Description

Technical Field

[0001] This utility model relates to the field of boiler automated packing technology, specifically to an automated boiler packing device. Background Technology

[0002] A boiler is a core energy conversion device that converts the chemical energy contained in fuels (such as coal, natural gas, oil, or biomass) into heat energy through combustion, and then transfers this heat energy to water to produce steam or high-temperature hot water at a certain pressure and temperature. As an indispensable "heart" of modern industrial systems and urban life, boilers provide steam and hot water to drive turbines in power plants, support production processes in many fields such as petrochemicals, textile printing and dyeing, and food processing, and are widely used in district heating.

[0003] Most products on the market solve the problem of automated boiler feeding through grates or augers. However, grate feeding systems have high production costs and too many mechanical components, making them unsuitable for small and medium-sized boilers. Auger feeding systems cannot solve the problems of coking and slag removal after the combustion of low-quality fuels. Auger feeding can only control the amount of feed by the speed of the auger, but too slow a speed can cause problems such as backfire in the hopper. Once a failure occurs, disassembly is complicated. The quality of fuels on the market varies greatly, and because the equipment on the market has extremely high requirements for fuel, the customer's costs are huge, and the equipment failure rate is very high. Therefore, we propose an automated boiler filling device. Utility Model Content

Except for the springs located on connecting rod three and the springs on the rearmost propulsion plate, the remaining springs are located between two adjacent propulsion plates, thereby enabling the piston to advance while keeping the cable taut.

[0011] Furthermore, the propulsion mechanism also includes a pulley and a spool. The pulley is rotatably connected to the lower rear side of the base plate via a rotating seat. A rotating shaft is rotatably connected between the inner walls of the left and right sides of the piston seat. A spool is fixedly sleeved in the middle of the rotating shaft.

[0012] Furthermore, a transition shaft is fixedly connected to the center of the rear side of the base plate, and the cable is slidably connected to the outer arc surface of the transition shaft to achieve a smooth transition of the cable.

[0013] Furthermore, it also includes a drive mechanism, which includes gear one, gear two, gear three, gear four and a motor. Gear one is fixedly sleeved on the right end of shaft one.

[0022] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This embodiment provides a technical solution: an automated boiler filling device, including a base 1 and a propulsion mechanism 5;

[0024] Base 1: A feeding pipe 2 is fixedly connected to the upper end of the base 1, a piston 4 is slidably connected inside the feeding pipe 2, and a piston seat 3 is fixedly connected to the rear end of the base 1.

[0025] The propulsion mechanism 5 includes a connecting plate 51, a propulsion assembly 53, a base plate 54, connecting rods 55, and fixed shafts 57. The connecting plate 51 is located on the inner front wall of the piston seat 3. The rear side of the connecting plate 51 has evenly distributed connecting rods 53. The rear side of the base plate 54 has symmetrically distributed fixed shafts 57. The rear ends of the two fixed shafts 57 are bolted to the front side of the rear cover of the piston seat 3. The front side of the base plate 54 has evenly distributed connecting rods 55. A mounting plate 9 is fixedly connected between the front ends of the connecting rods 55. The propulsion assembly 53 is evenly distributed between the connecting rods 53 and the mounting plate 9. The propulsion mechanism 5 also includes bolts 52, which are evenly distributed... The bolts 52 are placed on the front side of the connecting plate 51. The front side of the bolts 52 passes through the openings on the front side of the piston seat 3 and is threaded with nuts. The propulsion assembly 53 includes a propulsion plate 531, a connecting rod 532, and a sleeve 534. The rear side of the propulsion plate 531 is provided with evenly distributed connecting rods 532 and sleeves 534. The rear ends of the connecting rods 532 are slidably connected to the interior of the sleeves 534 adjacent to the frontmost propulsion plate 531. The rear ends of the connecting rods 532 of the rearmost propulsion plate 531 are slidably connected to the interior of the through holes of the mounting plate 9. Except for the connecting rods 532 of the frontmost and rearmost propulsion plates 531, the other connecting rods 532 are slidably connected to the adjacent sleeves 534 on the rear side. Inside the sleeve 534 of the push plate 531, the push assembly 53 also includes springs 533. Springs 533 are movably sleeved on the outside of connecting rod three and connecting rod one 532. The springs 533 on connecting rod three are located between connecting plate 51 and the foremost push plate 531. The springs 533 on connecting rod one 532 on the rearmost push plate 531 are located between the rearmost push plate 531 and the mounting plate 9. Except for the springs 533 on connecting rod three and the rearmost push plate 531, the remaining springs 533 are located between two adjacent push plates 531. When the motor 85 rotates in the reverse direction, the spool 58 releases the cable, and springs 53... 3. Reset, connecting rod 532 slides forward in the sleeve 534 adjacent to the rear push plate 531 and the through hole of the mounting plate 9 respectively (the rear ends of connecting rod 532 and connecting rod 3 can be threaded with anti-loosening bolts to prevent connecting rod 532 and connecting rod 3 from detaching from the rear push plate 531. The rear cover of piston seat 3 can be opened to remove the whole assembly of push plate 531, connecting rod 532 and sleeve 534, remove the anti-loosening bolts, and take out spring 533 for replacement to ensure the good elasticity of spring 533). The piston 4 is pushed forward by the connecting plate 51 to push the fuel inside the feeding pipe 2 into the combustion chamber, and at the same time scrapes off the fuel adhering to the inner wall of the feeding pipe 2.

[0026] The propulsion mechanism 5 also includes a pulley 56 and a spool 58. The pulley 56 is rotatably connected to the lower rear side of the base plate 54 via a rotating seat. A rotating shaft 6 is rotatably connected between the inner walls of the left and right sides of the piston seat 3. A spool 58 is fixedly sleeved in the middle of the rotating shaft 6. A cable is provided on the outside of the spool 58. The front end of the cable passes through the clearance holes in the middle of the base plate 54, the mounting plate 9, and the propulsion plate 531, and is then fixedly connected to the middle rear side of the connecting plate 51. The outside of the cable is slidably connected to the outer arc surface of the pulley 56. The middle rear side of the base plate 54 is fixedly connected to the pulley 56. The cable is connected to the transition shaft 7, and the cable is externally slidably connected to the outer arc surface of the transition shaft 7. When the cable is retracted, it drives the entire assembly of the connecting plate 51 and the piston 4 to slide backward inside the feeding pipe 2. The distance between the connecting plate 51 and the mounting plate 9 decreases. The connecting rod 532 slides backward inside the sleeve 534 adjacent to the rear push plate 531 and the through hole of the mounting plate 9, respectively. The spring 533 is compressed, and the reaction force generated by the spring 533 keeps the cable taut and prevents the cable from bending between the push plates 531. The piston 4 retracts.

[0027] The system also includes a drive mechanism 8, which comprises gear 1 81, gear 2 82, gear 3 83, gear 4 84, and a motor 85. Gear 1 81 is fixedly sleeved on the right end of rotating shaft 1 6. Rotating shaft 2 is rotatably connected to the right side wall of base 1. Gear 2 82 is fixedly connected to the right end of rotating shaft 2, and gear 3 83 is fixedly connected to the left end of rotating shaft 2. Motor 85 is fixedly connected to the bottom wall of base 1. Gear 4 84 is fixedly sleeved on the output shaft of motor 85. Gear 1 81 and gear 2 82 mesh with each other. The connection is made so that gears 3 (83) and 4 (84) are meshed. The input end of motor 85 is electrically connected to the output end of an external controller. When the output shaft of motor 85 rotates, it drives gear 4 (84) to rotate. Through the transmission of gears 1 (81), 2 (82), and 3 (83), it drives shaft 1 (6) to rotate. Shaft 1 (6) drives spool 58 to rotate. Spool 58 rotates and retracts the cable. The cable is guided by transition shaft 7 and pulley 56 and rewound to the outside of spool 58. When motor 85 rotates in the opposite direction, spool 58 releases the cable.

[0028] The working principle of the automated boiler filling device provided by this utility model is as follows: A hopper is provided at the upper end of the outer arc surface of the feeding pipe 2. Fuel enters the interior of the feeding pipe 2 from the hopper. The front end of the feeding pipe 2 is the combustion chamber. When this automated boiler filling device is in use, the output shaft of the motor 85 rotates (the motor 85 is a high-temperature resistant worm gear reducer motor with self-locking properties to prevent it from being driven to rotate by the drum 58, and it also has the characteristics of high temperature resistance to prevent overheating), which drives the gear 4 84 to rotate. Through the transmission of gear 1 81, gear 2 82 and gear 3 83, the rotating shaft 1 6 rotates (dust covers can be installed on the outside of gear 1 81 and gear 2 82 to achieve dust protection for gear 1 81 and gear 2 82). The rotating shaft 1 6 drives the drum 58 to rotate. The drum 58 rotates to retract the cable. The cable is guided by the transition shaft 7 and the pulley 56 to be rewound to the outside of the drum 58.

[0029] When the cable is retracted, the entire assembly consisting of the connecting plate 51 and the piston 4 slides backward inside the feeding pipe 2, reducing the distance between the connecting plate 51 and the mounting plate 9. The connecting rod 532 slides backward inside the sleeve 534 adjacent to the rear push plate 531 and the through hole of the mounting plate 9, respectively. The spring 533 is compressed, and the reaction force generated by the spring 533 keeps the cable taut, preventing the cable from bending between the push plates 531. The piston 4 retracts.

[0030] When motor 85 rotates in reverse, reel 58 releases the cable, spring 533 returns to its original position, and connecting rod 532 slides forward inside the sleeve 534 adjacent to the rear push plate 531 and through the mounting plate 9 respectively. (Both connecting rods 532 and 532 can be threaded with anti-loosening bolts to prevent them from detaching from the rear push plate 531. The rear cover of piston seat 3 can be opened to remove the assembly consisting of push plate 531, connecting rod 532, and sleeve 534. The anti-loosening bolts can be removed, and spring 533 can be replaced.) The piston 4 is pushed forward by the connecting plate 51 to push the fuel inside the feeding pipe 2 into the combustion chamber, and at the same time scrapes off the fuel adhering to the inner wall of the feeding pipe 2. The piston 4 is a hollow sleeve to prevent the fuel or ash in the combustion chamber from contacting the various parts of the propulsion assembly 53. The speed of the motor 85 is kept constant by controlling the motor 85 through an external controller. The length of the cable that the reel 58 releases or retracts can be adjusted by adjusting the running time of the motor 85, so as to realize the position control of the piston 4. The fuel can be delivered to the combustion chamber and the completely burned fuel can be pushed to the ash box or the area for storing waste residue.

[0031] It is worth noting that the motor 85 disclosed in the above embodiments can be an S-series high-temperature worm gear reducer, and the external controller controls the operation of the motor 85 using methods commonly used in the prior art.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
