Description

Technical Field

[0001] The present application relates to the technical field of converter steelmaking, and in particular to a sealing device for a feeding system. Background Art

[0002] During the converter steelmaking process, slag-making materials need to be added to the converter or ladle through the flux feeding system and the ferroalloy feeding system to react with harmful elements in the molten steel to form slag floating on the surface of the molten steel, thereby separating it from the molten steel and achieving the purpose of smelting. The material falls from the silo into the vibrating feeder, and then the vibrating feeder is fed into the weighing hopper through the weighing hopper receiving cover, and then added to the converter or ladle after weighing. Since the vibrating feeder needs to be inserted into the receiving cover, the receiving cover needs to have a hole. After the hole is opened, a large amount of dust will escape during the feeding process, which seriously affects the environment of the steelmaking workshop. In order to solve the problem of dust escaping, the usual practice is to install an asbestos rubber plate at the opening of the receiving cover. When installing the vibrating feeder on site, the rubber plate is opened according to the size of the vibrating feeder. This reduces the opening area and can prevent most of the dust from escaping.

[0003] However, the vibrating feeder discharges materials through motor vibration, so when drilling holes in the rubber plate, the amplitude of the vibrating feeder motor must be considered, and a 50mm gap is generally required. In this way, a large amount of dust will still escape from the gap when feeding. Therefore, it is necessary to improve the existing sealing device to completely solve the problem of dust escape. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a sealing device for a feeding system in view of the above-mentioned existing problems, so as to prevent dust from escaping during the feeding process.

[0005] The embodiment of the present application is implemented as follows:

[0006] An embodiment of the present application provides a feeding system sealing device, which is characterized in that it includes a feeding system flange, an opening flange of a receiving hood and a flexible sealing member. The feeding system flange is welded to the side of the front suspension of the feeder relative to the feeding direction, and both ends of the flexible sealing member are sealed and fixed between the feeding system flange and the opening flange of the receiving hood.

[0007] In some optional embodiments, the flexible seal is a flexible sleeve structure made of flexible material.

[0008] In some optional embodiments, the feeding system flange is formed by welding a plurality of sections of angle steel around a feeder unloading section to form an angle steel flange.

[0009] In some optional embodiments, both ends of the flexible seal are fixed to the feeding system flange and the receiving hood opening flange by means of pressure irons and fasteners.

[0010] In some optional embodiments, the fasteners are bolts, nuts and washers.

[0011] In some optional embodiments, the flexible material is industrial canvas.

[0012] The beneficial effects of the present application are as follows: a feeding system sealing device provided by the present application adds a flexible sealing structure between the vibrating feeder and the opening of the receiving cover, which completely eliminates the possibility of dust escaping without affecting the unloading of the feeder and the weighing of the weighing bucket; using industrial canvas instead of asbestos rubber sheet is more economical and helps to save costs.

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0018] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0019] The features and performance of the present application are further described in detail below in conjunction with the embodiments.

[0020] like Figure 1 As shown, the utility model provides a feeding system sealing device, including a feeding system flange 1, a receiving hood opening flange 2 and a flexible sealing member 3. The feeding system flange is welded to a side of a feeder front suspension 4 relative to a feeding direction, and both ends of the flexible sealing member are sealed and fixed between the feeding system flange and the receiving hood opening flange.

[0021] The flexible seal is a flexible sleeve structure made of flexible material. Both ends of the flexible seal are fixed to the flange of the feeding system and the opening flange of the receiving cover through a pressure iron 5 and a fastener 6.

[0022] The feeding system flange welded on the front hanging part of the vibrating feeder is not necessarily parallel to the opening flange of the receiving cover, and will change with the change of the feeding angle of the vibrating feeder. Due to the flexible seal, even if the feeding system flange of the vibrating feeder is not parallel to the opening flange of the receiving cover, it will not affect the production and installation of the sealing cover.

[0023] The flange of the feeding system is formed by welding multiple sections of angle steel around the unloading section of the feeder to form an angle steel flange.

[0024] The fasteners are bolts, nuts and washers. The flexible seal is installed between the flange of the feeding system and the flange of the opening of the receiving hood, compacted with a weight, and fastened with fasteners.

[0025] The flexible material can be industrial canvas, which is sewn into a predetermined shape. Since the industrial canvas is a flexible material, the desired shape can be sewn regardless of whether the flange of the feeding system is parallel to the opening flange of the receiving cover.

[0026] When the sealing device is in use and needs to be unloaded, the material in the silo 7 first falls into the vibrating feeder, and then is sent to the weighing hopper receiving cover through the vibrating feeder, and then falls into the weighing hopper 8. During the feeding process, the vibrating feeder and the receiving cover always maintain a soft connection, which will not affect the accuracy of the weighing result. The flange of the vibrating feeder feeding system and the opening flange of the receiving cover are sealed using industrial canvas, pressure iron, and fasteners, so that the material is always in a closed environment during the feeding process, and the escape of dust is completely prevented.
