According to the discharging device, the air lock discharging valve is removed, the supplied material slag is directly fed at the upper end of the middle chute pipe, the occupied area of the equipment is reduced, the device is simple in structure and convenient to maintain, the discharging device can realize automatic air lock, the mill cost is reduced, and the device is suitable for wide-range popularization and application.
Description
Technical field
The utility model relates to a kind of blanking device, and specifically a kind of slag vertical roll grinder is with independently locking the wind blanking device.
Background technology
Tradition slag vertical roll grinder top is provided with the lock wind baiting valve that plays lock wind and two effects of blanking, material is fallen by lock wind baiting valve, fall into straight down emission of baiting chute through having the middle elephant trunk that is flexible coupling, directly fall on the baffle plate of mill middle, the mill rotation is thrown to material the milling zone of mill circumferencial direction, grind through mixing roll, finished product is selected away by the powder concentrator on grinding machine top, semi-finished product are blown off the formation cycle stock by material scraping plate, enter again in the mill from the cycle stock entrance, grind, select powder again.Lock wind baiting valve is pneumatic mechanism; the making assembly precision is higher; about 100,000 yuan of cost; in the use; because system situation complexity in the mill is negative pressure in the normal condition mill, if dust collecting fan is unusual or grinding machine has air leakage phenomena; cause grinding machine inside to become malleation; fine powder or half-fine powder move on emission of baiting chute easily, mix with the supplied materials breeze, add that breeze contains certain moisture; the thickness material is bonded on lock wind blanking valve housing and the valve plate together; cause the valve plate switch not smooth, blanking is obstructed, and is difficult to cleaning; influence the operate as normal of grinding machine, even cause and stop mill.
The utility model content
The utility model is at the existing defective of lock wind baiting valve in the existing blanking device, and a kind of independently lock wind blanking device of slag vertical roll grinder that the difference in height of locking the wind baiting valve, passing through middle part cone and emission of baiting chute lower limb realizes autonomous lock wind that removes is provided.
The technical scheme that realizes the employing of foregoing invention purpose is: a kind of slag vertical roll grinder is with independently locking the wind blanking device, elephant trunk, middle part cone, emission of baiting chute, mill baffle plate, vertical scraper and grinding roller milling zone in the middle of comprising; The lower cylindrical section concentric locking collar of described middle part cone is loaded on the emission of baiting chute outside, the lower limb of middle part cone is lower than the lower limb of emission of baiting chute, the mill baffle plate be arranged on the middle part cone under, the excircle of mill baffle plate is the grinding roller milling zone, the top of mill baffle plate is provided with vertical scraper, and the upper end of described middle elephant trunk is the supplied materials entrance; The lower limb of described middle part cone and emission of baiting chute and same vertical plane constitute an intersection point respectively, and the angle that the connecting line of two intersection points and horizontal plane constitute is the natural angle of repose of breeze material.
The lower limb of this angle by middle part cone and emission of baiting chute is to the realization that matches of the height of mill baffle plate.
Compare with traditional blanking device, this novel disclosed this blanking device has removed the lock wind baiting valve that is installed in the top, the supplied materials slag is directly by the last endfeed of middle elephant trunk, reduce occupation area of equipment, simple in structure, maintain easily, only need the ability according to actual grinding machine, the kind of material, the difference in height of elephant trunk and middle part cone lower limb in the middle of factors such as the moisture of material are determined, the lower limb of the two and same vertical plane have an intersection point respectively, the connecting line of two intersection points and horizontal plane structure are the natural angle of repose of material in an angle, can make blanking device realize autonomous lock wind, reduce the grinding machine cost, suitable for large-scale promotion and use.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Among the figure: middle elephant trunk 1, middle part cone 2, emission of baiting chute 3, mill baffle plate 4, grinding roller milling zone 5, vertically scraper 6.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
This slag vertical roll grinder comprises middle elephant trunk 1, middle part cone 2, emission of baiting chute 3, mill baffle plate 4, vertical scraper 6 and grinding roller milling zone 5 with autonomous lock wind blanking device.Wherein: the lower cylindrical section of middle part cone 2 and emission of baiting chute 3 concentric suits, and the upper-lower position of the two all can adjust, and the lower limb of middle part cone 2 is lower than the lower limb of emission of baiting chute 3.Mill baffle plate 4 be arranged on the middle part cone 2 under, mill baffle plate 4 is positioned at the centre of whole mill, the excircle of mill baffle plate 4 is grinding roller milling zone 5, the excircle of the top of mill baffle plate 4, middle part cone 2 is provided with vertical scraper 6.
The upper end of middle elephant trunk 1 is the supplied materials entrance, and the supplied materials slag is directly entered in the whole blanking device by the upper port of middle elephant trunk 1.Middle part cone 2 is sleeved on the outside of emission of baiting chute 3, the lower limb of middle part cone 2 and emission of baiting chute 3 is respectively two parallel circles up and down, these two circles and same vertical plane can constitute an intersection point respectively, as the point of a among Fig. 1 and b point, the angle that the connecting line of two intersection points and horizontal plane constitute is angle A, angle A in the present embodiment is 35 °, and the angle of this angle equates with the natural angle of repose of breeze material.
The lower limb of included angle A by middle part cone and emission of baiting chute is to the height H 1 of mill baffle plate and the H2 realization that matches.In practical operation, the kind of known material just can be determined the number of degrees of the natural angle of repose of material certainly; Determine earlier that by the ability of grinding machine, the moisture content of material and the factors such as weight of material the lower limb of emission of baiting chute is to the height H 1 of mill baffle plate, then through angle comparison and debugging repeatedly, determine middle part cone lower limb to the height H 2 of mill baffle plate by the position of adjusting the middle part cone, thus the blanking work that wind can be independently locked in realization.Corresponding different situations are determined concrete parameter in the debug process, and record numerical value, make the grinding machine of various seriations all preserve fixing desired quantity.
