Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of processing equipment, and specifically relates to a homogenizing equipment. Background Art
[0002] Homogenization is a technology that is often used in the food or chemical industry. Homogenizing equipment can generally be divided into two categories: rotary and pressure types. Rotary homogenizing equipment is composed of a rotor or a rotor-stator system, which directly transfers mechanical kinetic energy to the material, such as a mixer or an emulsifying pump. The pressure homogenizing equipment first allows the liquid medium to obtain high-pressure energy. When this high-pressure liquid passes through the homogenizing mechanism, the high-pressure energy is converted into kinetic energy, thereby obtaining the effect of fluid force, such as a high-pressure homogenizer. When the existing rotary homogenizing equipment is performing homogenization, the output head of the material after homogenization is low, and a boosting device needs to be installed on the output pipeline to perform secondary boosting on the material before transportation, which results in high equipment costs. Utility Model Content
[0003] The technical problem to be solved by the present application is that the existing rotary homogenizing equipment needs to be equipped with a booster device on the output pipeline for secondary boosting, which leads to high equipment cost. A homogenizing equipment with lower cost and output head that can meet the requirements is provided.

[0012] Furthermore, it also includes a second impeller, which is arranged at the part of the rotating shaft extending into the processing chamber, and the second impeller corresponds to the discharge port and can guide the material to be transported to the discharge port.
[0013] Furthermore, each of the shearing knives is arranged to be inclined relative to the axial direction of the rotating shaft, and one end of each of the shearing knives is connected to the inner wall of the processing chamber, and the other end extends in a direction opposite to the material conveying direction.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] like Figure 1As shown, an embodiment of the present application provides a homogenizing device 10 , including a housing 11 , a rotating shaft 12 , a first homogenizing structure 13 and a second homogenizing structure 14 .
[0028] The shell 11 has a processing chamber 111 and a feed port 112 and a discharge port 113 connected to the processing chamber 111. One end of the rotating shaft 12 passes through the shell 11 and extends into the processing chamber 111. The first homogenizing structure 13 and the second homogenizing structure 14 are both connected between the rotating shaft 12 and the inner wall of the processing chamber 111, and the first homogenizing structure 13 and the second homogenizing structure 14 are arranged at intervals along the axial direction of the rotating shaft 12 to divide the processing chamber 111 into three chambers. The feed port 112 and the discharge port 113 are connected to the chambers at both ends. The first homogenizing structure 13 and the second homogenizing structure 14 are both provided with homogenizing channels connecting the spaces on both sides. The material enters the processing chamber 111 through the feed port 112, and then the material passes through the homogenizing channels of the first homogenizing structure 13 and the second homogenizing structure 14 in sequence to perform two-stage homogenization treatment, and the material after the two-stage homogenization treatment is discharged through the discharge port 113.
[0029] Furthermore, the homogenizing device further includes a first impeller 15 and a plurality of shearing knives 16. The first impeller 15 is disposed on the rotating shaft 12 and is located between the first homogenizing structure 13 and the second homogenizing structure 14. During the rotation of the first impeller 15, the material can be guided to be transported along the axial direction of the rotating shaft 12. The plurality of shearing knives 16 are disposed on the inner wall of the processing chamber 111 and are located between the first homogenizing structure 13 and the second homogenizing structure 14 to shear the material flowing through.
[0030] With the above homogenizing device, the material enters the processing chamber 111 from the feed port 112, and the material is discharged from the discharge port 113 after being subjected to two-stage homogenization treatment by the first homogenizing structure 13 and the second homogenizing structure 14 in the processing chamber 111. When the material is transported between the first homogenizing structure 13 and the second homogenizing structure 14, the rotating first impeller 15 can guide the material to be transported along the axial direction of the rotating shaft 12, and pressurize the material transportation, thereby increasing the output head of the material discharged from the discharge port 113, ensuring that the material output head meets the requirements, and there is no need to set a pressurizing device on the output pipeline, thereby reducing the equipment cost.
[0031] In addition, a shearing knife 16 is arranged between the first homogenizing structure 13 and the second homogenizing structure 14. During the rotation of the first impeller 15, part of the material will flow to the shearing knife 16 due to the centrifugal force. The shearing knife 16 shears the material, thereby further improving the homogenizing effect.
[0032] Specific to Figure 1 In the illustrated embodiment, the first impeller 15 is an axial flow impeller to guide the material to be transported along the axial direction of the rotating shaft 12 .
[0033] In one embodiment, the feed port 112 is connected to the space on the side of the first homogenizing structure 13 away from the second homogenizing structure 14, and the discharge port 113 is connected to the space on the side of the second homogenizing structure 14 away from the first homogenizing structure 13, that is, after the material enters the processing chamber 111, it is first homogenized by the first homogenizing structure 13 and then homogenized by the second homogenizing structure 14.
[0034] Furthermore, during the rotation of the first impeller 15 , the material can be guided to be transported from the first homogenizing structure 13 to the second homogenizing structure 14 , so as to increase the pressure of the material during transportation.
[0035] In one embodiment, each shearing knife 16 is arranged to be inclined relative to the axial direction of the rotating shaft 12, and one end of each shearing knife 16 is connected to the inner wall of the processing chamber 111, and the other end extends in the direction opposite to the material conveying direction, that is, extends in the direction of the incoming material, thereby shearing the material and improving the homogenization effect of the material.
[0036] It is understandable that the shearing knife 16 has a blade at one end away from the inner wall of the processing chamber 111, and the blade faces the direction of the incoming material, so that the material can be sheared more conveniently. At the same time, during the rotation of the first impeller 15, the material at the edge of the first impeller 15 will be affected by the centrifugal force, so that it can flow toward the shearing knife 16, and then can be sheared by the shearing knife 16. In addition, during the rotation of the first impeller 15, the material can also be hit, and large particles of material can be broken up to a certain extent, thereby improving the homogenization effect.
[0037] Furthermore, each shearing knife 16 is provided with a plurality of shearing holes along the thickness direction thereof, which can not only make the shearing knife 16 lighter, but also allow the material to be sheared through the edges of the shearing holes, further improving the shearing effect.
[0038] In one embodiment, the first homogenizing structure 13 includes a first stator 131 and a first rotor 132. The first stator 131 is fixedly connected to the inner wall of the processing chamber 111, and the first rotor 132 is fixedly connected to the rotating shaft 12, and the first stator 131 and the first rotor 132 cooperate with each other to form the above-mentioned homogenizing channel.
[0039] Furthermore, the second homogenizing structure 14 includes a second stator 141 and a second rotor 142. The second stator 141 is fixedly connected to the inner wall of the processing chamber 111, and the second rotor 142 is fixedly connected to the rotating shaft 12. The second stator 141 and the second rotor 142 cooperate with each other to form the above-mentioned homogenizing channel.
[0040] It can be seen that when the material passes through the homogenizing channel, the rotor rotates relative to the stator to grind the material, disperse the material, and make the material uniform. At the same time, the gap between the stator and the rotor, that is, the size of the homogenizing channel, can be determined according to the specific material composition.
[0041] In one embodiment, the first homogenizing structure 13 has a first homogenizing channel 133, and the second homogenizing structure 14 has a second homogenizing channel 143. The first homogenizing channel 133 and the second homogenizing channel 143 extend in a zigzag manner to extend the path, extend the time for the material to flow, and improve the homogenization effect.
[0042] Specific to Figure 1 In the illustrated embodiment, a plurality of annular protrusions are provided on both the stator and the rotor, and the annular protrusions on the stator and the annular protrusions on the rotor are arranged opposite to each other and staggered with each other, that is, an annular protrusion on the stator can be inserted between two adjacent annular protrusions on the rotor, thereby forming a zigzag extending homogeneous channel.
[0043] In one embodiment, the distance between the outlet end B1 of the first homogenizing channel 133 and the rotating shaft 12 is greater than the distance between its inlet end A1 and the rotating shaft 12, and the distance between the inlet end A2 of the second homogenizing channel 143 and the rotating shaft 12 is greater than the distance between the outlet end B2 and the rotating shaft 12. Figure 1 As shown, the outlet end B2 of the first homogenizing channel 133 and the inlet end A2 of the second homogenizing channel 143 are both arranged close to the inner wall of the processing chamber 111, so that the material between the first homogenizing structure 13 and the second homogenizing structure 14 can be close to the shearing knife 16, which facilitates the shearing knife 16 to shear the material, improve the shearing effect, and further improve the homogenizing effect.
[0044] In one embodiment, the homogenizing device further includes a second impeller 17, which is disposed at the portion of the rotating shaft 12 extending into the processing chamber 111 and corresponds to the discharge port 113. The second impeller 17 can guide the material to be transported to the discharge port 113 to further increase the output head of the material discharged from the discharge port 113. Figure 1 In the illustrated embodiment, the second impeller 17 is a centrifugal impeller.
[0045] In one embodiment, the homogenizing device further comprises a driving member 18, which is connected to an end of the rotating shaft 12 away from the housing 11 to drive the rotating shaft 12 to rotate. Figure 1 In the illustrated embodiment, the driving member 18 is a motor, the rotating shaft 12 is rotatably arranged via a bearing, and the motor is connected to the rotating shaft 12 via a coupling.
[0046] The homogenizing device provided in this application has at least the following advantages:
[0047] 1. The first impeller 15 guides the material in the processing chamber 111 to be transported along the axial direction of the rotating shaft 12, thereby pressurizing the material and increasing the output head of the material discharged from the discharge port 113, ensuring that the material output head meets the requirements. In addition, compared with adding a pressurizing device to the output pipe, the cost of the homogenizing device is lower;
[0048] 2. The second impeller 17 guides the material to be discharged from the discharge port 113, further increasing the output head of the material;
[0049] 3. A plurality of shearing knives 16 are provided on the inner wall of the processing chamber 111 to shear the material and further improve the homogenization effect.
[0050] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
