As shown in fig. 1 to 4, the invention provides a device for preventing fluffy material starch from being added, which comprises a starch bin 1 for storing starch, a dragon conveyor bin 2 arranged below the starch bin 1 and used for conveying starch, and a cylindrical tank 4 arranged at a discharge port of the dragon conveyor bin 2, wherein a weightlessness scale 5 is arranged on the cylindrical tank 4, a blanking component 7 is arranged between a discharge port 3 of the starch bin 1 and a feed port 6 of the dragon conveyor bin 2 and used for scraping the inner wall of the starch bin 1, a vibration component 8 is arranged on the cylindrical tank 4 and used for shaking off the fluffy material on the tank wall of the cylindrical tank 4, the blanking component 7 comprises a sweeping air bag 9, the sweeping air bag 9 is contacted with the inner wall of the starch bin 1 after being expanded, and sweeps the inner wall of the starch bin 1 in the circumferential direction to scrape the fluffy material.
The vibration assembly 8 comprises a vibration source 10 and a plurality of dispersing vibration heads 11, wherein the plurality of dispersing vibration heads 11 are installed on the outer wall of the cylindrical tank 4, and the vibration source 10 drives the plurality of dispersing vibration heads 11 to beat the cylindrical tank 4 from different directions so as to break off materials adhered to the inner wall of the cylindrical tank 4.
In practical application, the device mainly carries out blanking on the whole device through the blanking assembly and the vibration assembly. Wherein, the vibrations subassembly is continuous work, and it is continuous for the cylinder jar to vibrate. And the blanking component scrapes materials by leading the sweeping air bag to extend into the starch tank when the starch in the starch bin is discharged to an empty bin.
For the present device, the blanking for starch is a method by single blanking ration. This is the blanking method commonly used in the prior art, and the parts involved are all the prior art, so they are not described in detail. The working principle of which is only briefly described below.
In the device, a pneumatic valve and a controller are arranged on a starch bin, the amount of material to be fed for a single time is set in the controller in advance, and then the pneumatic valve is opened for feeding when in use (the feeding amount is controlled by the opening time of the pneumatic valve, and the pneumatic valve is automatically closed after the specified opening time is reached).
Then the materials enter the auger delivery bin and are delivered to the weightless scale in the cylindrical tank by the auger delivery bin. The weightlessness scale is arranged in the cylinder tank and divides the cylinder tank into an upper layer and a lower layer, the weightlessness scale is also provided with a pneumatic switch, when the weight of the material on the weightlessness scale reaches a preset value, the weightlessness scale opens the pneumatic switch to enable the material on the upper layer to be transferred to the lower layer, and finally the switch at the bottommost part of the cylinder tank is opened by the lower layer to enable the material to enter the mixing tank for gypsum board production. The steps are the steps of finishing single blanking of the starch.
In the working process, the two positions are easy to generate the filling materials, so that the blanking accuracy is influenced. Namely on the bin wall of the starch bin and the tank wall of the cylindrical tank. The vibration component is arranged in the device to continuously vibrate the cylindrical tank so as to eliminate the filling material on the cylindrical tank.
During the use process of the bin wall of the starch bin, the starch bin often has a material blocking state when the starch bin is empty (powder at the edge part is bonded on the bin wall due to the fact that the starch is affected with moisture or the original powder in the starch bin is extruded). At present, the filling material adhered to the wall of the silo at the last point is removed by vibration during the last blanking or is not removed in a short time, and the filling material is directly supplemented. But if not get rid of and can make the accuracy of last unloading unable assurance (total material volume fills in according to single unloading volume in the feed bin, total material volume just can satisfy the unloading of fixed frequency, if the storehouse wall fluffy material takes place, can make the accuracy of last unloading go wrong). Therefore, the existing production method which adopts a method without removal usually does not carry out weighing calculation on the last blanking.
Under this background, this device has set up the unloading subassembly, scrapes the material to the bulkhead, makes the starch storehouse unloading last time also keep accurate.
In addition, this device can further guarantee the ration of starch to add through optimizing the unloading method in addition to having set up unloading subassembly and vibrations subassembly and guaranteeing the unloading accuracy:
1. after the starch bin is fed to the weightlessness scale, a preset feeding value can be set on the weightlessness scale. When the actual weight weighed by the weightlessness scale is larger than the set preset value, the weightlessness scale sends an instruction to drive a switch on the weightlessness scale to open, blanking is carried out until the actual weight weighed by the weightlessness scale reaches the weight obtained by subtracting the preset value from the previous weight, and the weightlessness scale sends an instruction to drive the switch to close at the moment, and blanking is stopped;
2. when the actual weight weighed by the weightlessness scale is smaller than the set preset value, the weightlessness scale does not send an instruction to open the switch on the weightlessness scale, but sends an instruction to open the pneumatic valve positioned in the starch bin to enable the starch bin to continue feeding until the actual weight weighed by the weightlessness scale is not smaller than the set preset value, and at the moment, the weightlessness scale sends an instruction to close the pneumatic valve on the starch bin to enable the switch to be opened to carry out feeding.
For example, the blanking amount of 2KG is set on a controller and a weightlessness scale of a starch bin in advance, the amount of 2KG below a pneumatic valve of the starch bin is opened, the amount after the weightlessness scale is reached is 2.1KG due to the vibration of the device or the storage in a hinged conveyor conveying bin, then the switch is immediately opened for blanking after the weightlessness scale weighs 2.1KG, the actual numerical value weighed on the weightlessness scale is gradually reduced at the moment, when the numerical value reaches 2.1KG-2kg =0.1kg, the switch is closed to stop blanking, the blanking amount is accurate, and then the 2KG amount is enabled to reach a mixing tank for producing gypsum boards by matching with a vibration assembly;
if the weighed amount of the weightlessness scale is 1.9KG, the weightlessness scale does not send an instruction to open the switch, but sends an instruction to open a pneumatic valve on the starch bin to enable the starch bin to continue to feed until the weightlessness scale receives the materials and reaches 2KG, and then sends an instruction to close the pneumatic valve of the starch bin and open the switch of the weightlessness scale to feed.
In conclusion, the device can eliminate the material blocking phenomenon through the blanking assembly and the vibration assembly to increase the blanking accuracy, and can also ensure the blanking amount by adding the optimized blanking method.
Meanwhile, the inner walls of the starch bin 1 and the discharge port 3 of the starch bin 1 are smooth mirror surfaces, so that smooth material discharging is facilitated, and materials are not adhered.
The blanking assembly 6 in the device also comprises a control box body 12 arranged between the discharge port 3 and the feed port 6 and an expansion rod 13 rotationally connected to the control box body 12, the sweeping air bag 9 is arranged on the expansion rod 13, and the edge of the sweeping air bag 9 is attached to the inner wall of the starch bin 1 after being expanded.
The control box body 12 drives the telescopic rod 13 to extend towards the inside of the starch bin 1 and drive the sweeping air bag 9 to enter the starch bin 1, and the control box body 12 also inflates towards the inside of the sweeping air bag 9 and drives the telescopic rod 13 to rotate along the axial direction so as to drive the sweeping air bag 9 to rotate along the circumferential direction of the inner wall of the starch bin 1.
The blanking component mainly scrapes the inner wall of the starch bin after the sweeping air bag is inserted into the starch bin so as to withdraw the filling material adhered to the wall of the bin. In the device, a control box body and a telescopic rod are arranged, a sweeping air bag is arranged on the telescopic rod, and the movement of the telescopic rod and the sweeping air bag is controlled by the control box body.
In the device, the sweeping air bag needs to perform the following actions to scrape the inner wall of the starch bin: the sweeping air bag is inserted into the starch bin, the sweeping air bag is inflated to enable the sweeping air bag to be attached to the bin wall, and the telescopic rod is rotated to drive the sweeping air bag to rotate. All three actions are driven by the control box body.
The first action is to stretch the sweep air bag into the starch bin, and the telescopic rod is driven by the control box body to stretch. The control box body is arranged between the discharge port and the feed port, so that the control box body is smaller in appearance and smooth, and cannot block falling of materials and enable the materials to be stored on the control box body. It may be provided as a sphere or a cone. The control box body can be installed through a support frame, and the support frame is connected to the outer wall of the starch bin or the outer wall of the auger conveying bin or an external member. Only the control box body needs to be fixed.
The second action is to inflate the sweeping air bag to make it adhere to the wall of the bin, and the control box body is used to inflate the sweeping air bag through the inflation pipeline.
An inflation pipeline 14 is arranged at the side edge part of the telescopic rod 13, one end of the inflation pipeline 14 is communicated with the sweeping air bag 9, the other end of the inflation pipeline 14 is connected with the control box body 12, and the pipe body of the inflation pipeline 14 is coiled and stored through a reel.
The outside of telescopic link 13 still is provided with protection tube 16, and protection tube 16 sets up in the top of control box 12, including telescopic link 13, gas-filled pipeline 14 and the winder parcel that will retract, telescopic link 13 stretches out from protection tube 16 and stretches into in the starch storehouse 1.
The sweep gasbag sets up the tip at the telescopic link when flat (the telescopic link can be the multinode formula setting, the telescopic link of multinode formula cup joints each other, a section body of topmost can not accomodate in the pole body of below), inflation conduit binds with a section above the telescopic link and is connected, because the telescopic link has flexible attribute, so inflation conduit's pipe shaft can be curled by the winder and accomodate, inflation conduit just can stretch out or retract along with the extension or the shortening of telescopic link like this, can not cause winding phenomenon.
Because this device sets up between discharge gate and feed inlet, so set up the protection tube in the telescopic link outside can avoid starch to get into inner structure. Protection tube 16 fixed mounting is at the top of control box, and telescopic link and gas pipeline and winder setting are inside it, and its top sets up the opening, and the opening part sets up valve formula soft rubber, when the telescopic link stretches out, can break through the valve and stretch out to the valve can also seal the clearance between telescopic link and the protection tube this moment, prevents that the dust from getting into.
In addition, after the sweep airbag is used, the sweep airbag needs to be stored to prevent the sweep airbag from interfering with falling materials, so that a turning ring 22 is arranged on the telescopic rod 13 of the sweep airbag, the turning ring 22 is rotatably sleeved on the telescopic rod 13, the turning ring 22 is electrically connected with the control box body 12, and the control box body 12 can drive the turning ring 22 to rotate on the telescopic rod 13 by taking the axis of the telescopic rod 13 as a rotating shaft;
the outer wall of the revolving ring 22 is provided with a connecting wire 23, the other end of the connecting wire 23 is connected with the side edge of the sweep air bag 9, and the revolving ring 22 is also provided with an annular wire groove.

And the third movable actuating telescopic rod drives the sweeping air bag to rotate, which can be independently completed by the control box body. When the control box is specifically arranged, the telescopic rod is rotatably arranged in the control box, and the control box drives the telescopic rod to rotate.
In addition, because there is the difference in height between starch storehouse and the discharge gate, so when sweeping the gasbag and scraping the material, the fluffy material of eminence falls and can appear the dust because of the difference in height, can kick-back even overflow outside the feed gate. Therefore, the baffle is arranged at the discharge port, and when the sweeping air bag is inserted into the starch bin, the baffle shields and seals the discharge port, so that the problem is solved.
The chamber wall of discharge gate 3 inwards inclines to set up, and it is connected with baffle 17 to rotate through the hinge at the tip of discharge gate 3, and the incline direction of baffle 17 is the same with the incline direction in discharge gate 3 chamber wall, and baffle 17 can be in order to seal discharge gate 3 to the upset of discharge gate 3 center under the promotion of external force.
A jacking disc 18 is arranged below the baffle 17, the edge of the jacking disc 18 exceeds the edge of the end part of the baffle 17, and a material penetrating port is formed in the position, right below the discharge port 3, of the jacking disc 18 and used for passing materials.
The telescopic rod can be multi-section, so the jacking disc can be arranged on the penultimate section and can ascend when the sweeping air bag is about to stop the end point, and the baffle is lifted after the sweeping air bag finally reaches so as to complete overturning shielding. The section of telescopic link that moves the disc place promptly can lengthen under the control of control box and shorten to be located the protection tube outside under the state of complete withdrawal, move the telescopic link that the disc place promptly and can not retract into completely, but expose one section and be located the protection tube outside.
