Description

Technical Field

[0001] The present application relates to the field of food processing equipment, and in particular to a displacement reaction tank mixing device for producing sodium saccharin. Background Art

[0002] At present, the reaction tank is a kind of equipment used for chemical reactions, physical and chemical processes and laboratory research. It is usually made of steel plates of a certain thickness, with high corrosion resistance and high temperature and high pressure bearing capacity. It is widely used in pharmaceutical, chemical, food processing and other fields to meet the needs of different processes. According to different process requirements, it can be divided into atmospheric pressure reaction tank, high pressure reaction tank, vacuum reaction tank and other types. It can accommodate chemical reactions under high pressure and high temperature conditions, and can be heated or cooled during the reaction process to adjust the reaction rate and product yield. It is widely used in pharmaceutical, polymer industry, organic synthesis and other fields, and is a sharp tool in the chemical industry.

[0003] In the process of producing saccharin sodium, there is an important process step, that is, pre-cooling the diazonium salt solution and introducing sulfur dioxide after the temperature reaches the required level. The current method of introducing sulfur dioxide is to directly introduce sulfur dioxide into the reaction tank.

[0004] The above-mentioned prior art solutions have the following defects: sulfur dioxide is directly introduced into the reaction tank, resulting in the problem of uneven distribution of sulfur dioxide. Utility Model Content

[0005] In order to achieve more uniform gas distribution when the gas is introduced into the reaction tank, the present application provides a displacement reaction tank mixing device for the production of sodium saccharin.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A replacement reaction tank mixing device for the production of sodium saccharin comprises a reaction tank, a frame and a gas distribution structure arranged on an agitator in the reaction tank, the frame is fixedly connected to a working surface, the reaction tank is fixedly connected to the frame, the gas distribution structure comprises an air inlet pipe and a branch pipe, the air inlet pipe is buried in a stirring shaft of the agitator, the air inlet pipe is fixedly connected to the stirring shaft, a plurality of branch pipes are arranged, a branch pipe is correspondingly buried in each stirring rod of the agitator, and each branch pipe is connected to the air inlet pipe; a plurality of first air holes are arranged on each branch pipe, a plurality of second air holes are arranged on each stirring rod corresponding to the plurality of first air holes, the first air holes are connected to the second air holes, and the gas is distributed to the reaction tank through the first air holes and the second air holes.

[0008] By adopting the above scheme, an air intake pipe is buried in the stirring shaft, and external gas is introduced into the air intake pipe. Since branch pipes are buried in a plurality of stirring rods, the gas input into the air intake pipe is evenly transmitted to the branch pipes. Since the first air vents are provided, the gas entering the branch pipes is discharged to between the outer wall of the branch pipes and the inner wall of the stirring rods through the plurality of first air vents. Since the second air vents are provided, the gas is discharged into the reaction tank through the second air vents, thereby achieving a more uniform distribution of the gas entering the reaction tank from the outside.

[0009] Furthermore, a first guide plate is arranged between the first air hole and the second air hole, and a plurality of first guide plates are arranged, and the plurality of first guide plates are evenly distributed between the first air hole and the second air hole, and both ends of each first guide plate are respectively fixedly connected to the inner wall of the stirring rod and the outer wall of the branch pipe, and the plurality of first guide plates are used to discharge each gas discharged through the first air hole into the reaction tank through the second air hole corresponding thereto.

[0010] By adopting the above scheme, since each air hole corresponds to a second air hole, the guide plate separates several first air holes, and since the two ends of the guide plate are respectively fixedly connected to the inner wall of the stirring rod and the outer wall of the branch pipe, that is, each first air hole and the corresponding second air hole are divided into a ventilation unit, thereby achieving the effect of diverting the gas.

[0011] Furthermore, each of the first guide plates is correspondingly provided with a second guide plate, each of the second guide plates is provided on the outer wall of the stirring rod, and each of the second guide plates is fixedly connected to the outer wall of the stirring rod.

[0012] Furthermore, one end of each second guide plate away from the outer wall of the stirring rod is fixedly connected to a curved rod, one end of the curved rod is fixedly connected to the second guide plate, and the other end of the curved rod is arranged opposite to the second vent hole.

[0013] By adopting the above scheme, the second guide plate is used to perform secondary diversion of the gas output through the second air hole. After the gas is output through the second air hole, it will generate bubbles with the solution in the reaction tank. The bubbles will cause the mixing between the gas and the solution to be uneven. Because an arc rod is provided on the second guide plate, the arc rod can puncture the bubbles generated by the gas output through the second air hole and the solution, thereby making the mixing of the gas and the solution more even.

[0014] Furthermore, a piercing member is fixedly connected to one end of the arc rod away from the second guide plate, and the piercing member includes a flat end and a pointed end. The flat end is fixedly connected to the arc rod, and the pointed end is arranged opposite to the second air vent. The piercing member is used to pierce bubbles generated by the gas transported through the second air vent and the liquid in the reaction tank.

[0015] By adopting the above solution, a tip is provided at one end of the piercing member. Compared with the arc-shaped rod, the force-bearing area between the tip and the bubble is smaller, thereby being able to pierce the bubble faster.

[0016] Furthermore, each supporting leg on the frame is provided with a movable component, and the movable component is fixedly connected to each supporting leg. A groove is provided at the end of each supporting leg close to the working surface, and a support block is provided in each groove. The support block is slidably connected to the groove, and a fixing rod is also provided between the support block and the groove. The fixing rod passes through the side wall of the groove and abuts against the support block, and the fixing rod is threadedly connected to the side wall of the groove; when the support block slides into the groove, the movable component abuts against the working surface.

[0017] By adopting the above scheme, a moving component is arranged on the support leg, and the moving component is used to drive the reaction tank to move along the working surface. Since the support block and the groove are slidably connected, when the support block is pushed to the end away from the working surface, the overall length of the support leg is shortened. At this time, the moving component abuts against the working surface, thereby enabling the reaction tank as a whole to be displaced. The fixed rod is used to lock the relative position relationship between the support block and the groove. When the relative position between the support block and the groove is determined, the fixed rod is rotated, and the fixed rod passes through the side wall of the groove and is fixedly connected to the support block, thereby completing the locking of the position relationship between the support block and the inner wall of the groove.

[0018] Furthermore, the moving assembly includes a ring, a connecting rod and a roller, the ring is sleeved on the supporting leg, the ring is fixedly connected to the supporting leg, one end of the connecting rod is fixedly connected to the ring, and the other end of the connecting rod is fixedly connected to the roller.

[0019] Furthermore, a stabilizing rod is provided between the connecting rod and the supporting leg, and two ends of the stabilizing rod are fixedly connected to the connecting rod and the supporting leg respectively.

[0020] By adopting the above scheme, since a connecting rod and a ring are provided, the roller can be fixedly connected to the ring through the connecting rod, and fixedly connected to the support leg through the ring. Since a stabilizing rod is provided between the support leg and the connecting rod, a triangle is formed between the support leg, the connecting rod and the stabilizing rod. Since the triangle has stability, the connection between the moving component and the support leg is more stable.

[0021] In summary, this application has the following technical effects:

[0022] 1. By setting up a gas distribution structure, an air inlet pipe is buried in the stirring shaft, and external gas is introduced into the air inlet pipe. Since branch pipes are buried in a plurality of stirring rods, the gas input into the air inlet pipe is evenly transmitted to the branch pipes. Since the first air vents are provided, the gas entering the branch pipes is discharged to between the outer wall of the branch pipes and the inner wall of the stirring rods through the plurality of first air vents. Since the second air vents are provided, the gas is discharged into the reaction tank through the second air vents, thereby achieving a more even distribution effect of the gas entering the reaction tank from the outside;

[0023] 2. By setting up the first guide plate, since each vent hole corresponds to a second vent hole, the guide plate separates a plurality of first vent holes, and since the two ends of the guide plate are respectively fixedly connected to the inner wall of the stirring rod and the outer wall of the branch pipe, that is, each first vent hole and the corresponding second vent hole are divided into a ventilation unit, achieving the effect of gas diversion;

[0024] 3. By providing an arc rod, the arc rod can puncture the bubbles generated by the gas and solution output through the second vent hole, thereby making the gas and solution mix more evenly. BRIEF DESCRIPTION OF THE DRAWINGS
