Description

Technical Field

[0001] This utility model mainly relates to the field of foaming material mixing equipment, specifically a lightweight foaming material mixing device. Background Technology

[0002] Foamed concrete is a type of concrete material that incorporates a foaming agent into cementitious materials, fine aggregates, and a water system. Through physical or chemical foaming methods, tiny, closed, uniform air bubbles are generated within the concrete, resulting in a lightweight, heat-insulating, fire-resistant, sound-insulating, and freeze-thaw resistant concrete material. Due to its numerous superior properties, foamed concrete has attracted significant attention both domestically and internationally for its research and development.

[0003] In common methods, foam is first prepared by mechanically using a foaming agent aqueous solution. The foam is then added to a slurry composed of siliceous materials, calcareous materials, water, and various additives. After mixing, casting, and curing, the foam is formed. Existing mixing devices are generally of traditional structure. After the material enters the mixing device, it is discharged through the pipe. During the discharge process, the foaming material is compressed, which can easily lead to the loss of air bubbles inside the material. In addition, traditional foaming operations all use foaming agents, and high-quality foaming agents are generally expensive, which increases the preparation cost of foamed concrete and is not conducive to the widespread promotion of foamed concrete. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lightweight foaming material mixing device. Its main advantages are: by incorporating an openable and closable mixing cover structure and a liftable feed tray structure, the initial material can be evenly fed into the mixing tank through densely packed feed holes at the bottom of the feed tray. The mixing device and agitator structure within the mixing cover structure further agitate the inside of the mixing tank. After agitation, opening the mixing cover structure and lowering the feed tray structure allows the material to be completely discharged from the bottom of the device, preventing foam loss due to pipe compression during discharge. Furthermore, the agitator and agitator structure can be raised and lowered, preventing interference with the opening and closing of the mixing cover during descent. This height adjustment further ensures more uniform mixing of the material inside the mixing tank. Simultaneously, air intake structures are integrated on both sides of the agitator to replace the foaming agent for air foaming within the material.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A lightweight foaming material mixing device includes a mixing tank. A tank cover pivot seat is fixedly provided on one side of the bottom of the mixing tank. A rotating tank cover is fitted around the outer periphery of the tank cover pivot seat and is rotatably and slidably connected to it. A sealing pivot sleeve is provided at the center of the rotating tank cover. A mixing pivot rod is provided inside the sealing pivot sleeve and is rotatably connected to it. A mixing motor is coaxially fixedly connected to the lower end of the mixing pivot rod. A hydraulic cylinder support plate is fixedly provided on one side of the mixing motor. A supporting hydraulic cylinder is fixedly provided on the upper side of the hydraulic cylinder support plate. The bottom of the supporting hydraulic cylinder is fixedly connected to the rotating tank cover. A plurality of mixing pivot paddles are fitted around the outer periphery of the mixing pivot rod. Air nozzles are fixedly provided on both sides of the mixing pivot paddles and communicate with the mixing pivot rod. An air inlet valve is provided on one side of the mixing motor and communicates with the mixing pivot rod.

[0007] Furthermore, the upper center of the mixing tank has a feed coil hole, and a feed coil is slidably fitted inside the feed coil hole. A feed plate is fixedly installed at the bottom of the feed coil and communicates with it. Several grooves are formed on the outer periphery of the feed plate. A sliding strip is fixedly installed inside the mixing tank at a position corresponding to the groove and is slidably connected to it. Several feed holes are densely arranged at the bottom of the feed plate. A moving rack is fixedly installed on one side of the feed coil. A lifting motor box is fixedly installed on one side of the upper part of the mixing tank. A lifting motor is installed inside the lifting motor box. A gear is fixedly fixedly installed on the output end of the lifting motor and meshes with the moving rack. A feed pump is fixedly installed on the upper part of the feed coil and communicates with it.

[0008] Furthermore, a support frame connecting rod is fixedly provided on both sides of the mixing tank, and a mixing tank support frame is rotatably connected to the outer periphery of the support frame connecting rod. A mixing tank tilting handle is fixedly provided on one side of the mixing tank, and a lid handle is fixedly provided on both sides of the bottom of the rotating lid. Bolt plates are fixedly provided at corresponding positions on the rotating lid and one side of the mixing tank, and fixing bolts are provided inside the bolt plates on both sides.

[0009] Compared with the existing technology, the beneficial effects of this utility model are:

[0010] 1. By setting an openable and closable mixing cover structure and a lifting and lowering feeding plate structure, the initial material can be evenly fed into the mixing tank through the densely packed feeding holes at the bottom of the collecting plate. The mixing device and mixing paddle structure inside the mixing cover structure further mix the inside of the mixing tank. After mixing, the mixing cover structure is opened and the feeding plate structure is lowered so that the mixed material is completely discharged from the bottom of the equipment. This ensures that the foaming material inside is not squeezed by the pipe during discharge, thus preventing foam loss.

[0011] 2. Further, the mixer and mixing paddle structure can be raised and lowered, so that it can prevent the opening and closing of the mixing cover from being affected when it is lowered. The raising and lowering of the paddle can further make the materials inside the mixing tank more uniformly mixed. At the same time, the air intake structure of the nozzle is integrated on both sides of the mixing paddle to replace the foaming agent to perform air foaming operation inside the material.

Several feed holes 17 are densely arranged at the bottom of the feed plate 14. Material to be mixed is introduced into the feed coil 13, allowing it to enter the feed plate 14 and be discharged into the mixing tank 1 through the densely arranged feed holes 17 at the bottom of the feed plate 14. A movable rack 18 is fixedly provided on one side of the mixing tank 1, and a lifting motor box 19 is fixedly provided on one side of the upper part of the mixing tank 1. A lifting motor 20 is provided inside the lifting motor box 19. A gear 21 is fixedly fixed on the output end of the lifting motor 20 and meshes with the movable rack 18.

[0030] Working principle:

[0031] In use, the rotating barrel cover 3 is first fixed to the bottom of the mixing barrel 1 using the fixing bolts 28. Then, the material to be mixed is introduced into the mixing barrel 1 via the feed pump 22. Next, the mixing motor 6 is started, driving the mixing shaft 5 to rotate and causing the mixing shaft paddle 9 to stir the inside of the mixing barrel 1. Simultaneously, the supporting hydraulic cylinder 8 drives the mixing shaft 5 to rise and fall synchronously, allowing the mixing shaft paddle 9 to stir inside the mixing barrel 1 while simultaneously rising and falling, resulting in more uniform stirring. At the same time, air is introduced into the air inlet valve 11, and the air is then... The nozzle 10 is inserted into the mixing tank 1 to inflate and foam the material inside. After mixing, the fixing bolt 28 is opened to open the rotating tank cover 3, and the mixing tank 1 is tilted by the mixing tank tilting handle 25. Then, the lifting motor 20 is controlled to drive the gear 21 to rotate. The gear 21 meshes with the moving rack 18, thereby driving the feeding coil 13 to descend and the feeding plate 14 to descend. After the material inside the mixing tank 1 is mixed, it is discharged from the bottom of the mixing tank 1 through the feeding plate 14, completing the foaming material mixing operation.
