Description

Technical Field

[0001] This utility model relates to the field of salt addition technology, and more specifically, to a salt product powder dissolution and addition device. Background Technology

[0002] Salt powder dissolving and adding equipment has wide applications in chemical, food processing, water treatment, and metallurgical industries. Its core function is to efficiently and uniformly dissolve solid salt products in liquids to prepare solutions of specific concentrations for subsequent processing. In these industries, the precision of salt solution addition and the quality of dissolution directly affect the quality of the final product, production efficiency, and cost control. For example, in water treatment, salt solutions are used for the regeneration of ion exchange resins; in the food industry, salt solutions are used as flavorings or preservatives; and in chemical production, salt solutions serve as raw materials or catalyst carriers for many reactions. Therefore, developing a highly automated salt powder dissolving and adding equipment with excellent dissolution effects and long-term stable operation is of great significance for improving the continuity and reliability of industrial production.

[0003] Currently, the common industrial methods for dissolving and adding powdered salt products mainly rely on simple mechanical devices or semi-automated equipment. A typical design includes a storage silo for holding the salt powder, a dissolving tank for mixing the salt and liquid, and a conveying mechanism to transfer the salt from the storage silo to the dissolving tank. The dissolving tank is usually equipped with an agitator, using a motor-driven paddle to promote mixing of the salt and liquid. In addition, some devices also have temporary storage tanks to store the dissolved solution for on-demand supply to downstream processes. While these existing technologies have achieved a degree of automation in salt addition and dissolution, they have revealed a series of problems in actual operation. First, salt products, especially powdered salt, are highly susceptible to moisture absorption and agglomeration during storage due to environmental humidity and temperature, forming hard lumps. Agglomeration not only clogs conveying channels, causing interruptions or reduced efficiency, but also makes it difficult to disperse the salt in the dissolving tank, prolonging dissolution time, and even overloading the agitator and damaging the motor. Second, existing anti-agglomeration measures are often passive, such as simply installing a simple anti-agglomeration device in the storage silo or periodic manual tapping; these methods have limited effectiveness and cannot sustainably prevent agglomeration. More specifically, the root cause of salt product clumping lies in its hygroscopic nature. When the ambient humidity is high, the surface of the salt powder absorbs moisture, forming a saturated solution film. Subsequently, under temperature fluctuations or pressure, the salt crystals recrystallize and bond together. In existing technologies, some improvements attempt to reduce humidity in storage silos through heating or ventilation. However, heating may accelerate the deliquescence of salt, while ordinary ventilation cannot effectively control humidity and may even introduce more humid air.

[0004] To address the aforementioned issues, the industry has proposed several partial solutions. For example, installing mechanical agitators or vibrators within storage silos to break up agglomerates is an option, but these devices are noisy, energy-intensive, and prone to wear and tear with prolonged use. Another approach is to use anti-caking additives, but this may introduce impurities in food or high-purity applications and is therefore unacceptable. In the dissolving stage, high-speed shear stirring or ultrasonic dissolving technologies have been employed, but these methods involve complex equipment, high costs, and difficult maintenance. Therefore, current technology lacks an integrated solution that can effectively prevent salt agglomeration throughout the entire process from storage and transportation to dissolution, while ensuring dissolution efficiency and quality.

[0005] Chinese utility model patent CN223312004U describes an automatic salting and stirring device for the water treatment industry. It includes a salt dissolving tank, a water supply pipe connected to the top of the tank, a salt supply rack connected to the other side of the tank, a salt bucket installed on one side of the rack near the bottom, a drain pipe connected to the bottom of the tank, and a stirring assembly installed inside the tank. The salt bucket can store materials and is continuously fed by a drive mechanism. The stirring assembly inside the tank can agitate and mix the salt and water, solving the problem of clogging that easily occurs when adding salt in existing equipment. However, it does not solve the problem of salt clumping due to moisture in the salt bucket. Utility Model Content

[0026] This utility model proposes a salt product powder dissolving and adding device.

[0027] The following embodiments will provide a detailed description of the salt product powder dissolving and adding equipment of this application.

[0028] Example 1: like Figure 1 , 2 As shown in the figure, this embodiment proposes a salt product powder dissolving and adding device, characterized in that it includes: a storage section 1 for storing salt, with an opening at its upper end; a dissolving section 2, including a dissolving tank 21 and a stirring device 22 disposed therein for promoting the dissolution of liquid and salt in the dissolving tank 21; a conveying device 3 connecting the storage section 1 and the dissolving tank 21 for conveying salt from the storage section 1 to the dissolving tank 21; a temporary storage section 4 connected to the dissolving tank 21 for storing the solution after salt addition; and an anti-coagulation device 5 disposed on the storage section 1 for preventing salt from clumping in the storage section 1.

[0029] The storage section 1 is a hopper with a feeding port at the top for storing salt powder; the dissolving section 2 includes a dissolving tank 21, in which a motor-driven stirring rod 221 is installed to promote the dissolution of salt and liquid; the conveying device 3 is a screw conveyor that connects the storage section 1 and the dissolving tank 21 to continuously convey the salt powder into the dissolving tank 21; the temporary storage section 4 is a temporary storage tank connected to the bottom of the dissolving tank 21 for storing the dissolved solution; the anti-coagulation device 5 introduces cold and dry air into the storage section 1 while stirring the salt in the storage section 1 to prevent the salt from deliquescing, solidifying, or clumping.

[0030] Example 2: This embodiment is a further improvement based on Embodiment 1.

[0031] like Figure 3As shown, in this embodiment, the anti-coagulation device 5 includes: a lifting device 51, used to lift a portion of the salt at the bottom of the storage section 1 to the top and let it fall along the outer wall of the storage section 1; and a cooling and dehumidification device 52, used to reduce the temperature and humidity inside the storage section 1.

[0032] The anti-condensation device 5 includes a lifting device 51 and a cooling and dehumidification device 52. The lifting device 51 is implemented by a screw conveyor installed in the storage section 1. The conveyor transports the salt powder from the bottom upwards and when it reaches the highest point, the salt powder naturally falls to the surroundings and is evenly distributed back to the material pile along the storage section 1, realizing circulation and turning. The cooling and dehumidification device 52 is a high-pressure airflow compressed by a compressor 522 installed at the top of the storage section 1 and cooled and dehumidified by a dry cooler 523. Together, they reduce the temperature and humidity of the air inside the storage section 1, preventing the salt powder from absorbing moisture and clumping from the source.

[0033] Example 3: This embodiment is a further improvement based on any of the above embodiments.

[0034] like Figure 3 As shown, in this embodiment, the lifting device 51 includes: a cover plate 511, which covers the opening and has several through holes; a lifting rod 512, which is a spiral shaft, one end of which extends into the cavity inside the storage section 1, and the other end passes through the cover plate 511 and is rotatably mounted on the cover plate 511; and a lifting motor 513, which is mounted on the cover plate 511 and whose output shaft is connected to one end of the lifting rod 512 that passes through the cover plate 511, and can drive the lifting rod 512 to rotate.

[0035] The cover plate 511 tightly covers the opening of the storage section 1, preventing salt from spilling out from the upper opening. The through hole on the cover plate 511 also serves as a cooling and dehumidifying device 52 and the storage section 1. The lifting rod 512 is a vertically arranged spiral shaft, with its lower end extending into the inner cavity of the storage section 1 and its upper end passing through the cover plate 511 and rotatably mounted on the cover via a bearing. The lifting motor 513 is fixedly installed on the upper surface of the cover plate 511, and its output shaft is directly connected to the upper end of the lifting rod 512 passing through the cover plate 511 via a coupling, thereby driving the spiral shaft to rotate and lift the salt powder.

[0036] Example 4: This embodiment is a further improvement based on any of the above embodiments.

[0037] like Figure 3 As shown, in this embodiment, the cooling and dehumidification device 52 includes: a sealing cover 521, which covers the top of the cover plate 511; a compressor 522, which outputs high-pressure airflow; and a dry cooler 523, whose input end is connected to the output end of the compressor 522, and whose output end is connected to the cavity inside the sealing cover 521.

[0038] A sealing cover 521 is inverted and covers the cover plate 511 of the lifting device 51 to form a sealed space. An air compressor 522 is located externally to generate and output high-pressure airflow. The input end of a refrigerated dry air conditioner 523 is connected to the output end of the compressor 522 via a pipe, and its output end extends to the internal cavity of the sealing cover 521 via another pipe, thereby continuously introducing the cooled and dehumidified dry air into the sealing cover 521, and finally entering the storage section 1 through the through hole on the cover plate 511, reducing the temperature and humidity in the storage section 1. The dry air conditioner 523 includes a heat exchanger, an evaporator, and a gas-liquid separator. The high-pressure humid and hot airflow output from the compressor 522 first passes through the heat exchanger for preliminary cooling. The cooled airflow is further cooled by the evaporator into low-temperature, low-humidity airflow and condensate. After passing through the gas-liquid separator, only the low-temperature, low-humidity airflow enters the sealing cover 521.

[0039] Example 5: This embodiment is a further improvement based on any of the above embodiments.

[0040] like Figure 3 As shown, in this embodiment, the stirring device 22 includes: a stirring rod 221, one end of which is provided with a plurality of blades, and the other end passes through the upper end of the dissolving tank 21 and is rotatably disposed on the dissolving tank 21; a stirring motor 222, which is disposed on the dissolving tank 21, and the output shaft of the stirring motor 222 is connected to the stirring rod 221, which can drive the stirring rod 221 to rotate.

[0041] The stirring rod 221 is vertically arranged, with its lower end extending into the dissolving tank 21 and equipped with several inclined blades. Its upper end passes through the top cover of the dissolving tank 21 and is rotatably mounted on the tank body through a bearing seal. A stirring motor 222 is fixedly installed above the top cover of the dissolving tank 21 by a bracket. Its output shaft is directly connected to the upper end of the stirring rod 221 through a coupling, thereby driving the stirring rod 221 and blades to rotate in the tank to achieve the stirring function. The rotation of the blades causes the solution to form a vortex, accelerating the dissolution of salt.

[0042] Example 6: This embodiment is a further improvement based on any of the above embodiments.

[0043] like Figure 3As shown, in this embodiment, the conveying device 3 includes: a conveying channel 31, the two ends of which are respectively connected to the inner cavity of the storage section 1 and the inner cavity of the dissolving cylinder 21; a conveying rod 32, which is a spiral shaft, disposed in the conveying channel 31, one end of which passes through the outer surface of the conveying channel 31 and is rotatably disposed on the conveying channel 31, for conveying the salt in the conveying channel 31 from the direction of the storage section 1 to the direction of the dissolving cylinder 21; and a conveying motor 33, which is disposed on the outer surface of the conveying channel 31, and its output shaft is connected to one end of the conveying rod 32 passing through the conveying channel 31, which can drive the conveying rod 32 to rotate.

[0044] An inclined conveying channel 31 is connected at both ends to the lower outlet of the storage section 1 and the upper inlet of the dissolving cylinder 21, respectively. The conveying rod 32 is a spiral shaft placed inside the conveying channel 31. One end of the rod is rotatably mounted on the end cap of the channel near the storage section 1 through a bearing seat, and the other end passes through the end cap at the other end of the channel and extends to the outside. A conveying motor 33 is fixedly mounted on the outer surface of the end cap by a bracket. Its output shaft is directly connected to the extended end of the conveying rod 32 through a coupling, thereby driving the spiral shaft to rotate and stably push the salt powder from the storage section 1 into the dissolving cylinder 21. Due to the inclination of the conveying channel 31, the salt powder will not flow back and contaminate the raw materials when the machine stops.

[0045] Example 7: This embodiment is a further improvement based on any of the above embodiments.

[0046] like Figure 1 As shown, in this embodiment, a liquid outlet channel 6 is also included, which connects the dissolving cylinder 21 and the temporary storage section 4, and is used to introduce the dissolved solution from the dissolving cylinder 21 into the temporary storage section 4. A liquid outlet valve 61 is provided on the liquid outlet channel 6.

[0047] One end of the liquid outlet channel 6 is connected to the outlet at the bottom of the dissolving tank 21, and the other end is connected to the inlet at the top of the temporary storage section 4. It is used to introduce the clarified solution after dissolution from inside the dissolving tank 21 into the temporary storage section 4 for storage. The liquid outlet channel 6 is made of stainless steel pipe, and a liquid outlet valve 61 is installed on the middle pipe to control the flow and flow rate of the solution.

[0048] Example 8: This embodiment is a further improvement based on any of the above embodiments.

[0049] like Figure 1 As shown, in this embodiment, the temporary storage section 4 is a sealed temporary storage cylinder, which is provided with a discharge pipe 41 and a discharge valve 411.

[0050] The temporary storage section 4 is specifically a sealed cylindrical temporary storage tank made of corrosion-resistant stainless steel. A discharge pipe 41 is provided at the bottom of the tank. The discharge pipe 41 penetrates the tank wall and connects to the external delivery pipeline. A discharge valve 411 is installed on the pipeline to precisely control the timing and flow rate of the discharged solution.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
