Description

Technical Field

[0001] The utility model relates to the technical field of coking, in particular to a guide sleeve sealing device for a top-loading coke oven coal charging car. Background Art

[0002] At present, the main measures to achieve smokeless coal loading in large top-loading coke ovens are high-pressure ammonia water and single-hole adjustment of the carbonization chamber. However, these two measures will be affected by the sealing of the coal loading guide sleeve and the furnace mouth, making it difficult to achieve smokeless coal loading.

[0003] In the past, the coal car was designed with the coal guide sleeve fixed on the coal car. When loading coal, the coal guide sleeve was aligned with the furnace mouth and dropped down, relying only on the coal guide sleeve and the furnace mouth, both of which were made of metal, to seal. This sealing method has poor sealing effect, often resulting in high oxygen content in the coal gas at the initial stage of coal loading, heavy smoke during coal loading, and poor working environment on the furnace top. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a guide sleeve sealing device for a top-loading coke oven coal charging car with good sealing effect in view of the deficiencies of the prior art.

[0005] In order to solve the above technical problems, the present invention includes:

[0006] A sealing device for a guide sleeve of a top-loading coke oven coal-charging car comprises a coal-charging guide sleeve, the bottom of which is fixedly connected to a port via a flange; the port comprises a lower portion inserted into a furnace opening and an upper portion located outside the furnace opening, an outer wall of the upper portion is fixedly provided with a circular fixing seat, and the bottom of the fixing seat is fixedly provided with a circular asbestos flange; the longitudinal section of the asbestos flange is a symmetrically distributed flat rectangle; the asbestos flange comprises an internal hard core and an asbestos layer uniformly wrapped around the outside of the hard core.

[0007] Furthermore, a plurality of reinforcing plates are evenly fixedly arranged along the circumferential direction between the top of the fixing seat and the outer wall of the port.

[0008] Furthermore, the outer wall of the port is spherical, and the inner wall of the port is conical.

[0009] Furthermore, the bottom of the fixing seat is a plane, the outer diameter of the asbestos flange is equal to the outer diameter of the fixing seat, and the inner diameter of the asbestos flange is larger than the inner diameter of the furnace mouth.

[0010] Furthermore, a plurality of bolts are evenly fixedly arranged on the top of the asbestos flange along the circumferential direction, and a plurality of through holes for the bolts to pass through are correspondingly opened on the fixing seat.

[0011] The beneficial effects of the utility model are:

[0012] The utility model is mainly used for large top-loading coke oven coal charging cars. On the basis of the original coal charging guide sleeve, an asbestos flange is added as a sealing gasket, which is clamped between the coal charging guide sleeve and the furnace mouth. The softness and fire resistance of the asbestos flange are utilized to improve the sealing between the coal charging guide sleeve and the coal charging mouth of the carbonization chamber, reduce the unorganized emission of the coal car during the coal loading process, improve the furnace top working environment, and at the same time reduce the oxygen content in the raw coal gas. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model;

[0014] In the figure: 1. Coal loading guide sleeve, 2. Fixed seat, 3. Asbestos flange. DETAILED DESCRIPTION

[0015] To facilitate understanding of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Those skilled in the art should understand that the embodiments are only intended to help understand the present invention and should not be considered as specific limitations of the present invention.

[0016] like Figure 1 As shown, the utility model provides a guide sleeve sealing device for a top-loading coke oven coal-charging car, comprising a coal-charging guide sleeve 1, the bottom of which is fixedly connected with a port through a flange, the outer wall of the port is spherical, and the inner wall of the port is a conical surface. The port comprises a lower part inserted into the furnace mouth and an upper part located outside the furnace mouth, a circular ring-shaped fixing seat 2 is fixedly arranged on the outer wall of the upper part, a plurality of reinforcing plates are evenly fixedly arranged between the top of the fixing seat 2 and the outer wall of the port along the circumferential direction, and a circular ring-shaped asbestos flange 3 is fixedly arranged on the bottom of the fixing seat 2; the longitudinal section of the asbestos flange 3 is a symmetrically distributed flat rectangle; the asbestos flange 3 comprises an internal hard core and an asbestos layer evenly wrapped outside the hard core.

[0017] The utility model adds an asbestos flange 3 to the outer side of the lower port of the coal loading guide sleeve 1. When the coal car is loading coal, the coal loading guide sleeve 1 is dropped, and the asbestos flange 3 is clamped between the furnace port and the coal loading guide sleeve 1 to act as a sealing gasket. The asbestos flange 3 has certain softness and fire resistance, which can ensure that it is not damaged by the high temperature of the carbonization chamber, effectively realizes better sealing between the coal loading guide sleeve 1 and the coal loading port, and avoids the situation that the raw coal gas has too high oxygen content and unorganized emission during the coal loading process due to poor sealing.

[0018] The fixing seat 2 is used to fix the asbestos flange, which is convenient for disassembly and replacement of the asbestos flange 3. The bottom of the fixing seat 2 is a plane, the outer diameter of the asbestos flange 3 is equal to the outer diameter of the fixing seat 2, and the inner diameter of the asbestos flange 3 is larger than the inner diameter of the furnace mouth. The top of the asbestos flange 3 is evenly fixed with multiple bolts along the circumference, and the fixing seat 2 is correspondingly provided with multiple through holes for the bolts to pass through.

[0019] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
