Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a device for detecting suspended solids in water injected into an oilfield water injection system. Background Technology

[0002] A control valve is installed on the outlet pipeline. When the valve is opened, water from the injection well can flow out. When testing the water quality in the water injection system, a filter membrane box is required. The suspended matter trapped on the filter membrane box is used to determine whether the water quality at the injection well or water treatment equipment exceeds the standard.

[0003] Existing oilfield water injection wellhead suspended solids detection devices involve directly opening the filter screen's restriction during removal and then pulling it out. This process causes the filter screen to vibrate, dislodging impurities that fall back into the device, affecting subsequent detection. Therefore, a new suspended solids detection device for oilfield water injection systems is proposed to address these issues. Utility Model Content

[0033] The utility model will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0034] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0035] like Figure 1-5 As shown, this utility model discloses a device for detecting suspended solids in oilfield water injection systems, comprising:

[0036] Water outlet pipe 110;

[0037] A detection box 120 is disposed on and connected to the water outlet pipe 110. A fixing frame 121 is provided in the middle of the side wall of the detection box 120, and a matching mounting plate 122 is provided at the fixing frame 121. Preferably, a handle 122a is provided on the mounting plate 122. More preferably, a rubber pad 123 is provided on the outer end face of the mounting plate 122, and the rubber pad 123 is sealed to the inside of the fixing frame 121.

[0038] The mounting frame 130 is slidably disposed in the middle of the detection box 120 perpendicular to the fluid flow direction in the water outlet pipe 110; a filter screen 131 is provided on the left / right side of the mounting frame 130, and a fixing plate 132 is provided on the right / left side of the mounting frame; one side of the mounting frame 130 is fixedly connected to the mounting plate 130.

[0039] A sliding groove 133 is disposed within the fixed plate 132;

[0040] A movable plate 134 is disposed within the sliding groove 133 and is adapted to the sliding groove 133;

[0041] A driving mechanism, connected to the movable plate 134, is used to drive the movable plate 134 to move along the sliding groove 133 to cover the filter screen 131. Preferably, the driving mechanism includes: a threaded hole horizontally disposed within the movable plate 134; a threaded rod 141 horizontally disposed within the threaded hole, with an external thread on the outer periphery of the threaded rod 141 that matches the threaded hole; the outer end of the threaded rod 141 passes through a first through hole and a second through hole respectively disposed on the fixed plate 132 and the mounting plate 122, and extends to the outer side of the mounting plate 122; and an internal hexagonal groove disposed at the outer end of the threaded rod 141; wherein internal threads matching the external threads are respectively provided in the first through hole and the second through hole.

[0042] During use, when the filter screen 131 needs to be removed, the operator inserts a hex wrench into the internal hexagonal groove on the threaded rod 141, and then rotates the hex wrench to drive the threaded rod 141. The threaded rod 141 drives the moving plate 134 to move along the sliding groove 133, covering the filter screen 131. This prevents the filter screen 131 from being directly exposed to the outside when it is removed, and thus prevents the filtered impurities on the filter screen 131 from falling off due to shaking.

[0043] In another embodiment, the driving mechanism includes: a threaded hole horizontally disposed within the movable plate 134; a threaded rod 141 horizontally disposed within the threaded hole, with an external thread on the outer periphery of the threaded rod 141 adapted to the threaded hole; the outer end of the threaded rod 141 passes through a first through hole and a second through hole respectively disposed on the fixed plate 132 and the mounting plate 122, and extends to the outer side of the mounting plate 122; and an internal hexagonal groove disposed at the outer end of the threaded rod 141; wherein an internal thread adapted to the external thread is provided in the first through hole and the second through hole respectively.

[0044] In another embodiment, it further includes: a first positioning plate 151 and a second positioning plate 152, which are respectively horizontally arranged at the center of the top wall and bottom wall of the detection box 120. Positioning grooves 151a and 152a are respectively provided on the lower edge of the first positioning plate 151 and the upper edge of the second positioning plate 152. The positioning grooves 151a and 152a are adapted to the upper and lower ends of the mounting frame 130, respectively, to enable the mounting frame 130 to be slidably arranged in the detection box 120.

[0045] In another embodiment, the system further includes: a chamfered structure 134a disposed at the upper and lower corners of the outer side of the movable plate 134; a first slot and a second slot disposed at the outer ends of the upper and lower edges of the fixed plate 132, respectively; a first sliding rod 161 and a second sliding rod 162 adapted to the first slot and the second slot, respectively; a first fixing block 163 and a second fixing block 164 disposed at the lower end of the first sliding rod 161 and the upper end of the second sliding rod 162, respectively; a first return spring 165 and a second return spring 1666. 6. The upper and lower ends of the first return spring 165 are respectively connected to the fixed plate 121 and the first fixed block 163, and the upper and lower ends of the second return spring 166 are respectively connected to the second fixed block 164 and the fixed plate 121; the first fixed sleeve 167 and the second fixed sleeve 168 are respectively disposed in the detection box 120 at positions corresponding to the first sliding rod 161 and the second sliding rod 162, for inserting or popping the first sliding rod 161 and the second sliding rod 162 to lock and release the mounting frame 130. When the movable plate 134 moves, the chamfered structure 134a of the movable plate 134 no longer contacts the first fixed block 163 and the second fixed block 164, thus no longer pressing the first fixed block 163 and the second fixed block 164. Under the elastic force of the first return spring 165 and the second return spring 166, the first fixed block 163 and the second fixed block 164 respectively drive the first sliding rod 161 and the second sliding rod 162 to slide into the sliding groove 133. At this time, the first sliding rod 161 and the second sliding rod 162 slide out from the inside of the first fixed sleeve 167 and the second fixed sleeve 168 respectively, thereby releasing the mounting frame 130. This allows the filter screen 131 to be removed by pulling the handle 122a, avoiding the need to disassemble the mounting plate 122 later, and facilitating disassembly and maintenance by the staff.

[0046] In another embodiment, a handle 122a is provided on the mounting plate 122.

[0047] In another embodiment, the mounting plate 122 is further provided with a rubber pad 123 on its outer end face, and the rubber pad 123 is sealed to the inside of the fixing frame 121.

[0048] In summary, this utility model provides a suspended solids detection device for oilfield water injection systems, which is equipped with a movable plate 134 that can cover the filter screen 131 during the removal process, preventing impurities on the filter screen 131 from being shaken off due to shaking.

[0049] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
