The utility model discloses can ensure when the solid charging means uses and can not get into the air and wet after using, can save the nitrogen gas quantity again, can also improve equipment's safe life.
Description
Technical Field
The utility model relates to a solid charging means pressure-fired protection device.
Background
In chemical production, when a metal material is used and the working condition requirement of the solid feeder cannot be met, a high polymer material (such as a PP material) is often selected. The high molecular material has good corrosion resistance but small bearing capacity. When water-repellent reaction is encountered, the solid feeder is generally protected by introducing nitrogen after use. Therefore, the phenomena that the flow of inlet and outlet nitrogen is inconsistent, the outlet bleed air is large, and the feeder is in negative pressure often occur, so that air permeates, the protection effect cannot be achieved, and the nitrogen consumption is increased. In addition, water droplets generated by air infiltration can cause corrosion of the plumbing equipment, reducing the safe service life of the equipment.
Disclosure of Invention
In order to solve the problem, the utility model provides a little, the solid charging means pressure-fired protection device of high safety that the solid charging means does not receive the tide of nitrogen gas consumption.
The technical scheme of the utility model is that:
the utility model provides a high safe solid charging means pressure-fired protection device which characterized by: the device comprises a nitrogen buffer tank, wherein a regulating valve is arranged at a nitrogen inlet of the nitrogen buffer tank, a pressure transmitter and a pressure relief device are arranged on the nitrogen buffer tank, a nitrogen valve is arranged at an outlet of the nitrogen buffer tank and divided into a plurality of paths, the nitrogen valve is connected to each solid feeder respectively, and the bottom of each solid feeder is connected to a groove or a kettle.
But the sealed lid of solid charging means, its top installation switch, the sealed gas cock of aerifing of covering the installation and being connected with the nitrogen gas valve of sealing, solid charging means bottom is through installing valve, auger charging means or vibrations charging means and connecing groove or cauldron.
The regulating valve is interlocked with the pressure transmitter, and the regulating valve automatically regulates the size of the switch according to the pressure.
The pressure relief device can be a safety valve or other forms, and can realize the following functions: when the pressure of the buffer tank exceeds the safe pressure, the pressure relief device is automatically opened, and when the pressure of the buffer tank is reduced to the safe pressure, the pressure relief device is automatically closed.
The utility model has the advantages that: the solid feeder can not enter air to damp when and after being used, can save the nitrogen consumption, and can prolong the safe service life of equipment.
Drawings
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The utility model discloses the structure is as shown in fig. 1, and nitrogen gas source is through governing valve 1 to nitrogen buffer tank 3, ann has pressure transmitter 2 and pressure relief device 4 on the buffer tank 3, and buffer tank 3 exports and divides the multichannel interface ann to have nitrogen gas valve 5, and nitrogen gas valve 5 connects respectively to the gas nozzle 7 of aerifing on each solid charging means 6, and 6 bottom installation valves 8 of solid charging means connect to groove (cauldron) 9 again. The top of the solid feeder is provided with a sealing cover capable of being opened and closed, the sealing cover is provided with an inflation air nozzle 7 connected with a nitrogen valve, and the bottom of the solid feeder is connected to the tank or the kettle through an installation valve 8 (or an auger feeder or a vibration feeder).
The regulating valve is interlocked with the pressure transmitter, and the regulating valve automatically regulates the size of the switch according to the pressure.
The utility model discloses the theory of operation does: setting safe use pressure according to the pressure-bearing condition of the solid feeder 6, and then setting a nitrogen protection pressure range, namely a lower pressure limit and an upper pressure limit, wherein the upper pressure limit is smaller than a safe pressure value; the pressure value of the pressure relief device 4 of the nitrogen buffer tank 3 is set as a safe pressure value; when the pressure of the buffer tank 3 exceeds the safe pressure, the pressure relief device 4 is automatically opened to relieve the pressure, and when the pressure of the buffer tank 3 is reduced to be lower than the safe pressure, the pressure relief device 4 is automatically closed. The buffer tank air inlet regulating valve 1 automatically regulates the size of a switch according to the pressure upper limit and the pressure lower limit set by the pressure in the tank, the valve 1 is closed when the pressure reaches the pressure upper limit, and the valve 1 is opened when the pressure is reduced to the pressure lower limit; the solid feeder 6 can be protected after the pressure of the nitrogen buffer tank 3 is normal.
During operation, the sealing cover is opened, solid materials are added into the solid feeder 6, then the sealing cover is closed, the inflating nozzle 7 is connected to the nitrogen buffer tank 3 through the air pipe, and protection is implemented by opening the split nitrogen valve 5. When the feeder 6 feeds materials downwards, nitrogen automatically supplements pressure; after the feeding is finished, the lower valve 8 is closed, and the nitrogen is filled with normal protection. If the solid feeder 6 has leakage, the pressure of the nitrogen buffer tank 3 can be slowly reduced, and the regulating valve 1 can be automatically opened to supplement nitrogen when the pressure reaches the lower limit value, and the operation is carried out according to the automatic program. If the pressure supplementing frequency of the nitrogen buffer tank 3 is too high, the solid feeder 6 has a large leakage point, and leakage supplementation needs to be checked in time.
