The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0026] See also Figures 1 to 8In one embodiment, an integrated feeding system for dry and wet mineral materials includes a conveyor belt 7, a rotating shaft 72, and a raw material bin 3. The conveyor belt 7 is sleeved on the rotating shaft 72, and the raw material bin 3 is arranged on one side of the conveyor belt 7. It also includes a frame 4, a conveyor frame 71, a sidewall conveyor 2, and a screen drum 1. The screen drum 1 is installed at the end of the conveyor belt 7 away from the raw material bin 3, and the sidewall conveyor 2 is installed on the side of the conveyor belt 7 away from the raw material bin 3. The conveyor frame 71 is slidably installed on the frame 4, and a plurality of rotating shafts 72 are rotatably installed on the conveyor frame 71. The plurality of rotating shafts 72 are transmission-connected, and the conveyor frame 71 is slidably installed on the conveyor frame 4. A second driving member 15 is fixedly mounted on the frame 4, one end of the second driving member 15 is connected to the output shaft 14, a connecting rod 11 is mounted on the end of the output shaft 14 away from the second driving member 15, a first stop column 12 is fixedly mounted on the connecting rod 11, a first slot plate 10 is fixedly mounted on the conveying frame 71, the first stop column 12 is located in the slot of the first slot plate 10, a sliding column 8 is slidably mounted on the frame 4, the sliding column 8 is connected to the locking assembly 9, and the locking assembly 9 is used to drive the sliding column 8 to extend into the slot of the first slot plate 10 through the movement of the conveying frame 71.

[0027] In this embodiment, a fixed block 41 is fixedly installed on the frame 4, and a sliding column 8 is slidably installed on the fixed block 41. There is a certain gap between the bottom of the raw material bin 3 and the conveyor belt 7, and the conveying end point of the conveyor belt 7 extends into the screen drum 1. The side guard conveyor 2 is located below the conveyor belt 7, and one of the rotating shafts 72 is connected to the first driving member 73, and the rotating shaft 72 is driven to rotate by the first driving member 73. A plurality of the rotating shafts 72 are connected to each other through a transmission member 76, and the transmission member 76 can be a belt or a chain. The surface of the frame 4 is hollowed out, and a transverse reinforcing rib 42 is fixedly installed on the surface of the frame 4, and a second driving member 15 is fixedly installed on the transverse reinforcing rib 42. The first driving member 73 and the second driving member 15 can be a servo motor, a magnetic flux motor, etc.

[0028] In this embodiment, when feeding wet mineral materials, the wet mineral materials are first put into the raw material bin 3, and then discharged to the conveyor belt 7 through the raw material bin 3. The conveyor belt 7 is driven by the first driving member 73 to rotate, so that the materials are put into the screen drum 1, so as to carry out subsequent material screening and impurity removal, rubbing and selection operations, mud removal, wet magnetic separation, dehydration and drying, and titanium dry magnetic separation. When it is necessary to feed dry mineral materials, the dry mineral materials are put into the raw material bin 3, and then the second driving member 15 is driven. The second driving member 15 drives the connecting rod 11 to rotate, and the connecting rod 11 rotates while pulling the first notch plate 10 to move linearly. , that is, driving the conveying frame 71 to move in a straight line until one end of the conveying frame 71 moves to the top of the sidewall conveyor 2. When the first notch plate 10 moves to the farthest point, the locking assembly 9 drives the sliding column 8 to move into the notch of the first notch plate 10, thereby locking the position of the conveying frame 71, thereby avoiding the position deviation caused by factors such as vibration during the transmission process, thereby causing the material to fall. The dry mineral material is transported to the sidewall conveyor 2 through the conveyor belt 7, and the position of the conveying frame 71 is adjusted according to the different materials. When the material is suitable for the pulping feeding method, the conveying frame 71 moves forward and extends into the screen drum 1 for pulping. When the material is suitable for the dry ore feeding method, the conveying frame 71 retracts and transports the material to the sidewall conveyor 2, and the sidewall conveyor 2 climbs to transport the material to the next process.

[0029] The feed position is switched by moving the conveyor frame 71, so that the dry mineral material and the wet mineral material can share the same feed system to adapt to different feed requirements and process routes. Compared with the traditional single feed system, this feed system can improve the efficiency of mineral processing, save processes, increase equipment capacity, shorten the production cycle, and reduce energy consumption. For the processing of titanium ore that does not require wet magnetic separation, the feed system can be switched from the original fixed process route (raw ore → pulping and impurity removal → scrubbing → primary desludging → secondary desludging → one-stage wet magnetic separation → dehydration → drying → titanium dry magnetic separation) to a more suitable process route (raw ore → drying → titanium dry magnetic separation), which greatly reduces the intermediate processes.

[0030] See also Figure 2 , Figure 3 In one embodiment, the locking assembly 9 includes a first wedge block 91, a second wedge block 92, and a spring 93. The first wedge block 91 is fixedly mounted on the conveying frame 71, and the second wedge block 92 is fixedly mounted on one end of the sliding column 8. A spring 93 is installed between the second wedge block 92 and the frame 4.

[0031] In this embodiment, when switching between dry ore and wet ore feeding, the connecting rod 11 is driven to rotate by the second driving member 15. While the connecting rod 11 rotates, the first slot plate 10 is pulled to move linearly, that is, the conveying frame 71 is driven to move linearly. When the conveying frame 71 is about to move to the specified position, the first wedge block 91 contacts the second wedge block 92. In the process of continuing to move, the first wedge block 91 pushes the second wedge block 92 to descend. When the first wedge block 91 contacts the horizontal surface of the second wedge block 92, the sliding column 8 connected to the second wedge block 92 is inserted into the first slot plate 10, thereby achieving locking, thereby avoiding deviation of the conveying frame 71 due to vibration during transportation.

[0032] See also Figure 2 , Figure 3 , Figure 6 In one embodiment, a second stop column 13 is fixedly installed on the side of the connecting rod 11 away from the first stop column 12, a second notch plate 52 is installed on the second stop column 13, a piston 53 is fixedly installed on the second notch plate 52, an air cavity 5 is fixedly installed on the frame 4, the piston 53 is slidingly and sealingly connected to the inner wall of the air cavity 5, a connecting pipe 19 is penetrated on the inner wall of the conveying frame 71, the connecting pipe 19 is connected to the air cavity 5, and a through opening 18 corresponding to the connecting pipe 19 is opened on the conveying frame 71.

[0033] In this embodiment, a mounting rod 51 is fixedly mounted on the second notch plate 52, and a piston 53 is fixedly mounted on one end of the mounting rod 51 away from the second notch plate 52. The connecting pipe 19 is connected to the air cavity 5 via a hose (not shown in the figure). When the conveying frame 71 moves from the wet ore feeding position to the dry ore feeding position, the piston 53 moves in the air cavity 5, and the air is squeezed so that the air overflows from the connecting pipe 19, thereby blowing and drying the surface of the conveyor belt 7 that transports the wet ore through the air, which facilitates the feeding of the dry ore.

[0034] In one embodiment, a heating element (not shown in the figure) is installed in the air cavity 5.

[0035] In this embodiment, a heating element is provided to heat the air in the air cavity 5. The air flow rate of the hot gas overflowing from the connecting pipe 19 can be increased by the principle of thermal expansion of the air. The drying efficiency can be further improved by increasing the flow rate and the air temperature, thereby drying the surface of the conveyor belt 7.

[0036] See also Figure 8 In one embodiment, a transmission shaft 16 is rotatably mounted on the conveying frame 71 , a convex plate 17 is fixedly mounted on the transmission shaft 16 , and the transmission shaft 16 is transmission-connected to the rotating shaft 72 via a transmission member 76 .

[0037] In this embodiment, by providing a convex plate 17, the conveyor belt 7 can appear to be raised while the conveyor belt 7 is conveying. The raised position is located at the center of the bottom of the raw material bin 3. The convex plate 17 contacts the conveyor belt 7 to form a bulge, so that when feeding, the material appears on the surface of the conveyor belt 7 as a material pile with a certain distance. The distance between the material piles is formed by the convex plate 17. By providing a certain distance, that is, leaving a certain time interval, the feeding speed and feeding interval of the screen drum 1 can be controlled.

[0038] See also Figure 7 , Figure 8 In one embodiment, a material guide plate 77 is fixedly mounted on one end of the conveying frame 71 close to the screen drum 1 .

[0039] In this embodiment, the material guide plate 77 is installed to facilitate material discharge and guide the material.

[0040] See also Figure 7 , Figure 8 In one embodiment, a scraper 75 is fixedly mounted on one end of the conveying frame 71 close to the screen drum 1 , and one end of the scraper 75 is in contact with the conveyor belt 7 .

[0041] In this embodiment, the scraper 75 is provided to scrape the residual material on the conveyor belt 7 , and the scraper 75 has the same inclination direction as the guide plate 77 , so as to guide the scraped material so that the material pours onto the guide plate 77 .

[0042] See also Figure 3 , Figure 7 In one embodiment, a support leg 74 is fixedly mounted on the conveying frame 71 , and a roller 78 is rotatably mounted on the support leg 74 .

[0043] In this embodiment, the installation of the roller 78 can reduce the friction force when the conveying frame 71 moves, so that the conveying frame 71 moves more smoothly.

[0044] See also Figure 4 , Figure 5 In one embodiment, a first rolling groove 43 corresponding to the roller 78 is opened at one end of the frame 4 close to the screen drum 1, and a second rolling groove 44 corresponding to the roller 78 is opened at one end of the frame 4 away from the screen drum 1, and the depth of the second rolling groove 44 is greater than the depth of the first rolling groove 43.

[0045] In this embodiment, by providing the first rolling groove 43 and the second rolling groove 44, the roller 78 can be limited during the movement to prevent the roller 78 from being offset during the movement. Secondly, by deepening the depth of the second rolling groove 44, the height of the conveying frame 71 is lowered when conveying dry mineral materials, so that the distance between the conveying frame 71 and the bottom of the raw material bin 3 is increased, thereby increasing the thickness of the material spread on the conveyor belt 7, thereby increasing the conveying efficiency of the side guard conveyor 2.

[0046] Working principle: When feeding the wet mineral material, the second driving member 15 drives the connecting rod 11 to rotate, and the connecting rod 11 pulls the first notch plate 10 to move linearly while rotating, that is, drives the conveying frame 71 to move linearly. When the conveying frame 71 is about to move to the specified position, the first wedge block 91 contacts the second wedge block 92. In the process of continuing to move, the first wedge block 91 pushes the second wedge block 92 down. When the first wedge block 91 contacts the horizontal surface of the second wedge block 92, the sliding column 8 connected to the second wedge block 92 Inserted into the first notch plate 10, thereby locking, the wet mineral material can be fed at this time. When feeding, the wet mineral material is first put into the raw material bin 3, and then discharged to the conveyor belt 7 through the raw material bin 3. The conveyor belt 7 is driven by the first driving member 73 to rotate. While the conveyor belt 7 is conveying, the conveyor belt 7 is raised at the bottom of the feed bin due to the convex plate 17. The raised position is located at the center of the bottom of the raw material bin 3. The convex plate 17 contacts the conveyor belt 7 to form a bulge, so that when feeding, the material appears as a material pile with a certain distance on the surface of the conveyor belt 7. , the feeding speed and feeding interval of the screen drum 1 are controlled, so that the material is fed into the screen drum 1 through the guide plate, so as to carry out subsequent material screening and impurity removal, rubbing and selection, desludging, wet magnetic separation, dehydration and drying, and titanium dry magnetic separation. When it is necessary to feed dry mineral materials, the dry mineral materials are fed into the raw material bin 3, and then the second driving member 15 is driven, and the connecting rod 11 is driven to rotate by the second driving member 15. While the connecting rod 11 rotates, the first notch plate 10 is pulled to move linearly, that is, the conveying frame 71 is driven to move linearly until one end of the conveying frame 71 moves to the sidewall conveyor. Above the conveyor 2, during the movement, the piston 53 moves in the air cavity 5, and the air is squeezed to overflow from the connecting pipe 19, so that the surface of the conveyor belt 7 that transports the wet ore is blown and dried by the air. When the first notch plate 10 moves to the farthest point, the sliding column 8 is driven by the locking assembly 9 to move into the notch of the first notch plate 10, so as to lock the position of the conveyor frame 71. At this time, the roller 78 is located in the second rolling groove 44, so that the distance between the conveyor frame 71 and the bottom of the raw material bin 3 is increased, thereby increasing the thickness of the material laid flat on the conveyor belt 7.
