A steam condensation recovery and utilization device

Abstract

The present invention relates to the technical field of steam condensation, and specifically relates to a steam condensation recovery and utilization device, which includes a collection cylinder, a plugging disc and a regulating member. When connecting multiple heat exchangers to the collection cylinder at the same time, each connecting pipe is connected to one heat exchanger. When the weight of the condensed water discharged from any one heat exchanger entering the interior of the collection cylinder reaches a first preset weight, the regulating member can adjust the plugging disc to rotate a preset angle in the installation cavity, changing the discharge of condensed water from the heat exchanger into the collection cylinder. When the temperatures of the condensed water in multiple heat exchangers are different after heat exchange, the condensed water in different heat exchangers does not interfere with each other. Moreover, the weight of the condensed water discharged from each heat exchanger into the interior of the collection cylinder is the first preset weight, so the temperature of the condensed water after heat exchange in different heat exchangers does not interfere with the weight of the condensed water discharged into the interior of the collection cylinder, ensuring the stable operation of the recovered condensed water, and thus improving the recovery efficiency of the condensed water.

Description

Technical Field

[0001] The present invention relates to the technical field of steam condensation, and particularly relates to a steam condensation recovery and utilization device. Background Art

[0002] The wide application of steam in industrial production makes the effective treatment of steam condensate an important link in improving energy utilization efficiency and saving costs. During the heating process of steam heating equipment, steam will condense into condensate after heat exchange. If this condensate is not discharged or effectively recovered in time, it will have an adverse impact on the normal operation of the equipment and even cause energy waste. Most of the existing steam condensation recovery devices adopt a parallel drainage structure, connecting multiple heat exchangers to a steam condensation recovery device, and multiple drainage paths work in parallel. In the existing steam condensation recovery devices, although multiple drainage paths are in parallel, there is still physical connection in the structure. If the temperatures of the condensate in multiple heat exchangers are different after heat exchange, this physical connection will cause the high-temperature condensate to hinder the smooth discharge of the low-temperature condensate during the discharge process, resulting in low discharge efficiency of condensate at different temperatures and further affecting the recovery efficiency of condensate. Summary of the Invention

[0003] The present invention provides a steam condensation recovery and utilization device to solve the problem of low recovery efficiency of condensate in the existing steam condensation recovery devices.

[0004] The following technical scheme is adopted for a steam condensation recovery and utilization device of the present invention:

[0005] A steam condensation recovery and utilization device includes a collection cylinder, a sealing disk, and a regulating member.

[0006] The collection cylinder has an installation cavity inside. A plurality of connecting pipes communicating the external environment and the installation cavity are provided at the upper end of the collection cylinder. Each connecting pipe can be connected to a heat exchanger, and the plurality of connecting pipes are uniformly arranged around the circumferential direction of the upper end surface of the collection cylinder. The sealing disk is coaxially and rotatably arranged in the installation cavity. The upper end surface of the sealing disk can seal the plurality of connecting pipes. A through hole penetrating the upper and lower end surfaces of the sealing disk is provided on the sealing disk, and the through hole on the sealing disk can communicate with any one of the connecting pipes. The regulating member is used to adjust the sealing disk to rotate a preset angle in the installation cavity when the weight of the condensate discharged from any one of the heat exchangers entering the interior of the collection cylinder reaches a first preset weight, so as to change the discharge of condensate from the heat exchanger into the collection cylinder.

[0007] Further, a plurality of limiting blocks are arranged on the inner side wall of the collecting cylinder. Each limiting block can slide along the radial direction of the collecting cylinder. A first elastic member is arranged between each limiting block and the side wall of the collecting cylinder; each limiting block is arranged corresponding to a connecting pipe; a limiting groove is arranged on the plugging disc. Each limiting block can be inserted into the limiting groove. When the limiting block is inserted into the limiting groove, the through hole on the plugging disc communicates with a connecting pipe; the regulating member can drive the limiting block to disengage from the limiting groove.

[0008] Further, the regulating member includes a regulating shaft and a regulating rod. The regulating shaft is coaxially and rotatably connected to the plugging disc. The regulating rod is arranged along the radial direction of the regulating shaft. One end of the regulating rod is fixedly connected to the regulating shaft, and the other end of the regulating rod is provided with an extrusion inclined surface. When the regulating shaft rotates, the extrusion inclined surface of the regulating rod can extrude the limiting block to disengage from the limiting groove.

[0009] Further, the regulating member further includes a regulating torsion spring. The regulating torsion spring is arranged between the regulating shaft and the plugging disc. When the regulating shaft rotates relative to the plugging disc, the regulating torsion spring can store energy. During the process that the condensed water discharged from the heat exchanger enters the interior of the collecting cylinder, the regulating shaft gradually rotates.

[0010] Further, the regulating member further includes a water collecting bucket, a guiding disc and a transmission member. The guiding disc is fixedly arranged in the installation cavity. A guiding pipe is arranged in the middle of the guiding disc. The guiding disc can guide the condensed water discharged from the through hole into the interior of the guiding pipe; the water collecting bucket is arranged inside the guiding pipe. The water collecting bucket can slide up and down inside the guiding pipe. The transmission member is arranged between the water collecting bucket and the regulating shaft. When the water collecting bucket moves relative to the regulating shaft, through the transmission of the transmission member, the regulating shaft rotates.

[0011] Further, the transmission member includes a transmission sleeve; the transmission sleeve is coaxially sleeved inside the guiding pipe. The transmission sleeve is connected to the water collecting bucket through a connecting rod. When the transmission sleeve slides inside the guiding pipe, the transmission sleeve also rotates inside the guiding pipe. When the transmission sleeve rotates, it can drive the regulating shaft to rotate synchronously.

[0012] Further, a spiral protrusion is arranged on the outer side wall of the transmission sleeve, and a spiral groove is arranged on the inner side wall of the guiding pipe. The spiral protrusion is slidably arranged in the spiral groove; when the weight of the water collecting bucket increases, the transmission sleeve slides and rotates inside the guiding pipe.

[0013] Further, a ratchet tooth groove is arranged on the inner side wall of the transmission sleeve, and an elastic claw is arranged on the regulating shaft. The elastic claw can cooperate with the ratchet tooth groove to form a one-way transmission member. When the weight of the water collecting bucket increases, the rotation of the transmission sleeve inside the guiding pipe can drive the regulating shaft to rotate.

[0014] Further, a partition is provided in the middle in the axial direction of the condensate bucket; one end of the connecting rod is fixedly connected to the transmission sleeve, and the other end of the connecting rod is rotatably connected to the partition in the middle of the condensate bucket. When the condensate water inside the condensate bucket reaches the first preset weight, the condensate bucket can be turned over so that the condensate water inside the condensate bucket is separated from the condensate bucket; a return spring is provided between the transmission sleeve and the guiding pipe, and the return spring is used to drive the transmission sleeve to return to its original position.

[0015] Further, a protective sleeve is sleeved on the guiding pipe. The protective sleeve can prevent the condensate bucket from turning over when the condensate water inside the condensate bucket does not reach the first preset weight; the protective sleeve can slide on the guiding pipe, and the first preset weight of the condensate water in the condensate bucket can be adjusted.

[0016] The beneficial effects of the present invention are as follows: A steam condensation recovery and utilization device of the present invention includes a collection cylinder, a sealing plate and a regulating member. When connecting multiple heat exchangers to the collection cylinder at the same time, each connecting pipe is connected to one heat exchanger. Under the action of the sealing plate, only the condensate water in one heat exchanger can enter the interior of the collection cylinder. When the weight of the condensate water discharged from any one heat exchanger into the interior of the collection cylinder reaches the first preset weight, the regulating member can adjust the sealing plate to rotate a preset angle in the installation cavity, changing the discharge of condensate water from the heat exchanger into the collection cylinder. By setting the sealing plate and the regulating member, it is ensured that multiple heat exchangers can alternately transport condensate water into the collection cylinder. When the temperatures of the condensate water in multiple heat exchangers are different after heat exchange, the condensate water in different heat exchangers does not interfere with each other. Moreover, the weight of the condensate water discharged from each heat exchanger into the interior of the collection cylinder is the first preset weight, so the temperature of the condensate water after heat exchange in different heat exchangers will not interfere with the weight of the condensate water discharged into the interior of the collection cylinder, ensuring the stable operation of the recovered condensate water, and thus improving the recovery efficiency of the condensate water.

[0030] As Figures 1 to 8 shown, a steam condensation recovery and utilization device provided by an embodiment of the present invention includes a collection cylinder 110, a sealing disk 140 and a regulating member.

[0031] The collection cylinder 110 is cylindrical, the axis of the collection cylinder 110 is vertically arranged, the interior of the collection cylinder 110 is hollow, the hollow chamber inside the collection cylinder 110 is an installation cavity 111, and a plurality of connecting pipes 120 communicating the external environment and the installation cavity 111 are provided at the upper end of the collection cylinder 110, that is, the connecting pipes 120 penetrate through the upper end surface of the collection cylinder 110. Each connecting pipe 120 can communicate with a heat exchanger 130, and the condensed water discharged from the heat exchanger 130 can enter the installation cavity 111 through the connecting pipe 120. The plurality of connecting pipes 120 are uniformly arranged in the circumferential direction of the upper end surface of the collection cylinder 110. Among them, the number of connecting pipes 120 is the same as the number of heat exchangers 130. When the number of heat exchangers 130 is four, four connecting pipes 120 are provided, and the four connecting pipes 120 are uniformly distributed in the circumferential direction of the collection cylinder 110.

[0032] The plugging disc 140 is coaxially and rotatably arranged in the installation cavity 111. The upper end surface of the plugging disc 140 always abuts against the upper end surface of the inner side wall of the collecting cylinder 110. The upper end surface of the plugging disc 140 can plug a plurality of connecting pipes 120, and the plugging disc 140 can prevent the condensed water from entering the installation cavity 111 through the connecting pipes 120. A through hole 141 penetrating the upper and lower end surfaces of the plugging disc 140 is arranged on the plugging disc 140. The through hole 141 on the plugging disc 140 can communicate with any one of the connecting pipes 120. The number of the through holes 141 is one. When the through hole 141 communicates with one connecting pipe 120, the condensed water in the heat exchanger 130 connected to this connecting pipe 120 can enter the installation cavity 111, and the condensed water in the heat exchangers 130 connected to the remaining connecting pipes 120 cannot enter the installation cavity 111, preventing the condensed water in different heat exchangers 130 from interfering with each other.

[0033] The regulating member is used to adjust the plugging disc 140 to rotate a preset angle in the installation cavity 111 when the weight of the condensed water discharged from any one of the heat exchangers 130 into the inside of the collecting cylinder 110 reaches a first preset weight. When the plugging disc 140 rotates the preset angle, the connecting pipe 120 communicated with the through hole 141 changes, so that the heat exchanger 130 discharging the condensed water into the collecting cylinder 110 is changed, thereby ensuring that different heat exchangers 130 can all discharge the condensed water into the inside of the collecting cylinder 110. Further, the regulating member can adjust the plugging disc 140 to rotate a preset angle in the installation cavity 111. When the number of the connecting pipes 120 is four, the preset angle of rotation of the plugging disc 140 in the installation cavity 111 is ninety degrees. When the number of the connecting pipes 120 is two, the preset angle of rotation of the plugging disc 140 in the installation cavity 111 is one hundred and eighty degrees.

[0034] In a steam condensation recycling device of the present invention, when multiple heat exchangers 130 are connected to a collection tube 110 at the same time, each connecting pipe 120 is connected to a heat exchanger 130. Under the action of the blocking disk 140, condensed water in only one heat exchanger 130 among the multiple heat exchangers 130 can enter the interior of the collection tube 110. When the weight of condensed water discharged from any heat exchanger 130 entering the interior of the collection tube 110 reaches a first preset weight, the control unit can adjust the blocking disk 140 to rotate a preset angle in the installation cavity 111, thereby changing the heat exchanger 130 to discharge condensed water into the collection tube 110. Water, by setting a sealing plate 140 and a regulating control unit, it is ensured that multiple heat exchangers 130 can alternately transport condensed water to the inside of the collecting tube 110. When the temperatures of the condensed water are different after heat exchange in multiple heat exchangers 130, the condensed water in different heat exchangers 130 does not interfere with each other, and the weight of the condensed water discharged by each heat exchanger 130 to the inside of the collecting tube 110 is the first preset weight. Then, the temperature of the condensed water after heat exchange in different heat exchangers 130 will not interfere with the weight of the condensed water discharged to the inside of the collecting tube 110, thereby ensuring that the recovery of the condensed water can run smoothly, thereby improving the recovery efficiency of the condensed water.

[0035] In one embodiment, a plurality of stop blocks 150 are disposed on the inner side wall of the collection tube 110, each stop block 150 can slide along the radial direction of the collection tube 110, a first elastic member is disposed between each stop block 150 and the side wall of the collection tube 110, specifically, the first elastic member is a first spring 160, the axial direction of the first spring 160 is disposed in the radial direction of the collection tube 110, one end of the first spring 160 is fixedly connected to the inner side wall of the collection tube 110, and the other end of the first spring 160 is fixedly connected to the stop block 150. Each stop block 150 is disposed corresponding to a connecting tube 120, specifically, the number of the stop blocks 150 is the same as the number of the connecting tubes 120, and the plurality of stop blocks 150 are evenly distributed around the circumferential direction of the inner side wall of the collection tube 110. The blocking plate 140 is provided with a limiting groove, the number of which is one, and the limiting groove is provided on the peripheral side wall of the blocking plate 140. Each limiting block 150 can be inserted into the limiting groove. When the limiting block 150 is inserted into the limiting groove, the through hole 141 on the blocking plate 140 is connected with one connecting pipe 120, and the other connecting pipes 120 are blocked by the upper end surface of the blocking plate 140. When the weight of the condensed water discharged from any heat exchanger 130 entering the collecting tube 110 reaches a first preset weight, the control unit can drive the limiting block 150 to disengage from the limiting groove. At the same time, the blocking plate 140 can rotate a preset angle in the installation cavity 111. When the rotation angle of the blocking plate 140 reaches the preset angle, another limiting block 150 enters the limiting groove.

[0036] In one embodiment, the regulating member includes a regulating shaft 210 and a regulating rod 220. The regulating shaft 210 is coaxially and rotatably connected to the plugging disc 140. The regulating rod 220 is arranged along the radial direction of the regulating shaft 210. One end of the regulating rod 220 is fixedly connected to the regulating shaft 210, and the other end of the regulating rod 220 is provided with an extrusion inclined surface. When the regulating shaft 210 rotates, the extrusion inclined surface of the regulating rod 220 can extrude the limiting block 150 out of the limiting groove. Specifically, when any one of the limiting blocks 150 is in the limiting groove, the plugging disc 140 is in a relatively stationary state. At this time, the regulating shaft 210 rotates relative to the plugging disc 140, and the regulating rod 220 synchronously rotates relative to the plugging disc 140. Both the regulating rod 220 and the regulating shaft 210 are arranged below the plugging disc 140. By adjusting the thickness of the limiting block 150 in the vertical direction to be greater than the thickness of the plugging disc 140 in the vertical direction, it is ensured that the end of the regulating rod 220 far from the regulating shaft 210 can contact the limiting block 150. Since the end of the regulating rod 220 far from the regulating shaft 210 is an extrusion inclined surface, when the regulating rod 220 rotates relative to the plugging disc 140, the extrusion inclined surface of the regulating rod 220 can contact the limiting block 150. As the regulating rod 220 further rotates, the extrusion inclined surface on the regulating rod 220 extrudes the limiting block 150 out of the limiting groove.

[0037] In one embodiment, the regulating member further includes a regulating torsion spring 230. The regulating torsion spring 230 is arranged between the regulating shaft 210 and the plugging disc 140. Specifically, the axis of the regulating torsion spring 230 is the same as the axis direction of the regulating shaft 210. One end of the regulating torsion spring 230 is fixedly connected to the plugging disc 140, and the other end of the regulating torsion spring 230 is fixedly connected to the regulating shaft 210. When the regulating shaft 210 rotates relative to the plugging disc 140, the regulating torsion spring 230 can store energy. In the initial state, the regulating torsion spring 230 is in a state of not storing energy. During the process of the condensed water discharged from the heat exchanger 130 entering the inside of the collecting cylinder 110, the regulating shaft 210 gradually rotates. When the weight of the condensed water discharged from the heat exchanger 130 and entering the inside of the collecting cylinder 110 reaches the first preset weight, the regulating shaft 210 rotates a preset angle. When the number of heat exchangers 130 is four, the preset angle of rotation of the regulating shaft 210 is ninety degrees. The regulating torsion spring 230 stores energy, and the rotation angle of the regulating rod 220 is also ninety degrees. When the regulating rod 220 rotates ninety degrees, the regulating rod 220 extrudes the limiting block 150 out of the limiting groove. Subsequently, the regulating torsion spring 230 releases energy, and the regulating torsion spring 230 can quickly drive the plugging disc 140 to rotate ninety degrees in the installation cavity 111. Then, the through holes 141 on the plugging disc 140 quickly change the connected connecting pipes 120, so as to change the discharge of condensed water from the heat exchanger 130 into the collecting cylinder 110. Under the action of the regulating torsion spring 230, the rotation duration of the plugging disc 140 is shortened, the time interval for changing the discharge of condensed water from the heat exchanger 130 is reduced, and thus the recovery efficiency of the condensed water is improved.

[0038] In one embodiment, the regulating member further includes a water collecting bucket 310, a guiding disk 320 and a transmission member. The guiding disk 320 is fixedly arranged in the installation cavity 111. The guiding disk 320 is in a flared shape with an upward opening. The condensed water entering the installation cavity 111 can fall on the guiding disk 320. According to the shape of the guiding disk 320, the condensed water falling on the guiding disk 320 can be concentrated in the middle of the guiding disk 320. A guiding pipe 330 is arranged in the middle of the guiding disk 320. The guiding pipe 330 is coaxially arranged with the guiding disk 320. The guiding pipe 330 penetrates through the guiding disk 320. The condensed water falling on the guiding disk 320 can enter the interior of the guiding pipe 330. The water collecting bucket 310 is arranged inside the guiding pipe 330. The water collecting bucket 310 can slide up and down inside the guiding pipe 330. In the initial state, there is no condensed water in the water collecting bucket 310, and the water collecting bucket 310 and the guiding pipe 330 are in a relatively static state. As the condensed water enters the interior of the water collecting bucket 310, the overall weight of the water collecting bucket 310 increases, and the water collecting bucket 310 moves relative to the guiding pipe 330 under the action of its own gravity. The transmission member is arranged between the water collecting bucket 310 and the regulating shaft 210. When the water collecting bucket 310 moves relative to the regulating shaft 210, through the transmission of the transmission member, the regulating shaft 210 rotates. When the weight of the condensed water discharged from the heat exchanger 130 into the interior of the water collecting bucket 310 reaches the first preset weight, the moving distance of the water collecting bucket 310 relative to the regulating shaft 210 is constant, and through the transmission of the transmission member, the rotating angle of the regulating shaft 210 is constant, so as to ensure that the weight of the condensed water discharged from each heat exchanger 130 into the interior of the water collecting bucket 310 is the first preset weight.

[0039] In one embodiment, the transmission member includes a transmission sleeve 340 coaxially sleeved inside the guiding tube 330. The transmission sleeve 340 is connected to the water collecting bucket 310 through a connecting rod 370. The connecting rod 370 is vertically arranged, with its upper end connected to the transmission sleeve 340 and its lower end connected to the water collecting bucket 310. When there is no condensed water in the water collecting bucket 310, the water collecting bucket 310 is in a relatively stationary state inside the guiding tube 330. When the condensed water in the water collecting bucket 310 gradually increases, the weight of the water collecting bucket 310 increases, and the water collecting bucket 310 moves relative to the guiding tube 330. The movement of the water collecting bucket 310 drives the transmission sleeve 340 to move simultaneously through the connecting rod 370. When the transmission sleeve 340 slides inside the guiding tube 330, the transmission sleeve 340 rotates simultaneously inside the guiding tube 330. Specifically, spiral protrusions are provided on the outer sidewall of the transmission sleeve 340, and spiral grooves are provided on the inner sidewall of the guiding tube 330. The spiral protrusions are slidably arranged in the spiral grooves. When the weight of the water collecting bucket 310 increases, the transmission sleeve 340 slides and rotates inside the guiding tube 330. While the transmission sleeve 340 rotates, the water collecting bucket 310 rotates synchronously inside the guiding tube 330. When the transmission sleeve 340 rotates, it drives the regulation shaft 210 to rotate synchronously. Further, when the weight of the condensed water in the water collecting bucket 310 reaches the first preset weight, the condensed water in the water collecting bucket 310 can be discharged from the water collecting bucket 310 in time.

[0040] In one embodiment, ratchet grooves 350 are provided on the inner sidewall of the transmission sleeve 340, and the ratchet grooves 350 are arranged circumferentially around the inner sidewall of the transmission sleeve 340. Elastic pawls 360 are provided on the regulation shaft 210, and the elastic pawls 360 can cooperate with the ratchet grooves 350 to form a one-way transmission member. When the weight of the water collecting bucket 310 increases, the transmission sleeve 340 rotates and moves downward relative to the guiding tube 330. At this time, the elastic pawls 360 cannot move relative to the ratchet grooves 350. Then, the rotation of the transmission sleeve 340 is transmitted to the regulation shaft 210 through the transmission of the elastic pawls 360 and the ratchet grooves 350, causing the regulation shaft 210 to rotate. At this time, there is relative movement between the regulation shaft 210 and the transmission sleeve 340 in the axial direction. By setting the length of the ratchet grooves 350 in the axial direction, it is ensured that the elastic pawls 360 are always inside the ratchet grooves 350.

[0041] In one embodiment, a partition 311 is provided in the middle of the water collecting bucket 310 in the axial direction. Specifically, the water collecting bucket 310 is provided with a through hole in the up and down direction. A partition 311 is provided in the middle of the water collecting bucket 310. The partition 311 is fixedly connected to the inner side wall of the water collecting bucket 310. When the water collecting bucket 310 is in a vertical state, the partition 311 can divide the interior of the water collecting bucket 310 into two relatively isolated chambers. One end of the connecting rod 370 is fixedly connected to the transmission sleeve 340, and the other end of the connecting rod 370 is rotatably connected to the partition 311 in the middle of the water collecting bucket 310. When the condensed water inside the water collecting bucket 310 reaches the first preset weight, the water collecting bucket 310 can be turned over so that the condensed water inside the water collecting bucket 310 is separated from the water collecting bucket 310. When the condensed water inside the water collecting bucket 310 is separated from the water collecting bucket 310, the weight of the water collecting bucket 310 decreases. To ensure that after the heat exchanger 130 is replaced and condensed water is transported into the water collecting bucket 310, and to ensure that the weight of the condensed water discharged from each heat exchanger 130 into the water collecting bucket 310 is the first preset weight, at this time, the transmission sleeve 340 needs to return to its initial position. However, at this time, the control shaft 210 does not need to rotate in the reverse direction. Therefore, a return spring 380 is provided between the transmission sleeve 340 and the guiding pipe 330. The return spring 380 is used to drive the transmission sleeve 340 to return to its original position. Specifically, the return spring 380 is coaxially arranged with the transmission sleeve 340. The upper end of the return spring 380 is fixedly connected to the guiding pipe 330, and the lower end of the return spring 380 is fixedly connected to a connecting ring. The connecting ring is rotatably connected to the transmission sleeve 340 to prevent the return spring 380 from hindering the rotation of the transmission sleeve 340. When the return spring 380 drives the transmission sleeve 340 to return to its original position, the transmission sleeve 340 moves upward relative to the guiding pipe 330. Under the cooperation of the spiral protrusion and the spiral groove, the transmission sleeve 340 rotates in the reverse direction. At the same time, under the action of the elastic claw 360 and the ratchet groove 350, the control shaft 210 remains stationary.

[0042] In one embodiment, a protective sleeve 410 is sleeved on the guiding pipe 330, and the protective sleeve 410 can prevent the water collecting bucket 310 from tipping over when the condensate water inside has not reached the first preset weight. Specifically, the protective sleeve 410 is coaxially arranged with the guiding pipe 330. When the condensate water inside the water collecting bucket 310 reaches the first preset weight, the upper end of the water collecting bucket 310 disengages from the lower end of the protective sleeve 410, and the protective sleeve 410 no longer hinders the tipping of the water collecting bucket 310. The reason for the tipping of the water collecting bucket 310 is the offset of the center of gravity of the water collecting bucket 310. Further, the protective sleeve 410 can slide on the guiding pipe 330, and the first preset weight of the condensate water in the water collecting bucket 310 can be adjusted. It is easy to understand that when the upper end of the water collecting bucket 310 disengages from the lower end of the protective sleeve 410, the protective sleeve 410 does not hinder the tipping of the water collecting bucket 310. By sliding the protective sleeve 410 on the guiding pipe 330, when the upper end of the water collecting bucket 310 disengages from the lower end of the protective sleeve 410, the distance that the water collecting bucket 310 moves downward can be changed. The reason for the downward movement of the water collecting bucket 310 is that the condensate water inside the water collecting bucket 310 gradually increases, so as to realize the adjustment of the first preset weight of the condensate water in the water collecting bucket 310. Further, the first preset weight also needs to be adjusted in combination with the number of heat exchangers 130 to ensure that the force stored in the regulating torsion spring 230 when the regulating shaft 210 rotates is sufficient to drive the sealing disc 140 to rotate a preset angle.

[0043] In one embodiment, for the convenience of adjusting the protective sleeve 410, the guiding pipe 330 penetrates through the lower end surface of the collecting cylinder 110. The protective sleeve 410 is arranged outside the installation cavity 111, and the water collecting bucket 310 is arranged outside the installation cavity 111. The condensate water discharged from the water collecting bucket 310 can be directly conveyed to the external environment.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
