Description

TECHNICAL FIELD

[0001] The utility model belongs to mechanical equipment technical field, concretely relates to a kind of furnace top sealing type coal-adding sleeve device in coking equipment. BACKGROUND

[0002] In the process of coke oven coking, coal needs to be guided from coal charging car into carbonization chamber. This process needs to be sealed tightly to prevent harmful gas from overflowing and polluting the environment during the coal charging process. Coal needs to be guided into the carbonization chamber by a coal-adding sleeve device to realize the sealing of the coal charging process. The original coal-adding sleeve device uses non-metallic flexible connection and packing seal form for sealing points, and uses spherical and conical sealing form for the lower part. The use of non-metallic flexible connection has the problems of short service life and high maintenance rate. The use of packing seal form can easily cause the upper and lower movements to be blocked, resulting in high equipment failure rate, and the packing seal requires frequent adjustment of the packing box, resulting in high maintenance rate. The lower part uses spherical and conical sealing, which has the problem of insufficient compensation for the horizontal direction error of the oven hole seat. Furthermore, the direct contact of the conical surface with the furnace body causes large deformation of the oven hole seat, thereby reducing the sealing effect. SUMMARY

[0003] The utility model provides a kind of new furnace top sealing coal-adding sleeve device, and the defects of original device are sealed in each sealing point of coal-adding sleeve device using metal material combination, long service life, smooth operation, low maintenance rate, good sealing effect. It can operate stably under high temperature, dust and strong corrosive working conditions.

[0004] To solve the above technical problems, the technical scheme adopted by the utility model is:

[0005] A new furnace top sealing coal-adding sleeve device mainly includes a fixed guide cylinder, a metal flexible connection, an intermediate sleeve, a cross ring sleeve, a movable sleeve, a discharging port, a blade, and a ceramic fiber rope. The components cooperate to form three sealing points. The first sealing point is a metal flexible connection seal. This sealing point is used to seal the fixed guide cylinder and the intermediate sleeve. The metal flexible connection is made of special stainless steel, which is resistant to high temperature and corrosion. It can also meet the axial expansion and contraction between the fixed guide cylinder and the intermediate sleeve.

[0006] The second sealing point is sealed by the cooperation of sealing ring one and sealing ring two. This sealing point is used to seal the intermediate sleeve and the movable sleeve. Sealing ring one is conical, and sealing ring two is spherical. Sealing ring one and sealing ring two are cut from metal materials that are resistant to high temperature and corrosion, ensuring the accuracy and roughness of the conical surface and the spherical surface. The cooperation of sealing ring one and sealing ring two can form a joint rotation form, which can compensate for the different shaft degrees of the intermediate sleeve and the movable sleeve.

[0007] The third sealing point adopts blade edge and ceramic fiber rope loop sealing, and is used for sealing the charging port and the furnace hole seat; when the ceramic fiber rope loop is in contact with the plane of the furnace hole seat, the ceramic fiber rope loop is deformed until the blade edge is in complete contact with the plane of the furnace hole seat, at this time, the two ceramic fiber rope loops and the three blade edges form a seal with the plane of the furnace hole seat, the ceramic fiber rope loop can compensate for the slight deformation in the plane of the furnace hole seat, and the sealing effect is ensured. After the coal charging is completed, the blade edge is separated from the furnace hole seat, and the ceramic fiber rope loop is elastically reset. The blade edge and the ceramic fiber rope loop are made of high-temperature-resistant and corrosion-resistant metal and non-metal, and have long service life and long maintenance period.

[0008] The cross loop can make the movable sleeve swing along the cross axis direction at will, so as to compensate for the unevenness of the whole furnace hole seat, and ensure the sealing effect.

[0009] The coal charging guide sleeve device has the advantages that: aiming at the sealing problem of the original coal charging sleeve device, each sealing point of the coal charging guide sleeve device adopts a metal material sealing form, 1. The sealing effect is good, and the pollution of high temperature and smoke dust to the environment is reduced. 2. The sealing point adopts metal material sealing, is high-temperature-resistant, and has long service life. 3. The structure can compensate for the unevenness and in-plane deformation of the furnace hole seat, and has strong working condition applicability. The coal charging guide sleeve device can stably operate under high-temperature, dusty and corrosive working conditions. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0018] The utility model discloses as shown in the figure Figures 1-7 The technical scheme and structural features in the utility model embodiment are described below with reference to the drawings:

[0019] As shown in the figure Figure 1 The fixed guide cylinder (2) is fixed on the flange at the lower end of the spiral discharge (1) by bolts. The upper flange of the metal flexible connection (4) is connected to the fixed guide cylinder (2) by bolts. The intermediate sleeve (7) is hung and installed below the fixed guide cylinder (2) through the metal flexible connection (4), the nut one (3), the boom (6), and the compression spring one (5). The sealing ring two (12) is fixed on the lower flange of the intermediate sleeve (7) by bolts. The sealing ring one (8) is fixed on the upper flange of the movable sleeve (11) by bolts. The discharge port (14) is connected to the lower flange of the movable sleeve (11) by bolts. The furnace hole seat (13) is fixed on the furnace top.

[0020] As shown in the figure Figure 2 The movable sleeve (11) is connected to the cross ring nest (9) through the rotating shaft one (10). The cross ring nest (9) is connected to the lifting frame (16) through the rotating shaft two (15).

[0021] As shown in the figure Figure 3 Two ceramic fiber rope rings (17) are embedded in the grooves of the bottom flange of the discharge port (14). Two ceramic fiber rope rings (17) are arranged at intervals with three blade edges (18) on the bottom flange of the discharge port (14). Two ceramic fiber rope rings (17) protrude above the horizontal plane of the three blade edges (18). The three blade edges (18) are processed to form an integral structure with the bottom flange of the discharge port (14).

[0022] The operation and function of the device are as follows:

[0023] As shown in the figure Figure 4 When coal needs to be loaded, the lifting frame (16) moves downward along the vertical direction under the action of driving force, and the lifting frame (16) carries the movable sleeve (11) to move downward at the same time. When the sealing ring one (8) and the sealing ring two (12) are in contact, the tapered surface on the sealing ring one (8) cooperates with the spherical surface of the sealing ring two (12) to form a seal, sealing the space between the intermediate sleeve (7) and the movable sleeve (11).

[0024] As attached Figure 5 As shown: When the lifting frame (16) continues to descend, the flexible metal connection (4) will stretch and extend, and the compression spring (5) will compress and shorten. This is to meet the axial compensation of the intermediate sleeve (7) and ensure that the sealing ring (8) and the sealing ring (12) are always in close contact. When the coal loading is completed and the lifting frame (16) moves upward, the sealing ring (8) and the sealing ring (12) separate, and the flexible metal connection resets under the action of the compression spring (5), and the intermediate sleeve (7) returns to its initial height.

[0025] As attached Figure 6 As shown: When the ceramic fiber rope loop (17) contacts the plane of the furnace hole seat (13), the ceramic fiber rope loop (17) deforms until the cutting edge (18) is in complete contact with the plane of the furnace hole seat (13). At this time, the two ceramic fiber rope loops (17) and the three cutting edges (18) form a seal with the plane of the furnace hole seat (13). The ceramic fiber rope loop (17) can compensate for the slight in-plane deformation of the upper plane of the furnace hole seat (13) and ensure the sealing effect. After the coal charging is completed, the cutting edge (18) separates from the furnace hole seat (13) and the ceramic fiber rope loop (17) elastically returns to its original position.

[0026] As attached Figure 2 Appendix Figure 7 As shown: When the furnace hole seat (13) is uneven, the movable sleeve (11) will swing along the first rotating shaft (10), and at the same time the cross ring (9) will swing along the second rotating shaft (15). At this time, the first sealing ring (8) will rotate with the first rotating shaft (10) and the second rotating shaft (15) as the pivot points and will always be in contact with the second sealing ring (12), forming a joint seal. This ensures the sealing effect of the sealing point.
