Description

Technical Field

[0001] This utility model relates to the field of fluid machinery technology, and more specifically, to a self-cleaning, vibration-resistant circulating pump. Background Technology

[0002] A tailings dam at a lead-zinc mine in Yunnan Province has accumulated severe waterlogging over the years. It is necessary to address the characteristics of the tailings dam's wastewater, maximizing its resource utilization and improving water recycling rates. Simultaneously, the safety and environmental risks posed by the tailings dam must be resolved. Circulation pumps are commonly used in deep tailings wastewater treatment systems. During operation, when conveying liquids containing heavy metals, COD, ammonia nitrogen, hardness, and other impurities, these impurities accumulate at the inlet, causing unstable flow rates, vibrations, pump tilting, and ultimately, equipment damage. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a self-cleaning, vibration-resistant circulating pump that can solve the equipment damage caused by pump body tilting during operation. Internally, the circulating pump utilizes an annular guide shroud with spiral guide vanes in front of the impeller inlet. This utilizes the fluid's own energy to induce a centrifugal separation effect, guiding impurities to the periphery of the flow channel. This allows relatively clean liquid to preferentially flow towards the impeller's central suction inlet, thus achieving automatic anti-clogging and solving the problem of impeller inlet accumulation when conveying liquids containing heavy metals, COD, ammonia nitrogen, hardness, and other impurities. Externally, auxiliary fixing components are installed to dampen and buffer the pump, thereby improving its operational stability, safety, and service life.

[0004] To solve the above problems, the present invention adopts the following technical solution: a self-cleaning anti-vibration circulating pump, comprising a pump body and an auxiliary fixing assembly, wherein a water inlet pipe is installed at the bottom of the pump body and a motor is installed at the top of the pump body, and a rotating shaft is drivenly connected to the bottom of the motor; a first drain pipe and a second drain pipe are respectively installed on both sides of the pump body, and a valve is installed on one side of the water inlet pipe; the auxiliary fixing assembly is provided in two sets, including a mounting plate disposed on the outside of the pump body, a fixing seat fixedly connected to one side of the mounting plate, an adapter seat fixedly provided to one side of the fixing seat, and a fitting pad fixedly connected to one side of the adapter seat, the fitting pad being connected to the pump body.

[0005] Preferably, the inner side of the fixing seat is provided with a slot, and the side of the fixing seat is threadedly connected with a limiting bolt. A card holder is engaged on one side of the slot, and the outer wall of the card holder is provided with equally spaced threaded grooves. The limiting bolt passes through the fixing seat and is threadedly connected to the threaded grooves on the card holder.

[0006] Preferably, the inner side of the adapter is fitted with an arc-shaped strip, and a limit button is threadedly connected to one side of the adapter.

[0007] Preferably, an impeller is installed inside the pump body, and an annular guide shroud coaxial with the pump body is provided in front of the inlet end of the impeller. The front end of the annular guide shroud is a flared funnel, and the rear end is connected to the inlet flow channel of the pump body. Multiple guide blades arranged in a spiral are evenly distributed circumferentially on the inner ring surface of the annular guide shroud. The annular guide shroud is fixedly connected to the inner wall of the pump body by multiple support ribs evenly distributed circumferentially.

[0008] Preferably, the pump body is composed of an upper pipe and a lower pipe, which are connected by a mounting plate and bolts, and the fitting pad is connected to the middle of the lower pipe.

[0009] Preferably, water meters are installed above the first drain pipe and the second drain pipe, respectively.

[0010] Preferably, both ends of the first drain pipe and the second drain pipe are respectively provided with flanges, and the flanges are connected to the pump body by bolts.

[0011] Preferably, the bonding pad is made of rubber material and is bonded to the outer surface of the pump body.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] (1) In this scheme, the fluid achieves self-cleaning and anti-clogging by using an annular guide shroud and spiral guide blades on its inner ring surface inside the circulating pump, located in front of the impeller inlet. When the pump is working, the liquid flowing through the guide blades is forced to generate a high-speed spiral vortex. Under the action of centrifugal force, impurities such as denser metal particles, COD, ammonia nitrogen, hardness, and fibers are thrown towards the outer ring surface of the annular guide shroud and the inner wall of the pump body, and move forward spirally along the wall surface, eventually entering the impeller flow channel and being pumped out. The relatively clean liquid is concentrated in the central area of ​​the annular guide shroud, forming the main flow towards the impeller inlet. This "impurities flow outward, clean liquid flows inward" mode effectively avoids the direct impact and accumulation of impurities at the root of the impeller blades and the inlet, significantly improving the pump's anti-clogging ability and maintaining the stability of the flow channel.

[0014] (2) This solution enhances the overall stability and reliability of the circulating pump installation by using an auxiliary fixing assembly consisting of a mounting plate, arc-shaped strip, fixed seat, adapter seat, fitting pad, and limiting bolts on the outside of the circulating pump. The rubber fitting pad not only fits tightly against the outer surface of the pump body but also acts as a shock absorber and buffer, reducing vibration transmission during pump operation, lowering noise, and protecting the pump body and connecting pipes. If the pump body tilts, the arc-shaped strip provides stable support, preventing the tilt from widening and causing irreversible damage and loss. Attached Figure Description

The function of the auxiliary fixing component is to enhance the stability of the pump body 1 during installation and to reduce vibration.

[0026] See Figure 1 and Figure 4 The pump body 1 is composed of an upper pipe 101 and a lower pipe 102. The upper pipe 101 and the lower pipe 102 are connected by a mounting plate and bolts. The upper pipe 101 and the lower pipe 102 are used for quick assembly of the pump body 1.

[0027] See Figure 1 and Figure 4 Water meters 6 are installed above drain pipe 1 2 and drain pipe 2 3 respectively. Water meters 6 are used to check the fluid volume.

[0028] See Figure 1 and Figure 5 The motor 4 is connected to a rotating shaft 5 below it. There are two sets of auxiliary fixing components. Each set of auxiliary fixing components has the same structure. The inner side of the fixing seat 11 is provided with a slot, and the side of the fixing seat 11 is threaded with a limit bolt 20. One side of the slot is fitted with a card seat 19. The outer walls of both sides of the card seat 19 are provided with equally spaced threaded grooves. The limit bolt 20 passes through the fixing seat 11 and is threadedly connected to the threaded groove on the card seat 19. The limit bolt 20 and the card seat 19 are used to adjust the lateral distance of the fitting pad 14.

[0029] See Figure 3 An impeller 16 is installed inside the pump body 1. An annular guide shroud 17, coaxial with the pump body 1, is provided in front of the inlet end of the impeller 16. The front end of the annular guide shroud 17 is a flared horn, and the rear end is connected to the inlet of the pump body 1. Multiple guide blades 18 arranged in a spiral are evenly distributed along the circumference on the inner ring surface of the annular guide shroud 17. The annular guide shroud 17 is fixedly connected to the inner wall of the pump body 1 by multiple support ribs evenly distributed along the circumference.

[0030] See Figure 1 and Figure 4Both ends of drain pipe 1 2 and drain pipe 2 3 are respectively equipped with flange 7. The flange 7 is connected to the pump body 1 by bolts. The flange 7 is used for quick disassembly and assembly of the drain pipe.

Start the motor 4, and the rotating shaft 5 drives the impeller 16 to rotate. The liquid enters from the inlet pipe 8 and first flows into the annular guide shroud 17 through the flared opening. The liquid then impacts the spiral guide vanes 18 on the inner ring surface, forcing them to generate a high-speed rotating vortex. Under the action of centrifugal force, impurities such as mud, sand and fibers in the liquid are thrown towards the outer ring surface of the annular guide shroud 17 and the inner wall of the pump body 1, and move forward spirally along the wall surface. The clean liquid in the central area flows towards the center of the impeller 16 inlet, is drawn in by the impeller 16, and discharged from drain pipe 2 and drain pipe 3. Water meter 6 is used to monitor the flow rate. Throughout the process, the self-cleaning anti-clogging structure continuously operates, effectively preventing impurities from clogging the impeller 16 inlet and ensuring the pump's stable and efficient operation.
