Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and equipment cleaning technology, and in particular to a cleaning structure for the inner cavity of an air compressor housing. Background Technology

[0002] The air compressor housing internal cavity cleaning structure is a specialized mechanical device or system designed to clean the complex cavities inside the air compressor housing. Its core function is to penetrate deep into the air compressor housing to remove contaminants such as casting residues, oil stains, carbon deposits, scale, and machining debris, ensuring safe operation, good heat dissipation, and extended lifespan of the equipment.

[0003] Because the air compressor housing water channel core has a complex structure, long and narrow channels with various bends, casting sand is easily left on the inner surface after casting. These sand particles are firmly attached and hidden in location, making it difficult to effectively reach and remove them using traditional manual brushing, compressed air blowing, or ordinary rinsing tools. Especially in deep cavities, corners, and blind hole areas, there are extensive cleaning blind spots, resulting in the inner cavity cleanliness failing to meet process requirements. In severe cases, this can affect the air compressor's heat dissipation performance, causing local overheating, oil circuit blockage, or even housing cracking. Existing cleaning methods generally suffer from insufficient cleaning power, nozzles that cannot penetrate deeply, and limited operating methods, making it difficult to achieve efficient removal and thorough cleaning of sand residue.

[0004] To address the aforementioned issues, a cleaning structure for the internal cavity of an air compressor housing that provides effective cleaning is needed. Utility Model Content

[0005] To overcome the shortcomings of manual brushing, compressed air blowing, or ordinary rinsing tools being difficult to effectively reach and clean, this utility model provides a cleaning structure for the internal cavity of an air compressor housing.

[0006] The technical solution of this utility model is: a cleaning structure for the internal cavity of an air compressor housing, including a frame, a water tank, a water outlet pipe, a valve, a partition, a mounting frame, a drain pipe, a sliding plate, an electric push rod, a sliding frame, a waterproof motor, a rotating shaft, a mounting plate, a first nozzle, a connecting pipe, a connecting plate, a hose, and an electric nozzle. A water tank is installed inside the frame, and a water outlet pipe is connected to the front side of the water tank. A valve is installed on the water outlet pipe. A partition is provided inside the water tank. A mounting frame is installed on the top of the frame, and a drain pipe is connected to the right side of the mounting frame, penetrating the frame. The left side of the mounting frame... The system has a sliding plate with an electric push rod installed inside. A sliding frame is slidably connected to the sliding plate. The telescopic end of the electric push rod is connected to the sliding frame. A waterproof motor is installed inside the sliding frame. A rotating shaft is rotatably connected to the right side of the sliding frame. The output shaft of the waterproof motor passes through the sliding frame and is connected to the rotating shaft. Mounting plates are symmetrically installed on the rotating shaft. A first nozzle is installed inside each of the two mounting plates. A connecting pipe connects the two first nozzles. A water storage tank has symmetrically installed connecting plates at the front and back. A flexible hose is installed on each of the two connecting plates. An electric nozzle is installed at the other end of each of the two flexible hoses.

[0007] Furthermore, it also includes a connecting pipe and a filter screen. The connecting pipe is connected to the front side of the water tank, and a filter screen is installed on the connecting pipe.

[0008] Furthermore, it also includes flanges, with flanges installed on the connecting pipes.

[0009] Furthermore, the connecting tube is U-shaped.

[0010] Furthermore, each hose is made of pressure-resistant rubber.

[0011] Furthermore, both the frame and the bottom of the water tank are rotatably connected to multiple casters.

[0012] Furthermore, two cylinders are installed inside the mounting frame.

[0013] The beneficial effects of this utility model are as follows: By setting up an electric push rod, a sliding frame, and a swingable first nozzle combination, the cleaning component can automatically penetrate into the deep water channel of the air compressor housing. During the advancement process, it combines high-pressure water flow to perform multi-angle dynamic cleaning, which significantly improves the cleaning coverage and impact force of complex areas such as corners, blind holes, and narrow channels.

Detailed Implementation

[0021] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0022] Example: Cleaning structure for the internal cavity of an air compressor housing, such as Figures 1-6As shown, the system includes a frame 1, a water tank 2, a water outlet pipe 201, a valve 202, a partition 3, a mounting frame 4, a drain pipe 401, a cylinder 5, a sliding plate 6, an electric push rod 7, a sliding frame 8, a waterproof motor 9, a rotating shaft 10, a mounting plate 11, a first nozzle 12, a connecting pipe 13, a connecting plate 14, a hose 15, an electric nozzle 16, a connecting pipe 17, a filter screen 18, and a flange 19. The frame 1 houses the water tank 2, which stores cleaning water and is divided into a clean water area and a wastewater storage area. This provides a continuous water source for the cleaning process and enables the initial collection and recycling of wastewater. Both the frame 1 and the water tank 2 are rotatably connected to multiple casters at their bottoms. The water outlet pipe 201 is connected to the front side of the water tank 2. A valve 202 is installed on the water pipe 201. The water storage tank 2 has a partition 3 inside, dividing it into two chambers: a clean water area and a wastewater storage area. A mounting frame 4 is installed on the top of the frame 1. A drain pipe 401 is connected to the right side of the mounting frame 4, passing through the frame 1. The lower end of the drain pipe 401 connects to the wastewater storage area, used to drain the wastewater generated after cleaning the air compressor housing. Two cylinders 5 are installed inside the mounting frame 4, and the extension and retraction ends of the two cylinders 5 can abut against the air compressor housing to be cleaned. A sliding plate 6 is slidably connected to the left side of the mounting frame 4. An electric push rod 7 passes through the sliding plate 6, and a sliding frame 8 passes through the sliding plate 6, slidingly mounted on the sliding plate 6. The electric push rod 7... The telescopic end of rod 7 is connected to the sliding frame 8. A waterproof motor 9 is installed on one end of the sliding frame 8 near the mounting frame 4. A rotating shaft 10 is rotatably connected to the side of the sliding frame 8 near the mounting frame 4. The output shaft of the waterproof motor 9 passes through the sliding frame 8 and is connected to the rotating shaft 10. Mounting plates 11 are symmetrically installed on the rotating shaft 10. A first nozzle 12 is installed on each of the two mounting plates 11 for spraying and cleaning the internal water channels of the air compressor housing under high pressure. Fan-shaped, rotating, or jet nozzles can be used to effectively remove sand, oil, and other residues. A connecting pipe 13 connects the two first nozzles 12. A connecting plate 14 is symmetrically installed on the inner wall of the water storage tank 2. A flexible hose 15 is installed on each of the two connecting plates 14. The material of pipe 15 is pressure-resistant rubber, which has good flexibility, pressure resistance and corrosion resistance. The other end of both hoses 15 is equipped with electric nozzles 16. The front side of the water storage tank 2 is connected to a connecting pipe 17. The connecting pipe 17 is U-shaped. The end of the connecting pipe 17 is located in the clean water chamber and is lower than the end of the sewage storage area. It is used to naturally return the upper layer of cleaner liquid in the sewage chamber on the left to the clean water chamber on the right, so as to realize the gravity circulation of the cleaning liquid. The inlet end of the connecting pipe 17 in the sewage storage area is equipped with a filter screen 18 to intercept impurities such as sand, metal fragments, and sludge in the returned sewage, so as to prevent them from entering the clean water area and causing nozzle blockage or water pump damage. The end of the connecting pipe 13 away from the first nozzle 12 is equipped with a flange 19.

[0023] During use, first place the air compressor housing to be cleaned on top of the mounting frame 4 for initial positioning. Then, activate the two cylinders 5 inside the mounting frame 4. The telescopic ends of the cylinders 5 extend synchronously, pushing the air compressor housing against the inner wall of the mounting frame 4, achieving rapid and stable clamping and positioning of the workpiece, preventing it from loosening or shifting due to high-pressure water flow during subsequent cleaning. Before starting the cleaning operation, the operator injects an appropriate amount of clean water into the right cavity of the water storage tank 2 as the cleaning medium. This cavity is separated from the left cavity by an internal partition 3, forming an independent clean water area and a wastewater storage area. During the cleaning process, manual or automatic modes can be selected. When using the manual cleaning mode, the operator holds the... The electric nozzle 16, connected to the end of the hose 15, can rotate or swing under the drive of its own motor to spray water, flexibly rinsing the external surface of the air compressor housing, the flange 19 face, and easily accessible orifice areas. The wastewater after cleaning is guided and discharged through the drain pipe 401 set on the right side of the mounting frame 4, and flows through the frame 1 into the wastewater storage area on the left side of the water storage tank 2 for temporary storage. As the wastewater level gradually rises, the relatively clean liquid on the upper layer flows back to the clean water area on the right side of the water storage tank 2 under the action of gravity through the U-shaped connecting pipe 17 set on the front side, realizing the recycling of the cleaning liquid. The filter screen 18 installed on the connecting pipe 17 can effectively intercept sand particles, metal shavings, sludge, and casting residues in the returned wastewater. Impurities are removed to prevent them from entering the circulating water system and causing nozzle blockage or pump damage, ensuring long-term stable system operation. When automated deep cleaning of the deep-hole water channels inside the air compressor housing is required, the operator first pushes the sliding plate 6 to align the center of the electric push rod 7 with the workpiece to be cleaned, ensuring that the cleaning components are aligned with the inlet. Then, the external high-pressure water source or booster pump is connected to one end of the connecting pipe 13 to ensure unobstructed water supply. The electric push rod 7 is then activated, and its telescopic end pushes the sliding frame 8 smoothly to the right along the sliding plate 6, driving the rotating shaft 10 at the right end of the sliding frame 8 and the two mounting plates 11 installed on it to gradually penetrate into the water channels inside the air compressor housing, achieving precise delivery of the cleaning components. At the same time, the waterproof motor 9 installed inside the sliding frame 8 is activated, and its output shaft... The sliding frame 8 is connected to the rotating shaft 10, driving the rotating shaft 10 and the mounting plate 11 on it to reciprocate (e.g., swing 180 degrees) or rotate continuously. This allows the first nozzle 12 installed in the mounting plate 11 to achieve multi-angle dynamic spraying during the forward movement. Combined with the high-pressure clean water delivered from the connecting pipe 13, it performs all-round cleaning of the inner wall of the waterway, effectively impacting and removing attached oil stains, carbon deposits, and difficult-to-treat casting sand. The two first nozzles 12 are connected by the connecting pipe 13 and can be quickly disassembled and maintained through the flange 19 to ensure system reliability. During the entire cleaning process, the first nozzle 12 advances and rotates while spraying water, forming an integrated operation process of advancement-swing-rinsing, which significantly improves the cleaning coverage and cleanliness of complex inner cavities.After cleaning, the electric push rod 7 retracts, causing the entire cleaning assembly to eject the workpiece. Releasing cylinder 5 allows the workpiece to be removed. Simultaneously, the wastewater storage area on the left can be cleaned periodically or connected to an external sewage system for centralized treatment.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may 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.
