Description

Technical Field

[0001] This utility model relates to the field of incinerator boiler technology, specifically to a cooling device for a feedwater pump in an incinerator boiler. Background Technology

[0002] An incinerator is an environmentally friendly device that uses high-temperature combustion to reduce or minimize the amount of waste gas, waste liquid, solid waste, fuel, medical waste, household waste, animal carcasses, etc. It can also utilize some of the heat energy of the incinerating medium. An incinerator boiler usually refers to a waste heat boiler used in conjunction with an incinerator. It is mainly used to recover the heat from the high-temperature flue gas generated during the incineration process and convert it into hot water or steam to achieve energy recovery and utilization. The feedwater pump is a key device that provides qualified feedwater to the waste heat boiler connected to the incinerator. Its function is to pressurize the treated water (such as softened water or demineralized water) and deliver it to the economizer or steam drum of the boiler to ensure the normal water circulation and steam production of the boiler.

[0003] Currently, boiler feedwater pumps lack auxiliary cooling mechanisms. Due to mechanical friction within the pump body and the continuous operation of the motor, a large amount of heat is generated, causing the pump body and motor temperatures to rise. Since incinerator boiler feedwater pumps typically operate in harsh environments with relatively high ambient temperatures, failure to effectively cool them in a timely manner can affect their normal operation, reduce their efficiency, and even shorten their lifespan. In severe cases, it may even lead to equipment failure and affect the stable operation of the incinerator boiler system. Therefore, a cooling device for incinerator boiler feedwater pumps is proposed to add an auxiliary cooling mechanism. Utilizing diversion and heat exchange methods, the pump body casing is cooled and vented simultaneously with pump operation, improving operational stability and thus enhancing performance. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a cooling device for a boiler feedwater pump in an incinerator, which utilizes diversion and heat exchange to provide auxiliary heat dissipation and cooling for the pump body casing, thereby improving the performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a cooling device for a feed water pump of an incinerator boiler, including a feed water pump, a motor and a cooling component. The cooling component is fixedly sleeved on the periphery of the feed water pump, and the feed water pump includes a shell.

[0006] The cooling component includes a sleeve, which is fixedly connected to a water pump by bolts. An annular heat-conducting plate is welded inside the sleeve. A hollow groove is formed around the annular heat-conducting plate inside the sleeve. A spiral blade is arranged inside the hollow groove and welded to the annular heat-conducting plate.

[0007] By adopting the above technical solution, a passive cooling structure is formed by using diversion, flow guidance and heat exchange methods to perform auxiliary heat dissipation and cooling treatment on the shell.

[0008] Specifically, a rotating shaft is provided on one side of the housing, and a bearing corresponding to the rotating shaft is provided on one side inside the housing. A heat dissipation channel is provided on the side of the bearing inside the housing, and a partition is bolted between the heat dissipation channel and the bearing.

[0009] Specifically, a diversion pipe is provided on one side of the top of the sleeve, and a return pipe is provided on the other side of the top of the sleeve.

[0010] Specifically, a heat-conducting plate is provided inside the heat dissipation channel, a heat-conducting plate is welded to the inner side of the heat dissipation channel, and a ball bearing is rolled on the surface of the heat-conducting plate through a reserved ball groove.

[0011] Specifically, the top of the housing has an inlet, and the bottom of the housing has an outlet, both of which are connected to a heat dissipation channel.

[0012] Specifically, the water pump has an inlet on one side of its top and an outlet on the other side of its top, and the outlet end of the return water pipe is connected to the outlet.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To facilitate the use of flow diversion and heat exchange, auxiliary heat dissipation and cooling treatment is applied to the pump body casing to improve its performance. Figure 1-3 As shown, the present invention provides a cooling device for a boiler feedwater pump, which includes a feedwater pump 1, a motor 2, and a cooling component 3. The cooling component 3 is fixedly sleeved around the feedwater pump 1, and the feedwater pump 1 includes a housing 5.

[0025] The cooling component 3 includes a sleeve 301, and the sleeve 301 is fixedly connected to the water pump 1 by bolts. An annular heat-conducting plate 302 is welded inside the sleeve 301. A hollow groove 303 is opened in the sleeve 301 around the annular heat-conducting plate 302. A spiral blade 304 is provided in the hollow groove 303, and the spiral blade 304 is welded to the annular heat-conducting plate 302.

[0026] In use, an auxiliary cooling mechanism is added through sleeve 301, annular heat-conducting plate 302, hollow groove 303 and spiral blade 304. By using the methods of diversion, flow guidance and heat exchange, a passive cooling structure is formed. While the water pump is working, auxiliary heat dissipation and cooling treatment is carried out to improve the stability of the water pump in harsh working environments.

[0027] The annular heat-conducting plate 302, the spiral blade 304, the partition 503, the heat-conducting sheet 504, the heat-conducting plate 505, and the ball bearing 506 are all made of copper.

[0028] For example, such as Figure 3 , Figure 4 As shown, the present invention also includes a rotating shaft 6 on one side of the housing 5, a bearing 501 corresponding to the rotating shaft 6 on one side inside the housing 5, a heat dissipation channel 502 on one side of the bearing 501 inside the housing 5, and a partition plate 503 connected between the heat dissipation channel 502 and the bearing 501 by bolts.

[0029] During use, an active cooling mechanism is added by rotating shaft 6, bearing 501, heat dissipation channel 502 and partition 503. The bearing 501 and rotating shaft 6 are actively cooled by pumping in cooling medium from the outside, which further improves the stability of the water pump 1.

[0030] For example, such as Figure 2 As shown, the present invention also includes a diversion pipe 305 provided on one side of the top of the sleeve 301, and a return pipe 306 provided on the other side of the top of the sleeve 301.

[0031] In use, the diversion pipe 305 and the return water pipe 306 facilitate the flow of water in and out of the sleeve 301, achieving a passive cooling effect. The return water pipe 306 includes a one-way valve.

[0032] For example, such as Figure 4 As shown, the present invention also includes a heat-conducting sheet 504 disposed inside the heat dissipation channel 502, a heat-conducting plate 505 welded to the inner side of the heat dissipation channel 502, and a ball bearing 506 rolledly connected to the surface of the heat-conducting plate 505 through a reserved ball groove.

[0033] During use, the heat-conducting sheet 504, heat-conducting plate 505, and ball bearings 506 enable the cooling medium to fully absorb heat and carry it away. At the same time, the rolling contact improves the cooling effect on the rotating shaft 6.

[0034] For example, such as Figure 4 As shown, the present invention also includes an inlet 507 at the top of the housing 5 and an outlet 508 at the bottom of the housing 5, and both the inlet 507 and the outlet 508 are connected to the heat dissipation channel 502.

[0035] During use, the medium in the heat dissipation channel 502 is facilitated by the inlet 507 and outlet 508 for active cooling.

[0036] For example, such as Figure 1 , 3As shown, the present invention also includes an inlet 101 on one side of the top of the water pump 1, an outlet 102 on the other side of the top of the water pump 1, and the outlet end of the return water pipe 306 is connected to the outlet 102. A diversion valve 4 is provided on the top of the water pump 1, and the outlet end of the diversion valve 4 is connected to the diversion pipe 305 and the inlet 101.

[0037] During use, the water inlet 101 and outlet 102 facilitate the entry and exit of water into the water supply pump 1, and the diversion valve 4 facilitates the diversion of the inlet water to passively cool the water supply pump 1.

[0038] For example, such as Figure 1 As shown, the present invention also includes a motor 2 provided on one side of the water pump 1, and a coupling 7 provided between the motor 2 and the rotating shaft 6.

[0039] In use, the motor 2 and coupling 7 facilitate the rotation of the rotating shaft 6 to drive the water pump 1 to work.

[0040] In use, water enters the water pump 1 through the diversion valve 4 and the inlet 101 connected by the pipeline. Part of the water enters the hollow groove 303 of the sleeve 301 through the diversion valve 4 and the diversion pipe 305. By using the contact between the annular heat-conducting plate 302 and the housing 5 of the water pump 1, the heat generated on its surface can be absorbed and transferred to the spiral blades 304. Then, through the contact between the diverted water and the spiral blades 304, the heat is carried away from the sleeve 301 and enters the outlet 102 through the return water pipe 306 to complete the return water supply. This achieves passive heat dissipation and cooling treatment during the operation of the water pump 1, so as to improve the working environment of the water pump 1 and improve the continuity and stability of use.

[0041] While the water pump 1 is working, the cooling fan can also be turned on. The airflow blown out by the cooling fan is sent into the spiral groove composed of heat-conducting plates 504 in the heat dissipation channel 502 through the pre-connected pipe. By blowing air to cool, the heat absorbed by the partition plate 503, heat-conducting plates 504, and heat-conducting plate 505 is discharged from the rotating shaft 6 and bearing 501, which achieves the effect of active heat dissipation and cooling. This will further improve the stability of the water pump 1 and help extend its actual service life.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
