Description

Technical Field

[0001] This utility model relates to a coil-type stirring vessel, belonging to the technical field of chemical stirring vessels. Background Technology

[0002] Stirred tanks are core reaction equipment in chemical, pharmaceutical, and new material preparation processes, widely used for mixing multiphase materials. Conventional stirred tanks typically have a single built-in impeller, and the inner wall of the tank either lacks flow-dissipating components or has fixed flow-dissipating plates welded on. This type of structure has the following shortcomings in practical applications:

[0003] First, for stirred tanks without baffles, the mixing effect of a single impeller is mainly concentrated in the central area of ​​the tank. It relies primarily on the inner layer of material to move the outer layer. Due to liquid resistance, material near the inner wall of the tank is difficult to agitate sufficiently, resulting in poor mixing and prolonged mixing time. Second, for stirred tanks with baffles, the fixed welded baffle structure cannot be adjusted once formed. It is impossible to replace the baffles with suitable ones for materials of different viscosities, resulting in poor adaptability and limiting the equipment's effectiveness under various process conditions. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a coil-type mixing vessel equipped with replaceable baffles and various mixing components to improve the mixing efficiency of materials and enhance the mixing effect and process adaptability of materials.

[0005] The present invention provides a coil-type stirring vessel, comprising: a driving component on the vessel body; an agitation assembly that can be driven by the driving component inside the vessel body; a coil wrapped around the outer wall of the vessel body; and baffles on the inner wall of the vessel body.

[0006] The agitation assembly includes: a drive shaft connected to the drive unit, a stirring frame and an auger fitted on the drive shaft, and the stirring frame can cover the periphery of the auger.

[0007] Furthermore, the vessel body includes: a vessel body and a vessel lid that are fitted together; a defoaming plate is press-fitted between the vessel body and the vessel lid.

[0008] The coil can be installed on the outer wall of the vessel.

[0009] Furthermore, the inner wall of the vessel body is provided with several slots, and the baffle strips can be fitted into the slots.

[0013] The stirring blades extend in a spiral shape along the axial direction of the support frame.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] The utility model discloses a double stirring assembly combining the inner layer auger with the outer layer stirring frame. The auger is responsible for the axial turning of the center area and the material at the bottom of the kettle, and the stirring frame is responsible for the wall scraping and the mixing of the peripheral material. The two cooperate to form a three-dimensional and omnidirectional circulating flow in the kettle, solve the problem of the center whirl and the slow flow of the wall material caused by the traditional single stirring paddle, ensure the uniformity of the material mixing, and improve the stirring efficiency. The spoiler strip of the kettle body inner wall adopts a pluggable modular design. Users can conveniently and quickly replace the spoiler strips with different shapes or different flow dividing holes according to the viscosity, reaction rate and other process requirements of different materials.

[0031] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0032] like Figures 1 to 5 As shown, the present invention provides a coil-type stirring vessel, comprising: a driving component 4 on the vessel body, an agitation assembly that can be driven by the driving component 4 inside the vessel body; a coil 2 wrapped around the outer wall of the vessel body; and a turbulence strip 7 on the inner wall of the vessel body.

[0033] In this embodiment, the coil 2 is a semi-circular tube, which forms a cavity between itself and the outer wall of the vessel body 1. Heating liquid or cooling liquid can be introduced into the coil 2 to heat or cool the vessel body 1. Conventionally, the inlet and outlet of the coil 2 can be connected to an external heat exchange system. In this embodiment, the heat exchange system is a heat exchange pump station.

[0034] The agitation assembly includes: a drive shaft 5 connected to the drive component 4, a stirring frame 8 and an auger 9 fitted on the drive shaft 5, the stirring frame 8 being able to cover the periphery of the auger 9, such as... Figure 1 As shown. In this embodiment, the driving component 4 is a motor.

[0035] Specifically, the vessel body includes: a vessel body 1 and a vessel lid 3 that are configured to fit together; a defoaming plate 6 is press-fitted between the vessel body 1 and the vessel lid 3; and a coil 2 can be installed on the outer wall of the vessel body 1.

[0036] The defoaming board 6 is grid-shaped; the defoaming board 6 is provided with a defoaming net; the defoaming net can be bound to the grid of the defoaming board 6.

[0037] In this embodiment, both the coil 2 and the vessel body 1 are made of stainless steel.

[0038] Specifically, the inner wall of the vessel body 1 is provided with several slots 101, and the baffle strip 7 can be fitted into the slots 101.

[0039] Specifically, the deflector 7 includes: a base 701 that can be snapped into the slot 101, a deflector 702 on the base 701, and a plurality of diversion holes 703 on the deflector 702.

[0040] In this embodiment, the spoiler 702 is plate-shaped; preferably, the spoiler 702 can also be tubular. The spoiler 702 can form an obstacle to the material to form a turbulent flow, and the flow dividing hole 703 can further divide the fluid material to make it mix sufficiently.

[0041] Specifically, the stirring frame 8 comprises a support frame 802, the support frame 802 is provided with an adapter frame 801 connectable to the transmission shaft 5, and the support frame 802 is provided with a plurality of stirring blades 803.

[0042] Specifically, the stirring blades 803 extend spirally along the axial direction of the support frame 802. Preferably, the rotation direction of the stirring blades 803 can be opposite to the rotation direction of the auger 9; the bottom end of the auger 9 can be lowered to the bottom of the kettle to stir the material at the bottom of the kettle; further, in the axial direction of the kettle body, the auger 9 can drive the inner layer material close to the center of the kettle body to turn over, and the stirring frame 8 can drive the outer layer material close to the inner wall of the kettle body to turn over, and the two work together to realize the axial turning over of the material in the kettle body, as shown in Figure 5 .

[0043] The specific use principle of the utility model is as follows:

[0044] Firstly, according to the process requirement, the suitable spoiler strip 7 is selected, the base 701 of the spoiler strip 7 is inserted into the pre-set slot 101 in the inner wall of the kettle body 1, and the arrangement of the spoiler structure is completed.

[0045] When operating, the driving part 4 is started, and the auger 9 and the stirring frame 8 are simultaneously driven to rotate through the transmission shaft 5. The auger 9 located at the center is mainly responsible for the axial conveying and turning over of the material, and can lift the material at the bottom of the kettle to the upper part or press the material at the upper part to the bottom of the kettle, forming a strong central flow. At the same time, the stirring frame 8 and the spiral stirring blades 803 thereof covered outside the auger 9 mainly act on the area close to the inner wall of the kettle body, and the outer layer material is scraped up and mixed axially and radially. Preferably, when the rotation directions of the auger 9 and the stirring frame 8 are opposite, strong shearing action and circulating flow are generated between the auger 9 and the stirring frame 8, so that a radial, axial three-dimensional composite flow is formed in the kettle body.

[0046] In the process of high-speed rotating flow of the material, the tangential flow is hindered by the spoiler strip 7 fixed on the kettle wall, so that the flow direction is forced to change, the "spinning" phenomenon caused by single rotation is prevented, and strong turbulent flow is formed. The flow dividing hole 703 on the spoiler 702 can further divide and disturb the fluid, and the effect of contact and collision between different materials is enhanced.

[0047] In addition, the grid-shaped defoaming plate 6 press-fitted between the kettle cover 3 and the kettle body 1 can effectively break the bubbles that can be generated in the stirring process, so that the reaction can be carried out stably. The coil pipe 2 on the outer wall of the kettle body 1 can pass in the heat exchange medium, so as to provide uniform and timely heat exchange for the high-efficiency mixed material.

[0048] It is particularly pointed out that: in the description of the utility model, the direction or position relation indicated by the terms "front", "back", "upper", "lower", "left", "right" and the like is the direction or position relation based on the direction or position relation shown in the drawing, and is only for the convenience of describing the utility model, and does not require the utility model to be necessarily constructed and operated in a particular direction, therefore, it cannot be understood as the limitation of the utility model.
