Description

Technical Field

[0001] This utility model belongs to the field of gas control technology, specifically, it relates to a DC integrated fully premixed gas controller. Background Technology

[0002] The fully premixed gas controller plays a crucial role in gas combustion equipment. The rationality of its mechanical structure directly affects the premixing effect of gas and air, the stability of the equipment, and the ease of maintenance.

[0003] In existing technologies, the mixing chamber is mostly a straight cylindrical structure, resulting in a short mixing path and little disturbance between gas and air, leading to insufficient mixing. The installation of each functional module is mostly done in a decentralized fixing method, which not only occupies a lot of space but also makes the installation and disassembly process cumbersome and difficult to maintain. The mechanical structure design of the flow regulation component is not optimized enough, and the regulation accuracy and response speed need to be improved. At the same time, the sealing and positioning accuracy between components are also insufficient, affecting the overall performance of the controller.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a DC integrated fully premixed gas controller, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A DC integrated premixed gas controller includes a DC power module, a gas regulating valve, an air flow regulating valve, a mixing chamber, an ignition module, and a central control module. The mixing chamber is characterized by having a spiral-shaped guide plate extending axially along the mixing chamber, with multiple through holes evenly distributed on the guide plate. The output ends of the gas regulating valve and the air flow regulating valve are connected to the input end of the mixing chamber via an integrated three-way flange. A sealing gasket is fitted inside the three-way flange, and a positioning pin hole is provided at its edge.

[0008] Optionally, a support frame is also provided, which has multiple sets of crossbeams that divide the support frame into upper, middle and lower layers. The surface of each crossbeam is provided with a sliding groove, and a fixing component is connected to the sliding groove.

[0009] Optionally, the fixing assembly includes a connecting plate connected to the slide groove via a slider, the DC power module and the central control module are mounted on the upper layer of the bracket via the fixing assembly and the crossbeam, and the mixing chamber and the ignition module are fixed to the lower layer of the bracket by bolts.

[0010] Optionally, a connecting ring is also connected to the surface of the connecting plate in the middle layer of the bracket. The connecting ring corresponds to the gas regulating valve and the air flow regulating valve. The gas regulating valve and the air flow regulating valve are connected to the middle layer of the bracket through the connecting ring and the fixing component.

[0011] Optionally, the output end of the mixing chamber is equipped with a detachable burner head, which is connected to the mixing chamber by a thread, and the surface of the burner head is evenly distributed with ignition holes and heat dissipation fins.

[0012] Optionally, the ignition needle of the ignition module is equipped with an adjustable mounting base, which consists of a fixed ring and an adjusting ring. The fixed ring is welded to the outer wall of the mixing chamber, and the adjusting ring is connected to the fixed ring by bolts. After the ignition needle passes through the adjusting ring, it is fixed by a lock nut.

[0013] Optionally, the bracket is further provided with reinforcing ribs, and shock-absorbing pads are connected to the bottom of the bracket.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. By setting up a guide plate, which is spiral in shape, the gas can be guided to form a spiral flow, which greatly extends the mixing path and residence time. The uniform through holes on the guide plate further enhance the gas disturbance, allowing the gas and air at different positions to fully penetrate and mix, and the mixing uniformity is significantly improved.

[0016] 2. By setting up brackets and crossbeams, the brackets are divided into three layers (upper, middle, and lower) through multiple sets of crossbeams. Combined with the crossbeam slides and the fixing components with sliders, the modules can be installed in a layered and centralized manner. The upper layer contains the DC power supply module and the central control module, the middle layer contains the gas regulating valve and the air flow regulating valve, and the lower layer contains the mixing chamber and the ignition module. The layout is clear and orderly, saving a lot of space. The cooperation between the slides and the sliders makes the module installation and disassembly convenient.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this embodiment provides a DC integrated fully premixed gas controller, including a DC power supply module 8, a gas regulating valve 7, an air flow regulating valve 11, a mixing chamber 5, an ignition module, and a central control module 9. The characteristic feature is that a spiral-shaped guide plate 15 extending axially along the mixing chamber 5 is provided inside the mixing chamber 5, and multiple through holes are evenly distributed on the guide plate 15; the output ends of the gas regulating valve 7 and the air flow regulating valve 11 are connected to the input end of the mixing chamber 5 via an integrated connecting three-way flange 6, and a sealing gasket is fitted inside the connecting three-way flange 6, with a positioning pin hole at its edge.

[0028] Inside the mixing chamber 5, a spiral-shaped guide plate 15 extending axially is installed. This guide plate 15 has a unique design; firstly, its spiral structure guides the gas and air to form a spiral flow within the mixing chamber 5, extending the residence time of the gas and promoting more thorough mixing. Secondly, multiple through holes are evenly distributed on the guide plate 15, allowing gas and air at different locations to permeate each other, further enhancing the mixing effect. Connecting components: The output ends of the gas regulating valve 7 and the air flow regulating valve 11 are connected to the input end of the mixing chamber 5 via an integrated three-way flange 6. The use of the three-way flange 6 cleverly achieves convenient connection between the gas and air pipelines and the mixing chamber 5. A sealing gasket is fitted inside the connecting three-way flange 6, effectively preventing gas and air leakage at the connection point, ensuring the system's sealing and safety. Additionally, a positioning pin is provided at the edge of the connecting three-way flange 6. The positioning pin holes are used for precise positioning during installation, ensuring the accuracy of the connection positions of each component, improving installation efficiency, and enhancing the stability of the entire connection structure. Through the synergistic effect of the spiral guide plate 15 and its through holes within the mixing chamber 5, the gas and air can achieve a more complete and uniform mixture. This provides favorable conditions for the subsequent combustion process, enabling more complete combustion of fuel, improving combustion efficiency, reducing energy waste, and lowering the emission of harmful gases (such as carbon monoxide and other incomplete combustion products). The integrated connecting tee flange 6, combined with the sealing gasket and positioning pin hole design, not only ensures the sealing of the gas and air delivery pipelines connected to the mixing chamber 5, avoiding safety hazards caused by gas leaks, but also facilitates positioning operations during installation, ensuring the accuracy and stability of the connection, reducing the probability of malfunctions due to improper installation, and improving the reliability and service life of the entire gas controller system.

[0029] In this embodiment, a support 1 is also provided. The support 1 has multiple sets of crossbeams 2, which divide the support 1 into three layers: upper, middle, and lower. The surface of the crossbeams 2 is provided with a sliding groove 13, and a fixing component is connected to the sliding groove 13. The fixing component includes a connecting plate 12 connected to the sliding groove 13 by a slider. The DC power module 8 and the central control module 9 are installed on the upper layer of the support 1 through the fixing component and the crossbeams 2. The mixing chamber 5 and the ignition module are fixed to the lower layer of the support 1 by bolts. The surface of the connecting plate 12 in the middle layer of the support 1 is also connected with a connecting ring 10. The connecting ring 10 corresponds to the gas regulating valve 7 and the air flow regulating valve 11. The gas regulating valve 7 and the air flow regulating valve 11 are connected to the middle layer of the support 1 through the connecting ring 10 and the fixing component.

[0030] The layered design makes the installation positions of each module clearer, avoids mutual interference between components, and makes the overall structural layout more reasonable and compact, saving installation space. The fixing method of the slide groove 13 and the slider makes the installation and disassembly of each module more convenient, facilitating later maintenance and replacement. At the same time, this connection method can accommodate the slight displacement of components to a certain extent, reducing the damage caused by rigid connections. The design of the middle connecting ring 10 provides a stable mounting point for the gas regulating valve 7 and the air flow regulating valve 11, ensuring their stability during operation and contributing to the smooth delivery of gas and air.

[0031] The output end of the mixing chamber 5 is equipped with a detachable burner head 16. The burner head 16 is connected to the mixing chamber 5 by a thread, and the surface of the burner head 16 is evenly distributed with ignition holes 18 and heat dissipation fins 17.

[0032] The detachable and threaded design of the burner head 16 facilitates cleaning, replacement and maintenance of the burner head 16. When the burner head 16 is damaged or blocked, it can be dealt with quickly. The evenly distributed ignition holes 18 are conducive to the uniform combustion of gas and improve combustion efficiency. The heat dissipation fins 17 can dissipate the heat generated by combustion in time, prevent the burner head 16 from being damaged due to excessive temperature and extend its service life.

[0033] The ignition needle 14 of the ignition module is equipped with an adjustable mounting base, which consists of a fixed ring 19 and an adjusting ring 20. The fixed ring 19 is welded to the outer wall of the mixing chamber 5, and the adjusting ring 20 is connected to the fixed ring 19 by bolts. The ignition needle 14 passes through the adjusting ring 20 and is fixed by a lock nut.

[0034] The adjustable mounting base can precisely adjust the angle of the ignition needle 14 according to the actual combustion conditions, ensuring that the ignition needle 14 is in the optimal ignition position, improving the success rate and reliability of ignition, and reducing the occurrence of ignition failure. The fixing ring 19 is welded to the outer wall of the mixing chamber 5 to ensure the overall stability of the mounting base. The adjusting ring 20 and the fixing ring 19 are connected by bolts and the locking nut is used to fix the ignition needle 14, so that the angle can be firmly fixed after adjustment, avoiding angle deviation during operation.

[0035] The bracket 1 is also equipped with reinforcing ribs 4, and shock-absorbing pads 3 are connected to the bottom of the bracket 1.

[0036] The reinforcing rib 4 significantly enhances the overall structural strength and rigidity of the support 1, improves the load-bearing capacity and deformation resistance of the support 1, and ensures the stability of the support 1 during long-term use. The shock-absorbing foot pad 3 can effectively absorb the vibration generated during equipment operation, reduce the impact of vibration on the connection of various components, reduce problems such as component loosening and wear caused by vibration, and at the same time reduce the noise generated during equipment operation and improve the working environment.

[0037] Working principle:

[0038] After the DC power module 8 supplies power to the entire controller system, the central control module 9 starts up and enters the working state. Under the control of the central control module 9, the gas regulating valve 7 and the air flow regulating valve 11 deliver gas and air respectively according to the set ratio. The two gases enter the mixing chamber 5 through the integrated three-way flange 6. The precise positioning and sealing design of the three-way flange 6 ensures the stability and sealing of the gas delivery.

[0039] After entering the mixing chamber 5, the gas forms a spiral flow under the guidance of the spiral guide plate 15, which prolongs the residence time. At the same time, the through holes on the guide plate 15 allow the gas and air at different positions to permeate each other, achieving full and uniform mixing. The mixed gas flows to the burner head 16 at the output end of the mixing chamber 5.

[0040] At this time, the central control module 9 instructs the ignition module to work. Under the action of the adjustable angle mounting seat, the ignition needle 14 is in the optimal ignition position, accurately igniting the gas mixture at the burner head 16. The heat generated by combustion is released through the ignition hole 18 on the surface of the burner head 16, and the heat dissipation fins 17 dissipate excess heat in time to prevent the burner head 16 from overheating.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
