Abstract
The utility model disclose a foundry sand crushing and loosening device which comprises a case body mounted on a support frame; a crushing shaft is rotatingly mounted in the case body and rotates in an opposite direction; intermeshed crushing teeth are distributed on the crushing shaft in a radial direction; a support frame is disposed on opposite side walls of the case body; a feed hopper is mounted on the support frame; a vibrator is disposed on the outer wall of the feed hopper; a discharge port of the feed hopper is a flat port; the discharge port is located right above the meshing line of the crushing teeth of the crushing shaft; a vibrating screen is disposed below the discharge port. The device of the utility model is simple in structure design, can optimize procedures, and is less in space and resource occupation; material feeding of the feed hopper is cooperated by the intermeshed crushing teeth; the device has good feeding persistence, and can conveniently and rapidly crush materials; in addition, the vibrating screen loosens the crushed materials, which improves processing efficiency.
Description
Technical field:
The utility model relates to the molding sand process technology, relates in particular to a kind of casting model powder and pulverizes and aeration apparatus.
Background technology:
Molding sand is to be used for the material of moulding in sand casting.Molding sand is generally mixed according to a certain percentage by casting model powder, moulding sand binder and the auxilliary Modeling Material such as thing that adds, also available natural silica sand argillaceous.The effect of molding sand in Foundry Production is very important, and the casting wasted product that causes because of the poor quality of molding sand accounts for 30～50% of the total waste product of foundry goods.
For the casting model powder of one of molding sand raw material, wherein some large particulate matter is more, need carry out fragmentation, also needs to carry out loose processing after the fragmentation, and originally broken and loose is two different operations, so working (machining) efficiency is low relatively, and hand labor intensity is big.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of casting model powder and pulverizes and aeration apparatus, and structural design is simple, can improve the efficient of processing quickly and easily with the fragmentation of molding sand material and loose processing.
The technical solution of the utility model is as follows:
Casting model powder is pulverized and aeration apparatus, comprise the casing that is installed on support, it is characterized in that: be rotatablely equipped with the broken shaft that rotates in opposite directions in the described casing, the broken shaft upper edge is radially distributed with intermeshing crushing teeth, and the sidewall that described casing is relative is provided with bracing frame, and feed hopper is installed on the bracing frame, the outer wall of feed hopper is provided with vibrator, the discharging opening of feed hopper is flat mouthful, and discharging opening is positioned at directly over the crushing teeth path of contact of broken shaft, and the discharging opening below is provided with vibratory sieve.
Described casting model powder is pulverized and aeration apparatus, and it is characterized in that: the bottom of described casing is provided with the feed opening of taper.
The utility model has the advantages that:
The utility model structural design is simple, has optimized operation, and the resource that takes up room is few, fit into the charging of hopper by intermeshing crushing teeth, the charging continuation is good, can conveniently material be carried out fragmentation, in addition, vibratory sieve carries out loose to the material of fragmentation, has improved the efficient of processing.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1:
Casting model powder is pulverized and aeration apparatus, comprise the casing 2 that is installed on support 1, be rotatablely equipped with the broken shaft 3 that rotates in opposite directions in the casing 2, broken shaft 3 upper edges are radially distributed with intermeshing crushing teeth 4, and casing 2 relative sidewalls are provided with bracing frame, and feed hopper 5 is installed on the bracing frame, the outer wall of feed hopper 5 is provided with vibrator 6, the discharging opening of feed hopper 5 is flat mouthful, and discharging opening is positioned at directly over crushing teeth 4 path of contacts of broken shaft 3, and the discharging opening below is provided with vibratory sieve 7.
The bottom of casing 2 is provided with the feed opening 8 of taper.
