Description

Technical Field

[0001] This utility model relates to the field of silica production technology, specifically to a washing and dehydration device for silica synthesis liquid. Background Technology

[0002] Silica, also known as hydrated silica, is currently produced mainly through fumed silica and precipitation methods. It is primarily used as a reinforcing agent for silicone rubber, a thickener for coatings and unsaturated resins, a reinforcing agent for natural and synthetic rubber, and an abrasive in toothpaste.

[0003] Currently, in the production process of silica, the silica synthesis liquor needs to be washed and filtered using a pressure filter. During the washing process, the filtrate is discharged by applying pressure, while the solids (silica) are retained. At the same time, washing water is introduced for replacement washing. Some solid silica may accumulate due to precipitation, which may prevent effective washing and affect the quality of the finished product. This has certain drawbacks. Therefore, we propose a washing and dehydration device for silica synthesis liquor. Utility Model Content

[0004] The purpose of this invention is to provide a washing and dehydration device for silica synthesis liquid to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a washing and dehydration device for silica synthesis liquid, comprising a tank and a support leg fixed to the bottom of the tank, a tank cover is provided on the right side of the tank, an extrusion mixing assembly is provided inside and on the left side of the tank, a water inlet pipe is provided at the top of the tank, a sewage discharge pipe is provided at the bottom of the tank, and a one-way assembly is provided inside both the water inlet pipe and the sewage discharge pipe;

[0006] The extrusion mixing assembly includes:

[0007] The rotating disc is used to drive the paddle to rotate and stir the inside of the tank;

[0008] The pressure plate is used to drive the rotating plate to move left and right.

[0009] The rotating rod is used to drive the rotating disk to rotate.

[0010] Electric push rod, used to drive the pressure plate to move left and right.

[0011] Preferably, the electric push rod is fixed to the left side of the tank body, the output shaft of the electric push rod passes through the left side of the tank body, the output shaft of the electric push rod is fixed to the left side of the pressure plate, a rubber ring is provided on the outer surface of the pressure plate, the pressure plate is piston-connected to the inner wall of the tank body, a groove is provided on the right side of the pressure plate, a rotating disk is rotatably installed on the inner side of the groove on the right side of the pressure plate, a rotating rod is rotatably installed on the left side of the rotating disk, the rotating rod passes through the pressure plate and the output shaft of the electric push rod, the rotating rod is rotatably connected to the pressure plate, a spiral groove is provided on the surface of the rotating rod, a transverse groove is provided at the top of the output shaft of the electric push rod, an insert rod is fixed on the inner wall of the tank body, and the bottom of the insert rod passes through the transverse groove. The groove is slidably installed in a spiral groove. The paddle passes through the right side of the rotating disk and is slidably connected to the rotating disk. A support spring is fixed to the inner wall of the rotating disk. The end of the support spring away from the rotating disk is fixed to the left side of the paddle. By activating the electric push rod, the electric push rod can drive the pressure plate and the rotating disk to move left and right in the tank. During the left and right movement of the pressure plate and the rotating disk, the insert rod slides in the spiral groove on the surface of the rotating rod, so that the rotating rod drives the rotating disk to rotate. The rotating disk drives the paddle to rotate, which agitates the inside of the tank, effectively preventing the accumulation of solid silica and affecting the washing effect. During the filtration process, the paddle can be completely embedded in the rotating disk, so as not to affect the normal filtration operation.

[0012] Preferably, the unidirectional component includes a baffle made of rubber. A vertical rod is fixed to the bottom of the baffle. A fixing plate is fixed to the inner wall of the water inlet pipe. The vertical rod passes through the fixing plate and is slidably connected to it. A compression spring is fixed to the bottom of the fixing plate. The end of the compression spring away from the fixing plate is fixed to the vertical rod. When the pressure plate and the rotating plate move to the left inside the tank, the pressure plate connected to the piston can be used to pump the tank through the water inlet pipe and the drain pipe. At this time, the baffle inside the drain pipe blocks the drain pipe, preventing the tank from being pumped through the drain pipe. The baffle inside the inlet pipe is pulled downwards by force, so that the baffle can no longer block the inlet pipe, and the washing water can be drawn into the tank for washing. When the pressure plate and rotating plate move to the right inside the tank, the baffle inside the inlet pipe blocks the inlet pipe due to pressure and the action of the compression spring, so the washing water cannot be discharged through the inlet pipe. Under pressure, the baffle inside the drain pipe is pushed downwards, so the baffle can no longer block the drain pipe, and the washing water can be discharged through the drain pipe, thus realizing the washing and filtration operation with high efficiency.

[0013] Preferably, a filter plate is fixed on the inner wall of the tank. The filter plate is located at the connection between the drain pipe and the tank. Washing water can pass through the filter plate, while silica cannot pass through the filter plate, thus remaining in the tank. After the washing and dehydration process is completed, the operator only needs to open the tank lid to take out the processed silica.

[0014] Compared with the prior art, the present invention provides a washing and dehydration device for silica synthesis liquor, which has the following advantages:

[0015] 1. The washing and dehydration device for the silica synthesis liquid, through the set extrusion mixing component, activates the electric push rod, which drives the pressure plate and rotating plate to move left and right in the tank. During the left and right movement of the pressure plate and rotating plate, the insert rod slides in the spiral groove on the surface of the rotating rod, causing the rotating rod to drive the rotating plate to rotate. The rotating plate drives the paddle to rotate, which agitates the inside of the tank, effectively preventing the accumulation of solid silica and affecting the washing effect. During the pressure filtration process, the paddle can be completely embedded in the rotating plate, so as not to affect the normal pressure filtration operation.

[0016] 2. The washing and dewatering device for the silica synthesis liquid, through the set extrusion mixing component and unidirectional component, allows washing water to be drawn through the water inlet pipe for washing when the pressure plate and rotating plate move to the left in the tank. When the pressure plate and rotating plate move to the right in the tank, the silica is extruded and dewatered, and the washing water is discharged from the drain pipe. The whole unit is an integrated operation, requiring less manual operation, effectively improving work efficiency and being easy to use. Attached Figure Description

[0023] like Figures 1-5As shown, this utility model provides a technical solution: a washing and dehydration device for silica synthesis liquid, including a tank 1 and a support leg 2 fixed to the bottom of the tank 1. A tank cover 5 is provided on the right side of the tank 1. An extrusion mixing assembly 3 is provided inside the tank 1 and on the left side. A water inlet pipe 6 is provided at the top of the tank 1 and a drain pipe 7 is provided at the bottom of the tank 1. A one-way assembly 4 is provided inside both the water inlet pipe 6 and the drain pipe 7. The extrusion mixing assembly 3 includes: a rotating disk 31, a paddle 32, a pressure plate 33, a rotating rod 34, an electric push rod 35, a spiral groove 36, a transverse groove 37, an insertion rod 38, and a support spring 39.

[0024] An electric push rod 35 is fixed to the left side of the tank body 1. The output shaft of the electric push rod 35 passes through the left side of the tank body 1 and is fixed to the left side of the pressure plate 33. A rubber ring is provided on the outer surface of the pressure plate 33. The pressure plate 33 is piston-connected to the inner wall of the tank body 1. A groove is provided on the right side of the pressure plate 33. A rotating disk 31 is rotatably installed on the inner side of the groove on the right side of the pressure plate 33. A rotating rod 34 is rotatably installed on the left side of the rotating disk 31. The rotating rod 34 passes through the pressure plate 33 and the output shaft of the electric push rod 35 and is rotatably connected to the pressure plate 33. A spiral groove 36 is provided on the surface of the rotating rod 34. A transverse groove 37 is provided at the top of the output shaft of the electric push rod 35. An insert rod 38 is fixed on the inner wall of the tank body 1. The bottom of the insert rod 38 passes through the transverse groove 37 and is slidably installed in the spiral groove 36. Inside, the paddle 32 passes through the right side of the rotating disk 31 and is slidably connected to the rotating disk 31. A support spring 39 is fixed to the inner wall of the rotating disk 31. The end of the support spring 39 away from the rotating disk 31 is fixed to the left side of the paddle 32. By activating the electric push rod 35, the electric push rod 35 can drive the pressure plate 33 and the rotating disk 31 to move left and right inside the tank 1. During the left and right movement of the pressure plate 33 and the rotating disk 31, the insert rod 38 slides in the spiral groove 36 on the surface of the rotating rod 34, so that the rotating rod 34 drives the rotating disk 31 to rotate. The rotating disk 31 drives the paddle 32 to rotate, which agitates the inside of the tank 1, effectively preventing the accumulation of solid silica and affecting the washing effect. During the filtration process, the paddle 32 can be completely embedded in the rotating disk 31, so as not to affect the normal filtration operation.

[0025] The one-way component 4 includes a baffle 41 made of rubber. A vertical rod 42 is fixed to the bottom of the baffle 41. A fixing plate 43 is fixed to the inner wall of the water inlet pipe 6. The vertical rod 42 passes through the fixing plate 43 and is slidably connected to the fixing plate 43. A compression spring 44 is fixed to the bottom of the fixing plate 43. The end of the compression spring 44 away from the fixing plate 43 is fixed to the vertical rod 42. When the pressure plate 33 and the rotating plate 31 move to the left inside the tank 1, the pressure plate 33 connected by the piston can be used to pump through the water inlet pipe 6 and the drain pipe 7. At this time, the baffle 41 inside the drain pipe 7 blocks the drain pipe 7, preventing the tank 1 from being pumped through the drain pipe 7. The baffle 41 inside the water pipe 6 is pulled downward by the force, so that the baffle 41 can no longer block the water inlet pipe 6, and the washing water can be drawn into the tank 1 through the water inlet pipe 6 for washing operation. When the pressure plate 33 and the rotating plate 31 move to the right inside the tank 1, under the action of pressure and the compression spring 44, the baffle 41 inside the water inlet pipe 6 blocks the water inlet pipe 6, so the washing water cannot be discharged through the water inlet pipe 6. Under the action of pressure, the baffle 41 inside the drain pipe 7 is pushed downward, and the baffle 41 can no longer block the drain pipe 7, so the washing water can be discharged through the drain pipe 7, thus realizing the washing and pressure filtration operation with high efficiency.

[0026] A filter plate 8 is fixed on the inner wall of the tank 1. The filter plate 8 is located at the connection between the drain pipe 7 and the tank 1. The washing water can pass through the filter plate 8, while the silica cannot pass through the filter plate 8, so that it is retained in the tank 1. After the washing and dehydration process is completed, the staff only needs to open the tank cover 5 to take out the processed silica.

[0027] In this utility model, during use, the can lid 5 is opened, materials are added into the can body 1, the can lid 5 is closed, a receiving bucket is placed at the bottom of the drain pipe 7, and the water inlet pipe 6 is inserted into the washing water tank, with the water tank height consistent with the can body 1. The electric push rod 35 is started, and the output shaft of the electric push rod 35 drives the pressure plate 33 and the rotating plate 31 to move left and right inside the can body 1. During the left and right movement of the pressure plate 33 and the rotating plate 31, the insertion rod 38 slides in the spiral groove 36 on the surface of the rotating rod 34, causing the rotating rod 34 to drive the rotating plate 31 to rotate. The rotating plate 31 drives the paddle 32 to rotate, stirring the inside of the can body 1, effectively preventing the accumulation of solid silica sediment, which affects the washing effect. During the filter pressing process, the paddle 32 can be completely embedded in the rotating plate 31, so as not to affect the normal filter pressing operation.

[0028] When the pressure plate 33 and the rotating plate 31 move to the left inside the tank 1, the pressure plate 33, connected by a piston, can be drawn through the water inlet pipe 6 and the drain pipe 7. At this time, the baffle 41 inside the drain pipe 7 blocks the drain pipe 7, preventing the tank 1 from being drawn through the drain pipe 7. The baffle 41 inside the water inlet pipe 6 is pulled downward by the force, so that the baffle 41 can no longer block the water inlet pipe 6, and the washing water can be drawn into the tank 1 through the water inlet pipe 6 for washing operation. When the pressure plate 33 and the rotating plate 31 move to the right inside the tank 1, under the action of pressure and the compression spring 44, the baffle 41 inside the water inlet pipe 6 blocks the water inlet pipe 6, so the washing water cannot be discharged through the water inlet pipe 6. Under the action of pressure, the baffle 41 inside the drain pipe 7 is pushed downward, and the baffle 41 can no longer block the drain pipe 7, so the washing water can be discharged through the drain pipe 7, thereby realizing the washing and pressure filtration operation.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
