Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically to a novel airlock unloading device. Background Technology

[0002] In many industrial production processes, such as grain processing, chemical industry, and building materials industry, it is often necessary to transfer materials from one container or conveying pipeline to another. During the material conveying process, it is necessary to effectively control the airflow to prevent gas backflow from interfering with the production process, while ensuring that the materials can be fed continuously, stably and uniformly.

[0003] Traditional airlock valves have many shortcomings in structural design and performance. For example, poor sealing performance easily leads to gas leakage, affecting the production environment and efficiency; the blades have poor wear resistance, resulting in a short service life under frequent opening and closing and material erosion, increasing maintenance costs; furthermore, traditional airlock valves are unable to meet the increasingly demanding production requirements of modern industry in terms of the precision of controlling material flow. Therefore, those skilled in the art have provided a novel airlock unloading device to solve the problems mentioned in the background art. Summary of the Invention

The rotor is installed in the valve body, and a valve cover is fixed to one side of the valve body by a flange and bolts. A sealing assembly is installed between the valve cover and the valve body; the sealing assembly includes a rubber sealing gasket and a metal sealing ring, with the rubber sealing gasket and metal sealing ring sequentially fitted from left to right on the central shaft at the connection between the valve body and the valve cover; an elastic sealing gasket is installed on the outer circumference of the streamlined blades, and a labyrinth sealing groove is provided on the inner wall of the valve body; the drive motor is connected to the reducer, and the output shaft of the reducer is connected to the central shaft; the upper and lower ends of the valve body are respectively provided with a feed inlet and a discharge outlet.

[0006] Furthermore, the drive motor is a variable frequency motor.

[0007] Furthermore, the number of streamlined blades is six.

[0008] Furthermore, the elastic sealing gasket is an elastic sealing gasket with a steel wire mesh.

[0009] The beneficial effects of adopting the above structure are as follows: the novel air-closing unloading device of this utility model significantly improves the sealing performance, effectively prevents gas backflow, improves the production environment, and increases production efficiency; by improving the wear resistance of the blades, the service life of the device is greatly extended and the maintenance cost is reduced.

[0014] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] See as Figure 1 —— Figure 2 As shown, this specific embodiment adopts the following technical solution: It includes a valve body 1, a rotor 2, a valve cover 3, a sealing assembly 4, a flange 5, bolts 6, a drive motor 7, a reducer 8, a feed inlet 9, a discharge outlet 10, an elastic sealing gasket 11, and a labyrinth sealing groove 12; the rotor 2 includes a central shaft 13 and several streamlined blades 14. Six streamlined blades 14 are evenly fixed on the outer periphery of the central shaft 13. The rotor 2 is installed inside the valve body 1. The valve body 1 is made of high-strength alloy material, which has good pressure resistance and corrosion resistance. Its internal space is designed to match the shape of the rotor 2, ensuring that materials can pass smoothly and gas is not easy to leak; a valve cover 3 is fixed on one side of the valve body 1 by a flange 5 and bolts 6. The valve cover 3 can be removed by disassembling the flange, which facilitates the inspection and maintenance of internal components; the six streamlined blades 14 are made of special wear-resistant alloy steel material, which has high wear resistance after surface hardening treatment. The shape of the blades is designed to be streamlined, which can reduce the resistance of materials during the conveying process, thereby improving the service life of the blades.

[0016] The streamlined blade 14 is equipped with an elastic sealing gasket 11 with a wire mesh on its outer periphery, and the inner wall of the valve body 1 is provided with a labyrinth sealing groove 12. When the rotor 2 rotates, the elastic sealing gasket 11 fits tightly against the inner wall of the valve body 1, effectively preventing gas backflow, and the labyrinth sealing groove 12 further prevents gas leakage.

[0017] A sealing assembly 4 is installed between the valve cover 3 and the valve body 1. The sealing assembly 4 includes a rubber sealing gasket 15 and a metal sealing ring 16. The rubber sealing gasket 15 and the metal sealing ring 16 are sequentially fitted from left to right on the central shaft 13 at the connection between the valve body 1 and the valve cover 3. The valve body 1 and the valve cover 3 are double-sealed by the rubber sealing gasket 15 and the metal sealing ring 16 to ensure the reliability of the sealing effect.

[0018] The drive motor 7 is connected to the reducer 8, and the output shaft of the reducer 8 is connected to the central shaft 13. The drive motor 7 is a variable frequency motor, which can precisely adjust the speed according to production needs, thereby achieving precise control of material flow. The reducer can increase torque to ensure that the rotor 2 can rotate smoothly and powerfully.

[0019] When this utility model is working, the upper and lower ends of the valve body 1 are respectively provided with a feed port 9 and a discharge port 10. The material enters the valve body 1 from the feed port 9, and the drive motor 7 and the reducer 8 drive the streamlined blades 14 of the rotor 2 to rotate, conveying the material to the discharge port 10.

[0020] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
