Abstract

The invention relates to a sewage collecting and discharging device comprising a collecting pit connected with a sewage inlet pipe; the collecting pit is connected with a valve chamber; a sewage discharge pipe is inserted in the collecting pit; a discharge valve is arranged on the sewage discharge pipe, and is connected with a control box which controls the discharge valve to be opened and closed; the control box is connected with a liquid level switch in the collecting pit; and the sewage discharge pipe is connected with a vacuum system. One end of the device is connected with the sanitary ware of a building, and the other end thereof is connected with a vacuum pipeline and a vacuum pump station; and the device can be used in the regions without gravity water discharge pipelines or being difficult to lay gravity pipelines, and solves discharge and transmission of life sewage. The vacuum water discharge system by utilizing the device has the obvious characteristics of relatively smaller pipeline specification, flexible construction, lower construction cost non-leakage seal and the like.

[0017] A sewage collection and discharge device, comprising a collection pit 6 connected with a sewage inlet pipe 11, the collection pit 6 is connected with a valve chamber 2, a sewage discharge pipe 9 is inserted in the collection pit 6, and a discharge valve 3 is arranged on the sewage discharge pipe 9 to discharge The valve 3 is connected with the control box 10 which controls its opening and closing, the control box 10 is connected with the liquid level switch 7 in the collection pit 6, and the sewage pipe 9 is connected with the vacuum system 28.

[0018] The discharge valve 3 is a vacuum angle seat valve, comprising a piston cylinder 27, the piston cylinder 27 is provided with a piston 15, the piston 15 is connected with a valve core 20 through a pull rod, and the valve core 20 is sealed with the valve seat 18 of the valve body, The rubber diaphragm 16 divides the piston cylinder 27 into a control chamber 24 above the piston and a free chamber 22 below. The upper end of the control chamber 24 is provided with a control chamber interface 13 connected to the control box 10, and the control chamber interface 13 is connected to the piston 15. A spring 14 is arranged between them, and a vent hole 21 is arranged on the free cavity 22 .

[0019] The sewage collection and discharge device of the present invention is buried underground when in use, the collection pit 6 is connected to the blowdown pipe of the building, the blowdown pipe 9 of the device is connected to the vacuum system 28, the valve chamber 2 and the collection pit 6 are sealed with a partition 5, and the valve chamber 2 Install the discharge valve 3 and the control box 10 in the middle.

[0020] When the sewage in the collection pit 6 reaches a certain level and needs to be discharged, the liquid level switch 7 installed in the collection pit 6 transmits the liquid level signal to the control box 10, and the control device is connected to the vacuum and the discharge valve 3, and the discharge valve 3 is in the vacuum Open under action, when the sewage is sucked clean, the control device cuts off the communication between the vacuum and the discharge valve 3, and the discharge valve 3 is closed.

[0021] The closed state of the discharge valve 3 is that the control chamber 25 and the free chamber 23 are open to the atmosphere, and the valve core 20 is sealed and combined with the valve seat 18 under the action of the spring 14. When the valve needs to be opened for sewage discharge, the vacuum communicates with the control chamber 25, and the free chamber 23 and The pressure difference of the control chamber 25 overcomes the effect of the spring and moves up to open the valve, the sewage is sucked away by the vacuum, and after the suction is completed, the connection between the vacuum and the control chamber 25 is cut off, the control chamber 25 is ventilated to the atmosphere, and the valve is closed.

[0022] The opening and closing of the discharge valve 3 is realized by the control box 10 in the valve chamber 2. There is an electronically controlled three-way valve in the control box 10. The three connections of the three-way valve are respectively the vacuum port 19, the control chamber 25 and the atmosphere, liquid The signal of position switch 7 is transmitted to the control panel, and the control panel is responsible for connecting and cutting off the three-way valve according to the set time, so as to realize the opening and closing of the valve. The control box is powered by dry batteries or lithium batteries.

[0023] The valve chamber and the collection pit are separated and sealed with a partition, which can prevent the sewage odor from overflowing, and can also prevent extra flow such as outdoor rainwater from entering the system and affecting the normal operation of the vacuum system.

[0024] A vent needs to be set on the sewage inlet pipe connected to the building and the device of the present invention, so as to ensure that the sewage can smoothly flow into the collection pit and communicate with the atmosphere all the time.

[0025] The control chamber and free chamber of the vacuum angle seat valve are connected to the collection pit through a ventilator, which has a float check valve to ensure the safety of the ventilator.
