[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0023] Please refer to Figure 1 , Figure 1 The utility model provides a washing device for zirconium silicate micropowder production.

[0024] A washing device for zirconium silicate micropowder production comprises a tank 101 and a tank 102 located below the tank 101, a first pipe 103 directly connecting the bottom of the tank 101 with the top of the tank 102, a perforated plate 104 with evenly distributed holes is arranged in the tank 101, the perforated plate 104 divides the tank 101 into an upper chamber 105 and a lower chamber 106, the lower chamber 106 is connected to the inner chamber of the tank 102 through the first pipe 103, a filter cloth 107 is covered on the perforated plate 104, a flow equalizing plate 108 is arranged in the upper chamber 105, a washing water pipe 109 is located above the center of the flow equalizing plate 108, a second pipe 110 is connected to the upper part of the tank 102, a vacuum pump 111 is connected to the second pipe 110, and a third pipe 112 is connected to the bottom of the tank 102.

[0025] The trough 101 and the tank 102 are each fixed to the ground by a support column (not shown in the figure), the orifice plate 104 is connected to the wall of the trough 101, the flow equalizing plate 108 is also connected to the wall of the trough 101, and the third pipe 112 is used to discharge waste water.

[0026] Before washing the zirconium silicate, the zirconium silicate is placed on the filter cloth 107, and then the flow equalizing plate 108 is installed. Finally, the washing water pipe 109 is placed above the center of the flow equalizing plate 108, and then the washing water is turned on, and the vacuum pump 111 is turned on. The washing water is sucked by the vacuum pump 111 into the tank 102 to wash the zirconium silicate.

[0027] Since the water flowing out of the washing water pipe 109 can be controlled by the valve switch, the uniformity of the combination of water and zirconium silicate is good, and the washing water flows evenly through the flow equalizer 108, so that the amount of washing water of zirconium silicate at each position is the same, the friction force is very small and basically negligible, the microstructure of zirconium silicate is not affected, and the specific surface area does not change significantly. During the washing process, there is no loss of zirconium silicate, and the labor intensity is low.

[0028] Those skilled in the art should know that, in the present invention, the number of layers of the filter cloth 107 is set as required and can be selected according to the actual particle size of zirconium silicate.

[0029] Those skilled in the art should be aware that, in the present invention, the current balancing plate 108 can be connected by setting a hook on the edge of the current balancing plate 108 and a ring on the groove wall of the groove 101, or by setting a groove on the bottom edge of the current balancing plate 108 and a protrusion on the groove wall of the groove 101. No special limitation is made here, as long as the connection is detachable.

[0030] In one or more embodiments of the present invention, please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a flow equalizing plate 108 provided by the utility model, and flow equalizing holes 113 are equidistantly provided on the flow equalizing plate 108.

[0031] In order to make the flow rate of the washing water in each flow balancing hole 113 the same, the farther the flow balancing hole 113 is from the vertical center axis of the flow balancing plate 108, the larger the aperture of the flow balancing hole 113.

[0032] In order to control the specific surface area of ​​zirconium silicate to remain unchanged, the distance between the bottom surface of the flow equalizing plate 108 and the top surface of the zirconium silicate before washing is 3-10 cm.

[0033] In one or more embodiments of the present invention, the distance between the upper surface of the flow equalizing plate 108 and the water outlet of the washing water pipe 109 is 5 mm-10 mm.

[0034] In one or more embodiments of the present invention, the flow balancing hole 113 located at a position perpendicular to the central axis of the flow balancing plate 108 has a hole diameter of 1-10 mm.

[0035] To reduce the amount of washing water, please refer to Figure 1In one or more embodiments of the utility model, a circulation pump 114 and a regeneration device 115 are installed on the third pipe 112. Since the impurities contained in the wastewater after washing with washing water are sulfate (from the pre-washing process of zirconium silicate), the regeneration device 115 adopts a chemical precipitation device (by adding a solution that can react with sulfate to generate a precipitate, such as a barium chloride solution), or an ion exchange regeneration device, or an adsorption regeneration device. There is no special limitation here, as long as the washing wastewater can be regenerated and used as washing water again.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
