Description

Technical Field

[0001] The utility model relates to the technical field of batching tanks, in particular to a constant temperature and constant pressure batching tank. Background Art

[0002] The liquid preparation tank is heated by the steam in its jacket. The heat is transferred to the material through the inner wall of the tank, which can maintain the required temperature for the reaction. At the same time, the liquid preparation tank stirs the material by the agitator, and the material is mixed evenly by constantly tumbling the material. It has the characteristics of energy saving, corrosion resistance, high production capacity, easy cleaning, and simple structure. It is an indispensable equipment for manufacturers of dairy products, beverages, and pharmaceuticals. The main body is made of imported stainless steel and is equipped with a jacket, inner tank, head, stirring device and public piping system.

[0003] Chinese patent announcement number CN219722612U discloses an automatic batching tank steam constant temperature device, which drives the stirring rod to rotate when the motor rotates. The stirring rod is used to mix the raw materials. At the same time, the heating box fixed to the bottom of the tank body allows the heated steam to enter the interior of the tank body. The stirring rod is embedded in the top of the heating box, so that the hot air inside the heating box flows through the groove inside the stirring rod. At the same time, one end of the hose connected to the outside of the stirring rod is embedded in the interior of the stirring rod. Through the rotation of the stirring rod, the steam is transported to the interior of the tank body through the hose when the stirring rod rotates, which is effective. The raw materials are now subjected to constant temperature treatment; when the motor rotates, the motor drives the movable rod to rotate inside the tank body, and the outer portion of the movable rod is clamped on the brush, so that the movable rod drives the brush to rotate when it rotates, and the rotation of the brush is used to mix the raw materials on the side wall of the tank body, thereby avoiding the accumulation of raw materials on the inner wall of the tank body. The above technology achieves the purpose of constant temperature treatment by continuously heating the raw materials in the tank body with steam. When excessive low-temperature raw materials are added, the local reaction temperature in the tank will still be affected, causing the reaction to be delayed or terminated, which is not conducive to controlling the reaction products. For this reason, the utility model discloses a constant temperature and constant pressure batching tank for solving the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention solves the above technical problems as follows:

[0006] A constant temperature and pressure batching tank comprises a tank body, a feeding pipe and a pressure relief valve.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] See also Figure 1-6 The utility model provides a constant temperature and constant pressure batching tank, comprising a tank body 1, a feeding pipe 2 and a pressure relief valve 3. A solid feeding port 11 arranged obliquely is embedded on one side of the top of the tank body 1. The solid feeding port 11 is flange-connected to a tank cover 12. A discharge port 13 is provided at the bottom end of the tank body 1. A discharge valve 14 is installed on the discharge port 13.

[0027] Specifically, the inclined solid feeding port 11 helps the solid material to slide smoothly into the tank body 1, the flange connection can ensure the sealing of the connection to prevent material leakage or the entry of external pollutants, and the discharge valve 14 is used to control the discharge of the material, and can accurately adjust the discharge volume to prevent material waste.

[0028] Furthermore, a driving motor 15 is fixedly connected to the top of the tank body 1, and an input end of the driving motor 15 extends into the tank body 1 and is fixedly connected to a stirring impeller 16;

[0029] Specifically, the function of the stirring impeller 16 is to rotate under the drive of the drive motor 15 to stir the material in the tank body 1. The stirring action helps to evenly mix the material, ensure the efficiency and effect of the reaction or mixing process, and also helps to maintain a constant temperature state of the material in the tank, because uniform stirring can avoid local overheating or cooling, and helps to evenly distribute heat throughout the material in the tank.

[0030] Furthermore, a transparent glass strip 17 is fixedly embedded on the front side of the tank body 1, and a scale line 18 is provided beside the transparent glass strip 17 and on the tank body 1;

[0031] Specifically, the transparent glass strip 17 allows the operator to visually observe the material in the tank, and the scale line 18 can clearly indicate the remaining material in the tank, making it easy to control the state and amount of the material so that raw materials can be added or reactants can be removed in time, thereby improving the convenience and accuracy of operation.

[0032] Furthermore, a pressure relief valve 3 is fixedly embedded on one side of the top of the tank body 1;

[0033] Specifically, the excess gas in the tank body 1 is discharged to the exhaust pipe through the pressure relief valve 3, thereby ensuring the safety of the reaction workshop and maintaining a constant pressure state in the batching tank.

[0034] Furthermore, a preheating bin 4 is provided above the tank body 1, and the preheating bin 4 includes a water bin 41 and a bin cover 42. The bin cover 42 is screwed to the upper side of the water bin 41, and a connecting pipe 43 is fixedly embedded on one side of the bottom of the bin cover 42. A plurality of annular lower baffles 44 are fixedly connected to the bottom wall of the water bin 41, and a plurality of annular upper baffles 45 are fixedly connected to the lower side of the bin cover 42. A steam pipe 46 is fixedly embedded in the middle of the bin cover 42, wherein the annular upper baffles 45 and the annular lower baffles 44 are staggered, and the heights of the annular upper baffles 45 and the annular lower baffles 44 are both lower than the height of the water bin 41.

[0035] Specifically, the steam pipe 46 and the connecting pipe 43 are key components for providing steam to the preheating bin 4, which helps to heat the feeding pipe 2 in the water bin 41. The lower baffle 44 and the upper baffle 45 are both annular, and the diameter of each lower baffle 44 and upper baffle 45 is different. The staggered distribution allows a tortuous flow channel to be formed between the water bin 41 and the bin cover 42, thereby extending the heat exchange time between the steam and the feeding pipe 2.

[0036] Furthermore, the feeding pipe 2 is connected to the tank body 1 after passing through the preheating bin 4. The feeding pipe 2 includes an upper pipe 21 fixedly embedded in the bin cover 42 and a lower pipe 22 fixedly embedded in the bottom of the water bin 41. The bottom ends of the lower pipes 22 are fixedly embedded in the top of the tank body 1. The upper pipe 21 is located on the lower side of the bin cover 42 and has a serpentine structure. The bottom ends of the upper pipes 21 are fixedly connected to the intubations 23. The outer sides of the intubations 23 are provided with sealing rings 24, and the intubations 23 are aligned and plugged into the adjacent lower pipes 22.

[0037] Specifically, the upper connecting pipe 21 is designed as a serpentine structure. This design helps to extend the flow path of the liquid raw material in the pipe and increase the heat exchange time with the hot steam, thereby improving the heating efficiency. The function of the lower connecting pipe 22 is to introduce the preheated liquid raw material into the tank body 1. A sealing ring 24 is provided on the outside of each insert pipe 23. When the upper connecting pipe 21 and the lower connecting pipe 22 are aligned, the sealing ring 24 is squeezed by the two to ensure the sealing of the connection. When the bin cover 42 is removed, the insert pipe 23 is pulled out from the lower connecting pipe 22, which can easily clean the inside of the preheating bin 4 or the feeding pipe 2 to prevent scale formation and affect heat exchange.

[0038] Furthermore, a heat distribution pipe 5 is provided on the outside of the tank body 1, and the preheating chamber 4 is connected to the heat distribution pipe 5 through a flow guide pipe 6. The heat distribution pipe 5 is spirally wound around the outer wall of the tank body 1, and a protective sleeve 51 is provided on the outside of the heat distribution pipe 5. The upper and lower sides of the protective sleeve 51 are welded and fixed to the outer wall of the tank body 1, wherein both ends of the heat distribution pipe 5 pass through the protective sleeve 51, and the upper end of the heat distribution pipe 5 is flange-connected to the flow guide pipe 6, and the other end of the flow guide pipe 6 is flange-connected to the connecting pipe 43;

[0039] Specifically, the heat-distributing pipe 5 is connected to the steam pipe 46 and the flow guide pipe 6, allowing high-temperature steam or heating medium to flow in the heat-distributing pipe 5 to heat the tank body 1. The heat-distributing pipe 5 is spirally wound around the outer wall of the tank body 1. This design helps to improve the heating efficiency because it increases the surface area for heat exchange, so that heat can be transferred to the material in the tank body 1 more evenly.

[0040] Working principle: When in use, the initial raw material is put into the tank body 1 from the solid feeding port 11, and the driving motor 15 drives the stirring impeller 16 to stir the raw material. After the tank cover 12 is sealed, high-temperature steam is injected into the uniform heat pipe 5. The high-temperature steam spirally rises along the uniform heat pipe 5 to heat the tank body 1. After that, new liquid raw material is injected into the upper connecting pipe 21, and the liquid raw material zigzags in the upper connecting pipe 21. At the same time, the hot steam is transmitted to the preheating bin 4 through the guide pipe 6. Under the guiding action of the annular upper baffle 45 and the annular lower baffle 44, the hot steam is able to zigzag and converge to the steam pipe 46 for upward discharge. In this process, the liquid raw material in the upper connecting pipe 21 exchanges heat with the hot steam to increase its temperature. The heated liquid raw material flows to the lower connecting pipe 22 and is discharged into the tank body 1 to react with the initial raw material. The excess gas generated by the reaction is discharged to the exhaust pipe by the pressure relief valve 3, which ensures the safety of the reaction workshop, maintains a constant temperature and pressure state in the batching tank, and accelerates the reaction process.
