Description

Technical Field

[0001] The utility model relates to the technical field of extrusion devices, in particular to a foaming agent mixing and extrusion device. Background Technique

[0002] A foaming agent is a substance that makes the target substance form pores. When an aqueous solution of an anionic surfactant introduces air under mechanical force, a large amount of foam is generated. It is often used in the fields of foamed concrete and foamed gypsum boards. When using a foaming agent mixing and extrusion device to manufacture foamed concrete, it is necessary to first foam the foaming agent and then mix the concrete with the foaming agent.

[0003] A foaming agent mixing and extrusion device disclosed in the existing patent (publication number: CN220499896U) includes an equipment tank body, an equipment top cover, a rotating motor, a rotating gear, a connecting rod, a stirring rod A, a stirring rod B, and a rotating block. When the rotating motor on the outer wall of the top of the equipment top cover at the top of the equipment tank body runs, it can drive the connecting rod at its bottom to rotate. The rotation of the connecting rod can drive multiple groups of rotating gears on its outer wall to rotate, driving the stirring rod A and the stirring rod B connected to the bottom of the rotating gear to rotate. Moreover, the rotation of the connecting rod can drive the rotating block inserted into it to rotate, so that the materials in the device can be fully stirred.

[0004] However, the above technical solution still has certain defects. Since during the mixing process, the foaming agent is mixed with the concrete, and the reaction kettle is in a relatively closed environment, the density of the concrete is large, and the foaming agent cannot come into full contact with the air, resulting in the foaming agent being unable to generate enough, thus affecting the quality of the produced foamed concrete. Therefore, a foaming agent mixing and extrusion device is proposed. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a foaming agent mixing and extrusion device to solve the technical problems raised in the above background.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A foaming agent mixing and extrusion device includes a tank body, and an air inflation mechanism extending into the tank body is provided at the top end of the tank body;

[0007] The inflation mechanism includes a first motor fixedly installed at the top end of the tank body. The output end of the first motor is fixedly connected with a pulley group.

The mixing mechanism includes a rotating shaft rotatably connected to the top end of the tank body. One end of the rotating shaft is fixedly connected to the output end of the first motor. The other end of the rotating shaft extends into the tank body.

[0010] As a preferred technical solution of the foaming agent mixing and extruding device of the present utility model, two rotating rods are fixedly connected to the end of the rotating shaft located inside the tank body.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as limiting the present utility model.

[0025] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0026] A foaming agent mixing and extruding device, as Figures 1 to 4As shown, it includes a tank body 1, and an inflation mechanism 2 extending into the interior of the tank body 1 is provided at the top end of the tank body 1;

[0027] The inflation mechanism 2 includes a first motor 201, the first motor 201 is fixedly installed at the top end of the tank body 1, the output end of the first motor 201 is fixedly connected with a pulley group 202, the other end of the pulley group 202 is fixedly connected with a turntable 208, the top end of the turntable 208 is fixedly connected with a slide bar 209, a sliding frame 210 is slidably sleeved on the outer wall of the slide bar 209, two sets of sleeves 203 are fixedly connected to the top end of the tank body 1, a piston 204 is slidably sleeved in the inner wall of each set of sleeves 203, a push rod 205 extending to the outside of the sleeve 203 is fixedly connected to the side wall of each piston 204, one end of the push rod 205 located outside the sleeve 203 is fixedly connected to the side wall of the sliding frame 210, an air inlet 206 is formed in the side wall of the sleeve 203, a pipe 207 is communicated with the side wall of the sleeve 203 and is located below the air inlet 206, an air outlet disc 211 is fixedly connected to the bottom end of the inner wall of the tank body 1, and the end of the pipe 207 is communicated with the side wall of the air outlet disc 211. A first one-way valve 212 is arranged on the inner wall of the sleeve 203, and the position of the first one-way valve 212 coincides with the air inlet 206. A second one-way valve 213 is arranged at the connection of the sleeve 203 and the pipe 207.

[0028] The first motor 201 drives the pulley group 202 to rotate, the pulley group 202 drives the turntable 208 to rotate, the turntable 208 drives the slide bar 209 to rotate, so that the slide bar pushes the sliding frame 210, thereby driving the push rod 205 to slide reciprocally in the inner wall of the sleeve 203. During the reciprocal sliding of the push rod 205, the piston 204 is driven to slide reciprocally. When the piston 204 moves away from the air inlet 206, the negative pressure inside the tank body 1 causes the first one-way valve 212 to open and the second one-way valve 213 to close, so that air enters the inside of the sleeve 203 from the air inlet 206. When the piston 204 approaches the first one-way valve 212, the air inside the sleeve 203 is compressed, causing the first one-way valve 212 to close and the second one-way valve 213 to open. Thus, as the piston 204 approaches the pipe 207, the air is pushed into the pipe 207, and the air is ejected from the air outlet disc 211, so that the foaming agent and the concrete can be in full contact with air during the mixing process.

[0029] Please refer specifically to Figure 1 and 2, a mixing mechanism 3 is provided on the inner wall of the tank body 1. The mixing mechanism 3 includes a rotating shaft 301. The rotating shaft 301 is rotatably connected to the top end of the tank body 1. One end of the rotating shaft 301 is fixedly connected to the output end of the first motor 201. The other end of the rotating shaft 301 extends into the tank body 1. Two groups of rotating rods 302 are fixedly connected to the end of the rotating shaft 301 located inside the tank body 1. Two groups of auxiliary shafts 305 are rotatably connected between the two groups of rotating rods 302. One group of gear sets 304 is provided at the top end of each group of auxiliary shafts 305. A toothed ring 303 is fixedly sleeved on the inner wall of the tank body 1. The toothed ring 303 is meshed with the gears in the two groups of gear sets 304 at the same time. Multiple groups of stirring rods 306 are fixedly connected to the side walls of each group of auxiliary shafts 305. A discharge port 307 is opened at the bottom end of the tank body 1. An auger 308 is rotatably connected to the inner wall of the discharge port 307. A second motor 309 is fixedly installed at the bottom end of the tank body 1. The output end of the second motor 309 is coaxially connected to the auger 308.

[0030] During the rotation of the pulley group 202, the rotating shaft 301 is driven to rotate. The rotating shaft 301 drives the rotating rod 302 to rotate, so that the rotating rod 302 drives the auxiliary shaft 305 and the gear set 304 to rotate. During this process, since the gear set 304 is meshed with the toothed ring 303, the gear set 304 drives the auxiliary shaft 305 to rotate self. During the self-rotation of the auxiliary shaft 305, the stirring rod 306 is driven to rotate self, so that the stirring rod 306 rotates around the rotating shaft 301 and the auxiliary shaft 305 in the tank body 1 for revolution and self-rotation, so that the concrete and the foaming agent in the tank body 1 can be fully stirred and mixed. When the concrete and the foaming agent are mixed evenly, the second motor 309 drives the auger 308 to rotate, so that the mixed concrete is discharged through the discharge port 307.

[0031] During use, the first motor 201 drives the piston 204 to reciprocate inside the sleeve 203, so that air is ejected from the air outlet disc 211. Thus, during the mixing process of the foaming agent and the concrete, air continuously enters the mixture of the two, so that the foaming agent can fully contact with air during the mixing process with the concrete, ensuring the foaming effect. The parts not involved in this device are the same as the prior art or can be realized by using the prior art.
