In the present invention, the steam passing through the first rectangular groove A can hit the condensation baffle B, and the steam passing through the rectangular groove B can hit the second condensation baffle A, so that the steam can automatically change the moving direction in the condensation shell, thereby increasing the contact area with the condensation shell, the two condensation baffles A and the condensation baffle B, and improving the condensation efficiency; the arrangement of two rows of heat dissipation fins facilitates the heat dissipation in the condensation shell;

[0021] In addition, the steam can pass through eight condensation shells in sequence to ensure the condensation effect, and the condensed liquid in the remaining seven condensation shells can enter the condensation shell on the right through seven sets of connecting hoses A, which is convenient for the discharge of the condensed liquid.

[0022] 2. When steam is generated in the heating tank of the present invention, the octagonal tube can automatically move upward under the action of steam pressure, so that the eight circular through holes B are concentric with the eight circular through holes A; the steam in the heating tank can enter the condensation shell on the right rear side through the eight circular through holes A, the eight circular through holes B, the hollow gas collecting hood and the two connecting hoses B;

[0023] In addition, when the octagonal tube moves upward under the action of steam pressure, the eight driving brackets can push the eight groups of circular movable rods to move outward at the same time, so that the spacing between the eight condensation shells becomes larger, which is beneficial to improve the heat dissipation effect of the eight condensation shells; at the same time, after the eight groups of circular movable rods move outward, the seven groups of connecting hoses A are all in a straightened state, which is convenient for the complete discharge of the condensed liquid;

[0026] In addition, when there is a steam leak in the device, part of the steam will be discharged through the leaking position under the sealing block of the L-shaped multi-function plate, shortening the moving distance of the movable discharge pipe; at this time, when the micro-electric cylinder drives the L-shaped multi-function plate to move downward, the L-shaped multi-function plate will press the switch, causing the alarm to sound, so that the staff can know that there is a steam leak in the device and repair the leaking position in time;

[0027] In addition, when there is no steam leakage in the device, the movable discharge pipe can move to a pre-set position under the sealing block of the L-shaped multi-function plate; at this time, when the micro-electric cylinder drives the L-shaped multi-function plate to move downward, the L-shaped multi-function plate will not press the switch; when the micro-electric cylinder drives the L-shaped multi-function plate to reset upward, the movable discharge pipe automatically resets under the elastic force of six coil springs B; wherein, the micro-electric cylinder is controlled to work intermittently through an external controller to realize intermittent detection of steam leakage.

When steam is generated in the heating tank 100, under the action of the steam pressure, the octagonal tube 201 can automatically move upward to make the eight circular through holes B4011 concentric with the eight circular through holes A2011; the steam in the heating tank 100 can enter the condensation shell 3031 on the right rear side through the eight circular through holes A2011, the eight circular through holes B4011, the hollow gas collecting hood 401 and the two connecting hoses B402; when the octagonal tube 201 is in the steam When moving upward under the action of pressure, the eight driving brackets 203 can push the eight groups of circular movable rods 302 to move outward at the same time, so that the spacing between the eight condensation shells 3031 becomes larger, which is beneficial to improve the heat dissipation effect of the eight condensation shells 3031; at the same time, after the eight groups of circular movable rods 302 move outward, the seven groups of connecting hoses A304 are all in a straightened state, which is convenient for the complete discharge of the condensed liquid; the steam passing through the first rectangular groove A30321 can hit the condensation baffle B3033, and the steam passing through the rectangular groove B30331 can hit the second condensation baffle A3032, so that the steam can automatically change the moving direction in the condensation shell 3031, thereby improving the connection with the condensation shell 3031 and the two condensation baffles A303 2 and the contact area of ​​the condensation baffle B3033, thereby improving the condensation efficiency. The arrangement of two rows of heat dissipation fins 30311 facilitates the heat dissipation in the condensation shell 3031; the steam can pass through eight condensation shells 3031 in sequence, thereby ensuring the condensation effect; the condensed liquid in the other seven condensation shells 3031 can enter the condensation shell 3031 on the right through seven sets of connecting hoses A304, thereby facilitating the discharge of the condensed liquid; when the output shaft of the micro-electric cylinder 603 is extended, the L-shaped multifunctional plate 602 can seal the movable discharge pipe 502; when there is a steam leak in the device, a part of the steam will be discharged through the leakage position under the sealing blockage of the L-shaped multifunctional plate 602, thereby changing the moving distance of the movable discharge pipe 502. short; at this time, when the micro-electric cylinder 603 drives the L-shaped multi-function board 602 to move downward, the L-shaped multi-function board 602 will press the switch 607, so that the alarm 605 will sound an alarm, so that the staff can know that there is a steam leak in the device and repair the leak in time; when there is no steam leak in the device, under the sealing block of the L-shaped multi-function board 602, the movable discharge pipe 502 can move to a preset position; at this time, when the micro-electric cylinder 603 drives the L-shaped multi-function board 602 to move downward, the L-shaped multi-function board 602 will not press the switch 607; when the micro-electric cylinder 603 drives the L-shaped multi-function board 602 to reset upward, the movable discharge pipe 502 automatically resets under the elastic force of the six spiral springs B506;When the heating tank 100 stops heating, the octagonal tube 201 moves downward under the action of gravity, and the eight groups of condensation components 303 automatically move inward under the action of the eight groups of spiral springs A306, which can automatically reduce the occupied space of the device and facilitate the turnover and transportation of the device. ;
