In the combustion furnace, the fuel reacts chemically with oxygen to generate heat energy. The fuel can be various types of fuels, such as coal, natural gas, oil, wood, etc.

[0003] After the combustion furnace is set up, it is usually necessary to set up an oil storage tank in order to provide fuel supply for the combustion furnace and ensure the normal operation of the combustion furnace. However, the current method still has some shortcomings: the fuel in the oil tank usually needs to be filtered before being supplied to the combustion furnace to ensure the quality and purity of the fuel, thereby improving the combustion efficiency and reducing the risk of failure of the combustion furnace. At present, a filter interface can be set up at the input end of the oil pump to filter the fuel. However, after the filter interface has been used for a period of time, the residue will block the filter screen, resulting in a decrease in flow rate and reduced filtration efficiency. The filter screen also needs to be manually stopped and replaced at a fixed time, which reduces the working efficiency of the combustion furnace.

The filter ring removal device is used to remove the filter ring 106, and the oil outlet end of the oil pump 5 is connected to the oil inlet end of the combustion furnace 2 through the oil delivery pipe 6; in the above structure, the fuel oil transported between the oil storage tank 1 and the oil pump 5 is filtered by setting a filter module 10 including multiple filter rings 106, thereby ensuring the quality and purity of the fuel, and the filter ring removal device provided on the filter module 10 is used to quickly replace the filter ring 106 corresponding to the blocked filter screen 108, thereby solving the problem of reduced flow and low filtering efficiency caused by the blocked filter screen 108, without manual timed shutdown for replacement, thereby extending the maintenance cycle of the filter structure and improving the working efficiency of the combustion furnace;

[0030] like Figure 2-6 As shown, the specific structure of the filter module 10 is as follows: the filter module 10 includes a collection box 101, the top of the collection box 101 is fixedly connected to a mounting shell 102, the interior of the mounting shell 102 is rotatably connected to a gear ring 104, a plurality of mounting holes uniformly distributed circumferentially on the plate surface of the gear ring 104 are all clamped with filter collars 106, a motor 103 is fixedly installed on one side of the mounting shell 102, and one end of the output shaft of the motor 103 is fixedly connected to a driving gear 109, the driving gear 109 is located inside the mounting shell 102 and meshed with the gear ring 104, one end of the oil outlet pipe 3 is plugged into the interior of the oil storage tank 1, and the other end of the oil outlet pipe 3 is plugged into the interior of the mounting shell 102 and communicated with one end of the filter collar 106, one end of the oil extraction pipe 4 is connected to the oil extraction end of the oil pump 5, and the other end of the oil extraction pipe 4 is plugged into the interior of the mounting shell 102 and communicated with the other end of the filter collar 106;

[0031] The fuel will enter the filter module 10 through the oil outlet pipe 3 for filtration, and then enter the oil extraction pipe 4. The specific working process of the filter module 10 is as follows: Figure 3 As shown: the fuel enters the corresponding filter collar 106 through the oil outlet pipe 3, and is then filtered by the filter screen 108 in the filter collar 106, and then enters the oil extraction pipe 4;

[0032] After the filter 108 has been used for a period of time, the residue will block the filter 108, resulting in a decrease in flow rate and reduced filtering efficiency. At this time, it needs to be replaced. First, the one-way valve 31 is temporarily closed, and then the oil pump 5 and the combustion furnace 2 are stopped. Then, the motor 103 drives the driving gear 109 to rotate, and the driving gear 109 is meshed with the gear ring 104, so that the gear ring 104 drives the filter ring 106 to rotate, so that another filter ring 106 can be switched to perform filtering work, and production can be resumed. The filter ring 106 that needs to be replaced will be located at Figure 5 The position shown is convenient for personnel to replace, and the oil pump 5 can continue to operate while the filter module 10 is replaced with a new filter collar 106, thereby shortening the downtime of the combustion furnace 2 and improving production efficiency.

[0033] In order to facilitate the rapid removal of the replaced filter collar 106 , a filter collar removal device corresponding to and coaxially arranged with one of the filter collars 106 is installed on one side of the top of the collection box 101 .

[0034] like Figure 4-5 As shown, the specific structure of the filter collar removal device is as follows: the filter collar removal device includes an electric push rod 105, and an electromagnet is fixedly installed at the telescopic end of the electric push rod 105, such as Figure 7 As shown, an iron retaining ring 107 is fixedly connected to the inside of the filter ring 106 on the same side as the electromagnet, and the electromagnet is in contact with the outer side of the iron retaining ring 107 and is magnetically connected to the iron retaining ring 107.

[0035] Among them, the oil pipeline 6 is provided with a regulating valve 7 and a pressure transmitter 8, and the regulating valve 7 is electrically connected to the pressure transmitter 8; specifically, the outer wall of the oil pipeline 6 is provided with a diversion interface 9, and the diversion interface 9 is located on one side of the pressure transmitter 8; specifically, a one-way valve 31 is installed at one end of the oil outlet pipe 3, and the one-way valve 31 is electrically connected to the oil pump 5; specifically, a liquid level gauge 11 is installed inside the oil storage tank 1, and a control panel 12 is fixedly installed on one side of the oil storage tank 1, and the combustion furnace 2 and the liquid level gauge 11 are both electrically connected to the control panel 12.

[0036] In this embodiment, the flow diversion interface 9 can be externally connected to other pipelines to supply fuel to other combustion furnaces 2 .

[0037] When the electromagnet and the iron retaining ring 107 are in contact with each other through the extension of the electric push rod 105, the electromagnet will be magnetically connected to the iron retaining ring 107, and the electric push rod 105 will continue to extend, at which time it will drive the filter ring 106 to disengage from the gear ring 104. Under the connection between the electromagnet and the iron retaining ring 107, the filter ring 106 will not fall off. The upper end surface of the collection box 101 is provided with a collection port located outside the mounting shell 102. When the filter ring 106 is located above the collection port opening of the collection box 101, the electromagnet releases the adsorption of the iron retaining ring 107 at this time, and the filter ring 106 will fall into the collection box 101 for collection. A new filter ring 106 is installed at one end of the electromagnet, and then the electromagnet is turned on to adsorb the iron retaining ring 107. The cooperation of the electromagnet and the iron retaining ring 107 in this mechanism not only plays a role in limiting the filter ring 106, but also facilitates the manual installation of a new filter ring 106.

[0038] A liquid level gauge 11 is installed inside the oil storage tank 1, and a control panel 12 is fixedly installed on one side of the oil storage tank 1. The combustion furnace 2 and the liquid level gauge 11 are electrically connected to the control panel 12. The liquid level gauge 11 transmits the monitored data to the control panel 12 in real time, so that the production site can timely and accurately estimate and judge the fuel inventory and accurately arrange the production plan. In addition, the control panel 12 initiates an oil supply signal to the oil pump 5, that is, the oil pump 5 is turned on, and the fuel in the oil storage tank 1 is output to the combustion furnace 2 through the connection between the oil extraction pipe 4 and the oil outlet pipe 3, using the oil pipeline 6, to provide fuel for the combustion furnace 2. When the oil pump 5 receives the start signal, the combustion furnace 2 is also started, and when the oil pump 5 receives the shutdown signal, the combustion furnace 2 will also stop, thereby achieving the purpose of remote operation.

[0039] like Figure 4 , 7 As shown, the specific structure of the filter collar 106 is as follows: the filter collar 106 includes equal diameter sections at both ends and a large diameter section located between the equal diameter sections, the diameter of the equal diameter section is smaller than the diameter of the large diameter section, and the two ends of the large diameter section are connected to the equal diameter section through an arc transition, the filter screen 108 is fixed to the large diameter section, and the middle part of the large diameter section of the filter collar 106 is clamped in the clamping hole inside the filter module 10.

[0040] Specific working method: the control panel 12 initiates an oil supply signal to the oil pump 5, that is, the oil pump 5 is turned on, and the fuel in the oil storage tank 1 is output to the combustion furnace 2 through the connection between the oil extraction pipe 4 and the oil outlet pipe 3, and the oil delivery pipe 6 is used to provide fuel for the combustion furnace 2. When the oil pump 5 receives the start signal, the combustion furnace 2 is also started. Similarly, when the oil pump 5 receives the shutdown signal, the combustion furnace 2 will also stop. In the above process, the fuel will enter the filter module 10 through the oil outlet pipe 3 for filtration, and then enter the oil extraction The filter module 10 has a specific working process: the fuel enters the filter ring 106 through the oil outlet pipe 3, and is then filtered by the filter screen 108, and then enters the oil extraction pipe 4; after the filter screen 108 has been used for a period of time, the residue will block the filter screen 108, resulting in a decrease in flow rate and reduced filtering efficiency. At this time, it needs to be replaced, and the driving gear 109 is driven to rotate by the motor 103, and the meshing of the driving gear 109 and the gear ring 104 is utilized, so that the gear ring 104 drives the filter ring 106 to rotate. When the electromagnet contacts the iron retaining ring 107 through the extension of the electric push rod 105, the electromagnet will be magnetically connected to the iron retaining ring 107, and the electric push rod 105 will continue to extend, which will drive the filter ring 106 to separate from the gear ring 104. Under the connection between the electromagnet and the iron retaining ring 107, the filter ring 106 will not fall off. When the filter ring 106 is located above the opening of the collection box 101, the electromagnet will release the iron retaining ring 107. The filter collar 106 will fall into the collection box 101 for collection after being adsorbed; a new filter collar 106 is installed at one end of the electromagnet, and then the electromagnet is turned on to adsorb the iron retaining ring 107. The cooperation between the electromagnet and the iron retaining ring 107 in this mechanism not only plays a role in limiting the filter collar 106, but also facilitates the manual installation of a new filter collar 106. When replacing the new filter collar 106, the oil pump 5 can continue to operate, thereby shortening the downtime of the combustion furnace 2 and improving the production efficiency.
