Description

Technical Field

[0001] This utility model relates to the field of powder processing, and in particular to a centrifuge guide structure for peptide powder. Background Technology

[0002] Currently, peptide powder, due to its poor flowability, tendency to agglomerate, and lightweight characteristics, easily accumulates at the blade roots and inner wall of the drum during centrifugation, forming a solid ring layer. This prevents smooth material discharge, increases the moisture content of the slag, and severely affects separation efficiency and powder quality. Simultaneously, peptide powder may contain hard particles, which can cause wear on the outer circumference and forward-moving surface of the blades upon contact. Wear on the outer circumference increases the gap between the blade and the central tube, exacerbating accumulation, while wear on the forward-moving surface can thin the blades or even cause them to break, potentially leading to equipment jamming or failure, threatening production safety. These characteristics of peptide powder make it difficult for traditional centrifuges to avoid accumulation and wear problems, reducing equipment efficiency, increasing maintenance costs, and affecting production stability and product quality.

[0003] To overcome the above-mentioned shortcomings, the inventors invented a centrifuge guiding structure for peptide powder. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a centrifuge guide structure for peptide powder, which reduces the wear of peptide powder on the outer circle of the blade and the wear on the blade in the forward direction, thus avoiding the accumulation and wear problems of traditional centrifuges.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A centrifuge guide structure for peptide powder includes a central tube, blades, a conical spiral section, and a guide device. The central tube has helical blades arranged axially around it, each blade comprising a straight spiral section and a conical spiral section. A guide device is located at the junction of the central tube and the straight spiral section. The guide device includes a feed inlet, a guide channel, and a guide arc surface.

[0007] The front end of the feed inlet is provided with a guide arc surface, and the rear end of the feed inlet is provided with a guide channel. Through the guide arc surface, the feed inlet and the guide channel, the material can be guided along the direction of the blade; the conical spiral section of the blade has an oblique stepped shape on both sides.

[0008] As a further implementation, the radial width of the blade is one-third to one-half the length of the feed inlet.

[0009] As a further implementation, the stepped thickness on both sides of the blade is 1~2mm.

[0010] As a further implementation, the guide channel is arc-shaped, and the final output angle of the guide channel is on the same plane as the blade angle.

[0011] As a further implementation, the axis of rotation of the blade is located on the cross-section of the central tube.

[0012] As a further implementation, the oblique steps on both sides of the blade are gradually deformed, and the thickness of the oblique steps gradually decreases.

[0013] As a further implementation, the opening of the guide arc surface is oriented perpendicular to the axis of the central tube.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) This utility model, through the design of the guiding device (including the guiding arc surface, the feed port and the guiding channel), adjusts the powder from disordered flow to enter the straight spiral section in the same direction as the blade angle, thereby avoiding the powder directly impacting the blade and reducing wear. The blade is designed as a slanted step shape and a gradually changing thickness, which further reduces the impact force of the powder on the blade and extends the service life of the blade. The coordinated design of the guiding device and the blade (the radial width of the blade is one-third to one-half of the length of the guiding device) provides a large space, allowing the powder to flow smoothly and be discharged in time, avoiding the accumulation of powder at the root of the blade, thereby improving the separation efficiency of the equipment, and at the same time reducing the wear of peptide powder on the outer circle of the blade.

[0016] (2) The blades of this utility model are designed with sharp, sloping steps on both sides, which can break up powder clumps and prevent powder clumps from clogging the equipment cavity, thus helping to achieve uniform and efficient centrifugal separation. The powder enters the blades through the arc design of the guide channel and the output direction matched with the blade angle, making the force on the powder more uniform during centrifugation and improving centrifugation efficiency. The guide device is fixed by bolts, which is simple in design and easy to disassemble, making it easier to clean the solid powder remaining in the equipment. This effectively avoids powder accumulation on the blades, reduces wear on the blades in the forward direction, and avoids the accumulation and wear problems of traditional centrifuges.

[0022] Example

[0023] This embodiment provides a centrifuge guide structure for peptide powder, such as... Figure 1 and Figure 2 as well as Figure 3 As shown, it includes a central tube 1, blades 2, a conical spiral section 3, and a guide device 4. The central tube 1 is provided with blades 2 arranged in a spiral shape around the central tube 1 axially. The blades 2 include a straight spiral section 10 and a conical spiral section 3. A guide device 4 is provided at the junction of the central tube 1 and the straight spiral section 10. The guide device 4 is connected to the central tube 1 through bolt fixing holes. The guide device 4 includes a feed inlet 6, a guide channel 5, and a guide arc surface 7. The front end of the feed inlet 6 is provided with the guide arc surface 7, and the rear end of the feed inlet 6 is provided with the guide channel 5. Through the guide arc surface 7, the feed inlet 6, and the guide channel 5, the material can be guided along the direction of the blades 2. The conical spiral section 3 of the blades 2 has oblique stepped sides.

[0024] The radial width of blade 2 is one-third to one-half the length of guide device 4, which provides a relatively large space for the flow of powder, ensuring that the powder can be discharged in time. The solid phase experiences less resistance when moving outward under centrifugal force, and is more easily thrown to the outermost side, preventing it from accumulating at the root of blade 2 and causing severe wear on blade 2. At the same time, it also reduces the processing area of ​​blade 2, which helps to reduce material and processing costs.

[0025] The stepped thickness on both sides of blade 2 is 1~2mm. This design saves the overall material of blade 2, and the oblique stepped blade 2 design has relatively less impact on powdery materials, thus resulting in less wear.

[0026] The guide channel 5 is arc-shaped, and the final output angle of the guide channel 5 is on the same plane as the blade angle. This is so that the powder can eventually cut into the straight spiral section 10 of the blade 2 with the blade angle. This reduces the impact of the powder on the blade 2, and also reduces the impact on the straight spiral section 10.

[0027] The axis of rotation of blade 2 is located on the cross-section of the central tube. This is to achieve a stable setting of blade 2 and to achieve efficient mixing of powder.

[0028] The inclined steps on both sides of blade 2 are gradually deformed, meaning the thickness of the inclined steps gradually decreases from the middle of blade 2 to the edges on both sides. This is to use the sharp blade 2 to break up powdery clumps, thereby achieving a better centrifugation effect.

[0029] The opening of the guide arc surface 7 is perpendicular to the axis of the central tube 1 to better introduce the powder. This guides the powder, which could impact the blade 2, while preventing direct impact. Bolt fixing holes 8 are located on the central tube 1 to secure the guide device 4.

[0030] The centrifuge guide structure for peptide powder of this invention is used as follows:

[0031] A bolt fixing hole 8 is provided at the junction of the central tube 1 and the straight spiral section 10. The central tube 1 connects the guide device 4 to the central tube 1 through the bolt fixing hole 8 and the bolt 9. When the centrifuge is started, when the central tube 1 drives the guide device 4 to rotate, the powdery solid flows in from the guide arc surface 7, then passes through the feed port 6, and finally flows out from the guide channel 5. This process transforms the powdery solid that originally directly impacted the blade 2 into powder that enters at the same angle as the blade 2, reducing the impact on the blade 2. At the same time, if it is necessary to clean the residual solid powder, the bolt fixing hole 8 and the bolt 9 are disassembled, and the guide device is cleaned. This solution also avoids the accumulation of solid powder on the blade 2.

[0032] The length, curvature, and thickness of the lines on the guide arc surface 7 in the attached diagram are for illustrative purposes only, and those skilled in the art can make adaptive adjustments according to actual usage.

[0033] The length, thickness, size, and quantity of the lines of the guide device 4 and guide channel 5 in the attached drawings are for illustrative purposes only, and those skilled in the art can make adaptive adjustments according to actual usage.

[0034] Both bolt fixing holes 8 and bolts 9 are conventional settings in the prior art. Those skilled in the art can select appropriate devices or settings based on the above description to achieve "a bolt fixing hole 8 is provided at the junction of the central tube 1 and the straight spiral section 10, because the central tube 1 will guide the guide device 4 through the bolt fixing hole 8 and bolts 9".

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
