Description

Technical Field

[0001] The utility model relates to a split hopper sealing structure, belonging to the technical field of sealing technology. Background Art

[0002] At present, the existing hopper sealing structure realizes its sealing effect by combining a steel structure with a certain proportion of soft materials. During the sealing process, the fixed hopper is located above the dry quenching furnace without moving. Among them, the electric cylinder is responsible for opening the furnace cover and moving the movable hopper to the position above the dry quenching furnace for coke charging. During coke charging, the fixed hopper and the movable hopper are butted, and the center lines of the fixed hopper, the movable hopper and the dry quenching furnace are completely coincident. At the same time, the hopper sealing structure located on the lower flange surface of the fixed hopper and the upper flange surface of the movable hopper moves accordingly to complete the sealing. This kind of structure is extremely easy to cause the sealing effect to fail due to cyclic stress or extrusion deformation under long-term reciprocating motion, and due to the characteristics of its structure, the later maintenance is more cumbersome and the working hours required for maintenance are longer. Content of the Utility Model

[0003] In order to solve the technical problems existing in the prior art, the utility model provides a split hopper sealing structure with simple structure, reasonable design, reliable sealing and convenient maintenance.

[0004] To achieve the above object, the technical solution adopted by the utility model is a split hopper sealing structure, which includes a fixed upper hopper and a movable lower hopper. An upper joint plate is installed on the circumference of the bottom opening of the fixed upper hopper, and a lower joint plate is installed on the circumference of the top opening of the movable lower hopper. The upper joint plate and the lower joint plate are of the same size. One end of the upper joint plate is installed with a first elastic sealing plate. Oppositely, one end of the lower joint plate far from the first elastic sealing plate is installed with a second elastic sealing plate. Third sealing plates are respectively installed on both sides of the upper joint plate, and one end of the third sealing plate is connected with the first elastic sealing plate. Fourth sealing plates are respectively installed on both sides of the lower joint plate, and one end of the fourth sealing plate is connected with the second elastic sealing plate. The lengths of the third sealing plate and the fourth sealing plate are both 1 / 2 of the lengths of the upper joint plate and the lower joint plate. When the fixed upper hopper and the movable lower hopper are butted, the first elastic sealing plate, the second elastic sealing plate, the third sealing plate and the fourth sealing plate form an annular sealing structure.

[0005] Preferably, the first elastic sealing plate, the second elastic sealing plate, the third sealing plate and the fourth sealing plate have the same structure, are all made of heat-resistant stainless steel, and a semi-circular groove is arranged in the middle of the first elastic sealing plate, the second elastic sealing plate, the third sealing plate and the fourth sealing plate along the length direction.

[0006] Preferably, when the fixed feeding hopper and the movable discharging hopper are butted, a gap is reserved between the upper joint plate and the lower joint plate, and the width of the gap is the same as the diameter of the semi-circular groove.

[0007] Compared with the prior art, the utility model has the following technical effects: The structure of the utility model is simple and reasonably designed. Its structure is simpler, more durable and has lower maintenance cost compared with the existing sealing structure. The material of the adopted elastic sealing plate is heat-resistant stainless steel, and its cross-sectional dimension is similar to the semi-circular structure of the corrugated pipe, with excellent elastic performance, good sealing performance and not easy to accumulate dust and other advantages.

[0012] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0013] As Figures 1 to 4 shown, a split hopper sealing structure includes a fixed feeding hopper 1 and a movable discharging hopper 2. An upper joint plate 3 is installed on the circumference of the bottom opening of the fixed feeding hopper 1, and a lower joint plate 4 is installed on the circumference of the top opening of the movable discharging hopper 2. The upper joint plate 3 and the lower joint plate 4 are of the same size. One end of the upper joint plate 3 is installed with a first elastic sealing plate 5. Correspondingly, one end of the lower joint plate 4 far from the first elastic sealing plate is installed with a second elastic sealing plate 6. Third sealing plates 7 are respectively installed on both sides of the upper joint plate 3. One end of the third sealing plate 7 is connected to the first elastic sealing plate 5. Fourth sealing plates 8 are respectively installed on both sides of the lower joint plate 4. One end of the fourth sealing plate 8 is connected to the second elastic sealing plate 6. The lengths of the third sealing plates 7 and the fourth sealing plates 8 are both 1 / 2 of the lengths of the upper joint plate 3 and the lower joint plate 4. When the fixed feeding hopper 1 and the movable discharging hopper 2 are butted, the first elastic sealing plate 5, the second elastic sealing plate 6, the third sealing plates 7 and the fourth sealing plates 8 form an annular sealing structure.

[0014] The utility model adopts the method of respectively installing an upper joint plate 3 and a lower joint plate 4 on the contact surfaces of the fixed feeding hopper 1 and the movable discharging hopper 2, and then installing a first elastic sealing plate 5, a second elastic sealing plate 6, a third sealing plate 7 and a fourth sealing plate 8 on the upper joint plate 3 and the lower joint plate 4. In this way, when the fixed feeding hopper 1 and the movable discharging hopper 2 are butted, the first elastic sealing plate 5, the second elastic sealing plate 6, the third sealing plate 7 and the fourth sealing plate 8 form an annular sealing structure, thereby realizing the sealing of the hopper.

[0015] Among them, the first elastic sealing plate 5, the second elastic sealing plate 6, the third sealing plate 7 and the fourth sealing plate 8 have the same structure, are all made of heat-resistant stainless steel, and a semi-circular groove 9 is arranged in the middle of the first elastic sealing plate 5, the second elastic sealing plate 6, the third sealing plate 7 and the fourth sealing plate 8 along the length direction. When the fixed feeding hopper 1 and the movable discharging hopper 2 are butted, a gap is reserved between the upper joint plate 3 and the lower joint plate 4, and the width of the gap is the same as the diameter of the semi-circular groove 9. The first elastic sealing plate 5, the second elastic sealing plate 6, the third sealing plate 7 and the fourth sealing plate 8 are made of heat-resistant stainless steel and are provided with the semi-circular groove 9, and the semi-circular groove 9 is matched with the gap reserved between the upper joint plate 3 and the lower joint plate 4. In this way, when the fixed feeding hopper 1 and the movable discharging hopper 2 are butted, a turbulent flow cavity can be formed along with the falling of the material, thereby ensuring the sealing.

[0016] The above are only the preferred embodiments of the utility model, and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the scope of the utility model.
