Description

Technical Field

[0001] This utility model relates to a cleaning device for accumulating material on the inner wall of a slurry tank. Background Technology

[0002] Autoclaved aerated concrete (AAC) is a lightweight, porous silicate product made primarily from siliceous materials (sand, fly ash, and silica-containing tailings) and calcareous materials (lime and cement), with the addition of a foaming agent (aluminum powder). It is produced through processes including batching, mixing, pouring, pre-curing, cutting, autoclaving, and curing. It is named AAC because it contains a large number of uniform and fine pores after aeration.

[0003] The essential raw material for aerated concrete is siliceous material (sand, fly ash, and silicon-containing tailings, etc.). The processing of sand is illustrated by example: the sand is ground into a slurry by a ball mill and stored in a slurry tank. In the subsequent process, the slurry is pumped into a casting mixer, other materials are added, steam is introduced to heat it to a certain temperature, and then it is placed into a mold to generate gas and form a certain solid material.

[0004] Before pouring, the temperature of the slurry needs to meet the process requirements. However, since the slurry is stored in the tank for a long time, it is easy to dissipate heat, which will cause the temperature of the slurry to be lower than the pouring process requirements. Therefore, a heater is usually installed on the outer wall of the slurry tank to heat the slurry tank and keep the temperature of the slurry within the required process requirements range.

[0005] Because the heating device heats the slurry tank, the slurry tends to adhere to the inner wall of the slurry tank, forming a deposit layer. During use, this deposit layer increases the resistance to heat transfer, resulting in low efficiency or almost no heat transfer from the heater to the slurry. Consequently, the slurry cannot be heated, and its temperature cannot meet the requirements for aerated concrete preparation.

[0006] Currently, the accumulated material on the inner wall of the slurry tank is cleaned manually using tools (such as shovels). However, due to the large inner diameter of the slurry tank, the area of ​​the accumulated material layer that needs to be cleaned is large. Therefore, manual cleaning of the accumulated material on the inner wall of the slurry tank is not only time-consuming and labor-intensive, but also physically demanding. Utility Model Content

[0007] This invention provides a cleaning device for the accumulation of material on the inner wall of a slurry tank, which can automatically clean the accumulated material on the inner wall of the slurry tank.

[0008] A cleaning device for accumulating material on the inner wall of a slurry tank includes a slurry tank and a heating device, the heating device being disposed on the outer circumferential surface of the slurry tank, and further includes:

[0009] A drive mechanism that moves circumferentially along the slurry tank; the drive mechanism is in sync with the slurry tank.

[0010] A cleaning mechanism for cleaning up the accumulated material layer on the inner wall of a slurry tank. The cleaning mechanism is connected to a drive mechanism and moves circumferentially along with the drive mechanism.

[0011] Furthermore, the drive mechanism includes:

[0012] Support structure;

[0013] The first motor is mounted on the support.

[0014] A transmission mechanism, which is connected to the first motor;

[0015] The walking component is installed at least one end of the support body, the walking component is connected to the transmission mechanism, and the walking component is in conjunction with the slurry tank.

[0016] Furthermore, the drive mechanism also includes a column for positioning the support body, the column being located in the middle of the slurry tank, and the support body rotating in conjunction with the column; or

[0017] The drive mechanism also includes an inner connecting frame, an outer connecting frame, an inner guide wheel, and an outer guide wheel. The inner connecting frame is fixed to the support body, and the outer connecting frame is fixed to the support body or the drive mechanism. The inner guide wheel is connected to the inner connecting frame and rolls with the inner wall surface of the slurry tank, and the outer guide wheel is connected to the outer connecting frame and rolls with the outer wall surface of the slurry tank.

[0018] Furthermore, the support spans across the slurry tank, and walking components are installed at both ends of the support.

[0019] Furthermore, the cleaning mechanism is a flushing cleaning mechanism that sprays flushing media onto the accumulated material layer and / or a cutting cleaning mechanism that cuts the accumulated material layer.

[0020] Furthermore, the flushing cleaning mechanism includes a bracket, a rotary joint, a media supply assembly, a media conveying assembly, and a nozzle. The bracket is connected to the drive mechanism, the rotary joint is mounted on the bracket, one end of the rotary joint is connected to the media supply assembly, the other end of the rotary joint is connected to the media conveying assembly, and the media conveying assembly is connected to the nozzle.

[0021] Furthermore, there are multiple nozzles, and the media sprayed by these nozzles acts on the material accumulation layer in a sequence from high to low.

[0022] Furthermore, the cutting cleaning mechanism includes a connecting rod, a cutting component for cutting the accumulated material layer, the connecting rod being connected to a drive mechanism, the connecting rod being inserted into the slurry tank, and the cutting component being fixed to the connecting rod.

[0023] Furthermore, the cutting cleaning mechanism includes a second motor, which is connected to the drive mechanism;

[0024] A rotating frame driven to rotate by a second motor, the rotating frame being connected to the second motor;

[0025] A cutting component that cuts the accumulated material layer; the cutting component is connected to the rotating frame.

[0026] Furthermore, the cutting component is a scraper, a blade, a brush, or a cutter.

[0027] In this invention, the cleaning mechanism is mounted on the drive mechanism, allowing it to move circumferentially along the slurry tank. This continuous cleaning action removes or significantly reduces the thickness of the accumulated material layer on the inner wall of the slurry tank, minimizing resistance to heat transfer and ensuring efficient heating of the slurry within the tank, thus meeting the requirements for aerated concrete preparation. This invention enables cleaning both during slurry heating and after slurry discharge.

[0028] By using this invention, there is no need for manual cleaning inside the slurry tank, which not only reduces labor intensity, but also avoids the time-consuming nature of manual cleaning. Therefore, this invention does not affect the production rhythm and improves production efficiency compared to manual cleaning. Attached Figure Description

Detailed Implementation

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] Example 1

[0045] like Figures 1 to 4 The cleaning device for the slurry tank inner wall in this embodiment includes a slurry tank 1, a heating device A, a driving mechanism, and a cleaning mechanism. The following is a detailed description of each part and the relationship between them.

[0046] Heating device A is installed on the outer circumferential surface of slurry tank 1. The inner wall surface of slurry tank 1 corresponding to heating device A forms a material accumulation area B. Typically, a material accumulation layer that hinders heat transfer easily forms in accumulation area B. Heating device A can be a pipe wound spirally around slurry tank 1, or it can be a sleeve fitted onto slurry tank 1. The sleeve has a heat source inlet and outlet. The heat source can be steam, hot water, hot oil, etc. Waste heat or fresh steam is preferred. Using waste heat steam can utilize residual heat, save energy, and shorten the steam heating time of subsequent processes, thereby improving production efficiency. In this embodiment, heating device A is preferably a sleeve fitted onto slurry tank 1.

[0047] The drive mechanism moves circumferentially along the slurry tank 1 and cooperates with the slurry tank 1. The drive mechanism includes a support body 2, a first motor 3, a transmission mechanism 4, and a walking component C. The length of the support body 2 can be less than the outer diameter of the slurry tank 1. The support body 2 can also be a support beam or a support platform, etc. The length of the support body 2 can also be greater than the inner diameter of the slurry tank 1. In this embodiment, it is preferred that the length of the support body 2 can also be greater than the inner diameter of the slurry tank 1, so that the support body 2 spans across the top of the slurry tank 1. The walking component C is installed at at least one end of the support body 2. In this embodiment, the walking component C is installed at both ends of the support body 2.

[0048] The first motor 3 is mounted on the support body 2. The first motor 3 can be an electric motor, a hydraulic motor, etc. In this embodiment, the first motor 3 is preferably an electric motor. Since the entire drive mechanism moves continuously along the circumference of the slurry tank 1 during operation, in order to prevent the wires supplying power to the electric motor from getting tangled, in this embodiment, the electric motor is connected to a rotating slip ring 19. The rotating slip ring 19 is preferably a hollow rotating slip ring so that the medium supply component 12 in the cleaning mechanism can pass through. The rotating slip ring 19 is prior art and will not be described in detail here.

[0049] The transmission mechanism 4 is connected to the first motor 3, and the walking component C is connected to the transmission mechanism 4. The transmission mechanism 4 can be a sprocket and chain drive mechanism, a gear drive mechanism, or a belt drive mechanism. In this embodiment, the transmission mechanism 4 preferably adopts a sprocket and chain drive mechanism. The active sprocket is connected to the torque output end of the first motor 3, and the passive sprocket is connected to the walking component C. The chain is engaged with the active sprocket and the passive sprocket respectively.

[0050] The traveling component C is coupled with the slurry tank 1. The traveling component C can be a friction-driven traveling component or a gear-and-rack driven traveling component. Since the price of the gear-and-rack driven traveling component is relatively higher than that of the friction-driven traveling component, in this embodiment, the friction-driven traveling component C is preferred.

[0051] The walking component C includes a friction wheel C1, a friction plate C2, and a rotating shaft C3. The friction wheel C1 is fixed to the rotating shaft C3, and the rotating shaft C3 is rotatably connected to the support body 2, for example, through a bearing, so that the rotating shaft C3 can rotate relative to the support body 2. The passive sprocket in the transmission mechanism 4 is sleeved on the rotating shaft C3 and fixed to the rotating shaft C3. The friction plate C2 is fixed to the upper end of the slurry tank 1, and the friction wheel C1 cooperates with the friction plate C2.

[0052] If the walking component adopts a gear and rack structure, then the friction wheel C1 is replaced by a gear, and the friction plate C2 is replaced by a rack. The remaining connection relationships are the same as described above.

[0053] The drive mechanism also includes a column 5 for positioning the support body 2. The column 5 is located in the middle of the slurry tank 1. The support body 2 and the column 5 are rotatably coupled. Preferably, the column 5 is inserted into the slurry tank 1 and fixed to the bottom of the slurry tank 1 as a whole, so that the axis of the column 5 is on the same straight line as the axis of the slurry tank 1. When the support body 2 is driven by the first motor 3, the transmission mechanism 4 and the walking component C, the column 5 positions the middle of the support body 2, so the support body 2 rotates around the column 5 as the center of rotation. This provides both support and constraint for the support body 2, allowing the entire drive mechanism to move smoothly along the circumference of the slurry tank 1.

[0054] The cleaning mechanism cleans the accumulated material layer on the inner wall of the slurry tank 1. The cleaning mechanism is connected to the drive mechanism and moves circumferentially along the slurry tank 1 along with the drive mechanism. The cleaning mechanism is a flushing cleaning mechanism that sprays flushing medium onto the accumulated material layer and / or a cutting cleaning mechanism that cuts the accumulated material layer.

[0055] The flushing cleaning mechanism includes a bracket 10, a rotary joint 11, a media supply assembly 12, a media conveying assembly 13, and a nozzle 14. The bracket 10 is connected to the drive mechanism. The rotary joint 11 is mounted on the bracket 10. One end of the rotary joint 11 is connected to the media supply assembly 12, and the other end of the rotary joint 11 is connected to the media conveying assembly 13. The media conveying assembly 13 is connected to the nozzle 14.

[0056] The bracket 10 is fixed to the support body 2. The rotary joint 11 is existing technology. The rotary sliding ring 19 is located above the rotary joint 11 and is connected to the bracket 10. The media supply assembly 12 passes through the rotary sliding ring 19 and is connected to the rotary joint 11. The media supply assembly 12 consists of a delivery pump and a pipeline. The media supplied by the media supply assembly 12 can be a liquid or a mixture. The liquid can be water, and the mixture can be a mixture of water and sand. The media conveying assembly 13 is a pipeline. The support body 2 is provided with a support component 2a. The media conveying assembly 13 is installed on the support component 2a. The support component 2a consists of a support and a clamp. The media conveying assembly 13 passes through the clamp. The clamp is fixed to the support. The support is fixed to the support body 2. The support component 2a constrains the media conveying assembly 13 to prevent displacement of the media conveying assembly 13.

[0057] After being sprayed through nozzle 14, the medium acts on the accumulated material layer, scouring it and cleaning it. This reduces or completely removes the accumulated material layer, or significantly reduces its thickness, thereby improving the efficiency of heat transfer from heating device A to the slurry in slurry tank 1. The medium sprayed from nozzle 14 has a high pressure, for example, up to 4 MPa. In this embodiment, there are multiple nozzles 14, for example, six nozzles 14, and the medium sprayed from these nozzles acts on the accumulated material layer in a descending order. The gradient formed by the medium sprayed from nozzle 14 on the accumulated material layer makes it easier to disperse the accumulated material, thus improving the efficiency of cleaning the accumulated material.

[0058] In this embodiment, the slurry layer is flushed by a flushing medium. As the slurry in the slurry tank 1 is released, the slurry level drops, but the heating device A continues to work. When the slurry level drops below the highest point of the slurry layer, the flushing cleaning mechanism is activated. The medium sprayed by the flushing cleaning mechanism cleans the slurry layer. Therefore, the flushing cleaning mechanism is more effective when the slurry level drops below the highest point of the slurry layer.

[0059] Example 2

[0060] like Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that this embodiment does not use positioning pin 5. This embodiment uses the following structure to guide the drive mechanism, as detailed below:

[0061] The drive mechanism also includes an inner connecting frame 6, an outer connecting frame 7, an inner guide wheel 8, and an outer guide wheel 9. The inner connecting frame 6 is fixed to the support body 2, and the outer connecting frame 7 is fixed to the support body 2 or the drive mechanism. In this embodiment, the drive mechanism also includes a cover 20, and the outer connecting frame 7 is fixed to the cover 20. The inner connecting frame 6 is located inside the slurry tank 1, and the outer connecting frame 7 is located outside the slurry tank 1. The inner guide wheel 8 is connected to the inner connecting frame 6 and rolls with the inner wall surface of the slurry tank 1, and the outer guide wheel 9 is connected to the outer connecting frame 7 and rolls with the outer wall surface of the slurry tank 1. The inner guide wheel 8 and the outer guide wheel 9 clamp the slurry tank 1, thereby preventing the drive mechanism from moving radially along the slurry tank 1. Therefore, this structure provides radial positioning for the drive mechanism, and the inner guide wheel 8 and the outer guide wheel 9 guide the drive mechanism as it moves circumferentially along the slurry tank 1.

[0062] Example 3

[0063] like Figure 7The difference between this embodiment and Embodiment 1 is that the cleaning mechanism in this embodiment adopts a cutting cleaning mechanism. The cutting cleaning mechanism includes a connecting rod 15 and a cutting component 16 for cutting the accumulated material layer. The connecting rod 15 is connected to the drive mechanism and hinged to the support body 2. The connecting rod 15 is inserted into the slurry tank 1, and the cutting component 16 is fixed to the connecting rod 15. The cutting component 16 is a scraper, scraper blade, brush, or cutter. The connecting rod 15 moves along the circumference of the slurry tank 1 with the drive mechanism, and the cutting component 16 cuts the accumulated material layer, causing the accumulated material to fall into the slurry tank 1.

[0064] The cutting cleaning mechanism also includes a retaining component that keeps the cutting component 16 engaged with the material accumulation layer in the slurry tank 1. The retaining component includes a diagonal brace 21, one end of which is connected to the drive mechanism and the other end of which is connected to the connecting rod 15. In this embodiment, one end of the diagonal brace 21 is preferably connected to the support body 2.

[0065] The diagonal brace 21 and the support body 2 can be connected to the support body 2 and the connecting rod 15 respectively using turnbuckles. The diagonal brace 21 can also be composed of a connecting rod and a spring. One end of the connecting rod is connected to the support body 2, and the other end of the connecting rod is connected to one end of the spring. The other end of the spring is connected to the connecting rod 15. Under the action of the spring, the diagonal brace 21 is kept in contact with the inner wall of the material accumulation layer or the slurry tank 1. When the cutting part 16 is subjected to greater resistance, the connecting rod 15 swings, thereby avoiding the cutting accumulation and preventing damage to the cutting part 16.

[0066] The accumulated material layer can be cleaned using a cutting-type cleaning machine during the heating process of the slurry or after the slurry has been discharged.

[0067] During the slurry heating process, if the slurry level is higher than the height of the accumulation layer, the moisture in the slurry can replenish the accumulation layer, keeping it in a softer state. Therefore, cutting the accumulated layer in this situation will be more effective. As the slurry is released and the slurry level drops below the highest point of the accumulation layer, the heating device A continues heating, causing the accumulation layer to lose water and change its hardness. Although this increases the cutting resistance of the cutting cleaning mechanism, it still allows for cutting of the accumulation layer.

[0068] Example 4

[0069] like Figure 8 and Figure 9The difference between this embodiment and embodiment 1 is that the cleaning mechanism in this embodiment adopts a cutting cleaning mechanism. The cutting cleaning mechanism includes a cutting component 16, a second motor 17, and a rotating frame 18 driven by the second motor 17. The second motor 17 is connected to the drive mechanism and fixed to the support body 2. The rotating frame 18 is connected to the second motor 17. The cutting component 16 is connected to the rotating frame 18. The cutting component 16 cuts the accumulated material layer. The cutting component 16 is a scraper, scraper blade, brush or cutter.

[0070] When the second motor 17 operates, it drives the rotating frame 18 to rotate. The cutting component 16 mounted on the rotating frame 18 cuts the accumulated material layer. During rotation, the rotating frame 18 agitates the slurry in the slurry tank 1 to prevent material sedimentation and maintain the proper quality of the slurry. In this embodiment, the rotating frame 18 is positioned off-center from the slurry tank 1. While the entire cutting cleaning mechanism moves circumferentially around the slurry tank 1 under the action of the drive mechanism, the rotating frame 18 moves circumferentially around the center of the slurry tank 1, resulting in better agitation of the slurry.

[0071] Examples other than those described above:

[0072] The cleaning mechanism can also adopt a combination of Embodiment 1 and Embodiment 3 (e.g. Figure 10 ), or a combination of Embodiment 1 and Embodiment 4 (such as Figure 11 ), or a combination of Examples 3 and 4.

[0073] The combination of Embodiments 1 and 3 is a combination of a flushing cleaning mechanism and a cutting cleaning mechanism, and the combination of Embodiments 1 and 4 is also a combination of a flushing cleaning mechanism and a cutting cleaning mechanism. Considering that the hardness of the accumulated material layer changes after the slurry release level drops below the highest point of the accumulated material layer, flushing the accumulated material layer with a flushing cleaning mechanism and then cutting the accumulated material layer with a cutting cleaning mechanism can not only reduce cutting resistance but also significantly improve the cleaning effect. Therefore, the combination of a flushing cleaning mechanism and a cutting cleaning mechanism is the best implementation method.

[0074] Alternatively, an oscillating cleaning mechanism can be used for the cleaning mechanism. The oscillating cleaning mechanism includes a connecting rod 15 and a vibration generator mounted on the connecting rod 15. The vibration generator can be an ultrasonic generator. The power supply for the vibration generator can be led out from the rotating sliding ring 19 and connected to the vibration generator.

[0075] In addition, the length of the support body 2 can be less than the inner diameter of the slurry tank 1. One end of the support body 2 is equipped with a walking component C, and the other end of the support body 2 is rotatably engaged with the column 5.

[0076] like Figure 12As shown, the difference between this embodiment and embodiment 3 is that the retaining component includes a support plate 22 and an eccentric block 23. The support plate 22 is fixed to the connecting rod 15, and the eccentric block 23 is connected to the support plate 22. The support plate 22 provides support for the eccentric block 23. The center of gravity of the eccentric block 23 is offset from the center of the support plate 22, and the eccentric block 23 is far away from the connecting rod 15. The eccentric block 23 is close to the other end of the support plate 22. The weight of the eccentric block 23 and its installation position are used to keep the cutting component 16 in contact with the material accumulation layer in the slurry tank 1.
