Description

Technical Field

[0001] This utility model relates to the field of flue hood technology, and in particular to a waste heat recovery flue hood. Background Technology

[0002] The flue hood is used for the recovery and utilization of waste heat from the surface of the waste heat recovery flue. The flue hood consists of an installation cover, a water inlet, a water outlet, and a spiral tube. When using the flue hood, the installation cover is installed on the surface of the waste heat recovery flue, so that the spiral tube is tightly fitted to the surface of the waste heat recovery flue. Then, the water outlet on the first installation cover and the water inlet on the second installation cover are fixed by a connecting pipe. Water is then introduced into the spiral tube from the water inlet, thereby being heated by the waste heat from the surface of the waste heat recovery flue, thus recovering and utilizing the waste heat from the surface of the waste heat recovery flue.

[0003] In daily work, the inventor discovered that when using the flue hood, the connection between the two spiral tubes on the flue hood is very complicated. One end of the connecting pipe is fixed to the water outlet on the previous mounting hood with a clamp, and the other end of the connecting pipe is fixed to the water inlet on the next mounting hood with a clamp. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, the connection between the two spiral pipes on the flue cover is very complicated. One end of the connecting pipe is fixed to the water outlet on the previous mounting cover with a clamp, and the other end of the connecting pipe is fixed to the water inlet on the next mounting cover with a clamp. Therefore, a waste heat recovery flue cover is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waste heat recovery flue hood, comprising a mounting hood, wherein an inlet head and an outlet head are fixedly connected to the arc surface of the mounting hood, and both the inlet head and the outlet head are provided with convenient fixing components on their arc surfaces; a connecting component is provided on the arc surface of the mounting hood; a spiral tube is fixedly connected to the inner wall of the mounting hood, one end of the spiral tube is fixed to the inlet head, and the other end of the spiral tube is fixed to the outlet head; the convenient fixing component includes a mounting cylinder fixedly connected to the arc surface of the outlet head; a connector is slidably connected to the inner wall of the mounting cylinder, and the connector is fixed to the connecting pipe; a pin is slidably inserted into the inner wall of the mounting cylinder, and the pin is inserted into the connector.

[0006] The effect achieved by the above components is as follows: by setting up a convenient fixing component, when connecting two spiral tubes, drag the connecting tube so that the connector is inserted into the mounting cylinder on the outlet head of the first mounting cover, so that the pin is inserted into the connector for fixing. Then, in the same way, the connector at the other end of the connecting tube is fixed to the inlet head on the second mounting cover, thereby connecting the two spiral tubes and thus achieving the function of connecting the two spiral tubes as conveniently as possible.

[0007] Preferably, one end of the pin is fixedly connected to a spring, and the other end of the spring is fixed to the mounting cylinder.

[0008] The effect achieved by the above components is to reset the pin by setting a spring.

[0009] Preferably, one end of the pin is fixedly connected to a pull rope, the pull rope passes through the mounting cylinder, and the other end of the pull rope is fixedly connected to a slip ring, the slip ring sliding on the mounting cylinder.

[0010] The effect achieved by the above components is that the sliding ring pulls the rope, which in turn pulls the pin.

[0011] Preferably, a sealing gasket is provided between the connector and the water outlet.

[0012] The effect achieved by the above components is to seal the connection between the connector and the outlet by setting a sealing gasket.

[0013] Preferably, the connecting assembly includes a plurality of evenly distributed fixing rods fixedly connected to the right end of the left mounting cover, the fixing rods being flexible, and a plurality of evenly distributed fixing grooves being provided at the left end of the right mounting cover, the fixing rods passing through the right mounting cover.

[0014] The effect achieved by the above components is as follows: when fixing the two mounting covers, dragging the left mounting cover causes the fixing rod to snap into the fixing groove, thereby fixing the mounting covers on the left and right sides.

[0015] Preferably, a top column is slidably connected to the inner wall of the fixing rod, and an airbag is installed on the inner wall of the fixing rod.

[0016] The effect achieved by the above components is as follows: the airbag inflates, thereby pushing the top column downward so that it touches the mounting cover, thereby squeezing the fixing rod upward, and thus assisting in limiting the fixing rod.

[0017] Preferably, the airbag and the top column are fixed together, and an air nozzle is installed on the inner wall of the fixing rod, and the air nozzle is fixed to the airbag.

[0018] The effect achieved by the above components is to connect the air nozzle to the air pump, and control the inflation and deflation of the airbag through the air pump.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by setting up a convenient fixing component, when connecting two spiral tubes, the connecting tube is dragged so that the connector is inserted into the mounting cylinder on the outlet head of the first mounting cover, and the pin is inserted into the connector for fixing. Then, in the same way, the connector at the other end of the connecting tube is fixed to the inlet head on the second mounting cover, thereby connecting the two spiral tubes. This achieves the goal of connecting the two spiral tubes as conveniently as possible, solving the problem that when the two spiral tubes on the flue cover are connected and fixed, one end of the connecting tube is fixed to the outlet head on the first mounting cover with a clamp, and the other end of the connecting tube is fixed to the inlet head on the second mounting cover with a clamp, which may make the entire connection process very cumbersome.

[0026] Reference Figure 1 and Figure 3 As shown, this utility model provides a technical solution: a waste heat recovery flue cover includes a mounting cover 1. The arc surface of the mounting cover 1 is fixedly connected to a water inlet head 5 and a water outlet head 4. The arc surfaces of the water inlet head 5 and the water outlet head 4 are both provided with convenient fixing components 2. The arc surface of the mounting cover 1 is provided with a connecting component 3. The inner wall of the mounting cover 1 is fixedly connected to a spiral tube 6. One end of the spiral tube 6 is fixed to the water inlet head 5, and the other end of the spiral tube 6 is fixed to the water outlet head 4.

[0027] The following section will explain the specific settings and functions of the convenient fixing component 2 and the connecting component 3.

[0028] Reference Figure 2 and Figure 3 As shown, in this embodiment: the convenient fixing component 2 includes a mounting cylinder 21 fixedly connected to the arc surface of the outlet head 4. A connector 22 is slidably connected to the inner wall of the mounting cylinder 21. The connector 22 is fixed to the connecting pipe 7. A pin 23 is slidably inserted into the inner wall of the mounting cylinder 21 and inserted into the connector 22. By setting the convenient fixing component 2, when connecting two spiral pipes 6, dragging the connecting pipe 7 causes the connector 22 to be inserted into the mounting cylinder 21 on the outlet head 4 of the previous mounting cover 1, so that the pin 23 is inserted into the connector 22, thereby fixing it. Then, in the same way, the connector 22 at the other end of the connecting pipe 7 is connected to the inlet head 5 on the next mounting cover 1. The two spiral tubes 6 are fixed together, thereby facilitating the connection between them. One end of the pin 23 is fixedly connected to a spring 24, and the other end of the spring 24 is fixed to the mounting cylinder 21. By setting the spring 24, the pin 23 is reset. One end of the pin 23 is fixedly connected to a pull rope 25, which passes through the mounting cylinder 21. The other end of the pull rope 25 is fixedly connected to a slip ring 26, which slides on the mounting cylinder 21. Sliding the slip ring 26 pulls the pull rope 25, which in turn pulls the pin 23. A sealing gasket 27 is provided between the connector 22 and the outlet 4 to seal the connection between them.

[0029] Reference Figure 4 As shown in this embodiment: the connecting component 3 includes multiple evenly distributed fixing rods 31 fixedly connected to the right end of the left mounting cover 1. The fixing rods 31 are flexible. Multiple evenly distributed fixing slots 32 are opened at the left end of the right mounting cover 1. The fixing rods 31 pass through the right mounting cover 1. When fixing the two mounting covers 1, the left mounting cover 1 is dragged so that the fixing rods 31 are inserted into the fixing slots 32, thereby fixing the mounting covers 1 on the left and right sides. The inner wall of the fixing rods 31 is slidably connected to the top column 33. An airbag 34 is installed on the inner wall of the fixing rods 31. When the airbag 34 inflates, it pushes the top column 33 downward so that it touches the mounting cover 1, thereby squeezing the fixing rods 31 upward, and thus assisting in limiting the fixing rods 31. The airbag 34 and the top column 33 are fixed. An air nozzle 35 is installed on the inner wall of the fixing rods 31. The air nozzle 35 is fixed to the airbag 34. The air nozzle 35 is connected to an air pump, and the air pump controls the inflation and deflation of the airbag 34.

[0030] Working principle:

[0031] When using the flue cover, install the mounting cover 1 onto the surface of the waste heat recovery flue, ensuring the spiral tube 6 is tightly fitted against the surface. Then, fix the water outlet 4 on the first mounting cover 1 and the water inlet 5 on the second mounting cover 1 using the connecting pipe 7. Water is then introduced into the spiral tube 6 through the water inlet 5, where it is heated by the waste heat from the surface of the waste heat recovery flue, thus recovering and utilizing the waste heat from the surface. When connecting the two spiral tubes 6, drag the connecting pipe 7 so that the connector 22 is inserted into the mounting cylinder 21 on the water outlet 4 of the first mounting cover 1, allowing the pin 23 to be inserted into the connector 22 for fixation. Then, in the same manner, connect the connector 22 at the other end of the connecting pipe 7 to the second mounting cover 1. The inlet head 5 is fixed, thereby connecting the two spiral tubes 6, so as to achieve the function of connecting the two spiral tubes 6 as conveniently as possible. By setting the spring 24, the pin 23 is reset, and the sliding ring 26 is slid, so that the pull rope 25 is pulled, which in turn pulls the pin 23. By setting the sealing gasket 27, the connection head 22 and the outlet head 4 are sealed. When fixing the two mounting covers 1, the left mounting cover 1 is dragged, so that the fixing rod 31 is inserted into the fixing groove 32, thereby fixing the mounting covers 1 on both sides. The air bag 34 inflates, thereby pushing the top column 33 downward, so that it touches the mounting cover 1, thereby squeezing the fixing rod 31 upward, and thus assisting in limiting the fixing rod 31. The air nozzle 35 is connected to the air pump, and the air pump controls the inflation and deflation of the air bag 34.
