Description

Technical Field

[0001] This utility model relates to the field of water recirculation furnace technology, and in particular to a water recirculation furnace feeding mechanism. Background Technology

[0002] A waste heat recovery boiler, also known as a waste heat recovery boiler or a hot water boiler, is a type of boiler that uses the waste heat of flue gas to heat water. The waste heat recovery boiler uses a specific heat exchange device to transfer the waste heat in the flue gas to the water entering the boiler, thereby raising the water temperature and achieving the purpose of heating or process heat, thus realizing energy saving and efficient utilization. Among them, fuel-type waste heat recovery boilers use fuel (such as coal, oil, gas, biomass, etc.) as a heat source to generate heat energy through combustion.

[0003] In the prior art, when fuel-type reclaimed water furnaces use a hoist to lift and feed fuel, the opening at the hopper discharge point is fixed. When the fuel has a certain moisture content, such as biofuel, the feeding speed is easily too fast, causing the material to accumulate in the hopper or the casing. In more serious cases, backflow at the discharge port, overload of the drive motor, or even chain breakage may occur. Therefore, a reclaimed water furnace feeding mechanism is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a feeding mechanism for a recycle furnace to address the aforementioned technical problems and achieve adjustable feeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding mechanism for a water recirculation furnace, comprising:

[0007] The elevator body has a hopper fixedly connected to the top of its lower part. The inner cavity of the hopper is provided with two movable baffles. A top plate is fixedly connected to one side of the baffles, and a fixed seat is fixedly connected to the outer side of the top plate. A connecting block is provided in the inner cavity of the fixed seat.

[0008] Drive unit one is fixedly installed on the outer wall of the hopper, and the output shafts at both ends of drive unit one are provided with screws.

[0009] In a preferred embodiment of the recycle furnace feeding mechanism provided by this utility model, the two baffles are symmetrically inclined, and the two top plates are respectively fixed to the opposite sides of the two baffles.

[0010] In a preferred embodiment of the recycle furnace feeding mechanism provided by this utility model, the connecting block is movably connected to the inner cavity of the corresponding fixed seat.

[0011] In a preferred embodiment of the recycle furnace feeding mechanism provided by this utility model, the drive unit is fixedly installed on the outer wall of the hopper via a mounting frame. Specifically, the drive unit is a dual-axis motor, and the output shafts at both ends of the motor are respectively connected to two screw drives.

[0012] In a preferred embodiment of the recycle furnace feeding mechanism provided by this utility model, the surface of the screw is threadedly connected to the corresponding connecting block, two ear plates are fixedly connected to one side of the hopper, and one end of the screw is movably connected to the corresponding ear plate.

[0013] In a preferred embodiment of the recycle furnace feeding mechanism provided by this utility model, a connecting column is fixedly connected to the inner cavity of the fixed base, and the surface of the connecting column is slidably connected to the corresponding connecting block.

[0014] In a preferred embodiment of the recirculating furnace feeding mechanism provided by this utility model, a spring is sleeved on the surface of the connecting column, one end of the spring is fixedly connected to the fixed seat, and the other end of the spring is fixedly connected to the connecting block.

[0015] In a preferred embodiment of the recycle furnace feeding mechanism provided by this utility model, a second drive unit is fixedly installed on both sides of the inner cavity of the hopper. The second drive unit is specifically a motor, and the output shaft of the second drive unit extends movably through to the outside of the hopper and is connected to a cam for transmission.

[0016] In a preferred embodiment of the recycle furnace feeding mechanism provided by this utility model, a horizontal plate is movably connected to the top of the cam, and a plurality of protruding columns are fixedly connected to the top of the horizontal plate.

[0017] In a preferred embodiment of the recycle furnace feeding mechanism provided by this utility model, the horizontal plate is slidably connected to the outer wall of the hopper and cannot be detached.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a recycle furnace feeding mechanism that, when feeding fuel, can adjust the position of two baffles according to the fuel condition, thereby changing the distance between the two baffles and adjusting the amount of fuel discharged from the hopper. The amount of fuel discharged can be dynamically adjusted according to the fuel characteristics to adapt to the supply needs of different types of fuel, avoiding over- or under-discharge. Flexible switching can be achieved by adjusting the baffle spacing, improving the versatility of the lifting system and ensuring maximum combustion efficiency.

[0020] The present invention provides a feeding mechanism for a recycle furnace. When the baffle is guiding the material, the second drive unit can be opened. The second drive unit can drive the convex column to rise and fall, thereby lifting the top plate and the baffle upwards and reciprocating. This increases the speed at which fuel falls from the hopper and reduces the risk of "bridging" caused by material accumulation at the inlet, thereby reducing residue caused by blockage.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A feeding mechanism for a recycle furnace includes a hoist body 1, a hopper 2 fixedly connected to the top of the hoist body 1 at its lowest point, two movable baffles 3 provided in the inner cavity of the hopper 2, a top plate 4 fixedly connected to one side of the baffle 3, a fixed seat 5 fixedly connected to the outer side of the top plate 4, and a connecting block 6 provided in the inner cavity of the fixed seat 5; a drive unit 7 fixedly installed on the outer wall of the hopper 2, and screws 9 provided on the output shafts at both ends of the drive unit 7.

[0032] Preferably, the two baffles 3 are symmetrically inclined to form a "V"-shaped feeding channel. The fuel's own weight guides the material towards the center, reducing material adhesion to the hopper wall and improving feeding uniformity. Two top plates 4 are fixed to opposite sides of the two baffles 3. When the baffles 3 move within the hopper 2, the top plates 4 can block the gap between the baffles 3 and the hopper 2, preventing fuel from accidentally entering. They also increase the stress-bearing area, improving the baffles 3's impact resistance and effectively dispersing stress, preventing deformation of the baffles 3 due to material impact. The connecting block 6 is movably connected to the inner cavity of the corresponding fixed seat 5. The drive unit 7 is fixedly installed on the outer wall of the hopper 2 via a mounting bracket. The drive unit 7 is specifically a dual-axis motor, realizing the feeding... Symmetrical adjustment of material quantity ensures symmetrical flow regulation and avoids fuel deviation. The output shafts at both ends are respectively connected to two screws 9. The surface of the screws 9 is threadedly connected to the corresponding connecting block 6. Two ear plates 8 are fixedly connected to one side of the hopper 2. One end of the screw 9 is movably connected to the corresponding ear plate 8. A connecting column 10 is fixedly connected to the inner cavity of the fixed seat 5. The surface of the connecting column 10 is slidably connected to the corresponding connecting block 6. The connecting column 10 serves as a guide shaft, restricting the rotational freedom of the connecting block 6 and ensuring that the baffle 3 can still move vertically when it moves. A spring 11 is sleeved on the surface of the connecting column 10. One end of the spring 11 is fixedly connected to the fixed seat 5, and the other end of the spring 11 is fixedly connected to the connecting block 6.

[0033] Preferably, a second drive unit 12 is fixedly installed on both sides of the inner cavity of the hopper 2. The second drive unit 12 is specifically a motor. The output shaft of the second drive unit 12 extends movably through to the outside of the hopper 2 and is connected to a cam 13. A horizontal plate 14 is movably connected to the top of the cam 13. Several protruding columns 15 are fixedly connected to the top of the horizontal plate 14. The protruding columns 15 realize dynamic unblocking of the hopper 2, eliminate the risk of material blockage, and ensure continuous operation of the system. The horizontal plate 14 is slidably connected to the outer wall of the hopper 2 and cannot be separated, ensuring the verticality of the lifting action and avoiding mechanical interference caused by lateral offset. The horizontal plate 14 is prevented from detaching from the hopper 2 by limiting structures such as chutes and blocks, ensuring that the lifting stroke of the protruding columns 15 is controllable.

[0034] The operation of the feeding mechanism for a reclaimed water furnace provided by this utility model is as follows: Fuel is dropped from the hopper 2 to the top of the elevator body 1, and then the elevator body 1 lifts the fuel to realize the feeding operation of the reclaimed water furnace. When the hopper 2 feeds the fuel, the distance between the two baffles 3 can be adjusted according to the properties of the fuel. The first drive unit 7 is activated, and the first drive unit 7 drives the two screws 9 to rotate. The screws 9 drive the connecting block 6, connecting column 10, fixed seat 5, top plate 4 and baffles 3 to move. The two baffles 3 move towards each other or away from each other, thereby changing the distance between the two baffles 3 to adapt to different properties of fuel. When the fuel passes through the inner cavity of the hopper 2, the second drive unit 12 is activated, and the second drive unit 12 drives the cam 13 to rotate. Since the cam 13 is an eccentric wheel, when the cam 13 rotates, it will push the horizontal plate 14 and the convex column 15 to reciprocate up and down. The convex column 15 repeatedly lifts the top plate 4 and resets under the action of the spring 11, so that the baffles 3 and the top plate 4 can dynamically feed the fuel.
