Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, and in particular to automatic filtering and dehydrating equipment for high-purity copper hydroxide. Background Art

[0002] Copper hydroxide is an inorganic substance with the chemical formula Cu(OH)2. The dry powder appears as blue powder or crystals. It is often used as an analytical reagent, catalyst, mordant, pigment, feed additive, paper dye, swimming pool disinfectant, etc. Since copper hydroxide is insoluble in water, copper hydroxide can be obtained by filtering copper salt and alkali reaction. Therefore, the filtration of copper hydroxide reaction solution is an important process for preparing copper hydroxide, which greatly affects the preparation efficiency of high-purity copper hydroxide. Most of the existing filtering equipment adopts the filter mesh filtering method. After the filter mesh has been working for a period of time, it will be covered with copper hydroxide solids. The filter mesh cannot be used anymore and needs to be replaced. This results in the need to stop the filtering work when the filter mesh is replaced, which affects the preparation efficiency of high-purity copper hydroxide. Therefore, it is necessary to invent a high-purity copper hydroxide automatic filtration and dehydration equipment, which can replace the filter mesh without stopping the machine to improve the filtration efficiency of high-purity copper hydroxide.

[0051] The working principle of this embodiment is as follows:

[0052] 1. Filtering work under normal circumstances:

[0053] In general, if Figure 2-Figure 4 and Figure 10-12 As shown, the flip plates 502 on both sides remain vertical, the sealing movable plate 703 is in place, the sealing plate 704 is flipped downward to form an opening, the linkage plate 709 is located in the linkage plate opening, the fixing hole 3021 of the lower barrel 302 is located above the fixing clamping rod 101, the pull-out frame 707 is located in the lower barrel 302 and the fitting opening 7072 is located directly above the fitting block 7091, the ball plug 803 blocks the guide tube 801, the compression spring of the reset plate 710 is in a free state, the push block 7071 is located in front of the corresponding reset rod 3022, and the main filter 4 is located in the pull-out frame 707;

[0054] The liquid to be filtered enters the liquid inlet barrel 2 from the liquid inlet pipe 201, and then enters the main filter barrel 3 from the liquid inlet barrel 2 through the opening of the sealing plate 704. Subsequently, the liquid to be filtered passes through the main filter screen 4, and the copper hydroxide solid remains on the main filter screen 4. The filtrate flows into the waste liquid barrel 6 and flows out from the liquid outlet pipe 601.

[0055] 2. Replace the main filter 4 and auxiliary filtering work without stopping the machine:

[0056] When the main filter screen 4 is covered with copper hydroxide solids and can no longer perform filtering work, the filtrate no longer flows through the main filter screen 4, and the liquid to be filtered in the liquid inlet barrel 2 accumulates, the extrusion cylinder 701 is started, and the extrusion plate 702 pushes the liquid to be filtered in the liquid inlet barrel 2 to move downward, and the liquid to be filtered pushes the sealing movable frame 703 downward (the sealing movable frame 703 moves to the bottom of the auxiliary outlet), and the sealing movable frame 703 pushes the main filter barrel 3 downward, and the connecting block 705 moves upward relative to the upper barrel 301 in the avoidance chute, and the connecting rod 706 rotates , driving the sealing plate 704 to flip upward and combine into a complete horizontal sealing plate; at the same time, the flip plates 502 on both sides flip outward under the drive of the limit rod 7031, the auxiliary filter barrel 501 is connected with the liquid inlet barrel 2, and the accumulated to-be-filtered liquid above the horizontal sealing plate in the liquid inlet barrel 2 enters the auxiliary filter barrel 501 through the auxiliary outlet, and the auxiliary filtering work begins. The to-be-filtered liquid passes through the auxiliary filter screen 504, and the copper hydroxide solid remains on the auxiliary filter screen 504. The filtrate flows into the waste liquid barrel 6 and flows out from the liquid outlet pipe 601;

[0057] As the main filter barrel 3 moves downward, the pull-out frame 707 and the main filter screen 4 start to move downward accordingly, and the fixing hole 3021 of the lower barrel 302 is aligned with the fixing clamping rod 101 on the support frame 1. The fixing clamping rod 101 is first pushed outward and then extends into the corresponding fixing hole 3021 under the restoring action of the compression spring, so that the entire main filter barrel 3 is fixed on the support frame 1; and the engaging block 7091 of the linkage plate 709 enters the engaging opening 7072 of the pull-out frame 707, and the linkage plate 709 is relatively fixed with the drawer frame 707; at the same time, the bottom end of the guide tube 801 moves downward in the guide tube 802, the push rod on the ball plug 803 is blocked by the blocking rod 804, the ball plug 803 is separated from the outlet of the guide tube 801, the guide tube 801 and the guide tube 802 are connected, and the accumulated to-be-filtered liquid below the horizontal sealing plate in the main filter barrel 3 flows from the guide tube 801 into the guide tube 802, and then flows from the return pipe 805 into the liquid inlet pipe 201, waiting for the next filtering work;

[0058] After the linkage plate 709 and the pull-out frame 707 are relatively fixed, the electric push rod 708 is started to drive the linkage plate 709 to move forward, and the linkage plate 709 pulls the pull-out frame 707 out of the linkage plate opening, and the staff takes out the used main filter screen 4 and replaces it with a new main filter screen 4; it is worth noting that in the process of the pull-out frame 707 moving outward, the reset rods 3022 located in the middle and front parts will be pushed outward by the push blocks 7071 located behind them, and these reset rods 3022 will push the fixed clamping rods 101 in the corresponding fixing holes 3021 out of the fixing holes 3021, but the reset rods 3022 located at the rear will not be pushed by the push blocks 7071, so the fixed clamping rods 101 located at the rear are always located in the corresponding fixing holes 3021, which makes the main filter barrel 3 always fixed on the support frame 1 when the pull-out frame 707 moves outward;

[0059] After the main filter screen 4 is replaced, the electric push rod 708 drives the linkage plate 709 to move backward, and the linkage plate 709 pushes the pull-out frame 707 backward. In the process of the pull-out frame 707 moving backward, the reset rod 3022 is pushed outward by the push block, so that the fixed card rod 101 moves outward, but the fixed card rod 101 located at the rearmost will always be located in the corresponding fixing hole 3021 until the pull-out frame 707 contacts the reset plate 710 and continues to move backward a short distance. At this time, the compression spring on the reset plate 710 is compressed, and all the push blocks 7071 push their corresponding reset rods 3022 outward, and the reset rods 3022 push all the fixed card rods 101 out of the corresponding fixing holes 3021. The main filter barrel 3 loses the limiting effect of the fixed card rod 101 and will move upward under the reset effect of the compression spring, and the sealing movable frame 703 and the pull-out frame 707 move upward accordingly, and the embedded block 7091 disengages from the embedded When the opening 7072 is closed, the pull-out frame 707 loses the limiting effect of the engaging block 7091, and the compression spring on the reset plate 710 rebounds, so that the reset plate 710 drives the pull-out frame 707 to move forward a short distance in the lower barrel 302, and the push block 7071 returns to the front of the corresponding reset rod 3022; and the sealing movable frame 703 moves upward, the flip plate 502 flips to a vertical state under the reset effect of the compression spring, and the connecting block 705 moves downward relative to the upper barrel 301 in the avoidance slide groove, and the connecting rod 706 rotates, driving the sealing plate 704 to flip downward and form an opening; at the same time, the main filter barrel 3 moves upward to drive the guide tube 801 to move upward, the push rod disengages from the blocking rod 804, and the ball plug 803 blocks the outlet of the guide tube 801 again; finally, the electric push rod 708 drives the linkage plate 709 to move forward a short distance, and the entire automatic filtering and dehydration equipment returns to the filtering working state under normal circumstances;

[0060] The staff pulls out the pull-out plate 503 and replaces the used auxiliary filter 504 with a new auxiliary filter 504, and the auxiliary filtering work is completed.
