Abstract
Description
Technical Field
[0001] This utility model relates to the field of material extrusion equipment technology, specifically to an extruder pressing device. Background Technology
[0002] The extruder's pressing device is a key component used for dewatering and shaping materials such as sludge, clay, and ceramic blanks. Its core function is to remove moisture from the material through mechanical extrusion, while forming a specific shape (such as strips or blocks).
[0003] Existing extruder sludge pressing devices feed wet sludge into the equipment through the inlet, and are propelled forward by a screw conveyor shaft. Under the rotation of the screw shaft, the sludge is gradually compressed. The screw pitch gradually decreases or the shaft diameter gradually increases, which continuously increases the spatial pressure on the sludge during the conveying process, resulting in extrusion and dewatering. The dewatered sludge cake is then discharged from the outlet. However, because the sludge cake has a certain degree of stickiness, residue will adhere to the inner wall of the outlet during the discharge process, causing blockage of the outlet. Utility Model Content
[0004] The purpose of this invention is to provide an extruder pressing device to solve the problem mentioned in the background art where residue adheres to the inner wall of the discharge port during the discharge of the mud cake, causing blockage of the discharge port.

The rotating shaft is fixedly connected to the end of the output shaft of the motor. The curved drive block is fixedly connected to the end of the rotating shaft. The slide groove is formed on the surface of the frame. The slider is slidably connected to the inside of the frame. The slide rod is fixedly connected to the side wall of the slider near the discharge port, and the slide rod abuts against the curved drive block. One end of the spring is fixedly connected to the outer wall of the slide rod. The bracket is fixedly connected to the top of the frame. The other end of the spring is fixedly connected to the end of the bracket. The impact rod is fixedly installed on the side of the slider near the discharge port, and the end of the impact rod away from the slider extends out of the frame.
[0008] Preferably, the slide rod is also fixedly connected to the side wall of the slider away from the discharge port, and the spring is also connected between the slide rod and the end of the bracket.
[0009] Preferably, the slide bars and springs located on both sides of the slider are symmetrically arranged.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides an extruder pressing device. The input end of the device body 1 is fixedly connected to a feed port 2, and the output end of the device body 1 is fixedly connected to a discharge port 3. A blocking mechanism 4 is provided on one side of the device body 1 for reciprocating impact on the side wall of the discharge port 3.
[0023] The anti-blocking mechanism 4 includes a frame 401, a motor 402, a striker 403, a rotating shaft 404, a curved drive block 405, a slide groove 406, a slide rod 407, a spring 408, a bracket 409, and a slider 4010.
[0024] The frame 401 is fixedly connected to the device body 1 on the side near the discharge port 3. The motor 402 is fixedly installed on the side wall of the device body 1 corresponding to the frame 401. The rotating shaft 404 is fixedly connected to the output shaft end of the motor 402. The curved drive block 405 is fixedly connected to the end of the rotating shaft 404. The slide groove 406 is formed on the surface of the frame 401. The slider 4010 is slidably connected to the inside of the frame 401. The slide rod 407 is fixedly connected to the slider. On the side wall of the slider 4010 near the discharge port 3, the slide rod 407 abuts against the curved drive block 405. One end of the spring 408 is fixedly connected to the outer wall of the slide rod 407. The bracket 409 is fixedly connected to the top of the frame 401. The other end of the spring 408 is fixedly connected to the end of the bracket 409. The impact rod 403 is fixedly installed on the side of the slider 4010 near the discharge port 3, and the end of the impact rod 403 away from the slider 4010 extends out of the frame 401.
[0025] In this embodiment: wet sludge is fed into the device body 1 through the feed inlet 2 for processing, and the dehydrated sludge cake is discharged to the outside through the discharge outlet 3.
[0026] In one or more embodiments of this utility model, a sliding rod 407 is also fixedly connected to the side wall of the slider 4010 away from the discharge port 3, and a spring 408 is also connected between the sliding rod 407 and the end of the bracket 409. By also providing a sliding rod 407 and a spring 408 on the side of the slider 4010 away from the discharge port 3, the stability of the slider 4010 during the sliding process can be ensured.
[0027] Preferably, in one or more embodiments of the present invention, the slide rods 407 and springs 408 located on both sides of the slider 4010 are symmetrically arranged, which can ensure the sliding stability of the slider 4010 while making the force on the slider 4010 more balanced.
[0028] Please refer to this carefully. Figure 3 The output shaft of the energized motor 402 drives the rotating shaft 404 to rotate, and the rotating shaft 404 drives the curved drive block 405 to rotate. In this embodiment, the rotating curved drive block 405 drives the slide rod 407 to move under the action of the curved surface, and the slide rod 407 drives the slider 4010 to reciprocate within the inner cavity of the frame 401 along the inner wall trajectory of the slide groove 406.
[0029] In this embodiment: when the slider 4010 moves away from the bracket 409, it stretches the spring 408. Then, the spring 408 in the reset state moves towards the bracket 409. The spring 408 in the extendable state assists the slider 4010 in moving.
[0030] In this embodiment: Since the curved drive block 405 is in contact with the surface of the slide bar 407, the curved drive block 405 in the rotating state drives the slide bar 407 to move under the action of the curved surface. Then the slider 4010 in the moving state drives the impact bar 403 to reciprocate, and then the impact bar 403 in the moving state impacts the surface of the discharge port 3 in the direction closer to the discharge port 3.
[0031] In this embodiment of the present invention, the curved drive block 405 is rotatably connected to the side wall of the frame 401 via a rotating shaft 404. In this way, the frame 401 can provide stable support for the curved drive block 405 and prevent it from shifting during the compression process with the slide rod 407.
[0032] Optionally, the frame 401 is provided with a limiting groove that matches the slider 4010. When the slider 4010 moves to the end of its stroke away from the discharge port 3, a gap is left between the end of the impact rod 403 away from the slider 4010 and the corresponding end wall of the frame 401. The limiting groove that matches the slider 4010 can limit the movement trajectory of the slider 4010. At the same time, when the slider 4010 moves to the end of its stroke away from the discharge port 3, a gap is left between the end of the impact rod 403 away from the slider 4010 and the corresponding end wall of the frame 401. This can prevent the end of the impact rod 403 from colliding with the corresponding end wall of the frame 401 during the movement of the slider 401, thus affecting its working stability.
[0033] Please refer to this carefully. Figure 3 The slide rod 407 is disposed through the slide groove 406, and the size of the slide rod 407 matches the size of the slide groove 406, so that the slide rod 407 can play a limiting role during the movement.
[0034] Optionally, an impact head may be detachably installed at the end of the impact rod 403 away from the slider 4010, so that the impact head can be replaced after wear.
[0035] During operation, wet sludge is first fed into the device body 1 through the feed inlet 2 for processing. The dewatered sludge cake is then discharged to the outside through the discharge outlet 3. Next, the motor 402 is powered on and started, causing the output shaft of the running motor 402 to drive the rotating shaft 404 to rotate. The rotating shaft 404 then drives the curved drive block 405 to rotate. Since the curved drive block 405 is in contact with the surface of the slide rod 407, the rotating curved drive block 405, under the action of the curved surface, drives the slide rod 407 to move, causing the slide rod 407 to move along the inner wall trajectory of the slide groove 406, thus moving the slider 407. 10 reciprocates within the cavity of frame 401. The slider 4010, which moves away from support 409, stretches spring 408. The spring 408, in its reset state, moves closer to support 409. The retractable spring 408 assists slider 4010 in moving. The moving slider 4010 then drives impact rod 403 to reciprocate. The impact rod 403, which moves closer to discharge port 3, impacts the surface of discharge port 3. This structure effectively reduces the likelihood of blockage inside discharge port 3.
[0036] It should be noted that when the protruding part of the curved drive block 405 pushes the slide bar 407, the impact bar 403 rushes towards the discharge port 3 and impacts its outer wall or internal structure, generating strong vibration and impact force. Sludge is prone to forming "bridge" or "arch" blockage in the discharge port 3. The impact of the impact bar 403 will cause vibration in the inner wall of the discharge port 3, destroying this stable arch structure, making the sludge loose, and thus falling under the action of gravity. The impact force will be transmitted through the inner wall of the discharge port 3 to the sludge layer attached to it, shaking off the adhering sludge. Therefore, in the early stage of blockage, this impact method can indeed play a certain role in clearing and preventing blockage.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
