DETAILED DESCRIPTION

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: Reference Figure 1-Figure 3 A cooling furnace feed bin sealing device includes: a head flange 1, the inner wall of the head flange 1 is connected to the end side wall of the water-cooled inner ring 2, the other end side wall of the water-cooled inner ring 2 is connected to the inner wall of the water-cooled baffle ring 3, the side wall of the water-cooled baffle ring 3 is connected to the inner wall of the sealing outer ring 4, the head flange 1, the water-cooled inner ring 2, the water-cooled baffle ring 3 and the sealing outer ring 4 form a cold water cavity, and a set component is installed on the inner wall of the water-cooled inner ring 2.

[0023] The principles and beneficial effects of the above scheme are:

[0024] The set component is put on the positioning tube of the feed bin, and then the head flange 1 is connected to the feed bin with bolts. When feeding in the positioning tube of the feed bin, cold water is supplied to the cold water cavity composed of the head flange 1, the water-cooled inner ring 2, the water-cooled retaining ring 3 and the sealing outer ring 4. The cooperation between the set component and the head flange 1 improves the sealing effect of the device after installation. The cold water cavity can cool the feed bin to prevent the temperature from being too high during operation, which will cause the sealing effect of the device to decrease, thereby improving the safety of the working environment of personnel at the work site.

[0025] Example 2: Reference Figure 1-Figure 3 A water retaining ring 6 is installed on the side wall of the sealing outer ring 4 facing the end of the head flange 1.

[0026] The principles and beneficial effects of the above scheme are:

[0027] A water retaining ring 6 is mounted on the side wall of the sealing outer ring 4 facing the end of the head flange 1. The water retaining ring 6 can be in contact with the feed bin and improve the stability of the device after installation.

[0028] Example 3: Reference Figure 1-Figure 3 The other end side wall of the sealing outer ring 4 is provided with a chamfer.

[0029] The principles and beneficial effects of the above scheme are:

[0030] A chamfer is provided on the side wall of the other end of the sealing outer ring 4 to reduce the sharpness of the edge of the device and prevent the device from causing harm to personnel or equipment during transportation and lifting.

[0031] Example 4: Reference Figure 1-Figure 3 The set component includes: a bulk cotton tube 8, the inner wall of the water-cooled inner ring 2 contacts and cooperates with the side wall of the bulk cotton tube 8, and the two ends of the bulk cotton tube 8 contact and cooperate with a thermal insulation ring 7 respectively, and the side wall of the thermal insulation ring 7 is connected to the inner wall of the water-cooled inner ring 2.

[0032] The inner diameter of the heat insulation ring 7 is smaller than the inner diameter of the bulk cotton tube 8 .

[0033] The two thermal insulation rings 7 are connected via a thermal insulation inner ring 5 .

[0034] The side wall of the heat-insulating inner ring 5 is in contact with the inner wall of the loose cotton tube 8 .

[0035] The principles and beneficial effects of the above scheme are:

[0036] The thermal insulation inner ring 5 is sleeved on the positioning tube. After cold water is supplied to the cold water cavity, there is a temperature difference between the cold water cavity and the feed bin. The side wall of the bulk cotton tube 8 is arranged to contact and cooperate with the inner wall of the water-cooled inner ring 2 to prevent the temperature difference on both sides of the water-cooled inner ring 2 from being too large, which may cause local deformation of the structure. The two thermal insulation rings 7 cooperate with the thermal insulation inner ring 5 and the water-cooled inner ring 2 to fix the bulk cotton tube 8. The thermal insulation inner ring 5 may prevent the bulk cotton tube 8 from directly contacting the positioning tube of the feed bin and causing damage thereto.

[0037] Example 5: Reference Figure 1-Figure 3 The ends of multiple guide tubes 9 are equidistantly installed on the side wall of the water-cooled inner ring 2. A lifting plate 10 is slidingly sealed inside the guide tube 9. The bottom surface of the lifting plate 10 is connected to the side wall of the water-cooled inner ring 2 through a spring 11.

[0038] The top of the lifting plate 10 is rotatably connected to the bottom end of the screw 12, and the screw 12 is threadedly connected to a threaded block 13. One end of a pull rod 14 is hinged on both sides of the threaded block 13. The other end of one pull rod 14 is hinged to the end face of the head flange 1, and the other end of the other pull rod 14 is hinged to the end face of the water-cooling retaining ring 3.

[0039] The threaded block 13 is arranged above the other end of the pull rod 14 .

[0040] The principles and beneficial effects of the above scheme are:

[0041] On the basis of setting up the heat-insulating inner ring 5 and the loose cotton tube 8, a plurality of guide tubes 9 are also equidistantly installed on the side wall of the water-cooled inner ring 2. When the temperature difference between the cold water chamber and the feed bin positioning tube is too large, the local temperature in the cold water chamber is too high, and the volume of water expands rapidly, which will locally cause the distance between the head flange 1 and the water-cooled baffle ring 3 to increase. When the local temperature is too high, the spring 11 in the guide tube 9 expands due to heat, and the lifting plate 10 drives the screw 12 to rise, and further the screw 12 drives the threaded block 13 to rise, and the threaded block 13 drives the end of the pull rod 14 to rise, and the other end of one pull rod 14 drives the head flange 1 to reset, and the other pull rod 14 drives the water-cooled baffle ring 3 to reset, which can avoid the deformation of the head flange 1 and the water-cooled baffle ring 3 caused by the instantaneous increase in the local temperature of the cold water chamber, and further ensure the integrity of the structure in the device and the safety during operation; when the local temperature returns to normal , the spring 11 contracts and resets, and finally drives the pull rod 14 to reset, ending the tension applied to the head flange 1 and the water-cooled retaining ring 3. The simple structure is used to realize the self-adjustment of the device, thereby improving the applicability and practicality of the device; due to the threaded connection between the screw 12 and the threaded block 13, the height of the threaded block 13 is adjusted relative to the screw 12, and the height of the spring 11 is further adjusted. The lower the height of the spring 11, the greater its elastic force during operation, and the greater the tension applied to the head flange 1 and the water-cooled retaining ring 3. It is appropriate to set the spring 11 accordingly when the feed temperature of the feed bin is high. The higher the height of the spring 11, the smaller its elastic force during operation, and the smaller the tension applied to the head flange 1 and the water-cooled retaining ring 3. It is appropriate to set the spring 11 accordingly when the feed temperature of the feed bin is low, thereby further improving the applicability of the device.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
