During heat recovery, impurities easily clog the pipes, affecting the normal flow of subsequent air. Furthermore, dust adheres to the surface of the heat recovery pipes, impacting the continued effectiveness of heat recovery. Therefore, a new heat recovery device for thermal power engineering is needed to address this problem. Utility Model Content

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes the cooperation between a filter screen and cleaning components located inside the top base. When the airflow reaches the filter screen, the filter screen assists in filtering impurities in the airflow. After filtration, some impurities enter the collection seat. Simultaneously, the airflow drives the drive fan to rotate, which in turn drives the connecting rod to rotate, causing the scraping brush to rotate. This allows the scraping brush to adhere to the top of the filter screen, effectively cleaning the impurities on the top of the filter screen. During operation, this ensures that impurities on the filter screen are effectively cleaned, minimizing the risk of impurities in the hot air clogging the pipes or adhering to the pipe surface, thus affecting subsequent heat exchange.

[0017] This utility model, through its detachable plug-in box and collection base, allows for convenient and effective replacement of the collection base during operation, and enables effective collection and containment of impurities after a period of use.

[0018] This invention utilizes a heat dissipation component mounted on a connecting pipe. Heat from the airflow reaches the heat dissipation pipe, and some of the heat is conducted to the heat dissipation fins. At this time, liquid enters through the bottom water exchange pipe and is poured into the cavity inside the recovery cylinder. The liquid enters the heat dissipation fins through the water guide hole, and some of the liquid enters the heat dissipation pipe, thus completing the overall heat conduction treatment of the heat dissipation component. The extended heat dissipation component can improve heat exchange efficiency and ensure the smooth operation of subsequent work. Attached Figure Description

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a heat recovery device for thermal power engineering, such as... Figure 1 , Figure 2 and Figure 3 As shown, the heat recovery device for thermal power engineering includes a recovery cylinder 1, which is hollow inside to form a cavity. A connecting pipe 12 is fixed in a spiral shape inside the cavity. A top seat 2 protrudes from the top of the recovery cylinder 1. The top seat 2 is hollow inside to form a cleaning chamber. A funnel-shaped filter screen 14 is fixed near the top of the cleaning chamber. A cleaning assembly 15 is installed on the filter screen 14. The cleaning assembly 15 includes a fixing frame fixed to the inner side of the filter screen 14. A connecting rod 153 is installed through the fixing frame. A drive fan 152 is fixed at the bottom of the 153. The top of the connecting rod 153 extends out of the filter screen 14. A scraping brush 151 is fixed at one end of the connecting rod 153 extending out of the filter screen 14. The scraping brush 151 rotates and scrapes the top of the filter screen 14. A plug box 4 is inserted and installed on the top seat 2 corresponding to the bottom of the filter screen 14. A collection seat 5 is installed on the plug box 4. A first installation pipe 3 is installed on the top of the top seat 2 and the bottom of the recycling cylinder 1. A water replacement pipe 11 is horizontally installed on the side of the recycling cylinder 1.

[0028] Through the cooperation between the filter screen 14 and the cleaning component 15 set inside the top seat 2, when the airflow reaches the filter screen 14, the filter screen 14 performs auxiliary filtration of impurities in the airflow. After filtration, some impurities enter the collection seat 5. At the same time, the airflow drives the drive fan 152 to rotate as a whole. When the drive fan 152 rotates, it drives the connecting rod 153 to rotate as a whole, thereby causing the scraping brush 151 to rotate as a whole. This causes the scraping brush 151 to adhere to the top of the filter screen 14, thereby effectively cleaning the impurities on the top of the filter screen 14. During operation, this ensures that the impurities on the filter screen 14 can be effectively cleaned, and minimizes the occurrence of problems such as impurities in the hot air clogging the pipes and adhering to the pipe surface, affecting subsequent heat exchange.

[0029] like Figure 1 , Figure 2 and Figure 4As shown, a slot for the collection seat 5 is provided on the side of the top seat 2. The outer edge of the slot and both ends of the insertion box 4 are provided with fixing ears 6. The fixing ears 6 are symmetrically provided with through holes. The through holes are connected and fixed by fixing components 7. The fixing components 7 include insertion posts 8. A screw 9 is threaded on the insertion post 8. The insertion post 8 is symmetrically provided with a trumpet-shaped receiving opening. A positioning ball 10 is placed in the receiving opening. The bottom of the screw 9 is conical. The screw 9 and the positioning ball 10 are squeezed together. A knob 91 is provided at the top of the screw 9.

[0030] By inserting the fixed component 7 into the through hole and inserting the positioning pin 81 into the positioning hole 61, the knob 91 is rotated clockwise, which drives the lead screw 9 to rotate as a whole. The threaded engagement between the plug pin 8 and the lead screw 9 causes the lead screw 9 to move as a whole and the positioning ball 10 to be squeezed out as a whole. This causes the positioning ball 10 to be squeezed into the through hole of a fixed ear 6, thereby completing the overall positioning and fastening of the plug box 4. This allows for convenient and quick assembly and disassembly of the plug box 4 and the collection seat 5 during operation.

[0031] A protruding disc is provided at the outer edge of one end of the aforementioned plug-in post 8, and a positioning post 81 is provided on the inner side of the protruding disc. A positioning hole 61 is drilled below the corresponding through hole on the fixing lug 6, and the positioning hole 61 and the positioning post 81 are inserted into each other. Through the cooperation between the positioning post 81 and the positioning hole 61, the position of the plug-in post 8 can be effectively determined during installation, ensuring that the plug-in post 8 will not rotate during adjustment.

[0032] like Figure 1 and Figure 5 As shown, a heat dissipation component 13 for auxiliary heat dissipation is installed on the connecting pipe 12. Several heat dissipation components 13 are provided and are equidistantly arranged on the connecting pipe 12. The heat dissipation component 13 includes a heat dissipation pipe 131 that runs horizontally through the connecting pipe 12. Both ends of the heat dissipation pipe 131 are fixed with heat dissipation fins 132. Water guide holes 133 are drilled on the outer side of the heat dissipation fins 132. The heat dissipation pipe 131 is hollow inside.

[0033] Through the heat dissipation component 13 installed on the connecting pipe 12, the heat in the airflow reaches the heat dissipation pipe 131, and some of the heat is conducted to the heat dissipation fins 132. At this time, the liquid enters through the bottom water exchange pipe 11 and is poured into the cavity inside the recovery cylinder 1. The liquid enters the heat dissipation fins 132 through the water guide hole 133, and some of the liquid enters the heat dissipation pipe 131, thereby completing the overall heat conduction treatment of the heat dissipation component 13. Through the extended heat dissipation component 13, the heat exchange efficiency can be improved, ensuring the smooth progress of subsequent work.

[0034] Working principle:

[0035] Before operation, insert the collection seat 5 into the slot, make the two fixing ears 6 fit together, insert the fixing component 7 into the through hole, and insert the positioning pin 81 into the positioning hole 61. Turn the knob 91 clockwise, and the knob 91 will drive the lead screw 9 to rotate as a whole. The threaded engagement between the insertion pin 8 and the lead screw 9 will cause the lead screw 9 to move as a whole and the positioning ball 10 to be squeezed out as a whole. This will cause the positioning ball 10 to be squeezed into the through hole of one of the fixing ears 6, thus completing the overall positioning and fastening of the insertion box 4.

[0036] The hot air pipe is installed at the first installation pipe 3, and the water pipe is connected to the water replacement pipe 11. The hot air flows through the first installation pipe 3, passes through the top seat 2, and enters the connecting pipe 12. When the airflow reaches the filter screen 14, the filter screen 14 performs auxiliary filtration of impurities in the airflow. After filtration, some impurities enter the collection seat 5. At the same time, the airflow drives the transmission fan 152 to rotate as a whole. When the transmission fan 152 rotates, it drives the connecting rod 153 to rotate as a whole, thereby causing the scraping brush 151 to rotate as a whole. This causes the scraping brush 151 to adhere to the top of the filter screen 14, thereby effectively cleaning the impurities on the top of the filter screen 14.

[0037] The heat in the airflow reaches the heat dissipation pipe 131 and conducts some of the heat to the heat dissipation fins 132. At this time, the liquid enters through the bottom water exchange pipe 11 and is poured into the cavity inside the recovery cylinder 1. The liquid enters the heat dissipation fins 132 through the water guide hole 133 and conducts some of the liquid into the heat dissipation pipe 131, thereby completing the overall heat conduction treatment of the heat dissipation component 13.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
