Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and in particular relates to a drum spiral feed cavitation water jet debris cleaning device. Background Technology

[0002] Metal cutting chips are an inevitable byproduct of machining processes such as turning, milling, and drilling. In casting, machining, and many other machinery industries, the amount of metal chips generated after processing accounts for more than 30% of the total raw material output. These chips have enormous potential for recycling and have become the second largest source of metal production after mining and smelting. Besides steel and iron, the recycling value of chips from precious and heavy metals is even higher.

[0003] However, the difficulty in recycling and low recycling rate of cutting fluid scrap due to insufficient cleaning is particularly serious. The core obstacle lies in the complex contaminants formed by the adhesion of cutting fluid and impurities such as metal oxide deposits generated during machining, which severely restrict the efficiency of subsequent resource recovery. The main harms are as follows:

[0004] 1. Unremoved coolant and oil will cause violent gasification during smelting, leading to an increase in the generation rate of slag and waste products, and potentially causing an explosion.

[0005] 2. Some of the debris that was not cleaned in time was also classified as hazardous solid waste by the state. The cost of disposing of the debris was far higher than the cost of cleaning it, and the chemicals used in the cleaning process would also cause irreversible pollution to the environment.

[0006] 3. The capacity of centralized cleaning is far lower than the chip generation rate of modern machining clusters.

[0007] Currently, the main methods for cleaning debris include centrifugation, extrusion, chemical cleaning, and ultrasonic cleaning. Centrifugation and extrusion are effective at removing impurities, but their equipment is expensive and they are difficult to completely remove all impurities. Chemical cleaning is costly and time-consuming, and there is a risk of air and water pollution due to improper operation; moreover, the solid residues after treatment are usually classified as hazardous waste. Ultrasonic cleaning uses cavitation to remove contaminants; however, it is less effective at treating thick layers of oil or stubborn stains.

[0008] Therefore, there is an urgent need for a new cleaning device to achieve deep cleaning of metal scrap in batches. Summary of the Invention

During operation, the power structure drives the spiral drum mechanism, which is loaded with metal scrap, to rotate. The high-pressure water pump provides high-pressure water to the cavitation water jet nozzle, and the cavitation water jet nozzle sprays out a cavitation water jet through the mesh to clean the metal scrap in the drum body.

[0017] Preferably, it also includes a water circulation mechanism connected to the water tank to achieve filtration, cleaning, and automatic circulation of the cleaning liquid in the water tank.

[0018] Preferably, the water tank includes a water tank body and an opening and closing cover. The opening and closing cover is disposed on the top of the front side of the water tank body. The opening and closing cover is hinged to the water tank body and can be flipped upward to open.

[0040] To make the objectives, features, and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described below are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, the same or similar reference numerals may be used in the drawings to refer to the same or similar elements in different embodiments, and descriptions of the same or similar elements in different embodiments, as well as descriptions of prior art elements, features, effects, etc., may be omitted.

[0041] Reference Figures 1-7 This invention provides a drum-type spiral feed cavitation water jet debris cleaning device.

[0042] like Figure 1 As shown, the drum-type spiral feed cavitation water jet cleaning device includes a spiral drum mechanism 2, a cavitation water jet cleaning mechanism 3, a water tank 1, and a high-pressure water pump 4. The spiral drum mechanism 2 is cylindrical in shape and is rotatably installed in the water tank 1 and partially submerged in the cleaning liquid 8 within the water tank 1. The spiral drum mechanism 2 includes at least a drum body 2-1. Multiple mesh holes are evenly distributed on the cylinder wall of the drum body 2-1. The drum body 2-1 is provided with an inlet 2-4 and an outlet 2-5. The cavitation water jet cleaning mechanism 3 is located inside the water tank 1 and is positioned relative to the drum. The cylinder wall of the main body 2-1 is provided with a cavitation water jet cleaning mechanism 3, which includes at least a cavitation water jet nozzle 3-4. The cavitation water jet nozzle 3-4 is connected to a high-pressure water pump 4 and is immersed in the cleaning liquid 8 in the water tank 1. The water tank 1 is provided with a power structure 1-3, which is used to drive the spiral drum mechanism 2 to rotate. During operation, the power structure 1-3 drives the spiral drum mechanism 2, which is loaded with metal scrap 6, to rotate. The high-pressure water pump 4 provides high-pressure water to the cavitation water jet nozzle 3-4, and the cavitation water jet nozzle 3-4 sprays out a cavitation water jet 7 to clean the metal scrap 6 in the main body 2-1 through the mesh.

[0043] Specifically, under the high pressure of the high-pressure water pump 4, the water flow generates a cavitation effect through the cavitation water jet nozzles 3-4 to form a cavitation water jet 7, thereby generating a large number of cavitation bubbles. When the cavitation bubbles collapse, they generate high-energy impacts that wash away debris.

[0044] The working principle of cavitation water jet 7 is that during the cavitation process, a large number of cavitation bubbles are generated, grow, and collapse. When the cavitation bubbles collapse upon contact with the material surface, a portion of the fluid generates micro-jet streams with high temperature, high pressure, and extremely high velocity, thus generating a huge impact force to clean the target. When using cavitation water jet 7 for cleaning, the huge impact force can remove oxide deposits on the surface of the debris. For oily substances, the polarity of water decreases with increasing temperature. The weak polarity exhibited by the local high temperature increases its solubility with non-polar substances such as oils, thereby effectively cleaning oily substances in the debris. Cavitation water jet 7 cleaning mainly relies on the energy generated by the collapse of the bubble cluster, so it can completely clean large quantities of debris. The advantages of cavitation water jet 7 cleaning are that it does not harm the environment or the health of workers, saves energy, has high cleaning efficiency, and is easy to mechanize and automate.

[0045] In existing technologies, ultrasound can also produce cavitation effects, and ultrasonic cleaning is also used for cleaning debris, but its cavitation effect is limited, far lower than that produced by water jets; the cleaning efficiency and cleaning effect are also limited.

[0046] Specifically, the mesh holes provided through the cylinder wall of the drum body 2-1 allow the cavitation water jet nozzles 3-4 to spray cavitation water jets 7 through the mesh holes to clean the metal shavings 6 in the drum body 2-1, while simultaneously discharging the cleaned impurities.

[0047] In some embodiments, the spiral drum mechanism 2 further includes a spiral support column 2-3 and a spiral blade 2-2. The spiral support column 2-3 is coaxially fixed inside the drum body 2-1, and the spiral blade 2-2 is fixed to the outer wall of the spiral support column 2-3 and is disposed in close contact with the inner wall of the drum body 2-1. When the drum body 2-1 rotates, the spiral blade 2-2 rotates synchronously, driving the metal scrap 6 in the drum body 2-1 to be conveyed axially from the feed port 2-4 to the discharge port 2-5.

[0048] In some embodiments, the inlet 2-4 and the outlet 2-5 are both cylindrical and coaxially fixed to both ends of the roller body 2-1. The two ends of the water tank 1 are respectively provided with roller support seats 1-5. The roller support seats 1-5 are cylindrical and match the inlet 2-4 and the outlet 2-5. The inlet 2-4 and the outlet 2-5 are respectively disposed in the roller support seats 1-5 and can rotate along the roller support seats 1-5.

[0049] In some embodiments, the power structure 1-3 is disposed at one end of the water tank 1 and connected to the roller support seat 1-5 to drive the roller body 2-1 to rotate.

[0050] Specifically, the power structure 1-3 includes a motor, a reducer, and a transmission structure. The transmission structure can be a gear or belt drive. The transmission structure is connected to the feed inlet 2-4 to drive the drum body 2-1 to rotate.

[0051] In some embodiments, the cavitation water jet cleaning mechanism 3 is in two sets; the two sets of cavitation water jet cleaning mechanisms 3 are symmetrically arranged on both sides of the drum body 2-1, and the cavitation water jet nozzles 3-4 of the two sets of cavitation water jet cleaning mechanisms 3 are arranged relative to the drum wall of the drum body 2-1.

[0052] In some embodiments, the cavitation water jet cleaning mechanism 3 further includes a support platform 3-2, a jet pipeline integration module 3-1, and a nozzle bracket 3-3. There are multiple cavitation water jet nozzles 3-4, which are fixed to the support platform 3-2 at intervals along the axial direction of the roller body 2-1 by multiple nozzle brackets 3-3. The jet pipeline integration module 3-1 is installed on the support platform 3-2 and connects the cavitation water jet nozzles 3-4 and the high-pressure water pump 4.

[0053] Specifically, the two sets of symmetrically arranged cavitation water jet cleaning mechanisms 3 have multiple cavitation water jet nozzles 3-4 spaced apart along the axial direction of the drum body 2-1. When the drum body 2-1 rotates and drives the metal scrap 6 to move, the multiple cavitation water jet nozzles 3-4 perform full-coverage overlapping cleaning of the scrap along the axial direction of the drum body 2-1. The jet pipeline integration module 3-1 integrates the liquid pipelines of each cavitation water jet nozzle 3-4 and can adjust the water pressure of the cavitation water jet nozzle 3-4. The lead-out end of the jet pipeline integration module 3-1 is connected to the cavitation water jet nozzle 3-4, and the inlet end is connected to the external high-pressure water pump 4, which together form the hydraulic circuit of the cavitation water jet.

[0054] Specifically, the cavitation water jet nozzles 3-4 are set at a certain angle downwards to the bottom surface of the water tank 1. The ends of the cavitation water jet nozzles 3-4 are immersed in the cleaning liquid 8. The cavitation water jet 7 of each cavitation water jet nozzle 3-4 is ejected in a direction perpendicular to the feeding direction of the debris. When the debris is fed, it will pass through each cavitation water jet nozzle 3-4 in sequence to achieve the effect of overlapping cleaning.

[0055] In some embodiments, a water circulation mechanism 5 is also included, which is connected to the water tank 1 to achieve filtration, cleaning and automatic circulation of the cleaning liquid 8 in the water tank 1.

[0056] In some embodiments, the water tank 1 includes a water tank body 1-2 and an opening and closing cover 1-1. The opening and closing cover 1-1 is disposed on the top of the front side of the water tank body 1-2, and the opening and closing cover 1-1 is hinged to the water tank body 1-2 and can be flipped upward to open.

[0057] Specifically, the cover 1-1 can be closed after the drum body 2-1 is installed to prevent the cleaning liquid 8 from splashing during cleaning and to isolate the noise generated during cleaning.

[0058] In some embodiments, a water inlet 1-4 is provided at the bottom front side of the water tank body 1-2, a lower drain outlet 1-7 is provided at the bottom rear side of the water tank body 1-2, and an upper drain outlet 1-6 is provided in the middle of the water tank body 1-2. There are multiple upper drain outlets 1-6, and the multiple upper drain outlets 1-6 are located on the same horizontal line. The upper drain outlets 1-6 are used to control the liquid level of the cleaning liquid 8 in the water tank 1.

[0059] Specifically, the water inlets 1-4 are two located on the front bottom of the water tank body 1-2 near both ends; the drain outlets 1-7 are two located on the rear bottom of the water tank body 1-2 near both ends.

[0060] Specifically, the water circulation mechanism 5 is installed near the water tank 1. The outlet of the water circulation mechanism 5 is connected to the inlet 1-4 of the water tank body 1-2, and the return outlet of the water circulation mechanism 5 is connected to the lower drain outlet 1-7 and the upper drain outlet 1-6 of the water tank body 1-2. The water circulation mechanism 5 settles impurities and filters sewage, and then re-enters the filtered sewage into the water tank 1 to realize the circulation of water during the cleaning process. The water circulation mechanism 5 adopts existing technology and only needs to meet the function of settling impurities and filtering sewage. The structure of the water circulation mechanism 5 is not limited.

[0061] Specifically, during the cleaning of metal scrap, the liquid level is increased to the upper drain outlet 1-6 through the water inlet 1-4. The upper drain outlet 1-6 controls the liquid level of the cleaning liquid 8 in the water tank 1, thereby controlling the distance between the metal scrap and the liquid surface. Since the washed-out oily substances will float on the liquid surface, the oil floating on the water surface can be discharged in time through the upper drain outlet 1-6 under the flow of circulating water. The metal scrap is completely submerged below the liquid level in the drum body 2-1. At the same time, the cavitation water jet nozzle 3-4 is immersed below the liquid level and sprays cavitation water jet 7 to create a cavitation effect, thereby cleaning the metal scrap 6. During the cleaning process, the cleaning liquid 8 inside the water tank 1 is circulated regularly to ensure the cleanliness of the liquid.

[0062] Specifically, the high-pressure water pump 4 is installed near the water tank 1 to provide high water pressure for the cavitation water jet nozzles 3-4.

[0063] Specifically, the water tank 1 has an openable front panel. After cleaning the debris for a certain period of time, the solid impurities inside the water tank 1 can be cleaned by opening the front panel, which facilitates the cleaning of the inside of the water tank 1.

[0064] In some embodiments, a fixing frame 1-8 is provided below the water tank 1, and the water tank 1 is installed on the fixing frame 1-8.

[0065] The working process of the drum spiral feed cavitation water jet debris cleaning device according to an embodiment of the present invention is as follows:

[0066] Material conveying: The material is conveyed into the feed inlet 2-4 of the screw roller mechanism 2;

[0067] Feeding and Immersion: Under the rotation of the drum body 2-1 of the spiral drum mechanism 2, the spiral blades 2-2 inside the drum body 2-1 push the chip forward, while the chip is immersed in the cleaning liquid 8 of the water tank 1.

[0068] Overlapping cleaning: During the advance of the debris, the cavitation water jet nozzles 3-4 of the cavitation water jet cleaning mechanism 3 clean the debris in sequence. Since the debris passes through the cleaning range of each cavitation water jet nozzle 3-4 in sequence, the effect of overlapping cleaning is achieved.

[0069] Material discharge: With the rotation of the drum body 2-1, the drum body 2-1 can continuously feed and discharge a large amount of material. After cleaning is completed in the drum body 2-1, the material is pushed out of the discharge port 2-5 by the spiral blades 2-2, thus completing the cleaning and transportation of the material.

[0070] In summary, the drum-type spiral feed cavitation water jet debris cleaning device of this invention uses a high-pressure water pump 4 and cavitation water jet nozzles 3-4 to generate cavitation water jets 7 for deep cleaning of the debris surface, significantly improving the cleaning effect and improving the utilization rate and yield of the debris. The spiral drum conveys the debris, resulting in a compact overall structure that is easy to install and has a low overall manufacturing cost. Under the action of the spiral drum, the debris is tumbled in real time during feeding, and in conjunction with the cavitation water jet cleaning mechanism 3 and its multiple cavitation water jet nozzles 3-4, it achieves full-coverage overlapping cleaning of the debris, increasing the effective area of ​​the cavitation water jets 7, enabling batch cleaning of debris in a short time, and significantly improving the cleaning efficiency.

[0071] Furthermore, under the action of the timed water circulation mechanism 5, the water tank 1 can promptly remove the washed oil and cutting fluid, and the upper drain outlet 1-6 can promptly discharge the oil on the surface of the cleaning liquid 8, ensuring that the debris will not be secondary contaminated after cleaning; the lower drain outlet 1-7 at the bottom of the water tank 1 can discharge the waste liquid in the water tank 1 more efficiently, which is beneficial to the cleaning of the inside of the water tank 1 after cavitation water jet cleaning.

[0072] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the invention, even when only a single embodiment is described with respect to a particular feature. The feature examples provided in this disclosure are intended to be illustrative and not limiting, unless otherwise stated.
