1. the device comprises a vacuum cavity, 2, a material suction port, 3, a storage bin, 31, a first conical body, 32, a second conical body, 4, a support lug, 5, a fan closing device, 6, a safety protection net, 7, a first material level meter, 8, a vibrator, 9, a second material level meter, 10 and a vacuum pump.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the vacuum storage bin device comprises a vacuum chamber 1, a storage bin 3 and a vacuum pump 10; the vacuum cavity 1 is communicated with the top of the storage bin 3; the air inlet end of the vacuum pump 10 is connected with the vacuum cavity 1; the upper end of the stock bin 3 is provided with a material suction port 2; the bottom of the storage bin 3 is detachably connected with a related fan 5.
The vacuum cavity 1 generates negative pressure inside the bin 3 under the vacuumizing action of the vacuum pump 10, so that the crushed materials are transferred into the bin 3 from upstream crushing machines or mixing machines and other equipment under the action of pressure difference, and the feeding process is finished; when the vacuum pump 10 stops working, namely stops sucking materials, the crushed materials in the bin 3 are continuously discharged under the action of gravity through the air shutoff machine 5 at the bottom; close fan 5 and adopt flange, bolt to be connected with feed bin 3, or link up with the help of supporting frame and fix on 3 blanking routes in feed bin to can be convenient for pull down close fan 5 clean when shutting down, be favorable to switching at the material transmission task of difference high efficiency.
A first charge level indicator 7 and a second charge level indicator 9 are respectively arranged at the upper end and the lower end of the storage bin 3; the height of the first level indicator 7 is smaller than that of the suction port 2.
The first level indicator 7 and the second level indicator 9 can adopt a mechanical design because the stacking height of the solid material is monitored, and the sensing of the material position is realized through a part such as a contact handle extending into the bin 3; specifically, when the material bin is full of materials, a signal of full material storage can be fed back as soon as the contact handle of the first material level meter 7 contacts the materials, the vacuum pump 10 is stopped, and the material bin 3 stops sucking the materials; when the material in the storage bin is about to be discharged, the contact handle of the second material level meter 9 cannot contact the material, a signal that the material does not exist can be fed back at the moment, the vacuum pump 10 starts to work again, and the storage bin 3 can continue to suck the material.
The lower end of the stock bin 3 is provided with a first conical body 31 in a contracting way along the direction of reducing the height; the first conical body 31 is provided with a vibrator 8.
The shrink profile of first conical body 31 is favorable to letting the crushing material fully assemble and fall to 3 bottoms of feed bin, avoids the remaining difficult problem of clearance of edge department material that the level bottom leads to, and vibrator 8 then can promote its removal through the vibration effect to the relatively poor material of mobility, lets material transmission more smooth.
A stainless steel filter element is arranged in the vacuum cavity 1.
Stainless steel filter core can be used for adsorbing and leads to the dust that gets into 3 insides in feed bin along with smashing material, can protect vacuum pump suction channel on the one hand not blockked up, and on the other hand also can play the material purification effect, promotes the quality of closing the 5 ejection of compact of fan.
The top of the storage bin 3 is provided with a second conical body 32 in a contracting manner along the height increasing direction; the vacuum pump 10 is connected and arranged at the top end of the second conical body 32; the material suction port 2 is arranged on the conical surface of the second conical body 32.
The contraction structure of the second conical body 32 can adapt to the caliber change of the vacuum cavity, so that light suspended impurities such as dust move upwards along with the airflow and are collected and finally adsorbed by the stainless steel filter element; simultaneously, the conical surface also can play certain effect of blockking to the crushing material that just got into 3 insides in feed bin in vertical direction, and the inside cross-section that expands from the top down also can suitably weaken the suction of inhaling material mouth 2 tops, avoids crushing material and dust to drift upward together and blocks the air flue.
The lower end of the air-lock valve 5 is provided with a safety protecting net 6; the safety protection net 6 is internally provided with a # -shaped grid.
The safety protection net 6 has the advantages that accidental injury caused by mistakenly inserting hands of operators or visitors or equipment damage caused by inserting instruments into the safety protection net can be avoided, and production safety is improved. The grid is favorable for the material to uniformly pass through the safety protection net 6 and fall.
The outer surface of the storage bin 3 is annularly provided with a plurality of supporting lugs 4.
The hangers 4 can be supported by the frame body or matched with the frame body in an installing mode and used for fixing the storage bin.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
