Description

Technical Field

[0001] The utility model relates to the technical field of concrete raw material bins, and specifically relates to a concrete raw material bin with a cooling and heat insulation structure. Background Technique

[0002] With the increasing demand for high-quality concrete in the construction industry, the efficient and stable operation of concrete mixing plants has become particularly important. In the hot summer environment, concrete raw materials (especially cement) are prone to accelerate water evaporation during storage due to high temperature, resulting in caking, which not only affects the quality of concrete but also increases production costs. In addition, high temperature may also accelerate the failure of some chemical admixtures, further affecting the performance of concrete.

[0003] The existing cooling methods for concrete raw material bins generally adopt the method of periodically spraying the surface of the bin body, aiming to take away heat through water evaporation to achieve the cooling purpose. However, this method exposes significant problems: First, the water resource consumption is huge. Since the spraying water stays on the surface of the bin body for a very short time, most of the water evaporates rapidly without fully contributing to cooling, resulting in a great waste of water resources. Second, the cooling effect is not stable. The immediate cooling effect brought by spraying is difficult to maintain for a long time. Once the spraying is interrupted, the temperature inside the bin will rise rapidly, making it difficult to ensure that the raw materials are in suitable storage conditions for a long time, thus affecting the quality and consistency of concrete products. Content of the Utility Model

[0004] The purpose of the utility model is to provide a concrete raw material bin with a cooling and heat insulation structure to solve the problems in the above background technique that the current spraying cooling method for concrete raw material bins has serious water resource waste, fails to fully play the cooling role due to too fast water evaporation, and the cooling effect is short-term and unstable, and it cannot continuously maintain a suitable storage temperature, thus affecting the quality of concrete.

A number of flow guide plates that fit with the outer wall of the outer shell are arranged around the outer wall of the raw material bin main body, and a conduit is connected between the top of each flow guide plate and the bottom of the rainwater collection box.

[0006] Preferably, a number of groups of partition blocks are evenly arranged in the gap between the outer shell and the inner shell, and the gel heat insulation plates are embedded in the space between each group of partition blocks.

[0007] Preferably, brackets are provided on both sides of the bottom of the rainwater collection box, fixing pins are inserted through the bottom ends of the brackets, and a fixing sleeve matching the structure of the fixing pins is provided at the top end of the diversion plate.

[0008] Preferably, a water collection cavity is provided inside the upper end of the diversion plate, the water collection cavity communicates with the connection parts of the conduit and the diversion plate, and a plurality of overflow channels are evenly provided at the bottom of the water collection cavity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: a concrete raw material bin with a cooling and heat insulation structure, including a raw material bin main body 1, which is a double-layer composite structure composed of an outer shell 2 and an inner shell 3. The outer shell 2 is preferably made of a metal material with strong weather resistance and ultraviolet resistance, such as aluminum alloy or galvanized steel plate treated with a special coating, to enhance its ability to resist external environmental erosion, while maintaining good heat reflection performance and effectively blocking the transfer of external heat inward. The inner shell 3 is made of food-grade or building material-grade stainless steel (such as SUS304), which is very suitable for storing environments that may come into contact with cement or other chemical additives due to its excellent corrosion resistance, wear resistance, and easy cleaning properties. A number of gel heat insulation plates 4 are arranged around the gap between the outer shell 2 and the inner shell 3, and a rainwater collection box 7 is provided at the top of the raw material bin main body 1. A number of guide plates 5 that fit closely to the outer wall of the outer shell 2 are arranged around the outer wall of the raw material bin main body 1. A conduit 6 is connected between the top of the guide plate 5 and the bottom of the rainwater collection box 7. The connection between the conduit 6 and the guide plate 5 is connected by a detachable threaded structure. The raw material bin main body 1 of this structure adopts an innovative double-layer composite structure, which is composed of a durable outer shell 2 and an inner shell 3 with anti-corrosion and anti-wear lining. High-efficiency gel heat insulation plates 4 are embedded between the two layers. This not only effectively prevents the penetration of external high temperature but also reduces the loss of internal cold, ensuring the temperature stability of the raw material bin main body 1. Moreover, the rainwater collection box 7 can be used for cooling the raw material bin main body 1 after the collected rainwater is purified, realizing the recycling of precious water resources and greatly saving water resources. In addition, the guide plates 5 installed around the outer wall of the raw material bin main body 1 are closely attached to the outer wall of the outer shell 2 and are connected to the rainwater collection box 7 through the conduit 6. They can not only guide the smooth flow of rainwater for cooling but also introduce external cooling water as needed, which is evenly distributed through the guide plates 5 to enhance the cooling effect. Thus, the cooling and heat insulation efficiency of the raw material bin main body 1 is significantly improved, ensuring the quality of raw materials, greatly promoting resource conservation, and demonstrating high economic efficiency and environmental protection. A number of groups of partition blocks 12 are evenly arranged in the gap between the outer shell 2 and the inner shell 3, and the gel heat insulation plates 4 are embedded in the space between each group of partition blocks 12. The partition blocks 12 of this structure can not only serve as a support frame for the gel heat insulation plates 4 but also enhance the structural stability of the entire raw material bin main body 1, preventing the gel heat insulation plates 4 from shifting or deforming due to gravity or external force, ensuring the heat insulation performance and structural safety under long-term use. Moreover, the partition blocks 12 make it more convenient to locally adjust or replace the gel heat insulation plates 4 in specific areas, improving the convenience and economy of maintenance. Brackets 9 are provided on both sides of the bottom of the rainwater collection box 7. The inner ends of the brackets 9 are welded and fixed to the outer wall of the outer shell 2, and the bottom end of the bracket 9 is inserted with a fixing pin 10 through a threaded structure. And a fixing sleeve 11 that matches the structure of the fixing pin 10 is provided at the top of the guide plate 5. The bracket 9 of this structure can quickly install the guide plate 5 by inserting the fixing pin 10 into the fixing sleeve 11 to achieve a reliable connection with the rainwater collection box 7.It also allows the angle of the guide plate 5 to be quickly adjusted or disassembled for maintenance when necessary, which improves the flexibility and practicality of the device. A water collecting chamber 51 is provided inside the upper end of the guide plate 5, and the water collecting chamber 51 is interconnected with the connection between the conduit 6 and the guide plate 5, and a plurality of overflow channels 52 are evenly provided at the bottom of the water collecting chamber 51. The guide plate 5 of this structure realizes the efficient collection and distribution of rainwater or externally introduced cooling water through the design of the water collecting chamber 51 and the overflow channel 52. The water collecting chamber 51 first gathers the water flowing into the inside of the guide plate 5, and then flows through a plurality of overflow channels 52 and evenly acts on the outer shell 2, ensuring the continuity and uniformity of the cooling process of the guide plate 5. The center of the bottom wall of the rainwater collection box 7 is welded and fixed to the outer wall at the top of the outer shell 2, and a filter screen 8 is installed inside the upper end of the rainwater collection box 7. The filter 8 can achieve the key step of preliminary purification, and can effectively intercept pollutants such as leaves, dust, and debris to prevent these impurities from entering the subsequent channels with rainwater, reducing the frequency of structural blockage and maintenance, and protecting the normal operation of the cooling structure. There are four guide plates 5, all of which are arc-shaped structures, and a number of heat sinks are evenly arranged on the outer wall of the guide plate 5. The arc-shaped structure of the guide plate 5 of this structure can increase the surface area in contact with the air, that is, when water flows through the guide plate 5, this shape promotes the uniform distribution of water flow and the natural convection of air, enhances the heat exchange efficiency, and helps to quickly dissipate heat. The heat sinks on the outer wall of the guide plate 5 further accelerate the process of water evaporation and heat dissipation, so that the water flow or rainwater guided by the guide plate 5 can more effectively take away the surrounding heat when evaporating, achieving a better cooling effect.

[0018] Working principle: When using the concrete raw material silo with a cooling and heat-insulating structure, first, when the raw material silo main body 1 is in use, the external high temperature is effectively reflected by the sturdy and weather-resistant outer shell 2 to reduce heat intrusion, and the inner shell 3 is made of stainless steel to ensure the cleanliness and durability of the internal storage environment, and the gel insulation board 4 embedded between the double-layer structure is supported by the spacer block 12 to stably isolate the heat and maintain a constant temperature in the silo. During the rainy season, rainwater flows into the interior of the rainwater collection box 7 and is filtered and purified through the filter net 8. Then the rainwater inside the rainwater collection box 7 is collected along the conduit 6 to the water collection chamber 51 inside the guide plate 5, and finally evenly distributed through the overflow channel 52 to evenly cool the outer shell 2. When the guide plate 5 is not needed, the fixing pin 10 on the bracket 9 can be turned out from the fixing sleeve 11 to facilitate the maintenance of the guide plate 5, thereby completing a series of work.

[0019] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
