Description

Technical Field

[0001] The present invention relates to the technical field of sludge transportation, and specifically to a sludge pumping device. Background Art

[0002] A dredger is responsible for dredging the silt in waterways and rivers so that other ships can pass smoothly. The silt dug out by the dredger will be pumped and transferred by a piston pump truck. When the pressure oil of the hydraulic system of the piston pump truck enters the main oil cylinder, the piston rod extends, and at the same time, the pressure oil in the connecting pipe of the sealing circuit causes the other piston rod to retract; when the piston rod of the main oil cylinder retracts, the sludge conveying piston also retracts, generating a self-priming effect in the conveying cylinder. The sludge in the hopper is sucked into the conveying cylinder through the slide valve suction port under the action of atmospheric pressure and the boosting action of the stirring blades; under the action of oil pressure, the other main oil cylinder pushes the piston rod to extend and pushes the sludge piston to press out the sludge in the conveying cylinder, and enters the sludge conveying pipe through the slide valve conveying port; after the action is completed, the system automatically changes the direction to make the pressure oil enter the other main oil cylinder, completing the suction and delivery strokes of another different conveying cylinder; repeating like this, the sludge in the hopper is continuously sucked and pressed out of the conveying cylinder, and reaches the working point through the pipeline, completing the pumping operation.

[0003] The existing sludge piston pump truck will install a filter grille above the hopper to filter out larger stones in the sludge to avoid the pump cylinder being stuck or damaged by the stones. However, when the piston pump truck pumps some relatively viscous sludge, due to the large viscosity of the viscous sludge, its fluidity through the filter grille is poor, resulting in the slow speed of the viscous sludge entering the hopper through the filter grille, affecting the pumping efficiency of the pump for the sludge. Personnel need to use a shovel to stir the sludge on the filter grille to assist the sludge to fall into the hopper. However, since the sludge will adhere to the shovel and increase the weight of the shovel, it is more laborious and slower for personnel to assist the sludge to pass through the filter grille with the shovel.

The cap pins 42 are used to prevent the baffle 38 from detaching from the mudguard 4.

[0031] Working principle: In the process of the piston pump truck transferring the sludge dredged by the dredger, the sludge needs to pass through the inclined grid plate 3 to filter out larger stones inside before entering the hopper 2. In the process of the inclined grid plate 3 filtering the sludge, the dual-axis motor 8 drives the cam 10 to rotate through the rotating shaft 9. During the rotation, the cam 10 will lift the right end of the inclined grid plate 3 through the roller 7. When the cam 10 passes through the straight-edge notch 11 and leaves the roller 7, the inclined grid plate 3 will hit the hopper 2 under the action of gravity, and can vibrate and shake off the viscous sludge on the inclined grid plate 3, which is conducive to the viscous sludge quickly passing through the inclined grid plate 3 into the hopper 2, thereby improving the pumping efficiency of the piston pump truck for the viscous sludge. Moreover, since the inclined grid plate 3 is in an inclined state, when the right end of the inclined grid plate 3 swings back and forth, it is conducive to the stones automatically rolling off the inclined grid plate 3.

[0032] Since the inclined grid plate 3 is in a vibrating state during the process of pumping the sludge, and since there is sludge attached to the surface of the stones, some of the stones will be stuck in the through grooves of the inclined grid plate 3 during the reciprocating swing of the inclined grid plate 3. After the sludge pumping is completed, the servo motor 22 drives the first gear 20 and the threaded rod 18 to rotate through the second gear 21. The threaded rod 18 rotates through the second connecting seat 16 to drive the mounting shaft 12 and the multiple hooks 14 to reciprocate left and right on the inclined grid plate 3. During the process of the mounting shaft 12 moving to the left, the rack 26 will drive the mounting shaft 12, that is, the multiple hooks 14 to rotate clockwise through the third gear 23. During the process of the multiple hooks 14 moving to the left and rotating clockwise in the through groove of the inclined grid plate 3, the stones stuck in the through grooves of the inclined grid plate 3 can be lifted upwards, that is, the stones stuck on the inclined grid plate 3 can be picked out, and the inclined grid plate 3 can be dredged.

[0033] After the inclined grid plate 3 is dredged, the servo motor 22 drives the threaded rod 18 to rotate in the opposite direction, so that the multiple hooks 14 move back to the right end near the inclined grid plate 3. Then, the operator pushes the hexagonal column 29 to the left through the dial ring 31 to separate the hexagonal column 29 from the sleeve 30, so that the servo motor 22 does not swing with the inclined grid plate 3 during the reciprocating swing of the inclined grid plate 3 to shake off the sludge, thereby avoiding the servo motor 22 from being damaged by vibration, and effectively extending the service life of the servo motor 22. After the hexagonal prism 29 is moved a certain distance to the left, the hemispherical portion of the pin rod 33 will be inserted into the corresponding hemispherical slot 36 driven by the compression force of the first spring 35, so as to position the hexagonal prism 29 and prevent the hexagonal prism 29 from pressing against the sleeve 30 during the reciprocating swing of the inclined grid plate 3. After the hexagonal prism 29 is moved and inserted into the sleeve 30, the pin rod 33 will also be inserted into the corresponding hemispherical slot 36 to prevent the hexagonal prism 29 from detaching from the sleeve 30 during the rotation of the hexagonal prism 29 driven by the first gear 20.

[0034] During the reciprocating swing of the inclined grid plate 3, the inclined grid plate 3 will abut against the lower end of the baffle plate 38 and drive the baffle plate 38 to move upward. When the inclined grid plate 3 rotates downward, the baffle plate 38 will move downward and reset under the driving force of the compressed elastic force of the second spring 41, that is, the lower end of the baffle plate 38 can always be movably attached to the inclined grid plate 3, which is beneficial to the baffle plate 38 to block the avoidance port 37 on the mudguard 4 and can prevent sludge from splashing into the piston pump chassis 1 through the avoidance port 37.
