Description

Technical Field

[0001] This utility model relates to the technical field of choline chloride transfer equipment, specifically a dehumidifying silo for choline chloride. Background Technology

[0002] Choline chloride is a white hygroscopic crystal with strong deliquescent properties. When exposed to a humid environment, it easily absorbs moisture and clumps, which can even lead to fermentation and spoilage of plant-based products.

[0003] Currently, the production process of choline chloride requires drying. To ensure drying quality, the amount of material dried each time is relatively small, generally one or two hundred kilograms. Different batches of choline chloride often have differences in moisture content and other properties. To ensure consistent material quality, a mixing operation is required, where multiple batches of dried material are mixed evenly before packaging. However, due to the strong hygroscopic nature of choline chloride, existing ordinary mixing equipment can cause the choline chloride to absorb moisture during temporary storage and mixing, resulting in moisture content exceeding the standard and affecting the overall quality of the mixed batches. Utility Model Content

[0004] The purpose of this invention is to provide a dehumidifying silo for choline chloride. The dehumidifying silo allows for the mixing and temporary storage of different batches of dried choline chloride, effectively reducing the hygroscopic clumping of the choline chloride inside and solving the problems in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a dehumidifying silo for choline chloride, including a discharge rack, a silo frame installed on the discharge rack, a weighing instrument at the bottom of the silo frame, a temporary storage tank installed inside the silo frame, a discharge pipe connected to the bottom of the temporary storage tank, a switch valve installed on the discharge pipe, the discharge pipe can pass downward through the discharge rack, an inlet valve is installed at the top of the temporary storage tank, and a rotatable flap is installed inside the temporary storage tank. When the flap is closed, it can isolate the interior of the temporary storage tank into two empty spaces. The chamber contains several perforated tubes arranged side by side inside a temporary storage tank on the upper side of the flap. Each perforated tube contains a replaceable desiccant pack. Corresponding to the position of the perforated tube, an openable and closable inspection door is provided on the temporary storage tank. Inside the temporary storage tank above the perforated tube, there is a rotatable material leveling bracket. At the bottom of the material leveling bracket, there are several stirring rods arranged along the length direction. When the flap is closed, after the material entering the temporary storage tank reaches the set weight, the flap and the switch valve open, and the material in the temporary storage tank is discharged together through the discharge pipe. The temporary storage tank has a conical barrel at its bottom, with a connecting discharge pipe at the bottom. Both sides of the discharge pipe have connecting wet material filter pipes on their inclined surfaces. Two relatively inclined filter plates are installed inside the conical barrel, positioned above the discharge pipe and between the discharge pipe and the wet material filter pipe. The upper surface of the filter plates corresponds to the inner surface of the wet material filter pipe. Dry, small-diameter particles filtered by the filter plates enter the discharge pipe, while larger-diameter wet particles enter the wet material filter pipe. The wet material filter pipe has a slot frame with a removable insert plate. The end of the insert plate extending beyond the wet material filter pipe has a gripping handle. A material recovery box is also connected to the end of the wet material filter pipe. The temporary storage tank is equipped with two sets of hinged flaps that open and close together. Each flap is hinged to the inner wall of the tank via a pivot. A telescopic cylinder is hinged between the bottom of the flap and the inner wall of the tank. The ends of the flaps that meet are provided with interlocking folded flanges. When the piston rod of the telescopic cylinder extends, the flaps on both sides can rotate and connect, isolating the interior of the temporary storage tank into two cavities. The tank body consists of an outer cylinder wall, an inner cylinder wall, and a heat insulation layer between them. A maintenance climbing frame is installed on one side of the hopper frame. A motor is installed on the top side of the temporary storage tank. A vertically arranged shaft is located at the center of the material leveling support. A first drive wheel is installed on the output shaft of the motor. A second drive wheel is installed at the end of the shaft that extends upward through the temporary storage tank. A drive belt is installed between the first and second drive wheels. When the motor starts, it drives the material leveling support to rotate inside the temporary storage tank.

[0006] The positive effects of this invention are as follows: The dehumidifying silo for choline chloride described herein, by incorporating a perforated tube and an internal desiccant pack within the temporary storage tank, allows for the drying of the tank itself and further dehumidifies and dries the choline chloride entering the tank. This effectively reduces its moisture content, minimizes clumping caused by moisture absorption, and ensures stable quality of choline chloride after mixing different batches, meeting customers' requirements for consistency in large-volume products. Simultaneously, the uniform mixing support ensures thorough and even mixing of the materials, further guaranteeing consistent material quality and improving product quality. Furthermore, this dehumidifying silo has a large temporary storage capacity, enabling the centralized mixing and temporary storage of multiple batches of dried choline chloride, meeting customers' needs for large-volume batch delivery. Once the material reaches the set weight, the flap and valve open, allowing the material to be discharged simultaneously, achieving rapid and continuous batch mixing operations, significantly improving production efficiency and reducing the time and labor costs associated with frequent packaging.

Detailed Implementation

[0008] The present invention describes a dehumidifying silo for choline chloride, such as... Figure 1-3As shown, the system includes a discharge rack 1, the bottom of which can hold packaging bags containing mixed batches of choline chloride. A hopper rack 2 is mounted on the discharge rack 1, and a weighing instrument 3 is installed at the bottom of the hopper rack 2. A temporary storage tank 4 is installed inside the hopper rack 2. The temporary storage tank 4 is used to hold different batches of dried choline chloride and maintain the dryness of the material. The weighing instrument 3 is used to monitor the mass of the material falling into the temporary storage tank 4 in real time. Once a specified mass is reached, the material is dropped uniformly to ensure the quality of the mixed batches. The weighing instrument 3 can be composed of multiple N10A circular plate-type weighing force sensors, arranged circumferentially at the bottom of the hopper rack 2 to achieve the corresponding weighing function.

[0009] The bottom of the temporary storage tank 4 is provided with a connected discharge pipe 27. A switch valve 5 is installed on the discharge pipe 27. The discharge pipe 27 can pass downward through the discharge rack 1. A packaging bag is placed at the bottom of the discharge pipe 27. After the material mass in the temporary storage tank 4 accumulates to a set value, the switch valve 5 is opened to allow the material inside to fall into the packaging bag.

[0010] A feed valve 6 is installed at the top of the temporary storage tank 4. Materials dried in different batches sequentially enter the temporary storage tank 4 through the feed valve 6 for accumulation. To achieve the accumulation and storage of materials in the temporary storage tank 4, a rotatable flap 7 is installed inside the tank. When closed, the flap 7 isolates the interior of the temporary storage tank 4 into two cavities. Several perforated tubes 8 are installed side-by-side inside the temporary storage tank 4 above the flap 7. Each perforated tube 8 contains a replaceable desiccant pack 28, which dehumidifies the temporarily stored materials and maintains their dryness. Corresponding to the positions of the perforated tubes 8, an openable inspection door 29 is provided on the temporary storage tank 4. After the desiccant pack 28 reaches moisture saturation, the inspection door 29 can be opened periodically to replace the desiccant pack 28 in the perforated tubes 8, ensuring the performance of the device during use. The outer layer of the desiccant pack 28 can be a non-woven fabric material, which can absorb moisture while preventing the desiccant from contacting the material. Alternatively, the inner wall of the perforated tube 8 can be covered with a breathable membrane material, which allows contact with pharmaceutical materials such as choline chloride without contaminating the material or causing it to deteriorate, while also enabling the desiccant pack 28 to absorb moisture and dry.

[0011] The temporary storage tank 4 at the top of the perforated tube 8 is equipped with a rotatable material-leveling support 9. Several stirring rods 30 are arranged along the length of the support 9 at its bottom. The stirring rods 30 themselves do not have rotational power; the support 9 rotates synchronously with the stirring rods 30 to achieve thorough mixing of the temporarily stored material in the tank, ensuring consistent quality in large batches. The distances between the perforated tube 8 and the flap 7, and between the support 9 and the perforated tube 8, are relatively small, allowing for thorough mixing of the choline chloride material in the temporary storage space without affecting the rotation of the support 9.

[0012] When the flap 7 is closed, the material entering the temporary storage tank 4 accumulates in the cavity above the flap 7. Once the set weight is reached, the flap 7 and the switch valve 5 open, and the material in the temporary storage tank 4 is discharged through the discharge pipe 27. The perforated pipe 8 and the internal desiccant pack 28 maintain the dryness of the material in the cavity above the flap 7. The rotation of the material leveling bracket 9 allows the material entering the temporary storage tank 4 to be evenly spread and fully mixed, preventing excessive accumulation and moisture absorption.

[0013] When using the dehumidifying silo for choline chloride of this invention, the material after different batches of drying treatment is first accumulated and stored in the temporary storage tank 4. At this time, the flap 7 and the switch valve 5 are both rotated and closed. The material after each batch of drying treatment enters the temporary storage tank 4 under the control of the feed valve 6. The desiccant pack 28 in the perforated tube 8 maintains the dryness of the material storage space. The material is fully mixed by the rotation of the uniform support 9 and the stirring rod 30. After the material accumulates to the set weight value, the feed valve 6 closes and no more material enters. A packaging bag is placed at the bottom of the discharge pipe 27, the switch valve 5 is opened, and the flap 7 is rotated and opened. Under the action of gravity, all the material in the temporary storage tank 4 falls into the packaging bag for uniform packaging and sealing treatment, thereby ensuring the quality of mixed batches of material and meeting the large-volume needs of customers. The above-mentioned valve settings can effectively ensure the sealing and drying performance of the tank body.

[0014] Furthermore, to ensure the quality of mixed batch materials as they fall into the packaging bag, moisture-absorbing and clumping materials during the falling process are screened and removed, such as... Figure 4 As shown, the bottom of the temporary storage tank 4 is provided with a conical barrel, and the bottom end of the conical barrel is provided with a connected discharge pipe 27. Both sides of the conical barrel inclined surface on the discharge pipe 27 are provided with connected wet material filter pipes 10. The material that absorbs moisture and clumps can be discharged through the wet material filter pipes 10.

[0015] Two relatively inclined filter plates 11 are installed inside the cone. The two filter plates 11 are located on the upper side of the feed pipe 27, between the feed pipe 27 and the wet material removal pipe 10. The upper surface of the filter plate 11 corresponds to the inner cavity surface of the wet material removal pipe 10. In this way, the area enclosed by the two filter plates 11 can isolate the feed pipe 27 from the wet material removal pipes 10 on both sides. After the material comes into contact with the filter plate 11 during the falling process, the dry small-diameter material filtered by the filter plate 11 enters the feed pipe 27, while the large-diameter wet material enters the wet material removal pipe 10. This screens out the material that absorbs moisture and clumps, avoids the wet material from being mixed into qualified products, further optimizes the quality of the material, and ensures the quality of the material entering the packaging bag through the feed pipe 27.

[0016] The tops of the two filter plates 11 form a very small angle, so the falling material will not accumulate at the top of the filter plates 11, but will fall along the filter plates 11 on both sides, filtering out the moisture-absorbing and clumping material inside, without affecting the normal falling of the material.

[0017] Furthermore, in order to isolate the wet material filter tube 10 from the external environment and prevent humid air from entering the temporary storage tank 4 through the wet material filter tube 10 during non-discharge operations, a slot frame 12 is provided on the wet material filter tube 10. A pluggable insert plate 13 is installed in the slot frame 12. A gripping handle 14 is provided at one end of the insert plate 13 that extends out of the wet material filter tube 10. A material recovery box 15 is also provided at the end of the wet material filter tube 10.

[0018] When materials are accumulated and stored in the temporary storage tank 4, the insert plate 13 is installed in the slot frame 12 to block the wet material filter tube 10, effectively isolating the outside humid air. When the material accumulates to the set value and a unified material discharge operation is performed, the staff manually pulls out the insert plate 13. The large-diameter material that has absorbed moisture and clumps enters the material recycling box 15 under the guidance of the filter plate 11. The material recycling box 15 is set to facilitate the recycling or reprocessing of wet materials, reduce material loss and save production costs.

[0019] Furthermore, in order to realize the opening and closing drive of the flap 7, two sets of flaps 7 are hingedly installed inside the temporary storage tank 4. Each flap 7 is hinged to the inner wall of the temporary storage tank 4 through a rotating shaft. A telescopic cylinder 16 is hinged between the bottom of the flap 7 and the inner wall of the tank. The ends of the flaps 7 that are in contact with each other are provided with mutually cooperating folded flanges 17. When the piston rod of the telescopic cylinder 16 extends, the flaps 7 on both sides can rotate and connect to isolate the interior of the temporary storage tank 4 into two cavities. When the piston rod of the telescopic cylinder 16 retracts, the flaps 7 on both sides can rotate and open to allow the accumulated material to be discharged together.

[0020] Two sets of hinged flaps 7, which open and close together, are controlled by a telescopic cylinder 16 to achieve precise on / off control. When the flaps 7 are closed, the interior of the storage tank 4 is divided into two cavities. The upper cavity is used for temporary storage of materials, and a relatively dry environment is maintained through the internal perforated tube 8 and desiccant pack 28, facilitating phased temporary storage of materials. When the material reaches a set quantity and discharge is required, the flaps 7 open quickly to allow the material to be discharged smoothly. The folded flanges 17 at the mating ends of the flaps 7 enhance the sealing of the connection, effectively reducing gas exchange between the upper and lower cavities, maintaining the dryness of the material storage space, and thus ensuring the quality of the falling material.

[0021] Furthermore, in order to minimize the impact of temperature differences in the external environment and reduce the generation of condensate inside the tank, the temporary storage tank 4 is composed of an outer cylinder wall 18, an inner cylinder wall 19, and a heat insulation layer 20 between them. The heat insulation layer 20 can effectively isolate the impact of temperature differences in the external environment, thereby ensuring the dryness of the internal materials and guaranteeing the quality of the materials during mixed batch temporary storage.

[0022] Furthermore, to facilitate the inspection and maintenance of the entire device, a maintenance climbing frame 21 is installed on one side of the hopper frame 2. To achieve the rotational drive of the material leveling support 9, a motor 22 is installed on one side of the top of the temporary storage tank 4. A vertically arranged shaft 23 is provided at the center of the material leveling support 9. A first transmission wheel 24 is installed on the output shaft of the motor 22. A second transmission wheel 25 is installed at the end of the shaft 23 that extends upward through the temporary storage tank 4. A transmission belt 26 is installed between the first transmission wheel 24 and the second transmission wheel 25. When the motor 22 is started, it can drive the material leveling support 9 to rotate inside the temporary storage tank 4.

[0023] The maintenance climbing frame 21 installed on one side of the hopper frame 2 provides operators with a convenient maintenance passage, facilitating daily inspection and maintenance of the equipment. The installation of transmission mechanisms such as the motor 23, drive wheel, and drive belt 26 makes the rotation control of the material distribution support 9 more convenient, and the structure is simple, reliable, easy to maintain and replace, reducing the equipment's operation and maintenance costs.

[0024] The dehumidifying silo for choline chloride described in this invention has many advantages, such as preventing moisture absorption and clumping, efficient batch mixing, precise filtration, easy cleaning, good heat insulation performance, and convenient inspection and maintenance. It can effectively solve the problems existing in the prior art, improve the production quality and efficiency of choline chloride, reduce production costs, and has broad market application prospects.
