Description

Technical Field

[0001] This utility model relates to pulverizing equipment, and more particularly to a pulverizing device that can improve pulverizing effect. Background Technology

[0002] Currently, the crushing structure of crushers uses multiple cutter discs arranged on a rotating roller, with crushing blades bolted to each disc. The rotating roller drives the cutter discs to rotate, and the crushing blades on the rotating discs crush the material entering the crushing chamber. Furthermore, the crushing blades in this structure are mostly straight blades mounted on the outer periphery of the cutter discs. This structure is beneficial for crushing materials on the outer edge of the discs, but the crushing effect on materials between the two discs is poor, resulting in poor overall crushing effect and low crushing efficiency. Moreover, the crushing blades wear out quickly during use, leading to frequent blade replacements and increased wear and tear. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pulverizing device that can improve the overall pulverizing effect of materials and reduce the frequency of pulverizing blade replacement.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a pulverizing device that can improve the pulverizing effect, including a cutter disc, wherein a plurality of pulverizing blades are evenly distributed on both sides of the outer periphery of the cutter disc, each pulverizing blade includes a vertical blade body, a connecting part is provided at the inner end of the vertical blade body, a fixed connecting device is provided between the connecting part and the cutter disc, and a horizontal blade body is provided at the outer end of the pulverizing blade extending away from the cutter disc, wherein pulverizing blades are provided on the front and rear sides of the vertical blade body and the horizontal blade body respectively.

[0005] As a preferred technical solution, the fixed connection device includes fixed grooves on both sides of the outer peripheral surface of the cutter head for inserting the connecting part, the connecting part being inserted into the fixed groove, and a fixed bolt threadedly connected to the cutter head passing through the connecting part.

[0006] As a preferred technical solution, the connecting part is provided with a groove to accommodate the head end of the fixing bolt, and the outer surface of the connecting part is not higher than the outer peripheral surface of the cutter head.

[0007] As a preferred technical solution, the fixed connection device includes fixed grooves on the outer periphery of both sides of the cutter head for inserting the connecting part. The connecting part is inserted into the fixed groove, and a fixing bolt is provided through the connecting part and the cutter head. A fixing nut is threaded on the fixing bolt to fix the connecting part and the cutter head together.

[0008] As a preferred technical solution, the outer surface of the connecting part is provided with a groove for accommodating the head of the fixing nut and the fixing bolt, and the outer surface of the connecting part is not higher than the side surface of the cutter head.

[0009] As a preferred technical solution, the crushing blades located on both sides of the blade disc are arranged symmetrically or alternately.

[0010] The pulverizing device, which improves the pulverizing effect by adopting the above-mentioned technical solution, includes a cutter disc. Several pulverizing blades are evenly distributed on both sides of the outer periphery of the cutter disc. Each pulverizing blade includes a vertical blade body with a connecting portion at its inner end. A fixing connection device is provided between the connecting portion and the cutter disc. A horizontal blade body extends from the outer end of each pulverizing blade away from the cutter disc. Pulverizing blades are respectively provided on the front and rear sides of the vertical and horizontal blade bodies. In this invention, the pulverizing blades on both sides of the outer periphery of the cutter disc employ vertical blade bodies and extended horizontal blade bodies. The vertical blade bodies pulverize the material on the outer periphery of the cutter disc, while the extended horizontal blade bodies pulverize the material between the two cutter discs, resulting in a better pulverizing effect, improved overall pulverizing efficiency, and higher material pulverizing efficiency. Furthermore, the vertical and horizontal blades are equipped with crushing blades on their front and rear sides respectively. This way, when the crushing blades on the front side of the vertical and horizontal blades wear out, only the corresponding two crushing blades on both sides of the blade disc need to be swapped so that the crushing blades on the rear side of the vertical and horizontal blades are installed on the blade disc with the rear side facing forward. There is no need to replace the crushing blades with new ones. The frequency of crushing blade replacement is low, which reduces the wear and tear of the crushing blades and reduces energy consumption. Attached Figure Description

[0018] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0019] like Figure 1 and 2 As shown, a pulverizing device that improves pulverizing effect includes a cutter disc 1. Several pulverizing blades 2 are evenly distributed on both sides of the outer periphery of the cutter disc 1. Each pulverizing blade 2 includes a vertical blade body 4, with a connecting part 3 at its inner end. A fixed connection device is provided between the connecting part 3 and the cutter disc 1. A horizontal blade body 5 extends from the outer end of each pulverizing blade 2 away from the cutter disc 1. Pulverizing blades 6 are respectively provided on the front and rear sides of the vertical blade body 4 and the horizontal blade body 5. During operation, the pulverizing blades 6 on the front side of the vertical blade body 4 pulverize the material on the outer periphery of the cutter disc 1, while the pulverizing blades 6 on the front side of the extended horizontal blade body 5 pulverize the material between the two cutter discs 1. Since the pulverizing blades 6 are provided on the front and rear sides of the vertical blade body 4 and the horizontal blade body 5, after wear, only the corresponding two pulverizing blades 2 on each side of the cutter disc 1 need to be swapped; new pulverizing blades 2 do not need to be replaced.

[0020] like Figure 3 The diagram shows a first embodiment of the fixed connection device. The fixed connection device includes fixed grooves 7 on both sides of the outer circumferential surface of the cutter disc 1, into which a connecting part 3 is inserted. The connecting part 3 is inserted into the fixed groove 7, and a fixing bolt 8, threadedly connected to the cutter disc 1, passes through the connecting part 3. The outer surface of the connecting part 3 is not higher than the outer circumferential surface of the cutter disc 1. The fixed groove 7, located on the outer circumferential surface of the cutter disc 1, serves to constrain and position the crushing blade 2, and cooperates with the fixing bolt 8 to firmly fix the crushing blade 2 to the outer circumferential surface of the cutter disc 1. The fact that the outer surface of the connecting part 3 is not higher than the outer circumferential surface of the cutter disc 1 reduces the contact between the connecting part 3 and the material, thus reducing wear. Simultaneously, the connecting part 3 has a groove 9 to accommodate the head of the fixing bolt 8, further reducing the contact between the head of the fixing bolt 8 and the material, preventing severe wear of the head of the fixing bolt 8 that would lead to inconvenient disassembly.

[0021] like Figure 4 and 5As shown, this is a second embodiment of the fixed connection device. The fixed connection device includes fixing grooves 7 on the outer periphery of both sides of the cutter disc 1, into which the connecting part 3 is inserted. The connecting part 3 is inserted into the fixing groove 7, and a fixing bolt 8 is provided passing through the connecting part 3 and the cutter disc 1. A fixing nut 10 is threaded onto the fixing bolt 8 to fix the connecting part 3 and the cutter disc 1 together. In this way, the fixing groove 7 is located on the outer periphery of both sides of the cutter disc 1, which plays a role in constraining and positioning the crushing blade 2. The fixing bolt 8 and the fixing nut 10 cooperate to firmly fix the crushing blade 2 to the side of the cutter disc 1. The outer surface of the connecting part 3 is provided with a groove 9 to accommodate the head of the fixing nut 10 and the head of the fixing bolt 8, which reduces the contact between the head of the fixing nut 10 and the head of the fixing bolt 8 and the material, and avoids severe wear of the head of the fixing bolt 8 and the fixing nut 10, which would make disassembly inconvenient. In addition, the outer surface of the connecting part 3 is not higher than the side surface of the cutter disc 1, which reduces the contact between the connecting part 3 and the material and reduces wear.

[0022] The fixing connection device of this utility model adopts the above two embodiments, both of which improve the installation firmness of the crushing blade 2, and at the same time reduce the wear on the connecting part 3 of the crushing blade 2 and the connecting components such as the fixing bolt 8 and the fixing nut 10; while as Figure 2 The pulverizer 2 shown in the diagram uses an existing connection method with the cutter disc 1. This involves directly fixing the pulverizer 2 to the outer periphery of both sides of the cutter disc 1 with bolts. The connecting part 3 and connecting components of the pulverizer 2 protrude from both sides of the cutter disc 1, resulting in significant wear from the material. Therefore, compared to the existing connection method where the connecting part 3 and connecting components of the pulverizer 2 protrude from both sides of the cutter disc 1, the fixing connection device used in this invention for installing the pulverizer 2 on the cutter disc 1 reduces wear on the connecting part 3 and connecting components of the pulverizer 2, improves the stability of the pulverizer 2 installation, and facilitates the assembly and disassembly of the pulverizer 2.

[0023] As shown in Figure 3, the connecting part 3 can be T-shaped, and the fixing groove 7 is shaped to match the connecting part 3, making the connecting part 3 and the fixing groove 7 regular in shape, which facilitates the fixing groove 7 to be slotted on the cutter disc 1 and to constrain and support the connecting part 3. The crushing blades 2 located on both sides of the cutter disc 1 are symmetrically arranged, or they can be staggered. The symmetrical arrangement of the crushing blades on both sides of the cutter disc 1 improves the uniformity of the force on the cutter disc 1 and facilitates the disassembly, assembly, and replacement of the crushing blades 2 after damage. Of course, the staggered arrangement of the crushing blades on both sides of the cutter disc 1 is also acceptable.

[0024] like Figure 1As shown, in use, multiple cutter discs 1 are fixedly mounted on the rotating roller inside the crushing chamber of the crusher through shaft holes 11. The cutter discs 1 are arranged at intervals on the rotating roller. The crusher's power system drives the rotating roller to rotate, which in turn drives the cutter discs 1 to rotate. The crushing blades 2 on the rotating cutter discs 1 crush the material entering the crushing chamber. Specifically, the vertical blades 4 crush the material on the outer periphery of the cutter discs 1, and the horizontal blades 5 crush the material between the two cutter discs 1. When the crushing blades 6 of the vertical blades 4 and the horizontal blades 5 become worn, it is only necessary to remove the fixing bolts 8 and swap the corresponding two crushing blades 2 on both sides of the cutter disc 1, so that the rear crushing blades 6 of the vertical blades 4 and the horizontal blades 5 are installed on the cutter disc 1 with the rear facing forward.
