[0042] Referring to Figure 1 and the accompanying Figure 2 shown, Figure 1 a structure schematic diagram of the steam cylinder provided by the embodiment of the present application. Figure 2 A partial structure enlargement view of the steam cylinder provided by the embodiment of the present application, showing a steam cylinder, which includes: an inner container cylinder 1000, an inner container head 1001 and a first assembly connection assembly.

[0043] The inner container cylinder 1000 is provided with a first port, which is connected to a first space inside the inner container cylinder 1000. The inner container head 1001 is provided with a second port, which is connected to a second space inside the inner container head 1001. The first assembly connection assembly includes a first assembly part 2000 and a second assembly part 2001 that can be assembled with each other. The first assembly part 2000 is provided with a first through hole, which penetrates the two sides of the first assembly part 2000. The second assembly part 2001 is provided with a second through hole, which penetrates the two sides of the second assembly part 2001. The inner container cylinder 1000 is connected to one side of the first assembly part 2000, and the first through hole is connected to the first port. The inner container head 1001 is connected to one side of the second assembly part 2001, and the second through hole is connected to the second port. When the first assembly part 2000 and the second assembly part 2001 are assembled, the first through hole and the second through hole are connected, and the first space and the second space form a whole space inside the inner container. The medium inside the inner container will be stored and moved in the first space and the second space.

[0044] When the inner container cylinder 1000 is connected to the first assembly part 2000, it is ensured that the first through hole is connected to the first port. Similarly, when the inner container head 1001 is connected to the second assembly part 2001, the second through hole is connected to the second port. After the first assembly part 2000 and the second assembly part 2001 are assembled, the first through hole and the second through hole are connected. This connection arrangement allows the formation of a passage inside the split cylinder, and the medium (such as steam) can enter the inner container head 1001 from the inside of the inner container cylinder 1000 through the first through hole and the second through hole, or vice versa. If the inner container cylinder 1000 or the inner container head 1001 is damaged, etc., only the first assembly connection assembly needs to be disassembled, and the damaged part can be taken out separately for repair or replacement. Compared with the whole split cylinder, this split cylinder greatly reduces the maintenance cost and time. The arrangement of the first through hole and the second through hole ensures the smooth flow of the medium between the inner container cylinder 1000 and the inner container head 1001 of the split cylinder. For example, in the scenario of using the split cylinder for steam distribution, steam is transported from the boiler room to the inner container cylinder 1000 of the split cylinder, then enters the inner container head 1001 through the first through hole and the second through hole, and is then distributed to each device that needs steam from the outlet of the inner container head 1001.

[0045] In some embodiments of the present application, the first assembly part 2000 is provided as a first flange, and the second assembly part 2001 is provided as a second flange. The first flange is provided with a first connecting part 2002, and the second flange is provided with a second connecting part 2003.

[0046] The first assembly connecting assembly further comprises a first fixed connecting piece, which is assembled on the first connecting part 2002 and the second connecting part 2003 to connect the first connecting part 2002 and the second connecting part 2003; when the first connecting part 2002 and the second connecting part 2003 are connected, the first through hole and the second through hole are in communication.

[0047] The first through hole of the first flange plate and the second through hole of the second flange plate are matched in diameter and position, and when the two flange plates are tightly connected through the first connecting part 2002 and the second connecting part 2003, the two through holes can be naturally aligned, thereby ensuring that the medium (such as steam) can flow smoothly.

[0048] The flange plate connection and the fastening through the first fixed connecting piece can realize tight connection. During the operation of the cylinder, especially when dealing with high-temperature and high-pressure medium (such as steam), such tight connection can effectively prevent leakage of the medium. For example, when the steam pressure in the cylinder is high, the tight connection between the flange plates can withstand the pressure and ensure the safe operation of the system.

[0049] In some embodiments of the present application, the first fixed connecting piece comprises a nut 2005 and a screw rod 2006; the first connecting part 2002 is provided with a first connecting hole, and the second connecting part 2003 is provided with a second connecting hole; the screw rod 2006 can penetrate through the first connecting hole and the second connecting hole, and the nut 2005 is used to assemble on both ends of the screw rod 2006.

[0050] During assembly, after the screw rod 2006 is inserted into the first connecting hole and the second connecting hole, the nut 2005 is tightened on both ends of the screw rod 2006, so that the first flange plate and the second flange plate can be tightly connected together. This connection mode can ensure the firmness of the connection, and the tightness of the connection can be controlled by the degree of tightening.

[0051] The first connecting hole is provided on the first connecting part 2002, and the first connecting part 2002 can be arranged at the edge of the first flange plate;

[0052] The second connecting hole is provided on the second connecting part 2003, and the second connecting part 2003 can be arranged at the edge of the second flange plate. The positions of these first connecting holes and second connecting holes are accurately designed to ensure that the two flange plates can be accurately connected through the screw rod 2006 during assembly. The connecting holes are usually circumferentially distributed on the edge portion of the flange plate, so that the connecting force can be uniformly distributed on the flange plate.

[0053] In some embodiments of the present application, the opening edge of the first port is welded to one side of the first assembly part 2000, and the opening edge of the second port is welded to one side of the second assembly part 2001. During the welding process, a first weld seam is formed between the opening edge of the first port and the first assembly part, and the welding fills the first weld seam to form a first solder part, and the opening edge of the first port and the first assembly part are connected through the first solder part. The first solder part is processed so that the surface of the first solder part is a smooth surface.

[0054] Similarly, during the welding process, a second weld seam is formed between the opening edge of the second port and the second assembly part, and the welding fills the second weld seam to form a second solder part, and the opening edge of the second port and the second assembly part are connected through the second solder part. The second solder part is processed so that the surface of the second solder part is a smooth surface.

[0055] The first solder part and the second solder part are formed by melting and solidifying the welding material commonly used in welding operations. For details, refer to the prior art.

[0056] For the above processing, specifically including: when welding the first port edge and one side of the first assembly part 2000 (for example, the first flange), to ensure the welding quality, first, the welding site should be cleaned to remove rust, oil stains and other impurities to ensure the firmness of the welding. The welding method of the second port edge and the second assembly part 2001 (for example, the second flange) is the same.

[0057] Since the inner liner cylinder 1000 and the inner liner head 1001 are connected in a split type, the inner liner cylinder 1000 and the inner liner head 1001 can be polished separately during production. For example, after the welding of the inner liner cylinder 1000 and the first flange is completed, the inner liner cylinder 1000 is placed alone on the polishing equipment, and the appropriate polishing wheel and polishing paste are used to polish the welding seam. Similarly, the inner liner head 1001 can also be polished alone after being welded with the second flange. During pickling and passivation and electrolytic polishing, the inner liner cylinder 1000 and the inner liner head 1001 can also be separated. During pickling and passivation, the inner liner cylinder 1000 and the inner liner head 1001 are respectively placed in a pickling and passivation solution (such as a mixed solution of nitric acid and hydrofluoric acid), and the soaking time and temperature are controlled. Generally, the soaking time is 30-60 minutes, and the temperature is 40-60℃, so that the metal oxides on the surface of the inner liner cylinder 1000 and the inner liner head 1001 react with the acid solution to form a passivation film. During electrolytic polishing, the inner liner cylinder 1000 and the inner liner head 1001 are used as electrodes and are respectively placed in an electrolytic polishing solution (such as a mixed solution of phosphoric acid, sulfuric acid and chromic anhydride), and the current density and polishing time are controlled to achieve electrolytic polishing of the surface.

[0058] The full polishing of the welding bead can remove the oxides, spatters and other impurities generated during the welding process, so that the surface of the liner cylinder 1000 and the liner head 1001 is smoother. After pickling, passivation and electrolytic polishing, the passivation film formed on the surface of the liner cylinder 1000 and the liner head 1001 can prevent further oxidation of the metal and improve the smoothness of the surface. When the split cylinder is used in the food, pharmaceutical and other industries with high cleanliness requirements, such a high-cleanliness surface can effectively prevent the attachment of impurities and the breeding of bacteria, ensuring the purity of the medium in the split cylinder.

[0059] Splitting to process each component (such as polishing, pickling, passivation and electrolytic polishing) can better control the quality of each component. Because each component can be processed under more suitable process parameters, the processing effect will not be affected by the limitations of the overall structure. For example, during electrolytic polishing, the liner cylinder 1000 and the liner head 1001 can adjust the current density and polishing time according to their own size and material characteristics, so that each component can achieve the best polishing effect, thereby improving the quality of the entire split cylinder.

[0060] After the above treatment, because the liner cylinder 1000, the liner head 1001, the first assembly part 2000 and the second assembly part 2001 can be disassembled respectively, they can be polished and pickled respectively. Even after the liner cylinder 1000 is assembled with the first assembly part 2000, and the liner head 1001 is assembled with the liner head 1001, the welded position can still be processed. The welded position becomes a smooth and flat transition area, so that when the medium (such as steam) enters the liner, bacteria will not accumulate at the welded position, thereby meeting higher cleanliness requirements.

[0061] In some embodiments of the present application, reference is made to the drawings attached hereto Figure 3 and attached Figure 4 , Figure 3 for Figure 2 the partial enlarged view of A in FIG. 1. Figure 4 is a side view of a split cylinder provided by an embodiment of the present application. The split cylinder also includes a heat-insulating shell, which includes a shell cylinder 3000, a shell head 3001 and a transition connecting cylinder 3002. The shell cylinder 3000 is sleeved outside the liner cylinder 1000 and is provided with a third port, which communicates with the inside of the shell cylinder 3000.

[0062] The shell head 3001 is provided with a fourth port, which communicates with the inside of the shell head 3001.

[0063] The transition connecting cylinder 3002 includes a first mounting surface and a second mounting surface, and the fourth port of the shell head 3001 is sealingly connected to the first mounting surface, and the third port of the shell cylinder 3000 is detachably connected to the second mounting surface.

[0064] The shell cylinder 3000 is sleeved outside the inner cylinder 1000, and the inner diameter thereof should be slightly larger than the outer diameter of the inner cylinder 1000, so as to be smoothly sleeved. When being installed, the concentricity of the two should be paid attention to, which can be ensured by setting a positioning ring outside the inner cylinder 1000 or a guide groove inside the shell cylinder 3000 and the like.

[0065] The fourth port of the shell head 3001 is sealingly connected with the first mounting surface of the transition connecting cylinder 3002. When being connected, a sealing gasket can be used to ensure the sealing effect. For example, a suitable rubber sealing gasket is selected, which is matched in shape with the fourth port of the shell head 3001 and the first mounting surface of the transition connecting cylinder 3002, is placed between the two, and then the shell head 3001 and the transition connecting cylinder 3002 are tightly connected together by welding or bolt 3005 connection and the like. When being welded, the sealing property of the weld should be ensured; when being bolt 3005 connected, the bolt 3005 should be tightened to make the sealing gasket fully compressed, so as to prevent leakage.

[0066] The existence of the heat preservation shell can effectively reduce the heat loss of the medium (such as steam) in the inner cylinder. The shell cylinder 3000 and the shell head 3001 wrap the inner cylinder to form a relatively closed heat preservation space. For example, in the case that the steam cylinder is used for steam distribution, when the steam is transmitted in the inner cylinder, the heat will be conducted outward through the inner cylinder wall, and the heat preservation shell can prevent the rapid dissipation of heat, so that the steam can maintain a high temperature for a long time, thereby improving the energy utilization efficiency.

[0067] The detachable connection mode of the shell cylinder 3000 and the transition connecting cylinder 3002 facilitates the inspection and maintenance of the inside of the heat preservation shell. If it is necessary to check whether the inner cylinder 1000 or the heat preservation material inside the heat preservation shell is damaged or the like, the shell cylinder 3000 can be easily detached. For example, when it is found that the heat preservation effect of the steam cylinder is reduced, the maintenance personnel can first detach the shell cylinder 3000, check whether the heat preservation material is damp or falls off or the like, and then carry out targeted maintenance or replacement.

[0068] In some embodiments of the present application, a second assembly connection assembly is arranged between the shell cylinder 3000 and the shell cylinder 3000, and the second assembly connection assembly comprises a third connecting part 3003, a fourth connecting part 3004 and a second fixed connecting piece.

[0069] The third connecting part 3003 is arranged at the edge of the third port, and the fourth connecting part 3004 is arranged on the second mounting surface; the second fixed connecting piece is assembled on the third connecting part 3003 and the fourth connecting part 3004, so as to connect the third connecting part 3003 and the fourth connecting part 3004.

[0070] The third connecting part 3003 is located at the edge of the third port of the shell cylinder 3000. The third connecting part 3003 can be provided by welding a flange plate at the edge of the port. The flange plate is uniformly provided with bolt holes, and the number and size of the bolt holes are determined according to the diameter of the shell cylinder 3000 and the required connection strength. The fourth connecting part 3004 is provided on the second mounting surface of the transition connecting cylinder 3002. Its structure corresponds to the third connecting part 3003, and it is also a flange plate with bolt holes. The size of this flange plate is matched with the flange plate of the third connecting part 3003, so that the two flange plates can be tightly fitted when connected. The position, number and size of the bolt holes are completely consistent with those of the third connecting part 3003, so as to ensure that the second fixed connecting part can be smoothly installed.

[0071] In some embodiments of the present application, the second fixed connecting part is provided as a bolt 3005, and bolt holes are provided on the third connecting part 3003 and the fourth connecting part 3004. The bolt 3005 penetrates the bolt holes of the third connecting part 3003 and the fourth connecting part 3004, so as to connect the third connecting part 3003 and the fourth connecting part 3004.

[0072] After the third connecting part 3003 is connected at the edge of the third port of the shell cylinder 3000, and the fourth connecting part 3004 is connected on the second mounting surface of the transition connecting cylinder 3002, the positions of the bolt holes of the third connecting part 3003 and the fourth connecting part 3004 need to be accurately matched. The connection mode of the bolt 3005 can provide high connection strength, and connect the shell cylinder 3000 and the transition connecting cylinder 3002 together. During the operation of the split cylinder, whether it is to bear the gravity of the internal thermal insulation material, the external environmental force (such as wind force, slight collision, etc.), or in the case of thermal expansion and contraction caused by temperature change, this connection mode can maintain the stability of the shell structure.

[0073] In some embodiments of the present application, the third connecting part 3003 is welded at the opening edge of the third port, and the fourth connecting part 3004 is welded on the second mounting surface.

[0074] During the welding process, a third weld seam is formed between the opening edge of the third port and the third connecting part 3003. The welding fills the third weld seam to form a third solder part. The opening edge of the third port and the third connecting part 3003 are connected through the third solder part. The third solder part is processed so that the surface of the third solder part becomes a smooth surface.

[0075] Similarly, a fourth weld will be formed between the fourth connecting part 3004 and the second mounting surface during the welding process, and the welding will fill the fourth weld to form a fourth solder part. The fourth connecting part 3004 and the second mounting surface are connected through the fourth solder part. The fourth solder part is processed to make the surface of the fourth solder part a smooth surface.

[0076] The first solder part and the second solder part are formed by melting and solidifying the welding material commonly used in welding operations. For details, refer to the prior art.

[0077] For the above processing, specifically including: when welding the third connecting part 3003 to the opening edge of the third port of the shell cylinder 3000, first clean and pretreat the welding site. Use a grinding tool to remove rust, dirt, scale and other impurities on the port edge to ensure that the welding surface is smooth and clean. Select an appropriate welding process according to the materials of the shell cylinder 3000 and the third connecting part 3003. The process of welding the fourth connecting part 3004 to the second mounting surface of the transition connecting cylinder 3002 is similar. The mounting surface also needs to be cleaned and polished to ensure its flatness and smoothness. After completing the welding, the weld is fully polished. When pickling and passivating, the shell cylinder 3000 and the transition connecting cylinder 3002 are treated separately. When electrolytic polishing, the parts are used as electrodes and placed in the electrolytic polishing solution. The electrolytic polishing solution can be selected according to the material of the parts. For example, for stainless steel parts, a mixed solution of phosphoric acid, sulfuric acid and chromic anhydride is commonly used. Full polishing of the weld can effectively remove impurities on the surface of the weld, making the surfaces of the shell cylinder 3000 and the transition connecting cylinder 3002 smoother and cleaner. After pickling and passivation, a passivation film is formed on the surface of the part, which can prevent further oxidation of the metal and improve the smoothness of the surface. The separate structure makes it easier to inspect and maintain during the operation cycle of the equipment.

[0078] In some embodiments of the present application, a support seat 4000 is arranged below the heat preservation shell, and a clamping part is arranged on the support seat 4000 to prevent the heat preservation shell from rotating. The bottom area of the support seat 4000 is large enough to be stably placed on the ground or installation platform. If the bottom of the heat preservation shell is circular, the clamping part can be designed as an arc-shaped clamping groove, the curvature of the clamping groove matches the circumference of the bottom of the heat preservation shell, and the width of the clamping groove is slightly larger than the wall thickness of the heat preservation shell. The clamping part is not shown in the figure, and its specific setting method can be changed according to actual needs.

[0079] The setting of the clamping part can effectively prevent the thermal insulation shell from rotating during operation. When the split cylinder is working, the flow of the internal medium, external vibration or other factors may cause the thermal insulation shell to have a rotation tendency. For example, when the steam pressure in the split cylinder fluctuates or the nearby equipment vibrates, the thermal insulation shell may shake and rotate. The clamping part can limit such rotation, ensure the stability and safety of the split cylinder, and avoid the connection pipeline from being twisted, broken or other components from being damaged due to rotation.

[0080] In some embodiments of the present application, a plurality of steam exhaust pipelines 5000 are arranged on the inner container cylinder 1000, and the steam exhaust pipelines 5000 extend to the outside of the thermal insulation shell. The steam exhaust pipelines 5000 are used to connect the inside of the inner container cylinder 1000 to the outside of the thermal insulation shell.

[0081] The position of the steam exhaust pipeline 5000 on the inner container cylinder 1000 needs to consider the flow characteristics and distribution of the internal medium (such as steam) in the inner container. Generally, the steam exhaust pipeline 5000 can be arranged at the top of the inner container cylinder 1000 or near the top. Because at this position, the gas component (such as gaseous water in steam) in the medium will naturally gather, facilitating discharge. The connection part of the steam exhaust pipeline 5000 with the inside of the inner container cylinder 1000 needs to be sealed well to prevent leakage of the medium. The steam exhaust pipeline 5000 can be connected with the inner container cylinder 1000 by welding, and the welding quality needs to be ensured to avoid defects such as pores and cracks.

[0082] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present application.

[0083] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
