Description

Technical Field

[0001] The present disclosure relates to the technical field of combustion-supporting fans for hot blast stoves, and in particular to a bearing package system for a combustion-supporting fan. Background Art

[0002] In daily production, the combustion-supporting fan for a blast furnace hot blast stove provides cooling air and combustion-supporting air to the preheating furnace. The high-speed fan rotor is supported at both ends by bearings, which are located in a bearing package. A cooling chamber within the bearing package circulates cooling water to cool the high-speed bearings. Because the combustion-supporting fan often operates 24 hours a day, cooling water also needs to be supplied 24 hours a day to ensure the cooling of the bearing package. Long-term operation can cause scale to accumulate in the bearing package cooling chamber, affecting the cooling effect of the bearing. Severe scale accumulation can narrow or even block the cooling water channel, affecting the cooling effect of the cooling water on the bearing and causing bearing burns. Summary of the Invention

[0063] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0064] like Figure 1 As shown, according to an embodiment of the present disclosure, a combustion-supporting fan bearing package 310 system is proposed, including: a liquid supply station 100 for providing cooling liquid; a liquid return station 200 for recovering cooling liquid; a bearing package 310 component 300, having a first interface 3001 and a second interface 3002, the first interface 3001 is connected to the liquid supply station 100, and the second interface 3002 is connected to the liquid return station 200; a cleaning component 400, having a cleaning end and a discharge end, the cleaning end is used to output cleaning liquid, and the discharge end is used to discharge cleaning liquid, the cleaning end is connected to the second interface 3002, and the discharge end is connected to the first interface 3001.

[0065] The combustion-supporting fan bearing package 310 system proposed in accordance with an embodiment of the present disclosure includes a liquid supply station 100, a liquid return station 200, a bearing package 310 assembly 300 and a cleaning assembly 400, wherein the liquid supply station 100 is connected to the first interface 3001 of the bearing package 310 assembly 300, and the liquid return station 200 is connected to the second interface 3002 of the bearing package 310 assembly 300. During the cooling process of the cooling liquid, the liquid supply station 100 outputs the cooling liquid, and the cooling liquid enters the bearing package 310 assembly 300 from the first interface 3001 to cool the bearing inside the bearing package 310. The cooling liquid then flows out from the second interface 3002 and flows into the liquid return station 200 for recovery; the cleaning end of the cleaning component 400 is connected to the second interface 3002, and the discharge end of the cleaning component 400 is connected to the first interface 3001. In the process of cleaning the bearing package 310 with the cleaning liquid, the cleaning end outputs the cleaning liquid, and the cleaning liquid can enter the bearing package 310 component 300 from the second interface 3002 and then be discharged from the first interface 3001; the flow direction of the cleaning liquid and the cooling liquid can be opposite, which is beneficial for the cleaning liquid to remove impurities accumulated in the cooling liquid inside the bearing package 310.

[0066] It should be noted that during the cooling cycle of the cooling liquid, impurities such as hardened deposits will form at the corners and bottom of the flow channel of the bearing package cooling cavity. The cleaning liquid will have a strong impact on these impurities through the flow direction completely opposite to that of the cooling liquid, forming a hedging effect, so that the cleaning liquid can more deeply and efficiently remove the impurities accumulated by the cooling liquid inside the bearing package 310, significantly improving the cleaning and maintenance effect of the bearing package 310 system, and ensuring the stable and efficient operation of the combustion-supporting blower.

[0067] It is understandable that the cooling liquid may be cooling water or industrial lubricating oil.

[0068] It is understandable that adding chemical reagents to the cleaning fluid can better dissolve the hardened deposits.

[0069] It is understandable that the cooling liquid recovered by the liquid return station 200 can be injected into the liquid supply station 100 for use after treatment, or can be directly discharged, and no further restrictions are imposed here.

[0070] For example, the cleaning liquid can be a liquid with a cooling effect, so that the cleaning liquid can not only clean the bearing package 310, but also temporarily cool the bearing package 310 instead of the cooling liquid. During the cleaning process, the combustion-supporting fan can continue to operate, which is conducive to ensuring the stable and efficient operation of the combustion-supporting fan.

[0071] In some examples, such as Figure 1As shown, the cleaning component 400 includes: a mixing section 410 for storing cleaning liquid, the mixing section 410 having a liquid inlet and a liquid discharge port; a cleaning section 420, the cleaning end is formed at one end of the cleaning section 420, and the other end of the cleaning section 420 is connected to the liquid discharge port; a recovery section 430, the discharge end is formed at one end of the recovery section 430, and the other end of the recovery section 430 is connected to the liquid inlet; a filter section 440 is arranged in the mixing section 410, and the filter section 440 is located between the liquid inlet and the liquid discharge port.

[0072] In the above technical solution, the cleaning component 400 includes a mixing part 410, a cleaning part 420, a recovery part 430 and a filtering part 440, wherein the cleaning liquid is stored in the mixing part 410, and the mixing part 410 has a liquid inlet and a liquid discharge port; the liquid discharge port is connected to the cleaning part 420, and the cleaning part 420 is used to transport the cleaning liquid, and the liquid inlet of the mixing part 410 is connected to the recovery part 430, and the recovery part 430 is used to transport the cleaning liquid after cleaning and the impurities flushed out from the bearing package 310 component 300; in actual application, the cleaning liquid can flow from the liquid discharge port of the mixing part 410 into the cleaning part 420, and then flow into the cleaning end of the cleaning part 420 through the cleaning end The second interface 3002 is used to clean the bearing package 310 assembly 300; the cleaning liquid after cleaning and the impurities inside the bearing package 310 assembly 300 carried by it enter the recovery section 430 from the first interface 3001 and the recovery end, and the recovery section 430 can transport the impurities in the cleaning liquid back to the mixing section 410, thereby realizing the recovery of the cleaning liquid; at the same time, since the mixing section 410 is provided with a filter section 440 between the liquid inlet and the liquid outlet, the impurities transported to the mixing section 410 by the recovery section 430 will be intercepted by the filter section 440 in the process of flowing from the liquid inlet to the liquid outlet, and the cleaning liquid can flow from the liquid inlet to the liquid outlet, thereby realizing the recycling of the cleaning liquid.

[0073] Exemplarily, the recovery part 430 includes a recovery pipeline and a control valve, and the control valve is used to control the opening of the recovery pipeline; one end of the recovery pipeline is the recovery end, and the other end is connected to the liquid inlet.

[0074] Exemplarily, the recovery line adopts a quick-connect metal hose.

[0075] In some examples, such as Figure 1 As shown, the mixing section 410 includes: a mixing pool 411, wherein the liquid inlet and the liquid discharge port are both formed in the mixing pool 411, the liquid discharge port is spaced apart from the bottom wall of the mixing pool 411, and the liquid inlet is located at the pool mouth of the mixing pool 411; a float 412, which is movably inserted into the mixing pool 411 and is used to detect the content of the cleaning liquid in the mixing pool 411.

[0076] In the above technical solution, the mixing section 410 includes a mixing tank 411 and a float 412. The mixing tank 411 is used to store cleaning liquid, and the cleaning liquid can be prepared and mixed in the mixing tank 411; the mixing tank 411 has the above-mentioned liquid inlet and discharge port, wherein the discharge port is located on the side wall of the mixing tank 411, and there is a gap between the discharge port and the bottom wall of the mixing tank 411, which can improve the purity of the cleaning liquid and reduce the probability of impurities being discharged from the discharge port; it can be understood that after a small amount of impurities enter the mixing tank 411, they will be deposited on the bottom wall of the mixing tank 411, and due to the height difference between the discharge port and the bottom wall, the impurities can be blocked from entering the discharge port; the float 412 is movably inserted in the mixing tank 411, more specifically, the float 412 is movably inserted in the cleaning liquid in the mixing tank 411, and the setting of the float 412 can make it easier for the operator to judge the content of the cleaning liquid inside the mixing tank 411, so that the operator can add it according to actual conditions.

[0077] It is understandable that the recovery part 430 can be arranged directly above the liquid inlet of the mixing tank 411, so that the cleaning liquid and impurities discharged from the recovery part 430 can directly fall into the mixing tank 411 under the action of gravity.

[0078] For example, the mixing tank 411 is fixed on a movable cart, and universal wheels and brake devices are installed at the four corners below the bottom plate of the cart to realize the movement and fixation of the solution mixing tank 411.

[0079] In some examples, such as Figure 1 As shown, the mixing portion 410 further includes: a first valve body 413; the mixing tank 411 is formed with an emptying port, and the first valve body 413 is arranged at the emptying port; wherein the position height of the emptying port is lower than the position height of the liquid discharge port.

[0080] In the above technical solution, the mixing section 410 also includes a first valve body 413, which is arranged at the drain port of the mixing tank 411. The first valve body 413 is used for the opening of the drain port. The position height of the drain port is lower than the position height of the drain port. When the cleaning liquid in the mixing tank 411 needs to be replaced or the mixing tank 411 needs to be cleaned, the drain port can be opened by controlling the first valve body 413 to allow the cleaning liquid and a small amount of impurities in the mixing tank 411 to be discharged from the drain port.

[0081] It is understandable that when a certain amount of impurities are deposited on the bottom wall of the mixing tank 411, the drain port can also be opened to allow the impurities to be discharged from the drain port to prevent the impurities from entering the cleaning cycle from the drain port.

[0082] Exemplarily, the drain port is provided on the bottom wall of the mixing tank 411 , or the drain port is close to the bottom wall of the mixing tank 411 and is opened on the side wall of the mixing tank 411 .

[0083] In some examples, such as Figure 1 As shown, the cleaning portion 420 includes: a cleaning pipeline 421, a cleaning end is formed at one end of the cleaning pipeline 421, and the other end of the cleaning pipeline 421 is connected to the discharge port; a pump body 422, arranged in the cleaning pipeline 421; a filter 423, arranged in the cleaning pipeline 421, located between the pump body 422 and the cleaning end; a second valve body 424, arranged in the cleaning pipeline 421, located between the filter 423 and the cleaning end.

[0084] In the above technical solution, the cleaning section 420 includes a cleaning pipeline 421, a pump body 422, a filter 423 and a second valve body 424, wherein the cleaning pipeline 421 is used to establish a delivery channel, the second valve body 424 is used to control the opening of the cleaning pipeline 421, and the pump body 422 is connected to the cleaning pipeline 421 to increase the flow rate and flow pressure of the cleaning liquid, so that the cleaning liquid delivered by the cleaning section 420 to the bearing package 310 component 300 has a certain impact force, which is beneficial to improving the cleaning effect. A filter 423 is also provided between the pump body 422 and the cleaning end. The filter 423 can filter the cleaning liquid, thereby preventing impurities inside the mixing tank 411 from entering the bearing package 310 component 300 through the cleaning pipeline 421.

[0085] It should be noted that during the flushing process, close attention should be paid to the position of the float 412 in the mixing tank 411 and the scale filtered out above the filter part 440 to prevent the filter layer from being blocked by excessive scale and the solution from not being able to reach the lower part of the mixing tank 411, causing the pump body 422 to be sucked empty.

[0086] In some examples, such as Figure 1 As shown, the cleaning unit 420 further includes:

[0087] A three-way connector is provided on the cleaning pipeline 421. The three-way connector has a first connection port, a second connection port, and a third connection port. The first connection port is connected to the pump body 422, and the second connection port is connected to the filter 423.

[0088] A sewage discharge pipeline is connected to the third connection port;

[0089] The third valve body 425 is provided in the sewage discharge pipeline;

[0090] The second connection port and the third connection port are both connected along the direction of the sewage pipe pointing to the filter 423, and the position height of the second connection port is higher than the position height of the third connection port.

[0091] In the above technical solution, the cleaning part 420 also includes a three-way joint, which is arranged between the pump body 422 and the filter 423. The three-way joint is also connected to the sewage pipe. In the absence of cleaning, the water inside the cleaning pipe 421 can be drained through the sewage pipe to prevent the pipe from freezing and cracking in the cold winter.

[0092] It can be understood that the second connection port and the third connection port are both connected in the direction of the sewage pipe pointing to the filter 423, and the position height of the second connection port is higher than the position height of the third connection port. In this way, the filter 423 can intercept impurities and some impurities can fall into the sewage pipe under the action of gravity and then be discharged from the sewage pipe; in some examples, such as Figure 1 As shown, the filter portion 440 includes: at least two filter elements 441, which are detachably disposed on the mixing portion 410, and are arranged at intervals along the direction from the liquid inlet to the liquid outlet.

[0093] In the above technical solution, the filter part 440 includes at least two filter elements 441, and at least two filter elements 441 are arranged at intervals along the direction from the liquid inlet to the liquid outlet, which can realize multi-stage filtration and is beneficial to improving the filtering effect; at the same time, at least two filter elements 441 are detachably arranged in the mixing tank 411, which is convenient for replacing and cleaning the filter elements 441.

[0094] It is understandable that at least two filter elements 441 may use filter screens of different precisions, thereby achieving graded filtration of impurities and improving the filtering effect, while also helping to prevent impurities from clogging the filter screens.

[0095] In some examples, such as Figure 1 As shown, the bearing package 310 assembly 300 includes: two bearing packages 310, each bearing package 310 is formed with a first interface 3001 and a second interface 3002; a liquid supply part 320, each first interface 3001 is connected to one end of the liquid supply part 320, and the other end of the liquid supply part 320 is connected to the liquid supply station 100; a liquid return part 330, each second interface 3002 is connected to one end of the liquid return part 330, and the other end of the liquid return part 330 is connected to the liquid return station 200.

[0096] In the above technical solution, the bearing package 310 assembly 300 includes two bearing packages 310, and the two bearing packages 310 correspond to the support end bearing and the thrust end bearing respectively; a first interface 3001 and a second interface 3002 are formed at both ends of each bearing package 310, so that each bearing package 310 is located in the cooling cycle of the cooling liquid and the cleaning cycle of the cleaning liquid; the liquid supply part 320 is connected to the liquid supply station 100 and the first interface 3001, and the liquid return part 330 is connected to the liquid return station 200 and the second interface 3002; the liquid supply station 100 can transport cooling liquid to the two bearing packages 310 through the liquid supply station 100; the cooling liquid cools the inside of the bearing package 310 and then flows out from the second interface 3002, and flows into the liquid return station 200 for recovery through the liquid return part 330.

[0097] In a feasible embodiment, a sixth valve body is further provided between the first interface and the liquid supply part 320, and a sixth valve body is also provided between the second interface and the liquid return part 330. The sixth valve body can be used to control the opening of the pipeline, thereby controlling the speed of the cooling cycle; the bearing package can also be switched from the original cooling system to the cleaning system by closing the sixth valve body.

[0098] In some examples, such as Figure 1 As shown, the liquid supply part 320 includes: a liquid supply pipeline 321, the number of which is at least two, each first interface 3001 is connected to one end of at least two liquid supply pipelines 321, and the other end of the liquid supply pipeline 321 is connected to the liquid supply station 100; a one-way valve 322, each liquid supply pipeline 321 is provided with a one-way valve 322; a fourth valve body 323, arranged on the liquid supply pipeline 321, and at least one fourth valve body 323 is provided on both sides of each one-way valve 322; a pressure detector 324, each liquid supply pipeline 321 is provided with at least one pressure detector 324.

[0099] In the above technical solution, the liquid supply part 320 includes a liquid supply pipeline 321, a one-way valve 322, a fourth valve body 323 and a pressure detector 324. Each first interface 3001 is connected to at least two liquid supply pipelines 321, so that even if one of the liquid supply pipelines 321 fails, the other liquid supply pipeline 321 can continue to be used, which is conducive to ensuring the continuous use of the combustion-supporting fan; the liquid supply pipeline 321 is also provided with a one-way valve 322, which is conducted along the liquid supply station 100 toward the bearing package 310 to avoid backflow of the cooling liquid. The fourth valve body 323 is provided at both ends of the one-way valve 322. The fourth valve body 323 is used to control the opening of the liquid supply pipeline 321, so that when installing or removing the one-way valve 322, the two ends of the one-way valve 322 can be cut off to ensure that the one-way valve 322 is in a pressure-free state in the pipeline. A pressure detector 324 is also provided on the liquid supply pipeline 321 to facilitate operators to detect the pressure in the liquid supply pipeline 321 .

[0100] It is understandable that in actual applications, the liquid supply station 100 is often not in the same plant area as the combustion-supporting fan. Therefore, at least one pressure detector 324 is often set in the plant area where the combustion-supporting fan is located, and a pressure detector 324 is set in the plant area where the liquid supply station 100 is located. This is beneficial for operators to judge the status of the liquid supply pipeline 321 based on the difference in pressure information detected by the pressure detectors 324 in the two plant areas.

[0101] Exemplarily, the bearing package 310 assembly 300 also includes a backup pipeline 325, one end of which is connected to the first interface 3001, and the other end uses a quick-connect valve 326. In the event of a failure in the liquid supply pipeline 321, the backup pipeline 325 can be temporarily used to inject cooling liquid into the bearing package 310.

[0102] In some examples, such as Figure 1 As shown, the liquid return portion 330 includes: a liquid return pipeline 331, each second interface 3002 is connected to one end of the liquid return pipeline 331, and the other end of the liquid return pipeline 331 is connected to the liquid return station 200; a quick exhaust pipeline 332, one end of the quick exhaust pipeline 332 is connected to the second interface 3002, and the other end is used to connect to the waste liquid discharge area; a fifth valve body 333, which is arranged on the quick exhaust pipeline 332.

[0103] In the above technical solution, the liquid return section 330 includes a liquid return line 331. Each second interface 3002 is connected to the liquid return line 331 and to the liquid return station 200. The second interface 3002 is also connected to a quick-exhaust line 332. In the event of a failure in the liquid return line 331, the cooling liquid within the bearing package 310 can be discharged through the quick-exhaust line 332.
