Description

Technical Field

[0001] This utility model relates to the field of energy-saving and environmental protection technology, and in particular to a cleaning system. Background Technology

[0002] In existing cleaning systems, hot water is typically used first to clean the workpiece, effectively removing various dirt and impurities from its surface and ensuring the cleanliness meets the requirements of subsequent processes. Then, hot dry air is blown onto the workpiece surface using a drying unit to quickly evaporate any remaining water, completing the drying process. However, the hot water used for cleaning becomes wastewater, requiring purification before discharge to meet environmental emission standards. Simultaneously, the hot, humid air generated during the drying process is directly released into the environment. This approach results in the ineffective recovery and utilization of the heat, water resources, and energy contained in the hot water and humid air, leading to a waste of energy and resources. Utility Model Content

[0003] Given the above situation, it is necessary to provide a clean system to reduce energy consumption.

[0004] This application provides a cleaning system, including:

[0005] A spraying device is used to spray hot cleaning liquid onto the workpiece to clean the workpiece and to discharge the hot waste liquid after spraying.

[0006] A drying device, disposed adjacent to the spraying device, is used to blow hot dry air onto the workpiece to dry the cleaned workpiece and to discharge the hot, humid air after drying; and

[0007] A heat exchange device includes a first heat exchange element, a filter element, a second heat exchange element, and a condenser element. The first heat exchange element is connected to the spraying device and the drying device respectively. The first heat exchange element is used to reduce the temperature of the hot waste liquid to form room temperature waste liquid. The filter element is connected to the first heat exchange element and is used to filter the room temperature waste liquid to form room temperature cleaning liquid. The second heat exchange element is connected to the filter element, the spraying device, and the drying device respectively. The second heat exchange element is used to exchange heat between the room temperature cleaning liquid and the hot humid air to form room temperature humid air and hot cleaning liquid. The condenser element is connected to the second heat exchange element and the first heat exchange element respectively. The condenser element is used to condense the room temperature humid air to form room temperature dry air and deliver the room temperature dry air to the first heat exchange element so that the room temperature dry air forms hot dry air after passing through the first heat exchange element.

[0008] In operation, the cleaning system described above firstly sprays hot cleaning liquid onto the workpiece to clean it and discharges the hot waste liquid after spraying. A drying device then blows hot dry air onto the workpiece to dry it, thus completing the cleaning and drying process. Next, a first heat exchanger receives the hot waste liquid, and a second heat exchanger receives the hot humid air. The first heat exchanger then lowers the temperature of the hot waste liquid to form room-temperature waste liquid, and a filter filters the room-temperature waste liquid to form room-temperature cleaning liquid, which is then conveyed to the second heat exchanger. Simultaneously, the second heat exchanger exchanges heat between the hot humid air and the room-temperature cleaning liquid to form room-temperature humid air and hot cleaning liquid, and then conveys the room-temperature humid air to a condenser. The condenser condenses the room-temperature humid air to form room-temperature dry air, which is then conveyed to the first heat exchanger to form hot dry air. Finally, the first heat exchanger conveys the hot dry air to the drying device for recycling, and the second heat exchanger conveys the hot cleaning liquid to the spraying device for recycling. Thus, the above-mentioned cleaning system achieves efficient cleaning and drying of workpieces by setting up spray and drying devices. By setting up heat exchange devices, it achieves heat exchange and recycling of hot waste liquid and hot humid air generated during the workpiece cleaning process, effectively recovering heat, liquid and air resources, reducing energy waste, and lowering energy consumption and operating costs.

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

[0033] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0034] Please see Figure 1 This application provides a cleaning system 100, including a spraying device 10, a drying device 20, and a heat exchange device 30. The cleaning system 100 is used to clean workpieces. The workpieces can be plates, shells, etc.

[0035] The spraying device 10 is used to spray hot cleaning liquid onto the workpiece to clean it and to discharge the hot waste liquid after spraying. The drying device 20 is arranged adjacent to the spraying device 10. The drying device 20 is used to blow hot dry air onto the workpiece to dry the cleaned workpiece and to discharge the hot humid air after drying. The heat exchange device 30 includes a first heat exchange element 31, a filter element 32, a second heat exchange element 33, and a condenser element 34. The first heat exchange element 31 is connected to the spray device 10 and the drying device 20 respectively. The first heat exchange element 31 is used to reduce the temperature of the hot waste liquid to form room temperature waste liquid. The filter element 32 is connected to the first heat exchange element 31 and is used to filter the room temperature waste liquid to form room temperature cleaning liquid. The second heat exchange element 33 is connected to the filter element 32, the spray device 10, and the drying device 20 respectively. The second heat exchange element 33 is used to exchange heat between the room temperature cleaning liquid and the hot humid air to form room temperature humid air and hot cleaning liquid. The condenser element 34 is connected to the second heat exchange element 33 and the first heat exchange element 31 respectively. The condenser element 34 is used to condense the room temperature humid air to form room temperature dry air and deliver the room temperature dry air to the first heat exchange element 31 so that the room temperature dry air forms hot dry air through the first heat exchange element 31. For example, the first heat exchanger 31 and the second heat exchanger 33 can be any exchange section, exchange body or similar exchange block capable of heat exchange.

[0036] In use, the cleaning system 100 described above firstly sprays hot cleaning liquid onto the workpiece using the spraying device 10 to clean it and then discharges the hot waste liquid after spraying. The drying device 20 blows hot dry air onto the workpiece to dry it, thus completing the cleaning and drying operation of the workpiece. Then, the first heat exchanger 31 receives the hot waste liquid, and the second heat exchanger 33 receives the hot humid air. Next, the first heat exchanger 31 lowers the temperature of the hot waste liquid to form room temperature waste liquid, and the filter 32 filters the room temperature waste liquid to form room temperature cleaning liquid, and then delivers the room temperature cleaning liquid to the second heat exchanger 33. The heat exchanger 33, along with the second heat exchanger 33, facilitates heat exchange between the hot, humid air and the room-temperature cleaning liquid to form room-temperature humid air and hot cleaning liquid. The room-temperature humid air is then transported to the condenser 34, where it condenses to form room-temperature dry air. This dry air is then transported to the first heat exchanger 31, where it is transformed into hot dry air. Finally, the first heat exchanger 31 transports the hot dry air to the drying device 20 for recycling, while the second heat exchanger 33 transports the hot cleaning liquid to the spray device 10 for recycling. Thus, the cleaning system 100, by incorporating the spray device 10 and the drying device 20, achieves efficient cleaning and drying of the workpiece. The heat exchanger 30 enables heat exchange and recycling of the hot waste liquid and hot, humid air generated during the workpiece cleaning process, effectively recovering heat, liquid, and air resources, reducing energy waste, and lowering energy consumption and operating costs.

[0037] It is understood that the "room temperature" mentioned above refers to the temperature close to the operating environment of the cleaning system 100. The "hot" in the terms "hot cleaning liquid," "hot waste liquid," "hot dry air," and "hot humid air" refers to a temperature higher than "room temperature." This application can also adjust the "room temperature" and "hot" temperature according to the usage needs of the cleaning system 100. Specifically, in this embodiment, the "room temperature" is 20℃ and the "hot" temperature is 45℃, thereby ensuring that the hot cleaning liquid effectively cleans the workpiece and the hot dry air effectively dries the workpiece, while avoiding excessively high temperatures of the hot cleaning liquid and hot dry air that could cause workpiece deformation. The cleaning liquid mentioned above refers to a liquid that meets preset standards, and the waste liquid refers to a liquid that does not meet preset standards after use by the spray device 10. In this embodiment, the liquid is water, and the preset standards refer to water with no obvious particulate matter and a conductivity <3µm / cm. The dry air mentioned above refers to air with a relative humidity lower than a predetermined standard, and the humid air refers to air with a relative humidity higher than a predetermined standard. In this embodiment, the predetermined standard is a relative humidity of 15%.

[0038] In some embodiments, the spraying device 10 includes a rinsing component 11, a spraying component 12, a liquid collecting component 13, and a distributing component 14. The rinsing component 11 is disposed adjacent to the drying device 20 and is used to rinse the workpiece with hot cleaning liquid and discharge hot waste liquid. The spraying component 12 is disposed between the rinsing component 11 and the drying device 20 and is used to spray hot cleaning liquid onto the surface of the rinsed workpiece and discharge hot waste liquid. The liquid collecting component 13 is connected to the rinsing component 11, the spraying component 12, and the first heat exchanger 31, respectively, and is used to collect hot waste liquid and transport it to the first heat exchanger 31. The distributing component 14 is connected to the rinsing component 11, the spraying component 12, and the second heat exchanger 33, respectively, and is used to distribute hot cleaning liquid to the rinsing component 11 and the spraying component 12. For example, the rinsing component 11 can be any rinsing section, rinsing body, or similar rinsing tank capable of rinsing the workpiece; the spraying component 12 can be any spraying section, spraying body, or similar spray head capable of spraying hot cleaning liquid onto the workpiece; the liquid collecting component 13 can be any liquid collecting section, liquid collecting plate, or similar liquid collecting plate capable of collecting hot waste liquid; and the distributing component 14 can be any distributing section, distributing body, or similar distributing tank capable of distributing hot cleaning liquid to the rinsing component 11 and the spraying component 12.

[0039] Thus, by setting the specific structure of the spray device 10, the rinsing component 11 can first rinse the workpiece to remove solidified dirt, debris, etc., and then the spraying component 12 can spray the workpiece to remove the dirt adhering to the workpiece, thereby improving the cleaning effect. In addition, the liquid collecting component 13 effectively collects the hot waste liquid after use of the rinsing component 11 and the spraying component 12, which is convenient to be centrally transported to the first heat exchange component 31 for recycling. Furthermore, the distributing component 14 can reasonably distribute the hot cleaning liquid to ensure the flow rate requirements of the liquid used by the rinsing component 11 and the spraying component 12, further improving the cleaning efficiency and quality.

[0040] In some embodiments, the spray device 10 further includes a liquid supply component 15 connected to the dispensing component 14, the liquid supply component 15 being used to replenish the hot cleaning liquid to the dispensing component 14. Exemplarily, the liquid supply component 15 can be any liquid supply section, liquid supply, or similar liquid supply tank capable of replenishing the hot cleaning liquid to the dispensing component 14.

[0041] Thus, by setting up the above-mentioned liquid supply component 15, hot cleaning fluid can be replenished to the distribution component 14 in a timely manner, ensuring a stable supply of hot cleaning fluid during the cleaning process of the workpiece, avoiding incomplete cleaning or interruption due to lack of hot cleaning fluid, thereby improving the stability and continuity of the cleaning system 100.

[0042] In some embodiments, the filter element 32 includes a first filter body 321, a temporary storage body 322, and a second filter body 323 connected in sequence. The first filter body 321 is connected to a first heat exchanger 31, and the second filter body 323 is connected to a second heat exchanger 33. The first filter body 321 and the second filter body 323 cooperate to filter room temperature waste liquid to form room temperature cleaning liquid. The temporary storage body 322 is used to store the room temperature cleaning liquid to control the liquid flow rate from the first filter body 321 to the second filter body 323 via the temporary storage body 322. Exemplarily, the first filter body 321 and the second filter body 323 can be any filter section, filter plate, or similar filter membrane capable of filtering liquid, and the temporary storage body 322 can store room temperature cleaning liquid and deliver room temperature cleaning liquid to the second filter body 323 via any temporary storage section, temporary storage element, or similar temporary storage tank.

[0043] Thus, by setting up the first filter body 321 and the second filter body 323 as described above, the room temperature waste liquid is filtered step by step, which improves the filtration effect and ensures the quality of the room temperature cleaning liquid. Furthermore, by setting up the aforementioned temporary storage body 322, when the flow rate of the room-temperature waste liquid delivered from the first heat exchanger 31 to the first filter body 321 is small, the temporary storage body 322 mixes the stored room-temperature cleaning liquid with the room-temperature cleaning liquid filtered by the first filter body 321, and delivers the mixed room-temperature cleaning liquid to the second filter body 323. This avoids the filter body 32 from experiencing low hydraulic pressure due to insufficient liquid flow, thus preventing it from effectively filtering the room-temperature waste liquid. When the flow rate of the room-temperature waste liquid delivered from the first heat exchanger 31 to the first filter body 321 is large, the temporary storage body 322 stores the room-temperature cleaning liquid filtered by the first filter body 321. This prevents a large flow rate of room-temperature cleaning liquid from directly entering the second filter body 323, which could overload the filter medium of the second filter body 323 and affect the filtration effect. Therefore, by storing room-temperature cleaning liquid in the temporary storage body 322, the liquid flow rate is controlled, thereby improving the filtration efficiency and stability of the filter body 32.

[0044] In some embodiments, the heat exchange assembly further includes a liquid reservoir 35 connected to the filter 32, the liquid reservoir 35 being used to replenish the filter 32 with hot cleaning fluid. Exemplarily, the liquid reservoir 35 can be any liquid storage section, liquid storage tank, or similar container capable of replenishing the filter 32 with hot cleaning fluid.

[0045] Thus, by setting up the aforementioned liquid storage component 35, hot cleaning liquid can be replenished to the filter component 32, ensuring a sufficient supply of hot cleaning liquid during the filtration process, avoiding incomplete or interrupted filtration due to lack of liquid, and further improving filtration efficiency and stability.

[0046] It is understandable that when the cleaning system 100 experiences a water shortage or is shut down, bacteria may grow in the components of the filter element 32 due to the prolonged shutdown, thus affecting the filtration effect of the filter element 32 during normal operation. In the event of a lack of liquid or shutdown, hot cleaning liquid is promptly replenished to the filter element 32 through the liquid storage device 35 to ensure the continuous operation of the filter element 32 and to guarantee the filtration effect and quality of the filter element 32 during the subsequent normal operation of the cleaning system 100.

[0047] In some embodiments, the condenser 34 includes a first separator 341, a condenser 342, and a second separator 343 connected in sequence. The first separator 341 is connected to the second heat exchanger 33 and is used to separate room-temperature cleaning liquid from the hot, humid air output by the second heat exchanger 33. The condenser 342 is used to condense the room-temperature cleaning liquid in the hot, humid air to form room-temperature dry air. The second separator 343 is connected to the first heat exchanger 31 and is used to separate room-temperature cleaning liquid from the room-temperature dry air output by the condenser 342. Exemplarily, the first separator 341 and the second separator 343 can be any separator, separator plate, or similar separator membrane capable of separating water contained in the air, and the condenser 342 can be any condenser, condenser plate, or similar condenser tube capable of condensing the room-temperature cleaning liquid in the hot, humid air.

[0048] Thus, by setting the specific structure of the condenser 34, the first separator 341 and the condenser 342 can effectively separate and condense the room temperature cleaning liquid in the hot and humid air, improve the condensation effect, and ensure the quality of the room temperature dry air. At the same time, the second separator 343 can further separate a small amount of room temperature cleaning liquid in the room temperature dry air, thereby improving the water resource recycling rate and the quality of the room temperature dry air.

[0049] In some embodiments, the heat exchange assembly further includes a connector 36, which is connected to the condenser 34 and the second heat exchanger 33 respectively. The connector 36 is used to deliver the room-temperature cleaning liquid formed after condensation in the condenser 34 to the second heat exchanger 33. Exemplarily, the connector 36 can be any connector, connection part, or similar connecting pipe that delivers the room-temperature cleaning liquid produced in the condenser 34 to the second heat exchanger 33.

[0050] Thus, by setting the aforementioned connector 36, the connector 36 can transport the condensed room-temperature cleaning liquid to the second heat exchanger 33, thereby realizing the recycling of water resources, improving the utilization rate of water resources, and further reducing the cost of use.

[0051] In some embodiments, the drying apparatus 20 includes a drying component 21, an air collection component 22, and an air supply component 23. The drying component 21 is disposed on one side of the spraying device 10 and connected to a first heat exchanger 31. The drying component 21 is used to blow hot dry air onto the cleaned workpiece and discharge hot humid air. The air collection component 22 is connected to the drying component 21 and a second heat exchanger 33, respectively. The air collection component 22 is used to collect the hot humid air discharged from the drying component 21 and transport it to the second heat exchanger 33. The air supply component 23 is connected to the drying component 21 and is used to supplement the hot dry air to the drying component 21. Exemplarily, the drying component 21 can be any drying section, drying body, or similar drying tank capable of drying the workpiece; the air collection component 22 can be any air collection section, air collection body, or similar air collection pipe capable of collecting hot humid air; and the air supply component 23 can be any air supply section, gas supply, or similar air supply valve capable of supplementing the hot dry air to the drying component 21.

[0052] Thus, by setting the specific structure of the drying device 20, the air supply component 23 can replenish the hot dry air to the drying device 20 in a timely manner, ensuring a stable supply of hot dry air during the drying process, improving the drying effect and efficiency, avoiding incomplete drying or interruption due to lack of air, and improving the stability and continuity of the cleaning system 100; in addition, the air collection component 22 effectively collects the hot and humid air discharged after the drying component 21 is used, which is convenient to be centrally transported to the second heat exchange component 33 for circulation processing.

[0053] In some embodiments, the drying member 21 has a vibrator 211 for vibrating the workpiece within the drying member 21. Exemplarily, the vibrator 211 can be any vibrating part, vibrating element, or similar vibrating plate capable of vibrating the workpiece within the drying member 21.

[0054] Thus, by setting the aforementioned vibrator 211, the workpiece inside the drying component 21 can be vibrated, causing the water stains on the surface of the workpiece to atomize, thereby increasing the contact area with the hot dry air, and thus improving the drying effect and efficiency. At the same time, the vibrator 211 can also prevent the workpiece from sticking or deforming during the drying process, thereby improving the quality and stability of the workpiece.

[0055] In some embodiments, the first heat exchanger 31 has a purification body 311 for purifying the hot dry air conveyed to the drying apparatus 20 via the first heat exchanger 31. Exemplarily, the purification body 311 can be any purification section, purification membrane, or similar purification plate for purifying hot dry air.

[0056] Thus, by setting up the purification body 311, the hot dry air delivered to the drying device 20 via the first heat exchanger 31 can be purified, removing impurities, particles, etc., thereby improving the quality of the hot dry air, further improving the drying effect and the cleanliness of the workpiece, while also protecting the internal structure of the drying device 20 and extending its service life.

[0057] The working process of the cleaning system 100 described above is roughly as follows:

[0058] First, the dispensing component 14 dispenses hot cleaning liquid to the rinsing component 11 and the spraying component 12. The rinsing component 11 rinses the workpiece with the hot cleaning liquid and discharges the hot waste liquid. The spraying component 12 sprays hot cleaning liquid onto the surface of the rinsed workpiece and discharges the hot waste liquid. The drying component 21 blows hot dry air onto the workpiece to dry the cleaned workpiece and discharges hot humid air. In this way, the cleaning and drying of the workpiece is completed quickly, thereby achieving efficient cleaning and drying of the workpiece.

[0059] Then, the liquid receiving unit 13 collects the hot waste liquid and transports the hot waste liquid to the first heat exchange unit 31, and the air receiving unit 22 collects the hot and humid air and transports the hot and humid air to the second heat exchange unit 33.

[0060] Next, the first heat exchanger 31 lowers the temperature of the hot waste liquid to form room temperature waste liquid, the filter 32 filters the room temperature waste liquid to form room temperature cleaning liquid, and delivers the room temperature cleaning liquid to the second heat exchanger 33. At the same time, the second heat exchanger 33 causes the hot humid air and the room temperature cleaning liquid to exchange heat to form room temperature humid air and hot cleaning liquid, and delivers the room temperature humid air to the condenser 34. The condenser 34 condenses the room temperature humid air to form room temperature dry air, and delivers the room temperature dry air to the first heat exchanger 31, so that the room temperature dry air becomes hot dry air after passing through the first heat exchanger 31.

[0061] Finally, the first heat exchanger 31 delivers hot dry air to the drying unit 21 for recycling, and the second heat exchanger 33 delivers hot cleaning fluid to the distribution unit 14 for recycling. This achieves heat exchange and recycling of the hot waste liquid and hot humid air generated during the workpiece cleaning process, effectively recovering heat, water and air resources, reducing energy waste, and lowering energy consumption and operating costs.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
