Description
Technical Field
[0001] The present application relates to the technical field of anti-pollution of bulk material silos, and in particular to a bulk material silo system for preventing contamination of bulk material piles. Background Art
[0002] The existing bulk storage system for transporting and storing fertilizer products generally includes a bulk storage and a belt conveyor. The bulk storage is used to store bulk materials. The belt conveyor includes a suspended belt and a distribution trolley. The suspended belt and the distribution trolley are arranged directly above the bulk storage and are used to transport bulk materials to the bulk storage to form a bulk pile. Fertilizer products have certain hygroscopic and caking characteristics. In order to prevent caking, anti-caking agents are added in the actual industrial production at home and abroad to prevent fertilizer caking. At present, anti-caking agents containing oily substances are commonly used. The finished product with the anti-caking agent containing oily substances is transported to the bulk storage by a belt conveyor, and the material is distributed by the suspended belt and the distribution trolley above the bulk storage. Because the finished product belt, roller and roller are affected by factors such as oily substances, production dust and belt wear, during the operation of the conveyor, there will be debris such as dandruff and oil stains scattered along the line below the belt in the products stored in the bulk storage, that is, in the bulk pile, which seriously affects the cleanliness of the product.
[0003] In order to solve this problem, in the prior art, on the one hand, scrapers are added to the belts in the non-bulk material warehouse distribution area to scrape and clean at fixed points to reduce the randomness of the above-mentioned debris spilling; on the other hand, manual inspections are adopted. When the above-mentioned debris is found to have spilled onto a large pile of products, manual inspections are performed in a timely manner to manually climb onto the large pile to pick out the above-mentioned debris.
[0004] However, the scraping and cleaning effect of the scraper itself is difficult to completely eliminate the debris at a fixed point. In addition, the belt itself is easy to wear, the oily substance has high viscosity, the roller and roller are greasy and vibrate and fall off, and the scattered debris is covered by the new cloth and is difficult to find. Therefore, the problem of debris contaminating the product cannot be completely solved. Compared with the same industry, there are similar situations. The measures generally taken to prevent the mixing of debris brought in by the conveyor belt are relatively similar. As a result, a lot of manpower and material resources are invested, but it is still difficult to prevent, which seriously affects the cleanliness of fertilizer products. Utility Model Content

[0033] The existing bulk storage system for transporting and storing fertilizer products generally includes a bulk storage and a belt conveyor. The bulk storage is used to store bulk materials. The belt conveyor includes a suspended belt and a distribution trolley. The suspended belt and the distribution trolley are arranged directly above the bulk storage and are used to transport bulk materials to the bulk storage. Fertilizer products have certain characteristics of hygroscopic agglomeration. In order to prevent agglomeration, anti-caking agents are added in the actual industrial production at home and abroad to prevent fertilizer agglomeration. At present, anti-caking agents containing oily substances are commonly used. The finished product with the anti-caking agent containing oily substances is transported to the bulk storage by a belt conveyor, and the material is distributed by the suspended belt and the distribution trolley above the bulk storage. Because the finished product belt, roller and roller are affected by factors such as oily substances, production dust and belt wear, during the operation of the conveyor, there will be debris such as dandruff and oil stains scattered along the belt below the belt in the products stored in the bulk storage, which seriously affects the cleanliness of the product.
[0034] In order to solve this problem, in the prior art, on the one hand, scrapers are added to the belts in the non-bulk material warehouse distribution area to scrape and clean at fixed points to reduce the randomness of the above-mentioned debris spilling; on the other hand, manual inspections are adopted. When the above-mentioned debris is found to have spilled onto a large pile of products, manual inspections are performed in a timely manner to manually climb onto the large pile to pick out the above-mentioned debris.
[0035] However, the scraping and cleaning effect of the scraper itself is difficult to completely eliminate the debris at a fixed point. In addition, the belt itself is easy to wear, the oily substance has high viscosity, the roller and roller are greasy and vibrate and fall off, and the scattered debris is covered by the new cloth and is difficult to find. Therefore, the problem of debris contaminating the product cannot be completely solved. Compared with the same industry, there are similar situations. The measures generally taken to prevent the mixing of debris brought in by the conveyor belt are relatively similar. As a result, a lot of manpower and material resources are invested, but it is still difficult to prevent, which seriously affects the cleanliness of fertilizer products.
[0036] In order to solve the above technical problems, the present application proposes a bulk material storage system that prevents contamination of bulk material piles, which can prevent dandruff, oil stains and other debris along the line below the suspended belt from being scattered into the products stored in the bulk material storage, thereby improving the cleanliness of the products.
[0037] like Figure 1 and Figure 2 As shown, a bulk material storage system for preventing contamination of bulk material piles includes a collecting trough 1, which is arranged directly below the suspended belt 9. The collecting trough 1 extends along the moving direction of the suspended belt 9. The length of the collecting trough 1 is greater than or equal to the length of the suspended belt 9 entering the bulk material warehouse, and the width of the collecting trough 1 is greater than the width of the suspended belt 9.
[0038] The collecting trough 1 is a trough-shaped structure for collecting the suspended belt 9. Specifically, the collecting trough 1 can be a through trough without baffles at both ends, or a semi-enclosed trough-shaped structure with baffles at both ends; it can be a chute with a bottom plate inclined toward one end; or it can be a trough-shaped structure with a bottom plate parallel to the suspended belt 9. As long as the collecting trough 1 can completely cover the space directly below the suspended belt 9, so that all the debris dropped from the suspended belt 9 falls into the collecting trough 1, the specific structure and type of the collecting trough 1 are not limited.
[0039] Specifically, Figure 1 As shown, the suspended belt 9 passes through the entire bulk material warehouse, and the collecting trough 1 can be arranged between two bulk material warehouse partition walls 12, so that all the debris falling from the suspended belt 9 above the bulk material warehouse can fall into the collecting trough 1. More specifically, the suspended belt 9 includes a return belt 91 and a material conveying belt 92, and the material conveying belt 92 is arranged on the top of the return belt 91 for conveying materials.
[0040] Compared with the prior art, the bulk material storage system provided by the present application is capable of preventing contamination of bulk material piles, by setting a collecting trough 1 directly below the suspended belt 9, and making the length of the collecting trough 1 greater than the length of the suspended belt 9 entering the bulk material storage, and the width of the collecting trough 1 greater than the width of the suspended belt 9, so that dandruff, grease and other debris along the line below the suspended belt 9 entering the bulk material storage can all fall into the collecting trough 1, thereby preventing debris from being scattered in the products stored in the bulk material storage, and at the same time reducing the workload of inspection personnel and improving the cleanliness of the products.
[0041] In some modified embodiments of the present application, the collecting tank 1 includes a collecting tank 1 bottom plate, two side plates and two baffles, the two baffles are fixedly connected to the first end and the second end of the collecting tank 1, respectively, the two side plates are arranged on both sides of the collecting tank 1, and the bottom plate is fixedly connected to the bottom of the two side plates and the two baffles.
[0042] Specifically, Figure 1 As shown, the collecting tank 1 can be composed of two right-angled trapezoidal aluminum alloy side plates, a rectangular aluminum alloy bottom plate and two rectangular aluminum alloy baffles, thereby forming a semi-closed collecting tank 1, which prevents debris from falling into the collecting tank 1 and then falling from both ends of the collecting tank 1, further preventing debris from being scattered in the products stored in the bulk warehouse, and further improving the cleanliness of the products.
[0043] like Figure 1 As shown, in some modified embodiments of the present application, the bottom plate is inclined from the first end of the collecting tank 1 to the lower part of the second end, and a collecting port 5 is provided at the bottom of the second end of the collecting tank 1. By providing the inclined bottom plate and the collecting port 5, it is convenient to collect the debris in the collecting tank 1.
[0044] The collecting port 5 is a receiving device arranged at the bottom outlet of the collecting tank 1. Specifically, the collecting port 5 can be a square hollow shell or a quadrangular cone-shaped hollow shell. As long as the collecting port 5 can receive the debris at the bottom outlet of the collecting tank 1, the specific structure of the collecting port 5 is not limited. More specifically, the bottom plate inclination angle can be set to an angle of not less than 30 degrees along the return direction of the suspended belt 9, so as to ensure that the debris in the collecting tank 1 can fall along the inclination direction of the bottom plate, and avoid the debris from accumulating in the collecting tank 1.
[0045] In some modified implementations of the present application, the bulk material storage system for preventing bulk material pile contamination also includes a compressed air purge device 3, which is disposed on a baffle at the first end of the collecting tank 1. The compressed air purge device 3 is a device that can spray air in a fixed direction; specifically, the compressed air purge device 3 can be a pipeline air purge device or a positive pressure purge device. As long as the compressed air purge device 3 can blow air in a fixed direction of the collecting tank 1 so that the debris in the collecting tank 1 rolls along the inclined bottom plate to the collecting port 5, the specific structure and type of the compressed air purge device 3 are not limited. By providing the compressed air purge device 3, the debris in the collecting tank 1 can be blown down to the collecting port 5 along the inclined direction of the bottom plate, further preventing the debris from accumulating in the collecting tank 1.
[0046] In some modified embodiments of the present application, the compressed air blowing device 3 includes a blowing nozzle 31 and an air supply system. The air supply system and the blowing nozzle 31 are connected through an air duct 32. The direction of the blowing nozzle 31 is the same as the inclination direction of the base plate.
[0047] The blowing nozzle 31 is an important accessory of the compressed air blowing device 3 for concentrating, guiding and controlling the direction of the air. Specifically, the blowing nozzle 31 can be a conical or cylindrical blowing nozzle 31, or a flat or diffuse blowing nozzle 31; more specifically, the cross section of the blowing nozzle 31 can be a shape similar to an obtuse triangle, forming a diffuse blowing nozzle 31 to increase the blowing range, further ensuring that the debris in the collection tank 1 can be blown down to the collection port 5 along the inclined direction of the bottom plate, and further avoiding the accumulation of debris in the collection tank 1.
[0048] Specifically, an electric ball valve 4 may be provided on the air duct, and the electric ball valve 4 may be connected to an electrical automatic control system to control the opening and closing of the blowing nozzle 31; the air supply system is a device for supplying air into the air duct; specifically, the air supply system may be a centrifugal fan, an axial flow fan, and a cross-flow fan. As long as the air supply system can supply air to the air duct and the blowing nozzle 31, there is no specific limitation on the structure and type of the air supply system.
[0049] In some modified implementations of the present application, the bulk material storage system for preventing bulk material pile contamination further includes a debris collection bucket 7, which is arranged directly below the collection port 5. The debris collection bucket 7 is a device for receiving debris; specifically, the debris collection bucket 7 can be a barrel structure or a square hollow shell structure with an upward opening. As long as the debris collection bucket 7 can receive the debris falling from the collection port 5, there is no specific limitation on the structure of the debris collection bucket 7. By arranging the debris collection bucket 7 directly below the collection port 5, the debris is collected to avoid environmental pollution.
[0050] In some modified embodiments of the present application, the bulk storage system for preventing bulk material pile pollution further includes a chute 6, which is arranged at the bottom of the collection port 5, and the opening of the chute 6 faces the debris collection bucket 7. The chute 6 is a pipe for connecting the collection port 5, so that the debris in the collection port 5 can enter the debris collection bucket 7 under the guidance of the chute 6, thereby preventing the debris from falling outside the debris collection bucket 7 and polluting the environment.
[0051] In some modified embodiments of the present application, the opening extends in a direction perpendicular to the side plate, and the length of the opening is equal to the width of the bottom plate; a collecting device is arranged between the outlet and the chute 6, and the collecting device is a hollow quadrangular pyramid structure, the bottom of the collecting device is connected to the chute 6, and the top of the collecting device is connected to the opening.
[0052] Specifically, the top surface (i.e., the surface where the top is located) and the bottom surface (i.e., the surface where the bottom is located) of the collecting device are two parallel surfaces, and the top surface of the collecting device is the surface with a larger area, whereas the bottom surface is the surface with a smaller area. The hollow tetrahedral pyramid structure is installed at the outlet at the end of the semi-enclosed collecting chute 1, and the shape of the tetrahedral pyramid top surface corresponds to the shape at the outlet of the collecting chute 1. The side with a larger area of the hollow tetrahedral pyramid structure is connected to the end baffle, bottom plate and two side plates of the semi-enclosed collecting chute 1. More specifically, the chute 6 is installed below the collecting port 5, connected to the collecting port 5, and fixed on the wall of the bulk material warehouse or the partition wall in the middle of the bulk material warehouse, and the outlet at the lower end of the chute 6 can be 500 mm from the ground.
[0053] The side length of the collecting opening 5 is consistent with the width of the bottom plate, so that the debris can flow out directly from the opening to prevent the debris from accumulating at the opening. The collecting opening 5 makes the opening and the chute 6 relatively smoothly connected, which not only ensures that the debris does not accumulate at the opening, but also plays a good guiding role for the debris, preventing the debris from falling outside the debris collection bucket 7.
[0054] In some modified embodiments of the present application, a suspended belt bracket 13 is further included, and a plurality of through holes 10 are provided on the suspended belt bracket 13, and the plurality of through holes 10 are connected to a plurality of hanging holes provided on the collection tank 1 through hooks 2; wherein the plurality of hanging holes are provided on the top of the side plate, and the plurality of hanging holes are evenly arranged along the extension direction of the collection tank 1, and the through holes 10 of the suspended belt bracket 13 correspond to the positions of the hanging holes on the side plate. Specifically, the suspended belt bracket 13 is a bracket provided at the bottom of the suspended belt 9 and supporting the suspended belt 9. By providing the plurality of hanging holes on the top of the side plate and making the plurality of hanging holes evenly arranged along the extension direction of the collection tank 1, it is possible to ensure that the collection tank 1 is subjected to uniform force, and improve the stability of the connection between the collection tank 1 and the suspended belt bracket 13.
[0055] In some modified embodiments of the present application, the width of the collecting trough 1 is smaller than the distance between the two discharge ports of the feeding trolley 8, so as to prevent the collecting trough 1 from affecting the feeding trolley's material distribution.
[0056] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
