DETAILED DESCRIPTION

[0027] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] As Figure 1 shown, a heat pump system with a separator includes a separation cylinder 1, an inlet pipe 2, an exhaust pipe 3 and a drain pipe 15, and the separator further includes:

[0029] Baffle plates 8, a plurality of baffle plates 8 are installed in the separation cylinder 1, one end of the baffle plate 8 is elastically connected to the inner wall of the separation cylinder 1, so that the baffle plate 8 always has a tendency to rotate upward, the plurality of baffle plates 8 are staggered at the head and tail, and are all inclined from the movable end to the end, and a plurality of baffle plates 8 form a plurality of curved steam flow channels;

[0030] Water collecting net plate 9, the bottom of the baffle plate 8 is provided with a water collecting net plate 9 except the lowermost baffle plate 8, the water collecting net plate 9 is slidingly installed at the bottom of the baffle plate 8, and the top of the water collecting net plate 9 is in a rotating state, and the water collecting net plate 9 is close to the end of the baffle plate 8;

[0031] Driving mechanism, a driving mechanism is installed in the inner wall of the separation cylinder 1 and the gas inlet pipe 2, and drives the baffle plate 8 to rotate downward.

[0032] In one case of the embodiment, the elastic rotating part of the baffle plate 8 can be provided with a torsional spring.

[0033] In actual application, the wet steam generated by the wastewater enters the separation cylinder 1 through the gas inlet pipe 2, and the wet steam passes through the plurality of curved steam flow channels, increasing the path of steam flow. When the wet steam encounters the baffle plate 8, because the water droplets have a large mass and inertia, they will move along the surface of the baffle plate 8 and eventually be intercepted, while the steam can bypass the baffle plate 8 and continue to flow. The wet steam is also intercepted by the plurality of water collecting net plates 9 in the path when passing through the steam flow channel, thereby intercepting the water in the wet steam. In this way, the wet steam is separated into steam and water by the baffle plate 8 and the water collecting net plate 9, improving the separation efficiency.

[0034] When the baffle plate 8 and the water collecting net plate 9 intercept the water, the driving mechanism makes the plurality of baffle plates 8 rotate downward alternately and intermittently, and cooperates with the elastic rotation of the baffle plate 8, so that the baffle plate 8 rotates upward after rotating downward, thereby causing the baffle plate 8 to shake in this process, and further causing the water intercepted on the baffle plate 8 and the water collecting net plate 9 to fall down and flow along the plurality of baffle plates 8, and finally be discharged from the drain pipe 15. In this way, water can be effectively prevented from adhering to the surface of the baffle plate 8 and the water collecting net plate 9, thereby preventing the dry steam from encountering water again to become wet steam, so that the steam discharged from the exhaust pipe 3 remains dry, avoiding reducing the heat conduction performance and heat exchange efficiency of the steam.

[0035] Further, the driving mechanism comprises:

[0036] Impeller 4, an impeller 4 is rotatably installed in the gas inlet pipe 2, and the impeller 4 is coaxial with the gas inlet pipe 2;

[0037] The rotating rod one 6 and the rotating rod two 12 are respectively rotatably installed in the inner walls of the two sides of the separation cylinder 1, the rotating rod one 6 is in transmission connection with the output shaft of the impeller 4 through the transmission member one 5, the rotating rod one 6 is in transmission connection with the rotating rod two 12 through the transmission member four 14, and the transmission member four 14 is installed in the inner wall of the top of the inner cavity of the separation cylinder 1;

[0038] The cam 11 is rotatably installed in the inner walls of the two sides of the inner cavity of the separation cylinder 1, the rotating bottom end of the cam 11 abuts against the top of the end of the baffle plate 8, the cam 11 close to the rotating rod one 6 is in transmission connection with the rotating rod one 6 through the transmission member two 7, and the cam 11 close to the rotating rod two 12 is in transmission connection with the rotating rod two 12 through the transmission member three 13.

[0039] The protruding part of the cam 11 connected with the rotating rod one 6 faces the opposite direction of the protruding part of the cam 11 connected with the rotating rod two 12, so that the plurality of baffle plates 8 on the left and right sides are alternately downwardly rotated.

[0040] In one case of the embodiment, the transmission member one 5, the transmission member two 7 and the transmission member three 13 can all be two bevel gears in mesh with each other, or can be other components capable of transmission; the transmission member four 14 can be a belt pulley and a belt, or can be other components capable of transmission.

[0041] In actual application of the embodiment, the wet steam enters into the separation cylinder 1 through the air inlet pipe 2, the power of the wet steam flow makes the impeller 4 rotate, the impeller 4 makes the rotating rod one 6 rotate through the transmission member one 5, the rotating rod one 6 makes the rotating rod two 12 rotate through the transmission member four 14, the rotating rod one 6 makes the plurality of cams 11 connected therewith rotate through the transmission member two 7, and the rotating rod two 12 makes the plurality of cams 11 connected therewith rotate through the transmission member three 13, so that the protruding part of the cam 11 extrudes the baffle plate 8, and the baffle plate 8 is downwardly rotated, thereby making the water attached to the baffle plate 8 and the water collecting net plate 9 fall down;

[0042] The plurality of cams 11 on the left and right sides make the plurality of baffle plates 8 on the left and right sides alternately downwardly rotate, so that the water on all the baffle plates 8 does not fall down and splash everywhere when all the baffle plates 8 are downwardly rotated and swing, the contact between the water and the dry steam is avoided, the separation efficiency of the wet steam is improved, the steam discharged from the air outlet pipe 3 is kept in a dry state, and the heat conduction performance and the heat exchange efficiency of the steam are avoided from being reduced.

[0043] Further, a plurality of elastic columns 10 are arranged between the front and rear inner walls of the inner cavity of the separation cylinder 1, and the elastic columns 10 are located below the baffle plate 8.
