Description

Technical Field

[0001] This utility model relates to the technical field of water-based drilling, specifically to a water-based drilling waste conveying device. Background Technology

[0002] Compared to traditional oil-based drilling, water-based drilling refers to drilling operations using water as the drilling fluid. Water-based drilling is more environmentally friendly, safer, and more economical than oil-based drilling. In addition, during water-based drilling operations, a conveying device is required to transport waste.

[0003] As disclosed in announcement number CN219111029U, a water-based drilling waste collection and conveying tank device is used. The advantages of this utility model are: through the coordinated arrangement of the first motor, the driving gear, the driven gear, the first hollow rotating shaft, the feed hopper, the mounting plate, the annular filter screen, the guide hopper, and the second hollow rotating shaft, solid and liquid waste can be conveyed into the interior of the annular filter screen, and the solid waste and liquid in the solid and liquid waste can be separated by centrifugal force, which increases the solid-liquid separation function and improves the practicality and structural flexibility of the collection and conveying tank.

[0004] However, in the prior art, when using a ring filter for filtration, the ring filter is located inside the device. During long-term use, a large amount of waste adheres to the ring filter, and it is easily clogged by the waste, making it difficult to clean. Moreover, the use of a screw conveyor for transportation adds extra costs. For example, the comparative patents listed above have this problem.

[0005] To address this problem, we propose a water-based drilling waste conveying device. Utility Model Content

In addition, the use of a spiral conveyor paddle for conveying adds extra cost.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a water-based drilling waste conveying device, comprising a conveying box, a filter plate inserted into the middle of the conveying box, and a fixed frame and a support plate for support;

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-7 The present invention provides the following technical solution.

[0034] Example 1: To address the existing problems in the use of annular filter screens for filtration, where the screens are located inside the device and accumulate a large amount of waste during long-term use, making them prone to clogging and difficult to clean, and the use of a spiral conveyor increases costs, this example provides a water-based drilling waste conveying device. The device includes a conveying box 1, a filter plate 6 inserted into the middle of the conveying box 1, and a fixed frame 3 and a support plate 4 for support. A connecting mechanism is provided at the right end of the conveying box 1 to drive it to move left and right in the middle of the fixed frame 3. Fixing mechanisms 12 are provided at both the left and right ends of the front side of the filter plate 6, and these fixing mechanisms 12 enable a disassembly structure between the filter plate 6 and the conveying box 1.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, a feeding hopper 2 is provided at the upper end of the conveying box 1. The feeding hopper 2 is connected to an external support. A fixed frame 3 is fitted onto the outside of the conveying box 1, and support plates 4 are fixedly connected to both ends of the fixed frame 3. Waste from water-based drilling is added to the conveying box 1 through the feeding hopper 2. The waste is filtered by the filter plate 6 inside the conveying box 1. During the actual filtration process, a servo motor 7 can be activated. The servo motor 7 drives the eccentric wheel 8 to rotate in the movable frame 9, causing the movable frame 9 to drive the movable column 10 to slide left and right between it and the fixed frame 3. The conveyor box 1 is pushed to move back and forth in a straight line in the middle of the fixed frame 3. The lower end of the feeding hopper 2 is connected to the conveyor box 1 by a slot. The conveyor box 1 and the feeding hopper 2 do not interfere with each other when moving. The conveyor box 1 drives the movable block 5 to slide left and right between the fixed frame 3, so that the waste can be quickly filtered through the filter plate 6. A sealing gasket is set between the front side of the filter plate 6 and the conveyor box 1 to prevent the waste from leaking. The filtered waste is discharged directly through the discharge cylinder 11. A container for collection can be set below the discharge cylinder 11.

[0036] After use, such as Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the fixing mechanism 12 is composed of an auxiliary block 13, a fixing plate 14, a fixing column 15, a spring 16, and a positioning pin 17. The fixing plate 14 forms a flipping structure on the front side of the conveyor box 1, and the front side of the fixing plate 14 is fitted to the filter plate 6. The positioning pin 17 is telescopically connected to the middle of the fixing plate 14. By pulling the positioning pin 17, the positioning pin 17 slides in the fixing plate 14, and the positioning pin 17 compresses the spring 16, causing the spring 16 to undergo elastic deformation. At this time, the positioning pin 16... The positioning pin 17 disengages from the fixed column 15, thereby releasing the limit between the fixed pressure plate 14 and the fixed column 15. Then, the fixed pressure plate 14 is flipped over, and the fixed pressure plate 14 rotates with the auxiliary block 13. The fixed pressure plate 14 disengages from the filter plate 6, thereby releasing the pressing limit on the filter plate 6. Then, the filter plate 6 is pulled forward directly, and the filter plate 6 is moved out of the inside of the conveying box 1, which facilitates the cleaning of the filter plate 6 and the filtered waste, and prevents the filter plate 6 from becoming clogged during long-term use.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
