Description

Technical Field

[0001] The utility model relates to the technical field of annular cooler equipment, in particular to a novel annular cooler silt removal device. Background Art

[0002] Annular cooler is an important process equipment in the metallurgical industry, such as Figure 1 The 425 m2 annular cooler shown is water-cooled and sealed, with a structure including a sealing water tank and sealing plates. During daily use, the annular cooler generates dust due to the blower during the material cooling process. This dust then forms sludge when it encounters the sealing water in the upper sealing water tank (this is a normal operating condition). After long-term operation, a large amount of sludge will form in the water tank, which is difficult to clean manually. This leads to the following problems during use:

[0003] 1. Affecting the sealing effect of the ring cooler. A large amount of sludge accumulates, forming pores inside. Due to the reduction of cooling water, the sealing performance will deteriorate.

[0004] 2. As the amount of silt increases, operators need to clean it frequently, which increases their labor intensity.

[0005] 3. Manual desilting during the operation of the ring cooler cannot guarantee personnel safety;

[0006] 4. Since silt is not removed at fixed points, the silt removed on site is directly treated as waste and is difficult to recycle;

[0007] 5. After the silt accumulates, some of the silt will clump together and cannot be cleaned manually, which will lead to increased compaction. When the sealing water is reduced, there will be a risk of damage to the sink. Utility Model Content

[0008] The purpose of the utility model is to provide a novel annular cooler silt clearing device, which can conveniently and thoroughly clean the accumulated dust and silt in the annular cooler water tank, thereby achieving good sealing and low-load stable operation of the annular cooler.

[0009] The above technical objectives of the present invention are achieved through the following technical solutions:

[0010] A new type of dredging device for an annular cooler includes a dredging inclined plate and a collecting hopper. A platform through-hole is provided on the water trough platform of the outer ring sealing plate of the annular cooler. The dredging inclined plate is tilted through the platform through-hole and then inserted into the annular cooling water trough. The tilting direction is opposite to the rotation direction of the annular cooler. A safety gap is left between the dredging inclined plate and the annular cooling water trough, and the upper end of the collecting hopper extends above the dredging inclined plate.

[0011] By adopting the above technical solution, the inclined direction of the dredging ramp can smoothly and steadily clean the silt from the water tank. Combined with the collection hopper, it is convenient to thoroughly clean the accumulated dust and silt in the water tank of the annular cooler, thereby achieving good sealing and low-load stable operation of the annular cooler.

[0012] Furthermore, the collecting hopper is located on the side of the dredging inclined plate away from the outer ring sealing plate of the annular cooler.

[0013] By adopting the above technical solution, the collecting hopper can conveniently collect the silt cleared from above the silt clearing inclined plate.

[0014] Furthermore, the upper end of the collecting hopper is connected to an upper communicating inclined pipe, and the upper communicating inclined pipe extends above the dredging inclined plate.

[0015] By adopting the above technical solution, the upper connecting inclined pipe extends to above the dredging inclined plate, and the silt above the dredging inclined plate is collected into the collecting hopper through the upper connecting inclined pipe.

[0016] Furthermore, the upper connecting inclined pipe includes an inclined pipe top plate at the upper end, and the inclined pipe top plate is located directly above the dredging inclined plate.

[0017] By adopting the above technical solution, the silt on the dredging inclined plate accumulates upward, and the accumulated silt is limited by the inclined tube top plate and enters the upper connecting inclined tube toward the side away from the outer ring sealing plate of the annular cooler for collection.

[0018] Furthermore, the inclined tube top plate is downwardly connected to an inclined tube side plate at one end away from the dredging inclined plate.

[0019] By adopting the above technical solution, the silt accumulated on the dredging inclined plate is restricted from entering the upper connecting inclined pipe outward through the inclined pipe top plate, inclined pipe side plates, the outer ring sealing plate of the annular cooler and the water tank platform, further facilitating the silt to enter the upper connecting inclined pipe toward the side away from the outer ring sealing plate of the annular cooler for collection.

[0020] Furthermore, the upper end of the upper connecting inclined tube expands upward along the width direction into a trumpet shape.

[0021] By adopting the above technical solution, the collection range of sludge by the upper connecting inclined pipe is improved.

[0022] Furthermore, the inclined tube top plate is located above the platform through-hole of the water tank platform.

[0023] By adopting the above technical solution, the collection of sludge from the bottom of the water tank platform to the top of the water tank platform is realized, which facilitates collection and improves the separation effect from water.

[0024] Furthermore, a plate-connected oblique support is connected to the water tank platform, and the upper end of the dredging oblique plate is connected to the outside of the plate-connected oblique support.

[0025] By adopting the above technical solution, the inclination and connection of the dredging inclined plate are achieved.

[0026] Furthermore, the lower end of the collecting hopper is connected to a recovery chute.

[0027] By adopting the above technical solution, the sludge material can be automatically recovered.

[0028] In summary, the present invention has the following beneficial effects:

[0029] The tilting direction of the dredging inclined plate can smoothly and steadily remove the silt from the water tank. In conjunction with the collection hopper, it can easily and thoroughly remove the accumulated dust and silt in the water tank of the annular cooler, achieving good sealing and stable operation of the annular cooler under low load. The collection hopper is located on the side of the dredging inclined plate away from the outer ring sealing plate of the annular cooler. Through the upper connecting inclined pipe, the inclined pipe top plate, the outer ring sealing plate of the annular cooler and the inclined pipe side plate, the silt is restricted from entering the upper connecting inclined pipe, making it convenient for the silt to enter the upper connecting inclined pipe for collection.

[0030] In summary, the silt removal device can remove the silt from the water tank smoothly and steadily. During the use of the silt removal device, there is no need for manual silt removal, which greatly reduces the labor intensity of the personnel on duty; the silt recovered by the silt removal device can reduce the frequency of personnel handling, and at the same time, it can be put into the mixer for the second time, indirectly achieving the purpose of cost saving; and because the silt in the water tank can flow, the situation of sealing plate damage caused by silt compaction is avoided.

[0035] The following is a further description of the specific embodiments of the present invention in conjunction with the accompanying drawings, which do not limit the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] A new type of ring cooler desilting device, such as Figure 2 As shown, it includes a dredging inclined plate 1 and a collecting hopper 2. A platform through-hole 3 is opened on the water trough platform of the outer ring sealing plate of the annular cooler. The dredging inclined plate 1 is tilted through the platform through-hole 3 and then inserted into the annular cooling water trough. Its tilting direction is opposite to the rotation direction of the annular cooler (in this embodiment, the annular cooling water trough rotates with the annular cooler. The dredging inclined plate 1 inserted downward in the opposite direction is used to collect sludge, so that the sludge is separated from the water below).

[0037] A safety gap is left between the dredging inclined plate 1 and the annular cooling water trough, and a gap is left between the upper side of the dredging inclined plate 1 and the platform through-hole 3 for silt to escape upward. The silt is collected above the trough platform. Specifically, the upper end of the collecting hopper 2 extends above the dredging inclined plate 1 and the trough platform.

[0038] As the cooling water trough rotates, the tilting direction of the dredging inclined plate 1 in this embodiment can smoothly and steadily scrape and clean the silt from the cooling water trough. The silt is separated from the water along the dredging inclined plate 1 and moves upward. In conjunction with the collecting hopper 2, the accumulated dust and silt in the cooling machine water trough can be conveniently cleaned thoroughly, thereby achieving good sealing and low-load stable operation of the cooling machine. In other embodiments, the cooling water trough is fixed, and the water trough platform rotates, and the dredging inclined plate 1 thereon rotates with the water trough platform to clean the cooling water troughs at different positions.

[0039] like Figure 2 and Figure 3 As shown, the collecting hopper 2 is located on the side of the silt removal inclined plate 1 away from the outer ring sealing plate of the annular cooler, and can be fixed to a fixed position such as the annular cooler frame, so that the collecting hopper 2 can collect the silt cleaned above the silt removal inclined plate 1. The lower end of the collecting hopper 2 in this embodiment is connected to a recovery chute 21 to facilitate automatic recovery of the silt material.

[0040] The upper end of the collecting hopper 2 is connected to the upper communicating inclined pipe 5, which extends to the top of the dredging inclined plate 1; the upper communicating inclined pipe 5 includes an inclined pipe top plate 51 at the upper end, which is located directly above the dredging inclined plate 1. The inclined pipe top plate 51 is downwardly connected to an inclined pipe side plate 52 at one end away from the dredging inclined plate 1. It can also be connected to the inclined pipe side plates 52 at both ends, one of which abuts against the upper side of the water tank platform and the other abuts against the upper side of the dredging inclined plate 1, forming a downwardly opening collecting space, so that the silt accumulated and moved upward is blocked by the inclined pipe side plates 52 and collected into the collecting hopper 2 through the communicating inclined pipe 5;

[0041] The upper connecting inclined pipe 5, the inclined pipe top plate 51, the annular cooler outer ring sealing plate and the inclined pipe side plate 52 are used to restrict the sludge from flowing outward into the upper connecting inclined pipe 5, thereby facilitating the collection of the sludge.

[0042] like Figure 2As shown, the upper end of the upper connecting inclined tube 5 (and the upper end of the collecting hopper 2) expands upward in the width direction into a trumpet shape, and the inclined tube top plate 51 is located above the platform through-hole 3 of the water tank platform; a plate connecting inclined support 4 is also fixedly connected to the water tank platform, and the upper end of the dredging inclined plate 1 is connected to the upper side of the plate connecting inclined support 4 by screws or plug-in.

[0043] Working principle:

[0044] This application selects a dredging fixed point in the annular cooler and transforms the outer ring sealing plate of the annular cooler, including opening a platform through-hole 3 on the water trough platform and installing a dredging inclined plate 1 in the annular cooler water trough, which is also the core part of this patent. The inclined installation direction of the lower end of the dredging inclined plate 1 is opposite to the rotation direction of the annular cooler, and a safety gap is left between the dredging inclined plate 1 and the water trough to ensure the normal operation of the equipment; after the dredging inclined plate 1 is installed, the collecting hopper 2 is installed along the external fixed sealing plate, and the recovery chute 21 is installed below the collecting hopper 2 to facilitate automatic recovery of materials.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
