Description

Technical Field

[0001] This utility model relates to the field of coking technology, and in particular to a sealing connection structure for a dust removal hood of a coke pusher. Background Technology

[0002] The coke oven pusher is one of the main pieces of equipment in coke oven production. Its main function is to remove the oven door and complete the coke pushing and coal charging operations. During the coke oven's coke discharge and coal charging processes, a large amount of dust-laden flue gas is emitted. Generally, the pusher is equipped with a dust hood for collecting flue gas directly above the pusher rod and leveling rod. Additionally, the top of the coke oven's carbonization chamber has a baffle plate to prevent flue gas from escaping. However, since the coke oven is a stationary device while the pusher is a mobile device, a fixed seal cannot be achieved between the two. A certain gap must be left to prevent the dust hood baffle plate from rubbing against the coke oven's baffle plate during the pusher's movement, which could affect the normal production of the coke oven.

[0003] Because the dust collector hood of the coke pusher car and the smoke baffle of the coke oven cannot be tightly sealed, and due to the thermal buoyancy of the high-temperature flue gas generated during coke pushing and coal leveling, a large portion of the flue gas will escape from between the smoke baffle of the dust collector hood of the coke pusher car and the smoke baffle of the coke oven, thus failing to achieve a good flue gas collection and treatment effect and causing certain environmental pollution.

[0004] Currently, coking plants employ two methods to seal the dust collector hood and smoke baffle of the coke pusher car with the smoke baffle of the coke oven body. One method involves a movable design for the front smoke baffle of the dust collector hood. During vehicle movement, the front smoke baffle of the dust collector hood retracts, while during coke pushing and coal loading, the front smoke baffle of the dust collector hood opens and directly contacts the smoke baffle of the coke oven body, preventing scraping during vehicle movement. However, because the baffle plate is prone to deformation, and both the dust collector hood smoke baffle and the coke oven body smoke baffle are made of rigid materials such as steel plates, the two cannot be completely fitted together, and there is still a problem of flue gas leakage. Another method involves installing flexible connections such as asbestos cloth on the front baffle plate of the coke pusher car dust collector, with the flexible connections slightly longer than the gap between the dust collector hood and the baffle plate to achieve a seal. However, because the flue gas temperature is high at this location, the asbestos cloth will deform after being burned, becoming brittle and fragile, resulting in a very short service life. At the same time, when the flexible connections are dragged on the baffle plate, the deformation of the baffle plate can easily scratch the flexible connections, or even scrape off the baffle plate of the coke oven body. Therefore, this method has the problems of short service life and high safety risks. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sealing connection structure for the dust collector hood of a coke pusher, which overcomes the deficiencies of existing technologies and effectively solves the problems of poor sealing effect, short service life, and high safety risks of the smoke baffle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sealing connection structure for a dust collector cover of a coke pusher includes a channel steel, with a fixed steel plate welded to the top and bottom of the channel steel, and a heat-resistant rubber sheet provided on one side of the outer wall of the fixed steel plate. Fixed bolts distributed at equal intervals are fixedly connected between the fixed steel plate and the heat-resistant rubber sheet.

[0008] The heat-resistant rubber sheet is fixedly connected to a spring that is evenly distributed at one end near the fixed steel plate. The heat-resistant rubber sheet is composed of an oblique sheet, a pressing sheet, and a front-curved sheet, wherein the pressing sheet is located between the oblique sheet and the front-curved sheet.

[0009] Preferably, the outer walls of both the fixing steel plate and the heat-resistant rubber sheet are provided with equally spaced mounting holes, and the fixing bolts are inserted through the interior of the mounting holes.

[0010] Preferably, symmetrically distributed reinforcing rods are welded between the channel steel and the fixed steel plate.

[0011] Preferably, a dust collector and smoke baffle is fixedly connected to one side of the outer wall of the channel steel.

[0012] Preferably, a coke oven steel column is provided on the other side of the channel steel, and a coke oven body smoke baffle is fixedly connected to the outer wall of one side of the coke oven steel column.

[0013] Preferably, a clamping area is provided between the two pressing plates, and the smoke baffle of the coke oven body is slidably connected to the inner wall of the clamping area.

[0014] Preferably, the spring is in a compressed state.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The sealing connection structure of the coke pusher car dust hood in this design is mainly composed of channel steel and heat-resistant rubber to form a "duckbill" structure. The coke oven body smoke baffle is placed in the middle of the "duckbill" structure formed by the heat-resistant rubber, so that the heat-resistant rubber is tightly attached to the coke oven body smoke baffle. This creates a leak-free sealing structure between the coke pusher car dust hood smoke baffle and the coke oven body smoke baffle, improving the sealing performance of the coke pusher car dust hood, reducing the leakage of flue gas caused by thermal buoyancy, and avoiding damage to the coke oven smoke baffle that could cause safety accidents. It has a high safety factor.

[0017] 2. The sealing connection structure of the coke pusher car dust hood in this design has a front-curved skin at the front end of the heat-resistant rubber sheet, which can reduce the difficulty of the coke oven body smoke baffle sliding into the clamping plate area. When the coke pusher car enters the furnace area, it can automatically clamp the coke oven body smoke baffle between the "duckbill" formed by the heat-resistant rubber sheet without manual intervention. At the same time, the multiple compressions of the heat-resistant rubber sheet can keep the two heat-resistant rubber sheets in a close state for a long time, thereby extending the service life of the sealing connection structure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, refer to Figure 1-2 A sealing connection structure for a dust removal hood of a coke pusher includes a channel steel 1, with fixed steel plates 2 welded to the top and bottom of the channel steel 1, and a heat-resistant rubber sheet 3 provided on one side of the outer wall of the fixed steel plate 2. Fixed bolts 4 are fixedly connected between the fixed steel plate 2 and the heat-resistant rubber sheet 3 at equal intervals.

[0025] In this embodiment, the main body is composed of a "duckbill" structure made of channel steel 1 and heat-resistant rubber 3. The coke oven body baffle 13 is placed in the clamping area 14 in the middle of the "duckbill" structure formed by the heat-resistant rubber 3, so that the heat-resistant rubber 3 is tightly attached to the coke oven body baffle 13. This forms a leak-free sealing structure between the dust baffle 11 of the coke pusher car and the dust baffle 13 of the coke oven body, improving the sealing performance of the dust baffle of the coke pusher car, reducing the leakage of flue gas caused by thermal buoyancy, and avoiding damage to the coke oven baffle that could cause a safety accident. The safety factor is high.

[0026] Example 2, refer to Figure 3 A sealing connection structure for a dust cover of a coke pusher car, wherein a heat-resistant rubber sheet 3 is fixedly connected to a spring 5 that is evenly distributed at one end near the fixed steel plate 2. The heat-resistant rubber sheet 3 is composed of an oblique sheet 6, a pressure sheet 7 and a front-curved sheet 8, wherein the pressure sheet 7 is located between the oblique sheet 6 and the front-curved sheet 8.

[0027] In this embodiment, a front-curved skin 8 is provided at the front end of the heat-resistant rubber sheet 3, which can reduce the difficulty of the coke oven body smoke baffle 13 sliding into the clamping plate area 14. When the coke pusher enters the furnace area, it can automatically clamp the coke oven body smoke baffle 13 between the "duckbill" formed by the heat-resistant rubber sheet 3 without manual intervention. At the same time, the multiple compressions of the heat-resistant rubber sheet 3 can keep the two heat-resistant rubber sheets 3 in a close state for a long time, thereby extending the service life of the sealing connection structure.

[0028] Reference Figure 4 The outer walls of the fixed steel plate 2 and the heat-resistant rubber 3 are provided with equally spaced mounting holes 9, and the fixing bolts 4 are inserted through the mounting holes 9.

[0029] Reference Figure 3 Symmetrically distributed reinforcing rods 10 are welded between the channel steel 1 and the fixed steel plate 2.

[0030] Reference Figure 1 A dust collector and smoke baffle 11 is fixedly connected to one side of the outer wall of the channel steel 1.

[0031] Reference Figure 1 On the other side of the channel steel 1, a coke oven steel column 12 is provided, and a coke oven body smoke baffle 13 is fixedly connected to the outer wall of one side of the coke oven steel column 12.

[0032] Reference Figure 3 A clamping area 14 is provided between the two pressing sheets 7, and the smoke baffle 13 of the coke oven body is slidably connected to the inner wall of the clamping area 14.

[0033] Reference Figure 3 Spring 5 is under compression.

[0034] Working principle: The main body is composed of a "duckbill" structure made of channel steel 1 and heat-resistant rubber 3. This component is fastened to the front end of the smoke baffle 11 of the coke pusher car dust hood by fixing bolts 4. The smoke baffle 13 of the coke oven body is placed in the middle of the "duckbill" component formed by the heat-resistant rubber 3, so that the heat-resistant rubber 3 is in close contact with the smoke baffle of the oven body, thereby forming a leak-free sealing structure between the smoke baffle 11 of the coke pusher car dust hood and the smoke baffle 13 of the coke oven body in the vertical direction.

[0035] Meanwhile, in order to facilitate the automatic combination of the "duckbill" component of the dust collector baffle plate 11 of the coke pusher car with the smoke baffle plate 13 of the coke oven body when entering the coke oven area, the heat-resistant rubber sheets 3 at both ends of the dust collector baffle plate 11 of the coke pusher car are set into a close-to-each shape along the longitudinal direction. This makes the gap between the "duckbill" formed by the two rubber sheets gradually transition from the maximum to a tight fit. This allows the coke pusher car to automatically clamp the smoke baffle plate 13 of the coke oven body between the "duckbill" formed by the heat-resistant rubber sheets 3 when entering the oven area, without the need for manual intervention.
