Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve technology, and in particular to a dustproof and energy-saving electromagnetic pulse valve. Background Technology

[0002] The electromagnetic pulse valve is the compressed air "switch" in the pulse jet cleaning system of a pulse jet bag filter. Controlled by the output signal of the pulse jet controller, it cleans the filter bags row by row (chamber by chamber) by pulse jet, keeping the resistance of the dust collector within a set range to ensure the dust collector's processing capacity and dust collection efficiency. It has wide applications in industrial dust removal, environmental protection, and other fields.

[0003] A search revealed a dustproof electromagnetic pulse valve (publication number CN216742914U), comprising a valve body with flanges fixed at both ends and a solenoid valve fixed on the valve body for controlling the on / off state of the electromagnet. A partition is installed inside the valve body, and oil guide holes are provided on the valve body. Dust collection boxes are symmetrically fixed at the lower end of the valve body. The valve body also includes a valve stem slidably connected to the valve body, with a toothed rod fixed at its lower end; a first rotating shaft, bearing-connected to the partition; and a filter screen fixed inside the valve body, with a second rotating shaft bearing-connected to the filter screen. This dustproof electromagnetic pulse valve employs a self-cleaning dustproof mechanism to effectively prevent dust from entering the valve and ensuring its normal operation. Combined with a linked self-lubricating mechanism, it lubricates the valve stem, preventing wear and damage caused by repeated up-and-down movement during use, thus extending the device's service life.

[0004] Based on the aforementioned patent, by incorporating a filter screen, dust can be filtered when gas enters the valve body. Furthermore, when the valve is opened or closed, the valve stem moves, and through the transmission between the toothed rod and the driving gear, as well as the transmission between the driving and driven gears, the second rotating shaft rotates, thus cleaning the filter screen and preventing dust adhesion, ensuring its dust-proof filtration effect. However, during installation, due to the different outer diameters of the connecting pipes, the valve body requires the use of fillers such as waterproof tape to thicken the outer diameter of the pipe during installation to achieve a matching installation. This results in excessive steps during pipe installation, affecting installation efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as slow installation speed due to mismatch between the valve body and the diameter of the connecting pipe, and the easy entry of dust into the valve body. This invention proposes a dustproof and energy-saving electromagnetic pulse valve that enables flexible connection between the valve body and pipes of different diameters, simplifies the installation process, improves the versatility and applicability of the equipment, reduces dust entry into the valve body, and maintains the fluid flow regulation power of the valve body.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A dustproof and energy-saving electromagnetic pulse valve includes a valve body, a connecting shell fixedly connected to the bottom of the valve body, air bladders fixedly connected to both the front and rear ends of the connecting shell, an electromagnet fixedly connected to the top of the valve body, fixing rings fixedly connected to the outer walls of both the left and right ends of the valve body, a plurality of screws connected to the opposite ends of the fixing rings via a transmission assembly, a moving block threadedly connected to the outer wall of the opposite ends of the screws, an extrusion plate connected to the outer wall of the moving block via an extrusion assembly, fixing pipes fixedly connected to both the left and right ends of the valve body, air bladders fixedly connected to the inner walls of the fixing pipes, a circulating fan installed at the top of the inner wall of the connecting shell, and fixing frames fixedly connected to both the left and right ends of the connecting shell.

[0008] Furthermore, a magnetic column is slidably connected to the top of the inner wall of the valve body, and a traction plate is rotatably connected to both ends of the magnetic column. A filter screen is rotatably connected to the opposite end of each traction plate, and the opposite end of each filter screen is rotatably connected to the left and right ends of the inner wall of the valve body.

[0009] Furthermore, the transmission assembly includes an adjusting ring rotatably connected to one end opposite to the fixed ring, an internal gear ring fixedly connected to the inner wall of each adjusting ring, and a transmission gear fixedly connected to one end opposite to the screw. The internal gear ring and the transmission gear are meshed together.

[0010] Furthermore, the extrusion assembly includes a support plate 1 that is rotatably connected to the opposite end of the moving block, and the opposite end of the extrusion plate is rotatably connected to the opposite end of the support plate 1.

[0011] Furthermore, each of the extrusion plates is rotatably connected to a second support plate at one of its opposite ends, and the opposite ends of the second support plates are rotatably connected to the inner wall of the fixed ring. Both the left and right ends of the inner wall of the valve body are fixedly connected to sealing rings.

[0012] Furthermore, the inner wall of the fixed frame is rotatably connected to both the front and rear ends with closed plates, and a return spring is fixedly connected to one end of each closed plate opposite to the other end. The other end of each return spring is fixedly connected to the front and rear ends of the fixed frame respectively.

[0013] Furthermore, air tubes are fixedly connected to both ends of the connecting shell, and the opposite ends of the air tubes are fixedly connected to and pass through the outer wall of the airbag.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the screw rotates by rotating the adjusting ring to drive the internal gear ring and the transmission gear, which in turn drives the moving block to move. The extrusion plate shrinks inward under the cooperation of support plate one and support plate two, extruding the pipe and realizing the flexible docking of the valve body with pipes of different diameters. This simplifies the installation process and improves the versatility and applicability of the equipment.

[0016] 2. In this utility model, when the circulating fan is started, the closing plate opens to both sides, allowing the air pipe to pump the air filtered by the airbag into the airbag, causing the airbag to expand and block the gap between the valve body and the pipe diameter, thereby reducing dust entering the valve body and maintaining the liquid flow regulation power of the valve body. When the circulating fan stops, the reset spring pulls the closing plate to close again at the fixed frame, thereby maintaining the airbag in an expanded state. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a dustproof and energy-saving electromagnetic pulse valve, comprising a valve body 1, a connecting shell 4 fixedly connected to the bottom end of the valve body 1, air bladders 7 fixedly connected to both ends of the connecting shell 4, an electromagnet 2 fixedly connected to the top end of the valve body 1, fixing rings 3 fixedly connected to the outer walls of both the left and right ends of the valve body 1, adjusting rings 8 rotatably connected to the opposite ends of the fixing rings 3, internal gear rings 16 fixedly connected to the inner walls of the adjusting rings 8, transmission gears 17 fixedly connected to the opposite ends of the screw 21, the internal gear rings 16 and the transmission gears 17 being meshed, and moving blocks 18 threadedly connected to the outer walls of the opposite ends of the screw 21. The moving block 18 is rotatably connected to the support plate 19 at one end and the squeezing plate 20 is rotatably connected to the support plate 19 at one end. The top of the inner wall of the valve body 1 is slidably connected to a magnetic column 10. The left and right ends of the magnetic column 10 are rotatably connected to a traction plate 11. The opposite ends of the traction plate 11 are rotatably connected to a filter screen 12. The opposite ends of the filter screen 12 are rotatably connected to the left and right ends of the inner wall of the valve body 1. The opposite ends of the squeezing plate 20 are rotatably connected to a support plate 22. The opposite ends of the support plate 22 are rotatably connected to the inner wall of the fixing ring 3. The left and right ends of the inner wall of the valve body 1 are fixedly connected to a sealing ring 13.

[0026] Specifically: When the electromagnet 2 is activated and generates magnetic force, the magnetic column 10 moves inside the valve body 1 under the action of magnetic force. At the same time, the traction plate 11 drives the filter screen 12 to deflect inside the valve body 1. This deflection action allows the filter screen 12 to effectively discharge the filtered dust during the input of clean water, thereby preventing dust from mixing into the liquid to be transported and ensuring the purity and transport efficiency of the liquid. In addition, when the two ends of the valve body 1 are connected to the pipes respectively, the sealing ring 13 ensures the sealing of the connection. In order to adapt to the installation requirements of pipes of different diameters, the operator can rotate the adjusting ring 8 to drive the internal gear ring 16 to rotate. The internal gear ring 16 further drives the transmission gear 17, causing the screw 21 to rotate accordingly. The rotation of the screw 21 drives the moving block 18 to move, and with the cooperation of the support plate 19 and the support plate 22, the extrusion plate 20 shrinks inward. This shrinkage action allows the extrusion plate 20 to fit tightly against and extrude the pipe, thereby realizing the flexible connection of the valve body 1 with pipes of different diameters, simplifying the installation process and improving the versatility and applicability of the equipment.

[0027] Reference Figure 3 and Figure 5 The valve body 1 is fixedly connected to the left and right ends of the fixed pipe 6. The inner wall of the fixed pipe 6 is fixedly connected to the air bladder 7. The top of the inner wall of the connecting shell 4 is equipped with a circulating fan 14. The left and right ends of the connecting shell 4 are fixedly connected to the fixed frame 15. The front and rear ends of the inner wall of the fixed frame 15 are rotatably connected to the closing plate 9. The opposite end of the closing plate 9 is fixedly connected to the return spring 23. The other end of the return spring 23 is fixedly connected to the front and rear ends of the fixed frame 15 respectively. The left and right ends of the connecting shell 4 are fixedly connected to the air pipe 5. The opposite end of the air pipe 5 is fixedly connected to the outer wall of the air bladder 7 and passes through it.

[0028] Specifically: When the circulating fan 14 starts, its operating power causes the closing plate 9 to open to both sides. At the same time, the air pipe 5 delivers clean air filtered by the airbag 7 into the airbag 7. As air is continuously filled, the airbag 7 gradually expands. Its expansion body tightly fills the diameter gap between the valve body 1 and the pipe, effectively preventing external dust from entering the valve body 1 through the gap, thereby ensuring the stability and efficiency of the liquid flow regulation inside the valve body 1. In addition, the expansion of the airbag 7 further enhances the sealing between the valve body 1 and the pipe, reducing the risk of liquid leakage. When the circulating fan 14 stops, the return spring 23 pulls the closing plate 9 to close again under the action of elastic restoring force, so that it fits tightly against the fixed frame 15 to maintain the expanded state of the airbag 7. This design not only achieves effective dust blocking, but also optimizes the sealing performance between the valve body 1 and the pipe through the dynamic expansion and contraction function of the airbag 7, ensuring the reliability and stability of the equipment during operation.

[0029] Working principle: When the electromagnet 2 is activated and generates magnetic force, it causes the magnetic column 10 to move within the valve body 1. This causes the magnetic column 10 to pull the filter screen 12 along the valve body 1 via the traction plate 11, causing it to deflect. This allows the dust filtered by the filter screen 12 to be discharged during the input of clean water, preventing dust from affecting the liquid being transported. When both ends of the valve body 1 are connected to the pipeline and fitted with the sealing ring 13, rotating the adjusting ring 8 drives the internal gear ring 16 to rotate. This causes the internal gear ring 16 to drive the transmission gear 17, causing the screw 21 to rotate. When the screw 21 rotates, the moving block 18 moves, causing the pressing plate 20 to be positioned between the support plate 19 and the support plate 22. With the cooperation of the compression plate 20, the compression plate 20 contracts inward, thereby squeezing the pipe, so that the valve body 1 can be connected to pipes of different diameters, making it convenient to install the valve body 1. When the circulating fan 14 is started, the closing plate 9 opens to both sides, and the air pipe 5 fills the air filtered by the air bag 7 into the air bag 7, causing the air bag 7 to expand, thereby blocking the gap between the valve body 1 and the pipe diameter, thereby reducing dust entering the valve body 1 and maintaining the liquid flow regulation power of the valve body 1. When the circulating fan 14 stops, the return spring 23 pulls the closing plate 9 to close again at the fixed frame 15, thereby maintaining the inflated state of the air bag 7.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
