Description

Technical Field

[0001] This utility model belongs to the field of quartz sand production technology, and in particular to a quartz sand production conveying device. Background Technology

[0002] Quartz sand, as an important industrial raw material, is widely used in glass manufacturing, casting, chemical industry, and many other fields. In the production and processing of quartz sand, conveying devices are key equipment to ensure the smooth transfer of materials from one processing stage to the next. Traditional quartz sand production conveying devices mainly include basic components such as screw conveyors, used to achieve continuous transport of quartz sand.

[0003] However, these traditional devices often exhibit significant shortcomings when dealing with the high hardness and abrasiveness of silica sand. For example, in traditional silica sand production and conveying equipment, metal materials are typically used for the inner wall of the conveying pipe. However, silica sand has high hardness and abrasiveness. During material conveying, especially at high speeds or when the material particles are large, the friction between the silica sand and the inner wall of the conveying pipe can lead to severe wear. If this problem is not solved, the inner wall of the conveying pipe will be rapidly worn down, resulting in a significant reduction in equipment lifespan and potentially causing a decrease in conveying efficiency or even malfunction.

[0004] A search revealed a Chinese patent publication number: CN213140266U, which describes a conveying device for quartz sand production. The device includes an electric motor, a speed reducer installed at the output end of the motor, and a circular tube installed on one side of the speed reducer. The speed reducer is rotatably connected to a spiral rod inside the circular tube via a transmission shaft. A sliding plate, in conjunction with a slide rail, slides cyclically along the outer wall of the circular tube. The vibration force generated by the vibrating motor, in conjunction with a vibrating plate, is transmitted to the circular tube inside the sliding plate, loosening the quartz sand clogged inside the tube. The spiral rod then continues to transport the loosened quartz sand.

[0005] The patent documents cited above also have the same problem. During the material conveying process, especially when the conveying speed is high or the material particles are large, the friction between the quartz sand and the inner wall of the conveying pipe will cause serious wear. If this problem is not solved, the inner wall of the conveying pipe will be worn down quickly. Utility Model Content

[0006] The purpose of this invention is to provide a quartz sand production and conveying device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quartz sand production conveying device, comprising a screw conveyor assembly, the screw conveyor assembly comprising a conveying pipe, a feed inlet disposed on the top surface of one end of the conveying pipe, a discharge outlet disposed on the bottom surface of the other end of the conveying pipe, a conveying shaft rotatably installed in the conveying pipe, screw conveying blades fixed to the periphery of the conveying shaft, and a drive mechanism disposed at one end of the conveying pipe and driving the conveying shaft to rotate. The outer wall of the conveying pipe is symmetrically cut with rectangular mounting openings, each of the rectangular mounting openings is equipped with a detachable arc-shaped side plate, each of the detachable arc-shaped side plates is provided with an anti-wear and anti-clogging component, the anti-wear and anti-clogging component comprising a cylinder component installed on the outer wall of the detachable arc-shaped side plate, an anti-wear rubber sheet adhered to the inner wall of the detachable arc-shaped side plate, multiple spring components symmetrically fixedly installed on the inner wall of the detachable arc-shaped side plate and wrapped in the anti-wear rubber sheet, and a piston rod connected to the cylinder component and penetrating the detachable arc-shaped side plate. The design of the anti-wear rubber pads reduces wear on the inner wall of the conveying pipe when the quartz sand is conveyed by the conveying shaft and spiral conveying blades. When the quartz sand impacts the anti-wear rubber pads, the spring mechanism cushions the impact and provides elastic reaction force to the sand, thus pushing it forward and reducing the risk of blockage. Furthermore, the cylinder intermittently pushes the anti-wear rubber pads via the piston rod, further pushing the quartz sand in the conveying pipe and minimizing blockage. The drive mechanism includes a gear set at one end of the conveying pipe and a servo motor connected to the gear set. The servo motor drives the gear set, thereby rotating the conveying shaft within the conveying pipe. Support feet are symmetrically welded to the bottom of the conveying pipe.

[0008] In a preferred embodiment, a top plate is fixedly installed at the end of the piston rod away from the cylinder component, and the top plate dynamically abuts against and impacts the inner wall of the anti-wear rubber sheet.

[0009] In a preferred embodiment, both ends of the top plate are provided with concentrically extending notches or grooves. These notches or grooves allow the spring to pass through, ensuring that the top plate and spring are misaligned when the piston rod pushes the top plate, thus preventing motion interference.

[0010] In this preferred embodiment, each notch has chamfered ends integrally formed on both sides and at both ends of the top piece. The chamfered ends prevent the inner wall of the wear-resistant rubber sheet from being scratched upon impact.

[0011] In a preferred embodiment, an adhesive ring is provided on the inner edge of the wear-resistant rubber sheet. The adhesive ring is sealed and bonded to the inner wall of the detachable arc-shaped side plate, thereby forming a cavity between the wear-resistant rubber sheet and the inner wall of the detachable arc-shaped side plate to accommodate the spring and the top plate.

[0012] In a preferred embodiment of this design, each of the detachable arc-shaped side plates has a through hole at the middle of its outer wall for the piston rod to pass through.

[0013] In a preferred embodiment, the cylinder component has a mounting base plate at one end near the piston rod, and the mounting base plate is fixedly mounted on the outer wall of the detachable arc-shaped side plate by bolts.

[0014] In this preferred embodiment, at least two blades in the middle section of the spiral conveying blade are provided with an anti-clogging impact structure. When the spiral conveying blade drives the conveying of quartz sand, the anti-clogging impact structure can further elastically impact the quartz sand in the middle section, further reducing clogging.

[0015] In this preferred embodiment, each of the anti-clogging impact structures includes two fixing rings symmetrically installed on the outer wall of the spiral conveyor blade and an elastic pull bar fixedly connected between the two fixing rings.

[0016] In this preferred embodiment, a top rod is fixed between the two fixed rings and on the outer wall of the spiral conveying blade. The end of the top rod away from the spiral conveying blade is welded to the middle section of the elastic strip, and the top rod supports the stretched elastic strip to form a triangular structure. When the quartz sand impacts the elastic strip, the elastic strip is stretched and supported, increasing its elasticity and further exerting elastic reaction force on the quartz sand during the conveying process, thus reducing blockage.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0018] This quartz sand production and conveying device effectively reduces the direct contact and abrasion of the inner wall of the conveying pipe by symmetrically cutting rectangular installation openings on the outer wall of the conveying pipe and installing detachable arc-shaped side plates with anti-wear rubber sheets. When the quartz sand comes into contact with the anti-wear rubber sheets during conveying, the wear rate is significantly reduced due to the properties of the rubber material. In addition, spring components wrapped inside the anti-wear rubber sheets provide additional cushioning, further mitigating the impact of impact forces on the inner wall of the conveying pipe.

[0019] The anti-wear and anti-clogging assembly, consisting of a cylinder, piston rod, and top plate, along with the anti-clogging impact structure on the spiral conveyor blades, works together to reduce the risk of clogging. The cylinder intermittently pushes the piston rod, causing the top plate to dynamically impact the anti-wear rubber sheet, indirectly propelling the quartz sand forward. Simultaneously, the elastic tension bar in the middle section of the spiral conveyor blades is stretched and formed into a triangular structure, increasing the elastic reaction force on the quartz sand, which helps maintain smooth material flow and reduces the occurrence of clogging.

[0029] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0030] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0031] This embodiment provides, for example Figures 1 to 6 The illustrated quartz sand production conveying device includes a screw conveyor assembly 1. The screw conveyor assembly 1 includes a conveying pipe 2, a feed inlet 3 located on the top surface of one end of the conveying pipe 2, a discharge outlet 4 located on the bottom surface of the other end of the conveying pipe 2, a conveying shaft 20 rotatably mounted in the conveying pipe 2, screw conveying blades 21 fixed to the periphery of the conveying shaft 20, and a drive mechanism located at one end of the conveying pipe 2 and driving the conveying shaft 20 to rotate. The outer periphery of the conveying pipe 2 is symmetrically cut with rectangular mounting openings. Each rectangular mounting port is equipped with a detachable arc-shaped side plate 6. Each detachable arc-shaped side plate 6 is provided with an anti-wear and anti-clogging component 10. The anti-wear and anti-clogging component 10 includes a cylinder component 9 installed on the outer wall of the detachable arc-shaped side plate 6, an anti-wear rubber sheet 12 bonded to the inner wall of the detachable arc-shaped side plate 6, multiple spring components 14 symmetrically fixedly installed on the inner wall of the detachable arc-shaped side plate 6 and wrapped in the anti-wear rubber sheet 12, and a piston rod 17 connected to the cylinder component 9 and passing through the detachable arc-shaped side plate 6. The design of the anti-wear rubber sheet 12 reduces wear on the inner wall of the conveying pipe 2 when the quartz sand is conveyed in the conveying pipe 2 by the conveying shaft 20 and the spiral conveying blades 21. Simultaneously, when the quartz sand impacts the anti-wear rubber sheet 12, the spring 14 cushions the rubber sheet and provides elastic reaction force to the quartz sand, thus pushing it forward and reducing the risk of blockage in the conveying pipe 2. Furthermore, the cylinder 9 intermittently pushes the anti-wear rubber sheet 12 via the piston rod 17, further pushing the quartz sand in the conveying pipe 2 and reducing blockage. The drive mechanism includes a gear set 8 located at one end of the conveying pipe 2 and a servo motor 7 connected to the gear set 8, causing the servo motor 7 to drive the gear set 8, thereby rotating the conveying shaft 20 in the conveying pipe 2. Support legs 5 are symmetrically welded to the bottom surface of the conveying pipe 2.

[0032] In this embodiment, a top plate 16 is fixedly installed at the end of the piston rod 17 away from the cylinder component 9. The top plate 16 dynamically abuts against the inner wall of the anti-wear rubber sheet 12. The cylinder component 9 intermittently pushes the top plate 16 through the piston rod 17, which in turn acts on the anti-wear rubber sheet 12, indirectly pushing the quartz sand forward. This further enhances the anti-clogging function, ensures smooth material flow, and reduces clogging problems caused by accumulation.

[0033] In this embodiment, both ends of the top plate 16 are provided with concentrically extending notches 15. The notches 15 allow the spring 14 to pass through, ensuring that when the piston rod 17 pushes the top plate 16, the top plate 16 and the spring 14 are misaligned. This prevents motion interference. When the piston rod 17 pushes the top plate 16, the top plate 16 and the spring 14 are misaligned, avoiding motion interference and ensuring that the top plate 16 can move freely without being affected by the spring 14, thus ensuring the stability and efficiency of the system.

[0034] In this embodiment, each notch 15 has a chamfered end 18 integrally formed on both sides and at both ends of the top piece 16. The chamfered end 18 is designed to prevent scratching the inner wall of the anti-wear rubber sheet 12 when it is impacted. The chamfered end 18 design avoids scratches or damage that may be caused when impacting the anti-wear rubber sheet 12, protects the anti-wear rubber sheet 12 from mechanical damage, extends its service life, and maintains the sealing and stability of the system.

[0035] In this embodiment, an adhesive ring 13 is provided on the inner edge of the wear-resistant rubber sheet 12. The adhesive ring 13 is sealed and bonded to the inner wall of the detachable arc-shaped side plate 6, forming a cavity between the wear-resistant rubber sheet 12 and the inner wall of the detachable arc-shaped side plate 6 to accommodate the spring member 14 and the top plate member 16. The adhesive ring 13 provides good sealing performance, forming an independent space to accommodate the spring member 14 and the top plate member 16, enhancing the system's sealing performance, protecting internal components from external influences, and ensuring that the spring member 14 and the top plate member 16 can operate normally in a closed environment.

[0036] In this embodiment, each detachable arc-shaped side plate 6 has a through hole 19 in the middle of its outer wall for the piston rod 17 to pass through.

[0037] In this embodiment, the cylinder component 9 has a mounting base plate 11 at one end near the piston rod 17. The mounting base plate 11 is fixedly mounted on the outer wall of the detachable arc-shaped side plate 6 by bolts.

[0038] In this embodiment, at least two blades in the middle section of the spiral conveying blade 21 are provided with anti-clogging impact structures. When the spiral conveying blade 21 drives the conveying of quartz sand, the anti-clogging impact structures can further elastically impact the quartz sand in the middle section, further reducing clogging.

[0039] In this embodiment, each anti-clogging impact structure includes two fixing rings 22 symmetrically installed on the outer wall of the spiral conveyor blade 21 and an elastic pull bar 23 fixedly connected between the two fixing rings 22.

[0040] In this embodiment, a top rod 24 is fixed between the two fixing rings 22 and on the outer wall of the spiral conveying blade 21. The end of the top rod 24 away from the spiral conveying blade 21 is welded to the middle section of the elastic pull strip 23, and the top rod 24 supports the stretched elastic pull strip 23 to form a triangular structure. When the quartz sand impacts the elastic pull strip 23, the elasticity of the elastic pull strip 23 increases due to the stretching and support, thereby further reducing the elastic reaction force on the quartz sand during the conveying process and reducing blockage.

[0041] Working principle

[0042] In this quartz sand production and conveying device, quartz sand enters the conveying pipe 2 through the feed port 3 located on the top surface of one end of the conveying pipe 2. The servo motor 7 is started, driving the gear set 8, which in turn drives the conveying shaft 20 to rotate. The spiral conveying blades 21 fixed around the conveying shaft 20 rotate accordingly, gradually pushing the quartz sand forward along the conveying pipe 2. During the conveying process, rectangular installation openings are symmetrically cut on the inner wall of the conveying pipe 2, and detachable arc-shaped side plates 6 are installed at these positions. Each detachable arc-shaped side plate 6 has an anti-wear rubber sheet 12 bonded inside. The anti-wear rubber sheet 12 can not only effectively reduce the direct wear of the quartz sand on the inner wall of the conveying pipe 2, but also play a buffering role when the quartz sand is impacted.

[0043] Multiple springs 14 are symmetrically fixed to the inner wall of the detachable arc-shaped side plate 6, which are wrapped in the anti-wear rubber sheet 12. When the quartz sand hits the anti-wear rubber sheet 12, the springs 14 can provide elastic reaction force, which helps to push the quartz sand forward and reduce the risk of blockage. The cylinder 9 intermittently pushes the anti-wear rubber sheet 12 through the piston rod 17 to further help move the quartz sand and prevent blockage.

[0044] At least two blades in the middle section of the spiral conveyor blade 21 are provided with anti-clogging impact structures, including a fixing ring 22, an elastic pull bar 23 and a push rod 24. When the spiral conveyor blade 21 rotates, these components can elastically impact and push the quartz sand, reducing the possibility of clogging.

[0045] After the above steps, the quartz sand is successfully transported to the discharge port 4 at the bottom of the other end of the conveying pipe 2, completing the entire conveying process.

[0046] When maintenance is required, the mounting base plate 11 can be removed by loosening the bolts, which makes it easy to disassemble the cylinder component 9 and facilitate the inspection or replacement of internal parts. In addition, the design of the detachable arc-shaped side plate 6 also facilitates the quick replacement of the anti-wear rubber sheet 12.
