Description

Technical Field

[0001] This utility model relates to the field of chemical crystallization technology, and in particular to a filter device for producing VB12. Background Technology

[0002] In the production of VB12, the crystallization solution of VB12 needs to be precipitated with crystallizing acetone to obtain VB12 product. During this process, the crystallization tank needs to be opened manually to observe and judge whether the crystals have been completely precipitated. This method has certain safety hazards and is unsafe, which will cause the vacuum filter to be operated.

[0003] In existing vacuum filters, the crystals are typically transferred directly into the filter and fall onto the filter components inside. This can easily cause the crystals to pile up on the filter components, thus affecting the filtration effect. Therefore, in order to solve the above defects, the inventors propose a vacuum filter device for producing VB12. Utility Model Content

[0004] The main objective of this invention is to provide a filter device for producing VB12, which can effectively solve the problem in the prior art that crystals are easily stacked on the filter components, thereby affecting the filtration effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A filter device for producing VB12 includes a filter, a crystallizer, a nitrogen system, a liquid extraction system, an air system, and an acetone system. A support ring is fixedly installed inside the filter, and a sintered plate is fixedly connected to the top surface of the support ring. A support ring is fixedly installed inside the filter, and a sieve plate is provided on the top surface of the support ring. Two drive components are provided at the bottom of the support ring.

[0007] Preferably, the drive assembly includes a protective box fixedly installed on the bottom surface of the support ring, a movable rod slidably connected inside the protective box, the top end of the movable rod passing through the support ring and fixedly connected to the sieve plate, a first spring fixedly installed at the bottom of the movable rod, and the first spring fixedly connected to the bottom surface of the support ring, and a movable wheel rotatably connected to the bottom end of the movable rod.

[0008] Preferably, the filter is internally rotatably connected to a first rotating shaft, which passes through the interior of two protective boxes. Cams are fixedly installed on both sides of the outer surface of the first rotating shaft inside the two protective boxes, and the cams are rotatably connected to the movable wheel. A first motor is fixedly installed on the left side of the outer surface of the filter, and the output shaft of the first motor is fixedly connected to the first rotating shaft.

[0009] Preferably, a fixed box is fixedly installed inside the filter, a second rotating shaft is rotatably connected inside the filter, and a protective box is sleeved on the outer end of the second rotating shaft. A first bevel gear is fixedly installed on the side of the outer surface of the second rotating shaft located inside the fixed box. A second motor is fixedly installed on the left side of the outer surface of the filter, and the output shaft of the second motor is fixedly connected to the second rotating shaft.

[0010] Preferably, a rotating rod is rotatably connected to the inner bottom surface of the fixed box. One end of the rotating rod is located inside the fixed box and a second bevel gear is fixedly installed thereon, while the other end of the rotating rod is located outside the fixed box and a connecting plate is fixedly installed thereon. The second bevel gear meshes with the first bevel gear.

[0011] Preferably, a telescopic sleeve is fixedly installed on the bottom surface of the connecting plate, a brush plate is slidably connected inside the telescopic sleeve, and a second spring is fixedly installed on one side of the inner wall of the telescopic sleeve, and the second spring is fixedly connected to the brush plate.

[0012] Preferably, a crystallization tube is fixedly installed on the left side of the outer surface of the filter, an air tube is fixedly installed on the left side of the outer surface of the filter, a nitrogen tube is fixedly installed on the right side of the outer surface of the filter, a liquid extraction tube is fixedly installed on the bottom surface of the filter, and a connecting cover is provided on the top surface of the filter.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model discloses a filter device for producing VB12. By setting up the filter, in actual operation:

[0015] 1. The first motor drives the first rotating shaft to rotate, which in turn drives the two cams to rotate. The two rotating cams, together with the two first springs, cause the two movable rods to move up and down reciprocally. When the crystals fall through the crystallization tube onto the top surface of the sieve plate, the up-and-down moving sieve plate will cause the crystals to shake. During the shaking process, the crystals will fall onto the sintering plate for filtration, thus effectively avoiding the impact of crystal stacking on the sintering plate on the filtration effect.

[0016] 2. After crystallization in the crystallizer, the crystals are fed into a filter. The filter has a sintered plate with a certain pore size to prevent crystal leakage. Residual crystallization solution leaks out through the sintered plate and into the extraction system, returning to the crystallizer for reuse. Acetone is introduced to wash the crystals, while the nitrogen system is backflushed. After a certain period of time, the crystal washing and nitrogen system operations are stopped, and residual gas is extracted to dry the crystals as much as possible. This allows for more accurate determination of complete crystal precipitation in the crystallization solution, preventing crystal waste, increasing safety, and reducing human error.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] This utility model discloses a filter device for producing VB12, such as... Figure 1-7 As shown, it includes a filter 1, a crystallizer 2, a nitrogen system 3, a liquid extraction system 4, an air system 5, and an acetone system 6. The crystallizer 2 achieves the production of high-purity crystals by precisely controlling the supersaturation, nucleation, and growth conditions.

[0027] Crystallization tank 2, nitrogen system 3, liquid pumping system 4, air system 5, and acetone system 6 are all existing technologies and will not be described in detail here.

[0028] After crystallization in crystallizer 2, the crystals are transported into filter 1. Inside filter 1, there is a 500-mesh sintered plate 1062 to prevent crystal leakage. The residual crystallization solution leaks out during crystallization and flows through the sintered plate 1062 into the liquid extraction system 4, returning to crystallizer 2 for reuse.

[0029] Acetone is introduced to wash the crystals, while nitrogen system 3 performs backflushing. After a certain period of time, the crystal washing and nitrogen system 3 stop operating, and air system 5 starts to extract residual gas to dry the crystals as much as possible.

[0030] A support ring 1061 is fixedly installed inside the filter 1. A sintered plate 1062 is fixedly connected to the top surface of the support ring 1061 by bolts. A support ring 1063 is fixedly installed inside the filter 1. A sieve plate 1064 is provided on the top surface of the support ring 1063. The sieve plate 1064 is located on the top surface of the sintered plate 1062. Two drive components are provided at the bottom of the support ring 1063.

[0031] The drive assembly includes a protective box 1065 fixedly installed on the bottom surface of the support ring 1063. A movable rod 1066 is slidably connected inside the protective box 1065. The top end of the movable rod 1066 passes through the support ring 1063 and is fixedly connected to the screen plate 1064. When the movable rod 1066 moves up and down, it will drive the screen plate 1064 to move up and down.

[0032] A first spring 1067 is fixedly installed at the bottom of the movable rod 1066, and the first spring 1067 is fixedly connected to the bottom surface of the support ring 1063. A movable wheel 1068 is rotatably connected to the bottom end of the movable rod 1066. When the movable rod 1066 rises, it will compress the first spring 1067.

[0033] The filter 1 is internally connected to a first rotating shaft 1070, which passes through the interior of two protective boxes 1065. Cams 1069 are fixedly installed on both sides of the outer surface of the first rotating shaft 1070 inside the two protective boxes 1065. The cams 1069 are tumblingly connected to the movable wheel 1068. When the first rotating shaft 1070 drives the two cams 1069 to rotate, their contour curves contact the movable wheel 1068, pushing the movable wheel 1068 to move up and down in the vertical direction. This causes the two movable rods 1066 to drive the sieve plate 1064 to move up and down reciprocally. When the crystallized crystals fall onto the sieve plate 1064, the up-and-down movement of the sieve plate 1064 causes the crystals to shake. During the shaking process, the crystals fall onto the sintering plate 1062.

[0034] A first motor 106 is fixedly installed on the left side of the outer surface of the filter 1. One end of the first rotating shaft 1070 extends to the outside of the filter 1, and the output shaft of the first motor 106 is fixedly connected to the end of the first rotating shaft 1070 extending to the outside of the filter 1. The first motor 106 is powered by an external power source. When the first motor 106 is powered on, it will drive the first rotating shaft 1070 to rotate.

[0035] A fixed box 1074 is fixedly installed inside the filter 1. The fixed box 1074 is located between the sieve plate 1064 and the sintering plate 1062. A second rotating shaft 1073 is rotatably connected inside the filter 1. A protective box 1065 is sleeved on the outer end of the second rotating shaft 1073. A first bevel gear 1075 is fixedly installed on the side of the outer surface of the second rotating shaft 1073 inside the fixed box 1074. A second motor 107 is fixedly installed on the left side of the outer surface of the filter 1. One end of the second rotating shaft 1073 extends to the outside of the filter 1. The output shaft of the second motor 107 is fixedly connected to the end of the second rotating shaft 1073 that extends to the outside of the filter 1.

[0036] The second motor 107 is powered by an external power source. When the second motor 107 is powered on, it can drive the second rotating shaft 1073 to rotate.

[0037] A rotating rod 1077 is rotatably connected to the inner bottom surface of the fixed box 1074. One end of the rotating rod 1077 is located inside the fixed box 1074 and a second bevel gear 1076 is fixedly installed thereon. The other end of the rotating rod 1077 is located outside the fixed box 1074 and a connecting plate 1071 is fixedly installed thereon. The second bevel gear 1076 meshes with the first bevel gear 1075. When the second motor 107 drives the second rotating shaft 1073 to rotate, the first bevel gear 1075 will drive the second bevel gear 1076 to rotate, which will drive the rotating rod 1077 and the connecting plate 1071 to rotate.

[0038] A telescopic sleeve 1072 is fixedly installed on the bottom surface of the connecting plate 1071. A brush plate 1082 is slidably connected inside the telescopic sleeve 1072. A second spring 1081 is fixedly installed on one side of the inner wall of the telescopic sleeve 1072, and the second spring 1081 is fixedly connected to the brush plate 1082. In the normal state, the brush plate 1082 is inside the telescopic sleeve 1072. When the connecting plate 1071 drives the telescopic sleeve 1072 to rotate, the centrifugal force generated by the rotation will push the brush plate 1082... The brush plate 1082 is thrown out from inside the telescopic sleeve 1072 and stretches the second spring 1081. The brush plate 1082, thrown out by centrifugal force, will contact the top surface of the sintering plate 1062. The bristles of the brush plate 1082 will wipe and clean the top surface of the sintering plate 1062 to remove residual crystals. When the connecting plate 1071 stops rotating, the stretched second spring 1081 will drive the brush plate 1082 back into the telescopic sleeve 1072.

[0039] A crystallization tube 101 is fixedly installed on the left side of the outer surface of the filter 1. The crystals in the crystallization tank 2 and the acetone in the acetone system 6 can enter the filter 1 through the crystallization tube 101. An air pipe 103 is fixedly installed on the left side of the outer surface of the filter 1. The air pipe 103 is connected to the air system 5 through a pipeline so as to draw air out of the filter 1.

[0040] A nitrogen pipe 102 is fixedly installed on the right side of the outer surface of the filter 1. The nitrogen pipe 102 is connected to the nitrogen system 3 through a pipe so that nitrogen can be used for backflushing. A liquid extraction pipe 104 is fixedly installed on the bottom surface of the filter 1. The liquid extraction pipe 104 is connected to the liquid extraction system 4 through a pipe. The crystallization stock solution will then enter the liquid extraction system 4 through the liquid extraction pipe 104 and the pipe connected to it, and the liquid extraction system 4 will transfer the crystallization stock solution back to the crystallization tank 2. A connecting cover 105 is provided on the top surface of the filter 1.

[0041] The working principle of this utility model is as follows: After crystallization in the crystallization tank 2, the crystals are transported into the filter 1 through the crystallization tube 101. The first motor 106 drives the rotating shaft to rotate, which in turn drives the two cams 1069 to rotate. Their contour curves contact the movable wheel 1068, pushing the movable wheel 1068 to move up and down in the vertical direction. This causes the two movable rods 1066 to drive the sieve plate 1064 to move up and down reciprocally. When the crystallized crystals fall onto the sieve plate 1064, the up-and-down movement of the sieve plate 1064 will cause the crystals to shake. During the shaking process, the crystals will fall onto the sintering plate 1062, which prevents the crystals from leaking out.

[0042] The sintering plate 1062 allows residual crystallization solution to leak out during crystallization, and the solution leaks into the extraction system 4 through the sintering plate 1062 and the extraction pipe 104. The extraction system 4 then returns the solution to the crystallization tank 2 for reuse. The acetone system 6 introduces acetone through the crystallization pipe 101 to wash the crystals. At the same time, the nitrogen system 3 performs a backflushing operation through the nitrogen pipe 102. After a certain period of time, the crystal washing and nitrogen system 3 stop operating. The air system 5 then starts to extract residual gas through the air pipe 103 to dry the crystals as much as possible.

[0043] The second motor 107 drives the second rotating shaft 1073 to rotate, causing the first bevel gear 1075 to drive the second bevel gear 1076 to rotate. The rotating rod 1077 then drives the connecting plate 1071 to rotate. The centrifugal force generated by the rotation will throw the brush plate 1082 out from the telescopic sleeve 1072 and stretch the second spring 1081. The brush plate 1082 thrown out by the centrifugal force will then contact the top surface of the sintering plate 1062. The bristles of the brush plate 1082 will wipe and clean the top surface of the sintering plate 1062 to remove residual crystals.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
