Description

Technical Field

[0001] This utility model relates to the field of municipal solid waste power generation technology, and in particular to a novel feeding hopper sealing structure for municipal solid waste power generation. Background Technology

[0002] In the process of municipal solid waste power generation, the feed hopper, as a crucial channel for waste to enter the power generation equipment, has a very important sealing performance. A good sealing structure can effectively prevent the emission of odors and dust, avoiding pollution to the surrounding environment. At the same time, it can also prevent outside air from entering, maintaining a stable working environment inside the power generation equipment, improving power generation efficiency and the safety of equipment operation.

[0003] However, existing sealing structures for waste-to-energy feed hoppers have many shortcomings. Some sealing structures have poor sealing performance, failing to meet environmental protection and equipment operation requirements; some sealing structures are prone to jamming and wear during waste feeding, affecting the smoothness of feeding and the service life of the sealing structure; and some sealing structures are complex, making repair and maintenance difficult and increasing operating costs.

[0004] Therefore, this application provides a novel feed hopper sealing structure for municipal solid waste power generation to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide a novel feeding hopper sealing structure for municipal solid waste power generation, in order to solve the problems of poor sealing effect, poor feeding, and difficult maintenance of existing feeding hopper sealing structures, thereby improving the sealing performance, operational stability and service life of the feeding hopper and reducing operating costs.

[0006] To achieve the above objectives, this application provides the following technical solution: a novel feeding hopper sealing structure for municipal solid waste power generation, comprising a feeding hopper, an upper sealing plate, and a lower sealing plate.

[0007] The feed hopper has symmetrical side plates on its left and right sides. The side plates are vertically arranged, and each set of side plates has symmetrical upper reset grooves on its front and rear parts. The upper reset grooves also include horizontal and vertical sections. The horizontal sections slope downwards towards the middle of the side plate. The front and rear sides of the side plates are connected to the back plate through a front plate, and the inclination of the back plate is greater than that of the front plate. This unique feed hopper structure design not only provides space for the installation and movement of the sealing plate, but also the different inclinations of the back plate and the front plate facilitate the smooth sliding of waste in the feed hopper.

[0008] The upper sealing plate has two sets symmetrically arranged on the front and rear sides of the top opening of the feed hopper. Traction columns and guide columns are symmetrically arranged on both the left and right sides of the upper sealing plate. The traction columns and guide columns on the same side are slidably connected in the same upper reset groove. The traction columns are located outside the guide columns, and an upper reset spring connects the traction columns to the side plate. The upper reset spring is used to reset the sealing state of the upper sealing plate. When waste enters the feed hopper, the upper sealing plate is subjected to the pressure of the waste, and the traction columns slide downwards along the horizontal section of the upper reset groove, opening the upper sealing plate and allowing the waste to enter smoothly. After the waste enters, the upper reset spring provides a reset force, and the traction columns slide upwards along the upper reset groove, causing the upper sealing plate to close again, thus sealing the top of the feed hopper.

[0009] A lower sealing plate is hinged to the lower part of the feed hopper. The hinge point of the lower sealing plate is close to the back plate. A swing arm is provided at one end of the lower sealing plate near the back plate. A through groove is provided on the back plate. The swing arm extends from the through groove and slides within the groove. The end of the swing arm is connected to the back plate via a lower return spring. After the waste enters the feed hopper, the lower sealing plate rotates and opens around the hinge point under the action of the waste's gravity, allowing the waste to fall into the equipment below. After the waste passes through, the lower return spring pulls the swing arm, causing the lower sealing plate to return to its original position and close, thus sealing the lower part of the feed hopper.

[0010] Furthermore, symmetrical swing arms are provided on both the left and right sides of the lower sealing plate, and a connecting rod connects the ends of the two sets of swing arms. A guide sleeve is provided on the back plate, located below the connecting rod. A guide rod is slidably connected in the guide sleeve, and a lower return spring is press-fitted between the bottom end of the guide rod and the guide sleeve. The top end of the guide rod is hinged to the middle of the connecting rod via a pull rod. This structural design makes the movement of the lower sealing plate more stable, improving the sealing reliability and service life of the lower sealing plate.

[0011] Furthermore, symmetrical limiting plates are provided on the back plate. The limiting plates are located below the through groove. The limiting plates are used to limit the rotation angle of the swing arm, prevent the swing arm from rotating excessively, and ensure the normal operation and sealing effect of the lower sealing plate.

[0012] Furthermore, a turntable is coaxially provided at the hinge of the lower sealing plate, and the through groove is adapted to the turntable. The turntable can seal the through groove to prevent garbage from clogging it and reduce the friction of the lower sealing plate during rotation, making the rotation of the lower sealing plate more flexible and smooth.

[0013] Furthermore, a guide plate is provided on the outer side of the upper sealing plate, and the guide plate is inclined outward. Side baffles are provided on the top of each side plate, and the left and right sides of the guide plate are slidably connected to the side baffles. The guide plate guides the waste to accumulate on the top of the upper sealing plate, preventing waste from falling to the outside and ensuring normal waste feeding.

[0014] Furthermore, a middle sealing plate is provided on the inner side of one set of upper sealing plates. The middle sealing plate is used to cover the gap between the two sets of upper sealing plates, which further improves the sealing performance of the top of the feed hopper and avoids motion interference between the two sets of upper sealing plates during operation.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. Excellent sealing performance: Through the double sealing design of the upper and lower sealing plates, combined with the reset action of the upper and lower reset springs, the feeding hopper can be effectively sealed before and after the garbage is fed, preventing odor emission, dust flying and the entry of external air, thus meeting environmental protection and equipment operation requirements.

[0017] 2. Smooth feeding: The unique structural design of the feeding hopper and the setting of the guide plate facilitate the smooth sliding and entry of garbage in the feeding hopper, avoiding garbage accumulation and jamming, and improving feeding efficiency.

[0018] 3. Stable and reliable operation: The upper and lower sealing plates have a reasonable motion structure design. Together with the guide column, guide rod, turntable and other components, the movement of the sealing plates is more stable and flexible, reducing wear and improving the service life and working stability of the sealing structure.

[0019] 4. Convenient maintenance: The sealing structure of this utility model has a simple overall design, and the components are easy to install and disassemble, which facilitates later maintenance and reduces operating costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Reference Figure 1-6 The above describes a novel feeding hopper sealing structure for municipal solid waste power generation, comprising a feeding hopper 1, an upper sealing plate 2, and a lower sealing plate 3.

[0030] The feed hopper 1 has vertical side plates symmetrically arranged on the left and right sides. Each set of side plates has an upper reset groove 11 symmetrically arranged on the front and rear parts. The upper reset groove 11 also includes a horizontal section and a vertical section. The horizontal section is inclined downward toward the middle of the side plate. The front and rear sides of the side plate are connected to the back plate through the front plate and the back plate respectively. The inclination of the back plate is greater than that of the front plate to prevent arching.

[0031] The upper sealing plate 2 has two sets and is symmetrically arranged on the front and rear sides of the top opening of the feed hopper 1. The left and right sides of the upper sealing plate 2 are symmetrically provided with traction columns 22 and guide columns 23. The traction columns 22 and guide columns 23 on the same side are slidably connected in the same upper reset groove 11. The traction column 22 is located outside the guide column 23. An upper reset spring 12 is connected between the traction column 22 and the side plate. The upper reset spring 12 is used to reset the sealing state of the upper sealing plate 2.

[0032] The lower sealing plate 3 is hinged to the lower part of the feed hopper 1. The hinge of the lower sealing plate 3 is close to the back plate. The lower sealing plate 3 is provided with a swing arm 31 at one end near the back plate. The back plate is provided with a through groove. The swing arm 31 extends out of the through groove and slides in the through groove. The end of the swing arm 31 is connected to the back plate through the lower return spring 6.

[0033] As one implementation method in this embodiment, to enhance the stability of the lower sealing plate 3 during movement, such as... Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, swing arms 31 are symmetrically provided on both the left and right sides of the lower sealing plate 3. A connecting rod 32 is connected between the ends of the two sets of swing arms 31. A guide sleeve 14 is provided on the back plate. The guide sleeve 14 is located below the connecting rod 32. A guide rod 4 is slidably connected in the guide sleeve 14. A lower return spring 6 is press-fitted between the bottom end of the guide rod 4 and the guide sleeve 14. The top end of the guide rod 4 is hinged to the middle part of the connecting rod 32 through a pull rod 5.

[0034] As one implementation method in this embodiment, to ensure a good sealing effect after the lower sealing plate 3 is reset, such as Figure 1 , Figure 3 , Figure 5 As shown, a limiting plate 13 is symmetrically provided on the back plate. The limiting plate 13 is located below the through groove and is used to limit the flip angle of the swing arm 31.

[0035] As one implementation method in this embodiment, to seal the through groove and improve the stability of the lower sealing plate 3 when it flips, such as... Figure 1 , Figure 3 , Figure 5 As shown, a turntable 30 is coaxially provided at the hinge of the lower sealing plate 3, and the through groove is adapted to the turntable 30.

[0036] As one implementation method in this embodiment, to ensure the efficiency of waste feeding, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 As shown, a guide plate 20 is provided on the outer side of the upper sealing plate 2. The guide plate 20 is inclined outward. The top of the side plate is provided with a side baffle 10. The left and right sides of the guide plate 20 are slidably connected to the side baffle 10.

[0037] As one implementation method in this embodiment, to avoid motion interference and enhance sealing, such as Figure 1 , Figure 4 , Figure 6 As shown, a middle sealing plate 21 is provided on the inner side of a set of upper sealing plates 2. The middle sealing plate 21 and another set of upper sealing plates 2 can overlap vertically. The middle sealing plate 21 is used to cover the gap between the two sets of upper sealing plates 2.

[0038] The working principle of this practical device is as follows: When domestic waste enters the waste incineration treatment equipment, the waste falls onto the upper sealing plate 2, exerting pressure on the upper sealing plate 2. This causes the traction column 22 and guide column 23 of the upper sealing plate 2 to slide downwards along the horizontal section of the upper reset groove 11. The guide column 23 first falls into the vertical section of the upper reset groove 11, and the traction column 22 moves accordingly, stretching the upper reset spring 12. At this time, the upper sealing plate 2 flips downwards and opens. As the guide column 23 falls a longer distance into the vertical section of the upper reset groove 11, the angle of the upper sealing plate 2 flips larger. The waste on the upper sealing plate 2 will slide down from the upper sealing plate 2 into the feed hopper 1 and fall onto the lower sealing plate 3. During this process, the guide plate 20 can receive the waste, and the side baffle 10 cooperates with the guide plate 20 to prevent the waste from falling out. After the waste passes through the upper sealing plate 2, the upper return spring 12 contracts, causing the traction column 22 to move upward and reset in the upper reset groove 11. When the traction column 22 moves to the top end of the upper reset groove 11, the guide column 23 also moves into the horizontal section of the upper reset groove 11, thereby resetting the upper sealing plate 2 and achieving a sealing effect. Under the gravity of the waste, the lower sealing plate 3 flips around the hinge, the turntable 30 rotates in the through groove, and the swing arm 31 flips accordingly, causing the connecting rod 32 to move. Then, through the pull rod 5, the guide rod 4 slides in the guide sleeve 14, compressing the lower return spring 6 until the swing arm 31 contacts the back plate, forming a limit. At this time, the lower sealing plate 3 flips downward to the limit position, and the waste falls into the equipment below for processing. After the waste passes through, the lower return spring 6 pulls the swing arm 31, causing the lower sealing plate 3 to reset and close, achieving a double-layer seal for the feed hopper 1. The limiting plate 13 restricts the rotation angle of the swing arm 31, the turntable 30 ensures the smooth rotation of the lower sealing plate 3, the middle sealing plate 21 improves the sealing performance of the upper sealing plate 2 and avoids motion interference. The coordinated work of each component ensures the normal operation of the sealing structure and a good sealing effect.
