[0023] The embodiment of the present application provides a peak condenser for reducing the back pressure of the unit during high back pressure operation, which effectively solves the problem that in actual use, the water in the condenser will contain dissolved gas and solid impurities, which will cause blockage of the drain port and increase the back pressure after long-term operation. The peak condenser for reducing the back pressure of the unit during high back pressure operation, the condensate generated during the operation of the peak condenser body is discharged into the connecting head, from the connecting head to the receiving groove, and then from the through hole to the drain pipe, and is discharged from the drain pipe. The motor is started to rotate the cam. When the raised portion of the cam contacts the surface of the connecting piece, the cam applies a force to the connecting piece to cause the connecting piece to move, and the movement of the connecting piece will act on the spring. The force causes the spring to be compressed. When the raised part of the cam does not contact the surface of the connecting piece, the elastic restoring effect of the spring is used to reset the connecting piece and the drain pipe. As the cam continues to rotate, it will drive the connecting piece and the drain pipe to move back and forth and vibrate, avoiding the blockage of the drain pipe due to impurities carried in the condensate, thereby ensuring the smooth discharge of the condensate, preventing the condensate from flowing back, reducing the back pressure, and supporting and limiting the connecting piece through the limit rod that movably penetrates the connecting plate, making the movement of the connecting piece and the drain pipe more stable and ensuring stable use. The bottom surface of the inner wall of the receiving groove is inclined, so that the condensate will not be blocked in the receiving groove. The connecting plate is slidably installed on the upper end of the connecting piece to prevent the condensate from leaking out of the connecting piece.

The condensate generated during the operation of the peak condenser body 1 is discharged into the connector 41, and then discharged from the connector 41 to the receiving groove 31, and then discharged from the through hole 32 to the drain pipe 2, and discharged from the drain pipe 2. The motor 61 is started to rotate the cam 62. When the raised portion of the cam 62 contacts the surface of the connecting member 3, the cam 62 applies a force to the connecting member 3, so that the connecting member 3 moves. The movement of the connecting member 3 applies a force to the spring 51, so that the spring 51 is compressed. When the raised portion of the cam 62 does not contact the surface of the connecting member 3, the elastic reset effect of the spring 51 is used to reset the connecting member 3 and the drain pipe 2. With the continuous rotation of the cam 62, the connecting member 3 and the drain pipe 2 are driven to reciprocate and vibrate, so as to avoid the blockage of the drain pipe 2 due to impurities carried by the condensate, thereby ensuring the smooth discharge of the condensate, preventing the condensate from flowing back, and reducing the back pressure.

[0026] A limiting rod 5 is fixedly installed on the connecting member 3, wherein the limiting rod 5 movably passes through the connecting plate 4, and a spring 51 is movably sleeved on the limiting rod 5, wherein the connecting member 3 is fixedly connected to the connecting plate 4 through the spring 51, and a limiting block 52 is fixedly installed on the end of the limiting rod 5, and the limiting block 52 is located on the outer side of the connecting plate 4.

[0027] Working principle:

[0028] In the first step, the condensate generated during the operation of the peak condenser body 1 is discharged into the connecting head 41, and then discharged from the connecting head 41 to the receiving groove 31, and then discharged from the through hole 32 to the drain pipe 2, and discharged from the drain pipe 2. The motor 61 is started to rotate the cam 62. When the raised portion of the cam 62 contacts the surface of the connecting member 3, the cam 62 applies a force to the connecting member 3, so that the connecting member 3 moves. The movement of the connecting member 3 applies a force to the spring 51, so that the spring 51 is compressed. When the raised portion of the cam 62 does not contact the surface of the connecting member 3, the elastic reset effect of the spring 51 is utilized to reset the connecting member 3 and the drain pipe 2. As the cam 62 continues to rotate, it drives the connecting member 3 and the drain pipe 2 to reciprocate and vibrate, avoiding the blockage of the drain pipe 2 due to impurities carried in the condensate, thereby ensuring the smooth discharge of the condensate, preventing the condensate from flowing back, and reducing the back pressure.
