Description

Technical Field

[0001] The utility model relates to the technical field of modular machines, in particular to a sewage discharge device for a modular machine. Background Art

[0002] During the long-term operation of the modular unit, water circulates continuously between the user side and the shell and tube heat exchanger, which can easily cause stains at the bottom of the shell and tube heat exchanger. If too much stain accumulates, it will affect the heat exchange effect of the shell and tube heat exchanger. At present, the modular unit discharges sewage directly to the outside of the unit through the bottom drain valve of the water-side heat exchanger (shell and tube, sleeve, high-efficiency tank).

[0003] The patent document with announcement number CN218524010U discloses a modular machine sewage discharge device, including a shell, a water side heat exchanger, a first ball valve, a second ball valve, a third ball valve, a fourth ball valve, a first three-way and a second three-way. One side of the bottom of the water side heat exchanger is connected with a water outlet pipe, one side of the water outlet pipe is connected to one side of the first ball valve, and the water outlet end of the first ball valve is connected with the first water pipe. When the unit is suddenly powered off or needs to be drained for maintenance, the utility model closes the third ball valve and opens the second ball valve and the fourth ball valve at the same time, so that the water inside the water side heat exchanger is discharged through the second water pipe, and the outside air enters the water side heat exchanger through the fourth ball valve, so as to avoid the pressure difference inside the water side heat exchanger when draining, ensure that the water inside the water side heat exchanger is drained cleanly, and at the same time make the drainage process of the modular machine simple and convenient to operate when draining sewage, reduce the customer's unwillingness to open the water side heat exchanger drain valve, and cause the loss of the water side heat exchanger to be frozen, but the prior art still has defects:

[0004] (1) The sewage discharge device of the prior art modular machine is not convenient for discharging impurities precipitated inside the water pipe, which makes it very inconvenient to clean the water pipe, resulting in poor water flow in the pipe. At the same time, the decomposition products of various microorganisms in the precipitated impurities easily cause pipe corrosion, shortening the service life of the pipe, thereby affecting the sewage discharge effect and thus affecting the use of the modular machine.

[0005] (2) When the modular sewage discharge device of the prior art is used under low ambient temperature, the sewage discharge pipe may freeze due to the low temperature of the discharged sewage. At the same time, multiple ball valves need to be operated during sewage discharge, which complicates the operation process and reduces the applicability of the device. Utility Model Content

[0030] The bottom of the water-side heat exchanger 2 is connected to a water outlet pipe 4, and the bottom of the water outlet pipe 4 is connected to an outlet pipe 5, which is inclined. A through hole 2 7 is opened at the bottom of one side of the shell 1, and the inner wall of the through hole 2 7 is inclined for use with the outlet pipe 5. One end of the outlet pipe 5 is inserted into the through hole 2 7, and the bottom of the end of the outlet pipe 5 extending out of the through hole 2 7 is connected to a drain pipe 9, and a ball valve 10 is provided on the drain pipe 9. When discharging sewage, it is only necessary to unscrew the ball valve 10 on the drain pipe 9 to discharge sewage, and the process is simpler.

[0031] An impurity removal structure 6 is provided at one end of the outlet pipe 5 close to the water outlet pipe 4. The impurity removal structure 6 includes an electric telescopic rod 61 fixedly mounted on one side of the inner wall of the shell 1. The electric telescopic rod 61 is arranged at the higher end of the outlet pipe 5. The output end of the electric telescopic rod 61 extends into the outlet pipe 5. The output end of the electric telescopic rod 61 is fixedly connected with a piston plate 62. The electric telescopic rod 61 is used to drive the piston plate 62 to reciprocate inside the inclined outlet pipe 5 to push impurities and sewage toward the lower side of the outlet pipe 5. The impurities and sewage will be discharged through the drain pipe 9 at the bottom, so that the sewage discharge is more thorough and the precipitated impurities are prevented from clogging the water pipe.
