Description

Technical Field

[0001] This utility model belongs to the technical field of succinic acid production mixing device, and particularly relates to succinic acid production mixing device. Background Technology

[0002] Succinic acid, also known as succinic acid, is an important organic dicarboxylic acid with wide applications in chemical, pharmaceutical, and food industries. In the production of succinic acid, the uniformity and efficiency of material mixing directly affect product quality and production efficiency.

[0003] Existing mixing devices have poor stirring effect and are difficult to adapt to the large viscosity changes of materials during succinic acid production, which easily leads to uneven mixing of succinic acid materials and excessively long stirring time. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution: A succinic acid production mixing device includes: a mixing tank, a variable speed motor, and a stirring assembly. The stirring assembly is located inside the mixing tank and includes a stirring rod and multiple mixing blades. The mixing blades are fixedly connected to the stirring rod via connecting rods. The mixing blades are hollow and have several through holes on their surface. A sealing plate is provided at the position of each through hole. A limiting rod that is fixedly connected to the through hole is movably inserted inside the sealing plate. A return spring is sleeved on the surface of the limiting rod.

[0005] As a preferred embodiment of the above technical solution, the mixing plate is inclined relative to the stirring rod, and the included angle between the mixing plate and the stirring rod is in the range of 15-35 degrees.

[0006] As a preferred embodiment of the above technical solution, the stirring assembly further includes a guide cylinder, one end of which is flared and the other end of which is curved, and the curved end of the guide cylinder is fixedly connected to the bottom of the mixing plate.

[0007] As a preferred embodiment of the above technical solution, the stirring assembly further includes multiple counterweights, which are fixedly connected to corresponding sealing plates.

[0008] As a preferred embodiment of the above technical solution, the through hole is inclined relative to the mixing plate, and the included angle between the through hole and the mixing plate is in the range of 10-20 degrees.

[0009] The beneficial effects of this utility model are as follows: 1. By using a variable speed motor to drive the stirring rod to rotate at different speeds, and using centrifugal force to control the opening and closing of the mixing plates, an adaptive mixing mechanism is achieved. The mixing plates at different positions open at different speeds due to differences in centrifugal force, so that the bottom material enters the mixing area from different heights at different stages, which significantly improves the mixing uniformity. 2. The inclined setting of the mixing plate, the inclined design of the through hole, and the application of the guide cylinder together enhance the axial flow and turbulence effect of the material, further improving the mixing efficiency.

[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0013] Figures 1-3 The mixing device for succinic acid production includes a mixing tank, a variable speed motor, and a stirring assembly. The stirring assembly is located inside the mixing tank and includes a stirring rod 10 and multiple mixing plates 20. One end of the stirring rod 10 extends through the mixing tank to the outside, and the end of the stirring rod 10 is fixedly connected to the output end of the variable speed motor. The mixing plates 20 are fixedly connected to the stirring rod 10 via connecting rods 30. The mixing plates 20 are hollow and have several through holes 40 on their surface. A sealing plate 50 is provided at the position of each through hole 40. A limiting rod 60, which is fixedly connected to the through hole 40, is movably inserted into the sealing plate 50. A return spring 70 is sleeved on the surface of the limiting rod 60. The variable speed motor drives the stirring rod 10 to rotate at a variable speed, and the mixing plates 20 rotate accordingly. As the centrifugal force increases, the mixing plates 20 towards the stirring rod 10 gradually open, allowing the material entering from the bottom to exit from the through holes at different positions, thus completing the mixing process.

[0014] The mixing plate 20 is inclined relative to the stirring rod 10, and the included angle between the mixing plate 20 and the stirring rod 10 is in the range of 15-35 degrees.

[0015] The stirring rod 10 is driven to rotate at different speeds by a variable speed motor, and the opening and closing of the mixing plate 20 is controlled by centrifugal force, thus realizing an adaptive mixing mechanism. The mixing plate 20 at different positions opens at different speeds due to the difference in centrifugal force, so that the bottom material enters the mixing area from different heights at different stages, which significantly improves the mixing uniformity.

[0016] Figures 1-3 In the process, the stirring assembly also includes a plurality of counterweights 90, which are fixedly connected to the corresponding sealing plates 50.

[0017] The through hole 40 is inclined relative to the mixing plate 20, and the included angle between the through hole 40 and the mixing plate 20 is in the range of 10-20 degrees.

[0018] The stirring assembly also includes a guide cylinder 80, one end of which is funnel-shaped and the other end of which is curved, and the curved end of the guide cylinder 80 is fixedly connected to the bottom of the mixing plate 20.

[0019] The inclined arrangement of the mixing plate 20, the inclined design of the through hole 40, and the application of the guide cylinder 80 together enhance the axial flow and turbulence of the material, further improving the mixing efficiency. Meanwhile, the counterweight 90 allows for adjustment of the opening threshold of the sealing plate 50 as needed, enabling the mixing device to adapt to different material characteristics and mixing stages, thus improving the device's versatility and adaptability.

[0020] Working Principle: In the succinic acid production process, the material is added to the mixing tank, and the variable speed motor is started. The controller controls the variable speed motor to run according to the preset speed change curve, and the stirring rod 10 drives the mixing plate 20 to rotate. As the rotation speed changes, the centrifugal force on the mixing plate 20 also changes. When the centrifugal force is greater than the elastic force of the return spring 70, the sealing plate 50 slides outward along the limiting rod 60, the through hole 40 opens, and the material enters the interior of the mixing plate 20 through the guide cylinder 80 and is sprayed out from the through hole 40 to mix with the material in the mixing tank. Because the centrifugal force on the mixing plate 20 is different at different positions, the opening time and degree are also different, thereby realizing that the material enters the mixing area from different heights at different stages, improving the mixing uniformity. The inclined setting of the mixing plate 20, the inclined design of the through hole 40, and the application of the guide cylinder 80 together enhance the axial flow and turbulence effect of the material, further improving the mixing efficiency.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
