Description
Technical Field
[0001] This utility model relates to the field of auger heating technology, specifically an energy-saving preheating auger. Background Technology
[0002] A screw conveyor is a machine that uses a motor to drive a screw to rotate, thus pushing materials to achieve the purpose of conveying. It can convey horizontally, inclined, or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation.
[0003] Preheating augers, as a device that combines the preheating and transportation of powdered and granular materials, are widely used in the food, feed, and brewing industries. However, existing preheating equipment suffers from problems such as excessively long preheating times and poor preheating effects.
[0004] Based on this, an energy-saving preheating auger is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
[0005] The purpose of this invention is to provide an energy-saving preheating auger to solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An energy-saving preheating auger includes a transport tank and a water storage tank. The water storage tank is fitted with an outer shell. A drive motor is installed on the side wall of the transport tank. The output shaft of the drive motor is connected to an auger shaft for transporting materials via a coupling. A steam delivery pipe is connected to the top of the water storage tank. The other end of the steam delivery pipe extends into the interior of the outer shell. A steam return pipe is also connected to the interior of the outer shell. The other end of the steam return pipe is connected to the interior of the water storage tank.
[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:
[0009] In one alternative: a high-temperature water pump is installed on one side of the water storage tank. The input end of the high-temperature water pump is connected to the inside of the water storage tank through a pipe, and the output end of the high-temperature water pump is connected to a water delivery pipe. One end of the water delivery pipe passes through the outer shell and is connected to the inside of the water storage tank.
[0010] In one alternative: the water pipe is spirally wound around the outer wall of the transport tank.
[0011] In one alternative: the interior of the outer shell is connected to a condensate return pipe, and the other end of the condensate return pipe is connected to the interior of the water storage tank.
[0012] In one alternative: a one-way valve is installed inside the condensate return pipe.
[0013] In one alternative: the water storage tank is equipped with multiple heating rods inside.
[0014] In one alternative: the outer shell is provided with an insulation layer.
[0015] In one alternative: the interior of the transport tank is connected to an inlet pipe for feeding and an outlet pipe for discharging.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model uses steam generated by the heating rod inside the water storage tank to enter the outer shell through the steam delivery pipe, thereby heating the entire transport tank. Excess steam is circulated through the steam return pipe. At the same time, a high-temperature water pump drives hot water to flow along the spiral water delivery pipe wrapped around the outer wall of the transport tank. The spiral structure increases the contact area between the hot water and the transport tank. The combination of dual heating ensures that the auger shaft and materials inside the transport tank are heated more comprehensively and evenly, effectively solving the problems of excessively long preheating time and insufficient preheating effect of existing preheating equipment, and greatly improving preheating efficiency and quality.
[0018] 2. This utility model reduces internal heat loss and energy consumption through the external insulation layer of the outer shell. Furthermore, the hot water circulates between the high-temperature water pump, water pipes, and storage tank, achieving efficient recycling of energy and water resources, significantly improving the energy-saving performance of the equipment and reducing operating costs.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] In one embodiment, such as Figures 1-5 As shown, an energy-saving preheating auger includes a transport tank 1 and a water storage tank 4. The water storage tank 4 is fitted with an outer shell 2. A drive motor 5 is installed on the side wall of the transport tank 1. The output shaft of the drive motor 5 is connected to an auger shaft for transporting materials via a coupling. A steam conveying pipe 11 is connected to the top of the water storage tank 4. The other end of the steam conveying pipe 11 extends into the interior of the outer shell 2. A steam return pipe 9 is also connected to the interior of the outer shell 2. The other end of the steam return pipe 9 is connected to the interior of the water storage tank 4.
[0027] In this embodiment, the steam generated in the water storage tank 4 enters the interior of the outer shell 2 through the steam delivery pipe 11 to heat the transport tank 1. The steam in the outer shell 2 flows back to the water storage tank 4 through the steam return pipe 9 to realize steam recycling. The drive motor 5 drives the auger shaft to rotate through the coupling to complete the material transportation.
[0028] In one embodiment, such as Figure 4 As shown, a high-temperature water pump 8 is installed on one side of the water storage tank 4. The input end of the high-temperature water pump 8 is connected to the inside of the water storage tank 4 through a pipe. The output end of the high-temperature water pump 8 is connected to a water delivery pipe 10. One end of the water delivery pipe 10 passes through the outer shell 2 and is connected to the inside of the water storage tank 4.
[0029] The high-temperature water pump 8 extracts the hot water from the water storage tank 4, which is then transported back to the water storage tank 4 via the water pipe 10, forming a hot water circulation. The hot water flow then provides additional heating to the auger shaft inside the transport tank 1.
[0030] In one embodiment, such as Figure 4 As shown, the water pipe 10 is spirally wound around the outer wall of the transport tank 1;
[0031] The water pipe 10, which is spirally wound around the outer wall of the transport tank 1, increases the contact area with the transport tank 1, improves the heating efficiency of hot water to the auger shaft inside the transport tank 1, and makes the heating more uniform.
[0032] In one embodiment, such as Figure 5 As shown, the interior of the outer shell 2 is connected to a condensate return pipe 12, and the other end of the condensate return pipe 12 is connected to the interior of the water storage tank 4.
[0033] The condensate formed by the condensation of steam inside the outer shell 2 flows back to the water storage tank 4 through the condensate return pipe 12, realizing the recycling and reuse of condensate and reducing water waste.
[0034] In one embodiment, such as Figure 5 As shown, a one-way valve 13 is installed inside the condensate return pipe 12;
[0035] A one-way valve 13 is installed inside the condensate return pipe 12 to prevent hot water in the water storage tank 4 from flowing back into the condensate return pipe 12 and to ensure that the condensate return channel is unobstructed.
[0036] In one embodiment, such as Figure 5 As shown, the water storage tank 4 is equipped with multiple heating rods 14 inside;
[0037] Multiple heating rods 14 inside the water storage tank 4 generate heat after being powered on, heating the water in the water storage tank 4 and providing a heat source for steam generation and hot water circulation.
[0038] In one embodiment, such as Figure 1 As shown, an insulation layer 3 is provided on the outside of the outer casing 2;
[0039] The insulation layer 3 on the outside of the outer shell 2 reduces heat loss from the inside of the outer shell 2, reduces energy loss, and maintains the temperature stability of the heating environment.
[0040] In one embodiment, such as Figure 1 and Figure 4 As shown, the inside of the transport tank 1 is connected to a feed pipe 6 for feeding and a discharge pipe 7 for discharging.
[0041] The material enters the transport tank 1 through the feed pipe 6, and after being heated and conveyed by the auger shaft, it is discharged from the discharge pipe 7, completing the material feeding, heating and discharging process.
[0042] The above embodiment discloses an energy-saving preheating auger, wherein the heating rod 14 heats the water in the water storage tank 4, and the generated steam enters the outer shell 2 through the steam delivery pipe 11 to heat the auger shaft inside the transport tank 1. Excess steam flows back through the steam return pipe 9. The high-temperature water pump 8 drives the hot water in the water storage tank 4 to circulate along the spiral water delivery pipe 10, further heating the auger shaft inside the transport tank 1 and improving the heating uniformity. The condensate formed by the condensation of steam in the outer shell 2 flows back to the water storage tank 4 through the condensate return pipe 12 with a one-way valve 13. The heat insulation layer 3 on the outside of the outer shell 2 reduces heat loss. The drive motor 5 drives the auger shaft to rotate, and the material enters the transport tank 1 from the feed pipe 6. After being heated, it is discharged from the discharge pipe 7, realizing material transportation and efficient energy-saving preheating. When working for a long time, water can be replenished inside the water storage tank 4.
[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
