Description

Technical Field

[0001] The invention relates to the field of feeding devices, in particular to a material feeding device for a zinc oxide enrichment production line for ceramic glaze. Background Art

[0002] Zinc oxide in ceramic glaze can reduce the high temperature viscosity of the glaze, increase the fluidity of the glaze, improve the gloss of the glaze, and also enhance the mechanical strength and chemical stability of the glaze, thus improving the performance and appearance of the ceramic. On the zinc oxide enrichment production line, zinc oxide materials are prone to form hard lumps during transportation due to factors such as environmental humidity, storage pressure and material weight. The crushing before transportation cannot cover the large pieces of material produced subsequently. If the material is crushed to a uniform particle size in advance, the small pieces of material are easy to agglomerate again due to vibration and friction during transportation, affecting the crushing effect. If the crushing link is placed at a later stage and mixed into the crushing chamber, it will not only significantly increase the energy consumption of the equipment, but also increase the difficulty of crushing due to differences in the compressive strength of the materials, significantly reduce the crushing efficiency, and ultimately cause problems such as uneven feeding of the roasting furnace.

[0010] Preferably, the space inside the air reservoir close to the sliding plate is larger than the space inside the air reservoir far from the sliding plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1.

At the same time, the crusher is placed at the back, and the crushed material enters the roasting furnace directly after a short distance of transportation, which is also helpful to avoid the re-agglomeration of materials caused by long-term transportation, affecting the uniformity of the materials and further affecting the final product effect.

[0014] 2. The present invention increases the internal space of the first conveying bin by opening an expansion slot on the side wall of the first conveying bin. When the material moves to the position of the expansion slot, the increased space can promote the downward movement of small particle materials in the upper layer, which is beneficial to improving the screening effect. Furthermore, by obliquely guiding the material, the material has a tendency to move toward the inner walls on both sides of the expansion slot, so that the loosening effect is gradually increased, and it can also ensure that the feeding position of the expansion slot is always full of material, slowing down the entry speed of the material, thereby avoiding a large amount of material from the outside of the expansion slot rushing in, causing blockage in the expansion slot.

[0015] 3. When the two sliding plates move away from each other, the surface of the airbag cover contacts the friction protrusion to form a friction surface, which increases the sliding friction of the material, thereby extending the residence time of the material in the expansion slot. When the two sliding plates approach each other for discharging, the airbag cover separates from the friction protrusion, thereby reducing the friction of the material, thereby ensuring that the material can slide out of the expansion slot smoothly and avoiding material blockage in the expansion slot.

DETAILED DESCRIPTION

[0025] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0026] like Figures 1 to 8 The material feeding device of a zinc oxide enrichment production line for ceramic glaze shown in the figure comprises a mounting frame 1, on which a first conveying bin 2 is arranged, one end of the first conveying bin 2 is rotatably connected to the mounting frame 1, a first electric push rod 3 is arranged between the other end of the first conveying bin 2 and the mounting frame 1, the fixed end of the first electric push rod 3 is fixedly connected to the mounting frame 1, a discharge trough 4 is opened on the bottom surface of the first conveying bin 2, a screen 5 is fixed on the inner wall of the discharge trough 4, a crusher 6 is arranged at the end of the first conveying bin 2, and the crusher 6 is fixed on the surface of the mounting frame 1, a second conveying bin 7 is arranged below the first conveying bin 2, a movable rod 8 is fixed on the bottom surface of the second conveying bin 7, the movable rod 8 is inserted into the mounting frame 1, a pressure sensor 9 is sleeved on the outer side of the movable rod 8, and a first spring 10 is fixed between the pressure sensor 9 and the second conveying bin 7.

[0027] Specifically, during the transportation process, zinc oxide materials are easily compacted and lumped due to factors such as environmental humidity, storage pressure and material deadweight. The crushing before transportation cannot cover the large pieces of materials generated subsequently. If they are crushed to a uniform particle size in advance, small pieces of materials are easily reaggregated during transportation due to vibration and friction, affecting the crushing effect. If the crushing link is placed at a later stage and mixed into the crushing chamber, not only will the energy consumption of the equipment be significantly increased, but the crushing difficulty will also increase sharply due to the difference in the compressive strength of the materials, significantly reducing the crushing efficiency, and ultimately causing problems such as uneven feeding of the roasting furnace. The present invention can solve the above problems. The specific working method is as follows: the first electric push rod 3 is pushed upward to make one end of the first conveying bin 2 tilt up, and the inclination degree of the first conveying bin 2 can be adjusted. When conveying materials, the materials are conveyed to the inclined first conveying bin 2 through the external feeding equipment, and the materials slide along the first conveying bin 2 to the feeding port of the crusher 6. During the sliding process, small particles of materials can fall from the screen 5 to the second conveying bin 7 located below, and continue to slide along the second conveying bin 7, while large particles of materials enter the interior of the crusher 6, and after being crushed into small particles, they also fall to the first conveying bin 7. Above the second conveying bin 7, the end of the second conveying bin 7 is connected to the feed port of the roasting furnace, and the small-particle material can be directly conveyed into the roasting furnace through the second conveying bin 7. In this process, by screening out the small-particle material in the material in advance, it is helpful to reduce the crushing pressure of the crusher 6 and ensure the crushing efficiency. At the same time, the crusher 6 is placed at the back, and the crushed material enters the roasting furnace directly after a short distance of transportation, which is also helpful to avoid the re-agglomeration of the material caused by long-term transportation, affecting the uniformity of the material, and then affecting the effect of the final product. Since the sizes of the initial materials are different, when there are more small particles in the initial materials, in order to ensure the amount of material entering the roasting furnace, it is necessary to reduce the power of the crusher 6 and reduce the discharge of the crusher 6. When there are fewer small particles in the initial materials, it is necessary to increase the power of the crusher 6 and increase the discharge of the crusher 6. The present invention sets a pressure sensor 9 at the bottom of the second conveying bin 7, and detects the pressure on the second conveying bin 7 through the pressure sensor 9, so as to determine the amount of small particles, thereby automatically adjusting the power of the crusher 6 to ensure the consistency of the feeding amount.

[0028] As a further implementation scheme of the present invention, two expansion slots 11 are opened on the side wall of the first conveying bin 2, and a sliding plate 12 is slidably connected in each expansion slot 11. A pushing component is arranged on the outer wall of the first conveying bin 2, and the pushing component is used to push and pull the sliding plate 12 to move.

[0029] Specifically, the first conveying bin 2 can be set with a depth in the bin according to actual needs. For the first conveying bin 2 with a deeper depth, during the conveying process, some small-particle materials are located on the upper layer of large-particle materials. Due to the short conveying path, it is difficult for the small-particle materials to quickly move downward through the screen 5. In the process of passing through the screen 5, leakage may occur. In order to solve the above problem, the present invention opens an expansion slot 11 on the side wall of the first conveying bin 2 to increase the internal space of the first conveying bin 2. When the material moves to the position of the expansion slot 11, the enlarged space can promote the downward movement of the small-particle materials in the upper layer, which is beneficial to improve the screening effect. However, due to the expansion slot 11, the expansion slot 11 is not large enough to move the small-particle materials in the upper layer downward, which is beneficial to improve the screening effect. A small outlet will affect the smooth discharge of materials. Therefore, the present invention sets a slidable sliding plate 12 in the expansion slot 11. When discharging materials, the sliding plate 12 is pushed by the pushing assembly to gather the materials, so that the materials on both sides of the outlet of the expansion slot 11 can quickly gather at the outlet position, thereby ensuring that the materials can be discharged smoothly, and the sliding plate 12 is pushed back and forth to move the sliding plate 12 back and forth in the expansion slot 11, so that the materials are loosened and gathered again, and the arrangement and contact state between the particles are constantly changed, thereby promoting the falling of small particles in the upper layer and separating from large particles, thereby reducing the crushing pressure of the crusher 6 and ensuring the uniformity of the particle size of the conveyed material.

[0030] As a further embodiment of the present invention, a first connecting rod 13 and a second connecting rod 14 are fixed at both ends of the sliding plate 12, and positioning blocks 15 are connected to the surfaces of the first connecting rod 13 and the second connecting rod 14, and guide rods 16 are hinged on the opposite positioning blocks 15.

[0031] Specifically, in the process of the two sliding plates 12 moving away from each other to increase the loose space, if the loosening is performed automatically by the material, the loosening efficiency is low. In order to solve the above problem, the present invention sets a guide rod 16 between the two sliding plates 12, and the guide rod 16 is located at the bottom of the material. Small particles of material can pass through the gap between the guide rods 16 and contact the screen 5, and large particles of material are received by the guide rods 16 and slide on the surface of the guide rods 16. When the two sliding plates 12 move, the guide rods 16 can be driven to move synchronously through the first connecting rod 13 and the second connecting rod 14, thereby driving the large particles above the guide rods 16 to move, and causing the material to move to both sides of the loose space, which is beneficial to improve the dispersion efficiency of the material, further promote the falling of small particles of material in the upper layer, and further ensure the uniformity of the particle size of the conveyed material.

[0032] As a further implementation scheme of the present invention, the first connecting rod 13 includes a fixed rod 17 and a movable cylinder 18, the fixed rod 17 is fixed on the surface of the sliding plate 12, the movable cylinder 18 is slidably sleeved on the outer side of the fixed rod 17, a second spring 19 is fixed between the inner wall of the movable cylinder 18 and the end of the fixed rod 17, the positioning block 15 is fixed on the outer wall of the movable cylinder 18, a limiting groove 20 is opened on the surface of the movable cylinder 18, a limiting block 21 is inserted in the limiting groove 20, and the limiting block 21 is fixed on the inner wall of the expansion slot 11.

[0033] Specifically, when the two sliding plates 12 move away from each other, the fixed rod 17 can be driven to move, and the fixed rod 17 drives the movable cylinder 18 to move through the second spring 19. During the short-distance movement of the movable cylinder 18, the limit block 21 and the limit groove 20 are relatively displaced, so that the limit block 21 moves from one end of the limit groove 20 to the other end of the limit groove 20, restricting the movable cylinder 18 from continuing to move, and indirectly restricting one end of the guide rod 16 from continuing to move. By first moving the end of the guide rod 16 located at the feeding position for a distance and then stopping the movement, it is beneficial to increase the distance between the two guide rods 16 located in the middle, thereby ensuring the loosening effect of the material in the middle. As the sliding plate 12 continues to move, the second connecting rod 14 can drive the other end of the guide rod 16 to continue to move. Continue to move, because the guide rod 16 is rotatably connected to the positioning block 15, it can be rotated and tilted. It should be noted that the guide rod 16 can adopt a telescopic rod to ensure the smooth tilting action. This embodiment guides the material obliquely by tilting the guide rod 16. Under the guiding action, the material has a tendency to move toward the inner walls on both sides of the expansion slot 11. On the one hand, the separation space is increased to ensure that the upper small particle material can fall smoothly. On the other hand, the oblique guidance can make the material gradually move from the feeding position to both sides, so that the loosening effect is gradually increased, and it can also ensure that the feeding position of the expansion slot 11 is always full of materials, slowing down the entry speed of the materials, thereby avoiding a large amount of material on the outside of the expansion slot 11 from pouring in, causing blockage in the expansion slot 11.

[0034] As a further embodiment of the present invention, the guide rod 16 includes a fixed column 22 and a sleeve 23, the sleeve 23 is sleeved on the outside of the fixed column 22, the ends of the fixed column 22 and the sleeve 23 are hinged to the corresponding positioning block 15, the outer walls of the fixed column 22 and the sleeve 23 are jointly sleeved with an airbag cover 24, and a plurality of friction protrusions 25 are fixed on the surface of the sleeve 23.

[0035] Specifically, after the material enters, the longer the residence time in the expansion slot 11, the better the separation effect. In order to extend the residence time of the material in the expansion slot 11, the present invention sets an airbag cover 24 on the outer side of the guide rod 16. When the two sliding plates 12 move away from each other, the guide rod 16 extends. At this time, the airbag cover 24 is pulled, and the internal space increases, so that it can be close to the sleeve 23, so that the surface of the airbag cover 24 contacts the friction protrusion 25 to form a friction surface, thereby increasing the sliding friction of the material, thereby extending the residence time of the material in the expansion slot 11. When the two sliding plates 12 approach each other for discharge, the guide rod 16 contracts, thereby reducing the internal space of the airbag cover 24. Under the action of air pressure, the airbag cover 24 is separated from the friction protrusion 25, thereby reducing the friction of the material, thereby ensuring that the material can slide out of the expansion slot 11 smoothly, avoiding material blockage in the expansion slot 11.

[0036] As a further implementation scheme of the present invention, a strip groove 26 is provided on the outer wall of the second connecting rod 14, and a plurality of slide grooves 27 are provided on the inner wall of the strip groove 26. The positioning block 15 at the corresponding position is slidably connected inside the slide groove 27. A third spring 28 is fixed between one end of the positioning block 15 and the slide groove 27, and a push tube 29 is fixed between the other end of the positioning block 15 and the slide groove 27. An air cylinder 30 is fixed on the inner wall of the strip groove 26, and a conduit 31 is fixedly connected between the air cylinder 30 and the push tube 29. A piston 32 is inserted into the interior of the air cylinder 30, and a push rod 33 is fixed on the side of the piston 32 away from the air cylinder 30. A blocking block 34 is set and fixed to the strip groove 26, and the blocking block 34 is fixed on the inner wall of the expansion slot 11.

[0037] Specifically, when the two sliding plates 12 move away from each other, the second connecting rod 14 drives the push tube 29 and the positioning block 15 to move synchronously, and drives the end of the guide rod 16 to move through the positioning block 15 until the push rod 33 contacts the blocking block 34. Under the blocking action of the blocking block 34, the push rod 33 drives the piston 32 to move into the gas cylinder 30, and squeezes the gas in the gas cylinder 30 into the push tube 29, so that the push tube 29 is deformed and elongated, and pushes the positioning block 15 to move, so that the guide rod 16 at this position has a different inclination angle from other guide rods 16, so that the guiding space between adjacent guide rods 16 becomes larger as it is closer to the rear end, providing more room for movement of the material, promoting the loosening effect, and reducing material jamming.

[0038] As a further embodiment of the present invention, the space inside the gas cylinder 30 close to the sliding plate 12 is larger than the space inside the gas cylinder 30 far from the sliding plate 12 .

[0039] Specifically, since there are multiple guide rods 16, by setting the space in the air cylinder 30, it can be ensured that the guide rod 16 closer to the sliding plate 12 can be pushed a farther distance, thereby ensuring that each guide space can achieve a larger effect the closer to the rear end. It should be noted that there is a gap between the air cylinder 30 and the inner wall of the expansion slot 11, and the gap is larger on the side closer to the sliding plate 12. The blocking blocks 34 corresponding to the air cylinder 30 are fixed on the inner wall of the expansion slot 11 in sequence, and the length of the blocking blocks 34 becomes longer and longer. In the process of the air cylinder 30 moving to the position of the blocking block 34, the blocking block 34 at the front end can pass through the gap to avoid interference with the air cylinder 30 at the front end, until the blocking block 34 encounters the corresponding air cylinder 30, the blocking function is realized, thereby ensuring that the blocking block 34 only blocks the air cylinder 30 that is adapted to it.

[0040] As a further implementation scheme of the present invention, the pushing assembly includes a second electric push rod 35, which is fixed on the outer wall of the first conveying bin 2. The movable end of the second electric push rod 35 passes through the outer wall of the first conveying bin 2 and is fixed with a pushing plate 36. A plurality of fourth springs 37 are fixed between the pushing plate 36 and the sliding plate 12.

[0041] Specifically, in the process of the two sliding plates 12 approaching each other, if rigid pushing is always performed, since the material is between the two sliding plates 12, under the extrusion effect, if there is too much material, it may be stuck and affect the normal operation of the equipment. In order to solve the above problem, the present invention arranges a pushing plate 36 on the back of the two sliding plates 12, and the pushing plate 36 is elastically connected to the sliding plates 12, so that when the two sliding plates 12 approach each other to squeeze the material, it is elastic squeezing, which is beneficial to avoid the occurrence of jamming and ensure the normal operation of the equipment.

[0042] As a further embodiment of the present invention, an extension rod 38 is fixed to one side of the sliding plate 12 close to the pushing plate 36 . The extension rod 38 penetrates the pushing plate 36 and is fixed to a limiting plate 39 after extending out.

[0043] Specifically, in the process of the second electric push rod 35 pulling the sliding plate 12 backward, the sliding plate 12 pulls the pushing plate 36 to move through the limiting plate 39 and the extension rod 38, so that during the pulling process, the pulling force is rigid and the pushing force is elastic. The rigid pulling force can ensure that the sliding plate 12 can stably pull the guide rod 16 and adjust the loose state of the material.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
