Description

Technical Field

[0001] This utility model relates to the field of cement testing instruments, and in particular to a rotary paddle level gauge. Background Technology

[0002] Currently, the clinker tent warehouse central warehouse stores clinker used in cement production. Unlike cement, which is a powdery material, and unlike gravel, which is a blocky material, clinker has both block and surface material properties. The block size ranges from 1mm to 90mm and is irregular in shape.

[0003] The level gauge used for silo full detection is a rotary paddle level gauge, such as... Figure 1 As shown, it includes a drive motor, rotating blades, and a rotating rod 10 cm long. During use, when the material reaches the rotating blades, clinker blocks will get stuck between the rotating blades and the silo wall, preventing the rotating blades from rotating normally. Even when the silo is empty, a full alarm will be displayed, the level gauge will not function, and the clinker unloading efficiency will be low.

[0004] On-site attempts to lengthen the rotating rod did solve the material jamming problem, but when the material in the silo was higher than the rotating blades of the rotary level gauge, the material in the silo would move downwards simultaneously when the material was discharged from the bottom of the silo. Meanwhile, the rotating blades and rod installed inside the silo remained stationary. The downward force of the material would cause the rotating rod to bend and undergo irreversible bending deformation, resulting in damage and failure of the rotary level gauge. Utility Model Content

[0005] The purpose of this invention is to provide a rotary paddle level gauge that is reliable in operation and avoids material jamming.

[0006] This utility model is implemented by the following technical solution: a rotary paddle level gauge, which includes a drive motor, a connecting shaft, a flexible component, and a buckle; one end of the flexible component is inserted and fixed to one end of the connecting shaft, and the other end of the connecting shaft is coaxially connected to the output shaft of the drive motor; the other end of the flexible component is curled into a loop and fixed by the buckle.

[0007] Furthermore, the flexible component is a steel wire rope.

[0008] Furthermore, the buckle includes a U-bolt, a retainer, and a locking nut; the U-bolt passes through the retainer, and the locking nut is screwed onto the end of the U-bolt.

[0009] Furthermore, a connecting plate is fitted and fixed onto the output shaft of the drive motor.

[0010] The advantages of this invention are as follows: By removing the rotating blade and rotating rod and replacing them with a steel wire rope, and weaving a loop at the end of the steel wire rope to replace the rotating blade, even if large pieces of material are stuck when the material in the silo is below the rotating blade, the drive motor will still have normal rotational force, and the steel wire rope and the loop at its end will undergo slight deformation, causing the large pieces of material to fall off instantly. The rotary paddle level gauge will also work normally. The steel wire rope is a flexible rod. When the material in the silo is higher than the detection position, the steel wire rope will bend due to the accumulation of material. When the material is unloaded, the steel wire rope will return to its original state without affecting its use, ensuring normal and reliable operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "front", "rear", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 2 to 4 As shown, this embodiment provides a rotary paddle level gauge, which includes a drive motor 1, a connecting shaft 2, a flexible component 3, and a buckle 4. In this embodiment, the flexible component 3 is made of steel wire rope. A connecting plate 5 is fixedly mounted on the output shaft of the drive motor 1. A sleeve is fixed to the edge of the hole on the connecting plate 5 for mounting the output shaft of the drive motor 1. The sleeve is fixed to the output shaft of the drive motor 1 by screws. In use, the connecting plate 5 is fixed to the outside of the silo wall by bolts.

[0020] One end of the wire rope is threaded and fixed to one end of the connecting shaft 2. The other end of the connecting shaft 2 is coaxially connected to the output shaft of the drive motor 1. The drive motor 1 drives the connecting shaft 2 and the wire rope to rotate synchronously. The other end of the wire rope is coiled into a loop and fixed by a buckle 4. The buckle 4 includes a U-bolt 4.1, a retainer 4.2, and a locking nut 4.3. The U-bolt 4.1 is threaded onto the retainer 4.2, and the end of the U-bolt 4.1 is fitted with a screw-on locking nut 4.3. The coiled end of the wire rope and the middle of the wire rope are fitted into the U-bolt 4.1 and locked by the locking nut 4.3.

[0021] In this embodiment, the rotating blade and rotating rod are removed and replaced with a steel wire rope. A loop is woven at the end of the steel wire rope to replace the rotating blade. Using this method, when the material in the silo is lower than the rotating blade, even if large pieces of material are stuck, the drive motor 1 will have normal rotational force, and the steel wire rope and the loop at its end will deform slightly, causing the large pieces of material to fall off instantly. The rotary paddle level gauge will also work normally. The steel wire rope is a flexible rod. When the material in the silo is higher than the detection position, the steel wire rope will bend due to the accumulation of material. When the material is unloaded, the steel wire rope returns to its original state without affecting its use, and it can operate normally and reliably.

[0022] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
