Description

Technical Field

[0001] The present invention relates to the field of boiler slag drying machines, in particular to a material receiving mechanism and a boiler slag drying machine system. Background Art

[0002] When the dry slag machine system is in operation, after the slag enters the slag pit, small slag blocks pass through the grille and fall directly onto the steel belt conveyor, while large slag blocks fall onto the grille for pre-cooling, and are then crushed by the horizontally moving toothed extrusion head and fall onto the steel belt conveyor.

[0003] Although the grille can prevent large slag blocks from falling directly onto the steel belt conveyor, in order to reduce the possibility of blockage, the grille can generally only block slag blocks larger than 200mm. Slag blocks that are about the size of a football may still pass through the grille and fall directly onto the steel belt conveyor, thereby causing a greater impact on the steel belt conveyor and affecting its life. In addition, the amount of boiler slag discharged varies greatly at different time periods. In a certain period, more slag may be discharged. Slag blocks accumulated at the same position on the steel belt conveyor can easily cause blockage, especially when they slide down and form accumulations during transportation in the transition section, affecting normal transportation. Summary of the Invention

[0006] In a preferred embodiment of the material receiving mechanism of the present invention: the adjusting portion further includes a reset member, which is connected to the material blocking member.

[0011] In a preferred embodiment of the material receiving mechanism described in the present invention: the material blocking member includes a sealing plate arranged parallel to the material receiving plate, the sealing plate is located at the material dropout port, the upper end of the sealing plate is provided with a material blocking plate, the material blocking plate and the material receiving plate are arranged vertically, the side of the material blocking plate away from the sealing plate is the material blocking surface, the reset member includes a connecting plate fixedly connected to the sealing plate, a telescopic rod is fixed on the connecting plate, one end of the telescopic rod away from the connecting plate is fixed to the inner wall of the protective frame, and the outer sleeve of the telescopic rod is provided with a spring.

[0023] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0024] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0025] Reference Figures 1 to 3 , this embodiment provides a material receiving mechanism, including,

[0026] The receiving portion 1 has a receiving surface 12 that is inclined, and a material drop opening 13 on the receiving surface 12. The receiving surface 12 is located directly below the material falling direction. The falling material first falls on the receiving surface 12 of the receiving portion 1. Since the receiving surface 12 is an inclined surface, the material slides downward along the inclined surface to the material drop opening 13, and then falls from the material drop opening 13 to the conveying equipment;

[0027] The adjusting portion 2 is provided at the blanking opening 13 and connected to the material receiving surface 12. The adjusting portion 2 is provided at the blanking opening 13 and is used to adjust the size of the blanking opening 13;

[0028] The scraper part 3 is arranged at the side of the material drop opening 13 and is connected to the adjustment part 2. With the conveying direction of the conveying equipment as the front, the scraper part 3 is specifically arranged in front of the material drop opening 13 and is used to scrape the material falling from the material drop opening 13 onto the conveying equipment;

[0029] Among them, the adjusting part 2 includes a material stopper 21, which can be subjected to force to move relative to the material receiving surface 12, so as to change the relative position of the material stopper 21 and the blanking port 13, and the movement of the material stopper 21 can drive the scraper part 3 to move, so as to change the relative position of the scraper part 3 and the conveyed material. Specifically, the material stopper 21 is located at the blanking port 13, and blocks part of the blanking port 13. When the material is small, the material slides down along the material receiving surface 12 to the blanking port 13 and falls from the exposed part of the blanking port 13. When the material is large, it is difficult to discharge the material in time from the exposed part of the blanking port 13, and the material accumulates at the material stopper 21. Due to the action of gravity, the material squeezes the material stopper 21, causing the material stopper 21 to move, so that the exposed part of the blanking port 13 becomes larger, thereby increasing the discharge amount at the blanking port 13, so that the accumulated material can fall and be discharged in time.

[0030] In addition, the scraper part 3 is specifically located directly above the conveying equipment, and the distance between it and the conveying equipment is the thickness of the material when the conveying equipment is conveying. The scraping effect of the scraper part 3 can further improve the uniformity of the distribution of the material on the conveying equipment during transportation, and because the movement of the material blocking member 21 can drive the movement of the scraper part 3, when there is a lot of material, the movement of the material blocking member 21 makes the exposed part of the drop port 13 larger, thereby increasing the drop rate at the drop port 13. At the same time, the material blocking member 21 drives the scraper part 3 to rise away from the material on the conveying equipment, thereby increasing the material conveying thickness on the conveying equipment, that is, increasing the material conveying speed, to match the situation where the amount of material falling at the drop port 13 increases, and prevents a large amount of material from falling and then accumulating at the scraper part 3.

[0031] By setting the receiving part 1, the material falling from the boiler falls on the receiving surface 12 of the receiving part 1 and then falls on the conveying equipment from the drop opening 13, rather than falling directly on the conveying equipment, thereby reducing the impact on the conveying equipment and thus reducing impact damage;

[0032] At the same time, the materials are concentrated and fall down to the drop opening 13 and then fall onto the conveying equipment. Compared with the large opening at the bottom of the slag pit 6 and the materials fall to various places on the conveying equipment in a dispersed manner, the materials are more evenly distributed on the conveying equipment, which helps to improve the conveying stability.

[0033] In addition, the setting of the scraper part 3 can scrape the material on the conveying equipment relatively flat, improve the uniformity of the distribution of the material on the conveying equipment during transportation, and thus improve the transportation stability. Moreover, since the scraper part 3 can move with the blocking member 21, the scraping thickness of the scraper part 3 can change with the falling speed of the material at the drop port 13 to match different material falling amounts and prevent the material from accumulating at the scraper part 3.

[0034] In one embodiment provided in this application, referring to Figure 2 and Figure 3 The adjusting portion 2 further includes a reset member 22, which is connected to the stop member 21. When the stop member 21 is moved by force, the reset member 22 can be driven to deform, and the reset member 22 has a tendency to recover.

[0035] The reset member 22 is used to drive the material blocking member 21 to reset. Specifically, when there is a lot of material, the material squeezes the material blocking member 21 to move downward along the material receiving surface 12, and the exposed part of the drop port 13 becomes larger, thereby increasing the falling speed of the material. After the material becomes less, the extrusion effect of the material on the material blocking member 21 decreases, and the force of the reset member 22 to restore the deformation is greater than the extrusion force of the material, pushing the material blocking member 21 to move upward along the material receiving surface 12 to reset, so as to reduce the size of the exposed part of the drop port 13, and prevent the drop port 13 from opening too large and causing more material to fall from the drop port 13 instantly. Instead, when there is a lot of material, the drop port 13 drop speed gradually increases, and avoids the drop port 13 opening too large, causing more material to fall instantly and form accumulation on the conveying equipment.

[0036] In some embodiments, reference Figure 3 The material blocking member 21 has a material blocking surface 23 , and the material blocking surface 23 is perpendicular to the material connecting surface 12 .

[0037] The material blocking member 21 has a material blocking surface 23, which is arranged perpendicular to the material receiving surface 12, so that there is a certain accommodating space between the material blocking surface 23 and the material receiving surface 12. When there is a lot of material, the material can accumulate in the accommodating space and squeeze the material blocking surface 23, causing the material blocking member 21 to move and the exposed part of the blanking port 13 to gradually become larger.

[0038] In one embodiment provided in this application, referring to Figure 1 and Figure 2 The material receiving mechanism also includes a blocking portion 4, in which the receiving portion 1, the adjusting portion 2 and the scraping portion 3 are all arranged; the blocking portion 4 includes a protective frame 41 with an opening at the upper end, and a bottom plate 42 is provided at the lower end of the protective frame 41, and the blanking port 13 passes through the bottom plate 42.

[0039] On the one hand, the enclosure part 4 acts as a fence to prevent materials from falling from the side of the material receiving surface 12. On the other hand, the enclosure part 4 acts as an installation support for installing and supporting the receiving part 1, the adjusting part 2 and the scraping part 3. The enclosure part 4 specifically includes a protective frame 41 with an opening at the upper end. The upper end opening of the protective frame 41 is used for allowing materials to fall onto the material receiving surface 12. A bottom plate 42 is provided at the lower end of the protective frame 41 for installing and supporting related components. The drop port 13 passes through the bottom plate 42 so that the material can fall smoothly from the drop port 13 to the conveying equipment.

[0040] In some embodiments, reference Figure 2 The receiving portion 1 includes an inclined receiving plate 11, the side of which is fixed to the inner wall of the protective frame 41, the upper surface of the receiving plate 11 is the receiving surface 12, and the blanking port 13 is arranged near the lower end of the receiving plate 11.

[0041] The receiving part 1 specifically includes a material receiving plate 11, and the falling material falls directly on the material receiving plate 11. The material receiving plate 11 is specifically fixed on the inner wall of the protective frame 41. Of course, in order to reduce the impact of the material on the material receiving plate 11 and the installation position of the material receiving plate 11, an elastic buffer component can be installed between the material receiving plate 11 and the protective frame 41.

[0042] In some embodiments, reference Figure 3The material blocking member 21 includes a blocking plate 211 arranged parallel to the material receiving plate 11, the blocking plate 211 is located at the material drop port 13, and a blocking plate 212 is provided at the upper end of the blocking plate 211. The blocking plate 212 and the material receiving plate 11 are arranged vertically, and the side of the blocking plate 212 away from the blocking plate 211 is a blocking surface 23. The reset member 22 includes a connecting plate 221 fixedly connected to the blocking plate 211, and a telescopic rod 222 is fixed on the connecting plate 221. One end of the telescopic rod 222 away from the connecting plate 221 is fixed to the inner wall of the protective frame 41, and a spring 223 is provided on the outer sleeve of the telescopic rod 222.

[0043] The blocking plate 211 is arranged in parallel with the material receiving plate 11 and is abutted against the blanking opening 13 on the upper surface of the material receiving plate 11. The baffle plate 212 is integrally arranged at the upper end of the blocking plate 211 to withstand the pressure of the material; the reset member 22 is connected to the end of the blocking plate 211 away from the baffle plate 212. Specifically, during reset, when the exposed part of the blanking opening 13 becomes larger due to the extrusion of the baffle member 21, the material accumulated at the baffle plate 212 gradually falls down and the extrusion effect on the baffle plate 212 is reduced. When the elastic force of the spring 223 is greater than the extrusion force of the baffle plate 212 on the spring 223, the spring 223 stretches, pushing the baffle member 21 to move upward and reset, so that the exposed part of the blanking opening 13 becomes smaller.

[0044] In some embodiments, reference Figure 4 The scraper portion 3 includes a base 31 provided on the bottom plate 42, a scraper plate 32 is vertically movably provided in the base 31, and the base 31 is provided with limiting grooves 33 on both sides of the scraper plate 32, and limiting rods 36 are provided on both sides of the scraper plate 32, and the limiting rods 36 are located in the limiting grooves 33;

[0045] The scraper plate 32 is vertically arranged directly above the conveying equipment, and there is a certain distance between the scraper plate 32 and the conveying equipment. During transportation, the upwardly protruding materials are scraped relatively flat by the scraper plate 32, thereby improving the uniformity of material distribution on the conveying equipment. The scraper plate 32 is movable in the vertical direction to adjust the distance between the scraper plate 32 and the conveying equipment, thereby adjusting the scraping thickness. The setting of the limit groove 33 and the limit rod 36 limits the minimum height of the scraper plate 32 to prevent the scraper plate 32 from falling directly on the conveying equipment.

[0046] A sliding plate 34 is slidingly provided on the inner wall of the protective frame 41 , one end of the sliding plate 34 is fixedly connected to the material blocking member 21 , and the other end of the sliding plate 34 is fixedly connected to a deformation plate 35 , which passes through the base 31 and is connected to the upper end of the scraper plate 32 .

[0047] The specific adjustment method of the distance between the scraper plate 32 and the conveying equipment is that the inner wall of the protective frame 41 is specifically provided with a slide groove, the slide groove has the same inclination angle as the material receiving plate 11, and a sliding plate 34 is slidingly set in the slide groove, one end of the sliding plate 34 is connected to the material blocking member 21. Of course, the protective frame 41 is provided with a slide groove and a sliding plate 34 on both sides of the material blocking member 21, and the other end of the sliding plate 34 is hinged with a mounting plate, and a deformation plate 35 is fixed on the mounting plate. The deformation plate 35 is connected to the scraper plate 32. When the material blocking member 21 is squeezed and moved, it drives the sliding plate 34 to slide in the slide groove, and the cooperation between the sliding plate 34 and the slide groove is It plays a guiding role in the movement of the material blocking member 21. The sliding plate 34 slides and pulls the deforming plate 35 to move toward the outside of the base 31, and then pulls the scraper plate 32 upward, so that the distance between the scraper plate 32 and the conveying equipment becomes larger, and then the scraping thickness becomes larger to match the demand for rapid transportation of large amounts of material, avoid accumulation at the scraper plate 32, and when the material becomes less and the material blocking member 21 is reset, it drives the sliding plate 34 to move, and the scraper plate 32 is reset by the push of the sliding plate 34 and the gravity of the scraper plate 32; the scraper plate 32 is specifically made of lightweight steel plate, and the deforming plate 35 is a metal plate with a certain deformation ability, such as a thin steel plate.

[0048] In one embodiment provided in this application, referring to Figure 2 The material receiving mechanism also includes a forced discharging portion 5 , which includes a hydraulic cylinder 51 arranged on the inner wall of the protective frame 41 , and the telescopic end of the hydraulic cylinder 51 is facing the baffle plate 212 .

[0049] In order to prevent the material from accumulating at the blanking port 13 due to the failure of the material blocking member 21 to move, a forced discharge portion 5 is provided on one side of the material blocking member 21. When the material blocking member 21 fails to move, the hydraulic cylinder 51 is actuated to force the material blocking member 21 to move to expand the exposed portion of the blanking port 13, thereby quickly discharging the material.

[0050] Reference Figure 5 and Figure 6 This embodiment provides a boiler slag dryer system, including a material receiving mechanism, and further comprising:

[0051] Slag well 6, provided at the bottom of the boiler;

[0052] A steel belt conveyor 7 is provided at the lower part of the slag pit 6;

[0053] The material receiving mechanism is arranged between the slag pit 6 and the steel belt conveyor 7, the material receiving surface 12 is located at the lower part of the slag pit 6 in the discharge direction, and the material discharge port 13 is located at the upper part of the steel belt conveyor.

[0054] During specific installation, the upper end of the protection frame 41 is fixed to the lower end of the slag pit 6 , and the lower end of the protection frame 41 is fixed to the frames on both sides of the steel belt conveyor 7 .

[0055] The slag blocks falling from the slag pit 6 first fall on the receiving plate 11, and then slide to the drop port 13 and fall from the drop port 13 onto the steel belt conveyor 7, rather than falling directly on the steel belt conveyor 7, which reduces the impact on the conveying equipment and thus reduces impact damage; the drop port 13 is adjustable in size to prevent the drop port 13 from opening too large and causing more slag blocks to fall from the drop port 13 instantly, and to avoid the problem of more slag blocks falling instantly on the conveying equipment due to the larger drop port 13 opening, and when there are more slag blocks, the drop port 13 is too large to be dropped. The exposed portion 13 can gradually become larger by itself to discharge the material stably and quickly, and prevent the slag blocks from accumulating at the drop port 13; in addition, the setting of the scraper portion 3 can scrape the slag blocks on the steel belt conveyor 7 relatively flat, improve the uniformity of the distribution of the slag blocks on the conveying equipment during transportation, and thus improve the transportation stability, and because the scraper portion 3 can move with the blocking member 21, the scraping thickness of the scraper portion 3 can change with the falling speed of the material at the drop port 13, so as to match different material falling amounts and prevent the material from accumulating at the scraper portion 3.

[0056] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
