Ferric chloride coagulating agent uniform sprinkling device for sedimentation tank

Abstract

The invention relates to a ferric chloride coagulating agent uniform sprinkling device, in particular to a ferric chloride coagulating agent uniform sprinkling device for a sedimentation tank. The technical problem to be solved by the invention is to provide the ferric chloride coagulating agent uniform sprinkling device for the sedimentation tank, which is uniform in sprinkling, time-saving and labor-saving, and high in sprinkling speed. In order to solve the above technical problem, the ferric chloride coagulating agent uniform sprinkling device for the sedimentation tank, provided by the invention, comprises a sedimentation tank, fixed plates, a slide rail, a first sliding block, a transverse plate, a second sliding block, a connecting plate and the like, wherein the fixed plates are arranged symmetrically at the tops of the left and right sides of the sedimentation tank, the tops of the fixed plates are connected with the slide rail in a bolted connection mode, and the first sliding block is connected to the slide rail in a sliding mode. By virtue of left-right movement of the connecting plate, and backward stirring of the first sliding block by a worker, the ferric chloride coagulating agent uniform sprinkling device provided by the invention performs sprinkling comprehensively on the sedimentation tank, thereby achieving the effects of being uniform in sprinkling, time-saving and labor-saving, and high in sprinkling speed.

Description

technical field [0001] The invention relates to a device for uniformly sprinkling ferric chloride coagulant, in particular to a device for uniformly sprinkling ferric chloride coagulant for a sedimentation tank. Background technique [0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. Sedimentation tanks are widely used in wastewater treatment. It has many types, which can be divided into three types: advection type, vertical flow type and radial flow type according to the direction of water flow in the pool. Considering the flocculation factor in the process of particle settling, it is assumed that the settling velocity of the particles changes at constant acceleration, and the initial settling velocity is set to zero. Considering the flow velocity distribution in the tube, the length of the inclined tube is: -d*tgθ where a is the acceleration of particle sinking velocity change, that is, a=du / dt The above three methods ha...

Problems solved by technology

[0005] The present invention overcomes the shortcomings of sprinkling ferric chloride coagulant in the sedimentation tank manually at present, thus there is uneven sprinkling, it takes a lot of time and energy for people, and the sprinkling speed is slow. The technical problem is to provide a device for evenly sprinkling ferric chloride coagulant for sedimentation tanks, which saves time and effort, and has a fast sprinkling speed.
