In the concrete production process, it is necessary to add a variety of different admixtures to the raw materials to improve the performance of concrete. However, admixtures need to be added in a quantitative manner. The existing operation method is to manually weigh and add them to the mixing barrel, which is time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] like Figure 1-Figure 3 As shown, the utility model provides a device for quantitatively adding liquid concrete admixtures, which includes a frame 1, a stirring assembly, a horizontal plate 11, a weighing tank 12 and a material guide pipe 15.

[0024] Transparent dustproof plates are provided on the inner sides of the openings on both sides of the frame 1, and two supporting feet are symmetrically provided at the bottom of the frame 1, and mounting holes are provided on the supporting feet. A plurality of storage barrels 2 are provided on the frame 1, and a flip cover 5 is rotatably provided on the top cover of the storage barrel 2, and a lifting handle is provided on the flip cover 5. A vent hole 201 connected to the inside of the storage barrel 2 is provided on the top cover, and a one-way valve for air intake only is provided in the vent hole 201. A feed pipe A3 connected to the inside of the storage barrel 2 is provided at the bottom, and a solenoid valve A4 is provided in the feed pipe A3. A stirring assembly is provided in the storage barrel 2, and a motor A10 for driving the stirring assembly to rotate is provided on the frame 1. The stirring assembly includes a rotating shaft 6, an agitator 7, a belt 9 and a coupling. The agitator 7 is arranged on the rotating shaft 6 and is located in the storage barrel 2. The rotating shaft 6 penetrates the top cover of the storage barrel 2 and is rotatably connected thereto. A double-groove pulley 8 is arranged on the rotating shaft 6. Two adjacent double-groove pulleys 8 are connected by a belt 9. The output end of the motor A10 is connected to the end of one of the rotating shafts 6 by a coupling. A fixing frame is also included. The fixing frame is connected to the top cover of each storage barrel 2. The top end of each rotating shaft 6 penetrates the fixing frame and is rotatably connected thereto. The motor A10 is arranged on the fixing frame.

[0025] The horizontal plate 11 is arranged on the inner side of the frame 1, and a plurality of weighing slots 111 are arranged on the horizontal plate 11, and a gravimeter is arranged on the edge of the weighing slot 111. The weighing tank 12 is slidably arranged on the inner side of the weighing slot 111, and a convex ring is arranged on the outer edge of the weighing tank 12, and the convex ring falls on the detection end of the gravimeter. A feeding pipe B13 connected to the weighing tank 12 is arranged at the bottom, and a solenoid valve B14 is arranged in the feeding pipe B13. The guide pipe 15 is arranged on the inner side of the frame 1, and a plurality of feeding pipes 16 connected to the inside thereof are arranged on the guide pipe 15, and each feeding pipe B13 is respectively inserted into the corresponding side feeding pipe 16 and slidably connected thereto, and a discharging pipe 17 connected to the inside thereof is arranged at the bottom of the guide pipe 15.

[0026] In this embodiment, a variety of different admixtures are placed in the corresponding storage barrels 2 respectively. When the admixture needs to be added, the addition amount of the corresponding admixture is set first, and then the electromagnetic valve A4 in the discharge pipe A3 of the corresponding storage barrel 2 automatically opens and discharges the material. The admixture enters the weighing tank 12 and starts to be weighed. When the weight reaches a certain amount, the electromagnetic valve A4 on this side is automatically shut off, and the electromagnetic valve B14 automatically opens and discharges the material to enter the guide pipe 15. The admixture enters the concrete mixing barrel along the guide pipe 15 and the discharge pipe 17 to participate in the reaction. Since the concrete mixing reaction time is long, the admixture inside and outside the storage barrel 2 is in a long-term static state. At this time, the motor A10 is started in time and drives the agitator 7 in each storage barrel 2 to rotate at the same time, and the agitator 7 is used to drive the admixture to prevent the admixture from being stratified due to long-term static reaction.

[0027] Embodiment 2

[0028] like Figure 1 and Figure 4 As shown, the utility model proposes a liquid concrete admixture quantitative addition device. Compared with the first embodiment, an auger 18 is rotatably arranged in the material guide pipe 15, the auger 18 is gap-matched with the inner wall of the material guide pipe 15, and a motor B19 for driving the auger 18 to rotate is arranged on the end cover of the material guide pipe 15.

[0029] In this embodiment, during the process of conveying the additive through the material guide pipe 15, the motor B19 drives the auger 18 to rotate, and the auger 18 is used to clean the inner wall of the material guide pipe 15 to prevent the additive from adhering to the inner wall of the material guide pipe 15. On the one hand, it can prevent the residual additive in the pipe from affecting the ratio balance of the next batch of additives, and on the other hand, it can also prevent the total amount of the current additive from being added to the mixing barrel.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
