Description

Technical Field

[0001] The present application relates to the technical field of stirring equipment, and in particular to a corrugated jacket of stirring equipment. Background Art

[0002] Mixing equipment is an important device used to mix different materials and make them react fully. It is widely used in chemical, pharmaceutical, bioengineering and food processing industries. In the production process of these industries, the requirements for the mixing uniformity and reaction conditions of materials are extremely strict, and the performance of the mixing equipment directly affects the quality and output of the final product. Among them, the jacket of the mixing equipment is a key component to achieve the temperature control function. It can not only ensure that the materials react at a suitable temperature, but also effectively prevent problems such as material deterioration or incomplete reaction caused by temperature fluctuations, thereby ensuring the stability and safety of the production process.

[0003] The jacket styles of existing mixing equipment are diverse, mainly including integral jackets, coil jackets, honeycomb jackets, etc. The integral jacket is a container with a slightly larger diameter put on the outer peripheral side of the mixing equipment (such as a mixing tank). This jacket has a simple structure and is easy to manufacture. However, due to the relatively thin structure of the integral jacket, it is easy to deform under high temperature or high pressure environment. The coil jacket achieves temperature control by arranging coils on the outer peripheral side of the mixing equipment, but since the coils cannot fully surround the mixing equipment, the overall temperature control effect is not good, especially in large mixing equipment. Although the honeycomb jacket has a good temperature control effect, the manufacturing process is complicated and the technical requirements for the manufacturing personnel are high. Therefore, there is an urgent need for a mixing equipment jacket with high structural strength and good temperature control effect to meet the high standards of modern industrial production. Summary of the invention

[0004] In order to improve the structural strength and temperature control effect of the jacket, the present application provides a corrugated jacket of a stirring equipment.

[0005] The corrugated jacket of a stirring device provided in the present application adopts the following technical solution:

[0006] A corrugated jacket of a stirring device comprises a plurality of first prefabricated plates, wherein the plurality of first prefabricated plates are combined to form a ring and surround the outer peripheral side of the stirring device; each of the first prefabricated plates is wavy and forms a plurality of first wave peaks and a plurality of first wave valleys, and the surfaces of the first prefabricated plates located at the first wave valleys are attached to the outer peripheral wall of the stirring device, and a temperature control channel for temperature control is formed between the first wave peaks of the first prefabricated plates and the outer peripheral wall of the stirring device, and the two ends of the temperature control channel are extended along the central axis of the stirring device.

[0007] By adopting the above technical solution, the first precast slab is wavy. After a plurality of first precast slabs are combined to surround the outer peripheral side of the mixing device, a plurality of temperature control channels are formed on the outer peripheral side of the mixing device. This enables the introduction of a heat exchange medium into the temperature control channels according to actual needs, thereby effectively controlling the temperature inside the mixing device. At the same time, the plurality of first precast slabs completely surround the mixing device, and the first precast slab is set to be wavy, which improves the structural strength of the first precast slab and makes it not easy to deform under thermal expansion and contraction or external forces, greatly enhancing the structural strength and temperature control effect of the jacket.

[0008] Optionally, a plurality of welding holes for welding are formed on the surface of the first precast slab located at the first trough, and the plurality of welding holes are arranged at intervals along the length direction of the temperature control channel; the side walls of two adjacent first precast slabs that are close to each other are in contact with each other and combined to form the first trough.

[0009] By adopting the above technical solution, through the arrangement of the welding holes, the first precast slab is welded and fixed to the outer peripheral wall of the mixing device. In addition, the part where two adjacent first precast slabs are in contact with each other is the first trough. After welding, the two adjacent first precast slabs are connected into one body, so that a plurality of first precast slabs completely surround the mixing device, improving the temperature control effect.

[0010] Optionally, a second precast slab is installed on each first precast slab. The second precast slab is wavy and forms a plurality of second peaks and a plurality of second troughs; the plurality of first peaks of the first precast slab and the plurality of second peaks of the second precast slab are arranged in an alternating manner. The second precast slab divides the temperature control channel of the first precast slab into a first heat preservation area and two temperature control areas. The first heat preservation area is located between the first peak of the first precast slab and the second trough of the second precast slab. The two temperature control areas are distributed on both sides of the first heat preservation area, and the temperature control areas are located between the first trough of the first precast slab and the second trough of the second precast slab; a second heat preservation area is formed by enclosing between the first trough of the first precast slab and the second peak of the second precast slab; the temperature control areas are used for introducing a heat exchange medium, and the first heat preservation area and the second heat preservation area are both used for introducing a heat preservation gas.

[0011] By adopting the above technical solution, the addition of the second precast slab further divides the temperature control channel of the first precast slab into a first heat preservation area and two temperature control areas. The temperature control areas can more precisely control the temperature change inside the mixing device, while the first heat preservation area and the second heat preservation area can effectively maintain the constant temperature state of the device, reduce heat loss, and improve the temperature control efficiency and stability. On the other hand, the wavy design of the first precast slab and the second precast slab and their alternating arrangement enhance the overall structural strength of the jacket, prevent deformation caused by thermal expansion and contraction or external forces, and improve the service life and reliability of the jacket.

[0012] Optionally, the distance between the first peak and the adjacent first valley of the first precast slab is the first wavelength segment, and the distance between the second peak and the adjacent second valley of the second precast slab is the second wavelength segment; the first wavelength segment and the second wavelength segment are arranged in a crosswise manner, a first avoidance groove for avoiding the second wavelength segment is formed in the top wall of the first wavelength segment, and a second avoidance groove for avoiding the first wavelength segment is formed in the bottom wall of the second wavelength segment; a tightening assembly is arranged between the first wavelength segment and the second wavelength segment, and the tightening assembly is used for tightening the first wavelength segment and the second wavelength segment to seal the first avoidance groove and the second avoidance groove.

[0013] By adopting the above technical solution, the crosswise arrangement between the first wavelength segment and the second wavelength segment enables the first precast slab and the second precast slab to be closely matched, improving the stability and strength of the overall structure. At the same time, the design of the first avoidance groove and the second avoidance groove ensures that there is no interference at the intersection of the first wavelength segment and the second wavelength segment, guaranteeing the overall smoothness of the jacket. The use of the tightening assembly further enhances the connection stability between the first wavelength segment and the second wavelength segment, effectively preventing medium leakage and improving the sealing performance of the jacket.

[0014] Optionally, a plurality of tightening areas are formed at the intersection of the first wavelength segment and the second wavelength segment, the tightening assembly includes tightening rods, tightening discs and tightening members, the number of the tightening rods is correspondingly arranged with the number of the tightening areas, and each tightening rod passes through the corresponding tightening area; two tightening discs are provided and symmetrically distributed at both ends of the tightening rod, and each tightening disc is provided with a plurality of sliding grooves for the tightening rod to pass through; the tightening member is arranged on the tightening disc to drive all the tightening rods to synchronously displace towards the center of the tightening disc.

[0015] By adopting the above technical solution, the tightening rods pass through their respective corresponding tightening areas, and after the two ends of the tightening rods pass through the sliding grooves of the two tightening discs respectively, the tightening member drives all the tightening rods to synchronously displace towards the center of the tightening disc, so that the plurality of tightening rods clamp the intersection of the first wavelength segment and the second wavelength segment, connecting the first precast slab and the second precast slab into a whole and improving the overall sealing performance.

[0016] Optionally, the tightening member includes a rotating ring and tightening blocks, the rotating ring is rotatably connected to the tightening disc and is in threaded connection with the tightening disc, the tightening blocks are arranged on the inner peripheral wall of the rotating ring, and a plurality of tightening blocks are arranged around the central axis of the rotating ring, the plurality of tightening blocks are correspondingly arranged with the plurality of tightening rods, and each tightening block has a guiding surface for pushing the tightening rod to displace towards the center of the tightening disc.

[0017] By adopting the above-mentioned technical solution, the design enables all the tightening blocks to rotate synchronously when the rotating ring is driven to rotate. Each tightening block pushes the corresponding tightening rod through its own guide surface. The cooperation of multiple tightening blocks causes all the tightening rods to move synchronously toward the center of the tightening disk to clamp the intersection of the first wavelength band and the second wavelength band, thereby improving the stability and sealing of the overall structure.

[0018] Optionally, the side walls of the two tightening disks that are close to each other are provided with multiple limiting ridges, and the multiple limiting ridges are arranged corresponding to the multiple tightening areas. The limiting ridges are used to be embedded in the corresponding tightening areas, and one end of the limiting ridge abuts the surface of the first wavelength band, and the other end abuts the surface of the second wavelength band.

[0019] By adopting the above-mentioned technical solution and setting the limiting convex strip, the tightening disk is placed at the intersection of the first wavelength band and the second wavelength band to form a limit, which can maintain the position of the tightening disk and reduce the possibility of rotation or displacement of the tightening disk during the operation of driving the tightening rod toward the center of the tightening disk, thereby improving the convenience of operation.

[0020] Optionally, the outer wall of the mixing equipment is provided with two closed rings, and the first prefabricated plate and the second prefabricated plate are both located between the two closed rings; the side walls of the closed ring are respectively provided with a first embedding groove for embedding the first prefabricated plate and a second embedding groove for embedding the second prefabricated plate, and sealing gaskets are both provided in the first embedding groove and the second embedding groove; the closed ring is provided with a third avoidance groove for avoiding the tightening disk, and the tightening disk is provided with a tightening member, and the tightening member is used to force the closed ring to press against the first prefabricated plate and the second prefabricated plate.

[0021] By adopting the above technical solution, the first embedding groove and the second embedding groove of the closed ring are used for embedding the first prefabricated plate and the second prefabricated plate, and the sealing between the first prefabricated plate and the closed ring and between the second prefabricated plate and the closed ring is ensured by the sealing gasket to prevent leakage of the heat exchange medium. The fastening member on the tightening disk can effectively force the closed ring to fit tightly against the first prefabricated plate and the second prefabricated plate, further enhancing the stability and sealing performance of the entire structure, thereby ensuring the temperature control effect of the jacket.

[0022] Optionally, the clamping member comprises a clamping ring, which is rotatably connected to the tightening disk and threadedly connected to the tightening disk, and the clamping ring has a clamping portion, the outer diameter of which is larger than the outer diameter of the tightening disk for clamping the closed ring.

[0023] By adopting the above-mentioned technical solution, the clamping ring is rotated so that the clamping part of the clamping ring is pressed against the closed ring, thereby forcing the first prefabricated panel to be firmly embedded in the first embedding groove and press against the sealing gasket in the first embedding groove, and forcing the second prefabricated panel to be firmly embedded in the second embedding groove and press against the sealing gasket in the second embedding groove, thereby improving the sealing between the first prefabricated panel and the closed ring, and between the second prefabricated panel and the closed ring.

[0024] Optionally, a limiting ring is provided on the end face of the clamping ring close to the rotating ring, and a compression spring is provided between the limiting ring and the clamping ring. When the clamping ring is pressed against the closed ring, the limiting ring abuts against the rotating ring, and the compression spring is deformed and has elastic force.

[0025] By adopting the above-mentioned technical solution, the compression spring between the limiting ring and the clamping ring can generate elastic force when the clamping ring is pressed against the closed ring. The elastic force reacts on the clamping ring and the rotating ring respectively, thereby increasing the thread friction between the clamping ring and the tightening disk, and between the rotating ring and the tightening disk, so that the rotating ring and the clamping ring are not easy to rotate freely, thereby improving the stability of the overall structure.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The first prefabricated plate is set to be wavy, and after multiple first prefabricated plates are combined to surround the outer peripheral side of the stirring device, multiple temperature control channels are formed on the outer peripheral side of the stirring device. This allows heat exchange medium to be introduced into the temperature control channel according to actual needs, thereby effectively controlling the temperature in the stirring device. At the same time, multiple first prefabricated plates fully surround the stirring device, and the first prefabricated plates are set to be wavy, which improves the structural strength of the first prefabricated plates, making it less likely to deform under thermal expansion and contraction or external forces, greatly improving the structural strength and temperature control effect of the jacket;

[0028] 2. Through the setting of the second prefabricated plate, the addition of the second prefabricated plate enables the temperature control channel of the first prefabricated plate to be further divided into a first insulation zone and two temperature control zones. The temperature control zone can more accurately control the temperature changes in the mixing equipment, while the first insulation zone and the second insulation zone can effectively maintain the constant temperature state of the equipment, reduce heat loss, and improve temperature control efficiency and stability. On the other hand, the wavy design of the first prefabricated plate and the second prefabricated plate and their staggered arrangement enhance the overall structural strength of the jacket, prevent deformation due to thermal expansion and contraction or external forces, and improve the service life and reliability of the jacket;

[0029] 3. Through the setting of the tightening member, the first embedding groove and the second embedding groove of the closed ring are for the first precast slab and the second precast slab to be embedded, and the sealing gasket is used to ensure the sealing performance between the first precast slab and the closed ring, and between the second precast slab and the closed ring, preventing the leakage of the heat exchange medium. The tightening member on the tightening disc can effectively force the closed ring to closely fit the first precast slab and the second precast slab, further enhancing the stability and sealing performance of the entire structure, thus ensuring the temperature control effect of the jacket.

[0043] The following further elaborates on this application Figure 1 - with reference to the attached Figure 12 drawings to provide a more detailed description.

[0044] Embodiment 1

[0045] The embodiment of this application discloses a corrugated jacket for a stirring device.

[0046] Referring to Figure 1 , Figure 2 , a corrugated jacket for a stirring device includes a plurality of first prefabricated plates 1. The plurality of first prefabricated plates 1 enclose to form a ring for surrounding the outer peripheral wall of the stirring device 7. In this embodiment, each first prefabricated plate 1 is wavy and forms a plurality of first wave crests 11 and a plurality of first wave troughs 12. The first prefabricated plate 1 is formed into a wavy shape by a pressing die.

[0047] The surface of the first prefabricated plate 1 located at the first wave trough 12 fits against the outer peripheral wall of the stirring device 7, and a temperature control channel 2 is formed between the surface of the first prefabricated plate 1 located at the first wave crest 11 and the outer peripheral wall of the stirring device 7. In this embodiment, the stirring device 7 is a cylindrical and vertically arranged stirring tank, and both ends of the temperature control channel 2 extend along the central axis of the stirring device 7. The plurality of first wave crests 11 of the first prefabricated plate 1 form a plurality of temperature control channels 2. The temperature control channel 2 is used to introduce a heat exchange medium to control the temperature of the stirring device 7. The heat exchange medium depends on actual needs. For example, when the stirring device 7 needs to be heated, the heat exchange medium can be steam or a heating liquid, etc. When the stirring device 7 needs to be cooled, the heat exchange medium can be cooling water or cold air, etc.

[0048] Referring to Figure 2 , Figure 3, on the surface of the first precast slab 1 located in the first trough 12, a plurality of welding holes 13 are provided. The plurality of welding holes 13 are arranged at intervals along the length direction of the temperature control channel 2. Each welding hole 13 penetrates through the first precast slab 1 for welding, so that the first precast slab 1 can be welded and fixed on the outer peripheral wall of the stirring device 7. It should be noted that the side walls of two adjacent first precast slabs 1 close to each other abut against each other and form the first trough 12 together. During welding, the gap between two adjacent first precast slabs 1 also needs to be welded to ensure the overall sealing performance.

[0049] Refer to Figure 1 , two sealing rings 5 are fixedly installed on the outer peripheral wall of the stirring device 7. The two sealing rings 5 are arranged at intervals along the central axis of the stirring device 7. All the first precast slabs 1 are located between the two sealing rings 5. The two sealing rings 5 are used to block the upper and lower ports of all the temperature control channels 2. In this embodiment, the inner peripheral wall of the sealing ring 5 and the outer peripheral wall of the stirring device 7, and between the sealing ring 5 and the first precast slab 1 are fixedly connected by welding.

[0050] Refer to Figure 1 , Figure 4 , temperature control cavities 54 are provided in both of the two sealing rings 5. The side wall of the sealing ring 5 close to the first precast slab 1 is provided with a plurality of first communication holes 541 communicating with the temperature control cavity 54. The plurality of first communication holes 541 are arranged corresponding to the plurality of temperature control channels 2. The temperature control channels 2 are communicated with the temperature control cavity 54 through the first communication holes 541. It should be noted that in this embodiment, the sealing ring 5 located at the bottom of the first precast slab 1 is connected with an input pipe (not shown in the figure), and the outlet end of the input pipe is communicated with the temperature control cavity 54 of the corresponding sealing ring 5 for inputting heat exchange medium; the sealing ring 5 located at the top of the first precast slab 1 is connected with an output pipe (not shown in the figure), and the inlet end of the output pipe is communicated with the temperature control cavity 54 of the corresponding sealing ring 5 for outputting heat exchange medium.

[0051] The implementation principle of Embodiment 1 of the present application is as follows: The first precast slab 1 is in a wavy shape. After a plurality of first precast slabs 1 are combined to surround the outer periphery of the stirring device 7, a plurality of temperature control channels 2 are formed on the outer periphery of the stirring device 7. This enables heat exchange medium to be introduced into the temperature control channels 2 according to actual needs, thereby effectively controlling the temperature inside the stirring device 7. At the same time, the plurality of first precast slabs 1 form a complete enclosure around the stirring device 7, and the first precast slab 1 is set in a wavy shape, which improves the structural strength of the first precast slab 1, making it not easy to deform under thermal expansion and contraction or external force, and greatly enhancing the structural strength and temperature control effect of the jacket.

[0052] Embodiment 2

[0053] The embodiment of the present application discloses a corrugated jacket of a stirring device.

[0054] Refer to Figure 5 , Figure 6, the corrugated jacket of a stirring device disclosed in an embodiment of the present application is different from that in Embodiment 1 in that:

[0055] In this embodiment, each first prefabricated plate 1 is provided with a second prefabricated plate 3. The second prefabricated plate 3 is wavy and forms a plurality of second wave crests 31 and second wave troughs 32. The plurality of first wave crests 11 of the first prefabricated plate 1 and the plurality of second wave crests 31 of the second prefabricated plate 3 are arranged staggeredly (that is, the plurality of first wave troughs 12 of the first prefabricated plate 1 and the plurality of second wave troughs 32 of the second prefabricated plate 3 are also arranged staggeredly); the surface of the second prefabricated plate 3 at the second wave trough 32 abuts against the surface of the stirring device 7, the first wave crest 11 of the first prefabricated plate 1 faces the second wave trough 32 of the second prefabricated plate 3, and the first wave trough 12 of the first prefabricated plate 1 faces the second wave crest 31 of the second prefabricated plate 3.

[0056] Refer to Figure 5 , Figure 6 , for the convenience of description, hereinafter, the section between the first wave crest 11 and the adjacent first wave trough 12 of the first prefabricated plate 1 is defined as the first wavelength section 14, and the section between the second wave crest 31 and the adjacent second wave trough 32 of the second prefabricated plate 3 is defined as the second wavelength section 33; the first wavelength section 14 and the second wavelength section 33 are arranged crosswise. The top wall of the first wavelength section 14 is provided with a first avoidance groove 141 for avoiding the second wavelength section 33, and the bottom wall of the second wavelength section 33 is provided with a second avoidance groove 331 for avoiding the first wavelength section 14. The second prefabricated plate 3 is inserted into the first prefabricated plate 1 from top to bottom through the avoidance cooperation of the first avoidance groove 141 and the second avoidance groove 331.

[0057] Refer to Figure 5 , the second prefabricated plate 3 divides the temperature control channel 2 of the first prefabricated plate 1 into a first heat preservation area 21 and two temperature control areas 22. The first heat preservation area 21 is located between the first wave crest 11 of the first prefabricated plate 1 and the second wave trough 32 of the second prefabricated plate 3. The two temperature control areas 22 are distributed on both sides of the first heat preservation area 21, and the temperature control area 22 is located between the first wave trough 12 of the first prefabricated plate 1 and the second wave trough 32 of the second prefabricated plate 3; a second heat preservation area 23 is formed by enclosing between the first wave trough 12 of the first prefabricated plate 1 and the second wave crest 31 of the second prefabricated plate 3.

[0058] In this embodiment, the temperature control area 22 is used for introducing a heat exchange medium, and both the first heat preservation area 21 and the second heat preservation area 23 are used for introducing a heat preservation gas. The heat preservation gas can be carbon dioxide to slow down the outward transfer of heat in the temperature control area 22, which is applicable to the application occasions of heating or heat preservation for the stirring device 7.

[0059] Refer to Figure 5 , Figure 7 , Figure 8, a tightening assembly 4 is arranged between the first wavelength segment 14 and the corresponding second wavelength segment 33. The tightening assembly 4 is used to tighten the first wavelength segment 14 and the second wavelength segment 33 to seal the first avoidance groove 141 and the second avoidance groove 331; four tightening zones 24 are formed at the intersection of the first wavelength segment 14 and the second wavelength segment 33. The tightening assembly 4 includes tightening rods 41, tightening discs 42 and tightening members. The number of tightening rods 41 corresponds to the number of tightening zones 24. Each tightening rod 41 passes through the corresponding tightening zone 24. The length direction of the tightening rod 41 is consistent with the length direction of the temperature control channel 2. A sealing sleeve (not shown in the figure) is sleeved on the outer peripheral wall of the tightening rod 41, and the sealing sleeve is made of rubber.

[0060] Refer to Figure 8 , Figure 9 , two tightening discs 42 are arranged and symmetrically distributed at both ends of the tightening rod 41. The tightening discs 42 are in a disc shape. The central axis of the tightening disc 42 is located at the central position of the intersection of the first wavelength segment 14 and the second wavelength segment 33. A plurality of limiting ridges 422 are fixedly installed on the side walls of the two tightening discs 42 close to each other. The plurality of limiting ridges 422 correspond to the plurality of tightening zones 24. Each limiting ridge 422 is used to be embedded into the corresponding tightening zone 24, and one end of the limiting ridge 422 abuts against the surface of the first wavelength segment 14, and the other end abuts against the surface of the second wavelength segment 33. Each tightening disc 42 is provided with a plurality of sliding grooves 421 for the tightening rods 41 to pass through. The plurality of sliding grooves 421 correspond to the plurality of tightening rods 41. Both ends of each sliding groove 421 extend along the radial direction of the tightening disc 42, and the plurality of sliding grooves 421 communicate with each other.

[0061] Refer to Figure 7 , Figure 8 , the tightening member is arranged on the tightening disc 42 to drive all the tightening rods 41 to synchronously displace towards the center of the tightening disc 42. The tightening member includes a rotating ring 43 and a tightening block 44. The rotating ring 43 is installed in the tightening disc 42 and is coaxially arranged with the tightening disc 42. In this embodiment, the outer peripheral wall of the rotating ring 43 is in threaded connection with the inner peripheral wall of the tightening disc 42 (the thread between the rotating ring 43 and the tightening disc 42 is not shown in the figure) so that the rotating ring 43 can rotate around its own central axis.

[0062] Refer to Figure 7 , Figure 8, the tightening blocks 44 are fixedly installed on the inner peripheral wall of the rotating ring 43, and a plurality of them are arranged around the central axis of the rotating ring 43. The plurality of tightening blocks 44 are arranged corresponding to the plurality of tightening rods 41. Each tightening block 44 has a guiding surface 441 for pushing the tightening rod 41 to displace towards the center of the tightening disc 42. It should be noted that since the first wavelength band 14 and the second wavelength band 33 are not vertically crossed (that is, the distances from each tightening rod 41 to the center position of the tightening disc 42 are different), when the tightening blocks 44 are manufactured, the sizes of the plurality of tightening blocks 44 are set to be different, so as to ensure that the guiding surfaces 441 of the tightening blocks 44 can all abut against the corresponding tightening rods 41. Furthermore, when the rotating ring 43 rotates, all the tightening rods 41 can be displaced synchronously towards the center position of the tightening disc 42.

[0063] Referring to Figure 8 、 Figure 10 , two docking holes 431 are opened on the side wall of the rotating ring 43 away from the first prefabricated plate 1. The rotating ring 43 is detachably installed with a driving rod 8 for driving the rotation of the rotating ring 43. Two docking rods 81 are fixedly installed on the peripheral wall of the driving rod 8. The two docking rods 81 are respectively used to insert into the two docking holes 431 of the rotating ring 43, and the driving rod 8 can drive the rotating ring 43 to rotate around its own central axis.

[0064] Referring to Figure 7 , in this embodiment, a plurality of third avoidance grooves 53 for avoiding the tightening disc 42 are opened on the side wall of the closed ring 5 close to the first prefabricated plate 1. The third avoidance grooves 53 provide an avoidance space for the installation of the tightening disc 42, and a sealing ring 531 is embedded on the inner wall of the third avoidance groove 53; a heat preservation cavity 55 is opened in the closed ring 5. The heat preservation cavity 55 is located outside the temperature control cavity 54. A plurality of second communication holes 551 communicating with the heat preservation cavity 55 are opened on the side wall of the closed ring 5 close to the first prefabricated plate 1. The number of the first heat preservation areas 21 plus the number of the second heat preservation areas 23 is equal to the number of the second communication holes 551. All the first heat preservation areas 21 and all the second heat preservation areas 23 are communicated with the heat preservation cavity 55 through their respective corresponding second communication holes 551; the closed ring 5 is connected with an air delivery pipe (not shown in the figure) for delivering air to the heat preservation cavity 55, and the air delivery pipe is used for delivering heat preservation gas.

[0065] It should be noted that in the installation sequence of the jacket in this embodiment, first, the first prefabricated plate 1 is installed, then the second prefabricated plate 3 is installed, and finally the closed ring 5 is installed; during the installation of the second prefabricated plate 3, after the tightening block 44 tightens the tightening rod 41, sealant can be filled into the tightening disc 42 to block the sliding groove 421, so as to further improve the overall sealing performance.

[0066] The implementation principle of Embodiment 2 of this application is as follows: The addition of the second prefabricated plate 3 further divides the temperature control channel 2 of the first prefabricated plate 1 into a first heat preservation area 21 and two temperature control areas 22. The temperature control area 22 can control the temperature change in the stirring device 7, while the first heat preservation area 21 and the second heat preservation area 23 can effectively maintain the constant temperature state of the device, reduce heat loss, and improve the temperature control efficiency and stability. On the other hand, the wavy design of the first prefabricated plate 1 and the second prefabricated plate 3 and their staggered arrangement enhance the overall structural strength of the jacket, prevent deformation caused by thermal expansion and contraction or external forces, and improve the service life and reliability of the jacket.

[0067] After the second prefabricated plate 3 is inserted into the first prefabricated plate 1, the tightening assembly 4 is installed. The tightening rods 41 are inserted through their respective corresponding tightening areas 24, and after both ends of the tightening rods 41 pass through the sliding grooves 421 of the two tightening discs 42 respectively, all the tightening rods 41 are driven by the tightening member to synchronously displace towards the center of the tightening disc 42, so that the multiple tightening rods 41 clamp at the intersection of the first wavelength segment 14 and the second wavelength segment 33, connect the first prefabricated plate 1 and the second prefabricated plate 3 into a whole, and improve the overall sealing performance.

[0068] Embodiment 3

[0069] Embodiment of this application discloses a corrugated jacket for a stirring device.

[0070] Refer to Figure 11 、 Figure 12 The difference between the corrugated jacket for a stirring device disclosed in the embodiment of this application and Embodiment 2 lies in:

[0071] In this embodiment, the third avoidance groove 53 is set as a through groove penetrating the closed ring 5, and the side walls of the closed ring 5 are respectively provided with a first embedding groove 51 for embedding the first prefabricated plate 1 and a second embedding groove 52 for embedding the second prefabricated plate 3. Sealing gaskets (not shown in the figure) are fixedly installed in both the first embedding groove 51 and the second embedding groove 52; the tightening disc 42 is provided with a pressing member for forcing the closed ring 5 to press against the first prefabricated plate 1 and the second prefabricated plate 3.

[0072] Refer to Figure 11, the pressing member is provided as a pressing ring 6. The pressing ring 6 is installed inside the tightening disc 42 and coaxially arranged with the tightening disc 42. In this embodiment, there is a threaded connection between the outer peripheral wall of the pressing ring 6 and the inner peripheral wall of the tightening disc 42 (the thread between the pressing ring 6 and the tightening disc 42 is not shown in the figure), so that the pressing ring 6 can rotate around its own central axis; the pressing ring 6 has a pressing portion 61, and the outer diameter of the pressing portion 61 is larger than the outer diameter of the tightening disc 42 for pressing against the side wall of the closing ring 5 away from the first precast slab 1; the driving mode of the pressing ring 6 is the same as that of the rotating ring 43, that is, the pressing ring 6 also needs to be provided with a docking hole 431 (not shown in the figure) for the docking rod 81 of the driving rod 8 to be inserted.

[0073] Refer to Figure 11 , a limiting ring 62 is slidably installed on the end face of the pressing ring 6 close to the rotating ring 43. The limiting ring 62 is coaxially arranged with the pressing ring 6 and can displace along the central axis of the pressing ring 6; a compression spring 63 is installed between the limiting ring 62 and the pressing ring 6. One end of the compression spring 63 is fixedly connected to the pressing ring 6, and the other end is fixedly connected to the limiting ring 62. When the pressing ring 6 presses against the closing ring 5, the limiting ring 62 abuts against the rotating ring 43, and the compression spring 63 is deformed and stores elastic force; it should be noted that in this embodiment, after the pressing portion 61 of the pressing ring 6 presses against the closing ring 5, the inner peripheral wall of the closing ring 5 and the outer peripheral wall of the mixing device 7 are welded and fixed.

[0074] The implementation principle of Embodiment 3 of this application is as follows: After the second precast slab 3 is installed, the closing ring 5 is sleeved on the outer side of the mixing device 7, and then the pressing ring 6 is installed and tightened. The pressing portion 61 of the pressing ring 6 is forced to press against the closing ring 5, so that the first precast slab 1 and the second precast slab 3 are firmly pressed against their respective gaskets, improving the sealing effect between the closing ring 5 and the first precast slab 1 and between the closing ring 5 and the second precast slab 3. After the closing ring 5 is pressed, the closing ring 5 is welded to the outer peripheral wall of the mixing device 7. At this time, there is no need to weld between the closing ring 5 and the first precast slab 1 anymore, improving the assembly efficiency of the overall structure.

[0075] The compression spring 63 between the limiting ring 62 and the pressing ring 6 can generate elastic force when the pressing ring 6 presses against the closing ring 5. This elastic force acts on the pressing ring 6 and the rotating ring 43 respectively, increasing the frictional force of the thread between the pressing ring 6 and the tightening disc 42 and between the rotating ring 43 and the tightening disc 42, so that the rotating ring 43 and the pressing ring 6 are not likely to rotate freely, thereby improving the stability of the overall structure.

[0076] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
