Description

Technical Field

[0001] The present invention relates to the technical field of filter presses, and particularly to a hard oil plate filter press for nickel-removing catalysts. Background Art

[0002] Hard oil is a white or slightly yellowish waxy solid at room temperature, and is suitable for the production of stearic acid, stearate, nickel-removing catalysts, etc. Ordinary hydrogenated oil is used for soap production; soft hydrogenated oil can be used in the food industry after treatment.

[0003] In the prior art, there are certain deficiencies in the pressure filtration of hard oil. For example, a hard oil plate filter press for nickel-removing catalysts (publication number CN211864145U) is disclosed in a Chinese patent. Its technical solution includes a stirring tank and a pressure filtration tank. Two feeding ports are opened on the upper end surface of the stirring tank, and feeding hoppers are installed at the feeding ports. Coarse filtration components are installed inside the feeding ports. A stirring component is installed inside the stirring tank. A discharge bin is arranged below the stirring tank, and a discharge port is arranged at the bottom of the discharge bin. The pressure filtration tank is installed below the stirring tank. Its technical solution directly allows the material to be roughly filtered through the filtration component under the action of gravity during feeding, and then finely filtered by extrusion.

[0004] However, in actual use of its technical solution, since hard oil is usually solid at room temperature and is directly put into the device for pressure filtration, the filtration effect is lacking, the material is not easily fully filtered, and if the melted hard oil is directly put in for filtration, it is easy to slowly solidify during the filtration process, resulting in easy adhesion and condensation in the device, not easy to clean, and large material loss.

[0005] In view of the above problems, the present invention document proposes a hard oil plate filter press for nickel-removing catalysts. Summary of the Invention

[0006] The present invention provides a hard oil plate filter press for nickel-removing catalysts, which solves the deficiencies in the prior art.

[0007] The present invention provides the following technical solutions:

[0008] A hard oil plate filter press for nickel-removing catalysts, comprising:

[0009] An outer tank body and a support screw rod;

[0010] A filtering inner barrel, arranged inside the outer tank body. A heating head with an internal electric heating wire is fixedly installed at the bottom of the inner wall of the filtering inner barrel. A double-shaft motor is fixedly installed at the bottom of the outer tank body, and the top end of the output shaft of the double-shaft motor is fixedly connected to the bottom end of the filtering inner barrel;

[0011] The limit top plate is arranged above the outer tank body. One end of the limit top plate is threadedly connected to the support screw rod. Both sides of the bottom end of the limit top plate are fixedly connected with push rods. A support connecting plate is arranged between the two push rods. The push rods and the support connecting plate are slidably connected. The bottom end of the support connecting plate is fixedly connected with a detachable inner lining sleeve for fitting into the filter inner barrel.

[0012] The extrusion plate is fixedly connected to the bottom ends of the two push rods. The extrusion plate is located on the outer wall of the inner lining sleeve and is used for slidably sleeving between the outer tank body and the filter inner barrel. Two filter net plates for filtering are arranged at the bottom end of the outer tank body.

[0013] In a possible design, a plurality of heat conducting rods are fixedly connected to the outer wall of the heating head for conducting the heat of the heating head. The plurality of heat conducting rods are annularly distributed around the central axis of the heating head, and the length of the heat conducting rods is less than the radius of the filter inner barrel.

[0014] In a possible design, an annular cushion plate is fixedly connected to the bottom of the inner wall of the outer tank body for supporting the filter inner barrel. The diameter of the annular cushion plate is equal to the diameter of the filter inner barrel. The double-shaft motor is located in the middle of the annular cushion plate.

[0015] In a possible design, the support connecting plate and the inner lining sleeve are fixedly connected by a plurality of screws. The outer wall of the inner lining sleeve is wrapped with rubber. The gap between the extrusion plate and the inner lining sleeve matches the wall thickness of the filter inner barrel.

[0016] In a possible design, the cross section of the outer tank body is an inverted "T" shaped structure. A servo motor is fixedly installed at the bottom of the outer tank body on one side of the double-shaft motor. The output shaft of the servo motor is fixedly connected to the bottom end of the support screw rod. The top end of the support screw rod is fixedly connected with a top block for blocking and limiting above the limit top plate. The limit top plate is designed in a "T" shaped structure.

[0017] In a possible design, a limit shaft sleeve is fixedly connected to the outer wall of the outer tank body. One end of the support screw rod is slidably sleeved in the limit shaft sleeve for supporting the support screw rod and blocking and limiting below the limit top plate.

[0018] In a possible design, a fan blade is fixedly installed at the bottom end of the output shaft of the double-shaft motor, and the fan blade is located between the two filter net plates. A receiving container for receiving materials is arranged at the bottom end of the outer tank body. A material blocking ring piece is fixedly connected to the bottom end of the outer tank body. The fan blade is located within the material blocking ring piece. The top end of the receiving container is clamped within the material blocking ring piece.

[0019] In a possible design, both the extrusion plate and the material blocking ring piece are designed in an annular structure, and rubber layers are arranged on both the inner wall and the outer wall of the extrusion plate.

[0020] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0021] In the present invention, a filtering inner barrel is arranged in the outer tank body for adding materials, and a heating head for heating is arranged in the filtering inner barrel. The heating head cooperates with a plurality of heat-conducting rods to quickly melt the hardened oil material after feeding, and the filtering inner barrel can rotate at a high speed under the drive of a double-axis motor, so that when the material is continuously melted, the melted material can be thrown out by centrifugal action for rapid filtration, thereby improving the filtration efficiency and ensuring that the material is in a melted state for a long time during the filtration process. With the cooperation of the supporting screw rod, the servo motor and the limiting top plate, the inner liner can be driven to descend to block the filter holes of the filtering inner barrel, and the extrusion plate squeezes the material to facilitate rapid and fine filtration through the filter screen plate. The filter press has the characteristics of high efficiency and easy cleaning, and reduces material loss.

[0022] In the present invention, by arranging fan blades at the bottom of the dual-axis motor, the dual-axis motor can synchronously drive the fan blades to rotate during the process of filtering and discharging the hardened oil, thereby accelerating the heat dissipation of the hardened oil, allowing it to quickly cool down and initially solidify, and conveniently using a receiving container to collect the cooled hardened oil and then move it away for transportation to prevent scalding of the staff. At the same time, the receiving container cooperates with the material blocking ring to prevent impurities from entering the hardened oil material when collecting the material, thereby preventing secondary pollution to the hardened oil, and providing good protection for the filtering of the hardened oil.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct communication or an indirect communication through an intermediate medium, so it should not be construed as a limitation to the embodiments of the present invention.

[0034] Embodiment 1

[0035] Refer to Figure 1-6 , a hard oil plate filter press for a nickel-removing catalyst in this embodiment includes:

[0036] Outer tank 1 and support screw rod 10;

[0037] Filter inner barrel 2, arranged inside outer tank 1. At the bottom of the inner wall of filter inner barrel 2, a heating head 3 with an internal heating wire is fixedly installed. At the bottom of outer tank 1, a biaxial motor 12 is fixedly installed, and the top end of the output shaft of biaxial motor 12 is fixedly connected to the bottom end of filter inner barrel 2;

[0038] Limit top plate 9, arranged above outer tank 1. One end of limit top plate 9 is threadedly connected to support screw rod 10. At both sides of the bottom end of limit top plate 9, pushing rods 8 are fixedly connected. Between the two pushing rods 8, a support connecting plate 7 is arranged. There is a sliding connection between pushing rod 8 and support connecting plate 7. At the bottom end of support connecting plate 7, a detachable inner lining sleeve 5 is fixedly connected for fitting into filter inner barrel 2;

[0039] The extrusion plate 6 is fixedly connected to the bottom ends of the two pushing rods 8. The extrusion plate 6 is located on the outer wall of the inner lining sleeve 5 and is used for slidingly sleeving between the outer tank body 1 and the filtering inner barrel 2. Two filter mesh plates 13 for filtering are arranged at the bottom end of the outer tank body 1.

[0040] Specifically, as Figure 4 shown, a plurality of heat conducting rods 4 are fixedly connected to the outer wall of the heating head 3 for conducting the heat of the heating head 3. The plurality of heat conducting rods 4 are annularly distributed around the central axis of the heating head 3, and the length of the heat conducting rod 4 is less than the radius of the filtering inner barrel 2. Through this design, when the hardened oil falls into the filtering inner barrel 2 and is melted by the heating head 3, the heat conducting rods 4 can increase the heating surface with the material, facilitating the rapid heating of the material. At the same time, when the filtering inner barrel 2 rotates, it can further accelerate the melting of the material.

[0041] Specifically, as Figure 3 shown, an annular backing plate 20 is fixedly connected to the bottom of the inner wall of the outer tank body 1 for supporting the filtering inner barrel 2. The diameter of the annular backing plate 20 is equal to the diameter of the filtering inner barrel 2. The dual-axis motor 12 is located in the middle of the annular backing plate 20. Through this design, the annular backing plate 20 can support the bottom of the filtering inner barrel 2, ensuring the stable rotation of the filtering inner barrel 2. At the same time, when the extrusion plate 6 descends to extrude the material, the annular backing plate 20 can ensure that the material is discharged through the filter mesh plate 13, preventing the material from entering the dual-axis motor 12, and at the same time providing good guarantee for the cleaning inside the outer tank body 1.

[0042] Specifically, as Figure 3 and Figure 5 shown, the support connecting plate 7 and the inner lining sleeve 5 are fixedly connected by a plurality of screws. The outer wall of the inner lining sleeve 5 is wrapped with rubber. The gap between the extrusion plate 6 and the inner lining sleeve 5 is matched with the wall thickness of the filtering inner barrel 2. Through this design, when the limit top plate 9 drives the inner lining sleeve 5 and the extrusion plate 6 to descend, the inner lining sleeve 5 is embedded into the filtering inner barrel 2 to block the filter holes, then the support connecting plate 7 is arranged on the filtering inner barrel 2, and the pushing rod 8 drives the extrusion plate 6 to continuously descend to extrude the material between the outer tank body 1 and the filtering inner barrel 2, so that it is filtered and discharged from the filter mesh plate 13.

[0043] Specifically, as Figure 5As shown, the cross-section of the outer tank body 1 is an inverted "T" - shaped structure. A servo motor 11 is fixedly installed at the bottom of the outer tank body 1 on one side of the dual - shaft motor 12. The output shaft of the servo motor 11 is fixedly connected to the bottom end of the support screw rod 10. By driving the support screw rod 10 to rotate through the servo motor 11, and since the support screw rod 10 is threadedly connected to the limit top plate 9, the limit top plate 9 can rise or fall under the action of the support screw rod 10 under the limiting effect of the outer tank body 1. The top end of the support screw rod 10 is fixedly connected with a top block 17, which is used to block and limit the upper part of the limit top plate 9, preventing the limit top plate 9 from rising excessively and directly detaching. Moreover, the top block 17 is connected to the top end of the support screw rod 10 through screws and can be disassembled, making it convenient to disassemble the limit top plate 9 and providing convenience for its maintenance. The limit top plate 9 is designed in a "T" - shaped structure. Through the structural design of the limit top plate 9, the limit top plate 9 has good structural stability when cooperating with the push rod 8, providing a good guarantee for the stable lifting of the extrusion plate 6.

[0044] Specifically, as Figure 1 and 6 shown, a limit bushing 16 is fixedly connected to the outer wall of the outer tank body 1. One end of the support screw rod 10 is slidably sleeved in the limit bushing 16, which is used to support the support screw rod 10 and block and limit the lower part of the limit top plate 9. By setting the limit bushing 16, the support screw rod 10 is kept connected to the outer tank body 1, enabling the support screw rod 10 to rotate stably and evenly under the drive of the servo motor 11, so as to better drive the push rod 8 to rise and fall, enabling the extrusion plate 6 to stably extrude the hardened oil material for filtration. At the same time, it can also prevent the extrusion plate 6 from descending excessively and scratching the bottom inner wall of the outer tank body 1, providing a good guarantee for its long - term safe use.

[0045] Specifically, as Figure 2 and Figure 5 shown, a fan blade 14 is fixedly installed at the bottom end of the output shaft of the dual - shaft motor 12, and the fan blade 14 is located between two filter net plates 13. A receiving container 18 for receiving materials is provided at the bottom end of the outer tank body 1. A material - blocking ring piece 15 is fixedly connected to the bottom end of the outer tank body 1. The fan blade 14 is located within the material - blocking ring piece 15, and the top end of the receiving container 18 is clamped within the material - blocking ring piece 15. By setting the material - blocking ring piece 15, when the material is extruded and discharged through the filter net plate 13, it can block the surrounding area, preventing the material from directly splashing into the surrounding environment. Moreover, the top end of the receiving container 18 can fit with the material - blocking ring piece 15, enabling the material to be directly discharged into the receiving container 18, facilitating unified collection using the receiving container 18 and preventing impurities from entering during the material - receiving process and causing secondary pollution.

[0046] Embodiment 2

[0047] Refer to Figure 1-7, A hard oil plate filter press for a nickel-removing catalyst in this embodiment includes:

[0048] An outer tank body 1 and a support screw rod 10;

[0049] A filter inner barrel 2 is arranged inside the outer tank body 1. At the bottom of the inner wall of the filter inner barrel 2, a heating head 3 with an internal electric heating wire is fixedly installed. At the bottom of the outer tank body 1, a double-shaft motor 12 is fixedly installed, and the top end of the output shaft of the double-shaft motor 12 is fixedly connected to the bottom end of the filter inner barrel 2;

[0050] A limit top plate 9 is arranged above the outer tank body 1. One end of the limit top plate 9 is threadedly connected to the support screw rod 10. Both sides of the bottom end of the limit top plate 9 are fixedly connected with push rods 8. A support connecting plate 7 is arranged between the two push rods 8. The push rod 8 and the support connecting plate 7 are slidably connected. The bottom end of the support connecting plate 7 is fixedly connected with a detachable inner lining sleeve 5 for fitting into the filter inner barrel 2;

[0051] An extrusion plate 6 is fixedly connected to the bottom ends of the two push rods 8. The extrusion plate 6 is located on the outer wall of the inner lining sleeve 5 and is used for slidably sleeving between the outer tank body 1 and the filter inner barrel 2. Two filter mesh plates 13 for filtration are arranged at the bottom end of the outer tank body 1.

[0052] Specifically, as Figure 4 shown, a plurality of heat conduction rods 4 are fixedly connected to the outer wall of the heating head 3 for conducting the heat of the heating head 3. The plurality of heat conduction rods 4 are annularly distributed around the central axis of the heating head 3, and the length of the heat conduction rod 4 is less than the radius of the filter inner barrel 2. Through this design, when the hard oil falls into the filter inner barrel 2 and is melted by the heating head 3, the heat conduction rods 4 can increase the heating surface with the material, facilitating the rapid heating of the material. At the same time, during the rotation of the filter inner barrel 2, the melting of the material can be further accelerated.

[0053] Specifically, as Figure 3 shown, an annular cushion plate 20 is fixedly connected to the bottom of the inner wall of the outer tank body 1 for supporting the filter inner barrel 2. The diameter of the annular cushion plate 20 is equal to the diameter of the filter inner barrel 2. The double-shaft motor 12 is located in the middle of the annular cushion plate 20. Through this design, the annular cushion plate 20 can support the bottom of the filter inner barrel 2, ensuring the stable rotation of the filter inner barrel 2. At the same time, when the extrusion plate 6 descends to extrude the material, the annular cushion plate 20 can ensure that the material is discharged through the filter mesh plate 13, preventing the material from entering the double-shaft motor 12, and providing good guarantee for the cleaning inside the outer tank body 1.

[0054] Specifically, as Figure 3 and Figure 5As shown, the support connecting plate 7 is fixedly connected to the inner lining sleeve 5 by a plurality of screws. The outer wall of the inner lining sleeve 5 is wrapped with rubber. The gap between the extrusion plate 6 and the inner lining sleeve 5 matches the wall thickness of the filter inner barrel 2. Through this design, when the limit top plate 9 drives the inner lining sleeve 5 and the extrusion plate 6 to descend, the inner lining sleeve 5 is inserted into the filter inner barrel 2 to block the filter holes. Then the support connecting plate 7 is arranged on the filter inner barrel 2, and the push rod 8 drives the extrusion plate 6 to continue to descend to extrude the material between the outer tank body 1 and the filter inner barrel 2, so that it is filtered and discharged from the filter mesh plate 13.

[0055] Specifically, as Figure 5 shown, the cross-section of the outer tank body 1 is an inverted "T" - shaped structure. A servo motor 11 located on one side of the double - shaft motor 12 is fixedly installed at the bottom of the outer tank body 1. The output shaft of the servo motor 11 is fixedly connected to the bottom end of the support screw rod 10. By driving the support screw rod 10 to rotate through the servo motor 11, and since the support screw rod 10 is threadedly connected to the limit top plate 9, the limit top plate 9 can rise or fall under the action of the support screw rod 10 under the limiting effect of the outer tank body 1. The top end of the support screw rod 10 is fixedly connected with a top block 17, which is used to block and limit the upper part of the limit top plate 9, preventing the limit top plate 9 from rising excessively and directly detaching. And the top block 17 is connected to the top end of the support screw rod 10 by screws and can be disassembled, making it convenient to disassemble the limit top plate 9 and providing convenience for its maintenance. The limit top plate 9 is designed in a "T" - shaped structure. Through the structural design of the limit top plate 9, the limit top plate 9 has good structural stability when cooperating with the push rod 8, providing a good guarantee for the stable lifting of the extrusion plate 6.

[0056] Specifically, as Figure 1 and 6 shown, a limit shaft sleeve 16 is fixedly connected to the outer wall of the outer tank body 1. One end of the support screw rod 10 is slidably sleeved in the limit shaft sleeve 16, which is used to support the support screw rod 10 and block and limit the lower part of the limit top plate 9. By setting the limit shaft sleeve 16, the support screw rod 10 is kept connected to the outer tank body 1, enabling the support screw rod 10 to rotate stably and evenly under the drive of the servo motor 11, so as to better drive the push rod 8 to rise and fall, enabling the extrusion plate 6 to stably extrude the hardened oil material for filtration. At the same time, it can also prevent the extrusion plate 6 from descending excessively and scratching the bottom inner wall of the outer tank body 1, providing a good guarantee for its long - term safe use.

[0057] Specifically, as Figure 2 and Figure 5As shown in the figure, a fan blade 14 is fixedly installed at the bottom end of the output shaft of the biaxial motor 12, and the fan blade 14 is located between two filter plates 13. A receiving container 18 for receiving materials is provided at the bottom end of the outer tank body 1. A baffle ring 15 is fixedly connected to the bottom end of the outer tank body 1. The fan blade 14 is located within the baffle ring 15. The top end of the receiving container 18 is clamped within the baffle ring 15. By providing the baffle ring 15, when the material is extruded and discharged through the filter plate 13, it can block the surrounding area to prevent the material from directly splashing into the surrounding environment. Moreover, the top end of the receiving container 18 can fit with the baffle ring 15, enabling the material to be directly discharged into the receiving container 18, facilitating unified collection using the receiving container 18 and preventing impurities from entering during the material receiving process, thus avoiding secondary pollution.

[0058] Specifically, as Figure 7 shown, both the extrusion plate 6 and the baffle ring 15 are designed with an annular structure. Rubber layers 19 are provided on both the inner wall and the outer wall of the extrusion plate 6. By providing rubber layers 19 on both the inner wall and the outer wall of the extrusion plate 6, a good closed surface can be formed when the extrusion plate 6 is extruded, facilitating sufficient extrusion of the material and enabling good filtration.

[0059] Working principle: During use, first, the hardened oil to be processed is put into the filter inner barrel 2 in the outer tank body 1. The heating wire in the heating head 3 is started to heat, so that the heat is conducted to the heating head 3 and several heat conducting rods 4 to heat the hardened oil to melt it. And the biaxial motor 12 is started to drive the filter inner barrel 2 to rotate. During the process of the heating head 3 heating the hardened oil, the melted hardened oil is thrown out through the filter holes on the filter inner barrel 2 under the centrifugal force, continuously filtering out the melted hardened oil. After the initial filtration of the hardened oil, the heating is stopped and the biaxial motor 12 is turned off to stop the rotation of the extrusion plate 6. Then the servo motor 11 is started to drive the support lead screw 10 to rotate forward, so that the limit top plate 9 is forced to descend. When the limit top plate 9 drives the inner lining sleeve 5 and the extrusion plate 6 to descend, the inner lining sleeve 5 is embedded into the filter inner barrel 2 to block the filter holes. Then the support connecting plate 7 is arranged on the filter inner barrel 2, and the push rod 8 drives the extrusion plate 6 to continuously descend to extrude the material between the outer tank body 1 and the filter inner barrel 2, so that it is filtered and discharged from the filter plate 13. Secondly, after the discharge is completed, the servo motor 11 is rotated in the reverse direction to rise, so that the inner lining sleeve 5 and the extrusion plate 6 are reset. Then the biaxial motor 12 is started to rotate to let the filter inner barrel 2 throw out the remaining hardened oil. At the same time, the fan blade 14 quickly dissipates the heat of the hardened oil collected by the receiving container 18 for subsequent transportation.

[0060] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention; without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
