Description

Technical Field

[0001] This utility model relates to the field of material feeding equipment technology, and in particular to a feeding device with good sealing performance. Background Technology

[0002] In the production processes of many industries such as chemical, food, pharmaceutical, and building materials, feeding devices are key equipment for achieving automated material conveying. Their main function is to stably and efficiently transport raw or semi-finished materials to subsequent processing equipment. The sealing performance of the feeding device directly affects the stability and safety of material conveying, as well as the quality of the production environment. Traditional feeding devices often suffer from poor sealing performance during material conveying. This is especially true at the connection between the feeding pipe and the material conveying pipe, which typically uses a single flange and bolts, relying solely on gaskets between the flanges for sealing. Over long-term use, these gaskets are prone to wear and aging, losing their sealing effectiveness and leading to material leakage. This not only wastes materials but can also pollute the production environment; if flammable, explosive, toxic, or hazardous materials are being conveyed, leaks can cause safety accidents and threaten the lives of workers. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device with good sealing performance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A well-sealed feeding device includes a base, with a feeding machine body fixedly connected to the upper end of the base, and a pump body installed at the lower end of the base. The pump body is connected to the feeding machine body, and a feeding pipe is installed at the discharge end of the pump body. The feeding pipe is connected to a material conveying pipe via a connector, which consists of a first flange and a second flange. A first retaining ring is fixedly connected to the end of the first flange near the second flange, and a second retaining ring that mates with the first retaining ring is fixedly connected to the second flange. A groove is formed at the end of the first retaining ring, and a first sealing ring is installed on the inner wall of the groove. A sealing groove that mates with the groove is formed on the second retaining ring, and a connecting groove that mates with the first sealing ring is formed on the inner wall of the sealing groove.

[0005] Preferably, the first retaining ring has a retaining groove, and the end of the second retaining ring has an inclined surface that matches the retaining groove.

[0006] Preferably, a second sealing ring is installed at the end of the first retaining ring near the sealing groove.

[0007] Preferably, both the first flange and the second flange have multiple mounting screw holes that are circumferentially and equally spaced.

[0008] Preferably, the lower end of the base is fixedly connected to four support legs arranged in a rectangular pattern.

[0009] Compared with the prior art, the advantages of this utility model are as follows: 1. By setting a double sealing structure between the first and second retaining rings of the connector, namely the first seal formed by the first sealing ring and the connecting groove, and the second seal formed by the second sealing ring, the sealing performance of the connection between the feed pipe and the material conveying pipe is greatly improved, effectively avoiding material leakage, reducing material waste, protecting the production environment, and reducing the risk of safety accidents caused by material leakage.

[0010] 2. The bevel at the end of the second retaining ring cooperates with the groove on the first retaining ring, which not only facilitates the quick positioning and alignment of the first and second retaining rings during installation, but also enhances the interlocking stability after the two are connected, preventing misalignment of the connection part due to vibration and other factors during material conveying, and further ensuring the sealing effect.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0014] Reference Figure 1-4 A well-sealed feeding device includes a base 2 made of high-strength stainless steel, which has good load-bearing capacity and corrosion resistance, and can effectively support the weight of the entire device. Four rectangular support legs 3 are fixedly connected to the lower end of the base 2. The support legs 3 are also made of stainless steel, and anti-slip rubber pads are installed at the lower end of the support legs 3 to further enhance the stability of the device and prevent slippage during operation. The upper end of the base 2 is fixedly connected to the feeder body 1 by welding. The feeder body 1 is a cylindrical structure with a storage chamber inside for storing the material to be conveyed. The side wall of the feeder body 1 is also equipped with an observation window and a feed inlet. The observation window allows the operator to check the remaining material in the storage chamber, and the feed inlet is used to replenish the storage chamber. The lower end of the base 2 is bolted to the pump body 4. The pump body 4 is a corrosion-resistant centrifugal pump. The feed end of the pump body 4 is connected to the storage chamber of the feeder body 1 through a pipe. The discharge end of the pump body 4 is connected to the feed pipe 5 through a flange. The feed pipe 5 is made of seamless steel pipe and has high strength and sealing performance. The feed pipe 5 is connected to the material conveying pipe via a connector 6, which consists of a first flange 601 and a second flange 602. Both the first flange 601 and the second flange 602 are made of forged steel to ensure structural strength. A first retaining ring 7 is welded to one end of the first flange 601 near the second flange 602. A second retaining ring 8, which mates with the first retaining ring 7, is welded to the second flange 602. The thickness and width of the first retaining ring 7 and the second retaining ring are matched to ensure a tight fit. The first retaining ring 7 has an annular groove 10 at its end. A first sealing ring 11 is glued to the inner wall of the groove 10. The first sealing ring 11 is made of oil-resistant and wear-resistant nitrile rubber, which has good sealing performance and service life. The second retaining ring 8 has an annular sealing groove 14 that matches the groove 10. The inner wall of the sealing groove 14 has an annular connecting groove 15 that matches the first sealing ring 11. The size of the connecting groove 15 is the same as the size of the first sealing ring 11, ensuring that the first sealing ring 11 can be completely embedded in the connecting groove 15 to form a tight seal. The first retaining ring 7 has two symmetrically distributed retaining grooves 9. The end of the second retaining ring 8 has an inclined surface 13 that mates with the retaining grooves 9. During installation, the inclined surface 13 guides the retaining grooves 9 of the first retaining ring 7 to smoothly engage with the second retaining ring 8, achieving rapid positioning. A second sealing ring 12 is installed at the end of the first retaining ring 7 near the sealing groove 14 through the groove. The second sealing ring 12 is made of silicone, which has good elasticity and sealing performance. When the first retaining ring 7 and the second retaining ring 8 are engaged, the second sealing ring 12 is squeezed between the two to form a second seal. Both the first flange 601 and the second flange 602 have eight mounting screw holes 16 that are evenly spaced in the circumference. The size of the mounting screw holes 16 matches that of standard bolts. During installation, bolts are passed through the mounting screw holes 16 to fasten the first flange 601 and the second flange 602 together. The number and distribution of bolts ensure that the flanges are subjected to uniform force and avoid deformation.

[0015] In use, this invention uses support legs 3 to stably place the device in the production area, and adds material into the storage chamber through the feed inlet of the main body 1 of the feeder. When material needs to be conveyed, the pump body 4 is started, and the pump body 4 draws the material in the main body 1 of the feeder into the feed pipe 5. When installing the connecting piece 6, the first flange 601 is welded and fixed to the feed pipe 5, and the second flange 602 is welded and fixed to the material conveying pipe. Then, the first retaining ring 7 and the second retaining ring 8 are aligned, and the retaining groove 9 is engaged and positioned using the inclined surface 13, so that the groove 10 fits with the sealing groove 14. The first sealing ring 11 is embedded in the connecting groove 15, and the second sealing ring 12 is compressed to form a double seal. Finally, the flange is tightened with bolts through the mounting screw holes 16. Under the action of the pump body 4, the material is conveyed to the subsequent equipment through the feed pipe 5, the connecting piece 6, and the material conveying pipe. The operator can check the remaining material through the observation window and replenish the material in a timely manner.
