Description

Technical Field

[0001] This utility model belongs to the technical field of solid-liquid separation equipment, specifically relating to an ammonium thiocyanate solid-liquid separation device. Background Technology

[0002] Ammonium thiocyanate is an inorganic, colorless crystalline substance that is irritating, deliquescent, readily soluble in water and ethanol, soluble in methanol and acetone, and almost insoluble in chloroform and ethyl acetate. Its aqueous solution turns blood red in the presence of ferrous salt solutions, but does not react with ferrous salts. Currently, in the process of treating ammonium thiocyanate, waste liquid separation is required, which necessitates the use of solid-liquid separation equipment.

[0003] According to the patent announcement number CN214167369U regarding an ammonium thiocyanate waste liquid separation device, this patent is a known prior art.

[0018] Please see Figure 1 and Figure 2 This utility model provides an ammonium thiocyanate solid-liquid separation device, including a shell 1. Support legs 3 are fixedly installed at the bottom of the shell 1 near the four corners. Liquid guide holes 15 are opened between the first separation chamber 7 and the second separation chamber 10 and the liquid storage chamber 11. A discharge valve 4 is fixedly installed on the side of the second separation chamber 10 and a discharge valve 2 is fixedly installed on the side of the liquid storage chamber 11. Heating plates 18 are provided on the inner walls of the first separation chamber 7 and the second separation chamber 10. In this embodiment, the liquid and impurities after separation of ammonium thiocyanate waste liquid are conveniently discharged separately by means of the drain valve 2 and the discharge valve 4. When the heating plate 18 is turned on, the waste liquid can be heated to ensure the internal temperature of the shell 1 and improve the separation efficiency.

[0019] Please see Figure 2 The housing 1 has a first separation chamber 7, a second separation chamber 10 and a liquid storage chamber 11 inside. The liquid storage chamber 11 is used to collect the separated ammonium thiocyanate liquid. The top of the housing 1 is mounted with a top plate 5 by studs. A drive assembly 6 is fixedly mounted on the top of the top plate 5. The drive assembly 6 includes a first motor 61 and a first bearing 64. The first motor 61 and the first bearing 64 are both fixedly connected to the top of the top plate 5. A drive gear 62 is fixedly connected to the output shaft of the first motor 61. A first hollow shaft 65 is rotatably connected inside the first bearing 64. A driven gear 63 is fixedly connected to the surface of the first hollow shaft 65. The drive gear 62 and the driven gear 63 are meshed together. In this embodiment, when the first motor 61 is turned on, it drives the drive gear 62 to rotate. Through the meshing connection between the drive gear 62 and the driven gear 63, it drives the first hollow shaft 65 to rotate, which can achieve the purpose of driving the separation component 16 to rotate. At the same time, by setting the first hollow shaft 65, it is convenient to introduce ammonium thiocyanate waste liquid into the separation frame 167 for separation treatment.

[0020] Please see Figure 1 and Figure 4A separation component 16 is fixedly connected to the bottom of the drive assembly 6. The separation component 16 is located inside the first separation chamber 7. The separation component 16 includes a separation frame 167. A cover plate 161 is fixedly installed on the top of the separation frame 167 by studs. The cover plate 161 is fixedly connected to the surface of the first hollow rotating shaft 65. A hollow lead screw 162 is fixedly connected to the bottom end of the first hollow rotating shaft 65. A threaded sleeve 168 is threadedly connected to the surface of the hollow lead screw 162. Four connecting plates 164 are fixedly connected to the surface of the threaded sleeve 168. The bottom of each of the four connecting plates 164 is... A spiral stirring rod 165 is fixedly connected. Four sliding rods 163 are fixedly connected to the bottom of the cover plate 161. Four connecting plates 164 are slidably connected to the surface of the sliding rods 163. Multiple filter holes 166 are opened on the surface of the separation frame 167. A second hollow rotating shaft 8 is snapped into the bottom of the separation frame 167. A second bearing 9 is fixedly connected between the first separation chamber 7 and the second separation chamber 10. The second hollow rotating shaft 8 is rotatably connected to the second bearing 9. The bottom end of the second hollow rotating shaft 8 is located above the material carrier plate 14. A solenoid valve 19 is installed inside the second hollow rotating shaft 8. In this embodiment, when the first hollow rotating shaft 65 rotates, it drives the separation frame 167 to rotate through the cover plate 161. With the help of the filter holes 166 on the surface of the separation frame 167, the liquid in the ammonium thiocyanate waste liquid is rotated and thrown out, and preliminary solid-liquid separation is performed. At the same time, the rotation of the first hollow rotating shaft 65 drives the hollow lead screw 162 to rotate, which will drive the threaded sleeve 168 and the connecting plate 164 to move up and down. At the same time, with the help of the sliding action of the connecting plate 164 on the surface of the slide rod 163, the connecting plate 164 is prevented from rotating. The connecting plate 164 drives the spiral feeding rod to move up and down to circulate and stir the ammonium thiocyanate waste liquid, thereby improving the filtration effect and efficiency. The solenoid valve 19 is opened, and with the help of the second hollow rotating shaft 8, it is convenient to transport the impurities after preliminary separation to the second separation chamber 10 for further processing.

[0021] Please see Figure 1 and Figure 3A compression assembly 12 is installed inside the second separation chamber 10. The compression assembly 12 includes a groove 127, which is formed on the rear side of the inner wall of the second separation chamber 10. A third bearing 125 is fixedly connected to the side of the inner wall of the groove 127. A third shaft 124 is rotatably connected inside the third bearing 125. A first lead screw 128 is fixedly connected to one end of the third shaft 124. A compression plate 121 is threaded onto the surface of the first lead screw 128. A support plate 122 is fixedly connected to the side of the second separation chamber 10. A second motor 123 is fixedly installed on the support plate 122. The output shaft of the second motor 123 is fixedly connected to the shaft end of the third rotating shaft 124. Slide grooves 126 are provided at the top and bottom of the inner wall of the groove 127. The extrusion plate 121 is slidably connected in the slide groove 126. A material carrier plate 14 is fixedly installed inside the second separation chamber 10. A filter groove 13 is provided on the material carrier plate 14. The bottom of the extrusion plate 121 overlaps with the surface of the material carrier plate 14. The top of the extrusion plate 121 does not contact the bottom of the second hollow rotating shaft 8. In this embodiment, when the third motor is turned on, the first lead screw 128 rotates, and the first lead screw 128 drives the extrusion plate 121 to rotate and move. At this time, the extrusion plate 121 slides in the slide groove 126 to prevent the rotational movement tendency, so that the extrusion plate 121 moves horizontally. The movement of the extrusion plate 121 extrudes the impurities separated on the carrier plate 14, thereby achieving the purpose of secondary solid-liquid separation of impurities and liquid in the ammonium thiocyanate waste liquid.

[0022] Please see Figure 2 and Figure 5 A circulation assembly 17 is fixedly installed on the rear side of the liquid storage chamber 11. The circulation assembly 17 includes a pump 171, which is fixedly installed on the rear side of the liquid storage chamber 11. One end of the pump 171 is fixedly connected to a guide pipe 172, and the other end of the guide pipe 172 is fixedly connected to a rotary joint 20. The bottom end of the rotary joint 20 is movably fitted onto the top end of the first hollow rotating shaft 65. The top of the rotary joint 20 is fixedly connected to a conveying pipe 21. A limiting cylinder 173 is fixedly connected to the rear side of the liquid storage chamber 11. The guide pipe 172 passes through the limiting cylinder 173. A limiting plate 22 is fixedly connected to the top of the top plate 5. The rigid part of the guide pipe 172 is snapped into the limiting plate 22.

[0023] In this embodiment, when the pump 171 is turned on, the impurities accumulated at the bottom of the storage chamber 11 are extracted and transported to the first hollow rotating shaft 65 through the hollow setting inside the rotary joint 20 via the guide pipe 172. The rotary joint 20, in conjunction with the rotation of the first hollow rotating shaft 65, prevents the guide pipe 172 from becoming entangled, thereby achieving the effect of recirculation filtration and separation. The limiting plate 22 is used to clamp and support the rigid part of the guide pipe 172, and to limit and fix the rotary joint 20.

[0024] The working principle and usage process of this utility model are as follows: First, the conduit containing the ammonium thiocyanate waste liquid can be connected to the conveying pipe 21 at the top of the rotary joint 20. Then, the ammonium thiocyanate waste liquid is conveyed into the separation frame 167. At the same time, the first motor 61 is turned on, which drives the active gear 62 and the driven gear 63 to mesh and rotate, causing the separation frame 167 to rotate, which in turn drives the waste liquid to rotate. The waste liquid is thrown out by means of the surface filter holes 166. At the same time, the first hollow rotating shaft 65 rotates, which drives the hollow screw 162 to rotate, causing the threaded sleeve 168 to drive the connecting plate 164 to slide up and down on the surface of the slide rod 163. This causes the spiral stirring rod 165 to move up and down, pumping and stirring the waste liquid up and down, thus completing the initial solid-liquid separation of the ammonium thiocyanate waste liquid. Simultaneously, the initially separated liquid enters the storage chamber 11 for storage. Then, the solenoid valve 19 is opened, and the solid impurities in the ammonium thiocyanate waste liquid in the separation frame 167 are transported to the loading plate 14 through the second hollow rotating shaft 8. Then, the second motor 123 is turned on, and when the third rotating shaft 124 drives the first lead screw 128 to rotate, the extrusion plate 121 moves to extrude the solid impurities again. The liquid enters the bottom of the second separation chamber 10 through the filter tank 13 and enters the storage chamber 11 through the liquid guide hole 15 for storage, thus completing the secondary extrusion separation of solid impurities in the ammonium thiocyanate waste liquid. During the initial solid-liquid separation and secondary extrusion separation process, the heating plate 18 is turned on to maintain the internal temperature of the shell 1 and improve the separation effect. Finally, the liquid is stored in the storage chamber 11. After a period of use, the impurities accumulated at the bottom of the storage chamber 11 can be pumped out by turning on the pump 171. The impurities are then transported through the guide pipe 172 and the hollow structure inside the rotary joint 20 to the first hollow rotating shaft 65. At the same time, with the cooperation of the rotary joint 20, the rotation of the first hollow rotating shaft 65 is not affected, and the impurities of the ammonium thiocyanate waste liquid are recycled and separated again. After a period of use, the rotary joint 20 can be separated from the first hollow rotating shaft 65. With the help of the flexible part of the guide tube 172, the guide tube 172 and the rotary joint 20 are pulled to one side of the housing 1. Then, the top plate 5 and the cover plate 161 are removed, and the separation component 16 and the internal components of the housing 1 are cleaned.
