Description

Technical Field

[0001] This utility model relates to the field of zinc oxide production technology, specifically to a feed conveying device for a rotary kiln with anti-backflow function for zinc oxide. Background Technology

[0002] Currently, the production and processing technology of zinc oxide is quite mature, and it is mostly processed according to the following process route: First, zinc ingots are melted into molten zinc, then the molten zinc is heated and vaporized, and finally the gaseous zinc is oxidized and recovered. Among them, the melting and vaporization of zinc is one of the key processes in the production process. Because zinc has a high melting point and boiling point, the requirements for the heat source are extremely high.

[0003] As disclosed in CN209322487U, a feeding and conveying device for a rotary kiln with anti-backflow function for zinc oxide includes, from bottom to top, a fuel platform, a heating chamber, and an oxidation chamber. The fuel platform has a fuel pipe, one end of which is connected to the top surface of the fuel platform and located at its center. The oxidation chamber is fixedly connected to the top surface of the heating chamber and is partially covered by several gasification crucibles. An oxygen inlet is provided on the wall of the oxidation chamber, and a discharge pipe is located at the top of the oxidation chamber. The oxygen inlet is connected to a low-temperature oxygen pipe, and a low-temperature oxygen generator is located on the side of the low-temperature oxygen pipe furthest from the oxidation chamber. This invention has advantages such as compact structure, high processing efficiency, good stability, convenient operation, and long service life.

[0004] However, the existing technology CN209322487U patent has significant limitations because the feed conveying device for a rotary kiln with anti-backflow function for zinc oxide does not have anti-backflow function; the device cannot effectively replenish air to the cylinder as needed, resulting in low efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a feeding and conveying device for a rotary kiln with anti-backflow function for zinc oxide, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a kiln head hood is included, one end of which is fixedly connected to a decorative frame, and a feed pipe is provided at the end away from the decorative frame. An anti-backflow mechanism is fixedly installed inside the feed pipe.

[0007] The anti-backflow mechanism includes a fixed block, one end of which is fixedly connected to a limit spring, the bottom end of which is fixedly connected to a baffle, and the bottom end of which is movably connected to a stop block.

[0008] Preferably, an air inlet pipe is fixedly connected to the top of the kiln head hood, and an air inlet is opened at the top of the air inlet. A filter screen is fixedly connected inside the air inlet. By setting up the air inlet pipe, air inlet and filter screen, the fixed installation of the filter screen is facilitated, further improving the air supply effect of the device and improving its working efficiency, thereby achieving the purpose of improving the working efficiency of the device.

[0009] Preferably, a cylindrical body is movably connected to the other end away from the decorative frame. The cylindrical body and the movable cylinder are sleeved together. A fixed recess is fixedly connected to the top of the movable cylinder. A rotating belt is movably connected inside the fixed recess. By setting the movable cylinder, the fixed recess, and the rotating belt, the installation and use of the fixed recess and the rotating belt are facilitated, and the movement of the cylindrical body is driven, thereby achieving the purpose of driving the movement of the cylindrical body.

[0010] Preferably, a base is fixedly connected to the bottom end of the movable cylinder, and a plurality of telescopic rods are fixedly connected to the bottom end of the base. A universal wheel is fixedly connected to the bottom end of the telescopic rod, and a fixing buckle is movably connected to the top end of the universal wheel. By setting the telescopic rod, universal wheel, and fixing buckle, the operator pushes the device to move it to the designated position through the universal wheel. After reaching the position, the fixing buckle is pressed down to fix the device. The overall height of the device is then adjusted by using the telescopic rod, thereby achieving the purpose of moving the device.

[0011] Preferably, an adjuster is fixedly connected to one end of the base, and a screen and several adjustment buttons are fixedly connected to one end of the adjuster. By setting the adjuster, the installation of the adjuster, screen and adjustment buttons facilitates the control of the device, thereby achieving the purpose of controlling the device.

[0012] Preferably, a kiln tail smoke chamber is fixedly connected to the bottom end of the cylinder. One end of the kiln tail smoke chamber has a smoke outlet. A plug is movably connected inside the smoke outlet, and a handle is fixedly connected to the top of the plug. By configuring the kiln tail smoke chamber, the smoke outlet, the plug, and the handle, the device generates a large amount of smoke during operation, which accumulates in the kiln tail smoke chamber. The operator opens the plug using the handle, allowing the smoke to escape from the smoke outlet, thus achieving the purpose of smoke dispersion.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A rotary kiln feeding and conveying device with anti-backflow function for zinc oxide. By setting up an anti-backflow mechanism, the operator conveys zinc oxide from the feed pipe. During the conveying process, the zinc oxide enters from the feed pipe and pushes open the baffle to allow the zinc oxide to enter. However, if the zinc oxide wants to flow back from the cylinder to the feed pipe, the baffle will be blocked by a stop block when the zinc oxide reaches the baffle, thus preventing the backflow of zinc oxide.

[0015] 2. This rotary kiln feeding and conveying device for zinc oxide with anti-backflow function, by setting up an air inlet pipe, an air inlet and a filter screen, facilitates the fixed installation of the filter screen through the installed air inlet pipe and air inlet, further improving the air supply effect of the device and increasing its working efficiency.
