Description

Technical Field

[0001] The utility model relates to the field of silos, and in particular to a silo with an auxiliary material discharge structure and powder material processing equipment. Background Art

[0002] At present, the application of powder materials is becoming more and more extensive. Some powder materials are relatively sticky and have small particle sizes. Such powder materials are easy to agglomerate in the silo, which may affect the continuity of material feeding and further affect the continuity of production.

[0003] How to improve the continuity of feeding of easily agglomerated powder materials has always been a difficult problem in the powder processing and production process. In some existing technologies, a vibration device is set on the outer wall of the silo, and the continuity of feeding of the silo is improved by knocking the outer wall of the silo by the vibration device. However, this method is noisy, affects the production environment, and is not conducive to the health of operators; on the other hand, the silo is knocked for a long time, and the knocking position is relatively fixed, which is easy to cause local damage to the silo, thereby shortening the life of the silo.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0031] First embodiment

[0032] Please refer to Figure 1 and Figure 2 The present embodiment provides a silo with an auxiliary material discharge structure, including a silo body 100, wherein a stirring blade 200 is arranged inside the silo body 100, and a connecting rod 300 is connected to the stirring blade 200, and the other end of the connecting rod 300 passes through the side wall of the silo body 100 and is connected to a vibration generating device 400, and the position of the vibration generating device 400 is relatively fixed to the silo body 100, and a movable connecting piece is arranged between the connecting rod 300 and the side wall of the silo body 100.

[0033] In the embodiment of the utility model, the vibration generating device 400 is arranged outside the silo, which can avoid oil leakage and debris generated by the vibration generating device from polluting the powder material, and is suitable for working conditions with high requirements for material purity. The vibration generating device 400 drives the stirring blade 200 arranged inside the silo to vibrate, so that the power is directly applied to the powder material in the silo, which is more conducive to improving the utilization rate of energy.

[0034] In this embodiment, the vibration of the stirring blade 200 can, on the one hand, act on the agglomerated and lumped materials, causing the agglomerated and lumped materials to be broken up and reducing the probability of the silo outlet being blocked; on the other hand, the vibration of the stirring blade 200 can also play a role in promoting the materials, which is also beneficial to reduce the probability of the silo outlet being blocked and improve the continuity of material discharge.

[0035] It should be noted that the stirring blade 200 in this embodiment is located inside the silo body 100 and the vibration generating device 400 is located outside the silo body 100. Therefore, the connecting rod 300 needs to pass through the silo body 100. This only requires a movable connecting piece to be set between the connecting rod 300 and the silo body 100. On the one hand, the movable connecting piece can support the connecting rod 300, and on the other hand, it will not affect the movement of the connecting rod 300. At the same time, it can reduce the rigid collision or friction generated when the connecting rod 300 is directly connected to the side wall of the silo body 100, which is beneficial to reduce the increase in impurity content caused by the introduction of friction debris in the powder material.

[0036] The power generation structure of the power generation component of the vibration generating device 400 in this embodiment can be a pneumatic element, or an electromagnetic device, a motor driving structure, etc.

[0037] In an optional embodiment, the movable connecting member includes an elastic sealing member 500 , and the elastic sealing member 500 is provided with a through hole for the connecting rod 300 to pass through.

[0038] The elastic seal 500 may be an elastic sleeve or an elastic ring, and the material may be rubber or other elastic materials. The existence of the elastic seal 500 can support the connecting rod 300 without affecting the movement of the connecting rod 300, and at the same time can fill the gap between the connecting rod 300 and the silo body 100 to avoid material leakage.

[0039] In an optional embodiment, a mounting opening is provided on the side wall of the silo body 100, a first mounting ring is provided on the mounting opening, and a second mounting ring is provided on the elastic seal 500 that can cooperate with the first mounting ring to fix the elastic seal 500 in the mounting opening.

[0040] If the elastic seal 500 is directly inserted into the installation port, the connection stability between the two is poor due to the simple friction force. Under the support of the vibration generating device 400, the elastic seal 500 will soon detach from the installation port, resulting in the elastic seal 500 being unable to support the connecting rod 300 and seal the silo body 100. Therefore, a first connecting ring and a second connecting ring are respectively installed on the installation port and the elastic seal 500 to form an installation structure 800, and the elastic seal 500 is installed and fixed through the cooperation of the first connecting ring and the second connecting ring.

[0041] It should be noted that, in this embodiment, there is no restriction on the fixing method between the first connecting ring and the mounting port, or the fixing method between the second connecting ring and the elastic seal 500. For example, the first connecting ring and the mounting port can be connected by threaded connection, crimping or interference fit; a groove can be set in the inner ring of the second connecting ring, and the elastic seal 500 is set in the groove to achieve fixation of the two, or the second connecting ring is crimped onto the elastic seal 500.

[0042] In an optional embodiment, the first mounting ring and the second mounting ring are interference fit.

[0043] In some embodiments, the first mounting ring and the second mounting ring may be connected by snap-fitting, threaded connection or other methods. Interference fit connection is beneficial to improving assembly speed.

[0044] In an optional embodiment, the connecting rod 300 is connected to the power output shaft 410 of the vibration generating device 400 through a universal ball joint 600. The connecting rod 300 and the power output shaft 410 of the vibration generating device 400 are connected through a universal ball joint, so that the movement of the connecting rod 300 is more flexible.

[0045] In an optional embodiment, a bracket 700 is provided on the silo body 100 , and the vibration generating device 400 is fixed on the bracket 700 .

[0046] In an optional embodiment, the distance between the stirring blade 200 and the side wall of the silo body 100 is less than 50 mm.

[0047] When the powder material agglomerates and clumps seriously, the distance between the stirring blade 200 and the side wall of the silo body 100 can be slightly larger; when the powder material agglomerates and clumps less, the distance between the stirring blade 200 and the side wall of the silo body 100 can be relatively small, which is beneficial to improve the continuity of silo unloading, and at the same time is beneficial to improve the service life of the connecting rod 300, and further helps to improve the continuity of silo discharging.

[0048] In an optional embodiment, a conical channel is provided at the bottom of the silo body 100, and the stirring blade 200 is disposed in the conical channel.

[0049] In some embodiments, the stirring blade 200, driven by the vibration generating device 400, moves in a direction almost parallel to the generatrix of the inner wall of the silo body 100. While breaking up the agglomerated and lumped materials, it can also reduce the adhesion of powder to the inner wall of the silo, which is more conducive to improving the continuity of the silo discharge.

[0050] In an optional embodiment, there are more than two stirring blades 200, and the shape of each stirring blade 200 can be optionally a rod-shaped blade, a perforated blade or a knife-shaped blade.

[0051] Specifically, in some embodiments, two stirring blades 200 may be disposed on the same connecting rod 300;

[0052] In other embodiments, each stirring blade 200 may correspond to a connecting rod 300 and a vibration generating device 400, and more than two stirring blades 200 are relatively evenly distributed on the inner wall of the silo;

[0053] In some other embodiments, each stirring blade 200 may correspond to a connecting rod 300 and a vibration generating device 400, and more than two stirring blades 200 are evenly arranged on the inner wall of the silo along the circumference of the silo.

[0054] In an optional embodiment, the surface of the stirring blade 200 and / or the connecting rod 300 is provided with a protective coating.

[0055] The protective coating can improve the wear resistance of the stirring blade 200 and the connecting rod 300. On the one hand, it can increase the service life of the stirring blade 200 and the connecting rod 300. On the other hand, it can reduce the wear debris entering the powder material and increase the impurity content in the powder material.

[0058] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
