Description

Technical Field

[0001] This utility model relates to the field of condensate collection technology, specifically a condensate collection device for an MVR evaporator used in electrolytic aluminum ash treatment. Background Technology

[0002] MVR evaporators are high-efficiency and energy-saving evaporation equipment. Their principle involves using a high-efficiency steam compressor to compress the secondary steam generated during evaporation, increasing its pressure and temperature, and then using it as a heat source to achieve continuous evaporation. The core of this technology is using the heated secondary steam, compressed to raise its temperature, as a heat source to replace fresh steam, thus reducing the demand for external energy. MVR evaporators mainly consist of a heating chamber, a separation / crystallization chamber, a forced circulation pump, and a compressor. They are suitable for evaporation, concentration, crystallization, and drying processes in industries such as chemical, pharmaceutical, food, and environmental protection, and have unique advantages, especially in treating high-salt wastewater and heat-sensitive materials.

[0003] When electrolytic aluminum ash is evaporated through an MVR evaporator, cooling is required, which involves using condensate. However, the condensate needs to be collected and reused, so it needs to be filtered during the collection process to avoid impurities from affecting the condensation effect. During filtration, the filter plates are easily clogged, and direct replacement and cleaning would waste a lot of time. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a condensate collection device for an MVR evaporator used in the treatment of electrolytic aluminum ash, including a collection box, a drain pipe installed on the surface of the collection box, a filter inclined plate fixedly connected to the inner wall of the collection box, an installation shell fixedly connected to the surface of the collection box, a hydraulic electric push rod installed inside the installation shell, a right-angle scraper fixedly connected to the output end of the hydraulic electric push rod, a limit hole formed on the surface of the right-angle scraper, a limit post fixedly connected to the inner wall of the collection box, a fixing plate fixedly connected to the top of the filter inclined plate, a connecting plate fixedly connected to the end of the limit post away from the hydraulic electric push rod, a locking plate snapping into the inside of the filter inclined plate, and a partition plate fixedly connected to the inner wall of the collection box.

[0005] The above technical solution, by setting up a filter inclined plate and a scraper, allows condensate to fall from the top right end of the collection box onto the surface of the filter inclined plate. After being filtered by the filter inclined plate, the condensate falls into the inside of the collection box. The retaining plate is then pulled out from inside the filter inclined plate, and the hydraulic electric push rod is activated. The output end of the hydraulic electric push rod drives the right-angle scraper to move on the surface of the filter inclined plate, scraping the dust and impurities on the surface of the filter inclined plate to the right end of the partition plate for collection. This avoids clogging of the filter inclined plate surface during the long-term collection of condensate, which would prevent the condensate collection and filtration work from being impossible.

[0006] As a further improvement to the above solution, the inlet end of the drain pipe is located inside the collection box, the mounting shell is located on the surface near one end of the drain pipe, and the output end of the hydraulic electric push rod penetrates the inner wall of the collection box.

[0007] With the above technical solution, the inlet end of the drain pipe is located inside the collection box, ensuring that the condensate in the collection box can be discharged smoothly through the drain pipe. The output end of the electric push rod penetrates through the inner wall of the collection box, making it easy for the scraper to clean the surface of the filter inclined plate.

[0008] As a further improvement to the above solution, two limiting holes are provided, and the two limiting holes are evenly distributed symmetrically around the center of the front of the right-angle scraper. The limiting holes are slidably connected to the surface of the limiting post.

[0009] With the above technical solution, the two limiting holes are symmetrically and evenly distributed around the center of the front of the right-angle scraper and are slidably connected to the surface of the limiting post. This symmetrical distribution ensures that the right-angle scraper is subjected to uniform force during movement, thus ensuring its stability and enabling more effective scraping of impurities or other related operations.

[0010] As a further improvement to the above solution, one end of the connecting plate is fixedly connected to the inner wall of the collection box, and the bottom of the card plate penetrates through the bottom of the filter inclined plate.

[0011] With the above technical solution, one end of the connecting plate is fixed to the inner wall of the collection box, which enhances the connection stability between the limiting column and the collection box and ensures the reliability of the entire structure during operation. The bottom of the card plate penetrates the bottom of the filter inclined plate, which helps to better fix the filter inclined plate and prevent it from shifting during operation, ensuring that the filter inclined plate performs the filtration work stably.

[0012] As a further improvement to the above solution, a slide rail is fixedly connected to the inner wall of the collection box, a slide bar is slidably connected inside the slide rail, a collection cabinet is fixedly connected to the surface of the slide bar, and a handle is fixedly connected to the front of the collection cabinet.

[0013] With the above technical solution, the collection cabinet is fixedly connected to the surface of the slide bar, which facilitates the collection of certain substances. The handle is fixed to the front of the collection cabinet, which makes it easy for operators to pull out the collection cabinet for cleaning or other operations.

[0014] As a further improvement to the above solution, two slide rails are provided, and the two slide rails are evenly distributed symmetrically around the center of the rear surface of the collection box.

[0015] With the above technical solution, the two slide rails are symmetrically and evenly distributed around the center of the rear surface of the collection box. This symmetrical distribution ensures that the collection box is subjected to uniform force during sliding, guaranteeing the smoothness of its sliding and improving the reliability and stability of the entire device during use.

[0016] As a further improvement to the above solution, the collection cabinet is located on the surface away from the drain pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention uses a filter inclined plate and a scraper to remove the card plate from the inside of the filter inclined plate. Activating the hydraulic electric push rod causes the output end of the hydraulic electric push rod to move the right-angle scraper on the surface of the filter inclined plate, scraping dust and impurities on the surface of the filter inclined plate to the right end of the partition plate for collection. This avoids clogging of the filter inclined plate surface during prolonged condensate collection, preventing the condensate collection and filtration process from becoming impossible.

[0019] This utility model features a collection cabinet. By pulling the handle, the slider slides on the surface of the slide rail, and the collection cabinet is completely removed from the inside of the collection box, facilitating the subsequent collection and cleaning of impurities.

[0027] Example:

[0028] Please combine Figure 1-5 This embodiment discloses a condensate collection device for an MVR evaporator used in the treatment of electrolytic aluminum ash. The device includes a collection box 1, a drain pipe 2 mounted on the surface of the collection box 1, a filter inclined plate 3 fixedly connected to the inner wall of the collection box 1, a mounting shell 4 fixedly connected to the surface of the collection box 1, a hydraulic electric push rod 5 installed inside the mounting shell 4, a right-angle scraper 6 fixedly connected to the output end of the hydraulic electric push rod 5, a limit hole 7 formed on the surface of the right-angle scraper 6, a limit post 8 fixedly connected to the inner wall of the collection box 1, a fixing plate 9 fixedly connected to the top of the filter inclined plate 3, and the end of the limit post 8 furthest from the hydraulic electric push rod 5. A connecting plate 10 is fixedly connected, a clamping plate 11 is snapped into the inside of the filter inclined plate 3, and a partition plate 12 is fixedly connected to the inner wall of the collection box 1. Condensate falls from the top right end of the collection box 1 onto the surface of the filter inclined plate 3, and after being filtered by the filter inclined plate 3, it falls into the inside of the collection box 1. The clamping plate 11 is pulled out from the inside of the filter inclined plate 3, and the hydraulic electric push rod 5 is activated. The output end of the hydraulic electric push rod 5 drives the right-angle scraper 6 to move on the surface of the filter inclined plate 3, scraping the dust and impurities on the surface of the filter inclined plate 3 to the right end of the partition plate 12 for collection.

[0029] The inlet of the drain pipe 2 is located inside the collection box 1, the mounting shell 4 is located on the surface near one end of the drain pipe 2, and the output end of the hydraulic electric push rod 5 penetrates the inner wall of the collection box 1.

[0030] There are two limiting holes 7. The two limiting holes 7 are evenly distributed symmetrically around the center of the front of the right-angle scraper 6. The limiting holes 7 are slidably connected to the surface of the limiting post 8.

[0031] One end of the connecting plate 10 is fixedly connected to the inner wall of the collection box 1, and the bottom of the card plate 11 penetrates the bottom of the filter inclined plate 3.

[0032] The inner wall of the collection box 1 is fixedly connected to a slide rail 13, the slide rail 13 is slidably connected to a slide bar 14, the surface of the slide bar 14 is fixedly connected to a collection cabinet 15, and the front of the collection cabinet 15 is fixedly connected to a handle 16.

[0033] There are two slide rails 13, which are evenly distributed symmetrically around the center of the rear surface of the collection box 1.

[0034] The collection cabinet 15 is located on the surface away from the drain pipe 2.

[0035] The implementation principle of the condensate collection device for an MVR evaporator used in the treatment of electrolytic aluminum ash in this embodiment is as follows: When collecting condensate from electrolytic aluminum, the condensate is first dropped from the top right end of the collection box 1 onto the surface of the filter inclined plate 3, and after being filtered by the filter inclined plate 3, it falls into the inside of the collection box 1. The clamping plate 11 is pulled out from the inside of the filter inclined plate 3, and the hydraulic electric push rod 5 is activated. The output end of the hydraulic electric push rod 5 drives the right-angle scraper 6 to move on the surface of the filter inclined plate 3, scraping the dust and impurities on the surface of the filter inclined plate 3 to the right end of the partition plate 12 for collection. This avoids the filter inclined plate surface from becoming clogged during the long-term collection of condensate, which would prevent the condensate collection and filtration work from being carried out.

[0036] The scraper scrapes the dust off to the right end of the partition plate 12 and then it falls into the collection cabinet 15. By pulling the handle 16 through the collection cabinet 15, the slide bar 14 slides on the surface of the slide rail 13 and the collection cabinet 15 is completely pulled out of the collection box 1, which facilitates the subsequent collection and cleaning of impurities.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
