Description

Technical Field

[0001] The double-gate bulk material valve involved in the present invention, in particular, relates to an anti-jamming double-gate bulk material valve applied in the field of valves. Background Art

[0002] The double-gate bulk material valve is a valve designed specifically for bulk materials (such as fly ash, dry dust, granular media). Its core features lie in the double-gate structure and wear-resistant design, and it is applicable to industrial fields such as thermal power generation, cement, and chemical industries. Through designs such as double-gate sealing, wear-resistant materials, and self-cleaning structures, the double-gate bulk material valve effectively adapts to the conveying requirements of bulk materials, especially suitable for industrial environments with high wear and easy dust accumulation. However, during the actual application of the double-gate bulk material valve, the bulk material is likely to stay in the valve cavity, resulting in problems such as jamming or leakage of the double-gate bulk material valve.

[0003] To solve the problem of bulk material retention, a certain double-gate bulk material valve in the market adopts a design of an anti-deposition structure and has a certain market share.

[0004] The specification of Chinese invention patent CN201810333501.X discloses a double-gate valve, which includes a cylinder, a valve body, a valve seat, an upper gate and a lower gate. The valve body is composed of an upper valve body, a middle valve body and a lower valve body. The cylinder is connected to the middle valve body. The front end of the piston rod of the cylinder is connected with a push handle. The upper gate is connected to the upper end of the push handle, and the lower gate is connected to the lower end of the push handle. Among them, the lower gate includes an upper gasket, an inner cylinder, an outer cylinder and a lower gasket. The upper gasket is sleeved on the upper part of the positioning shaft of the push handle; the inner cylinder is sleeved on the middle part of the positioning shaft; the outer cylinder is movably sleeved on the inner cylinder; the lower gasket is sleeved on the lower part of the positioning shaft. Due to the adoption of the above structure, when the valve is in the closed state, since the valve cavity of the valve body is always communicated with the conveying pipeline on the lower valve body, under the action of the eddy current generated in the conveying pipeline, impurity deposition in the valve cavity will not occur or is not likely to occur.

[0005] The specification of Chinese invention patent application CN201110023019.4 discloses a double gate knife gate valve, which includes a valve body and a valve seat, and also includes an upper bracket and a lower bracket, an upper gate and a lower gate, an upper air cylinder and a lower air cylinder. The upper gate, the upper bracket and the upper air cylinder cooperate to form an upper opening and closing mechanism and are connected to the upper part of the valve body. The lower gate, the lower bracket and the lower air cylinder cooperate to form a lower opening and closing mechanism and are connected to the lower part of the valve body. The upper opening and closing mechanism and the lower opening and closing mechanism are distributed on a straight line. By adopting the double gate knife gate valve, when the valve is closed, the gate is pushed out from the valve cavity of the valve body towards each other like a cylinder piston. When the medium passes through, even if solid particles remain in the valve cavity, they will be pushed back into the flow channel by the gate. Since it is a double gate, the two gates move to the center of the flow channel respectively to be completely closed. After the closing is completed, there are no gaps or dead corners in the valve cavity, making it impossible for solid particles to remain in the valve cavity.

[0006] The above technology, through the technical combination of the coordinated movement of double gates, the optimized design of the structure and the application of wear-resistant materials, effectively solves the problems of jamming or leakage that occur in the application process of double gate bulk material valves. The existing technology mainly judges the actual operating state of the double gate bulk material valve through the running sound, the shape of the valve stem, the temperature of the valve body and the fluctuation condition of the air pressure cylinder, and then repairs and maintains it. However, this manual observation method has a low repair accuracy, cannot effectively maintain it at the initial stage of abnormality, reduces the durability of the double gate bulk material valve, and the manual observation method has a low degree of intelligence, reducing the efficiency of intermittent and maintenance of the double gate bulk material valve. Summary of the Invention

The automatic monitoring of the double-gate bulk material valve can be effectively realized. While reducing the difficulty of overhaul and maintenance and promoting the maintenance efficiency, it can also detect abnormal data in time and generate corresponding feedback at the initial stage when the operating state of the valve plate 3 is abnormal, promoting the timeliness of the maintenance of the double-gate bulk material valve, avoiding the damage caused by the continuous operation of the valve plate 3, effectively promoting the durability of the double-gate bulk material valve, ensuring its continuous effectiveness in the application process, and promoting the economic benefits of the application of the double-gate bulk material valve.

[0038] Figure 1 and Figure 3 It is shown that a guide seat 11 is embedded at the upper end of the valve body 1, and the cylinder 2 is installed outside the valve body 1 through the guide seat 11. A valve rod 21 is slidably arranged at the lower end of the cylinder 2. The lower end of the valve rod 21 penetrates through the guide seat 11 and is fixedly connected to the valve plate 3. The position sensing component 4 is sleeved outside the valve rod 21.

[0039] Figure 4 - Figure 8 It is shown that the position sensing component 4 includes a cooperation sleeve 41 slidably sleeved outside the valve rod 21. Limit plates 42 are fixedly connected to both the upper and lower ends of the cooperation sleeve 41. The upper end of the upper limit plate 42 is fixedly connected to the guide seat 11, and the lower limit plate 42 is fixedly connected to the limit seat 51. Reset induction contacts 43 are fixedly connected to both the upper and lower inner walls of the cooperation sleeve 41. The cooperation of the cooperation sleeve 41 and the reset induction contacts 43 can realize the acquisition of the state data when the valve plate 3 is opened. Through the way of linking with the valve plate 3, the cooperation monitoring of it can be realized, and the reset data of the valve plate 3 can be fed back in time to ensure the effectiveness of the operation of the valve plate 3.

[0040] Figure 4 - Figure 8It is shown that an induction cavity is formed in the valve plate 3 and is located on the lower side of the valve stem 21. A linkage induction disc 7 is fixedly connected in the induction cavity. A linkage cavity is formed in the linkage induction disc 7. An upper fixed block 74 is fixedly connected to the upper inner wall of the linkage cavity. A trigger slider 71 that cooperates with the upper fixed block 74 is slidably arranged in the linkage cavity. An air hole elastic filler 72 is fixedly connected between the trigger slider 71 and the upper fixed block 74. The air hole elastic filler 72 is made of a rubber / silicone composite material with air holes. While promoting the elastic effect to isolate the trigger slider 71 and the upper fixed block 74, it can also effectively realize the circulation of the gas in the linkage cavity, realize the connection and linkage effect between the linkage cavity and the cooperative sleeve 41. Linkage trigger rods 73 are fixedly connected to the ends of the trigger slider 71 and the upper fixed block 74 that are close to each other. The cooperation between the trigger slider 71 and the linkage trigger rods 73 can effectively realize the monitoring of the closed state of the valve plate 3. Through the linkage with the position sensing component 4, the cooperative monitoring of the closed state of the valve plate 3 is realized, the closing data of the valve plate 3 can be timely fed back, the effectiveness of the operation of the valve plate 3 is ensured, and the blockage condition of the valve plate 3 can be judged according to the analysis of the closing and opening data of the valve plate 3. It can be maintained and serviced in a timely and effective manner, reducing the operation and maintenance difficulty of the valve plate 3 and its operation damage.

[0041] Figure 5 and Figure 7 It is shown that auxiliary arc blocks 5 are fixedly connected to both the left and right ends of the limit seat 51. An upper lead pipe 53 that is connected to the position sensing component 4 is fixedly connected to the upper end of the auxiliary arc block 5. A lower lead pipe 52 that is connected to the linkage cavity is fixedly connected to the lower end of the auxiliary arc block 5. Through the cooperation of the auxiliary arc block 5, the lower lead pipe 52 and the upper lead pipe 53, the position sensing component 4 and the linkage cavity realize the connection and linkage effect. The setting of the auxiliary arc block 5 can effectively realize the linkage between the position sensing component 4 and the linkage induction disc 7, perform a dual data monitoring function on the valve plate 3, and achieve an all-round monitoring effect on its operating state. While effectively ensuring the effectiveness of state monitoring and reducing the operation and maintenance difficulty, it can also maintain and service the valve plate 3 in a timely manner according to the monitored feedback data, avoid the damage caused by its continuous operation, promote the durability of the double gate valve for bulk materials, and ensure its operating effectiveness in subsequent applications.

[0042] Figure 2It is shown that the operation data monitoring unit includes an open state acquisition module, a closed state acquisition module, and a monitoring data conversion and transmission module. The input end of the open state acquisition module is signal-connected to the reset induction contact block 43. The input end of the closed state acquisition module is signal-connected to the linkage contact rod 73. The input end of the monitoring data conversion and transmission module is respectively signal-connected to the open state acquisition module and the closed state acquisition module. The output end of the monitoring data conversion and transmission module is signal-connected to the monitoring and processing unit. The cooperation of the open state acquisition module and the closed state acquisition module can effectively realize the independent monitoring function of the operation state of the double-gate bulk material valve. While promoting the intelligent level of the double-gate bulk material valve, achieving an automated monitoring effect, and reducing the subsequent operation and maintenance difficulty of the double-gate bulk material valve, it can also effectively reduce the recognition difficulty of the monitoring data, reduce the operation burden of the subsequent monitoring unit, and achieve the effectiveness of the monitoring data due to the timeliness of data feedback.

[0043] Figure 2 It is shown that the input end of the monitoring data conversion and transmission module is also connected to a process anomaly acquisition module. The input end of the process anomaly acquisition module is respectively signal-connected to the open state acquisition module, the closed state acquisition module, and the instruction execution unit. The setting of the process anomaly acquisition module can effectively verify and judge the data of the opening or closing of the valve plate 3 according to its operation state, timely obtain its abnormal data, and can make an effective process analysis of the operation anomaly. Furthermore, it can reduce the analysis difficulty of the monitoring and processing unit for the operation state of the valve plate 3, promote the efficiency of its abnormal response, effectively inhibit the persistence of the abnormal state of the valve plate 3, promote the maintenance efficiency of the valve plate 3 by technicians, while reducing its continuous damage, ensure the service life of the double-gate bulk material valve, and promote the economic benefits of the application of the double-gate bulk material valve.

[0044] Figure 1 - Figure 8 It is shown that during the application of the double-gate bulk material valve, according to the instruction data transmitted by the control button on the monitoring controller to the instruction receiving unit, the monitoring and processing unit controls the cylinder 2 through the instruction execution unit, so that it drives the valve plate 3 to move up and down in the valve body 1 through the valve stem 21. When the valve plate 3 moves down to the bottom of the valve body 1, it produces a closing effect on the valve body 1 to prevent the flow of bulk materials. When the valve plate 3 moves up to the top of the valve body 1, it produces an opening effect on the valve body 1 to release the flow of bulk materials.

[0045] When the valve plate 3 moves downward under the drive of the valve rod 21, the valve plate 3 will exert a tensile effect on the cooperative sleeve 41 through the lower limiting plate 42, causing the two reset induction contact blocks 43 to separate. And due to the increase in the volume of the cooperative sleeve 41, the gas in the linkage cavity of the linkage induction disc 7 will flow into the cooperative sleeve 41 through the connection of the lower lead pipe 52, the auxiliary arc block 5 and the upper lead pipe 53, thereby driving the trigger slider 71 to move upward, continuously exhausting and squeezing the air hole elastic packing 72. After the valve plate 3 finishes moving downward, the upward movement of the trigger slider 71 will drive the linkage contact rod 73 located thereon to abut against the linkage contact rod 73 located under the upper fixed block 74. Then, the closed state acquisition module in the operation data monitoring unit can obtain the trigger data of the linkage contact rod 73 and transmit it to the monitoring data conversion and transmission module, and then transmit it to the monitoring processing unit through the monitoring data conversion and transmission module. After the monitoring processing unit obtains the closed trigger data, it judges the effectiveness of the downward movement and closing operation state of the valve plate 3 at this time, as well as the effectiveness of the control processes of the instruction execution unit and the cylinder 2;

[0046] While the instruction execution unit controls the cylinder 2 to operate, the instruction execution unit will transmit the execution instruction data to the process anomaly acquisition module. The process anomaly acquisition module collects the data of the open state acquisition module and the closed state acquisition module, and transmits the collected and analyzed data to the monitoring processing unit through the monitoring data conversion and transmission module. The data collected by the process anomaly acquisition module in the closed instruction state of the valve plate 3 is as follows: First, the open state acquisition module transmits the trigger data of the reset induction contact block 43. After the cylinder 2 starts and drives the valve plate 3 to move downward through the valve rod 21, the open state acquisition module transmits the disconnection data of the reset induction contact block 43 to the process anomaly acquisition module. Then, after the cylinder 2 completes the process instruction, the closed state acquisition module transmits the trigger data of the linkage contact rod 73 to the process anomaly acquisition module. At this time, the process anomaly acquisition module judges that the closed instruction operation data of the valve plate 3 is normal, and then transmits the relevant data to the monitoring data conversion and transmission module. The monitoring data conversion and transmission module synchronously transmits the closed operation normal data of the process anomaly acquisition module and the trigger data transmitted by the closed state acquisition module to the monitoring processing unit, so that the monitoring processing unit can quickly judge the operation state of the valve plate 3 and the states of the cylinder 2 and the instruction execution unit in a timely manner, and controls the display through the state indication unit to display the normal operation data of the double-gate bulk material valve;

[0047] When the process anomaly acquisition module collects the data of the valve plate 3 in the closed instruction state: if the open state acquisition module continuously transmits the trigger data of the reset induction contact block 43 and does not change with the subsequent execution of the cylinder 2 instruction, it is determined that the running state of the valve plate 3 is abnormal at this time; or first, the open state acquisition module transmits the trigger data of the reset induction contact block 43. After the cylinder 2 starts and drives the valve stem 21 to move downward, the open state acquisition module transmits the disconnection data of the reset induction contact block 43 to the process anomaly acquisition module. Then, after the subsequent cylinder 2 completes the process instruction, the closed state acquisition module does not transmit the closing data of the linkage lever 73. When the process anomaly acquisition module receives the double disconnection data transmitted by the open state acquisition module and the closed state acquisition module, it is determined that the running state of the valve plate 3 is abnormal at this time; the process anomaly acquisition module transmits the abnormal data to the monitoring and processing unit through the monitoring conversion transmission module. The monitoring and processing unit re-outputs the instruction to the instruction execution unit according to the abnormal data, and the instruction execution unit acts on the cylinder 2 again to monitor the subsequent running state of the valve plate 3. After the running state of the valve plate 3 returns to normal, the monitoring and processing unit does not continue to act. When the valve plate 3 still maintains an abnormal running state subsequently, the status indication unit controls the display to display the abnormal data, showing the technical personnel that the double-gate bulk material valve is in an abnormal running state, reminding the technical personnel to maintain it, so as to ensure the application effectiveness of the subsequent double-gate bulk material valve and avoid damage to the valve plate 3 caused by continuous anomalies.

[0048] When the monitoring and processing unit receives the instruction data for controlling the opening of the valve plate 3 transmitted by the instruction receiving unit and controls the cylinder 2 to act through the instruction execution unit, and drives the valve plate 3 to move upward through the valve stem 21, the valve plate 3 drives the lower limiting plate 42 to move, exerting a squeezing effect on the cooperative sleeve 41. As the internal space of the cooperative sleeve 41 is compressed, the gas inside it continuously flows into the linkage cavity of the linkage induction disc 7 through the upper lead pipe 53, the auxiliary arc block 5, and the lower lead pipe 52, exerting a swelling effect on the air hole elastic packing 72, causing the air hole elastic packing 72 to drive the trigger slider 71 to move downward, resulting in the disconnection of the linkage lever 73. After the process of the cylinder 2 is completed, the upper and lower reset induction contact blocks 43 will generate a contact trigger, causing the open state acquisition module in the running data monitoring unit to receive the trigger instruction and transmit the trigger data to the monitoring and processing unit through the monitoring data conversion transmission module. After monitoring and obtaining the open trigger data, it is judged the effectiveness of the downward movement and closing running state of the valve plate 3 at this time, as well as the effectiveness of the control process of the instruction execution unit and the cylinder 2;

[0049] While the instruction execution unit controls the cylinder 2 to perform operations, the instruction execution unit also transmits the execution instruction data to the process anomaly acquisition module. The process anomaly acquisition module collects the data of the open state acquisition module and the closed state acquisition module, and transmits the collected and analyzed data to the monitoring processing unit through the monitoring data conversion and transmission module. When the process anomaly acquisition module collects the data of the valve plate 3 in the closed instruction state: First, the closed state acquisition module transmits the trigger data of the linkage contact rod 73. After the cylinder 2 starts and drives the valve plate 3 to move upward through the valve rod 21, the closed state acquisition module transmits the disconnection data of the linkage contact rod 73 to the process anomaly acquisition module. Then, after the cylinder 2 completes the process instruction, the open state acquisition module transmits the trigger data of the reset induction contact block 43 to the process anomaly acquisition module. At this time, the process anomaly acquisition module determines that the opening instruction operation of the valve plate 3 is normal, and transmits the relevant data to the monitoring data conversion and transmission module. The monitoring data conversion and transmission module synchronously transmits the data indicating normal opening operation of the process anomaly acquisition module and the trigger data transmitted by the open state acquisition module to the monitoring processing unit, enabling the monitoring processing unit to quickly and timely determine the operating state of the valve plate 3, as well as the states of the cylinder 2 and the instruction execution unit, and controlling the display through the status indication unit to display the data indicating normal operation of the double-gate bulk material valve;

[0050] When the process anomaly acquisition module collects the data of the valve plate 3 in the open instruction state: If the closed state acquisition module continuously transmits the trigger data of the linkage contact rod 73 and does not change with the subsequent execution of the cylinder 2 instruction, it is determined that the operating state of the valve plate 3 is abnormal at this time; or first, the closed state acquisition module transmits the trigger data of the linkage contact rod 73. After the cylinder 2 starts and drives the valve plate 3 to move upward through the valve rod 21, the closed state acquisition module transmits the disconnection data of the linkage contact rod 73 to the process anomaly acquisition module. Then, after the cylinder 2 completes the process instruction, the open state acquisition module does not transmit the closing data of the reset induction contact block 43. When the process anomaly acquisition module receives the double-disconnection data transmitted by the open state acquisition module and the closed state acquisition module, it is determined that the operating state of the valve plate 3 is abnormal at this time. The process anomaly acquisition module transmits the abnormal data to the monitoring processing unit through the monitoring conversion and transmission module. The monitoring processing unit re-outputs the instruction to the instruction execution unit according to the abnormal data, and the instruction execution unit acts on the cylinder 2 again to monitor the subsequent operating state of the valve plate 3. After the operating state of the valve plate 3 returns to normal, the monitoring processing unit does not continue to generate actions. When the valve plate 3 still maintains an abnormal operating state subsequently, the status indication unit controls the display to display the abnormal data, showing the technical personnel that the double-gate bulk material valve is in an abnormal operating state, reminding the technical personnel to maintain it, so as to ensure the application effectiveness of the subsequent double-gate bulk material valve and avoid damage to the valve plate 3 caused by continuous anomalies.

[0051] Furthermore, during the operation of the double-gate bulk material valve, it can achieve dual monitoring of its operating status, improve the intelligent level of the double-gate bulk material valve, reduce its operation and maintenance difficulty, promote the maintenance efficiency, and at the same time, when the operating status of the valve plate 3 is abnormal in the initial stage, it can detect abnormal data in time and generate a corresponding feedback, promote the timeliness of the maintenance of the double-gate bulk material valve, avoid the damage caused by the continuous operation of the valve plate 3, effectively promote the durability of the double-gate bulk material valve, ensure its continuous effectiveness during application, and promote the economic benefits of the application of the double-gate bulk material valve.

[0053] Figure 1 - Figure 8 Show a double-gate bulk material valve with anti-blocking function. The lower inner wall of the valve body 1 is embedded with an electric heating liner 61. The upper end of the electric heating liner 61 is fixedly connected with a heat-conducting arc plate 6. The output end of the monitoring and processing unit is also connected with an abnormal auxiliary unit. The output end of the abnormal auxiliary unit is signal-connected with the electric heating liner 61. The settings of the electric heating liner 61 and the abnormal auxiliary unit can, when the operating status of the valve plate 3 is abnormal, promote the fluidity of the bulk material in the double-gate bulk material valve in time by means of bottom electric heating and drying, effectively drive the bulk material adhered to the inner wall of the valve body 1 due to excessive humidity, prevent it from staying continuously on the inner wall of the valve body 1, and thus can effectively avoid the blockage of the double-gate bulk material valve, promote the operating effect of the valve plate 3, and also can provide reference data for abnormal maintenance for the technical personnel in combination with the application of the abnormal auxiliary unit, timely detect the abnormal cause, promote the operation and maintenance efficiency, and ensure the continuous effectiveness of the subsequent application of the double-gate bulk material valve.

[0054] Figure 2 Show that the input end of the monitoring and processing unit is also connected with a pressure data feedback unit. The input end of the pressure data feedback unit is signal-connected with a pressure sensor arranged on the cylinder 2. The setting of the pressure data feedback unit can, when the double-gate bulk material valve has an abnormal operation, assist the monitoring and processing unit to detect the abnormal cause, improve the intelligent application of the double-gate bulk material valve, effectively reduce the operation and maintenance difficulty of the double-gate bulk material valve, promote the efficiency of dealing with the abnormal operation of the double-gate bulk material valve, and combined with the use of the abnormal auxiliary unit, can timely and effectively perform an autonomous treatment on the blocked double-gate bulk material valve, so that the double-gate bulk material valve has an automatic anti-blocking function, promote the automatic repair function of the double-gate bulk material valve, and promote the continuous effectiveness of the application of the double-gate bulk material valve.

[0055] Figure 1 - Figure 8After the monitoring processing unit receives the data on the abnormal operating state of the valve plate 3 transmitted by the monitoring data conversion and transmission module, the monitoring processing unit, through the action of the pressure data feedback unit and the pressure sensor, collects the pressure change data generated when the cylinder 2 executes an instruction. When the monitoring processing unit collects that the change of the cylinder 2 is abnormal or there is no change, it is determined that the instruction execution unit or the cylinder 2 has an abnormal operation. Then, the status indication unit is used to control the display to show the abnormal data of the instruction execution unit or the cylinder 2, so that technicians can not only obtain the abnormal signal in time, but also effectively obtain the abnormal cause, and can take timely and effective response measures, improve the efficiency of abnormal handling, and reduce the economic loss caused by the double-gate bulk material valve.

[0056] When the monitoring processing unit collects that the pressure change of the cylinder 2 is normal, it is determined that there is an abnormality inside the valve plate 3 and the valve body 1. Then, the monitoring processing unit first transmits a control instruction to the abnormal auxiliary unit, and through the abnormal auxiliary unit, an electric current is introduced into the electric heating liner 61, so that it generates a certain amount of heat acting on the bottom end inside the valve body 1, drying the inside of the valve body 1, drying the bulk material adhered to the inner wall of the valve body 1 due to humidity, and due to its flow action with the bulk material, the driving action on the dried bulk material at this time can further avoid the condensation of the bulk material inside the valve body 1. Then, the monitoring processing unit judges the effectiveness of the action of the abnormal auxiliary unit according to the data transmitted by the monitoring data conversion and transmission module and the pressure data feedback by the pressure data feedback unit;

[0057] When the monitoring data conversion and transmission module transmits the data on the normal operating state of the valve plate 3 and the pressure data feedback unit transmits that the pressure data change of the cylinder 2 is within the execution standard range, it is determined that the action of the abnormal auxiliary unit is effective at this time. Then, the monitoring processing unit controls the display to show the data of over-wet bulk material through the status indication unit, so that technicians can process the bulk material to avoid the continuous blockage of the double-gate bulk material valve caused by continuously transmitting bulk material with too high humidity, thereby avoiding the mechanical damage of the double-gate bulk material valve;

[0058] When the monitoring data conversion and transmission module transmits the data on the abnormal operating state of the valve plate 3 and the pressure data feedback unit transmits that the pressure data change of the cylinder 2 is within the execution standard range, it is determined that the action of the abnormal auxiliary unit is ineffective at this time. Then, the monitoring processing unit controls the display to show the abnormal data of the valve plate 3 through the status indication unit, so that technicians can timely check and maintain the double-gate bulk material valve, judge the abnormal cause, and timely process the abnormality to ensure the effectiveness of the subsequent operation of the double-gate bulk material valve.

[0059] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the scope of protection is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the scope of protection of the present invention.
