TECHNICAL FIELD
[0001] The utility model relates to the technical field of color coating, more specifically, the utility model relates to a kind of color coating line solidification furnace strong cooling device. BACKGROUND
[0002] In the production process of color coated sheet, the cooling operation of the strong cooling device is a key step after the solidification furnace high-temperature drying of the color coated sheet. In the prior art, the operation of the related equipment in this link mostly depends on manual start-stop, and there is a lack of effective automatic coordination and control mechanism between the equipment.
[0003] The color coated sheet dried by the solidification furnace enters the strong cooling device, and the strong cooling device sprays cooling water to both sides of the sheet strip to reduce the temperature, and a large amount of water vapor is generated in the process and needs to be treated by the exhaust equipment. However, due to the lack of interlocking mechanism, the water vapor often diffuses in the workshop, not only interfering with the production sight and affecting the operation of workers, but also possibly causing safety hazards such as electrical equipment short circuit, and at the same time, damaging the overall environment of the workshop, increasing the cleaning and maintenance cost and difficulty.
[0004] When the production line is accidentally stopped, the strong cooling water is easy to flow back to the solidification furnace which is still at high temperature along the sheet strip, and the inner shell of the furnace body shrinks sharply due to sudden cooling, causing the deformation and damage of the furnace body structure, seriously affecting the heating performance and service life of the solidification furnace, and increasing the production cost and delaying the production progress due to frequent maintenance or replacement of furnace parts.
[0005] In terms of wringer operation, due to the uncertainty of manual operation, the strong cooling device is often running while the wringer is not put into operation in time, and a large amount of strong cooling water spills out of the production line, causing water resource waste, wetting the surrounding equipment and ground, and causing secondary problems such as equipment rust and short circuit; on the contrary, after the strong cooling device stops, if the wringer does not stop in time, the wringer roller running without water will be quickly worn out, shortening the equipment replacement cycle and increasing the equipment purchase and maintenance capital investment.
[0006] In addition, if the hot air blowing equipment is not started synchronously with the strong cooling device, the residual cooling water on the surface of the sheet strip will cause the sheet strip to deviate when passing through the correction roller due to uneven friction force, which not only damages the surface coating of the sheet strip and reduces the product quality, but also interrupts the production process, reduces the production efficiency, and increases the waste rate and production cost due to frequent sheet strip deviation adjustment operation.
[0007] Therefore, the present application provides a color coating line solidification furnace strong cooling device. Utility model content

DETAILED DESCRIPTION
[0027] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.
[0028] As shown in the accompanying drawings Figures 1-4The device comprises a curing furnace 1, a quenching assembly 2, a steam exhaust device 3, a squeezing machine 1 6, a squeezing machine 2 7, a hot air blowing dryer 8 and a strip 9, the curing furnace 1 is connected with the quenching assembly 2 on one side, the quenching assembly 2 is connected with the steam exhaust device 3, the quenching assembly 2 is connected with the squeezing machine 1 6 at the tail end, the squeezing machine 1 6 is connected with the squeezing machine 2 7 on one side, the squeezing machine 2 7 is connected with the hot air blowing dryer 8 on one side, and the strip 9 is connected with a conveyor in sequence through the curing furnace 1, the quenching assembly 2, the squeezing machine 1 6, the squeezing machine 2 7 and the hot air blowing dryer 8.
[0029] The switch of the quenching assembly 2 is forcibly associated with the switch of the steam exhaust device 3, and the switch of the quenching assembly 2 is forcibly associated with the switch of the conveyor, so that the quenching assembly 2 and the steam exhaust device 3 are controlled to stop running when the strip 9 stops running.
[0030] The switch of the quenching assembly 2 is forcibly associated with the switch of the squeezing machine 1 6 and the squeezing machine 2 7, so that the squeezing machine 1 6 and the squeezing machine 2 7 are controlled to stop running when the quenching assembly 2 stops running.
[0031] The switch of the squeezing machine 1 6 and the squeezing machine 2 7 is forcibly associated with the switch of the hot air blowing dryer 8, so that the hot air blowing dryer 8 is controlled to stop running when the squeezing machine 1 6 and the squeezing machine 2 7 stop running.
[0032] In specific implementation, after the color coated plate is dried by high temperature in the curing furnace 1, the color coated plate enters the quenching assembly 2 for cooling, the quenching assembly 2 sprays cooling water to the front and back of the strip 9 to cool the strip 9, in the cooling process, when the cooling water is sprayed to the surface of the high temperature strip 9, a large amount of steam is generated due to the sudden increase of water temperature, the steam is collected and discharged from the workshop by the steam exhaust device 3, so as to prevent the steam from spreading in the workshop and affecting the workshop environment, the cooled strip 9 is extruded by the squeezing rollers of the squeezing machine 1 6 and the squeezing machine 2 7 in sequence to extrude most of the water on the surface of the strip 9, and then the residual water film on the surface of the strip 9 is blown dry by the hot air blowing dryer 8, and then the strip 9 enters the subsequent process equipment.
[0033] Secondly, when the quenching assembly 2 runs, the production line stops, the quenching assembly 2 gives a stop spraying signal, and the stop spraying is not limited to closing the valve and stopping the circulating water pump, so that when the strip 9 of the production line stops running, the quenching water can not flow back to the curing furnace 1 along the strip 9, and the curing furnace 1 is still in a high temperature state at this time, if the cooling water enters the curing furnace 1 at this time, the inner shell of the curing furnace 1 will be rapidly cooled and contracted, causing damage to the curing furnace 1, therefore, by interlocking the quenching assembly 2 with the running of the strip 9 of the production line, the curing furnace 1 can be effectively protected.
[0034] When the temperature of the curing furnace 1 is higher than 80 DEG C, the production line is started to run, the forced cooling assembly 2 is started to run, and when the temperature of the curing furnace 1 is higher than 80 DEG C, the forced cooling cannot be started due to the circulating water level alarm or other reasons such as the water pump, the running of the production line is forced to stop, and an alarm is prompted, so as to protect the curing furnace 1 and avoid production accumulation.
[0035] When the forced cooling assembly 2 is started to run, the forced cooling squeeze dryer gives an input signal and is started to run at the same time.
[0036] When the forced cooling assembly 2 is stopped to run, the rear connected squeeze dryer one 6 and the squeeze dryer two 7 are automatically disconnected after 30-180s, so as to prevent the squeeze roller from being quickly abraded when running without water.
[0037] When the forced cooling assembly 2 is started to run, the hot air blowing dryer 8 is started to run at the same time, so as to avoid the residual water on the surface of the plate strip 9 from causing the plate strip 9 to deviate at the position of the deviation correcting roller, thereby avoiding the damage of the plate strip 9 and further causing the stoppage.
[0038] When the forced cooling assembly is started to run, the steam exhaust equipment 3 is started at the same time, so as to prevent the water vapor from overflowing outside.
[0039] The plate strip 9 input and output ends at both ends of the forced cooling assembly 2 are respectively provided with the air suction port one 4 and the air suction port two 5, and the air suction port one 4 and the air suction port two 5 are connected with the steam exhaust equipment 3.
[0040] In specific implementation, when the forced cooling assembly 2 sprays and cools the plate strip 9, the steam exhaust equipment 3 is started to run, and the generated water vapor is exhausted to outside the workshop through the air suction port one 4 and the air suction port two 5, so as to prevent the water vapor from spreading in the workshop and affecting the workshop environment.
[0041] The squeeze dryer one 6 and the squeeze dryer two 7 are linked and arranged, and the plate strip 9 passes through the squeeze dryer one 6 and the squeeze dryer two 7 in sequence.
[0042] In specific implementation, after the plate strip 9 is cooled, the plate strip 9 first enters the squeeze dryer one 6 to be squeezed and dried, and then is squeezed and dried again by the squeeze dryer two 7, so as to improve the removal effect of the residual on the surface of the plate strip 9.
[0043] The squeeze dryer one 6 and the squeeze dryer two 7 are both provided with a squeeze roller connecting frame 11 for fixing the squeeze roller, and the squeeze roller connecting frame 11 is provided with an indication mark 12, and one side of each indication mark 12 is provided with a scale plate 10.
[0044] In the embodiment, the distance between the squeeze rollers can be adjusted by adjusting the lifting of the connecting frame 11 of the squeeze rollers, so that the squeeze rollers can better cooperate with the plate strip 9. When the squeeze rollers are lifted, the indicator 12 is lifted and indicates the scale plate 10 on one side, so that the height of the squeeze rollers can be accurately adjusted, and the squeezing precision between the squeeze rollers and the plate strip 9 is improved.
[0045] The hot air blowing dryer 8 is connected with a plurality of nozzles 13, and each nozzle 13 is obliquely arranged and has a V-shaped structure.
[0046] In the embodiment, the nozzles 13 are obliquely arranged and have a V-shaped structure, so that the hot air flow can blow the water on the surface of the plate strip 9 from the middle to the two edges, the blowing area is increased, the water film is blown off, and the water film is dried, so that the blowing and drying effects and efficiency are further improved.
[0047] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
