Description

Technical Field

[0001] The invention mainly relates to the field of material storage, and in particular to an activated matrix buffer device of a nitrate adsorption resin. Background Art

[0002] During the preparation process of the nitrate adsorption resin, a pre-prepared monomer phase needs to be added to an aqueous phase, polymerized into an activated matrix under an environment of 70 to 100° C., cooled to room temperature, cleaned and dried, wherein the monomer phase needs to be calculated by weight, and 679 to 680 parts of styrene, 48 to 49 parts of a diene or triene crosslinking agent and an initiator are mixed, and the aqueous phase needs to be calculated by weight, and 990 to 1010 parts of deionized water, 32 to 33 parts of sodium chloride and a dispersant are mixed and heated to 70 to 100° C.

[0003] The monomer phase is added to the water phase, maintained at 82°C for 4 hours, then heated to 88°C and maintained for 1.5 hours to polymerize into an activated matrix, which is then cleaned and dried to obtain small balls of 300 to 1000 μm. Usually, the monomer phase and the water phase are pre-placed in a reactor for activation treatment, and the polymerized activated matrix and excess reaction solution are subsequently discharged for cleaning and drying. The polymerization of the activated matrix takes a long time, and if the production capacity is to be expanded, multiple reactors need to be equipped, considering that only certain requirements are made on temperature during the polymerization of the activated matrix.

[0063] The lifting motor 31 drives the screw rod 32 to rotate on the guide frame 3, and cooperates with the slide rod 33 to complete the working position adjustment of the slide seat 34 on the guide frame 3. The slide seat 34 cooperates with the truss 4 to change the working position of the mounting frame 5 above the tank body 2, and completes the working height adjustment of the hollow rotating shaft 6 and the ultrafiltration membrane tube 91 in the inner tank 22.

[0064] The driving motor and the flat gear 52 drive the flat gear ring 61 to rotate, completing the rotation adjustment of the hollow shaft 6 and the ultrafiltration membrane tube 91 in the inner tank 22. The water pump 53 and the water extraction pipe 54 cooperate to extract the excess water or the mixed solution of the monomer phase and the water phase in the inner tank 22 through the hollow shaft 6 and the ultrafiltration membrane tube 91.

[0065] In this embodiment, Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the top of the hollow shaft 6 is movably connected to the middle of the mounting frame 5, a flat gear ring 61 is clamped on the top of the hollow shaft 6, the left end of the flat gear ring 61 is meshed with the right side of the flat gear 52, a docking tube 62 is movably nested on the top of the hollow shaft 6, the outer side of the docking tube 62 is movably connected to the top of the mounting frame 5, and the top water outlet of the docking tube 62 is fixedly connected to the water inlet of the water pump 54.

[0066] During the rotation of the hollow shaft 6 , the water pump 53 cooperates with the water pumping pipe 54 through the docking pipe 62 to complete the water pumping process from the inner tank 22 .

[0067] In this embodiment, Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, a through hole is fixedly provided from the bottom to the top of the hollow shaft 6 , and the bottom of the hollow shaft 6 extends to the inner side of the inner container 22 .

[0068] The through hole structure of the hollow rotating shaft 6 facilitates the water pump 53 to extract water or mixed solution, and the through hole is used in conjunction with the docking sleeve 9 on the upper part of the ultrafiltration membrane tube 91.

[0069] In this embodiment, Figure 7 and Fig. 9 As shown, the variable pitch stirring structure includes a sleeve 7, the top of the sleeve 7 is fixedly connected to the bottom of the hollow rotating shaft 6, the bottom of the sleeve 7 is movably connected with four upper connecting rods 71 ​​at equal intervals, the bottom of the upper connecting rod 71 is movably connected with a counterweight seat 72, the bottom of the counterweight seat 72 is movably connected with a lower connecting rod 73, the bottom of the lower connecting rod 73 is movably connected with a positioning ring 74, and the middle part of the positioning ring 74 is clamped with the outer side of the positioning plate 92.

[0070] During the rotation of the hollow shaft 6, the upper connecting rod 71, the counterweight seat 72, the lower connecting rod 73 and the positioning ring 74 cooperate to rotate. When the counterweight seat 72 rotates, it moves outward along the radial direction of the hollow shaft 6.

[0071] During the drainage operation, the working distance between the positioning ring 74 and the sleeve 7 is variable, the ultrafiltration membrane tube 91 will bend between the sleeve 7 and the positioning ring 74, and deformation and contact friction will occur between multiple ultrafiltration membrane tubes 91, so as to avoid the polymerized 300μm~1000μm activated matrix covering the surface of the ultrafiltration membrane tube 91 and affecting the pumping operation efficiency. Combined with the adjustable working height of the hollow rotating shaft 6, the drainage operation efficiency of the equipment is further improved, and the subsequent cleaning and drying of the activated matrix is ​​convenient.

The upper connecting rod 71, the lower connecting rod 73 and the counterweight seat 72 stir and clean the activated matrix balls. At the same time, the ultrafiltration membrane tube 91 and the hollow shaft 6 cooperate to pump water.

[0073] At the end of the drainage operation, it is possible to consider raising the ambient temperature in the inner tank 22 and turning over the activated matrix balls in the inner tank 22 for drainage, so as to further reduce the dehydration time of the activated matrix balls and improve the production efficiency of the activated matrix.

[0075] In order to prevent the activated matrix from squeezing out and causing the working distance between the positioning ring 74 and the sleeve 7 to be too small, a leaf spring 8 is provided to complete the expansion processing of the upper connecting rod 71 and the lower connecting rod 73 outside the counterweight seat 72.

[0076] In this embodiment, the ultrafiltration membrane tube 91 is spirally cross-arranged between the docking sleeve 9 and the positioning plate 92 .

[0077] In order to improve the efficiency of the hollow shaft 6 rotating to prevent the activated matrix from adhering to the outside of the ultrafiltration membrane tube 91 , a spiral cross setting can be adopted to increase the contact area between adjacent ultrafiltration membrane tubes 91 .

[0078] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
