Description

Technical Field

[0001] The utility model relates to the technical field of sodium methoxide production, in particular to a solid-liquid separation device for sodium methoxide production. Background Art

[0002] Sodium methoxide is an organic compound and a hazardous chemical. It is mainly used in the pharmaceutical industry and organic synthesis as a condensation agent, chemical reagent, catalyst for edible oil processing, etc. At present, the preparation of sodium methoxide mainly adopts the production sequence of alcoholization reaction, refining, drying and packaging. At present, the refining mainly adopts evaporation crystallization separation. However, since solid-liquid separation is required after the crystallization is completed, the solid-liquid separation method of sodium methoxide at this stage mainly relies on centrifuges. At present, centrifuges mainly rely on filters to filter water attached to the surface of crystals when separating sodium methoxide crystal suspensions. This means that the filter needs to be kept unobstructed. However, due to the centrifugal effect, the crystal grains are easily stuck on the filter, which reduces the filtering effect. Therefore, the machine has to be stopped for cleaning, which not only affects the processing efficiency, but also affects the quality stability of the product. In view of this, in-depth research on the above-mentioned issues led to the emergence of this case. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 The utility model provides an implementation scheme: in the refining process of sodium methoxide, it is necessary to separate the crystals of sodium methoxide into solids and liquids. At present, centrifuge is mainly used for centrifugal separation. However, the existing centrifuge tube-type separation device needs to use a filter screen to cooperate with centrifugal separation. However, after a long period of operation, the filter screen of the centrifuge is prone to produce crystal grains stuck in the filter screen. Therefore, the application discloses a solid-liquid separation device for sodium methoxide production. The equipment is supported by a horizontal base 1, and a support casing 2 is arranged on the horizontal base 1. The support casing 2 is used as the supporting body of the separation mechanism of the equipment. A separation rotary groove 3 is opened on the support casing 2. The separation rotary groove 3 is an operating space for separation rotation. A separation feed pipe 4 is connected to one end of the separation rotary groove 3. A separation motor 5 is arranged at the other end of the separation rotary groove 3 corresponding to the separation feed pipe 4. A separation outer cylinder 7 is arranged in the separation rotary groove 3 for discharging materials to the outside. The installed separation inner cylinder 6 is connected to the driving end of the separation motor 5, and the separation motor 5 is used to drive the separation inner cylinder 6 to rotate, so that the threaded propulsion plate 61 outside the separation inner cylinder 6 rotates, and then the threaded propulsion plate 61 propels the material to the unloading end of the separation outer cylinder 7. An inner isolation filter 62 is arranged at the end of the separation inner cylinder 6, and the crystal suspension is passed between the separation outer cylinder 7 and the separation inner cylinder 6. Under the rotation of the separation inner cylinder 6, the crystal suspension is pushed to the separation rotation side by the threaded propulsion plate 61. Under the action of centrifugal force, the water in the suspension is lighter in density than the crystal, and gathers in the middle of the separation inner cylinder 6. The inner isolation filter 62 is used to separate the material, so that the water enters the separation inner cylinder 6 and moves in the opposite direction of the crystal gathering in the separation inner cylinder 6. An outer isolation filter 71 is arranged on the separation outer cylinder 7, and the crystals are isolated by the outer isolation filter 71, so that the crystals are located between the separation inner cylinder 6 and the separation outer cylinder 7 and move out;

[0019] According to the instruction manual Figure 1-3It can be known that in order to clean the filter screens on the separation inner cylinder 6 and the separation outer cylinder 7, a fixed support shaft 63 is provided on the separation inner cylinder 6 and connected to the end of the separation rotary groove 3. The fixed support shaft 63 is fixed by the separation rotary groove 3. The L-shaped inflection plate 64 on the fixed support shaft 63 fixes the cleaning inner brush 65. The cleaning inner brush 65 is used to clean the inner isolation filter screen 62 when the separation inner cylinder 6 rotates. A synchronous rotation block 66 is provided on the outer wall of the separation inner cylinder 6 for driving the external synchronous cleaning brush 74 to perform synchronous linkage, so that the synchronous cleaning brush 74 cleans the external isolation filter screen 71.

[0020] As a preferred solution, further, a synchronization groove 72 is provided on the outer side of the separation outer cylinder 7, and a synchronization seat 73 of a cylindrical structure is assembled on the synchronization groove 72. The synchronization seat 73 can slide in the synchronization groove 72 and perform circular motion in the separation outer cylinder 7 through the synchronization seat 73.

[0021] As a preferred solution, further, a synchronous cleaning brush 74 is installed on the synchronous seat 73, and the brush head of the synchronous cleaning brush 74 contacts the outer radial position of the outer isolation filter 71. The synchronous seat 73 can drive the synchronous cleaning brush 74 to perform circular motion synchronously, thereby cleaning the outer isolation filter 71.

[0022] As a preferred solution, further, an induction magnetic block 75 is provided on the synchronous seat 73, and a synchronous magnetic block 76 is provided on the synchronous rotating block 66. The induction magnetic block 75 and the synchronous magnetic block 76 correspond in position and attract each other. The induction seat and the synchronous magnetic block 76 correspond to each other. During the rotation of the separation inner cylinder 6, the separation inner cylinder 6 drives the synchronous rotating block 66 to rotate, and then the synchronous rotating block 66 drives the synchronous magnetic block 76 to rotate, and then the induction magnetic block 75 rotates accordingly, and then drives the synchronous seat 73 to rotate.

[0023] As a preferred solution, further, a pair of limit rings 77 are provided on both sides of the synchronization groove 72 , and the pair of limit rings 77 are attached to the outer side of the synchronization seat 73 to prevent the synchronization seat 73 from being separated from the synchronization groove 72 .

[0024] From the above, it can be generally known that the solid-liquid separation device for sodium methoxide production is used for solid-liquid separation of crystals in the refining process of sodium methoxide. The crystals are separated into solid and liquid by a centrifugal device with a threaded structure. The solid phase crystals produced in the separation process move to one side, and the liquid phase material is separated to the other side. An inner isolation filter 62 and an outer isolation filter 71 are correspondingly arranged at the ends of the separation inner cylinder 6 and the separation outer cylinder 7, so as to realize solid-liquid separation. Cleaning brushes with internal and external structures are used to clean the inner cylinder and the outer cylinder to prevent crystal grains from clogging the mesh.
