Description

Technical Field

[0001] The present invention relates to the technical field of coke oven single-valve detection, and particularly to a detection device for a coke oven single-valve assembly. Background Art

[0002] The coke oven single-valve is an important device specifically designed to control the pressure inside the carbonization chamber in a coking plant. Its main function is to maintain a relatively constant pressure inside the carbonization chamber by automatically adjusting the opening degree, so as to ensure good production efficiency and product quality. It mainly consists of a valve body and a tank part for pressure regulation (as Figure 6 shown). In order to improve the structural strength of the valve body, reinforcing ribs are added, and round holes are also provided on the reinforcing ribs to reduce the overall weight of the coke oven single-valve and change the stress distribution.

[0003] To ensure the precise control of the pressure inside the carbonization chamber and avoid affecting the quality and output of coke, it is necessary to detect the sealing performance of the coke oven single-valve. The detection method is usually to close the two ports of the valve body by squeezing with a sealing plate, introduce gas from one end, connect a pressure gauge to the other end, and then judge whether the sealing performance of the single-valve is qualified according to the numerical change of the pressure gauge.

[0004] However, the following problems currently exist in the process of single-valve sealing detection: when gas is filled into the single-valve, the gas pressure inside the valve body of the single-valve increases, which will exert an outward force on the sealing plate. It is difficult to ensure the sealing between the sealing plate and the valve body only through a single extrusion, and it is easy to cause a gap between the sealing plate and the valve body, which will directly affect the accuracy of the detection result. In addition, there is no additional device for fixing the single-valve. Therefore, during the process of inflating and pressurizing, the single-valve is prone to shaking, which will also affect the accuracy of the single-valve sealing performance detection.

[0013] As a preferred solution, the second limiting part includes a support plate. Support plates are fixedly mounted at the front and rear ends of the first support seat.

[0015] As a preferred solution, the driving part includes a bidirectional screw, and the upper end of the base plate is rotatably mounted with the bidirectional screw through a bearing seat, and the two fixed plates are threadedly connected to the two threaded sections of the bidirectional screw respectively, and the upper end of the base plate is fixedly mounted with a motor located on the right side of the bidirectional screw, and the output shaft of the motor is connected to the bidirectional screw through a belt transmission.

[0016] As a preferred solution, the No. 1 limiting part includes a limiting column, and two left-right symmetrical limiting columns are fixedly installed on the opposite surfaces of the two fixed plates and located on the left side of the corresponding disk, and limiting holes are opened at positions on the base corresponding to the limiting columns one by one.

Detailed implementation manners

[0031] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] As Figure 1 shown, a detection device for a single-valve component of a coke oven includes a bottom plate 10; a vertical plate 11 is fixedly installed on the upper left side of the bottom plate 10, and a detection mechanism 2 for performing a sealing detection on the single valve is provided on the bottom plate 10, and a fixing mechanism 3 for fixing the single valve is also provided on the bottom plate 10.

[0033] As Figure 1 and Figure 2 shown, the detection mechanism 2 includes a fixing plate 20. Two symmetric fixing plates 20 are slidably installed on the front and rear of the upper end of the bottom plate 10. Discs 21 are fixedly installed on the opposite surfaces of the two fixing plates 20. A through hole is provided in the middle of the disc 21. The through hole at the front end of the front disc 21 communicates with a pressure gauge 22, and the through hole at the rear end of the rear disc 21 communicates with a conveying pipe 23. A reinforcement part 24 is provided between the two discs 21, and a driving part 25 for driving the fixing plate 20 to move is provided on the bottom plate 10.

[0034] As Figure 1As shown, the fixing mechanism 3 includes a first support base 30. On the right side between the two fixing plates 20, there is a first support base 30 fixedly installed at the upper end of the bottom plate 10 for supporting the monotonic valve body part. On the right side of the first support base 30, there is a second support base 31 fixedly installed on the bottom plate 10 for supporting the monotonic valve tank part. On the vertical plate 11, there is a pressing part 32 for pressing and fixing the monotonic valve. On the bottom plate 10, there is a squeezing part 33 for pushing and aligning the monotonic valve.

[0035] As Figure 1 and Figure 2 As shown, between the fixing plate 20 and the pressing part 32, there is a first limiting part 6 for restricting the movement of the pressing part 32. Between the pressing part 32 and the squeezing part 33, there is a second limiting part 7 for restricting the movement of the squeezing part 33.

[0036] During specific operation, manually place a monotonic valve on the first support base 30 and the second support base 31. Then, the squeezing part 33 pushes the monotonic valve from right to left to move it leftward until the monotonic valve abuts against the side wall of the first support base 30, so that the monotonic valve is pushed to the corresponding position and aligned. Then, the pressing part 32 presses and fixes the monotonic valve from top to bottom. At the same time, when the pressing part 32 moves downward, it will cooperate with the squeezing part 33 through the second limiting part 7 to restrict the movement of the squeezing part 33, thereby ensuring the stability of the position of the monotonic valve.

[0037] Then, the driving part 25 drives the two fixing plates 20 to move towards the monotonic valve. The fixing plates 20 drive the discs 21 to abut against and seal the two ports of the monotonic valve body. The movement of the fixing plates 20 restricts the movement of the pressing part 32 through the cooperation of the first limiting part 6 and the pressing part 32, thereby further improving the stability of the monotonic valve.

[0038] In addition, the movement of the fixing plates 20 will also improve the sealing effect of the discs 21 on the monotonic valve through the reinforcement part 24. Then, an external air pump is connected to the delivery pipe 23 through an external pipeline. An external solenoid valve is installed on the external pipeline. The external solenoid valve controls the external pipeline to inflate the monotonic valve through the delivery pipe 23. After filling with a certain pressure of gas, the external solenoid valve closes the external pipeline to stop inflation. Then, observe whether the value on the pressure gauge 22 changes. If the value remains unchanged, it indicates that the sealing performance of the monotonic valve is qualified. Otherwise, the sealing performance of the monotonic valve is unqualified.

[0039] As Figure 1 and Figure 2As shown, the pushing part 33 includes a pushing plate 330. The pushing plate 330 is slidably installed on the upper end of the bottom plate 10 on the left and right sides and is located on the right side of the second support seat 31. A first electric push rod 331 is fixedly installed on the upper end of the bottom plate 10 and is located behind the second support seat 31. The telescopic section of the first electric push rod 331 is fixedly connected to the pushing plate 330. Two limiting plates 332 that are symmetrically arranged before and after with respect to the first support seat 30 are fixedly installed at the left end of the pushing plate 330. The limiting plates 332 slidably penetrate through the second support seat 31.

[0040] As Figure 1 , Figure 2 and Figure 3 shown, the pressing part 32 includes a base 320. The base 320 is slidably installed on the upper and lower sides of the right end of the vertical plate 11 and is located between the two discs 21. The upper right part of the base 320 is fixedly installed with a top plate 321. A lower pressing plate 322 is fixedly installed at the position corresponding to the first support seat 30 at the lower end of the top plate 321. A pushing and pulling member 5 for pushing and pulling the base 320 to move up and down is arranged on the vertical plate 11.

[0041] As Figure 1 and Figure 2 shown, the pushing and pulling member 5 includes a third electric push rod 50. The third electric push rod 50 is fixedly installed on the right end of the vertical plate 11 and is located in front of the base 320. The telescopic section of the third electric push rod 50 is fixedly installed with a connecting plate 51. The connecting plate 51 is fixedly connected to the upper end of the base 320.

[0042] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the second limiting part 7 includes a support plate. Support plates are fixedly installed at both the front and rear ends of the first support seat 30. A T-shaped rod 70 is arranged on the support plate. The vertical section of the T-shaped rod 70 slidably penetrates through the corresponding support plate. A compression spring 71 is installed between the horizontal section of the T-shaped rod 70 and the upper end of the support plate. A through hole 72 that cooperates with the T-shaped rod 70 is opened on the limiting plate 332. The through hole 72 penetrates through the bottom plate 10 and the corresponding support plate. An extrusion assembly for pushing the T-shaped rod 70 to move downward is arranged on the lower pressing plate 322.

[0043] As Figure 1 and Figure 4 shown, the extrusion assembly includes an extrusion block 73. Extrusion blocks 73 are fixedly installed at both the left and right ends of the lower pressing plate 322 and at positions corresponding to the T-shaped rod 70.

[0044] During specific operation, the first electric push rod 331 pushes the extrusion plate 330 to move leftward. The extrusion plate 330 then pushes the monotonic valve to move leftward until the monotonic valve abuts against the first support seat 30 and is positioned correctly by the limit. Then, the third electric push rod 50 pulls the base 320 to move downward through the connecting plate 51. The base 320 then drives the lower pressing plate 322 through the top plate 321 to press and fix the valve body part of the monotonic valve.

[0045] During the downward movement of the top plate 321, it also pushes the T-shaped rod 70 to move downward through the extrusion block 73 while compressing the compression spring 71. The vertical section of the T-shaped rod 70 moves downward through the through hole 72 on the limiting plate 332 until it is inserted into the corresponding through hole 72 on the bottom plate 10, thereby restricting the movement of the extrusion plate 330 and further ensuring the extrusion stability of the extrusion plate 330 on the monotonic valve.

[0046] As Figure 1 、 Figure 2 and Figure 3 As shown in

[0047] As Figure 1 、 Figure 2 and Figure 3 As shown in

[0048] During specific operation, the motor 251 operates to drive the bidirectional screw 250 to rotate through the belt. The bidirectional screw 250 then drives the two fixing plates 20 to move synchronously towards the monotonic valve. The fixing plates 20 drive the discs 21 to fit against the end faces of the monotonic valve body to seal the two ports of the monotonic valve. During the movement of the fixing plates 20, they also drive the limit posts 60 to be inserted into the corresponding limit holes on the base 320 to restrict the movement of the lower pressing part 32, thereby ensuring the stability of the monotonic valve being squeezed and fixed.

[0049] As Figure 1 、 Figure 3 、 Figure 5 and Figure 6As shown, the reinforcement part 24 includes a cylinder 240. Cylinders 240 and insertion rods 241 arranged left and right are installed on the opposite faces of the two discs 21. The number of cylinders 240 and insertion rods 241 on the same disc 21 is two and they are arranged up and down. The cylinder 240 on one disc 21 is in plug-in fit with the insertion rod 241 on the other disc 21. A locking member 4 is provided on the base 320 and is configured to cooperate with the circular holes on the monotonic valve to limit the movement of the cylinder 240 and the corresponding insertion rod 241.

[0050] As Figure 1 , Figure 3 and Figure 5 As shown, the locking member 4 includes a second electric push rod 40. The second electric push rod 40 is fixedly installed at the right end of the base 320 and is located below the top plate 321. The telescopic section of the second electric push rod 40 slidably penetrates through the top plate 321 and then is fixedly installed with a connecting plate 41. Shaft rods 42 are fixedly installed at positions corresponding to the cylinders 240 on the two discs 21 at the lower end of the connecting plate 41. Insertion holes 43 that cooperate with the shaft rods 42 are provided on both the cylinder 240 and the insertion rod 241. The insertion holes 43 penetrate through the corresponding cylinder 240 and insertion rod 241. Circular grooves 44 are provided at positions corresponding to the shaft rods 42 on the bottom plate 10.

[0051] During specific operation, when the two fixing plates 20 approach each other, they will drive the corresponding cylinder 240 and insertion rod 241 to move until the insertion rod 241 is inserted into the corresponding cylinder 240. At the same time, the disc 21 is in close contact and sealed with the monotonic valve. Then, the second electric push rod 40 pulls the connecting plate 41 to move downward. The connecting plate 41 drives the shaft rod 42 to first penetrate through the insertion holes 43 of the corresponding cylinder 240 and insertion rod 241 located above the monotonic valve, then pass through the corresponding circular holes on the monotonic valve, and then the shaft rod 42 penetrates through the insertion holes 43 of the corresponding cylinder 240 and insertion rod 241 located below the monotonic valve and reaches the corresponding circular grooves 44 to limit the movement of the cylinder 240 and the insertion rod 241, thereby ensuring the close contact degree between the disc 21 and the monotonic valve, and further ensuring the accuracy of the sealing performance detection of the monotonic valve.

[0052] After the detection is completed, the locking member 4 releases the restriction on the cylinder 240 and the insertion rod 241. Then, the motor 251 drives the bidirectional screw rod 250 to rotate in the reverse direction to drive the corresponding disc 21 away from the monotonic valve through the fixing plate 20, and at the same time drives the limiting column 60 to disengage from the limiting hole. Then, the pressing part 32 moves upward away from the monotonic valve, and at the same time the T-shaped rod 70 releases the limit on the pushing plate 330. Then, the pushing part 33 releases the extrusion on the monotonic valve. Then, the monotonic valve is replaced, and the above operations are repeated to continue the sealing performance detection of the monotonic valve.

[0053] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself; in the description of the present invention, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0054] In the description of the present invention, it should also be noted that unless otherwise clearly specified and defined, the terms "arranged", "connected", "installed", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0055] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
