Description

Technical Field

[0001] This utility model belongs to the field of waste incineration technology and relates to an adjustable anti-slip material device for waste incinerators. Background Technology

[0002] With the rapid development of the national economy and the acceleration of urbanization, people's living standards are rising, and the amount of urban household waste is increasing. The drawbacks and contradictions of landfill disposal are becoming increasingly apparent. Incineration, which can reduce reliance on large amounts of land resources and meet the dual requirements of environmental protection and resource utilization, has gradually become the main method of waste disposal. In recent years, encouraged by national industrial policies promoting the reduction, harmlessness, and resource utilization of household waste, my country's waste incineration industry has entered a period of rapid development. Large and medium-sized cities have successively built new waste incineration plants, and the level of harmless treatment and resource utilization of waste is getting higher and higher.

[0003] The main process of waste incineration is as follows: waste is fed into the incinerator's feed hopper by a grab bucket, falls through a chute onto the feeding platform, and is then pushed by multiple horizontally arranged feeding trolleys onto the corresponding grates below the furnace. The waste is dried, burned, and completely combusted on the grates. The slag after combustion falls from the tail of the grate into a slag remover for cooling before being pushed out. The reciprocating movement of each feeding trolley on the feeding platform is hydraulically driven and controlled. The operating cycle of each feeding trolley is adjusted according to the combustion status of the waste on each grate area to ensure stable operation of the waste incineration process within the furnace, achieving on-demand feeding under stable combustion conditions. When a large amount of waste falls from the feed chute onto the feeding platform, due to the platform's wide width and large space, and influenced by inertia and material characteristics, some waste may slide off the platform onto the grate, resulting in uncontrolled waste feeding. This leads to a mismatch between the amount of waste arriving on the grate and the operational demand, adversely affecting the stable operation and control of waste combustion.

[0004] In light of this, researching how to control material slippage on the feeding platform and ensure on-demand feeding of the grate is a hot topic and practical need in the waste incineration industry. Currently, the industry has proposed some solutions, such as horizontally arranging multiple fin-shaped metal blocks at the front end of the feeding platform to increase operating resistance and reduce the possibility of material slippage. However, the design size of these metal blocks is difficult to select. If the size is too small, the anti-slip effect is not obvious; if the size is too large, it will obstruct the normal feeding of waste, potentially affecting the smoothness of feeding, and the characteristics of the waste entering the furnace may also fluctuate. Moreover, the metal blocks are difficult to adjust after installation. Therefore, in actual operation, this anti-slip solution is unlikely to achieve the desired effect.

[0005] Therefore, it is necessary to study new solutions for anti-slip materials for incinerator waste, which can achieve on-demand feeding according to the combustion conditions and can be flexibly adjusted according to the characteristics of the waste entering the furnace, so as to meet the requirements of continuous, stable and reliable feeding and operation of the incinerator. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an adjustable anti-slip material device for a waste incinerator, including multiple anti-slip material devices arranged laterally on the top surface above the feeding platform, which are used to alleviate the rapid movement of waste and prevent the waste falling from the feeding chute from sliding onto the grate below. This solves the problem of unreliable waste supply and unstable waste combustion caused by material slippage. By controlling the operating cycle of each feeding trolley, material is fed to the corresponding grate as needed, promoting stable combustion of waste on the grate.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable anti-slip material device for a waste incinerator includes multiple anti-slip material devices arranged laterally at intervals on the furnace shell above the front end of the feeding platform. Each anti-slip material device includes a lower support, an upper bracket, an anti-slip rod, and a locking shaft. The lower support consists of a lower flange and a protective sleeve fixedly connected to one side of the lower flange. The lower flange is fixedly connected to the furnace shell panel of the furnace shell, and the protective sleeve penetrates the furnace shell and communicates with the space above the front end of the feeding platform.

[0009] The upper support consists of an upper flange and a support sleeve fixedly connected to one side of the upper flange. The upper flange is connected to the side of the lower flange away from the protective sleeve via the side away from the support sleeve.

[0010] The anti-slip rod is inserted into the space above the front end of the feeding platform through the lower support and the upper bracket, and has a plurality of adjustment holes that are spaced apart along its length and penetrate its body radially. The inner diameter of the adjustment holes is larger than the outer diameter of the locking shaft that overlaps the top of the support sleeve, so that the vertical position of the anti-slip rod can be restricted by the locking shaft passing through different adjustment holes.

[0011] Furthermore, a groove adjacent to the inner hole is provided at the connection surface of the upper flange and the lower flange, and an asbestos rope is installed in the groove to secure the asbestos rope through the upper flange and the lower flange to clamp the anti-slip rod passing through the lower support and the upper bracket.

[0012] Furthermore, bolt holes are provided on both the upper flange and the lower flange for connecting the upper flange and the lower flange.

[0013] Furthermore, the length of the locking shaft is greater than the outer diameter of the support sleeve, and pin holes are provided at both ends of the locking shaft.

[0014] Furthermore, the number of anti-slip material devices is the same as the number of feeding trolleys arranged laterally on the feeding platform.

[0015] Furthermore, the anti-slip material device is arranged in the same lateral position as the feeding trolley, so that the interval between two adjacent anti-slip material devices is the same as the interval between two adjacent feeding trolleys.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention provides an adjustable anti-slip material device for waste incinerators, aiming to solve the problems of unreliable waste delivery and unstable combustion caused by material slippage on the feeding platform during waste incineration. This device effectively prevents waste from sliding onto the grate due to inertia and mutual entanglement, ensuring that the feeding trolley can deliver waste to the grate as needed, thereby maintaining stable combustion and efficient operation of the waste on the grate.

[0018] The core of this anti-slip material device lies in its adjustability. On one hand, the number of devices can be flexibly determined based on the width of the feeding platform and the number of feeding trolleys, ensuring that the lateral space of the feeding platform can fulfill the anti-slip material function, greatly improving the overall stability and reliability of the incinerator feeding. On the other hand, the effective length of the anti-slip rods inserted into the furnace can be reasonably adjusted according to the incinerator type and waste characteristics, meeting the anti-slip material operation requirements under different operating conditions, demonstrating extremely strong adjustability and adaptability.

[0019] Furthermore, this invention enhances the practicality and convenience of the device through a series of ingenious designs. For example, an asbestos rope is installed in the groove at the connection surface between the upper and lower flanges. The asbestos rope is pressed and clamped to the anti-slip rod by a tight connection, ensuring the stability of the device while facilitating adjustment and replacement. The locking shaft design allows for easy limitation of the vertical position of the anti-slip rod, further improving the reliability and ease of use of the device. In summary, the adjustable anti-slip material device for waste incinerators provided by this invention not only innovatively solves the problem of material slippage but also provides strong support for the stable operation and efficient development of the waste incineration industry through its adjustability and practicality.

[0029] Please see Figures 1-2 An adjustable anti-slip material device for a waste incinerator includes multiple anti-slip material devices 1 arranged laterally at intervals on a furnace shell 4 above the front end of a feeding platform. The furnace shell 4 includes a furnace shell panel 41 arranged on the outer surface and refractory castable arranged on the inner side. The furnace shell 4 at the location where the anti-slip material device 1 is installed is a horizontal plane parallel to the feeding platform 3.

[0030] The upper rear end of the feeding platform 3 is connected to the feeding chute, and the front of the feeding platform is connected to the furnace. Below the furnace is the grate. Waste falls onto the feeding platform 3 through the feeding chute and is then pushed onto the grate below by multiple reciprocating feeding trolleys 2 arranged horizontally on the feeding platform 3.

[0031] The key to this embodiment is that the anti-slip material device 1 includes a lower support 11, an upper bracket 12, an anti-slip rod 13, a locking shaft 14, and an asbestos rope 15. The lower support 11 consists of a lower flange 111 and a protective sleeve 112 fixedly connected to one side of the lower flange 111. The lower flange 111 is fixedly connected to the furnace shell panel 41, and the protective sleeve 112 penetrates the furnace shell 4 to connect the upper space at the front end of the feeding platform.

[0032] The upper support 12 consists of an upper flange 121 and a support sleeve 122 fixedly connected to one side of the upper flange 121. The upper flange 121 is detachably connected to the side of the lower flange 111 away from the protective sleeve 112 via the side away from the support sleeve 122.

[0033] The anti-slip rod 13 is inserted into the space above the front end of the feeding platform through the lower support 11 and the upper bracket 12, and has a plurality of adjustment holes 131 that are spaced apart along its axial direction and penetrate its body radially. The inner diameter of the adjustment hole is larger than the outer diameter of the locking shaft 14 that overlaps the top of the support sleeve 122, thereby limiting the vertical position of the anti-slip rod 13 by the locking shaft 14 passing through the adjustment hole.

[0034] The upper flange 121 has a groove adjacent to its inner hole at the connection surface for connecting the lower flange 111, so as to install the asbestos rope 15. The asbestos rope 15 is clamped by the upper flange 121 and the lower flange 111 to achieve the purpose of sealing the flue gas and clamping the anti-slip rod 13 passing through the lower support 11 and the upper bracket 12.

[0035] Specifically, the upper bracket 12 and lower support 11 of the anti-slip material device are both made of metal and are connected by upper and lower flanges and fastened with bolts. The anti-slip rod 13 passes through the middle of the upper bracket 12 and the lower support 11. The locking shaft, which overlaps the top of the upper bracket 12, passes through an adjustment hole 131 of the anti-slip rod to fix the anti-slip rod.

[0036] The lower support 11 consists of a lower flange 111 and a protective sleeve 112 welded below. Both the lower flange 111 and the protective sleeve 112 adopt a circular structure. The lower flange 111 has four bolt holes evenly distributed on its outer ring. The center hole of the lower flange coincides with the inner diameter of the protective sleeve and has the same size. The hole diameter is slightly larger than the outer diameter of the anti-slip rod 13. The height of the protective sleeve 112 is the same as the thickness of the furnace shell 4 (the thickness of the furnace shell panel plus the refractory casting material) on the top surface above the feeding platform. That is, during application and installation, the lower flange 111 of the lower support 11 overlaps and supports the furnace shell panel 41 (metal material) above the furnace shell above the feeding platform, and the four sides are sealed by welding. The protective sleeve 112 is wrapped in the refractory casting material, so that the refractory casting material and the anti-slip rod 13 are isolated from each other and the mutual influence is eliminated.

[0037] The upper support 12 consists of an upper flange 121 and a support sleeve 122 welded to the upper part. Both the upper flange and the support sleeve adopt a circular structure. The outer ring of the upper flange has four bolt holes evenly distributed. The center hole of the upper flange coincides with the center of the inner diameter of the support sleeve. The diameter of the center hole of the support sleeve is slightly larger than the outer diameter of the anti-slip rod. The diameter of the center hole of the upper flange is larger than the diameter of the center hole of the support sleeve. That is, the upper flange, the support sleeve and the lower flange form a groove for installing the asbestos rope 15 at the connection. During installation, the upper support overlaps the lower support and is fastened by bolts between the upper flange and the lower flange. At the same time, the asbestos rope 15 is filled and pressed into the groove.

[0038] The upper bracket 12 can be designed with a split structure that is divided into two equal halves, which facilitates the installation of the upper bracket and also makes it convenient to tighten the asbestos rope after the anti-slip rod is installed and adjusted, so as to achieve reliable sealing performance of the asbestos rope.

[0039] The anti-slip rod 13 adopts a solid round rod structure, is made of high-performance and high-strength metal material, has a sufficient length, and has multiple circular adjustment holes 131 that pass vertically through the shaft along the length, which serve as locking holes for sliding connection with the locking shaft; the locking shaft 14 adopts a small round rod structure with pin holes at both ends, and its outer diameter is slightly smaller than the diameter of the adjustment holes 131 on the anti-slip rod, and the length of the locking shaft is larger than the outer diameter of the support sleeve 122 of the upper bracket, so as to overlap it.

[0040] After the anti-slip rod 13 is inserted from top to bottom into the support sleeve of the upper bracket and the protective sleeve of the lower support to a certain position, the locking shaft can be passed through the adjustment hole 131 on the anti-slip rod near the upper end face of the support sleeve, and the two ends of the locking shaft are overlapped on the upper end of the support sleeve. The locking shaft and the anti-slip rod are fixed by passing pins through the pin holes at both ends of the locking shaft, thereby realizing the hoisting and fastening of the anti-slip rod on the support sleeve 122. The asbestos rope pressed in the groove also wraps and tightens the anti-slip rod, ensuring the isolation between the inside and outside of the anti-slip material device. This can effectively seal the area of ​​the anti-slip material device installed above the feeding platform, preventing hot flue gas in the furnace from leaking out of the furnace, causing waste of heat energy and environmental pollution.

[0041] The effective length of the anti-slip rod 13, extending beyond the lower support (i.e., beyond the length of the refractory casting material), is also the visible portion of the anti-slip rod above the feeding platform. This portion of the anti-slip rod obstructs the falling waste from the feed chute, preventing it from sliding onto the grate below, thus fulfilling its anti-slip function. The effective length can be adjusted according to the waste characteristics and operating conditions. Different insertion depths are selected, and then the anti-slip rod is pierced, hoisted, and secured at the corresponding positions using a locking shaft. The selected effective length must prevent the waste from sliding off without affecting the normal transport and supply of waste when the feeding trolley is pushed.

[0042] The lateral width of the feeding platform is determined by the incinerator's processing capacity, and the number of feeding trolleys varies depending on the incinerator model. Different numbers of anti-slip devices can be installed laterally based on the width of the feeding platform and the number of feeding trolleys to achieve overall anti-slip functionality for the feeding platform.

[0043] In this embodiment, it is preferable that the number of anti-slip material devices 1 is the same as the number of feeding trolleys 2, and that they are arranged in the same lateral position as the feeding trolleys 2, so that the interval between two adjacent anti-slip material devices 1 is the same as the interval between two adjacent feeding trolleys 2.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
