Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of petroleum chemical industry, in particular to a medicament filling device, a medicament filling system and a method. BACKGROUND

[0002] The formation water low-temperature distillation treatment workshop evaporates formation water by steam. Due to the complex composition of formation water, boiling phenomenon occurs in the evaporation process, and boiling phenomenon is also the most common abnormal phenomenon in the formation water treatment process. The boiling phenomenon causes the formation water to overflow the treatment device, pollutes other treated condensed water, and therefore, a defoaming agent needs to be filled in time in the device where the boiling phenomenon occurs. The conventional filling method is to fill the defoaming agent into a temporary medicament storage device through a funnel, and the air in the temporary medicament storage device replaced by the defoaming agent also needs to be discharged upward through the funnel. At this time, due to the reverse flow of air and defoaming agent in the same channel, the downward flow of the defoaming agent is hindered, causing slow filling speed, and the worker needs to spend a long time to complete the medicament filling process once. If the boiling reaction is rapid or the boiling phenomenon occurs in multiple devices at the same time, it is easy to cause liquid channeling due to the delay of filling, thereby causing the boiling phenomenon to intensify. In addition, air flows out of the temporary medicament storage device during the filling process, causing the medicament in the funnel to bubble and fly. SUMMARY

[0003] The present application provides a medicament filling device for filling medicament into a formation water treatment device, which effectively avoids the problem of medicament splashing caused by air bubbles during the filling process.

[0016] The application also provides a method for filling medicament into a formation water treatment device by using the medicament filling system as described above, which comprises the following steps:

[0017] Step 1: filling the medicament storage device with water;

[0018] Step 2: opening the first valve, pouring an appropriate amount of medicament into the medicament filling device, and reading the liquid level of the medicament when the medicament in the medicament filling device is stable and no bubbles are generated;

[0019] Step 3: open the vent valve, water in the medicine storage device flows out from the vent valve, at the same time, the medicine in the medicine filling device enters the medicine storage device, when the amount of medicine entering the medicine storage device reaches the required amount, close the vent valve and the first valve;

[0029] The invention will now be further described with reference to the accompanying drawings.

[0030] like Figure 1 As shown, the present invention provides a pharmaceutical dispensing device mainly composed of a first container 3, a second container 2, a connecting pipe 9, and an intercepting net 1. The first container 3 is used to load pharmaceuticals, and an inlet is provided at the top of the first container 3, through which pharmaceuticals can be added. A cover can be provided on the inlet to prevent dust and foreign objects from entering the interior of the first container 3. The second container 2 is located inside the first container 3. The top of the second container 2 has an opening, and several first through holes 6 are formed on its lower side wall, penetrating the side wall of the second container 2, thus connecting the interior of the second container 2 with the interior of the first container 3. The connecting pipe 9 has upper and lower ends. The lower end of the connecting pipe 9 is located outside the first container 3, and the upper end of the connecting pipe 9 penetrates the bottom surface of the first container 3 and the bottom surface of the second container 2 before extending into the space inside the second container 2. A second through hole 7 is formed on the pipe wall of the section of the connecting pipe 9 located between the bottom surface of the first container 3 and the outer wall of the second container 2, through which the connecting pipe 9 and the first container 3 are connected. The interception net 1 is installed inside the second container 2. The interception net 1 is located above the first through hole 6 and the upper end of the connecting pipe 9. The edge of the interception net 1 is tightly connected to the inner wall of the second container 2 to prevent bubbles from rising directly along the inner wall of the second container 2 without passing through the interception net 1.

[0031] When the bubbles from the upper end of the connecting pipe 9 enter the second container 2, they are guided by the second container 2 to rise to the intercepting net 1, and are intercepted and divided by the intercepting net 1, so as to weaken the rising force of the bubbles, thereby effectively avoiding the problem of splashing of the medicament caused by the bubbles during the filling process. In addition, the medicament brought back by the bubbles can flow into the first container 3 through the first through hole 6 on the side wall of the second container 2 to continue filling, and the medicament in the first container 3 flows into the connecting pipe 9 from the second through hole 7 on the connecting pipe 9 under the action of gravity, and the medicament is filled outwards through the connecting pipe 9.

[0032] In order to facilitate obtaining the liquid level of the medicament in the first container 3, in some embodiments, the first container 3 can be made of transparent material as a whole, and a scale line is arranged on the first container 3 to indicate the liquid level in the first container 3. In other embodiments, a transparent window can be arranged on the first container 3, and a scale line for indicating the liquid level in the first container 3 is arranged on the transparent window or the edge of the transparent window, and the liquid level in the first container 3 can be obtained through the transparent window and the scale line. In still other embodiments, a liquid level gauge can be arranged on the first container 3 to detect the liquid level in the first container 3.

[0033] In order to prevent the bubbles from escaping from the second through hole 7 on the connecting pipe 9 into the first container 3 during the rising process to cause the medicament to splash, an anti-escape cover 4 can be arranged in the first container 3, the anti-escape cover 4 is sleeved on the outer wall of the connecting pipe 9 below the second container 2 and covers the second through hole 7, the side wall and the top surface of the anti-escape cover 4 and the outer wall of the connecting pipe 9 form a cavity with a closed top, and the bubbles escaping from the second through hole 7 enter the anti-escape cover 4, rise to the cavity under the guidance of the anti-escape cover 4 and stay in the cavity. The lower part of the anti-escape cover 4 is in communication with the first container 3, so that the medicament in the first container 3 can enter the anti-escape cover 4 and then enter the inside of the connecting pipe 9 through the second through hole 7.

[0034] In order to make the inside of the anti-escape cover 4 communicate with the first container 3, as shown in Figure 1 some embodiments, a plurality of third through holes 8 can be formed in the side wall of the anti-escape cover 4 below the second through hole 7, the anti-escape cover 4 and the first container 3 communicate through the third through holes 8, and the medicament in the first container 3 can enter the anti-escape cover 4 through the third through holes 8. In this scheme, the anti-escape cover 4 can be fixedly installed on the outer wall of the connecting pipe 9 and supported by the connecting pipe 9, or the bottom of the anti-escape cover 4 can be fixedly installed on the bottom surface of the first container 3 and supported by the bottom surface of the first container 3.

[0035] In other embodiments, the anti-channeling cover 4 may not have a separate through hole. Instead, the anti-channeling cover 4 is suspended and fixedly installed on the outer wall of the connecting pipe 9 and supported by the connecting pipe 9. At the same time, it is ensured that there is a gap between the bottom of the anti-channeling cover 4 and the bottom surface of the first container 3. The inside of the anti-channeling cover 4 and the inside of the first container 3 are connected through this gap, and the medicine in the first container 3 can enter the anti-channeling cover 4 through the gap.

[0036] During formation water treatment, the steam temperature inside the container reaches approximately 150°C, while the liquid temperature is around 120°C. Due to the high internal temperature of the container, if the valve opening and closing sequence of the dosing system is incorrect or internal leakage occurs during the dosing operation, not only will steam and liquid leak out together, but it may also cause burns to the operators. To prevent steam and liquid from backflowing from the connecting pipe 9 during dosing, causing contamination and burns, in some embodiments, a one-way valve 5 is installed on the connecting pipe 9 located below the first container 3. The input end of the one-way valve 5 is connected to the first container 3, and the output end of the one-way valve 5 is connected to the lower end of the connecting pipe 9. The one-way valve 5 allows the chemicals in the connecting pipe 9 to flow downwards through the connecting pipe 9, while preventing steam and liquid from backflowing upwards through the one-way valve 5. Since the upward force of the bubbles is insufficient to close the one-way valve, the one-way valve 5 does not prevent the bubbles from rising and entering the dosing device.

[0037] The reagent dispensing device provided by this invention can be applied to a reagent dispensing system for dispensing reagents into a formation water treatment device 400. For example... Figure 2 As shown, the drug dispensing system mainly includes a drug dispensing device 100 and a drug storage device 500 for temporary drug storage. The drug dispensing device 100 is located above the drug storage device 500. The lower end of the connecting pipe 9 of the drug dispensing device 100 is connected to the top of the drug storage device 500 via a pipe. A first valve 200 is installed on this pipe to control the opening and closing of the connecting pipe between the drug dispensing device 100 and the drug storage device 500, thereby controlling the dispensing of the drug into the drug storage device 500. A water inlet pipe 800 is also installed at the top of the drug storage device 500, which is connected to pressurized water. A second valve 300 is installed on the water inlet pipe 800 to control the opening and closing of the water inlet pipe 800, thereby controlling the entry of pressurized water into the drug storage device 500. The storage device 500 has a liquid outlet pipe 900 at its bottom, which connects to the formation water treatment device 400. A third valve 600 is installed on the liquid outlet pipe 900 to control the opening and closing of the pipe, thereby controlling the addition of chemicals from the storage device 500 to the formation water treatment device 400. The storage device 500 also has a vent pipe 1000 at its bottom, with a vent valve 700 installed on it. The vent valve 700 controls the opening and closing of the vent pipe 1000, thereby controlling the discharge of liquid from the storage device 500.

[0038] The medicament filling system can be used to fill the formation water treatment device 400 with medicament, which is a defoaming agent with a density less than water, which will float on the water surface after being added to the water. The pressurized water can be pressurized condensed water, and the filling method includes the following steps:

[0039] Step 1: Ensure that the medicament storage device 500 is filled with water; if there is no water in the medicament storage device 500, ensure that the first valve 200 and the third valve 600 are closed, then open the vent valve 700 and the second valve 300, and introduce pressurized condensed water into the medicament storage device 500, and flush the medicament storage device 500 with the condensed water to remove the air inside, then close the vent valve 700 and the second valve 300 in turn;

[0040] Step 2: Open the first valve 200, pour an appropriate amount of medicament into the medicament filling device 100, and read the medicament level when the medicament in the medicament filling device 100 is stable and no bubbles are emitted;

[0041] Step 3: Open the vent valve 700, the water in the medicament storage device 500 flows out from the vent valve 700, under the action of atmospheric pressure, the medicament in the medicament filling device 100 enters the medicament storage device 500, and the medicament level in the medicament filling device 100 is observed, when the amount of medicament entering the medicament storage device 500 reaches the required amount, the vent valve 700 is closed, and the first valve 200 is closed;

[0042] Step 4: Open the second valve 300 and the third valve 600, and use pressurized condensed water to push the medicament in the medicament storage device 500 into the formation water treatment device 400 to achieve the purpose of rapid filling;

[0043] Step 5: When the medicament in the medicament storage device 500 is completely injected into the formation water treatment device 400, close the second valve 300 and the third valve 600, and complete the medicament filling.
