Abstract
Description
Technical Field
[0001] This utility model belongs to the field of loading and unloading technology, and in particular to a fuel loading and unloading device for cogeneration. Background Technology
[0002] Combined heat and power (CHP) refers to a combined production process that simultaneously generates electricity and heat. It utilizes the chemical energy of fuel to produce both, maximizing fuel energy efficiency and reducing energy waste. During CHP, fuel loading and unloading are necessary for the unit to generate electricity and produce heat. Existing loading and unloading systems pre-treat the fuel, removing impurities, but this process involves discharge, which can negatively impact the working environment and the health of workers.
[0003] A search revealed a Chinese patent document (authorization announcement number CN220793173U) entitled "An Improved Fuel Loading and Unloading Device for Cogeneration," belonging to the field of cogeneration technology. The device includes a base on which a drive motor is fixedly mounted. Two movable plates are symmetrically arranged on the output shaft of the drive motor, and telescopic rods are fixedly mounted on both sides of each movable plate. An extension plate is movably mounted on the side of each movable plate away from the drive motor. Grooves are formed on the side of each extension plate closest to the movable plate, and the ends of the telescopic rods extend into the grooves and are fixedly connected to the extension plates. This invention, by incorporating a drive motor, facilitates continuous loading and unloading of the movable plates. The telescopic rods increase the loading range. The fan dries the fuel and removes fine impurities, improving combustion efficiency and providing convenience. While it can handle impurities, the method of discharge can affect the working environment and personnel. Utility Model Content
[0004] The purpose of this invention is to provide a fuel loading and unloading device for cogeneration to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cogeneration fuel loading and unloading device, comprising:
[0006] Car body;
[0007] The assembly plate is welded to the top of the vehicle panel. Linear motors are embedded in both sides of the assembly plate. The moving part of the linear motor is fixedly connected to the side support plate. The side of the side support plate is detachably connected to the loading and unloading box for loading and unloading cogeneration fuel.
[0008] The inclined filter frame is detachably connected to the inner wall of the loading and unloading box. The top of the filter frame is connected to a wire mesh for filter support. An inclined unloading hopper is embedded in one side of the loading and unloading box. The bottom of the unloading hopper has an unloading port. A sealing plate for blocking the unloading port is set below the unloading hopper. A U-shaped limiting plate for limiting the sealing plate is connected to the bottom of the unloading hopper.
[0009] A discharge plate is rotatably connected to the side of the loading and unloading box away from the discharge hopper. Multiple fans are embedded in the side of the discharge plate. An L-shaped vent pipe is connected to the side of the fan. A threaded pipe is threaded to the outer circumference of the vent pipe, and a dustproof net is connected to the inner wall of the threaded pipe.
[0010] As a preferred embodiment, four slide rails are embedded in the top of the loading and unloading box, and sliders are slidably connected to the slide rails.
[0011] As a preferred embodiment, the two sliders on opposite sides are connected to a cover, and the top of the cover is connected to an air intake pipe with a check valve.
[0012] As a preferred embodiment, multiple brake casters are installed at the bottom of the vehicle platform, and multiple L-shaped auxiliary plates are welded to the top of the vehicle platform.
[0013] In a preferred embodiment, the auxiliary plate is rotatably connected to a rotating plate via a rotating shaft, the top of the rotating plate is provided with a counterweight, and the top of the rotating plate is connected with multiple limiting frames for limiting the counterweight.
[0014] As a preferred embodiment, a servo motor that provides power to the rotating shaft is mounted on the top of the auxiliary plate.
[0015] As a preferred embodiment, a transverse electric push rod is installed at the bottom of the unloading hopper, and the movable part of the transverse electric push rod is connected and fixed to the sealing plate.
[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0017] In operation, the combined heat and power fuel loading and unloading device uses a fan to ventilate, reducing the possibility of impurities and dust escaping. When feeding the fuel into the loading and unloading box, the wire mesh filters the fuel in advance, and the dust screen filters the filtered impurities again. This double filtration not only reduces the filtration burden but also reduces the possibility of impurities and dust escaping. When unloading the fuel into the loading and unloading box, the fan's ventilation also reduces the possibility of dust escaping.
[0018] The combined heat and power fuel loading and unloading device places different numbers of counterweights on the rotating plate according to the different loading and unloading box loads to improve the overall stability. When unloading, the center of gravity may become unstable. At this time, the servo motor drives the rotating plate to rotate, adjusts the position of the counterweights and the plate, changes the overall center of gravity position, and improves stability.
[0019] This cogeneration fuel loading and unloading device can not only perform dust extraction and filtration, but also adjust the counterweight to improve stability. Attached Figure Description

[0029] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0030] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0031] The connection method can adopt existing methods such as bonding, welding, bolting, etc., depending on the actual needs. Techniques, methods and equipment known to those skilled in the art may not be discussed in detail. However, where appropriate, the techniques, methods and equipment should be regarded as part of the specification. The proportions of the components in the drawings are for reference only and can be adjusted to a certain extent according to the actual use.
[0032] Please see Figures 1 to 5 As shown, a combined heat and power (CHP) fuel loading and unloading device, in this embodiment, includes:
[0033] Car panel 1;
[0034] Assembly plate 2 is welded to the top of vehicle plate 1. The height of assembly plate 2 and the length of side support plate 4 are selected according to actual needs. Linear motors 3 are embedded in both sides of assembly plate 2. The moving part of linear motor 3 is fixedly connected to side support plate 4. The side of side support plate 4 is detachably connected to loading and unloading box 5 for loading and unloading cogeneration fuel.
[0035] An inclined filter frame 6 is detachably connected to the inner wall of the loading and unloading box 5. The top of the filter frame 6 is connected to a wire mesh 7 for filter support. An inclined unloading hopper 8 is embedded in one side of the loading and unloading box 5. The bottom of the unloading hopper 8 is provided with a discharge port. The position of the discharge port and the unloading hopper 8 is selected according to actual needs. A sealing plate 10 for blocking the discharge port is provided below the unloading hopper 8. A U-shaped limiting plate 9 for limiting the sealing plate 10 is connected to the bottom of the unloading hopper 8. A horizontal electric push rod 26 is installed at the bottom of the unloading hopper 8. The moving part of the horizontal electric push rod 26 is connected and fixed to the sealing plate 10. After feeding is completed, the movable box cover 18 is used to block and seal. The linear motor 3 is adjusted to change the height of the loading and unloading box 5 and push the whole to move so that the discharge port of the unloading hopper 8 is aligned with the receiving equipment. The horizontal electric push rod 26 is controlled to retract, so that the sealing plate 10 releases the blockage of the discharge port and the fuel falls with gravity.
[0036] A discharge plate 11 is rotatably connected to the side of the loading and unloading box 5 away from the discharge hopper 8. Multiple fans 12 are embedded in the side of the discharge plate 11. The fans 12 are dust-resistant fans. If filtration is required, dust filter bags can be installed on the side of the fans 12. An L-shaped ventilation pipe 13 is connected to the side of the fans 12. A threaded pipe 14 is threaded to the outer circumference of the ventilation pipe 13. A dustproof net is connected to the inner wall of the threaded pipe 14. During use, the fans 12 draw air. When feeding material into the loading and unloading box 5, the wire mesh 7 pre-filters the fuel, and the dustproof net filters the filtered impurities. The double filtration not only reduces the filtration burden but also reduces the possibility of impurities and dust escaping. When the loading and unloading box 5 discharges material, the fan 12 draws air, which also reduces the possibility of dust escaping.
[0037] Four slide rails 16 are embedded in the top of the loading and unloading box 5. The slide rails 16 are slidably connected to sliders 17. Two sliders 17 on opposite sides are connected to the box cover 18. The top of the box cover 18 is connected to an air inlet pipe 19 with a check valve.
[0038] To improve stability, multiple brake casters 20 are installed at the bottom of the platform 1, and multiple L-shaped auxiliary plates 21 are welded to the top of the platform 1. The positions of the multiple auxiliary plates 21 are staggered, so that the rotation of the outer rotating plate 22 does not affect the rotation adjustment of the inner rotating plate 22. The auxiliary plates 21 are rotatably connected to the rotating plate 22 via a rotating shaft. A counterweight 23 is set at the top of the rotating plate 22, and multiple limiting frames 24 for limiting the counterweight 23 are connected to the top of the rotating plate 22. A servo motor 25 that provides power to the rotating shaft is installed at the top of the auxiliary plates 21. During unloading, some of the servo motors 25 drive the rotating plate 22 to rotate, adjust the position of the counterweight 23 and the platform 1, change the overall center of gravity, and improve stability.
[0039] The linear motor 3, fan 12, servo motor 25, and transverse electric actuator 26 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0040] Working principle
[0041] In operation, the combined heat and power fuel loading and unloading device uses a blower 12 to draw air. When feeding the fuel into the loading and unloading box 5, the wire mesh 7 filters the fuel beforehand, and the dustproof net filters the filtered impurities. After feeding is completed, the movable box cover 18 is used to block and seal the fuel. The linear motor 3 is adjusted to change the height of the loading and unloading box 5, which pushes the whole unit to move so that the discharge port of the unloading hopper 8 is aligned with the receiving equipment. The horizontal electric push rod 26 is controlled to retract, so that the sealing plate 10 releases the blockage of the discharge port, and the fuel falls with gravity.
[0042] During unloading, some servo motors 25 drive the rotating plate 22 to rotate, adjust the position of the counterweight block 23 and the vehicle plate 1, change the overall center of gravity, and improve stability.
