Description

Technical Field

[0001] This utility model relates to a continuous drying device for glyphosate. Background Technology

[0002] Currently, the production of glyphosate using the glycine-dimethyl ester method requires drying the resulting wet glyphosate powder. Chinese patent CN117258393A discloses a filtration and drying device for glyphosate production. This device uses a fan to blow cold outside air into a heating chamber, where the air is heated to form hot air. This hot air is then blown out through nozzles to dry the glyphosate. However, the hot air blown into the chamber must eventually be exhausted. This device lacks dust removal treatment for the exhausted hot air, which carries a certain amount of glyphosate powder. Directly discharging this untreated hot air will pollute the environment and affect the health of nearby people, failing to meet environmental protection requirements. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a continuous glyphosate drying device that can remove dust from the discharged hot air, thereby preventing the discharged hot air from carrying glyphosate powder, thus avoiding environmental pollution and avoiding impact on human health, and meeting environmental protection requirements.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a glyphosate continuous drying equipment, including a drying tower, a feeding device, a crushing device, an air heating device, a cyclone separator, a bag filter, an induced draft fan and a spray dust collector;

[0005] The feeding device is connected to the drying tower and is used to transport glyphosate wet powder into the drying tower;

[0006] The pulverizing device is connected to the bottom of the drying tower;

[0007] The air outlet of the air heating device is connected to the pulverizing device, and the air inlet of the air heating device is used to introduce air.

[0008] The outlet of the drying tower is directly or indirectly connected to the inlet of the cyclone separator;

[0009] The outlet of the cyclone separator is connected to the inlet of the bag filter.

[0010] The outlet of the bag filter is connected to the inlet of the induced draft fan;

[0011] The outlet of the induced draft fan is connected to the inlet of the spray dust collector.

[0012] Furthermore, the outlet of the drying tower is indirectly connected to the inlet of the cyclone separator via a secondary dryer; wherein, the outlet of the drying tower is connected to the inlet of the secondary dryer, and the outlet of the secondary dryer is connected to the inlet of the cyclone separator.

[0013] Furthermore, in order to filter the air, a filter screen is installed at the air inlet of the air heating device.

[0014] Furthermore, the air heating device is a steam heat exchanger.

[0015] Furthermore, the feeding device is a screw feeder.

[0016] Furthermore, the glyphosate continuous drying equipment also includes a first hopper and a first discharge valve; wherein, one end of the first discharge valve is connected to the discharge port at the bottom of the cyclone separator, and the other end of the first discharge valve is connected to the feed port of the first hopper.

[0017] Furthermore, a second discharge valve is connected to the discharge port of the first hopper.

[0018] Furthermore, the glyphosate continuous drying equipment also includes a discharge auger, which is connected to the discharge port at the bottom of the bag filter.

[0019] Furthermore, the glyphosate continuous drying equipment also includes a second hopper and a third discharge valve; wherein, one end of the third discharge valve is connected to the outlet of the discharge auger, and the other end of the third discharge valve is connected to the inlet of the second hopper.

[0020] Furthermore, the discharge port of the second hopper is connected to an on / off valve.

[0021] After adopting the above technical solution, the feeding device first receives glyphosate wet powder from the outside. The feeding device is used to transport the received glyphosate wet powder into the drying tower. The glyphosate wet powder fed into the drying tower falls to the bottom of the tower in a clump and is crushed by the crushing device. Under the suction action of the induced draft fan, the outside cold air enters the air heating device and is heated to form hot air. After entering the crushing device, the hot air carries the crushed glyphosate wet powder into the drying tower for drying. The dried glyphosate powder enters the cyclone separator with the hot air. In the cyclone separator, most of the glyphosate powder falls to the bottom of the cyclone separator due to gravity so that it can be discharged from the discharge port at the bottom of the cyclone separator. A small portion of fine glyphosate powder particles in the cyclone separator will enter the bag filter dust collector from the air outlet of the cyclone separator with the hot air. A baghouse dust collector is used to filter, capture, and recover glyphosate powder from hot air. The filtered hot air is then drawn from the outlet of the baghouse dust collector by an induced draft fan to a spray dust collector for dust removal. The dust-removed air is then discharged from the outlet of the spray dust collector. This embodiment of the application can continuously dry wet glyphosate powder, which is beneficial for large-scale automated production. Furthermore, the baghouse dust collector filters and removes glyphosate powder from the hot air, while the spray dust collector removes dust from the hot air, preventing the discharged hot air from carrying glyphosate powder, thus avoiding environmental pollution and potential harm to human health, and meeting environmental protection requirements.

The dust-removed air is discharged from the outlet of the spray dust collector 8. This embodiment of the application can continuously dry glyphosate wet powder, which is beneficial for large-scale automated production. Furthermore, the bag filter 6 can filter and remove glyphosate powder from the hot air, and the spray dust collector 8 can also remove dust from the hot air, preventing the discharged hot air from carrying glyphosate powder, thereby avoiding environmental pollution and protecting human health, and meeting environmental protection requirements. More specifically, when the drying tower 1 cannot meet the drying requirements of glyphosate wet powder, the secondary dryer 9 needs to be installed. The specific structures of the drying tower 1, the secondary dryer 9, and the pulverizing device 3 are all prior art well known to those skilled in the art, and will not be described in detail in this embodiment.
