[0023] Please refer to Figure 1 , Figure 1 The utility model provides an acid mist-proof zirconium silicate acid washing tank.

[0024] The invention discloses an acid mist-proof zirconium silicate pickling tank, comprising an upper tank 101, a lower tank 102 integrally connected with the upper tank 101, a feed pipe 107 and an acid liquid inlet pipe 108, wherein the upper tank 101 is covered with a tank cover 103, a zirconium silicate discharge pipe 104 is provided at the bottom of the lower tank 102, an acid liquid circulation pipe 105 is connected to the lower tank 102, a circulation pump 106 is installed on the acid liquid circulation pipe 105, the other end of the acid liquid circulation pipe 105 is connected to the acid liquid inlet pipe 108, the feed pipe 107 and the acid liquid inlet pipe 108 respectively pass through the tank cover 103 (the tank cover 103 is provided with holes for matching the feed pipe 107 and the acid liquid inlet pipe 108 to pass through), the outlet of the feed pipe 107 is located in a cavity formed by the upper tank 101 and the tank cover 103, and the outlet of the acid liquid inlet pipe 108 is located in the cavity formed by the upper tank 101 and the tank cover 103.

[0025] The upper trough 101 is square and the lower trough 102 is in the shape of a chamfered pyramid. The upper trough 101 and the lower trough 102 are supported by supporting feet connected to the lower trough 102. The supporting feet are located on the bottom surface. A filter screen is installed at the entrance of the acid circulation pipe 105. The aperture of the filter screen is selected according to the particle size of zirconium silicate. The function of the filter screen is to prevent zirconium silicate from entering the acid circulation pipe 105.

[0026] By setting up the acid circulation pipe 105, the circulation pump 106 and the acid inlet pipe 108, the zirconium silicate is equivalent to being immersed in the flowing acid solution, so as to carry out pickling and iron removal, realizing the pickling function, and no stirring is used, which reduces energy consumption, and at the same time reduces the volatilization of the acid solution and the formation of acid mist.

[0027] In one or more embodiments of the present invention, a horizontal baffle 109 is installed in the upper tank 101, and the horizontal baffle 109 blocks the acid gas below it. At this time, the feed pipe 107 and the acid liquid inlet pipe 108 both pass through the horizontal baffle 109 (the horizontal baffle 109 is provided with a hole for the feed pipe 107 and the acid liquid inlet pipe 108 to pass through).

[0028] The horizontal baffle 109 can be connected by setting a hook on the edge of the horizontal baffle 109 and a ring on the groove wall of the upper groove 101, or by setting a groove on the bottom edge of the horizontal baffle 109 and a protrusion on the groove wall of the upper groove 101, or by directly welding the horizontal baffle 109 to the groove wall of the upper groove 101, which is not specifically limited here.

[0029] In one or more embodiments of the present invention, please refer to Figure 2 , Figure 2This is a schematic diagram of a horizontal baffle structure of the utility model.

After the liquid distribution holes 110 are provided, the acid liquid from the acid liquid inlet pipe 108 is dispersed into a plurality of tributaries through the liquid distribution holes 110, and flows down from the horizontal baffle 109 to the zirconium silicate to be washed, so that the acid liquid and the zirconium silicate are mixed more evenly and the impurities are removed more thoroughly.

[0030] In one or more embodiments of the present invention, the distance between the upper surface of the horizontal baffle 109 and the outlet of the acid inlet pipe 108 is 2 mm-6 mm to avoid splashing of the acid.
