Description

Technical Field

[0001] The utility model relates to the technical field of concrete additive processing devices, in particular to an intelligent concrete additive batching device. Background Art

[0002] Concrete admixtures refer to substances added to improve and adjust the performance of concrete. Concrete admixtures are divided into four categories according to their main functions: admixtures that improve the rheological properties of concrete mixtures, including various water reducers, air entraining agents and pumping agents; admixtures that adjust the setting time and hardening properties of concrete, including retarders, early strength agents and accelerated setting agents; admixtures that improve the durability of concrete, including air entraining agents, waterproofing agents and rust inhibitors; admixtures that improve other properties of concrete, including air entraining agents, expansive agents, colorants, antifreeze agents, waterproofing agents and pumping agents.

[0003] Among them, water reducer is a commonly used concrete admixture, which is used to reduce the water-cement ratio of concrete, improve the plasticity and fluidity of concrete, and increase the strength of concrete. Taking the production of polycarboxylic acid water reducer as an example, the raw materials of polycarboxylic acid water reducer include polycarboxylic acid base material, external processing aids and other auxiliary components, such as additives, stabilizers and antifreeze agents. The production process of polycarboxylic acid water reducer is as follows: add water, start stirring, and add polycarboxylic acid base material; after reaching the specified temperature, add external processing aids and other auxiliary components in sequence; replenish water, stir for a period of time and then discharge the material. In the process of mixing and proportioning the raw materials of polycarboxylic acid water reducer, the polycarboxylic acid base material is generally manually added into the mixing tank, and the external processing aids and other auxiliary components are quantitatively added by an automatic quantitative feeding device. When the polycarboxylic acid base material is added, the fixed feeding position causes the polycarboxylic acid base material to contact with water and form a mass, so that the polycarboxylic acid base material and water need a long time to be dispersed and mixed. Based on this, in order to further improve the mixing efficiency of the polycarboxylic acid base material and water, an intelligent concrete additive batching device is provided.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 4 In an embodiment of the utility model, an intelligent concrete additive batching device includes a mixing tank 1 consisting of a tank body 101, a feeding port 102 and a quantitative feeding pipe 103. The feeding port 102 is welded and fixed to the top of the tank body 101. The quantitative feeding pipe 103 is connected to the top of the tank body 101 and is staggered with the feeding port 102. A stirring assembly 2 including a main shaft 202 is arranged inside the tank body 101. The stirring assembly 2 is used to mix and stir the raw materials inside the tank body 101. A bulk material assembly 3 is arranged outside the main shaft 202. The bulk material assembly 3 is used to disperse and discharge the base material fed from the feeding port 102.

[0025] The bulk material assembly 3 includes a rotating disk 301, a material drop chute 302, a material shifting piece 303 and a dispersing port 304;

[0026] The rotating disk 301 is fixed to the outside of the main shaft 202. The bottom of the feeding port 102 extends to the inside of the tank 101 and is located above the rotating disk 301. The rotating disk 301 is used to receive the base material fed from the feeding port 102 and the rotating rotating disk 301 drives the base material to move synchronously.

[0027] The material dropping groove 302 is opened at the top of the rotating disk 301 and passes through the bottom of the rotating disk 301. The base material falls into the bottom of the tank body 101 through the staggered material dropping grooves 302 to achieve dispersed contact with water;

[0028] The material shifting piece 303 is fixed to the inner side of the tank body 101 and is attached to the top of the rotating disk 301. The dispersing opening 304 is provided at the bottom of the material shifting piece 303. The material shifting piece 303 performs a shifting operation on the base material on the top of the tank body 101 through the physical part between two adjacent dispersing openings 304, so as to realize the complete material unloading operation of the base material on the top of the tank body 101.

[0029] The stirring assembly 2 also includes a driving motor 201 and a stirring blade 203;

[0030] The driving motor 201 is fixedly installed at the top center of the tank body 101, and the output end of the driving motor 201 passes through the tank body 101 and is fixedly connected to the main shaft 202;

[0031] A plurality of stirring blades 203 are provided, and the plurality of stirring blades 203 are circumferentially fixed to the outside of the main shaft 202 and are located below the rotating disk 301 .

[0032] In this embodiment: it should be supplemented that: a plurality of quantitative feeding pipes 103 are provided, and the plurality of quantitative feeding pipes 103 are respectively connected to the storage tanks of water, external processing aids, and other auxiliary components through quantitative pumps, and the quantitative addition operation of water, external processing aids, and other auxiliary components can be realized by controlling the operation of each quantitative pump;

[0033] When mixing the water reducing agent, a certain amount of water is first delivered to the tank 101, and then the driving motor 201 is started, and the driving motor 201 drives the main shaft 202, the stirring blade 203, and the rotating disk 301 to rotate synchronously. At the same time, the base material is manually fed from the feeding port 102, and the base material falls on the top of the rotating disk 301, so that the base material is evenly laid on the top of the rotating disk 301;

[0034] In this process, part of the base material will fall onto the water surface from some of the drop grooves 302 at the beginning, while another part of the base material will accumulate on the top of the rotating disk 301 and rotate with the rotating disk 301. When this part of the base material contacts the material-digging piece 303, it will be blocked by the material-digging piece 303, so that the base material will gather toward the dispersion port 304. Since the position of the dispersion port 304 corresponds to the position of different drop grooves 302, the base material will approach the drop groove 302, and then the base material on the top of the rotating disk 301 will be dropped for the second time. At this time, part of the base material will not fall, so when it encounters the second material-digging piece 303, the base material will be dropped for the third time. In this way, the base material can be dispersed and fall onto the water surface, and the rotating stirring piece 203 can make the base material and water fully mixed.

[0035] Compared with the traditional one-time feeding operation, the mixing efficiency of the dispersed base material and water is faster, which can further improve the production efficiency of the water reducing agent.

[0036] Please refer to Figures 2 to 4 There are multiple types of blanking slots 302, including but not limited to: round holes, straight slots, arc-shaped slots, and each type of blanking slots 302 is provided with multiple groups, and the multiple blanking slots 302 are staggered and distributed in a circular manner;

[0037] There are multiple material-shifting pieces 303, which are circumferentially fixed to the inner side of the tank body 101. The number of dispersion openings 304 on the multiple material-shifting pieces 303 is different, and the positions of the dispersion openings 304 on the multiple material-shifting pieces 303 correspond to the distribution positions of the multiple material-dropping slots 302.

[0038] The bottom of the last material-diverting piece 303 located near the feeding port 102 along the rotating direction of the rotating disk 301 is not provided with a dispersion port 304 for intercepting the base material.

[0039] In this embodiment: the base material can be better dispersed and dropped into the water surface by means of the multiple material dropping grooves 302 distributed in a staggered circumference, and the corresponding dispersion openings 304 on the multiple material-dispensing pieces 303 can be used to separate the base material into multiple drops, thereby achieving a better dispersion effect of the base material;

[0040] The last material-discharging piece 303 without the dispersing opening 304 can intercept the base material, and the base material can be completely discharged in coordination with the staggered material-discharging grooves 302 to avoid base material residue.

[0041] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
