On this feeding tube 10, in this feed pump 20 rear end and before the first and second discharge nozzle 30,40, be provided with ball adding device 70 so that a spheroid 80 is pushed in feeding tube 10.This feeding tube 10 is pipe, and the diameter of this spheroid 80 equates with the internal diameter of feeding tube 10.This ball adding device 70 by spheroid 80 push feeding tube 10 interior after, contiguous these feed pumps 20 of this spheroid 80.Refer to Fig. 2, in the present embodiment, this ball adding device 70 comprises the pipe 71 of pushing the ball with feeding tube 10 internal communication, with pipe 71 goal tubes that are communicated with 73 of pushing the ball, and can manage in 71 the eyeball-pushing device 75 of start back and forth pushing the ball.These push the ball pipe 71 and feeding tube 10 vertical connections.This goal tube 73 and the shape between pipe 71 of pushing the ball form an angle, preferred, and the direction that this goal tube 73 arranges be take can make spheroid 80 rely on gravity to roll into the pipe 71 of pushing the ball as good from goal tube 73.In the present embodiment, for reducing the impact force of 80 pairs of tube walls of spheroid, this angle forming between pipe 71 and goal tube 73 of pushing the ball is less than 90 degree.During specific operation, described spheroid 80 relies on gravity to roll into and push the ball pipe 71 from goal tube 73, and eyeball-pushing device 75 promotes spheroid 80 again and rolls in feeding tube 10.
Understandable, described ball adding device 70 is not limited to above-mentioned structure, as long as guarantee to make spheroid 80 can enter in feeding tube 10.For example, an above-mentioned ball adding device 70 also available pipeline (not shown) direct and feeding tube 10 internal communication is replaced, and this spheroid 80 can rely on gravity to roll in feeding tube 10 from this pipeline; Or above-mentioned goal tube 73 is not set, and directly on the pipe 71 of pushing the ball, offer an opening (not shown), described spheroid 80 is put into the pipe 71 of pushing the ball from opening, then roll in feeding tube 10 by eyeball-pushing device 75 promotion spheroids 80.In addition, for preventing in material conveying process, material spills with the position that is communicated with of ball adding device 70 from feeding tube 10, can carry out shutoff with leakage-proof material by above-mentioned eyeball-pushing device 75 or other blocking device.
The thrust that above-mentioned feed pump 20 produces when pumping material or cleaning solution needs enough to promote this spheroid 80 in the interior movement of this feeding tube 10.
Be appreciated that as reducing the impact force of 80 pairs of pipelines of this spheroid, this spheroid 80 can be set to metal inside outer cladding rubber layer.
On the first discharge nozzle 30, be provided with on the first valve 31, the second discharge nozzles 40 and be provided with the second valve 41, with the material of controlling in feeding tube 10, from the first discharge nozzle 30 or the second discharge nozzle 40, flow out.This second discharge nozzle 40 is connected with discharge chute 43, and material can enter discharge chute 43 from the second discharge nozzle 40.The first discharge nozzle 30 is in order to discharge cleaning solution and spheroid 80.For convenient, control, in the present embodiment, the second discharge nozzle 40 is set to horizontal pipeline, this second valve 41 is installed on this horizontal pipeline, this first discharge nozzle 30 and the second discharge nozzle 40 have an angle, making spheroid 80 can rely on gravity is that spheroid 80 can rely on gravity in the interior rolling of the first discharge nozzle 30 by the first valve 31 and the first discharge nozzle 30(), so spheroid 80 relies on gravity only can enter the first valve 31, and can not enter the second valve 41.The diameter of spheroid 80 is less than or equal to the internal diameter of the first discharge nozzle 30.
Impact force to tube wall while falling for reducing spheroid 80, these the first discharge nozzle 30 ends also can connect one section of damping bend pipe 33.
On this feeding tube 10, before the first valve 31 and the second valve 41, be also provided with an inductor 90, this inductor 90 is electrically connected a controller 91; When inductor 90 has sensed that spheroid 80 is through out-of-date, this inductor 90 sends a signal to controller 91, and controller 91 receives signal and controls the opening and closing of the first valve 31 and the second valve 41.
The method of using feeder 100 of the present invention to carry out feeding, it comprises the starting stage: ball pushes away cleaning solution (discharging the interior residual cleaning solution of feeding tube 10), interstage and final stage: ball pushes away material (discharging the interior residual material of feeding tube 10).
Starting stage: ball pushes away cleaning solution, detailed process is as follows:
Step S1: rely on ball adding device 70 that described spheroid 80 is pushed in feeding tube 10.
In the present embodiment, be specially: described spheroid 80 is put into goal tube 73, and this spheroid 80 relies on gravity to roll into from goal tube 73 pipe 71 of pushing the ball, and eyeball-pushing device 75 promotes spheroid 80 and rolls in feeding tube 10.
Now, the first valve 31 is opening state, and the second valve 41 is closed condition; And before feeding, feeding tube 10, in advance through cleaning, remains cleaning solution in feeding tube 10.
Step S2: open the valve between feed pump 20 and this material-storing groove 50 and feed pump 20, so that the material in material-storing groove 50 relies on feed pump 20 to pump in described feeding tube 10.
The thrust that this feed pump 20 produces promotes material and this spheroid 80 moves to feeding tube 10 rear end.
Now, the interior formation material of feeding tube 10 body 80 of pushing the ball, spheroid 80 pushes away the interior residual cleaning solution of feeding tube 10, as shown in Figure 3.Note: because spheroid 80 is for example pushed into rear its contiguous feed pump 20(of feeding tube 10, ball adding device 70 vicinities can be arranged on to feed pump 20 rear end), therefore when feed pump 20 pumps into material when feeding tube 10 is interior, can form the material body 80 of pushing the ball, between material and spheroid 80, there is no cleaning solution or only have negligible cleaning solution.
Step S3: spheroid 80 is through inductor 90, and this inductor 90 sends a signal to controller 91, controls the first valve 31 at spheroid 80 by the rear controller 91 of the first valve 31 and closes, and the second valve 41 is opened.For guaranteeing that spheroid 80 is by rear first valve 31 of just closing of the first valve 31, this controller 91 receives after the signal of inductor 90, can the time delay some time, guarantee that spheroid 80 can pass through the first valve 31.
So, spheroid 80 and cleaning solution enter the first discharge nozzle 30 by the first valve 31 and discharge from the first discharge nozzle 30; Material enters the second discharge nozzle 40 from the second valve 41, and enters in discharge chute 43 through the second discharge nozzle 40.
Above-mentioned step S1-S3 is the starting stage: ball pushes away the process of cleaning solution, can effectively avoid cleaning solution to sneak into the concentration to material in material and exert an influence.
Interstage (step S4): as required, continue to rely on feed pump 20 to pump into material in feeding tube 10, and discharge by the second valve 41, the second discharge nozzle 40 successively.
Because carried material has high concentration, need clean in time feeding tube 10, because clean not in time, material condenses in after becoming dry on the tube wall of feeding tube 10 and will become and be difficult to removal, affects the subsequent delivery of material.
Final stage: ball pushes away material, detailed process comprises the following steps:
Step S5: make feed pump 20 stop conveying material, and rely on ball adding device 70 that described spheroid 80 is pushed in feeding tube 10.
Spheroid 80 is pushed to feeding tube 10 is interior specifically can join upper step S1.
Step S6: open the valve between feed pump 20 and this water pipe 60 and feed pump 20, so that the cleaning solution in water pipe 60 relies on feed pump 20 to pump in described feeding tube 10.
Now, the first valve 31 is closed condition, and the second valve 41 is opening state.
The thrust that this feed pump 20 produces promotes cleaning solution and this spheroid 80 moves to feeding tube 10 rear end.
Now, the interior formation cleaning solution of feeding tube 10 body 80 of pushing the ball, spheroid 80 pushes away the interior residual material of feeding tube 10, as shown in Figure 4.Note: because spheroid 80 is pushed into its contiguous feed pump 20 after feeding tube 10, therefore when feed pump 20 pumps into cleaning solution when feeding tube 10 is interior, can form the cleaning solution body 80 of pushing the ball, between cleaning solution and spheroid 80, there is no material or only have negligible material.
Because the diameter of spheroid 80 equates with the internal diameter of feeding tube 10, therefore described spheroid 80 can will remain under the material scraper of feeding tube 10 tube walls, prevents that material is in the obstruction of condensing of feeding tube 10 tube walls.Cleaning solution in feeding tube 10 can be effectively to cleaning in pipeline.
Step S7: spheroid 80 is through inductor 90, and this inductor 90 sends a signal to controller 91, all controls the second valve 41 by the rear controller 91 of the second valve 41 at residual material and closes, and the first valve 31 is opened.For guaranteeing that residual material is by rear second valve 41 of just closing of the second valve 41, this controller 91 receives after the signal of inductor 90, can the time delay some time, guarantee that residual material can be all by the second valve 41.So, residual material enters the second discharge nozzle 40 by the second valve 41, through the second discharge nozzle 40, enters in discharge chute 43; Spheroid 80 and cleaning solution enter the first discharge nozzle 30 by the first valve 31 and discharge from the first discharge nozzle 30.
Above-mentioned step S5-S7 is final stage: ball pushes away the process of material, so, not only can send in the second discharge nozzle 40 remaining under the material scraper of feeding tube 10 tube walls, has avoided the waste of material, but also can clean feeding tube 10.
In addition, those skilled in the art also can make various modifications, interpolation and the replacement in other form and details in the claims in the present invention scope of disclosure and spirit.Certainly, the variations such as various modifications, interpolation and replacement that these are made according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
