[0002] In industries such as mining, oil drilling, wastewater treatment, and chemicals, it is often necessary to handle fluids containing complex media such as solid particles and slurry. Traditional fluid transport equipment often encounters challenges when handling these media, such as susceptibility to corrosion, short seal life, and easy clogging, resulting in high operating and maintenance costs and low efficiency. Therefore, there is a need for fluid transport equipment that can efficiently, stably, and safely handle these media. While mud pump technology can meet certain specific application requirements to some extent, it still has some shortcomings. Existing mud pumps are prone to clogging when handling slurry containing particulate matter, requiring frequent shutdowns for cleaning, which significantly reduces the continuous operating capacity of the equipment. Utility Model Content

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] This utility model provides a mud isolation pump, such as Figure 1-2As shown, it includes: a pump body 1, an isolation tank 2 and a one-way valve 3. A water pipe 4 is provided on one side of the isolation tank 2, and a mud pipe 5 is provided on the other side of the isolation tank 2. The end of the water pipe 4 away from the isolation tank 2 is connected to the pump body 1, and the end of the mud pipe 5 away from the isolation tank 2 is connected to the one-way valve 3. A vertical isolation pipe 6 is provided inside the isolation tank 2. The lower end of the isolation pipe 6 is connected to the bottom wall of the isolation tank 2. An isolation float 7 is provided inside the isolation pipe 6. The mud pipe 5 is connected to the lower end of the isolation pipe 6.

[0024] The beneficial technical effects of the above technical solution are as follows: When clean water is added into the isolation pipe 6, after the pump body 1 is started, the internal volume of the pump body 1 changes continuously, allowing the mud to enter the space on the right side of the isolation tank 2 from the inlet of the one-way valve 3. After being pressurized, it is discharged from the outlet of the one-way valve 3. In the working state, the isolation float 7 moves back and forth, which plays a blocking role and prevents large solid particles from entering the pump body 1. The medium in the pump body 1 is clean water, which avoids the blockage of the flow channel in the pump body and avoids the corrosion and abnormal wear of the working parts in the pump body. The blockage of the flow channel is limited to the one-way valve part. The valve box is much easier to clean than the pump body, which improves the continuous working capacity of the mud pump.

[0025] In one embodiment, the pump body 1 includes a hydraulic cylinder 101, a pump housing 102, and a plunger 103. The piston rod of the hydraulic cylinder 101 extends into the pump housing 102 and connects to the reciprocating plunger 103. The pump housing 102 is connected to the end of the water pipe 4 away from the isolation tank 2. The hydraulic cylinder 101 drives the plunger 103 to reciprocate within the pump housing 102, causing the volume within the pump housing 102 to continuously change, thus pressurizing the conveyed slurry. The output end of the pump housing 102 is connected to the water pipe 4 via a flange 8, facilitating the installation and removal of the water pipe 4. The isolation tank 2 has a cover 9 at its top, and the isolation tank 2 and the cover 9 are connected by bolts. The cover 9 has a liquid inlet 10 for adding clean water or cleaning the isolation tank. The bottom of the isolation tank 2 has two drain ports 11 for draining clean water or impurities from the isolation tank.

[0026] In one embodiment, such as Figure 1-2As shown, the one-way valve 3 includes: a valve box 301, which is connected to the mud pipe 5; a mud inlet 302 is provided at the bottom of the valve box 301, which is connected to the mud inlet pipe 303; a mud outlet 304 is provided at the top of the valve box 301, which is connected to the mud outlet pipe 305; a mud inlet valve flange 306 is provided inside the valve box 301 near the mud inlet 302; a mud inlet conical valve seat 307 is provided on the mud inlet valve flange 306; a mud inlet ball valve 308 is provided on the mud inlet conical valve seat 307; a mud outlet valve flange 309 is provided inside the valve box 301 near the mud outlet 304; a mud outlet conical valve seat 310 is provided on the mud outlet valve flange 309; and a mud outlet ball valve 311 is provided on the mud outlet conical valve seat 310. The bottom end of the discharge valve flange 309 is connected to one end of the limiting rod 312, and the other end of the limiting rod 312 faces the slurry inlet ball valve 308. The limiting rod 312 is used to limit the upward limit displacement of the slurry inlet ball valve 308. A baffle 313 is provided above the discharge ball valve 311. The baffle 313 is connected to the inner wall of the valve box 301. The baffle 313 is used to limit the upward limit displacement of the discharge ball valve 311. An outlet 314 is provided on the baffle 313 for slurry discharge.

[0027] The beneficial technical effects of the above technical solution are as follows: The mud enters the space on the right side of the isolation tank 2 through the mud inlet pipe 303, mud inlet port 302, mud inlet conical valve seat 307, valve box 301 and mud pipe 5 in sequence. After being pressurized, it is discharged through the mud pipe 5, valve box 301, mud outlet conical valve seat 310 and outlet 314 to the mud outlet pipe 305 for discharge. The mud flows in one direction to prevent mud backflow and to pressurize the mud. The valve box adopts a multi-valve mode. The shape and weight of each valve body are small, thereby realizing the rapid opening and closing of the valve group, improving the flow capacity, dispersing the impact force formed when a single large valve body is opened and closed, and reducing vibration and noise. The pump body has a large working pressure, so the pressure applied to the ball valve is large. The ball valve can fit tightly against the conical opening. When pressure is applied, the outer surface of the ball can contact the conical opening to form a linear sealing band, which can effectively isolate the particulate slurry, avoid the leakage of pressurized slurry in the sealing chamber, and improve the sealing reliability of the valve body.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
