Description

Technical Field

[0001] The utility model relates to the field of water treatment equipment, in particular to a horizontal flow sedimentation separation device. Background Art

[0002] Sedimentation tanks are divided into horizontal flow sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The horizontal flow sedimentation tank is rectangular in shape. A horizontal flow sedimentation device is placed in the horizontal flow sedimentation tank. Wastewater flows into the tank from one end, flows horizontally through the tank, and flows out from the other end of the tank. In the prior art, there are generally two forms of horizontal flow sedimentation devices. One is a horizontal tube sedimentation separation device as disclosed in Chinese patent CN100551482C. This horizontal tube sedimentation separation device is composed of multiple sets of parallel inclined plates. When actually used, it is necessary to change the shape of the inner wall of the tank body or set a compensating body, and the installation is relatively complicated; the other is a fast horizontal flow high-efficiency sedimentation separation device as disclosed in Chinese patent CN102847349B. The sedimentation separation device disclosed in the patent is installed in the tank body without changing the shape of the inner wall of the tank body, nor does it need to set a compensating body, and the structure is compact; however, the patent also has certain defects, such as: although the mud discharge channel provided in the patent is a static liquid area, which can prevent the settled sludge from being disturbed, the mud discharge channel is the same width from top to bottom, and the sludge settles from top to bottom, which will form a blockage at the bottom. Utility Model Content

[0003] The utility model aims to provide a horizontal flow sedimentation separation device.

[0004] The innovation of the utility model is that the utility model has a compact structure, is easy to install, has high sedimentation efficiency and good effect, and can avoid clogging.

[0005] In order to achieve the above utility model purpose, the technical solution of the utility model is:

[0006] A horizontal flow sedimentation separation device comprises a plurality of sedimentation plate groups arranged in sequence, wherein the sedimentation plate groups comprise vertical plates arranged vertically, inclined plates arranged obliquely and a plurality of mud slides arranged obliquely downwardly between the vertical plates and the inclined plates in a vertical direction, wherein the plurality of mud slides are inclined upwardly along a water flow direction; a water channel is formed between adjacent mud slides; a mud slide port is arranged at the connection between the mud slide plate and the inclined plate; a lower mud channel with a smaller upper portion and a larger lower portion is formed between the inclined plate and the vertical plates of the adjacent sedimentation plate groups, wherein at least one end of each lower mud channel is closed to form a static liquid area, and the mud slide port is connected to the lower mud channel.

[0007] Furthermore, the inclination angle of the inclined plate is 80°-89°.

[0008] Furthermore, the upward inclination angle of the plurality of mud slides along the water flow direction does not exceed 10°.

[0009] Furthermore, the angles between the plurality of mudskies and the horizontal plane gradually decrease from top to bottom.

[0010] Furthermore, the distance between the plurality of mudskies decreases gradually from top to bottom.

[0011] Furthermore, the water flow area of ​​the water channel gradually decreases from top to bottom.

[0012] The beneficial effects of the utility model are:

[0013] First: the angle between the mud slide of the present application and the horizontal plane gradually decreases from top to bottom, and the lower mud channel is small at the top and large at the bottom. The upper water channel has a large water flow area, the upper mud slide has a large inclination angle, and the suspended matter slides down quickly; the lower water channel has a small water flow area, the lower mud slide has a small inclination angle, and the suspended matter slides down slightly slowly, which can effectively avoid blockage at the bottom of the lower mud channel.

[0014] Second: Along the direction of water flow, the mud slide is set obliquely upward to form a slight slope, which can improve the efficiency and effect of sedimentation.

[0015] Third: During installation, the present application does not need to change the shape of the inner wall of the pool body, nor does it need to set a compensation body. The structure is compact and easy to install. BRIEF DESCRIPTION OF THE DRAWINGS
