Technical Field

[0001] In the fields of waste treatment, waste gas purification, sludge treatment, etc., the production process often involves the feeding of powdery and granular materials such as activated carbon and lime. At the initial stage of feeding, it is necessary to perform a bag-breaking operation on the packaging ton bags of the materials. In the prior art, on automated and semi-automated production lines, bag-breaking equipment is used to break the ton bags and then feed the materials. For example, the patent with the publication number: CN117682191A discloses a bag-breaking device. It can adjust the cutting bag-breaking operation trajectory and bag-breaking method according to the material form of the ton bag.

[0002] However, in actual applications, it is found that when the material is fed through the feeding port of the feeding bin in the form of a ton bag, and the bag-breaking mechanism pierces the ton bag and the material is instantaneously fed into the feeding bin, it will cause the material to be compacted in the bin, thus affecting the further feeding efficiency. Summary of the Invention

[0003] In order to solve the problem in the prior art that the instantaneous feeding of materials into the feeding bin will cause the materials to be compacted in the bin and affect the feeding efficiency, the utility model provides an anti-arching feeding bin, which can reduce the probability of the materials being compacted and caked when fed into the feeding bin, and improve the fluidity of the materials during the feeding process.

[0004] The structure of the utility model is as follows: an anti-arching feeding bin, which comprises: a feeding bin body, a lifting and conveying mechanism, and a bag-breaking mechanism.

[0021] Figure 4 is Figure 1 Schematic enlarged view of part A in Specific implementation manner

[0022] As Figures 1 to 4 shown, the present application includes a hopper bin with arch breaking function, which includes: a main body 1 of the feeding bin, a bag slapping mechanism 2, a net plate structure 3, a bag breaking mechanism 4, an arch breaking mechanism 7, and a lifting and conveying mechanism (not marked in the figure). Among them, the lifting and conveying mechanism is arranged above the feeding port 11; the lifting and conveying mechanism can be realized based on the feeding mechanism capable of realizing the lifting function in the prior art.

[0023] The top of the main body 1 of the feeding bin is provided with a feeding port 11, and the bottom is provided with a discharging port 12; the bag breaking mechanism 4 is arranged below the feeding port 11. The arch breaking mechanism 7 and the net plate structure 3 are arranged in the inner cavity of the main body 1 of the feeding bin; the net plate structure 3 is located below the bag breaking mechanism 4; the arch breaking mechanism 7 is arranged below the net plate structure 3.

[0024] In the present application, a cylinder type bag slapping mechanism is provided, and the bag slapping mechanism 2 is arranged at the feeding port 11; the bag slapping mechanism 2 includes: a slapping cylinder 21, a slapping plate 22, and a rotating shaft 23.

[0025] The bottom end of the slapping plate 22 is rotatably installed in the inner cavity of the main body 1 of the feeding bin based on the rotating shaft 23, and is located below the feeding port 11; the top end of the slapping plate 22 is connected to the output end of the slapping cylinder 21; the top end of the slapping plate 22 extends upward higher than the feeding port 11, and the length of the slapping plate 22 is greater than the height of the bag breaking mechanism 4. The slapping cylinder 21 is fixed on the main body 1 of the feeding bin outside the feeding port 11, and the stroke track of the output end of the cylinder is inclined towards the feeding port 11. At least two bag slapping mechanisms 2 are arranged and symmetrically installed based on the center of the feeding port 11.

[0026] When the ton bag falls from the feeding port 11 from top to bottom based on the lifting and conveying mechanism, the slapping cylinder 21 is started, driving the top end of the slapping plate 22 to slap towards the feeding port 11. The slapping cylinders 21 on both sides are started simultaneously, then the slapping plates 22 on both sides strike the ton bag simultaneously from both sides, dispersing the caked materials inside it; the top end of the slapping plate 22 extends upward higher than the feeding port 11, and the length of the slapping plate 22 is greater than the height of the bag breaking mechanism 4, ensuring that the slapping position of the bag slapping mechanism 2 on the ton bag is set above the bag breaking mechanism 4, and slapping is performed before the ton bag is punctured. After slapping, the ton bag is then punctured by the bag breaking mechanism 4, ensuring that the materials can fall evenly into the bin.

[0027] The arch breaking mechanism 7 includes: an arch breaking motor 71, an arch breaking shaft 72 and a paddle 73; the arch breaking shaft 72 is rotatably arranged horizontally in the inner cavity of the feeding bin body 1, and both ends of the arch breaking shaft 72 pass through the side wall of the feeding bin body 1; one end of the arch breaking shaft 72 is connected to the output end of the arch breaking motor 71; and the paddle 73 is installed on the arch breaking shaft 72.

[0028] In this application, in order to ensure that the ton bag can be unloaded smoothly, the feed port 11 is set as a rectangular port or a square port, and in order to be able to smoothly connect with the subsequent production and processing equipment, the discharge port 12 is set as a circular port, and the side length of the feed port 11 is greater than the diameter of the discharge port 12. Because the feed port 11 is large and the discharge port 12 is small, the arch breaking mechanism 7 is mainly installed in the middle and lower part of the silo where the material is easily blocked. The arch breaking motor 71 cooperates with the reducer to drive the arch breaking shaft 72 to operate in the inner cavity of the silo. The paddles 73 set on the arch breaking shaft 72 break up the material during rotation, so that the material cannot be compacted and blocked, and is discharged smoothly from the discharge port 12.

[0029] A dust collecting port 13 is also provided on the top of the feeding bin body 1 to ensure that the dust in the bin can be safely led out of the feeding bin, thereby reducing the probability of dust spilling out. Figure 2 In the embodiment of the present invention, a dust collector 6 for collecting dust is provided, and the dust collector 6 is provided above the dust collecting port 13, and the dust inlet of the dust collector 6 is connected to the dust collecting port 13. The dust collecting port 13 is provided to ensure that the dust generated during the internal material feeding process can be discharged smoothly and collected by the dust collector 6, thereby reducing dust overflow and reducing pollution.

[0030] The bag breaking mechanism 4 includes: a knife tip structure 41 and a blade 42; the blade 42 is arranged below the knife tip structure 41, and at least two blades 42 are arranged. The top of the blade 42 is connected to the bottom of the knife tip structure 41, and the bottoms are far away from each other and evenly arranged on the circumference with the knife tip projection as the center. The knife tip structure and the blade constitute a pyramid or cone structure; the knife tip structure 41 is arranged upward, and the blades 421 of adjacent blades 42 are far away from each other and face outward. The ton bag packaging from top to bottom is punctured by the knife tip structure 41. The blades 42 with blades facing outward have a narrow top distance and a wide bottom distance between each other. As the ton bag falls, the bevel of the ton bag can be gradually expanded to ensure that the material inside can fall smoothly. When the break on the ton bag reaches a certain degree, the ton bag can continue to be torn open based on the gravity of the internal material, so a set of bag breaking mechanisms 3 composed of a knife tip structure and a blade is set in the present application to realize the bag breaking function. The specific distance between the bottoms of multiple blades can be set according to the material shape of the ton bag. The material of the ton bag is relatively strong, so the conical bottom surface formed by the blades can be set larger. Figure 4In the embodiment, three blades 42 are provided. The three blades 42 form a regular triangular pyramid, and the cutting edge 421 of each blade 42 is located on three edges intersecting at the tip position. There are gaps between the bottoms of all the blades to ensure that the material can fall smoothly; it also prevents material accumulation that may cause equipment damage.

[0031] During specific installation, it is fixed in the inner cavity of the feeding bin body 1 through square steel 5 to form the steel structure of the mounting rack. The bag-breaking mechanism 4 is installed on the steel structure formed by the square steel 5. At the same time, a mesh plate structure 3 can also be installed below the bag-breaking mechanism 4 based on the same steel structure.

[0032] The mesh plate structure 3 is realized based on a wire mesh or a grille. The specific mesh size is adaptively set according to the properties of the material. Through the setting of the mesh plate structure 3, it is ensured that the material impacting and falling from top to bottom is buffered and segmented by the mesh plate structure 3, and at the same time, the impact force of the material on the underlying arch-breaking mechanism 7 is reduced.

[0033] After the ton bag is punctured by the bag-breaking mechanism 4, the internal material impacts the mesh plate structure 3 from top to bottom. If there are still agglomerated materials, the materials with less severe agglomeration will break when impacting the mesh plate structure 3, reducing the probability of large pieces of material entering the feeding bin. If there are overly severely agglomerated materials that cannot be broken, they will also be screened out by the mesh plate structure 3 to prevent them from entering the inner cavity of the feeding bin.

[0034] After using the technical solution of the present utility model, the arch-breaking mechanism, the bag-patting mechanism, and the bag-breaking bin are organically combined. By applying the arch-breaking mechanism and the bag-patting mechanism, blockage during feeding can be avoided. The technical solution of this application is mainly applied to bag-breaking and feeding pneumatic conveying systems such as: new energy negative electrode feeding systems, steel plant carbon powder feeding systems. The advantages of the arch-breaking type feeding bin of this application are simple structure, easy to implement, and simple operation.
