Description

Technical Field

[0002] Currently, specialized dry bulk cargo terminals in China, such as Qinhuangdao Port, primarily focus on coal transportation. Due to the open-air storage of coal, dust inevitably arises during storage and transfer. Combined with factors such as water spraying and rainfall, this generates large quantities of coal sludge water. To centrally process and collect the coal sludge, several sedimentation tanks have been constructed near the coal storage yards to centrally settle and clean the sludge water. Currently, ports treat the sludge water in these tanks using either a combination of mobile machinery and manual labor, or a combination of vacuum trucks and manual labor. These existing methods are inconsistent, costly, and highly susceptible to secondary contamination of the road surfaces adjacent to the coal sludge tanks, negatively impacting the port's environmental image. To avoid the secondary contamination, inefficiency, and inability to recycle the road surface caused by mobile machinery or vacuum trucks, a treatment device is needed that can continuously collect the sludge water. The treated sludge water can then be separated into coal cakes and separated water, with the cakes then recycled and the separated water used for road sprinkling. Utility Model Content

[0024] The structure of the present invention will be further described below with reference to the accompanying drawings and through examples. It should be noted that the present examples are descriptive rather than restrictive.

[0025] A mobile coal slime recovery and processing device with automatic stirring function, see Figure 1-Figure 5 , including a mobile transportation part 1, an automatic stirring part 2, a feeding part 3, a dehydration and pressing part 4, and a discharge part 6.

[0026] The mobile transport part includes: a vehicle head 1.1 and a flatbed vehicle 1.2. The vehicle head is connected to the flatbed vehicle to provide mobile transport.

[0027] The automatic mixing unit includes a mixing pump 2.11 and a lifting device. The lifting device utilizes a rotatable, telescopic cantilever structure, comprising a column 2.1, a first cantilever 2.3, a second cantilever 2.6, a tie rod 2.4, an electric hoist 2.7, a pump bracket 2.9, a feed front pipe 2.10, a rotary drive mechanism 2.2, a telescopic drive mechanism 2.5, and a motor bracket 2.12. The lower end of the column is vertically fixedly connected to the gooseneck of the flatbed truck. The first cantilever is a square tube, one end of which is rotatably attached to the column, and the other end of which is relatively movable and pluggable with the second cantilever. One end of the tie rod is hingedly connected to a first tie rod seat fixed to the first cantilever, and the other end of the tie rod is hingedly connected to a second tie rod seat rotatably mounted on the column. This creates a triangular connection between the column, first cantilever, and tie rod, ensuring a secure connection between the first cantilever and the column. The motor bracket is fixedly connected to the column and is provided with a motor mounting base. The rotary drive mechanism includes a rotary drive motor 2.2.1, a first rotary drive gear 2.2.2, and a second rotary drive gear 2.2.3. The rotary drive motor is fixedly mounted on a motor mounting platform. The first rotary drive gear is drivingly connected to the output of the rotary drive motor. The second rotary drive gear is coaxially integrally mounted on the column or coaxially fixed to the column and meshes with the first rotary drive gear. The telescopic drive mechanism includes a telescopic drive motor 2.5.1, a telescopic drive gear (not shown in the drawings), and a telescopic drive rack 2.5.2. The telescopic drive motor is fixedly mounted on the outside of the first cantilever. The telescopic drive gear extends into the interior of the first cantilever through a slot provided in the first cantilever and is drivingly connected to the output of the telescopic drive motor. The telescopic drive rack is fixedly mounted on the second cantilever along the length of the arm and meshes with the telescopic drive gear. The electric hoist is connected to the outer end of the second cantilever via a hook. The rope end hook of the electric hoist is connected to the upper end of the pump bracket via a suspension rope 2.8. The pump bracket consists of an upper mounting platform and four support legs. The stirring pump is fixedly connected to the lower side of the upper mounting platform of the pump bracket, and the front end pipe of the feed is vertically fixedly connected to the upper mounting platform.

[0028] When the automatic stirring part is used, when stirring is required, the first cantilever and the second cantilever are rotated to the position in front of the column under the action of the rotary drive mechanism, and the pump bracket is stably placed on the front end of the gooseneck of the flatbed truck by controlling the zipper length of the electric hoist; and when stirring operation is required, the device is moved as a whole to one side of the coal slime sedimentation tank through the mobile transport part, and then the rotary drive motor is started to make the automatic stirring part rotate around the column to the top of the coal slime sedimentation tank, and then according to the distance between the coal slime sedimentation tank and the device, the telescopic drive motor is started, the extension length of the second cantilever is adjusted, and the stirring pump is adjusted to the appropriate position relative to the coal slime sedimentation tank, and then the electric hoist is started to sink the pump bracket, the stirring pump and the front end pipe of the feed to the appropriate depth position in the coal slime sedimentation tank, and then the stirring pump is started to stir the coal slime water, and when the suspension is reached, the rear feeding part can be opened for feeding.

[0029] The feed section is mounted on a flatbed truck behind the automatic mixing section and primarily comprises a feed pump 3.2, a feed pipeline 3.1, and a discharge pipeline 3.3. The feed pumps are plunger pumps, two of which are arranged side by side and alternately operate via a pump station 3.4 and a control valve block 3.5. Both the pump station and the plunger pumps are equipped with a water cooling system for cooling. The feed pipeline utilizes a main pipe and two branch pipes. The main pipe's end is fixedly connected to one end of a feed hose via a flange, while the other end of the feed hose is fixedly connected to the upper end of the feed front pipe, transporting the coal slurry. The ends of the two branch pipes are fixedly connected to the inlets of the two feed pumps via flanges. The discharge pipeline also utilizes a two-branch pipe-main pipe connection. The ends of the two branch pipes are fixedly connected to the outlets of the feed pumps via flanges. The main pipe is connected to the inlet of the filter press pump in the rear dewatering and squeezing section via pipeline 3.6, transporting the coal slurry to the rear dewatering and squeezing section.

[0030] The dewatering and squeezing section is installed on a second-floor platform behind the feed section and primarily comprises a squeezing pump 4.1, a filter press 4.2, a control cabinet 4.3, and a power distribution cabinet 4.4. The filter press is controlled by the control cabinet. Coal slurry enters the filter press through the squeezing pump, where it is squeezed to separate the solid and liquid, forming coal cakes and water. The power distribution cabinet provides power to the entire system. The dewatering and squeezing section can be designed based on existing structures.

[0031] The discharge section, mounted above a flatbed truck behind the feed section and located below the second-floor platform 5, primarily comprises a belt conveyor and a drainage pipe. The belt conveyor transports the coal cakes separated by the filter press to the rear of the system for accumulation. The drainage pipe, connected to the drain outlet at the bottom of the filter press, conveys the water separated by the filter press to a sewage tank.

[0032] The operating method of the mobile coal slime recovery and processing device with automatic stirring function is as follows:

[0033] Step 1: Drive the device to one side of the coal slime sedimentation tank 13 via the vehicle head, and place the stirring pump into the coal slime water via the lifting device;

[0034] Step 2: Turn on the stirring pump to fully stir the coal slurry water into a suspension, and turn on the feed pump to extract the coal slurry water;

[0035] Step 3: Turn on the filter press through the control cabinet. The coal slurry in the sedimentation tank is fed into the filter press under the pressure of the feed pump. When the feed pump pressure reaches the set pressure range, the pressure is maintained and the feed is fed. During the feeding process, the feed pressure and the discharge condition are observed and the feed is stopped.

[0036] Step 4: Start the squeezing pump and gradually increase the pressure. The coal cake in the filter chamber of the filter press is affected by the expansion of the diaphragm filter plate, which accelerates the speed of solid-liquid separation and the moisture content of the coal cake gradually decreases. When the pressure setting time is reached, the squeezing pump stops running and relieves the pressure;

[0037] Step 5: Start the belt conveyor, the filter press begins to unload automatically, and the coal cakes are unloaded from the filter press into the belt conveyor. The coal cakes with a moisture content of about 25% are finally produced and directly recovered at the rear of the vehicle through the belt conveyor. The filtered water is returned to the sedimentation tank or reused.

[0038] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various replacements, changes and modifications are possible without departing from the spirit of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
