Description

Technical Field

[0001] The utility model relates to the field of open disc feeders, in particular to an open disc feeder for cement manufacturing with controllable feeding. Background Art

[0002] The feeder consists of a rotatable disc, a guide sleeve and a scraper. The material in the silo is accumulated on the disc with a wear-resistant lining through the guide sleeve. The disc rotates and the material is scraped out by the scraper for feeding. The feed amount can be changed by adjusting the position of the scraper or the height of the guide sleeve. The disc diameter is generally less than 3 meters and the speed does not exceed 10 rpm. The disc feeder runs smoothly and reliably, the feed amount is easy to adjust, and the energy consumption is low, but the structure is relatively bulky and is suitable for powdery and granular materials with less viscosity.

[0003] The Chinese patent with publication number CN203392474U discloses a feeder, and particularly relates to an open disc feeder for cement manufacturing, which is used for mixing and feeding cement raw materials. It includes a disc frame, the upper part of which is provided with a movable sleeve and a channel steel column, the movable sleeve is movable through the channel steel column, the movable sleeve is provided with a feed pipe that is movably contacted with the movable sleeve, the disc frame is provided with a rotating channel, the disc frame is provided with a rotating disc, and the disc frame is provided with a drop port connected to the rotating channel. The open disc feeder for cement manufacturing has a compact structure, is easy to operate, and ensures work efficiency.

[0004] When the feeder of the above patent discharges materials, the discharge speed can only be controlled by adjusting the extension length of the scraper inside the feeder. However, if the material is powdery or highly viscous, when the material near the edge of the feeder falls, it may adhere to the rear end material and fall together, resulting in too much material being discharged at one time. Utility Model Content

[0005] The purpose of the utility model is to provide an open disc feeder for cement manufacturing with controllable feeding.

A single-chip microcomputer structure is arranged on the rotating motor, and the single-chip microcomputer structure is electrically connected to the weighing sensor. When the material falls from the feeding port of the feeder onto the receiving plate, the weight of the receiving plate changes and is detected by the weighing sensor. If the material dropped at one time exceeds the preset threshold of the weighing sensor, the weighing sensor sends a signal to the single-chip microcomputer structure, and the single-chip microcomputer structure controls the rotating motor to stop rotating, thereby stopping the feeder or slowing down the feeding speed, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an open disc feeder for cement manufacturing with controllable feeding, comprising a ground-contacting base, a rotating motor is arranged on the ground-contacting base, a single-chip microcomputer structure is arranged on the rotating motor, and also comprising a fixed base, the fixed base is arranged on one side of the ground-contacting base, a feeder is arranged on the fixed base, a reset telescopic rod is arranged around the feeder, a mounting base is arranged on the end of the reset telescopic rod away from the fixed base, a weighing sensor is arranged on the mounting base, a material receiving plate is arranged on the weighing sensor, and a side baffle is arranged on the material receiving plate.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In order to solve the problem that in the prior art, the feeding speed of the feeder can only be controlled by adjusting the extension length of the scraper in the feeder, but if the material is powdery or highly viscous, the material near the edge of the feeder may be attached to the rear material when it falls, resulting in too much material being discharged at one time, this embodiment provides the following technical solutions:

[0020] An open disc feeder for cement manufacturing with controllable feeding comprises a ground contact base 1, a rotating motor 2 is arranged on the ground contact base 1, a single chip microcomputer structure 3 is arranged on the rotating motor 2, and a fixed base 7 is arranged on one side of the ground contact base 1, a feeder 14 is arranged on the fixed base 7, a reset telescopic rod 8 is arranged around the feeder 14, a mounting base 9 is arranged on the end of the reset telescopic rod 8 away from the fixed base 7, a weighing sensor 10 is arranged on the mounting base 9, a material receiving plate 11 is arranged on the weighing sensor 10, and a material receiving plate 11 is arranged on the material receiving plate 11. A side baffle 12 is provided, and a discharge port 13 is opened on the side baffle 12, and the discharge port 13 and the side baffle 12 are integrally arranged. A rotating connecting shaft 4 is provided on the output end of the rotating motor 2, and the rotating connecting shaft 4 is bolted to the output end of the rotating motor 2. A stabilizing block 5 is provided on the end of the rotating connecting shaft 4 away from the rotating motor 2, and the stabilizing block 5 is in contact with the rotating bearing of the rotating connecting shaft 4. A transmission shaft 6 is provided on the end of the stabilizing block 5 away from the rotating connecting shaft 4, and the transmission shaft 6 is bolted to the rotating connecting shaft 4, and the transmission shaft 6 is connected to the feeder 14 through gear transmission;

[0021] In this embodiment, when the user starts the rotating motor 2 and the rotating motor 2 starts to drive the feeder 14 to discharge materials, a circle of receiving plates 11 are arranged at the lower end of the discharge port of the feeder 14, and a JLBU-1 weighing sensor 10 is arranged at the lower end of the receiving plate 11. A single-chip microcomputer structure 3 is arranged on the rotating motor 2, and the single-chip microcomputer structure 3 is electrically connected to the weighing sensor 10. When the material falls from the discharge port of the feeder 14 onto the receiving plate 11, the weight of the receiving plate 11 changes and is detected by the weighing sensor 10. If the material dropped at one time exceeds the weight of the weighing sensor 10, When the preset threshold is reached, the weighing sensor 10 sends a signal to the single-chip structure 3, and the single-chip structure 3 controls the rotating motor 2 to stop or slow down the rotation, thereby stopping or slowing down the feeding speed of the feeder. Because the receiving plate 11 is set with an arc, and the lowest point of the arc is at the discharge port 13, the material will fall from the discharge port 13 along the receiving plate 11, and the reset telescopic rod 8, which was originally pressed down by the material at the lower end, is lifted up again by the internal spring, so that the receiving plate 11 is closer to the feeding port of the feeder 14, to avoid the material falling on the receiving plate 11 and bouncing up due to the large height difference;

[0022] In this embodiment, an electronic display screen 15 is provided on the ground contact base 1, and the electronic display screen 15 is electrically connected to the weighing sensor 10;

[0023] Working principle: When the user starts the rotating motor 2 and the rotating motor 2 starts to drive the feeder 14 to discharge materials, a circle of receiving plates 11 are arranged at the lower end of the discharge port of the feeder 14, and a JLBU-1 weighing sensor 10 is arranged at the lower end of the receiving plate 11. A single-chip microcomputer structure 3 is arranged on the rotating motor 2, and the single-chip microcomputer structure 3 is electrically connected to the weighing sensor 10. When the material falls from the discharge port of the feeder 14 onto the receiving plate 11, the weight change of the receiving plate 11 is detected by the weighing sensor 10. If the material dropped at one time exceeds the preset threshold of the weighing sensor 10, the weighing sensor 10 sends a signal to the single-chip microcomputer structure 3. The single chip microcomputer structure 3 controls the rotating motor 2 to stop or slow down the rotation, thereby stopping or slowing down the feeding speed of the feeder. Since the receiving plate 11 is arranged with an arc, and the lowest point of the arc is at the discharge port 13, the material will fall from the discharge port 13 along the receiving plate 11, and the reset telescopic rod 8 whose lower end was originally pressed down by the material is lifted up again by the internal spring, so that the receiving plate 11 is closer to the discharge port position of the feeder 14, avoiding the material falling on the receiving plate 11 and bouncing up due to excessive height difference, and the weighing sensor 10 is connected to the electronic display screen 15, and the weight of the material on the receiving plate 11 will be displayed on the electronic display screen 15 in real time.
