Abstract
The utility model discloses a device for preventing a discharge drum of a high-efficiency settling tank from being blocked, which comprises a high-efficiency settling tank (1) and an underflow pipe (4) connected with the bottom of the settling tank (1). The high-efficiency settling tank (1) is connected with the underflow pipe (4) by an underflow pump (2); a return flow pipeline (3) is parallelly connected with the underflow pump (2) and the high-efficiency settling tank (1); and one end of the return flow pipeline (3) is connected with the high-efficiency settling tank (1), and the other end thereof is connected with the underflow pipe (4). The device and the underflow pump are parallelly connected with the return flow pipeline, so that the high-efficiency settling tank, the underflow pump and the return flow pipe form a loop, the underflow of the high-efficiency settling tank is periodically returned into the high-efficiency settling tank by the return flow pipeline, the underflow is constantly circulated to remove the accumulation formed on the discharge drum on the lower part of the high-efficiency settling tank and avoid the phenomenon that the discharge drum at the bottom of the high-efficiency settling tank is blocked due to underflow accumulation with high solid content so as to shut down for cleaning.
Description
Technical field
The utility model relates to a kind of device that high rate settling discharging drum stops up that prevents of process for making alumina red-mud settlement separation circuit.
Background technology
In alumina producing, the settlement separate of red mud is an important link.After the bauxite stripping, formation contains the stripping slurries of red mud and sodium aluminate solution, slurries make red mud separate with sodium aluminate solution through the dilution back by sedimentation or filtration, sodium aluminate solution after the separation is sent to decompose and is produced aluminum oxide, and red mud needs washing, reduce alkali content wherein, to reclaim alkali and to make red mud reach the standard of effluxing.In alumina producing, generally adopt a plurality of subsiders to finish liquid, the solid separation and washing process.In the red-mud settlement separation and washing process of alumina producing, general employing underflow pump is delivered to a back subsider with the subsider underflow and is carried out the red mud backflush, and the high rate settling underflow contains height admittedly, be easy to deposition, cause high rate settling bottom discharging drum to stop up, cleaning is got up quite difficult, influences the operating rate and the production capacity of equipment, has a strong impact on production.
The utility model content
Technical problem to be solved in the utility model is, provide a kind of device that prevents that high rate settling discharging drum from stopping up, to solve the technical problem that contains height admittedly, deposits, causes high rate settling bottom discharging drum to stop up easily because of the high rate settling underflow in the prior art.
The technical solution of the utility model: this prevents the device that high rate settling discharging drum stops up, comprise high rate settling and the underflow pipe that is connected with the bottom of high rate settling, high rate settling is connected with underflow pipe by the underflow pump, be connected with reflux line side by side with the underflow pump, one end of this reflux line connects high rate settling, the other end connects underflow pipe, makes high rate settling, underflow pump and reflux line form a loop.
Described underflow pump is equipped with two side by side, directly draws from the high rate settling bottom respectively with two pipelines, meets at underflow pipe.
Connection between described each parts is flange and connects.
The utility model is according in alumina producing; with the underflow pump subsider underflow is delivered to a next subsider and carry out this condition of production of red mud backflush process; by being connected reflux line side by side with the underflow pump; thereby make high rate settling; underflow pump and reflux line form a loop; regularly arrange the high rate settling underflow to be returned high rate settling again by reflux line; underflow constantly circulates; the deposition that becomes at high rate settling bottom discharging cydariform is removed, avoided high rate settling bottom discharge drum to shut down cleaning because of height contains the obstruction of underflow deposition admittedly.Solved the problem that is always perplexing alumina producing sedimentation operation ordinary production for a long time.The red mud backflush process of subsider underflow is carried out smoothly, thereby provide sound assurance for the production of aluminum oxide.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: this structure that prevents the device that high rate settling discharging drum stops up as shown in the figure, comprise the underflow pipe 4 that high rate settling 1 is connected with bottom with high rate settling 1, high rate settling 1 is connected with underflow pipe 4 by underflow pump 2, underflow pump 2 is equipped with two side by side, directly draw from high rate settling 1 bottom respectively with two pipelines, meet at underflow pipe 4, be connected with reflux line 3 side by side with underflow pump 2, one end of this reflux line 3 connects high rate settling 1, and the other end connects underflow pipe 4.
Connection between each parts is flange and connects.
In the operational process of high rate settling 1, time opening reflux line 3 makes the high rate settling underflow return high rate settling again and circulates, and the deposition that discharging cydariform in high rate settling bottom becomes is removed, and closes after the cleaning to get final product again.
Claims (3)
1. one kind prevents the bulging device that stops up of high rate settling discharging, comprise the underflow pipe (4) that high rate settling (1) is connected with bottom with high rate settling (1), high rate settling (1) is connected with underflow pipe (4) by underflow pump (2), it is characterized in that: be connected with reflux line (3) side by side with underflow pump (2), one end of this reflux line (3) connects high rate settling (1), and the other end connects underflow pipe (4).
2. the device that prevents that high rate settling discharging drum from stopping up according to claim 1, it is characterized in that: described underflow pump (2) is equipped with two side by side, directly draws from high rate settling (1) bottom respectively with two pipelines, meets at underflow pipe (4).
3. according to claim 1, the 2 or 3 described devices that prevent that high rate settling discharging drum from stopping up, it is characterized in that: the connection between described each parts is flange and connects.
