Description

Technical Field

[0001] This utility model relates to the technical field of bubble cleaning machine equipment, and more specifically, to a circulating water bubble cleaning machine. Background Technology

[0002] A bubble cleaner is a device that uses the impact force of bubbles and water flow to clean items. Its working principle involves injecting air into water through a bubble generator, forming numerous tiny bubbles. These bubbles are evenly distributed throughout the surface of the items to be cleaned. As the bubbles rise, they come into contact with the material, and the impact force generated when the bubbles burst removes dirt, impurities, and microorganisms from the surface. Simultaneously, the tumbling and flowing action of the bubbles causes the items to tumble and move in the water, ensuring that the water flow reaches every corner of the item more thoroughly.

[0003] Existing bubble cleaning machines often waste water during the cleaning process, and the direct discharge of wastewater after cleaning also puts pressure on the environment. At the same time, the cleaning effect of some cleaning machines is not ideal. Some residues that are removed after bubble cleaning will re-adhere to the materials during material movement, making it impossible to clean them thoroughly.

[0004] A Chinese utility model patent, titled "A Circulating Water Bubble Cleaning Machine" with publication number CN222366997U, includes a cleaning tank mechanism, a lifting mechanism, and a cleaning mechanism. The lifting mechanism is located outside the cleaning tank mechanism, while the cleaning mechanism is situated at the top of the cleaning tank mechanism. The cleaning tank mechanism comprises a cleaning tank body and a conveyor belt. A gantry frame is installed within the lifting mechanism and is driven by a first motor. In this utility model, by moving the conveyor belt upwards, a gap is created between the conveyor belt and the cleaning tank, facilitating the cleaning of debris inside the cleaning tank.

[0005] Although this invention can improve the speed of cleaning residual residue inside the cleaning tank and improve the cleaning efficiency of materials by using a brush, it has a low water flow utilization rate and cannot directly clean the debris inside the cleaning tank during the cleaning process.

[0016] Preferably, the high-pressure water spray head and the slag discharge port are connected by a filtration and circulation system.

[0017] Preferably, the filtration circulation system includes a pipe assembly, a pump assembly, and a filter assembly.

[0018] Preferably, the water flow filtration and circulation process is as follows: slag discharge port - filter assembly - pump assembly - pipe assembly - high-pressure water spray head.

[0019] Preferably, a filter assembly is fixedly installed on the frame. The inlet of the filter assembly is connected to the slag discharge port, and the outlet of the filter assembly is connected to the first pump assembly. The first pump assembly is connected to the pipe assembly, and all the high-pressure water spray heads are connected to the pipe assembly.

[0020] Preferably, the bottom of the cleaning chamber below the conveyor belt is connected to the outlet of the second pump pressure assembly, and the pump outlet of the second pump pressure assembly is connected to an external water supply port.

[0021] Preferably, the second pump assembly includes a water outlet branch pipe, a second water pump, a flushing pipe, and a water outlet valve pipe.

[0022] Preferably, there are two water outlet branches. One water outlet branch is connected to the outlet of the filter assembly, and the other water outlet branch is connected to the water supply port of the external water source. Both water outlet branches are connected to the pump port of the second water pump. The outlet of the second water pump is connected to one end of the flushing pipe, and the other end of the flushing pipe is connected to the bottom of the cleaning chamber.

[0023] Preferably, the bottom of the cleaning chamber is also connected to a water outlet valve pipe.

[0024] Preferably, the cleaning chamber is provided with two guide plates, which divide the cleaning chamber into three cleaning zones. The water flow in adjacent cleaning zones is in opposite directions, and the adjacent cleaning zones are connected end to end.

[0025] Preferably, the water flow direction in the central cleaning zone of the cleaning chamber is from the outlet to the inlet; the water flow direction in the cleaning zones on both sides of the cleaning chamber is from the inlet to the outlet.

[0026] Preferably, the guide plate includes a baffle plate, a connecting rod, and a guide port.

[0027] Preferably, the at least one baffle is fixedly installed in the cleaning chamber by a connecting rod, with the bottom of the baffle positioned above the conveyor belt and the top of the baffle higher than the water level in the cleaning chamber.

[0030] The technical solution of this application has at least the following advantages and beneficial effects:

[0031] In this invention, a guide plate is used to divide the cleaning chamber into multiple cleaning zones with different water flow directions. Each cleaning zone is equipped with a set of high-pressure water nozzles with the same spray direction to spray water onto the water surface. Two cleaning zones with different water flow directions are connected end to end to form a water circulation, which accelerates the water flow rate. The impurities washed from the material will float on the water surface and then converge to the feed inlet of the cleaning zone with the water circulation. A slag discharge port connected to the cleaning chamber is provided at the feed inlet to remove the accumulated impurities and prevent the floating impurities from continuing to adhere to the material surface during the material transportation process, thereby improving the cleaning degree.

[0032] In this invention, a filtration and circulation system is used to connect the high-pressure water nozzle and the slag discharge port, so that the water after the slag discharge port has filtered impurities is pumped back into the high-pressure water nozzle, thereby realizing the recycling of the cleaning water.

[0033] In this invention, a second pump assembly is connected to the bottom of the cleaning chamber. The second pump assembly is connected to an external water supply port. By pumping water at the bottom of the cleaning chamber below the conveyor belt, the water flows and carries suspended impurities along with it. The water then flows out from the outlet at the bottom of the cleaning chamber, reducing the accumulation of impurities at the bottom of the cleaning chamber and minimizing the impact of impurities on the cleaning effect of the bubble cleaner below the conveyor belt.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In the prior art, the bubble cleaning machine has a water injection chamber inside, with a water spray head at the top and a bubble generator at the bottom. The material to be cleaned is then fed into the water injection chamber through the feed inlet, and the water spray head is used to rinse the surface of the material. The sprayed water is stored in the water injection chamber, and then the bubble generator generates bubbles. The bubbles burst and clean the material in the water injection chamber. The cleaned material is then conveyed to the discharge port by a conveyor belt for collection.

[0046] Example

[0047] Please refer to Figures 1-8 This utility model provides a circulating water bubble cleaning machine, including a frame 1, a conveyor belt 2, a bubble generator 3, a high-pressure water spray head 6, and a guide plate 7.

[0048] The frame 1 is equipped with a feed inlet 101 and a discharge outlet 102. A cleaning chamber is set inside the frame 1, and a conveyor belt 2 is set inside the cleaning chamber. The two ends of the conveyor belt 2 are the feed inlet 101 and the discharge outlet 102, respectively. The conveyor belt 2 sends the material entering from the feed inlet 101 into the cleaning chamber for cleaning and then sends it to the discharge outlet 102.

[0049] The cleaning chamber is equipped with a bubble generator 3 located below the conveyor belt 2, and a high-pressure water spray head 6 is installed above the conveyor belt 2.

[0050] The inlet of the high-pressure water spray head 6 is connected to the water supply port of an external water source, and water is supplied by a pump at the external water source. The high-pressure water spray head 6 sprays water into the cleaning chamber to wash the materials. The bubble generator 3 generates bubbles in the water in the cleaning chamber to achieve a better cleaning effect on the materials.

[0051] In this embodiment, at least one guide plate 7 is provided above the conveyor belt 2 within the cleaning chamber. The guide plate 7 divides the cleaning chamber into at least two water flow zones. The water flow direction refers to either from the inlet to the outlet 102 or from the outlet 102 to the inlet 101.

[0052] A set of high-pressure water nozzles 6 with the same spray direction is provided above each cleaning zone. By setting the spray angle of the set of high-pressure water nozzles 6, the water flow direction in the cleaning zone is made to be the required water flow square (i.e. from the material inlet to the discharge outlet 102 or from the discharge outlet 102 to the inlet 101).

[0053] Two cleaning zones with opposite water flow directions are connected end to end, forming a water circulation on the water surface above the conveyor belt 2. The circulation direction is: inlet 101 of one cleaning zone - outlet 102 of one cleaning zone - outlet 102 of another cleaning zone - inlet 101 of another cleaning zone.

[0054] The purpose of this design is that the impurities from the washing process will float on the surface of the water and then circulate with the water flow to the inlet 101 of another cleaning zone. At the inlet 101, there is a slag discharge port that communicates with the cleaning chamber and is located above the conveyor belt, thereby removing the accumulated impurities.

[0055] Furthermore, the conveyor belt 2 is provided with a discharge position, which is inclined upward, so that the discharge port 102 is higher than the cleaning chamber. With this structural setting, the discharge port 102 is located above the water level in the cleaning chamber, and the water cannot flow out from the discharge port 102.

[0056] Example 2

[0057] Please refer to Figure 3 and Figure 4 In this embodiment, in order to obtain a better impurity circulation and aggregation effect, two guide plates 7 are provided in the cleaning chamber. The two guide plates 7 divide the cleaning chamber into three cleaning zones, and the water flow direction in adjacent cleaning zones is opposite.

[0058] The three cleaning zones are sprayed with water from high-pressure water nozzles located above them. The water flow direction in the central cleaning zone is from the discharge port 102 to the inlet 101; the water flow direction in the two side cleaning zones is from the inlet 101 to the discharge port 102. Because the adjacent cleaning zones are connected end to end, a water circulation will be formed on the water surface of the adjacent cleaning zones. The circulation direction is: inlet 101 of the two side cleaning zones - discharge port 102 of the two side cleaning zones - discharge port 102 of the central cleaning zone - inlet 101 of the central cleaning zone - inlet 101 of the two side cleaning zones.

[0059] Because the three cleaning zones are located above the conveyor belt 2, the central cleaning zone is located in the middle of the width of the conveyor belt 2 and is the main area for conveying materials. The amount of material in the central cleaning zone is greater than that in the two side cleaning zones, resulting in more impurities being washed away. Therefore, the water flow from the two side cleaning zones circulates to the central cleaning zone, increasing the water flow in the central cleaning zone and thus increasing the slag discharge efficiency of the central cleaning zone.

[0060] Example 3

[0061] Please refer to Figures 3-5 In this embodiment, the guide plate 7 includes a baffle plate 701, a connecting rod 702, and a guide port 703.

[0062] Specifically, the baffle plate 701 is fixedly installed in the cleaning chamber by the connecting rod 702. The bottom of the baffle plate 701 is placed above the conveyor belt 2 (with a gap between it and the belt surface, so as not to affect the conveying of the conveyor belt 2). The top of the baffle plate 701 is located on the water surface in the cleaning chamber. While separating multiple cleaning zones relatively completely above the conveyor belt 2, it isolates the water surface of multiple cleaning zones to realize water circulation at the water surface.

[0063] The two ends of the baffle 701 are close to the inlet 101 and the outlet 102 respectively, and there are gaps between them, so that the adjacent cleaning zones separated by the baffle 701 are connected end to end, forming a water circulation.

[0064] Furthermore, when two baffles 701 are installed in the cleaning chamber (i.e., there is a central cleaning zone and two side cleaning zones), a number of guide ports 703 are evenly arranged on the baffles 701 along the direction of water flow, and the guide ports 703 connect to the adjacent cleaning zones.

[0065] The purpose of this design is that when the water circulates within the cleaning zone, the flow direction of impurities at the water surface in both cleaning zones is: cleaning zone chamber - cleaning zone outlet 102 - central cleaning zone outlet 102 - central cleaning zone inlet 101 - slag discharge port. Impurities require a large circulation path to be discharged, easily leading to excessive accumulation in the cleaning zones. The guide port 703 connects the cleaning zones and the central cleaning zone. Utilizing the higher water velocity in the central cleaning zone (water from the two side cleaning zones circulates into one central cleaning zone, resulting in a higher flow velocity), this velocity difference directly guides some impurities from the side cleaning zones to the central cleaning zone, where they then flow from the central cleaning zone chamber into the slag discharge port, accelerating the collection and discharge of impurities.

[0066] Example 4

[0067] Please refer to Figure 6 and Figure 7In this embodiment, the high-pressure water spray head 6 and the slag discharge port are connected by a filtration and circulation system, so that the water flow after the impurities are filtered out at the slag discharge port is pumped back into the high-pressure water spray head 6 to realize the recycling of the cleaning water flow.

[0068] The filtration circulation system includes pipe assembly 4, pump assembly 5, and filter assembly 8.

[0069] The process of circulating the cleaning water flow is as follows: slag discharge port - filter assembly 8 - pump assembly 5 - pipe assembly 4 - high-pressure spray head 6.

[0070] Specifically, a filter assembly 8 is fixedly installed on the frame 1. The inlet of the filter assembly 8 is connected to the slag discharge port, so that water containing impurities flows into the filter assembly 8, the impurities are filtered out by the filter element, and the filtered clean water flows out from the outlet of the filter assembly 8 and into the pump assembly 5 connected to the outlet.

[0071] The pump assembly 5 includes a water pump 501 and a main outlet pipe 502. One end of the main outlet pipe 502 is connected to the outlet of the filter assembly 8, and the other end of the main outlet pipe 502 is connected to the pump inlet of the water pump 501. Clean water is pumped out of the filter assembly 8. The outlet of the water pump 501 is connected to the pipe group 4. All the high-pressure water nozzles 6 are connected to the pipe group 4. After the clean water is pumped out into the pipe group 4, it supplies water to the high-pressure water nozzles 6, reducing the amount of external water used.

[0072] It is worth noting that pipe assembly 4 is connected to pump pressure assembly 5 and the water supply port of external water source. At the beginning of bubble cleaning, there is no filtered water flow inside filter assembly 8, the filter circulation system is in the closed state, pump pressure assembly 5 is closed, and pipe assembly 4 supplies water to high-pressure spray head 6 only through external water source. After bubble cleaning has been going on for a period of time, impurities are discharged into filter assembly 8. At this time, the filter circulation system is in the open state, pump pressure assembly 5 is opened, and pipe assembly 4 supplies water to high-pressure spray head 6 through pump pressure assembly 5 and external water source at the same time, saving external water source.

[0073] Example 5

[0074] Because the impurity aggregation effect achieved by the water circulation in the cleaning chamber only applies to the cleaning chamber above the conveyor belt 2, some impurities or impurity clumps sink to the bottom of the cleaning chamber below the conveyor belt 2 due to their weight and are suspended, making it difficult to remove the slag through water circulation.

[0075] Please refer to Figures 5-8In this embodiment, a pump assembly 2 9 is connected to the bottom of the cleaning chamber. The pump assembly 2 9 is connected to an external water supply port. By pumping water to the bottom of the cleaning chamber below the conveyor belt 2, the water flows and carries suspended impurities along with it. Then, they flow out from the outlet set at the bottom of the cleaning chamber, reducing the accumulation of impurities at the bottom of the cleaning chamber and reducing the impact of impurities on the cleaning effect of the bubble cleaner below the conveyor belt 2.

[0076] Pump assembly 29 includes a water outlet branch pipe 901, a water pump 2 902, a flushing pipe 903, and a water outlet valve pipe 904.

[0077] Specifically, there are two outlet branch pipes 901. One outlet branch pipe 901 is connected to the outlet of the filter assembly 8, and the other outlet branch pipe 901 is connected to the water supply port of the external water source. Both outlet branch pipes 901 are connected to the pump port of the second water pump 902 to provide pump water for the second water pump 902 and reduce the use of external water source.

[0078] The outlet of water pump 2 902 is connected to one end of flushing pipe 903, and the other end of flushing pipe 903 is connected to the bottom of the cleaning chamber. High-pressure water flow is flushed into the bottom of the cleaning chamber through flushing pipe 903 to flush out suspended or deposited impurities (or impurity clumps), so that the impurities and flowing water are mixed together. The bottom of the cleaning chamber is also connected to water outlet valve pipe 904. When the valve of water outlet valve pipe 904 is opened, the impurity mixed water flow is left to the outside, reducing impurities at the bottom of the cleaning chamber.

[0079] It is worth noting that during the bubble cleaning process, the pump pressure component 29 operates as follows: after the material has been bubble cleaned for a period of time, the pump pressure component 29 is started to flush the bottom of the cleaning chamber with high pressure for a short time to remove slag, and then the pump pressure component 29 is turned off. It is then restarted after a period of time, thereby reducing the amount of water used.

[0080] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
