Description

Technical Field

[0001] The utility model relates to the technical field of slurry conveying, in particular to a novel single-screw extruder. Background Art

[0002] Single-screw extruder is a commonly used production equipment in the plastics industry. Due to its strong applicability, high stability, and strong pressure-building ability, it has gradually emerged in the battery ingredient industry. Conventional single-screw extruders are mainly supported by single-sided bearings. The bearings are connected to the screw in the transmission mechanism, driving the screw to rotate in the barrel. When the slurry is slowly conveyed through the screw, the slurry filled in the barrel gradually increases, supporting the screw and avoiding the friction caused by high-speed operation between the barrel and the screw. However, since the screw only relies on the bearings of the transmission mechanism to bear radial and axial forces during operation, the screw is prone to deviation during operation, resulting in increased friction between the screw and the inner wall of the barrel. In order to reduce friction, the machine needs to be operated at a low speed to convey the slurry after startup before it can be operated at a high speed. This has low efficiency and poor stability.

At the same time, the self-aligning bearing 6 facilitates the rotation of the screw rod 4, thereby improving the stability and smoothness of the rotation process of the screw rod 4.

[0054] On the basis of the above-mentioned embodiment, in a specific embodiment, one end of the barrel 3 away from the driving assembly 2 is fixedly connected to the frame 1 through a support bracket 7 .

[0055] In this embodiment, the support frame 7 cooperates with the driving assembly 2 to support the barrel, thereby improving the supporting strength.

[0056] Specifically, the barrel 3 is connected to the support frame 7 by a clamp, which is convenient for installation and disassembly.

[0057] Specifically, Fig. 9 As shown, the bearing seat 5 is flange-connected to the barrel 3 to improve the connection strength and sealing performance.

[0058] Based on the above implementation, in a specific implementation, as Figure 1 , Figure 6 and Fig. 9 As shown, the bearing assembly further includes a seal, which is disposed between the bearing seat 5 and the barrel 3 .

[0059] In this embodiment, a seal is provided between the bearing assembly and the barrel 3 to improve the sealing performance between the bearing assembly and the barrel 3 and prevent slurry leakage.

[0060] Based on the above implementation, in a specific implementation, as Figures 6 to 10 As shown, the sealing member includes a connecting plate 8, a first sealing block 9 and a second sealing block 10, wherein the connecting plate 8 is arranged between the bearing seat 5 and the barrel 3; the first sealing block 9 and the second sealing block 10 are sealingly sleeved on the screw 4 in sequence; a first through hole 11 is provided on the connecting plate 8 coaxially with the screw 4; an annular flange 12 is provided on the circumferential side of one end of the first sealing block 9 close to the barrel 3, and the other end is penetrated into the first through hole 11; wherein, the first sealing block 9 is clearance-matched with the connecting plate 8, that is, the annular flange 12 is clearance-matched with the connecting plate 8, and the first sealing block 9 is clearance-matched with the first through hole 11; a first groove 13 is concavely provided on the side of the connecting plate 8 facing away from the barrel 3, and the first groove 13 is coaxially arranged with the first through hole 11; the second sealing The block 10 is located in the first groove 13, and the second sealing block 10 is loosely matched with the first groove 13; a plurality of first flow channel holes 14 are provided on the connecting plate 8 at axial intervals around the first through hole 11, and the first flow channel holes 14 are connected to the discharge end of the barrel 3; a plurality of second flow channel holes 15 are provided on the bearing seat 5 at axial intervals, and the plurality of second flow channel holes 15 are connected to the plurality of first flow channel holes 14 in a one-to-one correspondence; a discharge port 16 is provided at one end of the bearing seat 5 away from the connecting plate 8, and the plurality of second flow channel holes 15 are all connected to the discharge port 16; wherein, an annular groove 17 is recessed on the inner side wall of the first through hole 11 around its axial direction, and the first sealing block 9, the annular groove 17 and the second sealing block 10 form an S-shaped gap flow channel in the connecting plate 8.

[0061] It should be noted that the diameter of the annular flange 12 is greater than the diameter of the first through hole 11 .

[0062] The labyrinth effect refers to the function that when a fluid passes through an "S-shaped labyrinth", resistance is generated and its flow rate is reduced.

[0063] In this embodiment, a connecting plate 8 is arranged between the bearing seat 5 and the barrel 3, and the screw 4 passes through the connecting plate 8 through the first through hole 11 and is connected to the self-aligning bearing 6 in the bearing seat 5.

When the slurry passes through the S-shaped gap flow channel, a maze effect will be formed, thereby achieving the purpose of leakage prevention and improving the sealing effect. In addition, after the slurry flows out from the inner cavity of the barrel 3, it passes through the first flow channel hole 14 and the second flow channel hole 15 and then flows into the discharge port 16 for discharge. The discharge is carried out in the form of the first flow channel hole 14 and the second flow channel hole 15, so that a certain pressure is always maintained in the barrel 3, which is convenient for slurry extrusion.

[0064] Based on the above implementation, in a specific implementation, as Figure 6 , Figure 7 and Fig. 9 As shown, a second groove 18 is recessed on the side of the connecting plate 8 facing away from the barrel 3. The diameter of the second groove 18 is larger than the diameter of the first groove 13. The second groove 18 is coaxially arranged with the screw 4. A pan-seal 19 is arranged in the second groove 18. The sealing sleeve of the pan-seal 19 is arranged on the screw 4 and has an interference fit with the second groove 18.

[0066] Specifically, the connecting plate 8 is flange-connected to the barrel 3 to improve the connection strength and sealing performance.

[0067] Based on the above implementation, in a specific implementation, as Figures 1 to 5 As shown, the barrel 3 includes a first barrel body 301 and a second barrel body 302, and the first barrel body 301 and the second barrel body 302 are coaxially detachably connected.

[0068] In this embodiment, the barrel 3 is in the form of a split arrangement connected by a first barrel body 301 and a second barrel body 302, which is convenient for installation, maintenance and transportation after disassembly.

[0069] Specifically, the first cylinder 301 and the second cylinder 302 are connected by flanges to improve connection strength and sealing performance.

[0070] Based on the above implementation, in a specific implementation, as Figures 1 to 5 As shown, an exhaust port 20 is provided at the top of the barrel 3, and the exhaust port 20 is suitable for connecting to an external vacuum device.

[0071] In this embodiment, since the exhaust port 20 is located at the top of the barrel 3, the bubbles in the slurry can easily rise to the top of the barrel 3. The exhaust port 20 can be connected to an external vacuum device. The slurry in the barrel 3 can be extracted by the external vacuum device to discharge the bubbles, which has a degassing function.

[0072] On the basis of the above embodiment, in a specific embodiment, the feed end of the barrel 3 is connected to a feed port 21 .

[0073] In this embodiment, the slurry is conveniently fed into the barrel 3 for transmission through the feed port 21 .

[0074] On the basis of the above-mentioned embodiment, in a specific embodiment, the temperature control assembly includes a plurality of heating elements 22 ; the plurality of heating elements 22 are all sleeved on the barrel 3 , and the plurality of heating elements 22 are evenly arranged along the axial direction of the barrel 3 .

[0076] Specifically, the heating element 22 is cylindrical, and heating wires for heating are evenly arranged inside the heating element 22 .

[0078] In this embodiment, a temperature sensor is installed on the sensor interface 23 for real-time detection of the slurry temperature in the barrel 3 so as to timely monitor the slurry temperature and adjust it in conjunction with the heating element 22, so that the operator can adjust the pulping process in time and ensure that the entire slurry production is more accurate.

[0080] In this embodiment, by arranging a cooling pipeline on the peripheral side of the barrel 3 , when the slurry in the barrel 3 needs to be cooled, a cooling medium can be introduced into the cooling pipeline to adjust the temperature of the slurry in the barrel 3 .

[0081] Based on the above implementation, in a specific implementation, the cooling pipeline is a copper tube.

[0082] In this embodiment, the cooling pipeline is preferably a copper tube, which has good thermal conductivity and thus improves the cooling efficiency.

[0083] Based on the above implementation, in a specific implementation, as Figure 5 , Figure 8 and Fig. 9 As shown, at least one group of stirring components is provided on the barrel 3 around its axial direction, and the stirring components include a plurality of pins 25 arranged at intervals along the axial direction of the barrel 3; one end of the pin 25 is connected to the barrel 3, and the other end extends into the inner cavity of the barrel 3 and is suspended; a plurality of stirring blocks 26 are provided on the screw 4 corresponding to the stirring components, and the stirring blocks 26 and the free ends of the pins 25 are staggered in the rotation direction of the screw 4, and the stirring blocks 26 are suitable for rotating with the rotation of the screw 4 and cooperating with the pins 25 to stir the slurry.

[0084] It should be noted that the portion of the circumference of the screw 4 corresponding to the stirring assembly is not provided with a spiral structure to avoid interference with the latch 25 and affect the rotation.

[0085] In this embodiment, when the screw 4 rotates in the barrel 3, the screw 4 drives the stirring block 26 to rotate at the same time. When the stirring block 26 rotates, it cooperates with the free end of the pin 25 to stir and scatter the passing slurry, thereby improving the uniformity of the slurry.

[0086] Based on the above implementation, in a specific implementation, as Figure 2 As shown, a plurality of mounting holes 27 for mounting the latch pins 25 are provided on the circumferential side of the barrel 3 , and the latch pins 25 are detachably connected to the mounting holes 27 .

[0087] In this embodiment, by providing a mounting hole 27 on the circumferential side of the barrel 3, the latch 25 can be connected to the mounting hole 27, that is, the latch 25 extends from the mounting hole 27 into the inner cavity of the barrel 3 and is connected to the mounting hole 27, which facilitates the installation and removal of the latch 25 for maintenance.

[0088] Specifically, the mounting hole 27 is threadedly connected to the latch pin 25 .

[0089] Specifically, Figure 4 and Figure 5As shown, the drive assembly 2 includes a drive motor 201 and a transmission member 202 arranged on the frame 1, the barrel 3 is flange-connected to the transmission member 202, the screw 4 is rotatably connected to the transmission member 202 through a support bearing, and the output end of the transmission member 202 is drivingly connected to the screw 4; the output end of the drive motor 201 is drivingly connected to the input and output ends of the transmission member 202, and is suitable for driving the screw 4 to rotate through the transmission member 202. The drive motor 201 can change the output speed and torque through the transmission member 202 to improve the working performance of the screw 4, and at the same time, the support bearing and the bearing assembly cooperate at both ends of the screw 4 to support it, improve the support strength, and ensure the stability of the screw 4 during rotation.

[0090] The working principle of the novel single-screw extruder provided in the present embodiment is as follows: when it is necessary to convey the slurry, the driving motor 201 drives the screw 4 to rotate in the barrel 3 through the transmission member 202, and the slurry enters from the feed port 21 on the feed end of the barrel 3. Under the rotation cooperation of the screw 4 and the inner cavity of the barrel 3, the slurry is extruded to the discharge end and conveyed out. When the slurry passes through the stirring assembly, the slurry is stirred and scattered under the cooperation of the latch 25 and the stirring block 26 to improve the uniformity of the slurry. Then the slurry is extruded to the discharge end of the barrel 3, and then the slurry passes from the discharge end through the first flow channel hole 14 and the second flow channel hole 15 of the connecting plate 8 and flows into the discharge port 16 for discharge. At the same time, a part of the slurry flows into the first sealing block 9, the annular groove 17 and the second sealing block 10 forms an S-shaped gap flow channel in the connecting plate 8 and plays a role in preventing leakage, thereby completing the extrusion and transportation of the slurry. In addition, during the slurry transportation process, the temperature of the slurry in the barrel 3 can be detected in real time by the temperature sensor, and the temperature can be adjusted by the heating element 22 and the cooling pipeline, so that the operator can adjust the slurry making process in time, ensure that the entire slurry production is more accurate, and improve the production quality; the bearing assembly and the drive assembly 2 are used to support the two ends of the screw 4, improve the support strength of the screw 4 and the stability during the rotation of the driving screw 4, prevent the screw 4 from deflecting during the working process, reduce the friction between the screw 4 and the barrel 3, and do not need to rotate at a low speed first and then at a high speed during the rotation of the screw 4, thereby improving the working efficiency and service life. The existing single screw 4 extruder solves the technical problems that the screw 4 of the existing single screw 4 extruder only relies on the bearing of the transmission mechanism part to bear the radial force and axial force during the operation, the screw 4 is prone to deflection during the operation, resulting in increased friction between the screw 4 and the inner wall of the barrel 3, and in order to reduce friction, it is necessary to operate at a low speed after starting to transport the slurry before it can operate at a high speed, which is low in efficiency and poor in stability.

[0091] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
