Problems solved by technology

[0003] At present, in the water treatment process, most of the sediments are filtered through layers of screens, or multi-stage sedimentation is used to achieve solid-liquid separation. With the above two methods, on the one hand, multi-stage sedimentation will take up more space. Screen filtration, because the sediment is more fragile, especially through flocculation, the sediment is even more fragile, so the filtering effect is not good, so the solution to save energy, not occupy space, and the solid-liquid separation device with good solid-liquid separation effect has become the current Insurmountable Technical Difficulties

Embodiment 1

[0026] Such as Figure 1-4 As shown, a solid-liquid separation device includes a sedimentation tank 1, an inlet pipe 11 is arranged on one side of the sedimentation tank 1, and an outlet pipe 12 is arranged on the other side, and a sewage discharge pipe 13 is arranged on the bottom of the sedimentation tank 1. A solid-liquid separator 2 is provided below the water inlet pipe 11, and the water inlet pipe 11 is set as a three-way pipe, so that the incoming water flow will be divided into two water flows, and the bottom of the solid-liquid separator 2 is oppositely provided with a first water pipe 111 and the second water pipe 112, because the two are oppositely arranged, so when the water flows out from the two outlets, convection will be formed. The first and second water pipes are connected with the water inlet pipe, and the two are oppositely arranged. The centers of the first water pipe 111 and the second water pipe 112 are not on the same straight line, the two are not on t...

Embodiment 2

[0028] Such as Figure 1-2 As shown, the same parts of this embodiment and Embodiment 1 will not be repeated, and the difference is:

[0029] The sloping plate part 22 is set as a right-angled triangular plate, and the plate of this shape is more conducive to pushing and rotating by means of the gravity of water. The long right-angled side of the sloping plate part 22 is arranged outside the main shaft 25 and is parallel to the axis of the main shaft 25 , which is designed to allow the hypotenuse of the triangle to contact the water to form a thrust. The swirl part 23 is arranged below the short right-angled side of the swash plate part 22, so that when the water drives the swash plate part 22 to rotate, it drives The swirl part 23 rotates to form a vortex at the bottom to improve the efficiency of solid-liquid separation, and the width of the swirl part 23 is 1 / 4-1 / 2 of the short right-angled side. This design can meet the requirements of the solid-liquid separator. 2 The vo...

Abstract

The invention discloses a solid-liquid separation device which comprises a sedimentation tank. A water incoming pipe is arranged above one side of the sedimentation tank, a water outgoing pipe is arranged below the other side of the sedimentation tank, a blow-off pipe is arranged at the bottom of the sedimentation tank, a solid-liquid separator is arranged below the water incoming pipe, a first water pipe and a second water pipe are arranged at the bottom of the solid-liquid separator oppositely and communicated with the water incoming pipe, and centers of the first water pipe and the second water pipe are not on a same straight line; a separation portion is arranged in the solid-liquid separator, stabilizing portions are arranged above and below the separation portion, a spindle penetrates the stabilizing portions, circumferential rotating direction of the spindle in the stabilizing portions is unlimited, a cant board portion is arranged on the spindle and provided with a triangular board, a whirling portion is arranged below the cant board portion, and the first water pipe, the second water pipe and the whirling portion are arranged in a same plane. The solid-liquid separation device has the advantages of small occupied space, quickness in flocculation and conservation of energy sources.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a solid-liquid separation device. Background technique [0002] my country's urban sewage treatment plants or electroplating sewage need to be purified, and flocculants play a very important role in wastewater treatment. heavy metals and radioactive substances. [0003] At present, in the water treatment process, most of the sediments are filtered through layers of screens, or multi-stage sedimentation is used to achieve solid-liquid separation. With the above two methods, on the one hand, multi-stage sedimentation will take up more space. Screen filtration, because the sediment is more fragile, especially through flocculation, the sediment is even more fragile, so the filtering effect is not good, so the solution to save energy, not occupy space, and the solid-liquid separation device with good solid-liquid separation effect has become the current Insurmountable technic...
