Description

Technical Field

[0001] The utility model belongs to the field of carbonization furnaces, and in particular relates to a manhole structure of a carbonization furnace. Background Art

[0002] The carbonization furnace is used to carbonize sludge. During the carbonization process, the carbonization furnace will be in a high temperature state, which will evaporate the water in the sludge while maximally retaining the carbon value in the sludge. The organic matter in the sludge is carbonized, and the sludge after carbonization can be recycled for secondary use. The volume of the sludge after carbonization becomes smaller, and there is no toxic gas, etc., which will not cause secondary pollution. Therefore, during the sludge carbonization process, it is necessary to ensure that the temperature in the carbonization furnace reaches a certain value to achieve the transformation of the sludge.

[0003] In order to facilitate the maintenance of the carbonization furnace, a manhole structure is usually opened at the carbonization furnace. The manhole structure is an open structure for personnel to enter and exit the equipment for installation, maintenance and safety inspection. It can also play an emergency role. Gas is also generated during the carbonization process. Therefore, when the pressure in the carbonization furnace is too high due to unexpected reasons, the gas can be discharged. However, due to the high temperature conditions during the carbonization process, when the manhole structure is opened, the surrounding environment will also rise, which may easily cause danger to personnel. In addition, during daily maintenance, since the manhole structure is usually set at the top, personnel are required to climb to the height corresponding to the manhole structure before opening the manhole structure, which will also increase the burden on personnel. Utility Model Content

[0004] In view of the above-mentioned deficiencies, the utility model provides a manhole structure of a carbonization furnace, which can keep an operator away from the manhole structure during the cover opening process.

[0005] The utility model is realized by the following technical solutions:

[0006] A manhole structure of a carbonization furnace, the carbonization furnace comprises a furnace body, the manhole structure comprises a cylinder embedded in the upper side of the furnace body and a cover body covered on the cylinder body, the cylinder body is a hollow structure and is fixed to the furnace body by a flange, and the cover body is hingedly connected to the cylinder body; the manhole structure also comprises a driving assembly for driving the cover body to rotate around the cylinder body, the driving assembly comprises a transmission member connected to the side wall of the furnace body and a connecting member connecting the transmission member and the cover body, the transmission member can move in a vertical direction away from the cover body to drive the cover body to rotate around the cylinder body through the connecting member; the driving assembly also comprises a driving member connected to the transmission member to drive the transmission member to move. When the cover body needs to be opened, the opening of the cover body is realized by driving the driving member located at the side wall and the transmission of the transmission member and the connecting member, that is, the cover body can be opened at a position away from the cover body, which can avoid danger to personnel when deflation is performed, and at the same time, it is more convenient to open the cover body during maintenance, and when personnel climb around the cover body, they can directly enter the furnace body through the cylinder body.

[0007] Furthermore, the driving member includes a toothed member provided with a first tooth and a fixed plate supporting the toothed member, the fixed plate is fixed to the side wall of the furnace body, and the transmission member is provided with a second tooth meshing with the first tooth on the side facing the driving member. The first tooth in the toothed member can mesh with the second tooth at the transmission member, so when the toothed member rotates, the first tooth and the second tooth are continuously meshed, thereby converting the rotation of the toothed member into the vertical movement of the transmission member, and then driving the cover body to rotate around the cylinder body through the connecting member; it can be understood that the driving member and the transmission member can also be selected as other structures, for example, the driving member is a cylinder member, and the cylinder rod is connected to the transmission member, which can also drive the transmission member to move in the vertical direction.

[0008] Furthermore, the driving member further comprises a handle connected to the latching tooth member, and the handle can drive the latching tooth member to rotate circumferentially. By providing the handle, the rotation of the latching tooth member can be facilitated, so that when a person rotates the latching tooth member, the first latching tooth will not be touched, thereby avoiding scratches.

[0009] Furthermore, the driving member also includes a limit block between the fixed plate and the latching tooth member, and the handle can also drive the latching tooth member to move in a direction close to the fixed plate, and a limit groove corresponding to the limit block is formed on the inner side of the fixed plate. When the latching tooth member needs to be rotated by the handle, the limit block is located between the fixed plate and the latching tooth member, and the limit block will not be limited at this time. When the handle drives the latching tooth member to rotate and open the cover body, the handle can be pushed at this time, so that the handle and the latching tooth member move together, and the limit block is engaged in the limit groove. At this time, the limit groove can be moved by the limit block, thereby limiting the rotation of the handle and preventing the cover body from returning to its original position. It can ensure that the cover body is always kept in an open state during the maintenance process, and more effectively protect the personnel entering the furnace body.

[0010] Further, the transmission member includes a first transmission section located at one side of the driving member and a second transmission section connected to the first transmission section, the second transmission section is located at the upper side of the cover, and the connecting member is connected to the second transmission section. The first transmission section is located at one side of the driving member, so it is convenient to cooperate with the driving member, and the second transmission section is located at the upper side of the cover, so it is convenient to cooperate with the cover located at the top of the furnace body, thereby achieving better transmission and facilitating the cover body to rotate through the driving member.

[0011] Furthermore, a rotating wheel connected to the connecting member is provided at the end of the second transmission section. Since the moving track of the cover body is an arc when the connecting member drives the cover body to rotate, by providing a rotating wheel at the second transmission section, when the cover body moves, the position of the connecting member can be adjusted during the rotation of the cover body, thereby preventing a jamming phenomenon when the cover body is driven to rotate.

[0012] Furthermore, the end of the second transmission section is recessed to form a groove for arranging the rotating wheel, and the connection between the connecting member and the rotating wheel is located in the groove. Since the connecting member is connected to the rotating wheel, a groove is arranged at the end of the second transmission section, so that the rotating wheel is located in the groove, and accordingly, the connection between the connecting member and the rotating wheel is also located in the groove, and the connecting member is limited by the side wall of the groove to prevent the connecting member from swinging during operation, so as to better rotate the cover body.

[0013] Furthermore, a handle is provided on the top wall of the cover body, and the number of the handles is two, and the connecting piece is connected to each handle. By providing a handle on the top wall of the cover body, it is convenient to connect the connecting piece to the handle, and then lift the cover body. At the same time, the number of the handles is two, and the force on the cover body is more stable when lifting the cover body.

[0014] Furthermore, the handle is located on the side of the cover body away from the driving member, and the hinged part of the cover body and the cylinder body is located on the side of the cover body close to the driving member. Since the cover body and the cylinder body are hinged, the handle is located on the side of the cover body away from the driving member, and the hinged part of the cover body and the cylinder body is located on the side of the cover body close to the driving member. When the cover body rotates, it will rotate toward the driving member, thereby facilitating the cover body to be turned up.

[0015] Furthermore, each connector is sleeved on the corresponding handle so that each connector can slide along the corresponding handle. The connector is sleeved on the corresponding handle to achieve the cooperation between the connector and the handle. At the same time, the sleeve connection enables the connector to slide along the corresponding handle. When the connector drives the handle to move, the connector can slide on the handle, thereby adjusting the position with the handle, so that the cover body can rotate more smoothly.

[0024] In addition, it should be noted that the dynamic terms such as "relative motion" mentioned in the embodiments of the present invention are not only changes in position, but also include movements such as rotation and rolling where there is no relative change in position but a change in state.

[0025] Finally, it should be noted that when a component is referred to as being "located" or "set on" another component, it can be on the other component or there can be an intermediate component at the same time. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there can be an intermediate component at the same time.

[0026] like Figures 1 to 4The manhole structure of a carbonization furnace is shown. The carbonization furnace is used to carbonize sludge. During the carbonization process, the carbonization furnace is in a high temperature state, which allows the water in the sludge to evaporate while retaining the carbon value in the sludge to the maximum extent. The organic matter in the sludge is carbonized, and the carbonized sludge can be recycled for secondary use. The volume of the carbonized sludge becomes smaller, and there is no toxic gas, etc., which will not cause secondary pollution. Therefore, during the sludge carbonization process, it is necessary to ensure that the temperature in the carbonization furnace reaches a certain value to achieve the transformation of the sludge. The carbonization furnace includes a furnace body 1, and the material is placed in the furnace body 1 for carbonization. The manhole structure is an open structure for personnel to enter and exit the equipment for installation, maintenance and safety inspection. It can also play an emergency role. Gas is also generated during the carbonization process. Therefore, when the pressure in the furnace body 1 is too high due to unexpected reasons, the gas can be discharged. However, due to the high temperature conditions during the carbonization process, when the manhole structure is opened, the surrounding environment will also rise, which may easily cause danger to personnel. In addition, during daily maintenance, since the manhole structure is usually set at the top, personnel are required to climb to the height corresponding to the manhole structure before opening the manhole structure, which will also increase the burden on personnel.

[0027] In the present application, the manhole structure includes a cylinder 2 embedded in the upper side of the furnace body 1 and a cover 3 covering the cylinder 2. The cylinder 2 is a hollow structure and is fixed to the furnace body 1 by a flange, and the cover 3 is hingedly connected to the cylinder 2; the manhole structure also includes a driving assembly for driving the cover 3 to rotate around the cylinder 2, and the driving assembly includes a transmission member 4 connected to the side wall of the furnace body 1 and a connecting member 6 connecting the transmission member 4 and the cover 3. The transmission member 4 can move in the vertical direction away from the cover 3 to drive the cover 3 to rotate around the cylinder 2 through the connecting member 6; the driving assembly also includes a driving member 5 that is transmission-connected to the transmission member 4 to drive the transmission member 4 to move; the cover 3 is hingedly connected to the cylinder 2, so that the cover 3 can rotate compared to the cylinder 2, thereby realizing the opening and closing of the cover 3, and the cylinder 2 is a hollow structure. The structure is such that after the cover body 3 is opened, the interior of the furnace body 1 can be connected with the outside through the cylinder 2, and the driving assembly in the present application comprises a transmission member 4 located at the side wall of the furnace body 1 and a connecting member 6 connecting the transmission member 4 and the cover body 3. The transmission member 4 can be driven by the driving member 5, so the driving member 5 is also located at the side wall of the furnace body 1. When it is necessary to open the cover body 3, it is only necessary to drive the driving member 5 located at the side wall and realize the opening of the cover body 3 through the transmission of the transmission member 4 and the connecting member 6, that is, the cover body 3 can be opened at a position away from the cover body 3, which can avoid danger to personnel when deflation is performed, and at the same time, it is more convenient to open the cover body 3 during maintenance. When personnel climb around the cover body 3, they can directly enter the interior of the furnace body 1 through the cylinder 2.

[0028] It can be understood that since the manhole structure can connect the outside world with the inside of the furnace body 1, when the manhole structure does not need to be started, the manhole structure needs to be sealed. Usually, a sealing structure is provided at the manhole structure to prevent the cover body 3 from being easily separated from the cylinder body 2. For the present application, it can operate the driving member 5 to finally drive the cover body 3 to rotate through the connecting member 6. However, for the previous operations, such as releasing the seal at the manhole structure, personnel are required to operate, while the present application can perform the final opening action, especially during the deflation process, which can prevent personnel from being exposed to high-temperature gas during the opening process.

[0029] In the present application, the driving member 5 includes a toothed member 51 provided with a first tooth 511 and a fixed plate 52 supporting the toothed member 51, the fixed plate 52 is fixed to the side wall of the furnace body 1, and the transmission member 4 is provided with a second tooth 43 meshing with the first tooth 511 on the side facing the driving member 5; the first tooth 511 in the toothed member 51 can mesh with the second tooth 43 at the transmission member 4, so when the toothed member 51 rotates, the first tooth 511 is continuously meshed with the second tooth 43, so that the rotation of the toothed member 51 is converted into the vertical movement of the transmission member 4, and then the cover body 3 is driven to rotate around the cylinder body 2 through the connecting member 6; it can be understood that the driving member 5 and the transmission member 4 can also be selected as other structures, for example, the driving member 5 is a cylinder member, and the cylinder rod is connected to the transmission member 4, which can also drive the transmission member 4 to move in the vertical direction.

[0030] Preferably, the driving member 5 also includes a handle 53 connected to the latch tooth member 51, and the handle 53 can drive the latch tooth member 51 to rotate in the circumferential direction; by providing the handle 53, the rotation of the latch tooth member 51 can be facilitated, so that people will not contact the first latch tooth 511 when rotating the latch tooth member 51, thereby avoiding scratches.

[0031] As an embodiment of the present application, the driving member 5 also includes a limit block 54 located between the fixed plate 52 and the latching tooth member 51, and the handle 53 can also drive the latching tooth member 51 to move in a direction close to the fixed plate 52. A limit groove corresponding to the limit block 54 is formed on the inner side of the fixed plate 52; when it is necessary to rotate the latching tooth member 51 through the handle 53, the limit block 54 is located between the fixed plate 52 and the latching tooth member 51, and the limit block 54 will not be limited at this time. When the handle 53 drives the latching tooth member 51 to rotate and open the cover body 3, the handle 53 can be pushed at this time, so that the handle 53 moves together with the latching tooth member 51, and the limit block 54 is engaged in the limit groove. At this time, the limit groove can be moved by the limit block 54, thereby limiting the rotation of the handle 53, avoiding the cover body 3 from returning to its original position, and ensuring that the cover body 3 always remains in an open state during the maintenance process, thereby more effectively protecting the personnel entering the furnace body 1.

[0032] It can be understood that since the handle 53 will drive the latching tooth part 51 to rotate, the part located between the fixed plate 52 and the latching tooth part 51 will also rotate accordingly, that is, the limit block 54 will also rotate. Therefore, when limiting, in order to ensure that the limit block 54 can be smoothly connected to the limit groove, the position of the limit block 54 can be set according to the angle of the handle 53 when the cover body 3 is opened during processing, and the position of the limit block 54 can be set to the position corresponding to the limit groove at this time. In subsequent operations, it is only necessary to clamp the cover body 3 and make some fine adjustments to achieve that after the cover body 3 is opened, the limit block 54 can be smoothly extended into the limit groove.

[0033] As an embodiment of the present application, the transmission member 4 includes a first transmission section 41 located on one side of the driving member 5 and a second transmission section 42 connected to the first transmission section 41, the second transmission section 42 is located on the upper side of the cover body 3, and the connecting member 6 is connected to the second transmission section 42; the first transmission section 41 is located on one side of the driving member 5, so it is convenient to cooperate with the driving member 5, and the second transmission section 42 is located on the upper side of the cover body 3, so it can be convenient to cooperate with the cover body 3 located on the top of the furnace body 1, thereby achieving better transmission and facilitating the cover body 3 to rotate through the driving member 5.

[0034] Among them, since the driving member 5 is composed of a toothed member 51 with a first toothed member 511 , and the transmission member 4 is provided with a second toothed member 43 meshing with the first toothed member 511 , specifically, the second toothed member 43 is provided at the first transmission section 41 .

[0035] Preferably, a rotating wheel 44 connected to the connecting member 6 is provided at the end of the second transmission section 42; since the movement trajectory of the cover body 3 is an arc when the connecting member 6 drives the cover body 3 to rotate, by providing a rotating wheel 44 at the second transmission section 42, when the cover body 3 moves, the position of the connecting member 6 can be adjusted during the rotation of the cover body 3, thereby preventing jamming when driving the cover body 3 to rotate, and the length of the connecting member 6 is constant, so even if a rotating wheel 44 is provided, after the cover body 3 is opened, the cover body 3 will not drive the connecting member 6 to move.

[0036] Preferably, the end of the second transmission section 42 is recessed to form a groove for setting the rotating wheel 44, and the connection between the connecting member 6 and the rotating wheel 44 is located in the groove; because the connecting member 6 is connected to the rotating wheel 44, a groove is set at the end of the second transmission section 42, so that the rotating wheel 44 is located in the groove, and accordingly, the connection between the connecting member 6 and the rotating wheel 44 is also located in the groove, and the connecting member 6 is limited by the side wall of the groove to prevent the connecting member 6 from swinging during operation, so as to better rotate the cover body 3.

[0037] As an embodiment of the present application, a handle 31 is provided on the top wall of the cover body 3, and the number of the handles 31 is two, and the connecting member 6 is respectively connected to each handle 31; by providing a handle 31 on the top wall of the cover body 3, it is convenient to connect the connecting member 6 to the handle 31, and then lift the cover body 3. At the same time, the number of the handles 31 is two, and when the cover body 3 is lifted, the force on the cover body 3 is more stable.

[0038] Preferably, the handle 31 is located on the side of the cover body 3 away from the driving member 5, and the hinge between the cover body 3 and the cylinder body 2 is located on the side of the cover body 3 near the driving member 5; since the cover body 3 is hinged to the cylinder body 2, the handle 31 is located on the side of the cover body 3 away from the driving member 5, and the hinge between the cover body 3 and the cylinder body 2 is located on the side of the cover body 3 near the driving member 5, when the cover body 3 rotates, it will rotate toward the side of the driving member 5, thereby facilitating the cover body 3 to be turned up.

[0039] In the present application, each connecting member 6 is sleeved on the corresponding handle 31 so that each connecting member 6 can slide along the corresponding handle 31; the connecting member 6 is sleeved on the corresponding handle 31 to achieve the cooperation between the connecting member 6 and the handle 31, and the sleeve connection enables the connecting member 6 to slide along the corresponding handle 31. When the connecting member 6 drives the handle 31 to move, the connecting member 6 can slide at the handle 31, thereby adjusting the position with the handle 31, so that the cover body 3 is smoother when rotating.
