Detailed Implementation
[0016] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 3As shown, the underground storage tank unloading system of this utility model includes a storage tank pre-buried underground. A delivery pipe 1 is connected to the inlet end of the storage tank. The top of the delivery pipe 1 is located within an unloading trough 2 located above ground. The bottom of the unloading trough 2 is coated with floor paint to ensure its internal cleanliness. A cover plate 3 is provided on one side of the unloading trough 2 to seal the underground cavity containing the storage tank, allowing for inspection and maintenance of the storage tank by lifting the cover plate 3. An overflow port is provided on the side wall of the delivery pipe 1 within the unloading trough 2. 4. Overflow port 4 is used to collect the spilled medicine in the unloading tank 2 into the delivery pipe 1, thereby reducing waste. Delivery pipe 1 is connected to a delivery branch pipe 5, and the bottom end of the delivery branch pipe 5 extends below the overflow port 4 to prevent the medicine from flowing back out of the overflow port 4 during normal unloading. Delivery branch pipe 5 is connected to inlet pipe 7 through a diversion pipe 6, and inlet pipe 7 is equipped with an inlet valve. During operation, inlet pipe 7 is connected to the delivery pipeline of the medicine delivery vehicle to complete the unloading operation. In addition, in this embodiment, a drug unloading pump 8 is provided at the end of the unloading tank 2 away from the drug inlet pipe 7. The drug unloading pump 8 is connected to the diversion pipe 6. This arrangement helps to meet the drug delivery port of different drug delivery vehicles, so that the drug inlet pipe 7 or the drug delivery pump can be flexibly selected for unloading according to the actual situation, thereby enhancing the practicality of this utility model. In addition, a vent valve is provided on the drug delivery branch pipe 5 to release the gas in the pipe during unloading, so as to ensure the smooth delivery of the drug liquid.
[0017] This utility model, through the setting of the unloading tank 2, can accommodate both the inlet pipe 7 and the unloading pump 8, forming a surrounding dike structure to temporarily store and collect the spilled medicine during the unloading process and the residual medicine in the pipe after unloading, avoiding environmental damage caused by spillage and improving safety. The spilled medicine enters the storage tank through the overflow port 4 via the delivery pipe 1, avoiding waste. The structure is simple and highly practical. In this embodiment, an operation port is provided on the unloading tank 2 corresponding to the inlet end of the inlet pipe 7 and the medicine pump, facilitating connection operations during unloading. A sealing plate 9 is provided on the operation port, which is sealed after unloading to ensure the cleanliness of the inside of the unloading tank 2. Preferably, an opening can also be provided at the top of the unloading tank 2, connected to the operation port, for internal maintenance. The sealing plate 9 can be used as... Figure 1 It features a multi-fold structure for easy opening and closing.
[0018] Furthermore, such as Figure 3As shown, a groove 10 is provided at the bottom of the unloading tank 2 where the drug delivery pipe 1 is located. The groove 10 is coaxially arranged with the drug delivery pipe 1, and the overflow port 4 is located inside the groove 10. This arrangement facilitates the flow of the liquid medicine to a lower position, allowing it to enter the delivery pipe through the overflow port 4. In this invention, multiple overflow ports 4 are preferably provided along the circumference of the drug delivery pipe 1 to improve overflow efficiency. In addition, a filter screen is provided inside the groove 10, covering the overflow port 4, which can filter out the contaminants in the unloading tank 2 carried by the liquid medicine, ensuring the cleanliness of the liquid medicine entering the storage tank.
[0019] Specifically, the filter screen cover includes two filter screens 11 separately disposed at the bottom, and a connecting sleeve 12 disposed at the top of each filter screen 11; the two connecting sleeves 12 are detachably connected to facilitate cleaning, maintenance and repair of the filter screens 11; the connecting sleeves 12 can be connected by screws or by setting a slider groove; in this embodiment, the two connecting sleeves 12 and the filter screens 11 are combined into a cylindrical structure, the inner diameter of which matches the outer diameter of the drug delivery tube 1, so as to tightly fit on the outside of the drug delivery tube 1 and form a filter structure outside the overflow port 4.
[0020] Furthermore, such as Figure 2 As shown, a curved dirt-collecting plate 13 with a raised edge is coaxially arranged at the bottom of the filter screen 11. The dirt-collecting plate 13 and the filter screen 11 form a dirt-collecting cavity for temporary storage of dirt. When the connecting sleeve 12 is removed later, the dirt-collecting plate 13 can be removed together for easy cleaning of dirt. When the dirt-collecting plate 13 is installed in the groove 10, the top of the dirt-collecting plate does not protrude from the groove 10, and is preferably flush with the top of the groove 10, so as to ensure that the medicine can enter smoothly into its interior while increasing the dirt-collecting area of the dirt-collecting plate 13. In addition, the dirt-collecting plate 13 is arranged from high to low from the side away from the filter screen 11 to the side closer to the filter screen 11, so that the medicine can flow smoothly along the slope to the overflow port 4, realizing the rapid discharge of the medicine. The structure is simple and highly practical.
[0021] When this utility model is in operation, the sealing plate 9 is opened to expose the inlet pipe 7 and the delivery pump. The inlet pipe 7 or the delivery pump is connected according to the matching pipe port of the medicine delivery vehicle, and the valve on the designated pipeline is opened accordingly. The spilled medicine will fall into the unloading tank 2 and enter the storage tank again through the overflow port 4. This not only avoids environmental pollution and ensures safety, but also avoids waste of medicine, making it highly practical.
[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
