Description

Technical Field

[0001] The 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; Add appropriate amount of water and detergent to the mixing tank to get the mixed liquid, then add diamond powder, use mechanical stirring to separate diamond powder from impurities, and the lighter impurities will be suspended in the mixed liquid and discharged by overflow, while the heavier diamond powder will settle at the bottom, and then the diamond powder can be discharged from the bottom; When discharging diamond powder from the stirring tank washing machine in the above-mentioned method, 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

[0003] In order to overcome the disadvantages that direct discharge of diamond powder will cause the mixed liquid and the powder to mix, increase the separation burden, waste the mixed liquid, and increase the cost, the present invention provides an overflow grading diamond powder washing machine.

[0004] 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 liquid discharge 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; all the telescopic parts of the electric push rods are commonly fixedly connected to the lifting cylinder; the lifting cylinder is provided with a number of 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.

[0005] More preferably, the lower side of the feed trough is inclined.

[0006] More preferably, the feed pipe and the liquid inlet pipe are respectively located below the liquid drain trough.

[0007] More preferably, a sealing strip is provided between the outer side of the lifting cylinder and the washing tank.

[0008] 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.

[0009] More preferably, it further comprises a hollow block; the bottom of the washing tank is fixedly connected with the hollow block; and the hollow block is slidably connected with the discharge pipe.

[0010] More preferably, it further comprises 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.

[0011] More preferably, a guide plate is further included; the guide plate is fixedly connected to the drain groove of the washing tank.

[0012] More preferably, it further includes an observation window; the front part of the washing tank is fixedly connected with the observation window, and the observation window is a glass window.

[0013] 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.

[0014] Compared with the prior art, the present invention has the following advantages: 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, thereby avoiding a large amount of mixed liquid and diamond micropowder from 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.

[0015] 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 contact with suspended impurities; after the diamond micropowder in the storage space is discharged, the diamond micropowder can continue to be discharged for washing.

[0016] 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 can squeeze the diamond micropowder to completely fill the storage space, thereby facilitating the subsequent separation of the diamond micropowder from the mixed liquid after it is discharged.

[0017] After the upper side of the inner wall of the lifting cylinder contacts the diamond micro-powder, the lifting cylinder will continue to descend and squeeze the discharge pipe through the diamond micro-powder, 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 to avoid the diamond micro-powder 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 micro-powder.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0021] Embodiment 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 feed 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 feed 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 liquid drain trough 1001 for discharging suspended impurities; the motor 2 is connected to an external power supply; 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 the electric push rods 6 are commonly fixedly connected to the lifting cylinder 7; the lifting cylinder 7 is provided with four feeding 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.

[0022] The lower side of the feed trough 7001 is inclined to facilitate the discharge of diamond powder into the storage space 7002 and to prevent diamond powder from remaining when the diamond powder is discharged from the storage space 7002 if the lower side of the feed trough 7001 is flat.

[0023] The feed pipe 4 and the liquid inlet pipe 5 are respectively located below the liquid discharge tank 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.

[0024] A sealing strip is provided between the outer side of the lifting cylinder 7 and the washing tank 1 .

[0025] The volume of the storage space 7002 is smaller than the volume of the height difference between the drain trough 1001 and the feed pipe 4 in the washing tank 1, so as to prevent the liquid level of the washing tank 1 from dropping to the feed pipe 4 after the diamond powder in the washing tank 1 enters the storage space 7002, causing the discharged mixed liquid and diamond powder to contact with suspended impurities.

[0026] It also includes a hollow block 111 ; the bottom of the washing tank 1 is fixedly connected with the hollow block 111 ; the hollow block 111 is slidably connected with the discharge pipe 8 .

[0027] 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.

[0028] 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 and discharged into the external collection device through the guide plate 101.

[0029] 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 , and the observation window 102 is a glass window, through which the deposition and discharge of the diamond powder in the washing tank 1 can be observed.

[0030] The specific working steps are: The external feeding device is connected to the feeding pipe 4, and the external feeding device conveys diamond powder. The external liquid feeding device is connected to the liquid inlet pipe 5, and the external liquid feeding device conveys the mixed liquid. The guide plate 101 is connected to the external collecting device, and a collecting box is placed under the discharge pipe 8.

[0031] When the diamond powder needs to be washed, firstly, the mixed liquid is conveyed to the liquid inlet pipe 5 through the external liquid conveying device, so that the mixed liquid is discharged into the washing tank 1 through the liquid inlet pipe 5, and at the same time, the external feeding device conveys 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, so that the diamond powder and the mixed liquid are mixed. 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 conveying device and the external feeding device will continue to convey the mixed liquid and the diamond powder. When the liquid level of the mixed liquid rises to the drainage tank 1001, the mixed liquid will be discharged from the drainage tank 1001 together with the impurities suspended on the surface of the mixed liquid, and then through The guide plate 101 guides 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 accumulates 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 with 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 stored 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 continue to enter the storage space 7002, a large amount of mixed liquid is prevented from being in the storage space 7002. Then, the lifting cylinder 7 is descended so that the storage space 7002 of the lifting cylinder 7 is no longer connected with the washing tank 1. When discharging the diamond powder, only the diamond powder and A small amount of mixed liquid is 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, it is avoided that after the diamond micropowder in the washing tank 1 enters 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 continue to be discharged for washing.

[0032] 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 slot 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 the mixed liquid and the diamond powder together is not minimized, and the discharge pipe 8 and the lifting cylinder 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, the mixed liquid will be squeezed to discharge the mixed liquid from the storage space 7002, and the diamond micropowder can be squeezed to completely fill the storage space 7002, so as to facilitate the subsequent separation of the diamond micropowder from the mixed liquid after it is discharged.

[0033] 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, making it impossible for the lifting cylinder 7 to smoothly descend back to its original position. Therefore, when the mixed liquid is lifted, the diamond powder is 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 powder, the lifting cylinder 7 continues to descend and squeezes the discharge pipe 8 through the diamond powder, 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 be normally descended back to its original position to avoid the diamond powder getting stuck in the lifting cylinder 7, causing the storage space 7002 to be connected with the washing tank 1, so that a large amount of mixed liquid is discharged, affecting the subsequent separation of diamond powder.

[0034] Embodiment 2: Based on embodiment 1, Figure 2-Figure 4 As shown, it also includes a push plate 211; 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.

[0035] The specific working steps are: When the diamond powder 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 powder at the feed trough 7001, and push the diamond powder at the feed trough 7001 into the storage space 7002, thereby improving the fluidity of the diamond powder at the feed trough 7001, avoiding the diamond powder from being stuck between the lifting cylinder 7 and the washing tank 1, making it inconvenient for the lifting cylinder 7 to descend, and accelerating 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 quickly to stir the mixed liquid and accumulated diamond powder in the washing tank 1, affecting the discharge of the diamond powder.

[0036] 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, all 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.
