Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and in particular to a concrete production feeding device. Background Technology

[0002] Concrete delivery systems are indispensable equipment in modern construction. Their main function is to efficiently and accurately transport concrete from the mixing plant or transport vehicle to the pouring point. Through pipeline pumping or mechanical conveying, these systems significantly improve concrete delivery efficiency, avoiding problems such as material segregation and time delays caused by traditional manual handling. At the same time, they reduce labor intensity and construction safety risks. Their application not only ensures the continuity and uniformity of concrete pouring in large-scale projects, but also adapts to complex working environments such as high-rise buildings and underground structures. They are of key significance for improving project quality and shortening the construction period, and represent an important manifestation of the development of industrialized construction technology.

[0003] The quality of concrete during transportation directly affects the final construction quality. However, traditional feeding equipment does not perform well in this regard. Concrete is a complex mixture of sand, gravel, cement slurry, and other materials. During transportation, the concrete generates heat due to prolonged friction with the inner wall of the conveying pipe. The increased temperature causes the cement to solidify faster, resulting in increasingly dry concrete with reduced fluidity, making it difficult to pump and pour. If the concrete segregates or becomes too dry, it will cause significant problems in the pouring process. For example, it will be difficult to vibrate the concrete firmly, and small holes or honeycomb-like voids may appear in the poured concrete structure. As a result, the strength and durability of the concrete structure will be greatly reduced. Therefore, a concrete production and feeding device is needed. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a concrete production feeding device that can solve the problems of concrete raw materials deteriorating in performance and affecting construction quality due to excessive temperature during transportation, as well as the poor effect and low efficiency of traditional cooling methods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete production feeding device, comprising a conveying pipe and a cooling mechanism during the conveying process. The cooling mechanism during the conveying process includes a coolant storage tank, a cooling pipe, heat dissipation fins, a water pump, and a connecting pipe. The cooling pipe is fixedly connected to the outer surface of the conveying pipe and is spirally wound. Multiple heat dissipation fins are equidistantly fixedly connected to the surface of the conveying pipe in a linear array. The connecting pipe is fixedly connected to both ends of the cooling pipe.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a concrete production feeding device, wherein: The outer surface of the conveying pipe 1 is fixedly connected to the cooling pipe 11, which is spirally wound. The two are connected by welding or clamping. The spiral shape can increase the contact area and improve the heat exchange efficiency.

[0021] The cooling pipe 11 is fixedly connected to the connecting pipe 14 at both ends. The connecting pipe 14 is fixedly connected to the water pump 13. The water pump 13 is fixedly connected to the coolant storage tank 8, forming a closed coolant circulation path. The use of corrosion-resistant pipes can extend their service life.

[0022] The surface of the delivery pipe 1 is linearly arrayed with multiple heat dissipation fins 12 fixedly connected at equal intervals. Aluminum alloy material can be used to enhance thermal conductivity. In combination with the cooling pipe 11, the overall heat dissipation area is increased and heat dissipation is accelerated.

[0023] The bottom of the delivery pipe 1 is fixedly connected to the air guide shroud 4. Multiple cooling fans 15 are fixedly connected in a linear array at equal intervals on the surface of the air guide shroud 4. The top of the air guide shroud 4 is provided with an opening to guide the airflow direction. The cooling fans 15 accelerate the airflow and work with the heat dissipation fins 12 to improve the air cooling effect.

[0024] The bottom of the air guide 4 is fixedly connected to the heat dissipation base 5, and the bottom of the heat dissipation base 5 is fixedly connected to the device base plate 6. A gap for air circulation is left between the air guide 4 and the heat dissipation base 5. The width of the gap can be adjusted according to the heat dissipation requirements to ensure smooth air circulation and enhance the heat dissipation effect.

[0025] The top of the device base plate 6 is fixedly connected to the bracket 7. The top of the bracket 7 is fixedly connected to the conveying pipe 1. The bracket 7 can be made of steel structure to enhance the load-bearing capacity. Together with the flow guide shroud 4 and the heat dissipation base 5, it can stably support the conveying pipe 1 and ensure the structural stability of the device during operation.

[0026] The coolant storage tank 8 has an inlet pipe 9 and an outlet pipe 10 fixedly connected to its surface. The bottom of the coolant storage tank 8 is fixedly connected to the base plate 6 of the device. Valves can be installed on the inlet pipe 9 and the outlet pipe 10 to control the flow rate, which facilitates the replenishment and replacement of coolant and ensures the continuous and effective operation of the cooling system.

[0027] Motor 2 is fixedly connected to the surface of conveying pipe 1. The output end of motor 2 extends into the inside of conveying pipe 1 and is fixedly connected to the conveying auger. The power of motor 2 can be selected according to the conveying volume. Motor 2 drives the conveying auger to rotate to realize concrete conveying, ensuring stable and efficient conveying process.

[0028] The top of the conveying pipe 1 is fixedly connected to the feed hopper 3. The feed hopper 3 can be funnel-shaped to facilitate the entry of raw materials. It works in conjunction with the conveying pipe 1 and the conveying auger to ensure that the concrete raw materials enter smoothly and are conveyed, thereby improving the feeding efficiency.

[0029] Working principle: Concrete raw materials enter the conveying pipe 1 from the feed hopper 3. The motor 2 starts and drives the conveying auger connected to its output end to rotate, thereby pushing the concrete raw materials to move within the conveying pipe 1 to achieve conveying. During the conveying process, in order to prevent the concrete from being affected by excessive temperature, the cooling mechanism starts to work. The water pump 13 draws out the coolant from the coolant storage tank 8 and conveys it through the connecting pipe 14 to the cooling pipe 11, which is fixed in a spiral shape on the outer surface of the conveying pipe 1. When the coolant flows in the cooling pipe 11, it absorbs the heat transferred by the conveying pipe 1, and then flows back through the connecting pipe 14. Meanwhile, multiple heat dissipation fins 12, which are linearly arrayed and equidistantly fixed on the surface of the delivery pipe 1, increase the heat dissipation area and accelerate heat dissipation. In addition, the cooling fan 15 at the bottom of the guide shroud 4 is started, and external air enters from the air inlet of the cooling fan 15. The air flows inside the guide shroud 4 and carries away the heat from the heat dissipation fins 12 and the cooling pipe 11, further improving the cooling effect. The delivery pipe 1 is fixed to the device base plate 6 by the bracket 7, the guide shroud 4, and the heat dissipation base 5 to ensure the stability of the overall structure. The coolant storage tank 8 can be replenished and replaced with coolant through the inlet pipe 9 and the outlet pipe 10.

[0030] Example 1: Cooling pipe 11 can be replaced with a corrugated pipe. The corrugated pipe is still fixed to the outer surface of the conveying pipe 1 in a spiral winding shape, which can enhance the fit with the conveying pipe 1 and improve the heat dissipation effect. Connecting pipe 14 can be replaced with a rubber hose. The rubber hose has better flexibility and is convenient for adjusting the layout of the device.

[0031] The heat dissipation fins 12 can be replaced with a heat dissipation mesh, which is fixed in a ring array on the surface of the delivery pipe 1. This can also increase the heat dissipation area and make the device lighter, thus reducing the load on the device.

[0032] The cooling fan 15 can be replaced with a vortex fan. The vortex fan is installed on the surface of the air guide 4, which provides stronger airflow and can accelerate the airflow speed inside the air guide 4, thereby improving the air cooling efficiency.

[0033] The support 7 can be replaced with a hydraulic support. The top of the hydraulic support is fixedly connected to the conveying pipe 1, and the bottom is fixedly connected to the base plate 6 of the device. The height of the conveying pipe 1 can be flexibly adjusted to adapt to different production scenarios.

[0034] Example 2: In addition to guiding the airflow to the heat dissipation fins 12 and the cooling pipe 11, the air guide 4 can also prevent external debris from contacting the delivery pipe 1, thus playing a protective role and preventing debris from affecting the heat dissipation effect and the normal operation of the delivery pipe 1.

[0035] The coolant storage tank 8 is not only used to store coolant, but also serves as a temporary coolant heat dissipation container, allowing the high-temperature coolant returning to cool down initially in the tank before being pumped to the cooling pipe 11 by the water pump 13, thereby improving cooling efficiency.

[0036] In addition to supporting the entire device, the base plate 6 can also have mounting holes on its surface to facilitate fixing the device to the ground or other equipment, thereby enhancing the stability of the device during operation and preventing shaking.

[0037] In addition to conveying concrete raw materials, the inner wall of the conveying pipe 1 can be treated with wear-resistant material to withstand the friction of the concrete raw materials, extend the service life of the conveying pipe 1 and reduce maintenance costs.

[0038] Example 3: When using this device in a high-temperature environment, the water pump 13 and all the cooling fans 15 can be turned on at the same time to increase the circulation speed and air volume of the coolant, enhance the cooling effect, and prevent the concrete from heating up rapidly due to the high ambient temperature.

[0039] When used in low-temperature environments, the cooling fan 15 can be turned off, and only the water pump 13 can be turned on and the coolant circulation speed reduced to avoid the concrete temperature being too low and affecting its performance, thus ensuring the normal delivery and use of the concrete.

[0040] In small-batch concrete conveying scenarios, the power of motor 2 can be reduced, the speed of the conveying auger can be decreased, and the power of water pump 13 can be appropriately reduced to save energy consumption and reduce production costs.

[0041] In scenarios involving continuous conveying of large quantities of concrete, it is necessary to ensure that motor 2 operates at full power while ensuring that the cooling mechanism works at full load to promptly remove the heat generated by the large amount of concrete conveying, maintain the stability of the concrete, and ensure the continuity of production.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
