DETAILED DESCRIPTION
[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0020] Please refer to Figs. 1-2 In the embodiments of the present application, the discharge device capable of realizing liquid level control comprises a liquid storage assembly 1 composed of a liquid storage tank 101, a liquid inlet 102, a flange top cover 103, a water inlet connecting pipe 104, a mounting port 106 and a liquid outlet 107. The liquid inlet 102 is integrally formed on the top of the liquid storage tank 101. The flange top cover 103 is fixedly installed on the upper surface of the liquid inlet 102. The water inlet connecting pipe 104 and the mounting port 106 are both fixedly installed on the top of the flange top cover 103 and are in communication with the inner cavity of the liquid storage tank 101. The liquid outlet 107 is fixedly installed on the bottom of one end of the liquid storage tank 101 and is in communication with the inner cavity of the liquid storage tank 101.
[0021] The top of the mounting port 106 is provided with a liquid level meter 2. The probe rod of the liquid level meter 2 extends to the bottom of the inner cavity of the liquid storage tank 101. The liquid level meter 2 is used for monitoring the liquid level in the liquid storage tank 101.
[0022] One end of the liquid outlet 107 is provided with a water pump 3. The input end of the water pump 3 is connected in communication with the liquid outlet 107. The output end of the water pump 3 is connected with a conveying pipe 5 through a hand-operated stop valve 4. The water pump 3 is used for conveying the wastewater in the liquid storage tank 101 to a wastewater treatment area through the channel composed of the liquid outlet 107, the hand-operated stop valve 4 and the conveying pipe 5.
[0023] A backflow assembly 6 is further arranged between the conveying pipe 5 and the liquid storage tank 101. The backflow assembly 6 is used for realizing the backflow of the residual wastewater in the conveying pipe 5 to the inside of the liquid storage tank 101 when the water pump 3 stops running.
[0024] The backflow assembly 6 comprises an L-shaped backflow pipe 601, an electromagnetic valve 602 and a second backflow pipe 603.
[0025] The top of the flange top cover 103 is further fixedly provided with a backflow port 105 in communication with the inner cavity of the liquid storage tank 101. One end of the L-shaped backflow pipe 601 is connected in communication with the backflow port 105. The other end of the L-shaped backflow pipe 601 is connected with the conveying pipe 5 through the electromagnetic valve 602.
[0026] The second backflow pipe 603 is fixedly installed between the bottom of the L-shaped backflow pipe 601 and the top of the liquid storage tank 101 and is in communication with the inner cavity of the liquid storage tank 101 and the inner cavity of the L-shaped backflow pipe 601.
[0027] When the water pump 3 stops running, the electromagnetic valve 602 starts to open to make the wastewater inside the conveying pipe 5 backflow to the inside of the liquid storage tank 101 through the channel composed of the electromagnetic valve 602, the L-shaped backflow pipe 601 and the second backflow pipe 603;
[0028] The liquid level meter 2, the water pump 3 and the electromagnetic valve 602 are electrically connected with the external controller through cables.
[0029] In the embodiment, it is to be noted that the liquid inlet 102 is communicated with the laboratory wastewater pipeline, and the conveying pipe 5 is communicated with the collection pool in the wastewater treatment area, and the working principle is as follows:
[0030] The laboratory wastewater is conveyed to the liquid storage tank 101 for temporary storage and collection, and in this process, the liquid level meter 2 monitors the water level inside the liquid storage tank 101, and when the monitored water level reaches the set maximum water level, the external controller starts the water pump 3, and the water pump 3 runs to convey the wastewater inside the liquid storage tank 101 to the wastewater treatment area through the channel composed of the liquid outlet 107, the manual stop valve 4 and the conveying pipe 5 (it is to be noted that the manual stop valve 4 is in an open state);
[0031] With the continuous conveying of the wastewater, the water level inside the liquid storage tank 101 decreases, and when the monitored water level reaches the set minimum water level, the water pump 3 stops running, and then the above operation is repeated, so that the automatic conveying management of the laboratory wastewater can be realized;
[0032] When the water pump 3 stops running, there will be residual wastewater inside the conveying pipe 5, and in the cold weather in winter, the residual wastewater inside the conveying pipe 5 will freeze, which not only affects the conveying of the wastewater, but also causes damage to the conveying pipe 5 in severe cases. However, the backflow assembly 6 can avoid this situation, and the working principle is as follows:
[0033] When the water pump 3 runs, the electromagnetic valve 602 is in a closed state, which can avoid the backflow of the wastewater. When the water pump 3 stops running, the electromagnetic valve 602 is opened synchronously, and at this time the wastewater inside the conveying pipe 5 will quickly backflow to the inside of the liquid storage tank 101 through the L-shaped backflow pipe 601 and the second backflow pipe 602 (it is to be noted that the structures of the L-shaped backflow pipe 601 and the second backflow pipe 602 are arranged to increase the backflow speed of the wastewater), so as to avoid the residual wastewater inside the conveying pipe 5, thereby avoiding the damage of the conveying pipe 5 caused by the freezing of the residual wastewater. It is to be noted that the connection part between the conveying pipe 5 and the electromagnetic valve 602 is upwardly distributed, and the part of the conveying pipe 5 horizontally conveying is arranged in the air through the bridge arrangement, so that the backflow of the wastewater can be realized through the self-weight of the wastewater;
[0034] It is to be further noted that in the case of non-cold weather, the electromagnetic valve 602 can be set to be in a closed state all the time, and at this time the wastewater does not need to backflow.
[0035] Please refer to Figs. 1-2 The outer side of the delivery pipe 5, the L-shaped return pipe 601, the electromagnetic valve 602 and the second return pipe 603 are all covered with a heat preservation layer.
[0036] In this embodiment, the delivery pipe 5 and the return assembly 6 are protected by the heat preservation layer, so that the device can normally operate in cold weather.
[0037] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
