Abstract

This invention relates to the field of anti-corrosion concrete technology, and more particularly to a device for preparing energy-saving anti-corrosion concrete. The device includes a drive structure, three material box structures, and three material guiding structures. A transmission belt drives the first, second, and third meshing structures to rotate. The small, medium, and large gears have the same linear velocity in their meshing areas with the transmission belt. Due to the different gear diameters, they generate different rotational angular velocities. Slides located at the front, rear, and right ends are lifted by a screw rotating spirally. Within the same time frame, the lifting heights of the slides at the front, rear, and right ends are different, and the sizes of the cavities formed between the wall boxes and the square plates at the front, rear, and right ends are different. Through the above-mentioned configuration, this invention can pre-set cavities of different volumes for various materials used in the preparation of energy-saving and waste-utilizing anti-corrosion concrete, and is suitable for pre-treatment and storage of various materials with different required volumes before mixing and preparation.

Technical Field

[0001] This invention relates to the field of anti-corrosion concrete technology, specifically to an energy-saving anti-corrosion concrete preparation apparatus. Background Technology

[0002] The concrete preparation process consumes a large amount of energy through the firing of concrete in coal-fired furnaces. To improve the energy conservation and emission reduction efficiency of the concrete manufacturing industry, some concrete blocks from abandoned buildings can be crushed and recycled. By adding fiber powder, coal ash, and binder, they can be used to prepare the base material for energy-saving and corrosion-resistant concrete, thereby improving the recycling rate of waste concrete.

[0003] In the preparation of some energy-saving and corrosion-resistant concretes, the volumes of raw materials required for the preparation of the corrosion-resistant concrete base material are different. Existing methods for preparing energy-saving and corrosion-resistant concretes make it difficult to pre-treat and store the multiple materials required for mixing and preparation, which makes it inconvenient to feed the raw materials and results in low efficiency in mixing multiple materials. Therefore, an energy-saving and corrosion-resistant concrete preparation device is proposed to address the above problems. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the transmission belt drives the first meshing structure, the second meshing structure, and the third meshing structure to rotate. The small gear, the medium gear, and the large gear have the same linear velocity in the meshing area with the transmission belt. Due to the different gear diameters, they will generate different rotational angular velocities. The strip plate, vertical shaft, arc plate, screw, and second barrier plate are integrated structures. The sliding plates located at the front end, rear end, and right end are lifted by the screw through spiral rotation. In the same time, the lifting height of the sliding plates located at the front end, rear end, and right end is different. The sleeve, limit rod, and spring play an auxiliary role in vertical limiting.

In this invention, the second electrically controlled butterfly valve is opened and the first electrically controlled butterfly valve is closed. Then, the stepper motor reverses and starts, and the air pump device starts to pressurize the inside of the screen cylinder through the air supply pipe. The material in the cavity area formed between the wall box and the square plate is discharged through the conduit. The pressurized air is sprayed out through the fiber filter screen fixed inside the screen cylinder, forming a pressurized space between the wall box and the square plate to promote the discharge of the material. The material enters the trapezoidal block and the spray cover through the conduit and is sprayed out through the round hole set in the spray cover. Through the above configuration, a powder mixing and spraying structure for the preparation of various energy-saving and waste-utilizing anti-corrosion concrete is provided.

In this invention, the rotation drive and transmission drive of the main body of the device are both individually set stepper motors, and the linkage control of the main body of the device is strong. The sprayed material is mixed and stirred under the rotation of the transmission shaft structure. The mixed material is mixed and conveyed downward along the spiral surface of the first spiral plate. The mixed material is dispersed by the rotation of the handle and then mixed and conveyed downward through the spiral surface of the second spiral plate. Finally, the material is discharged downward through the gap of the discharge fan frame, which can further improve the mixing and stirring effect of the mixed material. Attached Figure Description

[0020] The internal threaded hole inside the slide plate 206 is threaded to rotate with the screw 117, and the through hole inside the slide plate 206 is slidably connected to the column 112.

The suction end pipe of the external powder conveying pump is connected to the silo, and the discharge end pipe of the external powder conveying pump is connected to the top of the flexible corrugated pipe 216, which facilitates the extraction and feeding of raw materials.

[0023] The top end of the conduit 31 is fixedly connected to the bottom end of the bottom frame 212. The inner wall of the cylinder 161 is fixedly installed with the conduit 31. The inner wall of the bottom frame 212 is inclined to facilitate downward material conveying. With the above configuration, the conduit 31, as a material conveying pipe, has the characteristic of facilitating pressurized material conveying.

[0024] The bottom of the stepper motor 17 housing is fixedly mounted to the top of the cylinder 161. The output end of the stepper motor 17 is fixedly connected to the drive gear 18, which meshes with the driven gear 192.

The inner wall of the cylinder 161 is in close contact with the first spiral plate 195, the handle 196, the second spiral plate 197, and the discharge fan frame 198. With the above arrangement, the rotation drive component and the transmission drive component of the main body of the device are both individually mounted stepper motors 17, so the linkage control of the main body of the device is strong.

[0025] like Figure 8 , Figure 9 as well as Figure 10 As shown, after the card plate 111 and the two cover plates 119 are assembled with external studs, they form an inner cavity space that limits the rotation of the strip plate 114 and the vertical shaft 115. Therefore, driven by the transmission belt 12, the strip plate 114, the vertical shaft 115, the arc plate 116, the screw 117 and the second barrier plate 118 are driven to rotate synchronously through the meshing rotation of the correspondingly meshing small gear 131, medium gear 141 and large gear 151.

[0026] Work process: The stepper motor 17, the first electrically controlled butterfly valve 215, the second electrically controlled butterfly valve 32, the air pump device 34, and the external powder conveying pump fixedly connected to the top of the flexible bellows 216 in this invention are all controlled by a PLC controller, and the above electrical devices are all connected to an external power supply.

[0027] like Figure 1 The diagram shows the initial state of the device. The horizontal height of the sliding plates 206 located at the front, rear, and right ends is the same. Taking the sliding plate 206 located at the front end as an example, as shown... Figure 28 , Figure 29 As shown, the bottom end of the slide plate 206 abuts against the top end of the arc plate 116 for a limiting position. At this time, the horizontal height of the square plate 202 located at the front end, rear end and right end inside the wall box 201 is the same. The stepper motor 17 starts to rotate in the forward direction, driving the drive gear 18 to rotate. Since the drive gear 18 is meshed with the driven gear 192, the shaft 191 can be driven to rotate through the driven gear 192. Since the shaft 191 and the inner ring of the ball bearing 163 are assembled through an external key block, the transmission shaft structure 19 rotates as a whole. The inner tooth groove of the transmission belt 12 of this device is meshed with the small gear 131, the medium gear 141, the large gear 151 and the flat gear 193. The transmission belt 12 is in contact with the first gear cover plate 132, the second gear cover plate 142, the third gear cover plate 152 and the fourth gear cover plate 194, which can prevent the transmission belt 12 from falling off due to up and down shaking during gear meshing transmission.

[0028] The transmission belt 12 drives the first meshing structure 13, the second meshing structure 14, and the third meshing structure 15 to rotate. The pinion 131, the intermediate gear 141, and the large gear 151 have the same linear velocity in the meshing area with the transmission belt 12, but these gears will generate different rotational angular velocities. The strip 114, the vertical shaft 115, the arc plate 116, the screw 117, and the second barrier plate 118 are an integrated structure. The sliding plates 206 located at the front, rear, and right ends are lifted by the screw 117 through spiral rotation. Figure 2 As shown, within the same time period, the lifting height of the sliding plate 206 set at the front end, rear end and right end is different, and the size of the cavity formed between the wall box 201 set at the front end, rear end and right end and the square plate 202 is different. The sleeve 209, the limiting rod 210 and the spring 211 play an auxiliary role in vertical limiting.

[0029] The quantitatively proportioned materials are placed inside multiple external silos. The suction end pipe of the external powder conveying pump is connected to the silo, and the discharge end pipe of the external powder conveying pump is connected to the top of the flexible corrugated pipe 216. The valve port of the second electrically controlled butterfly valve 32 is closed, and the valve port of the first electrically controlled butterfly valve 215 is opened. The external powder conveying pump, which is fixedly connected to the top of the flexible corrugated pipe 216, is started to fill the cavity area formed between the wall box 201 and the square plate 202 with materials. The cavity area formed between the wall box 201 and the square plate 202 at the rear end is the largest and is filled with energy-saving and waste-utilizing recycled and crushed concrete powder. The cavity area formed between the wall box 201 and the square plate 202 at the front end is the smallest and is filled with crushed fiber powder. The cavity area formed between the wall box 201 and the square plate 202 at the right end is of medium size and is filled with a mixture of coal ash and binder powder. The quantitatively proportioned materials can be pre-stored between the wall box 201 and the square plate 202.

[0030] The second electrically controlled butterfly valve 32 opens, the first electrically controlled butterfly valve 215 closes, and then the stepper motor 17 reverses and starts. The air pump device 34 starts and pressurizes the screen cylinder 36 through the air supply pipe 35. The material in the cavity area formed between the wall box 201 and the square plate 202 is discharged through the guide pipe 31. The pressurized air is sprayed out through the fiber filter screen fixedly installed inside the screen cylinder 36, forming a pressurized space between the wall box 201 and the square plate 202 to promote the discharge of the material. The material enters the internal cavity of the trapezoidal block 37 through the guide pipe 31 and is sprayed out through the round hole set in the spray cover 38 which is connected to the internal cavity of the trapezoidal block 37.

[0031] like Figure 1 , Figure 2 , Figure 26 As shown, the bottom of the discharge fan frame 198 is equipped with a transmission pulley device for conveying materials. Since the spray covers 38 are distributed at the front, rear, and right ends of the cylinder 161, the sprayed materials are mixed and agitated under the rotation of the transmission shaft structure 19. The mixture is conveyed downward along the spiral surface of the first spiral plate 195. The mixture is dispersed by the rotation of the handle 196 and conveyed downward along the spiral surface of the second spiral plate 197. Finally, it is discharged downward through the gaps in the discharge fan frame 198. The mixed concrete material can be used as a high-quality concrete filler base material, specifically as follows. Figure 1 , Figure 2 As shown, a drive pulley device is provided at the bottom of the mixing cylinder 16. The mixed concrete material at the gap of the discharge fan frame 198 falls into the top conveyor belt of the drive pulley device and can be transported to the next drying and storage process.
