[0030] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.
[0031] Figure 1 It is a schematic diagram of the layout of the hydrolyzer sewage treatment device. Figure 1 As shown, the utility model provides a hydrolyzer sewage discharge device, and the hydrolyzer sewage discharge device comprises:
[0032] A first sewage pipe 1, one end of which is connected to the first sewage outlet of the hydrolyzer 3, and the other end of which is connected to the water inlet of the sewage tank 5 of the chemical water treatment workshop, and the sewage at the bottom of the hydrolyzer 3 is discharged into the sewage tank 5 of the chemical water treatment workshop through the first sewage pipe 1;
[0033] A second sewage pipe 2, one end of which is connected to the second sewage outlet of the hydrolyzer 3, and the other end of which is connected to the water inlet of the sewage tank 5 of the chemical water treatment workshop, and the sewage at the top of the hydrolyzer 3 is discharged into the sewage tank 5 of the chemical water treatment workshop through the second sewage pipe 2;
[0034] The water pump 4 is connected to the first sewage pipe 1 and the second sewage pipe 2 , and is used for pumping clean water into the first sewage pipe 1 and the second sewage pipe 2 to dilute the sewage entering the sewage tank 5 .
[0035] The sewage discharge device of the hydrolyzer provided by the utility model is provided with a first sewage discharge pipe 1 and a second sewage discharge pipe 2. One end of the first sewage discharge pipe 1 is connected to the first sewage discharge port of the hydrolyzer 3 located at the bottom, and the other end is connected to the water inlet of the sewage tank 5 of the chemical water treatment workshop. The sewage at the bottom of the hydrolyzer 3 is discharged into the sewage tank 5 through the first sewage discharge pipe 1. One end of the second sewage discharge pipe 2 is connected to the second sewage discharge port of the hydrolyzer 3, and the other end is connected to the water inlet of the sewage tank 5 of the chemical water treatment workshop. The sewage at the top of the hydrolyzer 3 is discharged into the sewage tank 5 through the second sewage discharge pipe 2. The entire sewage discharge process is completed through a closed pipeline, so that the ammonia in the sewage cannot be emitted into the air, and clean water is directly pumped into the first sewage discharge pipe 1 and the second sewage discharge pipe 2 by a water pump 4 to dilute the sewage discharged into the sewage tank 5. The sewage dilution is also carried out in the closed pipeline, which prevents the ammonia generated in the sewage dilution process in the wastewater pit from being emitted into the air.
[0036] The occurrence of the urea solution in the wastewater pit and the crystals precipitated from the urea solution adhering to the impeller of the wastewater pump solves the problems in the prior art of environmental pollution caused by the ammonia gas emitted after the sewage is discharged into the wastewater pit and the damage to the wastewater pump caused by the crystals precipitated from the urea solution.
[0037] In order to better dilute the sewage, such as Figure 1 As shown, the hydrolyzer sewage discharge device further includes: a mixing pipe 6;
[0038] The first sewage pipe 1 and the second sewage pipe 2 are both connected to the water inlet of the sewage tank 5 of the chemical water treatment workshop through the mixing pipe 6;
[0039] The water pump 4 is connected to the first sewage pipe 1 and the second sewage pipe 2 through the mixing pipe 6 .
[0040] One end of the mixing tube 6 is connected to the water inlet of the sewage tank 5, and the other end is connected to the first sewage pipe 1 and the second sewage pipe 2. The sewage discharged from the first sewage pipe 1 and the sewage discharged from the second sewage pipe 2 are mixed in the mixing tube 6, and the water outlet of the water pump 4 is connected to the mixing tube 6. In this way, the sewage entering the mixing tube 6 and the clean water pumped into the mixing tube 6 by the water pump 4 are mixed in the mixing tube 6, thereby completing the dilution of the sewage.
[0041] In order to prevent particulate impurities in the sewage from entering the sewage tank 5, the hydrolyzer sewage discharge device also includes: a filter basket 7, which is detachably arranged in the sewage tank 5, located at the water inlet of the sewage tank 5, and is used to filter out particulate impurities in the sewage entering the sewage tank 5.
[0042] The filter basket 7 is detachably arranged in the sewage tank 5 via a hook.
[0043] The sewage entering the sewage tank 5 is preliminarily filtered by a filter basket 7 detachably arranged in the sewage tank 5, and the water-insoluble particulate impurities in the sewage are filtered out to prevent the particulate impurities from being deposited in the sewage tank 5. A hook is arranged on the wall of the sewage tank 5, and a hanging groove that fits with the hook is arranged on the filter basket 7. The filter basket 7 is hung below the water inlet in the sewage tank 5 through the cooperation of the hanging groove and the hook.
[0044] In order to facilitate the control of the flow of sewage, the hydrolyzer sewage discharge device also includes: a plurality of first control valves 8, at least one first control valve 8 is provided at the port where the first sewage pipe 1 is connected to the first sewage outlet, at the port where the second sewage pipe 2 is connected to the second sewage outlet, and at the outlet of the water pump 4, the flow of sewage in the first sewage pipe 1 and the second sewage pipe 2 is controlled.
[0045] The flow of clean water at the outlet of the water pump 4 is controlled by the first control valve 8. When discharging sewage, the first control valve 8 is opened, and the sewage discharged from the first sewage outlet and the second sewage outlet enters the corresponding first sewage pipe 1 and the second sewage pipe 2 and then flows into the mixing pipe 6. At the same time, the water pump 4 also pumps clean water into the mixing pipe 6, so that the sewage enters the mixing pipe 6 through the first sewage pipe 1 and the second sewage pipe 2 and mixes with the clean water entering the mixing pipe 6, thereby diluting the sewage; when there is no need to discharge sewage, the first control valve 8 is closed, the sewage in the hydrolyzer 3 cannot flow into the first sewage pipe 1 and the second sewage pipe 2, and the clean water pumped by the water pump 4 cannot enter the mixing pipe 6. Usually, when the first control valve 8 at the outlet of the water pump 4 is closed, the water pump 4 also stops working.
[0046] In one embodiment, Figure 1 As shown, in order to avoid blockage of the first sewage pipe 1 and the second sewage pipe 2, the hydrolyzer sewage discharge device also includes: a cleaning component 9, which is selectively connected to the first sewage pipe 1 and the second sewage pipe 2, and is used for cleaning the first sewage pipe 1 and the second sewage pipe 2.

[0049] The cleaning pump 91 is arranged in the cleaning box 92, and a cleaning pipe 93 is respectively arranged between the water outlet of the cleaning pump 91 and the first sewage pipe 1 and the second sewage pipe 2.

[0052] The cleaning assembly 9 further includes: two second control valves 95 . One end of the cleaning pipe 93 connected to the cleaning pump 91 is provided with a corresponding second control valve 95 . The flow of the cleaning liquid in the cleaning pipe 93 is controlled by the corresponding second control valve 95 .
[0053] The cleaning liquid is stored in the cleaning tank 92. In order to improve the cleaning effect of the first sewage pipe 1 and the second sewage pipe 2, a heating control device 94 is arranged in the cleaning tank 92. The heating control device 94 includes an electric heating rod and a heating controller. The electric heating rod is arranged in the cleaning tank 92. The cleaning liquid is heated by the electric heating rod to improve the cleaning efficiency. In order to prevent the cleaning liquid temperature from being too high or too low to affect the cleaning effect, a temperature sensor is arranged in the cleaning tank 92 to detect the temperature of the cleaning liquid in real time. The heating controller is connected to the temperature sensor signal. The heating controller turns on or off the electric heating rod according to the temperature value of the cleaning liquid. In order to flexibly clean the first sewage pipe 1 and the second sewage pipe 2, such as Figure 1 As shown, a second control valve 95 is provided at one end of the first sewage pipe 1 connected to the cleaning pump 91 and at one end of the second sewage pipe 2 connected to the cleaning pump 91. The second control valve 95 controls whether the cleaning liquid can flow in the first sewage pipe 1 and the second sewage pipe 2 to perform cleaning operations.
