Description

Technical Field

[0001] The present invention belongs to the technical field of organic waste gas heat storage incineration devices, and in particular relates to a rotary valve body stepping operation device, and also relates to an operation method of the rotary valve body. Background Art

[0002] The valve core of the existing rotary valve RTO is directly driven by a reducer with a motor, and its operation is at a constant speed. In this mode, the pressure of the gas changes smoothly during switching, but there will be low-efficiency and high-efficiency areas during its operation. Since the valve rotates at a constant speed, the ratio of time consumed by the low-efficiency area and the high-efficiency area is fixed. Therefore, the average efficiency of the equipment during operation will be lowered due to the existence of the low-efficiency area. The longer the low-efficiency area exists, the lower the average efficiency will be. Summary of the Invention

[0003] The first object of the present invention is to provide a rotary valve stepping operation device, which solves the problem of the existing rotary valve body having a low efficiency zone that exists for a long time during operation, thereby reducing the overall efficiency.

[0004] A second object of the present invention is to provide a method for operating the rotary valve body.

[0005] The first technical solution adopted by the present invention is a rotary valve body stepping operation device, which includes an outer chamber, an air outlet box connected to the center of the lower end of the outer chamber, a rotary valve body rotatably provided at the center of the inner part of the outer chamber, an intermittent control component on the air outlet box, and the rotation of the rotary valve body is controlled by the intermittent control component; a time delay relay is also provided on the outer chamber, and the time delay relay is electrically connected to the intermittent control component.

[0006] The present invention is also characterized in that: The intermittent control component includes a cylinder rear support provided on the air outlet box, a cylinder is hinged on the cylinder rear support, a working end of the cylinder is connected to a spherical bearing, an end of the spherical bearing away from the cylinder is rotatably connected to a swing arm, an end of the swing arm away from the spherical bearing is connected to a one-way bearing, an end face of the one-way bearing away from the air outlet box is connected to a positioning gear plate, an end face of the one-way bearing close to the air outlet box is connected to a seat bearing, the seat bearing is provided on the air outlet box, an end of the seat bearing away from the one-way bearing is connected to a valve body connecting shaft, and an end of the valve body connecting shaft away from the seat bearing is connected to the rotary valve body; The air outlet box is also provided with a probe which matches the positioning gear disc.

[0007] The joint bearing and the swing arm are connected by a connecting shaft.

[0008] Twelve rectangular teeth are equidistantly arranged on the outside of the positioning toothed disc, each rectangular tooth is provided with a sensing element matched with the probe, and one of the rectangular teeth is provided with a purge area.

[0009] The cylinder is provided with a solenoid valve, which is electrically connected to the probe and the time delay relay respectively.

[0010] The probe is fixed on the air outlet box through a bracket.

[0011] The connecting shaft and the rotary valve body are connected by bolts.

[0012] The second technical solution adopted by the present invention is a method for operating a rotary valve body, using a rotary valve body stepping operation device, and the specific method is as follows: After the equipment is powered on, a signal is given to the solenoid valve, and the solenoid valve ventilation control cylinder extends to push the swing arm outward. The swing arm transmits torque to the one-way bearing, and the one-way bearing drives the rotary valve body to rotate a certain angle through the valve body connecting shaft; When the probe detects the next tooth position sensor, it gives a solenoid valve signal. The solenoid valve exhausts the air to retract the cylinder push rod to the minimum position of the cylinder extension. Since the one-way bearing transmits one-way torque, the valve body connecting shaft remains stationary when the cylinder is pulled back. When the probe detects the signal, the delay relay starts timing. After the delay timing ends, the delay relay gives the solenoid valve signal, and the cylinder is pushed out again, pushing the swing arm to control the rotary valve body to rotate a certain angle until the probe detects the sensor on the next rectangular tooth on the gear disk. The probe sends a signal to the solenoid valve, and the solenoid valve exhaust controls the cylinder to retract and pull back the swing arm. At the same time, the delay relay starts timing, and the above actions are repeated to achieve intermittent periodic motion of the rotary valve body.

[0013] The present invention is also characterized in that: The solenoid valve ventilation controls the extension and extension of the cylinder push rod, which takes 2 seconds. When the cylinder retracts and retracts, the speed can be adjusted by the exhaust volume, and the fastest speed can reach 2 seconds. The total time for retraction and delay is 8 seconds.

[0014] The beneficial effects of the present invention are: The rotary valve body stepping operation device of the present invention drives the rotary valve to rotate through multiple cylinders during the rotation of the rotary valve, and controls the valve body to form intermittent motion during the rotation process. The initial rotation cycle of the rotary valve is: 120 seconds / revolution. The furnace body is divided into 12 partitions, and the rated time required for each rotation of a zone is 10 seconds. By controlling the working speed and working frequency of the cylinder, the occupancy time of the low-efficiency zone is made 1 / 4 of the original time. It takes about 2 seconds to push each zone, and the remaining 8 seconds is in a high-efficiency state, thereby improving the operating efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Rotary valve body stepping operation device, such as Figure 1 As shown, it includes an outer chamber 14, an air outlet box is connected to the center of the lower end of the outer chamber 14, a rotary valve body 11 is rotatably provided at the center of the inner part of the outer chamber 14, an intermittent control component is provided on the air outlet box, and the rotation of the rotary valve body 11 is controlled by the intermittent control component; a time delay relay 13 is also provided on the outer chamber 14, and the time delay relay 13 is electrically connected to the intermittent control component.

[0018] like Figure 2 As shown, the intermittent control assembly includes a cylinder rear support 1 mounted on the air outlet box. A cylinder 2 is hingedly mounted on the cylinder rear support 1. The working end of the cylinder 2 is connected to a spherical bearing 3 (fisheye joint). The end of the spherical bearing 3 away from the cylinder 2 is rotatably connected to a swing arm 4. Specifically, the spherical bearing 3 and the swing arm 4 are connected by a connecting shaft 5. The end of the swing arm 4 away from the spherical bearing 3 is connected to a one-way bearing 8. The one-way bearing 8 ensures that when the cylinder 2 pushes the swing arm 4 forward, it can drive the rotary valve body 11 to rotate. However, when the cylinder 2 pulls back, the valve body connecting shaft 10 remains stationary. The end of the one-way bearing 8 away from the air outlet box is connected to a positioning gear 7. The end of the one-way bearing 8 near the air outlet box is connected to a seated bearing 9. The seated bearing 9 is mounted on the air outlet box. The end of the seated bearing 9 away from the one-way bearing 8 is connected to a valve body connecting shaft 10. The end of the valve body connecting shaft 10 away from the seated bearing 9 is connected to the rotary valve body 11. The connecting shaft 10 and the rotary valve body 11 are connected by bolts.

[0019] The air outlet box is also provided with a probe 6 that matches the positioning gear disc 7. The probe 6 is fixed to the air outlet box through a bracket.

[0020] like Figure 3As shown, 12 rectangular teeth are equidistantly provided on the outside of the positioning toothed disc 7, each of which is provided with a sensing element 15 that cooperates with the probe 6, and one of the rectangular teeth is provided with a purge area mark (corresponding to the purge area of the valve body).

[0021] The cylinder 2 is provided with a solenoid valve 12 , which is electrically connected to the probe 6 and the time delay relay 13 .

[0022] like Figure 4 As shown in , when the ventilation areas are completely overlapped, it is in a high efficiency state, and the equipment operates at the highest efficiency; Figure 5 As shown, when the ventilation area and the partition partition partially overlap, it is in an inefficient state, and the equipment operation efficiency does not reach the highest state.

[0023] The operation method of the rotary valve body uses a rotary valve body stepping operation device. The specific method is as follows: After the equipment is powered on, a signal is given to the solenoid valve 12. The solenoid valve 12 vents and controls the cylinder 2 to extend and push the swing arm 4 outward. The swing arm 4 transmits torque to the one-way bearing 8. The one-way bearing 8 drives the rotary valve body 11 to rotate a certain angle through the valve body connecting shaft 10. When the probe 6 detects the next tooth position sensor 15, it gives a signal to the solenoid valve 12. The solenoid valve 12 exhausts the air to retract the push rod of the cylinder 2 to the minimum position of the cylinder extension. Since the one-way bearing 8 transmits one-way torque, the valve body connecting shaft 10 remains stationary when the cylinder 2 is pulled back. When the probe 6 detects the signal, the delay relay 13 starts timing. After the delay timing ends, the delay relay 13 gives a signal to the solenoid valve 12, and the cylinder 2 is pushed out again, pushing the swing arm 4 to control the rotary valve body 11 to rotate a certain angle until the probe 6 detects the sensor 15 on the next rectangular tooth on the gear disk 7. The probe 6 sends a signal to the solenoid valve 12, and the solenoid valve 12 exhausts the air to control the cylinder 2 to retract and pull back the swing arm 4. At the same time, the delay relay 13 starts timing, and the above actions are repeated to realize the intermittent periodic motion of the rotary valve body 11.

[0024] Furthermore, the solenoid valve 12 controls the extension and extension of the push rod of the cylinder 2, which takes 2 seconds. When the cylinder 2 contracts and retracts, the speed can be adjusted by the exhaust volume, and the fastest speed can reach 2 seconds. The total time for retraction and delay is 8 seconds.

The end of the swing arm 4 away from the spherical bearing 3 is connected to a one-way bearing 8. The one-way bearing 8 ensures that when the cylinder 2 pushes the swing arm 4 forward, it can drive the rotary valve body 11 to rotate. However, when the cylinder 2 pulls back, the valve body connecting shaft 10 remains stationary. The end of the one-way bearing 8 away from the air outlet box is connected to a positioning gear 7.
