[0041] Specifically, the coarse nitre slurry first enters the cylindrical barrel 1 through the feed pipe 4, which communicates with the cylindrical barrel 1 in a tangent direction, which makes the slurry have a certain tangential velocity when entering the cylindrical barrel 1, so that a rotating motion is rapidly formed in the cylindrical barrel 1. During the rotation of the slurry, a centrifugal force is generated, and the solid particles or the liquid with a larger density begin to move towards the wall of the cylindrical barrel 1 under the action of the centrifugal force. As the slurry continues to flow downward into the conical barrel 3, the rotating motion of the slurry becomes more intense in the conical barrel 3, and the centrifugal force is further enhanced. In the conical barrel 3, the solid particles or the liquid with a larger density are thrown more strongly to the wall and move downward along the wall in a spiral trajectory. At this time, the vortex breaker 7 located at the middle and lower end of the conical barrel 3 effectively changes the flow state of the slurry at the bottom. When the solid material and part of the liquid flow to the underflow outlet, the vortex breaker 7 prevents the formation of vortex and avoids air being sucked into the slurry, which ensures that the solid material can be stably and smoothly discharged through the threaded sand discharge nozzle 8 at the bottom of the conical barrel 3. The clarified liquid or the fine particles carried in the liquid move to the central area of the cylindrical barrel 1 and rise under the action of the centrifugal force. At the top end of the inside of the cylindrical barrel 1, the flow guide cylinder 5 provides a stable channel for the rising liquid, guiding the clarified liquid or the fine particles to move upward smoothly and preventing them from mixing with the surrounding rotating slurry again or causing turbulence during the rising process. Finally, these clarified liquids or fine particles are discharged from the overflow outlet pipe 6 at the top of the cylindrical barrel 1. During the operation of the equipment, the threaded sand discharge nozzle 8 at the bottom of the conical barrel 3 cooperates with the threaded connecting head 10 at the top of the sand collecting tank 9. When it is necessary to discharge the sand particles or other heavy impurities accumulated at the bottom, the operator can use the handles 11 fixed and connected at equal intervals on the outside of the sand collecting tank 9 to rotate the threaded connecting head 10 out of the threaded sand discharge nozzle 8, thereby conveniently cleaning and collecting the impurities such as sand particles. The outer frame 12 fixedly connected to the outside of the cylindrical barrel 1 and the conical barrel 3 plays a role in supporting and protecting the internal components, ensuring the stability and safety of the entire equipment during operation, enabling it to withstand a certain external impact force and working pressure, ensuring the continuous and stable progress of the coarse nitre dehydration process, and enabling the equipment to efficiently realize the solid-liquid separation of the coarse nitre slurry, meeting the needs of the coarse nitre dehydration process in the production of potassium nitrate.

The top of the cleaning agent barrel 202 is fixedly connected with a small water pump 203, which can generate sufficient suction to draw the cleaning agent from the cleaning agent barrel 202 and deliver it to the subsequent pipeline, realizing effective supply of the cleaning agent and providing power support for the cleaning work. The input end of the small water pump 203 is communicated with the front side bottom end of the cleaning agent barrel 202, which is conducive to fully sucking the cleaning agent at the bottom of the cleaning agent barrel 202, avoiding the residue of the cleaning agent and ensuring that sufficient cleaning liquid amount can be obtained for each cleaning. The output end of the small water pump 203 is communicated with a liquid supply pipe 204, which serves as a conveying channel for the cleaning agent and accurately sends the cleaning agent drawn out by the small water pump 203 to the parts inside the equipment that need to be cleaned, ensuring that the cleaning agent can reach each key position. The liquid supply pipe 204 penetrates the inside of the cylindrical barrel 1 and the conical barrel 3, so that the cleaning agent can penetrate deep into the inside of the equipment and directly act on the inner wall and other parts that may accumulate impurities, effectively removing the attached impurities and improving the comprehensiveness and effectiveness of the cleaning. The liquid supply pipe 204 is communicated with a plurality of liquid supply rings 205, which can uniformly distribute the cleaning agent inside the cylindrical barrel 1 and the conical barrel 3, ensuring that different positions can be fully cleaned and avoiding the occurrence of cleaning dead angles, thereby guaranteeing the overall cleaning effect of the equipment. The inside of each liquid supply ring 205 is equally communicated with a plurality of spray heads 206, which can spray the cleaning agent at a suitable angle and intensity, so that the cleaning agent can better impact and dissolve the impurities on the inner wall, enhance the cleaning effect, completely remove the dirt inside the equipment and maintain the good performance of the equipment.

[0043] Specifically, after the coarse nitrate dewatering hydrocyclone runs for a period of time, the interior needs to be cleaned to ensure its separation performance, at this time, the cleaning mechanism 2 starts to work, the carrier plate 201 serves as the support component of the entire cleaning mechanism 2, which is fixedly connected to the middle part of the rear side of the outer frame 12, providing a stable mounting basis for the cleaning agent barrel 202 and the small water pump 203, the cleaning agent barrel 202 is located at the top of the carrier plate 201 and is used to store the cleaning agent required for cleaning, the small water pump 203 is started, the input end of which is communicated with the front side bottom end of the cleaning agent barrel 202, and the cleaning agent is extracted from the cleaning agent barrel 202 by the suction force of the water pump, the extracted cleaning agent enters the liquid supply pipe 204 through the output end of the small water pump 203, the liquid supply pipe 204 penetrates the interior of the cylindrical barrel 1 and the conical barrel 3, and transports the cleaning agent to each position, the multiple liquid supply rings 205 communicated with the liquid supply pipe 204 are distributed in the areas requiring cleaning in the cylindrical barrel 1 and the conical barrel 3, finally, the cleaning agent is sprayed from the multiple spray heads 206 equidistantly communicated in the interior of the liquid supply ring 205, the spray heads 206 can spray at different angles, so as to uniformly spray the cleaning agent on the inner wall of the cylindrical barrel 1 and the conical barrel 3, effectively clean the impurities attached to the wall, prevent the impurities from accumulating and affecting the separation performance, thereby prolonging the service life of the equipment and ensuring the continuous and efficient operation of the equipment.

[0045] Specifically, the support legs 13 support the entire coarse nitrate dewatering hydrocyclone, keep it at a certain height, ensure the stability of the equipment during installation and operation, prevent the equipment from tilting or shifting due to its own weight or vibration during operation, and the non-slip pads 14 at the bottom of the support legs 13 are used to increase the friction between the support legs 13 and the ground, further improving the stability of the equipment. The maintenance valve 15 is convenient for the operator to operate the inside of the cylindrical cylinder 1 to check the condition of the internal parts of the equipment when the equipment needs to be repaired or maintained. The lifting lugs 16 are symmetrically installed on the top front and rear sides of the cylindrical cylinder 1, which is to facilitate the installation, disassembly and movement of the equipment. The lifting lugs 16 can be connected by ropes or hooks, and the coarse nitrate dewatering hydrocyclone can be lifted and accurately placed in the predetermined position by using a crane or other lifting equipment.

[0046] Referring to Figure 1 , the adjacent two support legs 13 at the front end are fixedly connected with a fixed plate 17, which provides a stable mounting position for the control button 18, ensures that the control button 18 will not loosen or shift due to external force during the operation of the equipment, ensures its normal work, and facilitates the operator to operate and control the related functions.

The outer frame 12 is fixedly connected with a plurality of diagonal braces 20 outside, and the plurality of diagonal braces 20 are fixedly connected in a cross shape. The diagonal braces 20 enhance the structural strength and stability of the outer frame 12, effectively disperse the external force such as liquid impact and vibration received by the equipment during operation, prevent the outer frame 12 from deforming or twisting, thereby ensuring that the internal components such as the cylindrical cylinder 1 and the conical cylinder 3 installed on the outer frame 12 maintain a relatively stable positional relationship, ensuring the reliability of the overall structure of the equipment, prolonging the service life of the equipment, and maintaining the continuous and stable progress of the coarse nitrate dewatering process;

[0048] Working principle: The coarse nitrate slurry first enters the cylindrical barrel 1 through the feed pipe 4, and the feed pipe 4 communicates with the cylindrical barrel 1 in a tangent direction, which makes the slurry have a certain tangential velocity when entering the cylindrical barrel 1, so that a rotating motion is rapidly formed in the cylindrical barrel 1. During the rotating process, the slurry generates a centrifugal force, and the heavier solid particles or the liquid with greater density begin to move towards the wall of the cylindrical barrel 1 under the action of the centrifugal force. As the slurry continues to flow downward into the conical barrel 3, the rotating motion of the slurry becomes more intense in the conical barrel 3, and the centrifugal force is further enhanced. In the conical barrel 3, the solid particles or the liquid with greater density are more strongly thrown to the wall and move downward along the wall in a spiral trajectory. At this time, the vortex inhibitor 7 located at the middle and lower end of the conical barrel 3 effectively changes the flow state of the slurry at the bottom. When the solid material and part of the liquid flow to the underflow outlet, the vortex inhibitor 7 prevents the formation of vortex and avoids air being sucked into the slurry. In this way, it ensures that the solid material can be stably and smoothly discharged through the threaded sand discharge nozzle 8 at the bottom of the conical barrel 3, while the clarified liquid or the fine particles carried in the liquid move to the central area of the cylindrical barrel 1 and rise under the action of the centrifugal force. At the top end of the inside of the cylindrical barrel 1, the flow guide cylinder 5 provides a stable channel for the rising liquid, which guides the clarified liquid or the fine particles to move upward smoothly and prevents them from mixing with the surrounding rotating slurry again or causing turbulence during the rising process. Finally, these clarified liquids or fine particles are discharged from the overflow outlet pipe 6 at the top of the cylindrical barrel 1. During the operation of the device, the threaded connection head 10 at the top of the sand collecting tank 9 cooperates with the threaded sand discharge nozzle 8 at the bottom of the conical barrel 3. When it is necessary to discharge the sand particles or other heavier impurities accumulated at the bottom, the operator can use the handles 11 fixedly connected at equal intervals on the outside of the sand collecting tank 9 to rotate the threaded connection head 10 out of the threaded sand discharge nozzle 8, thereby conveniently cleaning and collecting the sand particles and other impurities. The outer frame 12 fixedly connected outside the cylindrical barrel 1 and the conical barrel 3 plays a role in supporting and protecting the internal components;
