Description

Technical Field

[0001] The invention relates to the technical field of air heaters, in particular to a continuous air heating device capable of uniform thermal contact. Background Art

[0002] An air heater is a device used to heat air, usually using electricity or other energy sources to provide heat. It is widely used in industrial and civilian fields. The working principle of an air heater is very simple. It usually includes a chassis and a heating element (such as a heating wire). When air enters the chassis, the air is heated by the heating element and then discharged after reaching a certain temperature.

[0003] However, existing air heaters sometimes experience uneven heating during actual operation, especially when the gas flows faster in the chassis. The closer the area is to the heating element, the better the heating effect, and the farther the area is from the heating element, the worse the heating effect. When used in industry, this uneven heating of the gas can easily affect the final quality of the product. In addition, current air heaters are sometimes equipped with cleaning mechanisms and dust removal mechanisms, but the existing cleaning mechanisms can often only clean the inner wall of the air heater and cannot clean a specific heating element alone. In order not to affect the smoothness of the air, the dust removal mechanism can often only intercept large particles of impurities. Therefore, after long-term use, more impurities will accumulate on the surface of the heating element inside the air heater, making it difficult for the heat of the heating element to be effectively dissipated. Summary of the Invention

When the present invention is in use, the staff needs to connect the air inlet pipe to the external air outlet device and connect the air outlet pipe to the external air inlet device. At this time, the gas in the external air outlet device will The air flows into the external air intake device along the air intake pipe-air intake channel-first heating chamber-second heating chamber-air outlet pipe.

The first heating tube is provided in several groups, and several groups of the first heating tubes are distributed in an annular manner in the first heating chamber. The second heating tube is provided in several groups, and several groups of the second heating tubes are distributed in an annular manner in the second heating chamber. The gas in the external air outlet device flows through the first heating chamber and the second heating chamber, and is continuously heated by the first heating tube and the second heating tube. Compared with the current air heating device, the present invention is provided with a first motor and a turntable. In the process of heating the gas in the first heating chamber and the second heating chamber, the first motor and the turntable can drive several groups of first heating tubes and several groups of second heating tubes to rotate in the first heating chamber and the second heating chamber. Through the above technical solution, the present invention can, on the one hand, ensure uniform contact between the gas and the heating component. On the other hand, during operation, even if the heating component in a certain area fails and cannot heat normally, the present invention can still ensure uniform heating of the gas by controlling the rotation of several groups of first heating tubes and second heating tubes.

[0006] Furthermore, two groups of air pumps are provided on the side of the second end cover away from the heating cylinder, and a cleaning component and a traction component are provided inside the heating cylinder. The cleaning component is provided with two groups, one of which is provided at one end of the first heating chamber close to the second end cover, and the other is provided at one end of the second heating chamber close to the second end cover. Each group of the cleaning components is connected to a group of air pumps through a hose. The traction component is provided with two groups, one of which is provided at one end of the first heating chamber close to the first end cover, and the other is provided at one end of the second heating chamber close to the first end cover. Each group of the traction components is connected to a group of cleaning components. After the work of the present invention is completed, Afterwards, the heating components in the heating tube can be cleaned through the cleaning assembly, the traction assembly and the air pump. For example: when the present invention needs to clean several groups of first heating tubes, it is only necessary to use the first motor and the turntable to drive several groups of first heating tubes to be aligned with the cleaning assembly in the first heating chamber in sequence. When a group of first heating tubes is aligned with the cleaning assembly located in the first heating chamber, the traction assembly in the first heating chamber is turned on, and the cleaning assembly is driven to move in the first heating chamber by the traction assembly. When moving, the cleaning assembly will clean the first heating tubes aligned with it, and the dust and other impurities generated by the cleaning will be discharged to the outside through the air pump (the steps for cleaning the first heating tube and the second heating tube of the present invention are the same and will not be repeated here).

[0007] Furthermore, the cleaning component includes a movable seat, and the movable seat is provided with a first movable groove at one end away from the second end cover, and a second movable groove is provided at one end of the movable seat close to the second end cover, the diameter of the second movable groove is larger than the diameter of the first movable groove, and the second movable groove is connected to the air pump through a hose, and a fixing ring is provided between the first movable groove and the second movable groove, and a cleaning sleeve is provided inside the fixing ring, and the diameter of the cleaning sleeve is the same as that of the first heating tube and the second heating tube, and the fixing ring is connected to the movable seat through a sealing spring rod. When the cleaning component of the present invention is moved, the staff can turn on the air pump to generate a set of suction through the air pump, and then suck away the gas in the second movable groove. Under the action of air pressure, the The fixed ring will move in the direction away from the first movable groove, and finally the first movable groove is connected to the second movable groove. When the cleaning sleeve follows the movable seat to move along the heating component (the first heating tube, the second heating tube), the outer wall of the heating component can be cleaned through the cleaning sleeve, and the impurities generated by the cleaning can be discharged to the outside through the air pump. Finally, the spring on the sealing spring rod in the present invention is fixedly connected to the fixed ring. The staff can change the position of the cleaning sleeve by adjusting the suction strength generated by the air pump (the greater the suction generated by the air pump, the further away the cleaning sleeve is from the first movable groove). By intermittently adjusting the suction generated by the air pump, the cleaning sleeve in the present invention can make reciprocating motion in the movable seat, thereby performing cyclic friction on the outer wall of the heating component, thereby improving the cleaning effect.

[0008] Furthermore, each group of the traction components includes two third motors and two winding drums, each of the third motors is connected to a winding drum, and each of the winding drums is connected to a positioning block through a traction rope, and the cleaning component is driven to move in the direction away from the second end cover by the third motor and the winding drum. Finally, the hose used to connect the cleaning component and the air pump in the present invention is wound on the winding mechanism (not shown in the figure), and the cleaning component is driven to move in the direction close to the second end cover by the winding mechanism and the hose. The inner walls of the first heating chamber and the second heating chamber are provided with slide grooves, and the outer side of the movable seat is provided with a positioning block, and the positioning block cooperates with the slide groove. The positioning block and the slide groove can prevent the cleaning component from offsetting during movement.

[0009] Furthermore, a temperature measuring component is provided on the side of the first movable groove away from the second movable groove. When the present invention is working, several groups of first heating tubes or second heating tubes will circulate through the temperature measuring component. The present invention can detect whether a certain group of first heating tubes or second heating tubes is damaged through the temperature measuring component, thereby facilitating the staff to quickly and accurately determine the location to be repaired during subsequent maintenance.

[0010] Furthermore, a sealing ring and a cylinder are provided on the outside of the heating cylinder, and a third through hole and a fourth through hole are provided at one end of the second heating chamber away from the first heating chamber, a temperature regulating seat is provided below the outer cylinder, and a temperature regulating mechanism is provided inside the temperature regulating seat, and the temperature regulating mechanism is connected with the outer cylinder through a connecting pipe, and an exhaust pipe is provided on the air inlet pipe, and the exhaust pipe runs through the outer cylinder, and valves are provided on the air outlet pipe, the air inlet pipe and the exhaust pipe. When the present invention is working normally, the valve on the exhaust pipe is closed, and the valves on the air outlet pipe and the air inlet pipe are opened. At the same time, the third through hole is connected with the air outlet pipe, and the fourth through hole is aligned with the sealing ring. At this time, when the external air outlet equipment transports gas to the present invention, the gas will flow along the air inlet pipe-air inlet channel-first heating chamber-second heating chamber-outlet pipe. If the internal temperature of the heating cylinder needs to be urgently and significantly reduced during operation of the present invention, it is only necessary to adjust the temperature generated by the first heating tube and the second heating tube first, and then close the outlet pipe. The valves on the air pipe and the air inlet pipe, open the valve on the air outlet pipe, and finally open the temperature control mechanism and the cylinder. The cylinder can drive the sealing ring away from the fourth through hole, and the temperature control mechanism can transport low-temperature gas to the outer tube. At this time, the gas output by the temperature control mechanism will flow along the connecting pipe-outer tube-second heating chamber-first heating chamber-air inlet channel-inlet pipe-exhaust pipe. During the flow, the gas can quickly reduce the internal temperature of the heating tube to the target value. When the temperature in the heating tube reaches the target value, the staff needs to close the valve and the temperature control mechanism on the air outlet pipe, and then use the cylinder to block the fourth through hole again with the sealing ring, and finally open the valves on the air outlet pipe and the air inlet pipe. At this time, the present invention will continuously heat the air at the adjusted temperature. Compared with the current temperature control method of the air heater, the present invention does not need to be disassembled from the production line (that is, the present invention does not need to be separated from the external air intake equipment and the external air outlet equipment), while ensuring the speed of temperature control.

[0011] Furthermore, the temperature control mechanism includes a fan and a refrigeration pipe. A purification chamber is also provided in the temperature control seat. A mounting plate is provided in the purification chamber. Several groups of refrigeration pipes are provided, and several groups of refrigeration pipes are evenly installed on the mounting plate. One end of the purification chamber is connected to the fan, and the other end of the purification chamber is connected to the outer cylinder through a connecting pipe. When the temperature control mechanism in the present invention is working, the fan will transport the outside air into the purification chamber for cooling, and then transport it to the outer cylinder through the connecting pipe, so as to quickly reduce the internal temperature of the heating cylinder to the target value.

[0012] Furthermore, a second motor is provided on the outside of the temperature regulating seat, and the second motor is connected to the mounting plate. A discharge channel is provided under the purification chamber, and several groups of baffles are provided on the mounting plate. A group of filter plates is provided between each two groups of baffles. A fixed plate is fixedly installed at one end of the purification chamber close to the discharge channel. The present invention drives the mounting plate to rotate by the second motor. When the mounting plate rotates, each group of baffles passes through the position between the fixed plate and the discharge channel. When the fan in the present invention delivers air to the purification chamber, there are required to be two groups of baffles under the fixed plate. The fixed plate and the baffle under the fixed plate ensure that the purification chamber is separated from the discharge channel to prevent air from entering the discharge channel. At this time, the air will pass through the filter plate into the outer cylinder, and the filter plate prevents impurities in the air from polluting the internal environment of the outer cylinder and the heating cylinder. Compared with the current The diameter is purified by a filter. The present invention can change the positions of several groups of filter plates at any time through the second motor and the mounting disk, and detect the ventilation performance of several groups of filter plates when the fan is working. The filter plates in the present invention are connected with the baffles by a snap-fit ​​connection. When the present invention transports air to the outer cylinder, if it is detected that the amount of air transported is insufficient, the staff can drive the mounting disk to rotate through the second motor to make a group of filter plates above the fixed plate exchange positions with the filter plates below the fixed plate. At this time, the staff will remove the filter plates below the fixed plate after the exchange of positions for inspection to determine whether the air transported to the outer cylinder by the fan is insufficient because the filter plates above the fixed plate are blocked. If it is because the filter plates above the fixed plate are blocked, the staff can replace the filter plates above the fixed plate without turning off the fan, thereby ensuring the temperature adjustment speed of the heating cylinder.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: compared with the current air heating equipment, the present invention is provided with a first motor and a turntable. In the process of heating the gas in the first heating chamber and the second heating chamber, the first motor and the turntable can drive several groups of first heating tubes and several groups of second heating tubes to rotate in the first heating chamber and the second heating chamber. On the one hand, the gas can be in uniform contact with the heating component. On the other hand, during operation, even if the heating component in a certain area fails and cannot generate heat normally, the uniform heating of the gas can still be ensured by controlling the rotation of several groups of first heating tubes and second heating tubes. The present invention is also provided with a cleaning component and a traction component. The traction component can control the cleaning component to move along the heating component. The cleaning sleeve in the cleaning component can clean the heating component in the heating tube to avoid accumulation on the outer wall of the heating component. A large amount of impurities make it difficult for heat to dissipate. At the same time, the cleaning component can also detect whether a group of the first heating tube or the second heating tube is damaged, so as to facilitate the staff to quickly and accurately determine the location to be repaired during subsequent maintenance. The cleaning component in the present invention is connected to the air pump. The staff can change the position of the cleaning sleeve by adjusting the suction strength generated by the air pump. By intermittently adjusting the suction generated by the air pump, the cleaning sleeve in the present invention can make reciprocating motion in the movable seat, thereby cyclically rubbing the outer wall of the heating component, thereby improving the cleaning effect. Finally, the present invention is also provided with a sealing ring and a temperature control mechanism, which controls the connection state between the outer cylinder and the second heating chamber through the sealing ring. The internal temperature of the heating cylinder can be quickly changed through the temperature control mechanism. Compared with the current temperature control method of the air heater, the present invention does not need to be disassembled from the production line, while ensuring the speed of temperature control.

During the flow, the gas can quickly reduce the internal temperature of the heating tube 7 to the target value. When the temperature inside the heating tube 7 reaches the target value, the staff needs to close the valve and temperature control mechanism on the outlet pipe 2, and then use the cylinder to block the fourth through hole with the sealing ring 74 again. Finally, open the valves on the outlet pipe 2 and the inlet pipe 5. At this time, the present invention will continuously heat the air at the adjusted temperature. Compared with the current temperature control method of the air heater, the present invention does not need to be disassembled from the production line (that is, the present invention does not need to be separated from the external air intake equipment and the external air outlet equipment), while ensuring the speed of temperature control.

A discharge channel is provided below the purification chamber 42, and a plurality of baffles 451 are provided on the mounting plate 45. A group of filter plates 452 are provided between each two groups of baffles 451. A fixed plate 46 is fixedly installed at one end of the purification chamber 42 near the discharge channel. The present invention drives the mounting plate 45 to rotate by the second motor 44. When the mounting plate 45 rotates, each group of baffles 451 passes through the fixed plate 46 and the mounting plate 45. At the position between the discharge channel, when the fan 41 in the present invention delivers air to the purification chamber 42, two sets of baffles 451 are required under the fixed plate 46. The fixed plate 46 and the baffle 451 under the fixed plate 46 ensure that the purification chamber 42 is separated from the discharge channel to prevent air from entering the discharge channel. At this time, the air will pass through the filter plate 452 into the outer cylinder 1, and the impurities in the air will not pollute the internal environment of the outer cylinder 1 and the heating cylinder 7 through the filter plate 452. Compared with the current diameter filter net The present invention can change the position of several groups of filter plates 452 at any time through the second motor 44 and the mounting plate 45, and detect the ventilation performance of several groups of filter plates 452 when the fan 41 is working. The filter plates 452 in the present invention are connected to the baffle 451 by a snap-fit ​​connection. When the present invention is delivering air to the outer tube 1, if it is detected that the delivered air volume is insufficient, the staff can drive the mounting plate 45 to rotate by the second motor 44, so that a group of filter plates 452 above the fixed plate 46 and the filter plates 452 below the fixed plate 46 are exchanged. At this time, the staff removes the filter plates 452 below the fixed plate 46 after the exchange for inspection to determine whether the filter plates 452 above the fixed plate 46 are blocked, resulting in insufficient air delivered to the outer tube 1 by the fan 41. If the filter plates 452 above the fixed plate 46 are blocked, the staff can replace the filter plates 452 above the fixed plate 46 without turning off the fan 41, thereby ensuring the temperature control speed of the heating tube 7.

[0035] The working principle of the present invention is as follows: before work, the staff needs to connect the air inlet pipe 5 to the external air outlet device, and connect the air outlet pipe 2 to the external air inlet device. At this time, the gas in the external air outlet device will flow into the external air inlet device along the air inlet pipe 5-air inlet channel 71-first heating chamber 72-second heating chamber 73-air outlet pipe 2. When the gas in the external air outlet device flows through the first heating chamber 72 and the second heating chamber 73, the gas is continuously heated by the first heating tube 81 and the second heating tube 82. After the work of the present invention is completed, if it is necessary to clean several groups of first heating tubes 81, the first motor 3 can be turned on, and the first motor 3 and the turntable 8 can be used to drive several groups of first heating tubes 81 to be aligned with the cleaning components in the first heating chamber 72 in turn. When a group of first heating tubes 81 is aligned with the cleaning components in the first heating chamber 72 When the components are aligned, the traction component in the first heating chamber 72 is turned on, and the cleaning component in the first heating chamber 72 is driven to move in the first heating chamber 72 by the traction component in the first heating chamber 72. When moving, the cleaning component in the first heating chamber 72 will clean the first heating tube 81 aligned with it, and the dust and other impurities generated by the cleaning will be discharged to the outside through the air pump 121. Similarly, if it is necessary to clean several groups of second heating tubes 82, the first motor 3 and the turntable 8 can be used to drive several groups of second heating tubes 82 to be aligned with the cleaning components in the second heating chamber 73 in turn, and then the traction component in the second heating chamber 73 is used to drive the cleaning components in the second heating chamber 73 to move in the second heating chamber 73. When moving, the cleaning component in the second heating chamber 73 will clean the second heating tube 82 aligned with it.
