Description

Technical Field

[0001] This utility model relates to the field of material anti-caking technology, and in particular to a bottom-discharge sugar-dissolving tank. Background Technology

[0002] A sterile sugar storage container is used for the uncontaminated storage of free-flowing materials such as powders, granules, or liquids. However, existing technology presents certain discharge problems, particularly as the material level decreases, leading to clumping. This not only makes material discharge difficult but can also affect production efficiency and product quality. The problem is exacerbated when the discharge port is not at the bottom. We analyzed some causes of clumping: First, when storing powders or granules, increased humidity inside the container causes the powder or granules, such as sugar, to absorb moisture, resulting in deliquescence and dissolution, which easily leads to clumping after re-drying. Second, if the powder or granules, such as sugar, have excessive moisture content, large temperature fluctuations in the storage environment can also cause clumping. This is because when moist sugar dries, a hard syrup film forms on the surface of the sugar crystals, causing the sugar to bind into hard lumps. Third, microbial contamination, such as from bacteria or fungi, can also cause sugar to clump.

[0003] Application number 202322588079.1 describes a storage tank for preventing sucrose caking. This tank utilizes a perforated airflow distribution plate at the connection between the tank body and the conical section. This allows the airflow blowing in from the conical section to be evenly distributed and enter the tank interior, effectively purging the sucrose and preventing caking during storage. However, this solution cannot guarantee that powder or small particles will slide off the perforated airflow and leave the storage space. Furthermore, it cannot ensure that the high-pressure air is heated at the same temperature, which can cause the sucrose to suddenly encounter a cold airflow, releasing moisture and leading to caking. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a bottom-discharge sugar storage tank that prevents spoilage of stored materials and inhibits clumping caused by microorganisms. High-pressure drying gas is introduced into the bottom of the material to remove moisture and loosen particles, thus helping to prevent clumping. The tank is heated at the same temperature, which prevents the material from melting due to a sudden temperature increase or dissolving due to a sudden temperature decrease.

[0005] To achieve the above objectives, this utility model provides a bottom-discharge sugar dissipation tank, including a tank body, an inlet at the top of the tank body, an outlet at the bottom of the tank body, and an outlet pipe connected to the outlet.

[0006] The tank body is fitted with a sleeve to form a cavity between the tank body and the sleeve. The top of the sleeve is connected to a steam inlet pipe, and the bottom of the sleeve is connected to a steam outlet pipe.

[0007] The inner wall of the tank is provided with several vent pipes, which are located on different axial planes of the tank. The top end of the vent pipe is connected to the outside of the tank, and the bottom end of the vent pipe is close to the bottom of the tank and has an opening. The side wall of the vent pipe is provided with several through holes.

[0008] Furthermore, the tank body includes a cylindrical section, the bottom of which is connected to a conical section, and the discharge port is located at the tip of the conical section;

[0009] The outer can is fitted onto the lower half of the cylindrical section and the conical section;

[0010] A main vent pipe is provided around the tank body on the outer wall of the cylindrical section near the conical section. The main vent pipe is connected to the vent pipe and also to a high-pressure air inlet pipe.

[0011] Furthermore, the high-pressure air inlet pipe extends from the top of the outer shell into the interlayer cavity, and the high-pressure air inlet pipe is connected to the main ventilation pipe;

[0012] The high-pressure air intake pipe is located in the interlayer cavity and has a serpentine bend section.

[0013] Furthermore, the vent pipe is formed by a half-circular pipe attached to the tank body, and the cross-section of the half-circular pipe is a semi-circle with outward flanges connected on both sides.

[0014] The through hole is located near the outer flange of the half-circular tube.

[0015] Furthermore, the lengths of adjacent half-circular tubes are different.

[0016] Furthermore, the discharge pipe is connected to a stop valve one, and a sewage branch pipe is provided near the stop valve one and between the stop valve one and the discharge port, and the sewage branch pipe is connected to a stop valve two.

[0017] Furthermore, the steam inlet pipe is equipped with a regulating valve, and the steam outlet pipe is equipped with a shut-off valve.

[0018] Furthermore, the high-pressure air intake pipe is equipped with a regulating valve two.

[0019] Furthermore, the top of the tank is connected to an exhaust pipe, and the exhaust pipe is connected to a shut-off valve.

[0020] Furthermore, the tank body, the outer casing, and the vent pipe are all made of stainless steel, and the tank body, the outer casing, and the vent pipe are all welded by argon arc welding.

[0021] The beneficial effects of this solution can be understood from the description of the solution above:

[0022] (1) The tank body is equipped with a jacket to form a double-layer cavity, and the double-layer cavity is connected to the steam inlet pipe to introduce steam to kill microorganisms in the tank body. This not only avoids the deterioration of the stored food, but also prevents the clumping of microorganisms.

[0023] (2) A vent pipe is installed at the bottom of the tank, which is connected to a high-pressure air inlet pipe. The bottom end of the vent pipe and the side wall are provided with through holes, so that dry high-pressure gas can be released at the bottom of the tank. When the exhaust valve at the top of the tank is opened, the release of dry gas will draw away a certain amount of moisture in the tank; and due to the release of air pressure, the powder or particles in the tank will be loosened. In this way, moisture is removed on the one hand, and particles are loosened on the other hand, which helps to prevent agglomeration.

[0024] (3) The high-pressure air inlet pipe is located in the interlayer cavity and has a serpentine bend section to heat and dry the high-pressure air, and heat it to the same temperature as the outside of the tank. In this way, the high-pressure drying gas is released inside the tank without causing temperature changes in the material. It will not melt due to a sudden temperature rise, nor will it dissolve due to a sudden temperature drop and precipitation of moisture. This beneficial effect complements the beneficial effect mentioned above.

[0025] (4) High-pressure gas is used to prevent caking. On the one hand, it can transport dry air to remove moisture, and on the other hand, the high-pressure gas will disperse and penetrate into the gaps of powder and particles, and will not cause the material to caking due to macroscopic compression.

[0026] (5) The vent pipe is a half-circular pipe that fits into the tank body, which avoids the formation of new dead corners in the tank body due to the installation of the vent pipe, thereby avoiding the formation of putrefactive substances and clumps.

[0027] (6) The bottom of the vent is open, so that powder or particles entering the vent will slide out from the opening, thus avoiding the powder or particles from being stuck after entering the vent. Attached Figure Description

[0032] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0033] like Figure 1 As shown, this embodiment is a bottom-discharge sugar dissipation tank, including a tank body 1. The top of the tank body 1 is provided with a feed inlet 2. The tank body 1 includes a cylindrical section. The bottom of the cylindrical section is connected to a conical section. The bottom of the conical section is provided with a discharge outlet 3. The discharge outlet 3 is connected to a discharge pipe 4. The discharge pipe 4 is connected to a stop valve 5. A drain branch pipe 6 is provided near the stop valve 5 and between the stop valve 5 and the discharge outlet 3. The drain branch pipe 6 is connected to a stop valve 7.

[0034] A sleeve tank 8 is fitted onto the outside of the tank body 1, forming a cavity 9 between the tank body 1 and the sleeve tank 8. The sleeve tank 8 fits onto the lower half of the cylindrical section and the conical section. A steam inlet pipe 10 is connected to the top of the sleeve tank 8, and a steam outlet pipe 11 is connected to the bottom of the sleeve tank 8. A regulating valve 12 is installed on the steam inlet pipe 10, and a shut-off valve 13 is installed on the steam outlet pipe 11.

[0035] like Figure 2 As shown, eight vent pipes 14 are provided on the inner wall of the tank body 1. The vent pipes 14 are located on different axial planes of the tank body 1. The top of the vent pipe 14 connects to the outside of the tank body 1, and the bottom of the vent pipe 14 is close to the bottom of the tank body 1 and has an opening. The side wall of the vent pipe 14 has some through holes 15. A main vent pipe 16 is provided on the outer wall of the cylindrical section near the conical section, surrounding the tank body 1. The main vent pipe 16 is connected to the vent pipes 14 and is also connected to a high-pressure air inlet pipe 17. The high-pressure air inlet pipe 17 enters the interlayer cavity 9 from the top of the outer tank 8 and is connected to the main vent pipe 16. The high-pressure air inlet pipe 17 has a serpentine bend section in the interlayer cavity 9. The high-pressure air inlet pipe 17 is equipped with a regulating valve 18.

[0036] like Figure 3 As shown, the vent pipe 14 is formed by a half-circular pipe 19 attached to the tank body 1. The cross-section of the half-circular pipe 19 is a semi-circle with outward flanges connected on both sides; the half-circular pipe 19 has a through hole 15 near the outward flange. The lengths of adjacent half-circular pipes 19 are different.

[0037] The top of the tank 1 is connected to an exhaust pipe 20, and the exhaust pipe 20 is connected to a shut-off valve 21.

[0038] Tank 1, sleeve tank 8 and vent pipe 14 are all made of stainless steel, and tank 1 and sleeve tank 8 and vent pipe 14 are all welded by argon arc welding.

[0039] During use, powdered or granular materials are fed into the tank through inlet 2, which also serves as an inlet for visual inspection of the interior of the tank 1. After the materials are stored, they are removed using airflow extraction from the bottom of the tank 1. This method of removing the bottom material first prevents it from being compressed for too long and thus clumping. To eliminate microorganisms, steam is introduced into the cavity 9 of the outer wall of the tank 1 via steam inlet pipe 10. Steam or condensate is discharged via exhaust pipe 20. To further prevent material clumping, dry air is periodically introduced through high-pressure air inlet pipe 17. The dry air absorbs the moisture released from the materials, and because it is under high pressure, when the pressure above the materials is lower than the pressure at the bottom, the materials become loose under the airflow. If the pressure inside the tank 1 is increased first and then suddenly released, the particles inside the tank 1 may even "boil." After the high-pressure air inlet pipe 17 enters the interlayer cavity 9, the serpentine bend will prolong the heat exchange time between the high-pressure drying air and the water vapor in the interlayer cavity 9, so that the temperature of the high-pressure drying air and the material in the tank 1 is consistent, avoiding the material from precipitating water when it gets cold, and also avoiding the material from melting due to excessive temperature.

Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above.
