Description

Technical Field

[0001] The utility model belongs to the field of filter pressing devices, in particular to a filter pressing device for producing activated alumina. Background Art

[0002] The filter press for activated alumina production is an auxiliary device used in the activated alumina production process to filter the material to separate the solid and liquid. It is widely used in the production field. The National Intellectual Property Office issued an authorization announcement on September 14, 2018, with the authorization announcement number CN207859535U: "A filter press for activated alumina production". The patent discloses a device for squeezing activated alumina and then filtering out the liquid therein. However, the device extrudes the activated alumina by alternating the up and down squeezing of the pressing plate and the left and right squeezing of the push plate. When the contact area between the pressing plate and the activated alumina is smaller than the area of ​​the activated alumina, and the contact area between the push plate and the activated alumina is smaller than the area of ​​the activated alumina, there is a dead angle for squeezing, resulting in insufficient squeezing, thereby affecting the filtration effect of the activated alumina; and in the process of squeezing the activated alumina, activated alumina cannot continue to be added to the working box, resulting in low filtration efficiency. Therefore, we designed a filter press device for activated alumina production. Utility Model Content

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0016] A filter press device for producing activated alumina, such as Figure 1 , 2As shown, it includes a box body 1, a plurality of supporting legs 2 are fixedly installed on the box body 1, and the supporting legs 2 are fixedly installed on the four corners of the bottom of the box body 1 respectively. A first transverse tube 3 is connected and installed on the box body 1, one end of the first transverse tube 3 is located inside the box body 1, and the other end of the first transverse tube 3 is located outside the box body 1 and is closed. A feed port 4 is provided on the first transverse tube 3, and a liquid outlet 5 and a discharge port 10 are provided on the box body 1. The liquid outlet 5 is located at the bottom of the box body 1, and the discharge port 10 is located on the left side of the box body 1. It is characterized in that: one end of the first transverse tube 3 located inside the box body 1 is rotatably connected to one end of the second transverse tube 6 through a sealed bearing, the inner diameter of the first transverse tube 3 is the same as the inner diameter of the second transverse tube 6, the other end of the second transverse tube 6 is rotatably connected to the inner wall of the box body 1 through a sealed bearing, and the second transverse tube 6 is connected to the inner wall of the box body 1 through a sealed bearing. 0 is communicated with the outside world, a plurality of filter holes 11 are provided on the side wall of the second transverse tube 6, a first motor 7 is fixedly installed on the closed end of the first transverse tube 3, an output shaft of the first motor 7 extends into the first transverse tube 3 and a first rotating shaft 8 is fixedly installed, an output shaft of the first motor 7 passes through a reserved hole on the first transverse tube 3, and is rotatably installed in the reserved hole through a sealed bearing, a spiral blade 9 is fixedly installed on the outer periphery of the first rotating shaft 8, the first transverse tube 3, the second transverse tube 6, the first motor 7, the first rotating shaft 8 and the spiral blade 9 are coaxially arranged, the outer periphery of the spiral blade 9 is in sliding contact with the inner periphery of the first transverse tube 3 and the second transverse tube 6, the spiral pitch of the spiral blade 9 close to the feed port 4 is large, and the spiral pitch of the spiral blade 9 away from the feed port 4 is small, that is, the spiral pitch of the spiral blade 9 decreases from right to left. The utility model has a simple structure and ingenious conception. The activated alumina is extruded more fully by the spiral blades 9, avoiding the existence of extrusion dead corners, thereby enhancing the extrusion effect of the activated alumina. In addition, during the extrusion process, activated alumina can be continuously added to the first transverse tube 3 and the second transverse tube 6, which can meet market demand and is suitable for promotion. When using the utility model, the first motor 7 is started, and the activated alumina is put into the first transverse tube 3 through the feed port 4. The output shaft of the first motor 7 rotates to drive the spiral blade 9 to rotate through the first rotating shaft 8. While the spiral blade 9 rotates, the activated alumina is transported from right to left into the second transverse tube 6, and then transported from right to left along the second transverse tube 6. During the transportation process, since the spiral pitch of the spiral blade 9 decreases from right to left, the activated alumina is continuously squeezed when it is transported from right to left under the action of the spiral blade 9. The squeezed liquid is discharged from the second transverse tube 6 through the filter hole 11, enters the bottom of the box body 1, and then discharged from the box body 1 through the liquid outlet 5 at the bottom of the box body 1. The activated alumina after extrusion is discharged from the box body 1 through the discharge port 10 on the left side of the box body 1.

[0017] Specifically, as shown in the figure, a mounting plate 21 is movably installed in the box body 1 described in this embodiment through several spring rods 20, the fixed end of the spring rod 20 is fixedly connected to the inner wall of the box body 1, the movable end of the spring rod 20 is fixedly connected to one side of the mounting plate 21, and several cleaning needles 22 are fixedly installed on the side of the mounting plate 21 close to the second transverse tube 6. A driving device for driving the second transverse tube 6 to rotate is provided on the box body 1. When the filter holes 11 on the second transverse tube 6 rotate to the upper side, the cleaning needles 22 correspond one by one to the filter holes 11 on the upper side and are inserted into the corresponding filter holes 11. The second transverse tube 6 is driven to rotate by the driving device. At the same time, the filter hole 11 on the second transverse tube 6 revolves around the axis of the second transverse tube 6. When the filter hole 11 rotates to the bottom, it is easier for the liquid in the second transverse tube 6 to be discharged through the filter hole 11. Under the pushing action of the inner wall of the filter hole 11 and the guiding action of the inclined surface on the cleaning needle 22, the cleaning needle 22 is pushed to move upward. The upward movement of the cleaning needle 22 drives the mounting plate 21 to move upward, and the movable ends of several spring rods 20 are shortened. After the cleaning needle 22 is completely moved out of the corresponding filter hole 11, under the elastic force of the spring rod 20, the tip of the cleaning needle 22 abuts against and contacts the outer periphery of the second transverse tube 6 until the cleaning needle 22 is aligned with the next filter hole 11. Under the elastic force of the spring rod 22, the mounting plate 21 and the cleaning needle 22 move downward, and the cleaning needle 22 is inserted into the aligned filter hole 11 to clean up the aluminum oxide stuck in the filter hole 11 to prevent the filter hole 11 from being blocked, thereby preventing the squeezed liquid from being discharged from the filter hole 11.

[0018] Specifically, as shown in the figure, the driving device of this embodiment includes a second motor 30, which is fixedly mounted on the housing 1, and a gear 32 is fixedly mounted on the output shaft of the second motor 30 through a second rotating shaft 31, and the output shaft of the second motor 30 and one end of the second rotating shaft 31 extend into the same reserved hole on the housing 1 respectively, and are rotatably mounted in the reserved hole through a sealed bearing, and one end of the second rotating shaft 31 is coaxial and fixedly connected with the output shaft of the second motor 30, and the other end of the second rotating shaft 31 is coaxial and fixedly connected with the gear 32, and a coaxial gear ring 33 is fixedly mounted on the outer periphery of the second transverse tube 6, and the gear 32 is meshed with the gear ring 33. When the second motor 30 is started, the output shaft of the second motor 30 rotates to drive the gear 32 to rotate through the second rotating shaft 31, and the gear 32 rotates to drive the gear ring 33 to rotate, thereby driving the second transverse tube 6 to rotate.

[0019] Further, as shown in the figure, the discharge port 10 of the present embodiment is provided with a first baffle 40, the first baffle 40 and the side of the box body 1 close to each other are in airtight sliding contact cooperation, a plurality of extrusion outlets 41 are provided on the first baffle 40, one side of the first baffle 40 is fixedly connected to one end of a first electric push rod 42, the other end of the first electric push rod 42 is fixedly installed on the box body 1, the movable end of the first electric push rod 42 is fixedly connected to the upper side of the first baffle 40, and the fixed end of the first electric push rod 42 is connected to the connecting plate 43. The first baffle 40 is fixedly connected to the housing 1, and a second baffle 44 is provided in airtight sliding contact with the side of the first baffle 40 away from the discharge port 10.

One side of the second baffle 44 is fixedly connected to one end of a second electric push rod 45, and the other end of the second electric push rod 45 is fixedly installed on the housing 1. The movable end of the second electric push rod 45 is fixedly connected to the upper side of the second baffle 44, and the fixed end of the second electric push rod 45 is fixedly connected to the housing 1 through a connecting plate 43. When the first baffle 40 and the second baffle 44 completely seal the discharge port 10, the alumina cannot be discharged in the second transverse tube 6; the movable end of the second electric push rod 45 is controlled to be shortened, and the movable end of the second electric push rod 45 drives the second baffle 44 to move upward until the second baffle 44 no longer blocks the extrusion discharge port 41. At this time, the alumina in the second transverse tube 6 can be extruded and discharged through the extrusion discharge port 41, thereby further increasing the extrusion filtration effect of the alumina; the movable ends of the first electric push rod 42 and the second electric push rod 45 are controlled to be shortened, thereby driving the first baffle 40 and the second baffle 44 to move upward until the first baffle 40 and the second baffle 44 do not block the discharge port 10. At this time, the activated alumina can be directly discharged through the discharge port 10; or when the first transverse tube 3 and the second transverse tube 6 are cleaned, the dirt after cleaning can be discharged through the discharge port 10.

[0020] Further, as shown in the figure, the inner circumference of the feed port 4 in this embodiment is connected to a feed hopper 50.
