Description

Technical Field

[0001] This utility model relates to the field of spray equipment technology, specifically to a spray system for a cleaning machine. Background Technology

[0002] Vacuum hydrocarbon cleaning machines are cleaning equipment used for cleaning precision industrial parts. They utilize hydrocarbon solvents as the cleaning medium, combined with vacuum technology, to perform efficient and environmentally friendly cleaning operations. These machines are widely used for cleaning precision parts, optical instruments, electronic components, and other fields. The working principle of a hydrocarbon solvent vacuum cleaning machine is mainly based on the special properties of the vacuum environment and hydrocarbon solvents to achieve efficient cleaning. In a vacuum environment, the gas pressure decreases, causing the boiling point of the hydrocarbon solvent to also decrease, thus enabling cleaning at a lower temperature. This improves cleaning efficiency while avoiding damage to the items being cleaned due to high temperatures.

[0003] Traditional cleaning machine spray systems typically involve installing spray pipes within the cleaning chamber and connecting them to a cleaning agent storage tank. This allows the cleaning agent from the storage tank to be introduced into the cleaning chamber to complete the cleaning operation. However, after cleaning, some cleaning agent inevitably remains in the spray pipes, resulting in unnecessary waste of the cleaning agent. Furthermore, the agent may deteriorate or contaminate the pipes due to prolonged residue, posing certain safety hazards. Utility Model Content

[0004] In view of this, the present invention provides a spray system for a cleaning machine, which can efficiently discharge residual cleaning agent in the spray pipe, avoid its accumulation in the spray pipe, avoid unnecessary waste of cleaning agent and pollution of the pipe, and is safer and more convenient.

[0005] To solve the above-mentioned technical problems, this utility model provides a spray system for a cleaning machine. The spray system is installed on a cleaning chamber, and a distillation tank and a liquid storage system are connected to the outside of the cleaning chamber. The spray system and the liquid storage system are connected by a pipe and a water pump, which is a spray cleaning pump. The inlet end of the pipe is connected to the outlet end of the liquid storage system, and the outlet end of the pipe is connected to the inlet end of the water pump. The spray system includes a spray inlet main pipe connected to the outlet end of the water pump. The spray inlet main pipe is equipped with a water inlet pipe and an air inlet pipe. The water inlet pipe is connected to the spray system and is used to introduce the cleaning agent discharged from the spray inlet main pipe into the spray system. The air inlet pipe is connected to the outlet of the distillation tank, and the hot gas generated by distillation or the high-temperature cleaning agent evaporated from the distillation tank can be introduced into the spray system through the air inlet pipe, thereby realizing the spray cleaning. After cleaning is completed, any residual cleaning agent is discharged to prevent it from remaining in the spray system. The spray system also includes at least two main spray pipes, each with its inlet connected to the outlet of the main liquid inlet pipe. Each main spray pipe is equipped with multiple branch spray pipes connected to it, and each branch spray pipe has a nozzle connected to it at its end. The nozzles are placed in the cleaning chamber with their openings facing downwards, allowing the nozzles to spray the cleaning agent from the storage system into the cleaning chamber. This invention enables efficient spray cleaning of workpieces in the cleaning chamber through the spray system. The air inlet pipe connected to the distillation tank blows away any residual cleaning agent in the spray pipes, avoiding the unnecessary waste of cleaning agent and potential safety hazards that can easily accumulate in the cleaning pipes of traditional cleaning systems. This makes the system more energy-efficient and safer.

[0006] The liquid storage system includes a coarse washing liquid storage tank and a fine washing liquid storage tank, both of which store cleaning agent.

This invention can pump the cleaning agent in the liquid storage system into the spraying system through the action of the water pump. The opening and closing of the coarse washing liquid storage tank and the fine washing liquid storage tank can be controlled separately through the three-way valve, making it more efficient and convenient.

[0007] A one-way valve is installed on the outlet of the distillation tank and the water inlet pipe connected to it. The one-way valve is a solenoid valve, which controls the heat or high-temperature steam in the distillation tank to be introduced into the spray liquid inlet main pipe through the water inlet pipe. This utility model can use the heat generated by distillation in the distillation tank to flow into the water inlet pipe through the action of the one-way valve to flush out the cleaning agent remaining in the spray liquid inlet main pipe, spray liquid inlet branch pipes and nozzles, avoiding unnecessary waste and secondary pollution caused by residue in the pipeline, making the operation more efficient and convenient.

[0008] The spray branch pipe and the nozzle are connected by a connecting sleeve, which penetrates the side wall of the cleaning chamber. The connection between the connecting sleeve and the cleaning chamber is sealed. An installation hole is provided on the side wall of the cleaning chamber, through which the connecting sleeve passes. A sealing structure is provided between the connecting sleeve and the installation hole, and the connection is sealed with sealant. This utility model can realize the connection between the spray branch pipe and the nozzle through the connecting sleeve, which facilitates the introduction of cleaning agent into the nozzle and its spraying into the cleaning chamber.

[0009] Multiple nozzles on the same spray branch pipe are arranged alternately as positioning nozzles and rotating nozzles.

This is more energy-efficient and safer.

[0020] like Figure 1 and Figure 2 As shown: This embodiment provides a spray system for a cleaning machine. The spray system is installed on a cleaning chamber 100. A distillation tank and a liquid storage system are connected to the outside of the cleaning chamber 100. The spray system and the liquid storage system are connected by a pipe and a water pump. The water pump is a spray cleaning pump, a stainless steel vertical pump with a power of 0.4 MPa / 15 m² / 5.5 kW. The inlet end of the pipe is connected to the outlet end of the liquid storage system, and the outlet end of the pipe is connected to the inlet end of the water pump. The spray system includes a spray nozzle connected to the outlet end of the water pump. The main inlet pipe 200 is equipped with a water inlet pipe 201 and an air inlet pipe 202 connected to it. The outlet of the water inlet pipe 201 is connected to the spray system, used to introduce the cleaning agent discharged from the main inlet pipe 200 into the spray system. The inlet of the air inlet pipe 202 is connected to the outlet of the distillation tank, allowing the hot gas generated during distillation or the high-temperature cleaning agent evaporated from the tank to be introduced into the spray system through the air inlet pipe 202. This ensures that any residual cleaning agent after cleaning is discharged from the spray system, preventing it from remaining within the system. Figure 2As shown, the spray system also includes at least two main spray pipes 300. The inlet of each main spray pipe 300 is connected to the outlet of the main liquid inlet pipe. Each main spray pipe 300 is equipped with multiple spray branch pipes 301 connected to it.

The main spray pipe 300 is also equipped with an oil tap or oil outlet. Its cleanliness meets the level 6 of GJB420B-2015 and GOST standards. The 8th grade of the 17216-71 standard is equipped with a nozzle 302 connected to the end of each spray branch pipe 301. The nozzle 302 can spray the cleaning agent in the liquid storage system into the cleaning chamber 100. The spray main pipe 300 and the spray branch pipe 301 are both made of SUS304. This utility model can achieve efficient spray cleaning of the workpiece in the cleaning chamber 100 through the spray system. The air inlet pipe 202 connected to the distillation tank can blow away the residual cleaning agent in the spray pipe, avoiding the accumulation of liquid in the cleaning pipe of the traditional cleaning system, which causes unnecessary waste of cleaning agent and also brings certain safety hazards. It is more energy-saving and safer.

[0021] According to one embodiment of the present invention, such as Figure 1 As shown, the liquid storage system includes a coarse washing liquid storage tank and a fine washing liquid storage tank. Both the coarse washing liquid storage tank and the fine washing liquid storage tank store cleaning agent. A three-way valve is installed at the inlet of the water pump. The three-way valve is an electrically controlled water valve that is electrically connected to the control system of the cleaning machine. The first port of the three-way valve is connected to the outlet of the coarse washing liquid storage tank, and the second port of the three-way valve is connected to the outlet of the fine washing liquid storage tank. The outlet of the water pump is connected to the inlet of the water inlet pipe 201. This utility model can pump the cleaning agent in the liquid storage system into the spray system through the action of the water pump. The opening and closing of the coarse washing liquid storage tank and the fine washing liquid storage tank can be controlled separately through the three-way valve, thereby realizing the coarse washing and fine washing operations of the workpieces in the cleaning chamber 100, which is more efficient and convenient.

[0022] A one-way valve is installed on the outlet of the distillation tank and the water inlet pipe 201 connected to it. The one-way valve is a solenoid valve, which controls the heat or high-temperature steam in the distillation tank to be introduced into the spray liquid inlet main pipe 200 through the air inlet pipe 202. This utility model can use the heat generated by distillation in the distillation tank to flow into the air inlet pipe 202 through the action of the one-way valve to flush out the cleaning agent remaining in the spray liquid inlet main pipe 200, the spray liquid inlet branch pipes and the nozzles 302, so as to avoid unnecessary waste and secondary pollution caused by its residue in the pipeline.

An installation hole is provided on the side wall of the cleaning chamber 100. The connecting sleeve 400 passes through the installation hole. A sealing structure is provided between the connecting sleeve 400 and the installation hole. The connection is sealed by sealant. This utility model can realize the connection between the spray branch pipe 301 and the nozzle 302 through the connecting sleeve 400, which facilitates the introduction of cleaning agent into the nozzle 302 and spraying it out into the cleaning chamber 100.

[0024] Multiple nozzles 302 on the same spray branch pipe 301 are arranged alternately as positioning nozzles and rotating nozzles. The rotating nozzles are connected to the spray branch pipe 301 through a rotary joint or universal ball joint and are used for rinsing the inner cavity of the components inside the casing.

[0025] How to use this utility model:

[0026] First, it should be clarified that the spray system involved in this utility model is mainly used in hydrocarbon vacuum cleaning machines. It is connected to the cleaning system and the distillation tank through pipelines, and can introduce the cleaning agent in the cleaning system, the vaporized cleaning agent distilled from the distillation tank, and excess heat into the spray system. The various valves and controllers installed on the pipelines are all existing finished products, and there is no need to limit their specific models here, only their functions. If the user has special requirements for the models, as long as they can meet the requirements of cleanliness and stable system operation, they can be adapted and adjusted. Since this application focuses on the discharge of residual cleaning agent in the spray system as the core modification point, the principle and usage method are described in detail with this as the focus. When it is necessary to clean the workpiece, the following steps should be followed:

[0027] Rough cleaning process: Start the water pump motor to rotate forward, and simultaneously start the three-way valve to open the branch pipe connected to the rough cleaning tank and close the branch pipe connected to the fine cleaning tank. Then the water pump can draw the hydrocarbon solution from the rough cleaning tank. The rough cleaning liquid flows into the spray inlet main pipe 200 and is sprayed out through the spray branch pipe 301 and nozzle 302 to spray and clean the workpiece. After the specified time is reached, start the water pump motor to rotate in reverse. At this time, the water pump will draw the hydrocarbon cleaning agent solution after rough cleaning in the cleaning chamber 100. The hydrocarbon cleaning agent solution after rough cleaning is filtered again by the filter and flows into the cleaning chamber 100 for circulation cleaning until the rough cleaning is completed. Then the water pump continues to work until the rough cleaning liquid in the cleaning chamber 100 is drawn into the distillation tank. At this time, the rough cleaning liquid in the cleaning chamber 100 is emptied.

[0028] Fine cleaning process: Start the water pump motor to rotate forward, and at the same time start the three-way valve to close the branch pipe connected to the rough cleaning tank and open the branch pipe connected to the fine cleaning tank. Then the water pump can draw the hydrocarbon solution from the fine cleaning tank and the fine cleaning liquid flows into the spray inlet main pipe 200 to spray clean the workpiece. After the specified time is reached, start the water pump motor to rotate in reverse. At this time, the water pump will draw the finely cleaned hydrocarbon cleaning agent solution in the cleaning chamber 100. The finely cleaned hydrocarbon cleaning agent solution is filtered again by the filter and flows into the cleaning chamber 100 for circulation cleaning until the fine cleaning is completed.

[0029] Discharge of residual cleaning agent in the spray system: After the fine cleaning is completed, the one-way valve is opened, and the pure hydrocarbon vapor produced by distillation in the distillation tank is also drawn into the cleaning chamber 100 by the air pump. When the steam passes through the spray liquid inlet main pipe 200, the steam blows away the residual liquid in the spray liquid inlet main pipe 200, thereby achieving efficient discharge of residual cleaning agent in the spray system. This utility model can use the heat generated by distillation in the distillation tank to be introduced into the air inlet pipe 202 through the action of the one-way valve to flush out the residual cleaning agent in the spray liquid inlet main pipe 200, the spray liquid inlet branch pipe and the nozzle 302, avoiding unnecessary waste and secondary pollution caused by its residue in the pipeline, making the operation safer and more convenient.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
