Description

Technical Field

[0001] This utility model relates to the field of shaping equipment technology, specifically to a shaping and spheroidizing device that uses a single fan to control the separation of finished products and tail materials. Background Technology

[0002] Shaping machines are widely used material handling equipment in industries such as chemicals, dyes, coatings, rubber, pharmaceuticals, food, and non-metallic minerals. They are mainly used for crushing, shaping, and grading materials. Traditional shaping systems typically employ two independent suction systems, one for finished product dust removal and the other for tailings dust removal. While this design is functionally complete, it suffers from high equipment costs, large space requirements, and is not conducive to energy conservation, emission reduction, or system integration. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a shaping and spheroidizing device that separates finished products and tail materials under the control of a single fan.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A shaping and spheroidizing device for separating finished and tail materials by a single fan includes a raw material silo, a shaping machine, a finished product dust collector, and a tail material dust collector; the discharge port at the bottom of the raw material silo is connected to the inlet of the shaping machine through a feeding mechanism, and the fine powder discharge port of the classifier built into the top of the shaping machine is connected to the air inlet of the tail material dust collector through a pipe. The finished product outlet of the shaping machine is connected to the air inlet of the finished product dust collector via a pipe; The finished product dust collector's outlet is connected to a finished product outlet pipe, which is connected to a finished product pneumatic valve; the tail material dust collector's outlet is connected to a tail material outlet pipe, which is connected to a tail material pneumatic valve; the free ends of the finished product outlet pipe and the tail material outlet pipe converge and are connected to the exhaust port of a negative pressure fan; by switching the opening and closing of the finished product pneumatic valve and the tail material pneumatic valve, the finished product and tail material are separated and conveyed.

[0005] Furthermore, the finished product exhaust pipe is also connected to a finished product electric air valve; the tail material exhaust pipe is also connected to a tail material electric air valve.

[0006] Furthermore, the feeding mechanism is a screw conveyor.

[0007] Furthermore, the raw material silo includes, from top to bottom, a pneumatic feeding silo, a buffer silo, and a metering silo connected in sequence, and the outlets of the pneumatic feeding silo, the buffer silo, and the metering silo are all equipped with discharge valves.

[0008] Furthermore, the shaping and spheroidizing device is controlled by a PLC controller to regulate the shaping cycle.

[0009] By adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. The adoption of a single-fan system replaces the traditional two independent suction systems, directly reducing the number of fan cores. This not only lowers initial equipment investment but also achieves long-term energy conservation and emission reduction. The system structure is more compact, reducing the space occupied by the equipment and making it easier to install and layout in existing production workshops.

[0010] 2. Employing a PLC-controlled intermittent shaping mode, users can flexibly set and adjust the shaping time according to the characteristics of different materials (such as hardness, initial particle size, etc.) to achieve the best shaping effect, thereby effectively removing the sharp edges of particles and achieving a rounded particle shape. The entire machine's workflow (feeding, shaping, grading, finished product / tailing separation, and discharge) is automatically controlled by PLC, with each link closely connected, realizing efficient batch cyclic production, stable operation, and reducing human intervention.

[0011] 3. By precisely controlling the feed amount of each batch through the metering bin, the system provides stable working conditions and ensures the uniformity and consistency of the final product particle size.

[0012] 4. The air volume to the finished product dust collector and the tail material dust collector can be adjusted independently and flexibly through the electric air valve, thereby optimizing the separation efficiency and achieving precise control according to the process requirements of different materials. Attached Figure Description

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Figure 1 This is a front view schematic diagram of the present utility model; Figure 2 This is a top view of the present invention; Figure 3 for Figure 1 A schematic diagram of direction A (only the pipe section is shown). Detailed Implementation

[0014] like Figure 1-3 As shown, the shaping and spheroidizing device for separating finished products and tail materials by controlling a single fan provided in this embodiment includes a raw material silo, a shaping machine 6, a finished product dust collector 8, and a tail material dust collector 7.

[0015] The raw material silo is used for material storage and quantitative supply. In this embodiment, the raw material silo adopts a three-level structure, including, from top to bottom, a pneumatic feeding silo 1, a buffer silo 3, and a metering silo 4 connected in sequence. The inlet of the pneumatic feeding silo 1 is connected to the pneumatic feeding system for receiving materials. The outlets of the pneumatic feeding silo 1, the buffer silo 3, and the metering silo 4 are all equipped with discharge valves, and their opening and closing are controlled by a PLC controller to achieve progressive buffering and precise metering of materials, ensuring that the weight of each batch of materials entering the shaping machine remains constant.

[0016] The discharge port at the bottom of the metering chamber 4 is connected to the inlet of the shaping machine 6 via the feeding mechanism 5. In this embodiment, the feeding mechanism 5 is preferably a screw conveyor, which can stably, evenly and in a sealed manner feed the material into the shaping machine 6.

[0017] The shaping machine 6 is a vertical shaping chamber, inside which are installed high-speed rotating wear-resistant alloy hammers driven by a motor. A classifier is built into the top of the shaping machine 6. The fine powder outlet of the classifier built into the top of the shaping machine 6 is connected to the air inlet of the tailing dust collector 7 via a pipe; the finished product outlet of the shaping machine 6 is connected to the air inlet of the finished product dust collector 8 via a pipe. During the shaping process, coarser particles continue to be hammered and rubbed against each other within the chamber. The built-in classifier operates at a high speed, simultaneously shaping and extracting fine powder. The fine powder (i.e., tailings) is separated by the classifier and drawn from the fine powder outlet at the top of the classifier into the tailing dust collector 7. After shaping is complete, the finished product outlet valve 61 is opened, and the finished product is drawn from the finished product outlet of the shaping machine 6 into the finished product dust collector 8. After the finished product is conveyed, the finished product outlet valve is closed, and feeding can begin again, repeating the process.

[0018] The core innovation of this utility model lies in its single-fan airflow system: The air outlet of the finished dust collector 8 is connected to the finished air outlet pipe 11, and the finished air outlet pipe 11 is connected in sequence to the finished electric air valve 10 and the finished pneumatic air valve 12.

[0019] The tail material dust collector 7 is connected to a tail material outlet pipe 9, and a tail material electric air valve 10 and a tail material pneumatic air valve 13 are connected in sequence on the tail material outlet pipe 9.

[0020] The free ends (i.e., downstream ends) of the finished product exhaust pipe 11 and the tail material exhaust pipe 9 converge and are connected to the exhaust port of a negative pressure fan 2. The exhaust port of the negative pressure fan 2 can be connected to the atmosphere or subsequent treatment equipment.

[0021] In this embodiment, all electric and pneumatic components of the shaping and spheroidizing device (such as each discharge valve, feeding mechanism, shaping machine, air valve, etc.) are electrically connected to the PLC controller, which controls the automated operation of the entire shaping cycle according to a preset program.

[0022] The specific workflow of this utility model is as follows: Feeding and shaping stage: The main motor of the shaping machine 6 is started, causing the hammers to rotate at high speed. Simultaneously, the built-in classifier starts and maintains a high speed. The PLC controller opens the tail material pneumatic valve 13 while closing the finished product pneumatic valve 12. The negative pressure fan 2 continues to operate, generating negative pressure in the tail material dust collection pipeline. The PLC controller opens the discharge valve at the bottom of the metering chamber 4 and starts the screw conveyor, feeding a predetermined amount of material into the shaping machine 6. The fine powder (tail material) generated during the shaping process is selected by the built-in classifier and immediately sucked into the tail material dust collector 7 for collection. At this time, the opening degree of the tail material electric valve 10 can be adjusted according to the amount of tail material generated to control the optimal separation airflow.

[0023] Finished product output stage: After the preset shaping time is reached, the PLC controller first opens the finished product pneumatic air valve 12 and then closes the tail material pneumatic air valve 13. Through this "open-then-close" switching of pneumatic air valves, the air path to the tail material dust collector is precisely cut off, and the air path to the finished product dust collector is established.

[0024] Simultaneously, the finished product discharge valve 61 of the shaping machine 6 opens. The finished product material that has been shaped and meets the particle size requirements is rapidly drawn into the finished product dust collector 8 under negative pressure and collected. At this time, the opening degree of the finished product electric air valve 10 can be adjusted according to the characteristics of the finished product material to control the optimal conveying air volume and avoid pipe blockage or broken particles.

[0025] Preparation phase of the cycle: After the finished product is conveyed, the PLC controller closes the finished product pneumatic valve 12 and the finished product discharge valve 61 of the shaping machine 6. The system returns to its initial state, ready for the next batch of feeding and shaping, repeating this process to achieve continuous automated production.

[0026] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
