Technical Field

[0001] The present application relates to the technical field of powder mixing production equipment, and in particular to a mixing device for multi-component powder. Background Art

[0002] Putty powder is a building decoration material primarily used for wall repair and leveling, laying a good foundation for subsequent decoration (such as painting and wallpapering). Putty powder is composed of a variety of powders, such as calcium carbonate, quartz sand, cement, lime, gypsum, and talc.

[0003] The production process of putty powder requires a mixing device to stir and mix the various components according to a prescribed formula before proceeding to bagging and packaging.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a mixing device for multi-component powder. Figure 1 and Figure 2The mixing device includes a mixing tank 2, multiple batching tanks 1, and a feed pipe 3 mounted at the lower end of the batching tank 1. The batching tanks 1 are spaced apart along the circumference of the mixing tank 2. The batching tanks 1 are used to hold powders of different components, which are then fed into the mixing tank 2 through the feed pipe 3 for mixing. The feed pipe 3 can discharge the powder via a spiral feed rod. The feed pipe 3 is connected to the upper end of the mixing tank 2 at one end away from the batching pipeline to feed the powder into the mixing tank 2.

[0032] A mounting base 4 is mounted on the top surface of the mixing tank 2, and a connecting tube 5 is mounted on the mounting base 4. The connecting tube 5 extends into the interior of the mixing tank 2. The upper end of the connecting tube 5 is connected to the discharge portion of the feed pipe 3. The connecting tube 5 can be adjusted on the mounting base 4 to adjust the connecting tube 5 to the optimal position for connection with the feed pipe 3.

[0033] Reference Figure 2 and Figure 3 , an adjustment hole 6 is provided on the mounting seat 4, which extends to the surface of the mounting seat 4 and is connected to the inner cavity of the mixing tank 2. An annular groove 7 is provided on the inner wall of the adjustment hole 6, and an adjustment ring 8 is coaxially fixed to the outer wall of the lower end of the connecting tube 5, and the adjustment ring 8 extends in the annular groove 7. The outer diameter of the connecting tube 5 is smaller than the inner diameter of the adjustment hole 6. There is a certain distance between the outer wall of the adjustment ring 8 and the inner wall of the annular groove 7, and the adjustment ring 8 can be adjusted in the annular groove 7. A positioning member 9 is installed in the annular groove 7. When the adjustment ring 8 is adjusted to a suitable position, the positioning member 9 can be used to position the adjustment ring 8.

[0034] Positioning member 9 includes a contact ring 91 slidably mounted within annular groove 7, allowing vertical movement. The upper end of contact ring 91 abuts against the lower surface of adjustment ring 8, forcing the upper surface of adjustment ring 8 to press against the inner top surface of annular groove 7. Applying a certain force to drive connecting tube 5 downward overcomes the effect of contact ring 91, separating adjustment ring 8 from the inner top surface of annular groove 7, thereby enabling adjustment of the position of adjustment ring 8.

[0035] Reference Figure 2 and Figure 3The bottom of the ring groove 7 is provided with a sliding groove 10 coaxial with the ring groove 7. The abutting ring 91 is slidingly inserted into the sliding groove 10. The sliding groove 10 is provided with elastic members 92, which are springs and are uniformly distributed along the circumference of the sliding groove 10. One end of the elastic member 92 is connected to the lower end of the abutting ring 91, and the other end is connected to the inner bottom of the sliding groove 10. Under the action of the elastic member 92, the adjusting ring 8 can be driven to abut against the inner top of the ring groove 7. The abutting ring 91 abuts against the lower surface of the adjusting ring 8, improving the sealing between the adjusting ring 8 and the ring groove 7. Further, in order to improve the sealing between the adjusting ring 8 and the ring groove 7 and reduce dust flying out, the inner top of the ring groove 7 is bonded with an elastic ring 11, and the adjusting ring 8 abuts against the elastic ring 11.

[0036] In further embodiments, flanges 12 are fixed at the upper end of the connecting cylinder 5 and the discharge position of the feeding pipe 3. When the two flanges 12 abut against each other, the adjusting ring 8 abuts against the inner top of the ring groove 7. The flanges 12 are provided with a plurality of bolt assemblies 13, which connect the two flanges 12 together by bolt-nut cooperation.

[0037] Further, the outer wall of the mounting seat 4 is provided with a dust cover 14, the lower end of which is fixed to the outer wall of the mounting seat 4 by a hoop or the like. The upper end of the dust cover 14 is fixed to the side wall of the connecting cylinder 5 by a hoop. The dust cover 14 wraps the entire mounting seat 4, further reducing the situation of dust flying into the workshop.

[0038] The implementation principle of the mixing device for multi-component powder of the embodiments of the application is as follows: the position of the adjusting ring 8 is adjusted, the connecting cylinder 5 is adjusted to the optimal position for connecting with the feeding pipe 3, then the adjusting ring 8 abuts against the inner top of the ring groove 7, the abutting ring 91 abuts against the lower surface of the adjusting ring 8, the sealing between the mounting seat 4 and the adjusting ring 8 is improved, and under the action of the dust cover 14, the situation of dust running into the workshop is further reduced.

[0039] The above are preferred embodiments of the application, which do not limit the protection scope of the application. Any equivalent changes made according to the structure, shape and principle of the application should be covered by the protection scope of the application.
