Description

Technical Field

[0001] The utility model relates to an exhaust device, in particular to an exhaust device for a purification tank. Background Art

[0002] At present, an exhaust pipe needs to be provided on the tank body of the purification tank, and then an exhaust device is used to connect the exhaust pipe to extract the exhaust gas from the tank body of the purification tank. This exhaust method has defects in actual use. For example, additional exhaust equipment is required to actively extract the exhaust gas. This is a power-driven extraction method, so it must be used in occasions with corresponding power supplies and other driving energy sources. Not only does it lead to certain restrictions on application occasions, but it also requires energy consumption and frequent maintenance, so it is more troublesome to use. At the same time, the external exhaust of the exhaust device can only be used to extract the exhaust gas within a limited number of times, and it is impossible to continuously extract the exhaust gas from the purification tank for a long time, so that the best exhaust effect cannot be achieved in the purification tank. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a purification tank exhaust device which is power-free, maintenance-free, energy-free, simple to use and has good exhaust effect.

[0025] A purification tank exhaust device, such as Figure 1 , Figure 7 As shown, it includes a full plastic tank body manufactured by rotational molding process, and the front and back sides of the tank body 1 are provided with multiple longitudinal reinforcement grooves 11, and the two side surfaces of the tank body are respectively provided with multiple transverse reinforcement grooves 12, and the strength of the tank body is improved by the multiple longitudinal reinforcement grooves 11 and the transverse reinforcement grooves 12. The top surface of the tank body 1 is provided with a tank mouth 13 for easy loading, and is also provided with a plurality of lifting holes 14 for easy lifting of the tank body 1.

[0026] The tank body 1 is provided with an exhaust pipe 2. In this embodiment, the exhaust pipe 2 is provided on one side of the top of the tank body. The specific structure is: a socket 21 made of PVC material is provided on one side of the top of the tank body 1, and the exhaust pipe 2 is an L-shaped pipe. The bottom end of the exhaust pipe 2 can be detachably inserted into the socket 21 from the horizontal direction, thereby forming a connected exhaust with the tank body 1.

[0027] The outlet of the exhaust pipe 2 is provided with a base 5 for covering and fixing. Figure 2 As shown, it is fixed to the pipe mouth of the exhaust pipe 2 by multiple screws 7 on the outer circumferential surface, and multiple exhaust holes 51 are provided on the outer circumferential surface of the base 5. The multiple exhaust holes are located above the multiple screws 7 and exceed the pipe mouth of the exhaust pipe 2, and the multiple exhaust holes 51 are connected to the exhaust pipe 2 at the same time to form exhaust.

[0028] The base 5 is provided with an exposed non-powered rotating fan blade 3 , and the blade shaft 31 of the non-powered rotating fan blade is supported by a double-track bearing 52 in the base 5 and is rotatably mounted.

[0029] At the same time, a water shield 6 is provided on the blade shaft 31, and the water shield covers the top of the base 5 and the plurality of exhaust holes 51 together to form a waterproof structure. Figure 3As shown, the water-blocking cover 6 is composed of a cylindrical cover 61 coaxially formed on the blade shaft 31 and a trumpet cover 62 extending outward from the lower end of the cylindrical cover. After the trumpet cover 62 extends outward from the bottom side of the unpowered rotating fan blade 3, it just covers and blocks the multiple exhaust holes 51 together, thereby preventing rainwater from flowing back into the tank body 1.

[0030] A spiral exhaust rod 4 is provided in the exhaust pipe 2, and the length of the spiral exhaust rod is adjusted according to the length of the L-shaped bend of the exhaust pipe 2. The spiral exhaust rod 4 is composed of a main rod 41 and a spiral blade 42 that is spirally arranged along the outer circumference of the main rod, and the top of the main rod 41 extends into the base 5 and is connected to the blade shaft 31 through a bolt 8, that is, the unpowered rotating fan blade 3 is connected to the spiral exhaust rod 4 through the blade shaft 31, so the unpowered rotating fan blade 3 can drive the spiral exhaust rod 4 to rotate when pushed by natural wind, and the rotating spiral exhaust rod 4 will directly stir the airflow in the exhaust pipe 2 to rise, so as to extract exhaust gas from the tank body 1, and then discharge the extracted exhaust gas from the multiple exhaust holes 51 at the top of the exhaust pipe 2.

[0031] Obviously, this extraction and exhaust method through the unpowered rotating fan blades 3 combined with the spiral exhaust rod 4 will neither cause energy loss nor require frequent maintenance. In other words, this is an unpowered, maintenance-free, zero-energy extraction and exhaust structure, so it is minimally restricted by application scenarios and is very simple to use.

[0032] Moreover, as long as there is natural wind, the natural wind is not limited by the wind force level. Even in the case of weak wind, the unpowered rotating fan blades 3 can rotate accordingly, thereby continuously extracting and exhausting the tank body 1 for a long time, so as to achieve a better exhaust effect.

[0033] In addition, the exhaust pipe 2, the unpowered rotating fan blade 3, the base 5, the bearing 52, the spiral exhaust rod 4 and the bolt 8 are all made of plastic, which is convenient for processing, manufacturing and installation.

[0034] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
