TECHNICAL FIELD
[0001] The utility model relates to cement processing technical field, especially a kind of vibration agitating unit. BACKGROUND
[0002] In the production process of building materials, especially for the preparation of water-stable macadam mixture, the traditional mixing method is often difficult to achieve ideal uniformity. This not only reflects the uneven distribution of materials at the macro level, but more seriously at the micro level, cement particles are easy to gather to form "cement groups", and cannot be fully and uniformly dispersed in the entire mixture. This phenomenon can negatively affect the structural strength and durability of the final stabilized soil, thereby affecting the quality of the project.
[0003] In order to overcome the above problems, the prior art has tried various improvement measures, including but not limited to the introduction of continuous double-shaft vibration mixer to enhance the mixing effect. This type of mixer improves the friction and shear force between materials by combining traditional double-shaft mixing technology and vibration technology, which helps to improve the overall uniformity of the mixture. However, even so, it is still found in actual application that the dispersion of cement particles is not ideal.
[0004] Further research shows that using high-efficiency water-reducing agent or dispersant can significantly improve the dispersion of cement particles. The common practice is to directly add additives to the mixer, but this method can easily cause local dispersant concentration to be too high or too low, making it difficult to ensure the sufficient mixing of additives and cement particles.
[0005] In view of this, it is necessary to design a vibration agitating unit that can make the dispersant more evenly distributed in the vibration mixer, avoiding local concentration that is too high or too low, and improving the dispersion of cement particles. SUMMARY

[0032] The embodiment is basically as shown in the attached Figure 1 to the attached Figure 3 :
[0033] The embodiment provides a vibrating stirring device, which comprises a vibrating stirring mechanism body 1 and a dispersant feeding mechanism.
[0034] In the embodiment, the vibrating stirring mechanism body 1 adopts a double-shaft concrete vibrating mixer, and the vibrating stirring mechanism body 1 comprises a rack and a stirring drum, a stirring mechanism and a vibrating mechanism which are mounted on the rack. The stirring drum is mounted on the rack, and the stirring cavity 11 is arranged in the stirring drum. The stirring mechanism comprises a motor, a speed reducer, stirring shafts and blades. A plurality of stirring arms are mounted on the two parallel stirring shafts, and a certain number of stirring blades are fixed on each stirring arm. The motor and the speed reducer provide power for the stirring shafts. The two stirring shafts are located in the stirring cavity 11. When the mixer starts to work, the motor drives the two stirring shafts to rotate towards each other through the speed reducer. The stirring blades rotate with the stirring shafts to form a complex material flow pattern in the stirring drum. On the one hand, the blades push the material from the center to the periphery. On the other hand, the blades lift the material at the bottom to the top to achieve omnidirectional mixing. Due to the double-shaft design, the mixer can achieve high mixing uniformity in a short time, and is especially suitable for processing concrete formulations with high viscosity or containing large particle aggregates. At the same time, the vibrating mechanism is started to apply vibration to the material during stirring.
[0035] The dispersant feeding mechanism comprises a reciprocating driving assembly 2, an agent supply assembly 3 and a spraying assembly 4.
[0036] The reciprocating driving assembly 2 is arranged on the vibrating stirring mechanism body 1 along the length direction of the stirring cavity 11. The driving end of the reciprocating driving assembly 2 is connected with the spraying assembly 4, and is used to drive the spraying assembly 4 to reciprocate along the length direction of the stirring cavity 11. The spraying assembly 4 is located above the stirring cavity 11 and is distributed along the width direction of the stirring cavity 11.
[0037] The agent supply assembly 3 is located outside the vibrating stirring mechanism body 1. The agent supply end of the agent supply assembly 3 is in communication with the liquid inlet end of the spraying assembly 4, and is used to supply the dispersant to the spraying assembly 4.
[0038] The reciprocating drive assembly 2 comprises a mounting frame 21, a motor 22, a lead screw 23, a sliding rod 24 and a lead screw nut 25.
[0039] The mounting frame 21 is fixedly installed on the outer side wall of the vibrating stirring mechanism body 1 along the length direction of the stirring cavity 11, the motor 22 is fixedly installed on the right side wall of the mounting frame 21, the driving end of the motor 22 is connected with the right end of the lead screw 23, the lead screw 23 and the sliding rod 24 are both arranged on the mounting frame 21 along the length direction of the stirring cavity 11, the sliding rod 24 is fixedly connected on the mounting frame 21, the lead screw 23 is rotationally connected on the mounting frame 21, the lead screw nut 25 is threadedly sleeved on the lead screw 23 at the front part, the rear part of the lead screw nut 25 is slidably sleeved on the sliding rod 24, and the bottom of the spraying assembly 4 is fixedly connected on the top of the lead screw nut 25. In this embodiment, the motor 22 is started to drive the lead screw 23 to rotate, and the lead screw nut 25 is driven to move along the sliding rod 24, so that the spraying assembly 4 can reciprocally move along the length direction of the stirring cavity 11, and it is ensured that the dispersing agent can cover the whole stirring area, and when the vibrating stirrer works, the internal material is in a dynamic stirring state, and the dispersing agent uniformly sprayed from the top can be better mixed with the material by turning and vibrating, which helps to improve the uniform distribution degree of the dispersing agent in the mixed material.
[0040] In this embodiment, the reciprocating drive assembly 2 is provided with two groups, and the two groups of reciprocating drive assemblies 2 are arranged on the front and rear side walls of the vibrating stirring mechanism respectively, and the motors 22 on the front and rear sides are synchronously started and stopped, so that the spraying assembly 4 is driven to reciprocally move along the length direction of the stirring cavity 11. By arranging the two groups of reciprocating drive assemblies 2 to drive the spraying assembly 4 to move along the length direction of the stirring cavity 11, the spraying assembly 4 is more stable during the movement.
[0041] As shown in the accompanying drawings, Figure 3 The spraying assembly 4 comprises a support frame 41, a dispersing agent pipe 42 and a spraying head 43.
[0042] The bottom of the support frame 41 is fixedly connected to the drive end of the reciprocating drive assembly 2. The support frame 41 is arranged above the stirring chamber 11 along the width direction of the stirring chamber 11. The dosing tube 42 is fixedly installed on the support frame 41 along the width direction of the stirring chamber 11. The dosing end of the dosing assembly 3 is connected to the liquid inlet of the dosing tube 42. Several spray heads 43 are connected to the bottom of the dosing tube 42. Several spray heads 43 are arranged in an array along the width direction of the stirring chamber 11. In this embodiment, the additive tube 42 is fixed above the mixing chamber 11 by the support frame 41. The additive tube 42 receives the dispersant provided by the agent supply assembly 3, and the dispersant in the additive tube 42 is sprayed into the mixing chamber 11 by several spray heads 43 arranged in an array along the width direction of the mixing chamber 11. This achieves uniform spraying of the dispersant in the mixing chamber 11, avoiding the problem of excessively high or low local concentrations. This makes the cement, crushed stone, water and other components more uniformly mixed under the action of the dispersant, thereby improving the uniformity of the entire mixture.
[0043] In this embodiment, the front and rear ends of the bottom of the support frame 41 are fixedly connected to the top of the lead screw nut 25 on the front and rear sides, respectively.
[0044] The agent supply assembly 3 includes an agent storage tank 31, an agent supply pump 32, and a delivery hose 33;
[0045] The storage tank 31 is located outside the vibrating stirring mechanism. In this embodiment, the storage tank 31 is used to store the dispersant liquid. The outlet of the storage tank 31 is connected to the inlet of the dispersant pump 32 through a delivery hose 33. The dispersant pump 32 is fixedly mounted on the support frame 41, and the outlet of the dispersant pump 32 is connected to the inlet of the dosing pipe 42. In this embodiment, the dispersant pump 32 is mounted on the top of the support frame 41, and the outlet of the dispersant pump 32 is connected to the inlet of the dosing pipe 42 through a short hose. Specifically, the inlet of the dosing pipe 42 is located at the top and middle of the dosing pipe 42. By directly connecting the outlet of the dispersant pump 32 to the inlet of the dosing pipe 42, the dispersant can be efficiently and accurately delivered into the dosing pipe 42, and then evenly sprayed through the spray head 43. By setting up a delivery hose 33, when the dosing tube 42 moves back and forth along the length of the mixing chamber 11, the delivery hose 33 can move back and forth in conjunction with the dosing tube 42, so that the dispersant in the storage tank 31 can be delivered to the dosing tube 42 more conveniently.
[0046] The supply pump 32 is a peristaltic pump. In this embodiment, the supply pump 32 is a peristaltic pump. Peristaltic pumps are compact and lightweight. Due to their unique operating mechanism (propelling fluid forward by squeezing the tubing), peristaltic pumps are very suitable for handling liquids containing small particles or high viscosity, such as dispersants.
[0047] The agent supply assembly 3 further comprises a metering pump 34, which is communicated between the liquid storage tank and the agent supply pump 32. In the embodiment, by communicating the metering pump 34 between the liquid storage tank and the agent supply pump 32, it is ensured that the metering of the dispersing agent drawn from the agent storage tank 31 is accurately measured by the metering pump 34, and then pushed into the agent adding pipe 42 by the agent supply pump 32, and finally sprayed into the stirring chamber 11 by the spray head 43, so as to facilitate the addition of a certain amount of dispersing agent according to the amount of cement particles in the stirring chamber 11.
[0048] Specifically, a flow sensor can also be installed on the agent adding pipe 42 to detect the flow of the dispersing agent in real time. The flow sensor can feed back the detected flow data to the control system. When an abnormal flow is found, the control system can timely adjust the working parameters of the agent supply pump 32 or the metering pump 34, so as to ensure that the flow of the dispersing agent always remains within the set range. This helps to find the possible blockage, leakage and other problems in the agent supply system in time, and take corresponding measures to solve them, so as to ensure the smooth progress of the dispersing agent adding process.
