Description

Technical Field

[0001] This invention belongs to the field of physical separation technology, specifically relating to a rotary drum for destaining stained glass slides and a centrifuge based on the rotary drum. Background Technology

[0002] Natural drying of stained glass slides is inefficient, and dye droplets tend to adhere to the edges, causing uneven coloring. Even with drying equipment, the drying process can only be accelerated, not eliminated, as it does not eliminate pigment deposition at the slide edges. Therefore, current glass slide staining processes are not yet mature, and a technology is needed to address the problems of dye deposition at the slide edges affecting the overall color and low drying efficiency.

[0003] To address the issue of residual dye droplets at the edges of glass slides, centrifugation is considered as a method to eliminate them. However, conventional centrifuges are not suitable for stained glass slides and can easily damage them. Therefore, a special rotating drum is needed to centrifuge stained glass slides to eliminate residual dye droplets at the edges of the slides. Summary of the Invention

A slot is formed between two adjacent positioning posts, and a glass slide positioning frame is provided in the slot. A downwardly extending sleeve is connected to the center of the base plate, and a connection hole adapted to the centrifuge drive shaft is opened at the center of the sleeve.

[0006] As a preferred embodiment, a support plate is provided in any of the slots. The support plate is a flat plate and is perpendicular to the bottom plate. The two sides of the support plate are close to the inner wall of the inner cylinder and are fixedly connected to the adjacent positioning columns respectively. A large number of filter holes are provided on the support plate.

[0007] As a preferred embodiment, an outer cylinder is also provided outside the inner cylinder. The outer cylinder is generally in the shape of a cone with a larger top and a smaller bottom. The lower end of the outer cylinder is fixedly and sealed to the lower end of the inner cylinder or the outer edge of the bottom plate. The upper end of the outer cylinder is lower than the upper end of the inner cylinder. An outwardly extending baffle is connected to the outer edge of the upper end of the inner cylinder. The outer edge of the baffle extends beyond the outer cylinder. There is an annular gap between the baffle and the top of the outer cylinder. The baffle is used to block the splashing of liquid thrown outward along the inner wall of the outer cylinder and guide the liquid to flow out of the outer cylinder.

[0008] As a preferred embodiment, the slide positioning frame includes a rectangular frame with an insertion end and a positioning end at opposite ends. The positioning end is connected to two parallel positioning plates. Each positioning plate has a positioning slot on the side facing the insertion end. Each positioning plate has multiple positioning slots arranged sequentially along its length. The top and bottom of the rectangular frame are respectively provided with limiting plates parallel to the positioning plates. The opposing sides of the two limiting plates are inserted into the rectangular frame. The opposing surfaces of the two limiting plates are respectively provided with limiting slots that correspond one-to-one with the positioning slots. The slide is inserted into the rectangular frame from the insertion end and engages with the corresponding positioning slot and limiting slot.

[0009] A further technical problem to be solved by the present invention is to provide a centrifuge that solves the technical problem that conventional centrifuges cannot be used for destaining stained glass slides.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a centrifuge, including a base, a drive mechanism fixedly connected to the base, a drum connected to the end of the drive shaft of the drive mechanism, and a cover, wherein the cover is connected to the upper surface of the base and covers the drum, characterized in that the drum is the drum for descaling stained slides as described in any one of claims 1 to 4, an annular flow channel is formed between the cover and the drum, and a drain pipe communicating with the annular flow channel is provided on the base.

[0011] As a preferred embodiment, an air inlet pipe is connected to the top of the housing, the air inlet pipe is connected to the inside of the housing, and the outer end of the air inlet pipe is used to connect to a hot air blower.

[0012] As a preferred embodiment, the air inlet pipe is slidably connected to the cover, and a lifting driver is connected to the cover to drive the air inlet pipe to rise and fall. A cover is connected to the outer edge of one end of the air inlet pipe inside the cover. The lower end of the cover is directly opposite the upper end of the drum. A sealing ring is provided at the lower end of the cover. When the cover is lowered, it seals and connects with the top of the drum.

[0013] As a preferred embodiment, the drive mechanism is a direct-drive motor.

[0014] The beneficial effects of this invention are: by setting a slot and a slide positioning frame inside the drum, the slide is secured to the positioning frame and the positioning frame is secured to the slot, thus eliminating the problem of slides colliding with each other and breaking during the rotation of the drum, and achieving the technical goal of removing liquid from stained slides by the drum.

[0015] The present invention further enables the centrifuge to remove liquid from stained slides by placing the aforementioned drum inside the centrifuge, and further provides an air inlet pipe to introduce hot air into the centrifuge to dry the stained slides after liquid removal. This achieves the technical goal of one-step liquid removal and drying, eliminates the risk of contamination of the slides during the transfer process after liquid removal, improves the staining effect of the stained slides, and ensures the staining quality.

[0017] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Example 1

[0018] like Figure 1 The drum shown for destaining stained slides includes a disc-shaped base plate 1 with a flat upper surface. An upwardly extending inner cylinder 2 is connected to the outer edge of the base plate 1. The inner cylinder 2 is covered with filter holes 3. Eight trapezoidal positioning posts 4 are evenly distributed circumferentially on the inner wall of the inner cylinder 3. A slot 5 is formed between two adjacent positioning posts 4. A slide positioning frame 6 is installed in the slot 5. A downwardly extending sleeve 7 is connected to the center of the base plate 1. A connection hole 8 adapted to the centrifuge drive shaft is opened in the center of the sleeve 7.

[0019] The slide is inserted into the slide positioning frame 6, and the slide positioning frame 6 is engaged in the slot 5. When the drum rotates, each positioning post 4 drives the slide positioning frame 6 to rotate, thereby removing liquid from the slide on the slide positioning frame 6.

[0020] To enhance the support and positioning of the slide positioning holder 6, this embodiment preferably includes a support plate 9 within the slot 5. The support plate 9 is a flat plate perpendicular to the base plate 1. Its two edges are close to the inner wall of the inner cylinder 2 and are fixedly connected to adjacent positioning posts 4. The support plate 9 has numerous filter holes 3. When the slide positioning holder 6 is inserted into the slot 5, one side rests against the support plate 9.

[0021] like Figure 3 As shown, the slide positioning frame 6 in this embodiment includes a rectangular frame 601. The two opposite ends of the rectangular frame 601 are an insertion end 602 and a positioning end 603, respectively. The positioning end 603 is connected to two parallel positioning plates 604. The positioning plates 604 are provided with positioning slots 605 on the side facing the insertion end 602. Each positioning plate 604 is provided with a plurality of positioning slots 605 arranged sequentially along its length. The top and bottom of the rectangular frame 601 are respectively provided with limiting plates 606 parallel to the positioning plates 604. The two limiting plates 606 are inserted into the rectangular frame 601 on their opposite sides. The two limiting plates 606 are respectively provided with limiting slots 607 corresponding to the positioning slots 605 on their opposite surfaces. The slide is inserted into the rectangular frame 601 from the insertion end 602 and engages with the corresponding positioning slots 605 and limiting slots 606. Example 2

[0022] like Figure 4 As shown, this embodiment is based on embodiment 1, and further provides an outer cylinder 10 outside the inner cylinder 2. The outer cylinder 10 is generally in the shape of a cone with a larger top and a smaller bottom. The lower end of the outer cylinder 10 is fixedly and sealed to the lower end of the inner cylinder 2 or the outer edge of the bottom plate 1. The upper end of the outer cylinder 10 is lower than the upper end of the inner cylinder 2. The outer edge of the upper end of the inner cylinder 2 is connected to an outwardly extending baffle plate 11. The outer edge of the baffle plate 11 extends beyond the outer cylinder 10. There is an annular gap 12 between the baffle plate 11 and the top end of the outer cylinder 10. The baffle plate 11 is used to block the splashing of liquid thrown outward along the inner wall of the outer cylinder 10 and guide the liquid to flow outward of the outer cylinder 10.

[0023] The drum with outer cylinder 10 has the function of soaking in dye solution. The user can install the glass slide to be dyed on the glass slide positioning frame 6 of the drum, and then inject the dye solution into the drum to dye the glass slide. After dyeing for a certain time, the drum is rotated to throw the dye solution out from the annular gap 12 to de-dye the glass slide.

[0024] In actual use, the slide positioning holder 6 is inserted into the slot 5 in a multi-layered stack. Example 3

[0025] like Figure 5The centrifuge shown includes a base 13, a drive mechanism 14 fixedly connected to the base 13, a drum 16 connected to the end of a drive shaft 15 of the drive mechanism 14, and a cover 17. The cover 17 is connected to the upper surface of the base 13 and covers the drum 16. The drum 16 is the drum for descaling stained slides described in Embodiment 1 above. An annular flow channel 18 is formed between the cover 17 and the drum 16. A drain pipe 19 communicating with the annular flow channel 18 is provided on the base 13.

[0026] After staining, the slide, along with the slide positioning frame 6, is inserted into the slot 5 of the rotating drum 16. Then, the drive mechanism 14 is started, which drives the rotating drum 16 to rotate and remove the stained slide.

[0027] An air inlet pipe 20 is connected to the top of the cover 17. The air inlet pipe 20 communicates with the inside of the cover 17, and the outer end of the air inlet pipe 20 is used to connect to a hot air blower. By introducing hot air into the inside of the cover 17, the glass slide after liquid removal can be dried, and its surface can be dried quickly.

[0028] In this embodiment, the air inlet pipe 20 is preferably slidably connected to the cover 17. The cover 17 is connected to a lifting driver 21 that drives the air inlet pipe 20 to rise and fall. One end of the air inlet pipe 20 located inside the cover 17 is connected to a cover 22. The lower end of the cover 22 is directly opposite the upper end of the drum 16. A sealing ring 23 is provided at the lower end of the cover 22. When the cover 22 descends, it seals and connects with the top of the drum 17.

[0029] The drive mechanism 14 is a direct-drive motor.

[0030] The working process of this invention is as follows: Figure 5 As shown, the stained slide, along with the slide positioning frame 6, is inserted into the slot 5 of the rotating drum 16. Then, the drive mechanism 14 is started, which drives the rotating drum 16 to rotate and remove the liquid from the stained slide.

[0031] After the descaling is completed, the lifting driver 21 drives the air inlet pipe 20 and the cover 22 to descend, so that the cover 22 covers the upper end of the drum 16. Then, a hot air blower is used to introduce pure hot air into the drum 16 through the air inlet pipe 20. The hot air is concentrated in the drum 16 and escapes along the filter hole 3. Finally, it is discharged from the drain pipe 19, so that the staining liquid on the slide surface is dried.

[0032] By using a cover 22 to cover the drum 16, hot air can be prevented from flowing directly through the drain pipe 19 without effectively drying the glass slide, thus avoiding energy waste and improving energy efficiency.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some of the application examples, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
