Description

Technical Field

[0001] This utility model belongs to the field of potassium nitrate tailings processing technology, specifically relating to a potassium nitrate tailings recovery device. Background Technology

[0002] Potassium nitrate is an inorganic compound used in industrial production and is also commonly known as caustic soda. It is used in many industrial production processes such as agriculture, gunpowder, medicine, and glass, and is a very important industrial raw material. In its production process, it needs to be dried using a vibrating fluidized bed, and then screened using a drum screen. Unqualified large particles need to be sent to a remelting kettle to be dissolved with steam and then recrystallized and dried. This process wastes manpower and resources and increases steam consumption.

[0003] Traditionally, large particles of potassium nitrate tailings are crushed using a crushing mechanism within the recovery unit. However, some particles that are not fully crushed remain stuck on the screen. To ensure the full recovery of potassium nitrate tailings, personnel need to use tools to collect the particles from the screen and return them to the crushing chamber for further crushing. This avoids the influence of larger particles being mixed into the potassium nitrate tailings. However, collecting particles and putting them into the chamber in this way is cumbersome and requires stopping the machine during operation, thus affecting the overall recovery efficiency of potassium nitrate tailings.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention allows personnel to pre-start the second drive motor, which, under the synchronous transmission of the first synchronous pulley, synchronous belt, and second synchronous pulley, rotates the drive shaft and one of the pulleys connected to its end. The belt around this pulley, in conjunction with another driven pulley, drives the surrounding hoppers in a cyclical reciprocating motion. This cyclically transports the potassium nitrate tail particles introduced into the mounting frame. When transported to the upper section of the mounting frame, the movement of the belt naturally discharges the particles from the hoppers into the discharge area. Since the discharge area connects to the fixed frame, the particles are guided by the inclined guides segmented within the fixed frame, allowing them to continue being fed into the final connecting frame and smoothly and evenly discharged into the processing area of ​​the crushing mechanism along the distributed guides. This seamlessly achieves the continued re-crushing of particles that were not fully ground and recovered by the previous wheel. This process requires no human intervention, is portable and practical, and improves the crushing and recovery rate.

[0018] In this invention, the operator first feeds the potassium nitrate tail powder material mixed with particles into the feed inlet at the top of the main body. Under the drive of the first drive motor, the second crushing roller can cooperate with the first crushing roller in a fixed state to crush and grind the material. Some of the potassium nitrate tail particles and powder will fall onto the screen. The potassium nitrate tail powder will be directly fed into the screen groove and discharged from the outlet, while the particles will be blocked on the screen and naturally fed into the feeding area of ​​the mounting frame due to the guidance of the guide frame and the inclination of the fixed inclined frame.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a potassium nitrate tailings recovery device, the structural diagram of which is shown below. Figures 1 to 4As shown, the device includes a main body 1, with a feed inlet 2 at its top. A crushing mechanism 3 is installed in the upper part of the main body 1.

A screen 6 is installed in the middle of the fixed inclined frame 5, and guide frames 7 are fixed on both sides above the fixed inclined frame 5. The guide frames 7 are symmetrically arranged along the upper central axis of the fixed inclined frame 5. A discharge port 8 is opened in the lower part of one side of the main body 1, and a mounting frame 9 is fixed on the side of the main body 1. A directional guide mechanism 10 is installed on the inner and outer sides of the mounting frame 9. The crushing mechanism 3 includes a first crushing roller 31, which is fixed on one side of the inside of the main body 1. A second crushing roller 32 is installed on the other side of the inside of the main body 1, and one end of the second crushing roller 32 is connected to... A transmission rod 33 is connected to a first drive motor 34 at one end. A fixed frame 35 is fixed around the first drive motor 34. The first crushing roller 31 is fixedly connected to the main body 1. The operator pre-introduces the potassium nitrate tail powder mixed with particles into the feed port 2 at the top of the main body 1. Under the drive of the first drive motor 34, the second crushing roller 32 can cooperate with the fixed first crushing roller 31 to crush and grind the material. Some of the potassium nitrate tail particles and powder will fall onto the screen 6. The potassium nitrate tail powder will be directly introduced into the screen groove and discharged from the discharge port 8, while the particles will be blocked on the screen 6 and naturally introduced into the feed area 101 of the mounting frame 9 due to the guidance of the guide frame 7 and the inclination of the fixed inclined frame 5.

[0028] The directional feeding mechanism 10 includes a feeding area 101, and a discharge area 102 is provided on one side of the bottom of the mounting frame 9 and on one side of the upper section of the mounting frame 9. A circulating conveying assembly 103 is installed inside the mounting frame 9. The circulating conveying assembly 103 includes pulleys 1031, which are located in the upper and lower sections inside the mounting frame 9. Belts 1033 are fitted around the periphery of the two pulleys 1031, and one end of one of the pulleys 1031 is connected to a drive shaft 1032. A first synchronous pulley 1035 is fixed around the periphery of the drive shaft 1032, and a synchronous belt 1 is fitted around the periphery of the first synchronous pulley 1035. 036, a second synchronous pulley 1037 is attached to the inner edge of the other side of the synchronous belt 1036, and the inner side of the second synchronous pulley 1037 is fixed to the periphery of the output end of the second drive motor 1038. Hoppers 1034 are fixedly arranged around the periphery of the belt 1033, and the hoppers 1034 are equidistantly arranged along the periphery of the belt 1033. A guide assembly 104 is mounted on the outside of the mounting frame 9. The guide assembly 104 includes a fixing frame 1041, which is fixed to one side of the mounting frame 9. An inclined guide frame 1042 is fixed inside the fixing frame 1041. An end connecting frame 1043 is connected to the end of the fixing frame 1041. The middle section is equipped with a spreading guide frame 1044. Multiple spreading guide frames 1044 are provided, and the ends of the multiple spreading guide frames 1044 point in different directions. The second drive motor 1038 is pre-started by personnel. Under the synchronous transmission of the first synchronous pulley 1035, the synchronous belt 1036, and the second synchronous pulley 1037, the drive shaft 1032 and one of the pulleys 1031 connected to its end can rotate. Thus, the belt 1033 surrounding this pulley 1031, in conjunction with another driven pulley 1031, drives the surrounding hoppers 1034 in a cyclical reciprocating motion, thereby guiding the potassium nitrate tailings into the mounting frame 9. The particles are transported in a cycle. When they reach the upper section of the mounting frame 9, the movement of the belt 1033 will naturally cause the particles in the hopper 1034 to be fed into the discharge area 102. Since the discharge area 102 is connected to the fixed frame 1041, the particles can be guided by the inclined guide frames 1042 set in sections within the fixed frame 1041 to continue to be fed into the final connecting frame 1043 and smoothly and evenly discharged into the processing area of ​​the crushing mechanism 3 along the evenly distributed guide frames 1044. In this way, the particles that have not been ground and recovered by the previous wheel can be re-crushed without any human intervention. This process is portable and practical while improving the crushing and recovery rate.

[0029] Working principle: Workers pre-feed potassium nitrate tail powder mixed with particles into the feed inlet 2 at the top of the main body 1. Driven by the first drive motor 34, the second crushing roller 32, in conjunction with the fixed first crushing roller 31, crushes and grinds the material. Some potassium nitrate tail particles and powder fall onto the screen 6. The potassium nitrate tail powder is directly fed through the screen groove and discharged from the outlet 8, while the particles are blocked on the screen 6 and naturally fed into the feed area 101 of the mounting frame 9 due to the guidance of the guide frame 7 and the inclination of the fixed inclined frame 5. In this state, the second drive motor 1038 is pre-started. Under the synchronous transmission of the first synchronous pulley 1035, the synchronous belt 1036, and the second synchronous pulley 1037, the drive shaft 1032 and one of the pulleys 1031 connected to its end rotate. The belt 1033 around the wheel 1031 can work with another driven belt pulley 1031 to drive the peripherally distributed hoppers 1034 to reciprocate in a cyclical motion. This allows the potassium nitrate tail particles introduced into the mounting frame 9 to be transported in a cyclical manner. When transported to the upper section of the mounting frame 9, the particles in the hoppers 1034 will be naturally thrown into the discharge area 102 due to the movement of the belt 1033. Since the discharge area 102 is connected to the fixed frame 1041, the particles can be guided by the inclined guide frames 1042 in the fixed frame 1041 to continue to be introduced into the end frame 1043 and smoothly and evenly discharged into the processing area of ​​the crushing mechanism 3 along the distributed even guide frames 1044. This allows for seamless re-crushing of the particles that have not been ground and recovered by the upper wheel. This process does not require personnel intervention, is portable and practical, and improves the crushing and recovery rate.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
