Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a multi-point feeder for alternative fuel cement kilns. Background Technology

[0002] Globally, traditional fossil fuel reserves are dwindling, and an energy crisis is emerging. The cement industry, as a high-energy-consuming sector, has a huge demand for fuel and urgently needs to find alternative energy sources. Simultaneously, environmental policies are becoming increasingly stringent, with countries imposing stricter restrictions on carbon and pollutant emissions. As a major carbon emitter, the cement industry faces an urgent need to reduce its use of traditional fossil fuels and decrease pollutant emissions. Under these circumstances, utilizing combustible solid waste such as municipal solid waste, sewage sludge, and industrial waste as alternative fuels can alleviate energy pressure, achieve resource utilization of solid waste, and reduce environmental pollution, becoming an important development direction for the cement industry. Therefore, a multi-point feeder for cement kilns using alternative fuels is needed.

[0003] Traditional single-point feeding methods may lead to uneven fuel distribution in the kiln when using alternative fuels, which can easily result in incomplete combustion in certain areas, affecting the quality of cement clinker and potentially increasing pollutant emissions. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-point feeder for alternative fuel cement kilns, to solve the problems mentioned in the background art, such as uneven fuel distribution in the kiln when using alternative fuels, which can easily lead to incomplete combustion in certain areas, affecting the quality of cement clinker, and potentially increasing pollutant emissions. To achieve the above objective, this utility model provides the following technical solution: a multi-point feeder for alternative fuel cement kilns, including a storage tank;

[0005] A feeding assembly includes a feeding pipe, which is fixedly connected to the bottom of the storage tank. A conveying frame is fixedly connected to the bottom of the feeding pipe. A conveying motor is fixedly connected to one side of the conveying frame. A conveying auger is fixedly connected to the drive end of the conveying motor. A feeding pipe is fixedly connected to the bottom of the conveying frame. A feeding control valve is installed on the side surface of the feeding pipe.

[0006] An auxiliary component, comprising a support frame disposed below the storage tank, and a support plate disposed below the conveying frame.

[0007] More preferably, the feeding assembly is located on one side of the storage tank, the auxiliary assembly is located on one side of the storage tank, and an extension plate is fixedly connected to one side of the conveying frame. The conveying motor is mounted on the top of the extension plate by screws. By installing the feeding assembly, the alternative fuel stored in the storage tank can first enter the discharge pipe and then fall into the conveying frame. After the conveying motor starts, its transmission end drives the conveying auger to rotate. The rotating conveying auger can push the alternative fuel in the conveying frame evenly and continuously towards the feeding pipe. When the alternative fuel reaches the feeding pipe, the amount and timing of the alternative fuel can be precisely controlled by controlling the opening and closing of the discharge control valve and adjusting its opening degree. This allows the alternative fuel to be accurately and stably transported to the designated position in the cement kiln through the feeding pipe according to production needs, thereby achieving multi-point and controllable feeding of the alternative fuel, ensuring the uniformity and stability of fuel combustion in the cement kiln, and thus improving the utilization efficiency of the alternative fuel.

[0008] Further preferably, the auxiliary component also includes a bearing groove, which is formed inside the support frame. The storage tank is installed inside the support frame through the bearing groove. The bottom of the conveying frame has a fitting groove. The internal thread of the support plate is connected to a fitting bolt. The bottom of the support plate is fixedly connected to a counterweight seat. The support plate is installed at the bottom of the conveying frame through the fitting bolt.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In this invention, by installing a feeding assembly, the alternative fuel stored in the storage tank first enters the feeding pipe and then falls into the conveying frame. After the conveying motor starts, its transmission end drives the conveying auger to rotate. The rotating conveying auger can push the alternative fuel in the conveying frame evenly and continuously towards the feeding pipe. When the alternative fuel reaches the feeding pipe, the feeding amount and timing of the alternative fuel can be precisely controlled by controlling the opening and closing of the feeding control valve and adjusting its opening degree. This allows the alternative fuel to be accurately and stably transported to the designated position in the cement kiln through the feeding pipe according to production needs, thereby achieving multi-point and controllable feeding of the alternative fuel, ensuring the uniformity and stability of fuel combustion in the cement kiln, and thus improving the utilization efficiency of the alternative fuel.

[0012] In this invention, by installing auxiliary components, the support frame can support and position the storage tank through its internal bearing groove, ensuring stable placement of the storage tank and preventing shaking or displacement during fuel storage and feeding. The support plate below the conveying frame engages with the conveying frame through a fitting groove, and the two are securely fixed by the threaded connection of the fitting bolt. At the same time, the counterweight at the bottom of the support plate increases the overall weight, further enhancing the stability of the conveying frame and preventing the conveying frame from shifting due to vibration when the conveying motor is working. This ensures that the feeding component remains stable during conveying and feeding, thus providing a reliable guarantee for the accurate delivery of alternative fuels. Attached Figure Description
