Description

Technical Field

[0001] The utility model relates to the technical field of liquid sodium ethoxide production, in particular to a precipitation tank for liquid sodium ethoxide production. Background Art

[0002] There are two industrial preparation methods for sodium ethoxide, one is the metallic sodium process for producing sodium ethoxide, and the other is the alkaline process for producing sodium ethoxide. Since the raw materials used in the alkaline process for producing sodium ethoxide are readily available, the alkaline process has certain advantages over the metallic sodium process in the industrial preparation of sodium ethoxide. When using the alkaline process to prepare sodium ethoxide, sodium hydroxide is added to the alkali dissolving tank. As the reaction proceeds, solid precipitates such as Na2CO3, NaCl, and Fe2O3 will appear in the precipitation tank body. In order to continuously produce liquid sodium ethoxide, the precipitated substances in the precipitation tank body need to be removed.

[0003] However, traditional impurity removal methods are inefficient. Some traditional methods require manual cleaning of impurities, which is not only extremely labor-intensive but also disrupts production, severely impacting efficiency. For example, manual cleaning consumes considerable time and effort, and each cleaning operation can cause the production line to stop for a period of time, making it unsuitable for large-scale production. Utility Model Content

[0004] In order to solve the problems mentioned in the above background technology, the utility model provides a precipitation tank for producing liquid sodium ethoxide.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A precipitation tank for producing liquid sodium ethoxide comprises a precipitation tank body, wherein a receiving groove is provided on the inner wall of the bottom end of the precipitation tank body, and an impurity scraping mechanism is further provided in the precipitation tank body for scraping deposited impurities at the bottom end of the precipitation tank body into the receiving groove;

[0007] The impurity scraping mechanism includes a horizontally movable bracket, on which multiple first vertical shafts are rotatably installed, the bottom ends of the first vertical shafts are vertically movably sleeved with second vertical shafts, the bottom ends of the multiple second vertical shafts are rotatably connected to the top ends of the scrapers, an annular guide groove is fixed on the inner wall of the sedimentation tank body, a limiting rod is fixed on the scraper, and the limiting rod movably extends into the annular guide groove.

[0008] Preferably, a horizontally arranged threaded rod is rotatably installed inside the sedimentation tank body, and the threaded rod is driven to rotate by a third rotary motor fixed on the outer wall of the sedimentation tank body, and the thread of the threaded rod passes through the horizontal movable bracket.

[0009] Preferably, a horizontally arranged elastic telescopic rod is fixed in the ring near one side of the impurity reservoir, and an output end of the elastic telescopic rod is fixed with a wedge block, which is movably extended into the interior of the ring-shaped guide groove.

[0010] Preferably, a vertical protrusion is fixed to the outer portion of the first vertical shaft, and a vertical guide groove corresponding to the vertical protrusion is formed in the inner wall of the second vertical shaft, so that the second vertical shaft can only move vertically relative to the first vertical shaft.

[0011] Preferably, a straight gear is fixed to the top end of the first vertical shaft, a plurality of horizontally arranged racks are fixed in the interior of the precipitation tank body, the racks are in one-to-one engagement with the straight gear, and a plurality of stirring branches are fixed to the outer portion of the second vertical shaft.

[0012] Compared with the prior art, the present application has the following beneficial effects:

[0013] 1. The impurity scraping mechanism can scrape the deposited impurities at the bottom end of the precipitation tank body into the storage groove. The third rotary motor drives the threaded rod to rotate, thereby driving the horizontal moving support to move horizontally. The limiting rod on the scraper slides in the ring-shaped guide groove, so that the scraper can contact the inner wall at the bottom end of the precipitation tank body at a specific position, thereby scraping the deposited alkali sludge to the impurity reservoir, and realizing efficient impurity cleaning.

[0014] 2. When the scraper moves to the position of the wedge block, the limiting rod interacts with the wedge block, and under the cooperation of the elastic telescopic rod, the scraper can be separated from the inner wall at the bottom end of the precipitation tank body when returning, thereby achieving the purpose of one-way pushing of the alkali sludge into the interior of the impurity reservoir, and ensuring the accuracy and efficiency of impurity cleaning.

[0015] 3. The straight gear on the first vertical shaft is engaged with the rack in the precipitation tank body. During the movement of the horizontal moving support, the first vertical shaft and the second vertical shaft are driven to rotate, thereby causing the stirring branches to stir the liquid. This design accelerates the deposition process of impurities, improves production efficiency, and when the horizontal moving support moves back and forth, the stirring branches will stir at two different heights, thereby improving the stirring range, making the impurities in the liquid more easily deposited, and further optimizing the production process.

[0030] The inside of the precipitation tank body 1 is rotatably installed with a horizontally arranged threaded rod 9, the threaded rod 9 is driven to rotate by a third rotating motor 901 fixed on the outer wall of the precipitation tank body 1, and the threaded rod 9 is threadedly penetrated through the horizontal moving support 8.

[0031] The third rotating motor 901 can drive the threaded rod 9 to rotate, thereby driving the horizontal moving support 8 to move horizontally. Due to the existence of the annular guide groove 808, the limiting rod 807 slides along the annular guide groove 808. When the scraper 804 moves towards the storage groove 101 and the impurity reservoir 3, the limiting rod 807 moves along the lower horizontal groove, so that the scraper 804 reaches the lowest position and is in contact with the inner wall of the bottom end of the precipitation tank 1, thereby scraping the sludge deposited at the bottom of the precipitation tank 1 to the impurity reservoir 3.

[0032] The side ring of the annular guide groove 808 is fixedly provided with a horizontally arranged elastic expansion rod 10, the output end of the elastic expansion rod 10 is fixedly provided with a wedge block 1001, and the wedge block 1001 movably extends into the inside of the annular guide groove 808.
