[0002] The waste heat recovery device project refers to a project that, in the industrial production process, through specific technologies and equipment, converts the waste heat generated in the production process into useful energy, such as steam, hot water, etc., and is reused for production or heating again to improve energy utilization efficiency, reduce production costs, and reduce environmental pollution. Such projects usually involve multiple aspects such as energy conversion, environmental protection, and economic benefits. The structure included in the waste heat recovery and reuse device generally has a collection mechanism, a conversion mechanism, a power mechanism, and other auxiliary mechanisms.

[0003] In the prior art, most waste heat recovery and reuse devices do not have a gas blocking mechanism. When the waste gas passes through the heating pipe, the speed is too fast, and the waste heat absorption efficiency is insufficient. It needs to be circulated multiple times for absorption, reducing the waste heat conversion efficiency and the practicability of the device. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a waste heat recovery and reuse device for factory production, aiming to improve the problems of low waste heat conversion efficiency and low practicability of the waste heat recovery and reuse device in the prior art due to the lack of a gas blocking mechanism.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A waste heat recovery and reuse device for factory production, including a water tank, an air inlet pipe is fixedly connected inside the water tank, a cold water pipe is fixedly connected inside the water tank, several baffles are rotatably connected inside the air inlet pipe, several outer shells are rotatably connected inside the air inlet pipe, a return spring is fixedly connected inside the outer shell, one end of the return spring away from the air inlet pipe is fixedly connected with a limit block, one side of the limit block away from the return spring is fixedly connected with a connection head, a filter screen is fixedly connected to one end of the air inlet pipe, and a cleaning mechanism is arranged on one side of the water tank, and the cleaning mechanism is provided for cleaning the filter screen.

[0006] As a further description of the above technical solution:

[0007] The cleaning mechanism includes an air pump, which is arranged on one side of the water tank. The output end of the air pump is fixedly connected with a connecting pipe, and a turbine is rotatably connected inside the connecting pipe. One side of the turbine away from the air pump is fixedly connected with a connecting shaft, and one end of the connecting shaft away from the turbine is fixedly connected with a mounting shell. A plurality of compression springs are fixedly connected inside the mounting shell. One end of the compression spring away from the mounting shell is fixedly connected with a limiting plate, one side of the limiting plate away from the compression spring is fixedly connected with a pressing plate, and one side of the pressing plate away from the limiting plate is fixedly connected with a brush.

[0008] As a further description of the above technical solution:

[0009] The limiting block is slidably connected inside the outer shell, and the connecting head penetrates through one side of the outer shell away from the air inlet pipe.

[0010] As a further description of the above technical solution:

[0011] One side of the connecting head away from the limiting block abuts against the baffle plate.

[0012] As a further description of the above technical solution:

[0013] The limiting plate is slidably connected inside the mounting shell.

[0014] As a further description of the above technical solution:

[0015] The pressing plate penetrates through one side of the mounting shell away from the connecting shaft.

[0016] As a further description of the above technical solution:

[0017] One side of the brush away from the pressing plate abuts against the filter screen.

[0018] As a further description of the above technical solution:

[0019] Anti-slip pads are arranged at the four corners of the bottom of the water tank.

[0020] The utility model has the following beneficial effects:

[0021] In the present utility model, the water tank is filled with water, cold water is injected into the cold water pipe, and the air pump is started to pump the waste gas into the intake pipe. When the waste gas flows in the intake pipe, it will impact the baffle. The baffle moves in the opposite direction of the impact and squeezes the return spring in the housing through the connector. The return spring rebounds, causing the baffle to rebound, which has the effect of resisting the gas flow, making the waste gas stay in the intake pipe for a longer time, extending the time for the water in the water tank to absorb heat, achieving the effect of blocking the gas flow from being too fast, making the gas stay in the intake pipe for a longer time, improving the waste heat absorption efficiency, and enhancing the practicality of the device.

[0022] In the present utility model, when the waste gas is transported to the connecting pipe through the air pump, an air flow is formed to impact the turbine and make it rotate. The turbine drives the connecting shaft, causing the mounting shell to rotate. The compression spring in the mounting shell provides elastic force to push the pressing plate through the limiting plate, so that the brush always adheres to the surface of the filter screen for automatic cleaning, achieving the effect of automatic cleaning of the filter screen, without the need to remove the filter screen for cleaning, and improving the practicality of the device.
