Description

Technical Field

[0001] This invention relates to the field of copper slag dewatering technology, specifically to a copper flash blowing slag dewatering device. Background Technology

[0002] In the dewatering process of copper smelting slag, copper smelting slag with a certain moisture content is usually conveyed to a filter press for dewatering, so that the water contained in the copper slag is separated from the copper slag. The dewatered copper slag is then stored, and the dewatered water is discharged into a pit for collection. The filtration time is usually from one minute to several minutes.

[0003] In the existing copper smelting slag filter press, the process of filtering copper smelting slag usually involves manually putting the water-containing copper slag into the filter press, then dewatering the copper slag by pressing and filtering. The dewatered copper slag is then taken out of the filter press, and then the copper slag that needs to be dewatered is put into the filter press again to achieve the dewatering of a large amount of accumulated copper slag.

[0004] However, the existing method of dewatering copper slag requires manual intervention for each feeding and unloading process in the filter press, which is time-consuming, labor-intensive, and inefficient. Furthermore, the existing filter press uses a longitudinal arrangement to filter the copper slag during each filtration process, making it difficult to quickly separate the overflow water from the copper slag. As a result, the overflow water is easily reabsorbed by the copper slag after filtration, leading to poor dewatering effect.

[0005] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a copper flash blowing slag dewatering device to solve the problems mentioned in the background art, which require manual intervention for dewatering copper slag, are time-consuming and labor-intensive, have low work efficiency, and the overflow water after filtration is difficult to separate from the copper slag quickly, resulting in the overflow water after filtration being easily reabsorbed by the copper slag, leading to poor dewatering effect.

[0025] The ejector plate is fixedly connected to the upper end of the lifting block and is used to squeeze the copper slag.

[0026] Furthermore, the upper end of the ejector plate is configured as a frustum shape that matches the extrusion chamber, which is used to squeeze the copper slag at the bottom of the extrusion chamber to complete the dehydration process.

[0029] Furthermore, the material control component includes:

The outer diameter of the first cylinder is adapted to the inner diameter of the feeding chamber, and is used to prevent the copper slag in the sliding chamber from continuing to enter the dewatering area during the dewatering process.

[0031] A guide rod is fixedly connected to the middle of the upper end of the first cylinder, and the diameter of the guide rod is smaller than the inner diameter of the feed chamber;

[0032] The second cylinder is slidably sleeved on the outside of the guide rod to prevent the copper slag in the sliding chamber from entering the dewatering area when the dewatered copper slag slides down along the extrusion assembly. The lower end of the second cylinder is provided with a second inclined surface adapted to the sliding chamber. The outer diameter of the second cylinder is larger than the inner diameter of the feeding chamber.

[0033] The second limiting block is fixedly connected to the upper end of the guide rod and is used to limit the second cylinder.

[0034] A preload spring is slidably sleeved on the outside of the guide rod. The upper end of the preload spring is connected to the second limiting block and the upper end is connected to the second cylinder, which is used to press the second cylinder against it.

[0035] Furthermore, the water storage component includes:

[0036] A water guide pipe is connected at one end to the lower end of the extrusion assembly to drain water from the extrusion assembly. The water guide pipe is L-shaped, and the other end of the water guide pipe is slidably inserted into a guide rail set inside the dehydration chamber.

[0037] A sealing ring is provided at the contact point between the water pipe and the guide rail to seal the water inside the water pipe;

[0038] A flow guide hole is located inside the dehydration chamber and is connected to the outlet of the water guide pipe;

[0039] A water outlet pipe is connected to the outside of the dehydration chamber and communicates with the guide hole;

[0040] A water collection frame, placed on the upper part of the base plate, is used to collect the water discharged from the outlet pipe.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] 1. This invention activates a hydraulic cylinder, which drives the ejector plate upward via a lifting block. This causes the ejector plate to contact the baffle plate and gradually push the baffle plate upward. The baffle plate gradually compresses the clamping spring via a first limiting block. The ejector plate drives the guide rod upward via a first cylinder, which in turn drives the second cylinder upward. At this point, the second inclined surface disengages from the sliding chamber, and the first cylinder separates from the feeding chamber. The copper slag buffered on the sliding chamber slides down the inner wall of the sliding chamber under the action of gravity into the dehydration area between the ejector plate and the extrusion chamber, thus achieving the effect of automatic feeding.

[0043] 2. In this invention, when the first cylinder gradually moves upward into the feeding chamber, the feeding chamber is blocked, and the feeding operation stops. After that, the ejector plate continues to move upward, so that the copper slag in the dehydration area between the ejector plate and the extrusion chamber is squeezed out of water. The squeezed water falls into the buffer tank through the water inlet for collection. After the dehydration operation is completed, the hydraulic cylinder drives the ejector plate to quickly descend and separate from the baffle plate through the lifting block. Then, the copper slag after being dragged out of water slides down the ejector plate along its own gravity and inertia to the bottom of the dehydration chamber and is discharged through the discharge port. Then, the feeding operation of the dehydration area of ​​the next cycle is carried out, thereby achieving the effect of automatic continuous dehydration and feeding and discharging. The whole process does not require manual intervention and has high work efficiency.

[0044] 3. In this invention, the first cylinder, under the action of the guide rod, drives the second cylinder to descend rapidly until it contacts the inner wall of the material sliding chamber, so that the feeding chamber is blocked in time. This prevents the dehydrated copper slag from sliding down the top plate into the dehydration area before the second cylinder blocks the feeding chamber, thus preventing the dehydrated copper slag from becoming damp again.

[0045] 4. This invention features a top plate with a frustum-shaped upper part. When the top plate squeezes out the water from the copper slag, the squeezed water moves downward along the top plate, allowing for rapid separation between the squeezed water and the copper slag. When the squeezed water reaches the water inlet, it flows through the water inlet into the buffer tank for storage. As the lifting block moves downward, it drives the water guide pipe to move along the guide rail to the bottom of the guide rail. At this point, the outlet of the water guide pipe connects with the guide hole, and the water in the buffer tank flows sequentially through the water guide pipe, guide hole, and outlet pipe into the water collection frame for collection. This achieves the effect of quickly separating the dehydrated water from the copper slag during the dehydration process, preventing the dehydrated water from being reabsorbed by the copper slag, resulting in a good dehydration effect.

[0084] Furthermore, the water storage component 22 includes:

[0085] The water guide pipe 221 is connected at one end to the lower end of the extrusion assembly 21 and is used to drain the water in the extrusion assembly 21. The water guide pipe 221 is L-shaped and the other end of the water guide pipe 221 is slidably inserted into the guide rail 1012 provided inside the dehydration chamber 101.

[0086] A sealing ring 222 is provided at the contact point between the water pipe 221 and the guide rail 1012 to seal the water inside the water pipe 221;

[0089] The water collection frame 224 is placed on the upper end of the base plate 100 and is used to collect the water discharged from the water outlet pipe 223.

[0090] It should be noted that in the specific implementation of this invention: initially, the second cylinder 233 closes the feeding chamber 112, the ejector plate 213 separates from the bottom of the baffle plate 121, and the conveyor belt sends the copper slag to be dehydrated into the dehydration chamber 101. After entering the dehydration chamber 101, the copper slag accumulates in the sliding chamber 111 for buffering. When the dehydration area needs to be fed, the hydraulic cylinder 24 is activated. The hydraulic cylinder 24 drives the ejector plate 213 to move upward through the lifting block 211, so that the ejector plate 213 contacts the baffle plate 121 and gradually pushes the baffle plate 121 upward. The baffle plate 121 gradually compresses the top spring 122 through the first limiting block 1211. The ejector plate 213 drives the guide rod 232 to move upward through the first cylinder 231. The guide rod 232 drives the second cylinder 233 to move upward. At this time, the second inclined surface 2331 is separated from the sliding cavity 111, and the first cylinder 231 is separated from the feeding cavity 112. The copper slag buffered on the sliding cavity 111 slides down along the inner wall of the sliding cavity 111 under the action of gravity into the dewatering area between the ejector plate 213 and the extrusion cavity 113, thereby achieving the effect of automatic feeding.

[0091] When the first cylinder 231 gradually moves upward into the feeding chamber 112, the feeding chamber 112 is blocked, and the feeding operation stops. After that, the ejector plate 213 continues to move upward, so that the copper slag in the dehydration area between the ejector plate 213 and the extrusion chamber 113 is squeezed out of water. The squeezed water falls into the buffer tank 212 along the water inlet 214 for collection. After the dehydration operation is completed, the hydraulic cylinder 24 drives the ejector plate 213 to descend quickly through the lifting block 211 to separate from the baffle plate 121. Then, the copper slag after being dragged out of water slides down the ejector plate 213 along its own gravity and inertia to the bottom of the dehydration chamber 101 and is discharged along the discharge port 1011. Then, the feeding operation of the dehydration area of ​​the next cycle is carried out, thus achieving the effect of automatic continuous dehydration and feeding and discharging. The whole process does not require manual intervention and has high work efficiency.

[0092] It should be noted that as the ejector plate 213 rapidly descends to separate from the baffle plate 121, the ejector plate 213, through the first cylinder 231 and under the action of the guide rod 232, drives the second cylinder 233 to rapidly descend to contact the inner wall of the sliding chamber 111, so that the feeding chamber 112 is blocked in time, preventing the dehydrated copper slag from sliding down the ejector plate 213 into the dehydration area before the second cylinder 233 blocks the feeding chamber 112, thus preventing the dehydrated copper slag from becoming damp again.

[0093] This invention features a top plate 213 with a frustum-shaped upper part. When the top plate 213 squeezes out the water from the copper slag, the squeezed water moves downward along the top plate 213, allowing the squeezed water to quickly separate from the copper slag. When the squeezed water reaches the water inlet 214, it flows through the water inlet 214 into the buffer tank 212 for storage. When the lifting block 211 moves downward, it drives the water guide pipe 221 to move along the guide rail 1012 to the bottom of the guide rail 1012. At this time, the outlet of the water guide pipe 221 is connected to the guide hole 1013. The water in the buffer tank 212 flows sequentially through the water guide pipe 221, the guide hole 1013, and the outlet pipe 223 into the water collection frame 224 for collection. This achieves the effect of quickly separating the dehydrated water from the copper slag during the dehydration process, preventing the dehydrated water from being reabsorbed by the copper slag, resulting in a good dehydration effect.
