Description
Technical Field
The utility model relates to a powder transportation/storage field, specific powder compression loading device of unrestrained packing in transport tank car in bulk that says so.
Background
The existing powder, especially light powder such as calcium hydroxide, often has the problem of low space utilization rate in transportation and storage, and the transportation mode of the light powder by a tank truck is taken as an example: when the tank car is used for transporting materials with larger bulk density, the tank car is limited by allowable bearing mass; however, when transporting light powder, the bulk density of the light powder is low, so that the volume of the powder after being filled reaches the upper limit of tank car transportation in the transportation process of the tank car, and the weight of the powder is far lower than the upper limit of the load when the powder is transported by the tank car. This is because the light powder can form a layer of air film between powder particles in the process of filling the powder into the tank car. The gas film is difficult to remove by conventional methods due to the physical properties of the light powder, and usually takes more than 20 hours to remove by standing. Therefore, the transportation capacity is wasted, and the transportation cost in the transportation process is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a powder compression loading attachment of unrestrained packing in the transportation tank car in bulk improves the packing density and the loading capacity of light powder, reduces the cost of transportation of light powder.
In order to solve the technical problem, the utility model discloses a specific scheme do: the powder compressing and filling device for the unconstrained package in the bulk transport tank truck comprises a negative pressure pipe and a pulse pipe, wherein the negative pressure pipe is connected with a vacuum pump through a valve, and the pulse pipe is connected with the atmosphere through a pulse electromagnetic valve.
Preferably, the negative pressure pipe is connected with the vacuum pump through a flexible exhaust pipe, and the valve is arranged on the exhaust pipe.
Preferably, the negative pressure pipe is provided with a filter element for preventing the powder from being extracted out through the negative pressure pipe.
Preferably, the negative pressure pipe and the pulse pipe are fixed on the same sealing disc at intervals, and a flange used for being connected with a tank car is arranged on the periphery of the sealing disc.
Preferably, the negative pressure pipe and the pulse pipe are distributed in parallel.
The utility model discloses can carry out the quick compression with the powder in the tank car, utilize the space of practicing thrift out after the compression to load once more to improve transportation and storage efficiency with this, practice thrift the cost.
The utility model discloses can solve the higher light mass powder of fineness super volume but not overweight problem when the tank car transports, can realize that "high density" in the tank car loads. This has the advantage that no additional constraint of film or other material is required during compression. The time consumption of compression is short, and the single compression amount is large. Meanwhile, the volume-mass ratio in the transportation process can be considered after compression, so that the transportation cost waste caused by the fact that the transportation process is hollow and has volume but no mass is avoided.
Taking the tank car transportation as an example, compared with the prior common filling method, the utility model can fill about 25 percent more materials, thereby reducing about 25 percent of the transportation cost of the light powder during transportation.

Detailed Description
As shown in fig. 1 and 2, the powder compressing and filling device for unconstrained packaging in a bulk transport tank truck of the present embodiment is used for matching with a tank truck 2. The tank truck 2 is provided with a filling port 1 for filling the powder 4 and a mounting port 3 for fitting the present embodiment, and the present embodiment includes a sealing disk 9 mounted on the mounting port 3 via a flange and a gasket, and a negative pressure tube 8 and a pulse tube 7 disposed on the sealing disk 9 at an interval.
The negative pressure pipes 8 are vertically distributed and used for pumping air in the inner cavity of the tank truck 2 to form vacuum in the tank truck 2. The upper end of the vacuum pump is connected with a vacuum pump (not shown in the figure) through an air exhaust hose, and the air exhaust hose is provided with a valve (not shown in the figure) for controlling the negative pressure exhaust state; the lower part of the filter disc extends into the inner cavity of the tank car 2 after passing through the sealing disc 9 and is connected with a filter element 5, so that the powder 4 in the tank car 2 is prevented from being pumped out by a vacuum pump through the filter element 5.
The pulse pipes 7 are also distributed along the vertical direction, the lower ends of the pulse pipes are communicated with the inner cavity of the tank car 2, the upper ends of the pulse pipes are communicated with the outside atmosphere, and pulse electromagnetic valves 6 are arranged on the pulse pipes 7. The pulse electromagnetic valve 6 is used for re-introducing the outside air into the inner cavity of the tank car 2 in an interval pulse mode after vacuum is formed in the tank car 2 so as to achieve the effect of rapping the top layer of the powder in the tank car 2 to form the compact layer 10.
The specific implementation method of this embodiment is as follows:
after about 75% volume fraction of the powder 4 is filled in the tank truck 2 as shown in fig. 1, the sealing disc 9 is installed at the installation port 3 as shown in fig. 2, and the vacuum pump connected to the negative pressure pipe 8 is started to pump the pressure in the whole tank truck 2 to about-0.06 Mpa. At this time, the gas remaining among the light powder 4 particles overflows the top of the material layer, so that the stacking volume of the powder 4 in the tank car 2 is increased, and a certain 'fluidization leveling' phenomenon is generated.
After the fluidization is completed, the negative pressure pipe 8 is closed and then the pulse solenoid valve 6 is actuated as shown in fig. 3. At this time, the external air forms pulse airflow through the pulse electromagnetic valve 6 according to the set pulse interval (0.5-1S) and pulse length (0.05-0.1S) to directly hammer the surface layer of the powder 4, and the rapping action of the surface layer for 10S is carried out, so that a dense layer 10 is formed on the surface layer of the powder 4.
After the dense layer 10 is formed, as shown in fig. 4, the pulse electromagnetic valve 6 is completely opened, so that the inner cavity of the tank car 2 is communicated with the external air pressure through the pulse pipe 7. At this time, the compact layer 10 is used for boundary, the air pressure of the material below the compact layer 10 is small, the pressure at the upper part of the compact layer 10 is large, and the compact layer 10 is pressed to descend by the pressure generated by the pressure difference between the upper side and the lower side of the compact layer 10 by utilizing the principle that the compact layer 10 is airtight, so that the powder 4 is forced to be compressed automatically, and the purpose of compressing the volume of the powder 4 in the tank is achieved.
In addition, except that the loading of above-mentioned powder 4 in tank car 2, according to above device and utility model's principle, the utility model discloses still can be applied to in the storage vat in the bucket of light powder 4 compression, the feed bin in the storehouse of light powder 4 compression and the light powder 4 volume compression under the no packing restraint condition etc. do not give unnecessary details here.
