Description

Technical Field

[0001] This invention belongs to the field of metallurgical slag treatment technology, and in particular relates to an auxiliary device for tilting slag pots. Background Technology

[0002] Slag handling systems in the metallurgical industry require tilting devices to automatically feed slag pots into processing containers, achieving safe, convenient, and stable operation while also addressing the issue of crane operating rates in workshops. On June 4, 2009, the State Intellectual Property Office published an invention patent (CN101565764A) entitled "A Slag Pot Tilting and Feeding Device." This patent describes a device for tilting a slag pot with two trunnions. The device includes two translation devices mounted on two parallel support beams, at least two clamping mechanisms, a supporting tilting frame, two transmission devices, and at least one locking mechanism. This device can gradually tilt a slag pot containing metallurgical slag, automatically feeding it into the slag processing container. The supporting tilting frame is a crucial component of this device. While the tilting frame can support slag pots of a specific design and size, steel plants may have several or more types and sizes of slag pots. In order to optimize the allocation of environmental protection resources, steel mills hope that the same slag treatment equipment can accommodate different slag pot types and sizes, but the current level of technology cannot yet realize this hope. Summary of the Invention

[0016] This invention provides a slag pot tilting auxiliary device, which can replace a large slag pot when installed on a slag pot tilting and feeding device. When operating a large slag pot, the tilting auxiliary device is not needed; the large slag pot can be directly installed on the tilting and feeding device.

This invention enables the same slag processing equipment to accommodate different slag pot types and sizes. Attached Figure Description

[0022] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 A slag pot tilting auxiliary device is disclosed, which can replace the large slag pot 20 and be installed on the slag pot tilting and feeding device. When the large slag pot 20 needs to be operated, the slag pot tilting auxiliary device is not required, and the large slag pot 20 can be directly installed on the slag pot tilting and feeding device. When the small slag pot needs to be operated, the slag pot tilting auxiliary device needs to be installed on the slag pot tilting and feeding device, that is, the small slag pot 3 is installed on the slag pot tilting and feeding device through the slag pot tilting auxiliary device, thereby enabling the small slag pot 3 to be used on the slag pot tilting and feeding device using the large slag pot 20.

[0024] In this embodiment, the auxiliary device includes a tilting support frame and several clamping mechanisms.

[0025] The construction of the tilting support frame is not limited, as long as it can replace the large slag pot 20 and be installed on the slag pot tilting and feeding device. The construction of the tilting support frame and the large slag pot 20 is similar, identical, or partially identical. In this embodiment, the tilting support frame includes a support frame body 2, and the two outer sides of the support frame body 2 are coaxially provided with first trunnions 1; furthermore, the first trunnions 1 are disposed on the outer side of the support frame body 2 through a first mounting support 6. During installation, the small slag pot 3 is located at the bottom 21 of the support frame body 2.

[0026] The large slag pot 20 includes a slag pot body 201, two second trunnions 202, and two second mounting supports 203. The two second trunnions 202 are respectively mounted on both sides of the slag pot body 201 via the two second mounting supports 203. The two first trunnions 1 are identical to the two second trunnions 202, and the two first mounting supports 6 are identical to the two second mounting supports 203. This embodiment does not require a specific structure for the support frame body 2; it can be the same as or different from the slag pot body 201. In this embodiment, the support frame body 2 is a welded structural component with a U-shaped structure. Several clamping mechanisms are arranged on the support frame body 2 to lock the small slag pot 3 onto the tilting support frame body 2.

[0027] Clamping mechanisms are a mature technology in this field, and this invention does not impose specific limitations on them. This invention does not limit the number of clamping mechanisms included in the auxiliary device, nor does it limit their placement, as long as they can clamp the small slag pot 3. In this embodiment, the auxiliary device includes two side clamping mechanisms 7 and one rear clamping mechanism 4. The two side clamping mechanisms 7 are used to clamp the lower sides of the small slag pot 3, and the rear clamping mechanism 4 is used to press the upper opening 31 of the small slag pot 3. The two side clamping mechanisms 7 and the rear clamping mechanism 4 form a three-point balanced clamping, locking the small slag pot 3 onto the tilting support frame. In this embodiment, the structures of several clamping mechanisms are identical, each including a drive unit 71, a linkage mechanism 72, and a claw 73. The drive unit 71 is drivenly connected to the claw 73 through the linkage mechanism 72. The drive unit 71 can be a hydraulic cylinder, an electro-hydraulic actuator, or an electric cylinder, etc., and this invention does not limit this; this embodiment prefers an electro-hydraulic actuator. This example does not impose a specific limit on the number of links in the linkage mechanism 72; it can be one or more, depending on actual usage requirements. The key is that the drive unit 71 drives the chuck 73 via the linkage mechanism 72, enabling the chuck 73 to clamp or release the small slag pot 3.

[0028] The inner wall of the support frame body 2 is provided with a plurality of hinge supports for installing the clamping mechanism. For example, the drive part 71 is hinged to the inner wall of the support frame body 2 through the first hinge support 8, the middle part of the claw 73 is hinged to the inner wall of the support frame body 2 through the second hinge support 5, and one end of the claw 73 is hinged to the linkage mechanism 72.

[0029] In this embodiment, the clamping mechanism has a self-locking function when clamped, which can ensure the safety and reliability of the small slag tank 3 when it is overturned.

[0030] Since the small slag pot 3 is installed at the front position of the tilting support frame (i.e., at the front end of the support frame body 2), the rear end of the tilting support frame body 2 is provided with a counterweight 9 via a connecting seat 10.

[0031] This embodiment does not limit the size of the small slag pot 3, as long as it can be locked onto the auxiliary device. For example, the auxiliary device is suitable for situations where the size of the small slag pot 3 is much smaller than the size of the large slag pot 20.

[0032] This invention does not limit the structure (shape and / or size) of the small slag pot 3, as long as it can be locked onto the auxiliary device. In this embodiment, the structure of the small slag pot 3 is the same as that of the large slag pot 20, only the size is different. The small slag pot 3 includes a small slag pot body 201, two third trunnions, and two third mounting supports. The two third trunnions are respectively mounted on both sides of the small slag pot body 201 through the two third mounting supports. However, this invention is not limited to this, and other different slag pot forms and specifications are also possible.

[0033] Specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. Unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
