[0001] The invention relates to the field of chemistry, in particular to a fluidized coating technology, in particular to an epoxy powder fluidized device. Background Art

[0002] With the development of new energy vehicle motors, flat copper wire motors are being used more and more widely. In addition to using varnish to impregnate the motor stator, insulating materials are also needed to insulate the solder joints.

[0003] For the insulation treatment of armature welds, the conventional treatment method at home and abroad is to use epoxy powder coating process, in which epoxy powder is a thermosetting, non-toxic coating, which forms a high molecular weight cross-linked structure coating after curing, and has excellent chemical corrosion resistance and high mechanical properties, especially wear resistance and adhesion. The coating is 100% solid, solvent-free, pollution-free, and the powder utilization rate can reach more than 95%. When using epoxy powder coating process for insulation treatment of armature welds, the epoxy powder needs to be fluidized first. The phenomenon that solid particles show a fluid-like state under the action of fluid is called fluidization, that is, fluidization. The difficulty of this process is that the epoxy powder is fluidized through a fluidizing trough (barrel), and the powder height is difficult to control, resulting in inconsistent product coating height during the manufacturing process. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an epoxy powder fluidizing device for solving the problem of inconsistent powder fluidizing height in the prior art epoxy powder fluidizing device, which in turn causes inconsistent product coating height.

[0005] To achieve the above-mentioned purpose and other related purposes, the present invention provides an epoxy powder fluidization device, comprising: a fluidizing trough; the interior of the fluidizing trough is filled with epoxy powder, and a fluidized bed is horizontally arranged inside the fluidizing trough, and the fluidized bed is used to fluidize the epoxy powder; one end of the fluidizing trough is connected to an air pipe, and a pressure regulating valve is arranged on the air pipe, and the pressure regulating valve is used to adjust the air pressure in the fluidizing trough; an overflow port is arranged on the side wall of the fluidizing trough, and the overflow port is used to ensure that the height of the epoxy powder fluidized in the fluidizing trough is consistent; the lower end of the fluidizing trough is provided with a vibration component.

[0006] In one embodiment of the present invention, one end of the fluidizing tank is connected to the air pipe via an air pipe joint.

[0007] In one embodiment of the present invention, the overflow port is connected to a powder recovery component.

[0008] In one embodiment of the present invention, the ratio of the area of ​​the vertical cross section of the fluidizing tank to the area of ​​the radial cross section of the air pipe is 50-200.

[0009] Further, the overflow port is located above the fluidized bed.

[0010] Furthermore, the connection port between the fluidizing tank and the air pipe is located below the fluidized bed.

[0011] As described above, the epoxy powder fluidizing device of the present invention has the following beneficial effects:

[0012] (1) A pressure regulating valve is used to control the air pressure in the fluidizing tank to achieve stability of the air pressure in the fluidizing tank and meet the fluidization requirements;

[0013] (2) Compared with the existing technology, the fluidizing tank is designed with the overflow principle. By opening an overflow port on the tank wall, the consistency of fluidization height is ensured, thereby ensuring the consistency of height during subsequent coating and improving the coating quality of the product;

[0025] The following describes the implementation of the present invention through specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0026] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0027] The epoxy powder fluidizing device of the present invention is used to solve the problem of inconsistent powder fluidizing height in the epoxy powder fluidizing device in the prior art, which further causes inconsistent product coating height.

[0028] The principle and implementation mode of an epoxy powder fluidizing device of the present invention will be described in detail below, so that those skilled in the art can understand the epoxy powder fluidizing device of the present invention without creative work.

[0029] See also Figure 1 The epoxy powder fluidizing device provided in this embodiment adopts a pressure regulating valve to control the air pressure in the fluidizing tank, so as to achieve the stability of the air pressure in the fluidizing tank and meet the fluidization requirements; compared with the prior art, the fluidizing tank is designed with the overflow principle, and the overflow port is opened on the tank wall to ensure the consistency of the fluidization height, thereby ensuring the consistency of the height during subsequent coating and improving the coating quality of the product; by adding a vibration component, the powder can be fluidized more evenly and smoothly during the fluidization process, and the generation of local bubbles is reduced, which effectively improves the effect of the epoxy powder after fluidization, thereby improving the coating quality of the product.

[0030] like Figure 1 As shown, in one embodiment, the epoxy powder fluidizing device of the present invention comprises a fluidizing tank 1 .

[0031] Specifically, the interior of the fluidizing tank 1 is filled with epoxy powder 2 , and a fluidizing bed 3 is horizontally arranged inside the fluidizing tank 1 , and the fluidizing bed 3 is used to fluidize the epoxy powder 2 .

[0032] One end of the fluidizing tank 1 is connected to an air pipe 4 , and a pressure regulating valve 5 is provided on the air pipe 4 . The pressure regulating valve 5 is used to adjust the air pressure in the fluidizing tank 1 .

[0033] Specifically, the air pipe 4 is connected to the fluidizing tank 1 , and one end of the air pipe 4 away from the fluidizing tank 1 is connected to an air pressure pump (not shown in the figure), which adjusts the air pressure in the fluidizing tank 1 by controlling the pressure regulating valve 5 .

[0034] In one embodiment, one end of the fluidizing tank 1 is connected to the air pipe 4 via an air pipe joint 8 .

[0035] It should be noted that the air pipe 4 can be connected to the fluidizing tank 1 in an integrated manner, or the air pipe 4 can be connected to the fluidizing tank 1 through an air pipe joint 8 .

[0036] An overflow port 6 is provided on the side wall of the fluidizing tank 1 , and the overflow port 6 is used to ensure that the height of the epoxy powder 2 fluidized in the fluidizing tank 1 is consistent.

[0037] Specifically, an overflow port 6 is provided at a certain height on the side wall of the fluidizing tank 1. When the filling height of the epoxy powder 2 in the fluidizing tank 1 reaches the plane height where the overflow port is located, the epoxy powder 2 in the fluidizing tank 1 will overflow from the overflow port 6, while the filling height of the epoxy powder 2 in the fluidizing tank 1 is maintained at the plane height where the overflow port 6 is located. In this way, the fluidization height of the epoxy powder 2 in the fluidizing tank 1 can be ensured to be consistent and always at the plane height where the overflow port 6 is located, thereby ensuring that when subsequent products are coated, the coating height is also maintained at the plane height where the overflow port 6 is located, thereby ensuring the consistency of the product coating height, thereby improving the product coating quality.

[0038] It should be noted that the height setting of the overflow port 6 on the side wall of the fluidizing tank 1 depends on the actual application requirements. In different application scenarios, the height of the overflow port 6 on the side wall of the fluidizing tank 1 may be the same or different. The height position of the overflow port 6 on the side wall of the fluidizing tank 1 is not used as a condition to limit the present invention, and therefore, its setting height is not specifically limited.

[0039] In one embodiment, the overflow port 6 is connected to a powder recovery component.

[0040] It should be noted that the powder recovery assembly is provided to recover and reuse the epoxy powder overflowing from the overflow port 6, thereby reducing the waste of epoxy powder.

[0041] Furthermore, the powder recovery component is a common recovery structure in the art, and any structure that can achieve the recovery function is within the protection scope of the present invention.

[0042] Typically, the powder recovery component includes a recovery pipe and a recovery tank. One end of the recovery pipe is connected to the overflow port 6, and the other end is connected to the recovery tank. The epoxy powder overflowing from the overflow port 6 is recovered into the recovery tank through the recovery pipe.

[0043] A vibration assembly 7 is provided at the lower end of the fluidizing tank 1 .

[0044] Specifically, during the fluidization of the epoxy powder 2 by the fluidized bed 3, the vibration component 7 vibrates and drives the fluidizing trough 1 to vibrate, making the epoxy powder fluidized more uniformly and smoothly, and reducing the generation of local bubbles between the epoxy powders 2 in the fluidizing trough 1, effectively improving the effect of the epoxy powder 2 after fluidization, and thus improving the coating quality of the product.

[0045] It should be noted that the vibration component is a common recovery structure in the art, and any structure that can achieve the vibration function is within the protection scope of the present invention.

[0046] Typically, the vibration assembly includes a vibration plate and a vibration motor. The fluidizing tank 1 is disposed on the vibration plate. The vibration motor is started to drive the vibration plate to vibrate, thereby driving the fluidizing tank 1 to vibrate.

[0047] In one embodiment, the ratio of the area of ​​the vertical cross section of the fluidizing tank 1 to the area of ​​the radial cross section of the air pipe 4 is 50 to 200.

[0048] It should be noted that the size of the air pressure in the fluidizing tank 1 depends on the control action of the regulating valve 5, and the speed of the air pressure regulation process in the fluidizing tank 1 depends on the ratio of the area of ​​the vertical cross section to the area of ​​the radial cross section of the air pipe 4; the larger the area ratio, the greater the gap between the fluidizing tank 1 and the air pipe 4, and the slower the air pressure regulation; conversely, the smaller the area ratio, the smaller the gap between the two, and the faster the air pressure regulation.

[0049] In summary, the epoxy powder fluidizing device of the present invention adopts a pressure regulating valve to control the air pressure in the fluidizing tank, thereby achieving the stability of the air pressure in the fluidizing tank and meeting the fluidization requirements; compared with the prior art, the fluidizing tank is designed with an overflow principle, and an overflow port is opened on the tank wall to ensure the consistency of the fluidization height, thereby ensuring the consistency of the height during subsequent coating and improving the coating quality of the product; by adding a vibration component, the powder can be fluidized more evenly and smoothly during the fluidization process, and the generation of local bubbles is reduced, which effectively improves the effect of the epoxy powder after fluidization, thereby improving the coating quality of the product; therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.

[0050] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
