Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a high-activity activation device for phosphorus slag. Background Technology

[0002] In the cement production process, phosphorus slag is a common industrial solid waste. Its resource utilization is an effective way to reduce production costs and achieve green and sustainable development. Phosphorus slag can be used as a cement admixture to partially replace expensive cement clinker. It can be ground together with clinker, gypsum, etc. to produce phosphorus slag silicate cement, which significantly reduces the dependence on clinker and reduces energy consumption and carbon emissions. The core value of phosphorus slag in its effective utilization lies in its potential high activity. This activity mainly comes from the large amount of amorphous calcium silicate contained in phosphorus slag, which can undergo a pozzolanic reaction in an alkaline environment to generate hydrated calcium silicate gel with cementing properties, thereby significantly improving the later strength and durability of cement and effectively reducing the heat of hydration.

[0003] The activation of phosphorus slag depends on two key prerequisites: first, sufficient physical crushing to destroy its structure and increase its specific surface area; second, uniform mixing with activator to provide the necessary chemical reaction environment. Traditional treatment methods usually use independent crushing and mixing equipment, which are complicated and discontinuous, have high energy consumption, are difficult to achieve industrial continuous production, and have limited processing capacity.

[0004] Therefore, a highly active activating device for phosphorus slag is proposed to solve the technical problem of the above-mentioned complicated process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a high-activity activation device for phosphorus slag, which has the advantage of continuous process and solves the problems of cumbersome and discontinuous process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-activity activation device for phosphorus slag, comprising a crushing chamber, a frame, and a mixing chamber connected sequentially from top to bottom, wherein a crushing mechanism is provided on the crushing chamber;

[0007] The crushing mechanism includes a first shaft disposed in the crushing chamber and a second shaft disposed in the crushing chamber. The first shaft and the second shaft are located on the same horizontal line. A plurality of crushing blades are disposed at equal intervals on the outer periphery of the first shaft and the second shaft. A drive assembly connected to the first shaft is disposed on the frame, and the drive assembly is used to drive the first shaft to perform circumferential rotation.

[0008] Furthermore, a drive module is provided on the frame, and a third shaft is provided on the outside of the output shaft of the drive module, with its other end penetrating and extending into the interior of the mixing chamber.

[0009] Furthermore, pulleys are fitted on the outer sides of both the third shaft and the first shaft, and the pulleys on the upper and lower sides are connected by belt drive.

[0010] Furthermore, gears are provided on the outer side of both the first shaft and the outer side of the second shaft, and the gears on the front and rear sides mesh with each other.

[0011] Furthermore, the mixing chamber is a cuboid with a hollow interior and a missing upper surface, used to add an activator into the mixing chamber. The lower part of the crushing chamber has a discharge port facing the mixing chamber.

[0012] Furthermore, a first stirring blade is provided on the outer periphery of the third shaft, and a second stirring blade is provided on the outer periphery of the third shaft.

[0013] Furthermore, both the first and second stirring blades are located inside the mixing chamber.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. This high-activity activation device for phosphorus slag connects the crushing chamber, frame and mixing chamber from top to bottom, and integrates the crushing mechanism and the stirring mechanism. It realizes the integrated and continuous operation of the entire process of phosphorus slag crushing, conveying and mixing. It effectively solves the problems of cumbersome procedures, high energy consumption and large footprint caused by the need for multiple equipment and multiple material transfers in traditional processes, and significantly improves the production efficiency and automation level of phosphorus slag pretreatment.

[0016] 2. This high-activity activation device for phosphorus slag utilizes meshing gears to synchronously drive two shafts equipped with crushing blades, forming a highly efficient roller-type shearing and crushing mode. This design not only ensures strong crushing force and high efficiency, effectively breaking down the glassy structure of the phosphorus slag and increasing its specific surface area, but also guarantees the synchronicity and stability of the dual-shaft rotation, resulting in more uniform particle size and laying a solid foundation for subsequent activation.

[0017] 3. This high-activity activation device for phosphorus slag simultaneously drives the crushing and stirring functions through a drive module. It has a compact structure and lower energy consumption. Specifically, the drive module connects the first shaft and the third shaft through a belt pulley drive, realizing the unified and efficient utilization of the power source and reducing the equipment manufacturing cost and operating energy consumption.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1 The high-activity activation device for phosphorus slag in this embodiment includes a crushing chamber 100, a frame 200 and a mixing chamber 300 connected in sequence from top to bottom. The crushing chamber 100 is provided with a crushing mechanism 400.

[0027] The crushing mechanism 400 includes a first shaft 401 disposed in the crushing chamber 100, a second shaft 402 disposed in the crushing chamber 100, the first shaft 401 and the second shaft 402 being located on the same horizontal line, a plurality of crushing blades 403 being equally spaced on the outer periphery of the first shaft 401 and the second shaft 402, and a drive assembly connected to the first shaft 401 being disposed on the frame 200, and the drive assembly being used to drive the first shaft 401 to perform circumferential rotational motion.

[0028] During application, the drive assembly is activated, driving the first shaft 401 to rotate circumferentially. The crushing blades 403 on the first shaft 401 rotate at high speed, forming a pair of highly efficient shearing and crushing pairs for the phosphorus slag in the crushing chamber 100. The crushed phosphorus slag is fed into the crushing chamber 100 from the top. The material is subjected to shearing, impact, and grinding by the high-speed relative rotation of the crushing blades 403 in the chamber, and is quickly broken into fine powder. The crushed phosphorus slag powder sinks naturally under the action of gravity and is discharged through the discharge port opened at the bottom of the crushing chamber 100. Since the discharge port faces the mixing chamber 300 below, the material can fall into the mixing chamber 300 seamlessly and continuously, completing the process from crushing to conveying. The phosphorus slag powder falling into the mixing chamber 300 is combined with the chemical activator added from the top of the mixing chamber 300, which prepares for the subsequent uniform mixing and activation reaction.

[0029] Example 2;

[0030] The basic content is the same as in Example 1, except that:

[0031] Please see Figure 2-3 In this embodiment, a drive module 404 is provided on the frame 200, and a third shaft 405 is provided on the outside of the output shaft of the drive module 404, with the other end penetrating and extending into the interior of the mixing chamber 300.

[0032] It should be noted that the control unit is connected to the drive module 404. The control unit controls the output shaft of the drive module 404 to rotate at a constant speed. The control unit and its working principle are well known to those skilled in the art, and will not be described in this embodiment.

[0033] Both the outer side of the third shaft 405 and the outer side of the first shaft 401 are fitted with pulleys 406, and the upper and lower pulleys 406 are connected by belt drive.

[0034] Gears 407 are provided on the outer side of the first shaft 401 and the outer side of the second shaft 402, and the gears 407 on the front and rear sides mesh with each other.

[0035] The mixing chamber 300 is a cuboid with a hollow interior and a missing upper surface, used to add an activator into the mixing chamber 300. The lower part of the crushing chamber 100 has a discharge port facing the mixing chamber 300.

[0036] Understandably, the open surface at the top of the mixing chamber 300 is used for the manual or mechanical addition of a measured amount of chemical activator.

[0037] In application, the drive module 404 is activated, and its output shaft directly drives the third shaft 405 to rotate. Since the third shaft 405 and the first shaft 401 are connected to the belt through the pulleys 406 set above and below, the rotational motion of the third shaft 405 is synchronously transmitted to the first shaft 401 through the belt drive. When the first shaft 401 rotates, it drives the second shaft 402 to rotate in the opposite direction and at the same speed through the gear 407 that meshes with the outer side of the second shaft 402. The crushing blades 403 set at equal intervals on the two shafts rotate relative to each other at high speed, which efficiently shears, impacts and grinds the phosphorus slag fed from the top of the crushing chamber 100, and fully crushes it into finer powder with higher activity. Under the action of gravity, the crushed phosphorus slag powder falls continuously and evenly into the mixing chamber 300 through the discharge port facing the mixing chamber 300 at the bottom of the crushing chamber 100. At the same time, a certain amount of chemical activator is added manually or mechanically from the open surface at the top of the mixing chamber 300.

[0038] Example 3:

[0039] The basic content is the same as in Example 1, except that:

[0040] Please see Figure 4-5 In this embodiment, a first stirring blade 408 is provided on the outer periphery of the third shaft 405, and a second stirring blade 409 is provided on the outer periphery of the third shaft 405.

[0041] The first stirring blade 408 and the second stirring blade 409 are both located inside the mixing chamber 300.

[0042] In application, a first stirring blade 408 and a second stirring blade 409 are provided on the outer periphery of the third shaft 405, and they are both located inside the mixing chamber 300. When the power drives the third shaft 405 to rotate at high speed through the belt pulley 406, the first stirring blade 408 and the second stirring blade 409 strongly and mechanically stir the raw and auxiliary materials collected in the chamber.

[0043] In summary, the working principle of this high-activity activation device for phosphorus slag is as follows:

[0044] When the drive assembly is started, it drives the first shaft 401 to rotate. Through the meshing gears 407, the first shaft 401 synchronously drives the second shaft 402 to rotate in the opposite direction and at the same speed. The crushing blades 403 rotate at high speed relative to each other, forming an efficient shearing and grinding action on the phosphorus slag material fed into the crushing chamber 100, which is quickly crushed into fine powder. Under the action of gravity, the crushed phosphorus slag powder falls continuously and automatically into the mixing chamber 300 directly below through the discharge port at the bottom of the crushing chamber 100. At the same time, the operator or the automatic feeding equipment can add a certain amount of chemical activator into the chamber from the open surface at the top of the mixing chamber 300. At this point, the phosphorus slag powder and the activator are collected in the mixing chamber 300.

[0045] The third shaft 405 is equipped with a first stirring blade 408 and a second stirring blade 409 on its outer periphery, both of which are located inside the mixing chamber 300. When the power drives the third shaft 405 to rotate at high speed through the belt pulley 406, the first stirring blade 408 and the second stirring blade 409 strongly and mechanically stir the raw and auxiliary materials collected in the chamber. Through the shearing, convection and diffusion effects generated by the rotation, the agglomeration of the phosphate slag powder that may exist is completely broken, so that it can be fully and uniformly mixed with trace amounts of activator particles. This highly uniform mixture ensures that the surface of the phosphate slag particles can fully contact the activator, providing a fundamental guarantee for efficient pozzolanic reaction and maximizing the potential activity of the phosphate slag in subsequent storage or application.
