Description

Technical Field

[0001] This utility model relates to the field of waste rock sorting technology, specifically a pre-sorting waste disposal device for lead-zinc mines. Background Technology

[0002] In the field of lead-zinc mining and processing, pre-selection waste disposal is a key link to improve ore utilization and reduce subsequent beneficiation costs. Its efficiency and accuracy directly affect the production efficiency of the entire mine. The pre-selection waste disposal device separates waste rock in advance by performing preliminary screening on the mined raw ore, and only retains the concentrate with recycling value to enter the subsequent processing process. This can greatly reduce the amount of ineffective transportation and processing, and save energy and resources. When sorting and discarding ore, it is placed on a conveyor belt, and high-definition cameras, light sources, and image processing modules are used to quickly identify refined ore or waste ore. However, in actual operation, the mined lead-zinc ore is often of mixed size and shape, and it is easy for it to accumulate and overlap on the conveyor belt. For example, larger pieces of ore may completely cover smaller pieces of ore, or multiple pieces of ore may be squeezed together to form densely packed areas, making it difficult for the identification system to clearly capture the characteristic information of individual pieces of ore and accurately distinguish between refined ore and waste ore. In order to solve the above problems, the inventors have proposed a pre-sorting waste disposal device for lead-zinc mines. Utility Model Content

[0003] To address the problem that mined lead-zinc ore often comes in mixed sizes and shapes, leading to accumulation and stacking on conveyor belts, making it difficult to accurately distinguish between refined ore and waste ore, this utility model aims to provide a pre-selection and waste disposal device for lead-zinc mines.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a pre-selection waste disposal device for lead-zinc mines, comprising a main box, an installation base fixedly connected to one side of the bottom of the main box, a conveyor belt provided at the top of the installation base, an installation box fixedly connected to the bottom of the main box near the installation base, a partition fixedly connected to the center of the installation box, a photoelectric detection device provided at the center of the top of the main box, a long box fixedly connected to the top of the main box near the photoelectric detection device, a nozzle provided at the center of the bottom of the long box, L-shaped rods symmetrically and slidably connected to the top of the long box near the center, and the two L-shaped rods are staggered, a long plate fixedly connected to the bottom of the L-shaped rods, and guide telescopic rods symmetrically and slidably inserted into the bottom of the long plate near the center, and a scraper plate fixedly connected between the bottom ends of the two guide telescopic rods.

The devices have not been structurally modified in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them proficiently. Thus, this paper will not elaborate on them further. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control.

It is worth emphasizing that although this solution does not describe the electrical control program in detail, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0018] A square box 47 is fixedly connected to the center of the bottom end of the long plate 46. An electric actuator 48 is installed inside the square box 47. The output end of the electric actuator 48 passes through the square box 47 and is fixedly connected to the scraper plate 49.

[0019] By adopting the above technical solution, the working electric actuator 48 is activated, thereby causing the fixedly connected scraper plate 49 to move horizontally.

[0020] A gear 41 is rotatably connected at the center of the top of the long box 4. A reciprocating motor 43 is installed at the center of the inside of the long box 4. The output end of the reciprocating motor 43 passes through the long box 4 and is fixedly connected to the gear 41.

[0021] By adopting the above technical solution, after the reciprocating motor 43 starts working, the fixedly connected gear 41 can rotate.

[0022] The top of the long box 4 has symmetrically staggered racks 42 near the center, and both racks 42 mesh with gears 41. The side end of the L-shaped rod 44 is fixedly connected to the racks 42.

[0023] By adopting the above technical solution, the two racks 42 mesh with the upper and lower tooth surfaces of the gear 41 respectively, thereby causing the two racks 42 to move towards each other.

[0024] A water tank 2 is located near the center of the front end of the main body 1. A transfer pipe 21 is fixedly connected to the bottom of the water tank 2, and the other end of the transfer pipe 21 passes through the main body 1 and is fixedly connected to the nozzle 45.

[0025] By adopting the above technical solution, a water inlet is provided at the top of the water tank 2, and a sealing gasket and a cap are provided at the water inlet.

[0026] A discharge port 11 is fixedly connected to the side end of the main housing 1.

[0027] By adopting the above technical solution, the discharge port 11 is installed on one side of the inlet of the main body 1, thereby realizing the work of adding materials into the interior.

[0028] An airflow nozzle box 35 is provided on the side of the mounting base 31 away from the discharge port 11.

[0029] By adopting the above technical solution, the specific installation height of the airflow nozzle box 35 can be selected according to actual usage requirements, and the identified waste rock can be accurately blown away from the conveyor belt 3.

[0030] Conveyor belts 34 are symmetrically arranged near the center inside the mounting box 32.

[0031] By adopting the above technical solution, the conveyor belt 34 near the inner side of the main box 1 is used to transport the pre-selected lead-zinc ore, and the outer conveyor belt 34 is used to transport the discarded waste rock. The conveying direction of the conveyor belt 34 is perpendicular to the conveyor belt 3 at a ninety-degree angle.

[0032] Working principle: When using this device, the ore to be pre-selected is first poured into the main box 1 through the discharge port 11, and an appropriate amount of clean water is added into the water tank 2. Then, the working conveyor belt 3 is started. When the material is close to the bottom of the long box 4, the reciprocating motor 43 is started, which causes the fixedly connected gear 41 to rotate. This causes the two meshing racks 42 to drive the L-shaped rod 44 to move towards each other, and causes the fixedly connected scraper plate 49 to move back and forth towards each other, thereby agitating the material piled up on the conveyor belt 3 (before operation, the electric push rod 48 needs to be started, so that the fixedly connected scraper plate 49 can be raised and lowered to adjust the height of the scraper plate 49). This can avoid the situation where the material is piled up and cannot be accurately and quickly identified as refined stone and waste stone. When the material approaches the long box 4, the valve on the transfer pipe 21 can be activated, so that water flows from the water tank 2 into the transfer pipe 21 and finally reaches the nozzle 45 and sprays downward, thereby cleaning the material and improving the accuracy of ore identification. Finally, after identification, the separation of refined stone and waste stone can be achieved through the airflow nozzle box 35.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
