Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a mine explosion-proof concrete mixing tank radiator. Background Technology

[0002] In mining operations, concrete silos rely on a highly efficient and stable hydraulic system to achieve the functions of rotating and mixing the silo. An engine serves as the power source, driving an oil pump that converts mechanical energy into hydraulic energy, which in turn drives a hydraulic motor. The hydraulic motor is connected to the concrete silo via a precision reducer, smoothly transmitting rotational power to the silo and thus achieving uniform mixing of the concrete.

[0003] Hydraulic systems inevitably generate a significant amount of heat during operation. If this heat is not dissipated in time, the system oil temperature will rise, affecting the performance and lifespan of hydraulic components and potentially leading to serious safety accidents. Therefore, the configuration of a radiator is crucial for the stable operation of a hydraulic system.

[0004] In conventional industrial applications, radiators are typically driven by electric fans. However, in the unique working environment of mines, air circulation is poor, and flammable and explosive gases are present. Electric fans may explode due to electrical sparks or high temperatures during operation, posing a significant threat to the lives of workers and mine facilities. Furthermore, mines are filled with large amounts of dust, coal dust, and other debris. These tiny particles are easily attracted to and adhere to the surface of the fan blades during high-speed rotation. Over time, this not only increases the weight of the fan blades, potentially causing friction and wear between the blades and other radiator components, but may also alter the aerodynamic characteristics of the blades, reducing heat dissipation efficiency. Therefore, this invention provides a mine-use explosion-proof concrete mixing tank radiator to solve the problems mentioned in the background. Utility Model Content

The hydraulic motor drives the fan blades to effectively dissipate heat from the hydraulic system, while avoiding circuit explosion accidents and ensuring safety in mining conditions. Furthermore, by setting filter screens and baffles on both sides of the fan blades, the adhesion of dust and other impurities on the fan blades can be reduced, thereby reducing fan blade imbalance and wear caused by dust accumulation.

A hydraulic motor 2 is fixedly connected to the side of the mounting frame 1 opposite to the fan blade 4. The end of the rotating shaft 3 opposite to the fan blade 4 is fixedly connected to the output shaft of the hydraulic motor 2.

[0027] The concrete hopper is driven by a hydraulic system. A small hydraulic motor 2 is connected in series in the hydraulic system circuit. The hydraulic motor 2 drives the fan blades 4, which can effectively dissipate heat from the hydraulic system and avoid circuit explosion accidents, thus ensuring safety in mining conditions.

[0028] A filter screen 5 is provided on the side of the mounting bracket 1 near the hydraulic motor 2. A mesh cover 6 is inserted into the inside of the mounting bracket 1 near the filter screen 5. The filter screen 5 is located between the mesh cover 6 and the mounting bracket 1. Multiple connecting components for positioning the mesh cover 6 are evenly provided on the outer side of the mounting bracket 1. The connecting components include a mounting plate 11 fixedly connected to one side of the mounting bracket 1, a screw 12 threadedly connected to the inside of the mounting plate 11, a pressure plate 13 rotatably connected to one end of the screw 12, a connecting plate 10 fixedly connected to one side of the mesh cover 6, and a knob 14. The connecting plate 10 is located between the pressure plate 13 and the mounting bracket 1, and the pressure plate 13 is slidably connected to the outer side of the mounting plate 11. The knob 14 is fixedly connected to one end of the screw 12 and the pressure plate 13.

[0029] A filter screen 5 installed on one side of the fan blade 4 can prevent mineral dust and impurities from entering the radiator. The filter screen 5 is installed on the mounting bracket 1 by a movable connection. When it is necessary to clean the filter screen 5, loosen the screw 12 to separate the pressure plate 13 from the connecting plate 10, rotate the screen cover 6 to a certain angle, and then remove the filter screen 5 from the mounting slot area of ​​the mounting bracket 1 for easy cleaning and to ensure good protection.

[0030] A mounting bracket 1 is fixedly connected to a fixing cover 7 on the side near the fan blade 4. The front side of the fixing cover 7 is provided with multiple baffles 9.

[0032] To improve the corrosion resistance of the radiator and extend its service life, the outer sides of the mounting bracket 1, the mesh cover 6, and the fixing cover 7 are all coated with anti-corrosion coatings, which can effectively resist the moisture and corrosion factors in the mining environment and protect the radiator.

[0033] Working principle: The concrete hopper is driven by a hydraulic system. A small hydraulic motor 2 is connected in series in the hydraulic system circuit. The fan blades 4 driven by the hydraulic motor 2 can effectively dissipate heat from the hydraulic system and at the same time avoid circuit explosion accidents, ensuring safety in mining conditions.

[0034] When the fan blade 4 is in use, the filter screen 5 installed on one side of the fan blade 4 can prevent mineral dust and impurities from entering the radiator.

At the same time, the fixed cover 7 and the baffle 9 form a protective structure, which can be placed on the outside of the fan blade 4 when it is not rotating to reduce the adhesion of dust. Moreover, the flexible baffle 9 can swing flexibly under the action of airflow to facilitate the blowing of air.
