Description

Technical Field

[0001] This utility model belongs to the technical field of coal conveying devices, and in particular relates to a coal conveying device that can improve the thermal efficiency of a boiler. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. It requires a coal conveying device to transport the fuel.

[0003] The existing coal conveying equipment for boilers mostly uses double-roll crushers for crushing. When the material is discharged, the particles are too large to meet the normal combustion requirements of the boiler. This makes it difficult for the coal fed into the boiler to burn thoroughly, reducing the boiler's working efficiency. At the same time, the large coal particles can clog the slag discharge pipe, making it difficult for the coal conveying equipment to deliver coal into the boiler, thus reducing the boiler's thermal efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a coal conveying device that can improve the thermal efficiency of a boiler. Specifically, a third motor is installed, with a rotating shaft fixedly connected to its bottom output end. A circular plate is fixedly connected to the bottom of the rotating shaft, and a connecting column is fixedly connected to the bottom of the circular plate away from the shaft center. A connecting rod is rotatably connected to the outer surface of the connecting column, and a fixed rod is rotatably connected to one side of the bottom of the connecting rod. A screen plate is fixedly connected to one side of the fixed rod. In use, starting the third motor drives the connecting column and connecting rod, causing the fixed rod to drive the screen plate to screen the crushed coal. This isolates and recovers larger pieces of coal, while smaller pieces enter the filter for combustion, ensuring normal boiler combustion and thus improving boiler thermal efficiency. This solves the problem in existing boiler coal conveying devices, where the crushing structure mostly uses roller crushers. At the discharge point, the particles are too large to meet the normal combustion requirements of the boiler, resulting in incomplete combustion of the coal and reduced boiler efficiency. Furthermore, the large coal particles can clog the slag discharge pipe, making it difficult for the coal conveying device to deliver coal into the boiler, further reducing boiler thermal efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a coal conveying device that can improve the thermal efficiency of a boiler. It includes a base plate, a first motor fixedly connected to the front of the base plate, a track fixedly connected to one output end of the first motor, a main support frame fixedly connected to the bottom inner wall of the base plate, a double-roll crusher body fixedly connected to the top surface of the main support frame, a third motor fixedly connected to one side of the top surface of the main support frame, a rotating shaft fixedly connected to one output end of the third motor, a circular plate fixedly connected to the bottom of the rotating shaft, a connecting column fixedly connected to the bottom of the circular plate away from the axis, a connecting rod rotatably connected to the outer surface of the connecting column, and a fixing rod rotatably connected to the bottom of the connecting rod. A screen plate is fixedly connected to one end of a fixed rod. A third motor is installed, specifically, a rotating shaft is fixedly connected to the bottom output end of the third motor, a circular plate is fixedly connected to the bottom of the rotating shaft, a connecting column is fixedly connected to the bottom of the circular plate away from the shaft center, a connecting rod is rotatably connected to the outer surface of the connecting column, a fixed rod is rotatably connected to one side of the bottom surface of the connecting rod, and a screen plate is fixedly connected to one side of the fixed rod. In use, the third motor is started to drive the connecting column and the connecting rod, so that the fixed rod drives the screen plate to screen the crushed coal, so that larger pieces of coal are isolated and recovered, and smaller pieces of coal enter the filter for combustion, which meets the normal combustion of the boiler and thus improves the thermal efficiency of the boiler.

[0007] Furthermore, the screen plate has several filter holes, each with a diameter of 10 mm. Baffles are fixedly connected to both sides of the screen plate. By setting the screen plate, specifically, the screen plate has several filter holes with a diameter of 10 mm, and baffles are fixedly connected to both sides of the screen plate, the coal crushed by the double roll crusher can be filtered during use. Coal larger than 10 mm is filtered out, ensuring control of the coal size and further improving the thermal efficiency of the boiler.

[0008] Furthermore, a secondary support frame is provided on the outer surface of the base plate. The secondary support frame is fixedly connected to the body of the double roll crusher. By setting the secondary support frame, the body of the double roll crusher is further fixed and supported, thereby enhancing the overall stability of the device.

[0009] Furthermore, a second motor is fixedly connected to the front of the double roll crusher body, a feed inlet is provided at the top of the double roll crusher body, and a guide inlet is provided at the bottom of the double roll crusher body. By setting the guide inlet, the material can be guided to the guide screen plate after the double roll crusher body crushes the material, thereby improving the linkage of the device and enhancing the working quality of the device.

[0010] Furthermore, the fixed rod is slidably connected to the inner wall of the chute. Through the slidable connection between the fixed rod and the inner wall of the chute, the fixed rod can drive the screen plate to run stably, ensuring support for the fixed rod and making the third motor and the screen plate more stable during operation, without unnecessary shaking.

[0011] Furthermore, the screen plate is located below the feed inlet, and the screen plate is set at an angle. The angled setting of the screen plate enables the collection of large pieces of material filtered out, thus achieving the discharge capability of the device.

[0012] This utility model has the following beneficial effects:

A connecting rod is rotatably connected to the outer surface of the connecting column, and a fixed rod is rotatably connected to one side of the bottom surface of the connecting rod. A screen plate is fixedly connected to one side of the fixed rod. In use, the third motor is started to drive the connecting column and the connecting rod, causing the fixed rod to drive the screen plate to screen the crushed coal. This isolates and recovers larger pieces of coal, while smaller pieces of coal enter the filter for combustion, ensuring normal combustion in the boiler and thus improving the boiler's thermal efficiency.
