Description

Technical Field

[0001] The utility model belongs to the field of horizontal mixer manufacturing, and more specifically relates to a horizontal three-dimensional stirring device. Background Art

[0002] Horizontal industrial mixers are widely used in the fields of concrete mixing, cement mixing, etc. In order to produce high-quality products economically and efficiently, the manufacturers of mixers continuously optimize and improve the structure of the mixers, so that the mixers can be further improved in terms of mixing uniformity, mixing efficiency and other performance. For example, the authorization announcement number is CN201067678Y, and the publication date is 2015.09.30, which discloses a high-efficiency horizontal mixer and commercial mortar mixing equipment, including a horizontal cylinder, a stirring shaft that passes through the cylinder axially and can be rotatably supported, and a plurality of stirring units arranged on the stirring shaft, each of which includes an upright stirring arm connected to the stirring shaft, a first stirring blade arranged at the end of the stirring arm, and a second stirring blade vertically arranged in the middle of the stirring arm and extending in the direction away from the first stirring blade. This horizontal mixer produces a three-dimensional stirring effect through the first stirring blade and the second stirring blade, so that the materials can be evenly mixed in a short time, and the performance of the mixer is continuously improved. The stirring blades used are spiral in shape as a whole. The design spiral parameters of the spiral stirring, including the spiral outer diameter, spiral lead, spiral angle, number of spiral heads and wear-resistant parameters, are key parameters affecting the performance of the entire mill. When there are multiple spiral layers, the spiral one-piece molded product needs to directly weld the wear-resistant alloy cast blades to the main shaft after molding. After wear, it needs to be replaced as a whole or repaired at a high cost. In recent years, mill manufacturers in various countries in the world have been developing split spiral agitator structures to facilitate the installation and disassembly of spiral blades and replace interchangeable spiral stirring blades. The split structure must not only be easy to connect and fix, but also ensure that the process parameters of the spiral agitator remain consistent after connection. This is difficult and the installation accuracy is difficult to guarantee. Moreover, the circular circumference of the stirring shaft makes the vertical installation of the stirring arm and the stability effect after installation need to be improved.

[0003] In response to the above problems, after searching, the patent document with Chinese patent publication number CN 71889978 A and publication date 2022.02.25 discloses a method for making a spiral stirring blade for a large vertical mill, which can effectively solve the problem that the existing technology is inconvenient to operate and cannot guarantee the process parameters of the spiral stirrer. The technical solution is to obtain the operating parameters by simulating the flow field state of the spiral blade in two-dimensional and three-dimensional computers, and to optimize the blade shape and the blanking size of the blade carriage by combining test data and theoretical calculation results. The preliminary blanking diagram is obtained by lofting and unfolding, and then the 3D mold diagram and sample box diagram are simulated and reversed. After the matching mold is made, the mold is used for cold pressing, and reasonable deformation compensation is left after the pallet is unloaded. The spiral stirring blade blanking diagram is further improved. The invention improves production efficiency while strictly controlling quality, reaches high-precision standards, and improves the first-time qualified rate of products. The invention has a complex process, and the molding requires multiple computer simulation compensations. A lot of redundant designs are also required in the cylinder, and the application scenarios are limited. Utility Model Content

[0006] 2. Technical solution

[0007] In order to solve the above problems, the utility model adopts the following technical solutions:

[0008] A horizontal three-dimensional stirring device comprises a stirring shaft which is laterally rotatably fixed to a horizontal cylinder and a spiral stirring blade which is fixedly connected to the stirring shaft via a stirring arm.

[0013] A further technical solution is that the curvature of the arc line is adapted to the upper projection curvature of the spiral panel and is consistent with the spiral outer diameter in the spiral parameters; the clamping mechanism includes a support and a flat plate, and the two ends of the flat plate are overlapped with the support and the shaft neck respectively, and then fixedly connected to the slide groove by fixing parts. The fixing parts can be detachable connecting parts such as screw connections and clip connections, which are convenient for disassembly, transfer and adjustment of position.

[0014] A further technical solution is that the slope platform 2, the square platform and the slope platform 1 are provided with baffle rods, screw holes and / or guide rods that are compatible with the guide holes and / or fixing holes vertically penetrated on the end plate 1 and the end plate 2, so as to facilitate stability during welding and ensure the consistency of the welded products; when welding, the end plate 1 of a spiral panel and the end plate 2 of another spiral panel can be laid flat on the welding platform and then welded and fixed, which is simple to operate and does not require computer simulation compensation, with low welding cost and high precision; pads are also provided between the support platform and the flat plate to adjust the balance of the corresponding two ends of the flat plate according to the diameter of the shaft neck.

[0015] A further welding tool also includes a pressing plate, which presses the end plate 1 of one spiral panel and the end plate 2 of another spiral panel onto the square table to avoid displacement of the spiral panels during welding and affect the welding quality.

[0016] For a further welding tool, a slot is reserved at the end of the pressure plate to facilitate cooperation with the fixing hole to maintain stability during welding. The bottom of the V-shaped groove and the support platform both extend downward with a bottom convex, and are slidably connected to the slide groove through the bottom convex, which is convenient for sliding in the groove and saves effort in operation.

[0077] Step 3: First, weld the gaps of the weld seams 40 on the front and rear sides of the pressing plate 15, then remove the pressing plate 15, and then weld the gaps left after the pressing plate 15 is removed. After the two spiral panels 201 are welded together along the gaps of the weld seams 40, the gaps of the weld seams 40 reserved in the middle form the weld seams 40.

[0078] Step 4: After removing the bolts fixing the plates, a spiral stirring blade 20 is generated by welding two spiral panels 201 connected together.

[0079] Step 5: Repeat the above steps to weld multiple pairs of spiral stirring blades 20 connected by welding of spiral panels 201.

[0080] In the processing method of the stirring shaft 10 in the horizontal three-dimensional stirring device of this embodiment, the bottom of the V-groove 21 and the support 31 of the stirring shaft processing tooling both extend downward to form bottom convexities, namely bottom convexity 1 213 and bottom convexity 2 311, and are respectively slidably connected to the parallel chute 11 through bottom convexity 1 213 and bottom convexity 2 311, and slide in the groove to save labor. The opening angle of the V-groove 212 is preferably 90°, which can be applied to the processing of stirring shafts 10 of various specifications. The processing steps are:

[0081] S1: After the journals 101 at both ends of the stirring shaft 10 to be processed are overlapped on the two clamping tables 2 respectively, the journals 101 are pressed in the two clamping tables 2 by the clamping mechanism 3, and the shaft body of the stirring shaft 10 to be processed is cut by a cutting machine tool to form a square plane 102;

[0082] S2: Flip the entire shaft and process the other symmetrical side. After the other side is processed, flip it 60° and process the third side. This process continues until the following is achieved: Figure 2 , 3 As shown, the stirring shaft 10 has a hexagonal cross section. Fig.10 As shown, the calibration folding ruler 5 with an opening angle a=120° can be placed on the operating platform 1, with the ruler back close to the square processing surface 102. If there is a gap between the ruler back and the processing surface 102, it means that the precision is insufficient, and the processing surface 102 can be re-cut by flipping the shaft body until there is no gap. The stirring shaft to be processed is stably clamped by the coordinated cooperation of the V-groove 21, the support 31 and the flat plate 32, and the entire tooling is stably fixed on the operating platform 1 by the cooperation of the T-groove and the T-bolt, and then the shaft body is smoothly cut by the machine tool, thereby improving the processing precision of the square plane 102.

Without departing from the design concept of the present utility model, various modifications and improvements made to the technical solutions of the present utility model by engineers and technicians in this field should all fall within the protection scope of the present utility model.
