Description

Technical Field

[0001] This utility model relates to the field of formaldehyde preparation technology, and more specifically, to a drying device based on formaldehyde preparation. Background Technology

[0002] Formaldehyde, also known as methanal, is an organic compound, a colorless gas that is difficult to detect at low concentrations and is easily masked by other odors, such as those found in air fresheners. At higher concentrations, it has a strong, irritating, and suffocating odor and is irritating to the eyes and nose. Formaldehyde has a wide range of applications in the petrochemical, pharmaceutical, textile, biochemical, energy, and transportation industries. It can be used as a disinfectant and preservative, and is also used to prepare various products such as phenolic resin, urea-formaldehyde resin, melamine resin, hexamethylenetetramine, and pentaerythritol. Formaldehyde is a strong irritant to mucous membranes and has a lachrymatory effect. It can coagulate proteins and, upon contact with the skin, can cause hardening of the skin and even local tissue necrosis.

[0003] During the formaldehyde preparation process, operators often use corresponding drying equipment to dry the formaldehyde raw materials. However, in actual use, although the existing drying equipment has basic drying functions, it usually pours all the formaldehyde raw materials to be dried into the drying equipment at once. This not only reduces the efficiency of the drying operation, but also increases the load on the equipment due to the large accumulation of materials, thus reducing the service life of the equipment. Therefore, it is necessary to improve it. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 7 As shown, this utility model provides a drying device based on formaldehyde preparation, including a base plate 1, a fixing frame 2 fixedly installed on the top of the base plate 1, a hollow plate 3 fixedly connected to the left side of the top of the fixing frame 2, a first motor 4 fixedly connected to the left side of the hollow plate 3, a first rotating shaft 5 fixedly sleeved at the other end of the output shaft of the first motor 4, a first gear 6 fixedly sleeved at the other end of the first rotating shaft 5, toothed plates 7 meshing with the top and bottom of the outer surface of the first gear 6, two toothed plates 7, rectangular rods 9 fixedly connected to the right side of the two toothed plates 7 respectively, a limiting rod 8 fixedly connected to the left side of the top of the base plate 1, the outer surface of the limiting rod 8 movably sleeved with the inside of the toothed plate 7, a sealing plate 10 fixedly connected to the inner side of the rectangular rod 9, and the outer surface of the sealing plate 10 movably sleeved with the inside of the hollow plate 3.

[0025] When the first motor 4 starts running, it will cause the first rotating shaft 5 to drive the first gear 6 to rotate, and cause the two toothed plates 7 to move horizontally towards each other under the limiting action of the limiting rod 8. This will cause the two rectangular rods 9 to drive the two closed plates 10 to move towards each other together under the limiting action of the hollow plate 3. When the two closed plates 10 come into contact, they will achieve the sealing effect on the top of the inner cavity of the hollow plate 3.

[0026] The drying cylinder 17 is fixedly sleeved inside the fixed frame 2. The bottom of the drying cylinder 17 is fixedly sleeved with the discharge pipe 18. The right side of the drying cylinder 17 is fixedly connected with the second motor 11. The other end of the output shaft of the second motor 11 is fixedly sleeved with the second rotating shaft 12. The other end of the second rotating shaft 12 passes through the drying cylinder 17 and extends into the interior of the drying cylinder 17 and is fixedly connected with the stirring rod 13.

[0027] When the second motor 11 starts running, it will cause the second rotating shaft 12 to drive the stirring rod 13 to rotate.

[0028] The drying cylinder 17 has a first air duct 14 fixedly connected to its left side. A hot air blower 15 is fixedly connected to the bottom end of the first air duct 14. The hot air blower 15 is fixedly installed on the left side of the drying cylinder 17. A second air duct 16 is fixedly connected to the bottom of the hot air blower 15.

[0029] When the hot air blower 15 starts running, it will draw in the outside air through the second air duct 16, and after being heated by the hot air blower 15, it will be discharged into the interior of the drying cylinder 17 through the first air duct 14.

[0030] Among them, a connecting pipe 19 is fixedly connected to the right side of the top of the base plate 1. The bottom end of the connecting pipe 19 passes through the fixing frame 2 and the drying cylinder 17 in sequence and extends into the interior of the drying cylinder 17. A connecting frame 20 is fixedly sleeved on the right side of the connecting pipe 19. A fixing pipe 21 is fixedly sleeved on the right side of the connecting frame 20. A filter screen 27 is movably connected inside the connecting frame 20.

[0031] When hot air is discharged into the drying cylinder 17 by the hot air blower 15, the toxic air inside the drying cylinder 17 will enter the interior of the connecting frame 20 through the connecting pipe 19, and after being filtered by the filter screen 27, it will be discharged from the equipment through the fixed pipe 21.

[0032] The top of the connecting frame 20 is fitted with a handle 22, the bottom end of which passes through the connecting frame 20 and extends into the inner cavity of the connecting frame 20 and is fixedly fitted with a rotating plate 23. A connecting rod 24 is hinged to the left side of the rotating plate 23, and a movable plate 25 is hinged to the other end of the connecting rod 24. A fixed plate 26 is fixedly connected to the left side of the inner cavity of the connecting frame 20. The right side of the fixed plate 26 is movably connected to the left side of the filter screen 27. The left side of the movable plate 25 is movably connected to the right side of the filter screen 27. The outer surface of the movable plate 25 is movably connected to the interior of the connecting frame 20.

[0033] When the handle 22 is rotated, the rotating plate 23 will rotate as well, which will cause the connecting rod 24 to move. At this time, due to the limiting effect of the connecting frame 20, the movable plate 25 will move horizontally to the right along the inside of the connecting frame 20, thereby releasing the fixing effect on the filter screen 27.

[0034] The top of the connecting frame 20 is fixedly connected to a rectangular plate 28. A pull rod 29 is movably sleeved inside the rectangular plate 28. The tail end of the pull rod 29 passes through the rectangular plate 28 and extends to the outside of the rectangular plate 28 and is fixedly connected to a locking block 30. A second gear 31 is meshed with the outer surface of the locking block 30. The interior of the second gear 31 is fixedly sleeved with the outer surface of the handle 22.

[0035] When the lever 29 is pulled, the locking block 30 will move horizontally backward under the limiting action of the rectangular plate 28, thereby releasing the fixing effect on the second gear 31.

[0036] Among them, a spring 32 is movably sleeved on the outer surface of the pull rod 29. The front end of the spring 32 is fixedly connected to the back of the rectangular plate 28, and the tail end of the spring 32 is fixedly connected to the front of the locking block 30.

[0037] Due to the elastic force of the spring 32, the locking block 30 has a good reset effect during subsequent movements.

[0038] Working principle and usage process of this utility model:

[0039] First, the formaldehyde raw material to be dried is added into the inner cavity of the drying cylinder 17 through the hollow plate 3. When it is necessary to seal the hollow plate 3 to control the amount added at one time, the first motor 4 is started, and the first rotating shaft 5 drives the first gear 6 to rotate. Under the limiting action of the limiting rod 8, the two toothed plates 7 move horizontally towards each other. This causes the two rectangular rods 9 to drive the two sealing plates 10 to move towards each other together under the limiting action of the hollow plate 3. When the two sealing plates 10 come into contact, they will seal the top of the inner cavity of the hollow plate 3, thereby controlling the amount of raw material added at one time, completing the function of quantitative addition, improving the drying efficiency of the subsequent drying equipment and the service life of the equipment.

[0040] After the raw materials are added, the sealing plate 10 is kept closed to the top of the hollow plate 3, and the second motor 11 is started, causing the second rotating shaft 12 to drive the stirring rod 13 to rotate. At the same time, the hot air blower 15 is started, drawing in external air through the second air duct 16. After being heated by the hot air blower 15, the air is discharged into the drying cylinder 17 through the first air duct 14, where the drying process will begin. Toxic air will enter the connecting frame 20 through the connecting pipe 19, be filtered by the filter screen 27, and then be discharged through the fixed pipe 21. When the filter screen 27 becomes clogged during prolonged use, it needs to be replaced. When changing the filter screen, pull the lever 29, causing the locking block 30 to move horizontally backward under the limiting action of the rectangular plate 28, and disengaging the locking block 30 from the second gear 31, thereby releasing the fixing effect on the second gear 31 and the handle 22. Then, rotate the handle 22, causing the rotating plate 23 to start rotating and the connecting rod 24 to move. At this time, due to the limiting action of the connecting frame 20, the movable plate 25 will move horizontally to the right, ultimately releasing the fixing effect on the filter screen 27. This allows the operator to quickly disassemble and assemble the filter screen 27, improving the efficiency of the operator in changing the filter screen 27 and reducing the labor intensity of the operator.
