Description

Technical Field

[0001] The invention relates to the technical field of slurry conveying and packaging, in particular to a slurry canning device and a canning method. Background Art

[0002] When filling existing slurry packaging barrels, the feed port of the barrel is directly connected to the pipe thread for filling. This leads to the problem that the air in the packaging barrel cannot be discharged in time during filling, which poses a great safety hazard for toxic and flammable gases, and cannot meet the requirements of accurate weight during weighing and metering. Existing filling devices basically use metal hoses as guide tubes for feeding, but during the feeding process, the impact force of material discharge will cause the stationary metal hoses to swing, thereby affecting the weighing. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a slurry filling device which can accurately weigh and fill with protective gas for protection during the feeding process in view of the deficiencies in the prior art.

[0004] The technical problem to be solved by the present invention is achieved through the following technical scheme. The present invention is a slurry canning device, which is characterized in that it includes a slurry packaging barrel, the slurry packaging barrel is provided with an opening, and a sealed exhaust cylinder is installed above the opening; the sealed exhaust cylinder includes an exhaust cavity and a sealing device, the top of the sealing device is provided with an exhaust hole communicating with the exhaust cavity, the exhaust cavity is provided with an air inlet pipe passing through the exhaust cavity and then entering the slurry packaging barrel through the opening, and a feed pipe extending into the slurry packaging barrel is installed in the air inlet pipe; the top of the sealing device is also provided with an air inlet hole communicating with the air inlet pipe, and an exhaust channel communicating with the exhaust cavity is provided between the outer wall of the air inlet pipe and the outer wall of the opening of the slurry packaging barrel.

[0006] The technical problem to be solved by the present invention can be further achieved by the following technical solution: the feed pipe and the air inlet pipe are both curved pipes extending from the bottom toward the wall of the slurry packaging barrel.

[0007] The technical problem to be solved by the present invention can be further achieved by the following technical solution: the bending angle of the bent pipe is 90°-160°.

[0008] The technical problem to be solved by the present invention can be further achieved by the following technical solution: an air vent is provided at the bottom of the air inlet pipe.

[0009] The technical problem to be solved by the present invention can be further achieved by the following technical solution: the width of the exhaust channel is 1 cm-5 cm.

[0010] The technical problem to be solved by the present invention can be further achieved by the following technical solution: a quick-release joint capable of suspending the slurry tank filling device at the opening is provided at the feed inlet of the feed pipe.

[0011] The technical problem to be solved by the present invention can be further achieved by the following technical solution: the opening of the slurry packaging barrel is located at the outer edge of the center position of the packaging barrel.

[0012] A method for canning slurry using the above-mentioned slurry canning device comprises the following steps:

[0014] (2) Open the air inlet of the slurry filling device and fill the packaging barrel with protective gas through the air inlet pipe;

[0015] (3) The slurry rushes toward the barrel wall through the elbow of the feed pipe and flows down along the barrel wall, ensuring that there is no splashing of the slurry and the accuracy of weighing and measuring during the feeding process; when the slurry enters the packaging barrel, part of the protective gas is sprayed onto the barrel wall at the point where the slurry falls through the outer ring of the feed pipe, and the other part enters the barrel through the air vent under the elbow;

[0016] (4) The protective gas enters the bottom of the barrel under the impact force of 3Mpa-6Mpa. The air and other gases enter the exhaust chamber along the exhaust channel between the outer wall of the air inlet pipe and the outer wall of the opening of the slurry packaging barrel, and are discharged from the exhaust port on the exhaust chamber to the exhaust gas treatment equipment for treatment, forming a closed gas protection system.

[0023] The specific technical solutions of the present invention are further described below to help those skilled in the art further understand the present invention, but do not constitute a limitation on the rights thereof.

[0024] Reference Figure 1-Figure 2 A slurry canning device comprises a slurry packaging barrel, the slurry packaging barrel is provided with an opening, and a sealed exhaust cylinder is installed above the opening; the sealed exhaust cylinder comprises an exhaust cavity and a sealing device, the top of the sealing device is provided with an exhaust hole 6 communicating with the exhaust cavity, the exhaust cavity is provided with an air inlet pipe 4 passing through the exhaust cavity and then entering the slurry packaging barrel through the opening, and a feed pipe 2 extending into the slurry packaging barrel is installed in the air inlet pipe; the top of the sealing device is also provided with an air inlet hole 3 communicating with the air inlet pipe, and an exhaust channel 10 communicating with the exhaust cavity is provided between the outer wall of the air inlet pipe and the outer wall of the opening of the slurry packaging barrel.

[0025] The sealing device comprises an upper magnetic ring sleeve 7 adsorbed on the top of the air inlet pipe and a lower magnetic ring sleeve 8 adsorbed on the outer side of the opening of the slurry packaging barrel, and a silicone hose 5 for sealing the exhaust cavity is arranged between the upper magnetic ring sleeve and the lower magnetic ring sleeve.

[0026] The feed pipe and the air inlet pipe are both curved pipes extending from the bottom toward the wall side of the slurry packaging barrel.

[0027] The bending angle of the bent pipe is 90°-160°.

[0028] An air vent 9 is provided at the bottom of the air inlet pipe.

[0029] The width of the exhaust channel 10 is 1 cm-5 cm.

[0030] The feed inlet of the feed pipe is provided with a quick-release joint 1 which can suspend the slurry tank device at the opening.

[0031] The opening of the slurry packaging barrel is located at the outer edge of the center position of the packaging barrel.

[0032] A method for canning slurry using the above-mentioned slurry canning device comprises the following steps:

[0033] (1) Connect the quick-release joint of the slurry filling device to the upper container, ensure that the filling device is suspended at the opening of the packaging barrel, fine-tune the air inlet pipe to ensure that there is no contact between the opening of the packaging barrel, and install the sealing device on the outside of the exhaust chamber before starting to feed the material, so that the exhaust chamber is in a sealed state;

[0034] (2) Open the air inlet of the slurry filling device and fill the packaging barrel with protective gas through the air inlet pipe;

[0035] (3) The slurry rushes toward the barrel wall through the elbow of the feed pipe and flows down along the barrel wall, ensuring that there is no splashing of the slurry and the accuracy of weighing and measuring during the feeding process; when the slurry enters the packaging barrel, part of the protective gas is sprayed onto the barrel wall at the point where the slurry falls through the outer ring of the feed pipe, and the other part enters the barrel through the air vent under the elbow;

[0036] (4) The protective gas enters the bottom of the barrel under the impact force of 3Mpa-6Mpa. The air and other gases enter the exhaust chamber along the exhaust channel between the outer wall of the air inlet pipe and the outer wall of the opening of the slurry packaging barrel, and are discharged from the exhaust port on the exhaust chamber to the exhaust gas treatment equipment for treatment, forming a closed gas protection system.

[0037] The present invention is applicable to various slurry canning requirements, especially the canning of toxic and volatile slurries in a confined space. The specific operation of the device when in use is as follows:

[0038] First, insert the slurry canning device into the packaging barrel, align the quick-release connector 1 with the container storing the slurry and connect them, ensure that the slurry canning device is suspended at the feed port, and then fine-tune the feed port of the packaging barrel and the feed pipe 2 of the device to ensure that there is no contact between them. Before the start of feeding, the upper magnetic ring sleeve 7 and the lower magnetic ring sleeve 8 are adsorbed on the wall tube and the packaging barrel respectively, and the nitrogen inlet ball valve is opened to let nitrogen in, reducing the safety hazards when releasing the slurry. The slurry rushes to the barrel wall through the bent part of the feed pipe 2, and flows down along the barrel wall, ensuring that there is no splashing of the slurry and ensuring the accuracy of weighing and metering during the feeding process. When the charging protective gas is nitrogen, the slurry enters the barrel, and part of the nitrogen protective gas is sprayed onto the barrel wall where the slurry falls through the outer ring of the feed pipe, and the other part enters the barrel through the air vent 9 of the bent part. Since the weight of the air in the barrel is basically the same as that of the nitrogen, the nitrogen enters the bottom of the barrel under the impact of 3Mpa-6Mpa. At the same time, the air and other gases enter the sealing area of ​​the upper and lower magnetic ring sleeves along the gap at the barrel mouth, and are discharged to the exhaust gas treatment equipment through the exhaust hole 6 for treatment, effectively blocking the gas leakage to form a closed gas protection system.
