Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, hereinafter will be described in detail to embodiment of the present utility model by reference to the accompanying drawings.
Embodiment 1:
Present embodiments provide a kind of green silicon carbide automatic recipe maker, comprise agitator tank 4 and materials-stored box 5, in order to raw material can be made to carry out automatic mixing, the present embodiment is preferably also provided with feed mechanism, control unit PLC and driver element A and driver element B, this feed mechanism comprises at least one group of material box 1 and the weigh hopper 2 that is arranged between material box 1 and agitator tank 4 and transport tape 3, concrete set-up mode can be: the corresponding weigh hopper 2 of each material box 1, or the corresponding weigh hopper 2 of multiple material box 1, discharge port 22 correspondence of each weigh hopper 2 arranges a transport tape 3, or discharge port 22 correspondence of multiple weigh hopper 2 arranges a transport tape 3, in the present embodiment, preferably be provided with two material boxes 1 and two weigh hoppers 2 (weigh hopper 2 is corresponding with material box 1 to be arranged), two weigh hoppers 2 share a transport tape 3, see Fig. 1, it is the green silicon carbide automatic recipe maker structural representation that the present embodiment provides, material box 1 is provided with feeding port 11 and feed opening 12, in order to control the open and close of feed opening 12, at feed opening 12, place is provided with control valve 121, and this control valve 121 is any one in orifice valve, casket plate valve or butterfly valve.
In the present embodiment, weigh hopper 2 is controlled by described driver element A, and namely weigh hopper 2 receives and weighs from the raw material weight in feed opening 12, when raw material one timing, transfers to travelling belt by driver element A by the raw material in weigh hopper 2, weigh hopper 2 in the present embodiment can be the existing electronic scale with weight information collection, machinery in or electric-mechanic control system claim at least one, in order to avoid the raw material in weigh hopper 2 is revealed, and guarantee the raw material in weigh hopper 2 automatically to pour out, preferably around weigh hopper 2, be provided with blocking material plate 23, described blocking material plate 23 forms the columnar structure with opening for feed 21, described opening for feed 21 is just to the feed opening 12 of material box 1, the movable setting of at least one piece of blocking material plate 23 in blocking material plate 23, for the formation of discharge port 22, and this blocking material plate 23 is provided with elevating lever 24, described elevating lever 24 controls (preferably this driver element A is drive-motor) by driver element A, namely the lifting of elevating lever 24 is driven by driver element A, and then drive the keying of baffle plate.
