Description

Technical Field

[0001] The utility model relates to the technical field of injection devices, in particular to a demulsifier injection device. Background Art

[0002] Petroleum demulsifier is a chemical used to treat petroleum and petroleum products. It is an additive used to break up and disperse oil-water emulsions. During extraction, transportation and storage, petroleum often mixes with water to form emulsions, which can lead to decreased fluidity of the oil, deterioration of oil quality, and difficulty in handling and separation.

[0003] In the prior art, in order to allow the demulsifier to fully react with the oil, a flap valve is usually installed inside the injection device. The oil demulsifier is injected intermittently in batches by controlling the closure of the valve. However, after long-term use, the flap of this valve is easily deformed due to the long-term downward pressure. At this time, a gap will be generated between the flap and the discharge pipe, thereby reducing the sealing of the valve. At the same time, the demulsifier inside the injection device is prone to stratification after being left stationary for a long time. When the stratified demulsifier is injected into the oil, the demulsifier's effect on eliminating the emulsion will be reduced. In view of this, we propose a demulsifier injection device. Summary of the Invention

[0004] The purpose of the utility model is to provide a demulsifier injection device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, one of the objectives of the present invention is to provide a demulsifier injection device, including an oil storage device, the top of the oil storage device is fixedly connected to a storage hopper, the bottom of the storage hopper is fixedly connected to a discharge pipe, the lower end of the discharge pipe passes through the upper side wall of the oil storage device, and an inverted cylinder with an opening facing downward is slidably provided inside the discharge pipe, the side wall of the inverted cylinder is symmetrically provided with two through grooves, a reciprocating mechanism is provided on the inverted cylinder, the upper surface of the oil storage device is rotatably connected to a lower ring, and a rotating mechanism is provided on the lower ring. When the rotating mechanism drives the lower ring to rotate, the lower ring drives the reciprocating mechanism and the inverted cylinder to reciprocate vertically. When the inverted cylinder moves to the top, the through groove connects the inverted cylinder with the interior of the storage hopper. A stirring mechanism is provided on the storage hopper, and when the lower ring rotates, the stirring mechanism stirs the demulsifier in the storage hopper.

[0006] As a further improvement of the present technical solution, the reciprocating mechanism includes an extension plate fixedly connected to the side wall of the inverted cylinder, the extension plate is located below the discharge pipe, both ends of the extension plate are fixedly connected to vertical rods, the upper ends of the two vertical rods pass through the upper side wall of the oil storage device and are fixedly connected to an upper ring, the outer sliding sleeve of the vertical rod is provided with a spring, and the two ends of the spring are respectively fixedly connected to the lower surface of the upper ring and the upper surface of the oil storage device.

[0007] As a further improvement of the present technical solution, a plurality of tooth blocks are fixedly connected to the annular array on the lower surface of the upper ring, one side of the tooth block is set as an inclined surface, and a plurality of driving blocks are fixedly connected to the annular array on the upper surface of the lower ring. When the lower ring drives the driving block to rotate, the upper end of the driving block contacts the inclined surface of the tooth block.

[0008] As a further improvement of the present technical solution, the upper surface of the storage hopper is fixedly connected to an end cover, the stirring mechanism includes a rotating shaft rotatably connected to the side wall of the end cover, the side wall of the rotating shaft is fixedly connected to a stirring blade, and the stirring blade is arranged inside the storage hopper.

[0009] As a further improvement of the present technical solution, the upper end of the rotating shaft is fixedly connected to an N-shaped frame, the upper surface of the lower ring is symmetrically fixedly connected to two ferrules, and the lower end of the N-shaped frame is slidably arranged inside the two ferrules.

[0010] As a further improvement of the present technical solution, the rotating mechanism includes a mounting frame fixedly connected to the upper surface of the oil storage device, a motor is fixedly connected to the top of the mounting frame, the lower end of the motor output shaft passes through the upper side wall of the mounting frame and is coaxially fixedly connected to the driving gear, the side wall of the lower ring is concentrically fixedly connected to the driven gear, and the driven gear is meshed with the driving gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This demulsifier injection device, when the motor drives the lower ring to rotate, causes the inverted barrel to move vertically back and forth. When the through slot on the inverted barrel moves to the internal position of the storage hopper, the demulsifier in the storage hopper flows into the oil storage device through the inverted barrel. When the inverted barrel moves downward to block the through slot by the feed pipe, the demulsifier can no longer flow into the inverted barrel. Then, by causing the through slot to move vertically back and forth, it continuously switches between a connected state and a blocked state, intermittently injecting the demulsifier into the oil storage device, allowing the demulsifier to fully react with the oil. This intermittent feeding mechanism will not cause demulsifier leakage due to excessive pressure after long-term use, thereby improving the sealing performance of the device.

[0013] 2. When the motor drives the lower ring to rotate, the demulsifier injection device causes the stirring blades to stir the demulsifier inside the storage hopper, eliminating the stratification phenomenon caused by the demulsifier standing for a long time, and mixing the oil inside the oil storage device with the stirred demulsifier, ensuring the demulsifier's effect of eliminating the emulsion in the oil.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0028] See also Figure 1-Figure 2As shown, one of the purposes of this embodiment is to provide a demulsifier injection device, including an oil storage device 1, a storage hopper 2 is fixedly connected to the top of the oil storage device 1, and demulsifier is contained in the storage hopper 2. A discharge pipe 21 is fixedly connected to the bottom of the storage hopper 2, and the lower end of the discharge pipe 21 passes through the upper side wall of the oil storage device 1. An inverted cylinder 3 with an opening facing downward is slidably provided inside the discharge pipe 21, and two through grooves 31 are symmetrically provided on the side wall of the inverted cylinder 3. A reciprocating mechanism 4 is provided on the inverted cylinder 3. The upper surface of the oil storage device 1 is rotatably connected to a lower ring 5, and a rotating mechanism 6 is provided on the lower ring 5. When the rotating mechanism 6 drives the lower ring 5 to rotate, the lower ring 5 drives the reciprocating mechanism 4 and the inverted cylinder 3 to move back and forth vertically. When the inverted cylinder 3 moves upward, the through groove 31 is moved from the discharge pipe 2 1 moves from the inside of the storage hopper 2 to the inside of the storage hopper 2, the through groove 31 connects the inverted cylinder 3 with the inside of the storage hopper 2, and the demulsifier in the storage hopper 2 flows into the inside of the inverted cylinder 3 through the through groove 31, and the demulsifier in the inverted cylinder 3 then flows into the inside of the oil storage device 1. The top of the inverted cylinder 3 is set to a pointed top, so that the inverted cylinder 3 can be moved into the inside of the storage hopper 2 more effortlessly. When the inverted cylinder 3 moves from top to bottom, so that the through groove 31 moves to the inside of the discharge pipe 21, the inner wall of the discharge pipe 21 blocks the through groove 31, so that the demulsifier can no longer flow into the inside of the inverted cylinder 3. By changing the position of the inverted cylinder 3 in the discharge pipe 21, the demulsifier can be intermittently added to the inside of the oil storage device 1, so that the demulsifier can fully react with the oil in the oil storage device 1, thereby improving the reaction effect of the demulsifier and the oil.

[0029] In order to drive the lower ring 5 to rotate, the structure of the rotating mechanism 6 is detailed below. Figure 3 and Figure 4 The rotating mechanism 6 includes a mounting frame 61 fixedly connected to the upper surface of the oil storage device 1, and a motor 62 is fixedly connected to the top of the mounting frame 61. The lower end of the output shaft of the motor 62 passes through the upper side wall of the mounting frame 61 and is coaxially fixedly connected to a driving gear 63. The side wall of the lower ring 5 is concentrically fixedly connected to a driven gear 64. The driven gear 64 meshes with the driving gear 63. After the motor 62 is started, its output shaft drives the driving gear 63 to rotate, and through the meshing transmission of the driving gear 63 and the driven gear 64, the driven gear 64 drives the lower ring 5 to rotate.

[0030] In order to make the inverted cylinder 3 move vertically back and forth during the rotation of the lower ring 5, the structure of the reciprocating mechanism 4 is detailed below. Figure 2-Figure 5The reciprocating mechanism 4 includes an extension plate 42 fixedly connected to the side wall of the inverted cylinder 3. The extension plate 42 is located below the discharge pipe 21. Both ends of the extension plate 42 are fixedly connected to a vertical rod 43. The upper ends of the two vertical rods 43 pass through the upper side wall of the oil storage device 1 and are fixedly connected to an upper ring 45. The upper ring 45 is located above the lower ring 5. The vertical rod 43 is vertically arranged so that the inverted cylinder 3 and the upper ring 45 can only move vertically along the axis of the vertical rod 43. A spring 44 is provided on the outer sliding sleeve of the vertical rod 43. The two ends of the spring 44 are respectively fixedly connected to the lower surface of the upper ring 45 and the upper surface of the oil storage device 1. A plurality of tooth blocks 46 are fixedly connected to the annular array on the lower surface of the upper ring 45. One side of the tooth block 46 is set as an inclined surface. The upper surface of the lower ring 5 is fixedly connected to a plurality of tooth blocks 46 in an annular array. There are a number of drive blocks 51, which are approximately triangular prism structures. When the lower ring 5 rotates, several drive blocks 51 rotate synchronously with the lower ring 5. When the rotating drive block 51 contacts the inclined surface of the tooth block 46, the rotating drive block 51 pushes the tooth block 46 upward through the inclined surface in contact with the tooth block 46, so that the drive block 51 lifts the tooth block 46 upward. When the tooth block 46 moves upward, the upper ring 45, the vertical rod 43, the extension plate 42 and the inverted cylinder 3 move upward synchronously. At this time, the distance between the upper ring 45 and the oil storage device 1 increases, and the spring 44 elastically stretches. When the rotating drive block 51 disengages from the tooth block 46, the spring 44 rebounds and pulls the upper ring 45 downward, causing the inverted cylinder 3 to move downward synchronously, thereby realizing the vertical reciprocating movement of the inverted cylinder 3.

[0031] When the demulsifier in the storage hopper 2 is left standing for a long time, the demulsifier may be stratified. When the stratified demulsifier is added to the oil, the effect of the demulsifier in eliminating the emulsion in the oil will decrease. Therefore, when the demulsifier that has been standing for a long time is added to the oil, the demulsifier needs to be stirred to eliminate the stratification of the demulsifier. In order to facilitate the stirring of the demulsifier, a stirring mechanism 7 is provided on the storage hopper 2. When the lower ring 5 rotates, the stirring mechanism 7 stirs the demulsifier in the storage hopper 2. The structure of the stirring mechanism 7 is detailed below. Figure 2 and Figure 5The upper surface of the storage hopper 2 is fixedly connected to the end cover 22, and the stirring mechanism 7 includes a rotating shaft 71 rotatably connected to the side wall of the end cover 22. The side wall of the rotating shaft 71 is fixedly connected to a stirring blade 72. The stirring blade 72 is arranged inside the storage hopper 2, and the upper end of the rotating shaft 71 is fixedly connected to an N-shaped frame 73. The upper surface of the lower ring 5 is symmetrically fixedly connected with two ferrules 52. The lower end of the N-shaped frame 73 is slidably arranged inside the two ferrules 52. When the lower ring 5 rotates, the two ferrules 52 rotate synchronously with the lower ring 5. The two rotating ferrules 52 drive the N-shaped frame 73, the rotating shaft 71 and the stirring blade 72 to rotate. The stirring blade 72 stirs the demulsifier inside the storage hopper 2 to eliminate the stratification phenomenon of the demulsifier caused by long-term standing, so that the oil inside the oil storage device 1 is mixed with the stirred demulsifier, ensuring the effect of the demulsifier in eliminating the emulsion in the oil.
