[0002] The waste liquid discharge device usually refers to a waste liquid treatment equipment, and is widely used in many fields such as pharmaceutical, chemical, environmental monitoring and other industries. Among them, a large amount of waste water and waste liquid will be generated in the production process of the circuit board factory, if these waste water and waste liquid are not properly treated, not only the environment will be polluted, but also the valuable resources will be wasted. Therefore, it is very important to regularly recycle and treat the waste water and waste liquid. By using the waste liquid discharge device, the waste liquid can be effectively treated, and the environment and human health can be protected.

[0003] The waste liquid is usually collected into a waste liquid pool first, and then treated through a recovery and purification system after a certain amount is collected, the waste liquid pool needs to be cleaned regularly to prevent too much pollutants from accumulating and affecting the waste liquid treatment effect, the waste liquid discharge device of the existing waste liquid pool has the following defects:

[0004] 1. The degree of automation is low, and manual operation of the valve body is frequently required to control the discharge of waste liquid and waste water. This not only increases the labor intensity of the operator, but also may cause inaccurate or untimely discharge due to improper operation, thereby affecting the production efficiency and environmental protection effect.

[0005] 2. The existing device usually has only one discharge pipeline, whether the waste liquid generated during production or the waste water generated when cleaning the waste liquid pool, is discharged through the same pipeline. This not only increases the risk of pipeline blockage, but also may cause poor treatment effect of the recovery system due to the mixing of waste liquid and waste water. In particular, the waste water generated when cleaning the waste liquid pool often contains a lot of impurities and cleaning agent residues, if the same set of recovery system is used for production waste liquid, it may adversely affect the treatment capacity and effect of the recovery system.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. Figs. 1-3 The automatic waste water and waste liquid discharge device of the utility model will be described in detail as follows:

[0024] The automatic waste liquid and waste water discharging device comprises a waste liquid pool 1 for temporarily storing waste liquid generated during production, a sewage outlet provided at the bottom of the waste liquid pool 1, a sewage pipe 2 connected to the sewage outlet, a controller 3, a flow divider 4 provided at the end of the sewage pipe 2 away from the waste liquid pool 1, two liquid outlets provided on the valve of the flow divider 4, a waste liquid valve 5 and a waste water valve 6 connected to the two liquid outlets respectively, a waste liquid discharge pipe 7 connected to a waste liquid recovery and purification system in the factory at the end of the waste liquid valve 5 away from the waste liquid pool 1, a waste water recovery pool 9 connected to a waste water purification system in the factory through a waste water discharge pipe 8 at the end of the waste water valve 6 away from the waste liquid pool 1, two liquid level sensors 10 provided on the inner wall of the waste liquid pool 1 for detecting the liquid level of the waste liquid and the waste water in the waste liquid pool 1 respectively, the waste liquid valve 5, the waste water valve 6 and the two liquid level sensors 10 being connected to the controller 3, and the waste liquid valve 5 or the waste water valve 6 being opened to discharge liquid when the liquid in the waste liquid pool 1 submerges the liquid level sensors 10.

[0025] The automatic opening and closing control of the waste liquid valve 5, the waste water valve 6, the waste water pump 11 and the waste liquid pump 12 is realized through the controller 3, and manual frequent operation of the valve body and the pump body is not required. This improvement not only significantly reduces the labor intensity of the operators, but also avoids the problems of inaccurate or untimely discharge caused by improper manual operation, thereby improving the production efficiency and the environmental protection effect.

[0026] The flow divider 4 and the two liquid outlets thereof provided in the device are connected to the waste liquid valve 5 and the waste water valve 6 respectively, realizing the separate discharge of the waste liquid and the waste water. This design avoids the risk of pipeline blockage caused by the discharge of the waste liquid and the waste water through the same pipeline, and also prevents the adverse effects of the mixture of the waste liquid and the waste water on the treatment capacity of the recovery system. In particular, the waste water generated during the cleaning of the waste liquid pool 1 contains more impurities and cleaning agent residues, and is treated through the separate waste water recovery pool 9 and the waste water purification system, which can more effectively protect the treatment capacity of the recovery system and improve the resource recovery rate.

[0027] The waste liquid pool 1 is provided with a spray head 14 for cleaning the inner wall of the waste liquid pool 1. The spray head 14 is connected with a cleaning valve and a tap water system cleaning liquid configuration box. The spray head 14 is arranged in the waste liquid pool 1 through a lifting assembly. The lifting assembly includes a fixing frame 15 and a lifting rod 16. The spray head 14 is arranged on the lifting rod 16. A driving motor 17 and a driving screw 18 are arranged in the fixing frame 15. The driving motor 17 is used to drive the driving screw 18 to rotate. The lifting rod 16 is connected with the driving screw 18 through a positioning sleeve 19. The driving screw 18 rotates to make the positioning sleeve 19 move up and down in the fixing frame 15. A guide rod 21 is arranged in the fixing frame 15. The fixing frame 15 is parallel with the driving screw 18. One end of the lifting rod 16 is connected with the driving screw 18 through the positioning sleeve 19. The other end of the lifting rod 16 is connected with the guide rod 21 through a sliding sleeve 20. The inner wall of the waste liquid pool 1 is cleaned by the spray head 14. The lifting adjustment of the spray head 14 is realized through the lifting assembly. It is ensured that the spray head 14 can spray cleaning liquid to each place of the inner wall of the waste liquid pool 1. The dirt and residues on the inner wall of the waste liquid pool 1 are effectively removed. The cleaning effect of the waste liquid pool 1 is improved. Four spray heads 14 are arranged on the lifting rod 16. The spray heads 14 are distributed around the axis of the lifting rod 16. The plurality of spray heads 14 work simultaneously. The dirt and residues can be quickly removed. The cleaning time is shortened. It is ensured that the cleaning liquid is uniformly covered on the inner wall of the waste liquid pool 1.

[0028] The cleaning process is as follows. The driving motor 17 and the cleaning valve are opened through the controller 3. The spray head 14 sprays cleaning liquid. The driving motor 17 makes the lifting rod 16 move up and down in the waste liquid pool 1. The spray head 14 uniformly sprays cleaning liquid on the inner wall of the waste liquid pool 1. Then the spray head 14 is connected with the tap water system through the cleaning valve. The spray head 14 sprays clean water to flush the inner wall of the waste liquid pool 1. When the cleaned waste liquid submerges the liquid level sensor 10 for detecting the liquid level of the waste liquid in the waste liquid pool 1, the controller 3 opens the drainage liquid valve and the drainage pump 11 to drain the waste liquid.

[0029] The liquid drainage principle is as follows. The waste liquid generated in the production process is collected through the waste liquid pool 1. When the waste liquid submerges the liquid level sensor 10 for detecting the liquid level of the waste liquid in the waste liquid pool 1, the liquid level sensor 10 sends an electric signal to the controller 3. The controller 3 opens the waste liquid drainage valve 5 and the waste liquid drainage pump 12. The waste liquid flows to the waste liquid recycling and purification system in the factory through the waste liquid drainage pipe 7. The water flow sensor 13 sends an electric signal to the controller 3 after detecting that the waste liquid is drained. The controller 3 closes the waste liquid drainage valve 5 and the waste liquid drainage pump 12. The waste liquid pool 1 is cleaned. The waste liquid drainage valve 5 and the waste liquid drainage valve 6 are closed during the cleaning process. When the cleaning liquid submerges the liquid level sensor 10 for detecting the liquid level of the waste liquid in the waste liquid pool 1, the liquid level sensor 10 sends an electric signal to the controller 3. The controller 3 opens the drainage liquid valve and the drainage pump 11. The waste liquid flows to the waste liquid recycling pool 9 through the drainage pipe 8 to wait for recycling and treatment.

The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No feature of the application is considered critical unless it is expressly stated in the claims.
