Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying room that facilitates the utilization of waste heat. Background Technology

[0002] A drying room is a device that accelerates the drying of objects by artificially controlling temperature and humidity. It has wide applications in many fields, such as food processing, wood treatment, and industrial production. The core function of a drying room is to remove moisture from objects while maintaining their quality.

[0003] In the prior art, Chinese Patent Publication No. CN222231225U discloses a waste heat utilization drying chamber, including a drying chamber body, an air supply assembly for supplying air to the drying chamber body to dry demolded EPP molded parts, and a heat exchanger for heating the cold air introduced by the air supply assembly into hot air. The heat exchanger has a heat exchanger inlet and a heat exchanger outlet, and is installed on the side wall of the drying chamber body. The air supply assembly is integrally disposed at the heat exchanger inlet. This invention's drying chamber body has its own heat exchanger and air supply assembly, allowing it to utilize waste heat to heat the incoming air without the need for external hot air, effectively reducing operating costs. This invention can effectively utilize various waste heat sources in the production process as heat sources for heat exchange, reducing production costs and improving resource utilization.

[0004] In actual production and use, although this type of waste heat utilization drying room can use the waste heat of the drying room to heat the incoming air and improve the resource utilization rate, this type of waste heat utilization drying room is not equipped with a filtration device. This may result in the air that re-enters the drying room from the heat exchanger containing dust, which may remain on the surface of the items during drying, resulting in poor performance of this device. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a drying room that facilitates the utilization of waste heat, and has a good effect on the utilization of waste heat in the drying room.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a drying room that facilitates waste heat utilization, comprising a drying room, a water tank, a water tower, a door, and an exhaust pipe. A gas collecting hood is fixedly connected to the top of the drying room. A water pump is fixedly connected inside the water tank. A coil is fixedly connected inside the water tower. A pipe is fixedly connected to the outside of the gas collecting hood. The pipe extends into the interior of the water tower and is fixedly connected to one end of the coil. One end of the exhaust pipe extends into the interior of the water tower and is fixedly connected to the other end of the coil. A cylindrical gas hood is fixedly connected to the other end of the exhaust pipe. A water outlet pipe is fixedly connected to the outside of the water tower. A valve hole is opened inside the water outlet pipe. A valve is installed outside the water tower. A stud is fixedly connected to the bottom of the valve, extending into the valve hole. A pulley is installed at the bottom of the door. A water supply pipe is installed outside the water tank. The output end of the water pump is fixedly connected to the water supply pipe, which extends into the interior of the water tower.

[0007] By adopting the above technical solution, workers start the water pump, and the water in the pool flows into the water tower. After the water tower is filled with an appropriate amount of water, the coil is submerged. Workers then turn off the water pump. During the drying process, the high-temperature flue gas in the drying room is collected by the gas collection hood and transported to the inside of the coil through the pipe. During the transportation of the high-temperature flue gas inside the coil, the high temperature in the flue gas is transferred to the wall of the coil, so that the wall of the coil and the water injected into the water tower complete the heat exchange. As the high-temperature flue gas is continuously transported to the inside of the coil, the water injected into the water tower is continuously heated. After the high temperature in the flue gas completes the heat exchange with the water, the water temperature drops and is discharged from the exhaust pipe. When workers need hot water, they open the valve, and the heated water in the water tower flows into the bucket. In this way, the waste heat in the high-temperature flue gas discharged from the drying room during the drying process is reused, reducing energy waste and achieving the best effect of waste heat utilization in the drying room.

[0008] A further feature of this invention is that a cylinder is fixedly connected to the outside of the drying chamber, a top plate is fixedly connected to the outside of the door, and the output end of the cylinder is fixedly connected to the top plate.

[0009] By adopting the above technical solution, the worker starts the cylinder, which drives the top plate to move upward, causing the top plate to move the box door upward, thus realizing the automatic opening of the drying room door.

[0010] A further feature of this invention is that a groove is provided on the outside of the drying chamber, and the pulley is slidably connected to the groove.

[0011] By adopting the above technical solution, when the door is subjected to force, the sliding connection between the pulley and the groove allows the door to move smoothly.

[0012] A further feature of this invention is that a liner is fixedly connected to the outside of the drying chamber, and a slot is formed inside the liner, with the door extending through the slot.

[0013] By adopting the above technical solution, the door passes through the inside of the slot when it is subjected to force, which provides guidance for the vertical movement of the door.

[0014] A further feature of this invention is that a base plate is fixedly connected to the bottom of the drying room, and a pad is fixedly connected to the bottom of the base plate.

[0015] By adopting the above technical solution, the pad and base plate keep the bottom of the drying room away from the ground, preventing moisture from the ground from entering the interior of the drying room.

[0016] A further feature of this invention is that a return air plate is fixedly connected inside the drying room, and the number of return air plates is two.

[0017] By adopting the above technical solution, the two return air plates can effectively convect the airflow inside the drying chamber, thereby improving the efficiency of material drying.

[0018] A further feature of this invention is that a hot air blower is fixedly connected inside the drying room, and the distance between each pair of hot air blowers is equal.

[0019] By adopting the above technical solution, the hot air blower is started, and the hot air blower blows air into the interior of the drying room, making the temperature inside the drying room more uniform.

[0020] A further feature of this invention is that a temperature dial is fixedly connected to the outside of the water tower, and the temperature dial has a scale value inside.

[0021] By adopting the above technical solution, the scale value set inside the temperature dial provides a reference for the temperature of the water in the water tower.

[0022] A further feature of this invention is that a sealing ring is fixedly connected inside the water tower, and the number of the sealing rings is two.

[0023] By adopting the above technical solution, the sealing ring prevents water inside the water tower from overflowing from the gaps in the pipes and exhaust pipes.

[0024] A further feature of this invention is that a filter pad is inserted inside the cylindrical air hood, and the filter pad consists of two layers.

[0025] By adopting the above technical solution, the flue gas discharged from the exhaust pipe into the cylindrical gas hood is filtered through the action of the filter pad.

[0026] The beneficial effects of this utility model are: This invention, through the coordinated arrangement of a drying chamber, water tank, water tower, cabinet door, gas collection hood, water pump, coil, pipe, exhaust pipe, cylindrical gas hood, water outlet pipe, valve hole, valve, stud, pulley, and water supply pipe, enables the device to operate by filling the water tower with an appropriate amount of water, submerging the coil, and then shutting off the water pump. During the drying process, the high-temperature flue gas from the drying chamber is collected by the gas collection hood and transported through the pipe to the inside of the coil. As the high-temperature flue gas travels through the coil, its high temperature is transferred to the coil wall, allowing heat exchange between the coil wall and the water in the water tower. After this heat exchange, the water cools and is discharged through the exhaust pipe. When hot water is needed, the valve is opened, and the heated water from the water tower flows into a bucket. In this way, the residual heat from the high-temperature flue gas discharged during the drying process is reused.

[0027] This invention, through the coordinated arrangement of a cylinder, top plate, groove, liner, slot, bottom plate, pad, return air plate, hot air blower, temperature dial, sealing ring, and filter, enables the device to automatically open the drying chamber door by moving the top plate upward under the action of the cylinder. When the door is under force, the sliding connection between the pulley and the groove ensures smooth movement. The door passes through the slot during force-bearing movement, providing guidance for its vertical movement. The pad... The bottom plate keeps the bottom of the drying room from the ground, preventing moisture from the ground from entering the drying room. Two return air plates allow for effective airflow convection inside the drying room, improving the efficiency of material drying. The hot air blower blows air into the drying room, making the temperature inside the drying room more even. The scale value set inside the temperature gauge provides a reference for the temperature of the water in the water tower. The sealing ring prevents water inside the water tower from overflowing from the gaps in the pipes and exhaust pipes. The filter cloth filters the flue gas discharged from the exhaust pipe into the columnar air hood. Attached Figure Description
