Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a feeding mechanism for a catalytic combustion machine. Background Art

[0002] A catalytic burner, or catalytic combustion equipment, is a device or equipment that performs combustion under the action of a catalyst. It utilizes a catalyst at a relatively low ignition temperature to cause flameless combustion of organic waste gas, thereby decomposing it into non-toxic carbon dioxide and water vapor, thereby purifying the waste gas. Organic waste gas produced by some processes may contain a certain amount of solid waste, which requires filtration before entering the catalytic burner to prevent the solid waste from entering the machine and affecting the catalytic combustion reaction or contaminating the catalyst.

[0003] A common way to filter solid matter in exhaust gas is to set up a filter structure, which intercepts solid particles through tiny holes to play a filtering role. However, after long-term use, the filter structure will cause a large amount of solid particles to adhere to it, resulting in a significant reduction in the air flow area. It needs to be manually cleaned regularly, which is inconvenient to use. Therefore, a catalytic burner feeding mechanism is proposed to address the above problems. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a feeding mechanism for a catalytic burner, which can filter solid particles in the exhaust gas through the filter plate in the exhaust gas filter box. When the air pump stops working, most of the solid particles will fall onto the closing mechanism under the action of gravity, and at the same time the plate driving mechanism works to drive the filter plate to swing in the swinging mouth, and further shake off the solid particles by means of motion vibration, thereby playing a cleaning role. In addition, the closing mechanism can be opened regularly for slag discharge, and a reverse airflow can be pumped into the air duct through the air pump at the same time, so that the solid particles on the filter plate are further blown off by the airflow, and the discharge of the solid particles is facilitated, which solves the technical problem in the prior art that the filter screen is prone to adhere to a large amount of solid particles after long-term use, resulting in a significant reduction in the air flow area, and requires manual cleaning, which brings inconvenience to use.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A catalytic burner feeding mechanism includes an exhaust gas filter box, which is used to filter the exhaust gas passing through, an air pump, which is connected to the exhaust gas filter box through a connecting pipe, and a feeding pipe, which is connected to the air pump output port through a connecting pipe, wherein the exhaust gas filter box includes a box shell, an air duct plate is provided inside the box shell, an air duct is formed between the air duct plate and the box shell, a group of swing openings are opened on the air duct plate, in which a filter plate rotatably connected to the box shell is provided, a plate driving mechanism for driving the filter plate is installed on the outside of the air duct plate, and a closing mechanism is installed on the inside of the bottom of the air duct plate.

[0007] Through the above-mentioned structural form, the filter plate in the exhaust gas filter box filters the solid particles in the exhaust gas. When the air pump stops working, most of the solid particles will fall onto the closing mechanism under the action of gravity, and at the same time the plate driving mechanism works to drive the filter plate to swing in the swinging mouth, and further shake off the solid particles through the motion vibration, thereby playing a cleaning role. In addition, the closing mechanism can be opened regularly for slag discharge, and the air pump can simultaneously pump a reverse airflow into the air duct, so as to further blow off the solid particles on the filter plate through the airflow, and facilitate the discharge of solid particles.

[0009] Through the above-mentioned structural form, the filter plate can be rotatably connected to the box shell as a whole, and different filtering requirements can be met by replacing different filter screens.

[0010] In a possible implementation, an airtight elastic sealing membrane is provided between the inner wall of the swing opening and the plate frame, and when the plate frame moves to the uppermost side, the two elastic sealing membranes on the lower side are in a tensioned state.

[0011] Through the above-mentioned structural form, the elastic closing membrane can ensure the air tightness at the swing opening, avoiding the poor air tightness of the internal air duct caused by the opening of the swing opening and affecting the flow direction of the airflow, and when the plate frame moves to the uppermost side, the lower elastic closing membrane is in a taut state, which can ensure that solid particles will not accumulate in the folds of the elastic closing membrane.

[0012] In a possible implementation, the panel driving mechanism includes a first hinged seat mounted on the air duct panel, a first electric telescopic rod is rotatably connected to the first hinged seat, and an end of the first electric telescopic rod is rotatably connected to the panel frame.

[0015] Through the above-mentioned structural form, the second electric telescopic rod is used to drive the closing plate to rotate. When exhaust gas filtering is performed, the closing plate is pressed against the air duct plate to ensure the air tightness of the internal air duct. When slag cleaning is performed, the closing plate rotates and separates from the air duct plate, so that solid particles can be discharged.

[0016] In a possible implementation, a slag discharge port communicating with the bottom of the air duct plate is provided on the box shell, and a slag guide plate located below the closing plate is installed on the box shell.

[0017] With the above-mentioned structural form, the solid particles sliding down from the closing plate will fall onto the slag guide plate and be discharged from the slag discharge port through the slag guide plate.

[0018] In a possible implementation, an air outlet and an air inlet are respectively installed on the box shell, and both the air outlet and the air inlet are communicated with the air duct.

[0019] The above-mentioned structural form provides the necessary structural basis for the inflow and discharge of exhaust gas, and can form a complete air passage, allowing the exhaust gas to flow out after being filtered through the filter plate.

[0020] In a possible implementation, a one-way valve is installed at the outlet of the feeding pipe, and the one-way valve only allows air flow to flow toward the outlet of the feeding pipe.

[0021] With the above-mentioned structural form, the one-way valve can be used to prevent the exhaust gas fed into the catalytic burner from flowing out through the feeding pipe.

A group of swing openings 121 are opened on the air duct plate 12, in which a filter plate 13 is provided, which is rotatably connected to the box shell 11. A plate driving mechanism 14 for driving the filter plate 13 is installed on the outside of the air duct plate 12. The bottom of the air duct plate 12 A closing mechanism 15 is installed on the inner side. Through the above-mentioned structural form, the filter plate 13 in the exhaust gas filter box 1 filters the solid particles in the exhaust gas. When the air pump 2 stops working, most of the solid particles will fall onto the closing mechanism 15 under the action of gravity, and at the same time, the plate driving mechanism 14 works to drive the filter plate 13 to swing in the swinging mouth 121, and further shake off the solid particles through the motion vibration, thereby playing a cleaning role. In addition, the closing mechanism 15 can be opened regularly for slag discharge, and the air pump 2 can be used to pump a reverse airflow to the air duct synchronously, so as to further blow off the solid particles on the filter plate 13 through the airflow, and facilitate the discharge of solid particles.

[0032] Among them, an airtight elastic sealing membrane 134 is attached between the inner wall of the swing opening 121 and the plate frame 131, and when the plate frame 131 moves to the uppermost side, the two elastic sealing membranes 134 located on the lower side are in a taut state. Through the above-mentioned structural form, the elastic sealing membrane 134 can ensure the air tightness at the swing opening 121, avoiding the poor air tightness of the internal air duct caused by the opening of the swing opening 121 and affecting the flow direction of the airflow, and when the plate frame 131 moves to the uppermost side, the lower elastic sealing membrane 134 is in a taut state, which can ensure that solid particles will not accumulate in the folds of the elastic sealing membrane 134.

[0033] like Figure 3 As shown, the filter plate 13 includes a plate frame 131, in which a filter screen 132 is detachably installed. The upper ends of the plate frame 131 are rotatably connected to the box shell 11 through fixedly connected rotating shafts 133. Through the above-mentioned structural form, the filter plate 13 as a whole can be rotatably connected to the box shell 11, and different filtering requirements can be met by replacing different filter screens 132.

[0034] In addition, the plate driving mechanism 14 includes a first hinged seat 141 installed on the air duct plate 12, and a first electric telescopic rod 142 is rotatably connected to the first hinged seat 141. The rod end of the first electric telescopic rod 142 is rotatably connected to the plate frame 131. Through the above-mentioned structural form, the operation of the first electric telescopic rod 142 can drive one end of the plate frame 131 to rotate to form a swinging effect, thereby shaking off solid particles.

[0035] like Figure 4 As shown, the closing mechanism 15 includes a connecting plate 151 and a second hinged seat 153 installed on the inner wall of the air duct plate 12. The connecting plate 151 is rotatably connected to the closing plate 152, and the second hinged seat 153 is rotatably connected to the second electric telescopic rod 154. The rod end of the second electric telescopic rod 154 is rotatably connected to the closing plate 152. Through the above-mentioned structural form, the second electric telescopic rod 154 drives the closing plate 152 to rotate. When exhaust gas filtering is performed, the closing plate 152 is against the air duct plate 12 to ensure the air tightness of the internal air duct. When slag cleaning is performed, the closing plate 152 rotates and separates from the air duct plate 12, so that solid particles can be discharged.

[0036] In addition, a slag discharge port 111 is connected to the bottom of the box shell 11 and the air duct plate 12, and a slag guide plate 17 is installed on the box shell 11 below the closing plate 152. Through the above-mentioned structural form, solid particles sliding down from the closing plate 152 will fall onto the slag guide plate 17 and be discharged from the slag discharge port 111 through the slag guide plate 17.

[0037] like Figure 2 As shown, an air outlet 161 and an air inlet 162 are respectively installed on the box shell 11, and both the air outlet 161 and the air inlet 162 are connected to the air duct. Through the above-mentioned structural form, the necessary structural basis is provided for the inflow and discharge of exhaust gas, and a complete air duct can be formed to allow the exhaust gas to flow out after being filtered through the filter plate 13.

[0038] like Figure 1 As shown, a one-way valve 41 is installed at the outlet of the feeding pipe 4. The one-way valve 41 only allows the air flow to flow to the outlet of the feeding pipe 4. Through the above-mentioned structural form, the one-way valve 41 can be set to prevent the exhaust gas sent into the catalytic burner from flowing out through the feeding pipe 4.

[0039] The use principle and use process of this utility model:

[0040] The filter plate 13 in the exhaust gas filter box 1 filters the solid particles in the exhaust gas. When the air pump 2 stops working, most of the solid particles will fall onto the closing mechanism 15 under the action of gravity, and at the same time, the plate driving mechanism 14 works to drive the filter plate 13 to swing in the swinging mouth 121, and further shake off the solid particles through motion vibration, thereby playing a cleaning role. Specifically, the first electric telescopic rod 142 works to drive one end of the plate frame 131 to rotate to form a swinging effect, thereby shaking off the solid particles.

[0041] On the basis of the above structure, the elastic sealing membrane 134 can ensure the air tightness at the swing opening 121, avoiding the poor air tightness of the internal air duct caused by the opening of the swing opening 121 and affecting the flow direction of the airflow, and when the plate frame 131 moves to the uppermost side, the lower elastic sealing membrane 134 is in a taut state, which can ensure that solid particles will not accumulate in the folds of the elastic sealing membrane 134.

[0042] In addition, when exhaust gas filtering is performed, the closing plate 152 is pressed against the air duct plate 12 to ensure the air tightness of the internal air duct. When slag cleaning is performed, the closing plate 152 rotates and separates from the air duct plate 12, so that solid particles can be discharged, and the air pump 2 simultaneously pumps a reverse airflow to the air duct, which further blows off the solid particles on the filter plate 13 through the airflow, and facilitates the discharge of solid particles.
