Detailed Description

The research of our company finds that the reason why the discharging of the bin is not smooth is as follows:

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

The problems are that: when feeding the seal cabin 900, air at the bottom of the seal cabin 900 is pressed inside to form an air cavity 902, the air cavity 902 cuts off the flow of the seal cabin 900 to the auger inlet 903, and the discharging auger 901 cannot pump air in the air cavity 902, so that discharging cannot be performed.

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 generates attractive force to the normal material area 900 and also blocks the material from being discharged.

The company concludes that: the new bulk material storage device breaks the air cavity 902 and the upper vacuum area 904 to preserve the material for smooth discharge.

The utility model will be described in detail below with reference to the drawings and detailed description thereof.

Referring to fig. 2, a bulk material storage device comprises a support system 100, wherein the support system 100 is connected with a sealed bin 200, the sealed bin 200 is a bin for storing bulk materials, at least one feeding hole 201 is arranged at the top of the sealed bin 200, the lower part of the sealed bin 200 is communicated with a discharging system 300, the discharging system 300 is fixed on the support 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 inlets 201 are arranged at the top of the seal bin 200 along the length direction, wherein the middle feed inlet 201 is a main feed inlet, and the other two feed inlets 201 are auxiliary feed inlets. When feeding the seal cartridge 900, a main feed port is generally first used, because the material is granular, which may 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 at the moment, so that the goods can be loaded as much as possible.

As shown in fig. 2 and 17, the respiratory system 400 includes an external breathing tube 260, the external breathing tube 260 is positioned in the cabin of the sealed cabin 200, one end portion of the external breathing tube 260 is communicated with the cabin space at the top of the sealed cabin 200, and the other end portion of the external breathing tube 260 extends to the outside of the sealed cabin 200 and is communicated with the outside. The function of the outer breathing tube 260 is to place the headspace within the sealed cartridge 200 in communication with the outside world, facilitating breaking of the upper vacuum region 904 above. The "relationship of the inner end of the outer breathing tube 260 to the top of the seal cartridge 200" refers to the "relationship of the upper end of the inner breathing tube 420 to the top of the seal cartridge 200".

As shown in fig. 2, 5, 6 and 17, the respiratory system 400 further includes at least one inner breathing tube 420, wherein the inner breathing tube 420 is located inside the sealed cabin 200, the number of the inner breathing tubes is set according to the length of the sealed cabin 200, one inner breathing tube 420 is set approximately every 0.3-0.6 m, the inner breathing tube 420 is vertically set, the lower end part of the inner breathing tube 420 is communicated with the bottom space of the sealed cabin 200, and the upper end part (see reference numeral 421) is spaced from the inner wall of the cabin top of the sealed cabin 200 (see reference numeral 423). The function of the inner breathing tube 420 is to allow the headspace within the sealed enclosure 200 to be compared to the footspace within the sealed enclosure 200, facilitating breaking of the lower vacuum region 902 above. When the material is fed from the feed 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 to the inner wall of the bin top of the bin 200 as possible, as long as the upper end of the inner breathing tube 420 can be kept to be capable of entering and exiting.

As shown in fig. 5-8, the discharging system 300 comprises a horizontal auger 310, a vertical auger 320 and a discharging hose 340, wherein the horizontal auger 310 is arranged at the bottom of the sealed cabin 200, a plurality of discharging through holes 311 are arranged on the outer wall of the horizontal auger 310, the inside of the horizontal auger 310 is communicated with the bottom of the sealed cabin 200 through the discharging through holes 311, and the outlet of the horizontal auger 310 is communicated with the bottom of the vertical auger 320. The horizontal auger 310 is arranged at a low level to facilitate the automatic outflow of all the material from the sealed bin 200, but it is possible that the inlet of the equipment receiving the material is relatively high (such as a cement mixer), so that the vertical auger 320 is arranged to raise 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 includes upper and lower ends: 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 seal cabin 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 and is rotationally connected with the upper end part, the outlet (see reference numeral 332) of the upper outer wall 330 is communicated with one end part of the discharging hose 340, and the discharging hose 340 is positioned above the seal cabin 200. In this way, the upper outer wall 330, the fixed discharging hose 340 and the hanging arm 350 can rotate along the axis of the vertical auger 320, so that the discharging port of the discharging system 300 can be matched and cooperated with the equipment for receiving materials.

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 a tightening bolt 328, the tightening bolt 328 is arranged along the radial direction of the vertical auger 320, and when the tightening bolt 328 contacts the upper end of the lower outer wall 321, the upper outer wall 330 and the upper end of the lower outer wall 321 cannot rotate; when the abutment 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, tightening the bolt 328 resembles a lock, and the rotational state of the upper outer wall 330 and the lower outer wall 321 can be adjusted.

In order to keep the discharge hose 340 stable, as shown in fig. 5, a boom 350 is fixed to the upper outer wall 330, and the boom 350 is connected to the discharge hose 340 by a rope (not shown in the rope drawing), and the boom 350 is located above the discharge hose 340.

In order to avoid the outer end of the outer breathing tube 260 from being bumped, it extends from the bottom surface of the sealed cartridge 200 to the outside, as shown in fig. 17.

As shown in fig. 2 and 15, in order to facilitate discharging, the cross-sectional shape 210 of the lower part of the seal cartridge 200 is tapered with a large upper part and a small lower part, and the transverse auger 310 is positioned below the taper point of the seal cartridge 200.

In order to bring the respiratory system to a more downstream position, as shown in fig. 7-8, the lower end of the inner breathing tube 420 is secured to the outer wall of the transverse auger 310, and the interior of the inner breathing tube 420 communicates with the interior of the transverse auger 310 (see reference numeral 423). When the inside of the inner breathing tube 420 is communicated with the inside of the transverse auger 310 and then fed into the sealing cabin 200, air in the transverse auger 310 can directly reach the top of the sealing cabin 200 along the inner breathing tube 420, and the inside of the transverse auger 310 can not form the air cavity 902.

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

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

In order to facilitate auger discharge, as shown in fig. 9-13, auger spindle 315 (i.e., the axis of rotation of stationary helical blade 316) at the discharge end of either auger 310 or auger 320 is provided with a plurality of square blades 317, square blades 317 being radially square, radially, and evenly distributed along auger spindle 315, such that material reaching this region is agitated by square blades 317, relies upon centrifugal force (or inertial force, which causes the rotating object to move away from its center of rotation), and material moves at a greater rate away from auger spindle 315 and into auger 320 or discharge hose 340, as is shown only in fig. 9-13 for the area of auger 310, as is the discharge end of auger 320, and is not repeated.

The square blade 317 is provided with four or six.

When the horizontal auger 310 or the vertical auger 320 drives the material to discharge, the main shaft of the horizontal auger is also subjected to a reverse reaction force, that is, an axial force exists between the end part of the main shaft and the outer wall of the auger, and a circumferential rotation friction force exists, which is generally connected by using a thrust bearing, but two problems exist: one is: the length of the sealing bin 200 can reach 4-8 meters, the discharging speed is high (the whole bin materials can be discharged out in about 20-30 minutes), the reaction force is very large, the axial force born by the thrust bearing is also large, and the damage of the thrust bearing can be accelerated; the other is: the material may be very fine (e.g., cement) and even if a sealing member 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.

To this end, as shown in fig. 14 to 16, the end of the packing auger spindle (see reference numeral 327) at the feed end of the packing auger 310 or the packing auger 320 is keyed to the transition shaft 600, the outer wall of the end (see reference numeral 322) holds the pallet 610, the pallet 610 is provided with the rotation chamber 611 on the side facing the transition shaft 600, one end (the end far from the packing auger spindle) of the transition shaft 600 is extended into the rotation chamber 611, a rotation ball 620 is provided between the transition shaft 600 and the bottom chamber wall of the rotation chamber 611, and the transition shaft 600 is clearance-fitted with the side chamber wall of the rotation chamber 611. When the auger spindle rotates (works), the transition shaft 600 and the auger spindle synchronously rotate, the supporting plate 610 and the outer wall of the auger are kept motionless, the transition shaft and the auger spindle are transited through the rotating beads 620, the rotating beads 620 can resist the reaction force of the previous section and also can overcome the circumferential rotation friction force, and the space between the rotating beads 620 and the side cavity wall of the rotating cavity 611 is larger, so that the material entering is prevented; meanwhile, the side cavity wall of the rotating cavity 611 can also support the radial direction of the transition shaft 600, and even if the rotating beads 620 are slightly worn, the operation of the rotating shaft is affected, so that the rotating shaft is very practical.

As shown in fig. 16, in order to facilitate positioning of the rotating beads 620, the bottom of the rotating cavity 611 and the end of the transition shaft 600 are provided with concave cavities 612 that cooperate with the rotating beads 620 to prevent the rotating beads 620 from swinging left and right.

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

Referring to fig. 12, in order to adjust the height of the support system 100, the support system 100 includes a chassis 140, the chassis 140 fixes four hydraulic legs 141, and when the bulk material storage device is loaded, the hydraulic legs 141 are extended, the height of the chassis 140 becomes high, and a vehicle is conveniently driven into the lower portion of the chassis 140; the hydraulic legs 141 are shortened, the height of the chassis 140 is lowered, and the chassis 140 is pressed against the vehicle to complete loading.

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, and the four weight sensors 110 are electrically connected to a PLC (not shown in the drawings), 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 bin 200 and the materials, if the weight of the discharged material 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 fact that the material is discharged W2 is indicated, and the PLC informs the auger motor of the discharging system 300 to stop at the moment, so that the discharging amount is convenient to control.

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

As shown in fig. 17, when loading the sealed cabin 200, some companies are transported by pipelines and also need to use pipelines to be docked with the sealed cabin 200, for this purpose, an auxiliary feeding pipeline 410 is fixed on the sealed cabin 200, the inner end of the auxiliary feeding pipeline 410 extends into the cabin roof, and the upper end of the auxiliary feeding pipeline is separated from the inner wall of the cabin roof of the sealed cabin 200 (the distance is see the upper end position of the inner breathing tube 420), and the outer end (see the reference numeral 412) of the auxiliary feeding pipeline 410 can be docked with the pipelines of the companies.

As shown in fig. 17, for convenience of feeding, a part of the auxiliary feeding pipe 410 extends inward 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 between the spraying directions of the two rows of discharge holes 411 is 45 °, so that materials are sprayed to both sides at the same time during feeding, and quick feeding is realized.

The seal cartridge 200 is extremely disadvantageous to the weight sensor and may be damaged even when it reaches the influence of road bumps or the like during transportation, and the weight sensor is not used at this time.

2-4, a plurality of (typically four) weighing plates 240 are fixed on the seal bin 200, the weight sensor 110 is arranged on the support system 100, the weighing plates 240 are matched with the weight sensor 110 in number, the weighing plates 240 are positioned above the weight sensor 110, the cushion block 111 is fixed on the support system 100, nuts 241 are fixed on the weighing plates 240, the nuts 241 are internally threaded and matched with bolts 242, the bolts 242 are vertically arranged, the upper ends of the bolts 242 are nuts 242, and when the lower ends (see reference numeral 243) of the bolts 242 contact the cushion block 111, a distance (meaning that the weighing plates 240 are not contacted with the weight sensor 110) can be formed between the weighing plates 240 and the weight sensor 110; when the lower end portion (see reference numeral 243) of the bolt 242 does not contact the pad 111, the weight plate 240 contacts the weight sensor 110. Thus, by screwing the bolts 242, it is possible to adjust whether the weighing plate 240 contacts the weight sensor 110 (both are not in contact during transportation, and the weight sensor 110 is protected; both are in contact during operation, and the weight sensor 110 is normally weighed).

In the above adjustment, the vertical position of the seal cartridge 200 needs to be changed, that is, one degree of freedom needs to be preserved in the vertical direction of the seal cartridge 200, but in transportation, a constraint needs to be preserved in the horizontal direction of the seal cartridge 200, and a special connection manner is needed between the support system 100 and the fixed seal cartridge 200, as follows:

as shown in fig. 2-4, a plurality of (typically four) supporting legs 230 are fixed on the seal cabin 200, leg sleeves 120 are arranged on the support system 100, the number of the supporting legs 230 is matched with that of the leg sleeves 120, the upper parts of the leg sleeves 120 are opened, the lower end parts of the supporting legs 230 are positioned in the leg sleeves 120, circular through holes 121 are respectively arranged on two opposite side walls of the leg sleeves 120, strip-shaped holes 231 in the vertical direction are arranged on the supporting legs 230, and pins (not shown in the drawing) sequentially penetrate through one circular through hole 121, the strip-shaped holes 231 and the other circular through hole 121.

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

During transportation, the leg cover 120 provides a constraint to the leg 230 in the horizontal direction, and the pin can prevent the leg 230 from going out of the leg cover 120 in the vertical direction, so that the transportation is safer. However, by sliding the pins within the bar-shaped holes 231, the seal cartridge 200 has a small length of up-and-down movement space relative to the support system 100, which is sufficient to leave adjustment space for the adjustment of whether the load plate 240 contacts the weight sensor 110.

The bulk material storage device of the present utility model has been advanced but has been deficient: when one bulk material storage device is completely unloaded from a material using component (such as a cement mixing plant), the bulk material storage device in operation needs to be removed, and then a new bulk material storage device filled with a bin is continuously unloaded from the material using component (such as the cement mixing plant), so that the replacement of the two bulk material storage devices requires about half an hour, and continuous feeding of the material using component is not possible.

To this end, as in fig. 20, a bulk material storage device is constructed as a bulk material storage device, differing only in the downstream discharge means by which the outlet (see reference numeral 332) of the upper outer wall 330 of the vertical auger 320 communicates: the outlet of the upper outer wall 330 of the bulk material storage device (see reference numeral 332) communicates with the inlet of the feed auger 700 and the outlet of the feed auger 700 (see reference numeral 701) is connected with a feed conduit (not shown).

As shown in fig. 20, the feed line is a hose for convenience and for docking with the bulk material storage device in operation.

20-21, a method of feeding a bulk material storage device includes first transporting a bulk material storage device 800 to an active bulk material storage device (see reference numeral 801) using a conveyance 802, rotating (either manually or mechanically) an upper outer wall 330 of a vertical auger 320, directing the bulk material storage device 700 to the active bulk material storage device, extending a feeding conduit into a feed port 201 of the active bulk material storage device, driving a discharge system of the bulk material storage device 800, and transferring material of the bulk material storage device 800 to the active bulk material storage device. This process is approximately 20 minutes more.

The vehicle 802 is a motor vehicle.

In this way, when the rest materials of the bulk material storage device in operation are not much, the materials of the material supplementing bulk material storage device 800 can be transferred to the bulk material storage device in operation, and in the transfer process, the bulk material storage device in operation can still continue to discharge, so that the work of material using components (such as a cement stirring station) is not influenced, and the continuous feeding of the cement stirring station by the bulk material storage device in operation is realized, so that the bulk material storage device in operation is very convenient.

The working principle is as follows:

cement will be described below as an example.

As shown in fig. 19, the bulk material storage device is placed on a motor vehicle, moved to a cement manufacturing plant, bulk cement from the cement manufacturing plant is conveyed into the bulk material storage device through a feed inlet 201 or an auxiliary feed pipeline 410, then the bulk material storage device is conveyed to a cement using place through the motor vehicle, a discharge hose 340 is aligned with an inlet of a cement stirring station, and the bulk material storage device is used for accurately feeding the cement stirring station through the cooperation of a weight sensor and a PLC energy component.

When the excess material of the bulk material storage device is not much, the bulk material storage device is continuously fed to the cement mixing plant by the other bulk tank trucks to the vicinity of the working bulk material storage device (see reference numeral 801) which is driven to the construction site through the 410 pipeline for pneumatic beating or the material of the bulk material storage device 800 is transferred to the working bulk material storage device for feeding, so that the bulk material storage device is very convenient.

See the prior art for further content.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
