Description

Technical Field

[0001] This utility model relates to the field of pigment production technology, and in particular to a mixing device for water-based pigment raw materials. Background Technology

[0002] Water-based pigment pastes are concentrated pigment pastes that use water as a medium to form a uniform and stable mixture of organic or inorganic pigments through the wetting and dispersing action of surfactants. Water-based pigment pastes have a wide range of applications, including coatings, wood varnishes, latex products, papermaking, leather dyeing, and textile printing and dyeing, playing an important role in modern industry.

[0003] With increasing environmental awareness and rising global environmental standards, water-based pigments, as an environmentally friendly, easy-to-adjust, and stable coloring material, are widely used in many fields. However, in the existing water-based pigment mixing process, the raw materials often adhere to the inner wall of the mixing drum, resulting in insufficient mixing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-based pigment raw material mixing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water-based pigment raw material mixing device includes a mixing cylinder and a T-shaped rod. The mixing cylinder is surrounded by an outer shell, forming a sandwich between the mixing cylinder and the outer shell. A motor is fixedly installed on the top of the mixing cylinder, and the motor vertically drives a rotating shaft located inside the mixing cylinder. A set of connecting plates is provided on both sides of the rotating shaft. A vertical plate is fixedly installed on one side of the connecting plate. A slot is opened on the vertical plate, and a strip is vertically inserted into the slot. A threaded hole is opened on the top of the strip, and a scraper is fixedly installed on the outside of the strip. The scraper contacts the inner wall of the mixing cylinder. Three sets of stirring blades are fixedly installed on the rotating shaft.

[0007] Furthermore, in a preferred configuration, the bottom of the T-shaped rod is provided with a threaded post, and the threaded post matches the threaded hole.

[0008] In addition, a preferred structure is that a through groove is provided at one end of the top of the mixing cylinder, and a raw material inlet is installed at the top of the mixing cylinder by screws, with a filter screen installed inside the raw material inlet.

[0009] In addition, a preferred structure is that a discharge valve is provided at the bottom of the mixing cylinder, and the bottom of the mixing cylinder is conical.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A water-based pigment raw material mixing device includes a mixing cylinder 1 and a T-shaped rod 15. A shell 2 is provided outside the mixing cylinder 1, and a sandwich 7 is formed between the mixing cylinder 1 and the shell 2. A motor 4 is fixedly installed on the top of the mixing cylinder 1. The motor 4 vertically drives a rotating shaft 9 located inside the mixing cylinder 1. A set of connecting plates 10 are provided on both sides of the rotating shaft 9. A vertical plate 11 is fixedly installed on one side of the connecting plate 11. A slot 111 is opened on the vertical plate 11. An insert 14 is vertically inserted into the slot 111. A threaded hole 141 is opened on the top of the insert 14. A scraper 12 is fixedly installed on the outside of the insert 14. The scraper 12 contacts the inner wall of the mixing cylinder 1. Three sets of stirring blades 13 are fixedly installed on the rotating shaft 9.

[0023] The bottom of the T-shaped rod 15 is provided with a threaded post 151, and the threaded post 151 matches the threaded hole 141. The threaded post 151 is threaded into the threaded hole 141, which makes it easy to remove the scraper 12 for replacement.

[0024] Meanwhile, a through groove 101 is provided at one end of the top of the mixing cylinder 1. The scraper 12 is taken out from the inside of the mixing cylinder 1 through the through groove 101. A raw material inlet 5 is installed on the top of the mixing cylinder 1 by screws. A filter screen 51 is provided in the raw material inlet 5. Impurities in the raw material are intercepted by the filtering effect of the filter screen 51. Loosen the screws to remove the raw material inlet 5, so as to facilitate the cleaning of the filter screen 51.

[0025] Meanwhile, a discharge valve 6 is provided at the bottom of the mixing cylinder 1. The bottom of the mixing cylinder 1 is cone-shaped, and the raw material is discharged through the discharge valve 6 along the slope of the cone shape.

[0026] Furthermore, an annular heating plate 8 is provided inside the interlayer 7. The annular heating plate 8 heats the water inside the interlayer 7, and the heat is transferred to the mixing cylinder 1 to heat the raw materials inside the mixing cylinder 1, so that the raw materials are mixed more thoroughly.

[0027] Meanwhile, a water inlet 21 is provided on the upper part of one side of the outer shell 2, and a drain valve 22 is provided on the lower part of one side of the outer shell 2, so as to facilitate the injection and discharge of water in the interlayer 7.

[0028] Furthermore, a support frame 3 is provided at the bottom of the mixing cylinder 1, which enhances the stability of the device.

[0029] In this embodiment, an external device is connected to the water inlet 21, allowing external water to enter the interlayer 7. When the water level in the interlayer 7 reaches the required amount, water injection is stopped, and the external device is disconnected from the water inlet 21. The annular heating plate 8 heats the water in the interlayer 7. Then, the prepared water-based pigment raw material is introduced into the mixing drum 1 through the raw material inlet 5. Impurities in the raw material are intercepted by the filter screen 51. Next, the motor 4 is started to drive the rotating shaft 9 to rotate at a constant speed. The hot water in the interlayer 7 heats the raw material through the mixing drum 7, reducing the probability of raw material agglomeration. This ensures more thorough mixing. The rotating shaft 9 rotates at a constant speed, driving the stirring blades 13, vertical plate 11, and scraper 12 to rotate synchronously. The stirring blades 13 then mix the raw materials. During the mixing process, some raw materials will adhere to the inner wall of the mixing cylinder 1. The raw materials adsorbed on the inner wall of the mixing cylinder 1 are scraped off by the rotating scraper 151 and then mixed by the stirring blades 13. After the mixing is completed, the motor 4 is turned off, the rotating shaft 9 stops rotating, and then the external storage device is aligned with the discharge valve 6. The discharge valve 6 is then opened to discharge the mixed water-based pigment paste for centralized collection.

[0030] When the scraper 12 needs to be replaced after a long period of use, simply start the motor 4 to drive the rotating shaft 9 to rotate. Stop rotating the scraper 12 when it is directly below the through groove 101. Align the threaded post 151 at the bottom of the T-shaped rod 15 with the threaded hole 141 and insert it threadedly. Then pull the T-shaped rod 15 to remove the scraper 12. Next, thread the threaded post 151 into the threaded hole 141 of the insert 14 on one side of the new scraper 12. Align the insert 14 with the slot 111 and insert it vertically. Then, the threaded post 151 will leave the threaded hole 141, thus completing the replacement of the scraper 12.

[0031] In this invention, the water-based pigment adsorbed on the inner wall of the mixing cylinder 1 is detached from the inner wall of the mixing cylinder 1 by the scraper 12. The water-based pigment is heated by the hot water in the jacket 7 inside the mixing cylinder 1 and then stirred by the stirring blade 13, so that the water-based pigment is fully stirred and mixed.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
