Abstract
The utility model relates to a pulp spraying machine, which is characterized in that an air pressing pipe on a rotor which is provided with a hopper in a rotor mechanism is arranged on the lower part of the hopper; a pulp discharging port on the upper part of the rotor mechanism is square and is communicated with the air pressing pipe. The utility model has the advantages that the damage of the friction plate caused by abrasion is reduced, the consumption of the electric power caused by friction is reduced, air leakage and pulp leakage are controlled, and air pollution underground is reduced through the improvement of the existing pulp spraying machine.
Description
Technical field
The utility model relates to one of the equipment in tunnelling construction pulp shooting machine.
Background technology
Pulp shooting machine is one of visual plant in the tunnelling construction.The pulp shooting machine of China's production and use to the PV-5C type, has a variety of from the ZP-V type.But all there is a serious problem in these pulp shooting machines in producing use, be exactly that its friction board very easily damages, and cause and run wind race material.That runs that wind runs that cement dust that material produces gives the worker has healthyly brought serious harm; The damage of friction board has then increased cost of production and maintenance load.Trace it to its cause, mainly be that the pressure ventilation pipe Position Design is unreasonable on the rotor mechanism, for ZP-V type pulp shooting machine, under the sealing of rubber mill wiping board, the dust and sand that blows afloat is difficult to ejection, major part is attached on the rubber tile by blast, and when rotor mechanism continued rotation, these dust and sand just embedded in the gap of friction board and rotor mechanism bonding surface.Here it is causes friction board and rotor mechanism wear damage, is to cause running the most important reason that wind runs material.For PV-5C type pulp shooting machine, it adopts friction sealing plate and end friction board all to seal in the totally enclosed mode of 360 degree, the result causes having increased the load of motor having produced bigger frictional resistance between rubber mill wiping board and rotor mechanism up and down, has consumed a large amount of electric energy.Simultaneously, also fail to stop the phenomenon of running wind race material.
Summary of the invention
Run wind race material, friction board and rotor mechanism wear problem in order to solve, the utility model provides a kind of pulp shooting machine that improves mechanism.
This pulp shooting machine comprises motor, reduction box, material toggling dish, air line, conveying pipeline road, rotor mechanism, discharging elbow and sealing friction board, and it is characterized in that: on the rotor with hopper of rotor mechanism, its pressure ventilation pipe is located at the bottom, side of hopper.
Described pressure ventilation pipe is located at the nearly rotor cylindrical of hopper side lower part Monday.
The discharging opening on rotor mechanism top is square, is being communicated with pressure ventilation pipe.
The friction board top on rotor top is provided with the spring compression mechanism that comprises spring and briquetting.
The utility model has changed the position of pressure ventilation pipe, the shape of discharging opening by the improvement to existing pulp shooting machine, has reduced the whitewashing material that adheres on the friction board effectively, having reduced the damage of the friction board that wearing and tearing cause, and the power consumption that causes because of friction; Simultaneously, even if the pressure ventilation pipe mouth does not press tightly, also can only run wind and material can not occur running, the caulking gum of pressure ventilation pipe mouth is required needn't be excessive.
Be under control owing to run wind race material, significantly reduced the air pollution of down-hole.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the rotor mechanism structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Referring to Fig. 1, Fig. 2, this pulp shooting machine comprises motor 1, gear-box 2, air line, pressure ventilation pipe friction board 3, rotor mechanism, discharging opening 9, loading bin 4, sieve sieve 10 and accelerating admixture hopper 11.
Rotor mechanism 6 has on the rotor of square hopper 5, and its pressure ventilation pipe 12 is located at square hopper 5 nearly rotor cylindrical side lower parts Monday, and with square hopper 5 at an angle.The discharging opening on rotor mechanism 6 tops is square, with the wall thickness between discharging opening before and after reducing, the also wearing and tearing that can reduce friction further and cause; Its corner is equipped with the pressure ventilation pipe 12 that is being communicated with air line, and press the wind direction consistent with the discharging opening direction, make its below form negative pressure, this can be avoided material is blown in the back hopper 5, some surplus ashes can also be sucked discharging opening 9 by force, guarantee that whitewashing is expected uniformly, injection continuously.
Air line is divided into two-way, and one the road is connected to pressure ventilation pipe 12 places of the square hopper bottom of rotor, and another road is connected to pressure ventilation pipe 12 places on the discharging opening.
Friction board 7 tops on rotor top are installed with the spring compression mechanism 8 that comprises spring and briquetting.
After this pulp shooting machine entered duty, wind divided two-way to enter square hopper 5 and discharging opening 9 respectively from air line.
