Description

Technical Field

[0001] The utility model belongs to the technical field of liquid level meter production equipment and relates to a float ball detection device. Background Art

[0002] The float of the level gauge is a movable part mounted on the guide rod of the level gauge body. The float fluctuates with the liquid level. When the float is close to the reed switch inside the guide rod, it can trigger the reed switch to connect and realize liquid level monitoring. The float includes a float made of polymer material and a magnetic ring located on the inner ring of the float. When assembling the magnetic ring and the float, there are poor assembly conditions such as the misalignment of the magnetic ring. Therefore, before installing the float on the guide rod of the level gauge body, it is necessary to perform reliability testing on the float to ensure that it can trigger the reed switch normally after installation. At present, manual testing is mainly used, that is, the float is installed when the reed switch is in a conductive state, and the float limit joint is installed after confirming the trigger. This method limits the efficiency of float detection, and each level gauge body needs to be connected and disassembled, which is inefficient. Utility Model Content

[0003] The purpose of the utility model is to provide a float detection device in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to perform reliability detection on the float.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a float detection device, characterized in that it includes a frame, an operating platform, a material rack, a defective material receiving box and a good product discharge hopper, the material rack includes a mounting shaft fixed on the frame, a rotating wheel rotatably connected to the mounting shaft and a detection unit evenly distributed outside the rotating wheel in the circumference, the detection unit includes an insertion rod, a reed switch located inside the insertion rod, a power supply, a conductive contact, a conductive sheet and an electromagnetic adsorption block, the electromagnetic adsorption block is located outside the insertion rod, and the reed switch is located inside the insertion rod; the positive electrode of the power supply, the coil of the electromagnetic adsorption block, the reed switch, the conductive contact, the conductive sheet and the negative electrode of the power supply can form an electrical circuit.

[0005] Furthermore, the operating platform is provided with an avoidance groove, and the insertion rod can partially pass through the avoidance groove and extend above the operating platform.

[0006] Furthermore, the rotating wheel is driven to rotate by a motor.

[0007] During operation, the operator puts the float to be tested on the plug rod one by one. If the float is a good product, the float can trigger the two reeds of the reed switch to conduct. At this time, when the conductive contact is in contact with the conductive sheet, the electromagnetic adsorption block can be energized to form a magnetic field, and then adsorb the float with a magnetic ring. The float can maintain its state on the plug rod while the wheel is rotating until the conductive contact is separated from the conductive sheet. At this time, the circuit is disconnected, and the float can fall into the good product discharge hopper. On the contrary, if the float is a defective product, it cannot drive the two reeds of the reed switch to conduct, the coil in the electromagnetic adsorption block cannot be energized, and the float cannot be adsorbed by the electromagnetic adsorption block on the plug rod. The float can be separated from the plug rod when the wheel rotates to the plug rod tilted downward, and then fall into the defective material receiving box. This solution can ensure that the good float and the defective float fall from different positions, and then detect and select the float. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 and Figure 2 As shown, the float detection device includes a frame 1, an operating platform 2, a material rack, a defective material receiving box 3 and a good product discharge hopper 4, the material rack includes a mounting shaft 5 fixed on the frame 1, a rotating wheel 6 rotatably connected to the mounting shaft 5 and a detection unit uniformly distributed outside the rotating wheel 6 in the circumferential direction, the detection unit includes an insertion rod 7, a reed switch 8 located inside the insertion rod 7, a power supply 9, a conductive contact 10, a conductive sheet 11 and an electromagnetic adsorption block 12, the electromagnetic adsorption block 12 is located outside the insertion rod 7, and the reed switch 8 is located inside the insertion rod 7; the positive electrode of the power supply 9, the coil of the electromagnetic adsorption block 12, the reed switch 8, the conductive contact 10, the conductive sheet 11 and the negative electrode of the power supply 9 can form an electrical circuit.

[0013] The operating platform 2 is provided with an avoidance groove, and the insertion rod 7 can partially pass through the avoidance groove and extend above the operating platform 2 . The rotating wheel 6 is driven to rotate by a motor 13 .

[0014] The power source 9 can be shared by multiple monitoring units. Since the wheel 6 is a rotating part, a brush structure can be used between the power source 9 and its power connection point.

[0015] During operation, the operator sets the float to be tested on the plug rod 7 one by one. If the float is a good product, the float can trigger the two reeds of the reed switch 8 to conduct. At this time, when the conductive contact 10 is in contact with the conductive sheet 11, the electromagnetic adsorption block 12 can be energized to form a magnetic field, thereby adsorbing the float with a magnetic ring. The float can maintain the state on the plug rod 7 when the rotary wheel 6 rotates until the conductive contact 10 is separated from the conductive sheet 11. At this time, the circuit is disconnected, and the float can fall into the good product discharge hopper 4. On the contrary, if the float is a defective product, it cannot drive the two reeds of the reed switch 8 to conduct, the coil in the electromagnetic adsorption block 12 cannot be energized, and the float cannot be adsorbed by the electromagnetic adsorption block 12 on the plug rod 7. The float can be separated from the plug rod 7 when the rotary wheel 6 rotates to the plug rod 7 tilted downward, and then fall into the defective receiving box 3. This solution can ensure that the good float and the defective float fall from different positions, thereby detecting and selecting the float.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
