Detailed Description
The utility model is further elucidated below in conjunction with the accompanying drawings.
The orientations referred to in the present specification are all based on the orientations of the special device for purging sediment in a storage tank during normal operation, and are not limited to the orientations during storage and transportation, and represent only relative positional relationships and not absolute positional relationships.
Example 1:
as shown in fig. 1-6, a special device for purging sediment in a storage tank comprises a storage tank 1 and a purging mechanism 2, wherein a liquid inlet 11 is arranged at the top of the storage tank 1, and a liquid outlet 12 is arranged on the side wall of the storage tank 1. The storage tank 1 in this embodiment is mainly used for storing alkali liquor. The alkali liquor is injected into the storage tank 1 through the liquid inlet 11, and is discharged through the liquid outlet 12 when the storage tank is in use. Since the alkali liquor precipitates crystals during storage, the crystals combine at the bottom of the storage tank 1 to form bulk materials which are difficult to clean, and when the crystals accumulate to a certain extent, the liquid outlet 12 is also easily blocked. Therefore, in order to prevent crystal accumulation, the present embodiment introduces the purge mechanism 2.
The purging mechanism 2 comprises an air bag 21 and a plurality of air blowing ports 22 blowing air into the storage tank 1, wherein the air bag 21 is arranged on the side wall of the storage tank 1, and the air blowing ports 22 are positioned between the liquid outlet 12 and the bottom of the storage tank 1. After the alkaline solution floods the air-blowing port 22, the air bag 21 starts to supply air to the air-blowing port 22. At this time, the gas discharged from the gas blowing port 22 forms a large number of bubbles in the alkali liquor, and the bubbles are continuously broken to form smaller bubbles in the process of upward movement, so that the alkali liquor is rolled by the smaller bubbles. Under the drive of the small bubbles, the crystals precipitated in the alkali liquor move along with the bubbles, and after the bubbles are broken, the crystals slowly fall down, so that the crystals cannot be accumulated at the bottom of the storage tank 1. When the liquid is discharged, the crystallization is followed by the discharge of the lye. Since the crystals in the alkali liquor are always in a rolling state, the crystals cannot be agglomerated, and the problem that the crystals block the liquid outlet 12 can be avoided.
In order to avoid the reaction of the gas in the gas bag 21 with the lye, the gas bag 21 contains inert gas which does not react with the lye, or pure air.
In this embodiment, in order to facilitate the gas in the gas bag 21 entering the storage tank 1, an exhaust pipe 23 is installed in the storage tank 1, the exhaust pipe 23 is located between the liquid outlet 12 and the bottom of the storage tank 1, a ventilation pipe 24 is installed between the exhaust pipe 23 and the gas bag 21, and a plurality of gas blowing ports 22 are arranged on the side wall of the exhaust pipe 23 in a penetrating manner. The design ensures that the air blowing openings 22 can be uniformly distributed on the air exhaust pipeline 23, so that the air exhausted from the air blowing openings 22 can move towards a plurality of directions in the storage tank 1, and the distribution range of bubbles is enlarged.
As shown in fig. 3, preferably, the air outlets 22 form a first array and a second array, the first array is located at the bottom of the air exhaust pipe 23, that is, the air outlets 22 in the first array exhaust high-pressure air toward the bottom of the storage tank 1, so that the air outlets 22 in the first array are more aimed at crystallization at the bottom of the storage tank 1, and the crystallization at the bottom of the storage tank 1 is prevented from suffering from stacking problem. The second array is located at a side of the exhaust duct 23 facing the inner wall of the storage tank 1, which causes the gas exhausted from the gas blowing ports 22 in the second array to be exhausted toward the inner wall of the storage tank 1, preventing the phenomenon that crystals adhere to the inner wall of the storage tank 1.
For easy installation of the exhaust duct 23, the outer contour shape of said exhaust duct 23 is identical to the inner contour shape of the storage tank 1. In order to support the exhaust pipe 23 conveniently, a plurality of supporting frames are arranged between the inner wall of the storage tank 1 and the exhaust pipe 23.
The internal profile of the existing lye storage tank is generally cylindrical or circular truncated cone, so the internal profile of the existing lye storage tank is generally cylindrical or circular truncated cone. The exhaust duct 23 is annular in shape in order to facilitate the installation of the exhaust duct 23.
As shown in fig. 3, the high pressure gas discharged from the gas blowing ports 22 can agitate the crystals accumulated in the central area of the bottom of the storage tank 1 due to the large volume of the storage tank 1, and the gas blowing ports 22 in the first array are inclined toward the center of the gas discharge pipe 23. This design allows the high pressure gas exiting the gas blow port 22 to move towards the central area of the bottom of the tank, thereby allowing the high pressure gas to agitate a greater range of lye. Further, the axis of the air blowing openings 22 in the first array forms an angle of 45 ° with the horizontal plane. In this embodiment, the outer contour of the air blowing port 22 is circular, and the centers of a plurality of circles are located on a straight line, which is the axis of the air blowing port 22. Through a plurality of tests, when the axis of the air outlet 22 extends obliquely downwards and has an included angle of 45 degrees with the horizontal plane, the coverage range of the high-pressure air discharged from the air outlet is wider.
As shown in fig. 4, the exhaust duct 23 includes a branch pipe 231 cross-connected, the exhaust duct 23 is disposed around the branch pipe 231, and the exhaust duct 23 communicates with the branch pipe 231, and the bottom of the branch pipe 231 is also provided with an air blowing port 22. The purpose of this design is to enable the high pressure gas exiting the blow ports 22 to cover a greater range.
When the air pressure of the air bag 21 is too low, the alkali liquor in the storage tank 1 enters the exhaust pipeline 23 through the air blowing opening 22, and crystallization in the alkali liquor is prevented from entering the exhaust pipeline 23 along with the alkali liquor, so that the air blowing opening 22 comprises an air inlet cavity 221 and an air outlet cavity 222 which are communicated, one end of the air inlet cavity 221 away from the air outlet cavity 222 is connected with the inner wall of the exhaust pipeline 23, and a filter screen 223 is arranged at one end of the air outlet cavity 222 away from the air inlet cavity 221. The filter mesh 223 functions to block the crystal from entering the inside of the exhaust duct 23.
In order to avoid that the alkali liquor enters the exhaust pipe 23 when the pressure of the air bag 21 is insufficient, as shown in fig. 5, the air outlet cavity 222 is funnel-shaped, the air inlet cavity 221 is cylindrical, an elastic floating ball 224 is arranged in the air outlet cavity 222, one end of the air outlet cavity 222 with a smaller area is connected with the air inlet cavity 221, and the diameter of the elastic floating ball 224 is larger than that of the bottom surface of the air inlet cavity 221. Due to the presence of the filter mesh 223, the elastic floating ball 224 can only move in the air outlet cavity 222. When the air pressure of the air bag 21 is reduced, the air discharged from the air blowing port 22 is gradually reduced, and the elastic floating ball 224 is pushed by the alkali liquor to move towards the end of the air inlet cavity 221 under the action of the water pressure. The elastic floating ball 224 in the scheme has elasticity, the inner contour of the air inlet cavity 221 is a cylinder, and the elastic floating ball 224 blocks the end part of the air inlet cavity 221 under the pushing of alkali liquor, so that the alkali liquor is prevented from entering the exhaust pipeline 23 through the air blowing port 22. When the air pressure of the air bag 21 is restored, the high-pressure air pushes the elastic floating ball 224 away from the end of the air inlet cavity 221, so that the high-pressure air can be injected into the alkali liquor.
As shown in fig. 6, preferably, the elastic floating ball 224 includes a hollow sealing ball 2241, an elastic layer 2242, and a corrosion resistant layer 2243, and the sealing ball 2241, the elastic layer 2242, and the corrosion resistant layer 2243 are sequentially arranged from inside to outside. The hollow sealing ball 2241 makes the elastic floating ball 224 lighter and can move along with the alkali liquor. The purpose of resilient layer 2242 is to ensure that resilient ball 224 may deform slightly. The anti-corrosion layer 2243 is used for assisting the elastic floating ball 224 to resist corrosion of the alkali liquor.
To facilitate the installation of the filter mesh 223, an end of the air outlet cavity 222 away from the air inlet cavity 221 is provided with an internal thread, and an external thread is provided on the circumference of the filter mesh 223, and the filter mesh 223 is in threaded connection with the air outlet cavity 222.
In this embodiment, the high-pressure gas discharged from the gas outlet 22 may be discharged to the outside through the liquid inlet 11, and an additional gas discharging mechanism may be installed at the top of the storage tank 1.
In summary, the scheme has the following beneficial effects: firstly, increased purge mechanism 2 on the basis of original holding vessel 1, compressed gas in the air pocket 21 enters into holding vessel 1 through blow port 22, and gas when moving in alkali lye can drive the crystallization that separates out from alkali lye, has reduced the production of deposit, also makes the deposit unable pile up the caking to the frequency of clearance holding vessel 1 has been reduced, the cost of labor has been reduced. Secondly, in order to prevent alkali liquor and crystals precipitated in the alkali liquor from entering the exhaust pipeline 23, a filter screen 223 and an elastic floating ball 224 are introduced in the scheme.
Example 2:
