Abstract
The utility model relates to a jet delivery pump which transports powdery material with air force. The pump is composed of a bawke, a delivery pump and a jetting tube which are installed on the lower part of the bawke. Upright structure is adopted in the delivery pump, a jetting device is installed at the delivery outlet of the utility model. The utility model, compared with existing jet delivery pump, has features of big feed inlet, continuous and even charge-in and feeding, big internal pressure of the discharge nozzle and strong jetting force of aspiration. The utility model can effectively prevent the phenomenon of local blocking and jet intermittent in transportation of powder material, and it improves the evenness and constancy of jetting discharge. The jump is especially suitable for matching with a spray agitation drilling machine, which can advance the construction quality of powder body jet agitation method.
Description
The utility model relates to and a kind ofly comes the injection transmission pump of conveying powder material with strength, is particularly suited for and the Spray agitation drilling machine configuration is used.
Powder spray mixing method is a present new reinforced soft soil ground technology, Spray agitation drilling machine is a specialized equipment of implementing powder spray mixing method, in Spray agitation drilling machine, be provided with the injection transmission pump that is used for carrying with jet cement and lime, this sprays transmission pump usually by batch can, transmission pump, formations such as jet pipe, because transmission pump adopts horizontal type structure, inlet point is less, the conveying of powder ash and injection are mainly finished by jet pipe, therefore, be easy to occur uneven material feeding in actual use, get stuck and local situation about stopping up, cause producing the interruption of feeding and not smooth, influence the construction quality of powder spray mixing method.
Task of the present utility model is to avoid above-mentioned weak point and provides a kind of charging continuous controllable, feeding evenly smooth injection transmission pump.
Task of the present utility model is realized by following basic scheme: have a batch can 1, transmission pump 6 is equipped with in the batch can bottom, the equipped at outlet port of transmission pump is installed on jet pipe 5, its difference is that transmission pump 6 is vertical structure, also is installed on an eductor 9 that is connected with discharge nozzle 2 at the transmission pump equipped at outlet port.
According to such scheme, during work, powder in the batch can via the driving of impeller, is sent to powder the delivery port 23 of transmission pump because of the effect of deadweight and jar internal gas pressure falls in the impeller of transmission pump, under the effect of jet pipe 5, powder is sent to blending box 20, at this moment, because the injection of eductor 9 high speed steam flows, make powder and air-flow mix and be sent into rapidly together diffuser pipe 24 mutually, powder is ejected via the discharge nozzle that links to each other 2.Major advantage of the present utility model is: one, transmission pump has adopted vertical structure, make the inlet point of transmission pump increase, more than half annular space of impeller becomes the inlet point of transmission pump, so be easy to make it to be full of a jar interior powder, avoid getting stuck and the generation of discontinuity feeding situation, can control the inlet amount of spraying transmission pump easily by the adjusting of wheel speed, and the continuity of charging feeding and homogeneity also directly influence spray the homogeneity and the stability of discharging; Second, the utility model is on the basis of original jet pipe 5, equipped at outlet port at transmission pump has also been set up an eductor, adopt this structure, can make the speed kinetic energy of jet-stream wind convert pressure to can make the pipe internal pressure further increase, the suction jet power of complete machine also further strengthens, thereby can prevent the phenomenon generation that local obstruction, injection are interrupted in the powder conveying effectively, and the homogeneity that can make complete machine spray discharging is further improved.
Fig. 1 is the overall construction drawing of an embodiment of the utility model, and the figure sharp head is represented the flow direction of air-flow and powder.
Fig. 2 is the main cutaway view of transmission pump among embodiment of the utility model.
Fig. 3 is the birds-eye view of Fig. 2.
Fig. 4 is the cutaway view of the utility model eductor.
Embodiment of the present utility model such as Fig. 1,2,3, shown in 4, has a leak free batch can 1, the batch can top is connected with air inlet pipe 3, be equipped with transmission pump 6 in the bottom of batch can, transmission pump is a vertical structure, the driver train 7 of the second line of a couplet one variable-ratio, the equipped at outlet port of transmission pump 6 is provided with jet pipe 5, carry pump structure such as Fig. 2, shown in 3, has the pump housing pump housing 15 that is connected with batch can 1, in be equipped with impeller 13, impeller connects firmly mutually with transmission shaft 12,11 is pressing plate, transmission shaft 12 is supported by two bearings 18 up and down, bearing can be selected sealed bearings for use, and install gland 17 and seal cover cap 19 and configuration seal ring 16 at their two ends, be installed on blade 14 on the periphery of impeller 13, a conical top cover 10 can be equipped with in the upper end of impeller 13, one side of impeller 13 is provided with delivery port 23, its upper end is equipped with fan-shaped seal cover cap 21, can make transmission pump delivery port 23 and batch can keep better seal and isolation like this, and help to control more easily the feeding amount of transmission pump, joint 22 is connected with helping spirt tracheae 5, be installed on an eductor 9 below delivery port 23, eductor 9 is by case of sprayer 26, nozzle 25 and diffuser pipe 24 constitute, and wherein case of sprayer 20 is connected with the delivery port 23 of transmission pump, nozzle 25 is connected with air inlet pipe 9, the mouth of diffuser pipe 24 then is connected with discharge nozzle 2, in addition, and in order to realize continuously weighing measurement monitoring, can be at the arranged outside pulling force sensor 4 of batch can 1, so that show and control.Present embodiment mainly is suitable for and the Spray agitation drilling machine phase configuration, can make powder via drilling rod and evenly ejection effectively of drill bit.
