Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of chemical technology, and in particular to a material storage and retrieving system. Background Art
[0002] There are two main types of storage yards for bulk industrial materials such as coal, petroleum coke, and sulfur: circular yards and strip yards. The strip yard is rectangular in shape, and the feeding can be done by belt conveyors or bucket wheel stackers. The materials are piled into a long cone shape, and scraper reclaimers and bucket wheel reclaimers are used for reclaiming when leaving the warehouse, and then the materials are sent out of the yard by belt conveyors. Since strip yards have corners, their site utilization rate is lower than that of circular yards. Therefore, circular yards are more commonly used in storage in the chemical industry.
[0003] In the existing circular material yard, there are equipment and components such as cantilever stackers and scraper reclaimers. When stacking materials, the cantilever stacker is used to rotate around the support frame to stack materials into a cone-shaped material in the circular field. When retrieving materials, the scraper reclaimer is used to rotate around the support frame and scrape the materials into the hopper under the support frame, and then the materials are sent out of the circular material yard through the belt conveyor under the hopper. The circular material yard has many mechanical equipment and high equipment costs. The equipment itself will occupy a large area of the material yard, which will also reduce the material storage capacity of the material yard. At the same time, the large drop when stacking materials and the scraper reclaimer will also cause the granular sulfur to break and produce dust. Summary of the invention
[0004] The purpose of the present disclosure is to provide a material storage and retrieving system to improve the material storage capacity of a material field in the related art, while reducing the generation of dust and lowering the equipment cost.
[0005] In order to achieve the above object, the present disclosure provides a material storage and retrieving system, comprising:
[0006] A material yard, comprising side walls for standing on the ground, wherein the side walls are configured in a cylindrical shape to enclose a space for accommodating materials;
[0007] A transport channel, the transport channel is arranged in the material yard, the transport channel extends from the ground toward a direction away from the ground, the upper part of the transport channel is used to connect with the feeding equipment, and the lower part of the transport channel is used to connect with the inside of the material yard; and
[0008] The hopper is arranged on the ground, the inlet of the hopper is connected to the material field in an openable and closable manner, and the outlet of the hopper is arranged below the inlet of the hopper for connecting to a discharging device arranged on the ground.
[0009] Optionally, the transport channel comprises:
[0010] A support frame, the support frame is vertically extended and arranged at the center of the material yard, and the bottom of the support frame is connected to the ground; and
[0011] The slideway is connected to the support frame for supporting the slideway, wherein the entrance of the slideway is arranged at the upper part of the support frame, and the exit of the slideway is arranged at the lower part of the support frame.
[0012] Optionally, the slideway is spiral-shaped and is arranged around the outer side of the support frame.
[0013] Optionally, the cross-section of the slideway is an open structure.
[0014] Optionally, a first cleaning device is provided on the slide and moves along the slide to clean the slide.
[0015] Optionally, there are two first cleaning devices, which are respectively arranged on the surface of the slideway that carries the material and the surface that is away from the material.

[0027] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0028] In the present disclosure, unless otherwise stated, the directional words used, such as "upper", "lower", "top", and "bottom", are defined with respect to the actual use direction of the storage and retrieval system. Figure 1 In the drawing directions shown, "inside" and "outside" are defined with respect to the outlines of the corresponding components. The terms "first", "second", etc. are used for the purpose of distinguishing different components and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.
[0029] According to one embodiment of the present disclosure, Figure 1 and Figure 2 As shown, a material storage and retrieval system is provided, which may include a material yard 1, a transport channel 2 and a hopper 3. The material yard 1 may include a side wall 12 for standing on the ground 11, and the side wall 12 is configured in a cylindrical shape to enclose a space for accommodating materials. The transport channel 2 is arranged in the material yard 1, and the transport channel 2 extends from the ground 11 toward a direction away from the ground 11. The upper part of the transport channel 2 is used to connect with a feeding device 61, and the lower part of the transport channel 2 is used to connect with the interior of the material yard 1. The hopper 3 can be set in the ground 11, and the inlet of the hopper 3 can be connected to the material yard 1 in an openable and closable manner. The outlet of the hopper 3 is set below the inlet of the hopper 3, and is used to connect with a discharging device 62 set in the ground 11.
[0030] It should be noted that the stored material can be granular sulfur or bulk materials such as coal and petroleum coke, wherein the ground 11 here can also refer to the ground 11 of a certain thickness corresponding to the material yard 1 surrounded by the side wall 12, which is hollowed out and the side wall 12 and the bottom plate are arranged on the edge of the hollowed ground 11 to connect with the material yard 1 so as to enclose the hopper 3 in the material yard 1. It is also possible that the side wall 12 and the bottom plate are not arranged under the ground 11, and the hopper 3 is only dug in the ground 11. The present disclosure does not limit this.
[0031] Through the above technical solution, no mechanical equipment is required in the stacking process of the storage and reclaiming system, and the particles can be completely dependent on gravity to fall, which can effectively reduce dust generated by material crushing. The equipment of the storage and reclaiming system is simplified, which can reduce the occupied space in the material yard 1. Compared with the traditional material yard, the material yard 1 can store more materials under the same floor area and height. In addition, due to the simplified equipment, the stacking and reclaiming process of the storage and reclaiming system is simple, the equipment investment is reduced, and the cost can be effectively reduced.
[0032] In the technical solution disclosed in the present invention, the material field 1 can be circular, the diameter of the circle enclosed by the side wall 12 can range from 20m to 100m, and the height of the side wall 12 can range from 5m to 30m. Taking the diameter of the circle as 40m and the height of the side wall 12 as 12m as an example, the stacking height of the stored materials along the side wall 12 can reach 9m, which can reach 10,000 to 15,000 tons (occupying a space of about 15700m 3 ) can meet the storage needs of most conveying equipment corresponding to 200,000 to 500,000 tons of materials. Under the same side wall 12 height, the diameter of the traditional circular material yard must reach 50m-60m to achieve the same storage capacity. When the circle diameter is 60m, the storage capacity can reach 50,000 tons, which is equivalent to the storage capacity of the traditional circular material yard with a diameter of 80 meters. The area occupied under the same storage capacity is greatly reduced.
[0033] Furthermore, if Figure 1As shown, the transport channel 2 may include a support frame 21 and a slide 22, wherein the support frame 21 may extend vertically and be arranged at the center of the material yard 1, and the bottom of the support frame 21 is connected to the ground 11. The support frame 21 may be a cylinder or cone with a height of 22 meters, and its height may also be adjusted according to the specifications of the material yard 1, which is not limited in the present disclosure. The support frame 21 is connected to the slide 22 for supporting the slide 22, wherein the entrance of the slide 22 is arranged at the upper part of the support frame 21, and the exit of the slide 22 is arranged at the lower part of the support frame 21. The slide 22 may be located inside the support frame 21 or outside the support frame 21, which is also not limited in the present disclosure. The slide 22 may be vertical or stepped and arranged on one side of the support frame 21 to achieve the function of transporting materials. The slideway 22 may also be spiral and arranged around the outside of the support frame 21, thereby slowing down the falling speed of the material, reducing the possibility of material breakage and the height of dust stirred up when the material slides down and accumulates on the ground 11, which is not limited in the present disclosure.
[0034] Specifically, the cross-section of the slide 22 can be an open structure. Since dust is present when the material slides down, sparks may appear during the friction of the material falling down. Therefore, the dust of the material is prone to explosion in a confined space. Setting the slide 22 to an open structure can increase the safety of transportation and prevent safety accidents caused by explosions.
[0035] According to one embodiment of the present disclosure, Figure 2 As shown, the slide 22 may be provided with a first cleaning device 4 that moves along the slide 22, and is used to clean the slide 22. After the slide 22 has transported materials for many times, the materials may easily adhere to the slide 22 due to the adhesion of some loose materials and the agglomeration caused by the humidity of the air, making the slide 22 narrower, reducing the transport volume, and easily causing blockage. The first cleaning device 4 may be an electric sweeper, and the automatic start interval or automatic start time may be set on the slide 22 as needed, or a wireless remote control device may be added or connected to the operating table through a circuit, and cleaning of different times and intensities may be performed according to the instructions, and the present disclosure does not limit this.
[0036] Furthermore, if Figure 2As shown, the first cleaning device 4 can be provided in two numbers, and they are respectively provided on the surface of the slideway 22 that carries the materials and the surface that is away from the materials. When the materials are discharged from the slideway 22, a material pile 7 will be formed on the ground 11. When the material pile 7 is piled high, part of the slideway 22 will be gradually submerged in the material pile 7 from bottom to top. When part of the materials are taken out, the height of the material pile 7 will drop. At this time, part of the slideway 22 originally buried in the material pile 7 will be exposed, and the surface of this part of the slideway 22 away from the materials will also be stained with part of the materials. Therefore, the first cleaning device 4 is also provided on the surface of the slideway 22 away from the materials, so as to clean the slideway 22 in all directions, thereby preventing the materials from being wasted by adhesion.
[0037] According to an embodiment of the present disclosure, a charging device 5 may also be provided on the slide 22 for charging the first cleaning device 4. The charging device 5 is fixed at the entrance of the slide 22. When the first cleaning device 4 returns to the entrance of the slide 22 after cleaning, the first cleaning device 4 may be connected to the charging device 5, thereby charging the first cleaning device 4, so as to extend the battery life of the first cleaning device 4 and perform subsequent cleaning work. The charging device 5 may be a wireless charging device or a wired charging device, which is not limited in the present disclosure. When the charging device 5 is a wireless charging device, when the first cleaning device 4 returns to the entrance of the slide 22 and enters the identification area of the charging device 5, it can be automatically charged without additional operation. When the charging device 5 is a wired charging device, after the first cleaning device 4 returns to the entrance of the slide 22, the charging external parts of the two can be manually connected together for charging, or matching conductive grooves and protrusions may be provided on the first cleaning device 4 and the charging device 5. After the first cleaning device 4 moves to a predetermined position, the protrusion automatically snaps into the groove to charge the first cleaning device 4.
[0038] According to one embodiment of the present disclosure, Figure 1 As shown, the side wall 12 may be provided with a track 13 that surrounds the side wall 12, and the track 13 may be provided with a second cleaning device that moves along the track 13, which is used to clean the materials at the connection between the side wall 12 and the ground 11 to the top of the hopper 3, so that the materials in the dead angle area 8 formed at the connection between the side wall 12 and the ground 11 can be smoothly taken away, thereby improving the utilization rate of the material yard 1. In addition, for the dead angle area 8 formed by the accumulation of materials near the slide 22, a third cleaning device may also be provided at the exit of the slide 22, and the third cleaning device may clean the dead angle area 8 near the slide 22, and clean the materials therein to the top of the hopper 3, thereby improving the utilization rate of the material yard 1. A cleaning device that can move arbitrarily on the ground 11 surrounded by the side wall 12 may also be provided in the material yard 1, so that materials at any position in the material yard 1 may be cleaned to the top of the hopper 3 as needed, and the present disclosure does not limit this.
[0039] According to one embodiment of the present disclosure, Figure 1 As shown, the material yard 1 includes a roof 14, which can be arranged above the side wall 12 and connected to the side wall 12 to close the material yard 1 to prevent impurities such as rain, snow, and dust from mixing into the material and affecting the quality of the material.
[0040] According to one embodiment of the present disclosure, there are multiple hoppers 3, and they are distributed in a ring around the transport channel 2, so as to take materials from multiple directions, while minimizing the scope of the dead angle area 8 of the material yard 1 as much as possible, thereby improving the operating efficiency of the storage and material taking system. Generally speaking, in a material yard 1 with a commonly used circumferential diameter of 40m, 3-8 hoppers 3 can be set to meet production needs. The feeding device 61 and the discharging device 62 can be belt conveyors or tubular conveyors, and the number can be set as needed. The number of discharging devices 62 can correspond to the number of hoppers 3 one by one, or multiple hoppers 3 can share one discharging device 62, which is not limited by the present disclosure. In the case where the discharging device 62 is a belt conveyor, the hopper 3 can be set to 4, and evenly distributed along the circumference with the center of the transport channel 2 as the center of the circle, and the evenly distributed radius can be 10 meters. The number of discharging devices 62 can be 2, and every 2 hoppers 3 can share one discharging device 62.

Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0043] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
