Description

Technical Field

[0001] This utility model relates to the field of mineral processing automation technology, specifically to an automatic dust removal device for mineral processing based on pneumatic control. Background Technology

[0002] Mineral beneficiation is a process that, based on the physical and chemical properties of different minerals in an ore, involves crushing and grinding the ore, and then using methods such as gravity separation, flotation, magnetic separation, and electrostatic separation to separate useful minerals from gangue minerals, and to separate various associated (symbiotic) useful minerals as much as possible, thereby removing or reducing harmful impurities in order to obtain raw materials required for smelting or other industries. In the mineral processing industry, dry operations such as magnetic separation and electrostatic separation easily generate a large amount of metal dust, posing a serious threat to the occupational health of operators. Existing dust removal technologies mostly rely on fixed dust removal facilities. However, during ore feeding operations, due to the repeated dumping of fine-grained metal into the feed bin, dust can still escape through open gate valves. Traditional mechanical limit switches are easily damaged by operational impacts, and pneumatic gate valves have insufficient sealing, leading to dust leakage problems. Traditional dust removal devices rely on manually controlled gate valves, which are inefficient and have lag. At the same time, existing automated dust removal systems have limitations in terms of dynamic response and reliability. Utility Model Content

[0003] The purpose of this invention is to provide an automatic dust removal device for mineral processing based on pneumatic control, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An automatic dust removal device for mineral processing based on pneumatic control includes a ore bin, a transport ore drum mounted on the ore bin, and a crane mounted above the transport ore drum. The crane moves the transport ore drum via a hook. The device is characterized by further comprising: An outer cylinder is disposed between the ore bin and the transport ore drum; A pneumatic limit switch is installed at the top of the outer cylinder, and the pneumatic limit switch is connected to an air compressor. A pneumatic dust butterfly valve is installed in the middle section of the outer cylinder, and an air pipe is connected between the pneumatic dust butterfly valve and the pneumatic limit switch.

[0005] Furthermore, the pneumatic limit switch is equipped with a pressure sensor, and the pressure signal transmitted by the pressure sensor is used to detect the feeding operation status in real time. The pressure sensor can control the airflow of the pneumatic limit switch.

[0006] Furthermore, the pneumatic dust butterfly valve is electrically connected to the pneumatic limit switch, and the pneumatic dust butterfly valve uses wear-resistant sealing material.

[0007] Furthermore, the pneumatic dust butterfly valve adopts a double-layer silicone sealing ring.

[0008] Furthermore, a sealed gate is provided inside the outer cylinder, and the output end of the pneumatic dust butterfly valve is connected to the sealed gate.

[0009] Furthermore, the outer cylinder is a circular cylinder, and the shape of the outer cylinder is consistent with that of the sealing gate.

[0010] Furthermore, a rubber ring is fitted onto the upper end of the outer cylinder.

[0011] Furthermore, a dust cover is provided on the upper end of the pneumatic limit switch.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Pneumatic limit switches replace traditional mechanical switches. They can control the rotation of the sealed gate through the pneumatic dust butterfly valve without the need for control circuits, thereby controlling the opening and closing of the outer cylinder. They have a fast response speed. 2. The pneumatic dust butterfly valve adopts a double-layer silicone sealing ring and an inclined valve plate structure, which reduces the dust leakage rate; 3. A rubber ring is fitted on the upper part of the outer cylinder to reduce dust leakage; 4. Adding a dust cover to the top of the pneumatic limit switch can prevent dust from spreading into the interior of the pneumatic limit switch, avoid blockage and malfunction, and increase its service life.

[0015] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0016] Example 1: Please see Figures 1 to 3This utility model provides a technical solution: an automatic dust removal device for mineral processing based on pneumatic control, including a ore bin 10, a transport ore drum 9 disposed on the ore bin 10, and a crane 8 disposed above the transport ore drum 9, the crane 8 driving the transport ore drum 9 to move via a hook, and further including: Outer cylinder 1, the outer cylinder 1 is disposed at the upper end of the ore bin 10; The transport ore drum 9 is moved above the outer cylinder 1 by the cooperation of the crane 8 and the hook.

[0017] Example 2: Please see Figures 1 to 3 A pneumatic limit switch 7 is provided at the top of the outer cylinder 1, and the pneumatic limit switch 7 is connected to an air compressor. A pneumatic dust butterfly valve 4 is provided in the middle section of the outer cylinder 1, and an air pipe 5 is provided between the pneumatic dust butterfly valve 4 and the pneumatic limit switch 7. The outer cylinder 1 is equipped with a rotatable sealing gate 2, which is connected to the output end of the pneumatic dust butterfly valve 4. Compared to traditional mechanical switches, the pneumatic limit switch 7 can control the pneumatic dust butterfly valve 4 to rotate the sealed gate 2 without the need for a circuit, and the response speed is fast; When the ore transport drum 9 is moved above the outer cylinder 1 by the crane 8, the ore transport drum 9 will squeeze the pneumatic limit switch 7, the pneumatic limit switch 7 will open, and the pneumatic dust butterfly valve 4 will be linked through the air pipe 5. The pneumatic dust butterfly valve 4 will drive the sealed gate 2 to rotate, so that the minerals enter the interior of the ore bin 10.

[0018] Example 3: like Figures 1-3 As shown, the automatic dust removal device for mineral processing based on pneumatic control disclosed in Embodiment 2 of this utility model has a structure that is basically the same as that in Embodiment 1, except that: A rubber ring 3 is fitted onto the upper end of the outer cylinder 1; The rubber ring 3 can seal the connection between the transport ore drum 9 and the outer cylinder 1, reducing the dust leakage rate; The upper end of the pneumatic limit switch 7 is provided with a dust cover 6, which can protect the pneumatic limit switch 7 and prevent dust from entering the interior of the pneumatic limit switch 7.

[0019] Specifically, the pneumatic limit switch 7 is installed at the top edge of the outer cylinder 1, and the pneumatic dust butterfly valve 4 is installed at the lower middle edge of the outer cylinder 1. When the feeding operation is started, the pneumatic limit switch 7 detects the pressure signal of the transport ore drum 9 and opens the passage, which in turn activates the pneumatic dust butterfly valve 4 to ventilate. The pneumatic dust butterfly valve 4 controls the opening of the sealing gate 2, allowing the minerals inside the transport ore drum 9 to enter the ore bin 10.
