Description

Technical Field

[0001] The present invention relates to the technical field of waste treatment, and in particular to a method and device for collecting and recycling mercury waste liquid. Background Art

[0002] Mercury is a volatile, toxic heavy metal element. It is the only metal that exists in liquid form at room temperature and pressure. It is silvery white in color, has stable chemical properties, is insoluble in acid or alkali, and can evaporate at room temperature. The sources of mercury in water are mainly due to improper treatment and application of mercury or the production of mercury mines, gold mines, chlor-alkali chemical plants, amalgam recovery of precious metals, non-ferrous metal smelters, pesticide plants, batteries, fluorescent lamps, and thermometers. In addition, pharmaceuticals, cosmetics, hospital laboratories, etc. also discharge a certain amount of mercury-containing wastewater. Mercury-containing pollutants are mainly present in the bottom mud and suspended matter near the sewage outlet.

[0003] In traditional mercury waste liquid treatment, corresponding chemical agents are used to reduce and extract the mercury in the waste liquid to avoid mercury pollution. However, during the process of extracting the mercury and removing it from the corresponding container, there is no corresponding sealing device to seal the mercury. Due to the volatility of mercury itself, mercury easily evaporates when it comes into contact with air, thereby producing toxic gases.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a device for collecting and recycling mercury waste liquid.

[0040] See also Figure 1-Figure 3 A mercury waste liquid collection and resource recycling device includes a collection tank 1, a tank cover 2, a water inlet pipe 3 provided on the outer periphery of the collection tank 1 and a water outlet pipe 4 at the bottom. The inner cavity of the collection tank 1 is provided with a primary filter component 5 and a secondary filter component 6;

[0041] The can cover 2 includes a cover ring 21 and a sealing cover plate 22 sleeved on the inner cavity of the cover ring 21;

[0042] The primary filter assembly 5 includes a sealing plate 51;

[0043] A driving device 7 is installed on the top of the outer periphery of the collecting tank 1, and the driving device 7 drives the sealing cover plate 22 and the sealing plate 51 to rise and fall;

[0044] The secondary filter assembly 6 includes a filter element 61, a fixed sleeve 62 sleeved around the outer periphery of the filter element 61, a locking assembly 8 disposed between the fixed sleeve 62 and the filter element 61, the filter element 61 includes a sleeve 611, a sealing plate 51 is aligned with the top of the sleeve 611, and an unlocking assembly 9 is disposed between the sealing plate 51 and the sleeve 611;

[0045] The driving device 7 drives the sealing plate 51 to move downward so that the sealing plate 51 coincides with the sleeve 611 and enters the inner cavity of the sleeve 611. At this time, the unlocking component 9 contacts the locking component 8 to combine and lock the sealing plate 51 with the filter element 61, and allows the filter element 61 to be separated from the fixing sleeve 62. Then, the driving device 7 drives the top-sealed filter element 61 to move upward and out of the collection tank 1.

[0046] Specifically, after the mercury waste liquid in the inner cavity of the collection tank 1 is filtered, the driving assembly drives the sealing cover plate 22 and the primary filter assembly 5 to move downward, so that the sealing plate 51 contacts the filter element 61. When the sealing plate 51 enters the inner cavity of the filter element 61, the unlocking assembly 9 contacts the locking assembly 8 and unlocks the locking assembly 8. After the locking assembly 8 is unlocked, the sleeve 611 and the fixed sleeve 62 are separated, and the sealing plate 51 and the filter element 61 are locked together. The sealing plate 51 seals the top of the sleeve 611. After the filter element 61 is sealed, the driving device 7 drives the sealing plate 51 to move upward, thereby removing the filter element 61 from the collection tank 1.

[0047] By switching the locking assembly 8 and the unlocking assembly 9, the filter element 61 is locked in the inner cavity of the fixed sleeve 62 by the locking assembly 8 during filtering of the collection tank 1, thereby filtering the mercury reacted and extracted in the inner cavity of the collection tank 1. When the purification and extraction of the mercury waste liquid in the inner cavity of the collection tank 1 is completed, the driving device 7 drives the sealing plate 51 to combine with the filter element 61, so that the unlocking assembly 9 contacts the locking assembly 8 and unlocks the locking assembly 8. The unlocking of the locking assembly 8 separates the filter element 61 from the fixed sleeve 62, and fixes the sealing plate 51 and the filter element 61 by the unlocking assembly 9, thereby sealing the top of the filter element 61, solving the problem that the mercury generated after the purification and extraction of the mercury waste liquid is volatile, and after the mercury is taken out of the reaction container, it comes into contact with the air and volatilizes, thereby generating toxic gas.

[0048] Further, see Figure 2 For the above-mentioned tank cover 2, the cover ring 21 is sleeved on the top of the collection tank 1, and the outer wall of the sealing cover plate 22 is always in contact with the inner wall of the cover ring 21 and the inner wall of the collection tank 1;

[0049] The sealing cover plate 22 fits in contact with the inner wall of the cover ring 21, thereby sealing the inner cavity of the collection tank 1. When the sealing cover plate 22 moves downward through the driving device 7, the outer edge of the sealing cover plate 22 always fits in contact with the inner wall of the collection tank 1, thereby ensuring that the sealing cover plate 22 remains sealed during movement.

[0050] Further, see Figure 2 As for the above-mentioned driving device 7, the driving device 7 includes a servo cylinder 71. Bearing plates 72 are fixedly installed on both sides of the outer periphery of the collection tank 1. The servo cylinder 71 is installed on the top of one of the bearing plates 72. A telescopic rod 73 is fixedly installed on the top of the bearing plate 72. The servo cylinder 71 is fixedly connected to one of the telescopic rods 73. A bearing plate 74 is fixedly installed on the top of the telescopic rod 73. The bearing plate 74 is connected to the sealing cover plate 22 through a support plate fixing rod.

[0051] The servo cylinder 71 drives the telescopic rod 73 to extend or shorten, thereby controlling the lifting of the carrier plate 74, and further controlling the lifting of the sealing cover plate 22 and the first-stage filter assembly 5.

[0052] Further, see Figure 3 For the above-mentioned collecting tank 1, the bottom of the sealing cover plate 22 is rotatably connected to the connecting rod 10 through a bearing. The bottom of the connecting rod 10 is movably connected to the sealing plate 51. A plurality of stirring blades 11 are fixedly installed on the periphery of the connecting rod 10. A servo motor 12 is fixedly installed on the top of the sealing cover plate 22. The output end of the servo motor 12 is fixedly connected to the top of the connecting rod 10.

[0053] The servo motor 12 is started and drives the connecting rod 10 to rotate, thereby driving the stirring blades 11 on the periphery of the connecting rod 10 and the sealing plate 51 at the bottom of the connecting rod 10 to rotate, thereby stirring the inner cavity of the collection tank 1.

[0054] Further, see Figure 3 and Figure 4 For the above-mentioned primary filter assembly 5, the primary filter assembly 5 further includes a filter sleeve 52, the outer wall of the filter sleeve 52 is in contact with the inner wall of the collection tank 1, the inner wall of the filter sleeve 52 is in contact with the outer wall of the sealing plate 51, a plurality of sliding blocks 53 are fixedly provided on the top of the outer wall of the sealing plate 51, and a sliding groove 54 is opened on the inner wall of the filter sleeve 52, and the sliding block 53 is slidably arranged in the inner cavity of the sliding groove 54;

[0055] The filter sleeve 52 is annularly sleeved on the outer periphery of the sealing plate 51, and filter holes are provided at the bottom of the filter sleeve 52, so as to filter out larger impurities generated during the purification of mercury waste liquid above the inner cavity of the collection tank 1, thereby achieving primary filtration, and the centrifugal force generated when the sealing plate 51 rotates moves the impurities on the sealing plate 51 to the inner cavity of the filter sleeve 52, thereby achieving the effect of collecting the impurities.

[0056] Further, see Figure 5 and Figure 6 For the above-mentioned filter element 61, an inclined plate 13 is installed on the top of the fixed sleeve 62. The filter element 61 also includes a filter membrane 612 and a collection chamber 613. The filter membrane 612 is fixedly installed above the inner cavity of the sleeve 611. A limiting groove 614 is defined at the bottom of the sleeve 611. A limiting plate 615 is fixedly installed on the top of the collection chamber 613. The limiting plate 615 is slidably arranged in the inner cavity of the limiting groove 614. A plurality of first springs 616 are fixedly installed on the top of the limiting plate 615.

[0057] The inclined plate 13 is arranged in a ring shape, and its side close to the inner side of the ring is arranged as an inclined surface, so that when the mercury waste liquid after the first-stage filtration flows downward through the filter sleeve 52, some impurities pass through the inclined surface on the inclined plate 13, so that the impurities and mercury waste liquid move into the inner cavity of the filter element 61, thereby preventing some impurities from being left on the fixed sleeve 62. The filter membrane 612 is arranged in a conical shape above the inner cavity of the sleeve 611, and the filter membrane 612 can be arranged as a reverse osmosis membrane, a nanofiltration membrane 612, etc. The inner cavity of the collection chamber 613 can be used to place adsorbents such as activated carbon to adsorb trace amounts of mercury and other harmful elements contained in the mercury waste liquid after the second filtration. The bottom of the collection chamber 613 is provided with filter holes, so that the mercury waste liquid after the third-stage filtration can flow out.

[0058] Further, see Figure 8 and Figure 9 For the locking assembly 8, the locking assembly 8 includes a first clamping block 81, a plurality of first built-in grooves 83 are formed on the inner wall of the fixing sleeve 62, the first clamping block 81 is slidably arranged in the inner cavity of the first built-in groove 83, a second spring 82 is fixedly installed on one end of the first clamping block 81 close to the first built-in groove 83, a plurality of clamping holes 14 are formed on the inner wall of the sleeve 611, and the first clamping block 81 is sleeved in the inner cavity of the clamping hole 14;

[0059] By means of the sleeve connection between the first clamping block 81 and the clamping hole 14, when the first clamping block 81 is located in the inner cavity of the clamping hole 14, the locking assembly 8 fixes the filter element 61 in the inner cavity of the fixing sleeve 62, thereby achieving the effect of secondary filtration of the mercury waste liquid. When the first clamping block 81 is received in the inner cavity of the first built-in groove 83, the locking assembly 8 no longer restricts the filter element 61, thereby facilitating the removal of the filter element 61 from the fixing sleeve 62.

[0060] Further, see Figure 7 Regarding the unlocking assembly 9, the unlocking assembly 9 includes a second clamping block 91. A plurality of second built-in grooves 93 are formed on the outer bottom of the sealing plate 51. The second clamping block 91 is slidably arranged in the inner cavity of the second built-in groove 93. A third spring 92 is fixedly installed on one end of the second clamping block 91 close to the second built-in groove 93. The second clamping block 91 is sleeved in the inner cavity of the clamping hole 14.

[0061] When the sealing plate 51 enters the inner cavity of the sleeve 611, the second clamping block 91 is squeezed by the sleeve 611, so that the second clamping block 91 is accommodated in the inner cavity of the second built-in groove 93, and the third spring 92 is in an extruded state. When the sealing plate 51 enters the inner cavity of the sleeve 611 to a certain extent and the second built-in groove 93 coincides with the clamping hole 14, the second clamping block 91 is not squeezed, so that the third spring 92 restores its elasticity and drives the clamping block to move into the clamping hole 14, thereby pushing the first clamping block 81 in the clamping hole 14 toward the inner cavity of the first built-in groove 83, so that the first clamping block 81 is separated from the clamping hole 14, so that the filter element 61 and the fixing sleeve 62 can move, and the sealing plate 51 and the filter element 61 are fixed.

[0062] Further, see Figure 10 For the above-mentioned collection tank 1, a vibration assembly 15 is provided at the bottom of the filter sleeve 52, and the filter sleeve 52 is powered by the vibration assembly 15 and the collection bin 613. The vibration assembly 15 includes a plurality of elastic telescopic plates 151. A plurality of chute 152 is provided on the inner wall of the collection tank 1. The elastic telescopic plates 151 are slidably arranged in the inner cavity of the chute 152. An upper arc block 153 is fixedly installed on the top of one side of the elastic telescopic plate 151. A plurality of lower arc blocks 154 are fixedly installed at the bottom edge of the filter sleeve 52. The arc surfaces of the upper arc blocks 153 and the lower arc blocks 154 are tangent.

[0063] The servo motor 12 drives the connecting rod 10 and the sealing plate 51 at the bottom of the connecting rod 10 to rotate, thereby driving multiple lower arc blocks 154 to rotate with the connecting rod 10 as the axis. By setting the lower arc block 154 tangent to the arc surface of the upper arc block 153, the lower arc block 154 rotates and its lowest end contacts the top of the upper arc block 153. During this process, the lower arc block 154 squeezes the upper arc block 153 and causes the upper arc block 153 and the elastic telescopic plate 151 on one side to move downward. When the lower arc block 154 continues to rotate and its lowest end is separated from the top of the upper arc block 153, the upper arc block 153 is not squeezed, thereby causing the upper arc block 153 and the elastic telescopic rod 73 on one side to move upward.

[0064] Further, see Figure 10 Regarding the vibration assembly 15, a horizontal plate 155 is fixedly mounted on the bottom of one side of the elastic expansion plate 151. The top surface of the horizontal plate 155 is in contact with the bottom surface of the collection bin 613. A guide rod is fixedly mounted in the inner cavity of the chute 152. The guide rod passes through the elastic expansion plate 151. A fourth spring 156 is provided at the bottom of the elastic expansion plate 151. The fourth spring 156 is sleeved around the outer circumference of the guide rod.

[0065] When the elastic telescopic rod 73 is squeezed by the lower arc block 154 and moves downward, the elastic telescopic plate 151 squeezes the fourth spring 156, so that the bottom of the collection bin 613 is not under force, so that the first spring 616 recovers its elasticity and pushes the collection bin 613 downward. When the elastic telescopic rod 73 is no longer squeezed by the lower arc block 154, the fourth spring 156 recovers its elasticity and drives the elastic telescopic rod and the horizontal plate 155 to move upward, thereby driving the collection bin 613 to move upward and compressing the first spring 616. The above actions are repeated, thereby shaking the inner cavity of the collection bin 613, thereby accelerating the absorption of trace mercury contained in the mercury waste liquid after secondary filtration by the adsorbent in the inner cavity of the collection bin 613.

[0066] Working principle: When in use, the driving device 7 drives the sealing plate 51 to move downward, so that the bottom of the sealing plate 51 contacts the top of the inner cavity of the sleeve 611, and the unlocking component 9 does not contact the locking component 8, thereby achieving the effect of sealing the top of the filter element 61. At the same time, as the sealing plate 51 descends, the bottom edge of the sealing plate 51 contacts the upper arc block 153. At this time, when the sealing plate 51 moves downward, the elastic telescopic plate 151 moves downward, and the fourth spring 156 is in a compressed state, and at the same time, the elastic telescopic plate 151 is squeezed and compressed.

[0067] In the inner cavity of the collection tank 1, after the sealing plate 51 seals the filter element 61, the mercury waste liquid and the corresponding chemical raw materials are introduced into the inner cavity of the collection tank 1 through the water inlet. Then, the servo motor 12 drives the connecting rod 10 to rotate, thereby driving the stirring blade 11 and the sealing plate 51 at the bottom of the connecting rod 10 to rotate, thereby stirring the mercury waste liquid and the chemical raw materials, thereby accelerating the flocculation of impurities in the mercury waste liquid. At the same time, the centrifugal force generated by the rotation of the sealing plate 51 causes the impurities on the sealing plate 51 to move toward the filter sleeve 52, thereby forming a primary filtration, and the impurities filtered out of the primary filtration are collected in the inner cavity of the filter sleeve 52;

[0068] After standing for a period of time, the sealing plate 51 is driven upward by the driving device 7. At this time, the mercury waste liquid between the sealing cover plate 22 and the sealing plate 51 flows downward from the filter holes at the bottom of the filter sleeve 52, so that the mercury waste liquid after the primary filtration flows into the filter membrane 612 in the filter element 61. The mercury waste liquid after the primary filtration is filtered for a second time by the filter membrane 612, and the mercury generated during the reaction of the primary filtration is retained on the filter membrane 612, thereby performing a second filtration on the mercury waste liquid.

[0069] The mercury waste liquid after secondary filtration passes through the filter membrane 612 and flows downward, thereby entering the inner cavity of the collection chamber 613. The inner cavity of the collection chamber 613 is filled with activated carbon, which absorbs the trace amount of mercury remaining in the inner cavity of the collection chamber 613, thereby achieving a three-stage filtration of the mercury waste liquid and further achieving the effect of purifying the mercury waste liquid;

[0070] When the mercury waste liquid is adsorbed by the activated carbon, the servo motor 12 drives the sealing plate 51 to rotate, thereby driving the multiple lower arc blocks 154 to rotate with the connecting rod 10 as the axis. The lower arc block 154 is tangent to the arc surface of the upper arc block 153, so that the lower arc block 154 rotates and its lowest end contacts the top of the upper arc block 153. During this process, the lower arc block 154 squeezes the upper arc block 153 and makes the upper arc block 153 and the elastic expansion plate 151 on one side move downward. At this time, the elastic expansion plate 151 squeezes the fourth spring 156, so that the bottom of the collection bin 613 The first spring 616 is no longer under stress, thereby restoring its elasticity and pushing the collection chamber 613 downward. When the lower arc block 154 continues to rotate and its lowest end separates from the top of the upper arc block 153, the upper arc block 153 is not squeezed. The fourth spring 156 regains its elasticity and drives the elastic telescopic stem and the horizontal plate 155 to move upward, thereby driving the collection chamber 613 upward and compressing the first spring 616. The above actions are repeated, thereby shaking the inner cavity of the collection chamber 613, thereby accelerating the absorption of trace mercury contained in the mercury waste liquid after secondary filtration by the adsorbent in the inner cavity of the collection chamber 613.

[0071] When the mercury waste liquid in the inner cavity of the collection tank 1 is collected, the sealing plate 51 is driven downward by the driving device 7, and the lower end of the sealing plate 51 enters the upper part of the inner cavity of the sleeve 611. During this process, the second clamping block 91 is squeezed by the sleeve 611, so that the second clamping block 91 is accommodated in the inner cavity of the second built-in groove 93, and the third spring 92 is in an extruded state. When the sealing plate 51 enters the inner cavity of the sleeve 611 to a certain extent and the second built-in groove 93 coincides with the clamping hole 14, the second clamping block 91 is not squeezed, so that the third spring 92 recovers its elasticity and drives the second clamping block 91 to be squeezed. The card block moves into the card hole 14, thereby pushing the first card block 81 in the card hole 14 toward the inner cavity of the first built-in groove 83, so that the first card block 81 is separated from the card hole 14, so that the filter element 61 and the fixing sleeve 62 can be movable, and the sealing plate 51 and the filter element 61 are fixed. Then, the sealed filter element 61 is moved upward by the driving device 7 and moved out of the collection tank 1, and the sealing plate 51 and the filter element 61 at the bottom are removed, so as to process the mercury in the inner cavity of the filter element 61 to prevent the mercury from volatilizing into harmful gases after being extracted.

[0072] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
