Description

Technical Field

[0001] This utility model relates to the field of radiation-cooled coating processing technology, and in particular to a disperser for radiation-cooled coating processing. Background Technology

[0002] In the processing of radiation cooling coatings, the disperser plays a crucial role, directly affecting the performance and quality of the coating. Radiation cooling coatings are usually composed of a variety of components, including pigments, fillers, functional particles, and various additives. Among them, the uniform dispersion of pigments and fillers is a key factor in ensuring the color consistency and hiding power of the coating.

[0003] During the process of stirring and dispersing radiation cooling coatings, functional particles (such as titanium dioxide and silicon dioxide) have a high density and are prone to settling and accumulating at the bottom of the disperser shell under gravity when stationary. When the stirring device starts to operate, areas with weak fluid shear force, such as the center and corners at the bottom of the tank, are prone to forming mixing dead zones, making it difficult for functional particles to be fully incorporated into the main flow field and resulting in insufficient participation in mixing, thus reducing the dispersion effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the weak fluid shear force areas at the bottom center and edge corners of the tank, which easily form mixing dead zones, making it difficult for functional particles to be fully incorporated into the main flow field and resulting in insufficient participation in mixing, thus reducing the dispersion effect. Therefore, this invention proposes a disperser for radiation-cooled coating processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a disperser for radiation-cooled coating processing, comprising a housing, a motor mounted on the upper end of the housing, the output end of the motor extending into the housing and fixedly connected to several dispersing discs, a support frame at the bottom end of the housing, a support plate fixedly connected to one side of the housing, a liquid pump mounted on the upper end of the support plate, a first connecting pipe connected to the inlet end of the liquid pump, one end of the first connecting pipe connected to the bottom end of one side of the housing, and a circular annular pipe connected to the outlet end of the liquid pump via a second connecting pipe, a discharge pipe connected to the circular annular pipe, one end of the discharge pipe extending into the housing.

[0007] Preferably, the support frame includes a fixing ring, which is fixedly connected to the housing. The bottom end of the fixing ring is connected with a plurality of connecting plates at equal intervals along the axis, and the bottom end of each connecting plate is fixedly connected with a support block.

[0008] Preferably, the connecting plate and the support block are in an integral structure.

[0009] Preferably, each of the support blocks has an anti-slip pad fixedly connected to its bottom end.

[0010] Preferably, the discharge pipe is provided with several pipes that are evenly distributed along the axis of the annular pipe.

[0011] Preferably, the bottom of the housing is provided with several baffles at equal intervals along the axial direction.

[0012] Preferably, a heat dissipation mechanism is fixedly connected to the housing. The heat dissipation mechanism includes a hollow frame, which is fixedly connected to the housing. The upper end of the hollow frame has a liquid inlet, and the bottom end of the hollow frame has a liquid outlet. A plurality of heat dissipation fins are connected at equal intervals along the axial direction on the hollow frame.

[0013] Preferably, the hollow frame is a stainless steel frame.

[0014] The dispersion machine for radiation-cooled coating processing proposed in this utility model has the following advantages:

[0015] The coating material at the bottom of the shell is extracted through the first connecting pipe. The extracted coating material is then introduced into the annular pipe through the second connecting pipe. The coating material in the annular pipe is released from several discharge pipes. The released coating material flows down from the top again. During the operation of the pump, the heavy particles at the bottom are continuously transported to the upper part of the shell for recirculation, avoiding dead zones at the bottom and improving the dispersion effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A disperser for processing radiation-cooled coatings includes a housing 1, with a feed pipe 2 connected to the upper end of the housing 1 and a discharge pipe 3 connected to the bottom end of the housing 1. A motor 4 is installed at the upper end of the housing 1, and the output end of the motor 4 extends into the housing 1 and is fixedly connected to several dispersing discs 5. A support frame 6 is provided at the bottom end of the housing 1, and a support plate 7 is fixedly connected to one side of the housing 1. A liquid pump 8 is installed at the upper end of the support plate 7. The inlet end of the liquid pump 8 is connected to a first connecting pipe 9, and one end of the first connecting pipe 9 is connected to the bottom end of one side of the housing 1. The outlet end of the liquid pump 8 is connected to a circular annular pipe 11 through a second connecting pipe 10. A discharge pipe 12 is connected to the circular annular pipe 11, and one end of the discharge pipe 12 extends into the housing 1. Several discharge pipes 12 are provided and are evenly distributed along the axis of the circular annular pipe 11. Several baffles 13 are evenly distributed along the axis at the bottom of the interior of the housing 1.

[0023] Work process:

[0024] The coating is introduced into the housing 1 through the feed pipe 2. After the motor 4 is started, it drives several dispersing discs 5 to rotate. After the several dispersing discs 5 rotate, they stir and disperse the coating in the housing 1. The rotating coating collides with the baffle 13. The baffle 13 breaks the overall vortex and increases the radial and axial movement of the coating, making the mixing more thorough.

[0025] At the same time, after the liquid pump 8 is powered on and started, it draws the coating from the bottom of the shell 1 through the first connecting pipe 9. The drawn coating is introduced into the annular pipe 11 through the second connecting pipe 10. The coating in the annular pipe 11 is released from several discharge pipes 12. The released coating flows down from the top again. During the operation of the liquid pump 8, the heavy particles at the bottom are continuously transported to the upper part of the shell 1 for recirculation and processing, avoiding dead corners at the bottom and improving the dispersion effect.

[0026] Example 2: When supporting the housing 1, the equipment is prone to slippage during operation. (Refer to...) Figure 2-3 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the support frame 6 includes a fixing ring 61, which is fixedly connected to the housing 1. The bottom end of the fixing ring 61 is connected with several connecting plates 62 at equal intervals along the axis. The bottom end of each connecting plate 62 is fixedly connected with a support block 63. The connecting plate 62 and the support block 63 are in an integral structure. The bottom end of each support block 63 is fixedly connected with an anti-slip pad 64. The support block 63 supports the fixing ring 61 through the connecting plate 62. The fixing ring 61 supports the housing 1. The support block 63 contacts the ground through the anti-slip pad 64. The anti-slip pad 64 increases the friction between the support block 63 and the ground, making it less likely for the device to slide during operation.

[0027] Example 3: When the dispersing disc 5 rotates to shear and disperse the liquid, a large amount of mechanical energy is converted into heat energy, causing the temperature of the liquid to rise and reducing the dispersion effect. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a heat dissipation mechanism 14 is fixedly connected to the shell 1. The heat dissipation mechanism 14 includes a hollow frame 141, which is fixedly connected to the shell 1. The hollow frame 141 is a stainless steel frame. The upper end of the hollow frame 141 is provided with a liquid inlet 142, and the bottom end of the hollow frame 141 is provided with a liquid outlet 143. A plurality of heat dissipation fins 144 are connected at equal intervals along the axis of the hollow frame 141.

[0028] Cooling water is introduced into the hollow frame 141 through the liquid inlet 142. The cooling water comes into contact with the shell 1, and the heat in the liquid is transferred to the cooling water through the shell 1 to cool the liquid in the shell 1. The heat dissipation fins 144 cool the cooling water in the hollow frame 141.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
