Description

Technical Field

[0001] The present application belongs to the technical field of heat exchangers, and in particular, relates to a heat exchanger. Background Art

[0002] A heat exchanger is a device that can cool and protect the burner, and can prevent the burner from being damaged by high-temperature thermal radiation. It is widely used in many industrial systems that require burners, such as coal gas, boilers, fuel gas, and oil. The function of the head cooling water coil is to protect the burner head to prevent the process burner from being damaged by high-temperature thermal radiation. Since the stability of the burner cooling water system is directly related to the safe operation and service life of the burner, the reliability of the entire cooling water system must be improved to avoid frequent failures of the cooling water system.

[0003] In the industrial production process, the heat exchanger is a kind of equipment widely used in various process flows. Its main function is to heat the raw materials to the required temperature to realize various process flows. However, the traditional heat exchanger has certain limitations. For example, only a single input pipe is used for gas input, which further limits the air volume of the gas entering. At the same time, the existing device cannot accurately measure the gas input volume. When the air volume is large enough, the air volume is easy to damage the pipeline. At the same time, the existing device cannot filter the input gas, and the burner input and output are prone to blockage, which further limits the use effect and work efficiency of the device.

[0004] To this end, we propose a heat exchanger to solve the above problems. Utility Model Content

[0005] The purpose of the present application is to propose a heat exchanger to solve the problem in the prior art that the gas input amount cannot be effectively monitored and controlled, and the gas cannot be effectively filtered, which easily causes pipeline blockage.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A heat exchanger comprises a protective tube, wherein an inner tube is clamped inside the protective tube, and two groups of connecting tubes and an exhaust pipe are fixedly connected to the outer surface of the protective tube, each of the connecting tubes is provided with an air inlet pipe on the outside, and flanges are clamped on the outer surface of each air inlet pipe and the outer surface of the connecting tube, and two groups of bolts are commonly threadedly connected to the inner wall of each group of flanges, a first filter screen, a second filter screen and filter cotton are clamped inside each of the connecting tubes, an air volume sensor is fixedly connected to the outer surface of each air inlet pipe, a detection probe is fixedly connected to the outer surface of each air volume sensor, and a controller is fixedly connected to the outer surface of the protective tube.

[0008] Preferably, a buffer spring is sleeved on the outer surface of each of the bolts, and the outer surface of each of the buffer springs is in contact with the outer surfaces of the two flanges respectively.

[0009] Preferably, the outer surface of each bolt is threadedly connected with a nut, and the outer surface of each nut is in contact with the outer surface of the flange.

[0010] Preferably, the outer surface of each of the air volume sensors is fixedly connected with a clamping ring, and the outer surface of each of the clamping rings is fixedly connected to the outer surface of the air inlet pipe.

[0011] Preferably, the outer surface of the controller and the bottom surface of the controller are both fixedly connected with two trapezoidal blocks, and the back surface of each of the trapezoidal blocks is fixedly connected with the outer surface of the protective tube.

[0012] Preferably, a collar is sleeved on the outer surface of the discharge pipe, and the outer surface of the collar is fixedly connected to the outer surface of the protection pipe.

[0013] In summary, the technical effects and advantages of this application are:

[0014] By setting the cooperation of the air inlet duct, the air volume sensor and the detection probe, the air volume entering the air inlet duct can be monitored in time. When the air volume is large enough, the staff controls the number of air inlet ducts opened, which is beneficial to improving the use effect and work efficiency of the device. The flange, the first filter screen, the second filter screen and the filter cotton are used to facilitate the disassembly between the connecting pipe and the air inlet duct, which is beneficial to the replacement and cleaning of the first filter screen, the second filter screen and the filter cotton, further improving the filtering effect of the heat exchanger, avoiding the heat exchanger from being blocked by impurities, and further reducing the use effect and work efficiency of the device.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A heat exchanger includes a protective tube 1, an inner tube 3 is clamped inside the protective tube 1, two groups of connecting tubes 11 and a discharge pipe 9 are fixedly connected to the outer surface of the protective tube 1, a sleeve ring 8 is sleeved on the outer surface of the discharge pipe 9, and the outer surface of the sleeve ring 8 is fixedly connected to the outer surface of the protective tube 1. By providing the sleeve ring 8, the discharge pipe 9 can be fixed to avoid the problem of fluctuation of the discharge pipe 9 during use.

[0022] An air inlet pipe 2 is provided on the outside of each connecting pipe 11, and a flange 10 is clamped on the outer surface of each air inlet pipe 2 and the outer surface of the connecting pipe 11. The inner walls of each set of flanges 10 are commonly threaded with two sets of bolts 5, and a buffer spring 15 is sleeved on the outer surface of each bolt 5. The outer surface of each buffer spring 15 is in contact with the outer surfaces of the two flanges 10 respectively. By providing the buffer spring 15, the bolt 5 can be buffered and protected, thereby further improving the service life of the device, avoiding the problem of damage of the bolt 5 due to long-term use, and further reducing the use effect and work efficiency of the device.

[0023] The interior of each connecting pipe 11 is clamped with a first filter screen 13, a second filter screen 14 and filter cotton 18, and the outer surface of each bolt 5 is threadedly connected to a nut 12, and the outer surface of each nut 12 is in contact with the outer surface of the flange 10. By providing the nut 12, the bolt 5 can be fixed to avoid the problem of the bolt 5 loosening during use, which may easily cause air leakage and falling at the connection of the flange 10, thereby affecting the use effect and work efficiency of the device.

[0024] The outer surface of each air inlet pipe 2 is fixedly connected to an air volume sensor 4, and the outer surface of each air volume sensor 4 is fixedly connected to a clamping ring 17. The outer surface of each clamping ring 17 is fixedly connected to the outer surface of the air inlet pipe 2. By providing the clamping ring 17, the air volume sensor 4 can be fixed to avoid shaking during use of the air volume sensor 4, thereby extending the service life of the device.

[0025] The outer surface of each wind volume sensor 4 is fixedly connected to a detection probe 16, the outer surface of the protective tube 1 is fixedly connected to a controller 7, the outer surface of the controller 7 and the bottom surface of the controller 7 are fixedly connected to two trapezoidal blocks 6, and the back side of each trapezoidal block 6 is fixedly connected to the outer surface of the protective tube 1.

[0026] The working principle of the utility model is as follows: when in use, first connect the controller 7 and the air volume sensor 4 to the power supply. When the device is used, the staff controls the number of air inlet pipes 2 entering the device according to the needs, and then controls the air volume entering the heat exchanger. The controller 7 is used to control the air volume sensor 4 to work. When the value of the air volume sensor 4 is large, the controller 7 is used to pay attention to it in time. Then the staff uses the sealing structure to seal and close the multiple air inlet pipes 2. Air only enters through a single air inlet pipe 2, so as to control the air volume entering the heat exchanger, which is beneficial to improving the use effect and work efficiency of the device. In the process of wind entering the connecting pipe 11 through the air inlet pipe 2, it will pass through the detection below the air volume sensor 4 The probe 16 performs real-time detection of the air volume, which is beneficial to the protection of the pipeline and avoids damage to the pipeline caused by excessive air volume. The detected air volume is filtered through the second filter 14, the filter cotton 18 and the first filter 13 in turn, so as to filter out impurities and enter the protection tube 1. Through this device, after a period of use, the flange 10, the connecting pipe 11 and the air inlet pipe 2 are disassembled from the flange 10 by utilizing the relationship between the connecting pipe 11 and the air inlet pipe 2 and the flange 10 respectively, and the first filter 13, the second filter 14 and the filter cotton 18 are tilted at the same time, which is beneficial to improve the filtering effect of the device, thereby effectively avoiding the blockage of the pipeline caused by impurities, and further improving the service life and use effect of the device.
