Description

Technical Field

[0001] This utility model relates to the technical field of ore batching systems, and in particular to a fully automatic batching device. Background Technology

[0002] As is well known, naturally mined bauxite has a complex and unstable composition, while industrial production processes have high requirements for the chemical composition and physical properties of materials. Therefore, through scientific batching, ores of different grades can be mixed in proportion to make full use of mineral resources, reduce overall raw material costs, and produce qualified metallurgical products.

[0003] In the batching process, multiple batching hoppers are often used to feed materials proportionally onto a conveyor belt, which then transports them to a mixing mechanism. As the ore falls onto the conveyor belt, it inevitably carries fine particles, which generate dust during the fall, causing dust pollution. For example, Chinese utility model patent CN202656318U discloses an automatic ore batching device that employs a weighing and feeding mechanism, a batching conveyor belt, and a mixing mechanism. Through structural optimization, it can effectively manage dust.

[0004] However, the dust removal structures mentioned above, as well as most current dust removal structures, have a fixed suction range. This means they cannot dynamically adjust the suction space based on the quality of the material being collected and the content of fine particles, resulting in poor dust removal performance. Utility Model Content

The lifting mechanism includes a cylinder vertically installed on the outside of the weighing and feeding mechanism. A support ring is connected to the bottom end of the cylinder piston rod, and the bottom edge of the movable cover is connected to the support ring.

[0007] By adopting the above technical solution, the operator controls the cylinder, and the extension and retraction of the cylinder piston rod can drive the movable cover to extend or retract. When the movable cover is lowered, the dust collection area is more concentrated and the dust collection effect is better.

[0015] By adopting the above technical solution, the length of the installation connector can be finely adjusted to improve its applicability.

[0016] Preferably, the movable cover is detachably installed between the fixed cover and the support ring via a limiting mechanism.

[0017] By adopting the above technical solution, the movable cover can be replaced.

[0018] Preferably, a slot is provided on the bottom edge of the fixed cover peripheral plate from bottom to top, and a guide hole is provided on the outer wall of the peripheral plate. The top edge of the movable cover is detachably inserted into the slot. The limiting mechanism includes a U-shaped support frame fixed to the outer wall of the peripheral plate.

[0025] The following combination Figures 1-6The present invention will be described in further detail below.

[0026] This utility model discloses a fully automatic batching device. Example 1

[0027] Reference Figures 1-4 The fully automatic batching device includes multiple weighing and feeding mechanisms 1 arranged side by side. The weighing and feeding mechanism 1 adopts a hopper structure and is supported by a frame to maintain its stability. The weighing and feeding mechanism 1 can be any existing equipment with automatic weighing and material control functions, and there is no limitation on the model. Below the multiple weighing and feeding mechanisms 1, a conveyor belt 2 for conveying mineral materials is arranged, and the output end of the conveyor belt 2 is connected to a mixing device (not shown in the figure).

[0028] A dust removal mechanism 3 is installed at the discharge port of the weighing and feeding mechanism 1. The dust removal mechanism 3 includes a fixed cover 30 that is sleeved and fixed to the outside of the discharge port. The bottom of the fixed cover 30 is open, and its top plate is penetrated by the discharge port. Four partition plates 31 are fixed between the inner wall of the peripheral plate of the fixed cover 30 and the outer wall of the discharge port. The four partition plates 31 are evenly distributed around the discharge port. A dust removal ring pipe 32 is provided above the fixed cover 30. The dust removal ring pipe 32 is sleeved on the outside of the discharge port. Four dust removal branch pipes 33 are connected between the dust removal ring pipe 32 and the fixed cover 30. The four dust removal branch pipes 33 are evenly distributed around the discharge port. The connection point of any dust removal branch pipe 33 with the fixed cover 30 is located in the middle area between two adjacent partition plates 31.

[0029] Multiple weighing and feeding mechanisms 1 are horizontally arranged on the same side with a dust removal main pipe 34, which is connected to a dust collector, for example, by using a bag filter. A connecting pipe 35 connects the dust removal ring pipe 32 to the dust removal main pipe 34. A movable cover 36 is connected to the bottom edge of the peripheral plate of the fixed cover 30. The movable cover 36 is in the shape of an inverted funnel, with its top opening area being smaller than its bottom opening area. The movable cover 36 adopts a corrugated telescopic structure, which gives it good deformation performance.

[0030] A lifting mechanism 4 for driving the movable cover 36 to extend and retract vertically is also provided between the weighing and unloading mechanism 1 and the movable cover 36. The lifting mechanism 4 includes two fixed plates 40 symmetrically fixed to the outer wall of the hopper of the weighing and unloading mechanism 1. A vertically arranged cylinder 41 is fixedly installed on the top of the fixed plate 40. The piston rod of the cylinder 41 is arranged downward and passes through the fixed plate 40. An installation joint 42 is installed at the bottom end of the piston rod of the cylinder 41. A support ring 43 is connected to the bottom edge of the movable cover 36.

[0031] Two vertically arranged support rods 44 are symmetrically fixed to the top surface of the support ring 43. The top of the support rods 44 are connected to the piston rod of the cylinder 41 through the mounting joint 42. A reinforcing ring 45 is also fixed between the two support rods 44. The reinforcing ring 45 is sleeved on the outside of the movable cover 36. Multiple reinforcing rods 46 are also fixed between the bottom surface of the reinforcing ring 45 and the inner edge of the top surface of the support ring 43 to improve the stability of the support ring 43.

[0032] The mounting connector 42 includes two mounting tubes 420 arranged symmetrically in an upper and lower position. One end of each mounting tube 420 is open and the other end is closed. The closed ends of the two mounting tubes 420 are close to each other. A mounting rod 421 is fixedly connected to the middle of the closed end of each mounting tube 420. A mounting plate 422 is fixedly connected to the end of the mounting rod 421. The diameter of the mounting plate 422 is larger than the diameter of the mounting rod 421. A second mounting tube 423 is coaxially arranged on one side near the closed end of the first mounting tube 420. One end of the second mounting tube 423 is open and the other end is closed. An inward flange 424 is fixedly connected to the closed end of the second mounting tube 423. The mounting plate 422 is rotatably installed in the inward flange 424, so that the second mounting tube 423 can rotate relative to the first mounting tube 420 but cannot be separated from the first mounting tube 420. A threaded rod 425 is threaded between the two second mounting tubes 423. The upper first mounting tube 420 is threadedly connected to the piston rod of the cylinder 41, and the lower second mounting tube 423 is threadedly connected to the vertical support rod 44.

[0033] The implementation principle of Example 1 is as follows: Operators can autonomously control the dust collection space range according to the quality and particle content of the ore. This is achieved by controlling cylinder 41; the piston rod of cylinder 41 drives the support ring 43 to move up and down, which in turn causes the movable cover 36 to extend or retract. Lowering the movable cover 36 concentrates the dust collection area, improving the dust collection effect. Extending or retracting the movable cover 36 changes the dust collection range, thus dynamically controlling the dust collection effect. The dust collector generates a negative pressure environment, and dust particles are discharged from the outlet via the movable cover 36, fixed cover 30, dust collection branch pipe 33, dust collection ring pipe 32, connecting pipe 35, and dust collection main pipe 34. The mounting connector 42 uses a threaded installation, facilitating connection to the piston rod of cylinder 41 and the vertical support rod 44. The height of the support ring 43 can be finely adjusted by adjusting the exposed length of the threaded rod 425. This invention uses a structure of movable cover 36 combined with lifting mechanism 4, allowing for dynamic control of the dust collection range and further improving the dust collection effect. Example 2

[0034] Reference Figures 5-6The difference between this embodiment and Embodiment 1 is that the movable cover 36 is detachably installed between the fixed cover 30 and the support ring 43 via a limiting mechanism 5. Multiple limiting mechanisms 5 are arranged around the fixed cover 30. A ring-shaped slot 300 is formed from bottom to top on the peripheral plate of the fixed cover 30. The top edge of the movable cover 36 is inserted into the slot 300. A limiting groove 301 is provided on the inner side wall of the slot 300, and guide holes 302 are symmetrically formed on the outer side wall of the peripheral plate.

[0035] The limiting mechanism 5 includes a U-shaped support frame 50 fixed to the outer wall of the peripheral plate of the fixed cover 30. A Torx screw 51 is horizontally threaded in the middle of the U-shaped support frame 50. A baffle 52 is vertically arranged inside the U-shaped support frame 50. A top block 53 is fixed in the middle of the side of the baffle 52 away from the Torx screw 51. The top block 53 slides through the guide hole 302. Compression springs 54 are connected between the upper and lower ends of the side of the baffle 52 away from the Torx screw 51 and the outer wall of the peripheral plate of the fixed cover 30. A receiving groove 303 for receiving the compression spring 54 is opened on the outer wall of the peripheral plate of the fixed cover 30. The bottom edge of the movable cover 36 rests on the support ring 43 and is fixed together with the support ring 43 by limiting bolts 55.

[0036] The implementation principle of Example 2 is as follows: Rotating the tortoise-shaped hand screw 51 pushes the baffle 52, causing the top block 53 to press against the top edge of the movable cover 36 into the limiting groove 301, thereby fixing the top edge of the movable cover 36. The bottom edge of the movable cover 36 can be fixed by the limiting bolt 55. When the movable cover 36 needs to be replaced, the operation is reversed. The limiting mechanism 5 is easy to operate, can effectively fix the movable cover 36, and facilitates the replacement of the movable cover 36, improving the convenience of the replacement operation.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
