Embodiment Construction
[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0012] Such as figure 1 , figure 2 , image 3 As shown, the lye distribution device for caustic soda and caustic soda concentration includes: feed pipe 1, feed pipe 1 extends downward into the distribution box 2, and the distribution box 2 is located in a closed feed box In the body 3, overflow ports 4 of the same size are respectively provided on both sides of the material distribution box 2, and the overflow ports 4 on each side are provided with a diversion groove 19 for guiding the lye into the side collecting box . The effect of diversion groove 19 is to be able to prevent lye from flowing along the outer wall of material distribution box 2. The bottom in the feed box body 3 below the distribution box 2 is provided with two collection boxes with open tops and separated from each other, which are respectively the first colle...

The invention discloses an alkali solution distribution device for concentrating caustic soda and flaky caustic soda. The alkali solution distribution device is simple to operate and reliable to use and comprises a feed pipe downwards stretching into a distribution box located in a sealed feed box body, wherein overflow holes are respectively formed in two sides of the distribution box, two collection boxes separated from one another and provided with openings in the tops are arranged in the feed box body below the distribution box, a discharge hole is formed in the bottom of each of the two collection boxes, two sides of the distribution box are movably supported in the feed box body, one side of the distribution box is fixedly connected with a transverse rod, and when the distribution box is in a vertical state, alkali solution in the distribution box can uniformly overflow respectively from the overflow holes in two sides of the distribution box and uniformly flow into the two collection boxes; the transverse rod can be rotated to drive the top of the distribution box to respectively incline towards the two collection boxes below the distribution box so as to enable the alkali solution in the distribution box to overflow from the overflow hole in the corresponding side and flow into the corresponding collection box; a rotating driving device and a locking device for locking the transverse rod are connected to the transverse rod.
Description
technical field [0001] The invention relates to the field of solid alkali production of caustic soda and caustic soda, in particular to an alkali liquor distribution device in the process of concentrating caustic soda and caustic soda. Background technique [0002] In the solid alkali production process of caustic soda and flake soda, it is necessary to uniformly transport the lye with a concentration of more than 99% and a temperature of about 400°C to each collection box. The structure of the traditional distribution device for distributing lye includes: Feeding pipes are respectively arranged on the material boxes, and a regulating valve is arranged on each feeding pipe. The disadvantage of the above-mentioned distribution device is that: when the temperature of the lye is as high as about 400°C, the control valve is easily damaged, and frequent replacement of the control valve is not only time-consuming and laborious, but also greatly increases the production cost of alk...
