Description

Technical Field

[0001] The utility model relates to the field of discharge valves, in particular to a double-impeller heavy-sensing air-locking discharge valve structure. Background Art

[0002] The double impeller air lock discharge valve is mainly used to control the flow and discharge of materials in the material conveying system. Its main feature is that it has two rotating impellers. The two impellers work together to effectively prevent the leakage of airflow generated during the discharge process, thereby achieving the effect of air lock. This equipment is particularly useful in industrial environments where it is necessary to maintain a stable internal air pressure in the system or prevent dust from leaking out. Through the rotating impeller, the material can be discharged smoothly from the container while maintaining a stable pressure inside the system;

[0003] A Chinese patent with publication number CN206927273U discloses a double-impeller air-locking unloading valve, comprising a housing and a motor, wherein an inlet flange is arranged on the top of the housing and an outlet flange is arranged on the bottom, a driving shaft and a driven shaft are arranged inside the housing, and the two impellers are linked by externally meshing gears, wherein the blades of the small impeller just extend into the blade gap of the large impeller, so that during operation, the two impellers are always meshed and operated, and the outer end of the blade of the small impeller is a hook-shaped structure, which can clean the opposite blades of each other while continuously rotating to unload.

[0004] When the air-locking discharge valve of the above-mentioned patent rotates and transfers materials, the materials can only be transferred to the upper end between the large impeller and the small impeller, and uniform flow distribution cannot be achieved, which affects the overall operation of the equipment and causes the equipment to be unable to be used normally.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to solve the problem that when the existing air lock discharge valve rotates and transfers materials, the materials can only be transferred to the upper end between the large impeller and the small impeller, and uniform flow cannot be achieved, which affects the overall operation of the equipment and causes the equipment to be unable to be used normally, this embodiment provides the following technical solutions:

[0023] A double-impeller heavy-sensing air-locking discharge valve structure comprises a housing 1, and a material receiving frame 2 is arranged at the upper end of the housing 1.

An access panel 3 is provided on one side of the outside of the shell 1, and the access panel 3 is fixedly connected to the shell 1 by bolts. The access panel 3 is sealed and installed inside the shell 1 by bolts, and the sealing completes the air-locking unloading.

[0024] In this embodiment, both sides of the lower end of the housing 1 are provided with connecting pipes 4 for transmission. Figure 1 and Figure 4 As shown, a fan is provided at one end of the connecting pipe 4, and the output of the fan can push the granular material falling into the connecting pipe 4. A weight sensing device is provided at the lower end of the connecting pipe 4, and the weight sensing device can be used to facilitate the weight detection of the granular material transmitted by the first impeller 8 and the second impeller 9;

[0025] In this embodiment, a first impeller 8 is disposed at one end of the housing 1, and a second impeller 9 is disposed at the other end of the housing 1. Figure 2 and Figure 5 As shown, a third cylindrical gear 17 is welded to one end of the first impeller 8, and a fourth cylindrical gear 18 is welded to one end of the second impeller 9. The rotation of the fourth cylindrical gear 18 and the third cylindrical gear 17 can directly drive the first impeller 8 and the second impeller 9 to rotate, and the rotation enables the material transported by the material receiving frame 2 to contact the first impeller 8 and the second impeller 9 respectively, thereby realizing air-locking unloading;

[0026] In this embodiment, a first cylindrical gear 15 is disposed on one side of the lower end between the third cylindrical gear 17 and the fourth cylindrical gear 18, and a second cylindrical gear 16 is disposed on the other side of the lower end between the third cylindrical gear 17 and the fourth cylindrical gear 18. Figure 5 As shown, the first cylindrical gear 15, the second cylindrical gear 16, the third cylindrical gear 17 and the fourth cylindrical gear 18 are meshed and connected in sequence. Through the meshed connection, the first cylindrical gear 15 can drive the first cylindrical gear 15, the second cylindrical gear 16, the third cylindrical gear 17 and the fourth cylindrical gear 18 to rotate at the same time after the output;

[0027] In this embodiment, a second transmission rod 20 is provided at the upper end between the third cylindrical gear 17 and the fourth cylindrical gear 18, and the second transmission rod 20 is connected to one side of the outer side of the fourth cylindrical gear 18 through a second synchronous belt 19.

Through the meshing connection and the transmission of the second synchronous belt 19, the fourth column gear 18 can drive the second sector gear 22 to rotate after rotating;

[0028] In this embodiment, a first transmission rod 11 is provided at the upper end between the first impeller 8 and the second impeller 9, and the first transmission rod 11 is connected to the second sector gear 22 through a first synchronous belt 12.

[0030] In this embodiment, if Figure 2 and Figure 4 As shown, the lower ends of the first impeller 8 and the second impeller 9 are both provided with inclined guide slopes 10. The granular materials transmitted by the first impeller 8 and the second impeller 9 through rotation will be sent into the interior of the connecting pipe 4 after being guided by the guide slopes 10, so as to facilitate the transmission of the granular materials inside the connecting pipe 4.

[0031] Working principle: When the device is used and the granular material in the inspection plate 3 is unloaded in an air-locking manner, the granular material is placed in advance inside the material receiving frame 2. Due to its own weight, the granular material is transmitted through the hose 5 and from the guide ring 13. The output of the motor corresponding to the first cylindrical gear 15 is started. The rotation of the first cylindrical gear 15 can simultaneously drive the second cylindrical gear 16 and the fourth cylindrical gear 18 to rotate. The rotation of the second cylindrical gear 16 can drive the third cylindrical gear 17 to rotate. The rotation of the third cylindrical gear 17 and the fourth cylindrical gear 18 can drive the corresponding first impeller 8 and the second impeller 9 to rotate. The rotation completes the air-locking unloading of the granular material. At the same time, the fourth cylindrical gear 18 drives the second transmission rod 20 to rotate through the second synchronous belt 19. The rotation of the second transmission rod 20 can drive the first sector gear 21 at the corresponding end to rotate, and the first sector gear 21 can drive the second sector gear 22 to rotate through meshing connection, and the second sector gear 22 can drive the first transmission rod 11 to rotate through the first synchronous belt 12. The rotation of the first transmission rod 11 can drive the guide ring 13 at one end to rotate, and the guide ring 13 will drive the upper end of the hose 5 to rotate around the first transmission rod 11 through the connecting ring 14, so that the granular material transmitted by the hose 5 is accurately transmitted to the upper ends of the first impeller 8 and the second impeller 9 respectively, and the first impeller 8 and the second impeller 9 rotate to drive the granular material to move toward the connecting pipe 4 at a uniform speed. During the movement, it will be restricted by the guide slope 10 and transmitted to the inside of the connecting pipe 4 after diversion.
