Description

Technical Field

[0001] The utility model belongs to the technical field of thermal power plants, in particular to a fuel transmission device for a thermal power plant. Background Art

[0002] A thermal power plant is the abbreviation of a thermal power plant. It is a factory that uses combustible materials as fuel to produce electricity. Its basic production process is that the fuel heats water to generate steam when it burns, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. The turbine then drives the generator to rotate, converting the mechanical energy into electrical energy. The fuel of a thermal power plant includes coal, and a thermal power plant fuel transmission device is involved when transmitting the fuel.

[0003] When the fuel transmission device of a thermal power plant is in use, the fuel is in granular form and is prone to inertial bounce during transportation, making it difficult to concentrate the fuel bounce. Therefore, the designed feed guide structure prevents the fuel from bouncing during transportation and avoids fuel clutter in the working area. Utility Model Content

[0004] The utility model provides a fuel transmission device for a thermal power plant, aiming to solve the problem that the fuel in the thermal power plant is easily scattered during the fuel delivery.

[0005] The utility model is implemented as follows: a fuel transmission device for a thermal power plant includes a base, a mounting shell is fixed to one side of the top of the base, a mounting frame is fixed to the top of the base, a conveyor belt is provided at the other end of the mounting frame, a limit block is fixed to one end of the mounting frame, a protective plate is provided inside the limit block, a feed port is provided at the top of the mounting shell, a crushing structure is provided inside the feed port, and a material guide structure is provided at the top of the interior of the mounting shell;

[0006] The material guiding structure includes a groove, which is arranged at the top of the mounting shell, a locking block is arranged inside the groove, a bolt is arranged inside the locking block, the bottom end of the locking block is fixed with a mounting block, and the bottom end of the mounting block is fixed with a material guiding cloth bag.

[0007] Preferably, the inner diameter of the groove is larger than the outer diameter of the engaging block, and the groove and the engaging block form an engaging structure.

[0008] Preferably, two groups of the engaging blocks are provided, and the two groups of the engaging blocks are symmetrically distributed about the central axis of the mounting block.

[0009] Preferably, the crushing structure includes a connecting shaft, which is arranged on the inner wall of the feed port, a connecting rod is provided on one side of the connecting shaft, a crushing knife is fixed on the outer wall of the connecting rod, and a motor is installed on the other side of the feed port.

[0011] Preferably, a plurality of crushing knives are provided, and the plurality of crushing knives are distributed at equal intervals on the outer side wall of the connecting rod.

[0012] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0013] By setting up a feed introduction structure, two groups of grooves are provided, which are symmetrically arranged at the top of the interior of the mounting shell. Through the clamping structure of the grooves and the clamping blocks, the two groups of clamping blocks can be correspondingly limited inside the grooves. When the bolts are screwed into the clamping blocks, the mounting blocks are limited at the top of the interior of the mounting shell. After the feed port is fed, the fuel can fall onto the conveyor belt through the feed introduction bag, avoiding the fuel from bouncing when transporting the falling material, causing the fuel to scatter unevenly.

[0023] It should be noted that, due to the problem that the fuel in the thermal power plant is easy to fly when being transported, this solution is provided with a guide structure 7, and two groups of grooves 701 are provided, which are symmetrically arranged at the top of the inside of the mounting shell 2. Through the engaging structure of the grooves 701 and the engaging blocks 702, the two groups of engaging blocks 702 can be correspondingly limited inside the grooves 701, and the bolts 703 are screwed into the inside of the engaging blocks 702, so that the mounting block 704 is limited at the top of the inside of the mounting shell 2, so that after the feed port 5 is fed, the fuel can fall onto the conveyor belt 4 through the guide bag 705, thereby avoiding the fuel from bouncing when transporting the blanks and causing the fuel to fly unevenly.

[0024] Specifically, in this embodiment, this scheme mainly includes a feed introduction structure 7, which includes a groove 701. The groove 701 is arranged at the top of the interior of the mounting shell 2. A locking block 702 is arranged inside the groove 701. A bolt 703 is arranged inside the locking block 702. The bottom end of the locking block 702 is fixed with a mounting block 704. The bottom end of the mounting block 704 is fixed with a feed introduction bag 705. First, a groove 701 is opened at the top of the interior of the mounting shell 2, and then the locking block 702 is symmetrically fixed to the top of the mounting block 704, and then the feed introduction bag 705 is fixed to the top of the mounting block 704. Then, the locking block 702 is correspondingly locked in the interior of the groove 701, and then the bolt 703 is correspondingly screwed into the interior of the locking block 702, so that the mounting block 704 is fixed to the top of the interior of the mounting shell 2, so that the fuel has a feed introduction structure during transportation to avoid fuel splashing.

[0025] In a further preferred embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the inner diameter of the groove 701 is larger than the outer diameter of the locking block 702. The groove 701 and the locking block 702 constitute a locking structure. There are two groups of locking blocks 702. The two groups of locking blocks 702 are symmetrically distributed about the central axis of the mounting block 704. The locking structure of the groove 701 and the locking block 702 enables the mounting block 704 to be limited at the top end inside the mounting shell 2. The symmetrical distribution of the locking blocks 702 enables the two groups of locking blocks 702 to be correspondingly limited inside the groove 701, making the limitation of the mounting block 704 more stable.

[0026] Specifically, in this embodiment, this scheme mainly includes a crushing structure 6, which includes a connecting shaft 603. The connecting shaft 603 is arranged on the inner wall of the feed port 5. A connecting rod 602 is provided on one side of the connecting shaft 603. A crushing knife 601 is fixed on the outer wall of the connecting rod 602. A motor 604 is installed on the other side of the feed port 5. First, the motor 604 is installed on the other side of the feed port 5, and then the crushing knife 601 is fixed on the outer wall of the connecting rod 602 at equal intervals. Then, the two sets of connecting shafts 603 are symmetrically connected on both sides of the connecting rod 602, and then the connecting shaft 603 is installed on the inner wall of the feed port 5. The motor 604 is started so that the motor 604 drives the connecting shaft 603 to rotate, so that the connecting rod 602 can drive the crushing knife 601 to rotate inside the feed port 5, thereby crushing the fuel entering the feed port 5. The larger volume of fuel inside blocks the feed port 5 and affects the fuel transmission.

[0027] In a further preferred embodiment of the present invention, Figure 1 and Figure 2As shown, the connecting shaft 603 and the motor 604 are on the same horizontal plane, and the connecting shaft 603 and the motor 604 form a linkage structure. A plurality of crushing knives 601 are provided, and the plurality of crushing knives 601 are evenly spaced on the outer wall of the connecting rod 602. Through the linkage structure of the connecting shaft 603 and the motor 604, the motor 604 can drive the connecting shaft 603 to rotate. The evenly spaced distribution of the crushing knives 601 enables the crushing knives 601 to rotate along with the connecting rod 602, thereby crushing the fuel more carefully.
