Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of mineral processing engineering equipment, specifically relating to a switchable high-low precision mixed non-powered conveying device. Background Technology
[0002] The current method of conveying concentrate involves conveying high and low concentrations separately. Although the target concentrate can be conveyed simultaneously by two sets of slurry pumps, this method greatly increases the conveying cost and generates unnecessary electricity consumption.
[0003] For example, a mineral processing plant with a capacity of 11,000 t / d produces two types of concentrate: high-grade nickel concentrate and low-grade nickel concentrate. The concentrate is currently transported to pump stations #4 and #6 via two sets of 200KBY-6 and 80KBY-4 slurry pumps, two pumps per set, for a total of four pumps. To meet the production organization requirements of "cost reduction and energy efficiency optimization," it is now necessary to uniformly transport both high-grade and low-grade concentrate to pump station #4. The existing configuration would then consume excessive amounts of electricity.
[0004] In summary, the existing technology has the following problems: The current concentrate conveying methods used on-site cannot meet the requirements of mixed conveying, and separate conveying would generate excess electricity. Furthermore, the reversibility of the conveying method must be considered; once production needs are restored to normal, it must be ensured that it can be switched back to separate conveying methods. Utility Model Content
[0005] This invention provides a switchable high and low concentrate mixed non-powered conveying device, which can not only realize the switching between unified and separate conveying of concentrate, but also save the power consumption of concentrate conveying.
[0006] Therefore, the present invention adopts the following technical solution:
[0007] A switchable high-precision and low-precision mixed non-powered conveying device includes a chute placed on a platform, with two slots on the chute, one slot located at the front of the chute and the other slot located in the middle of the chute; flow-blocking baffles are inserted into the slots, and pull rings are installed on the flow-blocking baffles; a discharge port on the chute is connected to a high-precision pump tank; and a feed port on the chute is connected to a low-precision sampling chamber.
[0008] Furthermore, the chute has three sides (side and bottom) welded together with 5mm thickness; the top surface of the chute is covered with an 8mm steel grating; the chute is 3.5m long, 1m wide, and 0.6m high; the length of the steel grating is the same as that of the chute; and the width of the steel grating is the same as that of the chute.
[0009] Furthermore, there are two slots; the slots are respectively welded to the side of the chute near the low-precision pump pool at 1 / 5 and the chute at 1 / 2; the flow-blocking baffle can be moved and disassembled vertically through the slots.
[0010] Furthermore, the flow-blocking plates are made of 2mm steel plates and are inserted into the slots; furthermore, pull rings are welded onto the flow-blocking plates;
[0011] Furthermore, the chute is provided with a discharge port on the side near the high-precision pump tank, which is connected to the high-precision pump tank.
[0012] The advantages of this invention are as follows: the switchable high-low concentrate mixing non-powered device can be selected to separately transport or mix high- and low-concentrate concentrates according to production organization requirements. The mixing process of the non-powered device does not require external power; it only relies on the potential energy generated by the elevation difference in the plant's pipelines for gravity-flow transport. This switchable high- and low-concentrate mixing non-powered conveying device has a simple structure, low cost, and is easy to operate and maintain. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1 and attached Figure 2 The structure of this utility model is described in detail.
[0017] A switchable high-low precision mixed non-powered conveying device is provided with a chute 3, the installation angle of the chute 3 is at a 3° angle with the horizontal plane; the length × width × height of the chute 3 is 3500mm × 1000mm × 600mm; the side walls and bottom of the chute 3 are welded from 5mm steel plates.
[0018] Two slots 12 are installed on the chute 3; a flow-blocking baffle 1 and a flow-blocking baffle 2 are inserted into the slots 12. The flow-blocking baffle 1 is located on the 1 / 5 side of the low-precision pump tank, and the flow-blocking baffle 2 is located at the 1 / 2 position of the chute. The flow-blocking baffles are made of 2mm steel plates, and pull rings are welded on the flow-blocking baffle plates; a discharge port 4 is provided on the bottom surface of the chute 3; a feed port 13 is provided on the side of the chute 3; a steel grating 14 is installed on the top of the chute, and the thickness of the steel grating is 8mm.
[0019] A switchable high- and low-precision mixed non-powered conveying device is placed on platform 5. The chute inlet 13 is connected to the low-precision sampling box 6; the chute outlet 4 is connected to the high-precision pump tank 11.
[0020] Due to production organization needs, sometimes high-grade and low-grade concentrates need to be combined and transported to pump rooms #4 and #6, and sometimes they need to be transported separately. To save costs and avoid additional power consumption, a switchable high- and low-grade concentrate mixing non-powered conveying device was installed based on the site layout and slurry flow. This switchable high- and low-grade concentrate mixing non-powered conveying device is installed on the plant's inherent platform 5. Low-grade concentrate flows through low-grade foam pipe 8 through low-grade sampling box 6, and then enters chute 3 through inlet 13. High-grade concentrate flows through high-grade foam pipe 9 through high-grade sampling room 7 and is transported to high-grade pump pool 11. If mixed conveying is required according to production organization requirements, flow barrier 2 can be inserted and flow barrier 1 can be removed. At this time, low-grade concentrate flows through outlet 4 and enters and exits high-grade pump pool 11. Concentrates can be uniformly transported by high-grade slurry pump. If high-grade and low-grade concentrates are to be transported separately according to production organization requirements, the No. 2 flow-blocking baffle 2 can be removed and the No. 1 flow-blocking baffle 1 can be inserted. The low-grade concentrate then directly enters the low-grade concentrate pump tank 10, and the concentrate is then transported to the pump room via the high-grade and low-grade concentrate slurry pumps respectively. This not only meets the changing production organization needs, but also its simple design facilitates operation by personnel and offers numerous advantages such as low cost, high efficiency, and convenient maintenance.
