Description

Shipborne concrete production system and method Technical Field

[0001] The invention belongs to the technical field of water concrete mixing and relates to a shipborne concrete production system and method. Background Art

[0002] Continuous concrete production and environmental protection are crucial factors in underwater concrete pouring. For concrete production facilities located on land, transporting concrete over long distances significantly reduces the economic efficiency of concrete pouring. This disadvantage is particularly prominent in projects involving small, dispersed volumes of concrete, such as bridge piers.

[0003] In the prior art, some inventors have designed concrete mixing ships. For example, Chinese patent application CN 104260209 A proposes a mobile concrete mixing ship for inland waterways. This patent improves the balance of the ship by adjusting the position and spatial layout of the installation equipment. However, it does not consider how to maintain the balance of the ship during the dynamic process of loading and production. It also does not take into account the dredging function and the use of dredged materials to produce sand and gravel and production water. In addition, this concrete mixing ship does not consider waste treatment. The production and domestic sewage on the concrete mixing ship seriously pollutes the water body, which is easy to cause ecological damage and impact.

[0004] Summary of the Invention

[0005] To address the issues raised in the background art, the present invention provides a shipboard concrete production system that solves at least one of the technical problems mentioned in the background art. By zoning the ship's hull according to its functional characteristics, a shipboard concrete production system integrates stone collection, stone crushing, aggregate screening, fine aggregate production, sewage treatment, concrete mixing, and concrete transportation. Cement, fly ash, and dry admixture powders are pre-loaded into storage areas at the port for ready use. Mixing water, coarse aggregate, fine aggregate, and other raw materials are then produced and prepared by the shipboard system.

[0006] This invention utilizes local river stones and water for processing, resolving the aggregate and water sourcing issues during concrete production. This enables continuous, streamlined concrete production, significantly reducing the costs of aggregate transportation and concrete mixing system construction. Furthermore, the invention utilizes sensors and a balancing water tank to achieve automatic hull balancing, effectively addressing the instability issues associated with multi-zone material allocation.

[0040] As shown in Figures 1 to 5, Figure 2 adopts a pump turntable material distribution method. The arrows in the figure indicate the transportation direction of the material during the production process. An embodiment of the present invention provides a ship-borne concrete production system, including a hull 1, which includes a storage cabin 2, a stone collection subsystem 3, a stone crushing subsystem 4, a fine aggregate processing subsystem 5 and a concrete mixing subsystem 6.

In the description of the present invention, the lower end refers to the side that is located downstream in the material processing order according to the production link; wherein

[0041] The stone collection subsystem 3 includes an air compressor 31, an air pipe 32, a cutter suction device 33, a single-arm rotary crane 34, a stone suction pipe 35 and a filter screen 36. The air compressor 31 forms negative pressure gas through the air pipe 32 and then passes it through the cutter suction device 33. The single-arm rotary crane 34 uses a cable to lift the cutter suction device 33 to adjust the range of stone and river water collected by the cutter suction device 33. One end of the stone suction pipe 35 is connected to the cutter suction device 33, and the other end is connected to the filter screen 36; the front end of the cutter suction device 33 is connected to a large-pore steel filter for filtering branches and other solid waste. The equipment 33 generates power by rotating to suck up stones and river water. The range of the stone and river water collected by the suction equipment 33 can be adjusted through the single-arm rotary crane 34, and the construction can be flexibly adjusted to ensure the supply of raw materials and construction efficiency. The stone and river water enter the stone suction pipe 35 through the suction equipment. The end of the stone suction pipe 35 is connected to the filter screen 36 to achieve preliminary screening of the stone. After screening, the stone that does not meet the particle size requirements is discharged into the waste bin 21 through the waste pipe 37, and the stone that meets the particle size requirements and an appropriate amount of river water enter the stone crushing subsystem 4 through the pipeline. The excess river water is discharged into the river channel through the pipeline.

[0042] The stone crushing subsystem 4 comprises, from top to bottom, a crushing device 41, a screening device 42, and a feed hopper 43. The outlet of the stone suction pipe 35 leads to the crushing device 41. Stone and a suitable amount of river water enter the crushing device 41 through the end of the filter screen 36 of the stone collection subsystem 3. After crushing, they enter the screening and dewatering equipment below. The screened aggregate and wastewater pass through the feed hopper and enter the sedimentation tank, the coarse aggregate silo, and the fine aggregate processing system 5, respectively. All equipment is connected by pipelines, and the processed products are transported to other equipment or silos primarily by gravity. The entire process takes place within a closed space, and wet crushing and screening are performed. Wastewater is treated for secondary use or discharged into the river, eliminating the generation of pollutants such as dust and wastewater.

[0043] The fine aggregate processing subsystem 5 comprises, arranged from top to bottom, a sand making device 51, a sand washing device 52, and a dewatering device 53. Located below the screening device 42 of the stone crushing subsystem 4, the fine aggregate processing subsystem 5 is used to further process the crushed coarse aggregate through the sand making device 51 to form fine aggregate. The fine aggregate processing subsystem 5 also includes a water pump 54 and a pipeline 55. These pumps 54 and pipelines 55 are connected to pump clean water into the sand washing device 52 for sand washing. After sand washing, the fine aggregate is dehydrated by the dewatering device. The sand and wastewater flow through pipelines into the fine aggregate silo and sedimentation tank, respectively. A belt conveyor is installed between the fine aggregate processing subsystem and the stone crushing system to transport oversized aggregate to the stone crushing subsystem for secondary processing. The belt conveyor is equipped with a sealed protective cover to ensure that the aggregate is transported within a confined space.

[0044] The concrete mixing subsystem 6 includes a mixing station 61, a raw material conveying pipeline 62 and a raw material conveying equipment 63, wherein the raw material conveying equipment includes a belt conveyor 631 and a bucket elevator 632, a water pump 64 for adding water and a water adding pipe 65 connected to the water pump. Coarse aggregate and fine aggregate are respectively transported to the end of the aggregate conveying channel by the belt conveyor at the bottom of the silo, and then vertically transported by a bucket elevator feeder. Finally, they enter the concrete mixing station through a pipeline. The water for concrete mixing is pumped from the clean water tank to the mixing station by a water pump. Fly ash and cement are respectively transported vertically from the fly ash silo and cement silo to the mixing station by bucket elevator feeders. Bucket elevator feeders can save feeding space compared to feeding belts. All raw material transportation pipeline outlets are equipped with electronic metering equipment or a bucket weighing system is equipped in the mixing station 61 to ensure that the mix ratio of concrete meets the usage requirements. After all raw materials are transported to the mixing station, the mixing station mixes and produces concrete, and the produced concrete enters the clinker hopper at the bottom of the mixing station. The arc gate at the bottom of the clinker hopper is connected to the pump hopper through a chute.

[0045] In another embodiment, based on the above embodiment, referring to Figure 2, the storage tank 2 is arranged under the deck, and the storage tank 2 includes a waste bin 21, a fine aggregate bin 22, a graded coarse aggregate bin 23, a water purification pool for domestic and production water 24, a fly ash bin 25 and a cement bin 26. The waste bin 21, the fine aggregate bin 22, the graded coarse aggregate bin 23, the water purification pool for domestic and production water 24, the fly ash bin 25 and the cement bin 26 are symmetrically distributed on both sides of the hull. The layout positions of the above 6 bins are determined according to the positions of the subsystems of the ship-borne concrete production system, and the layout positions of each subsystem can be appropriately adjusted according to the ship type and the equipment size of the production system.

[0046] In a preferred embodiment, referring to Figure 2, it also includes a hull automatic balancing subsystem 7, which includes a hull partition balancing water tank 71, which is distributed around and on the bottom of the hull and is divided into multiple small water tanks according to the hull. It also includes a level sensor installed on the hull, a control main board, and an automatic water pump arranged in each hull partition balancing water tank 71, one end of the automatic water pump is connected to the bottom of the hull partition balancing water tank 71, and the other end is connected to below the water surface of the river. The level sensor and the automatic water pump are electrically connected to the control main board respectively, and the level sensor is used to transmit the hull stability information to the control main board in real time. When the level sensor value exceeds the preset threshold, the control main board will automatically calculate the water filling or drainage of the hull partition balancing water tank, and then start the automatic water pump to fill or drain water to the specific hull partition balancing water tank.

[0047] In another preferred embodiment, referring to FIG3 , a conveying subsystem 8 is further included. The conveying subsystem comprises a concrete pump 81, a turntable 82, and a pump pipe 83. The conveying subsystem 3 is configured to, after finished concrete enters the concrete pump 81 through the chute, use the variable-amplitude pump pipe 83 to achieve variable-amplitude and steerable feeding under the rotation of the turntable 82, thereby meeting the distribution needs of different locations. Alternatively, the conveying subsystem 3 is configured to, after finished concrete enters the concrete pump 81 through the chute, use the variable-amplitude pump pipe 83 to achieve variable-amplitude and steerable feeding under the hoisting of a single-arm slewing crane 34, thereby meeting the distribution needs of different locations.

[0048] In another preferred embodiment, it also includes a water purification subsystem 9, which includes a sedimentation tank 91, a water purification device 92 connected to the sedimentation tank, and a control main board 94. The sedimentation tank 91 includes a coagulation tank 911, a sedimentation tank 912 and a filter box 913. The water purification device 92 is connected to the lower end of the filter box 913. Flow monitoring instruments 95 are installed at the inlet of the coagulation tank 911 and the inlet of the water purification device 92, and a water quality detection instrument 96 is installed in the water purification device; it also includes a fully automatic dosing device 93 for adding reagents to the coagulation tank and the water purification device, and the flow detection instrument 95, water quality detection instrument 96 and fully automatic dosing device 93 are electrically connected to the control main board 94 respectively.

[0049] In other preferred embodiments, a ship system 10 is also included. This system comprises engine room power equipment 101, living quarters 102, and tool rooms 103. This system is a general purpose system that provides basic functions such as ship power and crew living. Domestic sewage from living quarters 102 is discharged into a domestic sewage tank 104. The crew's daily drinking water is purified by a direct drinking water dispenser. Since domestic wastewater is relatively small, it is collected by discharging it into the domestic sewage tank and transported to a sewage treatment plant for treatment after docking via a dedicated vehicle. The ship system also provides power for the entire onboard concrete production system.

[0050] In the above embodiment, the fully automatic dosing device 93, the water quality monitoring instrument 95 and the control mainboard 94 are integrated into the water purification equipment 92, and its main working principle is as follows:

[0051] The wastewater from the stone crushing and sand washing process first enters the sedimentation tank 91 for pretreatment. The sedimentation tank 91 is divided into three boxes, namely the coagulation box 911, the sedimentation box 912 and the filter box 913. A flow monitoring instrument 95 is installed at the entrance of the coagulation box 911. According to the flow rate, the full-automatic dosing device 93 automatically calculates the amount of water purifier to be added, and adds it to the coagulation box 911 at a regular and quantitative time. After the wastewater is mixed in the coagulation box 911, the colloid and suspended matter form large-particle flocs that are easy to precipitate. Then the wastewater enters the sedimentation tank 912, and the large-particle flocs and sediment are precipitated. Finally, it enters the filter box 913 for filtration. After filtering out the sediment, suspended matter and colloidal substances in the wastewater, it flows into the water purification equipment 92.

[0052] A flow monitoring instrument 95 is set at the inlet of the water purification equipment 92. After the water enters the water purification equipment 92, the water quality monitoring instrument 96 dynamically monitors the water quality, mainly detecting indicators such as pH value, chloride ion, sulfate ion, and alkali content. The detection results of the water quality monitoring instrument 96 are transmitted to the control main board 94. Concrete production personnel can set the monitoring indicator range according to the concrete production type through the control main board 94. The control main board 94 analyzes the indicators of the concrete water standard according to the preset indicator values. If the indicators exceed the water standard, the water inlet flow of the equipment and the water quality monitoring indicator value are automatically calculated to calculate the concentration of the added agent, and the configuration information is transmitted to the full-automatic dosing device 93. The full-automatic dosing device 93 configures the agent according to the agent concentration ratio, and automatically adds it to the water purification tank at a fixed time and quantity to mix with the wastewater. After the reaction, the wastewater is filtered once and flows into the domestic and production water purification pool 24 through a pipeline for use.

[0053] The coagulants, filter aids, acid and alkali solutions, calcium chloride, calcium bicarbonate, disinfectants and other chemicals required for wastewater treatment are provided by a fully automatic dosing device 93. This equipment is controlled by a PLC, and the control cabinet is equipped with functions such as low liquid level pump stop, metering pump and mixer mechanical failure sound and light alarms. It can not only prepare solutions, but also quantitatively and regularly add chemicals.

[0054] In another preferred embodiment, the storage tanks 2 are symmetrically distributed on both sides of the hull 1, and the stone collection subsystem 3, the stone crushing subsystem 4, the fine aggregate processing subsystem 5 and the concrete mixing subsystem 6 are installed on the long axis a of the hull. On the one hand, this allows the installed equipment on the hull 1 to be in a static equilibrium state, and on the other hand, it allows sufficient space on the deck 11 of the hull 1 for on-site production and for operators to carry out dressing operations.

[0055] The shipborne concrete production method of the above embodiment, referring to Figures 1 to 5, comprises the following steps:

[0056] Step 1: Start the hull automatic balancing subsystem 7 to maintain balance during loading and load sufficient cement, fly ash and admixtures;

[0057] Step 2: The boat is driven to the predetermined location and moored. The stone collection subsystem is activated to collect stone 3, or stone is collected while the river sediment is being cleared. After preliminary screening by the filter screen 36, qualified stone enters the stone crushing subsystem 4, and unqualified stone enters the waste bin 21;

[0058] Step 3: Start the stone crushing subsystem 4 to crush and screen the qualified stones. After dehydration, the qualified aggregate enters the coarse aggregate bin 23. According to the required amount of fine aggregate, part of the coarse aggregate is returned to the stone crushing subsystem 4 for re-crushing to form finer aggregate. The finer aggregate enters the fine aggregate processing subsystem 5 for further crushing or rod grinding. After crushing or rod grinding, it is screened and dehydrated. The qualified fine aggregate enters the fine aggregate bin 22, and the wastewater flows into the water sedimentation tank 91.

[0059] Step 4: The sewage in the sedimentation tank 91 is filtered and precipitated step by step through the coagulation tank 911, the sedimentation tank 912 and the filter tank 913. During the process, water purifier is added in proportion to promote the precipitation and filtration of impurities such as sediment, suspended matter and colloid in the water. The timing and dosage of adding the water purifier are automatically calculated by the system program based on the automatic detection of the water quality detection instrument 96, and the configuration information is then transmitted to the fully automatic dosing device 93. The automatic dosing device 93 automatically configures the agent according to the program, and automatically adds it to the water purification tank at a fixed time and quantity to mix and stir with the sewage. The treated clean water flows into the water purification tank for standby use;

[0060] Step 5: Concrete mixing. Start the belt conveyor 631 at the bottom of the coarse aggregate silo 23 and the fine aggregate silo 22. The aggregate is transported to the bucket feeder 632 through the belt conveyor 631. The bucket feeder 632 then vertically transports the aggregate through the raw material conveying pipe 62 into the concrete mixing station 61. The water for concrete mixing is pumped from the domestic and industrial water purification tank 24 to the mixing station 61 through a water pump. The fly ash and cement are respectively transported vertically from the fly ash silo 25 and the cement silo 26 to the mixing station 61 through the bucket feeder 632 to complete the concrete mixing.

[0061] Preferably, during step 1 to step 5, the hull automatic balancing subsystem 7 is always started to automatically monitor the balance of the hull 1, and the level sensor 12 transmits the stability information of the hull 1 to the control main board 13 in real time. When the value of the level sensor 12 exceeds the preset threshold, the control main board 13 automatically calculates the water filling or drainage volume of the hull partition balancing water tank 71, and starts the automatic water pump 72 to fill water or drain water to the specific hull partition balancing water tank 71 to always maintain the balance of the hull 1.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
