Description

Technical Field

[0001] The utility model relates to the field of material transportation, and in particular to a long-distance transportation device for powdery materials. Background Art

[0002] In the process of oil drilling, mud is an indispensable circulating medium. The mud circulates between the bottom of the well and the ground, transporting the cuttings cut by the drill bit to the ground. In addition, it also has the functions of cooling the drill bit, balancing the bottom hole pressure, and stabilizing the well wall. In order to improve the performance of the mud, various mud materials need to be added.

[0003] At present, the conventional practice of adding mud materials is to carry them manually. It is necessary to carry about 25 kg of mud materials to the mixing funnel tray on the mud weighting platform at a distance. When preparing the drilling fluid, the mud material bag needs to be cut with the cutter on the mixing funnel tray, and the drilling fluid raw materials need to be poured into the funnel for mixing. Since the mud material storage is a distance away from the mixing funnel, this is not only very labor-intensive, but also labor-intensive and inefficient for oil workers, and materials often leak. Since the material is in powder form, the dust caused by leakage will be very serious. The material waste generated during the transportation process pollutes the environment and is very likely to endanger the health of workers.

[0004] The Chinese invention patent with the publication number of "CN117163550A" and the name of "A Material Transmission Method" discloses a material transmission method, which is applied to the material transmission system, and the transmission system includes a feeding mechanism and a receiving mechanism. The transmission method includes: the feeding mechanism places the material on the receiving mechanism; the receiving mechanism transmits the material to the target station; because the method is provided with a buffer table, the material is temporarily stored on the buffer table, which can reduce the waiting time of the material for the feeding mechanism at least once, thereby reducing the overall material transmission time. This method greatly improves the efficiency of sorting, but the transportation of powdered materials will still cause material leakage. In actual application, it cannot overcome the dust hazards, environmental pollution, material waste, dust and other problems caused by the transmission of powdered materials. It not only causes material waste, but also pollutes the environment and endangers the health of workers. Utility Model Content

[0029] First Exemplary Embodiment

[0030] The present exemplary embodiment provides a device for long-distance transportation of powdered materials.

[0031] Figure 1 The schematic diagram of the structure of a long-distance powder material conveying device of an exemplary embodiment of the present utility model is shown below. Figure 1 The powder material long-distance conveying device of this exemplary embodiment is described.

[0032] In this exemplary embodiment, Figure 1 As shown in the figure, the long-distance conveying device for powdery materials includes a funnel 1, a dust cover and a bag-breaking knife mechanism. The diameter of the feed port of the funnel 1 is larger than the diameter of the discharge port of the funnel 1. A discharge pipe 3 is connected to the lower end of the discharge port of the funnel 1. A dust cover 10 is provided at the upper end of the feed port of the funnel 1, and the dust cover 10 can cover the feed port of the funnel 1. The bag-breaking knife mechanism includes a bag-breaking knife 5, a support slide 101 and a slide rail 103. The slide rail 103 is fixed in the funnel 1 and between the inner side of the feed port at a certain distance. The bag-breaking knife 5 is arranged on the slide rail 103 and is movably connected to the slide rail 103. The bag-breaking knife 5 can slide forward and backward along the length direction of the slide rail 103. The support slide 101 is arranged at the upper end of the slide rail 103. A knife bin 102 is provided on the upper side of one end of the slide rail 103, and the bag-breaking knife 5 can be stored in the knife bin 102 when not working.

[0033] In this exemplary embodiment, Figure 1 As shown in the figure, a funnel platform 4 may be provided between the dust cover 10 and the feed port of the funnel 1. A hollow hole 401 is provided on the funnel platform 4. The hollow hole 401 may be directly opposite to the inlet end of the funnel 1. The shape of the hollow hole 401 may include a hole shape. The hollow hole 401 is integrated with the funnel platform 4. The hollow shape of the hollow hole 401 may be consistent with the shape of the feed port of the funnel 1. When the bagged material passes through the hollow hole 401 and directly contacts the support slide bar 101, the support slide bar 101 can provide support for the broken bag.

[0034] In this exemplary embodiment, Figure 1As shown in , the discharge pipe 3 may include an upper tube body 301 and a lower tube body 302. The upper tube body 301 is connected to the discharge port of the funnel 1, and the lower tube body 302 is connected to the upper tube body 301. The outlet end of the lower tube body 302 faces the outside. An interface 303 may be provided outside the outlet end to connect with other platforms, such as a mud batching platform. There may be a certain angle between the connecting ends of the upper tube body 301 and the lower tube body 302. For example, 79°, 90° or 102°. In the case where the angle is 90°, the upper tube body 301 may be arranged vertically, and the lower tube body 302 may be arranged horizontally. Of course, the utility model is not limited thereto, and the specific angle of the angle between the connecting ends of the upper tube body and the lower tube body may be adjusted on site according to the specific conditions of the equipment installation. The structure of the angle can facilitate the pneumatic jet conveyor to control the compressed gas to form a negative pressure in the pipeline and efficiently transport materials.

[0035] In this exemplary embodiment, Figure 1 As shown in , a pneumatic jet conveyor 7 may be provided on the lower tube body 302. The pneumatic jet conveyor 7 has no specific fixed position on the lower tube body. Preferably, its fixed position should not be too far from the connection end of the upper tube body 301 and the lower tube body 302, otherwise it is difficult to form a negative pressure on the discharge pipe as a whole. An air inlet 702 of the pneumatic jet conveyor 7 may be provided on the lower tube body 302. An air inlet valve may be provided on the air inlet 702. The air inlet valve may be connected to a high-pressure gas source of not less than 10MPa, and high-pressure compressed air may be injected into the discharge pipe. The compressed gas flowing in the discharge pipe forms a negative pressure at the discharge port of the funnel, and the formed negative pressure can transport the powdered material in the funnel to the outside, for example, to the mud batching platform. In addition, the pneumatic jet conveyor 7 may be provided with an air outlet 701 on the inner wall of the discharge pipe. The air outlet 701 may face the same direction as the outlet end of the lower tube body.

[0036] In this exemplary embodiment, Figure 1 As shown in , a pneumatic vibrator 8 may be provided on the outer wall of the side wall of the funnel 1. When compressed air enters the funnel 1, the pneumatic vibrator 8 may be driven to vibrate.

[0037] In this exemplary embodiment, Figure 1 As shown in the figure, a funnel bracket 2 is arranged outside the funnel 1, and the funnel bracket 2 can fix the funnel 1. For example, the funnel can be fixed in the funnel bracket while sitting or lying down. The funnel is provided with stability. The funnel bracket is arranged at the lower end of the funnel platform.

[0038] In this exemplary embodiment, Figure 1 As shown in the figure, a plurality of rubber shock-absorbing pads 9 are evenly arranged between the funnel platform 4 and the funnel bracket 2. For example, 3, 4 or 6 rubber shock-absorbing pads can bring better shock-absorbing effect to the long-distance conveying device of powdery materials.

[0039] In this exemplary embodiment, Figure 1 As shown in , the bag breaking knife mechanism may further include an operating handle 6, one end of the operating handle 6 is connected to the bag breaking knife 5, and the other end passes through the funnel bracket 2 and is arranged outside the funnel bracket 2. The operating handle 6 can drive the bag breaking knife 5 to move on the slide rail 103. For example, the operating handle 6 can be rotated, and then the operating handle 6 can be pushed and pulled to move the bag breaking knife 5 out of the knife bin 102 or move the bag breaking knife 5 back to the knife bin 102.

[0040] The conveying process of the long-distance conveying device for powdery materials of the utility model may include: opening the air inlet valve, allowing compressed air to enter the air inlet valve, using the compressed air as the power, and utilizing the ejection effect of the high-speed airflow, the air in the funnel and the discharge pipe is attracted and ejected out of the discharge pipe. At the same time, the compressed air enters the pneumatic vibrator, driving the pneumatic vibrator and driving the funnel to vibrate. Rotate the operating handle, and then push the handle to push the bag-breaking knife from the knife chamber to the working position. Put the bag containing the mud material on the funnel platform, and push the bag. During this process, the slide bar in the funnel will support the bag, and the bag-breaking knife will cut the bag to make the mud material fall into the funnel. The powdery material falling into the funnel will enter the pneumatic jet conveyor under the action of vacuum suction, and then enter the mixing funnel on the mud weighting platform or other required positions through the conveying hose under the push of the airflow. The pneumatic vibrator vibrates, and the funnel shakes off the mud material on its side wall and the accumulated mud material, so as to ensure the smooth conveying of the mud material. In addition, several rubber shock-absorbing pads are installed between the funnel and the funnel bracket, which is more conducive to the shock-absorbing effect of the entire equipment. Push the operating handle forward and backward, and lift the bag to allow all the materials in the bag to enter the funnel to complete the feeding operation.

[0041] In summary, the advantages of the present invention may include at least one of the following:

[0042] (1) The conveying pipe of the conveying device provided by the utility model is configured as an angled elbow, which can be connected to the pipeline of the external platform, and the pneumatic jet conveyor delivers high-pressure airflow to the discharge pipe, forming a negative pressure in the pipe to prevent dust from overflowing;

[0043] (2) The conveying device provided by the utility model is provided with a bag breaking knife mechanism inside the device, so as to realize bag breaking and transportation of powder materials in the device, thereby avoiding material leakage and dust pollution;

[0044] (3) The conveying device provided by the utility model is provided with a rubber shock-absorbing pad between the funnel bracket and the funnel platform to reduce the influence of the pneumatic vibrator on the funnel bracket.

[0045] Although a powder material long-distance conveying device has been described above in conjunction with exemplary embodiments, it should be clear to those skilled in the art that various modifications and changes may be made to the exemplary embodiments of the utility model without departing from the spirit and scope defined by the claims.
