Description

Technical Field

[0001] The present application relates to the technical field of concrete tank trucks, and in particular to a cooling device for concrete tank trucks. Background Art

[0002] At present, the concrete used in construction projects is usually transported to the construction site by concrete tank trucks after being configured in a mixing station. During transportation during the day in summer, the temperature of the tank can rise to more than 50°C under the sun. The concrete in the tank loses a lot of slump due to its own hydration heat release and the temperature rise of the tank due to exposure to the sun. For this reason, people have designed some devices that can cool the tank by spraying water on it. For example, a concrete mixer truck spray cooling system disclosed in Chinese patent application number 202121583399.2 includes a water tank, a spraying device, and a temperature control device. The system mainly sprays the tank with a water mist nozzle to moisten its surface and then lowers the temperature by evaporation. In actual use, when the vehicle is moving, the speed is fast, which will generate airflow, so that the water sprayed by the water mist nozzle will be blown away before falling on the surface of the tank, resulting in poor wetting effect, and the water mist nozzle consumes water quickly. The water storage on the tank truck is limited, which is not conducive to long-distance transportation. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a cooling device for a concrete tank truck, which passes cooling water into the drum and uses the rotation of the tank body to brush the cooling water on the tank body, thereby achieving the purpose of cooling by evaporation, saving water, and the water on the drum is not easily blown away by the airflow, so the tank body can be cooled normally during driving.

[0004] This application is implemented through the following technical solutions:

[0005] The present application proposes a cooling device for a concrete tank truck, comprising: a concrete tank truck, a support pipe, a roller, and a support frame.

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0019] In addition, the descriptions of "first", "second", etc. in this application are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0020] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides a cooling device for a concrete tank truck, comprising: a concrete tank truck 1, a support pipe 2, a roller 3, and a support frame 4. The concrete tank truck 1 is provided with a tank body 5, the support pipe 2 is installed on the upper part of the tank body 5 along the long direction of the tank body 5, and both ends of the support pipe 2 are fixedly connected to the concrete tank truck 1; there are multiple rollers 3, and the rollers 3 are sleeved on the outside of the support pipe 2 at intervals, and the outer periphery of the roller 3 is close to the outer periphery of the tank body 5; the support frame 4 spans across both sides of the tank body 5, and the lower part of the support frame 4 is fixedly connected to the concrete tank truck 1, and the upper part of the support frame 4 is fixedly connected to the support pipe 2.

[0021] After the concrete tank truck 1 is loaded with concrete, cooling water is added to the water tank 6 at the same time. Before the vehicle sets off, the valves 10 on the water supply pipe 7 and the air pipe 8 are opened. At this time, the high-pressure gas in the air tank 9 on the concrete tank truck 1 enters the water tank 6, and the water tank 6 is squeezed into the support pipe 2 through the water supply pipe 7 by air pressure. Since the support pipe 2 is provided with a water outlet 16, the cooling water passes through the water outlet 16, flows through the inner cylinder 11 and the outer cylinder 12 in sequence through the through hole, and then flows into the fabric layer 14 to wet the fabric layer 14. When the tank body 5 rotates, the roller 3 is driven to rotate by friction, so that the water on the fabric layer 14 is evenly brushed on the surface of the tank body 5. When the vehicle starts, the airflow will accelerate the evaporation of water, and the water can take away heat when evaporating, thereby reducing the temperature of the tank body 5 and ensuring the quality of the concrete in the tank body 5. Compared with the spraying method, the method of brushing cooling water consumes water at a lower rate and does not require a large water tank. In addition, when the vehicle is moving, the water on the drum 3 is not easily blown away by the airflow, and the tank body can also be cooled normally during driving to ensure the cooling effect.

[0022] Specifically, it also includes a water tank 6, the lower part of which is connected to the support pipe 2 through a water supply pipe 7, and the upper part of which is connected to the air tank 9 on the concrete tank truck 1 through an air pipe 8. The air tank 9 is an air brake air tank on the truck, and the cooling water is squeezed from the water tank 6 into the support pipe 2 through the compressed air in the air tank 9, so that the water in the water tank 6 can flow upward to supply water to the drum 3. Trucks are usually equipped with multiple air tanks 9, which are equipped with air pressure detection devices. When the pressure in the air tank 9 is low, an alarm can be sounded to ensure the operation of the brakes, and when the vehicle is running, compressed air will be continuously fed into the tank, so that part of the compressed gas is introduced from the air tank 9 into the water tank 6, which will not affect the safety of the vehicle.

[0023] In a specific embodiment, valves 10 are provided on the water supply pipe 7 and the air pipe 8 to control the on-off of the water supply pipe 7 and the air pipe 8, to add water, and to adjust the water outlet speed.

[0024] In a specific embodiment, Figure 2 As shown, the drum 3 includes an inner cylinder 11, an outer cylinder 12, and a fabric layer 14. The outer cylinder 12 is coaxial with the inner cylinder 11, and a plurality of spokes 15 are provided between the outer cylinder 12 and the inner cylinder 11. The inner cylinder 11 is sleeved on the support tube 2, and the fabric layer 14 is installed on the outer periphery of the outer cylinder 12. Through holes are provided on the inner cylinder 11 and the outer cylinder 12, and a water outlet 16 is provided at a corresponding position of the support tube 2. The fabric layer 14 is close to the outer periphery of the tank body 5. After the cooling water enters between the inner cylinder 11 and the outer cylinder 12 from the water outlet 16, the cooling water passes through the through hole and enters the inner side of the fabric layer 14 under the action of the centrifugal force of the outer cylinder 12, and continuously wets the fabric layer 14. After the tank body 5 rotates, the wet fabric layer 14 is used to apply water to the outer periphery of the tank body 5, so as to take away the heat on the tank body 5 by utilizing the principle of heat absorption by water evaporation, thereby achieving the purpose of cooling. The fabric layer 14 can absorb more water to ensure the effect of wetting the tank body 5.

[0025] Preferably, limiting rings 17 are provided at both ends of the inner cylinder 11, and the limiting rings 17 are fixedly mounted on the support tube 2 to ensure that the drum 3 rotates within a specified range.

[0026] In a preferred embodiment, the inner cylinder 11 is made of ultra-high molecular weight polyethylene, which has high wear resistance and self-lubricating properties, and can reduce the friction between the inner cylinder 11 and the support tube 2, so that the roller 3 can rotate smoothly on the support tube 2.

[0027] In a preferred embodiment, the diameters of the water outlet holes 16 gradually increase from bottom to top, so as to ensure that the water outlet speeds of the water outlet holes 16 on the support tube 2 are uniform.

[0028] Specifically, the thickness of the fabric layer 14 is 2 cm to 5 cm. The fabric layer 14 is supported by cotton cloth or non-woven fabric, has a soft texture, and can fit the outer periphery of the tank body 5. The fabric layer 14 has good water absorption performance, so that the cooling water can be evenly applied to the tank body 5, and the application effect is not easily affected by airflow.

[0029] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
