Description

Technical Field

[0001] This application relates to the field of calcined gypsum powder cooling technology, for example to a ventilation cooling cone for calcined industrial by-product gypsum powder. Background Technology

[0002] In the calcination process of gypsum powder, the calcined powder has a strong thermal shock and unstable phase composition. If the powder is not cooled to reduce its temperature, the stability of the final product quality cannot be guaranteed. This can lead to the finished powder accumulating heat and continuing to dehydrate and "over-burning" when transported to the storage silo. In addition, the particulate impurities in the raw materials cannot be screened and removed, affecting the purity of the finished product. Furthermore, the formulation of the powder as an additive for downstream products such as gypsum-based plastering and self-leveling products is uncontrollable, affecting its usability and workability.

[0003] Existing cooling equipment generally involves placing the roasted powder in large containers after production and then cooling it with airflow, or using water cooling in the container. Whether using airflow or indirect water cooling, both methods suffer from high manufacturing costs, high power consumption, and poor cooling performance. Utility Model Content To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0004] This disclosure provides a ventilation cooling cone for calcined industrial by-product gypsum powder to solve the problems of high equipment cost and poor cooling effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A ventilation cooling cone for calcined gypsum powder, a by-product of industrial production, includes a cooling cone body. The cooling cone body mainly comprises a collection bin, a flow-guiding buffer cone, a distribution bin, a V-shaped distributor, a drip feeder, an expansion bin, and a coarse material collection bin. The collection bin is a cylindrical structure with a flow-guiding buffer cone inside. The top of the flow-guiding buffer cone is fixedly connected to the top and bottom of the collection bin. The bottom of the collection bin is fixedly connected to the distribution bin, which contains a V-shaped distributor. Material guided and conveyed by the flow-guiding buffer cone flows into the V-shaped distributor within the distribution bin. The V-shaped distributor is driven by a drive motor fixedly located on the top side of the collection bin. The drive motor drives the drive shaft of the V-shaped distribution bin via a transmission belt. Under the action of the V-shaped distributor, the material is evenly distributed. The material is dispersed in a cylindrical hopper with a conical bottom. A drip feeder is installed at the bottom of the hopper. The material is dispersed by centrifugal force through a V-shaped distributor and finally flows into the drip feeder within the hopper. The drip feeder is designed for stratified dripping to ensure more thorough diffusion of the gypsum powder. Each layer of the drip feeder is connected to an expansion chamber on both sides. The expansion chamber is located inside the functional hopper, and its top is connected to the outer wall of the hopper, creating a connection. The stratified dripping further collects the material into the corresponding expansion chamber. The expansion chamber walls are equipped with turbine blades. High-pressure air mixes the material within the expansion chamber, creating a material mixing airflow. Simultaneously, larger coarse particles slide into a coarse material collection chamber under gravity. The mixed material air is dispersed and guided into the storage silo by the wind to complete the operation. During the above process, the device collects the material through the guide buffer cone, then spreads and distributes it through the V-shaped distributor, and finally drips it in layers through the drip machine to the expansion silo for mixing and air delivery. This can effectively screen and cool the calcined high-temperature powder, which not only improves the purity of the finished powder and separates large particles, but also reduces the temperature of the material, thereby increasing the phase composition stability of the finished material. This can effectively improve the workability and practicality of the powder used in downstream products.

[0006] Furthermore, the top side of the silo is provided with a feed inlet, and the dihydrate gypsum is calcined into high-temperature cooked powder by a calciner and then fed into the guide buffer cone through the feed inlet by a conveying device.

[0007] Furthermore, the V-shaped material distributor has a cylindrical and conical structure with a backflow vane at the bottom, which allows for more thorough material distribution.

[0008] Furthermore, a circulating fan is connected to one side of the bottom of the functional compartment. The circulating fan blows air into the functional compartment, and the airflow rotates in the functional compartment to form centrifugal air, which blows the material to the top of the device and blows it out from the discharge port. The circulating fan is connected to an air inlet pipe, which is connected to the functional compartment.

[0009] Furthermore, the coarse material collection bin is connected to the bottom of the functional bin, and a heavy hammer airlock is installed at the bottom of the coarse material collection bin (the heavy hammer airlock is also known as a heavy hammer type flap airlock valve or double-layer airlock valve, which is a device that uses the weight of the material to achieve automatic unloading). After the coarse material is collected to a certain extent, the heavy hammer airlock will open and discharge the coarse material into the particle collection bin, which is located at the bottom of the coarse material collection bin for holding the coarse material.

[0010] Furthermore, a discharge port is provided on one side of the collection bin, and the discharge port is connected to a conveying pipe. The material mixing air will be output from the discharge port and travel in the conveying pipe. The conveying pipe is connected to several cyclone collectors, and the material and air are separated by the cyclone collectors.

[0011] Furthermore, each cyclone collector is connected to a storage silo at its bottom. The mixed material air undergoes material-air separation through the cyclone collector, and the separated material is transported to the storage silo at the bottom through the cyclone collector. The top of the cyclone collector is connected to a return air pipe, and the separated air is rotated and transported back to the return air pipe. The return air pipe is connected to a circulating fan and, after being processed, is transported back to the functional chamber to achieve air circulation. A make-up air valve is installed near the circulating fan on the return air pipe to control the gas compensation in the return air pipe, so as to maintain the air pressure in the entire device and ensure operating efficiency.

[0012] Furthermore, a dust collector is installed on one side of the top of the storage silo. The material in the storage silo will undergo further gas-solid separation through the dust collector, and excess gas will be discharged from the storage silo. A manual gate valve is installed at the bottom of the storage silo, and level gauges are installed at the top and bottom of its internal sidewalls. The level gauges detect the amount of material inside the storage silo. When the material reaches the detection position of the top level gauge, the manual gate valve can be opened to discharge the material. When the material is discharged to the detection position of the bottom level gauge, the discharge can be stopped and the manual gate valve can be closed.

[0013] The drip machine, the counterweight airlock, the make-up air valve, and the dust collector are all existing technologies. Those skilled in the art can clearly and correctly understand this utility model and can obtain the relevant technologies from existing materials.

[0014] The ventilation and cooling cone for calcined gypsum powder, a by-product of industrial production, provided in this embodiment can achieve the following technical effects: This device collects materials through a guide buffer cone, then spreads and distributes them through a V-shaped distributor, and finally drips them in layers through a dripper to the expansion chamber for mixing and air supply. This effectively screens and cools the calcined high-temperature powder, improving the purity of the finished powder by separating large particles and reducing the temperature of the material. This increases the stability of the phase composition of the finished material, thereby effectively improving the workability and practicality of the powder used in downstream products.

[0019] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0020] A ventilation and cooling cone for calcined gypsum powder, a byproduct of industrial production, includes a cooling cone 1. The cooling cone 1 mainly comprises a collection bin 11, a flow-guiding and buffering cone 12, a material distribution bin 13, a V-shaped material distributor 14, a drip feeder 15, an expansion bin 16, and a coarse material collection bin 17. The collection bin 11 has a cylindrical structure and is internally equipped with the flow-guiding and buffering cone 12. The top of the flow-guiding and buffering cone 12 is fixedly connected to the bottom of the top of the collection bin 11. An inlet 111 is provided on the top side of the collection bin 11. After dihydrate gypsum is calcined into high-temperature powder by a calciner, it is fed into the flow-guiding and buffering cone through the inlet 111 via a conveying device. Inside the 12, the bottom of the collection bin 11 is fixedly connected to the distribution bin 13. The distribution bin 13 is equipped with a V-shaped distributor 14. The material conveyed by the guide buffer cone 12 will flow into the V-shaped distributor 14 in the distribution bin 13. The V-shaped distribution bin 13 is driven by a drive motor 19. The drive motor 19 is fixedly installed on the top side of the collection bin 11. The drive motor 19 drives the drive shaft of the V-shaped distribution bin 13 through the transmission belt. The V-shaped distributor 14 has a cylindrical and conical structure and is equipped with a backflow vane 141 at the bottom. The backflow vane 141 can distribute the material more fully.

[0021] Under the action of the V-shaped distributor 14, the material is evenly distributed in the distribution bin 13. The distribution bin 13 is cylindrical with a conical bottom. A drip feeder 15 is installed at the bottom of the distribution bin 13. The material is dispersed under centrifugal force by the V-shaped distributor 14 and finally flows into the drip feeder 15 within the distribution bin 13. The drip feeder 15 is designed with layered dripping to facilitate more thorough diffusion of the gypsum powder. Each layer of the drip feeder 15 is connected to an expansion bin 16 on both sides. The expansion bin 16 is located inside the functional bin 162. The top of the functional bin 162 is connected to the outer wall of the distribution bin 13, making them interconnected. A circulating fan 9 is connected to one side of the bottom of the functional bin 162. The circulating fan 9 blows air into the functional bin 162. The airflow in the functional bin 162 rotates and forms centrifugal air, which blows the material to the top of the device and out through the discharge port 112. The circulating fan 9 is connected to the air inlet pipe 18, which connects to the functional chamber 162. The material is further collected into the corresponding expansion chamber 16 by the dripping machine 15 through layered dripping. The expansion chamber 16 is equipped with turbine blades 161 on its walls. In the expansion chamber 16, the material is mixed with high-pressure air to form a material mixing air. At the same time, larger coarse particles will slide into the coarse material collection chamber 17 under the action of gravity. The coarse material collection chamber 17 is connected to the bottom of the functional chamber 162. The bottom of the coarse material collection chamber 17 is equipped with a heavy hammer airlock 171 (also known as a heavy hammer type flap airlock valve or double-layer airlock valve, which is a device that uses the weight of the material to achieve automatic unloading). After the coarse material is collected to a certain extent, the heavy hammer airlock 171 will open and discharge the coarse material into the particle collection chamber 2. The particle collection chamber 2 is located at the bottom of the coarse material collection chamber 17 and is used to hold the coarse material.

[0022] The mixed material air is dispersed and guided into the storage silo 7 by the wind force to complete the operation. A discharge port 112 is provided on one side of the collection silo 11, which is connected to a conveying pipe 5. The mixed material air is output from the discharge port 112 and travels within the conveying pipe 5. The conveying pipe 5 is connected to several cyclone collectors 3, which separate the material from the air. Each cyclone collector 3 is connected to a storage silo 7 at its bottom. After the mixed material air passes through the cyclone collectors 3 for separation, the separated material is conveyed through the cyclone collectors 3 to the storage silo 7 at the bottom. A return air pipe 4 is connected to the top of each cyclone collector 3. The separated air is then conveyed back into the return air pipe 4, which is connected to a circulating fan 9 and, after processing, is reintroduced into the functional silo 162. To achieve air circulation, a make-up air valve 41 is installed near the circulating fan 9 in the return air duct 4. The make-up air valve 41 controls the gas compensation in the return air duct 4 to maintain the air pressure in the entire device and ensure operating efficiency. A dust collector 8 is installed on one side of the top of the storage silo. The material in the storage silo 7 will undergo further gas-solid separation through the dust collector 8 to discharge excess gas from the storage silo 7. A manual gate valve 71 is installed at the bottom of the storage silo 7, and level gauges 6 are installed at the top and bottom of its internal sidewall. The level gauges 6 detect the amount of material inside the storage silo 7. When the material reaches the detection position of the top level gauge 6, the manual gate valve 71 can be opened to discharge the material. When the material is discharged to the detection position of the bottom level gauge 6, the discharge can be stopped and the manual gate valve 71 can be closed.

[0023] In the above process, the device collects the material through the guide buffer cone 12, then spreads and distributes it through the V-shaped distributor 14, and finally drips it in layers through the dripper 15 to the expansion chamber 16 for mixing and air supply. This can effectively screen and cool the calcined high-temperature powder, which not only improves the purity of the finished powder and separates large particles of coarse material, but also reduces the temperature of the material, thereby increasing the phase composition stability of the finished material. This can effectively improve the workability and practicality of the powder used in downstream products.

[0024] The dripping machine 15, the counterweight airlock 171, the make-up air valve 41, and the dust collector 8 are all existing technologies. Those skilled in the art can clearly and correctly understand this utility model and can obtain the relevant technologies from existing materials.

Some parts and features of some embodiments may be included or replaced by parts and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from its scope. The scope of the present disclosure is limited only by the appended claims.
