Abstract
Description
Technical Field
[0001] The utility model provides a foamed concrete mixing equipment, belonging to the technical field of foamed concrete production. Background Art
[0002] Foamed concrete, also known as aerated concrete, is a special variety of aerated concrete. Its pore structure and material properties are close to those of aerated concrete. The difference between the two lies only in the pore shape and aeration method. When producing foamed concrete, mixing equipment is usually required to uniformly mix various raw materials together.
[0003] Existing mixing equipment can basically meet the normal use requirements of foamed concrete production. However, since the main raw materials in foamed concrete, namely the foaming agent and foam stabilizer, usually need to be foamed first using a special foaming machine, and then the foam is transported to the mixing equipment using a foam transfer pump for mixing with other raw materials such as cement, not only is the operation time-consuming and laborious, but the transported foam accumulates on one side, reducing the mixing efficiency, and also because a special foaming machine is required, the comprehensive cost is relatively high. Based on this, the utility model provides a foamed concrete mixing equipment. Summary of the Utility Model
[0004] The technical problem solved by the utility model is that due to the need to use a special foaming machine, not only is the operation time-consuming and laborious, the transported foam accumulates on one side, reducing the mixing efficiency, but also the comprehensive cost is relatively high.
[0005] To solve the technical problem, the technical solution provided by the utility model is: a foamed concrete mixing equipment, including a mixing tank. A foaming barrel is provided on the inner top wall of the mixing tank. A mixing component is provided in the mixing tank. A motor for driving the mixing component is provided on the top of the mixing tank. The mixing component includes a mixing rod rotatably connected to the bottom wall of the foaming barrel. A first set of mixing blades is equidistantly provided on the lower rod body of the mixing rod. A second set of mixing blades placed in the foaming barrel is equidistantly provided on the upper rod body of the mixing rod. An annular spray pipe is provided on the outer bottom wall of the foaming barrel outside the mixing rod. A foaming agent transfer pump communicated with the annular spray pipe is provided on one side of the inner bottom wall of the foaming barrel. A plurality of nozzles are equidistantly provided at the bottom of the annular spray pipe.
[0006] Further, a first feed inlet communicated with the mixing tank is provided on one side of the top of the mixing tank. A second feed inlet communicated with the foaming barrel is provided on the other side of the top of the mixing tank. A discharge outlet is provided at the bottom of the mixing tank.
[0007] Further, an observation window is provided on the side wall of the mixing tank.
[0008] Further, the output end of the motor is inserted into the mixing tank and fixedly connected to the top of the mixing rod.
[0009] Furthermore, a bearing is provided between the bottom wall of the foaming barrel and the body of the stirring rod for rotational connection.
[0010] Furthermore, the foaming agent delivery pump and the annular spray pipe are connected through a delivery pipe. An inlet is provided on one side wall of the foaming agent delivery pump and is located on one side of the second stirring blade.
[0011] Advantages of the present utility model:
[0012] Through the operation of the stirring assembly, the first stirring blade stirs raw materials such as cement evenly, and the second stirring blade stirs and mixes the foaming agent and the foam stabilizer to generate foam. Then, by starting the foaming agent delivery pump, the foam in the foaming barrel is evenly sprayed onto the four sides inside the stirring tank through multiple nozzles. The foaming work can be achieved without using a dedicated foaming machine, reducing the comprehensive cost. Moreover, the foaming work can be carried out while stirring raw materials such as cement, saving time and effort in operation, preventing the foam from being accumulated on one side, and effectively improving the work efficiency.

There is a foaming barrel 2 on the inner top wall of the mixing tank 1. On one side of the top of the mixing tank 1, there is a first feeding port 11 communicating with the mixing tank 1. On the other side of the top of the mixing tank 1, there is a second feeding port 12 communicating with the foaming barrel 2. At the bottom of the mixing tank 1, there is a discharge port 13. A mixing component 3 is arranged in the mixing tank 1, and a motor 4 for driving the mixing component 3 is arranged on the top of the mixing tank 1. The mixing component 3 includes a mixing rod 5 rotatably connected to the bottom wall of the foaming barrel 2. At equal intervals on the lower rod body of the mixing rod 5, there are first mixing blades 6. At equal intervals on the upper rod body of the mixing rod 5, there are second mixing blades 7 placed in the foaming barrel 2. The output end of the motor 4 is inserted into the mixing tank 1 and fixedly connected to the top of the mixing rod 5. Between the bottom wall of the foaming barrel 2 and the rod body of the mixing rod 5, they are rotatably connected through a bearing 15 to ensure that the mixing rod 5 can rotate effectively. By adding raw materials such as cement and water reducing agent from the first feeding port 11 into the mixing tank 1, and adding foaming agent and foam stabilizer from the second feeding port 12 into the foaming barrel 2, starting the motor 4 drives the mixing rod 5 to rotate, and then drives the first mixing blades 6 and the second mixing blades 7 to rotate.

At equal intervals on the bottom of the annular spray pipe 8, there are a plurality of nozzles 10. The foaming agent delivery pump 9 and the annular spray pipe 8 are connected through a delivery pipe 16. On one side wall of the foaming agent delivery pump 9, there is an inlet 17 placed on one side of the second mixing blades 7. By starting the foaming agent delivery pump 9, the foam in the foaming barrel 2 is transported to the annular spray pipe 8 through the inlet 17 and the delivery pipe 16, and is evenly sprayed onto the four sides inside the mixing tank 1 through the plurality of nozzles 10, so as to prevent the transported foam from accumulating on one side.
[0020] According to the attached Figure 1 As shown in the figure: There is an observation window 14 on the side wall of the mixing tank 1, which plays a role in conveniently observing the mixing situation of the internal foam concrete.
