Detailed Description

The research of our company discovers that the reason why the bin is not smooth in discharging is that:

referring to fig. 1, a general storage bin is a sealed bin 900, a discharging auger 901 is arranged at the bottom of the storage bin, when bulk materials (hereinafter referred to as materials) are discharged, the materials enter the discharging auger 901 from an auger inlet 903, and then the materials are discharged under the driving of the auger.

The problems are that: when feeding to sealed bin 900, the air of sealed bin 900 bottom can be died in the inside, and then form air cavity 902, and air cavity 902 has cut off sealed bin 900 and has flowed to auger import 903, and moreover, ejection of compact auger 901 also can not take out the air in air cavity 902, leads to unable ejection of compact.

In addition, when the material is discharged, as the normal material area 900 continuously falls, an upper vacuum area 904 is formed above the normal material area 900, and the upper vacuum area 904 may attract the normal material area 900 and may also obstruct the material discharge.

I company concluded: the new bulk material storage device can store materials and smoothly discharge the materials only by breaking the air cavity 902 and the upper vacuum area 904.

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.

Referring to fig. 2, the bulk material storage device comprises a supporting system 100, wherein the supporting system 100 is connected with a sealed bin 200, the sealed bin 200 is a bin for storing bulk materials, the top of the sealed bin 200 is provided with at least one feeding hole 201, the lower part of the sealed bin 200 is communicated with a discharging system 300, the discharging system 300 is fixed on the supporting system 100 or the sealed bin 200, and a breathing system 400 is fixed on the sealed bin 200.

As shown in fig. 2 and 9, at least three feed ports 201 are arranged at the top of the sealed bin 200 along the length direction thereof, wherein the feed port 201 in the middle is a main feed port, and the other two feed ports 201 are auxiliary feed ports. When feeding to the sealed bin 900, generally the main feed inlet is used first, because the material is granular, it will cause: when the main feed inlet is full and the two ends of the top of the sealed bin 200 have residual spaces, the auxiliary feed inlet is used, so that more goods can be loaded as much as possible.

As shown in fig. 2 and 17, the breathing system 400 includes an external breathing tube 260, the external breathing tube 260 is located in the sealed cabin 200, one end of the external breathing tube 260 communicates with the cabin space at the top of the sealed cabin 200, and the other end of the external breathing tube 260 extends to the outside of the sealed cabin 200 and communicates with the outside. The outer breathing tube 260 functions to communicate the headspace within the sealed cartridge 200 with the outside, facilitating the breaking of the upper vacuum zone 904 above. "the relationship of the inner end of the outer breathing tube 260 to the top of the sealed cartridge 200" refers to "the relationship of the upper end of the inner breathing tube 420 to the top of the sealed cartridge 200".

As shown in fig. 2, 5, 6 and 17, the breathing system 400 further comprises at least one inner breathing tube 420, the number of the inner breathing tubes 420 is determined by the length of the sealed cabin 200, one inner breathing tube 420 is arranged approximately every 0.3-0.6 meter, the inner breathing tubes 420 are vertically arranged, the lower end of the inner breathing tube 420 is communicated with the bottom space of the sealed cabin 200, and the upper end (see reference numeral 421) of the inner breathing tube is spaced from the top inner wall of the sealed cabin 200 (see reference numeral 423). The inner breathing tube 420 functions to facilitate breaking the upper vacuum region 902 above, by allowing the headspace within the sealed cartridge 200 to be in communication with the headspace within the sealed cartridge 200. When the material is fed from the feeding port 201, the material may enter the inner breathing tube 420 from the upper end of the inner breathing tube 420 to block the inner breathing tube 420, so the upper end of the inner breathing tube 420 should be as close as possible to the top inner wall of the sealed cabin 200 as long as the upper end of the inner breathing tube 420 can enter and exit the gas.

Referring to fig. 5-8, the discharging system 300 comprises a transverse auger 310, a vertical auger 320 and a discharging hose 340, wherein the transverse auger 310 is arranged at the bottom of the sealed bin 200, a plurality of discharging through holes 311 are arranged on the outer wall of the transverse auger 310, the discharging through holes 311 enable the interior of the transverse auger 310 to be communicated with the bottom of the sealed bin 200, and the outlet of the transverse auger 310 is communicated with the bottom of the vertical auger 320. The transverse auger 310 is arranged at a low position to facilitate the automatic outflow of all materials in the sealed bin 200, but the inlet of a device which can receive the materials is higher (such as a cement mixer), so the vertical auger 320 is arranged to increase the height of the discharge port of the discharge system 300.

As shown in FIG. 5, the outer wall of the vertical packing auger 320 comprises an upper end and a lower end: the upper outer wall 330 and the lower outer wall 321, the lower outer wall 321 is fixed on the support system 100 or the sealed bin 200, the lower end part of the upper outer wall 330 is sleeved or inserted in the upper end part of the lower outer wall 321, the upper outer wall and the lower outer wall are rotatably connected, the outlet (see the reference numeral 332) of the upper outer wall 330 is communicated with one end part of the discharge hose 340, and the discharge hose 340 is positioned above the sealed bin 200. Therefore, the upper outer wall 330, the discharge hose 340 fixed on the upper outer wall and the suspension arm 350 can rotate along the axis of the vertical auger 320, so that the discharge port of the discharge system 300 can be matched and cooperated with equipment for receiving materials conveniently.

As shown in fig. 5, the lower end of the upper outer wall 330 is sleeved in the upper end of the lower outer wall 321, the lower end of the upper outer wall 330 is in threaded fit with the abutting bolt 328, the abutting bolt 328 is arranged along the radial direction of the vertical auger 320, and when the abutting bolt 328 contacts the upper end of the lower outer wall 321, the upper end of the upper outer wall 330 and the upper end of the lower outer wall 321 cannot rotate; when the fastening bolt 328 does not contact the upper end portion of the lower outer wall 321, the upper outer wall 330 and the upper end portion of the lower outer wall 321 can rotate. Thus, the tightening bolt 328 is like a lock, and can adjust the rotation of the upper outer wall 330 and the lower outer wall 321.

As shown in FIG. 5, in order to keep the discharging hose 340 stable, a boom 350 is fixed on the upper outer wall 330, the boom 350 is connected with the discharging hose 340 through a rope (not shown in the rope drawing), and the boom 350 is positioned above the discharging hose 340.

As shown in fig. 17, in order to prevent the outer end of the external breathing tube 260 from being damaged, it extends from the bottom of the sealed chamber 200 to the outside.

Referring to fig. 2 and 15, for discharging, the cross-sectional shape 210 of the lower part of the sealed bin 200 is a cone with a large upper part and a small lower part, and the transverse packing auger 310 is positioned below the cone tip of the sealed bin 200.

Referring to fig. 7 to 8, in order to allow the respiratory system to reach a more downstream position, the lower end of the inner breathing tube 420 is fixed to the outer wall of the transverse packing auger 310, and the inside of the inner breathing tube 420 communicates with the inside of the transverse packing auger 310 (see reference numeral 423). When the interior of the inner breathing tube 420 is communicated with the interior of the transverse packing auger 310 and the material is fed into the sealed bin 200, the air in the transverse packing auger 310 can reach the top of the sealed bin 200 along the inner breathing tube 420, and the air cavity 902 above cannot be formed in the interior of the transverse packing auger 310.

As shown in fig. 7-8, the breathing system 400 includes a plurality of parallel internal breathing tubes 420, and the internal breathing tubes 420 are staggered with respect to the tapping holes 311 for uniform air intake. Thus, each internal breathing tube 420 corresponds to one discharge through hole 311, and external air enters more uniformly.

As shown in fig. 7-8, the tapping hole 311 is a square hole.

As shown in fig. 9-13, in order to facilitate the discharging of the auger, a plurality of square blades 317 are fixed on the auger main shaft 315 (i.e. the rotating shaft of the fixed helical blade 316) at the discharging end of the horizontal auger 310 or the vertical auger 320, and the square blades 317 are distributed uniformly and radially along the auger main shaft 315, so that the material reaching the area is stirred by the square blades 317 and depends on the centrifugal force (or the inertial force, which makes the rotating object far away from the rotating center thereof), and the material is far away from the auger main shaft 315 at a higher speed and enters the vertical auger 320 or the discharging hose 340, as shown in fig. 9-13, only the horizontal auger 310 area is shown, and as the discharging end of the vertical auger 320 is also the same, and is not repeatedly shown.

The square vanes 317 are provided with four or six.

When horizontal auger 310 or perpendicular auger 320 drive material ejection of compact, its main shaft also can receive reverse reaction force, and that is to say, there is axial force between the tip of main shaft and the auger outer wall, also has the rotary friction of circumference, generally can use thrust bearing to connect, but has two problems: one is that: the length of the sealed bin 200 can reach 4-8 meters, the discharging speed is high (the whole bin can be discharged completely within 20-30 minutes), the reaction force is very large, and the axial force borne by the thrust bearing is also large, so that the damage of the thrust bearing can be accelerated; the other one is that: the material may be very fine (e.g., cement), and even if a seal is provided at the upstream end of the thrust bearing, the material may enter the thrust bearing, which may accelerate damage to the thrust bearing.

For this purpose, as shown in fig. 14-16, the end part of the auger main shaft (refer to reference numeral 327) at the feeding end of the horizontal auger 310 or the vertical auger 320 is connected with the transition shaft 600 in a key way, the outer wall (refer to reference numeral 322) at the end part is fixed with the supporting plate 610, the supporting plate 610 is provided with a rotating cavity 611 at the side surface facing the transition shaft 600, one end (the end far away from the auger main shaft) of the transition shaft 600 extends into the rotating cavity 611, a rotating ball 620 is arranged between the transition shaft 600 and the bottom cavity wall of the rotating cavity 611, and the transition shaft 600 is in clearance fit with the side cavity wall of the rotating cavity 611. When the auger main shaft rotates (works), the transition shaft 600 and the auger main shaft synchronously rotate, the supporting plate 610 and the outer wall of the auger are kept still, the two are transited through the rotating bead 620, the rotating bead 620 can resist the reaction force of the previous section and can also overcome the circumferential rotating friction force, and the space between the rotating bead 620 and the side wall of the rotating cavity 611 is larger, so that the materials are not afraid to enter; meanwhile, the side wall of the rotating cavity 611 can also support the transition shaft 600 in the radial direction, and even if the rotating ball 620 is slightly worn, the work of the rotating ball is also influenced, so that the rotating ball is very practical.

As shown in fig. 16, in order to position the rotating ball 620, the cavity bottom of the rotating cavity 611 and the end of the transition shaft 600 are both provided with a concave cavity 612 that is engaged with the rotating ball 620, so as to prevent the rotating ball 620 from swinging left and right.

As shown in FIG. 16, for firm fixation, the outer wall of the transverse auger 310 or the vertical auger 320 fixes the supporting plate 610 through the flange plate 615.

Referring to fig. 12, in order to adjust the height of the support system 100, the support system 100 includes a base frame 140, the base frame 140 fixes four hydraulic legs 141, and when the present bulk material storage device is loaded, the hydraulic legs 141 are extended and the height of the base frame 140 becomes high, facilitating the vehicle to enter the lower portion of the base frame 140; the hydraulic leg 141 is shortened, the height of the chassis 140 becomes low, and the chassis 140 is pressed on the vehicle, so that loading is completed.

As shown in fig. 2 and 12, in order to control the discharging amount conveniently, four weight sensors 110 are disposed between the bottom frame 140 and the sealing bin 200, the bottom frame 140 is rectangular, the four weight sensors 110 are all distributed at four corners of the bottom frame 140, the four weight sensors 110 are electrically connected to a PLC (not shown in the figure), and the PLC is electrically connected to an auger motor (see reference numeral 331 of fig. 5) of the discharging system 300.

Before discharging, the four weight sensors 110 measure the total weight W1 of the sealed cabin 200 and the materials, if the weight of the discharged materials is W2, after the discharging is started, real-time data measured by the four weight sensors 110 are timely transmitted to the PLC, when the real-time data measured by the four weight sensors 110 are equal to (W1-W2), the discharging W2 is shown, and the PLC informs the auger motor of the discharging system 300 to stop at the moment, so that the discharging amount is conveniently controlled.

The PLC is electrically connected with the man-machine interaction equipment, so that the operation is convenient.

Referring to fig. 17, when filling the capsule 200, some companies are transported by pipes and also require the present invention to use pipes to be butted thereto, for this purpose, an auxiliary feeding pipe 410 is fixed to the capsule 200, the inner end of the auxiliary feeding pipe 410 extends into the top of the capsule and the upper end thereof is spaced from the inner wall of the top of the capsule 200 (this distance is referred to as the upper end position of the inner breathing pipe 420), and the outer end of the auxiliary feeding pipe 410 (see reference numeral 412) can be butted against the pipes of these companies.

As shown in fig. 17, for feeding convenience, a part of the auxiliary feeding pipe 410 extends inwards along the top wall of the sealed cabin 200, and the part of the auxiliary feeding pipe 410 is provided with two rows of discharge holes 411 (only one row is shown in the figure), and the included angle of the spraying directions of the two rows of discharge holes 411 is 45 degrees, so that the materials are sprayed to two sides simultaneously during feeding, and rapid feeding is realized.

The capsule 200 reaches the influence of road bumpiness and the like during transportation, the capsule 200 in an overweight state is very bad for the weight sensor and can even damage the weight sensor, and the weight sensor is not used at the moment.

For this purpose, as shown in fig. 2-4, a plurality of (generally four) weighing plates 240 are fixed on the sealed cabin 200, the support system 100 is provided with the weight sensors 110, the weighing plates 240 are matched with the weight sensors 110 in number, the weighing plates 240 are located above the weight sensors 110, the support system 100 is fixed with the cushion block 111, the weighing plates 240 are fixed with nuts 241, the nuts 241 are in threaded fit with the bolts 242, the bolts 242 are vertically arranged, the upper end portions of the bolts 242 are nuts 242, and when the lower end portions (see reference numeral 243) of the bolts 242 contact the cushion block 111, the weighing plates 240 can be spaced from the weight sensors 110 (that is, the two are not in contact); when the lower end portion (see reference numeral 243) of the bolt 242 does not contact the pad block 111, the weighing plate 240 contacts the weight sensor 110. Thus, by turning the bolts 242, it is possible to adjust whether the weighing plate 240 contacts the weight sensor 110 (during transportation, the weight sensor 110 is protected by not contacting the weighing plate 240; during operation, the weight sensor 110 is weighing normally by contacting the weighing plate).

In the above adjustment, the vertical position of the capsule 200 needs to be changed, that is, a degree of freedom needs to be preserved in the vertical direction of the capsule 200, but the horizontal direction of the capsule 200 needs to be preserved and restrained during transportation, and a special connection mode is needed between the supporting system 100 and the fixed capsule 200, as follows:

as shown in fig. 2-4, a plurality of (generally four) legs 230 are fixed on the sealed cabin 200, the support system 100 is provided with leg sleeves 120, the number of the legs 230 is matched with that of the leg sleeves 120, the upper portion of the leg sleeves 120 is open, the lower end portions of the legs 230 are located in the leg sleeves 120, two opposite side walls of the leg sleeves 120 are provided with circular through holes 121, the legs 230 are provided with strip-shaped holes 231 in the vertical direction, and a pin (not shown in the figures) sequentially passes through one circular through hole 121, one strip-shaped hole 231, and the other circular through hole 121.

The legs 230 are six or four pairs with the leg sleeves 120.

In transportation, the leg sleeve 120 provides horizontal constraint for the leg 230, and the pin can prevent the leg 230 from going out of the leg sleeve 120 in the vertical direction, so that the transportation is safer. However, the sliding of the pin in the slotted hole 231 allows the capsule 200 to have a small up-and-down movement space relative to the support system 100, which is enough to allow adjustment space for the adjustment of whether the weigh plate 240 contacts the weight sensor 110.

The bulk material storage device of the present invention is more advanced, but still has some disadvantages: when one bulk material storage device has finished discharging the material-consuming parts (e.g. cement mixing plant), the operating bulk material storage device needs to be removed and a new full bulk material storage device is discharged further from the material-consuming parts (e.g. cement mixing plant), so that the replacement of two bulk material storage devices takes approximately half an hour and continuous feeding of the material-consuming parts is not possible.

To this end, as shown in FIG. 20, a supplementary bulk material storage apparatus is constructed in the same manner as the bulk material storage apparatus except that the downstream discharging member communicating with the outlet (see reference numeral 332) of the upper outer wall 330 of the vertical auger 320 is different: the outlet (see the reference numeral 332) of the upper outer wall 330 of the feeding bulk material storage device is communicated with the inlet of the feeding auger 700, and the outlet (see the reference numeral 701) of the feeding auger 700 is connected with a feeding pipeline (not shown in the figure).

As shown in fig. 20, the feed line is a flexible tube for convenience of interfacing with the bulk storage unit in operation.

Referring to fig. 20-21, a feeding method of a feeding bulk material storage device, firstly, a feeding bulk material storage device 800 is transported to a working bulk material storage device (see reference number 801) by a transport means 802, the upper outer wall 330 of the vertical screw 320 is rotated (manually or by machine), the feeding screw 700 is directed to the working bulk material storage device, a feeding pipe is extended into the feeding port 201 of the working bulk material storage device, a discharging system of the feeding bulk material storage device 800 is driven, and the material in the feeding bulk material storage device 800 is transferred to the working bulk material storage device. This process is approximately 20 more minutes.

The vehicle 802 is a motor vehicle.

Therefore, when the surplus materials of the working bulk material storage device are not large, the materials in the replenishing bulk material storage device 800 can be transferred to the working bulk material storage device, and in the transfer process, the working bulk material storage device can still continue to discharge materials, so that the work of material using components (such as a cement mixing plant) is not influenced, the continuous feeding of the working bulk material storage device to the cement mixing plant is realized, and the operation is very convenient.

The working principle is as follows:

the following description will be given by taking cement as an example.

Referring to fig. 19, a bulk material storage device is placed on a motor vehicle, moved to a cement manufacturing plant, bulk cement of the cement manufacturing plant is conveyed into the bulk material storage device through a feed inlet 201 or an auxiliary feed pipe 410, the bulk material storage device is conveyed to a cement use place through the motor vehicle, a discharge hose 340 is aligned with an inlet of a cement mixing plant, and the bulk material storage device accurately feeds the cement mixing plant through the cooperation of a weight sensor and a PLC functional component.

When the bulk material storage device has a small surplus, the materials which are blown by other bulk material tankers to the vicinity of the working bulk material storage device (see reference numeral 801) on the construction site through the 410 pipeline air blasting or material supplementing bulk material storage device 800 are transferred to the working bulk material storage device for material supplementing, so that the bulk material storage device can continuously supply materials to the cement mixing plant, which is very convenient.

See the prior art for further details.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be considered as the protection scope of the present invention.
