Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and more specifically, to an extrusion mechanism for a high-power extruder. Background Technology

[0002] Extruders were developed based on the clay mixing machines widely used in the processing of original silicate products, such as daily-use ceramic products and industrial ceramic products. They are widely used in the molding and manufacturing of various special-shaped ceramic blanks such as wall and floor tiles, roof tiles, dry-hanging terracotta panels, and kiln rollers, as well as catalyst products for desulfurization, denitrification, and decarbonization.

[0003] Currently, existing extruders mainly work by feeding raw materials into the upper feed port. Through the action of stirring blades and mixing extrusion screws installed in the feed box and the front mud box, the raw materials enter the upper part of the vacuum chamber through the screen plate installed in the front mud box and the vacuum chamber. The mud strips extruded from the screen plate holes are cut into small mud flakes by the blades installed in front of the screen plate and fall into the lower part of the vacuum chamber. At the same time, the mud flakes are vacuumed, and the gas contained inside the mud flakes is discharged outside the vacuum chamber. In the lower part of the vacuum chamber and the mud discharge cylinder connected to the vacuum chamber, there are extrusion screws installed inside. The mud material falling into the lower part of the vacuum chamber is conveyed and extruded by the extrusion screws. Finally, it is formed into the desired product through the nozzle and the extrusion molding die.

[0004] However, during the extruder's operation, due to the resistance generated by the extrusion die, some of the mud will move in the opposite direction along the gap between the mud discharge cylinder and the extrusion screw, resulting in mud backflow. The greater the resistance of the extrusion die, the more mud backflows, thus limiting the increase of the extruder's extrusion pressure. Utility Model Content

[0005] To address the technical problem of reduced extrusion pressure caused by sludge recirculation, this utility model provides the following technical solution:

[0006] A high-power extruder extrusion mechanism includes a base, a support seat fixedly connected to one end of the top of the base, a mud discharge cylinder fixedly connected to the top of the support seat, a feed hopper communicating with the inside of the mud discharge cylinder fixedly connected to one end of the top of the mud discharge cylinder, a first spiral shaft rotatably connected to the inside of the mud discharge cylinder, a drive mechanism for driving the first spiral shaft to rotate at one end of the mud discharge cylinder, and a return mechanism for guiding the mud returned by the mud discharge cylinder back into the inside of the mud discharge cylinder by cooperating with the activation of the drive mechanism at the feed end of the mud discharge cylinder.

[0007] As a preferred embodiment of this utility model, the reflux mechanism includes a cylinder body, which is fixedly connected to the top of the base. A second spiral shaft is rotatably connected to the inner side of the cylinder body. A discharge pipe is fixedly connected to one end of the top of the cylinder body. The top end of the discharge pipe is connected to the inside of the mud discharge cylinder, and the bottom end of the discharge pipe is connected to the inside of the cylinder body.

[0008] As a preferred embodiment of this utility model, the reflux mechanism further includes a reflux pipe fixedly connected to the other end of the top of the cylinder. The top end of the reflux pipe is connected to the inside of the mud discharge cylinder, and the bottom end of the reflux pipe is connected to the inside of the cylinder. The reflux pipe is provided with a stop device for restricting the introduction of mud material from the inside of the mud discharge cylinder into the inside of the cylinder.

[0009] As a preferred embodiment of this utility model, the driving mechanism includes a bracket, which is fixedly connected to one end of the base. A motor is fixedly installed on the top of the bracket, and the output shaft of the motor is fixedly connected to a first spiral shaft.

[0010] As a preferred embodiment of the present invention, the driving mechanism further includes a first pulley, which is fixedly connected to one end of a first spiral shaft, and a second pulley is fixedly connected to one end of the second spiral shaft. The second pulley and the second pulley are connected by a belt drive.

[0011] In a preferred embodiment of this utility model, the spiral directions of the spiral blades of the first spiral shaft and the second spiral shaft are the same, and the length of the first spiral shaft is greater than the length of the second spiral shaft.

[0012] As a preferred embodiment of this utility model, the backstop component includes a guide sleeve, which is fixedly connected to the return pipe. A plurality of mounting seats are fixedly connected to the inner side of the guide sleeve. The plurality of mounting seats are equidistantly distributed around the inner wall of the guide sleeve and spliced ​​into a circular structure. An elastic sheet is fixedly connected to the top of each of the mounting seats. The plurality of elastic sheets can be spliced ​​into a complete circular structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The mud is fed into the mud discharge cylinder through the feed hopper, and then the first screw shaft is driven to rotate by the drive mechanism. The first screw shaft contacts the mud from the outlet end of the mud discharge cylinder. The mud that flows back from the feed end of the mud discharge cylinder will be reintroduced into the mud discharge cylinder through the return mechanism. This can increase the extrusion pressure of the mud at the outlet end of the mud discharge cylinder and effectively avoid the problem of reduced extrusion pressure due to mud return.

[0015] 2. When the mud is introduced into the mud discharge cylinder from the return pipe, all the elastic plates are pushed open to ensure unobstructed flow in the pipeline. After the mud in the discharge cylinder is introduced into the return pipe, all the elastic plates are pressed down and spliced ​​together to form an elastic plate, preventing the mud in the discharge cylinder from being introduced into the cylinder body, thus realizing the one-way discharge function of the mud in the return pipe.

[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] like Figures 1 to 4 As shown, this utility model provides a high-power extruder extrusion mechanism, including a base 1, a support seat 2 fixedly connected to one end of the top of the base 1, a mud discharge cylinder 3 fixedly connected to the top of the support seat 2, a feed hopper 4 fixedly connected to one end of the top of the mud discharge cylinder 3 and communicating with the inside of the mud discharge cylinder 3, a first spiral shaft 5 rotatably connected to the inside of the mud discharge cylinder 3, a drive mechanism 6 for driving the first spiral shaft 5 to rotate at one end of the mud discharge cylinder 3, and a return mechanism 7 for re-introducing the mud material returned by the mud discharge cylinder 3 into the inside of the mud discharge cylinder 3 by cooperating with the start of the drive mechanism 6.

[0023] The mud is fed into the mud discharge cylinder 3 through the feed hopper 4, and then the first spiral shaft 5 is driven to rotate by the drive mechanism 6. The first spiral shaft 5 contacts the mud from the outlet end of the mud discharge cylinder 3. The mud that flows back from the feed end of the mud discharge cylinder 3 is reintroduced into the mud discharge cylinder 3 through the return mechanism 7. This increases the extrusion pressure of the mud at the outlet end of the mud discharge cylinder 3 and effectively avoids the problem of reduced extrusion pressure due to mud return.

[0024] The reflux mechanism 7 includes a cylinder 71, which is fixedly connected to the top of the base 1. A second spiral shaft 72 is rotatably connected to the inner side of the cylinder 71. A discharge pipe 73 is fixedly connected to one end of the top of the cylinder 71. The top end of the discharge pipe 73 is connected to the inside of the mud discharge cylinder 3, and the bottom end of the discharge pipe 73 is connected to the inside of the cylinder 71. A return pipe 74 is fixedly connected to the other end of the top of the cylinder 71. The top end of the return pipe 74 is connected to the inside of the mud discharge cylinder 3, and the bottom end of the return pipe 74 is connected to the inside of the cylinder 71. A stopper 75 is provided on the return pipe 74 to restrict the mud from entering the cylinder 71.

[0025] The mud material flowing back from the inlet end of the mud discharge cylinder 3 can be guided into the cylinder body 71 through the discharge pipe 73. Then, the rotation of the second spiral shaft 72 causes the mud material entering the cylinder body 71 to be reintroduced into the mud discharge cylinder 3 through the return pipe 74. This can greatly increase the extrusion pressure of the mud material at the outlet end of the mud discharge cylinder 3.

[0026] The drive mechanism 6 includes a bracket 61, which is fixedly connected to one end of the base 1. A motor 62 is fixedly mounted on the top of the bracket 61. The output shaft of the motor 62 is fixedly connected to a first spiral shaft 5. A first pulley 63 is fixedly connected to one end of the first spiral shaft 5, and a second pulley 64 is fixedly connected to one end of a second spiral shaft 72. The second pulleys 64 are connected by a belt drive. The spiral directions of the spiral blades of the first spiral shaft 5 and the second spiral shaft 72 are the same, and the length of the first spiral shaft 5 is greater than the length of the second spiral shaft 72. By starting the motor 62, the first spiral shaft 5 is driven to rotate, causing it to squeeze out the mud from inside the mud discharge cylinder 3. Simultaneously, the first pulley 63 rotates synchronously with the first spiral shaft 5, causing the second pulley 64 to rotate. This causes the second spiral shaft 72 to rotate synchronously, allowing the mud that has entered the cylinder 71 to be reintroduced into the mud discharge cylinder 3 through the return pipe 74.

[0027] The backstop 75 includes a guide sleeve 751, which is fixedly connected to the return pipe 74. Several mounting seats 752 are fixedly connected to the inner side of the guide sleeve 751. These mounting seats 752 are equidistantly distributed around the inner wall of the guide sleeve 751 and are assembled into a circular structure. Each mounting seat 752 has an elastic piece 753 fixedly connected to its top. These elastic pieces 753 can be assembled into a complete circular structure. When the mud is introduced into the mud cylinder 3 from the return pipe 74, all the elastic pieces 753 are pushed open to ensure unobstructed flow. After the mud from the mud cylinder 3 is introduced into the return pipe 74, all the elastic pieces 753 are pressed down and assembled into an elastic piece 753, preventing the mud in the mud cylinder 3 from entering the cylinder body 71, thus achieving a one-way mud discharge function.

[0028] Working principle: The mud is fed into the mud discharge cylinder 3 through the feed hopper 4. Then, the motor 62 is started to drive the first spiral shaft 5 to rotate, so that the first spiral shaft 5 squeezes out the mud inside the mud discharge cylinder 3. The mud flowing back from the inlet end of the mud discharge cylinder 3 can be guided into the cylinder body 71 through the discharge pipe 73. At the same time, the first pulley 63 rotates synchronously with the first spiral shaft 5, so that the second pulley 64 rotates, which makes the second spiral shaft 72 rotate synchronously. This allows the mud that has entered the cylinder body 71 to be reintroduced into the mud discharge cylinder 3 through the return pipe 74. This can greatly increase the extrusion pressure of the mud at the outlet end of the mud discharge cylinder 3.
