Description

Technical Field

[0001] The invention relates to the technical field of sewage pump delivery pipelines, in particular to a low-water-level vertical and horizontal dual-purpose explosion-proof sewage pump delivery pipeline structure. Background Art

[0002] Sewage pumps are divided into vertical and horizontal types according to the installation orientation. Sewage pumps are widely used in the discharge and treatment of industrial sewage. Sewage pumps generate suction force through the impeller to allow external sewage to flow in the delivery pipeline. In order to prevent sand and stone particles in the sewage from entering the pump and causing blade loss, a filtering structure is installed in the delivery pipeline to filter the sewage. However, there are still some problems with the existing sewage pump delivery pipeline: The existing sewage pump delivery pipeline is not equipped with an explosion-proof detection mechanism. When the external water level is too low, the pump will continue to run, causing the pump to be in a high-temperature idling state for a long time, thereby increasing the risk of pump burnout. In addition, it is difficult to effectively clean the filter structure during the use of the pipeline. After the pump has been running for a long time, the filter structure of the pipeline is prone to blockage, thereby reducing the pumping efficiency.

[0023] Working Principle: When using the low water level vertical and horizontal dual-purpose explosion-proof sewage pump delivery pipeline structure, first refer to Figures 1-16The pump 2 can be set in two states: vertical and horizontal. The extension tube 33 of the device enters the sewage and presses the slide bar on the top of the upper trigger plate 7. At this time, the upper trigger plate 7 will move toward the controller 4, so that the electrode head on the upper trigger plate 7 can enter the controller 4. At this time, the control current in the power supply 13 can enter the pump 2 through the upper trigger plate 7 and the controller 4. At this time, the pump 2 will start to discharge sewage. At the same time, the guide column on the upper trigger plate 7 will move on the rubber ring in the controller 4. At this time, the water discharged by the pump 2 will enter the discharge pipe 3, and the high-pressure water flow will drive the inner column 1401 to rotate through the force plate 1402. The inner column 1401 will drive the transmission gear 12 to rotate synchronously. At this time, the transmission gear 12 will drive the gear plate 11 to move upward, and the gear plate 11 will pass through the push rod 9 drives the lower trigger plate 8 to move, and at the same time the push rod 9 compresses the return spring 10. The guide column and the electrode head on the lower trigger plate 8 will first enter the controller 4. After the lower trigger plate 8 continues to move upward, the push column on the lower trigger plate 8 will push up the guide column on the upper trigger plate 7, so that the electrode head on the upper trigger plate 7 leaves the controller 4. At this time, the controller 4 will be completely powered by the lower trigger plate 8. When the external water level is too low, the force plate 1402 will not be able to rotate. At this time, the reset effect of the return spring 10 and the weight of the push rod 9 will drive the tooth plate 11 to move downward and return to its original position. The lower trigger plate 8 on the top of the push rod 9 will synchronously move away from the controller 4. The controller 4 will no longer be powered, causing the pump 2 to shut down, thereby preventing the pump 2 from idling when the water level is too low, so as to reduce the risk of the pump 2 burning due to idling and high temperature operation; During the drainage process of the pump 2, the force-bearing plate 1402 will drive the inner column 1401 to rotate, and the liquid in the discharge pipe 3 will enter the liquid storage tank on the force-bearing plate 1402 through the liquid inlet mesh plate 1403. When the force-bearing plate 1402 enters the interior of the closed cover 6, the liquid inlet mesh plate 1403 on the force-bearing plate 1402 will contact the inner wall of the closed cover 6 to form a closed structure. When the force-bearing plate 1402 drives the extrusion slide 1404 to move toward the guide plate 15, the extrusion slide 1404 will start to move under the resistance of the guide plate 15, and the extrusion slide 1404 will press the liquid in the force-bearing plate 1402 toward the moving The liquid in the infusion channel on the plug rod 1405 flows into the fixed cylinder 16 through the inner column 1401. When the extrusion slide 1404 moves away from the guide plate 15, the extrusion slide 1404 will be reset under the action of the rotating centrifugal force, and the liquid in the fixed cylinder 16 will flow into the liquid storage cylinder 27 through the second infusion tube 23. At this time, the liquid will push the moving plug rod 28 in the liquid storage cylinder 27 to move, and the liquid on the other side of the liquid storage cylinder 27 will enter the return pipe 21 through the first infusion tube 22 and the return channel 19. The liquid in the return pipe 21 will flow back into the discharge pipe 3. During this process, the servo motor 18 The control plug 17 will be driven to rotate 180 degrees according to the time period, and the return channel 19 and the liquid inlet channel 20 on the control plug 17 will be swapped. From the above steps, it can be seen that the moving plug rod 28 will move back and forth in the liquid storage cylinder 27. When the moving plug rod 28 drives the inner core rod 26 away from the liquid storage cylinder 27, the inner core rod 26 can extend from the second filter cover 25. The inner core rod 26 will clean the filter mesh inside the second filter cover 25. The inner core rod 26 will drive the second filter cover 25 to move through the first insert 29, so that the second filter cover 25 cleans the filter mesh inside the first filter cover 24. The outer cleaning frame 32 will be reset synchronously when the moving plug rod 28 drives the inner core rod 26 to reset, and the first filter cover 24 and the second filter cover 25 will perform the cleaning operation synchronously, and the outer cleaning frame 32 will be reset synchronously.
