Description

Technical Field

[0001] This utility model relates to the field of cement preparation technology, specifically to a cement preparation dispersion processing device. Background Technology

[0002] Cement is made by grinding and mixing limestone, clay, and iron ore powder in a certain proportion. This mixture is called raw meal. Then it is calcined, usually at a temperature of around 1450 degrees Celsius. The product after calcination is called clinker. Then the clinker and gypsum are ground together and mixed in a certain proportion to make cement. In the process of cement preparation, there is a step that requires dispersing the cement, which requires the use of corresponding dispersion processing equipment.

[0003] A search revealed that patent CN202322123723.8 discloses a cement preparation and dispersion processing device. While this device utilizes an extrusion assembly to disperse materials in conjunction with a guide block, a discharge assembly to move and unload the dispersed material, an opening and closing assembly to open and close the discharge hopper, and a dust suction assembly to remove dust during feeding, it may not achieve the desired dispersion effect when handling large pieces of material. These materials may remain in large lumps during extrusion, leading to blockages in subsequent processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cement preparation and dispersion processing device, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A cement preparation and dispersion processing device includes a machine body, a feeding trough installed on one side of the machine body, a feeding auger installed in the feeding trough, a shell installed on the top of the machine body, a roller cutter rotatably installed inside the machine body, and a discharge hopper installed below the roller cutter on the machine body.

[0007] The machine body is provided with an inner liner on the outside of the roller cutter. The roller cutter is rotatably installed in the inner liner. The inner liner is composed of a top cover and a screen. The roller cutter is provided with a discharge port. The inner and outer surfaces of the roller cutter at the discharge port are respectively equipped with an outer cutter head and an inner cutter head. A feed head is installed at one end of the roller cutter in the machine body. A through hole is opened through the feed head.

[0008] A spring is installed on the feeding auger, a keyway is provided on the feeding auger, a transmission wheel is installed on the feeding auger through the keyway for limiting, and a bearing seat is provided at one end of the feeding auger located outside the feeding trough.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the screen is located below the top cover and directly above the hopper.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The screen is located below the top cover, ensuring that the raw materials, after being broken up by the rotary cutter, pass through the screen before entering the hopper. This design effectively filters out raw materials that meet the particle size requirements, preventing large or substandard materials from directly entering the hopper, thus improving screening efficiency and product quality. The screen is located directly above the hopper, guiding the screened material smoothly into the hopper. This design helps ensure continuous and uniform material flow, preventing accumulation and blockage at the screen or hopper, and improving overall production efficiency.

[0013] Furthermore, the transmission wheel is provided with key teeth, and the transmission wheel slides at the upper limit of the feeding auger through the cooperation of the key teeth and the keyway. The transmission wheel and the bearing seat are both located on the outside of the feeding groove.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The keyed teeth inside the drive wheel engage tightly with the keyways on the feeding auger. This design ensures stable transmission performance when the drive wheel rotates the feeding auger. The interaction between the keyed teeth and keyways not only provides the necessary driving force but also limits the feeding auger's reciprocating motion, preventing deviation or wobbling during operation and ensuring continuous and accurate feeding. The keyed teeth and keyways also increase the connection strength between the drive wheel and the feeding auger, making the entire transmission system more robust and durable. This design helps resist impacts and vibrations during operation, extending the service life of the device.

[0016] Furthermore, the feeding auger is provided with a limiting block, and the spring is installed between the limiting block and the feeding trough by limiting the spring.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The limiting block design provides a stable support point for the spring, ensuring its stability and reliability during installation and use. Simultaneously, the connection between the spring and the feed chute via the limiting block provides elastic support and limits to the feeding auger, preventing excessive deviation or swaying during operation, thus ensuring continuous and accurate feeding. The cooperative design of the limiting block and spring increases the connection strength between the feeding auger and the feed chute, making the entire feeding system more robust and durable. This design helps resist impacts and vibrations during operation, extending the service life of the device. The limiting block design also simplifies spring installation and adjustment. When adjusting the spring preload or replacing the spring, this can be achieved by adjusting the position of the limiting block without the need for complex disassembly and reassembly of the entire feeding system. This design reduces maintenance difficulty and cost, improving the maintenance efficiency of the device.

[0019] Furthermore, the end of the feed auger is located inside the feed head.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The end of the feed auger extends directly into the feed head, ensuring precise feeding of raw materials into the cutter head or other processing devices. This design reduces leakage and waste during transport, improving material utilization. Because the auger end is located inside the feed head, the material transitions more smoothly during transport, reducing increased resistance due to changes in the transport path. This helps improve feeding efficiency, ensuring a continuous and stable supply of raw materials to the next processing stage. Placing the auger end inside the feed head also helps reduce the risk of blockages during transport. As the material enters the feed head, its flow direction is more precisely guided, preventing blockages caused by poor flow.

[0022] Furthermore, the length of the inner liner is adapted to the length of the hob.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] When the length of the liner is matched to the length of the roller cutter, it ensures that the roller cutter and liner work together fully during rotation, reducing friction and wear caused by length mismatch. This design helps protect critical components of the equipment, improving their wear resistance and service life. A properly matched liner length ensures that materials are fully dispersed and crushed under the action of the roller cutter. During rotation, the roller cutter's length matches the liner, allowing for more effective cutting and grinding of materials, thus improving material dispersion and crushing efficiency. Because the liner and roller cutter lengths are matched, equipment vibration and noise caused by length mismatch are reduced. This design helps reduce equipment failure rates and improves equipment stability and reliability.

[0025] Furthermore, the inner cutter head is cone-shaped inside the roller cutter. The inner cutter head breaks up large pieces of raw material, which then enters the upper cover through the discharge port. The upper cover and the outer cutter head work together to further break up the raw material.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The conical inner cutter head design allows the rotary cutter to more effectively break down large pieces of raw material during rotation. The conical structure of the inner cutter head ensures that the material is evenly dispersed under cutting force, preventing accumulation and blockage inside the cutter. The material is first initially broken down by the inner cutter head and then enters the upper cover through the discharge port. Inside the upper cover, the material works in conjunction with the outer cutter head for further breaking down. This design optimizes the breaking down process, allowing the material to undergo multiple cuts and grinding processes, resulting in better dispersion. Due to the cooperation between the inner and outer cutter heads, the equipment's processing capacity is significantly improved. The equipment can more effectively process large, hard raw materials, dispersing them into smaller particles to meet the requirements of subsequent processing.

[0028] This utility model provides a cement preparation, dispersion, and processing device. It has the following beneficial effects:

[0029] The conical design of the inner and outer cutters on the roller cutter effectively breaks down large pieces of raw material. A multi-stage dispersing process (first at the inner cutter, then in conjunction with the outer cutter after entering the top cover at the outlet) ensures thorough dispersion of the material. This design improves the dispersion efficiency and uniformity of the raw material.

[0030] The feeding auger is elastically supported by springs, allowing it to reciprocate back and forth within the feeding trough, thus increasing feeding efficiency. This flexible feeding method helps ensure a continuous and uniform supply of raw materials, while reducing the possibility of blockages and stagnation.

[0031] The feeding auger achieves continuous rotation during its reciprocating motion through the interaction of keyways and keyed teeth on the drive wheel. This design ensures that the feeding auger maintains stable rotation even under complex motion conditions, thereby guaranteeing the continuity and reliability of feeding. Attached Figure Description

[0041] 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.

[0042] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0043] Example 1

[0044] A cement preparation and dispersion processing device includes a body 2, a feed chute 4 installed on one side of the body 2, a feed auger 5 installed inside the feed chute 4, a shell 1 installed above the body 2, a roller cutter 6 rotatably mounted inside the body 2, and a discharge hopper 3 installed below the roller cutter 6. An inner liner 7 is provided inside the body 2 outside the roller cutter 6, and the length of the inner liner 7 is adapted to the length of the roller cutter 6. When the length of the inner liner 7 matches the length of the roller cutter 6, it ensures full contact between the roller cutter 6 and the inner liner 7 during rotation, reducing friction and wear caused by length mismatch. This design helps protect key components of the equipment, improving wear resistance and service life. The adapted length of the inner liner 7 ensures that the material is fully dispersed and crushed under the action of the roller cutter 6. When the roller cutter 6 rotates, its length matches the inner liner 7, which can more effectively cut and grind the material, improving the dispersion effect and crushing efficiency. Because the liner 7 and the roller cutter 6 are matched in length, equipment vibration and noise caused by length mismatch are reduced, which helps to reduce equipment failure rate and improve stability and reliability. The roller cutter 6 is rotatably installed inside the liner 7, which consists of an upper cover 701 and a screen 702. The screen 702 is located below the upper cover 701 and directly above the feed hopper 3. The screen 702 is cleverly positioned below the upper cover 701 to ensure that the raw materials initially crushed by the roller cutter 6 are finely screened by the screen 702 before entering the feed hopper 3. This design can efficiently screen and separate raw materials that meet the particle size standards, effectively preventing large pieces or unqualified raw materials from directly entering the feed hopper 3, thereby improving screening efficiency and product quality. The screen 702 is located directly above the hopper 3, guiding the screened material smoothly into the hopper 3, ensuring the continuity and uniformity of material flow, and effectively preventing material accumulation and blockage at the screen 702 or the hopper 3, thereby improving overall production efficiency. The roller cutter 6 is equipped with a discharge port 601, and outer cutter heads 602 and inner cutter heads 603 are respectively installed on the inner and outer surfaces of the discharge port 601. The inner cutter heads 603 are conically distributed inside the roller cutter 6, breaking up large pieces of raw material. The material then enters the upper cover 701 through the discharge port 601, where it is further broken up by the cooperation of the upper cover 701 and the outer cutter heads 602. The conical design of the inner cutter heads 603 allows the roller cutter 6 to more effectively break up large pieces of raw material when rotating. The conical structure of the inner cutter heads 603 ensures that the raw material is evenly dispersed when subjected to cutting force, preventing accumulation and blockage inside the roller cutter 6. The raw materials are first initially dispersed by the inner cutter head 603, and then enter the upper cover 701 through the discharge port 601, where they cooperate with the outer cutter head 602 for further dispersion. This design optimizes the dispersion process, allowing the raw materials to undergo multiple cuts and grindings to achieve better dispersion.Due to the cooperation between the inner cutter head 603 and the outer cutter head 602, the processing capacity of the equipment is significantly improved. It can more effectively process large and hard raw materials, dispersing them into smaller particles to meet the requirements of subsequent processing. A feed head 604 is installed at one end of the roller cutter 6 inside the machine body 2. A through hole 605 is provided through the feed head 604, and the end of the feed auger 5 is located inside the feed head 604. The end of the feed auger 5 is directly embedded inside the feed head 604, ensuring that the raw material is accurately fed into the roller cutter 6 or other processing devices, reducing leakage and waste during the conveying process, and improving the raw material utilization rate. This design optimizes the transition path of the raw material during the conveying process, reduces the increase in resistance caused by path changes, improves feeding efficiency, and ensures that the raw material can be continuously and stably supplied to the next processing stage. Placing the end of the feed auger 5 inside the feed head 604 also helps reduce the risk of blockage during the raw material conveying process, because when the raw material enters the feed head 604, its flow direction is more clearly guided, avoiding blockage problems caused by poor flow.

[0045] Example 2

[0046] To increase the feeding efficiency of the feed auger 5, for example, such as Figures 1 to 5As shown, the present invention also includes: a spring 506 installed on the feeding auger 5, which provides elastic support for the feeding auger 5, facilitating its reciprocating movement within the feeding trough 4 and increasing feeding efficiency. A limiting block 501 is provided on the feeding auger 5, and the spring 506 is positioned between the limiting block 501 and the feeding trough 4. The limiting block 501 provides a stable support foundation for the spring 506, ensuring its stability and reliability during installation and use. The connection between the spring 506 and the feeding trough 4 via the limiting block 501 achieves elastic support and positioning of the feeding auger 5, effectively preventing excessive offset or shaking during movement and ensuring continuous and accurate feeding. The cooperative design of the limiting block 501 and the spring 506 enhances the connection strength between the feeding auger 5 and the feeding trough 4, making the feeding system more robust and durable. This design helps resist impacts and vibrations during movement, extending the service life of the device. Meanwhile, the design of the limiting block 501 simplifies the installation and adjustment process of the spring 506. The preload of the spring 506 can be adjusted or replaced by adjusting the position of the limiting block 501 without complicated disassembly and reassembly, reducing maintenance difficulty and cost and improving maintenance efficiency. The feeding auger 5 is provided with a keyway 505, and the transmission wheel 502 is limited and installed on the feeding auger 5 through the keyway 505. The transmission wheel 502 is provided with key teeth 503. The transmission wheel 502 slides at the upper limit of the feeding auger 5 through the interaction of the key teeth 503 and the keyway 505. This facilitates the continuous rotation of the feeding auger 5 through the key teeth 503 and the keyway 505 when the feeding auger 5 moves back and forth. The transmission wheel 502 and the bearing seat 504 are both located on the outside of the feeding groove 4. The key teeth 503 inside the transmission wheel 502 are tightly engaged with the keyway 505 of the feeding auger 5. This design ensures that the transmission wheel 502 has excellent transmission stability when driving the feeding auger 5 to rotate. The interaction between the key teeth 503 and the keyway 505 not only provides sufficient driving force but also achieves the limiting function of the feeding auger 5 in its reciprocating motion, effectively preventing deviation or shaking during the movement and ensuring the continuity and accuracy of feeding. The matching design of the key teeth 503 and the keyway 505 significantly enhances the connection strength between the transmission wheel 502 and the feeding auger 5, making the transmission system more robust and durable, effectively resisting impacts and vibrations during the movement, and extending the service life of the device. A bearing seat 504 is provided at one end of the feeding auger 5 located outside the feeding trough 4.

[0047] Working principle:

[0048] Raw materials enter the device through the feed chute 4. Under the elastic support of the spring 506, the feed auger 5 moves back and forth in the feed chute 4. At the same time, the transmission wheel 502 continuously drives the feed auger 5 to rotate through the cooperation of the key tooth 503 and the keyway 505, thereby realizing the continuous and uniform supply of raw materials.

[0049] After the raw material enters the machine body 2, it first comes into contact with the inner cutter head 603 of the roller cutter 6. The inner cutter head 603 is conically distributed inside the roller cutter 6, which can effectively break up large pieces of raw material initially. The broken raw material enters the upper cover 701 through the discharge port 601 of the roller cutter 6. At this time, the raw material comes into contact with the outer cutter head 602. The outer cutter head 602 and the upper cover 701 work together to further break up the raw material and ensure that it is fully dispersed.

[0050] After being broken down by the roller cutter 6, the raw material is sieved through the screen 702. The screen 702 is located below the upper cover 701 and directly above the feed hopper 3, ensuring that only raw materials that meet the particle size requirements pass through the screen 702 and enter the feed hopper 3. Raw materials that do not meet the particle size requirements remain above the screen 702 and undergo further breaking down.

[0051] After screening, the raw materials that meet the particle size requirements are discharged through hopper 3 for further processing.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
