Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of granular material transport equipment, and particularly relates to a transport bag facilitating loading and unloading of materials, a loading method and an unloading method. BACKGROUND

[0002] Most granular and powder materials are transported by vehicles. In order to reduce costs, the carriages of material transport vehicles are tank-shaped and relatively long. When loading materials, a problem is caused, i.e., materials continuously accumulate below the loading port. For materials with poor fluidity, such as cement and grain, after loading a certain amount of materials, the vehicle needs to drive on the uneven road to make a turn so as to make the materials self-level in the vibrating environment, and then continue to load materials. The efficiency is very low. In order to solve this problem, a fluidized bed is arranged at the bottom of the tank, and the materials are in a boiling state during loading, which is a good solution to automatically level during loading. The existing fluidized bed in the tank generally has several metal boxes arranged at the bottom of the tank body, a gas-permeable material is fixed on the top of the metal box, and air inlet pipes are arranged on both sides of the metal box. During loading and unloading, the fluidized bed blows air upward to balance the materials. During unloading, the fluidity of the materials is also increased, so that the materials far from the unloading port are automatically leveled and flow to the unloading port, which is very good. However, even if the materials flow and level during unloading, the layer of materials at the bottom of the carriage is difficult to be directly extracted, and manual cleaning is often required in the bottom of the tank, which is very time-consuming and laborious. In view of this, the fluidized bed in the tank is often designed to be inclined, which reduces the loading and increases the center of gravity, which is not conducive to driving safety. In addition, during turning of the vehicle, due to the fluidity of the materials, the stability of the vehicle is reduced, and there is a risk of rollover at a slightly high speed, which exists a safety hazard.

[0031] Example 1

[0032] A transport bag that facilitates loading and unloading of materials, such as Figures 1-3 As shown, the system includes a double-layered bag made of elastic material, an inflation pipe 7 disposed between the double-layered bags, a fluidized bed mechanism, a fixing mechanism for fixing the double-layered bags, and a controller (not shown in the figure). The double-layered bag includes an inner bag 1 and an outer bag 2. The fluidized bed mechanism is fixed to the bottom of the inner bag. The fluidized bed mechanism includes at least one strip-shaped fluidized bed unit arranged longitudinally. In this embodiment, there are three fluidized bed units. Each fluidized bed unit includes at least two bellows 10 arranged in the front-back direction. In this embodiment, there are also three bellows. Each bellows is 6 meters long. In other embodiments, the length of the bellows can be set shorter or longer as needed, such as 4 meters, 8 meters, etc. The bellows have airtight flexible material on all sides and bottom. In this embodiment, the material used is airtight plastic sheet. The bellows have a top made of airtight flexible material, such as canvas and vulcanized cloth, which is breathable but does not leak material. The interior of the bellows and the interior of the inner bag are blocked by the top of the bellows. A spring net 1 made of springs is fixed inside each bellows. 1. In this embodiment, a cross-shaped spring mesh is formed by springs. The four sides of the spring mesh are fixed to the four sides of the air box. Each air box has an air inlet pipe 12 on both sides. The other end of each air inlet pipe is connected to an air pump (not shown in the figure) on the outside of the transport bag. Each air inlet pipe is controlled by an independent solenoid valve (not shown in the figure). The inflation pipe is connected to the air pump and has a solenoid valve (not shown in the figure). The fixing mechanism includes multiple sets of locking mechanisms fixed in the transverse direction to the inner surface of the bottom of the outer bag, and a locking mechanism for fixing the lower surface of the bottom of the inner bag. The locking mechanism includes multiple sets of hanging rings 3, multiple pull ropes 5 passing through the corresponding locking mechanism and hanging rings, and multiple winding motors 6 for winding and releasing the corresponding pull ropes. Each locking mechanism includes multiple locking mechanisms 4 arranged in the front-to-back direction. The controller is connected to each solenoid valve, each locking mechanism, and each winding motor. The connection method can be Bluetooth. The winding motors are powered from the outside of the double-layer bag. Each solenoid valve and locking mechanism is powered by a lithium battery or wired connection. In the wired connection method, the wires are sealed and passed through the outer layer of the bag.

[0033] The locking mechanism comprises a U-shaped clamping plate 401 and an electric push rod or electromagnetic lock arranged on one side of the clamping plate for passing through the U-shaped clamping opening. In the embodiment, the electromagnetic lock 402 is arranged in the clamping plate. The corresponding pull rope 5 passes through the clamping plate and is sleeved on the corresponding hanging ring 3 at the part of the U-shaped clamping opening. One end of the pull rope is fixed on the distal clamping plate, and the other end is wound on the corresponding winding motor 6. When the pull rope is pulled tight, the hanging ring is clamped into the corresponding U-shaped clamping opening, and the electric push rod or electromagnetic lock locks the hanging ring. The inner and outer bag bodies return to the loading state. The locking mechanism solves the corresponding locking relationship between the locking mechanism and the hanging ring.

[0034] A gas distribution box 9 is arranged between the double-layer bag bodies. Each air inlet pipe and inflation pipe is connected with the air pump through the gas distribution box, which is convenient for installation and control. Specifically, the gas distribution box is connected with the air pump through the air path 8 arranged on the outer bag body. Each electromagnetic valve is arranged on the air inlet pipe and inflation pipe around the gas distribution box 9. The air inlet pipe is a spring-shaped telescopic air inlet pipe, which can prevent the air inlet of the air inlet pipe from being pulled off from the bellows when the inner and outer bag bodies are separated and inflated.

[0035] A plurality of pairs of infrared sensors are arranged on the inner surface of the inner bag body in the vertical direction, or a pressure sensor is arranged on the top of the bellows. The controller is connected with the infrared sensors or the pressure sensor. The purpose is to detect the height or weight of the material. In the embodiment, the infrared sensor (not shown in the figure) is used in cooperation with the controller, electromagnetic valve and air pump to control the timing of the bellows operation and adjust the air outlet speed and pressure of the bellows, so as to prevent the material from being overblown to produce a large amount of smoke and dust or the air outlet speed and pressure from causing the material to be unable to be in a boiling state.

[0036] The transport bag of the present embodiment is convenient for loading and unloading. When in use, the outer side of the material bag is fixed in the carriage by hooks or electromagnets. The fixing structure and fixing method are prior art and will not be described here. When loading, the material is blown to boil by the air bellow, so that the material is self-leveling, and the efficiency is greatly improved. Before turning, the driver unlocks one or more sets of locking mechanisms on the bottom of the lateral side by the controller, controls the inflation tube to inflate between the inner and outer bag bodies, and controls the winding motor to release the restraint of the corresponding pull rope, so that the inner bag body on the outer side of the vehicle body is separated from the outer bag body and inflated, and the material is driven to the center of the turn, the center of gravity of the vehicle body moves inward, helping the vehicle body to turn, and preventing the vehicle body from turning over. When unloading, the air bellow is controlled to boil the material to facilitate unloading. At the same time, the controller controls the locking mechanism to unlock the corresponding hanging ring, and the control strategy is to unlock from far to near successively, and at the same time, the inflation tube is inflated between the inner and outer bag bodies, and the winding motor is controlled to release the restraint of the corresponding pull rope, so that the inner bag body and the outer bag body are separated from each other and inflated successively, the material is pushed to the unloading pipe head or the unloading port, until the unloading is clean, which is very ingenious. The spring net not only ensures the space of the air bellow and the air inlet pipe, but also blocks and disperses the gas filled in the air bellow evenly, so that the gas out of the air bellow is relatively uniform.

[0038] The loading method using the transport bag comprises the following steps:

[0039] Step 1, loading through the loading pipe, when the material below the loading port 13 reaches a certain height, the controller controls the air pump and the corresponding electromagnetic valve to send gas to the air bellow below the loading port to boil the material.

[0040] Step 2, the other air bellows start to run after the material reaches the set height until the loading is completed.

[0041] Preferably, each air bellow adjusts the gas outlet speed and pressure according to the different heights of the material by adjusting the air pump pressure, the opening degree of the electromagnetic valve and / or the single or double side gas supply mode, so as to ensure that the material is limited to the boiling state.

[0042] Embodiment 3

[0043] The unloading method using the transport bag comprises the following steps:

[0044] Step 1, while sucking through the unloading pipe head or unloading through the unloading port, the controller controls the air pump and the electromagnetic valve to send gas to each air bellow to boil the material, which facilitates the suction of the unloading pipe head or the unloading through the unloading port, and moves the material away from the unloading pipe head or the unloading port to the unloading pipe head or the unloading port.

[0045] Step 2, when the material depth in the transport bag is detected to be reduced to the set depth by the optical sensor or the pressure sensor, the controller controls the locking mechanism to unlock the corresponding hanging ring, the control strategy is to unlock from far to near to the discharge pipe head or discharge port, at the same time, the controller controls the inflation pipe to inflate between the inner and outer bag bodies, and controls the winding motor to release the corresponding pull rope, so that the inner and outer bag bodies are gradually separated and inflated, and the material is pushed to the discharge pipe head or discharge port until the discharge is completed.

[0046] After the unloading is completed, the controller controls each winding motor to tighten the corresponding pull rope, so that the hanging ring enters the corresponding locking mechanism, the controller controls each locking mechanism to lock the pull ring, and the loading function of the transport bag is restored.

[0047] The above only describes the preferred embodiments of the present application and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
