Description

Technical Field

[0002] The slide gate valve constant volume metering device is a piece of equipment that combines the structure of a slide gate valve with the principle of constant volume metering to achieve quantitative material loading. It is widely used in industries such as chemical, food, building materials, and metallurgy, and is especially suitable for quantitative conveying and loading of granular, powdery, or small block materials.

[0003] In the prior art, when the slide gate valve is opened, the material enters the fixed volume metering chamber under the action of gravity or external force until the chamber is filled.

[0025] Specifically, the first saucer 1 and the second saucer 29 are placed on the weighing plate 20. The weighing sensor 12 in the weighing module 3 senses the weight of the first saucer 1 and the material through the weighing pad 11. The pad 13 and the mounting pad 14 ensure the stable installation of the weighing structure. Driven by the guide rod cylinder 17, the saucer weighing lifting mechanism 4 drives the lifting plate 10 to rise and fall smoothly through the guidance of the first guide shaft 15, the second guide shaft 19 and the linear bearing 21, realizing the lifting and positioning of the first saucer 1. The limiting plate 18 limits the maximum lifting height to ensure operational safety.

[0026] A mounting pad 14 is fixedly connected to the bottom of the pad 13, a first guide shaft 15 is fixedly connected to the bottom of the mounting pad 14, and a lifting cylinder mounting plate 16 is fixedly connected to the outside of the first guide shaft 15.

[0027] A guide rod cylinder 17 is fixedly connected to the top of the lifting cylinder mounting plate 16, and a second guide shaft 19 is rotatably connected to the bottom of the weighing pad block 11. A limit plate 18 is rotatably connected to the outside of the second guide shaft 19.

[0028] The top of the weighing pad 11 is fixedly connected to the weighing plate 20, and the bottom of the weighing plate 20 is fixedly connected to the linear bearing 21.

[0029] The bottom of the first sagger 1 is fixedly connected to a weighing module 3, and the internal thread of the slide valve assembly 2 is connected to a first internal hexagon screw 22. The bottom thread of the first internal hexagon screw 22 is connected to a brass washer 23.

[0030] The brass gasket 23 is externally fixedly connected to a slide valve fixing plate 24, and the bottom of the slide valve fixing plate 24 is fixedly connected to a spring washer 25. The bottom of the spring washer 25 is threadedly connected to a second internal hex screw 26.

[0032] Specifically, the first cam assembly 28 and the second cam assembly 32 assist in the coordinated movement of the various components during the operation of the mechanism, while the connecting parts and reinforcing structures such as the first hexagon socket screw 22, brass washer 23, spring washer 25, second hexagon socket screw 26 and reinforcing rib 27 ensure the stability and durability of the entire device.

[0033] The second sagger 29 is internally fixedly connected to an end face sealing plate 30, and externally fixedly connected to an outlet pressing assembly 31. The top of the slide valve assembly 2 is fixedly connected to multiple dropping hoppers 34, the bottom of the dropping hopper 34 is fixedly connected to a movable slide plate 33, and externally fixedly connected to a second cam assembly 32.

[0034] Specifically, after the material is conveyed to the discharge hopper 34, the slide gate valve assembly 2 becomes the key to controlling the material's descent. The slide gate valve cylinder assembly 8 drives the movable slide gate 33 to move, and the slide gate valve fixing plate 24 provides stable support for it. The opening and closing of the movable slide gate realizes the start and stop control of the material's descent. The end face sealing plate 30 and the discharge port pressing assembly 31 enhance the sealing performance of this part to prevent material leakage.

[0035] Working principle: The material is conveyed by the screw conveyor 5 under the support of the screw frame assembly 6. The screw connecting frame 7 ensures a stable connection between the conveyor and the subsequent structure, while the arch breaking mechanism 9 effectively prevents the material from arching and blocking during the conveying process, ensuring the continuity of material conveying.

[0036] After the material is conveyed to the discharge hopper 34, the slide gate valve assembly 2 becomes the key to controlling the material's descent. The slide gate valve cylinder assembly 8 drives the movable slide gate 33 to move, and the slide gate valve fixing plate 24 provides stable support for it. The opening and closing of the movable slide gate realizes the start and stop control of the material's descent. The end face sealing plate 30 and the discharge port pressing assembly 31 enhance the sealing performance of this part to prevent material leakage.

[0037] Simultaneously, the weighing system is activated. The first saucer 1 and the second saucer 29 are placed on the weighing plate 20. The weighing sensor 12 in the weighing module 3 senses the weight of the first saucer 1 and the material through the weighing pad 11. The pad 13 and mounting pad 14 ensure the stable installation of the weighing structure. Driven by the guide rod cylinder 17, the saucer weighing lifting mechanism 4, guided by the first guide shaft 15, the second guide shaft 19, and the linear bearing 21, drives the lifting plate 10 to rise and fall smoothly, achieving the lifting and positioning of the first saucer 1. The limiting plate 18 restricts the maximum lifting height to ensure operational safety.

[0038] During the loading process, the fixed-volume method uses a slide gate valve to control the time and amount of material falling to achieve preliminary quantitative loading. The real-time weight data from the weighing sensor is used for precise calibration. When the material weight reaches the set value, the slide gate valve cylinder assembly drives the movable slide gate to close, completing one quantitative loading cycle. The first cam assembly 28 and the second cam assembly 32 assist in coordinating the actions of each component during mechanism operation. Connectors and reinforcing structures such as the first hexagon socket screw 22, brass washer 23, spring washer 25, second hexagon socket screw 26, and reinforcing rib 27 ensure the stability and durability of the entire device.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
