Description

Technical Field

[0001] The utility model relates to the technical field of machinery and valves, in particular to a heavy hammer flap air-locking unloading valve device with a cam mechanism. Background Art

[0002] The heavy hammer flap air lock unloading valve is an indispensable key equipment for material delivery, smoke recovery and treatment and emission in the industrial production kiln system. It is an executive equipment that attaches equal importance to production activities and environmental protection, and has special significance for people's production and life. The electric heavy hammer flap air lock unloading valve has the characteristics of uniform unloading, random temperature change, large working temperature span, air lock and pressure maintenance, complex chemical composition of the working medium, and large demand. Therefore, the development of an electric heavy hammer flap air lock unloading valve with good working performance has always been an important topic for related valve manufacturers and users. The heavy hammer flap unloading valve in the prior art relies on the weight of the material and the balance relationship between the valve configuration heavy hammer to realize the rotation of the flap. This valve flap rotation has uncertainty, and the flap reversal process cannot achieve complete reversal and unloading. After the flap is reversed to a certain angle, the material falls, and the configured heavy hammer rotates to close the flap due to the change in the balance relationship. This method cannot achieve the timing and quantitative release of materials downward. In view of the defects of the above-mentioned prior art, it is urgently needed to design a heavy hammer flap air lock unloading valve device that can release materials downward in a timely and quantitative manner.

[0021] See attached Figure 1-2 , installation and connection of the device, two flap shafts 21 are respectively installed on the upper valve body 1, and an upper flap 22 is respectively installed on each flap shaft 21. Both flap shafts 21 extend out of the upper valve body 1, and bearing assemblies 23 are respectively installed at both ends of the flap shaft 21. The upper left weight handle 4 is fixedly installed at one end of the left flap shaft 21, the upper left weight 5 is installed at the end of the upper left weight handle 4, the upper right weight handle 20 is fixedly installed at one end of the right flap shaft 21, and the upper right weight 19 is installed at the end of the upper right weight handle 20. The other ends of the two flap shafts 21 are respectively connected to the crank connecting rod mechanism. Two flap shafts 21 are mounted on the lower valve body 14, each flap shaft 21 is respectively mounted with a lower flap 13, the two flap shafts 21 are both extended out of the lower valve body 14, the bearing assemblies 23 are respectively mounted on the two ends of the flap shaft 21, the left lower weight handle 11 is fixedly mounted on one end of the left flap shaft 21, the left lower weight 10 is mounted on the end of the left lower weight handle 11, the right lower weight handle 16 is fixedly mounted on one end of the right flap shaft 21, the right lower weight 15 is mounted on the end of the right lower weight handle 16, and the other ends of the two flap shafts 21 are respectively connected to the crank connecting rod mechanism. The machine base 26 is welded to the lower part of the lower valve body 14, the reducer 25 is mounted on the machine base 26, the output shaft of the reducer 25 is connected to the cam 7, and the upper valve body 1 and the lower valve body 14 are sealed and connected by fastening bolts.

[0022] The left upper crank 3 is mounted on the end of the flap shaft 21 on the left side of the upper valve body 1, the right upper crank 18 is mounted on the end of the flap shaft 21 on the right side of the upper valve body 1, the upper roller 6 is mounted on one end of the left upper crank 3, the upper connecting rod 2 is mounted on the other end, and the other end of the upper connecting rod 2 is connected to the right upper crank 18 mounted on the right flap shaft 21 of the upper valve body 14. The left lower crank 9 is mounted on the end of the flap shaft 21 on the left side of the lower valve body 14, the right lower crank 17 is mounted on the end of the flap shaft 21 on the right side of the lower valve body 14, the lower roller 8 is mounted on one end of the left lower crank 9, the lower connecting rod 12 is mounted on the other end, and the other end of the lower connecting rod 12 is connected to the right lower crank 17 mounted on the right flap shaft 21 of the lower valve body 14. The upper roller 6 at the end of the upper left crank 3 and the lower roller 8 at the end of the lower left crank 9 are respectively in contact with the outer contour of the cam 7, the upper left crank 3, the upper right crank 18, and the upper connecting rod 2 are respectively connected by the upper pin 24, and the lower left crank 9, the lower right crank 17, and the lower connecting rod 12 are respectively connected by the lower pin 27.

[0023] When in use, when the motor of the reducer 25 is energized, it drives the cam 7 to rotate, and the upper roller 6 at the end of the upper left crank 3 and the lower roller 8 at the end of the lower left crank 9 are in surface contact with the cam 7 respectively. The cam 7 pushes the upper left crank 3 and the lower left crank 9 to move around the cam 7 through the upper roller 6 and the lower roller 8. When the upper roller 6 or the lower roller 8 slides over the high point of the cam 7, since one end of the flap shaft 21 is provided with a weight handle and a weight, the upper flap 22 and the lower flap 13 are closed under the action of the weight, and the upper left crank 3 drives the upper flap 22 to rotate around the flap shaft 21 through the upper connecting rod 2, and the lower left crank 9 drives the lower flap 13 to rotate around the flap shaft 21 through the lower connecting rod 12, thereby converting the rotational motion of the cam 7 into the opening and closing motion of the upper flap 22 and the lower flap 13. When the upper flap 22 is in an open state, the lower flap 13 is in a closed state; when the upper flap 11 is in a closed state, the lower flap 13 is in an open state, forming a staggered opening and closing state of the upper and lower flaps.

[0024] When the material is at the upper flap 22, the upper left crank 3 is driven by the upper roller 6 to move along the outer contour of the cam 7. The upper flap 22 is opened by the rotation of the flap shaft 21, the upper left crank 3 and the upper right crank 18, and the material falls onto the lower flap 13. After the cam 7 runs over the high point, the upper flap 22 is quickly closed under the action of the upper left weight 5 and the upper right weight 19. The cam 7 continues to rotate, driving the lower flap 13 to open, and the material falls. After the cam 7 rotates over the high point, the lower flap 13 is quickly closed under the action of the lower left weight 10 and the lower right weight 15. During the entire falling process of the material, one layer of the upper flap 22 and the lower flap 13 is always closed, and the material is unloaded continuously. The pipeline is always in a closed state, meeting the requirements of air-locked unloading. The material is discharged continuously and intermittently through the rotation of the motor, which solves the problems of uneven and irregular material discharge from the heavy hammer flap valve, which causes the prolonged production cycle and increased energy consumption.

[0025] The above is only a non-limiting implementation method of the utility model, and a large number of embodiments can be derived. For ordinary technicians in this field, without departing from the creative concept of the present invention and without making creative work, several modified and improved embodiments can be made, which all fall within the scope of protection of the present invention.
