Description

Technical Field

[0001] This invention relates to the field of mortar production and conveying equipment technology, and in particular to an adaptive fluidized dual-mode linkage vertical lifting mortar conveying device. Background Technology

[0002] In mortar production, the supply of dry sand (sand with extremely low moisture content) is achieved through vertical lifting. This is a common process, but one with many technical challenges. In practice, we have found that traditional and current mainstream technologies have the following main drawbacks: 1. Bucket Elevator: Disadvantages: Suitable for granular materials, but for completely dry fine sand, it is prone to serious dust generation during loading and unloading, polluting the environment. Friction between the bucket and the casing can easily generate static electricity, posing a safety hazard. When the lifting height is limited, the problem of material return (sand particles spilling from the bucket) is serious. It is inefficient and the equipment wears out quickly, especially for dry sand containing quartz, where the wear is particularly severe.

[0003] II. Pneumatic conveying (dilute phase / dense phase): Disadvantages: extremely high energy consumption (high fan power), for highly abrasive materials such as dry sand, the wear rate of pipelines (especially bends) is astonishing, the maintenance cost is high, the system is complex, and the requirements for air source quality and pipeline sealing are high. The conveying stability is greatly affected by the moisture content and particle size of the sand, and pipe blockage is prone to occur. The end separation and dust removal equipment is huge.

[0004] 3. Screw conveyor (vertical): Disadvantages: Limited lifting height and conveying capacity; high frictional resistance between dry sand and screw blades and pipe wall, resulting in high power consumption; and the intermediate hanger bearing is easily jammed or worn out by sand particles, making maintenance extremely inconvenient. It is not suitable for long-distance, high-height continuous lifting.

[0005] IV. Belt conveyor (large angle): Disadvantages: It cannot achieve true vertical lifting, requires a large site space, dry sand is easy to spill and generate dust at belt bends and high speed operation, and the anti-deviation and cleaning devices have high requirements.

[0006] In summary, existing technologies generally suffer from drawbacks such as "high wear, high energy consumption, high dust, easy failure, and difficult maintenance".

[0007] To address the aforementioned problems, this invention provides improvements. Summary of the Invention

A microporous airflow liner is vertically and equally spaced on one side of the pneumatic manifold located inside the lifting pipe. Uniformly distributed airflow holes are opened on one side of the microporous airflow liner. A discharge chamber is connected to the top of the lifting pipe. A rotary feed valve is fixedly installed on the top of the discharge chamber. The inlet end of the rotary feed valve is connected to the discharge chamber. A rotary feeding valve 2 is connected to the bottom of one side of the lifting pipe. The rotary feeding valve 2 is installed on the ground. The bottom end of the lifting pipe is connected to a feeding hopper set on the ground. A fan is connected to one side of the feeding hopper.

The output shaft of the drive motor passes through the interior of the lifting pipe and is fixedly connected to the chain conveyor belt. A porous airflow distribution plate is fixedly connected to the inner cavity of the feeding hopper. A controllable low-pressure air chamber is formed between the lower surface of the porous airflow distribution plate and the inner wall of the feeding hopper.

[0010] The present invention further comprises, as described above, an adaptive fluidized dual-mode linkage dry sand vertical lifting mortar station: the microporous airflow liner is provided with uniformly distributed airflow holes on the side facing the chain conveyor belt.

[0011] The present invention further comprises, as described above, an adaptive fluidized dual-mode linkage dry sand vertical lifting mortar station: two sand processing devices are fixedly installed on the top of the mounting frame, and the bottom of the sand processing devices are connected to two discharge pipes.

[0012] The present invention further comprises, as described above, an adaptive fluidized dual-mode linkage dry sand vertical lifting mortar station: multiple pre-embedded piles are fixedly installed at the bottom of the mounting frame, and the pre-embedded piles are buried into the ground by casting.

[0013] The present invention further comprises, as described above, an adaptive fluidized dual-mode linkage dry sand vertical lifting mortar station: a workbench is fixedly installed on the top of the two sand processing devices, and a material distribution device is fixedly installed on the top of the workbench.

[0014] The present invention, as described above, is for an adaptive fluidized dual-mode linkage dry sand vertical lifting mortar station, further comprising: the bottom of the material distribution device is connected to multiple material supply pipes II, and the ends of the multiple material supply pipes II away from the material distribution device are respectively connected to the tops of two sand processing devices.

[0015] The present invention further comprises, as described above, an adaptive fluidized dual-mode linkage dry sand vertical lifting mortar station: the top of the material distribution device is connected to a material supply pipe, one end of which is connected to the outlet of a rotary material supply valve.

[0016] The present invention further comprises, as described above, an adaptive fluidized dual-mode linkage dry sand vertical lifting mortar station: a liftable support is fixedly installed on one side of the workbench, and the lifting pipe is liftably installed on the outside of the liftable support.

[0019] In summary, the beneficial effects of the present invention are as follows: 1. This invention has a revolutionary effect in reducing wear: the "air cushion" makes the sand material non-contact or lightly contact the wall surface, which solves the fundamental problem of the strong abrasiveness of dry sand and the life of key components is expected to be extended by 3 to 5 times.

[0020] Significant energy savings: Due to a substantial reduction in friction, the motor power consumption of the mechanical drive component can be reduced by 30% to 50%. The auxiliary air flow rate is much smaller than that of pneumatic conveying, resulting in a clear advantage in overall energy consumption.

[0023] Easy to maintain: Modular structure, few vulnerable parts (mainly chain plates), and easy to replace.

[0024] 2. The present invention uses airflow holes, which are formed on the microporous airflow liner and face the chain conveyor belt. This allows a small amount of gas to seep out from the airflow holes, forming an extremely thin "air cushion film" between the chain / sand and the pipe wall. This reduces the wear of the sand on the pipe wall and extends the service life of the lifting device.

[0025] 3. This invention uses pre-embedded piles, which are buried in the ground. The mounting frame is then fastened to multiple pre-embedded piles using special bolts. This prevents the mounting frame from shaking in harsh environments, improves the stability and firmness of the mounting frame and the equipment installed on it, ensures the smooth operation of mortar production, and provides convenience for users.

[0026] 4. This invention, through the setting of a material distribution device, a workbench, and a second material supply pipe, connects one end of the second material supply pipe to the material distribution device and the other end to the sand processing device. After the material enters the material distribution device, it is fed into multiple second material supply pipes by the material distribution device, and then fed into the sand processing device for processing by the second material supply pipe, thereby improving the sand processing efficiency and providing convenience and assistance for users' work. In particular, users can operate the equipment while standing on the workbench, meeting the user's work needs.

[0027] 5. The present invention uses a feeding pipe to transport sand. The sand that is lifted up will enter the feeding pipe through a rotary feeding valve and then be guided into the distribution device. The distribution device will then distribute the sand to multiple sand processing devices to process the sand and provide convenience for users.

[0028] 6. The present invention features a liftable support, which is designed to automatically lift and lower the lifting device during maintenance and disassembly to meet the user's actual work needs and provide convenience for the user's maintenance and disassembly work.

[0029] 7. The present invention, through the setting of the bag dust collector interface, is used to connect and install the bag dust collector interface, and is used to collect the dust generated in mortar production and processing, so as to avoid the occurrence of a large amount of dust, ensure the quality of the production environment, meet environmental protection requirements, and improve the quality of the user's working environment.

Example

[0035] An adaptive fluidized dual-mode linkage vertical lifting mortar conveying device includes a mounting frame 1. A lifting pipe 2 is vertically fixedly mounted on one side of the mounting frame 1. Both sides of the lifting pipe 2 are connected to pneumatic manifolds 3. A microporous airflow liner 10 is vertically and equally spaced connected to one side of the pneumatic manifold 3 within the inner cavity of the lifting pipe 2. Uniformly distributed airflow holes 11 are opened on one side of the microporous airflow liner 10. A discharge chamber 7 is connected to the top of the lifting pipe 2. A rotary feed valve 4 is fixedly mounted on the top of the discharge chamber 7. The inlet end of the rotary feed valve 4 is connected to the discharge chamber 7. The bottom of one side of the lifting pipe 2... A rotary feed valve 2 is connected to the ground. The bottom end of the lifting pipe 2 is connected to a feed hopper 8 located on the ground. A fan 6 is connected to one side of the feed hopper 8. A chain conveyor belt 21 is fixedly installed inside the lifting pipe 2. A drive motor 9 is fixedly installed at the bottom of one side of the lifting pipe 2. The output shaft of the drive motor 9 passes through the interior of the lifting pipe 2 and is fixedly connected to the chain conveyor belt 21. A porous airflow distribution plate 22 is fixedly connected to the interior of the feed hopper 8. A controllable low-pressure air chamber is formed between the lower surface of the porous airflow distribution plate 22 and the inner wall of the feed hopper 8.

[0036] This invention has a revolutionary effect in reducing wear: the "air cushion" makes the sand material non-contact or lightly contact the wall surface, which solves the fundamental problem of the strong abrasiveness of dry sand and the life of key components is expected to be extended by 3 to 5 times. Significant energy savings: Due to the significant reduction in friction in the mechanical drive section, motor power consumption can be reduced by 30% to 50%, and the auxiliary air flow rate is much smaller than that of pneumatic conveying, resulting in a clear advantage in total energy consumption. Fully sealed, dust-free and environmentally friendly: The entire process from feeding to discharging is completely enclosed, combined with micro-dust removal, fully meeting stringent environmental protection requirements; Stable and adaptive operation: Through airflow regulation, it can adapt to fluctuations in sand particle size and moisture within a certain range, preventing material blockage or efficiency reduction; Easy to maintain: The structure is modular, with few vulnerable parts, mainly the chain plates, which are easy to replace.

[0037] The specific usage process is as follows: The core of this invention lies in "dual-mode linkage" and "adaptive fluidization". Dual-mode linkage: combining the low-speed, high-torque mechanical conveyor chain 21 with locally controllable airflow assistance, maximizing advantages and minimizing disadvantages. Adaptive fluidization: injecting a small amount of controllable airflow into the key feeding area and vertical lifting area, making the dry sand locally "quasi-fluidized", significantly reducing its internal friction and positive pressure on the equipment wall, thereby fundamentally reducing wear and energy consumption. It should be noted that the inside of the feeding hopper 8 is equipped with a porous airflow distribution plate 22, which has several airflow holes. A controllable low-pressure air chamber is formed below the porous airflow distribution plate 22. The air source is provided by a small Roots blower, that is, by the blower 6, and the pressure can be 5-15. Adjustable within the kPa range, and equipped with a rotary feed valve 5 at the feed inlet to ensure continuous feeding while maintaining airtightness and preventing backflow of airflow. It should be noted that the chain plates on the chain conveyor belt 21 can be designed as shallow cups or with transverse partitions to carry sand. The microporous airflow liner 10 is supplied with air through the air pressure manifold 3, and the microporous airflow liner 10 is laid along the inner walls of both sides of the lifting pipe 2. The introduced micro-gas seeps out from the micropores of the liner, forming an extremely thin "air cushion film" between the chain plate / sand and the pipe wall.

[0038] During operation, the drive motor 9 is started to drive the chain conveyor belt 21 to rotate inside the lifting pipe 2, conveying the sand fed by the rotary feed valve 25 upwards. Then, the belt turns at the top drive wheel, and the sand is thrown out by centrifugal force and gravity. The unloading chamber 7 expands to form a settling chamber, allowing the sand to naturally separate from the trace amounts of air it carries. The discharge port of the unloading chamber 7 is also equipped with a rotary feed valve to keep the system sealed, which is connected to the rotary feed valve 4 installed at the top of the unloading chamber 7. The side of the unloading chamber 7 is equipped with a bag filter interface to collect very little dust. It should be noted that the drive motor 9 is a variable frequency motor, which makes the conveying speed adjustable to control the lifting amount.

[0039] Furthermore, a pressure sensor and flow meter are installed on the outside of the lifting pipe 2 to monitor the pressure and flow rate of the air chamber and the air cushion of the lifting pipe. It should be noted that the entire lifting device is controlled by a PLC control system. The PLC control system automatically adjusts the fan frequency and airflow regulating valve according to the preset "sand lifting amount - optimal air cushion pressure" model to achieve self-adaptation. For example, when the lifting amount increases or the sand is slightly wet, the airflow pressure is automatically increased to maintain the optimal fluidization effect. Then, the sand enters the distribution device 13 through the feeding pipe 12. After passing through the distribution device 1... The 3-diverted material is fed into the sand processing device 15 for processing, and then discharged through the discharge pipe below the sand processing device 15 and conveyed by the conveyor belt to the next processing step, that is, the next processing step on the mortar processing system 20 that matches the sand processing device 15, until the finished mortar is produced. It should be noted that the mortar processing system 20 is existing technology, which includes the pre-processing and post-processing steps in this technical solution. This technical solution is arranged within the processing steps of the entire mortar processing system 20 to ensure the smooth progress of mortar production and processing.

[0040] The construction and assembly process of the lifting device is as follows: Phase 1: Basic Preparations and Component Prefabrication 1. Civil construction: According to the equipment general drawing, the inventor will pour mortar foundation, pre-embed anchor bolts, and reserve air intake pipes and cable conduits; 1. Component machining: 1.1.

[0041] Phase Two: On-site Installation 1. Main structure installation: 1.1. Starting from bottom to top, hoist the bottom feed hopper 8 in sequence, calibrate its level, and then fix it in place; 1.2. The segmented hoisting chain plate air cushion lifting pipeline shall ensure that the flanges are tightly sealed when connecting each segment, and that the manifolds of the internal airflow liner are accurately connected and connected with flexible hoses to ensure the verticality of the entire pipeline. 1.3 Install the top unloading hopper; 2. Internal mechanism installation: 2.1 Install the chain conveyor belt 21 inside the pipeline, connect the joint and tension it to a suitable degree; 2.2 Install the drive wheel assembly and drive motor at the top, and install the driven wheel and tensioning device at the bottom; 3. Auxiliary system installation: 3.1 Install the Roots blower and its inlet filter and silencer. Connect the blower 6 outlet to the bottom air chamber and the main pipe of the riser air pressure manifold 3 with a pipeline. Install the regulating valve and monitoring instruments on the main pipe. 3.2 Install rotary feed valve 1 (4) and rotary feed valve 2 (5) at the inlet and outlet; 3.3 Lay cables and connect all motors and sensors to the PLC control cabinet.

[0042] Phase 3: Debugging and Trial Operation 1. No-load commissioning: 1.1 Start the chain conveyor belt 21 and check whether it runs smoothly, whether there are any abnormal noises, and whether the tension is appropriate; 1.2 Start the Roots blower, gradually adjust the airflow in each branch, feel the airflow through the inspection port to see if the airflow from the liner is uniform, and check the system's sealing. 1.3 Test the PLC control system to verify whether the functions of motor start / stop, speed regulation, and air pressure follow-up regulation are normal; 2. Key steps in load debugging: 2.1. Turn off the airflow, add dry sand at a low flow rate, and observe the operating current, noise, and dust levels as a comparison benchmark; 2.2 Gradually activate and optimize the airflow assist system: The invention starts with low air pressure and gradually increases it while observing the effects; 2.3. Drive motor current: The invention objective is to demonstrate that the friction is reduced by significantly decreasing the current when the same lifting amount is achieved. 2.4 Equipment noise: The invention should significantly reduce noise; 2.5 Dust at the discharge port: The invention should be controlled to an extremely low level; 2.5. Through repeated debugging, the "optimal air cushion pressure value" under different lifting amounts was found, and this data model was solidified into the PLC program to achieve "adaptive" operation. 3. Acceptance and delivery: The invention will run continuously for 72 hours, and the improvement of various performance parameters, power consumption per ton, wear and tear, and dust concentration will be recorded.

[0043] In summary, the novel working concept and structure proposed in this invention, compared to the shortcomings of traditional dry sand vertical lifting technology such as high wear, high energy consumption, high dust, easy failure, and difficult maintenance, offers revolutionary wear reduction: the "air cushion" ensures that the sand material has non-contact or light contact with the wall surface, solving the fundamental problem of the strong abrasiveness of dry sand, and the lifespan of key components is expected to be extended by 3 to 5 times; significant energy saving: due to the significant reduction in friction, the motor power consumption of the mechanical drive part can be reduced by 30% to 50%, and the auxiliary air flow is much smaller than that of pneumatic conveying, resulting in a significant advantage in total energy consumption; fully sealed, dust-free and environmentally friendly: the entire process from feeding to discharging is fully enclosed, combined with micro-dust removal, fully meeting stringent environmental protection requirements; stable and adaptive operation: through airflow adjustment, it can adapt to fluctuations in sand particle size and moisture within a certain range, preventing material blockage or efficiency reduction; and simple maintenance: modular structure. This invention features a revolutionary reduction in wear: The "air cushion" design ensures the sand material is in non-contact or only slightly contact with the wall surface, solving the fundamental problem of the strong abrasiveness of dry sand. The lifespan of key components is expected to be extended by 3-5 times. Significant energy savings are achieved: The mechanical drive section experiences a substantial reduction in friction, reducing motor power consumption by 30%-50%. The auxiliary airflow is much smaller than that of pneumatic conveying, resulting in a clear advantage in overall energy consumption. It is fully sealed, dust-free, and environmentally friendly: The entire process from feeding to discharging is completely enclosed, combined with micro-dust removal, fully meeting stringent environmental requirements. Stable and adaptive operation is ensured: Airflow adjustment allows it to adapt to fluctuations in sand particle size and moisture content within a certain range, preventing blockages or efficiency reduction. Maintenance is simple: The modular structure minimizes wear, with the chain plate being the most vulnerable component, and replacement is convenient.

[0045] Specifically, the airflow holes 11 are set on the microporous airflow liner 10 and face the chain conveyor belt 21, so that the small amount of gas introduced can seep out from the airflow holes 11 and form an extremely thin "air cushion film" between the chain / sand and the pipe wall, reducing the wear of the sand on the pipe wall and extending the service life of the lifting device.
