Description

Technical Field

[0001] This utility model relates to the field of defoamer technology, and in particular to a defoamer injection device for oil and gas fields. Background Technology

[0002] Defoamers are functional additives used to eliminate and prevent foam formation. Their mechanism of action mainly includes two aspects: first, disrupting the existing foam structure; and second, inhibiting the formation of new foam in aqueous solutions and other media. In industrial production processes, after the defoamer completes its synthesis reaction, it is usually stored in dedicated storage tanks. When product packaging is required, the defoamer is extracted from the storage tank using a specialized dispensing device and dispensed into external containers to complete the sealing process.

[0003] The applicant obtained the following prior art through searching. Specifically, patent CN217549734U discloses a defoamer dispensing device, belonging to the technical field of defoamer dispensing. It includes a storage tank with a storage cavity and a mounting hole. A bearing is connected to the inner periphery of the mounting hole. A stirring mechanism is connected to the storage cavity. The storage tank is connected to a feeding pipe, and a discharge pipe is connected to the end of the storage tank away from the feeding pipe. An adjustment mechanism is connected to the outer periphery of the storage tank. The adjustment mechanism includes a fixed plate connected to the outer periphery of the storage tank. A motor B is connected to the end of the fixed plate away from the feeding pipe. A rotating shaft B is connected to the output end of motor B. A rotating gear is connected to the rotating shaft B. The rotating gear meshes with an incomplete gear. The incomplete gear is connected to a follower shaft, which rotatably connects to the storage tank. An adjustment plate is connected to the outer periphery of the follower shaft. The adjustment plate and the incomplete gear are symmetrically arranged. This dispensing device realizes the action of controlling the dispensing amount when dispensing defoamer, improving dispensing efficiency and dispensing according to demand.

[0004] As can be seen from the patent above, although this defoamer dispensing device achieves the action of controlling the dispensing amount during defoamer dispensing, thus improving dispensing efficiency and dispensing according to demand, in actual use, because the dispensing device's discharge pipe is located at the bottom of the storage tank, and the packaging container is located below the tank during the dispensing process, the packaging container is quite heavy after being filled with defoamer. At this time, it is difficult for workers to quickly move it away and replace the unfilled packaging container, which is not only time-consuming and labor-intensive, increasing the labor intensity of workers, but also reduces dispensing efficiency.

[0006] To achieve the above objectives, this utility model provides an antifoaming agent dispensing device for oil and gas fields, comprising a tank body and a tank cover. The tank cover is provided with a feed pipe and includes a fixed base, a movable base, a drive mechanism, a stirring mechanism, and a cleaning mechanism.

[0008] Preferably, a positioning part is formed on the movable seat corresponding to the position of the discharge pipe.

[0009] Preferably, the movable seat has a groove for placing an external container, and through slots are formed on the opposite sides of the groove along the moving direction of the movable seat. A baffle for abutting against the external container is provided in the groove, and the two ends of the baffle are detachably connected to the through slots by locking members.

[0010] Preferably, the stirring mechanism includes a second driving member, a rotating shaft, and a plurality of stirring blades. The second driving member is disposed on the tank cover, and the power output end of the second driving member is detachably connected to the rotating shaft.

[0011] Preferably, the stirring mechanism further includes a scraper, the two ends of which are detachably mounted on the rotating shaft via connecting rods, and the scraper is used to scrape the inner wall of the tank.

[0012] Preferably, the cleaning mechanism includes a water inlet pipe, an infusion pipe, and several nozzles. The water inlet pipe is disposed on the tank cover and is used to connect to an external water supply system. The infusion pipe is arranged in a ring shape inside the tank and is detachably connected to the water inlet pipe. Several nozzles are evenly and spaced along the extension direction of the infusion pipe.

[0013] Preferably, a plurality of rollers are arranged in a rectangular array on the bottom surface of the fixed base; a push rod is provided on the top surface of the fixed base.

[0014] Beneficial effects: 1. In the defoamer filling device for oil and gas fields of this utility model, the external container can be moved by the driving mechanism, so that the workers can quickly move the external container full of defoamer away, and thus conveniently replace the unfilled external container. It is not only simple to operate, time-saving and labor-saving, reducing the labor intensity of the workers, but also improving the filling efficiency.

[0015] 2. In the defoamer dispensing device for oil and gas fields of this utility model, the stirring mechanism can not only prevent the defoamer from stratifying or settling when it is stored in the tank, ensuring that the composition of each batch of product is consistent, but also break the foam clusters formed in the tank during the dispensing process, thereby effectively avoiding the foam from affecting the flow stability of the discharge pipe.

[0016] 3. In the defoamer filling device for oil and gas fields of this utility model, since a cleaning mechanism is provided on the tank cover, the cleaning mechanism can wash the stirring mechanism and the inner wall of the tank by spraying or high-pressure water flow, thereby effectively removing residual defoamer and deposits.

[0017] 4. In the defoamer filling device for oil and gas fields of this utility model, the fixed seat can isolate the external container from the external environment during the filling process of the defoamer, thereby preventing external dust, impurities, etc. from entering the external container and contaminating the defoamer, ensuring the quality of the defoamer and its reliable use.

[0027] Example 1: This utility model proposes a defoamer injection device for oil and gas fields.

[0028] In one embodiment of this utility model, an oil and gas field defoamer dispensing device includes a tank body 1 and a tank cover 2. The tank cover 2 is provided with a feed pipe and includes a fixed base 3, a movable base 4, a drive mechanism, a stirring mechanism, and a cleaning mechanism. The tank body 1 is disposed on the top of the fixed base 3, and the bottom of the tank body 1 is provided with a discharge pipe 5 passing through the fixed base 3. The movable base 4 is movably installed on the bottom of the fixed base 3 by the drive mechanism and is used to place an external container 100. An opening 6 is formed on one side of the fixed base 3 for the movable base 4 to pass through. The stirring mechanism is disposed in the tank body 1 and is used to stir the defoamer. The cleaning mechanism is disposed on the tank cover 2 and is used to rinse the stirring mechanism and the tank body 1.

[0029] Specifically, such as Figures 1 to 5As shown, in this utility model of an oil and gas field defoamer filling device, the tank 1 can temporarily store the defoamer, and the tank cover 2 can be detachably connected by bolts, buckles, or other means, thereby sealing the tank 1 to prevent the defoamer inside the tank 1 from being contaminated by external impurities. The structural design is simple and reasonable. Furthermore, since the tank 1 is located on top of the fixed base 3, and the bottom of the tank 1 has a discharge pipe 5 passing through the fixed base 3, the defoamer inside the tank 1 can naturally flow into the fixed base 3 from the discharge pipe 5. Simultaneously, since the bottom of the fixed base 3 is movably mounted with a movable seat 4 for placing an external container 100 via a drive mechanism, and one side of the fixed base 3 has an opening 6 for the movable seat 4 to pass through, when defoamer needs to be added, the movable seat 4 can extend from the opening 6 to the outside of the fixed base 3 under the action of the drive mechanism. At this time, the operator... The outer container 100 can be placed on the movable seat 4. After the outer container 100 is in place, the drive mechanism drives the movable seat 4 to retract back into the fixed seat 3 through the opening 6, and moves the outer container 100 to below the discharge pipe 5. This allows for the addition of defoamer, which is simple to operate. Furthermore, when the outer container 100 is full of defoamer, the drive mechanism can extend the movable seat 4 and the outer container 100 filled with defoamer from the opening 6, making it easy for workers to quickly move and replace the unfilled outer container 100. This makes it convenient to use.

[0030] It should be noted that a solenoid valve is installed at the discharge pipe 5, which can open and close the discharge pipe 5 to achieve quantitative filling of the external container 100. Furthermore, a control system is installed on the fixed base 3. The control system is communicatively connected to the drive mechanism, stirring mechanism, and cleaning mechanism to drive each mechanism to operate or stop. The solenoid valve and control system are mature and conventional existing technologies, and will not be described in detail here. Their specific structures are not shown in the accompanying drawings. The main purpose of this utility model, an oil and gas field defoamer filling device, is to solve the problem that existing defoamer filling devices are difficult to move quickly and replace unfilled external containers 100, which is time-consuming, labor-intensive, increases the workload of workers, and reduces filling efficiency.

[0031] Understandably, since the tank 1 is equipped with a stirring mechanism, the stirring mechanism can prevent the defoamer from stratifying or settling when stored in the tank 1 (especially for some oil and gas field defoamers containing solid particles or high viscosity components on the market), ensuring that the composition of each batch of product added is consistent. At the same time, during the addition of the defoamer, the mechanical stirring action of the stirring mechanism can break up the foam clumps formed in the tank 1, thereby effectively preventing foam from affecting the flow stability of the discharge pipe 5. In addition, since the tank cover 2 is equipped with a cleaning mechanism, the cleaning mechanism can rinse the stirring mechanism and the inner wall of the tank 1 through spraying or high-pressure water flow, thereby effectively removing residual defoamer and deposits. This not only avoids cross-contamination between different batches of products, but also ensures the cleanliness and hygiene of the inside of the tank 1, improves the maintenance efficiency of the equipment, and extends its service life.

[0032] Compared with existing technologies, in this utility model of an oil and gas field defoamer dispensing device, the driving mechanism can move the external container 100, allowing workers to quickly move the external container 100 filled with defoamer and conveniently replace the unfilled external container 100. This not only simplifies operation, saves time and labor, reduces the workload of workers, but also improves dispensing efficiency. The stirring mechanism not only prevents the defoamer from stratifying or settling during static storage in the tank 1, ensuring consistent composition for each batch of product, but also breaks up foam clumps formed in the tank 1 during the dispensing process. Effectively prevents foam from affecting the flow stability of the discharge pipe 5; since the tank cover 2 is equipped with a cleaning mechanism, the cleaning mechanism can rinse the stirring mechanism and the inner wall of the tank 1 through spraying or high-pressure water flow, thereby effectively removing residual defoamer and deposits, which can not only avoid cross-contamination between different batches of products, but also ensure the cleanliness and hygiene of the inside of the tank 1, improve the maintenance efficiency of the equipment and extend its service life; in addition, the fixing seat 3 can isolate the external container 100 from the external environment during the defoamer filling process, thereby preventing external dust, impurities, etc. from entering the external container 100 and contaminating the defoamer, ensuring the quality of the defoamer and reliable use.

[0033] In one embodiment, mounting grooves 7 are respectively formed on opposite sides of the bottom of the fixed base 3, and hanging portions 8 are respectively formed on both sides of the movable base 4. Each hanging portion 8 has a limiting groove for the groove wall of the mounting groove 7 to extend into. The driving mechanism includes two first driving members 9, which are respectively disposed in the two mounting grooves 7 and are drively connected to the movable base 4. Specifically, as shown... Figure 1 and Figure 2As shown, mounting grooves 7 are respectively provided on both sides of the bottom of the fixed seat 3, and mounting parts 8 with limit grooves are provided on both sides of the movable seat 4. This allows the groove wall of the mounting groove 7 to be embedded into the limit groove to form a double guiding constraint, thereby effectively preventing the movable seat 4 from tilting or getting stuck during movement and ensuring translational stability. Furthermore, the first driving component 9 can be a linear reciprocating device such as a cylinder, hydraulic cylinder, or electric push rod 22 in the prior art. This allows the movable seat 4 to move smoothly relative to the fixed seat 3 under the action of the first driving component 9. At the same time, by setting the two first driving components 9 in the two mounting grooves 7 respectively, the symmetrical distribution of driving force can be achieved. This avoids the torque imbalance problem caused by single-point drive and improves the movement stability of the movable seat 4 when carrying an external container 100 filled with defoamer through dual-drive synchronous control. The structural design layout is simple and reasonable.

[0034] In one embodiment, a positioning part 10 is formed on the movable seat 4 corresponding to the position of the discharge pipe 5. Specifically, as shown in the figure... Figures 1 to 4 As shown, the positioning part 10 enables precise alignment between the outer container 100 and the discharge pipe 5, effectively preventing the defoamer from splashing out of the outer container 100 during the filling process, thus avoiding waste and pollution. It should be noted that the outer container 100 commonly used for filling defoamer in the prior art typically has an arched bottom, thus often forming an arc-shaped groove on its bottom surface. The precise alignment of the outer container 100 can be achieved through the insertion and engagement of the positioning part 10 with this arc-shaped groove, demonstrating a clever and reasonable structural design. Furthermore, for outer containers 100 with a flat bottom, the positioning part 10 can be provided with a through hole aligned with the discharge pipe 5, facilitating the placement of the outer container 100 by operators, making operation simple and convenient.

[0035] In one embodiment, the movable seat 4 has a groove 11 for placing an external container 100. On the opposite sides of the groove 11, through grooves 12 are provided along the moving direction of the movable seat 4. A baffle 13 for abutting against the external container 100 is provided in the groove 11. The two ends of the baffle 13 are detachably connected to the through groove 12 by locking members.

[0036] Specifically, such as Figures 1 to 4As shown, by opening a groove 11 on the movable seat 4, the distance between the movable seat 4 (top surface) and the discharge pipe 5 can be increased, allowing the operator to place external containers 100 of different heights on the movable seat 4, thus improving the flexibility and applicability of use. At the same time, since through slots 12 are opened on the opposite sides of the groove 11 along the moving direction of the movable seat 4, and baffles 13 are provided in the groove 11, the two ends of the baffles 13 are detachably connected to the through slots 12 by locking parts. The locking parts can be bolts in the prior art, which have the characteristics of easy material availability, compact structure and convenient disassembly and assembly. Thus, the operator can flexibly adjust the installation position of the baffles 13 on the movable seat 4 according to the actual size (width or diameter) of the external container 100, so as to ensure that the baffles 13 always abuts against the outer wall of the external container 100, thereby providing limiting support for the external container 100 in the moving direction, effectively preventing the external container 100 from tipping over and causing waste of defoamer or pollution of the working environment, and ensuring reliable use.

[0037] In one embodiment, the stirring mechanism includes a second driving member 14, a rotating shaft 15, and a plurality of stirring blades 16. The second driving member 14 is disposed on the tank cover 2, and the power output end of the second driving member 14 is detachably connected to the rotating shaft 15. The rotating shaft 15 is vertically inserted into the tank body 1, and a plurality of stirring blades 16 are evenly and spaced along its extension direction on the rotating shaft 15. Specifically, as shown... Figure 1 and Figure 5 As shown, the second drive component 14 can be a motor as in the prior art. The second drive component 14 can be installed on the tank cover 2 by means of a threaded connection, which facilitates the disassembly and assembly of the second drive component 14 by the staff and is conducive to maintenance. At the same time, since the power output end of the second drive component 14 is detachably connected to the rotating shaft 15, the rotating shaft 15 is vertically inserted into the tank body 1, and a number of stirring blades 16 are evenly and spaced along its extension direction on the rotating shaft 15. Thus, the stirring blades 16 can play a three-dimensional and all-round stirring and mixing role for the defoamer in the tank body 1, which not only eliminates the dead corners of stirring, but also ensures the full fusion of the upper and lower layers of defoamer in the tank body 1, so that the defoamer always maintains good fluidity and stability, providing quality assurance for subsequent filling operations.

[0038] In one embodiment, the stirring mechanism further includes a scraper 17, the two ends of which are detachably mounted on the rotating shaft 15 via connecting rods. The scraper 17 is used to scrape the inner wall of the tank 1. Specifically, as shown... Figure 1 and Figure 5As shown, the scraper 17 is connected to the rotating shaft 15 via a connecting rod. When the second driving member 14 drives the rotating shaft 15 to rotate, the scraper 17 can closely adhere to the inner wall of the tank 1 and remove the defoamer adhering to the inner wall of the tank 1, thereby effectively avoiding waste of defoamer and ensuring reliable use. At the same time, the scraper 17 can be used in conjunction with the cleaning mechanism to scrape off the residual sediment on the inner wall of the tank 1, thereby maintaining the cleanliness of the inner wall of the tank 1 and ensuring the purity of the defoamer each time it is added.

[0039] In one embodiment, such as Figure 1 and Figure 5 As shown, the cleaning mechanism includes a water inlet pipe 18, a liquid delivery pipe 19, and several nozzles 20. The water inlet pipe 18 is mounted on the tank cover 2 and is used to connect to an external water supply system. The liquid delivery pipe 19 is arranged in a ring shape inside the tank body 1 and is detachably connected to the water inlet pipe 18. Several nozzles 20 are evenly and spaced along the extension direction of the pipe wall of the liquid delivery pipe 19. Specifically, the ring-shaped liquid delivery pipe 19 and several nozzles 20 ensure that the cleaning liquid input from the external water supply system completely covers all areas inside the tank body 1, including key parts such as several stirring blades 16, scrapers 17, and the tank wall. This not only ensures the cleaning effect inside the tank body 1 but also significantly shortens the cleaning time and improves the overall work efficiency.

[0040] In one embodiment, a plurality of rollers 21 are arranged in a rectangular array on the bottom surface of the fixing base 3; a push rod 22 is provided on the top surface of the fixing base 3. Specifically, as shown... Figures 1 to 4 As shown, the rollers 21 can be casters, which are common in the prior art. This facilitates the handling and flexible adjustment of the placement of the defoamer dispensing device for oil and gas fields, allowing for flexible layout of the workshop environment. In addition, the push rod 22 provided on the top surface of the fixed base 3 makes it easy for workers to push the defoamer dispensing device for oil and gas fields, making it simple to operate and convenient to use.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
