Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to an oilfield water injection sedimentation filter. Background Art

[0002] Oilfield water injection is a key measure to supplement energy to the formation during the oilfield development process. With the exploitation of the oilfield, the energy of the oil reservoir itself will be continuously consumed, resulting in a decrease in the oil reservoir pressure, a large amount of degassing of underground crude oil, an increase in viscosity, and ultimately a significant reduction in the oil well production, or even a shutdown. In order to make up for this underground deficit, maintain or increase the oil reservoir pressure, and achieve high and stable production of the oilfield, water injection has become a necessary operation.

[0003] Currently, when pumping water into the ground through a water pump, it is often necessary to install a filter at the water outlet end of the water pump to filter the water pumped into the oilfield. However, although the filter plate of the current filter can be removed, the particulate matter on its inner wall often remains for a long time, thus affecting the water filtration effect. Therefore, a new type of oilfield water injection sedimentation filter is needed to solve the above problems. Content of the Utility Model

[0004] The utility model specifically adopts the following technical solutions to achieve the above purposes:

[0005] An oilfield water injection sedimentation filter includes: a filtration chamber and a connection mechanism. The connection mechanism is used to connect the water pump and the water outlet pipe to both ends of the filtration chamber respectively. A notch is opened at the top of the filtration chamber, and a sedimentation chamber is slidably inserted into the inner wall of the notch. A slot is opened on the surface of the sedimentation chamber, and a filter plate is slidably inserted into the inner wall of the slot. The filter also includes a first limiting mechanism and a second limiting mechanism. A cover plate is rotatably installed at the top of the filtration chamber. The first limiting mechanism is used to limit the position of the filter plate on the inner wall of the slot, and the second limiting mechanism is used to limit the position of the cover plate.

[0006] Further, the connection mechanism includes two connection pipes respectively fixedly connected to both ends of the filtration chamber. Flange plates are fixedly sleeved on the surfaces of the two connection pipes, and a plurality of mounting bolts are threadedly inserted into the surfaces of the two flange plates.

[0007] Further, the first limiting mechanism includes two limiting grooves respectively opened on both sides of the inner wall of the slot. Limiting plates are slidably inserted into the inner walls of the two limiting grooves, and the two limiting plates are respectively fixedly installed on both sides of the filter plate.

[0008] Further, the second limiting mechanism includes a damping rotating shaft. A rotating rod is rotatably mounted on the surface of the sedimentation chamber through the damping rotating shaft. A pressing rod is slidably sleeved on the surface of the rotating rod. A spring in a compressed state is slidably sleeved on the surface of the rotating rod.

[0010] Further, a fixing rod is fixedly mounted on the inner wall of the filtering chamber. The baffle is rotatably sleeved on the surface of the fixing rod.

Detailed implementation mode

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] This application provides an oilfield water injection settlement filter, which is mainly used to solve the problem that when water is pumped into the ground through a water pump at present, a filter often needs to be installed at the water outlet end of the water pump to filter the water pumped into the oilfield. However, although the filter plate of the current filter can be removed, the particulate matter on its inner wall often remains for a long time, thus affecting the water filtration effect. The following technical solutions are provided and will be described in detail in conjunction with Figures 1-4 for detailed explanation:

[0022] An oilfield water injection settling filter, comprising: a filter chamber 1 and a connection mechanism 2. The user can connect the water pump and the outlet pipe to both ends of the filter chamber 1 through the connection mechanism 2 respectively. Thus, the water sprayed from the outlet end of the water pump will pass through the filter chamber 1 and be discharged from the outlet pipe. A notch 3 is provided at the top of the filter chamber 1, and a sedimentation chamber 4 is slidably inserted into the inner wall of the notch 3. A cover plate 9 is rotatably installed at the top of the filter chamber 1. Therefore, the user can limit the cover plate 9 through the second limiting mechanism 8. At the same time, a slot 5 is provided on the surface of the sedimentation chamber 4, and a filter plate 6 is slidably inserted into the inner wall of the slot 5. The user can limit the plug plate to the inner wall of the slot 5 through the first limiting mechanism 7. The main components of the connection mechanism 2 are: two flange plates 202, and connection pipes 201 are fixedly inserted into the inner walls of the two flange plates 202. At the same time, the two connection pipes 201 are respectively fixedly penetrated through both ends of the filter chamber 1. During use, after the user presses the connection devices at one end of the water pump and the outlet pipe against the surfaces of the two flange plates 202 respectively, a number of mounting bolts 203 are threadedly inserted into the surfaces of the two flange plates 202 respectively, so that the number of mounting bolts 203 are respectively threadedly inserted into the surfaces of the two connection devices, and the connection between the filter chamber 1 and the water pump and the outlet pipe can be realized. The main components of the first limiting mechanism 7 are: two limiting plates 702 respectively fixedly installed on both sides of the filter plate 6, and limiting grooves 701 are provided on both sides of the inner wall of the slot 5. During use, when the user inserts the filter plate 6 into the slot 5 and slides the two limiting plates 702 into the inner walls of the two limiting grooves 701 respectively, the limiting of the filter plate 6 on the inner wall of the slot 5 can be realized. The main components of the second limiting mechanism 8 are: a damping rotating shaft 801, a rotating rod 802 is rotatably installed on the surface of the filter chamber 1 through the damping rotating shaft 801, and a pressing rod 803 is slidably sleeved on the surface of the rotating rod 802. At the same time, a spring 804 in a compressed state is slidably sleeved on the surface of the rotating rod 802, and both ends of the spring 804 are respectively fixedly installed on the surfaces of the rotating rod 802 and the pressing rod 803. Therefore, the user can hold the pressing rod 803 and lift it up and then rotate the rotating rod 802, so as to realize the pressing rod 803 leaving the surface of the cover plate 9 and releasing the limit on the cover plate 9.

[0023] During use, the user connects the water pump and the outlet pipe to both ends of the filter chamber 1 through the connection mechanism 2 respectively, and can pump water into the interior of the filter chamber 1 through the water pump for filtration and then discharge it into the ground through the outlet pipe. When the water passes through the filter plate 6 on the surface of the sedimentation chamber 4, it will be filtered and then discharged into the outlet pipe. After use, the impurities remaining on the surface of the sedimentation chamber 4 will precipitate into it. After the user releases the limit on the cover plate 9 through the second limiting mechanism 8, the cover plate 9 is opened, the sedimentation chamber 4 is lifted out of the filter chamber 1, and the limit on the filter plate 6 is released through the first limiting mechanism 7, and the impurities precipitated on the inner wall of the sedimentation chamber 4 and the filter plate 6 can be cleaned, which fully reflects the practicability of the device.

[0024] As shown Figure 4 In some embodiments, in order to further optimize the solution, it further includes two torsion springs 10. A baffle 11 is rotatably mounted on the inner wall of the sedimentation tank 4 through the two torsion springs 10. The connection mode of the two torsion springs 10 is as follows: a fixing rod 12 fixedly mounted on the inner wall of the sedimentation tank 4, and the baffle 11 is rotatably sleeved on the surface of the fixing rod 12, and the two torsion springs 10 are both slidably sleeved on the surface of the fixing rod 12. Since one ends of the two torsion springs 10 are respectively fixedly mounted on both sides of the inner wall of the sedimentation tank 4, and the other ends of the two torsion springs 10 are respectively fixedly mounted on both sides of the baffle 11, when there is no water flow inside the filtration tank 1, the baffle 11 will block the impurities that are floating inside the sedimentation tank 4 and have not been completely sedimented under the action of the torsion springs 10, preventing them from floating into the interior of the filtration tank 1.

[0025] As shown Figure 2 In some embodiments, in order to further optimize the solution, a handle 13 with a rubber sleeve 14 fixedly sleeved on its surface is fixedly mounted on the surface of the cover plate 9. The user can hold the handle 13 to rotate the cover plate 9.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
