Technical Field

[0001] The utility model relates to a high-efficiency and high-viscosity stirring evaporation concentrator used in the chemical industry. Background Art

[0002] The stirring and evaporation of high-viscosity materials has always been a difficult problem in industrial applications. Due to the high viscosity of the material, it is easy to produce excessive viscosity during the stirring process, making it difficult for the stirring mechanism to stir the material and stirring it unevenly. At the same time, as the stirring and evaporation process progresses, the viscosity of the material will gradually increase, which further increases the difficulty of stirring. Utility Model Content

[0005] The shell is arranged horizontally, with a material inlet at the center of the top and a material outlet at the center of the bottom;

[0006] The stirring assembly is arranged at one end of the shell through a large flange device. The stirring assembly is connected to one end of the main shaft. The main shaft is bridged in the shell. Several groups of high-viscosity material plowshare groups are arranged on the outside of the main shaft along the axial direction of the shell. The other end of the main shaft is connected to the rotary joint. The rotary joint is provided with a heat medium inlet and a heat medium outlet. The main shaft is a hollow structure with an internal heating reflux pipe inside, and the internal heating reflux pipe is connected to the heat medium outlet.

[0008] Furthermore, for any two adjacent groups of high-viscosity material plowshares, the angle between the setting directions of the sequential plowshares is 30°, and at least four groups of high-viscosity material plowshares are arranged on the main shaft, so that the plowshare setting directions cover 360°.

[0009] Furthermore, the plow consists of a cutter head and a connecting arm. The cutter head is a shovel-shaped structure composed of two knife-shaped pieces and a triangular piece. The cutter head is connected to the main shaft through the connecting arm.

[0010] Furthermore, the stirring assembly includes a motor, a reducer, a reducer section bracket and a motor side mechanical seal.

[0015] The utility model is a high-efficiency and high-viscosity stirring evaporation concentrator. Through the built-in internal heating circulation pipeline, the material is continuously heated from the inside during the stirring process to ensure that the material is always in a viscous and easy-to-stir temperature range; the multi-angle plow blade is set to ensure that the material is fully stirred within the shell, eliminating the stirring dead corners in the shell to avoid the adhesion of viscous materials, and the introduction of protective gas can ensure the stirring atmosphere of the material to prevent oxidation.

[0018] In order to better understand the technical solution of the utility model, the following is a detailed description through specific embodiments:

[0019] See also Figure 1 The utility model discloses a high-efficiency and high-viscosity stirring evaporation concentrator, which comprises a shell 7 and a stirring assembly.

[0020] The housing 7 is arranged horizontally, and a material inlet is arranged at the center of the top thereof, and a material outlet is arranged at the center of the bottom thereof. The material inlet is connected to a material feed flange 10, and the material outlet is connected to a material discharge ball valve 9.

[0021] The stirring assembly is arranged at one end of the housing through a large flange device 5. The stirring assembly comprises a motor 1, a reducer 2, a reducer section bracket 3 and a motor side mechanical seal 4.

[0022] The main shaft 8 is connected to the shell 7, one end of the main shaft 8 is connected to the stirring assembly, and a number of high-viscosity material plowshare groups are arranged at equal intervals along the axial direction of the shell 7 on the outside of the main shaft 8. Each group of high-viscosity material plowshare groups consists of 3 plowshares 6, and the angle between the setting directions of each plowshare 6 is 120°. For any two adjacent groups of high-viscosity material plowshare groups, the angle between the setting directions of the sequential plowshares is 30°. At least 4 groups of high-viscosity material plowshare groups are arranged on the main shaft, so that the plowshare setting direction covers 360°. The plowshare consists of a cutter head and a connecting arm. Please refer to Figure 2 The blade head is composed of two blade-shaped pieces 61 and one triangular piece 62 to form a shovel-shaped structure, and the blade head is connected to the main shaft through a connecting arm. When the stirring assembly drives the main shaft and the plowshare to rotate, the shovel-shaped blade head scoops up the viscous material from the inside of the shell to the high point inside the shell and then drops it down to achieve stirring of the viscous material. The 360° plowshare allows materials in all positions and directions inside the shell to be scooped up by the plowshare, without any dead angles.

[0023] The other end of the main shaft 8 is connected to the rotary joint 16, and the rotary joint 16 is connected to the shell 7 through the mechanical seal 15 on the rotary joint side and the frame 14 at the rotary joint. The rotary joint 16 is provided with a heat medium inlet 161 and a heat medium outlet 162. The main shaft 8 is a hollow structure, and an internal heating reflux pipe 13 is provided inside, and the internal heating reflux pipe 13 is connected to the heat medium outlet 162. Through this heat circulation structure, the shell 7 can dissipate heat from the inside, continuously heat the material in the shell 7, ensure that the material is always in a temperature range where the viscosity is easy to stir, and evaporate and concentrate the material.

[0024] In another embodiment, a jacket 12 is provided outside the shell 7, and a heat medium inlet and a heat medium outlet are provided on the jacket, so that the shell can heat the material in the shell from both the outside and the inside, thereby improving the heating effect.

[0025] In another embodiment, a nitrogen inlet 71 is provided on the housing 7. The introduction of protective gas can prevent oxidation during heating and stirring.

[0026] In another embodiment, a sampling port 17 is provided at the lower end of one side of the housing 7. By sampling the material in the housing, the real-time state of the material can be grasped to adjust the mixing process of the material and determine the completion time of the mixing.

[0027] The housing 7 is supported by a supporting device 11 .
