Terephthalaldehyde adopts the oxidation of methenamine method to be prepared mostly, after preparing first finished product, need to dry, at present, the oven dry of terephthalaldehyde is mainly to adopt steam drying, at a bulk container outer wall that is placed with terephthalaldehyde, lead to steam around, yet, difficult control of temperature due to steam, may reach very high, and the fusing point of terephthalaldehyde between 115～116 ℃, boiling point is within the scope of 245～248 ℃, too high temperature easily makes terephthalaldehyde generation oxidation reaction, and it is rotten that terephthalaldehyde is occurred.In addition, also there is following shortcoming in steam drying: the production efficiency of steam is low, and the utilization rate of steam heat is low, needs larger heat transfer area, need to guarantee higher travelling speed, thereby otherwise heat will lose the decline that causes temperature from system simultaneously.
Utility model content
The utility model provides a kind of hot water circuit drying unit of terephthalaldehyde, to solve existing steam drying, exists excess Temperature easily to make terephthalaldehyde that the shortcomings such as rotten occur.
The utility model adopts following technical scheme:
The hot water circuit drying unit of terephthalaldehyde, comprise bipyramid baking oven, supporting seat, water inlet pipe, outlet pipe and hot-water heating system, described bipyramid baking oven is rotatably set up on described supporting seat, bipyramid baking oven comprises jacket body and outer cylinder body, jacket body is provided with a raw material and imports and exports, this raw material is imported and exported and is sealed by a lid, the closed cavity that is fixedly connected with and forms a dress hot water between described jacket body and outer cylinder body, described hot-water heating system is connected with described closed cavity respectively by described water inlet pipe and outlet pipe.
Particularly, be welded with the first turning cylinder and the second turning cylinder on the lateral wall of outer cylinder body, described the first turning cylinder and the second turning cylinder are in passing on the same horizontal line at this outer cylinder body center.
Further, described the first turning cylinder and the second turning cylinder are located at respectively the both sides of described supporting seat by a bearing fixed mount, the first turning cylinder is rotated by a driven by motor, the second turning cylinder boring, described water inlet pipe and outlet pipe through the second inside of stating turning cylinder be connected with described closed cavity.
Further, on described water inlet pipe and between described hot-water heating system, be provided with a suction pump.
Again further, described hot-water heating system is a hot-water boiler.
From the above-mentioned description to the utility model structure, compared to the prior art, the utlity model has following advantage: drying unit of the present utility model, employing hot water is dried, temperature is comparatively gentle, terephthalaldehyde can be because of not oxidized and rotten, the bipyramid baking oven that terephthalaldehyde raw material is housed constantly rotates, accelerate the drying rate of raw material, and dry comparatively even, simultaneously, the water that temperature reduces is back to hot-water heating system and reheats from outlet pipe, realize recycling of hot water, the utilization rate of heat is high, reduced the cost of hot oven dry, in addition, this drying unit is simple in structure, can realize the oven dry to a large amount of terephthalaldehyde raw materials, also applicable to other easily oven dry of oxidized raw chemical material.
Accompanying drawing explanation
