Description

Technical Field

[0001] The utility model relates to the technical field of drying silos, in particular to an iron ore concentrate drying silo. Background Art

[0002] Iron ore concentrate refers to the mineral powder formed after the ore is processed through crushing, grinding, beneficiation, etc. After the production of iron ore concentrate, some fine impurity particles may still remain inside, such as clay or mica. These impurities may affect the quality of the iron ore concentrate. The impurities attached to the surface of the iron ore concentrate can be removed by cleaning. After cleaning, it needs to be poured into the drying silo for drying.

[0003] When pouring iron ore fines into the drying silo, it is usually poured directly from the feed port of the drying silo. When the iron ore fines are poured from a higher position, a greater impact force will be generated during the falling process, thereby raising the fine particles in the iron ore fines to form dust. Especially when the pouring speed is fast and the height is high, the falling impact force is greater, the amount of dust raised will be greater, and the generated dust will float in the air, which may cause harm to the health of the workers. Utility Model Content

[0004] The utility model provides an iron ore concentrate drying silo, which solves the problem in the prior art that dust may be generated at the silo opening when the iron ore concentrate is poured into the drying silo, thereby causing harm to workers.

[0013] 1. In the present invention, when drying the iron ore concentrate, the crushed iron ore concentrate can be directly dropped into the receiving plate after being rinsed by opening the valve. Since the iron ore concentrate falls onto the receiving plate through the valve, the flow rate is lower than that of direct pouring, and less dust is generated. In addition, the distance between the valve and the receiving plate is closer, which can effectively prevent the generation of dust.

[0014] 2. In the present invention, after the iron ore fines fall onto the receiving plate, the opening and closing plate can be opened by the opening and closing assembly, and then the iron ore fines on the receiving plate can be poured into the bin for drying by the material pouring assembly. When the receiving plate is poured into the bin, the dust generated by it can be protected by the dust cover to prevent it from being scattered to the crowd. In addition, the flow rate of the iron ore fines can be controlled by adjusting the angle of the receiving plate, thereby controlling the generation of dust.

[0015] To sum up, the device can reduce or eliminate dust generation when dumping the crushed iron ore concentrate through the mutual cooperation between the material dumping component, the material receiving plate, the opening and closing component and the dust cover. Compared with the existing technology, it can reduce dust generation and thus protect the health of the workers. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0023] like Figures 1 to 4 As shown, this embodiment proposes an iron ore concentrate drying silo, including a silo body 1, a silo cover 2 and a crushing box 3. The silo cover 2 is fixedly mounted on the silo body 1, and the crushing box 3 is fixedly mounted on the side of the silo body 1 through a connecting rod 4. The length of the silo cover 2 is half the length of the silo body 1, and a valve 5 is installed at the bottom end of the crushing box 3. The iron ore blocks can be placed in the crushing box 3, crushed into powder, and then dropped into the drying box by opening the valve 5. This method can directly reduce the generation of dust when the iron ore concentrate is produced and poured into the silo body 1, and the valve 5 is located above the receiving plate 6 and is relatively close.

[0024] It also includes a material dumping assembly, a material receiving plate 6, an opening and closing assembly and a dust cover 7. The material dumping assembly is arranged on the silo body 1 and is used to dump iron ore concentrate. The material receiving plate 6 is arranged on the material dumping assembly, and the material receiving plate 6 is arranged in an arc shape. The opening and closing assembly is arranged on the silo body 1, and the dust cover 7 is fixedly installed on the silo body 1.

[0025] In this embodiment, reference Figure 2The material dumping assembly includes a mounting plate 101, a rotating shaft 102 and a motor 103. There are two mounting plates 101, which are fixedly mounted on both sides of the bin body 1 respectively. There are two rotating shafts 102, which are rotatably mounted on the sides of the two mounting plates 101 respectively, and the receiving plate 6 is fixedly mounted between the two rotating shafts 102. The motor 103 is mounted on the side of one of the mounting plates 101, and the output end of the motor 103 is fixedly connected to the side of one of the rotating shafts 102.

[0026] By rotating the receiving plate 6, the receiving plate 6 can be tilted to a certain angle, so that the powder on the receiving plate 6 slowly slides into the bin body 1 for subsequent drying. The slow flow can reduce the generation of dust.

[0027] In this embodiment, reference Figure 3 The opening and closing assembly includes a cylinder 201, an opening and closing rod 202 and an opening and closing plate 203. There are two cylinders 201, which are respectively installed on both sides of the warehouse body 1. There are two opening and closing rods 202, which are respectively fixedly connected to the output ends of the two cylinders 201. The opening and closing plate 203 is slidably installed on the top of the warehouse body 1. The opening and closing plate 203 is fixedly connected to the sides of the two opening and closing rods 202. The length of the opening and closing plate 203 is half the length of the warehouse body 1.

[0028] The silo 1 can be half opened by the opening and closing assembly, so that the discharge port of the receiving plate 6 can be rotated to the opening of the silo 1 for dumping, and the dust cover 7 on the silo 1 can also prevent dust from escaping during dumping. A slide groove is provided at the top of the silo 1, and a slider is fixedly installed at the bottom end of the dust cover 7, and the slider is slidably installed on the slide groove of the opening and closing plate 203. When the opening and closing plate 203 slides, it can slide with the bottom end of the dust cover 7 through the slider, thereby avoiding friction between the bottom end of the dust cover 7 and the top end of the opening and closing plate 203.

[0029] In this embodiment, reference Figure 2 , also includes a support assembly, the support assembly includes a support rod 301 and a support plate 302, two support rods 301 are provided, the two support rods 301 are fixedly mounted on the connecting rod 4, and the support plate 302 is fixedly mounted on the top of the two support rods 301.

[0030] When the iron ore fines leaking from the valve 5 fall onto the receiving plate 6, the support plate 302 can support it to prevent the receiving plate 6 from tilting to the opposite position of the opening and closing plate 203, thereby causing the iron ore fines to spill. The support plate 302 is arranged to be arc-shaped, and the curvature of the support plate 302 is consistent with the curvature of the receiving plate 6. The top end of the support plate 302 contacts the bottom end of the receiving plate 6, which can effectively support the bottom end of the receiving plate 6.

[0031] In this embodiment, when the iron ore fines are dried, the material blocks for producing the iron ore fines can first be placed in the crushing box 3 for crushing. If cleaning is required, the material blocks can be cleaned in the crushing box 3. After cleaning, when drying is required, the valve 5 can be opened to allow the iron ore fines to fall onto the receiving plate 6. Since less dust is generated after cleaning, there may still be dust. When the iron ore fines fall, the support plate 302 can support the receiving plate 6, and then the cylinder 201 is started, and the cylinder 201 drives the opening and closing rod 202 to move, and the opening and closing rod 202 drives the opening and closing rod 202 to move. The opening and closing plate 203 moves forward to open the opening of the silo 1, and is opened to the discharge port of the receiving plate 6 so that the material can be poured into the opening without spilling outside. At this time, the opening is still within the protection range of the dust cover 7. Then the motor 103 is started, and the motor 103 drives the rotating shaft 102 to rotate. The rotating shaft 102 drives the receiving plate 6 to rotate. The receiving plate 6 is tilted at a certain angle to pour the iron ore powder into the silo 1. The dust cover 7 can protect it from dust during pouring. If dust is generated, the dust cover 7 can ensure that it will not float outside.

[0032] It should be added that a door is hingedly installed on the side of the warehouse body 1. After drying, the door can be opened to take out the iron ore powder, and a resistance wire is installed on the inner wall of the warehouse body 1 to heat and increase the temperature inside.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
