DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
[0031] An embodiment of a defoamer of the present application, as shown in FIG. Figures 3 to 10 , comprises an upper defoaming net 300, a lower defoaming net 400 and a power piece 500.
[0032] The lower defoaming net 400 comprises a fixed cylinder 410 and a plurality of lower wire mesh discs 420. The fixed cylinder 410 is vertically and fixedly arranged, and the plurality of lower wire mesh discs 420 are circumferentially and uniformly distributed around the center cylinder 310 and sequentially connected, and are all fixed to the fixed cylinder 410. Each lower wire mesh disc 420 is arranged to be inclined relative to the vertical direction, and the inclination directions of adjacent two lower wire mesh discs 420 are opposite, so that the plurality of lower wire mesh discs 420 are in a wave shape in the circumferential direction of the fixed cylinder 410. The end of the plurality of lower wire mesh discs 420 connected with the fixed cylinder 410 is higher than the end away from the fixed cylinder 410.
[0033] The upper demisting screen 300 is located above the lower demisting screen 400, and includes a central cylinder 310 and a plurality of upper wire mesh discs 320. The central cylinder 310 is coaxial with the fixed cylinder 410 and can rotate about its own axis relative to the fixed cylinder 410. The plurality of upper wire mesh discs 320 are evenly distributed circumferentially around the central cylinder 310 and are sequentially connected and fixed to the central cylinder 310, and have the same shape as the plurality of lower wire mesh discs 420. That is, the plurality of upper wire mesh discs 320 are each arranged obliquely relative to the vertical direction, and the oblique directions of adjacent two upper wire mesh discs 320 are opposite, so that the plurality of upper wire mesh discs 320 are in a wave shape circumferentially around the central cylinder 310. One end of the plurality of upper wire mesh discs 320 connected to the central cylinder 310 is higher than the other end away from the central cylinder 310. The mesh of the upper wire mesh disc 320 is smaller than the mesh of the lower wire mesh disc 420.
[0034] The power member 500 is used to push the central cylinder 310 to rotate in the positive direction and allow the central cylinder 310 to rotate in the positive direction relative to the power member 500. An elastic member 510 is arranged between the power member 500 and the upper demisting screen 300, and the elastic member 510 promotes the abutment of the upper wire mesh disc 320 and the lower wire mesh disc 420.
[0035] In use, the steam carrying the mist passes through the lower demisting screen 400 and the upper demisting screen 300 in turn from bottom to top. The mist collides with the wire mesh of the lower wire mesh disc 420 or the upper wire mesh disc 320 and adheres to the surface of the wire. With the diffusion and gravity settlement of the mist on the surface of the wire, the mist gradually gathers into larger droplets and then falls. Because one end of the plurality of upper wire mesh discs 320 connected to the central cylinder 310 is higher than the other end away from the central cylinder 310, and one end of the plurality of lower wire mesh discs 420 connected to the fixed cylinder 410 is higher than the other end away from the fixed cylinder 410, compared with the horizontally arranged demisting screen, not only the contact area with the steam can be increased, but also the droplets on the upper wire mesh disc 320 and the lower wire mesh disc 420 can be made to fall from the edges of the upper demisting screen 300 and the lower demisting screen 400, reducing the influence of the droplets on the rising steam.
[0036] Since the plurality of upper wire mesh discs 320 are connected in sequence and in a wave shape around the central cylinder 310, the plurality of upper wire mesh discs 320 form alternating upward protrusions and downward protrusions, and the plurality of lower wire mesh discs 420 form alternating upward protrusions and downward protrusions around the fixed cylinder 410; the power member 500 pushes the central cylinder 310 to rotate forward, thereby driving the upper wire mesh disc 320 to rotate forward, so that the downward protrusions of the upper wire mesh disc 320 move from the downward protrusions of the lower wire mesh disc 420 to the upward protrusions of the lower wire mesh disc 420, and in this process, the elastic member 510 is compressed; when the downward protrusions of the upper wire mesh disc 320 abut against the upward protrusions of the lower wire mesh disc 420, the elastic member 510 drives the upper wire mesh disc 320 to move downward, so that the downward protrusions of the upper wire mesh disc 320 quickly move downward along the inclined surface of the lower wire mesh disc 420 to the downward protrusions of the lower wire mesh disc 420, and at the same time, the upper wire mesh disc 320 rotates forward relative to the power member 500, and then the upper wire mesh disc 320 continues to rotate forward under the pushing of the power member 500. Wherein, the forward rotation is to illustrate the rotating direction of the power member 500 and the rotating direction of the upper wire mesh disc 320 relative to the power member 500, and does not specify a certain direction. Through the cooperation of the power member 500 and the elastic member 510, the upper wire mesh disc 320 slowly rotates and moves upward under the pushing of the power member 500, and quickly rotates and moves downward under the driving of the elastic member 510, so that the upper mist removal net 300 and the lower mist removal net 400 are intermittently impacted, the mist on the upper wire mesh disc 320 and the lower wire mesh disc 420 is accelerated to converge and drop, and the influence of the steam passing through caused by the mist adhering to the upper wire mesh disc 320 is avoided.

The upper end of the central cylinder 310 is blocked and the lower end is open and blocked by a flexible film cloth 311, and the middle part of the flexible film cloth 311 is connected with the fixed cylinder 410; specifically, a connecting seat 411 is arranged in the fixed cylinder 410, and the connecting seat 411 is connected with the middle part of the flexible film cloth 311 through a connecting rod 412. When the central cylinder 310 moves up and down relative to the fixed cylinder 410, the pressure in the central cylinder 310 is changed through the flexible film cloth 311. During the process that the upper defoaming net 300 rotates and the downward protrusions of the upper wire mesh discs 320 move from the downward protrusions of the lower wire mesh discs 420 to the upward protrusions of the lower wire mesh discs 420, the central cylinder 310 moves upward relative to the fixed cylinder 410, the middle part of the flexible film cloth 311 relaxes downward relative to the central cylinder 310, the suction pipe 330 is suctioned, and the holes on the upper side of the suction pipe 330 suction the liquid droplets gathered at the connected position on the lower side of the upper wire mesh disc 320. During the process that the elastic member 510 pushes the downward protrusions of the upper wire mesh discs 320 to quickly rotate along the inclined surface of the lower wire mesh discs 420 to the downward protrusions of the lower wire mesh discs 420, the central cylinder 310 moves downward relative to the fixed cylinder 410, the middle part of the flexible film cloth 311 moves upward relative to the central cylinder 310, and the gas in the central cylinder 310 and the suction pipe 330 is extruded, so that the liquid or gas in the suction pipe 330 is sprayed from the holes on the lower side of the suction pipe 330, and the lower wire mesh discs 420 are backflushed to make the liquid droplets on the lower wire mesh discs 420 gather and drop. The flexible film cloth 311 is arranged, the suction pipe 330 communicates with the inside of the central cylinder 310, the suction pipe 330 alternately performs suction and spraying by using the up-and-down movement of the central cylinder 310 when the upper defoaming net 300 rotates, liquid droplets on the upper wire mesh discs 320 can be recovered, the lower wire mesh discs 420 can be backflushed and the liquid droplets on the lower wire mesh discs 420 can be made to drop, the upper defoaming net 300 and the lower defoaming net 400 can be cleaned, and the influence of the liquid droplets on the surface of the upper defoaming net 300 and the lower defoaming net 400 on the steam passing through can be further reduced.

Wherein, the center cylinder 310 can be limited in the inner wall of the fixed cylinder 410 to avoid shaking during the up and down movement.

[0040] In the embodiment, the inclination degree of the center and the edge of the wave-shaped structure surrounded by the plurality of upper wire mesh discs 320 is consistent with the inclination degree of the center and the edge of the wave-shaped structure surrounded by the plurality of lower wire mesh discs 420, so that when the spray suction pipe 330 moves to the position above the connection position between the lower sides of two adjacent lower wire mesh discs 420, the wave-shaped structure surrounded by the plurality of upper wire mesh discs 320 is parallel to the wave-shaped structure surrounded by the plurality of lower wire mesh discs 420, and the upper defoaming net 300 rotates relative to the lower defoaming net 400 by abutting against the lower wire mesh disc 420 through the spray suction pipe 330.
