to the external waste liquid bucket. At the same time, the control system will cut off the power of the first spring 47. After the first spring 47 is cut off, it gradually becomes longer under the action of its own elastic force. The first spring 47 pushes the sliding plate 46 to move to the left. The sliding plate 46 drives the adjustment rack 424 and the two sets of coils 4 to move to the left synchronously. The adjustment rack 424 moves to the left and meshes with the adjustment gear 423. The adjustment rack 424 brings The movable adjustment gear 423 rotates 90 degrees, and the adjustment gear 423 drives the screen plate 42 to rotate 90 degrees through the intermediate shaft 422, and the screen plate 42 drives the screen mesh 421 to rotate 90 degrees. After that, the control system connects the coil 4 close to the limiting plate 43 to the circuit, so that the magnetic field generated by the coil 4 and the magnetic material on the limiting plate 43 attract each other. Under the action of the attraction, the limiting plate 43 moves upward and compresses the reset spring. After that, the control system cuts off the power to the coil 4 close to the limiting plate 43, and the reset spring is released, and the reset spring pushes the limiting plate 43 to move downward; During the up and down movement of the limiting plate 43, the limiting plate 43 pulls the blocking block 44 to vibrate up and down through the elastic rope 45, and the blocking block 44 causes the screen 421 to vibrate, causing the debris on the screen 421 to fall off. The control system continuously powers on and off the coil 4 close to the limiting plate 43, thereby causing the screen 421 to vibrate, thereby achieving the purpose of cleaning the debris. The debris generated after cleaning is transported to the waste liquid barrel from the liquid outlet 114 along with the liquid.
