[0002] my country currently has a considerable number of natural lake resources, with a total of 2,670 lakes with an area of ​​more than 1 square kilometer. The total area of ​​these lakes is vast, exceeding 80,700 square kilometers, and they constitute an indispensable part of my country's natural ecological structure. More importantly, some inland lakes are also the main source of domestic water for surrounding residents, so the management of lakes has great strategic significance for achieving sustainable development.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0046] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0047] like Figure 1-7 As shown, an automatic storage and batching system for flocculants for treating sewage on board a ship is provided as an embodiment of the present invention, including an unpacking and loading mechanism, a storage mechanism, a feeding mechanism, a metering mechanism, a stirring mechanism, a dust removal mechanism, an air path mechanism, an electronic control mechanism, a wind and rain sealing device 8 and a conveying mechanism 11.

[0048] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the unpacking and feeding mechanism includes:

[0049] Unpacking station 1 can unpack ton bags and send the materials to the sending tank 2 below. Unpacking station 1 is equipped with unpacking tools, manual inspection ports, screens, dust removal ports, and automatic doors. It has the basic functions of PAC / PAM ton bag unpacking, as well as dust removal and rainproof sealing functions to adapt to special working conditions on board. The inside of the equipment is kept dry, but due to the corrosion and water absorption of the raw materials, and the formation of colloids by water absorption, it is strictly forbidden to work on rainy days.

[0050] The sending tank 2 stores materials, and the materials are sent to the storage bin 4 for storage by compressed air.

[0051] A sending pipeline is a pipeline connecting the sending tank 2 and the storage bin 4.

[0052] 18.5kw pump provides the power source for delivery.

[0053] In the embodiment of the present invention, the WG5 horizontal feeder is an advanced pneumatic conveying device, which adopts fluidized pressure conveying technology, has a unique fluidized bed design and high blowing and unloading efficiency. It is suitable for conveying non-sticky or small granular materials such as cement, grain, fly ash, etc. The horizontal feeder has a large capacity, high volume utilization, convenient installation and adjustment, compact structure, light weight, easy operation, and convenient transfer; it is less restricted by terrain and is convenient for process layout. This equipment has been installed in advance and sent to the site. Attention should be paid to the on-site installation position and ladder connection position. The ladder and guardrail are connected by on-site grinding and welding.

[0054] This mechanism includes two feeding modes: manual and automatic. In the manual mode, the user can freely choose to add materials to the designated storage bin 4 to achieve designated feeding. In the automatic mode, the sending mechanism will automatically feed materials according to the material level mechanism in the storage bin 4.

[0055] The working process is as follows: the material is unpacked at the unpacking station 1, filtered through a screen and then enters the sending tank 2. The material in the sending tank 2 is sent into the storage bin 4 through the sending pipeline under the action of the pump.

[0056] like Figure 2 As shown, as a preferred embodiment of the present invention, the storage mechanism includes:

[0057] 8 independent storage silos (4 PAM silos, 4 PAC silos) are used to store materials. A single storage can support the continuous operation of the entire equipment for one week, ensuring production continuity.

[0058] The high and low material level prompt device is used to remind the operator to add material and participate in the automatic control to realize the automatic feeding function. Two long rod material level meters 13 are arranged on the top and used in parallel to monitor the material height in the silo to prevent the unknown full material situation caused by malfunction and cause the silo to explode.

[0059] The vibration motor 12 is arranged in the storage bin 4 to prevent the materials from bridging and arching.

[0060] In the embodiment of the present invention, the storage mechanism can realize the function of real-time monitoring of the inventory status of the material inside the silo according to the preset value and the metered batching value.

[0061] The working process is as follows: the material is sent to the storage bin 4 for storage. The high and low material level prompt device in the bin will issue prompts according to the material inventory, and the vibration motor 12 will work regularly to prevent material bridging. The long rod material level meter 13 monitors the material level in real time to ensure that the bin will not burst due to full material.

[0062] like Figure 2As shown, as a preferred embodiment of the present invention, the feeding mechanism comprises:

[0063] 12 screw conveyors 6, the feed port of the screw conveyor 6 is connected to the storage bin 4 with bolts through a flange, the pixel plate is sealed inside, and the discharge port of the screw conveyor 6 is connected to the metering hopper 7 through a flexible connection. It is used to evenly feed the material from the storage bin 4 into the metering hopper 7 to ensure accurate metering; each screw conveyor 6 is equipped with a screw.

[0064] The pneumatic butterfly valve 14 is installed at the discharge port of the screw conveyor 6 to seal the discharge port and prevent material leakage.

[0065] In the embodiment of the present invention, the motor drives the rotating spiral body (blade) enclosed in the circular steel pipe through the reducer to achieve rapid feeding during weighing. The screw conveyor 6 is used to convey powder, small particles or flake materials.

[0066] The working process is as follows: the screw conveyor 6 conveys the material in the storage bin 4 to the measuring hopper 7 through the screw. During the conveying process, the pneumatic butterfly valve 14 ensures the sealing of the discharge port to prevent material leakage.

[0067] like Figure 2 and Figure 5 As shown, as a preferred embodiment of the present invention, the metering mechanism includes:

[0068] Rack for support.

[0069] The metering hopper 7 is used to load and measure materials. The metering hopper 7 is welded by steel and plate. The metering hopper 7 uses a stainless steel spiral discharger. The 8 sets of metering hoppers 7 can work independently, and several of them can be specified to start working according to needs. The top of the metering hopper 7 is connected to the pneumatic butterfly valve 14 through a soft connection, and the spiral outlet below the metering hopper 7 is connected to the mixing tank 18 through a soft connection, and the outlet is provided with a discharge valve 17.

[0070] The sensor 15 is used to detect the weight of the material and convert it into a standard signal. The required material is accurately measured through the weight sensor 15, and the discharge screw 16 at the outlet of the measuring bucket 7 is controlled by frequency conversion to achieve uniform and uniform unloading, ensuring the mixing effect of the stirring tank 18 at the rear. In the working state, each measuring bucket 7 is fixed on the frame through three pressure sensors 15. The signal sent by the sensor 15 is processed and sent to the signal processor in the main control room, and then converted into a standard signal and transmitted to the touch screen to display the material weight value; in the transportation state, the sensor 15 box is loaded to the construction site, and the bracket and the measuring bucket 7 are transported to the construction site separately.

[0071] Discharge valve 17 controls material output.

[0072] Vibrator to ensure even distribution of material during metering.

[0073] In the embodiment of the present invention, the metering mechanism is a weight loss weighing mechanism, which can deliver the material in the metering bucket 7 at a uniform speed through an algorithm to ensure that the difference between the initial state material weight and the final state material weight is the formula weight, and can control the delivery time through frequency modulation to ensure that the required material is weighed within the required time range. PAC200-300kg / h, PAM20-60kg / h. The specific formula and delivery time can be set.

[0074] The metering mechanism can store 400L of material, realizing the function of single-time feeding and multiple metering. When the remaining value of the material in the bucket is less than that of a single formula, the screw conveyor 6 is started to add material to the metering bucket 7. When the material reaches the set high value, it stops and the cycle is carried out.

[0075] The working process is as follows: the material is fed into the measuring hopper 7, the sensor 15 detects the weight of the material and converts it into a standard signal, which is displayed on the touch screen. According to the formula requirements, the discharge valve 17 and the vibrator are controlled to achieve accurate measurement and uniform discharge of the material.

[0076] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the stirring mechanism includes:

[0077] The stirring tank 18 is used to mix the material and water.

[0078] Sludge pump is used to pump the mixed material to the curing tank.

[0079] Curing pool, used for curing materials.

[0080] In the embodiment of the present invention, the working process is as follows: the weighing bucket 7 discharges the weighed material into the mixing tank 18, and at the same time adds an appropriate amount of water for stirring. After the stirring is completed, the material is pumped into the curing tank for curing by the sludge pump.

[0081] The system process is: storage area → crane → unpacking station 1 → sending tank 2 → storage bin 4 → screw conveyor 6 → measuring hopper 7 → discharging screw 16 → mixing tank 18. The material is sent from the storage area to the top of the unpacking station 1 by the customer's crane, and enters the sending tank 2 after unpacking. The sending tank 2 sends the material to the storage bin 4 through the pipeline. The bottom of the storage bin 4 is provided with a screw conveyor 6, which is sent to the measuring hopper 7 through the screw conveyor 6. The discharging screw 16 is provided below the measuring hopper 7, and the material can be sent to the mixing tank 18 (prepared by the customer) below through frequency conversion.

[0082] like Figure 1-4 As shown, as a preferred embodiment of the present invention, the dust removal mechanism includes:

[0083] The unpacking dust collector 3 can recycle the dust generated during the unpacking process to keep the environment clean.

[0084] The dust collector 5 on the top of the silo removes and recycles the materials when they enter the storage silo 4 to prevent dust pollution.

[0085] Dust removal pipeline connects the dust collector and the dust removal point.

[0086] In the embodiment of the present invention, the material in the sending tank 2 is sent to the storage bin 4 through the sending pipeline under the action of the pump, and the unpacking dust collector 3 works to recover the generated dust. Workflow: The dust generated during the unpacking, sending, storage, etc. is sucked into the dust collector through the dust removal pipeline for treatment to prevent dust from polluting the environment.

[0087] like Figure 2 As shown, as a preferred embodiment of the present invention, the gas circuit mechanism includes:

[0088] The 7.5kw air compressor 10 is used to provide a 0.5-0.8mPa compressed air source for the control mechanism.

[0089] Tight filter and air source triplex, used to purify compressed air.

[0090] Pipelines and solenoid valves are used to control the flow direction of the gas line.

[0091] Pneumatic actuators are used to drive actuators such as cylinders.

[0092] In the embodiment of the present invention, the batching branch air circuit is composed of multiple cylinders, and the batching is realized by controlling the opening and closing of the material door through the cylinder. The dust collector controls the compressed air to backflush through the pulse solenoid valve to ensure the self-cleaning of the filter bag.

[0093] Working process: The compressed air generated by the air compressor is filtered and purified, and then transported to each component that requires an air source through pipelines and solenoid valves.

[0094] like Figure 1 As shown, as a preferred embodiment of the present invention, the electric control mechanism 9 is the overall automatic control mechanism of the whole set of equipment, which is controlled by the PLC program to realize the automatic operation of the equipment. There are two control modes for electrical control, both of which can complete production independently. One mode is for the operator to manually operate the relevant buttons to complete production; the other mode is to realize automatic production and management by controlling the touch screen and the operating table. The two control modes can be converted to each other. Another mechanism can communicate and interconnect with the master control mechanism to realize automatic intelligent management.

[0095] like Figure 2 and Figure 3As shown, as a preferred embodiment of the present invention, the weatherproof sealing device 8 is used to seal the metering hopper 7, isolate the deck and the cabin, and meet the weatherproof sealing requirements.

[0096] like Figure 4 As shown, as a preferred embodiment of the present invention, the conveying mechanism 11 is controlled by pipeline valve interlocking, and can load materials into any designated storage bin 4, thereby optimizing equipment and space utilization.

[0097] The working principle of the present invention is:

[0098] The automatic storage and batching system for flocculants used for sewage treatment on board ships has the following working process:

[0099] Step 1: Positive pressure feeding;

[0100] (1) Detect the status of unpacking station 1: Detect the door opening limit of unpacking station 1. If it is open, execute the sending mechanism operation; otherwise, display the standby state.

[0101] (2) Feeding operation: Press the feed button, open the exhaust valve (220v) and the feed valve (220v) to feed. After the feeding is completed, press the feed completion button and close the feed valve and the exhaust valve.

[0102] (3) Sending materials: Press the No. 1 send button to send materials to the PAM silo. Press the No. 2 send button to send materials to the PAC silo.

[0103] (31) Confirm that the air inlet valve 1 and the air inlet valve 2 are in the open position, and the secondary air supply valve and the discharge valve are in the closed position.

[0104] (32) After the feed valve (220v) and the exhaust valve are closed at the same time, start the motor (18.5kw).

[0105] (33) When the pressure in the tank rises to 0.17Mpa, open the secondary air supply valve (220V) and start the discharge valve (220v)

[0106] (34) When the discharge valve is opened, the corresponding silo pipeline valve (Dc24v) is opened at the same time. At the same time, the corresponding silo valve is started.

[0107] All of the above can be switched to manual control for maintenance operations.

[0108] Note: There are two sets of sending pipelines for sending tank 2. When the No. 1 sending button is selected, the PAM pipeline unloading valve opens. When the silo reaches the high material level, the reversing valve is used to switch the valve, and the No. 1, 2, 3, and 4 silos are loaded in turn. When the No. 4 silo reaches the high material level, the delayed sending is completed to send tank 2 and the remaining materials in the pipeline. When the No. 2 sending button is selected, the PAC pipeline unloading valve opens, and the corresponding silo pipeline valve opens, and the silos 5 to 12 are loaded in turn. When the last sending of the No. 12 silo is completed, the sending tank 2 and the remaining materials in the pipeline can be opened for loading of other silos that have not reached the high material level. Among them, No. 1, 2, 3, and 4 silos each have a silo top dust collector 5. When the corresponding silo is sent, the respective dust collectors are opened. After the corresponding silo stops loading, the dust collector is delayed to stop and backflush. Silos 5 and 6 are connected and share the same dust collector 5 on the silo top; silos 7 and 8 are connected and share the same dust collector 5 on the silo top; silos 9 and 10 are connected and share the same dust collector 5 on the silo top; silos 11 and 12 are connected and share the same dust collector 5 on the silo top.

[0109] The feeding system has the function of manual pipeline cleaning, and all valves can be opened to clean the residual materials.

[0110] Step 2: Measuring and conveying;

[0111] (1) Initial feeding: Set the initial feeding value of the metering hopper 7 and start the screw conveyor 6 to feed the metering hopper 7. When the metering hopper 7 reaches the initial value, stop feeding and prepare for metering.

[0112] Set the initial feeding value of the metering hopper 7. A screw conveyor 6 (4kw) is provided under the PAM silo to feed the metering hopper 7. Each PAM silo corresponds to a PAM weight loss scale 19. A screw conveyor 6 is provided under every two PAC silos, corresponding to a PAC weight loss scale 19. When feeding, only one screw conveyor 6 (4kw) is used. If the low material level alarm is sounded above the corresponding screw conveyor 6, switch to another screw conveyor 6 (5.5kw). The hopper is equipped with a vibration motor 12 to assist the flow. If the initial value is set, the metering hopper 7 must reach the initial value before each batching before it can be used. For example, if the initial value of the No. 1 metering hopper 7 is set to 80kg, when the metering hopper 7 is lower than 80kg, the corresponding screw conveyor 6 is started to feed, and it stops when it reaches 80kg. That is, the initial state preparation is completed.

[0113] (2) Accurate metering: According to the formula setting, the speed of the screw conveyor 6 is adjusted by frequency conversion to achieve uniform unloading. During the metering process, the weight of the material is monitored in real time by the weight sensor 15 to ensure accurate metering.

[0114] According to the initial setting, the screw conveyor 6 (1.1kw) under each silo is adjusted to high speed (0-50hz adjustable) or high speed (0-50hz adjustable and lower than high speed) by frequency conversion.

[0115] For example, if the formula of the No. 1 silo scale is set to 50kg, 10min, the default high speed is 10Hz, and the low speed is 5Hz for 5kg, then through the reduction calculation, if it is less than 5kg in 1 minute, the conveying speed will be increased, and if it is greater than 5kg, the conveying speed will be reduced to ensure the conveying time, and the outlet discharge valve will be closed. There are 8 sets of weight loss scales 19.

[0116] (3) Mixing and conveying: The metered materials are mixed and blended in the mixing tank 18, and then pumped into the curing tank for curing.

[0117] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
