DETAILED DESCRIPTION

[0019] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0020] Example

[0021] like Figure 1-Figure 4As shown: A spray box of an exhaust gas treatment device, comprising: a fixed bracket 2 is provided at the bottom of a shell 1 to ensure that the entire shell structure can be stably placed or installed in a working position. This design takes into account the stability and safety in actual use and effectively prevents the shell from shifting or tipping over.

[0022] A sealing cover 3 is provided on the top of the housing 1. The sealing cover is made of a material with good sealing performance to prevent leakage of liquid or gas. An impeller cover 4 is further provided on the top of the sealing cover 3. An impeller 5 is provided inside the impeller cover. The design of the impeller can achieve uniform distribution and effective spraying of the liquid.

[0023] In order to introduce the liquid into the impeller cover 4, a liquid inlet pipe 6 is arranged on one side of the impeller cover. Through the liquid inlet pipe, the liquid can smoothly enter the impeller cover and interact with the impeller, thereby achieving uniform spraying of the liquid.

[0024] Inside the impeller cover 4, the impeller 5 is fixedly connected to the cleaning plate 8 through the rotating rod 7. When the impeller rotates, the cleaning plate also moves with the connection between the rotating rod and the cleaning plate to clean the inner wall. This design not only realizes the spraying of liquid, but also facilitates the cleaning and maintenance of the inner wall.

[0025] Inside the housing 1, there is an inner liner bracket 9, which is fixedly connected to the inner liner 10. The inner liner is designed to contain and treat exhaust gas. A sewage discharge port 11 is provided at the bottom of the inner liner to facilitate regular cleaning and discharge of treated liquid and sediment.

[0026] In order to achieve uniform spraying of the liquid, a spray head 13 is provided at the bottom of the sealing cover 3. The design of the spray head takes into account the spraying effect and coverage range, ensuring that the liquid can be evenly sprayed on the inner tank and the tail gas, fully contacting and reacting.

[0027] It can be understood that the impeller cover 4 is an important protective component, which can prevent external impurities from entering and interfering with the internal rotating parts. At the same time, the impeller cover also plays a role in fixing and supporting the rotating parts to ensure its stable operation.

[0028] Inside the impeller cover 4, a rotating shaft 401 is provided. The rotating shaft is a strong and durable part, one end of which is fixedly connected to the impeller 5. The impeller is the core component of the spray box, responsible for evenly distributing and spraying the liquid. The fixed connection between the rotating shaft and the impeller ensures the stability and reliability of the impeller during the rotation process.

[0029] The other end of the rotating shaft 401 is fixedly connected to one end of the rotating rod 7. The rotating rod is an important transmission component that connects the rotating shaft and the outside of the impeller cover. It can transmit external power to the rotating shaft and the impeller to make them rotate. Through the connection of the rotating rod, the power transmission and the driving of the rotating parts are realized.

[0030] In this structure, when external power acts on the rotating rod, the impeller starts to rotate through the transmission of the rotating shaft, and at the same time drives the cleaning plate to move together, ensuring the overall cleaning of the inner wall of the inner tank.

[0031] It is understood that the rotating rod 7 is a solid transmission component, and its main function is to transmit external power to the rotating shaft and the impeller to rotate. In the structure described herein, one end of the rotating rod is fixedly connected to the rotating shaft, and the other end is clamped inside the inner container 10. This clamping structure ensures a stable connection between the rotating rod and the inner container, and can withstand the torque and impact force generated during the rotation process.

[0032] A second cleaning plate 701 having a conical shape is provided on the side of the rotating rod close to the inner container. The conical design of the cleaning plate enables it to better adapt to the shape of the inner wall of the inner container and achieve a tighter press-fit connection. This tight press-fit connection ensures that the cleaning plate can effectively remove stains and sediments on the inner wall of the inner container.

[0033] The second cleaning plate 701 can be made of a material with good cleaning effect and durability to ensure that it can effectively remove stains and has a long service life. At the same time, the surface of the cleaning plate is smooth to reduce friction resistance with the inner wall of the inner tank and maintain stable operation of the rotating rod.

[0034] When the rotating rod rotates, the second cleaning plate is tightly pressed and connected to the inner wall of the inner tank, so that the cleaning plate can remove stains and sediments on the inner wall of the inner tank. This cleaning action can improve the cleanliness of the inner tank and ensure the purity and effect of the spray liquid.

[0035] It is understood that the main body of the liner is a cylindrical shell 1001, which has a large internal volume and can accommodate enough liquid for spraying. The shape of the cylindrical shell makes it stable and has good liquid retention performance, ensuring the continuity and uniformity of the spraying process.

[0036] A conical shell 1002 is provided below the cylindrical shell 1001. The design of the conical shell makes the bottom of the inner tank present a gradually contracting shape, which helps to concentrate and discharge the liquid smoothly. The angle and shape of the conical shell are carefully designed to ensure that the liquid can flow smoothly to the drainage end at the bottom to avoid accumulation of liquid and blockage.

[0037] A clamping block 1003 is provided at the central axis of the conical housing 1002. The clamping block is a block structure with a specific shape, and its function is to fix the sewage discharge end 11 and ensure the sealing performance between the sewage discharge end and the inner tank. The material of the clamping block can be selected from corrosion-resistant and high-temperature resistant engineering plastics or metal materials to ensure its stability and reliability in long-term use.

[0038] A drainage trough 1004 is provided on the clamping block 1003. The drainage trough is a channel with appropriate width and depth for discharging liquid and sediment from the inner tank. The design of the drainage trough takes into account the fluidity of the liquid and the discharge effect of the sediment to ensure efficient and smooth drainage. At the same time, the position and number of the drainage troughs can also be adjusted and optimized according to actual needs.

[0039] The clamping block 1003 is connected to the drain end 11 by a fixed connection. The drain end is an outlet for discharging liquid and sediment, and is usually set at the lowest point of the bottom of the inner tank. The fixed connection of the clamping block ensures the stability and sealing of the drain end, preventing liquid leakage and the influence of the external environment on the inner tank.

[0040] The working process of the utility model is as follows: first, the fixed bracket at the bottom ensures the stability of the spray box. The sealing cover and impeller cover on the top of the outer shell constitute the main closed structure, which is used to prevent liquid leakage and protect internal components. The impeller inside the impeller cover introduces liquid through the liquid inlet pipe to form a spray, and is connected to the rotating rod and the cleaning plate through the rotating shaft. The impeller generates a rotating force through the water flow power to clean the inner wall of the liner. The liner bracket is fixedly connected to the liner, and a sewage discharge end is provided at the bottom of the liner, and an air inlet end is provided on one side for receiving and discharging exhaust gas. The spray head is located at the bottom of the sealing cover and is used to spray liquid, thereby ensuring the stability of the internal structure of the spray box.

[0041] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
