[0017] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0018] Please refer to Figure 1 A vacuum energy-saving and environmentally friendly system 100 for removing impurities includes: multiple branch line components 1, a trunk pipe 2, a filtering device 3 and a vacuum pump 4.

[0019] Multiple branch line components 1 are distributed in sequence along the extension direction of the main pipe 2 to form multiple working branches. Each branch line component 1 includes a branch line pipe 11, an air pressure detection control device 12 and a suction device 13. The air pressure detection control device 12 is connected to the side of the main pipe 2 and the suction device 13 through the branch line pipe 11 respectively.

[0020] The filter device 3 and the vacuum pump 4 are sequentially connected to the trunk pipe 2 . The air inlet side of the filter device 3 is connected to the multiple branch line components 1 through the trunk pipe 2 , and the air outlet side of the filter device 3 is connected to the vacuum pump 4 through the trunk pipe 2 .

[0021] Among them, in any working branch, when the air pressure detection control device 12 detects that the branch line vacuum pressure in the corresponding branch line pipe 11 is higher than the first preset vacuum pressure value, the air pressure detection control device 12 issues an alarm; when the air pressure detection control device 12 detects that the branch line vacuum pressure of the corresponding branch line pipe 11 is not higher than the first preset vacuum pressure value, the air pressure detection control device 12 turns off the alarm; when the air pressure detection control device 12 detects that the branch line vacuum pressure of the corresponding branch line pipe 11 is higher than the second preset vacuum pressure value, the air pressure detection control device 12 automatically closes the corresponding branch line pipe 11, and the second preset vacuum pressure value is higher than the first preset vacuum pressure value.

[0022] Optionally, the air pressure detection control device 12 includes an on-off solenoid valve 121, an electrical control box 122, an air pressure detector 123 and a pressure alarm 124. The on-off solenoid valve 121 is connected to the branch pipe 11 for controlling the on and off of the branch pipe 11. The electrical control box 122 is electrically connected to the on-off solenoid valve 121 and the pressure alarm 124 respectively. The air pressure detector 123 is connected to the side of the branch pipe 11, and the air pressure detector 123 is electrically connected to the electrical control box 122. It is used to detect the branch line vacuum pressure of the corresponding branch pipe 11 in real time, and then control the opening and closing of the on-off solenoid valve 121 and the pressure alarm 124 through the electrical control box 122.

[0023] Preferably, when the air pressure detector 123 detects that the branch line vacuum pressure is higher than the first preset vacuum pressure value, the air pressure detector 123 sends a signal to the electrical control box 122 to control the pressure alarm 124 to issue an alarm. When the air pressure detector 123 detects that the branch line vacuum pressure is not higher than the first preset vacuum pressure value, the air pressure detector 123 sends a signal to the electrical control box 122 to control the pressure alarm 124 to turn off the alarm. When the air pressure detector 123 detects that the branch line vacuum pressure is higher than the second preset vacuum pressure value, the air pressure detector 123 sends a signal to the electrical control box 122 to control the on-off solenoid valve 121 to close the branch pipe 11.

[0024] Preferably, the air pressure detector 123 includes a pressure signal processing module, which is used to set a first preset vacuum pressure value and a second preset vacuum pressure value, and to send a control signal to the electrical control box 122 when the first preset vacuum pressure value and the second preset vacuum pressure value are reached. Using such an integrated pressure signal processing module in the air pressure detector 123 is more cost-effective than installing a central control unit in the electrical control box 122.

[0025] Preferably, the air pressure detector 123 adopts a digital display pressure sensor, which is arranged on the outside of the electrical control box 122. In this way, it can not only process the pressure signal but also display the pressure in real time.

[0026] Preferably, the electrical control box 122 also includes a manual switch for manually controlling the power supply within the electrical control box 122, the opening and closing of the on-off solenoid valve 121, and the deactivation of the pressure alarm 124. This facilitates the startup of the electrical control box and allows the branch pipes to resume operation after an obstacle is removed. In addition, the on-off solenoid valve 121 can be closed when maintenance is required.

[0027] Preferably, the manual switch is located outside the electrical control box 122. The manual switch includes a run button, an alarm off button, and a solenoid valve on-off button. The run button controls the power on and off in the electrical control box, the alarm off button is used to control the alarm to turn off the alarm, and the solenoid valve on-off button is used to control the on-off solenoid valve to close and open the branch pipe 11. This makes operation more convenient and can be controlled without opening the electrical control box 122.

[0028] Optionally, each branch pipe 11 is vertically connected to the side of the main pipe 2. This arrangement shortens the connection distance.

[0029] Optionally, the filtering device 3 includes a coarse filtering tank 31 and a fine filtering tank 32, and the fine filtering tank is connected to the coarse filtering tank and the vacuum pump 4 through the trunk line 2. This arrangement facilitates better filtration.

[0030] The operating principle of the vacuum energy-saving and environmentally friendly system 100 for removing impurities according to one embodiment of the present invention is as follows:

[0031] During normal impurity removal, the impurities and water vapor in the raw materials processed on each processing equipment are sucked into the corresponding working branches through the suction device 13 under the suction action of the vacuum pump 4, and then enter the main pipe 2 after passing through the branch pipe 11 and the air pressure detection control device 12. Then the filter device 3 filters out the waste liquid and impurities therein, and the remaining clean gas is sucked into the vacuum pump 4 and discharged normally.

[0032] During any working branch, when the air pressure detection control device 12 detects that the branch line vacuum pressure in the corresponding branch pipe 11 is higher than the first preset vacuum pressure value, the air pressure detection control device 12 will issue an alarm to facilitate the staff to check the situation in time. When the air pressure detection control device 12 detects that the branch line vacuum pressure of the corresponding branch pipe 11 is not higher than the first preset vacuum pressure value, the air pressure detection control device 12 turns off the alarm. When the air pressure detection control device 12 detects that the branch line vacuum pressure of the corresponding branch pipe 11 is higher than the second preset vacuum pressure value, the air pressure detection control device 12 automatically closes the corresponding branch pipe 11. In this way, when some working branches are abnormal, it will not affect the cleaning work of other normal working branches. In addition, when a processing equipment needs to be shut down for maintenance, the branch pipe 11 of the corresponding working branch can also be closed separately.

[0033] The vacuum energy-saving and environmentally friendly system for impurity removal of the utility model can remove impurities from the processing raw materials of multiple processing equipment at the same time, can also be used at different times to improve utilization efficiency, and can also achieve environmentally friendly emissions, greatly saving energy and operating costs, and effectively improving the quality of processed products.

[0034] The present invention has been described with reference to the above embodiments. However, these embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
