Description

Technical Field

[0001] This utility model relates to the field of granulation and extrusion equipment technology, specifically to a granular refining agent extruder. Background Technology

[0002] Granular refining agent extruders are specialized equipment used to process refining agent raw materials into granular products through an extrusion process. They are widely used in industries such as metallurgy, chemicals, and building materials.

[0003] In the existing technology, some refining agent extruders adopt a design in which the cutter and the screw are directly connected. In this structure, the screw speed is directly related to the cutting frequency of the cutter. During production, the screw speed needs to be frequently adjusted according to factors such as raw material characteristics and extrusion pressure. Once the screw speed changes, the cutting rhythm of the cutter will also change, making it difficult to accurately control the particle size of the refining agent. Utility Model Content

[0004] The purpose of this invention is to provide a granular refining agent extruder to solve the technical problem mentioned in the background art, which is that the design of directly connecting the cutter to the screw makes it difficult to accurately control the size of the refining agent particles being cut.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A granular refining agent extruder includes a mounting plate on which an extruder is fixedly mounted. A granulation mechanism is fixedly mounted inside the extrusion port of the extruder, so that when the refining agent raw material is extruded from the extruder, it can be formed into a columnar body and cut into granules by the granulation mechanism. A box frame is fixedly mounted on the outer surface of the extrusion port of the extruder, which can receive the granules formed by cutting.

[0007] As a further embodiment of this utility model, a closing cover is rotatably installed at one end of the box frame. The closing cover can close the box frame by flipping it over, so that it can form a material guide tube.

[0008] As a further embodiment of this utility model, four sets of cooling fans are fixedly installed on the upper surface of the closed cover. The cooling fans are opposite to the filter holes, which are opened on the upper surface of the closed cover, so that the cooling fans can blow cold air into the box frame through the filter holes.

[0009] As a preferred embodiment of this utility model, the pelletizing mechanism includes an extrusion die, which is fixedly installed inside the barrel outlet of the extruder. A connecting column is fixedly installed at one end of the extrusion die, and a rotating cylinder is rotatably installed on the outer surface of the connecting column. A cross cutter is fixedly installed on the outer surface of the rotating cylinder. The cross cutter contacts one end of the extrusion die through the rotation of the rotating cylinder, so that the rotating cross cutter can cut the extruded columnar body into pellets.

[0010] As a further embodiment of this utility model, a first transmission disc is fixedly installed on the outer surface of the rotating drum, a transmission belt is fitted on the outer surface of the first transmission disc, the other end of the transmission belt is fitted on the outer surface of the second transmission disc, the second transmission disc is fixedly installed on one end of the output shaft of the motor, and the motor is fixedly installed on the upper surface of the box frame.

[0011] As a further embodiment of this utility model, one end of the rotating drum is inserted into the U-shaped tube, so that the first transmission disc and the transmission belt are both surrounded by the U-shaped tube. The U-shaped tube is fixedly installed in the box frame, thereby preventing the cut particles from splashing into the first transmission disc and the transmission belt.

[0012] Compared with the prior art, the beneficial effects of this utility model of a granular refining agent extruder are as follows:

[0013] By pouring the refining agent raw material into the extruder, the extruder heats the raw material and extrudes it through the internal screw. During the extrusion process, the refining agent raw material passes through the granulation mechanism and forms multiple sets of columnar bodies. These columnar bodies are then cut into granules by the granulation mechanism and guided by the box frame. As the cut granules slide within the box frame, the cooling fan on the closed cover continuously blows cold air into the box frame through the filter holes to accelerate the cooling and solidification of the granules, ensuring their shape stability. The independent cutting function can adjust the cutting frequency in real time according to different raw material characteristics and extrusion rates. When the extrusion speed increases, the cutter speed can be increased simultaneously to ensure that the cutting length of each columnar body is consistent and to avoid the problem of mixing "large and small granules".

[0023] See Figure 1-2 As shown in the figure, an embodiment of the present invention provides a granular refining agent extruder, including a mounting plate 1. An extruder 101 is fixedly mounted on the upper surface of the mounting plate 1. A granulation mechanism 2 is fixedly mounted inside the extrusion port of the extruder 101, so that when the refining agent raw material is extruded from the extruder 101, it can be formed into a columnar body and cut into granules by the granulation mechanism 2. A box frame 102 is fixedly mounted on the outer surface of the extrusion port of the extruder 101, which can receive the granules formed by cutting. A closing cover 103 is rotatably mounted on one end of the box frame 102. The closing cover 103 can be closed by flipping to form a guide tube. Four sets of cooling fans 105 are fixedly mounted on the upper surface of the closing cover 103. The cooling fans 105 are opposite to the filter holes 104. The filter holes 104 are opened on the upper surface of the closing cover 103, so that the cooling fans 105 can blow cold air into the box frame 102 through the filter holes 104.

[0024] In use, the refining agent raw material can be poured into the extruder 101, which heats the raw material and extrudes it through the internal screw. During the extrusion process, the raw material passes through the granulation mechanism 2 and forms multiple sets of columnar bodies. The columnar bodies are then cut into granules by the granulation mechanism 2 and received and guided by the box frame 102. As the cut granules slide within the box frame 102, the cooling fan 105 on the closed cover 103 continuously blows cold air into the box frame 102 through the filter holes 104 to accelerate the cooling and solidification of the granules and ensure their shape stability. This independent cutting function can adjust the cutting frequency in real time according to the characteristics of different raw materials and the extrusion rate. When the extrusion speed increases, the cutter speed can be increased simultaneously to ensure that the cutting length of each columnar body is consistent and to avoid the problem of mixing of "large and small granules".

[0025] See Figures 3-4 As shown, the pelletizing mechanism 2 includes an extrusion die 201, which is fixedly installed inside the barrel outlet of the extruder 101. A connecting column 206 is fixedly installed at one end of the extrusion die 201. A rotating drum 203 is rotatably installed on the outer surface of the connecting column 206. A cross cutter 204 is fixedly installed on the outer surface of the rotating drum 203. The cross cutter 204 rotates and contacts one end of the extrusion die 201, thereby enabling the rotating cross cutter 204 to cut the extruded columnar body into pellets. A first transmission disc 205 is fixedly installed on the outer surface of the rotating drum 203. A transmission belt 208 is fitted on the outer surface of the first transmission disc 205. The other end of the transmission belt 208 is fitted on the outer surface of a second transmission disc 207. The second transmission disc 207 is fixedly installed at one end of the output shaft of a motor 202. The motor 202 is fixedly installed on the upper surface of the frame 102. One end of the rotating drum 203 is inserted into the U-shaped tube 106, so that the first transmission disc 205 and the transmission belt 208 are both enclosed by the U-shaped tube 106. The U-shaped tube 106 is fixedly installed in the box frame 102, so as to prevent the cut particles from splashing into the first transmission disc 205 and the transmission belt 208.

[0026] During the extrusion process of the extruder 101, the refining agent raw material is extruded through the screw, passing through the extrusion die 201 fixedly installed inside the barrel. This forms multiple sets of cylindrical bodies of equal size. Simultaneously, the motor 202 can be started, driving the transmission belt 208 via the second transmission disc 207. The transmission belt 208 then drives the first transmission disc 205, causing the drum 203 to rotate on the outer surface of the connecting column 206. This allows the drum 203 to drive the cross cutter 204 fixedly installed on the outer surface to cut the extruded cylindrical bodies into granules. After the cross cutter 204 completes the cutting of the cylindrical bodies, the closed protective structure of the U-shaped tube 106 effectively... To prevent particles from splashing into the transmission belt 208 and the first transmission disc 205, thus avoiding transmission failure or equipment damage caused by foreign objects getting stuck, the failure rate of the transmission system is reduced. The cut particles can fall into the box frame 102 and slide out along its inclined inner wall. During this process, the cooling fan 105 can continuously inject cold air through the filter hole 104 to accelerate the cooling of the particles, so that they have completed preliminary solidification before contacting the inner wall of the box frame 102, reducing the risk of adhesion. In this type, the motor 202 independently controls the speed of the cross cutter 204, decoupled from the screw extrusion speed, allowing it to accurately adjust the cutting frequency according to the characteristics of the raw materials and particle specifications, ensuring that the particle length error meets the process requirements, and the consistency is significantly improved compared with the traditional screw linkage cutting.

[0027] In summary, this extruder allows the motor 202 to independently control the speed of the cross cutter 204, decoupling it from the screw extrusion speed. This enables the motor to precisely adjust the cutting frequency according to the characteristics of the raw materials and particle size, ensuring that the particle length error meets the process requirements. The consistency is significantly improved compared to traditional screw-driven cutting.

[0028] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
