Abstract
The utility model discloses a discharge air distributing device of rake drying equipment. The discharge air distributing device comprises a rake dryer, a suction tank and a vacuum pump, wherein a discharging opening of the rake dryer is connected with a feeding opening of the suction tank through a conveying pipe, and the vacuum pump is connected with the suction tank. The discharge air distributing device is characterized in that an air distributing device is connected onto the conveying pipe; the air distributing device consists of an air flow passage, a plug and an elastic support, wherein one end of the elastic support is fixed in the air flow passage, and the other end of the elastic support is connected with the plug, and the plug is suspended in the air flow passage; and a neck part with a diameter smaller than that of the plug is arranged in the air flow passage in the air flow direction. The discharge air distributing device of rake drying equipment provided by the utility model has simple structure and reasonable arrangement, and can satisfactorily solve the blockage problem occurred in dry powder discharging process.
Description
Technical field
The utility model relates to a kind of rake formula drying equipment discharging air distributing device.
Background technology
In the chemical process, behind the dry removal of the material process vacuum rake type solvent, be the dry powder shape, change next procedure over to, need to adopt certain discharging method that the dry powder in the rake type drier is transferred in the suction jar of next procedure use for making material.
The method that general rake formula drying equipment discharging is adopted is: be connected with conveying pipeline between rake type drier and the suction jar, utilize vavuum pump that the suction jar is vacuumized, thereby material is transferred to the suction jar from rake type drier.But, stop up the conveying pipeline between rake type drier and the suction jar especially easily, thereby plugging fault often appears in the method in use because material is the dry powder shape.In order to solve the material blockage problem, people improve said method, as shown in Figure 1, add water and make it form the slurries outflow in rake type drier, by pump solidliquid mixture are inputed in the suction jar together.There is following defective in this method: 1, the rake type drier internal temperature is than higher, and the coolant-temperature gage that adds is lower, and temperature difference cataclysm causes the distortion of equipment ladle body easily, reveals; 2, the oxidizing substance in the material also can form the crystalline phase corrosion to equipment after meeting water, shortens the service life of equipment.
The utility model content
The utility model purpose: the purpose of this utility model is at the deficiencies in the prior art, and a kind of rake formula drying equipment discharging air distributing device that can solve the dry powder obstructing problem again can damage equipment is provided.
Technical scheme: rake formula drying equipment discharging air distributing device described in the utility model, comprise rake type drier, suction jar and vavuum pump, the discharging opening of described rake type drier is connected by conveying pipeline with the charging aperture of described suction jar, described vavuum pump is connected with described suction jar, vavuum pump makes the dry material of rake type drier kind enter the suction jar under the effect of pressure to vacuumizing in the suction jar; Also be connected with an air distributing device on the described conveying pipeline, make material and gas satisfy certain gas-solid ratio; Described air distributing device is made of gas channel, stopper and elastic bearing, and a described flexibly mounted end is fixed in the passage, and the other end is connected with stopper, and stopper is suspended in the described gas channel; In the described gas channel, also be provided with the neck of diameter less than the stopper diameter along airflow direction.When occur stopping up in the conveying pipeline, it is big that the current rate in the air distributing device becomes, and the neck that stopper is moved to gas channel in the air-flow effect is channel seal, makes that material is dredged under pressure in the conveying pipeline.
Rationally distributed in order to make, good connecting effect, the import department of described conveying pipeline is divided into two branch roads, and a branch road connects the discharging opening of described rake type drier, and another branch road connects the air outlet of described air distributing device.Certainly, also a three-way interface can be set, be connected with the air outlet of described air distributing device and the discharging opening of rake type drier respectively in described conveying pipeline end.
When conveying pipeline occur to be stopped up, the obturation effect in the air distributing device was good, and the stopper in the described air distributing device is a spherical shape.
Simple in structure in order to make, the convenient connection, described elastic bearing is a spring.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, the utility model product structure is simple, and is rationally distributed, can solve the blockage problem in the dry powder discharging process well; 2, the utility model device does not in use damage equipment, guarantees the service life of equipment, prevents superpressure hidden danger that the wet method discharging causes and the equipment crystalline phase is corroded.

The specific embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
Shown in Fig. 2,3, a kind of rake formula drying equipment discharging air distributing device, comprise rake type drier 1, suction jar 2 and vavuum pump 3, the discharging opening of described rake type drier is connected by conveying pipeline with the charging aperture of described suction jar, described vavuum pump is connected with described suction jar, also is connected with an air distributing device 4 on the described conveying pipeline; Described air distributing device is made of gas channel 5, spherical stopper 6 and elastic bearing 7, and described elastic bearing 7 is a spring, and the one end is fixed in the passage 5, and the other end is connected with spherical stopper 6, and stopper 6 is suspended in the described gas channel 5; In the described gas channel 5, also be provided with the neck 8 of diameter less than the stopper diameter along airflow direction; The import department of described conveying pipeline is divided into two branch roads, and a branch road connects the discharging opening of described rake type drier, and another branch road connects the air outlet of described air distributing device.
During operate as normal, spherical stopper 6 is equilibrated at the neck upper end of gas channel under the effect of spring and air-flow power, and the dry powder in gas and the rake type drier is with in certain gas-solid ratio input suction jar 2; When the dry powder obstruction appearred in the discharging opening of rake type drier, the air-flow in the air distributing device 4 can become greatly, and stopper 6 moves downward under the air-flow effect, and neck is blocked, and the pressure in the conveying pipeline diminishes, and the discharging opening dry powder of rake type drier is dredged under pressure.
As mentioned above, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make various variations in the form and details to it.
