[0002] In the production process of Qilong capsule (Chinese patent medicine mainly using Astragalus and Earthworm as raw materials), centrifuge is needed to separate liquid and solid residues in Earthworm solution, and the solid residues are discharged from the slag discharge pipe at the lower end of the centrifuge body. In the prior art, an electric valve is generally arranged between the slag discharge pipe and the inner cavity of the centrifuge, and a manually opened and closed stop valve is arranged below the slag discharge pipe. During use, the technician observes the slag discharge pipe at intervals, and when the slag discharge pipe is full of solid residues, the stop valve needs to be manually opened to discharge the waste slag.
[0003] The inventor attempts to arrange a light barrier type laser sensor on the slag discharge pipe and an electric stop valve at the lower end of the slag discharge pipe. When the slag discharge pipe is full, the laser sensor is triggered and transmits a signal to the controller to realize automatic slag discharge of the slag discharge pipe.
[0004] However, in the above technical solution, the laser emitting surface of the light barrier type laser sensor is prone to accumulate dirt, which affects the detection accuracy. In addition, the light barrier type laser sensor is prone to false measurement due to the dirt attached to the inner wall of the slag discharge pipe. SUMMARY
[0005] The utility model provides a centrifuge based on photoelectric monitoring and qilong capsule production line can solve at least one of the above technical problems.
[0006] To solve the above technical problems, one or more embodiments of the utility model provide a centrifuge based on photoelectric monitoring, which comprises a centrifuge body, and the centrifuge body has a transparent and vertical slag discharge pipe at the lower end. The slag discharge pipe comprises an inner tube and an outer tube, and the lower end of the inner tube penetrates the outer tube and is provided with a first electric stop valve. At least one rotating ring is sleeved on the outer circle of the inner tube, and the rotating ring is fixed to the inner wall of the outer tube and is located at the upper part of the slag discharge pipe. A light barrier type laser sensor is installed on the rotating ring, and the emitting part and the receiving part of the light barrier type laser sensor are symmetrical about the central axis of the rotating ring. The outer tube is connected with a driving assembly, and the driving assembly can drive the outer tube to rotate around the inner tube and be positioned.
[0007] The above one or more technical solutions have the following advantages:
[0008] The slag discharge pipe in the scheme comprises an inner pipe and an outer pipe, the lower end of the inner pipe penetrates through the outer pipe, and the lower end of the inner pipe is provided with a first electric stop valve. A rotating ring is sleeved on the outer circle of the inner pipe, the rotating ring is fixed to the inner wall of the outer pipe, and a pair of laser sensors are installed on the rotating ring. This arrangement facilitates the use of the outer pipe to protect the pair of laser sensors and reduces the probability of measurement error caused by dust accumulation on the laser incidence surface.
[0009] In addition, the outer pipe and the rotating ring in the scheme can rotate around the inner pipe under the driving of the driving assembly, which facilitates the adjustment of the laser path of the pair of laser sensors and avoids the case that the local position of the inner pipe is measured incorrectly due to the attachment of residues.

A pair of laser sensors are installed on the rotating ring, and the emitting part and the receiving part of the pair of laser sensors are symmetrical about the central axis of the rotating ring. The outer pipe 3 is connected with a driving assembly, and the driving assembly can drive the outer pipe 3 to rotate around the inner pipe 4 and position.
[0017] Specifically, a plurality of supporting legs 2 are installed at the lower part of the centrifuge body 1, and the plurality of supporting legs 2 support the centrifuge body 1 so that the centrifuge body 1 can be suspended.
[0018] Specifically, the laser emitter 1201 and the laser receiver 1202 are provided in the laser sensor, and the laser receiver 1202 sends a trigger signal to the controller when the laser receiver 1202 fails to receive the laser signal.
[0019] In the embodiment, the centrifuge body 1 has a separation cavity, and the outer wall of the separation cavity is formed by a screen cylinder. After the mixed liquid of earthworm is injected into the separation cavity of the centrifuge body 1, solid-liquid separation and screening can be realized by rotating the screen cylinder. The residue is sent from the bottom of the separation cavity to the residue discharge pipe, and the clear liquid without residue is discharged from the clear liquid discharge outlet.
[0020] Specifically, in order to realize the guidance when the outer tube 3 rotates, a mounting seat 7 is arranged at the bottom of the centrifuge body 1, and the mounting seat 7 is detachably fixed with the centrifuge body 1. More specifically, the upper end of the outer tube 3 has an annular flange, and the outer diameter of the flange is greater than the outer diameter of the outer tube 3. A stepped hole is arranged on the mounting seat 7, and the upper end of the stepped hole penetrates the mounting seat 7 upward. The stepped hole includes a first hole with a larger diameter and a second hole with a smaller diameter, and the flange is rotatably installed in the first hole, and the outer diameter of the flange is equal to the diameter of the first hole.
[0021] More specifically, the mounting seat 7, the inner tube 4 and the central axis of the outer tube 3 are arranged coaxially.
[0022] In the embodiment, the upper part of the outer tube 3 is connected with a driving assembly, and the driving assembly is supported by the centrifuge body 1. Specifically, the driving assembly includes a motor, the output shaft of the motor is coaxially fixed with a gear 9, and the outer ring of the outer tube 3 is coaxially fixed with an annular gear ring 6, and the gear 9 is engaged with the gear ring 6. Specifically, the motor is fixedly installed at the bottom wall of the centrifuge, and the output shaft of the motor is vertically downward and fixed with the gear 9. In some other structure, the motor here can also be replaced by a pneumatic motor.
[0023] In the embodiment, the outer tube 3 includes a first half-annular tube and a second half-annular tube which are spliced with each other.

[0025] In the embodiment, the upper part and the lower part of the outer tube 3 are respectively provided with a rotating ring.
[0026] Specifically, the upper part of the outer tube 3 is provided with a first rotating ring 11, and the lower part of the outer tube 3 is provided with a second rotating ring 10. The first rotating ring 11 is provided with a first pair of laser sensors, and the second rotating ring 10 is provided with a second pair of laser sensors. The first rotating ring 11 and the first pair of laser sensors can detect whether the inner tube 4 is full of waste residues, and whether the first electric stop valve 5 at the lower end of the inner tube 4 needs to be opened to discharge excess waste residues. The second rotating ring 10 and the second pair of laser sensors can detect whether the inner tube 4 is substantially full of waste residues, and whether the first electric stop valve 5 at the lower end of the inner tube 4 needs to be closed to facilitate subsequent storage of waste residues.

When the first pair of laser sensors on the first rotating ring 11 are triggered, the first rotating ring 11 drives the first pair of laser sensors to rotate around the inner tube 4. If the first pair of laser sensors are still triggered, the controller opens the first electric stop valve 5. When the second pair of laser sensors of the second rotating ring 10 are not triggered, it indicates that the residue discharge pipe is empty, and the controller closes the first electric stop valve 5.
