Description

Technical Field

[0001] This utility model belongs to the field of potassium chloride production technology, and specifically relates to a device for adding anti-caking agents before an electrostatic atomization coupled fluidized bed in potassium chloride production. Background Technology

[0002] In potassium chloride production, the addition of anti-caking agents is an important step in ensuring that the salt product maintains good flowability during storage and transportation.

[0003] Currently, common methods for adding anti-caking agents mainly include traditional spraying and dry addition. Traditional spraying has many drawbacks, such as uneven spraying, leading to uneven distribution of the anti-caking agent in the salt, which in turn causes salt particle agglomeration, forming a large amount of residue on the screen. This not only wastes the anti-caking agent but also reduces product quality and yield. Dry addition, on the other hand, faces problems such as insufficient mixing, dust generation, and difficulty in controlling the addition precision, affecting the production environment and the health of operators, while also making it difficult to guarantee the stability of product quality. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a device for adding anti-caking agents before an electrostatic atomization coupled fluidized bed in potassium chloride production. This device not only sprays the anti-caking agent evenly onto the surface of the salt particles, but also ensures that the salt particles are fully loosened during the conveying process, further improving the uniform distribution effect of the anti-caking agent addition.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a device for adding anti-caking agent before electrostatic atomization coupled fluidized bed in potassium chloride production, including a vibrating feeder and an electrostatic sprayer. The vibrating feeder includes a feeder body, on which a vibrating motor is installed. The feeder body is connected to a support frame through a composite vibration reduction system. An opening is also provided on the feeder body.

[0006] The electrostatic sprayer includes a multi-hole nozzle corresponding to the opening.

[0007] As a further improvement of this utility model, there are two support frames, which are respectively set on both sides of the feeder body.

[0008] As a further improvement of this utility model, the composite vibration reduction system includes a vibration isolation device connected to the feeder body, and the vibration isolation device is connected to the support frame through a vibration isolation spring.

[0009] As a further improvement of this utility model, a feeding trough is provided on one side of the feeder body, and a discharge port is provided on the other side of the feeder body, with the opening located close to the feeding trough.

[0010] As a further improvement of this utility model, the electrostatic sprayer also includes a storage tank for storing an anti-caking agent solution. An electrostatic emitter is installed on the storage tank, and a metering pump is also installed in the storage tank. The metering pump is connected to the atomizing nozzle motor through a liquid guide pipe, and the multi-hole nozzle is connected to the atomizing nozzle motor.

[0011] As a further improvement of this utility model, the electrostatic sprayer also includes an energy storage device, which supplies power to the electrostatic generator and the metering pump, and the energy storage device is equipped with a charging plug.

[0012] As a further improvement of this utility model, a display is also provided on the liquid storage tank, and the display is electrically connected to the voltage of the metering pump, the electrostatic generator, and the vibration motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Firstly, a combination of electrostatic spraying and a vibrating feeder is employed. Electrostatic spraying technology uses an electrostatic field to ensure that anti-caking agent droplets adhere evenly to the surface of salt particles, avoiding the unevenness of traditional spraying. The vibrating feeder ensures that the salt particles are fully loosened during transport, further improving the uniform distribution of the anti-caking agent. This combined approach not only achieves uniform addition of the anti-caking agent, effectively reducing agglomeration and oversize material, thus improving product quality and stability, but also reduces dust pollution, improves the production environment, simplifies the process, and increases production efficiency, resulting in significant economic and social benefits.

[0015] Secondly, electrostatic atomization enables precise coating. Compared to the salt particle agglomeration problem caused by uneven dispersion of anti-caking agent droplets in traditional pneumatic or mechanical spraying processes, this solution uses high-voltage electrostatic atomization to depolymerize the anti-caking agent solution into charged microdroplets, which are then directionally adsorbed onto the surface of salt particles under the action of Coulomb force, forming a monolayer molecular-level coating. This reduces the proportion of oversize material and strictly controls the anti-caking agent content within the range of ≤10mg / kg specified in GB 26878-2011, completely eliminating the rework and recycling process.

[0016] Third, vibration feeding enhances mixing uniformity: High-frequency micro-vibration replaces conventional belt conveyor, keeping salt particles in a continuous tumbling state, increasing the penetration depth of anti-caking agent droplets, and reducing particle agglomeration rate. Under the same anti-caking effect, the amount of anti-caking agent required is significantly reduced. Attached Figure Description

[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] like Figure 1 As shown, a device for adding an anti-caking agent before an electrostatic atomization coupled fluidized bed in potassium chloride production includes a vibrating feeder and an electrostatic sprayer. The vibrating feeder includes a feeder body 2, which is inclined and equipped with a vibrating motor 1. The feeder body 2 is connected to a support frame 18 via a composite vibration damping system. The feeder body 2 also has an opening 5. The electrostatic sprayer includes a multi-hole nozzle 9 corresponding to the opening 5. The support frame 18 is a steel support frame.

[0023] A feeding trough 11 is provided on one side of the feeder body 2, and a discharge port 12 is provided on the other side of the feeder body 2. The opening 5 is located near the feeding trough 11. The surface of the feeding trough 11 is made of non-stick 304 stainless steel. The opening 5 is located at the top of the feeder body 2 and is rectangular with dimensions of 150×80mm. It has an adjustable guide plate built in to position the spray area. The inclination angle of the feeding trough 11 is 10°.

[0024] like Figure 1 As shown, there are two support frames 18, which are respectively set on both sides of the feeder body 2.

[0025] like Figure 1 As shown, the composite vibration reduction system includes a vibration isolation device 3 connected to the feeder body 2, and the vibration isolation device 3 is connected to the support frame 18 through a vibration isolation spring.

[0026] like Figure 2As shown, the electrostatic sprayer also includes a storage tank 19 for storing the anti-caking agent solution. An electrostatic emitter is installed on the storage tank 19. A metering pump 17 is also installed in the storage tank 19, connected to an atomizing nozzle motor 8 via a liquid guide pipe 7. A multi-hole nozzle 9 is also connected to the atomizing nozzle motor 8. The storage tank 19 has a volume of 20L and is made of 316L stainless steel. A magnetic stirring device is also installed in the storage tank 19, with a stirring speed of 50-200 rpm to ensure uniform and stable solution. The metering pump 17 is a plunger pump with a flow accuracy of ±0.5%. The liquid guide pipe 7 is a PTFE hose.

[0027] like Figure 2 As shown, the electrostatic sprayer also includes a power storage device 15, which supplies power to the electrostatic generator 16 and the metering pump 17. A charging plug 10 is provided on the power storage device 15. The power storage device 15 is a 48V / 100Ah lithium battery pack; the charging plug 10 supports IP67 protection fast charging.

[0028] The lower end of the liquid storage tank 19 forms an installation cavity 14 through the partition 13. The metering pump 17 is installed on the partition 13, and the energy storage device 15 and the electrostatic generator 16 are installed in the installation cavity 14.

[0029] Workers can first activate the magnetic stirrer to agitate the anti-caking agent solution in the storage tank 19, ensuring a uniform and stable solution. Then, they can activate the electrostatic generator 16 to charge the solution with static electricity. Afterward, the metering pump 17 can be started, transporting the charged solution from the storage tank 19 to the atomizing nozzle motor 8 via the liquid guide pipe 7. The atomizing nozzle motor 8 drives the multi-hole nozzle 9 to atomize the anti-caking agent solution into charged droplets of 10-30 μm. Under the influence of Coulomb force, the charged droplets enter the equipment through the opening 5 at the top of the feeder body 2. The opening 5 is a 150×80 mm rectangle with an adjustable guide plate to position the spray area.

[0030] Salt particles enter the feeder body 2 through a filter tank. The feed tank 11 has an inclination angle of 10° to ensure continuous tumbling of the particles. The salt particles move forward in the feeder body 2 at a conveying speed of 0.5–2.0 m / s. During the vibration conveying process, the salt particles carry a surface potential of +1kV–+3kV due to friction. Under the action of Coulomb force, charged anti-caking agent solution droplets enter the feeder body 2 through opening 55 and are directionally adsorbed onto the salt particles. Therefore, the charged droplets can be directionally adsorbed on the surface to form a single-layer molecular-level coating, thereby improving the penetration depth and coverage of the anti-caking agent. The discharge port 12 of the feeder body 2 outputs the processed salt particles for subsequent production processes.

[0031] Due to the combination of electrostatic atomization and vibratory feeding, the amount of anti-caking agent used is reduced by about 35%, the proportion of oversize material is less than 1%, the product quality and stability are significantly improved, and dust pollution is reduced, thus improving the production environment.

[0032] like Figure 2 As shown, a display 6 is also installed on the liquid storage tank 19. The display 6 is electrically connected to the voltage of the metering pump 17, the electrostatic generator 16, and the vibration motor 1. The user can adjust the pump speed of the metering pump 17, the voltage of the electrostatic generator 16, and the vibration parameters of the vibration motor 1 in real time through the display 6. When the machine is stopped, it will automatically perform pure water rinsing and ultrasonic cleaning to ensure zero crystallization and clogging of the nozzle.

[0033] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
