Description

Technical Field

[0001] The utility model relates to the technical field of stannous octoate purification, in particular to a filtering and purification device used for stannous octoate production. Background Art

[0002] Many organometallic compounds, such as alkyl compounds and carboxylates of lead, tin, titanium, antimony, mercury, zinc, bismuth, zirconium, and aluminum, catalyze isocyanate-hydroxyl reactions. However, tin organic compounds, particularly stannous octoate, are crucial in polyurethane foam production, as they are widely used in polyurethane foams, adhesives, elastomers, and more.

[0003] In the polyurethane field, stannous octoate is primarily used as a polyurethane catalyst, primarily in the production of soft, blocky polyether-based polyurethane foams. It can also be used as a catalyst for polyurethane coatings, elastomers, and room-temperature-curing silicone rubber. Because it is a divalent tin compound, it can be oxidized to a tetravalent tin compound after foaming, remaining in the foam and acting as an antioxidant. Its presence in the foam after foaming does not adversely affect foam properties.

[0004] Since the chemical valence state of the key element tin in the product stannous octoate is +2, which is an unstable intermediate valence state of tin, in the actual production process, the presence of oxidants (air, chlorine, sulfuric acid, etc.) may easily cause the substance stannous octoate to undergo an oxidation reaction to produce tin octoate, in which the +2 tin is oxidized to a metallic valence state of +4. Although tetravalent tin compounds can be used as antioxidants, these substances will greatly reduce their foaming activity and significantly reduce the content of stannous octoate. Utility Model Content

[0005] In order to solve the problems mentioned in the above background technology, the utility model provides a filtering and purification device for the production of stannous octoate.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Preferably, the discharge port and the filter are fixed via a first support frame and a support base, a filter element is installed inside the filter, and a filter element replacement port is provided.

[0009] Preferably, a bevel gear ring is fixed to the outside of the sedimentation separation tank, a first rotating motor is fixed to the top of the support base through a second supporting frame, a first bevel gear is fixed to the output end of the first rotating motor, and the first bevel gear is meshed with the bevel gear ring.

[0011] Preferably, a connecting cross bar is fixed to the top of the support base through a third support frame, and a plurality of spur gear rings are fixed on the connecting cross bar, and the plurality of spur gear rings are meshed with the plurality of spur gears in a one-to-one correspondence.

[0012] Preferably, a first rotating shaft is installed on the circular stirring disk, and both ends of the first rotating shaft extend to both sides of the circular stirring disk respectively, and a scraper is fixed to one end of the first rotating shaft close to the feed port, and a second bevel gear is fixed to the other end of the first rotating shaft, the second bevel gear is located in the protective cover, and a second rotating shaft is rotatably installed on the protective cover, and a third bevel gear is fixed to one end of the second rotating shaft, and the third bevel gear is meshed with the second bevel gear.

[0013] Preferably, a first arc plate is fixed to the other end of the second rotating shaft, a second rotating motor is fixed to the outer wall of the sedimentation separation tank, the output end of the second rotating motor is connected to a drive shaft, the drive shaft extends to the interior of the sedimentation separation tank and is respectively fixed with a second arc plate and a third arc plate, and the first arc plate extends between the second arc plate and the third arc plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Add stannous octoate containing impurities into the precipitation separation tank through the feed port, and add tetravalent tin flocculant. After flocculation is fully completed, discharge the material from the discharge port, filter the solid through the filter, and discharge the liquid from the filtrate discharge port, which can effectively remove stannous octoate impurities;

[0016] 2. The solids flocculated by the flocculant are filtered out through the filter. The filter element can be regularly removed and cleaned and replaced to ensure that the filtering effect will not be reduced. Since the discharge port and the filter are rotatably connected to the sedimentation separation tank, the discharge port and the filter will not rotate with the sedimentation separation tank during its rotation, thereby ensuring that the rotation of the sedimentation separation tank will not affect the connection between the filtrate discharge port and the flushing liquid discharge port and the pipeline;

The first rotating motor can drive the first bevel gear to rotate, thereby driving the entire sedimentation separation tank to rotate through the engagement of the first bevel gear and the bevel gear ring, thereby driving the mixed liquid to shake and mix in the sedimentation separation tank through the action of gravity, thereby accelerating the mixing speed between the flocculant and the solution and improving the flocculation efficiency;

[0018] 4. During the rotation of the sedimentation separation tank, since the spur gear ring is fixed relative to the supporting base, the spur gear will continuously move along the spur gear ring during the rotation of the sedimentation separation tank, thereby driving the circular stirring disk to continuously flip inside the sedimentation separation tank, thereby achieving a stirring effect, further improving the mixing rate of the flocculant and the solution, accelerating flocculation, and no additional power device is required, which is more energy-saving and environmentally friendly;

[0019] 5. After flocculation is completed, when discharging the liquid, the circular stirring plate can be adjusted to a state perpendicular to the direction of liquid flow ( Figure 4 In the middle state), during the process of releasing the liquid, most of the solid impurities will be filtered through the circular stirring disk and remain on the side of the circular stirring disk close to the feed inlet. The circular stirring disk can not only play the stirring function but also pre-filter the material, thereby reducing the filtration pressure of the filter and preventing the accumulation of solid impurities in the filter position and reducing the filtration efficiency.

[0020] 6. Turning on the second rotating motor can drive the scraper to actively clean the surface of the circular stirring plate without affecting the rotation of the circular stirring plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are 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.

[0036] Example 1

[0037] Reference Figure 1-12 A filtering and purification device for the production of stannous octoate, comprising a sedimentation separation tank 1 and a water washing tank 6, wherein the sedimentation separation tank 1 is tiltably mounted on the top of a support base 2, wherein one end of the sedimentation separation tank 1 is provided with a feed port 105, and the other end of the sedimentation separation tank 1 is rotatably connected to a discharge port 101, wherein the horizontal height of one side of the discharge port 101 is less than the horizontal height of the one side of the feed port 105, and a filter 102 is fixed on the discharge port 101, wherein the filter 102 is connected to a filtrate discharge port 104, and the discharge port 101 is also connected to a flushing liquid discharge port 103;

[0038] Stannous octoate containing impurities is added to the sedimentation separation tank 1 through the feed port 105, and a tetravalent tin flocculant is added. After flocculation is fully completed, the material is discharged from the discharge port 101, the solid is filtered out through the filter 102, and the liquid is discharged from the filtrate discharge port 104 and transported to the water washing tank 6. Since the sedimentation separation tank 1 is installed at an angle, the material can be discharged by gravity, and the tetravalent tin compound impurities can be removed after passing through the sedimentation separation tank 1. After multiple water washings, the stannous chloride impurities are removed, thereby completing the purification, which can effectively improve the purity of the product and improve the quality of the product.

[0039] The discharge port 101 and the filter 102 are fixed to the support base 2 via the first support frame 202. A filter element is installed inside the filter 102, and a filter element replacement port is provided.

[0040] The solids flocculated by the flocculant are filtered out through the filter 102, and the filter element can be regularly removed and cleaned and replaced to ensure that the filtering effect will not be reduced. Since the discharge port 101 and the filter 102 are rotatably connected to the sedimentation separation tank 1 as a whole, the discharge port 101 and the filter 102 will not rotate with the sedimentation separation tank 1 during the rotation, thereby ensuring that the rotation of the sedimentation separation tank 1 will not affect the connection between the filtrate discharge port 104 and the flushing liquid discharge port 103 and the pipeline.

[0041] Example 2

[0042] Reference Figure 1-12The difference between this embodiment and embodiment 1 is that a bevel gear ring 106 is fixed to the outside of the sedimentation separation tank 1, a first rotating motor 3 is fixed to the top of the support base 2 through a second support frame 201, a first bevel gear 301 is fixed to the output end of the first rotating motor 3, and the first bevel gear 301 is meshed with the bevel gear ring 106;

[0043] The first rotating motor 3 can drive the first bevel gear 301 to rotate, thereby driving the sedimentation separation tank 1 to rotate as a whole through the engagement of the first bevel gear 301 with the bevel gear ring 106, thereby driving the mixed liquid to shake and mix in the sedimentation separation tank 1 through the action of gravity, thereby accelerating the mixing speed between the flocculant and the solution and improving the flocculation efficiency.

[0044] Example 3

[0045] Reference Figure 1-12 The difference between this embodiment and embodiment 2 is that a plurality of circular stirring discs 4 are evenly distributed inside the sedimentation separation tank 1, and a plurality of leakage holes 401 are opened on the circular stirring discs 4. The circular stirring discs 4 are rotatably mounted inside the sedimentation separation tank 1, and a rotating shaft on one side of the circular stirring disc 4 extends to the outside of the sedimentation separation tank 1 and is fixed with a spur gear 402. A connecting crossbar 204 is fixed to the top of the support base 2 through a third support frame 203, and a plurality of spur gear rings 205 are fixed on the connecting crossbar 204. The plurality of spur gear rings 205 are meshed with the plurality of spur gears 402 in a one-to-one correspondence.

[0046] During the rotation of the sedimentation separation tank 1, since the spur gear ring 205 is fixed relative to the support base 2, the spur gear 402 will continuously move along the spur gear ring 205 during the rotation of the sedimentation separation tank 1 inside the spur gear ring 205, thereby driving the circular stirring disk 4 to continuously flip inside the sedimentation separation tank 1, thereby achieving a stirring effect, further improving the mixing rate of the flocculant and the solution, accelerating flocculation, and no additional power device is required, which is more energy-saving and environmentally friendly.

[0047] After flocculation is completed, when discharging the liquid, the circular stirring disc 4 can be adjusted to a state perpendicular to the direction of liquid flow ( Figure 4 In the middle state), during the process of releasing the liquid, most of the solid impurities will be filtered through the circular stirring disk 4 and remain on the side of the circular stirring disk 4 close to the feed inlet 105. The circular stirring disk 4 can not only play the stirring function but also pre-filter the material, thereby reducing the filtration pressure of the filter 102 and preventing the occurrence of the phenomenon that the filtration efficiency is reduced due to the accumulation of solid impurities at the filter 102 position.

[0048] When it is necessary to flush the interior of the sedimentation separation tank 1 and discharge solid impurities, the circular stirring disk 4 is adjusted to a state parallel to the liquid flow direction, and the interior of the sedimentation separation tank 1 and the circular stirring disk 4 are flushed with cleaning liquid to carry away the solid impurities and discharge them through the flushing liquid discharge port 103.

[0049] Example 4

[0050] Reference Figure 1-12 The difference between this embodiment and embodiment 3 is that a first rotating shaft 403 is installed on the circular stirring disk 4, and the two ends of the first rotating shaft 403 extend to the two sides of the circular stirring disk 4 respectively, and a scraper 405 is fixed to one end of the first rotating shaft 403 close to the feed port 105, and a second bevel gear 404 is fixed to the other end of the first rotating shaft 403. The second bevel gear 404 is located in the protective cover, and a second rotating shaft 406 is rotatably installed on the protective cover, and a third bevel gear is fixed to one end of the second rotating shaft 406. 407, the third bevel gear 407 is meshed with the second bevel gear 404, the other end of the second rotating shaft 406 is fixed with a first arc plate 408, the outer wall of the sedimentation separation tank 1 is fixed with a second rotating motor 5, the output end of the second rotating motor 5 is connected to a drive shaft 501, the drive shaft 501 extends into the interior of the sedimentation separation tank 1 and is respectively fixed with a second arc plate 502 and a third arc plate 503, the first arc plate 408 extends between the second arc plate 502 and the third arc plate 503;

[0051] The second rotating motor 5 can drive the second arc plate 502 and the third arc plate 503 to rotate. When the second arc plate 502 and the third arc plate 503 rotate to a certain state, the arc center points of the second arc plate 502 and the third arc plate 503 coincide with the mounting shaft of the circular stirring disk 4. At this time, the arc center point of the first arc plate 408 coincides with the mounting shaft of the circular stirring disk 4. In this state, when the first arc plate 408 rotates as a whole with the circular stirring disk 4, the first arc plate 408 will just pass between the second arc plate 502 and the third arc plate 503, thereby ensuring that the three will not interfere with each other, and there is a certain damping between the first rotating shaft 403 and the circular stirring disk 4, ensuring that during the rotation of the circular stirring disk 4, the first rotating shaft 403 will not rotate due to the action of fluid pressure and inertia, thereby ensuring that the first arc plate 408 will not deflect arbitrarily;

[0052] When it is necessary to actively clean the solid impurities on the surface of the circular stirring disk 4, first stop the circular stirring disk 4 Figure 4The state of the first circular arc plate 408 is ensured to be exactly sandwiched between the second circular arc plate 502 and the third circular arc plate 503. At this time, turning on the second rotating motor 5 can drive the second circular arc plate 502 and the third circular arc plate 503 to rotate, and the second circular arc plate 502 and the third circular arc plate 503 will clamp the first circular arc plate 408 to rotate, thereby driving the second rotating shaft 406 to rotate, and the third bevel gear 407 is engaged with the second bevel gear 404 to drive the scraper 405 to actively clean the surface of the circular stirring disk 4. After the cleaning is completed, it is necessary to ensure that the second circular arc plate 502, the third circular arc plate 503 and the first circular arc plate 408 stop in a state where the center points of the three arcs coincide with the rotating shaft of the circular stirring disk 4, so as to ensure that the rotation of the circular stirring disk 4 is not affected, thereby achieving the effect of actively cleaning the circular stirring disk 4 without affecting the rotation of the circular stirring disk 4 itself.

[0054] Reference Figure 1-12 The difference between this embodiment and embodiment 1 is that a material addition port 602 and a water inlet 601 are provided at the top of the water washing tank 6, a discharge port 603 is provided at the bottom of the water washing tank 6, and the water washing tank 6 further includes a circulation pump 8, a liquid inlet pipe 801 of the circulation pump 8 is connected to the discharge port 603, a liquid outlet pipe 802 of the circulation pump 8 is connected to the water inlet 601, and a water supply branch pipe 802 is further provided on the liquid outlet pipe 802;

[0055] The material after one purification is added into the water washing tank 6 through the material adding port 602, and pure water is added into the water washing tank 6 through the water adding branch pipe 802. The mixed liquid is pumped out from the discharge port 603 through the circulating pump 8 and injected back into the water washing tank 6 from the water inlet 601, so that the mixed material can be circulated and washed, thereby improving the washing efficiency.

[0056] The water washing tank 6 is provided with a heat insulation interlayer 604, a heat medium inlet pipe 605 is provided on one side of the water washing tank 6, and a heat medium outlet pipe 606 is provided on the other side of the water washing tank 6. The heat medium inlet pipe 605 and the heat medium outlet pipe 606 are connected to the heat insulation interlayer 604;

[0057] By introducing a heat medium into the heat-insulating interlayer 604, the material is kept warm, thereby increasing the solubility of the impurity stannous chloride in water, thereby enabling more efficient extraction and separation of the stannous chloride.

[0058] A guide baffle 606 is fixed inside the thermal insulation interlayer 604, and the guide baffle 606 extends in a spiral shape;

[0059] The flow guide baffle 606 can extend the distance that the heat medium flows inside the thermal insulation interlayer 604 and increase the residence time of the heat medium in the thermal insulation interlayer 604, thereby improving the thermal insulation effect.

[0060] Among them, an agitator 7 is rotatably mounted on the inner wall of the top of the water washing tank 6, and a plurality of agitation branches 702 are fixed on the agitator 7. The agitator 7 is driven to rotate by a third rotary motor 701 installed on the top of the water washing tank 6;

[0061] The stirrer 7 can be driven by the stirrer 7 to stir the material, thereby accelerating the dissolution of stannous chloride into water and improving the extraction and separation efficiency of stannous chloride.

[0062] Among them, an annular mounting frame 9 is installed near the top position inside the washing tank 6, and an annular mounting frame 9 is fixedly installed on the annular mounting frame 9. An annular notch 902 is opened on the inner side of the annular tube 901, and a retaining ring 903 corresponding to the annular notch 902 is provided inside the annular tube 901. A plurality of horizontal drainage pipes 904 are fixed on the inner side of the retaining ring 903. The end of the horizontal drainage pipe 904 close to the agitator 7 passes through the annular notch 902 and is fixed to the agitator 7. The annular tube 901 is connected to the water inlet 601. A vertical drainage pipe 905 is installed at the bottom end of the horizontal drainage pipe 904, and a plurality of drainage branches 906 are fixed on the vertical drainage pipe 905. A plurality of drainage holes 907 are opened on the drainage branch 906.

[0063] The liquid flowing into the washing tank 6 through the water inlet 601 first enters the annular tube 901, and then dispersed into each horizontal drainage tube 904, and then dispersed into the drainage branch 906 through the vertical drainage tube 905, and then dispersedly discharged from the drainage hole 907. This method can greatly improve the dispersion of the liquid, thereby accelerating the water washing process, and since the horizontal drainage tube 904 and the agitator 7 are fixed, the horizontal drainage tube 904, the baffle 903, the vertical drainage tube 905 and the drainage branch 906 will all rotate with the agitator 7, thereby playing a role in auxiliary stirring and improving the stirring effect, and the position of the drainage hole 907 will also change constantly, which can further improve the dispersion of the liquid.
