Abstract
The utility model discloses a melamine unloading device arranged in crystallizers, which is characterized in that the middle part of a melamine fine product conveying tube (1) is mounted with a three-way reversing valve (2) which one inlet is connected with one end of a material conveying host (3), the another end of the host is sheathed with a spraying faucet (4) connected with an air tube (5), the lower part of the melamine conveying tube at the back of the three-way reversing valve is connected with the upper part of a melamine chamber (8) which upper part is provided with a bag dust cleaner (7), and an induced fan (6) connected with a power supply is arranged above the dust cleaner. The melamine unloading device can prevent the product from being polluted to hold product level, can avoid manual unloading to save time and force, can reduce maintenance time and can improve running efficiency.
Description
Technical field
The utility model relates to a kind of granular goods unloading mechanism, and especially a kind of low-pressure vapor phase quenching is produced the trimeric cyanamide unloading mechanism in the trimeric cyanamide crystallizer.
Background technology
The equipment that the low-pressure vapor phase quenching method is produced trimeric cyanamide needs frequent parking maintenance, and each maintenance all will unload a large amount of trimeric cyanamides that storage is stayed in the crystallizer, unloading is all by manually packing trimeric cyanamide in the crystallizer at present, be transported to outside the crystallizer, be discharged to ground, be transported to trimeric cyanamide with fork truck then and pack the room, this had both increased labor strength, pollute easily again, reduce product hierarchy, reduce economic benefit.When stopping simultaneously just in the crystallizer temperature higher, need in the device to be crystallized temperature can carry out operation after reducing, thereby when carrying out the crystallizer maintenance, need the time of stopping, prolonged repair time and equipment operating efficiency.
The utility model content
The purpose of this utility model is to overcome the prior art deficiency, provide a kind of trimeric cyanamide grade of avoiding to reduce, shorten the parking maintenance time, alleviate the interior trimeric cyanamide unloading mechanism of crystallizer of labor strength, the purpose of this utility model realizes by following technical proposals: the utility model comprises trimeric cyanamide transfer lime and warehouse, at trimeric cyanamide finished product transfer lime middle part one three-way diverter valve is installed, ingress of reversing valve is connected with convey materials flexible pipe one end, halter is sprayed in flexible pipe the other end socket one, spraying halter links to each other with carrying blast main, trimerization ammonia amine transport pipe bottom behind the three-way diverter valve is connected with trimeric cyanamide warehouse top, trimeric cyanamide warehouse top is provided with sack cleaner, and the fly-ash separator top is provided with an induced draft fan that links to each other with power supply.
Open during use and carry the blast main switch, T-valve and induced draft fan get final product.
The utility model utilizes the air draught effect that powdery trimeric cyanamide in the crystallizer is picked up on the one hand, make the trimeric cyanamide warehouse produce negative pressure after being located at the induced draft fan unlatching on the trimeric cyanamide warehouse bag shape fly-ash separator on the other hand, make the powdery trimeric cyanamide enter warehouse along the trimeric cyanamide transfer lime, the trimeric cyanamide that enters warehouse is deposited in the warehouse by sack cleaner and air separation, air is then extracted out by blower fan, and the trimeric cyanamide in the warehouse packs by automatic packing machine.This device directly is transported to the trimeric cyanamide in the crystallizer in the warehouse by pipeline, again by putting in storage after the automatic quantitative packing machine quantitative package, avoided product contaminated and downgrade, removed the artificial unloading time-consuming problem of requiring great effort from, this device has shortened the repair time greatly simultaneously, has improved the operation factor of equipment.
From above-mentioned situation as can be known, the purpose of this utility model can realize.

Fig. 1 is the utility model configuration diagram;
Fig. 2 sprays the halter configuration diagram for the utility model.
Embodiment
As shown in Figure 1, at trimeric cyanamide transfer lime 1 middle part one three-way diverter valve 2 is installed, inlet of three-way diverter valve is with the 3 one end sockets of convey materials flexible pipe or fixedly connected, spray halter 4 in delivery hose the other end socket one, as shown in Figure 2, spray halter by collar seat 12, endless tube 11 and and the seamless tube group 9 of 10 of top center pipes be welded, said seamless tube group 9 is that several seamless tubes constitute, with arc is good, and present embodiment is selected four arc seamless tubes for use.The tube chamber of top center pipe 10, endless tube 11 and seamless tube communicates, spray halter and be located at below, crystallizer exit, spraying halter 4 links to each other with carrying blast main 5, pressurized air is delivered to the pipe core 10 that sprays halter by carrying air line 5, inject again in the convey materials flexible pipe, trimeric cyanamide transfer lime bottom behind the three-way diverter valve is connected with trimeric cyanamide warehouse 8 tops, and trimeric cyanamide warehouse top is provided with sack cleaner 7, and the fly-ash separator top is provided with the induced draft fan 6 that links to each other with power supply.
Claims (2)
1, trimeric cyanamide unloading mechanism in a kind of crystallizer, comprise trimeric cyanamide transfer lime and warehouse, it is characterized in that: one three-way diverter valve (2) is installed at trimeric cyanamide finished product transfer lime (1) middle part, ingress of reversing valve is connected with convey materials flexible pipe (3) one ends, halter (4) is sprayed in flexible pipe the other end socket one, spraying halter links to each other with carrying blast main (5), trimerization ammonia amine transport pipe bottom behind the three-way diverter valve is connected with trimeric cyanamide warehouse (8) top, trimeric cyanamide warehouse top is provided with sack cleaner (7), and the fly-ash separator top is provided with an induced draft fan that links to each other with power supply (6).
2, trimeric cyanamide unloading mechanism in a kind of crystallizer according to claim 1, it is characterized in that: said injection halter by collar seat (12), endless tube (11) and and top center pipe (10) between the seamless tube bond pads form, the tube chamber of endless tube, pipe core and seamless tube communicates.
