Abstract
Description
Technical Field:
[0001] The utility model relates to a drying device in the fields of food, medicine and chemical industry, in particular to a heat exchange plate of an anti-overflow belt dryer. Background Art:
[0002] In industrial production, there are many conventional drying methods and drying devices. Among them, the belt dryer has gradually developed in China in the past more than 10 years, and its application fields are becoming wider and wider. It started from the drying of traditional Chinese medicine extracts and has gradually been used in industries such as food, new energy, and chemical industry.
[0003] The liquid belt dryer can realize continuous feeding and discharging, and is suitable for drying various liquids, high-viscosity raw materials, and products with high requirements for heat sensitivity, such as traditional Chinese medicine extracts, various plant extracts, fructooligosaccharides, instant tea powder, pharmaceutical and chemical intermediates, etc., and is widely used in other industries such as pharmaceuticals, food, chemicals, and biological products. At the same time, according to the material characteristics requirements of different customers, the evaporation temperature, working vacuum degree, drying time, and moisture content of the dry powder can be adjusted according to process parameters to meet the process requirements of different raw materials.
[0004] The liquid belt dryer feeds the material with a certain fluidity onto the conveyor belt through a cloth device, and a heating plate is arranged under the conveyor belt. As the conveyor belt moves and the heating process progresses, the liquid phase continuously evaporates, the moisture and heat of the material are continuously removed, and the solid phase is intercepted. The dried material will form a porous and loose shape. According to different drying process requirements, the dryer can be provided with several heating zones and cooling zones, and the temperatures of the heating zones and cooling zones are adjustable. The discharging end of the dryer is equipped with a scraper and a cutting device, and is mechanically conveyed to a vacuum crushing and granulating system. The sizes of the powder and granules can be adjusted according to the needs of customers, so as to meet the requirements of users for the mesh number of products.
[0005] Since the liquid has a certain fluidity, when the material is distributed on the conveyor belt, the liquid will flow to a certain extent. When it flows to the edge of the conveyor belt, the material is very likely to flow out of the conveyor belt and fall between the conveyor belt and the heat exchange plate, resulting in situations such as the conveyor belt slipping and affecting production. If the amount of cloth is reduced to prevent liquid overflow, the production capacity will decrease. Summary of the Invention:
[0006] The technical problem to be solved by the utility model is to solve the problems existing in the above-mentioned prior art, and provide a heat exchange plate of an anti-overflow belt dryer, which effectively blocks the flow of the material with good fluidity to the edge of the conveyor belt by raising the edge of the conveyor belt. At the same time, the liquid material at the edge of the conveyor belt is heated and solidified into an edge baffle to further prevent the material from overflowing.
[0007] The technical solution adopted by the utility model is as follows: a heat exchange plate of an anti-overflow belt dryer, which comprises a heat exchange plate body of the belt dryer and a heat medium pipe for heating the heat exchange plate body installed at the bottom of the heat exchange plate body of the belt dryer. Both ends of the heat medium pipe for heating the heat exchange plate body are respectively provided with a heat medium inlet and a heat medium outlet, and heating belts or heating pipes are installed at both sides of the top edge of the heat exchange plate body of the belt dryer.
[0008] In the above technical solution, the installed heating belts or heating pipes are installed along both sides in the length direction of the heat exchange plate body of the belt dryer.
[0009] In the above technical solution, the installed heating belts or heating pipes are higher than the plane of the crawler of the belt dryer.
[0010] In the above technical solution, both ends of the heating belts or heating pipes are respectively provided with a heat medium inlet of the heating pipe belt and a heat medium outlet of the heating pipe belt.
[0011] In the above technical solution, the heat medium is steam, heat-conducting oil, hot water or superheated water.
[0012] Advantages and effects of the utility model:
[0013] 1. The heating belts or heating pipes installed along both sides of the top edge of the heat exchange plate body of the belt dryer in the length direction are higher than the plane of the crawler of the belt dryer, which makes the two edges of the crawler bulge upward.
[0014] Effectively prevent the liquid material with good fluidity from overflowing to the outside of the edge, thus avoiding the overflowing liquid material from falling between the crawler and the top flat plate of the heat exchange plate, and avoiding the adhesion between the crawler and the heat exchange plate after the overflowing liquid material is dried, so as to prevent the crawler from slipping and affecting production.
[0015] 2. The newly installed heating belts or heating pipes can heat the materials at the edge of the crawler, so that the liquid materials at the edge of the crawler can be dried as soon as possible. After they are dried and solidified, the solidified materials at the edge of the crawler actually become overflow baffles, blocking the liquid materials in the middle of the crawler from flowing outwards.
[0016] 3. Due to the elevation of the edge of the crawler and the formation of a baffle by the solidification of the materials at the edge of the crawler, the overflow of the materials with good fluidity is prevented, so that the cloth feeding amount in production will not be reduced, and the unit area production capacity will not be affected.
