Description

Technical Field

[0001] This utility model relates to the field of equipment manufacturing, and in particular to a complete set of equipment for a high-strength wind power grouting material production line. Background Technology

[0002] As a key material for fixing the foundations of wind power generation equipment, the accuracy of raw material proportioning plays a decisive role in the performance of wind power grouting materials. Aggregates, active admixtures, and additives of different particle sizes must be strictly metered and mixed according to the specified ratio. The proportioning of raw materials with different particle sizes adjusts the product's density to improve its strength; any slight deviation can lead to substandard strength and uniformity of the grouting material. Simultaneously, density is a crucial indicator of the quality of wind power grouting materials. The grouting material must possess good fluidity and self-compacting ability to ensure it can fully fill the foundation voids during pouring, forming a tight and stable structure. However, currently, the high requirements for wind power grouting material proportioning in China are largely met by the use of decentralized equipment combinations in production. Poor coordination between equipment in each stage makes it difficult to achieve precise raw material proportioning and effectively control the density during production, resulting in inconsistent product quality. Furthermore, due to the high density requirements of high-strength grouting materials, the sand particles are all in the micron range, making them extremely prone to sedimentation at the bottom of the silo, leading to material arching and blockage, causing supply interruptions and affecting production continuity. This results in insufficient accuracy in the metering process, making it difficult to precisely control the proportions of various raw materials, causing significant fluctuations in the quality of the grouting material. Moreover, the storage, packaging, and stacking of finished products largely rely on manual operations, which is not only inefficient but also prone to problems such as non-standard packaging and messy stacking, increasing labor costs and management difficulty. Therefore, developing a complete set of equipment for a high-strength wind power grouting material production line that is highly integrated and automated, capable of efficient raw material processing, precise proportioning and mixing, and efficient post-processing of finished products, has become an urgent technical problem to be solved. Utility Model Content

[0003] The purpose of this utility model is to provide a complete set of equipment for a high-strength wind power grouting material production line, so as to solve the problems of poor connection, low raw material utilization, unstable product quality and low production efficiency of existing wind power grouting material production equipment, and realize the automation, continuity and precision of the entire grouting material production process, thereby improving product quality and production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a complete set of equipment for a high-strength wind power grouting material production line, including a fish-scale plate conveyor, a jaw crusher, a first vibrating screen, a single-cylinder hydraulic cone crusher, a sand making tower, a square gyratory screen, a scraper conveyor, a silo, and a concrete mixing tower. Mineral raw materials are conveyed to the jaw crusher via the fish-scale plate conveyor. The discharge port of the jaw crusher conveys the crushed mineral raw materials to the first vibrating screen via a main conveyor belt. Unqualified raw materials separated by the first vibrating screen are conveyed to the single-cylinder hydraulic cone crusher via a return belt. The discharge port is located above the main conveyor belt, and the main conveyor belt transports the crushed raw materials to the first vibrating screen. The first vibrating screen uses an elevator to transport qualified raw materials to the sand making plant for sand making. The sand is then transported to the square gyratory screen via a conveyor belt and an elevator. The square gyratory screen divides the sand into multiple grades of aggregated raw materials according to different particle sizes based on the aggregate requirements, and then transports them to the corresponding silos for temporary storage via a scraper conveyor and an elevator. The silos are all located on the top of the concrete mixing plant and are precisely fed into the concrete mixing plant. The concrete mixing plant aggregates and mixes the raw materials to form the final product, which is then bagged and output.

[0005] Preferably, the sand making tower consists of a sand making machine, a second vibrating screen, and a non-powered air classifier from top to bottom. The first vibrating screen conveys qualified raw materials to the sand making machine via an elevator. The discharge port at the bottom of the sand making machine is connected to the interior of the second vibrating screen. The second vibrating screen returns the unqualified sand material to the sand making machine for secondary grinding and crushing. The qualified sand material is conveyed to the non-powered air classifier for air separation. The non-powered air classifier conveys the air-separated powder to the corresponding silo for temporary storage via a pneumatic conveying pipeline. The remaining sand material is conveyed to the square gyratory screen for grading and screening via a conveyor belt and an elevator.

[0006] Preferably, the silo consists of multiple sand silos and powder silos, all of which are located on the top of the concrete mixing plant.

[0007] Preferably, the concrete mixing plant consists of a metering hopper, a mixing host, a finished product storage silo, and a packaging machine from top to bottom. The silos are connected to the metering hopper via discharge pipes. The bottom of the metering hopper is connected to the inlet of the mixing host via a conveying pipe. The outlet of the mixing host is connected to the inside of the finished product storage silo. The finished product storage silo is transported to the packaging machine for packaging via a discharge pipe.

[0008] Preferably, the discharge pipes at the bottom of the silo are equipped with screw conveyors for precise feeding and pneumatic gate valves for controlling the discharge switch.

[0009] Preferably, the bottom conical part of the silo is equipped with a pneumatic arch-breaking device.

[0010] Preferably, the finished product storage silo is equipped with an upper / lower material level indicator.

[0011] Preferably, the conical bottom of the finished product storage silo is equipped with a pneumatic arch-breaking device and a vibration motor.

[0013] Preferably, the product also includes an automatic palletizing device, which stacks the finished bagged products packaged by the packaging machine into the finished product workshop.

[0014] Compared with the prior art, the advantages of this utility model are: 1. This utility model realizes fully automated continuous production. Through the reasonable connection and cooperation of various equipment, from the transportation, crushing, screening and sand making of mineral raw materials, to the graded storage, metering and mixing of raw materials, and then to the storage, packaging and palletizing of finished products, a complete automated production line is formed. It does not require a lot of manual intervention and greatly improves the continuity and efficiency of production. 2. By combining a jaw crusher and a single-cylinder hydraulic cone crusher in a two-stage crushing process, along with the screening by the first vibrating screen and the return mechanism for unqualified raw materials, the crushed particle size of the raw materials is ensured to meet the requirements, and material waste is reduced without the need for manual intervention.

[0015] 3. The sand is precisely graded and screened according to the collection and distribution requirements using a square gyratory screen, and then transported to the corresponding silos for storage so that it can be centrally collected and distributed according to different particle sizes. The whole process is completed automatically and cannot be manually intervened.

[0016] 4. Due to the small particle size of the raw sand, the pneumatic arch-breaking device at the bottom cone of the silo and the pneumatic arch-breaking device at the bottom cone of the finished product storage silo can effectively prevent material arching and blockage, ensuring smooth material supply and discharge. 5. To reduce the intensity of manual labor, automatic palletizing equipment is used to replace manual palletizing, thereby improving the efficiency and standardization of finished product stacking, reducing labor input, lowering labor costs, and reducing the difficulty of subsequent management.

[0019] The present invention will be further described below: A complete set of equipment for a high-strength wind power grouting material production line, see [link to relevant documentation]. Figures 1 to 3 The system includes a fish-scale conveyor 1, a jaw crusher 2, a first vibrating screen 3, a single-cylinder hydraulic cone crusher 4, a sand making tower 5, a square gyratory screen 6, a scraper conveyor 7, a silo 8, and a concrete mixing tower 9. Mineral raw materials are conveyed to the jaw crusher 2 via the fish-scale conveyor 1. The discharge port of the jaw crusher 2 conveys the crushed mineral raw materials to the first vibrating screen 3 via a main conveyor belt. Unqualified raw materials separated by the first vibrating screen 3 are conveyed to the single-cylinder hydraulic cone crusher 4 via a return conveyor belt 12. The discharge port of the single-cylinder hydraulic cone crusher 4 is located above the main conveyor belt, and the main conveyor belt conveys the raw materials to the first vibrating screen 3 for further crushing. The first vibrating screen 3 conveys qualified raw materials to the sand making tower 5 for sand making via an elevator 13. This utility model achieves an automated process for mineral raw materials from conveying, crushing to preliminary screening through the coordinated operation of equipment such as fish scale plate conveyor 1, jaw crusher 2, first vibrating screen 3, and single-cylinder hydraulic cone crusher 4. The recycling crushing mechanism for unqualified raw materials ensures that the particle size of the raw materials entering the subsequent processes meets the standards, improves the utilization rate of raw materials and product quality, and lays a good foundation for the subsequent sand making and distribution stages.

[0020] Taking a certain high-strength wind power grouting material as an example, its raw material ratio is as follows: 400-450 parts of high-strength 525 silicate cement, 150-200 parts of 10-40 mesh mineral sand admixture, 100-150 parts of 40-70 mesh mineral sand admixture, and 70-100 mesh mineral sand admixture are balanced. All materials are measured according to the ratio and put into the mixing host in sequence for periodic mixing. During mixing, 3% additives and 1.2%-2% steel fibers are added. After mixing, the mixture is bagged to obtain a wind power grouting material product with a 28-day strength of 120-150 MPa.

[0021] The sand making tower 5 consists of a sand making machine 51, a second vibrating screen 52, and a non-powered air classifier 53, arranged from top to bottom. The first vibrating screen 3 conveys qualified raw materials to the sand making machine 51 via an elevator 13. The discharge port at the bottom of the sand making machine 51 is connected to the interior of the second vibrating screen 52. The second vibrating screen 52 returns the unqualified sand material to the sand making machine 51 for secondary grinding and crushing. The qualified sand material is then conveyed to the non-powered air classifier 53 for air separation. The non-powered air classifier 53 separates dust particles larger than 100 mesh and conveys them to the corresponding silos 8 via pneumatic conveying pipes for temporary storage and use as admixture. The remaining sand material is conveyed to the square gyratory screen 6 via a conveyor belt and elevator 13 for grading and screening. The sand making tower 5 adopts a combination of sand making machine 51, second vibrating screen 52 and non-powered air classifier 53 to form an efficient sand making and screening system. The sand making machine 51 can grind and crush the crushed raw materials into sand that meets the aggregate particle size requirements. The second vibrating screen 52 can screen out the unqualified sand produced by the sand making machine 51 and return it to the sand making machine 51 for secondary grinding and crushing, ensuring the particle size qualification of the sand raw materials. Through the air classification function of the non-powered air classifier 53, smaller particle size dust can be separated and stored separately for grading, while larger particle size sand is transported to square gyratory screen 6 for grading.

[0022] The prepared sand is conveyed to the square gyratory screen 6 via a conveyor belt and elevator 13. The square gyratory screen 6 separates the sand into multiple grades of aggregate raw materials according to different particle sizes based on the aggregation requirements, and then conveys them to the corresponding silos 8 for temporary storage via scraper conveyor 7 and elevator 13. Because wind power grouting materials have stringent requirements for the proportioning accuracy of sand of different particle sizes (deviation must be controlled within ±2%), the square gyratory screen 6 achieves high-precision screening with its unique "simulated manual gyratory" motion trajectory. The screen uses high-precision woven or perforated mesh with a mesh size error ≤0.05mm. After the mineral admixture is sanded by the sand making machine, it can be accurately separated into three grades of mineral sand: 10-40 mesh, 40-70 mesh, and 70-100 mesh, according to the aggregation requirements, with a grading efficiency of over 95%, ensuring uniform particle size of each grade of raw material and laying the foundation for subsequent precise mixing.

[0023] The silos 8 are all located on top of the concrete mixing plant 9 and are connected to the inlet of the mixing host 92 inside the concrete mixing plant 9. This layout is compact and reasonable, reducing the material transportation distance and energy consumption, facilitating the transportation of materials to the mixing plant, and also making it easier to classify, store, and manage different types of materials. The concrete mixing plant 9 consists of a metering hopper 91, a mixing host 92, a finished product storage silo 93, and a packaging machine 94 from top to bottom. The silos 8 are connected to the metering hopper 91 through discharge pipes. The bottom of the metering hopper 91 is connected to the inlet of the mixing host 92 through a conveying pipe. The outlet of the mixing host 92 is connected to the interior of the finished product storage silo 93. The finished product storage silo 93 is transported to the packaging machine 94 through a discharge pipe for packaging. The orderly arrangement of the metering hopper 91, mixing host 92, finished product storage silo 93, and packaging machine 94 in the concrete mixing plant 9 from top to bottom realizes the full-process automation from material metering, mixing, finished product storage to packaging. Precise metering and thorough mixing ensure the stability of product quality. The setting of finished product storage silo 93 and packaging machine 94 improves production efficiency and facilitates product storage and transportation.

[0024] Regarding equipment selection: The reason for using fish scale plate conveyor 1 is that most mineral raw materials are in the form of blocks or granules. The conveyor belt of fish scale plate conveyor 1 is composed of overlapping "fish scale" metal plates. The metal plates are usually made of wear-resistant steel, which can withstand the impact and friction of blocky raw materials, thus avoiding problems such as belt scratches and tears that occur in ordinary belt conveyors due to the sharp edges and heavy weight of the raw materials.

[0025] The jaw crusher 2 boasts exceptional coarse crushing capabilities. Its deep and well-contained crushing chamber allows for the smooth entry of large pieces of raw material. Through the periodic oscillation of the moving jaw, it applies compression and shearing forces to the material, rapidly crushing blocks with diameters of tens of centimeters to a particle size (typically 10-30mm) suitable for subsequent processing. Compared to other coarse crushing equipment, it has a higher throughput per unit time, meeting the continuous feeding needs of production lines and preventing material accumulation due to insufficient crushing capacity.

[0026] The single-cylinder hydraulic cone crusher 4 uses the principle of layered crushing to perform secondary crushing on unqualified raw materials, so that they meet the particle size requirements of the sand making machine 51.

[0027] The silo 8 consists of multiple sand and powder silos, which can store materials of different particle sizes separately for batching. The admixtures used in the mixture are transported to the concrete mixing plant 9 by electric hoists. The admixtures are weighed separately and manually fed into the mixing host 92. After each feeding, the mixing host 92 is started manually by pressing the switch. The mixing host is then unloaded after a period of time.

[0028] Each of the silos 8 is equipped with a screw conveyor 95 for precise feeding and a pneumatic gate valve for controlling its feeding switch on the feeding pipe at the bottom. This enables precise material feeding and feeding control, avoids material waste and blockage during the feeding process, and ensures the continuity and stability of the production process.

[0029] The bottom conical part of the silo 8 is equipped with a pneumatic arch-breaking device, which effectively prevents the raw materials from accumulating into arches inside the silo, ensures that the sand can be fed smoothly and accurately, guarantees product quality, enables normal production, and reduces manual intervention and equipment failure.

[0030] The finished product storage silo 93 is equipped with an upper / lower level indicator to prevent overflow or emptying. When the upper / lower level indicator shows a reading, the mixing host 92 does not feed material. The conical bottom of the finished product storage silo 93 is equipped with a pneumatic anti-bridging device and a vibration motor to ensure the flowability of materials within the silo, prevent material agglomeration, and ensure smooth discharge from the bottom outlet pipe, providing a stable material supply for subsequent packaging processes. The bottom outlet pipe of the finished product storage silo 93 is equipped with a pneumatic gate valve to control the entry of finished material into the packaging machine 94 system for bagging.

[0031] It also includes an automatic palletizing device 10, which stacks the finished bagged products packaged by the packaging machine 94 into the finished product workshop, realizing the automation of finished product stacking, greatly reducing the intensity of manual labor, improving production efficiency, and also making the finished product stacking more neat and orderly, which is convenient for management and storage.
