Abstract
Description
Technical Field
[0001] This utility model relates to the field of agitator technology, and in particular to a fan-blade agitator. Background Technology
[0002] In industrial production, agitators are key equipment for achieving processes such as material mixing, reaction, and mass transfer.
[0003] Most of the mixers commonly found on the market use a single blade structure, which has the following shortcomings: First, the connection between the blade and the mixing shaft is mostly fixed by welding. When the blade is worn or needs to be replaced to adapt to different materials, disassembly and assembly are difficult and maintenance costs are high.
[0004] Secondly, traditional blades primarily act on materials through axial flow, resulting in insufficient radial flow intensity. This leads to uneven mixing of materials in the radial direction and low discharge volume, making it difficult to meet the requirements of efficient mixing and rapid discharge. Therefore, we proposed a fan-shaped agitator to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fan-shaped agitator.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A fan-shaped agitator includes a stirring shaft with four fixed sleeves. Two mounting plates are fixedly installed at equal intervals on the outer side of the fixed sleeves. The same upper plate frame main blade is installed on the two upper mounting plates along the axial direction via a detachable structure. The upper plate frame main blade has a folded edge groove on the side away from the stirring shaft. The same lower plate frame main blade is installed on the two lower mounting plates along the axial direction via a detachable structure. The lower plate frame main blade has a folded edge groove on the side away from the stirring shaft. Sub-plate frame blades are installed on the sides of the two upper plate frame main blades and the sides of the two lower plate frame main blades that are away from each other.
[0008] Preferably, the mounting plate has a mounting hole one, and the upper plate frame main blade and the lower plate frame main blade each have two mounting holes two, and a mounting mechanism is provided between the mounting hole one and the corresponding mounting hole two.
[0009] Preferably, the mounting mechanism includes a fixing bolt and a fixing nut, wherein the fixing bolt passes through the corresponding mounting hole one and mounting hole two and is threaded with a fixing nut.
[0010] Preferably, both the upper plate frame type main blade and the lower plate frame type main blade are fixedly installed with multiple adjusting screws, and a locking mechanism is provided between the adjusting screws and the corresponding secondary plate frame type blades.
[0011] Preferably, the locking mechanism includes a fixing hole and a locking nut. The sub-plate frame blade has multiple fixing holes, and two locking nuts are threaded onto the adjusting screw. The sub-plate frame blade is located between the corresponding two locking nuts.
[0012] Preferably, the cross-section of the sub-plate frame blade is set to trapezoidal.
[0013] The beneficial effects of this utility model are:
[0014] 1. The main blades are detachably connected to the mounting plate by fixing bolts and fixing nuts. When the main blades are worn or need to be replaced, there is no need to disassemble the stirring shaft. The main blades can be removed simply by loosening the fixing nuts, which reduces maintenance costs and operation difficulty.
[0015] 2. The folded groove one and folded groove two of the upper and lower plate frame main blades can enhance the stirring power. Combined with the secondary plate frame blades with a trapezoidal cross section, they can effectively divide and guide the material flow, greatly improve the radial flow intensity of the material, and solve the problem of uneven radial mixing in traditional agitators.
[0016] 3. Enhanced radial flow can increase the discharge volume of the stirring system and improve material handling efficiency, making it suitable for chemical reactions, solution mixing and other conditions that require rapid discharge. Attached Figure Description

Detailed Implementation
[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses a fan-type agitator.
[0024] Reference Figure 1-4 A fan-shaped agitator includes a stirring shaft 101, which is cylindrical in shape. Four fixing sleeves 102 are fixedly fitted onto its outer wall. The four fixing sleeves 102 are evenly spaced along the axial direction of the stirring shaft 101 and are fixed to the stirring shaft 101 by welding to ensure no relative rotation during stirring. Two mounting plates 103 are evenly spaced along the circumference of the outer wall of each fixing sleeve 102. Each mounting plate 103 is a rectangular metal plate, with one side welded to the outer wall of the fixing sleeve 102 and the other side extending away from the stirring shaft 101. Corresponding to the upper two fixing sleeves 102 distributed along the axial direction of the stirring shaft 101... The two mounting plates 103 are detachably mounted with the same upper plate frame main blade 104. The upper plate frame main blade 104 is a rectangular plate frame structure. Its edge away from the stirring shaft 101 is bent towards the stirring direction to form a folded edge groove 105, which is used to enhance the stirring power. On the two lower fixing sleeves 102 distributed along the stirring shaft 101, the corresponding two mounting plates 103 are detachably mounted with the same lower plate frame main blade 106. The lower plate frame main blade 106 is symmetrical to the upper plate frame main blade 104. Its edge away from the stirring shaft 101 is bent towards the stirring direction to form a folded edge groove 107, which is used to enhance the stirring power.
[0025] In this embodiment, a secondary plate frame blade 108 is installed on the side of the two upper plate frame main blades 104 that are far apart from each other and on the side of the two lower plate frame main blades 106 that are far apart from each other. The cross-section of the secondary plate frame blade 108 is set as trapezoidal.
[0026] In this embodiment, the detachable structure includes mounting hole 1 201, mounting hole 202, and mounting mechanism. The mounting plate 103 has two mounting holes 1 201. The upper plate frame main blade 104 and the lower plate frame main blade 106 both have mounting holes 2 202 corresponding to mounting holes 1 201. The mounting mechanism passes through mounting holes 1 201 and mounting holes 2 202 to fix the main blade to the mounting plate 103. The mounting mechanism includes a fixing bolt 203 and a fixing nut 204. The shank of the fixing bolt 203 passes through the corresponding mounting holes 1 201 and 2 202 in sequence, and the fixing nut 204 is threaded at the end of the shank of the fixing bolt 203. By tightening the fixing nut 204, the main blade can be tightly fixed to the mounting plate 103. When disassembling, the fixing nut 204 can be loosened to remove the main blade.
[0027] In this embodiment, multiple adjusting screws 302 are fixedly installed on the outer walls of both the upper plate frame main blade 104 and the lower plate frame main blade 106. The adjusting screws 302 are evenly distributed along the height direction of the main blade, and the axis of the adjusting screws 302 is perpendicular to the side wall of the main blade. A locking mechanism is provided between the adjusting screws 302 and the corresponding secondary plate frame blades 108. The locking mechanism includes a fixing hole 301 and a locking nut 303. The two ends of the secondary plate frame blades 108 are provided with fixing holes 301 corresponding to the adjusting screws 302. The adjusting screws 302 pass through the fixing holes 301, and a locking nut 303 is threaded on each side of the secondary plate frame blades 108 on the adjusting screws 302. By tightening the locking nuts 303 on both sides, the secondary plate frame blades 108 can be fixed on the adjusting screws 302. By loosening the locking nuts 303, the position of the secondary plate frame blades 108 can be adjusted along the axis of the adjusting screws 302 to adapt to the stirring requirements of different materials.
[0028] The working principle of this utility model is as follows: First, align the upper plate frame main blade 104 with the mounting plate 103 of the two upper fixing sleeves 102, so that the mounting hole 1 201 is aligned with the mounting hole 202, insert the fixing bolt 203 and tighten the fixing nut 204; the lower plate frame main blade 106 is installed on the mounting plate 103 of the two lower fixing sleeves 102 in the same way, which can achieve the purpose of fixing and installing the upper plate frame blade and the lower plate frame blade.
[0029] A locking nut 303 is threaded onto the adjusting screw 302. Then, the fixing hole 301 of the secondary plate frame blade 108 is fitted into the adjusting screw 302. The distance between the secondary plate frame blade and the main blade is adjusted according to the material mixing requirements. Then, a locking nut 303 is threaded onto the blade. The two corresponding locking nuts 303 are rotated toward the secondary plate frame blade. The locking nuts 303 can be used to fix and adjust the secondary plate frame blade 108.
[0030] The agitator is installed inside the mixing tank. The drive unit is started to rotate the agitator shaft 101. The upper and lower plate-frame main blades 106 provide the main stirring power through the first folded groove 105 and the second folded groove 107 during rotation, which promotes the axial and radial flow of the material. The secondary plate-frame blades 108 rotate with the main blades, further dividing the material flow and enhancing the radial flow intensity of the material, so that the material is fully mixed in the radial direction, while increasing the discharge volume, thus achieving efficient stirring and discharge.
[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
