Description
The present invention relates to a kind of device that is used for conveying bulk materials.
In particular, the present invention relates to a kind of such device: this device can be used in chemistry and/or make up a prescription and/or food department and need unloading to keep in other any department of container of bulk material, and this bulk material comprises powder, bead, tablet or similar products.
Said vesse is drained on the relieving platform on the plane on being arranged on, and the material that is contained in the container is transported to the collection platform that is arranged on the lower flat from relieving platform.Collect platform and comprise the receiver that is connected in the processing equipment for example chest or funnel, in this processing equipment, bulk material is carried out subsequently treating process.
Diff-H between the above-mentioned plane is such, and it makes container to come emptying by action of gravity.
For bulk material is flow into the receiver of bottom from upper container, it is known using cylindrical tubular type parts, and these parts connect two planes.Tubular bag or flexible tube that top and bottom are connected in the loading inlet of the unloading outlet of container and receiver separately coaxially are inserted in the described tubular member.
This container comes emptying by making bulk material by flexible tube, and this flexible tube must be connected in container and the receiver in air tight mode basically, does not therefore have the bulk material powder to overflow.If especially powder comprises chemical constitution or material, so necessarily there is powder to be diffused in the environment, these chemical constitutions or material are difficult for degraded and/or have constituted potential health problem in environment.
Major issue is to have such possibility: bulk material it by above-mentioned flexible tube when upper container arrives the lower tank because its homogenieity has been lost in the separation of composition, this flexible tube is under normal circumstances very long.
When this material comprises powder, this shortcoming especially severe that becomes, in fact, when a large amount of powder when flexible tube falls fast, be easy to generate by the various compositions that constitute powder and separate or layering.
Be to have such possibility fast by another relevant shortcoming of flexible tube: owing to arrive the excessive bead or the tablet of having damaged of speed at tube end place.
In order to overcome above-mentioned shortcoming, some systems have been developed, in these systems, before the interception parts that are arranged on upper container supply port place are opened, the partially flexible pipe assigns to block by the clamping section, and this clamping part is designed to vertically slide on both direction along flexible tube.When the interception parts of supply for receptacles mouth (outfeed) were opened, a large amount of bulk materials that enter flexible tube are the bigger drop of motion between upper container and bottom receiver suddenly.But it stops at immediately by clamping section branch narrow part that produce, flexible tube.Then, clamping part begins to move downward, slide in contact with flexible tube, and open gradually be positioned at its top, flexible tube become big part gradually.Consequently, flexible tube is filled bulk material gradually, and it is opened and till these powder can begin freely to flow to the bottom receiver at last when arriving the receiver of adjacent lower when clamping part.
Second kind of system that design overcomes above-mentioned shortcoming has tubular bag, and an end of this tubular bag is connected on supply port (outfeed) opening of the container that bulk material is housed, and its other end is connected in user's the device bottom.A valve member is connected in the supply port opening, and some interception parts are arranged on the length of bag (bag) spaced reciprocally, and these interception parts are connected on the tubular bag.Each interception parts is designed in pathway closure situation and the maximum size that changes the passage of tube interior between the situation of opening.

Control and command unit 32 are connected on the electric notor 17.
For device 1, tooth flange 15 is arranged and has tooth miniature gears 19 to form to be used for the device 33 of the motion between the transmission electric notor 17 and first tubular member 11.
According to unshowned, one embodiment of the present of invention, driving device 33 comprises: wheel, and it is substituted with tooth miniature gears 19 and is installed on the S. A. 18 of motor 17; And flexible gearing, it is delivered to motion on the flange 15 from motor 17, and this flange 15 is not the flange that tooth is arranged in this case.
For device 1, the first and second rigidity tubular members 11,26 have formed the recking means for cargo 34 of flexible tube 12 with motor 17 and motion gear 33.
In fact, shown in Figure 1 and according to being in the technique known initial situation basically, flexible tube 12 is inserted in the rigid pipe 5, and its end 12a, 12b are connected on first and second tubular members 11,26 in the mode of vapor seal separately.
From the situation of Fig. 1, control and command unit 32 drive electric notor 17, and this electric notor 17 makes first tubular member 11 be rotated along first hand of rotation around axis A by miniature gears 19 and flange 15.
During the described rotation of first tubular member 11, come bonded assembly flexible tube 12 to bear twisting resistance by the first end 12a, this twisting resistance is wrapped on the itself it, thereby little by little reduces its internal capacity and cross-sectional plane.
As shown in Figure 2, with after 26 carry out relative the rotation, at least a portion 35 of flexible tube 12 has distortion basically or is wrapped in the shape of the rope on the itself, so it can prevent that any material from passing through in its inside at tubular member 11.
This part 35 under normal circumstances begins to be formed by the central area with respect to the pipe 12 of its longitudinal extension length, and end 12a and the 12b towards it extends on both sides then.
When the longitudinal extension length of this part 35 arrived predetermined plane, control and command unit 32 stopped motor 17, thereupon, the rotation of first tubular member 11 are stopped.
Advantageously, diaphragm portion 28 drives by control and command unit 32, clamps flexible tube 12 under above-mentioned encapsulation situations, in this case, can prevent that any material from passing through in its inside.
Just now described situation is shown in Figure 2 those basically.
From situation shown in Figure 2, according to certain methods known thereby that at length do not illustrate or describe, relieving platform 3 is supplied with the bulk material 2 that has from container, and this container does not illustrate in the accompanying drawings.
As shown in Figure 3, bulk material 2 begins to flow downward in flexible tube 12.
When descending along flexible tube 12 with material, and in order to allow described decline, control and command unit 32 CD-ROM drive motor 17, therefore, use driving device 33, first tubular member 11 is rotated along such hand of rotation, and this hand of rotation is with to be used for front first hand of rotation of winding pipe 12 opposite.
In other words, untiing of control flexible tube 12 filled bulk material 2 gradually thereby allow to manage 12.
In Fig. 4, flexible tube 12 illustrates under these circumstances, and in this case, diaphragm portion 28 is on the clamped position, and it is to be filled as much as possible basically.
The function of diaphragm portion 28 guarantees that basically flexible tube 12 unties from the top downwards, thereby prevents that it from untiing on both sides, prevents that promptly it from untiing from two ends.
Another function of diaphragm portion 28 is, in case pipe is filled into predetermined extent, so it can prevent flexible tube 12 and upper tubular parts 11 irrelevant to rotation untie because in pipe 12, have the thrust that is produced by a large amount of bulk materials 2.
Thereby can causing, this thing do not wish the uncertain factor that takes place in the course of conveying that usually is very accurate strict effective control.And, thisly untie automatically too suddenly and the material 2 that descends along flexible tube 12 is dropped in second funnel 24 excessively.Advantageously, in order to overcome this shortcoming, added diaphragm portion 28, and diaphragm portion 28 is arranged near second tubular member 26, therefore when this part 28 was opened, bulk material 2 landing in the flexible tube 12 were restricted.
Fig. 5 shows such situation, and in this case, flexible tube 12 is opened fully, and bulk material 2 directly flow to from the relieving platform 3 that is arranged on upper plane L1 and is arranged on the accepting in the platform 4 of lower flat L2 place.
Just now a kind of like this state of institute's description situation representative: speed is depended in the conveying of the bulk material 2 between the platform 3 and 4.
Finished flowing on the flexible tube 12 in case finished the conveying of bulk material 2 and this material 2, use known method (owing to be known method, therefore not have below to describe in detail) to make sealing arrangement 30 move in the flexible tube 12 so and be driven by sealing it and the lower area of blanked-off pipe 12.
Then, according to known method, make sealing arrangement 30 move apart flexible tube 12, these do not illustrate, and after the suitable valves parts that this paper does not have to describe were closed, pipe 12 moved apart the inside of rigid pipe 5, is not distributed in the environment and do not have any material 2.
On this position, device 1 is designed to accept to be used for supplying with the new flexible tube 12 of new bulk material 2, and this bulk material 2 can be different from the material of being considered so far, and repeats above-mentioned algorithm.
Term " recking means for cargo " 34 refers to such device, and this device design is relative to each other rotated two ends 12a, the 12b of flexible tube along two hand of rotation.
In other words, with reference to the foregoing description, if rotate and twine flexible tube 12 by making first tubular member 11 carry out anticlockwise direction with respect to the second fixing tubular member 26, being rotated in the opposite direction by first tubular member 11 so is that right-hand revolution has been untied pipe 12.
Advantageously, be connected to the variable tube-shaped joint of development length on the second rigidity tubular member 26 27 allow to change to compensate, flexible tube 12 is along the length of axis A direction, it is because the mouth of pipe is subjected to twisting caused that this length changes.Therefore, for installing 1, tube-shaped joint 27 forms the device 36 of the length variations that is used for compensating flexible tube 12.
And advantageously, because its elastic construction, during twining and during untiing and filling simultaneously, and during bulk material 2 passed through its step, tube-shaped joint 27 can remain on its tension force in the scope of predetermined value flexible tube 12.Therefore, for installing 1, spring tube Y joint 27 has formed and has been used for the device 37 of tensioning flexible tube 12.
According to another embodiment of unshowned tightening device 37, device 37 comprises some joints with variable development length, and this development length is applied to tension on the flexible tube 12 by gravity.In other words, this joint can not be applied to elastic reaction on the pipe 12.But at least a portion can be applied to along the gravity that axis A carries out some parts of free-moving this joint on the pipe 12.
Advantageously, during the step of twining and untiing and fill simultaneously, and at bulk material 2 by during its step, the existence with the variable tube-shaped joint 27 of the development length that is connected on the second rigidity tubular member 26 makes flexible tube 12 to remain on its tensile force in the predetermined range.
Advantageously, in extremely simple but same effective method, when material 2 is transported to when accepting the platform 4 from relieving platform 3 by above-mentioned flexible tube 12, device of the present invention can prevent that material 2 is by layering or be damaged.
Advantageously, the present invention also allows by this way bulk material 2 to be transported to from relieving platform 3 to accept the platform 4, so that makes this material separate with surrounding environment fully, so can prevent that in this method powder is diffused in the environment nocuously.
Described the present invention is suitable for tangible technical application, and can improve and change in the scope that does not break away from the principle of the invention.And all details of the present invention can replace with technical equivalent elements.
