Description

Technical Field

[0001] This utility model relates to the field of ammonium persulfate production technology, and in particular to a centrifugal device for producing ammonium persulfate. Background Technology

[0002] Ammonium persulfate's core functions are as a strong oxidant and free radical initiator, and it is widely used in chemical, metal processing, and food industries. It can also be used in water treatment, bleaching and desizing in the textile industry, and as a chemical reagent in laboratories.

[0003] A search revealed that the utility model patent with authorization announcement number CN221656861 U discloses a centrifugal device for producing ammonium persulfate. Although the device can separate and dry solid materials, the subsequent output of solid materials is slow due to the limitations of the discharge pipe structure. This also leads to solid material residue inside the centrifuge, resulting in unsatisfactory output performance.

[0004] Therefore, it is necessary to invent a centrifugal device for producing ammonium persulfate to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a centrifugal device for producing ammonium persulfate, which can accelerate the output speed of solid materials from the inside of the centrifugal cylinder by utilizing centrifugal action, and at the same time, can discharge more comprehensively, thereby reducing material residue and achieving more ideal practical results. This solves the problem mentioned in the background art that, due to the limitation of the discharge pipe structure, the subsequent output of solid materials is not only slow, but also easily leads to solid material residue inside the centrifugal cylinder, resulting in unsatisfactory actual performance.

[0006] According to one aspect of this disclosure, a centrifugal apparatus for producing ammonium persulfate is provided, comprising:

[0007] A housing assembly, which provides a mounting base for the centrifugal drying assembly and the plugging adjustment mechanism;

[0008] A centrifugal drying assembly, used for centrifuging raw materials and drying solid materials; and

[0009] The sealing and adjusting mechanism includes a fixed ring fixedly sleeved on the top of the outer side of the centrifuge mesh cylinder. Multiple guide rods A are evenly slidably inserted through the top of the fixed ring in a vertical direction. The bottom ends of the multiple guide rods A are jointly fixedly connected to a sealing plate that seals the bottom opening of the centrifuge mesh cylinder. A movable disc is rotatably nested at the bottom center of the sealing plate via a bearing. Guide rods B are fixedly installed on both sides of the bottom of the fixed ring, sliding vertically through the centrifuge vessel and the flow guide seat. The sealing and adjusting mechanism also includes an electric push rod fixedly installed at the bottom center of the centrifuge vessel. The output shaft of the electric push rod slides vertically through the bottom of the centrifuge vessel and the flow guide seat, and is fixedly connected to the bottom center of the movable disc.

[0010] According to at least one embodiment of the present disclosure, a centrifugal apparatus for producing ammonium persulfate includes a centrifuge vessel, wherein a flow guide seat is fixedly disposed at the bottom of the inner cavity of the centrifuge vessel.

[0011] According to at least one embodiment of the present disclosure, a centrifugal apparatus for producing ammonium persulfate has a feed pipe fixedly provided through the top right side of the centrifugal vessel, extending above the centrifugal mesh cylinder, and an exhaust pipe fixedly provided through the top left side of the centrifugal vessel.

[0012] According to at least one embodiment of the present disclosure, a centrifugal apparatus for producing ammonium persulfate has a discharge pipe fixedly disposed through the bottom front of the centrifugal vessel, and a transparent observation window is fixedly nested in the front of the centrifugal vessel.

[0013] According to at least one embodiment of the present disclosure, a centrifugal apparatus for producing ammonium persulfate includes a centrifugal drying assembly comprising a servo motor fixedly disposed at the center of the top of a centrifuge vessel, the output shaft of the servo motor extending into the interior of the centrifuge vessel and fixedly connected to a connecting frame, and a centrifugal mesh sleeve fixedly sleeved on the outside of the connecting frame.

[0014] According to at least one embodiment of the present disclosure, a centrifugal apparatus for producing ammonium persulfate has an air inlet pipe fixedly disposed on the top left side of the centrifugal vessel, extending above the centrifugal mesh cylinder, and a hot air fan fixedly disposed on the top of the centrifugal vessel is provided on the air inlet pipe.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention incorporates a sealing adjustment mechanism. During the continuous rotation of the sealing plate due to centrifugation, the movable disc remains stationary via bearings. After centrifugation and solid material separation, the servo motor is stopped, and the electric push rod drives the movable disc, guided by guide rod B, to move downwards. This downward movement of the movable disc causes the sealing plate, guided by guide rod A, to move downwards as well, thus releasing the seal on the bottom opening of the centrifuge cylinder. At this point, the solid material falls to the top of the sealing plate under gravity. The servo motor is then restarted, causing the sealing plate to rotate synchronously. The solid material is then thrown to the top of the guide seat during the rotation of the sealing plate and output through the discharge pipe. Compared to existing technologies, this invention utilizes centrifugation to accelerate the output speed of solid material from the inside of the centrifuge cylinder, resulting in more comprehensive discharge and reduced material residue. The actual performance is more ideal. Attached Figure Description

[0027] Figure 2 This is a partial structural diagram of the housing component 1 and the centrifugal drying component 2 of a centrifugal apparatus for producing ammonium persulfate according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the structure of the centrifugal drying component 2 and the partial blocking adjustment mechanism 3 of a centrifugal apparatus for producing ammonium persulfate according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the centrifugal device for producing ammonium persulfate disclosed herein may include components such as a housing component 1, a centrifugal drying component 2, and a sealing and adjusting mechanism 3. The overall material of the device is preferably stainless steel 304 / 316L. Ammonium persulfate is weakly corrosive, and this material can prevent the equipment from rusting. Core moving parts, such as bearings and drive components, are all selected from industrial-grade wear-resistant parts to ensure long-term stable operation.

[0030] like Figure 2As shown in this disclosure, the housing component 1 provides a sealed installation space for the entire device, and simultaneously realizes the introduction, export and exhaust of materials and the emission of waste gas. Specifically, it includes a centrifuge vessel 11, which is made of 316L stainless steel and can withstand the corrosion of ammonium persulfate solution. A guide seat 12 is fixedly installed at the bottom of the inner cavity of the centrifuge vessel 11. A feed pipe 13, made of stainless steel, is fixedly installed through the top right side of the centrifuge vessel 11 and extends to the top of the centrifuge screen cylinder 23. An exhaust pipe 14 is fixedly installed through the top left side of the centrifuge vessel 11. A discharge pipe 15 is fixedly installed through the bottom front of the centrifuge vessel 11. Valves are installed on the feed pipe 13, exhaust pipe 14 and discharge pipe 15 to adjust the opening and closing of multiple valves according to the progress of the centrifugation process. A transparent observation window 16, made of tempered borosilicate glass, is fixedly nested on the front of the centrifuge vessel 11. It is resistant to high temperature and impact.

[0031] Therefore, the liquid and solid materials can be guided sequentially through the guide seat 12, so that they can be output better and residues can be reduced. The liquid raw material is fed into the centrifuge cylinder 23 through the feed pipe 13, the waste gas generated during drying is discharged through the exhaust pipe 14, and the liquid and solid materials guided by the guide seat 12 are discharged sequentially through the discharge pipe 15. The working condition inside the centrifuge 11 during the centrifugation process can be observed through the transparent observation window 16.

[0032] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the centrifugal drying assembly 2, through an integrated design of "centrifugal separation + hot air drying," completes the solid-liquid separation and solid material drying of ammonium persulfate raw material. Specifically, it includes a servo motor 21 fixedly mounted at the top center of the centrifuge tank 11, with a preferred power of 1.5-2.2kW and an adjustable speed, specifically within the range of 500-1500 r / min. The output shaft is rigidly connected to the connecting frame 22 via a coupling, allowing the speed to be adjusted according to the raw material concentration. For example, when the raw material has a high solid content, the speed is adjusted to 800-1000 r / min to avoid overloading the centrifugal screen 23. The output shaft of the servo motor 21 extends into the centrifuge vessel 11 and is fixedly connected to a connecting frame 22. A centrifuge mesh cylinder 23 is fixedly sleeved on the outside of the connecting frame 22. It is a cylindrical mesh structure with a diameter of 300-500mm, a height of 600-800mm, and a mesh size of 0.1-0.2mm, allowing only liquid and small molecule impurities to pass through while trapping ammonium persulfate solid particles. An air inlet pipe 24 is fixedly installed on the top left side of the centrifuge vessel 11, extending above the centrifuge mesh cylinder 23. A hot air fan 25 is fixedly installed on the air inlet pipe 24 and fixedly mounted on the top of the centrifuge vessel 11, with an air volume of 80-120m³. 3 / h, the outlet air temperature is adjustable (range 50-80℃). Since ammonium persulfate is easily decomposed (releasing oxygen and sulfuric acid) at temperatures >100℃, the drying temperature must be strictly controlled below 80℃ to avoid product deterioration.

[0033] Therefore, after the liquid raw material enters the centrifugal mesh cylinder 23 through the feed pipe 13, the liquid material can only pass through the filter holes on the surface of the centrifugal mesh cylinder 23 for output because the bottom opening of the centrifugal mesh cylinder 23 is sealed by the sealing plate 33. Subsequently, the servo motor 21, which is powered on, drives the centrifugal mesh cylinder 23 to rotate continuously through the connecting frame 22, thereby using centrifugal action to accelerate the output speed of the liquid material. During this process, the solid material remains inside the centrifugal mesh cylinder 23. When the centrifugal mesh cylinder 23 rotates, it drives multiple guide rods A32 to rotate through the fixing ring 31. The guide rods A32 drive the sealing plate 33 to rotate synchronously with the centrifugal mesh cylinder 23, thereby keeping the sealing plate 33 sealed to its bottom opening during the rotation of the centrifugal mesh cylinder 23.

[0034] After centrifugation, the powered hot air blower 25 draws in outside air through the air inlet pipe 24 and heats it. Then, it is input into the centrifuge mesh cylinder 23 through the air inlet pipe 24 and forms a columnar airflow, which dries the solid material inside the centrifuge mesh cylinder 23. The waste gas generated during the drying process is output to the exhaust gas treatment equipment through the exhaust pipe 14 for treatment.

[0035] like Figure 3 As shown in this disclosure, the sealing and adjusting mechanism 3 solves the shortcomings of slow discharge and excessive residue in traditional devices through an innovative structure of "dynamic sealing - controllable opening - centrifugal discharge". Specifically, it includes a fixed ring 31, which is a stainless steel circular ring, fixedly sleeved on the top of the outer side of the centrifugal screen cylinder 23. The inner diameter of the ring is welded to the outer side of the centrifugal screen cylinder 23. Multiple guide rods A32 are uniformly slidably installed on the top of the fixed ring 31 in the vertical direction. The bottom ends of the multiple guide rods A32 are all fixedly connected to a sealing plate 33, which is a circular stainless steel plate, to seal the bottom opening of the centrifugal screen cylinder 23. A silicone sealing ring is installed on the top. Under normal conditions, the sealing plate 33 seals the opening of the centrifugal screen cylinder 23 through the silicone sealing ring. The bottom of the mesh cylinder 23 is fitted to achieve a seal, preventing liquid leakage during centrifugation and catching falling solid materials when opened. The bottom center of the sealing plate 33 is nested with a movable disc 34 through a bearing. Both sides of the bottom of the fixed ring 31 are fixed with guide rods B35 that slide vertically through the centrifuge vessel 11 and the guide seat 12. The sealing adjustment mechanism 3 also includes an electric push rod 36 fixedly set at the bottom center of the centrifuge vessel 11. An industrial-grade electric push rod (model DTZ1000) is selected. The output shaft of the electric push rod 36 slides vertically through the bottom of the centrifuge vessel 11 and the guide seat 12 and is fixedly connected to the bottom center of the movable disc 34.

[0036] Therefore, during the continuous rotation of the sealing plate 33 due to centrifugation, the movable disk 34 remains stationary through the bearing. After the centrifugation ends and the solid material is separated, the servo motor 21 is stopped, and the electric push rod 36 drives the movable disk 34, guided by the guide rod B35, to move continuously downward. When the movable disk 34 moves downward, it drives the sealing plate 33, guided by the guide rod A32, to move continuously downward, thereby releasing the blockage of the bottom opening of the centrifugal mesh cylinder 23. At this time, the solid material falls to the top of the sealing plate 33 under the action of gravity. Then, the servo motor 21 is restarted, and the sealing plate 33 is driven to rotate synchronously. The solid material is thrown to the top of the guide seat 12 during the rotation of the sealing plate 33, and then output through the discharge pipe 15. Compared with the existing technology, the centrifugal action can be used to speed up the output of solid material from the inside of the centrifugal mesh cylinder 23, and the output can be more comprehensive, thereby reducing material residue. The actual use effect is more ideal.
