Description

Technical Field

[0001] This utility model relates to the field of sulfonated phenolic resin production technology, and in particular to a drying device for sulfonated phenolic resin production. Background Technology

[0002] Currently, most drying equipment for producing sulfonated phenolic resins on the market uses spray drying. The principle is to bring the atomized material into contact with hot air in the drying tower, where the moisture is rapidly vaporized to obtain a dried product. This method can directly dry solutions and emulsions into powder or granular products, eliminating the need for evaporation, crushing and other processes.

[0003] For example, CN209464615U discloses a drying device for producing sulfonated phenolic resin, characterized by comprising a feeding pump (1), an air heater (2), a hot air distributor (3), a high-speed centrifugal atomizer (4), and a drying tower (5). The centrifugal atomizing disc (6) of the high-speed centrifugal atomizer (4) is provided with a duckbill-shaped nozzle (9). A shut-off fan (8) is provided between the drying tower (5) and the discharge port (12). A viewing window (7) is provided in the middle of the drying tower (5). This utility model provides a drying device for producing sulfonated phenolic resin with excellent atomization effect, high efficiency, reduced material adhesion to the wall, easy observation, stable discharge, and high efficiency.

[0004] However, in the current technology, the sulfonated phenolic resin tends to stick together after drying and dehydration in traditional drying equipment, which can easily cause blockage and affect drying efficiency, thus limiting the practicality of the equipment to a certain extent. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that sulfonated phenolic resin will stick together after drying and dehydration, which will easily cause blockage and affect drying efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for the production of sulfonated phenolic resin, comprising a base plate, on both sides of the upper surface of the base plate being symmetrically fixedly arranged with support plates, each of the two sets of support plates having a rotating cavity, each of the two sets of rotating cavities having a rotating ring rotatably arranged inside, a drying cylinder being fixedly arranged between the inner cavities of the two sets of rotating rings, a heating sleeve being fixedly arranged on the outer surface of the drying cylinder between the two sets of support plates, a second motor being fixedly arranged on one side of the outer surface of the drying cylinder, a one-way exhaust pipe being fixedly arranged on the other side of the outer surface of the drying cylinder, a rotating rod being driven at the output end of the second motor, a threaded feeding pipe being driven at one side of the rotating rod, a connecting pipe being symmetrically fixedly arranged on the other side of the rotating rod, and an arc-shaped stirring blade being fixedly arranged between the two sets of connecting pipes, the arc-shaped stirring blade being in contact with the inner cavity of the drying cylinder.

[0007] In a preferred embodiment, a feed pipe is fixedly installed on the upper surface of the drying cylinder near the one-way exhaust pipe, and a first solenoid valve is installed on the surface of the feed pipe.

[0008] In a preferred embodiment, a discharge pipe is fixedly installed on the lower surface of the drying cylinder near the second motor, and a second solenoid valve is installed on the surface of the discharge pipe.

[0009] In a preferred embodiment, a first motor is fixedly mounted on the upper surface of one side of the support plate, and a first drive wheel is driven from the output end of the first motor.

[0010] In a preferred embodiment, a second drive wheel is fixedly disposed on the outer surface of the drying cylinder between the support plate and the discharge pipe, and the second drive wheel is meshed and connected to the first drive wheel for transmission.

[0011] In a preferred embodiment, both the base plate and the support plate are made of rubber.

[0012] In a preferred embodiment, a plurality of ball bearings are arranged in a ring between the rotating cavity and the rotating ring.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention utilizes the interplay between a threaded feeding pipe, a connecting pipe, and an arc-shaped stirring blade. A heating sleeve heats the drying cylinder, while the output of a second motor drives a rotating rod. This rotating rod, in turn, stirs the sulfonated phenolic resin via the connecting pipe and the arc-shaped stirring blade, pushing the resin towards one side of the threaded feeding pipe. Water vapor is discharged through a one-way exhaust pipe, and the condensed and agglomerated sulfonated phenolic resin is ground by the threaded feeding pipe and moves towards the discharge pipe, effectively preventing material blockage and improving the device's practicality and drying efficiency.

[0015] This invention achieves dual stirring and drying by setting up a first motor, a first drive wheel, and a second drive wheel in coordination. During material stirring and drying, the output of the first motor drives the first drive wheel to rotate, and the first drive wheel drives the drying cylinder to rotate through the second drive wheel. The drying cylinder drives the rotating ring to rotate along the rotating cavity, thereby achieving the purpose of dual stirring and drying, and further improving the practicality and drying efficiency of the device.

[0023] Please see Figure 1-4This utility model provides a technical solution: a drying device for the production of sulfonated phenolic resin, including a base plate 1, with support plates 2 symmetrically fixed on both sides of the upper surface of the base plate 1.

A drying cylinder 7 is fixedly arranged between the inner cavities of the two sets of rotating rings 6. A heating sleeve 8 is fixedly arranged on the outer surface of the drying cylinder 7 between the two sets of support plates 2. A second motor 15 is fixedly arranged on one side of the outer surface of the drying cylinder 7, and a one-way exhaust pipe 10 is fixedly arranged on the other side of the outer surface of the drying cylinder 7. A rotating rod 16 is driven at the output end of the second motor 15, and a rotating rod 16 is driven on one side of its surface. A threaded feeding pipe 17 is provided, and a connecting pipe 18 is symmetrically fixed on the other side of the rotating rod 16.

The heating sleeve 8 heats the drying cylinder 7, and the output end of the second motor 15 drives the rotating rod 16 to rotate. The rotating rod 16 drives the connecting pipe 18 and the arc-shaped stirring blade 19 to stir the sulfonated phenolic resin and push the sulfonated phenolic resin to one side of the threaded feeding pipe 17. Water vapor is discharged to the outside through the one-way exhaust pipe 10. The condensed and agglomerated sulfonated phenolic resin will move to the discharge pipe 13 through the grinding of the threaded feeding pipe 17, effectively avoiding material blockage.

[0024] like Figure 1-4 As shown, a feed pipe 11 is fixedly installed on the upper surface of the drying cylinder 7 near the one-way exhaust pipe 10. A first solenoid valve 12 is installed on the surface of the feed pipe 11. A discharge pipe 13 is fixedly installed on the lower surface of the drying cylinder 7 near the second motor 15. A second solenoid valve 14 is installed on the surface of the discharge pipe 13.

The drying cylinder 7 drives the rotating ring 6 to rotate along the rotating cavity 3 to achieve the purpose of double stirring and drying, which further enhances the drying efficiency.

[0026] like Figure 1-4 As shown, the surfaces of both the base plate 1 and the support plate 2 are made of rubber. The application of rubber material provides a certain degree of shock absorption for the equipment.

The heating sleeve 8 heats the drying cylinder 7, while the output end of the second motor 15 drives the rotating rod 16 to rotate. The rotating rod 16 drives the connecting pipe 18 and the arc-shaped stirring blade 19 to stir the sulfonated phenolic resin and push it to one side of the threaded feed pipe 17. Water vapor is discharged to the outside through the one-way exhaust pipe 10. The condensed and agglomerated sulfonated phenolic resin will move to the discharge pipe 13 through the grinding of the threaded feed pipe 17. The output end of the first motor 4 drives the first drive wheel 5 to rotate, and the first drive wheel 5 drives the drying cylinder 7 to rotate through the second drive wheel 9.
