Embodiment 1

[0022] Such as figure 1 As shown, the solid-liquid separation equipment provided with a flocculant adding device in the present invention includes a body 1, a sedimentation plate 2 is installed inside the body 1, a console 3 is installed above the body 1, and a feeding cylinder is connected below the console 3, The discharge end of the feeding cylinder passes downward through the sedimentation plate 2 and is located inside the machine body 1. The feeding cylinder includes an inner cylinder 4 and a sleeve 5 sleeved outside the inner cylinder 4. The inner cylinder 4 and the sleeve 5 are arranged There is a passage 6, the inner cylinder 4 is connected with a slurry inlet pipe 7, the passage 6 is connected with a liquid inlet pipe 8, and a separation plate 9 is arranged below the feed cylinder, and the separation plate 9 includes a slant plate A with a through hole , slant plate B, one end of slant plate A is connected with one end of slant plate B to form an upwardly protruding s...

Embodiment 2

[0025] Based on Embodiment 1, a rotating shaft 10 is also connected below the console 3. The rotating shaft 10 is located inside the inner cylinder 4 and is concentric and coaxial with the inner cylinder 4. The lower end of the rotating shaft 10 passes through the separation plate 9 and is located at the bottom of the body 1. The rotating shaft 10 The lower end of the lower end is connected with a cross-shaped rake 11 perpendicular to the rotating shaft 10 . A hole is opened inside the rotating shaft 10 , and a fluid flow channel is opened in each push plate of the push rake 11 for the fluid inside the hole to be sprayed out.

[0026] The rotation of the rotating shaft drives the rake to rotate, and the cross-shaped rake can quickly push the thickened pulp out of the body. During the rotation of the cross-shaped rake, the pulp is stirred to further mix the pulp and flocculant. The hole inside the shaft is used to feed a small amount of flocculant into the pulp during the sedim...

Abstract

The invention discloses a solid-liquid separation apparatus with a flocculating agent adding device. The solid-liquid separation apparatus comprises a body, wherein a sludge settling plate is mounted in the body; a console is mounted above the body; a feed cylinder is connected below the console; a discharge end of the feed cylinder downward passes through the sludge settling plate and is positioned in the body; the feed cylinder comprises an inner cylinder and a sleeve in sleeve joint with the exterior of the inner cylinder; a channel is formed between the inner cylinder and the sleeve; the inner cylinder is communicated with a pulp-in pipe; the channel is communicated with a liquid-in pipe; a separation plate is arranged below the feed cylinder and comprises an oblique plate A and an oblique plate B with a through hole; one end of the oblique plate A is connected with one end of the oblique plate B to form a sharp corner protruding upward; the sharp corner is positioned below the feed cylinder; and the other end of the oblique plate A and the other end of the oblique plate B are connected with the side wall of the body on the same side respectively. According to the solid-liquid separation apparatus, by increasing the dispersity of pulp and flocculating agent, the flocculating agent completely coats the pulp from inside to outside, the pulp is sufficiently mixed with the flocculating agent, and the pulp settling rate is raised.

Description

technical field [0001] The invention relates to a thickener, in particular to solid-liquid separation equipment provided with a flocculant adding device. Background technique [0002] The thickener is a solid-liquid separation device based on gravity settlement, usually a cylindrical shallow tank with a conical bottom built from concrete, wood or metal welded plates as structural materials. The ore pulp with a solid weight of 10% to 20% can be concentrated into an underflow ore pulp with a solid content of 45% to 55% by gravity sedimentation, and it can be installed in a thickener to run at a slow speed (1 / 3 to 1 / 5r / min ) rake, so that the thickened underflow slurry is discharged from the underflow port at the bottom of the thickener. [0003] The thickener speeds up the sedimentation rate of the pulp by adding a flocculant to the pulp. However, at present, the flocculant is generally mixed with the pulp in advance, and the mixed pulp is passed into the thickener, and the f...
