Description

Technical Field

[0001] This utility model relates to the field of ammonium perchlorate processing, and in particular to an ammonium perchlorate centrifuge device that is tilted and avoids feed blockage. Background Technology

[0002] Ammonium perhydrogenate is a white crystalline solid that is hygroscopic. It is a strong oxidizing agent. It can explode when mixed with reducing agents, organic matter, flammable materials such as sulfur, phosphorus, or metal powders. Contact with strong acids poses a risk of combustion and explosion. It is used in the manufacture of explosives and fireworks, and as an analytical reagent. Ammonium perhydrogenate requires centrifugation during the production process.

[0003] In existing rotary centrifuges, when the mixed raw materials are poured out, some of the powdery raw materials will stick to the inner wall of the centrifuge, which can easily cause residue and requires secondary cleaning by personnel, which is quite cumbersome.

[0004] Therefore, it is necessary to propose a tilting ammonium perchlorate centrifuge device that avoids feed blockage in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tilting ammonium perchlorate centrifuge that avoids feed blockage, in order to solve the problem in the existing tilting centrifuge where, when the mixed raw materials are tilted, some powdery raw materials will adhere to the inner wall of the centrifuge, which is easy to cause residue and requires personnel to clean it again later, which is quite cumbersome.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tilting ammonium perchlorate centrifuge device that avoids feed blockage, comprising a support frame, two of which are arranged in parallel, a centrifuge cylinder being rotatably connected between the two support frames, and a cylinder cover being detachably connected to the top of the centrifuge cylinder;

[0007] The bottom ends of the two support frames are fixed with base frames. Support blocks are provided inside the base frames for vertical extension. The top of the support blocks is provided with a slot corresponding to the outside of the centrifuge. Multiple vibrators are embedded inside the slot.

[0008] Preferably, an electric push rod is fixed to one side of the support block, a connecting rod is fixed to one end of the electric push rod, a spring is fixedly connected to the top of the connecting rod near the centrifuge cylinder, and a striking ball is fixedly connected to one end of the spring.

[0009] Preferably, a base block is fixed inside the base frame, and multiple hydraulic cylinders are embedded in the top of the base block, with the bottom end of the support block fixed to the multiple hydraulic cylinders.

[0010] Preferably, each of the two support frames is fixed with a shaft retainer at its top, and two rotating shafts are fixed in the middle of the outer side of the centrifuge tube. The two rotating shafts are rotatably connected to the inside of the corresponding shaft retainers. A support plate is fixed at the top of one side of the base frame, and a second motor is fixed at the top of the support plate. The drive shaft of the second motor is fixedly connected to one end of one of the rotating shafts.

[0011] Preferably, a first motor is fixed to the top of the cylinder cover, the drive shaft of the first motor extends into the interior of the centrifuge cylinder, and multiple stirring shafts are fixed to the outer side of the extension end of the drive shaft.

[0012] Preferably, the bottom of the centrifuge cylinder is higher than the bottom of the support frame.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. In the actual operation of this utility model, after the centrifuge drum has finished mixing, the top of the centrifuge drum can be tilted downward by the second motor, so that the raw materials inside can fall automatically along the tilt angle after the drum cover is opened. When the centrifuge drum is tilted, the hydraulic cylinder can be activated to drive the support block to rise, so that the slot and the outside of the centrifuge drum are in contact, thereby supporting the centrifuge drum, ensuring the stability of the centrifuge drum and avoiding shaking.

[0015] 2. Furthermore, once the centrifuge drum is supported and fixed, the vibration generated by the vibrator is transmitted to the centrifuge drum, which facilitates the downward discharge of raw materials adhering to the inner wall of the centrifuge drum, thus avoiding adhesion and reducing residue.

[0016] 3. After the centrifuge tube and support block are fixed, the electric push rod is continuously extended and retracted, causing the connecting plate to drive the striking ball to impact the outside of the centrifuge tube. The vibration of the impact further enhances the discharge speed of the raw materials inside the centrifuge tube, and the spring can increase the shaking amplitude of the striking ball.

[0017] 3. The centrifuge tube is detachably connected to a cap. Since the diameter of the centrifuge tube top and the cap are the same, when the cap is fully opened, the top of the centrifuge tube is completely exposed, allowing ammonium perchlorate raw material to be directly fed into the centrifuge tube. Compared with traditional pipeline transportation, the centrifuge tube top has a larger radius, making direct pouring less prone to clogging, and allowing for the pouring of more raw material at once.

[0022] This utility model provides, for example Figures 1-3 The illustrated tipping-type ammonium perchlorate centrifuge device, which avoids feed blockage, includes a support frame 1. Two support frames 1 are arranged in parallel, and a centrifuge cylinder 4 is rotatably connected between the two support frames 1. A cylinder cover 5 is detachably connected to the top of the centrifuge cylinder 4. Since the top of the centrifuge cylinder 4 and the cylinder cover 5 have the same diameter, when the cylinder cover 5 is fully opened, the top of the centrifuge cylinder 4 is completely exposed, and the ammonium perchlorate raw material can be directly fed into the centrifuge cylinder 4. Compared with traditional pipeline transportation, the top radius of the centrifuge cylinder 4 is larger, and the direct pouring method is less prone to blockage, and more raw material can be poured at one time.

[0023] The centrifuge cylinder 4 and the cylinder cover 5 can be fixed with bolts or snap-fit ​​to achieve a sealed connection. Since this is existing technology, it will not be described in detail.

[0024] Two support frames 1 are fixed to the bottom of the base frame 2. The base frame 2 is equipped with support blocks 10 that extend and retract vertically. The top of the support block 10 is provided with a slot 11 corresponding to the outside of the centrifuge cylinder 4. Multiple vibrators 12 are embedded inside the slot 11.

[0025] Two support frames 1 are each fixed with a shaft retainer at the top. Two rotating shafts 3 are fixed in the middle of the outer side of the centrifuge cylinder 4. The two rotating shafts 3 are rotatably connected to the inside of the corresponding shaft retainer. A support plate 8 is fixed at the top of one side of the base frame 2. A second motor 7 is fixed at the top of the support plate 8. The drive shaft of the second motor 7 is fixedly connected to one end of one of the rotating shafts 3.

[0026] The base frame 2 can increase the height of the support frame 1, and provide sufficient space and height for placing the base block 9 and the support block 10.

[0027] It should be noted that when the hydraulic cylinder is in the retracted state, there is a certain distance between the top of the support block 10 and the centrifuge cylinder 4. This is to prevent the support block 10 from obstructing the centrifuge cylinder 4 when it is rotating.

[0028] In the actual operation of this utility model, when the second motor 7 is started, it can drive the centrifuge cylinder 4 to rotate between the two support frames 1. At this time, since the top of the centrifuge cylinder 4 and the cylinder cover 5 are connected, the centrifugal force of rotation can accelerate the mixing of the ammonium perchlorate raw material inside. Moreover, the integral rotation can avoid uneven mixing between the upper and lower layers of the raw material.

[0029] An electric push rod 13 is fixed to one side of the support block 10. A connecting rod 14 is fixed to one end of the electric push rod 13. A spring 15 is fixedly connected to the top of the connecting rod 14 near the centrifuge cylinder 4. A striking ball 16 is fixedly connected to one end of the spring 15.

[0030] The base frame 2 has a base block 9 fixed inside, and multiple hydraulic cylinders are embedded in the top of the base block 9. The bottom of the support block 10 is fixed to the multiple hydraulic cylinders.

[0031] In the actual operation of this utility model, after the centrifuge cylinder 4 has finished mixing, the top of the centrifuge cylinder 4 can be tilted downward by the second motor 7, so that the raw materials inside can fall automatically along the tilt angle after the cylinder cover 5 is opened. When the centrifuge cylinder 4 is tilted, the hydraulic cylinder can be activated to drive the support block 10 to rise, so that the slot 11 and the outer side of the centrifuge cylinder 4 are in contact, thereby completing the support of the centrifuge cylinder 4, ensuring the stability of the centrifuge cylinder 4 and avoiding shaking.

[0032] Furthermore, once the centrifuge cylinder 4 is supported and fixed, the vibration generated by the vibrator 12 is transmitted to the centrifuge cylinder 4, which facilitates the downward discharge of raw materials adhering to the inner wall of the centrifuge cylinder 4, thereby avoiding adhesion and reducing residue.

[0033] Furthermore, once the centrifuge cylinder 4 and the support block 10 are fixed, the electric push rod 13 extends and retracts continuously, causing the connecting plate 14 to drive the striking ball 16 to impact the outside of the centrifuge cylinder 4. The vibration of the impact further enhances the discharge speed of the raw materials inside the centrifuge cylinder 4, and the spring 15 can increase the shaking amplitude of the striking ball 16.

[0034] The top of the cylinder cover 5 is fixed with a first motor 6. The drive shaft of the first motor 6 extends into the interior of the centrifuge cylinder 4, and multiple stirring shafts are fixed on the outside of the extension end of the drive shaft. The bottom of the centrifuge cylinder 4 is higher than the bottom of the support frame 1.

[0035] In the actual operation of this utility model, the first motor 6 is started, and the internal raw materials can be stirred and mixed through multiple stirring shafts. Combined with the rotation of the centrifuge cylinder 4 itself, the mixing efficiency can be improved.
