Description

Technical Field

[0001] The utility model relates to the technical field of centralized heating circulation fans, in particular to a centralized heating circulation fan. Background Art

[0002] Centralized heating circulation fans heat the air and transport it to the corresponding positions. Most of the existing tunnel-type baking ovens are self-heating modes, that is, each small section of the oven is a heating unit. This method makes the oven structure complex and energy-intensive in terms of processing, assembly and installation, and its utilization rate is greatly reduced. Therefore, centralized heating circulation fans solve the existing problems of tunnel-type baking ovens. Centralized heating circulation fans can be installed in an integrated or split manner, thereby simplifying the structure of the oven and greatly reducing its cost.

[0003] The Chinese patent "A thermal circulation intelligent oven" authorization announcement number "CN213315995U" realizes the circulation heating of the oven body through a heating device, a recovery pipe, a hot air pipe and a dehumidification pipe, realizes the control of multiple heating sections inside the oven body, and improves the heating effect of the shoe workpiece.

[0004] The above-mentioned dehumidification pipe is located at the rear end of the oven body, and the recovery pipe is located on one side of the oven body, which can easily cause a large amount of moisture in the oven body to be extracted by the recovery pipe and then flow back into the oven body through the heating device and the hot air pipe, thereby affecting the processing effect of the heating device on the shoe workpiece.

[0005] Therefore, a centralized heating circulation fan is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a centralized heating circulation fan in order to solve the above problems, thereby improving the problem that the recovery pipe easily extracts most of the moisture in the oven body and then flows back into the oven body through the heating device.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a centralized heating circulation fan, comprising: an oven, a circulating hot air blower is fixedly connected to the top of the oven, and one side of the circulating hot air blower is connected to an air outlet duct and a return air duct; a dehumidification mechanism, and the surface of the return air duct is provided with a dehumidification mechanism; wherein the dehumidification mechanism comprises a dehumidification frame connected to one end of the return air duct, both sides of the dehumidification frame are connected to a processing frame, both sides of the inner wall of the dehumidification frame are fixedly connected with a sealing ring, the inner wall of the sealing ring is slidably connected with a drying plate, the number of the drying plates is three, the interior of the drying plates is filled with desiccant, one side of one of the drying plates is fixedly connected with a movable frame, the surface of the movable frame is slidably connected to the inner wall of one of the processing frames, and the surface of the processing frame is provided with a dehumidification component. The drying plate is used to remove moisture from the hot air in the return air duct, thereby preventing moisture from flowing back into the oven, ensuring the heating effect of the centralized heating circulation fan on the workpiece. The movable frame is used to replace the drying plate in the dehumidification frame, ensuring the effect of removing moisture from the hot air in the return air duct.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-4 As shown, a centralized heating circulation fan comprises: an oven 1, a circulating hot air blower 2 is fixedly connected to the top of the oven 1, and one side of the circulating hot air blower 2 is connected to an air outlet duct 3 and a return air duct 4; a dehumidification mechanism 5, and the surface of the return air duct 4 is provided with a dehumidification mechanism 5; wherein the dehumidification mechanism 5 comprises a dehumidification frame 51 connected to one end of the return air duct 4, both sides of the dehumidification frame 51 are connected to a processing frame 52, both sides of the inner wall of the dehumidification frame 51 are fixedly connected to a sealing ring 54, the inner wall of the sealing ring 54 is slidably connected to a drying plate 53, the number of the drying plates 53 is three, the interior of the drying plates 53 is filled with desiccant, one side of one of the drying plates 53 is fixedly connected to a movable frame 55, the surface of the movable frame 55 is slidably connected to the inner wall of one of the processing frames 52, the surface of the processing frame 52 is provided with a dehumidification component 56, the surface of the movable frame 55 is fixedly connected to an elastic soft block 566, and one side of the processing frame 52 is fixedly connected to a round rod 567.

[0026] A worm wheel fan is arranged on the inner wall of the circulating hot air blower 2 away from the air outlet duct 3, a matrix heating rod is fixedly connected to the inner wall of the circulating hot air blower 2, the bottom end of the air outlet duct 3 is connected to the air injection duct, and the rear end of the dehumidification frame 51 is connected to the return duct.

[0027] When it is necessary to heat the shoe workpiece, the circulating hot air blower 2 and the oven 1 are manually turned on, and the oven 1 transports the shoe workpiece. The circulating hot air blower 2 generates hot air that is evenly sprayed into the oven 1 through the air outlet pipe 3 and the air spray pipe to heat the moving shoe workpiece. The air in the oven 1 is sucked into the return pipe, and the air in the return pipe passes through the drying plate 53. The desiccant in the drying plate 53 absorbs moisture in the air. The dried air is drawn into the circulating hot air blower 2 through the return air pipe 4 for heating, and is sprayed into the oven 1 again through the air outlet pipe 3. When it is no longer necessary to heat the shoe workpiece, the circulating hot air blower 2 and the oven 1 are manually turned off.

[0028] When the drying plate 53 in the dehumidification frame 51 has been used for a period of time, the movable frame 55 is pushed, and the movable frame 55 and the elastic soft block 566 move simultaneously. The elastic soft block 566 moves to abut against the round rod 567, so that the second drying plate 53 moves just into the dehumidification frame 51, and the pushing of the movable frame 55 stops.

[0029] like Figure 3-4As shown, the dehumidification component 56 includes a shunt pipe 561 connected to the front end of the processing frame 52, the other end of the shunt pipe 561 is connected to the inner wall of the air outlet pipe 3, the rear end of the processing frame 52 is connected to the one-way air outlet pipe 565, the inner wall of the shunt pipe 561 is rotatably connected to the driven wheel 562, the inner wall of the shunt pipe 561 is fixedly connected to a sealing ring 564, the inner wall of the sealing ring 564 is slidably connected to a sealing frame 563, the rear end of the oven 1 is fixedly connected to a limiting block 569, the inner wall of the sealing frame 563 is slidably connected to a positioning rod 568, and the surface of the positioning rod 568 is clamped on the inner wall of the oven 1.

[0030] The sealing ring 54 and the blocking ring 564 are both made of silicone rubber components. The one-way air outlet pipe 565 includes an exhaust pipe and a one-way valve. The one-way valve is used to prevent external air from flowing into the processing frame 52 through the exhaust pipe.

[0031] When there are two used drying plates 53 in one of the processing frames 52, the corresponding positioning rod 568 is pulled to push the blocking frame 563 to abut against the limit block 569, so that the shunt pipe 561 is opened. At this time, part of the hot air in the air outlet pipe 3 flows into the shunt pipe 561. The hot air in the shunt pipe 561 passes through the driven wheel 562, so that the hot air is evenly blown to the used drying plates 53 to dry the moisture inside. The hot air in the processing frame 52 is discharged through the one-way air outlet pipe 565. After drying for a period of time, the blocking frame 563 is pushed to block the shunt pipe 561.

[0032] When the utility model is in use, the circulating hot air blower 2 and the oven 1 are manually turned on, the oven 1 conveys the shoe workpiece, the circulating hot air blower 2 generates hot air which is sprayed evenly into the oven 1 through the air outlet pipe 3 and the air spray pipe to heat the moving shoe workpiece, the air in the oven 1 is sucked into the return pipe, the air in the return pipe passes through the drying plate 53, the desiccant in the drying plate 53 adsorbs the moisture in the air, the dried air is drawn into the circulating hot air blower 2 through the return pipe 4 for heating, and is sprayed into the oven 1 again through the air outlet pipe 3, when the shoe workpiece does not need to be heated, the circulating hot air blower 2 and the oven 1 are manually turned off. After the drying plate 53 in the dehumidification frame 51 is used for a period of time, the movable frame 55 is pushed, the movable frame 55 and the elastic soft block 566 move at the same time, the elastic soft block 566 moves against the round rod 567, so that the second drying plate 53 is just moved into the dehumidification frame 51, and the pushing of the movable frame 55 is stopped.

[0033] It should be noted that the oven 1, circulating hot air blower 2, worm turbine fan, heating rod, one-way valve, drying plate 53, etc. in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the oven 1, circulating hot air blower 2, worm turbine fan and heating rod can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
