Description

Technical Field

[0001] This invention relates to the field of slag fixation and treatment technology, and in particular to a slag fixation and treatment device for boilers. Background Technology

[0002] A boiler is a device that uses heat within its casing to provide hot water. The hot water or steam produced can directly provide the necessary heat energy for industrial production and daily life. This type of equipment can directly convert the thermal energy of fuel into thermal energy to supply industrial production or people's daily lives. Simultaneously, it can also convert thermal energy into mechanical energy through a steam power unit, or convert mechanical energy into electrical energy through a generator.

[0003] In the daily use of small boilers, a large amount of combustion waste is generated, requiring regular cleaning of the slag that easily adheres to the inner walls. However, small boilers come in various diameters, and for various reasons, the cleaning problem of small boilers is becoming increasingly important. Although some small boilers are equipped with slag removal devices, these devices often cannot be customized according to the size and shape of different boilers, resulting in them not fitting tightly against the inner wall of the boiler. This makes it difficult to completely remove the slag, affecting the cleaning efficiency of the boiler.

[0004] Currently, we still need workers to perform manual cleaning regularly, a process that is both time-consuming and labor-intensive, and the existing cleaning procedures are also quite complex. These factors further reduce the practicality of the boiler and affect the equipment's operating efficiency. Therefore, the demand for a cleaning device for small boilers is growing.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides a boiler slag fixing and treatment device, which includes a limit adjustment unit 100 and a slag removal unit 200. The rotation of the dual drive component 101 pushes the bottom extension component 202 to extend and open the slag removal component 203 in all directions, which is convenient for cleaning the inner wall of boilers of various sizes. The positioning clamping component 201 provides support for the limit adjustment unit 100 and positions the positioning clamping component 201 in the fixed state to maintain stability and prevent it from rotating with the dual drive component 101.

[0032] Specifically, the limit adjustment unit 100 includes a dual drive assembly 101, four sets of limit assemblies 102 disposed at the bottom of the dual drive assembly 101, and a moving assembly 103 disposed in the middle of the limit assembly 102.

[0033] The slag removal unit 200 includes a positioning clamping component 201 fixedly connected to the bottom of the limiting component 102, four sets of extension components 202 disposed at the bottom of the positioning clamping component 201, and a slag removal component 203 hinged to the side wall of the extension component 202.

[0034] In summary, this invention, by setting up a limit adjustment unit and a slag removal unit, rotates the dual drive assembly to push the extension assembly downward, causing the slag removal assembly to open and increase the contact range, facilitating the cleaning of boilers of different diameters. Pressing down on the positioning clamping assembly fixes the whole assembly, while simultaneously positioning the limit adjustment unit and ensuring the stability of the fixed state of the positioning clamping assembly. Sliding down on the dual drive assembly squeezes the limit assembly to release the locking limit on the moving assembly. Rotating the dual drive assembly again causes the moving assembly to rotate and move downward under the thread limit of the positioning clamping assembly, allowing the slag removal assembly at the bottom to rotate downward and scrape the slag adhering to the inner wall of the boiler. At the same time, the threaded locking state of the inner screw maintains the stability of the extension assembly after it is deployed.

[0035] Example 2

[0036] Reference Figures 1-7 This is the second embodiment of the present invention. This embodiment provides a boiler slag fixing and treatment device, which includes a limit adjustment unit 100 and a slag removal unit 200. The rotation of the dual drive component 101 pushes the bottom extension component 202 to extend and open the slag removal component 203 in all directions, which is convenient for cleaning the inner wall of boilers of various sizes. The positioning clamping component 201 provides support for the limit adjustment unit 100 and positions the positioning clamping component 201 in the fixed state to maintain stability and prevent it from rotating with the dual drive component 101.

[0037] Specifically, the limit adjustment unit 100 includes a dual drive assembly 101, four sets of limit assemblies 102 disposed at the bottom of the dual drive assembly 101, and a moving assembly 103 disposed in the middle of the limit assembly 102.

[0038] The slag removal unit 200 includes a positioning clamping component 201 fixedly connected to the bottom of the limiting component 102, four sets of extension components 202 disposed at the bottom of the positioning clamping component 201, and a slag removal component 203 hinged to the side wall of the extension component 202.

[0039] Furthermore, the dual drive assembly 101 includes a drive ring 101a, a plurality of drive columns 101b fixedly connected to the outer wall of the drive ring 101a, four drive rods 101c fixedly connected to the inner wall of the drive ring 101a, a limiting ring 101d fixedly connected to the inner wall of the four drive rods 101c, four compression plates 101e fixedly connected to the bottom of the limiting ring 101d, and a compression ring 101f fixedly connected to the bottom of the limiting ring 101d.

[0040] Furthermore, the limiting assembly 102 includes a limiting sleeve 102a, a snap-fit ​​limiting sleeve 102b movably connected to the top of the limiting sleeve 102a, a snap-fit ​​telescopic rod 102c movably connected to the top of the snap-fit ​​limiting sleeve 102b, a telescopic plate 102d fixedly connected to the top of the snap-fit ​​telescopic rod 102c, a telescopic spring 102e fixedly connected to the inner wall of the telescopic plate 102d, and a compression telescopic block 102f fixedly connected to one end of the telescopic spring 102e.

[0041] Furthermore, the moving assembly 103 includes a moving rod 103a, an external threaded surface 103b disposed in the middle of the moving rod 103a, four sets of extrusion limiting grooves 103c disposed in the top of the moving rod 103a, an internal threaded surface 103d disposed in the middle of the inner wall of the moving rod 103a, a push groove 103e disposed in the top of the moving rod 103a, a first smooth surface 103f disposed in the top of the moving rod 103a, and a second smooth surface 103g disposed in the bottom of the moving rod 103a.

[0042] Preferably, by gripping the drive column 101b, the drive ring 101a is rotated. The limiting sliding grooves 202i at the top of the four sets of drive rods 101c fixedly connected to the inner wall of the drive ring 101a are engaged, causing the internal thread rods 202g to rotate with the drive ring 101a. The threaded surface at the bottom of the internal thread rod 202g moves downward under the limitation of the internal threaded surface 103d in the middle of the inner wall of the moving rod 103a. The four sets of pressing limiting grooves 103c at the top of the moving rod 103a... The part is limited by the extrusion telescopic block 102f, preventing the moving rod 103a from rotating with the internal thread rod 202g. The internal thread rod 202g moves to contact the top of the bearing 202f, pushing the extrusion moving disk 202c fixedly connected to the bottom to slide downward. The extrusion bottom fixedly connected sets of return springs 202e retract, and the four sets of sliding limit blocks 202b are fixedly connected to the outer wall of the extrusion moving disk 202c and are located in the four sets of limit slide grooves 202d on the inner wall of the moving sleeve 202a to extrude. The sliding of the movable disk 202c is limited. The limiting collar 201a slides downward following the four sets of fixedly connected sliding limiting blocks 202b. The lifting push plate 203i fixedly connected to the outer wall of the limiting collar 201a pushes the four sets of hinged push plates 203h to rotate. The side wall of the sliding column 203c slides forward slightly below the hinged push plates 203h. The limiting slide frame 203b at the bottom limits the sliding column 203c on the inner wall. The limiting base 203f and two... The limiting slide plate 203g limits the vertical movement of the sliding column 203c, keeping the sliding column 203c in a horizontal direction and moving outward inside the limiting slide frame 203b. The large length of the extension block 203d can keep the slag removal knife 203e in contact with the smaller diameter boiler inner wall when the sliding column 203c retracts, which is convenient for adapting to boilers of various diameters. After the sliding column 203c pushes the fixedly connected slag removal knife 203e to maintain a tight contact with the boiler inner wall, the drive ring 101a stops rotating.

[0043] Furthermore, the positioning and clamping assembly 201 includes a limiting collar 201a, four sets of fixing crossbars 201b fixedly connected to the side wall of the limiting collar 201a, positioning pins 201c symmetrically arranged at one end of the two sets of fixing crossbars 201b, two sets of first clamping plates 201d symmetrically arranged on both sides of the fixing crossbars 201b, a compression clamping plate 201e arranged on one side of the first clamping plate 201d, several sets of compression springs 201f fixedly connected to the side wall of the compression clamping plate 201e, and a second clamping plate 201g fixedly connected to one end of the compression springs 201f.

[0044] Furthermore, the extension assembly 202 includes a movable sleeve 202a, four sets of sliding limit blocks 202b fixedly connected to the inner wall of the movable sleeve 202a, a pressing movable disk 202c fixedly connected to the inner wall of the four sets of sliding limit blocks 202b, four sets of limiting slide grooves 202d disposed on the inner wall of the movable sleeve 202a, several sets of return springs 202e fixedly connected to the bottom of the pressing movable disk 202c, a bearing 202f fixedly connected to the top of the pressing movable disk 202c, an internal thread rod 202g disposed on the top of the pressing movable disk 202c, a smooth rod 202h disposed on the top of the internal thread rod 202g, and a limiting slide groove 202i disposed on the top of the smooth rod 202h.

[0045] Furthermore, the slag removal assembly 203 includes a fixed collar 203a, four sets of limiting slide frames 203b fixedly connected to the outer wall of the fixed collar 203a, a sliding column 203c disposed on the top of the limiting slide frame 203b, an extension block 203d fixedly connected to one side of the sliding column 203c, a slag removal knife 203e fixedly connected to one side of the extension block 203d, a limiting base plate 203f fixedly connected to the bottom of the sliding column 203c, two sets of limiting slide pieces 203g disposed on the top of the limiting slide frame 203b, four sets of push plates 203h symmetrically disposed on both sides of the sliding column 203c, and a lifting push plate 203i hinged to one end of the push plate 203h.

[0046] Preferably, by holding the drive column 101b and pressing down on the drive ring 101a, the drive ring 101a moves downward under the limitation of the four sets of drive rods 101c fixedly connected at the bottom and the limiting sliding groove 202i at the top of the smooth rod 202h. When the four sets of drive rods 101c move to contact the compression telescopic block 102f, the arc-shaped surface at the bottom of the drive rod 101c presses against the arc-shaped surface at the top of the matching compression telescopic block 102f, causing the compression telescopic block 102f to press against the telescopic spring 102e fixedly connected to the side wall, causing the compression telescopic block 102f to move and retract into the telescopic sleeve 10. Inside 2d, until the four sets of drive rods 101c are fully inserted into the bottom of the push groove 103e at the top of the moving rod 103a, the squeeze ring 101f contacts the top of the telescopic sleeve 102d, pushing the snap-fit ​​telescopic rod 102c fixedly connected to the bottom of the telescopic sleeve 102d downward to retract into the snap-fit ​​limiting sleeve 102b. The drive ring 101a is rotated again to drive the moving rod 103a to rotate, so that the moving rod 103a follows the rotation and rotates downward under the threaded connection of the limiting sleeve 201a, driving the slag removal knife 203e fixedly connected to the bottom to rotate and scrape the slag on the inner wall of the boiler.

[0047] Furthermore, the drive rod 101c is adapted to the compression plate 101e, the compression retaining ring 101f is set on the top of the compression telescopic rod 102c, the inner wall of the compression telescopic block 102f is set as an arc surface, the outer wall of the compression plate 101e is set as an arc surface, and the arc surface of the inner wall of the compression telescopic block 102f is adapted to the arc surface of the outer wall of the compression plate 101e.

[0048] Furthermore, the extrusion limiting groove 103c is adapted to the extrusion clamping plate 101e, the extrusion limiting groove 103c is adapted to the extrusion telescopic block 102f, the extrusion limiting groove 103c is set on the side wall of the first smooth surface 103f, and the bottom of the limiting sleeve 102a is fixedly connected to the top of the fixed crossbar 201b.

[0049] Furthermore, the limiting sliding groove 202i is disposed on the outer wall of the second smooth surface 103g, the extrusion moving disk 202c is slidably connected to the inner sliding groove of the second smooth surface 103g, the return spring 202e is fixedly connected to the bottom of the moving rod 103a, the fixing collar 203a is fixedly connected to the second smooth surface 103g at the bottom of the moving rod 103a, the limiting sliding frame 203b is adapted to the sliding column 203c, the push plate 203h is hinged to the sliding column 203c, the limiting sliding piece 203g is fixedly connected to the side wall of the sliding column 203c, one side of the lifting push plate 203i is fixedly connected to the outer wall of the moving sleeve 202a, and the moving sleeve 202a is slidably connected to the second smooth surface 103g.

[0050] It should be noted that the four sets of compression clamping plates 101e are arranged in a 90-degree array. The first clamping plate 201d, the compression clamping plate 201e, and the second clamping plate 201g are all set in an arc shape. The inner wall of the limiting collar 201a is provided with a threaded surface that matches the external threaded surface 103b in the middle of the moving rod 103a. The outer wall of the compression clamping plate 201e is set in an arc shape, and the positioning pin 201c is set in a cylindrical shape.

[0051] In use, after the positioning clamping assembly 201 positions and fixes the boiler, the slag removal unit 200 is placed on top of the boiler. After the positioning clamping assembly 201 positions the entire device, the four sets of fixed crossbars 201b are pressed down. When the positioning clamping assembly 201 moves downward, the positioning pin 201c is inserted into the hanging ears on both sides of the small boiler. The arc-shaped surface at the bottom of the squeezing clamping plate 201e is squeezed to one side by the top of the boiler, and the pushing force is applied to several sets of squeezing springs 201f to deform and contract. When the positioning pin 201c is completely inserted into the bottom of the hanging ear, the pushing of the four sets of fixed crossbars 201b is stopped. The reaction force generated by several sets of squeezing springs 201f clamps the inner wall of the boiler. Several sets of friction blocks are provided on the inner walls of the squeezing clamping plate 201e and the two sets of first clamping plates 201d to enhance the friction with the boiler and form a double clamping positioning and fixation, increasing the overall stability.

[0052] Rotating the dual drive assembly 101 adjusts the contact between the slag removal assembly 203 and the boiler inner wall. By gripping the drive column 101b, the drive ring 101a rotates. The limiting sliding groove 202i at the top of the four sets of drive rods 101c fixedly connected to the inner wall of the drive ring 101a is in a snap-fit ​​state, causing the internal thread rod 202g to rotate with the drive ring 101a. The threaded surface at the bottom of the internal thread rod 202g moves downward under the limitation of the internal threaded surface 103d in the middle of the inner wall of the moving rod 103a. The four sets of extrusion limiting grooves 103c at the top of 03a are limited by the extrusion telescopic block 102f, preventing the moving rod 103a from rotating with the internal thread rod 202g. The internal thread rod 202g moves to contact the top of the bearing 202f, pushing the extrusion moving disk 202c fixedly connected to the bottom to slide downward. The extrusion moving disk 202c fixedly connected to the bottom retracts, and the four sets of sliding limiting blocks 202b are fixedly connected to the outer wall of the extrusion moving disk 202c and are located on the inner wall of the moving sleeve 202a. The limiting slide groove 202d limits the sliding of the extrusion moving disc 202c. The limiting collar 201a slides downward with the four sets of fixedly connected sliding limiting blocks 202b. The lifting push plate 203i fixedly connected to the outer wall of the limiting collar 201a pushes the four sets of hinged push plates 203h to rotate. The side wall of the sliding column 203c slides forward slightly below the hinged push plate 203h. The limiting slide frame 203b at the bottom limits the sliding column 203c on the inner wall. The limiting base plate is fixedly connected to the bottom of the sliding column 203c. 203f and two sets of limiting slide plates 203g limit the vertical movement of the sliding column 203c, keeping the sliding column 203c in a horizontal direction and moving outward inside the limiting slide frame 203b. The large length of the extension block 203d can keep the slag removal knife 203e in contact with the smaller diameter boiler inner wall when the sliding column 203c retracts, which is convenient to adapt to boilers of various diameters. After the sliding column 203c pushes the fixedly connected slag removal knife 203e to maintain a tight contact with the boiler inner wall, the drive ring 101a stops rotating.

[0053] After completing the slag removal from the boiler inner wall, hold the drive column 101b and press the drive ring 101a downwards. This causes the drive ring 101a to move downwards under the limiting sliding groove 202i at the top of the smooth rod 202h, where the four sets of drive rods 101c are fixedly connected at the bottom. When the four sets of drive rods 101c move to contact the extrusion block 102f, the arc-shaped surface at the bottom of the drive rod 101c presses against the arc-shaped surface at the top of the extrusion block 102f, causing the extrusion block 102f to press against the telescopic spring 102e fixedly connected to the side wall. This causes the extrusion block 102f to move and retract into the telescopic sleeve 102d until the four sets of drive rods 101c are fully inserted into the bottom of the pushing groove 103e at the top of the moving rod 103a, thus securing the extrusion block. Ring 101f contacts the top of telescopic sleeve 102d, pushing the snap-fit ​​telescopic rod 102c, which is fixedly connected to the bottom of telescopic sleeve 102d, downward to retract into the snap-fit ​​limiting sleeve 102b. Then, the driving ring 101a rotates again, causing the moving rod 103a to rotate, and the moving rod 103a rotates with it. Under the threaded connection of the limiting sleeve 201a, it rotates and moves downward, causing the slag removal knife 203e, which is fixedly connected to the bottom, to rotate and scrape the slag on the inner wall of the boiler. At the same time, under the threaded connection of the limiting sleeve 201a, it is driven downward to completely scrape the side wall of the boiler. Under the locking action of the internal threaded rod 202g on the internal threaded surface 103d, the slag removal knife 203e maintains close contact with the inner wall of the boiler to prevent slag from adhering to the side wall and not being cleaned.

[0054] In summary, this invention, by setting up a limit adjustment unit and a slag removal unit, rotates the dual drive assembly to push the extension assembly downward, causing the slag removal assembly to open and increase the contact range, facilitating the cleaning of boilers of different diameters. Pressing down on the positioning clamping assembly fixes the whole assembly, while simultaneously positioning the limit adjustment unit and ensuring the stability of the fixed state of the positioning clamping assembly. Sliding down on the dual drive assembly squeezes the limit assembly to release the locking limit on the moving assembly. Rotating the dual drive assembly again causes the moving assembly to rotate and move downward under the thread limit of the positioning clamping assembly, allowing the slag removal assembly at the bottom to rotate downward and scrape the slag adhering to the inner wall of the boiler. At the same time, the threaded locking state of the inner screw maintains the stability of the extension assembly after it is deployed.
