Description

Technical Field

[0001] The utility model belongs to the technical field of chimney installation, and particularly relates to an outer cylinder for a chimney which is convenient for docking. Background Art

[0002] As the main equipment for discharging flue gas, the chimney plays an important role in industrial production and daily life. Traditional chimneys usually consist of an inner cylinder and an outer cylinder. The inner cylinder is responsible for directly contacting and discharging flue gas, while the outer cylinder plays a role in protection and reinforcement. In actual applications, the inner cylinder of the chimney often needs to be spliced to meet different height requirements. However, in the prior art, the splicing operation of the inner cylinder of the chimney is relatively complex. Especially in large-scale industrial applications, high requirements are put forward for the docking accuracy and stability of the inner cylinder. If the splicing operation is improper, it may lead to insecure connection between the inner cylinders, affecting the overall use effect of the chimney and even potentially causing safety hazards.

[0003] The current chimney splicing technology has the following problems: First, during the splicing process, due to the long length and large weight of the inner cylinder, it is difficult to maintain the accurate positioning of the inner cylinder during docking, which is likely to cause uneven splicing and affect the sealing and stability of the chimney; Second, the existing splicing devices usually fail to provide sufficient supporting force. Especially during the splicing process, the end of the inner cylinder is easily affected by external forces, resulting in loosening or deformation of the docking part; Finally, since the inner cylinder is usually made of metal material, the heavy inner cylinder is likely to cause a large labor intensity to the operators during splicing, increasing the installation difficulty and time cost. Content of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide an outer cylinder for a chimney which is convenient for docking, which can achieve more convenient and stable docking operations during the splicing process of the inner cylinder, while ensuring the overall structural stability of the chimney, reducing the complexity and labor intensity of manual operations, thereby improving the installation efficiency and use safety.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An outer cylinder for a chimney which is convenient for docking, comprising a cylinder body, and an operation opening for docking the inner cylinder is penetrated and opened on the cylinder body;

[0007] An inner support is fixedly connected inside the operation opening, and the inner support is closely attached to the opening edge of the operation opening;

[0008] Vertical rods are fixedly connected to both outer sides of the inner support;

[0009] A support plate is fixedly connected between the bottom of the vertical rod and the cylinder body.

[0010] Further, first reinforcing members are arranged at equal intervals along the length direction on the outer side of the support plate, and the bottom of the first reinforcing member is fixedly connected to the outer side of the cylinder body.

[0011] Further, a baffle is fixedly connected to one ends of the two longitudinal rods, and the bottom of the baffle is fixedly connected to the outer side surface of the cylinder body.

[0012] Further, second reinforcing members are fixedly connected at equal intervals along the length direction on the outer side of the baffle, and the bottom of the second reinforcing member is fixedly connected to the outer side surface of the cylinder body.

[0013] Further, a cross bar is fixedly connected to the other ends of the two longitudinal rods, and the cross section of the cross bar is in an L shape.

[0014] Further, a reinforcing frame is fixedly connected to the outer side of the open end at the top of the inner support, and the bottom of the reinforcing frame is fixedly connected to the top end of the longitudinal rod.

[0015] Further, a cover plate is arranged between the cross bar and the inner support, and both ends of the cover plate are fixedly connected to the longitudinal rod.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] The outer cylinder structure for a chimney provided by the present utility model, by arranging the inner support, enables sufficient support to be obtained inside the cylinder body during the splicing operation of the inner cylinder. This design effectively solves the problems in the prior art that due to the large weight of the inner cylinder, instability and inaccurate positioning are likely to occur during splicing. The inner support is closely attached to the opening edge of the operation port, ensuring that the operation port will not damage the overall structural stability of the cylinder body during the splicing process, thereby improving the service life and safety of the chimney.

[0018] In addition, by fixedly connecting the longitudinal rods and the support plate on both sides of the inner support, the structural strength and stability of the cylinder body are further enhanced. The design of the longitudinal rods and the support plate can effectively prevent the structure around the operation port from deforming or being damaged due to uneven force during the splicing process of the inner cylinder, thereby solving the problem of insufficient splicing accuracy in the prior art. At the same time, the first reinforcing members arranged on the support plate and the second reinforcing members arranged on the baffle, by being arranged at equal intervals along the length direction, reinforce the overall structure, ensuring that the stability of the cylinder body will not be affected by vibration or external environmental factors during the long-term use of the chimney.

[0019] By setting a cross bar and a reinforcing frame between two vertical bars, the structural strength of the cylinder is further enhanced. The L-shaped cross bar not only enhances the bending resistance of the vertical bars but also provides a larger supporting area, effectively solving the problem of uneven stress that may occur during the splicing process of the inner cylinder. The reinforcing frame is fixedly connected to the top end of the vertical bar, further strengthening the supporting effect of the inner support, ensuring that the inner cylinder can be firmly butted during splicing and preventing the overall structural stability from being affected by the loosening of the inner support.

[0020] Finally, the cover plate design between the inner support and the cross bar plays a protective role, avoiding interference from external foreign objects during the splicing operation and providing additional support for the entire structure. This design not only improves the installation efficiency of the chimney but also reduces the complexity and labor intensity of manual operations, effectively solving the problems of difficult splicing and increased time cost caused by complex operations in the prior art.

[0032] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model and does not strictly limit the specific scope of protection claimed by the present utility model.

[0033] Refer to Figures 1-4, An outer cylinder for a chimney that is convenient for docking, including a cylinder body 1, and an operation opening 11 for docking an inner cylinder is penetrated through the cylinder body 1; the size and position of the operation opening 11 are precisely designed to ensure that the inner cylinder can smoothly pass through and closely fit with the inner wall of the outer cylinder during docking, thereby improving the sealing and stability of the chimney; an inner support 2 is fixedly connected inside the operation opening 11, and the inner support 2 is made of a high-strength material to withstand various external forces generated during the docking operation; the shape of the inner support 2 coincides with the opening shape of the operation opening 11, and the inner support 2 is closely attached to the opening edge of the operation opening 11. This design can effectively support the cylinder body 1 and keep it stable during the operation; longitudinal rods 3 are fixedly connected to both outer sides of the inner support 2, and the longitudinal rods 3 are thickened to enhance the strength and durability of the overall structure; a support plate 4 is fixedly connected between the bottom of the longitudinal rod 3 and the cylinder body 1. The support plate 4 is arranged at a precisely calculated position and can evenly disperse the pressure on the cylinder body 1, so as to ensure that when the cylinder body 1 is erected, the opened operation opening 11 will not damage the overall structural stability of the cylinder body 1.

[0034] Refer to Figure 2 , on the outer side of the support plate 4, first reinforcement members 41 are fixedly connected at equal intervals along its length direction. The shape and size of the first reinforcement members 41 are optimized to ensure that the load-bearing capacity of the support plate 4 can be maximally enhanced during the installation process; and the bottom of the first reinforcement member 41 is fixedly connected to the outer side of the cylinder body 1, and the bottom connection method of the reinforcement member uses welding technology to ensure the firmness and durability of the connection, preventing loosening or damage during long-term use, thereby further enhancing the overall structural strength of the cylinder body 1.

[0035] Refer to Figure 3 , at one end of the two longitudinal rods 3, a baffle 6 is fixedly connected. The material of the baffle 6 is selected as a metal material with high strength and corrosion resistance to ensure its long service life in a harsh environment; the bottom of the baffle 6 is fixedly connected to the outer side surface of the cylinder body 1, and the connection part is thickened to improve its anti-impact ability, so as to ensure that a stable support effect is provided for the inner support 2 during the splicing process of the inner cylinder; the design of the baffle 6 can not only improve the overall structural strength of the chimney, but also prevent interference from the external environment to the inner cylinder docking operation during operation.

[0036] Refer to Figure 3 , on the outer side of the baffle 6, second reinforcement members 61 are fixedly connected at equal intervals along its length direction. The second reinforcement members 61 are made of the same material as the baffle 6, have good strength and durability, and can play a further supporting and fixing role for the baffle 6 during use; and the bottom of the second reinforcement member 61 is fixedly connected to the outer side surface of the cylinder body 1, and its firm connection with the cylinder body 1 is ensured through welding technology, so as to ensure that the reinforcement member will not loosen due to vibration or external force during the use of the chimney, further improving the overall stability and safety of the chimney.

[0037] Refer to Figure 2 Figure 2 , at the other ends of the two longitudinal rods 3, a cross bar 5 is fixedly connected. The cross bar 5 has an L-shaped cross section. The L-shaped design not only endows the cross bar 5 with good anti-bending performance, but also provides a larger supporting area during the installation process to ensure that when docking with the inner cylinder, the external force can be effectively dispersed to prevent the inner cylinder from being unevenly stressed and resulting in docking failure.

[0038] Refer to Figure 1 Figure 1 , on the outer side of the open end at the top of the inner support 2, a reinforcing frame 21 is fixedly connected. The structure of the reinforcing frame 21 is optimized and can provide a stronger supporting effect during the docking of the inner cylinder; the bottom of the reinforcing frame 21 is fixedly connected to the top end of the longitudinal rod 3. Through the close connection between the reinforcing frame 21 and the longitudinal rod 3, the stability of the entire supporting structure is further enhanced, ensuring that when the cylinder body 1 is erected, the overall docking operation will not be affected due to the loosening of the internal structure.

[0039] Refer to Figure 2 Figure 2 , between the cross bar 5 and the inner support 2, a cover plate 7 is provided. The two ends of the cover plate 7 are fixedly connected to the longitudinal rod 3. The cover plate 7 can not only prevent external foreign objects from entering the operation port 11 and affecting the docking operation of the inner cylinder, but also provide additional support and protection for the overall structure through its firm connection with the longitudinal rod 3, ensuring the safety and reliability of the chimney during long-term use.

[0040] The working principle of the present utility model is as follows:

[0041] The chimney is divided into an inner cylinder and an outer cylinder. When splicing the inner cylinder of the chimney, the inner support 2 enters the inside of the cylinder body 1, so that it is convenient to perform the docking operation when splicing the inner cylinder of the chimney;

[0042] The provided inner support 2 can provide support inside the operation port 11 opened on the cylinder body 1. The longitudinal rods 3 and the support plates 4 on both sides of the inner support 2 can longitudinally reinforce the inner support 2. When the cylinder body 1 is erected, the opened operation port 11 will not damage the overall structural stability of the cylinder body 1;

[0043] The baffles 6 and the cross bar 5 at both ends of the longitudinal rod 3 connect the two longitudinal rods 3 into a whole, so as to further provide support for the inner support 2.

[0044] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model.
