Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to an environmentally friendly kiln waste gas treatment device. Background Technology

[0002] In kiln exhaust gas treatment systems, filtration devices are key components for removing particulate matter from the exhaust gas. Their core principle is to trap dust in the exhaust gas using filter media. However, with increased operating time, dust gradually accumulates on the filter media surface, leading to increased filtration resistance, decreased ventilation efficiency, and even equipment shutdown or excessive emissions due to blockage. Therefore, timely monitoring of the filter's blockage status and triggering maintenance prompts is crucial for ensuring the stable operation of the exhaust gas treatment system.

[0003] Currently, the clogging monitoring and maintenance of traditional filter devices relies solely on manual periodic inspections to observe pressure gauge readings to determine the clogging status. However, the pressure gauge reflects the overall pressure difference of the filter device and cannot directly correlate with the actual degree of clogging of the filter media. Furthermore, manual inspections suffer from poor real-time performance and a high risk of missed detections.

[0004] Pressure sensors in traditional baghouse dust collectors are usually installed on the inlet and outlet pipes of the equipment. When the pressure difference exceeds the threshold, the filter bag may be severely clogged, leading to untimely maintenance and affecting production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is the lack of timely maintenance of filter materials in the existing technology. To address this, we propose an environmentally friendly kiln exhaust gas treatment device.

[0006] To achieve the above objectives, this application adopts the following technical solution: an environmentally friendly kiln exhaust gas treatment device, comprising a kiln, an exhaust gas assembly installed on one side of the kiln, the exhaust gas assembly including an exhaust gas pipe, an air pump installed at the top of the exhaust gas pipe, an assembly pipe fixedly connected to the middle of the exhaust gas pipe, a filter disc built into the assembly pipe, a plurality of support rollers fixedly connected to one side of the top of the filter disc, an assembly cylinder sleeved at the end of the support rollers away from the filter disc, a moving disc fixedly connected to one end of the support rollers inside the assembly cylinder, a return spring provided between the moving disc and the bottom of the inner cavity of the assembly cylinder, a contact rod fixedly connected to one side of the top of the filter disc, and a pressure sensor provided at the end of the contact rod away from the filter disc.

[0007] Preferably, the surface of the kiln is fixed with multiple sets of fixing frames.

[0008] Preferably, a support frame is fixedly connected to one side of the exhaust pipe, and the bottom of the support frame is fixedly connected to the kiln.

[0009] Preferably, the pressure sensor is fixedly connected to a connecting seat at its tail end, and the end of the connecting seat away from the pressure sensor is fixedly connected to the inner wall of the assembly tube.

[0010] Preferably, a connecting ring is fitted and fixed around the filter disc, and the outer ring wall of the connecting ring is slidably connected to the inner wall of the assembly tube.

[0011] Preferably, multiple guide seats are fixedly connected around the connecting ring, and multiple guide grooves are opened on the inner wall of the assembly tube, with the guide seats slidably connected to the groove walls.

[0012] Preferably, one end of the return spring contacts the moving disc, and the other end of the return spring is sleeved and fixed with a connecting cylinder, the top of the connecting cylinder being fixedly connected to the bottom of the inner cavity of the assembly cylinder.

[0013] Preferably, a fixing seat is fixedly connected to the end of the assembly cylinder away from the filter disc, and one end of the fixing seat is fixedly connected to the inner wall of the assembly tube.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This utility model's environmentally friendly kiln exhaust gas treatment device consists of a kiln, exhaust gas components, etc. An air pump drives the exhaust gas through a filter disc inside the assembly pipe for purification. The filter disc's surrounding connecting rings, guide seats, and grooves enable sliding. A top support roller and a return spring form an elastic structure, and a contact rod and pressure sensor work together to monitor blockages. When dust accumulates on the filter disc surface and resistance increases, the air pump's suction overcomes the return spring's force, causing the filter disc to move and the contact rod to touch the pressure sensor. An electrical signal is then wirelessly transmitted to the control center to trigger an alarm and prompt maintenance.

[0016] Compared to traditional devices that rely on inlet and outlet pressure differences to determine blockage, this equipment offers strong real-time performance, accurately sensing the filter disc's blockage status and preventing excessive clogging. Automated processes replace manual inspections, significantly reducing labor costs and the risk of missed detections, ensuring stable system operation. Structurally, the guide structure ensures stable movement, the return spring facilitates quick reset after cleaning, and the combination of the contact rod and sensor provides reliable trigger signals. The device offers flexible installation, excellent compatibility with both new and existing equipment, requires no large-scale modifications, effectively reducing upgrade costs, and is widely applicable to various kiln exhaust gas treatment scenarios, combining technological advancement with market applicability.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] Reference Figures 1 to 5 As shown, this utility model provides an environmentally friendly kiln exhaust gas treatment device, including a kiln 1. Multiple sets of fixing frames 101 are fixed on the surface of the kiln 1. An exhaust gas assembly 2 is installed on one side of the kiln 1. The exhaust gas assembly 2 includes an exhaust gas pipe 201. A support frame 202 is fixedly connected to one side of the exhaust gas pipe 201. The bottom of the support frame 202 is fixedly connected to the kiln 1. An air pump 203 is installed on the top of the exhaust gas pipe 201. The exhaust gas generated by the operation of the kiln 1 is transported through the exhaust gas pipe 201, and the air pump 203 provides suction to drive the exhaust gas flow.

[0026] The exhaust pipe 201 is fixedly connected to the middle of the assembly pipe 204, which has a built-in filter disc 205. When the exhaust gas passes through the filter disc 205 in the assembly pipe 204, the filter disc 205 traps dust and other particulate matter in the exhaust gas, thus achieving preliminary purification.

[0027] A connecting ring 206 is fixedly fitted around the filter disc 205. The outer ring wall of the connecting ring 206 is slidably connected to the inner wall of the assembly tube 204. Multiple guide seats 207 are fixedly connected around the connecting ring 206. Multiple guide grooves 208 are formed on the inner wall of the assembly tube 204. The guide seats 207 are slidably connected to the groove walls of the guide grooves 208. Multiple support rollers 209 are fixedly connected to one side of the top of the filter disc 205. An assembly cylinder 210 is fitted onto the end of the support roller 209 away from the filter disc 205. A moving disc 2 is fixedly connected to the end of the support roller 209 inside the assembly cylinder 210. 11. A return spring 212 is provided between the moving disc 211 and the bottom of the inner cavity of the assembly cylinder 210. One end of the return spring 212 contacts the moving disc 211, and the other end of the return spring 212 is sleeved and fixed to a connecting cylinder 213. The top of the connecting cylinder 213 is fixedly connected to the bottom of the inner cavity of the assembly cylinder 210. A fixing seat 214 is fixedly connected to the end of the assembly cylinder 210 away from the filter disc 205. One end of the fixing seat 214 is fixedly connected to the inner wall of the assembly tube 204. As the usage time increases, the dust accumulated on the surface of the filter disc 205 increases, causing the filtration resistance to rise continuously. At this time, the suction force of the air pump 203 on the filter disc 205 increases. When the suction force is sufficient to overcome the elastic force of the return spring 212 on the support roller 209, the filter disc 205 begins to move along the sliding track formed by the guide seat 207 and the guide groove 208.

[0028] A contact rod 215 is fixedly connected to one side of the top of the filter disc 205. A pressure sensor 216 is installed at the end of the contact rod 215 away from the filter disc 205. A connecting seat 217 is fixedly connected to the tail of the pressure sensor 216. The end of the connecting seat 217 away from the pressure sensor 216 is fixedly connected to the inner wall of the assembly tube 204. As the filter disc 205 moves, the contact rod 215 gradually approaches the pressure sensor 216. When the filter disc 205 moves to a certain position, the contact rod 215 touches the pressure sensor 216, triggering the pressure sensor 216 to generate an electrical signal. This electrical signal is transmitted to the control center via a wireless unit. After receiving the signal, the control center determines that the filter disc 205 is clogged and immediately issues a maintenance reminder, reminding staff to clean or replace the filter disc 205 in a timely manner to avoid equipment shutdown or excessive emissions due to severe clogging of the filter disc 205.

[0029] Traditional devices rely on the pressure difference between the inlet and outlet to determine blockage, which is subject to lag. This device directly triggers the pressure sensor 216 by moving the filter disc 205 under force, thereby sensing the blockage status of the filter disc 205 in real time, accurately locating the blockage problem, and avoiding excessive blockage of the filter disc 205 due to untimely monitoring. It realizes a fully automated process from blockage detection to alarm prompt, eliminating the need for frequent manual inspections, reducing labor costs and the risk of missed detections, improving the real-time performance and accuracy of monitoring, and ensuring the continuous and stable operation of the waste gas treatment system.

[0030] The reset spring 212 provides reset capability for the filter disc 205, ensuring that the filter disc 205 can quickly return to its initial working position after cleaning or replacement; the setting of the contact rod 215 and the pressure sensor 216 makes the blockage signal triggering simple and reliable. The device can be flexibly installed in various kiln exhaust gas treatment systems, has good compatibility with the transformation of new and old equipment, does not require large-scale modification of the original system, reduces equipment upgrade costs, and has a wide range of applications.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
