Description
Technical Field
[0001] This utility model relates to the field of spray fan technology, specifically a mining spray fan for mining engineering. Background Technology
[0002] Spray fans are a common type of humidification equipment, mainly used to reduce the dust content in the air. They are widely used in areas with high dust levels, such as construction sites and mining areas.
[0003] Most mining spray fans commonly found in the market today are similar in overall structure, consisting of a steel support frame on which a water tank, fan, water pump, and spraying components are installed. The fan has an exhaust pipe and an intake pipe at the front and rear. However, in actual use, they have some functional shortcomings and room for improvement. For example, in mining areas where operations are outdoors, the fan rapidly draws in outside air at its rear end. When lightweight objects such as plastic film are drawn into the fan's intake, it not only affects normal airflow but also easily damages the fan. Such situations require manual intervention; if not handled promptly, they can easily damage the equipment and affect dust suppression in the mining area. Furthermore, they lack the function of preventing the intake from being blocked.
[0004] Now, a new type of mining spray fan for mining engineering is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a mining spray fan for mining engineering, so as to solve the problem mentioned in the background art that it does not have the function of preventing the air inlet from being blocked.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a mining spray fan for mining engineering, comprising a bottom support frame, a first support frame welded to the right side of the top of the bottom support frame, a main water tank fixedly connected inside the first support frame, two sets of wheels movably connected to the bottom end of the bottom support frame, a traction frame movably connected to the left side of the bottom support frame, a water pump installed on the left side of the top of the bottom support frame, a fan support frame welded to the top of the first support frame, an axial flow fan movably connected to the top of the fan support frame, an air outlet duct fixedly connected to the left side of the axial flow fan, a first electric cylinder installed between the bottom end of the air outlet duct and the top end of the first support frame, an annular spray head fixedly connected to the left side of the air outlet duct, a flexible hose movably connected between the water pump and the annular spray head, an air inlet duct fixedly connected to the right side of the bottom support frame, and an air inlet assembly for preventing the air inlet from being blocked is provided inside the air inlet duct.
[0007] The air intake assembly includes two sets of second electric cylinders, which are respectively installed at the front and rear ends inside the air intake duct. A circular baffle is fixedly connected to the output end of the second electric cylinder. A wind speed sensor is installed at the middle position on the left side of the circular baffle. A buzzer is fixedly connected to the front end of the air intake duct.
[0008] As a further technical solution of this utility model, the outer diameter of the circular baffle is the same as the outer diameter of the right side of the air inlet duct, and the air inlet duct and the circular baffle are not connected.
[0009] As a further technical solution of this utility model, the second electric cylinder is symmetrically distributed about the horizontal center line of the air inlet duct, and the wind speed sensor, the second electric cylinder, and the buzzer are electrically connected.
[0010] As a further technical solution of this utility model, a secondary water tank is fixedly connected to the right side of the main water tank. Three sets of filter elements are horizontally placed inside the secondary water tank. Multiple sets of water outlets are opened at the bottom of the left side of the secondary water tank. A cover plate is fixedly connected to the top of the secondary water tank, and a water inlet connector is provided at the top of the cover plate.
[0011] As a further technical solution of this utility model, the shape and size of the filter element's exterior are adapted to the shape and size of the auxiliary water tank's interior, and the bottom of the filter element is higher than the bottom of the auxiliary water tank's interior.
[0012] As a further technical solution of this utility model, the main water tank, the auxiliary water tank, and the water outlet are internally connected, and the water outlets are arranged at equal intervals.
[0013] As a further technical solution of this utility model, a third electric cylinder is installed at each of the four corners of the top of the bottom support frame. The output end of the third electric cylinder is fixedly connected to a ground nail, and a support foot is fixedly connected to the outside of the ground nail.
[0014] As a further technical solution of this utility model, the bottom end of the ground nail is higher than the bottom end of the wheel, and the third electric cylinder is symmetrically distributed about the vertical center line of the bottom support frame.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the mining spray fan for mining engineering not only realizes the function of preventing the air inlet from being blocked, but also realizes the function of filtering water intake and preventing equipment displacement.
[0016] (1) By setting up an air inlet duct, a circular baffle, a wind speed sensor, a second electric cylinder and a buzzer, when in use, the axial flow fan starts and blows air continuously to the air outlet duct. The water pump pumps the water in the main water tank to the ring spray head through the hose. The strong airflow at the air outlet duct sprays out fine water mist from the ring spray head to reduce dust in the mining area. Outside air continuously flows in along the air inlet duct. When objects such as plastic film are drawn in by the airflow, the circular baffle blocks the film. The wind speed sensor senses that the airflow speed has decreased. The second electric cylinder extends outward and pushes the circular baffle to move outward, so that outside air can enter from the side without affecting the normal dust reduction work. At the same time, the buzzer sounds to remind the staff to clean in time, thus realizing the function of preventing the air inlet from being blocked.
[0017] (2) By setting up an auxiliary water tank, filter element, water outlet, cover plate and water inlet connector, when in use, the external water source is connected to the water inlet connector to continuously supply water to the main water tank, and the water flows into the auxiliary water tank. The three sets of filter elements can filter out floating objects and dust in the water body, avoiding clogging of the nozzles in the ring spray head. The water outlet connects the main water tank and the auxiliary water tank. The filter element can be replaced by opening the cover plate, thus realizing the function of filtering the incoming water.
[0018] (3) By setting a third electric cylinder, ground nails and support feet, when in use, on sloping or uneven ground, the third electric cylinder is turned on, the third electric cylinder pushes the ground nails downward and the ground nails are driven into the ground. At the same time, the support feet are pressed against the ground, which further improves stability and realizes the function of preventing equipment displacement. Attached Figure Description
