However, because the mixing blades are mounted on the inner wall of the drum, a dead angle forms between the blades and the drum's inner wall. As the drum rotates, the lees tend to stick to this dead angle. Over time, this leads to insufficient mixing of the lees and low efficiency. Utility Model Content

It should also be noted that the aforementioned Z-axis, Y-axis, and X-axis are merely for the purpose of facilitating the description of the present invention and simplifying the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention.
[0024] It should be noted that the terms "first," "second," and the like in the specification and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.
[0025] Combine Figure 1 As shown, in the first aspect, the utility model provides a mixing blade located inside the mixing drum 10, the mixing blade includes a bracket and a mixing blade body 2, the bracket is used to be connected to the inner wall of the mixing drum 10 in the circumferential direction, the mixing blade body 2 is connected to the bracket, and the mixing blade body 2 is used to be spaced apart from the inner wall of the mixing drum 10.
[0026] Specifically, common rotation modes of the mixing drum 10 include: one in which the mixing drum 10's rotation axis is vertical, another in which the mixing drum 10's rotation axis is horizontal, and yet another in which the mixing drum 10's rotation axis is tilted. Taking the horizontal rotation axis of the mixing drum 10 as an example, the bracket can be a frame composed of one or more connecting parts, such as angle steel and connecting rods. The contact area between the bracket and the circumferential inner wall of the mixing drum 10 is small, and no dead angle is formed. One end of the bracket is welded to the circumferential inner wall of the mixing drum 10 (hereinafter referred to as the "inner wall"), and the other end of the bracket extends toward the axis (rotation axis) of the mixing drum 10. The mixing blade body 2 can be installed at the end of the bracket away from the inner wall by means such as threaded connections, clamping, or welding, so that a certain gap exists between the mixing blade body 2 and the inner wall. During mixing, the mixing drum 10 is driven to rotate, and the mixing drum 10 drives the internal mixing blade body 2 to rotate. The mixing blade body 2 stirs the mash in the mixing drum 10, and during the mixing process, the mash can pass through the gap between the mixing blade body 2 and the inner wall without sticking between the mixing blade body 2 and the inner wall.
[0027] Therefore, in this embodiment, the inner wall of the mixing drum 10 in the circumferential direction is connected to the bracket, and the bracket is connected to the mixing blade body 2, so that the mixing blade body 2 needs to be installed on the inner wall of the mixing drum 10 through the bracket, and then the mixing blade body 2 and the inner wall of the mixing drum 10 are spaced apart, so that there is a gap between the mixing blade body 2 and the inner wall of the mixing drum 10. In this way, direct connection between the mixing blade body 2 and the inner wall of the mixing drum 10 is avoided, thereby avoiding the formation of a dead angle between the mixing blade body 2 and the inner wall of the mixing drum 10, so as to avoid the accumulation of residual germ in the mixing drum 10, thereby improving the mixing effect.
[0028] Optionally, combined Figure 1 、 Figure 2 and Figure 5 As shown, the mixing drum 10 includes a drum cover 20 and a drum bottom 30 located at two axial ends of the mixing drum 10 , and the two axial ends of the mixing blade body 2 are spaced apart from the drum cover 20 and the drum bottom 30 respectively.
[0029] Specifically, the end of the mixing drum 10 facing the negative direction of the X-axis is the drum bottom 30, and the end facing the positive direction of the X-axis is the drum cover 20. The two ends of the mixing blade body 2 in the X-axis direction are spaced apart from the drum cover 20 and the drum bottom 30 respectively.
[0030] In this way, by setting the two ends of the mixing blade body 2 in the axial direction respectively at a distance from the cylinder cover 20 and the cylinder bottom 30 located in the axial direction of the mixing drum 10, there is a gap between the mixing blade body 2 and the cylinder cover 20 and the cylinder bottom 30, thereby eliminating the dead angle between the mixing blade body 2 and the cylinder cover 20 and the cylinder bottom 30, thereby improving the mixing effect of the mixing blade body 2.
[0031] Optionally, combined Figure 1 、 Figure 2 and Figure 5 As shown, multiple mixing blades are arranged around the axis of the mixing drum 10, and the bracket includes a first rod 1 and a second rod 3. The second rod 3 is obliquely placed between the cylinder cover 20 and the cylinder bottom 30, and the first rod 1 is connected between the second rod 3 and the inner wall. The mixing blade body 2 is respectively connected to the first rod 1 and the second rod 3, and extends along the inclined direction of the second rod 3.
[0032] Specifically, the mixing blade body 2 is configured as a plate-like structure. Multiple mixing blades are arranged around the axis of the mixing drum 10. In a single mixing blade, the mixing blade includes two first rods 1, the mixing blade body 2, and a second rod 3. The second rod 3 is tilted between the drum cover 20 and the drum bottom 30 and is respectively connected to the drum cover 20 and the drum bottom 30 by welding. The two first rods 1 are distributed along the tilt direction of the second rod 3. The two first rods 1 are located on the side of the second rod 3 that is away from the axis and are both welded between the second rod 3 and the inner wall. The mixing blade body 2 is respectively connected to the two first rods 1 and the second rod 3 and extends along the tilt direction of the second rod 3.
[0033] In this way, the second rod 3 is placed obliquely between the drum cover 20 and the drum bottom 30, the first rod 1 is connected between the second rod 3 and the inner wall, the mixing blade body 2 is connected to the first rod 1 and the second rod 3 respectively, and the first rod 1 and the second rod 3 form a bracket structure between the drum cover 20 and the drum bottom 30. The mixing blade body 2 is connected to the first rod 1 and the second rod 3 respectively, and extends along the inclined direction of the second rod 3, so that the length of the mixing blade body 2 in the mixing drum 10 is increased, thereby increasing the contact area between the mixing blade body 2 and the grains embryo. The mixing blades are distributed around the axis of the mixing drum 10, so that the mixing effect of the mixing blades can be improved.
[0034] Optionally, combined Figure 1 、 Figure 2 and Figure 5 As shown, the first rod 1 and the second rod 3 are both located on the side of the mixing blade body 2 facing away from the rotation direction of the mixing drum 10 .
[0035] Specifically, the side of the mixing blade body 2 facing the rotation direction of the mixing drum 10 is the contact end with the grain embryo. Therefore, the first rod 1 and the second rod 3 are both located on the side of the mixing blade body 2 facing away from the rotation direction of the mixing drum 10. This prevents the first rod 1 and the second rod 3 from directly contacting the grain embryo and prevents the first rod 1 and the second rod 3 from occupying the area of the mixing blade body 2 facing the contact end. In this way, by positioning the first rod 1 and the second rod 3 on the side of the mixing blade body 2 facing away from the rotation direction of the mixing drum 10, the bracket and the second rod 3 are prevented from occupying the space on the side of the mixing blade body 2 facing the rotation direction of the mixing drum 10, thereby ensuring the mixing effect of the mixing blade body 2.
[0036] Optionally, combined Figure 1 、 Figure 2 and Figure 5 As shown, one end of the mixing blade body 2 facing away from the inner wall is bent toward the rotation direction of the mixing drum 10 .
[0037] Specifically, when the mixing drum 10 rotates counterclockwise around the axis, the end of the mixing blade body 2 away from the inner wall bends counterclockwise; when the mixing drum 10 rotates clockwise around the axis, the end of the mixing blade body 2 away from the inner wall bends clockwise.
[0038] Thus, by bending the end of the mixing blade body 2 facing away from the inner wall along the rotation direction of the mixing drum 10, the bent portion of the mixing blade body 2 can further hinder the flow of the maize germ as the mixing drum 10 rotates, thereby increasing the mixing capacity of the mixing blade body 2, ensuring more uniform mixing of the maize germ and improving the mixing effect of the mixing blade 2. Furthermore, the bent end surface of the mixing blade body 2 in contact with the maize germ is smoother, preventing the mixing blade body 2 from puncturing the maize germ, thereby preventing damage to the maize germ.
[0039] Second, combining Figure 1 and Figure 2 As shown, a mixing drum comprises a drum body and the mixing blades as described above. The mixing blade body 2 of the mixing blade is mounted on the inner wall of the drum body in the circumferential direction through a bracket and is spaced apart from the inner wall of the drum body.
[0040] Specifically, the axis of the drum body is set horizontally, which can also be understood as the axis of the drum body being in the same direction as the X-axis. The mixing blades are installed on the inner wall of the drum body in the circumferential direction through the bracket, namely the first rod 1 and the second rod 3, and a certain distance is left between them and the inner wall of the drum body. In the process of the mixing drum rotating to mix the mash, the mash can flow between the mixing blades and the inner wall, thereby preventing the mash from sticking between the mixing blades and the inner wall.
[0041] In this way, the mixing blades are installed on the inner wall of the drum body in the circumferential direction through the bracket and are spaced apart from the inner wall of the drum body to avoid direct connection between the mixing blades and the inner wall of the mixing drum, thereby eliminating the dead angle between the mixing blades and the inner wall of the mixing drum, avoiding the sticking of the mash, and improving the mixing effect.
[0042] Optionally, a plurality of mixing blades with opposite rotation directions are provided in the drum body.
[0043] Specifically, the spiral direction of a portion of the multiple mixing blades is clockwise, and the spiral direction of another portion is counterclockwise, and the multiple mixing blades are distributed around the rotation axis of the mixing drum.
[0044] In this way, by arranging multiple mixing blades with opposite rotation directions in the drum body, the multiple mixing blades can simultaneously perform mixing movements in two different directions in the drum body to avoid a relatively single mixing direction, thereby improving the mixing effect of the germinated grains.
[0045] Optionally, combined Figures 3 and 4 As shown, a material opening is provided on the circumferential side wall of the drum body, and a material door 40 is provided at the material opening for opening or closing by a driving mechanism.
[0046] Specifically, the drive mechanism may include a drive motor, a sprocket chain transmission mechanism, and a transmission shaft. A material port is provided on the circumferential sidewall of the drum body. The material gate 40 is respectively mounted with rollers at both ends of the drum body in the axial direction. Corresponding rollers are provided on the drum body, and roller chutes extend along the circumference of the drum body. The material gate 40 slides on the sidewall of the drum body along the circumference of the drum body via the rollers and the roller chutes. The transmission shaft is mounted on the drum body via a bearing seat, and the axial direction of the transmission shaft is aligned with the axial direction of the drum body. Two sets of sprocket chain transmission mechanisms are respectively mounted on both ends of the transmission shaft. The two sets of sprocket chain transmission mechanisms are distributed parallel to the rotation direction of the drum body. The material gate 40 is connected between the chains of the two sets of sprocket chain transmission mechanisms. The output end of the drive motor is connected to one of the sprockets in the two sets of sprocket chain transmission mechanisms via a reducer. Taking the forward rotation of the motor to open the material door 40 as an example, the motor rotates forward and drives the sprocket to rotate, and the two sets of sprocket chain transmission mechanisms move synchronously through the transmission shaft, so that the material door 40 gradually slides from the material opening to a position away from the material opening until the material opening is fully opened; when closing the material opening, the drive motor can be reversed.
[0047] In this way, a material port is provided on the drum body, and a material door 40 for opening or closing by a driving mechanism is provided at the material port. The material port can be opened or closed by the material door 40 to facilitate the use of the drum body.
[0048] Optionally, a chain wear-resistant groove may be provided on the roller body, which extends along the movement direction of the chain. Lubricating grease may be provided inside the chain wear-resistant groove, and the chain slides in the chain wear-resistant groove to reduce the wear loss of the chain.
[0049] Optionally, the plurality of mixing blades are distributed on both sides of the material opening along the rotation direction of the drum body, and the plurality of mixing blades located on the same side of the material opening have the same rotation direction.
[0050] Specifically, a guide groove can be formed between two adjacent mixing blades with the same rotation direction. During mixing, as the mixing drum rotates and the weight of the malt grains is applied, the malt grains can flow out of one guide groove at each end, then flow into the next guide groove at each end, and then out of the next guide groove at each end. This process repeats. Under the action of the guide groove, the malt grains can flow out of each guide groove at each end, then flow into the next guide groove at each end, and then flow out of the next guide groove at each end, mixing. After mixing, the malt grains can flow out of the guide groove at each end, and then flow into the next guide groove at each end, mixing. After mixing, the malt grains can flow out of the guide groove at each end, and then out of the guide groove at each end, so that the malt grains can be continuously separated and mixed. In this way, by distributing the multiple mixing blades on both sides of the material opening along the rotation direction of the drum body and the multiple mixing blades on the same side of the material opening having the same rotation direction, the malt grains can flow continuously, thereby improving the mixing effect of the malt grains.
[0051] In a third aspect, a drum mixer comprises the above mixing blades.
[0052] The advantages of the drum mixer over the prior art are the same as those of the mixing blades and will not be described in detail here.
[0053] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
