DETAILED DESCRIPTION

[0054] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0055] At present, in order to clean the device of the vacuum pump, gas or water is usually used for cleaning, which cannot effectively clean the solid waste. For solid waste, the vacuum pump and other devices need to be disassembled manually, and a scraper and other devices are used for cleaning.

[0056] In order to solve the above problems, the present application provides a cleaning device, which is connected with the vacuum pump and other waiting cleaning pieces, can clean the solidified waste in the waiting cleaning piece, effectively reduces the required cleaning time through the multi-round cleaning device structure, improves the overall cleaning efficiency, optimizes the overall cleaning effect, is suitable for cleaning a plurality of different types of waiting cleaning pieces, and meets the cleaning demand of the waiting cleaning piece in a plurality of different processing scenes.

[0057] Please refer to Figure 1 , Figure 1 The structure diagram of the cleaning device provided in the embodiments of the present application can include: a liquid cleaning assembly 100, a gas cleaning assembly 200, a cleaning pipeline 300 and a connector 400.

[0058] The liquid cleaning assembly 100 and the gas cleaning assembly 200 are connected with the cleaning pipeline 300, and the cleaning pipeline 300 is connected with the inlet pipeline A1 of the to-be-cleaned component A outside through the connecting piece 400. The cleaning pipeline 300 is used for transmitting the liquid in the liquid cleaning assembly 100 into the to-be-cleaned component A through the connecting piece 400. The cleaning device is provided with the liquid cleaning assembly 100 for providing the liquid for cleaning and the gas cleaning assembly 200 for providing the gas for cleaning, and the cleaning pipeline 300 connected with the liquid cleaning assembly 100 and the gas cleaning assembly 200. The cleaning pipeline 300 is also used for transmitting the gas in the gas cleaning assembly 200 into the to-be-cleaned component A through the connecting piece 400. The cleaning pipeline 300 is connected with the inlet pipeline A1 of the to-be-cleaned component A outside through the corresponding connecting piece 400, so as to transmit the liquid in the liquid cleaning assembly 100 and the gas in the gas cleaning assembly 200 into the to-be-cleaned component A. The solidified waste in the to-be-cleaned component A is dissolved by the cleaning agent, the softened waste is flushed by the flushing liquid, and the flushed to-be-cleaned component A is dried and cleaned by the gas.

[0059] It should be noted that the liquid can include various types and concentrations of cleaning agents and flushing liquids. The cleaning agent can include various types of acidic or alkaline cleaning agents, such as inorganic acid, organic acid, or acidic or alkaline cleaning agents that can be similar to the waste in the to-be-cleaned component A and produce emulsion. The flushing liquid can include water, alcohol, water-containing alcohol, and other liquid media with flushing function to flush the waste dissolved by the cleaning agent.

[0060] Optionally, the composition of the waste in the to-be-cleaned component A can be determined according to the working process of the to-be-cleaned component A, and one or more appropriate cleaning agents with corresponding concentrations can be selected for cleaning according to the material of the to-be-cleaned component A.

[0061] Optionally, the gas in the gas cleaning assembly 200 can include nitrogen and other inert gases that are not easy to react with the waste and have relatively stable chemical properties, so that the nitrogen gas in the cleaning pipeline 300 is used for air drying and drying.

[0062] For example, the liquid cleaning assembly 100, the gas cleaning assembly 200, the cleaning pipeline 300, and the connecting piece 400 can be made of corresponding metal or plastic materials to reduce the reaction between the liquid, the gas, and the device, thereby reducing the adverse effects of material reaction on the cleaning device.

[0063] Optionally, the cleaning device can be in communication connection with a corresponding electronic device, and the electronic device can be a server, a personal computer (PC), a tablet computer, a smart phone, a personal digital assistant (PDA) or the like electronic device having a logic computing function. The cleaning device can acquire a control signal generated in the electronic device, and control the corresponding liquid cleaning assembly 100 or gas cleaning assembly to work in response to the control signal, so as to realize various types of cleaning processing.

[0064] In Figure 1 In the embodiment shown, the waste material solidified in the cleaning object A can be subjected to cleaning processing, and the device structure of multiple rounds of cleaning effectively reduces the required cleaning time, improves the overall cleaning efficiency, optimizes the overall cleaning effect, and is suitable for cleaning processing of various types of cleaning objects A, and meets the cleaning needs of the cleaning objects A in various processing scenarios.

[0065] Optionally, referring to Figure 2 , Figure 2 A specific structure diagram of a cleaning device provided by the embodiment of the present application is shown, wherein the liquid cleaning assembly 100 can include one or more cleaning agent branches 110. Each cleaning agent branch 110 can include a cleaning agent filling port, a cleaning agent container 112, a first switch valve 113 and a pressure valve 114.

[0066] The first end of the cleaning agent container 112 is connected with the cleaning agent filling port, the second end of the cleaning agent container 112 is connected with the cleaning pipeline 300 through the first switch valve 113, the pressure valve 114 is connected with the cleaning agent container 112, and the pressure valve 114 is used for providing the outlet liquid pressure in the cleaning agent container 112. The liquid cleaning assembly 100 can include one or more cleaning agent branches 110, each of which includes a cleaning agent filling port for filling cleaning agent and a cleaning agent container 112 for storing cleaning agent, so as to realize automatic filling and long-term storage of cleaning agent. In addition, the first switch valve 113 and the pressure valve 114 connected with the cleaning agent container 112 can be provided, so that the cleaning agent is injected into the cleaning pipeline 300 connected with the cleaning agent branch 110 through the opening of the first switch valve 113, the cleaning agent is transmitted into the cleaning pipeline 300 to clean the cleaning object A, the injection of the cleaning agent is stopped through the closing of the first switch valve 113, and the automatic cleaning process of the cleaning agent to the cleaning object A is realized. The pressure valve 114 can provide the outlet liquid pressure in the cleaning agent container 112, so that the stable output of the cleaning agent is realized through the stable outlet liquid pressure in the case that the first switch valve 113 is opened, and the stability and effectiveness of the cleaning agent branch 110 providing the cleaning agent to the cleaning pipeline 300 are effectively improved, so as to improve the efficiency of cleaning by using the cleaning agent and optimize the effect of cleaning by using the cleaning agent.

[0067] Optionally, Figure 2 Only one feasible implementation structure with two cleaning agent branches 110 is shown, and the structures of other numbers of cleaning agent branches 110 will not be described in detail.

[0068] It should be noted that in the placement direction of the cleaning agent container 112, the first end of the cleaning agent container 112 can be the top end, and the first end can be provided with a corresponding opening to be connected with the cleaning agent filling port. The second end of the cleaning agent container 112 can be the bottom end, and the second end can be provided with a corresponding liquid outlet. The cleaning agent filling port can be arranged at the top end of the cleaning agent container 112, and the other end of the cleaning agent filling port can be connected with a corresponding liquid inlet pipeline to obtain the corresponding cleaning agent and inject the cleaning agent into the cleaning agent container 112 by using the principle of gravity, so that the cleaning agent flows from the cleaning agent container 112 into the cleaning pipeline 300.

[0069] For example, the cleaning agent filling port can be arranged as a corresponding funnel or the like component, so that the cleaning agent can accurately flow into the cleaning agent container 112.

[0070] Optionally, the pressure valve 114 can be set as a corresponding back pressure valve or the like device, and the pressure valve 114 can also be connected with the first end of the cleaning agent container 112. For example, nitrogen can be injected into the cleaning agent container 112 through the pressure valve 114 and maintained at 3-5 bar pressure, so that the cleaning agent in the cleaning agent container 112 can flow into the cleaning pipeline 300 stably and uniformly under the stable pressure. Since the pressure valve 114 can provide stable liquid outlet pressure, the opening time of the first on-off valve 113 in the cleaning agent branch 110 has a stable linear relationship with the dose of the cleaning agent.

[0071] For example, the cleaning agent container 112 can be set as a corresponding metal material or plastic material which does not react with the cleaning agent stored therein. In addition, the shape and size of the cleaning agent container 112 can be designed according to the actual situation of the to-be-cleaned object A, such as the size of the pipeline to be cleaned in the to-be-cleaned object A, the waste condition, and the like. For example, a cylindrical container with a capacity of 50L can be designed.

[0072] Optionally, the electronic device can determine a corresponding cleaning program according to the test data of the to-be-cleaned object A, and generate a plurality of control signals according to the cleaning program. The first on-off valve 113 can be set as a control valve device capable of being automatically opened or closed according to the control signals.

[0073] It should be noted that, in order to ensure that the cleaning agent container 112 always has sufficient cleaning agent to clean the to-be-cleaned object A, the cleaning agent branch 110 can further include a low liquid level meter 115 connected with the cleaning agent container 112 and the cleaning agent filling port. The low liquid level meter 115 is used to determine a low liquid level signal of the cleaning agent in the cleaning agent container 112. The low liquid level meter 115 connected with the cleaning agent container 112 can determine the low liquid level signal when the cleaning agent in the cleaning agent container 112 is low, and based on the connection between the low liquid level meter 115 and the cleaning agent filling port, the opening of the cleaning agent filling port can be controlled by the low liquid level signal, so that the cleaning agent can be automatically supplemented when the amount of cleaning agent in the cleaning agent container 112 is low. The amount of cleaning agent does not need to be observed and manually supplemented, which reduces the adverse conditions such as the inability to clean due to the depletion of cleaning agent or the suspension of liquid supplementing during the cleaning process due to the depletion of cleaning agent. The automatic liquid supplementing process can be realized when the amount of cleaning agent is low, which effectively improves the efficiency and stability of the cleaning process using the cleaning agent.

[0074] Optionally, the low liquid level meter 115 can also be connected with the electronic device to transmit the low liquid level signal to the electronic device, and the electronic device can generate a corresponding control signal to control the opening of the cleaning agent filling port to realize the liquid supplementing process.

[0075] It should be noted that, in order to prevent the cleaning agent in the cleaning agent container 112 from overflowing and other adverse situations, the cleaning agent branch 110 can further include a high liquid level meter 116 connected to the cleaning agent container 112 and the cleaning agent filling port, which is used to determine the high liquid level signal of the cleaning agent in the cleaning agent container 112. The high liquid level meter 116 connected to the cleaning agent container 112 can be provided, and the high liquid level signal of the cleaning agent in the cleaning agent container 112 can be determined by the high liquid level meter 116. Based on the connection between the high liquid level meter 116 and the cleaning agent filling port, the closing of the cleaning agent filling port is controlled by the high liquid level signal, so that the replenishment process of the cleaning agent is automatically stopped when the amount of cleaning agent in the cleaning agent container 112 is sufficient, without the need for manual observation and manual stop of the replenishment of the cleaning agent, reducing the adverse situation caused by the overflow of the cleaning agent from the cleaning agent container 112, and automatically stopping the replenishment process when the amount of cleaning agent is sufficient, effectively improving the efficiency and stability of the cleaning process using the cleaning agent.

[0076] Optionally, the high liquid level meter 116 can also be connected to the electronic device to transmit the high liquid level signal to the electronic device, and the electronic device can generate a corresponding control signal to control the cleaning agent filling port to close and stop the replenishment process.

[0077] It should be noted that the low liquid level meter 115 is arranged at the second end of the cleaning agent container 112 close to the cleaning pipeline 300, and the high liquid level meter 116 is arranged at the first end of the cleaning agent container 112 close to the cleaning agent filling port. The specific detection positions of the low liquid level meter 115 and the high liquid level meter 116 can be set according to the actual capacity, etc. For example, when the cleaning agent container 112 is 50L, the low liquid level meter 115 can be arranged at the position of 5L of the cleaning agent, and the high liquid level meter 116 can be arranged at the position of 48L of the cleaning agent, etc.

[0078] It should be noted that, in the case that the liquid cleaning assembly 100 includes a plurality of cleaning agent branches 110, different types of cleaning agents can be stored in the plurality of cleaning agent containers 112, for example, a corresponding concentration of hydrochloric acid solution is arranged in the first cleaning agent container 112 of the first cleaning agent branch 110 to corrode the aluminum metal waste in the to-be-cleaned part A, and a corresponding concentration of sodium hydroxide solution is arranged in the second cleaning agent container 112 of the second cleaning agent branch 110 to dissolve the oil waste in the to-be-cleaned part A, etc.

[0079] Optionally, considering the difference in the order of use of different types of cleaning agents in the cleaning process of the cleaning agent, the plurality of first switch valves 113 can be opened and closed in a predetermined order, and the opening time of each first switch valve 113 is determined based on the waste in the to-be-cleaned part A.

[0080] For example, the preset cleaning program in the electronic device can be provided with a preset sequence of the plurality of cleaning agent branches 110, so as to open and close the first switch valve 113 in each cleaning agent branch 110 in the preset sequence, thereby respectively controlling the plurality of different cleaning agent branches 110 to work. Moreover, considering the difference in loss amount required by the plurality of different types of cleaning agents, the opening time of each first switch valve 113 can be determined according to the type, volume, etc. of the waste in the piece A to be cleaned. For example, the piece A to be cleaned contains aluminum metal waste and oil waste, in which the aluminum metal waste is more and the oil waste is less, so the first cleaning agent branch 110 can be opened first, the opening time of the first switch valve 113 of the first cleaning agent branch 110 is 10 seconds, the second cleaning agent branch 110 is opened after the first cleaning agent branch 110 is cleaned, and the opening time of the second cleaning agent branch 110 is 5 seconds, etc. In this way, the plurality of different types of cleaning agents with different loss amounts are used in turn for multiple cleaning processes, the speed and effect of the cleaning agent in dissolving the waste in the piece A to be cleaned are effectively improved through multiple cleaning, and the cleaning effect of the cleaning agent is optimized.

[0081] Optionally, the connecting piece 400 can be provided as a three-way piece, such as a flange of an air inlet three-way, etc. The first end of the three-way piece is connected with the cleaning pipeline 300, the second end of the three-way piece is connected with the inlet pipeline A1 of the piece A to be cleaned, and the third end of the three-way piece is connected with the process chamber of the piece A to be cleaned. The first end of the three-way piece is connected with the cleaning pipeline 300, the second end is connected with the inlet pipeline A1 of the piece A to be cleaned, and the third end is connected with the process chamber of the piece A to be cleaned, so as to realize the corresponding working function and cleaning function of the piece A to be cleaned.

[0082] Moreover, in the case that the inlet pipeline A1 of the piece A to be cleaned is connected with the process chamber through the three-way piece, the first end of the three-way piece is closed, the cleaning piece is in communication with the process chamber for normal work, and in order not to affect the normal work of the piece A to be cleaned, the first end of the three-way piece is closed, i.e. the cleaning path of the cleaning pipeline 300 is closed, so that the cleaning device does not affect the normal working process of the piece A to be cleaned. In the case that the inlet pipeline A1 of the piece A to be cleaned is connected with the cleaning pipeline 300 through the three-way piece, the third end of the three-way piece is closed, and in the case that the inlet pipeline A1 of the piece A to be cleaned is connected with the cleaning pipeline 300 through the three-way piece, the third end of the three-way piece is closed, so as to realize the cleaning function in the case that the piece A to be cleaned does not work. The piece A to be cleaned can be cleaned online without affecting the normal work of the piece A to be cleaned, and the piece A to be cleaned does not need to be disassembled and cleaned, thereby effectively improving the efficiency and reliability of the cleaning process.

[0083] Optionally, the to-be-cleaned component A can be connected to an external processing device through the process chamber, such as a vacuumized device, and the process operation of the to-be-cleaned component A can include a process treatment such as a de-esterification sintering.

[0084] Optionally, considering the influence of temperature on the cleaning effect, the cleaning device can further include a heating assembly connected to the cleaning pipeline 300 and the connecting component 400, and the heating assembly is used to heat the liquid and / or gas flowing through the cleaning pipeline 300 and the connecting component 400. The heating assembly is connected to the cleaning pipeline 300 and the connecting component 400 to heat the cleaning pipeline 300 and the connecting component 400, so as to heat the liquid and / or gas flowing through the cleaning pipeline 300 and the connecting component 400. By increasing the temperature of the liquid and / or gas, the cleaning effect of the cleaning device on the cleaning, flushing, drying and other cleaning processes of the to-be-cleaned component A is further optimized.

[0085] For example, the heating assembly can be arranged on the outer wall of the cleaning pipeline 300 and the tee component, and the heating assembly can be a device with a heating function such as a heating resistor. The heating assembly can be communicatively connected to an electronic device to start or stop the heating operation in response to a control signal in the cleaning program.

[0086] Optionally, in order to process the waste material cleaned out of the to-be-cleaned component A, the cleaning device can further include a waste discharge assembly 500 arranged on the outlet pipeline A2 of the to-be-cleaned component A, and the waste discharge assembly 500 is used to transport the waste material discharged from the to-be-cleaned component A. The waste material can be transported and subsequently processed without affecting the normal operation of the to-be-cleaned component A, reducing the adverse effects of the waste material on the outlet pipeline A2 of the to-be-cleaned component A, and realizing a complete waste cleaning and processing process.

[0087] For example, the outlet pipeline A2 of the to-be-cleaned component A can be a process-related exhaust pipe, and the waste discharge assembly 500 can be provided with a corresponding waste discharge valve and a waste discharge pipeline. When the exhaust pipe of the to-be-cleaned component A is in a normal process, the waste discharge valve is closed to reduce the adverse effects on the normal operation of the to-be-cleaned component A. When the exhaust pipe of the to-be-cleaned component A is not working, the waste discharge valve is opened to realize the corresponding waste cleaning and processing through the opening or closing of the waste discharge valve.

[0088] It should be noted that the liquid cleaning assembly 100 can include a flushing liquid branch 120, which can include a liquid inlet 121 and a second switch valve 122, the liquid inlet 121 is connected with the cleaning pipeline 300 through the second switch valve 122, so as to control the communication between the liquid inlet 121 and the cleaning pipeline 300 through the opening and closing of the second switch valve 122, and realize the cleaning process of the flushing liquid to the cleaning object A. The gas cleaning assembly 200 can include a gas inlet 211 and a third switch valve 212, the gas inlet 211 is connected with the cleaning pipeline 300 through the third switch valve 212, so as to control the communication between the gas inlet 211 and the cleaning pipeline 300 through the opening and closing of the third switch valve 212, and realize the cleaning process of the gas to the cleaning object A. The valves are arranged to control the entry of the flushing liquid and the gas into the cleaning pipeline, so as to realize various types of cleaning processing according to various cleaning requirements, and effectively optimize the cleaning effect of the cleaning device to the cleaning object A.

[0089] Optionally, when each cleaning agent branch 110 completes the work, the flushing liquid branch 120 and the gas cleaning assembly 200 can be opened in sequence to reduce the chemical reaction between different cleaning agents, and the residual liquid or residue in the cleaning object A can be discharged through the flushing liquid.

[0090] For example, the cleaning device can perform cleaning processing in a non-working state of the vacuum pump, and in the non-working state, the vacuum pump can rotate at a low speed to further optimize the waste cleaning effect, for example, after the cleaning program starts, the rotation speed of the vacuum pump is reduced from 6000 rpm in the working state to 600 rpm.

[0091] For example, the cleaning program can include: when the main process stage of the device to be cleaned to which the cleaning object A is connected is completed, the cleaning object A enters the shutdown stage, and the shutdown program is started, the rotation speed of the vacuum pump is reduced to about 600 rpm, the cleaning agent filling port 111 in the cleaning agent branch 110 is closed, and the pressure valve 114 is opened.

[0092] The first cleaning process: the first switch valve 113 of the first cleaning agent branch 110 is opened, and is closed after 10s; the vacuum pump continues to operate for about 20s, the second switch valve 122 in the flushing liquid branch 120 is opened, and is closed after 3s; the vacuum pump continues to operate for about 20s, the second switch valve 122 in the flushing liquid branch 120 is opened, and is closed after 3s; the vacuum pump continues to operate for about 20s, the first switch valve 113 of the second cleaning agent branch 110 is opened, and is closed after 5s; the vacuum pump continues to operate for about 20s, the second switch valve 122 in the flushing liquid branch 120 is opened, and is closed after 3s; the vacuum pump continues to operate for about 20s. Among them, the flushing liquid is used for flushing between the two types of cleaning agents, so as to reduce the chemical reaction between the cleaning agents, and the residual liquid or residue is discharged through the flushing liquid.

[0093] The second round of cleaning process: the procedure is similar to the first round of cleaning procedure. The Nth round of cleaning procedure: the procedure is similar to the first round of cleaning procedure until the vacuum pump completes the cleaning process. It should be noted that the number of rounds of cleaning process can be set in advance according to the program verification work of the vacuum pump, for example, according to the process condition, test condition and detection condition of the vacuum pump, and in the case of changing the process, the program verification work needs to be re-performed to effectively optimize the cleaning effect through multiple rounds of cleaning process and realize batch, continuous and stable cleaning work.

[0094] Drying process: open the third switch valve 212 in the gas cleaning branch, and close after 30 min.

[0095] It should be noted that, Figure 2 The flow direction of various liquids, gases and waste materials is also marked in the figure to facilitate understanding of the cleaning process.
