Description
Technical Field
[0001] The utility model relates to the technical field of flue gas pipes, in particular to a flue gas pipe made of cement. Background Art
[0002] A flue duct is a tubular device for discharging waste gas and smoke. A residential flue refers to a vertical pipe product used to remove kitchen smoke or bathroom waste gas. It is also called an exhaust duct, ventilation duct, or residential exhaust duct. Cement flue ducts are mostly rectangular.
[0003] However, in the prior art, the length of the existing flue gas duct is generally consistent with the height of the floor, and the height of the floor is generally about three meters, which results in a long length of the flue gas duct, which is inconvenient to transport and install. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art: the length of the flue gas duct is generally consistent with the height of the floor, and the height of the floor is generally about three meters, which results in a long length of the flue gas duct, which is inconvenient to transport and install.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a cement flue gas duct, including a cement flue gas duct, the outer surface of the cement flue gas duct is fixedly connected to a docking plate near its bottom position, and an insertion hole is provided on the docking plate, the outer surface of the cement flue gas duct is fixedly connected to a connecting sleeve near its top position, movable rods are slidably inserted at both ends of the connecting sleeve, and one end of the movable rod is fixedly connected to a fixed plate, and both ends of the fixed plate are located at the upper end of the movable rod and are fixedly connected to docking rods, bolts are threadedly connected to the connecting sleeve and the fixed plate, and a steel bar is penetrated and engaged at the top position of one side of the cement flue gas duct.
[0006] As a preferred embodiment, a wire mesh is embedded and fixed in the cement fume duct.
[0007] As a preferred embodiment, a sealing convex plate is fixedly connected to the bottom end surface of the cement fume duct, and a groove is provided on the top end surface of the cement fume duct.
[0008] As a preferred embodiment, one end of the movable rod is fixedly connected to a limit plate, and the limit plate is slidably connected in the connecting sleeve.
[0009] As a preferred embodiment, the length of the movable rod is greater than the length of the docking rod.
[0010] Compared with the prior art, the advantages and positive effects of the present invention are:
[0011] The utility model enables two sections of cement smoke ducts to be vertically butted together with the help of a connecting sleeve. After butting, the fixing plate is pushed so that the butt plug rod and the movable rod are completely pushed into the butt plate and the connecting sleeve at one end, thereby reinforcing the assembly of the two sections of cement smoke ducts and improving stability. The operation steps for assembling the two sections of cement smoke ducts are simple and quick, and the cement smoke ducts can be easily increased in overall length through assembly, so that the length of a single section of cement smoke duct before assembly does not need to be the same height as the floor, thereby effectively reducing the length of a single section and facilitating subsequent transportation and installation.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example 1
[0020] like Figure 1-4As shown, the utility model provides a technical solution: a cement flue gas duct, comprising a cement flue gas duct 1, an outer surface of the cement flue gas duct 1 is fixedly connected to a docking plate 2 near its bottom position, and an insertion hole is opened on the docking plate 2, and the outer surface of the cement flue gas duct 1 is fixedly connected to a connecting sleeve 4 near its top position, with the help of the enclosure limit of the connecting sleeve 4, it is convenient to make the upper and lower ends of the two sections of the cement flue gas ducts 1 vertically docked, and movable rods 6 are slidably inserted at both ends of the connecting sleeve 4, and one end of the movable rod 6 is fixedly connected to a fixing plate 8, and both ends of the fixing plate 8 are located at the upper end of the movable rod 6 and are fixedly connected to a docking rod 5. After the two sections of the cement flue gas ducts 1 are docked, the fixing plate 8 is pushed so that the docking rod 5 and the movable rod 6 are completely pushed into the docking plate 2 and the connecting sleeve 4 at one end, thereby accelerating the assembly of the two sections of the cement flue gas ducts 1. To improve stability, bolts 9 are threadedly connected on the connecting sleeve 4 and the fixing plate 8. The fixing plate 8 is fixed by installing the bolts 9 to improve its own stability. The assembling steps of the two sections of cement smoke ducts 1 are simple and quick, which makes it easy for the cement smoke duct 1 to increase its overall length through assembly, so that the length of a single section of cement smoke duct 1 before assembly does not need to be the same as the floor height, effectively reducing its single section length, which is convenient for subsequent transportation and installation. A steel bar 10 is penetrated and engaged near the top position of one side of the cement smoke duct 1. When each section of the cement smoke duct 1 is assembled on the wall of the floor, the steel bar 10 is taken out and inserted into the reserved hole on the top of one side of the cement smoke duct 1 close to the wall. Then the steel bar 10 passes through the cement smoke duct 1 and is inserted into the reserved hole on the wall, so as to improve the stability of the cement smoke duct 1 when erected on the wall of each floor.
[0021] Example 2
[0022] like Figure 1-4As shown, a wire mesh is embedded and fixed in the cement smoke pipe 1. The addition of the wire mesh serves to improve the strength and stability of the cement smoke pipe 1. A sealing convex plate 3 is fixedly connected to the bottom surface of the cement smoke pipe 1, and a groove is provided on the top surface of the cement smoke pipe 1. By applying some concrete mortar in the groove, when the two sections of the cement smoke pipe 1 are assembled, the sealing convex plate 3 of one section of the cement smoke pipe 1 will be stuck into the groove of the other section of the cement smoke pipe 1. In this way, with the help of concrete mortar, the stability of the two sections of the cement smoke pipe 1 during docking and assembly can be improved, and the assembly connection of the cement smoke pipe 1 can also be improved. For the purpose of sealing, one end of the movable rod 6 is fixedly connected to the limiting plate 7, and the limiting plate 7 is slidably connected in the connecting sleeve 4. The setting of the limiting plate 7 effectively prevents the movable rod 6 from being separated from the connection of the connecting sleeve 4, and prevents the docking rod 5, movable rod 6 and fixed plate 8 on the single section of cement smoke pipe 1 from being lost during transportation. The length of the movable rod 6 is greater than the length of the docking rod 5. In this way, when the fixed plate 8 is pulled outward until it stops due to the obstruction of the limiting plate 7, the docking rod 5 can move out of the top range of the connecting sleeve 4, avoiding it from interfering with the edge connection of the connecting sleeve 4 and the docking plate 2 when the two sections of cement smoke pipe 1 are assembled.
[0023] Working principle:
[0024] like Figure 1-4 As shown, when the present invention is in use, the user needs to apply concrete mortar to the groove of each section of cement smoke pipe 1 before assembling it. Then, when assembling the cement smoke pipe 1 to the designated wall of the floor, the user first needs to insert the lower end of one section of cement smoke pipe 1 into the connecting sleeve 4 of the other section of cement smoke pipe 1. When the docking plate 2 and the connecting sleeve 4 on the two sections of cement smoke pipe 1 are in contact with each other, it indicates that the insertion is completed. At this time, the sealing convex plate 3 of one section of cement smoke pipe 1 will be stuck into the groove of the other section of cement smoke pipe 1, and the sealing convex plate 3 will contact the concrete mortar in the groove, thereby improving the sealing and stability of the assembly connection. Then manually push the fixed plate 8 to drive the docking rod 5, movable rod 6 and limit plate 7 to move, and push the docking rod 5 and movable rod 6 completely into the docking plate 2 and connecting sleeve 4 at one end, and then fix the fixed plate 8 to the connecting sleeve 4 by installing bolts 9, thereby completing the assembly of the two sections of cement smoke pipes 1. When each section of cement smoke pipe 1 is assembled on the wall of the floor, take out the steel bar 10 and insert it into the reserved hole in the cement smoke pipe 1 near the top of one side of the wall. Then, the steel bar 10 passes through the cement smoke pipe 1 and is inserted into the reserved hole on the wall, so as to improve the stability of the cement smoke pipe 1 when erected on the wall of each floor.
