Currently, materials are generally mixed using mixing equipment. For some materials, the incoming material is usually in bags, which requires manual opening of the ton bags and pouring of the material into the mixing equipment, resulting in low operating efficiency. Utility Model Content

[0003] The technical problem this application aims to solve is that existing mixing equipment requires manual opening of the ton bags for material feeding, resulting in low operating efficiency. To solve this technical problem, this application provides a mixing equipment and metallurgical system that eliminates the need for manual opening of the ton bags and offers higher operating efficiency.

[0010] Using the aforementioned mixing equipment, the conveying mechanism transports the ton bags to the hopper, and the bag cutter ruptures the ton bags, allowing the material inside to fall into the hopper and then into the mixing drum. The mixing drum rotates, mixing the various materials inside. Because the bag cutter can rupture the ton bags transported to the hopper by the conveying mechanism, allowing the material inside to fall into the hopper, there is no need for manual opening of the ton bags and pouring of the material into the hopper, improving operational efficiency. Furthermore, the conveying and bag-cutting processes are all contactless, enhancing operational safety.

[0015] Furthermore, the conveying mechanism includes a translation drive, a lifting drive, and a gripping component. The translation drive is disposed on the frame and connected to the lifting drive to drive the lifting drive to move in the horizontal direction. The lifting drive is connected to the gripping component to drive the gripping component to move in the vertical direction. The gripping component is capable of gripping and releasing the ton bag.

[0016] Furthermore, the mixing equipment also includes a drive mechanism, which is disposed on the frame and connected to the mixing cylinder to drive the mixing cylinder to rotate.

[0017] Furthermore, the driving mechanism includes a rotational driving component and a driving gear. The rotational driving component is disposed on the frame and connected to the driving gear. A driven gear is provided on the outer side of the mixing cylinder, and the driving gear meshes with the driven gear shown.

[0018] Furthermore, the mixing equipment also includes a tapping mechanism, which includes a tapping drive and a tapping component. The tapping drive is disposed on the frame and connected to the tapping component to drive the tapping component to rotate and tap the outside of the mixing cylinder.

[0019] Furthermore, the mixing equipment also includes a dust removal mechanism, which is connected to the silo and the mixing cylinder.

[0020] Furthermore, the dust removal mechanism includes a dust collector, an induced draft fan, and a dust removal pipeline. The dust collector and the induced draft fan are connected to each other, and the dust collector is connected to the silo and the mixing cylinder through the dust removal pipeline.

[0038] On the one hand, this application provides a mixing device that can mix several materials to facilitate the subsequent melting of the mixed materials.

[0039] like Figure 1 and Figure 2 As shown, in one embodiment, the mixing device 100 includes a frame 110 and a conveying mechanism 120, a hopper 131, and a mixing cylinder 140 disposed on the frame 110. The hopper 131 communicates with the interior of the mixing cylinder 140, and the mixing cylinder 140 is rotatably disposed.

[0040] The conveying mechanism 120 can transport the ton bag 200 to the silo 131. The ton bag 200 contains materials, which fall into the silo 131 and are then fed into the mixing cylinder 140, which is connected to the silo 131. Through multiple transports by the conveying mechanism 120, various materials can be transported and fed into the mixing cylinder 140. The mixing cylinder 140 is rotatably arranged, so that the various materials inside the mixing cylinder 140 are tumbled and mixed during the rotation process.

[0041] Furthermore, the mixing equipment 100 includes a bag cutter 132, which is disposed in the hopper 131 and is used to cut open the ton bags 200 transported to the hopper 131 by the conveying mechanism 120, so that the material inside the ton bags 200 falls into the hopper 131 and enters the mixing cylinder 140 through the hopper 131. Optionally, the bag cutter 132 may be a blade, with the blade facing the ton bags 200 transported to the hopper 131 by the conveying mechanism 120, so as to contact and cut the ton bags 200.

[0042] Using the aforementioned mixing equipment 100, the conveying mechanism 120 transports the ton bag 200 to the silo 131, and the bag cutter 132 cuts open the ton bag 200, allowing the material inside to fall into the silo 131 and then into the mixing cylinder 140. The mixing cylinder 140 is rotated to mix the various materials inside. Because the bag cutter 132 can cut open the ton bag 200 transported to the silo 131 by the conveying mechanism 120, allowing the material inside to fall into the silo 131, there is no need for manual opening of the ton bag 200 and pouring of the material into the silo 131, improving operational efficiency. Furthermore, the handling and bag cutting processes are all contactless, improving operational safety.

[0043] In one embodiment, the conveying mechanism 120 includes a translation drive 121, a lifting drive 122, and a gripping member 123. The translation drive 121 is disposed on the frame 110 and connected to the lifting drive 122 to drive the lifting drive 122 to move horizontally; the lifting drive 122 is connected to the gripping member 123 to drive the gripping member 123 to move vertically; the gripping member 123 is used to grip and release the ton bag 200.

[0044] It should be noted that in this embodiment, the material in the hopper 131 is conveyed to the mixing cylinder 140 under the action of gravity, so the horizontal height of the hopper 131 is higher than the height of the feeding end of the mixing cylinder 140. After the gripper 123 grips the ton bag 200, the lifting drive 122 first lifts the ton bag 200 to a height that allows it to enter the hopper 131, and then the translation drive 121 drives the ton bag 200 to move towards the hopper 131, so that the ton bag 200 is torn by the bag cutter 132 after entering the hopper 131. Similarly, after the material in the ton bag 200 is released, the translation drive 121 and the lifting drive 122 drive the gripper 123 back to the initial position, and then the gripper 123 releases the ton bag 200, and then another ton bag 200 can be transported. The translation drive 121 and the lifting drive 122 can be linear modules or other drive structures, and the gripper 123 can be a claw, a hook or other structure capable of gripping the ton bag 200, without any restrictions.

[0045] In one embodiment, the bottom of the hopper 131 is provided with a discharge port, and the mixing cylinder 140 is provided with a feed port. The mixing device 100 also includes a chute 133, one end of which is connected to the discharge port, and the other end extends into the mixing cylinder 140 through the feed port, so that the material in the hopper 131 is transported into the mixing cylinder 140 under the action of gravity.

[0046] In one embodiment, the mixing cylinder 140 is rotatable about its central axis and also has a discharge port. The inlet and outlet are located at opposite ends of the mixing cylinder 140. Specifically, the inlet and outlet are coaxial, and their centers coincide with the central axis of the mixing cylinder 140. Thus, the inlet and outlet will not shift during the rotation of the mixing cylinder 140, facilitating the input and output of materials. Taking material input as an example, the chute 133 extends into the mixing cylinder 140 through the inlet. Since the inlet will not shift during the rotation of the mixing cylinder 140, collisions between the chute 133 and the edge of the inlet can be avoided.

[0047] Furthermore, the mixing cylinder 140 is also equipped with spiral blades, and the mixing cylinder 140 can rotate in both directions. During the forward rotation of the mixing cylinder 140, the mixed materials can be tumbled inside the mixing cylinder 140; during the reverse rotation of the mixing cylinder 140, the materials inside the mixing cylinder 140 can be conveyed towards the discharge port under the action of the spiral blades.

[0048] It should be noted that the spiral blades are disposed on the inner wall of the mixing cylinder 140, forming a spiral channel on the inner wall. One end of the spiral channel is connected to the discharge port, thereby guiding the material along the spiral channel and discharging it from the discharge port when the mixing cylinder 140 rotates in reverse. At the same time, the other end of the spiral channel is not connected to the inlet, so when the mixing cylinder 140 rotates forward, the material will not be discharged from the inlet, but will instead tumble and mix inside the mixing cylinder 140.

[0049] In one embodiment, the mixing device 100 further includes a drive mechanism 150, which is disposed on the frame 110 and connected to the mixing cylinder 140 to drive the mixing cylinder 140 to rotate. Therefore, in this embodiment, the driving mechanism 150 can drive the mixing cylinder 140 to rotate in both directions.

[0050] Furthermore, the drive mechanism 150 includes a rotation drive component 151 and a drive gear 152. The rotation drive component 151 is mounted on the frame 110 and connected to the drive gear 152. A driven gear 141 is provided on the outer side of the mixing cylinder 140. The drive gear 152 meshes with the driven gear 141, thereby connecting to the drive mechanism 150 and driving the mixing cylinder 140 to rotate through the drive mechanism 150. Specifically, the rotation drive component 151 is a motor. The rotation drive component 151 can be connected to the drive gear 152 through a reducer. The drive gear 152 meshes with the annular driven gear 141.

[0051] In one embodiment, the mixing equipment 100 further includes a tapping mechanism 160, which is disposed on the frame 110 and is used to tap the outside of the mixing cylinder 140 to prevent the material inside the mixing cylinder 140 from adhering to the inner wall of the mixing cylinder 140.

[0052] Furthermore, the tapping mechanism 160 includes a tapping drive 161 and a tapping element 162. The tapping drive 161 is disposed on the frame 110 and connected to the tapping element 162 to drive the tapping element 162 to rotate and tap the outer side of the mixing cylinder 140. It should be noted that the tapping drive 161 can either drive the tapping element 162 to swing, during which the tapping element 162 taps the outer side of the mixing cylinder 140; or it can drive the tapping element 162 to rotate continuously in a rotation direction, in which case the tapping element 162 can be bent, that is, when it contacts the outer side of the mixing cylinder 140, it taps the mixing cylinder 140, and then the tapping element 162 continues to rotate and bend, tapping the mixing cylinder 140 again after one rotation. If the tapping element 162 can be bent, it can be made of a flexible material, which is not limited here.

[0053] In practical applications, the tapping mechanism 160 also includes a connecting rod 163 and multiple tapping components 162; the connecting rod 163 extends along the axial direction of the mixing cylinder 140, the tapping drive component 161 is connected to the connecting rod 163, and multiple tapping components 162 are spaced apart on the connecting rod 163 along the length direction of the connecting rod 163.

[0054] In one embodiment, the mixing device 100 further includes a dust removal mechanism 170, which is connected to the hopper 131 and the mixing cylinder 140 to collect escaped material dust. Specifically, the dust removal mechanism 170 is connected to the outlet of the mixing cylinder 140 to collect escaped dust when the material is discharged from the mixing cylinder 140. In addition, it can be determined that the dust removal mechanism 170 typically uses negative pressure adsorption to collect dust. The dust removal mechanism 170 can form a certain negative pressure inside the mixing cylinder 140, thereby preventing dust from escaping from the inlet to a certain extent.

[0055] In one embodiment, the dust removal mechanism 170 includes a dust collector 171, an induced draft fan 172, and a dust removal duct 173. The dust collector 171 is arranged sequentially with the induced draft fan 172, which guides dust into the dust collector 171 and is located downstream of the dust collector 171. The dust collector 171 is connected to the hopper 131 and the mixing cylinder 140 via the dust removal duct 173. That is, the induced draft fan 172 guides the dust in the hopper 131 and the mixing cylinder 140 into the dust collector 171 through the dust removal duct 173, and then the dust collector 171 collects the dust, while the gas is discharged through the induced draft fan 172.

[0056] Furthermore, the dust removal mechanism 170 also includes a dust removal hood 174, which is disposed at the discharge port of the mixing cylinder 140. One end of the dust removal pipe 173 is connected to the dust removal hood 174, thereby collecting the dust at the discharge port of the mixing cylinder 140. Optionally, the dust collector 171 can be a bag filter 171, an electrostatic precipitator 171, or a combination of a cyclone dust collector 171 and a bag filter 171; no limitation is made here.

[0057] To facilitate understanding of the technical solution of this application, this document combines... Figure 1 The process flow of the mixing equipment 100 in the above embodiments is described as follows:

[0058] The ton bag 200 is transported to a preset position by a trolley. The gripper 123 grips the ton bag 200, and then the lifting drive 122 lifts the ton bag 200 to a height corresponding to the hopper 131. The translation drive 121 moves the ton bag 200 horizontally into the hopper 131, and the bag cutter 132 cuts the ton bag 200 entering the hopper 131, allowing the material to fall into the hopper 131 and then into the mixing cylinder 140 via the chute 133. Next, the translation drive 121 and the lifting drive 122 drive the gripper 123 back to its initial position, and the gripper 123 releases the ton bag 200. The above steps are repeated to add multiple materials into the mixing cylinder 140.

[0059] The drive mechanism 150 drives the mixing cylinder 140 to rotate clockwise, causing the various materials inside the mixing cylinder 140 to tumble and mix. After mixing is complete, the drive mechanism 150 drives the mixing cylinder 140 to rotate counterclockwise, so that the materials are output from the discharge port. During the rotation of the mixing cylinder 140, the tapping drive 161 drives the tapping component 162 to tap the outside of the mixing cylinder 140. In addition, throughout the process, the dust collection mechanism 170 can collect the scattered dust.

[0060] It should be noted that the mixing equipment 100 can also be equipped with a control mechanism, which is electrically connected to the conveying mechanism 120, the drive mechanism 150, the dust removal mechanism 170, and the tapping mechanism 160 to realize the automated operation of the mixing equipment 100. In addition, a weighing mechanism and a vision inspection mechanism can be installed at the conveying mechanism 120. The weighing mechanism can weigh the materials to obtain the quantity of the corresponding materials and improve the accuracy of the material mixing ratio; the vision inspection mechanism can detect the position of the ton bag 200, which facilitates the gripper 123 to grip the ton bag 200.

[0061] On the other hand, this application also provides a metallurgical system, which includes the mixing device 100 in the above embodiments. It can also be determined that the metallurgical system further includes a metallurgical furnace located downstream of the mixing device 100, for smelting the mixed materials.

[0062] In summary, the mixing equipment 100 and metallurgical system provided in this application have at least the following advantages:

[0063] 1. The bag cutter 132 can cut the ton bag 200 that is transported to the hopper 131 by the conveying mechanism 120, so that the material inside the ton bag 200 falls into the hopper 131, realizing the addition of material without the need for manual opening of the ton bag 200 and adding material, thus improving the efficiency and safety of operation.

[0064] 2. The dust removal mechanism 170 can collect the dust emitted from the hopper 131 and the mixing cylinder 140, reducing dust pollution to the environment;

[0065] 3. The tapping mechanism 160 can prevent materials from adhering to the inner wall of the mixing cylinder 140 and increase the amount of material discharged from the outlet.

[0066] 4. The mixing cylinder 140 is equipped with spiral blades. In conjunction with the forward and reverse rotation of the mixing cylinder 140, the material is tumbled and mixed, and the material in the mixing cylinder 140 can be output through the discharge port.
