Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger connection technology, specifically a heat exchanger connection device. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.

[0003] Existing heat exchanger connection methods mostly involve directly connecting the heat exchanger to a predetermined position on the corresponding device, that is, connecting the heat exchanger to the corresponding pipe on the device. However, due to the working characteristics of the heat exchanger, the water flowing through the heat exchanger is prone to precipitating scale, and this scale is easy to adhere to the inner wall of the device connected to the heat exchanger, which will eventually cause the device to malfunction, resulting in a significant impact.

[0004] Therefore, this utility model provides a heat exchanger connection device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A heat exchanger connection device of this utility model includes a water filter pipe. A concave flange water inlet pipe and a concave flange drain pipe are fixedly connected to the bottom of the water filter pipe, and the concave flange water inlet pipe and the concave flange drain pipe are arranged correspondingly. A first water filter cylinder is provided inside the water filter pipe, and one end of the first water filter cylinder contacts the inner wall of the water filter pipe. An isolation ring is provided at the other end of the first water filter cylinder. The isolation ring is fixedly connected to the inner wall of the water filter pipe. A fixing block is fixedly connected to the side wall of the water filter pipe. A threaded rod is threadedly connected inside the fixing block. A cleaning roller is fixedly connected to the end of the threaded rod. A cleaning roller is fixedly connected to the side wall of the cleaning roller. The system includes a water suction head, with multiple suction heads arranged in a linear array. The sidewall of the cleaning roller has suction holes that connect to the suction heads. A pumping pipe is fixedly connected to the bottom of the filter pipe, and a pumping pump is fixedly connected to the bottom of the pumping pipe. A motor is installed at the end of the threaded rod, and a limit plate is fixedly connected to the sidewall of the motor. This step filters water by setting up an automatic cleaning filter assembly consisting of a first filter cylinder, a cleaning roller, suction heads, a threaded rod, and a motor. Simultaneously, it achieves self-cleaning of the surface filter material of the first filter cylinder, improving the functionality of the heat exchanger connection device. This helps prevent water impurities from clogging the pipes, extends the service life of each pipe, and reduces the maintenance requirements of the device and heat exchanger.

[0007] Preferably, a flange is fixed to the end of the filter pipe; a water pump is installed on the side wall of the flange, and bolts are installed between the water pump and the flange, with multiple bolts arranged in a circumferential array; a second filter cylinder is installed inside the filter pipe, and the size of the second filter cylinder corresponds to that of the isolation ring; this step, by setting the flange and the water pump, allows the end of the filter pipe to be opened, and by setting the second filter cylinder to filter larger impurities, improves the flexibility and practicality of the device, facilitates the cleaning of the device components by the staff, reduces the difficulty of device maintenance, helps to shorten the maintenance time, and ensures the normal operation of the heat exchanger.

[0008] Preferably, the filter tube is provided with a clamping ring inside, and the size of the clamping ring corresponds to that of the isolation ring. This step positions the second filter tube by setting the clamping ring, which prevents the second filter tube from sliding inside the filter tube. At the same time, it ensures that the water passes through the surface pores of the second filter tube, which helps to improve the water impurity filtration effect of the device and prevents the first filter tube from being blocked by large impurities.

[0009] Preferably, a limiting ring is fixed to the side wall of the threaded rod, and the size of the limiting ring corresponds to that of the fixing block. This step restricts the movement of the cleaning roller by setting the limiting ring, thereby preventing the motor from disengaging, enhancing the stability and practicality of the device, and helping to extend the service life of the device.

[0010] Preferably, a limiting block is fixedly connected to the side wall of the isolation ring; a limiting rod is fixedly connected to the side wall of the cleaning roller, and the limiting rod is sized to correspond to the limiting block. This step restricts the movement posture of the cleaning roller by setting the limiting rod and the limiting block, thereby preventing the cleaning roller from tilting during movement and daily operation, improving the stability of the device, and helping to extend the service life of the device.

[0011] Preferably, a sealing ring is fixedly connected to the bottom of the concave flange water inlet pipe and the concave flange drain pipe, and the sealing ring is made of rubber. This step improves the sealing performance of the device by setting a sealing ring to cooperate with the concave flange water inlet pipe and the concave flange drain pipe to perform rotational sealing work, which helps to avoid liquid leakage and reduce safety hazards.

[0012] Preferably, the filter pipe, concave flange water inlet pipe, concave flange drain pipe, and flange are made of stainless steel. This step maintains the stability of the device by using rubber material for the filter pipe, concave flange water inlet pipe, concave flange drain pipe, and flange, avoiding rapid rusting and aging of the device components, which helps reduce the maintenance requirements of the device and extend its service life.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The heat exchanger connection device of this utility model filters water by setting an automatic cleaning filter assembly consisting of a first water filter cylinder, a cleaning roller, a water suction head, a threaded rod, and a motor.

[0015] 2. The heat exchanger connection device of this utility model allows the end of the filter pipe to be opened by setting a flange and a water pump. By setting a second filter cylinder to filter larger impurities, the flexibility and practicality of the device are improved, which facilitates the cleaning of the device components by the staff, reduces the difficulty of device maintenance, helps to shorten the maintenance time, and ensures the normal operation of the heat exchanger.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown, a heat exchanger connection device according to an embodiment of the present invention includes a water filter pipe 1. A concave flange water inlet pipe 2 and a concave flange drain pipe 3 are fixedly connected to the bottom of the water filter pipe 1, and the concave flange water inlet pipe 2 and the concave flange drain pipe 3 are arranged correspondingly. A first water filter cylinder 4 is provided inside the water filter pipe 1, and one end of the first water filter cylinder 4 contacts the inner wall of the water filter pipe 1. An isolation ring 20 is provided at the other end of the first water filter cylinder 4. The isolation ring 20 is fixedly connected to the inner wall of the water filter pipe 1. A fixing block 14 is fixedly connected to the side wall of the water filter pipe 1. A threaded rod 10 is threadedly connected inside the fixing block 14. A cleaning roller 6 is fixedly connected to the end of the threaded rod 10. A cleaning roller 6 is fixedly connected to the side wall of the cleaning roller 6. The device includes a water suction head 8, with multiple suction heads 8 arranged in a linear array; a water suction hole 7 is provided on the side wall of the cleaning roller 6, and the water suction hole 7 is connected to the water suction head 8; a water pump 17 is fixedly connected to the bottom of the filter pipe 1; a motor 12 is provided at the end of the threaded rod 10, and a limit plate 13 is fixedly connected to the side wall of the motor 12; during operation, the operator can connect the heat exchanger and the equipment through the concave flange water inlet pipe 2 and the concave flange drain pipe 3. Whenever liquid passes through this device, the automatic cleaning and filtration assembly composed of the first filter cylinder 4, the cleaning roller 6, the water suction head 8, the threaded rod 10, and the motor 12 can filter the liquid, and can also clean the water. During the automatic cleaning of the filter components, whenever the water pump 17, connected to the bottom of the filter pipe 1 by the water suction pipe 18, is driven, the water pump 17 will absorb liquid from a specific area inside the filter pipe 1. Since the suction hole 7 is located within this area, liquid from another area will enter the cleaning roller 6 through multiple suction heads 8 and be sprayed out through the suction hole 7, ultimately being sucked out by the water pump 17. At this time, the operator can drive the motor 12. Because a limiting plate 13 is fixed to the side wall of the motor 12, and the limiting plate 13 is limited by the fixing block 14, and the threaded rod 10 is threadedly connected to the fixing block 14, the motor 12 is driven... The cleaning roller 6 and multiple suction heads 8 fixed to the side wall of the cleaning roller 6 will rotate and move horizontally at the same time. At the same time, the multiple suction heads 8 will clean the surface filter material of the first water filter cylinder 4. The isolation ring 20 serves to fix the first water filter cylinder 4 and block the liquid. This step filters the water by setting up an automatic cleaning filter assembly consisting of the first water filter cylinder 4, the cleaning roller 6, the suction heads 8, the threaded rod 10, and the motor 12. At the same time, it realizes the self-cleaning of the surface filter material of the first water filter cylinder 4, improves the functionality of the heat exchanger connection device, helps to avoid water impurities clogging the pipes, extends the service life of each pipe, and reduces the maintenance requirements of the device and heat exchanger.

[0026] like Figure 2 and Figure 3 As shown, a flange 15 is fixedly connected to the end of the filter pipe 1; a water pump 17 is installed on the side wall of the flange 15, and bolts are installed between the water pump 17 and the flange 15, with multiple bolts arranged in a circumferential array; a second filter cylinder 5 is installed inside the filter pipe 1, and the size of the second filter cylinder 5 corresponds to that of the isolation ring 20; during operation, in addition to automatically cleaning the filter components, the second filter cylinder 5 installed inside the filter pipe 1 can filter larger water impurities by itself. During the process, whenever water enters the filter pipe 1 from the concave flange water inlet pipe 2, the water will first come into contact with the second filter cylinder 5. At this time, larger impurities are filtered out. The impurities will be blocked by the second filter cartridge 5 and remain inside the filter pipe 1. The operator can periodically remove the bolts between the water pump 17 and the flange 15 to open the end of the filter pipe 1, remove the second filter cartridge 5, or clean the inside of the second filter cartridge 5 and the filter pipe 1. This step, by setting the flange 15 and the water pump 17, allows the end of the filter pipe 1 to be opened. By setting the second filter cartridge 5 to filter larger impurities, the flexibility and practicality of the device are improved. This provides convenience for the operator to clean the device components, reduces the difficulty of device maintenance, helps to shorten the maintenance time, and ensures the normal operation of the heat exchanger.

[0027] like Figure 2 As shown, a clamping ring 16 is provided inside the water filter pipe 1, and the size of the clamping ring 16 corresponds to that of the isolation ring 20. During operation, the clamping ring 16, which corresponds to the size of the isolation ring 20, is in close contact between the water pump 17 and the second water filter cylinder 5. Whenever water enters the water filter pipe 1 through the concave flange water inlet pipe 2, the water is blocked by the clamping ring 16 and can only pass through the surface pores of the second water filter cylinder 5. This step, by setting the clamping ring 16 to position the second water filter cylinder 5, prevents the second water filter cylinder 5 from sliding inside the water filter pipe 1, and ensures that the water passes through the surface pores of the second water filter cylinder 5, which is beneficial to improving the water impurity filtration effect of the device and preventing the first water filter cylinder 4 from being blocked by large-sized impurities.

[0028] like Figure 4 As shown, a limiting ring 11 is fixedly connected to the side wall of the threaded rod 10, and the limiting ring 11 is set to correspond to the size of the fixing block 14. During operation, whenever the cleaning roller 6 moves to its limit position under the action of the motor 12, the limiting ring 11 fixed to the side wall of the threaded rod 10 will contact the side wall of the fixing block 14, thereby preventing the cleaning roller 6 from moving further. This step, by setting the limiting ring 11 to restrict the movement of the cleaning roller 6, prevents the motor 12 from disengaging, enhances the stability and practicality of the device, and helps to extend the service life of the device.

[0029] like Figure 5As shown, a limiting block 21 is fixedly connected to the side wall of the isolation ring 20; a limiting rod 9 is fixedly connected to the side wall of the cleaning roller 6, and the limiting rod 9 is set to correspond to the size of the limiting block 21; during operation, whenever the cleaning roller 6 moves under the action of the motor 12, the limiting rod 9 fixed to the end of the cleaning roller 6 will move under the restriction of the limiting block 21; this step restricts the movement posture of the cleaning roller 6 by setting the limiting rod 9 and the limiting block 21, thereby preventing the cleaning roller 6 from tilting during movement and daily operation, improving the stability of the device, and helping to extend the service life of the device.

[0030] like Figure 2 As shown, sealing rings 19 are fixedly connected to the bottom of the concave flange water inlet pipe 2 and the concave flange drain pipe 3, and the sealing rings 19 are made of rubber. During operation, the two rubber sealing rings 19 are fixedly connected to the surface grooves of the concave flange water inlet pipe 2 and the concave flange drain pipe 3, respectively. Whenever the concave flange water inlet pipe 2 and the concave flange drain pipe 3 are connected to the corresponding convex disc, the sealing rings 19 can fill the gap between them by deforming under force. This step improves the sealing performance of the device by setting the sealing rings 19 to cooperate with the concave flange water inlet pipe 2 and the concave flange drain pipe 3 to perform rotational sealing, which helps to avoid liquid leakage and reduce safety hazards.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the filter pipe 1, concave flange water inlet pipe 2, concave flange drain pipe 3, and flange 15 are made of stainless steel. During operation, the stainless steel materials of the filter pipe 1, concave flange water inlet pipe 2, concave flange drain pipe 3, and flange 15 can maintain a smooth surface for a longer period of time, thus maintaining the structural strength of the device. This step, by using rubber materials for the filter pipe 1, concave flange water inlet pipe 2, concave flange drain pipe 3, and flange 15, maintains the stability of the device, prevents the components from rusting and aging quickly, and helps reduce the maintenance requirements of the device and extend its service life.

[0032] During operation, the operator can connect the heat exchanger and equipment via the concave flange water inlet pipe 2 and the concave flange drain pipe 3. Whenever liquid passes through this device, the automatic cleaning filter assembly, composed of the first filter cylinder 4, cleaning roller 6, suction head 8, threaded rod 10, and motor 12, filters the liquid and automatically cleans the filtered material. During the cleaning process of the automatic cleaning filter assembly, whenever the water pump 17, connected to the bottom of the filter pipe 1 by the suction pipe 18, is driven, the water pump 17 will absorb liquid from a specific area inside the filter pipe 1. Since the suction hole 7 is located within this area, liquid from another area will enter the cleaning roller 6 through multiple suction heads 8 and be sprayed out through the suction hole 7, ultimately being drawn out by the water pump 17. At this time, the operation... A person can drive the motor 12. Since a limiting plate 13 is fixed to the side wall of the motor 12, and the limiting plate 13 is limited by the fixing block 14, and the threaded rod 10 is threadedly connected to the fixing block 14, with the drive of the motor 12, the cleaning roller 6 and the multiple suction heads 8 fixed to the side wall of the cleaning roller 6 will rotate and move horizontally at the same time. At the same time, the multiple suction heads 8 will clean the surface filter material of the first filter cylinder 4. The isolation ring 20 serves to fix the first filter cylinder 4 and block the liquid. In addition to automatically cleaning the filter components, the second filter cylinder 5 set inside the filter pipe 1 can filter larger water impurities by itself. During the process, whenever water enters the filter pipe 1 from the concave flange water inlet pipe 2, The water will first come into contact with the second filter cylinder 5. At this time, larger impurities will be blocked by the second filter cylinder 5 and remain inside the filter pipe 1. The operator can periodically remove the bolts between the water pump 17 and the flange 15 to open the end of the filter pipe 1 and take out the second filter cylinder 5, or clean the inside of the second filter cylinder 5 and the filter pipe 1. The clamping ring 16, which is set according to the size of the isolation ring 20, is in close contact between the water pump 17 and the second filter cylinder 5. Whenever the water enters the filter pipe 1 from the concave flange water inlet pipe 2, the water will be blocked by the clamping ring 16 and can only pass through the surface pores of the second filter cylinder 5. Whenever the cleaning roller 6 moves to the limit position under the action of the motor 12, it is fixed to the side wall of the threaded rod 10. The upper limit ring 11 will contact the side wall of the fixed block 14, thereby preventing the cleaning roller 6 from moving further. Whenever the cleaning roller 6 moves under the action of the motor 12, the limit rod 9 fixed to the end of the cleaning roller 6 will move under the restriction of the limit block 21. Two sealing rings 19 made of rubber are respectively fixed in the surface grooves of the concave flange water inlet pipe 2 and the concave flange drain pipe 3. Whenever the concave flange water inlet pipe 2 and the concave flange drain pipe 3 are connected to the corresponding convex plate, the sealing ring 19 can fill the gap between them by deforming under force. The stainless steel filter pipe 1, concave flange water inlet pipe 2, concave flange drain pipe 3, and flange 15 can maintain a smooth surface for a long time and maintain the structural strength of the device.
