Description

Technical Field

[0001] This invention relates to the field of metallurgical technology, and more specifically, to a dust collection device for coke ovens and its control method. Background Technology

[0002] A smoke guide car is a mechanical device used during the coal charging process in a tamping coke oven to guide the large amount of smoke and dust generated in the carbonization chamber into an adjacent final carbonization chamber. The adjacent carbonization chamber generates suction by switching between high and low pressure ammonia water to extract the smoke and dust. Currently, all smoke guide cars on the market have this function.

[0003] However, before the coal charging and flue gas guiding work begins, each carbonization chamber has a cooling procedure before coke discharge (that is, before coke is discharged from the coke oven, the riser cover needs to be opened to allow air to enter the carbonization chamber and burn off the graphite in the carbonization chamber). After the riser cover is opened, the smoke and dust are discharged into the atmosphere from the riser.

[0004] The dust collection devices used for the riser pipes of existing coke ovens are usually integrated into the flue gas car, resulting in a relatively large structure for the flue gas car and requiring strict control over the relative positional relationship between the dust collection device and the flue gas car. Taking the 5-2 series sequence as an example, when charging coal or the flue gas car for the Nth furnace, the cover-opening mechanism opens the cover of the N+5 furnace for ventilation. At this time, the dust collection device collects dust from the riser pipe of the N+5 furnace, and the dust collection path of the dust collection device for the coke oven is strictly limited.

[0005] For example, Chinese Patent Publication No. CN 114214078 A discloses a dust collection and fume extraction vehicle with an onboard dust removal device, comprising: a steel structure, a traveling device, a coke-side fume extraction pipe device, a machine-side fume extraction pipe device, a venting device, an air circuit system, a vehicle-mounted crane, a machine-side guide sleeve device, a driver's cab, a hydraulic chamber, an electrical chamber, an automatic alignment system, a temperature and pressure detection device, a sliding contact device, and a dust removal device; wherein the dust removal device of the aforementioned riser pipe operates at the fume outlet position above the riser pipe, collecting dust by suction. In this application, the dust removal device is fixedly installed on the fume extraction vehicle and moves synchronously with it, its dust removal path is strictly limited, and its flexibility is poor. Summary of the Invention

[0006] To address the technical problem of strictly limited dust removal paths in existing coke oven dust removal devices, this invention provides a novel coke oven dust removal device and its control method. This solution detaches the connection between the coke oven dust removal device and the top charging car or tamping flue car, allowing the dust removal device to move flexibly relative to the top charging car or tamping flue car without strictly limiting its relative position to the main steel structure. More importantly, it facilitates precise position control during the movement of the dust removal device and avoids interference between the dust removal device and the main steel structure during relative movement.

[0007] The first aspect of the present invention provides a dust collection device for coke ovens, the dust collection device comprising a steel structure support frame, wherein the connection between the steel structure support frame and the frame of the top-loading coal car or the tamping flue car is detachable; a dust collection mechanism disposed on the side of the steel structure support frame near the riser pipe; and a traveling mechanism installed on the lower part of the steel structure support frame for driving the steel structure support frame to travel along the ground rail.

[0008] Furthermore, the steel structure support frame is detachably connected to the frame of the top-loading coal car or the tamping smoke guide car through a hook mechanism.

[0009] Furthermore, the hook mounting frame is fixedly installed on the steel structure support frame, and the connecting rod assembly is rotatably installed on the hook mounting frame; the hook connecting frame is fixedly installed on the frame of the top-loading coal car or the tamping smoke guide car; and has a groove inside that is compatible with the connecting rod assembly; by the connecting rod assembly engaging or disengaging from the groove, a detachable connection between the structural support frame and the frame of the top-loading coal car or the tamping smoke guide car can be achieved.

[0010] Furthermore, the hook mounting bracket is provided with two hook connection side plates that are relatively spaced apart. The connecting rod assembly is located on the inner side of the two hook connection side plates. The connecting rod assembly includes two transmission rods that are spaced apart. The middle part of the two transmission rods is rotatably mounted between the two hook connection side plates through a rotating rod. One end of the transmission rod is fixedly connected to the hook connection bracket through a hook engaging rod, and the other end is fixedly connected through a connecting auxiliary rod. The hook engaging rod is used to engage or disengage from the interior of the groove.

[0011] Furthermore, a tension spring is provided between the transmission rod and the hook mounting bracket; a limiting rod is also provided on the inner side of the two hook connecting side plates, the limiting rod being used to limit the downward rotation angle of the end of the transmission rod near the hook connecting bracket; a slope is also provided on the side of the hook connecting bracket near the hook mounting bracket; the hook mating rod contacts the slope and slides along it to achieve the hook mating rod being engaged in the interior of the groove; a first telescopic drive member is also provided on the hook mounting bracket, the first telescopic drive member being used to drive the hook mating rod out of the interior of the groove.

[0012] Furthermore, the hook mechanism also includes a first detection component, which is used to detect whether the hook engagement rod is engaged in the groove; and / or the hook mechanism also includes a second detection component, which is used to detect whether the end of the transmission rod near the hook connecting frame is in contact with the slope.

[0013] Furthermore, the dust collection system includes a dust collector and a fume hood. The dust collector is fixedly installed on the side of the steel structure support frame near the riser pipe via a dust collection mounting bracket; the fume hood is located at the top of the riser pipe; and the fume hood and the dust collector are connected by a flue pipe.

[0014] Furthermore, the dust collection system also includes a tie rod assembly, which is disposed between the flue connecting pipe and the steel structure support frame to maintain the stability of the connection between the fume hood and the steel structure support frame.

[0015] Furthermore, the walking mechanism includes a walking motor, which drives the steel structure support frame to walk along the ground track through a transmission component, and a clutch is provided between the walking motor and the transmission component.

[0016] A second aspect of the present invention provides a control method for the aforementioned dust collection device for coke ovens, comprising: when the steel structure support frame in the dust collection device is connected to the frame of the top-loading coal car or the tamping guide car, the top-loading coal car or the tamping guide car drives the oven drying system to move synchronously along the ground rail; when the frame of the top-loading coal car or the tamping guide car is stationary, and the steel structure support frame in the oven drying system is separated from the frame of the top-loading coal car or the tamping guide car, a traveling mechanism drives the steel structure support frame in the oven drying system to travel along the ground rail, wherein the traveling mechanism uses the position of the top-loading coal car or the tamping guide car as a reference point for its traveling process.

[0017] Compared with the prior art, the technical solution provided by this invention has the following advantages: (1) The connection between the steel structure support frame and the frame of the tamping and flue gas guiding car in this invention is designed to be separable. That is, the connection between the coke oven dust collection device and the frame of the tamping and flue gas guiding car is designed to be separable. The steel structure support frame and the frame of the tamping and flue gas guiding car can be connected as a whole, and the tamping and flue gas guiding car pushes the steel structure support frame to travel along the ground rail; the steel structure support frame can also be separated from the frame of the tamping and flue gas guiding car. In this case, the steel structure support frame can travel along the ground rail under the drive of the traveling mechanism. Based on this, the dust collection path of the dust collection device is more flexible. This coke oven dust collection device is also suitable for top-loading coal cars.

[0018] (2) The present invention optimizes the control method of the dust collection device. Specifically, the coke oven dust collection device moves toward the tamping guide car and is connected to it as a whole. The starting position of the dust collection device is set to zero, that is, it uses the relative distance with the tamping guide car as the reference value for its movement distance, that is, it uses the position of the tamping guide car as the reference point, thereby facilitating the control of its movement along the ground rail. The coke oven dust collection device is also suitable for top-loading coal cars. Attached Figure Description

Detailed Implementation

[0024] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments.

[0025] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

[0026] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation. Furthermore, some of the above terms may be used to indicate other meanings besides orientation or positional relationship; for example, the term "upper" may in some cases indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0027] Regarding the following definitions of terms used in this invention: "Separable" refers to two objects that can be connected as a whole or separated into two parts; "the connection between the steel structure support frame 1 and the frame of the top-loading coal car or the tamping smoke guide car is separable" means that the connection between the steel structure support frame 1 and the frame of the top-loading coal car or the tamping smoke guide car can be combined into a whole, in which case the top-loading coal car or the tamping smoke guide car drives the steel structure support frame to move synchronously along the ground rail 4, or the two parts can be separated, in which case the steel structure support frame 1 can move along the ground rail 4 under the drive of the traveling mechanism 5, that is, the steel structure support frame 1 can move relative to the frame of the top-loading coal car or the tamping smoke guide car. Example 1

[0028] This embodiment provides a dust collection device for coke ovens. The dust collection device includes a steel structure support frame 1, which is detachably connected to the frame of the tamping and flue gas guiding car; a dust collection mechanism 3, which is located on the side of the steel structure support frame 1 near the riser pipe; and a traveling mechanism 5, which is installed on the lower part of the steel structure support frame 1 and is used to drive the steel structure support frame 1 to travel along the ground track 4.

[0029] It should be noted that if the dust collection device and the tamping and fume guide car are designed as two separate units that travel independently along the ground rail 4, i.e., they are separate designs, meaning they are two devices that travel independently along the ground rail 4. The tamping and fume guide car is generally operated by a driver, so its positional accuracy is relatively high. When this arrangement is adopted, the positional accuracy of the dust collection device needs to be controlled separately as it travels along the ground rail 4. In steel plants, the path of a single coke oven is generally long, and achieving long-distance and high-precision movement of the dust collection device inevitably leads to a more complex precision control system. At the same time, the on-site production environment is harsh, and the hardware of traditional control systems has limited environmental temperature adaptability, further increasing the requirements for the control system. In addition, the dust collection device and the tamping and fume guide car share the same ground rail during movement. When they travel relatively independently, it is also necessary to avoid interference between their movement trajectories, which further limits the range of dust collection operation that the dust collection device can perform on the riser pipe. Therefore, this arrangement has a high implementation cost and poor adaptability.

[0030] For the reasons mentioned above, the connection between the steel structure support frame 1 and the frame of the tamping and flue gas guiding car is designed to be separable. That is, the connection between the coke oven dust collection device and the frame of the tamping and flue gas guiding car is designed to be separable. The steel structure support frame 1 and the frame of the tamping and flue gas guiding car can be connected as a whole, and the tamping and flue gas guiding car pushes the steel structure support frame 1 to move along the ground rail 4. The steel structure support frame 1 can also be separated from the frame of the tamping and flue gas guiding car. In this case, the steel structure support frame 1 can move along the ground rail 4 under the drive of the walking mechanism 5, so that the distance between the dust collection device and the frame of the tamping and flue gas guiding car is more flexible.

[0031] When the tamping and flue gas guiding car guides the smoke from coke oven M, the dust collection device for that coke oven detaches from the tamping and flue gas guiding car and travels along the direction of travel on ground rail 4. The dust collection device can collect dust from the riser pipes of coke ovens M+10 or further back, without being limited by the fixed distance between the dust collection device and the frame of the tamping and flue gas guiding car. Before the tamping and flue gas guiding car completes its smoke guiding for coke oven M, the dust collection device moves towards the tamping and flue gas guiding car and connects with it as a whole. When the dust collection device moves towards the tamping and flue gas guiding car and connects with it as a whole, its initial position is reset to zero. That is, it uses the relative distance to the tamping and flue gas guiding car as a reference value for its movement distance, and the position of the tamping and flue gas guiding car as a reference point, thereby simplifying the control of its positional accuracy.

[0032] refer to Figure 3 , Figure 4 As shown, the steel structure support frame 1 and the frame of the tamping and smoke guiding vehicle are detachably connected via a hook mechanism 2. Using the hook mechanism 2 to achieve this detachable connection between the steel structure support frame 1 and the frame of the tamping and smoke guiding vehicle provides higher stability and simplifies the control process.

[0033] It should be noted that the specific implementation of the detachable connection between the steel structure support frame 1 and the frame of the tamping and smoke guiding vehicle is not limited to the hook mechanism 2 mentioned above, and it can also be achieved through other methods such as electromagnetic adsorption.

[0034] Specifically, the hook mechanism 2 includes a hook mounting frame 201, a hook connecting frame 203, a first telescopic drive component 202, and a connecting rod assembly 204. The hook mounting frame 201 is fixedly installed on the steel structure support frame 1, and the connecting rod assembly 204 is rotatably installed on the hook mounting frame 201. The hook connecting frame 203 is fixedly installed on the frame of the tamping smoke guide car, and has a groove 231 inside that is compatible with the connecting rod assembly 204, so as to realize the separable connection between the structural support frame 1 and the frame of the top-loading coal car or the tamping smoke guide car.

[0035] More preferably, the hook mounting bracket 201 is provided with two hook connecting side plates 211 that are relatively spaced apart. The connecting rod assembly 204 is located on the relatively inner side of the two hook connecting side plates 211. The connecting rod assembly 204 includes two spaced transmission rods 242. The middle part of the two rotating rods 241 is rotatably mounted between the two hook connecting side plates 211 through the rotating rods 241. One end near the hook connecting bracket 203 is fixedly connected by a hook engaging rod 244, and the other end is fixedly connected by a connecting auxiliary rod 243. The hook engaging rod 244 is used to engage or disengage from the interior of the groove 231.

[0036] The other ends of the two transmission rods 242 are fixedly connected by a connecting auxiliary rod 243, thereby improving the overall connection stability of the connecting rod assembly 204.

[0037] More preferably, the two ends of the rotating rod 241 are rotatably mounted on the two hook connecting side plates 211 via rolling bearings, and the middle parts of the two transmission rods 242 are fixedly sleeved on the outside of the two ends of the rotating rod 241.

[0038] In some embodiments, a tension spring 245 is also provided between the transmission rod 242 and the hook mounting bracket 201; a limiting rod 246 is also provided on the opposite inner side of the two hook connecting side plates 211, the limiting rod 246 is used to limit the downward rotation angle of the end of the transmission rod 242 near the hook connecting bracket 203; a slope 232 is also provided on the side of the hook connecting bracket 203 near the hook mounting bracket 201; the hook engaging rod 244 contacts the slope 232 and slides along it, so as to realize that the hook engaging rod 244 is engaged in the interior of the groove 231; a first telescopic drive member 202 is also provided on the hook mounting bracket 201, the first telescopic drive member 202 is used to drive the hook engaging rod 244 out of the interior of the groove 231.

[0039] The limiting rod 246 is used to limit the downward rotation angle of the end of the transmission rod 242 near the hook connecting frame 203. When the steel structure support frame 1 returns, if the downward angle of the transmission rod 242 is large, the bottom end of the hook engaging rod 244 will not be able to contact the slope surface 232 or slide along it, and thus the hook engaging rod 244 will collide with the hook connecting frame 203.

[0040] The tension spring 245 has two ends connected to the hook mounting bracket 201 and the end of the transmission rod 242 near the hook connecting bracket 203, respectively. By using the tension spring 245, not only can the smooth rotation of the transmission rod 242 be achieved and its disorderly rotation be restricted, but when the hook connecting bracket 203 is engaged in the groove 231, the tension spring 245 applies tension to the transmission rod 242, maintaining the relative stability of the transmission rod 242's angle and preventing the hook connecting bracket 203 from dislodging from the groove 231. When the hook connecting bracket 203 disengages from the groove 231 under the action of the first telescopic drive member 202, after the first telescopic drive member 202 is removed, the tension spring 245 drives the transmission rod 242 to rotate in the opposite direction to return to its original position.

[0041] The process of using the hook mechanism 2 to achieve a separable connection between the steel structure support frame 1 and the frame of the tamping smoke guide car is as follows: In the initial position, the hook engaging rod 244 in the hook mechanism 2 is located in the groove 231 in the hook mounting frame 201. The first telescopic drive member 202 drives the transmission rod 242 to rotate away from the groove 231 in the hook mounting frame 201. The hook engaging rod 244 rotates upward and leaves the groove 231 in the hook mounting frame 201. The traveling ground rail 7 drives the steel structure support frame 1 to move away from the frame of the tamping smoke guide car along the ground rail 6, thereby realizing the separation of the steel structure support frame 1 from the frame of the tamping smoke guide car. During the return journey, the traveling track 7 drives the steel structure support frame 1, which in turn moves the steel structure support frame 1 along the track 6 closer to the frame of the tamping and smoke guiding car. The bottom end of the hook engaging rod 244 contacts the slope surface 232 and slides upward along it. As the distance between the steel structure support frame 1 and the frame of the tamping and smoke guiding car gradually decreases, the hook engaging rod 244 moves to the top of the slope surface 232 and engages inside the groove 231. When the hook engaging rod 244 engages inside the groove 231, the tension spring 245 restricts the upward rotation of the end of the transmission rod 242 near the hook connecting frame 203, thereby preventing the hook mounting frame 201 from disengaging from the frame of the tamping and smoke guiding car.

[0042] As an extension, the first telescopic drive member 202 is preferably an electric cylinder, which is fixedly installed on the hook connection side plate 211 and located above the end of the transmission rod 242 away from the hook mating rod 244. The movable end of the first telescopic drive member 202 does not need to be fixedly connected to the transmission rod 242. The first telescopic drive member 202 extends out, contacts the transmission rod 242 and pushes the transmission rod 242 to rotate around one end, so that the hook mating rod 244 disengages from the interior of the groove 231.

[0043] Under the action of the tension spring 245 itself, the transmission rod 242 rotates in the opposite direction to return to its original position.

[0044] As a further extension, there are two tension springs 245, which are located on the opposite inner side of the two hook connecting side plates 211 and are symmetrically arranged relative to the two transmission rods 242.

[0045] To detect whether the hook-fitting rod 204 in the linkage assembly 204 is engaged inside the groove 231, the hook mechanism 2 further includes a first detection component 205. The first detection component 205 includes a first proximity sensor 251 and a first sensing plate 252. The first proximity sensor 251 is installed in the hook-fitting rod 244. Correspondingly, the hook connecting frame 203 is provided with a first sensing plate 252 for sensing by the first proximity sensor 251. Preferably, the top surface of the first sensing plate 252 is flush with the bottom surface of the groove 231 in the hook connecting frame 203. As the bottom end of the hook-fitting rod 244 contacts the slope 232 and slides upward along it, when the hook-fitting rod 244 is engaged inside the groove 231, the first proximity sensor 251 in the hook-fitting rod 244 senses the first sensing plate 252 in the hook connecting frame 203, thereby detecting that the hook-fitting rod 204 is engaged inside the groove 231.

[0046] In order to detect whether the end of the transmission rod 242 near the hook connection frame 203 is in contact with the slope 232, the hook mechanism 2 also includes a second detection component 206. The second detection component 206 also includes a second proximity sensor 261 and a second sensing plate 262. The second proximity sensor 261 is fixedly installed on the hook connection side plate 211, and the sensing end is set towards the transmission rod 242. The second sensing plate 262 is preferably arc-shaped and is fixedly installed on the side of the transmission rod 242 near the hook connection side plate 211.

[0047] When the hook engagement rod 204 disengages from the interior of the groove 231, the angle of the transmission rod 242 in the connecting rod assembly 204 remains relatively constant under the constraint of the tension spring 245. At this time, the second sensing plate 262 is directly facing the second proximity sensor 261. During the return trip of the traveling ground rail 7, that is, during the return trip of the steel structure support frame 1, the steel structure support frame 1 moves along the ground rail 6 closer to the frame of the tamping and guiding smoke car. The bottom end of the hook engagement rod 244 contacts the slope surface 232 and slides upward along it. During this process, one end of the transmission rod 242 near the hook connecting frame 203 gradually rotates upward, that is, the other end of the transmission rod 242 rotates downward. As a result, the second sensing plate 262 moves downward relative to the second proximity sensor 261 and leaves the sensing area of ​​the second proximity sensor 261. The control system of the automatic furnace cover opening and closing system receives the signal that the steel structure support frame 1 has begun to contact the frame of the tamping and guiding smoke car.

[0048] As a further preferred embodiment of any of the above embodiments, the dust collection system 8 includes a dust collector 306 and a fume hood 308. The dust collector 306 is fixedly mounted on the side of the steel structure support frame 1 near the riser pipe via a dust collection mounting bracket 307. The fume hood 308 is located at the top of the riser pipe. The fume hood 308 and the dust collector 306 are connected by a flue connecting pipe 305.

[0049] The smoke and dust escaping from the riser pipe are drawn in by the fume hood 308 and then enter the dust collector 306 through the flue connection pipe 305. The dust collector 306 removes dust from the flue gas, and the dust-removed gas is directly discharged.

[0050] As an extension, the dust collection system 8 also includes a tie rod assembly, which is disposed between the flue connection pipe 305 and the steel structure support frame 1 to maintain the stability of the connection between the fume hood 308 and the steel structure support frame 1.

[0051] As a further extension, the tie rod assembly is a triangular tie rod assembly.

[0052] Preferably, the pull rod assembly includes a first pull rod group 303 and a second pull rod group 304. One end of the first pull rod group 303 is fixedly connected to the top of the fume hood 308, and the other end of the first pull rod group 303 is hinged to a first support connecting seat 301 fixed to the steel structure support frame 1. One end of the second pull rod group 304 is hinged to the middle of the first pull rod group 303, and the other end of the second pull rod group 304 is hinged to a second support connecting seat 302 fixed to the steel structure support frame 1. The first support connecting seat 301 and the second support connecting seat 303 are spaced apart on the steel structure support frame 1, and the first support connecting seat 301 is located between the second support connecting seat 303 and the dust collector 306. The first pull rod group 303, the second pull rod group 304, and the first support connecting seat 301 and the second support connecting seat 302 together form a triangular pull rod assembly.

[0053] Further preferably, the first tie rod assembly 303 is a rectangular frame structure. Specifically, the first tie rod includes two opposing first tie rods, the two ends of which are connected by parallel connecting rods to form a rectangular frame structure. The two ends of the rectangular frame structure are respectively connected to the smoke hood 308 and the first support connecting seat 301; there are also multiple reinforcing connecting rods 331 between the two first tie rods to further improve the stability of the rectangular frame structure.

[0054] More preferably, the second tie rod assembly 304 includes two opposing second tie rods. One end of the two second tie rods 304 is hinged to the first tie rod via a reinforcing connecting rod 331 or a connecting rod in the first tie rod assembly 303, and the other end of the two second tie rods 304 is hinged to the first support connecting seat 301 via a connecting rod.

[0055] In a preferred embodiment, the traveling mechanism 5 includes a traveling motor. The traveling motor drives the steel structure support frame 1 to travel along the ground rail 4 via a transmission assembly. A clutch is provided between the traveling motor and the transmission assembly to disconnect or connect the power transmission between them. When the steel structure support frame 1 and the tamping and flue gas guiding car are connected as a whole, that is, when the furnace cooling system is driven by the tamping and flue gas guiding car, the power transmission between the traveling motor and the transmission assembly is disconnected, which helps to prevent wear on the traveling motor and the traveling wheels in the traveling mechanism 5.

[0056] When the steel structure support frame 1 in the dust collection device is connected to the frame of the tamping and flue gas guiding car, the tamping and flue gas guiding car drives the furnace cooling system to move synchronously along the ground rail 4. When the frame of the tamping and flue gas guiding car is stationary, and the steel structure support frame 1 in the furnace cooling system is separated from the frame of the tamping and flue gas guiding car, the traveling mechanism 5 drives the steel structure support frame 1 in the furnace cooling system to travel along the ground rail 4. The traveling mechanism 5 uses the position of the tamping and flue gas guiding car as a reference point for its traveling process, which facilitates the control of the position of the dust collection device during its traveling process and helps to improve the control accuracy. Example 2

[0057] The difference between this embodiment and Embodiment 1 is that the connection between the steel structure support frame 1 and the frame of the top-loading coal car is separable; the rest of the structure is basically the same, that is, the dust collection device is also suitable for top-loading coke ovens.

[0058] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
