Description

Technical Field

[0001] The invention relates to the technical field of building material processing, in particular to an anti-seepage filling material processing device and a method for the same for building engineering. Background Art

[0002] There are various kinds of anti-seepage filling materials for construction projects. Anti-seepage filling materials refer to materials that have the function of preventing the penetration of media such as water and oil. They are widely used in various projects that require waterproofing, moisture-proofing, and anti-seepage. Commonly used anti-seepage filling materials include bentonite anti-seepage materials, such as bentonite perlite, which has the characteristics of strong adsorption and low permeability, and can effectively prevent the penetration between soil and groundwater. The perlite raw material will be rapidly heated and expanded to 10-30 times its original volume when exposed to a high temperature flame of 1100-1200℃. The expanded perlite particles are white or light gray, with a honeycomb structure inside, and the loose density is generally 40-80Kg / m 3 .

[0003] However, because the water content of the raw material of perlite is generally 4-6%, due to the high water content, after high temperature heating, the rapid volatilization of water will cause the perlite to burst. Therefore, the invalid water content of the perlite should be removed before expansion, so that it retains the water required for normal expansion (i.e., effective water). Therefore, it needs to be preheated and evaporated during processing, otherwise the perlite directly expanded and overheated is easy to break, affecting the quality; therefore, it does not meet the existing needs, and we propose a processing equipment and method for anti-seepage filling materials for construction engineering. Summary of the invention

[0004] The present invention provides an anti-seepage filling material processing equipment and method for construction engineering, which has the advantages of preheating perlite and improving the heat treatment effect of perlite particles during preheating as much as possible, thereby shortening the preheating time and improving the processing efficiency. It solves the problem that the water content of the raw material ore of perlite mentioned in the above background technology is generally 4-6%. Due to the excessively high water content, the rapid volatilization of water after high-temperature heating will cause the perlite to burst. Therefore, the invalid water content of the perlite should be removed before expansion so that it retains the water required for normal expansion (i.e., effective water). Therefore, it needs to be preheated and evaporated during processing, otherwise the perlite directly expanded and overheated is easy to break, affecting the quality.

[0012] When the heat transfer hole at the bottom side rotates to the area of the long-diameter arc portion, the movable column moves downward under the action of gravity, the ball is in contact with the inner wall of the long-diameter arc portion, and a gap appears between the movable column and the heat transfer hole.

[0017] When the track connecting rod is located in the first sliding groove, the output shaft slows down, and at this time the movable plate retracts into the throwing plate, and the hollow portion is unobstructed.

[0018] A processing method for anti-seepage filling materials in construction engineering, comprising the following specific steps:

[0019] S1. Raw material selection: Select high-quality perlite raw materials, and process them into ore sand particles with particle size gradation through mechanical crushing and vibratory screening.

[0020] S2. Preheating treatment: Batch the particles according to their particle sizes and put them into a heat treatment cylinder for heat treatment until the effective moisture content of the perlite particles is between 2.2% and 2.4%.

[0021] S3. Expansion overheating: Evenly sprinkle the preheated perlite particles onto a flame with a temperature maintained at 1100 - 1200 °C to achieve the expansion of perlite.

[0022] S4. Separation and collection: After the expanded perlite is separated from the material through a cyclone separator along with the high-temperature gas, it enters the aggregate bin to achieve the preservation of expanded perlite.

[0023] The present invention has the following beneficial effects:

[0024] 1. The processing equipment and method for anti-seepage filling materials in construction engineering remove the ineffective moisture of perlite particles through the heat of a hot air blower in the heat treatment cylinder. The material in the heat treatment cylinder is continuously tossed and turned by the rotation of the turning device, so that the originally static or slowly moving perlite particles are in a continuous moving state. This movement helps the material to be evenly distributed in the heat treatment cylinder, improves the heating effect of perlite particles, enhances the heat treatment effect of perlite particles, shortens the preheating time, and improves the processing efficiency of anti-seepage filling materials in construction engineering. Different from the traditional technology, with the setting of the driving cone and the transmission cone in this equipment, when the driving motor rotates, due to the meshing relationship between the spiral protrusions and the spiral grooves, the rotation of the transmission cone is no longer simply uniform. When the spiral protrusions move along the spiral grooves, due to the curvature change of the grooves, the transmission cone will be pushed or resisted to varying degrees, resulting in a change in its rotation speed.

[0025] In this way, on the basis of tossing and turning the material, the output shaft rotates intermittently and variably, and finally transmits the variable rotation to the turning device, so that the turning device can rotate at a variable speed when performing work, suddenly accelerating when turning, thus achieving the effect of imitating manual turning and storing energy, increasing the movement potential energy of the material, making the perlite particles move farther, and further enhancing the preheating effect.

[0026] 2. The processing equipment and method for the anti-seepage filling material of the building project can better introduce hot air into the inner cylinder through the arrangement of heat transfer holes. Through the transmission between the direct output shaft and the output end cover, the inner cylinder rotates relative to the outer cylinder. Thus, when the equipment operates, the side wall of the inner cylinder constantly contacts the air outlet of the heat conduction channel, improving the uniform heating of the inner cylinder and further enhancing the heating effect of perlite particles.

[0027] Moreover, by movably arranging movable columns in the heat transfer holes, perlite with smaller particle size will not leak. Through the arrangement of the shaping cylinder and the long-diameter arc part, when the heat transfer hole rotates to the area of the long-diameter arc part, the movable columns move downward under gravity, the ball bearings fit with the inner wall of the long-diameter arc part, and a gap appears between the movable columns and the heat transfer holes, enabling hot air to flow upward. While preventing material leakage, it effectively ensures heat flow, improves heat balance, and further strengthens the preheating effect.

[0028] 3. The processing equipment and method for the anti-seepage filling material of the building project set a hollow part on the throwing plate, enabling the material to move farther when being thrown and flipped, and allowing heat to circulate more freely. Through the cooperation of the moving plate and the track groove, when the material falls, the moving plate hides and the hollow part is unobstructed. When the material needs to be collected and thrown, the moving plate blocks the hollow part, so that the throwing plate can hold the material and move it.

[0029] Moreover, when the track connecting rod is located in the second chute, the output shaft speed changes faster, and at this time, the moving plate blocks the hollow part.

[0030] When the track connecting rod is located in the first chute, the output shaft speed changes back to slow, and at this time, the moving plate retracts into the throwing plate and the hollow part is unobstructed. It is scientifically adapted to give full play to the cooperation effect of the mechanical structure as much as possible, further improving the heating effect of the filling material during preheating processing, shortening the processing time, and improving the processing effect.

Detailed implementation manners

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] In Embodiment 1, this embodiment aims to solve the problem that the water content of perlite raw ore sand is generally 4 - 6%. Due to the too high water content, after high-temperature heating, the rapid volatilization of water will cause the explosion of perlite. Therefore, the ineffective water content of perlite should be removed before expansion to retain the water required for normal expansion (i.e., effective water). Therefore, during processing, it is necessary to perform preheating and drying treatment on it. Otherwise, directly expanding and overheating processed perlite is prone to fragmentation, affecting the quality. Please refer to Figures 1 - 10, An anti-seepage filling material processing device for construction engineering, including a machine board 110 and a frame 140. A heat treatment cylinder 160 for preheating perlite and a hot air blower 170 for supplying hot air into the heat treatment cylinder 160 are installed on the frame 140. A turning device 190 for turning over perlite particles is rotatably installed in the heat treatment cylinder 160. A driving motor 120 for driving the turning device 190 to rotate is installed on the machine board 110. A driving cone 210 and a transmission cone 220 are rotatably installed on the driving motor 120. The driving cone 210 is coaxially arranged with the driving motor 120 and is driven by the driving motor 120. The setting direction of the transmission cone 220 is opposite to that of the driving cone 210. A spiral convex block 211 is arranged on the outer side of the driving cone 210, and a spiral groove 221 is arranged on the outer side of the transmission cone 220. The spiral convex block 211 meshes with the spiral groove 221. The transmission cone 220 is coaxially connected with an output shaft 130, and the output shaft 130 is connected with the turning device 190;

[0044] See Figure 3 , The driving cone 210 is driven by the driving motor 120 to rotate at a constant speed. The output shaft 130 undergoes intermittent variable-speed rotation due to the meshing of the spiral convex block 211 and the spiral groove 221, realizing that the turning device 190 imitates manual turning.

[0045] The heat treatment cylinder 160 includes an outer cylinder 330 fixedly arranged on the frame 140 for protection and heat preservation. A heat conduction channel 340 for conducting hot air is installed at the bottom of the outer cylinder 330. A hot air pipe 180 is connected between the heat conduction channel 340 and the hot air blower 170. An inner cylinder 310 is arranged inside the outer cylinder 330. A feeding end cover 350 for loading and unloading is installed on one side of the outer cylinder 330, and an output end cover 250 is installed on the other side of the outer cylinder 330. The turning device 190 is rotatably connected with the output end cover 250.

[0046] Specifically, several legs 150 are installed on the frame 140, and the legs 150 support the outer cylinder 330 to make it stable.

[0047] This embodiment also proposes a processing method for anti-seepage filling materials in construction engineering, including the following specific steps:

[0048] S1. Raw material selection, select high-quality perlite raw materials, and process them into sand particles with particle size gradation through mechanical crushing and vibrating screening;

[0049] S2. Preheat treatment, batch the particles according to the particle size and put them into the heat treatment cylinder 160 for heat treatment until the effective moisture content of the perlite particles is between 2.2 - 2.4%;

[0050] S3. Expansion overheating, evenly sprinkle the preheated perlite particles onto a flame with a temperature maintained at 1100 - 1200 °C to realize the expansion of perlite;

[0051] The perlite will be heated rapidly and expand rapidly to 10-30 times of its original volume. The expanded perlite particles are white or light gray, with a honeycomb structure inside, and the loose density is generally 40-80Kg / m 3 .

[0052] S4, separation and collection, the expanded perlite is separated by a cyclone separator along with the high-temperature gas and then enters a collection bin to achieve the preservation of the expanded perlite.

[0053] In this embodiment, the heat of the hot air blower 170 is used to remove the ineffective moisture of the perlite particles in the heat treatment cylinder 160, and the material in the heat treatment cylinder 160 is continuously flipped by the rotation of the material flipper 190, so that the originally stationary or slowly moving perlite particles are in a continuous moving state. This movement not only helps the material to be evenly distributed in the heat treatment cylinder 160, but more importantly, when the material is thrown into the air, the contact area between its surface area and the hot air is significantly increased, and the contact time is also extended, thereby improving the heating effect of the perlite particles and improving the thermal conductivity of the perlite particles. The processing effect is improved, and the preheating time is shortened to improve the processing efficiency of the anti-seepage filling material of the construction project; different from the traditional technology, the device is provided with the driving cone 210 and the transmission cone 220. When the driving motor 120 rotates, due to the meshing relationship between the spiral protrusion 211 and the spiral groove 221, the rotation of the transmission cone 220 is no longer a simple uniform speed. When the spiral protrusion 211 moves along the spiral groove 221, due to the change in the curvature of the groove, the transmission cone 220 will be pushed or resisted to varying degrees, thereby causing its rotation speed to change;

[0054] In this way, on the basis of flipping the material, the output shaft 130 is intermittently rotated at variable speeds, and the variable speed rotation is finally transmitted to the material turner 190, so that the material turner 190 can operate at a variable speed when performing work, and suddenly accelerate when turning, thereby achieving the effect of imitating artificial turning and accumulating force, thereby increasing the potential energy of material movement, allowing the perlite particles to move farther, and further enhancing the preheating effect.

[0055] Embodiment 2: This embodiment is intended to promote the solution of the problem of strengthening the hot air flow but preventing material leakage. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 - 10 A plurality of heat transfer holes 311 are provided in the middle of the inner cylinder 310. The inner cylinder 310 is installed with the output end cover 250. The driving cone 210 is coaxially connected with the straight-out shaft 230. The straight-out shaft 230 passes through the frame 140. A transmission belt 240 is installed on the straight-out shaft 230 and the output end cover 250. When the driving cone 210 rotates, the output shaft 130 and the inner cylinder 310 rotate simultaneously.

[0056] See Figure 7 , the heat transfer holes 311 are arranged as trumpet-shaped holes with a smaller inner diameter and a larger outer diameter. An active column 312 is movably installed in the heat transfer holes 311. The active column 312 is arranged as a cylinder, and the top diameter of the active column 312 is the same as the inner diameter of the heat transfer holes 311. A shaping cylinder 320 for controlling the movement of the active column 312 is arranged between the inner cylinder 310 and the outer cylinder 330.

[0057] The shaping cylinder 320 is connected to the outer cylinder 330. A long-diameter arc portion 321 is arranged at the bottom of the shaping cylinder 320. The long-diameter arc portion 321 is concentric with the shaping cylinder 320 and has a larger diameter than the shaping cylinder 320. Notches are arranged on both sides of the shaping cylinder 320 adjacent to the long-diameter arc portion 321, so that the hot air for the heat conduction channel 340 can enter the shaping cylinder 320.

[0058] A ball 313 for reducing frictional resistance is installed at the bottom of the active column 312. The ball 313 is intermittently attached to the inner wall of the long-diameter arc portion 321. When the heat transfer hole 311 rotates to be attached to the inner side of the shaping cylinder 320, the active column 312 is pushed by the inner wall of the shaping cylinder 320, so that the active column 312 in the heat transfer hole 311 is blocked.

[0059] When the heat transfer hole 311 at the bottom side rotates to the area of the long-diameter arc portion 321, the active column 312 moves downward under the action of gravity, the ball 313 is attached to the inner wall of the long-diameter arc portion 321, and a gap appears between the active column 312 and the heat transfer hole 311.

[0060] In this embodiment: through the arrangement of the heat transfer holes 311, the hot air can be better introduced into the inner cylinder 310. Through the transmission between the direct output shaft 230 and the output end cover 250, the inner cylinder 310 rotates relative to the outer cylinder 330. Therefore, when the device operates, the side wall of the inner cylinder 310 constantly contacts the air outlet of the heat conduction channel 340, improving the even heating of the inner cylinder 310 and further improving the heating effect of the perlite particles.

[0061] Moreover, by movably arranging the active column 312 in the heat transfer hole 311, the perlite with a smaller particle size will not leak. Through the arrangement of the shaping cylinder 320 and the long-diameter arc portion 321, when the heat transfer hole 311 rotates to the area of the long-diameter arc portion 321, the active column 312 moves downward under the action of gravity, the ball 313 is attached to the inner wall of the long-diameter arc portion 321, and a gap appears between the active column 312 and the heat transfer hole 311, so that the hot air can flow upward. While preventing the leakage of materials, the heat flow is effectively guaranteed, the heat balance is improved, and the preheating effect is further enhanced.

[0062] Embodiment 3. The purpose of this embodiment is to promote the solution to the problem of improving the material throwing and turning effect. This embodiment is an improvement based on Embodiment 2. Specifically, please refer to Figures 1 - 10, the material turning device 190 includes a throwing shaft 410 connected to the output shaft 130. A number of throwing plates 420 are circumferentially arrayed on the throwing shaft 410. The end of the throwing plate 420 is in sliding fit with the inner wall of the inner cylinder 310. A hollow portion 430 is provided in the middle of the throwing plate 420 for heat flow and the movement of perlite.

[0063] A moving plate 440 is slidably installed on the throwing plate 420 for intermittently blocking the hollow portion 430. A track groove 500 for guiding the movement of the moving plate 440 is provided on the inner wall of the output end cover 250.

[0064] The track groove 500 includes a first chute 510 and a second chute 520. The first chute 510 and the second chute 520 are concentric arc chutes. The diameter of the first chute 510 is smaller than that of the second chute 520. The first chute 510 and the second chute 520 are chamfer-connected. A track connecting rod 441 is connected to the side of the moving plate 440, and the track connecting rod 441 is engaged in the track groove 500;

[0065] When the track connecting rod 441 is located in the second chute 520, the output shaft 130 speeds up, and at this time the moving plate 440 blocks the hollow portion 430; when the track connecting rod 441 is located in the first chute 510, the output shaft 130 slows down, and at this time the moving plate 440 retracts into the throwing plate 420, and the hollow portion 430 is unobstructed.

[0066] It should be noted that the rotational speed of the output shaft 130 is faster than that of the inner cylinder 310.

[0067] In this embodiment: By providing the hollow portion 430 on the throwing plate 420, the material can move farther when being thrown and turned over, and the heat circulation is more free. Through the cooperation of the moving plate 440 and the track groove 500, when the material falls, the moving plate 440 is hidden and the hollow portion 430 is unobstructed. When the material needs to be collected and thrown and turned over, the moving plate 440 blocks the hollow portion 430, so that the throwing plate 420 can hold the material and move;

[0068] Moreover, when the track connecting rod 441 of this device is located in the second chute 520, the output shaft 130 speeds up, and at this time the moving plate 440 blocks the hollow portion 430;

[0069] When the track connecting rod 441 is located in the first chute 510, the output shaft 130 slows down, and at this time the moving plate 440 retracts into the throwing plate 420, and the hollow portion 430 is unobstructed. It is scientifically adapted to give full play to the cooperation effect of the mechanical structure as much as possible, further improving the heating effect of the filling material during preheating processing, shortening the processing time, and improving the processing effect.

[0070] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0071] The above are only the preferred embodiments of the present invention.
