TECHNICAL FIELD

[0001] The present application relates to the technical field of boiler slag discharge cleaning device, in particular to a modular dismountable slag discharge cleaning device for boiler. BACKGROUND

[0002] In the operation process of biomass boiler and other equipment, high-temperature slag will continuously accumulate in the bottom of the slag chute, and a special cleaning device is needed to remove it in time to prevent blockage and ensure continuous and stable operation of the equipment.

[0003] At present, the widely used mechanical cleaning device is an integral structure with the driving motor and the execution component such as the auger being welded or bolted, which has the following obvious defects in actual maintenance:

[0004] When the core conveying component of the cleaning device is worn out or damaged due to long-term contact with high-temperature and abrasive slag, it is extremely inconvenient to repair or replace due to its strong structural integrity and compact installation space. Maintenance personnel often need to remove the surrounding associated equipment first, or even completely remove the entire cleaning device from the slag discharge tank to repair the damaged internal components. This process not only is tedious and time-consuming, but also significantly prolongs the downtime of the equipment, seriously affecting the operation efficiency and economic benefits of the main machine.

[0005] Therefore, the cleaning device in the prior art has the problems of inconvenient maintenance and long downtime due to the strong structural integrity, and a new type of modular cleaning device for boiler is urgently needed to solve the problem. SUMMARY

[0006] In view of the above-mentioned defects of the prior art, the present application provides a modular dismountable slag discharge cleaning device for boiler, which can effectively solve the problems existing in the prior art.

[0007] To achieve the above purpose, the present application realizes the following technical solutions:

[0008] The present application provides a modular dismountable slag discharge cleaning device for boiler, which comprises a slag chute, a slag discharge tank is arranged at the bottom discharge port of the slag chute, a driving assembly is detachably connected to one side of the slag discharge tank through a quick-release locking mechanism, the driving assembly comprises a driving motor and a slag removal auger driven by the driving motor, a guide cleaning mechanism is arranged at the overhanging end of the slag removal auger, the guide cleaning mechanism is movably installed on the inner wall of the slag discharge tank, and is used for radially guiding and axially supporting the slag removal auger during dismounting, and simultaneously scraping the inner wall of the slag discharge tank, a support self-locking assembly is arranged on the guide cleaning mechanism, and is used for locking the overhanging end of the slag removal auger after the slag removal auger is installed in place, and the locking and unlocking operations of the quick-release locking mechanism and the locking and unlocking operations of the support self-locking assembly are triggered synchronously through the mounting and dismounting actions of the driving assembly along its axis.

[0010] Further, the protrusion is semicircular, and the curved surface thereof constitutes the curved surface one of the guide curved surfaces. When the driving assembly moves in the mounting direction, the locking block is driven to move away under the interaction of the guide curved surfaces, and when the locking groove moves to the position aligned with the locking block, the locking block is clamped into the locking groove under the action of the elastic member, thereby achieving locking.

[0011] Further, one end of the locking block in contact with the protrusion is provided with a curved surface two matching the curved surface one, and a locking flat surface used to abut against the side wall of the locking groove. When the driving assembly continues to move in the mounting direction to the unlocking station, the locking block moves away again and passes the sliding block. At this time, the driving assembly is reversely moved, the locking flat surface interacts with the side wall of the sliding block, the sliding block is driven to move radially until it enters the groove, and under the guidance of the side wall of the sliding block, the locking block is driven to move radially out of the locking groove, thereby achieving unlocking.

[0012] Further, the guide cleaning mechanism comprises a cross bar movably mounted on the inner wall of the slag discharge box and a scraper fixed to the cross bar with its side abutting against the inner wall of the slag discharge box. The overhanging end of the slag discharge auger is provided with a rotating bearing, the two sides of the rotating bearing are fixed with a push rod, and the cross bar is provided with a linkage adsorption part corresponding to the position of the push rod. When the driving assembly moves in the mounting direction, the push rod and the cross bar are adsorbed to each other through the linkage adsorption part, so as to push the cross bar and the scraper to move synchronously into the interior of the slag discharge box.

[0013] Further, the linkage adsorption part comprises a trapezoidal block provided on the cross bar and a trapezoidal groove provided on the push rod, and magnetic blocks are provided in the trapezoidal block and the trapezoidal groove.

[0015] Further, when the crossbar moves towards the inside of the slag discharge box, the V-shaped clamping slot of the rotating block opens towards the moving front, when the rotating block moves to the positioning groove at the front end of the rectangular block, under the action of gravity, the V-shaped clamping slot falls into the groove, and the rotating block is turned to be perpendicular to the moving groove, with the continuous movement of the crossbar, the rotating block is separated from the positioning groove, and is restored to the parallel state under the movement constraint, at this time, the opening direction of the V-shaped clamping slot is turned to the moving rear.

[0016] Further, when the crossbar moves to the maximum stroke, the rotating block moves to the end of the rectangular block, at this time, the short side of the V-shaped clamping slot slides off the rectangular block first, the rotating block is deflected again, so that the long side of the V-shaped clamping slot is clamped with the end edge of the rectangular block, thereby preventing the crossbar from moving reversely, and locking is realized.

[0017] Further, when it is necessary to unlock, a pushing force is applied to make the crossbar drive the rotating block to continue to move forward, the long side of the V-shaped clamping slot is separated from the rectangular block, the rotating block falls into the positioning groove at the rear end of the rectangular block and is turned to the state of opening towards the moving front, at this time, a pulling force is applied, the rotating block can pass through the rectangular block without obstruction, and unlocking is realized.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0045] The present application will be further described below with reference to the embodiments.

[0046] Embodiment 1

[0047] Reference Figures 1-7 For the first embodiment of the present application, a modularized and detachable slag removal and cleaning device for a boiler is provided, which comprises a slag falling chute 1, a slag removal box 11 is arranged at the bottom discharge port of the slag falling chute 1, a drive assembly 3 is detachably connected to one side of the slag removal box 11 through a quick release locking mechanism 2, the drive assembly 3 comprises a drive motor 31 and a slag removal auger 32 driven by the drive motor 31, wherein one end of the slag removal box 11 close to the drive assembly 3 is provided with a circular groove for moving the drive assembly 3, and the other end of the slag removal box 11 away from the drive assembly 3 is open for discharging waste slag.

[0048] Specifically, during the operation of the biomass boiler, a large amount of high-temperature slag is generated after the biomass fuel is burned, which falls into the slag falling chute 1 at the bottom of the boiler under the action of gravity, and enters the slag removal box 11 directly below the slag falling chute 1 through the opening at the bottom of the slag falling chute 1. The top of the slag removal box 11 is provided with a feed inlet in communication with the opening at the bottom of the slag falling chute 1 to receive the falling slag. After the drive motor 31 is started, the slag removal auger 32 is driven to rotate, and the auger blades push the slag accumulated at the bottom of the slag removal box 11 in the axial direction, and finally the slag is discharged from the discharge port at the end of the slag removal box 11, realizing continuous and automatic slag removal.

[0049] The existing cleaning device usually welds the driving motor 31 and the slagging auger 32 into one body, or fixes them on the side wall of the slag discharge box 11 through a plurality of bolts, and the integral mounting mode is extremely inconvenient to maintain and replace when the slagging auger 32 is abraded due to long-term conveying of abrasive slag, or is deformed and damaged due to blockage of foreign matters, the maintenance personnel need to use special tools to disassemble a large number of bolts, even need cutting operation, the operation space is limited, the process is tedious, which leads to significant extension of equipment downtime, seriously affects the continuous and stable operation of the boiler system, and the present application realizes quick mounting and dismounting of the driving assembly 3 by using the quick-release locking mechanism 2 in the cleaning device.

[0050] The quick-release locking mechanism 2 comprises a plug rod 21 fixed on the driving assembly 3, the plug rod 21 is provided with a lug 22 at the end, the plug rod 21 is movably provided with a sliding block 23, the sliding block 23 and the lug 22 form a locking groove 24, the lug 22 is provided with a groove 221 matching the size of the sliding block 23 on the side close to the plug rod 21, and a locking block 25 is movably arranged in the slag discharge box 11 through an elastic element, wherein the elastic element can be selected to use a spring, which is a conventional setting, and will not be described here, and the mating surfaces of the lug 22 and the locking block 25 are respectively provided with mutually matching guide curved surfaces.

[0051] The lug 22 is semicircular as a whole, the circular arc surface constitutes the curved surface one 222 in the guide curved surface, the end of the locking block 25 in contact with the lug 22 is provided with the curved surface two 251 matched with the curved surface one 222, and the locking flat surface used for abutting with the side wall of the locking groove 24.

[0052] Specifically, the plug rod 21 serves as a connection carrier, the lug 22 at the front end thereof and the movable sliding block 23 together constitute an execution component of the locking function, the sliding block 23 can slide radially on the plug rod 21, and forms the locking groove 24 for clamping when it is enclosed with the lug 22, and the groove 221 opened on the lug 22 provides a containing space for the radial movement of the sliding block 23 when it is unlocked.

[0053] The bottom of the sliding block 23 is elastically connected with the plug rod 21 body through a spring, the design of the spring provides the reset force required for the radial movement of the sliding block 23, and ensures that the sliding block 23 and the lug 22 have a stable initial relative position.

[0054] Wherein the pre-tightening force of the spring is precisely set, two key conditions need to be met at the same time, one is that in the locked state, the spring force needs to be sufficient to maintain the close enclosure of the slider 23 and the protrusion 22, to ensure the structural integrity of the locking groove 24, to prevent the accidental disengagement of the locking block 25 due to vibration or external force impact, the second is that in the unlocking process, when the locking plane of the locking block 25 extrudes the side wall of the slider 23, the spring force can be smoothly overcome, allowing the slider 23 to smoothly contract radially into the recess 221 of the protrusion 22, to make way for the disengagement of the locking block 25, this force balance design is the core of ensuring that the quick release locking mechanism 2 can reliably perform one-key locking and smooth unlocking.

[0055] When the drive assembly 3 moves in the installation direction, the locking block 25 is moved away under the interaction of the guide arc surfaces, and when the locking groove 24 moves to the position opposite to the locking block 25, the locking block 25 is clamped into the locking groove 24 under the action of the elastic element, realizing locking, when the drive assembly 3 continues to move in the installation direction to the unlocking station, the locking block 25 moves away again and passes the slider 23, at this time, the drive assembly 3 is moved in the reverse direction, the locking plane interacts with the side wall of the slider 23, driving the slider 23 to move radially until it enters the recess 221, and under the guidance of the side wall of the slider 23, the locking block 25 is driven to move radially out of the locking groove 24, realizing unlocking.

[0056] Specifically, when the drive assembly 3 moves in the installation direction, the arc surface one 222 of the protrusion 22 first contacts the arc surface two 251 of the locking block 25, under the interaction of the guide arc surfaces, the locking block 25 is extruded and overcomes the elastic force of the elastic element to move away to one side, making space for the passage of the protrusion 22 and the slider 23, when the locking groove 24 moves to the position opposite to the locking block 25, the locking block 25 is quickly reset under the action of the elastic element, its locking plane is clamped into the locking groove 24, at this time, a clear click sound will be accompanied, providing the operator with a clear auditory signal of installation in place, at this time, the operator immediately stops pushing the drive assembly 3, the installation process is completed, realizing the locking of the drive assembly 3.

[0057] It needs to be specially pointed out that the present application utilizes the axial reaction force of the slag cleaning auger 32 during work to enhance the locking reliability, when the slag cleaning auger 32 works, the waste slag is pushed away from the direction of the drive motor 31 to the slag discharge box 11, at this time, the entire drive assembly 3 is subjected to a reaction force, the force is directed to the drive motor 31 direction, acting on the drive assembly 3, instead of making the locking block 25 of the quick release locking mechanism 2 and the locking groove 24 combine more tightly, and making the V-shaped clamping groove 53 of the supporting self-locking assembly 5 and the rectangular block 52 clamping more firmly, forming a self-enhancing effect of the more pressure the tighter, that is, the present application combines mechanical design, physical limiting and specific operation sequence to realize convenient quick release, while fundamentally eliminating the possibility of accidental unlocking, ensuring the absolute reliability of operation.

[0058] When disassembly is required, the operator must consciously push the drive assembly 3 a short distance along the installation direction to the unlocking position. The locking block 25 is squeezed and pushed past the slider 23. At this time, the drive assembly 3 moves in the opposite direction, and the locking plane of the locking block 25 contacts and interacts with the side wall of the slider 23, driving the slider 23 to move radially until it is completely inserted into the groove 221 of the protrusion 22. During this process, the side wall of the slider 23 guides the locking block 25 to move radially away from the locking groove 24, thereby achieving rapid unlocking.

[0059] In summary, the present invention is equipped with a modular drive assembly 3 and a quick-release locking mechanism 2, which allows core components such as the slag cleaning auger 32 to be independently and quickly disassembled from the side wall of the slag discharge box 11. Maintenance does not require the removal of surrounding equipment or the entire device, thereby greatly shortening downtime and fundamentally solving the prominent problem of inconvenient maintenance of existing integrated cleaning devices.

[0060] Example 2

[0061] Reference Figures 8-15 The second embodiment of the present invention provides a modular disassembly and assembly slag removal and cleaning device for boilers, including a guide cleaning mechanism 4. The cantilever end of the slag removal auger 32 is provided with the guide cleaning mechanism 4. The guide cleaning mechanism 4 is movably installed on the inner wall of the slag removal box 11 and is used to provide radial guidance and axial support for the slag removal auger 32 during disassembly and assembly, and to simultaneously scrape the inner wall of the slag removal box 11.

[0062] The guiding cleaning mechanism 4 includes a crossbar 41 and a scraper 42. The crossbar 41 is movably installed on the inner wall of the slag discharge box 11, and the scraper 42 is fixed on the crossbar 41 with its side in contact with the inner wall of the slag discharge box 11. The cantilever end of the slag cleaning auger 32 is provided with a rotating bearing 43, and push rods 44 are fixed on both sides of the rotating bearing 43. The crossbar 41 is provided with a linkage adsorption part 6 corresponding to the position of the push rod 44. When the drive assembly 3 moves along the installation direction, the push rod 44 and the crossbar 41 are attracted to each other through the linkage adsorption part 6, thereby pushing the crossbar 41 and the scraper 42 to move synchronously into the slag discharge box 11.

[0063] The linkage adsorption unit 6 includes a trapezoidal block 61 disposed on the crossbar 41 and a trapezoidal groove 62 disposed on the push rod 44. Both the trapezoidal block 61 and the trapezoidal groove 62 are provided with magnetic blocks, and the two are attracted and fixed to each other by magnetic force.

[0064] Specifically, during the installation of the driving assembly 3, as the slag cleaning auger 32 extends into the slag discharge box 11, the push rod 44 fixed to the rotating bearing 43 at the end thereof gradually approaches the trapezoidal block 61 on the cross bar 41. When the two are close, the trapezoidal groove 62 and the trapezoidal block 61 are quickly and accurately aligned and tightly combined under the strong adsorption force of the magnetic block. This process automatically completes the butt joint of the overhanging end of the slag cleaning auger 32 and the guiding and cleaning mechanism 4. After successful butt joint, the driving assembly 3 is continuously pushed forward, and the push rod 44 will push the cross bar 41 and the scraper 42 fixed thereon to move into the interior of the slag discharge box 11 together. The cross bar 41 provides radial limiting for the overhanging end of the slag cleaning auger 32 during movement, preventing it from shaking and playing a radial guiding role.

[0065] Meanwhile, the close cooperation of the push rod 44 and the cross bar 41 together constitutes axial support for the overhanging end of the slag cleaning auger 32, effectively preventing it from sagging due to its own weight, ensuring coaxiality during installation and running stability. The scraper 42 fixed to the cross bar 41 has its edge closely attached to the inner wall of the slag discharge box 11 during synchronous movement, scraping off the residual slag attached to the inner wall, and achieving automatic cleaning.

[0066] The guiding and cleaning mechanism 4 is provided with a supporting and locking assembly 5 for locking the overhanging end of the slag cleaning auger 32 after installation. The locking and unlocking operations of the quick-release locking mechanism 2 and the locking and unlocking operations of the supporting and locking assembly 5 are triggered synchronously through the installation and disassembly actions of the driving assembly 3 along its axis.

[0067] The supporting and locking assembly 5 includes a rotating block 51 and a rectangular block 52. The rotating block 51 is movably connected to the cross bar 41 through a rotating shaft. The rotating block 51 has a V-shaped clamping groove 53 at one end. The rectangular block 52 is fixedly installed on the inner wall of the slag discharge box 11. The inner wall of the slag discharge box 11 is also provided with a moving groove 111 for the movement of the rotating block 51 along with the cross bar 41. Positioning grooves 112 are arranged at both ends of the rectangular block 52 along the path of the moving groove 111. The rotating block 51 can be converted between the parallel and perpendicular directions to the moving direction under the action of external force and its own gravity, and through the cooperation of the V-shaped clamping groove 53 and the rectangular block 52, the automatic locking and unlocking of the cross bar 41 is realized.

[0068] Specifically, during the installation of the driving assembly 3, the crossbar 41 drives the rotating block 51 to move towards the inside of the slag bin 11. In the initial state, the V-shaped clamping groove 53 of the rotating block 51 is open towards the moving front. When the rotating block 51 moves to the positioning groove 112 at the front end of the rectangular block 52, under the action of gravity, the V-shaped clamping groove 53 falls into the groove, and the rotating block 51 is turned from a state parallel to the moving groove 111 to a state perpendicular to the moving groove 111. As the crossbar 41 continues to move, the rotating block 51 is disengaged from the positioning groove 112 and restored to a parallel state under the constraint of the moving groove 111. Notably, this process automatically changes the opening direction of the V-shaped clamping groove 53 to be towards the moving rear, preparing for the final locking. When the crossbar 41 moves to the maximum stroke (i.e., the slagging auger 32 is installed in place), the rotating block 51 is just moved to the end of the rectangular block 52. At this time, the short side of the V-shaped clamping groove 53 slides off the rectangular block 52 first, causing the rotating block 51 to deflect again, so that the long side of the V-shaped clamping groove 53 forms a firm clamping with the end edge of the rectangular block 52, thereby mechanically preventing the reverse movement of the crossbar 41, achieving automatic locking of the overhanging end of the slagging auger 32.

[0069] When the crossbar 41 moves towards the inside of the slag bin 11, the V-shaped clamping groove 53 of the rotating block 51 is open towards the moving front, when the rotating block 51 moves to the positioning groove 112 at the front end of the rectangular block 52, under the action of gravity, the V-shaped clamping groove 53 falls into the groove, and the rotating block 51 is turned to a state perpendicular to the moving groove 111, as the crossbar 41 continues to move, the rotating block 51 is disengaged from the positioning groove 112 and restored to a parallel state under the constraint of the moving, at this time the opening direction of the V-shaped clamping groove 53 is changed to be towards the moving rear, when the crossbar 41 moves to the maximum stroke, the rotating block 51 moves to the end of the rectangular block 52, at this time, the short side of the V-shaped clamping groove 53 slides off the rectangular block 52 first, the rotating block 51 deflects again, so that the long side of the V-shaped clamping groove 53 forms a clamping with the end edge of the rectangular block 52, thereby preventing the reverse movement of the crossbar 41, achieving locking.

[0070] When it is necessary to unlock, a pushing force is applied to make the crossbar 41 drive the rotating block 51 to continue to move forward, the long side of the V-shaped clamping groove 53 is separated from the rectangular block 52, the rotating block 51 falls into the positioning groove 112 at the rear end of the rectangular block 52 and is turned to a state with the opening towards the moving front. At this time, a pulling force is applied, and the rotating block 51 can pass through the rectangular block 52 without obstruction, achieving unlocking.

[0071] The application is provided with a guiding and cleaning mechanism 4 and a supporting and self-locking assembly 5 which are linked with the dismounting action, through automatically completing accurate guiding and reliable supporting during installation, synchronously releasing locking and resetting during dismounting, the alignment, fixing and separation operations during the whole maintenance process become simple and direct, the maintenance process is greatly simplified, the technical requirements for the operator are reduced, thereby effectively solving the technical problems of complicated, time-consuming and laborious maintenance operation of the existing device.

[0072] Specifically, when the driving assembly 3 needs to be dismounted, the operator only needs to apply a slight pushing force to the driving assembly 3, so that the cross rod 41 drives the rotating block 51 to continue to move forward by a small distance, at this time, the long side of the V-shaped clamping groove 53 is separated from the end edge of the rectangular block 52, the rotating block 51 falls into the positioning groove 112 at the rear end of the rectangular block 52, under the action of gravity, the rotating block 51 falls into the groove and turns to the state of opening towards the moving front, at this time, the driving assembly 3 is pulled in the reverse direction, the rotating block 51 can pass through the rectangular block 52 without obstruction, and automatic unlocking is realized. The whole locking and unlocking process is triggered and automatically completed by the axial movement of the driving assembly 3, without any additional operation.

[0073] The traditional maintenance needs multiple people to cooperate, uses multiple tools, and has complicated and time-consuming steps, while the present scheme only needs a single person to simply push in to complete the installation and locking, or to slightly push and then pull out to complete the unlocking and dismounting, two core steps, which shortens the maintenance work which may take several hours to several minutes, truly realizes fast maintenance, and significantly reduces the labor intensity and downtime.
