Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a rotary discharger for cement production and processing. Background Art

[0002] Cement rotary dischargers are used in material conveying systems as horizontal, inclined, or vertical feeders. They are particularly suitable for conveying powdered, granular, and small-lump materials such as cement, pulverized coal, and gravel. In the cement industry, they are often used in high-precision dispersion systems during the raw meal homogenization process to achieve ideal mixing, thereby improving clinker quality and saving energy.

[0003] After searching, the patent publication number CN202322644055.3 discloses a rotary discharger for cement production and processing. Although the device includes a support shell, a rotary drive unit and a rotating shaft by setting a discharge component during use, the rotating shaft is located inside the support shell, the rotary drive unit is installed outside the support shell, the output shaft of the rotary drive unit is connected to the rotating shaft, and the water-passing component includes an adapter plate, a junction box, a transmission pipe and an inlet pipe. The adapter plate is connected to the support shell, the junction box is connected to the adapter plate, and multiple transmission pipes are connected to the junction box. The transmission pipe passes through the side wall of the support shell, and the inlet pipe is connected to the junction box. However, the device will generate a large amount of dust when in use. If the rotary discharger cannot effectively isolate dust leakage, it will cause wear to the rotary discharger itself and peripheral equipment. The dust particles constantly rub inside the equipment, which will accelerate the aging and damage of the equipment and shorten the life of the equipment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a rotary discharger for cement production and processing, which solves the problems raised in the background technology.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] A rotary discharger for cement production and processing comprises an upper discharge assembly, wherein a lower discharge assembly is installed below the upper discharge assembly;

[0007] A first transmission shaft is rotatably mounted inside the upper discharge assembly, a first synchronous wheel is fixed to one end of the first transmission shaft, a second transmission shaft is rotatably mounted inside the lower discharge assembly, a second synchronous wheel is mounted on the outer side of the lower discharge assembly, and the second synchronous wheel is connected to the first synchronous wheel through a synchronous belt transmission;

[0008] The first transmission shaft is located inside the upper discharge assembly and is provided with a first valve plate, and the second transmission shaft is located inside the lower discharge assembly and is provided with a second valve plate, and the angle difference between the first valve plate and the second valve plate is forty-five degrees.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the second transmission shaft is in transmission connection with an external power device.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The direct drive connection between the second drive shaft and the external power unit ensures efficient power transmission. This connection reduces power loss during transmission and improves overall system efficiency. The direct connection between the second drive shaft and the external power unit simplifies the transmission system structure, making it more compact. This not only facilitates equipment layout and installation, but also reduces equipment space and improves the overall layout efficiency of the production line.

[0013] Furthermore, there are four first valve plates and four second valve plates respectively, and the angle between the four first valve plates is ninety degrees, and the angle between the four second valve plates is also ninety degrees. The angle difference between the first valve plates and the second valve plates is used to make the upper unloading assembly and the lower unloading assembly alternately closed during unloading.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] Because there are four first and second valve plates, and the angles between them are all 90 degrees, the angle difference between them allows for alternating closure of the upper and lower discharge assemblies. This alternating closure design allows material to be continuously discharged from the equipment, improving discharge efficiency. This alternating closure ensures that at least one discharge port is always closed during discharge from the upper and lower discharge assemblies. This design effectively prevents dust leakage during transport, protecting the production environment. Dust leakage not only pollutes the production environment but also causes wear and corrosion to the equipment. By enhancing sealing performance, this design reduces dust damage to the equipment, thereby extending its service life.

[0016] Furthermore, a first feed port is provided at the top end of the upper discharge assembly, and a first discharge port is provided at the bottom end of the upper discharge assembly.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The feed port is located at the top of the upper discharge assembly, allowing materials to flow naturally into the equipment using gravity. This design helps reduce blockage and accumulation during the feeding process and improves unloading. Once material enters the equipment from the top, it is more evenly distributed throughout the equipment, preventing localized accumulation and excessive wear. This helps extend the equipment's service life and improve production efficiency.

[0019] Furthermore, a second feed port is provided at the top end of the lower discharge assembly, a second discharge port is provided at the bottom end of the lower discharge assembly, and the upper discharge assembly is connected to the second feed port through the first discharge port.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] This design ensures continuous material flow from the upper discharge assembly to the lower discharge assembly. When the first valve plate is opened, material flows smoothly from the upper discharge assembly's first outlet to the lower discharge assembly's second inlet, achieving seamless material transfer. The interconnected design of the upper and lower discharge assemblies reduces the risk of external interference during material transfer, ensuring stable material transport. This design eliminates waiting and stagnation during material transfer, reducing equipment waiting time and improving operational efficiency. This continuous and stable material flow helps maintain efficient production, thereby increasing overall production capacity.

[0022] Furthermore, the upper discharge assembly and the lower discharge assembly are fixed by bolts and nuts.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] Another significant advantage of bolt and nut connections is ease of installation and disassembly. During equipment installation, simply insert the bolts through the pre-determined holes in the upper discharge assembly and tighten the nuts to secure it. Similarly, to disassemble the equipment, simply loosen the nuts and remove the bolts. This simple installation method not only improves work efficiency but also reduces installation costs. Because bolt and nut connections are easy to disassemble, when equipment requires repair or component replacement, the upper or lower discharge assembly can be conveniently removed for internal inspection, repair, or replacement. This design helps extend the service life of the equipment and reduces maintenance costs.

[0025] Furthermore, a second support seat is installed at one end of the upper unloading assembly and the lower unloading assembly respectively, and a bearing seat is installed on the upper unloading assembly and the lower unloading assembly through the second support seat, and a fixing pin is installed on the bearing seat of the upper unloading assembly and the lower unloading assembly. When the first transmission shaft and the second transmission shaft are not in use, they are locked and fixed by the fixing pin.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] By installing a second support seat at one end of the upper and lower discharge assemblies, and mounting a bearing seat on the support seat, the drive shaft can be effectively supported and secured, ensuring its stability and reliability during operation. When the drive shaft is not in use, the bearing seat is locked and secured with a retaining pin, further preventing the drive shaft from loosening or shifting, thereby improving the stability of the entire equipment. The retaining pin design makes it easier and quicker to remove or install the drive shaft. The drive shaft can be secured or released by simply loosening or inserting the retaining pin. Locking and securing the drive shaft with the retaining pin allows for easy inspection and maintenance of components such as the bearing seat, support seat, and drive shaft, reducing maintenance costs and time.

[0028] The utility model provides a rotary discharger for cement production and processing. It has the following beneficial effects:

[0029] The upper and lower discharge assemblies are secured together with bolts and nuts. This design makes assembly and disassembly of the equipment simple and quick, facilitating maintenance and replacement. The modular design also enhances the flexibility and scalability of the equipment.

[0030] The first and second synchronous wheels and the synchronous belt are connected to achieve stable power transmission. This transmission method is not only highly efficient, but also reduces energy loss and improves the overall operating efficiency of the equipment.

[0031] The special design between the first and second valve plates—a 45-degree angle difference between them, and a 90-degree angle between the four valve plates—enables the upper and lower discharge assemblies to alternately close during discharge, effectively preventing dust leakage. This is crucial in dusty environments like cement production.

[0032] The device is equipped with a fixing pin that can be locked when the first and second transmission shafts are not in use, thus ensuring the stability and safety of the device when it is not in operation. In addition, the design of the bearing seat and support seat also enhances the stability and durability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example 1

[0044] A rotary discharger for cement production and processing comprises an upper discharge assembly 1 with a lower discharge assembly 2 mounted below the upper discharge assembly 1. The upper and lower discharge assemblies 1 and 2 are secured together by bolts and nuts. Another significant advantage of this bolt-and-nut connection is its ease of installation and removal. During equipment installation, the bolts are simply threaded through the pre-recorded holes in the upper discharge assembly 1 and tightened with the nuts. Similarly, to dismantle the equipment, the nuts are simply loosened and the bolts removed. This simple installation method not only improves work efficiency but also reduces installation costs. Because the bolt-and-nut connection is easy to remove, the upper or lower discharge assembly 1 and 2 can be conveniently removed for internal inspection, repair, or replacement when equipment maintenance or component replacement is required. This design helps extend the service life of the equipment and reduce maintenance costs. A first feed inlet 104 is provided at the top of the upper discharge assembly 1, and a first discharge outlet 105 is provided at the bottom. Positioning the feed inlet at the top of the upper discharge assembly 1 allows material to flow naturally into the equipment by gravity. This design helps reduce material blockage and accumulation during the feeding process, thereby improving the smoothness of material discharge. After entering the equipment from the top, the material can be more evenly distributed within the equipment, avoiding localized accumulation and excessive wear. This helps extend the service life of the equipment and improve production efficiency. The top of the lower discharge assembly 2 is provided with a second feed port 204, and the bottom of the lower discharge assembly 2 is provided with a second discharge port 205. The upper discharge assembly 1 is connected to the second feed port 204 via the first discharge port 105. This design ensures the continuous flow of material from the upper discharge assembly 1 to the lower discharge assembly 2. When the first valve plate 103 is opened, the material can smoothly enter the second feed port 204 of the lower discharge assembly 2 from the first discharge port 105 of the upper discharge assembly 1, achieving seamless material connection. Because the upper and lower discharge assemblies 2 are connected, the material is not easily disturbed by external factors during the transmission process, thus ensuring the stability of material transmission. This design avoids waiting and stagnation of materials during transmission, reduces the waiting time of the equipment, and improves the operating efficiency of the equipment. Continuous and stable material flow helps the equipment maintain efficient production, thereby improving overall production capacity. A first transmission shaft 101 is rotatably mounted within the upper discharge assembly 1, with a first synchronous pulley 102 secured to one end. A second transmission shaft 201 is rotatably mounted within the lower discharge assembly 2. This second transmission shaft 201 is connected to an external power source via a direct drive connection, ensuring efficient power transmission. This connection significantly reduces power losses within the transmission chain, thereby improving the overall efficiency of the transmission system. By directly connecting the second transmission shaft 201 to the external power source, the transmission system's structure is simplified, making it more compact.This not only optimizes the layout and installation process of the equipment, but also effectively reduces the space occupied by the equipment, thereby improving the overall layout efficiency of the production line. The second transmission shaft 201 is located on the outside of the lower unloading component 2 and is equipped with a second synchronous wheel 202. The second synchronous wheel 202 is connected to the first synchronous wheel 102 through a synchronous belt 4. The upper unloading component 1 and the lower unloading component 2 are respectively equipped with a second support seat 6 at one end. The upper unloading component 1 and the lower unloading component 2 are equipped with a bearing seat 7 through the second support seat 6, and a fixing pin 5 is installed on the bearing seat 7 of the upper unloading component 1 and the lower unloading component 2. The ends of the first transmission shaft 101 and the second transmission shaft 201 are located in the bearing seat 7. When the first transmission shaft 101 and the second transmission shaft 201 are not in use, they are locked and fixed by the fixing pin 5. By respectively installing the second support seat 6 at one end of the upper unloading component 1 and the lower unloading component 2, and installing the bearing seat 7 on the support seat, the transmission shaft can be effectively supported and fixed, ensuring its stability and reliability during operation. When the drive shaft is not in use, the bearing seat 7 is locked and secured with the retaining pin 5, further preventing the drive shaft from loosening or shifting, thereby enhancing the stability of the entire device. The design of the retaining pin 5 makes it easier and quicker to remove or install the drive shaft. Simply loosen or insert the retaining pin 5 to secure or release the drive shaft. Locking the drive shaft with the retaining pin 5 facilitates inspection and maintenance of components such as the bearing seat 7, support base, and drive shaft, reducing maintenance costs and time.

[0045] Example 2

[0046] In order to increase the sealing of the equipment and prevent dust leakage, for example, Figures 1 to 4As shown, the present invention also includes: a first transmission shaft 101 is located inside the upper discharge assembly 1 and is provided with a first valve plate 103; a second transmission shaft 201 is located inside the lower discharge assembly 2 and is provided with a second valve plate 203; the angle difference between the first valve plate 103 and the second valve plate 203 is 45 degrees; there are four first valve plates 103 and four second valve plates 203, and the angle between the four first valve plates 103 is 90 degrees, and the angle between the four second valve plates 203 is also 90 degrees. The angle difference between the first valve plates 103 and the second valve plates 203 is used to alternately close the upper discharge assembly 1 and the lower discharge assembly 2 during material discharge, thereby preventing dust leakage. Since there are four first valve plates 103 and the second valve plates 203, and the angle between them is 90 degrees, the angle difference between them can be used to achieve the alternating sealing function of the upper discharge assembly 1 and the lower discharge assembly 2. This alternating sealing design ensures that materials can be continuously discharged from the equipment, thereby improving material discharge efficiency. This design uses alternating sealing to ensure that at least one discharge port remains closed during material discharge between the upper discharge assembly 1 and the lower discharge assembly 2. This effectively prevents dust leakage during transport and protects the production environment. Dust leakage not only pollutes the production environment but also accelerates wear and corrosion of equipment. This design enhances sealing performance, reduces dust damage to the equipment, and thus extends its service life.

[0047] Working principle:

[0048] An external power device (such as a motor) drives the second transmission shaft 201 to rotate via a transmission connection (such as a chain, gears, or belt, but specifically a timing belt 4 in this embodiment). The second synchronous pulley 202 on the second transmission shaft 201 and the first synchronous pulley 102 on the first transmission shaft 101 are synchronously driven via the timing belt 4, thereby driving the first transmission shaft 101 to rotate.

[0049] As the first transmission shaft 101 and the second transmission shaft 201 rotate, they respectively drive the rotation of the first valve plate 103 in the upper discharge assembly 1 and the second valve plate 203 in the lower discharge assembly 2. The rotation of the first valve plate 103 and the second valve plate 203 enables them to alternately close and open the discharge ports of the upper discharge assembly 1 and the lower discharge assembly 2, thereby achieving continuous material discharge.

[0050] Material enters the upper discharge assembly 1 through the first feed port 104 at the top of the upper discharge assembly 1. When the first valve plate 103 is open, the material enters the second feed port 204 of the lower discharge assembly 2 through the first discharge port 105 of the upper discharge assembly 1. At the same time, the second valve plate 203 is closed, preventing material from leaking out of the second discharge port 205 of the lower discharge assembly 2.

[0051] As the first transmission shaft 101 and the second transmission shaft 201 continue to rotate, when the second valve plate 203 is in the open state, the material is discharged from the second discharge port 205 of the lower discharge assembly 2. At this time, the first valve plate 103 is in the closed state, ensuring that the material does not flow back or leak from the first discharge port 105 of the upper discharge assembly 1.

[0052] Because there is a certain angle difference (45 degrees) between the first valve plate 103 and the second valve plate 203, and there are four of them with an included angle of 90 degrees, they can alternately close the discharge port during the unloading process of the upper discharge assembly 1 and the lower discharge assembly 2. This alternating sealing design effectively prevents dust from leaking during the transportation process.

[0053] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
