Description

Technical Field

[0001] This utility model relates to the technical field of mud pump suction pipelines, specifically a tooling for a multi-port suction pipeline of a mud pump. Background Technology

[0002] A mud pump is a machine that delivers mud or flushing fluid such as water into the borehole during the drilling process. It is an important part of drilling equipment. The mud pump suction line is a pipeline system that connects the mud pump and the mud storage equipment. It is mainly used to transport mud from the storage equipment to the hydraulic end of the mud pump. During the use of the mud pump, the stability and efficiency of the suction line directly affect the working performance of the pump.

[0003] As disclosed in CN207278494U, a mud pump suction pipe for easy mud cleaning includes an outer pipe and an inner pipe. The outer pipe has openings at both ends and an inlet on its side wall for conveying mud. The inner pipe is semi-circular and located inside the outer pipe, with semi-circular openings at both ends. Inlets are located at positions corresponding to the inlets of the outer and inner pipes. A support frame is provided on the inner pipe wall, and a limiting block is provided on the outer pipe wall to restrict the rotation of the inner pipe. This design allows for quick and efficient cleaning of sediment at the bottom of the suction pipe's inner wall. The cleaning process is convenient and fast, and there is no need to worry about damage to the inner wall of the suction pipe during cleaning.

[0004] However, in the existing technology, the inner wall of the pipe is in direct contact with the mud, which causes severe wear during long-term use. When the mud is sucked in, there is a lack of mud filtration components, which can easily cause the mud to clog the pipe and even damage the mud pump, affecting the service life of the mud pump. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a multi-port suction pipeline fixture for mud pumps. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-port suction pipe tooling for a mud pump, in order to solve the problems mentioned in the background art, where the inner wall of the pipe is in direct contact with the mud, resulting in severe wear during long-term use, and the lack of a mud filtration component when suctioning mud, which makes the mud easy to clog the pipe and even damage the mud pump, thus affecting the service life of the mud pump.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-port suction pipeline tooling for a mud pump, comprising a main pipeline, a first flange, branch pipes, and a second flange;

[0010] A filter assembly is provided on the front side of the branch pipe. The branch pipe is connected to an external mud source through the filter assembly. The filter assembly includes a filter box, a fixed cover plate that flips at the bottom of the filter box, and a filter screen inserted into the filter box. The filter screen has a detachable structure in the filter box.

[0011] Preferably, a first flange is welded to the upper end and both the left and right ends of the main pipe, and a second flange is welded to the front side of the branch pipe.

[0012] Preferably, a third flange is provided on the rear side of the filter box, and a fourth flange is provided on the front side of the filter box. The third flange and the second flange are mutually limited by bolts and nuts in a threaded engagement.

[0013] A sealing ring is fitted between the third flange and the second flange.

[0014] Preferably, the fixed cover plate is hinged at the lower right end of the filter box, and a sealing gasket is provided in the middle of the upper part of the fixed cover plate. After the fixed cover plate is flipped, it is locked at the lower end of the filter box, and the sealing gasket is attached between the fixed cover plate and the filter box.

Detailed Implementation

[0031] 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.

[0032] Please see Figures 1-7 The present invention provides the following technical solution:

[0033] To address the problems in existing technologies where the inner wall of the pipe is in direct contact with the mud, resulting in severe wear during long-term use, and the lack of a mud filtration component during mud intake, which easily causes mud blockage in the pipe and even damages the mud pump, affecting its service life, this solution provides the following technical solution: a multi-port suction pipeline tooling for a mud pump, comprising a main pipe 1, a first flange 2, branch pipes 3, and a second flange 4. Branch pipes 3 are evenly spaced on the front side of the main pipe 1, and a filter component is installed on the front side of the branch pipes 3. The branch pipes 3 are connected to an external mud source through the filter component. The filter component includes a filter box 6, a fixed cover plate 9 that flips at the lower end of the filter box 6, and a filter screen 14 inserted into the filter box 6. The filter screen 14 has a detachable structure in the filter box 6.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the main pipe 1 is welded with a first flange 2 at the top and both sides, the branch pipe 3 is welded with a second flange 4 at the front, the filter box 6 is provided with a third flange 7 at the rear, and the filter box 6 is provided with a fourth flange 8 at the front. The fourth flange 8 is connected to the external mud source equipment. The third flange 7 and the second flange 4 are mutually threaded and limited by bolts and nuts to connect the filter box 6 and the branch pipe 3. At the same time, a sealing ring 17 is provided between the third flange 7 and the second flange 4 to improve the sealing of the connection. In addition, each branch pipe 3 is provided with an independent control valve at the connection point with the mud source to control the opening and closing and flow of the corresponding branch pipe 3, which facilitates multi-source feeding and large flow transportation. The inner sides of the branch pipe 3 and the main pipe 1 are coated with an anti-corrosion and wear-resistant layer 5. The anti-corrosion and wear-resistant layer 5 is made of ceramic or high-chromium cast iron material to improve the wear resistance of the pipe and thus extend the service life of the pipe.

[0035] A filter screen 14 is installed in the filter box 6. The filter screen 14 filters the incoming mud, making the mud entering the mud pump more uniform and providing some protection for the mud pump. Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, after use, the mounting cap 13, which is threaded onto the outer surface of the mounting rod 12, can be rotated to detach the mounting cap 13 from the mounting rod 12, thereby loosening the limit between the fixed cover plate 9 and the filter box 6. At the same time, a sealing gasket 10 is fitted between the fixed cover plate 9 and the lower end of the filter box 6 to prevent leakage. Then, the fixed cover plate 9 is flipped downwards and rotated at the right end of the filter box 6, causing the mounting rod 12 to move out of the mounting groove 11. Simultaneously, the fixed cover plate 9 drives the lower limit side plate 16 to detach from the filter screen 14, loosening the squeezing limit on the filter screen 14. Then, the filter screen 14 is pulled downwards, and the upper end of the filter screen 14 detaches from the upper limit side plate 15, allowing the filter screen 14 to be removed from the filter box 6. This facilitates the disassembly, cleaning, or replacement of the filter screen 14, preventing the filter screen 14 from being clogged by mud during long-term use.

[0036] 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.
