Description

Technical Field

[0001] The utility model relates to the technical field of mixed-flow crystallization tanks, in particular to a high-efficiency mixed-flow crystallization tank. Background Art

[0002] The crystallization tank is a commonly used device in the chemical industry. For example, the patent with publication number CN220070783U discloses a synthetic crystallization tank, which includes a steel-lined plastic tank body, a plurality of feed flange pipes arranged at the top of the tank body, and a discharge pipe arranged at the bottom of the tank body. In addition, a stirring component is also provided inside the tank body. However, in actual industrial production, the crystallization tank has a large volume and height (for example, the tank body is usually arranged between two floors), and the added liquid cannot be mixed by providing a stirring component. If the material is directly fed from the top of the crystallization tank and then discharged from the bottom of the crystallization tank, it is easy to cause large crystals to appear in the crystallization tank, thereby resulting in poor quality of the crystallized product.

[0020] Example 1

[0021] See also Figure 1 to Figure 2 The utility model provides the following technical solutions: a high-efficiency mixed-flow crystallization tank, which is suitable for mixing materials in a large crystallization tank.

[0022] Specifically, Figure 1 and Figure 2 As shown, a high-efficiency mixed-flow crystallization tank comprises a tank body 1, a liquid outlet pipe 2, a pair of first mixed-flow pipes 3 and a pair of diverter components 4; the tank body 1 comprises a first top end 11 and a second bottom end 12; the pair of diverter components 4 are relatively arranged inside the first top end 11; the first mixed-flow pipe 3 penetrates from the side of the first top end 11 and extends toward the diverter component 4; the first top end 11 is connected to the second bottom end 12; the second bottom end 12 is connected to the liquid outlet pipe 2.

[0023] In this embodiment, a cover body 8 can be further provided on the top of the tank body 1 for sealing so that liquid splashing will not occur in the subsequent mixing stage; a pair of first mixing pipes 3 are respectively connected to the top of the tank body 1, and are both diverted through a diversion component 4 arranged inside the tank body 1. Through the pair of diversion components 4 arranged relatively, the incoming liquid can be fully mixed, thereby avoiding the occurrence of large crystals in the subsequent crystallization process and ensuring the quality of the crystals.

[0024] Specifically, Figure 1 and Figure 2 As shown, the diverter assembly 4 includes a first orifice plate 41 and a second bottom plate 42; both side ends of the first orifice plate 41 are connected to the inner side wall of the first top end 11; the bottom end of the first orifice plate 41 is connected to the inner side wall of the first top end 11 through the second bottom plate 42; the inner side wall of the first top end 11, the first orifice plate 41 and the second bottom plate 42 are surrounded by a feed chamber 5.

[0025] In this embodiment, a pair of first orifice plates 41 are both arc-shaped orifice plates; the convex surfaces of the pair of arc-shaped orifice plates are arranged opposite to each other; thereby, the diversion surface can be expanded and the flow can be mixed efficiently; wherein, the second bottom plate 42 is not provided with a liquid outlet, thereby ensuring that after feeding, the feed liquid is diverted out from the liquid outlet; wherein, in order to avoid clogging, the aperture of the filter hole should be set according to the usage conditions such as crystallization.

[0026] In this embodiment, considering the residual crystals in the diverter assembly 4, the diverter assembly 4 can be configured to be detachable. Specifically, a slot 9 is provided in the top of the trough body 1, and a strap 10 is provided on the top of the first orifice plate 41.
