Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology for hot air units, and in particular relates to a heat dissipation structure for explosion-proof hot air units. Background Technology

[0002] Outdoor explosion-proof hot air blower units are hot air blower equipment with explosion-proof function used in outdoor environments. Hot air blower units generally heat the air by burning fuel (such as natural gas, diesel, etc.) or using electricity, and then blow the hot air out through a fan. For combustion hot air blowers, the fuel burns in the combustion chamber, and the heat generated is transferred to the air through a heat exchanger, which raises the air temperature.

[0003] Most existing explosion-proof hot air handling unit heat dissipation structures directly use fans to blow air onto the hot air handling unit for heat dissipation, without a dust filtration structure. This may cause the unit to become less efficient or even damaged due to dust entering the hot air handling unit or fan. Therefore, we propose an explosion-proof hot air handling unit heat dissipation structure. Utility Model Content

[0004] The purpose of this utility model is to provide a heat dissipation structure for an explosion-proof hot air unit. The structure uses a motor to drive a rotating shaft and a fan to rotate, and then the airflow is discharged through a dustproof cylinder. The dustproof plate inside the dustproof cylinder filters the dust inside and outside the device, thus solving the problem that existing explosion-proof hot air units are inconvenient for filtering dust.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a heat dissipation structure for an explosion-proof hot air unit, comprising a ventilation and heat dissipation mechanism and a housing. A dustproof mechanism is installed inside the housing. An air supply duct is fixedly connected to the inner wall of the housing. A fixed cylinder is fixedly connected to the left side of the air supply duct. A motor is fixedly connected to the inner wall of the fixed cylinder. The output shaft at the bottom of the motor is fixedly connected to a rotating shaft via a coupling. A fan is fixedly connected to the right side of the rotating shaft. The dustproof cylinder is fixedly connected to the inner wall of the housing. The motor drives the rotating shaft to rotate, which in turn causes the fan to rotate, thus drawing airflow through the air supply duct into the device. The airflow then exits from the dustproof cylinder. A dustproof plate inside the dustproof cylinder filters dust from both inside and outside the device, achieving the effect of both heat dissipation and dust filtration, preventing dust from adhering to the device or fan and causing inefficiency or damage to the entire device.

[0007] Furthermore, the dustproof cylinder has a semi-circular groove inside, and there are two semi-circular grooves in total. A semi-circular frame is inserted into the inner wall of the semi-circular groove, and a dustproof plate is fixedly connected to the outer surface of the semi-circular frame. Through the dustproof plate, the dust inside and outside of the device can be filtered.

[0008] Furthermore, the dustproof cylinder has two slots inside. A semi-circular insert plate is slidably connected to the inner wall of the slot. The inner wall of the semi-circular insert plate is slidably connected to the outer surface of the dustproof plate. The semi-circular insert plate can fix the dustproof plate.

[0009] Furthermore, the air duct has a groove 1 inside, and there are two grooves in total. A plug 1 is inserted into the inner wall of the groove 1. The side of the plug 1 that is close to each other is fixedly connected to the outer surface of the dustproof plate. Through the dustproof plate, the effect of preventing dust from outside the device from adhering to the fan is achieved.

[0010] Furthermore, the dustproof mechanism includes four support columns that contact the inner wall of the housing. A connecting block is fixedly connected to the outer surface of each support column, thereby enabling the installation of the cooling plate.

[0011] Furthermore, a plurality of connecting blocks are provided, and a plug rod is inserted into the inner wall of the connecting block. The outer surface of the plug rod is inserted into the inner wall of the housing, thereby achieving the effect of fixing the cooling plate through the plug rod.

[0012] Furthermore, a cooling plate is fixedly connected to the top of the support column, and a connecting strip is fixedly connected to the inner wall of the cooling plate. The connecting strip is provided with several connecting cylinders fixedly connected to the right side of the air supply duct. Through the connecting strip, the effect of auxiliary heat dissipation for the hot air unit is achieved.

[0013] Furthermore, the connecting cylinder has two grooves inside. A second insert block is inserted into the inner wall of the groove. A dustproof plate is fixedly connected to the side of the two insert blocks that are close to each other. The insert rod is inserted into the housing through the connecting block on the support column to fix the position of the cooling plate. Then, the dust in the device will be filtered by the dustproof plate in the connecting cylinder, which can prevent dust from adhering to the fan inside the device. At the same time, the air inside the device will pass through the cooling plate and then be discharged, which can blow out the cold air to achieve the heat dissipation effect.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model incorporates a fan and a motor. The motor is fixed in place by a fixed cylinder connected to the air supply duct, preventing it from rotating on its own. The motor then drives the fan to rotate via a rotating shaft. Airflow is discharged through a dustproof cylinder connected to the housing. The dustproof plate inside the dustproof cylinder filters dust. The motor drives the rotating shaft to rotate, which in turn rotates the fan, thus drawing airflow into the device through the air supply duct. The airflow then exits from the dustproof cylinder. The dustproof plate inside the dustproof cylinder filters dust from both inside and outside the device. This achieves the effect of simultaneously cooling the device and filtering dust, preventing dust from adhering to the device or fan, which could lead to low efficiency or damage to the entire device.

[0016] 2. This utility model incorporates a cooling plate. The second insert block is installed in the groove on the connecting cylinder, thus installing the second dustproof plate and preventing dust from entering the air duct. The support column is placed on the housing, and the insert rod is aligned with the connecting block and the housing. The insert rod is then inserted to fix the position of the support column and the cooling plate. Through the connecting block on the support column and the insert rod, the insert rod is inserted into the housing to fix the position of the cooling plate. Dust inside the device is then filtered by the second dustproof plate inside the connecting cylinder, preventing dust from adhering to the fan inside the device. Simultaneously, the air inside the device passes through the cooling plate before being discharged, effectively blowing out cool air for heat dissipation.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6As shown, this utility model is a heat dissipation structure for an explosion-proof hot air unit, including a ventilation and heat dissipation mechanism 1 and a housing 101. A dustproof mechanism 2 is installed inside the housing. An air supply duct 102 is fixedly connected to the inner wall of the housing 101. A fixed cylinder 103 is fixedly connected to the left side of the air supply duct 102. A motor 104 is fixedly connected to the inner wall of the fixed cylinder 103. A centrifugal fan draws cold air into the hot air furnace, where it exchanges heat with the electric heating element, heating the cold air into hot air. A rotating shaft 105 is fixedly connected to the bottom output shaft of the motor 104 via a coupling. A fan 106 is fixedly connected to the right side of the rotating shaft 105. A dustproof cylinder 108 is fixedly connected to the inner wall of the housing 101. The motor 104 drives... The rotating shaft 105 rotates, and the heated air is delivered to the wellhead through a preset air duct to ensure that the temperature inside the wellhead is at the set temperature value. Then, the rotating shaft 105 causes the fan 106 to rotate, thereby injecting airflow into the device through the air supply duct 102. The airflow will then be discharged from the dustproof duct 108. The dustproof plate 111 inside the dustproof duct 108 will filter the dust inside and outside the device. This heating unit is designed to ensure that the temperature of the mine shaft is kept above 2°C in winter. It achieves the effect of cooling the device while filtering dust, preventing dust from adhering to the device or fan, which would lead to low efficiency or damage to the entire device.

[0029] Among them, such as Figure 5 As shown, the dustproof cylinder 108 has a semi-circular groove 109 inside, and there are two semi-circular grooves 109. A semi-circular frame 110 is inserted into the inner wall of the semi-circular groove 109, and a dustproof plate 111 is fixedly connected to the outer surface of the semi-circular frame 110. Its outer shell is generally made of special explosion-proof materials, such as high-strength metal alloys, which can withstand the explosion pressure that may occur inside without breaking.

[0030] Among them, such as Figure 4-5 As shown, the dustproof cylinder 108 has a slot 112 inside, and there are two slots 112. A semi-circular insert plate 113 is slidably connected to the inner wall of the slot 112. The inner wall of the semi-circular insert plate 113 is slidably connected to the outer surface of the dustproof plate 111. The electrical components (such as motors, controllers, etc.) in the unit are all explosion-proof products. These explosion-proof electrical components are specially designed and packaged so that the energy sources such as electric sparks generated during normal operation or fault conditions will not cause the surrounding explosive gas mixture to explode.

[0031] Among them, such as Figure 3As shown, the air supply duct 102 has a groove 114 inside, and there are two grooves 114. Inserts 115 are inserted into the inner wall of the groove 114. The side of the inserts 115 that are close to each other is fixedly connected to the outer surface of the dustproof plate 107. The system includes a temperature sensor, an overcurrent protection device, etc. The temperature sensor can monitor the heating temperature to prevent the temperature from being too high and causing danger. The overcurrent protection device can cut off the circuit when the current is abnormal to avoid safety hazards caused by electrical faults.

[0032] Among them, such as Figure 6 As shown, the dustproof mechanism 2 includes a support column 201 that contacts the inner wall of the housing 101. There are four support columns 201 in total. A connecting block 202 is fixedly connected to the outer surface of the support column 201. It is mainly used in outdoor industrial places where there are flammable and explosive gases or dust, such as outdoor work areas in industries such as petrochemical, natural gas extraction, oil refinery, and coal mine.

[0033] Among them, such as Figure 6 As shown, there are several connecting blocks 202. A plug rod 203 is inserted into the inner wall of the connecting block 202. The outer surface of the plug rod 203 is inserted into the inner wall of the housing 101. It can provide a warm and comfortable working environment for the staff, while ensuring safety and avoiding explosion accidents caused by factors such as electric sparks generated by the equipment.

[0034] Among them, such as Figure 1-6 As shown, a cooling plate 204 is fixedly connected to the top of the support column 201, and a connecting strip 205 is fixedly connected to the inner wall of the cooling plate 204. Several air supply ducts 102 are provided on the connecting strip 205, and a connecting cylinder 206 is fixedly connected to the right side. When the fan operates, it delivers the heated air out. The type of fan can be a centrifugal fan or an axial fan, etc., which is selected according to the actual air volume and air pressure requirements. It can deliver hot air to the area that needs to be heated at a certain wind speed and flow rate.

[0035] As shown in Figure 2, the connecting cylinder 206 has two grooves 207 inside. Insert blocks 208 are inserted into the inner wall of the grooves 207. Dustproof plates 209 are fixedly connected to the side of the insert blocks 208 that are close to each other. Through the connecting block 202 and the insert rod 203 on the support column 201, the insert rod 203 is inserted into the housing 101 through the connecting block 202 to fix the position of the cooling plate 204. Then, the dust in the device will be filtered by the dustproof plates 209 inside the connecting cylinder 206, which can prevent dust from adhering to the fan inside the device. At the same time, the air inside the device will pass through the cooling plate 204 and then be discharged, which can blow out cold air to achieve the heat dissipation effect.

[0036] One specific application of this embodiment is:

[0037] When staff need to use the equipment, they first ventilate and cool the device using the ventilation and heat dissipation mechanism 1. The motor 104 can be turned on, and its position is then fixed by the fixing cylinder 103 connected to the air supply duct 102, preventing the motor 104 from rotating on its own. The motor 104 then drives the fan 106 to rotate via the rotating shaft 105. The airflow is then discharged through the dustproof cylinder 108 connected to the housing 101. The dustproof plate 111 inside the dustproof cylinder 108 filters the dust. To replace the dustproof plate 111, first remove the semi-circular insert 113 from the slot 112, and then remove the dustproof plate 111 along with the semi-circular frame 110 from the semi-circular groove 109. After removing the dustproof plate 111, the insert block 115 can be installed in the groove 114, thus completing the installation of the dustproof plate 107. This prevents dust from adhering to the fan 106. The motor 104 drives the rotating shaft 105 to rotate, which in turn causes the fan 106 to rotate, thereby drawing airflow into the device through the air supply duct 102. The airflow then exits from the dustproof duct 108. The dustproof plate 111 inside the dustproof duct 108 filters dust from inside and outside the device, achieving the effect of both heat dissipation and dust filtration, preventing dust from adhering to the device or fan and causing low efficiency or damage to the entire device.

[0038] Then, the dustproof mechanism 2 can be used to assist in heat dissipation of the device. First, the second insert block 208 is installed in the groove 207 on the connecting cylinder 206, which completes the installation of the second dustproof plate 209. This also prevents dust from entering the air supply duct 102. Then, the support column 201 is placed on the housing 101. The insert rod 203 is aligned with the connecting block 202 and the housing 101. The insert rod 203 is inserted to fix the position of the support column 201 and the cooling plate 204. Through the connecting block 202 and the insert rod 203 on the support column 201, the insert rod 203 is inserted into the housing 101 through the connecting block 202 to fix the position of the cooling plate 204. Then, the dust in the device will be filtered by the second dustproof plate 209 in the connecting cylinder 206, which achieves the effect of preventing dust from adhering to the fan inside the device. At the same time, the device can be placed on the connecting strip 205 to work, which also plays a role in assisting heat dissipation.
