Description

Technical Field

[0001] This utility model relates to the field of carbon molecular sieve processing equipment, specifically a carbon molecular sieve extrusion equipment. Background Technology

[0002] Carbon molecular sieves are porous materials with carbon as the main component, featuring a highly developed microporous structure and precisely controlled pore size distribution. They separate mixed gases (such as nitrogen, oxygen, methane, etc.) through adsorption selectivity or molecular sieving effect, and are widely used in gas separation, purification, and storage.

[0003] Carbon molecular sieves are generally processed through a spiral extrusion cylinder during extrusion molding. The spiral extrusion cylinder is usually equipped with a spiral extrusion conveyor shaft, which is equipped with a spiral conveyor paddle. At the same time, an electric heating component is provided on the inner wall of the spiral extrusion cylinder. In addition, an extrusion end is provided at the outlet of the spiral extrusion cylinder, and a cutter is provided on the outer side of the end portion of the spiral conveyor paddle that passes through the axis of the extrusion end.

[0004] When using this spiral extrusion cylinder to extrude carbon molecular sieve raw materials into strips, the raw materials are fed into the spiral extrusion cylinder. Then, the spiral extrusion conveyor shaft is driven to rotate by starting the motor. When the spiral extrusion output shaft rotates, it drives the spiral conveyor paddle to rotate, which is used to extrude and push the raw materials into the spiral extrusion cylinder. At the same time, the electric heating component is connected to the power supply to heat the raw materials. Finally, after the raw materials are heated and melted, they are extruded from the end of the strip under the extrusion thrust of the spiral conveyor paddle. With the addition of a cutter that rotates simultaneously, the strip of carbon molecular sieve raw materials can be granulated.

[0005] The advantage of this spiral extrusion cylinder for processing carbon molecular sieve raw materials is that the overall structure is simple and easy to use and maintain; however, the problems and defects are also obvious. For example, the electric heating component installed inside the spiral extrusion cylinder directly heats and melts the raw material. Due to the difficulty in controlling the heating temperature of the electric heating component, the raw material near the inner wall of the spiral extrusion cylinder is easily scorched, which in turn affects the quality of the carbon molecular sieve strips extruded later.

[0006] In view of the problems in the background art mentioned above, the present invention aims to provide a carbon molecular sieve extrusion equipment. Utility Model Content

[0007] The purpose of this invention is to provide a carbon molecular sieve extrusion device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A carbon molecular sieve extrusion equipment, the carbon molecular sieve extrusion equipment comprising:

[0010] The hopper, extrusion cylinder, and pelletizing end are connected to the bottom of the hopper via a feeding pipe. A feeding valve is installed on the feeding pipe, and the bottom of the feeding pipe is connected to the inside of the extrusion cylinder.

[0011] The extrusion cylinder has a propulsion chamber inside, and a heat insulation layer is formed on the inner wall of the propulsion chamber. A propulsion assembly is installed inside the propulsion chamber. The pelletizing end is connected to the outlet of the extrusion cylinder. At the same time, a slicing assembly is installed at the outlet of the pelletizing end. The slicing assembly installed on one side of the pelletizing end is connected to the propulsion assembly set inside the extrusion cylinder.

[0012] In addition, both the inside of the extrusion cylinder and the pelletizing end are connected to a gas supply component for introducing clean hot air into the inside of the extrusion cylinder and the pelletizing end to ensure the molten state of the molecular sieve inside the extrusion cylinder and the pelletizing end.

[0013] As a further embodiment of this utility model: the propulsion assembly includes a servo motor, a gearbox, a spiral conveying shaft, a first spiral disk, a second spiral disk, and a third spiral disk. The servo motor and the gearbox are linearly arranged and installed on one side of the outer end of the extrusion cylinder. The output end of the servo motor is connected to the gearbox, and the output end of the gearbox is provided with a spiral conveying shaft. The spiral conveying shaft is rotatably installed inside the propulsion cavity formed by the extrusion cylinder. The spiral conveying shaft has the first spiral disk, the second spiral disk, and the third spiral disk installed sequentially inside the extrusion cylinder. The arrangement distance between the first spiral disk, the arrangement distance between the second spiral disk, and the arrangement distance between the third spiral disk are progressively increased.

[0014] As a further embodiment of this utility model: the cutting assembly includes a rotating drum, a cutter, and a bracket. The bracket is installed on the pelletizing end. One end of the rotating drum is connected to the end portion of the spiral conveyor shaft after passing through the pelletizing end. The other end of the rotating drum is rotatably mounted on the inner wall of the bracket via a positioning shaft at the axial position. The cutter is installed on the outer side of the rotating drum, and the cutter shaft and the outer side of the rotating drum are movably installed by means of thread and thread groove engagement.

[0015] As a further embodiment of this utility model: the air supply assembly includes an air pipe, an air heater, an air pump, and an air purifier. The air inlet of the air pump is connected to the air purifier, and the air outlet of the air pump is connected to the air inlet of the air heater. The air outlet of the air heater is connected to the air pipe, and an air valve is installed on the air pipe. The air outlet of the air pipe is simultaneously connected to the inside of the extrusion cylinder and the inside of the pelletizing end.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Compared with the current spiral extrusion cylinder, the carbon molecular sieve extrusion equipment described above has the following advantages:

[0018] It changes the original method of directly heating and melting the raw materials by setting an electric heating component inside the spiral extrusion cylinder, and instead innovatively sets a gas supply component on the outside of the extrusion cylinder;

[0019] The air supply component is designed to introduce clean hot air into the extrusion cylinder and the pelletizing end to ensure the molten state of the molecular sieve inside the extrusion cylinder and the pelletizing end. This prevents the molecular sieve from condensing, which would increase the thrust of the propulsion component and increase energy consumption. At the same time, it can also ensure the pelletizing efficiency of the molten molecular sieve at the pelletizing end.

[0020] Furthermore, the air supply components include air pipes, air heaters, air pumps, and air purifiers. Since the heating temperature of the incoming hot air can be easily controlled and evenly distributed inside the extrusion cylinder, there will be no situation where the electric heating components installed on the inner wall of the extrusion cylinder cause the raw materials at the edge of the inner wall of the extrusion cylinder to burn.

Detailed Implementation

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Example

[0027] Please see Figure 1 and Figure 2 The present invention provides a carbon molecular sieve extrusion equipment, which includes:

[0028] The equipment includes a hopper 3, an extrusion cylinder 6, and a pelletizing end 11. The hopper 3 is used to feed molten carbon molecular sieve raw materials. The bottom end of the hopper 3 is connected to a feeding pipe 5, and a feeding valve 4 is installed on the feeding pipe 5. The bottom end of the feeding pipe 5 is connected to the inside of the extrusion cylinder 6. The feeding pipe 5 is used to smoothly guide the molten carbon molecular sieve raw materials fed into the hopper 3 into the inside of the extrusion cylinder 6, while the feeding valve 4 installed on the feeding pipe 5 is used to control the feeding state of the raw materials.

[0029] The extrusion cylinder 6 has a propulsion chamber inside, and a heat insulation layer 17 is formed on the inner wall of the propulsion chamber. A propulsion assembly is installed inside the propulsion chamber. The pelletizing end 11 is connected to the outlet position of the extrusion cylinder 6. The propulsion assembly installed inside the extrusion cylinder 6 is used to extrude and push the carbon molecular sieve raw material entering the extrusion cylinder 6 to the pelletizing end 11 for extrusion strip forming. At the same time, a strip cutting assembly is installed at the outlet position of the pelletizing end 11. The strip cutting assembly installed on one side of the pelletizing end 11 is connected to the propulsion assembly set inside the extrusion cylinder 6. When the propulsion assembly is running, the strip cutting assembly will also run at the same time to cut the carbon molecular sieve strip formed at the pelletizing end 11 to the specified size according to the processing requirements.

[0030] In addition, both the inside of the extrusion cylinder 6 and the inside of the pelletizing end 11 are connected to an air supply component. The air supply component is used to introduce clean hot air into the inside of the extrusion cylinder 6 and the inside of the pelletizing end 11 to ensure the molten state of the molecular sieve inside the extrusion cylinder 6 and the inside of the pelletizing end 11. This avoids the molecular sieve from solidifying, which would increase the thrust of the propulsion component and increase energy consumption. At the same time, it can also ensure the pelletizing efficiency of the molten molecular sieve at the pelletizing end 11.

[0031] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the propulsion assembly includes a servo motor 1, a reduction gearbox 2, a spiral conveying shaft, a first spiral disk 18, a second spiral disk 19, and a third spiral disk 20. The servo motor 1 and the reduction gearbox 2 are linearly arranged and installed on one side of the outer end of the extrusion cylinder 6. The output end of the servo motor 1 is connected to the reduction gearbox 2. The output end of the reduction gearbox 2 is provided with a spiral conveying shaft. The spiral conveying shaft is rotatably installed inside the propulsion cavity formed by the extrusion cylinder 6. The spiral conveying shaft is sequentially installed with the first spiral disk 18, the second spiral disk 19, and the third spiral disk 20 inside the extrusion cylinder 6. The arrangement distance between the first spiral disks 18, the arrangement distance between the second spiral disks 19, and the arrangement distance between the third spiral disks 20 are progressively increased.

[0032] In an embodiment of this utility model, when the propulsion assembly is used to melt, propel, and extrude the molecular sieve raw material entering the feed valve 4 into strips, the servo motor 1 is started. The servo motor 1 outputs kinetic energy and transmits mechanical energy to the screw conveyor shaft through the reduction gearbox 2, causing the screw conveyor shaft to rotate. When the screw conveyor shaft rotates, the first spiral disk 18, the second spiral disk 19, and the third spiral disk 20, which are linearly arranged on the screw conveyor shaft, will rotate simultaneously to screw-extrude and push the incoming molecular sieve raw material. During the material conveying process, the hot air supplied by the air supply assembly can melt the molecular sieve raw material. Moreover, the thrust generated by the rotating first spiral disk 18, the second spiral disk 19, and the third spiral disk 20 gradually increases, and finally the molten molecular sieve raw material is extruded and pushed out from the pelletizing end 11 into strips.

[0033] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the slicing assembly includes a rotating drum 9, a cutter 8, and a bracket 7. The bracket 7 is mounted on the pelletizing end 11. One end of the rotating drum 9 is connected to the end portion of the spiral conveyor shaft after it passes through the pelletizing end 11. The other end of the rotating drum 9 is rotatably mounted on the inner wall of the bracket 7 via a positioning shaft 10 at the axial center position. The cutter 8 is mounted on the outer side of the rotating drum 9, and the axial center of the cutter 8 and the outer side of the rotating drum 9 are movably mounted by means of thread and thread groove engagement.

[0034] In an embodiment of this utility model, when the molecular sieve strips extruded from the pelletizing end 11 are pelletized according to processing requirements by the pelletizing assembly, the rotating drum 9 installed at one end of the rotating drum 9 will rotate when the screw conveyor shaft of the propulsion assembly rotates. When the rotating drum 9 rotates, the cutter 8 installed on the outside of the rotating drum 9 will rotate to pelletize the formed carbon molecular sieve strips. By adjusting the lateral distance of the cutter 8 on the rotating drum 9, the distance between the carbon molecular sieve strips can be changed.

[0035] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the air supply assembly includes an air pipe 12, an air heater 14, an air pump 15, and an air purifier 16. The air inlet of the air pump 15 is connected to the air purifier 16, and the air outlet of the air pump 15 is connected to the air inlet of the air heater 14. The air outlet of the air heater 14 is connected to the air pipe 12, and an air valve 13 is installed on the air pipe 12. The air outlet of the air pipe 12 is simultaneously connected to the inside of the extrusion cylinder 6 and the inside of the pelletizing end 11.

[0036] In an embodiment of this utility model, when the provided air supply component is used to simultaneously introduce high-temperature hot air into the extrusion cylinder 6 and the pelletizing end 11 to ensure the molten state of the carbon molecular sieve raw material, the power supply is simultaneously turned on to the air pump 15 and the air heater 14. After the air pump 15 is powered on, it generates a vacuum negative pressure, which draws the outside natural air into the air purifier 16. After being filtered and purified by the air purifier 16, it is delivered to the air heater 14.

[0037] Clean air is heated inside the air heater 14 and then delivered to the inside of the extrusion cylinder 6 and the pelletizing end 11 through the air pipe 12 to ensure the molten state of the carbon molecular sieve raw material inside the extrusion cylinder 6 and the air pipe 12.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
