Description

Technical Field

[0001] The utility model relates to a powder storage bin, specifically a powder anti-blocking feeding device installed at the bottom of the powder storage bin. Background Technique

[0002] During the production process in factories, various large powder storage bins often have the situation that the powder is blocked in the hopper, resulting in poor powder feeding and affecting production. Through observation and research, it is found that the reason for the frequent blockage of large powder storage bins is that due to the large volume of large powder storage bins, the installation space is limited, the inclination angle of the hopper is insufficient, and the vibration motor has limited vibration effect on large powder storage bins, resulting in the powder being unable to slide smoothly along the inclined wall of the powder storage bin; at the same time, due to the need for external transportation and filling, the outlet of the large powder storage bin is small, and the powder is easily congested at the outlet. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the above background technique, and provide a powder anti-blocking feeding device, so that the powder can smoothly feed from the hopper to the outlet, to solve the problem of blockage of large powder storage bins and ensure normal production.

[0004] The technical solution provided by the utility model is: a powder anti-blocking feeding device, including an air cannon and several vibrators; characterized in that; the powder anti-blocking feeding device further includes a vibrating hopper installed at the bottom of the powder storage bin and in a funnel shape, the air cannon and several vibrators are all installed outside the vibrating hopper, and the muzzle of the air cannon sequentially passes through the vibrating hopper and the wall of the powder storage bin and extends into the powder storage bin to eliminate the blockage phenomenon of the powder storage bin.

[0005] The vibrating hopper is installed at the bottom of the powder storage bin through an expansion joint, and the upper flange and the lower flange of the expansion joint are respectively welded to the powder storage bin and the vibrating hopper.

[0006] The upper flange of the expansion joint and the powder storage bin are welded and connected through several uniformly arranged reinforcing rib plates.

[0007] The outlet of the powder storage bin and the outlet of the vibrating hopper are vertically corresponding, and the diameter of the outlet of the powder storage bin is at least 1.5 times larger than the diameter of the outlet of the vibrating hopper; at the same time, the diameter of the outlet of the vibrating hopper is the same as the diameter of the outlet of the powder storage bin before improvement.

[0008] The taper of the vibrating hopper is the same as the taper of the powder storage bin.

[0009] The beneficial effects of the present utility model are as follows: The device is installed at the bottom of a large-scale powder storage bin. The expansion joint in the device has the characteristic of being telescopic, and the frequent vibration of the vibrating hopper is not likely to cause damage to the expansion joint. The vibrating hopper can be regarded as the hopper of the powder storage bin and is arranged in sections. The vibrating hopper is small in volume, and the effect of the vibrating motor is significant. Coupled with the arch-breaking effect of the air cannon, the material discharging is smoother, thereby achieving the purpose of preventing blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following is further described in conjunction with the embodiments shown in the drawings.

[0015] The powder anti-blocking material discharging device shown in the drawings includes an air cannon 5 and a plurality of vibrators 4 installed on the powder storage bin 7; this is similar to the structure of the existing anti-blocking material discharging device (see Figure 3 ).

[0016] The improvement of the present utility model is that the powder anti-blocking material discharging device further includes a vibrating hopper 7 in a funnel shape, and the vibrating hopper is installed at the bottom of the powder storage bin; the taper of the vibrating hopper is the same as that of the powder storage bin.

[0017] The vibrator is preferably an eccentric motor vibrator and is installed outside the vibrating hopper through the vibrating motor mounting seat 3. The air cannon is installed outside the vibrating hopper through the air cannon mounting seat 6, and the muzzle of the air cannon also extends into the powder storage bin through the walls of the vibrating hopper and the powder storage bin in sequence to be used for eliminating the phenomenon of powder bin blockage; an external compressed air source (preferably an air pump) is connected to the intake pipe of the air cannon through the air cannon intake flexible pipe 9.

[0018] The vibrating hopper is installed at the bottom of the powder storage bin through an expansion joint 1; the upper flange of the expansion joint is welded to the powder storage bin, and the lower flange of the expansion joint is welded to the vibrating hopper;

[0019] Further, the upper flange of the expansion joint and the powder storage bin are welded and connected by a plurality of reinforcing rib plates 8. The plurality of reinforcing rib plates are uniformly arranged along the circumferential direction, so as to firmly connect the expansion joint and the powder storage bin and ensure that they will not come apart during vibration.

[0020] The outlet diameter of the vibrating hopper is the same as that of the powder storage bin before improvement (i.e., the same as the outlet diameter of the existing powder storage bin); the outlet of the powder storage bin and the outlet of the vibrating hopper are vertically corresponding, and the outlet diameter of the powder storage bin is at least 1.5 times (preferably 1.5 times) larger than the outlet diameter of the vibrating hopper; in this way, it can be made that...
