The outer surface of the top ring block 31 is penetrated by a locking screw 311. The shielding rubber plate 4 is an open thin rubber ring structure. By rotating the locking screw 311, the locking screw 311 penetrates the top end of the shielding rubber plate 4. The shielding rubber plate 4 is a split structure, and the shielding rubber plate 4 can be disassembled. Dust and dirt impurities adhere to the surface of the shielding rubber plate 4, and the shielding rubber plate 4 can be removed to facilitate cleaning the surface of the shielding rubber plate 4; a heat dissipation and exhaust mechanism, including a support plate 21 installed outside the support feet 11, an exhaust fan 22 installed on the support plate 21, and an air delivery pipe 23 with one end connected to the air inlet of the exhaust fan 22. The other end of the air delivery pipe 23 is communicated with the top ring block 31. The inside of the top ring block 31 is provided with an annular cavity 312. The support plate 21 and the support feet 11 are combined by a conventional method, and the exhaust fan 22 and the support plate 21 are combined by a conventional method. When the exhaust fan 22 operates, the air pressure between the outer shielding cylinder 32 and the polyurethane reaction kettle body 1 changes, and external air enters between the outer shielding cylinder 32 and the polyurethane reaction kettle body 1 and is sucked out by the exhaust fan 22. Under the action of the conventional heat conduction principle, the heat on the surface of the polyurethane reaction kettle body 1 is conducted to the inner heat-conducting copper tube 33, and under the action of the air flow, the heat is taken away, achieving the effect of facilitating heat dissipation.

[0026] In this embodiment, the inner heat-conducting copper tube 33 is in the shape of a spiral round tube, and the outer surface of the inner heat-conducting copper tube 33 is tangent to the outer surface of the polyurethane reaction kettle body 1. Under the action of the conventional heat conduction principle, the heat on the surface of the polyurethane reaction kettle body 1 is conducted to the inner heat-conducting copper tube 33, which is conducive to heat dissipation.

[0027] In this embodiment, a circular ring-shaped cavity is formed between the outer shielding cylinder 32 and the polyurethane reaction kettle body 1, and the inner heat-conducting copper tube 33 is distributed in the cavity. The annular cavity 312 is communicated with the cavity. A first through hole 321 communicated with the cavity is opened on the surface of the bottom end of the outer shielding cylinder 32. A dust-proof gauze 5 is adhered to the outside of the bottom end of the outer shielding cylinder 32. When the exhaust fan 22 sucks air, external air enters the inside of the outer shielding cylinder 32, and the dust-proof gauze 5 plays a role in filtering and dust prevention, reducing the dust impurities carried in the air.

[0028] In this embodiment, an annular limiting groove is provided on the bottom surface of the top ring block 31. The shielding rubber plate 4 is in clearance fit with the limiting groove. A round hole for the locking screw 311 to penetrate is provided at the top end of the shielding rubber plate 4. The locking screw 311 penetrates the top end of the shielding rubber plate 4. The shielding rubber plate 4 is of a split structure, and the shielding rubber plate 4 can be disassembled and assembled. Dust and dirt impurities adhere to the surface of the shielding rubber plate 4, and the shielding rubber plate 4 can be removed to facilitate cleaning the surface of the shielding rubber plate 4.

[0029] In this embodiment, a connecting pipe 61 is provided on the bottom surface of the outer shielding cylinder 32. An inner bottom cover 62 with an internal connection is provided at the bottom end of the connecting pipe 61. The connecting pipe 61, the outer shielding cylinder 32 and the bottom cover 62 are combined by conventional methods. A heat-conducting copper column 622 penetrates the inner surface of the bottom cover 62. The inner surface of the bottom cover 62 facing the bottom of the polyurethane reaction kettle body 1 is an inwardly concave curved surface. The surface of the bottom cover 62 facing the polyurethane reaction kettle body 1 fits. The heat-conducting copper column 622 contacts the outer surface of the polyurethane reaction kettle body 1. Under the action of the heat conduction principle, the heat on the surface of the polyurethane reaction kettle body 1 is conducted to the heat-conducting copper column 622, which is beneficial to heat dissipation. The connecting pipe 61 is of a hollow structure. An air storage cavity is provided inside the bottom cover 62. An air inlet hole 621 communicating with the air storage cavity is opened on the outer surface of the bottom cover 62. A communication hole 322 communicating with the connecting pipe 61 is provided at the bottom end of the outer shielding cylinder 32. When the exhaust fan 22 operates and sucks air, external air enters from the air inlet hole 621 and can take away the heat on the surface of the heat-conducting copper column 622.

[0030] The working principle and usage process of the present utility model:

[0031] When preparing polyurethane in the polyurethane reaction kettle, the outer shielding cylinder 32 shields the outer surface of the container of the polyurethane reaction kettle body 1 to prevent dust and dirt from accumulating and affecting heat dissipation.

[0032] The shielding rubber plate 4 is of an open thin rubber ring structure. The shielding rubber plate 4 is installed on the outside of the outer shielding cylinder 32. The locking screw 311 rotates so that the locking screw 311 penetrates the top end of the shielding rubber plate 4. The shielding rubber plate 4 is of a split structure, and the shielding rubber plate 4 can be disassembled and assembled. Dust and dirt impurities adhere to the surface of the shielding rubber plate 4, and the shielding rubber plate 4 can be removed to facilitate cleaning the surface of the shielding rubber plate 4.

[0033] The inner heat-conducting copper pipe 33 on the inner surface of the outer shielding cylinder 32 and the heat-conducting copper column 622 on the bottom cover 62 contact the outer surface of the polyurethane reaction kettle body 1. Under the action of the heat conduction principle, the heat on the surface of the polyurethane reaction kettle body 1 is conducted to the inner heat-conducting copper pipe 33 and the heat-conducting copper column 622, which is beneficial to heat dissipation.

[0034] When the exhaust fan 22 operates and sucks air, part of the air enters the inside of the outer shielding cylinder 32 from the first through hole 321. The dust-proof screen 5 plays a role in filtering and dust prevention, reducing the dust impurities carried in the air. The dust-proof screen 5 is also sleeved on the outside of the bottom end of the shielding rubber plate 4 to prevent the shielding rubber plate 4 from loosening.

[0035] The exhaust fan 22 operates, causing a change in the air pressure between the outer shielding cylinder 32 and the polyurethane reaction kettle body 1. External air enters between the outer shielding cylinder 32 and the polyurethane reaction kettle body 1 and is discharged after being sucked by the exhaust fan 22. Under the action of the conventional heat conduction principle, the heat on the surface of the polyurethane reaction kettle body 1 is conducted to the inner heat-conducting copper tube 33, and under the action of the air flow, the heat is taken away, achieving the effect of facilitating heat dissipation.

[0036] Similarly, when the exhaust fan 22 operates, external air enters from the air inlet hole 621 and can take away the heat on the surface of the heat-conducting copper column 622.

[0037] In summary: There is a design on the reaction kettle to prevent dust and dirt from contacting the reaction kettle body and facilitate heat dissipation on the surface of the kettle body. The outer shielding cylinder 32 and the shielding rubber plate 4 shield the outside of the polyurethane reaction kettle body 1, which can prevent dust and dirt from adhering to the outer surface of the polyurethane reaction kettle body 1. Under the action of the heat conduction principle, the heat on the surface of the polyurethane reaction kettle body 1 is conducted to the inner heat-conducting copper tube 33 and the heat-conducting copper column 622. The exhaust fan 22 operates and sucks air, and under the action of the air flow, the heat is taken away, achieving the effect of facilitating heat dissipation.
