Description
Technical Field
[0001] This utility model relates to the technical field of material drying, specifically a drying device for building materials. Background Technology
[0002] Sand and gravel are essential building materials in the construction process. If sand and gravel contain too much moisture, it will affect the accuracy of the mix ratio in the preparation of building materials such as concrete. In addition, for some applications with high requirements for sand and gravel quality, such as high-precision architectural decorative sand, damp sand and gravel will affect their appearance and texture. Therefore, it is necessary to dry them during the processing.
[0003] Because a large amount of dust is generated during the drying process of sand and gravel, existing drying devices are equipped with a dust suction mechanism to adsorb the dust. However, due to the large amount of dust, the filter screen is easily clogged during the dust suction process, resulting in poor dust suction effect and affecting the dust suction efficiency. Secondly, existing drying devices are equipped with a stirring mechanism to stir and dry the sand and gravel. However, because the stirring shaft cannot completely stir the bottom layer of sand and gravel, there will be a stirring dead zone, which in turn affects the drying efficiency of the sand and gravel. Utility Model Content
[0004] The purpose of this utility model is to provide a building material drying device to solve the problem mentioned in the background art that the existing drying device is equipped with a dust suction mechanism to adsorb dust. However, due to the large amount of dust, the filter screen is easily clogged during the dust suction process, resulting in poor dust suction effect. Secondly, there is the problem of a stirring dead zone.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a building material drying device, comprising a main body,
[0006] The main body has a drying chamber and a feeding chamber at both ends, and a discharge gate is provided at the bottom of the drying chamber. A hot air supply device is provided on the outside of the main body. A circulating feeding component is provided inside the feeding chamber. A material impact component is provided on the upper inner side of the drying chamber.
[0007] The top of the drying chamber has a dust suction chamber, and the inner wall of the dust suction chamber is fixed with an inclined plate. A fixed frame is also fixed inside the dust suction chamber, and a filter screen is set at the midpoint of the fixed frame. A fan is fixed to the outside of the dust suction chamber, and a collection box is set to the outside of the inclined plate. A cover plate is set above the fixed frame, and an arc-shaped plate is fixed to the top of the cover plate. The two ends of the top of the cover plate are connected to the inner wall of the dust suction chamber through spring telescopic rods. An inclined surface is set on the arc-shaped plate. A drive assembly is set on the top of the main body, and the drive assembly is used to drive the cover plate to move vertically back and forth.
[0008] Preferably, the circulating feeding assembly includes a motor, which is fixed to one end of the top of the main body and the output end of the motor is connected to the auger. The auger is vertically installed in the feeding chamber, and a guide plate is also fixed to the top of the inner wall of the drying chamber.
[0009] In the above technical solution, the sand and gravel at the bottom of the drying chamber can be transported from bottom to top and then fall from top to bottom, thereby increasing the heat-receiving area of the sand and gravel and thus improving the drying efficiency of the sand and gravel.
[0010] Preferably, the material striking assembly includes a striking plate, which is horizontally installed above the inner side of the drying chamber and connected to the output end of motor two, which is installed on the outer side of the main body.
[0011] In the above technical solution, the sand and gravel conveyed upward by the circulating feeding component can be struck to increase the distribution range of the sand and gravel and help increase the heating area of the sand and gravel.
[0012] Preferably, the drying chamber is provided with several sets of triangular plates.
[0013] In the above technical solution, the triangular plate can slow down the falling time of sand and gravel, thereby increasing the heating time of sand and gravel.
[0014] Preferably, the driving component includes a third motor, which is fixed to one top end of the main body, and the output end of the third motor is connected to the turntable. The turntable is installed inside the dust collection chamber, and a vertical rod is fixed to the bottom of the turntable.
[0015] In the above technical solution, the motor drives the turntable to rotate, which in turn drives the vertical rod to rotate. During the rotation, the bottom of the vertical rod will abut against the arc-shaped plate on the top of the cover plate. Since the arc-shaped plate has a slope, it will push the arc-shaped plate down, so that the arc-shaped plate will cause the cover plate to stick to the filter screen and stop the suction. When the vertical rod separates from the arc-shaped plate, the spring telescopic rod will drive the cover plate to rise and reset, so that the bottom of the dust collection chamber will generate suction again to adsorb the dust.
[0016] Compared with the prior art, the beneficial effects of this utility model are: this building material drying treatment device,
[0017] (1) When the dust is adsorbed by the fan, the filter screen can filter the dust. During this process, the cover plate can be driven to move vertically back and forth through the drive component. When the cover plate is close to the filter screen, the suction at the bottom of the dust suction chamber will stop. And because the cover plate will vibrate the filter screen when it is close to the filter screen, the dust on the filter screen can be shaken off onto the inclined plate and enter the collection box with the inclined plate. When the cover plate is separated from the filter screen, the dust suction chamber will generate suction again to adsorb the dust. This can avoid the dust from clogging the filter screen and affecting the dust suction effect. Compared with the method of cleaning by scraper, this technical solution can avoid the situation where the scraper scrapes the dust and then adsorbs it again. By stopping the generation of suction at regular intervals while the fan is running, the dust on the filter screen can be effectively shaken off, improving the effect of the filter screen.
[0018] (2) When drying sand and gravel, the bottom layer of sand and gravel in the drying chamber can be conveyed from bottom to top by the circulating feeding component and then fall from top to bottom. During this process, the sand and gravel can also be struck by the material striking component during the falling process to make the sand and gravel evenly distributed. The triangular plate can also reduce the falling speed of the sand and gravel, thereby increasing the drying time of the sand and gravel. This technical solution can dry the sand and gravel quickly by continuously conveying the sand and gravel and drying it during the falling process. It can also avoid the situation where the sand and gravel dead zone cannot be dried, which helps to improve the drying efficiency. Attached Figure Description

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.
[0024] Please see Figure 1-3 This utility model provides a technical solution: a drying device for building materials, such as... Figure 1 , Figure 2 and Figure 3 As shown, the main body 1 has a drying chamber and a feeding chamber at both ends, and a discharge gate 2 is provided at the bottom of the drying chamber. A hot air supply device is provided on the outside of the main body 1. A circulating feeding component 3 is provided inside the feeding chamber. A material impact component 5 is provided on the upper inside of the drying chamber.
[0025] The top of the drying chamber is provided with a dust collection chamber, and the inner wall of the dust collection chamber is fixed with an inclined plate 7. The dust collection chamber is also fixed with a fixed frame 8, and a filter screen 9 is set at the midpoint of the fixed frame 8. A fan 10 is fixed on the outside of the dust collection chamber, and a collection box 11 is set on the outside of the inclined plate 7. A cover plate 12 is set above the fixed frame 8, and an arc plate 13 is fixed on the top of the cover plate 12. The two ends of the top of the cover plate 12 are connected to the inner wall of the dust collection chamber through spring telescopic rods 14. An inclined surface is provided on the arc plate 13. A drive assembly 15 is set on the top of the main body 1. The drive assembly 15 is used to drive the cover plate 12 to move vertically back and forth.
[0026] like Figure 1 As shown, the circulating feeding assembly 3 includes a motor 301, which is fixed to one end of the top of the main body 1, and the output end of the motor 301 is connected to the auger 302. The auger 302 is vertically installed in the feeding chamber, and a guide plate 4 is also fixed to the top of the inner wall of the drying chamber.
[0027] like Figure 1 As shown, the material impact assembly 5 includes an impact plate 501, which is horizontally installed on the upper inner side of the drying chamber. The impact plate 501 is connected to the output end of the second motor 502, which is installed on the outer side of the main body 1.
[0028] like Figure 1 As shown, several sets of triangular plates 6 are installed inside the drying chamber.
[0029] like Figure 1 , Figure 2 and Figure 3As shown, the drive assembly 15 includes a motor 1501, which is fixed to one end of the top of the main body 1. The output end of the motor 1501 is connected to the turntable 1502, which is installed inside the dust collection chamber. A vertical rod 1503 is fixed to the bottom of the turntable 1502.
[0030] Working Principle: During operation, sand and gravel are first introduced into the drying chamber inside the main body 1, and the hot air supply equipment is turned on to generate hot air. Then, motor 301 is turned on to drive the auger 302 to rotate, causing the auger 302 to transport the sand and gravel from the bottom of the drying chamber upwards, allowing the sand and gravel to fall from the top of the drying chamber, thereby increasing the heating area of the sand and gravel. During the falling process, motor 502 can be turned on to drive the impact plate 501 to rotate, which will strike the falling sand and gravel to prevent it from accumulating into clumps. The triangular plate 6 can also reduce the falling time of the sand and gravel, improving its drying efficiency. During the drying process, fan 10 can be turned on to generate negative pressure, creating suction at the bottom of the dust collection chamber. The filter screen 9 on the fixed frame 8 can intercept and filter dust. Motor 1501 can be turned on to drive the turntable 1502 to rotate, which in turn drives the vertical rod 1503 to rotate. During rotation, the bottom of the 1503 motor abuts against the arc-shaped plate 13 on top of the cover plate 12. Because the arc-shaped plate 13 has an inclined surface, it pushes the plate downwards, causing the cover plate 12 to come into contact with the filter screen 9, stopping suction. Furthermore, the vibration of the filter screen 9 when the cover plate 12 is in contact with it dislodging dust onto the inclined plate 7, which then enters the collection box 11. When the vertical rod 1503 separates from the arc-shaped plate 13, the spring telescopic rod 14 causes the cover plate 12 to rise and reset, regenerating suction at the bottom of the suction chamber to adsorb dust. This prevents dust from clogging the filter screen 9 and affecting suction performance. The cleaning frequency of the filter screen 9 can be increased or decreased by adjusting the speed of the motor 1501, allowing for adjustments based on usage.
[0031] This completes the entire operation, and anything not described in detail in this specification is prior art known to those skilled in the art.
