Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal equipment in mining, and specifically relates to a dust removal device for outdoor ore unloading. Background Technology

[0002] Currently, iron ore pellets are transported by truck. The loading volume is controlled by a funnel-shaped valve below the finished ore trough. The feeding device is covered with a flared opening and directly connected to a dust collection pipe. This dust collection system is simple in configuration, with strong suction at the center but weak suction at the edges, resulting in low dust collection efficiency. A large amount of dust raised during loading is only collected near the dust collection pipe, and areas far from the suction port cannot be effectively collected, causing dust to spill over onto the site. Especially in windy weather, this causes serious secondary pollution, creating a poor working environment, endangering the health of employees, and failing to meet on-site dust control standards. Summary of the Invention

[0003] The purpose of this utility model patent is to address the problems existing in the dust removal equipment used for unloading ore pellets onto trucks, and to provide a dust removal device for outdoor ore unloading. This utility model device features strong dust absorption capacity, good sealing performance, flexible control, reduced secondary pollution, and improved environmental protection level of on-site equipment.

[0004] An outdoor dust removal device for ore unloading includes a main dust collection pipe, a secondary dust collection pipe, a dust collection hopper, a cyclone pipe, an upper box, a lower box, a hydraulic telescopic support, and a flexible dustproof cloth.

[0005] The main suction pipe is connected to the top of several branch suction pipes. The bottom of the branch suction pipes is connected to the top of the suction hopper located in the upper box. The bottom of the suction hopper is fixedly connected to the bottom plate of the upper box. The top plate of the upper box has through holes corresponding to the branch suction pipes and through holes for the discharge pipe. The bottom plate has through holes corresponding to the top of the cyclone tubes and through holes for the discharge pipe. The top of the lower box is fixedly connected to the bottom plate of the upper box. Its top and bottom are open. There are several cyclone tubes located in the lower box. Their tops are fixedly connected to the bottom plate of the upper box. Cyclone elements are installed inside the tubes. Hydraulic supports with retractable support rods are provided around the lower box. Flexible sealing cloth for surrounding the truck bed is installed on the supports.

[0006] Furthermore, in the aforementioned outdoor dust removal device for ore unloading, the end of the dust suction pipe is connected to a negative pressure fan.

[0007] Furthermore, the aforementioned outdoor dust removal device for unloading ore has a positioning sensor on the ground below the lower box body for adjusting the position of the truck.

[0008] Furthermore, the aforementioned outdoor dust removal device for ore unloading also includes a voice warning device on its positioning sensor.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] 1. This device has a large dust collection range, strong absorption capacity, and high dust collection efficiency.

[0011] 2. The device has good sealing properties, which solves the problem of dust leakage and is suitable for windy weather.

[0012] 3. The device has a simple structure, is easy to maintain, and is flexible in control. It reduces secondary dust pollution, protects the on-site environment, reduces the labor intensity of workers, and improves the overall environmental protection level of enterprises.

[0016] The components include: 1. Main suction pipe, 2. Sub-suction pipe, 3. Cyclone tube, 4. Upper housing, 5. Lower housing, 6. Hydraulic telescopic support, 7. Positioning sensor, 8. Flexible dustproof cloth, 9. Suction hopper, and 10. Discharge pipe. Detailed Implementation

[0017] Example

[0018] An outdoor dust removal device for ore unloading includes a main dust collection pipe 1, a secondary dust collection pipe 2, a dust collection hopper 9, a cyclone pipe 3, an upper box 4, a lower box 5, a hydraulic telescopic support 6, a positioning sensor 7, and a flexible dustproof cloth 8.

[0019] The main dust collection pipe is connected to a negative pressure fan at its end. The main dust collection pipe is connected to the top of several branch dust collection pipes. The bottom of each branch dust collection pipe is connected to the top of a dust collection hopper located inside the upper housing. The bottom of the dust collection hopper is fixedly connected to the bottom surface of the upper housing. The top plate of the upper housing has through holes corresponding to the branch dust collection pipes and through holes for the discharge pipe 10. The bottom plate has through holes corresponding to the top of the cyclone pipe and through holes for the discharge pipe. The discharge pipe passes through the upper housing and into the lower housing. The upper housing is connected to the exterior wall via fixed brackets and expansion bolts. The top of the lower housing... The lower compartment is fixedly connected to the bottom plate of the upper compartment, with its top and bottom open. Several cyclone tubes are located in the lower compartment, with their tops fixedly connected to the bottom plate of the upper compartment. Cyclone generators are installed inside the tubes. Hydraulic supports with retractable struts are installed around the lower compartment, and flexible sealing cloth for surrounding the truck bed is installed on the supports. The upper and lower ends of the flexible dustproof cloth are fixed to the upper and lower parts of the hydraulic telescopic supports, respectively. The dustproof cloth can extend and retract with the extension and retraction of the hydraulic telescopic supports. A positioning sensor for adjusting the position of the truck is installed on the ground below the lower compartment. The positioning sensor is also equipped with a voice warning device.

[0020] The method of using this device is as follows:

[0021] The truck is driven under the lower cargo box, positioning the truck bed within the four corners of the positioning sensor coil. This positioning sensor is connected to a voice warning system, helping the driver adjust the vehicle's position to ensure the ore truck is parked within the designated area. Once the entire truck is in the designated area, the voice warning system announces readiness. Then, the dust cover is lowered, the dustproof device is activated, and loading begins. The flexible sealing cloth slides down the support rod to the bottom, forming a sealed space to prevent dust from escaping. Simultaneously, the negative pressure of the fan generates strong centrifugal force, improving dust collection capacity. Multiple cyclone tubes optimize airflow distribution, increasing the suction power of the device at various points. Furthermore, the dust cover is particularly effective in windy weather, while also reducing airflow loss and enhancing dust capture capabilities.
