Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical dispensing technology, specifically relating to a modular and mobile pharmaceutical dispensing device. Background Technology

[0002] In the later stages of gas well production, as the formation energy gradually decreases and the bottom hole pressure drops, the well's water-carrying capacity weakens, leading to severe water accumulation at the bottom of the well. This increases the resistance to natural gas flow, ultimately causing a decline in gas production. If the formation water cannot be removed in time, it will severely impact the well's productivity. To remove the accumulated fluid at the bottom of the well and improve production, it is usually necessary to inject chemicals into the well to force the fluid to flow out with the gas flow, thus purifying the fluid at the bottom of the well.

[0003] During practical operation, the applicant found that: First, on-site drainage generally uses fixed solid injection devices. This method involves high investment costs, is fixed and occupies a large area, cannot be easily dismantled or moved, and the devices are mostly idle and cannot be reused. Having one injection device per station leads to high investment costs and significant resource waste. Second, the solid injection method has stringent practical conditions; it requires a certain amount of liquid in the wellbore for injection and is prone to clogging the gas well's gas flow channels, affecting gas well production. Third, fixed injection devices are not ergonomically designed, posing safety risks such as increased labor intensity for employees, increased safety risks during operation, or injury from falling objects during operation. Utility Model Content

[0004] In view of this, the present invention provides a modular and mobile chemical dispensing device to solve the problem that chemical dispensing devices are not currently installed at mining sites, but are needed to assist production.

[0005] The technical solution is as follows:

[0006] A modular, portable drug dispensing device, the key feature of which is that it includes:

[0007] The hydraulic lifting base has an upper support frame;

[0008] The handcart is slidably supported on the upper support frame;

[0009] The mounting base is detachably fixed to the trolley and is equipped with a filling pump and piping assembly.

[0010] The above solution allows for modular assembly of each component, and the hydraulic lifting base and handcart facilitate loading and unloading of the entire unit, greatly improving mobility and transportation convenience. This helps meet the refueling needs of more sites. When gas wells or other process equipment do not require refueling, the modules can be disassembled, loaded onto a vehicle, and transported to other production sites for reuse. This effectively improves work efficiency and resource reusability, making it highly practical and economical. Compared to other skid-mounted equipment fixed to vehicles, loading and unloading is more flexible, convenient, and offers greater choice.

[0011] Preferably, the hydraulic lifting base is an electro-hydraulic lifting base, with a control box located at one end of the upper support frame. This design offers greater ease of operation and improves user-friendliness.

[0012] Preferably, the trolley and the upper support frame are slidably connected by a pull-out slide rail;

[0013] The handcart is equipped with casters on both sides of its bottom, and the height of the casters is greater than the thickness of the hydraulic lifting base when it is folded up. With this design, when the hydraulic lifting base is folded up, the casters are actually in contact with the support surface, allowing the entire cart to be moved to the destination position with the help of the casters, which is relatively more convenient and less strenuous.

[0014] Preferably, the piping assembly includes a pump outlet hose, a filling hose, and a return hose;

[0015] The outlet end of the pump outlet hose is connected to a five-way pipe, and the main outlet end of the five-way pipe is connected in sequence to a one-way valve and a high-pressure shut-off relief valve. The two outlet ends of the high-pressure shut-off relief valve are respectively connected to the filling hose and the return hose.

[0016] Preferably, two bypass ports of the five-way pipe are connected to a pressure gauge and a high-pressure shut-off valve, respectively. A three-way connector A connects the high-pressure shut-off valve to the return hose, and the high-pressure shut-off valve is connected to one of the ports of the three-way connector A. This two-stage shut-off valve structure effectively improves the safety factor of high-pressure refueling.

[0017] Preferably, a safety valve is connected to one bypass port of the five-way pipe, and the overflow port of the safety valve is connected to the return hose. Using this scheme, the safety valve, in conjunction with a two-stage shut-off valve, further improves the safety factor. When the pressure exceeds the design value, the pressure can be directly returned through the overflow port of the safety valve, effectively ensuring safety during operation. Compared to fixed-type dosing rod operation, safety risks are reduced and controlled.

[0018] Preferably, both ends of the pump outlet hose, filling hose, and return hose are quick-connect couplings. This design significantly improves ease of assembly and disassembly, facilitates the replacement of individual components, extends the overall service life of the equipment, and allows for quick replacement of different reagent tanks according to varying on-site reagent requirements, thus improving work efficiency.

[0019] Preferably, a filter is connected to the inlet end of the filling pump. Using this method, large particulate impurities can be filtered out.

[0020] Preferably, the filling pump is equipped with an inverter. Using the above solution, since most on-site power supplies are 220V, the inverter can quickly convert the 220V power supply to 380V to power the pump.

[0021] Preferably, the mounting base is equipped with an overhead plate, on which all metal pipe fittings in the piping assembly are mounted. This design improves the utilization efficiency of vertical space and facilitates the fixing of wiring or flexible conduits.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The modular and mobile reagent dispensing device provided by this utility model addresses several issues from the perspectives of modularity and mobility. Firstly, the modular assembly and detachable connection method facilitates rapid component replacement and extends the overall service life. Secondly, the mobile dispensing device caters to the needs of other gas wells, improving work efficiency and resource reuse, while maintaining low overall implementation costs and facilitating widespread application. Thirdly, the device significantly reduces the labor intensity of operators and improves work efficiency. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] refer to Figures 1 to 7 This application discloses a modular, mobile pharmaceutical dispensing device, which mainly includes a hydraulic lifting base 100, a handcart 200, and a mounting base 300. In addition, it usually includes a pharmaceutical tank 800 for use in conjunction with the device. The hydraulic lifting base 100 has a lifting function and is a common forklift lifting structure with an upper support frame 110 and a lower support frame 130. The handcart 200 is slidably supported on the upper support frame 110. The mounting base 300 is detachably fixed to the handcart 200 and is mainly used to install the dispensing pump 400 and the pipeline assembly 500. The pharmaceutical tank 800 is mainly used to hold a mixture of water or pharmaceuticals.

[0033] In specific implementation, the hydraulic lifting base 100 is an electro-hydraulic lifting base, and is equipped with a mobile power supply, as shown in the figure. The electro-hydraulic lifting base also includes a scissor telescopic structure connecting the upper support frame 110 and the lower support frame 130. The scissor telescopic structure has an integrated electric control cylinder. At the same time, one end of the upper support frame 110 is equipped with a control box 120, which is used to control the operation of the cylinder to realize the extension and retraction of the scissor telescopic structure.

[0034] In this application, the trolley 200 and the upper support frame 110 are slidably connected by a pull-out slide rail 600. The trolley 200 has a foldable handle 220. The bottom of the load plate of the trolley is provided with casters 210 on both sides, and the height of the casters 210 is greater than the thickness of the hydraulic lifting base 100 when it is folded up. When the hydraulic lifting base 100 is in the retracted state, the casters 210 are in contact with the support surface and bear the weight. This allows for more convenient short-distance movement of the entire device. When long-distance transport of the entire device is required, the device can be moved to the back of a transport truck bed (pickup truck or van), and the hydraulic lifting base 100 can be raised until the casters 210 of the handcart 200 are basically level with or slightly higher than the truck bed. Then, the handcart 200 can be pushed horizontally into the truck bed. Once all the casters 210 of the handcart 200 are in the truck bed, the hydraulic lifting base 100 can be retracted. Since the upper support frame 110 is relatively fixed, the lower support frame 130 retracts upwards. After retraction, the entire device is pushed under the handcart 200, thus completing the loading of the entire device. The unloading process is the reverse of the above.

[0035] In this embodiment, in order to save height space, the pull-out slide rails 600 are set on both sides of the upper support frame 110. At the same time, for ease of operation, the upper support frame 110 is slightly longer than the lower support frame 130, so as to reduce interference during the loading and unloading process.

[0036] The pipeline assembly 500 in this application mainly includes a pump outlet hose 510, a filling hose 520, and a return hose 530, wherein the pump outlet hose 510 and the filling hose 520 are both high-pressure hoses.

[0037] The inlet end of the pump outlet hose 510 is connected to the outlet of the filling pump 400. The outlet end is connected to a five-way pipe 540. The main outlet end of the five-way pipe 540 is connected in sequence to a one-way valve 550 and a high-pressure shut-off relief valve 560. The high-pressure shut-off relief valve 560 is a high-pressure shut-off valve with a venting function. Its two outlet ends are connected to the filling hose 520 and the return hose 530, respectively.

[0038] In specific implementation, two bypass ports of the five-way pipe 540 are respectively connected to a pressure gauge 541 and a high-pressure shut-off valve 542. A tee connector A570 is connected between the high-pressure shut-off relief valve 560 and the return hose 530. The high-pressure shut-off valve 542 is connected to one port of the tee connector A570. One bypass port of the five-way pipe 540 is connected to a safety valve 543. The overflow port of the safety valve 543 is connected to the return hose 530. Specifically, a tee connector B580 is provided between the tee connector A570 and the return hose 530. The overflow port of the safety valve 543 is connected to the bypass port of the tee connector B580 through the overflow hose 544 (e.g., Figure 5 As shown), this reduces the length of the external hose. In addition, the overflow hose 544 can also be extended to connect directly to the reagent tank 800 (as shown). Figure 4 (As shown).

[0039] In this embodiment, to further improve the safety of the pipeline assembly 500, a ball valve 590 is provided between the five-way pipe 540 and the pump outlet hose 510.

[0040] In addition, to improve space utilization, an overhead plate 310 is provided on the mounting base 300 in this embodiment. All metal pipes in the pipeline assembly 500 are detachably installed on the overhead plate 310. Some hoses can pass under the overhead plate 310. In addition, the metal pipes in the pipeline assembly 500 are generally distributed in a "U" shape, so that the pumping hose 510 and the return hose 530 are basically on the same side, which can better connect to the medicine tank 800 and avoid pipeline tangling. At the same time, it can also prevent the metal pipes from exceeding the range of the overhead plate 310, and can also better realize modular assembly and disassembly.

[0041] The top of the medicine tank 800 is provided with a reflux port and the bottom is provided with a liquid outlet. The inlet end of the filling pump 400 is connected to a liquid inlet hose, which is connected to the liquid outlet of the medicine tank 800 and is connected by a quick connector. In addition, both ends of the pump outlet hose 510, the filling hose 520 and the reflux hose 530 are quick connectors.

[0042] In practical implementation, a filter 700 is typically connected to the inlet end of the filling pump 400, as shown in the figure. The filter 700 is located between the filling pump 400 and the reagent tank 800. It can be placed independently or fixed to a handcart during use. Furthermore, to better adapt to on-site power supply, the filling pump 400 is equipped with an inverter in this application.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
