TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical equipment, in particular to a reaction kettle suitable for blocky and crystalline materials. BACKGROUND

[0002] In the daily operation process of the chemical field, due to the production process requirements of various products, a reaction kettle is usually used to stir and mix materials.

[0003] In the related art, the stirrer inside the reaction kettle usually adopts a traditional structure such as a flat paddle and an anchor paddle; when processing blocky materials (such as caked powder and unsolved solids) and crystalline materials, since the above-mentioned types of materials often have strong cohesiveness or hardness, the shear capacity of the traditional stirrer structure is limited, and it is difficult to generate enough shear force to break and disperse the materials during actual stirring, resulting in poor overall stirring effect and difficulty in effectively dispersing blocky or crystalline materials. In addition, blocky materials and crystalline materials usually have high density, and once they cannot be effectively mixed with the reaction medium at the initial stage of stirring, they are prone to deposit at the bottom of the kettle, further affecting the stirring effect of blocky or crystalline materials. Therefore, there is room for improvement. SUMMARY

[0004] In order to make the stirring structure better disperse blocky or crystalline materials and improve the dispersion effect of blocky or crystalline materials at the bottom of the reaction kettle.

[0005] The present application provides a reaction kettle suitable for blocky and crystalline materials, which adopts the following technical scheme: A reaction kettle suitable for blocky and crystalline materials, comprising a kettle body, a kettle cover and a stirring structure; The stirring structure comprises a stirring shaft, a rotary driving member and a stirring assembly; the stirring shaft is rotationally connected to the kettle cover and extends into the inner cavity of the kettle body; the rotary driving member is used to drive the stirring shaft to rotate; the stirring assembly comprises a support sleeve coaxially sleeved on the outer periphery of the stirring shaft, and a first stirring part and a second stirring part are distributed above and below the support sleeve; The first stirring part comprises a plurality of first stirring blades protruding from the outer periphery of the support sleeve, and each first stirring blade is vertically provided with a plurality of shear cutter plates; The second stirring part comprises a plurality of second stirring blades protruding from the outer periphery of the support sleeve, and each second stirring blade extends helically upward away from the support sleeve; A limiting sleeve is coaxially arranged at the bottom of the kettle body, and the bottom end of the stirring shaft is rotationally connected to the limiting sleeve through a connecting piece to radially limit the stirring shaft; The connecting piece comprises a connecting sleeve coaxially sleeved on the bottom end of the stirring shaft, and a sliding bearing is fixed on the inner periphery of the limiting sleeve, and the connecting sleeve rotates and penetrates the sliding bearing; A plurality of through holes are formed on the outer periphery of the limiting sleeve, and a plurality of through holes are formed on the outer periphery of the sliding bearing; a plurality of spiral grooves are uniformly formed on the outer periphery of the connecting sleeve, and the two ends of the spiral grooves extend to the two ends of the connecting sleeve, and the two ends of the spiral grooves are provided with openings.

[0006] By adopting the above technical scheme, when the rotary driving member drives the stirring shaft to rotate, the inventor thinks of using the shearing force of the shearing blade on the first stirring blade to first cut and scatter the blocky or crystalline material according to the characteristics of the blocky or crystalline material having strong cohesiveness or hardness, and at the same time, the spiral second stirring blade drives the material to turn upward, and the second stirring blade generates disturbance to the surrounding material fluid during rotation, forming local turbulent flow, and the two work together to realize the crushing, scattering and sufficient stirring of the blocky or crystalline material. If there is no shearing blade, the cohesively blocky or crystalline material cannot be effectively cut and scattered, and the material is difficult to be dispersed uniformly by conventional stirring, therefore, the specific cooperation of the shearing blade and the spiral second stirring blade is indispensable. Compared with the traditional stirring structure adopting flat paddle and anchor paddle, greater shear force can be generated to realize the crushing, scattering and sufficient stirring of the blocky or crystalline material, and the blocky or crystalline material is effectively limited from depositing at the bottom of the kettle body due to gravity, so that the blocky or crystalline material can be better mixed with the reaction medium. On the other hand, by rotatingly connecting the bottom end of the stirring shaft to the limiting sleeve at the bottom of the kettle body through the connecting piece, the limiting sleeve limits the stirring shaft in the radial direction, effectively improving the shaking or deviation of the stirring shaft due to the stress on the first stirring part and the second stirring part when stirring the blocky or crystalline material, and at the same time, the through holes on the limiting ring cooperate with the spiral grooves of the connecting sleeve to shear the material at the bottom of the material stirring kettle, which is beneficial to further improve the shearing and stirring effect of the material at the bottom of the material stirring kettle. At the same time, the circulating material exchanges heat with the limiting sleeve and the connecting sleeve to timely take away the heat generated by the relative rotation of the two, limit the relative rotation of the limiting sleeve and the connecting sleeve to generate high temperature, and prevent some temperature-sensitive materials from crystallizing and accumulating between the limiting sleeve and the connecting sleeve, which affects the normal rotation of the stirring shaft.

[0007] Preferably, the shearing blade is triangular in cross section; the shearing blades are uniformly distributed along the first stirring blade; and the shearing blades located at the end of the first stirring blade away from the supporting sleeve are arranged close to the inner periphery of the kettle body.

[0008] By adopting the technical scheme, the cross section of the shearing blade is triangular, the shearing blade forms a pointed end structure, which is beneficial to the shearing blade to cut into the blocky or crystalline material and cut it open and scatter; meanwhile, the spiral second stirring blade can generate disturbance to the surrounding material fluid and form local turbulent flow when rotating, and the two work together to realize the crushing, scattering and uniform stirring of the blocky or crystalline material.

[0009] Preferably, the first stirring blades are arranged in a staggered manner with the second stirring blades.

[0010] By adopting the technical scheme, the coverage of the shearing effect of the shearing blade and the second stirring blade can be ensured, and the shearing blind area in the kettle body can be reduced.

[0011] Preferably, the first stirring blades correspond to the second stirring blades one by one, and the second stirring blades are connected to the corresponding first stirring blades at the ends away from the stirring shaft.

[0012] By adopting the technical scheme, the end of the second stirring blade is connected to the corresponding first stirring blade, which is beneficial to improving the connection integrity and structural strength of the first stirring part and the second stirring part, facilitating the two to better crush and shear the material while limiting the deformation of the first stirring part and the second stirring part under stress during stirring.

[0013] Preferably, the bottom ends of the shearing blades extend and are arranged close to the bottom of the inner cavity of the kettle body.

[0014] By adopting the technical scheme, the stirring range of the first stirring part can extend to the bottom of the kettle body, so as to better shear and disperse the material at the bottom of the kettle body, and the dispersion effect of the material at the bottom of the kettle body is improved.

[0015] Preferably, the bottom end of the limiting sleeve is spaced from the bottom of the inner cavity of the kettle body; the bottom of the kettle body is provided with a discharge port, the discharge port is located at the bottom of the limiting sleeve and is arranged opposite to the limiting sleeve; and the bottom of the kettle body is further connected with a discharge pipe, which is in communication with the discharge port.

[0016] By adopting the technical scheme, the subsequent material in the kettle body can be normally discharged through the discharge pipe, avoiding the situation that the limiting sleeve interferes with the discharge of the material through the discharge port.

[0017] Preferably, the top and bottom ends of the connecting sleeve extend out of the two ends of the limiting sleeve.

[0018] By adopting the above technical solution, when the subsequent stirring shaft drives the connecting sleeve to rotate, the connecting sleeve can stir the material located at the top and bottom of the limiting sleeve through the spiral groove, which is beneficial to improve the uniformity of stirring of the material at the bottom of the vessel.

[0019] Preferably, the support sleeve is fixed to the stirring shaft by a keyway structure, and the stirring shaft is fitted with two limiting rings corresponding to the support sleeve, with the two limiting rings respectively abutting the top and bottom ends of the support sleeve.

[0020] By adopting the above technical solution, the keyway structure is used to achieve a stable connection between the support sleeve and the stirring shaft, which is beneficial for the first and second stirring parts to rotate synchronously with the stirring shaft. By setting two limiting rings, the support sleeve is axially limited, which helps to restrict the axial movement of the support sleeve during the rotation of the stirring shaft, thereby facilitating the stirring shaft to better drive the first and second stirring parts to stir the materials.

[0021] Preferably, a connecting flange is connected to the outer periphery of the top end of the discharge pipe, and the connecting flange is fixed to the bottom of the reactor body by bolts; a plurality of connecting rods are provided on the outer periphery of the limiting sleeve, and the ends of the connecting rods away from the limiting sleeve are all connected to the connecting flange.

[0022] By adopting the above technical solution, a stable connection between the discharge pipe and the reactor body can be achieved. When the limiting sleeve and sliding bearing need to be disassembled and replaced, the limiting sleeve and sliding bearing can be removed from the reactor body by removing the discharge pipe.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the synergistic action of the first stirring blade and the second stirring blade, during operation, the shearing blade on the first stirring blade is used to cut and break up the blocky or crystalline material. At the same time, the spiral second stirring blade causes the material to turn upward. When rotating, it can disturb the surrounding material fluid and form local turbulence. The two work together to break up, break up and fully mix the blocky or crystalline material.

[0024] 2. By setting a connecting sleeve at the bottom of the stirring shaft and rotatably connecting the connecting sleeve to the limiting sleeve at the bottom of the vessel body through a sliding bearing, the bottom of the stirring shaft can be radially limited. This helps to limit the force on the stirring components at the stirring shaft, which could cause deformation and displacement at the bottom of the stirring shaft, and ensure that the first stirring part and the second stirring part at the stirring structure can maintain a stable movement path.

[0025] 3. By opening a through hole and a spiral groove on the limiting sleeve and the outer periphery of the connecting sleeve, when the connecting sleeve is rotated by the subsequent stirring shaft, the material can be circulated into the spiral groove through the through hole, and discharged through the spiral groove. The circulating material can timely take away the heat generated when the connecting sleeve rotates, and is beneficial to auxiliary shear dispersion of the material. BRIEF DESCRIPTION OF DRAWINGS

[0041] With reference to Figure 3 and Figure 4 In the embodiment, the support sleeve 331 is coaxially fixed on the stirring shaft 31 through the key groove structure, so that the stirring assembly 33 and the stirring shaft 31 are stably connected, and the stirring assembly 33 is convenient to disassemble and assemble on the stirring shaft 31. The stirring shaft 31 is coaxially sleeved with two limiting rings 311 corresponding to the support sleeve 331, the limiting rings 311 are fixed on the stirring shaft 31 by bolts, and the two limiting rings 311 abut against the top and bottom ends of the support sleeve 331, respectively.

[0047] The implementation principle of the embodiment of the present application is: when the blocky or crystalline material is stirred in the reaction kettle, the stirring shaft 31 is driven to rotate by the rotary driving member 32, the blocky or crystalline material is first cut open and scattered by the first stirring blade 3321 of the first stirring part 332 cooperating with the shear cutter plate 3322; then the blocky or crystalline material is driven to overturn upward by the second stirring blade 3331 of the second stirring part 333, and the second stirring blade 3331 can generate disturbance to the surrounding material fluid when rotating, forming local turbulent flow. The first stirring part 332 and the second stirring part 333 cooperate to realize the crushing, scattering and sufficient stirring of the blocky or crystalline material, effectively improving the stirring effect of the blocky or crystalline material.

[0048] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
