A side-opening protective slag storage silo

Abstract

The present invention relates to the technical field of metallurgical equipment, and in particular to a side-opening protective slag storage bin, which is a hollow rectangular structure erected on the ground by a bracket, with a closed bin installed inside the bin, a side door installed on one side of the closed bin adjacent to the bin, and a bag opening device installed on the inner wall of the bin where the side door is located. When the bin is full of protective slag, the protective slag presses the closed bin so that the side door cannot be opened. The beneficial effects of the present invention are as follows: when the protective slag in the bin decreases and the weight of the protective slag decreases, the pry plate can be lifted, and the telescopic plate moves upward together with the pry plate, and by using different forces, the amount of protective slag remaining in the bin can be felt. Workers can place the bagged protective slag on the filter screen and drive the cutting knife to open the protective slag by turning the handle, thereby reducing the working height, eliminating the need to carry bag opening tools, and reducing the risk of foreign matter entering due to improper bag opening.

Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical equipment, and in particular to a side-opening protective slag storage bin. Background Art

[0002] Polsh powder is an important auxiliary material in continuous casting production. In an automatic slag feeding system, the molten powder waiting to be transported needs to be stored in a storage silo. Traditional storage silos are open from the top. This method has the following disadvantages: 1. Due to limited on-site space, the storage silo is generally designed to be high to accommodate more molten powder. When pouring in the molten powder, workers need to lift the bagged molten powder to a higher position or raise their feet. 2. Workers need to open the lid on the top of the storage silo to see the remaining amount of molten powder and determine whether it needs to be replenished. 3. Due to the top-opening method, the storage silo is generally not designed with a lifting ring, or the lifting ring is installed on the side, which poses a safety hazard during the overhead crane lifting process. 4. When opening the bagged molten powder, workers generally use a hot iron rod to open the bag, and the burnt residue will block the discharge port.

[0003] To this end, the present application designs a side-opening protective slag storage silo to solve the above problems. Summary of the Invention

[0004] In order to make up for the deficiencies in the prior art, the present invention provides a side-opening protective slag storage bin, which can sense the amount of residual material and is more convenient and safe.

[0005] The present invention is achieved through the following technical solutions:

[0006] A side-opening mold slag storage bin includes a storage bin, characterized in that:

[0007] The storage bin is a hollow rectangular structure erected on the ground by a bracket, and a closed bin is installed inside the storage bin. A side door is installed on one side of the storage bin adjacent to the closed bin, and a bag opening device is installed on the inner wall of the storage bin where the side door is located. When the storage bin is full of protective slag, the protective slag presses the closed bin and the side door cannot be opened.

[0008] Furthermore, in order to better implement the present invention, a lifting ring is fixedly connected to the top of the storage bin, and a slag discharge port is provided at the bottom of the storage bin.

[0009] Furthermore, in order to better realize the present invention, the bottom of the side door is hinged on the storage bin, the bottom of the side door is connected to the closed bin, and a rotatable handle is provided on the outside of the side door, and the handle is connected to the bag opening device at the inner end extending into the side door.

[0010] Furthermore, to better implement the present invention, the sealed bin includes sealed enclosures fixedly connected to two opposite inner sidewalls of the storage bin. The cross-section of the sealed enclosure is in a "U" shape. One end of a telescopic plate is hinged to the inner end of the sealed enclosure, and the other end of the telescopic plate is hinged to a pry plate. The pry plate is vertically and fixedly connected to the lower end of the side door.

[0011] Furthermore, to better implement the present invention, the bottom between the telescopic plate and the pry plate is hinged by a hinge, and a bellows protective cover is provided at the top between the telescopic plate and the pry plate.

[0012] Furthermore, to better implement the present invention, the bag-opening device includes a cutter. The cutter is a circular blade fixedly connected to a handle. The bag-opening device further includes a filter screen fixedly connected to the inner sidewall of the storage bin where the side door is located. The bagged protective slag placed through the side door is placed on the filter screen.

[0013] Furthermore, to better implement the present invention, a wire mesh is connected between the side door and the storage bin.

[0014] The beneficial effects of the present invention are as follows:

[0015] When the bin body is filled with protective slag, under the action of the gravity of the protective slag, the pry plate and the telescopic plate cannot be lifted, and the side door is in a closed state. If it is necessary to open the side door, the protective slag can be discharged through the slag discharge port.

[0016] When the protective slag in the bin body decreases and the weight of the protective slag reduces, the pry plate can be lifted, and the telescopic plate moves upward together with the pry plate. By using different forces, the amount of remaining protective slag in the bin can be felt. Workers can place the bagged protective slag on the filter screen and open the protective slag by rotating the handle to drive the cutter, which reduces the operation height, eliminates the need to carry bag-opening tools, and reduces the risk of foreign objects entering caused by improper bag opening.

[0017] When it is necessary to move the storage bin, it is hoisted through the lifting ring above. Since the lifting ring is above, the occurrence of hoisting accidents is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely intended to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0029] Figure 1-Figure 7 This is a specific embodiment of the present invention, which is a side-opening protective slag storage bin.

[0030] like Figure 1-Figure 3 As shown, the storage bin 1 is a hollow rectangular structure erected on the ground by a bracket. A closed bin 3 is installed inside the storage bin 1. A side door 2 is installed on one side of the storage bin 1 adjacent to the closed bin 3. A bag opening device 4 is installed on the inner wall of the storage bin 1 where the side door 2 is located. When the storage bin 1 is filled with protective slag, the protective slag presses the closed bin 3 so that the side door 2 cannot be opened. A lifting ring 101 is fixedly connected to the top of the storage bin 1, and a slag discharge port 102 is provided at the bottom of the storage bin 1. The bottom of the side door 2 is hinged to the storage bin 1, and the bottom of the side door 2 is connected to the closed bin 3. A rotatable handle 201 is provided on the outer side of the side door 2, and the handle 201 is connected to the bag opening device 4 at the inner end extending into the side door 2.

[0031] like Figure 4 As shown in the figure, the closed bin 3 includes a closed enclosure 303 fixedly connected to two opposite inner side walls of the storage bin 1. The cross-section of the closed enclosure 303 is in a "U" shape. One end of a telescopic plate 301 is hinged inside the closed enclosure 303, and the other end of the telescopic plate 301 is hinged to a pry plate 302. The pry plate 302 is vertically and fixedly connected to the lower end of the side door 2. The bottom between the telescopic plate 301 and the pry plate 302 is hinged by a hinge, and a bellows protective cover is provided at the top between the telescopic plate 301 and the pry plate 302. The bellows protective cover prevents the protective slag from being caught between the telescopic plate 301 and the pry plate 302. The closed enclosure 303 can also prevent the protective slag from falling below the telescopic plate 301 and the pry plate 302 to block its return.

[0032] As Figure 3 Figure 5 shown in the figure, the bag-opening device 4 includes a cutter 402. The cutter 402 is a circular blade fixedly connected to a handle 201. The bag-opening device 4 further includes a filter screen 401 fixedly connected to the inner side wall of the storage bin 1 where the side door 2 is located. The filter screen 401 holds the bagged protective slag put in from the side door 2. A wire mesh 202 is connected between the side door 2 and the storage bin 1. The wire mesh 202 prevents a small amount of protective slag from falling.

[0033] The specific implementation manner of the present invention is as follows:

[0034] When there is no protective slag or the amount of protective slag in the storage bin 1 is small, there is no downward pressure of the protective slag on the telescopic plate 301 and the pry plate 302, and the worker can easily open the side door 2. When the side door 2 is opened, the hinged part of the pry plate 302 and the telescopic plate 301翘起. Due to the closed enclosure 303, the protective slag will not fall below the pry plate 302 and the telescopic plate 301. The worker puts the bagged protective slag on the filter screen 401, and then closes the side door 2. After closing the side door 2, the pry plate 302 and the telescopic plate 301 fall downward. Then, the handle 201 is rotated, and the handle 201 drives the cutter 402 to rotate to cut open the bag of the bagged protective slag, and the protective slag enters the bin body, pressing down on the telescopic plate 301 and the pry plate 302. At this time, the side door 2 cannot be opened. The worker can judge the capacity of the protective slag inside according to the force required to open the side door 2.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
