Description

Technical Field

[0001] This invention relates to the field of cleaning system technology, and more particularly to an automatic water tank cleaning system. Background Technology

[0002] The matte produced by the flash smelting furnace needs to undergo air quenching before proceeding to the next process. During air quenching, a clear water tank supplies water to the granulation system. The water quality in the clear water tank is affected by the drainage from the sump and the overflow water from the air quenching flue gas purification system. Over time, a large amount of sediment accumulates at the bottom of the tank. This sediment, when sucked into the atomizing pump, can cause blockages, affecting the granulation water flow and resulting in poor granulation. In severe cases, it can damage the granulation system, threatening production safety. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings mentioned above by providing an automatic water tank cleaning system that automatically cleans the clear water tank and ensures the water quality of the tank.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: an automatic water tank cleaning system, including a clear water tank, a transmission system mounted on the clear water tank, and a suction device for suctioning sediment in the clear water tank at the transmission end of the transmission system. The transmission system is used to drive the suction device to move linearly along the X-axis and Y-axis of the clear water tank.

[0005] The suction device includes an electric push rod and a water pump driven by the transmission system, and a suction pipe connected to the piston rod of the electric push rod. The top end of the suction pipe is connected to the input end of the water pump through a telescopic pipe. The suction pipe includes two vertically distributed rigid pipes A and B, and a flexible hose disposed between the rigid pipes A and B. A universal coupling is provided between the rigid pipes A and B, so that the rigid pipe B can rotate around the universal coupling in the X and Y directions of the clear water tank.

[0006] The suction device further includes a dial plate disposed at the bottom end of the rigid tube B, a turbine blade rotatably connected to the bottom of the dial plate, a limiting plate disposed on the rigid tube B, and a spring rod disposed on the dial plate and passing through the limiting plate. The dial plate and the turbine blade are both sleeved on the rigid tube B, and the dial plate is provided with a motor that drives the turbine blade to rotate.

[0007] The rotation of the turbine blades causes the water and sediment in the clear water tank to gather towards the bottom of the hard pipe B. The actuation disk extends upward in an arc shape around its perimeter. When the transmission system drives the actuation disk to move, the sediment on the side squeezes the arc of the actuation disk, causing one end of the actuation disk to tilt upward.

[0008] Furthermore, the transmission system includes a first slide rail disposed on both sides of the top of the clear water tank, a first trolley slidably mounted on each of the first slide rails, a second slide rail connected to the first trolley, and a second trolley slidably disposed on the second slide rail. The first trolley and the second trolley move linearly along the X-axis and Y-axis of the clear water tank within the first slide rail and the second slide rail, respectively. The water pump is mounted on the second trolley, and the electric push rod is disposed at the bottom of the second trolley.

[0009] Furthermore, the universal coupling includes a half coupling A connected to the bottom end of the rigid pipe A, a half coupling B connected to the top end of the rigid pipe B, and a central ring disposed within the half coupling A and the half coupling B. The half coupling A and the half coupling B are hinged in a cross shape to the outer wall of the central ring. The central ring is sleeved on the outside of the flexible hose, so that when the universal coupling turns, it drives the flexible hose to bend synchronously without affecting the connectivity of the suction pipe for sludge extraction.

[0010] Furthermore, multiple rolling balls are provided around the upward-extending perimeter of the actuating disc;

[0011] When the transmission system drives the suction pipe to the corner of the clear water tank, multiple balls on the actuating disc move accordingly and, upon contacting the inner wall of the clear water tank, raise one side of the actuating disc, forming a triangle with the bottom and side walls of the clear water tank. Subsequently, the electric push rod drives the rigid pipe A to descend and squeeze the inclined rigid pipe B. The rigid pipe B, which is squeezed and descends, extends from the actuating disc to suck up the sediment at the corner of the clear water tank.

[0012] Furthermore, a first conveying device is provided on the outer side of the second slide rail, and a second conveying device is provided on the outer side of the first slide rail. The output end of the water pump is located above the first conveying device, the output end of the first conveying device is located above the second conveying device, and the output end of the second conveying device is provided with a discharge pipe.

[0013] Furthermore, a filter layer is provided at the bottom wall of the first conveying device, a water tank A is provided at the bottom of the filter layer, a water tank B is provided on the outer wall of the clear water pool, the outlet of the water tank A is located above the water tank B, and the outlet of the water tank B is connected to the interior of the clear water pool.

[0014] Furthermore, both half-coupling A and half-coupling B are provided with a coil spring for resetting at the pivot joint where they are hinged to the central ring, so that the rigid tube B is reset to remain vertical with the rigid tube A in the unrestricted state.

[0015] Furthermore, it also includes a filtration device located outside the clear water tank. The filtration device includes an outer casing and an inner casing installed inside the outer casing. The top of the inner casing is open. The filtration device is equipped with a stirring device for stirring the interior of the inner casing. An external discharge pipe is located below the filtration device. The external discharge pipe includes an external discharge pipe A and an external discharge pipe B, which are respectively connected to the inner casing and the outer casing. The discharge pipe is connected to the inner casing. A discharge valve is installed on the external discharge pipe.

[0016] The beneficial effects of this invention are reflected in:

[0017] This invention utilizes a transmission system installed on a clear water tank to enable a suction device to travel along the X and Y axes of the tank. During this travel, the suction device, in conjunction with controlled turbine blade rotation, draws sediment from the clear water tank closer to the rigid pipe B and sucks it in. This improves the range and efficiency of sediment suction. Furthermore, the agitator extends upwards in an arc shape around its perimeter. As the suction device operates, the amount of sediment at the bottom of the rigid pipe B decreases with suction. Therefore, when the transmission system drives the agitator forward, the lower sediment level at the bottom and higher sediment level on the sides of the agitator cause the arc-shaped agitator to be compressed by the sediment on the sides, causing the agitator to tilt. This aligns the suction center of the rigid pipe B with the driving direction of the transmission system, further improving sediment suction efficiency. The sediment and water are then drawn into a filtration device for treatment, effectively removing sediment from the bottom of the clear water tank. This prevents the subsequent atomizing pump from sucking in sediment, which could negatively impact granulation efficiency or damage the granulation system, thus ensuring production safety.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-9 This invention discloses an automatic water tank cleaning system, including a clear water tank 1. A filter device is provided on the outside of the clear water tank 1, and a transmission system is provided on the clear water tank 1. A suction device is provided at the transmission end of the transmission system. The suction device is connected to the filter device, so that water and sediment can enter the tank for filtration. The transmission system is used to drive the suction device to move linearly along the X-axis and Y-axis of the clear water tank 1.

[0031] In one embodiment, the suction device includes an electric push rod 12 and a water pump 14 driven by a transmission system, and a suction pipe 13 connected to the piston rod of the electric push rod 12. The top end of the suction pipe 13 is connected to the input end of the water pump 14 through a flexible pipe. The suction pipe 13 includes two vertically distributed rigid pipes A 131 and B 132, and a flexible hose 133 connecting the rigid pipes A 131 and B 132. A universal coupling 15 is hinged between the rigid pipes A 131 and B 132, allowing the rigid pipe B 132 to rotate about the universal coupling 15 along the X and Y axes of the clear water tank 1. The suction device also includes a rotary disc 16 movably mounted on the bottom end of the rigid pipe B 132, a turbine blade 17 rotatably connected to the bottom of the rotary disc 16 via bearings, and a fixed connection to the rigid pipe B 132. The limiting plate 18 on the outer wall of the middle part of 132 and the spring rod 19 vertically installed on the dial 16 and passing through the limiting plate 18. At the same time, the dial 16 and the turbine blade 17 are both sleeved on the rigid tube B132, and the motor 20 that drives the turbine blade 17 to rotate is installed on the dial 16.

[0032] In one embodiment, the turbine blade 17 consists of a blade body 171 and a gear ring 172 fixedly mounted on the blade body 171. The shaft of the motor 20 faces downward and is equipped with a gear 21, which meshes with the gear ring 172. The motor 20 drives the gear 21 to rotate, causing the gear ring 172 to rotate around the rigid pipe B 132. The blade body 171 rotates synchronously. The rotation of the turbine blade 17 causes the water and sediment in the clear water tank 1 to gather and be sucked into the bottom of the rigid pipe B 132, thus improving the absorption range and efficiency of sediment. At this time, the sediment at the bottom of the rigid pipe B 132 is reduced, while the actuating disk 16 extends upward in an arc shape around its perimeter. Therefore, when the transmission system drives the actuating disk 16 to move, there is less sediment at the bottom of the actuating disk 16 and more sediment on its sides. The arc of the moving actuating disk 16 is squeezed by the sediment on its sides, causing the actuating disk 16 to tilt accordingly, causing the rigid pipe B 132 to be sucked into the hard pipe B 132. The suction center of 132 is aligned with the driving direction of the transmission system, which effectively improves the suction efficiency.

[0033] Water and sediment are drawn into the filtration device through the suction device. The filtration device separates the water and sediment. The separated water can be repeatedly discharged into the clear water tank 1, while the sediment is transferred later. This ensures that the sediment at the bottom of the clear water tank 1 is treated, so that the subsequent atomizing pump will not suck in sediment, which would affect the granulation effect and damage the granulation system, thus ensuring production safety.

[0034] Understandably, the transmission system can drive the suction device to move linearly along the X and Y axes of the clear water tank 1, while the rigid pipe B 132 can rotate around the universal coupling 15 along the X and Y axes of the clear water tank 1, so that the rotation direction of the actuating disk 16 can always be synchronized with the driving direction of the transmission system, so as to ensure the accuracy and efficiency of suction.

[0035] In one embodiment, the transmission system includes a first slide rail 2 installed on the top of the clear water tank 1, a first trolley 3 slidably installed in the first slide rail 2, a second slide rail 4 connected to the first trolley 3, and a second trolley 5 slidably installed in the second slide rail 4. Both the first trolley 3 and the second trolley 5 are equipped with motors for power and control devices for signal processing and control. A water pump 14 is installed on the second trolley 5, and an electric push rod 12 is installed at the bottom of the second trolley 5.

[0036] In specific implementation, there are two first slide rails 2, which are installed parallel to each other on the top of the two side walls of the clear water tank 1. The second slide rail 4 is set between the two first slide rails 2 and forms an I-shape. The control device is used to send and receive control signals and connect the motor equipment. When a move or stop signal is issued, the signal is transmitted to the control device. The control device gives instructions to make the motor equipment on the first trolley 3 and the second trolley 5 move or stop. The motor equipment can drive the first trolley 3 and the second trolley 5 to move linearly along the X-axis and Y-axis of the clear water tank 1 in the first slide rail 2 and the second slide rail 4 respectively, and can stop at the corresponding point, so that the suction device works at the corresponding position in the clear water tank 1.

[0037] In one embodiment, the universal coupling 15 includes a half coupling A151 connected to the bottom end of the rigid tube A131, a half coupling B152 connected to the top end of the rigid tube B132, and a central ring 153 disposed within the half couplings A151 and B152. The half couplings A151 and B152 are hinged in a cross shape to the outer wall of the central ring 153, and the central ring 153 is sleeved on the outside of the flexible tube 133.

[0038] In practice, rigid pipe A 131 is connected to the piston rod of electric push rod 12, and its angle cannot be changed. Rigid pipe B 132 is connected to rigid pipe A 131 through universal coupling 15, so that rigid pipe B 132 can rotate around universal coupling 15. When kept straight, rigid pipe A 131, rigid pipe B 132 and hose 133 are connected. When rigid pipe B 132 turns and bends, it drives hose 133 to bend synchronously. The setting of central ring 153 can make the entire universal coupling 15 coincide with sludge suction pipe 13. This can ensure that rigid pipe B 132 can rotate in multiple directions around rigid pipe A 131 without affecting the connectivity of sediment suction inside the entire sludge suction pipe 13.

[0039] In one embodiment, a first conveying device 6 is installed on the outer side of the second slide rail 4, and a second conveying device 7 is installed on the outer side of the first slide rail 2. The output end of the water pump 14 is located above the first conveying device 6, the output end of the first conveying device 6 is located above the second conveying device 7, and a discharge pipe 8 is installed at the output end of the second conveying device 7.

[0040] In one embodiment, both the first conveying device 6 and the second conveying device 7 can be screw conveyors. The water pump 14 draws water and sediment from the clear water tank 1 and guides them to the first conveying device 6. The first conveying device 6 then conveys them linearly to the second conveying device 7. Since the second slide rail 4 is connected to and parallel to the first conveying device 6, and the first slide rail 2 is connected to and parallel to the second conveying device 7, when the water pump 14 moves with the second trolley 5, the output end of the water pump 14 is always on the first conveying device 6. When the first conveying device 6 and the second slide rail 4 move with the first trolley 3, the output end of the first conveying device 6 is always on the second conveying device 7. Therefore, water and sediment can always be conveyed and processed in both static and dynamic states. The water and sediment are discharged from the output end of the second conveying device 7 to the discharge pipe 8.

[0041] In one embodiment, a plurality of rolling balls 22 are rolledly installed around the upward extension of the dial 16, and the rolling balls 22 are omnidirectionally rotatable.

[0042] In practice, multiple rolling balls 22 are movably installed around the upward-extending perimeter of the actuating disk 16, distributed along the arc shape of that area. Each rolling ball 22 can roll in all directions. During use, the sludge suction pipe 13 is driven by the transmission system to the corner of the clear water tank 1. As the actuating disk 16 moves, the multiple rolling balls 22 gradually approach and adhere to the bottom and inner side walls of the clear water tank 1. At this time, the electric push rod 12 drives the rigid pipe A 131 to descend and squeeze the inclined rigid pipe B 132. During the descent and squeezing process, the rigid pipe B 132 and the actuating disk 16 increase the angle of inclination. The rolling balls 22 slide and adhere to the inner wall of the clear water tank 1, making the angle expansion very smooth. After the angle is appropriate, the movement stops and the squeezing of the rigid pipe B 132 continues. The rigid pipe B 132 descends under the squeezing. 132 extends from the fixed-angled actuation plate 16 and approaches the corner of the clear water tank 1, thereby getting closer to the sediment present at the corner of the clear water tank 1, thus improving the efficiency of sediment removal. During reset, since the limiting plate 18 is provided to install the spring rod 19 on the actuation plate 16, the spring rod 19 plays a reset role, causing the actuation plate 16 to be pressed down and reset in the unlimited state.

[0043] In one embodiment, both the first conveying device 6 and the second conveying device 7 are set in an inclined state, and the height of their entry points is lower than the height of their exit points. The bottom wall of the first conveying device 6 is hollowed out, and a water filter layer 23 is installed there. A water tank A 24 is installed at the bottom of the water filter layer 23, and a water tank B 25 is installed on the outer wall of the clear water pool 1. The outlet of the water tank A 24 is located above the water tank B 25, and the outlet of the water tank B 25 is connected to the interior of the clear water pool 1.

[0044] In practice, during the linear transport of sediment and water by the first conveying device 6, since the first conveying device 6 and the second conveying device 7 are inclined, more water stays at the inlet and outlet and is not discharged from the outlet along with too much sediment. The water passes through the filter water layer 23 and flows downward into the water tank A 24. The water tank A 24 then conducts the water to the water tank B 25 and finally returns the water to the clear water tank 1. This allows the water and sediment to be filtered before being absorbed and centrifuged, thus reducing the loss of water in the clear water tank 1.

[0045] In one embodiment, coil springs for resetting are movably installed at the pivots where half-coupling A 151 and half-coupling B 152 are hinged to the central ring 153.

[0046] In practice, when the rigid tube B 132 is pressed down and tilted, the coil spring will not be triggered because it is in a limited state. When the rigid tube is released from the limited state, the coil spring drives the rigid tube B 132 to reset, so that the rigid tube B 132 is reset to be aligned with the rigid tube A 131 in the unlimited state.

[0047] In one embodiment, a level gauge and a water supply pipe are installed on the inner wall of the clear water tank 1. A solenoid valve is installed at the water supply pipe. The level gauge is used to detect the level of the clear water tank 1. When the level gauge detects that the water level has reached a low threshold, it sends a relevant signal to the valve device. The valve device is equipped with a corresponding signal transceiver. The signal transceiver is used to send a switching signal to the solenoid valve so that the water supply pipe can replenish the clear water tank 1 in a timely manner, preventing the water pump 14 from running dry due to the low water level.

[0048] In one embodiment, a filter device 9 is also included, which is installed on the outside of the clear water tank 1. The filter device 9 includes an outer casing 91 and a cylindrical inner casing 92 installed inside the outer casing 91. The top of the inner casing 92 is open. The filter device 9 is provided with a stirring device 10 to stir the water inside the inner casing 92 and make it vortex-like. An external discharge pipe 11 is provided below the filter device 9. The external discharge pipe 11 includes an external discharge pipe A 111 and an external discharge pipe B 112 that are respectively connected to the inner casing 92 and the outer casing 91. The discharge pipe 8 is connected to the inner casing 92. The external discharge pipe A 111 is connected to the center of the bottom of the inner casing 92. A discharge valve for controlling the opening and closing of the external discharge pipe A 111 is also connected to the external discharge pipe A 111.

[0049] In practice, the discharge valve is closed, and the first conveying device 6 and the second conveying device 7 transport the sediment to the discharge pipe 8. The discharge pipe 8 guides the sediment mixed with water into the inner tank 92. At this time, the stirring device 10 is started to stir the sediment in the inner tank 92, making the water in the inner tank 92 vortex. Since the sediment is heavier, it is located at the bottom of the vortex, so the clean water will overflow the top of the inner tank 92 and enter the outer tank 91, thereby quickly filtering and separating the water and sediment. After the vortex has been generated for a period of time, the stirring device 10 is turned off and the mixture is allowed to gather in the middle of the inner tank 92. At this time, the discharge valve at the outer discharge pipe A 111 is opened to discharge the sediment. In practice, the discharge time of the sediment can be controlled to avoid excessive loss of clean water.

[0050] It is understandable that both the outflow pipe A 111 and the outflow pipe B 112 mentioned above are connected to transfer pumps. The sediment at the outflow pipe A 111 is efficiently discharged by the transfer pump, while the clean water at the outflow pipe B 112 is repeatedly transferred to the clean water tank 1 by the transfer pump, thereby improving the efficiency of clean water collection.
