Description

Technical Field

[0001] The utility model relates to the technical field of gas heating, in particular to a condensed water collecting device and a gas heating hot water boiler having the same. Background Art

[0002] In condensing gas heating hot water boilers, a condensing heat exchanger is generally installed to fully cool the combustion flue gas, so that the water vapor in the flue gas can fully condense and release the heat therein. The flue gas is then discharged from the smoke pipe after heat exchange with the cold air outside, thereby maximizing the heat exchange efficiency. However, since the flue gas contains sulfur components, sulfides such as sulfur dioxide produced after combustion dissolve in the condensed water, causing the condensed water to contain sulfuric acid, sulfurous acid and other substances. Therefore, during operation, the condensed water is not allowed to leak out from the condensed water channel in the heat exchanger.

[0003] In the prior art, a condensate collection device is used to collect the condensate before discharging it. In order to prevent the flue gas from being discharged from the condensate collection device together with the condensate, the condensate collection device is configured in the form of a water seal and a float. When the condensate height in the condensate collection device is insufficient, the float is used to close the condensate inlet channel. When a certain height of condensate is stored in the condensate collection device, the float floats up under the action of the condensate, and the condensate inlet channel is closed in the form of a water seal. However, after the condensing gas heating water boiler has been used for a long time, the oil stains and dirt in the flue gas will accumulate in the condensate collection device, causing the float to stick to the inner wall of the condensate inlet channel, blocking the condensate from flowing in the condensate inlet channel, and making it impossible for the condensate to be discharged. At this time, if the condensate flows back to the burner, it will cause the condensing gas heating water boiler to shut down, or even damage the burner. Utility Model Content

[0004] The first technical problem solved by the utility model is to provide a condensate collecting device, which effectively improves the stability of the operation of the condensate collecting device when the condensing gas heating water boiler is used for a long time, and ensures that the condensate collecting device can be closed to collect the condensate when the condensate is less, and can automatically open to discharge part of the condensate when the condensate is more.

[0005] The second technical problem to be solved by the utility model is to provide a gas heating water heater, which, when used for a long time, can ensure that condensed water can be used to achieve a water seal and prevent condensed water from flowing back into the burner, thereby effectively improving the operating stability of the gas heating water heater during long-term use.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] A condensed water collection device for a gas-fired heating water heater, comprising:

[0008] The water collecting member is provided with a cavity, a partition is provided in the cavity of the water collecting member, the partition is provided with a sealing port, the partition divides the cavity into a water collecting cavity and a water discharging cavity, and the water collecting member is provided with a fluid inlet communicating with the water collecting cavity and a fluid outlet communicating with the water discharging cavity;

[0009] The force-applying member is installed in the water discharge cavity. A sealing member is installed between the force-applying member and the sealing port. The force-applying member is suitable for applying a thrust toward the sealing port to the sealing member so that the sealing member abuts against the partition and seals the sealing port.

[0010] Compared with the background technology, the condensate collection device described in the utility model has the following beneficial effects: the condensate collection device is installed in a gas heating hot water boiler for use, and is used to collect and discharge condensate, and uses the collected condensate to form a water seal to prevent smoke from being discharged with the condensate. In the initial state, the seal is abutted and sealed with the sealing port on the partition under the thrust of the force-applying member, so that the sealing port is in a closed state. When collecting condensate, the condensate enters the water collection chamber from the fluid inlet on the water collection member. As the condensate gradually accumulates in the water collection chamber, when the overall gravity of the condensate and the seal is greater than the thrust of the force-applying member, the sealing port is converted to an open state, and the seal is separated from the sealing port. At this time, the condensate can flow from the sealing port into the drain chamber and be discharged from the fluid outlet of the drain chamber. When the overall gravity of the remaining condensate and the seal is less than the thrust of the force-applying member, the seal is abutted and sealed with the sealing port on the partition again under the thrust of the force-applying member, so that the sealing port is closed again. The sealing port and the sealing member are arranged at the bottom of the condensate, and the state of the sealing member is automatically controlled by utilizing the gravity of the condensate and the thrust of the force-applying member. Even if smoke enters the water collecting chamber, due to the isolation of the condensate, the smoke stains and dust in the smoke will only accumulate above the condensate in the water collecting chamber, but will not adhere to the sealing member below the condensate, without affecting the movement of the sealing member. This ensures that the condensate collection device will not leak smoke or water and will operate stably when the gas heating water heater is used for a long time.

[0011] In one embodiment, the partition is a conical tube, the end of the conical tube with a larger opening area is arranged toward the water collecting chamber, and the sealing port is arranged at the end of the conical tube with a smaller opening area.

[0012] In one embodiment, an abutting inner chamfer is provided at one end of the sealing opening facing the sealing member, a surface of the sealing member facing the sealing opening is matched with the shape of the abutting inner chamfer, and the sealing member is suitable for abutting and sealing with the abutting inner chamfer.

[0013] In one embodiment, the water collecting part includes a water collecting cylinder body, and a water seal upper cover and a water seal lower cover are detachably installed at both ends of the water collecting cylinder body, the fluid inlet is arranged on the water seal upper cover, the fluid outlet is arranged on the water seal lower cover, and the sealing port is arranged in the water collecting cylinder body.

[0014] In one of the embodiments, a guide cylinder is provided in the water seal lower cover, the force applying member is fixedly installed in the guide cylinder, and the sealing member is slidably installed in the guide cylinder.

[0015] In one embodiment, the sealing member includes a sliding portion and an abutting portion, the outer diameter of the abutting portion is larger than the outer diameter of the sliding portion, the sliding portion is slidably mounted in the guide cylinder, and the abutting portion is suitable for abutting and cooperating with the sealing port.

[0016] In one of the embodiments, a disassembly opening is provided at one end of the guide tube away from the sealing opening, and a disassembly cover is detachably mounted on the disassembly opening.

[0017] In one of the embodiments, the water seal upper cover is threadedly matched with the water collecting cylinder body; and / or the water seal lower cover is threadedly matched with the water collecting cylinder body.

[0018] In one embodiment, the force applying member is a first magnet, the sealing member is a second magnet or the sealing member is provided with a second magnet, and the first magnet and the second magnet have opposite magnetic poles on a surface facing each other.

[0019] In one embodiment, the force-applying member is an elastic member, the sealing member is a sealing block, and the elastic member is in a compressed state to apply a thrust to the sealing block toward the sealing port.

[0020] The above second technical problem is solved by the following technical solution:

[0021] A gas heating hot water boiler comprises a boiler body and the condensed water collecting device described in the utility model.

[0022] Compared with the background technology, the gas heating water heater described in the utility model has the following beneficial effects: when the gas heating water heater is in long-term operation, the condensate collection device can ensure that there will be no smoke or water leakage, and prevent the flameout or burner damage caused by the condensate flowing back to the burner, thereby ensuring the stable operation of the gas heating water heater.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1

[0034] Figures 1 to 4 The condensed water collecting device provided in this embodiment is shown, which is used to be installed on a gas heating water heater to collect condensed water in the flue gas. The condensed water collecting device includes a water collecting member and a force applying member 9.

[0035] The water collecting member is provided with a cavity, a partition is provided in the inner cavity of the water collecting member, a sealing port 4 is provided on the partition, the partition divides the cavity of the water collecting member into a water collecting chamber 5 and a water discharge chamber 6, and the water collecting member is provided with a fluid inlet 7 communicating with the water collecting chamber 5 and a fluid outlet 8 communicating with the water discharge chamber 6. A force-applying member 9 is installed in the water discharge chamber 6, a sealing member 10 is installed between the force-applying member 9 and the sealing port 4, and the force-applying member 9 is suitable for applying a thrust to the sealing member 10 toward the sealing port 4, so that the sealing member 10 slides along the thrust direction of the force-applying member 9, thereby making the sealing member 10 abut against the partition and sealing the sealing port on the partition.

[0036] The condensate collection device is installed in a gas heating water heater for use, and is used to collect and discharge condensate, and use the collected condensate to form a water seal to prevent smoke from being discharged with the condensate. In the initial state, the seal 10 is sealed against the sealing port 4 on the partition under the thrust of the force member 9, so that the sealing port remains in a closed state. When collecting condensate, the condensate enters the water collection chamber 5 from the fluid inlet 7 on the water collection member. As the condensate gradually accumulates in the water collection chamber 5, when the overall gravity of the condensate and the seal 10 is greater than the thrust of the force member 9, the seal 10 is separated from the sealing port 4, and the sealing port 4 is converted to an open state. At this time, the condensate can flow from the sealing port 4 into the drain chamber 6 and be discharged from the fluid outlet 8 connected to the drain chamber 6. When the overall gravity of the remaining condensate and the seal 10 is less than the thrust of the force member 9, the seal 10 is sealed against the sealing port 4 on the partition again under the thrust of the force member 9, so that the sealing port 4 is closed again. The sealing port 4 and the sealing member 10 are arranged at the bottom of the condensate, and the state of the sealing member 10 is automatically controlled by utilizing the gravity of the condensate and the thrust of the force-applying member 9. Even if smoke enters the water collecting chamber 5, due to the isolation of the condensate, the smoke stains and dust in the smoke will only accumulate above the condensate in the water collecting chamber 5, and will not affect the sealing member 10 below the condensate, thereby ensuring that the condensate collection device will not leak smoke or water and will operate stably when the gas heating water heater is used for a long time.

[0037] In order to ensure that the condensed water can smoothly flow out of the sealing port 4 when the sealing member 10 is separated from the sealing port 4 on the partition so that the sealing port is opened, and to prevent the dust deposited in the condensed water from accumulating at the sealing port 4 and causing the sealing port 4 to be blocked, the partition in this embodiment is set as a conical cylinder 11, and the end of the conical cylinder 11 with a larger opening area is set toward the water collecting chamber 5, and the sealing port 4 is set at the end of the conical cylinder 11 with a smaller opening area. In order to ensure the sealing performance of the sealing member 10 and the sealing port 4, an abutting inner chamfer 12 is set at the end of the sealing port 4 facing the sealing member 10, and the side of the sealing member 10 facing the sealing port 4 is adapted to the shape of the abutting inner chamfer 12. When the sealing member 10 cooperates with the sealing port 4 to close the sealing port 4, the sealing member 10 extends into the abutting inner chamfer 12 and abuts against the abutting inner chamfer 12 for sealing. In some other embodiments, the partition can be provided with a partition plate, and the sealing port 4 is provided on the partition plate.

[0038] The water collecting part can be an integrally formed structural part or a split structural part. In order to facilitate daily maintenance of the water collecting part in this embodiment, the water collecting part is set to be split. The water collecting part includes a water collecting cylinder body 1, and the two ends of the water collecting cylinder body 1 are respectively detachably mounted with a water seal upper cover 2 and a water seal lower cover 3, a fluid inlet 7 is arranged at the top of the water seal upper cover 2, a fluid outlet 8 is arranged at the bottom of the water seal lower cover 3, and a partition is arranged in the water collecting cylinder body 1. The water seal upper cover 2 and the water seal lower cover 3 are both threadedly matched with the water collecting cylinder body 1.

[0039] In order to limit the thrust direction of the force-applying member 9 and the movement direction of the sealing member 10 in the water discharge chamber 6, a guide cylinder 13 is provided in the water seal lower cover 3, the force-applying member 9 is fixedly installed in the guide cylinder 13, and the sealing member 10 is slidably installed in the guide cylinder 13. In order to prevent the sealing member 10 from being stuck in the guide cylinder 13 by accumulated dust, the sealing member 10 includes a sliding portion and an abutting portion, the outer diameter of the abutting portion is larger than the outer diameter of the sliding portion, and the sliding portion is slidably installed in the guide cylinder 13. The outer diameter of the sliding portion is smaller than the inner diameter of the guide cylinder 13, the outer diameter of the bottom of the abutting portion is larger than the inner diameter of the guide cylinder 13, and the top of the abutting portion is set to an outer chamfered cone shape that matches the shape of the abutting inner chamfer 12, so as to abut with the abutting inner chamfer 12 to achieve abutment sealing of the sealing port 4.

[0040] One end of the guide cylinder 13 away from the sealing port 4 extends to the bottom of the water seal lower cover 3, and a disassembly port is provided at the bottom of the guide cylinder 13, and a disassembly cover 14 is detachably mounted on the disassembly port. In this embodiment, the disassembly cover 14 is threadedly matched with the bottom of the guide cylinder 13 to seal. In some other embodiments, the disassembly cover 14 is snap-fitted with the guide cylinder 13 to achieve the sealing of the disassembly port. After the disassembly cover 14 is lowered, the force-applying member 9 can be taken out from the disassembly port, and the force-applying member 9 can be replaced or repaired, and the dirt accumulated in the guide cylinder 13 can be cleaned, which is convenient for later maintenance and cleaning, and avoids the accumulation of dirt affecting the normal movement of the force-applying member 9 and the sealing member 10.

[0041] The force-applying member 9 is a first magnet, which can be a permanent magnet or an electromagnet. In this embodiment, a permanent magnet is selected. The sealing member 10 is a second magnet or a second magnet is provided on the sealing member 10, and the second magnet is a permanent magnet. The magnetic poles of the first magnet and the second magnet facing each other are opposite. By cooperating with the second magnet as the sealing member 10 and the first magnet as the force-applying member 9, the active sealing of the sealing port 4 in the cavity of the water collecting member is realized, which can effectively prevent smoke leakage. When the condensed water in the water collecting cavity 5 above the sealing port 4 in the water collecting member reaches a certain height, when the overall gravity of the condensed water and the second magnet is greater than the magnetic force applied by the first magnet to the second magnet, the second magnet moves downward, and the condensed water flows out from the gap between the sealing port 4 and the second magnet. Since the water seal lower cover 3 is threadedly matched with the water collecting barrel body 1, the water seal lower cover 3 can be removed from the bottom of the water collecting barrel body 1, and the seal 10 and the force-applying member 9 can be removed together after the water collecting barrel body 1 is disassembled. When the first magnet serving as the force applying member 9 or the second magnet serving as the sealing member 10 loses its magnetism due to some reasons, it can be removed, re-magnetized, and reused.

[0042] As an alternative embodiment, the force-applying member 9 can also be a spring serving as an elastic member, and the sealing member 10 is a sealing block. The elastic member is in a compressed state to apply a thrust toward the sealing port 4 to the sealing block. In order to ensure the corrosion resistance of the force-applying member 9 and the sealing member 10, the spring and the sealing block are both made of stainless steel. When the gravity of the condensed water and the sealing block is greater than the initial elastic force of the spring, the sealing block and the spring are pressed downward, the spring is further compressed, the sealing block moves downward, and the condensed water flows out from the gap between the sealing blocks.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
