Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] This embodiment of the present invention is an aeromechanical mixing device for groundwater treatment, which mainly includes stirring blades 3 and rotating parts 2 . Among them, the stirring paddle 3 has holes on one side at the bottom, which is used for the compressed air jet. Combined with the rotation function of the rotating part 2, the gas driving force generated during the aeration of the compressed air jet can be fully utilized to realize the automatic rotation of the stirring paddle of the mixing device.

[0022] As shown in the figure, the pneumatic mechanical mixing and stirring device of the present invention is mainly composed of a stirring paddle 3 with a hole in the bottom and a rotating member 2 . Wherein the rotating part 2 is connected to the air inlet pipe 1 of the pneumatic mixing device through a bearing, and the pipe diameter...

Abstract

The invention discloses pneumatic mechanical mixing apparatus for underground water treatment. The apparatus is characterized in that the pneumatic mechanical mixing stirrer comprises an air inlet pipe which is connected with an air supply system, a stirring device which comprises a rotating part rotationally connected with the air inlet pipe, and a plurality of stirring blades which are arrangedin a radial direction with the rotating part as a center; the stirring blades are in a hollow structure; the inner space of each stirring blades communicates with the air inlet pipe; one side of the bottom of each stirring blade is provided with lateral open holes; and the hole opening directions of the plurality of stirring blades are same. The pneumatic mechanical mixing and stirring apparatus provided by the invention is suitable for the stage of underground water treatment and coagulation. The main functions of the pneumatic mechanical mixing and stirring apparatus are that on one hand, the reaction force of gas is utilized to drive the stirring paddles to rotate, so that the mixing efficiency of the underground water and a water treatment agent is improved, and on the other hand, thejet-flow action of compressed air jet is utilized, so that the underground water is in full disturbing contact with the compressed air, and thus the efficiency of the oxygenation and degassing is improved.

Description

technical field [0001] The invention relates to a pneumatic mechanical mixing device for groundwater treatment. The device is mainly used in the groundwater treatment mixing tank, and the stirring device is driven to rotate by using the high-speed gas reaction force generated during aeration. Background technique [0002] Groundwater is an important water source for urban water supply, especially in areas lacking surface water. However, because groundwater has been hidden underground for a long time, the water quality treatment method is quite different from that of surface water. Groundwater typically has low levels of turbidity and organic matter, and typically low concentrations of dissolved oxygen and correspondingly high concentrations of carbon dioxide. For this reason, groundwater treatment usually first carries out oxygenation and degassing, and then carries out subsequent treatment processes such as coagulation and sedimentation. [0003] There are many technique...
