[0031] The present invention is further described below in conjunction with the accompanying drawings and given embodiments, but is not limited thereto.

[0032] like Figure 1 , 2, 3, 4, 5, and 6, a mobile matrix casting area multi-point smoke collection device includes a mobile hood 1, a main smoke pipe 2, a mobile smoke main pipe 3, and a walking mechanism 4.

[0033] The mobile hood 1 is arranged on a casting foundation 9, and the two sides of the mobile hood 1 in the length direction are slidably matched with the casting foundation 9 through a walking mechanism 4. A plurality of sand boxes arranged in a matrix are arranged on the casting foundation. The mobile hood 1 is provided with a plurality of opening and closing mechanisms 5 for facilitating the entry and exit of the ladle, and an air suction hood 10 is arranged inside the mobile hood 1.

[0034] The top of the mobile hood 1 is provided with a mobile smoke main pipe 3 connected to the suction hood 10. The main smoking pipe 2 is supported on a column (not shown in the figure) of the poured foundation 9. The air outlet of the main smoking pipe 2 is connected to the dust removal equipment, and a plurality of connecting pipes 21 connected thereto are provided on the pipe body. Each connecting pipe 21 is provided with a first electric air valve 6 for controlling the opening and closing of the connecting pipe 21.

[0035] When pouring any sand box on the pouring foundation 9, the mobile hood 1 moves under the action of the walking mechanism 4 and is caged on the outer periphery of the corresponding sand box. At the same time, the mobile smoke exhaust pipe 3 on the mobile hood 1 forms a sealed connection with a docking pipe 21 on the main smoking duct 2, and the first electric air valve 6 provided on the docking pipe 21 is in an open state, and the first electric air valves 6 on the remaining docking pipes 21 are in a closed state. At this time, the smoke generated by the ladle enters the suction hood 10 and is transferred to the inside of the main smoking duct 2 through the mobile smoke exhaust pipe 3, so that the dust removal equipment sucks out the smoke in the main smoking duct 2 and dedusts and purifies it before discharging it.

[0036] like Figure 2 As shown, in order to prevent smoke from overflowing from the top and accelerate the smoke to enter the mobile smoke outlet pipe, thereby improving the smoking efficiency, a smoke blowing mechanism 7 is also included, wherein the smoke blowing mechanism 7 includes a fan 71, a blowing pipe 72, a blowing branch pipe 73 and an air curtain pipe 74. The fan 71 is arranged on the top of the mobile hood 1, and its air outlet is connected to the blowing pipe 72.

At the same time, the wind sprayed from the air outlet of the wind curtain pipe 74 forms a wind curtain and is arranged opposite to the air intake of the suction hood 10. The smoke generated during pouring is accelerated to enter the interior of the suction hood 10 under the action of the smoke blowing mechanism 7. Specifically, the wind blown by the fan 71 enters the wind curtain pipe 74 through the wind blowing main pipe 72 and the wind blowing branch pipe 73, and the wind sprayed by the wind curtain pipe 74 forms a wind curtain, which accelerates the rising smoke into the mobile smoke removal main pipe, greatly improving the smoking efficiency.

[0037] like Figure 1 ,3 As shown, in order to adapt to different working conditions and save energy and protect the environment, the mobile smoke main pipe 3 is provided with two groups of transfer pipes 31 arranged symmetrically along it, and each transfer pipe 31 is provided with a second electric air valve 32. The interior of the mobile hood 1 is provided with an air suction hood 10 with two air suction ports arranged opposite to each other. The two transfer pipes 31 of each group are respectively connected with one air suction port of the corresponding air suction hood 10. Specifically, the air suction hood has two air suction ports, which are connected with the corresponding transfer pipes 31. When pouring into any one of the sand boxes, the second electric air valve 32 on the corresponding transfer pipe 31 above the sand box can be opened and connected with the air suction port corresponding to the air suction hood 10. If pouring into multiple sand boxes at the same time, the corresponding second electric air valve can be opened as needed to make the overall smoke collection power more matched, so that the performance of the utility model is better. By adjusting the second electric air valve, not only the air volume conditions can be achieved, but also the on-off of a transfer pipe can be achieved.

[0038] like Figure 1 , 3 As shown, in order to simultaneously pour any one or more of the sand boxes and facilitate the hoisted ladle to enter the interior of the mobile hood, each opening and closing mechanism 5 is provided with a top opening and closing group and a side opening and closing group.

[0039] The top opening and closing group includes a first cylinder seat 51, a first cylinder 52 and a first door 53. The first door 53 is arranged at the opening of the top of the mobile hood 1 and is hingedly connected thereto. The first cylinder seat 51 is fixed to the top of the mobile hood 1. The body of the first cylinder 52 is rotatably connected to the first cylinder seat 51. The top rod is rotatably connected to the first door 53.

[0040] The side opening and closing group includes a second cylinder seat 54, a second cylinder 55, a second door 56 and a protective cover 57. The second door 56 is arranged at the opening on the side of the mobile hood 1 and is hingedly connected thereto, and the first door 53 and the second door 56 are combined into an L-shaped layout. The second cylinder seat 54 is fixed to the side of the mobile hood 1, the body of the second cylinder 55 is rotatably connected to the second cylinder seat 54, the push rod is rotatably connected to the second door 56, and the protective cover 57 covers the outer periphery of the body of the second cylinder 55 and is detachably connected to the mobile hood 1. Specifically, when pouring into any one or more of the sand boxes, the corresponding top first door 53 and the side second door 56 on the mobile hood 1 are opened by the cylinder to facilitate the hoisted ladle to enter the interior of the mobile hood 1 and be located above the corresponding sand box, and then the side second door 56 is closed, and the first door 53 is kept in an open state to prevent smoke from overflowing from the second door 56. The wind curtain formed by the wind sprayed from the wind curtain pipe 74 also has the possibility of preventing smoke from overflowing from the first door 53, thereby further improving the overall smoke capture efficiency.

[0041] Further, such as Figure 1 ,3 As shown, the mobile machine hood 1 of the utility model is respectively provided with two sets of opening and closing mechanisms on both sides in the length direction, with a total of four sets of opening and closing mechanisms 5. That is to say, at most four ladles can be hoisted into the mobile machine hood 1 at one time and four sand boxes can be poured. Two suction hoods 10 are provided in the mobile machine hood 1, and each suction hood 10 has two suction ports, which can collect the smoke generated when two ladles are poured at the same time. If only a single sand box is poured, the second electric air valve connected to the other suction port can be closed, so that one suction port in the suction hood 10 above the sand box can collect the smoke in a centralized manner, making the utility model more energy-saving and environmentally friendly.

[0042] like Figure 4 , 5 As shown, in order to ensure the sealing and accuracy when the mobile smoke exhaust pipe is docked with the docking pipe, a sealing docking mechanism 8 is provided on each docking pipe 21 on the main smoking pipe 2, and the sealing docking mechanism 8 includes a third cylinder 81, a telescopic pipe 82, a limit plate 83 and a limiter 84. The docking pipe 21 is slidably matched with the telescopic pipe 82 through the wear-resistant pipe provided inside, and the third cylinder 81 is fixed on both sides of the docking pipe 21 and a limiter seat 85 is provided on the top. The limiter 84 is installed on the limiter seat 85, and the top rod of the third cylinder 81 is fixedly connected to the end of the telescopic pipe 82. The mobile smoke exhaust pipe 3 is provided with a limit plate 83. When the mobile hood 1 moves into place and the limiter 84 sends a corresponding signal, the mobile hood 1 can stop moving. At this time, the third cylinder 81 is driven to act, and the telescopic pipe 82 is driven to extend to form a sealed dock with the end of the mobile smoke exhaust pipe 3. At the same time, the first electric air valve 6 on the docking pipe 21 is in an open state. The wear-resistant tube is preferably a wear-resistant PTFE tube. A silicone pad is provided at the end of the movable smoke exhaust pipe 3 to ensure the sealing between the movable smoke exhaust pipe 3 and the telescopic pipe 82. Of course, in order to further improve the sealing, a sealing pad can also be provided at the end of the telescopic pipe 82.

[0043] like Figure 1 , 6 As shown, in order to facilitate the efficient and accurate movement of the mobile hood to different sand box positions for docking, the walking mechanism 4 includes guide rails 41, end beams 42, track wheels 43 and walking motors 44. Two sets of guide rails 41 are provided on the casting foundation, and end beams 42 are provided on the bottom of both sides of the mobile hood 1, and track wheels 43 rotatably connected thereto are provided at both ends of the end beams 42. The track wheels 43 are rotatably matched with the corresponding guide rails 41 on the casting foundation, and the walking motor 44 is transmission-connected to the track wheel 43 at one end of the end beams 42.

[0044] like Figure 6As shown, in order to further improve the linearity and stability of the movement of the mobile hood, guide mechanisms are respectively provided at both ends of the end beam 42, and the guide mechanisms include an end plate 45 and a guide wheel 46. The end plate 45 is fixed to the end of the end beam 42, and two guide wheels 46 are rotatably connected to the end plate 45 at the bottom, and the guide wheels 46 are rotatably matched with the guide rail 41.

[0045] like Figure 6 As shown, in order to prevent the side of the movable hood from colliding with foreign objects, an anti-collision block 47 is further provided on the outer side wall of the end plate 45.

[0046] like Figure 1 As shown, in order to match the actual structure of the pouring foundation and to be more reasonable, to prevent the mobile hood from interfering with the surroundings and to make subsequent sand box transfer and other operations difficult, a set of guide rails 41 is provided at one end of the pouring foundation and a guide rail column 48 is provided at the other end, and another set of guide rails 41 is fixed on a fixed platform 481 of the guide rail column 48.

[0047] like Figure 1 , 2 As shown, in order to further improve the rationality of the movable hood structure, the movable hood includes a supporting frame, a top plate 11 arranged on the top of the supporting frame, a long vertical plate 12 and a short vertical plate 13 on both sides of the length direction, and side plates 14 on both sides of the width direction.

[0048] The specific working process of the utility model is:

[0049] The main smoke pipe 2 is connected to the air inlet of the dust removal equipment. When pouring is required, according to the position of the pouring sand box, the movable hood 1 is driven by the walking motor 44 to make the track wheel 43 roll along the guide rail 41 to the corresponding position and stop. When the movable hood 1 moves to the corresponding position and the limiter 84 sends a corresponding signal, the movable hood 1 can stop moving. At this time, the third cylinder 81 is driven to operate and drive the telescopic tube 82 to extend and form a sealed docking with the end of the movable smoke main pipe 3. At the same time, the first electric air valve 6 on the docking pipe 21 is in an open state, and the first electric air valves 6 on the remaining docking pipes 21 are in a closed state.

[0050] Open the first door 53 and the second door 56 corresponding to the top and side of the mobile hood 1, so that the hoisting mechanism (electric hoist) can hook the ladle into the mobile hood 1 and place it above the corresponding sand box. Then close the second door 56 on the side and keep the first door 53 in the open state to prevent the first door from interfering with the wire rope of the hoisting mechanism after closing.

[0051] As needed, open the second electric valve connected to the suction hood 10, and close the second electric air valve connected to another suction port, so that one suction port in the suction hood 10 above the sand box can collect smoke in a centralized manner.

[0052] When pouring the ladle, the smoke generated by the ladle will not diffuse in the environment, but will be covered in the mobile hood 1 and transferred to the main smoking duct 2 through the mobile smoke main pipe 3, so that the dust removal equipment can suck out the smoke in the main smoking duct 2 and purify it.

[0053] To sum up, since the utility model is provided with a movable machine hood on the periphery of the pouring sand box, the smoke generated during the pouring process will be covered inside the mobile machine hood, replacing the situation in the prior art where the smoke escapes due to rising when the sand box is poured and is directly exposed to the environment. At the same time, if sand boxes at different positions on the pouring foundation are poured, the mobile machine hood can be moved under the action of the walking mechanism to realize the switching of the smoking position, ensuring that the sand box pouring at any position can effectively capture the smoke. The position where the mobile machine hood of the utility model stays can capture the smoke generated by up to four pouring sand boxes at a time.

[0054] Therefore, the utility model can move back and forth to switch the smoke collection point, realize multi-point smoke collection, and can effectively prevent smoke diffusion, thereby improving the smoke collection efficiency.

[0055] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
