Description

Technical Field

[0001] The invention relates to the technical field of concrete foaming equipment, and in particular to a full-automatic hydraulic mortar concrete foaming equipment. Background Art

[0002] Concrete, abbreviated as "concrete (tóng)", is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. In civil engineering, cement is commonly used as a cementitious material, sand and stone are used as aggregates, and water (which may contain admixtures and additives) is mixed in a certain proportion and mixed to obtain cement concrete, also known as ordinary concrete. Foamed concrete, also known as foamed concrete, is a new type of lightweight thermal insulation material made through a specific process. The foaming agent is fully foamed mechanically through the foaming system of the foaming machine, and the foam is evenly mixed with the cement slurry, and then cast-in-place construction or mold forming is carried out through the pumping system of the foaming machine. After natural curing, a material containing a large number of closed pores is formed. This material forms closed foam pores inside the concrete, which makes it lightweight and thermally insulating.

[0003] After searching, the invention patent with Chinese patent number CN114714509B discloses a double-foaming foam concrete equipment, including a cylinder and a mixing part installed in the cylinder, the mixing part divides the cylinder into a feeding chamber and a discharging chamber; a rotating shaft is rotatably connected in the feeding chamber, a feeding plate connected to the cylinder horizontally slidingly is coaxially threadedly connected on the rotating shaft, a first driving member is installed on the cylinder, and the output shaft of the first driving member is coaxially fixedly connected with the rotating shaft; a stirring shaft is rotatably connected in the discharging chamber, a plurality of stirring blades are installed on the stirring shaft along its axial direction, a second driving member is installed on the cylinder, and the output shaft of the second driving member is coaxially fixedly connected with the stirring shaft; a plurality of connecting parts are arranged on the mixing part along its circumference, the connecting part connects the feeding chamber and the stirring chamber, and a medicine feeding part and an air inlet part installed on the cylinder are arranged on the outer periphery of the mixing part, and both the medicine feeding part and the air inlet part are connected with the connecting part. The invention has a simple structure, and can double-foam the foam concrete and improve the efficiency of concrete foaming.

[0004] However, in actual use of the above device, concrete, pressurized gas and foaming agent are simultaneously foamed and mixed in the throat section. When the high-speed gas meets the concrete slurry in the narrow throat section, the size of the bubbles formed is difficult to control, which may cause the bubbles to be too large or too small, affecting the density and mechanical properties of the foamed concrete. Once the equipment is running, it will be difficult to adjust the mixing conditions (such as gas flow rate, foaming agent flow rate), which will easily affect the concrete foaming efficiency. Therefore, a fully automatic hydraulic mortar concrete foaming equipment is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that concrete, pressurized gas and foaming agent are simultaneously foamed and mixed in the throat section, and the size of the bubbles formed when the high-speed gas meets the concrete slurry in the narrow throat section is difficult to control, which may cause the bubbles to be too large or too small, affecting the density and mechanical properties of the foamed concrete. Once the equipment is running, it will be difficult to adjust the mixing conditions (such as gas flow rate, foaming agent flow rate), which is easy to affect the concrete foaming efficiency. A fully automatic hydraulic mortar concrete foaming equipment is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A hydraulic pipe is provided on the side of the foaming cylinder away from the stirring rod, a hydraulic cylinder is provided below the hydraulic pipe, a mixing cylinder is fixedly connected to the side of the hydraulic pipe away from the foaming cylinder, a mixing mechanism is provided outside the mixing cylinder, the mixing mechanism includes a second motor provided outside the mixing cylinder, a second stirring fan is provided at the output end of the second motor, a concrete slurry mixing cylinder is provided above the base, a transmission pipe is fixedly connected to the side of the concrete slurry mixing cylinder, and the operation of the second motor causes the second stirring fan to rotate to automatically mix the fine foam and concrete slurry inside the mixing cylinder.

[0009] The above technical solution further includes:

[0010] The mechanical support is fixedly connected to the first motor, a fixed plate is fixedly connected to the side of the bearing rod, the fixed plate is rotatably connected to the stirring rod, the first stirring fan is arranged inside the foaming cylinder, a support frame is fixedly connected to the side of the base close to the mechanical support, and the support frame is fixedly connected to the foaming cylinder.

[0011] A second cam wheel disc is arranged on the side of the first motor away from the first cam wheel disc, the second cam wheel disc is rotatably connected to a transmission rod on the side, the transmission rod is rotatably connected to a connecting bearing on the side away from the second cam wheel disc, and a pressure block is fixedly connected to the connecting bearing on the side away from the transmission rod.

[0012] The side of the pressure block is slidably connected with an air cylinder, and the side of the air cylinder away from the pressure block is fixedly connected with an air pipe, and the air pipe is fixedly connected to the foaming cylinder.

[0013] A feed inlet is arranged above the foaming cylinder, and the feed inlet is used for putting in the foaming agent.

[0014] A water pump is fixedly installed on one side of the foaming cylinder below the foaming cylinder and close to the hydraulic cylinder, and the water pump can transport water into the foaming cylinder;

[0015] Wherein, the water pump can be used to cooperate with the foaming mechanism and the mixing mechanism to clean the inside of the device.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, the first motor drives the first convex wheel to rotate, the first convex wheel drives the connecting piece to move in an offset manner, the connecting piece drives the stirring rod to move, and the stirring rod drives the stirring fan to stir at different positions inside the foaming cylinder.

[0022] 2. In the present invention, the design of the hydraulic cylinder and the hydraulic pipe enables the fine bubbles after foaming to be stably and continuously transmitted to the mixing drum. The rotation of the second stirring fan in the mixing drum ensures the full mixing of the fine bubbles and the concrete slurry, so that the uniformity and consistency of the concrete foaming are significantly improved. This two-stage foaming and mixing process not only improves the overall quality of the foamed concrete, but also significantly enhances its density and mechanical properties. It is relatively simple to adjust the mixing conditions (such as gas flow rate, foaming agent flow rate) and will not affect the foaming efficiency of the concrete, thereby realizing the fully automatic integrated function of concrete from slurry formation to foaming molding.
