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

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.

[0017] When the track link is located in the first slide groove, the output shaft slows down, and at this time, the moving plate retracts into the ejection plate, and the hollow portion is unobstructed.

[0018] A method for processing an anti-seepage filling material for a construction project comprises 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 distribution through mechanical crushing and vibration screening;

[0020] S2, preheating treatment, putting the particles into the heat treatment cylinder in batches according to the particle size for heat treatment until the effective water content of the perlite particles is between 2.2-2.4%;

[0021] S3, expansion overheating, the preheated perlite particles are evenly sprinkled on the flame maintained at a high temperature of 1100-1200℃ to achieve the expansion of the perlite;

[0022] 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.

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

[0024] 1. The anti-seepage filling material processing equipment and method for construction projects use the heat of the hot air blower to remove the invalid moisture of the perlite particles in the heat treatment cylinder, and the material in the heat treatment cylinder is continuously flipped by the rotation of the material turner, so that the originally stationary or slowly moving perlite particles are in a continuous moving state. This movement helps to evenly distribute the material in the heat treatment cylinder, improve the heating effect of the perlite particles, improve the heat treatment effect of the perlite particles, shorten the preheating time, and improve the processing efficiency of the anti-seepage filling material for construction projects; different from the traditional technology, this equipment is through the setting of the driving cone and the transmission cone. When the driving motor rotates, due to the meshing relationship between the spiral protrusion and the spiral groove, the rotation of the transmission cone is no longer a simple uniform speed. When the spiral protrusion moves along the spiral groove, due to the change in the curvature of the groove, the transmission cone will be pushed or resisted to varying degrees, thereby causing its rotation speed to change;

[0025] In this way, on the basis of flipping the material, the output shaft undergoes intermittent speed-changing rotation, which is ultimately transmitted to the material turner, so that the material turner can operate at a variable speed when performing work, and suddenly accelerate when flipping, thereby achieving the effect of simulating artificial flipping and accumulating force, thereby increasing the potential energy of material movement, allowing the perlite particles to move farther, and further enhancing the preheating effect.

[0026] 2. The anti-seepage filling material processing equipment and method of the construction project can better guide the hot air into the inner cylinder through the arrangement of the heat transfer holes, and the inner cylinder rotates relative to the outer cylinder through the transmission of the straight-out shaft and the output end cover, so that when the equipment is running, the side wall of the inner cylinder keeps in contact with the air outlet of the heat conduction channel, thereby improving the heat balance of the inner cylinder and further improving the heating effect of the perlite particles;

[0027] Moreover, by movably setting a movable column in the heat transfer hole, the perlite with smaller particle size will not leak. By setting the shaping cylinder and the long-diameter arc portion, when the heat transfer hole rotates to the long-diameter arc portion area, the movable column moves downward due to gravity, and the ball fits against the inner wall of the long-diameter arc portion. A gap appears between the movable column and the heat transfer hole, so that the hot air can flow upward. While preventing material leakage, the heat flow is effectively guaranteed, the heat balance is improved, and the preheating effect is further enhanced.

[0028] 3. The anti-seepage filling material processing equipment and method of the construction project, by setting a hollow part on the throwing plate, can make the material move farther when thrown, and the heat flow more freely. Through the cooperation of the moving plate and the track groove, when the material falls, the moving plate is hidden 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;

[0029] Moreover, when the track connecting rod of the device is located in the second slide groove, the output shaft speeds up, and at this time the moving plate blocks the hollow part;

[0030] When the track connecting rod is located in the first slide groove, the output shaft changes speed slowly, and the moving plate retracts into the ejection plate. The hollow part is unobstructed and scientifically adapted to maximize the mechanical structure coordination effect, further improving the heating effect of the filling material during the preheating process, shortening the processing time and improving the processing effect.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example 1: This example aims to solve the problem that the water content of the raw material of perlite is generally 4-6%. Due to the 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 can retain 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. Please refer to Figure 1-Figure 10, a construction engineering anti-seepage filling material processing equipment, including a machine plate 110 and a frame 140, the frame 140 is equipped with a heat treatment cylinder 160 for preheating perlite and a hot air blower 170 for providing hot air in the heat treatment cylinder 160, a turner 190 for turning perlite particles is rotatably installed in the heat treatment cylinder 160, a driving motor 120 for driving the turner 190 to rotate is installed on the machine plate 110, and a driving cone is rotatably installed on the driving motor 120 210 and a transmission cone 220, the driving cone 210 is coaxially arranged with the driving motor 120 and driven by the driving motor 120, the transmission cone 220 is arranged in a direction opposite to the driving cone 210, a spiral protrusion 211 is arranged on the outside of the driving cone 210, a spiral groove 221 is arranged on the outside of the driving cone 220, the spiral protrusion 211 is meshed with the spiral groove 221, the transmission cone 220 is coaxially connected with the output shaft 130, and the output shaft 130 is connected to the tipper 190;

[0044] See Figure 3 The driving cone 210 is driven by the driving motor 120 to rotate at a constant speed, and the output shaft 130 rotates intermittently due to the engagement of the spiral protrusion 211 with the spiral groove 221, so that the material turner 190 imitates manual material 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 loading end cover 350 for loading and unloading is installed on one side of the outer cylinder 330. An output end cover 250 is installed on the other side of the outer cylinder 330. The turner 190 is rotatably connected to the output end cover 250.

[0046] In the specific configuration, a plurality of legs 150 are installed on the frame 140 , and the legs 150 prop up the outer cylinder 330 to stabilize it.

[0047] This embodiment also proposes a method for processing an anti-seepage filling material for a construction project, comprising the following specific steps:

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

[0049] S2, preheating treatment, the particles are put into the heat treatment cylinder 160 in batches according to the particle size for heat treatment until the effective water content of the perlite particles is between 2.2-2.4%;

[0050] S3, expansion overheating, the preheated perlite particles are evenly sprinkled on the flame maintained at a high temperature of 1100-1200℃ to achieve the expansion of the 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 Figure 1-Figure 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 hole 311 is set as a trumpet-shaped hole with a small inside and a large outside. A movable column 312 is movably installed in the heat transfer hole 311. The movable column 312 is set as a cylinder. The top diameter of the movable column 312 is the same as the inner diameter of the heat transfer hole 311. A shaping cylinder 320 for controlling the movement of the movable column 312 is set between the inner cylinder 310 and the outer cylinder 330.

[0057] The shaping cylinder 320 is connected to the outer cylinder 330, and a long-diameter arc portion 321 is arranged at the bottom of the shaping cylinder 320. The long-diameter arc portion 321 is arranged concentrically 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 hot air from the heat conduction channel 340 can enter the shaping cylinder 320.

[0058] A ball 313 for reducing friction resistance is installed at the bottom of the movable 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 fit the inner side of the shaping cylinder 320, the movable column 312 is pushed by the inner wall of the shaping cylinder 320, so that the movable column 312 in the heat transfer hole 311 is blocked;

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

[0060] In this embodiment: by setting the heat transfer hole 311, the hot air can be better introduced into the inner cylinder 310, and the inner cylinder 310 can rotate relative to the outer cylinder 330 through the transmission of the straight-out shaft 230 and the output end cover 250, so that when the equipment is running, the side wall of the inner cylinder 310 is constantly in contact with the air outlet of the heat conduction channel 340, so as to improve the heat balance of the inner cylinder 310 and further improve the heating effect of the perlite particles;

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

[0062] Embodiment 3: This embodiment is intended to promote the solution to the problem of improving the material flipping effect. This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-Figure 10The material turner 190 includes a material throwing shaft 410 connected to the output shaft 130, and a plurality of material throwing plates 420 are installed in a circumferential array on the material throwing shaft 410. The ends of the material throwing plates 420 are slidably fitted with the inner wall of the inner cylinder 310, and a hollow portion 430 is opened in the middle of the material throwing plate 420 for heat flow and movement of perlite.

[0063] A moving plate 440 is slidably mounted on the ejection plate 420 for intermittently blocking the hollow portion 430 , and 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 slide groove 510 and a second slide groove 520. The first slide groove 510 and the second slide groove 520 are configured as concentric arc slide grooves, and the diameter of the first slide groove 510 is smaller than the diameter of the second slide groove 520. The first slide groove 510 and the second slide groove 520 are connected by a chamfer. The side of the moving plate 440 is connected to a track link 441, and the track link 441 is engaged in the track groove 500.

[0065] When the track link 441 is located in the second slide groove 520, the output shaft 130 speeds up, and the movable plate 440 blocks the hollow portion 430; when the track link 441 is located in the first slide groove 510, the output shaft 130 speeds up, and the movable plate 440 retracts into the ejection plate 420, and the hollow portion 430 is unobstructed.

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

[0067] In this embodiment: by setting the hollow part 430 on the throwing plate 420, the material can move farther when thrown, and the heat can flow more freely. 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 part 430 is unobstructed. When the material needs to be collected and thrown, the moving plate 440 blocks the hollow part 430, so that the throwing plate 420 can hold the material and move;

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

[0069] When the track link 441 is located in the first slide groove 510, the output shaft 130 slows down, and the movable plate 440 retracts into the ejection plate 420. The hollow portion 430 is unobstructed and scientifically adapted to maximize the mechanical structure coordination effect, further improving the heating effect of the filling material during the preheating process, shortening the processing time, and improving the processing effect.

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

[0071] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
