Description

Technical Field

[0001] This utility model relates to the field of heating and power supply technology, and in particular to a thermal deaerator. Background Technology

[0002] In the field of power auxiliary equipment, thermal deaerators are key equipment used to remove dissolved oxygen and other gases from boiler feedwater in order to protect thermal equipment and improve the operating efficiency and safety of thermal systems. Based on Henry's Law and Dalton's Law, the solubility of any gas in water is related to the partial pressure of the gas at the gas-water interface and the water temperature.

[0003] However, in existing technology, blockages in the outlet pipes of some devices can prevent water from draining properly from the deaerator, causing the water level to rise continuously. When the water level exceeds the normal range, it triggers the water level protection device, causing the deaerator-related equipment to shut down or take other protective measures, thus affecting the normal operation of the deaerator. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a thermal deaerator that ensures the smooth delivery of deoxygenated water to subsequent systems, maintains the normal operation of the thermal deaerator and the entire thermal system, avoids system failures and downtime due to pipe blockage, guarantees that all components of the deaerator operate under normal pressure and temperature conditions, prevents damage or failure of equipment components due to pressure fluctuations or leaks, ensures the stable operation of the deaerator and the entire thermal system, reduces the number of downtimes caused by equipment failures, and improves production efficiency.

[0005] To achieve the above objectives, a thermal deaerator is provided, comprising a base, a support block fixedly connected to the top of the base, a first tank fixedly connected to the top of the support block, a water outlet pipe fixedly connected to the bottom of the first tank, a first filter screen fixedly connected inside the water outlet pipe, a second filter screen fixedly connected inside the water outlet pipe, a water flow plate fixedly connected inside the water outlet pipe, a rotating shaft rotatably connected to the top of the water flow plate, multiple blades fixedly connected to the outside of the rotating shaft, and a fixing block fixedly connected to the bottom of the water outlet pipe.

[0006] According to the aforementioned thermal deaerator, a limiting circular block is slidably connected inside the fixed block, and a second drive rod is rotatably connected inside the limiting circular block. A second motor is fixedly connected to the output end of the second drive rod.

[0007] According to the aforementioned thermal deaerator, a tank cover is provided on the outside of the first tank body, a first motor is fixedly connected to the outside of the tank cover, a first drive rod is fixedly connected to the output end of the first motor, and a plurality of heating rods are fixedly connected to the outside of the first drive rod.

[0008] According to the aforementioned thermal deaerator, a filter cylinder is fixedly connected inside the first tank, a water inlet is fixedly connected to the top of the first tank, and a water storage tank is fixedly connected inside the water inlet.

[0009] According to the aforementioned thermal deaerator, a plurality of nozzles are fixedly connected to the bottom of the water storage tank, and a connecting pipe is fixedly connected to the outside of the water storage tank.

[0010] According to the aforementioned thermal deaerator, the tank cover is provided with a plurality of suction cups on its exterior, and a fixing plate is fixedly connected to the exterior of the suction cups.

[0011] According to the aforementioned thermal deaerator, a vent pipe is fixedly connected inside the fixed plate, and a second tank is fixedly connected to one end of the vent pipe.

[0012] According to the aforementioned thermal deaerator, a port is fixedly connected to the top of the second tank, and an observation window is provided inside the second tank.

[0013] Beneficial effects:

[0014] 1. Water is connected to an external water pipe and a connecting pipe. Water from the external water pipe flows into the water storage tank inside the outlet through the connecting pipe and is sprayed out through the nozzle at the bottom, thus entering the first tank. The first motor is then started, and driven by the first drive rod, it rotates the heating rod inside the first tank. Simultaneously, the heating rod itself generates heat to heat the water and remove oxygen. The water is then discharged through the bottom outlet pipe. During the discharge process, impurities may adhere to the inside of the outlet pipe. The impact force generated by the water discharge causes the internal rotating shaft to rotate, which in turn drives the blades outside the shaft to rotate, crushing the impurities in the water. Subsequently, driven by the second motor and the second drive rod, the limiting block inside the fixed block moves out of the groove inside the fixed block, discharging the water. This ensures that the deoxygenated water can be smoothly delivered to the subsequent system, maintaining the normal operation of the thermal deaerator and the entire thermal system, and avoiding system failures and downtime due to pipe blockage.

[0015] 2. Before deoxygenating the water, check the airtightness of the first tank. Connect the vent pipe and the fixing plate at one end to the tank cover using the suction cup. Insert the vent pipe into the first tank, then pour water into the second tank through the port. Insert one end of the vent pipe into the second tank so that it contacts the water inside. Observe through the observation window. If there is no reaction in the water inside the second tank, it means that the first tank is airtight. Conversely, if bubbles are generated, it means that the first tank is leaking and needs to be repaired by the operator. This ensures that all components of the deaerator operate under normal pressure and temperature conditions, avoiding damage or failure of equipment components due to pressure fluctuations, leaks, etc., ensuring the stable operation of the deaerator and the entire thermal system, reducing the number of downtimes caused by equipment failures, and improving production efficiency.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figures 1-4 This utility model provides a thermal deaerator, which includes a base 1, a support block 2 fixedly connected to the top of the base 1, a first tank 3 fixedly connected to the top of the support block 2, a water outlet pipe 17 fixedly connected to the bottom of the first tank 3, a first filter screen 20 fixedly connected inside the water outlet pipe 17, a second filter screen 21 fixedly connected inside the water outlet pipe 17, a water passage plate 22 fixedly connected inside the water outlet pipe 17, a rotating shaft 23 rotatably connected to the top of the water passage plate 22, a plurality of blades 24 fixedly connected to the outside of the rotating shaft 23, and a fixing block 25 fixedly connected to the bottom of the water outlet pipe 17.

[0026] Specifically: the water is discharged through the bottom outlet pipe 17. During the discharge process, impurities may adhere to the inside of the outlet pipe 17. At this time, the impact force generated by the discharge of water causes the internal rotating shaft 23 to rotate, thereby driving the blade 24 outside the rotating shaft 23 to rotate and crush the impurities in the water. Then, driven by the second motor 28 and in conjunction with the second drive rod 27, the limiting round block 26 inside the fixed block 25 moves out of the groove inside the fixed block 25 to discharge the water.

[0027] The fixed block 25 has a sliding connection to a limiting circle 26, the limiting circle 26 has a rotating connection to a second drive rod 27, and the output end of the second drive rod 27 is fixedly connected to a second motor 28.

[0028] The first tank body 3 is provided with a tank cover 4 on the outside. A first motor 11 is fixedly connected to the outside of the tank cover 4. A first drive rod 12 is fixedly connected to the output end of the first motor 11. Multiple heating rods 13 are fixedly connected to the outside of the first drive rod 12.

[0029] Specifically: the first motor 11 is started, and under the drive of the first motor 11, the heating rod 13 inside the first tank 3 is rotated in conjunction with the first drive rod 12. At the same time, the heating rod 13 heats the water to generate steam, thereby removing oxygen from the water.

[0030] A filter cylinder 14 is fixedly connected inside the first tank 3, and a water inlet 15 is fixedly connected to the top of the first tank 3. A water storage tank 18 is fixedly connected inside the water inlet 15.

[0031] Multiple nozzles 19 are fixedly connected to the bottom of the water storage tank 18, and a connecting pipe 16 is fixedly connected to the outside of the water storage tank 18.

[0032] Specifically: water from the external water pipe enters the water storage tank 18 inside the outlet 15 through the connecting pipe 16, and is sprayed out through the nozzle 19 at the bottom, thus entering the first tank 3.

[0033] Multiple suction cups 5 are provided on the outside of the can lid 4, and a fixing plate 6 is fixedly connected to the outside of the suction cups 5.

[0034] A vent pipe 7 is fixedly connected inside the fixed plate 6, and a second tank 8 is fixedly connected to one end of the vent pipe 7.

[0035] The top of the second tank 8 is fixedly connected to a port 9, and an observation window 10 is opened inside the second tank 8.

[0036] Specifically: Connect the vent pipe 7 and the fixing plate 6 fixed at one end to the can lid 4 with the suction cup 5. Insert the vent pipe 7 into the first can 3. Then pour water into the second can 8 through the port 9. Insert one end of the vent pipe 7 into the second can 8 so that one end of the vent pipe 7 contacts the water inside the second can 8. Observe through the observation window 10. If there is no reaction in the water inside the second can 8, it means that the first can 3 is airtight. Conversely, if bubbles are generated, it means that the first can 3 is leaking.

[0037] Working Principle: Before deoxygenating the water, check the airtightness of the first tank 3. Connect the vent pipe 7 and the fixing plate 6 fixed at one end to the tank cover 4 with the help of the suction cup 5. Insert the vent pipe 7 into the first tank 3. Then pour water into the second tank 8 through the port 9. Insert one end of the vent pipe 7 into the second tank 8 so that one end of the vent pipe 7 is in contact with the water inside the second tank 8. Observe through the observation window 10. If there is no reaction in the water inside the second tank 8, it means that the first tank 3 is airtight. Conversely, if bubbles are generated, it means that the first tank 3 has an air leak and needs to be repaired by the operator. This ensures that all components of the deaerator work under normal pressure and temperature conditions, avoids damage or failure of equipment components due to pressure fluctuations, leakage and other problems, ensures the stable operation of the deaerator and the entire thermal system, reduces the number of downtimes caused by equipment failure, and improves production efficiency. Then, connect the external water pipe to the connecting pipe 16. The water in the external water pipe enters the outlet 1 through the connecting pipe 16. The water is stored in the water tank 18 inside the first tank 3 and sprayed out through the nozzle 19 at the bottom, thus entering the first tank 3. Then, the first motor 11 is started. Driven by the first motor 11 and the first drive rod 12, the heating rod 13 inside the first tank 3 is rotated. At the same time, the heating rod 13 heats the water to generate steam, removing oxygen from the water. Then, it is discharged through the water outlet pipe 17 at the bottom. During the discharge process, impurities may adhere to the inside of the water outlet pipe 17. At this time, the impact force generated by the water discharge causes the internal rotating shaft 23 to rotate, thereby driving the blade 24 outside the rotating shaft 23 to rotate and crush the impurities in the water. Then, driven by the second motor 28 and the second drive rod 27, the limiting block 26 inside the fixed block 25 moves out of the groove inside the fixed block 25 to discharge the water. This ensures that the deoxygenated water can be smoothly delivered to the subsequent system and maintain the normal operation of the thermal deaerator and the entire thermal system.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
