Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to an energy storage device for the reuse of waste heat from air compressors. Background Technology

[0002] An air compressor is a device used to compress gas. A waste heat recovery heat exchanger is installed in the exhaust pipe of the air compressor. The exhaust hot air exchanges heat with a cooling medium (such as water or air) through the heat exchanger, thereby recovering heat energy. This heat energy can be used in heating systems, hot water systems, or other equipment that requires heat energy. Some waste heat recovery devices use insulated boxes and circulating water tanks to store and utilize the recovered heat energy. For example, the insulated box is placed in the circulating water tank, and the circulating water tank insulates the insulated box, so that the cooling water after heat exchange can reduce the heat dissipation rate, thereby improving the efficiency of waste heat recovery and utilization.

[0003] For example, CN211601653U discloses "An Energy Storage Device for Reusing Waste Heat from an Air Compressor". This device includes a frame, an air compressor frame, a cooler, a water pump, and a support plate. The air compressor frame is installed at the bottom of the frame, and the cooler is installed at the top of the air compressor frame. The support plate is installed at the upper part of the frame, and a heat storage tank is installed at the top of the support plate. A partition is installed inside the heat storage tank, and a storage compartment is provided at the top of the partition. A water storage compartment is provided at the bottom of the partition. An inlet penetrating one side wall of the frame is installed at the upper part of the water storage compartment near the side wall of the water pump. Grooves are evenly spaced inside the storage compartment. This energy storage device for reusing waste heat from an air compressor uses a cooler to absorb the heat generated by the air compressor frame through water inside the connecting pipe, which is then discharged into the water storage compartment. Through water circulation and heat storage, the water inside the storage compartment is heated, facilitating the storage of waste heat generated by the air compressor.

[0004] Although the above-mentioned energy storage devices have certain advantages in waste heat energy storage, they still have certain drawbacks: when using the above-mentioned energy storage devices for waste heat energy storage, the water in the water storage tank needs to be replenished by manually operating the switch when it is used. This method is relatively troublesome, cannot achieve the effect of automatic water replenishment, increases labor costs, and is inconvenient to use. Utility Model Content

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an energy storage device for reusing waste heat from an air compressor, comprising a waste heat utilization device, a water storage tank, an outlet pipe, an inlet pipe, an electric valve, and a control device.

The pressure plate is fixed to the bottom of the connecting rod. The fixing mechanism is located inside the water storage tank and is used to fix the baffle.

[0009] Preferably, the waste heat utilization device includes a shell, an air inlet pipe, an exhaust pipe, a heat exchange pipe, and a water pump. The shell is located outside the water storage tank. The air inlet pipe is connected to the left end of the shell. The exhaust pipe is connected to the left end of the shell. The heat exchange pipe is located at one end of the shell and penetrates the interior of the shell, connecting to the left end of the water storage tank.

[0015] (III) Beneficial Effects

[0016] This utility model provides an energy storage device for the reuse of waste heat from an air compressor. It offers the following advantages: A control device is installed to control the movement of a float plate based on the water level in the storage tank. When the water level rises, the float plate moves upward, causing a pusher block to move. The pusher block then moves a baffle plate, which is fixed in place by the cooperation of a locking block and a locking groove, effectively blocking the water inlet pipe and sealing the inlet. When the water level drops, the float plate moves downward with the support rod, which in turn moves the connecting rod downward. The connecting rod then moves the pressure plate downward, pushing the locking block downward and removing the restriction effect of the locking block in the locking groove. Water then flows back through the baffle and into the storage tank, automatically replenishing the water. This design ensures that the storage tank always contains water, enabling automatic replenishment, eliminating the need for manual operation, and improving the overall performance.

The outer side of 66 is fixedly connected, the pressure plate 68 is fixed to the bottom end of the connecting rod 67, and the fixing mechanism 69 is set inside the water storage tank 2. The fixing mechanism 69 is used to fix the baffle 65. The waste heat utilization device 1 includes a shell 11, an air inlet pipe 12, an exhaust pipe 13, a heat exchange pipe 14 and a water pump 15. The shell 11 is set outside the water storage tank 2. The air inlet pipe 12 is connected to the left end of the shell 11. The exhaust pipe 13 is connected to the left end of the shell 11. The heat exchange pipe 14 is set at one end of the shell 11 and penetrates the shell 15. The interior of 1 is connected to the left end of the water storage tank 2. The water pump 15 is installed on the outside of the heat exchange pipe 14. The float plate 62 is slidably connected to the outside of the fixing rod 61 through the guide key. This setting restricts the position of the float plate 62 and allows the float plate 62 to move along the vertical direction of the fixing rod 61. The top of the push block 63 is arc-shaped. This setting makes it easier and more stable for the push block 63 to push the baffle 65. The top of the fixing block 64 is provided with a groove. This setting allows the fixing block 64 to support the baffle 65.

[0025] Please see Figure 5This utility model provides a technical solution for an energy storage device for the reuse of waste heat from an air compressor: an energy storage device for the reuse of waste heat from an air compressor, the fixing mechanism 69 includes an adjusting groove 691, a locking block 692, a limiting rod 693, a spring 694 and a slot 695. The adjusting groove 691 is opened inside the water storage tank 2, the locking block 692 passes through the interior of the adjusting groove 691, the limiting rod 693 passes through the interior of the locking block 692, and both ends of the limiting rod 693 are fixed inside the adjusting groove 691. The spring 694 is fitted on the outside of the limiting rod 693. The slot 695 is opened on the outside of the baffle 65. The left end face of the locking block 692 is convex and inclined, and tilts upward from left to right. This arrangement allows the baffle 65 to move by pressing the inclined surface of the locking block 692 when rotating. At the same time, the position of the baffle 65 is fixed by the cooperation of the locking block 692 and the slot 695.

[0026] The working principle is as follows:

[0027] First, when in use, connect the heat exchange pipe 14 in the shell 11 to the water storage tank 2, and connect the air inlet pipe 12 to the air compressor, and wait for use;

[0028] Second, when using the water, close the electric valve 5 and replenish the water tank 2 with water through the water inlet pipe 4;

[0029] Third, as the water level rises, the float 62 moves along with the rising water level. When the float 62 moves, it drives the push block 63 to move. When the push block 63 moves, it pushes the baffle 65 to rotate. When the baffle 65 rotates, it rotates around the fixed block 64 as the rotation center. When the baffle 65 rotates, it squeezes the inclined surface of the locking block 692, so that the spring 694 is squeezed along the limiting rod 693. When the locking groove 695 moves in front of the locking block 692 along with the baffle 65, the spring 694 loses its force and releases elastic potential energy to push the locking block 692 to move. The locking block 692 extends into the locking groove 695 to fix the baffle 65, thus completing the fixing effect of the baffle 65 and sealing the water inlet pipe 4.

[0030] Fourth, hot air enters the shell 11 through the exhaust pipe 13, and the water pump 15 is started. The water pump 15 discharges the water in the water storage tank 2 into the heat exchange pipe 14, which comes into contact with the hot air in the shell 11, so that the hot air heats the inside of the heat exchange pipe 14. The heated water flows back into the water storage tank 2 through the heat exchange pipe 14. At this time, the water in the water storage tank 2 is hot water.

[0031] Fifth, when water in the water storage tank 2 is needed, start the electric valve 5. Water in the water storage tank 2 will be discharged from the outlet pipe 3. When the water is discharged, the water level will drop, causing the float 62 to move down. When the float 62 moves down, it will drive the support rod 66 to move down. When the support rod 66 moves down, it will drive the connecting rod 67 to move down. When the connecting rod 67 moves down, it will drive the pressure plate 68 to move down.

[0032] Sixth, when the pressure plate 68 moves down, it pushes the locking block 692 downward, canceling the fixing effect of the locking block 692 in the slot 695, thereby canceling the fixing of the baffle 65. The water flow pushes the baffle 65, opens the baffle 65 and flows into the water storage tank 2, realizing automatic water replenishment.

The power supply is also common knowledge in the field.
