Description

Technical Field

[0001] This utility model relates to the field of cooler technology, and in particular to a cooler with a waste heat recovery structure. Background Technology

[0002] A cooler is a device that uses water or air as a coolant to remove heat from a fluid. It is a heat exchange device widely used in industries such as metallurgy, chemical industry, energy, transportation, light industry, and food. There are many types of coolers, including indirect cooling systems, spray cooling systems, jacketed cooling systems, and coil cooling systems.

[0003] To address this issue, patent CN221425435U discloses a cooler capable of waste heat recovery, comprising a housing. A water inlet pipe is fixedly installed on one side of the housing, and a drain pipe is fixedly installed on the top of one side of the housing. A heat-conducting pipe is fixedly installed on one side of the water inlet pipe, and a return pipe is fixedly installed on one side of the drain pipe. One end of the return pipe is fixedly connected to the water inlet pipe, and a thermometer is fixedly installed on one side of the return pipe. Through the structural design of the water inlet pipe, drain pipe, and heat-conducting pipe, a water circulation heating function is achieved, solving the problem of poor waste heat recovery caused by poor fluidity. Water can be circulated through the heat-conducting pipe, continuously replacing the cooling water for waste heat recovery, avoiding the problem of poor waste heat recovery as the cooling water temperature increases. The return pipe allows the water in the heat-conducting pipe to be circulated and heated for subsequent use.

[0004] Existing coolers with waste heat recovery structures are difficult to clean thoroughly inside during use. Dust and other impurities adhere to the inside of the cooler, affecting the efficiency of waste heat exchange. Utility Model Content

[0005] The purpose of this invention is to provide a cooler with a waste heat recovery structure to solve the problem that existing coolers with waste heat recovery structures are difficult to thoroughly clean the interior of the cooler.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cooler with a waste heat recovery structure, comprising a cooler body, support frames installed on both sides of the bottom end of the cooler body, a drain port installed at the bottom end of the cooler body, an air inlet and an air outlet installed on both sides of the cooler body, a filter screen installed inside the air inlet, a cleaning structure provided on the filter screen, an auxiliary structure provided at the bottom end of the air inlet, a heat exchange tube installed inside the cooler body, a liquid inlet and a liquid outlet installed at both ends of the heat exchange tube, a flushing mechanism provided on the outside of the heat exchange tube, the flushing mechanism comprising a large gear installed on one side inside the cooler body, a small gear installed below the large gear, a drive motor installed on one side of the small gear, a spray pipe installed at one end of one side of the large gear, spray nozzles evenly installed on the spray pipe, a turntable installed at one end of the spray pipe, and a water inlet pipe connected to the turntable.

[0007] Preferably, the auxiliary structure includes a chute, a fixing frame, a trash box, a slider, and a through groove. The fixing frame is installed at the bottom of the air inlet, and a through groove is opened at the top of the fixing frame. The trash box is installed inside the fixing frame, and sliders are installed on both sides of the trash box. The chute is opened on the inner wall of the fixing frame.

[0008] The above structure allows dust that falls off the filter screen to be collected for centralized processing.

[0009] Preferably, the slider and the groove cooperate to form a sliding structure.

[0010] The above structure makes it easy to pull the trash can.

[0011] Preferably, a valve is installed on the water inlet pipe, and one end of the water inlet pipe is connected to one end of the liquid outlet.

[0012] With the above structure, when the valve is opened, the water discharged from the outlet can enter the spray pipe through the inlet pipe.

[0013] Preferably, a limiting groove is formed on the inner wall of both sides of the cooler body, and the large gear and turntable are inserted into the limiting groove and form a sliding connection with it.

[0014] Through the above structure, the limiting groove can play a certain limiting role for the large gear and turntable, thereby improving their stability during rotation.

[0015] Preferably, the cleaning structure includes a brush, a first rod, a second rod, and a telescopic spring. The second rod is mounted on one side of the large gear, and a telescopic spring is installed inside the second rod. The first rod is mounted on one side of the telescopic spring, and the brush is mounted on one side of the first rod.

[0016] The above structure allows for the cleaning of the filter screen, preventing it from becoming clogged.

[0017] Preferably, the other side of the first rod is disposed in the second rod, and the first rod and the telescopic spring form a telescopic structure.

[0018] With the above structure, the telescopic spring can act to make contact between the brush and the filter screen.

[0019] The present invention provides a cooler with a waste heat recovery structure, the advantages of which are:

[0020] The flushing mechanism can thoroughly flush the inner wall of the cooler and the heat exchange tubes to prevent dust and other impurities from adhering to the inside of the cooler and affecting the efficiency of the remaining heat exchange. The cleaning structure can clean the filter screen to prevent it from becoming clogged. The auxiliary structure can collect the dust that falls off the filter screen for centralized treatment.

[0021] By opening the valve of the inlet pipe through the flushing mechanism, the water discharged from the outlet enters the spray pipe and is sprayed out through the nozzle. The motor drives the motor to rotate in both directions, and the small gear drives the large gear to rotate. The spray pipe rotates in the direction of the limiting groove, so as to achieve the purpose of flushing the inner wall of the cooler and the heat exchange tube in all directions.

[0022] Through the cleaning structure, the second rod drives the first rod to rotate, the extension spring acts to make the brush contact the filter screen, and when the large gear rotates, the brush rotates, thus achieving the purpose of cleaning the filter screen and preventing it from becoming clogged.

[0023] With the help of the auxiliary structure, the dust cleaned off the filter screen falls into the dust box through the channel, thus achieving the purpose of dust collection. Pulling the dust box causes the slider to exit the channel, allowing the dust box to be pulled out for cleaning and replacement. Attached Figure Description
