The outer wall of the concave box 5 is fixedly connected with a plurality of sliding columns 10, which drive the concave block to move synchronously when the vibrating block 4 moves transversely, thereby driving the sliding columns 10 to move, the outer walls of the two sliding columns 10 are slidingly connected with the inner walls of the fixed piles 9, the outer sides of the sliding columns 10 are sleeved with springs 11, one end of the plurality of springs 11 is fixedly connected with the outer wall of the fixed pile 9, the springs 11 are extruded and stretched by the movement of the sliding columns 10, so that the movement of the concave block has a reverse elastic force, thereby ensuring the vibration stability of the concave block and the vibrating block 4 in the transverse direction.

[0034] The inside of the vibrating block 4 is fixedly connected with a driving column 12, the two ends of the driving column 12 are respectively fixedly connected with two half cams 13, due to the special shape of the half cam 13, it provides an upward reverse force and a transverse friction force when it is in contact with the bottom plate 8.

[0035] Referring to Figure 1 , Figure 2 , Figure 4The acid washing assembly comprises a feeding cylinder 16 for feeding the diamond powder into the purification cylinder 1, the bottom of the feeding cylinder 16 is fixedly connected to the top of the purification cylinder 1, so as to avoid the problems of blockage or leakage during the conveying process. The top of the purification cylinder 1 is fixedly connected with a plurality of acid washing cylinders 17, three of which store dilute sulfuric acid, potassium ferrate and concentrated nitric acid respectively, and the other one contains water for flushing. The design of the above four acid washing cylinders 17 enables different acid solutions to be used in sequence to clean and treat the diamond powder, thereby removing the metal impurities and organic pollutants on the surface of the diamond powder. The inner wall of the purification cylinder 1 is fixedly connected with a sieve plate one 18, and the inner wall of the purification cylinder 1 is fixedly connected with a sieve plate two 19. The sieve plate one 18 and the sieve plate two 19 are arranged for grading and screening the diamond powder, so that diamond powders of different particle sizes can be effectively separated, and the acid washing solution can be recycled in the subsequent recycling mechanism. The bottom of the purification cylinder 1 is fixedly connected with a plurality of liquid outlet pipes 23, the other end of the liquid outlet pipe 23 is fixedly connected with a collection cylinder 24, and the collection cylinder 24 is provided with a liquid pumping pump, so that the waste liquid generated in the acid washing process can be discharged in time and collected and treated in the collection cylinder 24 through the liquid outlet pipe 23.

The outer wall of the purification cylinder 1 is fixedly connected with a heater 22, which is used for drying after the artificial diamond is washed.

[0036] The gas collecting assembly comprises an air outlet pipe 25, one end of the air outlet pipe 25 is fixedly connected to the inside of the purification cylinder 1. Because the acid washing process needs to be dried and the heat generated during the acid washing process makes the gas temperature in the purification cylinder 1 too high, the gas molecules inside move upward, so the position of the air outlet pipe 25 is arranged above the purification cylinder 1, and the acidic gas is sucked into the subsequent gas collecting structure through the air outlet pipe 25. The inner wall of the purification cylinder 1 is fixedly connected with a filter plate 26, which is used to prevent some raw materials from entering the air outlet pipe 25 and causing blockage during feeding. The other end of the air outlet pipe 25 is fixedly connected with a gas collecting box 27, and the bottom of the gas collecting box 27 is placed with an alkaline chemical absorbent such as ammonia water, calcium hydroxide, etc. The inner wall of the gas collecting box 27 is fixedly connected with a gas pumping pump 28, which is used to pump the acidic gas in the purification cylinder 1 out of the purification cylinder 1, so as to balance the air pressure inside the purification cylinder 1 and simultaneously concentrate the absorption of the acidic gas, avoiding environmental pollution. The top of the gas collecting box 27 is fixedly connected with a partition plate 29, which is used to separate the chemical absorbent from the gas pumping pump 28 and provide a support point for the gas pumping pump 28.

[0037] Working principle: in use, the diamond powder is transported to the inside of the purification cylinder 1 through the feeding cylinder 16, so that the diamond powder enters the sieve plate 18, the heater 22 is opened, the pickling cylinder 17 containing dilute sulfuric acid is opened, the dilute sulfuric acid enters the purification cylinder 1 and contacts the diamond, and the metal impurities and organic contaminants on the surface of the diamond are removed, then the pickling cylinder 17 containing water is opened, the impurities are cleaned, the heater 22 is dried, then the pickling cylinder 17 containing potassium ferrate is opened, the residual organic matter and metal impurities are further oxidized, then the impurities are removed by water washing, drying, and finally the residual organic matter and metal impurities are cleaned again by concentrated nitric acid, and then removed by water washing again. In this process, the impurities cleaned by pickling in sequence and the cleaning liquid enter three liquid outlets 23 respectively, and are collected by the collection cylinder 24. At the same time, the exhaust pump 28 is opened, a large amount of waste gas generated in the pickling process enters the gas collection tank 27 through the exhaust pipe 25 and the filter plate 26, and is absorbed by the chemical absorbent in the gas collection tank 27, thereby avoiding pollution caused by the emission of acidic gas.

[0038] In the pickling process, the motor 14 is opened, the motor 14 operates to drive the driving column 12 to rotate, thereby driving the two half cams 13 to rotate. Due to the special shape of the half cam 13, an upward reverse force and a transverse friction force are provided when the half cam 13 contacts the bottom plate 8, thereby driving the vibration block 4 to move upward and left and right, thereby extruding the spring 7 at the top, and due to the self-gravity and the elastic force of the spring 7, the vibration block 4 tends to move downward, thereby realizing up-down vibration. The transverse friction force drives the vibration block 4 to move left and right, thereby driving the concave box 5 to move left and right, and further driving the sliding column 10 to slide in the fixed pile 9, compressing the spring 11, and driving the entire concave box 5 to move left and right through the elastic force of the deformation recovery of the spring 11, thereby making the vibration block 4 move left and right in the vertical direction and the horizontal direction, and transmitting to the vibration disc 2 through the transmission column 3, thereby driving the entire purification cylinder 1 to move, so that the sieve plate 18 and the sieve plate 19 in the purification cylinder 1 move, thereby increasing the contact area of the raw material and the acid, thereby improving the purification effect. At the same time, due to the vibration of the sieve plate 18 and the sieve plate 19, diamond powders of different particle sizes are classified. After pickling is completed, the cylinder door 20 can be opened to take out diamond powders of different particle sizes.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application.
