Description

Technical Field

[0001] This utility model relates to the field of pulse valve technology, and in particular to an anti-clogging electromagnetic pulse valve. Background Technology

[0002] An electromagnetic pulse valve is a fast-acting, electromagnetically controlled valve specifically designed for baghouse dust collectors. It is the "heart" and "switch" of the baghouse dust collector's cleaning system, and its performance directly determines the dust collector's operating efficiency and lifespan. Upon receiving a brief electrical signal from a controller (such as a PLC or pulse controller), it instantly opens, generating a strong, high-speed airflow from pre-stored compressed air in the air tank. This airflow is injected into the filter bag, causing it to rapidly inflate and vibrate, thus shaking off the dust layer adhering to the outer surface of the filter bag, achieving the purpose of dust removal.

[0003] In applications of electromagnetic pulse valves (especially submerged electromagnetic pulse valves), their outlets are typically equipped with filters to intercept external impurities (such as dust and fibers). This prevents impurities from entering the valve body and causing malfunctions such as diaphragm jamming, orifice blockage, and seal failure, ensuring the stable operation of the dust removal system. For submerged electromagnetic pulse valves, the outlet is directly connected to the dust-laden space, such as the dust collector housing. The housing maintains a high dust concentration for a long time, and a slight negative pressure environment may be formed when the valve is closed. When the filter is removed for cleaning, the outlet is directly exposed to the dust-laden space after losing the filter's obstruction. High-concentration dust will flow back into the valve body under negative pressure or airflow disturbance. This dust easily adheres to the diaphragm sealing surface, the back pressure chamber relief hole, and the orifice, causing a decrease in the sealing fit between the diaphragm and the valve seat, leading to leakage during pulse jetting or incomplete closure. Furthermore, it causes blockage of the relief hole and orifice, disrupting the internal pressure balance of the valve body. Utility Model Content

[0004] Therefore, it is necessary to provide an anti-clogging electromagnetic pulse valve that prevents dust from entering the valve body during filter cleaning, in order to address the above-mentioned technical problems.

[0005] The anti-clogging electromagnetic pulse valve provided by this utility model includes a valve body and an air inlet and an air outlet formed on the valve body, and further includes: A fixing plate is fixedly installed on one side of the valve body; A transverse groove is movably opened through the fixed plate and communicates with the air outlet. A slot is formed on the fixed plate, located below the horizontal slot, and communicates with the air outlet; The filter plate is movably installed in the transverse groove and is movably connected to the air outlet. A baffle is movably installed inside the slot and is movably connected to the air outlet. An opening and closing assembly is provided on the fixed plate and is used to drive the filter plate and the baffle to move laterally.

[0006] In one embodiment, the opening and closing assembly includes a movable groove and a moving groove, which are respectively formed on the inner wall of the bottom of the transverse groove and the inner wall of the top of the groove opening. A movable rod and a moving rod are respectively movably arranged in the movable groove and the moving groove, and one end of the movable rod and the moving rod are respectively fixedly connected to the bottom of the filter plate and the top of the baffle.

[0007] In one embodiment, the fixed plate has a groove between the transverse groove and the slot opening. The groove is connected to the movable groove and the moving groove. A cylinder is rotatably arranged in the groove. A curved groove is formed on the surface of the cylinder. The ends of the movable rod and the moving rod away from the filter plate and the baffle are slidably fitted with the curved groove.

[0008] In one embodiment, a rotating rod is fixedly provided on one side of the cylinder, and the end of the rotating rod away from the cylinder moves through the inner wall of the groove, with a rotating handle fixedly sleeved at the end.

[0009] In one embodiment, the fixing plate has vertical grooves on both the upper and lower sides of the slot, and a partition is movably arranged in the vertical groove. The partition is fixedly connected to the inner wall of the vertical groove by multiple springs. The partitions have inclined grooves at one end close to each other, and one end of the baffle is movably abutting against the inclined groove.

[0010] In one embodiment, a cleaning port is provided on the surface of the fixing plate above the transverse groove, the cleaning port is interconnected with the transverse groove, and a cover plate is movably hinged to the cleaning port.

[0011] In one embodiment, the surface of the fixing plate is provided with a receiving groove, the receiving groove is located on one side of the cleaning port, and an indicator sign is movably disposed in the receiving groove.

[0012] In one embodiment, the fixing plate has a rotating groove on one side of the transverse groove, the rotating groove is connected to the receiving groove, a rotating column is rotatably arranged in the rotating groove, and the indicator is fixedly installed on the outside of the rotating column.

[0024] The following is combined with Figures 1-7 This invention describes an anti-clogging electromagnetic pulse valve.

[0025] like Figures 1-5 As shown, in one embodiment, the anti-clogging electromagnetic pulse valve includes a valve body 1 and an air inlet 101 and an air outlet 102 formed on the valve body 1, and further includes: Fixing plate 4 is fixedly installed on one side of valve body 1; The transverse groove 41 is movably opened through the fixed plate 4 and is connected to the air outlet 102. The slot 42 is opened on the fixed plate 4, located below the horizontal slot 41, and is connected to the air outlet 102. Filter plate 2 is movably installed in the transverse groove 41 and movably connected to the air outlet 102; Baffle 3 is movably installed in slot 42 and movably connected to air outlet 102; The opening and closing assembly 5 is located on the fixed plate 4 and is used to drive the filter plate 2 and the baffle 3 to move laterally.

[0026] Specifically, during operation, filter plate 2 is located inside the air outlet 102 of valve body 1, and baffle 3 is located at the end of slot 42 away from air outlet 102. Gas enters through inlet 101 and exits through outlet 102. One end of outlet 102 is connected to the filter bag of the dust collector. The airflow through outlet 102 first passes through filter plate 2 to filter impurities before entering the filter bag, causing the filter bag to inflate and vibrate rapidly, thereby shaking off the dust layer attached to the outer surface of the filter bag, achieving the purpose of dust removal. After prolonged use, filter plate 2 needs to be cleaned regularly to remove surface dust. When the dust is removed, the filter plate 2 is moved from the outlet 102 into the transverse groove 41 by the opening and closing assembly 5. At the same time, the baffle 3 moves from the slot 42 of the fixed plate 4 into the outlet 102 to block the outlet 102, preventing dust in the dust removal equipment from entering the valve body 1 through the outlet 102 and causing blockage of the internal components of the valve body 1. The opening and closing assembly 5 can achieve the following: when the filter plate 2 is moved out of the outlet 102 for cleaning, the baffle 3 can block the outlet 102 to prevent dust from entering the valve body 1.

[0027] See Figures 3-6 As shown, in this embodiment, the opening and closing component 5 includes a movable groove 51 and a moving groove 52, which are respectively opened on the inner wall of the bottom of the transverse groove 41 and the inner wall of the top of the groove 42. A movable rod 53 and a moving rod 54 are respectively movably arranged in the movable groove 51 and the moving groove 52. One end of the movable rod 53 and the moving rod 54 are respectively fixedly connected to the bottom of the filter plate 2 and the top of the baffle 3.

[0028] Specifically, when the pulse valve is working, the filter plate 2 is located inside the air outlet 102, and the baffle 3 is located inside the slot 42, without blocking the air outlet 102. When it is necessary to clean the filter plate 2, the movable rod 53 is moved laterally along the movable slot 51 to the end away from the air outlet 102. The movable rod 53 drives the filter plate 2 to move out of the air outlet 102. At the same time, the movable rod 54 is moved along the movable slot 52 to the end closer to the air outlet 102. The movable rod 54 drives the baffle 3 to move into the air outlet 102, blocking the air outlet 102 and preventing dust from entering the valve body 1.

[0029] See Figures 2-6 As shown, in this embodiment, the fixed plate 4 is provided with a groove 43 between the horizontal groove 41 and the groove opening 42. The groove 43 is connected to the movable groove 51 and the moving groove 52. A cylinder 6 is rotatably arranged in the groove 43. A curved groove 61 is provided on the surface of the cylinder 6. The ends of the movable rod 53 and the moving rod 54 away from the filter plate 2 and the baffle 3 are slidably attached to the curved groove 61.

[0030] Specifically, when the filter plate 2 needs to be cleaned, the cylinder 6 is rotated. The rotation of the cylinder 6 in the groove 43 will drive the curved groove 61 to rotate, which will drive the movable rod 53 and the moving rod 54 to move in opposite directions, thereby realizing the reverse movement of the filter plate 2 and the baffle 3. The filter plate 2 moves out of the air outlet 102, and the baffle 3 enters the air outlet 102, preventing dust from entering the valve body 1 in the reverse direction during the maintenance and cleaning of the filter plate 2.

[0031] See Figure 4 and Figure 5 As shown, in this embodiment, a rotating rod 7 is fixedly provided on one side of the cylinder 6. The end of the rotating rod 7 away from the cylinder 6 moves through the inner wall of the groove 43, and a rotating handle 8 is fixedly sleeved at the end.

[0032] Specifically, turning the handle 8 will cause the rotating rod 7 to rotate, thereby rotating the cylinder 6. The rotation of the cylinder 6 will cause the filter plate 2 and the baffle 3 to move in opposite directions, thus blocking the air outlet 102.

[0033] See Figure 5 and Figure 6 As shown, in this embodiment, the fixing plate 4 has vertical grooves 44 on both the upper and lower sides of the groove 42. A partition 9 is movably arranged in the vertical groove 44. The partition 9 is fixedly connected to the inner wall of the vertical groove 44 by multiple springs 10. The partition 9 has an inclined groove 91 at one end close to each other. One end of the baffle 3 is movably abutting against the inclined groove 91.

[0034] Specifically, when the filter plate 2 is located inside the air outlet 102, the baffle 3 is located inside the groove 42. At this time, the two baffles 9 are in a state of close contact, which can ensure that impurities will not overflow through the groove 42 when the pulse valve is working. When the filter plate 2 needs to be cleaned, the filter plate 2 is moved out of the air outlet 102, and the baffle 3 moves into the air outlet 102. During the movement, one end of the baffle 3 will abut against the inclined groove 91, thereby pushing the two baffles 9 away from each other. The baffles 9 move towards the inside of the vertical groove 44, thereby compressing the spring 10. This will not affect the baffle 3 entering the air outlet 102. After the filter plate 2 is cleaned, the baffle 3 is moved out of the air outlet 102. When the baffle 3 is no longer in contact with the baffles 9, the two baffles 9 will be pushed out of the vertical groove 44 by the action of the spring 10 and abut against each other again to prevent dust from overflowing.

[0035] See Figure 2 and Figure 3 As shown, in this embodiment, a cleaning port 45 is provided on the surface of the fixing plate 4 above the transverse groove 41. The cleaning port 45 is connected to the transverse groove 41, and a cover plate 11 is movably hinged to the cleaning port 45.

[0036] Specifically, after the filter plate 2 is moved from the air outlet 102 into the transverse groove 41, the cover plate 11 installed at the cleaning port 45 can be opened to facilitate cleaning of the filter plate 2.

[0037] See Figure 3 and Figure 7 As shown, in this embodiment, a receiving groove 46 is provided on the surface of the fixing plate 4. The receiving groove 46 is located on one side of the cleaning port 45, and an indicator 12 is movably arranged in the receiving groove 46.

[0038] Specifically, when the filter plate 2 is inside the air outlet 102, the indicator 12 is placed horizontally in the receiving groove 46; when the filter plate 2 is removed from the air outlet 102 and needs to be cleaned, the indicator 12 is rotated 90 degrees counterclockwise, so that the indicator 12 changes from a horizontal state to a vertical state, and part of the indicator 12 is removed from the receiving groove 46, which can remind the operator that the filter plate 2 is in the process of cleaning and maintenance at this time and the pulse valve cannot be activated.

[0039] See Figure 4 and Figures 6-7 As shown, in this embodiment, the fixed plate 4 has a rotating groove 47 on one side of the horizontal groove 41. The rotating groove 47 is connected to the receiving groove 46. A rotating column 13 is rotatably arranged in the rotating groove 47. The indicator 12 is fixedly installed on the outside of the rotating column 13.

[0040] Specifically, during the process of the filter plate 2 being removed from the air outlet 102, the rotating column 13 is rotated counterclockwise. The rotation of the rotating column 13 in the rotating groove 47 will cause the indicator 12 to rotate. Part of the indicator 12 moves to the outside of the receiving groove 46 to remind the operator.

[0041] See Figure 4 and Figures 6-7 As shown, in this embodiment, the fixed plate 4 has a sliding groove 48 on the side wall of the horizontal groove 41 near the rotating groove 47. The sliding groove 48 and the rotating groove 47 are connected to each other. A limiting groove 14 is opened on the outside of the rotating column 13. A limiting rod 15 is fixedly installed on the side of the filter plate 2 near the sliding groove 48. The end of the limiting rod 15 away from the filter plate 2 slides and fits against the limiting groove 14.

[0042] Specifically, as the filter plate 2 moves from the air outlet 102 to the transverse groove 41, it will drive the limiting rod 15 to move along the sliding groove 48. One end of the limiting rod 15 moves along the limiting groove 14 opened in the rotating column 13, which will drive the rotating column 13 to rotate 90 degrees counterclockwise, so that the indicator 12 is moved out of the receiving groove 46 to remind the operator.

[0043] See Figure 7 As shown, in this embodiment, the limiting groove 14 is composed of two straight grooves 141 on both sides and an arc-shaped groove 142 in the middle, and the three are interconnected.

[0044] Specifically, as the filter plate 2 moves out of the air outlet 102, the limit rod 15 first moves along the first straight groove 141. At this time, the rotating column 13 will not rotate. Then, the limit rod 15 moves to the arc groove 142, which will drive the rotating column 13 to rotate 90 degrees counterclockwise. The indicator 12 will rotate accordingly and be in an upright position to remind the operator. Then, the limit rod 15 moves along the second straight groove 141, and the states of the rotating column 13 and the indicator 12 remain unchanged.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
