For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0029] A premixing feeding device for stirring milk powder, the structure of which can be Figure 1-Figure 5 As shown in the figure, in this embodiment, the premixing feeding device for milk powder stirring includes: a feeding main pipe, a feeding branch pipe, a connector 3 and a distribution component, wherein the feeding main pipe is used to convey materials to the stirring device and provide space for premixing of the main material and the auxiliary material, the feeding branch pipe is used to convey the auxiliary material into the feeding main pipe, the connector 3 is used to achieve the connection between the feeding branch pipe and the auxiliary material air delivery pipeline, and the distribution component is used to evenly disperse the auxiliary material into the feeding main pipe, thereby improving the premixing effect of the main material and the auxiliary material.
[0030] Specifically, during assembly, one end of the main feed pipe should be connected to the main material air delivery pipeline through a flange, so that the main material air delivery pipeline uses high-pressure gas as a delivery medium to deliver the main material of the formula milk powder (such as whey powder or milk powder) into the interior of the device. The feed branch pipe should be arranged on the side wall of the main feed pipe, the bottom end of the feed branch pipe is connected to the main feed pipe, the connector 3 is detachably arranged on the top of the feed branch pipe, and the connector 3 is connected to the auxiliary material air delivery pipeline, so that the auxiliary material air delivery pipeline uses high-pressure gas as a delivery medium to deliver the auxiliary material of the formula milk powder (such as vitamin powder, trace element minerals or probiotics, etc.) into the interior of the device. Correspondingly, the other end of the main feed pipe should also be connected to the feed inlet of the stirring device through a flange, so that the main material and the auxiliary material can smoothly enter the interior of the stirring device after the pre-mixing is completed inside the device.
[0031] Figure 3 is a cross-sectional view of the device, Figure 5 is a schematic diagram of the structure of the cloth component, such as Figure 3 and Figure 5 As shown, in this embodiment, the material distributing assembly includes a distributing barrel 4 and a connecting shaft 5, wherein the distributing barrel 4 is rotatably arranged inside the feed branch pipe, the top end of the connecting shaft 5 is connected to the bottom surface of the distributing barrel 4, and the axis of the connecting shaft 5 is perpendicular to the axis of the feed main pipe. An impeller 6 is also arranged on the connecting shaft 5, and when the distributing barrel 4 is installed inside the feed branch pipe, the impeller 6 will be placed inside the feed main pipe. In addition, in order to facilitate the auxiliary material to enter the feed main pipe through the distributing assembly, a feed hole 41 should be arranged at the top end of the distributing barrel 4, and a plurality of distributing holes 42 are arranged on the bottom surface of the distributing barrel 4. When the main material and the high-pressure gas enter the feed main pipe, the impeller 6 will drive the distributing barrel 4 to rotate under the action of the gas flow. At this time, the auxiliary material entering the inside of the distributing barrel 4 will fall into the feed main pipe along the distributing hole 42 as the distributing barrel 4 rotates, so that the auxiliary material is evenly distributed inside the feed main pipe, and the main material and the auxiliary material are pre-mixed during the feeding process.
[0032] Optionally, in order to improve the effect of the auxiliary material entering and exiting the distributing tube 4, a material guide conical surface 411 may be provided on the inner side wall of the feed hole 41, and the bottom surface of the distributing tube 4 may be set as a conical surface. In the process of the auxiliary material entering the distributing tube 4, the material guide conical surface 411 can reduce the difficulty of the auxiliary material entering and accelerate the speed of the auxiliary material entering the distributing tube 4. When the auxiliary material leaves the distributing tube 4, since the bottom surface of the distributing tube 4 is a conical surface, it can prevent the auxiliary material from being accumulated inside the distributing tube 4, and ensure that the auxiliary material inside the distributing tube 4 smoothly enters the main feeding pipe.
[0033] Since the cloth assembly will rotate during the material conveying process, in order to prevent the cloth assembly from moving abnormally during the rotation process, the bottom end of the connecting shaft 5 can be set to a spherical surface. Accordingly, a hemispherical groove 15 for accommodating the bottom end of the connecting shaft 5 should be provided on the inner side wall of the feeding main pipe. After the cloth assembly is assembled, the spherical surface at the bottom end of the connecting shaft 5 will be placed inside the hemispherical groove 15. The cooperation between the spherical surface and the hemispherical groove 15 can not only position the bottom end of the cloth assembly, but also reduce the friction resistance between the connecting shaft 5 and the feeding main pipe, so as to facilitate the rotation of the cloth assembly.
[0034] In addition, in order to prevent the cloth assembly from moving along the axial direction of the feeding branch pipe during the rotation process, the feeding branch pipe of this embodiment may include a threaded section 21 and a receiving section 22, wherein the threaded section 21 is arranged at the top of the receiving section 22, and the bottom end of the connector 3 is provided with a threaded pipe 31 matched with the threaded section 21, the inner diameter of the threaded section 21 should be larger than the inner diameter of the receiving section 22, the outer diameter of the cloth barrel 4 should be equal to the inner diameter of the receiving section 22, and the inner diameter of the threaded pipe 31 is equal to the inner diameter of the cloth barrel 4. During assembly, the staff can first rotatably install the cloth barrel 4 in the receiving section 22, and then screw the threaded pipe 31 at the bottom end of the connector 3 into the threaded section 21. At this time, the bottom end surface of the threaded pipe 31 will limit the top surface of the cloth barrel 4 to prevent the cloth assembly from axially moving during the working process.
[0035] Figure 4 This is a cut-away internal view of the main feed pipe and the branch feed pipe. To further enhance the premixing effect of the main material and the auxiliary material, the main feed pipe in this embodiment may include a first mixing section 11, a reducing section 12, and a second mixing section 13 that are sequentially connected, wherein the first mixing section 11 is connected to the main material air delivery pipeline, the second mixing section 13 is connected to the auxiliary material air delivery pipeline, the branch feed pipe is connected to the first mixing section 11, and the inner diameter of the first mixing section 11 is greater than the inner diameter of the second mixing section 13.
[0036] After the main material and the auxiliary material enter the device, the materials will be preliminarily mixed in the first mixing section 11 through the rotation of the material distribution component. Since the inner diameter of the first mixing section 11 is larger than the inner diameter of the second mixing section 13, the inner diameter of the variable diameter section 12 will gradually decrease. When the preliminarily mixed materials pass through the variable diameter section 12, the reduction in the inner diameter of the variable diameter section 12 can speed up the flow of the materials and form turbulence inside the materials, further increasing the mixing uniformity of the main material and the auxiliary material, and finally entering the stirring device along the second mixing section 13.
[0037] As an optional implementation of this embodiment, a spiral guide bar 14 may be further provided on the inner wall of the second mixing section 13. When the mixed material enters the second mixing section 13, the spiral guide bar 14 can form a vortex inside the mixed material, thereby further improving the mixing effect between the main material and the auxiliary material, and further improving the pre-mixing degree of the material.
[0038] The effects of the above scheme are described below:
[0039] This embodiment provides a premixing feeding device for stirring milk powder, which can drive the distribution component to rotate through the medium conveying inside the feeding main pipe, and can make the auxiliary material enter the feeding main pipe evenly through the rotation of the distribution component, so as to achieve the premixing of the main material and the auxiliary material during the feeding process, thereby reducing the subsequent stirring workload of the stirring equipment. In addition, the feeding main pipe of the device includes a variable diameter section and a second mixing section, and a spiral guide strip is provided inside the second mixing section. The variable diameter section can increase the flow rate of the material, further improve the mixing uniformity between the main material and the auxiliary material, and the spiral guide strip can make the mixed material form a vortex, thereby further improving the mixing effect between the main material and the auxiliary material.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
