Technical Field

The utility model relates to a mechanical equipment especially relates to the mechanical equipment device that tombarthite waste material carries out breakage and screening.

Background

At present, because rare earth waste materials for recycling and processing contain more blocks, the rare earth waste materials are generally crushed and screened before being dried and dehydrated (roasted), so that the drying efficiency is improved, the energy for drying is saved, and good conditions are provided for improving the dissolution of rare earth elements in the next procedure. Some of the conventional rare earth waste materials are crushed and screened separately, so that the method has the disadvantages of large occupied area, more operators, low production efficiency and high production working hour cost; some crushing and screening are combined into a whole, but the structure is more complex, the manufacturing time and cost are high, and the maintenance is not convenient.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the above-mentioned prior art, the utility model provides a device that not only simple structure is compact, makes and uses, maintains the convenience, again can the breakage can sieve to the tombarthite waste material.

The to-be-solved technical problem of the utility model is that: the utility model provides a tombarthite waste material crushing and screening device, it includes the main frame, be provided with the pivot through the bearing frame on the main frame, the fixed spoke that is provided with in pivot both ends, the spoke that is located the left end with be that annular main tributary vaulting pole one end is fixed to be continuous, the spoke that is located the right-hand member with be that annular auxiliary stay pole one end is fixed to be continuous, the fixed layer board that is provided with between corresponding main tributary vaulting pole and the auxiliary stay pole, be provided with the stainless steel screen cloth with the screw rod is fixed on the layer board, the interval is provided with the outer crushing pole that is the closed angle towards the pivot direction on the layer board, the distance is 30-50 millimeters between outer crushing pole pointed end and the helical

The interval is provided with the interior broken pole that is the closed angle towards the pivot direction on the helicoid, the stainless steel screen cloth exocoel is provided with both ends confined urceolus, urceolus both ends face and stainless steel screen cloth terminal surface parallel and level, be provided with the screening feed opening on the urceolus main aspects, the interval is equipped with the connecting plate in the screening feed opening, be provided with the loading hopper that is close to the little terminal surface of stainless steel screen cloth in the auxiliary frame, be provided with the blown down tank that is close to the big terminal surface of stainless steel screen cloth on the main frame.

The cross section of the stainless steel screen is circular or regular hexagon.

The tombarthite waste material that contains the lump material get into in the stainless steel screen cloth from the loading hopper, wherein the lump material becomes the suspension form under helical blade's constantly stirring is broken, owing to received the interact that is the inside and outside broken pole of netted distribution again in the suspension rolls, cubic tombarthite waste material is in order to break into the powder, the powder gets into in the urceolus and flows from rotatory feed opening through the roll screening.

The utility model discloses utilize multipurposely rotatory helical blade has the function of breakage, stirring and transport, again through the extrusion of the interior broken pole on the outer broken pole that sets up on the layer board and the helical blade, organically combine into an organic whole with crushing and screening and transport to simplify crushing and screening all-in-one structure, both reduced and taken area and operating personnel, improved production efficiency again, reduced production man-hour cost.
