Description

Technical Field

[0001] The utility model relates to the technical field of washing towers, in particular to a stable washing tower which can effectively prevent blockage. Background Art

[0002] In coal gasification technology, raw coal and oxygen generate synthesis gas through gasification reaction. The synthesis gas contains a large amount of dust particles, which need to be gradually removed by washing equipment. Then the synthesis gas with low dust content is transported to the next stage for processing and application.

[0003] At present, a Chinese patent discloses a stable washing tower that is anti-clogging (publication number CN218089455U). When the utility model is implemented, the circulation pump is started, and the circulation pump filters the high-temperature gray water in the washing tower body through the filter cartridge and then sucks it into the liquid guide pipe. The high-temperature gray water between the filter cartridge and the side wall of the washing tower body is filtered to avoid clogging caused by too many impurities.

[0004] During the process of the circulating pump circulating and extracting the high-temperature washing ash water, the high-temperature washing ash water carries impurities and adheres to the surface of the filter cartridge. During the continuous operation of the device, the impurities adhered to the surface of the filter cartridge will accumulate more and more, which will undoubtedly affect the normal extraction of the high-temperature washing ash water by the circulating pump. In severe cases, it may even cause the filter cartridge to be blocked, making it difficult for the circulating pump to ensure the normal circulation of the high-temperature washing ash water.

[0005] Therefore, a stable washing tower which can effectively prevent clogging is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a stable washing tower which can effectively prevent clogging in order to solve the above problems, thereby improving the problem that the filter structure of the existing stable washing tower is easily clogged when circulating water, thus affecting the normal operation of the stable washing tower.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme. A stable washing tower that can effectively prevent blockage includes: a stable washing tower body, the surface of the stable washing tower body is fixedly connected and connected with a reflux pipe, and one end of the reflux pipe is fixedly connected and connected with a circulation pump; a filtering device, the filtering device used to avoid clogging of the circulation pump is fixedly connected and connected between the stable washing tower body and the circulation pump; the filtering device includes a mounting plate fixedly connected to the inner wall of the stable washing tower body, one end of the mounting plate penetrates to the outside of the stable washing tower body, the other end of the mounting plate is fixedly connected to a liquid guide tube, one end of the liquid guide tube penetrates the mounting plate and is fixedly connected and connected to the circulation pump, the other end of the mounting plate is fixedly connected to an anti-blocking filtering mechanism, one end of the anti-blocking filtering mechanism penetrates to the outside of the mounting plate, and one end of the anti-blocking filtering mechanism is installed with a driving mechanism fixedly connected and connected to the liquid guide tube.

[0008] Preferably, the anti-clogging filter mechanism includes a disc-shaped filter screen and a scraper, the disc-shaped filter screen is rotatably connected to the other end of the mounting plate, one end of the disc-shaped filter screen is flush with the other end of the mounting plate, and the other end of the liquid guide tube is in pressure-free contact with the other end of the disc-shaped filter screen, and the other end of the disc-shaped filter screen is fixedly connected to a connecting shaft, and the other end of the connecting shaft passes through the outside of the mounting plate, and the scraper is fixedly connected to the other end of the mounting plate, and one end of the scraper is in pressure-free contact with the disc-shaped filter screen, and the scraper is an austenitic chromium-nickel stainless steel material component. While the disc-shaped filter screen is normally filtering impurities, the staff only needs to rotate the connecting shaft, and the connecting shaft drives the disc-shaped filter screen to rotate, and the disc-shaped filter screen drives the impurities to rotate. At this time, the scraper scrapes off the impurities adhered to the surface of the disc-shaped filter screen, so that the disc-shaped filter screen is always kept clean, which can enable the washing high-temperature gray water to stably pass through the disc-shaped filter screen, and can ensure the flow rate of the circulating washing high-temperature gray water, so as to ensure the normal circulation of the washing high-temperature gray water.

[0009] Preferably, a first sealing bearing is fixedly connected to the surface of the connecting shaft, and the first sealing bearing is embedded and installed inside the mounting plate, which can seal the gap between the mounting plate and the connecting shaft to avoid leakage of high-temperature gray water for washing inside the stable washing tower body.

[0010] Preferably, a sealing ring is provided on the surface of the disc-shaped filter screen, and the sealing ring is fixedly connected to the inner wall of the mounting plate. This can seal the gap between the disc-shaped filter screen and the mounting plate without affecting the rotation of the disc-shaped filter screen, so as to prevent impurities from entering the gap and reduce the rotation resistance of the disc-shaped filter screen.

[0011] Preferably, the driving mechanism includes a circular box fixedly connected and connected to the surface of the return pipe, one end of the connecting shaft passes through the interior of the circular box, and the surface of the connecting shaft is fixedly connected with evenly distributed guide plates; the guide plates are distributed on the surface of the connecting shaft in a ring shape around the axis of the connecting shaft, and in the process of the high-temperature washing gray water flowing in the liquid guide pipe, the high-temperature washing gray water is guided by the liquid guide pipe through the circular box, and at this time the guide plate blocks the normal passage of the high-temperature washing gray water, and when the suction force of the circulating pump on the high-temperature washing gray water is greater than the blocking force of the guide plate, the high-temperature washing gray water will push the guide plate, and the guide plate drives the connecting shaft to rotate, which does not require the staff to manually drive the connecting shaft to complete the cleaning work, and the driving mechanism drives the connecting shaft to rotate only when the circulating pump extracts the high-temperature washing gray water, and there is no need to set a separate driving and control structure for the anti-clogging filter mechanism, thereby reducing the use cost of the anti-clogging filter mechanism.

[0012] Preferably, the two connecting points between the round box and the liquid guiding tube are both arranged below the connecting shaft, and the two connecting points between the round box and the liquid guiding tube are symmetrically distributed on both sides of the axis of the connecting shaft. The straight-line distance between the connecting point between the round box and the liquid guiding tube and the connecting shaft is the same as the length of the guide plate, which can ensure that the high-temperature gray water for washing always flushes the guide plate below the connecting shaft in a single direction, thereby ensuring that the disc-shaped filter can rotate stably.

[0013] Preferably, a second sealing bearing is embedded in the inner wall of the round box, and the inner edge of the second sealing bearing is fixedly connected to the connecting shaft, which can seal the gap between the connecting shaft and the round box to prevent leakage of high-temperature gray water during washing.

[0014] The beneficial effects of the utility model are:

[0015] 1. While the disc filter is filtering impurities normally, the staff only needs to rotate the connecting shaft, which drives the disc filter to rotate, and the disc filter drives the impurities to rotate. At this time, the scraper scrapes off the impurities adhering to the surface of the disc filter, so that the disc filter is always kept clean. This enables the washing high-temperature ash water to pass through the disc filter stably, and can ensure the flow rate of the circulating washing high-temperature ash water, so as to ensure the normal circulation of the washing high-temperature ash water;

[0016] 2. During the flow of high-temperature washing ash water in the liquid guide pipe, the high-temperature washing ash water is guided by the liquid guide pipe through the round box. At this time, the guide plate blocks the normal passage of the high-temperature washing ash water. When the suction force of the circulating pump on the high-temperature washing ash water is greater than the blocking force of the guide plate, the high-temperature washing ash water will push the guide plate, and the guide plate drives the connecting shaft to rotate. This does not require the staff to manually drive the connecting shaft to complete the cleaning work, and the driving mechanism drives the connecting shaft to rotate only when the circulating pump extracts the high-temperature washing ash water. There is no need to set a separate driving and control structure for the anti-clogging filter mechanism, thereby reducing the use cost of the anti-clogging filter mechanism.
