Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a powder collector blocking feedback device. Background Art

[0002] At present, after the pendulum mill grinds the block material into powder, the powder is transported out through the airflow generated by the fan, and then transported to the powder collector after being screened by the powder selector for qualified particle size products. The lower part of the powder collector is a cone to collect the finished powder, and then transported to the finished product tank by connecting the conveying equipment (commonly used as a screw conveyor), so that the powder becomes a commodity for sale. However, it is not easy to be discovered when the subsequent equipment at the lower part of the powder collector is congested. The lack of material in the finished product silo will cause the subsequent equipment to run idle, which is energy-consuming and ineffective; due to the congestion at the back end, the powder is piled up in the powder collector, resulting in a large amount of powder that cannot be deposited normally, and circulates in the entire system, causing elbows and other parts to be easily worn through, resulting in volume repair and loss; it will cause the powder to circulate in the system, causing the main fan and powder selector to run idle and consume energy, and the parts in contact with the material will be seriously eroded, with a short service life, a high frequency of replacement of accessories, and increased use costs. Therefore, a detection device is needed to monitor the lower end of the powder collector to prevent waste caused by idling of the equipment. Utility Model Content

Specific Embodiments

[0015] The following further explains the present utility model in conjunction with the drawings and specific embodiments.

[0016] Embodiment: As shown in the figure, a material blocking feedback device for a powder collector according to the present utility model includes a powder collector 1. The powder collector 1 includes a bracket 2, a housing 3, an air inlet 4, and a discharge port 5. The bracket 2 is fixed around the outer contour of the housing 3, and a gasket is further connected to the bottom end of the bracket 2. An air inlet 4 communicating with the inside of the housing 3 is provided at the upper end of the housing 3, and a discharge port 5 connected to an external conveying mechanism is provided at the lower end. A detection mechanism 6 is further provided inside the housing 3. The detection mechanism 6 is installed on the inner wall of the housing 3 near the discharge port 5. The detection mechanism 6 includes a housing 3. Inside the housing 3, there are a moving plate 7, a spring 8, a connecting plate 9, a vibrator 10, a support plate 11, a rotating seat 12, and a pressure sensor 13. The pressure sensor 13 is installed on the side wall of the housing 3, and its detection end is parallel to the surface of the housing 3. A rotating seat 12 is installed on another side wall of the housing 3, and a support plate 11 is connected to the rotating seat 12. The connecting plate 9 is installed in the middle of the bottom surface of the housing 3. A vibrator 10 is installed on one side of the connecting plate 9 close to the bottom surface, and a spring 8 is installed on the other side. The middle of the moving door is fixedly connected to the spring 8, and the upper end edge of the back surface of the moving door is fixedly connected to the support plate 11, and the lower end keeps a distance from the vibrator 10 under normal conditions.

[0017] A slot is opened in the middle of the connecting plate 9. The pressure sensor 13 is installed in the slot and its detection end faces the spring 8 and is fixedly connected to the spring 8. By connecting the pressure sensor 13 to an external drive, the pressure change transmitted at the movable plate 14 can be monitored in real time, so as to judge whether a blockage occurs inside the powder collector 1.

[0018] An active plate 14 adapted to the inner cavity is further provided on the housing 3. The active plate 14 is slidably connected to the housing 3. The active plate 14 is used to prevent the leakage of materials from the inner cavity of the housing 3, so as to avoid the failure of the spring 8 or pneumatic components.

[0019] The size of the moving plate 7 is smaller than the inner cavity size of the housing 3. When moving, it takes the support plate 11 as a fulcrum, approaches or moves away from the vibrator 10, makes a rotational motion, and simultaneously compresses the spring 8. The size of the active plate 14 is larger than that of the moving plate 7 and is located in front of the moving plate 7. It can be used as a baffle to evenly distribute the force on the active plate 14, and at the same time can prevent the leakage of materials to the outside.

[0020] The vibrator 10 is electrically connected to an external power supply through a wire. The operation and stop of the vibrator 10 can be controlled through the external power supply, which is convenient for vibrating the moving plate 7 to relieve slight blockages.

[0021] A detachable back plate 15 is further provided on the back of the housing 3. Through the detachable back plate 15, the back of the housing 3 can be opened and closed at any time. Since the front surface of the housing 3, that is, the surface of the moving plate 7, needs to be connected to the inner wall of the powder collector 1 for detection during installation, the installation of other components, circuit connection, and subsequent detection and maintenance need to be carried out from the back plate 15.

[0022] The utility model contacts the materials in the powder collector through a moving plate. When the materials accumulate, they will gradually squeeze the moving plate, causing the moving plate to rotate inward, so as to first squeeze the spring and then contact the vibrator. After the spring is stressed, it will transmit the pressure to the pressure sensor, and the early warning detection function can be realized through external control. When the early warning value is reached, the vibrator can be started to squeeze the movable plate at a high frequency, so as to dredge the slight blockage. Through this device, it is possible to prevent the continuous erosion of the elbow blades and other parts when the materials accumulate, resulting in wear, and at the same time, it is possible to avoid the idling of the equipment motor or the conveying equipment, saving energy and reducing emissions, and the structure is simple and easy to use.

[0023] The above is only used to illustrate the technical solution of the utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the utility model should be covered within the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
