Description

Technical Field

[0001] This utility model relates to the field of ash storage bin unloading technology, specifically to an ash storage bin unloading dust removal device. Background Technology

[0002] In industrial production, especially in areas involving the storage and transportation of ash materials, such as cement plants and power plants, ash storage silos are essential equipment. However, the process of discharging ash materials from ash storage silos often generates a large amount of dust, polluting the environment, which not only affects the health of operators but may also lead to equipment damage or reduced efficiency.

[0003] Traditional dust removal methods mainly include simple bag filters or local dust collection devices. These methods are often ineffective in controlling dust, especially when the material is discharged at high flow rates.

[0004] To overcome the above problems, a high-efficiency dust removal device was designed specifically for the material unloading process of ash storage silos. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a dust removal device for ash storage bins.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a dust removal device for ash storage bins, comprising an ash storage bin body, a screw conveyor, a dust removal mechanism, and a feeding mechanism;

[0007] The feeding mechanism is located after the discharge port of the ash storage silo, and transfers the ash material into the screw conveyor.

[0008] The dust removal mechanism includes a vacuum cleaner and a ring mechanism. The ring mechanisms are arranged in a pair of mirror images, and the two ring mechanisms are arranged around the storage and discharge port after being close to each other. Each of the two ring mechanisms is provided with a vacuum port connected to the vacuum cleaner.

[0009] As an improvement, the feeding mechanism includes a support base, an adjustment mechanism, and a feeding pipe;

[0010] After the adjustment mechanism is set on the support base, push one end of the feeding pipe to be close to the main discharge port of the ash storage silo, and the other end to be close to the feed port of the screw conveyor.

[0011] As an improvement, the adjustment mechanism includes a hydraulic telescopic rod and a rotary motor;

[0012] After the hydraulic telescopic rod is fixed to the top surface of the support base, the other end is rotatably connected to the discharge pipe via a rotating rod. The tilt angle of the discharge pipe is adjusted by a rotating motor fixed on the hydraulic telescopic rod to reduce the risk of dust overflow.

[0013] As an improvement, the ring mechanism includes a movable support and a ring plate;

[0014] The mobile support is equipped with casters. With the help of the casters, the mobile support moves to be close to the main body of the ash storage bin. The annular plate is fixedly installed on the top of the mobile support, and the bottom surface of the annular plate is evenly provided with dust suction ports. Each dust suction port is connected to the connecting pipe located on the top surface of the annular plate. The vacuum cleaner performs dust suction by connecting to the connecting pipe of the two annular mechanisms.

[0015] As an improvement, the dust removal mechanism also includes a sprayer and a ring-shaped water pipe;

[0016] After the annular water pipe is fixed to the top surface of each annular plate, it is connected to the sprayer located on the side wall of the annular plate, and multiple sprayers are evenly arranged along the edge.

[0017] As an improvement, a windshield is also included, which is fixed to the bottom of each ring plate to block dust and water mist.

[0018] The advantages of this utility model compared with the prior art are as follows:

[0019] 1. By setting up a pair of mirror ring mechanisms around the discharge port of the ash storage hopper, and evenly distributing multiple dust suction ports on them, it is ensured that dust generated in all directions during the material feeding process can be effectively captured.

[0020] 2. Assisted dust suppression with spraying: The design of the sprayer and ring water pipe can spray fine water droplets into the air while vacuuming, further enhancing the dust suppression effect;

[0021] 3. The adjustment mechanism, consisting of a hydraulic telescopic rod and a rotary motor, can flexibly adjust the angle and position of the feeding pipe according to actual needs, ensuring that the optimal working condition is maintained regardless of the amount of ash or the feeding speed.
