Description

Technical Field

[0001] This utility model relates to a vertical mixer, and more particularly to a mixing tank structure for a vertical mixer. Background Technology

[0002] The mixing tank of a vertical mixer has an upward-facing opening. The mixing shaft is vertical and enters the mixing tank from the opening downwards. Blades are fixedly connected to the portion of the shaft inside the tank, and mixing is achieved through the rotation of these blades. To improve mixing efficiency, the mixing tank also has a heating function. This is typically achieved by installing heating rods outside the tank or by using piping to transfer heated oil or other media to the mixing tank. However, existing mixing tanks suffer from relatively large size and area, resulting in high energy consumption during the heating process. Utility Model Content

[0016] Please see Figure 1 , Figure 2 and Figure 3 A vertical mixer has a mixing tank structure comprising: a tank body 1, two liquid inlet pipes 2, and a heating system 3.

[0017] The top opening of the tank 1 means that the tank 1 is composed of four vertical side plates and a bottom plate.

[0018] The top of the tank 1 has a mounting position 1A for mounting the stirring shaft. More specifically, the stirring shaft is rotatably connected to the mounting plate, and the motor that drives the stirring shaft is also mounted on the mounting plate. The mounting position 1A can be a mounting hole, and the mounting plate is fixedly connected to the mounting position 1A with fasteners.

[0019] Please see Figure 1 In some embodiments, the top opening of the tank 1 has an outward-facing flange 1B. That is, the top edges of all four vertical outer walls of the tank 1 are formed with flanges 1B facing outwards. There are two mounting positions 1A, which are respectively set at the flanges 1B corresponding to the two opposite vertical outer walls.

[0020] Setting the flange 1B improves the support of the tank body 1 for the mounting plate, stirring shaft, and motor, making the connection more secure and the stirring shaft more stable when rotating.

[0021] Please see Figure 1 and Figure 6In some embodiments, in addition to the outward-facing flange 1B at the top opening of the tank body 1, a set of lifting lugs 1C are also fixed to the two opposing vertical outer walls of the tank body 1. More specifically, the lifting lugs 1C are welded and fixed between the vertical outer walls and the flange 1B. The lifting lugs 1C also correspond to the installation position 1A.

[0022] The lifting lug 1C facilitates the lifting of the trough 1. In addition, the lifting lug 1C can also reinforce the installation position 1A, acting as a reinforcing rib.

[0023] Please see Figure 1 The tank 1 has multiple first feed inlets 1E on one of its vertical outer walls near the top. The first feed inlets 1E may have flanges. After connecting to the conveying pipe, the material to be stirred is sent into the tank 1 by a pump.

[0024] One of the vertical outer walls of the tank 1 has a first discharge port 1F located at the lower part. The first discharge port 1F may have a flange. After connecting to the feeding pipe, the opening / closing of the first discharge port 1F is controlled by a valve.

[0025] Please see Figure 1 and Figure 3 Both inlet pipes 2 are inverted F-shaped, with a vertical first port 2A, a horizontal upper port 2B, and a horizontal lower port 2C, arranged sequentially from top to bottom. The two inlet pipes 2 are fixedly connected to two opposite vertical outer walls of the tank 1, meaning that both the upper port 2B and the lower port 2C of the inlet pipe 2 connect to the inside of the tank 1. The two inlet pipes 2 are staggered; that is, in a top-down view, one inlet pipe 2 is closer to the first side, and the other inlet pipe 2 is closer to the second side.

[0026] The first port 2A may have a flange. The first port 2A is higher than the top opening of the tank body 1, which facilitates the connection of the first port 2A to the liquid delivery pipeline. After the material delivery pipeline is connected, the solution is sent into the tank body 1 from the lower port 2C by a pump.

[0027] The upper inlet 2B is lower than any of the first feed inlets 1E, meaning the upper inlet 2B is lower than the lowest first feed inlet 1E. Before stirring, the liquid level in the stirring tank corresponds to the middle of the upper inlet 2B.

[0028] The lower outlet 2C is higher than the first discharge outlet 1F, so that the lower outlet 2C will not affect the discharge of the first discharge outlet 1F.

[0029] Please see Figure 1 In some embodiments, multiple first inlet ports 1E, first outlet ports 1F, and one of the liquid inlet pipes 2 are located on the same vertical outer wall of the tank body 1.

[0030] In this way, among the four vertical side plates of the tank body 1, two vertical side plates need to be machined with holes, while the other two vertical side plates do not need to be machined with holes, making the machining process more convenient.

[0031] The heating system 3 is fixedly connected to the tank 1 and is used to heat the tank 1. That is, it conducts heat to the liquid being stirred inside the tank 1 through the tank 1.

[0032] Multiple first feed ports 1E are used to feed materials into the tank 1, two liquid inlet pipes 2 are used to feed solutions into the tank 1, and a discharge pipe is used for discharging. This makes the size and area of ​​the tank 1 more compact, and the heating system 3 has higher heating efficiency and lower energy consumption. During the stirring process, under the action of the stirring blades, the liquid in the tank 1 flows through the upper port 2B and the lower port 2C in the liquid inlet pipe 2, which improves the stirring efficiency, reduces the stirring time, and lowers the energy consumption of the heating system 3.

[0033] Please see Figure 3 and Figure 4 In some embodiments, the heating system 3 includes: a mesh pipe network 31 and multiple connecting pipes 32. The mesh pipe network 31 is composed of multiple welded pipe segments that are interconnected. The mesh pipe network 31 has multiple connecting ports on each of the four vertical outer walls of the tank 1. The multiple connecting pipes 32 are fixedly connected to the four vertical outer walls of the tank 1. The number of connecting pipes 32 is the same as the number of connecting ports in the mesh pipe network 31. The lower end of the connecting pipe 32 connects to the connecting port of the mesh pipe network 31. More specifically, the lower end of the connecting pipe 32 and the connecting port can both be cut at a 45-degree angle, fitted together, and then welded.

[0034] Accordingly, the heating system 3 has a second inlet pipe 3A and a second outlet pipe 3B, both of which are connected to one of the connecting pipes 32. The second inlet pipe 3A may be slightly higher than the second outlet pipe 3B. The second inlet pipe 3A may have a flange. After connecting to the oil supply pipe, the heated oil is pumped into the heating system 3. As the pump continues to deliver the oil, the second outlet pipe 3B allows the oil to overflow, thus maintaining the oil in the heating system 3 at a suitable temperature.

[0035] The four vertical side plates and bottom plate of the tank 1 can be hollow, for accommodating the mesh pipes 31 and multiple connecting pipes 32. Please refer to [link / reference]. Figure 3 and Figure 5 Alternatively, the mesh pipes 31 and multiple connecting pipes 32 can all be covered with protective strips 4; the protective strips 4 have a concave cross-section and are fixedly connected to the tank 1 to form a cavity. Correspondingly, a layer of thermal insulation material can be installed on the inner wall of the protective strips 4.

[0036] Please see Figure 5In some embodiments, the heating system 3 includes a mesh pipe network 31 and multiple connecting pipes 32. The four vertical outer walls of the tank 1 have multiple vertical recessed grooves 1G. Correspondingly, through the recessed grooves 1G, a protrusion 1H is formed on the inner wall of the tank 1. The connecting pipes 32 are located within the recessed grooves 1G, improving the heat conduction of the connecting pipes 32, the tank 1, and the liquid within the tank 1.
