Description

Technical Field

[0001] This utility model belongs to the technical field of metal powder production equipment, and relates to an improved discharge device for a metal powder silo. Background Technology

[0002] In order to avoid oxidation during the processing of metal powder, the material must be dried. After drying, the material must be temporarily stored in a storage silo before entering the next processing step.

[0003] In the existing technology, because the copper powder in the storage bin is arranged very densely after being accumulated in large quantities, it is very difficult for the feeding machine to suck the copper powder out from the bottom of the storage bin, and a lot of power is required.

[0004] The applicant previously proposed an original device with patent number "CN202121921550.9" entitled "An auxiliary discharge component for a metal powder silo" to solve the above problems.

[0005] After several years of application, the applicant discovered a major problem with the solution: the effect of the downward auxiliary discharge was significantly less than the effect of the upward push to prevent blockage. In other words, the auxiliary discharge function was actually interfered with by the anti-blocking function, resulting in poor auxiliary discharge performance. This was because the anti-blocking function used four counter-rotating screws, while the auxiliary discharge function only used one forward-rotating screw. This 1:4 difference resulted in very low efficiency improvement from the auxiliary discharge.

[0006] Therefore, this application is based on improvements made to the original device. Summary of the Invention

[0007] The purpose of this invention is to address the problem of low discharge efficiency of existing auxiliary discharge components for metal powder, and to propose an improved discharge device for metal powder silos.

[0008] The objective of this utility model can be achieved through the following technical solutions:

[0009] An improved discharge device for a metal powder silo is characterized by comprising a cross-shaped frame for fixing to a support on the inner wall of the silo, a reverse turntable rotatably disposed below the center of the cross-shaped frame, four forward turntables rotatably disposed below the four sides of the cross-shaped frame, a helical rod disposed below both the forward and reverse turntables, a forward drive element for driving the forward turntables to rotate forward and a reverse drive element for driving the reverse turntables of the cross-shaped frame to rotate in reverse on the cross-shaped frame, a flow divider at the bottom of the silo, four flow divider holes symmetrically opened at the center of the flow divider, and the four forward turntables and the four flow divider holes being vertically aligned.

[0010] In the aforementioned improved discharge device for a metal powder silo, a linkage belt is tightly fitted onto the four forward turntables, and a forward drive element drives any one of the reverse turntables to rotate.

[0011] In the auxiliary discharge component of the aforementioned metal powder silo, the distances from the four forward turntables to the center of the cross-shaped frame are consistent.

[0012] In the aforementioned improved discharge device for a metal powder silo, the forward drive element and the reverse drive element rotate in opposite directions and have the same rotation efficiency.

[0013] Compared with existing technologies, this improved discharge device distributes the auxiliary discharge function evenly to all sides through a diversion method, while the anti-clogging material only requires one reverse screw rod located between four forward-rotating screw rods.

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1 As shown, the improved discharge device of this metal powder silo includes a cross-shaped frame 1 fixed on the inner wall support of the silo. A reverse turntable 2 is rotatably provided below the center of the cross-shaped frame 1, and four forward turntables 3 are rotatably provided below the four sides of the cross-shaped frame 1. A screw rod 4 is provided below both the forward turntable 3 and the reverse turntable 2. The cross-shaped frame 1 is also provided with a forward drive element for driving the forward turntable 3 to rotate forward and a reverse drive element for driving the reverse turntable 2 of the cross-shaped frame 1 to rotate in the reverse direction. A diversion plate 5 is provided at the bottom of the silo. Four diversion holes 6 are symmetrically opened in the center of the diversion plate 5. The four forward turntables 3 and the four diversion holes 6 are aligned vertically.

[0018] Compared to the original equipment, this application changes the original equipment from four reverse-rotating and one forward-rotating screws to four forward-rotating and one reverse-rotating screws. This is because the forward-rotating screw 4 provides auxiliary discharge function, while the reverse-rotating screw 4 provides anti-blockage function. The purpose of this equipment is still to assist discharge and increase discharge efficiency. Therefore, a diversion plate 5 is set at the bottom of the hopper, and diversion holes 6 are opened in the direction of the diversion plate 5 and the upward forward-rotating screw 4. Then, the four forward-rotating screws 4 will provide auxiliary discharge power to their respective diversion holes 6 with four times the efficiency of the original application. In order to prevent the four diversion holes 6 from being blocked, the middle reverse-rotating screw 4 can return material appropriately.

[0019] Contrary to the original equipment:

[0020] A linkage belt 7 is tightly fitted on each of the four forward turntables, and the forward drive element drives any one of the reverse turntables 2 to rotate.

[0021] The distances from the four forward turntables 3 to the center of the cross-shaped frame 1 are the same.

[0022] The forward drive element and the reverse drive element rotate in opposite directions and have the same rotation efficiency.

[0023] It should be understood that in the claims and description of this utility model, all instances of "comprising..." should be understood as having an open meaning, that is, their meaning is equivalent to "containing at least...", and should not be understood as having a closed meaning, that is, their meaning should not be understood as "containing only...".

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
