Specifically, the upper chamber 128 of the present embodiment is in communication with the water outlets 122 of the tray 113, and the lower chamber 129 is in communication with the inlet 126 of the drain channel 125.

The partitioning member 13 includes a guiding tube body 131 and a partitioning plate body 132. The draft tube body 131 has a top end 133 and a bottom end 134 opposite the top end 133. The flow guiding tube body 131 is formed with a through hole 135 extending in an up-and-down direction D and extending through the top end 133 and the bottom end 134. The through hole 135 has an upper opening 136 at the top end 133, and a bottom end 134 and The lower opening 137 is connected to the lower chamber 129. The draft tube body 131 is formed with a plurality of flow guiding holes 138 which are spaced apart from each other and arranged in a ring shape and communicate with the through holes 135. The flow guiding holes 138 can communicate with the upper chamber 128. Each diversion hole 138 is The long shape and the long direction thereof extend along the up-and-down direction D. Each of the flow guiding holes 138 has a lower end portion 139 spaced above the bottom end 134, and an upper end portion 140 spaced apart below the top end 133, the upper end portion of the embodiment 140 is a closed end. Each of the flow guiding holes 138 has an inverted triangular shape, and the width of each of the flow guiding holes 138 is gradually increased from the lower end portion 139 toward the upper end portion 140.

The partition plate body 132 is integrally formed on the outer peripheral surface of the draft tube body 131 and spaced apart below the flow guiding hole 138. The partition body 132 has a substrate portion 141 adjacent to the bottom end 134, and a convex ring portion 142 projecting upward from the top surface of the substrate portion 141 and adjacent to the lower end portion 139 of the flow guiding hole 138. The substrate portion 141 is fixedly coupled to the inner surface of the cylindrical member 111 by, for example, snapping or screwing, and the substrate portion 141 is formed with a through hole 143 through which the bottom end of the water supply pipe 115 is bored.

The buoyancy device 2 includes a pontoon 21 that is sleeved on the draft tube body 131 and serves to shield the flow guiding hole 138. The pontoon 21 includes a bottom wall 211, a cylinder 212, and a mask 213. The bottom wall 211 has an annular shape for contacting the convex ring portion 142 of the partition plate body 132, and the bottom wall 211 is spaced apart from the substrate portion 141 by a distance. The cylinder 212 protrudes from the outer periphery of the bottom wall 211 , and the mask 213 protrudes from the inner circumference of the bottom wall 211 and is spaced apart from the cylinder 212 . The bottom wall 211, the barrel 212, and the mask 213 collectively define an interior space 214. The mask 213 is disposed on the guiding tube body 131 and shields the respective opening 136 of the guiding hole 138 and the through hole 135. The pontoon 21 is movable relative to the partition 13 in the up-and-down direction D by the buoyancy generated by the condensed water 5 flowing into the upper chamber 128, and the mask 213 of the pontoon 21 can follow The flow rate of the condensed water 5 is correspondingly adjusted to cover the extent of the respective flow guiding holes 138, and the extent to which each of the flow guiding holes 138 communicates with the upper chamber 128. Thereby, the flow rate of the condensed water 5 into the lower chamber 129 through the respective flow holes 138 and the through holes 135 can be controlled.

By designing the convex ring portion 142 of the partitioning plate 132, the bottom surface of the bottom wall 211 of the pontoon 21 is only in contact with the top surface of the convex ring portion 142 adjacent to the mask 213, and the bottom surface of the bottom wall 211 is adjacent to the cylindrical body 212. The portion is spaced apart from the substrate portion 141 by a distance. Thereby, the condensed water 5 can flow into a gap 215 between the bottom wall 211 and the substrate portion 141 and move the buoy 21 up by buoyancy. Through the foregoing design, the bottom surface of the bottom wall 211 can be prevented from being completely attached directly to the top surface of the substrate portion 141, so as to prevent the bottom surface of the bottom wall 211 from being affected by the viscous force of the condensed water 5, thereby causing the pontoon 21 to move upwards smoothly.

The bottom wall 211 of the pontoon 21 is formed with a plurality of openings 216 corresponding to the substrate portion 141, and each of the openings 216 is in communication with the internal space 214 and the upper chamber 128. The condensed water can flow into the internal space 214 through the gap 215 and the opening 126, whereby the flow path of the condensed water 5 in the hollow casing 11 can be increased, so that the condensed water 5 has a sufficient time to lower the temperature.

More specifically, in the present embodiment, the lower wall 119 of the carrier tray 113 is formed with a guide hole 130 corresponding to the lower side of the water inlet hole 116. The buoyancy device 2 further includes a central cylinder 22 fixedly coupled to the center of the cylinder 212 and the center of the shield 213. The central cylinder 22 is disposed in the guiding hole 130, and the guiding hole 130 is used to guide the central cylinder 22. Move in the up and down direction D. Guided by the design of the central cylinder 22 in the guiding hole 130 The movement direction of the pontoon 21 is restricted, the pontoon 21 can be smoothly moved in the up and down direction D, and the pontoon 21 can be prevented from being shaken during the movement.

The non-return device 3 is disposed in the drain flow passage 125 and is movable when the pressure in the lower chamber 129 exceeds a certain value to allow the lower chamber 129 to communicate with the drain passage 125. The check device 3 includes two ball plungers 31 disposed in the drain flow channel 125 and stacked one on top of the other, and a stop rail 32 disposed in the drain flow channel 125 and fixedly coupled to the drain pipe 115. The blocking crossbar 32 is located between the ball plunger 31 and the outlet 127, and the blocking crossbar 32 is used to block the upper ball plunger 31 to limit the height of its upward movement, thereby preventing the ball plunger 31 from being detached from the drainage flow via the outlet 127. Road 125. In the normal state, the two ball plugs 31 are subjected to gravity so that the lower ball plug 31 abuts against a shoulder 110 of the drain pipe 115 and blocks the inlet 126. When the pressure in the lower chamber 129 exceeds a certain value, the condensed water 5 in the lower chamber 129 pushes the two ball stoppers 31 upward, moving the lower ball plug 31 away from the shoulder portion 110 to open the inlet 126. Thereby, the condensed water 5 can flow into the drain flow path 125 via the inlet 126 and be discharged through the outlet 127.

Referring to FIGS. 2 and 3, the vacuum eliminating device 4 is disposed in the vacuum eliminating hole 118 of the top cover 112. The vacuum eliminating device 4 includes a valve body 41, a plug member 42, and a spring 43. The valve body 41 is fixed in the vacuum elimination hole 118 and defines a gas passage 411 communicating with the upper chamber 128, and a plurality of intake holes 412 communicating between the gas passage 411 and the external environment. The plug 42 is disposed in the gas passage 411 for abutting against a shoulder 413 of the valve body 41 to block the gas passage 411. Spring 43 is disposed in the gas passage The 411 is used to apply an elastic force to the plug 42 toward the shoulder 413. In the normal state, the spring force applied to the plug member 42 by the spring 43 causes the plug member 42 to be positioned at a blocking position against the shoulder portion 413 to block the gas passage 411. When the pressure in the upper chamber 128 is less than the pressure outside the outer casing 1, the gas outside the outer casing 1 flows into the gas passage 411 via the air inlet hole 412 and pushes the plug member 42 downward to a position separated from the shoulder portion 413 to make the gas The passage 411 is in an open state, whereby the vacuum state in the upper chamber 128 is eliminated.

Referring to FIG. 2 and FIG. 4, when the steam decanter 100 is in operation, the high temperature condensed water 5 generated in the steam system flows into the accommodating tank 121 through the water inlet hole 116, and then the condensed water 5 passes through the filter tube 114. The filter holes 123 and the water outlet holes 122 flow into the upper chamber 128 and are accumulated in the upper chamber 128. By the arrangement of the filter tubes 114, the coarse impurities in the condensed water 5 can be filtered, and the coarse impurities are accumulated in the region surrounded by the filter tubes 114.

As the amount of condensed water 5 in the upper chamber 128 gradually increases, the condensed water 5 flows into the internal space 214 through the gap 215 and the opening 216, and at the same time, the condensed water 5 gradually lifts the pontoon 21 upward. When the mask 213 of the pontoon 21 is moved to a position where the respective flow guiding holes 138 are exposed and communicate with the upper chamber 128, the condensed water 5 accumulated in the upper chamber 128 flows through the respective flow guiding holes 138. Inside the hole 135 and through the through hole 135, it flows into the lower chamber 129. It should be noted that since the width of each of the flow guiding holes 138 is gradually increased from the lower end portion 139 toward the upper end portion 140, the more the condensed water 5 accumulated in the upper chamber 128, the higher the height at which the pontoon 21 is lifted. When high, each diversion hole 138 and upper The range in which the chambers 128 are connected will gradually increase. Thereby, the steam decanter 100 can automatically and gently adjust the flow rate of the discharged condensed water 5 to the lower chamber 129 according to the flow rate of the condensed water 5 in the upper chamber 128.

After the condensed water 5 flows into the upper chamber 128 via the inlet passage 124, the pontoon 21 is continuously moved upward. When the top surface of the cylinder 212 abuts against the bottom surface of the lower wall 119, the pontoon 21 is stopped by the lower wall 119 and cannot continue. Move up. The condensed water 5 continuously flowing into the upper chamber 128 continues to flow into the internal space 214 through the opening 216, so that the upper chamber 128 and the internal space 214 of the hollow casing 11 can accumulate a larger amount of condensed water 5. Thereby, the condensed water 5 can be sufficiently cooled to lower the temperature to avoid the problem of flashing steam generated after the high-temperature condensed water 5 is discharged.

When the condensed water 5 accumulates to a certain height and the pressure in the lower chamber 129 exceeds a certain value, the condensed water 5 in the lower chamber 129 pushes the two ball plugs 31 upward to urge the lower ball plug 31 to move away from the shoulder 110. The inlet 126 is opened. At this time, the lower chamber 129 communicates with the drain passage 125, and the condensed water 5 can flow into the drain passage 125 via the inlet 126. After the condensed water 5 flows into the drainage channel 125, the two ball plugs 31 are continuously moved upward. When the upper ball plug 31 is blocked by the blocking cross bar 32, the two ball plugs 31 cannot continue to move upward, and the condensed water 5 continues. The ground flows upward and is discharged through the outlet 127.

Referring to Fig. 5, which is a second embodiment of the steam decanter of the present invention, the overall structure and operation of the steam decanter 200 is substantially the same as that of the first embodiment, except for the detailed structure of the diversion tube body 131.

In the present embodiment, the upper end portion 140 of each of the flow guiding holes 138 is an open end formed at the top end 133. By the foregoing design, the flow guiding tube body 131 of the present embodiment can save the use of the manufacturing material compared with the first embodiment, thereby reducing the manufacturing cost.

In summary, the steam decanter 100, 200 of each embodiment is protruded from the dividing tube body 132 by the guiding tube body 131 of the partitioning member 13, and the mask 213 of the buoy 21 is sleeved on the diversion tube. The tubular body 131 and the shielding diversion hole 138 are designed such that the buoy 21 can be correspondingly adjusted in accordance with the flow rate of the condensed water 5 during the movement of the buoy 21 by the buoyancy generated by the condensed water 5 relative to the partition 13 The extent of each of the flow guiding holes 138 is shielded, and the size of each of the flow guiding holes 138 is communicated with the upper chamber 128. Thereby, the flow rate of the discharged condensed water 5 to the lower chamber 129 can be automatically and gently adjusted in accordance with the flow rate of the condensed water 5 in the upper chamber 128. In addition, the design of the condensed water 5 flowing into the internal space 214 can be provided by the opening 216 of the pontoon 21, so that the upper chamber 128 and the internal space 214 of the hollow casing 11 can accumulate a larger amount of condensed water 5. Thereby, the flow path of the condensed water 5 in the hollow casing 11 can be increased, and the condensed water 5 can have a sufficient time to lower the temperature.
