Technical Field

[0001] This application relates to the field of gear cleaning technology, and in particular to a cleaning machine filtration system and a cleaning machine. Background Technology

[0002] Gears often require cleaning during the manufacturing process to remove dirt and debris from their surfaces, facilitating subsequent fine machining. Gear cleaning machines are widely used in machinery manufacturing, repair, and maintenance to remove dirt, oil, and metal shavings from gear surfaces. During the cleaning process, the cleaning solution needs to remain clean for an extended period to ensure effective cleaning and extend the equipment's lifespan.

[0003] However, existing cleaning machine filtration systems generally suffer from problems such as insufficient filtration accuracy and easy contamination of the cleaning medium, which affect the cleaning effect. Utility Model Content

[0004] To ensure the cleanliness of the cleaning medium and improve the gear cleaning effect, this application provides a cleaning machine filtration system and a cleaning machine.

[0005] On the one hand, the cleaning machine filtration system provided in this application adopts the following technical solution:

[0006] A filtration system for a cleaning machine, the filtration system comprising:

[0007] A first liquid storage tank is connected to a first return pipe, which is used to connect to the cleaning chamber of the cleaning machine.

[0008] A filter cake is located at the top of the first liquid storage tank and is used to filter the cleaning liquid discharged from the return pipe of the cleaning chamber.

[0009] The second liquid storage tank is connected to the first liquid storage tank and the second liquid storage tank through an overflow port. The second liquid storage tank has a first liquid outlet, which is used to connect to the inlet of the high-pressure cleaning pump of the cleaning machine.

[0010] An adsorption element is connected to the bottom of the first liquid storage tank and is used to adsorb magnetic metal particles in the cleaning solution.

[0011] Optionally, it also includes a high-precision filter and a centrifugal pump. The second liquid storage tank is also provided with a second liquid outlet, which is used to communicate with the inlet of the centrifugal pump. The outlet of the centrifugal pump is connected to the input end of the high-precision filter, and the output end of the high-precision filter is connected to the second liquid storage tank.

[0012] Optionally, the side wall of the second liquid storage tank is provided with a filter return port, which is connected to the output end of the high-precision filter and is located above the first liquid outlet.

[0013] Optionally, a baffle is fixedly installed in the second liquid storage tank. The height of the baffle corresponds to that of the filter return port, and there is a gap between the baffle and the filter return port.

[0014] Optionally, the first liquid outlet is located above the second liquid outlet.

[0015] Optionally, the bottom walls of the first liquid storage tank and the second liquid storage tank are inclined, and a first slag collection tank is provided at the lower end of the first liquid storage tank, and a second slag collection tank is provided at the lower end of the second liquid storage tank.

[0021] A cleaning machine includes a body and a filtration system disposed within the body.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The cleaning solution in the cleaning chamber is discharged into the filter tray through the first return pipe for preliminary filtration. After filtration through the filter tray, it enters the first storage tank. After being filtered again through the filter screen on the partition, it enters the second storage tank and then enters the high-pressure cleaning pump through the first outlet to complete the gear cleaning operation. A centrifugal pump then pumps liquid from the lowest point of the second storage tank, pumps it into a high-precision filter, and returns it to the second storage tank to form a long-term circulating filtration system. This ensures the cleanliness of the cleaning solution and improves the cleaning effect on the gears.

[0024] 2. The inlet (i.e. the first outlet) of the high-pressure cleaning pump is higher than the lowest point of the second storage tank, which can effectively prevent the cleaning pump from sucking in tiny foreign objects that have settled, and further ensure the cleanliness of the sprayed cleaning solution.

[0038] This application discloses a filtration system for a cleaning machine.

[0039] Reference Figures 1-3 A cleaning machine filtration system includes a liquid storage tank 10, which includes a first liquid storage tank 1 and a second liquid storage tank 2. The first liquid storage tank 1 and the second liquid storage tank 2 are separated by a partition 3, and the first liquid storage tank 1 and the second liquid storage tank 2 are combined to form a box structure.

[0040] Among them, see Figure 2 and Figure 3 The first liquid storage tank 1 is connected to a first return pipe 11, which is used to connect to the cleaning chamber of the cleaning machine. Both the top openings of the first liquid storage tank 1 and the second liquid storage tank 2 can be equipped with a cover plate 4, and the first return pipe 11 is installed on the cover plate 4 of the first liquid storage tank 1. After the cleaning chamber of the cleaning machine operates, the cleaning fluid is discharged into the first liquid storage tank 1 through the first return pipe 11.

[0041] See Figure 2 and Figure 3 The top of the first storage tank 1 is connected to a second return pipe 12, which is used to connect to the oil collector of the cleaning machine. The cleaning machine is equipped with an oil collector; because the cleaning fluid contains oil, the cleaning fluid after oil recovery flows back into the first storage tank 1 through the second return pipe 12. The second storage tank 2 has a first outlet 21, which is used to connect to the inlet of the high-pressure cleaning pump of the cleaning machine.

[0042] See Figure 3 and Figure 4 An overflow port 31 is provided on the partition 3, and the first liquid storage tank 1 and the second liquid storage tank 2 are connected through the overflow port 31. Multiple overflow ports 31 are arranged at intervals along the height direction of the partition 3. To further improve the filtration effect, a filter screen 32 is fixedly installed on the partition 3, and the filter screen 32 is fixedly installed on the partition 3 by screws.

[0043] Optional, see Figure 3 and Figure 5 The filtration system also includes a high-precision filter 5 and a centrifugal pump 51. The second liquid storage tank 2 is also provided with a second liquid outlet 22, which is used to connect with the inlet of the centrifugal pump 51. The outlet of the centrifugal pump 51 is connected with the input end of the high-precision filter 5, and the output end of the high-precision filter 5 is connected with the second liquid storage tank 2. In this embodiment, the high-precision filter 5 is a 5μm high-precision filter 5, which is used to filter out particles of 5μm (micrometers) and above.

[0044] Optionally, the first outlet 21 is located above the second outlet 22, and the second outlet 22 is located at the lowest point of the second storage tank 2. The inlet (first outlet 21) of the cleaning pump, which enters from the second storage tank 2, is higher than the lowest point of the second storage tank 2, which can effectively avoid the cleaning pump sucking in tiny foreign objects that have settled, and further ensure the cleanliness of the sprayed cleaning solution.

[0045] See Figure 3 and Figure 6 The second liquid storage tank 2 has a filter return port 23 on its side wall, which is connected to the output end of the high-precision filter 5. The filter return port 23 is located above the first liquid outlet 21. A baffle 24 is fixedly installed inside the second liquid storage tank 2. The height of the baffle 24 corresponds to that of the filter return port 23, and there is a gap between the baffle 24 and the filter return port 23. The baffle 24 blocks the cleaning liquid discharged from the filter return port 23, reduces the disturbance to the cleaning liquid in the second liquid storage tank 2, and facilitates the settling of fine impurities at the bottom of the second liquid storage tank 2, so that the centrifugal pump 51 can draw the cleaning liquid containing impurities from the bottom of the tank, thereby improving the cleanliness of the cleaning liquid in the second liquid storage tank 2.

[0046] A filter tray 6 is installed at the top of the first storage tank 1 to filter the cleaning fluid discharged from the cleaning chamber return pipe. The filter tray 6 can be made of a perforated plate, which can initially filter out larger impurities in the cleaning fluid.

[0047] See Figure 2 and Figure 6 The first liquid storage tank 1 is equipped with a first liquid level detection module, and the second liquid storage tank 2 is equipped with a second liquid level detection module. Both the first and second liquid level detection modules include a liquid level sensor; and / or, a visual liquid level gauge 721 is provided on the side wall of the second liquid storage tank 2. In this embodiment, a first detection box 71 is fixedly installed on the side wall of the first liquid storage tank 1, and the first detection box 71 is connected to the first liquid storage tank 1. The first liquid level detection module is disposed inside the first detection box 71. A second detection box 72 is fixedly installed on the side wall of the second liquid storage tank 2, and the second detection box 72 is connected to the second liquid storage tank 2. The second liquid level detection module is disposed inside the second detection box 72, and the visual liquid level gauge 721 is disposed on the side wall of the second detection box 72. The first and second liquid level detection modules can detect the liquid level height in the first liquid storage tank 1 and the second liquid storage tank 2, and can also detect the blockage of the filter cake plate 6.

[0048] For easier cleaning, see Figure 6 and Figure 7 The filter cake tray 6 is detachably mounted on the top of the first liquid storage tank 1. Specifically, the top of the first liquid storage tank 1 is provided with a mounting plate 8, and the top of the filter cake tray 6 is integrally formed with a hanging plate 61, which is hung on the mounting plate 8. When it is necessary to remove the filter cake tray 6, first remove the cover plate 4, and then lift the filter cake tray 6 upwards.

[0049] See Figure 6 and Figure 8 The top of the filter cake tray 6 is connected to a filter cake overflow drain, and the bottom of the first detection box 71 is provided with a drain pipe 711, which is connected to the filter cake overflow drain. When the filter cake tray 6 is blocked, the liquid level in the filter cake tray 6 rises, and the cleaning liquid will be discharged from the filter cake overflow drain at the top of the filter cake tray 6.

[0050] Specifically, the end of the mounting plate 8 furthest from the second storage tank 2 is bent upwards to form a drainage tank structure, and the top wall of the filter cake plate 6 is lower than the top wall of the first storage tank 1. A gap exists between the hanging plate 61 and the side wall of the mounting plate 8 near the inner wall of the first storage tank 1, allowing the cleaning fluid to enter the tank through the gap. A drain hole 713 is provided at the bottom of the tank, serving as the overflow drain for the filter cake. The drain hole 713 is connected to a connecting bend 712, which is connected to the first detection box 71. When the filter cake plate 6 is clogged, the cleaning fluid can overflow from the top of the filter cake plate 6 into the tank formed by the mounting plate 8, then enter the connecting bend 712 through the drain hole 713, and finally enter the first detection box 71, exiting through the drain pipe 711.

[0051] Optional, see Figure 3 and Figure 6 The bottom walls of the first liquid storage tank 1 and the second liquid storage tank 2 are inclined. In this embodiment, the bottom walls of the first liquid storage tank 1 and the second liquid storage tank 2 are inclined downwards from the ends that are close to each other to the ends that are far apart from each other. A first sludge collection tank 91 is provided at the lower end of the first liquid storage tank 1, and a second sludge collection tank 92 is provided at the lower end of the second liquid storage tank 2. The first sludge collection tank 91 and the second sludge collection tank 92 are arranged along the width direction of the liquid storage tank 10. A drain outlet 911 is provided on the side wall of the first liquid storage tank 1. The drain outlet 911 is connected to the first sludge collection tank 91 and is used to discharge impurities in the first sludge collection tank 91.

[0052] Optionally, an adsorption element is provided at the bottom of the first liquid storage tank 1 to adsorb magnetic metal particles in the cleaning fluid. In this embodiment, the adsorption element can be a magnet, which is disposed on the outer bottom wall of the first liquid storage tank 1. The first liquid storage tank 1 is made of metal, such as iron.

[0053] The implementation principle of this embodiment is as follows: The cleaning fluid in the cleaning chamber is discharged into the filter tray 6 through the first return pipe 11 for preliminary filtration. After filtration through the filter tray 6, it enters the first storage tank 1, and after being filtered again through the filter screen 32 on the partition 3, it enters the second storage tank 2. It then enters the high-pressure cleaning pump through the first outlet 21 to complete the gear cleaning operation. The centrifugal pump 51 then pumps the fluid from the lowest point of the second storage tank 2, pumps it into the high-precision filter 5, and returns it to the second storage tank 2 to form a long-term circulating filtration, ensuring the cleanliness of the cleaning fluid.

[0054] The inlet (i.e., the first outlet 21) of the high-pressure cleaning pump is higher than the lowest point of the second storage tank 2, which can effectively prevent the cleaning pump from sucking in tiny foreign objects that have settled, and further ensure the cleanliness of the sprayed cleaning solution.

[0055] This application also discloses a cleaning machine.

[0056] Reference Figure 1 A cleaning machine includes a body 20 and a filtration system disposed within the body 20.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
