Description

Technical Field

[0001] The utility model relates to the technical field of flat-plate centrifuges, in particular to a lighting mechanism for centrifuges. Background Art

[0002] Plate centrifuges are widely used in the pharmaceutical and chemical industries to separate solid substances from liquids. Plate centrifuges are mainly composed of a casing, a drum in the casing, a driving mechanism, a liquid skimming mechanism, and a scraping mechanism. After the solid-liquid mixture enters the drum through the feed port, the driving mechanism drives the drum to rotate to generate centrifugal force, so that the liquid part of the solid-liquid mixture enters the space between the casing and the drum through the filter holes on the side wall of the drum, and then is transmitted to the liquid storage tank outside the casing through the liquid outlet at the bottom of the casing, while the solid matter part is retained in the drum, thereby achieving solid-liquid separation.

[0003] In order to better observe the working state of the flat centrifuge, an observation window is usually set on the centrifuge cover, and a lighting mechanism is set inside the observation window. However, there are the following problems: the existing lighting mechanism is a fixed structure and cannot produce relative displacement with the cover, which is not conducive to clear observation. Utility Model Content

[0004] The utility model aims to provide a centrifuge lighting mechanism with reasonable structure and reliable use, so as to solve the problem that the fixed structure of the existing lighting mechanism cannot be moved, and is more conducive to observing the working state in the centrifuge.

[0005] The technical solution of the utility model is:

[0006] A lighting mechanism for a centrifuge comprises an observation window and a lighting lamp ring, and its technical key points are: the observation window is composed of an inclined guide cylinder fixed on a centrifuge cover, a flange plate arranged at the upper end of the inclined guide cylinder, a pressure cover connected to the flange plate, and a transparent window body arranged in the middle of the pressure cover; a slide groove is arranged on the inner wall of the inclined guide cylinder along its length direction; the number of the slide grooves is multiple and a slide bar is arranged in the slide groove; a clamping groove is arranged at the lower end of the slide bar; the lighting lamp ring is clamped and fixed by the clamping grooves of each slide bar; the upper end of each slide bar passes through the pressure cover and is connected and fixed by a positioning ring; a guide sleeve corresponding to the slide bar is arranged on the pressure cover, and a sealing gasket is arranged on the upper end surface of the guide sleeve.

[0007] In the above-mentioned centrifuge lighting mechanism, each chute is evenly arranged around the center line of the inclined guide cylinder.

[0008] In the above-mentioned centrifuge lighting mechanism, the inner peripheral surface of the positioning ring is welded and fixed to each sliding rod.

[0009] The beneficial effects of the utility model are:

[0010] The lighting ring is fixed by the slots at the lower ends of the slide bars. When the positioning ring is pushed or pulled, the position of the lighting ring in the oblique guide cylinder can be changed, thereby solving the problem that the fixed structure of the existing lighting mechanism cannot be moved, and making it more convenient to observe the working state in the centrifuge. In order to prevent the lighting ring from affecting the operation of other mechanisms in the casing, the positioning ring is pulled to completely retract the lighting ring into the oblique guide cylinder.

[0014] In the figure: 1. machine cover, 2. positioning ring, 3. sliding rod, 4. sealing gasket, 5. pressure cover, 6. flange, 7. oblique guide cylinder, 8. slide groove, 9. clamping groove, 10. lighting lamp ring, 11. transparent window body. DETAILED DESCRIPTION

[0015] The utility model is described in detail according to the accompanying drawings of the specification.

[0016] like Figure 1 to Figure 3 As shown, the lighting mechanism for the centrifuge includes an observation window and a lighting lamp ring 10.

[0017] The observation window is composed of an inclined guide cylinder 7 fixed on the centrifuge cover 1, a flange 6 arranged at the upper end of the inclined guide cylinder 7, a gland 5 connected to the flange 6, and a transparent window body 11 arranged in the middle of the gland 5. A slide groove 8 is arranged on the inner wall of the inclined guide cylinder 7 along its length direction. There are multiple slide grooves 8 and a slide bar 3 is arranged in the slide groove 8. A clamping groove 9 is arranged at the lower end of the slide bar 3. The lighting lamp ring 10 is clamped and fixed by the clamping groove 9 of each slide bar 3. The upper end of each slide bar 3 passes through the gland 5 and is connected and fixed by a positioning ring 2. A guide sleeve corresponding to the slide bar 3 is arranged on the gland 5, and a sealing gasket 4 is arranged on the upper end surface of the guide sleeve.

[0018] In this embodiment, each slide groove 8 is evenly arranged around the center line of the inclined guide cylinder 7. The inner circumference of the positioning ring 2 is welded and fixed to each slide rod 3.

[0019] Working principle:

[0020] The lighting lamp ring 10 is fixedly connected by the card slot 9 at the lower end of each slide rod 3. When the positioning ring 2 is pushed and pulled, the position of the lighting lamp ring 10 in the inclined guide tube 7 can be changed. In order to prevent the lighting lamp ring 10 from affecting the operation of other mechanisms in the casing, the positioning ring 2 is pulled to make the lighting lamp ring 10 completely retract into the inclined guide tube 7.

[0021] For centrifuges of different types and sizes, the utility model can also adjust the depth of the lighting lamp ring 10 into the casing according to the needs. It is applicable to a wide range and flexible to use.
