Description

Technical Field

[0001] The utility model relates to the technical field of vacuum loading bins, in particular to a vacuum loading bin used for material transportation. Background Art

[0002] The vacuum feeder is mainly a vacuum conveying equipment for powdered materials, granular materials, and powder-granular mixtures. The equipment can directly convey the mixed materials into the mixer, thereby greatly reducing the labor intensity of the workers. Therefore, it has been favored by many industrial equipment manufacturers. Its working principle is to use a vacuum pump to generate a vacuum, and the negative pressure generated by the vacuum sucks the material from the feed port. Then the air and the material are separated in the filter bin of the separation container. The material falls automatically due to gravity, and the material is collected in the silo. In the existing vacuum feeding silo, some fine materials are not blocked by the filter screen during the extraction process. The material will be extracted by the vacuum pump and taken out of the feeding silo, which can easily cause material waste. At the same time, it is difficult to use and the effect is not very good.

[0003] In order to solve the above technical problems, the Chinese utility model patent with the authorization announcement number CN217626349U discloses an improved vacuum feeding silo, which is provided by installing a conical filter cartridge inside the feeding silo body, and the air inlet pipe on the conical filter cartridge is connected with the delivery pipe on the vacuum pump. When the vacuum pump is working, the air extraction head extracts the air inside the feeding silo body, and the fine particles will pass through the filter screen and enter the vacuum pump, and then be transported from the delivery pipe to the air inlet pipe and enter the inside of the conical filter cartridge. The fine materials and gas enter the conical filter cartridge along the tangential direction. Under the design of the inclined inner wall, the airflow rotates from top to bottom. During the rotation process, the fine materials are thrown to the periphery because of their greater density than the gas and the greater centrifugal force they are subjected to. They are discharged from the bottom along the inner wall under the combined action of the downward airflow and gravity and enter the inside of the feeding silo body, while the clean airflow is led upward from the center of the conical filter cartridge and finally discharged from the air outlet pipe, thereby achieving the effect of purifying the gas, and at the same time, the material will not be wasted.

[0004] Although the technical solution provided by the utility model solves the problem that the existing vacuum loading silo is prone to material waste when in use, the pipeline used to extract materials in the above solution is connected to the feed connecting pipe in the vacuum loading silo by plugging. Although the plug-in method can improve the connection efficiency of the pipeline, this connection method will cause the connection to be loose, and the pipeline may fall off during the material extraction process, affecting normal use. Utility Model Content

[0005] The purpose of the utility model is to provide a vacuum loading bin for material transportation to solve the problems raised in the above background technology.

[0006] The present application embodiment adopts the following technical solutions:

[0007] A vacuum loading silo for material conveying comprises a loading silo body, a sealing cover is installed on the top of the loading silo body, a fixed base is arranged below the loading silo body, a discharge pipe is fixedly connected to one side of the loading silo body, a discharge end of the discharge pipe is connected to a connecting pipe, the upper and lower sides of the connecting pipe are hinged with limit plates, the limit plates are composed of an L-shaped plate and a straight plate, a limit groove matched with the limit plate is opened on the discharge pipe, and the limit plate is detachably arranged in the limit groove.

[0008] Beneficial effects:

[0009] The utility model provides a limiting groove on the discharge pipe. After the connecting pipe is initially connected to the discharge pipe, the limiting plate on the connecting pipe is flipped over and the limiting plate is flipped into the limiting groove, thereby limiting the connecting pipe and preventing the connecting pipe from falling off during use, thereby ensuring the stability of the pipe after connection.

Through the matching setting between the limit plate 8 and the limit groove 9, the connecting pipe 5 can be limited to prevent the connecting pipe 5 from falling off during use;

[0021] The upper and lower sides of the connecting pipe 5 are fixedly installed with hinge seats 6, and the limit plate 8 is hinged on the hinge seat 6 through the hinge shaft 7. A torsion spring is arranged between the hinge shaft 7 and the limit plate 8. By providing the torsion spring, when the internal thread column 15 is retracted from the plug-in groove 17, the limit plate 8 can be automatically popped out from the limit groove 9 by the elastic force of the torsion spring.
