Description

Technical Field

[0001] This application relates to the field of pathology waste wax recycling technology, and more particularly to a regeneration device for recycling pathology waste wax. Background Technology

[0002] Histological slide preparation commonly employs the FFPE (Formalin-Fixed, Paraffin-Embedded) process. Hospital pathology departments continuously generate waste wax / wax residue during tissue processing (dehydration, clearing, paraffin embedding), embedding, trimming and sectioning, water bath spreading, drying, and equipment cleaning and maintenance. Particularly during pathological sectioning, paraffin is frequently used as an embedding agent to fix tissue in paraffin blocks for sectioning; however, the waste wax generated in this process usually contains tissue fragments, cellular debris, and other impurities.

[0003] Traditional waste wax recycling equipment typically employs a single filtration method when processing waste wax. For example, the pathological dehydration waste paraffin recycling and purification device disclosed in patent publication number CN220364502U primarily uses a fine-mesh filter for filtration. However, the waste wax produced from pathological sections contains complex and numerous impurities, easily leading to clogging of the filtration equipment and affecting recycling efficiency and quality. Therefore, developing a recycling device that can effectively handle impurities in waste wax is of great significance for improving waste wax recycling efficiency and reducing environmental pollution. Utility Model Content

[0009] Furthermore, the crushing chamber includes: a feed funnel; A feed pipe, one end of which is connected to the crushing chamber and the other end of which is connected to the feed funnel; A pulverizing blade is disposed inside the feed pipe and is used to pulverize waste wax located inside the feed pipe.

[0010] Furthermore, the centrifuge chamber includes: a chamber body; A storage door, which is installed on the storage body; A drain pipe is installed on the silo body and connected to the centrifuge.

[0011] Furthermore, the regeneration device also includes: a molding template, an opening on the side of the molding chamber, the molding template being slidably disposed within the molding chamber along the opening, and used to cool the wax liquid discharged from the centrifuge.

[0022] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0023] This utility model provides, for example Figures 1 to 3 The device shown is a recycling apparatus for recovering waste wax from pathology departments, designed to address the shortcomings of existing waste wax recovery equipment in pathology departments, which is prone to clogging.

[0024] The recycling system for pathology waste wax mainly includes: a pulverizing chamber 100, a sedimentation chamber 200, a centrifuge chamber 300, and a molding chamber 400. Figure 2As shown, the crushing chamber 100, sedimentation chamber 200, centrifugation chamber 300, and forming chamber 400 are arranged sequentially from top to bottom. The crushing chamber 100 is used to crush waste wax and form waste wax powder, which falls into the sedimentation chamber 200. A heater 210 is installed in the sedimentation chamber 200 to heat the sedimentation chamber 200, thereby melting the waste wax powder into wax liquid. The bottom left end of the sedimentation chamber 200 is inclined downwards. Impurities in the wax liquid will move to the left end due to gravity (in addition to paraffin wax, waste wax also contains impurities such as tissue, whose density is generally greater than that of liquid paraffin wax, so it is easy to settle to the bottom. Since the bottom of the sedimentation chamber 200 is inclined, they will be concentrated at the left end). One end of the overflow pipe 220 is located at the right end of the sedimentation tank 200 (higher than the bottom surface of the sedimentation tank 200), so it can be kept away from impurities in the wax liquid. The other end is connected to the centrifuge 340 in the centrifuge tank 300. When the wax liquid in the sedimentation tank 200 exceeds the limit, the wax liquid can flow into the centrifuge 340 in the centrifuge tank 300 through the overflow pipe 220. The centrifuge 340 separates the solid impurities in the wax liquid and discharges the separated wax liquid into the molding tank 400. The molding tank 400 cools the wax liquid to form solid paraffin wax, thereby completing the recycling and regeneration.

[0025] Traditional waste wax recycling equipment typically employs a single filtration method when processing waste wax. For example, the pathological dehydration waste paraffin recycling and purification device disclosed in patent publication number CN220364502U primarily uses a fine-mesh filter for filtration. However, the waste wax produced from pathological sections contains complex and numerous impurities, easily leading to clogging of the filtration equipment and affecting recycling efficiency and quality. Therefore, developing a recycling device that can effectively handle impurities in waste wax is of great significance for improving waste wax recycling efficiency and reducing environmental pollution.

[0026] This invention uses a crushing chamber 100 to form waste wax powder that falls into a settling chamber 200. Because the waste wax powder is small in size, it is easy to melt and does not easily disturb the solid impurities at the bottom of the settling chamber 200. The settling chamber 200 can perform coarse filtration of the wax liquid, while the centrifugation chamber 300 performs fine filtration of the wax liquid. Compared with a single filter screen 221, this invention can effectively avoid clogging of the filtration equipment and greatly improve the recycling efficiency and quality.

[0027] In some embodiments, such as Figure 2 As shown, the overflow pipe 220 is vertically arranged, and an opening is provided radially at its upper end, with a filter screen 221 covering the opening. The opening is radially positioned to prevent the pulverized waste wax powder in the pulverizing chamber 100 from falling directly into the opening. When the height of the wax liquid in the sedimentation chamber 200 exceeds the opening, the wax liquid can flow along the opening into the centrifuge 340 in the centrifuge chamber 300. The filter screen 221 is preferably a stainless steel filter screen 221, with a filtration accuracy of coarse filtration, such as 2mm or more, to reduce the probability of clogging.

[0028] In some embodiments, such as Figures 1 to 2 As shown, the regeneration device further includes: a first waste port 202, and a sedimentation end 201 formed at the left end of the sedimentation chamber 200. The first waste port 202 is disposed on the sedimentation end 201 and used to discharge waste. In actual use, impurities in the wax liquid will move to the left end and concentrate due to gravity. When there are too many impurities in the sedimentation chamber 200, the wax liquid and impurities in the sedimentation chamber 200 can be discharged through the first waste port 202.

[0029] In some embodiments, such as Figure 2 As shown, the regeneration device also includes a disinfection module 230, which is disposed within the sedimentation chamber 200. The disinfection module 230 is used to sterilize the wax liquid within the sedimentation chamber 200. The disinfection module 230 may be an ultraviolet lamp and / or an ozone generation module, which can sterilize the wax liquid within the sedimentation chamber 200 to reduce the survival rate of pathogens and reduce biosafety risks.

[0030] In some embodiments, such as Figures 1 to 3 As shown, the pulverizing chamber 100 includes a feed funnel 110, a feed pipe 120, and a pulverizing blade 130. One end of the feed pipe 120 is connected to the pulverizing chamber 100, and the other end is connected to the feed funnel 110. The pulverizing blade 130 is disposed inside the feed pipe 120. In actual use, waste wax can be poured into the feed funnel 110. After entering the feed pipe 120, the waste wax is pulverized by the pulverizing blade 130 to form waste wax powder. The rotation speed of the pulverizing blade 130 can be adjusted according to the actual situation to control the coarseness of the waste wax powder.

[0031] In some embodiments, such as Figures 1 to 2 As shown, the centrifuge chamber 300 includes a chamber body 310, a chamber door 320, and a drain pipe 330. The drain pipe 330 is installed on the chamber body 310 and connected to the centrifuge 340. The chamber door 320 is installed on the chamber body 310. In actual use, solid impurities in the wax liquid can be discharged through the drain pipe 330. After long-term use, the centrifuge 340 can be cleaned by opening the chamber door 320.

[0032] In some embodiments, such as Figure 2 As shown, the regeneration device also includes a molding template 500. An opening is provided on the side of the molding chamber 400. The molding template 500 is slidably disposed in the molding chamber 400 along the opening. The molding template 500 can be inserted into or pulled out of the molding chamber 400. When the molding template 500 is located in the molding chamber 400, the molding template 500 can receive the wax liquid discharged by the centrifuge 340. After the wax liquid in the molding template 500 cools down, it can be removed, thereby completing the paraffin wax regeneration step.

[0033] In some embodiments, such as Figure 2As shown, the regeneration device also includes a water-cooled plate 600, which is embedded in the bottom surface of the molding chamber 400 and is thermally connected to the molding template 500. The water-cooled plate 600 is connected to a circulating coolant, thereby cooling the molding template 500 and accelerating the molding of the wax liquid inside the molding template 500.

[0034] In some embodiments, such as Figure 2 As shown, the regeneration device also includes a vibrating screen 700, which separates the crushing chamber 100 from the settling chamber 200. The vibrating screen 700 is used to filter waste wax powder. Preferably, the crushing blade 130 can be made of plastic. Due to its low hardness, it is not easy to cut other impurities with higher hardness while crushing waste wax. The impurities are larger in size and are therefore easier to be screened out by the vibrating screen 700.

[0035] In some embodiments, such as Figure 2 As shown, the regeneration device also includes a second waste port 101, which is located at the left end of the crushing chamber 100. The left end of the vibrating screen 700 is inclined downward to facilitate the cleaning of impurities on the vibrating screen 700 through the second waste port 101.

[0036] In summary, this invention provides a regeneration device for recovering waste paraffin from a pathology department, comprising a crushing chamber, a sedimentation chamber, a centrifuge chamber, a molding chamber, and an overflow pipe. The waste paraffin powder formed in the crushing chamber passes through the sedimentation chamber to form a liquid paraffin. The bottom of the sedimentation chamber is inclined. One end of the overflow pipe is located inside the sedimentation chamber to discharge the liquid paraffin into a centrifuge within the centrifuge chamber for secondary separation before entering the molding chamber to form solid paraffin. This invention uses the waste paraffin powder formed in the crushing chamber to fall into the sedimentation chamber. Due to the small volume of the waste paraffin powder, it melts easily and does not easily disturb the solid impurities at the bottom of the sedimentation chamber. The sedimentation chamber can perform coarse filtration of the liquid paraffin, while the centrifuge chamber performs fine filtration. Compared to a single filter screen, this effectively avoids clogging of the filtration equipment, significantly improving recovery efficiency and quality.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
