Description

Technical Field

[0001] This utility model relates to the technical field of fine aggregate cooling equipment for concrete production, specifically a fine aggregate precooling device for concrete production. Background Technology

[0002] Concrete is a material made of cement, sand, water, admixtures, and additives in a certain proportion. It is widely used in construction engineering. Fine aggregate is an important component of concrete, and its main function is to fill the gaps between coarse aggregates, making the concrete denser. At the same time, it participates in the hydration reaction of cement, improving the workability and strength of concrete. In concrete production, fine aggregate pre-cooling devices are used to reduce the discharge temperature of concrete. This is because in a high-temperature environment, the internal hydration reaction of concrete accelerates, which can easily lead to quality problems such as cracks. Pre-cooling fine aggregate can effectively control the temperature of concrete, improve its performance and durability, and ensure the quality of the project.

[0003] In the prior art, patent publication number CN 214665486 U discloses a pre-cooling device for fine aggregate in concrete production, including four support rods, the tops of which are connected to a pre-cooling box. A cover plate is movably connected to one end of the pre-cooling box. An inlet is connected to one side of the top of the pre-cooling box. A material guiding and cooling device is interspersed inside the pre-cooling box. An outlet is connected to one side of the lower end of the pre-cooling box, and a sealing plate is provided at the lower end of the outlet. A cold air device is connected to the other side of the top of the pre-cooling box. This invention is easy to operate. The cold air device can be used in conjunction with the material guiding and cooling device, making the pre-cooling method for fine aggregate more diversified and the pre-cooling effect better. Simultaneously, operators can control the pre-cooling intensity of the fine aggregate, and the device can reduce the residual amount of fine aggregate during discharge, making the entire device more practical.

[0004] The aforementioned cable production and processing dryer has some problems in practical applications. Fine aggregates tend to accumulate on the feed chute, resulting in poor aggregate flow. The gaps between fine aggregates cannot be adjusted in time, and cold air or other cooling media cannot pass through the aggregate layer evenly, thus causing uneven cooling and affecting the quality stability of concrete. To address this, we propose a fine aggregate pre-cooling device for concrete production. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a fine aggregate precooling device for concrete production, which effectively improves the precooling efficiency and quality of fine aggregate, thereby improving the performance and quality stability of concrete, ensuring the smooth progress of concrete production and the reliability of product quality, and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-cooling device for fine aggregate in concrete production, comprising a cooling box, wherein guide grooves are respectively provided on the front and rear inner walls of the cooling box, and a vibration mechanism is also included.

[0007] Vibration mechanism: It includes guide rods, sliders, and springs. Guide rods are respectively provided between the upper and lower inner walls of the guide groove. Sliders are slidably connected inside the guide groove. The middle part of the slider is slidably connected to the outside of the guide rod inside the same guide groove. The inner upper surface of each of the four sliders is fixedly connected to the lower surface of a microporous mesh plate. The springs are movably sleeved on the outside of the guide rods. The springs are all located between the lower surface of the slider and the bottom wall of the guide groove. It effectively improves the pre-cooling efficiency and quality of fine aggregate, thereby improving the performance and quality stability of concrete, ensuring the smooth progress of concrete production and the reliability of product quality.

[0008] Furthermore, a microcontroller is provided on the front side of the cooling box. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical components.

[0009] Furthermore, the vibration mechanism also includes a support column, an adjusting rod, a slide groove, a rotating shaft, a drive rod, and a sliding rod. The front and rear inner walls of the cooling box are rotatably connected to the support column, and the outside of the support column is fixedly fitted with an adjusting rod. The top of the adjusting rod is provided with a slide groove. The front and rear inner walls of the cooling box are rotatably connected to the rotating shaft, and the outside of the rotating shaft is fixedly fitted with a drive rod. A sliding rod is rotatably connected between the two drive rods. The outside of the sliding rod is slidably connected to the inner wall of the slide groove. The top of the adjusting rod is fitted with the bottom of the microporous mesh plate to realize vibration.

[0010] Furthermore, a motor is provided on the rear side of the cooling box. The front end of the motor's output shaft is fixedly connected to the rear end of the rear support column, and the input end of the motor is electrically connected to the output end of the microcontroller to provide vibration drive.

[0011] Furthermore, the upper surface of the cooling box is provided with a feed inlet, and a trapezoidal feed trough is fixedly connected to the top of the feed inlet. The upper surface of the cooling box is provided with a discharge outlet, and a guide plate is fixedly connected to the bottom of the discharge outlet to facilitate feeding and discharging.

[0012] Furthermore, a condenser tube is provided on the left inner wall of the cooling box, and a water tank is provided on the rear side of the cooling box.

[0013] Furthermore, a fan is installed on the left side of the cooling box. The fan is installed in conjunction with the condenser pipe. The input end of the fan is electrically connected to the output end of the microcontroller to achieve uniform distribution of cold air inside.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This pre-cooling device for fine aggregate in concrete production has the following advantages:

[0015] The motor drives the rotating column to rotate, causing the drive rod to rotate and slide within the adjusting rod groove. This causes the adjusting rod to swing up and down under the support of the support column. The top of the adjusting rod indirectly contacts the microporous mesh plate. The spring continuously contracts and rebounds, causing the fine aggregate to tumble on the upper surface of the microporous mesh plate, fully contacting the cold air inside the cooling box. This pre-cooling of the fine aggregate prevents it from accumulating and clumping on the microporous mesh plate, ensuring smooth flow and allowing the gaps between the fine aggregates to constantly change. This allows the cold air or cooling medium to pass through the aggregate layer more evenly, ensuring uniform cooling of the fine aggregate. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a pre-cooling device for fine aggregate in concrete production, including a cooling box 1, with guide grooves 13 on the front and rear inner walls of the cooling box 1, and a vibration mechanism 6. A microcontroller 5 is provided on the front side of the cooling box 1, with its input terminal electrically connected to an external power source. A feed inlet is provided on the upper surface of the cooling box 1, with a trapezoidal feed trough 2 fixedly connected to the top of the feed inlet. A discharge outlet is provided on the upper surface of the cooling box 1, with a guide plate 3 fixedly connected to the bottom of the discharge outlet. A condenser pipe 8 is provided on the left inner wall of the cooling box 1, and a water tank 10 is provided on the rear side of the cooling box 1. The inlet and outlet of the condenser pipe 8 are both connected to the interior of the water tank 10 through a conveying pipe 9. A water pump 11 is connected in series in the middle of the conveying pipe 9 at the bottom, with its input terminal electrically connected to the output terminal of the microcontroller 5. A fan is provided on the left side of the cooling box 1. 12. The fan 12 and the condenser tube 8 are installed together. The input end of the fan 12 is electrically connected to the output end of the microcontroller 5. When the fine aggregate in concrete production needs to be pre-cooled, the cooling box 1 is placed in the designated position, and then the water tank 10 is filled with water. Then, through the control of the microcontroller 5, the fan 12 and the water pump 11 start to work. The water pump 11 will pump the cooling water into the condenser tube 8 through the delivery pipe 9. The cooling water will circulate inside the condenser tube 8 and cool the hot air in the cooling box 1 that is in contact with the condenser tube 8. The fan 12 will blow the cooled air into the cooling box 1. The hot air inside the cooling box 1 will be discharged through the two ventilation holes on the right side of the upper surface. Then, the pre-cooled fine aggregate is poured into the cooling box 1 through the trapezoidal feed chute 2 and falls on the upper end of the microporous mesh plate 4. The fine aggregate comes into contact with the cold air inside and is cooled.

[0023] Vibration mechanism 6: It includes guide rods 61, sliders 62, and springs 63. Guide rods 61 are respectively provided between the upper and lower inner walls of the guide groove 13. Sliders 62 are slidably connected inside the guide groove 13. The middle part of the slider 62 is slidably connected to the outside of the guide rod 61 inside the same guide groove 13. The inner upper surface of each of the four sliders 62 is fixedly connected to the lower surface of a microporous mesh plate 4. Springs 63 are movably sleeved on the outside of the guide rods 61. The springs 63 are all located between the lower surface of the slider 62 and the bottom wall of the guide groove 13. The vibration mechanism 6 also includes a support column 64, an adjusting rod 65, a slide groove 66, a rotating shaft 67, a drive rod 68, and a sliding rod 69. The support column 64 is rotatably connected to the front and rear inner walls of the cooling box 1, and the adjusting rod 65 is fixedly sleeved on the outside of the support column 64. The top of the adjusting rod 65 is provided with a slide groove 66. The rotating shaft 67 is rotatably connected to the front and rear inner walls of the cooling box 1, and the drive rod 68 is fixedly sleeved on the outside of the rotating shaft 67. A sliding rod 69 is rotatably connected between the two drive rods 68. The outside of the sliding rod 69 is flush with the inner wall of the slide groove 66. The sliding connection is used, with the top of the adjusting rod 65 fitting with the bottom of the microporous mesh plate 4. A motor 7 is located on the rear side of the cooling box 1. The front end of the output shaft of the motor 7 is fixedly connected to the rear end of the rear support column 64. The input end of the motor 7 is electrically connected to the output end of the microcontroller 5. Through the control of the microcontroller 5, the motor 7 starts running, and the output shaft drives the rear rotating column 67 to rotate. This causes the externally mounted drive rod 68 to drive the sliding rod 69 to rotate, allowing the sliding rod 69 to both rotate and slide within the sliding groove 66 at the top of the adjusting rod 65, thereby driving... The adjusting rod 65 swings up and down under the support of the support column 64. When the sliding rod 69 at the upper end of the drive rod 68 raises the adjusting rod 65, the microporous mesh plate 4 reaches its highest point and the spring 63 returns to its normal state. When the drive rod 68 rotates and the sliding rod 69 moves away from the microporous mesh plate 4, the microporous mesh plate 4 moves down under its own weight. With the high-speed rotation of the drive rod 68, the microporous mesh plate 4 vibrates under the rebound force of the spring 63, causing the fine aggregate to roll on the upper surface of the microporous mesh plate 4 and fully contact the cold air inside the cooling box 1 to achieve cooling.

[0024] The working principle of the pre-cooling device for fine aggregate in concrete production provided by this utility model is as follows: When the fine aggregate in concrete production needs to be pre-cooled, the cooling box 1 is placed in a designated position, and then the water tank 10 is filled with water. Then, through the control of the microcontroller 5, the fan 12 and water pump 11 start working. The water pump 11 draws cooling water into the condenser tube 8 through the delivery pipe 9. The cooling water circulates inside the condenser tube 8, exchanging heat with the hot air in contact with the condenser tube 8 inside the cooling box 1 to cool it down. The fan 12 blows the cooled air into the cooling box 1. The hot air inside the cooling box 1 is discharged through two ventilation holes on the right side of the upper surface. Then, the pre-cooled fine aggregate is poured into the cooling box 1 through the trapezoidal feed chute 2, falling onto the upper end of the microporous mesh plate 4. The fine aggregate comes into contact with the cold air inside for heat exchange. To cool down the material, the microcontroller 5 controls the motor 7 to start running. The output shaft drives the rear rotating column 67 to rotate, causing the externally mounted drive rod 68 to rotate the slide rod 69. The slide rod 69 rotates and slides inside the groove 66 at the top of the adjusting rod 65, which in turn causes the adjusting rod 65 to swing up and down under the support of the support column 64. When the slide rod 69 at the top of the drive rod 68 raises the adjusting rod 65, the spring 63 returns to its normal state at the highest point of the microporous mesh plate 4. When the drive rod 68 rotates and the slide rod 69 moves away from the microporous mesh plate 4, the microporous mesh plate 4 moves down under its own weight. With the high-speed rotation of the drive rod 68, the microporous mesh plate 4 vibrates under the rebound force of the spring 63, causing the fine aggregate to roll on the upper surface of the microporous mesh plate 4, making full contact with the cold air inside the cooling box 1, thus achieving cooling.

The microcontroller 5 controls the operation of the motor 7, the water pump 11 and the fan 12 using methods commonly used in the prior art.
