Description

Technical Field

[0001] This utility model relates to the field of drainage tools technology, specifically a practical tank truck water pumping device. Background Technology

[0002] When cleaning sludge from water pools and sedimentation tanks in coal mines, the sludge is typically transferred into coal tankers. After a period of settling, water will accumulate on the surface of the fully loaded tankers. To prevent water and coal from spilling during transport, the water on the surface of the fully loaded tankers needs to be cleaned off.

[0003] Currently, when cleaning water from fully loaded tank trucks, coal cleaners use shovels to dig a small pit at the corner of the tank truck, allowing the water to flow into the pit. Then, they use shovels to drain the water. This method easily results in coal being discharged along with the water outside the tank truck, and it has low drainage efficiency, making it unsuitable for use. Therefore, we propose a practical tank truck water pumping device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] like Figures 1-3 As shown in the figure, a practical tanker pumping device according to one embodiment of the present invention includes a cylinder 1. The upper surface of the cylinder 1 is open. One-way water inlet valves 2 are evenly arranged circumferentially on the lower side wall of the cylinder 1. A metal filter screen 3 is threadedly installed on the lower surface of the cylinder 1, and the metal filter screen 3 covers the one-way water inlet valves 2. The upper surface of the metal filter screen 3 is open. A cleaning mechanism 4 is installed on the lower side wall of the metal filter screen 3. A sealing cap is threadedly installed on the upper surface of the cylinder 1. 5. A piston rod 6 is movably installed inside the sealing cover 5. A piston disc 7 is fixedly installed at the lower edge of the outer surface of the piston rod 6, and the outer surface of the piston disc 7 is movably fitted with the inner wall of the cylinder 1. A transmission mechanism 8 is provided on the lower side wall of the cylinder 1, and the transmission mechanism 8 is connected to the cleaning mechanism 4 and the piston rod 6. A rectangular through hole 9 is opened in the piston rod 6, and the lower surface of the rectangular through hole 9 is flush with the lower surface of the piston rod 6. A drainage mechanism 10 is installed at the upper edge of the front side of the piston rod 6.

[0017] like Figure 2 As shown, in some embodiments, the cleaning mechanism 4 includes a bearing assembly 401, a rotating shaft 402, a rectangular groove 403, a conical block 404, and a scraper 405. The bearing assembly 401 is fixedly installed on the lower side wall of the metal filter screen 3. The rotating shaft 402 is fixedly installed on the bearing assembly 401. A rectangular groove 403 is formed on the upper surface of the rotating shaft 402. A conical block 404 is fixedly installed on the lower surface of the rotating shaft 402. The upper surface edge of the conical block 404 is scraped around the circumferential edge by the scraper 405, and the inner wall of the scraper 405 is movably fitted to the outer surface of the metal filter screen 3.

[0018] In this embodiment, the bearing assembly 401 enables the rotating shaft 402 to rotate. The rotating shaft 402 rotates to the point where the conical block 404 rotates. The conical block 404 drives the scraper 405 to rotate. The scraper 405 cleans the coal that is attached to the metal filter screen 3. The conical block 404 is easy to insert into the coal. The rectangular groove 403 is easy to insert and connect to the transmission mechanism 8.

[0019] like Figure 2 and Figure 3As shown, in some embodiments, the transmission mechanism 8 includes a mechanical seal 801 and a transmission rod 802. The mechanical seal 801 is installed at the middle of the lower side wall of the cylinder 1. The transmission rod 802 is fixedly installed in the mechanical seal 801, and the upper and lower ends of the transmission rod 802 are respectively inserted into the rectangular through hole 9 and the rectangular groove 403.

[0020] In this embodiment, the mechanical seal 801 is used to install the transmission rod 802, enabling the transmission rod 802 to rotate. The transmission rod 802 can rotate with the piston rod 6 when inserted into the rectangular through hole 9, and can drive the rotating shaft 402 to rotate when inserted into the rectangular groove 403. Furthermore, the mechanical seal 801 provides a good sealing and waterproofing effect between the lower side wall of the cylinder 1 and the transmission rod 802.

[0021] like Figure 3 As shown, in some embodiments, the portion of the transmission rod 802 corresponding to the rectangular through hole 9 and the rectangular groove 403 has a rectangular cross-section when viewed from above, and the outer surface of the transmission rod 802 is in movable contact with the inner wall of the rectangular through hole 9 and the rectangular groove 403.

[0022] In this embodiment, the transmission rod 802 can rotate stably with the piston rod 6 and can stably drive the rotating shaft 402 to rotate.

[0023] like Figure 1 As shown, in some embodiments, the drainage mechanism 10 includes a drain pipe 101 and a one-way drain valve 102. The drain pipe 101 is fixedly installed on the upper edge of the front side of the piston rod 6, and the drain pipe 101 is connected to the rectangular through hole 9. The one-way drain valve 102 is installed on the drain pipe 101.

[0024] In this embodiment, the piston flows into the drain pipe 101 through the rectangular through hole 9 inside the piston rod 6 and is discharged through the drain pipe 101. The one-way drain valve 102 prevents external air from entering. A hose can be connected to the drain pipe 101 to drain the water to a suitable position.

[0025] like Figure 1 As shown, in some embodiments, a first handle 11 is fixedly installed on the left and right sides of the cylinder 1.

[0026] In this embodiment, the first handle 11 makes it easy for workers to hold the cylinder 1.

[0027] like Figure 2 As shown, in some embodiments, a second handle 12 is fixedly installed on the left and right sides of the piston rod 6, and a through hole 13 is provided on the sealing cover 5 corresponding to the piston rod 6.

[0028] In this embodiment, the second handle 12 facilitates the push and pull of the piston rod 6 by the operator, and the through hole 13 meets the requirement that the piston rod 6 can move up and down on the sealing cover 5.

[0029] In use, the cylinder 1 is inserted into the coal by holding the first handle 11, and the conical block 404 in the cleaning mechanism 4 is inserted into the coal. At this time, the piston rod 6 and the piston disc 7 are at the bottom of the cylinder 1. Then, the piston rod 6 is rotated by holding the second handle 12. The piston rod 6 drives the transmission rod 802 in the transmission mechanism 8 to rotate in the mechanical seal 801 through the rectangular through hole 9. The transmission rod 802 drives the rotating shaft 402 to rotate in the bearing assembly 401 through the rectangular groove 403. The rotating shaft 402 drives the conical block 404 to rotate, and the conical block 404 drives the scraper 405 to rotate. The scraper 405 cleans the coal adhering to the outer surface of the metal filter screen 3, creating a gap between the coal and the metal filter screen 3. At this time, the water in the coal will flow to the metal filter screen 3. The metal filter screen 3 prevents the coal from flowing to the one-way water inlet valve 2. The piston rod 6 is pulled upward by holding the second handle 12, so that the piston rod 6 drives the piston disc 7. As the piston disc 7 moves upward, it draws air from the cylinder 1. At this time, the one-way drain valve 102 on the drain pipe 101 in the drainage mechanism 10 prevents external air from entering. A negative pressure is formed inside the cylinder 1, which causes water at the one-way inlet valve 2 to be drawn into the cylinder 1. After the piston disc 7 has finished drawing water from the cylinder 1, the piston disc 7 on the piston rod 6 is pushed downward along the inner wall of the cylinder 1 by the second handle 12. At this time, the one-way inlet valve 2 prevents the water in the cylinder 1 from being discharged. The water in the cylinder 1 flows into the rectangular through hole 9 through the lower surface of the piston rod 6, and then flows into the drain pipe 101 through the rectangular through hole 9, and then is discharged through the drain pipe 101, causing the piston disc 7 to move to the bottom of the cylinder 1. This process is repeated to increase the filtration function during the drainage process, effectively prevent coal from entering, and make the metal filter screen 3 less prone to clogging. It can quickly drain the water accumulated in the cylinder 1, greatly improving the drainage efficiency and making it more convenient and efficient to use.

[0030] In summary, this practical tank truck water pumping device adds a filtration function during the pumping process, effectively preventing coal from entering. It also adds a cleaning function to the metal filter screen 3, making it easier to pump accumulated water into the cylinder 1 and quickly drain the water from the cylinder 1, greatly improving drainage efficiency and making it more convenient and efficient to use.
