Description

Technical Field

[0001] The utility model relates to the technical field of phosphogypsum waste residue washing, in particular to a phosphogypsum waste residue washing device. Background Art

[0002] Wet-process phosphoric acid phosphogypsum waste residue is a by-product generated in the production process of wet-process phosphoric acid. Its main components are calcium phosphate and hydrated calcium sulfate. Wet-process phosphoric acid phosphogypsum waste residue usually exists in solid form and has a certain viscosity. The purpose of flushing wet-process phosphoric acid phosphogypsum waste residue is to remove impurities and residual substances therein to reduce pollution and harm to the environment. By flushing wet-process phosphoric acid phosphogypsum waste residue, harmful substances therein can be effectively removed and its harm to the environment can be reduced. In addition, flushing can also improve the physical properties of wet-process phosphoric acid phosphogypsum waste residue, such as improving its dryness, reducing viscosity, etc., to facilitate subsequent treatment and utilization.

[0003] Most of the existing phosphogypsum waste slag flushing devices use horizontal belt conveyors to transport the phosphogypsum waste slag during the flushing operation, and flush it through a water curtain type flushing structure horizontally set on the conveyor. However, since the bottom surface of the phosphogypsum waste slag is in contact with the conveyor belt during the transportation process, when the water curtain flushes the phosphogypsum waste slag passing below, the bottom surface of the phosphogypsum waste slag is often not effectively cleaned, resulting in blind spots for cleaning.

[0004] In view of this, Chinese patent CN220942086U discloses a wet-process phosphate gypsum waste residue flushing device, which improves the traditional horizontal belt conveyor, forms a feeding group with a stepped conveying surface on the inner side of the frame with two diagonally arranged rollers and four supporting rollers, and cooperates with the baffle group to form a flushing cavity for accommodating the phosphogypsum waste residue under the flushing mechanism, and then with the help of the forward and reverse rotation of the servo motor, the phosphogypsum waste residue in the flushing cavity can be fully flushed, eliminating the flushing dead corners and improving the cleaning effect.

[0005] However, by comparing the above existing documents, the inventors believe that there are the following defects:

[0006] The above-mentioned document can fully flush the phosphogypsum waste slag in the flushing chamber through the forward and reverse rotation of the servo motor, eliminating the flushing dead corners. However, in actual use, during the reversal process of the conveyor belt, it greatly affects the subsequent cleaning time of the phosphogypsum waste slag, thereby reducing the efficiency of the phosphogypsum waste slag cleaning. Therefore, we propose a phosphogypsum waste slag flushing device to solve the above problem. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1A phosphogypsum waste slag washing device includes a conveyor 1 and baffles 2 installed on both sides thereof, two water pipes 3 are provided on the surface of the baffle 2, a plurality of duckbill nozzles 4 are fixedly installed at the bottom of the water pipes 3, and a U-shaped plate 19 is fixedly installed between the two water pipes 3.

[0026] Among them, a water supply component is provided on the upper surface of the water pipe 3, and a stirring component is provided between the two water pipes 3.

[0027] The water supply component is used to provide cleaning liquid to flush the phosphogypsum waste residue, while the stirring component is used to stir the phosphogypsum waste residue to reduce cleaning dead corners and improve cleaning quality.

[0028] In addition, the U-shaped plate 19 is not only used to install the device, but also to prevent the phosphogypsum waste residue from being easily spilled out of the conveyor 1 when it collides and reverses with the cleaning liquid.

[0029] See also Figure 2 , Figure 3 and Figure 4 The stirring assembly includes a rotating rod 10 rotatably mounted on the inner wall of a U-shaped plate 19, a plurality of flip plates 11 are mounted on the surface of the rotating rod 10, a fixed platform 5 with an inclined surface is fixedly mounted on the inner wall of the U-shaped plate 19, an arc-shaped baffle 6 is fixedly mounted on the top of the upper surface of the fixed platform 5, a discharge port 7 is also opened on the surface of the fixed platform 5, a rotating shaft 8 is rotatably mounted on the inner wall of the discharge port 7, and a plurality of blocking plates 9 are fixedly mounted on the surface of the rotating shaft 8,

[0030] Among them, through the water pipe 3 and several duckbill nozzles 4, the cleaning liquid can form a water curtain to flush the phosphogypsum waste residue on the surface of the conveyor 1, and the setting of two groups of water pipes 3 and duckbill nozzles 4 allows the phosphogypsum waste residue to be flushed multiple times, ensuring the flushing effect.

[0031] At the same time, when the phosphogypsum waste moves with the water flow to between the two water pipes 3, the flipping of the flip plate 11 can speed up the movement of the waste with the water flow, so that it can rush to the fixed platform 5. The setting of the arc-shaped baffle plate 6 can block and flip the waste and water flow, thereby realizing the collision and flipping of the waste, thereby improving the cleaning effect of the waste and reducing the cleaning dead corners. The flipped waste will flow out through the discharge port 7 for re-rinsing, thereby improving the cleaning quality of the phosphogypsum waste, and at the same time it is not easy to affect the subsequent inflow of phosphogypsum for cleaning, thereby improving the cleaning efficiency of the phosphogypsum waste.

[0032] It is worth noting that the rotating shaft 8 will drive the sealing plate 9 to rotate when it rotates. When the sealing plate 9 is not parallel to the inclined surface of the fixed platform 5, the discharge port 7 is in an open state, which is convenient for waste residue and water to pass through. When the sealing plate 9 is parallel to the inclined surface of the fixed platform 5, the discharge port 7 is blocked by the sealing plate 9. The sealing plate 9 is used to reduce the amount of waste residue that flows directly out of the discharge port 7 before the collision and flipping when the waste residue moves to the surface of the fixed platform 5 with the cleaning liquid and collides and flips. Here, the sealing plate 9 can be set to multiple, so as to increase the blocking frequency of the discharge port 7.

[0033] In addition, the two side walls of the U-shaped plate 19 are in contact with the inner walls of the two baffles 2 , and the lower surface of the fixing platform 5 is in contact with the upper surface of the conveyor 1 .

[0034] In this embodiment, the water supply assembly includes a water inlet pipe 13, on the surface of which two branch pipes 12 are fixedly installed. The two branch pipes 12 are respectively connected to the corresponding water pipes 3, and the water inlet pipe 13 is connected to an external water source.

[0035] It is worth noting that the present application preferably has two groups of water pipes 3 and duckbill nozzles 4, that is, two flushings are performed, and according to the length of the conveyor belt, the device can be set to multiple groups, thereby improving the flushing quality by increasing the number of flushings of the phosphogypsum waste residue, and the stirring components also need to be increased.

[0036] In addition, the discharge port 7 is arranged to be inclined downward, and the rotating shaft 8 and the blocking plate 9 are located on a side of the inner wall of the discharge port 7 close to the inclined surface of the fixing platform 5 .

[0037] See also Figure 5 In this embodiment, one end of the rotating rod 10 and the rotating shaft 8 extend to the outside of one side baffle 2, and a pulley 16 is fixedly installed on one end of the rotating rod 10 and the rotating shaft 8 located outside the baffle 2.

[0038] A driving assembly for driving the rotating rod 10 and the rotating shaft 8 to rotate simultaneously is also provided on the outer side of the baffle 2, and the driving assembly includes a driving belt 17 that is transmission-connected to both pulleys 16. A motor 18 is fixedly mounted on one side of the baffle 2, and the output end of the motor 18 is fixed to one side of the pulley 16.

[0039] The starter motor 18 drives the pulley 16 to rotate, and then drives the belt 17 to rotate another pulley 16, thereby causing the rotating rod 10 and the rotating shaft 8 to rotate simultaneously, thereby reducing the production cost of the device.

[0040] See also Figure 4In this embodiment, a first sealing sleeve 15 extending to the outside of the baffle 2 is fixedly installed on the inner wall of one side of the U-shaped plate 19, and the rotating shaft 8 is rotatably connected to the inner wall of the first sealing sleeve 15. A second sealing sleeve 14 extending to the outside of the baffle 2 is also fixedly installed on the inner wall of one side of the U-shaped plate 19, and the rotating rod 10 is rotatably connected to the inner wall of the second sealing sleeve 14.

[0041] The first sealing sleeve 15 and the second sealing sleeve 14 are provided to improve the sealing performance of the rotating rod 10 and the rotating shaft 8 when they are in contact with the baffle plate 2 and the side wall of the U-shaped plate 19 .

[0042] When the present embodiment is in use, the phosphogypsum waste residue is placed on the conveyor 1, and the external cleaning liquid enters the water pipe 3 to the inside through the water inlet pipe 13 and the diversion pipe 12, and the duckbill nozzle 4 forms a water curtain to wash the phosphogypsum waste residue passing through, and the motor 18 is started to drive the pulley 16 to rotate, and then the other pulley 16 is rotated by the driving belt 17, so that the rotating rod 10 and the rotating shaft 8 rotate at the same time, and the rotating rod 10 will drive the flip plate 11 to rotate when rotating, and when the phosphogypsum and the cleaning liquid move between the two water pipes 3, the flip plate 11 is turned. The movement can accelerate the movement speed of the waste slag along with the water flow, so that it can rush to the fixed platform 5. The setting of the arc baffle 6 can block and flip the waste slag and water flow, thereby realizing the collision and flipping of the waste slag. The rotating shaft 8 will drive the sealing plate 9 to rotate when it rotates. When the sealing plate 9 is not parallel to the inclined surface of the fixed platform 5, the discharge port 7 is in an open state, which is convenient for the waste slag and water flow to pass through. The waste slag after passing through will be rinsed again through another duckbill nozzle 4, thereby improving the cleaning quality of the phosphogypsum waste slag and not easily affecting the subsequent inflow and cleaning of the phosphogypsum.

[0043] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

For those skilled in the art, the present invention may have various modifications and variations.
