Backflow-type multistage sorting pulping machine

Abstract

The invention discloses a backflow-type multi-stage sorting pulping machine. The pulping machine comprises a bearing bottom frame, a horizontally-arranged mixing barrel is rotationally installed above the bearing bottom frame, a feeding hopper is arranged at one end of the mixing barrel, a screening barrel is arranged at the other end of the mixing barrel, a driving motor for driving the mixing barrel to rotate is arranged on the bearing bottom frame, a material distributing hopper is arranged below the screening barrel, a first screening plate and a second screening plate which are obliquely arranged are sequentially arranged in the material distributing hopper from bottom to top, a liquid collecting tank is arranged below the material distributing hopper, a backflow pipe is arranged on the outer wall of the liquid collecting tank, and a backflow pump is installed on the backflow pipe. The pulping machine has the beneficial effects that: gravel in slurry is sorted by adopting the structure that the screening barrel is matched with multiple stages of screening plates, grading of the gravel can be achieved, and classified storage is facilitated; and by adopting a backflow design, the sand and stones which are not completely filtered in the slurry can be repeatedly filtered, so that the sorting quality of the gravelin the slurry is ensured, and the filtering precision is improved.

Description

technical field [0001] The invention relates to the technical field of mineral separation equipment, in particular to a backflow type multi-stage separation pulping machine. Background technique [0002] In the process of ore separation and collection, it is usually necessary to separate the ore and sediment in the raw materials. The equipment used in traditional separation processing is mostly a pulper, and the sand mixed with water is put into the drum for mixing and stirring, so that Mix the lighter silt inside the sand into a slurry, and finally discharge the slurry to separate the ore. However, the main problem of this type of pulping machine is that the sieving accuracy is not enough, and the sand mixed in the slurry cannot be screened. Grading and screening is easy to waste materials, which requires subsequent processing, which increases the cost of sorting and is not practical enough. Contents of the invention [0003] The purpose of the present invention is to pr...
