Description

Technical Field

[0001] This utility model belongs to the technical field of mixers, and specifically relates to a mixer. Background Technology

[0002] For existing mixer products, there are generally parallel shaft mixers and cross shaft mixers. Among them, cross shaft mixers have higher mixing efficiency than parallel shaft mixers because the mixing shaft radius is larger and the mixing range is larger. Therefore, they are widely used in the mixing field.

[0003] However, cross-shaft mixers typically have large mixing dead zones, meaning the effective mixing range is relatively small, which in turn affects the mixer's mixing efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a mixer to solve the problems described in the background section.

[0005] This utility model provides the following technical solution: a mixer, including a mixing support and a mixing tank fixed on the mixing support. The mixing tank is hollow and has a first mixing chamber and a second mixing chamber. The first mixing chamber and the second mixing chamber are connected. A first mixing shaft is rotatably arranged in the first mixing chamber, and a first mixing element is provided on the outer circumferential surface of the first mixing shaft. A second mixing shaft is rotatably arranged in the second mixing chamber, and a second mixing element is provided on the outer circumferential surface of the second mixing shaft. The first mixing element and the second mixing element are staggered and rotate in opposite directions.

[0006] The first stirring chamber and the second stirring chamber are partially overlapped, and the axis of the first stirring chamber and the axis of the second stirring chamber are separated by a first preset gap in the Z-axis direction and a second preset gap in the Y-axis direction. The sides of the first stirring chamber and the second stirring chamber that are far apart from each other are arranged in an arc shape.

[0007] Compared with the prior art, the beneficial effects of this application are as follows: When this application is used, the mixing efficiency can be effectively improved by rotating the first and second mixing components in opposite directions. In addition, there is a certain gap between the first and second mixing chambers in the Z and Y axes. Through the height difference and distance difference between the two, it can be ensured that the material can move more easily in the direction of the center during mixing, thereby improving the mixing speed. Furthermore, by setting the first and second mixing chambers with arc-shaped outer sides, this application can optimize the mixing dead angle, increase the proportion of the effective mixing range, and thus improve the mixing efficiency of the mixer.

[0008] Preferably, the bottom of the stirring bracket is provided with a support foot, which is made of an elastic material.

[0009] Preferably, the support foot is slidably disposed at the bottom of the stirring bracket.

[0010] Preferably, the bottom of the mixing tank is fixedly provided with several evenly distributed arc-shaped strips.

[0011] Preferably, the first agitator is a paddle-type auger, and the second agitator is a spiral-type auger.

[0012] Preferably, the lengths of both the first and second stirring components are less than the distance between the first and second stirring shafts.

[0013] Preferably, the mixing tank has a feed inlet connected to the top and a discharge tank connected to one side.

[0014] Preferably, a control panel for controlling the rotation of the first and second stirring components is provided on one side of the mixing tank. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3As shown, a mixer includes a mixing support 1 and a mixing tank 2 fixed on the mixing support 1. The mixing tank 2 is hollow and has a first mixing chamber 8 and a second mixing chamber 11 inside. The first mixing chamber 8 and the second mixing chamber 11 are connected. A first mixing shaft 10 is rotatably disposed in the first mixing chamber 8, and a first mixing element 9 is disposed on the outer circumferential surface of the first mixing shaft 10. A second mixing shaft 13 is rotatably disposed in the second mixing chamber 11, and a second mixing element 12 is disposed on the outer circumferential surface of the second mixing shaft 13. The first mixing element 9 and the second mixing element 12 are staggered and rotate in opposite directions.

[0028] Specifically, the mixing tank 2 has a hollow barrel structure and is horizontally fixed on the mixing support 1. The mixing support 1 can support and stabilize the structure of the mixing tank 2. The mixing tank 2 is provided with a first mixing chamber 8 and a second mixing chamber 11. The first mixing chamber 8 is provided with corresponding mixing elements, including a first mixing shaft 10 and a first mixing element 9 fixed on the outer circumferential surface of the first mixing shaft 10. The first mixing shaft 10 drives the first mixing element 9 on its outer circumferential surface to rotate, thereby realizing the mixing process. The second mixing chamber 11 is also provided with corresponding mixing elements, including a second mixing shaft 13 and a second mixing element 12 fixed on the outer circumferential surface of the second mixing shaft 13. The second mixing shaft 13 drives the second mixing element 12 on its outer circumferential surface to rotate, thereby realizing the mixing process.

[0029] Specifically, in the actual mixing process, the first mixing element 9 and the second mixing element 12 are staggered and rotate in opposite directions. In practice, both rotate inward, which makes it easier for the material to move towards the middle of the first mixing shaft 10 and the second mixing shaft 13 during the mixing process. The staggered first mixing element 9 and the second mixing element 12 achieve uniform mixing, thereby improving the mixing efficiency.

[0030] The first stirring chamber 8 and the second stirring chamber 11 are partially overlapped, and the axis of the first stirring chamber 8 and the axis of the second stirring chamber 11 have a first preset gap in the Z-axis direction and a second preset gap in the Y-axis direction. The side of the first stirring chamber 8 and the second stirring chamber 11 that are far apart from each other is arranged in an arc shape.

[0031] Specifically, since the first stirring chamber 8 and the second stirring chamber 11 partially overlap, the space utilization rate within the stirring tank 2 can be further improved. Simultaneously, the sides of the first stirring chamber 8 and the second stirring chamber 11 that are furthest from each other are arranged in an arc shape, that is, the outer surfaces of the first stirring chamber 8 and the second stirring chamber 11 are arc-shaped. The arc shape matches the rotation surface of the first stirring element 9 and the rotation surface of the second stirring element 12, thereby optimizing the stirring dead angle, increasing the proportion of the effective stirring range, and thus improving the stirring efficiency of the mixer. Figure 1 From a visual perspective, the horizontal direction is the X-axis, the vertical direction is the Z-axis, and the perpendicular direction is... Figure 1 The plane is oriented in the X-axis direction, and the axis of the first stirring chamber 8 and the axis of the second stirring chamber 11 have a first preset gap in the Z-axis direction and a second preset gap in the Y-axis direction, so that the material can move more easily in the center direction during stirring, thereby increasing the stirring speed.

[0032] It should be noted that in this embodiment, the first preset gap is 150mm and the second preset gap is 400mm.

[0033] In this embodiment, the bottom of the stirring bracket 1 is provided with a support foot 5, which is made of an elastic material;

[0034] Specifically, by setting support feet 5, the vibration generated during the stirring process can be reduced, and the stability during stirring can be improved.

[0035] In this embodiment, the support foot 5 is slidably disposed at the bottom of the stirring bracket 1;

[0036] Specifically, the length of the support leg 5 extending out of the mixing bracket 1 can be controlled by some telescopic control components, thereby controlling the height difference between the mixing bucket 2 and the ground to suit the mixing process under different working conditions. The telescopic control components can be screws or folding umbrella handle structures. Since the sliding control components are commonly used components for controlling telescopic movement in the prior art, they will not be described in detail here.

[0037] In this embodiment, a plurality of evenly distributed arc-shaped strips 7 are fixedly provided at the bottom of the mixing tank 2;

[0038] Specifically, the strength of the mixing tank 2 can be further improved by setting the arc adjustment 7.

[0039] In this embodiment, the first stirring component 9 is specifically a paddle-type auger, and the second stirring component 12 is specifically a spiral-type auger;

[0040] Specifically, by setting the first stirring component 9 as a paddle-type auger and the second stirring component 12 as a spiral-type auger, the stirring rotation coverage area is increased, thereby improving the stirring efficiency.

[0041] In this embodiment, the length of the first stirring member 9 and the length of the second stirring member 12 are both less than the distance between the first stirring shaft 10 and the second stirring shaft 13;

[0042] Specifically, the above settings can prevent collisions between the first stirring element 9 and the second stirring shaft 13, as well as between the second stirring element 12 and the first stirring shaft 10.

[0043] In this embodiment, the mixing tank 2 is provided with a feeding port 4 connected above it, and a feeding tank 6 is provided on one side of the mixing tank 2.

[0044] Specifically, the raw materials are fed into the mixing tank 2 through the feed port 4, and after mixing is completed, they are discharged from the discharge tank 6.

[0045] In this embodiment, a control panel 3 for controlling the rotation of the first stirring element 9 and the second stirring element 12 is provided on one side of the stirring tank 2;

[0046] Specifically, the control panel 3 can be used to control the rotation of the motor, and the motor has two parts that are respectively connected to the first stirring shaft 10 and the second stirring shaft 13. The control panel 3 can control the start and stop of the motor and the rotation direction of the first stirring shaft 10 and the second stirring shaft 13.

[0047] In summary, the mixer in the above embodiments of this utility model, when used in this application, can effectively improve the mixing efficiency by having the first mixing element 9 and the second mixing element 12 rotate in opposite directions. Furthermore, there is a certain gap between the first mixing chamber 8 and the second mixing chamber 11 in the Z-axis and Y-axis directions. Through the height difference and distance difference between the two, it can be ensured that the material can move more easily in the center direction during mixing, thereby increasing the mixing speed. In addition, by setting the first mixing chamber 8 and the second mixing chamber 11 with arc-shaped outer sides, this application can optimize the mixing dead angle, increase the proportion of the effective mixing range, and thus improve the mixing efficiency of the mixer.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
