Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing application technology, and in particular to a flexible material distribution system suitable for belt conveyors. Background Technology
[0002] In the field of mineral processing, ore material distribution is a common process requirement, and almost every processing plant needs to distribute materials as evenly as possible into different systems. In conventional production, wet materials (slurry) are usually stored in storage containers and then distributed via pipelines; this is not the scenario discussed in this patent and will not be elaborated upon here. Dry materials (or materials with low moisture content) are often distributed in two ways: 1. The incoming material enters the ore bin from the top, and the bottom of the bin has openings according to the subsequent distribution quantity requirements. A feeding device with controllable feed rate is installed at the openings to achieve even distribution. 2. When the incoming material is relatively uniform, this is commonly seen in belt conveyors, where the material accumulates on the belt surface and generally forms a relatively stable waterfall flow after the belt reaches its end. In most sizing plants, an inverted "Y"-shaped bifurcation funnel is installed at the material drop point of the conveyor belt. The bifurcation point is located on the center line of the conveyor belt surface. When the material particle size is ≤50mm, the material waterfall can usually be divided into two parts relatively evenly. After the bifurcation, the material is introduced into two different drop points through the two paths after the bifurcation point.
[0003] In actual application scenarios at mineral processing plants, to ensure the overall operating rate of the mineral processing process and prevent equipment with high failure rates or frequent replacement of spare parts from affecting overall production, backup equipment is often provided for critical processes or processes with frequent equipment maintenance. For a single-point unloading conveyor belt, the subsequent discharge requires the receiving equipment to achieve dual-use and one-backup operation. This means scientifically and economically splitting the incoming material into two streams, which can be flexibly distributed at any of the three outlet points. Fully realizing the process requirement of dual-use and one-backup operation with flexible switching of the discharge pipe receiving equipment has always been a challenging problem for dry materials (or materials with low moisture content). Utility Model Content
[0004] In order to achieve two uses and one backup based on the bifurcated funnel material distribution, this application provides a flexible material distribution system suitable for belt conveyors.
[0005] This application provides a flexible material distribution system suitable for belt conveyors, employing the following technical solution:
[0006] A flexible material distribution system suitable for belt conveyors includes a primary branching funnel and a secondary branching funnel. Both the primary and secondary branching funnels include an inlet pipe and two outlet pipes. The primary branching funnel is located at the top of the hopper and is vertically installed, with the end of the belt conveyor connected to the inlet pipe. The secondary branching funnel is located below the primary branching funnel, with its inlet pipe connected to the outlet pipe of the primary branching funnel, and adjacent outlet pipes interconnected. Each outlet pipe of the secondary branching funnel is equipped with an electric valve.
[0007] Optionally, both the primary branching funnel and the secondary branching funnel are fixed to the floor slab or beam of the silo by steel cables.
[0008] Optionally, the two discharge pipes on the primary branched funnel are mirror images of each other about the axis of the inlet pipe, and the two discharge pipes on the secondary branched funnel are mirror images of each other about the axis of the inlet pipe.
[0009] In summary, this application includes the following beneficial technical effects:
[0010] This application, through the setting of secondary branching funnel, primary branching funnel and electric valve, enables the ore to be separated after being sent to the primary branching funnel by the belt conveyor. At this time, by controlling the opening and closing of the electric valve, the evenly divided material can be introduced into any two of the three discharge ports, effectively realizing the requirement of material to be divided into two in the mining process, and the divided material must also meet the process requirements of two-in-one standby equipment at the outlet.

[0014] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.
[0015] This application discloses a flexible material distribution system suitable for belt conveyors. The material distribution system includes a primary branching funnel 2 and a secondary branching funnel 3. The two have the same structure but different installation positions. Both include an inlet pipe 4 and two outlet pipes 5. The inlet pipe 4 and the two outlet pipes 5 are connected and are in an inverted Y shape. The two outlet pipes 5 are mirror images of each other about the axis of the inlet pipe 4. Therefore, when the uniform ore enters the outlet pipes 5 from the inlet pipe 4, it will be divided into two parts.
[0016] The primary branching funnel 2 is set on the top of the silo and fixed to the floor slab 8 or beam of the silo by steel cable 7. The material flow from the belt conveyor 1 is delivered to the inlet pipe 4 of the primary branching funnel 2. The inlet pipe 4 of the secondary branching funnel 3 is connected to the two outlet pipes 5 of the primary branching funnel 2. At the same time, the secondary branching funnel 3 is also hung on the floor slab 8 or beam of the silo by steel cable 7. The two adjacent outlet pipes 5 of the secondary branching funnel 3 are interconnected. At the same time, each of the four outlet pipes 5 of the secondary branching funnel 3 is equipped with a solenoid valve 6.
[0017] The working principle of this material distribution system is as follows: Material enters the feed pipe 4 of the distribution system from the belt conveyor 1. When passing through the primary branching funnel 2, the material flow is evenly divided by 1 / 2. The divided material enters the secondary branching funnel 3 respectively. On the upper passage of the four discharge pipes 5 of the secondary branching funnel 3, by controlling the opening and closing of the electric valves, the evenly divided material can be guided into any two of the three discharge pipes 5. For example, closing the second and fourth electric valves on the left and opening the first and third electric valves on the left can realize the discharge of material from the first and second discharge pipes 5 on the left; closing the second and third electric valves on the left and opening the first and fourth electric valves on the left can realize the discharge of material from the first and third discharge pipes 5 on the left; closing the first and third electric valves on the left and opening the second and fourth electric valves on the left can realize the discharge of material from the second and third discharge pipes 5 on the left.
[0018] This material distribution system avoids the problems associated with using ore bins, such as high investment, low volume utilization, and large required elevation differences. It also avoids the issue of using a bifurcated funnel to divide the material into two, which lacks a backup outlet and fails to meet the dual-use, one-standby process requirement for the discharge equipment. It is cost-effective, easy to manufacture and install, simple to maintain, and fully meets the dual-use, one-standby material distribution requirements, making it highly suitable for widespread application.
[0019] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
