Description

Technical Field

[0001] This utility model belongs to the field of cleaning machine technology, and specifically relates to a high-pressure hot water cleaning machine. Background Technology

[0002] Currently, cleaning machines play a crucial role in industrial production and equipment maintenance. They are mainly used to flush and filter contaminants generated or introduced into hydraulic systems during manufacturing, assembly, use, and maintenance. They are also suitable for periodic maintenance and filtration of working fluids. By improving the cleanliness of the fluids, cleaning machines can effectively avoid or reduce malfunctions caused by contamination, thereby ensuring the high performance, high reliability, and long lifespan of hydraulic system equipment. However, existing cleaning machines have many problems in practical applications. On the one hand, most cleaning machines are inconvenient to heat water, which directly leads to poor cleaning results. Even if some cleaning machines can heat clean water, the heating speed is relatively slow, and the water temperature is difficult to control precisely, which seriously affects the efficiency and quality of cleaning operations. To address the aforementioned problems, numerous attempts have been made in related technical fields. For example, Chinese Patent No. CN217369441U discloses a hot water high-pressure cleaner. This utility model includes a base plate, a heating box fixedly mounted on the top of the base plate, a water inlet pipe fixedly mounted on one side of the heating box, a coil fixedly connected to one end of the water inlet pipe, the coil fixedly mounted on the inner wall of the heating box, a water pump fixedly connected to one end of the coil, the water pump fixedly mounted on the top of the base plate, a connecting pipe fixedly connected to the top of the water pump, a temperature sensor mounted on the connecting pipe, and a booster pump fixedly connected to the top of the connecting pipe. The booster pump is fixedly mounted on the other side of the heating box. By using the coil, the time the water spends in the heating box is increased, thereby extending the heating time and enabling rapid heating of clean water. Simultaneously, by driving... The combination of a motor, controller, temperature sensor, double-ended lead screw, moving seat, nut, movable rod, and heating plate allows for the regulation and control of water temperature. Although the above device has certain advantages during application, it still has obvious defects and shortcomings in actual use. First, its internal structure is not convenient to open quickly, making it difficult to clean the inside of the equipment quickly after cleaning. This can lead to residues left from previous cleaning contaminating subsequent cleaning work and affecting the stability of the cleaning effect. Second, the device lacks a high-strength sealing structure during use. Since the inside of the equipment is usually under high pressure during heating and cleaning, a simple sealing structure cannot achieve a more stable seal, which may not only cause energy loss but also pose certain safety hazards.

[0016] Example: A high-pressure hot water cleaner includes a base 1, with support legs 2 fixedly installed in a ring at equal intervals on the top of the base 1, a top frame 3 fixedly installed on the top of the support legs 2, a tank 4 fixedly installed on the inner side of the top frame 3, an adjustment mechanism 6 fixedly installed in the middle of the back of the top frame 3, a top cover 8 fixedly installed on the outer end of the adjustment mechanism 6, the top cover 8 covering the top of the tank 4, a stirring mechanism 7 fixedly installed in the middle of the top cover 8, a sealing mechanism 9 provided on the outer side of the top cover 8, the outer side of the sealing mechanism 9 being fitted and connected to the inner wall of the tank 4, a drain valve 5 fixedly installed at the bottom of the tank 4, and an ultrasonic generator 10 fixedly installed on one side of the tank 4, with the ultrasonic generating end of the ultrasonic generator 10 located inside the tank 4. The sealing mechanism 9 includes an annular elastic sealing bladder 91 and a piston assembly 92. The annular elastic sealing bladder 91 is fixedly installed on the outside of the top cover 8, and the piston assembly 92 is fixedly installed on the top side of the base 1. The output end of the piston assembly 92 is connected to the inside of the annular elastic sealing bladder 91. During the application of this device, the base 1 provides stable support to the top frame 3 through the support legs 2. The tank 4 inside the top frame 3 is used to carry the liquid required for cleaning and the parts to be cleaned. When cleaning is required, the adjusting mechanism 6 operates, moving the top cover 8 to a position covering the top of the tank 4. At this time, the sealing mechanism 9 on the outside of the top cover 8 begins to function. The piston assembly 92 of the sealing mechanism 9 is activated, and its output end delivers the medium into the annular elastic sealing bladder 91, causing the annular elastic sealing bladder 91 to expand. After expansion, the outside of the annular elastic sealing bladder 91 is tightly fitted with the inner wall of the tank 4, achieving a seal on the tank 4. This sealing method can effectively cope with the pressure that may occur during the cleaning process. Force changes ensure the reliability of the seal, avoiding the problem of easy failure of simple sealing structures under high pressure in existing technologies. During the cleaning process, the stirring mechanism 7 is activated in the middle of the top cover 8 to stir the cleaning fluid and the parts to be cleaned in the tank 4, promoting full contact between the cleaning fluid and the parts and improving cleaning efficiency. At the same time, the ultrasonic generator 10 on one side of the tank 4 works, and its ultrasonic generating end generates ultrasonic waves in the tank 4. The ultrasonic waves enhance the peeling effect of contaminants on the surface of the parts, further improving the cleaning quality. After cleaning, the piston assembly 92 of the sealing mechanism 9 stops conveying the medium, the annular elastic sealing bladder 91 contracts, and releases the contact state with the inner wall of the tank 4. The adjusting mechanism 6 drives the top cover 8 to move open, and then the cleaning waste liquid can be discharged through the drain valve 5 at the bottom of the tank 4. The convenient movement of the top cover 8 makes the subsequent cleaning operation inside the tank 4 more convenient, solving the problem of inconvenient cleaning caused by the difficulty in quickly opening the internal structure in existing technologies.

[0017] Please refer to Figures 1-3 and Figure 5The piston assembly 92 includes a push rod 921 and a side plate 922. The side plate 922 is fixedly installed in the middle of one side of the top cover 8. A piston sleeve 923 is fixedly installed at the bottom of the top cover 8. A piston plate 924 is slidably connected inside the piston sleeve 923. The push rod 921 is fixedly installed on the top side of the base 1. The top of the top cover 8 and the bottom of the piston plate 924 are fitted together. The output end of the piston sleeve 923 is connected to the inside of the annular elastic sealing bladder 91. A return spring 925 is fixedly installed at the upper end of the piston sleeve 923. The bottom of the return spring 925... The top of the piston plate 924 is fixedly connected to the top of the top cover 8. During the operation of this device, as the top cover 8 moves towards the top of the tank 4, the push rod 921 contacts the piston plate 924 and generates a thrust, causing the piston plate 924 to slide upward along the inside of the piston sleeve 923. At this time, the return spring 925 at the upper end of the piston sleeve 923 is compressed by the piston plate 924 and contracts. The movement of the piston plate 924 causes the medium inside the piston sleeve 923 to enter the annular elastic sealing bladder 91 through the output end, pushing the sealing bladder to expand and achieve the sealing of the tank 4. This is achieved through mechanical means. The linkage-based sealing method eliminates the need for an additional power source to drive the sealing mechanism 9, simplifying the operation process. Simultaneously, the elastic potential energy of the return spring 925 stores energy for subsequent seal release, ensuring smooth sealing and release processes. When the cleaning operation is complete and the top cover 8 moves upward, the thrust of the push rod 921 on the piston plate 924 disappears, the return spring 925 returns to its original state, and pushes the piston plate 924 downward along the piston sleeve 923 to reset. A negative pressure is generated inside the piston sleeve 923, drawing back the medium from the annular elastic sealing bladder 91, causing the sealing bladder to contract and release the seal. During this process, the sliding accuracy of the piston plate 924 is limited by the guidance of the piston sleeve 923, ensuring the stability of medium delivery and avoiding the risk of seal failure. Compared to existing sealing methods that rely on manual operation or complex drive structures, the linkage design of this piston assembly 92 improves the automation and reliability of the sealing operation, reduces human error, and ensures timely seal release by the timely reset of the return spring 925, facilitating smooth movement of the top cover 8 and thus improving the overall operating efficiency of the equipment.

[0018] Please refer to Figures 1-3The adjusting mechanism 6 includes a rail frame 61, which is fixedly installed in the middle of the rear side of the top frame 3. A first motor 62 is fixedly installed at the bottom of the rail frame 61. A lead screw 63 is fixedly installed at the output end of the first motor 62. The lead screw 63 is rotatably connected to the inside of the rail frame 61. A slider 64 is threadedly connected to the outer surface of the lead screw 63. The slider 64 is slidably connected to the inside of the rail frame 61. A connecting arm 65 is fixedly installed on the top of the slider 64. The outer end of the connecting arm 65 is fixedly connected to the top of the top cover 8. An electrically controlled pressure relief valve 11 is fixedly installed on one side of the top of the top cover 8, and a pneumatic valve is fixedly installed on the other side of the top of the top cover 8. A pressure sensor 12 is installed, with its detection end penetrating the top cover 8. A temperature sensor 13 is fixedly installed on the rear top of the top cover 8. An electric heating coil 926 is fixedly installed on the inner wall of the tank body 4. During the application of this device, when the top cover 8 needs to be moved, the first motor 62 at the bottom of the rail frame 61 is activated, driving the lead screw 63 at the output end to rotate inside the rail frame 61. The slider 64, threaded to the outer surface of the lead screw 63, slides along the inside of the rail frame 61 under the action of the rotation of the lead screw 63. The connecting arm 65 at the top of the slider 64 moves accordingly, thereby driving the top cover 8 to adjust its position. This method, using a motor-driven lead screw 63, allows for precise control of the movement distance and speed of the top cover 8. Compared to manual adjustment, this is more convenient and efficient, improving operational accuracy. During the cleaning process, the heating coil 926 on the inner wall of the tank 4 is energized and heats the liquid inside. The temperature sensor 13 on the rear side of the top of the top cover 8 monitors the temperature inside the tank 4 in real time, allowing for monitoring of the heating process and ensuring the cleaning fluid temperature meets requirements. Simultaneously, the air pressure sensor 12 on the other side of the top of the top cover 8 monitors the air pressure inside the tank 4 in real time through a detection end penetrating the top cover 8. When the air pressure inside the tank 4 exceeds the limit... When the set value is exceeded, the electrically controlled pressure relief valve 11 on one side of the top of the top cover 8 automatically opens to release the pressure inside the tank 4, avoiding safety problems caused by excessive pressure. This pressure and temperature monitoring and control system makes the equipment operation safer and more stable, reduces failures caused by abnormal pressure or temperature, ensures the smooth progress of the cleaning process, and also improves the service life of the equipment. When it is necessary to open the top cover 8, the first motor 62 starts in reverse, the lead screw 63 drives the slider 64 to slide in reverse, and the connecting arm 65 pulls the top cover 8 to move, realizing the separation of the top cover 8 from the tank 4. The whole process is highly automated and easy to operate.

[0019] Please refer to Figures 1-2 and Figures 4-5The stirring mechanism 7 includes a second motor 71, which is fixedly installed in the middle of the top of the top cover 8. The output end of the second motor 71 passes through the top cover 8 and is connected to a rotating shaft 72 by a hand-tightening bolt. A cleaning support mesh frame 73 is fixedly installed on the outer surface of the rotating shaft 72 in a ring at equal intervals. During the application of this device, when the cleaning operation is in progress, the second motor 71 starts, and the output end begins to operate. Since the output end is connected to the rotating shaft 72 by a hand-tightening bolt, it can drive the rotating shaft 72 to rotate synchronously. The cleaning support mesh frames 73, arranged in a ring at equal intervals on the outer surface of the rotating shaft 72, rotate together with the rotating shaft 72. When the part to be cleaned is placed in the cleaning support mesh frame 73, the rotating mesh frame will cause the part to move in the cleaning solution, ensuring that all parts of the part can fully contact the cleaning solution, enhancing the dissolution and removal of contaminants on the surface of the part by the cleaning solution. The hand-tightened bolts simplify the installation and disassembly of the rotating shaft 72. When maintenance or replacement of the rotating shaft 72 or the cleaning support frame 73 is required, or when different sizes of frames need to be replaced according to the size of the parts to be cleaned, no complicated tools are needed. The operation can be completed simply by manually tightening the bolts, reducing maintenance difficulty and improving the adaptability of the equipment. The annular arrangement design of the cleaning support frame 73 allows multiple parts to be in a reasonable cleaning position at the same time, avoiding the stacking of parts and affecting the cleaning effect. This ensures that each part is cleaned evenly, improving the efficiency and quality of a single cleaning. Throughout the mixing process, the second motor 71 provides stable power output, ensuring the continuous rotation of the rotating shaft 72 and the cleaning support frame 73, allowing the cleaning operation to proceed smoothly and reducing the problem of insufficient cleaning caused by unstable power.

[0020] Operating principle and advantages: Before use, the base 1 is fixed to the top frame 3 by the ring-shaped support legs 2 at the top. The tank 4 inside the top frame 3 is used to hold the cleaning fluid and the parts to be cleaned. The rail frame 61 of the adjusting mechanism 6 is fixed to the rear side of the top frame 3. When the first motor 62 is not started, the lead screw 63 is stationary, and the slider 64 is in the initial position inside the rail frame 61. The connecting arm 65 drives the top cover 8 to cover the top of the tank 4. In the sealing mechanism 9, the annular elastic sealing bladder 91 is fixed to the outside of the top cover 8 and is not pressurized. Its outside is initially in contact with the inner wall of the tank 4. The side plate 922 of the piston assembly 92 is fixed to one side of the top cover 8. The piston sleeve 923 contains the piston... The stopper plate 924 is in its initial position under the action of the return spring 925. The output end of the piston sleeve 923 is connected to the inside of the annular elastic sealing bladder 91 to prepare for sealing. The electrically controlled pressure relief valve 11 on the top of the top cover 8 is closed. The detection ends of the pressure sensor 12 and the temperature sensor 13 extend through the top cover 8 into the tank 4 to detect the pressure and temperature inside the tank 4, respectively. The ultrasonic generator 10 on one side of the tank 4 is connected to the power supply. After startup, its ultrasonic generating end generates ultrasonic waves inside the tank 4. At this stage, all structures are in their initial state, laying the foundation for subsequent operations. The base 1, support legs 2, and top frame 3 work together to ensure the overall stability of the equipment. To ensure smooth operation of subsequent work, when cleaning is required, the top cover 8 is sealed first. The first motor 62 of the adjusting mechanism 6 is started, driving the lead screw 63 to rotate. The slider 64 slides downward along the rail frame 61 under the action of the thread of the lead screw 63. The connecting arm 65 pushes the top cover 8 closer to the top of the tank body 4 until it is completely covered. During the descent of the top cover 8, the top of the piston rod 921 of the piston assembly 92 contacts the bottom of the piston plate 924 and pushes the piston plate 924 to slide upward along the piston sleeve 923, compressing the return spring 925. The upward movement of the piston plate 924 allows the gas or liquid in the piston sleeve 923 to enter the annular structure through the output end. The elastic sealing bladder 91 expands, and its outer side fits tightly against the inner wall of the tank 4, thus sealing the tank 4. During this process, the adjusting mechanism 6 enables the top cover 8 to move quickly. Compared with the inconvenient structure in the prior art, this provides convenience for subsequent cleaning of the inside of the tank 4. The sealing mechanism 9 achieves a high-strength seal through the expansion of the annular elastic sealing bladder 91, which solves the problems of simple sealing structure and unstable sealing under high pressure in the prior art, reduces energy loss and safety hazards. The rail frame 61 provides guidance for the sliding of the slider 64, ensuring the stable lifting and lowering of the top cover 8, and further improving the reliability of the sealing operation.

[0021] After sealing is completed during use, the cleaning process begins. Cleaning fluid is injected into the tank 4. The second motor 71 of the stirring mechanism 7 starts, and the output end of the rotating shaft 72, connected by a hand-tightening bolt, rotates. The cleaning support mesh frame 73 on the outer surface of the rotating shaft 72 rotates with the rotating shaft 72, stirring the components and cleaning fluid placed in the mesh frame to ensure full contact between the components and the cleaning fluid. At the same time, the electric heating coil 926 inside the tank 4 is energized and heats up the cleaning fluid. The temperature sensor 13 monitors the temperature inside the tank 4 in real time to control the degree of heating. The ultrasonic generator 10 on one side of the tank 4 is activated, and its ultrasonic generating end generates ultrasonic waves inside the tank 4. Ultrasonic waves utilize the cavitation effect to further clean contaminants from the surface of components. During the cleaning process, the pressure sensor 12 monitors the pressure inside the tank 4 in real time. When the pressure exceeds the set value, the electrically controlled pressure relief valve 11 automatically opens to release pressure, ensuring the safety of the tank 4. In this process, the stirring mechanism 7, the heating coil 926, and the ultrasonic generator 10 work together to solve the problem of poor cleaning effect in existing technologies, significantly improving the cleaning effect. The temperature sensor 13 facilitates real-time monitoring of the cleaning fluid temperature, enabling precise control of cleaning conditions. The cooperation between the pressure sensor 12 and the electrically controlled pressure relief valve 11 prevents damage to the tank 4 due to high pressure, improving... To ensure the safety of equipment operation; the hand-tightened bolt-connected rotating shaft 72 facilitates disassembly and replacement of the cleaning support frame 73, increasing the flexibility of the equipment. After cleaning, the electric heating coil 926, ultrasonic generator 10, and second motor 71 stop working, the first motor 62 of the adjusting mechanism 6 starts in reverse, the lead screw 63 drives the slider 64 to slide upward along the rail frame 61, the connecting arm 65 pulls the top cover 8 upward, separating it from the top of the tank 4. During the upward movement of the top cover 8, the thrust of the top rod 921 on the piston plate 924 disappears, the return spring 925 returns to its original position and pushes the piston plate 924 downward, releasing the gas or liquid in the annular elastic sealing bladder 91. The liquid flows back to the piston sleeve 923, the sealing bladder contracts, and the tight fit with the inner wall of the tank 4 is released. Then, the drain valve 5 at the bottom of the tank 4 is opened to discharge the cleaning waste liquid. If it is necessary to clean the inside of the tank 4, it can be operated directly through the opened top cover 8. At this stage, the adjustment mechanism 6 plays a role again to realize the quick opening of the top cover 8, which solves the problem of difficult cleaning caused by the inconvenience of opening the internal structure in the prior art. It is convenient to directly clean the inside of the tank 4 and the cleaning support frame 73, and avoids the contamination of the subsequent cleaning by the residue. The setting of the drain valve 5 facilitates the discharge of cleaning waste liquid, making the whole cleaning process smoother and more efficient. During the application of this device, the lead screw 63 of its adjusting mechanism 6 is made of 316 stainless steel, which has the characteristics of corrosion resistance, high strength, and strong weather resistance, and can be used for a long time in air or water. The diameter range is 12mm-20mm, and the length range is 300mm-500mm. The thread accuracy of the slider 64 mating with the lead screw 63 is 6H / 6g.

The barometric pressure sensor 12 is an MPX5700 series, with a measurement range of 0-70℃. The pressure relief valve 11 has a working pressure range of 0.2MPa-1MPa, a nominal diameter of 15mm-25mm, and a working voltage of 24V. The drain valve 5 has a nominal diameter of 20mm-40mm and a working pressure range of 0-1.6MPa. The controller is a PLC controller, specifically model S7-1200, installed on the outer wall of the top frame 3, and connected to the first motor 62, the second motor 71, and the heating coil 926.
