Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder storage technology, and in particular to a moisture-proof storage tank for fly ash. Background Technology
[0002] Fly ash is a fine ash collected from the flue gas after coal combustion and is a major solid waste discharged from coal-fired power plants. It is formed by the combustion and cooling of pulverized coal at high temperatures (1300-1500℃). Most of it is spherical with a smooth surface and small micropores; some particles are agglomerated during melting, resulting in a rough surface and many honeycomb-like particle structures.
[0003] During storage, fly ash may accumulate excessive moisture in the container due to prolonged storage, leading to clumping and even difficulties in discharging. Utility Model Content
[0004] The purpose of this utility model is to address the existing problems by providing a moisture-proof storage tank for fly ash.
[0005] This utility model is achieved through the following technical solution: a fly ash moisture-proof storage tank, including a tank body, a support frame is provided on the outside of the tank body, a pipe is spirally arranged on the inner wall of the tank body, a rotating rod is arranged in the loop of the pipe, stirring rods are evenly distributed on the rotating rod, the rotating rod is connected to the output shaft of a motor, the motor is installed on the tank cover, the tank cover is located at the upper port of the tank body, a discharge pipe is provided at the lower end of the tank body, and a discharge valve is provided on the discharge pipe.
[0006] As a further improvement to the above solution, an exhaust valve is provided at the upper end of the pipe, a hot air blower is connected to the lower end of the pipe, and the hot air pipe is installed on the support frame.
[0007] The hot air ejected from the hot air blower enters the spiral-shaped pipe to increase the temperature inside the tank, causing the fly ash inside the tank to lose moisture and prevent it from clumping together. After losing heat, the hot air inside the pipe is discharged from the exhaust valve on the pipe.
[0008] As a further improvement to the above solution, the discharge valve includes a valve ball, which is disposed inside the discharge pipe. The two sides of the valve ball are rotatably connected to the side frame via a rotating shaft. The side frame is connected to the outer wall of the discharge pipe. One end of the rotating shaft has a ring handle. A stop bar is provided on the side of the ring handle near the side frame. A limiting rod is provided circumferentially on one side frame near the ring handle. A discharge channel is provided through the valve ball.
[0009] Rotating the ring handle drives the shaft to rotate together, and the valve ball also rotates, so that the through hole inside the valve ball coincides with or forms an angle with the axis of the discharge pipe. If they coincide, the material is discharged; if they form an angle, the discharge channel is closed. In addition, the stop bar on the ring handle is limited by the limit bar to reciprocate within a range of less than 90°.
[0010] As a further improvement to the above solution, a material injection pipe is provided through the upper part of the tank, a blockage plate is provided on the material injection pipe, the blockage plate is connected to the shaft, one end of the shaft is connected to the motor output shaft, and the motor is installed on the outer wall of the material injection pipe.
[0011] Fly ash is added into the tank through the injection pipe for storage. During the storage process, the plug plate in the injection pipe and the valve ball on the discharge pipe seal the tank to prevent external moisture from entering the tank.
[0012] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. It uses a hot air blower to deliver hot air into the pipeline to increase the temperature inside the tank, thereby heating the fly ash inside the tank to dry the fly ash, remove moisture, and prevent the fly ash from clumping together. At the same time, the stirring rod is driven by a motor to rotate, so as to facilitate the smooth discharge of fly ash. The tank body is sealed by the plug plate on the injection pipe and the valve ball on the discharge pipe to prevent moisture. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figures 1 to 3 As shown, a fly ash moisture-proof storage tank includes a tank body 1, a support frame 14 is provided on the outside of the tank body 1, a pipe 2 is spirally arranged on the inner wall of the tank body 1, a rotating rod 6 is arranged in the ring of the pipe 2, stirring rods 7 are evenly distributed on the rotating rod 6, the rotating rod 6 is connected to the output shaft of the motor 5, the motor 5 is installed on the tank cover 4, the tank cover 4 is located at the upper port of the tank body 1, a discharge pipe 8 is provided at the lower end of the tank body 1, and a discharge valve 9 is provided on the discharge pipe 8.
[0018] As a further improvement to the above solution, an exhaust valve 13 is provided at the upper end of the pipe 2, and a hot air blower 3 is connected to the lower end of the pipe 2. The hot air pipe is installed on the support frame 14.
[0019] The hot air ejected by the hot air blower 3 enters the spirally arranged pipe 2 to increase the temperature inside the tank 1, causing the fly ash inside the tank 1 to lose moisture and prevent it from clumping together. After losing heat, the hot air in the pipe 2 is discharged from the exhaust valve 13 on the pipe 2.
[0020] As a further improvement to the above solution, the discharge valve 9 includes a valve ball 91, which is disposed inside the discharge pipe 8. The two sides of the valve ball 91 are rotatably connected to the side frame 93 via a rotating shaft 94. The side frame 93 is connected to the outer wall of the discharge pipe 8. One end of the rotating shaft 94 has a ring handle 95. A stop bar 96 is provided on the side of the ring handle 95 near the side frame 93. A limiting rod 97 is provided circumferentially on one side frame 93 near the ring handle 95. A discharge channel 92 is provided through the valve ball 91.
[0021] Rotating the ring handle 95 drives the rotating shaft 94 to rotate together, and at the same time the valve ball 91 also rotates, so that the discharge channel 92 inside the valve ball 91 coincides with or forms an angle with the axis of the discharge pipe 8. If they coincide, discharge is carried out; if they form an angle, the discharge channel 92 is closed. In addition, the stop bar 96 on the ring handle 95 is restricted by the limit bar 97 to reciprocate within a range of less than 90°.
[0022] As a further improvement to the above scheme, a material injection pipe 7 is provided through the upper part of the tank body 1, and a blockage plate 12 is provided on the material injection pipe 7. The blockage plate 12 is connected to the shaft 11, and one end of the shaft 11 is connected to the output shaft of the motor 10. The motor 10 is installed on the outer wall of the material injection pipe 7.
[0023] Fly ash is added into tank 1 through injection pipe 7 for storage. During the storage process, the blockage plate 12 in injection pipe 7 and the valve ball 91 on discharge pipe 8 seal tank 1 to prevent external moisture from entering tank 1.
[0024] The working principle of a fly ash moisture-proof storage tank: Fly ash is added into the tank through the injection pipe 7. Before adding the fly ash, the motor 10 is activated to drive the blocking plate 12 to rotate, so that the injection pipe 7 is unobstructed. After the fly ash in the tank 1 is full, the fly ash in the tank 1 is heated periodically to remove moisture. In addition, the stirring rod 7 is driven by the motor 5 to rotate, so that the fly ash in the tank 1 is turned over, preventing the fly ash from clumping together in the tank 1.
[0025] 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.
