Description

Technical Field

[0001] This utility model relates to the field of cement expansion agent technology, and in particular to a production equipment for preparing oil well cement expansion agent. Background Technology

[0002] Both cement powder and expanding agent are dry powders. After being stored for a long time, cement powder and expanding agent are prone to moisture and clumping. When mixing cement powder and expanding agent, it is necessary to break up the clumps during the mixing process. Existing cement powder and expanding agent mixing equipment cannot mix cement powder and expanding agent evenly, nor can it efficiently break up the clumps.

[0003] Chinese utility model patent CN210699707U discloses a mixing and crushing production device for oil well cement expanding agent, including a box body. The bottom end of the box body is fixedly mounted on a support, and a motor is fixedly mounted in the middle of the top end of the box body. The output shaft of the motor is connected to a stirring rod via a coupling, and the stirring rod is rotatably mounted inside the box body. A feed hopper is provided at the top end of the box body, and an opening and closing plate is installed at the bottom end of the feed hopper via a spring hinge. An inverted conical bottom shell is provided at the bottom end of the box body. An annular air guide plate is fixedly fitted on the outer side of the inverted conical bottom shell, and a jet plate is provided on the inner side of the inverted conical bottom shell. The annular air guide plate and the jet plate are connected through an air passage, and jet holes are evenly opened on the jet plate, so as to uniformly mix cement powder and expanding agent and efficiently break up the clumps of cement powder and expanding agent.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: The device uses a stirring rod installed inside the chamber to mix and break up clumps of cement powder and expanding agent. During use, workers need to inject cement powder and expanding agent into the feed hopper, causing the opening and closing plate to rotate downwards, allowing the cement powder and expanding agent to move over the plate into the chamber. However, in actual use, because the opening and closing plate is installed at the bottom of the feed hopper via a spring hinge, and the spring force coefficient is fixed, when workers pour materials, the opening and closing plate is prone to rebounding under the spring's action due to the small amount of material passing through. This can cause some material to move up and down, resulting in dust and a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a production equipment for preparing oil well cement expansion agents.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a production equipment for preparing oil well cement expansion agent, comprising a support, a box mounted on the support, an inverted conical bottom shell mounted on the box, a feed hopper mounted on the box, an air pump mounted on the support, an air guide plate connected to the air pump, and a stirring device mounted on the box. The bottom of the feed hopper is hinged with an opening and closing plate, and two arc-shaped blocks are symmetrically arranged on the inner top wall of the box. The arc-shaped blocks are provided with a limiting component for limiting the opening and closing plate.

[0007] By adopting the above technical solution, when workers need to produce oil well cement expanding agent, they need to put cement powder and expanding agent into the feed hopper in sequence. At this time, the workers need to close the limiting component and slide the arc-shaped rod downwards, so that the opening and closing plate can slide downwards with the arc-shaped rod, thereby making the opening and closing plate press against the limiting rod. At this time, the opening and closing plate remains open under the action of gravity, thereby reducing the probability of the opening and closing plate blocking the cement powder and expanding agent, thus reducing the probability of dust generation and improving the user experience for workers. Furthermore, workers only need to turn on the mixing device to mix and crush the cement powder and expanding agent.

[0008] Furthermore, a first arc-shaped groove is provided on the side wall of each of the two arc-shaped blocks, and two second arc-shaped grooves are respectively connected to the two first arc-shaped grooves through the inner top wall of the box. The limiting component includes two arc-shaped rods respectively slidably disposed in the two first arc-shaped grooves and a limiting device disposed on the box for limiting the opening and closing plate. The arc-shaped rods are fixed to the opening and closing plate.

[0009] Furthermore, the limiting device includes a fixed rod that is mounted on two arc-shaped rods and a connecting rod that is slidably mounted on the fixed rod, and the upper surface of the box is provided with a connecting groove that matches the connecting rod.

[0010] By adopting the above technical solution, after the cement powder is added, the operator needs to reset the opening and closing plate. At this time, the operator needs to pull the fixing rod upward, which will cause the two arc-shaped rods to move upward with the fixing rod. Subsequently, when the opening and closing plate moves to the highest point, the operator needs to slide the connecting rod downward, which will connect the lower end of the connecting rod with the connecting groove, thereby keeping the fixing rod stable under the action of the connecting rod, and thus keeping the switch plate and the arc-shaped rod stable, thereby allowing the switch plate to close the feed hopper.

[0011] Furthermore, a limiting rod for limiting the opening and closing plate is fixed on the inner wall of the box.

[0012] Furthermore, a first magnet block is fixed on the side wall of the limiting rod, and a second magnet block that attracts the first magnet block is embedded on the side wall of the opening and closing plate.

[0013] By adopting the above technical solution, when the opening and closing plate moves downward, the limiting rod blocks the opening and closing plate, thereby causing the first magnet block and the second magnet block to attract each other, thus improving the stability of the opening and closing plate at this time and reducing the probability of the opening and closing plate rotating up and down under the action of the material.

[0014] Furthermore, limit blocks are fixed at both the upper and lower ends of the connecting rod.

[0015] By adopting the above technical solution, the probability of the connecting rod and the fixed rod separating from each other is reduced, thereby improving the user experience for staff.

[0016] Furthermore, the cross-section of the connecting rod is rectangular.

[0017] Furthermore, a conical block is fixed to the bottom surface of the connecting rod.

[0018] By adopting the above technical solution, the conical block reduces the probability that the operator must align the connecting rod with the connecting groove, thereby reducing the difficulty of connecting the connecting rods to each other and improving the operator's user experience.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, when workers need to produce oil well cement expanding agent, they need to put cement powder and expanding agent into the feed hopper in sequence. At this time, workers need to close the limiting component and slide the arc-shaped rod downwards, so that the opening and closing plate can slide downwards with the arc-shaped rod, thereby making the opening and closing plate press against the limiting rod. At this time, the opening and closing plate remains open under the action of gravity, thereby reducing the probability of the opening and closing plate blocking the cement powder and expanding agent, thus reducing the probability of dust generation and improving the user experience for workers. Furthermore, workers only need to turn on the mixing device to mix and crush the cement powder and expanding agent;

[0021] 2. In this application, after the cement powder is added, the operator needs to reset the opening and closing plate. At this time, the operator needs to pull the fixing rod upward, which will cause the two arc-shaped rods to move upward with the fixing rod. Subsequently, when the opening and closing plate moves to the highest point, the operator needs to slide the connecting rod downward, which will connect the lower end of the connecting rod with the connecting groove, thereby keeping the fixing rod stable under the action of the connecting rod, and thus keeping the switch plate and the arc-shaped rod stable, thereby closing the feed hopper with the switch plate;

[0022] 3. In this application, when the opening and closing plate moves downward, the limiting rod blocks the opening and closing plate, thereby causing the first magnet block and the second magnet block to attract each other, which improves the stability of the opening and closing plate at this time and reduces the probability of the opening and closing plate rotating up and down under the action of the material.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-5 As shown in the embodiment of this application, a production device for preparing oil well cement expanding agent is disclosed, including a support 1, a box 11, an inverted conical bottom shell 2, a feed hopper 21, an air pump 3, an air guide plate 31, a stirring device 4, a hinged plate 41, an arc-shaped block 5, a limiting component 6, a limiting rod 8, a first magnet block 81, a second magnet block 82, a limiting block 83, and a conical block 9. The box 11 is mounted on the support 1, and the inverted conical bottom shell 2 is mounted on the box 11. The feed hopper 21 is disposed on the box 11 for feeding materials. The air pump 3 is disposed on the support 1, and the air guide plate 31 is connected to the air pump 3. The stirring device 4 is disposed on the box 11. The hinged plate 41 is a plate-shaped structure, and the hinged plate 41 is hinged to the bottom of the feed hopper 21. The arc-shaped block 5 is a block-shaped structure with a circular arc cross-section, and two arc-shaped blocks 5 are provided and symmetrically disposed on the inner top wall of the box 11.

[0031] Each of the two arc-shaped blocks 5 has a first arc-shaped groove 51 on its sidewall. Two second arc-shaped grooves 52, each communicating with one of the first arc-shaped grooves 51, are formed through the inner top wall of the housing 11. A limiting component 6 is mounted on the arc-shaped blocks 5 to limit the opening and closing plate 41. The limiting component 6 includes an arc-shaped rod 61 and a limiting device 7. The arc-shaped rod 61 is a rod-shaped structure with a circular arc cross-section. Two arc-shaped rods 61 are provided and slidably mounted within the two first arc-shaped grooves 51, and the arc-shaped rods 61 are fixed to the opening and closing plate 41.

[0032] A limiting device 7 is installed on the housing 11 to limit the opening and closing plate 41. The limiting device 7 includes a fixing rod 71 and a connecting rod 72. The fixing rod 71 is a rectangular rod structure and is mounted on two arc-shaped rods 61. The connecting rod 72 is a rectangular rod structure and is slidably mounted on the fixing rod 71. A connecting groove matching the connecting rod 72 is provided on the upper surface of the housing 11.

[0033] After the cement powder is added, the operator needs to reset the opening and closing plate 41. At this time, the operator needs to pull the fixing rod 71 upward, which will cause the two arc-shaped rods 61 to move upward with the fixing rod 71. Then, when the opening and closing plate 41 moves to the highest point, the operator needs to slide the connecting rod 72 downward, which will connect the lower end of the connecting rod 72 with the connecting groove, thereby keeping the fixing rod 71 stable under the action of the connecting rod 72, and thus keeping the switch plate and the arc-shaped rods 61 stable, so that the switch plate closes the feed hopper 21.

[0034] The limiting rod 8 is a rectangular rod-shaped structure, fixed to the inner wall of the housing 11, and used to limit the opening and closing plate 41. The first magnet block 81 is a block-shaped structure, fixed to the side wall of the limiting rod 8. The second magnet block 82 is a block-shaped structure, embedded in the side wall of the opening and closing plate 41, and the second magnet block 82 and the first magnet block 81 are attracted to each other.

[0035] When the opening and closing plate 41 moves downward, the limiting rod 8 blocks the opening and closing plate 41, thereby causing the first magnet block 81 and the second magnet block 82 to attract each other, thus improving the stability of the opening and closing plate 41 at this time and reducing the probability of the opening and closing plate 41 rotating up and down under the action of the material.

[0036] The limiting block 83 is a block-shaped structure, and two limiting blocks 83 are provided and fixed sequentially to the upper and lower ends of the connecting rod 72. The limiting block 83 reduces the probability of the connecting rod 72 and the fixing rod 71 separating from each other, thereby improving the user experience for the staff.

[0037] The conical block 9 is a block-shaped structure with a square pyramidal cross-section, and it is fixed to the bottom surface of the connecting rod 72. The conical block 9 reduces the probability that the operator must align the connecting rod 72 with the connecting groove, thereby reducing the difficulty of connecting the connecting rods 72 to each other and improving the operator's user experience.

[0038] The operating principle of the production equipment for preparing oil well cement expanding agent in this embodiment is as follows: When the operator needs to produce oil well cement expanding agent, the operator needs to put cement powder and expanding agent into the feed hopper 21 in sequence. At this time, the operator needs to close the limiting component 6 and slide the arc rod 61 downward, so that the opening and closing plate 41 slides downward with the arc rod 61, thereby pressing the opening and closing plate 41 against the limiting rod 8. At this time, the opening and closing plate 41 remains open under the action of gravity, thereby reducing the probability of the opening and closing plate 41 blocking the cement powder and expanding agent, thus reducing the probability of dust, thereby improving the operator's user experience. Furthermore, the operator only needs to turn on the stirring device 4 to mix and crush the cement powder and expanding agent.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
