Description

Technical Field

[0001] This utility model relates to the field of fire-retardant coating processing technology, specifically to a drying device for fire-retardant coating processing. Background Technology

[0002] Fire-retardant coatings are special coatings applied to the surface of combustible substrates to reduce the flammability of the coated material, inhibit the rapid spread of fire, and improve the fire resistance limit of the coated material. They are also known as flame-retardant coatings or fire-resistant coatings.

[0003] For example, a drying device for fire-retardant coating processing, with announcement number "CN221611743U", uses a sealing cover to seal the top of the inner chamber, preventing dust from flying and spreading during the drying process. It also incorporates a suction component to collect the flying fire-retardant powder during discharge, avoiding waste. This makes the drying device convenient. However, after the dust is sucked into the collection box, removing it still causes dust to fly again, resulting in secondary pollution. Furthermore, the sealing cover is bolted to the drying chamber, making disassembly cumbersome. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the above-mentioned equipment, which causes dust to fly and cause secondary pollution when the dust is taken out of the collection box after being sucked into the collection box, and the above-mentioned equipment is troublesome to disassemble because the sealing cover is connected to the drying box by bolts. Therefore, a drying equipment for fireproof coating processing is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a drying device for processing fire-retardant coatings, including a base plate, a box body fixedly connected to the upper end of the base plate, a feeding mechanism provided below the box body, a heating sleeve installed on the inner wall of the box body, the inner wall of the heating sleeve fitting against the outer wall of the cylinder body, a cover installed on the upper end of the box body, a motor installed on the upper end of the outer wall of the cover by bolts, and a stirring rod fixedly connected to the output shaft of the motor.

[0007] Preferably, a positioning mechanism is provided below the lid, and the upper end of the outer wall of the stirring rod is rotatably connected to the lid through a bearing.

[0008] Preferably, the feeding mechanism includes a multi-stage electric telescopic rod, the output end of which is fixedly connected to a cover plate, the inner wall of which is fixedly connected to a corrugated pipe, the corrugated pipe being fixedly connected to the discharge pipe of the cylinder, and the outer wall of which is fixedly connected to a slider.

[0009] Preferably, the outer wall of the slider is slidably connected to the groove machined on the housing, and the upper end of the outer wall of the multi-stage electric telescopic rod is fixedly connected to the housing.

[0010] Preferably, the positioning mechanism includes a magnetic plate, the outer wall of which is magnetically connected to a mounting plate, the inner wall of which is fixedly connected to a housing, the inner wall of which is machined with a first insertion hole and a second insertion hole, and an insertion block fixedly connected to the outer wall of the magnetic plate.

[0011] Preferably, the outer wall of the insert block is slidably connected to the second insertion hole and the inner wall through hole of the insert plate, and the outer wall of the insert plate is inserted into the first insertion hole.

[0012] Preferably, a cover is fixedly connected to the upper end of the insert plate, and the outer surface of the cover fits against the mounting plate.

[0013] The present invention discloses a drying device for processing fire-retardant coatings. Its advantages are as follows: Through the cooperation of the feeding mechanism and the housing, the operator places the collection bucket under the cover plate. Then, the PLC controller activates two multi-stage electric telescopic rods, which are programmed to start synchronously. The output ends of the multi-stage electric telescopic rods extend, causing the cover plate to move downwards. The downward movement of the cover plate causes the slider to move downwards. The slider is limited by the groove machined on the lower support leg of the housing, resulting in linear movement of the cover plate. The movement of the cover plate stretches the corrugated pipe, which can extend until the cover plate completely covers the collection bucket. At this point, the multi-stage electric telescopic rods stop, and the solenoid valve of the cylinder's discharge pipe is opened, allowing the dried material inside to be discharged and enter the collection bucket. Because the cover plate creates a sealed space around the collection bucket, dust dispersion is greatly reduced. Covering the collection bucket with the cover plate achieves dust suppression, reducing secondary pollution.

[0014] With the cooperation of the fixing mechanism and the cover, the workers pulled the two magnetic plates outward in sequence. The movement of the magnetic plates caused the plug to move outward, disengaging from the plug plate and the second socket. The plug was limited by the second socket and moved linearly. After the plug was disengaged, it released the limitation on the plug plate, allowing it to move vertically. Then, the workers used the handle on the cover and tools such as a crane to lift the cover upward, completing the disassembly. Compared with using bolts, disassembly can be completed simply by pulling the plug, which is faster and does not require the use of tools. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] See attached document Figure 1-6 :

[0024] In this embodiment, a drying device for processing fireproof coating includes a base plate 1, a box 2 fixedly connected to the upper end of the base plate 1, a feeding mechanism 5 provided below the box 2, a heating sleeve 3 installed on the inner wall of the box 2, the inner wall of the heating sleeve 3 being in contact with the outer wall of the cylinder 4, the heating sleeve 3 being connected to an external motor and provided with a temperature controller, and the temperature being controlled by a PLC controller.

[0025] A cover 6 is installed on the upper end of the box 2. A motor 7 is installed on the upper end of the outer wall of the cover 6 by bolts. The output shaft of the motor 7 is fixedly connected to the stirring rod 8. The rotation of the output shaft of the motor 7 drives the stirring rod 8 to rotate. The outer wall of the stirring rod 8 fits against the inner wall of the cylinder 4. A positioning mechanism 9 is provided below the cover 6. The upper end of the outer wall of the stirring rod 8 is rotatably connected to the cover 6 by a bearing.

[0026] See attached document Figure 1-2 :

[0027] The feeding mechanism 5 includes a multi-stage electric telescopic rod 501. The output end of the multi-stage electric telescopic rod 501 is fixedly connected to a cover plate 502. The extension and retraction of the output end of the multi-stage electric telescopic rod 501 drives the cover plate 502 to move. The inner wall of the cover plate 502 is fixedly connected to a corrugated pipe 504. The cover plate 502 drives the corrugated pipe 504 to extend and retract. The corrugated pipe 504 is fixedly connected to the discharge pipe of the cylinder 4.

[0028] The discharge pipe is equipped with a solenoid valve, and a slider 503 is fixedly connected to the outer wall of the cover plate 502. The cover plate 502 is limited by the slider 503 to move linearly. The outer wall of the slider 503 is slidably connected to the groove processed on the box 2. The slider 503 is slidably connected to the groove on the box 2. The upper end of the outer wall of the multi-stage electric telescopic rod 501 is fixedly connected to the box 2.

[0029] See attached document Figure 1-6 :

The mounting plate 902 is made of steel. The inner wall of the mounting plate 902 is fixedly connected to the housing 2.

The outer wall of the plug 906 is slidably connected to the second plug hole 905 and the inner wall through hole of the plug plate 903. After the plug 906 is inserted into the plug plate 903, it can limit the plug plate 903 so that it cannot move upward. The outer wall of the plug plate 903 is inserted into the first plug hole 904. The plug plate 903 is limited by the first plug hole 904 and cannot move laterally. A cover 6 is fixedly connected to the upper end of the plug plate 903. The outer surface of the cover 6 is in contact with the mounting plate 902.

[0032] Working principle:

[0033] During the drying process of fire-retardant coatings.

[0034] Work process:

[0035] Workers use a conveying mechanism to feed the fire-retardant coating into the cylinder 4 through the inlet on the cover 6. After that, the valve of the inlet is closed. Then, workers control the start of the motor 7 via PLC. The output shaft of the motor 7 rotates, which drives the stirring rod 8 to rotate. At the same time, the heating jacket 3 is started by the PLC controller, which heats it up. The heating jacket 3 is equipped with a temperature controller to keep the temperature constant. The heating jacket 3 heats the cylinder 4, which is an iron barrel with good thermal conductivity, so it can heat the fire-retardant coating inside. As the stirring rod 8 rotates, the fire-retardant coating inside moves and can be heated evenly. After heating is completed, the heating jacket 3 is stopped. The cover 6 is equipped with an exhaust hole to remove moisture.

[0036] The staff places the collection bucket under the cover plate 502, and then starts two multi-stage electric telescopic rods 501 through the PLC controller. Through programming control, they start synchronously. The output end of the multi-stage electric telescopic rods 501 extends and drives the cover plate 502 to move downward. The downward movement of the cover plate 502 drives the slider 503 to move downward. The slider 503 is limited by the sliding groove processed by the support leg at the lower end of the box 2, thus the cover plate 502 moves linearly. The movement of the cover plate 502 stretches the corrugated pipe 504. The corrugated pipe 504 can be extended until the cover plate 502 covers the collection bucket. Then the multi-stage electric telescopic rods stop, the solenoid valve of the discharge pipe of the cylinder 4 is opened, and the dried material inside is discharged and enters the collection bucket. Since the cover plate 502 covers the collection bucket, it can form a sealed space, which can greatly reduce dust flying.

[0037] Disassembly process:

[0038] The workers pulled the two magnetic plates 901 outwards in turn. The movement of the magnetic plates 901 caused the insert block 906 to move outwards, disengaging it from the insert plate 903 and the second insertion hole 905. The insert block 906 was limited by the second insertion hole 905 and moved linearly. After the insert block 906 disengaged, it released the limitation on the insert plate 903, allowing it to move vertically. Then, the workers used the handle on the cover 6 and tools such as a crane to lift the cover 6 upwards. The upward movement of the cover 6 caused the insert plate 903 to disengage from the first insertion hole 904. The insert plate 903 was limited by the first insertion hole 904 and moved linearly. The upward movement of the cover 6 caused the motor 7 and the stirring rod 8 to disengage from the cylinder 4. After that, the workers could clean the inside and the stirring rod 8.

[0039] Installation process:

[0040] The worker inserts the insert plate 903 on the cover 7 into the first socket 904. The first socket 903 limits the differential 902, thus limiting the cover 7 and preventing it from moving horizontally or rotating. Then, the worker inserts the insert blocks 906 on the two magnetic plates 901 into the second socket 905. The first socket 903 also positions the insert plate 903, making its through hole coincide with the second socket 905. The insert blocks 906 pass through the insert plate 903 and the second socket 906 to limit the vertical direction of the insert plate 903. The magnetic plates 901 can be attracted to the mounting plate 902 (the mounting plate 902 is made of steel and can be attracted by magnets), which can prevent the magnetic plates 901 from falling off due to vibration during processing, thus completing the fixation.

[0041] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
