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: 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.

[0006] By adopting the above technical solution, the first prefabricated plate is wavy, and after a plurality of first prefabricated plates are combined to surround the outer peripheral side of the stirring device, a plurality of temperature control channels are formed on the outer peripheral side of the stirring device. This allows the 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, a plurality of 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 force, and greatly improves the structural strength and temperature control effect of the jacket.

[0007] Optionally, a plurality of welding holes for welding are provided on the surface of the first prefabricated plate located at the first wave valley, 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 prefabricated plates close to each other abut against each other and combine to form the first wave valley.

[0008] By adopting the above-mentioned technical solution, the first prefabricated plate is welded and fixed to the outer wall of the stirring equipment through the setting of welding holes. In addition, the part where two adjacent first prefabricated plates abut each other is the first wave valley. After welding, the two adjacent first prefabricated plates are connected as a whole, so that the multiple first prefabricated plates fully surround the stirring equipment, thereby improving the temperature control effect.

[0009] Optionally, each of the first prefabricated panels is installed with a second prefabricated panel, and the second prefabricated panel is wavy and forms a plurality of second wave peaks and a plurality of second wave troughs; the plurality of first wave peaks of the first prefabricated panel and the plurality of second wave peaks of the second prefabricated panel are arranged alternately, and the second prefabricated panel separates the temperature control channel of the first prefabricated panel into a first insulation zone and two temperature control zones, and the first insulation zone is located between the first wave peak of the first prefabricated panel and the second wave trough of the second prefabricated panel, and the two temperature control zones are distributed on both sides of the first insulation zone, and the temperature control zone is located between the first wave trough of the first prefabricated panel and the second wave trough of the second prefabricated panel; the first wave trough of the first prefabricated panel and the second wave peak of the second prefabricated panel are enclosed to form a second insulation zone; the temperature control zone is used to introduce heat exchange medium, and the first insulation zone and the second insulation zone are both used to introduce insulation gas.

[0010] By adopting the above technical solution, 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 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 caused by thermal expansion and contraction or external force, and improve the service life and reliability of the jacket.

[0011] Optionally, the first wavelength band is between the first wave peak and the adjacent first wave valley of the first prefabricated plate, and the second wavelength band is between the second wave peak and the adjacent second wave valley of the second prefabricated plate; the first wavelength band and the second wavelength band are cross-arranged, the top wall of the first wavelength band is provided with a first avoidance groove for avoiding the second wavelength band, and the bottom wall of the second wavelength band is provided with a second avoidance groove for avoiding the first wavelength band; a tightening component is provided between the first wavelength band and the second wavelength band, and the tightening component is used to tighten the first wavelength band and the second wavelength band to seal the first avoidance groove and the second avoidance groove.

[0012] By adopting the above technical solution, the intersection between the first wavelength band and the second wavelength band enables the first prefabricated plate and the second prefabricated plate to fit closely together, thereby 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 the first wavelength band and the second wavelength band will not interfere at the intersection, thereby ensuring the overall smoothness of the jacket. The use of the tightening component further enhances the connection stability between the first wavelength band and the second wavelength band, effectively prevents medium leakage, and improves the sealing performance of the jacket.

[0013] Optionally, a plurality of tightening zones are formed at the intersection of the first wavelength band and the second wavelength band, and the tightening assembly includes a tightening rod, a tightening disk and a tightening member, the number of the tightening rods is arranged corresponding to the number of the tightening zones, and each of the tightening rods is passed through a corresponding tightening zone; two tightening disks are arranged and symmetrically distributed at both ends of the tightening rods, and each of the tightening disks is provided with a plurality of sliding grooves for the tightening rods to pass through; the tightening member is arranged on the tightening disk to drive all the tightening rods to synchronously move toward the center of the tightening disk.

[0014] By adopting the above-mentioned technical solution, the tightening rods are inserted into the corresponding tightening areas, and after the two ends of the tightening rods pass through the sliding grooves of the two tightening disks respectively, all the tightening rods are driven to move synchronously toward the center of the tightening disks through the tightening members, so that the multiple tightening rods are clamped at the intersection of the first wavelength band and the second wavelength band, so that the first prefabricated plate and the second prefabricated plate are connected as a whole, and the overall sealing performance is improved.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

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; 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; 3.

The closed ring 5 is connected to a gas supply pipe (not shown in the figure) for supplying gas to the heat preservation cavity 55. The gas supply pipe is used to transport the heat preservation gas.

[0047] It should be noted that, in the installation sequence of the jacket in this embodiment, the first prefabricated panel 1 is installed first, then the second prefabricated panel 3 is installed, and finally the closing ring 5 is installed; during the installation of the second prefabricated panel 3, after the tightening block 44 tightens the tightening rod 41, the tightening disk 42 can be filled with sealant to seal the sliding groove 421, thereby further improving the overall sealing.

[0048] The implementation principle of Example 2 of the present 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 insulation zone 21 and two temperature control zones 22. The temperature control zone 22 can control the temperature change in the stirring device 7, while the first insulation zone 21 and the second insulation zone 23 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 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 force, and improve the service life and reliability of the jacket.

[0049] After the second prefabricated panel 3 is inserted into the first prefabricated panel 1, the tightening assembly 4 is installed, and the tightening rods 41 are inserted into the corresponding tightening areas 24. After the two ends of the tightening rods 41 pass through the sliding grooves 421 of the two tightening disks 42 respectively, all the tightening rods 41 are driven to move synchronously toward the center of the tightening disks 42 through the tightening members, so that the multiple tightening rods 41 are clamped at the intersection of the first wavelength band 14 and the second wavelength band 33, so that the first prefabricated panel 1 and the second prefabricated panel 3 are connected as a whole, and the overall sealing performance is improved.

[0050] Example 3 The embodiment of the present application discloses a corrugated jacket of a stirring device.

[0051] Reference Fig.11 , Fig.12The difference between the corrugated jacket of a stirring device disclosed in the embodiment of the present application and embodiment 2 is that: In this embodiment, the third avoidance groove 53 is configured as a through groove that penetrates the closed ring 5, and the side walls of the closed ring 5 are respectively provided with a first embedding groove 51 for the first prefabricated panel 1 to be embedded and a second embedding groove 52 for the second prefabricated panel 3 to be embedded, and sealing gaskets (not shown in the figure) are fixedly installed in the first embedding groove 51 and the second embedding groove 52; the tightening disk 42 is provided with a tightening member, which is used to force the closed ring 5 to be pressed against the first prefabricated panel 1 and the second prefabricated panel 3.

[0052] Reference Fig.11 The clamping member is provided as a clamping ring 6, which is installed in the clamping disk 42 and is coaxially arranged with the clamping disk 42. In this embodiment, the outer peripheral wall of the clamping ring 6 is threadedly connected with the inner peripheral wall of the clamping disk 42 (the thread between the clamping ring 6 and the clamping disk 42 is not shown in the figure) so that the clamping ring 6 can rotate around its own central axis; the clamping ring 6 has a clamping portion 61, and the outer diameter of the clamping portion 61 is larger than the outer diameter of the clamping disk 42 so as to clamp the side wall of the closed ring 5 away from the first prefabricated plate 1; the driving mode of the clamping ring 6 is the same as the driving mode of the rotating ring 43, that is, the clamping ring 6 also needs to provide a docking hole 431 (not shown in the figure) for the insertion of the docking rod 81 of the driving rod 8.

[0053] Reference Fig.11 A limiting ring 62 is slidably installed on the end surface of the clamping ring 6 close to the rotating ring 43. The limiting ring 62 and the clamping ring 6 are coaxially arranged and can be displaced along the central axis of the clamping ring 6; a compression spring 63 is installed between the limiting ring 62 and the clamping ring 6, one end of the compression spring 63 is fixedly connected to the clamping ring 6, and the other end is fixedly connected to the limiting ring 62. When the clamping ring 6 is pressed against the closed ring 5, the limiting ring 62 is in contact with the rotating ring 43, and the compression spring 63 is deformed and has elastic force; it should be noted that in this embodiment, after the clamping portion 61 of the clamping ring 6 is pressed against the closed ring 5, the inner peripheral wall of the closed ring 5 and the outer peripheral wall of the stirring device 7 are welded and fixed.

[0054] The implementation principle of Example 3 of the present application is as follows: after the second prefabricated plate 3 is installed, the closing ring 5 is inserted into the outer peripheral side of the stirring device 7, and then the tightening ring 6 is installed and tightened, forcing the tightening portion 61 of the tightening ring 6 to tighten the closing ring 5, so that the first prefabricated plate 1 and the second prefabricated plate 3 are firmly pressed against their respective corresponding sealing gaskets, thereby improving the sealing effect between the closing ring 5 and the first prefabricated plate 1, and between the closing ring 5 and the second prefabricated plate 3. After the closing ring 5 is tightened, the closing ring 5 is welded to the outer peripheral wall of the stirring device 7. At this time, there is no need to weld the closing ring 5 to the first prefabricated plate 1, thereby improving the assembly efficiency of the overall structure.

[0055] The compression spring 63 between the limiting ring 62 and the clamping ring 6 can generate elastic force when the clamping ring 6 is pressed against the closing ring 5. The elastic force reacts on the clamping ring 6 and the rotating ring 43 respectively, thereby increasing the thread friction between the clamping ring 6 and the tightening disk 42 and between the rotating ring 43 and the tightening disk 42, thereby making it difficult for the rotating ring 43 and the clamping ring 6 to rotate freely, thereby improving the stability of the overall structure.

[0056] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
