Description

Technical Field

[0001] This invention relates to the field of chemical equipment technology, specifically to a crude methyl methacrylate monomer separation device and method. Background Technology

[0002] Methyl methacrylate (MMA) is an important chemical raw material widely used in synthetic resins, plastics, coatings, fibers, and adhesives. It possesses excellent transparency, weather resistance, and chemical corrosion resistance, making it widely applicable in the manufacture of transparent materials and optical devices. MMA can also be used to prepare hydrogels, artificial corneas, dental materials, and other products in the medical and biomedical fields. Besides industrial applications, MMA is also used as an additive in paints, a coating material for optical lenses, a dental filling material, and in the manufacture of handicrafts. It is important to note that MMA is a hazardous substance with an irritating odor; therefore, safety precautions must be taken during handling to avoid inhalation or contact with skin and eyes. Methyl methacrylate (MMA) crude monomer is an unpurified raw material used in the synthesis of MMA polymers or other related compounds. In specific applications, MMA crude monomer needs to be purified to obtain the required high-purity MMA. Currently, when separating mixtures containing crude MMA monomers, the extractant and the mixture need to be shaken. Although existing separation support devices can automatically shake the separatory funnel, the shaking and mixing efficiency is slow for larger separatory funnels, and the separatory funnel is not very stable. After shaking, the separatory funnel is prone to tilting, which affects the separation effect. Summary of the Invention

[0003] The purpose of this invention is to provide a crude methyl methacrylate monomer separation device and method to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a crude methyl methacrylate monomer separation device, comprising; Base; A fixed column is rotatably mounted on the top of one side of the column; The first annular shell is fixedly disposed on one side of the fixed post; The separatory funnel is inserted into the inner cavity of the first annular shell; A rotation limiting mechanism is provided at the top of the fixed column; A mixing mechanism is located on the other side of the column.

[0005] Preferably, a first rubber ring is rotatably provided on the inner side of the first annular shell via a bearing, and the first rubber ring is tightly attached to the outer wall of the separator.

[0006] Preferably, the rotation limiting mechanism includes: insert rods, with insert rods inserted into both the front and rear sides of the top end of the fixed column; a housing, fixedly disposed at the top end of the insert rods; a second annular shell, fixedly disposed on one side of the housing, and the second annular shell communicating with the inner cavity of the housing; a gear plate, rotatably disposed in the inner cavity of the second annular shell via a bearing; a second rubber ring, fixedly disposed on the inner side of the gear plate, and the second rubber ring extending out of the inner side of the second annular shell; a motor, fixedly disposed at the top end of the housing; and a first gear, the output end of the motor extending into the inner cavity of the housing and keyed to the first gear, and the outer wall of the first gear extending into the inner cavity of the second annular shell and meshing with the gear plate.

[0007] Preferably, the rotation limiting mechanism further includes: an insert block, a slot is provided on one side of the inner cavity of the fixing post, the insert block is inserted into the inner cavity of the slot, a plurality of slots are sequentially provided on one side of the insert rod from top to bottom, and one end of the insert block is inserted into the inner cavity of one of the slots; a spring is fixedly disposed between the insert block and the inner cavity of the slot; and a push block is fixedly disposed on the outside of the insert block, and one side of the push block extends out of the outside of the fixing post.

[0008] Preferably, one end of the insert is inclined downwards, and the insert is adapted to be inserted into the slot.

[0009] Preferably, the mixing mechanism includes: a rectangular shell fixedly disposed on one side of the column; a cylindrical shell fixedly disposed at the top of the rectangular shell and communicating with the inner cavity of the rectangular shell; a rotating shaft rotatably disposed on one side of the inner cavity of the cylindrical shell via a bearing, and one end of the rotating shaft extends out of one side of the column and is fixedly connected to one side of the fixed column; a second gear keyed to the outer wall of the rotating shaft; a guide rod fixedly disposed at the top of the inner cavity of the rectangular shell in the front-rear direction; a rack adapted to be fitted with the outer wall of the guide rod, and the rack meshes with the outer wall of the second gear; a shifting post fixedly disposed at the middle of the bottom end of the rack, and a strip-shaped hole is provided on one side of the shifting post; a reduction motor fixedly disposed on one side of the rectangular shell; a turntable, the output end of the reduction motor extending into the inner cavity of the rectangular shell and fixedly disposed thereon; and a shifting post fixedly disposed on the front side of the turntable, and the shifting post is adapted to be inserted into the inner cavity of the strip-shaped hole.

[0010] Preferably, the push pin is adapted to be inserted into the top of the inner cavity of the strip hole.

[0011] Step 1: Move the push block to one side so that the push block pushes the insert block to one side until the insert block disengages from the inner cavity of the slot and compresses the spring, thereby releasing the position restriction on the insert rod, so that the housing can drive the second annular shell to move upward, and thus be able to pick up the liquid separator placed in the first annular shell; Step 2: After placing the separatory funnel inside the first annular shell, move the shell downwards so that the second annular shell presses against the separatory funnel. During the downward movement of the insert rod, the inner cavity of the slot can push the inclined surface of the insert block to move the insert block to one side so that the insert rod can be inserted downwards. This makes the second annular shell press and fix itself on the outer wall of the separatory funnel. The cooperation between the slot and the insert block can limit the second annular shell to improve the stability of the separatory funnel. Step 3: Place the raw material into the separatory funnel and add the extractant. Start the motor and drive the first gear to rotate, so that the first gear drives the toothed disc to rotate clockwise around its own axis, so that the toothed disc drives the second rubber ring to rotate. Under the action of the friction of the second rubber ring, the separatory funnel can be rotated to accelerate the mixing of the solvent. Step 4: Control the start of the reduction motor. The reduction motor can drive the turntable to rotate clockwise around its own axis, so that the turntable drives the dial to rotate clockwise in a circular motion, so that the dial moves the inner wall of the strip hole back and forth, so that the dial drives the rack to move back and forth under the restriction of the guide rod, so that the rack drives the second gear to drive the rotating shaft to rotate clockwise and counterclockwise, thereby driving the fixed column to swing through the rotating shaft, further accelerating the mixing of the solvent and improving the separation efficiency.

[0012] The present invention provides a crude methyl methacrylate monomer separation device and method, the advantages of which are as follows: 1. The present invention can control the second annular shell to be pressed and fixed on the separator by setting a rotation limiting mechanism. Through the cooperation with the first annular shell and the first rubber ring, the separator can be driven to rotate when the second rubber ring is driven to rotate. The rotation makes the liquid raw materials evenly mixed. With the cooperation of the second annular shell and the first annular shell, the stability of the separator installation is improved, and the separator is prevented from tilting after movement. 2. The present invention has a mixing mechanism that can control the fixed column to swing back and forth significantly, thereby driving the rotating separator to swing, further improving the liquid mixing efficiency and accelerating the separation speed.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1, please refer to Figure 1-5 The present invention provides a technical solution: a crude methyl methacrylate monomer separation device, comprising: a base 1, a column 2, a fixed column 3, a first annular shell 4, a separating hopper 5, a rotating limiting mechanism 6, and a mixing mechanism 7; The column 2 is fixedly installed on one side of the top of the base 1, the fixed column 3 is rotatably installed on the top of one side of the column 2, the first annular shell 4 is fixedly installed on one side of the fixed column 3, the liquid separator 5 is inserted into the inner cavity of the first annular shell 4, the rotation limiting mechanism 6 is installed on the top of the fixed column 3, and the mixing mechanism 7 is installed on the other side of the column 2.

[0017] As a preferred embodiment, the inner side of the first annular shell 4 is further provided with a first rubber ring through a bearing, and the first rubber ring is tightly attached to the outer wall of the separator 5.

[0018] As a preferred embodiment, the rotation limiting mechanism 6 further includes: a rod 61, a housing 62, a second annular housing 63, a gear plate 64, a second rubber ring 65, a motor 66, a first gear 67, a plug block 68, a slot 69, a groove 610, a spring 611, and a push block 612. In order to drive the separatory funnel to rotate, the top of the fixed column 3 is inserted with insert rods 61 on both the front and rear sides. The housing 62 is fixedly installed on the top of the insert rods 61. The second annular shell 63 is fixedly installed on one side of the housing 62 and communicates with the inner cavity of the housing 62. The toothed disc 64 is rotatably installed in the inner cavity of the second annular shell 63 through a bearing. The second rubber ring 65 is fixedly installed on the inner side of the toothed disc 64 and extends out of the inner side of the second annular shell 63. The inner side of the second rubber ring 65 is tightly fixed to the separatory funnel 5. In order to drive the second rubber ring 65 to rotate, the motor 66 is fixedly mounted on the top of the housing 62. The output end of the motor 66 extends into the inner cavity of the housing 62 and is keyed to the first gear 67. The outer wall of the first gear 67 extends into the inner cavity of the second annular shell 63 and meshes with the gear plate 64. The motor 66 can drive the first gear 67 to rotate, so that the first gear 67 gear plate 64 rotates clockwise around its own axis, so that the gear plate 64 drives the second rubber ring 65 to rotate.

[0019] In order to restrict the position of the second annular shell 63, a slot 69 is provided on one side of the inner cavity of the fixing post 3. A plug 68 is inserted into the inner cavity of the slot 69. A number of slots 610 are provided on one side of the plug rod 61 from top to bottom, and one end of the plug 68 is inserted into the inner cavity of one of the slots 610. In order to limit the insertion rod 61, the spring 611 is fixedly installed between the inner cavity of the insertion block 68 and the slot 69. Under the elastic force of the spring 611, the insertion block 68 can be limited.

The push block 612 can move left and right on the outside of the fixing post 3.

[0020] As a preferred embodiment, one end of the insert 68 is inclined downwards, and the insert 68 is adapted to be inserted into the slot 610 so that the insert rod 61 can move downwards and be fixed.

[0021] As a preferred embodiment, the mixing mechanism 7 further includes: a rectangular shell 71, a cylindrical shell 72, a rotating shaft 73, a second gear 74, a guide rod 75, a rack 76, a shifting post 77, a strip hole 78, a reduction motor 79, a turntable 710, and a shifting post 711. In order to control the reciprocating rotation of the rotating shaft 73, the rectangular shell 71 is fixedly installed on one side of the column 2, the cylindrical shell 72 is fixedly installed on the top of the rectangular shell 71 and communicates with the inner cavity of the rectangular shell 71, and the rotating shaft 73 is rotatably installed on one side of the inner cavity of the cylindrical shell 72 through the bearing, and one end of the rotating shaft 73 extends out of one side of the column 2 and is fixedly connected to one side of the fixed column 3. In order to enable the second gear 74 to reciprocate, the second gear 74 is keyed to the outer wall of the rotating shaft 73, the guide rod 75 is fixedly installed at the top of the inner cavity of the rectangular shell 71 in the front-back direction, the rack 76 is adapted to be engaged with the outer wall of the guide rod 75, and the rack 76 meshes with the outer wall of the second gear 74. In order to drive the rack 76 to move, the actuating post 77 is fixedly set at the middle of the bottom end of the rack 76. A strip hole 78 is opened on one side of the actuating post 77. The reduction motor 79 is fixedly set on one side of the rectangular shell 71. The output end of the reduction motor 79 extends into the inner cavity of the rectangular shell 71 and is fixedly set with a turntable 710. The actuating post 711 is fixedly set on the front side of the turntable 710, and the actuating post 711 is adapted to be inserted into the inner cavity of the strip hole 78. The reduction motor 79 can drive the turntable 710 to rotate clockwise around its own axis, so that the turntable 710 drives the actuating post 711 to rotate clockwise, so that the actuating post 711 moves the inner wall of the strip hole 78 back and forth.

[0022] As a preferred option, the pin 711 is further adapted to be inserted into the top of the inner cavity of the strip hole 78, so that when the pin 711 rotates, it can drive the rack 76 to move to both sides by equal distances.

[0023] Step 1: Move the push block 612 to one side so that the push block 612 pushes the insert block 68 to one side until the insert block 68 disengages from the inner cavity of the slot 610 and compresses the spring 611, thereby releasing the position restriction on the insert rod 61, so that the housing 62 can drive the second annular housing 63 to move upward, and then the liquid separator 5 placed in the first annular housing 4 can be taken out. Step 2: After placing the separatory funnel 5 inside the first annular shell 4, move the shell 62 downward so that the second annular shell 63 is pressed against the separatory funnel 5. During the downward movement of the insertion rod 61, the inner cavity of the slot 610 can push the inclined surface of the insertion block 68 to move the insertion block 68 to one side so that the insertion rod 61 can be inserted downward, thereby pressing and fixing the second annular shell 63 against the outer wall of the separatory funnel 5. The cooperation between the slot 610 and the insertion block 68 can limit the second annular shell 63 to improve the stability of the separatory funnel 5. Step 3: Place the raw material into the separatory hopper 5 and add the extractant. Start the motor 66. The motor 66 can drive the first gear 67 to rotate, so that the first gear 67 can rotate the toothed disc 64 clockwise around its own axis, so that the toothed disc 64 can drive the second rubber ring 65 to rotate. Thus, under the action of the friction of the second rubber ring 65, the separatory hopper 5 can be rotated to accelerate the mixing of the solvent. Step 4: Start the geared motor 79. The geared motor 79 can drive the turntable 710 to rotate clockwise around its own axis, so that the turntable 710 drives the shifting pin 711 to rotate clockwise in a circular motion. This causes the shifting pin 711 to move the inner wall of the strip hole 78 back and forth, so that the shifting pin 77 drives the rack 76 to move back and forth under the restriction of the guide rod 75. This causes the rack 76 to drive the second gear 74 to drive the rotating shaft 73 to rotate clockwise and counterclockwise. This causes the fixed pin 3 to swing through the rotating shaft 73, further accelerating the mixing of the solvent and improving the separation efficiency.
