Description

[0002] The mixing, extrusion, and granulation unit can mix, plasticize, extrude, pelletize, separate, and dry materials, ultimately processing them into regular granular products. The feed hopper is used to feed materials to the melt mixing system within the mixing, extrusion, and granulation unit. It serves as a buffer container before the raw materials enter the melt mixing system and also plays a role in initial mixing with additives. It is necessary to ensure that the feed hopper always contains a certain amount of raw materials to avoid discontinuous raw materials entering the melt mixing system, resulting in substandard finished particles. However, existing feed hoppers are difficult to achieve continuous automatic feeding, and the discharge channel between the feed hopper and the melt mixing system is difficult to install and adjust, which easily leads to material sedimentation. Utility Model Content

[0003] In order to solve the problem that the existing feeding bin is difficult to achieve continuous automatic feeding and is prone to material deposition, the utility model provides a continuous feeding bin with a soft connection.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: a continuous feeding silo with a soft connection, comprising a cylindrical silo, the side wall of the silo is connected to a feeding pipe, the feeding pipe is inclined and the top end is connected to a feeding hose, the bottom of the silo is provided with a gradient section, the small end of the gradient section is downward and is provided with a long strip of discharge port, the discharge port is connected to the external equipment below the silo through a canvas soft connection, the side wall of the gradient section is provided with an observation window and is connected to a nitrogen purge pipe, the nitrogen purge pipe can blow away the material covering the observation window in the silo, the end cover at the top of the silo is connected to an exhaust hose, the end cover is also provided with an additive inlet and a high-level material level gauge installation port, the side wall of the gradient section is also provided with a manual discharge port and a low-level material level gauge installation port, the high-level material level gauge installation port and the low-level material level gauge installation port are respectively provided with a material level gauge extending into the silo;

[0005] The canvas flexible connection includes an upper flange installed at the discharge port and a lower flange installed at the external equipment. The inner hole of the upper flange is welded to the top end of the liner barrel section. Two mounting barrel sections are sleeved on the outer side of the liner barrel section. The two mounting barrel sections are respectively connected to the upper flange and the lower flange. The outer sides of the two mounting barrel sections are matched with canvas covers. The top and bottom sides of the canvas covers are respectively tied and connected to the two mounting barrel sections by cable ties. The canvas cover can stretch or wrinkle along the axial direction of the liner barrel section. There is an annular space between the outer wall of the liner barrel section and the inner wall of the mounting barrel section located below, so that the liner barrel section can float axially and radially relative to the external equipment below the silo.

[0006] Preferably, the side wall of the gradual transition section of the silo is further provided with a reserved opening.

[0007] According to the above technical solution, the beneficial effects of the utility model are:

[0008] The continuous feeding bin of the present invention is equipped with a high-level material level meter and a low-level material level meter on the upper and lower sides respectively. When the high-level material level meter triggers a signal, it indicates that the material in the bin has accumulated to a sufficient height. At this time, a signal can be sent to the external material conveying device to stop feeding into the feeding pipe. When the low-level material level meter triggers a signal, it indicates that the material in the bin has been consumed to the height required for feeding. At this time, feeding into the feeding pipe can be restarted to achieve automatically controlled cyclic feeding. The canvas flexible connection of the present invention can achieve axial and radial floating, which is convenient for installation and adjustment of the feeding bin and the melt mixing system. The outer layer of the flexible connection is soft and easy to install. The upper part of the inner metal bushing is integrated with the flange and the lower part is suspended, which prevents the raw material from eroding the soft outer layer and can effectively prevent material deposition.
