Abstract
The utility model discloses a cement mixing device for coal mine ground grouting. The cement mixing device comprises a material mixing cavity, wherein a charging hole is formed in the upper end of the material mixing cavity; a discharging hole is formed in the lower end of the material mixing cavity; a continuous turn-back type mixed material channel is formed in the material mixing cavity and is positioned between the charging hole and the discharging hole; a water inlet is formed in the upper end of the material mixing cavity; a material pull-out hole is formed in the wall of the material mixing cavity and is positioned at a turn-back place of the mixed material channel; and a movable door is arranged on the material pull-out hole. According to the cement mixing device, cement ash is mixed with water in an S-shaped closed material mixing cavity channel, so that the mixing time of cement and the water is prolonged, and the mixing path of the cement and the water is increased. The cement and the water can be well mixed through repeated turn-back, the cement waste caused by inadequate mixing is reduced, and the environmental dust is reduced.
Description
Technical field:
The utility model relates to a kind of coal mine ground grouting equipment, particularly relates to a kind of coal mine ground grouting cement mixing device.
Background technology:
In coal mine ground slip casting process, cement need by the strand cage in the jar down to feed opening, the flushing by water under high pressure is mixed into cement grout, flow to and mixes slurry in the stirring pool.In this process, cement dust flies away out at the feed opening place, not only wasted cement raw material, cause simultaneously and do industry environment non-constant, operating personnel's respiratory health is had serious threat, operating personnel must wear anti-dust respirator could normal operating, but also can impact healthy, and the environment dust is excessive, and visibility reduces, and staff's operation is very inconvenient.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to use, compounding effect is good and reduce the coal mine ground grouting cement mixing device of dust from flying.
The technical solution of the utility model is: a kind of coal mine ground grouting cement mixing device, contain the batch mixing cavity, described batch mixing cavity upper end is provided with charging aperture, described batch mixing cavity lower end is provided with discharging opening, be provided with continuous Zigzag type compound passage in the described batch mixing cavity between described charging aperture and the discharging opening, described batch mixing cavity upper end is provided with water inlet.
Arrange on the described batch mixing cavity body wall at the described compound passage place of turning back and draw the material mouth, and the described material mouth of drawing is provided with dodge gate.
Be provided with at least one hang plate in the described batch mixing cavity, between described hang plate and the described batch mixing cavity, form the compound passage respectively between the adjacent described hang plate.
Be provided with three described hang plates in the described batch mixing cavity, form between described updip swash plate and the batch mixing cavity and go up the compound passage, compound passage in forming between described updip swash plate and the medium dip plate, described medium dip plate and the following compound passage of formation between the swash plate that has a down dip, the described outlet of compound passage down is described discharging opening.
The beneficial effects of the utility model are:
1, the utility model mixes concrete grey with water in serpentine sealing batch mixing cavity, prolonged the incorporation time of cement and water, increased the distance that cement and water mix, because through turning back several times, thereby the degree of mixing of cement and water is good, reduce the cement waste that causes because of undercompounding, reduced the environment dust simultaneously.
2, the utility model is drawn the material mouth the batch mixing cavity body wall setting at the compound passage place of turning back, and draws and expect that mouth is provided with dodge gate, if cement mortar blockage phenomenon in the batch mixing cavity can be opened dodge gate and remove clinker, uses very convenient.
3, the utility model compound passage can be arranged to toroidal, and the horn mouth direction of adjacent compound passage can be opposite, can regulate the flowing velocity of cement mortar automatically, the mixability that can also regulate cement mortar.
4, in the utility model batch mixing cavity a plurality of hang plates are set, are convenient to form a plurality of compound passages, change the angle of hang plate, can change the flowing velocity of whole cement mortar, also be convenient to maintenance in addition, reduce maintenance cost.
5, the utility model is simple in structure, easy to use, compounding effect is good and reduce dust from flying, and it is applied widely, particularly is applicable to the cement mixing of colliery slip casting, is easy to promotion and implementation, has good economic benefit.
Description of drawings:
Fig. 1 is the structural representation of coal mine ground grouting cement mixing device.
The specific embodiment:
Embodiment: referring to Fig. 1, among the figure, the 1-swash plate that has a down dip, compound passage under the 2-, 3-batch mixing cavity, 4-medium dip plate, compound passage among the 5-, 6-updip swash plate, the last compound passage of 7-, 8-charging aperture, 9-water inlet, 10-dodge gate, 11-are drawn material mouthful.
Coal mine ground grouting cement mixing device contains batch mixing cavity 3, wherein: batch mixing cavity 3 upper ends are provided with charging aperture 8, batch mixing cavity 3 lower ends are provided with discharging opening, be provided with continuous Zigzag type compound passage in the batch mixing cavity 3 between charging aperture 8 and the discharging opening, batch mixing cavity 3 upper ends are provided with water inlet 9.
Arrange on batch mixing cavity 3 body walls at the compound passage place of turning back and draw material mouth 11, and, draw material mouth 11 and be provided with dodge gate 10.
Concrete, be provided with three hang plates in the batch mixing cavity 3, form between updip swash plate 6 and the batch mixing cavity 3 and go up compound passage 7, compound passage 5 in forming between updip swash plate 6 and the medium dip plate 4, medium dip plate 4 and the following compound passage 2 of formation between the swash plate 1 that has a down dip, the outlet of following compound passage 2 is discharging opening.
During work, cement is entered by charging aperture 8, and press water is entered by water inlet 9, flowing in cement and mixing limit, pressure waterside, through turning back several times, guarantees that cement fully mixes with water, if cement mortar blockage phenomenon in batch mixing cavity 3 can be opened dodge gate 10 and remove clinker.
The above only is preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction, and any simple modification that every foundation technical spirit of the present utility model is done all still belongs in the scope of technical solutions of the utility model.
