Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering and pharmaceutical manufacturing, in particular to a liquid reaction jet stirring device. Background Art

[0002] In the chemical and pharmaceutical process flows, the yield and reaction rate determine the output per unit time. Since the yield can generally only be increased by optimizing the process flow, therefore, how to use mechanical devices to increase the reaction rate of raw materials has become the main research direction of those skilled in the art.

[0003] A jet mixing nozzle with stirring blades is disclosed in the Chinese utility model patent with the publication number CN215471035U. It includes a first nozzle and a second nozzle. The second nozzle is arranged outside the first nozzle. An inhalation chamber is formed between the first nozzle and the second nozzle. A suction port is arranged on the second nozzle. A spiral blade is arranged in the inhalation chamber. The second nozzle includes a second jet port. The spiral blade is located at the second jet port. The first nozzle and the second nozzle are connected by a bearing. A plurality of stirring blades are arranged on the outer wall of the second nozzle.

[0004] The above patent includes a spiral blade to stir the fluid, which theoretically can make the reaction more uniform and rapid. However, since its energy transfer is divided into two levels of the first nozzle and the second nozzle, there is a large energy loss after passing through the two-stage nozzle, which easily leads to a reduction in the rotation speed of the spiral blade, resulting in a low stirring efficiency. Therefore, improvement is needed. Summary of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a liquid reaction jet stirring device, which uses the reaction force generated by the ejection of the reaction liquid to drive the jet stirrer to rotate for stirring. The stirring effect is good, which is beneficial to improving the reaction rate.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A liquid reaction jet stirring device includes a storage tank, a feeding system and a jet stirrer connected in sequence. The feeding system includes a delivery pump and a delivery pipe connected to each other;

[0008] The jet agitator includes a jet cylinder and a stirring paddle; a hollow liquid infusion channel is provided inside the jet cylinder; the inner diameter of the liquid infusion channel gradually decreases along the flow direction; the stirring paddles are circumferentially arrayed and installed in the middle of the outer side of the jet cylinder; two or more jet holes are provided at the lower part of the jet cylinder, and the jet holes are circumferentially arrayed on the jet cylinder and communicate with the liquid infusion channel; a plurality of evenly distributed flow guiding strips are arranged on the inner wall of the middle part of the jet cylinder, and the lower ends of the flow guiding strips extend to the upper side of the jet holes; the end of the delivery pipe is connected with a mounting collar, and a mounting shaft and rollers are arranged in the mounting collar. A connecting joint is arranged in the jet agitator, the connecting joint is sleeved outside the mounting collar, and a mounting hole matching with the roller is arranged in the connecting joint.

[0009] Further, locking nuts and locking pins for fixing the rollers are arranged at both ends of the mounting shaft; rolling bearings are arranged in the rollers.

Specific embodiments

[0024] The following further describes the present utility model in detail with reference to the drawings and specific embodiments:

[0025] Referring to Figures 1-4 as shown, a liquid reaction jet mixing device includes a storage tank 4, a feeding system, and a jet mixer 1 connected in sequence. The feeding system includes a delivery pump 2 and a delivery pipe 3 connected to each other; the jet mixer 1 includes a jet cylinder 11 and a stirring paddle 13; a hollow infusion channel 16 is provided inside the jet cylinder 11; the inner diameter of the infusion channel 16 gradually decreases along the flow direction; the stirring paddle 13 is circumferentially and arrayedly installed in the middle of the outer side of the jet cylinder 11; two or more jet holes 12 are provided at the lower part of the jet cylinder 11. In the embodiment, the jet holes 12 include three to eight, and the outlet of each jet hole 12 is inclined downward. The guide strip 14 is spirally arranged on the inner wall above the jet holes 12, and the number of the guide strips 14 is the same as the number of the jet holes 12; the jet holes 12 are circumferentially and arrayedly distributed on the jet cylinder 11 and communicate with the infusion channel 16; a plurality of uniformly distributed guide strips 14 are provided on the inner wall of the middle part of the jet cylinder 11, and the lower ends of the guide strips 14 extend to the upper side of the jet holes 12; the end of the delivery pipe 3 is connected with a mounting collar 31 to facilitate strengthening the connection. The mounting collar 31 is provided with a mounting shaft 32 and a roller 33. A connection joint 15 is provided in the jet mixer 1. The connection joint 15 is sleeved outside the mounting collar 31, and a mounting hole 151 matching the roller 33 is provided in the connection joint 15.

[0026] Both ends of the installation shaft 32 are provided with a locking nut 34 and a locking pin 35 for fixing the roller 33, ensuring that the jet agitator 1 will not become loose during rotation; a rolling bearing is provided in the roller 33; a gap is left between the inner wall of the connection joint 15 and the outer wall of the installation collar 31 to reduce friction. A detachable auxiliary support frame (not shown in the schematic diagram) is provided at the upper end of the installation collar 31, and the auxiliary support frame is detachably and fixedly connected to the reaction vessel; after fixation, it prevents the end of the delivery pipe 3, the installation collar 31, and the jet agitator 1 from shaking during rotation.

[0027] A heating device 41 is installed inside the storage tank 4.

[0028] The working principle of the present utility model is as follows:

[0029] Pour a certain amount of reaction solution A into the storage tank 4 and turn on the heating device 41. After the solution A is heated up, turn on the delivery pump 2, and the solution A is delivered to the jet agitator 1 through the delivery pipe 3 and then conveyed in the liquid delivery channel 16. Since the inner diameter of the liquid delivery channel 16 gradually decreases along the flow direction, it pressurizes the solution A, which is beneficial for the solution A to be sprayed farther from the spray holes 12, increasing its contact area with the reaction solution B, which is beneficial for improving the reaction efficiency of the two, and thus better improving the reaction rate.

[0030] The jet agitator 1 is immersed in the reaction solution B. When the solution A flows inside the jet agitator 1, the flow direction is guided by the guide strips 14 and the spray holes 12, and the solution A will be ejected from the jet agitator 1 in a vortex. The jet cylinder 11 receives the reaction force of its ejection, and the agitator connection joint 15 thereon starts to rotate relative to the installation collar 31; and drives the stirring paddle 13 to start rotating accordingly, so that the jet agitator 1 can stir the reaction solution B, accelerating the reaction between the solution A and the reaction solution B. The heating device 41 is used to heat the solution A, and the reaction solution B is also heated up due to the addition of the heated solution A, which can further improve the reaction rate of the two.

[0031] The above description is only the specific implementation manner of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the description and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
