Energy-saving cooling device with waste heat recovery

Abstract

This utility model discloses an energy-saving cooling device with waste heat recovery, including a coolant tank, a filter plate, and a filter assembly. External coolant is transported into the coolant tank through an inlet. The filter plate filters the coolant, intercepting small impurities and reducing pipe blockage. When replacing the filter plate, pulling the pull plate outward causes the sliding rod to move outward, which in turn moves the locking block outward. This compresses the spring, separating the locking block from one side of the filter plate. The filter plate is then pulled out from the top of the coolant tank along the slide groove for easy cleaning and replacement. The filter plate is then inserted into the coolant tank from the top along the slide groove. By releasing the pull plate, the locking block is reset by the spring, causing it to abut against the filter plate and securely fix the filter plate inside the coolant tank.

Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery and energy saving, and in particular to an energy-saving cooling device with waste heat recovery. Background Technology

[0002] In waste battery processing, cooling devices play a crucial role in cooling gases, ensuring smooth processing while also promoting environmental protection and resource recycling. The gases generated during the roasting, pyrolysis, and smelting processes of waste batteries are at high temperatures; for example, the exhaust gas from high-temperature roasting can reach 300-800℃. Subsequent purification equipment, such as desulfurization, denitrification, and dust removal, can only operate efficiently within a suitable temperature range. Cooling devices lower the high-temperature gases to a suitable temperature, allowing the purifying agents to fully contact and react with the pollutants, improving purification efficiency and ensuring that the exhaust gas meets emission standards.

[0003] The high-temperature gas generated during the waste battery processing is transported through pipelines to the hot-side inlet of the heat exchanger in the cooling device. Inside the heat exchanger, the high-temperature gas comes into contact with the low-temperature coolant. According to the principle of heat transfer, heat is transferred from the high-temperature gas to the coolant, the gas temperature decreases, and the coolant temperature increases. The cooled coolant is then pumped back to the heat exchanger by a circulation pump to continue participating in the cooling process of the high-temperature gas.

[0004] In the waste battery processing environment, the gas cooling process may introduce impurities such as metal shavings, dust, and oxide particles due to pipeline corrosion, equipment aging, or material leakage. These impurities will accumulate in the tank with the coolant and will be directly sucked in by the circulating pump. They will flow through components such as heat exchangers, valves, and pipes with the coolant, clogging the flow channels, reducing heat exchange efficiency, and affecting the continuous operation of the cooling device. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5This utility model provides an embodiment of an energy-saving cooling device with waste heat recovery, including a coolant tank 101, a filter plate 104, and a filter assembly. An inlet 102 is fixedly connected to the top of the coolant tank 101. A filter assembly is installed inside the coolant tank 101. A sliding groove 103 is fixedly connected inside the coolant tank 101, and the filter plate 104 is slidably connected inside the sliding groove 103. A locking block 105 is slidably connected inside the sliding groove 103, and a sliding rod 106 is fixedly connected to the side of the locking block 105. A through groove is opened on the outer side of the coolant tank 101, and a fixing plate 107 is fixedly connected inside the through groove. The sliding rod 106 passes through the fixing plate 107 to the outer side of the coolant tank 101. A pull plate 108 is fixedly connected to the outer side of the sliding rod 106. A spring 109 is fixedly connected to one side of the locking block 105 located outside the sliding rod 106, and the other side of the spring 109 is fixedly connected to the fixing plate 107. The coolant is cooled by the inlet 102. The coolant is transported into the coolant tank 101. The filter plate 104 filters the coolant, intercepting small impurities and reducing pipe blockage. When replacing the filter plate 104, the pull plate 108 is pulled outward. The pull plate 108 moves outward, causing the sliding rod 106 to move outward. The sliding rod 106 moves outward, causing the locking block 105 to move outward, thus compressing the spring 109 and causing the locking block 105 to engage with the filter plate 104. The filter plate 104 is pulled out from the top of the coolant tank 101 along the slide groove 103 to facilitate cleaning and replacement. The filter plate 104 is then inserted into the coolant tank 101 from the top along the slide groove 103. By releasing the pull plate 108, the locking block 105 is reset by the action of the spring 109, so that the locking block 105 abuts against the filter plate 104, thus more stably fixing the filter plate 104 into the coolant tank 101.

[0022] Please see Figures 1-3In this embodiment, a connecting pipe 110 is fixedly connected to one side of the coolant tank 101, a circulating pump 111 is fixedly connected to the other side of the connecting pipe 110, a connecting pipe 212 is fixedly connected to the other side of the circulating pump 111, a heat exchanger 201 is fixedly connected to the other side of the connecting pipe 212, a connecting pipe 302 is fixedly connected to the other side of the heat exchanger 201, a heat pump 203 is fixedly connected to the other side of the connecting pipe 302, and a connecting pipe 404 is fixedly connected to the other side of the heat pump 203. The connecting pipe 404 is fixedly connected to the coolant tank 101. The coolant in the coolant tank 101 is drawn by the circulation pump 111 through the first connecting pipe 110. The circulation pump 111 provides power to pressurize the coolant and then delivers it to the heat exchanger 201 through the second connecting pipe 112. In the heat exchanger 201, the coolant exchanges heat with the high-temperature gas to be processed. The coolant absorbs the heat of the gas, causing the gas temperature to drop and its own temperature to rise. The high-temperature coolant after absorbing heat enters the heat pump 203 through the third connecting pipe 202. The heat pump 203 extracts the residual heat from the coolant through the refrigeration cycle. After the coolant temperature drops, it flows back to the coolant tank 101 through the fourth connecting pipe 204.

[0023] Please see Figures 2-5 In this embodiment, a connecting pipe 205 is fixedly connected to one side of the heat exchanger 201, and a filter box 206 is fixedly connected to one side of the connecting pipe 205. An air inlet 207 is fixedly connected to one side of the filter box 206. Vertical plates 301 are fixedly connected to both sides of the filter box 206. A spring 302 is fixedly connected to one side of the vertical plate 301, and a filter screen 303 is fixedly connected to the other side of the spring 302. A rotating rod 304 is provided inside the filter box 206, and a hand crank 305 is provided outside the filter box 206. The hand crank 305 is rotatably connected to the rotating rod 304. A cam 306 is fixedly connected above the rotating rod 304. A collection groove 307 is slidably connected inside the filter box 206. The gas to be cooled enters the filter box 206 through the air inlet 207. Inside the filter box 206, after filtration, the gas enters the heat exchanger 201 through connecting pipe 205. Inside the heat exchanger 201, the gas exchanges heat with the low-temperature coolant. The cooled gas is discharged from the other end of the heat exchanger 201. The gas can be filtered through the filter screen 303 to intercept impurities in the gas. By turning the hand crank 305, the rotating rod 304 is rotated. The rotation of the rotating rod 304 drives the cam 306 to rotate. The protruding part of the cam 306 periodically squeezes the filter screen 303, causing the filter screen 303 to vibrate back and forth under the elastic force of the spring 302. This shakes off the impurities remaining on the filter screen 303 into the collection tank 307, preventing the filter screen 303 from clogging. The collection tank 307 can be slid out along the inner wall of the filter box 206 for easy periodic cleaning of impurities.

[0024] During operation, the gas to be cooled enters the filter box 206 through the inlet 207. After filtration, it enters the heat exchanger 201 through the connecting pipe 205. Inside the heat exchanger 201, the gas exchanges heat with the low-temperature coolant. The cooled gas is discharged from the other end of the heat exchanger 201. The gas is filtered through the filter screen 303 to intercept impurities. By turning the hand crank 305, the rotating rod 304 is rotated, which in turn drives the cam 306 to rotate. The protruding part of the cam 306 periodically squeezes the filter screen 303, causing the filter screen 303 to vibrate back and forth under the elastic force of the spring 302. This shakes off the impurities remaining on the filter screen 303 and onto the collection tank 30. In section 7, to prevent the filter screen 303 from clogging, the collection tank 307 can be slidably pulled out along the inner wall of the filter box 206 for easy periodic cleaning of impurities. The coolant in the coolant tank 101 is drawn by the circulation pump 111 through the connecting pipe 110. The circulation pump 111 provides power to pressurize the coolant and then delivers it to the heat exchanger 201 through the connecting pipe 212. In the heat exchanger 201, the coolant exchanges heat with the high-temperature gas to be treated. The coolant absorbs the heat of the gas, causing the gas temperature to drop and its own temperature to rise. The high-temperature coolant after absorbing heat enters the heat pump 203 through the connecting pipe 3202. The heat pump 203 extracts the residual heat from the coolant through the refrigeration cycle. After the coolant temperature drops, it flows back to the coolant tank 101 through the connecting pipe 4204.

[0025] Through the above steps, external coolant is transported into the coolant tank 101 through the inlet 102. The filter plate 104 filters the coolant, intercepting small impurities and reducing pipe blockage. When replacing the filter plate 104, pull the pull plate 108 outward. The outward movement of the pull plate 108 moves the sliding rod 106 outward, which in turn moves the locking block 105 outward, thus compressing the spring 109 and causing the locking block 105 to move outward. Separate one side of the filter plate 104 and pull the filter plate 104 out from the top of the coolant tank 101 along the slide groove 103 to facilitate cleaning and replacement of the filter plate 104. Insert the filter plate 104 into the coolant tank 101 from the top along the slide groove 103. By releasing the pull plate 108, the locking block 105 is reset by the action of the spring 109, so that the locking block 105 abuts against the filter plate 104, and more stably fixes the filter plate 104 into the coolant tank 101.
