Description

Technical Field

[0001] This invention relates to the field of industrial salt production technology, specifically to a purification device for industrial salt production. Background Technology

[0002] Industrial salt is one of the basic raw materials of the chemical industry, mainly composed of sodium chloride and sodium nitrite, and is known as the "mother of the chemical industry." Major products in basic chemical industries, such as hydrochloric acid, caustic soda, soda ash, ammonium chloride, and chlorine, are primarily produced using industrial salt as a raw material. Furthermore, industrial salt has wide applications in organic synthesis, soap manufacturing, ceramics, glass production, daily chemical products, oil drilling, drilling fluids, completion fluids, petrochemical dehydration fluids, early-strength agents in the construction industry, coagulants in paint production, latex coagulants in the rubber industry, additives and waste paper deinking in the paper industry, inorganic chemical raw materials and sulfate removal agents in the chemical industry, as well as in water treatment, road snow removal, and refrigeration. However, impurity removal is a crucial step in the production of industrial salt. This is because industrial salt raw materials may contain various impurities, such as silt, organic matter, heavy metal ions, and moisture. These impurities not only affect the quality of the industrial salt but may also affect its subsequent application. Therefore, impurity removal equipment for industrial salt production has emerged, with the aim of removing impurities from industrial salt raw materials and improving the quality and purity of industrial salt.

[0003] Existing industrial salt production purification equipment typically separates the removal of particulate impurities from the removal of moisture. This approach not only increases costs but also reduces purification efficiency. Furthermore, the presence of moisture in the industrial salt can hinder the removal of particulate impurities. For instance, the moisture content can cause the industrial salt to clump together, and particulate impurities may be trapped within these clumps, making complete removal difficult and resulting in poor purification performance. Therefore, there is an urgent need to develop a purification equipment for industrial salt production to overcome the shortcomings of current practical applications. Summary of the Invention

The bottom of the flowing impurity removal hopper is also provided with a maintenance cover.

[0007] As a further aspect of the present invention: the impurity removal control component includes: A screen, located on the filtration and separation section, and respectively installed on the bottom and side of the flowing impurity removal hopper; The controller is fixedly installed on the flowing impurity removal hopper; And a heating plate, which is located on the evaporation and dehydration section and installed on the bottom of the flow impurity removal hopper.

[0008] As a further aspect of the present invention: the swing drive assembly includes: The support is fixedly connected to the fixed base; A drive motor, which is fixedly mounted on the support; And a transmission adjustment unit, which is connected to the flowing impurity removal hopper and the drive motor respectively.

[0009] As a further aspect of the present invention: the transmission adjustment unit includes: A rotating seat, which is fixedly installed on the flowing impurity removal hopper; A push-pull linkage, one end of which is rotatably connected to the rotating seat; And a crank adjusting rod, one end of which is rotatably connected to the other end of the push-pull connecting rod, and the other end of which is fixedly connected to the output end of the drive motor.

[0010] As a further aspect of the present invention, it also includes: a position control block, wherein the number of the position control blocks is two, and both of the position control blocks are fixedly installed on the flowing impurity removal hopper; A guide groove is formed on the position control block; And a crushing control component, which is connected to the position control block and the guide chute respectively.

[0011] As a further aspect of the present invention: the crushing control component includes: Adsorption device one and adsorption device two are respectively fixedly installed at both ends of the position control block and respectively set close to both ends of the guide groove. The positioning sliders are of two types, and the two positioning sliders are slidably installed in the two guide grooves respectively. The positioning sliders are also detachably connected to the adsorption device one and the adsorption device two respectively. And a crushing unit, which is connected to the two positioning sliders respectively and is located in the flow impurity removal hopper.

[0012] As a further aspect of the present invention: the crushing unit includes: A support link is provided, with its two ends fixedly connected to the two positioning sliders respectively, and a suspension plate is fixedly installed at both ends of the support link. A crushing blocking roller, the two ends of which are respectively fixedly connected to the two suspension support plates; And spikes, the number of which is multiple, and the multiple spikes are evenly distributed on the crushing blocking roller.

[0013] As a further aspect of the present invention, it also includes: a plurality of disturbance teeth, wherein the plurality of disturbance teeth are evenly distributed within the guide groove; And a vibration tooth, which is fixedly mounted on the support connecting rod and can be detachably connected to the disturbance tooth.

[0014] Compared with the prior art, the beneficial effects of the present invention are: When removing impurities from industrial salt, firstly, the oscillating drive assembly is activated, which rotates the flowing impurity removal hopper on the oscillating support. The flowing impurity removal hopper is positioned with the filtration and separation section high and the evaporation and dehydration section low. At this point, the machine is stopped, and the collected material tray after impurity removal is fixed in the receiving slot. Then, the industrial salt to be removed is released into the evaporation and dehydration section. After feeding is complete, the impurity removal control assembly is activated, which performs preliminary evaporation treatment on the industrial salt in the evaporation and dehydration section to remove the moisture contained in the industrial salt. However, since the industrial salt is in a piled-up state at this time, it is difficult to completely remove the moisture, and there may be uneven heating, which may affect the performance of the industrial salt. Reactivating the oscillating drive assembly causes the flowing impurity removal hopper to oscillate slightly. Under the obstruction of the V-shaped guide prism, the industrial salt on the evaporation and dehydration section flows within a certain space, allowing for thorough evaporation. After a period of evaporation, the oscillating drive assembly increases the amplitude of the oscillation of the flowing impurity removal hopper. At this time, the industrial salt in the evaporation and dehydration section is guided by the V-shaped guide prism and scattered towards the filtration and separation section. Under the influence of gravity, the industrial salt is dispersed and falls directly onto the side wall of the filtration and separation section, thus achieving thorough filtration and separating the industrial salt from other particulate impurities. The qualified industrial salt continues to fall into the receiving tray for further finer separation. As the flowing impurity removal hopper continues to rotate on the swing support, the industrial salt remaining in the filtration and separation section will flow back. During this process, the dispersed industrial salt continues to be thoroughly impurity removed as it flows through the filtration and separation section to the V-shaped guide prism. It is then dispersed again by the V-shaped guide prism to the evaporation and dehydration section for repeated evaporation and dehydration of larger particles or clumps of industrial salt. After this second dehydration, the industrial salt impacts the side of the filtration and separation section, further reducing the moisture content. Large particles or clumps of industrial salt are broken down and fall downwards, separating them from impurities. This process is repeated multiple times to achieve thorough impurity removal from the industrial salt and prevent the presence of large particles or clumps. Finally, the impurities are discharged from the outlet. The operation is simple and can achieve integrated removal of particulate impurities and moisture, which not only reduces production costs but also improves the efficiency of industrial salt impurity removal. In addition, it can break down larger particles or clumps in the industrial salt, preventing particulate impurities from adhering to the salt blocks, thereby further improving the impurity removal effect and providing convenience for workers.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1-8 The present invention provides a purification device for industrial salt production, including a fixed base 1, and further comprising: A swing bracket 2 is fixedly installed on the fixed base 1, and a flowable impurity removal hopper 3 is rotatably installed on the swing bracket 2. The flowable impurity removal hopper 3 is provided with a filtration separation section 4 and an evaporation dewatering section 5 on both sides respectively. The filtration and separation section 4 and the evaporation and dehydration section 5 are separated by a V-shaped guide prism 9, which is fixedly installed in the middle of the flow impurity removal hopper 3. And an industrial salt impurity removal mechanism, which is connected to the fixed base 1 and the flowing impurity removal hopper 3 respectively. The industrial salt impurity removal mechanism includes an impurity removal control component and an oscillating drive component. The impurity removal control component is connected to the flowing impurity removal hopper 3 and is located on the filtration separation section 4 and the evaporation dewatering section 5, respectively. The swing drive component is connected to the fixed base 1 and the flowing impurity removal hopper 3, respectively.

[0027] It also includes: a receiving slot 8, which is formed on the fixed base 1 and located below the filter separation section 4; The discharge port 6 is located on the flowing impurity removal hopper 3 and is connected to the evaporation and dehydration section 5. The bottom end of the flowing impurity removal hopper 3 is also provided with a maintenance cover 11.

[0028] When removing impurities from industrial salt, firstly, the oscillating drive assembly is activated, which rotates the flowing impurity removal hopper 3 on the oscillating support 2. The flowing impurity removal hopper 3 is positioned with the filtration separation section 4 at the high end and the evaporation and dehydration section 5 at the low end. At this point, the machine is stopped, and the collected material tray after impurity removal is fixed in the receiving slot 8. Then, the industrial salt that needs to be removed is released into the evaporation and dehydration section 5. After the feeding is completed, the impurity removal control assembly is activated, which can perform preliminary evaporation treatment on the industrial salt in the evaporation and dehydration section 5 to remove the moisture contained in the industrial salt. However, since the industrial salt is in an accumulated state at this time, it is difficult to remove the moisture completely, and there may be uneven heating, which may affect the performance of the industrial salt. At this point, restarting the oscillating drive assembly allows the flowing impurity removal hopper 3 to oscillate slightly. Under the obstruction of the V-shaped guide prism 9, the industrial salt on the evaporation and dehydration section 5 flows within a certain space, thus fully evaporating the industrial salt. After evaporation for a period of time, the oscillating drive assembly increases the amplitude of the reciprocating oscillation of the flowing impurity removal hopper 3. At this time, the industrial salt in the evaporation and dehydration section 5 is guided by the V-shaped guide prism 9 and scattered towards the filtration and separation section 4. Under the influence of gravity, the industrial salt is dispersed and falls directly onto the side wall of the filtration and separation section 4, thus fully filtering the industrial salt and separating it from other particulate impurities. The qualified industrial salt continues to fall into the receiving tray for further finer separation. As the flowing impurity removal hopper 3 continues to rotate on the swing support 2, the industrial salt still stagnating in the filtration separation section 4 will flow back. During the process of the industrial salt flowing in the filtration separation section 4 to the V-shaped guide prism 9, the industrial salt in a dispersed flow state can continue to be fully impurity removed until it is again scattered by the V-shaped guide prism 9 to the evaporation and dehydration section 5 for repeated evaporation and impurity removal of some large particles or clumps of industrial salt. When the industrial salt after being dehydrated again impacts the side of the filtration separation section 4, the impact will cause it to... Large particles or clumps of industrial salt with low moisture content are crushed and fall downwards, separating from impurities. This process is repeated multiple times to achieve thorough impurity removal from the industrial salt and prevent the presence of large particles or clumps. Finally, the impurities are discharged from the equipment through six discharge ports. The operation is simple and can achieve integrated removal of particulate impurities and moisture, which not only reduces production costs but also improves the efficiency of industrial salt impurity removal. In addition, it can crush larger particles or clumps in the industrial salt, preventing particulate impurities from adhering to the salt blocks, thereby further improving the impurity removal effect and providing convenience for workers.

[0029] In one embodiment of the present invention, please refer to Figures 1-8 The impurity removal control component includes: Screen 7, which is located on the filtration and separation section 4 and is respectively installed on the bottom and side of the flow impurity removal hopper 3; Controller 12, which is fixedly installed on the flowing impurity removal hopper 3; And a heating plate 10, which is located on the evaporation and dehydration section 5 and installed on the bottom of the flow impurity removal hopper 3.

[0030] The swing drive component includes: Support 14, which is fixedly connected to the fixed base 1; A drive motor 13 is fixedly mounted on the support 14; And a transmission adjustment unit, which is connected to the flowing impurity removal hopper 3 and the drive motor 13 respectively.

[0031] The transmission adjustment unit includes: Rotary seat 17, which is fixedly installed on the flowing impurity removal hopper 3; Push-pull linkage 16, one end of which is rotatably connected to the rotating seat 17; And a crank adjusting rod 15, one end of which is rotatably connected to the other end of the push-pull connecting rod 16, and the other end of which is fixedly connected to the output end of the drive motor 13.

[0032] In the initial stage of industrial salt impurity removal, the length of the crank adjusting rod 15 can be changed. The crank adjusting rod 15 can be in the form of a telescopic rod. After the drive motor 13 starts, it can drive the crank adjusting rod 15 to rotate. Through the pushing and pulling action of the push-pull connecting rod 16, the flow impurity removal hopper 3 can be slowly rotated on the swing support 2. This allows the industrial salt to fully remove the water contained in the industrial salt at the evaporation and dehydration section 5. As the industrial salt impurity removal continues, the crank adjusting rod 15 can be restored to its original length, and the height of the evaporation and dehydration section 5 can be increased. This allows the industrial salt at the evaporation and dehydration section 5 to flow to the filtration and separation section 4 and fall onto the screen 7 on the side of the filtration and separation section 4. Under the action of contact and impact, the industrial salt that meets the requirements can pass through the screen 7 and flow downward into the receiving tray.

[0033] In one embodiment of the present invention, please refer to Figures 1-8 It also includes: a position control block 18, wherein there are two position control blocks 18, and both position control blocks 18 are fixedly installed on the flow impurity removal hopper 3; Guide groove 25, the guide groove 25 is formed on the position control block 18; And a crushing control component, which is connected to the position control block 18 and the guide chute 25 respectively.

[0034] The crushing control component includes: Adsorption device 19 and adsorption device 20 are respectively fixedly installed at both ends of the position control block 18 and respectively set close to both ends of the guide groove 25. Positioning slider 26, there are two positioning sliders 26, the two positioning sliders 26 are slidably installed in the two guide grooves 25 respectively, and the positioning sliders 26 are also detachably connected to the adsorption device 19 and the adsorption device 20 respectively. And a crushing unit, which is connected to the two positioning sliders 26 respectively and is located in the flow impurity removal hopper 3.

[0035] The crushing unit includes: The support link 23 is fixedly connected to the two positioning sliders 26 at both ends, and a suspension plate 24 is fixedly installed at both ends of the support link 23. The crushing blocking roller 21 is fixedly connected to the two suspension support plates 24 at both ends. And spikes 22, there are multiple spikes 22, and the multiple spikes 22 are evenly distributed on the crushing blocking roller 21.

[0036] It also includes: a disturbance tooth 28, wherein there are multiple disturbance teeth 28, and the multiple disturbance teeth 28 are evenly distributed in the guide groove 25; And a vibration tooth 27, which is fixedly installed on the support connecting rod 23 and is detachably connected to the disturbance tooth 28.

[0037] As the industrial salt flows from the evaporation and dehydration section 5 to the filtration and separation section 4, the position of the evaporation and dehydration section 5 gradually increases, while the position of the filtration and separation section 4 gradually decreases. Firstly, under the adsorption action of the second adsorption device 20, the positioning slider 26 will stop at the end of the guide chute 25. Both the first adsorption device 19 and the second adsorption device 20 can be in the form of electromagnets. When the positioning slider 26 is at the lower end of the guide chute 25, the crushing and blocking roller 21 is relatively close to the heating plate 10. At this time, under the blocking action of the crushing and blocking roller 21, only smaller particles of industrial salt and impurities will pass through the crushing and blocking section. The blocking roller 21, along with the V-shaped guide prism 9, disperses the industrial salt towards the screen 7, thus ensuring thorough removal of impurities. This prevents the qualified industrial salt from being completely discharged from the screen 7 due to the obstruction of larger particles or clumps of industrial salt. Clumps of industrial salt are blocked by the breaking blocking roller 21 onto the heating plate 10 (because clumps of industrial salt remain on the heating plate 10 for a longer time, the removal of moisture is more thorough). When the evaporation and dehydration section 5 is about to reach its highest point, the adsorption device 19 is powered on while the adsorption device 20 is powered off. Under the action of gravity, the positioning slider 26 will move towards the guide chute 25. The internal sliding mechanism slides to the guide chute 25 near one end of the adsorption device 19. When the positioning slider 26 moves the crushing blocking roller 21 via the suspension support plate 24, the distance between the crushing blocking roller 21 and the heating plate 10 increases, allowing agglomerated or large-particle industrial salt to flow smoothly downwards and collide with the screen 7 to produce crushing and filtration. At this time, the position of the crushing blocking roller 21 is flush with the top of the V-shaped guide prism 9. When the industrial salt flows back from the filtration separation section 4 to the evaporation and dehydration section 5, it falls onto the crushing blocking roller 21 and contacts multiple spikes 22 as it is scattered by the V-shaped guide prism 9. The system can fully break up clumps of industrial salt, and after breaking them up, it can fully remove water at the evaporation and dehydration section 5. When the filtration and separation section 4 is about to reach its highest point, the breaking blocking roller 21 and the positioning slider 26 return to their original positions. This reciprocating motion can achieve the purpose of fully removing impurities. In addition, through the coordinated operation of the vibration teeth 27 and the disturbance teeth 28, when the positioning slider 26 slides in the guide groove 25, the vibration teeth 27 and the disturbance teeth 28 collide and generate vibration, which shakes off the industrial salt that is adhered to the breaking blocking roller 21 or stuck between adjacent spikes 22, thus avoiding waste of raw materials.
