Description

Technical Field

[0001] This utility model relates to the field of iron oxide production and preparation technology, specifically a bidirectional reverse-rotation iron oxide slurry stirring device. Background Technology

[0002] In the prior art, iron oxide needs to be stirred during the specific production and preparation process. The specific structural design of the existing iron oxide slurry stirring mechanism, for example, the technical solution disclosed in Publication (Announcement) No.: CN104353389A, is "a stirring device for iron oxide pigment".

[0003] This technical solution includes a drive motor and stirring blades. Stirring is mainly achieved by rotating the stirring blades. This technical solution, as well as most existing technical solutions, mostly use a unidirectional stirring device inside the stirring device. However, the stirring quality and efficiency of unidirectional stirring devices are relatively low, and sometimes they cannot meet the stirring requirements of iron oxide slurry.

[0004] Therefore, in order to solve the above problems, it is necessary to develop a bidirectional reverse-rotation iron oxide slurry mixing device with a reasonable structure that can improve the mixing quality and mixing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a bidirectional reverse-rotation iron oxide slurry mixing device; its technical solution is as follows:

[0006] A bidirectional reverse-rotation iron oxide slurry mixing device includes a mixing tank. An upper mixing mechanism is provided at the upper end of the mixing tank. The main shaft of the upper mixing mechanism extends downward into the mixing tank, and inner mixing rods with uniform vertical spacing are installed on the main shaft. A gap is left between the inner mixing rods and the inner wall of the mixing tank.

[0007] The lower end of the mixing tank is provided with a lower stirring mechanism. The main shaft of the lower stirring mechanism extends upward into the mixing tank, and a cylindrical inner mesh cylinder is installed at the shaft end. The inner mesh cylinder extends upward to the upper inner wall of the mixing tank, and the inner stirring rod is located entirely inside the inner mesh cylinder. A number of evenly spaced outer stirring rods are installed on the outer wall of the inner mesh cylinder, and the outer stirring rods extend laterally to the inner wall of the mixing tank.

[0008] The area inside the inner mesh cylinder is designated as the inner stirring area. When the upper stirring mechanism is started, the inner stirring rod stirs this area. The area between the inner mesh cylinder and the inner wall of the mixing tank is designated as the outer stirring area. When the lower stirring mechanism is started, the outer stirring rod stirs this area.

[0009] Furthermore, the mixing tank is provided with a feed pipe at the upper end and a discharge pipe at the lower end, and both the feed pipe and the discharge pipe are equipped with solenoid valves.

[0010] Furthermore, an annular groove corresponding to the position of the inner mesh cylinder is provided at the lower end face of the upper bottom plate of the mixing tank; the inner mesh cylinder extends upward into the annular groove.

[0011] Furthermore, a transverse groove is provided at the upper end of the annular groove, so that the overall vertical cross-section of the annular groove and the transverse groove is "T" shaped; and a transverse annular plate is correspondingly provided at the upper end of the inner mesh cylinder, and the transverse annular plate is correspondingly embedded in the transverse groove.

[0012] Furthermore, ball grooves are provided on both sides of the transverse groove, and support balls are placed in the ball grooves. The support balls support the transverse ring plate upwards, thereby stabilizing the upper end of the inner mesh cylinder.

[0013] Furthermore, the inner stirring rods on the main shaft of the upper stirring mechanism are arranged in five groups with evenly spaced vertical spacing, and each group has six evenly spaced stirring rods; the outer stirring rods on the inner mesh cylinder of the lower stirring mechanism are arranged in five groups with evenly spaced vertical spacing, and each group has six evenly spaced stirring rods.

[0014] Beneficial effects: This utility model has the following beneficial effects:

[0015] 1) The technical solution of this device is mainly to set up two mixing zones inside the mixing device. Specifically, the inner area is set as the inner mixing zone by setting an inner mesh cylinder, and the outer area is set as the outer mixing zone. Different technical means are used for mixing in the two mixing zones. The inner mixing zone is mixed by an upper mixing mechanism and an inner mixing rod, while the outer mixing zone is mixed by a lower mixing mechanism and an outer mixing rod. With this setting, the upper and lower mixing mechanisms can be set to rotate in opposite directions. The slurry will not simply rotate in one direction, but will rotate in two opposite directions, which can effectively increase the mixing quality and mixing efficiency of the slurry.

[0016] 2) In this device, the lower stirring mechanism is installed with the inner screen cylinder via the main shaft. If the inner screen cylinder is supported only by the main shaft of the lower stirring mechanism, it will be somewhat unstable. Therefore, this device is equipped with an annular groove. First, the upper end of the inner screen cylinder extends into the annular groove. Then, a transverse groove is set, and the transverse sliding plate of the inner screen cylinder extends into the transverse groove. Then, a ball groove and support balls are set in the transverse groove. The support balls can support the transverse annular plate upwards, thereby supporting the entire inner screen cylinder. The overall installation of the inner screen cylinder is very stable and reliable. The upper end position is very stable and can rotate smoothly with the lower stirring mechanism. The structure is stable and reliable and easy to use.

[0017] 3) The internal mixing zone of this device is mainly equipped with an internal mixing rod installed through the main shaft, which is simple and reasonable in structure; while the external mixing zone is equipped with an external mixing rod installed through an internal mesh cylinder. The reasonable setting of the number of each mixing rod can effectively increase the mixing efficiency and quality; in addition, the internal mesh cylinder itself is designed as a mesh cylinder structure, which will not hinder the mixing of slurry, and the structure is reasonable.

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a bidirectional reverse-rotation iron oxide slurry mixing device includes a mixing tank 1. An upper mixing mechanism 2 is provided at the upper end of the mixing tank 1. The main shaft of the upper mixing mechanism 2 extends downward into the mixing tank 1, and inner mixing rods 3 with uniform vertical spacing are installed on the main shaft. A gap is left between the inner mixing rods 3 and the inner wall of the mixing tank 1.

[0023] A lower stirring mechanism 4 is provided at the lower end of the mixing tank 1. The main shaft of the lower stirring mechanism 4 extends upward into the mixing tank 1, and a cylindrical inner mesh cylinder 5 is installed at the shaft end. The inner mesh cylinder 5 extends upward to the upper inner wall of the mixing tank 1, while the inner stirring rod 3 is located entirely inside the inner mesh cylinder 5. A number of evenly spaced outer stirring rods 6 are correspondingly installed on the outer wall of the inner mesh cylinder 5, and the outer stirring rods 6 extend laterally to the inner wall of the mixing tank 1.

[0024] The area inside the inner mesh cylinder 5 is designated as the inner stirring area 7. When the upper stirring mechanism 2 is started, the inner stirring rod 3 stirs this area. The area between the inner mesh cylinder 5 and the inner wall of the mixing box 1 is designated as the outer stirring area 8. When the lower stirring mechanism 4 is started, the outer stirring rod 6 stirs this area.

[0025] The main technical solution of this device is to set up two mixing zones inside the mixing device. Specifically, the inner area is set as the inner mixing zone by setting an inner mesh cylinder, and the outer area is set as the outer mixing zone. Different technical means are used for mixing in the two mixing zones. The inner mixing zone is achieved by the upper mixing mechanism and the inner mixing rod, while the outer mixing zone is achieved by the lower mixing mechanism and the outer mixing rod. With this setting, the upper and lower mixing mechanisms can be set to rotate in opposite directions. The slurry will not simply rotate in one direction, but will rotate in two opposing directions, which can effectively increase the mixing quality and mixing efficiency of the slurry.

[0026] The upper end of the mixing tank 1 is provided with a feed pipe 9, and the lower end of the mixing tank 1 is provided with a discharge pipe 10. Solenoid valves 11 are installed on both the feed pipe 9 and the discharge pipe 10.

[0027] An annular groove 12 corresponding to the position of the inner mesh cylinder 5 is provided at the lower end face of the upper bottom plate of the mixing tank 1; the inner mesh cylinder 5 extends upward into the annular groove 12.

[0028] The upper end of the annular groove 12 is also provided with a transverse groove 13, so that the overall vertical cross section of the annular groove 12 and the transverse groove 13 is "T" shaped; and the upper end of the inner mesh cylinder 5 is provided with a transverse ring plate 14, which is correspondingly embedded in the transverse groove 13.

[0029] Both sides of the transverse groove 13 are provided with ball grooves 15, and support balls 16 are placed in the ball grooves 15. The support balls 16 support the transverse ring plate 14 upwards, thereby making the upper end of the inner mesh cylinder 5 stable.

[0030] In this device, the lower stirring mechanism is mounted on the inner screen cylinder via a main shaft. If the inner screen cylinder were supported solely by the main shaft of the lower stirring mechanism, it would be unstable. Therefore, this device incorporates an annular groove. First, the upper end of the inner screen cylinder extends into this annular groove. Then, a transverse groove is provided, into which the transverse sliding plate of the inner screen cylinder extends. Next, a ball bearing groove and supporting balls are installed in the transverse groove. The supporting balls can support the transverse annular plate upwards, thereby supporting the entire inner screen cylinder. The overall installation of the inner screen cylinder is very stable and reliable, with a stable upper end position, and it can rotate smoothly with the lower stirring mechanism. The structure is stable, reliable, and easy to use.

[0031] The inner stirring rods 3 on the main shaft of the upper stirring mechanism 2 are arranged in five groups with evenly spaced vertical spacing, and each group has six evenly spaced stirring rods; the outer stirring rods 6 on the inner mesh cylinder 5 of the lower stirring mechanism 4 are arranged in five groups with evenly spaced vertical spacing, and each group has six evenly spaced stirring rods.

[0032] The internal mixing zone of this device is mainly achieved by installing the internal mixing rod through the main shaft, which is simple and reasonable in structure. The external mixing zone is achieved by installing the external mixing rod through the internal mesh cylinder. The reasonable setting of the number of each mixing rod can effectively increase the mixing efficiency and quality. In addition, the internal mesh cylinder itself is designed as a mesh cylinder structure, which will not hinder the mixing of the slurry, and the structure is reasonable.

[0033] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
