Description

Technical Field

[0001] The invention relates to the technical field of casting equipment, in particular to a material discharging structure and a material discharging system. Background Art

[0002] When the casting mold is buried, it is necessary to place the sand mold in the insulation box, and fill the mold with sand and balls around it for compaction. When the mold is buried, the insulation box containing the sand mold is placed under the silo to collect sand and balls for burying. Because the sand mold is placed in the insulation box, the insulation sand and balls will accumulate in the middle when they are placed in the insulation box, and cannot be evenly distributed around the sand mold. Every time a part of the sand and balls are placed, the sand and balls must be manually flattened around the insulation box, which is inefficient. And because the insulation boxes are of different heights, sand and balls fall directly from a high place to the plate covering the sand mold in the middle of the insulation box, which is easy to raise dust and bounce sand balls. The dust treatment is not ideal, and there are many sand and balls on the ground, which need to be cleaned frequently. Summary of the invention

Since the middle cover body is sleeved outside the inner cover body and the outer cover body is sleeved outside the middle cover body, the first functional channel and the second functional channel are both arranged around the mold. Therefore, the ball sand can be evenly distributed around the mold when entering the insulation box, and there will be no uneven distribution of the ball sand, which has a better insulation effect on the mold. When one of the first functional channel and the second functional channel is used as a discharge channel for discharging the ball sand, the other can be used as a dust suction channel to extract the dust generated in the process of the ball sand entering the insulation box, which can greatly reduce the cleaning work and reduce dust pollution.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0023] like Figure 1 As shown, an embodiment discloses a discharge structure, including an inner cover body 100, a middle cover body 200 and an outer cover body 300, the inner cover body 100 is used to cover at least the casting port of the mold, the middle cover body 200 is sleeved outside the inner cover body 100, and a first functional channel 11 is formed between the middle cover body 200 and the inner cover body 100, the outer cover body 300 is sleeved outside the middle cover body 200, and a second functional channel 12 is formed between the outer cover body 300 and the middle cover body 200, one of the first functional channel 11 and the second functional channel 12 is a discharge channel, and the other is a dust suction channel.

[0024] According to the above-mentioned discharge structure, after the mold is placed in the insulation box, the inner cover body 100 can at least cover the casting port of the mold, and then the ball sand can be transported into the insulation box through the first functional channel 11 or the second functional channel 12. Since the casting port of the mold is covered at this time, the ball sand will not fall into the mold and will not affect the subsequent casting. Since the middle cover body 200 is sleeved on the outside of the inner cover body 100 and the outer cover body 300 is sleeved on the outside of the middle cover body 200, the first functional channel 11 and the second functional channel 12 are both arranged around the mold. Therefore, the ball sand can be evenly distributed around the mold when entering the insulation box, and there will be no uneven distribution of the ball sand, which has a better insulation effect on the mold. When one of the first functional channel 11 and the second functional channel 12 is used as a discharge channel for discharging the ball sand, the other can be used as a dust suction channel to extract the dust generated in the process of the ball sand entering the insulation box, which can greatly reduce the cleaning work and reduce dust pollution.

[0025] Optionally, a fan may be connected to the dust suction channel to remove the dust.

[0026] Optionally, the discharge channel forms an annular channel around the inner cover body 100, which can ensure that the ball sand is evenly distributed when the ball sand is discharged.

[0027] In one embodiment, if Figure 1As shown, the first functional channel 11 is a discharge channel, and the second functional channel 12 is a dust collection channel. At this time, the dust collection channel is located at the outermost layer of the discharge structure, which can further prevent the ball sand from falling outside the insulation box when the ball sand is sent into the insulation box, and the dust will be sucked away by the dust collection channel during the process of moving outside the insulation box, which has a better effect of reducing dust pollution.

[0028] Among them, the suction force of the dust suction channel should be smaller than the suction force that can suck the ball sand and other thermal insulation materials into the dust suction channel, so as to prevent the ball sand and other thermal insulation materials from being sucked into the dust suction channel.

[0029] In other embodiments, the first functional channel 11 may be set as a dust suction channel, and the second functional channel 12 may be set as a material discharge channel.

[0030] In one embodiment, if Figure 1 As shown, the two ends of the first functional channel 11 are respectively a material inlet 11a and a material outlet 11b, and the inner cover body 100 includes a first segment 110 and a second segment 120 connected to each other, and the first segment 110 cooperates with the middle cover body 200 to form the material inlet 11a, and the outer diameter of the first segment 110 gradually increases from the material inlet 11a to the material outlet 11b. At this time, the upper size of the discharge structure is small, which is convenient for docking with external equipment. At the same time, the structure of the first segment 110 allows the insulation materials such as ball sand to be dispersed in the process of falling into the insulation box, so that the insulation materials can be evenly distributed.

[0031] Optionally, the first branch body 210 is arranged in parallel with the first section split body 110, so that the distance between the first branch body 210 and the first section split body 110 remains stable, which can prevent the insulation materials such as ball sand from clogging.

[0032] In one embodiment, if Figure 1 As shown, the middle cover body 200 includes a first branch body 210 and a second branch body 220 connected to each other, a material inlet 11a is formed between one end of the first branch body 210 away from the second branch body 220 and one end of the first segment body 110 away from the second segment body 120, and a material outlet 11b vertically arranged downward is formed between one end of the second branch body 220 away from the first branch body 210 and one end of the second segment body 120 away from the first segment body 110. The heat-insulating materials such as ball sand first pass through the channel between the first segment body 110 and the first branch body 210, and then pass through the channel between the second branch body 220 and the second segment body 120, and enter the heat-insulating box in a vertical downward posture, which can prevent the heat-insulating materials such as ball sand from entering the heat-insulating box in an inclined posture and colliding with the inner wall of the heat-insulating box, and will not affect the uniform distribution of the heat-insulating materials such as ball sand in the heat-insulating box. At the same time, less collision can also reduce the generation of dust.

[0033] Optionally, the shape of the outer cover body 300 matches the shape of the middle cover body 200, so that the suction port of the dust suction channel is flush or approximately flush with the material outlet 11b, ensuring that the dust suction channel can extract the dust generated in the insulation box.

[0034] In one embodiment, if Figure 1 As shown, the first functional channel 11 is provided with an inter-hood guide support 400, and the two sides of the inter-hood guide support 400 are respectively in contact with the first segment body 110 and the first branch body 210, and the number of the inter-hood guide support 400 is multiple, and the inter-hood guide support 400 is arranged at intervals along the circumference of the inner layer cover body 100. The inter-hood guide support 400 can be used to support the first segment body 110 and the first branch body 210, to ensure the spacing between the first segment body 110 and the first branch body 210, so that the insulation materials such as ball sand can smoothly pass through the discharge channel into the insulation box, and at the same time, the inter-hood guide support 400 can prevent the first segment body 110 and the first branch body 210 from wrinkling, so that the insulation materials such as ball sand will not stay at the wrinkles, which can reduce the loss of insulation materials and reduce the cleaning work of the above-mentioned discharge structure.

[0035] Optionally, two sides of the inter-cover flow guide support 400 are respectively connected to the inner cover body 100 and the outer cover body 300 .

[0036] In one embodiment, if Figure 1 As shown, the above-mentioned discharge system also includes a guide member. The inner cover body 100, the middle cover body 200 and the outer cover body 300 are all made of soft materials. A plurality of sliding parts are provided on the side of the second section split body 120 away from the inner cover body 100. The sliding parts are slidably matched with the guide member. The guide member is a retractable structure. The guide member is connected to the first section split body 110. There are multiple guide members, and the guide members are arranged at circumferential intervals along the second section split body 120. Since the inner cover body 100, the middle cover body 200 and the outer cover body 300 are all made of soft materials, when the above-mentioned discharge structure is placed on the ground, the inner cover body 100, the middle cover body 200 and the outer cover body 300 will be folded. However, since a sliding part is provided on the second section split 120, the sliding part can slide along the guide member, and the guide member is a retractable structure. Therefore, through the extension and retraction of the guide member and the sliding part sliding along the guide member, the shape of each folding can be similar. At the same time, when it is flattened again under the action of gravity, the unfolding is more complete and balanced, which can reduce the generation of wrinkles and will not retain insulation materials such as ball sand.

[0037] Optionally, a protective layer is provided on the side opposite to the first section body 110 and the first branch body 210. The protective layer is made of wear-resistant material, which can reduce the wear of the middle cover body 200 and the inner cover body during the transportation of insulation materials such as ball sand.

[0038] Optionally, a frame is provided on the second section body 120 along the circumferential direction, and the sliding part is provided on the frame. There are multiple frames and they are arranged at intervals along the axial direction of the second section body 120. At this time, the second section body 120 from top to bottom moves more synchronously during the folding and flattening process, and the generation of wrinkles can also be reduced.

[0039] In one embodiment, the guide member is a telescopic rod, the sliding part is a guide wheel arranged on the middle cover body 200, the sliding part and the middle cover body 200 are arranged at intervals, the guide member is arranged between the sliding part and the middle cover body 200, and an arc groove matching the guide member is arranged on the outer circumference of the guide member. At this time, the guide member cooperates with the sliding part to form a guide rope structure, so that the middle cover body 200 can be fully flattened to reduce the appearance of wrinkles.

[0040] In one embodiment, if Figure 1 As shown, the above-mentioned discharge structure also includes a material discharge piece 510 and a dust extraction piece 520. The material discharge piece 510 is connected to one end of the middle cover body 200 away from the material outlet 11b, and the material discharge piece 510 surrounds a material discharge port connected to the first functional channel 11. The dust extraction piece 520 is connected to one end of the outer cover body 300 away from the material outlet 11b. The dust extraction piece 520 is sleeved outside the material discharge piece 510 and is spaced from the material discharge piece 510. At this time, the material discharge piece 510 can conveniently deliver heat-insulating materials such as ball sand into the discharge channel, and the dust extraction piece 520 can be conveniently connected to an external exhaust device for dust extraction.

[0041] Optionally, one end of the inner cover body 100 close to the discharge piece 510 is a conical structure, which facilitates the entry of insulation materials such as ball sand and then being dispersed by the conical structure, so that the insulation materials are evenly dispersed throughout the annular discharge channel and evenly distributed in the insulation box.

[0042] In one embodiment, if Figure 1 As shown, a support member is provided between the middle cover body 200 and the outer cover body 300, so that the middle cover body 200 and the outer cover body 300 are spaced apart. At this time, the support member can ensure the smoothness of the dust collection channel and reduce the generation of dust.

[0043] One embodiment discloses a material distribution system, including an insulation box and a material discharge structure as in any of the above embodiments, wherein an opening is provided on the insulation box, and the outer cover body 300 extends into the opening; or the end of the outer cover body 300 is placed on the insulation box, so that the first functional channel 11 and the second functional channel 12 are connected to the opening.

[0044] The above-mentioned distribution system can cover at least the casting port of the mold with the inner cover body 100 after the mold is placed in the insulation box, and then the ball sand can be transported into the insulation box through the first functional channel 11 or the second functional channel 12. Since the casting port of the mold is covered at this time, the ball sand will not fall into the mold and will not affect the subsequent casting. Since the middle cover body 200 is sleeved on the outside of the inner cover body 100 and the outer cover body 300 is sleeved on the outside of the middle cover body 200, the first functional channel 11 and the second functional channel 12 are both arranged around the mold. Therefore, the ball sand can be evenly distributed around the mold when entering the insulation box, and there will be no uneven distribution of the ball sand, which has a better insulation effect on the mold. When one of the first functional channel 11 and the second functional channel 12 is used as a discharge channel for discharging the ball sand, the other can be used as a dust suction channel to extract the dust generated in the process of the ball sand entering the insulation box, which can greatly reduce the cleaning work and reduce dust pollution.
