Description

Technical Field

[0001] This utility model relates to the field of chemical reagent storage technology, and in particular to a device for holding bactericides used in oil and gas well fracturing. Background Technology

[0002] Bactericides, also known as biocides, bactericides and algaecides, are chemical agents that can effectively control or kill bacteria, fungi and algae in water systems.

[0003] In the process of oil extraction, fracturing equipment is required. The fracturing process involves using a fracturing truck to deliver high-pressure, high-volume fracturing fluid to the oil layer through a high-pressure pipe. The waste liquid after the fracturing process is completed contains a large amount of particulate matter, petroleum products, and various other additives, so it is necessary to use bactericides to treat it.

[0004] During storage, bactericides are usually stored directly in tanks or barrels. However, current storage devices can only store solutions of a single concentration, making it inconvenient to store multiple liquids. When using these solutions, workers need to carry multiple solutions of different concentrations, which undoubtedly increases their workload. Furthermore, carrying multiple tanks or barrels of solutions is very inconvenient. Therefore, this application proposes a bactericide storage device for oil and gas well fracturing, which can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for holding bactericides for fracturing oil and gas wells.

[0006] The purpose of this utility model is achieved through the following technical solution: a bactericide container for fracturing oil and gas wells, comprising an outer cylinder with an opening at the top, an inner cylinder that can move up and down reciprocally installed inside the outer cylinder, with an insulation layer filling between the two, and multiple storage cavities arranged in an upper and lower array inside the inner cylinder, with space left between the multiple storage cavities, and each of the multiple storage cavities is filled with a buffer pad and two moisture-proof pads, with mounting holes opened on one side of each of the multiple storage cavities, valves installed inside the multiple mounting holes, and pipes installed on the multiple valves, extending to the lower part of the storage cavity.

[0007] Optionally, the outer cylinder has mounting cavities on both sides, and the insulation layer is installed in the two mounting cavities respectively.

[0008] Optionally, limiting channels are provided on both sides of the inner wall of the outer cylinder, which are located between the two mounting cavities. A threaded rod is rotatably installed at the center line of the outer cylinder, and a handwheel is installed above it. A fixing plate is installed below the center line of the inner cylinder, which is threadedly engaged with the threaded rod. Limiting blocks are installed on both sides below the outer surface of the inner cylinder, which are slidably engaged with the two limiting channels respectively.

[0009] Optionally, a through groove is formed on the inner surface of each of the multiple storage cavities, and a water level plate is installed inside each of the multiple through grooves.

[0010] Optionally, one of the cushioning pads is located between the two moisture-proof pads.

[0011] This utility model has the following advantages:

[0012] This fracturing agent container for oil and gas wells consists of an outer cylinder and an inner cylinder. The inner cylinder is slidably installed inside the outer cylinder, with an insulation layer filling the space between them to keep the temperature of the inner cylinder from rising or falling. Inside the inner cylinder, multiple storage chambers are arranged in an upper and lower array. Valves are installed on the outside of each storage chamber to allow filling or discharging of the agent. Water level plates are installed on the inside of each storage chamber to facilitate monitoring of the remaining amount of the fracturing agent.

[0013] Moisture-proof pads and cushioning pads are filled between multiple storage cavities. The cushioning pads are a group of two moisture-proof pads, with the former located between the latter. The cushioning pads can absorb the vibration of the inner cylinder, while the moisture-proof pads isolate moisture to prevent the product from getting damp or the inner cylinder from being corroded.

[0014] A threaded rod is rotatably installed at the center inside the outer cylinder, and a fixed plate is installed at the bottom inside the inner cylinder, which is threadedly engaged with the threaded rod. Limiting blocks are installed on both sides of the outer cylinder, which are slidably engaged with the limiting tracks on both sides of the inner wall of the outer cylinder for limiting. The inner cylinder can be moved up and down by rotating the threaded rod. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 6 As shown, a bactericide container for fracturing oil and gas wells includes an outer cylinder 1 with an opening at the top. An inner cylinder 2, which can move up and down, is installed inside the outer cylinder 1. An insulation layer 10 is filled between the two. Multiple storage cavities 16 are formed inside the inner cylinder 2 in an array, with space between the multiple storage cavities 16. Each storage cavity 16 is filled with a buffer pad 8 and two moisture-proof pads 9. Each of the multiple storage cavities 16 has an installation hole 13 on one side. Each of the multiple installation holes 13 has a valve 6 installed inside. Each of the multiple valves 6 has a pipe 5 installed, which extends to the lower part of the storage cavity 16.

[0024] As an optional technical solution of this utility model, the outer cylinder 1 has installation cavities 11 on both sides inside, and the heat insulation layer 10 is installed in the two installation cavities 11 respectively. The heat insulation layer 10 can insulate the outer cylinder 1 and the inner cylinder 2, so as to avoid heat loss or heat absorption.

[0025] As an optional technical solution of this utility model, limit channels 12 are opened on both sides of the inner wall of the outer cylinder 1, which are located between the two mounting cavities 11. A threaded rod 3 is rotatably installed at the center line of the outer cylinder 1, and a handwheel 4 is installed above it. A fixing plate 15 is installed below the center line of the inner cylinder 2, which is threadedly engaged with the threaded rod 3. Limit blocks 14 are installed on both sides below the outer surface of the inner cylinder 2, which are slidably engaged with the two limit channels 12 respectively. After the limit blocks 14 are engaged with the limit channels 12, the movement of the inner cylinder 2 can be limited to prevent the inner cylinder 2 from shaking, so that the inner cylinder 2 can only move up and down. At the same time, the operator can hold the handwheel 4 to easily rotate the threaded rod 3.

[0026] As an optional technical solution of this utility model, a through groove 17 is provided on the inner surface of multiple storage cavities 16, and a water level plate 7 is installed inside the multiple through grooves 17. The remaining amount of raw materials in the storage cavity 16 can be viewed through the water level plate 7 to meet the needs of actual use.

[0027] As an optional technical solution of this utility model, a buffer pad 8 is located between two moisture-proof pads 9, and the two can be fixed together by glue to prevent the buffer pad 8 and the moisture-proof pad 9 from shaking.

[0028] In summary, the features, assembly method, usage process, and functions of each component in this utility model are as follows: It consists of an outer cylinder 1 and an inner cylinder 2. The inner cylinder 2 is slidably installed inside the outer cylinder 1, with an insulation layer 10 filling the space between them for heat preservation, preventing the temperature of the inner cylinder 2 from rising or falling. Multiple storage cavities 16 are formed inside the inner cylinder 2 in a vertical array. Valves 6 are installed on the outer sides of each storage cavity 16, allowing for the filling or discharging of materials into and out of the storage cavities 16. Water level plates 7 are installed on the inner sides of each storage cavity 16 to facilitate monitoring the remaining amount of disinfectant within the storage cavities 16. The cavity 16 is filled with a moisture-proof pad 9 and a buffer pad 8. The buffer pad 8 and the two moisture-proof pads 9 form a group, with the former located between the latter. The buffer pad 8 can absorb the vibration of the inner cylinder 2, while the moisture-proof pad 9 isolates moisture to prevent the product from getting damp or the inner cylinder 2 from being corroded. A threaded rod 3 is rotatably installed at the center inside the outer cylinder 1. A fixing plate 15 is installed at the bottom inside the inner cylinder 2, which is threadedly engaged with the threaded rod 3. Limiting blocks 14 are installed on both sides of the outer cylinder 2, which slide in engagement with the limiting channels 12 on both sides of the inner wall of the outer cylinder 1 for limiting. The inner cylinder 2 can be moved up and down by rotating the threaded rod 3.
