Description

Technical Field

[0001] This utility model relates to the field of storage technology, and in particular to a fly ash silo level gauge. Background Technology

[0002] Fly ash refers to the solid powder left after coal combustion. Fly ash can usually be reused in building materials such as cement and concrete to achieve the effect of waste utilization, and the performance of building materials such as cement and concrete with added fly ash is greatly improved.

[0003] Currently, the level gauges used in such closed silos in China include radio frequency admittance level gauges, radar level gauges, and rotary paddle level gauges. However, due to the characteristics of radio frequency admittance level gauges, such as easy material accumulation on the level detection rod; radar level gauges, such as requirements for the operating environment and the phenomenon of dust boiling in the silo when guiding material into it; and rotary paddle level gauges, such as ineffectiveness for highly fluid and lightweight materials, the above level gauges all have a relatively high error rate to varying degrees. At the same time, the above level gauges are relatively expensive. Therefore, this application discloses a fly ash silo level gauge. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing a fly ash silo level gauge.

[0005] This utility model is achieved through the following technical solution: a fly ash silo level gauge, including a tank body, the tank body is mounted on a support frame, a cylinder tube is provided through the upper side wall of the tank body, a plunger is inserted into the cylinder tube, a cover plate is connected to the outer end of the plunger, the cover plate is connected to a flange by bolts, the flange is connected to the outer end of the cylinder tube, a groove is provided on the end face of the cover plate away from the plunger, a retaining ring is movably provided in the groove, the retaining ring is sleeved on the outer end of the core rod, the core rod is slidably inserted into the plunger, the inner end of the core rod extends out of the plunger, the inner end of the core rod is connected to an air bladder, and the outer end of the core rod is connected to an air nozzle.

[0006] As a further improvement to the above solution, the cylinder tube is inclined on the outer wall of the tank, and the cylinder tube port is upward at 45-55°; this facilitates the sliding of the core rod inside the cylinder tube with the air bladder within the plunger. The core rod slides downward due to the gravity of the core rod and the air bladder, retaining ring, and air nozzle integrally connected to the core rod, causing the core rod to slide downward as the amount of fly ash decreases; if the core rod slides upward within the tank as the amount of fly ash increases, the top surface of the fly ash changes upward, and the rise of the fly ash top surface causes the air bladder to move upward, while the air bladder simultaneously causes the core rod to slide upward within the plunger.

[0007] As a further improvement to the above solution, the outer end of the plunger is threaded to the cover plate; the cover plate fixes the plunger inside the cylinder tube.

[0008] As a further improvement to the above scheme, the core rod is provided with scale lines to indicate the remaining amount of fly ash in the tank, and the air passage in the core rod extends to the end.

[0009] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, novel and unique concept. The remaining amount of fly ash in the tank changes, and the gas bladder filled with hydrogen changes the floating and sinking of the fly ash on the top surface of the tank. The floating and sinking of the gas bladder drives the core rod to slide and move within the plunger. The amount of fly ash in the tank is read by the scale on the core rod.

[0012] Figure 3 This is a schematic diagram of the first-direction installation structure of the level gauge. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figures 1 to 3 As shown, a fly ash silo level gauge includes a tank body 1, which is mounted on a support frame 2. A cylinder tube 3 is provided through the upper side wall of the tank body 1. A plunger 6 is inserted into the cylinder tube 3. The outer end of the plunger 6 is connected to a cover plate 9. The cover plate 9 is connected to a flange 4 by bolts. The flange 4 is connected to the outer end of the cylinder tube 3. A groove 12 is provided on the end face of the cover plate 9 away from the plunger 6. A retaining ring 10 is movably provided in the groove 12. The retaining ring 10 is sleeved on the outer end of a core rod 7. The core rod 7 is slidably inserted into the plunger 6. The inner end of the core rod 7 extends out of the plunger 6. The inner end of the core rod 7 is connected to an air bladder 8. The outer end of the core rod 7 is connected to an air nozzle 11.

[0015] As a further improvement to the above scheme, the cylinder tube 3 is inclined on the outer wall of the tank body 1, and the port of the cylinder tube 3 faces upward at 45 degrees; so as to facilitate the core rod 7 inside the cylinder tube 3 to slide in the plunger 6 along with the air bag 8. The core rod 7 slides downward through the gravity of the core rod 7 and the air bag 8, retaining ring 10 and air nozzle 11 integrally connected to the core rod 7, so that the core rod 7 slides downward as the amount of fly ash decreases; if the core rod 7 slides upward in the tank body 1 as the amount of fly ash increases, the top surface of the fly ash changes upward, the rise of the top surface of the fly ash drives the air bag 8 to move upward, and at the same time the air bag 8 drives the core rod 7 to slide upward in the plunger 6.

[0016] As a further improvement to the above scheme, the outer end of the plunger 6 is threaded to the cover plate 9; the plunger 6 is fixed inside the cylinder tube 3 by the cover plate 9.

[0017] As a further improvement to the above scheme, the core rod 7 is provided with scale lines to indicate the remaining amount of fly ash in the tank 1, and the air passage in the core rod 7 extends to the end.

[0018] The working principle of a fly ash silo level gauge is as follows: fly ash is continuously fed into the silo 1 for storage. As the amount of fly ash changes, the core rod 7 slides upward. As the amount of fly ash increases, the top surface of the fly ash changes upward. The rise of the top surface of the fly ash drives the air bag 8 to move upward. At the same time, the air bag 8 drives the core rod 7 to slide upward in the plunger 6 until the silo 1 is full of fly ash.

[0019] When there is stored fly ash in tank 1, and it needs to be discharged by opening valve 5, the core rod 7 slides down. The weight of the core rod 7 and the air bag 8, retaining ring 10 and air nozzle 11 connected to the core rod 7 causes the core rod 7 to slide down as the amount of fly ash decreases. The amount of fly ash stored in tank 1 can be read by the scale on the core rod 7.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
