The utility model provides a dosing device suitable for a
coal preparation
plant, which relates to the field of dosing devices and comprises a lifting device, a
water storage device is mounted at the lifting end of the lifting device, and a spray
pipe is fixedly mounted at the output end of the
water storage device. The spray
pipe can rotate under the action of a rotating piece installed on the
water storage device, the bottom of the spray
pipe is fixedly communicated with a plurality of spray heads, at least one supporting frame is fixedly installed on the spray pipe, an obliquely-arranged flow guide plate is fixedly installed on the side wall, close to the bottom end, of the supporting frame, and at least one water filtering cover is fixedly installed on the side wall of the flow guide plate. According to the chemical adding device suitable for the
coal preparation
plant, due to the fact that the flow guide plate continuously rotates,
flocculation liquid can be more easily diffused to other positions under the action of the flow guide plate, and due to the fact that the water filtering cover is arranged, the
flocculation liquid can be more easily dispersed to other positions. And more sufficient mixing can be realized.
