Description

Technical Field

[0001] The utility model relates to the field of kaolin production, in particular to a feeding device for kaolin production. Background Art

[0002] Kaolin is a general term for clay or ore mainly composed of kaolinite group minerals. Kaolin has good dispersibility, adhesiveness, electrical insulation, ion exchangeability and relatively high refractoriness, and has good plasticity. Therefore, kaolin is widely used in ceramics, refractory materials, rubber, papermaking, paint, cement, petroleum, chemical industry, cosmetics and other aspects.

[0003] During the production process of kaolin, it generally needs to be calcined. For some kaolin products, calcination treatment can improve their whiteness, hardness and chemical stability. Before calcination, it is generally pulverized and ground to form a powdery or granular structure. However, kaolin has viscosity, and the internal temperature distribution of agglomerated kaolin during calcination may be uneven, which may affect the calcination effect. Based on this, the applicant proposes a feeding device for kaolin production, which is used to stir the kaolin before feeding it into the calciner to prevent agglomeration. Summary of the Invention

[0004] To solve the technical problem of agglomeration of kaolin before calcination feeding, the utility model provides a feeding device for kaolin production.

[0005] The utility model is realized by the following technical solutions: a feeding device for kaolin production, including a feeding cylinder, the top of the feeding cylinder is provided with a feeding port, and the inside of the feeding cylinder is provided with:

[0006] A driving shaft, which is rotationally connected to the feeding cylinder;

[0007] An auxiliary rotating cylinder, which is sleeved outside the driving shaft, is rotationally connected between the auxiliary rotating cylinder and the feeding cylinder, and at the same time, the auxiliary rotating cylinder and the driving shaft are connected by bevel gears;

[0008] A soil crushing mechanism, and one end of the driving shaft and the auxiliary rotating cylinder located inside the feeding cylinder are both connected with a soil crushing mechanism;

[0009] A wire mesh plate, and a pull-out wire mesh plate is connected to one side of the feeding cylinder.

[0010] Through the above technical solutions, when the driving shaft is driven to rotate, the driving shaft will drive the auxiliary rotating cylinder to rotate together through bevel gears. The lower ends of the driving shaft and the auxiliary rotating cylinder are both connected with a soil crushing mechanism. During rotation, the soil crushing mechanism breaks and stirs the kaolin to prevent agglomeration. The crushed kaolin is more likely to fall from the wire mesh plate and enter the calciner for calcination. It can avoid incomplete calcination caused by agglomeration of kaolin.

[0011] As a further improvement of the above solution, an installation frame is fixedly connected to the top of the feeding cylinder. One end of the driving shaft extends out of the feeding cylinder and the installation frame, and the end is connected with a pulley. A motor is fixedly installed on one side of the installation frame. A fixed cylinder is also fixedly connected to the feeding cylinder. The auxiliary rotating cylinder and the fixed cylinder are rotatably connected through a bearing.

[0012] Through the above technical solution, the installation frame is used to install the driving shaft and the motor. The driving shaft and the installation frame are rotatably connected. The fixed cylinder is used to install the auxiliary rotating cylinder. Among them, the fixed cylinder and the feeding cylinder are integrally fixedly connected and rotatably connected with the auxiliary rotating cylinder.

[0013] As a further improvement of the above solution, three bevel gears are provided. One bevel gear is fixedly connected to the driving shaft, another bevel gear is fixedly connected to the auxiliary rotating cylinder, and the third bevel gear is rotatably installed on the installation frame, and the third bevel gear is meshed and connected with the bevel gears on the driving shaft and the auxiliary rotating cylinder respectively.

[0014] Through the above technical solution, the combination of the three bevel gears enables the driving shaft to drive the meshed bevel gear to drive the auxiliary rotating cylinder to rotate in the reverse direction when the motor drives the driving shaft to rotate.

[0015] As a further improvement of the above solution, the soil crushing mechanism includes mounting plates. There are two mounting plates, namely the first plate and the second plate. Among them, the first plate is fixedly connected to the end of the driving shaft, and the second plate is fixedly connected to the outside of the auxiliary rotating cylinder.

[0016] As a further improvement of the above solution, the soil crushing mechanism further includes stirring rods. Stirring rods are fixedly connected to the lower ends of the first plate and the second plate. Crushing blades are fixedly connected to the stirring rods, and a pushing plate is fixedly connected to the bottom of the stirring rods.

[0017] Through the above technical solution, soil crushing mechanisms are connected below both the first plate and the second plate. Since the driving shaft and the auxiliary rotating cylinder rotate in opposite directions, it is necessary to control the installation position of the soil crushing mechanism to prevent mutual influence.

[0018] As a further improvement of the above solution, an installation opening is further provided on one side of the feeding cylinder. A side guide plate is fixedly connected to the outside of the installation opening. A positioning strip is fixedly connected to the side guide plate. A connecting plate is fixedly connected to one side of the wire mesh plate. A sealing edge is fixedly connected to the connecting plate.

[0019] Through the above technical solution, the installation opening facilitates the wire mesh plate to move in and out of the feeding cylinder from the side. The side guide plate and the positioning strip facilitate the positioning and installation of the wire mesh plate. The connecting plate is for facilitating the control of the wire mesh plate, and the sealing edge contacts the outer wall of the feeding cylinder after the wire mesh plate enters the feeding cylinder to form a seal.

[0020] As a further improvement of the above solution, fixing holes are also formed on the side of the connecting plate. At the same time, a fixing block is fixedly connected to the outside of the side guide plate. A cavity is formed inside the fixing block, and a locking rod is arranged inside the cavity. Both ends of the locking rod extend out of the fixing block, and a spring is sleeved outside the locking rod located inside the cavity.

[0021] Through the above technical solution, after the wire mesh plate (connecting plate) is installed in place, the positions of the fixing holes on the connecting plate correspond to the positions of the locking rods. Under the action of the spring, one side of the locking rod is inserted into the fixing holes, so that the connecting plate and the side guide plate can be fixed, that is, the wire mesh plate is fixed in the feeding cylinder.

[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] When the driving shaft and the auxiliary rotating cylinder of the present utility model rotate, the stirring rod and the crushing blade can break up the agglomerated kaolin. At the same time, the inclined push plate and the metal wires in the wire mesh plate can cut the agglomerated kaolin, preventing the situation that the uneven heating caused by the agglomeration of kaolin affects the calcination effect, ensuring the calcination and the quality of the final product. At the same time, the wire mesh plate adopts a detachable pull-out design, which is convenient for replacement. Description of the Drawings

[0032] Next, in combination with the accompanying drawings and the detailed implementation manner, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0033] Please refer to Figures 1 - 7 , a feeding device for kaolin production in this embodiment includes a feeding cylinder 1, and a feed inlet 2 is opened at the top of the feeding cylinder 1. The kaolin to be calcined enters the feeding cylinder 1 through the feed inlet 2, and then enters the calcination furnace through the feeding cylinder 1 for calcination.

[0034] First, a fixed cylinder 7 is fixedly connected to the top of the feeding cylinder 1, and an auxiliary rotating cylinder 8 is rotatably installed inside the fixed cylinder 7 through a bearing ring. That is, the auxiliary rotating cylinder 8 can only rotate and cannot move up and down. In addition, a driving shaft 3 is also provided inside the feeding cylinder 1, and the driving shaft 3 penetrates through the auxiliary rotating cylinder 8 as a whole. At the same time, in order to install the driving shaft 3 and drive the driving shaft 3 to rotate, a mounting frame 4 is fixedly connected to the top of the feeding cylinder 1. The upper end of the driving shaft 3 extends out of the mounting frame 4 and is rotatably connected to the mounting frame 4 through a plain bearing. A motor 6 is fixedly installed on one side of the mounting frame 4, and pulleys 5 are installed on the motor 6 shaft and the driving shaft 3, and the two pulleys 5 are connected by a belt. Therefore, through the cooperation of the motor 6 and the pulleys 5, the driving shaft 3 can be driven to rotate.

[0035] In order to drive the auxiliary rotating cylinder 8 to rotate together. Therefore, bevel gears 9 are provided. Specifically, a total of three bevel gears 9 are provided. The first bevel gear 9 is fixedly connected to the driving shaft 3, the second bevel gear 9 is fixedly connected to the auxiliary rotating cylinder 8, and the third bevel gear 9 is rotatably installed on the inner side wall of the mounting frame 4, and the third bevel gear 9 meshes with the first and second bevel gears 9 respectively. Due to the above description, both the driving shaft 3 and the auxiliary rotating cylinder 8 can only rotate and cannot move up and down. When the driving shaft 3 rotates, through the cooperation of the three bevel gears 9, the auxiliary rotating cylinder 8 will be driven to rotate together, and the driving shaft 3 and the auxiliary rotating cylinder 8 rotate in opposite directions.

[0036] The lower ends of the driving shaft 3 and the auxiliary rotating cylinder 8 are both located inside the feeding cylinder 1. A mounting plate 10 is fixedly connected to the bottom of the driving shaft 3, and a mounting plate 10 is also fixedly connected to the outer side of the bottom of the auxiliary rotating cylinder 8. Since the driving shaft 3 and the auxiliary rotating cylinder 8 rotate in opposite directions, in order to prevent collision, the mounting plate 10 located below the driving shaft 3 is shorter and is defined as the first plate 101; the mounting plate 10 located below the auxiliary rotating cylinder 8 is longer and is defined as the second plate 102.

[0037] A soil crushing mechanism 11 is connected below the mounting plate 10 (including the first plate 101 and the second plate 102). During rotation, it can stir the kaolin inside the feeding cylinder 1 to prevent it from caking. This avoids uneven internal temperature distribution caused by caking of kaolin, which affects the calcination effect.

[0038] Specifically, the soil crushing mechanism 11 includes stirring rods 12, which are first fixedly connected to the lower end surface of the mounting plate 10. A crushing blade 13 with a cutting edge at one end is fixedly connected to the stirring rod. In addition, the stirring rods 12 are grouped in fours, and a push plate 14 is fixedly connected to the lower end of each group of stirring rods 12, and the push plate 14 is inclinedly installed.

[0039] In addition, a wire mesh plate 18 is arranged inside the feeding cylinder 1 and below the soil crushing mechanism 11. The wire mesh plate 18 is a grid-like structure woven by metal wires in the middle. When the kaolin enters the feeding cylinder 1 from the feeding port 2, it falls onto the wire mesh plate 18. Since the kaolin generally undergoes grinding and crushing treatment before calcination, the un-caked kaolin can directly fall through the wire mesh plate 18 and enter the calcination furnace. When there is caking of kaolin, first, the driving shaft 3 and the auxiliary rotating cylinder 8 rotate. When the stirring rod 12 drives the crushing blade 13 to rotate, the sharp cutting edge part can break some of the caked kaolin. In addition, since the push plate 14 is inclinedly installed, when it rotates, the force exerted on the contacted kaolin can be decomposed into a horizontal thrust and a downward pressure. On the one hand, it pushes the kaolin to move, and at the same time, it exerts a downward pressure on the kaolin, and cooperates with the cutting action of the metal wires to decompose the kaolin. Therefore, large pieces of kaolin can be prevented from entering the calcination furnace.

[0040] Due to the frictional effect between the kaolin and the metal wires, the metal wires are prone to breakage after a long use time, which affects the feeding process. Therefore, in order to facilitate the disassembly, installation and replacement of the wire mounting plate 10, an installation opening 15 is provided on one side of the feeding cylinder 1, and a side guide plate 16 is arranged outside the installation opening 15, and the side guide plate 16 is fixedly connected to the feeding cylinder 1. In addition, positioning strips 17 are fixedly connected to the side guide plate 16 and the inner side wall of the feeding cylinder 1.

[0041] In addition, for the convenience of installation, a connecting plate 19 is fixedly connected to one side of the wire mesh plate 18, and a sealing edge 20 is fixedly connected to the connecting plate 19. Therefore, during installation, the wire mesh plate 18 and the connecting plate 19 are placed on the positioning strip 17, and the positioning strip 17 supports the wire mesh plate 18 and the connecting plate 19 from below. Then, directly push the wire mesh plate 18 to move it into the feeding cylinder 1 through the installation opening 15. At this time, the side guide plate 16 and the positioning strip 17 play a role in positioning and guiding during installation, and the positioning strip 17 also provides a supporting function. After installation, the sealing edge 20 on the connecting plate 19 contacts and fits with the outer side wall of the feeding cylinder 1 to form a seal to prevent kaolin from overflowing from the gap of the installation opening 15.

[0042] In addition, to fix the connecting plate 19 and the wire mesh plate 18, fixing holes 21 are provided on the side of the connecting plate 19. In addition, a fixing block 22 is fixedly connected to the outer side wall of the side guide plate 16. A cavity is provided inside the fixing block 22, and a locking rod 23 is arranged inside the cavity, and both ends of the locking rod 23 extend out of the fixing block 22. A pull ring is connected to the end of the locking rod 23 away from the side guide plate 16 to facilitate pulling the locking rod 23 to move. A spring 24 is sleeved on the outer side of the locking rod 23 located inside the fixing block 22. Under the action of the spring 24, the locking rod 23 is pushed to move, and one end of it enters the fixing hole 21. The side guide plate 16 and the connecting plate 19 are fixed together, thereby preventing the connecting plate 19 and the wire mesh plate 18 from moving and sliding out of the feeding cylinder 1. On the contrary, when it is necessary to remove the connecting plate 19 and the wire mesh plate 18, pull the pull ring to control the movement of the locking rod 23 to move it out of the fixing hole 21. At this time, the spring 24 is compressed. After the locking rod 23 moves out of the fixing hole 21, the connecting plate 19 and the wire mesh plate 18 can be directly taken out.

[0043] The implementation process and principle of a feeding device for kaolin production in the embodiment of the present application are as follows:

[0044] (1); Install the wire mesh plate 18, pull the locking rod 23 to move to avoid blocking. Move the connecting plate 19 and the wire mesh plate 18 along the side guide plate 16 and the positioning strip 17 so that the wire mesh plate 18 completely enters the installation opening 15. At this time, the wire mesh plate 18 is located directly below the stirring rod 12 and the pushing plate 14. And the sealing plate seals the installation opening 15 on the cylinder to prevent kaolin from overflowing from the installation opening 15.

[0045] Release the locking rod 23. Under the action of the spring 24, one end of the locking rod 23 is inserted into the fixing hole 21 on the side of the connecting plate 19 to fix the connecting plate 19 and the side guide plate 16 together to prevent the connecting plate 19 and the wire mesh plate 18 from slipping.

[0046] (2); During use, kaolin enters the feeding cylinder 1 from the feeding port 2 and falls onto the wire mesh plate 18. At this time, the unagglomerated kaolin can directly fall through the gaps of the wire mesh plate 18 and enter the calciner.

[0047] Meanwhile, the motor 6 and the pulley 5 cooperate to drive the rotation of the main shaft 3. Through the cooperation of three bevel gears 9, the auxiliary rotating cylinder 8 is driven to rotate, and the rotation directions of the main shaft 3 and the auxiliary rotating cylinder 8 are opposite. When the main shaft 3 and the auxiliary rotating cylinder 8 rotate, the soil crushing mechanism 11 is driven to rotate together through the mounting plate 10. The stirring rod 12 plays a role in stirring the kaolin. Cooperating with the crushing blade 13 with a cutting edge on one side, the agglomerated kaolin can be broken up. In addition, since the push plate 14 is inclinedly installed, when it rotates, it can apply a downward pressure to the contacting kaolin. Cooperating with the wire, the agglomerated kaolin is cut into small pieces, so as to avoid uneven internal heat absorption caused by too large volume after the kaolin agglomerates, which affects the final calcination effect and product quality.

[0048] (3): Since there is friction between the kaolin and the wire during feeding, the wire on the wire mesh plate 18 needs to be replaced regularly. At this time, the locking rod 23 is pulled so that one end of the locking rod 23 disengages from the connecting plate 19. At this time, the connecting plate 19 and the wire mesh plate 18 can be taken out of the feeding cylinder 1. The updated wire is convenient for subsequent use.

[0049] The above embodiments are only the preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
