Description

Technical Field

[0001] The invention relates to the technical field of glass wool production, and in particular to a glass wool outlet rapid cooling device. Background Art

[0002] After the glass wool undergoes the heating and curing process during the production process, the heat inside the glass wool is not easy to dissipate in a short period of time due to the thermal insulation effect of the glass wool. If the subsequent cutting and packaging processes are carried out directly, it is easy to cause a temperature difference between the temperature of the glass wool inside and the outside temperature, causing water vapor to adhere to the glass wool.

[0003] For example, the Chinese patent application number 2014102963386 discloses "A device for rapidly cooling ultra-fine glass wool at the exit of a production line". When ultra-fine glass wool is exiting the production line, it is forced to cool by the cooling conveyor (cold air is sucked in from the top) to achieve the purpose of rapidly cooling the glass wool.

[0004] For example, the Chinese patent application number 2020208212998 discloses a "new cooling device for a glass wool production line", which accelerates the flow rate of air through a ventilation fan to quickly discharge the hot air in the glass wool to achieve rapid cooling. At the same time, the humidity sensor can detect the humidity in the air and cooperate with the desiccant in the drying box to dry the air.

[0005] However, in the comparative patent "A device for rapidly cooling ultra-fine glass wool at the exit of a production line", because the cold air is sucked in from the top, the thickness of the glass wool is generally thicker, and the air suction point is located below the conveyor belt, the air actually sucked in at this time is the air below the glass wool and located at the conveyor bag, and the actual air volume passing through the glass wool is small, resulting in poor heat dissipation. In the comparative patent "A cooling device for a new type of glass wool production line", when the fan is used to accelerate the flow of air for heat dissipation, the heat dissipation effect inside the glass wool is also poor due to the thickness of the glass wool. Summary of the invention

[0006] The object of the present invention is to provide a glass wool outlet rapid cooling device, which has the function of improving the heat dissipation effect on the glass wool.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a glass wool outlet rapid cooling device, comprising a frame, a transmission chain belt arranged on the frame, a first negative pressure shell located above the middle of the transmission chain belt and having an open top is arranged in the middle of the frame, a second negative pressure shell located above the first negative pressure shell and having an open bottom is arranged in the middle of the frame for lifting and adjusting, a first arc-shaped water inlet pipe and a first arc-shaped water outlet pipe protruding upward are respectively arranged on both sides of the first negative pressure shell, a plurality of first cooling water pipes are rotatably connected between the first arc-shaped water inlet pipe and the first arc-shaped water outlet pipe through a rotating joint, and two sides of the second negative pressure shell are respectively provided with a plurality of first cooling water pipes, A plurality of second arc-shaped water inlet pipes and second arc-shaped water outlet pipes protruding downward are separately provided, and a plurality of second cooling water pipes are rotatably connected between the second arc-shaped water inlet pipe and the second arc-shaped water outlet pipe via a rotating joint. Negative pressure outlets are provided on the front and rear sides of the first negative pressure shell, and the negative pressure exhaust mechanism is also included that is connected to the two negative pressure outlets and extracts the air in the first negative pressure shell. An air inlet fan for supplying air to the first negative pressure shell is provided on the top of the second negative pressure shell. When the glass wool passes between the first negative pressure shell and the second negative pressure shell during transportation along the transmission chain belt, the lower surface of the glass wool conflicts with the plurality of first cooling water pipes and the upper surface conflicts with the plurality of second cooling water pipes.

[0008] By adopting the above technical scheme, when in use, the height of the second negative pressure shell is first lowered so that the multiple second cooling water pipes are in contact with the upper surface of the glass wool. At this time, the upper and lower surfaces of the glass wool are in contact between the multiple second cooling water pipes and the multiple first cooling water pipes, and the multiple first cooling water pipes and the second cooling water pipes can rotate with the movement of the glass wool to achieve efficient water-cooling; and the wind flows along the air inlet fan, the second negative pressure shell, the glass wool, the first negative pressure shell, and the negative pressure exhaust mechanism. At this time, the glass wool located between the first negative pressure shell and the second negative pressure shell is equivalent to the filter cotton in the filter structure, which has little effect on the wind flow, and can achieve efficient air-cooling. The glass wool is bent upward in an arc shape in this part, which can increase the windward area and improve the heat dissipation effect; in addition, there is rolling friction between the upper and lower surfaces of the glass wool and the multiple second cooling water pipes and the multiple first cooling water pipes, so that the friction force when the glass wool passes by will not be too slow, so as to avoid affecting the movement of the glass wool; ultimately, it has the effect of improving the heat dissipation effect on the glass wool and achieving rapid cooling.

[0009] The present invention is further configured as follows: a first adjustment plate that can be slidably disposed at both ends of a plurality of the first cooling water pipes to achieve contact with the side surface of the glass wool, a first adjustment mechanism that can be used to adjust the position of the first adjustment plate is disposed between the first adjustment plate and the first negative pressure shell, and a first flexible sealing sheet is disposed between the bottom of the first adjustment plate and the opening of the first negative pressure shell; a second adjustment plate that can be slidably disposed at both ends of a plurality of the second cooling water pipes to achieve contact with the side surface of the glass wool, a second adjustment mechanism that can be used to adjust the position of the second adjustment plate is disposed between the second adjustment plate and the second negative pressure shell, and a second flexible sealing sheet is disposed between the top of the second adjustment plate and the opening of the second negative pressure shell.

[0010] By adopting the above technical scheme, since the width of the generated glass wool may vary, the first adjusting mechanism makes the first adjusting plate close to or in contact with the side of the glass wool, and the second adjusting mechanism makes the second adjusting plate close to or in contact with the side of the glass surface, and cooperates with the sealing of the first flexible sealing sheet and the second flexible sealing sheet, the sealing between the opening edge of the first negative pressure shell, the opening edge of the second negative pressure shell and the glass wool can be improved, so that the air can flow as much as possible along the air inlet fan, the second negative pressure shell, the glass wool, the first negative pressure shell, and the negative pressure exhaust mechanism to ensure the air-cooling heat dissipation effect of the glass wool.

[0011] The present invention is further configured as follows: the first adjusting mechanism includes a plurality of first guide tubes arranged on the first adjusting plate, a plurality of first guide shafts arranged on the first negative pressure shell and telescopically arranged in the first guide tubes, and a first adjusting screw with a middle portion threadedly connected to the first negative pressure shell and one end rotatably connected to the first adjusting plate; the second adjusting mechanism includes a plurality of second guide tubes arranged on the second adjusting plate, a plurality of second guide shafts arranged on the second negative pressure shell and telescopically arranged in the second guide tubes, and a second adjusting screw with a middle portion threadedly connected to the second negative pressure shell and one end rotatably connected to the second adjusting plate.

[0012] By adopting the above technical solution, the operation of the first adjustment plate can be limited by the first guide tube and the first guide shaft, and the position of the first adjustment plate can be adjusted by the first adjusting screw so that the first adjustment plate can contact the side of the glass wool; similarly, the second adjustment plate can also contact the side of the glass wool.

[0013] The present invention is further configured as follows: a filter screen is provided at the negative pressure outlet to filter the fluff dropped from the glass wool, and cleaning mechanisms are provided between the two ends of the first cooling water pipe in the middle and the first negative pressure shell to clean the fluff attached to the filter screen.

[0014] By adopting the above technical solution, as the air in the first negative pressure shell is drawn out by the negative pressure exhaust mechanism, some fluff on the glass wool may be taken away together. The setting of the filter net can filter the fluff, reduce the risk of glass wool being inhaled by people after being blown into the air, and reduce the pollution to the environment; however, the fluff will gather more and more on the filter net, causing the filter net to be blocked; at this time, the fluff on the filter net can be cleaned by the cleaning mechanism to ensure the ventilation effect at the filter net.

[0015] The present invention is further configured as follows: the cleaning mechanism includes an eccentric pulley arranged at the end of the first cooling water pipe, a rotating arm rotatably connected to the inside of the first negative pressure shell, a driven pulley rotatably arranged in the middle of the rotating arm, a transmission belt arranged between the eccentric pulley and the driven pulley, and a brush arranged on the rotating arm; the rotation range of the brush on the rotating arm covers the range of the filter screen and realizes the cleaning of hair fluff; the hinge point of the rotating arm and the first negative pressure shell is located on one side of the filter screen and the height is in the middle of the height of the filter screen; the first flexible sealing sheet is provided with a notch corresponding to the cleaning mechanism that does not affect the operation of the cleaning mechanism.

[0016] The present invention is further configured as follows: the rotating arm is provided with a sliding seat slidably arranged along the length direction thereof, the sliding seat is threadedly connected with a locking bolt pressed against the rotating arm, and the driven pulley is rotatably connected to the sliding seat.

[0017] By adopting the above technical scheme, as the exhaust air in the first negative pressure shell is drawn out by the negative pressure exhaust mechanism, the friction between the glass wool and the multiple first cooling water pipes below is relatively large during operation, and the arc-shaped arrangement of the glass wool makes the force between the glass wool and the first cooling water pipe in the middle relatively large, resulting in relatively large friction. At this time, the operation of the cleaning mechanism is driven by the first cooling water pipe in the middle, so as to ensure that the first cooling water pipe can be rotated by friction as much as possible. Even if it does not rotate, the first cooling water pipe can be manually driven to rotate regularly; when the first cooling water pipe rotates, the eccentric pulley is driven to rotate, thereby driving the driven pulley to swing up and down through the transmission belt, so as to drive the rotating arm and the brush to swing back and forth, so as to remove the fluff attached to the filter net and ensure the ventilation effect at the filter net; at the same time, after the sliding seat is adjusted to the position, the placement range of the rotating arm can be adjusted to ensure that the range of the filter net is covered.

[0018] The present invention is further configured as follows: the negative pressure exhaust mechanism includes an induced draft fan, a three-way pipe connected to the air inlet end of the induced draft fan, two negative pressure pipes whose one ends are connected to the three-way pipe and the other ends are respectively connected to the negative pressure outlets, and a dust removal bag connected to the air outlet end of the induced draft fan.

[0019] By adopting the above technical solution, when the induced draft fan is working, the air in the first negative pressure shell flows along the negative pressure pipe, the induced draft fan, and the dust removal bag, and some impurities such as lint carried in the air can be filtered out by the dust removal bag.

[0020] The present invention is further configured as follows: a mounting frame is provided in the middle of the frame, brackets are provided on both sides of the mounting frame, a plurality of limiting shafts passing through the brackets are provided at the bottom of the first negative pressure shell, a compression spring is sleeved on the limiting shaft with both ends pressed against the bracket and the bottom of the first negative pressure shell, one end of the limiting shaft passing through the bracket is threadedly connected with an anti-slip nut, and two lifting cylinders are provided between the top of the second negative pressure shell and the mounting frame.

[0021] By adopting the above technical solution, a limiting shaft passing through the bracket is provided at the bottom of the first negative pressure shell, and a compression spring is sleeved on the limiting shaft with both ends pressed between the bracket and the bottom of the first negative pressure shell. Therefore, the first negative pressure shell has a good shock absorbing effect during use.

[0022] The present invention is further configured as follows: arcuate transition plates extending toward the transmission chain are symmetrically arranged at the openings at both ends of the first negative pressure shell, and the end of the arcuate transition plate away from the first negative pressure shell is in a U-shape extending toward the first negative pressure shell.

[0023] By adopting the above technical solution, the setting of the arc filter plate can support the glass wool between the transmission chain belt and multiple first cooling water pipes, and the end of the arc transition plate away from the first negative pressure shell is in a U-shape extending toward the first negative pressure shell, thereby avoiding damage to the glass wool.

[0036] like Figure 1 As shown, the negative pressure exhaust mechanism 7 includes an induced draft fan 71, a three-way pipe 72 connected to the air inlet end of the induced draft fan 71, two negative pressure pipes 73 with one end connected to the three-way pipe 72 and the other end respectively connected to the negative pressure outlet 31, and a dust removal bag 74 connected to the air outlet end of the induced draft fan 71.

[0037] like Figure 4 and Figure 5As shown, a filter screen 32 for filtering fluff dropped from the glass wool is provided at the negative pressure outlet 31, and a cleaning mechanism 9 for cleaning fluff attached to the filter screen 32 is provided between the two ends of the first cooling water pipe 53 located in the middle and the first negative pressure housing 3. The cleaning mechanism 9 includes an eccentric pulley 91 provided at the end of the first cooling water pipe 53, a rotating arm 92 rotatably connected to the inside of the first negative pressure housing 3, a driven pulley 93 rotatably provided in the middle of the rotating arm 92, a transmission belt 94 provided between the eccentric pulley 91 and the driven pulley 93, and a brush 95 provided on the rotating arm 92. The rotation range of the brush 95 on the rotating arm 92 covers the range where the filter screen 32 is located and the fluff is cleaned. The hinge point of the rotating arm 92 and the first negative pressure housing 3 is located on one side of the filter screen 32 and the height is in the middle of the height of the filter screen 32. The first flexible sealing sheet 56 is provided with a notch (not marked in the figure) corresponding to the cleaning mechanism 9 that does not affect the operation of the cleaning mechanism 9. At the same time, the rotating arm 92 is provided with a sliding seat 96 which is slidably arranged along the length direction thereof, the sliding seat 96 is threadedly connected with a locking bolt 97 which is pressed against the rotating arm 92, and the driven pulley 93 is rotatably connected to the sliding seat 96. At the same time, after the sliding seat 96 is adjusted in position, the placement range of the rotating arm 92 can be adjusted to ensure that the range where the filter screen 32 is located is covered.

[0038] Implementation effect: When in use, first lower the height of the second negative pressure shell 4 so that the multiple second cooling water pipes 63 are in contact with the upper surface of the glass wool. At this time, the upper and lower surfaces of the glass wool are in contact between the multiple second cooling water pipes 63 and the multiple first cooling water pipes 53, and the multiple first cooling water pipes 53 and the second cooling water pipes 63 can rotate with the movement of the glass wool to achieve efficient water-cooling; and the wind flows along the air inlet fan 8, the second negative pressure shell 4, the glass wool, the first negative pressure shell 3, and the negative pressure exhaust mechanism 7. At this time, the glass wool located between the first negative pressure shell 3 and the second negative pressure shell 4 is equivalent to the filter cotton in the filter structure, which has little effect on the wind flow and can achieve efficient air-cooling. The glass wool is bent upward in an arc shape in this part, which can increase the windward area and improve the heat dissipation effect; in addition, there is rolling friction between the upper and lower surfaces of the glass wool and the multiple second cooling water pipes 63 and the multiple first cooling water pipes 53, so that the friction force when the glass wool passes by will not be too slow, so as to avoid affecting the movement of the glass wool; ultimately, it has the effect of improving the heat dissipation effect on the glass wool and achieving rapid cooling.

[0039] Since the width of the generated glass wool may vary, the first adjusting mechanism 55 is used to make the first adjusting plate 54 close to or in contact with the side of the glass wool, and the second adjusting mechanism 65 is used to make the second adjusting plate 64 close to or in contact with the side of the glass surface, and cooperate with the sealing of the first flexible sealing sheet 56 and the second flexible sealing sheet 66, so as to improve the sealing between the opening edge of the first negative pressure shell 3, the opening edge of the second negative pressure shell 4 and the glass wool, so that the air can flow as much as possible along the air inlet fan 8, the second negative pressure shell 4, the glass wool, the first negative pressure shell 3, and the negative pressure exhaust mechanism 7 to ensure the air-cooling and heat dissipation effect of the glass wool.

[0040] As the air in the first negative pressure shell 3 is extracted by the negative pressure exhaust mechanism 7, the friction between the glass wool and the multiple first cooling water pipes 53 below is relatively large during operation, and the arc-shaped arrangement of the glass wool makes the force between the glass wool and the first cooling water pipe 53 in the middle relatively large, resulting in relatively large friction. At this time, the operation of the cleaning mechanism 9 is driven by the first cooling water pipe 53 in the middle, so as to ensure that the first cooling water pipe 53 can be rotated by friction as much as possible. Even if it does not rotate, the first cooling water pipe 53 can be manually driven to rotate regularly; when the first cooling water pipe 53 rotates, the eccentric pulley 91 is driven to rotate, thereby driving the driven pulley 93 to swing up and down through the transmission belt 94, so as to drive the rotating arm 92 and the brush 95 to swing back and forth, so as to remove the fluff attached to the filter screen 32 and ensure the ventilation effect at the filter screen 32.
