Description

Technical Field

[0001] This utility model relates to the field of food processing and production equipment technology, and in particular to a syrup conveying device. Background Technology

[0002] In the food processing industry, syrup is a type of high-viscosity fluid food ingredient made from raw materials such as sucrose, fructose, and malt through processes such as dissolution and concentration. It is widely used in the production of beverages, candies, baked goods, dairy products, and other products. Its physical characteristics include high viscosity, temperature sensitivity, and the need to meet food-grade hygiene standards. Syrup conveying equipment is a specialized piece of equipment in food processing production lines used to ensure the stable transport of syrup from raw material storage tanks to processing steps. Its core function is to ensure continuous and leak-free transport of syrup while meeting food hygiene requirements, adapting to the different production stages' needs for syrup transport volume and flow rate.

[0003] Existing equipment for conveying syrup typically uses a circular cross-section conveying pipe as its core component. The inner wall of the pipe is a smooth, arc-shaped surface, and both ends are directly connected to the output of a rotor pump via end flanges. The insulation structure for the conveying pipe usually employs an integral cylindrical insulation layer, which is directly fitted around the outer circumference of the circular pipe. The general workflow is as follows: after starting the rotor pump, it pressurizes the syrup and sends it through the end flanges into the circular conveying pipe. The syrup flows along the inner wall of the circular pipe to achieve conveying. At the same time, the integral insulation layer wraps around the pipe, reducing heat exchange between the syrup inside the pipe and the external environment, thus preventing temperature fluctuations in the syrup.

[0004] This leads to several shortcomings: First, the flow velocity distribution at various points on the inner wall of the circular cross-section pipe is uneven. Due to the force of gravity, the syrup at the bottom of the pipe experiences greater pressure, resulting in a flow velocity much lower than that at the top. This causes impurities in the syrup to settle and accumulate at the bottom, requiring frequent pipe disassembly and cleaning, which affects production efficiency. Second, the insulation layer of the existing equipment is difficult to disassemble and assemble due to its overall structure. If a part is damaged, the entire layer needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0005] The present invention provides a syrup conveying device that can solve the problem of uneven flow velocity in the conveying pipeline leading to easy deposition of impurities in the existing syrup conveying devices.

[0006] A syrup conveying device includes a rotor pump with conveying pipes at both ends. Each end of the conveying pipe has an end flange, which is fixedly installed at the output end of the rotor pump. The conveying pipe has a combined cross-section, comprising a semi-circular arc surface and an inclined plane. The semi-circular arc surface is located at the upper part of the conveying pipe's cross-section, and the inclined plane is located at the lower part. The two ends of the semi-circular arc surface and the inclined plane are smoothly connected. A guide rib is also provided on the inner wall of the conveying pipe, extending axially along the conveying pipe. Both ends of the guide rib are fixedly installed on the inclined plane, with their top ends contacting the inner wall of the semi-circular arc surface.

[0007] Preferably, the guide ribs are provided in a plurality of form and are evenly distributed along the circumference of the conveying pipe.

[0008] Preferably, the cross-section of the guide rib is semi-circular.

[0009] Preferably, the inclined plane is inclined relative to the horizontal reference plane of the conveying pipe, and the inclined plane forms a longitudinal lowest ridge line along the axial direction of the conveying pipe.

[0010] Preferably, the center of the semi-circular arc surface is located on the axial centerline of the conveying pipeline.

[0011] Preferably, the outer periphery of the conveying pipeline is provided with a heat insulation layer, the heat insulation layer is provided in a plurality of parts and is cylindrical in shape, and the heat insulation layer extends along the axis of the conveying pipeline.

[0012] Preferably, a thermally conductive patch is provided inside the insulation layer, and the thermally conductive patch is fixedly installed on the inner wall of the insulation layer.

[0013] Preferably, the insulation layers are provided with connecting components and are connected to each other through the connecting components, and the connecting components are located at the side ends of the insulation layers.

[0014] Preferably, the connecting component includes a card block and a card slot; The card block is fixedly installed at one end of the insulation layer, and the card slot is opened at the other end of the insulation layer. The size of the card block and the card slot are adapted to each other.

[0015] Preferably, a locking block is fixedly installed on the side of the insulation layer near the rotor pump, and a locking groove is opened on the side of the end flange near the insulation layer, and the locking block is embedded in the locking groove.

[0016] The beneficial effects of this utility model are as follows: By smoothly connecting the semi-circular arc surface and the inclined plane within the cross-section of the conveying pipe, and extending the guide ribs along the pipe axis, and with several guide ribs evenly distributed around the pipe circumference and having a semi-circular cross-section, the flow field within the conveying pipe is precisely optimized. The semi-circular arc surface ensures an effective conveying diameter at the top to stabilize the top flow velocity, while the inclined angle of the inclined plane guides impurities to converge towards the lowest longitudinal ridge. Furthermore, the flow regulation effect of the guide ribs ensures uniform syrup flow velocity at all circumferential positions within the pipe, significantly reducing the risk of bottom impurity deposition during syrup conveying, ensuring smooth syrup conveying without affecting syrup quality. In addition, by using segmented cylindrical insulation layers fitted around the outer circumference of the conveying pipe and arranged sequentially along the pipe axis, with adjacent insulation layers tightly connected by a locking block embedded in a slot connection component, the segmented insulation layers prevent syrup crystallization due to temperature fluctuations, and the connection component prevents insulation layer misalignment. The segmented design also facilitates local replacement and maintenance of the insulation layers. Attached Figure Description

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1 to 5As shown in the figure, a syrup conveying device provided by this utility model includes a rotor pump 1. Both ends of the rotor pump 1 are provided with conveying pipes 2. Both ends of the conveying pipes 2 are respectively provided with end flanges 3. The conveying pipes 2 are fixedly installed at the output end of the rotor pump 1 through the end flanges 3. The cross-section of the conveying pipes 2 is a combined structure, which includes a semi-circular arc surface 4 and an inclined plane 5. The semi-circular arc surface 4 is located at the upper part of the cross-section of the conveying pipes 2, and the inclined plane 5 is located at the lower part of the cross-section of the conveying pipes 2. The two ends of the semi-circular arc surface 4 and the inclined plane 5 are smoothly connected. The inner wall of the conveying pipes 2 is also provided with guide ribs 6. The guide ribs 6 extend along the axial direction of the conveying pipes 2. The two ends of the guide ribs 6 are fixedly installed on the inclined plane 5, and their top ends are in contact with the inner wall of the semi-circular arc surface 4.

[0021] The conveying pipe 2 is rigidly fixed to the output end of the rotor pump 1 via the end flange 3, ensuring the sealing and stability of the syrup during conveying. The semi-circular arc surface 4 and the inclined plane 5 are smoothly connected within the cross-section of the conveying pipe 2. The guide rib 6 extends axially and is fixed at both ends to the inclined plane 5, with the top end fitting against the inner wall of the semi-circular arc surface 4, forming a complete internal flow channel structure. The flow velocity distribution on the inner wall of the traditional circular conveying pipe 2 is uneven, and the low flow velocity at the bottom can easily lead to the deposition of impurities in the syrup. The semi-circular arc surface 4 can ensure an effective conveying diameter at the top, and the inclined plane 5 can specifically optimize the flow field at the bottom. With the guide rib 6, the flow pattern can be further regulated, allowing the flow velocity distribution of the syrup in the conveying pipe 2 to be more uniform, reducing the risk of impurity deposition at the bottom, while avoiding the formation of turbulence due to excessive flow velocity at the top, ensuring the smoothness of syrup conveying without damaging the syrup's own structure.

[0022] The guide ribs 6 are provided in several parts and are evenly distributed along the circumference of the conveying pipe 2.

[0023] Several guide ribs 6 are evenly arranged circumferentially on the inner wall of the conveying pipe 2. The spacing between adjacent guide ribs 6 is consistent, and each guide rib 6 maintains axial extension and is stably connected to the inclined plane 5 and the semi-circular arc surface 4. If the number of guide ribs 6 is too small or the distribution is uneven, it will cause local flow field disturbance in the pipe and make it impossible to fully optimize the flow velocity. Syrup at different circumferential positions in the conveying pipe 2 can be guided, the flow state is more stable, and local areas will avoid low flow velocity or eddies due to lack of guidance, further reducing the possibility of impurity deposition.

[0024] The cross-section of the guide rib 6 is semi-circular.

[0025] The cross-sectional profile of the guide rib 6 is semi-circular, with its arc-shaped surface facing the center flow channel of the conveying pipe 2. Its flat side is fixedly connected to the inner wall of the conveying pipe 2, with no sharp edges or corners exposed. If the guide rib 6 has sharp edges or corners, it may scratch the molecular structure in the syrup. The semi-circular cross-section design allows the syrup to flow smoothly through the guide rib 6 without any residual dead corners, while avoiding damage to the syrup molecules and ensuring that the quality of the syrup is not affected by the conveying process.

[0026] The inclined plane 5 is inclined relative to the horizontal reference plane of the conveying pipe 2, and the inclined plane 5 forms a longitudinal lowest ridge line along the axial direction of the conveying pipe 2.

[0027] The inclined plane 5 is inclined with reference to the horizontal reference plane on which the conveying pipe 2 is placed. Its two ends are smoothly connected to the bottom of the semi-circular arc surface 4. Due to the overall inclination, a continuous longitudinal lowest ridge line is naturally formed along the axial direction of the conveying pipe 2. The reason for designing the inclined plane 5 to be inclined and forming the longitudinal lowest ridge line is that the traditional conveying pipe 2 is often placed in a horizontal state, which cannot guide impurities. Impurities are easy to disperse and deposit in the entire bottom area, making it difficult to concentrate and process them. This design allows impurities in the syrup to gather along the inclined plane 5 to the longitudinal lowest ridge line under the action of gravity, avoiding the dispersion and deposition of impurities. Subsequently, the area near the ridge line can be cleaned in a targeted manner, improving the convenience of cleaning.

[0028] The center of the semi-circular arc surface 4 is located on the axial center line of the conveying pipeline 2.

[0029] The center of the semicircular arc surface 4 is completely coincident with the axial centerline of the conveying pipe 2, ensuring that the semicircular arc surface 4 is symmetrically distributed on the upper part of the cross-section of the conveying pipe 2. If the center of the semicircular arc surface 4 is offset, it will cause asymmetry on both sides of the semicircular arc surface 4, resulting in uneven flow velocity of the syrup at the top and easy formation of local turbulence. This design allows the syrup at the top of the conveying pipe 2 to flow along the symmetrical arc surface, with a consistent flow velocity at each point, avoiding energy waste and syrup structure damage caused by turbulence, and ensuring the stability of the top conveying.

[0030] The outer periphery of the conveying pipeline 2 is covered with a heat insulation layer 7. The heat insulation layer 7 is provided in several parts and is cylindrical in shape. The heat insulation layer 7 extends along the axis of the conveying pipeline 2.

[0031] Several cylindrical insulation layers 7 are respectively fitted onto the outer circumferential wall of the conveying pipe 2. Each insulation layer 7 is arranged sequentially along the axial direction of the conveying pipe 2, and the entire outer circumference of the conveying pipe 2 is covered. If an integral insulation layer 7 is used, it is inconvenient to disassemble and assemble during use, and the whole layer needs to be replaced when there is partial damage. However, the segmented insulation layer 7 can be flexibly maintained. This can provide all-round insulation for the conveying pipe 2, reduce the heat exchange between the syrup in the pipe and the external environment, and prevent the syrup from crystallizing due to temperature fluctuations. At the same time, the segmented setting facilitates the subsequent partial replacement or repair of the insulation layer 7, reducing maintenance costs.

[0032] The insulation layer 7 is provided with a thermal conductive patch 71, which is fixedly installed on the inner wall of the insulation layer 7.

[0033] The heat-conducting patch 71 has a sheet-like structure. One side of it is tightly fixed to the inner wall of the insulation layer 7, and the other side is attached to the outer peripheral wall of the delivery pipe 2, filling the tiny gap between the insulation layer 7 and the delivery pipe 2. Tiny gaps can easily form between the insulation layer 7 and the outer peripheral wall of the delivery pipe 2 due to assembly. Air in the gaps will reduce the insulation effect. By filling the gaps with the heat-conducting patch 71, the heat loss caused by air insulation is reduced, the heat transfer stability between the insulation layer 7 and the delivery pipe 2 is improved, the temperature of the syrup in the pipe is more uniform, and the risk of crystallization is further reduced.

[0034] The insulation layers 7 are provided with connecting components 8 and are connected to each other through the connecting components 8. The connecting components 8 are located at the side ends of the insulation layers 7.

[0035] The connecting components 8 are fixed to the opposite side ends of two adjacent insulation layers 7 respectively. The cooperation of the connecting components 8 makes the adjacent insulation layers 7 tightly connected. If the segmented insulation layers 7 do not have a connecting structure, they are prone to misalignment or gaps during use, causing heat to be lost through the gaps. This can fix the relative position of the adjacent insulation layers 7, avoid misalignment or gaps, ensure the overall sealing of the insulation layers 7, and improve the overall insulation effect.

[0036] The connecting component 8 includes a card block 81 and a card slot 82; The card block 81 is fixedly installed at one end of the insulation layer 7, and the card slot 82 is opened at the other end of the insulation layer 7. The card block 81 and the card slot 82 are adapted to each other in size.

[0037] The locking block 81 is a raised structure, integrated with one end of the insulation layer 7. The slot 82 is a recessed structure, opened on the other end of the same insulation layer 7. The shape and size of the locking block 81 are perfectly matched with the slot 82. Adjacent insulation layers 7 can be connected by the locking block 81 being inserted into the slot 82. This enables quick assembly and disassembly of the insulation layers 7 without the need for additional tools, improving the efficiency of maintenance or replacement of the insulation layers 7. At the same time, the locking fit ensures the tight connection of adjacent insulation layers 7, preventing heat leakage.

[0038] On the side of the insulation layer 7 near the rotor pump 1, a locking block 81 is fixedly installed. On the side of the end flange 3 near the insulation layer 7, a locking groove 82 is provided, and the locking block 81 is embedded in the locking groove 82.

[0039] The insulation layer 7 near the rotor pump 1 has a locking block 81 fixed to its side facing the rotor pump 1, and the end flange 3 has a corresponding locking groove 82 on its side facing the insulation layer 7. The locking block 81 is completely embedded in the locking groove 82, so that the insulation layer 7 and the end flange 3 are tightly connected. Because the area near the rotor pump 1 is prone to gaps between the insulation layer 7 and the end flange 3 due to equipment vibration, heat is easily lost through the gaps. This can fix the position of the insulation layer 7 near the rotor pump 1, avoid gaps caused by vibration, reduce heat loss from the connection between the insulation layer 7 and the end flange 3, ensure the temperature stability of the area of ​​the conveying pipeline 2 near the rotor pump 1, and further prevent syrup crystallization.

[0040] In summary, the syrup conveying device provided by this utility model embodiment operates as follows: First, the rotor pump 1 is started. After the syrup enters the conveying pipe 2, it first contacts the combined cross-section flow channel formed by the semi-circular arc surface 4 and the inclined plane 5. The semi-circular arc surface 4 forms a symmetrical top flow channel, allowing the syrup at the top to flow evenly along the arc surface. Under the action of gravity, the inclined plane 5 guides impurities in the syrup to converge towards the lowest longitudinal ridge formed by its axial direction, preventing impurities from dispersing and depositing at the bottom of the pipe. At the same time, several guide vanes evenly distributed circumferentially along the inner wall of the conveying pipe 2... The rib 6 further divides the flow field inside the pipeline into uniform sub-channels, forcibly regulates the flow state, and ensures that the syrup flow rate is consistent in all areas of the pipeline. During the syrup transportation process, the segmented cylindrical insulation layer 7 on the outer periphery of the transportation pipeline 2 plays a role simultaneously. Each insulation layer 7 is tightly connected by the connecting component 8 at the side end, and the insulation layer 7 near the rotor pump 1 is fixed to the end flange 3 by the clamping block 81 and the clamping groove 82. At the same time, the heat-conducting patch 71 on the inner wall of the insulation layer 7 fills the tiny gap between the insulation layer 7 and the outer wall of the transportation pipeline 2, ensuring that the syrup quality is not affected by the transportation process.

[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
