Description

Technical Field

[0001] The present application relates to the technical field of drying equipment, and in particular to an air energy drying room for lost foam patterns. Background Art

[0002] In the process of producing lost foam patterns, it is necessary to first coat the surface of the produced mold with a coating, and then use equipment such as a drying room to dry the coated coating.

[0003] In the existing drying room, a number of electric heating wires are generally arranged evenly on the walls of the drying room. Then, a batch of molds to be dried are placed on the movable loading racks at intervals. Finally, the movable loading racks are pushed into the drying room and each electric heating wire is started, so as to dry the molds by heating the air in the drying room through the electric heating wires.

[0004] However, since the distances between the molds placed on the movable loading racks and the electric heating wires on the walls are not exactly the same, and the temperature is lower in the place farther away from the electric heating wires in the drying room, the longer the drying time required for the molds farther away from the electric heating wires will be. As a result, workers need to spend a long time waiting for all the molds in the same batch to be dried, and the drying efficiency is low.

[0005] In view of this, an air energy drying room for lost foam patterns is needed. Summary of the Utility Model

[0006] In order to solve the problem that the farther the mold in the drying room is from the electric heating wire, the longer the drying time required, and the low drying efficiency of the molds in the same batch, the present application provides an air energy drying room for lost foam patterns.

[0007] The present application provides an air energy drying room for lost foam patterns, adopting the following technical solutions: including a drying room body, a movable loading rack, a heating device and a heat equalizing component. The lost foam pattern can be placed on the movable loading rack. A passage door for the movable loading rack to pass through is provided on one side wall of the drying room body, and the heating device is provided on the inner wall surface of the other side wall of the drying room body;

[0008] The heat equalizing component includes a heat equalizing pipe and an air guiding device. An air inlet and an air outlet are provided on the heating device. The heat equalizing pipe is arranged at the junction of the inner wall surface and the ground of the drying room body. One end of the heat equalizing pipe is connected to the air outlet, the other end of the heat equalizing pipe is closed, and a number of heat equalizing holes are formed along the length direction of the pipe body of the heat equalizing pipe. The air guiding device is connected to the heat equalizing pipe. The gas in the drying room body can sequentially pass through the air inlet and the air outlet and be sucked by the air guiding device into the heat equalizing pipe and discharged from the heat equalizing holes of the heat equalizing pipe.

[0009] By adopting the above technical solution, after placing a batch of expendable patterns to be dried separately on the movable loading rack, the worker can first push the movable loading rack into the air energy drying room for expendable patterns through the access door, and then turn on the heating device and the air extraction device. The gas in the drying room body will first be sucked into the heating device by the air extraction device from the air inlet, so that the heating device can heat this part of the gas. The heated gas will continue to be sucked into the heat equalizing pipe by the air extraction device from the air outlet, and finally return to the drying room body from a number of heat equalizing holes opened on the heat equalizing pipe, so as to achieve uniform heating inside the drying room and avoid the situation that the time required to dry a certain expendable pattern is longer due to the lower temperature around individual expendable patterns, thereby making the air energy drying room for expendable patterns have a high drying efficiency for the same batch of expendable patterns.

[0010] Specifically, the movable loading rack is provided with multiple layers of partitions for placing expendable patterns, and a plurality of air permeable through holes are opened on each of the partitions, and movable rollers are provided at the bottom of the frame body of the movable loading rack.

[0011] By adopting the above technical solution, the setting of the air permeable through holes can increase the fluidity of the air between the upper and lower partitions, so that the temperature difference in the drying room is smaller; the setting of the movable rollers can facilitate the worker to move the movable loading rack.

[0012] Specifically, it further includes a turbulence fan, and the turbulence fan is arranged on the inner top wall of the drying room body.

[0013] By adopting the above technical solution, the turbulence fan can agitate the cold air at the top of the drying room body from top to bottom, so as to form a convection with the hot air ejected from the heat equalizing pipe from bottom to top, so that each area inside the drying room can be evenly heated and the temperature difference in the drying room is further reduced.

[0014] Specifically, a ventilation opening communicating with the outside is opened on the wall of the drying room body, and an exhaust fan is arranged in the ventilation opening.

[0015] By adopting the above technical solution, on the one hand, the water vapor and waste gas generated by the volatilization of the coating in the drying room can be discharged to the outside by the exhaust fan from the ventilation opening; on the other hand, the setting of the ventilation opening can also balance the air pressure inside and outside the drying room body and avoid the situation of pressure imbalance inside the drying room body.

[0016] Specifically, a filter screen is arranged in the air inlet of the heating device.

[0017] By adopting the above technical solution, the filter screen can block sundries such as dust and hair in the air, so that these sundries are not easy to enter and damage the heating device and the air extraction device, or enter the heat equalizing pipe to block the heat equalizing holes.

[0018] Specifically, it further includes a control component, and the control component includes a temperature sensor, a controller, and a human-machine interaction device. The temperature sensor is arranged inside the drying chamber body and can detect the temperature inside the drying chamber body. The temperature sensor is electrically connected to the controller and can feed back the detection result to the controller. The human-machine interaction device is arranged on the outer wall of the drying chamber body and is electrically connected to the controller. The heating device and the air guiding device are both electrically connected to the controller, and the controller can control the switches of the heating device and the air guiding device according to the signal of the human-machine interaction device.

[0019] By adopting the above technical solution, the temperature sensor can detect the temperature inside the drying chamber body and feed back the detection result to the controller. The controller is electrically connected to the human-machine interaction device, so that the worker can intuitively understand the temperature inside the drying chamber body through the human-machine interaction device and send a signal to the controller to turn on or off the heating device or the air guiding device, thereby controlling the switches of the heating device and the air guiding device through the controller.

[0020] Specifically, a folding corrugated section is provided in the middle of the pipe body of the heat equalizing pipe. The heat equalizing pipe between the folding corrugated section and the air guiding device is fixedly connected to the inner wall of the drying chamber body. One end of the heat equalizing pipe far from the air guiding device can rotate towards or away from the heating device via the folding corrugated section.

[0021] By adopting the above technical solution, the setting of the folding corrugated section enables one end of the heat equalizing pipe far from the air guiding device to rotate towards or away from the heating device, so that when there are fewer movable loading racks to be dried inside the drying chamber body, the worker can rotate the heat equalizing pipe to surround the periphery of the movable loading rack, thereby improving the drying efficiency of the lost foam on the movable loading rack.

[0022] Furthermore, a rolling support is provided at one end of the heat equalizing pipe far from the air guiding device. The heat equalizing pipe is arranged on the frame body of the rolling support, and moving rollers are provided at the bottom of the rolling support.

[0023] By adopting the above technical solution, the rolling support can slide on the ground through the arrangement of the moving rollers, so that it is convenient for the worker to bend or restore the heat equalizing pipe.

[0024] In summary, the present application includes the following beneficial technical effects:

[0025] It includes a drying room body, a movable loading rack, a heating device and a heat equalizing component. The expendable pattern can be placed on the movable loading rack. There is a passage door on one side wall of the drying room body for the movable loading rack to pass through, and a heating device is provided on the inner wall surface of the other side wall of the drying room body; the heat equalizing component includes a heat equalizing pipe and an air guiding device. The heating device is provided with an air inlet and an air outlet. The heat equalizing pipe is arranged at the junction of the inner wall surface and the ground of the drying room body. One end of the heat equalizing pipe is connected to the air outlet, the other end of the heat equalizing pipe is closed, and a number of heat equalizing holes are arranged along the length direction of the pipe body of the heat equalizing pipe. The air guiding device is connected to the heat equalizing pipe. The gas in the drying room body can sequentially pass through the air inlet and the air outlet and be sucked by the air guiding device into the heat equalizing pipe and discharged from the heat equalizing holes, so as to realize uniform heating inside the drying room, avoid the situation that the temperature around some expendable patterns is relatively low, resulting in a longer drying time required for these expendable patterns, and thus improve the drying efficiency of the air energy drying room for the expendable patterns of the same batch.

Detailed Description of the Embodiments

[0031] Figure 1 is a perspective view of the first embodiment of the present application, Figure 2 is a perspective view of the first embodiment of the present application, in which the top wall of the drying room body is removed. See Figure 1 and Figure 2, the first embodiment provided by this application includes: a drying chamber body 1, a movable loading rack 2, a heating device 3, and a heat equalizing assembly 4. The lost foam 5 can be placed on the movable loading rack 2. The cross-section of the drying chamber body 1 in the horizontal direction is rectangular.

See Figure 2 and Figure 3 , the heat equalizing assembly 4 includes four heat equalizing pipes 41 and two air guiding devices 42.

The gas in the drying chamber body 1 will first be sucked into the heating device 3 by the air guiding device 42 from the air inlet, so that the heating device 3 can heat this part of the gas. The heated gas will continue to be sucked into the heat equalizing pipes 41 by the air guiding device 42 from the air outlets, and finally return to the drying chamber body 1 from a number of heat equalizing holes 411 provided on the heat equalizing pipes 41, so as to realize the uniform heating of the inside of the drying chamber and avoid the situation that the time required for drying a certain lost foam 5 is longer due to the lower temperature around the individual lost foam 5, thereby making the air energy drying chamber for lost foams have a high drying efficiency for the lost foams of the same batch.

[0034] See Figure 2 and Figure 3, the movable loading rack 2 is provided with multiple layers of partitions 21 for placing the lost foam patterns 5. Each partition 21 is provided with a plurality of air-permeable through holes to increase the fluidity of the air between the upper and lower partitions 21, thereby making the temperature difference in the drying chamber smaller; the bottom of the frame body of the movable loading rack 2 is provided with movable rollers 22 to facilitate the workers to move the movable loading rack 2; a plurality of flow disturbance fans 6 are provided on the inner top wall of the drying chamber body 1. The flow disturbance fans 6 can agitate the cold air at the top of the drying chamber body 1 from top to bottom to form a convection with the hot air ejected upward from the heat equalizing pipe 41, so that each area inside the drying chamber can be evenly heated, further reducing the temperature difference in the drying chamber.

[0035] See Figure 2 and Figure 3 , a ventilation opening communicating with the outside is also provided on the wall of the drying chamber body 1. An exhaust fan 12 is provided in the ventilation opening. On the one hand, the water vapor and waste gas generated by the volatilization of the paint in the drying chamber can be discharged to the outside by the exhaust fan 12 from the ventilation opening; on the other hand, the setting of the ventilation opening can also balance the air pressure inside and outside the drying chamber body 1 to avoid the situation of pressure imbalance inside the drying chamber body 1; a filter screen 31 is provided in the air inlet of the heating device 3 to block sundries such as dust and hair in the air through the filter screen 31, so that these sundries are not easy to enter and damage the heating device 3 and the air induction device 42, or enter the heat equalizing pipe 41 to block the heat equalizing holes 411.

The human-computer interaction device 71 is arranged on the outer wall of the drying chamber body 1 and is electrically connected to the controller. The human-computer interaction device 71 can be a touch screen. Both the heating device 3 and the air induction device 42 are electrically connected to the controller; through the above settings, the temperature sensor can detect the temperature inside the drying chamber body 1 and feedback the detection result to the controller, and the controller is electrically connected to the human-computer interaction device 71, so that the worker can intuitively understand the temperature inside the drying chamber body 1 through the human-computer interaction device 71 and send a signal to turn on or off the heating device 3 or the air induction device 42 to the controller, thereby controlling the on and off of the heating device 3 and the air induction device 42 through the controller.

[0037] Figure 4 is a schematic cross-sectional view taken along the central axis of the drying chamber body in the length direction in the second embodiment of the present application. See Figure 4, the second embodiment provided by this application has basically the same structure as the first embodiment, and the same parts will not be described in detail. The difference lies in that: a folding corrugated section 412 is provided in the middle of the tube bodies of the two equalizing heat pipes 41 on the same side of the drying chamber body 1. The equalizing heat pipe 41 between the folding corrugated section 412 and the air guiding device 42 is fixedly connected to the inner wall of the drying chamber body 1. One end of the equalizing heat pipe 41 far from the air guiding device 42 can rotate towards or away from the heating device 3 via the folding corrugated section 412, so that one end of the equalizing heat pipe 41 far from the air guiding device 42 can rotate towards or away from the heating device 3, so that when there are fewer movable loading racks 2 to be dried in the drying chamber body 1, for example, only two movable loading racks 2, the worker can surround the periphery of the movable loading rack 2 by rotating the equalizing heat pipe 41, thereby improving the drying efficiency of the lost foam 5 on the movable loading rack 2; a rolling support 413 is provided at one end of the equalizing heat pipe 41 far from the air guiding device 42.

[0039] After placing a batch of lost foams 5 to be dried separately on the movable loading rack 2, the worker can first push the movable loading rack 2 into the air energy drying chamber for lost foam from the access door 11, and then turn on the heating device 3 and the air guiding device 42. The gas in the drying chamber body 1 will first be sucked into the heating device 3 from the air inlet by the air guiding device 42, so that the heating device 3 can heat this part of the gas. The heated gas will continue to be sucked into the equalizing heat pipe 41 from the air outlet by the air guiding device 42, and finally return to the drying chamber body 1 from a number of heat equalizing holes 411 provided on the equalizing heat pipe 41, so as to realize uniform heating inside the drying chamber and avoid the situation that the lost foam 5 needs a longer time to be dried due to the lower temperature around individual lost foams 5, thereby making the air energy drying chamber for lost foam have a high drying efficiency for the lost foams 5 of the same batch.
