Description

Technical Field

[0001] This utility model relates to the technical field of thermal storage and peak shaving devices, and in particular to a circulating device for thermal storage and peak shaving. Background Technology

[0002] Thermal energy storage for peak shaving refers to regulating the load demand of the power grid by storing and releasing thermal energy, thereby balancing power supply and demand and ensuring the stable operation of the power system. Thermal energy storage peak shaving technologies mainly include two methods: high-temperature thermal energy storage power generation for peak shaving and deep peak shaving using extraction back-pressure units based on molten salt thermal energy storage systems.

[0003] When a thermal energy storage and peak-shaving device releases heat energy, the hot air in the heat energy is accompanied by flue gas. The flue gas in the hot air needs to be filtered. Over time, dust will accumulate in the filter screen, resulting in poor filtration efficiency. At the same time, the flue gas will adhere to the inner wall of the thermal energy storage circulation device, which needs to be dealt with in time. However, the traditional manual cleaning method is inefficient, and the equipment cannot be started during the cleaning process to avoid personnel danger and delay power supply balancing operations. Therefore, a circulation device for thermal energy storage and peak shaving is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circulating device for thermal storage and peak shaving.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, the dust removal mechanism includes multiple air outlets opened on the bottom wall of the guide pipe, a hollow frame is fixedly connected to the inner wall of the peak-shaving box, and an electric reciprocating screw is rotatably connected to the inner wall of the hollow frame.

[0008] Preferably, a fan blade is fixedly connected to the surface of the electric reciprocating screw, and a brush is fixedly connected to the upper surface of the fan blade.

[0009] Preferably, a pair of guide rods are fixedly connected to the upper surface of the hollow frame, and the same scraper is slidably connected to the surface of the pair of guide rods, with the surface of the scraper in close contact with the inner wall of the peak-shaving box.

[0010] Preferably, the lower surface of the scraper is fixedly connected with an anti-stick coating, the inner wall of the scraper is fixedly connected with a filter screen, and the surface of the filter screen is provided with clearance holes. The position of the clearance holes corresponds to the position of the electric drive reciprocating lead screw, and the size of the clearance holes is adapted to the electric drive reciprocating lead screw.

[0011] Preferably, a guide plate is fixedly connected to the lower surface of the scraper, a U-shaped plate is rotatably connected to the surface of the guide plate, and a pair of convex shafts are fixedly connected to the surface of the U-shaped plate, with one end of the convex shafts extending to the inner wall of the electric drive reciprocating lead screw.

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

[0014] The electric reciprocating screw rotates through a pair of cams, causing the guide plate to move and drive the connected scraper to move up and down. The scraper descends and scrapes away the dust adhering to the inner wall of the peak-shaving box. The fan blades rotate, driving multiple brushes mounted on the surface to rotate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A circulating device for heat storage and peak shaving includes a peak shaving box 1. An air inlet pipe 3 and an air outlet pipe 4 are fixedly connected to the inner wall of the peak shaving box 1. A garbage box 5 is slidably connected to the inner wall of the peak shaving box 1. A controller 2 is fixedly connected to the surface of the peak shaving box 1. A guide pipe 6 is fixedly connected to one end of the air inlet pipe 3. A dust removal mechanism is provided on the inner bottom wall of the guide pipe 6.

[0024] By setting up a garbage box 5, the smoke and dust swept down from the filter screen 9 and the inner wall of the peak-shaving box 1 are collected. By setting up a controller 2, the rotation of the electric drive reciprocating screw 12 is controlled. By setting up a guide pipe 6, the hot air sent out by the air inlet pipe 3 is guided to the bottom of the fan blade 18 for discharge. By setting up a dust removal mechanism, automatic dust removal and collection operations are carried out.

[0025] In this utility model, the dust removal mechanism includes multiple air outlets 13 opened on the bottom wall of the guide pipe 6, and a hollow frame 10 is fixedly connected to the inner wall of the peak-shaving box 1. An electric reciprocating screw 12 is rotatably connected to the inner wall of the hollow frame 10.

[0026] Hot air from the guide pipe 6 is discharged through the air outlet 13. The electric drive reciprocating screw 12 is installed and supported by the hollow frame 10, and the electric drive reciprocating screw 12 provides the driving force for rotation.

[0027] In this utility model, a fan blade 18 is fixedly connected to the surface of the electric drive reciprocating lead screw 12, and a brush 14 is fixedly connected to the upper surface of the fan blade 18.

[0028] By setting the fan blades 18, the hot air in the peak-shaving box 1 is transported and smoothly filtered and discharged into the air outlet duct 4. By setting the brush 14, when the filter screen 9 comes into contact with the brush 14, a cleaning operation is performed to prevent the filter screen 9 from clogging.

[0029] In this utility model, a pair of guide rods 16 are fixedly connected to the upper surface of the hollow frame 10, and the same scraper 8 is slidably connected to the surface of the pair of guide rods 16. The surface of the scraper 8 is in close contact with the inner wall of the peak-shaving box 1.

[0030] By setting the guide rod 16, the scraper 8 is kept in a stable sliding position. The scraper 8 is used to scrape away the dust adhering to the inner wall of the peak shaving box 1.

[0031] In this utility model, the lower surface of the scraper 8 is fixedly connected with an anti-stick coating 11, and the inner wall of the scraper 8 is fixedly connected with a filter screen 9. The surface of the filter screen 9 is provided with a clearance hole 20, the position of the clearance hole 20 corresponds to the position of the electric drive reciprocating screw 12, and the size of the clearance hole 20 is adapted to the electric drive reciprocating screw 12.

[0032] By setting an anti-stick coating 11, smoke and dust are prevented from sticking to the lower surface of the scraper 8. By setting a filter screen 9, smoke and dust are intercepted and filtered. By setting a clearance hole 20, the filter screen 9 is prevented from hitting the electric drive reciprocating screw 12 when it moves up and down.

[0033] In this utility model, a guide plate 17 is fixedly connected to the lower surface of the scraper 8, a U-shaped plate 19 is rotatably connected to the surface of the guide plate 17, and a pair of convex shafts 21 are fixedly connected to the surface of the U-shaped plate 19. One end of the convex shaft 21 extends to the inner wall of the electric drive reciprocating screw 12.

[0034] By setting the guide plate 17 and installing the U-shaped plate 19, and by setting the U-shaped plate 19 and installing a pair of convex shafts 21, the scraper 8 as a whole moves up and down reciprocally under the action of the pair of convex shafts 21.

[0035] In this utility model, a stabilizing plate 7 is fixedly connected to the inner top wall of the peak-shaving box 1, the top end of the electric drive reciprocating screw 12 is rotatably connected to the lower surface of the stabilizing plate 7, and a push-pull plate 15 is fixedly connected to the surface of the garbage box 5.

[0036] By setting a stabilizing plate 7, the rotation of the top end of the electric drive reciprocating screw 12 is kept stable. By setting a push-pull plate 15, the operator can easily pull the garbage box 5 out of the peak shaving box 1.

[0037] Working principle: When supplying hot air to the peak-shaving box 1 through the air inlet pipe 3, the controller 2 is activated. The controller 2 controls the electric reciprocating screw 12 to rotate. The rotation of the electric reciprocating screw 12 drives the U-shaped plate 19 to be stressed through a pair of convex shafts 21, causing the guide plate 17 to move under the guidance of the guide rod 16. The movement of the guide plate 17 drives the connected scraper 8 to move up and down reciprocally. The scraper 8 descends and scrapes away the dust adhering to the inner wall of the peak-shaving box 1. When the filter screen 9 descends and its surface contacts the multiple brushes 14, the electric reciprocating screw 12 rotates simultaneously, driving the fan... When the blade 18 rotates, it drives multiple brushes 14 mounted on the surface to rotate, achieving a cleaning effect. The function of the rotating blade 18 is to better push the hot air discharged from the multiple air outlets 13 to be filtered and transported by the filter screen 9. When the filter screen 9 descends, the clearance hole 20 and the electric drive reciprocating screw 12 make space clearance to prevent the filter screen 9 from hitting the surface of the electric drive reciprocating screw 12. The dust falls into the trash box 5 under its own gravity. When it is necessary to collect the ash in the trash box 5, the push-pull plate 15 is pulled to clean the dust in the trash box 5.
