Description

Technical Field

[0001] The utility model relates to the technical field of adhesive production, in particular to an adhesive production cooling device. Background Art

These systems typically utilize water or other cooling media to absorb the heat, thereby keeping production equipment within a safe and efficient operating temperature range.

[0003] In conjunction with publication number CN220250449U, publication date 2023-12-26, an auxiliary cooling device for adhesive production is disclosed.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a cooling device for producing an adhesive comprises:

[0026] The cylinder wall 1 includes an outer wall and a ventilation pipe 11 passing through the axis. A cooling circuit 13 for circulating condensate is provided inside the cylinder wall 1;

[0027] A circulating pump 5 is provided on the cooling circuit 13;

[0028] A plurality of heat conducting plates 4 are provided on the inner wall of the ventilation pipe 11 . The first ends of the heat conducting plates 4 extend toward the cooling circuit 13 , and a plurality of through holes for ventilation are provided on the heat conducting plates 4 .

[0029] Specifically, a feed port and a discharge port are provided on the cylinder wall 1 , and the cylinder wall 1 is made of a heat-insulating material, and the heat-conducting plate 4 is in a circular ring structure.

[0030] Furthermore, when the temperature inside the cylinder begins to rise, the circulation pump 5 is started, so that the condensate in the cooling circuit 13 begins to circulate in the direction of the outer wall - ventilation pipe 11 - circulation pump 5 - outer wall. After the condensate moving along the ventilation pipe 11 absorbs heat, due to the setting of the heat conducting plate 4, the heat in the cooling circuit 13 is transferred to one end of the heat conducting plate 4 and transferred to the outside through the other end of the heat conducting plate 4, and heat exchange is performed with the external air. Since the ventilation pipe 11 is a through structure, the temperature of the air inside the ventilation pipe 11 rises after absorbing heat, and the hot air flows upward, causing air flow inside the ventilation pipe 11, reducing the temperature inside part of the cylinder. At the same time, the wind flows through the through holes on the heat conducting plate 4, further taking away the heat on the heat conducting plate 4, thereby playing a cooling role.

[0031] In the above technology, due to the setting of the heat conducting plate 4, the heat in the cooling circuit 13 is transferred to one end of the heat conducting plate 4 and transferred to the outside through the other end of the heat conducting plate 4, exchanging heat with the external air, and through the through structure of the ventilation pipe 11, air flow is generated inside the ventilation pipe 11, thereby reducing the temperature inside part of the cylinder.

[0032] As an embodiment further provided by the present invention, a blowing mechanism 3 is provided on the ventilation pipe 11 .

[0033] Specifically, the blowing mechanism 3 faces the ventilation pipe 11, and the blowing mechanism 3 is started to blow air into the ventilation pipe 11, thereby increasing the wind speed in the ventilation pipe 11, and the wind flows through the heat conducting plate 4 and takes away the heat on the heat conducting plate 4, thereby improving the cooling efficiency.

[0034] As another embodiment further provided by the present invention, the ventilation pipe 11 includes a straight cylindrical portion and a bucket-shaped portion 12 according to its shape. A blast chamber 2 is provided in the bucket-shaped portion 12 , and the blast mechanism 3 is located in the blast chamber 2 .

[0035] Specifically, an air inlet is opened at the upper part of the blast chamber 2, and the blast mechanism 3 blows air toward the port of the ventilation pipe 11, so that the wind passes through the blast chamber 2 downward from the air inlet. Since the blast chamber 2 is a structure that is wide at the top and narrow at the bottom, the cross-section is narrowed when the wind passes through the lower end of the blast chamber 2, and the wind speed is accelerated. When the cross-section expands after passing through the port, a negative pressure is generated outside the blast chamber 2 at this time, and the outside air is sucked in through the bucket-shaped portion 12, thereby improving the cooling efficiency of the ventilation pipe 11. Since the second end of the heat conduction plate 4 is inserted into the blast chamber 2, the wind flow in the blast chamber 2 directly takes away part of the heat transferred on the heat conduction plate 4. At the same time, the outside air will pass through the through holes of the heat conduction plate 4 when passing through the bucket-shaped portion 12, thereby accelerating the heat exchange speed of the heat conduction plate 4.

[0036] As another embodiment further provided by the present invention, a gear 9 driven by a motor is rotatably provided inside the cylinder wall 1, and an auger 7 is rotatably sleeved on the outer wall of the ventilation pipe 11. The auger 7 is engaged with the gear 9 through a transmission tooth 71 fixed thereon for transmission.

[0037] Specifically, the gear 9 is driven by the motor to rotate, and the auger 7 is driven to rotate by meshing with the transmission tooth 71, so as to fully stir the adhesive in the cylinder. Moreover, since the scraper 8 is fixedly provided on the auger 7, the adhesive stuck on the inner wall of the cylinder can be scraped off.

[0038] Working principle: Gear 9 is driven by the motor to rotate, and the meshing transmission with the transmission tooth 71 drives the auger 7 to rotate, so as to fully stir the adhesive in the cylinder. Moreover, since the scraper 8 is fixedly provided on the auger 7, the adhesive stuck on the inner wall of the cylinder can be scraped off. When the temperature in the cylinder begins to rise, the circulation pump 5 is started, so that the condensate in the cooling circuit 13 begins to circulate in the direction of the outer wall - ventilation pipe 11 - circulation pump 5 - outer wall. After the condensate moving along the ventilation pipe 11 absorbs heat, due to the setting of the heat conducting plate 4, the heat in the cooling circuit 13 is transferred to one end of the heat conducting plate 4 and is transferred to the outside through the other end of the heat conducting plate 4, and is mixed with the external air. The air is heat exchanged, and at this time the blowing mechanism 3 blows air toward the port of the ventilation pipe 11, so that the wind passes through the blast chamber 2 downward from the air inlet. Since the blast chamber 2 is a structure that is wide at the top and narrow at the bottom, the cross-section is narrowed when the wind passes through the lower end of the blast chamber 2, and the wind speed is accelerated. When the cross-section expands after passing through the port, a negative pressure is generated outside the blast chamber 2 and the outside air is sucked in through the bucket-shaped portion 12, thereby improving the cooling efficiency of the ventilation pipe 11. Since the second end of the heat conducting plate 4 is plugged into the blast chamber 2, the wind flow in the blast chamber 2 directly takes away part of the heat transferred from the heat conducting plate 4. At the same time, the outside air passes through the through holes of the heat conducting plate 4 when passing through the bucket-shaped portion 12, thereby accelerating the heat exchange speed of the heat conducting plate 4 and playing a cooling role.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
