Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, in particular to an overflow grading type diamond micro powder washing machine. Background Art

[0002] The stirred tank ore washer is a commonly used mineral cleaning equipment, especially suitable for cleaning fine-grained materials such as diamond powder;

[0003] A suitable amount of water and detergent are added to the mixing tank to form a mixed liquid, and then diamond powder is added. The diamond powder is separated from impurities by mechanical stirring. The lighter impurities will be suspended in the mixed liquid and discharged by overflow, while the heavier diamond powder will settle at the bottom. The diamond powder can then be discharged from the bottom.

[0004] When discharging diamond powder from the agitated tank washing machine in the above-mentioned manner, if it is discharged directly, a large amount of mixed liquid will flow out together with the diamond powder, which not only increases the workload of subsequent filtration and separation, but also makes it impossible to effectively recycle the mixed liquid. Summary of the Invention

[0005] In order to overcome the shortcomings of directly discharging diamond micropowder, which will cause the mixed liquid to mix with the micropowder, increase the separation burden, waste the mixed liquid, and increase the cost, the present invention provides an overflow grading diamond micropowder washing machine.

[0006] The technical solution is: an overflow grading diamond powder washing machine, including a washing tank, a motor, a stirring plate, a feed pipe and a liquid inlet pipe; the washing tank is fixedly connected to the motor; the washing tank is rotatably connected to the stirring plate; the motor output shaft is fixedly connected to the stirring plate; the washing tank is connected to the feed pipe, and the washing tank is connected to the liquid inlet pipe; the washing tank is provided with a drainage trough for discharging suspended impurities; the motor is connected to an external power supply; it also includes an electric push rod, a lifting cylinder and a discharge pipe; at least two electric push rods are fixedly connected to the bottom of the washing tank; the telescopic parts of all electric push rods are commonly fixedly connected to the lifting cylinder; the lifting cylinder is provided with several feed troughs; the lifting cylinder is connected to the discharge pipe; the lifting cylinder and the discharge pipe jointly form a storage space; the discharge pipe is fixedly connected to an electric control valve; the electric push rod and the electric control valve are respectively connected to the external power supply.

[0007] More preferably, the lower side of the feed chute is inclined.

[0008] More preferably, the feed pipe and the liquid inlet pipe are respectively located below the liquid drainage trough.

[0009] More preferably, a sealing strip is provided between the outer side of the lifting cylinder and the washing tank.

[0010] More preferably, the volume of the storage space is smaller than the volume of the height difference between the drain trough and the feed pipe in the washing tank.

[0011] More preferably, the washing tank further comprises a hollow block; the hollow block is fixedly connected to the bottom of the washing tank; and the hollow block is slidably connected to the discharge pipe.

[0012] More preferably, it further includes a spring; at least four springs are fixedly connected between the hollow block and the lower side of the discharge pipe; and the lifting cylinder is slidably connected to the discharge pipe.

[0013] More preferably, a guide plate is further included; the guide plate is fixedly connected to the drainage trough of the washing tank.

[0014] More preferably, an observation window is further included; the front of the washing tank is fixedly connected with the observation window, and the observation window is a glass window.

[0015] More preferably, a push plate is further included; the push plate is fixedly connected to the lower side of the stirring plate, and the lower end of the push plate corresponds to the position of the feed trough.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] By lowering the lifting cylinder, the storage space of the lifting cylinder is no longer connected to the washing tank. When the diamond micropowder is discharged, only the diamond micropowder and a small amount of mixed liquid in the storage space will be discharged, while the mixed liquid in the washing tank will not be affected, avoiding a large amount of mixed liquid and diamond micropowder flowing out together. This not only increases the workload of subsequent filtration and separation, but also makes it impossible to effectively recycle the mixed liquid.

[0018] Since the volume of the storage space is smaller than the height difference between the drain trough and the feed pipe in the washing tank, it is avoided that after the diamond micropowder in the washing tank enters the storage space, the liquid level in the washing tank drops to the feed pipe, causing the discharged mixed liquid and diamond micropowder to come into contact with suspended impurities; after the diamond micropowder in the storage space is discharged, the diamond micropowder can continue to be discharged for washing.

[0019] When the lifting cylinder descends, the storage space will gradually decrease. When the lifting cylinder descends, it will squeeze the mixed liquid to discharge the mixed liquid from the storage space, and it can squeeze the diamond micropowder to make the diamond micropowder completely fill the storage space, which makes it easier to separate the diamond micropowder from the mixed liquid after it is discharged.

[0020] After the upper side of the inner wall of the lifting cylinder contacts the diamond micropowder, the lifting cylinder continues to descend and the diamond micropowder will squeeze the discharge pipe, causing the discharge pipe to descend and squeeze the spring. The spring will be in a compressed state. At this time, the size of the storage space remains unchanged, but the storage space as a whole will be in a descending state, so that the lifting cylinder can normally descend back to its original position, avoiding the diamond micropowder from getting stuck in the lifting cylinder, causing the storage space to be connected to the washing tank, causing a large amount of mixed liquid to be discharged, affecting the subsequent separation of diamond micropowder.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: An overflow classification type diamond powder washing machine, such as Figure 1-Figure 4 As shown, it includes a washing tank 1, a motor 2, a stirring plate 3, a feeding pipe 4 and a liquid inlet pipe 5; the washing tank 1 is fixedly connected to the motor 2; the washing tank 1 is rotatably connected to the stirring plate 3, which is used to fully mix the discharged diamond micropowder with the mixed liquid; the output shaft of the motor 2 is fixedly connected to the stirring plate 3; the washing tank 1 is connected to the feeding pipe 4 for inputting diamond micropowder, and the washing tank 1 is connected to the liquid inlet pipe 5 for inputting the mixed liquid; the washing tank 1 is provided with a drain trough 1001 for discharging suspended impurities; the motor 2 is connected to an external power supply;

[0028] It also includes an electric push rod 6, a lifting cylinder 7 and a discharge pipe 8; two electric push rods 6 are fixedly connected to the bottom of the washing tank 1; the telescopic parts of all electric push rods 6 are commonly fixedly connected to the lifting cylinder 7; the lifting cylinder 7 is provided with four feed troughs 7001; the lifting cylinder 7 is connected to the discharge pipe 8 for discharging diamond powder; the lifting cylinder 7 and the discharge pipe 8 together form a storage space 7002; the discharge pipe 8 is fixedly connected to the electric control valve 9; the electric push rod 6 and the electric control valve 9 are respectively connected to an external power supply.

[0029] The lower side of the feed trough 7001 is inclined to facilitate the discharge of diamond powder into the storage space 7002 and to avoid the diamond powder from being left behind when the diamond powder is discharged from the storage space 7002 if the lower side of the feed trough 7001 is flat.

[0030] The feed pipe 4 and the liquid inlet pipe 5 are respectively located below the liquid drain trough 1001 to prevent the newly discharged mixed liquid and diamond powder from contacting with suspended impurities, causing the suspended impurities to adhere to the diamond powder and be washed down by the newly discharged mixed liquid.

[0031] A sealing strip is provided between the outer side of the lifting cylinder 7 and the washing tank 1 .

[0032] The volume of the storage space 7002 is smaller than the volume of the height difference between the drainage trough 1001 and the feed pipe 4 in the washing tank 1, so as to prevent the diamond powder in the washing tank 1 from entering the storage space 7002 and the liquid level in the washing tank 1 from dropping to the feed pipe 4, causing the discharged mixed liquid and diamond powder to come into contact with suspended impurities.

[0033] The washing tank 1 further includes a hollow block 111 ; the hollow block 111 is fixedly connected to the bottom of the washing tank 1 ; the hollow block 111 is slidably connected to the discharge pipe 8 .

[0034] It also includes a spring 112; four springs 112 are fixedly connected between the hollow block 111 and the lower side of the discharge pipe 8; the lifting cylinder 7 is slidably connected to the discharge pipe 8.

[0035] It also includes a guide plate 101; the guide plate 101 is fixedly connected to the drainage groove 1001 of the washing tank 1, and the discharged mixed liquid is guided by the guide plate 101 to be discharged into the external collection device.

[0036] It also includes an observation window 102; the observation window 102 is fixedly connected to the front side of the lower part of the washing tank 1. The observation window 102 is a glass window, through which the deposition and discharge of diamond powder in the washing tank 1 can be observed.

[0037] The specific working steps are:

[0038] The external feeding device is connected to the feeding pipe 4, and the external feeding device transports diamond powder. The external liquid feeding device is connected to the liquid inlet pipe 5, and the external liquid feeding device transports the mixed liquid. The guide plate 101 is connected to the external collecting device, and a collection box is placed under the discharge pipe 8.

[0039] When the diamond powder needs to be washed, the mixed liquid is first delivered to the liquid inlet pipe 5 through the external liquid delivery device, so that the mixed liquid is discharged into the washing tank 1 through the liquid inlet pipe 5. At the same time, the external feeding device delivers the diamond powder into the washing tank 1 through the feeding pipe 4, and the motor 2 will also drive the stirring plate 3 to rotate to mix the diamond powder with the mixed liquid. At this time, the diamond powder will be separated from the attached impurities, and the impurities will be suspended upward on the surface of the mixed liquid. The external liquid delivery device and the external feeding device will continue to deliver the mixed liquid and diamond powder. When the liquid level of the mixed liquid rises to the drainage trough 1001, the mixed liquid will be discharged from the drainage trough 1001 together with the impurities suspended on the surface of the mixed liquid, and then through The guide plate 101 introduces the discharged mixed liquid and impurities into the external collection device. After a period of time, the stirring plate 3 is controlled to stop stirring. At this time, the diamond micropowder will gradually sink, and the sunken diamond micropowder will accumulate at the bottom of the washing tank 1. After observing that the diamond micropowder has accumulated to a certain amount through the observation window 102, the electric push rod 6 is controlled to push the lifting cylinder 7 to rise, so that the washing tank 1 is connected to the storage space 7002 through the feeding trough 7001. At this time, part of the mixed liquid and diamond micropowder will enter the storage space 7002 through the feeding trough 7001, so that the diamond micropowder continues to enter the storage space 7002. As the amount of diamond micropowder entering the storage space 7002 increases, the diamond micropowder The powder will squeeze out the mixed liquid in the storage space 7002. When the storage space 7002 is full of diamond powder, only a small amount of mixed liquid is left in the storage space 7002. At this time, the lifting cylinder 7 is controlled to descend back to its original position, and then the electric control valve 9 is opened to discharge the diamond powder and a small amount of mixed liquid in the storage space 7002 from the discharge pipe 8 to the external collection box. By allowing the diamond powder to continuously enter the storage space 7002, a large amount of mixed liquid is avoided from being in the storage space 7002. Then, the lifting cylinder 7 is lowered so that the storage space 7002 of the lifting cylinder 7 is no longer connected to the washing tank 1. When the diamond powder is discharged again, only the diamond powder and A small amount of mixed liquid will be discharged together, while the mixed liquid in the washing tank 1 will not be affected, avoiding a large amount of mixed liquid and diamond micropowder from flowing out together, which not only increases the workload of subsequent filtration and separation, but also makes it impossible to effectively recycle the mixed liquid. Since the volume of the storage space 7002 is smaller than the volume of the height difference between the drainage trough 1001 and the feed pipe 4 in the washing tank 1, the diamond micropowder in the washing tank 1 is avoided from entering the storage space 7002. The liquid level of the washing tank 1 drops to the feed pipe 4, causing the discharged mixed liquid and diamond micropowder to contact with suspended impurities. After the diamond micropowder in the storage space 7002 is discharged, the diamond micropowder can be continued to be discharged for washing.

[0040] Considering that when the diamond powder accumulates in the storage space 7002, it can only enter the storage space 7002 by gravity and its own fluidity, and the feed trough 7001 is opened on the side of the storage space 7002, the diamond powder will be preferentially accumulated on the side of the storage space 7002 when discharged, so that the middle area of ​​the storage space 7002 cannot be fully filled, resulting in the area of ​​the storage space 7002 that cannot be filled with diamond powder being filled with mixed liquid, and the discharge of mixed liquid and diamond powder together is not minimized, and the discharge pipe 8 and the lifting cylinder are not connected. 7 is slidably connected, and the discharge pipe 8 is restricted by the hollow block 111, so that when the lifting cylinder 7 rises, it cannot drive the discharge pipe 8 to rise, and the discharge pipe 8 will remain in place, so that after the lifting cylinder 7 rises, the storage space 7002 becomes larger, and when the lifting cylinder 7 descends, the storage space 7002 will gradually decrease. When the lifting cylinder 7 descends, it will squeeze the mixed liquid to discharge the mixed liquid from the storage space 7002, and can squeeze the diamond micropowder to completely fill the storage space 7002, thereby facilitating the subsequent separation of the diamond micropowder from the mixed liquid after it is discharged.

[0041] When the lifting cylinder 7 descends and the storage space 7002 gradually decreases, the excess mixed liquid is squeezed out. If the amount of diamond powder entering the storage space 7002 is large, the lifting cylinder 7 will descend to squeeze the diamond powder. However, since there is no large amount of mixed liquid in the storage space 7002, the diamond powder cannot be further compressed, and the fluidity of the diamond powder is poor, and it cannot be smoothly squeezed out from the feed trough 7001. There is a situation where the diamond powder presses against the top wall of the lifting cylinder 7, causing the lifting cylinder 7 to be unable to smoothly descend back to its original position. Therefore, when the mixed liquid is lifted, the diamond powder will not be squeezed out. After the lowering cylinder 7 is extruded and the upper side of the inner wall of the lifting cylinder 7 contacts the diamond micropowder, the lifting cylinder 7 continues to descend and will squeeze the discharge pipe 8 through the diamond micropowder, causing the discharge pipe 8 to descend and squeeze the spring 112. The spring 112 will be in a compressed state. At this time, the size of the storage space 7002 remains unchanged, but the storage space 7002 as a whole will be in a descending state, so that the lifting cylinder 7 can normally descend back to its original position to avoid the diamond micropowder getting stuck in the lifting cylinder 7, causing the storage space 7002 to be connected to the washing tank 1, so that a large amount of mixed liquid is discharged, affecting the subsequent separation of diamond micropowder.

[0042] Example 2: Based on Example 1, Figure 2-Figure 4 As shown, a push plate 211 is also included; the push plate 211 is fixedly connected to the lower side of the stirring plate 3, and the lower end of the push plate 211 corresponds to the position of the feed trough 7001. The push plate 211 pushes the diamond powder to improve the fluidity of the diamond powder in the feed trough 7001.

[0043] The specific working steps are:

[0044] When the diamond micropowder is discharged into the storage space 7002 through the feed trough 7001, the motor 2 drives the push plate 211 to rotate slowly through the stirring plate 3. At this time, the push plate 211 will push the diamond micropowder at the feed trough 7001 and push the diamond micropowder at the feed trough 7001 into the storage space 7002, thereby improving the fluidity of the diamond micropowder at the feed trough 7001, avoiding the diamond micropowder from being stuck between the lifting cylinder 7 and the washing tank 1, making it inconvenient for the lifting cylinder 7 to descend, and speeding up the discharge efficiency; it should be noted that when the motor 2 drives the push plate 211 to rotate through the stirring plate 3, the stirring plate 3 drives the push plate 211 to rotate slowly, thereby avoiding the stirring plate 3 from rotating rapidly to stir the mixed liquid and accumulated diamond micropowder in the washing tank 1, affecting the discharge of diamond micropowder.

[0045] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
