Description

Technical Field

[0001] The present application relates to the technical field of mechanical cleaning equipment, and in particular to a single-station double-liquid drum type cleaning machine. Background Art

[0002] Rotating parts such as bearing steel balls are widely used in modern industry, especially in the field of mechanical manufacturing. In order to ensure their performance and life, the parts need to be strictly cleaned during the production process. Traditional cleaning technology mainly relies on immersion and multiple transfers. Although this process can meet basic cleaning needs, it is inefficient and difficult to adapt to the requirements of modern industry for high-efficiency and high-quality production. With the continuous growth of market demand, improving cleaning efficiency has become an important issue that the industry needs to solve urgently.

[0003] At present, the commonly used solutions for cleaning rotating parts such as bearing steel balls include immersion cleaning, spray cleaning, and ultrasonic cleaning. Immersion cleaning is to place the parts in the cleaning liquid for a period of time, using the liquid to dissolve or wash away surface impurities; spray cleaning is to directly act on the surface of the parts through high-pressure water flow to achieve a cleaning effect; ultrasonic cleaning uses the cavitation effect generated by high-frequency vibration to remove tiny impurities. In addition, there are some combined cleaning equipment, which usually combines multiple cleaning methods to improve the cleaning effect. However, these methods generally have the problems of cumbersome operation and long time consumption.

[0004] The main drawback of the above cleaning methods is that most of them require multiple transfers of parts, and the cleaning process cannot be operated continuously, resulting in low overall cleaning efficiency. Especially when processing large quantities of parts, this inefficient cleaning method will significantly increase production costs and reduce production cycles. Therefore, how to design a device that can reduce the number of part transfers and improve cleaning efficiency has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to solve the above problems, the present application provides a single-station double-liquid drum cleaning machine.

[0006] A single-station double-liquid drum cleaning machine includes a drum, a water circulation device and a drying device. The inner surface of the drum is provided with spiral blades, and the spiral blades adopt a segmented design. The drum cleans the parts and discharges the cleaned parts by rotation. The water circulation device provides a continuous water flow for the cleaning process, and the drying device is used to dry the cleaned parts.

[0007] Preferably, the water circulation device includes a water receiving trough located below the drum, a water leakage hole is opened on the drum, the water receiving trough is funnel-shaped and has two valves at the bottom, two cleaning boxes are arranged below the water receiving trough, and the two valves are connected to the two cleaning boxes respectively.

[0008] By adopting the above technical solution, the water receiving tank is designed in a funnel shape, which can effectively collect the wastewater generated during the cleaning process, and the two valves arranged at the bottom respectively direct the wastewater to two cleaning boxes, realizing the split treatment of the wastewater. This design not only improves the efficiency of wastewater treatment, but also avoids the blockage problem that may be caused by a single flow path, thus enhancing the operating stability of the entire cleaning machine. Preferably, a slope plate is inclinedly arranged in the cleaning box, one end of the slope plate receives the water flow from the water receiving tank, and a magnetic roller is arranged at the end of the other end. A scraper for scraping the magnetic roller is also arranged in the cleaning box.

[0009] By adopting the above technical solution, the slope plate inclinedly arranged in the cleaning box can effectively guide the water flow, enabling the impurities in the water to smoothly flow towards the magnetic roller, thereby improving the collection efficiency of the impurities. The setting of the magnetic roller can adsorb the iron impurities in the water, further enhancing the purity of the cleaning water. The scraper is used to scrape the magnetic roller to prevent excessive impurities from being adsorbed on the surface of the magnetic roller and affecting the adsorption effect, ensuring the continuous and efficient operation of the magnetic roller. Preferably, a water tank is arranged adjacent to each of the two cleaning boxes, and the water tank is connected to the cleaning box through a pipeline.

[0010] By adopting the above technical solution, the recycling of the cleaning water is realized. The combined design of the cleaning box and the water tank enables the preliminarily filtered cleaning water to be stored in the water tank and conveyed to the spray pipe through the pipeline, providing a continuous water flow supply for cleaning the parts in the drum. This not only reduces the waste of water resources, but also simplifies the water supply system of the cleaning device and improves the cleaning efficiency.

[0011] Preferably, the drying device includes a heating box, a blower, a circulation pipe and a pressurizing box. A heating element is arranged in the heating box, and the blower forcibly pumps the heated hot air out of the heating box. The heating box is connected to the pressurizing box through a pipeline, and the pressurizing box is connected to the spray pipe through a pipeline.

[0012] By adopting the above technical solution, the drying device can efficiently dry the parts in the drum. The heating element in the heating box is used to heat the air and provide high-temperature hot air to ensure the temperature requirement during the drying process. The blower forcibly pumps out the heated hot air, improving the efficiency and uniformity of hot air delivery and reducing the drying time. The heating box is connected to the pressurizing box through a pipeline, and the pressurizing box further pressurizes the hot air to enhance the spraying force of the hot air, enabling the hot air to more effectively cover the surface of the parts and improving the drying effect. The pressurizing box is connected to the spray pipe through a pipeline, and the pressurized hot air is accurately conveyed to the inside of the drum to achieve comprehensive drying of the parts and avoid residual moisture.

[0013] Preferably, the circulation pipe is arranged above the inside of the drum. Air holes are formed on the surface of the circulation pipe. The circulation pipe is connected to the heating box through a pipeline. The circulation pipe uses the negative pressure formed in the heating box to extract air from the inside of the drum.

[0014] By adopting the above technical solution, the circulation pipe is arranged above the inside of the drum and is provided with air holes, which can effectively use the negative pressure formed in the heating box to extract air from the inside of the drum. This design not only promotes the rapid discharge of air in the drum, but also accelerates the evaporation of water vapor in the drum, thereby improving the drying efficiency. At the same time, since the circulation pipe is connected to the heating box, the formed negative pressure helps the hot air to be evenly distributed in the drum, further improving the drying effect and energy utilization efficiency.

[0015] Preferably, one end of the spray pipe extending out of the drum is fixedly connected with a connecting branch pipe. The two ends of the connecting branch pipe are respectively connected to the two water tanks through pipelines. A rotating shaft is arranged inside the connecting branch pipe. Scroll fans are respectively arranged at the two ends of the rotating shaft close to the connecting branch pipe.

[0016] By adopting the above technical solution, the two ends of the connecting branch pipe are respectively connected to the two water tanks, so that the spray pipe can receive the water flow supply from the two water tanks at the same time, thereby improving the water flow stability during the cleaning process. The rotating shaft arranged inside the connecting branch pipe and the scroll fans at both ends of the rotating shaft can drive the scroll fans to rotate when the water flow passes through, and then generate a certain fluid stirring effect, making the water flow more evenly distributed in the spray pipe, improving the cleaning efficiency and cleaning effect.

[0017] Preferably, the connecting branch pipe is communicated with a pressurizing box. A pressurizing cylinder is rotatably arranged in the pressurizing box through a rotating shaft. Driven teeth are arranged on the pressurizing cylinder. A driving gear meshing with the driven teeth is arranged on the rotating shaft.

[0018] By adopting the above technical solution, the connecting branch pipe is communicated with the pressurizing box, so that the water flow can enter the pressurizing box, and the kinetic energy of the water flow is used to drive the rotating shaft to rotate. The pressurizing cylinder in the pressurizing box is meshed with the driving gear on the rotating shaft through the driven teeth to realize the synchronous rotation of the pressurizing cylinder. This design can effectively improve the efficiency of the pressurizing process, and at the same time use the mechanical transmission structure to convert the kinetic energy of the water flow into pressurizing power, reducing the additional energy consumption and improving the overall energy-saving and environmental protection performance of the equipment.

[0019] Preferably, the cross section of the pressurizing cylinder is fan-shaped. The surface of the pressurizing cylinder is abutted against the inner wall of the pressurizing box through a sealing strip. A partition plate is arranged at the bottom of the pressurizing cylinder. The top of the partition plate holds up the rotating shaft of the pressurizing cylinder. The partition plate and the pressurizing cylinder divide the inside of the pressurizing box into a pressurizing chamber and an extrusion chamber. The pressurizing chamber and the extrusion chamber are respectively connected to the heating box through pipelines. A one-way valve communicating the pressurizing chamber and the extrusion chamber is arranged on the partition plate.

[0020] By adopting the above technical solution, the cross-section of the pressure cylinder is designed in a fan shape, which can effectively increase the contact area with the inner wall of the pressure box, and achieve more efficient gas compression and transmission during rotation. The setting of the sealing strip further improves the sealing performance between the pressure cylinder and the inner wall of the pressure box, avoids gas leakage, and ensures the stability and reliability of the pressurization process. The partition plate divides the interior of the pressure box into a pressurization chamber and an extrusion chamber. In combination with the use of a one-way valve, it realizes the directional flow of gas between different chambers, avoids gas backflow, and thus significantly improves the pressurization efficiency of hot gas and the drying effect.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. The drum realizes the cleaning and discharging of parts through rotation. Combined with the continuous water flow provided by the water circulation device, it can effectively reduce the multiple transfers of parts and improve the cleaning efficiency; 2. The drying device works in cooperation with the drum, uses hot gas to dry the parts, ensures the rapid drying of the parts after cleaning, and further improves the overall operation efficiency; 3. The overall device integrates the functions of cleaning and drying, simplifies the operation process, and meets the requirements of modern industry for high-efficiency and high-quality production.

Detailed Description of the Embodiment

[0024] The following further describes the present application in detail with reference to the drawings.

[0025] In the description of the invention, it should be understood that for the orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc., it is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0026] The embodiment of the present application discloses a single-station double-fluid drum-type cleaning machine. Refer to Figure 1 and Figure 3 , which includes a housing 10, a drum 31, a water circulation device, and a drying device. The inner surface of the drum 31 is provided with a spiral blade 312. The spiral blade 312 adopts a segmented design. In the embodiment of the present application, the spiral blade 312 is in two segments and is disconnected at a position close to the middle of the drum 31, forming a region with a larger volume relative to other parts inside the drum 31 at the middle of the drum 31. The drum 31 rotates to clean the parts and discharge the cleaned parts. For example, when the drum 31 rotates in one direction, the parts will always be inside the drum 31 and tumble, and this process corresponds to the cleaning process of the drum 31. In addition, if the drum 31 is rotated in the direction opposite to the cleaning direction, the parts inside the drum 31 will be discharged, and this process is applicable to the blanking of the cleaned parts.

[0027] Refer to Figure 1 , Figure 2 and Figure 3, the water circulation device provides continuous water flow for the cleaning process, and the drying device is used to dry the parts after cleaning. Therefore, this application also has the function of circulating water flow and recycling hot air to meet the current requirements of energy conservation and environmental protection. Specifically, for the water circulation, a spray pipe 32 is arranged inside the drum 31, and a jet pipe 34 is arranged inside the spray pipe 32. The spray pipe 32 and the jet pipe 34 respectively receive the water supply from the water circulation device and the air supply from the drying device. A number of water spray holes 33 are formed on the spray pipe 32. In order to improve the cleaning efficiency, the water spray holes 33 can also be set as high-pressure nozzles. The water spray holes 33 evenly spray the water flow inside the drum 31 to facilitate the flushing of the parts. In addition, in order to improve the water-saving performance of the equipment, the water circulation device includes a water receiving tank 11 located below the drum 31, and the water receiving tank 11 is used to recover the cleaning water. Leakage holes 311 are formed on the drum 31. The leakage holes 311 only allow water flow to pass through and do not allow parts to pass through. The leakage holes 311 are arranged circumferentially around the drum 31 and are directly opposite to the water receiving tank 11, facilitating the water flow to fall into the water receiving tank 11 through the leakage holes 311. The water receiving tank 11 is in a funnel shape and is provided with two valves at the bottom. Both valves are set as electric control valves and independently control their opening and closing. Two cleaning boxes 12 are arranged below the water receiving tank 11, and the two valves are respectively communicated with the two cleaning boxes 12. A water tank 13 is arranged adjacent to each of the two cleaning boxes 12, and the water tank 13 is communicated with the cleaning box 12 through a pipeline, enabling the water in the cleaning box 12 to flow into the water tank 13. The water tank 13 is used to supply water to the spray pipe 32, and a water pump is used to pump the water flow in the water tank 13 back into the spray pipe 32 for spraying and cleaning again, thereby realizing the water circulation process. By providing two cleaning boxes 12 and the water tanks 13 respectively and independently communicated with the two cleaning boxes 12, the water flow flowing out of the water receiving tank 11 can be diverted to different cleaning boxes 12 and water tanks 13 through the two valves.

[0028] Refer to Figure 5 , a slope plate 121 is inclinedly arranged inside the cleaning box 12. One end of the slope plate 121 receives the water flow from the water receiving tank 11 and a magnetic roller 122 is arranged at the end of the other end. A scraper 123 for scraping the magnetic roller 122 is also arranged inside the cleaning box 12. The magnetic roller 122 is driven by a motor to rotate. Since the parts are metal products, during the process of rotating and cleaning inside the drum 31, the burrs on the surface will inevitably be cleaned and dropped. When the cleaning water passes through the magnetic roller 122, the magnetic roller 122 will adsorb the magnetic metal in the water flow to avoid damage to the parts caused by fine metal debris. The scraper 123 contacts the top of the magnetic roller 122, so it forms an angle with respect to the side wall of the cleaning box 12. The scraped metal debris will be centrally collected at the top of the scraper 123. A reserved opening is formed at the position of the cleaning box 12 corresponding to the top of the scraper 123, and the reserved hole facilitates the regular cleaning of the metal debris.

[0029] Refer to Figure 1, Figure 3 and Figure 4 , for the air circulation, the drying device includes a heating box 21, a blower 212, a circulation pipe 214, and a pressurizing box 213. A heating element 211 is arranged in the heating box 21, and the heating element 211 raises the temperature of the air in the heating box 21. The blower 212 forcibly pumps the heated hot air out of the heating box 21. The heating box 21 is connected to the pressurizing box 213 through a pipeline, and the pressurizing box 213 is connected to a jet pipe 34 through a pipeline. The pressurizing box 213 is used to increase the pressure of the hot air, so that when the hot air is ejected by the jet nozzle 35, it can have a higher pressure to carry more moisture, improving the process of drying the parts. One end of the spray pipe 32 extending out of the drum 31 is fixedly connected to a connecting branch pipe 4. Both ends of the connecting branch pipe 4 are respectively connected to two water tanks 13 through pipelines. A rotating shaft 41 is arranged in the connecting branch pipe 4, and vortex fans 42 are respectively arranged at two ends of the rotating shaft 41 close to the connecting branch pipe 4. The connecting branch pipe 4 is communicated with the pressurizing box 213. A pressurizing cylinder 44 is rotatably arranged in the pressurizing box 213 through the rotating shaft 41. The communication part between the connecting branch pipe 4 and the pressurizing box 213 is sealed by the pressurizing cylinder 44. The drum 31 is set as a lightweight plastic hollow cylinder, and its surface and interior are sealed and airtight. A driven gear 45 is arranged on the pressurizing cylinder 44, and a driving gear 43 meshing with the driven gear 45 is arranged on the rotating shaft 41. The water flow injected into both ends of the connecting branch pipe 4 will drive the vortex fans 42 to rotate. When the vortex fans 42 rotate, they will drive the pressurizing cylinder 44 to rotate along the rotating shaft 41 through the driving gear 43 and the driven gear 45. Since the smaller driving gear 43 drives the larger driven gear 45, the rotation of the pressurizing cylinder 44 will have a higher torque. Since the rotation of the vortex fans 42 is driven by the water flow, the driving gear 43 will also have a higher torque when rotating.

[0030] The cross-section of the pressurizing cylinder 44 is fan-shaped. The surface of the pressurizing cylinder 44 abuts against the inner wall of the pressurizing box 213 through a sealing strip. A partition plate 48 is arranged at the bottom of the pressurizing cylinder 44. The top of the partition plate 48 supports the rotating shaft 41 of the pressurizing cylinder 44. The partition plate 48 and the pressurizing cylinder 44 divide the interior of the pressurizing box 213 into a pressurizing chamber 46 and an extrusion chamber 47. Through the arrangement of the pressurizing cylinder 44 and the sealing strip, the pressurizing chamber 46 and the extrusion chamber 47 have a certain airtightness. The pressurizing chamber 46 and the extrusion chamber 47 are respectively connected to the heating box 21 through pipelines. Solenoid valves are arranged at the pipe orifices of the connected pipelines, which is convenient for the operator to control or automatically control the opening and closing moments. A one-way valve 49 communicating the pressurizing chamber 46 and the extrusion chamber 47 is arranged on the partition plate 48. The pressurized hot air is ejected by a plurality of jet nozzles 35 opened on the jet pipe 34, and all the jet nozzles 35 face the bottom of the spray pipe 32 and extend out of the spray pipe 32.

[0031] The circulation pipe 214 is arranged above the interior of the drum 31. Air holes are formed on the surface of the circulation pipe 214. The circulation pipe 214 is connected to the heating box 21 through a pipeline. When the hot air in the heating box 21 is pumped into the pressure box 213 by the blower 212, a negative pressure will be formed inside the heating box 21. The circulation pipe 214 uses the negative pressure formed inside the heating box 21 to extract air from the interior of the drum 31, thereby completing the air circulation process.

[0032] The implementation principle of the embodiment of this application is as follows: A single-station double-fluid drum-type cleaning machine provided by this application adopts a single-station setting. During the cleaning process of parts, there is no need to transfer the parts twice, and the cleaning and drying procedures of the parts can be completed.

[0033] The unwashed parts are introduced into the interior of the drum 31. As the drum 31 rotates, the water circulation device sprays water into the drum synchronously. Since the water circulation device uses two independent water tanks 13 and a cleaning tank 12 and forms two branch circuits, before spraying water, the water circulation can also spray the cleaning liquid. The cleaning liquid is first sprayed. As the drum 31 rotates, some parts will gather in the open area where the spiral blades 312 are disconnected in the middle, so as to facilitate the full mixing of the cleaning liquid and the parts. During the process of spraying the cleaning liquid, the cleaning liquid is always in a circulating flow state. The cleaning liquid will clean the fine surface of the parts and improve the cleaning effect. After using the cleaning liquid, clean water is sprayed through the water tank 13, the water pump and the spray pipe 32 to wash away the cleaning liquid. The processes of flushing with the cleaning liquid and clean water are carried out successively. When recovering the cleaning liquid and clean water, they are drained through two independently controlled valves, so that the circulation of the cleaning liquid and clean water can be realized respectively.

[0034] After the parts are cleaned, drying treatment is required. In the previous process, the cleaning liquid and clean water enter from two directions of the connecting branch pipe 4, so the directions of driving the rotation of the vortex fan 42 are also different, thus enabling the pressure cylinder 44 to rotate in two directions to form a swinging movement trajectory. Through reasonable settings, we make the pressure cylinder 44 swing towards the pressure chamber 46 first and reduce the volume of the pressure chamber 46. Before the pressure cylinder 44 swings towards the pressure chamber 46, the pressure chamber 46 is first filled with hot air by the blower 212, and then as the pressure cylinder 44 swings, the air in the pressure chamber 46 is first pressurized. When the pressure cylinder 44 compresses the volume of the pressure chamber 46 to the lowest, that is, when the cleaning liquid has just been used for cleaning and is about to switch to spraying clean water, the blower 212 fills the extrusion cylinder with hot air. With the supply of clean water, the pressure cylinder 44 rotates towards the extrusion chamber 47, compresses the volume of the extrusion chamber 47, and the air in the extrusion chamber 47 will enter the pressure chamber 46 through the one-way valve 49, rapidly increasing the air pressure in the pressure chamber 46. When the supply of clean water to the inside of the drum 31 stops, it means that the cleaning process of the parts has been completed, and the drying device will start drying the parts. The pressurized hot air in the pressure chamber 46 will be rapidly ejected through the air spray pipe 34 and the air spray nozzle 35. During this process, the drum 31 rolls synchronously, and the parts are dried by the hot air, while the circulating pipe 214 provided at the top of the spray pipe 32 recycles the hot air in the drum 31.

[0035] The setting of the pressure cylinder 44 enables the pressure chamber 46 to have a certain storage capacity for hot air. However, due to the limited volume of the pressure chamber 46 and only one batch of high-pressure hot air can be produced during one supply of the cleaning liquid and clean water, the present application also directly sends the hot air blown by the blower 212 into the drum 31 through a bypass passage to ensure that the cleaning machine completes a complete cleaning procedure.

[0036] The present application also includes other rational designs for the normal operation of the cleaning machine, and these similar designs are all conventional operations in the art, so they should not be regarded as limitations on the present application.

[0037] The above are all the preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
