Description

Technical Field

[0001] The invention relates to the field of sintering ring cooling, and in particular to an easy-to-clean sealed water tank of a ring cooling device and a method for using the same. Background Art

[0002] Sintering ring cooling is a key link in the iron ore sintering process. It is mainly used to quickly cool the ore that has been sintered at high temperature to ensure that the physical and chemical properties of the ore meet the requirements of subsequent processing. There is a lot of smoke and dust in the sintering ring cooling equipment, so the sintering ring cooling equipment needs to be sealed to prevent the smoke and dust in the equipment from overflowing and affecting the surrounding environment.

[0003] At present, water sealing equipment is usually used to seal the sintering ring cooling trolley. However, some of the dust in the ring cooling equipment will enter the sealed water tank and gradually settle in the water tank to form sludge. Too much sludge will cause the amount of water in the sealed water tank to decrease. Since the working temperature of the sintering ring cooling is relatively high, about 500-700℃, the reduction of water in the sealed water tank will easily cause all the water in the water tank to evaporate, and the sealing effect cannot be achieved.

[0004] Cleaning the sealed water tank also needs to be done during the production stoppage. First, all the water in the sealed water tank needs to be drained, and then the sludge at the bottom of the water tank needs to be manually removed, which is very inconvenient. Summary of the invention

[0005] The purpose of the present invention is to provide an easy-to-clean sealed water tank of an annular cooling device and a method for using the same. The easy-to-clean sealed water tank of the annular cooling device can clean the sludge in the sealed water tank to a cleaning pipe in time by arranging a scraper, and the sludge in the cleaning pipe can also be conveniently discharged.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a sealed water tank of an annular cooling device that is easy to clean, the sealed water tank of the annular cooling device that is easy to clean comprises an annular cooling trolley, a top sealing cover and a cleaning pipe, a sealed water tank is arranged on the outer periphery of the top of the annular cooling trolley, the sealed water tank cooperates with the top sealing cover, the top sealing cover cooperates with the sealed water tank to achieve sealing of the annular cooling trolley, a scraper that cooperates with the sealed water tank is arranged at the lower end of the top sealing cover, the bottom of the sealed water tank is connected with the cleaning pipe, and the cleaning pipe is provided with a first valve;

[0007] The sealed water tank comprises a water inlet pipe, on which a second valve is arranged, and the second valve controls the water inlet pipe to inject water into the sealed water tank.

[0008] Preferably, the sealed water tank further comprises a sensor, wherein the sensor is used to detect the water level in the sealed water tank, and the sensor is electrically connected to the second valve.

[0009] Preferably, a first sealing ring and a second sealing ring are coaxially extended downwardly from the lower end of the sealing cover, the first sealing ring is located in the cooling trolley, and the second sealing ring is at least partially immersed in the water of the sealing water tank in the height direction;

[0010] The scraper is arranged at the lower end of the second sealing ring.

[0011] The present invention also provides a method for sealing a water tank using the easy-to-clean annular cooling device, the method comprising:

[0012] Step 1, close the first valve, open the second valve, and inject water into the sealed water tank through the water inlet pipe;

[0013] Step 2: As the cooling trolley rotates, the scraper drives the sludge in the sealed water tank to the inlet of the cleaning pipe;

[0014] Step 3, opening the first valve to discharge the sludge in the sewage cleaning pipe;

[0015] Step 4: Close the first valve.

[0016] Preferably, in step 3, when the first valve is opened, water needs to be injected into the sealed water tank.

[0017] Preferably, the first valve is electrically connected to the second valve, and the first valve controls the second valve to open.

[0018] Preferably, in step 3, whether the sludge is completely discharged is determined by observing the height of the sludge in the cleaning pipe.

[0019] Preferably, in step one, the sensor is electrically connected to the second valve, and the sensor controls the water inlet pipe to automatically inject water into the sealed water tank.

[0020] According to the above technical solution, the sealing cover of the present invention is arranged on the top of the cold ring trolley for sealing the cold ring trolley. In the actual production process, the cold ring trolley will rotate continuously, and the sealing cover is coaxially arranged with the cold ring trolley. The sealing cover is stationary during the rotation of the cold ring trolley. A sealing water tank is arranged on the outer periphery of the cold ring trolley. A certain amount of water is injected into the sealing water tank. The outer ring of the sealing cover is immersed in the sealing water tank, which can realize the water sealing of the cold ring trolley, so that the smoke in the cold ring trolley cannot escape to the outside, thereby protecting the surrounding environment.

[0021] As production continues, the water in the sealing water tank will gradually evaporate. Therefore, in order to achieve a reliable sealing effect on the cold ring trolley, it is necessary to set up a water inlet pipe to replenish water in the sealing water tank to avoid sealing failure due to water evaporation during the production process.

[0022] Preferably, a second valve is provided on the sealed water tank, and effective water replenishment of the sealed water tank can be achieved by controlling the opening or closing of the second valve, thereby avoiding the waste of water resources caused by continuous water replenishment.

[0023] A scraper is fixed under the sealing cover and extends into the sealing water tank. During the production process, the sealing water tank will rotate with the cold ring trolley, while the scraper in the sealing water tank remains stationary. Therefore, during the rotation of the sealing water tank, there is relative movement between the scraper and the sealing water tank, so that the scraper can push the sludge at the bottom of the sealing water tank until the sludge is pushed to the position of the cleaning pipe. The sludge will flow down along the cleaning pipe and eventually accumulate above the first valve.

[0024] When the sealed water tank needs to be discharged, it is only necessary to open the first valve, and the sludge accumulated in the sewage cleaning pipe can be directly discharged. After all the sludge is discharged, the first valve can be closed.

[0025] Therefore, the sealed water tank of the ring cooling equipment that is easy to clean can reliably clean the sludge generated during the production process and deposited at the bottom of the sealed water tank by setting a scraper, so that there is always enough water in the sealed water tank for sealing the cooling ring trolley. The sludge cleaned by the scraper is stored in the cleaning pipe, which has a certain capacity and can store the sludge generated during the production process until the sludge needs to be discharged. The sludge cleaning work of the sealed water tank can be realized by opening the first valve, so it is very convenient. Moreover, there is no need to stop production at all, and the sealed water tank can be cleaned online.

[0026] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0039] See also Figure 1 A sealed water tank of an annular cooling device that is easy to clean, the sealed water tank of the annular cooling device that is easy to clean comprises an annular cooling trolley 1, a top sealing cover 2 and a cleaning pipe 4, a sealed water tank 3 is arranged on the outer periphery of the top of the annular cooling trolley 1, the sealed water tank 3 cooperates with the top sealing cover 2, the top sealing cover 2 cooperates with the sealed water tank 3 to achieve sealing of the annular cooling trolley 1, a scraper 6 that cooperates with the sealed water tank 3 is arranged at the lower end of the top sealing cover 2, the bottom of the sealed water tank 3 is connected with the cleaning pipe 4, and the cleaning pipe 4 is provided with a first valve 5;

[0040] The sealed water tank 3 comprises a water inlet pipe, on which a second valve is arranged, and the second valve controls the water inlet pipe to inject water into the sealed water tank 3 .

[0041] Through the implementation of the above technical solution, the sealing cover 2 is covered on the top of the cold ring trolley 1 to seal the cold ring trolley 1. In the actual production process, the cold ring trolley 1 will rotate continuously, and the sealing cover 2 is coaxially arranged with the cold ring trolley 1. The sealing cover 2 is stationary during the rotation of the cold ring trolley 1. A sealing water tank 3 is arranged on the outer periphery of the cold ring trolley 1. A certain amount of water is injected into the sealing water tank 3. The outer ring of the sealing cover 2 is immersed in the sealing water tank 3, which can realize the water sealing of the cold ring trolley 1, so that the smoke in the cold ring trolley 1 cannot escape to the outside, thereby protecting the surrounding environment.

[0042] As production continues, the water in the sealing water tank 3 will gradually evaporate. Therefore, in order to achieve a reliable sealing effect on the cold ring trolley 1, it is necessary to set a water inlet pipe to replenish the sealing water tank 3 to avoid sealing failure due to water evaporation during the production process.

[0043] Preferably, a second valve is provided on the sealed water tank 3, and effective water replenishment of the sealed water tank 3 can be achieved by controlling the opening or closing of the second valve, thereby avoiding the waste of water resources caused by continuous water replenishment.

[0044] A scraper 6 is fixed under the sealing cover 2, and the scraper 6 extends into the sealed water tank 3. During the production process, the sealed water tank 3 will rotate with the cold ring trolley 1, while the scraper 6 located in the sealed water tank 3 remains stationary. Therefore, during the rotation of the sealed water tank 3, there is a relative movement between the scraper 6 and the sealed water tank 3, so that the scraper 6 can push the sludge at the bottom of the sealed water tank 3 until the sludge is pushed to the position of the cleaning pipe 4. The sludge will flow down along the cleaning pipe 4 and eventually accumulate above the first valve 5.

[0045] When it is necessary to discharge sewage from the sealed water tank 3, it is only necessary to open the first valve 5, and the sludge accumulated in the sewage cleaning pipe 4 can be directly discharged. After the sludge 11 is completely discharged, the first valve 5 can be closed.

[0046] Therefore, the sealed water tank of the ring cooling equipment that is easy to clean can realize reliable cleaning of the sludge 11 generated during the production process and deposited at the bottom of the sealed water tank 3 by setting the scraper 6, so that the sealed water tank 3 can always retain a sufficient amount of water for sealing the cooling ring trolley 1. The sludge 11 cleaned by the scraper 6 is stored in the cleaning pipe 4, which has a certain capacity and can store the sludge 11 generated during the production process until the sludge 11 needs to be discharged. The cleaning work of the sludge 11 in the sealed water tank 3 can be realized by opening the first valve 5, so it is very convenient. Moreover, there is no need to stop production at all, and the sealed water tank 3 can be cleaned online.

[0047] In this embodiment, preferably, the sealed water tank 3 further includes a sensor, and the sensor is used to detect the water level in the sealed water tank 3, and the sensor is electrically connected to the second valve.

[0048] By providing the sensor, the second valve can realize automatic water replenishment to the sealed water tank 3 according to the water level in the sealed water tank 3 .

[0049] Preferably, two sensors are provided, and the two sensors are respectively located at the upper and lower parts of the sealed water tank 3, corresponding to the highest water level line and the lowest water level line of the sealed water tank 3. When the water level in the sealed water tank 3 reaches the highest water level line, the sensor sends a high water level signal, and the high water level signal controls the second valve to close, and the water inlet pipe stops filling water into the sealed water tank 3. When the water level in the sealed water tank 3 reaches the lowest water level line, the sensor sends a low water level signal, and the low water level signal controls the second valve to open, and the water inlet pipe fills water into the sealed water tank 3, until the water level in the sealed water tank 3 reaches the highest water level line, and the sensor controls the second valve to close.

[0050] Therefore, the second valve can be automatically controlled in this way, thereby realizing the automatic water replenishment operation of the sealed water tank 3.

[0051] In this embodiment, preferably, the lower end of the sealing cover 2 is concentrically extended downward to be provided with a first sealing ring 21 and a second sealing ring 22, the first sealing ring 21 is located in the ring cooling trolley 1, and the second sealing ring 22 is at least partially immersed in the water of the sealing water tank 3 along the height direction;

[0052] The scraper 6 is fixedly connected to the lower end of the second sealing ring 22 .

[0053] The first sealing ring 21 and the second sealing ring 22 are provided to realize the labyrinth seal of the cold ring trolley 1, so as to prevent a large amount of flue gas from flowing into the upper part of the sealing water tank 3. Since the flue gas temperature in the cold ring trolley 1 is relatively high, a large amount of flue gas contacts the sealing water tank 3, which will cause the water in the sealing water tank 3 to evaporate and lose quickly, which may lead to the failure of the seal and also cause the waste of kinetic energy.

[0054] During the production process, the sealing water tank 3 rotates with the cold ring trolley 1. Since the cold ring trolley 1 and the sealing cover 2 are coaxially arranged, no matter how the relative positions of the sealing water tank 3 and the sealing cover 2 change, the lower part of the second sealing ring 22 of the sealing cover 2 is always immersed in the water of the sealing water tank 3, that is, the water surface in the sealing water tank 3 can always seal the gap between the sealing cover 2 and the cold ring trolley 1. Therefore, this water sealing method can easily achieve the sealing between the rotating part cold ring trolley 1 and the sealing cover 2 of the sealing part.

[0055] The scraper 6 is fixedly connected to the lower end of the second sealing ring 22, thereby fixing the scraper 6. When the sealed water tank 3 rotates with the cold ring trolley 1, the scraper 6 fixed to the second sealing ring 22 can generate relative movement with the sealed water tank 3, thereby enabling the scraper 6 to clean the sludge 11 along the bottom of the sealed water tank 3.

[0056] A method for sealing a water tank using an annular cooling device that is easy to clean, the method comprising:

[0057] Step 1, close the first valve 5, open the second valve, and inject water into the sealed water tank 3 through the water inlet pipe;

[0058] Step 2: As the cooling trolley 1 rotates, the scraper 6 drives the sludge 11 in the sealed water tank 3 to the inlet 41 of the cleaning pipe 4;

[0059] Step 3, opening the first valve 5 to discharge the sludge 11 in the cleaning pipe 4;

[0060] Step 4: close the first valve 5.

[0061] First, close the first valve 5 , and after opening the second valve, the water inlet pipe can inject water into the sealed water tank 3 . When the water level in the sealed water tank 3 reaches a certain height, it can cooperate with the sealing cover 2 to achieve a sealing effect on the ring cooling trolley 1 .

[0062] As production continues, solid particles in the flue gas in the cooling trolley 1 fall into the water in the sealed water tank 3, and these solid particles gradually settle and eventually fall to the bottom of the sealed water tank 3 to become sludge 11. As the cooling trolley 1 rotates, there is relative rotation between the scraper 6 and the sealed water tank 3. When the cooling trolley 1 rotates one circle, the scraper 6 can sweep along the bottom of the sealed water tank 3. Therefore, during the rotation of the cooling trolley 1, the scraper 6 cleans the sludge 11 at the bottom of the sealed water tank 3.

[0063] A cleaning pipe 4 is connected to the bottom of the sealed water tank 3. When the sludge 11 is pushed to the inlet 41 of the cleaning pipe 4 by the scraper 6, it will fall into the cleaning pipe 4 and gradually sink to the position of the first valve 5. As the sludge 11 continues to fall, the height of the sludge 11 in the cleaning pipe 4 gradually increases until the sludge 11 in the cleaning pipe 4 needs to be discharged.

[0064] When the first valve 5 is opened, the sludge 11 in the sewage cleaning pipe 4 will be discharged from the outlet 42 of the sewage cleaning pipe 4. As the sludge 11 is discharged, the boundary between the clean water 10 and the sludge 11 in the sewage cleaning pipe 4 will gradually move downward until all the sludge 11 is discharged and only the clean water 10 is left in the sealed water tank 3. At this time, the first valve 5 is closed.

[0065] At this point, the cleaning work of the sealed water tank 3 is completed, which is very convenient and easy to operate, and there is no need to stop production at all, and the cleaning work of the sludge 11 can be completed online.

[0066] In this embodiment, preferably, in step 3, when the first valve 5 is opened, water needs to be injected into the sealed water tank 3.

[0067] When the first valve 5 discharges the sludge 11, the water level in the sealed water tank 3 will gradually drop as the sludge 11 is discharged. Therefore, in order to avoid the problem of sealing failure caused by the drop in the water level in the sealed water tank 3, when the first valve 5 is opened, the second valve needs to be opened at the same time, so that while the sludge 11 is discharged, the water inlet pipe injects water into the sealed water tank 3 to maintain the water level in the sealed water tank 3.

[0068] Preferably, in order to avoid the problem that the water filling speed of the sealed water tank 3 is slower than the sewage discharge speed, resulting in the water level in the sealed water tank 3 being too low to achieve sealing, the sealed water tank 3 needs to be filled with water before opening the first valve 5.

[0069] In this embodiment, preferably, the first valve 5 is electrically connected to the second valve, and the first valve 5 controls the opening of the second valve.

[0070] The first valve 5 is electrically connected to the second valve, so that when the first valve 5 is manually opened, the second valve can be opened at the same time, thereby realizing the automatic water filling operation of the sealed water tank 3.

[0071] In one embodiment, a sensor is provided on the first valve 5 for detecting the switch state of the first valve 5 . When the first valve 5 is in an open state, the sensor sends a signal indicating that the first valve 5 is open. The signal controls the second valve to open, and the water inlet pipe injects water into the sealed water tank 3 .

[0072] In this embodiment, preferably, whether the sludge 11 is completely discharged is determined by observing the height of the sludge 11 in the cleaning pipe 4 .

[0073] There is a boundary line between clean water 10 and sludge 11 in the sewage cleaning pipe 4. By observing the movement of the boundary line, the discharge of the sludge 11 can be understood. When the boundary line between the sludge 11 and the clean water has moved below the first valve 5, the first valve 5 can be closed.

[0074] In this embodiment, preferably, in step one, the sensor is electrically connected to the second valve, and the sensor controls the water inlet pipe to automatically inject water into the sealed water tank 3 .

[0075] Two sensors are provided, and the two sensors are respectively located at the upper and lower parts of the sealed water tank 3, corresponding to the highest water level and the lowest water level of the sealed water tank 3. When the water level in the sealed water tank 3 reaches the highest water level, the sensor sends a high water level signal, which controls the second valve to close, and the water inlet pipe no longer flows into the sealed water tank 3. When the water level in the sealed water tank 3 reaches the lowest water level, the sensor sends a low water level signal, which controls the second valve to open, and the water inlet pipe flows into the sealed water tank 3 until the water level in the sealed water tank 3 reaches the highest water level, and the sensor controls the second valve to close.

[0076] Therefore, the second valve can be automatically controlled in this way, thereby realizing the automatic water replenishment operation of the sealed water tank 3.

[0077] In this embodiment, preferably, a soft scraper is provided at the bottom of the scraper 6 , and the soft scraper fits the bottom of the sealed water tank 3 .

[0078] In order to more effectively clean the sludge 11 at the bottom of the sealed water tank 3, a soft scraper is provided at the bottom of the scraper 6, and the soft scraper is in contact with the bottom of the sealed water tank 3. When the scraper 6 and the sealed water tank 3 move relative to each other, the soft scraper can more efficiently clean the sludge 11 at the bottom of the sealed water tank 3, so that more sludge 11 can be cleaned to the cleaning pipe 4.

[0079] In this embodiment, preferably, the width of the soft scraper is consistent with the width of the sealed water tank 3, and the two sides of the soft scraper are in contact with the two side walls of the water tank.

[0080] Preferably, a soft scraper is arranged on the outer ring of the scraper 6 to wrap the scraper 6 so that the soft scraper can contact the bottom and both sides of the sealed water tank 3 at the same time, thereby achieving a more comprehensive cleaning of the sealed water tank 3.

[0081] In this embodiment, preferably, the soft scraper is configured in a sheet shape or a brush shape.

[0082] In this embodiment, preferably, the outer wall of the sewage cleaning pipe 4 is set to be transparent.

[0083] Sludge 11 is stored in the cleaning pipe 4 . By setting the outer wall of the cleaning pipe 4 to be transparent, the height of the sludge 11 in the cleaning pipe 4 can be observed, and it can be judged whether the sealed water tank 3 needs to be cleaned.

[0084] In this embodiment, preferably, the outer wall of the cleaning pipe 4 is provided with scale lines.

[0085] After falling into the sewage cleaning pipe 4 , the sludge 1111 will settle downwards and continue to settle to the material of the sewage discharge valve 5 . Then, the sludge 1111 that falls in will accumulate upwards in sequence, and there will be a clear dividing line between the clean water 10 and the sludge 1111 .

[0086] The outer wall of the sewage cleaning pipe 4 is provided with scale lines. When the scale line between the clean water 10 and the sludge 1111 is close to the scale line on the outer wall of the sewage cleaning pipe 4, it indicates that the sewage cleaning pipe 4 needs to be cleaned.

[0087] Preferably, the scale line is arranged at a certain distance from the bottom of the sealed water tank 3 , so as to prevent the sludge 11 from accumulating in the sealed water tank 3 and affecting the rotation of the cooling trolley 1 .

[0088] The outer wall of the sewage cleaning pipe 4 is provided with scale lines, which is more conducive to the operator to observe the accumulation of sludge 11 in the sewage cleaning pipe 4.

[0089] In this embodiment, preferably, the outer wall of the sewage cleaning pipe 4 is provided with a sewage discharge line.

[0090] The outer wall of the cleaning pipe 4 is provided with a drainage line. When the height of the accumulated sludge 11 reaches or exceeds the drainage line, the cleaning pipe 4 must be cleaned to prevent the sludge 11 from accumulating at the bottom of the sealed water tank 3. The accumulated sludge 11 may interfere with the scraper 6 and affect the movement of the cold ring trolley 1.

[0091] In this embodiment, preferably, the bottom of the sealing groove is arranged to be inclined toward the connection between the cleaning pipe and the sealing groove, and the height of the sealing groove at the connection between the cleaning pipe and the sealing groove is arranged to be the lowest.

[0092] The bottom of the sealed water tank 3 is set to be inclined toward the connection between the sewage cleaning pipe 4 and the sealed water tank 3, so that the height of the connection between the sealed water tank 3 and the sewage cleaning pipe 4 is the lowest, which is conducive to the scraper 6 pushing the sludge 11 into the sewage cleaning pipe 4.

[0093] Furthermore, if the cleaning pipe 4 is not cleaned in time and the sludge 11 overflows into the sealed water tank 3 , the recessed position can also provide a suitable storage space for the sludge 11 , which can delay the interference between the sludge 11 and the scraper 6 to a certain extent.

[0094] Preferably, the height of the first valve 5 from the ground is set to 1-1.5 m, so that ordinary staff can operate the first valve 5 very conveniently.

However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0096] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
