Description

Technical Field

[0001] The utility model relates to the technical field of pigment mixing, in particular to a uniform mixing device with pigment liquid level variation. Background Art

[0002] In the pigment production process, in order to obtain the pigment of the target color, multiple raw materials need to be added together in a predetermined proportion and mixed thoroughly.

[0003] Some pigments have a high viscosity and poor fluidity during mixing, which brings difficulties to the mixing device and easily leads to uneven mixing, resulting in color difference of the pigment. In addition, the blade position height on the stirring rod of the mixing device is usually fixed. When the liquid level is high, the stirring blade is difficult to drive the pigment above to mix evenly, which is inefficient.

[0004] In order to achieve uniform mixing of pigments, in the prior art, a utility model patent with application number 2020232812371 discloses a pigment stirring device for improving the uniformity of pigment mixing. The stirring efficiency is improved by moving an inner frame. The structure is relatively complex, and the movement of the inner frame consumes a lot of energy. The stability is also adversely affected, and improvement is needed. Utility Model Content

[0016] Combine the following Figure 1-2 The technical solution of the utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The uniform mixing device for pigment level change shown in the figure comprises: a stirring barrel 1, a stirring rod 13, a feeding hopper 7, a suction cylinder 10 and a piston 4. The stirring rod 13 is vertically arranged in the stirring barrel 1. In this embodiment, a second cover plate 2 is arranged on the top of the stirring barrel 1. The second cover plate 2 is fixed to the top of the stirring barrel 1 by screws, and the structure is stable. A motor 3 for driving the stirring rod 13 to rotate is arranged on the second cover plate 2, and the stirring rod 13 is driven to rotate to achieve the mixing of the raw materials of the pigment in the stirring barrel 1.

[0018] A first transfer tube 11 extending upward is provided at a lower portion of one side of the mixing barrel 1 , the suction cylinder 10 is vertically arranged at the top of the first transfer tube 11 , and a first cover plate 6 is provided at the top of the suction cylinder 10 to seal the top of the suction cylinder 10 .

[0019] The piston 4 is arranged in the suction cylinder 10, and a lifting drive mechanism 5 connected to the piston 4 is arranged on the first cover plate 6. In this embodiment, the lifting drive mechanism 5 adopts a cylinder or a hydraulic cylinder, and a solenoid valve can be used for telescopic control to realize the up and down movement of the piston 4. Figure 2 As shown, during the up and down movement of the piston 4, the raw materials in the mixing barrel 1 are pumped in and out, and the liquid level in the mixing barrel 1 is changed, which is beneficial for the mixing rod 13 to fully mix the raw materials and ensure uniformity.

[0020] When the liquid level is low, the running resistance of the stirring rod 13 is small and the stirring speed is fast. When the liquid level is high, the running resistance of the stirring rod 13 is large and the stirring speed is full, thereby realizing automatic variable speed stirring. The raw materials can be further mixed in the process of switching back and forth between the suction cylinder 10 and the stirring barrel 1, and the mixing effect can be further promoted, the mixing efficiency can be improved, and the structure is simple and the operation and maintenance cost is low.

A first valve 9 is provided in series on the second transfer pipe 8. Figure 1 As shown, after the piston 4 moves up to above the interface between the second transfer tube 8 and the suction cylinder 10, the first valve 9 is opened, and the raw materials in the hopper 7 can be introduced into the suction cylinder 10 and flow into the mixing barrel 1 along the first transfer tube 11, thereby realizing rapid feeding.

[0022] like Figure 1 As shown, a second valve 12 is provided at the bottom of the mixing barrel 1. After the pigments are mixed evenly, the second valve 12 is opened to release the finished product, which is convenient for subsequent packaging.
