Description

Technical Field

[0001] This utility model relates to the field of homogenizer technology, specifically to a homogenizing head structure for a homogenizer. Background Technology

[0002] Homogenizers primarily use a pressure system to squeeze, stretch, impact, and crush materials, relying on cavitation and turbulence effects to achieve homogenization. During the homogenization process, a laminar flow effect is generated, and dispersed particles or droplets are sheared and stretched. Homogenizers are mainly used in important fields such as biotechnology, pharmaceuticals, food industry, cosmetics industry, and petrochemicals.

[0003] Generally, a homogenizer includes a reaction vessel and a stirring mechanism, which in turn includes a homogenizing head for stirring the materials inside the reaction vessel. However, commercially available homogenizing heads generally have poor homogenization performance. These heads typically consist of a rotating shaft and a stirring rod positioned outside the shaft, relying solely on the stirring rod to agitate the materials within the reaction vessel, resulting in poor homogenization and impacting product quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, the present invention provides a homogenizing head for a homogenizer, comprising a first mounting plate 1, a fixed cutting wall 2, a rotating shaft 3, and multiple cutting blades 4.

[0025] The first mounting plate 1 is circular in shape and is used to install at the bottom of the reactor. The first mounting plate 1 has a first through hole 11. It should be understood that the first mounting plate 1 can be sealed at the bottom of the reactor by welding or threaded connection.

[0026] The fixed cutting arm 2 is cylindrical and is fixedly installed outside the first through hole 11 on the top surface of the first mounting plate 1 and is used to pass through the reactor. In other words, the fixed cutting arm 2 is housed inside the reactor.

[0027] In this embodiment, the fixed cutting arm 2 is provided with a circular receiving through hole 21, wherein the top end of the fixed cutting arm 2 is provided with a plurality of first flow holes 22 at intervals, and the bottom end of the fixed cutting arm 2 is provided with a plurality of second flow holes 23 at intervals. It should be understood that during homogenization, the material (such as emulsion) enters the receiving through hole 21 through the plurality of first flow holes 22, and flows out through the second flow holes 23 after stirring and cutting.

[0028] Preferably, the first flow hole 22 is circular and the second flow hole 23 is elongated, wherein the width of the second flow hole 23 in the vertical direction is equal to the width of the first flow hole 22 in the vertical direction.

[0029] Furthermore, in some embodiments, the fixed cutting arm 2 is detachably disposed outside the first through hole 11 on the top surface of the first mounting plate 1. Specifically, the top surface of the first mounting plate 1 is also provided with an annular groove surrounding the first through hole 11, and the bottom end of the fixed cutting arm 2 is detachably inserted into the annular groove. Furthermore, the inner wall of the annular groove is provided with a first thread, and the outer wall of the fixed cutting arm 2 is provided with a second thread that is threadedly connected to the first thread (one of the first thread and the second thread is an external thread, and the other of the first thread and the second thread is an internal thread).

[0030] The rotating shaft 3 is rotatably disposed in the receiving through hole 21, wherein one end of the rotating shaft 3 passes through the first through hole 11, and the other end of the rotating shaft 3 protrudes from the top surface of the first mounting plate 1, that is, the other end of the rotating shaft 3 is received in the receiving through hole 21.

[0031] Multiple cutting blades 4 are spaced apart on the outer wall of the rotating shaft 3 so that the rotating shaft 3 can synchronously drive the multiple cutting blades 4 to rotate. It should be understood that the cutting blades 4 can stir and cut the material entering the receiving through hole 21.

[0032] In this embodiment, the end face of the cutting blade 4 away from the rotating shaft 3 is clearance-fitted with the inner wall of the receiving through hole 21 of the fixed cutting arm 2. It can be understood that the high-speed rotation of the rotating shaft 3 can drive the multiple cutting blades 4 arranged around the outer wall of the rotating shaft 3 to perform high-speed stirring and cutting of the material in the fixed cutting arm 2, and the gap between the cutting blade and the inner wall of the fixed cutting arm 2 can better homogenize the material, so that the material can be crushed more evenly, and the cut material can also be homogenized more evenly.

[0033] Preferably, the end face of the cutting blade 4 away from the rotating shaft 3 is arc-shaped.

[0034] Furthermore, the cutting blade 4 is rectangular arc-shaped. Of course, in other embodiments, the cutting blade 4 can also be other shapes, such as rectangular.

[0035] Furthermore, in order to improve the mixing effect, multiple needles of different lengths are arranged at intervals on both sides of the blade 4, so that when the blade 4 is driven by the rotating shaft 3, the material in the receiving through hole 21 can be pierced and mixed by the needles.

[0036] Preferably, the length of the other end of the rotating shaft 3 housed in the receiving through hole 21 is less than the depth of the receiving through hole 21, and the length of the other end of the rotating shaft 3 housed in the receiving through hole 21 is the same as the height of the cutting blade 4.

[0037] In this embodiment, the distance between the end face of the cutting blade 4 away from the rotating shaft 3 and the inner wall of the receiving through hole 21 of the fixed cutting arm 2 is in the range of 0.1-0.5 mm. The material can be ground between the end face of the cutting blade 4 away from the rotating shaft 3 and the inner wall of the receiving through hole 21 of the fixed cutting arm 2, allowing some particulate material to enter the receiving through hole 21 and be sheared by the cutting blade 4 and the fixed cutting arm 2, thereby making the particulate material crushed faster.

[0038] It should be understood that in some embodiments, the cutting blade 4 includes a first cutting blade, a second cutting blade, and a third cutting blade, wherein the distance between the end face of the first cutting blade away from the rotating shaft 3 and the inner wall of the receiving through hole 21 of the fixed cutting arm 2, the distance between the end face of the second cutting blade away from the rotating shaft 3 and the inner wall of the receiving through hole 21 of the fixed cutting arm 2, and the distance between the end face of the third cutting blade away from the rotating shaft 3 and the inner wall of the receiving through hole 21 of the fixed cutting arm 2 are all different, so that the first cutting blade, the second cutting blade, and the third cutting blade can be used to grind and cut granular materials of different sizes.

[0039] Alternatively, in some embodiments, multiple cutting blades 4 are detachably spaced on the outer wall of the rotating shaft 3, so that different types of cutting blades can be replaced as needed.

[0040] In this embodiment, the first through hole 11 is circular in shape, and one end of the rotating shaft 3 extends into the first through hole 11 with a cylindrical extension post 31 that passes through the first through hole 11. The outer diameter of the extension post 31 is equal to the diameter of the first through hole 11, which makes the first through hole have a good sealing effect and makes it difficult for the material in the reactor to be discharged from the first through hole 11.

[0041] Preferably, a sealing ring is provided between the outer wall of the extension column 31 and the inner wall of the first through hole 11. It should be understood that when the homogenizing head is cutting or homogenizing emulsion, the sealing ring between the extension column 31 and the first through hole 11 can prevent emulsion leakage.

[0042] Furthermore, the homogenizing head used in this homogenizer also includes a second mounting plate 5, a connecting cylinder 6, and a third mounting plate 7.

[0043] The second mounting plate 5 is threadedly connected to the first mounting plate 1.

[0044] One end of the connecting cylinder 6 is located on the bottom surface of the second mounting plate 5.

[0045] The third mounting plate 7 is disposed at the other end of the connecting cylinder 6. The third mounting plate 7 is used to mount on the top surface of the drive motor, and the drive shaft of the drive motor passes through the third mounting plate 7, the connecting cylinder 6, and the second mounting plate 5 and is fixedly connected to the extension column 31 (e.g., the drive shaft of the drive motor and the extension column 31 are connected by a threaded connection). That is to say, the rotating shaft 3 is driven by the drive shaft of the drive motor. In addition, the drive motor in this application can be implemented using products in the prior art, and its principle and structure will not be described in detail here.

[0046] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
