Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, specifically to a mixing device. Background Technology

[0002] In metallurgical and chemical production, mixing tanks operate by transmitting power from the stirring motor to the stirring shaft via a transmission device, which in turn drives the agitator to mix materials within the tank. During this process, the torque generated by the material resistance acting on the agitator, as well as the weight of the agitator, shaft, and material, are transmitted to the tank body through the cable tray and support legs. The tank body must withstand the combined effects of vertical force, horizontal force, torque, and bending moment. However, while concrete tanks have high compressive strength, they are prone to fracture under tensile stress due to their lack of ductility. Therefore, if localized areas of a concrete tank are subjected to alternating loads for extended periods, the surface concrete material is easily damaged and may detach, reducing the tank's service life.

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following is a reference to the appendix. Figures 1 to 7 The stirring device 100 of this utility model embodiment is described in detail below.

[0032] The stirring device 100 of this embodiment includes a tank 1, support legs 2, and a bridge 3. The tank 1 is in a first direction (e.g., Figure 1 Support surfaces 11 are provided at both ends of the support (in the left and right directions). The support leg 2 is mounted on the support surface 11 and includes a first wing plate 21, a second wing plate 22, and a web plate 23. Each of the first wing plate 21 and the second wing plate 22 is provided in the second direction (e.g., in the left and right directions). Figure 2 and Figure 4 The dimension in the front-to-back direction is larger than the dimension in the first direction, and each of the first wing plate 21 and the second wing plate 22 is along a third direction (e.g., in the front-to-back direction) is larger than the dimension in the first direction. Figure 1 The projection of the upper and lower directions of the support surface 11 onto the support surface 11 covers both ends of the support surface 11 in the second direction. The first wing plate 21 is connected to the support surface 11, the web plate 23 is disposed on the first wing plate 21, and the second wing plate 22 is disposed on the web plate 23. The third direction is orthogonal to the second direction and the first direction. The cable tray 3 is disposed on the second wing plate 22.

[0033] The mixing device 100 also includes a stirrer 5, which is mounted on the bridge 3.

[0034] In the usage state, the stirring device 100 of this utility model has the same third direction as the up and down direction, and the support surface 11 is located on the upper side of the tank 1. The support surface 11 is part of the upper surface of the tank 1.

[0035] In this embodiment of the stirring device 100, the support leg 2 connects the connecting groove 1 and the bridge frame 3. The first wing plate 21 abuts against the groove 1, and the second wing plate 22 abuts against the bridge frame 3. Each of the first wing plate 21 and the second wing plate 22 has a larger dimension in the second direction than in the first direction. Therefore, both the first wing plate 21 and the second wing plate 22 are elongated, for example... Figure 4 The rectangle shown in the figure has each of the first wing plate 21 and the second wing plate 22 projecting onto the support surface 11 along the third direction, covering both ends of the support surface 11 in the second direction. That is, the lengths of the first wing plate 21 and the second wing plate 22 both cover both ends of the support surface 11 in the second direction. Through the connection between the first wing plate 21 and the support surface 11, and the connection between the second wing plate 22 and the cable tray 3, compared with the use of columnar legs to connect the tank 1 and the cable tray 3 in related technologies, the contact area between the leg 2 and the tank 1 is increased, and the contact area between the leg 2 and the cable tray 3 is increased. This increases the stability of the connection between the leg 2 and the tank 1, and the leg 2 and the cable tray 3, thereby reducing the local pressure on the upper surface of the tank 1 caused by the vertical load caused by stirring, and thus increasing the service life of the tank 1.

[0036] Therefore, the stirring device 100 of this utility model, by optimizing the structure and size of the support leg 2, increases the contact area between the support leg 2 and the tank body 1, and between the support leg 2 and the bridge frame 3, thereby increasing the stability of the connection between the support leg 2 and the tank body 1, and between the support leg 2 and the bridge frame 3, thereby reducing the local pressure on the upper surface of the tank body 1 caused by the vertical load, improving the service life of the tank body 1, reducing maintenance requirements, and improving production efficiency and safety.

[0037] In some embodiments, the groove 1 includes a body 12 and a boss 13, the boss 13 protruding from the outer surface of the body 12, the boss 13 having a supporting plane, at least a portion of the supporting plane forming a part of a supporting surface 11. Figure 1 , Figure 3 and Figure 4 As shown, the boss 13 is located on the upper side of the groove 1. The body 12 has bosses 13 at both ends in the first direction. The upper surface of the boss 13 is the supporting plane of the boss 13.

[0038] A boss 13 protruding from the body 12 is provided at the support surface 11. On the one hand, it enhances the structural strength of the tank 1 at the support surface 11, that is, it increases the structural strength at the connection between the tank 1 and the support leg 2, thereby improving the service life of the tank 1. On the other hand, the boss 13 can expand the size of the support surface 11 and increase the area of ​​the support surface 11, thereby increasing the contact area between the tank 1 and the first wing plate 21 (support leg 2), increasing the stability of the connection between the support leg 2 and the tank 1, and further reducing the local pressure on the upper surface of the tank 1 caused by the vertical load caused by stirring, further improving the service life of the tank 1.

[0039] Specifically, the body 12 and the boss 13 are formed by casting reinforced concrete, so the boss 13 and the body 12 are formed as one piece.

[0040] In some embodiments, the stirring device 100 further includes a fastening nut (not shown) and a fastening bolt 4, and the tank 1 further includes a reinforcing plate 14. One end (lower end) of the reinforcing plate 14 and the fastening bolt 4 are embedded in the tank 1. The reinforcing plate 14 forms at least a portion of the support surface 11 on one side (upper side) in its thickness direction. The other end of the fastening bolt 4 passes through the reinforcing plate 14 and the first wing plate 21. The fastening nut is installed on the other end (upper end) of the fastening bolt 4 to connect the reinforcing plate 14 and the first wing plate 21.

[0041] The reinforcing plate 14 and fastening bolts 4 are pre-embedded in the tank body 1 and connected to the first wing plate 21, which facilitates the connection between the first wing plate 21 and the tank body 1, simplifies the construction process, enhances the reliability of the connection between the tank body 1 and the support leg 2, and the reinforcing plate 14 can evenly transfer the relatively concentrated load transmitted by the support leg 2 to the tank body 1, reduce stress concentration, and help to further improve the service life of the tank body 1.

[0042] Specifically, when pouring concrete for the body 12 and the boss 13, reinforcing plates 14 and fastening bolts 4 are pre-embedded.

[0043] Specifically, multiple fastening bolts 4 are pre-embedded at both ends of the support surface 11 in the second direction. Each fastening bolt 4 is fitted with a fastening nut. Correspondingly, the first wing plate 21 has a fourth connecting hole 211 corresponding to the fastening bolt 4. When installing the support leg 2 and the trough 1, the fourth connecting hole 211 of the first wing plate 21 is aligned with the fastening bolt 4, so that the upper end of the fastening bolt 4 passes through the fourth connecting hole 211. Then, the fastening nut is fitted onto the fastening bolt 4 to connect the first wing plate 21 and the reinforcing plate 14, thereby fixing the first wing plate 21 and the trough 1. The multiple fastening bolts 4 connecting the reinforcing plate 14 and the first wing plate 21 can strengthen the connection strength and stability between the trough 1 and the support leg 2.

[0044] like Figure 4 In the embodiment shown, four fastening bolts 4 are pre-embedded at both ends of the support surface 11 in the second direction.

[0045] The reinforcing plate 14 can be made of steel plate or stainless steel plate.

[0046] Furthermore, the first wing plate 21 and the reinforcing plate 14 are connected by welding. The welding and fixing of the first wing plate 21 and the reinforcing plate 14 further increases the connection strength between the first wing plate 21 and the reinforcing plate 14, so that there is a larger contact area between the support leg 2 and the tank body 1, thereby further reducing the local pressure on the upper surface of the tank body 1, further reducing the stress on the upper surface of the tank body 1, and helping to further extend the service life of the tank body 1.

[0047] The lengths (i.e., dimensions in the second direction) of the first wing plate 21 and the second wing plate 22 can be greater than, equal to, or less than the length of the support surface 11, provided that the projection of each of the first wing plate 21 and the second wing plate 22 onto the support surface 11 in the third direction covers at least a portion of both ends of the support surface 11 in the second direction. In this embodiment, the reinforcing plate 14 forms the support surface 11, that is, the upper side of the reinforcing plate 14 is the support surface 11, the lengths of the first wing plate 21 and the second wing plate 22 are equal to the length of the support surface 11, and the first wing plate 21 completely covers both ends of the support surface 11 in the second direction.

[0048] The web plate 23 is perpendicular to the second wing plate 22 and the first wing plate 21, and the web plate 23 is located at the middle of the second wing plate 22 and the first wing plate 21 in the first direction.

[0049] In some embodiments, the outrigger 2 further includes a stiffener 24, which connects the second wing plate 22, the web plate 23 and the first wing plate 21, thereby increasing the connection strength and stability of the second wing plate 22, the web plate 23 and the first wing plate 21, increasing the strength and stability of the outrigger 2, and thus helping to improve the strength and stability of the connection between the outrigger 2 and the channel 1 and the cable tray 3.

[0050] Furthermore, the web plate 23 is provided with a plurality of stiffening plates 24 symmetrically arranged on both sides in its thickness direction (i.e., the first direction). The plurality of stiffening plates 24 are arranged at equal intervals along the second direction, thereby further increasing the connection strength of the second wing plate 22, the web plate 23 and the first wing plate 21, further increasing the strength and stability of the support leg 2, and thus further improving the strength and stability of the support leg 2 connecting the groove 1 and the cable tray 3.

[0051] Specifically, each of the second wing plate 22, stiffening plate 24 and first wing plate 21 is connected to the web plate 23 by full penetration welding, which helps to further improve the strength of the connection and enhance the strength and stability of the outrigger 2.

[0052] In some embodiments, the second wing plate 22 is provided with a first connecting hole 221, and the bridge 3 is provided with a second connecting hole 31 and a third connecting hole 32 at both ends in the first direction. The second connecting hole 31 and the third connecting hole 32 are respectively opposite to the first connecting hole 221 of the corresponding second wing plate 22. The third connecting hole 32 is a strip-shaped hole that extends along the first direction. The stirring device 100 further includes a connector (not shown in the figure). The connector is provided in the second connecting hole 31 and the first connecting hole 221, and the connector is provided in the third connecting hole 32 and the first connecting hole 221.

[0053] like Figure 1 and Figure 7 As shown, the second connecting hole 31 is located at the left end of the cable tray 3. The second connecting hole 31 is opposite to the first connecting hole 221 of the second wing plate 22 of the support leg 2 located at the left end of the trough 1. The connector passes through the second connecting hole 31 and the first connecting hole 221 to connect the support leg 2 at the left end and the cable tray 3. The third connecting hole 32 is located at the right end of the cable tray 3. The third connecting hole 32 is opposite to the first connecting hole 221 of the second wing plate 22 of the support leg 2 located at the right end of the trough 1. The connector passes through the third connecting hole 32 and the first connecting hole 221 to connect the support leg 2 at the right end and the cable tray 3.

[0054] The third connecting hole 32 is a strip-shaped hole with a certain size in the first direction. The size of the third connecting hole 32 in the first direction is larger than the size of the first connecting hole 221. The third connecting hole 32 has a certain connection allowance in the first direction, which facilitates the docking of the bridge frame 3 and the support leg 2 when connecting them, thereby improving the ease of assembly of the stirring device 100 of this utility model embodiment.

[0055] Furthermore, the connectors located in the first connecting hole 221 and the second connecting hole 31 are fixedly connected to the second wing plate 22 and the cable tray 3, while the connectors located in the first connecting hole 221 and the third connecting hole 32 are slidably connected to the second wing plate 22 and the cable tray 3. That is, one end (left end) of the cable tray 3 is tightly connected to the support leg 2, while the connection between the other end (right end) of the cable tray 3 and the support leg 2 is not tight, leaving room for movement. Thus, when the load is transmitted to the cable tray 3 and the two support legs 2, the cable tray 3 can move slightly relative to one support leg 2 (the right support leg 2) to offset part of the load. This can reduce to some extent the impact of the bending stress caused by gravity, the torque of the agitator 5, and the horizontal stress impact caused by the alternating expansion and contraction of the cable tray 3 on the upper surface of the tank 1, thereby further increasing the service life of the tank 1.

[0056] Specifically, the second wing plate 22 has multiple first connection holes 221 at both ends in the second direction. Each first connection hole 221 is fitted with a connector. One end (left end) of the cable tray 3 is connected to the support leg 2 through multiple connectors, and the other end (right end) of the cable tray 3 is connected to the support leg 2 through multiple connectors, which helps to improve the stability of the connection between the cable tray 3 and the support leg 2.

[0057] Specifically, the connector is a bolt and nut connector.

[0058] like Figure 7 As shown, the third connecting hole 32 is an oblong hole.
