Description

TECHNICAL FIELD

[0001] The utility model relates to sintering ring cold field, specifically, relate to an easily cleaned ring cold equipment sealing water tank. BACKGROUND

[0002] Sintering ring cooling is the key link in the sintering process of iron ore, mainly used for the rapid cooling of the ore after high temperature sintering, to ensure that the physical and chemical properties of the ore meet the requirements of subsequent processing. There are a large amount of dust in the sintering ring cooling equipment, so the sintering ring cooling equipment needs to be sealed to avoid the overflow of dust in the equipment and affect the surrounding environment.

[0003] At present, the sintering ring cooling trolley is usually sealed by water sealing equipment, but a part of the dust in the ring cooling equipment will enter the sealing water tank and gradually deposit in the water tank to form sludge. Too much sludge will reduce the water volume in the sealing water tank. Since the temperature is relatively high during the sintering ring cooling, about 500-700℃, the reduction of water volume in the sealing water tank will easily lead to the evaporation of all the water in the water tank, which cannot realize the sealing effect.

[0004] And the cleaning of the sealing water tank also needs to be carried out in the gap of production stop, which needs to first drain all the water in the sealing water tank, and then manually remove the sludge at the bottom of the water tank, which is very inconvenient. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing an easily cleaned ring cold equipment sealing water tank, which can timely clean the sludge in the sealing water tank to the sludge cleaning pipe through the setting of the scraper, and the sludge in the sludge cleaning pipe can also be conveniently removed.

[0006] In order to realize the above-mentioned purpose, the utility model provides an easily cleaned ring cold equipment sealing water tank, which comprises a ring cooling trolley, a sludge cleaning pipe, a sealing cover arranged on the top of the ring cooling trolley and a sealing water tank matched with the sealing cover. The sealing water tank is arranged along the outer periphery of the top of the ring cooling trolley. The sealing water tank and the sealing cover cooperate to seal the ring cooling trolley. The sludge cleaning pipe is connected with the bottom of the sealing water tank. A sludge discharge valve is arranged on the sludge cleaning pipe.

[0007] The sealing cover is fixedly connected with a scraper, which is located at the lower end of the sealing cover and cooperates with the sealing water tank.

[0008] Preferably, the lower end of the sealing cover is concentrically extended downward to be provided with a first sealing baffle and a second sealing baffle. The first sealing baffle is located in the ring cooling trolley, and the second sealing baffle is at least partially located in the sealing water tank.

[0009] The scraper is fixedly arranged at the lower end of the second sealing baffle.

[0010] Preferably, the water level in the sealing tank is higher than the highest point of the scraper, and the second sealing baffle is at least partially immersed in the sealing tank.

[0011] Preferably, the bottom of the scraper is provided with a soft scraper blade, which is in close contact with the bottom of the sealing tank.

[0012] Preferably, the width of the soft scraper blade is consistent with the width of the sealing tank, and the two sides of the soft scraper blade are in close contact with the two side walls of the sealing tank.

[0013] Preferably, the soft scraper blade is arranged in a sheet shape or a brush shape.

[0014] Preferably, the outer wall of the cleaning pipe is transparent.

[0015] Preferably, the outer wall of the cleaning pipe is provided with a scale line.

[0016] Preferably, the outer wall of the cleaning pipe is provided with a sewage discharge line.

[0017] Preferably, the bottom of the sealing tank is inclined towards the connection between the cleaning pipe and the sealing tank, and the height of the sealing tank at the connection between the cleaning pipe and the sealing tank is the lowest.

[0018] According to the above technical scheme, the sealing cover is arranged on the top of the ring cooling trolley for sealing the ring cooling trolley. In actual production process, the ring cooling trolley rotates continuously, the sealing cover is coaxially arranged with the ring cooling trolley, and the sealing cover is stationary in the process of rotation of the ring cooling trolley. The outer periphery of the ring cooling trolley is provided with a sealing tank, a certain amount of water is injected into the sealing tank, the outer ring of the sealing cover is immersed in the sealing tank, and thus the water sealing of the ring cooling trolley is realized, so that the flue gas in the ring cooling trolley cannot overflow outward, thereby protecting the surrounding environment.

[0019] A scraper is fixed below the sealing cover and extends into the sealing tank. In the production process, the sealing tank rotates with the ring cooling trolley, while the scraper in the sealing tank remains stationary. Therefore, in the process of rotation of the sealing tank, the scraper and the sealing tank have relative motion, so that the scraper can push the sludge at the bottom of the sealing tank until the sludge is pushed to the position of the cleaning pipe. The sludge flows down along the cleaning pipe and finally accumulates above the sewage valve.

[0020] When the sealing tank needs to be treated, the sewage valve is opened, and the sludge accumulated in the cleaning pipe can be directly discharged. After the sludge is completely discharged, the sewage valve is closed.

[0021] Therefore, the easy-to-clean sealing water tank of the ring cooling equipment can realize reliable cleaning of the sludge generated in the production process and deposited at the bottom of the sealing water tank by arranging the scraper, so that a sufficient amount of water can be kept in the sealing water tank at all times for sealing the ring cooling trolley. The sludge cleaned by the scraper is stored in the sludge cleaning pipe, which has a certain capacity and can store the sludge generated in the production process until the sludge needs to be discharged, and the sludge cleaning work of the sealing water tank can be realized by opening the sludge discharge valve, so it is very convenient.

[0032] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not intended to limit the present application.

[0033] In the present application, unless otherwise stated, the orientation words contained in the terms such as "top, outer periphery, bottom, lower end, higher than, both sides, outer wall" only represent the orientation of the term in the conventional use state, or are commonly understood by those skilled in the art, and should not be considered as a limitation on the term.

[0034] Referring to Figure 1The easy-to-clean sealing water tank of the ring cooling equipment comprises a ring cooling trolley 1, a sealing cover 2 arranged on the top of the ring cooling trolley 1, a sewage pipe 4 and a sealing water tank 3 matched with the sealing cover 2, the sealing water tank 3 is arranged along the outer periphery of the top of the ring cooling trolley 1, the sealing water tank 3 is matched with the sealing cover 2 to seal the ring cooling trolley 1, the sewage pipe 4 is communicated with the bottom of the sealing water tank 3, and a sewage valve 5 is arranged on the sewage pipe 4.

[0035] The sealing cover 2 is fixedly connected with a scraper 6, the scraper 6 is located at the lower end of the sealing cover 2, and the scraper 6 is matched with the sealing water tank 3.

[0036] Through the implementation of the above technical scheme, the sealing cover 2 is arranged on the top of the ring cooling trolley 1 to seal the ring cooling trolley 1. In the actual production process, the ring cooling trolley 1 rotates continuously, the sealing cover 2 is coaxially arranged with the ring cooling trolley 1, the sealing cover 2 is stationary in the process of rotation of the ring cooling trolley 1, the outer periphery of the ring cooling trolley 1 is provided with the sealing water tank 3, 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, and thus the water sealing of the ring cooling trolley 1 is realized, so that the flue gas in the ring cooling trolley 1 cannot overflow outward, thereby protecting the surrounding environment.

[0037] The scraper 6 is fixed below the sealing cover 2 and extends into the sealing water tank 3. In the production process, the sealing water tank 3 rotates with the ring cooling trolley 1, while the scraper 6 in the sealing water tank 3 remains stationary. Therefore, in the process of rotation of the sealing water tank 3, the scraper 6 and the sealing water tank 3 have relative movement, so that the scraper 6 can push the sludge at the bottom of the sealing water tank 3 until the sludge is pushed to the position of the sewage pipe 4. The sludge will flow down along the sewage pipe 4 and finally accumulate at the position above the sewage valve 5.

[0038] When the sealing water tank 3 needs to be treated, the sludge accumulated in the sewage pipe 4 can be directly discharged by opening the sewage valve 5. After the sludge 11 is completely discharged, the sewage valve 5 is closed.

[0039] Therefore, the easy-to-clean sealing water tank of the ring cooling equipment can realize reliable cleaning of the sludge 11 generated in the production process and deposited at the bottom of the sealing water tank 3 by arranging the scraper 6, so that the sealing water tank 3 can always have enough water for sealing the ring cooling trolley 1. The sludge 11 cleaned by the scraper 6 is stored in the sewage pipe 4. The sewage pipe 4 has a certain capacity and can store the sludge 11 generated in the production process. When the sludge 11 needs to be discharged, the sewage valve 5 is opened to realize the cleaning work of the sludge 11 in the sealing water tank 3, without stopping production, and the cleaning work can be completed online, which is very convenient.

[0040] In this embodiment, preferably, the lower end of the sealing cover 2 is provided with a first sealing ring 21 and a second sealing ring 22, the first sealing ring 21 is located inside the annular cooling trolley 1, and the second sealing ring 22 is at least partially located inside the sealing water tank 3;

[0041] The scraper 6 is fixedly installed at the lower end of the second sealing ring 22.

[0042] A labyrinthine seal is achieved for the annular cooling trolley 1 by setting a first sealing ring 21 and a second sealing ring 22, preventing a large amount of flue gas from flowing into the top of the sealing water tank 3. Because the flue gas temperature inside the annular cooling trolley 1 is high, a large amount of flue gas contacting the sealing water tank 3 would cause the moisture inside the sealing water tank 3 to evaporate rapidly, potentially leading to seal failure and wasting kinetic energy.

[0043] The scraper 6 is fixedly connected to the lower end of the second sealing ring 22, thus fixing the scraper 6. When the sealing water tank 3 rotates with the cold ring trolley 1, the scraper 6 fixed to the second sealing ring 22 can move relative to the sealing water tank 3, thereby enabling the scraper 6 to clean the sludge 11 along the bottom of the sealing water tank 3.

[0044] In this embodiment, preferably, the water level in the sealing water tank 3 is higher than the highest point of the scraper 6, and the second sealing ring 22 is at least partially submerged in the sealing water tank 3.

[0045] By setting the second sealing ring 22 to be at least partially submerged in the sealing water tank 3, the purpose of sealing the annular cooling trolley 1 by the water in the sealing water tank 3 can be achieved.

[0046] During production, the sealing water tank 3 rotates with the annular cooling trolley 1. Since the annular cooling trolley 1 and the sealing cover 2 are coaxially arranged, regardless of the relative position of the sealing water tank 3 and the sealing cover 2, the lower part of the second sealing ring 22 of the sealing cover 2 is always submerged in the water in the sealing water tank 3. That is, the water level in the sealing water tank 3 can always seal the gap between the sealing cover 2 and the annular cooling trolley 1. Therefore, this water sealing method can easily achieve the seal between the rotating annular cooling trolley 1 and the sealing cover 2.

[0047] In this embodiment, preferably, a soft scraper is provided at the bottom of the scraper 6, and the soft scraper is in contact with the bottom of the sealing water tank 3.

[0048] 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. 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.

[0049] In this embodiment, preferably, the width of the soft blade is consistent with the width of the sealing water tank 3, and the two sides of the soft blade are in close contact with the two side walls of the water tank.

[0050] Preferably, the soft blade is arranged on the outer ring of the scraper 6 to wrap the scraper 6, so that the soft blade can be in contact with the bottom and the two sides of the sealing water tank 3 at the same time, thereby achieving more comprehensive cleaning of the sealing water tank 3.

[0051] In this embodiment, preferably, the soft blade is arranged in a sheet shape or a brush shape.

[0052] In this embodiment, preferably, the outer wall of the cleaning pipe 4 is transparent.

[0053] The cleaning pipe 4 stores sludge 11, and the transparent outer wall of the cleaning pipe 4 can observe the height of the sludge 11 in the cleaning pipe 4, and thus determine whether the sealing water tank 3 needs to be cleaned.

[0054] In this embodiment, preferably, the outer wall of the cleaning pipe 4 is provided with a scale line.

[0055] The sludge 11 falls into the cleaning pipe 4 and deposits downward and deposits to the sewage valve 5, and then the sludge 11 falls in turn and accumulates upward, and there is a clear boundary between the clean water 10 and the sludge 11.

[0056] The outer wall of the cleaning pipe 4 is provided with a scale line, and when the scale line between the clean water 10 and the sludge 11 is close to the scale line of the outer wall of the cleaning pipe 4, it indicates that the cleaning pipe 4 needs to be cleaned.

[0057] Preferably, the scale line is arranged at a distance from the bottom of the sealing water tank 3, so as to avoid the accumulation of sludge in the sealing water tank 3 and affect the rotation of the ring cooling trolley 1.

[0058] The outer wall of the cleaning pipe 4 is provided with a scale line, which is more conducive to the observation of the accumulation of the sludge 11 in the cleaning pipe 4.

[0059] In this embodiment, preferably, the outer wall of the cleaning pipe 4 is provided with a sewage line.

[0060] The outer wall of the cleaning pipe 4 is provided with a sewage line, and when the height of the accumulated sludge 11 reaches or exceeds the sewage line, the cleaning pipe 4 must be cleaned to avoid the accumulation of sludge 11 at the bottom of the sealing water tank 3, and the accumulated sludge 11 may interfere with the scraper 6 and affect the movement of the ring cooling trolley 1.

[0061] In this embodiment, preferably, the bottom of the sealing tank is inclined towards the connection between the sewage pipe and the sealing tank, and the height of the sealing tank at the connection between the sewage pipe and the sealing tank is the lowest.

[0062] The bottom of the sealing tank 3 is arranged to be inclined towards the connection between the cleaning pipe 4 and the sealing tank 3, so that the height of the connection between the sealing tank 3 and the cleaning pipe 4 is the lowest, which is beneficial to the pushing of the scraper 6 to the sludge 11 into the cleaning pipe 4.

[0063] Moreover, if the cleaning pipe 4 cannot be cleaned in time so that the sludge 11 overflows into the sealing tank 3, the recessed position can also provide appropriate storage space for the sludge 11, and can delay the interference between the sludge 11 and the scraper 6 to a certain extent.

[0064] Preferably, the height of the sewage valve 5 from the ground is arranged to be 1-1.5m, so that the sewage valve 5 can be conveniently operated by the general staff.

[0065] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the specific details in the above-described embodiments, and various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0066] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present application will not further describe various possible combination manners.
