Description

Technical Field

[0001] This utility model belongs to the field of salt solution purification, specifically relating to a settling tank for purifying salt solutions. Background Technology

[0002] Salt solution purification is a common process in many industrial production processes. Sedimentation purification is a frequently used method where solid particles suspended in brine, being denser than the brine itself, settle freely under gravity, separating the impurities from the clarified liquid. A continuously operating purification sedimentation tank is divided into four zones from top to bottom: the clarified liquid zone, the sedimentation zone, the transition zone, and the compression zone. In the clarified liquid zone, the brine is free of solid particles, and the clarified brine rises steadily, collects, and flows out.

[0003] Traditional settling tanks often cause significant disturbance to the existing brine solution during feeding, prolonging the settling time and thus affecting industrial production efficiency. Therefore, it is necessary to design a device to mitigate the disturbance of the incoming solution to the existing solution in the tank, thereby shortening the settling time and improving the settling effect. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an improved salt solution purification sedimentation tank.

[0005] A salt solution purification sedimentation tank consists of a top inlet (1), a central inlet pipe (2), a main tank body (3), a bottom main drain outlet (4), a dike (5) surrounding the main tank body at the top, and a discharge pipe (6) extending from the top of the dike. The bottom of the tank body is sloped, and the main drain outlet (4) is located at the bottom of the slope. To mitigate the disturbance caused by the inflowing solution to the existing solution in the tank, a buffer receiving trough (11) is provided below the inlet (1).

[0006] Preferably, the bottom of the main barrel (3) is a sloping bottom, which facilitates the discharge of settled solid waste, and the inclination angle of the cone bottom is preferably 10 to 30°.

[0007] Preferably, there is a support column (12) between the buffer receiving trough (11) and the central feed pipe (2) to stabilize the buffer receiving trough; there is also a support column (21) between the central feed pipe (2) and the main body (3) to stabilize the central feed pipe.

[0008] Preferably, the bottom of the buffer receiving trough (11) is also provided with a drain pipe (13) that extends through the central feed pipe (2) to the outside of the main barrel (3) for discharging solid substances deposited in the buffer receiving trough. A drain pipe valve a (14) is provided on the drain port at the end of the drain pipe a (13).

[0009] Preferably, the drain pipe (13) is inclined downward to facilitate the discharge of waste; the inclination angle of the drain pipe (13) relative to the horizontal line is preferably 10 to 45°.

[0010] Preferably, the main body (3) is provided with sight glasses a (31) and b (32) located on the top cover with the center of the top cover as the origin and spaced 30 to 90 degrees apart. There are also sight glasses c (33) located in the middle of the body and sight glasses d (34) located at the bottom of the body, for observing the sedimentation of the liquid in the body.

[0011] Preferably, the main barrel body (3) is provided with manholes (35) and (36) above the top embankment (5) and in the middle and lower parts, respectively, for manual inspection and cleaning when necessary.

[0012] Preferably, the top cover of the main barrel body (3) is also provided with an exhaust port (37) with a filter screen.

[0024] like Figure 1 The high-efficiency purification aging tank shown is composed of a top feed inlet (1), a buffer receiving trough (11), a support column a (12), a drain pipe a (13), a drain pipe valve a (14); a central feed pipe (2), a support column b (21); a main tank body (3), a sight glass a (31), a sight glass b (32), a sight glass c (33), a sight glass d (34), a manhole a (35), a manhole b (36), an exhaust port (37); a main drain outlet (4), an auxiliary drain outlet (41); a dike (5); a discharge pipe (6), a discharge pipe valve (61), a drain pipe b (62), and a drain pipe valve b (63).

[0025] The top feed inlet (1) is located in the center of the top cover of the main body of the barrel; the receiving trough (11) is located directly below the feed inlet (1), and there is a support column (12) between the buffer receiving trough (11) and the central feed pipe (2) for support and fixation; the bottom of the receiving trough (11) is provided with a drain pipe a (13), which passes through the central feed pipe (2) and extends to the outside of the main body of the barrel (3) for discharging the solid material deposited in the buffer receiving trough. A drain pipe valve a (14) is provided on the drain port at the end of the drain pipe a (13).

[0026] It should be noted that the receiving trough buffers the impact of liquid from the upper feed pipe on the bottom of the aging tank and reduces disturbance to the liquid inside the tank during feeding, thus lowering the probability of turbidity in the solution. The drain pipe at the bottom of the receiving trough can discharge accumulated waste into the tank.

[0027] The central feed pipe (2) is located outside the buffer receiving trough (11). There are support columns (21) on both sides of the central feed pipe (2) connected to the main body (3) for support and fixation. The bottom of the central feed pipe (2) is hollow and maintains a distance of 1.5 meters from the bottom of the purification sedimentation tank.

[0028] The main body (3) is equipped with four sight glasses. Sight glasses a (31) and b (32) are located on the top cover and are at a 60° angle with the center of the top cover as the center point. They are used to observe the state of the salt solution after sedimentation. Sight glasses c (33) and d (34) are distributed on one side of the body, located in the middle and lower parts of the body, respectively. They are used to observe the state of the solution at different heights inside the body so as to adjust the feeding speed in time. The sight glasses can also be used to observe the condition of dirt inside the body so as to drain and clean it in time.

[0029] The main barrel body (3) is also provided with manhole a (35) and manhole b (36), which are located at the upper and lower parts of the barrel body, making it convenient for workers to enter and exit for inspection and cleaning of stubborn dirt inside the barrel.

[0030] The main body (3) is also provided with an exhaust port (37) on top, and a filter screen is provided at the outlet. The filter screen at the exhaust port can prevent dust and other pollutants in the air from entering the settling tank.

[0031] The bottom of the main barrel (3) is provided with a 30° slope, so that the deposited impurities and dirt can be accumulated by their own gravity and discharged to the main drain (4) and auxiliary drain (41) at the bottom of the aging barrel. The main drain (4) and auxiliary drain (41) can be opened at different times or fully opened depending on the condition of the dirt at the bottom to clean the deposited dirt and impurities. The main drain (4) and auxiliary drain (41) are on the same horizontal plane and are both located at the lowest point of the bottom slope of the barrel.

[0032] The embankment (5) surrounds the inner wall of the barrel. The main body of the barrel above the embankment (5) is provided with a discharge pipe (6), and a discharge pipe valve (61) is provided at the discharge port at its end. A sewage pipe b (62) is led down before the discharge pipe valve (61), and a sewage pipe valve b (63) is provided on the sewage pipe b (62).

[0033] It should be noted that the central feed pipe (2) separates the feed area from the settling area, while the cofferdam (5) separates the settling area from the clearing area. After the salt solution is purified by settling, it overflows into the cofferdam after reaching one side and enters the next stage of collection and treatment through the outlet. The cofferdam also serves to prevent liquid disturbance.

[0034] The working principle of this utility model is as follows:

[0035] The pre-treated salt solution is added into the purification settling tank through the inlet (1). It first enters the buffer receiving tank (11). After the buffer receiving tank (11) is full, it will slowly overflow and move slowly towards the bottom of the tank through the central feed pipe (2). Then, it will gradually overflow upwards in the part between the central feed pipe (2) and the main tank body (3). During this process, the solid matter slowly settles to the bottom of the tank under the action of gravity, and the liquid becomes clearer and clearer. When the liquid level reaches the weir (5), the solution is relatively clear. After the clear salt solution overflows the weir, it will flow out from the outlet pipe (6). The valve (61) at the outlet can be opened to discharge the solution.

[0036] When a large amount of settled dirt appears in the buffer receiving trough (11), the cofferdam (5), and the bottom of the tank (3), it can be rinsed and discharged through the drain pipe a (13), drain pipe b (62), and main drain outlet (4), respectively. If necessary, personnel can enter the settling tank through manhole a (35) and manhole b (36) to clean the settling tank more thoroughly.
