Description

Technical Field

[0001] The utility model belongs to the technical field of bulk material transportation equipment, and particularly relates to an anti-spill material discharge channel and a discharge transportation device. Background Art

[0002] Existing block materials such as lime material discharge channel and discharge transport device such as Figure 1 As shown, the bottom discharge port 2 of the discharge channel is a straight discharge trough 1, and the discharge and transportation device also includes a chain conveyor 3 located in the lime kiln pit. Several transport buckets 4 on the chain conveyor 3 can move along the conveying direction of the chain conveyor 3 and can be located below the straight discharge trough 1, so that the high-temperature lime can fall from the straight discharge trough 1 into the corresponding empty transport bucket 4 directly below it. As the chain conveyor 3 advances, the previous transport bucket 4 loaded with lime moves forward, and the next empty transport bucket 4 advances to the bottom of the straight discharge trough 1 for corresponding discharge and loading. In this way, the discharge channel cooperates with each transport bucket 4 to carry out continuous discharge and sequential transportation. After reaching the designated position, the transport bucket 4 flips over with the operation of the chain conveyor 3 to unload and can be empty and re-connected. However, on-site observations revealed that a large amount of material leakage occurred in the area near the direct discharge chute 1 at the tail of the chain conveyor 3. The main reason is that when the finished limestone product falls directly from the cooler at a height of about 2 meters through the direct discharge chute 1 into the steel transport bucket 4 of the chain conveyor 3, the finished limestone product is affected by the acceleration of gravity and will generate a large impact force, causing the material to rebound after colliding with the transport bucket 4 of the chain conveyor 3 during material reception, posing a risk of damage to the chain conveyor 3. At the same time, the material is caused to be scattered and fall between the buckets to form leakage. The production operation area staff need to enter the environment to perform regular material cleaning operations, which is not only time-consuming and labor-intensive, but also the ambient temperature in this area is high and it is a limited space and relatively closed. Frequent entry of personnel into the operation brings inevitable operational risks such as heatstroke and suffocation. Therefore, improving the lime material discharge and transportation structure to prevent material spillage is of great significance to safe and environmentally friendly production.

[0003] The existing anti-spillage structures for material unloading and transportation are mostly to install baffles on the sides of the unloading trough and the transport bucket or to raise the walls of the transport bucket, but are limited by the installation space. For example, it is inconvenient to install baffles on the wall inside the transport bucket. Due to the limitation of continuous transportation and transportation space, the walls of the transport bucket cannot be raised or baffles cannot be installed. Lime will still leak out from between the buckets. Due to the high temperature limit of the delivered limestone finished product, conventional PVC, cloth curtains and other materials should not be set outside the unloading port of the unloading channel. There is a risk of burning. Or because the setting is not dense enough, the curtains may sweep the materials in the transport bucket and cause leakage. Therefore, the existing structure cannot solve the above-mentioned problem of hidden dangers in the current operation caused by material spillage. Utility Model Content

[0004] The present invention aims to solve at least one of the above-mentioned technical problems to a certain extent. The present invention provides a material discharge channel and a material discharge transportation device that can prevent spillage. The structure is simple, and the material discharge channel and the material discharge transportation device can effectively reduce the problem of spillage on site, which is conducive to improving the safety and environmental protection of the operation.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A material discharge channel for preventing spillage, the material discharge channel comprising at least one set of connected upper shells and lower shells, an upper channel being provided in the upper shell, an inclined channel and a curtain being provided in the lower shell, the inclined channel being arranged obliquely and connected to the upper channel, the curtain being located on the vertical section of the inclined channel, the top end of the curtain being connected to the upper shell or the lower shell, and the bottom end of the curtain being perpendicular to the bottom surface of the inclined channel.

[0007] In a preferred embodiment, the upper channel is vertically arranged, and the discharge port of the inclined channel is located on the lower side of the upper channel.

[0008] In a preferred embodiment, it includes a lower shell located at the bottom end of the material discharge channel, and the discharge port of the lower shell is arranged horizontally.

[0009] In a preferred embodiment, a wear-resistant plate is provided on the inner wall of the bottom of the lower shell and is located directly below the upper channel.

[0010] In a preferred embodiment, the barrier curtain comprises a plurality of chains arranged at intervals.

[0011] A spill-proof material unloading and transporting device comprises a conveyor and a material unloading channel as described above, wherein the conveyor is provided with a transport bucket, and the transport bucket can be moved below the discharge port of the material unloading channel.

[0012] In a preferred embodiment, the transport bucket comprises a plurality of transport buckets arranged adjacent to each other along the transport direction of the transport aircraft.

[0013] In a preferred embodiment, a guide plate inclined toward the inner side of the transport bucket is provided on one side of the transport bucket, and the guide plate extends to above the adjacent transport bucket.

[0014] In a preferred embodiment, the front wall and the rear wall of the transport bucket are both arranged to be inclined relative to the bottom, and the rear wall of the front transport bucket is close to the front wall of the rear transport bucket.

[0015] Compared with the prior art, the beneficial effects of the present invention are at least:

[0016] The material unloading channel is increased or the lower part of the upper shell is improved to a lower shell with an inclined channel and a curtain. After the material is discharged along the upper channel, the material's running trajectory can be changed by the inclined channel. After the impact and rebound activity between the material and the lower shell is over, the curtain can be used to further buffer the impact force of the material to reduce the kinetic energy of the material.

[0026] Example 1:

[0027] Aiming at the problem of hidden dangers in on-site operation caused by the spillage of bulk materials during unloading and transportation in the existing technology, such as Figure 2 and Figure 3 As shown, a preferred embodiment of the anti-spill material discharge channel of the utility model is shown, and the material discharge channel includes at least one set of connected upper shells 5 and lower shells 6, and an upper channel 501 is provided in the upper shell 5, and an inclined channel 601 and a curtain 7 are provided in the lower shell 6. The inclined channel 601 is inclined and connected to the upper channel 501, and the curtain 7 is located on the vertical section of the inclined channel 601. The top end of the curtain 7 is connected to the upper shell 5 or the lower shell 6, and the bottom end of the curtain 7 is perpendicular to the bottom surface of the inclined channel 601.

[0028] like Figure 2 As shown, after the material is discharged through the upper channel 501, it enters the inclined and connected inclined channel 601 and continues to discharge along the inclined channel 601. The inclined channel 601 can be used to forcibly change the falling trajectory of the material. After the material falls, it can fall on the inner bottom surface of the lower shell 6, directly collide and rebound with the inner wall of the lower shell 6, and at the same time, the rebounded material, such as the finished limestone product, can further hit the curtain 7 intercepted on the vertical section of the inclined channel 601, thereby effectively slowing down the impact force of the potential energy conversion when the material falls from a height. At the same time, since the curtain 7 is only fixed at the upper end and the lower end is not connected to the lower shell 6, the material can pass through the gap of the curtain 7 itself, the curtain 7 is lifted up after being impacted, and then the gap with the bottom surface of the inclined channel 601 is increased, and the material continues to be discharged to avoid blockage. Furthermore, by buffering the material, it is avoided that the transport bucket 4 below the material discharge channel is strongly impacted during the discharge process, thereby avoiding rebound, spillage, and leakage of the material.

[0029] In a preferred embodiment, the upper channel 501 is vertically arranged, and the discharge port 602 of the inclined channel 601 is located at the lower side of the upper channel 501, for example, Figure 2 As shown, materials such as limestone can be discharged vertically along the vertical upper channel 501 at a faster discharge speed, and the discharge port 602 of the inclined channel 601 is located on the lower side of the upper channel 501, that is, the bottom surface of the inclined channel 601 can cover the discharge section of the upper channel 501, fully buffering all materials falling from the upper channel 501. The inclination angle between the upper channel 501 and the inclined channel 601 can be set as needed according to factors such as installation space and discharge height.

[0030] In a preferred embodiment, the lower shell 6 is located at the bottom end of the material discharge channel, and the discharge port 602 of the lower shell 6 is arranged horizontally, for example, Figure 2 As shown, the lower shell 6 can be connected to the upper shell 5 through a flange 8 or welding, and the horizontal discharge port 602 of the lower shell 6 can also serve as the discharge port 2 of the material discharge channel. The structure is simple, which makes it more convenient to improve the structure of the existing material discharge channel and reduce the modification cost.

[0031] In a preferred embodiment, a wear-resistant plate 9 is provided on the inner wall of the bottom of the lower shell 6 and is located directly below the upper channel 501, for example, Figure 2 and Figure 3 As shown, the wear-resistant plate 9 can be multiple pieces, and a number of countersunk holes 901 are provided on the wear-resistant plate 9. The countersunk holes 901 are provided with a connection with the bottom plate 603 of the lower shell 6 to realize the installation of the wear-resistant plate 9. The wear-resistant plate 9 can be made of steel plates, high-temperature resistant composite plates and other materials to adapt to the discharge of block materials such as high-temperature limestone products, and the wear-resistant plate 9 is located directly below the upper channel 501, which can improve the deformation resistance and wear resistance of the lower shell 6 under the impact of materials, and improve the durability and life of the material discharge channel.

[0032] In a preferred embodiment, the curtain 7 includes a plurality of chains 701 arranged at intervals, for example, Figure 3 As shown, the chain 701 can be made of interlocking steel, the upper end of the chain 701 is welded to the top side of the lower shell 6, and the lower end of the chain 701 is hung close to the inner bottom surface of the lower shell 6. Compared with curtain pieces made of PVC and other materials, the chain 701 has better high temperature resistance, is more convenient for unloading high-temperature materials such as limestone products, and has better wear resistance and impact resistance, which is more convenient for blocking and buffering materials. At the same time, compared with flexible curtain 7 structures such as wire mesh, the gap between adjacent chains 701 is larger, more flexible, and more convenient for the passage of buffered materials, avoiding accumulation and blockage of the inclined channel 601. At the same time, the passage of materials through the gaps between adjacent chains 701 can also play a role in breaking up and preventing material agglomeration.

[0033] Example 2:

[0034] like Figure 4 As shown, it is a preferred embodiment of the anti-spill material unloading and transportation device of the present invention, the material unloading and transportation device includes a conveyor and a material unloading channel as described in Example 1, the conveyor is provided with a transport bucket 4, and the transport bucket 4 can be moved to the bottom of the discharge port 2 of the material unloading channel.

[0035] like Figure 4 As shown, during material unloading and transportation, when the material falls along the upper channel 501, the material trajectory is changed by the inclined channel 601, and the bottom surface of the lower shell 6 just below the upper channel 501 collides with the material. The material collides with the curtain 7 to buffer the potential energy, so that the material with a slowed unloading speed can fall from the unloading port 602 of the material unloading channel into the transport bucket 4 below, avoiding the rebound and spillage of high-speed material falling into the transport bucket 4, and then the transport bucket 4 loaded with material is driven forward by a conveyor, such as a chain conveyor 3, to realize the spillage and unloading transportation, which not only effectively reduces the risk of material impact injury, but also can effectively reduce leakage through practical observation, without the need for frequent cleaning by personnel, greatly reducing the labor intensity of personnel in the workshop, and the on-site 5S management has been greatly improved, which has also played a certain positive role in saving costs and effectively improving the safety and environmental protection benefits of the workshop site.

[0036] In a preferred embodiment, the transport bucket 4 includes a plurality of transport buckets 4 arranged adjacent to each other along the transport direction of the transporter, for example, Figure 4 As shown, multiple transport buckets 4 are installed on the chain plates of the chain plate conveyor 3, and can move forward with the chain plates of the chain plate conveyor 3 to continuously receive materials and transport them in sequence, thereby improving the efficiency of material unloading and transportation.

[0037] In a preferred embodiment, a guide plate 10 is provided on one side of the transport bucket 4 and is inclined toward the inner side of the transport bucket 4. The guide plate 10 extends to the upper side of the adjacent transport bucket 4. For example, Figure 4 As shown, the guide plate blocks the gap between adjacent transport buckets 4 in the vertical direction, which facilitates the guiding of materials when they are discharged from the material discharge channel to the corresponding transport bucket 4, and also facilitates the unloading and guiding of materials when the transport bucket 4 runs with the chain conveyor 3 to the front end and flips over, further reducing the risk of leakage.

[0038] In a preferred embodiment, the front wall and the rear wall of the transport bucket 4 are both inclined with respect to the bottom, and the rear wall of the previous transport bucket 4 is close to the front wall of the next transport bucket 4, for example, Figure 4 As shown, the guide plate 10 is inclined to the front wall of the corresponding transport bucket 4, so that the guide plate 10 can cover the gap between adjacent transport buckets 4. The inclined front wall and rear wall facilitate further stopping and buffering of the material, reduce the risk of rebound and spillage, and also facilitate guidance when the transport bucket 4 is unloading.

[0039] The series of detailed descriptions listed above are only specific descriptions of feasible embodiments of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent embodiments or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
