Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to an energy-saving drying device for SBS bromide. Background Technology

[0002] Brominated SBS is a new type of environmentally friendly polymer flame retardant, mainly used in exterior wall insulation materials such as EPS and XPS boards. It is an excellent alternative to the discontinued flame retardant hexabromocyclododecane (HBCD). During the production of brominated SBS, due to its very low softening point, fluidized bed drying can only be carried out using low-temperature hot air. Materials with high moisture content require a longer drying time, resulting in high average energy consumption.

[0003] A prior art patent with publication number CN221444753U discloses a solution comprising a main structure, a conveying mechanism, and an auxiliary mechanism. The conveying mechanism is located in the middle of the main structure, and the auxiliary mechanism is located at the front end of the main structure. The main structure includes an insulation box A, a boiler, an insulation box B, and a steam pipe. The boiler is fixedly installed at the left end of the insulation box A. This low-temperature energy-saving drying device for SBS bromide, through the installation of the main structure, enables the dryer A to easily reduce the moisture content of the material. The heating chamber is connected to the steam pipe, allowing the moisture in the material inside the dryer A to evaporate rapidly. The hot water delivery pipe transports hot water to the dryer B, enabling the material inside to undergo deep drying to a specified degree of dryness. The circulation pipe facilitates the transportation of hot water from the boiler to the dryer B for circulation, serving as a heat source and reducing energy consumption, thus improving the energy efficiency of the low-temperature energy-saving drying device for SBS bromide.

[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0005] First, existing heat exchange media cannot fully utilize the heat of the heat exchange media when drying brominated SBS, thus reducing the drying efficiency of the heat exchange media for brominated SBS.

[0006] Secondly, when existing equipment dries the liquid inside brominated SBS, the dried water vapor tends to accumulate at the top of the tank, making it easy for it to mix with the brominated SBS again, thus reducing the drying efficiency of the brominated SBS.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides an energy-saving drying device for brominated SBS. This device solves the problems of traditional technologies where the heat exchange medium cannot fully utilize its heat during the drying of brominated SBS, thus reducing the drying efficiency; and the existing devices where, during the drying of the liquid within the brominated SBS, the dried water vapor tends to accumulate at the top of the tank, making it easy for the vapor to re-mix with the brominated SBS, further reducing the drying efficiency.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An energy-saving drying device for SBS bromide includes a drying tank. A media transfer column is vertically rotatable within the drying tank. Several baffles are fixedly connected side-by-side from top to bottom on opposite side walls of the media transfer column. Each baffle has an S-shaped heat exchange channel. A connecting channel linking two adjacent heat exchange channels is formed in the area between the vertically adjacent baffles. A media inlet channel, connected to the lowermost connecting channel, is located at the lower end of the media transfer column. A media outlet channel, connected to the uppermost connecting channel, is located at the upper end of the media transfer column.

[0011] The outer wall of the drying tank is provided with a heat exchange jacket, and a heat exchange interlayer is formed between the inner wall of the heat exchange jacket and the outer wall of the drying tank. The medium discharge channel is connected to the heat exchange interlayer through a connecting pipe assembly.

[0012] As an optimized solution, the top of the drying tank is fixedly connected to a steam discharge chamber shell arranged in a ring, and the top surface of the drying tank is evenly distributed with a number of steam outlet holes that communicate with the steam discharge chamber shell.

[0013] As an optimized solution, a suction cylinder communicating with the inner cavity is fixedly connected to the top of the steam discharge chamber shell.

[0014] As an optimized solution, the drying tank has several heat exchange plates fixed from top to bottom on the outer wall of the heat exchange jacket.

[0015] As an optimized solution, the lower edge of the bottommost spoiler makes frictional contact with the inner bottom surface of the drying tank.

[0016] As an optimized solution, the outer ends of the spoilers are fixedly connected to vertically arranged side spoilers.

[0017] As an optimized solution, the sidewall of the side spoiler makes frictional contact with the inner wall of the drying tank.

[0018] As an optimized solution, the connecting pipe assembly includes a connecting elbow that is rotatably inserted into the medium discharge channel, and the outlet end of the connecting elbow is connected to the heat exchange jacket via a pipe.

[0019] As an optimized solution, an inlet cylinder and an outlet cylinder that communicate with the heat exchange jacket are fixedly connected to the outer wall of the heat exchange jacket, and the inlet cylinder is connected to the pipeline.

[0020] As an optimized solution, the inlet cylinder is located near the lower end of the heat exchange jacket, and the outlet cylinder is located near the upper end of the heat exchange jacket.

[0021] As an optimized solution, a toothed ring is fixedly connected to the outer wall of the medium transmission column below the drying tank, and a drive motor is fixedly connected to the outer bottom surface of the drying tank. The output shaft of the drive motor meshes with the toothed ring through a gear.

[0022] As an optimized solution, a feed cylinder communicating with the inner cavity is fixedly connected to the top of the drying tank.

[0023] As an optimized solution, a discharge cylinder communicating with the inner cavity is fixedly connected to the bottom of the tank.

[0024] As an optimized solution, a medium inlet cylinder is rotatably inserted into the lower port of the medium inlet channel.

[0025] As an optimized solution, an air inlet valve communicating with the inner cavity is fixedly connected to the outer wall of the drying tank near the top.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] The medium enters the cylinder and connects to the heat exchange medium. The heat exchange medium enters into several baffles through the medium inlet channel and finally enters the heat exchange jacket through the medium outlet channel under the action of the connecting pipe group. The heat exchange jacket then exchanges heat with the outside of the drying tank, which greatly improves the heat exchange capacity of the heat exchange medium and improves the drying efficiency of brominated SBS in the drying tank.

[0028] By setting a steam discharge chamber shell at the top of the drying tank, and connecting the steam discharge chamber shell to a suction cylinder, the water vapor inside the drying tank can be discharged in a timely manner through the steam outlet, preventing the water vapor from coming into contact with the brominated SBS inside again, thus improving the drying efficiency.

[0029] The bottom edge of the lowest baffle makes frictional contact with the inner bottom surface of the drying tank, while the side walls of the side baffles make frictional contact with the inner wall of the drying tank. This improves the uniformity of drying and ensures the thorough discharge of materials. Attached Figure Description

A media inlet channel 7, connected to the lowermost connecting channel 6, is provided at the lower end of the media transfer column 2. A media outlet channel 11, connected to the uppermost connecting channel 6, is provided at the upper end of the media transfer column 2.

[0035] A heat exchange jacket 14 is provided on the outer wall of the drying tank 1, and a heat exchange jacket 15 is formed between the inner wall of the heat exchange jacket 14 and the outer wall of the drying tank 1.

[0036] The top of the drying tank 1 is fixed with a steam discharge chamber shell 19 arranged in a ring shape, and the top surface of the drying tank 1 is evenly distributed with a number of steam outlet holes 20 that communicate with the steam discharge chamber shell 19.

[0037] A suction cylinder 22, which communicates with the inner cavity, is fixedly connected to the top of the steam discharge chamber shell 19.

[0040] A vertically arranged side spoiler 3 is fixedly connected between the outer ends of the spoiler 3.

[0041] The side wall of the side spoiler 3 is in frictional contact with the inner wall of the drying tank 1.

[0042] The connecting pipe assembly includes a connecting elbow 12 that is rotatably inserted into the medium discharge channel 11, and the outlet end of the connecting elbow 12 is connected to the heat exchange jacket 15 through a pipe 13.

[0043] An inlet cylinder 17 and an outlet cylinder 18, which connect to the heat exchange jacket 15, are fixedly connected to the outer wall of the heat exchange jacket 14. The inlet cylinder 17 is connected to the pipe 13.

[0044] The inlet cylinder 17 is located near the lower end of the heat exchanger jacket 14, and the outlet cylinder 18 is located near the upper end of the heat exchanger jacket 14.
