Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] see figure 1 and figure 2 , a kind of umbrella-shaped baffle plate steady flow feeding box, comprising a box body, is provided with an ore discharge port 4 at the bottom of the box body, and the ore discharge concentration adopts a weight percentage concentration of 30-40%, and the ore discharge is stable; at the bottom of the box body The upper side wall is provided with an overflow port 3, which is located 25mm below the top of the side wall 1 of the box body. The flow pipes are connected; the other side wall of the lower part of the side wall 1 of the box is provided with an ore feeding port 5, and the inlet end of the ore feeding port 5 is connected with a feeding pipe with an inner diameter of 75mm; 30mm above the ore feeding port 5 The first baffle plate 6 is welded on the inner wall of the box. After rotating 30° according to the height...

The invention relates to an umbrella-shaped baffle steady flow feed chute and a manufacturing method thereof. In the feed chute, a discharge port is formed at the bottom of the chute body; an overflow port is formed on one lateral wall of the upper part of the chute body, and a feed port is formed on the other lateral wall of the lower part of the chute body; and a first baffle is soldered on theinner wall of the chute body 30mm higher than the feed port, and the next adjacent baffle is soldered on the inner wall of the chute body according to a height of every 200mm and a rotating angle of 30 degrees, so that all baffles arranged on the inner wall of the chute body can form a spiral structure. According to the slurry settlement theory of fluid mechanics, the umbrella-shaped baffles are adopted in the steady flow feed chute, so the baffles form the spiral structure in the steady flow feed chute, the umbrella-shaped baffle steady flow feed chute has a simple structure design, is easy and convenient to assemble, and achieves the aims of discharging concentration of between 30 and 40 percent, overflow concentration of between 0.5 and 2 percent and steady discharged slurry flow.
Description
technical field [0001] The invention belongs to the technical field of beneficiation equipment for metallurgical mines, and relates to an umbrella-shaped baffle steady-flow feeding box used for ore feeding from a sand pump in a beneficiation plant of a nonferrous metallurgical mine to a beneficiation equipment and a manufacturing method thereof. Background technique [0002] The steady flow feeding box is a necessary facility for the ore feeding from the sand pump to the beneficiation equipment in the non-ferrous metallurgical mine dressing plant. For the operating environment where the stability of the sand pump is poor and the ore feeding fluctuates greatly, because the ore feeding of the beneficiation equipment has a great impact on the concentration of the ore slurry and The slurry flow rate has higher requirements, which directly affects the better operation of the mineral processing equipment and the effective improvement of the production index of the mineral proce...
