Description

Technical Field

[0001] This utility model relates to the technical field of mud level monitoring in alumina settling tanks, and particularly to a mud level monitoring device for alumina settling tanks. Background Technology

[0002] In industrial production and environmental protection, alumina settling tanks are gravity sedimentation devices used to separate solid alumina from liquids, increasing the concentration of the suspension and simultaneously obtaining a clarified liquid. To monitor the sludge level at the bottom of the settling tank, a sludge level monitoring device is typically used for real-time detection. When the sludge level reaches the monitoring threshold, the sludge is quickly and intelligently discharged.

[0003] Conventional alumina settling tank sludge level monitoring devices detect the accumulation height of settled sludge through an internal sensor structure and transmit the data to a corresponding structure to monitor the sludge level. However, over prolonged use, this type of device can cause sludge to accumulate at the outer end of the detection device, affecting the accuracy of the sludge level detection. Chinese patent application number "CN200720022432.8" discloses an alumina settling tank sludge level monitoring device for detecting the sludge level in an alumina settling tank. Observation tubes are installed at intervals along the longitudinal height of the settling tank walls, and control valves can be connected to these tubes. The outer end of the control valves is connected to a delivery pipe inserted into a collection hopper. This method is simple, convenient, provides accurate detection and positioning, is low-cost, and easy to implement. However, this structure does not solve the problem of sludge level accumulation.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] refer to Figure 1-4The alumina settling tank sludge level monitoring device of this embodiment includes: a settling sludge level monitor 10, which realizes real-time detection of the settling sludge depth inside the alumina manufacturing settling tank 2, using a pressure detection algorithm. A settling sludge scraping plate 9 is slidably connected to the bottom of the settling sludge level monitor 10, and the settling sludge scraping plate 9 contacts the settling sludge. A side end connecting block 13 is fixedly connected to the side end of the settling sludge scraping plate 9, and a lifting connecting rod 6 is fixedly connected to the upper end of the side end connecting block 13. There are two lifting connecting rods 6, and a gripping handle 7 is fixedly connected between the lifting connecting rods 6. The device uses two settling sludge level monitors 10 to detect the settling sludge depth at different locations.

[0025] The sedimentation level monitor 10 is fixedly connected to the bottom of the alumina manufacturing sedimentation tank 2 to achieve alumina sedimentation and solid-liquid separation. An intermediate sealing plate 8 is installed in the middle section of the alumina manufacturing sedimentation tank 2. A movable connecting rod 14 is fixedly connected to the side of the intermediate sealing plate 8, and the movable connecting rod 14 is fixedly connected to the output end of the operating motor 15. This allows the intermediate sealing plate 8 to open, allowing the clarified liquid to be discharged from the lower end. A data detector 3 is fixedly connected to the outer end of the alumina manufacturing sedimentation tank 2 to store the sedimentation level data. The operating motor 15 is fixedly connected to the middle section of the alumina manufacturing sedimentation tank 2 to provide power for the movable connecting rod 14. The data detector 3 is connected to the sedimentation level monitor 10 via a second data transmission line 11, and to a data comparator 5 via a first data transmission line 4. This integrates sedimentation level data from different locations, further improving accuracy. The settling tank 2 used in alumina manufacturing is fixedly connected to a supporting base column 1 at its lower end, with two supporting base columns 1 in total. This provides overall structural support. A feeding bottom funnel 16, which is a metal structure, is connected to the bottom of the settling tank 2. The clarified liquid is transferred to the outside through the feeding bottom funnel 16. A discharge telescopic rod 12 is connected to the lower end of the feeding bottom funnel 16, and the end of the discharge telescopic rod 12 is fixedly connected to a bottom sealing plate 17. This seals the structure of the feeding bottom funnel 16, preventing leakage during use.

[0026] Working principle: When using this equipment, the raw material is fed into the settling tank 2 for alumina manufacturing, the settling device is started, and after settling is completed, the discharge telescopic rod is opened to open the sealed bottom sealing plate 17, thus completing the collection of clarified liquid.

[0027] When the outside of the sedimentation mud level monitor 10 is covered with a large amount of sedimentation mud, it drives the gripping handle 7, which moves upward through the lifting connecting rod 6 and the sedimentation mud scraping plate 9 to complete the cleaning of the sedimentation mud level. During the operation of the sedimentation mud level monitor 10, the height of the sedimentation mud level is calculated due to the different pressures generated by the sedimentation mud.

[0028] Because the sedimentation mud itself is irregularly accumulated, the sedimentation mud level will be different in different locations. By setting up multiple sedimentation mud level monitors 10 and comparing them with data detectors 3 and comparators, the detection accuracy can be further improved.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
