Description

TECHNICAL FIELD

[0001] The present application relates to the field of chemical equipment, in particular to a reaction kettle facilitating switching of impeller types. BACKGROUND

[0002] The reaction kettle is an important reaction container widely used in the field of chemical industry, mainly used for realizing material mixing required by specific processes.

[0003] In the related art, the reaction kettle is composed of a kettle body, a kettle cover and an agitator. The agitator includes an agitator shaft, an agitator head and a rotary drive. The agitator shaft is rotatably installed on the kettle cover. The rotary drive is connected to the top end of the agitator shaft and used to drive the agitator shaft to rotate. The agitator head is installed at the bottom end of the agitator shaft and specifically includes a shaft sleeve and a plurality of stirring blades. The stirring blades are welded to the outer periphery of the shaft sleeve. The shaft sleeve is fixed on the agitator shaft by a plurality of fastening bolts.

[0004] In actual production, different materials require different stirring requirements. In order to meet the stirring requirements of the materials, it is usually necessary to switch the agitator head with different blade types to ensure that the subsequent agitator can fully mix the materials in the reaction kettle.

[0005] In the related art, when switching the blade type of the agitator head, a person usually enters the kettle body through the manhole on the kettle cover and then disassembles and replaces the agitator head at the end of the agitator shaft. Since the operation space on the inner wall of the kettle body is relatively limited and the inner environment of the kettle body is relatively closed, the overall operation is inconvenient. Therefore, there is room for improvement. SUMMARY

[0006] In order to facilitate the switching operation of the agitator head with different blade types of the reaction kettle, the present application provides a reaction kettle facilitating switching of impeller types.

[0007] The reaction kettle facilitating switching of impeller types provided by the present application adopts the following technical solution:

[0010] The sliding drive assembly is drivingly connected to the kettle body and used to drive the kettle body to slide in the horizontal direction.

[0011] The lifting driving assembly is connected with the kettle cover for driving the kettle cover to vertically slide.

[0012] By adopting the above technical scheme, when the stirring head of the stirrer is switched, the lifting assembly drives the cover to drive the stirrer to move upwards until the stirrer is separated from the kettle body, then the sliding driving member drives the kettle body to slide horizontally until the cover is staggered with the kettle body, and finally the lifting driving assembly drives the cover to drive the stirrer to move downwards, so that the maintenance personnel disassemble and replace the stirring head at the tail end of the stirring shaft, so as to complete the switching operation of the stirring head with different blade types. When the stirring head is replaced, the operator unscrews the fastening bolt of the connecting shaft sleeve from the stirring shaft, slides the shaft sleeve of the stirring head to be replaced out of the stirring shaft, sleeves the shaft sleeve of the new stirring head into the tail end of the stirring shaft, and re-fixes the shaft sleeve of the new stirring head on the stirring shaft by the fastening bolt. Compared with the operation mode of the conventional reaction kettle for switching the stirring head with different blade types of the stirrer, manual operation in the kettle body is not required, so that the switching operation of the stirring head with different blade types of the reaction kettle stirrer is more simple and convenient.

[0013] Preferably, the sliding driving assembly comprises an electric screw rod module, the electric screw rod module comprises a sliding table, and the kettle body is connected to the sliding table; the lifting driving assembly comprises a lifting oil cylinder arranged vertically, and the piston rod of the lifting oil cylinder is connected with the kettle cover.

[0014] By adopting the above technical scheme, the kettle body is driven to move horizontally by the electric screw rod module and the kettle cover is driven to move vertically by the lifting oil cylinder, which is beneficial to the smooth movement of the kettle body and the kettle cover.

[0016] By adopting the technical scheme, the auxiliary dismounting mechanism is moved below the stirring shaft of the stirrer while the kettle body and the kettle cover are driven to be staggered by the electric screw rod module; when the stirring head at the tail end of the stirrer is dismounted and mounted, the supporting ring is driven to move upward by the first lifting driving element until the supporting ring abuts against the bottom end of the shaft sleeve of the stirring head to be replaced, so that the shaft sleeve is temporarily supported and limited; after the fastening bolts at the shaft sleeve of the stirring head are screwed out, the supporting ring is driven to move downward by the first lifting driving element, so that the shaft sleeve can slide out of the tail end of the stirring shaft, which is beneficial to the stable disengagement of the stirring head from the stirring shaft and limits the situation that the stirring head directly slides off the stirring shaft and falls to the sliding table after the fastening bolts around the shaft sleeve of the stirring head are screwed out; when a new stirring head is installed, the new stirring head can be placed on the supporting ring, and the supporting ring is driven to move upward by the first lifting driving element to drive the new stirring head, so as to assist the new stirring head sleeve to be sleeved into the tail end of the stirring shaft.

[0018] By adopting the technical scheme, through the setting of the clamping assembly, after the supporting ring abuts against the bottom end of the shaft sleeve of the stirring head to be dismounted and mounted by the first lifting driving element, the corresponding clamping block is driven to abut against the outer periphery of the shaft sleeve by the first sliding driving element, and a plurality of clamping blocks are used to clamp and limit the stirring head to be replaced, so as to limit the situation that the stirring head to be replaced is slid off the supporting ring during the subsequent downward movement of the supporting ring; on the other hand, when a new stirring head is installed, the shaft sleeve of the new stirring head can be placed between a plurality of clamping blocks, and the corresponding clamping block is driven to abut against the outer periphery of the shaft sleeve of the new stirring head by the first sliding driving element, so as to quickly position the shaft sleeve of the new stirring head, so that the shaft sleeve of the new stirring head is more easily sleeved into the tail end of the stirring shaft.

[0019] Preferably, the first sliding driving element comprises a first sliding cylinder, the upper surface of the supporting ring is provided with a mounting groove corresponding to the first sliding cylinder, the first sliding cylinder is embedded in the mounting groove, and the piston rod of the first sliding cylinder is connected with the corresponding clamping block.

[0020] By adopting the technical scheme, the first sliding cylinder is embedded in the mounting groove, so as to be accommodated in the supporting ring, thereby limiting the first sliding cylinder from protruding above the upper surface of the supporting ring, and further limiting the situation that the first sliding cylinder interferes with the stirring blades of the stirring head when the supporting ring is driven to move upward by the first lifting driving element.

[0021] Preferably, the sliding table is further provided with a clamping shaft assembly for clamping the stirring shaft, the clamping shaft assembly comprises two clamping shaft portions located at opposite sides of the outer periphery of the supporting ring and arranged towards the axial direction of the supporting ring, and each of the clamping shaft portions comprises a clamping shaft frame provided with a clamping shaft block and a second sliding drive, and the second sliding drive is in driving connection with the clamping shaft block for driving the clamping shaft block to move towards or away from the axial direction of the supporting ring.

[0023] Preferably, the side of each clamping shaft block towards the axial direction of the supporting ring is provided with a semicircular arc-shaped groove for embedding the stirring shaft.

[0024] By adopting the above technical scheme, the contact area between the clamping shaft block and the stirring shaft is increased by the semicircular arc-shaped groove, which is beneficial to better clamp and limit the stirring shaft by the two clamping shaft blocks.

[0025] Preferably, the sliding table is further provided with a second lifting drive corresponding to the clamping shaft frame, the second lifting drive is in driving connection with the clamping shaft frame for driving the clamping shaft frame to vertically ascend and descend.

[0026] By adopting the above technical scheme, during the stirring process of the reactor agitator, part of the material is likely to penetrate into the connection between the shaft sleeve and the stirring shaft, affecting the subsequent installation of the new stirring head. Through the arrangement of the second lifting drive, when the first lifting drive drives the supporting ring to slide the shaft sleeve of the stirring head to be replaced downward out of the stirring shaft, the second lifting drive drives the corresponding clamping shaft frame to move the clamping shaft block downward, and the clamping shaft block removes the sundries adhered to the installation position of the stirring head on the stirring shaft, thereby realizing the cleaning of the stirring shaft, which is beneficial to make the shaft sleeve of the new stirring head more easily sleeved into the stirring shaft.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0029] 2. By setting the auxiliary disassembly mechanism on the sliding table of the electric screw rod module, when disassembling and replacing the stirring head, the first lifting driving element drives the support ring to move upwards until the support ring abuts against the bottom end of the shaft sleeve of the stirring head to be replaced, thereby supporting and limiting the stirring head to be replaced, so that after the fastening bolt at the shaft sleeve of the stirring head is unscrewed, the stirring head directly falls from the stirring shaft to the sliding table.

[0030] 3. By setting the shaft clamping assembly, when disassembling and replacing the stirring head at the tail end of the stirring shaft, the second sliding driving element of the two shaft clamping parts drives the corresponding clamping block to abut against the outer periphery of the stirring shaft to support and limit the stirring shaft, thereby reducing the stress deformation of the stirring shaft during subsequent disassembly and replacement of the stirring head.

DETAILED DESCRIPTION

[0039] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0040] This application discloses a reaction vessel that facilitates switching of stirrer blade types, see embodiments thereof. Figure 1 and Figure 2 The reactor includes a reactor body 1, a sliding drive assembly, and a lifting drive assembly. The reactor body 1 includes a vessel body 11, a vessel cover 12, and a stirrer 13. The vessel cover 12 is supported at the top opening of the vessel body 11 to seal the top opening. The stirrer 13 includes a stirring shaft 131, a rotary drive component 132, and a stirring head 133. The rotary drive component 132 is mounted on the vessel cover 12 and is drivenly connected to the top end of the stirring shaft 131 to drive the stirring shaft 131 to rotate. The stirring head 133 is mounted at the tail end of the stirring shaft 131. The sliding drive assembly is drivenly connected to the vessel body 11 to drive the vessel body 11 to slide horizontally. The lifting drive assembly is drivenly connected to the vessel cover 12 to drive the vessel cover 12 to rise and fall vertically.

[0041] The stirring head 133 includes a bushing 1331 and several stirring blades 1332 welded and fixed to the outer periphery of the bushing 1331. The bushing 1331 is sleeved on the tail end of the stirring shaft 131, and the outer periphery of the bushing 1331 is connected to the stirring shaft 131 by several fastening bolts.

[0042] Reference Figure 1 and Figure 3 When switching between different blade types of stirring heads 133 of the stirrer 13, the lifting drive assembly first drives the lid 12 to move the stirrer 13 upward away from the vessel body 11, and then the sliding drive assembly drives the vessel body 11 to slide horizontally until the vessel body 11 and the lid 12 are horizontally misaligned. Then the lifting drive assembly drives the lid 12 to move the stirrer 13 downward so that the stirring head 133 located at the end of the stirring shaft 131 can be disassembled and replaced by the operator.

[0043] The sliding drive assembly includes a horizontally arranged electric screw module 2, which includes a slide table 21. The outer periphery of the vessel body 11 is connected to the slide table 21 via several legs 111, thus enabling the sliding drive assembly to be driven and connected to the vessel body 11. The lifting drive assembly includes two vertically arranged lifting cylinders 3, which are located on opposite sides of the electric screw module 2. The piston rods of both lifting cylinders 3 are connected to the outer periphery of the vessel cover 12 via connecting blocks, thus enabling the lifting drive assembly to be driven and connected to the vessel cover 12.

[0044] Reference Figure 4 and Figure 5The auxiliary disassembling and assembling mechanism 4 is arranged on both ends of the sliding table 21 of the electric screw rod module 2. The auxiliary disassembling and assembling mechanism 4 comprises a supporting ring 41 and a first lifting driving member. The inner periphery contour of the supporting ring 41 is matched with the outer periphery contour of the stirring shaft 131, so that the supporting ring 41 is penetrated by the tail end of the stirring shaft 131. The bottom of the supporting ring 41 is connected with a support 410. The first lifting driving member comprises a first lifting cylinder 42 vertically arranged on the sliding table 21. The first lifting cylinder 42 is located at the bottom of the supporting ring 41. The piston rod of the first lifting cylinder 42 is connected with the support 410, so that the first lifting driving member is drivingly connected with the supporting ring 41. The supporting ring 41 can be vertically lifted by the first lifting cylinder 42.

[0045] With reference to Figure 5 and Figure 6 The supporting ring 41 is further provided with a clamping assembly. The clamping assembly comprises a plurality of clamping portions 43 which are uniformly distributed around the axial direction of the supporting ring 41. The clamping portion 43 comprises a clamping block 431 and a first sliding driving member. The clamping block 431 is protruded on the upper surface of the supporting ring 41. The first sliding driving member is drivingly connected with the clamping block 431, so as to drive the clamping block 431 to move towards the direction close to or away from the axial direction of the supporting ring 41.

[0046] Specifically, the first sliding driving member comprises a first sliding cylinder 432. The supporting ring 41 is provided with a plurality of installation grooves 411 corresponding to the first sliding cylinder 432. The first sliding cylinder 432 is embeddedly installed in the corresponding installation groove 411. The first sliding cylinder 432 is arranged towards the axial direction of the supporting ring 41. The piston rod of the first sliding cylinder 432 is connected with the corresponding clamping block 431.

[0047] By arranging the auxiliary disassembling and assembling mechanism 4, the sliding table 21 and the kettle body 11 driven by the electric screw rod module 2 are staggered with the kettle cover 12. At the same time, the auxiliary disassembling and assembling mechanism 4 is located below the stirrer 13 of the kettle cover 12. When the stirring head 133 located on the stirring shaft 131 is disassembled and replaced, the supporting ring 41 is driven upwards by the first lifting cylinder 42 until the supporting ring 41 abuts below the shaft sleeve 1331 of the stirring head 133 to be replaced, so as to temporarily limit the stirring head 133 to be replaced. After the fastening bolt connecting the shaft sleeve 1331 of the stirring head 133 and the stirring shaft 131 is screwed out of the shaft sleeve 1331 by the operator, the supporting ring 41 and the stirring head 133 to be replaced are driven downwards by the first lifting cylinder 42 until the stirring head 133 to be replaced is separated from the stirring shaft 131, so as to complete the disassembly of the stirring head 133. This is conducive to stably separating the stirring head 133 to be replaced from the stirring shaft 131, and reduces the situation that the stirring head 133 directly falls off from the stirring shaft 131 to the sliding table 21 after the fastening bolt of the shaft sleeve 1331 is screwed out.

[0048] Meanwhile, when the new stirring head 133 is replaced subsequently, the shaft sleeve 1331 of the new stirring head 133 can be placed between the clamping blocks 431 on the support ring 41, and then the corresponding clamping block 431 is driven to abut against the outer periphery of the shaft sleeve 1331 of the new stirring head 133 by the first sliding cylinder 432, so that the shaft sleeve 1331 at the new stirring head 133 is opposite to the stirring shaft 131, and the new stirring head 133 is quickly positioned. Then the support ring 41 drives the new stirring head 133 to move upward by the first lifting cylinder 42, until the shaft sleeve 1331 of the new stirring head 133 is sleeved on the stirring shaft 131. The support ring 41 cooperates with the clamping assembly to sleeve the new stirring head 133 on the tail end of the stirring shaft 131 and temporarily limit it, so that the operator fixes the shaft sleeve 1331 of the new stirring head 133 on the stirring shaft 131 by the fastening bolt.

[0049] By embedding the first sliding cylinder 432 in the corresponding installation groove 411 on the support ring 41, it is beneficial to limit the interference between the first sliding cylinder 432 and the stirring blade 1332 of the stirring head 133 during the subsequent upward movement of the support ring 41.

[0050] Referring to Figure 5 and Figure 6 , the slide table 21 is also provided with a shaft clamping assembly for clamping the stirring shaft 131. The shaft clamping assembly includes two shaft clamping parts 5, which are respectively located on the opposite sides of the outer periphery of the support ring 41 and are higher than the support ring 41. The shaft clamping part 5 is arranged in the axial direction of the support ring 41. The shaft clamping part 5 includes a shaft clamping frame 51, and a shaft clamping block 52 is arranged on the shaft clamping frame 51. A semicircular arc-shaped groove 521 is formed on the side of the shaft clamping block 52 in the axial direction of the support ring 41, and the semicircular arc-shaped groove 521 is used for embedding the stirring shaft 131. The shaft clamping frame 51 is also provided with a second sliding driving member for driving the shaft clamping block 52 to move in the axial direction close to or away from the stirring shaft 131. Specifically, the second sliding driving member includes a second sliding cylinder 53, which is arranged in the axial direction of the support ring 41 and the piston rod of the second sliding cylinder 53 is connected with the shaft clamping block 52, so that the second sliding driving member is drivingly connected with the shaft clamping block 52.

[0051] By arranging the shaft clamping assembly, when the stirring head 133 located at the tail end of the stirring shaft 131 is removed subsequently, the corresponding shaft clamping block 52 is driven by the second sliding cylinder 53 of the two shaft clamping parts 5 to move in the axial direction close to the support ring 41, until the semicircular arc-shaped groove 521 at the shaft clamping block 52 abuts against the outer periphery of the stirring shaft 131. The two shaft clamping blocks 52 cooperate to support and limit the stirring shaft 131, which is beneficial to limit the stress deformation of the stirring shaft 131 during the subsequent disassembly and assembly of the stirring head 133 located at the tail end of the stirring shaft 131.

[0052] The sliding table 21 corresponds to two clamping shaft parts 5 supports 410 and is provided with two second lifting driving members. The second lifting driving member comprises a second lifting cylinder 6 vertically arranged on the sliding table 21. The second lifting cylinder 6 is located below the clamping shaft support 51 corresponding to the clamping shaft part 5. The second lifting cylinder 6 piston rod is connected with the bottom of the clamping shaft support 51. Subsequently, when the first lifting cylinder 42 drives the support ring 41 to drive the stirring head 133 to move downward, the two second lifting cylinders 6 are simultaneously driven to drive the clamping shaft support 51 to drive the clamping shaft block 52 to move downward, so as to use the two clamping shaft blocks 52 to scrape off the sundries adhered to the shaft sleeve 1331 of the stirring shaft 131 from the stirring shaft 131, thereby facilitating the subsequent sleeving of the shaft sleeve 1331 of the new stirring head 133 to the stirring shaft 131.

[0053] The implementation principle of the embodiment of the present application is that when the stirring head 133 of different blade types of the stirrer 13 is switched, the two lifting cylinders 3 are first driven to drive the kettle cover 12 to drive the stirrer 13 to separate upward from the kettle body 11, then the electric screw rod module 2 is driven to drive the kettle body 11 to slide along the horizontal direction to be staggered with the kettle cover 12, and the auxiliary dismounting mechanism 4 is located below the kettle cover 12. The two lifting cylinders 3 are driven to drive the kettle cover 12 to drive the stirrer 13 to be close to the auxiliary dismounting mechanism 4, and then the auxiliary dismounting mechanism 4 is used to complete the dismounting and replacing of the stirring head 133 at the tail end of the stirring shaft 131 by manual work, so as to realize the switching of the stirring head 133 of different blade types of the stirrer 13. The operator does not need to enter the inside of the reaction kettle to work, so that the switching operation of the stirring head 133 of different blade types of the stirrer 13 of the reaction kettle is more simple and convenient.

[0054] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
