Description

Technical Field

[0001] The utility model relates to the technical field of emulsion pumps, and particularly to a joint structure of an emulsion pump. Background Technique

[0002] The emulsion liquid pumping station is a power device used to supply hydraulic supports in fully mechanized mining workfaces or single hydraulic props in ordinary coal mining workfaces. It mainly consists of an emulsion liquid tank, an emulsion liquid pump group (two groups), and a hydraulic control system. The emulsion liquid pumping station is mainly used in the oilfield production process to lift the already mixed oil-water emulsion to a storage tank or an injection well. Due to the relatively deep oil well depth and large oil liquid concentration, it is difficult to achieve the goal of pushing oil through natural production methods. Using an emulsion liquid pumping station can help the oilfield increase the output of the produced liquid, thereby improving the oilfield exploitation efficiency. The emulsion liquid in the oilfield needs to be pressurized and transported to corresponding equipment. The emulsion liquid pumping station can pressurize the emulsion liquid so that it can be smoothly transported to the required places, such as injection wells.

[0003] In the prior art, the return liquid pipe joints of emulsion pumps are usually all connected by flanges, and the flanges are fixed by a plurality of bolts. The return liquid pipe is usually provided with a filtering structure. After the filtering structure in the return liquid pipe is used for a period of time, the filter screen is prone to blockage, and it is not convenient to disassemble the return liquid pipe to clean or replace the filter screen, and the cleaning efficiency is low. Therefore, we have developed a joint structure of an emulsion pump. Content of the Utility Model

[0004] The purpose of the utility model is to provide a joint structure of an emulsion pump, which is convenient for quickly replacing and cleaning the filter screen cylinder, has a high replacement efficiency, and reduces the labor intensity of workers, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A joint structure of an emulsion pump, including an input pipe and an output pipe. The input pipe is arranged parallel to the upper side of the output pipe. Flanges are provided at one ends of the input pipe and the output pipe. The other ends of the input pipe and the output pipe are bent by 90°. Hoses are fixedly provided at the bent parts of the input pipe and the output pipe. Connecting pipes are fixedly provided at the other ends of the two hoses. An annular plate is arranged between the two connecting pipes. Annular grooves matched with the annular plate are respectively opened at the inner edges of the opposite sides of the two connecting pipes. The upper and lower sides of the annular plate are respectively abutted against the two annular grooves. A filter screen cylinder is arranged at the lower end of the annular plate. A positioning plate is fixedly provided between the input pipe and the output pipe. A connecting mechanism for connecting the two connecting pipes is arranged on the positioning plate.

[0007] Preferably, the connecting mechanism includes a bidirectional lead screw. A rectangular opening is formed in the middle of the positioning plate. The bidirectional lead screw is rotatably arranged in the middle of the rectangular opening through a rolling bearing. The bidirectional lead screw is vertically arranged. Push plates are symmetrically and threadedly connected to both sides of the bidirectional lead screw. The side wall of the push plate is slidably connected to the rectangular opening. One ends of the two push plates are respectively fixedly connected to the two connecting pipes.

[0008] Preferably, a turntable is fixedly provided in the middle of the bidirectional lead screw.

[0009] Preferably, anti-slip patterns are provided on the circumferential wall of the turntable.

[0010] Preferably, sealing rings are fixedly provided on both the upper and lower sides of the annular plate.

[0011] Preferably, the sealing ring is made of corrosion-resistant rubber.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] For the joint structure of the emulsifying pump, through the provided positioning plate, flange, input pipe, connecting pipe, hose, output pipe, push plate, turntable, bidirectional lead screw, sealing ring, annular plate, and filter screen cylinder, the oil liquid can be filtered through the provided filter screen cylinder. The filtered impurities are directly retained in the filter screen cylinder. When the filter screen cylinder is blocked, rotate the turntable. The turntable drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the two push plates to move in opposite directions. The push plates drive the two connecting pipes to no longer clamp the annular plate. When the distance between the connecting pipes is sufficient, the annular plate together with the filter screen cylinder can be taken out, which is convenient for quickly replacing and cleaning the filter screen cylinder, with a high replacement efficiency and reducing the labor intensity of the staff.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 3 , the present invention provides a technical solution:

[0020] A joint structure of an emulsifying pump, including an input pipe 3 and an output pipe 6. The input pipe 3 is arranged parallel to the upper side of the output pipe 6. Flanges 2 are provided at one ends of both the input pipe 3 and the output pipe 6. The other ends of both the input pipe 3 and the output pipe 6 are bent by 90°. Hoses 5 are fixedly provided at the bent parts of both the input pipe 3 and the output pipe 6. Connecting pipes 4 are fixedly provided at the other ends of both hoses 5. An annular plate 11 is provided between the two connecting pipes 4. Annular grooves matching the annular plate 11 are opened on the inner edges of the opposite sides of the two connecting pipes 4. The upper and lower sides of the annular plate 11 are respectively abutted against the two annular grooves. A filter screen cylinder 12 is provided at the lower end of the annular plate 11. A positioning plate 1 is fixedly provided between the input pipe 3 and the output pipe 6. A connecting mechanism for connecting the two connecting pipes 4 is provided on the positioning plate 1.

[0021] The connecting mechanism includes a bidirectional lead screw 9. A rectangular opening is provided in the middle of the positioning plate 1. The bidirectional lead screw 9 is rotatably arranged in the middle of the rectangular opening through a rolling bearing. The bidirectional lead screw 9 is vertically arranged. Push plates 7 are symmetrically threadedly connected to both sides of the bidirectional lead screw 9. The side walls of the push plates 7 are slidably connected to the rectangular opening. One ends of the two push plates 7 are respectively fixedly connected to the two connecting pipes 4.

[0022] A turntable 8 is fixedly provided in the middle of the bidirectional lead screw 9. The turntable 8 facilitates the rotation of the bidirectional lead screw 9. Anti-slip lines are provided on the circumferential wall of the turntable 8. The anti-slip lines improve the friction force on the side wall of the turntable 8.

[0023] Sealing rings 10 are fixedly provided on both the upper and lower sides of the annular plate 11. The sealing rings 10 improve the sealing performance. The sealing rings 10 are made of corrosion-resistant rubber rings. The corrosion-resistant rubber rings have good corrosion resistance, are not easily corroded, and have a long service life.

[0024] During use, the oil fluid can be filtered through the provided filter mesh cylinder 12, and the impurities filtered out directly remain inside the filter mesh cylinder 12. When the filter mesh cylinder 12 becomes clogged, rotate the turntable 8. The turntable 8 drives the bidirectional lead screw 9 to rotate, and the bidirectional lead screw 9 drives the two push plates 7 to move in opposite directions. The push plates 7 drive the two connecting pipes 4 to no longer clamp the annular plate 11. When the distance between the connecting pipes 4 is sufficient, the annular plate 11 together with the filter mesh cylinder 12 can be taken out, facilitating the rapid replacement and cleaning of the filter mesh cylinder 12. The replacement efficiency is relatively high, reducing the labor intensity of the staff.
