Description

Technical Field

[0001] This utility model belongs to the technical field of water pump processing equipment, and in particular relates to a water pump disassembly device. Background Technology

[0002] As a widely used fluid transport device, water pumps generate a large number of used pumps after their service life ends or they break down. These used pumps typically contain recyclable metals (such as iron, copper, and aluminum), rubber seals, and internal components (such as impellers, shafts, and especially the elastic elements / springs emphasized in the claims). To effectively recycle resources and reduce environmental pollution, efficient and environmentally friendly dismantling of used pumps is a crucial step.

[0003] Currently, the dismantling of used water pumps, especially the separation of core components (such as internal parts that require overcoming elastic elements or snap-fit ​​structures), mainly relies on the following methods:

[0004] Manual disassembly: Workers use simple tools such as hammers, chisels, and wrenches to disassemble the parts by tapping and prying. This method has significant drawbacks:

[0005] Extremely inefficient: Disassembling a single water pump takes too long.

[0006] Significant safety hazards: During forceful striking or prying, metal fragments, springs, and other parts can easily fly at high speed, which can easily cause personal injury to operators (such as cuts or eye injuries). At the same time, the noise generated can also damage workers' hearing.

[0007] Unstable dismantling quality: Relying on worker experience and skills, valuable components (such as copper coils and precision parts) are easily damaged, reducing recycling value.

[0008] High labor intensity: long hours of repetitive, high-intensity physical labor.

[0009] Partial mechanization: Some recycling lines may use simple presses and cutting equipment for overall flattening or cutting. However, this is mainly for whole-body crushing and recycling of metal, and cannot achieve precise disassembly and separation and recycling of internal components (especially elastic components such as springs or internal barrel-shaped components that require special handling as mentioned in the claims). The degree of refined resource utilization is low, and there are also safety and environmental problems such as noise and splashes.

[0010] Existing technologies lack a dedicated device specifically designed for the structural characteristics of water pumps (such as the connection between the outer casing and internal components via snap-fits or elastic elements) that can safely and efficiently separate the main components of a water pump (especially the structure targeted by the disassembly tank in the claims). Existing disassembly equipment is often highly versatile but lacks specificity, failing to effectively address core issues encountered during water pump disassembly, such as the impact of spring preload release, precise part positioning and separation, splash control, and the need for high efficiency. Therefore, there is an urgent need to develop a specialized disassembly device with a reasonable structure, safe operation, high degree of automation, and the ability to effectively handle elastic connection structures (such as springs) in water pumps.

Many specific details are set forth in the following description to provide a thorough understanding of this application.

Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] Please see Figure 1-3 To achieve the above objectives, this embodiment provides a water pump disassembly device, including a conveyor slide rail 1, on which a conveyor component 2 for transporting the water pump is provided.

[0032] In this embodiment, the conveyor rail 1 consists of two parallel C-shaped steel rails laid longitudinally along the workshop, with the rail surface approximately 800 mm above the ground for easy observation by the operator. The inner cavity of the rail serves as both the rolling surface of the pulley and the lubricating oil groove. Detachable mechanical stops are provided at both ends of the rail to prevent the conveyor plate 8 from accidentally being ejected.

[0033] In this embodiment, the conveyor 2 (conveyor plate 8) is located on the slide rail and is a rectangular steel plate, slightly larger in length and width than the base of the water pump to be repaired. Flange-type pulleys are installed at the four corners of the bottom of the steel plate, and the outer edges of the pulleys are coated with rubber to reduce noise. The upper surface of the conveyor plate 8 is milled with a recessed "placement groove", the outline of which matches the shape of the water pump's base, so that the water pump will not shake during transportation; small holes are also opened at the bottom of the groove, so that residual liquid dripping during disassembly can be drained in time, keeping the plate surface clean.

[0034] In this embodiment, the disassembly component 3 spans directly above the slide rail and is supported by a portal frame. An electric screw lifting mechanism is mounted on the top of the frame, and the lifting plate 4 moves up and down along the guide column via four guide sleeves. A circular hole is opened in the center of the lifting plate 4, and a disassembly bucket 5 is concentrically arranged inside the hole. The lower end of the disassembly bucket 5 is a flared opening with a rubber sealing ring, and the upper end is connected to the workshop negative pressure source via a flexible hose. A vertical fixed column 6 is welded to one side of the lifting plate 4. The fixed column 6 is connected to the lifting plate 4 by a spring-moving column assembly: one end of the moving column is screwed into the lifting plate 4, and the other end passes through the fixed column 6 and is limited by a nut. The spring is sleeved around the outer circumference of the moving column, forming a "flexible suspension," which allows the disassembly bucket 5 to swing slightly to align itself when in contact with the water pump, while preventing rigid impact from damaging the pump casing.

[0035] In this embodiment, there is a horizontal support plate 9 below the slide rail, with its four corners welded to the bracket 11 as a whole. The support plate 9 is used to support the fixing column 6, so that the up and down movement of the disassembly bucket 5 is always perpendicular to the slide rail; a diagonal flow fan is also installed on the plate, with the air outlet aligned with the placement slot on the conveyor plate 8, to blow away residual coolant or iron filings after disassembly, ensuring that the next water pump will not slip when it enters.

[0036] In this embodiment, the electrical box 10 is suspended on the right-side support column 11. The electrical box 10 contains a PLC, contactor, negative pressure pump driver, and a 24V switching power supply. The panel has three buttons: "Up / Down / Emergency Stop". The support 11 is a rectangular frame welded from 50×50 square tubing, with lockable casters at the bottom for easy dragging and repositioning.

[0037] In this embodiment, the lifting plate 4 is composed of two symmetrical steel plates, with the joint surface positioned by a trapezoidal stop and then locked with M12 bolts. This design allows the disassembly tank 5 to be pulled out from the side for maintenance without removing the negative pressure pipeline, thus shortening maintenance downtime.

[0038] Workflow

[0039] Loading: The operator hangs the water pump to be disassembled in the placement slot of the conveyor plate 8, and gently pushes the conveyor plate 8. The pulley sends the water pump to the disassembly station along the slide rail. The front end of the station is equipped with a limit switch, which will automatically stop after touching the conveyor plate 8.

[0040] Positioning and Adsorption: When the operator presses the "Lower" button, the lifting plate 4 moves downward as a whole; the flared end of the disassembly tank 5 first contacts the water pump cover, and automatically aligns itself under the flexible action of the spring and the moving column. Then the negative pressure source is activated, and a negative pressure of 0.06–0.08 MPa is formed inside the disassembly tank 5, which firmly adsorbs the water pump cover.

[0041] Separation: The lifting plate 4 continues to descend 3–5 mm, and the pump cover is vertically pulled up and separated from the pump body; if there is rust or jamming, the elastic stroke of the spring can absorb the extra tension to avoid motor overload or pump casing breakage.

[0042] Collection and cleaning: After the top cover is raised to a safe height, the operator moves it horizontally; the blower then starts, blowing the residual liquid and gasket fragments scattered on the conveyor plate 8 toward the chip collection box; the conveyor plate 8 is pushed back to the feeding end by the operator, and the cycle begins.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
