Description
Technical Field
The utility model relates to a limestone flour sampling technical field of thermal power plant, more specifically the theory that says so relates to a limestone flour sampling device.
Background
Limestone-gypsum wet desulphurization technology is a flue gas desulphurization technology widely used by power plants at present, wherein limestone slurry comes from a limestone powder bin system. The limestone powder bin system is used for storing, weighing and discharging the limestone-gypsum method desulfurization device in the power plant, and can be used as a receiving unit and a feeding unit. It forms a set of complete limestone powder bin system together with a self-unloading sealing tank car, a limestone slurry pool and the like. The quality of the limestone powder directly influences the quality of the gypsum slurry and the desulfurization reaction efficiency, and is an important index which is related to environmental protection and reaches the standard.
At present, the limestone powder is mainly pulverized by a self-unloading sealing tank car to a limestone powder bin for storage, and the sampling and testing of the powder from each tank car are required. At present, manual sampling is mostly used in the sampling work, each tank vehicle is divided into a front sampling part, a middle sampling part and a rear sampling part for three times, the labor cost is consumed, and risks that raised dust harms environmental sanitation during sampling, sampling personnel are healthy, samples are artificially and artificially replaced, and the like exist.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical defect, the utility model provides a limestone powder sampling device.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a limestone powder sampling device comprises a powder bin upper powder pipe, wherein the upper end of the powder bin upper powder pipe is communicated with a powder bin, and the lower end of the powder bin upper powder pipe is communicated with a self-discharging sealing tank car; the powder feeding pipe of the powder bin is communicated with a sampling pipe, a sampling manual door is arranged on the sampling pipe, and one end of the sampling pipe, which is far away from the powder feeding pipe of the powder bin, is communicated with a sampling bottle; install the solenoid valve on the sampling pipe, solenoid valve and time controller electric connection, sampling pipe intercommunication between sampling hand door and the solenoid valve has the intake pipe, installs manometer and compressed air control valve in the intake pipe, and the intake pipe is kept away from the one end of sampling pipe and is installed the compressed air interface, and the compressed air interface passes through trachea intercommunication compressed air source.
Furthermore, the material of sampling bottle is transparent organic glass.
Further, a detachable padlock is arranged on the sampling bottle.
The utility model has the advantages that: the problem that the environmental sanitation and the personnel health are harmed by manually sampling the raised dust of the limestone powder is avoided; the sampling bottle is provided with a disassembly lock, so that sampling behavior such as sample exchange and the like caused by taking the sampling bottle away by non-sampling personnel is avoided; sampling pipe intercommunication intake pipe prevents that sampling pipe from blockking up.
Drawings

in the figure, 1, a sampling tube; 2. sampling a manual door; 3. an electromagnetic valve; 4. a padlock; 5. sampling a bottle; 6. a time controller; 7. a pressure gauge; 8. a compressed air interface; 9. a compressed air control valve; 10. an air inlet pipe; 11. powder tube is gone up to powder storehouse.
Detailed Description
The technical solution of the embodiment of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiment of the present invention, as shown in fig. 1, a limestone powder sampling device includes a powder bin upper powder pipe 11, an upper end of the powder bin upper powder pipe 11 is communicated with a powder bin, and a lower end of the powder bin upper powder pipe 11 is communicated with a self-discharging sealing tanker; the powder feeding pipe 11 of the powder bin is communicated with a sampling pipe 1, a sampling manual door 2 is installed on the sampling pipe 1, one end, far away from the powder feeding pipe 11 of the powder bin, of the sampling pipe 1 is communicated with a sampling bottle 5, the sampling bottle 5 is made of transparent organic glass, the transparent organic glass is convenient for observing a sample, environmental pollution caused by limestone powder overflowing after the sampling amount is too large is prevented, a detachable padlock 4 is installed on the sampling bottle 5, the padlock 4 is used for locking the sampling bottle 5, a special key is needed for opening, non-sampling personnel can be prevented from contacting the sample, and the false behaviors such as sample replacement and the like are avoided; install solenoid valve 3 on sampling pipe 1, solenoid valve 3 and time controller 6 electric connection, sampling pipe 1 intercommunication between sampling hand door 2 and the solenoid valve 3 has intake pipe 10, installs manometer 7 and compressed air control valve 9 on the intake pipe 10, and intake pipe 10 is kept away from the one end of sampling pipe 1 and is installed compressed air interface 8, and compressed air interface 8 passes through trachea intercommunication compressed air source.
In the embodiment, the self-discharging sealed tank truck pumps limestone powder to the powder bin through the powder feeding pipe 11 of the powder bin; the sampling manual door 2 is in a normally open state, and the time controller 6 controls the switch of the electromagnetic valve 3 to control the sampling time and the sampling interval time each time. When the device has a fault, the sampling manual door 2 is manually closed, and the sampling device is isolated from the powder feeding pipe 11 of the powder bin. Compressed air can sweep sampling tube 1 through intake pipe 10, avoids sampling tube 1 to block up.
Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
