Description

Technical Field

[0001] The invention relates to the technical field of concrete preparation, in particular to a foam concrete stirring kettle. Background Art

[0002] Foam concrete is a new type of civil engineering material. It's typically prepared from cementitious materials, water, admixtures, and foam in a specific ratio, then uniformly mixed and cured to harden the stone. Due to its abundant raw materials, low price, lightweight material, and excellent thermal insulation and shock absorption properties, foam concrete is attracting increasing research. To prepare foam concrete, the cementitious materials, water, and admixtures are first placed in a mixing tank and stirred. A certain volume of foam is then added and stirred again.

[0003] Currently, foam concrete preparation lacks a dedicated mixing kettle. Instead, the existing mortar mixing kettle is used. The mixing process is simple and requires removing the mixing kettle, pumping the foam into a measuring cup, and then adding it to the mixing kettle. This is complex, and the foam easily sticks to the inside of the measuring cup, making volume control difficult. Furthermore, due to the high viscosity and low density of the foam added in the experiment, it easily floats and sticks to the inner wall of the mixing kettle during mixing, affecting the efficiency and effectiveness of the experiment. Therefore, a mixing kettle was proposed to address these issues. Summary of the Invention

[0004] The object of the present invention is to provide a foam concrete mixing kettle to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: comprising a stirring kettle body and a stirring kettle assembly, the stirring kettle assembly comprising a motor, a fan handle, a stirring fan, a spiral positioner, a stopper, a control rod, and a scraper disc, wherein the motor is arranged above the stirring kettle body, the upper end of the fan handle is fixed to the motor output end, the stirring fan is fixed to the lower end of the fan handle, the spiral positioner is fixed to the side wall of the fan handle, the spiral positioner is provided with a circle of guide rails, the bottom surface of the guide rails being higher on one side than on the other side, and a transitional inclined surface is provided between the two sides, the stopper is provided with two limit wheels, the two limit wheels are respectively located on the upper and lower sides of the head and tail connecting threads and clamp the guide rails, the control rod is fixedly connected to the stopper, the scraper disc is fixed to the lower end of the control rod, and the outer edge of the scraper disc is in close contact with the inner wall of the stirring kettle body.

[0006] Furthermore, the scraper disc is made of a transparent material and is provided with a disc feed hole, which passes through the scraper disc, and the inner wall of the stirring kettle body is provided with volume scale lines.

[0007] Furthermore, the outer edge of the scraper disc is adhered with rubber, and the outer edge of the scraper disc is in close contact with the inner wall of the stirring kettle body.

[0009] Furthermore, the stirring fan also includes fan blades, which are arranged at the lower end of the fan handle. A horizontal straight rod is arranged at the top of the fan blade, and a plurality of oblique rods are arranged in the middle of the fan blade.

[0010] Furthermore, the lower part of the stirring kettle body is provided with a spiral base, which can be detachably mounted on a bracket of a common mortar mixer.

[0011] Furthermore, a feeding port penetrating the stirring kettle body is fixedly installed on one side of the stirring kettle body, and a pair of arc-shaped ears are installed on both sides of the stirring kettle body.

[0012] Compared with the prior art, the present invention has the following advantages: (1) The present invention provides a volume scale and a feeding port on the main body of the mixing kettle by means of a positioning frame, which can quantitatively control the amount of foam added during the preparation of foam concrete. The foam can be directly pumped in, thus avoiding the problem of foam sticking to the container in ordinary tests, in which the foam is first pumped into a measuring cup and then added to the mortar mixing kettle.

[0013] (2) The present invention scrapes the materials sticking to the inner wall of the mixing kettle body by using a scraping disc, thereby preventing foam and other materials from remaining on the inner wall of the mixing kettle body and affecting the preparation effect of foamed concrete.

[0014] (3) The present invention cooperates with the spiral positioner and the limiter so that when the motor drives the stirring fan to rotate, the limiter is driven by the spiral positioner to reciprocate up and down, and the limiter drives the scraper disc to reciprocate up and down, thereby continuously scraping the material sticking to the inner wall of the stirring kettle body when the mixer is stirring.

[0024] The present invention aims to address the shortcomings of existing storage tank technology and provide a foam concrete mixing tank, which is specifically achieved by the following technical solutions: Reference Figure 1 、 Figure 2 、 Figure 3 The present embodiment provides a foam concrete mixing tank, comprising a mixing tank body 1 and a stirring assembly 2. The stirring assembly 2 is disposed on a support of the mixer and is detachably connected to the mixing tank body 1. That is, the stirring assembly 2 is disposed on a support of an ordinary mixer, which has higher versatility. The stirring assembly 2 is provided with a motor 21, which is a motor used in an ordinary mixer. A stirring fan 22 is fixedly connected to an output end of the motor 21. The stirring fan 22 is driven by the motor 21 to rotate, thereby stirring the foam concrete in the mixing tank body 1.

[0025] Reference Figure 3Volume scale lines 13 are engraved on the inner wall of the mixing kettle body 1. A fan handle 221 at the top of the stirring fan 22 is connected to the motor 21 and is provided with a screw positioner 2211. The screw positioner 2211 is provided with a guide rail, with one side of the guide rail bottom being higher than the other. A transition slope is provided between the two sides, and the screw positioner 2211 rotates along with the fan handle 221. The limiter 242 is connected to two upper and lower limit wheels by bolts, wherein the upper limit wheel 2421 is arranged on the upper surface of the protruding guide rail on the spiral positioner 2211, and the lower limit wheel 2422 is arranged below the vertical position of the upper limit wheel 2421, and its upper surface is close to the lower surface of the protruding guide rail on the spiral positioner 2211. The height of the limiter 242 will change with the position of the guide rail on the spiral positioner 2211 at which it is located. Because the guide rail on the spiral positioner 2211 is a continuous circle structure, the height of the limiter 242 will reciprocate from the highest to the lowest, and then from the lowest to the highest.

[0026] Reference Figure 3 The control rod 241 is fixedly connected to the limiter 242, and the control rod 241 moves back and forth in the vertical direction following the limiter 242, thereby driving the scraper disc 24 to move up and down. The lower end of the control rod 241 is fixedly connected to the scraper disc 24, and the outer ring of the scraper disc 24 is in close contact with the inner wall of the mixing kettle body 1. When the stirring fan 22 rotates and stirs, the scraper disc 24 moves back and forth at the same time, scraping the material sticking to the inner wall of the mixing kettle body 1, thereby preventing foam and other materials from remaining on the inner wall of the mixing kettle body 1 and affecting the preparation effect of the foamed concrete.

[0027] Reference Figure 3 、 Figure 6 The scraper disc 24 is provided with a disc feeding hole 2411, which passes through the scraper disc 24. The scraper disc 24 is made of a transparent material. The outer edge of the scraper disc 24 is glued with rubber, and the outer edge of the scraper disc 24 is close to the inner wall of the stirring kettle body 1. The rubber can fit the inner wall of the stirring kettle body 1 more closely to ensure that there is no residue on the inner wall of the stirring kettle body 1 after hanging the material.

[0028] When the device is running, foam concrete can be directly added into it through the disc feeding hole 2411. The foam concrete is made of other external machines and can be directly output through a pipe. The pipe is directly connected to the disc feeding hole 2411 to complete the feeding work. The scraper disc 24 is made of transparent material. When adding material, the volume scale line 13 engraved on the inner wall of the mixing tank body 1 can be used to judge the feeding volume to ensure accurate feeding. If the foam concrete in the mixing tank body 1 needs to be filled to a certain volume, it is only necessary to control the speed of the motor 21. When the scraper disc 24 reciprocates up and down, after it moves to the corresponding position, the motor 21 is stopped, and the scraper disc 24 can be limited to the corresponding position. At this time, the external foam concrete is input into the mixing tank body 1 through the pipe and is added until it is full. The foam concrete can be accurately added to the volume marked on the volume scale line 13 at the horizontal position of the scraper disc 24 at this time.

[0029] Reference Figure 3 、 Figure 4 、 Figure 5 The first and second positioning plates 231 and 232 are respectively fixedly connected to the connecting rod 233 at one end and the other end of the first positioning plate 231 and the second positioning plate 232 at the same vertical position. The screw positioner 2211 is arranged between the first positioning plate 231 and the second positioning plate 232. The parts of the control rod 241 located at the upper and lower ends of the screw positioner 2211 respectively pass through the through holes provided on the first positioning plate 231 and the second positioning plate 232. This design can ensure that the limiter 242 is in close contact with the screw positioner 2211. Even if a certain degree of deviation occurs, the upper and lower ends of the control rod 241 are restricted in the through holes on the first positioning plate 231 and the second positioning plate 232, and cannot be separated from the screw positioner 2211, thereby ensuring the stability of the device during operation.

[0030] Reference Figure 3 The mixing fan 22 also includes a fan blade 222, which is arranged at the lower end of the fan handle 221. A horizontal straight rod is provided at the top of the fan blade 222, and can contact the lower surface of the scraping disc 24 when the scraping disc 24 moves to the lowest position, scraping the residual foam concrete on it onto the mixing fan 22, and through the rotation of the mixing fan 22, it is brought into the mixing kettle body 1 below.

[0031] Reference Figure 3The fan blade 222 is provided with a plurality of inclined rods. The fan blade 222 is a fan-shaped structure, which is an integrated structure welded by a plurality of rows of inclined rods and a vertical rod. The density of the inclined rods of the fan blade can be adjusted according to the needs of the specific situation. The distance between the outermost side of the fan blade 222 and the inner wall of the stirring tank body is 8~10 mm.

[0032] Reference Figure 1 、 Figure 2 The lower part of the mixing kettle body 1 is provided with a spiral base 14, which can be installed on the bracket of an ordinary mortar mixer. It has high adaptability and can adapt to most mortar mixers on the market, thereby improving the utilization rate of the equipment.

[0033] Reference Figure 3 The motor 21 is a driving motor on an ordinary mortar mixer, that is, all components connected to the motor 21 can be connected to the ordinary mortar mixer through the motor 21, and the stirring fan 22, the spiral positioner 2211, the limiting bracket 23, the scraper disc, and the control rod are all connected to the ordinary mortar mixer.

[0034] Reference Figure 1 、 Figure 2 A feeding port 11 penetrating the mixing kettle body 1 is fixedly installed on one side of the mixing kettle body 1, a pair of arc-shaped ears 12 are installed on both sides of the mixing kettle body 1, and a volume scale line 13 is provided on the inner wall. The volume scale line 13 and the feeding port 11 are provided on the mixing kettle body. During the foam concrete test preparation, the feeding port 11 can directly pump the prepared foam through the feeding port. By observing the volume scale line 13, the required foam volume can be controlled, thereby avoiding inaccurate foam volume added during the preparation process, affecting the preparation effect of the foam concrete, and the arc-shaped ears 12 are convenient for transportation.
