AI Technical Summary
In order to maintain the stability of the temperature inside the drying channel, existing motor-driven drying devices need to continuously discharge excessive hot air, resulting in energy waste.
The system employs a drying channel, heating chamber, and T-junction pipe structure. A fan delivers a mixture of heated and unheated air into the heating chamber. The T-junction pipe design allows the heated air to re-enter the heating chamber, reducing the emission of unheated air.
This approach achieves energy savings and reduces energy consumption while maintaining stable temperature in the drying channel.

Abstract
Description
Technical Field
[0001] This application relates to the field of processing equipment technology, and in particular to a motor drying device. Background Technology
[0002] During the production of motors, the motors must be dried using a motor drying device both before and after painting to ensure the quality of the paint application as much as possible.
[0003] Current motor drying equipment includes interconnected drying channels and heating boxes. The drying channels are used to hold the motors to be dried, and the heating boxes are used to supply heated air to the drying channels until the motors in the drying channels are dried.
[0004] However, during the drying process, in order to maintain the stability of the temperature inside the drying channel as much as possible, the heating box usually needs to continuously supply heated air to the drying channel. When there is excess hot air inside the drying channel, it is directly discharged outside the drying channel, resulting in energy waste. Utility Model Content
[0005] In view of this, the motor drying device provided in this application can save energy.
[0006] This application provides a motor drying device, which includes: a drying channel, a heating chamber, and a three-way pipe; the drying channel provides space for the motor to be dried; a fan is connected to the air inlet of the heating chamber, and an output pipe connects the air outlet of the heating chamber to the drying channel; the heating chamber is configured to supply air into the heating chamber via the fan, and to deliver the heated air to the drying channel via the output pipe to dry the motor located in the drying channel; the first end of the three-way pipe is connected to the output pipe, the second end of the three-way pipe is connected to the air inlet of the fan, and the third end of the three-way pipe is suspended outside the heating chamber.
[0007] In one possible implementation, the tee pipe includes a first pipe, a second pipe, and a third pipe. A first end of the first pipe is the first end of the tee pipe, a first end of the second pipe is the second end of the tee pipe, and a first end of the third pipe is the third end of the tee pipe. The second ends of the first pipe, the second pipe, and the third pipe are interconnected. A first proportional valve is provided on the first pipe, which regulates the first amount of air delivered from the first pipe to the second pipe under the action of the fan. A second proportional valve is provided on the third pipe, which regulates the second amount of air delivered from the third pipe to the second pipe under the action of the fan.
[0008] In one possible implementation, during the operation of the motor drying device, the first air volume is greater than the second air volume.
[0009] In one possible implementation, during the operation of the motor drying device, the first air volume is 80% to 90% of the total air volume in the second duct, and the second air volume is 10% to 20% of the total air volume in the second duct.
[0010] In one possible implementation, the drying channel is positioned above the heating chamber.
[0011] In one possible implementation, a guide pipe is provided inside the drying channel; the length direction of the guide pipe is parallel to the length direction of the drying channel, the first end of the output pipe is connected to the air outlet of the heating box, the second end of the output pipe is connected to the guide pipe, and multiple air vents are provided on the guide pipe, the air vents penetrate the pipe wall of the guide pipe, and the multiple air vents are distributed sequentially along the length direction of the guide pipe.
[0012] In one possible implementation, the guide pipe is located at the bottom of the drying channel.
[0013] In one possible implementation, the vent is located at the top of the flow channel.
[0014] In one possible implementation, the motor drying device further includes a transmission pipe, a first end of which is connected to the output pipe, and a second end of which is connected to another output pipe included in the motor drying device.
[0015] In one possible implementation, a filter screen is provided inside the heating box, which divides the combustion chamber inside the heating box into a first chamber and a second chamber; the air inlet of the heating box is connected to the first chamber, and the air outlet of the heating box is connected to the second chamber.
[0016] As can be seen from the above technical solution, the motor drying device includes a drying channel, a heating chamber, and a three-way pipe. The drying channel provides space for the motor to be dried. The heating chamber heats the air supplied by the fan and then supplies it to the drying channel through an output pipe. The first end of the three-way pipe is connected to the conveying pipe, the second end is connected to the air inlet of the fan, and the third end is suspended outside the heating chamber. Therefore, during the use of the motor drying device, part of the air supplied by the fan to the heating chamber comes from the first end of the three-way pipe, and the other part comes from the third end. That is, part of the air supplied by the fan to the heating chamber is heated air from the conveying pipe, and the other part is unheated air from outside the heating chamber. Compared to a solution that only supplies unheated air from outside the heating chamber to the heating chamber via a fan, in this application, a portion of the heated air can re-enter the heating chamber, which hardly affects the temperature stability within the drying channel, thus achieving energy savings.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0026] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0027] As mentioned earlier, during the production of motors, the motors must be dried by a motor drying device both before and after painting to ensure the quality of the paint. Current motor drying devices consist of interconnected drying channels and heating boxes. The drying channels hold the motors to be dried, and the heating boxes supply heated air to the drying channels until the motors are completely dried. However, during the drying process, in order to maintain the stability of the temperature within the drying channels, the heating boxes usually continuously supply heated air to the drying channels. Excess hot air in the drying channels is then directly discharged outside, resulting in energy waste.
[0028] In this embodiment, the motor drying device includes a drying channel, a heating chamber, and a three-way pipe. The drying channel provides space for the motor to be dried. The heating chamber heats the air supplied by the fan and then supplies it to the drying channel through an output pipe. The first end of the three-way pipe is connected to the conveying pipe, the second end is connected to the air inlet of the fan, and the third end is suspended outside the heating chamber. Therefore, during the use of the motor drying device, part of the air supplied by the fan to the heating chamber comes from the first end of the three-way pipe, and the other part comes from the third end. That is, part of the air supplied by the fan to the heating chamber is heated air from the conveying pipe, and the other part is unheated air from outside the heating chamber. Compared to a scheme that only supplies unheated air from outside the heating chamber to the heating chamber via a fan, in this application, a portion of the heated air can re-enter the heating chamber, which hardly affects the temperature stability within the drying channel, thus achieving energy savings.
[0029] The motor drying device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0030] Figure 1 This is a schematic diagram of the structure of a motor drying device provided in one embodiment of this application. Figure 1As shown, the motor drying device includes: a drying channel 1, a heating chamber 2, and a three-way pipe 3; the drying channel 1 provides space for the motor to be dried; a fan 21 is connected to the air inlet of the heating chamber 2, and an output pipe 22 connects the air outlet of the heating chamber 2 to the drying channel 1. The heating chamber 2 is configured to supply air into the heating chamber 2 through the fan 21, and to deliver the heated air to the drying channel 1 through the output pipe 22 to dry the motor located in the drying channel 1; the first end of the three-way pipe 3 is connected to the output pipe 22, the second end of the three-way pipe 3 is connected to the air inlet of the fan 21, and the third end of the three-way pipe 3 is suspended outside the heating chamber 2.
[0031] In this embodiment, the motor drying device includes a drying channel 1, a heating chamber 2, and a three-way pipe 3. The drying channel 1 provides space for the motor to be dried. The heating chamber 2 heats the air supplied by the fan 21 and then supplies it to the drying channel 1 through the output pipe 22. The first end of the three-way pipe 3 is connected to the conveying pipe, the second end is connected to the air inlet of the fan 21, and the third end is suspended outside the heating chamber 2. Thus, during the use of the motor drying device, part of the air supplied by the fan 21 to the heating chamber 2 comes from the first end of the three-way pipe 3, and the other part comes from the third end of the three-way pipe 3. That is, part of the air supplied by the fan 21 to the heating chamber 2 is the heated air inside the conveying pipe, and the other part is the unheated air outside the heating chamber 2. Compared with the scheme of only supplying the unheated air outside the heating chamber 2 to the heating chamber 2 through the fan 21, in this application, a portion of the heated air can re-enter the heating chamber 2, which hardly affects the temperature stability inside the drying channel 1, thus achieving the purpose of energy saving.
[0032] In one possible implementation, such as Figure 1 As shown, the drying channel 1 is located above the heating box 2.
[0033] In one specific embodiment, the drying channel 1 can be a transverse channel with openings at both ends, which is located above the heating box 2. A motor suspension chain with multiple motors is circulated from the first end of the drying channel 1 and exits from the second end of the drying channel 1.
[0034] Therefore, the heating box 2 can deliver the heated air upward to the drying channel 1 through the output pipe 22, which is more in line with the physical phenomenon that hot air rises, saves the power of transportation, and saves energy.
[0035] In one possible implementation, such as Figure 1As shown, a guide pipe 11 is provided in the drying channel 1; the length direction of the guide pipe 11 is parallel to the length direction of the drying channel 1, the first end of the output pipe 22 is connected to the air outlet of the heating box 2, the second end of the output pipe 22 is connected to the guide pipe 11, and multiple air vents 111 are provided on the guide pipe 11. The air vents 111 penetrate the pipe wall of the guide pipe 11, and the multiple air vents 111 are distributed along the length direction of the guide pipe 11.
[0036] Therefore, the conveying pipe is connected to the drying channel 1 through the guide pipe 11 and the air vents 111 opened on the guide pipe 11. The heated air in the conveying pipe flows into the drying channel 1 through the air vents 111 on the guide pipe 11, which can make the heated air more uniform in the drying channel 1.
[0037] In one possible implementation, such as Figure 1 As shown, the guide pipe 11 is located at the bottom of the drying channel 1. Thus, the heated air flowing out of the air vent 111 in the guide pipe 11 can flow from bottom to top in the drying channel 1, which avoids the occurrence of too much hot air at the air vent 111, so as to make the heated air in the drying channel 1 more evenly distributed.
[0038] In one possible implementation, such as Figure 1 As shown, the vent 111 is located at the top of the guide pipe 11. Thus, the heated air in the vent 111 flows into the drying channel 1 in a way that conforms to the physical phenomenon that hot air rises, saving transport power and energy.
[0039] In one possible implementation, such as Figure 1 As shown, a filter plate 23 is provided inside the heating box 2. The filter plate 23 divides the combustion chamber inside the heating box 2 into a first chamber and a second chamber. The air inlet of the heating box 2 is connected to the first chamber, and the air outlet of the heating box 2 is connected to the second chamber. Thus, the filter plate 23 can reduce the amount of impurities in the heated air delivered from the heating box 2.
[0040] Optionally, such as Figure 1 As shown, the filter screen 23 can be detachably connected inside the heating box 2 for easy replacement or cleaning.
[0041] In one possible implementation, such as Figure 1 As shown, the tee pipe 3 includes a first pipe 31, a second pipe 32, and a third pipe 33. The first end of the first pipe 31 is the first end of the tee pipe 3, the first end of the second pipe 32 is the second end of the tee pipe 3, and the first end of the third pipe 33 is the third end of the tee pipe 3. The second ends of the first pipe 31, the second end of the second pipe 32, and the second end of the third pipe 33 are interconnected. Based on this:
[0042] A first proportional valve 311 is installed on the first pipe 31, which regulates the first air volume delivered from the first pipe 31 to the second pipe 32 under the action of the fan 21; a second proportional valve 331 is installed on the third pipe 33, which regulates the second air volume delivered from the third pipe 33 to the second pipe 32 under the action of the fan 21.
[0043] In this embodiment, the first proportional valve 311 can control the first air volume of heated air delivered to the heating box 2 by the fan 21, and the second proportional valve 331 can control the second air volume of unheated air delivered to the heating box 2 by the fan 21. Thus, the first air volume and the second air volume can be adjusted according to actual needs, thereby improving the applicability of the motor drying device.
[0044] In one possible implementation, such as Figure 1 As shown, during the operation of the motor drying device, the first air volume is greater than the second air volume. As a result, more heated air is delivered into the heating box 2 than unheated air, which makes the heating box 2 more efficient in heating air and saves more energy.
[0045] In one possible implementation, such as Figure 1 As shown, during the operation of the motor drying device, the first air volume is 80% to 90% of the total air volume in the second pipe 32, and the second air volume is 10% to 20% of the total air volume in the second pipe 32. For example, the first air volume is 85% of the total air volume in the second pipe 32, and the second air volume is 15% of the total air volume in the second pipe 32.
[0046] Therefore, the amount of heated air and unheated air supplied to the heating chamber 2 is appropriate, which can ensure that there is enough heated air entering the drying channel 1 while saving energy.
[0047] In one possible implementation, such as Figure 1 As shown, the motor drying device also includes a transmission pipe 4. The first end of the transmission pipe 4 is connected to the output pipe 22, and the second end of the transmission pipe 4 is connected to the output pipe 22 of another motor drying device. Thus, different motor drying devices can be connected in series through the transmission pipe 4 so that the temperature in the drying channel 1 of different motor drying devices is almost the same.
[0048] For the motor drying device of this application, with the air volume of fan 21 being 900 m³ / h... 3 / H, The first air volume is 85% of the total air volume in the second pipe 32 (i.e., the first air volume is 765M). 3Taking the following calculations as an example: the second air volume is 15% of the total air volume in the second pipe 32; the temperature of the air heated by the heating box 2 is set to 70℃; the current average ambient temperature (room temperature) is set to 20℃ (i.e., the temperature difference is 50℃); and the specific heat of air is 1.007KJ / (KG·K): the heat saved by the motor drying device of this application is Q=1.007*765*1.29*50=49687KJ=49.7MJ / H, and the calorific value of the gas is approximately 48MJ / M 3 The estimated gas savings are 1M 3 / H, taking a production line with two shifts, each shift operating for 80% of the time, and 22 days per month as an example, the annual gas savings for the motor drying unit are calculated as: 16 * 0.8 * 22 * 12 * 1 = 3379 * 4 yuan / M 3 =13,516 yuan / year. It can be seen from this that the motor drying device in this application is more energy-efficient and cost-effective.
