Description

Technical Field

[0001] This utility model relates to the field of drying production line technology, specifically a potassium nitrate drying production line. Background Technology

[0002] As is well known, a potassium nitrate drying production line is a combination of specialized production equipment used to remove excess moisture from potassium nitrate crystals to achieve a qualified moisture content. The core objective is to ensure stable product quality and meet subsequent storage and transportation requirements. Generally, materials are processed using a dryer.

[0003] Existing potassium nitrate drying production lines have significant limitations in actual operation: the feed inlet of its feeding component is in constant contact with the wet potassium nitrate crystals to be dried. The wet material easily adheres to the inner wall of the inlet due to moisture, and over time, the adhered material gradually clumps up, which may not only narrow the feeding channel and affect the material conveying rate, but may also mix into the subsequent drying process, causing fluctuations in product purity. Therefore, the inner wall of the feed inlet must be cleaned regularly. However, under the existing structure, if the cleaning requirement is triggered during the material feeding operation, the feeding process must be completely stopped. The equipment can only be restarted after the staff disassembles the component and cleans the inner wall. The production line cannot operate continuously during the entire cleaning period, which directly leads to a significant reduction in overall production efficiency and makes it difficult to meet the requirements of continuous production. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a potassium nitrate drying production line.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a potassium nitrate drying production line, comprising a machine body, a support base, a feeding mechanism, a connecting mechanism, and a cleaning mechanism. The support base is located at the bottom of the machine body, and several support bases are provided. The feeding mechanism includes a sealing plate and a feeding assembly. The sealing plate contacts the top of the machine body, and the feeding assembly is located on the sealing plate. The connecting mechanism includes a first sliding groove, a first sliding block, an electric push rod, a connecting block, and a locking block. The first sliding groove is located at the top of the machine body. One end of the first sliding block extends into the first sliding groove, and the other end of the first sliding block is connected to one end of the electric push rod. The other end of the electric push rod is connected to the connecting block... One end of the connecting block is connected to the connecting block, and the other end of the connecting block is connected to the sealing plate. One end of the locking block is connected to the connecting block, and the other end of the locking block extends into the interior of the machine body. The cleaning mechanism includes a second slide groove, a second slider, a brush plate, a push handle, a long block, and an electromagnet. The second slide groove is opened on the top of the machine body. One end of the second slider extends into the second slide groove, and the other end of the second slider is connected to the brush plate. The push handle is set on one side of the brush plate. One end of the long block is connected to the brush plate, and the other end of the long block is connected to one end of the electromagnet. The other end of the electromagnet attracts the sealing plate. A controller is provided on the front of the machine body, and the controller is electrically connected to the machine body.

[0008] To facilitate operation of the equipment, the present invention is improved in that the controller is electrically connected to the electric push rod and the controller is electrically connected to the electromagnet.

[0011] To improve the connection effect, the present invention is improved by welding the support base to the body.

[0012] To improve the strength of the support, this utility model is improved by making the support made of alloy steel.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a potassium nitrate drying production line, which has the following beneficial effects:

[0015] This potassium nitrate drying production line excels in ease of operation and production continuity. By centrally controlling electric push rods and electromagnets with a controller, it can quickly reposition the sealing plate, exposing a temporary feed inlet at the top of the machine. This solves the problem of traditional production lines requiring shutdowns to clean materials adhering to the inner walls of the feeding components. During cleaning, materials can still be replenished through the temporary opening, effectively preventing production interruptions and significantly improving work efficiency. Regarding structural stability, symmetrically distributed alloy steel support seats are welded and fixed to the machine body, combined with a T-shaped adaptive sliding block structure. This ensures the overall equipment is stable and free from displacement and shaking, while also guaranteeing precise and smooth operations such as sealing plate repositioning and cleaning, reducing component friction wear. Simultaneously, the machine body adopts a mature fluidized bed structure, lowering the operational and maintenance threshold and comprehensively meeting the high-efficiency, stable, and low-loss requirements of potassium nitrate drying production.

[0023] Working principle

[0024] Equipment initialization operation: First, move the entire potassium nitrate drying production line to the designated production area, ensuring that the equipment is placed horizontally and without any obstructions around it. Use the support base 2 at the bottom of the machine body 1 to achieve stable support for the equipment and avoid displacement caused by vibration during operation. Then connect the equipment power cord to the external mains power to complete the power supply circuit construction and provide power support for the subsequent operation of each component.

[0025] Main equipment description: The core drying device (body 1) of this production line adopts the mature fluidized bed dryer structure on the market. Its internal components include conventional components such as hot air distribution plate, fluidized bed chamber, and discharge valve. The specific structural composition and basic working principle of hot air convection drying are common knowledge to those in this technical field and will not be elaborated here.

[0026] Conventional drying process: After starting the equipment, the wet potassium nitrate crystals to be dried are uniformly fed into the machine body 1 through the feeding component 5 installed on the sealing plate 4. After the material enters the fluidized bed chamber, it comes into full contact with the hot air delivered by the heating system to complete heat exchange and moisture evaporation, and finally forms a finished potassium nitrate product that meets the moisture content requirements. The specific drying parameters (such as hot air temperature and wind speed) at this stage can be referred to the conventional operation specifications of the fluidized bed dryer, which will not be described in detail here.

[0027] Feed component cleaning process (core optimization step):

[0028] Cleaning trigger condition: When the inner wall of the feeding component 5 becomes obviously sticky and clumpy due to prolonged contact with wet materials, affecting the material conveying efficiency, the normal feeding of the feeding component 5 needs to be suspended and a special cleaning process needs to be initiated.

[0029] Plate relocation operation: such as Figure 1 As shown, the operator first cuts off the power supply to the electromagnet 18 at the end of the long block 17, causing the electromagnet 18 to lose its magnetism and release the adsorption and fixation of the martensitic stainless steel sealing plate 4. Then, the electric push rods 9 on both sides are started simultaneously. The electric push rods 9 extend and drive the connecting block 10 and the sealing plate 4 fixed thereto to rise vertically until the locking block 11 on one side of the connecting block 10 is completely disengaged from the locking groove at the top of the machine body 1, releasing the limiting constraint of the sealing plate 4. Then, the sealing plate 4 is pushed so that the first slider 8 connected at the bottom slides horizontally along the T-shaped first sliding groove 7 at the top of the machine body 1, completely exposing the temporary feed port at the top of the machine body 1.

[0030] Temporary material supply guarantee: After the temporary feed port is exposed, potassium nitrate wet crystals can be manually added to the inside of the machine body 1 through the opening to ensure the continuous operation of the drying host and avoid the shutdown of the entire production line due to cleaning the feed component 5, thus ensuring production continuity.

[0031] Component cleaning and material recycling: After the temporary feeding task is completed, the staff uses an external cleaning brush (it is recommended to use wear-resistant nylon material to avoid scratching the inner wall of the feeding component) to thoroughly clean the inner wall of the feeding component 5, remove the sticky wet material clumps, and the potassium nitrate material that falls during the cleaning process will naturally fall into the flat area on the top of the machine body 1. At this time, the staff holds the push handle 16 of the cleaning mechanism 12 and pushes the brush plate 15, so that the T-shaped second slider 14 at the bottom of the brush plate 15 slides smoothly along the second slide groove 13, and the brush bristles of the brush plate 15 clean the scattered material on the top of the machine body 1.

[0032] Equipment reset and subsequent maintenance: After cleaning, restore the equipment to its original state in the reverse order of disassembly. Figure 1The initial state shown is described. The specific steps of this reset operation are routine procedures for those skilled in the art and will not be described in detail here. In addition, the first slide 7, the first slider 8, the second slide 13 and the second slider 14 mentioned in this article all adopt a T-shaped structure design. In order to prevent dust accumulation inside the slide from affecting the sliding of the slider, it is recommended that the staff regularly use an external vacuum cleaner (equipped with a thin nozzle) to clean the inside of the slide. The cleaning cycle can be adjusted according to the dust concentration in the production environment (usually recommended 1-2 times per week).

[0033] To further improve the ease of operation and control precision of the equipment, this utility model makes targeted improvements: the controller 19 located on the front of the machine body 1 is electrically connected to the electric push rod 9 and the electromagnet 18 respectively, forming a centralized control circuit. With this design, the operator does not need to manually operate the extension and retraction of the electric push rod 9 or the attraction / desorption of the electromagnet 18. They only need to trigger the corresponding command on the controller 19 to accurately control the electric push rod 9 to drive the sealing plate 4 to rise and fall, and simultaneously realize the magnetic fixation and release of the electromagnet 18 on the sealing plate 4. This greatly simplifies the operation process of sealing plate displacement, equipment reset, etc., reduces human intervention error, and avoids the safety hazards that may be caused by manual operation, ensuring that the entire control process is efficient, stable and easy to control.

[0034] To further improve the overall stability of the potassium nitrate drying production line and prevent tilting, vibration, or displacement of the machine body 1 due to uneven stress, this utility model makes targeted improvements: several support seats 2 are symmetrically distributed and installed with the center of the bottom of the machine body 1 as the axis of symmetry. This design allows the support seats 2 to evenly bear the weight of the machine body 1 and the internal materials, effectively dispersing the load generated during equipment operation (such as vibration during the operation of the drying host and impact force during material conveying), and preventing deformation or damage to local support seats 2 due to excessive stress. At the same time, the symmetrical layout ensures that the machine body 1 always remains horizontal, providing a stable foundation for precise feeding of the feeding component 5 and smooth sliding of the cleaning mechanism 12, avoiding the impact of equipment tilt on the collaborative working efficiency of each component, and ensuring the long-term stable operation of the production line from a structural perspective.

[0035] To further improve the stability and operational precision of component sliding during equipment operation and avoid jamming or displacement due to insufficient compatibility between the slide groove and the slider, this utility model makes targeted improvements: the first slide groove 7 at the top of the machine body 1 and the matching first slider 8 are designed to be perfectly matched in size and shape. At the same time, the second slide groove 13 and the corresponding second slider 14 are highly compatible. This design ensures that the first slider 8 slides horizontally in the first slide groove 7 without gaps or shaking, stably driving the sealing plate 4 to move; it also allows the second slider 14 to be precisely guided when moving along the second slide groove 13, preventing the brush plate 15 from shifting and affecting the material cleaning effect. In addition, the compatible structure can also reduce frictional wear between components, extend the service life of the slide groove and the slider, provide stable support for key operations such as sealing plate displacement and brush plate cleaning, and ensure the smooth operation of all links in the production line.

[0036] To further enhance the connection stability between the support base 2 and the machine body 1, and to prevent loosening or displacement due to vibration and load changes during equipment operation, this utility model makes targeted improvements: A welding process is used to achieve a fixed connection between the support base 2 and the bottom of the machine body 1. Compared to bolt connections, welding allows the support base 2 and the machine body 1 to form an integrated structure, completely eliminating connection gaps, significantly improving overall load-bearing strength, and ensuring that the support base 2 can stably support the weight of the machine body 1 and the internal materials. Simultaneously, the welded connection can effectively resist the impact and vibration transmission generated during equipment operation (such as the operation of the drying host and material conveying), preventing problems such as offset or detachment of the support base 2. This provides reliable structural support for the long-term stable operation of the production line, ensuring the safety and stability of the overall equipment operation from the connection perspective.

[0037] To further enhance the load-bearing strength and durability of the support base 2 and ensure its long-term stable support of the weight of the machine body 1 and internal materials, this utility model makes targeted improvements: alloy steel is selected as the material for the support base 2. Compared with ordinary carbon steel, alloy steel, with its special metallographic structure formed by the addition of alloying elements (such as chromium and manganese), has higher tensile strength, compressive strength, and deformation resistance. It can effectively resist the load generated during equipment operation (such as vibration generated by the operation of the drying host and impact force when materials are fed), and prevent the support base 2 from bending, breaking, or other damage. At the same time, alloy steel has better wear resistance and corrosion resistance, which can reduce the erosion of the support base 2 by dust and moisture in the production environment, extend its service life, and provide reliable protection for the overall structural stability of the production line from the material level, ensuring the long-term safe operation of the equipment.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
