Description

Technical Field

[0001] The present invention relates to the field of garbage disposal, in particular to a garbage incinerator feeding device and a garbage incineration system. Background Art

[0002] The function of the feeding grate is to continuously push the garbage from the hopper chute to the incineration grate, so that the garbage can be burned continuously and stably on the incineration grate. Therefore, the role of the feeding grate is very important in the use of the garbage incinerator.

[0003] With the progress of urbanization and the improvement of people's living standards, the amount of domestic waste generated is increasing, and the treatment facilities are gradually developing in the direction of large capacity and scale. With the development of large-scale waste treatment facilities, the size of the feeding grate in the width direction continues to increase. The increase in the size in the width direction reduces the feeding uniformity of the feeding grate. The uneven feeding often causes the incinerator to burn unevenly, which brings great difficulties to the production operation adjustment. At the same time, the large-scale development of waste treatment facilities has caused a corresponding increase in the number of feeding trolleys in the width direction. Jams frequently occur during movement, which greatly reduces the feeding uniformity and stability, and thus greatly reduces the reliability of the feeding system, which directly affects the economy and reliability of the entire incinerator and even the entire waste incineration power plant.

[0004] In order to solve the problems in the prior art, the present invention provides a waste incinerator feeding device and a waste incineration system. Summary of the Invention

[0005] The Summary of the Invention introduces a series of simplified concepts that will be further described in the Detailed Description of the Invention. The Summary of the Invention is not intended to limit the key features and essential features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] In order to solve the problems in the prior art, the present invention provides a feeding device for a waste incinerator, comprising a feeding platform and at least two feeding trolleys arranged in parallel on the feeding platform, wherein:

[0007] A spacer is provided on the feeding platform, and the spacer is used to separate the feeding platform into at least two independent areas arranged in parallel, and each of the at least two independent areas is arranged in a one-to-one correspondence with each of the at least two feeding carts, so that one feeding cart is provided in each of the independent areas.

[0008] Exemplarily, the top of the spacer extends toward the feeding trolley on both sides to form a flange type of the spacer, wherein the portion of the top of the spacer extending toward both sides constitutes a flange, and the bottom of the flange is higher than the top of the feeding trolley and covers the gap between the spacer and the side wall of the feeding trolley.

[0009] Exemplarily, the spacer device includes a partition and a cover plate located on the partition, and portions of the cover plate located on both sides of the partition constitute the flanges.

[0010] Exemplarily, a guide device is also included to guide the garbage material to the feeding platform.

[0011] Exemplarily, it includes the guide device provided corresponding to each of the feeding trolleys.

[0012] Exemplarily, the guide device includes a suspension beam arranged above the feeding trolley and a guide plate suspended on the suspension beam.

[0013] Exemplarily, the guiding device further includes a supporting device disposed below the suspension beam for supporting the suspension beam.

[0014] Exemplarily, the supporting device and the spacing device are arranged in a one-to-one correspondence.

[0015] Exemplarily, the supporting device includes a supporting column, and the supporting column is fixedly connected to the spacer device as a whole, or the supporting column and the spacer device are integrally formed.

[0016] The present invention also provides a waste incineration system, comprising the waste incinerator feeding device as described in any one of the above items.

[0017] According to the waste incinerator feeding device and waste incineration system of the present invention, a spacing device is set on the feeding platform to separate the feeding platform into independent areas corresponding to each feeding trolley, so that the feeding trolleys can move independently in the independent areas without affecting each other. It ensures that the trolleys run smoothly and will not deviate or derail. Compared with the traditional adjacent arrangement of feeding trolleys without a spacing device, it effectively reduces the probability of the feeding trolley derailing or solves the problem of the adjacent feeding trolley being stuck due to interference caused by the derailment of the feeding trolley. At the same time, the gap between adjacent feeding trolleys is occupied by the spacing device, which reduces the possibility of foreign matter entering between adjacent feeding trolleys, thereby reducing the probability of the feeding trolley being stuck by foreign matter, and greatly improving the reliability and stability of the waste incinerator feeding device. The waste incinerator feeding device of the present invention can improve the feeding uniformity of the waste incinerator feeding device while avoiding the jamming of the feeding trolley.

[0018] The waste incinerator feeding device according to the present invention can meet the needs of large-scale waste incineration systems with high waste feed volumes. Compared with multiple small-scale similar devices connected in parallel, it occupies a smaller footprint, is less expensive, and has lower installation, commissioning, operation, and maintenance costs. The waste incineration system according to the present invention successfully solves the inherent problems of uneven feeding and easy jamming of large-capacity feeding devices, thereby improving combustion stability and efficiency.

However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete and to fully convey the concepts of these exemplary embodiments to those skilled in the art.

[0031] Example 1

[0032] In order to solve the problems in the prior art, the present invention provides a feeding device for a waste incinerator, comprising:

[0033] A feeding platform and at least two feeding trolleys arranged in parallel, wherein a spacing device is provided on the feeding platform, the spacing device is used to separate the feeding platform into at least two independent areas arranged in parallel, and each of the at least two independent areas is arranged in a one-to-one correspondence with each of the at least two feeding trolleys, so that one feeding trolley is provided in each of the independent areas.

[0034] See below Figures 1-6 A feeding device for a waste incinerator according to the present invention is exemplarily described. Figure 1 This is a structural schematic diagram of a feeding device for a waste incinerator according to one embodiment of the present invention; Figure 2 This is a schematic structural diagram of a spacing device in a feeding device of a waste incinerator according to one embodiment of the present invention; Figure 3This is a schematic structural diagram of a guide device in a feeding device of a waste incinerator according to one embodiment of the present invention; Figure 4 This is a schematic structural diagram of a guide device in a feeding device of a waste incinerator according to one embodiment of the present invention; Figure 5 Based on Figure 1 Schematic diagram of the structure of the feeding device of the garbage incinerator observed in the direction of arrow A; Figure 6 Based on Figure 1 Schematic diagram of the structure of the feeding device of the waste incinerator observed in the direction of arrow B.

[0035] See Figure 1 According to one embodiment of the present invention, a waste incinerator feeding device comprises a feeding platform 1 and at least two feeding trolleys 2, the feeding trolleys 2 are arranged in parallel (at Figure 1 (In the middle, they are arranged side by side in a direction perpendicular to the paper surface).

[0036] The feeding trolley 2 is used to push the garbage materials on the feeding platform 1 to the garbage incinerator for incineration.

[0037] With the development of large-scale garbage treatment facilities, the grate size in the width direction is constantly increasing, so that the width span of the garbage incinerator feeding device is increased. Figure 1 The span in the direction perpendicular to the paper increases, and the number of feeding trolleys increases. In one example, the feeding device of a garbage incinerator includes 6 feeding trolleys, which together push the garbage on the feeding platform onto the grate of the garbage incinerator.

[0038] As the number of feeding trolleys increases, they are prone to deviation or derailment during movement, interfering with the movement of adjacent feeding trolleys. At the same time, the gaps between adjacent feeding trolleys are prone to foreign matter entering, causing the movement of the feeding trolley to become stuck, greatly reducing the reliability of the feeding device of the waste incinerator. In order to solve the above problems, the present invention, such as Figure 1 As shown, a spacing device 3 is provided on the feeding platform 1 to separate the feeding platform 1 into independent areas corresponding to each feeding trolley 2. The feeding trolleys move independently in the independent areas without affecting each other.

[0039] Since the feeding trolleys 2 are in their own independent areas, there are fixed spacers on both sides of the feeding trolleys 2, which ensures that the trolleys run smoothly and will not deviate or derail. Compared with the traditional adjacent arrangement of feeding trolleys without spacers, the problem of derailment of the feeding trolleys is effectively avoided, and the probability of mutual interference due to jamming or derailment of adjacent feeding trolleys is reduced. At the same time, the gaps between adjacent feeding trolleys are occupied by spacers to prevent foreign objects from entering between adjacent feeding trolleys, solving the problem of the feeding trolleys being stuck by foreign objects, and greatly improving the reliability and stability of the feeding device of the waste incinerator.

[0040] The waste incinerator feeding device according to the present invention reduces the probability of mutual interference caused by jamming or derailment of adjacent feeding trolleys, thereby improving the uniformity of feeding.

[0041] Furthermore, the waste incinerator feeding device according to the present invention can meet the needs of large-scale waste incineration systems with large waste feed volumes. Compared with multiple small-scale similar devices connected in parallel, it occupies a smaller footprint, is less expensive, and has lower installation, commissioning, operation, and maintenance costs. Furthermore, it successfully solves the inherent problems of uneven feeding and easy jamming of large-capacity feeding devices.

[0042] In one embodiment of the present invention, the top of the spacer extends toward the feeding trolley on both sides so that the spacer forms a flange type, wherein the portion of the top of the spacer extending toward both sides constitutes a flange, and the bottom of the flange is higher than the top of the feeding trolley and covers the gap between the spacer and the side wall of the feeding trolley.

[0043] The spacer is set to a flange type so that the flange part is higher than the feeding trolley and covers the gap between the spacer and the side wall of the feeding trolley, so as to prevent the garbage material from falling into the gap between the feeding trolley and the side wall of the spacer during the unloading process, causing the feeding trolley to be stuck.

[0044] Exemplarily, the spacer comprises a partition and a cover plate located on the partition, and the portion of the cover plate extending beyond both sides of the partition forms the flange. Figure 2 , shows a schematic structural diagram of a spacing device in a feeding device of a waste incinerator according to an embodiment of the present invention.

[0045] like Figure 2 As shown, the spacer 3 includes a partition 31 and a cover plate 32 located on the partition 31, and a feeding trolley 2 is provided on both sides of the spacer 3. The portion of the cover plate 32 that extends beyond the two sides of the partition 31 forms a flange, which covers the gap between the partition 31 and the feeding trolley 2.

[0046] It should be understood that in this embodiment, the spacer is arranged in the form of a partition and a cover plate located on the partition for exemplary purposes only. Those skilled in the art should understand that the spacer can also be formed in any other form to form the above-mentioned flange type, such as integrally formed to form the above-mentioned flange type, which are all applicable to the present invention.

[0047] Exemplarily, there is sufficient clearance between the spacer and the feeding trolley to allow the trolley to run smoothly without derailing. At the same time, the clearance cannot be too large to allow foreign matter to easily enter. Exemplarily, the clearance between the spacer and the feeding trolley is in the range of 2mm-5mm. In one embodiment of the present invention, the clearance between the spacer and the feeding trolley is 3mm.

[0048] Furthermore, illustratively, a gap is provided between the flange and the top of the feed trolley to allow the trolley to move freely beneath the flange while also preventing foreign objects from entering the gap and jamming the trolley. Exemplarily, the gap between the flange of the spacer and the top of the feed trolley ranges from 2 mm to 5 mm. In one embodiment according to the present invention, the gap between the flange of the spacer and the top of the feed trolley is 3 mm.

[0049] Continue to see below Figure 1 、 Figure 3 and Figure 4 The feeding device for a waste incinerator according to the present invention is exemplarily introduced.

[0050] Exemplarily, the waste incinerator feeding device also includes a driving device.

[0051] like Figure 1 As shown in the figure, in the feeding device of the garbage incinerator, the feeding trolley 2 is driven by the driving device 4, thereby pushing the garbage on the feeding platform 1 into the incinerator. A guide wheel 5 and a support wheel 6 are provided under the feeding trolley 2. The driving device 4 drives the feeding trolley 2 to move forward and backward (in the Figure 1 (In the figure, the feeding trolley 2 moves forward to the right and moves backward to the left). The feeding trolley 2 and its drive device 4, guide wheels 5, support wheels 6, and feeding platform 1 are all supported by a supporting steel frame 7, so that the waste incinerator feeding device is located at a position higher than the waste incinerator.

[0052] Exemplarily, the driving device 4 is configured to drive a hydraulic cylinder.

[0053] Exemplarily, the feeding device of the garbage incinerator also includes a control device, which controls the driving device 4 to drive the movement speed of the feeding trolley 2, so that the movement speed of each feeding trolley 2 is consistent or different or the same in groups (for example, in the case of 6 feeding trolleys, the movement speeds of the 6 feeding trolleys are controlled to be the same in pairs), and the uniform distribution of garbage on the incineration grate is achieved through the individual or combined control of the feeding trolleys.

[0054] For example, by controlling the movement combination of the feeding trolleys, the overall front end surfaces of all the feeding trolleys are set to be an arc surface (concave or convex) or a vertical plane.

[0055] Exemplarily, by controlling the movement combination of the feeding trolleys, the overall front end surfaces of all the feeding trolleys are set to be stepped.

[0056] The speed and front end of the feeding trolley can be set differently according to the thickness of the feeding layer of the incinerator grate, which improves the flexibility of the feeding trolley and solves the problem of uneven feeding.

[0057] It should be understood that, in this embodiment, the control device is provided to control the driving device to control the speed of the feeding trolley, and the above-mentioned example of the front end face of the feeding trolley and the control device is shown to achieve uniform feeding is merely exemplary. Those skilled in the art should understand that any other implementation method can be used to achieve uniform feeding of the feeding trolley and is applicable to the present invention.

[0058] Continue to read Figure 1 The waste incinerator feeding device further includes a guide device 8. The guide device 8 is used to guide the waste material so that the waste material passes through the guide plate device 8 to the feeding platform 1, and the feeding trolley 2 moves forward to push the waste material on the feeding platform 1 to the waste incinerator.

[0059] Exemplarily, the guide device 8 includes a guide plate. In this embodiment, the guide plate is used for guidance, which greatly reduces the weight of the waste incinerator feeding device and reduces the load on the supporting steel frame 7 and the guide plate suspension beam 82.

[0060] Furthermore, illustratively, the guide device 8 also includes a suspension beam arranged above the feeding trolley and spanning the feeding trolley, and the guide plate is installed by being suspended on the suspension beam.

[0061] See Figure 3 and Figure 4 FIG. 1 shows a schematic structural diagram of a guide device in a feeding device of a waste incinerator according to an embodiment of the present invention. Figure 3 、 Figure 4 As shown, the guide device 8 includes a guide plate 81 and a suspension beam 82 arranged above the feeding trolley and spanning the feeding trolley. The guide plate 81 is connected to the suspension beam 82 by bolts.

[0062] As the processing scale increases, the width of the feeding grate increases, and the deformation and stress borne by the suspension beam in the corresponding feeding device also increase accordingly. In the present invention, in order to further ensure safety, a support device is provided under the suspension beam. Figure 4 As shown, a support device 83 is provided under the suspension beam 82. Support device 83 supports the suspension beam 82 and prevents excessive deformation and stress. Furthermore, the presence of support device 83 prevents excessive downward deformation of the suspension beam 82, which could result in a narrow gap between the guide plate 81 and the upper surface of the feeding trolley 2 and cause the feeding trolley to become stuck.

[0063] In one embodiment of the present invention, the supporting means and the spacing means are provided in a one-to-one correspondence. Figure 1 、 Figure 5 and Figure 6 , the structures of the supporting device and the spacing device in the feeding device of the garbage incinerator according to one embodiment of the present invention are exemplarily introduced, wherein Figure 5 Shown as based on Figure 1 Schematic diagram of the structure of the feeding device of the garbage incinerator observed in the direction of arrow A. Figure 6 Based on Figure 1 Schematic diagram of the structure of the feeding device of the garbage incinerator observed in the direction of arrow B. Figure 1 、 Figure 5 and Figure 6 As shown, in the feeding device of the waste incinerator according to the present invention, a spacing device 3 is provided on the feeding platform 1 to divide the feeding platform 1 into 6 independent areas, wherein a feeding trolley 2 is provided in each independent area, and a supporting device 83 is provided at one end of the spacing device 3 close to the driving end of the feeding trolley, and the supporting device 83 is used to support the suspension beam across the feeding trolley 2.

[0064] Exemplarily, the support device includes a support column, which is fixedly connected to the spacer as a whole, or the support column and the spacer are integrally formed. Connecting the support column and the spacer as a whole or integrally forming the support column and the spacer further distributes stress on the suspension beam and the guide plate to the support column and the spacer, thereby improving the stability of the support structure and thereby enhancing the safety of the waste incinerator feeding device.

[0065] The above is an exemplary introduction to the feeding device of a waste incinerator according to the present invention. According to the present invention, a spacing device is provided on the feeding platform to separate the feeding platform into independent areas corresponding to each feeding trolley. The feeding trolleys move independently in independent areas without affecting each other. Since the feeding trolleys are in their own independent areas, the two sides of the feeding trolleys are fixed spacing devices, which ensures that the trolleys run smoothly without deviation or derailment. Compared with the traditional adjacent arrangement of feeding trolleys without spacing devices, the probability of the feeding trolley derailing is effectively reduced or the problem of jamming caused by interference with adjacent feeding trolleys due to derailment of the feeding trolley is solved. At the same time, the gaps between adjacent feeding trolleys are occupied by spacing devices, which reduces the possibility of foreign matter entering between adjacent feeding trolleys, thereby reducing the probability of the feeding trolley being jammed by foreign matter, and greatly improving the reliability and stability of the feeding device of the waste incinerator. The use of the feeding device of the waste incinerator of the present invention can improve the feeding uniformity of the feeding device of the waste incinerator while avoiding the jamming of the feeding trolley.

[0066] The waste incinerator feeding device according to the present invention can meet the needs of large-scale waste incineration systems with high waste feed volumes. Compared with multiple small-scale similar devices connected in parallel, it occupies a smaller footprint, is less expensive, and has lower installation, commissioning, operation, and maintenance costs. Furthermore, it successfully solves the inherent problems of uneven feeding and easy jamming of large-capacity feeding devices, ensuring continuous, uniform, and stable feeding of large-capacity waste incineration systems.

[0067] Example 2

[0068] The present invention also provides a waste incineration system, which includes the waste incinerator feeding device and the waste incinerator as described in the first embodiment.

[0069] Among them, the garbage incinerator feeding device pushes the garbage materials into the incineration grate of the garbage incinerator.

[0070] Since a spacing device is provided on the feeding platform, the feeding platform is separated into independent areas corresponding to each feeding trolley. The feeding trolleys move independently in the independent areas without affecting each other, which ensures that the trolleys run smoothly and do not deviate or derail. Compared with the traditional adjacent arrangement of feeding trolleys without a spacing device, the probability of the feeding trolley derailing is effectively reduced or the problem of the adjacent feeding trolley being stuck due to interference caused by the derailment of the feeding trolley is solved. At the same time, the gaps between adjacent feeding trolleys are occupied by the spacing device, which reduces the possibility of foreign matter entering between adjacent feeding trolleys, thereby reducing the probability of the feeding trolley being stuck by foreign matter, greatly improving the reliability and stability of the feeding device of the garbage incinerator, thereby improving the stability of the combustion working condition of the garbage incineration system. Due to the garbage incinerator feeding device, while avoiding the jamming of the feeding trolley, the feeding uniformity of the garbage incinerator feeding device is improved, and the fuel efficiency of the garbage incineration system of the present invention is also improved.

[0071] For example, the waste incineration system of the present invention utilizes a large-scale, large-scale incinerator. Compared to parallel operation of multiple smaller-scale units of the same type, this system occupies a smaller footprint, is more economical, and offers lower installation, commissioning, operation, and maintenance costs. Because the waste incinerator feeding device of the present invention successfully addresses the inherent challenges of uneven feeding and easy jamming of large-scale feeding devices, the waste incineration system of the present invention ensures continuous, uniform, and stable feeding of large-scale waste incineration systems.

[0072] The present invention has been described through the above-described embodiments. However, it should be understood that the above-described embodiments are for illustrative and illustrative purposes only and are not intended to limit the present invention to the described embodiments. Furthermore, it will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments and that various variations and modifications may be made based on the teachings of the present invention, all of which fall within the scope of the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
