Description

Technical Field

[0001] This utility model relates to the technical field of ore sintering preparation equipment, and more specifically, to a splash-proof device for the sealing groove of an annular cooler. Furthermore, this utility model also provides a liquid-sealed annular cooler including the aforementioned splash-proof device for the sealing groove. Background Technology

[0002] After the ore is sintered, the temperature of the hot sintered ore is usually between 600-900℃. It can only be transferred to the blast furnace after cooling treatment. Therefore, the sintering machine system needs to be equipped with corresponding cooling equipment.

[0003] Existing liquid-sealed ring coolers suffer from uneven material distribution and turbulent airflow during operation. The superposition of resonance and vibration waves causes the cooling water in the sealing groove to be disturbed and splashed, resulting in fluctuations in the water level in the sealing groove. This leads to water loss and a drop in the liquid level, requiring regular water replenishment and high maintenance frequency. In addition, the splashed cooling water can have adverse effects on the surrounding environment and equipment, such as corrosion.

[0004] In summary, how to reduce the cooling water loss of the sealing groove of the annular cooler is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a splash-proof device for the sealing groove of an annular cooler. A flexible hydrophobic plate is provided above and on the upper part of the liquid surface of the sealing groove, which can effectively reduce the superposition intensity of vibration waves and avoid resonance, thereby reducing the amount of cooling water loss caused by cooling water splashing.

[0006] In addition, this utility model also provides a liquid-sealed annular cooler including the above-mentioned anti-splash device for the sealing groove of the annular cooler.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A splash-proof device for a sealing groove of an annular cooler includes several flexible hydrophobic plates for suppressing the superposition intensity of vibration waves within the sealing groove. The flexible hydrophobic plates are detachably disposed on the inner wall of the sealing groove via connectors. At least one layer of the flexible hydrophobic plates is disposed along the height direction within the sealing groove. The highest layer of the flexible hydrophobic plates is higher than the maximum liquid level height of the sealing groove, and the lowest layer of the flexible hydrophobic plates is lower than the minimum liquid level height of the sealing groove.

[0009] Preferably, the connector includes a hydrophobic plate fixing seat arranged laterally on the inner wall of the sealing groove, the hydrophobic plate fixing seat is provided with a limiting part, the flexible hydrophobic plate is provided with a limiting hole, and the limiting part is snapped into the limiting hole.

[0010] Preferably, the limiting part is provided with an external thread, and a locking nut is fitted onto the external thread of the limiting part. The locking nut is used to press the flexible hydrophobic plate tightly against the hydrophobic plate fixing plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The core of this utility model is to provide a splash-proof device for the sealing groove of an annular cooler. A flexible hydrophobic plate is provided above and on the upper part of the liquid surface in the sealing groove, which can effectively reduce the superposition intensity of vibration waves and avoid resonance, thereby reducing the amount of cooling water loss caused by cooling water splashing.

[0028] In addition, this utility model also provides a liquid-sealed annular cooler including the above-mentioned anti-splash device for the sealing groove of the annular cooler.

[0029] This utility model provides a splash-proof device for the sealing groove of an annular cooler, including several flexible hydrophobic plates 1 for suppressing the superposition intensity of vibration waves in the sealing groove 10. The flexible hydrophobic plates 1 are detachably disposed on the inner wall of the sealing groove 10 through connectors. At least one layer of flexible hydrophobic plates 1 is provided in the sealing groove 10 along the height direction. The highest layer of flexible hydrophobic plates 1 is higher than the maximum liquid level height of the sealing groove 10, and the lowest layer of flexible hydrophobic plates 1 is lower than the minimum liquid level height of the sealing groove 10.

[0030] Please refer to Figure 1 Considering that when the liquid surface in the sealing tank 10 fluctuates up and down, the instantaneous height of the water wave must be higher than the height of the still liquid surface. In order for the flexible hydrophobic plate 1 to effectively suppress the vibration wave, the height of the flexible hydrophobic plate 1 should be the height of the still liquid surface of the cooling water in the sealing tank 10. Therefore, when the flexible hydrophobic plate 1 is provided in two or more layers, the highest layer of the flexible hydrophobic plate 1 should be higher than the maximum liquid surface height of the sealing tank 10, and the lowest layer of the flexible hydrophobic plate 1 should be higher than the minimum liquid surface height of the sealing tank 10.

[0031] It is understood that the above maximum liquid level and minimum liquid level are both static liquid level of the sealing tank 10. Usually, the above maximum liquid level is the liquid level of the sealing tank 10 after cooling water is added, and the minimum liquid level is the lowest liquid level at which the sealing tank 10 can operate normally.

[0032] Preferably, the flexible hydrophobic plates 1 can be uniformly arranged along the height direction of the sealing groove 10, and the spacing between two adjacent flexible hydrophobic plates 1 is 50-100mm.

[0033] The flexible hydrophobic plate 1 is detachably disposed on the inner wall of the sealing groove 10 via a connector. In order to obtain a better vibration wave suppression effect, it is preferable to set the lateral dimension of the flexible hydrophobic plate 1 to be 1 / 2 to 2 / 3 of the liquid surface dimension of the sealing groove 10.

[0034] Considering that the driving force of the vibration wave can be roughly assumed to be vertical when the liquid surface fluctuates up and down, the flexible hydrophobic plate 1 has the largest coverage area and the best suppression effect on the superposition intensity of vibration waves when it is set horizontally, with the size of the flexible hydrophobic plate 1 remaining unchanged.

[0035] In order to achieve the horizontal or near-horizontal setting of the flexible hydrophobic plate 1, the connector needs to provide a certain degree of support for the flexible hydrophobic plate 1, and the flexible hydrophobic plate 1 itself needs to have a certain degree of rigidity and its own weight should not be too heavy. Otherwise, the part of the flexible hydrophobic plate 1 without the support of the connector will tilt downward under its own weight.

[0036] The flexible hydrophobic plate 1 is made of a hydrophobic material or has a hydrophobic layer on its surface to prevent the cooling water in the sealing groove 10 from being absorbed into the flexible hydrophobic plate 1, which would reduce the amount of cooling water. The flexible hydrophobic plate 1 can be specifically set as an organic polymer plate, such as a polytetrafluoroethylene plate, a polypropylene plate, a rubber plate, a natural polymer material plate, and a polymer material plate, etc.

[0037] Considering factors such as cost and quality, the preferred flexible hydrophobic plate 1 typically includes at least one layer of flexible rubber sheet with a thickness of 1-3mm. The flexible rubber sheet is highly flexible, has good hydrophobic effect, strong corrosion resistance, and is lightweight and low in cost.

[0038] The connector is used to connect the flexible hydrophobic component 1 and the inner wall surface of the sealing groove 10, and to support the flexible hydrophobic component 1. Considering the replacement requirements of the flexible hydrophobic component 1, the connector and the flexible hydrophobic component 1 are detachably connected, such as by snap-fit ​​connection, threaded connection, pin connection, etc.

[0039] The connection between the connector and the sealing groove 10 does not require replacement or maintenance. It can be either a non-removable connection method such as welding or bonding, or a detachable connection method such as bolt, suction cup, or pin.

[0040] Considering that some connectors are immersed in cooling water for a long time, in order to extend the service life of the connectors, it is preferable to provide a rust-proof layer on the outer surface of the connectors. The rust-proof layer can be specifically set as a rust-proof paint layer, a metal plating layer, a chemical conversion film layer, etc. The rust-proof layer is used to enhance the corrosion resistance and oxidation resistance of the connectors.

[0041] The specific structure, shape, and size of the connector need to be determined based on the material, size, and quality of the flexible hydrophobic plate 1 in actual production, so as to ensure the supporting effect of the connector on the flexible hydrophobic plate 1.

[0042] In this embodiment, a flexible hydrophobic plate 1 is provided above and on the upper part of the liquid surface in the sealing tank 10. When the vibration wave generated by the turbulent airflow of the cooling water in the sealing tank 10 comes into contact with the flexible hydrophobic plate 1, the flexible hydrophobic plate 1 can absorb part of the energy of the vibration wave and reduce the superposition intensity of the vibration wave. It can also interfere with and scatter the vibration wave, weaken the superposition intensity of the vibration wave, and avoid the generation of resonance. In this way, the degree of vertical fluctuation of the liquid surface in the sealing tank 10 is reduced, and the amount of cooling water loss caused by the splashing of cooling water is effectively reduced.

[0043] In addition, when the vibration wave in the sealing groove 10 comes into contact with the flexible hydrophobic plate 1 above the liquid surface, the surface tension between the cooling water and the bottom surface of the flexible hydrophobic plate 1 can also consume part of the energy of the vibration wave, which is beneficial to weaken the superposition intensity of the vibration wave.

[0044] When at least one layer of flexible hydrophobic plate 1 is provided in the sealing groove 10, preferably, the installation directions of two adjacent layers of flexible hydrophobic plate 1 can be different in order to increase the overall coverage area of ​​the flexible hydrophobic plate 1.

[0045] When the sealing groove 10 is a cylindrical groove, each layer of flexible hydrophobic plate 1 can be uniformly arranged along the circumference of the sealing groove; when the sealing groove 10 is a rectangular groove, each layer of flexible hydrophobic plate 1 can be arranged sequentially on each inner wall surface of the sealing groove 10.

[0046] Of course, to simplify the installation of the flexible hydrophobic plate 1, adjacent layers of flexible hydrophobic plates 1 can also be arranged opposite each other, for example, please refer to Figure 1The flexible hydrophobic plate 1 is installed on the side of the sealing groove 10 and on the inner wall surface of the sealing groove 10 opposite to the sealing cover 101.

[0047] Based on the above embodiments, please refer to Figure 1 The connector includes a hydrophobic plate fixing seat 2 that is horizontally disposed on the inner wall of the sealing groove 10. The hydrophobic plate fixing seat 2 is provided with a limiting part 21, and the flexible hydrophobic plate 1 is provided with a limiting hole. The limiting part 21 is snapped into the limiting hole.

[0048] In this embodiment, the flexible hydrophobic plate 1 is snapped onto the hydrophobic plate fixing seat 2 by the snap-fit ​​connection of the limiting part 21 and the limiting hole. The structure is simple and easy to replace and disassemble.

[0049] Considering that the flexible hydrophobic plate 1 is relatively light, in order to prevent the flexible hydrophobic plate 1 from being dislodged from the limiting part 21 under the impact of water waves, a locking part can also be provided to fix the position of the flexible hydrophobic plate 1.

[0050] The locking component can be set as a locking nut. The limiting part 21 of the hydrophobic plate fixing seat 2 is provided with an external thread, and the locking nut is sleeved on the external thread of the limiting part 21. The locking nut is used to press the flexible hydrophobic plate 1 against the hydrophobic plate fixing plate 2.

[0051] The locking element can also be set as limit pin 3, please refer to [reference needed]. Figure 2 and Figure 3 The top of the limiting part 21 of the hydrophobic plate fixing seat 2 is provided with a limiting pin hole for installing the limiting pin 3. The distance from the limiting pin hole to the top surface of the hydrophobic plate fixing seat 2 is greater than the thickness of the flexible hydrophobic plate 1. The limiting pin 3 is used to restrict the upward movement of the flexible hydrophobic plate 1.

[0052] In addition to the aforementioned anti-splash device for the sealing groove of the annular cooler, this utility model also provides a liquid-sealed annular cooler that includes the anti-splash device for the sealing groove of the annular cooler disclosed in the above embodiments. The liquid-sealed water cooler includes a sealing groove 10, and the sealing groove 10 is provided with the anti-splash device for the sealing groove of the annular cooler disclosed in the above embodiments. For the structure of other parts of the liquid-sealed annular cooler, please refer to the prior art, which will not be repeated here.

[0053] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
