Description

Technical Field

[0001] The utility model relates to the technical field of copper powder mixing, in particular to a moisture exhaust type copper powder mixer. Background Art

[0002] When the mixer mixes copper powder, moisture may be generated due to frictional heat. In order to avoid the influence of moisture on the mixing of copper powder, an air outlet is usually provided at the upper end of the mixing barrel (a filter layer is provided in the air outlet to only allow moisture to pass through), and the moisture generated by friction in the mixing barrel can be discharged through this air outlet.

[0003] The mixer used by our company (the reference authorization announcement number is CN 206996415 U, and the name is a static electricity-removing copper powder mixer) has an air outlet at the upper end of the mixing barrel. The air outlet performs circular mixing motion with the mixing barrel. When the air outlet rotates to a vertically downward state, the raw materials in the mixing barrel accumulate above the filter layer (exhaust cannot be performed at this time), which can easily cause the filter layer to be blocked or the raw materials to agglomerate on the filter layer, thereby affecting the discharge of moisture. Therefore, this application provides a moisture-exhaust type copper powder mixer to meet the needs. Utility Model Content

Elastic sealing rings are arranged on both side walls of the inner ring. The outer end surfaces of the two elastic sealing rings are in sliding contact with the corresponding mounting rings. The exhaust pipe is vertically arranged at the highest point of the upper part of the outer ring, and the lower end of the exhaust pipe passes through the outer ring and the inner ring. A weight block is arranged at the lowest point of the bottom of the outer ring.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: Reference Figure 1 The shown moisture exhaust type copper powder mixer includes two Z-shaped rotating shafts 2 rotatably arranged on a frame 1, a driving motor 7 with a reducer and a mixing barrel 3, the two ends of the mixing barrel 3 are respectively installed and connected with the corresponding Z-shaped rotating shafts 2, the driving shaft of the driving motor 7 is fixedly connected with the end of one of the Z-shaped rotating shafts 2, the mixing barrel 3 is provided with an inlet and outlet pipe, and the inlet and outlet pipes are installed with an opening and closing valve, the mixing barrel 3 is provided with an exhaust pipe 5, and the inner cavity of the exhaust pipe 5 is provided with a filter layer 10, characterized in that it also includes a moisture exhaust unit, which is used to ensure that as the mixing barrel 3 performs a circular mixing motion, moisture is always discharged vertically upward from the exhaust pipe 5.

[0021] The moisture exhaust unit allows moisture to be exhausted vertically upward at all times, so that the copper powder accumulated at the bottom of the mixing barrel 3 cannot cover the filter layer 10, thereby preventing the filter layer 10 from being blocked or agglomerated, so that the exhaust can be uninterrupted during the entire rotating mixing process of the mixing barrel 3, thereby improving the moisture exhaust efficiency.

[0022] It should be noted that the filter layer 10 includes a filter screen and a gauze layer arranged in an upper and lower manner, which allows the gas in the mixing barrel 3 to be discharged and the copper powder to be retained.

[0023] As a preferred implementation in this embodiment, Figure 1-3As shown, the mixing barrel 3 includes two receiving barrels 31 arranged opposite to each other and a hollow barrel 32 located between the two receiving barrels 31, the right end of the hollow barrel 32 is connected with the left end of the right receiving barrel 31, a reserved gap is provided between the left end of the hollow barrel 32 and the right end of the left receiving barrel 31, and a mounting ring 33 is provided on both the left end of the hollow barrel 32 and the right end of the left receiving barrel 31;

[0024] The moisture discharge unit includes an outer ring 4 and an inner ring 11 arranged inside the outer ring 4. The outer ring 4 is rotatably connected to two mounting rings 33 through two bearings 9 respectively. The inner ring 11 is located in the reserved gap. Elastic sealing rings 8 are arranged on both side walls of the inner ring 11. The outer end surfaces of the two elastic sealing rings 8 are in sliding contact with the corresponding mounting rings 33. The exhaust pipe 5 is vertically arranged at the highest point of the upper part of the outer ring 4, and the lower end of the exhaust pipe 5 passes through the outer ring 4 and the inner ring 11. A weight block 6 is arranged at the lowest point of the bottom of the outer ring 4.

[0025] When in use, driven by the driving motor 7, the mixing barrel 3 performs a circular rotating mixing motion. At the same time, under the action of the gravity of the weight block 6, the outer ring 4 can drive the inner ring 11 to rotate relative to the containing barrel 31 and the hollow barrel 32, thereby ensuring that the exhaust pipe 5 on the outer ring 4 is always set to exhaust upwards, thereby avoiding the copper powder accumulated at the bottom of the inner cavity of the hollow barrel 3 from covering the filter layer 10 in the exhaust pipe 5, so that the mixing barrel 3 can be exhausted uninterruptedly during the entire rotating mixing process, thereby improving the moisture discharge efficiency.

[0026] It should be noted that, first, a plurality of interception plates 16 (such as Figure 2 and Figure 4 As shown in the figure, the interception plate 16 is arranged on the inner wall of the containing barrel 31 and the hollow barrel 32. The copper powder accumulated inside the mixing barrel 3 can be driven to a height by the interception plate 16 and then dropped to mix, thereby improving the mixing effect. The interception plate 16 is not provided on the inner wall of the inner ring 11; second, the inner wall of the mixing barrel 3 is provided with a guide slope 17 (as shown in the figure) on the left and right sides. Figure 2 As shown), and the bottom ends of the guide slopes 17 are arranged close to the material ports of the inlet and outlet pipes, so as to facilitate the subsequent discharge of the copper powder in the mixing barrel 3 (when discharging, the inlet and outlet pipes are arranged downward. Due to the arrangement of the guide slopes 17, the copper powder in the mixing barrel 3 can be accumulated toward the inlet and outlet pipes, which is conducive to the complete discharge of the copper powder in the mixing barrel 3).

[0027] As a preferred implementation in this embodiment, Figure 3 As shown, a vibrator 15 is provided at the axis center of the upper end of the filter layer 10 .

[0028] The vibrator 15 can shake off the dust that is blown up by the mixing and adheres to the filter layer 10, so as to avoid the filter layer 10 being blocked by the dust, which is conducive to the smooth discharge of moisture.

[0029] As a preferred implementation in this embodiment, Figure 3 As shown, a baffle plate 12 is obliquely arranged below the exhaust pipe 5, the baffle plate 12 is arranged lower on the left and higher on the right, overflow gaps are arranged between the left and right ends of the baffle plate 12 and the inner wall of the exhaust pipe 5, a second inclined plate 14 is arranged above the overflow gap on the left, the second inclined plate 14 is arranged higher on the left and lower on the right, and a first inclined plate 13 is arranged above the overflow gap on the right, the first inclined plate 13 is arranged lower on the left and higher on the right.

[0030] The baffle 12 is set so that the copper powder that is lifted up (moving upward with the moisture) collides with the baffle 12 and moves downward, so that relatively clean moisture passes through the filter layer 10, which can effectively prevent the filter layer 10 from being blocked. The first inclined plate 13 and the second inclined plate 14 are set at the overflow gap. When part of the moisture flows through the overflow gap, it collides with the first inclined plate 13 and the second inclined plate 14, and the copper powder in the moisture is removed by the collision. The inclined direction of the plate 12 is set so that the copper powder falling to the upper end of the baffle 12 can slide down along the inclined surface of the baffle 12 and finally fall into the mixing barrel 3. Even if the copper powder falls to the upper end of the first inclined plate 13 and the second inclined plate 14, it can slide down along the inclined surface of the first inclined plate 13 or the second inclined plate 14 to the inclined surface of the baffle 12 and finally slide into the mixing barrel 3. The setting of the baffle 12, the first inclined plate 13 and the second inclined plate 14 can reduce the possibility of the filter layer 10 being blocked, which is conducive to the discharge of moisture.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
