Description

Technical Field

[0001] The present invention relates to the field of metallurgical energy-saving and environmentally friendly equipment, and in particular to a heat-insulating device for container packaging and a transfer system. Background Art

[0002] Before producing finished products, domestic steel and metallurgical companies must produce liquid steel / iron through a chemical smelting reduction process. This molten steel / iron requires specialized container bags during transportation. However, because these bags are open, not only does the molten steel / iron come into contact with air during transportation, generating convection and producing a lot of smoke and dust, which is also contaminated with harmful gases, endangering human health and environmental protection. Furthermore, the open bags cause heat loss from the molten steel / iron, increasing heat demand and prolonging smelting time during subsequent smelting, hindering energy efficiency. Therefore, it is essential to equip the container bags with insulation devices to reduce convection between the molten steel / iron and air while also achieving energy conservation and heat preservation.

[0003] In addition, during the steel / iron smelting process, the insulation device and the container package are often required to complete the pouring of the steel / iron at the same time, which requires the insulation device to be opened and closed frequently. This requires a safe and effective connection mechanism to be provided between the insulation device and the container package to ensure that the insulation device does not fall off the container package during the pouring of the steel / iron.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] One of the purposes of the present invention is to provide a heat preservation device for a container package to reduce convection between steel / molten iron and air in the container package and heat loss of the steel / molten iron.

[0049] Another object of the present invention is to provide a transport system having the above-mentioned container packaging heat preservation device.

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Example 1

[0052] like Figure 1 As shown, this embodiment provides an insulation device 100 for a container bag, including an insulation cover 101 and a safety lock ear 102. The insulation cover 101 is used to cover the opening of the container bag 200, which can reduce the contact between external air and the liquid in the container bag 200; the safety lock ear 102 is arranged on one side of the insulation cover 101, and a U-shaped groove 103 is provided on the safety lock ear 102. The U-shaped groove 103 is used to be hung with a connecting shaft 201 provided at the opening of the container bag 200, and the insulation cover 101 can rotate around the connecting shaft 201 to realize the opening and closing of the insulation cover 101.

[0053] In this embodiment, the two side walls of the U-shaped groove 103 are as follows Figure 1 and 2 The first side wall 104 and the second side wall 105 are arranged at an angle to the vertical line 111 of the thermal insulation cover plate 101 along the thickness direction. Figure 2As shown, the bottom ends of the first side wall 104 and the second side wall 105 are inclined toward the vertical line 111, so that the U-shaped groove 103 is inclined from the bottom of the groove to the groove mouth toward the center position of the insulation cover 101, that is, the U-shaped groove 103 is inclined from right to left as a whole. The connecting shaft 201 is arranged between the first side wall 104 and the second side wall 105. In order to prevent the connecting shaft 201 from easily sliding out of the notch of the U-shaped groove 103 (the notch is located between the bottom end of the first side wall 104 and the bottom end of the second side wall 105), the notch can be appropriately shrunk. For example, the inclination angle of the first side wall 104 can be set to be smaller than the inclination angle of the second side wall 105 to achieve the effect of shrinking the notch. As a preferred method, the side wall of the U-shaped groove 103 close to the center of the insulation cover 101, that is, the first side wall 104, is set to an angle of 3° to 9° with the vertical line 111, while the side wall of the U-shaped groove 103 away from the center of the insulation cover 101, that is, the second side wall 105, is set to an angle of 4° to 10° with the vertical line 111.

[0054] In this embodiment, the heat-insulating cover plate 101 includes a metal outer cover and a heat-insulating layer. A safety lock ear 102 is fixedly installed on the right side of the metal outer cover and can be hung on the connecting shaft 201 through the U-shaped groove 103 of the safety lock ear 102. Figure 1 As shown, the metal cover is on top and the insulation layer is on the bottom. Due to limited space in the smelting workshop, to ensure that the normal transportation of the container package 200 is not affected, the total thickness of the insulation layer and the metal cover is preferably no more than 350 mm. In this way, after the container package insulation device 100 is covered at the opening of the container package 200, the container package 200 will not be significantly increased in height, which is conducive to the normal operation of the container package 200. Preferably, the metal cover is made of spliced ​​steel profiles; the insulation layer can be made of glass fiber, asbestos, rock wool, aerogel felt, vacuum board, casting material, etc.

[0055] In this embodiment, in order to further prevent the entire container bag heat preservation device 100 from falling off the connecting shaft 201 when the container bag 200 is poured with liquid, a safety block 106 is provided at the notch of the U-shaped groove 103. Figure 1 and 2 As shown, the bottom end of the first side wall 104 is shorter than the bottom end of the second side wall 105. A safety block 106 is provided at the bottom end of the second side wall 105. The safety block 106 protrudes toward the first side wall 104, further reducing the notch. Figure 6In the tilted position shown, the insulation cover 101 automatically opens under the action of gravity. The U-shaped groove 103 is tilted inward and has a narrowing tendency, which acts as a decelerator. When the connecting shaft 201 of the container bag 200 contacts the safety stopper 106 on the safety lock ear 102, it is locked, and the connecting shaft 201 will not slip out of the notch of the U-shaped groove 103, thereby effectively preventing the insulation cover 101 from falling during the pouring process of the container bag 200. Preferably, the height difference between the bottom end of the first side wall 104 and the bottom end of the second side wall 105 is 70mm to 150mm.

[0056] At the same time, this embodiment also proposes a transfer system, including a container bag 200, a container bag transfer assembly, a switch mechanism 300 and the above container bag heat preservation device 100, the container bag heat preservation device 100 is hung on the connecting shaft 201 through the safety lock ear 102, the container bag 200 is set on the container bag transfer assembly, and the container bag transfer assembly is used to transport the container bag 200 in a straight line to form a liquid conveying line; the switch mechanism 300 is set above the liquid conveying line, and the container bag 200 will pass through the switch mechanism 300 during the conveying process. Figures 3 to 5As shown, a first oblique wedge arm 301 is provided at the bottom of the switch mechanism 300. The first oblique wedge arm 301 is provided in the opposite direction of the conveying direction of the container bag 200 when it is unloaded. The edge of the thermal insulation cover 101 is provided with an insertion hole for the first oblique wedge arm 301 to pass through. When the unloaded container bag 200 passes the first oblique wedge arm 301, the first oblique wedge arm 301 is inserted into the insertion hole on the thermal insulation cover 101. As the container bag 200 continues to operate, the container bag insulation device 100 is removed from the container bag 200 to open the container bag 200 and fill the container bag 200 with liquid. The aforementioned removal of the heat-insulating device 100 for a container bag from the container bag 200 refers to disengaging the connecting shaft 201 from the notch of the U-shaped groove 103, so that the heat-insulating device 100 for a container bag is completely separated from the container bag 200. The aforementioned "empty" does not completely mean that the container bag 200 does not contain any objects. Here, "empty" refers to a state in which the container bag 200 needs to be loaded with liquid. In this state, the container bag 200 can be completely empty or can contain some liquid but not be full. The container bag 200 filled with liquid is transported in the opposite direction along the liquid conveying line and passes through the switch mechanism 300 again. With the help of inertia in the conveying state, the container bag 200 touches and hits the safety stopper 106 through the connecting shaft 201. Since the second side wall 105 where the safety stopper 106 is set is longer than the first side wall 104, the connecting shaft 201 will slide into the U-shaped groove 103. As the container bag 200 continues to run, the connecting shaft will pull the container bag insulation device 100 off the first wedge arm 301. At this time, the container bag insulation device 100 restores the hinged state with the container bag 200 and covers the opening of the container bag 200 under the action of gravity, and is transported together with the container bag 200. Finally, after the liquid is poured, it returns with the container bag 200 again, repeating the above-mentioned process of the container bag insulation device 100 detaching from the container bag 200 and the container bag insulation device 100 reconnecting with the container bag 200.

[0057] In this embodiment, the above-mentioned jack is opened on the edge of the metal cover, specifically a strip-shaped jack, and is arranged parallel to the above-mentioned liquid delivery line. Figure 1 、 4 As shown in FIG5 , a lifting shaft 107 is rotatably mounted at the center of the strip-shaped socket. The lifting shaft 107 separates the strip-shaped socket into a first socket area and a second socket area along the conveying direction of the liquid conveying line. Figure 4 As shown, the first socket area is located on the left side of the lifting shaft 107, the second socket area is located on the right side of the lifting shaft 107, and the connecting shaft 201 is also located on the right side of the second socket area. In this way, the second socket area is located between the connecting shaft 201 and the first socket area. The lifting shaft 107 is actually located above the strip-shaped socket. The first and second socket areas are not completely separated by the lifting shaft 107, but only serve as a boundary. The first and second socket areas are still connected to each other, as shown in FIG. Figure 4 From the perspective shown, the first angled wedge arm 301 can be inserted from left to right into the strip-shaped insertion hole from the first insertion hole area on the left side of the lifting shaft 107. After rotating the first angled wedge arm 301 180 degrees, it can also be inserted from right to left into the strip-shaped insertion hole from the second insertion hole area on the right side of the lifting shaft 107, thereby enabling the switch mechanism 300 to bidirectionally insert the container bag heat preservation device 100. The "bidirectional insertion function" is specifically determined by the transport direction of the empty container bag 200. Depending on the transport direction of the empty container bag 200, the switch mechanism 300 has a first setting mode and a second setting mode, where:

[0058] In the first setting mode, the switch mechanism 300 is fixed, or even if the switch mechanism 300 is connected to other components, it remains stationary during the entire process, such as Figure 4 and 5 As shown, when the container bag 200 is empty, the conveying direction is set from right to left. At this time, the safety lock ear 102 is also located on the right side of the heat preservation device for the container bag 100, the first inclined wedge arm 301 is tilted to the right, and the bottom end of the first inclined wedge arm 301 points to the connecting shaft 201. First, the container bag 200, with the heat-insulating device 100 attached, is transported from right to left to load liquid. As it passes through the switch mechanism 300, the first angled wedge arm 301 inserts into the first insertion hole, driving the lifting shaft 107 to rotate counterclockwise. The lifting shaft 107 rolls into contact with the first angled wedge arm 301, guiding and limiting the first angled wedge arm 301. The container bag 200 continues to be transported from right to left, and the heat-insulating device 100 is removed from the connecting shaft 201. After the container bag 200 is loaded with liquid, it is transported from left to right. As it passes through the switch mechanism 300 again, the heat-insulating device 100 is removed from the first angled wedge arm 301, reconnecting it to the heat-insulating device 100. This configuration can be referred to as the "positive operation of the switch mechanism 300 and the heat-insulating device 100."

[0059] Accordingly, in the second setting mode, the switch mechanism 300 is arranged above the liquid delivery line through the lifting mechanism, such as Figure 7As shown, the conveying direction of the container bag 200 when empty is set to be from left to right. At this time, the safety lock ear 102 is also located on the right side of the container bag heat preservation device 100, but the first inclined wedge arm 301 is tilted to the left, and the bottom end of the first inclined wedge arm 301 is away from the connecting shaft 201. First, the container bag 200 with the container bag heat preservation device 100 is transported from left to right to load liquid. When passing through the switch mechanism 300, the first inclined wedge arm 301 is inserted into the second insertion hole area and drives the lifting shaft 107 to rotate clockwise. The lifting shaft 107 rolls in contact with the first inclined wedge arm 301, guiding and limiting the first inclined wedge arm 301. The container bag 200 continues to be transported from left to right. At the same time, the lifting mechanism lifts the switch mechanism 300 and flips the first inclined wedge arm 301 upward counterclockwise. Under the lifting and flipping effects of the lifting mechanism and the transportation power of the container bag 200, the lifting and flipping effects of the lifting mechanism and the transportation power of the container bag 200 are greatly improved. Under this action, the heat-insulating device 100 for container bags is removed from the connecting shaft 201. After the container bag 200 is filled with liquid, it is transported in the reverse direction from right to left. When it passes the switch mechanism 300 again, it needs to stop moving briefly. The lifting mechanism lowers the switch mechanism 300 and flips the first inclined wedge arm 301 clockwise downward, so that the connecting shaft 201 is engaged with the U-shaped groove 103 on the heat-insulating device 100 for container bags. The container bag 200 then continues to be transported from right to left, removing the heat-insulating device 100 from the first inclined wedge arm 301 and restoring its connection with the heat-insulating device 100. This setting mode can be referred to as the "reverse use of the switch mechanism 300 and the heat-insulating device 100 for container bags" mode.

[0060] In this embodiment, the lifting shaft 107 is mounted on the metal outer cover via a shaft seat, and the lifting shaft 107 is rotatably connected to the shaft seat via a bearing. As a preferred embodiment, the shaft seat is welded to the metal outer cover.

[0061] In this embodiment, the first inclined wedge arm 301 is preferably an inclined straight wedge arm, and its inclination angle is preferably 15° to 30°, which plays a role of lifting and climbing.

[0062] In this embodiment, a safety guide assembly is provided on the side edge of the thermal insulation cover 101 opposite to the safety lock ear 102, i.e., on the left side of the thermal insulation cover 101. The safety guide assembly further ensures the reliable fit between the thermal insulation cover 101 and the switch mechanism 300. The safety guide assembly includes a support plate 108, a locking shaft 109, and a parking shaft 110. Two sets of support plates 108 are arranged in parallel and spaced apart. Both sets of support plates 108 are disposed on the left edge of the thermal insulation cover 101. The locking shaft 109 is rotatably mounted between the two sets of support plates 108 and can rotate freely. The parking shaft 110 is fixedly disposed between the two sets of support plates 108 and cannot rotate. The locking shaft 109 and the parking shaft 110 can be arranged parallel to the lifting shaft 107 or not. The locking shaft 109 is higher than the parking shaft 110, and the parking shaft 110 is located between the locking shaft 109 and the lifting shaft 107. Correspondingly, a second oblique wedge arm 302 is provided at the bottom of the switch mechanism 300, and the inclination direction of the second oblique wedge arm 302 is consistent with the inclination direction of the first oblique wedge arm 301; a groove socket 303 is provided at the top of the second oblique wedge arm 302 for accommodating the locking shaft 109 and the parking shaft 110. During operation, the process of the locking shaft 109 and the parking shaft 110 climbing and rising along the second oblique wedge arm 302 into the groove socket 303 is synchronized with the process of the first oblique wedge arm 301 inserting into the bar socket. When the heat preservation device 100 for container bag is removed from the first inclined wedge arm 301 and the second inclined wedge arm 302, the hanging relationship between the connecting shaft 201 and the U-shaped groove 103 and the mobility of the container bag are utilized to apply a pulling force to the heat preservation device 100 for container bag. The pulling force is greater than the friction force between the parking shaft 110 and the inner wall of the groove 303, thereby forcibly pulling the locking shaft 109 and the parking shaft 110 out of the groove 303, thereby realizing the separation between the heat preservation device 100 for container bag and the switch mechanism 300.

[0063] In this embodiment, the second inclined wedge arm 302 is specifically a grooved socket type, and its inclination angle is preferably 25° to 38°; the grooved socket 303 on the second inclined wedge arm 302 serves to safely store the parking shaft 110 and the locking shaft 109.

[0064] In this embodiment, the safety guide assembly is welded to the metal outer cover via the support plate 108. The locking shaft 109 is rotatably connected to the support plates 108 on both sides via bearings and is capable of rolling contact with the climbing slope of the second wedge arm 302. The parking shaft 110 is fixedly arranged between the support plates 108 on both sides. As a preferred embodiment, the parking shaft 110 and the locking shaft 109 are highly intersected and do not overlap, that is, the parking shaft 110 and the locking shaft 109 are perpendicular to each other in the direction of the vertical line 111 (i.e., Figure 1 The spacing in the vertical direction shown is 40mm to 80mm, and the horizontal spacing between the parking shaft 110 and the locking shaft 109, that is, Figure 1The distance in the left-right direction shown is 90 mm to 120 mm.

[0065] In this embodiment, the insulation cover 101 is thicker due to the installation of the above-mentioned safety guide assembly, lifting shaft 107 and safety lock ear 102. Preferably, the overall thickness of the insulation cover 101 after the installation of the above-mentioned safety guide assembly, lifting shaft 107 and safety lock ear 102 does not exceed 500 mm, that is, the thickness from the container bag mouth to the highest point of the insulation cover 101 does not exceed 500 mm, so as to ensure the normal operation and use of the container bag 200.

[0066] Preferably, two sets of strip-shaped sockets and the aforementioned safety guide assembly are provided, symmetrically distributed on the front and rear sides of the insulation cover 101. Two corresponding lifting shafts 107 are provided, one for each set of strip-shaped sockets. Accordingly, the switch mechanism 200 is equipped with two sets of first angled wedge arms 301 and two sets of second angled wedge arms 302, for a total of four angled wedge-shaped lifting arms.

[0067] The container bag insulation device proposed in this technical solution is used to cover the opening of the container bag, which can reduce the contact between external air and the liquid in the container bag, thereby reducing the convection between the steel / molten iron in the container bag and the air, avoiding the generation of smoke and harmful gases, and improving the safety of the steel / molten iron during transportation. At the same time, the container bag insulation device also has a heat preservation effect, preventing the loss of heat from the steel / molten iron in the container bag, ensuring that the steel / molten iron entering the subsequent smelting process has a high self-contained heat. This can reduce energy consumption during the smelting process and achieve energy conservation and environmental protection. The container bag insulation device has a reduced thickness and increased flexibility of use, making it suitable for a variety of occasions.

[0068] The transfer system proposed in this technical solution includes a container bag, a container bag transfer component, a switching mechanism and the above-mentioned container bag insulation device. The container bag transfer component provides power for the operation of the container bag. The switching mechanism is a dedicated switch for the container bag insulation device. The connection structure between the container bag insulation device and the container bag and the conveying characteristics of the container bag are cleverly utilized to achieve the connection and disconnection between the container bag insulation device and the container bag. When the container bag insulation device is disconnected from the container bag, it is convenient to fill the container bag with steel / molten iron. After the steel / molten iron is filled, the container bag insulation device is connected to the container bag again to cover the opening of the container bag, reduce the convection between the steel / molten iron and the air in the container bag, and at the same time achieve the steel / molten iron insulation effect.

[0069] In this technical solution, a safety block is provided on the safety lock ear on the heat-insulating device for the container bag, which can prevent the heat-insulating cover from falling off the container bag during the process of pouring liquid from the container bag.

[0070] In the present technical solution, the strip-shaped insertion hole provided on the edge of the metal outer cover is divided into a first insertion hole area and a second insertion hole area by a lifting shaft. According to the different conveying directions of the container bag when it is empty, the first inclined wedge insertion arm can cleverly avoid obstacles and choose to insert the strip-shaped insertion hole from the first insertion hole area or the second insertion hole area, thereby realizing the bidirectional insertion of the switch mechanism into the heat preservation device for the container bag and realizing the opening / closing of the heat preservation device for the container bag in two directions. It is convenient and flexible to use and can meet different container bag conveying requirements.
