[0022] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0023] The core of the present utility model is to provide a nano-slurry dechlorination device, which can achieve efficient dechlorination.

[0024] In order to enable those skilled in the art to better understand the technical solution provided by the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Specifically, please refer to Figure 1 , a nano-slurry dechlorination device provided by the present utility model includes a storage tank 100, a feed pipe 300, and a filter barrel 400.

[0026] The storage tank 100 serves as a container for providing a dechlorination operation space and accommodating the dechlorinated slurry. The storage tank 100 has a hollow cavity inside, and a discharge port is provided on the storage tank 100. The storage tank 100 can be a cylindrical barrel with both upper and lower ends being flat surfaces, or a storage tank 100 with a cylindrical top and a conical bottom. A cover body can also be provided on the top of the storage tank 100. Of course, the shape and structure of the storage tank 100 can also adopt other forms, and can be specifically selected adaptively according to actual needs.

[0027] One end of the feed pipe 300 is a feed port, and the other end penetrates the storage tank 100 and is inserted into the hollow cavity. The slurry is transported from the outside of the storage tank 100 to the inside of the storage tank 100 through the feed pipe 300. One end of the feed pipe 300 can be used to communicate with the discharge port of the sand mill in the previous process. After the slurry is ground by the sand mill, it enters the storage tank 100 in this solution. After the chloride ions are filtered out by the filter barrel 400, it is discharged from the discharge port of the storage tank 100 and then returned to the feed port of the sand mill.

[0028] The filter barrel 400 is communicated with the other end port of the feed pipe 300. The barrel wall of the filter barrel 400 encloses a closed cavity. A number of discharge holes are provided on the filter barrel 400, and a dechlorination layer for adsorbing chloride ions is laid on the inner wall of the filter barrel 400. After the slurry fully contacts the dechlorination layer to remove chloride ions, it is discharged from the discharge holes into the hollow cavity of the storage tank 100.

[0029] A chlorine removal device for nano slurry provided by the utility model, the slurry enters the filter barrel 400 through the feed pipe 300, and then is discharged through the discharge holes on the filter barrel 400 into the hollow cavity of the storage tank 100. Since a chlorine removal layer is laid on the inner wall of the filter barrel 400, the chlorine removal layer can be in full contact with the slurry to adsorb the chloride ions in the slurry, and the slurry after removing the chloride ions is stored in the storage tank 100. By using the chlorine removal device for nano slurry in this solution, efficient chlorine removal can be achieved without adding other chemical reagents.

[0030] In addition, compared with adding a dispersant to the slurry after grinding in the prior art, and separating the precipitated chlorine after sedimentation and solidification for a period of time, this method consumes more preparation time. In this application, one end of the feed pipe 300 can be connected to the discharge port of the upper sand mill, the slurry enters the chlorine removal device for nano slurry in this solution after being ground by the sand mill, the discharge port of the chlorine removal device for nano slurry is connected to the feed port of the sand mill, and the slurry after chlorine removal returns to the sand mill again. The chlorine removal device for nano slurry can be used simultaneously with the sand mill. The form of separately removing chlorine from the existing slurry is transformed into a chlorine removal form integrated with the grinding process of the sand mill, which reduces the energy consumption to a certain extent and saves the slurry preparation time.

[0031] This solution also includes a bracket 200 for supporting the storage tank 100. The bracket 200 can be a fixed bracket, and the bottom of the fixed bracket is stably placed on the ground by its own gravity or fixedly connected to the ground by bolts. The bracket 200 can also be a movable bracket, and a moving wheel is arranged at the bottom of the bracket 200, so that the chlorine removal device for nano slurry can be moved to any designated position.

[0032] In order to facilitate adjusting the setting angle of the storage tank 100, the bracket 200 and the storage tank 100 are rotatably connected. Specifically, the bracket 200 is connected to the storage tank 100 through a rotating mechanism, which can be applicable to the angle adjustment when the storage tank 100 needs to be cleaned or components need to be replaced.

[0033] In a specific embodiment, a switch valve 500 is arranged at the discharge port of the storage tank 100 to control whether the slurry flows out. The switch valve 500 can be a manual valve or an electromagnetic valve, and can be specifically selected adaptively according to actual applications.

[0034] In order to improve the structural strength, the filter barrel 400 and the feed pipe 300 are of an integral structure. Of course, a split structure can also be adopted, and the filter barrel 400 and the feed pipe 300 are clamped together through a clamping mechanism.

[0035] In a specific embodiment, the filter barrel 400 includes a top barrel wall, a side barrel wall and a bottom barrel wall. The top barrel wall and the side barrel wall form part of the storage tank 100, the bottom barrel wall is hermetically connected to the side wall of the storage tank 100, and a plurality of discharge holes are arranged on the bottom barrel wall.

[0036] In one case, the filter barrel 400 can be arranged separately from the inner wall of the storage tank 100, and the shape of the filter barrel 400 can be a cylindrical structure as shown in Figure 1 the figure, and can also be adaptively selected according to the actual situation. In another case, the filter barrel 400 can also directly use the top barrel wall and the side barrel wall of the filter barrel 400 as part of the storage tank 100. When the top barrel wall and the side barrel wall of the filter barrel 400 are used as part of the storage tank 100, all the improvements in all the specific embodiments of this case are carried out on the bottom barrel wall, and processing and transformation are carried out on the bottom barrel wall in actual production.

[0037] In a specific embodiment, the dechlorination layer is a resin layer. The principle of using the resin layer to adsorb chloride ions is to utilize the ion exchange performance of the resin to exchange the chloride ions in the slurry with the sodium ions on the resin, so as to achieve the effect of removing chlorine. It has been proved by experiments that the device dechlorinates the slurry with a particle size of 400 nm and a barium titanate solid content of more than 50%, and the dechlorination effect reaches the expectation, and far exceeds the dechlorination effect of using a dispersant in the prior art.

[0038] Of course, the filter barrel 400 can also be made of resin material and has the same adsorption principle.

It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.
