Description

Technical Field

[0001] This application relates to the field of cement batching technology, and more specifically, to a fly ash proportioning device for a cement batching station. Background Technology

[0002] Fly ash is a fine solid particulate matter in the flue gas ash produced by fuel combustion, such as the fine ash collected from flue gas in coal-fired power plants. Fly ash mainly contains silicon dioxide, alumina, and iron oxide, and has been widely used in cement production and the manufacture of various lightweight building materials. Fly ash is used in the cement processing batching stage, and a proportioning device is usually used to proportion the fly ash. For example, Chinese patent CN202421770992.1 discloses a fly ash proportioning device for a cement batching station. The technical solution disclosed in the patent includes: a proportioning barrel, a sealing cover on one end of the outer surface of the proportioning barrel, a feed inlet and a stirring motor on one end of the outer surface of the sealing cover, the feed inlet being located on one side of the stirring motor, and a discharge valve pipe and a fixed support on the outer surface of the other end of the proportioning barrel, the fixed support being located around the discharge valve pipe. The fly ash proportioning device for cement batching plants described in this utility model has an inlet that facilitates filling with fly ash into the proportioning bucket during use. The central pipe in the inlet can vibrate under the drive of a vibrating motor and shake through a connecting spring, thereby causing the hopper to shake. The discharge inclined plate and the distribution bar inside the hopper will shake accordingly, and the distribution bar can disperse the fly ash in the hopper, thus preventing the fly ash from clumping.

[0003] However, this existing technology has certain limitations in its use. The mechanical shaking of the feeding inclined plate and the distributing bar can only disperse part of the fly ash. For fly ash that has formed large or dense clumps, the dispersion ability is limited, and the overall anti-caking performance still needs to be further improved. Summary of the Invention

[0004] The purpose of this application is to provide a fly ash proportioning device for cement batching plants, which can solve the technical problem that existing fly ash proportioning devices for cement batching plants have limited dispersion ability for fly ash that has formed large or dense lumps, and the overall anti-caking performance still needs to be further improved.

[0005] This application provides a fly ash proportioning device for a cement batching plant, including a proportioning bucket. The top of the proportioning bucket is connected to a first feed pipe and a second feed pipe, and the bottom of the proportioning bucket is connected to a discharge pipe. A dispersing component is installed inside the first feed pipe.

[0006] The dispersing assembly includes a dispersing plate and a cylinder. The dispersing plate is inclinedly disposed inside the first feed pipe, and the cylinder is fixedly disposed on the first feed pipe. The piston rod of the cylinder is connected to the dispersing plate and drives the dispersing plate to reciprocate.

[0007] Preferably, the end of the dispersing plate away from the cylinder is fixedly provided with a plurality of conical teeth.

[0008] Preferably, a baffle is fixedly provided at the upper end of the dispersing plate, and the baffle slides against the inner wall of the first feed pipe.

[0009] Preferably, a sleeve is fixedly provided at one end of the dispersing plate near the cylinder, and a sleeve is fixedly provided inside the first feed pipe, with the sleeve slidably sleeved inside the sleeve.

[0010] Preferably, there are two dispersing components, which are arranged sequentially from top to bottom inside the first feed pipe.

[0011] Preferably, the mixing tank is provided with a stirring assembly, which includes a motor, a rotating shaft and a plurality of stirring rods. The rotating shaft is rotatably mounted in the mixing tank via bearings. The motor is fixedly mounted on the mixing tank and the output shaft of the motor is connected to the rotating shaft. The stirring rods are fixedly mounted on the rotating shaft.

[0012] Preferably, a connecting rod is fixedly mounted on the rotating shaft, and a dispersing plate is fixedly mounted on the connecting rod, the dispersing plate corresponding to the bottom of the first feed pipe and the bottom of the second feed pipe.

[0013] Preferably, a feed hopper is fixedly provided at the top of both the first feed pipe and the top of the second feed pipe.

[0014] The beneficial effects of this utility model are:

[0015] This utility model provides a fly ash proportioning device for cement batching plants. In use, fly ash is fed into the first feed pipe and falls onto an inclined dispersing plate. A cylinder is activated, causing the dispersing plate to reciprocate. The plate periodically impacts the inner wall of the first feed pipe, breaking up and crushing any clumps of fly ash. The fly ash then continues to fall into the proportioning tank, where it is mixed with other materials and discharged through the discharge pipe. This device, by using the dispersing plate to push the fly ash against the inner wall of the first feed pipe, has a strong ability to break up and crush clumps of fly ash, effectively improving the treatment of clumped fly ash and preventing the clumps from affecting the accuracy of the proportioning and the quality of the subsequent cement.

[0030] It should be noted that all electrical components appearing in this application are connected to an external main controller and mains power. The main controller can be a conventional known device such as a computer for control. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as bolts, rivets and welding that are mature in the prior art. Furthermore, the machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. These are prior art known to those skilled in the art and will not be described in detail here.

[0031] like Figure 1 and 2 As shown, this application embodiment provides a fly ash proportioning device for a cement batching station, including a proportioning bucket 1. The top of the proportioning bucket 1 is connected to a first feed pipe 11 and a second feed pipe 12, and the bottom of the proportioning bucket 1 is connected to a discharge pipe 13. A dispersing component 2 is provided inside the first feed pipe 11.

[0032] The dispersing assembly 2 includes a dispersing plate 21 and a cylinder 22. The dispersing plate 21 is inclinedly disposed inside the first feed pipe 11, and the cylinder 22 is fixedly disposed on the first feed pipe 11. The piston rod of the cylinder 22 is connected to the dispersing plate 21 and drives the dispersing plate 21 to move back and forth.

[0033] When in use, fly ash is fed into the first feed pipe 11. The fly ash will fall onto the inclined dispersing plate 21. The cylinder 22 is turned on to drive the dispersing plate 21 to reciprocate. The dispersing plate 21 will periodically hit the inner wall of the first feed pipe 11, breaking up and crushing the clumps of fly ash. Then the fly ash continues to fall into the mixing tank 1. After being mixed with other materials, it is discharged from the discharge pipe 13.

[0034] The device uses the dispersing plate 21 to drive the fly ash to collide with the inner wall of the first feed pipe 11, which has a strong ability to disperse and break up clumped and hardened fly ash, effectively improving the treatment effect of clumped fly ash and effectively preventing fly ash from affecting the accuracy of the mix proportion and the quality of subsequent cement due to clumping.

[0035] like Figure 1 and 2 As shown in this embodiment, a plurality of conical teeth 23 are fixedly provided at the end of the dispersing plate 21 away from the cylinder 22; the conical teeth 23 can more effectively pierce and tear larger lumps, break the agglomerated fly ash into finer particles, and achieve a more thorough dispersion effect.

[0036] like Figure 1 and 2 As shown, in this embodiment, a baffle 24 is fixedly provided at the upper end of the dispersing plate 21. The baffle 24 slides against the inner wall of the first feed pipe 11. When the cylinder 22 drives the dispersing plate 21 to move, the baffle 24 moves with the dispersing plate 21 and always keeps in contact with the inner wall of the first feed pipe 11. After the fly ash falls onto the baffle 24, it will continue to fall onto the dispersing plate 21 along the baffle 24, so that all the fly ash must pass through the working surface of the dispersing plate 21, ensuring that all the fly ash can be processed by the dispersing component 2 without any blind spots. Moreover, it prevents the fly ash from falling onto the bottom surface of the dispersing plate 21, avoiding the accumulation of fly ash and causing the dispersing plate 21 to jam.

[0037] like Figure 1 and 2As shown, in this embodiment, a sleeve rod 25 is fixedly provided at one end of the dispersing plate 21 near the cylinder 22, and a sleeve 14 is fixedly provided inside the first feed pipe 11. The sleeve rod 25 is slidably sleeved inside the sleeve 14. When the cylinder 22 drives the dispersing plate 21 to move, the sleeve rod 25 slides inside the sleeve 14. The cooperation between the sleeve rod 25 and the sleeve 14 provides precise linear guidance for the reciprocating motion of the dispersing plate 21, ensuring its motion trajectory is stable, avoiding deflection or jamming, making each impact precise and effective, and enhancing the overall structural rigidity and stability of the dispersing assembly 2.

[0038] like Figure 1 and 2 As shown, in this embodiment, two dispersing components 2 are provided, and the two dispersing components 2 are arranged sequentially from top to bottom inside the first feed pipe 11. After the fly ash enters from the top of the first feed pipe 11, it is first initially dispersed by the upper dispersing component 2, and then continues to fall, and is dispersed again by the lower dispersing component 2. The sequential arrangement of the two dispersing components 2 realizes multiple dispersing treatments of fly ash, which can more thoroughly break up fly ash clumps, further improve the dispersion effect of fly ash, ensure that the fly ash entering the proportioning tank 1 has uniform quality, and provide a stronger guarantee for accurate batching.

[0039] like Figure 1 and 2 As shown, in this embodiment, a stirring assembly 3 is provided inside the mixing tank 1. The stirring assembly 3 includes a motor 31, a rotating shaft 32 and multiple stirring rods 33. The rotating shaft 32 is rotatably mounted inside the mixing tank 1 via bearings. The motor 31 is fixedly mounted on the mixing tank 1, and the output shaft of the motor 31 is connected to the rotating shaft 32. The stirring rods 33 are fixedly mounted on the rotating shaft 32.

[0040] When in use, the motor 31 is turned on to drive the rotating shaft 32 to rotate, which in turn causes the stirring rod 33 to make a circular motion in the mixing tank 1, mixing the fly ash and other materials entering the mixing tank 1. The setting of the stirring component 3 can make the fly ash and other materials entering the mixing tank 1 fully mixed, ensuring that the proportion of various materials is uniform and improving the quality and consistency of cement batching.

[0041] like Figure 1 and 3 As shown, in this embodiment, a connecting rod 34 is fixedly installed on the rotating shaft 32, and a dispersing plate 35 is fixedly installed on the connecting rod 34. The dispersing plate 35 corresponds to the bottom of the first feed pipe 11 and the bottom of the second feed pipe 12.

[0042] When in use, when the rotating shaft 32 rotates, it drives the connecting rod 34 and the dispersing plate 35 to rotate together. The dispersing plate 35 will periodically sweep across the area below the outlet of the first feed pipe 11 and the second feed pipe 12, and will beat the material falling from the bottom of the first feed pipe 11 and the second feed pipe 12. The dispersing plate 35 can further disperse the material falling from the feed pipe, while promoting the mixing of different materials, making the material entering the mixing tank 1 more uniform, improving the mixing effect and the quality of the ingredients.

[0043] like Figure 1 and 2 As shown in this embodiment, a feeding hopper 15 is fixedly provided at the top of the first feeding pipe 11 and the top of the second feeding pipe 12. The feeding hopper 15 facilitates the feeding of materials, expands the effective area of ​​the feeding port, reduces the possibility of material spillage, improves the efficiency and accuracy of feeding, and also makes the operation of the entire device more convenient and safe.

[0044] Working principle: When the fly ash proportioning device for cement batching plant provided in this application is in use, fly ash is fed into the first feed pipe 11. The fly ash will fall onto the inclined dispersing plate 21. The cylinder 22 is turned on to drive the dispersing plate 21 to reciprocate. The dispersing plate 21 will periodically hit the inner wall of the first feed pipe 11, breaking up and crushing the clumps of fly ash. Then the fly ash continues to fall into the proportioning tank 1. The motor 31 is turned on to drive the rotating shaft 32 to rotate. When the rotating shaft 32 rotates, it drives the connecting rod 34 and the dispersing plate 35 to rotate together. The dispersing plate 35 will periodically sweep across the area below the outlet of the first feed pipe 11 and the second feed pipe 12, and will beat the material falling from the bottom of the first feed pipe 11 and the second feed pipe 12. At the same time, the stirring rod 33 will make a circular motion in the proportioning tank 1 to stir and mix the fly ash and other materials entering the proportioning tank 1. After the mixing and proportioning are completed, the fly ash will be discharged from the discharge pipe 13.

[0045] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
