Embodiment 1

[0034] See Figure 1-7 The continuous drying system for slurry or powder provided in this embodiment includes: a drying host, and a collection system for collecting volatiles connected to the exhaust port of the drying host.

[0035] The drying host includes: a rotating shaft 1, an annular chamber 2 arranged up and down in multiple layers; The scraper 3; there is a gap between two adjacent annular chambers 2, so that the bottom plate of the annular chamber 2 can directly exchange heat with the heat-conducting medium or the heating wire, thereby ensuring the drying effect.

[0036] Two adjacent annular cavities 2 are sealed and connected by a blanking channel 4; the bottom of the bottom plate of each annular cavity 2 is provided with a heating wire 5, or each annular cavity is arranged in a thermal fluid container 6, or the The drying host is set above a combustion furnace 14; the top annular cavity is provided with a material inlet and an exhaust port for discharging volatile...

Embodiment 2

[0047] The working method of the continuous drying system of the slurry or powder described in the above-mentioned embodiment 1, comprising:

[0048] A. Connect the heating wire 5 to the power supply for heating, or continuously circulate the heat-conducting liquid into the heat-conducting liquid container 6, or use the combustion furnace 14 located at the bottom of the drying host to heat each annular cavity 2; The temperature of the annular cavity 2 is suitable to reach 50-700° C. (the specific temperature needs to be selected according to different materials).

[0049] B. Input the slurry through the pump or the powder through the screw conveyor 13 from the material inlet on the annular cavity on the top floor, and at the same time turn on the main motor 15 to drive the rotating shaft 1 to rotate;

[0050] C. Under the action of the rotation of the scrapers 3 on each layer, the slurry or powder is heat-exchanged layer by layer, dried and falls, and finally discharged from t...

Embodiment 3

[0057] Such as Figures 8 to 9 , the present embodiment provides a continuous drying system for liquid materials, including a drying host, and a collection system for collecting volatiles connected to the exhaust port of the drying host.

[0058] The drying host includes: multi-layer cavities 20 arranged up and down; there is a gap between two adjacent cavities 20, which are sealed and connected through a blanking channel; the bottom of each cavity 20 is provided with a heating wire 5, Or each cavity 20 is set in the heat transfer fluid container, or the bottom of the drying host is equipped with a combustion furnace; the cavity on the top layer is provided with a material inlet and an exhaust port, and the bottom of the cavity on the bottom layer is provided with a discharge port.

[0059] In the two adjacent cavities 20, the 1 to 4 blanking openings on the bottom plate of the upper cavity are connected to the openings on the top plate of the lower cavity through the blanking...

Abstract

The invention relates to a slurry or powder continuous drying system. The slurry or powder continuous drying system can be applied to evaporation collection on phosphorus in the phosphorus slurry and slags, residual liquid treatment of calcium oxide or calcium chloride and benzoyl chloride, drying of chemical products, comprehensive recycling of three wastes and the like. The slurry or powder continuous drying system comprises a drying host which comprises a rotating shaft and a plurality of layers of annular chambers; the plurality of layers of annular chambers are formed up and down and matched with the rotating shaft through a center through hole in a flexible sealing mode; scrappers which are distributed in the annular chambers respectively are fixed on the rotating shaft; a gap is formed between the two adjacent annular chambers which are connected through a discharging channel in a sealing mode; the annular chambers are formed in a heat conduction liquid container; the top layer of annular chamber is provided with a material inlet and an air outlet; the bottom of the bottom layer of annular chamber is provided with a discharging hole. The slurry or powder continuous drying system is suitable for continuous drying of slurry and powder, the production efficiency is high, and the environment-friendly, safe and energy-saving effects are achieved. The slurry and the powder are large in volatilization area through evaporation layer by layer and accordingly the evaporation efficiency of volatile matter is high and meanwhile the recycling rate of the volatile matter is high.

Description

technical field [0001] The invention relates to a continuous drying system for slurry or powder, which can be applied to the evaporation and collection of phosphorus in phosphorus sludge and slag, the treatment of calcium oxide or calcium chloride, and the residual liquid of benzoyl chloride, the drying of chemical products, and the three wastes Comprehensive recycling, etc. Background technique [0002] In the prior art, the production of yellow phosphorus by the electric furnace method will produce wastes such as phosphorus sludge and phosphorus slag, and a considerable part of the yellow phosphorus in the discarded phosphorus sludge and phosphorus slag has not been completely refined, which causes a waste of resources. [0003] Existing methods for recovering yellow phosphorus include steam filtration, dry steaming, chemical reagent reaction, etc.; the steam filtration method is to put phosphorus sludge and slag into a container and heat continuously with steam to dissolv...
